Description

Heating device {HEATING APPARATUS}

The present invention relates to a heating device for heating air using a heating wire, and more particularly, to a heating device for a dry sauna booth that improves heating efficiency and safety and reduces fire risk.

In general, saunas facilitate metabolism of the human body and relieve fatigue by promoting blood circulation and skin respiration by discharging waste products accumulated in the body through sweat through high-temperature heat (dry) or steam (wet). It has several effects, such as relaxing stiff muscles.

In particular, it has been reported that high-temperature heat therapy using the far-infrared radiation wavelength band as a heat source is effective in treating chronic diseases such as hypertension, congestive heart failure, or rheumatoid arthritis.

However, in most dry saunas, an electric heater or heating element that converts electric energy into thermal energy is installed inside, and the air is directly heated using this method. , due to excessively high power consumption, there is a problem in that energy efficiency is considerably lowered.

In addition, when the heating element is made of a heating wire, the wiring state is easily disturbed by an external force or the like, so that the adjacent heating wire is tangled or stuck to each other, so there is a safety problem with a very high risk of a short circuit.

Meanwhile, a booth-type dry sauna apparatus capable of enjoying a sauna within a range of 40 to 80° C. using a ceramic heater emitting a large amount of far-infrared rays has been proposed.

For example, Patent Document 1 discloses an indoor dry sauna in which the air inside the sauna booth is heated according to the heat generated by the heat source generating unit and flows naturally by the convection phenomenon, thereby reducing operating costs and generating no noise.

However, this has a problem in that the thermal efficiency is somewhat lowered due to the structural nature of heat transfer due to heat conduction within the structure of the heat source generating unit, and the surrounding structure is deteriorated or deformed due to the heat of the heating wire.

You can adjust the settings, heating temperature and time, and control the power supply.

In addition, the controller detects when the heat emitted from the heating device 300 is overheated above a certain temperature, and sets the operation and heating temperature of the bimetal and heating device 300 to cut off the power supplied to the heating device 300 . According to the temperature sensor and control signal, the temperature value is converted and displayed digitally by the A/D converter, or when the power is supplied or cut off, or when the heating device 300 is above the set temperature, or electrically connected by the temperature sensor. A lamp and a display unit may be provided to respectively display this depending on the situation, such as when this is blocked or when heating is completed.

The heating device 300 includes a heating wire 310 , a stand 320 , and a heat shield 330 in order to increase heating efficiency and safety when generating heat by converting electrical energy into thermal energy and to lower the risk of fire.

That is, the heating device 300 serves to heat the user's body by heating when power is supplied. The wiring is made so that the distribution of the heat generation temperature is uniform.

The heating wire 310 is electrically connected to the controller 120 to dissipate heat when power is supplied and to adjust the temperature to a user's desired temperature.

Here, the heating wire 310 is coated with an insulating material in which silica and germanium are mixed in a certain ratio with a carbon wire or a super-precision alloy wire containing copper as a main component, so that the emissivity of far-infrared rays and anions and sterilization can be increased.

For example, the heating wire 310 is silicon dioxide (SiO ₂ ) 30 mole % and sodium oxide (Na ₂ O) 10 to 65 mole % and germanium (GeO ₂ ) 10 to 60 mole in an ultra-precision alloy wire containing copper as a main component. % can be formed by coating the germanium-based compound.

In addition, the heating wire 310 may employ a so-called magnetic field-free heating wire in which a magnetic field is canceled when an electric current flows and the generation of electromagnetic waves is small.

The stand 320 maintains the heating wire 310 spirally wound around it to prevent a short circuit due to deformation or contact due to external impact and heat of the heating wire 310 .

That is, when the spirally wound heating wire 310 approaches in a bent state, a short circuit may occur due to deformation or short circuit as the temperature rises. 310) and functions to keep the distance between them uniformly apart.

And the stand 320 includes an upper holder 321 , a low holder 324 , and a pair of legs 327 .

In the upper holder 321 , a plurality of first rims 322 are formed at regular intervals along the longitudinal direction on both sides of the upper holder 321 so as not to deviate from the state in which the heating wire 310 is wound and hung around it.

And, inside the upper holder 321, there is a first vent hole 323 that passes up and down for smooth circulation of air and heat.

The row holder 324 is arranged at regular intervals below the upper holder 321, and the heating wire 310 is wound around the perimeter so as not to deviate from the arranged state, the second at regular intervals along the longitudinal direction on both sides. A plurality of rims 325 are formed.

In addition, a second vent hole 326 passing up and down is perforated inside the row holder 324 for smooth circulation of air and heat.

The legs 327 are formed at both left and right ends of the stand 320 to maintain a constant height in a state in which the upper holder 321 and the low holder 324 are placed on the floor.

That is, the upper holder 321 and the row holder 324 are stably installed at regular intervals up and down by the bracket 328 having a constant height and supporting force, and the leg 327 is a row under the bracket 328 . It is formed integrally with the holder 324 .

Here, the stand 320, the legs 327, and the bracket 328 are preferably formed of a galvalume iron plate plated by mixing aluminum and zinc with excellent corrosion resistance and heat resistance.

In addition, heat resistance, etc. can be reinforced by coating the surface of the stand 320 with a ceramic coating method such as by melting the molten component with an oxygen acetylene flame using a special melt spraying device and spraying it on the metal surface with compressed air.

The heat shield 330 is mounted around the stand 320 to block heat transfer through direct contact between the heating wire 310 and the stand 320 .

That is, the heat shield 330 may prevent the heating wire 310 from directly contacting the stand 320 from heat conduction, thereby increasing heating efficiency and safety.

Here, it is preferable that the heat shield 330 is made of a silicone tube having a hollow cross-section and is wound in a zigzag shape between the first and second rims 322 and 325 and stacked in two stages.

The heat generating device 300 according to the embodiment of the present invention configured as described above maintains a uniformly spaced distance between the heating wires 310 to increase heat efficiency and safety, to reduce the risk of fire, and to even out the surrounding heat. It can be dispersed and cycled quickly.

In addition, as heat is evenly dissipated from the entire heat generating device 300 , heat conduction is fast and thermal efficiency is high, thereby obtaining a power saving effect of reducing power consumption.

In addition, since the heat shield 330 is double interposed between the heating wire 310 and the stand 320 to naturally block direct contact with each other, the heating efficiency and safety of the heating wire 310 can be increased as well as the stand. Structural safety deterioration due to deterioration or deformation of the 320 can be prevented.
