Air conditioner

Abstract

An air conditioner contains a ventilating device, which drives an exhaust fan and a suction fan at the same time by means of the same electrical motor to complete synchronous air exhaust and air suction, inside the side space of a heat exchanger arranged inside the indoor unit of the air conditioner; moreover, the air conditioner does not complete air exhaust or air suction only. In addition, because both the left side and the right side of the electrical motor are provided with the fans to form a long ventilating device in transverse direction, the indoor unit needs to be improved to a transversely long type. The invention provides a thin ventilation unit which can select the operation of air supply and air exhaust and can be contained inside the narrow space positioned at one side of the heat exchanger arranged inside the air conditioner; moreover, the ventilation unit has an air supply / exhaust fan rotating in a single direction and capable of selecting air supply mode and air exhaust mode; an air passage in air supply mode and air exhaust mode is formed through switching the air passage by a switch valve; therefore, a thin-type passage structure is realized, and the ventilation unit which is suitable to be contained inside the narrow space positioned at one side of the heat exchanger is formed.

Description

technical field [0001] The present invention relates to an air conditioner equipped with a ventilator, and more particularly to an air conditioner equipped with a ventilating unit in which an air passage is switched by operating a switching valve during air supply and exhaust operations. Background technique [0002] A ventilator that simultaneously drives an exhaust fan and an intake fan by the same motor to perform exhaust and intake air is housed in a side space of a heat exchanger housed in an indoor unit of an air conditioner (for example, refer to Patent Document 1). [0003] Patent Document 1: JP-A-2002-005472 [0004] In Patent Document 1, since the exhaust fan and the intake fan are simultaneously driven by the same motor, although it functions as a ventilator that performs exhaust and intake at the same time, it cannot be configured to perform only exhaust or only intake. In addition, since the Sirocco fans are installed on the left and right sides of the motor, a...

Problems solved by technology

[0004] In Patent Document 1, since the exhaust fan and the suction fan are simultaneously driven by the same motor, although it functions as a ventilator that performs exhaust and suction at the same time, it cannot be configured to perform only exhaust or only suction.

In addition, since the Sirocco fans are installed on the left and right sides of the motor, and the exhaust hose and the suction hose are installed on each fan case, the ventilator with a long form in the left and right direction is formed. The indoor unit of the air conditioner must be improved to a horizontally long type that is relatively long horizontally
