Abstract

PURPOSE:To rapidly establish an environment of comfortable feeling imparting a cool head and warm feet to a person by a method wherein an upper vane and a lower vane of a vertical air direction control plate are directed downwardly in the case that a temperature of a heat exchanger is increased more than its set temperature. CONSTITUTION:A heat exchanger temperature is detected when an air conditioner performs a heating operation and in the case that the heat exchanger temperature is lower than its set temperature, an upper vane 17 and a lower vane 18 of a vertical air direction control plate are directed substantially in a horizontal direction and air 14 is blown in a horizontal direction. When the heat exchanger temperature is higher than its set temperature, the upper vane 17 and the lower vane 18 are directed downwardly, the upper vane 17 is directed more downwardly than a horizontal position with the lower vane 18, and the lower vane 18 is directed more upwardly than the horizontal position. Blown air 14 is blown between a lower surface 17b of the upper vane 17 and an upper surface 18a of the lower vane 18, the blown air increases its air speed due to its effect of reducing flow so as to increase rapidly a temperature near a floor. As the heat exchanger temperature is increased more than its higher set temperature, the upper vane 17 is directed downward and the upper vane is directed upward. Air of which temperature is increased is reduced in its flow so as to prevent any blowing-up of the blown air.

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. 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. ..

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 heat exchange of the air conditioner. A heat exchanger temperature detecting means for detecting the temperature of the heat exchanger, a 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, and a remote controller position detecting means for detecting a remote controller position. Sky In the air conditioner, the heat exchanger temperature is detected during the heating operation of the air conditioner, and when the heat exchanger temperature is lower than a preset temperature, the upper and lower blades of the vertical airflow direction control plate are set in a substantially horizontal direction. When the heat exchanger temperature becomes higher than a preset temperature, the upper blade and the lower blade of the vertical wind direction control plate are directed downward, and the upper blade of the vertical wind direction control plate is moved toward the vertical wind direction. The lower blade of the vertical airflow direction control plate is directed downward from a position parallel to the lower blade of the control plate, and the lower blade of the vertical airflow direction control plate is directed upward from a position parallel to the upper blade of the vertical airflow direction control plate.
