In general, the foot bath is soaked in the hot water around 42 ~ 43 ℃ to the area under the ankle of the ankle to perform about 20 to 30 minutes is effective in recovering fatigue.

And each bath is by dipping the lower part of the knee in hot water of 42-43 degrees to promote blood circulation of the feet and legs to facilitate metabolism and to recover from fatigue.

Thus, foot baths, foot baths and half body baths keep the upper body cool and the lower body warm, eliminating the cold that causes blood circulation disorders. It lowers our body's blood pressure, and releases waste and accumulated toxins in our body through sweat to improve our body's condition.

Interested in these foot baths and foot baths, various types of foot baths, foot baths, and half-baths were developed. These products can be divided into wet method and dry method according to the method of transmitting heat to the user's body or affected part.

In the wet method, there is a hot water method for treating the affected area by directly contacting the affected part with water heated by a heater and a steam method for heating steam generated by heating a bucket containing various medicines. There are two types of dry method: radiation method in which direct heat is radiated using far-infrared radiation and fumigation method for fumigation of various medicines.

In addition, the hot water method of the wet method is an indirect heating method in which the heating wire is indirectly heated by installing the hot wire at the bottom of the foot bath according to the method of making hot water, and the direct heating that directly heats by installing an electric heating tube, a heating plate or a heat engine in the foot bath. There is a way. In addition, a steam heating method for circulating the steam generated in the steam generator and supplying it to a heat exchanger installed in the foot bath to heat the water of the foot bath has also been developed. Another form of wet method is spraying. Spraying is to apply a constant pressure to the water heated to a constant temperature and then spray directly on the body of the bather to obtain the effect of half body bath and left bath.

 In the related art, a hot water method using hot water in which water contained in a footbath space is directly or indirectly heated is mainly used.

A water supply hose 342 is connected between the reservoir 314 and the steam generator 350, and a steam supply hose 334 is connected between the steam generator 350 and the foot bath 203.

The steam generator 350 has a heating cylinder 351 having a predetermined diameter, a heater 352 wound around the outer peripheral surface of the heating cylinder 351 to heat the heating cylinder 351, and the heating cylinder 351 Water injection port 353 installed at the lower end of the heating cylinder and injecting water into the lower end of the heating cylinder 351, and water vapor generated at the water surface of the heating cylinder 351 is installed at the upper end of the heating cylinder 351. The steam discharge port 354 for discharging to the outside, the temperature measuring unit 357 is installed in close contact with the outer peripheral surface of the heating cylinder 351 to measure the temperature of the heating cylinder 351, and measured by the temperature measuring instrument 357 It is configured to include a switch 358 to control the power supplied to the heater 352 according to the temperature. And it is configured to further include a power supply unit and control unit (A) not shown.

The heating cylinder 351 is an elongated cylinder made of a thin metal plate, both the upper end and the lower end are open, and the height has a length of about 2 to 10 times the diameter.

A heater 352 made of a wire or a plate-shaped hot wire is installed at the lower end of the outer circumferential surface of the heating cylinder 351. The heater 352 converts electrical energy into heat to heat the heating cylinder 351 to 100 ° C or more. The heater 352 is protected by being wrapped with insulation or insulation.

The temperature measuring device 357 is installed at the upper end of the outer circumferential surface of the heating cylinder 351. The temperature measuring device 357 is wound around the outer circumferential surface of the heating cylinder 351 and is attached to one surface of the heat conduction band 362 and the heat conduction band 362 for transferring the heat of the heating cylinder 351. And a temperature sensor 363 for generating an electrical signal corresponding to the temperature of 351.

For example, the temperature sensor 363 is made of a thermocouple (thermocouple) for joining two different metals together and measuring the temperature by the difference in electromotive force. That is, different voltages are output according to the temperature of the temperature sensor 363.

Therefore, the switch 358 interrupts the power supplied to the heater 352 according to the electric signal (voltage) output from the temperature measuring instrument 357. For example, when the heating cylinder 351 rises above the maximum set temperature, the power is cut off, and when it falls below the minimum set temperature, the power is re-applied.

In addition, an electrical signal (voltage) output from the temperature sensor 363 may be provided to the controller A to be described later, and used as a control signal for operating the pump 370 or controlling various valves 372.

On the other hand, the heating cylinder 351 according to the present invention by installing a steam discharge port 354 on the top to press the steam generated from the water surface of the heating cylinder 351 to a predetermined pressure to inject to the outside. That is, the steam discharge port 354 is characterized in that the steam discharge hole 364 having a diameter much smaller than the diameter of the heating cylinder 351 is provided.

As described above, the heating cylinder 351 according to the present invention has a longer length than the width, and is heated at the upper end thereof because a steam discharge hole 364 having a diameter much smaller than that of the heating cylinder 351 is provided. Steam generated from the water surface of the cylinder 351 is injected at a constant pressure.

The steam discharge port 354 is composed of an upper disk 365 for sealing the upper end of the heating cylinder 351, and an elastic fixing member 368 for fixing the upper disk 365 to the upper end of the heating cylinder 351. . At this time, the upper disc (365) is formed with a steam discharge hole (364) having a much smaller diameter than the diameter of the heating cylinder 351 and the steam discharged through the steam discharge hole (364) outside the steam supply hose ( A steam outlet 366 is installed to discharge to the 343.

The pump 370 can supply the desired amount of water when desired and can freely change the internal level of the heating cylinder 351.

 The pump 370 operates by an ON switch of a controller (not shown) to supply water, thereby raising the water level of the heating cylinder 351. On the other hand, when the water level of the heating cylinder 351 reaches a high level, the pump 370 is automatically turned off (OFF) by a water level meter (not shown). For this purpose, a level gauge (not shown) may be installed in the heating cylinder 351.

In addition, the pump 370 may be operated by the temperature meter 357 to measure the temperature of the heating cylinder 351. For example, when the water level of the heating cylinder 351 falls in the state in which the heater 352 operates, the temperature of the heating cylinder 351 increases. In addition, the temperature measuring device 357 installed in the heating cylinder 351 generates an electrical signal when the temperature rises above the set temperature to operate the pump 370 to supply water. And when water is supplied to the heating cylinder 351, the temperature of the heating cylinder 351 is dropped, the temperature measuring device 357 generates an electrical signal to stop the operation of the pump 370 to stop the pump 370.
