Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0027] First, the existing air inlet grille of the air conditioner is described.

[0028] The outlet position of the drain pipe on the existing air inlet grille of the air conditioner is generally set at a distance of 120-160mm from the ground. In actual user scenarios, the wall outlet may be greater than 160mm from the ground. At this time, the outlet position of the air inlet grille drain pipe is lower than the wall outlet, which will cause the air conditioner to have poor drainage and water accumulation in the drain pipe. In order to solve the above problems, some existing air conditioners choose to raise the position of the drain pipe outlet on the air inlet grille to 260-270mm from the ground. However, such an adjustment will cause the maintenance plate on the air inlet grille to move up, thereby increasing the distance between the bottom edge of the maintenance plate and the bottom edge of the air inlet grille and lengthening the lever arm. Through simulation model analysis, it is found that there is a "pressure rod instability" phenomenon. Therefore, how to ensure the structural strength of the air inlet grille while avoiding poor air conditioning drainage and water accumulation in the drain pipe has become a technical problem that needs to be solved urgently in this field.

[0029] In the phenomenon of "compression rod instability", the straight rod under axial pressure is called a compression rod. The compression rod maintains its original equilibrium state under pressure, which is called the stability of the compression rod. From the perspective of strength, the compression rod can work normally as long as it meets the strength conditions of axial compression. There is a critical value F for the pressure F. cr , when F<F cr When F≥F cr When the critical value F is less than 0.05, the "compression rod instability" phenomenon will occur, resulting in a large bending. The bending will reduce the bending stiffness and cause further deformation of the component, that is, the component loses stability. cr The calculation formula is F cr =Π 2 EI / L 2 , where E is the elastic modulus of the component, I is the section moment of inertia of the component, and L is the overall length of the component. The elastic modulus E is related to the material of the component. For the air inlet grille, considering the overall weight and strength of the air inlet grille, the material of the air inlet grille should not be changed. Considering the layout space of the internal components of the air conditioner and the overall height of the air conditioner, the overall length of the air inlet grille should not be adjusted. Therefore, the elastic modulus E of the air inlet grille and the overall length L of the component are determined to be unchanged. Therefore, the critical value F for the occurrence of compression rod instability is crIt is only related to the cross-sectional inertia moment I of the air inlet grille. Based on this, the following implementation methods are proposed.

[0030] like Figures 1-4 As shown, in order to solve the problem that the existing air inlet grille 1 of the air conditioner cannot ensure the structural strength of the air inlet grille while avoiding poor drainage of the air conditioner and water accumulation in the drain pipe, the first area 11 of the air inlet grille 1 of the air conditioner of the utility model is installed with a maintenance plate 111, and the area between the first area 11 and the bottom of the air inlet grille is the second area 12 of the air inlet grille. The second area 12 is provided with a first reinforcing rib 121, and the first reinforcing rib 121 includes a vertical rib 1212 and a horizontal rib 1211. The vertical rib 1212 is long and arranged along the vertical direction. There are multiple vertical ribs 1212, and the horizontal rib 1211 is connected between the multiple vertical ribs 1212.

[0031] In the case of adopting the above embodiment, since the air inlet grille 1 of the air conditioner of the present invention is provided with the first reinforcing rib 121 on the second area 12 between the maintenance plate 111 and the bottom of the air inlet grille, and the first reinforcing rib 121 is provided in a staggered manner with vertical ribs 1212 and transverse ribs 1211, the vertical ribs 1212 and transverse ribs 1211 respectively support the forces in the vertical and horizontal directions exerted on the second area 12, thereby increasing the sectional inertia moment of the second area 12, thereby increasing the critical pressure value F of the second area 12 at which the compression rod instability occurs. cr This improves the overall structural strength of the second region 12, enabling it to better support the entire air conditioner air inlet grille 1. This resolves the issue of weakened support strength or even deformation at the bottom of the air inlet grille caused by the upward movement of the maintenance panel 111 to prevent poor air conditioning drainage and water accumulation in the drain pipe. Furthermore, regarding the air inlet grille's moment of inertia I, although the aforementioned method of increasing the moment of inertia of the second region 12 by providing the first reinforcing rib 121 has been described, those skilled in the art can also increase the second region 12's moment of inertia by increasing its thickness. These approaches fall within the technical principles of the present invention and are therefore encompassed within its scope of protection.

[0032] In the above embodiment, it is mentioned that the second area 12 of the air inlet grille is provided with staggered horizontal ribs 1211 and vertical ribs 1212 to improve the overall structural strength and deformation resistance of the second area 12. Considering that in the area where the air inlet grille is unstable, the area closer to the bottom is subjected to greater pressure, and thus the possibility of the pressure rod being unstable is also the greatest, in this embodiment, as shown in FIG. Figures 1-4As shown, a second reinforcing rib 122 is provided between the second area 12 and the bottom of the air inlet grille, one end of the second reinforcing rib 122 is connected to the second area 12, and the other end is connected to the bottom of the air inlet grille, and the side surface of the second reinforcing rib 122 is provided as a right triangle, and the two right-angled sides of the right triangle are respectively connected to the second area 12 and the bottom of the air inlet grille.

[0033] In the case of adopting the above embodiment, since the connection between the second area 12 and the bottom of the air inlet grille is located lower than the second area 12, the pressure F at this location exceeds the critical pressure value F. cr The probability of failure is higher. By providing a second right-angled triangle-shaped reinforcing rib 122 between the second region 12 and the bottom of the air inlet grille, on the one hand, the moment of inertia of the section at the connection between the second region 12 and the bottom of the air inlet grille is increased, thereby improving the critical pressure value that the connection between the second region 12 and the bottom of the air inlet grille can withstand. On the other hand, the hypotenuse of the right-angled triangle can also provide a certain support for the second region 12, thereby further ensuring the structural stability of the second region 12. In addition, those skilled in the art may also connect the bottom end of the vertical rib 1212 to the bottom of the air inlet grille and provide an outer extension 12121 at the bottom end of the vertical rib 1212, thereby increasing the connection surface between the bottom end of the vertical rib 1212 and the bottom of the air inlet grille and improving the strength of the vertical rib 1212 structure in the second region 12. Those skilled in the art may also provide the outer extension 12121 at the bottom end of the vertical rib 1212 to a triangle, cone, or truncated cone, etc. These changes do not exceed the technical principles of the present invention and are therefore included in the scope of protection of the present invention.

[0034] like Figures 1-4As shown, in a possible embodiment, the first area 11 is used to install the installation frame 112 of the maintenance panel 111 and is provided with an outer flange 1121. The outer flange 1121 is arranged on the side of the installation frame 112 along the vertical direction. A third reinforcing rib 1122 is connected between the outer flange 1121 and the installation frame 112. The third reinforcing rib 1122 is in the shape of a right triangle. The border of the installation frame 112 is bent toward the inside of the air conditioner. A downwardly protruding pin 1111 is provided at the bottom of the maintenance panel 111. The end of the pin 1111 is provided with a guiding inclined surface. Correspondingly, a socket is provided on the bottom edge of the installation frame 112, and the pin 1111 can be inserted into the socket. Transverse reinforcing ribs 1112 and longitudinal reinforcing ribs 1113 are also provided on the maintenance panel 111. A clamping claw 1114 is provided on the side of the maintenance plate 111, and the clamping claw 1114 includes a guiding slope and a clamping groove 11141 connected to the guiding slope. A corresponding clamping hole 1123 is provided on the side of the mounting frame 112. The clamping claw 1114 can enter under the guidance of the guiding slope and clamp the clamping groove 11141 on the clamping hole 1123. A clamping protrusion 1115 is also provided on the top of the maintenance plate 111, and a corresponding buckle 1124 is provided on the top of the mounting frame 112. The clamping protrusion 1115 can be clamped on the buckle 1124.

[0035] When the above embodiment is adopted, during the installation process of the air inlet grille 1 of the air conditioner of the present invention, the pin 1111 protruding downward from the bottom of the maintenance plate 111 is first inserted into the socket on the bottom edge of the mounting frame 112. During this process, the guiding slope at the end of the pin 1111 first contacts the socket, and under the guidance of the guiding slope, the maintenance plate 111 is continued to be pushed downward to insert the pin 1111 into the socket on the bottom edge of the mounting frame 112, thereby realizing the installation connection between the bottom of the maintenance plate 111 and the bottom of the mounting frame 112. Then push the maintenance plate 111 toward the mounting frame 112. At this time, the maintenance plate 111 rotates around the connection between the pin 1111 and the socket until the guiding slope of the clamping claw 1114 on the side of the maintenance plate 111 contacts the clamping hole 1123 on the side of the mounting frame 112. The maintenance plate 111 continues to rotate along the rotation axis under the contact between the clamping hole 1123 and the guiding slope. When the clamping hole 1123 enters the clamping groove 11141 connected to the guiding slope, the side wall of the clamping hole 1123 is clamped in the clamping groove 11141, thereby achieving fixed installation of the maintenance plate 111 and the side of the mounting frame 112. During the process of the maintenance plate 111 rotating around the rotation axis, the clamping protrusion 1115 on the top of the maintenance plate 111 contacts the clamping buckle 1124 on the top of the mounting frame 112, and as the maintenance plate 111 continues to rotate, the inner wall of the clamping buckle 1124 is slightly deformed under the pressure of the clamping protrusion 1115, and the clamping protrusion 1115 continues to be inserted inward until the head of the clamping protrusion 1115 passes through the inner wall of the clamping buckle 1124. At this time, the inner wall of the clamping buckle 1124 rebounds to clamp the head of the clamping protrusion 1115 to achieve the installation of the maintenance plate 111 and the top of the mounting frame 112.

[0036] The advantages of the above embodiment are that, by providing an outer flange 1121 on the mounting frame 112 and disposing a third right-angled triangle-shaped reinforcement rib 1122 between the outer flange 1121 and the mounting frame 112, the installation of the maintenance panel 111 is facilitated while also increasing the connection strength between the outer flange 1121 and the mounting frame 112, thereby enhancing the support capability of the mounting frame 112's side edges for the air inlet grille. By providing a snap-fit ​​installation method between the maintenance panel 111 and the mounting frame 112, the maintenance panel 111 is easily assembled and disassembled. Furthermore, by providing the transverse reinforcement ribs 1112 and the longitudinal reinforcement ribs 1113 on the maintenance panel 111, the structural strength and pressure-bearing capacity of the maintenance panel 111 are enhanced. By bending the frame of the mounting frame 112 toward the interior of the air conditioner, the overall structural strength of the air inlet grille is further enhanced.

[0037] It should be noted that the above-mentioned embodiment is only used to illustrate the principle of the present invention and is not intended to limit the scope of protection of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above-mentioned structure so that the present invention can be applied to more specific application scenarios.

[0038] In addition, the present invention also provides an air conditioner having the air inlet grille 1 of any one of the above embodiments.

However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
