Description

Electric Mat Using Accumulated Heating Material

The present invention relates to an electric mat using a heat storage material. More particularly, it relates to an electric mat that can prevent corrosion of a heating wire by installing it separately so that a heat storage material and a heating wire do not come into contact with each other, thereby preventing fire and electric leakage.

In general, an electric mat is a heating device using electricity, which is relatively inexpensive compared to expensive fuels such as oil and gas, since an electric heater line is arranged in a heating hose.

However, this conventional electric mat did not have other functions other than heating and heat transfer functions because the heating wire is simply built into the heating hose. In addition, since heat generation and heat maintenance of the heating wire depend only on power supply, there is a disadvantage in that power consumption is large to maintain the elevated temperature for a long time.

In order to solve this problem, a hemispherical tube with a groove formed in the center of the panel is formed up and down in the 'electric ondol panel', and a heating wire is inserted in the center of the hemispherical tube, and a heat conduction cover plate is mounted on the top.

However, since this electric ondol panel does not have a heat absorption tube like the conventional electric mat, the heat generated by the heating wire is transferred through the metal, so it has the advantage of a faster temperature rise than a liquid with a high specific heat, but maintains the elevated temperature In order to do this, there is a disadvantage of large power consumption because the heating state of the heating wire must be maintained continuously. Also, since the heating wire is inserted between the metal rods, if the coating of the heating wire is peeled off even a little, there is a problem of electric shock and short circuit.

In the 'electric boiler mat' to solve this problem, the electric mat is a plurality of angle boxes that are collapsible to each other, and each electric mat is made of a polyurethane insulating member, a heating wire and a heat storage material arranged on the insulating member. It consists of a built-in heating hose, a heat transfer plate disposed on the upper portion of the heat insulating member so as to be in contact with the heating hose, a plate-shaped mugwort pack disposed on the heat transfer plate, and a heat sink disposed on the mugwort pack; a temperature sensor installed in the heating hose to sense the temperature; A technology related to an electric boiler mat provided with a temperature controller installed in an area of the angle box to adjust the temperature of the heating hose according to the temperature value sensed by the temperature sensor has been disclosed.

However, since this 'electric boiler mat' supplies power after arranging a heating hose with a heating wire and heat storage material on the insulating member, if it comes into direct contact with the heat storage material, a fire or short circuit may occur if the heating wire is peeled off. This caused a safety problem, and there was a disadvantage in that the heat storage material leaked because the blocking caps sealing both ends of the heating hose fell out due to the expansion of the heat storage material.

An object of the present invention is to provide an electric mat that can completely prevent fire and electric leakage by completely preventing corrosion of the heating wire due to the heat storage material by separating the heating hose and the heating wire having the heat storage material embedded therein.

Another object of the present invention is to provide an electric mat that can be assembled by separating the heating hose installed on the heat insulating member into a straight part and a curved part.

Another object of the present invention is to provide an environmentally friendly heating appliance using silver fiber and loess that can prevent the growth of pathogens that occur during heating.

Another object of the present invention is to provide an electric mat having a controller that can accurately control the temperature of the electric mat and can be used safely.

The present invention is a heat insulating member (2) installed on the floor; a heating hose 11 filled with a heat storage material therein and disposed on the heat insulating member 2 in a zigzag manner; a heating wire 14 for heating the heating hose; a heat transfer plate (3) laminated on the heating hose; a silver fiber layer 4 laminated on the heat transfer plate 3; A controller for controlling the temperature of the electric mat (1) is composed of a loess cover layer (5) disposed on the silver fiber layer (4) and a finishing material (6) covering the upper portion of the ocher cover layer (5) (7) and; In the conventional electric mat having a connecting means (8) for coupling the electric mat (1) and the controller (7), the heating hose is an upper hose having concave portions (16, 16') formed in the central part of the longitudinal direction. (12) and a lower hose 13, a fastening groove 15 is formed on one side of the upper hose 12, and a fastening corresponding to the fastening groove 15 on one side of the lower hose 13. A sphere 17 is formed, and a heating wire 14 is inserted between the concave portions of the upper hose 12 and the lower hose 13, and then the fastening groove 15 and the fastener 17 are combined. , It is characterized in that both ends of the heating hose are sealed and closed with a blocking cap (18).

As described above, since the electric mat of the present invention is installed indirectly so that the heating hose having the heat storage material and the heating wire do not come into contact with each other, corrosion of the heating wire due to the heat storage material can be completely prevented, thereby preventing fire and short circuit. .

By using the antibacterial and anti-toxic properties of the heating hose filled with heat storage material and the silver fiber layer, various pathogens in the room can be removed and the surrounding environment can be kept clean. Since the heat storage material emits far-infrared rays, it is beneficial to the human body, and the power consumption is very low compared to other heating devices, so it has the advantage of reducing energy consumption.

In addition, since the heating hose can be assembled by separating it into a straight part and a curved part, the length of the electric mat can be adjusted, and construction is very easy.

It is preferable to use a heat storage material prepared by dissolving salt in water as the heat storage material, and this heat storage material is made to contain 70% to 90% salt solution. Since this heat storage material contains calcium chloride (CaCl2), which has excellent heat storage properties, it is excellent in temperature rise and maintenance of elevated temperature.

The composition ratio of the heat storage material used in the best embodiment in the present invention is salt (NaCl) 60 to 70% by weight, water (H2O) 20 to 30% by weight, sodium hydroxide (NaOH) 5% by weight and acetic acid (CH3COOH) 5 % by weight of the mixture. Here, sodium hydroxide and acetic acid may be optionally used as needed.

Here, since the heat storage material used as the heat storage material contains a calcium chloride component having excellent heat storage properties, it is possible to maintain the elevated temperature for a long time with relatively little electrical energy, and thus the heating effect is excellent. In addition, since far-infrared rays are generated from the heat storage material, there is an effect of activating blood circulation.

The heat transfer plate 3 is made of a metal plate material such as a copper plate having excellent thermal conductivity. The heat transfer plate 3 receives heat from the upper hose 12 .

The silver fiber layer 4 is manufactured to have a rectangular shape through predetermined processing of a fiber containing silver powder. Since the silver fiber layer 4 is attached to the top of the heat transfer plate 3 , it has the effect of preventing the growth of bacteria in the electric mat 1 and removing odors. In order to obtain such odor removal and sterilization effects, other types of substances or packs using mugwort or herbal medicines may be used instead of the silver fiber layer.

The loess cover layer 5 is manufactured by adsorbing loess to fibers containing cotton or hemp and cutting it to fit the size of the mat. The loess cover layer 5 has an effect of emitting far-infrared rays contained in a large amount in the loess while being attached to the upper portion of the silver fiber layer 4 .

The electric mat (1) is completed by forming the finishing material (6) on the upper portion of the loess cover layer (5). On the other hand, the temperature sensor 9 is installed in the heating hose 11, as shown in Figure 6c, is connected to the input terminal of the controller (7). That is, the connecting wire of the temperature sensor 9 passes through the perforation of the blocking cap 18 and is connected to the input terminal of the controller 7 .

The output terminal of the controller 7 is connected to the power supply 28 , and the input terminal is connected by a connection means 8 connected to the heating wire 14 built in the heating hose 11 .

With this configuration, when power is supplied to the electric mat 1 according to the present invention to the heating wire 14 built in the space formed in the heating hose 11, the heating wire 14 generates heat to heat the heating hose 11. and the temperature of the heat storage material filled in the heating hose rises. Then, as the temperature of the heat storage material rises, heat is conducted to the heat transfer plate 3, and heat is sequentially heated to the outside through the silver fiber layer 4, the ocher cover layer 5 and the finishing material 6 disposed on the heat transfer plate 3 Heating is achieved by this transmission.

Switching means (S1 to S3) for switching AC power, DC power, or blast-rectified power to the power supply 28 is connected to another output terminal of the controller 7 . As the switching means, an element such as a relay having a contact point or a non-contact semiconductor active element such as a TRIAC or an SCR is used. Preferably, if TRIAC or SCR is used, noise generation or spark generation can be prevented, and the lifespan of the device can be extended and the response speed can be increased.

If the user sets the heating temperature by operating the temperature setter 26 of the controller 7, the reference temperature voltage (or current) value is input to the controller 7, and the temperature of the room detected by the indoor temperature sensor 10 is The current temperature voltage (or current) value is input to the controller 7 and compared with the reference temperature voltage (or current). When the temperature value input from the room temperature sensor 10 is less than the set temperature range value, the controller 7 outputs a switching signal, so the switch is turned on and electricity is supplied to the heating wire 14 .

Therefore, since the heating wire 14 is heated, the temperature of the heat storage material rises, and the rising heat is in the order of the heating hose 11 and the heat transfer plate 3, the silver fiber layer 4, the ocher cover layer 5 and the finishing material 6). As it conducts to the heat, the room is heated to the set temperature.

On the other hand, when the indoor temperature value detected by the indoor temperature sensor 10 exceeds the set reference temperature range, the switching signal is not output to the output unit of the controller 7, so the switch is turned off, and the Since the supplied electricity is cut off and the heating of the heating wire 14 is stopped, the temperature of the heat storage material is lowered.

Accordingly, the indoor temperature cannot exceed the set temperature, and since the power supplied to the heating wire 14 is controlled by repeating the above process, heating is performed at the desired temperature set by the user. The room temperature, the temperature in the heat storage material, and the temperature value of the setting unit are displayed on the LCD display 22 as digital numbers.

It is preferable that the allowable deviation of the reference temperature allowed by the controller 7 is in the range of ±1°C to ±3°C so that the heating wire 14 does not react (operate) sensitively. If the temperature input from the indoor temperature sensor 10 is less than the allowable deviation range, power is automatically supplied to the heating wire 14 .
