Abstract

PURPOSE:To provide an air conditioner capable of performing a comfortable air conditioning by a method wherein a distance between a sensor and an occupant is calculated in response to information from the sensor, an air blowing area is metered in response to the distance for the occupant and then an air speed at an air blowing port is controlled without varying the air volume. CONSTITUTION:A human body sensor 2 detects an action of occupant in a room, the action is stored in an image memory for storing the image of the occupant for every given time, an image information is digital processed by a calculation device 7 and then a presence or a absence of the occupant as well as its position, in particular, a distance between the occupant and an air conditioner is calculated. These information cause a row of direction control vanes 3 and an air blowing area variable plate 4 to be operated through an air blowing port control device 8. In the event that the human body is placed far from the air conditioner, the blowing area variable plate 4 is operated to meter an air blowing plane to cause an air speed to be fast so as to let the blown air to reach the human body. In turn, in the event that the human body is near the air conditioner, the blowing area variable plate 4 is not operated and an air blowing speed for giving an air stream not causing any uncomfortable feeling to be felt by the human body and during this operation the row of the direction control vanes 3 is concurrently directed toward the human body.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air conditioner having an air conditioning outlet.

BACKGROUND OF THE INVENTION The present invention seeks to solve the problem of an air conditioner using a human body detection sensor, for example, by simply directing the air outlet 9 toward the human body based on information obtained from the human body detection sensor, as shown in FIG. However, because the distance between two people was not taken into account, the wind was too strong for people nearby, and the wind was too weak for people who were far away.In particular, for people close to each other, the airflow was too strong and the air was too weak for people who were far away. Due to large temperature and wind speed differences,
The heat shock and changes in wind speed cause extreme discomfort. In addition, direct strong winds on the human body can have negative effects on human health.In view of the above-mentioned problems, the present invention aims to provide an air conditioner that can provide comfortable air conditioning.

Means for Solving the Problems The present invention (translation) An arithmetic device that is equipped with an outlet that blows air at a predetermined temperature at a predetermined wind speed and a sensor that detects a human body, and that calculates the distance to the human body based on information from the detection sensor. This system is characterized by controlling the wind speed at the outlet without changing the air volume by narrowing down the outlet surface in accordance with the distance from the human body.

By controlling the wind speed at the outlet according to the distance from the human body using information from the human body detection sensor, comfortable air conditioning can be achieved regardless of the person's position in the room.

Furthermore, by narrowing down the outlet surface, the flow rate at the outlet can be controlled without changing the flow rate or load.

Example Next - An embodiment of the present invention will be described based on the accompanying drawings.

FIG. 1 shows an air conditioner according to an embodiment of the present invention, in which 1 is an air outlet l'], 2 is a human body detection sensor, and 3 is a human body detection sensor.
4 is a variable blowout area plate. FIG. 2 shows a control flow, in which the human body detection sensor 2 captures the behavior in the room and stores the images in the image memory 6 every time. The image information is digitally processed by the arithmetic unit 7 to calculate the position of the human body, especially the distance from the air conditioner. These pieces of information operate the direction control blade row 3 and the variable outlet area plate 4 through the outlet control device 8 .

The specific effects and operations of this embodiment will be explained based on FIG. 3. (a) If the human body is far from the air conditioner as shown in the figure, the variable blowing area plate 4 is operated to narrow down the blowing surface and increase the wind speed so that the air reaches the human body. for,
(b) When the human body is close to the air conditioner as shown in the figure, the variable blowing area plate 4 does not operate and the blowing speed is set to a level that does not cause discomfort to the person. At this time, the direction control blade row is simultaneously directed in the direction of the person.

If there is no one to protect you, you can easily narrow down the air outlet and apply strong wind to the wall facing the wall where the air conditioner is located, and the temperature of the wall can be brought close to the set value.
It is also possible to use radiation from walls when someone enters the room.

Effects of the Invention According to the present invention, by controlling the blowing speed according to the distance from the human body, an air flow feeling independent of the position of the person in the room can be obtained, and comfortable air conditioning can be obtained.
