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 exchanger, an air injection part and an air supply assembly; top wall air inlets and side wall air inlets are formed in a cover shell of the shell, and a long circular air supply opening is formed in a front panel; the heat exchanger comprises a first heat exchange section and a second heat exchange section, wherein the first heat exchange section is arranged at the position close to the front panel, and the second heat exchange section is arranged at the position tightly close to the top wall of the cover shell; an annular inner wall of the air injection part defines an air suction hole, air supply cavities are cooperatively defined by an annular outerwall and the annular inner wall of the air injection part, and the edges of the portions where the annular outer wall and the annular inner wall are connected form air injection openings which are used for spraying out the airflow in the air supply cavities forwards, so that air at the rear part of the air supply opening is sucked to pass through the air suction hole; and the air supply assembly comprises a centrifugal fan and an air guide part, the centrifugal fan is configured to enable ambient air to be fed from the top wall air inlets and / or the side wall air inlets to exchange heat with the heat exchanger, and the airflow subjected to the heat exchange is discharged to the air supply cavities through the air guide part. According to the scheme, the wall-mounted air conditioner indoorunit is compact in structure, the supplied air is soft, and the comfort level is high.

Description

technical field [0001] The invention relates to an air conditioner, 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, the air supply method of traditional air conditioners is to send cold air into the room, then slowly convect with the surrounding air, and the heat exchange speed It is slower and cannot give people a feeling of rapid cooling, and direct blowing from the air outlet of the indoor unit to people will have adverse effects on the health of users, and air-conditioning diseases are prone to occur. [0003] In response to this problem, there have been indoor units with jet outlets for soft air supply in the prior art, which use smaller air outlets to drive the surrounding air to blow out, so that the air after heat exchange is mixed with the surrounding air and sent out, but the jet outlet...

Problems solved by technology

[0002] Air conditioners are one of the necessary household appliances. As users have higher and higher requirements for comfort and health, the air supply method of traditional air conditioners is to send cold air into the room, then slowly convect with the surrounding air, and the heat exchange speed It is slow and cannot give people a feeling of cooling quickly, and blowing the air outlet of the indoor unit directly to people will have adverse effects on the health of users, and air-conditioning problems are prone to occur.

[0003] In response to this problem, there have been indoor units with jet outlets for soft air supply in the prior art, which use smaller air outlets to drive the surrounding air to blow out, so that the air after heat exchange is mixed with the surrounding air and sent out, but the jet outlets Higher requirements on the structure make the jet outlets mostly used in cabinet-type indoor units with ample space

In order to meet the structural requirements of the jet outlet, the hanging indoor unit using the jet outlet often needs to set the casing into a circular or other irregular shape. There is a gap in cognition, and it is not easy to be accepted by users; on the other hand, it also brings troubles to the installation of the hanging indoor unit, so the hanging indoor unit using the jet air outlet cannot meet the user's requirements
