Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind direction control method for an air conditioner.

[0002]

2. Description of the Related Art Conventionally, in this type of air conditioner,
For example, as shown in Japanese Utility Model Application Laid-Open No. 2-109950, there is one vertical wind direction plate, and when the blowing temperature is low in order to prevent cold draft during heating operation, the wind direction plate is moved substantially horizontally. A method is known in which the airflow direction plate is directed downward and the temperature distribution is made uniform when the blowing temperature becomes high.

[0003]

However, since the wind direction is limited by one upper and lower wind direction plate, it takes time to make the temperature distribution in the entire room uniform. Further, it is difficult to make the temperature distribution in the entire room uniform without giving an unpleasant air flow feeling.

The present invention has been made in view of the above problems, and an object thereof is to provide a wind direction control method for an air conditioner which can quickly create a comfortable living environment without giving an unpleasant air flow feeling. Especially.

[0005]

In order to solve the above-mentioned problems, the wind direction control method of the present invention is directed to an air outlet formed on the outlet side of a blower circuit including a heat exchanger and a blower fan. It has a vertical wind direction control plate having a plate and a horizontal wind direction control plate for controlling the left and right wind directions, and the upper blade of the vertical wind direction control plate has an upper surface portion and a lower surface portion, and the lower blade has an upper surface portion and a lower surface portion. A vertical wind direction control plate drive means for independently rotating the upper and lower blades of the vertical wind direction control plate, a horizontal wind direction control plate drive means for rotating the horizontal wind direction control plate,
An air conditioner having heat exchanger temperature detecting means for detecting the temperature of the heat exchanger of the air conditioner, control means for controlling the vertical wind direction control plate driving means and the horizontal wind direction control plate driving means by the heat exchanger temperature. In the case where the heat exchanger temperature is detected during the heating operation of the air conditioner, and the heat exchanger temperature is lower than a preset temperature, the upper blade and the lower blade of the vertical airflow direction control plate are directed substantially horizontally. When the temperature of the heat exchanger becomes higher than a preset temperature, the upper blade of the vertical airflow direction control plate is directed substantially horizontally, and
The lower blades of the vertical airflow direction control plate are oriented substantially vertically.

[0006]

With the above-described structure, the present invention can quickly raise the temperature of the entire room by dividing the warm air in two directions, that is, the substantially horizontal direction and the substantially vertical direction, without giving a feeling of air flow. The temperature distribution in the entire room can be made uniform.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a cross-sectional view of a blowout part of an air conditioner according to an embodiment of the present invention. In the figure, the indoor unit 11 includes a heat exchanger temperature detecting means 13 for detecting the temperature of the heat exchanger 12, and a blower fan 15 and an outlet 16 for circulating blown air 14 in the room.
And an upper blade 17 and a lower blade 18 which control the wind direction of the flow introduced from the blowing air 14. In FIG. 2, the indoor unit 21 includes a heat exchanger temperature detecting means 22, an indoor control section (microcomputer) 23, a vertical wind direction control plate driving means 24 for driving the upper and lower blades, and a left and right wind direction for driving the left and right blades. The control plate drive means 25 is provided.

Next, the operation of the wind direction control method applied to the air conditioner having the above configuration will be described with reference to the flow chart of FIG. 3 and FIG.
The operation will be described with reference to FIG.

First, when the heating operation is started, the heat exchanger temperature t is detected by the heat exchanger temperature detecting means 22 and compared with a preset temperature T1 in the indoor control section 23. If t <T1 Control signal 1 is output from the indoor control unit 23 to the vertical wind direction control plate drive means 24, and the upper blade 17
The blown air 14 is blown out in a substantially horizontal direction by directing the lower blade 18 in a substantially horizontal direction (step 1). Also, t ≧ T
In the case of 1, the control signal 2 is output from the indoor control unit 23 to the vertical airflow direction control plate drive means 24, and the upper blade 17 is directed in a substantially horizontal direction, and the lower blade 18 is directed in a substantially vertical direction. The wind 14a is blown out substantially horizontally between the upper surface 17a of the upper blade 17 and the upper outlet 16a, and the lower blowing air 14b is blown substantially vertically between the lower surface 18b of the lower blade 18 and the lower outlet 16b. At this time (step 2), the blowing air is blown out along the upper part of the room and the floor surface so that the feeling of airflow due to the warm air disappears and the entire room can be quickly and uniformly heated.

Further, each of the vertical airflow direction control plates has a curved shape so that the upper blade is concave when the upper blade is oriented in a substantially horizontal direction, and the front surface is convex when the lower blade is oriented in a substantially vertical direction. To

Further, after the upper blade of the vertical airflow direction control plate is oriented in a substantially horizontal direction, the lower blade is oriented in a substantially vertical direction, and then the upper blade is inverted to move in a substantially horizontal direction.

When the upper blade of the vertical airflow direction control plate is oriented in a substantially horizontal direction and the lower blade of the vertical airflow direction control plate is oriented in a substantially vertical direction, between the upper blade edge portion and the lower blade upper surface portion 2. Make a slight gap in.

[0013]

As described above, according to the wind direction control method of the air conditioner of the present invention, the warm air is divided into the substantially horizontal direction and the substantially vertical direction.
By dividing the flow in the direction, the temperature of the entire room can be raised quickly without giving a feeling of air flow, and further, the temperature distribution in the entire room can be made uniform.

Further, each of the vertical airflow direction control plates has a curved shape so that the upper blade is concave when the upper blade is oriented in a substantially horizontal direction, and the front surface is convex when the lower blade is oriented in a substantially vertical direction. By doing so, it is possible to easily divide the blowing air.

When the upper and lower airflow direction control plates are in a substantially horizontal direction, the lower blades are oriented in a substantially vertical direction, and then the upper blades are inverted so that the upper and lower airflow direction plates are turned in a substantially horizontal direction. It is possible to reduce the noise caused by the turbulence of the blown air and to easily perform the diversion.

When the upper blade of the vertical airflow direction control plate is oriented in a substantially horizontal direction and the lower blade of the vertical airflow direction control plate is oriented in a substantially vertical direction, between the upper blade edge portion and the lower blade upper surface portion. By providing a slight gap, it is possible to eliminate noise due to pressure increase on the wind direction control plate and deterioration of shunting performance due to re-merging in the leeward direction, and it is possible to eliminate interference between the upper and lower blades.
