[0037] As the main filter component in the air conditioner structure, the filter element can filter out most of the floating dust in the air. Some filter elements can further purify various harmful substances in the air, thereby improving the overall quality of the air discharged from the air conditioner. As the main filtering structure, it needs to be cleaned regularly during use to ensure its filtering quality of the air. The traditional method of cleaning the filter element is to disassemble it manually, clean it, and then reinstall it. This traditional cleaning method is not only inconvenient but also likely to damage the installation structure during the disassembly and installation process. The present utility model provides a filter element cleaning structure and an air conditioner to solve the problems of inconvenience and high manual operation difficulty in the traditional method of cleaning the air conditioner filter element.

[0038] The present utility model proposes a filter element cleaning structure and an air conditioner to solve the above problems.

[0039] Please refer to Figures 1 to 3, As a filter element in the air conditioner structure, it can filter out most of the floating dust and floating objects in the air, thus ensuring the quality of the cold / hot air discharged from the air conditioner. Therefore, generally after the filter element is used for a period of time, in order to ensure the intake efficiency and the quality of the intake air of the air conditioner structure, it is necessary to clean or replace the filter element. During this process, the cleaning of the air conditioner filter element is mostly to manually remove the filter element structure from the inside of the air conditioner and then clean or replace it. In the traditional cleaning method, the manual labor intensity is high, and disassembly and installation are required. Especially during the disassembly and installation process, it is easy to damage the internal structure of the air conditioner. In this embodiment, it mainly aims at the vertical air conditioner structure, in which a corresponding cleaning component is provided to automatically clean the filter element 6. After the filter element 6 is specifically installed, its two ends are respectively fixedly installed on the fixed frame 2 and the movable frame 5. External air enters from the intake cavity 11 and enters the diversion cavity 12 through the diversion holes 18 on the fixed frame 2 and the movable frame 5. The external air passes through the filter element 6 for filtration, and the filtered substances in the air adhere to the outer wall of the filter element 6. When cleaning the filter element 6, first, the blow component is arranged corresponding to the upper end of the diversion hole 18, and air is blown into the filter element 6 through the blow component, so that the filtered substances attached to the surface of the filter element 6 are separated from the filter element 6. At the same time, during the blowing process, the blowing part will drive the rotary cleaning part 4 to rotate on the fixed frame 2 and the movable frame 5. When one end of the rotary cleaning part 4 contacts the outer wall of the filter element 6, the filtered substances on the outer wall of the filter element 6 will be further scraped off, thus effectively ensuring the filtering performance of the entire filter element 6.

[0040] Among them, the fixed frame 2 is set as two parts in the vertical direction. Specifically, the first frame part 21 is fixedly installed on the inner wall of the housing 1, and the second frame part 22 is connected to the first frame part 21 through a connection structure. One end of the second frame part 22 is used to fix the upper end of the filter element 6, and a rotary installation part is defined between the first frame part 21 and the second frame part 22. One end of the rotary cleaning part 4 is rotatably installed on the rotary installation part. The connection structure includes a connecting rod 23. The diversion hole 18 is jointly defined on the inner sides of the first frame part 21 and the second frame part 22. A first connecting frame 211 and a second connecting frame 221 are respectively provided at the central positions of the first frame part 21 and the second frame part 22. The first connecting frame 211 and the second connecting frame 221 are fixed into a whole through the connecting rod 23.

[0041] The rotating cleaning member 4 is driven by the air outlet of the blowing member. Specifically, the inner fan blades are rotatably installed on the rotating installation part between the first frame part 21 and the second frame part 22. A plurality of wind-receiving blades are arranged inside the inner fan blade ring 411. During the air outlet process of the blowing member, after the plurality of wind-receiving blades are affected by the wind, the whole will rotate between the first frame part 21 and the second frame part 22. During the rotation of the inner fan blade ring 411, the brush plate 42 on the mounting plate 412 will slide in contact with the outer wall of the filter element 6, so as to brush off the filter substances on the outer wall of the filter element 6. By setting the above double-cleaning structure, the plurality of brush plates 42 can remove some of the filter substances on the outside of the filter element 6 that have not been blown off by the blowing member, so as to achieve a better cleaning effect.

[0042] Among them, the blowing member mainly includes a blowing device and a driving device. The blowing device is arranged in the diversion cavity 12, and the blowing device is slidably installed on the guiding frame 321 of the driving device in the vertical direction. When the driving member works, it will drive the blowing device to move in the vertical direction to realize the connection or separation between the blowing device and the diversion hole 18. When the blowing device is separated from the diversion hole 18, the gas in the intake cavity 11 can be guided to the diversion cavity 12 after being filtered by the filter element 6. When the blowing device is connected to the upper end of the diversion hole 18, the blowing device can effectively prevent gas leakage during operation, so as to achieve a better cleaning effect on the filter element 6. During the specific cleaning process of the filter element 6, the blowing device realizes a non-contact gas cleaning method, and the rotating cleaning member 4 realizes a contact cleaning method. The combination of the two methods can effectively remove the filter substances on the filter element 6 and achieve a better self-cleaning effect. In the actual use process, automatic control can be achieved by setting a program. For example, during the intake air filtration process, the air flow rate is monitored. When the air flow rate is less than the preset value, the corresponding cleaning member is controlled by the corresponding program to clean the filter element 6, so as to achieve automatic control. Compared with the traditional manual cleaning method, it can effectively reduce the manual labor intensity on the premise of ensuring the cleaning effect, and can avoid damage to the installation structure caused by improper operation during the disassembly and installation of the filter element 6.

[0043] Specifically, the injection device includes an injection head 311 and a gas supply component (not shown in the figure). A ring-shaped portion is provided on the circumferential side wall of the injection head 311. The ring-shaped portion is slidably mounted on a plurality of guide shafts 325 on the guide frame 321. The driving device drives the injection head 311 to cooperate with the end of the diversion hole 18. At this time, the gas supply component supplies gas to the injection head 311, so as to blow off the filter substances attached to the filter element 6. The gas supply component can be set as an air pump, which can continuously or intermittently output gas with a certain pressure into the filter element 6, so as to adjust the effect of injection dust removal.

[0044] It can be conceived that the driving device is a linear driving structure. In this embodiment, the driving device is set as a motor 323 and a lead screw 324 mechanism. Among them, the motor 323 is fixedly installed on the first frame portion 21. One end of the lead screw 324 is rotatably installed on the guide frame 321, and the other end thereof is connected to the output end of the motor 323. The ring-shaped portion is threadedly connected to the lead screw 324. When the motor 323 works, it can drive the lead screw 324 to rotate, so as to realize the movement of the injection head 311 on the guide frame 321.

[0045] In another embodiment, the movable frame 5 is used to fix the lower end portion of the filter element 6. During the actual operation process, the movable frame 5 has a movement stroke in the vertical direction, and can realize the contact fixation and separation effect with the end portion of the filter element 6. In the specific installation process, first press down the ring-shaped movable portion 52 to make the contact fixation portion 51 move downward, so as to define a sufficient vertical installation space between the contact fixation portion 51 and the second frame portion 22. Then, first fix the upper end portion of the filter element 6 on one end of the second frame portion 22, and then release the ring-shaped movable portion 52. Under the action of the force of a plurality of springs 54, the contact fixation portion 51 is buckled on the lower end portion of the filter element 6 for fixation, so as to fix the filter element 6 in the air inlet cavity 11 through the contact fixation portion 51 and the second frame portion 22. During this process, the ring-shaped movable portion 52 slides on a plurality of mounting shafts 161, and the blown-off and scraped filter substances fall into the inner cavity of the lower end portion of the housing 1 through the gaps between a plurality of first connecting plates 53.

[0046] Among them, in order to facilitate the collection of the filter substances falling on the filter element 6, an ash collecting hopper 16 is provided in the lower part of the air inlet chamber 11. The ash collecting hopper 16 is arranged corresponding to the lower part of the movable frame 5, and its cross section gradually decreases from top to bottom. An activity drawer 17 is slidably connected to the outlet end of the ash collecting hopper 16. The filter substances falling from the filter element 6 are centrally collected in the activity drawer 17. During subsequent cleaning, the activity drawer 17 can be taken out from the inside of the housing 1, so as to clean the collected filter substances. In addition, a plurality of the mounting shafts 161 are all mounted on the mounting surface at the upper end of the ash collecting hopper 16.

[0047] At a position corresponding to the air inlet chamber 11 on the housing 1, an air inlet grille 13 is provided. The air inlet grille 13 is provided with an actively adjustable grille structure. When admitting air, the air inlet grille 13 is opened, and when cleaning the filter element 6, the air inlet grille 13 is closed. The adjustable grille structure is a known structure and will not be elaborated here. In addition, a fan structure 14 is provided in the diversion chamber 12. When the fan structure 14 works, it can introduce external air into the air inlet chamber 11, and then after passing through the filter element 6, it is diverted into the diversion chamber 12.

[0048] In another embodiment, during the operation of the blowing member, the air pressure in the air inlet chamber 11 will increase. In this embodiment, a plurality of filter members 15 are provided on the housing 1 at a position corresponding to the air inlet chamber 11. The gas in the air inlet chamber 11 can be discharged to the outside of the housing 1 after being filtered through the filter.

[0049] The present utility model also discloses an air conditioner, which includes a filter element cleaning structure 100. The filter element cleaning structure 100 is as described in the above embodiment. Therefore, the air conditioner has the beneficial effects shown by the filter element cleaning structure 100, which will not be elaborated one by one here.
