Description

Technical Field

[0001] The utility model relates to the field of air conditioners, in particular to an anti-deformation structure of a hanging panel and an air conditioner. Background Art

[0002] The panel of a wall-mounted air conditioner is generally installed in conjunction with the middle frame. Since the panel occupies most of the exterior surface of the air conditioner indoor unit, there are high requirements for the fitting gap and fitting step between the panel and the middle frame. If the fitting gap and fitting step between the two are too large, the overall aesthetics of the air conditioner indoor unit will be greatly reduced.

[0003] In a traditional air conditioner indoor unit, the lower edge of the panel is located near the air outlet, and a row of buckles are provided on it for connecting with the middle frame. Therefore, the clearance between this position and the middle frame is well controlled; the upper edge of the panel is located near the air inlet, and its upper limit structure is relatively small. In the case of deformation of the panel itself, the deformation of the upper edge of the panel cannot be corrected, which is easy to produce assembly gaps and assembly steps, which have a great impact on the overall appearance of the air conditioner indoor unit and affect the user experience. Furthermore, the upper edge of the panel generally has a certain curvature, which often produces concave deformation or sagging deformation during injection molding, resulting in the above-mentioned fitting gaps and fitting steps when the panel is assembled. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a wall panel anti-deformation structure and an air conditioner, wherein the fitting gap and fitting step between the upper edge and the lower edge of the panel and the middle frame are small.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] A structure for preventing deformation of a hanging panel includes a panel and a middle frame, wherein the panel is rotatably mounted on the middle frame, a retaining rib is provided on the upper edge of the back of the panel, the retaining rib is continuously arranged along the upper edge of the panel, and an escape opening is provided on the lower edge of the retaining rib; the upper edge of the middle frame is a supporting surface, and a plurality of limit platforms protruding forward are arranged on the supporting surface, the limit platforms correspond to the escape openings one by one, and the upper surface of the limit platforms is a limiting surface, and when the panel is closed, the limit platforms are located in the corresponding escape openings, the upper edge of the panel is located above the limiting surface, and the retaining rib is located in front of the supporting surface; the lower edge of the panel is installed in cooperation with the middle frame through a first limiting structure. In this way, when the panel is closed, the limiting surface cooperates with the upper edge of the panel to prevent the upper edge of the panel from shrinking and deforming inward, and the supporting surface cooperates with the retaining rib so that the panel will not sink or collapse.

[0007] Preferably, the limit platforms are evenly arranged on the supporting surface, and the avoidance openings are evenly opened on the retaining ribs.

[0008] Preferably, the back of the panel is further provided with a plurality of supporting ribs, one end of which is fixedly connected to the panel, and the other end of which is fixedly connected to the retaining rib. The retaining rib is supported and strengthened by the supporting ribs to prevent the retaining ribs from being broken by stress.

[0009] Preferably, the shape of the limiting surface matches the shape of the upper edge of the panel.

[0010] Preferably, when the panel is closed, the gap between the limit surface and the upper edge of the panel is a, 1mm≥a≥0.3mm. If the gap is too small, the panel and the limit surface will interfere or get stuck during the movement of the panel, and if the gap is too large, the limit between the limit surface and the panel will fail.

[0011] Preferably, when the panel is closed, the gap between the retaining rib and the supporting surface is b, 1.5mm≥b≥0.5mm. If the gap is too small, the retaining rib and the supporting surface may interfere or get stuck during the movement of the panel, and if the gap is too large, the limit between the retaining rib and the supporting surface may fail.

[0012] Preferably, when the panel is closed, the gap between the front surface of the limit platform and the bottom surface of the avoidance opening is c, cb ≥ 0.3mm. In this way, when the panel collapses and deforms, the retaining ribs of the panel can first contact the supporting surface of the middle frame, thereby supporting the panel.

[0013] Preferably, a plurality of crisscross reinforcing ribs are arranged on the back of the panel, so as to enhance the strength of the panel.

[0014] Preferably, the first limiting structure includes a buckle arranged at the lower edge of the back side of the panel and a slot arranged at the lower edge of the middle frame, the buckle and the slot correspond one to one, and when the panel is closed, the buckle is locked in the slot.

[0015] An air conditioner comprises the above-mentioned anti-deformation structure of the hanging panel.

[0016] The utility model has the following beneficial effects due to the adoption of the above technical scheme: in the utility model, by setting a retaining rib on the upper edge of the panel and a limiting platform on the upper edge of the middle frame, when the panel is closed, the limiting surface cooperates with the upper edge of the panel to prevent the upper edge of the panel from shrinking and deforming inward, and the supporting surface cooperates with the retaining rib so that the panel will not sink and collapse, thereby solving the deformation problem of the upper edge of the panel, thereby improving the overall aesthetics of the air conditioner indoor unit and improving the user experience.

[0030] like Figures 1 to 5 The anti-deformation structure of a hanging panel shown in the figure includes a panel 1 and a middle frame 2. The panel 1 is rotatably mounted on the middle frame 2. A retaining rib 11 is provided on the upper edge of the back side of the panel 1. The retaining rib 11 is continuously arranged along the upper edge of the panel 1. The retaining rib 11 also strengthens the panel 1, thereby improving the deformation of the panel 1 so as to obtain a better assembly effect. An avoidance opening 111 is provided at the lower edge of the retaining rib 11; the upper edge of the middle frame 2 is a supporting surface 21, and a plurality of limit platforms 22 protruding forward are provided on the supporting surface 21, and the limit platforms 22 correspond to the avoidance opening 111 one by one. By setting the avoidance opening 11, it does not affect the assembly and opening and closing of the panel 1, and plays a limiting role.

When the panel 1 is closed, the limit platform 22 is located in the corresponding avoidance opening 111, the upper edge of the panel 1 is located above the limiting surface 221, and the retaining rib 11 is located in front of the supporting surface 21; the lower edge of the panel 1 and the middle frame 2 are installed in cooperation with each other through a first limiting structure.

[0031] In the utility model, by setting a retaining rib 11 on the upper edge of the panel 1 and a limiting platform 22 on the upper edge of the middle frame 2, when the panel 1 is closed, the limiting surface 221 of the limiting platform 22 cooperates with the upper edge of the panel 1 to prevent the upper edge of the panel 1 from shrinking and deforming inward, and the supporting surface 21 of the middle frame 2 cooperates with the retaining rib 11, so that the panel will not sink and collapse, thereby solving the deformation problem of the upper edge of the panel 1, thereby improving the overall aesthetics of the air conditioner indoor unit and improving the user experience; the lower edge of the panel 1 and the middle frame 2 are matched through the first limiting structure, so that the step and gap between the panel 1 and the middle frame 2 are small.

[0032] In the present invention, the limiting platform 22 is evenly arranged on the supporting surface 21 , and the avoidance opening 111 is evenly opened on the retaining rib 11 .
