Wall-mounted type air-conditioner indoor unit

Abstract

The invention provides a wall-mounted type air-conditioner indoor unit which comprises a shell, an evaporator, a fan and drainage portions. The drainage portions are arranged on the two sides of eachwind supply opening, so that the adjacent wind supply openings are spaced. Each drainage portion comprises a first induced draft groove and a second induced draft groove. The first induced draft grooves allow indoor air of the rear side of the shell to flow toward the wind supply openings through the first induced draft grooves, and the indoor air is mixed with heat exchange wind to form mixed flow wind to be blown into a room again. The second induced draft grooves allow the indoor air of the rear of the shell to flow toward the wind supply openings through the second induced draft grooves, and the indoor air is mixed with the heat exchange wind to form mixed flow wind to be blown into the room again. The first induced draft grooves, the second induced draft grooves and third induced draft grooves communicate mutually. The first induced draft grooves and the second induced draft grooves form a U-shaped full-enclosure type full drainage opening together, the area of induced draft and wind mixing is increased, wind mixing is more uniform, and the drainage amount is larger.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a wall-mounted air conditioner indoor unit. Background technique [0002] With the popularization of air conditioners, users have higher and higher requirements for the comfort and health of air supply. The traditional air conditioner has strong air supply, and the cold wind blows directly to people. Air conditioner disease is the biggest problem for users to use air conditioners. Through the continuous innovation of air conditioner technology, jet technology and drainage technology have emerged, bringing the concept of healthy air supply that is cool but not cold. However, the existing technology still has certain limitations, such as small air volume, single mixed air direction, and uneven air mixing, resulting in poor user experience when using the air conditioner’s cool but not cold health function, and cannot achieve cool but not cold Air supply effect.

Problems solved by technology

The traditional air conditioner has strong air supply, and the cold wind blows directly to people. Air conditioner disease is the biggest problem for users to use air conditioners. Through the continuous innovation of air conditioner technology, jet technology and drainage technology have emerged, bringing the concept of healthy air supply that is cool but not cold. However, the existing technology still has certain limitations, such as small air volume, single mixed air direction, and uneven air mixing, resulting in poor user experience when using the air conditioner’s cool but not cold health function, and cannot achieve cool but not cold Air supply effect

[0003] The air drainage scheme in the prior art has a small amount of induced air, and the air is induced outside the tuyere, with a single direction of the air induced, poor uniformity of air mixing, and poor user experience.
