Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to a steam generator for heating a face with steam when washing the face. However, the present invention does not specify the use of the steam generator, and can be used, for example, for sucking steam into the throat in the case of a cold or the like.

[0002]

2. Description of the Related Art When washing a face, it is better to open pores widely. The pores are opened by heating. Facial care devices for spraying and heating heated mist on the face have been developed (see JP-B-53-35073 and JP-B-53-431).
No. 07 publication). These facial beauty devices spray water in a mist state and heat it, or heat water to generate steam. Opening the pores of the face using these facial treatment devices, and then washing the face in an ideal state can be achieved.

[0003] A steam generator used for face washing can be conveniently used by being integrated with the face washing apparatus. The inventor has developed an apparatus shown in FIG. 1 incorporating a steam generator. In this apparatus, a steam cover 2 is detachably attached to a water cup 1, a heating case 4 is provided on the steam cover 2, and the heater 3 is built in the heating case 4. This face washing device is used as follows. A predetermined amount of water is put into the water cup 1. The steam cover 2 is attached to the water cup 1, and the water in the water cup 1 flows into the small heating case 4 from the inflow port 4A. The heater 3 of the heating case 4 is energized. The heater 3 heats the water in the heating case 4 and causes the water to boil to generate steam. The steam generated in the heating case 4 flows out of the steam outlet 4B into the water cup 1, and the inside of the water cup 1 is filled with the steam. In this state, when the face is put on the steam hole 2A of the steam cover 2, the face is heated by the steam. After heating the face with steam for a certain time, the power supply to the heater 3 is stopped. Remove the steam cover 2 from the water cup 1. At this time, the warm water remaining in the heating case 4 flows out into the water cup 1. The blower 5 is operated to pressurize the compressed air to the bubble generating member 6. The air ejected from the bubble generating member 6 generates countless bubbles in the water in the water cup 1. When the face is put on the water in the water cup 1 in this state, the face is washed with bubbles. After washing the face, the water in the water cup 1 is discarded. The face-washing device of the present invention used in the above state has a feature that it can be conveniently used because the water in the water cup 1 is used for both steam generation water and face-washing water.

[0004]

However, the apparatus shown in FIG. 1 has a disadvantage that it is difficult to quantify the amount of steam generated. This is because a large amount of water stored in the water cup is heated to produce steam, so that even if steam is generated for an extremely long time, the amount of water does not decrease so much. Whether the steam generator heats the face before washing the face or sucks it into the throat, it is desirable to quantify the amount of steam generated. In the apparatus of FIG. 1, in order to quantify the amount of generated steam, it is necessary to measure the use time by using a clock or the like, and there is a disadvantage that it is troublesome.

Further, the apparatus shown in FIG. 1 has a disadvantage that scale is deposited on a heater portion as the apparatus is used. The scale cannot be easily removed because the scale is formed by depositing metals such as calcium and magnesium contained in water and adheres very hardly. When the scale adheres, not only does the thermal efficiency decrease, but also there is a disadvantage that it becomes dirty and cannot be used neatly. In order to eliminate the scale, it is necessary to remove the scale components dissolved in the water put in the water cup.However, since the water cup is filled with a large amount of water, It is not economical to process large amounts of water. In particular, the water in the water cup is heated only for a small portion to form steam, and the remaining water is used for face washing and discarded every time. For this reason, it is extremely uneconomical to treat a large amount of water to remove scale components.

Further, the apparatus shown in FIG. 1 can be conveniently used for heating the face with steam, but cannot always be conveniently used for, for example, sucking steam into the throat.
This is because a large amount of water not used as steam is used in a water cup.

The present inventor has sought to eliminate this drawback.
The steam generator shown in FIG. 2 was developed. In the apparatus shown in this figure, an appropriate amount of water to be used as steam is put into a water cassette 8, and this water is caused to flow into a steam generator 9 to generate steam. As described above, the apparatus for replenishing water with the small water cassette 8 fills the water cassette 8 with the filter material 14 for removing scale components, or, between the water cassette and the steam generator (not shown). To remove scale components. Filter media processes water to be steam,
It has a long life and can be used at low cost.

However, the steam generator of this structure has a drawback that heated water droplets are easily ejected from the nozzle 23 together with the steam. This is because the heated water droplets may be mixed with the steam heated by the heater 11 and boiled. If heated water droplets are sprayed with steam, the face and throat may be burned.

The present invention has been developed with the aim of further solving this drawback. An important object of the present invention is to prevent a heated water droplet from being ejected together with steam.
An object of the present invention is to provide a steam generator that can be used safely.

[0010]

A steam generator according to the present invention is an improved steam generator which generates steam by heating water with a heater 11 and discharges the steam from a nozzle 23.
It has the following unique configuration. The apparatus of the present invention includes a heater 1
Between the nozzle 1 and the nozzle 23, a buffer chamber 34 for reducing the flow rate of steam is provided. Further, a baffle plate 35 is disposed between the inlet and the outlet of the buffer chamber 34 to prevent the steam flowing from the inlet from flowing directly to the outlet. The flow velocity of the steam flowing into the buffer chamber 34 from the inlet is slowed down in the buffer chamber 34, and the flowing steam collides with the baffle plate 35, the steam flow path 36 is bent by the baffle plate 35 and flows out to the outlet. It is configured as follows.

Further, in the steam generator according to a second aspect of the present invention, an inlet is provided at the bottom of the buffer chamber 34, and an outlet is provided at a position different from the inlet in a horizontal position at an upper portion. Is provided with a baffle plate 35. This buffer room 3
4 is a flow path 36 for the steam flowing from the inlet,
It is configured to bend at 5 and to pass between the baffle plate 35 and the inner surface of the buffer chamber 34 and flow out of the outlet.

The steam generator includes a water cassette 8 detachably mounted on the main body, a steam generating section 9 for heating water discharged from the water cassette 8 to form steam, and a detachable water cassette 8. An upper opening tank case 10 is provided to be freely mounted.

The tank case 10 has a cylindrical shape with an open top, and has a bottom connected to the steam generator 9.
Is supplied to the steam generator 9. The tank case 10 is supplied with a fixed amount of water from the water cassette 8,
It is always kept at a certain level of water surface. Tank case 10
And the water surface level of the steam generator 9 is kept substantially the same.
If a large amount of water is supplied to the steam generating section 9 at a time, the heater 11 cannot convert the water into steam in a short time. The tank case 10 adjusts the amount of water supplied to the steam generator 9 so that the steam generator 9 heats water to steam almost instantaneously. In order for the tank case 10 to adjust the amount of water supplied to the steam generator 9, the tank case 10 is always maintained at a constant water level. To realize this, the water cassette 8
Supplies water when the water level of the tank case 10 is lower than the set value, and does not supply water when the water level is higher than the set value. The tank case 10 and the steam generator 9 are connected by an inverted U-shaped siphon tube 12.

The water cassette 8 has a water chamber 13 in an upper part when mounted on the tank case 10, and the water in the water chamber 13 is passed below the water chamber 13 so as to pass through the water case 13.
And a filter medium 14 to be supplied to the apparatus. Water cassette 8
As shown in FIG. 7, the upper case comprises a cylindrical casing 8A which is open at the top and bottom, and a cap 8B which can be attached to and detached from the cylindrical casing 8A in a watertight manner. In the water cassette 8, water is poured into a cap 8B removed from the cylindrical casing 8A, inserted into the cylindrical casing 8A, and then mounted upside down on the tank case 10.

The cap 8B is formed in a cylindrical shape having one end closed with plastic. The cap 8B is designed to have an internal volume capable of supplying about 100 cc of water, for example. As shown in the sectional view of FIG. 8, the outer diameter of the cap 8B is substantially equal to the inner diameter of the cylindrical casing 8A so that the cap 8B can be inserted in a watertight manner inside the cylindrical casing 8A. The O-ring 15 is inserted, and the O-ring 15 is attached to the cylindrical casing 8A in a watertight manner.

The cylindrical casing 8A includes a tank case 10
, The lower portion is filled with a filter medium 14.
The filtering material 14 removes scale components contained in water passing therethrough, and for example, an ion exchange resin, activated carbon, or the like can be used. As the filtering material 14, a granular material and a material formed into a predetermined shape are used. Granular filter media 1
4 is filled with a mesh material 24 at the lower end and the middle so that the filter material 14 does not leak.

The cylindrical casing 8A has an on-off valve 16 at its center.
Is provided. The air pipe 17 extends from the lower end of the cylindrical casing 8A to the upper part of the cap 8B, penetrating through the filter medium 14. The air pipe 17 supplies air to the water chamber 13 formed inside the cap 8B. When air is supplied to the water chamber 13, the water stored therein passes through the filter medium 14 and is discharged from the lower end of the cylindrical casing 8A. If air is not supplied to the water chamber 13, the water chamber 13 is airtightly sealed, so that water does not pass through the filter medium 14 and is discharged from the cylindrical casing 8A. The air pipe 17 has a tapered lower end to increase the opening area. This is because if the opening area of the lower end is small, the lower end of the air pipe 17 is closed by water, so that air cannot be supplied from the air pipe 17 to the water chamber 13.

The lower end of the air pipe 17 is
Determine a water level of zero. When the water surface of the tank case 10 becomes lower than the lower end of the air pipe 17, the air pipe 17 supplies air to the water chamber 13 and the water surface becomes
When the height of the air pipe 17 is higher than the lower end of the air pipe 7, the lower end of the air pipe 17 is closed by water, and air is not supplied to the water chamber 13. The lower end of the air pipe 17 is set several mm higher than the lower end surface of the cylindrical casing 8A. This is for storing water at a depth of several mm at the bottom of the tank case 10.

In order to supply air to the lower end of the air pipe 17, a gap through which air can pass is provided between the water cassette 8 and the tank case 10. Further, as shown in FIGS. 6 and 7, the lower end of the cylindrical casing 8A projects a plurality of legs 8a so that air flows into the inside of the cylindrical casing 8A.

The air pipe 17 constitutes an on-off valve 16 that opens when the water cassette 8 is mounted on the tank case 10 and closes when the water cassette 8 is removed from the tank case 10. The on-off valve 16 includes a valve element 18 that closes the upper end of the air pipe 17, and is connected to the valve element 18 to form an air pipe 17.
And a spring 20 that elastically presses the rod 19 downward to bring the valve element 18 into close contact with the upper end of the air pipe 17. This on-off valve 1
The valve 6 is closed by the spring 20 pressing the valve body 18 against the air pipe 17 via the rod 19. As shown in FIG. 8, when the water cassette 8 is mounted on the tank case 10,
The pressing portion 21 fixed to the tank case 10 is
To open the valve body 18 away from the air pipe 17.

The valve element 18 is formed into a conical shape with natural or synthetic rubber so that the upper end of the cylindrical air pipe 17 can be closed airtightly without any gap. The rod 19 is designed to be long enough to close the upper end of the air pipe 17 with the lower end spring 20 pulling the valve body 18.
The pressing portion 21 of the tank case 10 is provided at the lower end of the rod 19.
The column-shaped rubber flange 22 is fixed so as to be pressed.

When the valve element 18 is separated from the upper end of the air pipe 17 and the on-off valve 16 is opened, water is supplied from the water cassette 8 to the tank case 10, and the tank case 10 has a constant water level. Water is stored in the level.

The water in the tank case 10 is
At 2, it flows into the steam generator 9. The steam generator 9 is shown in FIG.
As shown in FIG. 10 to FIG. 10, a heating chamber 28 for temporarily storing and heating supplied water and a heater 11 for heating water to be steam are provided. The heating chamber 28 includes the siphon tube 12
The boiler unit is disposed above the discharge unit for evaporating water. As shown in FIG. 10, the heating chamber 28 is provided inside the boiler main body 29, and both sides are sealed by the heater 11. The boiler body 29 and the heater 11 are connected via a clamping screw 30. The boiler body 29 and the heater 11 are watertightly connected with a packing 31 sandwiched between contact surfaces. The heating chamber 28 having this structure has a feature that water can be efficiently heated because water directly contacts the heater 11 on the side surface. However, the heating chamber can be formed by forming a tank with a closed boiler main body and bringing the outer periphery of the tank into contact with a heater to heat the tank.

As shown in FIG. 10, the heating chamber 28 is connected to the siphon tube 12 via an inflow passage 32. The water supplied from the siphon tube 12 is:
The gas flows into the heating chamber 28 through an inflow passage 32 branched right and left. The water stored in the heating chamber 28 is heated by the heater 11 and is discharged as steam. Heating room 2
The water in 8 is held on the same water surface as the water surface of the tank case 10. Therefore, when the heater 11 turns the water into steam and the amount of water decreases and the water level in the heating chamber 28 decreases, water is supplied from the tank case 10.

The steam generator 9 is connected to the nozzle 23 via a buffer chamber 34, as shown in FIG. Buffer room 3
Numeral 4 is connected between the heating chamber 28 and the nozzle 23 to prevent the heated water droplets generated in the steam generator 9 from being ejected from the nozzle 23 together with the steam. Buffer room 34
Has a large internal volume to slow down the steam flow. Further, as shown in the perspective view of FIG. 11 and the horizontal sectional view of FIG. 12, the buffer chamber 34 is provided with a baffle plate 35 to prevent steam from being directly injected. The baffle plate 35 is disposed between the inlet and the outlet of the steam, and is disposed at a position where the steam flowing from the inlet is prevented from flowing directly from the outlet.

The buffer chamber 34 in these figures has a cylindrical shape as a whole, and has an inlet at the bottom and an outlet at the top. The entrance and the exit are located at different horizontal positions, that is, in FIG. 11, the entrance is arranged at the left end and the exit is arranged at the right end. The baffle plate 35 is located between the entrance and the exit, and is disposed so as to surround the entrance. Further, the baffle 35
The upper end is connected to the ceiling of the buffer room 34, and the lower end is connected to the buffer room 34.
Slightly off the bottom of the In the buffer chamber 34 having this structure, the steam flowing upward from the inlet vigorously collides with the space surrounded by the baffle plate 35 and the ceiling of the buffer chamber 34 to lose kinetic energy and leak from both sides of the baffle plate 35. To the outlet. For this reason, there is a feature that the heated water droplet can be extremely effectively prevented from being injected together with the steam.

The steam from which water droplets have been removed in the buffer chamber 34 is injected from the nozzle 23. As shown in FIG. 4, the steam generator has a nozzle 23 provided on the upper part of the main body. The nozzle 23 has a structure that can be freely opened and closed as indicated by an arrow in FIG. As shown in FIG. 14, the nozzle 23 having this structure jets steam in an open state. Nozzle 2
The steam released from 3 heats the face and the like.

Further, as shown in FIG. 6, the steam generator turns on the heater 11 in accordance with the opening and closing of the nozzle 23.
A limit switch 33 for turning off the switch is provided.
The limit switch 33 is turned on when the nozzle 23 is open, and energizes the heater 11. When the nozzle 23 is closed, the limit switch 33 is turned off, the power is not supplied to the heater 11, and steam is not injected from the nozzle 23. As described above, the steam generator including the limit switch 33 has the feature that the heater 11 is turned off while the nozzle 23 is closed, so that the steam generator can be used safely without filling the inside with steam.

The steam generator having the above structure is used as follows. (1) Take out the water cassette 8 from the tank case 10. (2) Remove the cap 8B of the water cassette 8 and supply water thereto. (3) Insert the cap 8B into the cylindrical casing 8A,
Water is supplied to the water chamber 13 of the water cassette 8. (4) Attach the water cassette 8 to the tank case 10. (5) The water cassette 8 attached to the tank case 10
The valve element 18 is pushed up, and the on-off valve 16 is opened. (6) When the on-off valve 16 is opened, air is supplied to the water chamber 13 through the air pipe 17, and the water in the water chamber 13 flows down to the tank case 10 through the filter medium 14. (7) When the water surface of the tank case 10 rises and reaches the lower end of the air pipe 17, the air pipe 17 is blocked by the water surface, and the air pipe 17 stops supplying air to the water chamber 13. For this reason, the water chamber 13 is airtightly closed, and water does not flow down the filter medium 14. Therefore, water is stored at a constant water level at the bottom of the tank case 10. (8) The water in the tank case 10 flows into the steam generator 9 through the siphon pipe 12. (9) The water that has flowed into the heating chamber 28 of the steam generator 9 is heated by the heater 11 to become steam, and passes through the buffer chamber 34 and is discharged from the nozzle 23. As the steam passes through the buffer chamber 34, the heated water droplets mixed with the steam are removed,
Only steam is injected from the nozzle 23. (10) When the water level in the heating chamber 28 decreases and the water level decreases, the water level in the tank case 10 also decreases. This is because they are connected by the siphon tube 12. (11) When the water level of the tank case 10 decreases, the lower end of the air pipe 17 separates from the water level, passes through the air pipe 17, and is supplied with air to the water chamber 13. (12) The air supplied to the water chamber 13 is
After passing through the filter material 14, it flows down to the tank case 10.
Therefore, the water level of the tank case 10 rises. (13) When the water level of the tank case 10 rises, the lower end of the air pipe 17 is closed, so that water is not replenished from the water chamber 13 and water is replenished to the heating chamber 28 through the siphon tube 12. . This state is repeated, and the tank case 10 and the heating chamber 28 are kept at the same water level, and the heater 11 discharges water from the nozzle 23 as steam. (14) When the water in the water chamber 13 runs out, the nozzle 23 stops emitting steam. The heater 11 is, for example, approximately 100 c
c) is released as steam for about 10 minutes.

The steam generator is used for heating the face as described above. The apparatus shown in FIGS. 4 and 5 has a face-washing device as an integral structure. This device heats the face with steam to open the pores of the skin, and then operates the blower 5 of the face-washing device to pressurize air to the bubble generating member 6 and eject air from the bubble generating member 6. Then, countless bubbles are generated in the water in the water cup 1 and put a face on the water in the water cup 1,
The face can be washed with air bubbles.
