Description

Insulating electric heating wire {Electric Heating Device using Thermal Storage Heating Wire}

The present invention relates to an electric heating device mounted on an electric mat, electric heater, and the like,

More particularly, the present invention relates to a heat insulating electric heating device having a heat storage function, and a heat insulating electric heating device configured by connecting a power supply device with a thermostat for controlling an electric supply by using the heat insulating properties of the heat insulating electric heating wire.

In general, electric heating devices used for electric mats include a general electric heating wire coated with an insulator, etc., a mat made of a thick insulating material, etc. It consists of a power supply.

In addition, the electric heating device for electric heating mainly uses a heating element using nichrome wire, carbon or ceramic heater as the electric heating wire.

The heating device by the electric heating wire in the prior art as described above has a problem that the thermal insulation effect is significantly lowered due to the rapid rise to high temperature by the electric supply and to the normal temperature by the electrical cutoff, and the insulation coated general heating wire to a high temperature It may deteriorate and burn slowly, may cause short circuit problems, and is vulnerable to direct external shocks.

In addition, in general heating wire, the actual heating temperature is reduced by 20% by coating, and the heating wire is severely different due to bending or placing an external object.

In addition, in a general electric stove, the electric heating element generates light as well as heat, and thus is less efficient than the heating element generated by pure heat, and the lifetime of the heating element is shortened due to high overheating and may cause problems in safety.

The present invention has been invented to solve the above problems, by inserting an uncoated electric heating wire instead of the insulation-coated general electric heating wire into the insulating tube to form an air insulating layer to form an insulating electric heating wire, heat generation in the electric heating wire And a temperature control device for causing the heat to accumulate in the air insulating layer and controlling the electricity supply for the duration of the accumulated heat.

In addition, in order to further improve the thermal insulation characteristics of the thermal insulation electric wire is characterized in that the insulating insulating oil layer filled with insulating oil in the air insulating layer in the insulating tube.

In addition, the heating element of the thermal insulation electric wire is built in a mat or pipe, or arranged in close contact on the heat reflector or hot water tank to configure the thermal insulation electric heating device.

According to the present invention, the thermal insulation electric heating device having a heat storage function and a thermostating device controlling a power supply using a thermal insulation property of the thermal insulation electric heating wire and a power supply device are connected to each other to configure the thermal electric heating device, thereby reducing energy consumption. Contribute to improvement and energy savings.

In addition, the heating wire of the insulation electric heating wire is a spiral wire that does not directly insulate the outer shell and does not deteriorate the shell or cause heat loss due to the outer shell. And it's safer electrically.

In addition, the electric thermal insulation heating element generates pure heat without generating light to minimize energy consumption, and the lifespan of the heating wire is semi-permanent at a safe temperature around 200 ° C.

Hereinafter, the present invention will be described with reference to the accompanying drawings, FIGS. 1 to 6.

1A and 1B are perspective and sectional views of a general electric heating wire, and FIGS. 2A and 2B are a perspective view and a sectional view of an insulating electric heating wire to which the technique of the present invention is applied.

The general electric heating wire 10 is an insulating coating 11 by closely contacting the electric heating wire 12 with PVC or silicon, but the insulating electric heating wire 20 applied to the present invention uses the electric heating wire 12 as an insulating tube such as silicon or Teflon. Inserted into (22) to form an air insulating layer 21 in the insulating tube 22, the insulating coating is carried out.

3 is a circuit connection diagram of the thermal insulation electric heating apparatus of the present invention.

In the thermal insulation electric heating apparatus, the thermal insulation electrical heating wire 20 configured by inserting an uncoated electric heating wire 12 into the insulation tube 22 to form an air insulation layer 21 in the insulation tube 22 is provided. And the temperature control device 40 and the power supply device 50 to maintain the specified temperature by controlling the feeding time t1 and the disconnection time t2 by using the insulating property of the heating wire 20 and the insulating electric heating wire. I am doing it.

Temperature control device 40 is composed of a power saving switch 41 and the control circuit section 42, the control circuit section 42 detects the heat insulation electric heating wire and reaches the set rising point temperature (T21) power saving switch 41 ) Is maintained in the power cut mode, and the cycle of changing from the set falling point temperature T22 to the power feeding mode is repeated.

In this way, the detection of the rising point temperature T21 and the falling point temperature T22 of the thermal insulation electric heating wire 20 is performed by a duty rate set in advance by a temperature sensor or by a timer TIMER.

Figure 4 is a comparison of the thermal insulation properties of the thermal insulation electric wire to which the technique of the present invention is applied.

In the thermal insulation electric heating device of the present invention, the thermal insulation effect comparison chart by the presence or absence of insulating air layer and insulation oil injection. As shown in the figure, the temperature rises rapidly to a high temperature by feeding, and due to the temperature characteristic of rapidly descending to a normal temperature due to power failure, there is almost no thermal effect.

However, in the case of the thermal insulation electric heating wire 20, there is a thermal insulation effect due to the gentle power feeding temperature characteristics and the power dissipation temperature characteristics, such as the feeding characteristic diagram (C21) and the disconnection characteristic diagram (C22). In order to improve, it is possible to construct an insulating insulating oil layer filled with insulating oil in the air insulating layer 21 in the insulating tube 22.

In this way, the thermal insulation effect is best in the case of the insulation oil injection insulation electric heating wire 30 insulated with the insulating oil in the air insulation layer 21, the following is the case of the insulation electric heating wire 20 filled only with air and composed of only a simple heating wire In the case of the electric heating wire 10, there is almost no thermal effect.

5 is a case where the duty ratio is 50% as a temperature cycle characteristic of the thermal insulation electric wire to which the technique of the present invention is applied.

As shown in FIG. 5, the energy saving effect is largely set by the feeding time and the disconnection time to be kept warm.The smaller the duty ratio, which is the ratio of the feeding time t1 and the disconnection time t2, is, the higher the electric heating wire is. The gap between the point temperature T21 and the falling point temperature T22 is small, but the energy saving effect is reduced.

In addition, the temperature difference between the electric heating wire rising point and the falling point at the same duty rate is maximum in the general electric heating wire (10), the temperature difference is greatly reduced in the insulating electric heating wire (20), insulating oil injection insulating electric heating wire (30) In the case of the temperature difference is further reduced it can be seen that the warming effect is slightly better.

An average temperature T20 that is an average of the rising point temperature T21 and the falling point temperature T22 of the thermal insulation electric wire; and an average temperature that is an average of the rising point temperature T11 and the falling point temperature T12 of the general electric heating wire ( T10); and the thermal insulation effect in the thermal electric heating wire 20, and appears as an energy saving effect.
