Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 is a perspective view showing the overall appearance of the portable steam generator 100 according to the present invention, Figure 2 is a plan view showing the internal configuration of the case of the steam generator 100 removed.

1 and 2, the portable steam generator 100 includes a case 10, a steam generator 20 installed inside the case, and a power supply unit 30 for supplying power to the steam generator. And a controller 40 electrically connected to the steam generator and the power supply to control the power supplied to the steam generator.

In addition, one side is connected to the steam generating unit through the conduit (C1) and the other side is connected to the external water supply source (S) through the other conduit (C2) and also electrically connected to the control unit, the steam generating unit, It further comprises a water supply means 50 for supplying water for the steam generation intermittently as needed. The water supply means 50 is preferably a small motor pump, but may be used as long as it is a means for supplying water using power even if the motor pump is not.

As shown in the figure, while the water supply means 50 continuously or intermittently supplies water to the steam generator 20 through an external water supply source, the steam generator receives power from the power supply unit 30 to generate steam. The water introduced into the inside is heated to generate steam and then supplied to the outside through the steam supply means 21. At this time, the water supply means to adjust the amount of water supplied to the steam generating unit in accordance with the water level inside the steam generating unit, this is made by the controller.

3 is a cross-sectional view of the steam generator 20 cut along the line A-A 'of FIG.

As shown in FIG. 3, a steam supply means 21 for supplying steam to the outside is installed at an outer upper portion of the steam generator, and a heating means 22 for heating water accommodated inside the steam generator 20. And first and second temperature measurement and on / off control installed on the inner upper portion of the steam generator to measure the temperature inside the steam generator to control on / off the entire portable steam generator 100 according to the temperature. Apparatuses 23 and 23 'and water level measuring means 24 are installed on the inner upper part of the steam generator and measure the water level inside the steam generator.

The heating means 22 is an electric heater device using an electrical resistance.

The first and second temperature measurement and the on / off control device (23, 23 ') continuously measures the temperature inside the steam generating unit 20, if the temperature inside the steam generating unit 20 rises above a prescribed value steam In the present invention, the first and second temperature measurement and on / off control devices 23 and 23 'are constituted by cutting off the power supply to the generator. The first and second temperature measurement and on / off control devices 23, 23 'are connected in series, so that when one fails to function due to a failure, the other functions.

The water level measuring means 24 is composed of an electric resistance type, and uses an electric resistance value that depends on the surface area of the water level measuring means in contact with water.

4 schematically shows a circuit configuration according to the present invention.

One wire L1 in the power supply unit 30, for example, an input line for convenience, is connected to the heating means 22 of the steam generator 20, and the output line L2 from the heating means is the steam generator 20. Is connected to the first temperature measurement and on / off control device 23, i.e., bimetal, and the output line L3 from the first temperature measurement and on / off control device 23 is connected to the second temperature measurement and on / off control device 23. Connected to an off control device 23 ', an output line L4 from the second temperature measurement and on / off control device 23' is connected to a control unit 40, and an output from the control unit 40. The line L5 is configured with a power supply circuit to be connected to the power supply unit 30.

Then, the water supply means 50 and the water level measuring means 24 is connected to the control unit 40. The water supply means 50 and the water level measuring means 24 are not for supplying power such as the power supply unit, but for the operation of the water supply unit and the water level measuring unit, unlike the power supply unit. The power is quite low.

Referring to the operation of the portable steam generating device 100 according to the present invention configured as described above are as follows. First, when power is supplied through the power supply unit while water is supplied into the steam generator 20, since the first and second temperature measuring and on / off control devices 23 are in the on state, the steam generator Power is supplied to the heating means 22 to generate steam by heating the water inside the steam generator while the heating means generates heat. The generated steam releases steam to the outside through the steam supply means 21.

As such, when the steam generator 20 continuously generates steam, and the water level inside the steam generator is lower than the prescribed value, the controller 40 detects this through the water level measuring means 24 and supplies water. The means 50 is operated to supply water to the steam generator 20, and when the water level inside the steam generator rises above a prescribed value, the operation of the water supply means 50 is stopped. Therefore, the water level inside the steam generator 20 is always within a certain range.

On the other hand, when the temperature inside the steam generator rises above the prescribed value by the heating means 22 inside the steam generator 20, for example, when the temperature rises above 120 ° C., the first and second temperature measurements and on / off control are performed. Either of the devices 23, 23 ′ will be off. Bimetals that are connected to each other are separated from each other and are electrically opened. Accordingly, the power supplied from the power supply to the heating means of the steam generator is cut off. Then, when the temperature inside the steam generator falls below the prescribed value, for example, when the temperature falls below 120 ° C, the first or second temperature measuring and on / off control device 23 or 23 ', i.e., bimetal is turned on. In this state, electric power is supplied from the power supply unit to the heating means so that the heating means heats the water inside the steam generator to generate steam. The reason for using two temperature measurement and on / off control device in the present invention is that even if a fault occurs in any one of the devices, the other one can function so that the overheating of the steam generator is reliably shut off. To do so.

As described above, the portable steam generator of the present invention can be used regardless of the place, unlike the portable steam generator of the prior art, and since the two temperature measuring and on / off control devices use bimetal, Even if the portable steam generator was overheated because the control unit 40 of the portable steam generator failed, the water supply means or the heating means could not be controlled. The power can be easily cut off to prevent accidents due to overheating.

On the other hand, in the steam generator of the prior art, since the heating means is used in direct contact with water, the so-called wet heater is used, so that if the heating means continues to operate when the water is not supplied sufficiently to the steam generating unit, the heating means is operated. Often the case was broken by its own heat.

In order to solve this problem, in the present invention, as shown in FIG. 5, a heater 22 ′ 2 is installed inside the heater cover 22 ′ 1 having excellent thermal conductivity. That is, a heater is installed inside the heater cover so as not to contact the heater cover. The heater may be installed inside the heater cover by forming a first screw thread at one end of the heater cover, and forming a second screw thread corresponding to the first screw thread at one end of the heater, and screwing the threads to the inside of the heater cover. The heater is installed in the

As the heating means is configured as described above, in the state where there is no water in the steam generating portion, the temperature sensing and on / off control device composed of bimetal do not operate, and thus the heating means is continuously supplied to the heater 22'2. Even if heat is generated, the heater is not damaged by the heat of the heater itself. In addition, when the heater reaches its endurance life and does not want a function as a heating element, only the heater needs to be replaced.

In the present invention, since a high temperature heat, such as 120 ° C heat is generated from the steam generator, the parts near the steam generator, in particular the conduit made of plastic material may be damaged by heat, so that the predetermined heat insulating material of the conduits (D) enclosed the conduit to prevent the conduit from being damaged by the heat of the steam generator.
