In this case, the correction value for the set temperature is determined from the environmental temperature as shown in Figure 5, so even if the environmental temperature is low and the human body is cold, you can fall asleep in a comfortable state.Furthermore, the correction value is automatically adjusted to the appropriate temperature setting by a timer. If you don't want to change the settings, you can easily fall asleep in a comfortable state by changing the setting scale to 1.

Furthermore, as shown in Fig. 2, even if you get up to go to the bathroom or the like in the middle of sleep and then go back to bed, it is detected that you have entered the bed by the signal from the human body detection means 5, and Z5 and the setting change means change the set temperature for a certain period of time depending on the date. Since the bed is warm even if your body is cold, there is no need to change the setting scale like in the past, and you can fall asleep in a comfortable state without any hassle.

As shown in FIG. 3, the human body detection means includes a storage section 3a that stores a signal from the temperature detection means that detects the temperature of the electric blanket, and a calculation section 3 that calculates the difference between the stored temperature and the current humidity.
b, and a determining unit 3c that determines whether a person goes to bed or wakes up based on the presence or absence of a human body based on a signal from the calculation unit 3b. Further, the stranger detection means having the above-mentioned structure may have a simple structure such as a bedtime/wake-up switch.

As shown in FIG. 5, when the setting correction means 8 receives a signal from the human body detection means 6, the setting correction means 8 sets a low correction value when the room temperature is high, depending on the room temperature in the bedroom detected by the environmental temperature detection means 6. ,
When the room temperature is low, the calculation means 6a calculates a high correction sensitivity and outputs it to the control means 9. This correction operation is performed by timer 7.
When the signal from the timer 7 is input, the signal from the temperature setting means 4 is output as is, and the electric heater is energized at the desired temperature set in advance by the resident. is controlled.

Effects of the Invention The electric blanket of the present invention has the following effects: (1) When the power is turned on, it automatically starts up at a high temperature setting, and when you go to bed, it automatically sets a corrected temperature suitable for falling asleep for a certain period of time. The temperature setting is then switched to the appropriate temperature for sleeping, so there is no discrepancy between the timer theft time and the actual time you go to bed, unlike with one-timer systems, so you can go to bed in a comfortable state.
I can fall asleep.

(2) Since the corrected temperature is determined by the environmental temperature, the person can fall asleep comfortably even if the environmental temperature is low and the human body is cold.

(a) Even if you wake up in the middle of sleeping and go back to bed, if the human body detection means detects that you have entered the bed, the setting correction means will temporarily correct the set temperature, so that you will not feel cold and will be in a comfortable state. You can fall asleep without having to raise or lower the temperature setting like in the past, and you won't feel hot and uncomfortable while putting your eyes into sleep, unlike when you fall asleep with the temperature set high.
