Description

Technical Field

[0001] The utility model relates to the technical field of filtration, in particular to a filter screen component and an air duct machine. Background Art

[0002] Traditional duct air conditioners only have one type of filter, which cannot meet the usage requirements in various scenarios. In different application scenarios, the requirements for filters are different. For example, under some conditions (such as high air quality or users need to quickly adjust the indoor temperature), high air volume and rapid cooling or heating are required. At this time, if a filter with high filtration accuracy is installed in the duct air conditioner, it will cause large filter wind resistance and cannot meet the needs of rapid cooling and heating. Under some conditions (such as poor air quality or the indoor temperature is not much different from the user's target temperature), rapid cooling or heating is not required, but a higher purification level is required to purify the air. At this time, if the duct air conditioner does not have a filter installed or the filter has insufficient filtration accuracy, it cannot meet the air purification requirements, seriously affecting the working reliability of the duct air conditioner.

[0028] Traditional duct air conditioners have only one type of filter, which cannot meet the needs of use in various scenarios. In different application scenarios, the requirements for filters are different. For example, under some conditions (such as high air quality or users need to quickly adjust the indoor temperature), high air volume and rapid cooling or heating are required. At this time, if a filter with high filtration accuracy is installed in the duct air conditioner, it will cause large wind resistance of the filter, and the needs of rapid cooling and heating cannot be met. Under some conditions (such as poor air quality or the indoor temperature is not much different from the user's target temperature), rapid cooling or heating is not required, but a higher purification level is required to purify the air. At this time, if no filter is installed in the duct air conditioner or the filtration accuracy of the filter is insufficient, the air purification requirements cannot be met, which seriously affects the working reliability of the duct air conditioner. To this end, the present application provides a method such as Figures 1 to 3 The filter assembly shown includes: two storage structures 1, the two storage structures 1 being spaced apart; a filter 2, the filter 2 being disposed between the two storage structures 1, with both ends of the filter 2 respectively connected to the two storage structures 1, and the storage structures 1 being capable of driving the filter 2 to move and to partially store the filter 2; the filter 2 having at least two filter sections 21, all of which have different filtration accuracies. By connecting the two ends of the filter 2 with the two storage structures 1, the storage structures 1 are capable of driving the filter 2 to store and simultaneously drive the filter 2 to move, thereby switching between different filter sections 21 for filtration, allowing the filter assembly to simultaneously achieve different filtration accuracies, thereby enabling the filter assembly to adapt to different filtration accuracy requirements, thereby improving the scope of application and operational reliability of the filter assembly and the duct air conditioner.

[0029] When in use, the two storage structures 1 are respectively arranged on both sides of the air outlet, so that part of the filter 2 can cover the air outlet, ensuring reliable filtration of the air at the air outlet. When different filtration accuracies are required, the storage structure 1 is controlled to store the filter 2, so that the filter 2 moves, switching different filter parts 21 to move to the air outlet, and achieving switching of different filtration accuracies. For example, there are two filter parts 21. At a first filtration accuracy, the storage structure 1 on the left is only connected to the end of the first filter part 21. At this time, the first filter part 21 is located at the air outlet, and the second filter part 21 is stored in the storage structure 1 on the right. At a second filtration accuracy, the storage structure 1 on the left begins to store the filter 2, and at the same time, the storage structure 1 on the right begins to release the filter 2, so that the first filter part 21 is stored by the storage structure 1 on the left, and the second filter part 21 is released by the storage structure 1 on the right and moves to the air outlet, thereby achieving switching of the first filter part 21 and the second filter part 21 for filtering the air outlet, and finally achieving switching of different filtration accuracies.

[0030] In one embodiment, the storage structure 1 includes a drum 11, to which the end of the filter screen 2 is connected, and the drum 11 is capable of rotating to wind the filter screen 2 around the drum 11. The filter screen 2 is wound around the drum 11 to store the filter screen 2, and when the drum 11 rotates in the opposite direction, the filter screen 2 can be released.

[0031] The storage structure 1 further includes a driving member 12, which is connected to the reel 11 and can drive the reel 11 to rotate. The driving member 12 drives the reel 11 to rotate, thereby achieving the technical effect of automatically switching the filtration accuracy of the filter assembly. Specifically, the driving member 12 can drive the reel 11 to rotate forward and reverse, thereby achieving controllable storage and release of the filter 2.

[0032] Among them, the driving parts 12 of the two storage structures 1 drive the reels 11 to rotate in the same direction, that is, the two reels 11 rotate forward or reverse synchronously, so as to ensure that one reel 11 releases the filter 2 while the other reel 11 can reliably store the filter 2, ensuring that the filter 2 is always in a flat state to reliably filter the air outlet, avoiding problems such as bending and wrinkling of the filter 2, and improving the reliability of the filter assembly.

[0033] The filter assembly further includes a cleaning structure 3, which is disposed between the two storage structures 1 and is capable of cleaning the filter 2. The cleaning mechanism cleans the filter 2 to ensure its cleanliness, thereby improving the air flow efficiency of the filter 2 and extending the service life of the filter 2.

[0034] In one embodiment, the cleaning structure 3 includes a brush 31, which is attached to the filter 2 and cleans the filter 2 when the filter 2 moves. The storage structure 1 drives the filter 2 to move relative to the brush 31, and the brush 31 can then scrub the filter 2 to complete the cleaning of the filter 2.

[0035] Along the moving direction of the filter screen 2, a plurality of brushes 31 can be provided, so that the filter screen 2 can be cleaned multiple times, thereby improving the cleanliness and air flow efficiency of the filter screen 2.

[0036] Furthermore, the number of the brushes 31 is at least two, at least one of which is located on the windward side of the filter 2, and at least one of which is located on the leeward side of the filter 2. The brushes 31 are used to clean both sides of the filter 2 simultaneously. In particular, by brushing on the leeward side, dust and impurities that are about to pass through the filter 2 can be brushed away, thereby further improving the cleanliness of the filter 2.

[0037] The filter assembly further includes a dust box 4, which is located below the cleaning structure 3. The dust box 4 collects dust and impurities cleaned from the filter 2 by the cleaning structure 3, thereby preventing dust and impurities from re-entering the air and causing secondary pollution, and also facilitates the user to clean the filter assembly.

[0038] A duct air conditioner includes the above-mentioned filter assembly.

[0039] The duct air conditioner includes a shell, an air outlet is provided on the shell, the filter assembly is provided at the air outlet, and any one of the filter parts 21 can cover the air outlet, that is, the air outlet can be filtered by a single filter part 21 at this time, so that the entire air outlet is at the same filtering accuracy, ensuring that the air volume of the air outlet is uniform, and improving the working efficiency of the duct air conditioner.

[0040] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
