Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air conditioner filter assembly and an air conditioner wall unit. Background Art

[0002] In household air conditioners, the air filter is usually installed at the air inlet to filter the air entering the air conditioner and prevent debris from entering the air conditioner. After the air conditioner has been used for a period of time, a large amount of dust and dirt will accumulate on the filter, and a large number of bacteria and viruses will be generated. These harmful substances circulate indoors with the air, polluting the air and endangering human health. In addition, the dirt on the dust filter will also reduce the cooling efficiency of the air conditioner, increase energy consumption, and shorten the service life of the air conditioner. Therefore, the dust filter must be cleaned after the air conditioner has been used for a period of time or when it is shut down for a season. Obviously, in addition to the dust filtering effect, the convenience of disassembly and assembly of the dust filter is one of the key indicators to measure the overall performance of the component.

[0003] In the prior art, the air conditioner is relatively long, and the filter installed inside is generally a two-piece type. Installation and removal need to be performed separately, and multiple operations are performed during the installation and removal process as well as the cleaning process, which is time-consuming and labor-intensive.

[0004] It can be seen from this that it is necessary to invent an air conditioning filter assembly that can complete the installation, disassembly and cleaning of the filter in one go, with a simple structure and convenient operation. Summary of the invention

[0005] The invention has the advantages of completing the installation, disassembly and cleaning of the filter screen at one time, which is simple and quick.

[0006] In order to solve the above problems, the present invention provides an air conditioning filter assembly.

[0007] An air conditioning filter assembly comprises a middle frame and a filter, wherein the filter comprises a left filter and a right filter, wherein the left filter and the right filter are mounted on the middle frame, wherein the left filter and the right filter are integrally formed, and a filter fixing piece is disposed in the middle of the middle frame, wherein the filter fixing piece can be opened to place the filter, and the filter fixing piece can be closed to press the filter onto the middle frame.

[0008] The filter is changed from the original two-piece structure to an integrated structure, that is, it is changed to a one-piece structure. The installation and removal of the filter can be completed in one operation, saving time and effort. The center position of the middle frame relative to the left and right sides is the middle of the middle frame. The filter fixing part presses the filter in the middle of the middle frame to prevent the filter from warping and deformation.

[0009] Furthermore, one end of the filter fixing piece is rotatably connected to the middle frame, and the other end is detachably connected to the middle frame to open and close the filter fixing piece.

[0010] The filter screen fixing part can be rotated and lifted when the filter screen fixing part is opened, and rotated and dropped when the filter screen fixing part is closed.

[0011] Furthermore, the middle frame includes a middle frame end face and an air inlet grille. A slide groove is provided on the air inlet grille. The filter is inserted into the slide groove to block the air inlet grille and cover the middle frame end face.

[0012] The air inlet grille is arranged on the middle frame and can be formed in one step for easy mass production, and the integrated structure has good strength. The filter is inserted into or pulled out of the middle frame through a slide groove, and the filter can be installed and removed without disassembling the middle frame, which facilitates the installation and removal of the filter.

[0013] Furthermore, the filter fixing member is arranged in the middle of the end surface of the middle frame, a filter fixing portion is arranged in the middle of the filter, and the filter fixing member is pressed on the filter fixing portion.

[0014] The filter is an integrated structure with a long length, and is prone to warping in the middle. The connection between the left filter and the right filter is the middle of the filter, and the filter fixing part is arranged in the middle of the end face of the middle frame. After the filter is installed, the filter fixing part corresponds to the filter fixing part, and the filter fixing part presses the filter through the filter fixing part to prevent the filter from warping and deformation.

[0015] Furthermore, the filter fixing piece is provided with a mounting portion, the air inlet grille is provided with a fixing seat, and the mounting portion is rotatably arranged on the fixing seat.

[0016] The filter fixing part can be positioned at the air inlet grille, or can be hinged, or can be other forms of rotational connection, and the rotation angle is determined according to the space where the air conditioner is installed.

[0017] Furthermore, the end surface of the middle frame is provided with a support bar, and the slide groove extends and is connected to the support bar.

[0018] The support bar, as part of the slide, guides the filter when it is inserted into the middle frame.

[0019] Furthermore, the slide groove includes a slide groove extension arm, and the edge of the slide groove extension arm abuts against the filter fixing piece.

[0020] The filter fixing part is suspended near the air inlet grille, and the slide slot extension arm prevents the filter fixing part from deforming at the suspended part and plays a certain guiding role when installing the filter.

[0021] Furthermore, a torsion spring is provided at the connection between the fixing seat and the mounting portion.

[0022] When the filter fixing part is lifted, the torsion spring is stretched to generate elastic force. After the filter is installed, the filter fixing part is loosened. Under the elastic force of the torsion spring itself, the filter fixing part is reset to press the filter.

[0023] Furthermore, the filter fixing piece is provided with a clamping portion, the end surface of the middle frame is provided with a clamping slot, and the clamping portion and the clamping slot are detachably connected.

[0024] The clamping part and the clamping slot play the role of a switch. When the clamping part and the clamping slot are disassembled, the filter screen is installed, the clamping part is connected to the clamping slot, and the filter screen fixing part presses the filter screen.

[0025] Compared with the prior art, the air conditioning filter assembly described in the present invention has the following advantages:

[0026] (1) The air conditioner filter assembly of the present invention has a filter that is an integrated structure of two pieces. The filter can be removed and inserted once instead of twice, and is easy to disassemble and install.

[0027] (2) The air conditioning filter assembly described in the present invention is provided with a filter fixing member to press and fix the filter, thereby preventing the filter from being too long and not being installed tightly, thereby affecting the installation of the panel, etc.

[0028] An air conditioner wall mounted unit includes the air conditioner filter assembly described above. The air conditioner wall mounted unit has the same beneficial effects as described above. BRIEF DESCRIPTION OF THE DRAWINGS

The middle frame end face 10 is arranged at the front of the middle frame 1, and the air inlet grille 12 is arranged at the upper part of the middle frame 1. The air inlet grille 12 and the middle frame end face 10 are arranged at an angle of 80° to 100°. The air inlet grille 12 and the middle frame end face 10 are enclosed to form a chamber for placing components such as an air-conditioning fan. The side of the middle frame end face 10 away from the chamber is the outer side of the middle frame end face 10, and the side of the air inlet grille 12 close to the chamber is the inner side of the air inlet grille 12. The filter 2 is bent to cover the outer side of the middle frame end face 10 and the inner side of the air inlet grille 12. The filter fixing member 11 is arranged in the middle part of the middle frame 1 along the width direction of the middle frame 1, that is, at a position centered relative to the left and right sides of the middle frame 1, one end is hinged to the inner side of the air inlet grille 12, and the other end is clamped to the outer side of the middle frame end face 10.
