Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a top-mounted filter cover, an indoor air conditioning unit, and an air conditioner. Background Technology

[0002] An air conditioner is a device that manually adjusts and controls indoor environmental parameters. It is widely used in homes, offices, commercial spaces, and industrial workshops to create a comfortable or specific indoor environment. The indoor unit typically consists of a casing with an air inlet at the top. A panel is located on the side of the casing facing the work area, and a filter is installed on the inside of the panel. After the air conditioner has been running for a period of time, the filter usually requires routine maintenance and cleaning.

[0003] In existing technology, cleaning requires opening the panel, removing the filter screen for cleaning, and then putting the filter screen back in its original position. Furthermore, the filter is usually installed on the filter screen, so cleaning the filter screen requires first removing the filter, then reinstalling the filter after cleaning the filter screen, and finally reinstalling both the filter and the filter screen in their original positions. However, this disassembly and assembly process is quite cumbersome.

[0004] Therefore, how to provide a top-mounted filter cover that simplifies the filter maintenance process is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model provides a top-mounted filter cover, an indoor air conditioning unit, and an air conditioner, to at least solve one of the above-mentioned problems in the prior art.

The side of the cover body corresponding to the panel has a filter mounting structure. The filter is detachably installed at the air inlet. When the filter needs to be cleaned, there is no need to open the panel; the filter can be directly removed from the air inlet. After the filter is cleaned, it can be directly reinstalled. The filter mounting structure is located on the side of the cover body corresponding to the panel. Therefore, compared with the prior art where the filter mounting structure is located on the filter, this utility model does not require interference from the filter when cleaning the filter, and does not require repeated disassembly and reassembly of the filter, making maintenance simple.

[0010] According to the present invention, a top-mounted filter cover is provided, wherein sliding grooves are provided on both sides of the air inlet along a first direction, and the sliding grooves allow the filter to slide into them, wherein the first direction is along the width direction of the air inlet.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] In the description of the embodiments of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] The following is combined Figures 1-4 This utility model provides a top-mounted filter cover for installing a filter on the top side of the cover body, which simplifies the filter installation and removal process compared to installing the filter on the side of the cover body closer to the panel.

[0040] This utility model provides a top-mounted filter cover, including a cover body 1 and a filter 4. An air inlet is provided on the top side of the cover body 1, and a panel 2 is provided on the side of the cover body 1 facing the indoor area. A filter mounting structure 3 is provided on the side of the cover body 1 corresponding to the panel 2, and the filter mounting structure 3 is used to install the filter. The filter in an air conditioner is a component used to filter impurities and pollutants in the air. Its core function is to improve the control quality of the air supply from the air conditioner, ensuring equipment operating efficiency and user health.

[0041] The filter screen 4 is detachably installed at the air inlet. When the filter screen 4 needs to be cleaned, there is no need to open the panel 2. The filter screen 4 can be directly removed from the air inlet and then reinstalled after cleaning. The filter mounting structure 3 is located on the side of the housing body 1 corresponding to the panel 2. Therefore, compared with the prior art where the filter mounting structure 3 is located on the filter screen 4, this utility model does not require interference from the filter when cleaning the filter screen 4, and does not require repeated disassembly and reassembly of the filter screen, thus simplifying the maintenance steps of the filter screen 4.

[0042] In one feasible embodiment of this utility model, sliding grooves are provided on both sides of the air inlet along a first direction, into which the filter screen slides. The first direction is along the width direction of the air inlet. The sliding grooves are arranged along the width direction, so that the installation path of the filter screen 4 is consistent with the natural movement direction of the human arm, eliminating the need for lifting. The filter screen 4 can be pulled out laterally from one side of the device without disassembling the entire panel, thus shortening maintenance time. In addition, the lateral sliding grooves ensure that the filter screen 4 is parallel and fits snugly against the air inlet plane, avoiding airflow deflection caused by the tilt of the filter screen 4 during traditional vertical installation.

[0043] In one feasible embodiment of this utility model, a plurality of slots 6 are provided on the housing body 1 near the air inlet panel 2, and a plurality of clips 5 are provided on the filter screen 4. When the filter screen 4 is installed, the clips 5 are engaged with the slots 6. Specifically, the clips 5 and the slots 6 form a spatial degree of freedom constraint, realizing a detachable connection. The clips 5 adopt an elastic cantilever structure, which can automatically correct angle deviations when sliding into the slots 6, and the engagement can be completed with one hand.

[0044] In one feasible embodiment of this utility model, the filter 4 is adapted to the shape of the air inlet. The shape adaptation makes the filter 4 and the air inlet form a continuous fluid boundary, avoiding airflow separation caused by shape differences. The shape adaptation ensures that the filter 4 completely covers the air inlet cross section, with no ineffective filtration area, maximizing the utilization of the filtration area and ensuring good airflow uniformity.

[0045] In one feasible embodiment of this utility model, the filter 4 includes two filter units, and the two filter units have the same structure. Disassembling the entire filter 4 into two filter units makes it easier to assemble and disassemble compared to installing only one filter unit at an air inlet. Furthermore, since the two filter units have the same structure, only one mold is needed to complete the manufacturing process, which reduces mold design, mold opening, and maintenance costs compared to filter units with different structures.

[0046] In one feasible embodiment of this utility model, the air inlet includes multiple first meshes 7, which are perforated. The filter 4 includes a filter body 41 and a snap-fit ​​frame 42. The filter body 41 includes multiple second meshes 411; the inner side of the second meshes 411 is provided with wire mesh; and the second meshes 411 are correspondingly arranged with the first meshes to form a uniform laminar flow when the airflow passes through. The snap-fit ​​frame 42 is located on the side of the filter body 41 near the panel 2, and a buckle 5 is provided on the snap-fit ​​frame 42. The snap-fit ​​frame 42 can achieve a good connection between the air inlet and the panel 2, and also provides an installation platform for the buckle 5. The wire mesh of the second meshes 411 can be selected with a suitable aperture according to actual needs.

[0047] In one feasible embodiment of this utility model, the filter body 41 has an arc-shaped structure, and the center of curvature of the arc-shaped structure is located on the side of the filter body 41 away from the air outlet direction. The arc-shaped structure causes the airflow to rotate naturally when it enters, and uses centrifugal force to throw large particulate pollutants to the outside of the filter screen 4. The setting of the center of curvature away from the air outlet direction makes the airflow form a laminar flow state with stronger adhesion on the surface of the filter material.

[0048] In one feasible embodiment of this utility model, the filter mounting structure 3 is integrally connected to the housing body 1. This integral connection eliminates the stress concentration problem at the joints of traditional split structures and allows the load to be transmitted substantially uniformly through continuous material. Specifically, the filter mounting structure 3 and the housing body 1 can also be molded in one piece using two-color injection molding or insert injection molding processes, eliminating traditional machining, surface treatment, and assembly procedures.

[0049] The first aspect of this utility model provides a top-mounted filter cover. The cover body 1 is first fixed to the corresponding wall surface at the usage location. When the air conditioner needs cleaning the filter 4 after a period of normal operation, it is not necessary to open the panel 2; simply pull the filter 4 out from the top air inlet. Furthermore, the filter mounting structure 3 is located on one side of the cover body 1 corresponding to the panel 2. Compared to the current technology where the filter mounting structure 3 is located on the filter, this utility model eliminates the need for interference from the filter when cleaning the filter 4, and avoids repeated disassembly and reassembly of the filter, thus demonstrating the simplicity of the filter 4 maintenance process.

[0050] The second aspect of this utility model is to provide an indoor air conditioning unit, including the top-mounted filter cover as described above.

[0051] The air conditioner indoor unit provided by this utility model has the above-mentioned advantages because it includes the top-mounted filter cover.

[0052] The third aspect of this utility model is to provide an air conditioner, including the top-mounted filter cover or the indoor unit as described above.

[0053] The air conditioner provided in this embodiment includes the top-mounted filter cover or indoor unit of any of the above embodiments. Since the air conditioner in this embodiment adopts all the technical solutions of any of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0054] The air conditioner provided in this embodiment can be a wall-mounted air conditioner.
