Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a filter assembly for refrigeration equipment. Background Art

[0002] There are many types of refrigeration equipment, among which wall-mounted air conditioners are the most common. As the air purification component of wall-mounted air conditioners, the ease of installation and removal of the filter directly impacts the user's maintenance experience. Traditional wall-mounted air conditioner filters are typically designed to snap into place via protrusions on the filter frame and slots on the housing. This method allows for tool-free installation and removal.

[0003] However, in actual operation, since the filter frame is mostly made of elastic plastic material, it is easy to deform due to uneven force during the pushing and pulling process, and there is no auxiliary docking structure during the docking with the slot on the casing, resulting in the clamping protrusion and the slot cannot be smoothly aligned, which requires the staff to repeatedly push and pull to adjust, increasing the complexity and inconvenience of the operation. Utility Model Content

[0004] In order to solve the problem that traditional wall-mounted air conditioner filters rely on the cooperation of snap-on protrusions and slots, which is prone to deformation due to uneven force and increases the difficulty of disassembly and assembly, the present application provides a refrigeration equipment filter assembly.

[0005] The present application provides a refrigeration equipment filter assembly adopting the following technical solution:

[0006] A refrigeration equipment filter assembly includes a hook shell, a filter housing is provided on the inner side of the hook shell, the filter housing includes a supporting shell with a plurality of filter placement slots, a filter unit is provided on the filter placement slot, and is used to remove large particle pollutants such as dust and pollen in the air. A plurality of guide members are provided on the outer side of the filter unit on the filter placement slot for guiding and limiting the filter unit.

[0007] Preferably, the filter unit comprises a filter frame with a layer of filter mesh laid on the surface, and the filter frame is provided with a toggle protrusion.

[0008] Preferably, a lower clamping groove is provided on one side of the filter placement groove.

[0009] Preferably, an upper clamping piece is provided on the side of the filter placement slot away from the lower clamping slot, and the upper clamping piece includes an arc-shaped guide plate provided on the filter placement slot, and the upper clamping slot is provided at the end of the arc-shaped guide plate.

[0010] Preferably, the guide member includes a pressure strip arranged on the filter placement slot, a stepped groove is arranged on the lower side of the pressure strip on the filter placement slot, and an arc-shaped guide strip is arranged on the side of the pressure strip close to the lower clamping slot.

[0011] In summary, this application has the following beneficial technical effects:

[0012] By cooperating with the filter housing and the filter unit, the arc-shaped guide strip is used to expand the docking range of the filter frame, while providing a downward extrusion to the edge of the filter frame so that it enters between the pressure strip and the stepped groove. The pressure strip and the stepped groove guide the edges of the filter frame on both sides, and then the arc-shaped guide plate expands the docking range between the upper clamping groove and the filter frame, preventing the filter frame from being deformed due to uneven force and unable to be inserted into the upper clamping groove. Compared with the existing technology, it has a simple structure and is easy to disassemble and assemble. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following is combined with Figure 1-3 This application is described in further detail.

[0018] The present application embodiment discloses a refrigeration equipment filter assembly. Figure 1-3 A refrigeration equipment filter assembly includes a hook shell 1, a guide fan 6 is installed inside the hook shell 1, a heat exchanger 7 is installed on the front of the guide fan 6, and an air inlet and an air outlet are provided on the hook shell 1, wherein a cover plate 4 is installed on the outside of the air inlet, and the cover plate 4 is used for convenient maintenance and cleaning. An air guide plate 5 is installed in the air outlet, and the wind direction can be adjusted by the air guide plate 5.

[0019] Reference Figure 2 , a filter housing 2 is installed in the air inlet, and the filter housing 2 includes a support shell 201 with two filter placement slots, a lower card slot 203 is opened on the lower side of the filter placement slot, and an upper clamp 204 is installed on the side of the filter placement slot away from the lower card slot 203. Figure 3The upper clamping member 204 includes an arc-shaped guide plate 2041 mounted on the filter placement slot, and an upper clamping slot 2042 is formed at the end of the arc-shaped guide plate 2041. The arc-shaped guide plate 2041 expands the docking range of the upper clamping slot 2042, reduces the difficulty of copying errors, and prevents the filter frame 301 from deforming due to uneven force when pushing, which may prevent it from being unable to be inserted into the upper clamping slot 2042.

[0020] Reference Figure 2 , the remaining two sides of the filter placement slot are provided with stepped slots 205, and the upper side of the stepped slots 205 is provided with guide members 202. Figure 3 The guide member 202 includes a pressure strip 2021 installed on the filter placement groove, and a stepped groove 205 is installed on the lower side of the pressure strip 2021 on the filter placement groove. An arc-shaped guide strip 2022 is installed on the side of the pressure strip 2021 close to the lower card slot 203. The length of the pressure strip 2021 is between one-third and two-thirds of the overall length of the stepped groove 205. For example, the length of the pressure strip 2021 is half of the overall length of the stepped groove 205, so that when the protrusion 302 is pushed up, the lower end of the filter frame 301 bends and separates from the lower card slot 203, so that the filter frame 301 can be quickly removed.

[0021] Reference Figure 3 A filter unit 3 is installed on the filter placement groove. The filter unit 3 includes a filter frame 301 with a layer of filter mesh laid on the surface. A sponge layer is added to the edge of the filter frame 301 to improve the sealing of the filtration. A toggle protrusion 302 is installed on the filter frame 301.

[0022] The implementation principle of a refrigeration equipment filter assembly in the embodiment of the present application is as follows:

[0023] When the filter needs to be replaced or cleaned, first open the cover 4 to expose the filter housing 2.

[0024] Manually push the push-pull projection 302 on the filter frame 301 to move it upward along the stepped groove 205 within the filter slot. During this movement, the filter frame 301 abuts against the upper retaining groove 2042, bending and separating the lower end of the filter frame 301 from the lower retaining groove 203. Pull the filter frame 301 in the opposite direction until it is completely free of the filter slot, allowing the filter to be easily removed for cleaning or replacement.

[0025] After cleaning or replacement, align the new filter frame 301 with the filter placement slot so that it is aligned with the arc guide bar 2022. Push the filter frame 301 upward by hand so that it bends along the arc guide bar 2022 and enters the stepped groove 205. Continue to push the filter frame 301 upward so that it slides along the stepped groove 205 to the correct position.

[0026] At this time, the upper end of the filter frame 301 will slide along the arc guide plate 2041 into the upper clamping groove 2041. Then put the upper end of the filter frame 301 into the lower clamping groove 203 to ensure that it is firmly fixed. Finally, close the cover 4 to complete the entire replacement process.

[0027] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
