Description

[Detailed Description of the Invention] Industrial Application Field The present invention provides a sleeping device that detects when a human body goes to bed and wakes up during sleep and outputs control signals to electric blankets and air conditioners to provide a comfortable sleeping environment. Regarding.

BACKGROUND ART Conventional sleeping equipment of this type uses a pressure sensor 6 (for example, Japanese Utility Model Publication No. 56-1103) disposed on bedding 4 having a heater 3, as shown in FIG. As shown in FIG. 6, a capacitance sensor (for example,
JP-A No. 68-188081). With this configuration, when the human body goes to bed or wakes up,
It has the effect of detecting when someone goes to bed or wakes up from the pressure applied to the bedding and changes in the capacitance between the electrodes, and changes the temperature setting of the electric blanket or electric carpet to change the environment inside the bed. .

Problems to be Solved by the Invention However, with the method of detecting pressure as described above,
In addition to when going to bed or waking up, the pressure applied to the bedding changes even when the body moves during sleep, and the sensor detects this, causing the patient to be awake even though he or she is in the middle of sleep. There has been a problem in that malfunctions occur, such as outputting a signal indicating that the bed is in bed, or outputting a signal indicating that the bed is in bed due to the weight of the bedding itself or a person or object accidentally placed on the bedding. Further, there is also a problem in that the same malfunction as described above occurs in a sensor that detects a change in capacitance between electrodes.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve such conventional problems and to realize a comfortable sleeping environment by detecting body temperature at the time of going to bed or waking up, reliably determining whether to go to bed or getting up.

Means for Solving the Problems In order to achieve this object, the sleeping device of the present invention includes a human body temperature detection means for detecting the human body temperature, and an entry system for determining whether to go to bed or wake up based on the signal from the human body temperature detection means. This device is equipped with a means for determining when to wake up.

Function: With the above configuration, the sleeping device of the present invention has the function of determining whether to go to bed or wake up by detecting the human body temperature at the time of going to bed or waking up.

EXAMPLE Hereinafter, an example of the present invention will be described using FIGS. 1 to 3.

In FIG. 1, reference numeral 1 denotes a human body temperature detection means for detecting the human body temperature, and here f is a skin temperature sensor 1a that is attached to the skin surface of the human body to detect the skin surface temperature. Skin temperature sensor 1
A may be worn on any part of the human body, for example, on the wrist, head, arm, trunk, ankle, etc. with a belt, tape, etc., as shown in FIG. 2 compares the signal from the differentiation section 2a and the signal from the reference signal generation section 2b with a differentiation section 2& that differentiates the signal from the skin temperature sensor 1a, a reference signal generation section 2b that outputs a preset reference signal. This means for determining whether to go to bed or wake up is comprised of a comparison section 2C that determines whether to go to bed or wake up. Here, the signals from the skin temperature sensor 1& are output to the differentiator 2b by wire or wirelessly. In this case, the skin temperature sensor 1& was used as the human body temperature detection means 1, but the internal temperature sensor 1b detects the eardrum temperature, external ear temperature, rectal temperature, etc.
Alternatively, a clothing temperature sensor 1C worn on pajamas or the like may be used.

In the above configuration, the operation will be explained using FIG. 3. Before going to bed, for example, when changing into pajamas, the skin temperature sensor 1a is worn. Skin temperature (solid line) depends on the ambient temperature of the human body, and as shown in Figure 3, before going to bed, it is strongly influenced by the room temperature (dashed line), and after going to bed, the skin temperature rises due to the temperature inside the bed (dotted chain line). Thereafter, while sleeping, the skin temperature remains almost constant due to the heat retention properties of the bedding, but when waking up, the skin temperature drops, contrary to when going to bed. Considering the above phenomenon, in this example,
The differential value ΔTO of the skin temperature calculated by the differentiator 2a and a certain positive constant value CO preset by the reference signal generator 2b are compared and processed in the comparator 20 as follows.

That is, if ΔTo ) Co, a signal indicating admission to the bed, such as a certain positive constant value C1, is output, and if ΔTo<-Go, a signal indicating admission to the bed, for example, a certain negative constant value C2, is output, and -CO≦ If ΔTo≦CO, processing is performed to output a signal indicating that the person is sleeping, for example, zero.

Based on this output, for example, when using a sleeping heating device such as an electric blanket, preheating of the electric blanket is started when the skin temperature sensor 1a is worn, and when it is determined that the person has gone to bed through the above process, It is possible to change the setting from preheating to a temperature that makes it easy to fall asleep and sleep comfortably, and then automatically turn off the electric blanket when it is determined that you have woken up, creating a comfortable sleeping environment. can.

Effects of the Invention As described above, the following effects can be obtained by using the sleeping device of the present invention.

Detects body temperature and determines when the user goes to bed or wakes up based on this temperature change, so there are fewer malfunctions than conventional pressure sensors and capacitance sensors, and it easily and reliably detects when the user goes to bed or wakes up, and responds accordingly. Comfortable control is possible.
