The present invention relates to a floor takeout apparatus used in a floor air conditioning system, and more particularly, to a floor takeout apparatus used in a floor air conditioning system, So as to provide a more comfortable use environment.

Generally, the air conditioner is a device used to provide a comfortable environment for people to live or to preserve the equipment by allowing the temperature of the room to be maintained at a predetermined temperature. It is widely used in various places such as the field.

Conventionally, most of the air conditioners are composed of a ceiling air conditioning system, and the air conditioner of the ceiling air conditioner maintains the indoor temperature at a certain level by supplying cool air or warm air through the ceiling of the indoor space .

In the case of the above-mentioned ceiling air-conditioning system, in order for the cool air from the ceiling to fall down to a height of 1.8 m or less in which people are mainly active, the upper air of the indoor space must first be cooled down and then cooled down. The disadvantage is that installation and maintenance are not easy since the air extraction unit and the duct must be installed on the ceiling, and sufficient space is required in the upper part of the ceiling, so that space utilization of the building is lowered.

In consideration of such disadvantages, an air conditioner of a floor take-out type (hereinafter referred to as a floor air conditioning system) has been proposed and used.

Fig. 1 shows a structural diagram of a floor air conditioning system.

In the floor take-out apparatus, the air conditioning air supplied from the air conditioner not shown to the lower portion of the access floor flows into the air conditioning air inlet, and the air conditioning air introduced into the air conditioning air inlet is supplied to the room through the outlet by the operation of the fan.

Meanwhile, the damper closes the indoor air inlet at the time of initial cooling or heating, and opens the air-conditioning air inlet port so that a large amount of air-conditioning air can be supplied to the room, thereby inducing the actual indoor temperature to reach the set temperature as soon as possible .

On the other hand, when the actual temperature of the room reaches the set temperature, the damper opens and closes the air-conditioning air inlet and the room air inlet according to the change of the room temperature and adjusts the amount of the air- Level.

In such a conventional floor take-out apparatus, the air conditioning air inlet and the indoor air inlet are opened or closed by a damper, that is, 100% open or 100% close is repeatedly performed. There is a problem that noise is generated in the process of opening and closing the inlet.

Further, when the room temperature reaches the set temperature, the air-conditioning air inlet is closed by the damper, thereby blocking the inflow of fresh air-conditioned air. If such a state is maintained for a long time, .

In addition, foreign matter such as dust existing on the floor of the access floor flows into the air-conditioning air inlet port together with the air-conditioning air, and when such foreign matter is introduced into the room through the outlet port, There is a problem in that it is adhered to a component installed inside the case and contaminates the floor take-out apparatus.
