Rear cover plate structure of indoor machine for cabinet air conditioner

Abstract

The invention provides a rear cover plate structure of cabinet air conditioner indoor unit , comprising a plate body. The invention is characterized in that: an inner arc part of a body stamping is straightly connected with the upper part of the rear cover plate body; the width of the inner arc part is less than the width of the heat exchanger, the length of the inner arc part is 800 to 1000 mm, the distance between the top of the inner arc part and the installation position of the heat exchanger upper part is 50 to 100 mm, the arc radius of the inner arc part is 350 to 360 mm, the central angle is Pi / 18-Pi / 6 degrees, the depth of the inner arc part is 100 to 500 mm. The invention has the advantages of increasing the rear cover plate intensity, optimizing the airflow passage of the casing, reducing noises effectively, making airflow outlet uniformly and properly, improving the working performance of the air conditioner, and meeting the environmental protection.

Description

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

AI Technical Summary

Problems solved by technology

[0007] refer to figure 1 As shown, the rear cover plate 1 of the indoor unit of the existing cabinet-type air conditioner is a vertical flat plate with low strength. The airflow formed inside the shell is allowed to flow out due to the small gap, which will easily lead to unsmooth and uneven airflow, and eddy current A will easily be generated at the top of the shell, which will affect the performance of the air conditioner. performance, and noise occurs

In addition, due to the low strength of the rear cover 1, the motor will drive the rear cover 1 to vibrate when it is working, which will further increase the noise intensity. Generally, the noise of the air conditioner will reach 100HZ after the air conditioner is turned on, which affects the use effect and does not meet the requirements of environmental protection.
