Wall-mounted air conditioner and cabinet air conditioner with image display function

Abstract

The invention discloses a wall-mounted air conditioner and a cabinet air conditioner which can make images on a display panel not limited by the installation positions of light-emitting diode (LED) lamps any more, save space and reduce the using number of the LED lamps. The wall-mounted air conditioner and the cabinet air conditioner comprise display units, air-conditioning units and shells, wherein the display units comprise display panels and LED projection devices; the air-conditioning units are combined with the display units and comprise heat exchangers and fans to refrigerate, heat or purify air; and the display units and the air-conditioning units are arranged in the shells, and the shells comprise air inlets and air outlets; and the LED projection devices comprise motors, and a plurality of LED lamps are arranged on motor shafts. By utilizing the wall-mounted air conditioner and the cabinet air conditioner with the structure, a large-area animation projection display function can be realized, power consumption is low, heat quality is low, and radiating performance is high.

Description

technical field [0001] The invention relates to an air-conditioning indoor unit, in particular to a wall-mounted air conditioner and a cabinet-type air conditioner with image display functions. Background technique [0002] Generally, an air conditioner is arranged in any indoor space or wall of an office or a home, and serves as a device for heating or cooling room air. An air conditioner includes a compressor, a condenser, an expansion valve, and an evaporator, thus forming a refrigeration cycle. In this case, the compressor, condenser, expansion valve and evaporator are coupled sequentially. [0003] Specifically, the air conditioner includes an outdoor unit arranged outdoors (ie, the outdoor or heat radiation end) and an indoor unit arranged indoors (ie, the indoor or heat absorption end). The outdoor unit includes a condenser (ie, an outdoor heat exchanger) and a compressor. The indoor unit includes an evaporator (ie, an indoor heat exchanger). [0004] As is known ...

AI Technical Summary

Problems solved by technology

CRT is bulky, heavy, and takes up space, and has gradually faded out of the application field of air-conditioning indoor unit display. LCD has the disadvantages of being expensive, fragile, and short in life, which brings a lot of inconvenience to users and manufacturers during the application process.

In recent years, most of the LED display screens have been used in the market. LED display screens have the advantages of reliability, high efficiency, energy saving, bright, can be spliced ​​arbitrarily, and are technically the most convenient to implement. However, LEDs are driven by low-voltage DC. , the additional rectification and step-down circuit consumes most of the power and generates a lot of heat

At the same time, LED lights are fixed on the PCB circuit board. To achieve large-area display, the area of ​​the PCB circuit board and the number of LED lights must be increased, which increases the cost, takes up a lot of space, and affects the air volume.
