In the related art, the air conditioner needs to be provided with a rat-proof structure because the problem that a rat enters the vicinity of the electric control box from the position of the end cover pipe to break the electric wire and cause short circuit frequently occurs in the indoor unit of the air conditioner. The scheme adopted at present is that a plastic part rat guard is usually added at the wire outlet of the electric control box. However, the rat guard is manufactured by designing a special plastic mold, the mold is high in cost, and the rat guard is required to be installed on the shell through bolt connection or buckle connection during installation, so that a connecting hole or a buckle position needs to be formed in the corresponding position of the shell, the processing cost is high, and the installation is inconvenient. In order to solve at least one of the above technical problems, the present invention provides a ratproof structure which is low in cost and convenient to install.

Referring to fig. 1 to 3, the ratproof structure according to the embodiment of the first aspect of the present invention includes a plate body 100, wherein the plate body 100 is made of an elastic material, and the elastic material may be pearl wool, or PE sponge, or PU sponge, or EPS foam. In a specific embodiment, the plate body 100 is made of pearl cotton, which has better elasticity and lower cost, and certainly, the pearl cotton can be common pearl cotton or flame-retardant pearl cotton, so that the use is safer.

The plate body 100 is made of the elastic material, so that the cost is low, the processing is convenient, and the required shape of the plate body 100 can be obtained through simple cutting processing, so that a special die is not required to be designed for processing and manufacturing the plate body 100, and the manufacturing cost of the rat-proof structure is greatly reduced.

Referring to fig. 1 and 3, specifically, a through hole 110 is formed in a side of the middle portion of the panel body 100, the side being close to the side wall, the through hole 110 penetrating through the entire panel body 100 along the thickness direction of the panel body 100, and a drain pipe 400 of the indoor unit may be inserted into the through hole 110 and connected to a drain pan or other components. The aperture of the through hole 110 can be specifically set according to actual needs, and the aperture can be substantially the same as the outer diameter of the drain pipe 400, so that when the drain pipe 400 is arranged in the through hole 110 in a penetrating manner, the inner wall of the through hole 110 can be tightly attached to the outer wall of the drain pipe 400, a large vacancy is avoided between the inner wall of the through hole 110 and the outer wall of the drain pipe 400, and a mouse or other sundries can be prevented from entering the electric control box 300 through the vacancy.

Referring to fig. 1, the panel body 100 has a first sidewall 130, the first sidewall 130 is provided with an avoiding groove 120, and a connection line between the indoor unit and the outdoor unit and a power line 310 of the electronic control box 300 can be connected to corresponding components through the avoiding groove 120.

When the drainage pipe 400 needs to be inserted into the through hole 110, the drainage pipe 400 can be inserted into the through hole 110 along the axial direction of the through hole 110, and the drainage pipe 400 can be inserted into the through hole 110 through the gap 150 because the plate body 100 is made of elastic material such as pearl wool. During operation, the drain pipe 400 is aligned with the gap 150 and pressed in with a slight force, so that the plate body 100 is deformed at the gap 150, the gap 150 is widened, the drain pipe 400 can be clamped into the through hole 110 through the gap 150, the installation operation is more convenient, and especially when the installation space is narrow, the installation can be more flexible through the installation mode. Meanwhile, after the drain pipe 400 is clamped into the through hole 110, the plate body 100 can be limited, and the plate body 100 is prevented from moving along the radial direction of the drain pipe 400.

Referring to fig. 1, it can be understood that the drain pipe 400 is generally a circular pipe, and therefore in some embodiments of the present invention, the through hole 110 is also provided as a circular hole, and the circular hole is matched with the outer shape of the drain pipe 400, so that when the drain pipe 400 is inserted into the circular hole, the inner wall of the circular hole can be tightly attached to the outer wall of the drain pipe 400, and a large vacant space is prevented from being formed between the inner wall of the circular hole and the outer wall of the drain pipe 400, so that rats or other sundries can be prevented from entering the electronic control box 300 through the vacant space.

It can be understood that when the plate body 100 has a relatively thin thickness, the structural strength of the plate body 100 is relatively low, and the plate body 100 is easily damaged during operations such as installation and machining, and when the plate body 100 has a relatively thick thickness, the structural strength of the plate body 100 is relatively strong, so that the plate body 100 has a relatively high hardness and is not convenient to install and machine.

Therefore, through a great number of experiments by the applicant, it is found that the thickness of the plate body 100 within a certain range can provide the plate body 100 with a better structural strength, and at the same time, the processing and installation of the plate body 100 are facilitated.

Therefore, in some embodiments of the present invention, the thickness of the plate body 100 is set to be 15mm to 25mm, for example, the thickness of the plate body 100 is 20mm, at this time, the thickness of the plate body 100 is suitable, and when the thickness of the plate body 100 is within this range, the strength of the plate body 100 is not too low or too high, which facilitates the processing and installation of the plate body 100.
