Abstract

PROBLEM TO BE SOLVED: To rapidly supply heat from a heater to a heat-accumulating body and from the heat-accumulating body to a base and reduce decrease of temperature resulting from pressing clothes and improve the usability, by fixing a heat- accumulating body made of iron to the heater and burying it in the base, in the iron body. SOLUTION: When an iron body 28 is put on a placing seat 29 of a stand 27, electric currents are conducted to a heater 21 through the electrodes 30 of the stand 27, an electric supply pin 26 of the iron body 28, and a temperature control means. The heater 21 is heated by the currents and the heat heats the aluminum base 23 and simultaneously heats the heat-accumulating body 22. When the temperature of the base 23 reaches a preset temperature and a usable state, the iron body is removed from the stand 27 to press clothes by the iron. Then the temperature of the base decreases but the heat accumulated in the heat-accumulating body 22 is dissipated to the aluminum material constituting the base 23 to reduce the temperature decrease and keep the surface temperature at a constant temperature. Accordingly, the iron can be retained in a preset temperature for a long time.

The power supply pin contacts the electrode of a stand (not shown) to energize the heater 2. This constitutes a cordless iron that heats the base 1.

The operation of the above construction will be described. When the open / close stick 9 is pulled up by operating the steam button 11, the nozzle 10 is opened and the water in the water tank 8 is discharged from the vaporization chamber 3.
The steam generated in the vaporization chamber 3 is
Ironing is performed while supplying steam to clothing and the like by ejecting from the ejection holes 12 provided at the bottom of the iron.

[0006] In this case, if the ironing is continued for a long time in a state where the heater 2 is removed from the stand and the heater 2 is not energized, the temperature of the base 1 is reduced, steam is not generated, and the wrinkles of the fabric are hardly elongated.

As a means for compensating for this, the base 1
The temperature of the base 1 is increased, the heat is also supplied to the heat storage member 4 embedded in the base 1 to increase the heat capacity, and when the temperature of the base 1 is lowered, the heat is released from the heat storage member 4 so as to iron. I try to make it longer. The fins 7 are provided so that heat exchange between the base 1 and the heat storage member 4 can be performed quickly.

However, such a conventional configuration has the following problems. First, the fins 7 are provided to accelerate heat exchange with the heat storage member 4. However, the number of fins 7 is limited in terms of space.
When the space for providing is increased, the volume of the heat storage member 4 is reduced, and the total heat capacity is reduced.

In general, the heat storage member 4 is made of an inorganic material having a large specific heat or an organic material utilizing the latent heat of transition at the time of crystal transition. It was difficult to do it quickly.

In order to use such a compound as the heat storage member, the heat storage member 4 is sealed with the base lid 6. However, since a reliable sealing structure is required to ensure safety, the manufacturing method is required. There was a problem that was difficult.

An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide a cordless iron that is easy to manufacture and has a reduced temperature drop of the base due to ironing.

[0012]

According to the present invention, in order to achieve the above object, an iron heat storage element is fixed to a heater and buried in an aluminum base. In addition to the increase, the iron material and the heater are fixed and integrated, and the integrated heater and the iron heat storage body are cast into a base.

[0013] Thus, the heat can be quickly supplied from the heater to the heat storage element, and the heat supply from the heat storage element to the aluminum base can be rapidly performed. The ironing can be done easily by minimizing the temperature drop, and the iron heat storage element is cast into the base, so it is safe and
It is easy to manufacture.
