Description

Four sides air conditioner

technical field

The invention relates to an air conditioner, in particular to a four-sided air outlet air conditioner with a large air outlet range and a wide coverage.

Background technique

As shown in FIG. 1, the air conditioner has a base 1, a rear case with an open front and connected to the upper part of the base 1, and a front case 4 connected to the front of the rear case. The two opposite sides of the front case 4 are inclined surfaces, and the upper air outlet 4a is located on the upper part 5 of the front case, the side air outlets 4b and 4c are located on the left and right sides of the upper part of the front case, and the side air inlets 4d and 4e are located on the front case left and right sides of the lower body.

Chinese patent 200410090303.3 discloses an indoor unit of a cabinet air conditioner, the structure of which is shown in FIG. 2 . There are three air inlets on the housing of the indoor unit of the air conditioner, including the side air inlets 4' and 5' located on both sides of the front panel 1', and the front air inlet 6' located on the lower base of the front panel 2', which are used to suck in indoor air. into the shell; there are three air outlets on the shell, which are used to discharge the air that has undergone heat exchange in the shell. As can be seen from Figure 2, the three air outlets of the indoor unit of the air conditioner and one front air outlet 9' are located on the top wall of the indoor unit, and there is a cover plate 10' at the opening. When the air conditioner is turned on, the cover plate 10' is turned upwards , the front air outlet is open; two side air outlets 7' and 8' are respectively located on both sides of the front panel of the indoor unit.

In the above technical solution, the setting of the air outlet has the following problems:

The air outlet is set on the upper or top of the front of the indoor unit, resulting in a narrow range of air supply up and down. Due to the obstruction of the top wall of the indoor unit, the air outlet range of the upper air outlet can only reach the space above the top wall of the indoor unit, and the upper and lower air outlet angles are impossible. If it exceeds 90°, the air supply effect at the lower position directly in front is not good.

In view of this, the present invention is proposed.
