Detailed implementation manners

[0102] The following will clearly and completely describe some embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by those of ordinary skill in the art shall fall within the protection scope of the present disclosure.

[0103] This embodiment provides an indoor unit of an air conditioner. The following will describe the indoor unit of the air conditioner with reference to Figures 1 - 31 for description.

[0104] The indoor unit 100 of the air conditioner is a component of the air conditioner. Among them, the air conditioner further includes an outdoor unit 200 of the air conditioner.

[0105] See Figures 1 - 3 , the air conditioner 1000 may include an indoor unit 100 of the air conditioner and an outdoor unit 200 of the air conditioner. The indoor unit 100 of the air conditioner is installed in the indoor space. The outdoor unit 200 of the air conditioner is installed in the outdoor space for heat exchange with the outdoor environment.

[0106] The indoor unit 100 of the air conditioner includes a main body. The main body 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. The main body also has a length direction. Among them, the direction from one side to the other side of the main body in the left-right direction is the length direction of the main body. The main body has a front side and a rear side that are oppositely arranged. The direction from the front side to the rear side of the main body is the thickness direction of the main body. Among them, the side of the main body facing the user is the front side of the main body. The direction from the front side to the rear side of the main body is the front-rear direction of the main body.

[0107] The main body may include a housing 11. The housing 11 is arranged in the indoor space. The housing 11 has a front side and a rear side that are oppositely arranged. Among them, the side of the housing 11 facing the user is the front side of the housing 11.

[0108] The main body may include a heat exchange air inlet 111. The heat exchange air inlet 111 is arranged at the top of the housing 11. When cooling or heating, indoor air can enter the interior of the housing 11 through the heat exchange air inlet 111.

[0109] The main body may include a first chamber. The first chamber is arranged inside the housing 11. The first chamber is communicated with the heat exchange air inlet 111. Indoor air can enter the first chamber through the heat exchange air inlet 111.

[0110] The main body may include a heat exchange air outlet 112. The heat exchange air outlet 112 is arranged at the bottom of the housing 11. The first chamber is respectively communicated with the heat exchange air inlet 111 and the heat exchange air outlet 112. When cooling or heating, indoor air flows into the first chamber through the heat exchange air inlet 111 and flows into the room through the heat exchange air outlet 112.

[0111] The main body may include an indoor heat exchanger 1001, which is disposed in the first cavity and is used for heat exchange with the indoor air entering the first cavity.

[0112] In some embodiments, the main body may include a heat exchange fan, which is disposed in the first cavity. The fan can be used to drive the indoor air to enter the first cavity through the heat exchange air inlet 111, then flow through the indoor heat exchanger 1001, and flow out to the room through the heat exchange air outlet 112. It can be set that the fan is disposed 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.

[0113] 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 cavity.

[0114] In some embodiments, the air conditioner outdoor unit 200 is disposed in the outdoor space. The air conditioner outdoor unit 200 includes a housing, and a second cavity is disposed inside the housing. The housing is provided with an outdoor air inlet and an outdoor air outlet. The outdoor air inlet is communicated with the outdoor space and the second cavity, and the outdoor air outlet is communicated with the outdoor space and the second cavity.

[0115] 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 for heat exchange with the air entering the second cavity and flowing through the outdoor heat exchanger 202.

[0116] In some embodiments, a compressor 201 is disposed inside the housing. The compressor 201 is disposed in the second cavity and is installed at the bottom of the air conditioner outdoor unit 200.

[0117] In some embodiments, the air conditioner outdoor unit 200 may include a throttling device 204, which is disposed in the second cavity and is used to expand the liquid refrigerant in a high-temperature and high-pressure state into a low-pressure liquid refrigerant. The throttling device 204 can be disposed on the leeward side of the outdoor heat exchanger 202, which is convenient for connection with the compressor 201.

[0118] 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.

[0119] 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.

[0120] The outdoor heat exchanger 202 condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0121] The throttling device 204 expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the outdoor heat exchanger 202 into a low-pressure liquid-phase refrigerant.

[0122] The indoor heat exchanger 1001 evaporates the refrigerant expanded in the throttling device 204 and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor 201.

[0123] The indoor heat exchanger 1001 can achieve a refrigeration effect by using the latent heat of vaporization of the refrigerant to exchange heat with the material to be cooled. During the entire cycle, the air conditioner 1000 can adjust the temperature of the indoor space.

[0124] In both the indoor heat exchanger 1001 and the outdoor heat exchanger 202, one 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.

[0125] Reference Figures 3 - 10 , in some embodiments, the main body may further include a cleaning module 12, the cleaning module 12 is arranged corresponding to the heat exchange air inlet 111, and the cleaning module 12 is used to clean the dust on the filter screen 121.

[0126] In some embodiments, the cleaning module 12 may include a support frame 125, and the support frame 125 is arranged corresponding to the heat exchange air inlet.

[0127] The part of the support frame 125 corresponding to the heat exchange air inlet 111 is provided with a hollow structure so that the indoor air can pass through the support frame 125 through the heat exchange air inlet 111 and flow to the heat exchange air outlet 112.

[0128] In some embodiments, the cleaning module 12 may include a filter screen 121, the filter screen 121 is arranged corresponding to the heat exchange air inlet 111, and air can flow through the heat exchange air inlet 111, the filter screen 121 and the support frame 125 and flow out through the heat exchange air outlet 112.

[0130] 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.

[0131] 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.

[0132] In some embodiments, the cleaning module 12 may include a first cleaning brush 127. The first cleaning brush 127 is disposed outside the filter screen 121, and the first cleaning brush 127 abuts against the filter screen 121.

The first driving roller 12071 is generally cylindrical in shape, and the first driving roller 12071 can rotate about its rotation axis.

[0138] 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.

[0139] In some embodiments, the first driving roller 12071 rotates to drive the first brush bristles 12072 to rotate, and the first brush bristles 12072 can drive the filter screen 121 to rotate.

[0140] The first brush bristles 12072 are evenly distributed on the surface of the first driving roller 12071. The first brush bristles 12072 can penetrate the filter screen 121 to increase the frictional resistance between the first brush bristles 12072 and the filter screen 121, that is, increase the frictional resistance between the first driving brush 1207 and the filter screen 121, which can prevent slipping between the first driving brush 1207 and the filter screen 121 during transmission, and can improve the transmission efficiency and cleaning efficiency of the filter screen 121.

[0141] 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.

[0142] 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.

[0143] 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 can rotate relative to the filter screen 121.

[0144] 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.

[0145] 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, which can facilitate the rotation of the filter screen 121 and prevent the filter screen 121 from slipping relative to the first driving brush 1207 due to excessive frictional resistance.

[0146] 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 on the side of the box body 126 to be 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.

[0147] 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.

[0148] The second driving roller 1273 is generally cylindrical in 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.

[0149] 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.

[0150] In some embodiments, the second driving roller 1273 rotates to drive the second bristles 1274 to rotate. The second bristles 1274 can contact the filter screen 121 and move relative to the filter screen 121.

[0151] The second bristles 1274 are uniformly distributed on the surface of the second driving roller 1273. The first cleaning brush 127 can rotate in the opposite direction to the moving direction of the filter screen 121, thereby improving the cleaning effect of the first cleaning brush 127 on the filter screen 121.

[0152] See Figure 15 , in some embodiments, the cleaning module 12 may include a second cleaning comb 1209. The second cleaning comb 1209 is disposed inside the box body 126, and the second cleaning comb 1209 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 as to facilitate the contact between the second cleaning comb 1209 and 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.

[0153] In some embodiments, the second cleaning comb 1209 may include a first base 12091. The first base 12091 is disposed inside the box body 126, and the first base 12091 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 may be plastic and is made by an injection molding process.

[0154] In some embodiments, the second cleaning comb 1209 may include first comb teeth 12092, and the first comb teeth 12092 are connected to a first base 12091.

[0155] In some embodiments, the first comb teeth 12092 and the first base 12091 are integrally formed.

[0156] In some embodiments, the material of the first comb teeth 12092 may be plastic, and the first comb teeth 12092 and the first base 12091 are integrally injection-molded by an injection molding process.

[0157] The second comb teeth may include a plurality of comb teeth, and the plurality of comb teeth are arranged to extend along the length direction of the first base 12091.

[0158] 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.

[0159] 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.

[0160] The top of the dust collection box 128 is provided with an opening, and the dust collection box 128 is communicated with the bottom of the box body 126 through the opening, so that the dust can fall into the dust collection box 128.

[0161] 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.

[0162] 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, so that the dust collection box 128 can be arranged at the end of the air conditioner indoor unit, which can save the space occupied in the air conditioner indoor unit, improve the space utilization rate, and further reduce the size of the air conditioner indoor unit in the length direction, making the air conditioner indoor unit smaller and more beautiful.

[0163] 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.

[0164] 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.

[0165] 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 the first driving gear 12002 to rotate synchronously by driving its output shaft.

[0166] In some embodiments, the cleaning module 12 may include a second driving gear 12003, and 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.

[0167] In some embodiments, the cleaning module 12 may include a third driving gear 12004, and the third driving gear 12004 is connected to the axial end of the first driving brush 1207. The third driving gear 12004 is in meshing transmission with the second driving gear 12003. When the second driving gear 12003 rotates, it drives the third driving gear 12004 to rotate, and the third driving gear 12004 drives the first driving brush 1207 to rotate synchronously.

[0168] The first driving motor 12001 drives the output shaft to rotate 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.

[0169] 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.

[0170] 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.

[0171] Define the line connecting the axis O of the first driving brush 1207 and the first end point b as the first connection line, define the line connecting the axis O of the first driving brush 1207 and the second end point c as the second connection line, and define the angle between the first connection line and the second connection line as the first included angle a. The opening of the first included angle a faces the recess 1252, and the first included angle a is greater than or equal to 90° and less than or equal to 180°. When the first included angle a is greater than or equal to 90°, the first included 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 included angle a is less than or equal to 180°, the first included 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.

[0172] 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.

[0173] 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 beneficial to increasing the frictional resistance between the filter screen 121 and the first bristles 12072 and facilitating the first driving brush 1207 to drive the filter screen 121 to rotate, improving the cleaning efficiency and transmission reliability of the filter screen 121.

[0174] 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 on the top of the support frame 125, and the first air inlet grille 12005 is detachably connected to the support frame 125.

[0175] 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.

[0176] The connection mode between the first air inlet grille 12005 and the support frame 125 can be snap connection.

[0177] 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.

[0178] 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.

[0179] The connection mode between the second air inlet grille 12006 and the support frame 125 can be snap connection.

[0180] 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.

[0181] See Figures 21 - 25 , in some embodiments, the filter screen 121 may include a mesh portion 1211. The mesh portion 1211 is provided with mesh holes. Indoor air can flow through the mesh holes and flow out from the heat exchange air outlet. Dust can be isolated on the mesh portion 1211 or adsorbed on the mesh portion 1211 by the filter screen 121.

[0182] 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.

[0183] 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.

[0184] 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.

[0185] 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.

[0186] 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 further improve the cleaning efficiency of the first cleaning brush 127 on the filter screen 121.

[0187] 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.

[0188] 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 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, 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 further improve the cleaning efficiency of the first cleaning brush 127 on the filter screen 121.

[0189] In some embodiments, at least a part of the shape of the splicing seam 1212 is set to be one of a polygonal 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 further improve the cleaning efficiency of the first cleaning brush 127 on the filter screen 121.

[0190] In some embodiments, the extending direction of the splicing seam 1212 is inclined relative to the front - rear direction of the main body.

[0191] 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 thermally - fused mesh part 1211 can be made higher, and the splicing seam 1212 after thermal fusion can be prevented from breaking due to low connection strength.

[0192] 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 guaranteed 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.

[0193] See Figures 26 - 31 , in some embodiments, the support frame 125 can 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 towards the 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 at least part of the support frame 125.

[0194] In some embodiments, the first driving brush 1207 can include a first driving roller 12071, and the first driving roller 12071 can rotate around the rotation axis of the first driving roller 12071.

[0195] In some embodiments, the first driving brush 1207 can 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.

[0196] 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.

[0197] 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.

[0198] In some embodiments, in the projection in the thickness 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 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 for the first driving roller 12071 to drive the first brush to rotate and the first brush to drive the filter screen 121 to rotate.

[0199] In some embodiments, at least part of the raised ribs 1253 are arranged to extend along the length direction of the main body to increase the contact area between the filter screen and the raised ribs, and the filter screen 121 surrounds the support frame 125 along the length direction of the main body.

[0200] In some embodiments, the raised ribs 1253 can be arranged to be at least two, and 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: 50 mm > e > 10 mm.

[0201] 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 > 10 mm to avoid the distance between two adjacent raised ribs 1253 being too short.

[0202] e ≤ 10 mm 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 too large driving torque of the first driving brush 1207 driving the filter screen 121 and reducing the reliability of the first driving brush 1207 driving the filter screen 121.

[0203] 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 < 50 mm to avoid the distance between two adjacent raised ribs 1253 being too long.

[0204] 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 then the contact area between the first driving brush 1207 and the protruding ribs 1253 can be reduced, so that the contact area between the first driving brush 1207 and the filter screen 121 is also reduced, and it is easy to have the problem that the first driving brush 1207 cannot effectively drive the filter screen 121 to rotate and slips.

[0205] 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.

[0206] 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 dust filtration efficiency.

[0207] 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 setting of the main body, and can reduce costs and improve aesthetics.

[0208] 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.

[0209] 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.

[0210] If the number of protruding ribs 1253 is set to be 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, making the rotation torque of the first driving brush 1207 to drive the filter screen 121 increase, which is not conducive to the rotation of the filter screen 121.

[0211] 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.

[0212] In some embodiments, the first preset spacing e and the second preset distance f satisfy: e / f < 0.5, so that fewer protruding ribs 1253 in contact with the filter screen 121 are avoided, and slipping between the first driving brush 1207 and the filter screen 121 is avoided.

[0213] 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, that is, the interference area between the filter screen 121 and the first driving brush 1207 will be small, the frictional force for the first driving brush 1207 to drive the filter screen 121 to rotate will be reduced, so that the first driving brush 1207 cannot effectively drive the filter screen 121 to rotate, and slipping between the first driving brush 1207 and the filter screen 121 will occur.

[0214] 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 or 0.49, etc.

[0215] In some embodiments, in the length direction of the main body, at least two protruding ribs 1253 extend with different lengths.

[0216] 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.

[0217] The protruding ribs 1253 can be set to be 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.

[0218] In some embodiments, in the projection on a plane parallel to the length direction of the main body, the extending direction of the protruding ribs 1253 is inclined with respect 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.
