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 water drops into the vaporizing chamber, and causing water droplets to eject from the base surface. Irons have been developed that improve operability by preventing such problems or by disconnecting the power supply during ironing operations.

In particular, as a heat storage material for irons, although it is not publicly known, we have investigated it and found that Pentaerythritol is suitable in terms of heat storage amount, heat storage temperature, etc.
The most suitable material is Furthermore, while general heat storage materials utilize the latent heat of melting or vaporization, the heat storage material based on pentaerythritol utilizes transition latent heat, and during normal use it remains solid and has a crystalline structure. Since only changes,
Generally, it is 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, where the temperature of the heat storage material 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 there is a risk of burns caused by the leaked heat storage material while the iron is being operated, or staining the clothes being ironed, which is a drawback in terms of safety.

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

Structure of the Invention To achieve this object, the iron of the present invention includes a base having a heater with a plurality of storage chambers formed therein, and a plurality of heat storage containers in which a heat storage material mainly composed of an organic substance is sealed. With this configuration, even if the heat storage material melts due to abnormal heating, the heat storage material will not leak out of the iron main body, improving safety.

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 a base portion of the iron. In the figure, 1 is a heat storage container made of a metal or the like with good thermal conductivity, and inside it is sealed a heat storage material 2 made of an organic material mainly composed of an organic substance such as pentaerythritol and mixed with a stabilizer as an additive. There is. Reference numeral 3 denotes a base, and a plurality of storage chambers 4 into which heat storage containers 1 are inserted are formed on the upper surface of the base. 5 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 6 is embedded in the base 3 and is used to heat the heat storage container 1, the heat storage material 2, and the base 3. Reference numeral 7 denotes a cover that covers the upper surface of the base 3, and a handle 8 is attached to the upper part of this cover. Further, a temperature control lever 9 is provided on the upper part of the handle 8, and is connected to a temperature control device not shown in the figure, and is used to set the temperature of the base 3. Reference numeral 10 denotes 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, connect the power cord (not shown) to the power supply terminal 10.
When the temperature control lever 9 is adjusted to the set temperature and the power is turned on, the heat storage container 1, heat storage material 2, and base 3 are heated to the set temperature by the heater 6, and the temperature is maintained by the temperature controller. At this time, the heat storage material 2 stores thermal energy.

Now, when ironing is performed, the power cord is removed from the power supply terminal 10 and used without the power cord. Therefore, the power cord does not become tangled and become a nuisance during ironing. During ironing, the heat storage material 2 releases the thermal energy stored inside, so the temperature drop of the base 3 is suppressed and ironing can be carried out for a long time.

As described above, in normal operation, the heat storage material 2 does not need to be sealed by the heat storage container 1. However, as mentioned above, during the process in which the heat storage material 2 is heated to the set temperature and the temperature is maintained by the temperature controller, the heat storage material 2
When heated to above its melting point, the heat storage material 2 becomes liquid, so 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 go outside the iron body. The hot liquid is discharged, causing burns to the user and staining 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.

In addition, by sealing the heat storage material 2, the heat storage material 2 can be isolated from the air, suppressing 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 increasing its durability. It can be improved further.

Furthermore, since the heat storage material 2 is sealed in the heat storage container 1 and attached to the base 3 separately from the base 3, the heat storage material 2 can be made into a unit, and a storage chamber 4 in which the heat storage container 1 is provided in the base 3 can be used. It is easy to manufacture because it can be assembled by simply inserting it into the holder.

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 in the shape of a hexagonal column or the like, and in short, the shape may be such that it can be easily inserted into the storage chamber 4. Furthermore, in this embodiment, one heat storage container 1 is inserted into one storage chamber 4, 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. Further, the number of heat storage containers 1 may not be provided in large numbers as in the embodiment, but only one.

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

Effects of the Invention As described above, the iron of the present invention forms a plurality of storage chambers in the base having a heater, and
By installing a plurality of sealed heat storage containers containing heat storage materials made mainly of organic substances in this storage chamber, even if the heat storage materials melt due to abnormal heating, the heat storage materials will not leak out of the iron body. Since there is no heat storage material, it can be used without causing burns or staining the clothes being ironed due to heat storage material leaking. In addition, in the present invention, since the heat storage material can be sealed in the heat storage container in a separate process, it can be manufactured efficiently without using special jigs.
By unitizing the heat storage material, mass production is also possible. As described above, its practical effects are significant.
