Abstract

An indoor unit of air conditioner has an external upper panel, a partition under said external upper panel, a control box containing a built-in circuit board fixed to said partition and an electric air heater, a fan housing able to slide back and forth under said control box, and a heater contained region formed on the back of said control box. Said electric air heater can be easily installed or detached via the internal space of control box.

Description

technical field [0001] The present invention relates to an air conditioner, and more specifically relates to a heater setting area formed on the control box at the lower part of the upper panel, where the electric heater can be disassembled and accessed, and has electronic components that are conveniently installed on one side by means of circuit board installation. An indoor unit of an air conditioner composed of circuit boards. Background technique [0002] Generally, an air conditioner is installed in an office or home room or on a wall for cooling or heating, and is a machine that circulates a refrigerant by a compressor, a condenser, an expansion valve, and an evaporator. [0003] The air conditioners are respectively composed of an outdoor unit installed outdoors having a condenser or an outdoor heat exchanger and a compressor, and an indoor unit installed inside a building, the indoor unit having an evaporator. [0004] In addition, the air conditioner can be roughly...

AI Technical Summary

Problems solved by technology

[0013] Since the multiple parts arranged inside the control box (24) are fixedly connected by screws, the assembly and disassembly operations are troublesome

[0014] Moreover, in the above-mentioned structure in the past, since there is no heater for heating the air, the heating operation cannot be carried out; in addition, since the partition plate (22) and the fan cover (30) are integrally formed, it is very inconvenient for maintenance work.
