Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steam jet device which can be used as a steam massager for hair treatment or facial beauty by attaching a brush or a pine surger to the steam jet section.

Generally, this type of steam appliance is suitable for boiling steam that is humid and has a soft feel, so the structure is such that the main body has a built-in vaporizing chamber such as a steam generating can, and a cover can be attached and removed to cover the vaporizing chamber. It is a connected and separated type, and the volume of the vaporization chamber is set so that no more water can be added than the prescribed water injection amount, and there is no risk of hot water spewing out along with steam during use.

However, during use, the cover may be removed inadvertently, and the shock caused by the operation may cause hot water in the vaporizing chamber to spill out, posing a risk of burns.

The purpose of the present invention is to improve safety by integrating the conventional main body and cover into an integrated structure, and at the same time, to prevent more than a specified amount of water from entering the vaporization chamber in the integrated structure. It is something.

One embodiment will be described below with reference to the drawings. Reference numeral 1 denotes a bottomed cylindrical main body, which has a built-in vaporizing chamber 3 heated by a heater 2 below, and a vapor chamber above which communicates with the vaporizing chamber 3. 4 is formed.

Reference numeral 5 denotes a steam hole which opens at one end in the hollow part of the steam chamber 4 and opens toward the outside, and is used by attaching an attachment (not shown) such as a brush or a pine surge tool to a wall 6 formed in the vicinity of the steam hole. .

Reference numeral 7 denotes a tank formed above the vaporization chamber 4, and is provided with a removable lid 8, and the volume of the tank 7 is set to be less than the specified water injection amount for the vaporization chamber 3.

A communication port 9 is provided at the bottom of the tank 7, and one end thereof communicates with a passage 10 opening into the hollow portion of the steam chamber 4.

Reference numeral 11 denotes an electromagnetic drive source built into the main body 1, which is equipped with a solenoid 12 that can be freely extended and retracted.It is normally fitted shallowly, but when energized, it is pulled in deeply by the electromagnetic action of the coil.

This electromagnetic drive source 11 is connected to a circuit that is opened and closed by a thermostat 13 fixed to the vaporization chamber 3, and when the thermostat 13 is turned off, it is energized and turns on the solenoid 1.
It is configured to draw in 2.

Reference numeral 14 denotes an operating rod connected to the solenoid 12, which has an on-off valve 16 connected to it facing the communication port 9, and a spring 15.
It is always energized upward.

In the above configuration, the thermostat 13 is normally ON, the on-off valve 16 is closed, and the tank γ can be filled with water.

In this state, electricity is applied to the heaters 2 and 2, and when the vaporization chamber 3 reaches a predetermined temperature (approximately 110° C. to 120° C.), the thermostat 13 is set to 0FFL, the electromagnetic drive source 11 is driven, and the on-off valve 16 is opened.

As a result, water in the tank 7 flows through the passage 10 to the vaporization chamber 3.
The temperature of the vaporization chamber 3 decreases, the thermostat 13 is turned on, the power to the electromagnetic drive source 11 is cut off, and the on-off valve 16 is closed.

Then, the water in the vaporization chamber 3 is heated, vaporized, and ejected from the steam hole 5.

At this time, since the amount of water in the tank 7 sent into the vaporization chamber 3 is less than the specified amount of water in the vaporization chamber 3, hot water will not splash out from the steam hole 5 along with the steam.

After a while, when the water in the vaporization chamber 3 disappears, the temperature rise causes the thermostat 13 to go to 0FFL, and the electromagnetically driven valve 11 operates to open the on-off valve 16.

Therefore, if the water in the tank 7 is pumped into the vaporization chamber 3 and then filled again in the tank 7, it can be used automatically and continuously.

On the other hand, this steam jet device has a steam chamber 4 etc. formed in the main body 1 and does not use a conventional cover, so there is no chance of the user inadvertently removing the cover and covering himself with boiling water in the vaporization chamber 3. .

As described above, according to the present invention, it is possible to eliminate the burn accidents that occur when the main body and cover are separated, and
When the vaporization chamber is empty, a thermally responsive member is activated to inject only the specified amount of water, so it is possible not only to inadvertently inject more than the specified amount of water, but also to avoid overfilling the specified amount due to over-filling. Water injection can also be prevented, and safety is significantly improved, such as by reliably preventing hot water from spilling out due to excessive water injection.

In addition, in the present invention, since the electromagnetic drive source described above is controlled using a thermostat, there is no need for a special control member, and moreover, the movement of the thermostat is converted into electricity, and the electromagnetic drive source of the opening/closing valve is electrically controlled. Since the device is operated at the same time, there are no malfunctions like those caused by mechanical operation, and the device can be made compact and of high quality.
