Description

[Detailed Description of the Invention] Industrial field of application The present invention is an apparatus suitable for holding and heating an externally heated trowel, which retains and takes out a heated trowel and loses heat after use. It is related to a heater that is convenient for reheating.

Conventional technology and its problems Most of the conventional technology has a built-in heating device.
This is compact and convenient in terms of heating, but for occupations that require the use of a trowel at all times, such as those involved in cleaning and wiener sausage production, the extra weight of the heater and battery Since it is added, it is too heavy to hold, there is a risk of electric shock when used in a place where water is handled, there is another inconvenience such as being unable to wash with water when dirty.

Therefore, I thought about using a lightweight trowel without a built-in heating device, but unexpectedly workability, that is, heating,
No heating appliances are found that are easy to hold, insert or remove.

Means for Solving the Problems There are no particular restrictions on the trowel to be heated by the heater of the present invention. For example, when using a rod-shaped soldering iron or a scissors-shaped hair styling iron, the design of the heater may be appropriately changed for each type of the iron.

The present invention is basically composed of a lid plate, a base plate, and a connecting body, and a space for holding an iron is provided between the lid plate and the base plate.

The lid and base are made of a material with good thermal conductivity, such as an aluminum plate inside (the side where the two plates face each other is the inside, the other side is the outside. The same applies below), and the heat insulating material is the outside. It is practical to use a two-layer structure of nito. The outer shape does not necessarily have to be a disk shape, and may be any shape, for example, a rectangular plate shape. In addition, one or both of the lid and the pedestal, which have good thermal conductivity, include a heating device.
For example, a cartridge heater is embedded. Depending on the case, a thermostat may be embedded and the heating temperature may be adjusted. The diameter of the base should be larger than the diameter of the base, and the outer edge of the base should be outside all edges of the base. However, instead of providing such a large or small diameter, the outer edge portion of the lid plate may be tapered to widen the space between the outer edge portions between the two plates.

Both boards are connected by a unit, but there is a gap between both boards that can hold the trowel. This gap may be fixed, or in some cases the lid may be biased toward the base using a spring or the like so that the gap varies according to the variation in the thickness of the trowel. It may be so arranged that it is tightly held between the two boards. Even in such a case, it is convenient to leave a small gap at all times for the insertion of the trowel, so for example, a cylindrical wall integrated with the lid is slidably fitted to the wall of the connecting body. And so on.

It is also possible to keep the entire heater at a convenient position and height by suspending it from the ceiling by a suspension shaft. The suspension shaft is not necessarily rigid but may be somewhat flexible or twistable.

When using the heater of the present invention, first, electricity is supplied to heat the whole, and a predetermined temperature is maintained by a thermostat. A trowel that is to be used or once used and has radiated heat is inserted into this, and after a while, it is taken out and used.

The inside of both panels is made of a material with good thermal conductivity, so the heat generated by the heating device immediately spreads over the entire surface. Since the outside is a poorly heat-conductive conductor, there is little heat dissipation to the outside.

For the trowel held between the upper and lower plates, adjust the length of the trowel and the diameter of the base so that the center of gravity of the trowel is supported by the base, and the trowel will be held slightly loose. Also, it is possible to prevent an accident such as an accidental drop of the iron.

Embodiments Several embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a typical example of the present invention, which comprises a cover plate 1, a base plate 2, a connecting body 3 and a suspension shaft 4. The base 2 has a diameter larger than that of the lid 1, and the heating device 6 is attached to both the lid 1 and the base 2.

FIG. 3 shows another example of the present invention. The outer edge portion of the lid 1 is provided with a taper 9 to make the gap 8 wider by that amount, so that the take-out and insertion of the iron can be facilitated.

In FIG. 4, the cylindrical wall 11 is fixedly attached to the lid 1, and the cylindrical wall 11 is fitted inside the connecting body 3, while the lower part of the cylindrical wall 11 and the lower part of the base 2 are connected by the spring 10. They are connected, and the contraction force urges the lid 1 toward the base 2. Further, the one shown in FIG. 5 is obtained by partially modifying the one shown in FIG. That is, the lid 1 is suspended from the suspension shaft 4 and the spring 10.
The cylindrical side wall 13 is fitted to the outer side of the suspension shaft 4 and the connecting body 3, and the lid plate 1 is attached to the base plate 2 by the repulsive force of the spring 10.
It is biased to the side, and the stopper 14 can ensure a minimum gap. In addition, in order to take out the lead wires for the heating device 6 and the thermostat 7 to the outside of the heater, a lead hole 12 for electric wire is provided inside the connecting body 3 and the suspension shaft 4.

Effect Since the present invention heater has the above-mentioned structure, it has various effects. For example, the heating of the lid and base can be performed quickly. In addition, the heat can be quickly transmitted to the iron, and since the outside of both panels is made of heat insulating material, there is little loss due to radiation of heat and accidents that may cause burns by touching the hand are prevented. Yes, it has a simple structure and can be manufactured at low cost.
Insertion / removal of the iron can be done smoothly, and there are few unexpected dropouts.
