Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a steam iron in which a water inlet and a water tank are communicated through a water pipe.

[Technical background of the invention and its problems]

A steam iron has a water tank inside its main body, and the water in the water tank is dripped into the vaporization chamber of the base to generate steam, and this steam is sequentially jetted out from the bottom of the base. . A water inlet is provided on the front surface of the iron body, and this water inlet communicates with a water tank via a water pipe, and water is injected into the water tank from this water inlet as necessary. The connection between the water pipe and the water tank is the first
As shown in the figure, this is carried out using a connecting tube a made of an elastic material. That is, opening c of water tank b
The lower half of the connecting tube a hits the outer periphery of the connecting tube a, and in this state, the lower end of the water pipe d is inserted into the inner periphery of the upper half of the connecting tube a, and the connecting tube a hits the outer periphery of this lower end. There is.

However, with such a structure, the water pipe d and the connecting tube a contact each other over a large area, which adds a large resistance to the insertion of the water pipe d, making assembly troublesome, and also prevents foreign matter from forming on the outer periphery of the water pipe d. If it had adhered to it, it would get caught between the water pipe d and the connecting tube a, creating a gap between them, and there was a risk that the water in the water tank b would leak through the gap.

[Purpose of invention]

The present invention was developed with these points in mind, and its purpose is to make it possible to easily insert water pipes and achieve efficient assembly, and to prevent foreign matter from adhering to the outer periphery of water pipes. To provide a steam iron in which the outer periphery of a water pipe can always be tightly attached to a connecting cylinder by accurately removing such a problem.

[Summary of the idea]

In the present invention, the connecting cylinder is integrally formed of a cylinder part that fits into the opening of the water tank and a projecting part that projects inward from one end edge of the cylinder part, and the peripheral edge of the leading end of the projecting part is This is a sliding contact ring with a circular cross section, and the part extending from this ring to the cylindrical portion is a thin-walled part, and a water pipe is inserted inside the sliding contact ring, and this insertion causes the thin-walled part to elastically curve and deform. , a steam iron characterized by a sliding contact ring that is attached to a water pipe.

[Example of idea]

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 2 to 5. 1 in the figure is a base made of aluminum die-casting, and this base 1 has a heater 2.
is cast, and a vaporization chamber 3 is formed on the upper surface, and this vaporization chamber 3 connects to the conduction chamber 4 and the ejection hole 5.
It communicates with the lower surface side of the base 1 through it. The upper surface of the base 1 is covered with a metal cover 6, a heat shield plate 7 made of synthetic resin is provided on the upper surface of this cover 6, and a handle 8 made of synthetic resin is attached to the upper surface of this heat shield plate 7. There is. A flat water tank 9 is provided inside the handle 8, and this water tank 9 has an opening 10 formed on the upper surface of the front end, and a nozzle 12 connected to the lower surface of the front end through a nozzle packing 11. The nozzle 12 faces the vaporization chamber 3. Then, the water in the water tank 9 is dripped into the vaporization chamber 3 through the nozzle 12 by vertical operation of the opening/closing rod 13. This water is vaporized by the heat of the base 1 and becomes steam, and this steam flows from the conduction chamber 4 to the ejection hole 5. After that, the liquid is ejected sequentially to the lower surface of the base 1.

A water inlet body 14 made of synthetic resin is provided on the front end surface of the handle 8, and a water inlet 15 is provided in this water inlet body 14.
is formed. A water pipe 16 is provided inside the handle 8 and is integral with the handle 8. One end of the water pipe 16 fits into the water inlet 15 through a packing 17, and the other end is made of an elastic material such as rubber. The water inlet 15 is connected to the opening 10 of the water tank 9 through a connecting tube 18, so that the water inlet 15 communicates with the water tank 9 and water can be injected into the water tank 9 from the water inlet 15. It's summery.

As shown in FIGS. 3 and 4, the connecting tube 18 is integrally formed of a cylindrical portion 19 and a projecting portion 20 extending inward from the periphery of one end of the cylindrical portion 19 at a substantially right angle. There is. The peripheral edge of the distal end of the projecting portion 20 forms a sliding ring 21 having a circular cross section. Further, from this sliding contact ring 21 to the cylindrical portion 19
The portion extending over becomes a thin wall portion 22. Furthermore, a protrusion 23 is integrally formed on the inner circumference of the cylindrical portion 19 along the circumferential direction thereof. The cylindrical portion 19 is located on the outer periphery of the opening 10 of the water tank 9, and the projecting portion 20 is located on the outer periphery of the opening 10 of the water tank 9.
The water tank 9 and the water pipe 16 are thereby connected to each other. In addition,
24 is an opening/closing lid that opens and closes the water inlet 15, and 25 is a temperature regulator that controls energization of the heater 2 to adjust the temperature of the base 1.

Next, the procedure for assembling the water pipe 16 to the water tank 9 will be described. First, the cylindrical part 19 of the connecting cylinder 18 is press-fitted into the outer periphery of the opening 10 of the water tank 9. At this time, even if foreign matter adheres to the outer periphery of the opening 10, it will be scraped off by the protrusion 23, so that the foreign matter will not be caught inside the cylindrical part 19, and the protrusion 23 will be removed from the opening. 10
Since the cylindrical portion 19 is strongly pressed against the outer peripheral surface of the opening 10, the cylindrical portion 19 is tightly fitted into the opening 10, and water leakage between the two is reliably prevented. After the connecting tube 18 is attached to the opening 10 of the water tank 9 in this manner, the water pipe 16 is inserted inside the sliding ring 21. At this time, as shown in FIG. 5a, the thin wall portion 22 is elastically deformed and the sliding ring 21 is displaced in the insertion direction of the water pipe 16, and the sliding ring 21 is aligned with the water pipe 16. Since there is only contact, the water pipe can be inserted smoothly. Now, as shown in FIG.
2, the thin part 2
2 has a large area and comes into close contact with the outer circumferential surface of the water pipe 16, making it difficult to insert the water pipe 16. However, in this embodiment, since the sliding ring 21 having a circular cross section is present at the periphery of the thin walled portion 22, the thin walled portion 22 does not come into close contact with each other, and therefore the water pipe 16 can be inserted smoothly. can be done. Furthermore, even if foreign matter adheres to the outer circumferential surface of the water pipe 16 during this insertion, it will be scraped off by the sliding ring 21 and will not be caught between them. Since the area is in contact with the circumferential surface of the water pipe 16, the contact pressure is large and the two are tightly fitted, thereby reliably preventing water from leaking between the two.

In the above embodiment, the water pipe and the water inlet are separate bodies, but they may be integrated, or the water pipe may be configured separately from the handle.

[Effects of the invention] As explained above, according to the invention, it is possible to smoothly insert the water pipe into the connecting tube, achieve efficient assembly, and prevent foreign matter from adhering to the outer periphery of the water pipe. Even if it is, it can be accurately removed and the connecting tube can be tightly attached to the outer periphery of the water pipe at all times, so that water leakage in the water tank can be reliably prevented.
