As another method, a thermoelectric module exposed to the working space or a separate heating means may be used so that the airflow inside the working space becomes a hot atmosphere. The thermoelectric module may include a thermoelectric module and a calf thermoelectric module.

Hereinafter, an embodiment of a high-temperature atomization device that provides a high-temperature mist is presented. Since the related system of the leg management apparatus including the reservoir 10 is the same as the room temperature atomization apparatus of FIGS. 9 to 11, the same description applies, and the description thereof will be omitted. Unlike the room temperature atomization device, the atomization device of the following embodiment provides a high-temperature mist, and thus may be referred to as a high-temperature atomization device.

12 is a cross-sectional view showing an example of an atomizing device. Referring to FIG. 12, the atomization device 130 will be described in detail as follows.

Referring to FIG. 12, the atomization device 130 includes a tank 610 in which water is accommodated, a heater 640 mounted inside the tank 610, and a water level measuring the water level of the atomization device 130. It may include a sensor 660 and a temperature sensor 670 that measures the temperature of the atomizer 130.

The water level sensor 660 may generally include a common electrode 662, a low level electrode 664 and a high level electrode 666. The high and low water levels can be detected by whether the common electrode 662 and the high water level electrode 664 are energized or the common electrode 662 and the low level electrode 666 are energized.

A water supply hose 620 for supplying water may be connected to one side of the atomizer 130, and a steam supply line 642 for discharging steam in a form of mist may be connected to the other side. A nozzle 650 having a predetermined shape may be provided at the front end of the steam supply line 642.

One end of the water supply hose 620 is connected to a water supply unit that supplies water to the atomization device, and the nozzle 650 at the front end of the steam supply line 642, that is, the steam discharge port is located at a predetermined position on the inner surface of the working space 500 It is connected, it is possible to spray high-temperature mist into the interior of the working space (500).

Here, the water supply unit may be connected to the water storage tank 10. A valve may be provided at the connection part with the storage tank.

That is, in this embodiment, any device capable of generating high-temperature mist can be used as an atomizing device. For example, a heater may be installed directly around or inside a predetermined case through which water passes. Accordingly, it is also possible to use it in a method of heating water without being accommodated in a predetermined space (hereinafter, referred to as "tube heating method" for convenience). In the tube heating type atomizer, water flowing into the atomizer is heated and converted into a high-temperature mist.

13 is a diagram schematically showing a system associated with the atomization device. Is also.

Referring to FIG. 13, in this embodiment, as a water supply unit that supplies water to the atomization device 130, the reservoir 10 may store a predetermined amount of water therein, and the rear of the atomization device 130 Can be provided in

It is preferable that a pump 683 is provided between the water storage tank 10 and the atomization device 130. The pump 683 is capable of forward and reverse rotation, so that water may be supplied to the atomizer 130, or the residual water of the atomizer 130 may be recovered if necessary. Recovering the residual water in this way is to prevent or minimize the accumulation of inorganic matter inside the atomizer as scale. If the amount of minerals contained in the water is small or negligible, a pump capable of only forward rotation may be used.

The residual water recovered into the storage tank 10 may be disposed of by emptying the storage tank 10. At this time, the concentration of inorganic matter may be high in the residual water.

A failure of the atomization device 130 may be prevented by applying the pump 683 capable of forward and reverse rotation. Specifically, in the high-temperature atomization apparatus of the barrel heating method of providing mist by boiling water, inorganic matter remains in the tank 610 after the water boils. Failure of the atomization device may occur due to the remaining inorganic matter. In order to eliminate this problem, when the atomization apparatus operates for a certain period of time and residual water remains below a certain level, the scale can be reduced by removing the residual water inside the tank 610.

The pump could also be replaced with an on/off valve. This is possible by using the water head difference between the water storage tank 10 and the atomization device 130. That is, it will be possible to supply water from the reservoir 10 to the atomizer 130 using gravity. In this case, water can be automatically supplied from the water supply unit to the steam generator by turning on the on/off valve.

It is preferable that water is supplied to the lower portion of the atomizer 130 and the steam is discharged from the upper portion of the atomizer 130. This configuration is advantageous in recovering the residual water of the atomization device 130. Of course, as shown in FIG. 12, water may be supplied to the top of the atomization device 130. In this case, a separate drainage structure may be installed to recover residual water.

It is preferable that a safety valve 681 is provided in the steam flow path, that is, the steam supply line 642 for discharging steam from the atomization device 130. This is to prevent safety accidents in advance by preventing the steam pressure from increasing when the steam flow path, in particular, the nozzle 650 is blocked.

The foot bath function according to the high temperature atomization device will be described in more detail.

The high-temperature mist supplied by the atomization device 130 may be directly attached to the user's leg, or the high-temperature mist may be condensed in the leg to perform a foot bath function. .

In order to allow the high-temperature mist to reach the entire region of the user's leg, the blowing device 101 may be additionally operated.

When the blower 101 provides a hot airflow, the airflow inside the working space can continuously heat the mist attached to the leg. In this case, even if the high-temperature mist cools, the foot bath can be continued.

The hot airflow of the blowing device can be achieved by the blowing device having a separate heating means. As another method, a thermoelectric module exposed to the working space or a separate heating means may be used so that the airflow inside the working space becomes a hot atmosphere. The thermoelectric module may include a thermoelectric module and a calf thermoelectric module.

To this end, a mist supply slit 1303 having a slit structure that is elongated in the left and right sides of the main vertical extension part 111 may be provided.

Since the mist supply slit 1303 is elongated left and right, steam can be supplied to both left and right legs of the user. Since the mist supply slit 1303 is elongated, it is possible to prevent the mist from being concentrated and supplied to any part of the leg. A diffuser may be provided between the nozzles 37 and 650 and the mist supply slit 1303.

Since the discharge port of the mist supply slit 1303 is provided wide, it is possible to prevent the mist from being concentrated on any part of the leg, thereby preventing burns due to high-temperature mist. To this end, a diffuser and a baffle may be provided between the nozzle 650 and the mist supply slit 1303.

In order to smoothly supply the mist to the working space 500, the blower 101 may be operated together when the mist is supplied.
