Description

Technical Field

[0001] This application relates to the technical field of air conditioning equipment, and particularly to an air conditioner. Background Art

[0002] An air conditioner, that is, an air regulator, refers to a device that uses artificial means to adjust and control parameters such as the temperature, humidity, and flow rate of the air environment in a building or structure. To meet the needs in real life, some air conditioners have a fresh air function, which can transmit outdoor air into the room.

[0003] Currently, with the implementation of the dual-carbon policy and the increasing requirements for the quality of healthy life, the cleaning problem of air conditioner filters has gradually been put on the agenda. If the air conditioner filter is not cleaned regularly, a large amount of dust and bacteria will accumulate, which will not only affect the working efficiency of the air conditioner, increase energy consumption, but also may have an impact on human health, such as causing respiratory diseases. The traditional cleaning method of air conditioner filters requires manual cleaning at regular intervals, which is time-consuming and laborious, and the cleaning effect cannot be guaranteed. The self-cleaning technology of air conditioner filters can realize the automatic cleaning of the filter, greatly improving the cleaning efficiency, saving human resources, and also extending the service life of the air conditioner. Therefore, the self-cleaning project of air conditioner filters is an inevitable trend in the industry development.

[0004] The current solution in the industry is to place the air conditioner cleaning device inside the panel, and the device for cleaning the filter is often relatively large, occupying space and affecting the overall appearance of the machine, especially in the thickness direction of the machine. The thickness of the previous self-cleaning machines was very thick, and the appearance ratio was not beautiful; moreover, the cleaning device has a complex structure, poor reliability and high cost; the cleaning effect is poor. Summary of the Utility Model

[0005] This utility model solves at least one of the technical problems in the related technologies to a certain extent.

[0006] For this reason, this application aims to provide an air conditioner. The first driving component drives the first rotating cylinder and the second rotating cylinder to rotate, and the dirty part of the filter is wound onto the first rotating cylinder. When winding, the filter being wound onto the first rotating cylinder is cleaned by a brush. The second rotating cylinder is located obliquely below the first rotating cylinder. While avoiding self-interference of the filter, compared with the horizontal arrangement of the first rotating cylinder and the second rotating cylinder, the horizontal distance between the first rotating cylinder and the second rotating cylinder can be shortened. Compared with the vertical interval arrangement of the first rotating cylinder and the second rotating cylinder, the vertical distance between the first rotating cylinder and the second rotating cylinder can be shortened. Minimize the size of the cleaning module along the height and length directions of the housing as much as possible, so as to reduce the overall length and height of the air conditioner and improve the user experience. The brush is arranged on the side of the first rotating cylinder, reducing the occupation of the height direction of the housing and not affecting the structural arrangement below the cleaning module.

[0007] To achieve the above object, the utility model provides an air conditioner, comprising:

[0016] A brush disposed on one side of the first rotating cylinder away from the indoor heat exchanger; the brush is used to contact and clean the filter screen on the first rotating cylinder;

[0017] A first driving assembly for driving the first rotating cylinder and the second rotating cylinder to rotate;

[0018] The first driving assembly drives the first rotating cylinder and the second rotating cylinder to rotate, so as to realize the winding or unwinding of the filter screen on the first rotating cylinder, and the brush cleans the filter screen on the first rotating cylinder.

[0019] In the technical solution, the first driving component drives the first rotating cylinder and the second rotating cylinder to rotate, and the dirty part of the filter screen is wound on the first rotating cylinder. When winding, the filter screen being wound on the first rotating cylinder is cleaned by a brush. The second rotating cylinder is located obliquely below the first rotating cylinder. While avoiding self-interference of the filter screen, compared with the horizontal arrangement of the first rotating cylinder and the second rotating cylinder, the horizontal distance between the first rotating cylinder and the second rotating cylinder can be shortened. Compared with the vertical interval arrangement of the first rotating cylinder and the second rotating cylinder, the vertical distance between the first rotating cylinder and the second rotating cylinder can be shortened. The size of the cleaning module along the height and length directions of the housing is minimized as much as possible, so as to reduce the length and height of the overall air conditioner and improve the user experience. The brush is arranged on the side of the first rotating cylinder, reducing the occupation of the height direction of the housing and not affecting the structural arrangement below the cleaning module.

[0020] In some embodiments of the present application, the connection line between the center point of the first rotating cylinder and the center point of the second rotating cylinder is used as a reference line; the minimum included angle between the reference line and the length direction of the housing is 45°.

[0021] In the technical solution, through this design, the first rotating cylinder and the second rotating cylinder occupy the same space in the height direction and the length direction of the housing. The occupation of the internal space of the housing is balanced.

[0022] In some embodiments of the present application, the radius of the filter screen wound on the first rotating cylinder is a; the radius of the filter screen wound on the second rotating cylinder is b; the shortest distance between the axis of the first rotating cylinder and the axis of the second rotating cylinder is c;

[0023] Satisfy, a + b < c.

[0024] In the technical solution, through this design, the possibility of interference between the filter screen on the first rotating cylinder and the filter screen on the second rotating cylinder is avoided.

[0025] In some embodiments of the present application, the first driving component includes:

[0026] A first gear, the first gear is coaxially connected to the first rotating cylinder;

[0027] A second gear, the second gear is coaxially connected to the second rotating cylinder; the second gear meshes with the first gear;

[0028] A first motor, the first motor is arranged on the housing; the first motor is used to drive the first gear or the second gear to rotate.

[0029] In the technical solution, the first motor is used to synchronously rotate the first gear and the second gear, so as to realize the synchronous rotation of the first rotating cylinder and the second rotating cylinder. When the first end of the filter screen is wound by the first rotating cylinder, the second end is unwound by the second rotating cylinder, so as to realize the overall movement of the filter screen, and the brush can clean the filter screen. After the cleaning is completed, the second rotating cylinder winds the second end of the filter screen, and the first rotating cylinder unwinds the filter screen, so that the cleaned filter screen is located at the air inlet of the air conditioner again, thereby completing the entire filter screen cleaning process.

[0030] In some embodiments of the present application, the first driving assembly further includes a plurality of first transmission gears meshing in sequence, and the first transmission gear at one end is connected to the output shaft of the first motor; the first transmission gear at the other end meshes with the first gear or the second gear.

[0031] In the technical solution, through the arrangement of the first transmission gear, the rotation speeds of the first gear and the second gear can be adjusted by using the transmission ratio between the gears. There is no need to separately select a motor with a low rotation speed to meet the use requirements. Moreover, the first motor can be not arranged at the ends of the first rotating cylinder and the second rotating cylinder, and the first motor can be arranged on the side of the first rotating cylinder or the second rotating cylinder, so as to reduce the occupation of the distance in the front-back direction of the housing.

[0032] In some embodiments of the present application, a dust collection box is detachably connected to the bottom of the accommodation cavity.

[0033] In the technical solution, the cleaned dust falls into the dust collection box to realize the collection of the dust. It is convenient for manual cleaning of the dust.

[0034] In some embodiments of the present application, a cleaning part is arranged inside the dust collection box below the brush;

[0035] The air conditioner further includes a second driving assembly, and the second driving assembly is used to drive the brush to flip and contact the cleaning part.

[0036] In the technical solution, the second driving assembly drives the brush to flip and contact the cleaning part to clean the dust on the brush, realizing the self-cleaning function of the brush and ensuring the long-term cleaning effect of the brush on the filter screen.

[0037] In some embodiments of the present application, a rotating rod parallel to the first rotating cylinder is arranged on the side of the first rotating cylinder away from the indoor heat exchanger, and the second driving assembly is used to drive the rotating rod to rotate;

[0038] The brush is arranged on the rotating rod; an elastic member is arranged between the brush and the rotating rod, and the brush can move in the direction close to the rotating rod.

[0039] In the technical solution, when the filter screen is wound on the first rotating cylinder, the diameter of the filter screen wrapped around the first rotating cylinder gradually increases. When the first rotating cylinder unwinds the filter screen, the diameter of the filter screen on the first rotating cylinder gradually decreases. Therefore, the brush may be under greater pressure or may not be able to contact the filter screen. In this application, when the diameter of the filter screen on the first rotating cylinder increases, the elastic member is compressed, and by setting the elastic member, the brush always abuts against the filter screen, improving the cleaning effect.

[0043] In the technical solution, by setting the second transmission gears, the rotation speed of the third gear can be adjusted using the transmission ratio between the gears. There is no need to separately select a low-speed motor to meet the usage requirements. Moreover, the second motor can be not arranged at the end of the rotating rod. The second motor can be arranged on the side of the first rotating cylinder or the second rotating cylinder, thereby reducing the distance occupied in the front-back direction of the housing.

[0048] A filter screen, which is arranged at the air conditioner air inlet and is used for filtering impurities in the air entering the air conditioner air inlet; the two ends of the filter screen are respectively a first end and a second end;

[0049] A receiving cavity is arranged at one end of the housing along its length direction;

[0050] A cleaning module, which is arranged in the receiving cavity; the cleaning module includes:

[0051] A first rotating cylinder, which rotates in the receiving cavity, and the first end of the filter screen is wound around the first rotating cylinder;

[0052] A second rotating cylinder, which rotates within the accommodation cavity, is disposed on a side of the first rotating cylinder facing the indoor heat exchanger; and the second rotating cylinder is located below the first rotating cylinder;

[0053] A brush is disposed below the first rotating cylinder; the brush is used to contact and clean the filter screen on the first rotating cylinder;

[0054] A first driving assembly is used to drive the first rotating cylinder and the second rotating cylinder to rotate;

[0055] The first driving assembly drives the first rotating cylinder and the second rotating cylinder to rotate, so as to realize the winding or unwinding of the filter screen on the first rotating cylinder, and the brush cleans the filter screen on the first rotating cylinder.

[0056] In the technical solution, the first driving assembly drives the first rotating cylinder and the second rotating cylinder to rotate, winds the dirty part of the filter screen onto the first rotating cylinder, and cleans the filter screen being wound on the first rotating cylinder through the brush during winding. The second rotating cylinder is located obliquely below the first rotating cylinder. While avoiding self-interference of the filter screen, compared with the horizontal arrangement of the first rotating cylinder and the second rotating cylinder, the horizontal distance between the first rotating cylinder and the second rotating cylinder can be shortened. Compared with the vertical interval arrangement of the first rotating cylinder and the second rotating cylinder, the vertical distance between the first rotating cylinder and the second rotating cylinder can be shortened. As much as possible, the dimensions of the cleaning module along the height and length directions of the housing are reduced, so as to reduce the length and height of the overall air conditioner and improve the user experience. The brush is disposed below the first rotating cylinder, shortening the occupation of the length direction of the housing.

[0078] Next, the present utility model will be specifically described by way of exemplary embodiments. However, it should be understood that, without further recitation, elements, structures, and features in one embodiment may also be beneficially incorporated into other embodiments.

[0079] In this application, the air conditioner includes an outdoor unit and an indoor unit. Among them, a compressor, an outdoor heat exchanger, and an outdoor fan are provided inside the outdoor unit. An indoor heat exchanger and an indoor fan are provided inside the indoor unit. Heat exchange is achieved by using the outdoor heat exchanger and the indoor heat exchanger as an evaporator and a condenser respectively. The indoor fan outputs the air that has exchanged heat through the indoor heat exchanger to the room to achieve cooling or heating of the room.

[0080] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0081] Please refer to all the drawings. In a schematic embodiment of the air conditioner of the present utility model, the air conditioner includes: a housing 100, and an air conditioner air inlet is provided at the top of the housing 100. The air conditioner may further include an indoor heat exchanger 200, and the indoor heat exchanger 200 is disposed inside the housing 100. The indoor heat exchanger 200 can be made of a metal with good heat exchange capacity, corrosion resistance, and rust prevention performance, and includes a series of pipelines and fins. Heat is exchanged between the refrigerant flowing in the pipelines and the fins, and then heat is exchanged between the indoor air and the fins to achieve refrigeration or heating.

[0082] The air conditioner may further include an indoor fan, and the indoor fan is disposed inside the housing 100. The indoor fan usually adopts a cross-flow fan and has a long strip-shaped structure. It and the indoor air inlet are located on two sides of the indoor heat exchanger 200 respectively. The indoor fan introduces indoor air from the indoor air inlet into the housing 100 and passes through the indoor heat exchanger.

[0083] An air conditioner air outlet may also be provided on the housing 100. Under the action of the indoor fan, the air flow is input into the housing 100 through the air conditioner air inlet, and after heat exchange through the indoor heat exchanger 200, it is input into the room through the air conditioner air outlet.

[0084] The air conditioner may further include a filter screen 300, and the filter screen 300 is disposed at the air conditioner air inlet and is used to filter impurities in the air entering the air conditioner air inlet. The two ends of the filter screen 300 are the first end and the second end respectively. The filter screen 300 can be designed with a borderless structure, making it have the flexible characteristic of being retractable. This design makes the filter screen more flexible and convenient to use during the process.

[0085] Specifically, the filter screen 300 can be designed in a long strip shape, and the two ends in its length direction are respectively set as the first end and the second end for winding. Such a design not only facilitates the installation and disassembly of the filter screen, but also enables the filter screen to be adjusted according to actual needs during use, thus better meeting the usage requirements in different scenarios. In addition, this long strip shape design also makes the winding process of the filter screen smoother, avoiding the problem of difficult winding caused by the excessive length of the filter screen.

[0086] At one end of the housing 100 along its length direction, a receiving cavity 101 is provided. By configuring a receiving cavity 101 inside the housing 100 to specifically accommodate internal specific components and arranging the receiving cavity 101 along the length direction of the housing 100, the excessive height of the housing can be prevented, thereby saving space and maintaining the aesthetic appearance.

[0087] The air conditioner can also include a cleaning module, which is arranged in the receiving cavity 101. A dedicated cleaning module is built into the air conditioner to perform specific cleaning tasks. By centrally arranging the cleaning module in a specific receiving cavity 101, it is ensured that the cleaning module can work efficiently. The cleaning module can be conveniently maintained and replaced, and at the same time, the cleanliness and normal operation of other components inside the air conditioner are ensured.

[0088] The cleaning module can include a first rotating cylinder 400, which rotates in the receiving cavity 101, and the first end of the filter screen 300 is wound around the first rotating cylinder 400.

[0089] The cleaning module can also include a second rotating cylinder 500, which rotates in the receiving cavity 101. The second rotating cylinder 500 is arranged on the side of the first rotating cylinder 400 facing the indoor heat exchanger 200, and the second rotating cylinder 500 is located below the first rotating cylinder 400.

[0090] The air conditioner can also include a brush 600, which is arranged on the side of the first rotating cylinder 400 away from the indoor heat exchanger 200; the brush 600 is used to contact and clean the filter screen 300 on the first rotating cylinder 400.

[0091] The air conditioner can also include a first driving component 800, which is used to drive the first rotating cylinder 400 and the second rotating cylinder 500 to rotate.

[0092] The air conditioner can also include that the first driving component 800 drives the first rotating cylinder 400 and the second rotating cylinder 500 to rotate, realizes the winding or unwinding of the filter screen 300 on the first rotating cylinder 400, and the brush 600 cleans the filter screen 300 on the first rotating cylinder 400.

[0093] The first driving component 800 drives the first rotating cylinder 400 and the second rotating cylinder 500 to rotate, winding the dirty part of the filter screen 300 onto the first rotating cylinder 400. When winding, the filter screen 300 being wound on the first rotating cylinder 400 is cleaned by the brush 600.

[0094] The second rotating cylinder 500 is located diagonally below the first rotating cylinder 400. While avoiding self-interference of the filter screen 300, compared with the horizontal arrangement of the first rotating cylinder 400 and the second rotating cylinder 500, the horizontal distance between the first rotating cylinder 400 and the second rotating cylinder 500 can be shortened. Compared with the vertical interval arrangement of the first rotating cylinder 400 and the second rotating cylinder 500, the vertical distance between the first rotating cylinder 400 and the second rotating cylinder 500 can be shortened. As much as possible, the dimensions of the cleaning module along the height and length directions of the housing 100 are reduced, so as to reduce the length and height of the air conditioner as a whole and improve the user experience.

[0095] The brush 600 is arranged on the side of the first rotating cylinder 400, reducing the occupation of the height direction of the housing 100 and not affecting the structural arrangement below the cleaning module.

[0096] In some embodiments, the line connecting the center points of the first rotating cylinder 400 and the second rotating cylinder 500 is used as a reference line. In some embodiments, the minimum included angle between the reference line and the length direction of the housing 100 is greater than 0°.

[0097] In some embodiments, the minimum included angle between the reference line and the length direction of the housing 100 is less than 90°. This ensures that the second rotating cylinder 500 is located diagonally below the first rotating cylinder 400.

[0098] In some embodiments, the minimum included angle between the reference line and the length direction of the housing 100 is 45°. Through this design, the first rotating cylinder 400 and the second rotating cylinder 500 occupy the same space in the height direction and the length direction of the housing 100. The occupation of the internal space of the housing 100 is balanced.

[0099] In some embodiments, the radius of the filter screen 300 wound on the first rotating cylinder 400 is a; the radius of the filter screen 300 wound on the second rotating cylinder 500 is b; the shortest distance between the axis of the first rotating cylinder 400 and the axis of the second rotating cylinder 500 is c; and a + b < c. Through this design, the possibility of interference between the filter screen 300 on the first rotating cylinder 400 and the filter screen 300 on the second rotating cylinder 500 is avoided.

[0100] In some embodiments, after the air conditioner is installed, the length direction of the housing 100 is horizontally arranged.

[0101] In some embodiments, the accommodating cavity 101 is located at one end of the indoor heat exchanger 200 in the length direction. By arranging the accommodating cavity 101 at one end of the indoor heat exchanger 200, components such as the electronic control box of the air conditioner indoor unit are arranged at both ends of the indoor heat exchanger 200 in the housing 100, so as to achieve the best space utilization and functional layout.

[0102] In addition, the accommodating cavity 101 can also be located at one end of the indoor fan in the length direction. Such a design not only improves the compactness of the device, but also ensures the effective connection and coordinated operation between various components, thereby enhancing the overall operating efficiency and reliability.

[0103] In some embodiments, the filter screen 300 is arranged in a folded manner. Specifically, the filter screen 300 has an upper filter screen and a lower filter screen that do not interfere with each other. The upper filter screen is mainly used to achieve the filtering function, and the lower filter screen moves to the upper layer to temporarily replace and maintain the filtering performance when the upper filter screen is cleaned.

[0104] In another embodiment, the filter screen 300 is arranged in a stacked manner. The filter screen 300 can also be multi-layered, which can achieve a better filtering effect. Through this stacked arrangement, the filter screen 300 can more effectively capture and separate impurities and particles, thereby improving the filtering efficiency and accuracy. This multi-layer stacked arrangement not only increases the filtering area, but also makes the filter screen 300 have higher stability and durability when dealing with a large amount of fluid.

[0105] In some embodiments, after the filter screen 300 is folded or stacked, it is divided into upper and lower layers. The upper layer is close to the air inlet of the air conditioner, and the lower layer is close to the indoor heat exchanger 200. The end of the upper layer of the filter screen 300 is the first end, and the end of the lower layer of the filter screen 300 is the second end.

[0106] In some embodiments, the axis of the first rotating cylinder 400 is parallel to the axis of the second rotating cylinder 500. By arranging the first rotating cylinder 400 and the second rotating cylinder 500 in parallel, the filter screen 300 can be kept flat and move smoothly when being wound and unwound, ensuring the filtering and cleaning effects.

[0107] In some embodiments, the axis of the first rotating cylinder 400 is perpendicular to the length direction of the housing 100. Arranging the first rotating cylinder 400 in the housing 100 in this way can make the filter screen 300 keep flat and aligned when being wound or unwound on the first rotating cylinder 400, ensuring the stability and reliability of the filter screen during use. This vertical setting method also helps to reduce space occupation and makes the overall structure more compact.

[0108] In some embodiments, the axis of the first rotating cylinder 400 is arranged horizontally. By arranging the first rotating cylinder 400 horizontally,

[0109] Reduce the influence of the gravity direction of the filter screen 300 during winding and unwinding, effectively avoid the occurrence of wrinkles or misalignment of the filter screen 300 during the winding and unwinding process, thereby ensuring the service life and filtration effect of the filter screen 300.

[0110] In some embodiments, the length direction of the brush 600 is the same as the length direction of the first rotating cylinder 400.

[0111] In some embodiments, the diameters of the first rotating cylinder 400 and the second rotating cylinder 500 are the same; the rotation speeds of the first rotating cylinder 400 and the second rotating cylinder 500 are the same and the rotation directions are opposite. Through this solution, it is ensured that the areas at both ends of the filter screen 300 are the same when the filter screen 300 is wound and unwound, ensuring that the filter screen 300 can be smoothly supported at the air inlet of the air conditioner at any time. Ensure that it can filter the air entering the air inlet of the air conditioner.

[0112] In some embodiments, the diameters of the first rotating cylinder 400 and the second rotating cylinder 500 are different, but the rotation speeds of the first rotating cylinder 400 and the second rotating cylinder 500 are different. Ensure that the amounts of winding and unwinding on the first rotating cylinder 400 and the second rotating cylinder are the same.

[0113] In some embodiments, the first driving assembly 800 includes a first motor 801, and the first motor 801 is disposed on the housing 100. The first motor 801 drives the first rotating cylinder 400 to rotate. The first motor 801 can be disposed in the accommodation cavity 101, and the first rotating cylinder 400 is driven to rotate by the first motor 801. Concentrating the first motor 801 directly with the first rotating cylinder 400 and the second rotating cylinder 500 in the accommodation cavity 101 can make the structure of the cleaning module more compact and occupy less space.

[0114] In some embodiments, the output shaft of the first motor 801 is coaxially connected to one end of the first rotating cylinder 400. The first motor 801 can drive the second rotating cylinder 500 to rotate. The output shaft of the first motor 801 is coaxially connected to one end of the second rotating cylinder 500. The first driving assembly 800 includes a first gear 802, and the first gear 802 is coaxially connected to the first rotating cylinder 400.

[0115] The first driving assembly 800 includes a second gear 803, and the second gear 803 is coaxially connected to the second rotating cylinder 500; the second gear 803 meshes with the first gear 802. Driving one of the rotating cylinders to rotate, the other rotating cylinder will also rotate synchronously, and multiple motors are not required.

[0116] The first motor 801 can directly drive the first gear 802 to rotate. In addition, the first motor 801 can also directly drive the second gear 803 to rotate.

[0117] The first motor 801 synchronously rotates the first gear 802 and the second gear 803 to achieve synchronous rotation of the first rotating cylinder 400 and the second rotating cylinder 500. When the first end of the filter screen 300 is wound by the first rotating cylinder 400, the second end is unwound by the second rotating cylinder 500 to achieve the overall movement of the filter screen 300. The brush 600 can clean the filter screen 300. After the cleaning is completed, the second rotating cylinder 500 winds the second end of the filter screen 300, and the first rotating cylinder 400 unwinds the filter screen 300 so that the cleaned filter screen 300 is located at the air inlet of the air conditioner again, thus completing the entire cleaning process of the filter screen 300.

[0118] In some embodiments, the first driving assembly 800 further includes a plurality of first transmission gears 804 that are sequentially engaged. The first transmission gear 804 at one end is connected to the output shaft of the first motor 801; the first transmission gear 804 at the other end is engaged with the first gear 802 or the second gear 803.

[0119] By providing the first transmission gear 804, the rotation speeds of the first gear 802 and the second gear 803 can be adjusted using the transmission ratio between the gears. There is no need to separately select a motor with a low rotation speed to meet the usage requirements. Moreover, the first motor 801 may not be disposed at the ends of the first rotating cylinder 400 and the second rotating cylinder 500. The first motor 801 may be disposed on the side of the first rotating cylinder 400 or the second rotating cylinder 500, thereby reducing the distance occupied in the front-rear direction of the housing 100.

[0120] In some embodiments, there are two first transmission gears 804, and the two first transmission gears 804 are respectively gear a and gear b. Among them, gear a and gear b are engaged with each other. Gear b can be engaged with the first gear 802 or the second gear 803. Gear a is connected to the first motor 801. The first motor 801 drives gear a to rotate, and the rotation of the first gear 802 and the second gear 803 is achieved through the transmission of gear b, thereby achieving the rotation of the first rotating cylinder 400 and the second rotating cylinder.

[0121] In some embodiments, a dust collection box 120 is detachably connected to the bottom of the accommodation cavity 101. The cleaned dust falls into the dust collection box 120 to achieve the collection of the dust. It is convenient for manual cleaning of the dust.

[0122] In some embodiments, a cleaning part 700 is provided inside the dust collection box 120 below the brush 600. By contacting the brush 600 with the cleaning part 700, the cleaning of the brush 600 is realized. The air conditioner further includes a second driving component 900, and the second driving component 900 is used to drive the brush 600 to flip and repeatedly contact the cleaning part 700 to achieve the cleaning of the brush 600. By driving the brush 600 to flip and contact the cleaning part 700 through the second driving component 900, the dust on the brush 600 is cleaned, realizing the self-cleaning function of the brush 600 and ensuring the long-term cleaning effect of the brush 600 on the filter screen 300.

[0123] In some embodiments, a rotating rod 610 parallel to the first rotating cylinder 400 is provided on one side of the first rotating cylinder 400 away from the indoor heat exchanger 200, and the second driving component 900 is used to drive the rotating rod 610 to rotate; the brush 600 is arranged on the rotating rod 610.

[0124] In some embodiments, an elastic member 620 is provided between the brush 600 and the rotating rod 610, and the brush 600 can move in a direction close to the rotating rod 610.

[0125] Further, the rotating rod 610 is located on one side of the first rotating cylinder 400 away from the indoor heat exchanger 200 inside the accommodating cavity 101. The brush 600 is slidably connected to the rotating rod 610 along the radial direction of the rotating rod 610. The elastic member 620 is used to push the brush 600 away from the rotating rod 610.

[0126] Because when the filter screen 300 is wound on the first rotating cylinder 400, the diameter of the filter screen 300 wrapped on the first rotating cylinder 400 will gradually increase. And when the first rotating cylinder 400 unwinds the filter screen 300, the diameter of the filter screen 300 on the first rotating cylinder 400 will gradually decrease. Therefore, the brush 600 may be under greater pressure or may not be able to contact the filter screen 300. In this application, when the diameter of the filter screen 300 on the first rotating cylinder 400 becomes larger, the elastic member 620 is compressed, and through the setting of the elastic member 620, the brush 600 always abuts against the filter screen 300, improving the cleaning effect.

[0127] In some embodiments, a chute is formed on the rotating rod 610, and a part of the brush 600 slides in the chute. In this way, the slidable connection between the brush 600 and the rotating rod 610 is realized. The brush 600 slides in the chute along the depth direction of the chute. The depth direction of the chute is arranged along the radial direction of the rotating rod 610. The elastic member 620 is arranged in the chute, and both ends of the elastic member 620 respectively abut against the bottom of the chute and the brush 600.

[0128] In some embodiments, a limiting groove communicating with the sliding groove is formed in the rotating rod 610. A limiting member is provided on the brush 600, and the limiting member is snap-connected and slidably connected in the limiting groove. Through the arrangement of the limiting member and the limiting groove, the separation of the brush 600 from the rotating rod 610 is avoided, and the stability of the structural operation is improved.

[0129] Further, the sliding direction of the limiting member in the limiting groove is the same as the depth direction of the sliding groove. A sliding groove is formed in the brush 600; a part of the rotating rod 610 slides in the sliding groove. An elastic member 620 is arranged in the sliding groove, and two ends of the elastic member 620 respectively abut against the bottom wall of the sliding groove and the rotating rod 610. Through this design, while enabling the brush 600 and the rotating rod 610 to move relative to each other first, it is convenient for the connection between the brush 600 and the rotating rod 610 and for installation.

[0130] In some embodiments, a limiting groove communicating with the sliding groove is formed in the brush 600. A limiting member for sliding in the limiting groove is provided on the rotating rod 610. The limiting member is snap-connected and slidably connected in the limiting groove. Through the arrangement of the limiting member and the limiting groove, the separation of the brush 600 from the rotating rod 610 is avoided, and the stability of the structural operation is improved.

[0131] In some embodiments, the sliding direction of the limiting member in the limiting groove is the same as the depth direction of the sliding groove.

[0132] In some embodiments, the elastic member 620 can be a compression spring. Or, the elastic member 620 can be a rubber block. Or, the elastic member 620 can be a sponge block. As long as it has elasticity and can push the brush 600.

[0133] In some embodiments, the second driving assembly 900 includes a second motor 901, and the second motor 901 directly drives the rotating rod 610 to rotate. The output shaft of the second motor 901 is coaxially connected to one end of the rotating rod 610.

[0134] The second driving assembly 900 further includes a third gear 902 and a plurality of second transmission gears 903 that are sequentially engaged. The third gear 902 is connected to the rotating rod 610. One of the second transmission gears 903 is connected to the output shaft of the second motor 901; the other second transmission gear 903 is engaged with the third gear 902.

[0135] Through the arrangement of the second transmission gears 903, the rotation speed of the third gear 902 can be adjusted by using the transmission ratio between the gears. There is no need to separately select a low-speed motor to meet the usage requirements. Moreover, the second motor 901 can be not arranged at the end of the rotating rod 610. The second motor 901 can be arranged on the side of the first rotating cylinder 400 or the second rotating cylinder 500, so as to reduce the occupancy of the distance in the front-rear direction of the housing 100.

[0136] In some embodiments, there are two second transmission gears 903, namely gear c and gear d. Gear c and gear d mesh with each other, and gear d meshes with the third gear 902. The output shaft of the second motor 901 is coaxially connected to gear c.

The indoor heat exchanger 200 can be made of metal with good heat exchange capacity, corrosion resistance and rust resistance, including a series of pipes and fins, and the refrigerant flows in the pipes to exchange heat with the fins, and then the indoor air exchanges heat with the fins to achieve cooling or heating.

[0138] The air conditioner may further include an indoor fan, which is disposed inside the housing 100. The indoor fan is generally a cross-flow fan, which is in a long strip structure, and the indoor air inlet is located on both sides of the indoor heat exchanger 200, and the indoor fan introduces indoor air from the indoor air inlet into the housing 100 and passes through the indoor heat exchanger.

[0139] The housing 100 may also be provided with an air conditioning outlet. Under the action of the indoor fan, air flow is input into the housing 100 through the air conditioning inlet, and after heat exchange in the indoor heat exchanger 200, air flow is input into the room through the air conditioning outlet.

[0140] The air conditioner may further include a filter 300, which is disposed at the air inlet of the air conditioner and is used to filter impurities in the air entering the air inlet of the air conditioner.

This design makes the filter more flexible and convenient during use.

[0141] Specifically, the filter 300 can be designed to be in the shape of a long strip, with the two ends in the length direction being respectively set as the first end and the second end of the roll-up. Such a design not only facilitates the installation and removal of the filter, but also allows the filter to be adjusted according to actual needs during use, thereby better meeting the use needs of different occasions. In addition, such a long strip design also makes the roll-up process of the filter smoother, avoiding the problem of difficulty in roll-up caused by the filter being too long.

[0142] An accommodating cavity 101 is provided inside the housing 100 along one end of its length. By configuring an accommodating cavity 101 inside the housing 100 to specifically house specific internal components, and arranging the accommodating cavity 101 along the length of the housing 100, the height of the housing can be prevented from being too large, thereby saving space and maintaining the aesthetic appearance.

[0145] The cleaning module includes a second rotating cylinder 500, which rotates in the accommodation cavity 101. The second rotating cylinder 500 is disposed on the side of the first rotating cylinder 400 facing the indoor heat exchanger 200, and the second rotating cylinder 500 is located below the first rotating cylinder 400.

[0146] The cleaning module includes a brush 600, which is disposed below the first rotating cylinder 400; the brush 600 is used to contact and clean the filter screen 300 on the first rotating cylinder 400.

[0147] The air conditioner may further include a first driving assembly 800, which is used to drive the first rotating cylinder 400 and the second rotating cylinder 500 to rotate.

[0148] By driving the first rotating cylinder 400 and the second rotating cylinder 500 to rotate through the first driving assembly 800, the dirty part of the filter screen 300 is wound onto the first rotating cylinder 400. When winding, the brush 600 cleans the filter screen 300 being wound on the first rotating cylinder 400. The second rotating cylinder 500 is located obliquely below the first rotating cylinder 400. While avoiding self-interference of the filter screen 300, compared with the horizontal arrangement of the first rotating cylinder 400 and the second rotating cylinder 500, the horizontal distance between the first rotating cylinder 400 and the second rotating cylinder 500 can be shortened. Compared with the vertical interval arrangement of the first rotating cylinder 400 and the second rotating cylinder 500, the vertical distance between the first rotating cylinder 400 and the second rotating cylinder 500 can be shortened. As much as possible, the dimensions of the cleaning module along the height and length directions of the housing 100 are reduced, so as to reduce the overall length and height of the air conditioner and improve the user experience. The brush 600 is disposed below the first rotating cylinder 400, shortening the occupation of the length direction of the housing 100.
