As shown in fig. 1, a wall-mounted type air conditioner according to the present application may include, for example, a wall-mounted panel 100, an upper base 200, a lower base 300, and a protection panel 400.

The wall hanging panel 100 is a part for mounting the air conditioner according to the application to a wall, and when the air conditioner is mounted, it is first fixed to the wall and then other components of the air conditioner are mounted on the wall hanging panel 100, so that the wall hanging panel 100 may include a plurality of panel coupling features. A number of peg board attachment features will be discussed in detail below.

The upper base 200 is used to house a heat exchanger therein and has a hanging feature, such as one or more slots 210. Upper base 200 may thus be removably hung from at least one of the plurality of peg board attachment features of peg board 100, such as upper hem 110. As shown in fig. 1, for example, the upper flaps 110 may be two upper flaps 110 symmetrically disposed in a horizontal direction after installation. In addition, the upper folding edge 110 may be one arranged at the horizontal center, or three evenly distributed in the horizontal direction, and at this time, the number of the hanging features of the upper base 200 is matched with that.

The lower base 300 serves to receive the air duct assembly therein, and is detachably coupled to the upper base 200. Because the lower base 300 is detachably connected to the upper base 200, the lower base 300 can be detached from the upper base 200 according to the use requirement, and the air duct assembly and the related components contained therein can be cleaned and repaired. After the cleaning and maintenance are completed, the base 300, together with the air duct assembly and the like received therein, may be mounted on the upper base 200 to form a complete air conditioner.

The protection plate 400 may include a cavity 410, an upper sidewall 420, and a lower sidewall 430. The cavity 410 may accommodate the wire bundle 500 to protect the wire bundle 500 from being damaged by friction during the process of assembling and disassembling the lower base 300. The upper and

The protection plate 400 may be assembled with the upper base 200 and the lower base 300. The protective panel 400 also includes a crimp feature to make a crimp connection with at least one of the plurality of peg board connection features on the peg board 100 when the air conditioner is installed. The pressure-contact connection is a connection method in which, when the air conditioner is mounted, the air conditioner body is hung on, for example, the upper flange 110 of the wall-hanging panel 100 by the hanging feature of the upper base 200, and then the air conditioner body is pressed to connect the protection panel 400 and the wall-hanging panel 100.

According to an embodiment of the present application, the upper base 200 and the heat exchanger therein, the lower base 300 and the air duct assembly therein, and the protection plate 400 and the pipe bundle 500 therein may be assembled together as an integral assembly for packaging, transporting, warehousing or installation on the wall cladding 100. This may greatly facilitate packaging, shipping, warehousing or installation of the wall-mounted air conditioner. For example, if the protection plate 400 is not assembled with the air conditioner body during the assembly, it is very difficult to fix the wire harness 500 inside the air conditioner body to the wall-hanging plate 100 through the protection plate 400 during the installation of the air conditioner, which affects the quality of the assembly and increases the installation time, if possible.

According to an embodiment of the present application, when installed, the integrated assembly may be hung on the upper hem of the wall cladding 100 and rotatable about the upper hem of the wall cladding 100.

The present application can achieve the following advantageous effects.

A wall-mounted air conditioner according to the present application includes a wall-hung panel 100 fixed on a wall when installed, an upper base 200 accommodating a heat exchanger therein, a lower base 300 accommodating a duct assembly therein, and a protection panel 400 including a cavity 410 accommodating a bundle of pipes 500, and an upper sidewall 420 of the protection panel 400 may be connected with the upper base 200, a lower sidewall 430 thereof may be detachably connected with the lower base 300, and the lower sidewall 430 thereof includes a crimping feature to crimp with at least one of a plurality of panel-connecting features on the wall-hung panel 100. Therefore, the wall-mounted air conditioner according to the present application may be assembled as a whole at the time of manufacture, and be hooked and pressed with the wall-mounted panel 100 at the time of installation, thereby facilitating installation. Since the cavity 410 of the protection plate 400 completely receives the bundle of pipes 500, the upper sidewall 420 thereof is coupled with the upper base 200, and the lower sidewall 430 thereof is mounted while being pressed against the wall-hanging plate 100, the bundle of pipes 500 is disposed between the protection plate 400 and the wall-hanging plate 100. Because the lower base 300 is detachably connected to the upper base 200 and the protection plate 400, the lower base 300 can be easily detached from the upper base 200 and the protection plate 400, thereby facilitating the detachment and cleaning of the air duct assembly and the like received on the lower base 300. Since the pipe bundle 500 is disposed between the protection plate 400 and the wall hanging plate 100, the lower base 300 and the duct assembly received therein are not damaged even if they are repeatedly mounted and dismounted, and the pipe cutting phenomenon can be completely prevented.

The above embodiments are merely illustrative, and not restrictive, and those skilled in the relevant art can make various changes and modifications without departing from the spirit and scope of the present application, and therefore all equivalent technical solutions also fall within the scope of the present application, and the scope of the present application is defined by the appended claims.
