The secondary temperature sensing device 320 or the primary temperature sensing device 340 coupled to the ceramic fiber mat plate 220 to cut off the power supply to the power supply unit 160 when the heating element 200 is overheated above the set temperature. Overheat prevention member 300 consisting of;

It is formed in the upper cover 120 and the lower cover 140 of the main body 100, the non-insulating material 400 is formed to cover the heating element 200; is configured to include.

The main body 100 has a concave upper cover 120 and a lower cover 140 are symmetrically coupled to have a receiving portion therein, and the packing 180 is coupled to the joint to be sealed.

The power supply unit 160 is formed on the upper cover 120 or the lower cover 140 so that an external power source can be connected.

In addition, a lamp 190 for visually displaying the power supply is provided on one side of the power supply unit 160 .

The body 100 is preferably circular, but may be variously configured in polygons such as ovals, triangles, or squares.

The material of the body 100 also does not need to be set to any one, and resin, thermosetting resin, metal, light metal, loess, ceramic, etc. may be used, and if necessary, silver or fine ceramic on the outside of the body 100, A decoration including jade, etc. may be further added to suppress harmful bacteria that may be parasitic on the outside of the body 100 .

The heating element 200 includes a ceramic fiber mat plate 220 and a heating coil 240 coupled to the inside of the ceramic fiber mat plate 220 .

The ceramic fiber mat plate 220 is preferably in the shape of a disk, and is vertically separated and consists of an upper first plate 221 and a lower second plate 222 .

The ceramic fiber mat plate 220 is made of a non-combustible ceramic fiber (wool, cotton) mat.

The thickness of the ceramic fiber mat is continuously pressed on a rotating roller line to adjust the thickness, and then cut to a predetermined size.

According to an example, the width is 14,640mm, 7,200mm, and 3,600mm, and the length is 1,220mm, 610mm, and 650mm in size, and the ceramic fiber mat plate 220 is manufactured.

The density of ceramic fibers is manufactured by compression to become 96 kg/cm³, 128 kg/cm³, and 160 kg/cm³.

Ceramic fiber mats are manufactured in thicknesses of 6m/m, 10m/m, 20m/m, 25m/m, 30m/m, and 50mm.

The prepared non-combustible and insulating ceramic fiber mat plate was cut into a circular, rectangular, pentagonal, oval, etc. according to the internal size of the thermal storage type electric steamer, pressed with a pressure cutter, and cut into upper and lower plates to cut non-combustible and insulated ceramic fiber plates Manufactured by cutting with a dedicated cutting knife.

A first plate and a second plate made of heating ceramic ceramic are bonded between the upper and lower layers of the non-combustible and insulating ceramic fiber.

In the first plate 221 or the second plate 222, a coil-shaped heater is inserted into the groove and fixed with a bolt and a nut between the upper and lower plates.

The first plate 221 or the second plate 222 has a plurality of circumferential grooves 224 formed therein, and a heating coil 240 is embedded in the grooves 224 .

The heating coil 240 generates heat when power is applied, and is connected to the power supply unit 160 to control ON/OFF.

When power is applied to the heating coil 240, it is heated to 1000° C. in about 5 to 6 minutes and the temperature rises. When the power is turned off in this state, the temperature can be maintained for about 3 to 4 hours.

Meanwhile, an overheat prevention member 300 is formed on the ceramic fiber mat plate 220 to prevent overheating.

The overheat prevention member 300 includes a primary temperature sensing device 340 for sensing the temperature of the power supply wire and the ceramic fiber mat plate 220 in which the heating ceramic hot plate is kept constant.

The primary temperature sensing device 340 may be a bimetal (automatic return type) or a bimetal (non-automatic return type).

As shown in Figure 8, the primary temperature sensing device 340,

It is mounted on the heat transfer bracket connected to the ceramic fiber mat plate 220, is connected to the electric wire of the socket 5, and the bimetal 346 is formed therein,

When the internal temperature of the ceramic fiber mat plate 220 rises abnormally, the bimetal 346 is bent and the connection state between the contacts is short-circuited so that the current is cut off to prevent overheating.

The primary temperature sensing device 340 includes a bimetal 346 to automatically cut off power when overheating, and preferably operates only at 50° C. to 120° C. or less.

The primary temperature sensing device 340 is an automatic return type or a non-automatic return type.

The non-automatic return type is provided with a return button 347 to resume normal operation after power-off operation, and when the return button 347 is pressed, the bimetal 346 is pressurized to manually return to the original state so that the connection between the contacts can be maintained. It is a temperature sensing device for additional safety.

The primary temperature sensing device 340 is an automatic return type and has a closed type structure.

In this case, the thermal storage type electric steamer may be a general operation type that operates again when the temperature is lowered again, but the PTC temperature rises in the primary temperature sensing device 340 or the secondary temperature sensing device 320 to further improve safety performance. The device (3) can be mounted.

Therefore, the PTC method of power supply after one operation is a function of maintaining the open state by the PTC heater until the power is removed when the power supply is activated under overheat or overcurrent conditions. It includes the ability to remove power for a sufficient amount of time to allow it.

Meanwhile, a secondary temperature sensing device 320 may be further included.

The secondary temperature sensing device 320 causes an abnormal state in which the primary temperature sensing device malfunctions and continues to operate. At this time, the secondary temperature sensing device 320 operates to cut off the safe power supply.

The secondary temperature sensing device 320 is a bimetal (non-automatic return type).

Preferably, the secondary temperature sensing device 320 is set to be 30°C higher than the primary temperature sensing device.

In this case, the secondary temperature sensing device 320 is a non-automatic return type that is additionally installed by the safety device.

The secondary temperature sensing device 320 has a push button device for manually returning it.

The secondary temperature sensing device 320 includes a PTC temperature boosting device 3 .

9 to 11, the PTC temperature boosting device 3 is

a lower body 31 having side walls and a bottom surface formed therein to form a space;

a PTC element (36) inserted into the lower body (31);

a base plate (32) inserted into the lower body (31) and seated on the upper surface of the PTC device (36), the first connection terminal (321) formed;

a cover 33 coupled to an upper portion of the base plate 32 and a bimetal 34 seated on the upper portion of the cover 33;

It is coupled to the upper portion of the lower body 31 and is coupled to the outer surface of the cover 33 to accommodate the bimetal 34 and the case 35 in which the second connection terminal 352 is formed.

A first terminal 341 is formed on the bimetal 34 , and a second terminal 325 is formed on the base plate 32 .

When the first terminal 341 and the second terminal 325 are in contact, a current flows, and when the first terminal 341 and the second terminal 325 are spaced apart, the current is cut off.

Therefore, when the PTC element 36 is excessively heated, the bimetal 34 is deformed, so that the first terminal 341 and the second terminal 325 are separated and separated, thereby cutting off power.

In addition, to each of the first connection terminal 321 of the base plate 32 and the second connection terminal 352 of the case 35, a positive conductor or a negative conductor of an external electric wire is respectively connected to the bimetal 34 and the PTC element 36. ) to be powered on.

The cover 33 is inserted between the base plate 32 and the case 35 to prevent a short circuit accident by preventing the direct contact between the base plate 32 and the case 35 through which anode current and cathode current flow, respectively. can be prevented in

On the other hand, the PTC element 36 is heated by the application of power, and when the temperature is excessively high, the bimetal 34 is operated to cut off the power.

That is, as the bimetal 34 is bent, the first terminal 341 is spaced apart from the second terminal 325 of the base plate 32 to cut off the power.

Thereafter, when the PTC element 36 is cooled, the bimetal 34 is manually restored to enable reuse.

Meanwhile, the power supply unit 160 is configured to include an inlet 162 coupled to the body 100 and a plug 165 coupled to the inlet 162 to supply power. The plug 165 may be formed for 10A, 250V~, low temperature for type 1 equipment.

When using the inlet 162 for the 10A, 250V high-temperature appliance connector inlet (Inlet Appliance InIet) for class 1 equipment, the pin temperature is 60 ~ 120 ° C. As shown in the figure, the shape is for class 1 equipment As a connector inlet for 10A, 250V high-temperature equipment, it has a structure having three pins 1621 and a U-shaped protrusion with a size of 4.5±0.3mm inside so that it can be seen that it is for high-temperature use.

Correspondingly, the plug 165 has a size of 5±0.3 mm on the insertion surface where the concave inlet is formed so that the three pins 1621 can be inserted in the center of the straight surface of the upper surface so that it can be seen that the plug 165 is for high temperature use of 10A and 250V for class 1 equipment. A U-shaped groove is formed.

Accordingly, the protrusion formed in the central portion of the inlet 162 may be properly coupled to the groove of the plug 165 .

In addition, a wedge-shaped fitting portion 1624 is formed on the outer side surface of the inlet 162 . When viewed from the side, the fitting portion 1624 has an inclined surface toward the lower portion and a right-angled surface formed on the upper portion to have an isosceles triangle shape.

Therefore, when the inlet 162 is inserted into the coupling hole formed in the upper cover 120, the fitting portion 1624 is inserted from the inclined surface, and then the upper right-angled surface can be in close contact with the periphery of the coupling hole of the upper cover 120, so that it does not fall out. will not

In addition, the socket 5 is inserted into the inner side of the upper cover 120 so that the inlet 162 is coupled and supported by the ceramic fiber mat plate 220 is included.

The socket 5 is opened up and down so that an inlet coupling part 52 to which the inlet 162 is coupled is formed on one side, and a slot 54 to which the primary temperature sensing device 340 is coupled is formed on the other side.

Therefore, the heat transfer bracket to which the primary temperature sensing device 340 is coupled is inserted into the slot 54 and coupled, and the socket 5 is supported in contact with the ceramic fiber mat plate 220 so that the heating element 200 does not move. It provides stability.

On the other hand, in the non-insulating material 400, the particle size of the mineral material powder is 2-5 μm, and the density is 0.28 g/cm 3 .

Mineral material is aluminum oxide (Al₂O₃): 60~70wt%, silicon dioxide (SiO₂): 20~30wt%, iron oxide (Fe₂O₃) + sodium oxide (Na₂O) + potassium oxide (K₂O) mixture: 0.2wt%~1.2wt% The combination of the above is melt-spun in a stream mechanical disperser at 2,000℃ or higher in an electric furnace other than heating and blown with a spray (air) into ceramic fibers (wool, cotton).

A mixture of iron oxide (Fe₂O₃) + sodium oxide (Na₂O) + potassium oxide (K₂O) dissolves in water or generates an oxidized form, which causes corrosion of surrounding metal materials and causes malfunctions (eg, corrosion of heating wires). Therefore, it is used in a minimal amount.

The thickness of the ceramic fiber, which is the non-insulating material 400 formed in this way, is adjusted by continuously pressing the ceramic fiber mat with pressure in a rotating roller line to manufacture a flat plate.

Specifically, aluminum oxide (Al₂O₃): 46.2 wt%, silicon dioxide (SiO₂): 53.2 wt%, iron oxide (Fe₂O₃) + sodium oxide (Na₂O) + potassium oxide (K₂O) mixture: 0.6 wt% of combination or oxidation A combination of aluminum (Al₂O₃) 52.3%, silicon dioxide (SiO₂) 47.6%, iron oxide (Fe₂O₃) + sodium oxide (Na₂O) + potassium oxide (K₂O) mixture 0.1 is sprayed by melt spinning in a stream mechanical disperser in a non-electric furnace It is made of ceramic fibers (wool, cotton) by blowing with (air).

For safety temperature sensing, it has a fixed iron plate structure that fixes parts for temperature sensing in which the temperature sensing device operates constantly on the central axis fixed to the central part of the internal ceramic heater plate.

Therefore, when power is applied to the heating coil 240, in about 5 to 6 minutes, it is heated to 1000° C. Because it is in a high temperature state, there is a risk of burns if it comes in contact with the skin.

When the power is turned off, the temperature can be maintained for about 3 to 4 hours.

Thereafter, the temperature is lowered by the non-insulating material 400 surrounding the ceramic fiber mat plate 220 , so that it can be lowered to a temperature suitable for use in the human body.

In addition, it is possible to prevent skin burns when used in a safety fiber bag (6) or an abdominal band (8) to be described later.

Therefore, since the lid 68 can be opened and closed, it is opened when power is supplied, and when closed after disconnecting the power line, it has a function of attaching a Velcro tape to fix it.

On the other hand, the aforementioned safety fiber bags (6, 6') may be completed by pulverizing dried mugwort, putting it in a cotton cloth, and sewing it.

That is, the safety fiber bags 6 and 6' are provided with a storage bag (not shown) therein, and a mugwort pad (not shown) used in the storage bag may be further included.

Referring to FIG. 6 , the bellyband 8 for holding the main body 100 of the thermal storage type electric steamer is included.

The belly band 8 may be conveniently movable when used on the waist or stomach.
