いった問題があった。Problems to be Solved by the Invention The conventional method has a problem that the temperature inside the bed becomes unsuitable for falling asleep when the time set by the timer deviates from the actual bed-on time. Even if the time set by the timer and the actual bed time match, if the room temperature is low at the time of entering the bed, or if the body temperature is low when entering the bed or after entering the bed after waking up midway There has been a problem that cold movement into the bed due to floor movements, cold nightwear, and the human body cooling the inside of the bed lower the temperature inside the bed, resulting in an inappropriate temperature for falling asleep. Also, due to such a decrease in the temperature inside the bed, it is necessary for the occupant to temporarily raise the set scale, and in addition, the person may fall asleep with the set scale raised and feel uncomfortable during sleep. There was a problem.

れる。Operation With this configuration, when the power is turned on, preheating is started at a high temperature setting regardless of the preset temperature, and when it is detected that a person has entered the floor by a signal from the human body detection means, the setting correction means The correction value of the set temperature suitable for falling asleep is calculated from the subsequent heater temperature and the rate of change of the heater temperature, and the heater is energized by the correction value. This correction operation is continued for a certain period of time, and thereafter, it is automatically returned to the proper temperature setting set by the temperature setting means. Even if you wake up during bedtime due to a toy etc. and then re-enter the bed, the setting correction means continues the same correction operation at the time of falling asleep for a certain period of time, and then automatically adjusts to the appropriate temperature setting set by the temperature setting means. Will be returned.

温度と毛布温度の変化率を用いることも考えられる。In this way, just by turning on the power and setting the set temperature, the temperature adjustment is automatically performed from preheating to the optimum temperature when entering the bed, and after that, it switches to the optimum temperature setting for sleep. There is no difference between the time and the actual time of entering the bed. Also, when entering the bed or after entering the bed after waking up midway, the temperature setting that is suitable for falling asleep is corrected from the heater temperature and the rate of change of the heater temperature. Therefore, you can fall asleep in a comfortable state. In the above embodiment, the heater temperature and the rate of change of the heater temperature were used to calculate the correction temperature, but as another embodiment, if the blanket temperature is detected by the temperature detecting means, the blanket temperature and the blanket temperature are calculated to calculate the correction temperature. It is also conceivable to use the rate of change.

In FIG. 1, the present invention is provided with an electric heater 1 and a temperature detecting means 2 and a blanket body 3, and a temperature setting means 4 for setting the temperature of the temperature detecting means 2 and the electric heater 1 and a human body. Setting correction means 6 that corrects the set temperature by a signal from the human body detection means 5 that detects entering and waking up depending on the presence / absence, and energization to the electric heater 1 is controlled by signals from the setting correction means 6 and the temperature detection means 2. It is an electric blanket composed of the control means 7. When power is turned on with this electric blanket, preheating is started at a high temperature setting regardless of the preset temperature set by the temperature setting means 4, and it is set that it is detected that a person has entered the bed by a signal from the human body detection means 5. The correction unit 6 calculates a correction value of the set temperature suitable for falling asleep by the signal from the temperature detection unit 2 and outputs the correction value to the control unit 7. This correction operation is performed by the setting correction means 6
The internal timer unit continues for a certain period of time, and thereafter, the temperature is automatically switched to the proper temperature setting set by the temperature setting means 4. In this case, the correction value of the set temperature is determined by the combination of the heater temperature and the change rate of the heater temperature (or the blanket temperature and the change rate of the blanket temperature with time) as shown in FIG. There is no excess or underage, and the correction value is automatically switched to the appropriate temperature setting by the timer, so you can sleep comfortably without hassle.
In addition, as shown in FIG. 2, even when the user wakes up due to a toilet or the like while sleeping and then enters the bed, when the signal from the human body detection means 5 is detected, the setting correction means 6 sets the set temperature for a certain time. Because the correction is made, even if the body is cold, the inside of the bed is warm and there is no need to change the setting scale as in the conventional case, and it is possible to fall asleep in a comfortable state without trouble.
