Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a steam iron capable of cleaning limescale adhering to a vaporization chamber, a steam passageway, a steam hole, etc. provided in a steam iron body.

Conventional structure and its problems Conventionally, in steam irons that instantly vaporize water dripping from a water tank in a vaporization chamber and directly eject it from the steam hole, after long periods of use, the vaporization chamber and steam There was limescale adhering to the passageways, and even during ironing, the limescale was discharged from the steam holes along with the steam, staining the fabrics.

In addition, the accumulated limescale causes clogging of steam passages, steam holes, etc., and reduces ironing efficiency, such as the steam not stopping during use. As a means to solve the above problems, irons have been commercialized that have a lid on the bottom of the base, which can be disassembled with screws and can be cleaned at will, but in this case, tools are required. In addition, there are accidents such as not being able to disassemble due to seizing of screws, etc., and even if disassembled, the vaporization chamber, especially at the point where water drips, cannot be cleaned, and only a partial cleaning can be done. was not able to respond. Purpose of the Invention The present invention has been made to solve the above-mentioned conventional problems, and provides a unit pump device that can clean limescale with a simple configuration by applying water vaporization energy instead of using mechanical methods. The purpose is to provide a steam iron with

Structure of the Invention In order to achieve the above object, the present invention is a unit pump device which is detachably attached to an iron body, and has a pump part with elastic recovery at one end and a cylindrical member connecting a vaporization chamber and a water tank at the other end. By having a structure with removably connectable cylindrical parts, the base surface can be used, for example, when the base surface is dry and energized at a high temperature, water is forcibly fed into the vaporization chamber using a unit pump device provided as an accessory. The steam pressure produced by the sudden and large amount of steam generation is used to wash away limescale adhering to the vaporizing chamber etc. through the steam holes.

Description of examples Embodiments of the present invention will be described below with reference to the accompanying drawings.

As a unit pump device, which is the only point of the present invention, several shapes can be considered as shown in Fig. 5, but in particular, in Fig. Since it is composed of a section 10a and a piston section 10b, it is 2.
It requires twice the volume, making it larger and making it difficult to operate with one hand.

Therefore, it can be said that the one shown in Figure 5A is suitable for compactly organizing the contents. Furthermore, since these can stand on their own as accessory parts, they are ideal in relation to the center of gravity of the part that stores water. Next, an embodiment of the steam iron as a whole will be described with reference to FIGS. 1 to 4.

In the figure, reference numeral 1 denotes a base in which a heater 2 is embedded, and which has a vaporizing chamber 3, a steam passage 4, and a steam hole 5, and is fixed to the iron main body A. Reference numeral 6 denotes a water tank, which is detachable from the base and has a drip nozzle 7 at its bottom.

A cylindrical member 8 connects the dripping nozzle 7 and the vaporization chamber 3, and is processed by closing the upper surface with silicone rubber or the like.

Reference numeral 9 denotes a cylindrical portion, to which a pump portion 10 made of elastically resilient material such as rubber and having a flat portion a or b at one end is connected, and both constitute a unit pump device.

In the above configuration, when cleaning limescale from various parts of the base 1 of the iron, remove the water tank 6, first compress the elastically restoring pump part 10 of the unit pump device, then release your hand, suck water into the pump part 10, and then After inserting the cylindrical portion 9 into the cylindrical portion 8 of the iron main body, the pump portion 10 is compressed again to instantly pump a large amount of water into the vaporization chamber 3.
The water in the vaporization chamber 3 and limescale adhering to the vaporization chamber 3, the steam passage 4, the steam hole 5, etc. are discharged by the evaporation energy, allowing cleaning.

Since the water in the resilient pump section 10 is forced out, all the steam generated in the vaporization chamber 3 flows toward the steam hole 5 without backflowing. Figure 6 A shows the storage state of the unit pump device when not in use;
, b. Effects of the Invention As is clear from the above embodiments, the present invention is capable of removing scales attached to various parts of the base by operating a unit pump device that is simply assembled as a separate part from the iron body with one hand. Moreover, it has a simple structure and can be provided at low cost.
