Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a heating mat that is used by laying it on the floor, and more specifically, it is connected to a heat exchanger to supply a heat medium liquid into the tube. Concerning a heating pine that circulates and heats the body.

(Prior Art) Conventionally, a floor heating device is known in which a pipe made of a copper tube or other good thermal conductor is laid on the surface of a heat-resistant resin plate, and a plate made of an aluminum plate or other good thermal conductor is provided on the top surface. However, this device has the disadvantage that it cannot be folded because it is entirely made of a rigid body, making it difficult to store and transport.

Therefore, a heating mat was proposed in Utility Model Application No. 59-33540, in which a flexible heat-resistant tube was laid on the surface of a flexible heat-insulating mat to facilitate storage and transportation.

(Problem to be solved by the invention) However, with this method, only a flexible heat-resistant tube is laid directly on the heat-insulating mat, so the part that comes into contact with the heat-resistant tube is warm, but the other parts are almost completely heat-free. This has the disadvantage of causing temperature unevenness on the surface of the heating mat.

(Means for Solving the Problems) The object of the present invention is to obtain a heating mat that is free from such inconveniences. A heating mat comprising a flexible tube that circulates a heat transfer liquid laid smoothly, and at least a sheet made of a super-absorbent material of the sheet and the tube is covered with a flexible waterproof sheet. .

(Function) Now connect both ends of the tube to an external heat exchanger,
When forcing the heat transfer liquid into the tube,
The heat held by the heat transfer liquid is released as it passes through the tube.

This allows you to take heat from the floor.
There is no particular difference in the function of heating mats previously proposed, but in the present invention, a sheet made of a super absorbent material impregnated with liquid and a heating medium placed in contact with the sheet are circulated. Since the super absorbent material includes a flexible tube, the heat radiated from the tube by the liquid contained in the super absorbent material can be dispersed almost uniformly over the entire surface of the mat, and the heat can be stored in the liquid. , the heat can be maintained for a considerable period of time even after the circulation of the heat transfer fluid has been stopped.

(Example) In the drawing, 1 indicates a sheet 4 made of a super absorbent material impregnated with a liquid, and a flexible tube 3 for circulating a heat transfer liquid, which is laid in a meandering or spiral manner so as to be in contact with the sheet 4. A heating mat is shown in which at least a sheet 4 of the sheet 4 and tubes 3 made of a super-absorbent material is covered with a flexible waterproof sheet 2.

To explain this in more detail, the one shown in FIGS. 1 and 2 has a heat-resistant rubber or synthetic resin material on the top surface of a waterproof sheet 2a that has insulation and cushioning properties and is made of closed-cell foam urethane or the like. The tube 3 is laid in a meandering manner, and the tube 3 is
A non-woven polyacrylate-based super water-absorbing material sheet 4 with only the laying area cut out is soaked with water or water containing antifreeze solution, and the sheet 4 is placed in the tube 3.
are laid so that they are in contact with each other, and a waterproof sheet 2b is applied to the upper surface of these, and both waterproof sheets 2a, 2b are laid out so that they are in contact with each other.
The tubes 3 and the sheet 4 made of the super-absorbent material were covered with the waterproof sheet 2.

However, as shown in FIG. 3, the sheet 2 made of the super-absorbent material is laid over the entire upper surface of the waterproof sheet 2a which has insulation and cushioning properties, and then the tube 3 is placed on top of the sheet 2. A waterproof sheet 2a is applied to the top surface of the waterproof sheet 2a, and the peripheral edges of the waterproof sheets 2a and 2b are bonded together by adhesive or other means in the same manner as described above, or as shown in FIG. Waterproof sheet 2
After laying the heat-resistant tube 3 on the top surface of a, the sheet 2 is applied from the top surface, and the waterproof sheet 2a is applied on top of this, and the peripheries of the waterproof sheets 2a and 2b are tied together in the same manner as described above. , the sheet 4 and the tube 3 may be covered with a waterproof sheet 2.

In the above-mentioned embodiment, the waterproof sheet 2a on the lower surface is made of an independent foam mat, thereby providing the heating mat 1 itself with both insulation and cushioning properties on the lower surface. As shown in the figure, a sheet 4 made of a super-absorbent material is covered with a waterproof sheet 2 such as a resin film, and this is removably laid on top of a heat-insulating mat 5 on which the tubes 3 are laid. As shown in Figure 6, a sheet 4 made of a super absorbent material is laid on the top surface of the tube 3, covered with a waterproof sheet 2 such as a resin film to form a single body, and this is attached to and detached from the top surface of the heat insulating mat 5. They may be laid freely, especially when configured as shown in Figures 5 and 6.
The heat insulating mat 5 portion, the super absorbent material sheet 4 and the heat resistant tube 3 can be stored separately, making storage and transportation easier.

The super-absorbent material 4 is not limited to the non-woven fabric as described above, but may be a woven fabric or a powder, and the super-absorbent material 4 is not limited to a resin-based material. , starch-based, carboxyl-based, etc.

As shown in Fig. 7, this device connects both ends of the tube 3 to a heat exchanger A that utilizes part of the heat of a heat equipment such as a heater equipped with an oil burner or other burner, and The heating medium liquid is forcedly circulated in the tube 3 by the interposed pump B, and when used, the heating mat 1
It is used with a carpet applied on top.

(Effects) The present invention includes a sheet made of a super absorbent material impregnated with a liquid and a flexible tube that circulates a heat transfer liquid and is laid so as to be in contact with the sheet, and the tube and the sheet are connected to each other. At least a sheet made of a super-absorbent material is covered with a flexible waterproof sheet, so that the entire product is flexible and can be folded or rolled up into a compact size that is convenient for carrying and storing. The heat radiated from the tube by the liquid impregnated in the super-absorbent material can be uniformly distributed over the entire surface of the heating mat, and it may be possible to obtain almost uniform heat from the entire surface of the heating mat. The liquid contained in the super-absorbent material can also store heat, and the heating effect can be maintained for a considerable period of time even after the circulation of the heat transfer liquid is cut off.
