Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

The window type air conditioner 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings, in which the window type air conditioner 100 is generally installed on a wall in a room.

As shown in fig. 1 and 2, a window type air conditioner 100 according to an embodiment of the present invention includes a main unit 1 and a face frame 2.

As shown in fig. 1, 2 and 9, a wall hole is formed in the wall body, an annular wall sleeve 200 is arranged in the wall hole, the main unit 1 is suitable for being located in the wall sleeve 200, the face frame 2 is arranged on the front side of the main unit 1, and the outer peripheral wall of the face frame 2 is located on the outer side of the outer peripheral wall of the main unit 1 so as to be suitable for covering the front end face of the wall sleeve 200, that is, in a plane perpendicular to the front-back direction, the projection of the main unit 1 is located within the projection of the face frame 2, so that when the main unit 1 is installed in the wall sleeve 200, the part of the face frame 2 protruding out of the main unit 1 can cover the front end face of the wall sleeve 200, and thus, the face frame 2 can shield a gap between the main unit 1 and the wall sleeve 200, and the visual. The utility model discloses an in the description, when the user just to face frame 2, the direction of being close to the user is preceding, and the direction of keeping away from the user is the back.

In particular application, and with reference to FIG. 9, the wall sleeve 200 is generally a square ring structure with the front and rear ends of the wall sleeve 200 open. For example, referring to fig. 2 and 4, the main unit 1 and the face frame 2 of the window type air conditioner 100 are each formed in a substantially square shape, and the face frame 2 is positioned on the front side of the main unit 1 such that the dimension of the face frame 2 in the left-right direction and the up-down direction is larger than the dimension of the main unit 1 in the left-right direction and the up-down direction, whereby the outer peripheral wall of the face frame 2 can be made to protrude from the outer peripheral wall of the main unit 1. When the window type air conditioner 100 is installed in the wall sleeve 200, the main unit 1 is located in the wall sleeve 200, the face frame 2 is located on the front side of the wall sleeve 200, and the part of the face frame 2 protruding out of the main unit 1 can be matched with the wall sleeve 200 to cover the front end face of the wall sleeve 200, so that a user can not see the gap between the main unit 1 and the wall sleeve 200, and the whole appearance effect of the window type air conditioner body is ensured.

In the related art, there are many types of window type air conditioners 100, and in addition to a standard window type air conditioner 100 which can be mounted on a window, there is also a wall piercing machine which is relatively commonly mounted on a wall, wherein a wall hole is formed on the wall, a wall bushing 200 is installed in the wall hole, and the wall piercing machine is installed in the wall bushing 200. The wall holes are reserved in the construction process of the building, and the wall holes and the wall coverings 200 are generally classified into four types of 24 inches, 25 inches, 26 inches and 27 inches for the sake of uniform standard.
