Wall-mounted air conditioner indoor unit

Abstract

The invention provides a wall-mounted air conditioner indoor unit. The wall-mounted air conditioner indoor unit comprises a shell, an air supply device, a heat exchange device, an air injection part and a fresh air device; a first air inlet is formed in the top of a case of the shell; a first air supply outlet is formed in the lower portion of a front panel; the air supply device promotes air to be sent out from the first air inlet through the first air supply outlet; the heat exchange device is arranged between the first air inlet and the air supply device so as to perform heat exchange withthe air entering the shell from the first air inlet; the air injection part is arranged below the first air supply outlet; an air injection port is formed in the edge, connected to an annular inner wall, of an annular outer wall; the fresh air device is arranged on one side of the shell and is provided with a fresh air pipe and a fresh air fan, wherein the fresh air pipe communicates with a freshair source environment; the fresh air fan enables fresh air flow to be sprayed out forwards from the air injection port so as to drive ambient air to mix with the air which is sent out by the first air supply port and is subjected to heat exchange in front of the shell. According to the scheme of the wall-mounted air conditioner indoor unit, the air supply distance can be increased, the user experience can be improved, and the air quality can be improved.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to an indoor unit of a wall-mounted air conditioner. Background technique [0002] Air conditioners are one of the necessary household appliances. As users have higher and higher requirements for comfort and health, traditional air conditioners generally need to be used in a closed environment. When used for a long time, the freshness of the air will decrease, which will make users Feeling suffocated. In response to this problem, a fresh air system has occurred in the prior art. The working principle of the fresh air system is to use the fresh fan to purify the outdoor air and introduce it into the room. The equipment of the fresh air system is complicated, the cost is high, and it needs to occupy a large space. [0003] In addition, the air supply method of the existing air conditioner is to send the cold air into the room, then slowly convect with the surrounding air, and...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, there is a scheme of increasing airflow drainage in the indoor unit of the wall-mounted air conditioner in the prior art. The main reason is that the airflow at the air outlet drives the airflow out of the drainage outlet. Although the mixed effect of cold and hot air can be achieved, the amount of airflow is relatively small. , the mixing effect is not too obvious, the effect is not ideal
