Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a steam generator for spraying onto the face, etc. in beauty and barbering.

(Prior Art) In recent years, vacuum suction and brushing have been performed in beauty treatments while applying water vapor to the face. Also, in barbering, steam is applied to the face in order to provide the necessary moisture and temperature for shaving.

The steam used for these has conventionally been obtained by heating water that has been placed in a container in advance with a heater and boiling it. Therefore, a preparation time of 30 minutes or more was required from the time the heating was started to the time it came to a boil.

(Purpose of the invention) In order to eliminate the drawbacks of the above-mentioned conventional examples, the present invention provides a steam generator that continuously supplies water in small amounts to a heated evaporation chamber and sequentially instantaneously evaporates it. It is something.

According to the present invention, it takes only 1 minute from the start of heating until the evaporation chamber reaches the temperature required for instant evaporation.
It only takes about 30 seconds and can significantly reduce preparation time.

Hereinafter, embodiments will be described in detail with reference to the drawings.

(Example) FIGS. 1 and 2 show an example of the present invention. First, in FIG. 1, reference numeral 1 denotes an evaporation structure made of a thermally conductive metal, and is equipped with an evaporation chamber inside, an inlet 2 for introducing water into the evaporation chamber, and an outlet 3 for discharging evaporated water vapor. There is. Further, a plurality of holes (three in this case) into which pipe heaters 4 are mounted are provided in the lower part. Reference numeral 5 denotes a thermistor for temperature control attached to the side surface of the evaporator structure 1.

Furthermore, in Fig. 2, 6 is a water tank, 7 is a solenoid valve, and 8 is a 0.6 mm tip at the tip to limit the amount of water.
A water supply port 9 having a hole of φ is a water guide thin tube extending from the water supply port 8 to the bottom surface 10a of the evaporation chamber 10 of the evaporation structure 1, and is a heat-resistant silicon tube with an inner diameter of 2 mmφ. The bottom surface 10a of the evaporation chamber 10 is inclined so that water supplied to one end thereof flows toward the other end. The evaporation structure 1 has an upper half having a water inlet 2 and a steam outlet 3, and a lower half to which a heater 4 is attached, which are separately manufactured, and the two are fixed together by press-fitting. The material used here is brass, with nickel plating applied.

Reference numeral 11 denotes a heat insulating outer cover surrounding the evaporation structure 1 and the heater 4, and is made of an epoxy resin plate and a cylinder. Note that other materials include asbestos, glass fiber, etc. 12 is the evaporation structure 1
This is an O-ring made of heat-resistant rubber for floating the body from the outer sheath 11. 13 is water supply port 8 and inlet port 2
A tube 14 connects the outlet 3 and a steam blowing nozzle (not shown).

In the above configuration, when generating water vapor, first connect the power supply to the heater 4, and it will take approximately 1 minute to generate water vapor.
The temperature of the evaporation structure 1 reaches 180° C. in 30 seconds, and a signal from the thermistor 5 detecting this temperature activates the solenoid valve 7, and water is supplied from the water supply port 8. In this case, since the hole in the water supply port 8 is as small as 0.6 mmφ, water is continuously supplied little by little and guided to the bottom surface 10a of the evaporation chamber 10 through the water guide tube 9. The water that has reached the bottom surface 10a flows downward because the bottom surface 10a is inclined, and during this time it is heated by the high-temperature evaporation structure 1 and evaporated, and the water vapor passes through the outlet 3 and is sent to a blow-off nozzle (not shown). It is ejected from. The distance the ejected water vapor can reach depends on the diameter of the nozzle, but in the case of this example, it reaches approximately 60 cm from the nozzle due to the steam pressure. Evaporation structure 1 is 180±20
Temperature controlled at °C.

Here, if there is no water guide tube 9, the water coming out from the water supply port 8 becomes water droplets and falls intermittently onto the bottom surface 10a of the evaporation chamber. Therefore, the water vapor ejected from the nozzle due to instantaneous evaporation each time becomes intermittent.
It is not desirable because it causes so-called breathing. In this embodiment, a water guide thin tube 9 is provided, and its tip is connected to the bottom surface 1.
Since it is in contact with 0a, the flow of the supplied water is continuous, and therefore the ejection of water vapor is also continuous. Note that the tip of the water guide tube 9 is not necessarily located at the bottom surface 1.
Even if it is not in contact with 0a, if it reaches close to it, the water that comes out will bridge between the tip of the capillary and the bottom due to its surface tension, forming a continuous flow of water.

The bottom surface 10a of the evaporation chamber 10 is sloped, and the bottom surface 1
The arrangement in which the water supplied to one end of Oa flows toward the other end is extremely effective in heating and evaporating the water. If the bottom is horizontal, water will accumulate at the point where it was supplied, significantly reducing the efficiency of evaporation. In the case of this embodiment, the bottom surface 10a is sloped, but the evaporation structure 1 itself may be installed with a slight slope.

The water vapor outlet 3 is disposed at either the left or right end of the central portion of the bottom surface 10a in the direction of inclination. When the outlet is arranged on the line along which the supplied water flows on the bottom surface 10a, giant particles of water vapor generated by boiling fly directly into the outlet and are ejected from the nozzle. According to the configuration of this embodiment, it is possible to always obtain water vapor of fine particles that meet the intended use.

In this embodiment, brass is used as the evaporator structure 1, and nickel plating is applied to it. This nickel plating is necessary at least for the evaporation chamber 10 and the outlet. If only brass is used, there is no problem with the evaporation function itself, but the steam obtained has an odor, which is undesirable for the purpose of use. When the material is stainless steel, it does not have an odor, but its thermal conductivity is poor, which causes temperature variations in various parts of the evaporation structure, reducing evaporation efficiency. At the same time, the steam pressure decreases, and the distance the steam is blown from the nozzle also becomes shorter.

(Effects of the invention) As explained above, according to the invention, since water is continuously supplied to the evaporation chamber in small amounts and the water is instantaneously evaporated one after another, the preparation time can be significantly shortened. can.

In addition, the water supply section is equipped with a water guide tube that extends from the water supply means to one end of the bottom of the evaporation chamber and has its tip touching or near the bottom, so that the water is continuously supplied. Therefore, the steam is continuously ejected. Furthermore, by sloping the bottom surface of the evaporation chamber, a flow of water is created, that is, water does not accumulate, so the efficiency of heating and evaporation is extremely high. Furthermore, since the steam outlet is placed at either the left or right end of the center of the water flow, the large particles of steam generated by boiling are not discharged, and the fine particles that meet the purpose of use are removed. Water vapor is always available.
