The present invention relates to an air conditioner, and more particularly, to an air conditioner provided with a ventilation device inside the main body to ventilate the room using outdoor air.

In general, an air conditioner is a device for cooling or heating the surroundings by using an endothermic action and an exothermic action caused by vaporization or liquefaction of a refrigerant circulating in a refrigeration cycle.

Such an air conditioner is usually a separate type provided to separate the compressor and condenser of the refrigerating cycle and the indoor unit provided to be installed on the indoor side and the outdoor unit provided inside and the evaporator of the refrigeration cycle is installed on the outdoor side, the indoor unit and the outdoor unit Is divided into an integral type provided to form a body, recently, such an air conditioner is installed in the air conditioner body installed inside the air conditioner installed inside the air conditioner is used as well as indoor air-conditioning as well as indoor ventilation.

To describe the indoor unit of the separate air conditioner as an example, such an indoor unit has a main body formed with an inlet and an outlet, and the inside of the main body provides an evaporator of a refrigeration cycle and a blowing force so that the indoor air circulates through the inside of the main body. By doing so, a circulation fan for allowing indoor air to heat exchange with the evaporator, and a ventilator provided to discharge the indoor air to the outdoor side and to supply the outdoor air to the indoor side.

The ventilator is formed through a box-shaped ventilation case having one side opened and a cover provided to open and close the opening of the ventilation case, and is provided to be partitioned inside the ventilation case through partitions, respectively, inside and outside the indoor unit main body. The air supply space and the exhaust space provided to communicate with the side is formed.

In the ventilation case, a blower is provided to supply outdoor air to the inside of the main body and provides a blowing force to discharge the indoor air introduced into the main body through the inlet to the outside, and the indoor air moving along the air supply space and the exhaust space. The heat exchanger is provided to exchange heat between the outdoor air and the outdoor air. The air supply space and the exhaust space are provided to cross each other in a partitioned state so that the heat exchanger is installed.

In addition, the blower is an air supply fan for providing a blowing power so that the outdoor air is supplied to the inside of the main body through the air supply space, and provides a blowing power so that the indoor air introduced into the main body is discharged to the outdoor side through the exhaust space The exhaust fan, a pair of drive motors for driving each fan, and a first fan assembled to the air supply space side ventilation case by screwing in a state where the air supply fan and one drive motor are installed so that the air supply fan is installed in the air supply space.

First, when the circulation fan 3 inside the indoor unit main body 10 and the air supply fan 51 and the exhaust fan 52 of the ventilation device 20 are operated together, the inlet 1 flows into the main body 10 through the inlet 1. Some of the air is discharged to the outdoor side through the exhaust passage of the ventilator 20, and through the air supply passage of the ventilator 20 and the remaining part of the air introduced into the indoor unit body 10 through the inlet (1) The outdoor air delivered into the main body 10 is discharged to the indoor space through the discharge port 2 in a heat exchanged state through the evaporator 4, thereby cooling and ventilating the room simultaneously. In addition, the air conditioner according to the present invention may drive only the air supply fan 51 and the exhaust fan 52 of the ventilator 20 in a state in which the circulation fan 3 is stopped so that only the indoor ventilation is performed. have.

In addition, the air conditioner according to the present invention the fitting groove (55a) of the pan support plate 55 in a state in which each of the components of the blower device 50, except for the pan support plate 55 is coupled to the pan support plate 55 The fan support plate 55 is simply inserted into the ventilation case 21 in which the cover 22 is opened so as to be coupled to the partition 29 of the ventilation case 21. Since it can be easily assembled, the blower 50 can be easily assembled inside the narrow ventilation case 21.

In addition, when the blower 50 is separated from the ventilator 20 installed inside the main body 10 for maintenance of the blower 50, the opening / closing door 6 at the rear of the main body 10 is opened. And the fan support plate 55 is pulled to the upper side of the open ventilation case 21 in a state in which the cover 22 is opened to open the upper part of the ventilation case 21 and the fan together with the pan support plate 55. The remaining components of the blower 50 coupled to the support plate 55 are drawn out of the ventilation case 21 and the blower 50 is simply separated from the ventilator 20, so that the blower 50 is disassembled. Work can also be done simply.

As described in detail above, the air conditioner according to the present invention includes a fan support plate provided with a blower installed in the main body ventilator, the air supply fan and the exhaust fan and the pair of fans are installed together. Since the plate is provided to be detachably attached to the partition of the ventilation case by a simple fitting method, it is advantageous to facilitate the disassembly and assembly of the blower installed in the ventilation device even if the space inside the ventilation case is somewhat narrow.
