Abstract

PURPOSE:To permit to maintain comfortable indoor circumstance at all times by a method wherein the physical value of a room to be air-conditioned or human body at a time when perspiration has been detected is detected and the detected result is operated and corrected to memorize it, thereafter, the content of the memory is compared with the physical value of the room to be air-conditioned or the human body after the memory to control the equipments of the air-conditioning machine. CONSTITUTION:When the human body feels hotness and sweats during room cooling operation, in which cool air is blown off toward the upper part of the room to reduce the difference of indoor temperature distribution, the value of resistance between electrodes 9 attached to the skin surface of the human body is reduced and the value of electric current is increased. The increase of electric current is measured by an ammeter 13 and is decided by a comparator 14 whether the value means sweating condition or not. At this moment, the indoor temperature, detected by a thermistor 9, is operated by an operating unit 16 to memorize it into a memory unit 17. Then, a motor control unit 18 rotates a motor 7 to turn an air direction control vane 5 and change the direction of blow-off air stream downward whereby cool air hits the human body directly for a predetermined time and uncomfortable feeling may be excluded.

Description

[Detailed description of the invention] Industrial applications The present invention relates to an air conditioner.

BACKGROUND ART Conventionally, methods have been proposed that directly detect physiological information of the human body and control equipment based on that information to improve comfort. For example, in Japanese Utility Model Application Publication No. 58-104717, it is assumed that there is a strong correlation between the skin surface temperature of the human body and the arh, and the skin temperature is fully detected and the equipment is controlled based on the detected value.

Further, Japanese Patent Application Laid-Open No. 56-63510 discloses a means for obtaining a comfortable feeling by detecting the state of sweating and changing the air blow rate accordingly.

Problems to be Solved by the Invention However, the above-mentioned means have the following problems.

(1) Means for detecting skin temperature In general, skin temperature in a comfortable state varies from person to person, and has a distribution as shown in FIG. However, the values used to control the equipment are average values obtained through subjective reporting experiments with a large number of subjects, and do not take into account differences between men and women of all ages or individual differences. Therefore, even if a device is controlled based on such a universal value, the environment created by the device may not be comfortable for everyone.

(2) Means for detecting sweating The fact that the human body sweats is already quite unpleasant, and even if you control the equipment after detecting sweating, the feeling of comfort will not last long. However, there is a drawback that the discomfort of sweating occurs intermittently.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an air conditioner that can provide a comfortable environment for the user regardless of individual differences, and that can continue to maintain this condition without being impaired.

Means for Solving the Problems In order to achieve this object, the present invention provides a perspiration detection means for detecting perspiration of a human body, a physical quantity detection means for detecting a physical quantity of an air-conditioned room or a human body, and a perspiration detection means for detecting perspiration of a human body. a calculation section that performs calculations based on the detection result of the physical quantity detection means when a predetermined perspiration is detected; a storage section that stores the calculation results of the calculation section; and a detection of the contents of the storage section and the physical quantity detection means. and a control unit that controls the equipment based on the results.

Operation In the above configuration, while the device is operating, physical quantities such as temperature, humidity, or body temperature in the air-conditioned room are detected at the point when sweating of the user is detected, and calculations such as multiplying the detection result by a predetermined coefficient are performed. By comparing the calculation results with subsequent physical quantities such as temperature and humidity and controlling the operation of equipment, air conditioning is performed without causing unpleasant conditions such as sweating.

Embodiment Below, as an embodiment of the present invention, FIGS. 1 to 5 show a case where the perspiration state and room temperature are detected to control the deflection of the blown air flow.
This will be explained using figures.

In FIG. 1, reference numeral 1 denotes an air conditioner main body of the present invention, which has a heat exchanger 2, an air blower 3, etc. inside. The air outlet 4 is provided with a wind direction side tilt H5 as means for deflecting the air flow. The wind direction control blade 5 is connected to a motor 7 via a shaft 6,
Rotates automatically.

Roughly the suction port 8 has a 71 installed indoors as a physical quantity detection means.
A thermistor 9 for detecting A is provided.

FIG. 2 shows a circuit diagram of the sweating detection means 100, in which sweating is determined based on changes in current value due to resistance changes between electrodes 11, fixed pressure (source 12, ammeter 13, and electrodes 11 attached to the skin surface). It consists of a comparator 14.

FIG. 3 is a block diagram of the control device 15, an FF detection means 10, a calculation section 16 that calculates the output of the thermistor 9 when the FF detection means 10 detects a predetermined amount of perspiration, and a calculation section 16.
A storage section 17 that stores the calculation results obtained by the above, and a motor control section 18 that controls the rotation of the motor 7 based on the contents of the storage section 17 and the instantaneous indoor temperature detected by the thermistor 9 are shown.

The operation when performing cooling operation in the above configuration will be described.

During normal cooling operation, the direction of the blown airflow is directed upwards in the room, as shown in Figure 4, to reduce the indoor temperature distribution and to prevent the cold air from directly hitting the human body 19, causing discomfort due to the feeling of cold air. I try not to let it happen.

During this cooling operation, when the human body 19 feels hot and sweats, the resistance value between the electrodes 9 attached to the skin surface decreases and the current value increases. This is measured by an ammeter 13, and a comparator 14 determines that the value indicates a sweating state. At that point, a predetermined value of the room temperature detected by the thermistor 9 is sensed by the calculation section 16 and stored in the storage section 17 .

Then, the motor control unit 18 rotates the motor 7, thereby rotating the wind direction sub-H5 to direct the direction of the blowing air downward as shown in FIG. This eliminates all discomfort.

Thereafter, the indoor temperature fluctuates depending on factors such as turning on and off the compressor and opening/closing the door.
By rotating the , it becomes possible to eliminate the discomfort before sweating starts.

This means of directing airflow to the human body 19 by rotating the wind direction control vanes 5 is a method that, when the set temperature is set relatively high in on-off control, causes discomfort due to the heat when the temperature is near the on point of the heat source due to the differential of the equipment. However, at this time, the above-mentioned control eliminates this unpleasant feeling, so that even if the set temperature is set high, the user does not feel any unpleasant sound and can achieve energy-saving operation.

Effects of the Invention As described above, the air conditioner of the present invention provides the following effects.

(1) The device is configured to detect sweating that corresponds to discomfort in the human body and control the device based on the results, so it eliminates the problem of differences between students using methods based on statistically determined comfortable axial rotations. Judging everyone's discomfort regardless of
It is possible to perform appropriate control over this.

(2) Detect the physical quantities of the air-conditioned room or the human body at the time sweating is detected, calculate and correct the detection results and store them, and then compare the stored contents with the subsequent physical quantities of the air-conditioned room or the human body. Since we perform test 1a on the equipment, we can detect discomfort in the human body before sweating begins and take appropriate measures to counter it. As a result, it is possible to consistently maintain a comfortable indoor environment that does not cause discomfort.
