Description

[Detailed Description of the Invention] The present invention relates to a heating cloth for sleeping in which the temperature of the whole body and the front and rear parts can be changed separately.

Conventionally, this type of heating cloth has heating elements 2 and 3 as shown in Figure 1.
The front and rear parts are completely separated, and the way to use it is to energize the entire unit (heating elements 2 and 3) when pre-energizing before going to bed, and then energize it as is when warming up, or energize only the heating element 3 on the foot side. there were.

It is also possible to energize only the heating element 2 on the chest side, but in reality, it is rarely used because the feet are not heated and get cold when heating, so there are only two ways to use it, and the method of use and the user are It had the disadvantage of being limited.

The present invention has been devised to eliminate such conventional drawbacks, and one embodiment of the present invention will be described below with reference to FIG. 2.

In the figure, 1 is a cloth that allows heating wires to be wired inside.
For example, a blanket.

2 is a heating wire A that is meanderingly wired at the same intervals over almost the entire length of the blanket 1, and 3 is a heating element B that is partially wired along the heating element A at a predetermined location of the blanket 1 that comes near the feet during warming. ,
4, 5, and 6 are plugs, connectors, and cords on the main body side that connect the blanket 1 and a controller 7, which will be described later, and 7 has a built-in temperature control circuit for the heating elements A2 and B3, and By operating the knob 8, the controller is equipped with a knob 8 for switching energization to the heating element A2 and B3, and a state in which power is energized to both the heating element A2 and the heating element B3 at the same time, and a state in which the power is energized only to the heating element A2. It is configured so that it can be arbitrarily switched between the state and the state where only the heating element B3 is energized.

9 is a power supply cord, and 10 is a power plug. To explain a specific example of use in the above configuration, as a preliminary energization before going to bed, the knob 8 of the changeover switch (not shown) of the controller L-roller 7 is heated entirely (both the heating element A2 and the heating element B3 are energized). If this is done, the entire blanket 1 will be heated by the heating element A2, and the foot portion will also be heated by the heating element B3, resulting in a high temperature.

Therefore, immediately after going to sleep, the cold feet quickly warm up, allowing the user to sleep comfortably.

After your feet have warmed up, you don't need such a high temperature, so before you go to sleep, you can operate knob 8 of the changeover switch (not shown) again to switch to energizing only the heating element A2, and then the whole thing will be energized. The temperature is almost uniform, allowing you to sleep comfortably.

Also, depending on individual differences, some people prefer heating the entire body and a higher temperature at the feet.For example, if you are sensitive to cold, you can leave the pre-energization setting as described above and use it until the end, while others may prefer heating only the feet. Comfort can be achieved by switching to energization only on the foot side (only the heating element B3 is energized).

In other words, according to the present invention, it can be used in three ways: (1) heating the whole body with higher temperature at the feet, (2) uniform heating of the whole body, and (2) heating only the feet, and can also be used as a power saving type by switching. A wide range of heating cloths can be provided.

Furthermore, since one heating element is wired in a meandering manner at approximately the same intervals, and the other heating element is wired along the heating element, the structure is simple and can be manufactured at low cost.

In the embodiment described above, a manual switching type was used using the knob 8, but an automatic switching type can also be adopted by using a timer or the like for the changeover switch.
