The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 112
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.
Claim 6 is 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 6 recites “the convex fixing plate” which lacks antecedent basis. For the purpose of examination, claim 6 will be treated as depending from claim 5.
Claim Rejections - 35 USC § 102
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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.

Claim Rejections - 35 USC § 103
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 nonobviousness.
Claim(s) 5, 7-9, and 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lerman et al (US 2025/0234894) in view of Bayer (“Snap-Fit joints for Plastics”).
Regarding claim 5, Lerman discloses vertical fixing plates are respectively provided at two sides of the fixing frame; a convex fixing plate is provided at a front side of the fixing vertical plate; a side of the convex fixing plate close to the second fixing rack is protruded; a frame fixing hole provided on the convex fixing plate; a stud hole formed in the second vertical rod; and the stud hole corresponds to the frame fixing hole (shown in annotated figure below).

Lerman lacks the frame limiting fastener and frame limiting hole.
Bayer evidences a frame limiting hole and frame limiting fastener for making a connections (figure 3 of page 5).
It would have been obvious to one of ordinary skill in the art to have provided Lerman with a snap-fitting as disclosed by Bayer in the form of a frame limiting fastener are provided on the convex fixing plate; a frame limiting hole are formed in the second vertical rod; and the frame limiting fastener is buckled into the frame limiting hole in order to facilitate assembly of the device and provide robust connection.
Regarding claim 7, Lerman discloses 7. The slush machine according to claim 3, wherein a support flange is provided at an edge of the chassis; the support flange is protruded from an outer sidewall of the chassis; support pedestals are respectively provided at an inner bottom of the first side vertical plate and an inner bottom of the second side vertical plate.

Lerman is silent concerning a fixing hole as claimed.
Bayer discloses a bottom fixing hole is formed in a support pedestal; a bottom of the support flange abuts against the support pedestal; and the chassis is fixed in the bottom fixing hole (connection shown in figure 3 at page 5).
It would have been obvious to one of ordinary skill in the art to have provided Lerman with the fixing hole and abutting connection as taught by Bayer in order to provide robust and quick connection between said components.
Regarding claims 8 and 9, Lerman discloses the first and second vertical support plates are joined at a front (U-shaped feature near 118 of figure 1) but is silent concerning a means of fixing.
Bayer discloses joining support portions with protrusions and connecting holes as well as limiting bumps (shown in various snap fit connections, e.g. fig 3 of page 5).
It would have been obvious to one of ordinary skill in the art to have provided Lerman with the snap-fit connection as taught by Lerman in order to provide rapid and inexpensive connection of the components.
Regarding claim 11, Lerman discloses a bracket (118) is further provided under the discharge cartridge (116); but lacks a connecting hook and hanger.
Bayer discloses connecting structures including hooks, hangers, slots, holes, and plates (shown in various snap fit connections, e.g. fig 3 of page 5).
It would have been obvious to one of ordinary skill in the art to have provided Lerman with the snap-fit connection as taught by Lerman in order to provide rapid and inexpensive connection of the components.
Claim(s) 6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lerman et al (US 2025/0234894), in view of Bayer (“Snap-Fit joints for Plastics”), and in further view of Chhajed et al (US 11,719,486).
As was noted above, for the purpose of examination claim 6 is treated as depending from claim 5.
Regarding claim 6, Lerman, as modified, discloses the slush machine of claim 5, but lacks the side baffles as claimed.
Chhajed discloses a fixing frame further comprises a frame plate and side baffles; the side baffles are respectively provided at a left side and a right side of the frame plate, and extend away from the convex fixing plate; the side baffles enclose a heat dissipation channel; condenser fixing plates are respectively provided at an upper side and a lower side of the frame plate; the end plate is fixed on the condenser fixing plate; a side of the frame plate away from the condenser is provided with a fan fixing hole and a fan limiting post; the refrigeration assembly further comprises a cooling fan; and the cooling fan is inserted into the fan limiting post and fixed on the fan fixing hole.

It would have been obvious to one of ordinary skill in the art to have provided Lerman with the frame plate and side baffles of Chhajed in order to securely fit the fan and condenser to the assembly. Moreover as Lerman is silent concerning precise means for fixing the fan, however some solution is necessarily present it falls to mere selection of an identified predictable solution such as that provided by Chhajed in order to make or use the invention.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Lerman et al (US 2025/0234886) slush machine.
Tinsler (US 4,471,63) condenser mounting features.
Kawabata (US 10,365,028) condenser and fan mounting features.
