Description

[Detailed Description of the Invention] Industrial Application Field The present invention detects the state of the human body when going to bed and waking up, and controls sleeping heating devices such as electric blankets and air conditioners to provide a comfortable sleeping environment. Regarding sleeping equipment.

BACKGROUND ART A conventional sensor for detecting going to bed and getting up from bed uses a pressure sensor 1o (for example, Japanese Utility Model Publication No. 1103/1983) disposed on bedding 9 having a heater 8, as shown in FIG. Or, as shown in FIG.
A capacitance sensor (for example, Japanese Patent Application Laid-open No. 188081/1981) was provided to detect changes in capacitance between terminals 2& and 12b. With this configuration, when a human body goes to bed or wakes up, it is detected from the pressure applied to the bedding at that time and changes in the capacitance between the electrodes, and control is performed to change the set temperature of the electric blanket or electric carpet. It had the function of outputting signals and controlling the sleeping environment.

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, so the sensor detects this and indicates that the patient is awake even though he or she is in the middle of sleep. There is a problem in that malfunctions occur, such as outputting a control signal, or outputting a control signal indicating a state of being in bed due to the weight of the bedding itself or an object or person accidentally getting 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.

Therefore, the present invention solves such conventional problems and realizes a comfortable sleeping environment by detecting changes in the temperature of bedding due to human body heat, easily and reliably determining the state of going to bed and waking up, and controlling equipment. With the goal.

Means for Solving the Problems In order to achieve this object, the sleeping equipment of the present invention comprises a first bedding having a heating/cooling device having at least either a heating means or a cooling means, and the first bedding. a second bedding to be used together with the second bedding, a temperature detection means for detecting the temperature of the second bedding, and a rising/waking determination means for determining whether the human body is in bed or awake based on the signal from the temperature sensing means. It has been established.

Effect: With the above-mentioned configuration, the sleeping device of the present invention detects a high temperature state due to human body heat in a state of going to bed, and a high temperature state due to human body heat in a state of waking up, using a temperature detection means that detects the temperature of the second bedding used together with the first bedding. It has the function of detecting low temperature conditions caused by cold temperatures and determining whether to go to bed or wake up.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. In FIG. 1, 2 is a first bedding having a heating device 1, 3 is a second bedding to be used together with the first bedding, and 4 is a second bedding that is used together with the first bedding.
5 is a temperature detection means for detecting the temperature of the second bedding 3; 5 is a control unit 6 for controlling the heating amount of the heating means 1; and temperature detection means 4.
This control means has a built-in bed-in/wake-up determining means for determining whether the human body is in bed or awake based on signals from the controller.

In the above configuration, when entering the bed, the second bedding 3
is more strongly influenced by human body heat than the heat from the heating device 1 of the first bedding 2, and the temperature of the second bedding 3 rises due to the human body heat. This temperature increase is highest in the trunk, which has a high body temperature and a large heat capacity. Therefore, as shown in FIG. 2, the bedtime/wake-up determination means 7 uses the second bedding temperature T detected by the temperature detection means 4. If the temperature is within a certain predetermined temperature range T, ~T2, it is determined that the patient is in bed, and if it is not, it is determined that the patient is awake. Here, when the temperature detection means 4 is arranged near the head side end of the second bedding 3 as described above, the temperature is detected closer to the human body source (made of the trunk), and there is less fluctuation, so it is more accurate. Can judge whether to go to bed or wake up. Also, apart from this,
The second bedding 3 may be a pillow, and in this case, it is determined whether the person goes to bed or wakes up by detecting the head temperature with the temperature detection means 4 provided on the pillow.

Due to the above action, the temperature of the second bedding used in combination with the first bedding is detected to determine whether the person goes to bed or wakes up. This method has the effect of easily and reliably detecting the state of going to bed or waking up without any malfunctions that occur with methods that determine whether the state is in bed or awake. Therefore, a comfortable and easy-to-use sleeping device can be realized by automatically turning on and off the device or changing the set temperature depending on the presence or absence of a human body in the bed based on this detection signal.

Further, in the above embodiment, the first bedding has a heating device, but the first bedding may have a cooling device or a heating/cooling device like a blower bedding, and the same effect as above can be obtained. is obtained.

Effects of the Invention As described above, according to the sleeping device of the present invention, since the temperature of the second bedding used together with the first bedding is detected to determine the state of going to bed or waking up, it is possible to There are no malfunctions that occur with methods that use installed pressure sensors or capacitance sensors to determine whether a person has entered bed or woke up, and it is possible to easily and reliably detect the state of going to bed or waking up, and to perform optimal control accordingly. There is an effect that there is.
