Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a steam iron with a steam increasing device for general household use.

Conventional Structure and Problems There is known a steam iron equipped with a steam increasing device that can temporarily supply a large amount of water to a vaporization chamber in order to enhance the wrinkle-removal effect during ironing. This steam increasing device is generally operated by, for example, a manual pump device 1 as shown in FIG. In other words, by moving the button 2 up and down, the water in the tank 3 is transferred to the cylinder 4.
The structure is such that the gas is sucked up into the vaporizing chamber 5 and sent into the vaporizing chamber 5.

Such a manual pop device 1 is in addition to a conventional device for generating or stopping steam.

However, this manual pump device 1 can be operated at any time simply by moving the button 2 up and down. Therefore, when the vaporization chamber 3 is not heated or the temperature has not reached sufficient temperature to vaporize the water, water will leak out, causing stains on clothes and corroding the vaporization chamber. Due to the above inconvenience, the original effect of the steam increasing device was not fully demonstrated.

Purpose of the Invention The present invention provides a steam j
A steam iron with a %lft device is provided for 4M.

Structure of the Invention In order to achieve the above object, the present invention includes a base, a vaporization chamber provided on the base, a tank disposed above the base, and a pump device for supplying water in the tank to the vaporization chamber. By being equipped with a thermal response device that controls the supply of water to the vaporization chamber by this pump device, if the vaporization chamber is not heated to a temperature that can vaporize water, water will not flow out even if the pump device is operated. It was made so that it would not be supplied.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In the figure, 10 is a base in which a heater 11 is embedded;
A vaporization chamber 12 and a steam hole 13 are provided. 1
4 is a cover that covers the base 10 from above; 15 is a handle 16;
A tank 17 is located at the front of the tank and is detachably installed on the wall 14, and communicates with the vaporization chamber 12 through a cylindrical backing 18 through a drip nozzle installed at the bottom of the tuck 15 of the cigarette. Reference numeral 19 denotes a manual opening/closing device that opens and closes this dripping nozzle 17 to switch between steam and dry.
Operated by 0.

Reference numeral 21 denotes a pump device that is manually operated independently of the manual opening/closing device 19, and pumps water in the tank 15 into the vaporization chamber 1.
Supply to 2. 22 is a cylinder, and a piston 723 integrated with a button is slidably provided thereon. 24 is a water suction pipe that has a water suction hole 25 at the bottom of the tank 15 and communicates with the cylinder 22; 26 is a water suction pipe that communicates with the cylinder 22 through the water suction pipe 24;
The water supply pipe discharges the water sucked into the tank 15 to the vaporization chamber 12, and together with the water suction pipe 24, it constitutes a water supply channel 27 for supplying the water in the tank 15 to the vaporization chamber 12.

Reference numeral 28 denotes an on-off valve fitted to the lower end of the water suction pipe 24, which is slidably provided through the bottom of the tank 15, has two openings at the top, and is opened downward by a spring 30 at the lower end of the water suction pipe 24. The structure is such that the water absorption hole 25 is closed by being biased by the water absorption hole 25. Reference numeral 31 denotes a backing that projects the on-off valve 28 below the tank 15 and seals it watertight; one end of the backing is attached to the on-off valve 28, and the sealed state is maintained in response to the vertical movement of the on-off valve 28. . 32 is a thermally responsive member such as a bimetal provided on the base 10 side facing the opening/closing valve 28, which senses the heat of the base 10 and reverses itself so as to generate a vertical stroke. Reference numeral 33 indicates the vertical movement caused by the reversal operation of the thermally responsive member 32.
28, and is supported by a guide plate 34 on the base 1o side.

That is, the water suction pipe 24 of the pump device 21 is connected to the base 1.
It is controlled by a thermal response device 35 that operates by sensing the heat of the o.

In the above configuration, although the pump device 21 is configured to manually operate the piston 23 at any time to supply water in the tank 15 to the vaporization chamber 12, the vaporization chamber 12 reaches a temperature at which water can be vaporized. When not in use, the on-off valve 28 closes the water suction hole 26 of the water suction pipe 24, as shown in FIG.

Then, when the base 10 is heated by the heater 11 and the vaporization chamber 12 reaches a temperature at which water can be vaporized, the thermally responsive member 32 senses the heat and performs a reverse operation, as shown in FIG. The opening/closing valve 28 is pushed up through the opening/closing valve 28. Therefore, the opening 29 provided in this on-off valve 28 matches the water suction hole 25 to communicate the water suction pipe 24 and the tack 15, and the tank 1
The water in 5 becomes ready to be sent to the vaporization chamber 12, and the water is sent to the vaporization chamber 12 by the user's arbitrary operation, and the water is normally sent to the drip nozzle 17.
It is possible to increase the amount of steam added to the steam supplied from the pump or to eject steam by supplying water from the pump device 21 alone.

In this way, the pump device 21 can always supply water to the vaporization chamber 12 only when the temperature of the vaporization chamber 12 is sufficient to vaporize the water.

In the embodiment, the thermally responsive member 32 is made of bimetal, but is not limited to this, and may be any member that operates by sensing the heat of the base 10. Also,
Although the opening/closing valve 28 also opens and closes on the water suction pipe 24 side of the pump device 27, it may be opened and closed on the water supply pipe 26 side. The point is that when the temperature of the vaporization chamber 12 is not high enough to evaporate water, it is sufficient that the pump device 21 cannot supply water to the vaporization chamber 12 side.

Effects of the Invention As described above, the steam iron of the present invention completely solves various problems caused by user's carelessness or erroneous operation by controlling the supply of water to the vaporization chamber by the pump device using a thermal response device. At the same time, the increased amount of steam can fully demonstrate the original effect of improving the finish of clothes, and has the effect of increasing work efficiency.
