Description

A switchgear for sucking in air-conditioner

The present invention relates to an air conditioner, and more particularly, to an opening and closing device of an intake port, which is a passage for sucking indoor air into a body for heat exchange.

In general, an air conditioner is referred to as an "air conditioner," which is a cooling device that lowers a room temperature to a temperature below a certain temperature by inhaling hot air in a room and cooling and discharging it by a heat exchange action by a heat exchanger.

The air conditioner is classified into a type of tooth type, a wall type, a window type and the like according to the installation place and location.

The upper tooth type is installed on the floor of the room, the wall type is attached to the wall of the room, and the window type is attached to the window.

At this time, although the indoor unit and the outdoor unit are separated from each other, the window type is an indoor unit and an outdoor unit.

Looking at the structure of a conventional general air conditioner with reference to the accompanying Figures 1 and 2 as follows.

1 is a perspective view showing a general air conditioner and FIG. 2 is a longitudinal sectional view of FIG. 1, wherein the air conditioner includes a blower fan 3 generating a suction force while rotating according to the driving of the motor 2 installed in the main body 1; It is formed in the lower portion of the main body as the suction fan is generated by the rotation of the blowing fan (3) and the inlet port (4) to be introduced into the interior of the main body, and inclined in the main body is introduced into the main body A heat exchanger (5) for converting hot air into cold air by an evaporation action, a discharge port (6) formed at an upper portion of the main body to allow the air cooled by the evaporation action of the heat exchanger to escape to the room; The condensate receiver 7 installed at the lower part of the heat exchanger to collect the condensate generated by the heat exchange action and fixed to one side of the condensate receiver are collected outside the main body. And a drain hose 8 discharged to the negative portion.

In the air conditioner configured as described above, when power is applied while the cooling operation mode is set, the blower fan 3 installed inside the main body 1 rotates to generate suction power. Flows into the interior.

As described above, when the hot air in the room is introduced into the main body 1 by the driving of the blower fan, the refrigerant compressed and condensed in the compressor of the outdoor unit (not shown) flows into the heat exchanger 5 side through a pipe. do.

Accordingly, the hot air introduced into the main body 1 is cooled by the evaporation action of the heat exchanger 5, and then moves to the upper side of the main body 1, that is, the discharge port 6, and is discharged into the room. Gradually falls.
