In general, heat mats are provided in the health mats to provide warmth to the user. Currently, the heating sheets which are widely used are equipped with heating wires, and when the current flows through the heating wires, the heating sheet is heated by electric resistance. Electric heating sheet that heats is a direct heating method, so there is a lot of problems in use, such as high localized heating and high electricity risks and harmful electromagnetic waves are emitted during operation. It is an indirect heating type heating sheet that generates heat by heating a heated medium (usually water is used) passing through the inside.

Figure 5 is a plan view of the heat medium circulation sheet according to the prior art, Figure 6 is a cross-sectional view taken along line BB of Figure 5, the applicant filed a utility model registration application on February 24, 2005 Registered Utility Model No. 0384633.

The heat medium circulating heating sheet according to the related art is a sheet-shaped body 10 as shown in Figure 5 and 6 is made of a flexible synthetic resin, the heat medium is injected and discharged to one side of the body 10 The inlet 11 and the outlet 12 are formed, respectively, and the heat medium injected into the inlet 11 is discharged through the inside of the body 10 through the inside of the body 10 and then discharged to the outlet 12. The flow path 13 is formed in a predetermined pattern, and the receiving portion 14 is formed in a portion where the flow path 13 is not formed inside the main body 10.

Here, the accommodating part 14 is a closed space formed at regular intervals from the flow path 13, and is filled with the heat storage material 20 that receives heat from the heat medium flowing along the flow path 13 and accumulates therein. The area occupying 10) is formed to be relatively wider than that of the flow path 13, so that the heat storage material 20 prevents the flow path 13 from being compressed when pressure is applied from the outside, and the heat storage material 20 prevents the cushion function. Provide it. At this time, the heat storage material 20 is a liquid such as mineral oil, water, liquid herbal medicine.

The heat medium circulation heating sheet according to the prior art configured as described above is supplied with the heated heat medium from the heat medium supply device 30, and the heat medium supply device 30 recovers the heat medium discharged through the outlet 12 and reheats it.

In the case of liquid, the deformation is large and the compression is easy, so when the pressure is applied from the outside (for example, when the user is lying or sitting on the main body), there is an unstable side such as not steadily absorbing and slack, and the pressure is concentrated. In this case, as shown in FIG. 7, the upper and lower portions of the accommodating part 14 are in contact with each other, so that the cushion function is lost. In addition, since the receiving portion 14 is easily deformed in this way, as shown in FIG. 8, when pressure is applied from the outside over the passage 13 and the receiving portion 14, the receiving portion does not reach the passage 13. (14) could not be reliably supported, and eventually there was a problem in that the flow path 13 was severely compressed and the flow of the heat medium was stalled or delayed. Of course, these problems were more serious when the body 10 is heated by the heat of the heat medium to increase the flexibility.
