Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steam iron for flattening clothes such as wrinkles.

[0002]

2. Description of the Related Art Conventionally, this type of steam iron has a structure as shown in, for example, Japanese Patent Laid-Open No. 60-3543, and specifically, it is as shown in FIG.

That is, reference numeral 1 is a base which forms a vaporization chamber 3 covered with a vaporization chamber lid 2, and a water conduit mounting plate 4 is attached to the upper surface of the base 1 with screws 5. Reference numeral 6 denotes a tank installed above the base 1. The tank 6 and the vaporization chamber 3 are connected by a water conduit 7. The water in the tank 6 is supplied to the vaporization chamber 3 through the water conduit 7. It is like this.

The water conduit 7 is formed by superimposing a water conduit main body 8 and a heat resistant water conduit packing 9, and is fixed to the water conduit mounting plate 4 to cover the upper surface side of the base 1. Had been placed.

[0005]

However, in such a structure, since the water conduit 7 is heated by the heat from the base 1, the water in the water conduit 7 is heated and boils during use. Bubbles are generated in the water conduit 7, and the bubbles disrupt the flow of water in the water conduit 7. As a result, there is a problem in that the water in the tank 6 cannot be smoothly supplied to the vaporization chamber 3 and the steam cannot be jetted stably.

[0006] Therefore, an object of the present invention is to obtain a steam iron which can prevent the generation of bubbles in the water conduit and can jet a stable steam.

[0007]

In order to achieve the above object, the steam iron of the present invention has a tank arranged above a cover covering the upper surface side of a base, and
A water conduit for supplying the water in the tank to the vaporization chamber is formed in the tank.

[0008]

With the above construction, the steam iron of the present invention can dispose the cover between the water conduit and the base, and can shield the water conduit from the heat of the base. Therefore, overheating of the water conduit can be prevented and the water can be maintained at a low temperature.

Further, since the tank is filled with water during use, the water serves to cool the water conduit,
Since the temperature of the headrace can be further lowered,
Water in the headrace can be prevented from boiling. As a result, bubbles are not generated in the water conduit, and stable steam can be jetted without interrupting the flow of water.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 10 is a base in which a heater 11 is embedded, and a vaporization chamber 12 is integrally formed. Thirteen
Is a vaporization chamber lid that covers the vaporization chamber 12. Reference numeral 14 denotes a heat-resistant resin cover disposed above the base 10 to form a space between the cover 10 and the base 10 to cover the upper surface side thereof.

Reference numeral 15 denotes a tank which is detachably arranged above the cover 14 and which is connected to the vaporizing chamber 12 through a nozzle 16 attached to the base 10 side so that water in the tank 15 is restricted. Is being supplied by
A connection packing 17 is provided between the base 10 and the nozzle 16.
Is provided.

Next, the tank 15 will be described in detail. The tank 15 is made of thermoplastic synthetic resin and is composed of a plurality of members 15a, 15b, 15c. 15a
The cylinder body 16 is integrally formed with the tank body. A tank bottom plate 15b is welded to the lower portion of the tank body 15a to form a water conduit 17 in the tank 15.

Reference numeral 18 denotes an opening / closing device which connects and disconnects the tank 15 and the water conduit 17, and has a ball valve 19 loosely fitted in the cylinder portion 16 and a spring 20 opposed to the lower end of the ball valve 19. Further, an opening / closing rod 21 arranged vertically movable in the cylinder portion 16, a spring 22 for urging the opening / closing rod 21 upward, a piston 23 positioned in the cylinder portion 16 and interlocked with the operation of the opening / closing rod 21, and It is composed of an operation button 24.

By operating the operation button 24 to move the opening / closing rod 21 up and down together with the spring 20, the flow of water from the small hole 25 provided in the lower portion of the cylinder 16 to the water conduit 17 can be arbitrarily controlled. By repeatedly performing the vertical movement operation of the operation button 24 by the piston 23, a large amount of water can be temporarily sent from the water conduit outlet 26 to the vaporization chamber 12 via the water conduit 17.

Next, the operation of the structure of this embodiment will be described. First, when the operation button 24 of the opening / closing device 18 is moved upward to raise the opening / closing rod 21 and the spring 20 to release the pressing of the ball valve 19, the water in the tank 15 causes the ball valve 19 to move in the cylinder 16 by buoyancy. To surface
It is possible to enter the water conduit 17 from the small hole 25 and be supplied to the vaporization chamber 12 from the water conduit outlet 26 to be vaporized and to eject steam.

At this time, since the water conduit 17 is thermally shielded from the base 10 by the cover 14, it can be maintained at a low temperature without being overheated, so that the water in the water conduit 17 boils. It is possible to smoothly flow into the vaporization chamber 12 without generating bubbles.

Further, since the water conduit 17 itself is formed in the tank 15, it is surrounded by the water stored in the tank 15, so that the water conduit 17 is constantly cooled by the water and the water inside the water conduit 17 is kept. The temperature of water can be kept even lower.

When the operation button 24 is held down, the spring 20 presses the ball valve 19 to close the small hole 25, and the water supply to the vaporization chamber 12 can be stopped.

FIG. 2 shows another embodiment of the present invention, in which the tank main body 15a and the tank bottom plate 15c are sealed with a backing 27 to form a water conduit 17. In addition to this, the water conduit may be configured independently.
The point is that the water conduit should be formed in the tank.

In the above-mentioned embodiment, the removable tank is explained, but if a cover is used instead of the tank bottom plate and a handle is used instead of the tank body, a steam is formed by the handle and the cover. It can also be used for ironing.

Further, in the embodiment, the opening and closing device has a structure in which a pump device is added, but it is sufficient if the communication between the tank and the water conduit can be opened and closed. Furthermore, in the embodiment, the amount of water supplied to the vaporization chamber by the nozzle is changed. Although limited, it goes without saying that you may go at the exit of the headrace.

[0022]

As described above, in the steam iron of the present invention, the tank is arranged above the cover covering the upper surface side of the base, and the water conduit for supplying the water in the tank to the vaporization chamber is formed in the tank. As a result, the cover can be arranged between the water conduit and the base, and the heat of the base can be cut off to prevent overheating of the water conduit.
The headrace can be cooled by the water filled in the tank.

Therefore, it is possible to prevent the water in the water conduit from boiling and to prevent the generation of bubbles in the water conduit by keeping the water conduit at a low temperature. Therefore, the flow of water from the tank to the vaporization chamber can be prevented. Stable steam can be spouted without breaking.
