[0040] like Figures 1 to 12 As shown, an air conditioner with a fresh air module self-cleaning function includes an air conditioner indoor unit and a water receiving tray 1 and a fresh air module 2 arranged in the air conditioner indoor unit.

[0041] The water receiving pan 1 is used to receive condensed water in the heat exchanger, and includes a water receiving pan body 11 and a baffle assembly arranged on the water receiving pan body 11. The bottom surface of the water receiving pan body 11 is provided with a drainage hole 111, and the baffle assembly is used to open or close the drainage hole 111;

[0042] The fresh air module 2 includes a fresh air shell 21, in which a fresh air cavity 211 is provided, and a threaded guide groove 212 is convexly provided on the inner wall of the fresh air cavity 211. A water inlet 213 and a water outlet 214 are also opened on the inner wall of the fresh air cavity 211. The water inlet 213 is located at the starting end of the threaded guide groove 212, and the water outlet 214 is located at the end of the threaded guide groove 212. The water inlet 213 of the fresh air module 2 and the drainage hole 111 of the water receiving tray 1 are connected through a first drainage pipe 3, and the water outlet 214 of the fresh air module 2 is connected to a second drainage pipe 4.

[0043] The condensed water in the water receiving pan 1 that receives the condensed water of the heat exchanger is introduced into the fresh air chamber 211 of the fresh air module 2, and a threaded guide groove 212 is provided on the inner wall of the fresh air chamber 211, so that the condensed water flows along the threaded guide groove 212 to clean the inner wall of the fresh air module 2, and finally the condensed water is discharged from the water outlet 214 of the fresh air module 2.

[0044] In the utility model, a vertical fixing rib 12 is provided in the water receiving tray body 11, and the fixing rib 12 is circularly arranged around the drainage hole 111, and at least one slot 121 is provided on the fixing rib 12; the baffle assembly includes a motor 13 and a baffle 14, and specifically, the motor 13 is a stepping motor. The motor 13 is fixedly mounted on the upper end of the fixing rib 12, and the driving shaft of the motor 13 is connected to the baffle 14 and can drive the baffle 14 to open or close the slot 121. The driving shaft of the motor 13, the drainage hole 111, and the center of the baffle 14 are on the same axis.

[0045] In the present invention, the motor 13 can be connected to the control module of the air conditioner. When the fresh air module 2 is started, the motor 13 drives the baffle 14 to close the slot 121, and the condensed water no longer enters the fresh air chamber 211, thereby preventing the fresh air filter in the fresh air chamber 211 from absorbing water and getting wet, thereby affecting the fresh air filtering effect. When the fresh air module 2 is closed, the motor 13 drives the baffle 14 to open the slot 121, and use the condensed water to clean the inner wall of the fresh air chamber. Furthermore, when the fresh air module 2 is started, the fresh air startup needs to be delayed to ensure that all the water in the fresh air chamber 211 is discharged.

[0046] More specifically, Figures 9 to 11As shown, when two opposite slots 121 are formed on the fixing rib 12, the baffle 14 includes a first connecting plate 141, a second connecting plate 142 and a third connecting plate 143, the first connecting plate 141 and the third connecting plate 143 are arranged opposite to each other and are respectively located in a slot 121, the upper part of the first connecting plate 141 and the upper part of the third connecting plate 143 are connected through the second connecting plate 142, and the second connecting plate 142 is fixedly connected to the driving shaft of the motor 13; the first connecting plate 141 is provided with a first stop 1411 and a second stop 1412, the first stop 1411 and the second stop 1412 are respectively located on both sides of the first connecting plate 141 and have opposite opening directions, and the first stop The depth of the opening 1411 is greater than that of the second stop 1412; the third connecting plate 143 is provided with a third stop 1431 and a fourth stop 1432, the third stop 1431 and the fourth stop 1432 are respectively located on both sides of the third connecting plate 143 and have opposite opening directions, and the depth of the third stop 1431 is greater than that of the fourth stop 1432; the opening directions of the first stop 1411 and the third stop 1431 are opposite; when the motor 13 drives the baffle 14 to rotate, the first stop 1411 and the third stop 1431 respectively cooperate with the fixing rib 12 to open the slot 121, or the second stop 1412 and the fourth stop 1432 respectively cooperate with the fixing rib 12 to close the slot 121.

[0047] The first connecting plate 141 and the third connecting plate 143 are both arranged in a circular arc shape, and the first stop 1411, the second stop 1412, the third stop 1431 and the fourth stop 1432 are all arranged in a circular arc shape. In this way, when the baffle 14 is rotated, the first stop 1411, the second stop 1412, the third stop 1431 and the fourth stop 1432 can be accurately matched with the fixing rib 12.

[0048] A non-circular driving shaft groove 1421 is formed on the second connecting plate 142 , and the driving shaft of the motor 13 is limitedly disposed in the driving shaft groove 1421 .

[0049] The heights of the first connecting plate 141 and the third connecting plate 143 are not lower than the height of the fixing rib 12. This can prevent condensed water from entering the drainage hole 111 through the gap between the first connecting plate 141 and the water receiving tray body 11 and the gap between the third connecting plate 143 and the water receiving tray body 11 when the slot 121 is closed.

[0050] In order to protect the motor 13 and prevent the motor 13 from being burned by water, the baffle assembly further includes a cover plate 15 , which is fixedly sleeved on the outside of the motor 13 and can completely cover the motor 13 .

[0051] The fresh air housing 21 is also provided with an air outlet 215, and a fresh air valve plate 216 is rotatably provided at the air outlet 215. Figures 5 to 7 As shown, specifically, the rotating shafts on both sides of the fresh air valve plate 216 are clamped in the valve plate positioning groove 2152 at the air outlet 215. The fresh air valve plate 216 is used to control the inflow of fresh air. The lower end of the air outlet 215 is provided with a limit point 2151 for preventing the lower end of the fresh air valve plate 216 from rotating backward, so that when condensed water flows in, the fresh air valve plate 216 will not tilt backward. The side of the fresh air valve plate 216 located in the fresh air cavity 211 is provided with a texture portion 2161 that matches the threaded guide groove 212 on the inner wall of the fresh air cavity 211. Since the fresh air valve plate 216 does not rely on the motor drive, the other side of the fresh air valve plate 216 is provided with a hollow portion 2162. More specifically, the upper hollow area of ​​the hollow portion 2162 of the fresh air valve plate 216 is larger than the lower hollow area, thereby reducing the weight of the fresh air valve plate 216. When the fresh air is turned on, the fresh air valve plate 216 is rotated by air pressure. Since the rotation amount of the fresh air valve plate 216 will not exceed 90°, the fresh air valve plate 216 can be reset by its own gravity.

[0052] All features described in the specification, the attached claims and the drawings, whether alone or in any combination thereof, are important features of the present utility model.

[0053] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "an implementation", "specific implementation", "other implementations", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment, implementation or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.
