DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly, to a diffuser constituting a lower portion of an air outlet, which is rotated upward during both cooling and heating operations to reduce the opening area of the air outlet. Throttle, increase wind speed, extend range,
Cooling is cooler and heating is related to a structure that allows warmer air to flow.

2. Description of the Related Art A conventional air conditioner is, for example, shown in FIGS.
And FIG. In the drawing, 1 is an indoor unit main body of an air conditioner, 1a is a main body casing constituting the main body 1, 2 is a suction port provided on the front and top surfaces of the main body 1, and 3 is provided at a lower part of the main body 1. An outlet for sending air into the room; 4, an air passage connecting the inlet and the outlet; 5, a heat exchanger provided in the air passage; 6, a blower fan; An upper and lower wind direction plate 8 movably supported on the shaft is provided on at least one side of the air outlet 3, and a wind direction plate driving motor for driving the upper and lower wind direction plate 7; A diffuser 10 which is constructed and rotatably supported is a diffuser drive motor for driving and rotating the diffuser 9, and 11 is a group of left and right wind direction plates.

In the above configuration, during the cooling operation, the upper and lower wind direction plates 7 are rotated to a substantially horizontal position, and the upper surface of the diffuser 9 is substantially parallel to the lower surface of the casing 1a. In the heating operation, the opening area of the air outlet 3 is increased by rotating the diffuser 9 downward while rotating the upper and lower wind direction plates 7 to a substantially vertical position, thereby increasing the opening area of the air outlet 3. And have been made to improve heating capacity.

[0004] However, if the blowing area is increased during the cooling operation, the wind speed decreases, and the reaching distance is short. Furthermore, since the blowing temperature does not decrease as much as the air volume increases, it feels as though it is not cold. In addition, during the heating operation, there is also a problem that the blowout temperature does not rise and the user does not feel warm because of the increase in the air volume.

[0005]

SUMMARY OF THE INVENTION In view of the above problems, in the present invention, the diffuser forming the lower portion of the air outlet is rotated upward during both cooling and heating operations to reduce the opening area of the air outlet. , Increase wind speed, increase reach,
The purpose of the present invention is to provide an air conditioner in which cooling is cooler and heating is able to send warmer air.

[0006]

In order to solve the above-mentioned problems, a heat exchanger and a blower fan are provided in an air passage of a main body casing connecting a suction port at an upper part of the main body and an air outlet at a lower part of the main body, An upper and lower wind direction plate is rotatably supported at the outlet,
A drive motor for driving the vertical wind direction plate is provided on at least one side of the air outlet, and a diffuser constituting the air outlet is rotatably supported at a lower end portion of the air outlet, and the vertical wind direction plate is In the air conditioner, wherein the diffuser rotates downward when rotated to a substantially vertical position,
The diffuser can be rotated upward during the cooling operation in which the vertical wind direction plate is rotated to a substantially horizontal position and the heating operation in which the vertical wind direction plate is rotated to a substantially vertical position.

[0007] Further, the opening area of the air outlet during the heating operation can be made smaller than that during the cooling operation.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. 1, 2 and 3, reference numeral 1 denotes an indoor unit main body of an air conditioner, and 1 a denotes the main unit 1 of the air conditioner.
2 is a suction port provided on the front and top surfaces of the main body 1, 3 is provided at a lower portion of the main body 1, and an outlet for sending air into a room, 4 is the suction port and the outlet. 5 is a heat exchanger provided in the air passage, 6 is a blower fan, 7 is an upper and lower wind direction plate rotatably supported by the air outlet 3, and 8 is an air outlet of the air outlet 3. A wind direction plate driving motor provided on at least one side and driving the vertical wind direction plate 7, a diffuser 9 that constitutes a lower end portion of the outlet 3 and is rotatably supported by a shaft, and 10 is a diffuser 9. A drive motor for a diffuser for driving and rotating the motor, and 11 is a group of left and right wind direction plates.

The upper and lower wind direction plates 7 and the diffuser 9
The position of the diffuser 9 changes according to an operation mode such as cooling and heating, and the position of the diffuser 9 can be selected as desired. During cooling operation, when the upper and lower wind direction plates 7 are turned to a substantially horizontal position to simply lower the room temperature, the position of the diffuser 9 is changed as in the conventional case, and the upper surface of the diffuser 9 is The air flow should be substantially parallel to the lower surface.
When a person wants to take a cool wind, as shown in FIG. 2, the diffuser 9 is turned upward to set the opening area of the air outlet 3 to about 75%, so that the wind speed can be reduced. To increase the range and provide cooler, cooler air.

In the heating operation, the upper and lower wind direction plates 7 are turned to a substantially vertical position, and when it is desired to simply raise the room temperature, the position of the diffuser 9 is made to be downward as in the conventional case, and the air volume is reduced. To increase. When a person wants to take a warm wind, as shown in FIG. 3, the diffuser 9 is turned upward to reduce the opening area of the outlet 3 to about 60.
By setting to be limited to%, the temperature is increased, the wind speed is further increased, and the warm air is allowed to reach the floor, so that a warmer air is obtained.

In the above configuration, during the cooling operation, the vertical wind direction plate 7 can be turned to a substantially horizontal position and the diffuser 9 can be turned upward. During the heating operation, the vertical wind direction plate 7 can be turned substantially. By rotating the diffuser 9 upward while rotating to the vertical position, when cooling, when a person wants to take a cool wind, the wind speed is increased to extend the reach. An air conditioner that can produce a cooler, cooler air and, when heating, if a person wants to take a warmer air, raise the temperature, further increase the wind speed, and allow the warmer air to reach the floor to obtain a warmer air. Becomes

[0012]

As described above, according to the present invention, during cooling,
If a person wants to take a cool breeze, increase the wind speed, extend the reach, and get a cooler cool breeze.At the time of heating, if a person wants to take a warm breeze, raise the temperature and further increase the wind speed, An air conditioner that allows warm air to reach the floor and obtain warmer air.
