Description

A method for adjusting the direction of the wind discharged from an air-conditioner

The present invention relates to a wind direction adjustment method of the air conditioner, and more particularly, to a wind direction adjustment method of the air conditioner for the user's convenience by adjusting the blade for varying the discharge direction of the cold air heat exchanged in the evaporator at a desired angle within a short time.

In general, an air conditioner is a device that comfortably maintains a room temperature 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 compressor 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 and liquefy the refrigerant gas. . The refrigerant gas condensed and liquefied in this way has a low temperature and pressure due to the throttling action of the expansion valve, and the refrigerant gas evaporates in the evaporator to heat-exchange the indoor air to keep the indoor temperature comfortable.

Meanwhile, a blower fan 230 is installed at the inner center of the air conditioner main body 200 to suck the indoor air through the suction port 210 and blow air cooled in the evaporator 250 to the room through the discharge port 220. The front of the main body 200, the operation panel 240 is installed so that the user can control the air conditioner.

Therefore, when the user drives the air conditioner through the operation panel 240, the blowing fan 230 mounted inside the main body 200 is driven to suck the indoor air through the suction port 210. At this time, the sucked indoor air Heat exchange in the evaporator 250 is blown into the room through the discharge port 220.

On the other hand, the discharge direction of the cold air blown into the room is changed by the rotation of the blade 221 mounted to the discharge port 220. That is, as shown in FIG. 4, when the user turns on the wind direction selection button of the operation panel 240 while the air conditioner is being driven, the stepping motor (not shown) for rotating the blade 221 performs forward / reverse rotation at a predetermined cycle. It is repeatedly performed to change the discharge direction of cold air (301 to 303).

In other words, the stepping motor rotates in a constant direction, for example, forward rotation, reverse rotation, and forward rotation according to the operation of the wind direction selection button, and the blade linked to the stepping motor rotates according to the forward and reverse rotation of the stepping motor. The discharge direction of cold air is varied. In such a state, in order to fix the discharge direction of the cold air in a predetermined direction, the user must stop the driving of the stepping motor by turning on the wind direction selection button again (304 to 305).

However, when the rotating blade stops outside the desired position, the user must turn on the wind direction adjustment button again to rotate the blade, wherein the stepping motor rotates in the order of forward rotation, reverse rotation, and forward rotation as described above. As a result, the user was inconvenient to wait for the blade to reach the desired position.

Accordingly, the present invention has been invented to solve the above problems, and provides a wind direction adjustment method of the air conditioner that can adjust the blade at a desired angle within a short time by the user directly controls the rotation direction of the stepping motor for rotating the blade of the air conditioner It is for that purpose.

In order to achieve the above object, the present invention provides a method for adjusting the air conditioner of the air conditioner. After the user drives the air conditioner, the user turns on the air direction selection button to rotate the stepping motor forward and reverse to change the discharge direction of the cold air and to step. A first step of setting or resetting the flag register according to the rotational direction of the motor; and if the user turns on the wind direction selection button again for a predetermined time in the first step, whether the stepping motor rotates forward or backward through the flag register; A second step of judging; a third step of reversely rotating the stepping motor and resetting the flag register if the stepping motor is in forward rotation in the second step; and a stepping motor if the stepping motor is in reverse rotation in the second step. Rotate the motor forward and set the flag register, and after performing the third to fourth steps, Claim characterized in that the repeat step 2.
