  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Further, the present invention is not limited by this embodiment.

(Embodiment 1)
FIG. 1 is a partial cross-sectional view of a steam iron according to the first embodiment of the present invention. In FIG. 1, an iron body 1 is covered with a base 3 heated by a heater 2 and a vaporization chamber lid 4 fixed to the upper surface side of the base 3, and is ejected from an ejection port 5 formed on the hanging surface side of the base 3. A vaporizing chamber 6 for generating steam and a base cover 7 provided above the base 3 are provided.

  Above the base cover 7 of the iron body 1, a tank 8 for storing water is detachably attached to the iron body 1. The tank 8 includes an operation unit 9 that can be moved up and down, and a pump device 10 that is operated by the operation of the operation unit 9 and supplies the water stored therein to the vaporizing chamber 6.

  The water supply pipe 11 is a pipe for supplying water stored in the tank 8 to the pump device 10, and is arranged close to the tank bottom member 14 inside the tank 8. The water supply pipe 11 is formed of a flexible thermoplastic resin such as a transparent or translucent silicon resin. The water supply pipe 11 is watertightly connected to the water inlet 10 a of the pump device 10 and the water supply packing 12.

  The discharge port 13 of the pump device 10 is also watertightly connected to the tank bottom member 14 by the same water supply packing 12 as described above, and is closed by a check valve 15.

  The lid 16 sandwiches the check valve 15 with the bottom of the discharge port 13 of the pump device 10 to form a water passage 17 below the tank 8, an inlet 19 of the water guide 18 that forms a water guide, rubber, etc. It has the opening part 21 watertightly connected by the connection packing 20 formed with the flexible material of this. The thermally responsive on-off valve device 22 controls the supply of water to the vaporizing chamber 6 based on the temperature of the base 3.

  With the configuration as described above, the discharge port 13 of the pump device 10 is communicated with the vaporizing chamber 6 through the water passage 17, and when the temperature of the base 3 is heated to a predetermined temperature, the operation unit 9 is operated. When operated, steam is ejected from the ejection port 5 of the base 3.

  Next, the operation and action of the steam iron configured as described above will be described.

When the vaporization chamber 6 is heated to the vaporization temperature of water, the thermally responsive member 23 senses the heat of the base 3 and reverses upward, pushes up the thermally responsive on-off valve device 22 and opens the water passage 17. In this state, when the operation unit 9 of the pump device 10 is moved up and down, the water sucked from the water supply pipe 11 is once sucked into the pump device 10 through the water supply packing 12, and the operation unit 9 is moved up and down again. The water in the pump device 10 pushes down the check valve 15 against the urging force of the check valve 15, and the water is pushed out from the discharge port 13 of the opened pump device 10 into the water passage 17. The water passes through the water conduit formed in the water conduit 18 and is supplied to the vaporizing chamber 6 to be vaporized, so that steam can be ejected.

  Here, since the water supply pipe 11 is formed of a flexible thermoplastic resin such as a transparent or translucent silicone resin, the water supply pipe 11 can be easily arranged in an arbitrary shape. The tank 8 can also be configured, and there is no need to worry about the external shape of the tank 8 or the internal components, and a steam iron with better design can be realized.

  In addition, since it is possible to prevent cracks due to bending of the water supply pipe 11, the steam iron provided with the tank 8 having a complicated shape can be maintained with a steam iron capable of maintaining a stable steam ejection ability over a long period of time. Can be realized.

  In addition, the water supply pipe 11 inside the tank 8 can be made inconspicuous from the outside, and foreign matter inside the water supply pipe 11 can be confirmed from the outside of the steam iron.

  Furthermore, since the water supply pipe 11, the discharge port 13, and the pump device 10 are watertightly connected by the water supply packing 12, the watertight connection configuration can be simplified, so that a stable steam ejection capability can be maintained over a long period of time. A possible and inexpensive steam iron can be realized.

As described above, the steam iron according to the present invention can be easily configured into a tank having a complicated shape, can make the water supply pipe inside the tank less noticeable from the outside, and can prevent contamination of foreign matter inside the water supply pipe. Since it can be confirmed from the outside of the iron and it is easy to find a defective portion, it is useful not only for a steam iron for wrinkling clothes and the like, but also for various steam-using devices.
