The present application proposes an air conditioner cleaning device.

In the embodiment of the present application, as shown in FIGS. 1 to 5, the air conditioner cleaning device includes:

The filter assembly 10 includes a rotating shaft and a filter movably arranged around the rotating shaft, and at least one end of the rotating shaft is provided with a first driven gear 11;

The roller brush assembly 20 is disposed adjacent to the filter screen, so that the roller brush assembly 20 is used to clean the filter screen in a cleaning mode of an air conditioner, and a rotation axis of the roller brush assembly 20 is provided. There is a second driven gear 21 corresponding to the first driven gear 11;

The transmission gear assembly includes a first transmission gear 31 and a second transmission gear 32 coaxially connected with the first transmission gear 31. The first transmission gear 31 is in transmission mesh with the first driven gear 11. The second transmission gear 32 is in transmission mesh with the second driven gear 21.

In this embodiment, the first driven gear 11 may be provided only at one end of the rotating shaft to reduce the number of power sources and transmission structures and simplify the overall structure of the air conditioner cleaning device. The rotating shaft can be rotated to wind or unwind the filter screen. Specifically, two ends of the rotating shaft can be provided with winding gears, and two sides of the filter screen can be provided with winding racks adapted to the winding gear. The roller brush assembly 20 is arranged in parallel with the rotation axis, and the second driven gear 21 is disposed on an end of the roller brush assembly 20 adjacent to the first driven gear 11. It can be understood that when the rotating shaft rotates to drive the filter screen and the roller brush assembly 20 also rotates, the roller brush assembly 20 will clean the filter screen, and the cleaning method may be brush washing, water spraying, or the like. The first transmission gear 31 and the second transmission gear 32 are coaxially connected. The size of the first transmission gear 31 and the second transmission gear 32 is not limited, and it is only necessary to meet the meshing of the first transmission gear 31 and the first driven gear 11 at the same time. The second transmission gear 32 can mesh with the second driven gear 21. The first transmission gear 31 and the second transmission gear 32 may be connected through a connecting shaft, or may be directly fixed and overlapped. The first transmission gear 31 and the second transmission gear 32 are driven by the same power source, and only one of them needs to be driven, and the other can rotate at the same speed.

The air conditioner cleaning device of the present application engages the first driven gear 11 of the filter assembly 10 and the second driven gear 21 of the roller brush assembly 20 with the first transmission gear 31 and the second transmission gear 32 which are coaxially connected, respectively. Therefore, only one of the first transmission gear 31 or the second transmission gear 32 needs to be driven, and the other can be driven synchronously, so that the rotating shaft and the roller are driven by the first driven gear 11 and the second driven gear 21, respectively. The roller brush assembly 20 is used to clean the filter screen; thus, the filter assembly 10 and the roller brush assembly 20 are driven by the same power source, reducing the number of power sources and transmission mechanisms, and simplifying the overall structure of the air conditioner cleaning device, thereby Reduced the overall cost of the air-conditioning indoor unit.

Further, the roller brush assembly 20 includes a roller and bristles provided on the roller, and the roller is disposed adjacent to a moving track of the filter screen, so that the bristles rotate with the roller. The trajectory of movement through the screen. In this embodiment, the roller can be set away from the rotating shaft, and it only needs to meet the requirement that the filter passes through the roller during the process of unrolling or winding. The roller is provided with bristles. The material of the bristles is not limited. During the rotation of the shaft, the trajectory of the filter screen will be passed. Therefore, the bristles and the filter screen will contact each other during the movement, so the bristles can brush off the dust on the filter screen to achieve the purpose of cleaning the filter screen.

Further, the roller brush assembly 20 is disposed adjacent to the rotating shaft so that a cleaning gap 40 is formed between the roller and the rotating shaft, and the trajectories of the filter screen and the bristles pass through the cleaning gap 40. In this embodiment, the shaft centers of the first transmission gear 31 and the second transmission gear 32 may be perpendicular to the shaft centers of the rotating shaft and the roller. At this time, the first transmission gear 31 and the second transmission gear 32 are bevel gears. The roller is arranged adjacent to the rotating shaft, which can reduce the size of the transmission gear assembly, so that the overall structure of the air conditioner cleaning device is simpler and more compact. It can be understood that the filter screen will pass through the cleaning gap 40 during the winding or stretching process, thereby increasing the contact area between the filter screen and the bristles and improving the cleaning efficiency.

Further, as shown in FIG. 5, the axis centers of the first transmission gear 31 and the second transmission gear 32 are parallel to the axis centers of the rollers and the rotation shafts; the first driven gear 11 projects in the axial direction. The second driven gear 21 is provided, or the second driven gear 21 protrudes from the first driven gear 11 in the axial direction. In the present embodiment, the first driven gear 11 is axially protruded from the second driven gear 21, and the shaft center of the transmission gear assembly is arranged side by side in parallel with the roller and the rotation shaft. At this time, the second driven gear 21 is located at Between the second transmission gear 32 and the rotating shaft, the positional relationship between the transmission gear assembly, the roller brush assembly 20 and the screen assembly 10 can be made more compact, thereby reducing the volume of the air conditioner cleaning device.

The roller brush assembly 20 is at least partially located in the water tank 50. In this embodiment, the first transmission gear 31 is located below the first driven gear 11 and the second transmission gear 32 is located below the second driven gear 21. At this time, the transmission gear assembly is located on one side of the water tank 50. The water tank 50 is used for containing cleaning water to improve the cleaning quality of the filter screen by the bristles.

Further, the transmission ratio i1 of the first transmission gear 31 and the first driven gear 11 is smaller than the transmission ratio i2 of the second transmission gear 32 and the second driven gear 21. In this embodiment, the first transmission gear 31 is larger than the first driven gear 11 and the second transmission gear 32 is larger than the second driven gear 21, so i1 and i2 are both larger than 1, because the first transmission gear 31 and the second transmission The rotation speed of the gear 32 remains the same. Therefore, when i1 is less than i2, the rotation speed of the first driven gear 11 is always smaller than the rotation speed of the second driven gear 21, so that the rotation speed of the rotating shaft is smaller than the rotation speed of the roller, so as to improve the bristles against the filter. The frequency of cleaning at the same location improves the cleaning quality of the filter. It should be noted that if the first transmission gear 31 is smaller than the first driven gear 11 and the second transmission gear 32 is smaller than the second driven gear 21, i1 and i2 are both less than 1, because the first transmission gear 31 and the second transmission The rotation speed of the gear 32 remains the same, at this time i1 should be greater than i2, so that the rotation speed of the first driven gear 11 is always smaller than the rotation speed of the second driven gear 21, so that the rotation speed of the rotating shaft is smaller than the rotation speed of the roller.

Further, as shown in FIG. 1, the air conditioner cleaning device further includes a bracket 60 connected to the rotating shaft, and the filter can be movably laid on the bracket 60. In this embodiment, the rotating shaft is disposed at one end of the bracket 60, and the filter can be deployed along the bracket 60 in a direction away from the rotating shaft, and can also be retracted along the bracket 60 in a direction close to the rotating shaft, so as to improve the filtering or winding process of the filter. In stability.

Further, as shown in FIG. 4, a sidewall of the second transmission gear 32 is fixedly overlapped with a sidewall of the first transmission gear 31. In this embodiment, the second transmission gear 32 is smaller than the first transmission gear 31, and the side wall of the second transmission gear 32 is directly fixed to the side wall of the first transmission gear 31 to reduce the axial size of the transmission gear assembly. To reduce the overall volume of the air conditioner cleaning device. In practical applications, the first transmission gear 31 and the second transmission gear 32 are integrally formed to reduce the processing steps of the transmission gear assembly, reduce the processing cost, and improve production efficiency.

Further, as shown in FIG. 1 to FIG. 5, the air conditioner cleaning device further includes a driving motor 70 and a driving gear 80. The driving gear 80 meshes with the first transmission gear 31 or the second transmission gear 32. An output shaft of the driving motor 70 is connected to the driving gear 80, and the driving motor 70 is located on a side of the driving gear 80 adjacent to the roller brush assembly 20. In this embodiment, the driving gear 80 meshes with the first transmission gear 31 and is located below the first transmission gear 31.

The specific structure of the air-conditioning indoor unit 100 will be described below, and an example will be described in which the air-conditioning indoor unit 100 is horizontally placed. As shown in FIG. 16 to FIG. 18, in an embodiment of the air-conditioning indoor unit 100 of the present application, the air-conditioning indoor unit 100 Machine 100 includes:

A casing 101, which is provided with an air inlet 111 and an air outlet 13;

A blower fan 30 is provided in the casing 101 and is provided with a first airflow inlet and a first airflow outlet. The first airflow inlet is in communication with the air inlet 111. An airflow outlet is in communication with the air outlet 13;

A heat exchanger provided in the casing 101 and located between the air inlet 111 and the first air inlet according to a flow direction of the airflow, the heat exchanger having 101 at two ends arranged in the length direction, one end of the heat exchanger is a refrigerant inlet and outlet end;

Fresh air device 150, which is located in the casing 101 and is located on the side of the end of the heat exchanger facing away from the refrigerant inlet and outlet. The fresh air device 150 is provided with a fresh air inlet 150a and a fresh air outlet. The fresh air outlet is communicated with the room;

Fresh air accessory 160, which is provided in the casing 101, a fresh air duct is formed in the fresh air accessory 160, and one end of the fresh air duct is in communication with the fresh air inlet 150a;

A fresh air duct 170, one end of the fresh air duct 170 is in communication with an end of the fresh air duct facing away from the fresh air inlet 150a, and the other end is in communication with the outdoor.

Specifically, the casing 101 has a substantially rectangular parallelepiped shape, and a length direction thereof is disposed along a horizontal direction. The top position of the casing 101 is provided with an air inlet 111 and a fresh air exhaust port 15, and an air outlet 13 is provided at a position lower than the front of the casing 101. A housing cavity is formed hollow in the casing 101, and is configured to house the air supply fan 30, the heat exchanger, the fresh air device 150, the fresh air fitting 160, the pipeline, and the electronic control element. The blower fan 30 is generally a cross-flow fan, which is fixed in the accommodating cavity of the casing 101, and its axis is set along the length direction of the casing 101. The cross-flow fan has a first air inlet that communicates with the air inlet 111 of the casing 101 and is configured to introduce airflow from the air inlet 111. The cross-flow fan also has a first air outlet that communicates with the air outlet 13 of the casing 101 and is provided as The airflow is blown out from the air outlet 13. The heat exchanger is also fixed in the accommodating cavity of the casing 101, and is transversely separated between the air inlet 111 of the casing 101 and the first air inlet of the cross-flow fan according to the airflow direction, so that the heat introduced from the air inlet 111 Before entering the cross-flow fan from the first airflow inlet, the airflow can pass through the heat exchange effect of the heat exchanger to adjust the temperature of the airflow.

In this way, when the blower fan 30 (cross-flow fan) is running, the indoor air will enter the housing 101 from the air inlet 111 of the cabinet 101, and then pass through the heat exchange effect of the heat exchanger and be removed from The first air inlet enters the blower fan 30. After being accelerated by the blower fan 30, it flows out from the first airflow outlet and flows back to the room from the air outlet 13 of the casing 101. In this way, the indoor air can gradually approach the preset temperature value after continuous heat exchange by the heat exchanger, thereby providing a comfortable indoor environment for the user and improving the quality of life of the user.

Further, the fresh air outlet of the fresh air device 150 communicates with the fresh air exhaust port 15 on the top of the casing 101 (either directly butt connection or through middleware such as pipes), that is, the fresh air outlet of the fresh air device 150 passes through the casing 101 The fresh air exhaust port 15 at the top communicates with the room. When the fresh air device 150 is running, fresh outdoor air will pass through the fresh air duct 170 and the fresh air duct of the fresh air accessories 160 to enter the fresh air device 150 from the fresh air inlet 150a, and then blow out from the fresh air outlet after being accelerated by the centrifugal fan It is blown into the room through the fresh air exhaust port 15 of the cabinet 101, thereby providing continuous and fresh air to the closed room and increasing the oxygen content of the indoor air.

Therefore, when the cooling or heating function of the air-conditioning indoor unit 100 is turned on, even if the user closes the doors and windows in the room, the outdoor air can be introduced into the room through the fresh air device 150 to provide continuous and fresh air to the closed room, thereby increasing The oxygen content of the indoor air improves the quality of the indoor air when the air conditioner is running, thereby preventing air conditioning diseases.

At the same time, the installation of the fresh air fitting 160 is equivalent to adding a stable fresh air between the fresh air inlet 150a of the fresh air device 150 and the pipe escape opening 17 for the refrigerant pipe 90 and the fresh air pipe 170 on the casing 101. In this way, when performing the communication arrangement between the fresh air pipe 170 and the fresh air device 150, it is only necessary to directly fix the end of the fresh air pipe 170 located in the casing 101 to the fresh air fitting 160 and the fresh air fitting 160. The fresh air duct can be connected, which is simple, convenient, and reliable. At the same time, the length of the fresh air pipe 170 inside the air-conditioning indoor unit 100 can be effectively shortened and the cost can be reduced.

At the same time, the volute 10c also forms the air blower 30 together with the air supply wind wheel and the motor. However, at this time, the volute 10c is no longer an independent structure, and it becomes a part of the chassis 10b. In this way, the structure of the air-conditioning indoor unit 100 is optimized, and manufacturing is more convenient.

Further, a surface of the fresh air accessory 160 facing the chassis 10b is in abutting relationship with the chassis 10b. Specifically, the chassis 10b includes a volute 10c, and the surface of the volute 10c facing the fresh air fitting 160 is a curved surface. Accordingly, the surface of the fresh air fitting 160 facing the volute 10c is also a curved surface with two curved surfaces. Fitting settings. In this way, the blower fan 30 can be effectively prevented from colliding with the fresh air fitting 160 due to vibration, thereby effectively avoiding the generation of collision noise.
