The present invention relates to a heat generating device using an arc generator.

Visible light treatment is a treatment that treats diseases by irradiating natural or artificial light to a part of the body. , is known to have a wide range of therapeutic effects, such as the treatment of skin cancer. When light of an appropriate wavelength and intensity is selected and irradiated according to the nature of the disease, photons are transmitted or absorbed through the skin to activate the metabolic function of the body, thereby treating the disease. As a device for irradiating visible light, a device for outputting visible light using a light source such as LED has been proposed, but there is a difference from the actual wavelength of sunlight, and the amount of light is too small, so there is a problem that the treatment effect is not great. .

Therefore, a device for outputting visible light using an arc is being developed, but in the case of a conventional arc generating device, the generation of uniform visible light is not achieved by using the AC power received from the outside and applying it to two arc rods as it is. It is difficult, and a dangerous situation may occur during careless handling due to high current and high temperature.

On the other hand, there is a problem in that the high-temperature heat generated when such an arc generating device generates an arc and outputs visible light is simply discharged and wasted.

For example, the power conversion unit, as shown in FIG. 1 , a ball-screw (Ball-Screw) type power conversion structure using screw bars 63 and 64, or a rack-pinion (Rack-Pinion) ) can be formed in a power conversion structure using

As a result, when the first motor 11 and the second motor 12 are driven, the first moving member 21 and the second moving member 22 perform a linear motion, thereby causing the first holder 51 and The first arc rod 30 and the second arc rod 40 accommodated in the second holder 52, respectively, also move together. In particular, when the first arc rod 30 and the second arc rod 40 are spaced apart by a preset distance after contact by the movement of the first arc rod 30 and the second arc rod 40, the first arc An arc is generated by the potential difference between the rod 30 and the second arc rod 40 .

Meanwhile, the first arc rod 30 and the second arc rod 40 described above may be preferably made of carbon or tungsten, which is a conductive material.

2 is a diagram schematically illustrating the configuration of a heat generating device using an arc generator according to an embodiment of the present invention, FIG. 3 is a diagram schematically illustrating the configuration of a power supply unit, and FIG. 4 is an embodiment of a sensor unit is a diagram showing Hereinafter, a heat generating apparatus using an arc generator according to an embodiment of the present invention will be described with reference to the above-described arc generator and FIGS. 2 to 4 .

In the conventional visible light irradiation apparatus using an arc, by directly connecting one side and the other side of the AC power supplied from the outside with two arc rods, respectively, the amount of visible light generated by the arc was not constant, but the embodiment of the present invention and Likewise, when AC power is converted into DC power and power is applied to the arc rod, the amount of visible light generated by the arc can be kept constant.

The electrode conversion unit 120 is configured to apply the DC power transmitted from the power conversion unit 110 to the first arc rod 30 and the second arc rod 40, respectively, the first arc rod 30 and the second The polarity of the power applied to each arc rod is changed periodically with each other.

When the positive and negative terminals of the DC power output from the power conversion unit 110 are directly connected to the first arc rod 30 and the second arc rod 40, respectively, the first arc rod 30 is There is a problem of burning faster than the second arc rod 40 . In order to solve this problem, in the embodiment of the present invention, the polarity of the power applied to the first arc rod 30 and the second arc rod is periodically changed to each other by using the electrode conversion unit 120 .

Similarly, the second light receiving unit also cannot sense the laser c generated from the second laser light source 352 by the second arc rod 40 . That is, by grasping the moment when the first light receiving unit and the second light receiving unit do not detect the first laser (b) and the second laser (c), respectively, the end of the first arc rod 30 and the second arc rod 40 The position of the end of the can be detected.

When the arc generator 10 is in operation, an arc is generated by the first arc rod 30 and the second arc rod 40, thereby generating high-temperature heat inside the arc generator, and also the first A high voltage is applied between the arc rod 30 and the second arc rod 40, thereby generating a high current. In this case, when the user opens the door of the housing 80 , an accident may occur due to exposure to high temperature heat and high current or high voltage. In order to prevent such an accident from occurring, the control unit 400 may control the power supply unit 100 according to the door opening/closing detection of the first sensor.

Next, when the inclination of the housing 80 is detected by the second sensor, the control unit 400 controls the power supply unit 100 to cut off the power supply to the first arc rod 30 and the second arc rod 40 . can control

When the arc generator 10 is in operation, there is a risk factor of high heat and high current or high voltage, and the arc generator 10 may be tilted or collapsed due to an external impact, and an accident may occur. To prevent this, the control unit 400 may control the power supply unit 100 according to whether the second sensor detects an inclination.

Next, when it is sensed by the third sensor that the arc rods 30 and 40 are not seated on any one of the first holder 51 and the second holder 52 , the control unit 400 controls the first arc rod The power supply unit 100 can be controlled so that the power supply to the 30 and the second arc rod 40 is cut off, and furthermore, the first motor 11 and the second motor 12 of the arc generator 10 are driven can stop

Next, the control unit 400 limits the movement of the first holder 51 and the second holder 52 using the movement distances of the first holder 51 and the second holder 52 detected by the fourth sensor. It is determined whether the region has been reached, and when the first holder 51 and the second holder 52 reach the movement limiting region, the first motor 11 and the second motor 12 of the arc generator 10 are may stop running. Through this, unnecessary power consumption and damage to the first motor 11 and the second motor 12 may be prevented.

Next, when the positions of the ends of the first arc rod 30 and the second arc rod 40 are detected by the fifth sensor, the controller 400 controls the first motor 11 and the second motor 12 . It is possible to control the distance between the first arc rod 30 and the second arc rod 40 to be kept constant by stopping the driving of the .
