Regarding Claim 10, Yan shows (Figures 5, 6, 8, 9, 12, 16, 20, 24, and 25): An upper end (the right end of 302, as illustrated in Figure 25) of the drainage hole channel (302) is connected to (via 304) the water receiving groove bottom surface (the bottom surface of 303, as illustrated in Figure 25), and is connected to (as illustrated in Figure 25) the water receiving groove bottom surface (the bottom surface of 303, as illustrated in Figure 25) in an oblique transition (as 304 is curved, the transition from 302 to 303 via 304 is an oblique transition). Regarding Claim 13, Yan shows (Figures 5, 6, 8, 9, 12, 13, , 14, 16, and 20): An air guide ring assembly (3 and 6) comprising: the water pan (3) according to claim 1 (see rejection of Claim 1 above); an air guide ring (6); and a connection device (connecting structure, Page 5, line 11) comprising a body (body of 34) and a locking portion (61), the body (body of 34) being disposed at (as illustrated in Figure 12) the water pan (3), and an end (the top end of 34, as illustrated in Figure 13) of the body (body of 34) having a connecting hole (the hole in 34, as illustrated in Figure 13), wherein the locking portion (61) is disposed at (as illustrated in Figure 14) the air guide ring (6) and arranged at an end (in the assembled position, 61 is arranged through the end of 34) of the body (body of 34), the locking portion (61) being abutted with (in the assembled position) at least part of a side wall (the side wall defining the opening in 34) of the body (body of 34) in a circumferential direction (the circumference of the hole in 34) of the connection hole (the hole in 381, as illustrated in Figure 11). Regarding Claim 14, Yan shows (Figures 1, 5, 6, 8, 9, 12, 15, 16, and 20): The locking portion (61) is provide with a countersunk hole (the hole in 61, as illustrated in Figure 15) arranged around an end (the top end) of the body (body of 34), the side wall (the side wall defining the opening in 34) of the body (body of 34) being abutted against (in the assembled position) a hole wall (the wall of 61) of the countersunk hole (the hole in 61). Regarding Claim 18, Yan shows (Figures 1, 5, 6, 8, 9, 12, 16, and 20): An indoor unit (100) comprising: the water pan (3) according to Claim 1 (see rejection of Claim 1 above). Allowable Subject Matter Claims 11, 12, 15, 16, 17, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, and 32 are objected to as being dependent on a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Regarding Claim 11, Yan shows the claimed invention except the drainage plug is disposed at a lower end of the drainage hole channel and comprises a covering portion and a blocking portion, the covering portion has a size greater than a size of the blocking portion, the blocking portion being configured to block the drainage hole channel, and the covering portion being located in the countersunk base. Modifying Yan accordingly teaches away from the principle operation of Yan. Claim 12 depends from Claim 11. Regarding Claim 15, Yan shows the claimed invention except the locking portion further has an avoidance hole, the avoidance hole penetrating a bottom wall of the countersunk hole. There is no motivation in the prior art to modify Yan accordingly. Claims 16 and 17 depend from Claim 15. Regarding Claim 19, Yan shows the claimed invention except a baffle assembly disposed at the water pan and comprising a first baffle, a second baffle, a first sealing plate, and a second sealing plate, each of the first sealing plate and the second sealing plate being located between the first baffle and the second baffle, the first sealing plate having an end connected to the first baffle and another end connected to the second baffle, the first sealing plate being connected to the second sealing plate, and a mounting hole being defined between a part of the first sealing plate and a part of the second sealing plate; and a bottom tray, the baffle assembly being mounted at the bottom tray, the bottom tray being located at a side of the baffle assembly facing away from the water pan, one of the first sealing plate and the bottom tray being provided with a catch, another of the first sealing plate and the bottom tray having a catch hole, and the catch being configured to be engaged within the catch hole. Modifying Yan accordingly teaches away from the principle operation of Yan. Claims 20 – 24 depend from Claim 19. Regarding Claim 25, Yan shows (Figures 1, 5, 6, 8, 9, 10, 11, 12, 16, and 20): the water pan (3) comprises a water pan lug (38, 381), and wherein the indoor unit (100) further comprises a casing assembly (casing assembly illustrated in Figure 6), the casing assembly (casing assembly illustrated in Figure 6) comprising: a casing (11) comprising a side plate (the side plate of 11). However, Yan lacks showing the casing assembly further comprises a lifting lug comprising a lifting lug hook and a lifting sub-lug, the lifting sub-lug comprising a water pan connection portion and a side plate connection portion that are sequentially connected, wherein: the lifting lug hook is connected to the water pan connection portion; the side plate is connected to the side plate connection portion; the lifting lug hook and the lifting sub-lug are integrally formed; and the water pan lug is connected to the water pan connection portion. Modifying Yan accordingly teaches away from the principle operation of Yan. Claims 26 – 32 depend from Claim 25.
