DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling a wind direction of 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 one blowing plate is provided and the blowing temperature is low in order to prevent a cold draft during a heating operation, the blowing plate is moved in a substantially horizontal direction. There is known a method in which when the blowing temperature increases, the wind direction plate is directed downward to make the temperature distribution uniform.

[0003]

However, since the wind direction is limited with one vertical wind direction plate, it takes time to equalize the temperature distribution throughout the room. Also, it was difficult to make the temperature distribution throughout the room uniform without giving an unpleasant airflow feeling.

The present invention has been made in view of the above problems, and has as its object to provide a wind direction control method for an air conditioner capable of quickly creating a comfortable living environment without giving an unpleasant airflow feeling. It is in.

[0005]

In order to solve the above-mentioned problems, a wind direction control method according to the present invention comprises two upper and lower wind directions provided to an outlet formed on an 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 left and right wind direction control plate for controlling left and right wind directions, wherein the upper blade has an upper surface portion and a lower surface portion, and the lower blade has an upper surface portion and a lower surface portion. Vertical wind direction control plate driving means for independently rotating the upper and lower blades of the vertical wind direction control plate, left and right wind direction control plate driving means for rotating the left and right wind direction control plate,
An air conditioner having a heat exchanger temperature detecting means for detecting a temperature of a heat exchanger of the air conditioner, and a control means for controlling the vertical wind direction control plate driving means and the horizontal wind direction control plate driving means based on the heat exchanger temperature. In the heating operation of the air conditioner, a heat exchanger temperature is detected, and when the heat exchanger temperature is lower than a preset temperature, the upper blade and the lower blade of the vertical wind direction control plate are directed substantially horizontally. When the heat exchanger temperature becomes higher than a preset temperature, the upper blades of the vertical wind direction control plate are turned substantially horizontally,
The lower blade of the vertical wind direction control plate is directed substantially vertically.

[0006]

According to the present invention, the above structure allows the temperature of the entire room to be quickly raised without giving a sense of airflow by dividing hot air into two directions, that is, a substantially horizontal direction and a substantially vertical direction. 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 is a cross-sectional view of a blowing section of an air conditioner according to an embodiment of the present invention. In the figure, an indoor unit 11 includes a heat exchanger temperature detecting means 13 for detecting the temperature of a heat exchanger 12, a blower fan 15 for circulating blown air 14 into the room, and a blowout port 16.
And an upper blade 17 and a lower blade 18 for controlling the wind direction of the flow introduced from the blowing wind 14. In FIG. 2, the indoor unit 21 includes a heat exchanger temperature detecting means 22, an indoor control unit (microcomputer) 23, a vertical wind direction control plate driving means 24 for driving upper and lower blades, and a horizontal wind direction for driving left and right blades. Control plate driving 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 flowchart of 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. , A control signal 1 is output from the indoor control unit 23 to the vertical wind direction control plate driving unit 24, and the upper blade 17
The blowing air 14 is blown in a substantially horizontal direction with the lower blade 18 directed substantially horizontally (step 1). Also, t ≧ T
In the case of 1, the control signal 2 is outputted from the indoor control unit 23 to the vertical wind direction control plate driving means 24, and the upper blade 17 is directed substantially horizontally and the lower blade 18 is directed substantially vertically so that the upper blowing is performed. The wind 14a is blown in a substantially horizontal direction between the upper surface 17a of the upper blade 17 and the outlet 16a, and the lower blow 14b is blown in a substantially vertical direction between the lower surface 18b of the lower blade 18 and the outlet 16b. (Step 2) . At this time, the blown air is blown out along the upper part of the room and the floor surface, so that the sense of airflow due to the warm air is eliminated, and the entire room can be quickly and uniformly heated.

In addition, the upper and lower wind direction control plates are each formed into a curved surface so that the upper blade is directed substantially horizontally, the upper portion is concave, and when the lower blade is directed substantially vertically, the front surface is directed convex. (Fig. 4C)

[0011] a substantially horizontal direction over the blades of the upper and lower air direction control board improvement Keru the upper blade in a horizontal direction substantially inverts substantially after the vertically oriented a lower blade in a state (the first one from the top FIG. 4 (C)
Figure) .

When the upper blade of the vertical wind direction control plate is oriented substantially horizontally and the lower blade of the vertical wind direction control plate is oriented substantially vertically, the space between the upper blade edge and the lower blade upper surface portion 2 is increased. A small gap (Fig. 4C).
Figure) .

[0013]

As described above, according to the method for controlling the wind direction of the air conditioner of the present invention, the warm air is blown in two directions, that is, the substantially horizontal direction and the substantially vertical direction.
By diverting in the direction, the temperature of the entire room can be quickly raised without giving a sense of airflow, and the temperature distribution of the entire room can be made uniform.

The upper and lower wind direction control plates are each formed into a curved surface so that the upper blade is directed substantially horizontally and the upper portion is concave, and the lower blade is directed substantially vertically and the front portion is raised. By doing so, it is possible to easily divide the blown air.

[0015] Further, the upper blades are turned in a substantially horizontal direction by turning the lower blades in the substantially vertical direction with the upper blades of the vertical wind direction control plate in a substantially horizontal direction, so that the upper and lower wind direction control plates are operated in the horizontal direction. The noise caused by the turbulence of the blowing wind can be reduced, and the branch flow can be easily performed.

When the upper blade of the vertical wind direction control plate is oriented substantially horizontally and the lower blade of the vertical wind direction control plate is oriented substantially vertically, the upper blade edge portion and the lower blade upper surface portion are positioned between the upper blade edge portion and the lower blade upper surface portion. By providing a small gap, it is possible to eliminate the noise caused by the pressure rise on the windward and downward wind direction control plate and the reduction of the shunt performance due to the recombination of the leeward wind, and further eliminate the interference between the upper blade and the lower blade.
