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, i.e., 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, etc. The traditional cleaning method of air conditioner filters requires manual cleaning at regular intervals, which is both time-consuming and laborious, and the cleaning effect cannot be guaranteed. The self-cleaning technology of air conditioner filters can achieve 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] Currently, the industry solution 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. And because some air conditioners have a fresh air mode, its fresh air module is also set at one end in the length direction of the air conditioner. Therefore, the existing fresh air air conditioners with cleaning devices will affect the setting of the fresh air module, resulting in a larger volume of the air conditioner. Summary of the Utility Model

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

[0006] To this end, 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 brush is arranged between the first rotating cylinder and the second rotating cylinder and is distributed along the length direction of the housing, and it only occupies the space inside the housing near the top. The occupation in the length direction of the housing is reduced, and the fresh air module can be normally set below the cleaning module, ensuring the reasonable internal structure of the air conditioner.

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

[0008] A housing having an air conditioner air inlet at its top;

[0019] 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 by the brush during winding. The brush is disposed between the first rotating cylinder and the second rotating cylinder and is distributed along the length direction of the housing, and it only occupies the space near the top inside the housing. The occupation in the length direction of the housing is reduced, and a fresh air module can be normally disposed below the cleaning module to ensure the reasonable internal structure of the air conditioner.

[0020] In some embodiments of the present application, a dust collection box is detachably connected below the receiving cavity.

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, realizing cooling or heating of the room.

[0078] Hereinafter, the embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0079] 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, including 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 cooling or heating.

[0080] 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, which 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.

[0081] 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.

[0082] 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.

[0083] 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, thereby better meeting the usage requirements of different occasions. 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.

[0084] One end of the interior of the housing 100 along its length direction is provided with a receiving cavity 101. By configuring a receiving cavity 101 inside the housing 100 to specifically place internal specific components, and arranging the receiving cavity 101 along the length direction of the housing 100, it is possible to prevent the housing from being too tall, thereby saving space and maintaining the aesthetic appearance.

[0085] The air conditioner can also include a cleaning module, and the cleaning module 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 ensures that the cleaning module can work efficiently. The cleaning module can be conveniently maintained and replaced, and at the same time, it also ensures the cleanliness and normal operation of other components inside the air conditioner.

[0086] The cleaning module includes a first rotating cylinder 400, and the first rotating cylinder 400 rotates in the receiving cavity 101. The first end of the filter screen 300 is wound around the first rotating cylinder 400. The cleaning module can also include a second rotating cylinder 500, and the second rotating cylinder 500 rotates in the receiving cavity 101. The second rotating cylinder 500 is located on the side of the first rotating cylinder 400 facing the indoor heat exchanger 200 along the length direction of the housing 100; the second end of the filter screen 300 is wound around the second rotating cylinder 500.

[0087] A brush 600 is arranged between the first rotating cylinder 400 and the second rotating cylinder 500; the brush 600 is used to contact and clean the filter screen 300 on the first rotating cylinder 400.

[0088] The air conditioner can also include a first driving component 800, and the first driving component 800 is used to drive the first rotating cylinder 400 and the second rotating cylinder 500 to rotate. The first driving component 800 drives the first rotating cylinder 400 and the second rotating cylinder 500 to rotate, realizing 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.

[0089] Through the above solution, the first driving assembly 800 drives the first rotating cylinder 400 and the second rotating cylinder 500 to rotate, winds the dirty part of the filter screen 300 onto the first rotating cylinder 400, and cleans the filter screen 300 being wound onto the first rotating cylinder 400 through the brush 600 during winding. The brush 600 is arranged between the first rotating cylinder 400 and the second rotating cylinder 500 and is distributed along the length direction of the housing 100, and it only occupies the space near the top inside the housing 100. The occupation of the length direction of the housing 100 is reduced, and the fresh air module can be normally arranged below the cleaning module to ensure the reasonable internal structure of the air conditioner.

[0090] In some embodiments, after the air conditioner is installed, the length direction of the housing 100 is horizontally arranged.

[0091] In some embodiments, the first rotating cylinder 400, the brush 600, and the second rotating cylinder 500 are arranged at intervals along the length direction of the housing 100.

[0092] In some embodiments, the accommodation cavity 101 is located at one end of the indoor heat exchanger 200 in the length direction. By arranging the accommodation cavity 101 at one end of the indoor heat exchanger 200, components such as the electric control box of the indoor unit of the air conditioner are arranged at both ends of the indoor heat exchanger 200 inside the housing 100 to achieve the best space utilization and functional layout.

[0093] In addition, the accommodation 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 equipment but also ensures the effective connection and coordinated operation among various components, thereby enhancing the overall operating efficiency and reliability.

[0094] In some embodiments, the filter screen 300 is folded. 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 replace the upper filter screen temporarily to maintain the filtering performance when the upper filter screen is being cleaned.

[0095] In another embodiment, the filter screen 300 is stacked. 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.

[0096] 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.

[0097] In some embodiments, the axis of the first rotating cylinder 400 is parallel to the axis of the second rotating cylinder 500. The parallel arrangement of the first rotating cylinder 400 and the second rotating cylinder 500 enables the filter screen 300 to be kept flat and move smoothly during winding and unwinding, ensuring the filtering and cleaning effects.

[0098] In some embodiments, the axis of the first rotating cylinder 400 is perpendicular to the length direction of the housing 100. Such an arrangement of the first rotating cylinder 400 within the housing 100 enables the filter screen 300 to be kept flat and aligned when wound or unwound on the first rotating cylinder 400, ensuring the stability and reliability of the filter screen during use. This perpendicular arrangement also helps to reduce space occupancy, making the overall structure more compact.

[0099] In some embodiments, the axis of the first rotating cylinder 400 is horizontally arranged. By arranging the first rotating cylinder 400 horizontally,

[0100] the influence of the gravity direction during winding and unwinding of the filter screen 300 is reduced, effectively avoiding the occurrence of wrinkles or misalignment of the filter screen 300 during winding and unwinding, thereby ensuring the service life and filtering effect of the filter screen 300.

[0101] In some embodiments, the length direction of the brush 600 is the same as the length direction of the first rotating cylinder 400.

[0102] In some embodiments, the diameters of the first rotating cylinder 400 and the second rotating cylinder 500 are the same; the rotating speeds of the first rotating cylinder 400 and the second rotating cylinder 500 are the same and the rotating directions are opposite. Through this solution, it is ensured that the areas at both ends of the filter screen 300 are the same when being wound and unwound, ensuring that the filter screen 300 can be supported flat at the air inlet of the air conditioner at any time. Ensuring that it can filter the air entering through the air inlet of the air conditioner.

[0103] In some embodiments, the diameters of the first rotating cylinder 400 and the second rotating cylinder 500 are different, but the rotating speeds of the first rotating cylinder 400 and the second rotating cylinder 500 are different. Ensuring that the amounts wound and unwound on the first rotating cylinder 400 and the second rotating cylinder are the same.

[0104] In some embodiments, the first driving assembly 800 may include a first motor 801, and the first motor 801 is arranged on the housing 100. The first rotating cylinder 400 is driven to rotate by the first motor 801. The first motor 801 may be arranged in the accommodation cavity 101, and the first rotating cylinder 400 is driven to rotate by the first motor 801. By directly arranging the first motor 801, the first rotating cylinder 400, and the second rotating cylinder 500 in the accommodation cavity 101, the structure of the cleaning module can be made more compact and occupy less space.

[0105] In some embodiments, two first motors 801 may be provided, and the two first motors 801 drive the first drum 400 and the second drum 500 to rotate respectively. In addition, only one first motor 801 is provided. The first driving assembly 800 further includes a first gear 802 and a second gear 803. The first gear 802 is coaxially connected to the first drum 400; the second gear 803 is coaxially connected to the second drum 500; the second gear 803 is in transmission connection with the first gear 802. When the first motor 801 drives the first gear 802 or the second gear 803 to rotate, the synchronous rotation of the first drum 400 and the second drum 500 can be achieved.

[0106] The output shaft of the first motor 801 may be directly coaxially connected to the first gear 802. In addition, the output shaft of the first motor 801 may also be directly coaxially connected to the second gear 803.

[0107] In some embodiments, the first driving assembly 800 further includes a first transmission gear 804, and the first transmission gear 804 is coaxially connected to the output shaft of the first motor 801. The first transmission gear 804 meshes with the first gear 802. The first driving assembly 800 further includes a first transmission gear 804, and the first transmission gear 804 is coaxially connected to the output shaft of the first motor 801. The first transmission gear 804 meshes with the second gear 803.

[0108] A plurality of first transmission gears 804 may be provided, and the plurality of first transmission gears 804 are meshed in sequence, and one of the first transmission gears 804 meshes with the first gear 802 or the second gear 803. The first transmission gear 804 is connected to the first motor 801.

[0109] Through the arrangement of the first transmission gear 804, the rotation speeds of the first gear 802 and the second gear 803 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 usage requirements.

[0110] In actual operation, the rotation speeds of the first drum 400 and the second drum 500 should not be too fast. Among the existing motors, there are few motors that meet the required rotation speed and the rotation speed is still relatively fast. Therefore, by setting the tooth ratio of the first transmission gear 804 and the first gear 802 or the second gear 803, the rotation speeds of the first gear 802 and the second gear 803 can be reduced, so that the first drum 400 and the second drum 500 meet the rotation speed requirements.

[0111] Moreover, this arrangement can enable the position of the motor to avoid the end of the first drum 400 or the second drum 500, facilitating the setting of the position of the motor and reducing the occupation of the internal space of the housing 100.

[0112] In the present application, since the brush 600 is disposed between the first rotating cylinder 400 and the second rotating cylinder 500, the distance between the first rotating cylinder 400 and the second rotating cylinder 500 is relatively large. Therefore, the diameters of the first gear 802 and the second gear 803 are relatively large, which will occupy a relatively large space inside the housing 100.

[0113] For this reason, in some embodiments, a plurality of third transmission gears 805 that are sequentially engaged are disposed between the first gear 802 and the second gear 803, and the third transmission gears 805 at the outermost ends are respectively engaged with the first gear 802 and the second gear 803. In this way, the transmission between the first gear 802 and the second gear 803 is realized.

[0114] In some embodiments, the number of the third transmission gears 805 is an even number. Through this design, it is ensured that the rotation directions of the first rotating cylinder 400 and the second rotating cylinder 500 are opposite. The filter screen 300 can be wound or unwound from above with respect to the first rotating cylinder 400 and the second rotating cylinder 500, and during installation, the installation will not be affected by the position of the filter screen 300.

[0115] In some embodiments, the number of the third transmission gears 805 is two, and the two third transmission gears 805 are respectively engaged with the first gear 802 and the second gear 803, and the two third transmission gears 805 are engaged with each other.

[0116] In some embodiments, the diameters of the two first rotating cylinders 400 are the same, the module and pitch circle diameter of the first gear 802 and the second gear 803 are the same. The module and pitch circle diameter of the plurality of third transmission gears 805 are the same. In this way, it is ensured that the winding amounts of the first rotating cylinder 400 and the second rotating cylinder 500 are the same.

[0117] In some embodiments, the pitch circle diameter of the third transmission gear 805 can be smaller than the pitch circle diameter of the first transmission gear 804.

[0118] In the above content, the first motor 801 is used to synchronously rotate the first gear 802 and the second gear 803, so as to realize the 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, so as to realize the overall movement of the filter screen 300, and 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, thereby completing the entire cleaning process of the filter screen 300.

[0119] In some embodiments, a dust collection box 110 is detachably connected below the accommodation cavity 101. The cleaned dust falls into the dust collection box 110 to realize the collection of the dust. It is convenient for manual cleaning of the dust.

[0120] In some embodiments, the dust collection box 110 and the housing 100 can be connected by snap connection. In addition, the dust collection box 110 and the housing 100 can be connected by a threaded connector. Additionally, the dust collection box 110 can be inserted into the housing 100 to be fixed below the accommodation cavity 101.

[0121] In some embodiments, a cleaning part 700 is arranged inside the dust collection box 110 below the brush 600. 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 contact the cleaning part 700. 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.

[0122] In some embodiments, the cleaning part 700 can be a brush plate. In addition, the cleaning part 700 can also be a comb.

[0123] In some embodiments, a rotating rod 610 is arranged between the first rotating cylinder 400 and the second rotating cylinder 500, 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. By rotating the rotating rod 610, the rotation of the brush 600 can be realized.

[0124] In some embodiments, the axial length direction of the rotating rod 610 is the same as the length direction of the brush 600. That is, the axis of the rotating rod 610 is parallel to the axis of the first rotating cylinder 400.

[0125] In some embodiments, an elastic member 620 is arranged between the brush 600 and the rotating rod 610, and the brush 600 can move towards the direction close to the rotating rod 610. 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 arrangement of the elastic member 620, the brush 600 is always abutted against the filter screen 300, improving the cleaning effect.

[0126] In some embodiments, the elastic member 620 can be a 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.

[0127] In some embodiments, a clamping groove is formed on the rotating rod 610. Part of the brush 600 is slidably connected in the clamping groove. The elastic member 620 is disposed in the clamping groove. The depth direction of the clamping groove is arranged along the radial direction of the rotating rod 610.

[0128] In some embodiments, a clamping groove is formed on the brush 600, a part of the rotating rod 610 slides in the clamping groove, and the elastic member 620 is disposed in the clamping groove. A limiting member is arranged on the rotating rod 610, a limiting groove is arranged on the brush 600, and the limiting member slides in the limiting groove. While ensuring the sliding of the brush 600 and the rotating rod 610, the brush 600 is prevented from disengaging from the clamping groove, or the rotating rod 610 is prevented from disengaging from the clamping groove.

[0129] In some embodiments, the second driving assembly 900 includes a second motor 901 to drive the brush 600 to rotate. The output shaft of the second motor 901 can be directly connected to the rotating rod 610 to achieve the flipping of the brush 600.

[0130] The second driving assembly 900 may further include a third gear 902, and the third gear 902 is connected to the brush 600. Specifically, the third gear 902 is connected to the rotating rod 610.

[0131] The second driving assembly 900 further includes a second transmission gear 903. The output shaft of the second motor 901 is connected to the second transmission gear 903, and the second transmission gear 903 is in transmission connection with the third gear 902. Thereby, the second motor 901 drives the brush 600 to flip.

[0132] In order to avoid that the direct setting of the second motor 901 at the end of the rotating rod 610 increases the size of the air conditioner in the front-rear direction. The second motor 901 is arranged on one side of the first rotating cylinder 400 away from the indoor heat exchanger 200.

[0133] In some embodiments, since the brush 600 is located between the first rotating cylinder 400 and the second rotating cylinder 500. Therefore, the distance between the second motor 901 and the rotating rod 610 is relatively far. For this reason, the number of the second transmission gears 903 can be multiple. The multiple second transmission gears 903 are meshed in sequence. The second transmission gear 903 at the outermost end closest to the second motor 901 is connected to the second motor 901. The second transmission gear 903 at the other end is meshed with the third gear 902.

[0134] In the above solution, through the cooperation of the third gear 902, the second transmission gear 903 and the second motor 901, the flipping control of the brush 600 is realized. The transmission ratio between the second transmission gear 903 and the third gear 902 can be changed and can be selected according to requirements.

[0135] In some embodiments, there are four second transmission gears 903 ; the second motor 901 and the third gear 902 are respectively connected to the two second transmission gears 903 at the end. The second transmission gears 903 are rotatably connected in the housing 100 .

[0136] In some embodiments, a steering rod is provided at one end of the housing 100 away from the cleaning module, and the filter 300 is wound around the steering rod. The steering rod is used to fold the filter 300, so that the first end and the second end are located at the same end of the housing 100.

[0137] In addition, the present application also provides an air conditioner, which includes a housing 100, and an air conditioning air inlet is opened on the top of the housing 100. The air conditioner may also include an indoor heat exchanger 200, and the indoor heat exchanger 200 is arranged inside the housing 100. 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. The two ends of the filter 300 are respectively a first end and a second end. The design of the filter 300 may adopt a frameless structure, so that it has the flexible feature of being retractable. 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] One end of the interior of the housing 100 along its length is provided with a receiving cavity 101. By configuring a receiving cavity 101 inside the housing 100 to specifically accommodate specific internal 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.

[0143] The air conditioner may further include a cleaning module, which is disposed 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, and the cleaning module can be conveniently maintained and replaced. At the same time, the cleanliness and normal operation of other components inside the air conditioner are also ensured.

[0144] The cleaning module includes 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.

[0145] The cleaning module may further include a second rotating cylinder 500, which rotates in the receiving cavity 101. The second rotating cylinder 500 is located on the side of the first rotating cylinder 400 facing the indoor heat exchanger 200 along the length direction of the housing 100; the second end of the filter screen 300 is wound around the second rotating cylinder 500.

[0146] The cleaning module may further include a brush 600, which is disposed on the side of the first rotating cylinder 400 away from the second rotating cylinder 500; 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. The first driving assembly 800 drives the first rotating cylinder 400 and the second rotating cylinder 500 to rotate, realizing 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.

[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 brush 600, the first rotating cylinder 400, and the second rotating cylinder 500 are distributed along the length direction of the housing 100, and they only occupy the space near the top inside the housing 100. The occupation in the length direction of the housing 100 is reduced, and a fresh air module can be normally arranged below the cleaning module, ensuring a reasonable internal structure of the air conditioner.

[0149] In some embodiments, the structural form of the first driving assembly 800 may be the same as the structure mentioned above.

[0150] In this solution, since the brush 600 is close to the side of the first rotating cylinder 400 away from the second rotating cylinder 500, the brush 600 can be arranged closer to the second motor 901, reducing the number of the second transmission gears 903 in the second driving assembly 900.

[0151] Although the embodiments of the present utility model have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present utility model. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present utility model.
