Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a steam iron for general household use.

Conventional structure and its problems Conventionally, in this type of steam iron, as shown in Fig. 1, 1 is a base with a built-in heater 2, and the base 1 includes a vaporizing chamber 3 and a vaporizing chamber that covers the vaporizing chamber 3. It is provided with a chamber lid 4 and a first steam passage 5, a steam outlet 6 is provided on the ironing surface of the base 1, and a base lid 7 is attached and detached by tightening with screws or the like. Further, a space is provided between the base lid γ and the base 1, and the first steam passage 5 is connected to the base lid γ.
It was common to have a second steam passage 8 communicating with the steam outlet 6. However, in the above configuration, if the performance of the steam ejection amount and ejection time deteriorates during ironing work, if the base M7 is removed from the base 1, the steam ejection port 6, the first steam passage 6 and the second steam Although the passage 8 could be cleaned, it was not possible to clean the inside of the vaporization chamber 3, where water scale was most deposited. Here, as a method to make it possible to clean the inside of the vaporization chamber, it was considered to provide an opening lid for the vaporization chamber on the side of the ironing base, but the opening lid from which water drips has a heater. There was a problem that the vaporization ability decreased and hot water spewed out because the heat was not transferred sufficiently to the base. Further, the ironing base 1 has a base lid 7 on the surface, and when ironing, a step is formed on the surface. Furthermore, since the base lid, which is a separate part, is tightened, the ironing of the base 1 with the built-in heater 2 is done with a low temperature, and the ironing temperature is low and the temperature distribution over the entire surface is uniform. In addition, the temperature force S at the IT+ part of the ironing surface, which is particularly important for ironing, becomes low, which causes problems such as poor ironing effect.

OBJECTS OF THE INVENTION The present invention solves these conventional problems, makes it easier to clean the vaporization chamber and the steam passage, and improves the workability of attaching and detaching the IZ chamber lid. It provides:

Structure of the invention), *Uh. 7K, I. 7□, Kay, -~6 Base, the vaporization chamber lid that covers the vaporization chamber, and the vaporization chamber.''
- a water passage member installed in the water passage member, a heat insulating member disposed close to the water passage member, and a water tank removably provided above the heat insulating member; , a heat insulating member is integrally provided and is detachable from above the base, and the vaporization chamber cover and the water passage member,
Since the heat insulating member is integrated and can be attached and removed from above the base, even when the base and vaporizing chamber lid are hot after ironing, you can easily remove the vaporizing chamber cover by holding the handle of the heat insulating member. It can be attached and detached, and it is easy to clean water scales in the vaporization chamber and steam passage, improving work efficiency.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 2 and 3, 11 is a base having a heater 12, and this base 11 is provided with a vaporization chamber 13. 14 is a steam outlet, which is connected to the vaporizing chamber 13 through a steam passage 15. Reference numeral 16 denotes a vaporization chamber lid that covers the vaporization chamber 13 and steam passage 15 and is fastened to the base 11 with screws or the like. Reference numeral 17 denotes a second vaporizing chamber cover which forms a part of the vaporizing chamber cover 16 and is detachably provided via a packing 18 made of an elastic material such as a comb. The second vaporization chamber M17 includes a vaporization chamber 13.
A water passage 19 made of metal or ceramic and serving as a water passage member communicating with the water passage, and a heat insulating plate 20 made of a resin material or the like serving as a heat insulating member are integrally provided. The second vaporization chamber lid 17 is made of a resin material or the like that uses a protrusion 21 provided on a part of the integrated heat insulating plate 20 as a heat insulating member of a cover 22 that covers the upper surface of the base 711 made of metal or the like. It is fixed by a movable fixed plate 24 provided on the configured second heat insulating plate 23. Reference numeral 25 denotes an elastic paulownia material made of a spring material or the like that biases the movable fixed plate 24 and securely fixes the second vaporization chamber 17. Above the vaporization chamber 13, a water tank 26 is detachably provided.
A drip nozzle 27 is provided at the bottom of the water pump 26.
It is equipped with

The dripping nozzle 27 passes through a nozzle packing 28 made of a resin material, rubber, etc., and serves as a water passage member.
It communicates with the nozzle 19 mentioned above. Dripping from the water tank 26 is controlled by a drip control button 2 protruding above the water tank 26.
9.

To explain the operation in the above configuration, when steam is generated and ironing is performed, water scale accumulates in the vaporizing chamber 13, which adversely affects the amount and time of steam ejection, and the accumulated water scale If steam is ejected from the steam outlet 14, immediately remove it from the water tank 2.
6 from the iron body, and with the iron placed horizontally, operate the movable fixing plate 24 to release the fixation of the second vaporizing chamber cover 17, and then remove it by holding the protrusion 21 provided on the heat insulating plate 20. The heat insulating plate 24 is close to one of the water tanks 26 and the outside air and does not easily reach high temperatures, so it can be attached and detached even when the second vaporization chamber M17 is hot. After removing the second vaporizing chamber lid 1a, the vaporizing chamber 13 and the steam passage 15 can be easily cleaned from above the iron main body. Further, since no separate member is provided on the ironing surface, there is no difference in level and the temperature distribution is uniform, which has the effect of improving the finishing effect of ironing.

FIG. 4 shows another embodiment of the present invention, in which a heat insulating board 30 and a water passage 31 are integrally constructed. With this structure, water leakage that occurs between the water passage and the heat insulating board 30 can be prevented. .

FIG. 5 shows another embodiment of the present invention, in which the water passage 3
A deionizer device 33 made of ion exchange resin or the like is installed inside the evaporator 2. With this configuration, the water supplied to the vaporization chamber can be purified and impurities mixed in the water can also be filtered. This has the effect of reducing the amount of water scale that accumulates in the vaporization chamber, allowing for even longer use.

Effects of the Invention By integrating the water passage member provided on one side of the vaporizing chamber lid and the heat insulating member, even when the vaporizing chamber cover is hot after ironing, by lifting the heat insulating member, Made it possible to put on and take off.

Therefore, the workability of cleaning the vaporizing chamber and the steam passage can also be improved.
