Based on the embodiments provided by the present disclosure, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present disclosure.

[0102] This embodiment provides an air - conditioner indoor unit, and the following will refer to Figures 1 - 40 to describe the air - conditioner indoor unit.

[0103] The air - conditioner indoor unit 100 is a component of the air conditioner. Among them, the air conditioner further includes an air - conditioner outdoor unit 200.

[0104] See Figures 1 - 3 , the air conditioner 1000 may include an air - conditioner indoor unit 100 and an air - conditioner outdoor unit 200. The air - conditioner indoor unit 100 is installed in the indoor space. The air - conditioner outdoor unit 200 is installed in the outdoor space for heat exchange with the outdoor environment.

[0105] The air conditioner indoor unit 100 includes a main body which has a bottom and a top. The direction from the bottom to the top of the main body is the height direction of the main body, and the main body also has a length direction, where the length direction of the main body is from one side to the other side in the left - right direction of the main body. The main body has a front side and a rear side which are oppositely arranged. Among them, the side of the main body facing the user is the front side of the main body, and the direction from the front side to the rear side of the main body is the front - rear direction of the main body.

[0106] The main body may include a casing 11 which is arranged in the indoor space. The casing 11 has a front side and a rear side which are oppositely arranged. Among them, the side of the casing 11 facing the user is the front side of the casing 11.

[0107] The main body may include a heat - exchange air inlet 111 which is arranged at the top of the casing 11. When refrigerating or heating, indoor air can enter the interior of the casing 11 through the heat - exchange air inlet 111.

[0108] The main body may include a first chamber which is arranged inside the casing 11. The first chamber is in communication with the heat - exchange air inlet 111, and indoor air can enter the first chamber through the heat - exchange air inlet 111.

[0109] The main body may include a heat - exchange air outlet 112 which is arranged at the bottom of the casing 11. The first chamber is respectively in communication 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.

[0110] The main body may include an indoor heat exchanger 1001 which is arranged in the first chamber. The indoor heat exchanger 1001 is used for heat - exchanging with the indoor air entering the first chamber.

[0111] In some embodiments, the main body may include a heat - exchange fan which 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 increase the air intake into the room.

[0112] The fan may include a motor and a fan. The drive 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.

[0113] In some embodiments, the air conditioner outdoor unit 200 is arranged in the outdoor space. The air conditioner outdoor unit 200 includes a housing. A second chamber is arranged inside the housing. An outdoor air inlet and an outdoor air outlet are arranged on the housing. The outdoor air inlet is in communication with the outdoor space and the second chamber, and the outdoor air outlet is in communication with the outdoor space and the second chamber.

[0114] In some embodiments, an outdoor heat exchanger 202 is disposed inside the housing. A refrigerant flows through the outdoor heat exchanger 202, and the refrigerant in the outdoor heat exchanger 202 can be used to exchange heat with the air that enters the second chamber and flows through the outdoor heat exchanger 202.

[0115] In some embodiments, a compressor 201 is disposed inside the housing. The compressor 201 is provided in the second chamber and is installed at the bottom of the air conditioner outdoor unit 200.

[0116] In some embodiments, the air conditioner outdoor unit 200 may include a throttling device 204. The throttling device 204 is disposed in the second chamber and is used to expand the liquid-phase refrigerant in a high-temperature and high-pressure state into a low-pressure liquid-phase refrigerant. The throttling device 204 may be disposed on the leeward side of the outdoor heat exchanger 202 to facilitate connection to the compressor 201.

[0117] The air conditioner 1000 performs the refrigeration cycle of the air conditioner 1000 by using the compressor 201, the outdoor heat exchanger 202, the throttling device 204, and the indoor heat exchanger 1001. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies the refrigerant to the air that has been conditioned and heat-exchanged.

[0118] The compressor 201 compresses the refrigerant gas in a low-temperature and low-pressure state and discharges the refrigerant gas in a high-temperature and high-pressure state. The discharged refrigerant gas flows into the outdoor heat exchanger 202.

[0119] The outdoor heat exchanger 202 condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0120] The throttling device 204 expands the liquid-phase refrigerant in a high-temperature and high-pressure state that has been condensed in the outdoor heat exchanger 202 into a low-pressure liquid-phase refrigerant.

[0121] The indoor heat exchanger 1001 evaporates the refrigerant that has expanded in the throttling device 204 and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor 201.

[0122] The indoor heat exchanger 1001 can achieve a refrigeration effect by using the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. Throughout the cycle, the air conditioner 1000 can adjust the temperature of the indoor space.

[0123] In both the indoor heat exchanger 1001 and the outdoor heat exchanger 202, one of them is a condenser and the other is an evaporator. When the indoor heat exchanger 1001 is used as a condenser and the outdoor heat exchanger 202 is used as an evaporator, the air conditioner 1000 serves as a heater in the heating mode. When the indoor heat exchanger 1001 is used as an evaporator and the outdoor heat exchanger 202 is used as a condenser, the air conditioner 1000 serves as a cooler in the cooling mode.

[0128] In some embodiments, the filter screen 121 is arranged around the support frame 125 along the length direction of the main body, and the shape of the filter screen 121 can be set as a ring.

[0129] In some embodiments, the cleaning module 12 may include a first driving brush 1207, the first driving brush 1207 is arranged on the outer side of the filter screen 121, and the first driving brush 1207 is used to drive the filter screen 121 to rotate.

[0130] The first driving brush 1207 is in contact with the filter screen 121 so that there is a frictional resistance between the first driving brush 1207 and the filter screen 121. When the first driving brush 1207 rotates, it can drive the filter screen 121 to rotate synchronously through frictional transmission, and the filter screen 121 can move around the support frame 125.

[0131] In some embodiments, the cleaning module 12 may include a first cleaning brush 127, the first cleaning brush 127 is arranged on the outer side of the filter screen 121, the first cleaning brush 127 abuts against the filter screen 121, and the first cleaning brush 127 is used to brush off the dust on the filter screen 121.

[0132] When the filter screen 121 runs driven by the first driving brush 1207, the first cleaning brush 127 can rotate relative to the filter screen 121, and the first cleaning brush 127 can brush off the dust on the filter screen 121, thereby cleaning the filter screen 121.

[0133] In some embodiments, the support frame 125 may include a recessed portion 1252, and the recessed portion 1252 is recessed into the inside of the support frame 125.

[0134] The recessed portion 1252 is adapted to the first driving brush 1207. At least a part of the first driving brush 1207 is disposed in the recessed portion 1252 in a mating manner. At least a part of the filter screen 121 is disposed between the recessed portion 1252 and the first driving brush 1207. The filter screen 121 disposed between the recessed portion 1252 and the first driving brush 1207 is arranged around the periphery of the first driving brush 1207. The first driving brush 1207 abuts against the filter screen 121 to drive the filter screen 121 to rotate.

[0135] 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.

[0136] 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 the first driving roller 12071 can rotate about its rotation axis.

[0137] 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 contact the filter screen 121 and drive the filter screen 121 to rotate.

[0138] 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.

[0139] The first bristles 12072 are uniformly 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. When the first driving brush 1207 and the filter screen 121 are transmitting power, slipping can be avoided, and the transmission efficiency and cleaning efficiency of the filter screen 121 can be improved.

[0140] 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 the first steering column 12081 can rotate relative to the filter screen 121.

[0141] The first steering column 12081 is rotatably connected to the first end of the support frame 125, and the filter screen 121 is disposed around the periphery of the first steering column 12081.

[0142] In some embodiments, the cleaning module 12 may include a second steering column 12082. The second steering column 12082 is disposed inside the filter screen 121, the second steering column 12082 abuts against the filter screen 121, and the second steering column 12082 is rotatable relative to the filter screen 121.

[0143] 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 disposed around the periphery of the second steering column 12082.

[0144] The second steering column 12082 and the first steering column 12081 are respectively disposed 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 to reduce the frictional resistance between the filter screen 121 and the first steering column 12081 and the second steering column 12082, facilitating the rotation of the filter screen 121 and avoiding the slipping of the filter screen 121 relative to the first driving brush 1207 caused by excessive frictional resistance.

[0145] 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 disposed inside the box body 126. At least a part of the filter screen 121 passes through the opening at the side of the box body 126 and is disposed 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.

[0146] In some embodiments, the first cleaning brush 127 may include a second driving roller 1273. The second driving roller 1273 is disposed below the filter screen 121, and the second driving roller 1273 is rotatably connected to the box body 126.

[0147] The second driving roller 1273 is generally cylindrical. 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.

[0148] In some embodiments, the first cleaning brush 127 may include second bristles 1274. The second bristles 1274 are disposed on the surface of the second driving roller 1273, and the second bristles 1274 are in contact with the filter screen 121.

[0149] In some embodiments, the second drive 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.

[0150] The second bristles 1274 are evenly distributed on the surface of the second drive 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.

[0151] 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 arranged 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.

[0152] 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.

[0153] 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.

[0154] In some embodiments, the first comb teeth 12092 and the first base 12091 are integrally formed.

[0155] 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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 dust can fall into the dust collection box 128.

[0160] 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.

[0161] 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.

[0162] 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.

[0163] 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.

[0164] 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.

[0165] 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 meshed with the first driving gear 12002 for transmission. 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.

[0166] In some embodiments, the cleaning module 12 may include a third driving gear 12004, which is axially connected to an end of the first driving brush 1207. The third driving gear 12004 meshes with and is driven by a 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.

[0167] The first driving motor 12001 rotates through a driving output shaft to drive 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.

[0168] 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, and 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.

[0169] 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.

[0170] 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 excessive frictional resistance.

[0171] 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, the raised rib 1253 is connected to the recess 1252, and the raised rib 1253 may be integrally formed with the support frame 125.

[0172] The raised rib 1253 protrudes and extends in the direction close to 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.

[0173] In some embodiments, the cleaning module 12 may include a first air inlet grille 12005, and the first air inlet grille 12005 is connected to the support frame 125. The first air inlet grille 12005 is disposed at the top of the support frame 125, and the first air inlet grille 12005 is detachably connected to the support frame 125.

[0174] The first air inlet grille 12005 is located at 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.

[0175] The connection between the first air inlet grille 12005 and the support frame 125 can be a snap connection.

[0176] The cleaning module 12 may include a second air inlet grille 12006, which is disposed at the bottom of the support frame 125, and the second air inlet grille 12006 is detachably connected to the support frame 125.

[0177] The second air inlet grille 12006 is located at the bottom of the filter screen 121, and the second air inlet grille 12006 can restrict the filter screen 121 to prevent the filter screen 121 from detaching from the support frame 125.

[0178] The connection between the second air inlet grille 12006 and the support frame 125 can be a snap connection.

[0179] 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.

[0180] See Figures 21 - 25 , in some embodiments, the filter screen 121 may include a mesh portion 1211, on which there are mesh holes, indoor air can flow through the mesh holes and flow out from the heat exchange air outlet, and dust can be isolated or adsorbed on the mesh portion 1211 by the filter screen 121.

[0181] 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 into one body at the splicing seam 1212.

[0182] The mesh portion 1211 is melted into one body at the splicing seam 1212, that is, the filter screen 121 at the splicing seam 1212 is melted into one body, 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.

[0183] 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.

[0184] 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, and the first bristles 12072 can penetrate the mesh holes.

[0185] When at least a part of the splicing seam 1212 comes into contact with the first driving brush 1207, at least a part of the mesh portion 1211 comes into contact with the first driving brush 1207. That is, when the splicing seam 1212 rotates to contact the first driving brush 1207, at this time, a part of the mesh portion 1211 also comes into contact with the first driving brush 1207, and a 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.

[0186] In some embodiments, the first driving brush 1207 rotates around 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.

[0187] The extending direction of the splicing seam 1212 is not parallel to the rotation axis of the first driving brush 1207, which can make the contact surface between the first driving brush 1207 and the filter screen 121 intersect 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, a part of the mesh portion 1211 also comes into contact with the first driving brush 1207, so that a 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.

[0188] In some embodiments, at least a part of the shape of the splicing seam 1212 is set to be one of a broken line shape, an arc shape, and a sine wave shape. That is, the splicing seam 1212 can be set to be non-linear, which can make the first driving brush 1207 contact at least a part of the mesh portion 1211 when the splicing seam 1212 contacts the first driving brush 1207, so that a 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.

[0189] In some embodiments, the extending direction of the splicing seam 1212 is inclined relative to the front-back direction of the main body.

[0190] 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.

[0191] 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 part 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. 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, so there is a problem of slipping when the first driving brush 1207 drives the filter screen 121 to move.

[0192] See Figures 26 - 31 , in some embodiments, the support frame 125 may include a raised rib 1253. The raised rib 1253 is arranged corresponding to the first driving brush 1207. The raised rib 1253 protrudes and extends in a direction close to the first driving brush 1207. The raised rib 1253 contacts the filter screen 121 so that there is a first gap 1254 between the filter screen 121 and the support 125.

[0193] 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.

[0194] 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.

[0195] At least part of the filter screen 121 is arranged between the raised rib 1253 and the first driving brush 1207. The raised rib 1253 contacts the filter screen 121 so that there is a first gap 1254 between the filter screen 121 and the support frame 125.

[0196] The first driving roller 12071 rotates to drive the first brush bristles 12072 to rotate, and the rotation of the first brush bristles 12072 drives the filter screen 121 to rotate. When the filter screen 121 contacts the first driving brush 1207, at least part of the first brush bristles 12072 pass through the mesh holes into the first gap 1254, which can increase the frictional force between the first brush bristles 12072 and the filter screen 121 and improve the reliability of the brush bristles driving the filter screen 121 to rotate.

[0197] In some embodiments, in the height direction of the main body, at least part of the first brush bristles 12072 partially overlap with the raised ribs 1253, that is, part of the first brush bristles 12072 pass through the filter screen 121 and partially overlap with the raised ribs 1253 in the height direction of the main body, and part of the first brush bristles 12072 pass through the filter screen 121 and are located in the first gap 1254, which can increase the frictional force between the first brush bristles 12072 and the filter screen 121 and is beneficial to the first driving roller 12071 driving the first brush to rotate and the first brush driving the filter screen 121 to rotate.

[0198] In some embodiments, at least part of the raised ribs 1253 are arranged to extend along the length direction of the main body, and the filter screen 121 surrounds the support frame 125 along the length direction of the main body.

[0199] In some embodiments, the raised ribs 1253 can be arranged to be at least two, and the at least two raised ribs 1253 are arranged at intervals. In the direction of the interval arrangement of the raised ribs 1253, there is a first preset distance e between two adjacent raised ribs 1253, satisfying: 50mm > e > 10mm.

[0200] In some embodiments, the direction of the interval arrangement of the raised ribs 1253 can be the length direction of the rotation axis of the first driving roller 12071, and the raised ribs 1253 can be arranged at intervals along the length direction of the rotation axis of the first driving roller 12071. In this arrangement direction, the first preset distance e satisfies e > 10mm to avoid the distance between two adjacent raised ribs 1253 being too short.

[0201] e ≤ 10mm can make the distance between two adjacent raised ribs 1253 too short, resulting in a relatively large number of raised ribs 1253. Furthermore, it can make the contact area between the filter screen 121 and the raised ribs 1253 too large, resulting in a relatively large frictional force between the filter screen 121 and the raised ribs 1253 and an excessive driving torque of the first driving brush 1207 driving the filter screen 121, reducing the reliability of the first driving brush 1207 driving the filter screen 121.

[0202] In some embodiments, the raised ribs 1253 can be arranged at intervals along the length direction of the rotation axis of the first driving roller 12071. In this arrangement direction, the first preset distance e satisfies e < 50mm to avoid the distance between two adjacent raised ribs 1253 being too long.

[0203] If the distance between two adjacent protruding ribs 1253 is too long, i.e., e≥50mm, the number of protruding ribs 1253 can be reduced, and thus the contact area between the first driving brush 1207 and the protruding ribs 1253 can be reduced, and the contact area between the first driving brush 1207 and the filter screen 121 can also be reduced, which easily causes the problem that the first driving brush 1207 cannot effectively drive the filter screen 121 to rotate and slips.

[0204] In some embodiments, the width of the filter screen 121 is the second preset distance f, and the width direction of the filter screen 121 is set to be the same as the length direction of the rotation axis of the first driving roller 12071, satisfying f>150mm, which can avoid the small width of the filter screen 121, ensure that the filter screen 121 effectively filters the air flowing into the heat exchange air inlet, and ensure the air intake volume and dust filtration efficiency of the heat exchange air inlet.

[0205] If the width of the filter screen 121 is set too small, for example, f≤150mm, the width of the filter screen 121 will be small, and the air flowing into the heat exchange air inlet cannot be effectively filtered by the filter screen 121, reducing the filtration efficiency of dust removal.

[0206] In some embodiments, the width of the filter screen 121 is the second preset distance f, and the width direction of the filter screen 121 is set to be the same as the length direction of the rotation axis of the first driving roller 12071, satisfying f<200mm, which can avoid the large width of the filter screen 121, avoid the filter screen 121 occupying a large space, and then avoid the large size of the main body being set, which can reduce costs and improve aesthetics.

[0207] If the width of the filter screen 121 is large, i.e., f≥200mm, the filter screen 121 can occupy a large space, which will cause the large size of the main body, increase costs and affect aesthetics.

[0208] In some embodiments, the first preset distance e and the second preset distance f satisfy: e / f>0.1, to avoid too many protruding ribs 1253 in contact with the filter screen 121 and avoid the first driving brush 1207 being unable to effectively drive the filter screen 121 to rotate.

[0209] If the number of protruding ribs 1253 is large, i.e., e / f<0.1, the contact area between the filter screen 121 and the protruding ribs 1253 will be large, that is, the interference area between the protruding ribs 1253 and the first driving brush 1207 will be large, which will increase the friction force for the first driving brush 1207 to drive the filter screen 121 to rotate, and increase the rotation torque of the first driving brush 1207 to drive the filter screen 121, which is not conducive to the rotation of the filter screen 121.

[0210] Specifically, the ratio of the first preset distance e to the second preset distance f can be 0.11, 0.15, 0.2 or 0.25, etc.

[0211] In some embodiments, the first preset spacing e and the second preset distance f satisfy: e / f < 0.5, so as to avoid fewer protruding ribs 1253 in contact with the filter screen 121 and prevent the first driving brush 1207 from slipping on the filter screen 121.

[0212] If the number of the protruding ribs 1253 is set to be small, that is, e / f ≥ 0.5, the contact area between the filter screen 121 and the protruding ribs 1253 will be small, which means the interference area between the filter screen 121 and the first driving brush 1207 will be small, and the frictional force for the first driving brush 1207 to drive the filter screen 121 to rotate will be reduced, making the first driving brush 1207 unable to effectively drive the filter screen 121 to rotate and causing the first driving brush 1207 to slip on the filter screen 121.

[0213] Specifically, the ratio of the first preset spacing e to the second preset distance f can be 0.3, 0.33, 0.4, 0.45, 0.49, etc.

[0214] In some embodiments, in the length direction of the main body, at least two protruding ribs 1253 extend with different lengths.

[0215] In some embodiments, at least part of the protruding ribs 1253 are arranged to extend along the length direction of the rotation axis of the first driving roller 12071.

[0216] The protruding ribs 1253 can be set to at least two, and the at least two protruding ribs 1253 are arranged at intervals. The direction of the interval arrangement of the protruding ribs 1253 can be set to the length direction of the main body, which can increase the interference area between the protruding ribs 1253 and the first driving brush 1207 and is beneficial to the first driving brush 1207 to drive the filter screen 121.

[0217] In some embodiments, in the projection in the height direction of the main body, the extending direction of the protruding ribs 1253 is inclined relative to the length direction of the main body, which can cause the protruding ribs 1253 to interfere with the first driving brush 1207 and is beneficial to the first driving brush 1207 to drive the filter screen 121 to rotate.

[0218] See Figures 32 - 40 , in some embodiments, the cleaning module may include a first turning roller 12007. The first turning roller 12007 is arranged inside the filter screen 121, and the first turning roller 12007 is rotatably connected to the support frame.

[0219] In some embodiments, the first turning roller 12007 can be set as a cylindrical roller to reduce the frictional force between the first turning roller 12007 and the filter screen 121.

[0220] In some embodiments, the first turning roller 12007 and the first cleaning brush are located on the same side of the support frame, and the filter screen 121 extends around the bottom of the first turning roller 12007 to between the first driving brush 1207 and the support frame.

[0221] In the projection on a plane perpendicular to the length direction of the main body, the first turning roller 12007 and the first cleaning brush at least partially overlap. When the filter screen 121 extends around the bottom of the first turning roller 12007 to between the first driving brush 1207 and the support frame, that is, when the filter screen 121 extends around the bottom of the first turning roller 12007 to the top of the first driving brush 1207, the contact area between the filter screen 121 and the top of the first driving brush 1207 can be increased, and the friction between the first driving brush 1207 and the filter screen 121 can be increased, thereby improving the driving efficiency of the first driving brush 1207 on the filter screen 121 and preventing the first driving brush 1207 from slipping when driving the filter screen 121.

[0222] See Figures 32 - 40 , in some embodiments, in the height direction of the main body, the bottom of the first turning roller 12007 is lower than the top of the first driving brush 1207, and the filter screen 121 extends upward and obliquely around the bottom of the first turning roller 12007 to between the first driving brush 1207 and the support frame, which can increase the contact area between the filter screen 121 and the top of the first driving brush 1207, increase the friction between the first driving brush 1207 and the filter screen 121, thereby improving the driving efficiency of the first driving brush 1207 on the filter screen 121 and preventing the first driving brush 1207 from slipping when driving the filter screen 121.

[0223] In some embodiments, in the height direction of the main body, the distance between the bottom of the first turning roller 12007 and the top of the first driving brush 1207 is set as the third preset distance g, and the distance between the top and the bottom of the first driving brush 1207 is set as the fourth preset distance h, satisfying g / h < 0.6.

[0224] The top of the first driving brush 1207 is defined as the topmost part of the first bristles 12072 provided at the top of the first driving brush 1207, and the bottom of the first driving brush 1207 is defined as the bottommost part of the first bristles 12072 provided at the bottom of the first driving brush 1207. In the height direction of the main body, the third preset distance g and the fourth preset distance h satisfy a proportional relationship, such as g / h < 0.6, which can reduce the contact area between the filter screen 121 and the first driving brush 1207 and reduce the radian of the contact area between the filter screen 121 and the first driving brush 1207, which is beneficial to reducing the driving resistance between the first driving brush 1207 and the filter screen 121.

[0225] If the ratio of the third preset spacing g to the fourth preset spacing h is too large, for example, g / h ≥ 0.6, that is, if the distance between the bottom of the first turning roller 12007 and the top of the first driving brush 1207 is too large, the contact area between the filter screen 121 and the first driving brush 1207 will be too large, which will excessively increase the friction force between the filter screen 121 and the first driving brush 1207, and then excessively increase the rotational torque of the first driving brush 1207, which is not conducive to the first driving brush 1207 driving the filter screen 121 to rotate.

[0226] Specifically, the ratio between the third preset spacing g and the fourth preset spacing h can be 0.55, 0.5, 0.44 or 0.41.

[0227] In some embodiments, in the height direction of the main body, the distance between the bottom of the first turning roller 12007 and the top of the first driving brush 1207 is set as the third preset spacing g, and the distance between the top of the first driving brush 1207 and the bottom of the first driving brush 1207 is set as the fourth preset spacing h, satisfying g / h > 0.1.

[0228] The top of the first driving brush 1207 is defined as the topmost part of the first bristles 12072 provided at the top of the first driving brush 1207, and the bottom of the first driving brush 1207 is defined as the bottommost part of the first bristles 12072 provided at the bottom of the first driving brush 1207. In the height direction of the main body, the third preset spacing g and the fourth preset spacing h satisfy a proportional relationship, such as g / h > 0.1, which can increase the contact area between the filter screen 121 and the first driving brush 1207 and increase the radian of the contact area between the filter screen 121 and the first driving brush 1207, which is beneficial to improving the driving efficiency of the first driving brush 1207 on the filter screen 121.

[0229] If the ratio of the third preset spacing g to the fourth preset spacing h is too small, for example, g / h ≤ 0.1, that is, if the distance between the bottom of the first turning roller 12007 and the top of the first driving brush 1207 is too small, the contact area between the filter screen 121 and the first driving brush 1207 will be too small, which will excessively reduce the friction force between the filter screen 121 and the first driving brush 1207, and then cause the first driving brush 1207 to slip when driving the filter screen 121, which is not conducive to the first driving brush 1207 driving the filter screen 121 to rotate.

[0230] Specifically, the ratio between the third preset spacing g and the fourth preset spacing h can be 0.11, 0.16, 0.22, 0.3 or 0.4.

[0231] See Figures 35 - 40, in some embodiments, the cleaning module may include a second turning roller 12008. The second turning roller 12008 is disposed inside the filter screen 121. The second turning roller 12008 and the first turning roller 12007 are respectively disposed on opposite sides of the first driving brush 1207. The filter screen 121 extends downwardly between the first driving brush 1207 and the support frame to the bottom of the second turning roller 12008. The bottom of the second turning roller 12008 is in contact with the filter screen 121, which can increase the contact area between the filter screen 121 and the first driving brush 1207 and ensure that the first driving brush 1207 effectively drives the filter screen 121 to rotate.

[0232] In some embodiments, the second turning roller 12008 is rotatably connected to the support frame.

[0233] In some embodiments, the second turning roller 12008 may be configured as a cylindrical roller to reduce the frictional force between the second turning roller 12008 and the filter screen 121.

[0234] In some embodiments, in the height direction of the main body, the distance between the bottom of the second turning roller 12008 and the top of the first driving brush 1207 is set as a fifth preset spacing i, and the distance between the top and the bottom of the first driving brush 1207 is set as a fourth preset spacing h, satisfying i / h > 0.1.

[0235] The top of the first driving brush 1207 is defined as the topmost part of the first bristles 12072 provided at the top of the first driving brush 1207, and the bottom of the first driving brush 1207 is defined as the bottommost part of the first bristles 12072 provided at the bottom of the first driving brush 1207. In the height direction of the main body, the fifth preset spacing i and the fourth preset spacing h satisfy a proportional relationship, such as i / h > 0.1, which can increase the contact area between the filter screen 121 and the first driving brush 1207 and increase the radian of the contact area between the filter screen 121 and the first driving brush 1207, which is beneficial to improving the driving efficiency of the first driving brush 1207 on the filter screen 121.

[0236] If the ratio of the fifth preset spacing i and the fourth preset spacing h is too small, for example, i / h ≤ 0.1, that is, if the distance between the bottom of the second turning roller 12008 and the top of the first driving brush 1207 is too small, the contact area between the filter screen 121 and the first driving brush 1207 will be too small, which will excessively reduce the frictional force between the filter screen 121 and the first driving brush 1207, and further cause the first driving brush 1207 to slip when driving the filter screen 121, which is not conducive to the first driving brush 1207 driving the filter screen 121 to rotate.

[0237] Specifically, the ratio between the fifth preset spacing i and the fourth preset spacing h may be 0.11, 0.16, 0.22, 0.3 or 0.4.

[0238] In some embodiments, in the height direction of the main body, the distance between the bottom of the second turning roller 12008 and the top of the first driving brush 1207 is set as the fifth preset distance i, and the distance between the top and the bottom of the first driving brush 1207 is set as the fourth preset distance h, satisfying i / h < 0.6.

[0239] The top of the first driving brush 1207 is defined as the topmost part of the first bristles 12072 provided at the top of the first driving brush 1207, and the bottom of the first driving brush 1207 is defined as the bottommost part of the first bristles 12072 provided at the bottom of the first driving brush 1207. In the height direction of the main body, the fifth preset distance i and the fourth preset distance h satisfy a proportional relationship, such as i / h < 0.6, which can appropriately reduce the contact area between the filter screen 121 and the first driving brush 1207 and reduce the radian of the contact area between the filter screen 121 and the first driving brush 1207, which is beneficial to reducing the driving resistance between the first driving brush 1207 and the filter screen 121.

[0240] If the ratio of the proportional relationship between the fifth preset distance i and the fourth preset distance h is too large, for example, i / h ≥ 0.6, that is, if the distance between the bottom of the second turning roller 12008 and the top of the first driving brush 1207 is too large, the contact area between the filter screen 121 and the first driving brush 1207 will be too large, which will excessively increase the friction between the filter screen 121 and the first driving brush 1207, and then excessively increase the rotation torque of the first driving brush 1207, which is not conducive to the first driving brush 1207 driving the filter screen 121 to rotate.

[0241] Specifically, the ratio between the fifth preset distance i and the fourth preset distance h can be 0.55, 0.5, 0.44 or 0.41.

[0242] See Figures 38 - 40 , in some embodiments, the cleaning module may include a third turning roller 12009. The third turning roller 12009 is arranged outside the filter screen 121. The third turning roller 12009 and the second turning roller 12008 are arranged on the same side of the first driving brush 1207. The filter screen 121 extends obliquely upward from the bottom of the second turning roller 12008 to the top of the third turning roller 12009. The top of the third turning roller 12009 is in contact with the filter screen 121. The third turning roller 12009 is rotatable to reduce the friction between the filter screen 121 and the third turning roller 12009 and reduce the transmission resistance of the filter screen 121.

[0243] In some embodiments, the third turning roller 12009 is rotatably connected to the support frame.

[0244] In some embodiments, the third turning roller 12009 may be configured as a cylindrical roller to reduce the frictional force between the third turning roller 12009 and the filter screen 121.

[0245] In some embodiments, a line connecting the bottom of the second turning roller 12008 and the top of the third turning roller 12009 is defined as the third connecting line, and the angle between the third connecting line and the horizontal plane is set as the second angle j. The opening of the second angle j faces the third turning roller 12009, and the second angle j > 0°.

[0246] In the height direction of the main body, at least a part of the third turning roller 12009 is arranged above the second turning roller 12008.

[0247] The bottom of the second turning roller 12008 is the lowest point of the second turning roller 12008 in the height direction of the main body, and the top of the third turning roller 12009 is the highest point of the third turning roller 12009 in the height direction of the main body. The second angle j > 0° can make the filter screen 121 contact with the third driving roller, and the third driving roller rotates to reduce the frictional force during the transmission of the filter screen 121 and improve the rotation efficiency of the filter screen 121.

[0248] Specifically, the value of the second angle j can be 5°, 14°, 22° or 25°.

[0249] In some embodiments, a line connecting the bottom of the second turning roller 12008 and the top of the third turning roller 12009 is defined as the third connecting line, and the angle between the third connecting line and the horizontal plane is set as the second angle j. The opening of the second angle j faces the third turning roller 12009, and the second angle j < 45°.

[0250] The bottom of the second turning roller 12008 is the lowest point of the second turning roller 12008 in the height direction of the main body, and the top of the third turning roller 12009 is the highest point of the third turning roller 12009 in the height direction of the main body. The second angle j < 45° can make the tangent line when the filter screen 121 contacts the third driving roller not too steep, appropriately reduce the acting force of the filter screen 121 on the third driving roller, and further reduce the frictional force between the filter screen 121 and the third driving roller, thus improving the rotation efficiency of the filter screen 121.

[0251] If the second angle is too large, that is, the second angle j ≥ 45°, the tangent line when the filter screen 121 contacts the third driving roller will be too steep, increasing the acting force of the filter screen 121 on the third driving roller, and further increasing the frictional force between the filter screen 121 and the third driving roller, which will increase the resistance to the rotation of the filter screen 121 and affect the rotation efficiency of the filter screen 121.

[0252] In some embodiments, the contact surface between the filter screen 121 and the first driving brush 1207 is an arc surface, and the radian θ of the contact surface satisfies: θ < 200°. When θ is less than 200°, it can ensure that the contact surface between the filter screen 121 and the first driving brush 1207 is not too large, so that the friction between the first driving brush 1207 and the filter screen 121 is moderate, the rotational torque of the first driving brush 1207 can be reduced, the first driving brush 1207 can effectively drive the filter screen 121 to rotate, the rotation efficiency of the filter screen 121 can be improved, and thus the cleaning efficiency of the first cleaning brush for the filter screen 121 can be improved.

[0253] If the value of θ is too large, that is, θ > 200°, the area of the contact surface between the filter screen 121 and the first driving brush 1207 will be increased too much, so that the friction between the filter screen 121 and the first driving brush 1207 is relatively large, and then the rotational torque of the first driving brush 1207 is increased, which is not conducive to the first driving brush 1207 driving the filter screen 121 to rotate, and thus affects the cleaning efficiency of the filter screen 121.

[0254] Specifically, the value of θ can be 199°, 186°, 167°, 150° or 143°.

[0255] In some embodiments, the contact surface between the filter screen 121 and the first driving brush 1207 is an arc surface, and the radian θ of the contact surface satisfies: θ > 90°. When θ is greater than 90°, it can ensure that the contact surface between the filter screen 121 and the first driving brush 1207 is not too small, so that the friction between the first driving brush 1207 and the filter screen 121 is moderate, and it can prevent the first driving brush 1207 from slipping when driving the filter screen 121, the first driving brush 1207 can effectively drive the filter screen 121 to rotate, the rotation efficiency of the filter screen 121 can be improved, and thus the cleaning efficiency of the first cleaning brush for the filter screen 121 can be improved.

[0256] If the value of θ is too small, that is, θ < 90°, the area of the contact surface between the filter screen 121 and the first driving brush 1207 will be reduced too much, so that the friction between the filter screen 121 and the first driving brush 1207 is relatively small, and the first driving brush 1207 will slip when driving the filter screen 121 to move, which is not conducive to the first driving brush 1207 driving the filter screen 121 to rotate, and thus affects the cleaning efficiency of the filter screen 121.

[0257] Specifically, the value of θ can be 91°, 100°, 106°, 125° or 133°.
