Electric stove combined electric heater according to a preferred embodiment of the present invention, which can perform the role of the electric stove and the role of the hot air heater at the same time, the main body 10, the duct 20, the ceramic heating element 30, It comprises a partial reflector 40 and a warm air inducing means.

Here, the main body 10 is a low voltage transformer 53 connected to the control unit 50 is installed in the lower storage space (B), the heat generating space (A) is formed in which the entire reflector 60 is formed in the center The hot air discharge opening 11 is formed in the upper part.

In addition, the hot air discharge port 11 is provided with a horizontal louver 12 (louver) to adjust the direction and the degree of dispersion or the discharge amount of the hot air discharged in the room, and the inlet ( 13) is formed.

In addition, the control unit 50 is provided outside the main body 10 is composed of a liquid crystal window 51 and a switch 52 to display the state of the stove.

Therefore, the power supplied from the outside is reduced by the voltage through the low voltage transformer 53 connected to the controller 50, the power consumption is reduced, only in the heat generating space (A) of the main body 10 by the reduced power The surface temperature of the ceramic heating element 30 installed can be raised to 1,500 to 2,000 ° C., and a sensor (not shown) is installed near the ceramic heating element 30 to control the ceramic heating element 30. When the temperature rises above a predetermined temperature, the supply of power to the ceramic heating element 30 is temporarily blocked to prevent fire.

In addition, by forming a plurality of suction ports 13 on the front or side of the main body 10 to draw the outside air by the operation of the blower 14 to protect various devices.

In addition, the duct 20 is formed between the storage space B of the main body 10 and the hot air discharge port 11 of the main body 10, and a blower 14 is provided therein, The air warmed by the ceramic heating element 30 may be directly or indirectly supplied to the room from the duct 20 formed to communicate with the storage space B of the main body 10.

In addition, the ceramic heating element 30 is installed in the heating space A and receives light from the low voltage transformer 53 to emit light and generate heat at a high temperature.

In addition, the ceramic heating element 30 may be a ceramic material (MoSi ₂ ) having an ohmic value of 5 or less supported by the pedestal 31 installed in the partial reflector 40.

Here, the ceramic heating element 30 is made of MoSi ₂ as the main material, metallurgical (Ingot) at a high temperature of 2,800 ° C. or higher, and having a characteristic of a semiconductor. Thermal durability (1,500 ° C. to 2500 ° C.) for generating high temperature Can satisfy

In addition, the internal resistance of the ceramic heating element 30 is variable depending on the surface temperature, the higher the surface temperature, the higher the internal resistance, the surface temperature is rapidly increased even a small power change due to the increased internal resistance above a certain temperature. .

Due to this characteristic, it is more preferable to use a low voltage transformer 53 for applying a low voltage and a high current, rather than applying a high voltage to the ceramic heating element 30.

Here, the low-voltage transformer 53 is made of a core material of high quality silicon steel sheet (0.2 ~ 0.3t), after perforating in a ring shape and surface treatment, and then dozens of sheets overlap the second surface treatment, and then calculate the current capacity By winding and insulated with the necessary copper wire thickness, the secondary winding can also be configured to be sensitive to changes in current rather than changes in voltage in the same way.

For reference, Table 1 shows the internal resistance change of the heating element, and Table 2 shows the electrical characteristics of the heating element.

[Table 1] Change in internal resistance of heating element (D: 6mm, L: 300mm)

Heating element temperature (℃) Heating element internal resistance (Ω) 1,200 0.03 1,400 0.04 1,600 0.05 1,800 0.07 2,000 0.08

[Table 2] Electrical characteristics of the heating element (D: 6mm, L: 300mm)

Heating element temperature (℃) Supply current (A) Supply voltage (V) Power Consumption (W) 1.200 223.5 6.6 1.475 1.400 226.0 " 1.491 1.600 228.5 " 1.508 1.800 231.0 " 1.524 2.000 233.5 " 1.541 2.200 235.0 " 1.551

Therefore, the ceramic heating element 30 of the present invention is capable of generating heat up to about 2,500 ° C. even when the same electric power as that of the ordinary heating element is supplied.

In addition, the partial reflector 40 has a shape surrounding the rear of the ceramic heating element 30 to reflect the light emitted from the ceramic heating element 30 to the room.

Here, the partial reflector 40 is a semi-cylindrical shape, the total reflector 60 or the partial reflector 40 is formed of a thin stainless steel to increase the reflectance when the ceramic heating element 30 is heated while the duct 20 Allow the air inside to heat up indirectly.

In addition, a heat collecting portion 70 is installed on the front surface of the total reflector 60 or the partial reflector 40, wherein the heat collecting portion 70 forms a heating wire on a ceramic rod that emits far infrared rays, or uses a radiator core. It is preferable to form so as to absorb the heat generated from the ceramic heating element to collect.

In addition, the warm air induction means may be applied to various types of warm air induction apparatus for inducing high temperature warm air generated in the ceramic heating element 30 to the duct 20, preferably, inside or outside the heating space And a perforated surface 90 formed in an upper side of the bellows 100, which is in communication with the blower fan 80 and the partial reflector 40, which is installed to the duct 20 in a winding manner to introduce air into the heat generating space. It is a configuration made.

Here, the perforated surface 90 is not necessarily formed at the upper end of the bellows 100, and instead of the bellows 100, a plurality of ceramic heating elements 30 are disposed in the heat generating space, and the heat generating space is provided. In (A), the warmed air may rise due to the air convection of the blower fan 80 and may be discharged through the perforated surface (not shown) formed on the upper surface of the heat generating space (A).

The electric stove combined heater of the present invention is configured as described above, when the user "on" the switch 52 to supply power to the ceramic heating element 30 through the control unit 50.

When power is supplied to the ceramic heating element 30 as described above, the ceramic heating element 30 generates heat to a set temperature, and the heat collected by the heat collecting part 70 and the partial reflector 40 is collected into the room. The air in the duct 20 is indirectly heated at the same time as it is supplied directly. Then, as the air in the duct 20 rises, the controller 50 rotates the blower 14 so that the air in the duct 20 is increased. It is supplied to the room through the hot air discharge port 11 is installed horizontal louver (12).

At this time, the air inside the heat generating space (A) by the blower fan 80 rises along the bellows (100) and is discharged to the perforated surface (90) formed on the upper surface of the bellows (100), the warm air is The air is mixed with the air discharged through the duct 20 to maximize the hot air effect.

Therefore, the electric heater combined hot air heater of the present invention configured as described above can directly and indirectly heat the indoor air quickly and cleanly.

In addition, by cooling the heat applied to the electronic devices installed in the storage space (B) of the main body 10 by the blower 14, it is possible to protect the electronic device.

That is, as the blower 14 rotates, cold air of the room enters through the inlet 13 of the main body 10, and the cold air passes through the duct 20 through the electronic device to the room. I will go out again.
