Description

Electric bedding with heater

The present invention relates to a thermal electric bedding, and more particularly to a thermal electric bedding formed of a heating wire coated with carbon colloidal liquid on the fiber yarn.

Electric bedding has been used for a long time when a heating element is built in a bedding material and the heating element is heated to obtain bedding at a required temperature when electricity is applied. However, since it was found that the electromagnetic wave generated from the common nichrome wire is harmful to the human body, research on electric bedding that can obtain a temperature without generating electromagnetic waves has been actively conducted, and the results have been obtained in various ways.

A representative example is a heating wire for electric bedding of the registered number No. 20-0268501 published and registered in the Utility Model Publication of the Republic of Korea Patent Office, which discloses an electric bedding heating wire that can offset the electric and magnetic fields generated from the heating wire.

Figure 1 shows an embodiment of the heating wire for the electric bedding. Accordingly, in the heating bed for electric bedding, the first insulator 22 is wrapped around the temperature sensing line 11, and the first heating wire 33 is wound around the first insulator 22 in one direction, and the first heating wire is wound. The second insulator 44 is coated on the 33, the second heating wire 55 is wound on the second insulator 44 in the same direction as the winding direction of the first heating wire 33, and the second heating wire ( 55 is sheathed 66. One end of the first heating wire 33 and one end of the second heating wire 55 are connected to each other, so that when the other end of the first heating wire 33 is connected to the positive pole (+ pole) of the plug (not shown), the second The other end of the heating wire 55 is connected to the minus pole (-pole) of the plug.

As a result, the current flows in opposite directions on the same line, so that the directions of the magnetic field and the electric field formed around the first heating wire 33 and the second heating wire 55 are opposite to each other. It is described that an effect of canceling the emission of electromagnetic waves by canceling an electric field and a magnetic field is expected.

However, as described above, although the electromagnetic wires may be blocked to some extent, the heating wires cannot be completely blocked, and the manufacturing cost increases because the heating wires must be complicated.

Thus, bedding using carbon fiber yarn as shown in FIG. 2 is proposed as a new method for blocking electromagnetic waves. This is a design of Korean Patent Application Publication No. 1999-0034899 disclosed in Korean Utility Model Publication, and according to this, the outer surface of the carbon fiber yarn is made of silicon in a common electric bedding 71 such as an electric blanket, an electric blanket, an electric blanket, an electric blanket, etc. It is described as consisting of fixing and fixing the heating wire 76 coated or coated. Reference numeral 4 is a thermostat and 5 is a plug. In addition, the above-described design makes the heating wire 76 installed in the electric bed 71 manufactured by using carbon fiber yarn having excellent thermal conductivity and excellent blocking effect of electromagnetic waves or water waves, but with excellent flexibility. By coating or coating the outer surface of carbon fiber with silicon, it can be folded freely like general bedding, and its power consumption rate is low, but its thermal efficiency is much better and safer than that of conventional copper wire or nichrome wire. It is described as having an effect.

However, in the actual use of the bedding using the carbon fiber yarn as described above, the heating line is broken due to lack of flexibility, as well as the thickness of the heating line is inconvenient to receive a continuous stimulus at the protruding part, and at the same time, Since the thick heating line is installed while reciprocating in a zigzag, there is a problem that the local heating occurs only in the installed portion.

As such, in the manufacture of electric bedding, the material of the heating wire has been continuously studied for a long time, but a product which is practically convenient to use and beneficial to health has not been produced in spite of the demand of consumers.

The present invention was devised to solve the above-mentioned long-term unsolved problem in the electric bedding and the difficulty of applying a new carbon heater. The object of the present invention is to provide a carbon heating element that does not emit electromagnetic waves, has excellent flexibility, and does not have a fear of short circuit. It is to provide a built-in thermal bedding.

The thermal electric bedding according to the present invention is connected between the bedding material 140 and a pair of verbs 119 electrodes 111 and 112 spaced at a predetermined interval, and are connected between the two electrodes 111 and 112, and mineral fiber yarns. The bedding material includes a plurality of heating wires 113 formed by coating a carbon colloidal solution at a thickness of 0.5 μm to 5 μm at one time, and an insulating material 18 to insulate the electrode on the outer surface of the 115. Carbon heating element 110 is embedded in, and

It characterized in that it comprises a controller 120 that can control the amount of heat generated by controlling the power applied to the electrodes (111, 112) of the carbon heating element (110).

At this time, the carbon heating element is further provided with auxiliary wires connected to each other while forming a mesh with each of the heating wires, and the thickness of the carbon heating element is preferably 0.5mm to 5mm.

In addition, the heating wire and auxiliary wire is preferably further coated with a thickness of 100 μm to 1000 μm with silicon, polyacryl, or polyurethane.

In addition, the fibrous yarn is cellulose-based fiber, protein-based fiber, mineral-based fiber, organic fiber yarn, semi-synthetic fiber yarn, synthetic fiber yarn, inorganic fiber yarn or basalt fiber yarn.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. However, since the change of the shape of the carbon heating element embedded in the electric bedding according to the present invention, the change of the power supply and the position of the controller, the change of the bedding provided is obvious to those skilled in the art by the present specification, so it does not depart from the scope of the present invention, Various modifications other than the embodiment can be made.

Figure 3a is a block diagram showing an embodiment of the carbon heater according to the present invention, Figure 3b is a cross-sectional view of the heating wire used in the present invention, Figure 3c is a cross-sectional view of the auxiliary line used in the present invention. 3D is an enlarged perspective view of portion A of FIG. 3A.

According to this, the carbon heater 101 is composed of a carbon heating element 110, a controller 120, and a power connection 130. The carbon heating element 110 is connected between the verbs 119 electrodes 111 and 112 spaced at predetermined intervals and the positive electrodes 111 and 112, and the carbon colloidal solution in the fiber yarn 115 is 0.5 μm at a time. It is configured to include a plurality of heating wire 113 is formed by coating to a thickness of 5㎛.

The electrodes 111 and 112 are composed of a plurality of verbs 119 (銅絲) plated with tin, and are connected to the heating wire 113 and the electric wire 131 to insulate the portions connected to the electric wire 131. Insulation material 118 is insulated. At this time, as the insulating material 118 may be used a silicon tape having a waterproof function. The applied electricity can be either AC or DC.

The heating wire 113 is provided with the fiber yarn 115 inward and coated with a carbon solution on its outer surface. At this time, the fiber yarn 115 used is natural fiber yarn (cellulose fiber yarn, protein fiber yarn, mineral fiber yarn) and artificial fiber yarn (organic fiber yarn, semi-synthetic fiber yarn, synthetic fiber yarn, inorganic fiber yarn Can be used without limitation (in particular, glass fiber yarn, basalt fiber yarn, polyester).

The carbon heating element 110 is further provided with an auxiliary wire 114 connected to the heating wire 113 and meshed with each other and assisting the heating wire 113. The auxiliary line 114 is provided with the fiber yarn 115 which is not coated with carbon inward. Fiber yarn 115 is not limited to natural fibers (cellulose fibers, protein fibers, mineral fibers) and artificial fibers (organic fibers, semi-synthetic fibers, synthetic fibers, inorganic fibers) Can be used (particularly, glass fiber yarn, basalt fiber yarn, polyester are used). The outer surface is again coated with a thickness of 100 μm to 1000 μm with silicone, polyacrylic or polyurethane. This is because the heating line 113 is more flexibly folded by the coating with silicone, polyacrylic, polyurethane, or the like, and there is no fear of a short circuit, and when too thin, the flexibility is weakened, and when too thick, the heat generating effect is lowered.

In this case, the auxiliary line 114 serves to reinforce and support the heating line 113. In the present embodiment, the auxiliary line 114 is vertically formed in the heating line 113 in the horizontal direction, but the auxiliary line 114 assists the heating line 113. Can be connected in any form. For example, a mesh may be configured to include the auxiliary line 114 positioned between the heating lines 113.

The controller 120 is connected to the carbon heating element 110 by an electric wire 131 and is configured using a technology of a conventional heating controller 120 capable of controlling the amount of heat generated. The power connector 130 is a carbon heating element ( 110 is configured to be connected to a power source to supply electricity. Therefore, when power is applied to the power connection unit 130 and the controller 120 is manipulated to generate the required heat generated by the controller 120, the carbon heating element 110 generates heat.

Next, an embodiment of a method of manufacturing a heating wire which is the most important component in the carbon heating element 110 having the above configuration will be described. First, the glass fiber yarn is passed through the carbon colloid solution heated to 400 ° C. or lower in the first step, and then transferred to the drying chamber in the second step, firstly dried to 100 ° C. or lower, and heat treated at 300 ° C. to complete the primary coating. Next, the heating wire is manufactured in three steps of passing the carbon colloid tank again and performing secondary coating in the same process as described above.

In the above embodiment, the carbon coating layer 116 is formed of two layers, but the coating layer 116 may be adjusted to one or more layers to achieve a desired specification and electrical resistance value, and when the coating is performed once The thickness is set to 0.5 μm to 5 μm.

The carbon heating element having the above-described configuration has good heat radiation efficiency due to the passage of electricity with a thin coating thickness, and there is no fear of overheating due to the constant temperature heating, and heats the air by high efficiency heat exchange. Moreover, since only the carbon colloidal solution is coated on the surface of the inexpensive fiber yarn, the manufacturing cost can be significantly reduced compared to the conventional carbon heater.

Figure 4 is a perspective plan view showing an embodiment of a thermal electric bedding according to the present invention. Accordingly, the electric bedding 100 includes a net carbon heating element 110, a bedding material 140 containing the carbon heating element 110, and a controller 120 capable of controlling the amount of heat generated by the heating element. , And a power connection unit 130 connected to a power source to supply electricity to the heating element.

The electric bedding of the present invention may include all conventional electric bedding. That is, electric blankets, electric mattresses, electric blankets, electric blankets, electric mats, electric cushions, and the like. In this case, in the case of an electric field plate, an electric mat, an electric mat, and an electric cushion, it is advantageous that heat is transferred only to an upper portion, and therefore, it is preferable to further form a heat insulating layer under the carbon heating element. The heat insulation layer may be composed of a silver foil foam material to block radiant heat and styrofoam to block conductive heat.

At this time, the bedding material 140, the controller 120 and the power connection unit 130 may be configured using conventional and known techniques.

Hereinafter will be described the function and action of the electric bedding according to the present invention. When the power connection unit is connected to a power source and the switch is turned on, heat is generated in each heating line 113 while electricity is applied to the heating heater. Since the heating value of each heating line is controlled by the controller 120, the user can operate the electric bed at a temperature suitable for the human body. At this time, since each heating line 113 is formed so as not to generate heat above a temperature at which the human body may be burned by adjusting the electrical resistance value by controlling the coating amount of carbon, safety during use is increased.

The effect of the electric bedding according to the present invention is as follows.

First, not only uses a large number of heating wires that are very thick, but also the outer surface is coated with silicon again, so the flexibility is very large, there is no short-circuit, and there is no sense of stiffness, which is the most uncomfortable point when using electric bedding, Gives a feeling.

Second, far infrared rays are radiated from the carbon heating element, which helps to activate human cells, can be embedded in the electric mat very simply, and leave no marks on the skin even after long-term use.

Third, electric bedding is lighter, maintenance costs are significantly reduced, there is no fear of overheating due to constant temperature heating. Table 1 summarizes electricity consumption and charges when applied to blankets and blankets, and Table 2 summarizes electricity consumption and charges when applied to electric mats.
