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, when there is one vertical wind direction plate and the blowing temperature is low in order to prevent cold draft during heating operation, the wind direction plate is moved substantially horizontally. There is known a method of directing the wind direction plate downward to raise the temperature near the floor surface when the blowing temperature becomes higher.

[0003]

However, since the wind direction is limited by one upper and lower wind direction plate, it takes time to raise the temperature near the floor surface. Moreover, it is difficult to extend the reach of warm air without increasing noise.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a wind direction control method for an air conditioner capable of quickly creating a comfortable living environment with head cold foot temperature. ..

[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. A vertical wind direction control plate having a plate and a horizontal wind direction control plate for controlling the left and right wind directions are provided. The upper blade of the vertical wind direction control plate has an upper surface portion 1 and a lower surface portion 1, and the lower blade has an upper surface portion 2 and a lower surface portion 2. And 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, and a blower circuit for the air conditioner. Outlet temperature detection means for detecting the outlet air temperature of the outlet formed on the outlet side, the control means for controlling the vertical wind direction control plate driving means and the horizontal wind direction control plate driving means by the outlet temperature, and the human body position detection. In the air conditioner having a human body position detecting means for detecting the blowout temperature during the heating operation of the air conditioner, if the heat exchanger temperature is lower than a preset temperature, the upper blade of the vertical wind direction control plate and When the lower blade is oriented in a substantially horizontal direction and the heat exchanger temperature becomes higher than a preset temperature, the upper blade and the lower blade of the vertical airflow direction control plate are directed downward, and the vertical airflow direction control plate The upper blade is directed downward from a position parallel to the lower blade of the vertical wind direction control plate, and the lower blade of the vertical wind direction control plate is directed upward from a position parallel to the upper blade of the vertical wind direction control plate. It is a thing.

[0006]

With the above-described structure, the present invention realizes local heating by increasing the wind speed of the warm air due to the contraction effect and quickly raising the temperature near the floor surface.

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 blower temperature detection unit 13 for detecting the temperature of the blower fan 15 that circulates the blower air 14 inside the heat exchanger 12 and the room, and the blowout air 14 that passes through the blowout port 16 and the blowout wind 14. Upper blade 17 and lower blade 1 for controlling the wind direction of the more inflowing flow

The blowing temperature detecting means 22 and the human body position detecting means 2 are
3, an indoor control unit (microcomputer) 24, a vertical airflow direction control plate drive means 25 for driving the upper and lower blades, and a horizontal airflow direction control plate drive means 26 for driving the left and right blades.

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 temperature t of the blowing air is detected by the blowing temperature detecting means 22 and the preset temperature T1, T is set in the indoor control section 23.
2 (T1 <T2), and when t <T1, the control signal 1 is sent from the indoor control section 24 to the vertical wind direction control plate driving means 25.
And the blowing air 14 is blown out in a substantially horizontal direction by directing the upper blade 17 and the lower blade 18 in a substantially horizontal direction (step 1).

When T1≤t <T2, the control signal 2 is transmitted from the indoor control section 24 to the vertical wind direction control plate driving means 25.
The upper blade 17 and the lower blade 18 in the downward direction, the upper blade 17 in the downward direction from the parallel position with the lower blade 18, and the lower blade 18 in the upward direction from the parallel position with the upper blade 17. By directing, the blown wind 14 causes the lower surface part 117-b of the upper blade 17 and the upper surface part 218-a of the lower blade 18.
Is blown during (step 2). At this time, the blown air can increase the wind speed due to the contraction effect and quickly raise the temperature near the floor surface.

When t ≧ T2, the control signal 3 is output from the indoor control section 24 to the vertical airflow direction control plate drive means 25, and the upper blade 17 is directed further downward and the lower blade 18 is further directed upward. Point it (Step 3). At this time, the blowing air with the increased temperature is further contracted to prevent the blowing of the blowing air.

Further, the human body position detecting means 110 detects the human body position, the control signal 4 is output from the indoor control section 24 to the vertical wind direction control plate driving means 25, and the contracted blown air is directed to the front of the human body position. To

The human body position detecting means 110 detects the human body position, the control signal 4 is sent from the indoor control section 24 to the vertical wind direction control plate driving means 25, and the control signal 5 is sent from the indoor control section 24 to the left and right wind direction control plate driving means 25. The blown-out air that is output to and is directed toward the front of the human body.

[0014]

As described above, according to the wind direction control method of the air conditioner of the present invention, the warm air is discriminated by the blowing temperature, so that the reaction quickly starts from the lowest temperature zone that a person feels comfortable and the contraction effect is obtained. As a result, the wind speed can be increased, the temperature near the floor can be quickly raised, and a comfortable living environment with a cold head temperature can be quickly created.

Further, by increasing the contraction effect as the blowout temperature rises, the blown air of which the temperature has risen is further contracted and the rise of the blown air can be prevented.

Further, the position of the human body is detected, and the contracted blowing air is blown out in the vicinity of the human body position by moving the upper and lower blades of the vertical wind direction control plate, respectively, so that the user is away from the indoor unit. Can also raise the temperature near the floor of the user.

Further, by detecting the position of the human body and blowing out the contracted blowing air to the front of the human body position by moving the upper and lower blades of the vertical wind direction control plate and the left and right blades of the horizontal wind direction control plate, respectively. No matter where it is used indoors, local heating can be realized by raising the temperature near the floor surface of the user.
