BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a partially cutaway face treatment device. The facial device 1 includes a steam pot 2 containing purified water as a steam source, a heater 3 for heating the purified water in the steam pot 2, and a splash prevention device 4 provided on the upper portion of the steam pot 2. An arm 5 whose one end is connected to the splash prevention device 4
And a nozzle 6 connected to the other end of the arm 5 for ejecting ionized steam, and a controller 7 for controlling the heater 3 and the like.

FIG. 2 (a) is a side sectional view of the molten-metal flying prevention device 4, and FIG. 2 (b) is a sectional view taken along line XX of FIG. 2 (a). As shown in FIG. 2A, the hot water splash prevention device 4 has a buffer chamber 8 for convection of steam generated in the steam pot 2. The lower surface 9 of the buffer chamber 8 has an introduction pipe 10 for introducing steam and a condensate passage 11 for returning water droplets condensed on the inner wall of the buffer chamber 4 to the steam kettle 2.
have. Further, an opening 13 for communicating with the arm 5 is formed on the front surface 12 of the buffer chamber 4. As is clear from FIGS. 1 and 2A, the cross-sectional area of the buffer chamber 8 is sufficiently larger than the cross-sectional areas of the introduction pipe 10 and the arm.

Further, in FIG. 2A, a high-pressure discharge electrode 14 for ionizing steam is provided near the position where the opening 13 is formed in the buffer chamber 8, and the introduction pipe 10 is provided with A hot water jet detection unit 15 is provided for detecting the hot water jet in the steam. As shown in FIG. 1, the high-voltage discharge electrode 14 and the splashed water detection means 15
Is connected to the control device 7, and the control device 7 receives the signal from the hot water jet detection means 15 and also heats the heater 3.
It also has a function of controlling the high-voltage discharge electrode 14.

As shown in FIG. 2A, the upper surface 16 of the buffer chamber 8 is inclined so that it rises from the rear surface 17 toward the front surface 11. In addition, the lower surface 9 of the buffer chamber 8
The condensate passage 11 can be roughly divided into a front portion 9a provided with an opening 11a and a rear portion 9b on the introduction pipe 10 side. The rear part 9b is the front part 9a.
2 has a ridge 18 which is ridged with respect to the front surface 12, and the shape of the ridge 18 is such that the front surface 12 side is lower than the rear surface 17 side, and as shown in FIG. In addition, it has an inclination so that the left and right sides are lower than the center. Further, the opening 10a of the introduction tube 10 is provided at a position protruding from the raised portion 18 by a predetermined distance.

The high-voltage discharge electrodes 14, 14 are composed of two rod electrodes projecting from the side surfaces 19, 19 of the buffer chamber 8 so as to face each other. High-voltage discharge electrode 1
4, 14 are arranged in the vicinity of the center of the buffer chamber 8 so as to be spaced apart from each other by applying a high voltage between the high-voltage discharge electrodes 14, 14 to discharge the two high-voltage discharge electrodes 14. The steam passing through can be ionized.

On the other hand, as shown in FIG. 3, the molten metal jet detection means 15 provided in the introduction pipe 10 has rod electrodes 20, 20 inserted so as to face each other in the introduction pipe 10, and rod electrodes 20 ,.
It comprises holding members 21 and 22 for fixing 20. Since no high voltage is applied between the rod electrodes 20, 20, they are normally in an insulating state. However, if a predetermined amount or more of molten metal is mixed in the steam passing through the introduction pipe 10, the rod-shaped electrodes 20, 20 are electrically connected via the molten metal.

Next, an explanation will be given of the operation of the hot water splash prevention device 4 and the operation of the facial treatment device 1 using the hot water splash prevention device 4. First, the heater 3 heats the purified water in the steam kettle 2 to generate steam. The generated steam is introduced into the buffer chamber 8 through the introduction pipe 10 of the splash prevention device 4. The introduced steam convects in the buffer chamber 8 by changing the flow direction due to the gradient of the upper surface 16 of the buffer chamber 8.

The steam introduced into the buffer chamber 8 is
Convection in the buffer chamber 8 and high pressure discharge electrode 14,
After being ionized by the discharge of 14, the buffer chamber 8 is supplied to the arm 5 through the opening 13 of the front surface 12 thereof.
It is ejected toward the human body or the like from the nozzle 6 provided at the tip of the.

Here, steam may condense into water droplets during convection in the buffer chamber 8, and these water droplets collect on the front portion 9a of the lower surface 9 and pass through the condensate passage 11. Returned to the steam kettle 2. For example, the water droplets that have condensed on the rear surface 17 of the buffer chamber 9 are
After flowing to the side and the front of the buffer chamber 8, the lower surface 9
Is returned to the steam kettle 2 via the condensate passage 11 from the front part 9a. Similarly, even when minute steam is mixed in the steam, it is condensed while the steam is convection in the buffer chamber 8 and is returned to the steam pot 2 via the condensate passage 11.

On the other hand, when the amount of splashes mixed in the steam becomes large or increases, the rod electrodes 20, 20 of the splashes detecting means 15 provided in the introduction pipe 10 become conductive via the splashes. . The control device 7 which has detected the conduction of the hot water splash detecting means 15 determines that the hot water splash has occurred in the steam pot 2, stops the heater 3, and issues a warning to an operation panel (not shown).

When the amount of splattering increases or increases, the splattering detecting means 15 prevents the generation of splattering, and when the amount of splattering is small or small, the buffer chamber 8 causes the splattering arm 5 to move. Since it is prevented from being introduced into the body, hot water does not mix into the ionized steam ejected from the nozzle 6 to the human body.

Further, as shown in FIG. 2 (b), the condensate channel 1
Since the opening 11a of No. 1 is at the lowest position on the lower surface 9 of the buffer chamber 8 and the opening 10a of the introducing pipe 10 is located at a position higher than the lower surface 9, it is possible to prevent condensed water droplets from flowing back to the introducing pipe 10. it can. Therefore, it is possible to prevent the hot water jet detection means 15 from becoming conductive due to the condensed water droplets.

The present invention is not limited to the embodiment and can be widely applied and used. For example, the opening 10 a of the introduction pipe 10 may be formed on the rear surface 17 of the buffer chamber 8.
You may arrange toward. Since more steam can be convected in the buffer chamber 8, it becomes easier for dew condensation on the minute hot water spray. In addition, the hot water splash prevention device 4
Instead of being used for the application device 1, it can also be used for a humidifier. It is possible to prevent hot water from entering the steam ejected from the humidifier.

[0019]

EFFECTS OF THE INVENTION Since the present invention provides a hot water splash prevention device having a buffer chamber, steam can be once convected in the buffer chamber, and even if a small amount of hot water is mixed in the steam chamber, Condensation can be formed on the inner wall.
Therefore, it is possible to prevent minute hot water from entering the steam. Further, since the hot water spray prevention device having the buffer chamber is used in the facial device for spraying the ionized steam to the human body, the hot water spray does not mix into the ionized steam.
