Description

Electric heat mattress using thermal storage material

The present invention relates to a thermal mat that provides heat to a user.

As a heat generating means for generating heat, a heat storage material is filled with a heat storage material inside a synthetic pipe made of a free bending material, and a heating wire is inserted into the flexible plastic pipe to heat and heat dissipate the heat storage material. In particular, when not in use, it is easy to move and store by reducing the volume by folding the volume, and when used, it relates to a thermal mat containing a heat storage material and a heating wire to provide comfort when using.

Common heating means of the heating mat can be seen that the heating by heating the heating wire directly to the electricity and to generate heat by circulating the hot water.

The heating mat using a heating wire is generally referred to as an electric field plate, and as a configuration thereof, a heating wire is installed in a zigzag shape inside the front and rear covers, and a temperature controller is provided on the outside.

In addition, it is possible to see a direct heating type thermal mat using a planar heating element as a heating means instead of the heating wire.

Such a thermal mat is simple and small in volume, and has the advantage of instantaneous heat generation when an electric switch is inserted. However, such a thermal mat has a problem of generating electromagnetic waves harmful to the human body. It can be seen that the cover burns black due to excessive heat generation, and the heating wire is hardened by heat and the coating is peeled off, which causes a short circuit accident, and has a short lifespan.

In addition, in recent years, hot water circulation type thermal mats that generate heat by circulating hot water as in a heating method of a house can be seen.

The hot water circulation type thermal mat has the problem of having a hot water generator, which heats and circulates water instead of having an advantage of generating no electromagnetic waves, and does not generate heat immediately when the switch is turned on. You will see this need and the bulky problem is difficult to move.

The present invention solves the disadvantages of such hot water circulation type thermal mat or electric heat type thermal mat, and relates to a thermal mat containing heat storage material and a heating wire having only the advantages of the hot water circulation type mat and electric heating type thermal mat.

In general, the heat mat is generally referred to as an electric field plate, and a heating wire is installed in a zig-zag type inside, or is directly heated by electricity adopting a planar heating element as a heating means, and inside the mat, such as a floor heating method in a house. The hot water pipe is installed on the outside, and the hot water generating and circulation device (small hot water boiler) is connected to the outside, and the hot water circulating type heating mat that generates heat by circulating the hot water can be seen.

Such a heating wire and a thermal mat by hot water pipes can be found in numerous patents and utility model documents.

The present invention having such a configuration will be described in more detail and at the same time as follows.

The present invention is a flexible synthetic resin pipe arranged in the pipe insertion groove 12-1 in a zigzag shape on the cushion heat insulating plate 12 inside the mat 11 at the moment the user turns on the power switch attached to the temperature controller 31 ( 13) the heat transfer material 15 inserted therein generates heat to heat the heat storage material 14 filled in the flexible PVC pipe 13, and the heat storage material 14 heats the mat 11 to heat the mat 11. .

The flexible synthetic resin pipe 13 that generates heat by turning on the power switch of the temperature controller 31 is sensed by a temperature sensor S attached to the inside of the mat 11 or the heat storage material storage tank 21, and the mat When the temperature of (11) reaches the temperature set in the temperature controller 31 is automatically turned off, and when the temperature is lowered, it is automatically turned on to maintain the temperature set by the temperature controller 31.

The flexible flexible resin pipe 13 in which the heat storage material 14 and the coated heating wire 15 are inserted inside the U-shaped insert is pre-formed in the cushion insulation plate 12 having a predetermined thickness (1 to 3 cm). A nonwoven fabric 16 including a charcoal powder is adhered to the groove 12-1 in a zigzag shape, and a copper fabric 17 obtained by weaving a copper wire is attached thereto using an adhesive.

The copper fabric 17 serves as a heat transfer medium for evenly transferring the heat generated from the flexible plastic pipe 13 to the entire surface of the mat 11, and absorbs and removes electromagnetic waves generated from the heating wire 15. Will be performed.

In addition, the nonwoven fabric 16 including charcoal powder between the copper fabric 17 and the cushion insulation board 12 cushions the flexible synthetic resin pipe 13 inserted into the insertion groove 12-1 of the cushion insulation board 12.

The coated heating wire 15 having the double coating layer inserts one or two wires into the flexible synthetic resin pipe 13 to heat the heat storage material 14.

Since the nickel alloy wire 15-1 of the coated heating wire 15 does not generate heat at a high temperature but generates a low temperature, a large amount of electromagnetic waves are not generated as in a general electric field plate.

Such electromagnetic waves are negligible, but the generated electromagnetic waves are absorbed and extinguished by the heat storage material 14, and are absorbed and extinguished by the nonwoven fabric 16 having charcoal powder and the copper fabric 17 to almost eliminate electromagnetic waves. It will provide a mat 11 that does not occur.

The flexible synthetic resin pipe 13 is made of a soft material that is crimped when pressed by hand, and is usually made of soft silicone rubber or soft nylon resin or soft urethane resin or soft PVC rubber that is resistant to heat and is not easily deformed. To manufacture.

Both ends of the flexible resin pipe 13 is connected to the heat storage material storage tank 21, the heat storage material storage tank 21 is to store and store the heat storage material 14 is expanded and contracted by heat.

The heat storage material storage tank 21 has a stopper 23 for replenishing or discharging the heat storage material 14,

The stopper 23 has an air discharge hole 24 for discharging air to discharge bubbles generated from the heat storage material.

The air discharge hole 24 is to be opened and closed by the rotation of the stopper (23).

The mat 11 having such a structure is automatically heated when the coated heating wire 15 starts to generate heat as soon as the temperature controller 31 is turned on, thereby heating the heat storage material 14 and reaching the temperature set in the temperature controller 31. Will be turned off.

In addition, the inside of the mat 11 or in the heat storage material storage tank 21 is built a normal temperature sensor (S) and the temperature sensor (S) is connected to the temperature controller 31 is configured to maintain the set temperature is , When the heat storage material 14 leaks into the heat storage material storage tank 21 and the water level is lowered, the water level sensor 26 operates to cut off the power.

In addition, the heat storage material storage tank 21 may be mounted inside the mat 11 or mounted outside the mat 11.
