Referring to fig. 4 to 6, fig. 4 is a schematic structural diagram of an air conditioner 100 according to another view angle of the present application, fig. 5 is an enlarged view of fig. 4 at C, and fig. 6 is a schematic structural diagram of a support frame 6 according to an embodiment of the present application. In some embodiments of the application, a support shelf 6 is provided at the bottom wall of the first housing chamber 2. The support frame 6 comprises a support 7. The top of the support 7 is provided with a support surface 8. The support surface 8 is an inclined surface at a distance L from the top wall of the first receiving chamber 2. L gradually decreases in a direction away from the mounting opening 3.

As shown in fig. 6, the support surface 8 is a slope, the end having the greatest distance from the top of the first accommodating chamber 2 is a low level end, and the end having the smallest distance from the top of the first accommodating chamber 2 is a high level end.

When the electric control box 21 is inserted into the first accommodating cavity 2 and the electric control box 21 is positioned at the low position of the supporting surface 8, a gap exists between the top of the electric control box 21 and the top wall of the first accommodating cavity 2. This makes it possible to make the electric control box 21 less obstructed and to push the electric control box 21 more labor-saving when the electric control box 21 is just inserted into the mounting opening 3. When the electronic control box 21 moves further toward the first accommodating chamber 2, as the electronic control box 21 advances into the first accommodating chamber 2, a gap exists between the electronic control box 21 and the top wall of the first accommodating chamber 2 to contact and then to abut, and the abutting force is gradually increased.

Thus, the bottom of the electric control box 21 is supported by the supporting surface 8, so that the convenience of installation of the electric control box 21 can be improved, the initial installation of the electric control box 21 is less hindered, and the electric control box 21 can be pushed into the first accommodating cavity 2 more smoothly. But also can make the electric control box 21 and the top wall of the first accommodating cavity 2 abut through the high-position end of the supporting surface 8, thereby fixing the electric control box 21 between the top wall and the bottom wall of the first accommodating cavity 2, improving the convenience of the installation of the electric control box 21 and further improving the installation efficiency of the electric control box 21.

Referring to fig. 6, in some embodiments of the present application, the supporting frame 6 further includes a limiting member 9. The limiting piece 9 is arranged on one side of the supporting piece 7 away from the mounting opening 3. The side of the limiting piece 9 facing the mounting opening 3 is contacted with the side of the electric control box 21 facing away from the mounting opening 3.

In practice, the limiting member 9 is raised above the support member 7 in order to bring the limiting member 9 into contact with the electronic control box 21. Specifically, the distance of the stopper 9 from the top wall of the first accommodation chamber 2 is greater than the distance of the high-order end from the top wall of the first accommodation chamber 2, which causes a stepped surface to be formed between the stopper 9 and the support 7.

When the electric control box 21 is installed, the electric control box 21 is pushed into the first accommodating cavity 2 until the electric control box 21 is in contact with the limiting piece 9, so that the position, opposite to the limiting piece 9, of the electric control box 21 is installed in place. Thereby realize carrying out the location to an installation direction of automatically controlled box 21 based on locating part 9 to can promote the location accuracy when automatically controlled box 21 installs.
