Description

Technical Field

[0001] The present 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 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 improvement of people's requirements for the quality of healthy life, the cleaning problem of the air conditioner filter 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 the air conditioner filter requires manual cleaning at regular intervals, which is time-consuming and laborious, and the cleaning effect cannot be guaranteed. The self-cleaning technology of the air conditioner filter 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 the air conditioner filter is an inevitable trend in the industry development.

[0004] Currently, the 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 whole 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.

[0078] 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.

[0079] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0080] 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.

[0081] 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 cooling 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, which has a long strip-shaped structure. It and the indoor air inlet are respectively located on two sides of the indoor heat exchanger 200. 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 enters 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 respectively a first end and a second end. 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.

[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, so as to better meet the usage requirements in 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.

[0086] 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 high, thereby saving space and maintaining the aesthetic appearance.

[0087] 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 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 includes a first rotating cylinder 400, and the first rotating cylinder 400 rotates in the receiving cavity 101, and the first end of the filter screen 300 is wound around the first rotating cylinder 400. The cleaning module includes a second rotating cylinder 500, and the second rotating cylinder 500 rotates in the receiving cavity 101, and the second rotating cylinder 500 is located on the side of the first rotating cylinder 400 facing the top of the housing 100; the second end of the filter screen 300 is wound around the second rotating cylinder 500.

[0089] The cleaning module includes a brush 600, and the brush 600 is arranged 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. The cleaning module includes 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.

[0090] 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.

[0091] By driving the first rotating cylinder 400 and the second rotating cylinder 500 to rotate through the first driving component 800, the dirty part of the filter screen 300 is wound onto the first rotating cylinder 400, and when winding, the brush 600 cleans the filter screen 300 being wound on the first rotating cylinder 400.

[0092] The first rotating cylinder 400 is arranged below the second rotating cylinder 500, and the brush 600 is arranged below the first rotating cylinder 400. Therefore, the entire cleaning structure is distributed along the height direction of the housing 100, which reduces the occupation of the interior of the housing 100 along the length direction of the housing 100. The length of the air conditioner as a whole is shortened, improving the user experience.

[0093] 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 electric control box of the air conditioner indoor unit are arranged at both ends of the indoor heat exchanger 200 in the housing 100 to achieve the best space utilization and functional layout.

[0094] 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.

[0095] 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 being cleaned.

[0096] 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.

[0097] In some embodiments, after the filter screen 300 is folded or stacked, it is divided into an upper layer and a lower layer. 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.

[0098] 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.

[0099] In some embodiments, the axis of the first drum 400 is perpendicular to the length direction of the housing 100. Arranging the first drum 400 in the housing 100 in this way enables the filter screen 300 to be kept flat and aligned when being wound or unwound on the first drum 400, ensuring the stability and reliability of the filter screen during use. This vertical arrangement also helps to reduce the space occupied, making the overall structure more compact.

[0100] In some embodiments, the axis of the first drum 400 is horizontally arranged. By horizontally arranging the first drum 400,

[0101] the influence of the gravity direction during the winding and unwinding of the filter screen 300 is reduced, effectively avoiding the situation that the filter screen 300 is wrinkled or misaligned during the winding and unwinding processes, thereby ensuring the service life and filtering effect of the filter screen 300.

[0102] In some embodiments, the first drum 400 and the second drum 500 have the same diameter; the rotation speeds of the first drum 400 and the second drum 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 being wound and unwound, ensuring that the filter screen 300 can be flatly supported at the air inlet of the air conditioner at any time. Ensuring that it can filter the air entering the air inlet of the air conditioner.

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

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

[0105] In some embodiments, the first driving assembly 800 may further include a first gear 802, and the first gear 802 is connected to the first drum 400. The axis of the first gear 802 is collinear with the axis of the first drum 400, and the first gear 802 is located at one end of the first drum 400. The first gear 802 rotates synchronously with the first drum 400. Therefore, when the first gear 802 rotates, the first drum 400 rotates synchronously.

[0106] The first driving component 800 may further include a second gear 803, and the second gear 803 is connected to the second rotating cylinder 500. The axis of the second gear 803 is collinear with the axis of the second rotating cylinder 500, and the second gear 803 is located at one end of the second rotating cylinder 500. The second gear 803 is located at the end of the second rotating cylinder 500 close to the first gear 802. The second gear 803 rotates synchronously with the second rotating cylinder 500. Therefore, when the second gear 803 rotates, the second rotating cylinder 500 rotates synchronously.

[0107] In some embodiments, the second gear 803 meshes with the first gear 802. By setting the gear set structure, the associated transmission of the first rotating cylinder 400 and the second rotating cylinder 500 is realized.

[0108] The first motor 801 is used to drive the first gear 802 to rotate. In addition, the first motor 801 can be used to drive the second gear 803 to rotate.

[0109] By the first motor 801, the first gear 802 and the second gear 803 rotate synchronously 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 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.

[0110] In some embodiments, the output shaft of the first motor 801 can be directly connected to the first gear 802. The first motor 801 directly acts on the first gear 802, that is, directly drives the first rotating cylinder 400, so that the first rotating cylinder 400 is the driving rotating cylinder in the structure, ensuring the stability of winding and unwinding and the cleaning effect when the filter screen 300 is cleaned.

[0111] In some embodiments, the output shaft of the first motor 801 can be directly connected to the second gear 803. The first motor 801 can also directly act on the second gear 803 to make the second rotating cylinder 500 the driving rotating cylinder to drive the first rotating cylinder 400 to rotate.

[0112] In some embodiments, the output shaft of the first motor 801 is connected with a first transmission gear 804, and the first transmission gear 804 meshes with the first gear 802. The first transmission gear 804 and the first gear form a gear set, so that the first motor 801 and the first rotating cylinder 400 perform driving rotation through the gear set, forming an efficient transmission combination. Through the meshing relationship, the transmission ratio can be adjusted to a certain extent, so as to meet the control of the winding and unwinding amounts of the filter screen 300, and the stability and accuracy in the transmission process can be ensured.

[0113] The first transmission gear 804 meshes with the second gear 803. Through the setting of the first transmission gear 804, the rotational 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 low-speed motor to meet the usage requirements.

[0114] In the actual process, the rotational speeds of the first rotating cylinder 400 and the second rotating cylinder 500 should not be too fast. Among the existing motors, there are few motors that meet the required rotational speed and the rotational speed is still relatively fast. Therefore, through the tooth ratio setting of the first transmission gear 804 and the first gear 802 or the second gear 803, the rotational speeds of the first gear 802 and the second gear 803 can be reduced, so that the first rotating cylinder 400 and the second rotating cylinder 500 meet the rotational speed requirements.

[0115] Moreover, this setting can make the position of the motor avoid the end of the first rotating cylinder 400 or the second rotating cylinder 500, facilitating the setting of the position of the motor and reducing the occupation of the internal space of the housing 100.

[0116] In some embodiments, the diameters of the first rotating cylinder 400 and the second rotating cylinder 500 are the same; the transmission ratios of the first gear 802 and the second gear 803 are the same. Through this solution, it is ensured that the areas at both ends 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. It ensures that it can filter the air entering the air inlet of the air conditioner.

[0117] In some embodiments, the first driving assembly 800 may further include two motors, and the two motors drive the first rotating cylinder 400 and the second rotating cylinder 500 to rotate respectively. By driving the rotation with two motors, it can ensure sufficient power for winding and unwinding.

[0118] In some embodiments, a cleaning part 700 is arranged in the accommodation cavity 101. The cleaning part 700 is used to clean the dust on the brush 600. The air conditioner further includes a second driving assembly 900, and the second driving assembly 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 assembly 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.

[0119] In some embodiments, the length direction of the brush 600 is the same as the length direction of the first rotating cylinder 400. In the length directions of the two, being of the same length enables the brush 600 to completely cover the filter screen 300 and ensures the cleaning effect.

[0120] In some embodiments, the rotation axis of the brush 600 is parallel to the axis of the first rotating cylinder 400. Such a design enables the brush 600 and the filter screen 300 on the first rotating cylinder 400 to maintain continuous and complete contact, thereby ensuring the stability of the cleaning effect.

[0121] In some embodiments, the second driving assembly 900 includes a third gear 902, and the third gear 902 is connected to one end of the brush 600 in the length direction. The third gear 902 can be arranged at one end of the brush 600 close to the first gear 802. Or, the third gear 902 can be arranged at one end of the brush 600 far from the first gear 802.

[0122] The second driving assembly 900 may further include a second transmission gear 903, and the second transmission gear 903 meshes with the third gear 902.

[0123] The second driving assembly 900 may further include a second motor 901, and the output shaft of the second motor 901 is connected to the third gear 902. 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, and the transmission ratio between the second transmission gear 903 and the third gear 902 can be changed and can be selected according to requirements.

[0124] In some embodiments, the second driving assembly 900 may only include the second motor 901. The output shaft of the second motor 901 is directly connected to one end of the brush 600. The brush 600 is directly driven by the second motor 901 to flip.

[0125] In some embodiments, the cleaning part 700 can be arranged on one side of the brush 600 in the horizontal direction within the accommodation cavity 101.

[0126] In some embodiments, the cleaning part 700 can be arranged on the side of the brush 600 far from the indoor heat exchanger 200. Or, the cleaning part 700 can be arranged on the side of the brush 600 close to the indoor heat exchanger 200. The cleaning part 700 can be a brush plate. Cleaning is achieved through the repeated contact between the brush 600 and the cleaning part 700.

[0127] In some embodiments, a dust collection box 110 is arranged below the brush 600 within the accommodation cavity 101. The cleaned dust falls into the dust collection box 110, realizing the collection of dust. The dust collection box 110 is detachably arranged. The dust collection box 110 can be manually disassembled to pour out the dust inside the dust collection box 110. It is convenient for maintenance and cleaning.

[0128] In some embodiments, a steering rod is arranged at one end of the housing 100 far from the cleaning module, and the filter screen 300 is wound around the steering rod. Through the steering rod, the folding of the filter screen 300 is realized, thereby enabling the first end and the second end to be located at the same end of the housing 100.

[0129] In some embodiments, the steering rod is disposed at one end of the housing 100 away from the first drum 400. That is, the steering rod and the first drum 400 are located at both ends of the length direction of the air inlet of the air conditioner. The axis of the steering rod is parallel to the axial direction of the first drum 400. The steering rod can be rotated in the housing 100, so as to achieve the stability of the movement of the filter 300 after being wound on the steering rod.

[0130] Please refer to all the drawings. In addition, the present application also provides an air conditioner, which includes a shell 100, and an air conditioning air inlet is opened on the top of the shell 100.

[0131] The air conditioner may further include an indoor heat exchanger 200, which is disposed inside the housing 100. The indoor heat exchanger 200 may be made of metal with good heat exchange capacity, corrosion resistance and rust resistance, and includes a series of pipes and fins, through which 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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, it is possible to prevent the housing from being too tall, thereby saving space and maintaining the aesthetic appearance.

[0137] 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 ensures 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.

[0138] 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. The cleaning module includes a second rotating cylinder 500, which rotates in the receiving cavity 101. The second rotating cylinder 500 is located above the first rotating cylinder 400 and on the side close to the indoor heat exchanger 200. The second end of the filter screen 300 is wound around the second rotating cylinder 500.

[0139] 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.

[0140] The air conditioner may further include a first driving component 800, which is used to drive the first rotating cylinder 400 and the second rotating cylinder 500 to rotate.

[0141] 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.

[0142] By driving the first rotating cylinder 400 and the second rotating cylinder 500 to rotate through the first driving component 800, the dirty part of the filter screen 300 is wound onto the first rotating cylinder 400, and 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 above the first rotating cylinder 400, avoiding the straight-up-and-down interval between the first rotating cylinder 400 and the second rotating cylinder 500, which can shorten the distance distribution of the first rotating cylinder 400 and the second rotating cylinder 500 along the height direction of the housing 100, and minimize the dimensions of the cleaning module in the height and width directions as much as possible, so as to reduce the overall length and height of the air conditioner and improve the user experience.

[0143] In the above solution, since the first end of the upper layer of the filter screen 300 is wound around the first rotating cylinder 400, and the second end of the lower layer of the filter screen 300 is wound around the second rotating cylinder 500. And the second rotating cylinder 500 is closer to the indoor heat exchanger 200 than the first rotating cylinder 400. Therefore, the possibility of interference caused by the two ends of the filter screen 300 coming into contact with each other is also reduced, and the stability of the structure operation is improved.

[0144] Although the embodiments of the present invention 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 invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
