Abstract

PURPOSE:To cool or heat only one part of a room where men exist and improve efficiency by a method wherein an air conditioner is equipped with a human body detecting sensor, an information processing device, determining the direction of airflow, and a flap driving device, changing the direction of a flap by a command from the information processing device. CONSTITUTION:Human body detecting sensors 1-9 are constituted of a pyroelectrical infrared ray sensor, for example, and detect amount of heat generated by human bodies near a floor surface. An information processing device 10 is constituted of a microcomputer and the like, for example, and judges the temperature of human bodies, the movement of the human bodies, the configuration and position of the human bodies by the time change of signals outputted by the human body detecting sensors 1-9. The information processing device 10 determines the driving amount of a flap driving device 11 based on the result of the judgment. The flap driving device 11 is constituted of a motor and the like, for example, and drives a flap 12 by the signal of the information processing device 10 to control the flap 12 so that the airflow arrives at a position, whereat human bodies exist and the existence is detected by the human body detecting sensors 1-9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly to determining the wind direction.

[0002]

2. Description of the Related Art In a conventional air conditioner, a flap is automatically set in a certain angle range so that the temperature of the entire room is set to a set temperature even if there are no people in the room and the wind is spread over the entire room. Is constantly changing.

FIG. 3 shows an example of a conventional air conditioner. The flap switch 14 is configured by, for example, a push button or the like, and selects a flap operation mode such as “automatic” or “manual” and a blowing direction. Flap drive 11
Drives the flap 12 according to the mode determined by the flap switch 14.

An example of the operation of the conventional air conditioner will be described in detail. In the conventional air conditioner, for example, in the "manual" mode, the user operates the flap switch 14 to change the direction of the flap 12 to a position that is considered to be optimum by the user. Also, for example, when in the "automatic" mode, regardless of the intention of the user, it is possible to uniformly blow air throughout the room.
The flap drive device 11 drives the flap 12 at a constant angle and at a constant cycle.

[0005]

In this conventional air conditioner, since the entire room is cooled (or heated), the temperature of the entire room needs to reach the set temperature in order to make a person in the room feel comfortable. There was a drawback that it cost. Further, even if there is only one person in the room, there is a drawback that the efficiency is deteriorated because the entire room is set to the set temperature.

[0006]

SUMMARY OF THE INVENTION Therefore, in order to achieve the above-mentioned object, the present invention processes a plurality of human body detection sensors for detecting the presence of a person, and processes an output signal from the human body detection sensors. An information processing device that determines the location of the air conditioner to determine the wind direction, a flap that changes the wind direction of the air conditioner, and a flap drive device that changes the direction of the flap according to a command from the information processing device are provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an air conditioner according to an embodiment of the present invention, and FIG. 2 is a view showing a state in which the air conditioner is installed indoors.

The human body detecting sensors 1 to 9 are composed of, for example, pyroelectric infrared sensors, and detect the amount of heat generated by the human body near the floor surface shown in 1'to 9'of FIG. 2, respectively. The information processing device 10 is composed of, for example, a microcomputer, and the temperature of the human body, the movement of the human body, the shape of
Also, the position of the person is determined from which of 1'to 9'in FIG. Then, the information processing device 10 determines the drive amount of the flap drive device 11 based on this determination result. Further, it outputs the correction value of the operating capacity of the air conditioner to the air conditioner control device 13. The flap drive device 11 is composed of, for example, a motor, and drives the flap 12 in response to a signal from the information processing device 10 to adjust the wind to reach the position of the person detected by the human body detection sensors 1 to 9. The air conditioner control device 12 is composed of, for example, a microcomputer, and adjusts the operating capacity of the air conditioner by controlling the power supplied to the compressor of the air conditioner according to a correction signal from the information processing device 10.

[0009]

As described above, according to the present invention, the place where a person is present is concentrated to blow air to cool or heat the room. Therefore, the time when the vicinity of the person is set temperature is shortened, and a part of the room is reduced. Efficiency is increased because only the air is cooled or heated.
