[0025] The present application provides an indoor unit of a wall-mounted air conditioner.

[0026] In some embodiments of the present application, as shown in FIGS. 1 to 4, the indoor unit of the wall-mounted air conditioner includes: a housing, which includes a chassis 100 defining an air duct having an air outlet; a face frame 200; an installation plate disposed at an end of the air outlet along a length direction of the air outlet; a motor assembly 300 disposed at a side of the installation plate opposite to the air outlet; a first extending plate 110 disposed on the chassis 100, extended along the length direction of the air outlet and disposed above the motor assembly 300, where the first extending plate 110, the installation plate, and the face frame 200 are enclosed to define an accommodating space including an opening opposite to the installation plate; and a rats-proof plate 210 disposed on an inner surface of the face frame 200 and extending rearwardly, where the rats-proof plate 210 is configured to cover at least a part of the opening, and the motor component 300 is disposed between the rats-proof plate 210 and the air outlet. The indoor unit of the wall-mounted air conditioner generally may include an air guiding structure for guiding air outlet in the air duct, and the motor assembly 300 may be connected with the air guiding structure and drive the air guiding structure. In some embodiments, the motor assembly 300 may include a motor and a speed reduction assembly. The motor assembly 300 and the wires connecting the motor assembly 300 are disposed in the accommodating space, and the wires are at risk of being bitten by the rats when the rats enters the installation space of the motor assembly 300 through a gap between the face frame 200 and the chassis 100.

[0027] According to the technical solution of the present application, the accommodating space is defined by enclosing the first extending plate 110, the installation plate and the face frame 200, and the motor assembly 300 is disposed in the accommodating space. The first extending plate 110 is disposed above the motor assembly 300 and may prevent the rats from entering the accommodating space from the top of the motor assembly 300. A rats-proof plate 210 is further provided for covering at least a part of the opening of the accommodating space, so as to prevent the rats from entering the accommodating space from the opening.

[0028] Specifically, in the present application, the first extending plate 110 is connected with the installation plate such that no gap is left between the first extending plate 110 and the installation plate, and the anti-rat and anti-insect function of the first extending plate 110 may be reinforced.

[0029] The structure of the rats-proof plate is not limited to the above technical solution. In other embodiments, the rats-proof plate may totally cover the opening, thereby preventing the rats from entering the accommodating space from the opening and damaging the air conditioning components in the accommodating space.

[0030] Further, in some embodiments, as shown in FIG. 2, the minimum gap between the motor assembly 300 and the face frame 200 is at most 10 mm, and the rats cannot get through the gap when the gap is at most 10 mm. The gap between the face frame 200 and the motor assembly 300 is controlled to be at least 0 mm and at most 10 mm, so that the rats may be effectively prevent from getting through the gap between the face frame 200 and the motor assembly 300.

[0031] Further, in some embodiments, as shown in FIG. 2, the gap between the rats-proof plate 210 and the motor assembly is at most 10 mm. The gap between the rats-proof plate 210 and the motor assembly 300 is small, which can effectively prevent the rats from getting through the gap between the rats-proof plate 210 and the motor. The outer housing of the motor and the rats-proof plate 210 may act together to prevent the rats from entering the space between the rats-proof plate 210 and the installation plate from the rear side of the motor and from a side away from the air duct, so that the wires of the motor assembly 300 installed in the space between the rats-proof plate 210 and the mounting plate may be prevented from being bitten by the rats.

[0032] Further, in some embodiments, as shown in FIG. 2, the gap between the first extending plate 110 and the rats-proof plate 210 is at most 10 mm. The gap between the first extending plate 110 and the rats-proof plate 210 is small, which can effectively prevent the rats from getting through the gap between the first extending plate 110 and the rats-proof plate 210. A gap is formed between the rats-proof plate 210 and the first extending plate 110, so that the fit precision between the rats-proof plate 210 and the first extending plate 110 is low, which is favorable for reducing the processing difficulty of the rats-proof plate plate 210. The embodiment is not limited to the above technical solution. In other embodiments, a sealing strip may be provided at an edge of the rats-proof plate 210 adjacent to the first extending plate 110, and the sealing strip abuts against the rats-proof plate, so that the gap between the rats-proof plate 210 and the first extending plate 110 may be eliminated to enhance the anti-insects effect of the rats-proof plate 210.

[0033] Further, in some embodiments, as shown in FIG. 2, the first extending plate 110 extends rearwardly and downwardly. The first extending plate 110 is disposed above the motor assembly 300. Therefore, the first extending plate 110 extends downwardly to facilitate reducing the minimum gap between the motor assembly 300 and the first extending plate 110, so that the outer housing of the motor assembly 300 may cooperate with the first extending plate 110 to enhance the anti-rats effect.

[0034] Further, in some embodiments, as shown in FIG. 2, the indoor unit of the wall-mounted air conditioner further includes: a second extending plate 120 disposed on the installation plate, where the second extending plate 120 is extended along the length direction of the air outlet and disposed behind the motor assembly 300; and a transition plate 130 disposed on the installation plate, where the transition plate 130 is connected to the first extending plate 110 and the second extending plate 120. The second extending plate 120 is configured to prevent the rats from entering the accommodating space from the rear side of the motor assembly 300, and the transition plate 130 blocks the gap between the first extending plate 110 and the second extending plate 120, thereby enhancing the anti-rats effect. On the other hand, the second extending plate 120 and the transition plate 130 may act together to enhance the mechanical strength of the first extending plate 110.

[0035] Further, in some embodiments, as shown in FIG. 2 and FIG. 3, the transition plate 130 has a stepped shape protruding towards the motor assembly 300, which is advantageous to reduce the gap between the transition plate 130 and the motor assembly 300, so that it is difficult for the rats to pass between the transition plate 130 and the motor assembly 300, so that the transition plate 130 has a stronger anti-rats effect.

[0036] Further, in some embodiment, as shown in FIG. 2 and FIG. 3, the transition plate includes: a first step surface 131 extending downwardly and connecting the first extending plate 110; and a second step surface 132 extending downwardly and rearwardly and connecting the first step surface 131 and the second extending plate 120. The second step surface 132 is inclined downwardly and rearwardly, so that the distance between the connection of the second step surface 132 and the second extending plate 120 and the motor assembly 300 is reduced, which is advantageous for improving the anti-rats effect of the transition plate 130 and the second extending plate 120.

[0037] The first extending plate 110, the second extending plate 120, and the transition plate 130 are not limited to the above technical solutions. In other embodiments, the transition plate 130 may be curved to smoothly transit the first extending plate 110 and the second extending plate 120, which may facilitate reducing the distance between the connection of the first extending plate 110 and the transition plate 130 and the motor assembly 300, and reducing the distance between the connection of the transition plate 130 and the second extending plate 120 and the motor assembly 300, which enhances the anti-rats effect.

[0038] Further, in some embodiments, as shown in FIG. 2, the minimum gap between the second extending plate 120 and the face frame 200 is at most 10 mm, and the face frame 200 and the second extending plate 120 may act together to block the rats. The rats cannot get through the gap between the face frame 20 and the second extending plate 120 because the minimum gap between the second extending plate 120 and the face frame 200 is small after the face frame 200 and the chassis 100 are assembled.

[0039] Further, in some embodiments, as shown in FIG. 2 and FIG. 3, the chassis 100 further includes: an end plate 140 connecting the installation plate and the first extending plate 110, where the end plate 140 is disposed at a side of the installation plate adjacent to the motor assembly 300 and in front of the first extending plate 110. The end plate 140 is connected with the first extending plate 110 to increase the anti-rats range. In some embodiments, the end plate 140, the first extending plate 110, the transition plate 130, the first extending plate 110, and the face frame 200 enclose the motor assembly 300 to define a protection circle which has the advantage of comprehensive anti-rats angle.

[0040] Further, in some embodiments, as shown in FIG. 2, the gap between the rats-proof plate 210 and the end plate 140 is at most 10 mm. The rats-proof plate 210 is disposed below the end plate 140, and the rats-proof plate 210 extends from an inner side of the face frame 200. The gap between the rats-proof plate 210 and the end plate 140 is controlled to be at most 10 mm, so as to prevent the rats from getting through the gap between the rats-proof plate 210 and the end plate 140. In some embodiments, the rats-proof plate 210 is connected to the face frame 200, and the end plate 140 is disposed on the chassis 100, so that a gap is provided between the end plate 140 and the rats-proof plate 210, which is advantageous for decrease the fit precision between the end plate 140 and the rats-proof plate 210, thereby reducing the processing precision of the rats-proof plate 210, and facilitating the assembly of the face frame 200 and the chassis 100. The structure of the rats-proof plate 210 and the end plate 140 may not limited to the above technical solutions. In other embodiments, a sealing strip may be provided at an edge of the rats-proof plate 210 adjacent to the end plate 140, and the sealing strip abuts against the end plate 140, so that the gap between the rats-proof plate 210 and the end plate 140 may be eliminated to enhance the anti-insects effect of the rats-proof plate 210.

[0041] Further, in some embodiments, a strengthening rib may be provided at the connection between the rats-proof plate 210 and the face frame 200, and the strengthening rib has the function of strengthening the mechanical strength of the rats-proof plate 210, which is advantageous for enhancing the resistance against the rats of the rats-proof plate 210, and enhancing the reliability of the rats-proof plate 210.

[0042] Further, in some embodiments, the indoor unit of the wall-mounted air conditioner further includes an electric control box disposed at one side of the air duct, and the motor assembly 300 is disposed at the other end of the air duct. In order to make reasonable use of the installation space of the indoor unit of the wall-mounted air conditioner, the motor assembly 300 configured to drive the air guiding structure and the electric control box are respectively disposed on both sides of the air duct, and the air outlet is disposed closer to the center of the indoor unit of the wall-mounted air conditioner, which is advantageous for making the indoor unit of the wall-mounted air conditioner have a more aesthetically appealing shape.

[0043] Further, in some embodiments, the indoor unit of the wall-mounted air conditioner further includes a fresh air module disposed inside the housing and at a side of the first extending plate 110 away from the air duct. The fresh air module is configured to introduce fresh air into the room, while the rats may be easily get into the motor assembly 300 through the fresh air module, so the rats-proof plate 210 is more important in the indoor unit of the wall-mounted air conditioner with the fresh air module.

[0044] In some embodiment, as shown in FIG. 2 and FIG. 4, the rats-proof plate 210 extends rearwardly to one side of the motor assembly 300, and does not continue to extend to the second extending plate 120. The rats-proof plate 210 and the outer housing of the motor may act together to block the rats. In addition, the length of the rats-proof plate 210 is controlled, which may prevent the rats-proof plate 210 from being too long to reduce the mechanical strength, and reduce materials and manufacturing costs of the rats-proof plate 210.
