Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner control device for providing comfortable air conditioning for a human body while being in bed.

2. Description of the Related Art As a conventional technique related to the present invention, a control technique using a thermostat is widely known. In addition, there is a technology in which a user is provided with a means for informing the air conditioner of the current degree of comfort to a remote controller of the air conditioner.

Problems to be Solved by the Invention However, with the control technology using a thermostat, even if the room temperature can be kept constant to some extent, comfortable control for the user is not guaranteed. Even when the user feeds back the current comfort level, the user must operate the remote controller or the like each time, and cannot give feedback information during sleep, for example.

The present invention is intended to solve such a conventional problem, and aims to perform more comfortable air conditioning control by feeding back information of a user to an air conditioner even when the user is sleeping. .

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides an on-bed detection device for detecting the presence of a human body in bed, a body motion detection device for detecting the movement of a human body while in bed, A perspiration detection device that detects perspiration of a human body inside, a computing device that inputs detection signals from the presence detection device, the body motion detection device, and the perspiration detection device,
A transfer device connected to the arithmetic unit and configured to transfer a control signal to an air conditioner.

Effect By the means described above, the air conditioner can be controlled according to the sweating of the user, and the air conditioning can be comfortably controlled for the user even while the user is sleeping.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a block diagram of the embodiment. In the drawing, reference numeral 1 denotes a pillow with electrodes in which at least a pair of electrodes is attached to a contact surface with a human body.

Reference numeral 2 denotes a piezoelectric element using polyvinyldene fluoride or the like. This piezoelectric element 2 is connected to a filter 3. The filter 3 extracts a potential change of the piezoelectric element 2 caused by a body motion and a potential change of the piezoelectric element 2 caused by a heartbeat, and outputs a body motion detection signal and a presence detection signal, respectively. That is, when the user sleeps quietly on the piezoelectric element 2 as shown in FIG. 1, the heartbeat of the user is detected, the bed detection signal is “H (high)”, and the body motion detection signal is “L”. (Low) ". When turning over, the body motion detection signal also becomes “H”. On the other hand, when luggage or the like is placed, the body motion detection signal becomes “H” immediately after it is placed, but the occupancy detection signal remains “L”. As described above, the on-bed detection device and the body motion detection device can be configured by the piezoelectric element 2 and the filter 3.

The pillow with electrodes 1 and the filter 3 are connected to the arithmetic unit 4. The arithmetic unit 4 detects a perspiration detection signal from the pillow 1 with electrodes,
The control signal to be sent to the air conditioner 5 such as an air conditioner is determined based on the presence detection signal and the body movement detection signal from the filter 3.

FIG. 2 is a perspective view of the pillow 1 with electrodes. In the figure, reference numeral 6 denotes a pillow body, on which a plurality of electrodes are attached on a surface with which the user's neck contacts. In the figure, 7,8,9,10 are plus electrodes, 11,1
2,13,14 are negative electrodes. When sweating occurs, the resistance value between the two electrodes decreases, so that sweating can be detected. In determining the number of electrodes and the mounting position, the user should consider turning over. The sweat detection signal is sent to the arithmetic unit 4 via the connection lead 15.

FIG. 3 is a flowchart of the arithmetic processing in the arithmetic unit 4. In this embodiment, it is assumed that the cooling operation of the air conditioner is controlled. In the arithmetic processing, first, the presence detection signal is determined. If the occupancy detection signal is "L", it enters a waiting state until it becomes "H".

If the presence detection signal is "H", the body movement detection signal is examined next. Here, the reason why the body movement is detected is to prevent the perspiration detection signal from malfunctioning due to a potential change between the electrodes due to the body movement. Therefore, when the body motion is detected, the process returns to the first process.

If no body movement is detected, that is, if the user is at rest in bed, the perspiration detection signal is checked. Since the sweat detection signal is an analog electric resistance value, there are three states, that is, a state in which there is no change in a certain range and a state of decrease and increase. If no change is found, the process returns to the first process. If the electric resistance value shows a decrease and the air conditioner is stopped at that time, the air conditioner is operated. If the air conditioner is already operating, lower the set temperature of the air conditioner. If the electric resistance value indicates an increase and the air conditioner is stopped at that time, the process returns to the first process.
If the air conditioner is operating and the cooling capacity has already been minimized, the air conditioner is stopped. If not, increase the set temperature. In either case, the process returns to the beginning.

The above processing flow can be easily applied to the heating operation.

Effects of the Invention As described above, according to the present invention, even if the user is sleeping, it is possible to notify the air conditioner of the sweating state,
Air conditioning control can always be performed at a set temperature that is comfortable for the user.
