Improved spiral casing structure of wall hanging air conditioner

Abstract

An improved scroll case structure of a wall-hanging air conditioner comprises an outdoor unit of the wall-hanging air conditioner and a scroll case of an indoor unit, two fans are arranged in two parallel round holes of the scroll case in parallel, arc-shaped bodies which are protrudent to the outside are respectively arranged on two outside wall surfaces of the scroll case, and a partition board which is protrudent to the outside from the bottom part of the inner wall is arranged in the middle of the two parallel round holes on the inner wall of the scroll case in the longitudinal direction. The partition board is arranged on the scroll case body by one-batch forming. As the improved scroll case structure adopts the structure, the two fans become independent fan systems between an air outlet and a heat exchanger, thereby being capable of avoiding the mutual interference between the two fans during the rotation, reducing the air quantity loss of the two fans when entering the heat exchanger and improving the heat exchange efficiency. The improved scroll case structure can ensure the air quantity needed by indoor and outdoor heat exchange and optimize the working environment.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an improved volute structure of a wall-mounted air conditioner which makes the volute structure of the wall-mounted air conditioner more reasonable and improves indoor and outdoor heat exchange efficiency. Background technique [0002] The air conditioner is a device that cools and warms the air in the indoor space after exchanging heat between the refrigerant circulating through the compressor, condenser, expansion device, and heat exchanger, and the air passing through the heat exchanger. The structure of the air conditioner includes an outdoor unit composed of a compressor, a condenser, and an expansion device, and an indoor unit composed of a fan and a heat exchanger. The outdoor unit and the indoor unit are connected to each other through refrigerant piping. [0003] The types of air conditioners are divided according to the installation position of the indoor unit, such as upright air ...

AI Technical Summary

Problems solved by technology

[0007] The volute of the above-mentioned existing wall-mounted air conditioner, because the circular holes for installing the two fans are parallel, when the two parallel fans work, after the two fans rotate at the same time, due to the mutual influence , the exhaust air volume of each fan is also affected, so that the exhaust air volume of each fan is lower than that of each fan running alone
