Office Action

§103 §112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the “an outdoor unit component, and a mounting member connected to an upper part of the detection member and corresponding to the access opening, the mounting member being insertion-fitted or snap- fitted with the base assembly, and a support member is configured to support and be connected to the indoor heat exchanger” must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and (C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: “a water level detection device including: a detection member” in claim 28. “a mounting member” in claim 28. “an insertion member” in claim 29. “a joining member” in claim 30. “a heat insulation member” in claim 34. Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 28-30 and 34 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Regarding claim 28, “the water treatment system further includes a water level detection device including: a detection member located in the accommodation groove”. The term “device and member” invokes a claim interpretation governed under 35 U.S.C. 112(f) (pre-AIA 35 U.S.C. 112, sixth paragraph), which requires a review of the specification to determine the appropriate structure, material or act to carry out the claimed limitation. However, the specification as originally filed, fails to describe a corresponding structure or technique by which a water level detection device including: a detection member located in the accommodation groove. A mere restatement of the function does not suffice as a statement of structure. Thus, it does not appear that applicant had possession of the claimed invention because the specification does not disclose a structure which is capable of detecting a water level. When a description of the structure, material or act is not provided or is not sufficient to perform the entire claimed function, or no association between the structure and the claimed function can be found in the specification, the written description fails to clearly define the boundaries of the claim. Regarding claim 28, “a mounting member connected to an upper part of the detection member and corresponding to the access opening”. The term “member” invokes a claim interpretation governed under 35 U.S.C. 112(f) (pre-AIA 35 U.S.C. 112, sixth paragraph), which requires a review of the specification to determine the appropriate structure, material or act to carry out the claimed limitation. However, the specification as originally filed, fails to describe a corresponding structure or technique by which a mounting member connected to an upper part of the detection member and corresponding to the access opening. A mere restatement of the function does not suffice as a statement of structure. Thus, it does not appear that applicant had possession of the claimed invention because the specification does not disclose a structure which is capable of being connected to an upper part of the detection member and corresponding to the access opening. When a description of the structure, material or act is not provided or is not sufficient to perform the entire claimed function, or no association between the structure and the claimed function can be found in the specification, the written description fails to clearly define the boundaries of the claim. Regarding claim 29, “the base assembly includes an insertion member provided at an edge of the base assembly and extending upwardly”. The term “member” invokes a claim interpretation governed under 35 U.S.C. 112(f) (pre-AIA 35 U.S.C. 112, sixth paragraph), which requires a review of the specification to determine the appropriate structure, material or act to carry out the claimed limitation. However, the specification as originally filed, fails to describe a corresponding structure or technique by which an insertion member is provided at an edge of the base assembly and extending upwardly. A mere restatement of the function does not suffice as a statement of structure. Thus, it does not appear that applicant had possession of the claimed invention because the specification does not disclose a structure which is capable of being provided at an edge of the base assembly and extending upwardly. When a description of the structure, material or act is not provided or is not sufficient to perform the entire claimed function, or no association between the structure and the claimed function can be found in the specification, the written description fails to clearly define the boundaries of the claim. Regarding claim 30, “the humidification device includes a joining member joined to the mounting post and connected to the mounting post by a fastener”. The term “member” invokes a claim interpretation governed under 35 U.S.C. 112(f) (pre-AIA 35 U.S.C. 112, sixth paragraph), which requires a review of the specification to determine the appropriate structure, material or act to carry out the claimed limitation. However, the specification as originally filed, fails to describe a corresponding structure or technique by which a joining member joined to the mounting post and connected to the mounting post by a fastener. A mere restatement of the function does not suffice as a statement of structure. Thus, it does not appear that applicant had possession of the claimed invention because the specification does not disclose a structure which is capable of being joined to the mounting post and connected to the mounting post by a fastener. When a description of the structure, material or act is not provided or is not sufficient to perform the entire claimed function, or no association between the structure and the claimed function can be found in the specification, the written description fails to clearly define the boundaries of the claim. Regarding claim 34, “a heat insulation member wrapping around an outer wall of the second base member”. The term “member” invokes a claim interpretation governed under 35 U.S.C. 112(f) (pre-AIA 35 U.S.C. 112, sixth paragraph), which requires a review of the specification to determine the appropriate structure, material or act to carry out the claimed limitation. However, the specification as originally filed, fails to describe a corresponding structure or technique by which a heat insulation member is wrapped around an outer wall of the second base member. A mere restatement of the function does not suffice as a statement of structure. Thus, it does not appear that applicant had possession of the claimed invention because the specification does not disclose a structure which is capable of being wrapped around an outer wall of the second base member. When a description of the structure, material or act is not provided or is not sufficient to perform the entire claimed function, or no association between the structure and the claimed function can be found in the specification, the written description fails to clearly define the boundaries of the claim. The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION. —The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 28-30 and 34 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim limitations “a water level detection device including: a detection member, an mounting member, an insertion member, an joining member and a heat insulation member” invokes 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. However, the written description fails to disclose the corresponding structure, material, or acts for performing the entire claimed function and to clearly link the structure, material, or acts to the function. The specification fails discloses the corresponding structure that achieves the claimed function in sufficient detail that one of ordinary skill in the art can reasonably conclude that the inventor possessed the claim subject matter at the time of filing. Therefore, the claim is indefinite and is rejected under 35 U.S.C. 112(b) or pre-AIA 35 U.S.C. 112, second paragraph. Applicant may: (a) Amend the claim so that the claim limitation will no longer be interpreted as a limitation under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph; (b) Amend the written description of the specification such that it expressly recites what structure, material, or acts perform the entire claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (c) Amend the written description of the specification such that it clearly links the structure, material, or acts disclosed therein to the function recited in the claim, without introducing any new matter (35 U.S.C. 132(a)). If applicant is of the opinion that the written description of the specification already implicitly or inherently discloses the corresponding structure, material, or acts and clearly links them to the function so that one of ordinary skill in the art would recognize what structure, material, or acts perform the claimed function, applicant should clarify the record by either: (a) Amending the written description of the specification such that it expressly recites the corresponding structure, material, or acts for performing the claimed function and clearly links or associates the structure, material, or acts to the claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (b) Stating on the record what the corresponding structure, material, or acts, which are implicitly or inherently set forth in the written description of the specification, perform the claimed function. For more information, see 37 CFR 1.75(d) and MPEP §§ 608.01(o) and 2181. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or non-obviousness. Claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over Silva et al (BR PI0622207 A2, hereinafter Silva) in view of Xu et al (CN 217178943 U, hereinafter Xu) and Zhang (CN 113834172 A, hereinafter Zhang). Regarding claim 16, Silva teaches a window air conditioner (window air conditioning unit 120) comprising: an indoor unit component (an evaporator in the indoor space, paragraph ) including: an indoor unit housing (housing, figures 1-2); an indoor heat exchanger (evaporator 60) arranged in the indoor unit housing (figure 2); and a base assembly (drain pan 54, figures 5A/5B) arranged below the indoor heat exchanger (as shown on figures 5A/5B) and provided with an accommodation groove (collection portion 56, figures 5A/5B) that is located in the indoor unit housing at a side of the indoor heat exchanger (it is interpreted that the drain pan 54 would be located below the evaporator 60 at an indoor portion of the air conditioning unit); an outdoor unit component (condenser 124). Silva teaches the invention as described above but fail to teach a water treatment system including: a filter assembly including a first filter device and a second filter device that are both arranged in the accommodation groove, a water outlet of the first filter device being in communication with the accommodation groove, and a water inlet of the second filter device being in communication with the accommodation groove. However, Xu teaches a water treatment system (filtering process of the condensed water, so as to ensure the clean of the condensed water, it also has the function of deodorizing, abstract) including: a filter assembly (filter assembly 9) including a first filter device (guide assembly 21) and a second filter device (filter part 17) that are both arranged in the accommodation groove (water receiving plate main body 1), a water outlet of the first filter device being in communication with the accommodation groove (a flow guide component 21 mounted on the water receiving disc main body 1 for guiding and collecting condensed water, paragraph 0008), and a water inlet of the second filter device being in communication with the accommodation groove (air conditioner evaporator defrosting pan further comprises a filter assembly 9, a filter part 17, paragraphs 0016-0017). Therefore, it would have been obvious to a person skilled in the art before the effective filing date of the invention to modify the air conditioner in the teachings of Silva to include a water treatment system including: a filter assembly including a first filter device and a second filter device that are both arranged in the accommodation groove, a water outlet of the first filter device being in communication with the accommodation groove, and a water inlet of the second filter device being in communication with the accommodation groove in view of the teachings of Xu in order to yield the predictable result of ensuring the clean of the condensed water and also has the function of deodorizing. The combined teachings teach the invention as described above but fail to teach a water consumption assembly including a humidification device and a spray device, a water inlet of the humidification device being in communication with the accommodation groove, a water inlet of the spray device being in communication with a water outlet of the second filter device, and a minimum filter pore size of the second filter device being smaller than a spray pore size of the spray device. However, Zhang teaches a water consumption assembly (figure 2) including a humidification device (ultrasonic atomizer 23) and a spray device (nozzle 9), a water inlet of the humidification device (water outlet pipe 19) being in communication with the accommodation groove (atomizing cavity 22), a water inlet of the spray device (atomizing pipe 24) being in communication with a water outlet of the second filter device (of water tank 16, as shown on figure 2), and a minimum filter pore size of the second filter device being smaller than a spray pore size of the spray device (it is interpreted that the size of atomizing pipe 24 is smaller than the pipe of the nozzle 9). Therefore, it would have been obvious to a person skilled in the art before the effective filing date of the invention to modify the air conditioner in the combined teachings to include a water consumption assembly including a humidification device and a spray device, a water inlet of the humidification device being in communication with the accommodation groove, a water inlet of the spray device being in communication with a water outlet of the second filter device, and a minimum filter pore size of the second filter device being smaller than a spray pore size of the spray device in view of the teachings of Zhang in order to yield the predictable result of allowing the decomposition and purification of the harmful gas in the indoor air is realized. Claims 17-18 and 28 are rejected under 35 U.S.C. 103 as being unpatentable over Silva as modified by Xu and Zhang, as applied to claim 16 above, and in further view of Bae et al (KR 20210048464 A, hereinafter Bae). Regarding claim 17, the combined teachings teach the invention as described above but fail to teach wherein: the first filter device includes a filter box; and a top of the filter box is opened to form a water inlet of a filter of the first filter device to receive water flowing down from above. However, Bae teaches wherein: the first filter device (2100) includes a filter box (2100, figure 6); and a top of the filter box (as shown on figure 6) is opened to form a water inlet (valve hole 2111) of a filter of the first filter device (figure 6) to receive water flowing down from above (a heat exchange assembly disposed between the cabinet assemblies 100 to exchange heat exchange between the sucked indoor air and a refrigerant, and a humidifying assembly 2000 disposed in the cabinet assembly 100 to provide moisture to the room, paragraph 0094 of Bae). Therefore, it would have been obvious to a person skilled in the art before the effective filing date of the invention to modify the air conditioner in the combined teachings to include wherein: the first filter device includes a filter box; and a top of the filter box is opened to form a water inlet of a filter of the first filter device to receive water flowing down from above in view of the teachings of Bae in order to yield the predictable result of converting water from the water tank into steam and supplies it to the discharge passage. Regarding claim 18, the combined teachings teach wherein the filter box (2000 including 2110, figures 3 and 5 of Bae) is located below a side tubing of the indoor heat exchanger (a heat exchange assembly disposed between the cabinet assemblies 100 to exchange heat exchange between the sucked indoor air and a refrigerant, and a humidifying assembly 2000 disposed in the cabinet assembly 100 to provide moisture to the room, paragraph 0094 of Bae). Regarding claim 28, the combined teachings teach wherein: the indoor unit (indoor unit, figure 1 of Bae) housing has an access opening (via door assembly 200, figure 2 of Bae); and the water treatment system (door assembly 200 of Bae) further includes a water level detection device (sensors 2360/2370 of Bae) including: a detection member located in the accommodation groove (lower portion of sensors, figure 19 of Bae); and a mounting member (upper portion of sensors 2360/2370, figure 19 of Bae) connected to an upper part of the detection member (as shown on figure 19 of Bae) and corresponding to the access opening (as shown on figures 2-3 of Bae), the mounting member being insertion-fitted (interpreted to be inserted and attached to housing 2310, figure 19) or snap- fitted with the base assembly (base 130 of Bae). Claim 19 is rejected under 35 U.S.C. 103 as being unpatentable over Silva as modified by Xu, Zhang and Bae, as applied to claim 17 above, and in further view of Huang (CN 107110518 A, hereinafter Huang). Regarding claim 19, the combined teachings teach the invention as described above but fail to teach wherein: the water treatment system further includes a recovery assembly configured to recover condensate water from the outdoor unit component, the recovery assembly including a water- guiding tube having a water outflowing end extending to the indoor unit component and located above the filter box; and the base assembly is provided with a tube clamp for limiting a position of the water- guiding tube. However, Huang teaches wherein: the water treatment system (water cooling unit 50 provided in the outdoor compartment 12, paragraph 0010) further includes a recovery assembly (water cooling unit 50) configured to recover condensate water from the outdoor unit component (an outdoor compartment 12, an indoor front air intake port 13, two side air intake port 14 are respectively set on the two side of the shell, an indoor air outlet 15, for storing a predetermined amount of cooling water in the water tank 16, as the cooling water filled in the water inlet 16 of the water tank 17, paragraph 0009), the recovery assembly (water cooling unit 50) including a water- guiding tube (cooling water pipe 56) having a water outflowing end extending to the indoor unit component (cooling water pipe 56 leading to the top of basin 52. set a predetermined amount of the working fluid to flow through heat exchange tube 55 so that the refrigerant and the cooling water for efficient heat exchange process, paragraph 0010) and located above the filter box (above basin 54, as shown on figure 28); and the base assembly is provided with a tube clamp for limiting a position of the water- guiding tube (one of ordinary skill in the art would determine that the base of housing 10 would have a structure to restrict the movement of cooling pipe 56 so that the cooling water is maintained for efficient heat exchange process). Therefore, it would have been obvious to a person skilled in the art before the effective filing date of the invention to modify the air conditioner in the combined teachings to include a recovery assembly configured to recover condensate water from the outdoor unit component, the recovery assembly including a water- guiding tube having a water outflowing end extending to the indoor unit component and located above the filter box; and the base assembly is provided with a tube clamp for limiting a position of the water- guiding tube in view of the teachings of Huang in order to yield the predictable result of so that the refrigerant and the cooling water for efficient heat exchange process, so as to reduce the temperature of the refrigerant Further, it is understood, claim 19 includes an intended use recitation, for example “…configured to...”. The applicant is reminded that a recitation with respect to the manner which a claimed apparatus is intended to be does not differentiate the claimed apparatus from a prior art apparatus satisfying the structural limitations of the claims, as is the case here. While features of an apparatus may be recited either structurally or functionally, the claims are directed to an apparatus must be distinguished from the prior art in terms of structure rather than function. Claims 20-22 are rejected under 35 U.S.C. 103 as being unpatentable over Silva as modified by Xu, Zhang and Bae, as applied to claim 17 above, and in further view of Xing et al (US 20210332988 A1, hereinafter Xing). Regarding claim 20, the combined teachings teach the invention as described above but fail to teach wherein at least one of a bottom wall or a side wall of the filter box is formed with a filter hole as the water outlet of the first filter device. However, Xing teaches wherein at least one of a bottom wall (at the bottom of water receiving pan 400, as shown on figure 13) or a side wall of the filter box (water receiving pan 400) is formed with a filter hole (water hole 5402) as the water outlet of the first filter device (paragraph 0086). Therefore, it would have been obvious to a person skilled in the art before the effective filing date of the invention to modify the air conditioner in the combined teachings to include wherein at least one of a bottom wall or a side wall of the filter box is formed with a filter hole as the water outlet of the first filter device in view of the teachings of Xing in order to yield the predictable result such that the condensation water can be drained smoothly. Regarding claim 21, the combined teachings teach wherein the water outlet of the first filter device (paragraph 0086 of Xing) is formed at a bottom of the filter box (at the bottom of water receiving pan 400, as shown on figure 13 of Xing), and the first filter device (chassis 100 of Xing) includes a filter (filter screen 600 of Xing) arranged in the filter box (as shown on figure 10 of Xing).
