[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. It is in.

[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.

In the heating operation of the air conditioner, the heat exchanger temperature t
Is detected and the heat exchanger temperature t is lower than the preset heat exchanger temperature Ta, the upper blade and the lower blade of the vertical airflow direction control plate are directed substantially horizontally (hereinafter, referred to as upward flow), When the heat exchanger temperature t is higher than the preset heat exchanger temperature Ta and lower than Tb, the upper blade of the vertical airflow direction control plate is oriented substantially horizontally and the lower blade of the vertical airflow direction control plate is generally vertical. When the heat exchanger temperature t is higher than the preset heat exchanger temperature Tb, the upper blade of the vertical wind direction control plate is directed diagonally downward and The lower blade of the wind direction control plate is directed substantially vertically (hereinafter, referred to as wide flow).

Further, the wind direction control method of the present invention is such that, in the wide flow, the upper blade of the vertical wind direction control plate is directed toward the human body position depending on the human body position.

Further, according to the wind direction control method of the present invention, in the double flow, the air volume of the blower is increased.

Further, in the wind direction control method of the present invention, when each of the vertical wind direction control plates has a curved shape and has the double flow, the upper blade of the vertical wind direction control plate has a concave upper portion, and the vertical wind direction control plate is controlled. The lower blade of the plate has a front surface that is convex.

Further, in the wind direction control method of the present invention, in the case of shifting from the upward flow to the double flow, the upper blade of the vertical wind direction control plate is placed in a substantially horizontal state, and the lower blade is oriented in a substantially vertical direction. The blades are reversed so that they are oriented in a substantially horizontal direction.

Further, the wind direction control method of the present invention is such that, in the double flow, a slight gap is provided between the upper blade edge portion and the lower blade upper surface portion.

[0011]

According to the present invention, according to the above-mentioned structure, the hot air is blown in the substantially horizontal direction and in the substantially horizontal direction and the substantially vertical direction according to the heat exchanger temperature.
Direction, diagonally downward direction and substantially vertical direction.

By controlling the upper blade of the vertical airflow direction control plate according to the position of the human body, the warm air can be sent to a desired position.

Further, warm air is passed in two in a substantially horizontal direction and a substantially vertical direction.
It is possible to quickly raise the temperature of the entire room without giving a feeling of airflow by dividing the flow in the direction and increasing the air volume of the blower.

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

Further, when the upper and lower wind 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 to be oriented in a substantially horizontal direction. The noise due to the turbulence of the blown air can be reduced and the flow can be divided easily.

Further, by providing a slight gap between the upper blade edge portion and the lower blade upper surface portion 2, the vertical wind direction control plate reduces the noise due to the pressure increase on the windward side and the diversion performance due to the re-merging in the leeward direction. It is also possible to eliminate the interference between the upper and lower blades.

As a result, it is possible to quickly create a comfortable living environment without giving an unpleasant air flow feeling.
