[0002] The air inlet of the air conditioner is equipped with a filter, which can prevent dust, hair and other small particles from entering the air conditioner and protect the air conditioner. If the filter is not cleaned for a long time, dust and other foreign matter on the filter will accumulate and block the filter, reduce the air intake, and reduce the heat exchange efficiency of the heat exchanger. Existing air conditioner filters are mostly detachable and manually cleaned, which is troublesome to disassemble and clean. If the filter is not cleaned for a long time, dust will accumulate on the filter, affecting the air intake and reducing the heat exchange efficiency of the heat exchanger.

[0003] The related art discloses an air conditioner with a reversible air outlet direction, which can adapt to the cooling or heating conditions of the air conditioner by switching the air outlet direction of the air outlet, thereby improving the user's comfort.

DETAILED DESCRIPTION

[0039] The filter in the related technology is arranged horizontally inside the air duct of the cabinet, which is suitable for filtering the upward and downward airflow in the vertical air duct of the cabinet (cabinet air conditioner). However, there is a large through space between the filter and the inlet and outlet of the air duct (that is, the air outlet). The filter is not arranged close to the air outlet structure and the horizontally arranged filter causes a large amount of debris (dust, cotton wool, etc.) in the incoming air flow to be filtered and retained on the filter, which requires users to frequently clean the filter.

[0040] Based on the above deficiencies in the related art, combined with reference to Figures 1 to 10As shown, according to an embodiment of the present invention, a filter mechanism is provided, including an upper support member 11, a lower support member 12, and a filter assembly 2, wherein the upper support member 11 and the lower support member 12 are used to be connected to a first air duct 103 of a cabinet air conditioner, and the upper support member 11 is located above the lower support member 12, and the filter assembly 2 is connected between the upper support member 11 and the lower support member 12, and the filter assembly 2 can be moved between a first position and a second position, the first position being a position in which the filter assembly 2 is located inside an air outlet of the cabinet air conditioner, and the second position being a position in which the filter assembly 2 is located outside the air outlet, and the air outlet is located on a side housing 100 of the cabinet air conditioner. In this technical solution, on the one hand, the filter assembly 2 can be changed between a first position and a second position, so that the same air outlet can adapt to different airflow directions, that is, it can not only not form adverse wind resistance to the outlet airflow when serving as an air outlet, but also can filter the inlet airflow when serving as an air inlet, which is particularly suitable for cabinet air conditioners with upper and lower air outlets; on the other hand, the filter surface of the filter 23 of the filter assembly 2 is arranged in a vertical direction, and can be in the air outlet when in the first position. Compared with the horizontally arranged filter assembly in the related art, the flow area of ​​the unfiltered airflow in the air outlet is significantly reduced, and the accumulation of debris in the airflow on the filter can be reduced, which can reduce the frequency of cleaning the filter assembly by users.

[0041] In some embodiments, the filter screen assembly 2 can be specifically slidably connected between the upper support member 11 and the lower support member 12, so that the change process between the first position and the second position is more reliable and convenient. Specifically, a slide 13 is constructed on the two side walls of the upper support member 11 and the lower support member 12 opposite to each other. The filter screen assembly 2 includes a frame 21 and a filter screen 23 covering and connected to the frame 21. The first end 211 of the frame 21 is located in the slide 13 of the upper support member 11, and the second end 212 of the frame 21 is located in the slide 13 of the lower support member 12. It can be understood that the first end 211 and the second end 212 are respectively located on opposite sides of the frame 21.

[0042] The structural shapes of the upper support member 11 and the lower support member 12 can be various, and can be specifically matched according to the shape of the air outlet. In some embodiments, the upper support member 11 is annular, and / or the lower support member 12 is annular. At this time, the shape of the frame 21 of the filter assembly 2 is also matched to be annular (for example, a full circle, but the corresponding filter 23 only covers part of it) or arc (for example, half a circle). Of course, the corresponding slide 13 is also annular or arc in the extension direction (that is, the sliding guide direction).

[0043] In order to make the sliding process of the filter assembly 2 smoother and reduce the wear of the upper support member 11 and the lower support member 12 on the frame 21, in some embodiments, a plurality of pulleys 22 are arranged at intervals along the sliding direction on the first end 211 and / or the second end 212. The pulley 22 can be connected to the corresponding rotating shaft horizontally, for example, in this way, a smooth sliding process can be achieved, and the best thing is that a plurality of pulley shafts 221 are arranged at intervals along the sliding direction on the first end 211 and / or the second end 212, and the plurality of pulley shafts 221 extend along the height direction, and each of the pulley shafts 221 is provided with a pulley 22, and matchingly, the slide 13 has a pulley groove 131 for accommodating the pulley 22, and the horizontal width of the pulley groove 131 is greater than the horizontal width of the opening of the slide 13 toward the side of the frame 21, so that the pulley 22 can not only guide the sliding of the filter assembly 2, but also effectively limit the displacement of the filter assembly 2 in the height direction, further ensuring the smoothness and reliability of the sliding. The free end of the pulley shaft 221 has a flange guide portion 222 and a gap 223 extending along its axial direction. The gap 223 can specifically be a cutout so that the pulley shaft 221 has the ability to deform along its radial direction, thereby making it easier to assemble the pulley 22 and the pulley shaft 221.

[0044] In order to improve the degree of automation of the filter mechanism, in some embodiments, the filter mechanism further includes a driving component, which can drive the filter assembly 2 to slide between the first position and the second position. Specifically, the driving component includes a rotary motor 31 (for example, a stepping motor) and a rotating shaft 32 connected to the power output shaft of the rotary motor 31, the rotating shaft 32 has a driving tooth portion 33, the mesh frame 21 has a rack 213, and the driving tooth portion 33 is meshed with the rack 213. In this technical solution, the position change of the filter assembly 2 is driven by the meshing design of the driving tooth portion 33 and the rack 213, and the control is more precise. Furthermore, the driving tooth portions 33 have at least two, and the two driving tooth portions 33 are spaced apart along the axial direction of the rotating shaft 32. At least two racks 213 are provided along the height direction of the grid 21, and at least two racks 213 respectively mesh with at least two driving tooth portions 33 in a one-to-one correspondence. By driving at least two meshing positions at different heights of the grid 21, the sliding can be made smoother.

[0045] In order to further reduce the frequency of cleaning the filter assembly 2, in some embodiments, the filter mechanism further includes a dust brush 4, which is disposed on the air inlet side of the filter assembly 2 so as to be able to clean the filter 23 during the sliding process of the filter assembly 2. The dust brush 4 may be, for example, a brush. In this technical solution, the dust brush 4 is fixedly located on the air inlet side of the filter assembly 2. When the filter assembly 2 is driven to slide by the driving component, the dust brush 4 can passively clean the filter 23 in contact with it without having to separately drive the dust brush 4 to rotate, thereby simplifying the structure and further reducing the cost.

[0046] In some embodiments, the filter mechanism further includes a dust box 5, which is located in the lower area of ​​the dust brush 4 and is used to receive the dirt (such as dust) brushed by the dust brush 4 to prevent the dirt brushed by the dust brush 4 from falling into the interior of the air conditioner. Furthermore, the wall of the dust box 5 has a through hole (not shown in the figure), and the through hole is connected to the second air duct 105 of the cabinet air conditioner. When the cabinet air conditioner receives a dust discharge instruction, the airflow in the second air duct 105 can guide the dirt in the dust box 5 into the second air duct 105, and discharge it to the outside through a connecting pipe (not shown in the figure) connected to the second air duct 105 (that is, the connecting pipe can connect the outdoor environment with the second air duct 105). It can be understood that the second air duct 105 is different from the first air duct 103 of the cabinet air conditioner. The flow area of ​​the second air duct 105 is generally much smaller than that of the first air duct 103. The first air duct 103 serves as the indoor return air and supply air of the cabinet air conditioner. A channel is provided in which corresponding airflow driving components 104 and heat exchangers 108 are provided, and the second air duct 105 can be opened and used when the dust box 5 of the air conditioner needs to discharge dust. At this time, the airflow with a larger air volume in the first air duct 103 is guided to the second air duct 105. Since the flow area of ​​the air duct becomes smaller, the airflow is accelerated. When the accelerated airflow flows through the through hole connecting the dust box 5 and the second air duct 105, a negative pressure will be generated in the storage space adjacent to the dust box 5 and the through hole, and then an induced effect will occur, so that the dust in the storage space will be induced into the airflow and finally discharged to the outdoors, without the user frequently cleaning the dust box 5. The through hole can preferably have a corresponding shut-off valve to prevent accidental discharge of dust under conditions where dust discharge is not required. In other embodiments, the dust box 5 can be pulled from the inside of the side-standing housing 100 to the outside of the side-standing housing 100, and at least a portion of the wall of the dust box 5 is exposed outside the side-standing housing 100 as an appearance surface, and a handle can be provided on the appearance surface so that the user can take the dust box 5 out of the air conditioner for thorough cleaning. Furthermore, the dust box 5 is designed to be locked by pressing it for the first time, and can be ejected from the inside of the air conditioner by pressing it again.

[0047] In some embodiments, the second air duct 105 can also be used as an input channel for fresh air. That is, when the air conditioner has a demand for introducing fresh air, the external fresh air can be introduced into the room through the airflow driving component 104 in the first air duct 103, without the need to separately match a corresponding fan for the introduction of fresh air, thereby simplifying the structure and reducing costs.

[0048] According to an embodiment of the present invention, a cabinet air conditioner is further provided, comprising a side-standing housing 100, wherein the side-standing housing 100 is provided with an air outlet, wherein the air outlet is provided with the above-mentioned filter mechanism. The air outlet comprises an upper air outlet 101 and a lower air outlet 102, wherein the upper air outlet 101 and the lower air outlet 102 are provided with the filter mechanism respectively, wherein the upper air outlet 101 and the lower air outlet 102 are connected through the first air duct 103, wherein the first air duct 103 is provided with an airflow driving component 104 (specifically, for example, a counter-rotating fan) and a heat exchanger 108. The upper air vent 101 and the lower air vent 102 in this technical solution can select the delivery path of the air flow according to the heating condition or the cooling condition of the air conditioner. For example, in the heating condition, the hot air flow can flow out from the lower air vent 102, and the small density rising characteristic of the hot air flow is used to achieve carpet-like temperature rise. In the cooling condition, the cold air flow can flow out from the upper air vent 101, and the large density falling characteristic of the cold air flow is used to achieve shower-like cooling, thereby improving the comfort of the air conditioner. As described above, when the filter mechanism includes a dust box 5 and the dust box 5 has a through hole, a second air duct 105 is also constructed in the side housing 100, and the second air duct 105 is connected to the outdoor environment through a connecting pipe, and the accommodating space of the dust box 5 is connected to the second air duct 105. Furthermore, the top opening of the second air duct 105 can be selectively connected to the top of the first air duct 103 through a first air door 106; and / or, the bottom opening of the second air duct 105 can be selectively connected to the bottom of the first air duct 103 through a second air door 107.

[0049] According to an embodiment of the present invention, there is also provided a control method for a cabinet air conditioner, which is used to control the above cabinet air conditioner, and comprises the following steps:

[0050] Get the control instructions of the air conditioner;

[0051] When the control instruction is heating, the filter assembly 2 in the filter mechanism corresponding to the upper air outlet 101 is controlled to be in the first position, and the filter assembly 2 in the filter mechanism corresponding to the lower air outlet 102 is controlled to be in the second position, that is, when the air conditioner is in the heating condition, the filter assembly 2 in the upper air outlet 101 is controlled to be inside the air outlet to filter the incoming air flow, and the filter assembly 2 in the lower air outlet 102 is controlled to be outside the air outlet to prevent obstruction to the outgoing air flow; contrary to the aforementioned heating, when the control instruction is cooling, the filter assembly 2 in the filter mechanism corresponding to the upper air outlet 101 is controlled to be in the second position, and the filter assembly 2 in the filter mechanism corresponding to the lower air outlet 102 is controlled to be in the first position.

[0052] When the control instruction is to remove dust from the filter, the filter assembly 2 in the filter mechanism is controlled to slide back and forth between the first position and the second position for multiple times. Specifically, it can be designed to remove dust from the filter assemblies 2 corresponding to the upper air outlet 101 and the lower air outlet 102 separately, or it can be designed to be performed simultaneously. The specific number of sliding times can be set according to actual needs, for example, three times or five times. When the control instruction is to shut down the air conditioner, the filter assemblies 2 in the filter mechanism corresponding to the upper air outlet 101 and the lower air outlet 102 are controlled to be in the first position to prevent external dirt from entering the air conditioner through the air outlet when the air conditioner is turned off.

[0053] In some embodiments, when a second air duct 105 is configured in the side-standing housing 100 and a top opening of the second air duct 105 is selectively connected to a top of the first air duct 103 through a first air door 106, and a bottom opening of the second air duct 105 is selectively connected to a bottom of the first air duct 103 through a second air door 107, when the control instruction is to discharge dust from a dust box, the control instruction further includes:

[0054] Determine the dust box 5 that needs to be discharged (specifically, determine whether it is the dust box 5 corresponding to the upper air outlet 101 or the lower air outlet 102. It can be understood that since the first air door 106 corresponds to the upper air outlet 101 and the second air door 107 corresponds to the lower air outlet 102, it can also be understood as determining whether it is the dust box 5 corresponding to the first air door 106 or the second air door 107);

[0055] When the determined dust box 5 corresponds to the first damper 106, the first damper 106 is controlled to open so that the top of the first air duct 103 is connected to the top opening of the second air duct 105, the second damper 107 is controlled to be closed so that the bottom of the first air duct 103 is cut off from the bottom opening of the second air duct 105, and the airflow driving component 104 is controlled to drive the indoor air flow toward the first damper 106; or, when the determined dust box 5 corresponds to the second damper 107, the second damper 107 is controlled to open so that the bottom of the first air duct 103 is connected to the bottom opening of the second air duct 105, the first damper 106 is controlled to be closed so that the top of the first air duct 103 is cut off from the top opening of the second air duct 105, and the airflow driving component 104 is controlled to drive the indoor air flow toward the second damper 107.

[0056] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above are only preferred embodiments of the present invention.
