Description

[Detailed Description of the Invention] The present invention relates to an improvement in an iron in which a water storage tank is provided with a spray mechanism.

In general, ironing imparts plastic deformation to fibers through the action of heat, moisture, and pressure. In other words, the arrangement of fiber molecules is changed using the water vapor energy generated by vaporizing water with heat and the pressure generated by the weight of the iron and the force of the operator, and the wrinkles in the fibers are smoothed out and pleats are added. It is something to do. Therefore, heat, moisture, and pressure are all essential for achieving a good iron finish.

In conventional ironing, a so-called steam iron equipped with a steam generation mechanism is known as an iron that supplies moisture to fibers. Some steam irons have been developed that allow the amount of steam generated to be increased or decreased, but since steam is generated using the heat of heating the iron,
The amount of steam generated cannot be increased too much, and there is a limit to the supply of moisture.

Therefore, recently, we installed a water tank in the iron,
It has been proposed to provide a spray mechanism in this water storage tank and use this spray mechanism to supply moisture to the fibers during ironing. According to such a device, the amount of water supplied is certainly not limited as is the case with the above-mentioned steam mechanism.

However, in order to provide a spray mechanism in a water storage tank, many parts such as cylinders and pistons that make up this spray mechanism are required, which increases the cost.Moreover, many parts must be watertightly bonded to the water storage tank. As a result, the assembly work is time-consuming and leads to problems such as a decrease in productivity.

This idea was made based on the above circumstances,
The purpose is to provide an iron that reduces the number of parts and simplifies assembly work by integrally molding a cylinder constituting a spray mechanism with a water storage tank.

An embodiment of the present invention will be described below with reference to the drawings. 1 in the figure is the iron body. This iron body 1 includes a base 2 formed by aluminum die-casting in which a heater (not shown) is embedded, a cover 3 that is placed on the top surface of this base 2, a heat shield plate 4 that is laminated on the top surface of this cover 3, and a heat shield plate 4 that is laminated on the top surface of this cover 3. hot plate 4
It consists of a handle body 5 provided on the rear end side of the upper surface.
This handle body 5 has a cavity 6 in its central part,
This cavity 6 forms a handle 7 at the top. The handle 7 has a hollow shape, and an engaging portion 8 consisting of a stepped portion is formed at the open end. Further, the handle body 5 is provided with a temperature regulator 9 in its center portion for adjusting the temperature at which the base 2 is heated by the heater. In the iron main body 1 thus constructed, a water storage tank 10 is detachably provided on the front end side of the upper surface of the heat shield plate 4. The water storage tank 10 is made of transparent synthetic resin, for example, so that the side surface is L-shaped, and a water inlet body 11 made of opaque synthetic resin is provided on the front surface, and a water inlet body 11 made of opaque synthetic resin is provided on the bottom surface. A switching valve 12 is provided for causing water in the water storage tank 10 to drop into an evaporation chamber (not shown) formed in the base 2. A recess 13 is formed in the upper surface of the water storage tank 10, and this recess 13 is closed with a cover plate 14. This cover plate 14 has the switching valve 12
A first operating button 15 for switching the spray mechanism 16 provided in the recess 13 and a second operating button 17 for operating the spray mechanism 16 provided in the recess 13 are provided.
The spray mechanism 16 is constructed as follows. That is, a cylinder 19 forming a cylinder chamber and a water suction pipe 20 whose lower end faces the inner bottom of the water storage tank 10 and whose upper end is connected to the cylinder 19 are integrally formed on the top plate 18 forming the recess 13 of the water storage tank 10. has been done. Also, cylinder 1
A valve body 21 is housed in the interior of the valve body 9 so as to close the upper end opening of the water suction pipe 20, and a piston 22 is housed inside the valve body 9.
is movable. This piston 22
A shaft 23 extends from the shaft 23, and the second
An operation button 17 is integrally provided, and this second operation button 17 is biased in the upward direction by a spring 17a. Further, a connecting pipe 24 is integrally provided on the peripheral wall of the cylinder 19, and this connecting pipe 24
A water conduit 25 is connected at one end to the . A spray nozzle 27 is provided at the other end of the water pipe 25 so as to face the through hole 26 formed in the water inlet body 11 . Therefore, by repeating the pressing operation of the second operation button 17, the water in the water storage tank 10 is sucked into the cylinder 19 from the water suction pipe 20, and then from the spray nozzle 27 via the water conduit pipe 25. It is now being sprayed.

Further, the first operating button 15 is similarly urged in the upward direction by a spring 28, and an operating rod 29 is coupled at its upper end so that it moves in conjunction with the vertical movement of the first operating button 15. There is. The lower end of the operating rod 29 is led to the switching valve 12. When the first operating button 15 is pressed to lower the operating rod 29, the switching valve 12 is closed and water in the water storage tank 10 stops dripping into the evaporation chamber.

Further, the above-mentioned cover plate 14 is provided on the back side of the water storage tank 10.
An L-shaped tongue piece 30 is extended from the tongue piece 30.
When the water storage tank 10 is attached to the iron body 1, the handle 7 is elastically engaged with the engaging portion 8 of the handle 7.

According to the above configuration, the spray mechanism 1
The cylinder 19 of No. 6 was integrally molded on the top plate 18 forming the water storage tank 10. Therefore, since the cylinder 19 does not need to be made into a single part as in the past, the number of parts of the spray mechanism 16 can be reduced.
Furthermore, since it is not necessary to attach the spray mechanism 16 to the top plate 18 with adhesive or the like, the spray mechanism 16 can be easily assembled. Furthermore, in the above embodiment, the water suction pipe 20 is also integrally formed with the top plate 18, which also reduces the number of parts and simplifies the assembly work.

Although the above embodiment describes a steam iron having a switching valve, it is clear that the spray mechanism of the present invention can also be applied to an iron without a steam generation mechanism.

As mentioned above, in this invention, the cylinder that constitutes the spray mechanism for spraying the water in the water storage tank is integrally molded with the water storage tank, so the number of parts is reduced compared to the conventional spray mechanism in which the cylinder is a separate part. can be measured. Furthermore, since there is no need to watertightly attach the cylinder to the water storage tank with an adhesive or the like, the spray mechanism can be assembled more efficiently, which is extremely useful in practice.
