Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning indoor unit. Background Art

[0002] Currently, the air inlet of the indoor unit of a wall-mounted air conditioner is equipped with a filter. This filter is used to filter the air drawn into the indoor unit, improving indoor air quality and ensuring normal operation of the indoor unit. To prevent dust on the filter from causing secondary pollution to the indoor air, users need to clean the dust on the filter regularly. However, the filter must be manually removed before cleaning, which is a cumbersome process.

[0003] To this end, some existing indoor units are equipped with a rotatable roller brush inside. By driving the filter to reciprocate along a preset trajectory so that the roller brush contacts the filter, the roller brush automatically cleans the dust on the surface of the filter and collects it uniformly, realizing automatic cleaning of the dust on the surface of the filter, which is intelligent and convenient to operate. Among them, a detachable dust box is installed on the front side of the indoor unit. The dust box is used to collect the dust brushed by the roller brush, and then the roller brush and the dust box are placed outdoors together for dust removal. However, the disassembly and assembly methods of the roller brush and the dust box in the existing technology are relatively independent and cumbersome, resulting in the roller brush easily shedding dust during the disassembly process, causing secondary pollution to the indoor environment and reducing the user experience. Summary of the Invention

[0004] The purpose of the present invention is to provide an air-conditioning indoor unit, whose roller brush and dust box can be removed at the same time, and the disassembly and assembly structure is simple and convenient, avoiding dust falling during the disassembly process and ensuring the cleanliness of the indoor air.

[0014] A motor, wherein a driving gear is provided on a power output end of the motor;

[0015] A first driven gear is engaged with the driving gear, and the socket is provided on the first driven gear.

[0016] In some embodiments, the roller brush comprises:

[0017] a first rotating shaft, wherein both ends of the first rotating shaft are respectively rotatably provided on the left and right sides of the dust collection box, one end of the first rotating shaft has an inserting portion, a plurality of limiting protrusions are spaced apart on the outer periphery of the inserting portion, and a cross-sectional shape of the socket is adapted to a cross-sectional shape of the first rotating shaft;

[0018] A roller brush is sleeved on the first rotating shaft and is in rolling contact with the filter to clean the filter.

[0019] In some embodiments, the filter device further includes a roller disposed in the bracket, with two ends of the roller rotatably passing through opposite sides of the bracket, and the roller is located above the dust box;

[0020] The driving device further comprises:

[0021] The second driven gear and the second transmission gear are engaged with the driving gear, one end of the roller is passed through the second driven gear, and the roller can rotate to drive the filter to reciprocate along a preset path.

[0022] In some embodiments, slides are respectively provided on the left and right sides of the bracket, and the two slides are arranged opposite to each other. The left and right sides of the filter are arranged in each slide in a one-to-one correspondence, and the roller drives the filter to reciprocate along the slide.

[0023] In some embodiments, the roller comprises:

[0024] a second rotating shaft, wherein both ends of the second rotating shaft are rotatably provided on the left and right sides of the bracket, and one end of the second rotating shaft is provided on the second driven gear;

[0025] a cylinder, wherein the cylinder is sleeved on the second rotating shaft;

[0026] Two gears are respectively located at the two ends of the cylinder and sleeved on the second rotating shaft. The left and right sides of the filter screen are respectively provided with rack parts that mesh with the gears.

[0027] In some embodiments, the slideway includes a first slide groove and a second slide groove sequentially arranged in the up-down direction, and the first slide groove and the second slide groove extend in the front-back direction respectively;

[0028] The front end of the first chute is smoothly connected to the front end of the second chute, and the rear end of the first chute and the rear end of the second chute are respectively close to the rear side of the shell and are spaced apart in the up and down direction.

[0029] In some embodiments, a bolt groove is provided on a side of the housing facing away from the assembly and disassembly gap, the bolt is slidably disposed in the bolt groove, and the bolt can slide between a first position and a second position;

[0030] When the bolt is located at the first position, a portion of the bolt abuts against the front side of the dust box to limit the separation of the dust box and the bracket; when the bolt is located at the second position, the bolt and the dust box are separated from each other to release the connection between the dust box and the bracket.

[0031] In some embodiments, a handle protrusion is provided at one end of the dust collecting box close to the assembly and disassembly gap, and a first handle groove is provided on a side of the handle protrusion facing away from the driving device.

[0032] Compared with the prior art, the air conditioner indoor unit of the present invention has the following advantages:

[0033] Since the drive device is located outside the bracket, one end of the roller brush passes through the bracket and can be slidably inserted into the socket of the drive device. When the dust box and roller brush need to be removed from the bracket, the connection between the dust box and the bracket is released by the bolt, so that the dust box can slide left and right in the installation slot. By driving the dust box and roller brush to slide toward the end close to the disassembly gap, the end of the roller brush slides out of the socket, so that the roller brush and the dust box can be removed at the same time, avoiding the phenomenon of dust falling when the roller brush is removed alone, thereby ensuring the cleanliness of the indoor environment. When the dust box and roller brush need to be fixed to the bracket, the dust box and roller brush are driven to slide toward the end away from the disassembly gap, so that the end of the dust box is inserted into the socket of the drive device, so that the roller brush rotates with the power output shaft of the drive device, driving the roller brush to clean the filter. The dust removal device of the present invention is highly detachable from the drive device, effectively avoiding the phenomenon of dust falling from the roller brush or dust box during the disassembly process, which is conducive to improving the user experience.

[0074] Please refer to Figure 1-Figure 26 The air conditioner indoor unit of the embodiment of the present invention includes a housing 1, a filter device 2, a dust removal device 3, a drive device 4, and a bolt 5. The air conditioner indoor unit of the embodiment of the present invention is a wall-mounted air conditioner indoor unit, and the housing 1 is generally elongated and three-dimensional, that is, the length of the housing 1 is greater than its height or width.

[0075] Please refer to Figure 1-Figure 5The housing 1 forms a chamber for accommodating the crossflow fan 6 and heat exchanger 7 of the air conditioner indoor unit. The housing 1 is provided with an air inlet 11 at the top and an air outlet (not shown) at the front bottom. When the crossflow fan 6 is in operation, indoor air is drawn into the chamber through the air inlet 11 at the top of the housing 1. After undergoing heat exchange in the heat exchanger 7 to form cool or hot air, it returns to the room through the air outlet. Specifically, the housing 1 includes a front panel 12, a top panel 13, a back panel (not shown), a bottom panel (not shown), and two end panels 14 located on either side of the front panel 12. Together, the front panel 12, top panel 13, back panel, bottom panel, and the two end panels 14 enclose a chamber. The air inlet 11 is located on the top panel 13. The air inlets 11 are generally square and are spaced apart in the left-right direction. Each air inlet 11 is provided with an air inlet grille to prevent large objects from entering the housing 1 through the air inlet 11. The air outlet is located on the bottom plate, and a rotatable air deflector (not shown) is provided at the outlet to adjust the airflow direction to meet user needs. The front panel 12 has two mounting ports connected to the chamber, and the positions of the mounting ports correspond to the positions of the air inlets 11.

[0076] The filter device 2 is disposed in the chamber of the housing 1 and covers the air inlet 11. Figure 6-Figure 13 、 Figure 15-18 The filter device 2 includes a bracket 21, a filter screen 22 and a roller 23.

[0077] Please refer to Figure 4-Figure 8 、 Figure 15-17 The rear side of the bracket 21 is arc-shaped and concave, and the cross-flow fan 6 and heat exchanger 7 of the air conditioner indoor unit are both arranged on the rear side of the bracket 21. A receiving groove 211 is provided on the rear side of the bracket 21, and a vent 212 corresponding to the position of the air inlet 11 is provided on the top of the bracket 21. The vent 212 is connected to the receiving groove 211, and the air sucked in from the air inlet 11 passes through the vent 212 and the receiving groove 211 in turn and is then sent out from the air outlet. Slides 213 are respectively provided on the left and right inner walls of the receiving groove 211, and the two slides 213 are arranged opposite to each other. The left and right sides of the filter 22 are arranged in each slide 213 in a one-to-one correspondence, and the roller 23 is arranged in the receiving groove 211 to drive the filter 22 to reciprocate along the slide 213.

[0078] It should be noted that in the embodiments of the present invention, the front side refers to the side of the air conditioner indoor unit closest to the user, and the rear side refers to the side of the air conditioner indoor unit facing away from the user. Therefore, the front-to-back direction is the direction from the side closest to the user to the side facing away from the user. The top side is the position of the air conditioner indoor unit facing away from the ground, and the bottom side is the position of the air conditioner indoor unit facing the ground. Therefore, the top-to-bottom direction is the direction from the side facing away from the ground to the side facing the ground.

[0079] Specifically, please refer to Figure 4 、 Figure 17 The slideway 213 includes a first slideway 2131 and a second slideway 2132, arranged in sequence along the vertical direction. The front end of the first slideway 2131 includes an upwardly curved first arc segment 2131a. The front end of the second slideway 2132 includes a second arc segment 2132a and a third arc segment 2132b, arranged along the front-to-back direction. The second arc segment 2132a curves downward, while the third arc segment 2132b curves upward. The first arc segment 2131a, the second arc segment 2132a, and the third arc segment 2132b are sequentially connected. By optimizing the movement trajectory of the slideway 213, the movement space of the filter screen 22 within the accommodating tank 211 is reduced, thereby enabling the installation of a larger heat exchanger 7, effectively increasing the volume of the heat exchanger 7 and the heat exchange area, thereby improving the heat exchange effect. A mounting slot 214 is provided on the front side of the bracket 21, and the rear side of the mounting slot 214 is connected to the accommodating tank 211.

[0080] The first chute 2131 also includes a first horizontal section 2131b located at the rear end of the first curved section 2131a. The second chute 2132 also includes a second horizontal section 2132c located at the rear end of the third curved section 2132b. The first and second horizontal sections 2131b, 2132c, respectively extend to the rear wall of the housing 1 and are spaced apart vertically. When the air conditioner indoor unit is in cooling or heating mode, the filter 22 is located within the first chute 2131. The distance between the filter 22 and the heat exchanger 7 is greater, increasing the heat exchange space and improving the heat exchange efficiency. When the air conditioner indoor unit is in dust removal mode, the filter 22 slides from the first chute 2131 to the second chute 2132, or from the second chute 2132 to the first chute 2131, and the dust removal device 3 cleans dust from the surface of the filter 22.

[0081] Furthermore, the heat exchanger 7 is located behind the notch of the accommodating groove 211. The outer side of the heat exchanger 7 is curved upward, and the top of the heat exchanger 7 is located near the third arcuate segment 2132b and the second horizontal segment 2132c. This fully utilizes the installation space within the housing 1 and increases the heat exchange area of ​​the heat exchanger 7. The heat exchanger 7 of the present invention has the same structure as the heat exchanger of the air conditioner indoor unit in the prior art, and a detailed description thereof is omitted here.

[0082] The first slide groove 2131 is arranged near the ventilation port 212, and the upper side wall of the first horizontal section 2131b and the upper side wall of the rear end of the first arc section 2131a respectively pass through the top of the bracket 21, so that the filter 22 can be inserted into the first slide groove 2131 from the rear end of the air inlet 11 and the rear end of the ventilation port 212 in turn, so that the filter 22 can be detachably assembled into the slide groove 213.

[0083] The bracket 21 is provided with multiple first support rods 215 and multiple second support rods 216. The two ends of each first support rod 215 are respectively connected to the left and right inner walls of the accommodating groove 211, and the multiple first support rods 215 are arranged in sequence along the lower side edge of the first sliding groove 2131; the two ends of each second support rod 216 are respectively connected to the left and right inner walls of the accommodating groove 211, and the multiple second support rods 216 are arranged in sequence along the lower side edge of the second sliding groove 2132. When the filter 22 slides in the first slide groove 2131, the first support rod 215 supports the bottom of the filter 22, preventing the middle part of the filter 22 from being deformed due to gravity, thereby improving the sliding smoothness of the filter 22 in the first slide groove 2131; based on the same principle, when the filter 22 slides in the second slide groove 2132, the second support rod 216 supports the bottom of the filter 22, preventing the middle part of the filter 22 from being deformed due to gravity, thereby improving the sliding smoothness of the filter 22 in the second slide groove 2132.

[0084] The bracket 21 can be a plastic integral part prepared by an injection molding process, which is simple, convenient and efficient.

[0085] Please refer to Figures 18-20 The filter screen 22 includes a grid 221 and a filter screen 222. A hollow portion 2211 is provided in the central area of ​​the grid 221. Rack portions 2212 are provided on the left and right edges of the hollow portion 2211 on the grid 221. The left and right edges of the grid 221 extend outward to form flanges 2213. Each flange 2213 is provided with a plurality of notches 2214 arranged in sequence along the up and down directions, and the positions of the notches 2214 on the flanges 2213 on the left and right sides of the grid 221 correspond to each other. The filter screen 222 is provided on the grid 221 and covers the hollow portion 2211. The left and right sides of the grid 221 are respectively provided in each slide 213. The roller 23 cooperates with the grid 221 to drive the filter screen 22 to reciprocate along the slide 213. When the frame 221 slides back and forth between the first arc segment 2131a and the second arc segment 2132a, the edges on both sides of the frame 221 can undergo elastic deformation along the notch 2214, increasing the inward force of the frame 221, thereby improving the overall softness of the filter screen 22 and reducing the sliding resistance of the filter screen 22, so that the filter screen 22 can slide back and forth more smoothly between the first arc segment 2131a and the second arc segment 2132a.

[0086] In order to ensure the smoothness of the filter screen 22 sliding back and forth between the first arc segment 2131a and the second arc segment 2132a, the frame 221 is made of soft plastic through injection molding. At the same time, during the injection molding process, the filter screen 222 is attached to the frame 221 to form an integrated structure. The injection molding process is used to form an integrated structure with the frame 221 and the filter screen 222, thereby improving the overall firmness of the filter screen 22.

[0087] Multiple first support bars 2215 are provided within the hollow portion 2211. The ends of each first support bar 2215 are connected to the left and right sides of the hollow portion 2211, respectively. The positions of the multiple first support bars 2215 correspond one-to-one with the positions of the respective notches 2214 on the flange 2213. These multiple first support bars 2215 enhance the overall strength of the grid 221 and prevent the filter screen 222 within the hollow portion 2211 from bending or collapsing, thereby ensuring the structural stability of the filter screen 22. The rear side surfaces of the first support bars 2215 are either curved or flat.

[0088] A second support bar 2216 is provided within the hollow portion 2211. Its ends are connected to the upper and lower sides of the hollow portion 2211, respectively. A plurality of support protrusions 2216a are spaced apart in the vertical direction on the rear side of the second support bar 2216. Multiple first support bars 2215 are connected to the second support bar 2216. There are multiple second support bars 2216, spaced apart in the left-right direction. Each second support bar 2216 is perpendicular to each first support bar 2215, dividing the hollow portion 2211 into a plurality of square-shaped openings. When the roller 23 drives the filter screen 22 to reciprocate along the slide 213, the outer peripheral wall of the rolling roller 23 abuts against the support protrusions 2216a, thereby supporting the center of the filter screen 22, preventing it from bending or collapsing and ensuring the stability of the filter screen 22 as it reciprocates along the slide 213.

[0089] The first support bars 2215 and the second support bars 2216 are made of soft plastics, and the grid 221, the plurality of first support bars 2215 and the second support bars 2216 are formed into an integral part through an injection molding process, which has high manufacturing efficiency and low cost.

[0090] The flange 2213 is provided with a plurality of reinforcing teeth 2217 arranged in sequence along the up and down directions. The positions of the plurality of reinforcing teeth 2217 correspond one-to-one to the positions of the teeth on the rack portion 2212. The plurality of reinforcing teeth 2217 are connected one-to-one to each tooth on the rack portion 2212, thereby increasing the contact area between the frame 221 and the roller 23 and improving the stability of the movement of the filter screen 22.

[0091] Insertion protrusions 2218 are respectively provided on the upper and lower sides of the rear side surface of the frame 221. The insertion protrusions 2218 extend outward to form a sharp portion protruding from the edge of the frame 221. The thickness of the sharp portion is relatively small, which reduces the thickness of the upper and lower ends of the frame 221, making it easier for the upper or lower side of the filter screen 22 to be inserted into the first slide groove 2131, thereby reducing the difficulty of assembling the filter screen 22 in the slide 213.

[0092] Please refer to Figure 6-Figure 13 The roller 23 includes a second rotating shaft 231, a cylinder 232 and two gears 233. The two ends of the second rotating shaft 231 are respectively rotatably arranged on the left and right sides of the bracket 21. The cylinder 232 is hollow inside and has openings at both ends. The cross street surface of the cylinder 232 is circular. The outer peripheral wall of the cylinder 232 abuts against the support protrusion 2216a of the filter screen 22 to improve the stability of the movement of the filter screen 22. The cylinder 232 is sleeved on the second rotating shaft 231 and rotates synchronously with the second rotating shaft 231.
