Description

[Detailed description of the invention] [Industrial application field] The present invention is based on a system in which heat generated by a heat generating means installed inside a bag-shaped thermal cover formed of a cotton flannelette sheet with a lot of naps is transmitted through a far-infrared radiation sheet. By doing so, the sheet emits far-infrared radiant energy, and the heat energy emitted by this far-infrared ray warms the body, improves blood circulation, keeps the body warm, and promotes sweating, which is used as a substitute for a sauna. This invention relates to a moist heat sheet that radiates.

[Prior Art] Conventionally, electric blankets have been used as sheet-like materials to warm the body. This has a heating element installed inside the blanket, and in addition to keeping warm while sleeping,
It was used by applying it to parts of the body that needed to be warmed, such as the joints and lower back.

[Exhibition of problems that ideas try to solve] However, the human body is not flat;
Because it is composed of curved surfaces and some unevenness, when an electric blanket is placed over the body to warm a part of the body, such as the joints or lower back, a gap is created between the body surface and the electric blanket's heat. There was a problem with the inefficiency of transmitting the information to the body. In addition, when using an electric blanket, the skin becomes red due to heat generation, but the skin does not feel moisturized, and there is almost no sweating, which makes the user thirsty and hinders the user's sense of comfort.

In view of the above-mentioned problems of the conventional method, the present invention fits closely along the shape of the body, uses thermal energy that emits far-infrared rays to comfortably warm a predetermined part of the body, and promotes blood circulation through the radiation effect of far-infrared rays. ,
The purpose of the present invention is to provide a moist thermal sheet that emits far infrared rays that promote perspiration.

[Means for solving the problem] The present invention has an electric heating element and a large number of rod-shaped heating elements inside a bag-shaped heating cover formed by sewing and fixing a far-infrared radiation sheet to the back side of a flannelette sheet with a lot of naps. It is constructed with a heat generating means made of a lead alloy.

[Function] When the moist thermal sheet of the present invention is applied to the body and electricity is applied to the electric heating element, the electric heating element is heated, and the heat is transmitted through the far-infrared radiation sheet, so that far-infrared radiant energy is radiated from the sheet. At the same time, the heat from the electric heating element accumulates heat in the many rod-shaped lead alloy rods installed inside the moist heating sheet, softening them and bending them according to the shape of the body due to their own weight, so that the moist heating sheet sticks closely to the body. Thermal energy that radiates far infrared rays is conducted to the skin through the moist heating sheet, promoting blood circulation and increasing the humidifying effect by absorbing moisture from sweat from the skin into the heating cover without evaporating to the outside. be able to.

[Example] To explain the embodiment of the present invention in detail with reference to the drawings, a far-infrared emitting sheet 2 that emits far-infrared radiant energy is sewn and fixed on the back side of a relatively thick flannelette sheet 1 with a lot of naps. At the same time, an opening 3 that can be freely opened and closed is provided at one end to form a rectangular bag-shaped heating cover 4, and a heat generating means 5 is housed within the heating cover 4.

That is, since an essential component of the present invention is that the far-infrared radiation sheet 2 is sewn and fixed to the back surface of the cotton flannelette sheet 1, the far-infrared radiation sheet 2 will be described first.

There are various substances that have far-infrared radiation characteristics, but
The material having far-infrared radiation characteristics that can be used for the far-infrared radiation sheet 2 needs to have an average far-infrared emissivity of 65% or more in the wavelength range of 4.5 to 30 μm at 30°C.

Ceramics are examples of materials that have far-infrared radiation characteristics, and particularly useful ceramics that have far-infrared radiation characteristics include alumina-based, magnesia-based, and zirconia-based ceramics. If this is further classified, alumina-based materials include alumina and mullite, magnesia-based materials include magnesia and cordierite, and zirconia-based materials include zircon and zircon sand. It is also effective to use one type or a mixture of two or more types selected from the above group.

The far-infrared radiation sheet 2 used in the present invention has a base fabric 6 made of a general-purpose fiber such as nylon, and a surface of the base fabric 6 is coated with an adhesive made of, for example, polyurethane, which has excellent reflectance. Aluminum particles, although not particularly limited, are preferably
Aluminum particles having a particle size of 10 μm or less are mixed and applied to form a reflective layer 7 having a thickness of preferably 10 to 20 μm, although there is no particular limitation, and the surface of the reflective layer 7 is coated with a layer of polyurethane. and ceramic particles made of alumina-based, magnesia-based, zirconia-based, or a composite thereof, having the above-mentioned far-infrared radiation characteristics, although not particularly limited, ceramic particles preferably have a particle size of 10 μm or less. A far-infrared emitting layer 8 having a thickness of preferably 10 to 20 μm, although not particularly limited, is formed by mixing and coating.

Further, the reflective layer 7 coated with aluminum particles and the far-infrared emitting layer 8 coated with ceramic particles are both formed with microporous pores of around 1 μm, and these pores provide air permeability. is recommended.

The reason why aluminum is used as the reflective layer 7 in the far-infrared emitting sheet 2 is that aluminum is a material with high reflective properties and heat retention properties.

A heat generating means 5 is housed through an opening 3 in a heating cover 4 formed by sewing and fixing the far-infrared radiation sheet 2 having the above structure to the back surface of the cotton flannelette sheet 1. This heat generating means 5 includes an electric heating element 9 such as an electric heating wire or an electric surface heating element (an electric heating wire is used in the embodiment) that is connected to the heating cover 4.
The fixing cloth 10 is fixed to one side of a fixing cloth 10 whose shape matches that of the fixing cloth 10, and a plurality of band cloths 11 are fixed to the electric heating element 9 at appropriate intervals, and from the other side of the fixing cloth 10. Bent part 1 with both sides bent upwards
A large number of U-shaped rod-shaped lead alloys with 2
3 through the folded part 12, and further folded the folded part 12 inward so as to sandwich the banded cloth 11.
It is fixed and formed.

The heating means 5 is covered with a covering cloth bag 14, and the covering cloth bag 14 is further covered with a synthetic resin bag 15 made of a synthetic resin sheet such as vinyl chloride or polypropylene to prevent electric leakage. It is stored in.

Note that 16 in the figure is a cord for connecting the electric heating element 9 to a power source.

To explain the operation of the embodiment of the present invention, the heating cover 4 containing the heating means 8 is placed directly on the skin of the body, the electric heating element 9 is energized, and the electric heating element 9 gradually heats up. As the temperature increases, the lead alloy 13 becomes soft and heat is stored, and since the lead alloy 13 has a heavy specific gravity, the lead alloy 13 is bent to fit the shape of the body, and the thermal cover 4 is brought into close contact with the surface of the body. While the electric heating element 9 continues to be heated, the lead alloy 13 also continues to accumulate heat, so the area of the heat generating part as a whole increases, and the heat from the electric heating element 9 is radiated by far infrared rays. The heat passes through the sheet 2 and is further conducted to the flannelette sheet 1. However, since the heat passes through the far-infrared radiation sheet 2 and is heated, the far-infrared radiation layer 8 is an efficient far-infrared radiation layer that is said to be better for health than the far-infrared radiation layer 8. Infrared radiant energy is emitted, and the heat energy emitted by far infrared rays promotes blood circulation in the human body, and at the same time, by warming the human body, it warms the body extremely efficiently, promotes sweating from the skin, and generates heat. Since the cover 4 is composed of the flannelette sheet 1 with a lot of brushing, the moisture generated by perspiration from the skin is absorbed into the heating cover 4 without being evaporated to the outside, thereby enhancing the humidifying effect. As a result, the heating cover 4 adds a humidifying effect and sweated water, which adds an effect similar to applying a warm towel to the skin, and also increases the temperature of deep tissues favorably, doubling the thermal effect.

The radiant energy radiated from the far-infrared radiation layer 8 is radiated to the human body side, and the radiant energy is radiated from the reflection layer 7.
The radiant energy is divided into the energy radiated to the side, and the energy radiated to the reflective layer 7 side.The radiant energy radiated to the reflective layer 7 side is reflected 180 degrees by the reflective layer 7 toward the human body, and the total energy is radiated toward the human body. The radiant energy is radiated in only one direction, toward the human body.

What is shown in FIG. 5 is a far-infrared ray emitting sheet 2' showing another embodiment, and this is made of a base fabric 6 with an adhesive made of, for example, polyurethane and an alumina-based sheet having the above-mentioned far-infrared radiating properties. The far-infrared emitting layer 8' is formed by coating a mixture of ceramic particles made of , magnesia-based, zirconia-based, or a composite thereof. The far-infrared radiation sheet 2' shown in FIG. 5 does not radiate radiant energy in only one direction as compared to the far-infrared radiation sheet 2, but it radiates far-infrared radiant energy, so it is useful for the present invention. It is.

Furthermore, what is shown in FIG. 6 is a thermal cover 4' showing another embodiment, which is formed by providing a recess 17 in the upper part of the cotton flannelette sheet 1 and protruding a convex part 18 in the lower part. ing. If you want to warm your neck and the back of your head, you can place the convex part 18 on your neck and the back of your head, as shown in Figure 7a, and if you want to warm your entire shoulders, you can position it as shown in Figure 7b. All you have to do is make sure your neck is in the recess 17 like this.

[Effects of the invention] Since the invention is as described above, when the electric heating element inside the thermal cover is heated, the lead alloy accumulates heat and bends along the surface of the body, so that the thermal cover comes into close contact with the body. At the same time, far-infrared radiation energy is emitted from the far-infrared radiation layer to promote blood circulation, and at the same time, the heat of the thermal cover is effectively transmitted to the body, and at the same time sweat is absorbed by the thermal cover, making it comfortable to use and reducing thirst. Moreover, since the lead alloy disposed inside the heating cover has heat retaining properties, the heat from the heating means can be used effectively, promoting sweating, and is effective as a substitute for a sauna.
