Description

  The present invention relates to a thermal apparatus having a PTC characteristic that is applied to an affected part of a human body or a desired location and directly or indirectly warms that part.

  As a heating device for directly warming the human body, for example, it is known to heat-treat an affected part due to nervous system damage or joint pain caused by cervical spine compression. However, the nichrome wire heat source used for the heating is a thermostat or a temperature sensor, and a large-scale device with temperature control is required to finely respond to the user's situation and the state of the affected area.

  On the other hand, a heat source having a PTC characteristic in which electric resistance rapidly increases and current does not flow at a required temperature has a temperature control function. Therefore, there is no need for a controller for controlling the temperature, and there is safety that it does not overheat. In addition, it is a heat source suitable for warming the human body because it is easy to radiate far infrared rays at a set temperature. However, even if such a heat source having PTC characteristics is used as a planar heating element, it is weak against frequent bending or extreme acute bending, and it is necessary to reinforce it with a hard material to compensate for the weak point. Therefore, it has been difficult to obtain adhesion to a human body part having a delicate curved surface.

  The above-mentioned heating equipment using nichrome wire as a heat source requires a controller that adjusts the temperature, and there is a danger of overheating due to failure, a problem of high power consumption, and harmfulness even though it is in contact with the human body. There is a problem that so-called electromagnetic wave emission is large. In addition, a heating device consisting of a heat source with a PTC characteristic that easily emits a large amount of human-friendly far-infrared rays is difficult to adhere to various parts of the human body when the heating element shape is planar, and it is frequently bent and extremely sharp It was a heat appliance that was also weak against bending and had limited application and application. Further, there has not been provided a heating tool using a heating element as a heat source that is linear, freely bendable, and has flexible PTC characteristics.

  The present invention focuses on the fact that a linear heat source having PTC characteristics (hereinafter referred to as a PTC linear heating element) can be bent or wound around a necessary portion. Covered with a body to make a heating device. For the inner cover that directly covers the heating element of the coated body, a material that does not lose flexibility is used to protect the heat source, such as fiber woven fabric or non-woven fabric, and the outer cover that covers the outer cover is flexible. It is made of a fabric that is brushed, has a good touch, is harmless to human epidermis, and is breathable, such as a natural fiber fabric. In addition, the heating device has a structure that can be easily fixed by adjusting the length of the heating element according to the circumference of the human body part to be heated, such as the neck. When the PTC linear heating element wire is used as a planar body, for example, in a loop shape or a spiral shape, it is preferable to cover the inner and outer surfaces of the inner sheath and the outer sheath or one surface to form a heating device.

  Among the heating elements, if a heating element having a peak wavelength between 6 and 10 μm is used as a heat source, the diameter of a human erythrocyte is about 8 μm. I can expect. This wavelength band is also an absorption wavelength band for substances constituting the human body such as protein and fat, and is suitable for warming the human body. Furthermore, using a heating element having PTC characteristics as a heat source makes it easy to obtain the desired far-infrared wavelength, easily controls the temperature automatically, and provides an energy saving effect. Further, by providing low temperature burn prevention and good tactile sensation to the human body part by the inner and outer coatings covering the heating element, it is possible to expect blood flow promotion and health promotion effects according to the user.

It is the front view which made a part of linear heating appliance in Example 1 of the present invention a section. It is the front view which showed the usage example which winds the same thermal appliance around a neck. It is a side view of the example of use. It is the top view which fractured | ruptured partly with the thermal appliance in Example 2 of this invention, and exposed the linear heat source partially. It is sectional drawing of the thermal appliance of the Example 2.

  A flexible PTC linear heating element with a flexible string shape that is wrapped with an inner jacket and outer jacket on the outside, like a string muffler on the neck, etc. In addition to those that make it easy to wrap, some linear heat sources are used in combination to make it easy to wrap around various parts with bandages, supporters that make it easy to apply to the knee, etc., and bend the linear heat source For example, it can be used in the form of a loop or spiral and spread into a surface, and can be incorporated into a part of a carpet, blanket or clothing.

  Embodiment 1 of the present invention will be described below. A PTC linear heating element having a peak wavelength between 6 and 10 μm is used as the heat source 1, and the inner jacket 2 that wraps the PTC linear heating element does not interfere with transmission of far infrared rays, does not impair flexibility, and has flexibility. In addition, the heat source is protected by, for example, a fiber woven fabric or a non-woven fabric. The outer cover 3 that covers the outside is made of a fabric that is not flexible, has raised hair, feels good, is harmless to the human epidermis, and is breathable, such as natural and man-made fiber fabrics. This linear heating device can be fixed by adjusting the length easily with, for example, string or magic tape (registered trademark of Kuraray Co., Ltd.) according to the peripheral length of the body part to be heated, such as the neck. Thus, in Example 1, a structure that can be adjusted by the rubber ring 4 was adopted. The outer dimensions excluding the power cord are 40mm in diameter and 850mm in length. The power supply used was AC 100V or a battery. Reference numeral 5 denotes an energization line. 2 of an Example is a front view of the usage example wound around the neck, and FIG. 3 is the side view.
