Description

[Detailed description of the invention] Industrial applications The present invention relates to a control device for an electric blanket.

BACKGROUND OF THE INVENTION As shown in FIG. 4, this conventional ring electric blanket has a blanket body provided with an electric heater 1 and temperature detection means 2 for detecting the temperature of the electric heater, and a temperature sensor for setting the temperature of the electric heater. This electric blanket is composed of a temperature setting means S and a control means 8 that controls the energization of the electric heater based on the signal from the temperature setting means 5 and the signal from the temperature detection means 2. Even if you feel hot while sleeping, you can If I didn't change the setting scale, the power would be turned on at the same set temperature.

Problems to be Solved by the Invention However, with the above configuration, if the temperature inside the bed increases while sleeping, the user will feel hot and uncomfortable, and the setting scale must be changed, which is very time consuming. Another problem is that if you go to bed without changing the setting scale, you will sweat and your throat will be dry when you wake up.

The present invention aims to solve these problems by detecting the movement of a human body and correcting the set temperature.

Means for Solving the Problems In order to solve the above problems, the electric blanket of the present invention has the following features:
A blanket body equipped with a FIl air heater, temperature detection means for detecting temperature, and body movement detection means for detecting body movement based on temperature change, heat flow change, pressure change, etc., and temperature setting means for setting the temperature of the electric heater. and determining means for determining body movement based on a change in the signal from the body movement detecting means, integrating and storing the number of body movements, and correcting the set temperature of the electric heater based on the signal from the temperature setting means and the signal from the determining means. The apparatus includes a setting correction means and a control means for controlling the electric heater based on the difference between a signal from the setting correction means and a signal from the temperature detection means.

Effect The present invention has the above-described configuration, and when the temperature inside the bed is high while sleeping, the number of body movements increases in order to adjust the body temperature.
This body movement is detected and the set temperature of the electric heater is adjusted, so you can sleep comfortably without waking up or becoming uncomfortable due to the heat, and your throat becomes less dry due to sweating. In addition, there is no need to worry about setting the temperature and adjusting the temperature like in the past.
1 Example Below, is an example of the present invention? The explanation will be given based on FIGS. 1 to 1A of the accompanying drawings.

In FIG. 1, an electric heater 1, a temperature detection means 2, and a body movement detection means 3 are arranged in a blanket body 4, a temperature setting means 5 for setting the temperature of the electric heater 1, and a body movement detection means 3. A determining means 6 that determines whether the body has moved based on a change in the signal of the means 3, and also integrates and stores the number of body movements, and a set temperature of the electric heater 1 is corrected based on the signal of the temperature setting means 5 and the signal of the determining means 6. This electric blanket is composed of a setting correcting means 7 that adjusts settings, and a control means 8 that controls energization of the electric heater 1 based on the difference between a signal from the setting correcting means 7 and a signal from the temperature detecting means 2.

As the body movement detection means 3, there is a method of detecting by blanket temperature, pressure, heat flow, etc., and it is determined that there is a body movement based on the change in the signal detected by these methods, and the set temperature is corrected according to the body movement, and the temperature is determined to be hot and uncomfortable. Before you talk, it lowers the temperature setting so you can always sleep in a comfortable state.

As shown in FIG. 2, the determining means 6 has a storage section 61 that stores the signal from the body movement detection means 3, and a determination means 6 that determines whether the body has moved based on changes in the signal from the body movement detection means 3 and the signal from the storage section 61. a calculation unit 6a that integrates and stores the number of body movements determined by the determination unit 62; and an output that sends a signal to the set temperature correction unit to correct the set temperature based on the signal from the calculation unit 63. It consists of a section 64 and a display section 65 that displays the state of body movement based on signals from the calculation section 6a.

In FIG. 3, the controller is provided with a display section for indicating the state of body movement, but a separate display section may be provided.

Body movement can also be a measure of health.

In the above configuration, when the temperature inside the bed is high, the number of body movements increases in order to relieve the heat. Since this body movement is detected and the temperature setting of the blanket is adjusted, you will feel less uncomfortable due to the heat, you will sweat less due to the heat, and your throat will be less dry when you wake up. effective.

In addition to the effects of the invention, the electric blanket of the present invention provides the following effects.

(1) If you feel hot while sleeping, the set temperature can be adjusted based on your body movements without having to change the settings, so you don't have to worry about it.

(2) While falling asleep, even if the bed is high, the set temperature is adjusted according to body movements, so you can sleep in a comfortable state without waking up to heat and feeling uncomfortable.

(3) Since you don't feel hot as much, your throat becomes less dry due to sweating.
