Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an iron that uses a heat storage material to suppress a drop in the temperature of the base.

Conventional structure and its problems In recent years, a heat storage material is housed in a storage chamber provided in the base of an iron, suppressing the drop in temperature of the vaporizing chamber when applying water droplets to the vaporizing chamber, and causing water droplets to eject from the base surface. to prevent or
Alternatively, an iron has been developed that improves operability by disconnecting the power supply during ironing work.

In particular, as a heat storage material for irons, although it is not publicly known, as a result of our investigation, a material based on pentaerythritol is most suitable in terms of heat generation amount, heat storage temperature, etc. Furthermore, while general heat storage materials utilize latent heat of melting and vaporization, heat storage materials based on pentaerythritol utilize transition latent heat, and when used in total, they have a solid 11 crystal structure. Since it only changes, it is generally very easy to handle, and a simple structure such as an open state is sufficient as a housing structure for the heat storage material.

However, in the event of abnormal heating in which the heat storage temperature exceeds the melting point due to a malfunction of the temperature controller, etc. when heating the heat storage material, the open housing structure described above does not allow the heat storage material to escape from the heat storage material storage chamber. A phenomenon of leakage occurs, and the heat storage material that leaks out while the iron is being operated may cause burns or stain the clothes being ironed, which is a drawback in terms of safety.

OBJECTS OF THE INVENTION In view of the above-mentioned drawbacks, the present invention provides an iron that does not pose a safety problem even if the heat storage material melts and is excellent in mass production.

Structure of the Invention In order to achieve this object, the iron of the present invention has a heat storage container that is sealed with a heat storage material mainly made of an organic substance, and one heat storage container is attached to a base. With this configuration, even if the heat storage material melts due to abnormal heating,
Safety is improved because the heat storage material does not leak out of the iron body.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a partial sectional view of an iron according to an embodiment of the present invention, and FIG. 2 is a plan view of the base of the iron. In the figure, 1 is a heat storage container made of a metal with good thermal conductivity, and inside is a heat storage material 2 made of an organic material mainly composed of an organic substance such as pentaerythyl IJ) and mixed with a stabilizer as an additive. is sealed. 3 is the base,
A plurality of storage chambers 4 into which the heat storage containers 1 are inserted are formed on this upper surface. 6 is a fixing plate that holds down the heat storage container 1 so that it does not come out from the storage chamber 4. A heater embedded in the six-piece base 3 is used to heat the heat storage container 1, the heat storage container 2, and the base 3. This is a cover that covers the top surface of the 7Vi base 3, and a handle 8 is attached to the top.

Further, a temperature adjustment lever 9 is provided in the raw part of the handle 8,
It is connected to a temperature controller (not shown) and is used to set the temperature of the base 3. 1o is a power supply terminal to which a power cord is connected to supply power to the heater 6.

The operation of the iron configured as above will be explained below.

First, a power cord (not shown) is connected to the power supply terminal 10, and when the temperature control lever 9 is set to the set temperature and the power is turned on, the heat storage container 1, heat storage material 2, and base 3 are heated by the heater 6 to the set temperature. A temperature regulator maintains that temperature. At this time, the heat storage material 2 stores thermal energy.

Now, when ironing is performed, the power coat is removed from the power supply terminal 1o and used without the power cord. Therefore, there is no need to worry about the power cord getting tangled in the way of ironing. During ironing, the heat storage material 2 releases the thermal energy stored inside, so the drop in temperature of the base 3 is suppressed and ironing can be carried out for a long time.

As described above, in normal operation, there is no need to seal the heat storage material 2ij with the heat storage container 1. However, as mentioned above, in the process where the heat storage material 2 is heated to the set temperature and maintained at that temperature by the temperature controller, if the heat storage material 2 is heated above the melting point 1 due to a malfunction of the temperature controller, etc. Since the heat storage material 2 is in a liquid state, if the heat storage material 2 is not sealed by the heat storage container 1, the heat storage material 2 will leak from the storage chamber 4 and will be discharged as a hot liquid 11 to the outside of the iron main body. This can cause burns to people and stain the clothes being ironed. However, since the heat storage material 2 is sealed by the heat storage container 1, even if the heat storage material 2 melts and becomes liquid, the heat storage material 2 will not be discharged to the outside of the iron main body, so it is safe.

1. By sealing the heat storage material 2, it is possible to isolate the heat storage material 2 from the air, suppressing the oxidation of the organic substance that is the main material of the heat storage material 2, making the heat storage material 2 more stable, and further increasing its durability. can be improved.

Furthermore, the heat storage container 1 is separately installed from the heat storage material 2Y″i base 3.
Since it is configured to be sealed and attached to the base 3, the heat storage material 2
can be made into a unit and can be assembled by simply inserting the heat storage container 1 into the storage chamber 4 provided in the base 3, which facilitates manufacturing.

In this embodiment, the shape of the heat storage container 1 is a rectangular parallelepiped, but the shape can be freely changed, for example, it can be made into a cylindrical shape for ease of manufacture, or it can be made into a cylindrical shape to improve the filling efficiency of the heat storage container 1 into the base 3. It may be shaped like a hexagonal column, etc., and the main point is storage chamber 4.
The shape makes it easy to insert into the body. Furthermore, in this embodiment, one heat storage container 1 is inserted into one storage chamber 4C, but a large number of heat storage containers 1 may be inserted into one storage chamber 4. It is sufficient if the heat storage container 1 can be accommodated in the container 4.

The heat storage container 1 does not have many stages as in the embodiment, but only one V.
It can also be strained.

Further, in this embodiment, the heat storage material 2 is simply sealed with the heat storage container 1, but if the internal air of the heat storage container 1 is replaced with an inert gas, pentaerythritol, which is the main material of the heat storage material 2, etc. It is possible to further suppress the oxidation of the organic substances and improve the durability of the heat storage material 2.

As described above, the iron of the present invention has the advantages of Pentaeris'J
) - By attaching a sealed heat storage container containing a heat storage material mainly made of organic substances such as iron to the base surface, even if the heat storage material melts due to abnormal heating, the heat storage material will not leak out of the iron body. Therefore, it can be used without causing burns or staining clothes while ironing due to heat storage material leaking. Also,
In the present invention, the heat storage phase can be sealed in the heat storage container in a separate process, so it can be manufactured efficiently without using special jigs.Furthermore, by unitizing the heat storage material, it has excellent mass productivity. . In this way, its practical effects can be seen as a dog.
