The first chamber is respectively communicated with the heat exchange air inlet 111 and the heat exchange air outlet 112. When refrigerating or heating, indoor air flows into the first chamber through the heat exchange air inlet 111 and then flows into the room through the heat exchange air outlet 112.

[0117] The main body may include an indoor heat exchanger 1001, and the indoor heat exchanger 1001 is arranged in the first chamber. The indoor heat exchanger 1001 is used for heat exchange with the indoor air entering the first chamber.

[0118] In some embodiments, the main body may include a heat exchange fan, and the heat exchange fan is arranged in the first chamber. The fan can be used to drive indoor air to enter the first chamber through the heat exchange air inlet 111, then flow through the indoor heat exchanger 1001, and then flow into the room through the heat exchange air outlet 112. It can be set that the fan is arranged on the leeward side of the indoor heat exchanger 1001 to reduce the resistance of the indoor heat exchanger 1001 to air flow and improve the air intake volume into the room.

[0119] The fan may include a motor and a fan. The driving shaft of the motor is connected to the fan, and the motor drives the fan to rotate to drive the air flow in the first chamber.

[0142] At least a part of the filter screen 121 is disposed between the recessed portion 1252 and the first driving brush 1207. The first driving brush 1207 abuts against the filter screen 121, which can increase the contact area between the first driving brush 1207 and the filter screen 121, thereby increasing the frictional resistance between the first driving brush 1207 and the filter screen 121. When the first driving brush 1207 rotates, it can prevent slipping between the first driving brush 1207 and the filter screen 121 and prevent affecting the transmission and cleaning effects of the filter screen 121.

[0143] In some embodiments, the first driving brush 1207 may include a first driving roller 12071. At least a part of the first driving roller 12071 is disposed in the recessed portion 1252. The first driving roller 12071 is generally cylindrical in shape and can rotate about its rotation axis.

[0144] See Figures 6 - 14 , in some embodiments, the first driving brush 1207 may include first bristles 12072. The first bristles 12072 are disposed on the surface of the first driving roller 12071. The first bristles 12072 are in contact with the filter screen 121 and drive the filter screen 121 to rotate.

[0145] In some embodiments, the first driving roller 12071 rotates to drive the first bristles 12072 to rotate, and the first bristles 12072 can drive the filter screen 121 to rotate.

[0146] The first bristles 12072 are evenly distributed on the surface of the first driving roller 12071. The first bristles 12072 can penetrate the filter screen 121 to increase the frictional resistance between the first bristles 12072 and the filter screen 121, that is, increase the frictional resistance between the first driving brush 1207 and the filter screen 121, and can avoid slipping during the transmission between the first driving brush 1207 and the filter screen 121, and can improve the transmission efficiency and cleaning efficiency of the filter screen 121.

[0147] In some embodiments, the cleaning module 12 may include a first steering column 12081. The first steering column 12081 is disposed inside the filter screen 121. The first steering column 12081 abuts against the filter screen 121 and can rotate relative to the filter screen 121.

[0148] The first steering column 12081 is rotatably connected to the first end of the support frame 125, and the filter screen 121 is arranged around the periphery of the first steering column 12081.

[0149] In some embodiments, the cleaning module 12 may include a second steering column 12082. The second steering column 12082 is arranged inside the filter screen 121, abuts against the filter screen 121, and is rotatable relative to the filter screen 121.

[0150] The second steering column 12082 is rotatably connected to the second end of the support frame 125. The first end and the second end of the support frame 125 are respectively opposite ends of the support frame 125, and the filter screen 121 is arranged around the periphery of the second steering column 12082.

[0151] The second steering column 12082 and the first steering column 12081 are respectively arranged at opposite ends of the support frame 125 to support the filter screen 121. When the first driving brush 1207 drives the filter screen 121 to rotate, the first steering column 12081 and the second steering column 12082 rotate relative to the support frame 125, so as to reduce the frictional resistance between the filter screen 121 and the first steering column 12081 and the second steering column 12082, facilitate the rotation of the filter screen 121, and avoid the filter screen 121 slipping relative to the first driving brush 1207 due to excessive frictional resistance.

[0152] In some embodiments, the cleaning module 12 may further include a box body 126. Openings may be provided at the bottom and side of the box body 126. The first driving brush 1207 and the first cleaning brush 127 are arranged inside the box body 126. At least part of the filter screen 121 passes through the opening at the side of the box body 126 to be arranged inside the box body 126. The first driving brush 1207 and the first cleaning brush 127 are respectively rotatably connected to the box body 126, and the box body 126 plays a role in supporting and connecting the first driving brush 1207 and the first cleaning brush 127.

[0153] In some embodiments, the first cleaning brush 127 may include a second driving roller 1273. The second driving roller 1273 is arranged below the filter screen 121 and is rotatably connected to the box body 126.

[0154] The second driving roller 1273 is generally arranged in a cylindrical shape. The two axial ends of the second driving roller 1273 are respectively rotatably connected to the box body 126, and the second driving roller 1273 can rotate around its axis.

[0155] In some embodiments, the first cleaning brush 127 may include second bristles 1274. The second bristles 1274 are arranged on the surface of the second driving roller 1273 and are in contact with the filter screen 121.

[0156] In some embodiments, the second driving roller 1273 rotates to drive the second bristles 1274 to rotate, and the second bristles 1274 can contact the filter screen 121 and move relative to the filter screen 121.

[0157] The second bristles 1274 are evenly distributed on the surface of the second driving roller 1273, and the first cleaning brush 127 can rotate in the direction opposite to the movement direction of the filter screen 121, thereby improving the cleaning effect of the first cleaning brush 127 on the filter screen 121.

[0158] See Figure 15 , in some embodiments, the cleaning module 12 may include a second cleaning comb 1209. The second cleaning comb 1209 is disposed in the box body 126 and can be fixedly connected to the box body 126. The first cleaning brush 127 and the second cleaning comb 1209 are disposed on the same side in the length direction of the filter screen 121 so that the second cleaning comb 1209 can contact the first cleaning brush 127. The second cleaning comb 1209 can contact the first cleaning brush 127 to clean the dust on the first cleaning brush 127.

[0159] In some embodiments, the second cleaning comb 1209 may include a first base 12091. The first base 12091 is disposed in the box body 126 and is fixedly connected to the box body 126 to prevent the first base 12091 from rotating under force. The material of the first base 12091 can be plastic and is made by an injection molding process.

[0160] In some embodiments, the second cleaning comb 1209 may include first comb teeth 12092, and the first comb teeth 12092 are connected to the first base 12091.

[0161] In some embodiments, the first comb teeth 12092 and the first base 12091 are integrally formed.

[0162] In some embodiments, the material of the first comb teeth 12092 can be plastic, and the first comb teeth 12092 and the first base 12091 are integrally injection molded by an injection molding process.

[0163] The second comb teeth may include a plurality of comb teeth, and the plurality of comb teeth are arranged along the length direction of the first base 12091.

[0164] When the first cleaning brush 127 rotates, the second cleaning comb 1209 does not rotate. In the rotating state of the first cleaning brush 127, the first comb teeth 12092 intersect and contact the second bristles 1274 to brush off the dust on the second bristles 1274.

[0165] See Figure 5, in some embodiments, a dust collection box 128 is provided in the box body 126. The dust collection box is located below the first cleaning brush 127 so that the dust brushed off by the first cleaning brush 127 can fall into the dust collection box 128.

[0166] The top of the dust collection box 128 is provided with an opening, and the dust collection box 128 is connected to the bottom of the box body 126 through the opening so that the dust can fall into the dust collection box 128.

[0167] The dust collection box 128 can be taken out by pulling, which is convenient for the user to pull out the dust collection box 128 and clean the dust in the dust collection box 128.

[0168] In some embodiments, the first cleaning brush 127 is arranged on the side of the first driving brush 1207 away from the heat exchange air inlet so as to brush off the dust on the filter screen 121 at the end close to the air conditioner indoor unit. By arranging the dust collection box 128 at the end of the air conditioner indoor unit, the space occupied inside the air conditioner indoor unit can be saved, the space utilization rate can be improved, and further the size of the air conditioner indoor unit in the length direction can be reduced, making the air conditioner indoor unit smaller and more beautiful.

[0169] See Figures 6 - 19 , in some embodiments, the cleaning module 12 may include a first driving motor 12001, and the first driving motor 12001 is fixedly connected to the box body 126. The first driving motor 12001 is provided with an output shaft, and the first driving motor 12001 can drive its output shaft to rotate.

[0170] In some embodiments, the cleaning module 12 may include a first driving gear 12002, and the first driving gear 12002 is connected to the output shaft of the first driving motor 12001.

[0171] The axis of the first driving gear 12002 is fixedly connected to the output shaft of the first driving motor 12001, and the first driving motor 12001 can drive its output shaft to drive the first driving gear 12002 to rotate synchronously.

[0172] In some embodiments, the cleaning module 12 may include a second driving gear 12003. The second driving gear 12003 is connected to the axial end of the first cleaning brush 127. The second driving gear 12003 is in meshing transmission with the first driving gear 12002. When the first driving gear 12002 rotates, it drives the second driving gear 12003 to rotate, and the second driving gear 12003 drives the first cleaning brush 127 to rotate synchronously.

[0173] In some embodiments, the cleaning module 12 may include a third driving gear 12004. The third driving gear 12004 is connected to the axial end of the first driving brush 1207. The third driving gear 12004 meshes with and drives the second driving gear 12003. When the second driving gear 12003 rotates, it drives the third driving gear 12004 to rotate, and the rotation of the third driving gear 12004 drives the first driving brush 1207 to rotate synchronously.

[0174] The first driving motor 12001 drives the driving output shaft to rotate, thereby driving the first driving gear 12002 to rotate synchronously. The first driving gear 12002 drives the second driving gear 12003 and the first cleaning brush 127 to rotate. The second driving gear 12003 drives the third driving gear 12004 and the first driving brush 1207 to rotate. The first driving brush 1207 drives the filter screen 121 to move through frictional resistance.

[0175] The first driving brush 1207 rotates clockwise. Through frictional resistance, the first driving brush 1207 drives the filter screen 121 to rotate counterclockwise around the support frame 125, so that the filter screen 121 is rotated to contact the first cleaning brush 127 to clean the filter screen 121. The first cleaning brush 127 rotates counterclockwise. The rotation direction of the first cleaning brush 127 is opposite to the rotation direction of the filter screen 121, which can increase the frictional resistance between the first cleaning brush 127 and the filter screen 121, thereby improving the cleaning effect of the first cleaning brush on the filter screen 121.

[0176] See Figure 20 In some embodiments, the recess 1252 is located on one side in the length direction of the heat exchange air inlet. In the length direction of the heat exchange air inlet, the point on the recess closest to the heat exchange air inlet is defined as the first end point b, and the point on the recess 1252 farthest from the heat exchange air inlet is defined as the second end point c.

[0177] Define the line connecting the axis O of the first driving brush 1207 and the first end point b as the first connecting line, define the line connecting the axis O of the first driving brush 1207 and the second end point c as the second connecting line, and define the angle between the first connecting line and the second connecting line as the first angle a. The opening of the first angle a faces the recess 1252, and the first angle a is greater than or equal to 90° and less than or equal to 180°. When the first angle a is greater than or equal to 90°, the first angle a can be prevented from being too small, so that the contact area between the filter screen 121 and the first driving brush 1207 in the recess 1252 is not too small, which is beneficial to increasing the frictional resistance between the first driving brush 1207 and the filter screen 121 and preventing the first driving brush 1207 from slipping when driving the filter screen 121 to move. When the first angle a is less than or equal to 180°, the first angle a can be prevented from being too large, so that the contact area between the filter screen 121 and the first driving brush 1207 in the groove is not too large, and further the frictional resistance between the filter screen 121 and the first driving brush 1207 in the groove is not too large, which can avoid the problem that the first driving brush 1207 cannot rotate due to too large frictional resistance.

[0178] See Figures 6 - 19 , in some embodiments, the support frame 125 may include a raised rib 1253. The raised rib 1253 is disposed in the recess 1252, and the raised rib 1253 is connected to the recess 1252. The raised rib 1253 may be integrally formed with the support frame 125.

[0179] The raised rib 1253 protrudes and extends towards the first driving brush 1207, and the raised rib 1253 contacts the filter screen 121 so that there is a gap between the filter screen 121 and the recess 1252. The gap between the filter screen 121 and the recess 1252 enables the first bristles 12072 on the first driving brush 1207 to easily penetrate the filter screen 121, and at least part of the first bristles 12072 can penetrate into the gap between the filter screen 121 and the recess 1252, which is convenient for increasing the frictional resistance between the filter screen 121 and the first bristles 12072, beneficial to the first driving brush 1207 driving the filter screen 121 to rotate, and improving the cleaning efficiency and transmission reliability of the filter screen 121.

[0180] In some embodiments, the cleaning module 12 may include a first air inlet grille 12005. The first air inlet grille 12005 is connected to the support frame 125. The first air inlet grille 12005 is disposed on the top of the support frame 125, and the first air inlet grille 12005 is detachably connected to the support frame 125.

[0181] The first air inlet grille 12005 is located on the top of the filter screen 121, and the first air inlet grille 12005 can restrict the filter screen 121 to prevent the filter screen 121 from detaching from the support frame 125.

[0182] The connection mode between the first air inlet grille 12005 and the support frame 125 can be snap connection.

[0183] The cleaning module 12 may include a second air inlet grille 12006. The second air inlet grille 12006 is arranged at the bottom of the support frame 125, and the second air inlet grille 12006 is detachably connected to the support frame 125.

[0184] The second air inlet grille 12006 is located at the bottom of the filter screen 121. The second air inlet grille 12006 can limit the filter screen 121 to prevent the filter screen 121 from detaching from the support frame 125.

[0185] The connection mode between the second air inlet grille 12006 and the support frame 125 can be snap connection.

[0186] The filter screen 121 is restricted between the first air inlet grille 12005 and the second air inlet grille 12006, which can prevent the filter screen 121 from falling.

[0187] See Figures 21 - 25 , in some embodiments, the filter screen 121 may include a mesh portion 1211. There are mesh holes on the mesh portion 1211. Indoor air can flow through the mesh holes and flow out from the heat exchange air outlet. Dust can be isolated or adsorbed on the mesh portion 1211 by the filter screen 121.

[0188] In some embodiments, the filter screen 121 may include a splicing seam 1212. The splicing seam 1212 is connected to the mesh portion 1211, and the mesh portion 1211 is melted together at the splicing seam 1212.

[0189] The mesh portion 1211 is melted together at the splicing seam 1212, that is, the filter screen 121 at the splicing seam 1212 is melted together, and the mesh holes at the splicing seam 1212 are melted and eliminated. When the splicing seam 1212 rotates to contact the first driving brush 1207, the first bristles 12072 cannot pass through the splicing seam 1212, so that the frictional resistance between the splicing seam 1212 and the first bristles 12072 is small at this time, and there is a problem of transmission slip between the first driving brush 1207 and the filter screen 121, and the first driving brush 1207 cannot effectively drive the filter screen 121 to rotate.

[0190] In some embodiments, the first driving brush 1207 may include a first driving roller 12071, and the first driving roller 12071 can rotate around the rotation axis of the first driving roller 12071.

[0191] In some embodiments, the first driving brush 1207 may include first bristles 12072. The first bristles 12072 are arranged on the surface of the first driving roller 12071, and the first bristles 12072 can penetrate the mesh holes.

[0192] When at least part of the splicing seam 1212 contacts the first driving brush 1207, at least part of the mesh portion 1211 contacts the first driving brush 1207. That is, when the splicing seam 1212 rotates to contact the first driving brush 1207, at this time, part of the mesh portion 1211 also contacts the first driving brush 1207, and part of the first bristles 12072 of the first driving brush 1207 can pass through the mesh holes of the mesh portion 1211. The first driving roller 12071 rotates to drive the first bristles 12072 to rotate. When the first bristles 12072 drive the filter screen 121 to rotate and the first driving brush 1207 contacts the filter screen 121 and drives the filter screen 121 to rotate through frictional resistance, the first bristles 12072 passing through the mesh holes can increase the driving force of the first driving brush 1207 on the filter screen 121, improve the transmission efficiency of the filter screen 121, and thus improve the cleaning efficiency of the first cleaning brush 127 on the filter screen 121.

[0193] In some embodiments, the first driving brush 1207 rotates about its rotation axis. In the direction of the rotation axis of the first driving brush 1207, the contact portion between the first driving brush 1207 and the filter screen 121 is linear.

[0194] At least part of the extending direction of the splicing seam 1212 is not parallel to the rotation axis of the first driving brush 1207, which can cause the contact surface between the first driving brush 1207 and the filter screen 121 to be staggered with the splicing seam 1212 when the first driving brush 1207 contacts the splicing seam 1212. When the splicing seam 1212 rotates to contact the first driving brush 1207, part of the mesh portion 1211 also contacts the first driving brush 1207, so that part of the first bristles 12072 of the first driving brush 1207 can pass through the mesh holes of the mesh portion 1211. When the first driving brush 1207 contacts the filter screen 121 and drives the filter screen 121 to rotate through frictional resistance, the first bristles 12072 passing through the mesh holes can increase the driving force of the first driving brush 1207 on the filter screen 121, improve the transmission efficiency of the filter screen 121, and thus improve the cleaning efficiency of the first cleaning brush 127 on the filter screen 121.

[0195] In some embodiments, at least part of the shape of the splicing seam 1212 is set to one of a polygonal line shape, an arc shape, and a sine wave shape, that is, the splicing seam 1212 can be set to a non-linear shape, which can cause the first driving brush 1207 to contact at least part of the mesh portion 1211 when the splicing seam 1212 contacts the first driving brush 1207, so that part of the first bristles 12072 of the first driving brush 1207 can pass through the mesh holes of the mesh portion 1211. When the first driving brush 1207 contacts the filter screen 121 and drives the filter screen 121 to rotate through frictional resistance, the first bristles 12072 passing through the mesh holes can increase the driving force of the first driving brush 1207 on the filter screen 121, improve the transmission efficiency of the filter screen 121, and thus improve the cleaning efficiency of the first cleaning brush 127 on the filter screen 121.

[0196] In some embodiments, at least a portion of the extending direction of the splicing seam 1212 is inclined with respect to the front-rear direction of the main body.

[0197] In some embodiments, the width direction of the splicing seam 1212 is arranged in the same direction as the length direction of the main body. The value range of the width d of the splicing seam 1212 can be any value between 3 mm and 6 mm. The width d of the splicing seam 1212 can be set to 3 mm. When the width d of the splicing seam 1212 is greater than or equal to 3 mm, the width of the splicing seam 1212 can be prevented from being too small, the connection strength of the melted and connected mesh part 1211 can be made higher, and the splicing seam 1212 after melting can be prevented from breaking due to low connection strength.

[0198] If the width d of the splicing seam 1212 is less than 3 mm, the width of the splicing seam 1212 can be made too small, the connection strength of the melted and connected mesh part 1211 can be affected, and the splicing seam 1212 after melting is likely to break due to low connection strength.

[0199] The width d of the splicing seam 1212 can be set to 6 mm. When the width d of the splicing seam 1212 is less than or equal to 6 mm, the width d of the splicing seam 1212 can be prevented from being too large. When the first driving brush 1207 contacts the splicing seam 1212, at least a portion of the first bristles 12072 can contact the mesh part 1211, so that the first bristles 12072 can pass through the mesh holes, thereby increasing the frictional resistance, being beneficial to the transmission efficiency of the filter screen 121, and preventing slipping.

[0200] When the width of the splicing seam 1212 is greater than 6 mm, it cannot be ensured that when the first driving brush 1207 contacts the splicing seam 1212, the first driving brush 1207 can also contact the mesh part 1211 at the same time. Therefore, there is a problem of slipping when the first driving brush 1207 drives the filter screen 121 to move.
