It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the door of KIM as modified with the first and second door configuration as taught by Salice for the purpose of having a door configuration which is meant to operated in a confined area. As a result of the Salice modification the second door would also be confined to the door structure of which mates and supports 6 of “JP 2019”, the scraper would also be coupled to the second door. Referring to claim 3: KIM as modified teaches the cleaner station of claim 1, wherein the scraper (3 Figs. 3, 6, and 7 of “JP 2019”) is coupled to the door structure which holds the door (6 Figs. 3 and 4 of “JP 2019”) and protrudes outward (3b shown protruding outwards in Fig. 6). But is silent on wherein the door comprises: a first door hingedly coupled to the coupling surface; and a second door hingedly coupled to the first door, wherein the second door comprises: a second door main body hingedly coupled to the first door; and a second door outer wall surface formed at an outer end of the second door main body and configured to face a sidewall of the dust passage hole when the door blocks the dust passage hole, and wherein the scraper is coupled to the second door outer wall surface and protrudes outward from the second door outer wall surface. Salice teaches a similar configuration door (14 and 16 Fig. 3) further comprising a first door (14 Fig. 3) hingedly coupled to the coupling surface (surface of 26); and a second door (16 Fig. 3) hingedly coupled to the first door (14 Fig. 3), wherein the second door comprises: a second door main body (main body of 16 Fig. 3) hingedly coupled to the first door (14 Fig. 3); and a second door outer wall surface (end surface of 16 which faces the bottom of 26) formed at an outer end of the second door main body (main body of 16 Fig. 3) and configured to face a sidewall (sidewall of 26) of the similar configuration dust passage hole (hole of 26 which is closed by 14 and 16) when the door (14 and 16 Fig. 3) blocks the dust passage hole. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the door of KIM as modified with the first and second door configuration as taught by Salice for the purpose of having a door configuration which is meant to operated in a confined area. As a result of the Salice modification the second door would also be confined to the door structure of which mates and supports 6 of “JP 2019”, the scraper would also be coupled to the second door outer wall surface. Claim 7 is rejected under 35 U.S.C. 103 as being unpatentable over KIM (US 20210052121 A1) and “JP 2019” (JP 6570130 B2), as applied above in claim 1, and in further view of George (US 1212255 A).

George in an analogous scraper teaches it made of a felt material (“This invention relates to that type of fountain window washing appliances provided with detachable squeegee blades of rubber, felt or the like.” Lines 9-12). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the scraper of KIM as modified with the felt material as taught by George for the purpose of having a material suitable for cleaning that is also doesn’t damage the cleaning surface. Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over KIM (US 20210052121 A1) and “JP 2019” (JP 6570130 B2), as applied above in claim 1, and in further view of Farmer (US 4240176 A). Referring to claim 8: KIM as modified teaches the cleaner station of claim 1, but is silent on wherein the scraper comprises a brush. Farmer teaches wherein the analogous scraper comprises a brush (“In accordance with my invention there is provided a device for interchangeably holding a plurality of windshield cleaning tools, including a sponge, scraper, squeegee and brush” Col. 1, lines 20-23). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the scraper of KIM as modified with the brush material as taught by Farmer for the purpose of having a material suitable for cleaning that is also doesn’t damage the cleaning surface. Claim 10 is rejected under 35 U.S.C. 103 as being unpatentable over KIM (US 20210052121 A1) and “JP 2019” (JP 6570130 B2), as applied above in claim 4, and in further view of Junkins (US 20110017232 A1). Referring to claim 10: KIM as modified teaches the cleaner station of claim 4, and teaches wherein the second scraper (S2 Fig. 2-A inserted above of “JP 2019”) disposed in parallel (S2 runs parallel to 6) along the outer peripheral surface (outer peripheral surface of 6) of the door (6 Figs. 3 and 4 of “JP 2019”). But is silent on comprises a plurality of scraper teeth protruding at predetermined intervals. Junkins in an analogous scraper (15 Fig. 1) teaches a plurality of scraper teeth (21 Fig. 1) protruding at predetermined intervals (shown in Fig. 1). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the scraper of KIM as modified with the teeth as taught by Junkins for the purpose of having a material suitable for cleaning that is also doesn’t damage the cleaning surface.
