Description

  The present invention relates to a steam supply device used in the hairdressing and beauty industry for steaming the head hair and specific skin to promote the reaction of the drug, moisturizing, keeping warm, etc., particularly for the steam jetting part for jetting steam. Concerning structure.

  A steam supply device in the field of beauty and beauty has a structure in which water vapor generated by heating water is stored in a high-pressure state and ejected from a steam ejection portion via a conduit. In the structure, an electric heater that heats the steam as disclosed in, for example, Patent Document 1 is provided in the vicinity of the steam jetting part for the purpose of cooling and agglomerating the wet steam into dry steam. A steam with dryness is ejected by providing a space with a high heating temperature of the electric heater.

  In the structure of the conventional steam ejection part (for example, Patent Document 1), as shown in FIG. 2, three electric heaters 21 are bonded to the outer wall surface of the heat pipe 22 made of a metal material such as aluminum and provided with an internal space. It is. The nozzle 23, which is a portion for ejecting steam into the atmosphere, has a substantially spherical shape, and is provided with a plurality of steam ejection holes 26.

  Steam generated by heating water and stored in a high pressure state passes through the steam release valve section 2 and the steam conduit 3 shown in FIG. Since the total cross-sectional area of the plurality of steam outlet holes 26 applied to the nozzle 23 is much smaller than the cross-sectional area of the space in the heat pipe 22, the steam that has reached the heat pipe 22 is temporarily retained. Then, the steam is heated by the electrically controlled electric heater 21 and ejected from the plurality of steam ejection holes 26 provided to the nozzle 23 to the atmosphere.

  Here, in the structure of the conventional steam ejection part, the distance between the inner wall surface 23A of the nozzle 23 and the atmospheric wall surface 23B, that is, the thickness of the nozzle is about 1.0 mm to 2.0 mm. Moreover, the average thickness of the wall surface of the heat pipe 22 is 2.0 mm, and the inner diameter of the space is 18 mm in diameter. The space temperature in the heat pipe 22 by the electrically controlled electric heater 21 is around 200 ° C., and the temperature is controlled at a high temperature so that steam with dryness can be ejected.

JP 2010-29503 A (page 8, FIGS. 7 and 8)

  By the way, in the conventional steam ejection part structure, when steam with dryness is ejected, it is necessary to keep the space temperature in the heat pipe 22 at a high temperature (for example, 200 ° C.). The steam ejection part is located outside the steam supply apparatus main body, and is a part that is touched by the operator's hand. Means for insulating the steam ejection part block maintained at a high temperature is not easy. In addition, maintaining the space temperature in the heat pipe 22 at a high temperature results in the need to supply high electric power to the electric heater 21.

  The present invention has been made in view of the above-mentioned reasons, and the object of the present invention is to provide a steam heating section with good steam heating efficiency that can spray steam with high dryness without holding the inside of the heat pipe 22 at a high temperature. To provide a structure.

  In order to achieve the above object, the steam jet structure of the steam supply device for hairdressing and beauty according to claim 1 is characterized in that the steam generated by storing water in a sealed tank is generated and stored in a steam release valve and a conduit. Is supplied to the steam ejection part, and the steam is ejected into the atmosphere from the steam ejection part. The steam ejection part is formed of a material having good thermal conductivity such as aluminum, copper or an alloy thereof, and has a space for retaining steam and an electric heater for heating the steam in the space. The nozzle, which is the part that is ejected into the atmosphere, has a structure with a steam outlet hole that ejects one or more steams to the atmosphere, and has a steam outlet hole that ejects steam into the atmosphere. The thickness of a certain surface, that is, the thickness of the nozzle is made larger than the thickness of the wall surface constituting the space in which the steam is retained.

According to a second aspect of the invention, in the invention described in claim 1 relates to the structure of the steam jetting portion, the thickness of the wall members constituting the space for retention of steam jetted steam to the atmosphere The thickness of the end face provided with the steam outlet hole is 1.5 to 3 times.

In carrying out the present invention , the nozzle is detachable by providing a female screw part on the inner wall surface of the vapor jet part constituting the space in which the steam is retained, and providing the male screw part screwed into the female screw in the nozzle . Is preferred.

According to the cosmetic and cosmetic steam supply device of the first aspect of the present invention, steam with high dryness can be ejected even if the temperature of the space in which the steam is retained and heated is controlled and maintained at a low temperature (for example, 120 ° C.). In addition, it is possible to save the heat insulation cost of the steam ejection part and the electric power to the electric heater. Moreover, according to invention of Claim 2, vapor | steam with still higher dryness can be ejected.
Internal long term use of the steam jet unit, components such as commonly referred calcium carbonate and limescale contained in the tap water is deposited, it becomes a cause of heating efficiency degradation or off-flavor to the steam nozzle If the part is made detachable, the inner surface of the nozzle and the inner surface of the steam ejection part can be cleaned.

It is a schematic block diagram of the steam supply apparatus for hairdressing and beauty using the vapor | steam ejection part structure which concerns on embodiment of this invention. It is the conventional steam heating block diagram of a steam ejection part same as the above. It is a steam heating block diagram which concerns on this invention of a steam ejection part same as the above. It is a general view of the cross section of the steam heating block, heat insulating material, and exterior case of the same steam ejection part.

Hereinafter, preferred embodiments for carrying out the present invention will be described. As shown in FIG. 1, a hairdressing / cosmetic steam supply device using a steam jetting structure according to an embodiment of the present invention houses a tank 11 that stores water vapor generated by heating water in a high-pressure state. The apparatus main body 1, a water tap 14 for supplying water to the tank 11, a steam release valve section 2 for releasing the high-pressure steam in the tank 11, a steam conduit 3, steam as a path for jetting the high-pressure steam in the tank 11 to the atmosphere The ejection part main body 4 is a main member.
The tank 11 includes a tank heater 12 for heating water, a liquid level sensor 13 for detecting the amount of water, and a pressure sensor 7 for detecting the pressure in the tank 11 and an electric circuit board 6 are provided in the apparatus main body 1. . An operation panel substrate 5 for an operator to operate the apparatus is disposed on the upper outer surface of the apparatus main body 1.

  The water faucet 14 is sealed with a sealing shaft body 17 having a valve (for example, an O-ring) that seals the vapor pressure that can be inserted and removed by screwing and a knob 16 of the sealing shaft body 17. Has been. The knob 16 is turned, the sealing shaft body 17 is removed, and water is supplied from the water tap 14. The amount of water supply is displayed on the operation panel board 5 via the electrically connected liquid level sensor 13 and the electric circuit board 6. The knob 16 is turned to insert the sealing shaft body 17 into the water tap 14 to seal the tank 11. When the heater switch on the operation panel board 5 is pressed, the tank heater 12 is energized through the electric circuit board 6 and the water in the tank 11 is heated. The heated water generates water vapor and accumulates in the upper layer of the tank 11 with pressure. When the upper limit set value pressure (for example, 4 atm) of the measurement value of the pressure sensor 7 is reached, the energization to the tank heater 12 is stopped via the electric circuit board 6 and the heating of the water in the tank 11 is stopped. When the steam is ejected, the pressure decreases with time, and when the pressure sensor 7 decreases to a lower limit set value pressure (for example, 3.5 atm) of the measured value of the pressure sensor 7, the tank heater 12 is again connected via the electric circuit board 6. Is energized to heat water and generate steam. The inside of the tank 11 is repeated to maintain the vapor pressure at a specified pressure.

  The steam release valve portion 2 for releasing steam is a member having a valve function capable of sealing and releasing steam (for example, a needle valve), and the high pressure steam in the tank 11 is transferred to the steam release valve portion 2. The knob 2T provided in the above is rotated to open and stop the steam ejection. The steam conduit 3 is connected to the steam ejection part main body 4 with a soft material having heat resistance (for example, a fluorine tube).

  Here, the structure of the vapor | steam ejection part main body 4 of the vapor | steam supply apparatus for hairdressing according to this invention is demonstrated in detail. As shown in FIG. 4, the steam heating block 44 shown in FIG. 3, which will be described later, is covered with a glass wool heat insulating material 43 and is housed in a heat-resistant resin-molded cylinder 42 (for example, PBT). A resin-molded cylinder 42 is housed in a steam ejection handle 41, which is a heat-resistant resin-molded product molded into a shape with good handling properties in order to inject steam onto head hair and skin.

The steam heating block 44 as shown in FIG. 3 has a steam pipe 3 and a heat pipe 22 on the left side of the heat pipe 22 having a space in which the exterior is a hexahedron and the inside has a cylindrical (for example, inner diameter Φ18 mm) steam. The joint 25 for connecting the two is fixed.
On the other hand, on the inner side of the right side opening of the heat pipe 22, a female screw portion 22N that is screwed into the male screw portion 23N of the nozzle 23 is provided. The heat pipe 22 is made of a material having good thermal conductivity (for example, aluminum), and has an average wall thickness of 2 mm and a length of 26 mm. Three electric heaters 21 are attached to a trihedral body that is equally divided among the external hexahedrons of the heat pipe 22. The electric heater 21 is wired to the electric circuit board 6 and the temperature of the space in the heat pipe 22 is controlled to a set temperature (for example, 200 ° C.).

The nozzle 23 is provided with a male screw 23N that is screwed into the female screw 22N of the heat pipe 22. The jet end face from which the steam is jetted into the atmosphere has a spherical shape, and the thickness of the jet end face, that is, between 23A and 23B, is 6 mm, which is three times the average thickness of the wall surface of the heat pipe 22.
On the 6 mm-thick injection end face, six steam jet holes (for example, Φ1.5 mm) are arranged uniformly in a circle, and one more steam jet hole is arranged in the center of the circle. Such a nozzle 23 is screwed into the female thread portion 22N of the heat pipe 22, and a steam heating block 44 is formed.

  Water 2000 ml was supplied into the tank 11, the steam pressure set value in the tank 11 was changed from 4 atm to 3.5 atm with the pressure sensor 7, and the heating switch on the operation panel substrate 5 was pressed to start heating the water. . On the other hand, the steam heating block 44 is provided with a temperature adjustment volume on the electric circuit board 6 so that the space temperature in the heat pipe 22 can be set at both 200 ° C. and 120 ° C. Three types of nozzles 23 of 1.5 mm, 3 mm, and 6 mm are prepared between the thicknesses 23A and 23B of the jet end face from which the steam is jetted to the atmosphere, and each is screwed into the female threaded portion 22N of the heat pipe 22 and attached. , So that it can be removed. In addition, all the steam outlet holes of the nozzle 23 were set to Φ1.5 mm.

  In a room with a temperature and humidity of 25 ° C. and 60% RH, steam is jetted in a combination of a space temperature of 200 ° C. and 120 ° C. in the heat pipe 22 and a jet end face thickness of 1.5 mm, 3 mm, and 6 mm in the nozzle 23. Measure the temperature of the erupting steam 30cm from the end face of the glass with a mercury thermometer, apply the steam to the palm, set the highest level of dryness of the steam to 1, and in order 2, 3, 4 in order, the most dry feeling Table 1 shows the results of grade evaluation with a low level of 5.

The steam heating block 44 equipped with a 6 mm nozzle 23 in which the thickness between the nozzle injection end faces 23A and 23B is three times the average thickness of the wall surface of the heat pipe 22 is the highest in the dryness of the jet steam. High dryness was maintained even when the space temperature was reduced to 120 ° C. Further, the temperature of the ejected steam was the same at a space temperature of 200 ° C. and 120 ° C. in the heat pipe 22.
When the thickness between the nozzle injection end faces 23A and 23B is 1.5 mm, the drying level is 3 when the drying level is 200 ° C., and 5 when the drying level is 120 ° C. The value was 3 at 120 ° C., which was more effective than that at 1.5 mm. It is understood that the nozzle injection end face is more effective when the thickness is 6 mm.

  When the vapor pressure in the tank 11 is set to 4 atm, the boiling point is 143 ° C. in the saturated vapor pressure characteristic of water, and 143 ° C. vapor is stored in the tank 11. When the steam is sent into the heat pipe 22 through the open valve portion 2 and the steam conduit 3, since the steam has pressure, the spray end surface of the nozzle 23 is directly irradiated. It is presumed that the heating efficiency is improved because the jet end face portion of the nozzle 23 has a large thickness and the heat capacity is large, so that the steam latent heat possessed by the steam is not lost. The ejected steam with improved heating efficiency has a dry feeling, and it is considered that the temperature of the experienced steam is low due to the latent heat of steam.

As described above, the steam ejection part structure of the hairdressing and beauty steam supply apparatus according to the present invention has been described. However, the nozzle 23 and the heat pipe 22 can be attached and detached by screwing the male screw 23N and the female screw 22N, respectively. As a matter of course, the inside of the heating space of the heat pipe 22 could be observed and cleaned. In the steam supply apparatus for hairdressing and beauty, a means for cleaning and removing scale components such as calcium carbonate accumulated in the tank 11 that generates steam is actually performed. It is an integrated structure, and it is difficult to easily wash and maintain scale components such as accumulated calcium carbonate. In this case, if the nozzle 23 and the heat pipe 22 are screwed together so that the nozzle 23 can be easily removed, scale components such as calcium carbonate accumulated in the heat pipe 22 and the inner surface of the nozzle 23 can be removed. Easy to remove.
Moreover, although the thickness of the end face of heat pipe 22 itself was increased and the heating improvement of the steam was sought, the cross-sectional area of heat pipe 22 itself increased and the capability of the heater 21 needs to be improved. It has been found that the thickness of the nozzle injection end face of the nozzle 23 is the most effective for improving steam heating.
Further, although the nozzle 23 has the spherical surface, the same result was obtained even when it was a flat surface.
