Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a temperature control device for irons used in general households. 〇Conventional structure and problems thereof The structure of a general iron has a thermostat installed on the base. Star
At the same time, the base is covered with an all-metal cover, and a handle made of a thermosetting resin with excellent heat resistance, such as phenol resin, is attached.

However, since the limited color of phenolic resin is not acceptable to users, iron handles have been arbitrarily colored by painting or the like. Therefore, in order to provide irons at low prices.

Materials that do not require painting and can be colored arbitrarily, i.e. 1
It is an easy idea to make the handle entirely of thermoplastic resin. In this case, thermoplastic resins generally have poorer heat resistance than thermosetting resins, and conventional metal covers cannot be used for appliances with high-temperature parts, such as irons, unless expensive materials are used. , the intended purpose is not achieved.

What we came up with was an iron like the one shown in Figure 1, with thermostat 2 on base 1? At the same time, the upper surface of the base 1 is covered with a cover 3 made of thermosetting resin, and a handle 4 made of thermoplastic resin is attached above the cover 3.

The thermostat 2 is linked to a temperature control member 5 rotatably pivoted to the handle 4 through an operating rod 6, and can be moved up and down by a cam provided on the temperature control member 6 to set a desired temperature. It is configured so that it can be done.

However, due to the unique characteristics of thermoplastic resin, the cover 3 of the handle 4 is made of thermosetting resin, which has poorer thermal conductivity than metal, and the heat of the base 1, which is heated to a high temperature, is moderated to some extent, making it difficult to put into practical use. Although the degree of strength obtained is guaranteed,
Expansion and contraction occur along with the heating part of the iron. Therefore, the temperature adjustment member 5 linked to the thermostout 2 also changes slightly along with the handle 4, making it impossible to accurately and stably adjust the temperature.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks and provides an iron that is inexpensive and allows stable temperature control.

Structure of the Invention In order to achieve all of the above-mentioned objects, the present invention has a thermostat mounted on a base, a thermosetting resin cup mounted above the base covering the thermostat, and a thermoplastic resin mounted on the cover. Equipped with a handle made of resin and a temperature control member linked to the thermostat - By attaching the temperature control member to the entire cover, accurate and stable temperature control can be performed without being affected by thermal expansion and contraction of the handle. This is what I did.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In the figure, 10 is the base, 11 is the thermos cloth y fixed on the base 10), 12 (is the thermos cloth 1)
This cover is attached above the base 10 and is made of thermosetting resin such as phenol resin. 1
3. A handle fixed on the cigarette cup (-12 at multiple places with screws 14, etc.) 1 made of thermoplastic resin such as PP. 15 is a removable tank in front of the handle 13, and 16 is a It is a temperature control member rotatably attached to the cover 12, and the temperature control member rotates vertically.

- It has a cam surface 17'z that causes the entire rotation. 18 has one end in contact with the metal on the cam surface, and the other end in contact with the thermos...
Manual operation using the temperature control member 16 is performed using the operating rod linked to the thermostat 12 via the operating rod 18.
The temperature is then adjusted to the desired temperature.

The temperature control member 16 is supported by the cover 12 at a stepped portion 19 and is attached to sandwich the cover 12 with metal fittings 20 and other fastening members, so that even if the handle 13 is deformed by heat or external pressure, it will have an adverse effect on temperature control. I have nothing to give.

Note that the cover 12 has a protrusion 2 in the space 21 inside the handle 13.
2? If the temperature adjusting members 16 are provided and fixed, overheating of the temperature adjusting members 16 can be prevented.

- Also, the protrusion 22 may extend at or near the surface of the iron.

In short, it is sufficient that the temperature regulating member is fixed to a cover made of thermosetting resin so as not to be adversely affected by deformation of the handle made of thermoplastic resin.

Effects of the Invention As described above, the present invention provides stable temperature control without being adversely affected by heat by attaching the temperature control member to the cup (-) made of thermosetting resin. Resin-based irons have the power to make use of the features of thermoplastic resins, such as coloring, weight reduction, excellent workability, etc., in irons.
