Problems solved by technology

[0008]However, according to the above-mentioned conventional air conditioner, due to the huge heat generated by the triac element, the electrical equipment installed in the air conditioner will be heated
This has become a problem that compromises the safety of air conditioners
In addition, a fan for cooling the triac element is installed, which increases the energy consumption and cost of the air conditioner, which also becomes a problem

Abstract

An air conditioner includes: an air passage 23 that is formed in a cabinet 20 so as to connect a suction port 21 and a blowoff port 22 to each other, which are open on a surface of the cabinet 20; a blower fan 25 that is disposed inside the air passage 23 so as to extend in one direction; a heat exchanger 27 that is disposed so as to be opposed to the suction port 21 and cools air flowing in through the suction port 21; a heater 28a that is disposed between the blower fan 25 and the heat exchanger 27 in order to heat air flowing in through the suction port 21 and is shorter in a longitudinal direction than the blower fan 25; a control element 52 that controls the heater 28a and is disposed outside the air passage 23 adjacently to the air passage 23; and a heat sink 70 that is in close contact with the control element 52 and is disposed between the blower fan 25 and the heat exchanger 27, on an outside of the heater 28a in the longitudinal direction. The energy consumption and cost are reduced and the safety is increased.

Description

technical field [0001] The invention relates to an air conditioner comprising a heater and a control element which controls the heater. Background technique [0002] A conventional air conditioner is disclosed in the patent document JP-A-H8-152179. Such an air conditioner is configured as an integrated type in which an indoor unit placed indoors is installed at the front of the air conditioner, and an outdoor unit placed outdoors is installed at the rear of the air conditioner. In the outdoor unit, a compressor that performs a refrigeration cycle is provided. At the rear surface of the outdoor unit, an outdoor heat exchanger connected to the compressor is provided, and an outdoor fan for cooling the outdoor heat exchanger is provided facing the outdoor heat exchanger. [0003] A suction port is opened on the front surface of the indoor unit, and a blowout port is opened at a position above the suction port. In the indoor unit, an air duct is formed which is composed of an...
