Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a control device for an electric blanket comprising a plurality of electric heaters.

BACKGROUND ART As shown in FIG. 4, a conventional electric blanket of this type includes a blanket main body 3 provided with a plurality of electric heaters 1 and a temperature detection means 2 for detecting the temperature of the electric heaters 1, 10
Temperature setting means 4 for setting the degree of lagoon, and heater switching means 7 for switching the heater to turn on electricity according to the user's preference.
and a control means 8 for controlling the energization of the electric heater based on the difference between the signals from the temperature setting means 4 and the temperature detection means 2 in the heater energized by the signal from the heater switching means 7. .

Problems to be Solved by the Invention However, with the above configuration, when sleeping in a cold room, the temperature of the entire bedding and blanket is low and it feels cold when entering the bed, so first, all heaters are energized to warm the entire blanket. When the temperature rises, it is necessary to switch the heaters by energizing only the specific heaters to be warmed and stopping the energization of unnecessary heaters, which is very time-consuming and has the problem that it is easy to forget to switch the heaters.

Furthermore, if you go to bed with only a specific part of the heater energized when you go to bed, and the room temperature has dropped significantly since you went to bed, you may feel cold because the temperature of the entire blanket will drop in conjunction with the room temperature.

The present invention aims to solve such conventional problems, and aims to detect the room temperature and switch the heater depending on the room temperature.

Means for Solving the Problems In order to solve the above problems, the electric blanket of the present invention includes a blanket body provided with a plurality of electric heaters and a temperature detection means for detecting the temperature of the electric heaters; A temperature setting means for setting the temperature of the heater, a room temperature detection means for detecting the room temperature at which you sleep, and a heater that automatically switches the energization to the electric heater based on a signal from the temperature detection means and a signal from the room temperature detection means. An electric blanket comprising: a switching means; and a control means for controlling energization to the heater based on a difference between the temperature detecting means and the temperature setting means in the electric heater that is energized in response to a signal from the heater switching means. .

Effect of the present invention With the above-described configuration, the heaters to be energized are automatically switched depending on the room temperature. When the room temperature is high, only a specific heater is energized, and when the room temperature is low, more heaters are energized. You can sleep comfortably even when the weather is large or throughout the year.

EXAMPLE Hereinafter, an example of the present invention will be described based on accompanying drawings FIGS. 1 to 3.

1 and 2, a plurality of electric heaters 1 and temperature detection means 2 for directly or indirectly detecting the temperature of the electric heaters 1 are disposed on the blanket body 3, and the temperature of the electric heater 1 is a temperature setting means 4 for setting the room temperature, a room temperature detection means 6 for detecting the room temperature at which one sleeps, and a signal from the temperature detection means 2 to turn on electricity according to a signal from the room temperature detection means 6 when the temperature of the blanket exceeds a certain temperature. A heater switching means 7 which determines the heater and switches the heater; and 51, -7 which energizes according to a signal from the heater switching means 7. This electric blanket is composed of a control means 8 for controlling the supply of electricity to the electric heater 1.

In the above configuration, the operation of an embodiment of the present invention will be explained using FIG. 3. For example, in the case of an electric blanket in which the Totoku electric heater shown in Fig. 2 is divided into four parts: chest IA, abdomen IB, foot IC1 and peripheral area 1D, first, when the power is turned on, energization of all the heaters is started, and the temperature detection means When the blanket temperature reaches TloC (a temperature at which you do not feel cold when entering the bed) based on the signal from the room temperature detection means 6, the heater to be energized is determined based on the signal from the room temperature detection means 6, and the heater switching means 7 automatically switches the heater on. A switch is made.

In this case, the room temperature is R1°C or higher...peripheral heaters R1 to R
2°C...Peripheral foot heater R2~R3°C
・・・・・・10 feet and 10 abdomen heaters in the surrounding area R3°C or less・・・・・・・All heaters are energized, and the heaters are switched as the room temperature decreases, so if there is a large temperature fluctuation on -day However, it can cope with the cold mornings, and - The heater switches automatically throughout the year, so you can sleep in comfortable conditions without having to switch the heater manually like in the past.

Effects of the Invention As described above, the electric blanket of the present invention provides the following effects.

(1) When the power is turned on, all heaters automatically start energizing, and when the blanket temperature reaches a certain temperature, the heater to be energized is determined based on the room temperature, and the heaters are automatically switched. There is no need to switch the heaters when the overall temperature has warmed up, which saves time and effort.

(≦When you go to bed, the entire blanket is warm and comfortable so you can fall asleep.

(3) Since the heater is switched depending on the room temperature, -
When the temperature fluctuates rapidly during the day, especially when the room temperature drops in the morning, a comfortable bed temperature is always maintained even when the room temperature is low, so that one can sleep comfortably and there is no need to change the heater, which saves time and effort.

(4, 1, - The heater can be switched depending on the room temperature throughout the year, so you can sleep comfortably, and there is no need to switch the heater, which saves time and effort.
