Embodiment Construction

[0025] figure 1 is a schematic structural diagram of a window air conditioner according to an embodiment of the present invention. Such as figure 1 shown, and refer to figure 2 and image 3 , the embodiment of the present invention provides a window type air conditioner, the window type air conditioner may include a housing 20, and a compressor located in the housing 20, a condenser, a throttling device, an evaporator 30, used for heat dissipation of the condenser The centrifugal fan and the cross-flow fan 40 for blowing cold wind indoors. Specifically, the front end of the casing 20 may have an air inlet 21 and an air outlet 22 , and the air outlet 22 may be located above the air inlet 21 . For example, the case 20 may include a front case, and the front case may include a vertical plate, and an upper curved plate located above the vertical plate. The air inlet 21 can be arranged on the vertical plate; the air outlet 22 can be arranged on the upper curved plate, so that...

Abstract

The invention provides a window type air conditioner. The window type air conditioner comprises a shell body and a cross-flow fan. The front end of the shell body is provided with an air inlet and an air outlet located above the air inlet. The cross-flow fan is arranged in the shell body and provided with a wind wheel, a volute and a volute tongue which is located on the front side of the volute. The air inlet and the air outlet communicate through a fan air channel limited by the volute and the volute tongue. The projection, in the plane perpendicular to the rotation axis of the wind wheel, of the inner surface of the volute forms the volute profile line of the volute, and the volute profile line is divided into an upper section and a lower section through the point, closest to the rotation axis of the wind wheel, on the volute profile line. In addition, the upper section comprises three circular arc sections connected sequentially and smoothly. According to the window type air conditioner, due to the fact that the volute profile line of the volute comprises the three circular arc sections, the special streamline air channel design structure enables air inflow and air outflow of the window type air conditioner to be smoother, and accordingly noise generated by the window type air conditioner is significantly lowered.

Description

technical field [0001] The invention relates to air conditioning technology, in particular to a window type air conditioner. Background technique [0002] The window air conditioner is usually installed on the wall. One part of the window air conditioner is located outdoors, and the other part is located indoors. The casing of the outdoor part is equipped with compressors, outdoor heat exchangers and other structures, and is located in the casing of the indoor part. Equipped with structures such as indoor heat exchangers, compared to split units, window air conditioners are integrated devices for the refrigeration systems on the indoor and outdoor sides. However, the noise generated by the existing window air conditioners on the indoor side is generally above 50 decibels, which is not suitable for use in places that require quietness. Contents of the invention [0003] The object of the present invention is to overcome at least one defect of the existing window air condit...
