Description

An apparatus for circulating the air in window type air conditioner

The present invention relates to a ventilation air conditioner of the window type air conditioner, and in more detail, the control device installed to ventilate the indoor air by introducing external air during the operation of the window air conditioner is configured so as not to flow up and down, and also, It is to prevent the breakage of parts by reducing friction during operation of the device.

In addition, the present invention relates to a ventilating device for a window type air conditioner that can simplify the work process and reduce the number of parts, as well as improve product production.

A commonly used air conditioner is a device that maintains a room temperature comfortably by using latent heat of evaporation of refrigerant gas according to a refrigeration cycle of a compressor, a condenser, an expansion valve, and an evaporator.

That is, when the pressure gauge compresses the refrigerant gas and raises the pressure and temperature of the refrigerant gas to the saturation pressure, the condenser absorbs the heat of the refrigerant gas of high temperature and high pressure by using water or air to condense the refrigerant gas. Liquefy. The refrigerant gas condensed and liquefied as described above is lowered in temperature and pressure due to the interlocking action of the expansion valve, and the refrigerant gas is evaporated in the evaporator to heat exchange the indoor air to keep the indoor temperature comfortable.

Figure 4 is a perspective view showing a general window type air conditioner operating as described above, the front cover 110 of the air conditioner 100 is formed with a suction port 111 for sucking the indoor air, one side of the heat exchanged cold air into the room A discharge port 112 for discharging is formed, and a plurality of adjustment knobs 117 for controlling the driving of the air conditioner 100 are mounted below the discharge port 112.

On the other hand, the bay plate 121 of the air conditioner main body 120 is provided with interior and exterior barrier walls 122a and 122b that separate the interior and exterior sides, as shown in FIG. In the center is a drive motor 123 for transmitting the rotational force in both directions.

Both ends of the driving motor 123 are coupled to a blowing fan 124 for circulating air and a cooling fan 125 for cooling the condenser 126 mounted on the rear surface of the outdoor side, and the blowing fan 124. While the scroll unit 130 is formed around the air conditioner body 120, an evaporator 127 is installed on the front surface of the air conditioner body 120 to heat-exchange the indoor air sucked through the inlet 111, by the evaporator 127. The heat-exchanged cold air is blown into the room through the air blower 131 formed on one side of the scroll unit 130 according to the driving of the blower fan 124. In addition, a compressor 128 for compressing the refrigerant gas at high temperature and high pressure is mounted on the outdoor side.

Therefore, when the user drives the air conditioner 100 through the adjustment knob 117 mounted on the front cover, the blower fan 124 is driven to suck the indoor air through the inlet 111. Heat exchange in the evaporator 127 according to the freezing cycle is blown into the room through the discharge port (112).

Meanwhile, a ventilation hole 132 is formed in the scroll unit 130 to ventilate the interior by introducing external air, and a ventilation path 131 formed in the scroll unit 130 to open and close the ventilation hole 132. ), The adjusting device 140 is installed. The adjusting device 140 is a long side of the rotary table 141 is formed, the control knob 142 and the opening and closing portion 143 is formed at both ends of the rotary table 141 vent hole 132 of the scroll unit 130 It is possible to control the external air flowing into.

Figure 6 is a schematic side cross-sectional view showing a state in which the conventional adjusting device is coupled, the front and rear of the adjusting device 140, the rotating handle 141 is formed with the adjustment handle 142 and the opening and closing portion 143 is formed The lower center of the swivel 141 has a hinge shaft 144 and an O-ring coupling groove 144a formed below the hinge shaft 144 to be inserted into the insertion hole 131a formed in the air passage 131. Washer 150 and the O-ring 160 is to be combined.

However, the adjusting device 140 installed as described above is directly coupled to the hinge shaft 144 of the adjusting device 140 to the insertion hole 131a formed in the air passage 131, so that the user adjusts the adjusting device 140. When rotated to the left and right to flow up and down and at the same time had a problem that the parts are damaged due to the friction of the insertion hole (131a) and the hinge shaft (144).

In addition, due to the washer 150 and the O-ring 160 coupled to the lower portion of the hinge shaft 144, a separate part enters the material cost, and as a result, the number of assembly operations increases, thereby lowering productivity.

Accordingly, the present invention has been made to solve the above problems, the control device installed to ventilate the indoor air by introducing external air during the operation of the window air conditioner is configured to not flow up and down without damage to the parts and At the same time, the purpose is to improve the productivity by reducing the number of parts, as well as reducing the number of assembly operations.

In order to achieve the above object, the present invention is provided on the bottom surface of the air passage to adjust the handle portion and the opening and closing portion is formed on the other side, the hinge is formed below the rotating shaft is installed so that the outdoor air can be introduced into the indoor side In the ventilating device of the air conditioner of the window type air conditioner, the inner peripheral surface corresponds to the outer peripheral surface of the hinge shaft between the hinge shaft of the rotating body and the insertion hole of the ventilation path, the outer peripheral edge corresponds to the inner peripheral surface of the insertion hole, Characterized in that the bushing formed with a support piece that can support the lower portion is configured
