Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a sleeping environment condition adjusting device that can adjust sleeping environment conditions such as temperature and humidity according to a pattern desired by a sleeper.

[Prior Art] In order to achieve a comfortable sleep, it is necessary to adjust the temperature, humidity, etc. Electric blankets, electric futons, and the like have been conventionally used as means for achieving this purpose, and more recently, sleeping devices equipped with heating and cooling devices have been considered.

[Problems to be Solved by the Invention] In the case of electric blankets, etc., temperature control in these means is carried out by attaching a temperature sensor such as a thermostat to an appropriate place on the blanket, etc., and detecting the surrounding temperature.
On/off control is performed to maintain a preset temperature, and in the case of a sleep device, a temperature sensor is attached to the hot/cold air delivery section to detect the temperature of the hot/cold air delivery section, thereby performing the same operation as above. ing. However, the physiologically optimal temperature conditions during sleep are
It is not necessarily constant; it not only changes depending on factors such as time and temperature, but also varies greatly from person to person.
Comfortable conditions cannot be maintained simply by keeping the temperature constant.

Environmental conditions other than temperature, such as humidity, have not been considered much in the past, but problems similar to those described above arise even when these adjustments are made.

The present invention has been made to solve this problem, and by programming target values to change sleeping environment conditions such as temperature and humidity according to a predetermined pattern during bedtime, the present invention can be adjusted to suit the state of the sleeper. It is an object of the present invention to propose a sleeping environment condition adjustment device that can adaptably adjust the environmental conditions.

[Means for Solving the Problems] In order to achieve the object, the present invention solves the following problems:
A setting unit that sets target values in advance as a program so that sleeping environment conditions such as humidity are changed according to a predetermined pattern from the time the sleeper falls asleep to the time the sleeper wakes up; A measuring device measures the sleeping environment conditions around the sleeper's body using sensors corresponding to each condition, and a measurement signal from the measuring device is compared with each target value by the setting section to detect a deviation, and the deviation is detected. It consists of air conditioning equipment, etc. that automatically regulates the corresponding environmental conditions based on the environmental conditions.

[Example] Hereinafter, a sleeping environment condition adjusting device of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the sleeping environment condition adjusting device of the present invention.

The adjustment device of the present invention can set target values, measure environmental conditions, compare and judge target values and measured values, operate equipment such as air conditioners based on deviations between target values and measured values,
As shown in FIG.
This is realized by 0.

Setting the target value is to preset the target value at each time as a program so that sleeping environment conditions such as temperature and humidity change according to a predetermined pattern from falling asleep to waking up. This setting is performed by having the setting section 11 store change patterns of temperature, humidity, etc. given by relays, timers, etc.

The target value change pattern is based on changes in external temperature, humidity, etc., heat radiation pattern of the sleeper, sweating pattern,
The sleeper himself/herself can freely set the settings, taking into consideration his/her preferences. For example, the temperature can be set as shown in FIG. 2A or B, and the humidity can be set as shown in FIG. 3.

In addition, the temperature and humidity change pattern settings are as follows:
Each can be done independently, but since the two are closely related, one (e.g. temperature) can be set with priority and the other (humidity) can be set subordinately, or one (e.g. humidity) can be set as a priority. can be set to be constant and only the temperature to change.

Target value setting can be done in advance, not only just before going to bed, and once set, it can be used repeatedly. In addition, when setting the target value, it is also possible to store a plurality of change patterns of temperature, humidity, etc. in advance in the setting unit 11, so that the sleeper can appropriately select and use the desired pattern before going to bed. .

After setting the target value, when the sleeper starts the control device 10 and others and goes to bed, target signals such as predetermined temperature, humidity, etc. are output as the sleeping time elapses. At the same time, the measurement device 20 starts measuring the sleeping environment conditions.

The sleeping environment conditions were measured using bed, pinerest,
Sleeping environment conditions such as temperature, humidity, atmospheric pressure, and oxygen concentration around the sleeping person's body surrounded by bedding members such as futons and blankets are detected by corresponding sensors, and feedback signals based on the environmental conditions are supplied.

As a device used for measurement, for example, as shown in FIG. 1, a temperature sensor 21 and a detection circuit 22,
A measuring device 20 consisting of a humidity sensor 23 and a detection circuit 24 is used. The temperature sensor 21 is, for example, a thermistor, thermocouple, resistance temperature detector, or semiconductor.
A PN junction temperature sensor, bimetal, or other device that can convert temperature changes into electrical signals can be used, and the humidity sensor 23 can be, for example, a moisture-sensitive ceramic equipped with a Kanthal heater, a selenium-deposited film moisture-sensing element, or a germanium moisture-sensing element. etc. can be used.

These sensors 21 and 23 are preferably installed near the sleeping person's body in order to measure temperature and humidity including changes such as heat radiation from the sleeping person's body and sweating. The detection circuits 22 and 24 are circuits capable of detecting temperature and humidity information corresponding to the temperature sensor 21 and humidity sensor 23, respectively, such as a bridge circuit,
It consists of a differential amplifier circuit, etc.

Note that this measuring device 20 can also be used to measure the sleeper's heat radiation pattern, sweating pattern, etc., which are necessary for setting the target value.

Comparing and determining the target value and measured value is to detect the deviation between the target value set at the relevant time and the actual environmental conditions.The target signal and the measured signal are compared to determine if they match, do not match, or are large or small. etc., and outputs an adjustment signal based on the deviation. For this reason, an adjustment section 12 is provided in the control device 10, and this adjustment section 12
consists of comparators, amplifiers, etc.

The operation of a device such as an air conditioner is performed by outputting an operation signal that controls the operation of a device that regulates environmental conditions, such as the air conditioner 30, in response to the adjustment signal. For example, air conditioner 30
Signals for turning on/off the blower 31 or increasing/decreasing the amount of air blown, switching the heating/cooling device 32, changing the heating/cooling temperature, turning the humidity control device on/off, etc., are output independently or in appropriate combinations, and each Target blower 31, heating/cooling device 32, humidity control device 33
Operate so that it performs the specified operation.

Note that the above-mentioned target value setting, comparison/judgment, and operation can be performed using a computer such as a microcomputer. According to this, temperature, temperature,
A plurality of change patterns of target values such as humidity can be set, and the patterns can be easily changed, selected, and combined, and the temperature, humidity, etc. can be controlled to best suit each sleeper.

Next, an application example of the environmental condition adjustment device of the present invention will be explained. FIG. 4 is a configuration diagram showing an example in which the device of the present invention is applied to a sleep aid device. The example shown in the figure is
