Turbocharger housing structure of cabinet air conditioner

Abstract

The present invention provides an indoor unit turbine housing structure of cabinet air conditioner. The indoor unit turbine housing structure of cabinet air conditioner comprises a turbine housing body connected with a back cover plate, wherein, a turbine tongue, a spiral curve, a field angle, a fan, as well as a gap between the fan and the turbine tongue are arranged on the turbine housing body. The improvement of the present invention lies in that an outlet of the turbine housing body is alternately provided with flow guiding blades, which improves the airflow channel at the outlet of the turbine housing body, makes the airflow channel at the outlet part more optimized, ensures the uniform and smooth outlet air of airflow, can effectively reduce the vortex flow appearing at the turbine housing outlet part, and is advantageous to the cool-heat exchange of airflow at the part of a heat exchanger. Meanwhile, the present invention decreases noise, improves the working performance of air conditioners, and meet the environmental protection requirements.

Description

1. Technical field [0001] The invention relates to an external structure of an indoor unit of a cabinet type air conditioner, in particular to a volute structure of the indoor unit of a cabinet type air conditioner. 2. Background technology [0002] An air conditioner is a device that can keep indoor air in the most comfortable state according to different purposes. When the indoor temperature is high in summer, it can discharge low-temperature cold air into the room to reduce the indoor temperature. The hot air with higher temperature can be discharged into the room to increase the indoor temperature. The working principle of the air conditioner is to exchange the heat between the refrigerant circulating through the compressor, the condenser, the expansion device and the heat exchanger with the air passing through the heat exchanger, and then adjust the air in the indoor space for cooling and heating. [0003] The structure of the air conditioner includes an outdoor unit c...

AI Technical Summary

Problems solved by technology

[0006] Referring to Fig. 1 and Fig. 2, the volute structure of the indoor unit of the existing cabinet type air conditioner is provided with a volute tongue 11, a spiral thread 12, an opening angle 13, a gap 14 between the fan and the volute, and a fan 16. Located inside the volute; the volute 1 is fixed to the rear cover of the cabinet air conditioner, and an air flow field is formed between the outlet of the volute 1 and the heat exchanger; since the outlet of the volute 1 has only a narrow channel, so that the airflow at the outlet is not smooth and uneven, and it is easy to generate eddy current at the outlet A of the volute case 1, which reduces the working performance of the air conditioner and increases the amount of noise, so that the noise increases after the air conditioner is turned on, affecting The use effect does not meet the requirements of environmental protection
