Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Referring to fig. 1, a schematic view of a wall penetrating pipe is shown.

The air conditioner with the fresh air function is provided with the fresh air module, the fresh air module is located indoors, and the fresh air module extends to the outdoors through a pipeline and exchanges with outdoor air. The fresh air pipe comprises a fresh air module joint A, a fresh air pipe B located at an indoor section, a connector C of a fresh air pipe D passing through a wall section, a fresh air pipe D passing through the wall section and a rain-proof cap E located outdoors. In general, the connection between the fresh air pipe B of the indoor section and the fresh air pipe D of the wall penetrating section requires a connector C for connection due to the limitation of the aperture of the wall penetrating tool and the size of the wall hole.

For example, in the wall-mounted fresh air conditioner, the diameter of the fresh air duct D at the wall-through section is affected by the size of the wall hole, for example, the diameter of the wall hole is 63mm, and the inner diameter of the fresh air duct D at the wall-through section is 30mm, but in order to ensure the fresh air volume, the inner diameter of the fresh air duct B at the indoor section is 40 mm. Because the internal diameter of the fresh air pipe D of the wall penetrating section is smaller, the ventilation volume of fresh air can be influenced. And because the internal diameter of the fresh air pipe D of the wall penetrating section is not matched with the external diameter of the fresh air pipe B of the indoor section, the fresh air pipes can not be directly connected, and a connector C is also needed. Therefore, connecting parts are too many, the difficulty and complexity in the installation process are increased, the occurrence probability of the conditions that the parts are abnormal and damaged due to the fact that more parts are connected is increased, and the use experience of a user is reduced.

In another embodiment, referring to fig. 2, a schematic view of a wall penetrating pipe, which may be applied to an air conditioner, is shown. This wall bushing includes:

the pipe body 1, the body constitutes the inlet air channel who wears the wall section, and when the wall pipe worn to establish in the wall hole, the body 1 constitutes the inlet air channel who wears the wall section, and the body 1 wears to establish in the wall hole.

And the end part is provided with a first end 201 and a second end 202 which are opposite, wherein the first end 201 is communicated with the indoor side, and the second end 202 is communicated with the outdoor side.

The maximum radial width of the first end 201 is smaller than the maximum radial width of the tubular body 1, and the maximum radial width of the second end is smaller than or equal to the maximum radial width of the tubular body 1. The maximum radial width may be a dimension at which the width is maximum in a cross section in the radial direction of the pipe body, that is, the maximum width of the pipe body 1 in the radial direction.

The pipe body 1 may be a circular pipe, a square pipe, an elliptical pipe, or the like. For example, when the pipe body 1 is a circular pipe, the maximum radial width of the pipe body 1 is the diameter of the cross section of the circular pipe. When the pipe body 1 is a square pipe, the maximum radial width of the pipe body 1 is the length of the maximum diagonal line of the cross section of the square pipe. When the pipe body 1 is an elliptical pipe, the maximum radial width of the pipe body 1 is the major axis of the ellipse.

When the second end is a second connecting part, the maximum radial width of the second end is smaller than that of the pipe body 1, so that the connection with other parts can be facilitated. When the second end is not the second connection portion and has the air inlet 2011, the maximum radial width of the second end is equal to the maximum radial width of the pipe body 1.

The outer diameter of the pipe body 1 can be adjusted according to the size of the wall hole and is matched with the size of the wall hole. If the diameter of the wall hole is 63mm, the outer diameter of the pipe body 1 can be about 60mm-62 mm; if the wall hole diameter is 80mm, the outer diameter of the pipe body 1 may be 78mm to 79 mm. If the problem of condensation is considered, the outer diameter of the pipe body 1 can be further reduced to ensure the sponge pasting space.

In another embodiment, the tube 1 is a linear tube, the first end 201 is in an open state, the first end 201 has a first connecting thread 2011, the first connecting thread 2011 can be directly connected to the indoor tube, and the size and shape of the first connecting thread 2011 match with the threads on the indoor tube. The second end is provided with an air inlet 2021,

therefore, when the indoor pipe body and the wall penetrating pipe are connected, other connecting devices are not needed, the wall penetrating pipe and the indoor pipe body can be directly connected, simplicity and convenience are achieved, and installation complexity is reduced.

The width of the tube body 1 is larger than the diameter of the first end 201, and since the cross section of the tube body 1 is D-shaped, one surface is a plane corresponding to a linear section, i.e., a straight section, of the D-shaped cross section. The width of the straight section is the diameter of the first end 201.

Referring to fig. 5, a schematic view of the pipe 1 connected to the indoor pipe a is shown.

In another embodiment, the cross section of the pipe body 1 may also be other shapes, not limited to D-shape, and may be determined according to actual use requirements.

The air inlet 2021 is located on the side of the second end 202, and the air inlet 2021 faces downward. The air inlet 2021 faces downward, which can reduce the probability of impurities entering the pipe body 1, for example, in rainy days, can reduce the probability of raindrops entering the pipe body 1.

The end surface of the second end 202 is in a closed state, so that air can be fed through the air inlet 2021, and the positions of the wall penetrating pipe except the openings of the air inlet 2021 and the first end 201 are closed, so as to reduce the possibility that other objects enter the pipe body 1.

In another embodiment, referring to fig. 2 and 3, the second end 202 has an air inlet 2021, and the air inlet 2021 includes a plurality of round holes, and by providing the plurality of round holes at the air inlet 2021, part of the impurities can be blocked from entering the tube body, so as to reduce the possibility of the impurities entering the tube body 1, and at the same time, ensure the ventilation amount.
