Indoor unit of air conditioner and airflow control method thereof

Abstract

The invention provides an indoor unit of an air conditioner and an airflow control method thereof. The indoor unit of the air conditioner and the airflow control method thereof can solve the problems that the circulation and convection effect between air output by air conditioners and indoor air is poor in the refrigeration process of indoor units, balance of the indoor temperature is difficult and the comfort level is low in the prior art. The indoor unit of the air conditioner comprises a shell, a framework, an evaporator, a fan, an air outlet and an air guide plate, an air suction port is formed in the bottom side surface of the framework, an air suction channel is formed in the back of the framework, an air inlet is formed in the top of the shell, a top panel used for opening or closing the air inlet is arranged on the top of the shell, and a first drive part used for driving the top panel to open or close the air inlet is installed in the shell. According to the indoor unit of the air conditioner and the airflow control method thereof, flowing circulation can be formed between the air output by the air conditioner and the indoor air both in the refrigeration process and the heating process, the air output by the air conditioner and the indoor air can be fully mixed, and the comfort level can be increased; in the refrigeration process, the top panel closes the air inlet, indoor hot air enters the air conditioner from the air suction port in the lower part for participating in heat exchange, top hot air close to the roof does not participate in heat exchange, and therefore the energy conservation effect is greatly improved, and the energy consumption is lowered.

Description

technical field [0001] The invention relates to a wall-mounted air conditioner indoor unit and an air flow control method thereof. Background technique [0002] In the prior art, the air inlet and outlet structure of the indoor unit of the wall-mounted air conditioner is that the air enters from the upper part and the air comes out from the lower part. Specifically, an air intake grill is arranged on the top panel of the indoor unit housing to form an air inlet, and an air deflector is arranged on the bottom panel of the housing to form an air outlet. [0003] When cooling, the air deflector blows the cold air flatly, and then the cold air forms natural convection and sinks due to its high density to adjust the comfort. When heating, the air deflector blows the hot air downward, and then the hot air, due to its low density, forms natural convection and floats up to adjust the comfort. As we all know, the air from the indoor unit does not blow directly on the human body and...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides an air-conditioning indoor unit and its airflow control method, which can solve the problem of slow circulation convection between air-conditioning air outlet and indoor air when the indoor unit is in cooling operation in the prior art, and it takes a long time for the indoor temperature to reach a balance, resulting in poor comfort experience. The problem is not good. During cooling and heating, the air from the air conditioner and the indoor air can form a flowing cycle and fully mix, so that the indoor temperature can be quickly balanced and the comfort level can be improved.
