Air conditioner indoor unit

Abstract

The invention relates to an air conditioner indoor unit. The air conditioner indoor unit comprises an annular machine case, a first heat exchanger, a second heat exchanger, a first air flow driving device and a second air flow driving device. The axis of the annular machine case extends in the front-back direction. The annular machine case is provided with an air inlet grille located on the rear side of the annular machine case and distributed in the circumferential direction of the annular machine case and an annual air outlet located on the front side of the annular machine case and distributed in the circumferential direction of the annular machine case. The first heat exchanger and the second heat exchanger are independently arranged in the annular machine case correspondingly and areconfigured to be controlled to conduct heat exchange with air flow flowing through the first heat exchanger and the second heat exchanger correspondingly; the first air flow driving device is configured to be controlled to enable part of air flow going into the annular machine case through the air inlet grille to be subjected to heat exchange in the first heat exchanger and then flow to the annular air outlet in a refrigerating mode; the second air flow driving device is arranged in the annular machine case, located below the first air flow driving device and configured to be controlled to enable part of air flow going into the annular machine case through the air inlet grille to be subjected to heat exchange in the second heat exchanger and then flow to the annular air outlet in a heatingmode. The air conditioner indoor unit is wide in air supply scope, attractive in appearance and good in refrigerating and heating experience.

Description

technical field [0001] The invention relates to air-conditioning technology, in particular to an air-conditioning indoor unit. Background technique [0002] At present, there are two types of traditional air-conditioning indoor units: vertical and wall-mounted. The indoor units of the existing wall-mounted air conditioners are all strip-shaped, which use a bent evaporator for heat exchange, and use fan-type drive components such as cross-flow fans, axial fans, or centrifugal fans to supply air. The air supply outlet is usually Long strip. The existing vertical air-conditioning indoor unit is a vertically placed column, which uses a plate evaporator for heat exchange, and uses fan drive components such as a cross-flow fan, an axial fan, or a centrifugal fan to supply air, and the air supply port is rectangular. These existing air-conditioning indoor units are not only prone to appearance visual aesthetic fatigue, but also the air supply range of the air supply port is relat...

AI Technical Summary

Problems solved by technology

These existing air-conditioning indoor units are not only prone to appearance visual fatigue, but also the air supply range of the air supply port is relatively small

[0003] Moreover, traditional air-conditioning indoor units generally have the problem of cold air flowing downward and hot air ascending, which affects the user experience, especially for desktop air-conditioning indoor units placed on the table, which have higher requirements on appearance, and because the distance from the user is relatively large. Recently, the uncomfortable experience of sinking cold wind and rising hot wind has become more prominent
