[0022] The present invention will be further described below in conjunction with the embodiments, but is not limited to the contents of the description.

[0023] like Figure 1 As shown, the present invention discloses an air conditioner, such as a duct air conditioner, which includes a shell 10, a filter 20 and a cleaning device 30. The shell 10 has an air outlet 11, preferably a return air outlet; the filter 20 is arranged on the shell 10, and the filter 20 has a working position covering the air outlet 11 and a cleaning position avoiding the air outlet 11. The filter 20 switches between the working position and the cleaning position by moving; the cleaning device 30 is arranged in the shell 10, and the cleaning device 30 is used to clean the filter 20 after the filter 20 reaches the cleaning position.

[0024] In the air conditioner of the present invention, when the filter has been working at the working position for a period of time and a lot of dust has accumulated on the surface, the air intake and the filtering effect are reduced. At this time, the filter is moved to the cleaning position. After arriving at the cleaning position, the cleaning device cleans the filter. After the filter arrives at the cleaning position, it generally stays still. Therefore, the cleaning device has sufficient time to clean the filter, which can avoid the problem of insufficient cleaning time for the filter and greatly improve the cleaning effect.

[0025] In the prior art, when the cleaning device of the air conditioner cleans the filter, the filter needs to be bent to save space. Therefore, the filter is restricted in the selection of materials and can only be made of flexible filters. However, the filtering function of flexible filters is single. As people's living standards improve, their requirements for indoor air quality are gradually increasing. Therefore, simple filtering functions can no longer meet people's needs. Most of the filters on the market with functions such as formaldehyde decomposition and sterilization are hard filters that cannot be bent. It is necessary to solve the problem of how to automatically clean the hard filters.

[0026] In order to solve the above problems, the air conditioner further includes a support structure 40 and a mounting structure 50. The support structure 40 is arranged in the shell 10; the filter 20 is installed on the mounting structure 50, and the mounting structure 50 is movably arranged on the support structure 40. The mounting structure 50 drives the filter 20 to switch between the working position and the cleaning position by movement. During the movement of the mounting structure 50, the filtering surface of the filter 20 is always flat.

[0027] During use, the installation structure can always keep the filtering surface of the filter in a flat state. In other words, during the process of moving the filter from the working position to the cleaning position, or during the process of moving the filter from the cleaning position to the working position, the filter is always in an expanded state, and the filtering surface is flat and will not fold. Therefore, even if a hard filter is used, there is no need to worry about the filter bending during movement, which can greatly expand the range of filter options. Moreover, a flexible filter can also be used, so it is more versatile.

[0028] It should be noted that there are more types of hard filter meshes, for example, they can be injection molded, reinforced, aluminum and other structures, and in terms of function, hard filter meshes can filter finer dust and debris, and the filtering effect is more thorough and obvious.

[0029] Compared with flexible filters, hard filters have the following advantages:

[0030] 1. Compared with the flexible filter, the filtering effect is better, and different types of air purifiers can be added to the hard filter component, such as silver ions, activated carbon, air fresheners, etc.

[0031] 2. The hard filter is not susceptible to damage and is more durable.

[0032] 3. The hard filter is more flexible and convenient when switching automatically.

[0033] like Figure 2 and Figure 3 As shown, further, the support structure 40 includes a first support 41 and a second support 42 connected to each other, and a turning structure 43 is formed at the connection between the first support 41 and the second support 42; the mounting structure 50 includes a mounting frame 51 and a pulley 52, the filter 20 is mounted on the mounting frame 51, and the pulleys 52 are rotatably arranged at both ends of the mounting frame 51; the mounting frame 51 is slidably matched with the support structure 40 through the pulley 52, and the first support 41, the second support 42 and the turning structure 43 are all provided with guide rails for cooperating with the pulley 52.

[0034] During use, when the filter needs to be moved from the working position to the cleaning position, the filter needs to pass through the structure from the first bracket to the second bracket. During the movement of the mounting frame 51 through the turning structure 43, the spacing between the pulleys 52 at both ends of the mounting frame remains unchanged. At the same time, the pulley in the front first passes through the turning structure and reaches the second bracket. At this time, one pulley of the mounting frame is on the first bracket, and the other pulley is on the second bracket. The mounting frame itself is tilted between the first bracket and the second bracket by rotating a certain angle, thereby avoiding bending of the filter. When all the pulleys of the mounting frame are moved to the second bracket, the mounting frame as a whole coincides with the direction of the second bracket. At this time, the filter corresponds to the cleaning device, so that the filter can be cleaned by the cleaning device.

[0035] exist Figure 1 In the embodiment shown, there are two filters 20, and the working positions of the two filters 20 are the same. The cleaning positions of the two filters 20 are respectively located on both sides of the air outlet 11, wherein one filter 20 is located at the working position, and the other filter 20 is located at its corresponding cleaning position, and the two filters 20 can switch positions synchronously by moving. During use, when one filter needs to be cleaned, the filter that needs to be cleaned can be moved from the working position to the cleaning position, and at the same time, the filter at the other cleaning position is synchronously moved to the working position, thereby taking over the previous filter to continue filtering. When the previous filter is cleaned, it waits for the next use, thereby realizing a seamless transition of filter cleaning, which will not affect the filtering effect of the air conditioner.

[0036] It should be noted that the support structure 40 is provided with a guide groove 44, the mounting structure 50 is slidably matched with the guide groove 44, the mounting structure 50 also includes a slider, the slider is connected to the pulley, and further, the air conditioner also includes: a driving structure 60, the driving structure 60 includes a transmission rope 61 and a motor 62, there are two motors 62, the transmission rope is connected between the two motors, and at the same time, the transmission rope 61 is arranged in the guide groove 44, and the slider of the mounting structure 50 is drivingly connected to the transmission rope 61. When in use, the two motors drive the transmission rope forward or backward by rotating forward or reverse at the same time, and the mounting structure 50 moves along the guide groove 44 driven by the transmission rope 61. Due to the provision of the guide groove, the air conditioner of the present invention can be matched with the mounting structure and the transmission rope at the same time, and is a dual-purpose object.

[0037] like Figure 2 As shown, the cleaning device 30 includes a nozzle 31 and a water pump 32. The nozzle 31 is arranged at a position corresponding to the cleaning position of the filter 20. The nozzle 31 is used to clean the filter 20 at the cleaning position. The water pump 32 is connected to the nozzle 31 and is used to supply water to the nozzle 31. The air conditioner of the present invention can spray water on the filter by using the nozzle and the water pump, thereby improving the cleaning effect.

[0038] Furthermore, there are multiple nozzles 31, which are spaced apart, and all nozzles 31 are connected to the water pump 32. The water spraying range of all nozzles 31 covers the filter surface of the filter 20. By providing multiple nozzles, the filter surface of the filter can be cleaned as a whole, thereby improving the cleaning effect.

[0039] In addition, the filter 20 includes a first filter 21 and a second filter 22, the support structure is an inverted U-shaped structure, the support structure also includes a third support 45, the first filter 21 has a first cleaning position, the second filter 22 has a second cleaning position, the setting position of the third support 45 corresponds to the second cleaning position, and the working positions of the first filter 21 and the second filter 22 are the same; the nozzle 31 includes a first nozzle 311 and a second nozzle 312, the setting position of the first nozzle 311 corresponds to the first cleaning position, and the setting position of the second nozzle 312 corresponds to the second cleaning position. Further, the cleaning device 30 also includes a reversing valve 33, the reversing valve 33 has an inlet, a first outlet and a second outlet, the inlet of the reversing valve 33 is connected to the water pump 32, the first outlet of the reversing valve 33 is connected to the first nozzle 311, and the second outlet is connected to the second nozzle 312, and the reversing valve 33 is used to control the direction of water supply by the water pump 32.

[0040] When in use, when the first filter is in the working position, the second filter is in the second cleaning position. At this time, the second nozzle is controlled by the reversing valve to spray water, so that the second filter can be cleaned; when the first filter moves to the first cleaning position, the second filter moves to the working position synchronously. At this time, the first nozzle is controlled by the reversing valve to spray water, so that the first filter can be cleaned. The cleaning device of the present invention can clean the two filters separately by setting the reversing valve, thereby simplifying the overall structure, saving more water, and improving energy efficiency. Moreover, after one filter is cleaned, there is sufficient time to dry it, avoiding working with water and improving the filtering effect.

[0041] It should be noted that Figure 1 The second filter screen 22 includes two sub-filter screens, and the first filter screen also includes two sub-filter screens, and the two sub-filter screens are connected by a connecting rod 80.

[0042] Furthermore, the air conditioner further comprises a water receiving pan 70, which is disposed in the housing 10, and a water inlet of the water pump 32 is connected to the water receiving pan 70. By connecting the water pump in the water receiving pan, condensed water can be used for cleaning, thereby improving the utilization rate of condensed water.
