Since the heat generating member 5 is placed thereon, the heat insulating material 4 is made of a material that is strong in heat and excellent in thermal barrier effect so as to reduce heat loss generated by the heat generating member 5. Such insulation is a known technique.

The heat generating member 5 is for supplying heat to the elvan rock 6, an important element for carrying out the present invention and two forms are presented.

The first presented is a mesh-type heating member 50 is configured in a grid form as shown in Figs. That is, the woven line 50a and the blade 50b are woven and terminal portions 50c and 50d for supplying power are positioned at both ends of the string 50a or the blade 50b. The terminal portions 50c and 50d are composed of good conductive metal wires such as tin-plated copper wire and silver wire with excellent conductivity.

The mesh-type heating member 50 configured as described above has excellent flexibility by using liquid silicone rubber 50e and can be widely applied to a wide range of applications.

In the manufacturing of the mesh-type heating member 50, the liquid silicone rubber 50e and the carbon black 50f are mixed in the initial mixing step as shown in the process flow diagram of FIG. 8, and the liquid silicone rubber 50e and the carbon black ( The mixing ratio of 50f) is mixed at about 100: 1 to 15 based on the mass ratio.

The reason for using the liquid silicone rubber (50e) is that it is superior in heat resistance, cold resistance, ozone resistance, and electrical insulation as shown in the thermal properties shown in <Table 1> than the polymer plastic material used for the polymer temperature (PTC) (Positive Temperature Coefficient). In addition, it has excellent flexibility.

TABLE 1

Item Liquid Silicone Rubber Polyethylene (HDPE) importance 1.04 0.94-0.97 Glass transition temperature (Tg) -118 to -132 ° C -30 ℃ Crystal melting temperature (Tm) - 137 ℃ Coefficient of thermal expansion (10 ^-6 / k ^-1 ) 270 150 Continuous use temperature 190 ℃ 80 ~ 90 ℃ In particular, since the coefficient of thermal expansion (270 × 10 ⁻⁶ · K ⁻¹ ) of the liquid silicone rubber 50e is about twice as high as that of polyethylene (PE, 150 × 10 ⁻⁶ · K ⁻¹ ), the mesh-type heat generation The member 50 has a self-controlling resistance heating function. Representative physical properties of the carbon black 50f have a particle size of 40 nm or less, as shown in Table 2, and require physical properties in the form of a highly conductive structure. <Table 2> Item  Air Space Rate (%) Primary Particle Diameter Number of Primary Particle (× 10 ¹⁵ piece / g) Conductive Carbon Black 60 40 38 After mixing as described above, in the stirring step, the diluent (toluene, etc.) is added to about 0 to 100% based on the mass ratio of the liquid silicone rubber (50e), where the stirring is performed, where carbon black (50f) When the content is small, the fluidity of the conductive composition is ensured without adding a diluent. The reason for adding the diluent is to improve the fluidity of the conductive composition upon stirring. After the stirring step as described above, the stirred conductive composition is coated with a thickness of 0.1 mm conductivity to a mold having a structure of a predetermined shape and cured according to the curing time as shown in Table 3. <Table 3> Curing Temperature Curing time  Room temperature 4 days-1 week 150 ℃ 5 to 10 minutes 200 ℃ 1 to 5 minutes The mesh-type heating member 50 manufactured as described above measures the first specimen composed of the conductive carbon black (50f) 10% content and the second specimen composed of the conductive carbon black (50f) 8% content to measure the temperature-resistance characteristics. This is shown in <Table 4>. TABLE 4 Temperature (° C) Resistivity (ρ · cm) Example 1 Example 2 20 91 - 30 129 150 40 144 220 50 156 267 60 170 312 70 187 416 80 208 468 90 250 625 100 267 939 110 312 1300 120 407

As can be seen in Table 4, the mesh-type heating member 50 exhibits a self-controlling resistance heating characteristic in which the resistance increases in volume when the temperature-resistance characteristic increases in temperature, and thus is effectively applied to the stone bed of the present invention. can do.

Next, the magnetic control resistance heating mechanism will be described with reference to FIGS. 9 and 10.

9 is a cross-sectional view of the degree of orientation in the microstructure of the conductive carbon black (50f) in the liquid silicone rubber (50e) at room temperature, Figure 10 is shown in the liquid silicone rubber (50e) in the temperature is raised above room temperature The conductive carbon black 50f has a microstructure in cross section of the degree of orientation.

The electrical conductivity is agglomerated carbon black (50f) structure between the conductive carbon black (50f) particles with a liquid silicone rubber (50e) and a fine space, the minute space acts as a potential barrier and thermal fluctuation (thermal fluctuation) ) Electrons are tunneled (tunneling current) beyond this microscopic space.

Self control resistor heating function according to the present invention uses a tunneling current (tunneling current). It flows between spaces when the space between them is kept within 1 nm and is very sensitive to the distance, changing exponentially inversely with the change of distance.

Therefore, as the temperature is increased as shown in FIG. 10, the space between the minute spaces is widened, the electrical conductivity is lowered, and the resistance value is increased, thereby supplying heat to the elvan.

In addition, the mesh-type heat insulating member 50 is generated an anion beneficial to the human body in the carbon black (50f), the anion is discharged to the outside of the bed through the vent hole (3a) of the bottom member 3 is the air around the bed To provide anion.

Thus, the heated jade 51 transfers heat to the elvan rock 6 which is in contact with it, and at the same time, transfers the characteristics of the jade 51 to benefit the health of the user.

Jade is known as a special mineral that emits 에너지, a life energy. Recently, many research institutes, including the Korea Research Institute of Standards and Science, have been actively researching and experimenting with the efficacy of jade. Jade emits a wavelength of 8-14um, which is very suitable for the human body, and it absorbs energy and resonance of the human body, thereby activating the latent potential of the human body. have.

To explain the specific effects of jade in detail, jade broadly strengthens human energy and energy, activates oxygen abundantly (about 30%), supplies clear blood, promotes blood circulation and metabolism, and improves the viscosity of blood. Recover well and keep it alkaline.

In addition, jade prevents the proliferation of abnormal cells, helps to restore normal cells, reduces pain and reduces stress, releases harmful accumulations (waste, mercury, lead, etc.) in the body, clears the head, and clears the eyes and ears. Purgatory is called "star of cancer conquest" in each Chinese hospital.
