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, a heat exchange air inlet duct, a heat exchanger, a heat exchange airoutlet duct, a fan and a non-heat exchange air drainage duct; the heat exchange air inlet duct is formed in the shell and communicates with an air inlet; the heat exchanger is arranged in the heat exchange air inlet duct; the heat exchange air outlet duct communicates with the heat exchange air inlet duct; the fan is arranged in the heat exchange air outlet duct; the non-heat exchange air drainage duct is separated from the air inlet and the heat exchange air inlet duct and comprises a drainage port and a drainage air duct; and the drainage air duct communicates with the drainage port and theheat exchange air outlet duct, so that indoor air flow entering through the drainage port is directly mixed with heat exchange air at the heat exchange air outlet duct. According to the wall-mountedair conditioner indoor unit, the outgoing air is softer, cool but not cold, and the comfort degree is improved; and the non-heat exchange air drainage air duct is separated from the heat exchange airinlet air duct, so that the air rush phenomenon is avoided, and the refrigerating performance and the heating performance of the product are not influenced.

Description

Technical field [0001] The present invention belongs to the technical field of air conditioning equipment, in particular a structure of a wall-mounted air conditioning indoor unit is improved. Background technique [0002] With the promotion and popularization of air conditioning concept of health, comfort requirements of users of air conditioning is increasing. Traditional air conditioner blowing strong, cold wind blowing straight, resulting in poor user experience, the air conditioning problem sick frequently. With the development of air-conditioning technology, the emergence of drainage technology, part of the upcoming indoor air drainage to the indoor unit, which is not part of the air flow through the indoor heat exchanger, known as non-air heat exchange, and through the indoor heat exchanger after heat exchange air mixed to form a mixed air, the air blowing from the indoor unit, not resorted to cool the cold. [0003] However, there are some limitations of the prior art, it...

AI Technical Summary

Problems solved by technology

[0003] However, there are certain limitations in the existing technology. Usually, the mixed flow is realized by changing the form of the air conditioner on-hook. On the one hand, the volume of the product is increased, which brings about a significant increase in cost; some auxiliary devices are added for special air supply. Mixed flow also brings about an increase in cost, and at the same time, changes in volume and shape have an adverse effect on the standardization and unification of the back-end installation process

At the same time, in some models, both the non-heat exchange channel and the heat exchange channel are located at the air inlet, resulting in interference between the inflow paths of the non-heat exchange air and heat exchange air. Since the non-heat exchange air channel is not blocked by the heat exchanger, the pressure The loss and resistance are small, and the air flow will preferably pass through the non-heat exchange air channel, so that the air flow passing through the heat exchanger is reduced, that is, the commonly known phenomenon of non-heat exchange air channel grabbing air occurs, which seriously affects the cooling and heating performance of the product. This kind of problem cannot be effectively solved by increasing the area of ​​the air inlet area and increasing the speed, but will bring about adverse effects such as larger product size and louder noise.
