Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to a filter component and an air conditioner. Background Art

[0002] Air conditioners are widely used as daily household appliances. After a period of use, air conditioners need to be cleaned, such as cleaning the air inlet grille, cleaning the air duct and the components in the air duct (fan, sweeping blades). In the prior art, a corresponding water or steam nozzle device has been set in the air duct of the air conditioner to automatically clean the air duct and the components in the air duct. In view of the shortcomings of cleaning the air inlet filter of the air conditioner, the inventor has made necessary research in the early stage and proposed a corresponding technical solution. The filter assembly with switchable position of the filter is adopted to realize the dual function requirements of cleaning the filter and filtering the filter. When the filter is in the cleaning position, in order to prevent the cleaning fluid from being sprayed out of the air conditioner at the corresponding position, the corresponding sealing plate is assembled in the corresponding area of the filter cleaning position in the prior art. This assembled sealing plate structure inevitably needs to be docked and sealed with the hollow plate of the filter assembly on the outside of the air conditioner. On the one hand, this method makes the assembly process relatively complicated. On the other hand, there is a phenomenon that dirt is hidden at the joint and the cleaning fluid seeps out of the outside of the air conditioner. Based on this deficiency in the prior art, the present invention is proposed. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to provide a filter assembly and an air conditioner, which can simplify the installation process of the filter assembly and the air conditioner, and completely eliminate the phenomenon of dirt and grime being trapped and cleaning fluid leaking out of the outside of the air conditioner due to the joint formed by the assembly and connection of the sealing plate and the first perforated plate in the prior art.

[0004] In order to solve the above-mentioned problem, the present invention provides a filter assembly, comprising: an outer perforated plate, an inner perforated plate, and a filter screen that are relatively arranged, the filter screen is located in a accommodating space formed by the outer perforated plate and the inner perforated plate, the filter screen has a first position for filtering the air intake of the air conditioner and a second position for being cleaned by a cleaning fluid, the outer perforated plate has an outer airflow inflow portion corresponding to the first position and a sealing portion corresponding to the second position.

[0025] With reference to Figures 1 to 9As shown, the present invention provides a filtering component, comprising: an outer perforated plate 1, an inner perforated plate 2, and a filter screen 3 which are oppositely arranged. The filter screen 3 is located in the accommodation space formed by clamping the outer perforated plate 1 and the inner perforated plate 2. The filter screen 3 has a first position for filtering the incoming air of the air conditioner and a second position where it can be cleaned by a cleaning fluid. The outer perforated plate 1 has an outer air flow inlet portion 11 corresponding to the first position and a sealing portion 12 corresponding to the second position. In this technical solution, by integrally forming the sealing portion 12 and the outer air flow inlet portion 11 as the outer perforated plate 1, there is no need to separately assemble a corresponding sealing plate component as in the prior art. Thus, there is no need to position the relative positional relationship between the sealing plate and the perforated plate, and no seam (gap) as in the prior art is formed between the two. On the one hand, this can simplify the installation process of the filtering component and the air conditioner and improve the assembly efficiency of the component. On the other hand, it can completely prevent the phenomenon of dirt accumulation and leakage of the cleaning fluid outside the air conditioner caused by the assembly and connection of the sealing plate and the first perforated plate in the prior art. The outer perforated plate 1 and the inner perforated plate 2 are preferably connected in a detachable manner, for example, by means of snap fasteners to achieve the relative assembly of the two, thereby facilitating the assembly of the filter screen 3. Corresponding mounting structures 14 are provided on the outer perforated plate 1 and the inner perforated plate 2, for example Figure 1 corresponding mounting pieces or mounting holes are provided at the outer peripheral edge of the sealing portion 12 as shown in, so that the filtering component can be connected to the bottom case 200 of the air conditioner by means of bolting.

[0026] The outer perforated plate 1 can be formed by injection molding in an integrally formed manner, for example. However, for this formed outer perforated plate 1, the assembly method has extremely high requirements for installation accuracy, and at the same time, the accuracy requirements for the forming process are also extremely high. To overcome this deficiency, preferably, there is a deformation part 13 between the outer air inflow part 11 and the sealing part 12. The deformation part 13 can ensure that a preset angle is formed between the outer air inflow part 11 and the sealing part 12. The purpose of setting the deformation part 13 is to enable the bending angle between the outer air inflow part 11 and the sealing part 12 to be adjusted according to the selection during the assembly process, so as to facilitate the assembly process. This method is especially applicable when the inner perforated plate 2 has an inner air inflow part 21 corresponding to the first position and a cleaning fluid circulation part 22 corresponding to the second position, and a preset angle is formed between the inner air inflow part 21 and the cleaning fluid circulation part 22. At this time, the matching between the inner perforated plate 2 and the outer perforated plate 1 will be more easily achieved due to the setting of the deformation part 13. It can be understood that at the second position, the switching movement of the filter net 3 between the first position and the second position is completely restricted by the clamping of the outer perforated plate 1 and the inner perforated plate 2, so that the switching movement of the filter net 3 is smoother. And the well-matched outer perforated plate 1 and inner perforated plate 2 can effectively prevent the filter net 3 from getting stuck during movement and ensure the smoothness of its movement. This design method using the deformation part 13 can also make it possible to integrally injection mold the inner perforated plate 2, thereby further reducing the processing difficulty of the components. The specific setting of the preset angle is based on the specific structural form of the air conditioner and the consideration of the aesthetic appearance, for example Figure 1 as shown, the preset angle is approximately 90°.

[0027] In order to be able to automatically switch the position of the filter screen 3, preferably, the filter assembly further includes a filter screen position switching drive mechanism 4 for driving the filter screen 3 to switch between the first position and the second position. Specifically, the filter screen position switching drive mechanism 4 includes a rotating shaft 41 and a rotary drive component drivingly connected to the rotating shaft 41, and the rotating shaft 41 is connected to the filter screen 3 by gear meshing. For example, a first gear is assembled or integrally formed on the rotating shaft 41, and a corresponding first rack is constructed on the side of the filter screen 3 facing the rotating shaft 41. The teeth on the first rack and the teeth on the first gear mesh with each other to form a gear drive, and the first gear is assembled on the output shaft of the rotary drive component. The rotary drive component includes a motor 42, the motor 42 is installed on the inner perforated plate 2, and an installation structure for the rotating shaft 41 is formed at a position corresponding to the deformation part 13 on the inner perforated plate 2. In this way, the filter assembly can form a relatively independent assembly, and after being assembled, it can be assembled with other components of the air conditioner, such as the bottom case 200, further reducing the assembly difficulty.

[0028] According to an embodiment of the present invention, an air conditioner is further provided, which includes a filtering component 100, and the filtering component 100 is the above-mentioned filtering component. Specifically, the filtering component 100 is disposed on the air inlet side of a blower 400 of the air conditioner, and a heat exchanger 300 is disposed between the blower 400 and the filtering component 100. That is to say, the filtering component 100 is on the outer side of the air conditioner, and it is assembled with a bottom case 200 into an integral body through a mounting structure 14. As a specific application mode, preferably, the air conditioner is a top air inlet air conditioner, and further includes a cleaning spray head 51 for spraying a cleaning fluid onto a filter net 3 at a second position to clean the filter net 3. It can be understood that the cleaning spray head 51 will be selectively connected to a pressure fluid source. As a prior art, it is not particularly limited in the present invention. At this time, in order to prevent the cleaning fluid from spraying out of the air conditioner from an upper air inlet as much as possible, preferably, a downward inclination angle A is formed between the jet axis of the cleaning spray head 51 and the horizontal direction, so as to limit the path of the cleaning fluid sprayed by the cleaning spray head 51 in a physical structure. Preferably, 90° > A ≥ 1°, so as to clean the filter net 3 in the largest range in the vertical direction; further, the spray angle of the cleaning spray head 51 is B, the horizontal width of the filter net 3 is L, and the horizontal distance between the cleaning spray head 51 and the filter net 3 is D, and L ≤ Dtan(B / 2), which can ensure that the cleaning spray head 51 cleans the filter net 3 in the largest range in the horizontal direction, so that the filter net 3 is completely covered by the spraying range of the cleaning spray head 51 in the horizontal width; preferably, after the filtering component is assembled, the minimum horizontal distance between the hole edge of the outer perforated plate 1 and the sealing portion 12 is d, and 80mm ≥ d ≥ 10mm. Limiting the range of d here can prevent the cleaning fluid from flowing out of the air conditioner through the perforations during the cleaning process due to it being too small, and on the other hand, can prevent an adverse impact on the air intake volume of the air conditioner due to it being too large.

[0029] It is easy for those skilled in the art to understand that, on the premise of no conflict, the above-mentioned advantageous ways can be freely combined and superimposed.

[0030] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above is only the preferred implementation mode of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and variations can be made without departing from the technical principle of the present invention, and these improvements and variations should also be regarded as the protection scope of the present invention.
