Wall-mounted type air conditioner indoor unit

Abstract

The invention discloses a wall-mounted type air conditioner indoor unit. The wall-mounted type air conditioner indoor unit comprises a shell; an air outlet is formed in the front lower portion of the shell; side air inlets are formed in the side faces of the shell; heat exchangers corresponding to the side air inlets are formed inside the shell; a rear air inlet is formed in the rear lower portion of the shell; an air supplying device is formed inside the shell; a volute and a centrifugal fan located inside the volute are formed inside the shell and above the air supplying device; the air outlet portion of the volute faces towards hot exchange air flues in the air supplying device and is provided with an annular surrounding part extending towards the air supplying device and annularly surrounding the hot exchange air flues; mixed air cavities are formed between the annular surrounding part and the hot exchange air flues; a diversion assembly used for adjusting the air outlet angle of the air outlet portion is formed between the air outlet portion of the volute and the air supplying device. By the application of the wall-mounted type air conditioner indoor unit, adjustment of the air supplying angle of the wall-mounted type indoor unit used for supplying soft mixed air with the proper temperature can be achieved.

Description

Technical field [0001] The present invention belongs to the technical field of air conditioning. Specifically, it relates to an indoor unit of an air conditioner, and more specifically, to an indoor unit of a wall-mounted air conditioner. Background technique [0002] The indoor units of existing wall-mounted air conditioners are all elongated, and the indoor unit is provided with a elongated air outlet. The heat exchanged by the heat exchanger is directly blown out from the air outlet under the action of the internal cross-flow fan. The wind is all heat exchange wind. Generally, no additional air supply device is provided between the heat exchanger and the air outlet. One disadvantage of this kind of air conditioner is that all the air sent out is heat exchange air, the air volume is small, and the indoor air circulation speed is slow; the other disadvantage is that the air sent out is not soft enough, especially in the cooling mode, the cool air is blown out. The wind blows d...

Problems solved by technology

However, limited by the space of the indoor unit, in this type of indoor unit, the volute where the centrifugal fan is located is very close to the air supply device, and the wind blown from the volute has a high velocity. Under the premise of satisfying the pressure loss, the volume of the volute outlet The wind divergence angle is small, and most of them blow directly to the air supply device along the direction of the volute exit, so that the air volume near the volute exit in the air supply device is large, and the air volume in other positions is small. The air supply of the air supply device is not uniform enough, which is not conducive to There is enough negative pressure in the air to introduce non-heat exchange air, and the air outlet angle of the air supply device cannot be adjusted, so the air supply has a large limitation
