Abstract

PURPOSE:To make it possible to obtain the temperature distribution responding to the individual feeling of the users by controlling the average temp. of a first and second heaters with a first temp. controller and also controlling the individual temps. of these heaters with a second temp. controller so that these temp. are separated set above and below the average temp. CONSTITUTION:A carpet main body is composed of a blanket texture 1, the first heater 2 and the second heater 3 wired inside the blanket texture 1, and a cord terminal 4. And in a controller 5 to control the temperature, a temperature controller (first temperature controller) 8 to control the temperature of the whole blanket, and a heat-cooling/feet-warming controller (second temperature controller) 9 to convert the ratio of keeping the head-cooling and the feet- warming condition responding to the taste of the user are furnished, and the head-cooling/feet-warming controller 9 can convert the temperature settings at the breast and at the feed of the blanket main body in the reverse directions of the rise and the fall in stages. Consequently, the temperature distribution of the blanket main body suitable to the user can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heating device for sleeping such as an electric blanket.

BACKGROUND OF THE INVENTION Conventional electric blankets have a uniform heater wiring method within the blanket body, and therefore the temperature distribution of the electric blanket is uniform.

In some cases, the heater wiring is cold-head-heat wiring, and some have adopted a head-cold-foot heat heating system.

Problems to be Solved by the Invention However, in such electric blankets, the pattern of temperature distribution is determined in any case, and the reality is that the distribution of warmth does not match.

Women in particular are sensitive to cold, and their feet feel especially cold. However, if you raise the temperature of the electric blanket, you may experience problems such as tightness in your chest, and some people dislike electric blankets.

The present invention solves the above-mentioned problems and provides a heating device for sleeping that can adjust the temperature distribution state of the main body.

Means for Solving the Problems In order to solve the above problems, the sleeping warming device of the present invention includes:
a main body, a first heater provided on the main body on a side corresponding to the upper body of the user, a second heater provided on the side corresponding to the lower body of the user, and the first heater and the second heater. a control device that independently controls power supply to the heater, the control device has a first temperature control section and a second temperature control section, and the first temperature control section has a first temperature control section and a second temperature control section. The temperature of the heater is adjusted to either increase or decrease, and the second temperature adjustment section adjusts the temperatures of the first heater and the second heater in opposite directions of increase and decrease.

Function: In the above configuration, the second temperature control section controls the first temperature of the main body.
By changing the temperature settings of the first heater and the second heater in opposite directions, a temperature distribution state of the main body suitable for the user can be obtained.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1, 2, and 3.

FIG. 1 shows the entire electric blanket as an embodiment of the sleeping warming device of the present invention.
The blanket body is composed of a first heater 2, a second heater 3, and a cord opening 4 wired inside. The temperature controller 5 also has a cord opening 4 at the end of the cord 6.
A connection part 7 for electrically connecting the controller 5 and the controller 5
There is.

FIG. 2 shows the temperature control controller 5, which includes a temperature control section 8 for controlling the temperature of the entire blanket body;
There is a head-cold-foot-heat adjustment section 9 that can change the ratio of head-cold-foot-heat according to the user's preference, and the head-cold-foot-heat adjustment section 9 changes the temperature settings of the chest and feet of the blanket body in steps in the upward and downward directions. This is what I did. In this embodiment, it is assumed that adjustment can be made in six stages A to F.

This gradual change in temperature will be explained with reference to FIG. 3.

That is, this is a state diagram in which a person 11 is sleeping on a mattress 10 and is covered with an electric blanket 12 of this embodiment. In this state diagram I
The area marked with is the chest side, and the area marked with ■ is the side of the feet. This shows the relationship between the temperature of the electric blanket 12 in six stages A-F. In A-F of the cold head and feet heat adjustment section 9, A is the chest side and the feet side. The temperature difference is the smallest, and the lower the switch is, the larger the temperature difference becomes.

Effects of the Invention As is clear from the description of the embodiments above, the heating device for sleeping according to the present invention adjusts the temperature rise and fall of the first heater and the second heater in the first temperature adjustment section, Since the temperatures of the first heater and the second heater can be adjusted in opposite directions, it is possible to obtain a temperature distribution that suits each user's physical sensation. Therefore, you will not feel unsatisfied in your feet (lower body) or feel tight in your chest (upper body), and people who have had tight chests and do not use electric blankets or women whose feet are particularly cold. Also, it can satisfy elderly people who are dissatisfied with electric blankets because the warmth is not suitable for them.
