[0075] The air conditioner indoor unit 100 includes a main body having a bottom and a top, a height direction of the main body from the bottom to the top, and a length direction of the main body from one side to the other side. The main body has a front side and a back side, and the side of the main body facing the user is the front side of the main body.

[0076] The main body can include a cabinet 11 arranged in an indoor space, the cabinet 11 having a front side and a back side, and the side of the cabinet 11 facing the user being the front side of the cabinet 11.

[0077] The main body can include a heat exchange air inlet 111 arranged at the top of the cabinet 11. During cooling or heating, indoor air can enter the interior of the cabinet 11 through the heat exchange air inlet 111.

[0078] The main body can include a first cavity arranged in the interior of the cabinet 11, the first cavity being in communication with the heat exchange air inlet 111, and indoor air entering the first cavity through the heat exchange air inlet 111.

[0079] The main body can include a heat exchange air outlet 112 arranged at the bottom of the cabinet 11, and the first cavity being in communication with the heat exchange air inlet 111 and the heat exchange air outlet 112. During cooling or heating, indoor air flows to the first cavity through the heat exchange air inlet 111 and flows to the indoor space through the heat exchange air outlet 112.

[0080] The main body can include an indoor heat exchanger 1001 arranged in the first cavity, the indoor heat exchanger 1001 being used for heat exchange with indoor air entering the first cavity.

[0081] In some embodiments, the main body can include a heat exchange fan arranged in the first cavity, the fan being used to drive indoor air to enter the first cavity through the heat exchange air inlet 111, then flow through the indoor heat exchanger 1001, and then flow to the indoor space through the heat exchange air outlet 112. It can be provided that the fan is arranged at the leeward side of the indoor heat exchanger 1001 to reduce the resistance of the indoor heat exchanger 1001 to air flow and improve the air intake to the indoor space.

[0082] The fan can include a motor and a fan, and the driving shaft of the motor is connected to the fan. The fan is driven to rotate by the motor to drive the air flow in the first cavity.

[0083] In some embodiments, the air conditioner outdoor unit 200 is arranged in an outdoor space, and the air conditioner outdoor unit 200 includes a housing, a second cavity arranged in the housing, and an outdoor air inlet and an outdoor air outlet arranged on the housing. The outdoor air inlet is in communication with the outdoor space and the second cavity, and the outdoor air outlet is in communication with the outdoor space and the second cavity.

[0084] In some embodiments, the housing is provided with an outdoor heat exchanger 202, and a refrigerant flows through the outdoor heat exchanger 202. The refrigerant in the outdoor heat exchanger 202 can be used to exchange heat with air flowing through the outdoor heat exchanger 202.

[0085] In some embodiments, the housing is provided with a compressor 201, and the compressor 201 is disposed in the second cavity. The compressor 201 is installed at the bottom of the air conditioner outdoor unit 200.

[0086] In some embodiments, the air conditioner outdoor unit 200 can include a throttling device 204 disposed in the second cavity. The throttling device 204 is used to expand the high-temperature and high-pressure liquid-phase refrigerant into low-pressure liquid-phase refrigerant. The throttling device 204 can be disposed at the leeward side of the outdoor heat exchanger 202, which can facilitate connection with the compressor 201.

[0087] The air conditioner 1000 performs a 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 refrigerant to air that has been conditioned and heat-exchanged.

[0088] The compressor 201 compresses low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure refrigerant gas. The discharged refrigerant gas flows into the outdoor heat exchanger 202.

[0089] 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.

[0090] The throttling device 204 expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the outdoor heat exchanger 202 into low-pressure liquid-phase refrigerant.

[0091] The indoor heat exchanger 1001 evaporates the refrigerant expanded in the throttling device 204 and returns the low-temperature and low-pressure refrigerant gas to the compressor 201.

[0092] The indoor heat exchanger 1001 can achieve a refrigeration effect by exchanging heat with a material to be cooled using the latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner 1000 can adjust the temperature of the indoor space.

[0093] In both the indoor heat exchanger 1001 and the outdoor heat exchanger 202, one of which is a condenser and the other of which 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 is used as a heater in a 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 is used as a cooler in a cooling mode.

[0094] Referring to FIGS. 3-10, in some embodiments, the main body can further include a cleaning module 12 corresponding to the heat exchange air inlet 111, the cleaning module 12 being configured to clean dust on a filter screen 121.

[0095] In some embodiments, the cleaning module 12 can include a support frame 125 corresponding to the heat exchange air inlet.

[0096] The portion of the support frame 125 corresponding to the heat exchange air inlet 111 is hollowed out, so that 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.

[0097] In some embodiments, the cleaning module 12 can include a filter screen 121 corresponding to the heat exchange air inlet 111, air being able to flow through the heat exchange air inlet 111, the filter screen 121, and the support frame 125, and out through the heat exchange air outlet 112.

[0098] 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 annular.

[0099] In some embodiments, the cleaning module 12 can include a first driving brush 1207 arranged outside the filter screen 121, the first driving brush 1207 being configured to drive the filter screen 121 to rotate.

[0100] 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 moves around the support frame 125.

[0101] In some embodiments, the cleaning module 12 can include a first cleaning brush 127 arranged outside the filter screen 121, the first cleaning brush 127 being in abutment with the filter screen 121, and the first cleaning brush 127 being configured to brush dust off the filter screen 121.

[0102] When the filter screen 121 is driven to move 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 dust off the filter screen 121, thereby cleaning the filter screen 121.

[0103] In some embodiments, the support frame 125 can include a recessed portion 1252 recessed toward the inside of the support frame 125.

[0104] The recess 1252 is adapted to the first driving brush 1207, at least part of the first driving brush 1207 is arranged in the recess 1252, and at least part of the filter screen 121 is arranged between the recess 1252 and the first driving brush 1207. The filter screen 121 arranged between the recess 1252 and the first driving brush 1207 is arranged around the periphery of the first driving brush 1207, and the first driving brush 1207 abuts against the filter screen 121 to drive the rotation of the filter screen 121.

[0105] At least part of the filter screen 121 is arranged between the recess 1252 and the first driving brush 1207, and 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. This can prevent the first driving brush 1207 from slipping with the filter screen 121 when the first driving brush 1207 rotates, and prevent affecting the transmission and cleaning effect of the filter screen 121.

[0106] In some embodiments, the first driving brush 1207 can include a first driving roller 12071, at least part of the first driving roller 12071 is arranged in the recess 1252, and the first driving roller 12071 is arranged in a substantially cylindrical shape and can rotate about its rotation axis.

[0107] Referring to FIGS. 6-14, in some embodiments, the first driving brush 1207 can include first bristles 12072 arranged on the surface of the first driving roller 12071, and the first bristles 12072 contact and drive the rotation of the filter screen 121.

[0108] In some embodiments, the first driving roller 12071 rotates to drive the rotation of the first bristles 12072, and the first bristles 12072 can drive the rotation of the filter screen 121.

[0109] The first bristles 12072 are uniformly distributed on the surface of the first driving roller 12071, and 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, i.e., to increase the frictional resistance between the first driving brush 1207 and the filter screen 121. This can avoid 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.

[0110] In some embodiments, the cleaning module 12 can include a first steering column 12081 arranged on the inner side of 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.

[0111] The first rotating column 12081 is rotationally connected to the first end of the support frame 125, and the filter screen 121 is arranged around the periphery of the first rotating column 12081.

[0112] In some embodiments, the cleaning module 12 can include a second rotating column 12082 arranged on the inner side of the filter screen 121, the second rotating column 12082 abuts against the filter screen 121, and the second rotating column 12082 is rotatable relative to the filter screen 121.

[0113] The second rotating column 12082 is rotationally connected to the second end of the support frame 125, and the first end and the second end of the support frame 125 are opposite ends of the support frame 125, respectively. The filter screen 121 is arranged around the periphery of the second rotating column 12082.

[0114] The second rotating column 12082 and the first rotating column 12081 are arranged at opposite ends of the support frame 125 to support the filter screen 121. When the first driving brush 1207 drives the filter screen 121 to rotate, the first rotating column 12081 and the second rotating column 12082 rotate relative to the support frame 125 to reduce the frictional resistance between the filter screen 121 and the first rotating column 12081 and the second rotating column 12082, facilitating the rotation of the filter screen 121 and avoiding the filter screen 121 from slipping relative to the first driving brush 1207 due to excessive frictional resistance.

[0115] In some embodiments, the cleaning module 12 can further include a box body 126, the bottom and the side of the box body 126 can be provided with openings, the first driving brush 1207 and the first cleaning brush 127 are arranged in the box body 126, at least part of the filter screen 121 passes through the openings of the side of the box body 126 to be arranged in the box body 126, and the first driving brush 1207 and the first cleaning brush 127 are rotationally connected to the box body 126. The box body 126 supports and connects the first driving brush 1207 and the first cleaning brush 127.

[0116] In some embodiments, the first cleaning brush 127 can include a second driving roller 1273 arranged below the filter screen 121, and the second driving roller 1273 is rotationally connected to the box body 126.

[0117] The second driving roller 1273 is substantially cylindrical, and the two ends of the second driving roller 1273 in the axial direction are rotationally connected to the box body 126, and the second driving roller 1273 is rotatable about its axis.

[0118] In some embodiments, the first cleaning brush 127 can include second bristles 1274 arranged on the surface of the second driving roller 1273, and the second bristles 1274 are in contact with the filter screen 121.

[0119] In some embodiments, the second driving roller 1273 rotates to drive the second bristles 1274 to rotate, and the second bristles 1274 can contact and move relative to the filter screen 121.

[0120] The second bristles 1274 are uniformly distributed on the surface of the second driving roller 1273, and the first cleaning brush 127 can rotate in the opposite direction relative 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.

[0121] Referring to FIG. 15, in some embodiments, the cleaning module 12 can include a second cleaning comb 1209, which is arranged in the box body 126 and fixedly connected with the box body 126.

[0131] 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 falls into the dust collection box 128.

[0132] The dust collection box 128 can be pulled out, which facilitates the user to pull out the dust collection box 128 and clean the dust in the dust collection box 128.

[0133] 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 as to arrange the dust collection box 128 at the end of the air conditioner indoor unit, save the space occupation in the air conditioner indoor unit, improve the space utilization, and then reduce the size of the air conditioner indoor unit in the length direction, so that the air conditioner indoor unit is smaller and more beautiful.

[0134] Referring to FIGS. 6-19, in some embodiments, the cleaning module 12 can include a first driving motor 12001 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 the output shaft to rotate.

[0135] In some embodiments, the cleaning module 12 can include a first driving gear 12002 connected to the output shaft of the first driving motor 12001.

[0136] 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 the output shaft.

[0137] In some embodiments, the cleaning module 12 can include a second driving gear 12003 connected to the axial end of the first cleaning brush 127, and the second driving gear 12003 is in meshing transmission with the first driving gear 12002. When the first driving gear 12002 rotates, the second driving gear 12003 rotates, and the second driving gear 12003 drives the first cleaning brush 127 to rotate synchronously.

[0138] In some embodiments, the cleaning module 12 can include a third drive gear 12004 connected to the end of the first drive brush 1207 axially, the third drive gear 12004 is in mesh transmission with the second drive gear 12003, the second drive gear 12003 drives the third drive gear 12004 to rotate when rotating, and the third drive gear 12004 drives the first drive brush 1207 to rotate synchronously.

[0139] The first drive motor 12001 drives the first drive gear 12002 to rotate through the drive output shaft, the first drive gear 12002 drives the second drive gear 12003 and the first cleaning brush 127 to rotate, the second drive gear 12003 drives the third drive gear 12004 and the first drive brush 1207 to rotate, and the first drive brush 1207 drives the filter screen 121 to move through frictional resistance.

[0140] The first drive brush 1207 rotates clockwise, and the frictional resistance makes the first drive brush 1207 drive the filter screen 121 to rotate counterclockwise around the support frame 125, so as to rotate the filter screen 121 to contact the first cleaning brush 127 to clean the filter screen 121. The first cleaning brush 127 rotates counterclockwise, and the rotating direction of the first cleaning brush 127 is opposite to that of the filter screen 121, which can increase the frictional resistance between the first cleaning brush 127 and the filter screen 121, and further improve the cleaning effect of the first cleaning brush on the filter screen 121.

[0141] Referring to FIG. 20, in some embodiments, the recess 1252 is located on one side of the length direction of the heat exchange air inlet, and in the length direction of the heat exchange air inlet, the closest point of the recess to the heat exchange air inlet is defined as the first end point b, and the farthest point of the recess 1252 to the heat exchange air inlet is defined as the second end point c.

[0142] A first line is defined as a line between the axis O of the first driving brush 1207 and the first end point b, a second line is defined as a line between the axis O of the first driving brush 1207 and the second end point c, a first included angle a is defined as an included angle between the first line and the second line, the first included angle a is opened towards the recess 1252, 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 is not too small, 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 increase the frictional resistance between the first driving brush 1207 and the filter screen 121, and prevent 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 is not too large, the contact area between the filter screen 121 and the first driving brush 1207 in the recess is not too large, and the frictional resistance between the filter screen 121 and the first driving brush 1207 in the recess is not too large, which can avoid the problem that the first driving brush 1207 cannot rotate due to the too large frictional resistance.

[0143] Referring to FIGS. 6-19, in some embodiments, the support frame 125 can include a raised rib 1253, the raised rib 1253 is arranged in the recess 1252, the raised rib 1253 is connected with the recess 1252, and the raised rib 1253 can be integrally formed with the support frame 125.

[0144] The raised rib 1253 protrudes and extends towards the first driving brush 1207, and the raised rib 1253 is in contact with the filter screen 121 to have a gap between the filter screen 121 and the recess 1252. The gap between the filter screen 121 and the recess 1252 allows the first bristles 12072 on the first driving brush 1207 to penetrate the filter screen 121, at least part of the first bristles 12072 can penetrate into the gap between the filter screen 121 and the recess 1252, which can increase the frictional resistance between the filter screen 121 and the first bristles 12072, and is beneficial to the rotation of the first driving brush 1207 driving the filter screen 121, and improves the cleaning efficiency and transmission reliability of the filter screen 121.

[0145] In some embodiments, the cleaning module 12 can include a first air inlet grille 12005, and the first air inlet grille 12005 is connected with the support frame 125. The first air inlet grille 12005 is arranged at the top of the support frame 125, and the first air inlet grille 12005 is detachably connected with the support frame 125.

[0146] The first air inlet grille 12005 is located at the top of the filter screen 121, and the first air inlet grille 12005 can limit the filter screen 121 to prevent the filter screen 121 from being separated from the support frame 125.

[0147] The connection mode between the first air inlet grille 12005 and the support frame 125 can be clamping connection.

[0148] The cleaning module 12 can include a second air inlet grille 12006, which is arranged at the bottom of the support frame 125 and is detachably connected with the support frame 125.

[0149] The second air inlet grille 12006 is located at the bottom of the filter screen 121 and can limit the filter screen 121 to prevent the filter screen 121 from being separated from the support frame 125.

[0150] The connection mode between the second air inlet grille 12006 and the support frame 125 can be clamping connection.

[0151] The filter screen 121 is limited between the first air inlet grille 12005 and the second air inlet grille 12006, which can prevent the filter screen 121 from falling off.

[0152] Referring to FIGS. 21-25, in some embodiments, the filter screen 121 can include a mesh portion 1211, which is provided with mesh holes through which indoor air can flow out of the heat exchange air outlet, and dust can be isolated on or adsorbed on the mesh portion 1211.

[0153] In some embodiments, the filter screen 121 can include a spliced seam 1212 connected with the mesh portion 1211, and the mesh portion 1211 is integrally heat-fused at the spliced seam 1212.

[0154] The mesh portion 1211 is integrally heat-fused at the spliced seam 1212, that is, the filter screen 121 at the spliced seam 1212 is integrally heat-fused, and the mesh holes at the spliced seam 1212 are heat-fused and eliminated. When the spliced seam 1212 is rotated to contact the first driving brush 1207, the first bristles 12072 cannot pass through the spliced seam 1212, so that the frictional resistance between the spliced 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.

[0155] In some embodiments, the first driving brush 1207 can include a first driving roller shaft 12071, which can rotate about a rotation axis of the first driving roller shaft 12071.

[0156] In some embodiments, the first driving brush 1207 can include first bristles 12072 arranged on the surface of the first driving roller shaft 12071, and the first bristles 12072 can penetrate the mesh holes.

[0157] When at least part of the joint 1212 is in contact with the first driving brush 1207, at least part of the mesh portion 1211 is in contact with the first driving brush 1207, i.e. when the joint 1212 rotates to be in contact with the first driving brush 1207, at this time, part of the mesh portion 1211 is also in contact with the first driving brush 1207, and part of the first bristles 12072 of the first driving brush 1207 can pass through the mesh holes of the mesh portion 1211. The first driving roller 12071 rotates to drive the first bristles 12072 to rotate, and the first bristles 12072 drive the filter screen 121 to rotate. When the first driving brush 1207 is in contact with the filter screen 121 and drives the filter screen 121 to rotate by 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.

[0158] In some embodiments, the first driving brush 1207 rotates around its rotation axis, and in the direction of the rotation axis of the first driving brush 1207, the contact position of the first driving brush 1207 with the filter screen 121 is linear.

[0159] The extension direction of the joint 1212 is not parallel to the rotation axis of the first driving brush 1207, which can make the contact surface of the first driving brush 1207 with the filter screen 121 staggered with the joint 1212 when the first driving brush 1207 is in contact with the joint 1212. When the joint 1212 rotates to be in contact with the first driving brush 1207, part of the mesh portion 1211 is also in contact with the first driving brush 1207, so that part of the first bristles 12072 of the first driving brush 1207 can pass through the mesh holes of the mesh portion 1211. When the first driving brush 1207 is in contact with the filter screen 121 and drives the filter screen 121 to rotate by 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.

[0160] In some embodiments, at least part of the joint 1212 is shaped as one of a broken line, an arc, and a sine wave, i.e. the joint 1212 can be shaped as a non-straight line, which can make the first driving brush 1207 in contact with at least part of the mesh portion 1211 when the joint 1212 is in contact with the first driving brush 1207, so that part of the first bristles 12072 of the first driving brush 1207 can pass through the mesh holes of the mesh portion 1211. When the first driving brush 1207 is in contact with the filter screen 121 and drives the filter screen 121 to rotate by 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.

[0161] In some embodiments, the extension direction of the splicing joint 1212 is inclined relative to the front-rear direction of the main body.

[0162] In some embodiments, the width direction of the splicing joint 1212 is arranged in the same direction as the length direction of the main body, and the width d of the splicing joint 1212 can be any value within the range of 3 mm to 6 mm. The width d of the splicing joint 1212 can be 3 mm. When the width d of the splicing joint 1212 is greater than or equal to 3 mm, the width of the splicing joint 1212 is not too small, the connection strength of the mesh part 1211 of the hot melt connection is higher, and the splicing joint 1212 after hot melting is prevented from being broken due to low connection strength.

[0163] The width d of the splicing joint 1212 can be 6 mm. When the width d of the splicing joint 1212 is less than or equal to 6 mm, the width d of the splicing joint 1212 is not too large. When the first driving brush 1207 contacts the splicing joint 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 hole, thereby increasing the frictional resistance, which is beneficial to the transmission efficiency of the filter screen 121 and prevents slipping. When the width of the splicing joint 1212 is greater than 6 mm, it cannot be ensured that when the first driving brush 1207 contacts the splicing joint 1212, the first driving brush 1207 also contacts the mesh part 1211, thereby causing the problem of slipping when the first driving brush 1207 drives the filter screen 121 to move.

[0164] Referring to FIGS. 26-31, in some embodiments, the support frame 125 can include a raised rib 1253 corresponding to the first driving brush 1207. The raised rib 1253 extends outwardly toward the first driving brush 1207. The raised rib 1253 contacts the filter screen 121 to form a first gap between the filter screen 121 and the support frame 125.

[0165] In some embodiments, the first driving brush 1207 can include a first driving roller shaft 12071, which can rotate about a rotation axis of the first driving roller shaft 12071.

[0166] In some embodiments, the first driving brush 1207 can include first bristles 12072 arranged on the surface of the first driving roller shaft 12071. The first bristles 12072 can penetrate the mesh hole.

[0167] 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 to form a first gap 1254 between the filter screen 121 and the support frame 125.

[0168] The first driving roller 12071 rotates to drive the first bristles 12072 to rotate, and the rotation of the first bristles 12072 drives the filter screen 121 to rotate. When the filter screen 121 is in contact with the first driving brush 1207, at least part of the first bristles 12072 passes through the mesh holes into the first gap 1254, which can increase the friction between the first bristles 12072 and the filter screen 121, and improve the reliability of the filter screen 121 driven to rotate by the first bristles.

[0169] In some embodiments, at least part of the first bristles 12072 overlaps the raised ribs 1253 in the height direction of the main body, that is, part of the first bristles 12072 passes through the filter screen 121 and overlaps the raised ribs 1253 in the height direction of the main body. Part of the first bristles 12072 passes through the filter screen 121 and is located in the first gap 1254, which can increase the friction between the first bristles 12072 and the filter screen 121, and facilitate the rotation of the filter screen 121 driven by the first bristles when the first driving roller 12071 drives the first brush to rotate.

[0170] 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 is arranged around the support frame 125 along the length direction of the main body.

[0171] In some embodiments, the raised ribs 1253 can be provided as at least two, and the at least two raised ribs 1253 are arranged at intervals. In the direction in which the raised ribs 1253 are arranged at intervals, the first preset interval e between adjacent two raised ribs 1253 satisfies: 50mm>e>10mm.

[0172] In some embodiments, the direction in which the raised ribs 1253 are arranged at intervals 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 the arrangement direction, the first preset interval e satisfies e>10mm, so as to avoid that the interval between adjacent two raised ribs 1253 is too short.

[0173] e≤10mm, which can make the interval between adjacent two raised ribs 1253 too short, so that the number of the raised ribs 1253 is relatively large, and then the contact area between the filter screen 121 and the raised ribs 1253 is too large, and the friction between the filter screen 121 and the raised ribs 1253 is relatively large, which can cause the driving torque of the first driving brush 1207 to drive the filter screen 121 to be too large, and the reliability of the first driving brush 1207 to drive the filter screen 121 to be reduced.

[0174] 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 the arrangement direction, the first preset interval e satisfies e<50mm, so as to avoid that the interval between adjacent two raised ribs 1253 is too long.

[0175] If the distance between two adjacent protruding ribs 1253 is too long, that is, e≥50 mm, the number of protruding ribs 1253 is small, and the contact area between the first driving brush 1207 and the protruding ribs 1253 is small, so that the contact area between the first driving brush 1207 and the filter screen 121 is small, and the problem that the first driving brush 1207 cannot effectively drive the filter screen 121 to rotate and slip easily occurs.

[0176] In some embodiments, the width of the filter screen 121 is a second preset distance f, and the width direction of the filter screen 121 is arranged in the same direction as the length direction of the rotation axis of the first driving roller 12071, and f>150 mm is satisfied. The width of the filter screen 121 can be avoided to be small, and the air flowing into the heat exchange air inlet can be effectively filtered by the filter screen 121, and the air inlet amount and dust filtering efficiency of the heat exchange air inlet can be ensured.

[0177] If the width of the filter screen 121 is set too small, for example, f≤150 mm, the width of the filter screen 121 is small, and the air flowing into the heat exchange air inlet cannot be effectively filtered by the filter screen 121, and the dust filtering efficiency is reduced.

[0178] In some embodiments, the width of the filter screen 121 is a second preset distance f, and the width direction of the filter screen 121 is arranged in the same direction as the length direction of the rotation axis of the first driving roller 12071, and f<200 mm is satisfied. The width of the filter screen 121 can be avoided to be large, and the filter screen 121 can avoid occupying a large space, and the size of the main body can be avoided to be large, and the cost can be reduced and the aesthetic appearance can be improved.

[0179] If the width of the filter screen 121 is large, that is, f≥200 mm, the filter screen 121 occupies a large space, and the size of the main body is large, which increases the cost and affects the aesthetic appearance.

[0180] In some embodiments, the first preset distance e and the second preset distance f satisfy e / f>0.1, so as to avoid that the number of protruding ribs 1253 in contact with the filter screen 121 is large, and the first driving brush 1207 cannot effectively drive the filter screen 121 to rotate.

[0181] If the number of protruding ribs 1253 is set to be large, that is, e / f<0.1, the contact area between the filter screen 121 and the protruding ribs 1253 is large, that is, the interference area between the protruding ribs 1253 and the first driving brush 1207 is large, which increases the friction force of the first driving brush 1207 driving the filter screen 121 to rotate, and the torque of the first driving brush 1207 driving the filter screen 121 to rotate is increased, which is not conducive to the rotation of the filter screen 121.

[0182] Specifically, the ratio of the first preset distance e and the second preset distance f can be 0.11, 0.15, 0.2 or 0.25, etc.

[0183] In some embodiments, the first preset distance e and the second preset distance f satisfy: e / f < 0.5, so as to avoid less convex ribs 1253 in contact with the filter screen 121, and avoid the first driving brush 1207 from slipping with the filter screen 121.

[0184] If the number of convex ribs 1253 is set to be less, i.e., e / f ≥ 0.5, the contact area between the filter screen 121 and the convex ribs 1253 is small, i.e., the interference area between the filter screen 121 and the first driving brush 1207 is small, which reduces the friction force of the first driving brush 1207 driving the filter screen 121 to rotate, so that the first driving brush 1207 cannot effectively drive the filter screen 121 to rotate, and the first driving brush 1207 slips with the filter screen 121.

[0185] Specifically, the ratio of the first preset distance e and the second preset distance f can be 0.3, 0.33, 0.4, 0.45, or 0.49, etc.

[0186] In some embodiments, the lengths of the at least two convex ribs 1253 extending in the length direction of the main body are different.

[0187] In some embodiments, at least part of the convex ribs 1253 are arranged to extend along the length direction of the rotation axis of the first driving roller 12071.

[0188] The convex ribs 1253 can be arranged in at least two, and the at least two convex ribs 1253 are arranged at intervals. The direction in which the convex ribs 1253 are arranged at intervals can be the length direction of the main body. This can increase the interference area between the convex ribs 1253 and the first driving brush 1207, which is conducive to the first driving brush 1207 driving the filter screen 121.

[0189] In some embodiments, in the projection of the main body in the height direction, the extension direction of the convex ribs 1253 is inclined relative to the length direction of the main body, which can cause the convex ribs 1253 to interfere with the first driving brush 1207, and is conducive to the first driving brush 1207 driving the filter screen 121 to rotate.

[0190] Referring to FIGS. 32-40, in some embodiments, the cleaning module can include a first deflection roller 12007, which is arranged on the inner side of the filter screen 121, and the first deflection roller 12007 is rotationally connected to the support frame.

[0191] In some embodiments, the first deflection roller 12007 can be arranged as a cylindrical roller to reduce the friction force between the first deflection roller 12007 and the filter screen 121.

[0192] In some embodiments, the first deflection roller 12007 is located on the same side of the support frame as the first cleaning brush, and the filter screen 121 extends around the bottom of the first deflection roller 12007 between the first driving brush 1207 and the support frame.

[0193] In some embodiments, the first deflection roller 12007 is located on the same side of the support frame as the first cleaning brush, and the filter screen 121 extends around the bottom of the first deflection roller 12007 between the first driving brush 1207 and the support frame.

[0194] In some embodiments, the first deflection roller 12007 is located on the same side of the support frame as the first cleaning brush, and the filter screen 121 extends around the bottom of the first deflection roller 12007 between the first driving brush 1207 and the support frame.

[0195] In some embodiments, the first deflection roller 12007 is located on the same side of the support frame as the first cleaning brush, and the filter screen 121 extends around the bottom of the first deflection roller 12007 between the first driving brush 1207 and the support frame.

[0196] In some embodiments, the first deflection roller 12007 is located on the same side of the support frame as the first cleaning brush, and the filter screen 121 extends around the bottom of the first deflection roller 12007 between the first driving brush 1207 and the support frame.

[0197] If the ratio of the third preset distance g and the fourth preset distance h is too large, for example, g / h≥0.6, that is, if the distance between the bottom of the first deflection 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 between the filter screen 121 and the first driving brush 1207, and in turn excessively increase the rotation torque of the first driving brush 1207, which is not conducive to the rotation of the filter screen 121 driven by the first driving brush 1207.

[0198] Specifically, the ratio between the third preset distance g and the fourth preset distance h can be 0.55, 0.5, 0.44, or 0.41.

[0199] In some embodiments, in the height direction of the main body, the distance between the bottom of the first deflection 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 of the first driving brush 1207 and the bottom of the first driving brush 1207 is set as the fourth preset distance h, and g / h>0.1.

[0200] The top of the first driving brush 1207 is defined as the topmost part of the first bristles 12072 arranged 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 arranged 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>0.1, which can increase the contact area between the filter screen 121 and the first driving brush 1207, increase the curvature of the contact area between the filter screen 121 and the first driving brush 1207, and is conducive to improving the driving efficiency of the first driving brush 1207 on the filter screen 121.

[0201] If the ratio of the third preset distance g and the fourth preset distance h is too small, for example, g / h≤0.1, that is, if the distance between the bottom of the first deflection 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 between the filter screen 121 and the first driving brush 1207, and in turn cause the first driving brush 1207 to slip when driving the filter screen 121, which is not conducive to the rotation of the filter screen 121 driven by the first driving brush 1207.

[0202] Specifically, the ratio between the third preset distance g and the fourth preset distance h can be 0.11, 0.16, 0.22, 0.3, or 0.4.

[0204] In some embodiments, the second deflection roller 12008 is rotationally connected to the support frame.

[0205] In some embodiments, the second deflection roller 12008 can be provided as a cylindrical roller to reduce the friction between the second deflection roller 12008 and the filter screen 121.

[0206] In some embodiments, in the height direction of the main body, the distance between the bottom of the second deflection roller 12008 and the top of the first driving brush 1207 is set as a fifth preset interval i, and the distance between the top of the first driving brush 1207 and the bottom of the first driving brush 1207 is set as a fourth preset interval h, and i / h>0.1 is satisfied.

[0208] If the proportional relationship between the fifth preset interval i and the fourth preset interval h is too small, for example, i / h≤0.1, that is, if the distance between the bottom of the second deflection 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 friction 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 rotation of the first driving brush 1207 on the filter screen 121.

[0209] Specifically, the ratio between the fifth preset interval i and the fourth preset interval h can be 0.11, 0.16, 0.22, 0.3, or 0.4.

[0210] In some embodiments, the distance between the bottom of the second deflection roller 12008 and the top of the first driving brush 1207 is set as a fifth preset interval i, and the distance between the top of the first driving brush 1207 and the bottom of the first driving brush 1207 is set as a fourth preset interval h, and i / h < 0.6 is satisfied.

In the height direction of the main body, the fifth preset interval i and the fourth preset interval h satisfy a proportional relationship, such as i / h < 0.6, which can appropriately reduce the contact area of the filter screen 121 with the first driving brush 1207, reduce the curvature of the contact area of the filter screen 121 with the first driving brush 1207, and be beneficial to reducing the driving resistance between the first driving brush 1207 and the filter screen 121.

[0212] If the proportional relationship between the fifth preset interval i and the fourth preset interval h is too large, for example, i / h ≥ 0.6, that is, if the distance between the bottom of the second deflection roller 12008 and the top of the first driving brush 1207 is too large, it will make the contact area between the filter screen 121 and the first driving brush 1207 too large, which will excessively increase the friction between the filter screen 121 and the first driving brush 1207, and further excessively increase the rotation torque of the first driving brush 1207, which is not conducive to the driving of the first driving brush 1207 to rotate the filter screen 121.

[0213] Specifically, the ratio between the fifth preset interval i and the fourth preset interval h can be 0.55, 0.5, 0.44, or 0.41.

[0214] Referring to FIGS. 38-40, in some embodiments, the cleaning module can include a third deflection roller 12009 arranged outside the filter screen 121, the third deflection roller 12009 and the second deflection roller 12008 are arranged on the same side of the first driving brush 1207, the filter screen 121 is inclined upward from the periphery of the bottom of the second deflection roller 12008 to the top of the third deflection roller 12009, the top of the third deflection roller 12009 is in contact with the filter screen 121, and the third deflection roller 12009 is rotatable to reduce the friction between the filter screen 121 and the third deflection roller 12009 and reduce the transmission resistance of the filter screen 121.

[0215] In some embodiments, the third deflection roller 12009 is rotatably connected to the support frame.

[0220] Specifically, the second included angle j can be 5°, 14°, 22°, or 25°.

The second included angle j less than 45° can cause the tangent line when the filter screen 121 contacts the third driving roller to be not too steep, appropriately reduce the force of the filter screen 121 on the third driving roller, and further reduce the friction between the filter screen 121 and the third driving roller, thereby improving the rotation efficiency of the filter screen 121.

[0223] If the second included angle is too large, i.e., the second included angle j is greater than or equal to 45°, the tangent line when the filter screen 121 contacts the third driving roller will be too steep, the force of the filter screen 121 on the third driving roller will be increased, and the friction between the filter screen 121 and the third driving roller will be increased, which will increase the resistance of the filter screen 121 to rotate and affect the rotation efficiency of the filter screen 121.

[0224] In some embodiments, the contact surface between the filter screen 121 and the first driving brush 1207 is an arc surface, and the curvature of the contact surface satisfies: θ < 200°. When θ < 200°, the contact surface between the filter screen 121 and the first driving brush 1207 can be ensured not to be too large, the friction between the first driving brush 1207 and the filter screen 121 can be moderate, the rotation 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 the cleaning efficiency of the first cleaning brush on the filter screen 121 can be improved.

[0225] If θ is too large, i.e., θ > 200°, the area of the contact surface between the filter screen 121 and the first driving brush 1207 can be too large, the friction between the filter screen 121 and the first driving brush 1207 can be large, the rotation torque of the first driving brush 1207 can be increased, the first driving brush 1207 can be not conducive to driving the filter screen 121 to rotate, and the cleaning efficiency of the filter screen 121 can be affected.

[0226] Specifically, θ can be 199°, 186°, 167°, 150°, or 143°.

[0227] In some embodiments, the contact surface between the filter screen 121 and the first driving brush 1207 is an arc surface, and the curvature of the contact surface satisfies: θ > 90°. When θ > 90°, the contact surface between the filter screen 121 and the first driving brush 1207 can be ensured not to be too small, the friction between the first driving brush 1207 and the filter screen 121 can be moderate, the first driving brush 1207 can be prevented 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 the cleaning efficiency of the first cleaning brush on the filter screen 121 can be improved.

[0228] If θ is too small, i.e., θ < 90°, the area of the contact surface between the filter screen 121 and the first driving brush 1207 can be too small, the friction between the filter screen 121 and the first driving brush 1207 can be small, the first driving brush 1207 can slip when driving the filter screen 121 to move, the first driving brush 1207 can be not conducive to driving the filter screen 121 to rotate, and the cleaning efficiency of the filter screen 121 can be affected.
