Description

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

2. Description of the Related Art As shown in FIG. a temperature setting means 4 for setting the temperature of the electric heater 1, a switch 5 for starting preheating, and a timer 6 for setting the preheating time.
, L controls the energization of the electric heater 1 based on the temperature detected by the temperature detection means 2 and the signal from the temperature setting means 4.
i1l i wholesale means 7 were provided.

This configuration had the effect of turning on the switch 5, setting the preheating time with the timer 6, and automatically changing the setting from preheating to an appropriate temperature. (For example, Jikko 48-8
(No. 146 Publication) Problems to be Solved by the Invention However, in the method using a timer as described above,
It takes time to turn on the preheating switch and set the timer, and setting the timer is difficult and difficult because the crystallinity rises differently depending on the room temperature and the type of intruder. Also, it is not always the case that you go to bed within 7 hours of setting the timer, and if you go to bed earlier than the set time, you will receive a blanket if you do not turn off the timer. There was a problem that the +'rA' level was too high to cause illegal ig.

Therefore, an object of the present invention is to solve the conventional problem W and to automatically set the heater temperature at the time of going to bed, thereby realizing a comfortable sleeping environment.

Means for Solving the Problems In order to achieve this object, the present invention provides a blanket body provided with an electric heater and a 4+;'1 degree detection means for detecting the temperature of the electric heater, and temperature 1 throwing means for setting the temperature, acceleration sensing means for detecting the body temperature of the wooden blanket, and bed entry determining means for determining whether a human body has entered the bed based on the output of the acceleration sensing means 1iiJ. and a setting changing means for changing the temperature of the temperature film temperature setting means n'lS in response to signals from the temperature setting means and the bed entry determining means, and a signal from the temperature sensing means;
A control means is provided for controlling the supply of electricity to the electric heater based on a difference between the signal from the setting changing means.

Operation In the above configuration, the electrical current of the present invention is passed through the electric heater C based on a preset high temperature during preheating after the power is turned on, and when a human body enters the bed, the temperature at that time is The acceleration detection means detects the movement of the blanket body, and based on the detection signal, the temperature is automatically switched to the desired sleep temperature set by the user in advance using the temperature setting means, and from then on, the electric blanket is switched to the electric blanket at that set temperature. It has the effect of controlling the energization of.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 11 to 3.

In FIG. 1, an electric heater 1, temperature detection means 2 for detecting the temperature of the air heater 1, and temperature detection means 2 for detecting the temperature of the air heater 1 are arranged on the blanket body 3, and further detect the acceleration of the blanket body 3. An acceleration sensor 8 is provided in a part of the blanket body 3. 9 is a control box housing a control circuit. Fig. 2 shows a control diagram.

a temperature setting means 4 for setting the temperature of the electric heater 1; a setting changing means 11 for changing the set temperature according to a signal from a bed entry determining means 10 for determining whether a human body has entered the bed based on the output from the acceleration sensor 8; energizing the electric heater 1 according to signals from the setting change means 11 and the temperature detection means 2;
(11) b1111 (7)

The operation in the above 1'+'7j configuration will be explained using FIG. When the operation is started, preheating is started at a high temperature setting regardless of the desired sleeping temperature set by the user in advance using the temperature setting means 4.

Thereafter, an inertial force is generated in the blanket main body 3 by the user's action of putting the futon on when going to bed. At this time, the blanket body 3
An acceleration sensor 8 installed at the front detects this force and generates a 1E signal corresponding to its magnitude. This signal is received by the bed entry determining means 10, and it is determined that the sound used is a signal that the user has entered the bed, and it is transmitted to the setting changing means 11, so that the use K is switched to the desired sleep temperature set in advance.
The means 7 connects the electric heater 1!
, 't1'C, are automatically controlled. For this reason, the user does not have to take the trouble of manually resetting the t1111 degree when going to bed. I can now sleep comfortably without having to worry about waking up.

Effects of the Invention The 711 air blanket of the present invention provides the following effects.

By detecting the acceleration of the blanket body, it is determined whether the user has entered the bed, automatically changes the set temperature, and energizes the 7F air heater! Since it is a b1ζ formation that changes 1k,
When preheating after starting operation, the blanket is quickly heated to a high temperature setting, and after the user goes to bed, the blanket can be automatically switched to a temperature suitable for sleeping.

Therefore, if you reset the temperature setting when you go to bed, it will save you a lot of time, but at the same time, you may forget to set the appropriate temperature and fall asleep, and you may wake up in the middle of sleep. You can sleep comfortably without having to worry about stuffing up.
