Description

[Detailed description of the invention] Industrial application field> The present invention mainly relates to a heating device that is placed on the plate of an electromagnetic range and used for boiling and cooking.
Although it is mainly used in general households, there are no particular restrictions on where it can be used.

<Prior art> In conventionally known pots and frying pans for electromagnetic ovens, the main body of the container is made of iron material (Ol), which is a heating element, as shown in a partial diagram in Figure 3 of the attached drawing. After that, a porcelain material was applied as a rust preventive material (02) to both the inside and outside of the container and fired again, resulting in a so-called three-layered container.

<Problems to be Solved by the Invention> However, with such conventional products, cracks tend to occur in the inner and outer porcelain layers when used for a long period of time. There were disadvantages in that the MS component was easily contaminated and the @ separation phenomenon was likely to occur. Also, fl! It also tends to peel off due to collision with objects, and is expensive due to problems in the manufacturing process.

Therefore, the inventor of the present invention aimed to eliminate the drawbacks of such conventional products.
This invention has developed a heating container for boiling and cooking such as a pot for an electromagnetic range, a pot for an electromagnetic range, and a kettle, which hardly causes any peeling phenomenon, and which is easy to manufacture and provide to the market at low cost.

The technical solution is to mix iron particles into a thermosetting synthetic resin, heat-resistant polymer, heat-resistant glass, or ceramic material, and use this iron particle-containing material. It is designed to be molded into a heating 4F container, and the weight ratio of iron particles in this material is 30.
This is the container and chichino in which it is mixed at a rate of ~95 fs.

〈Accordingly, iron particles are used as magnetic heating elements when used in electromagnetic ranges, and the reason why they are mixed into the material is because of the role of the iron particles as a connecting material and the formation of a solid as a compact. It's for a reason. However, the higher the proportion of iron particles mixed in the above-mentioned material, the better the heat generation performance will be, but even if Synthetic 1, which has a small specific gravity, is a fat, if the proportion of iron particles exceeds 95 parts by weight, it will not be suitable for use as a connecting material. It was found that the collision resistance becomes low and dangerous as the proportion of

In addition, if the proportion of iron particles mixed in is less than 30 parts by weight, the heat generation performance of the container for an electromagnetic range will deteriorate and it will take a long time to boil and cook, making it a practical problem. It turns out.

In this way, we decided to set the mixing ratio of iron particles to the range (1) above, but within the range of this 9-car limit, we took into consideration the nature of the material to be mixed. Set the amount and form.

The shaped heating container is placed on the plate of an electromagnetic range and used for boiling and cooking.

<Effects of the Invention> The heating container molded as described in 2 is extremely easy to manufacture, and when a synthetic resin material is used, a commonly used synthetic resin molding machine can be used. , even if glass or ceramic materials are used, the 91 standard for heat-resistant glass containers and ceramics, which is commonly practiced, is not recommended. L
It has the remarkable advantage that it can be manufactured very easily using similar means.

Example 1 (Example 1) The diagram shown in Figure 1 shows the use of melamine resin (elamine resin), which is one of the thermosetting synthetic resin materials.
Using a synthetic resin injection molding machine as the material to be mixed with iron particles! ! 1. This shows the left hand part (1). As shown in FIG. 2, this hand I1% (1) has a structure in which melamine resin (2) connects iron particles (3) in a transparent manner. Iron particles (3
) is molded so that it does not protrude from the surface.

The grip part (1) is made of 1°000g of melamine resin.
It was molded using a mixture of iron sand, ooog, and iron sand in a weight ratio of 1 to 8.

The melamine resin can be molded relatively easily and has particularly excellent heat resistance, water resistance, and mechanical strength.

The mixing ratio of iron particles is approximately 7% by weight in the case of synthetic taro, since its specific gravity is small and it is relatively highly active.
Even if about 0=, 851 g is mixed, a container with sufficient hardness can be obtained.

However, even if a minimum of 60 parts to a maximum of 95 parts are mixed, sufficient durability is exhibited as a heating container for an electromagnetic range.

(Example 2) Borosilicate as a heat-resistant glass material
ilicaLe glass) material 2.000g, iron sand 31000w! A cylindrical vortex was formed from the materials mixed at i amount ratio.

In this case as well, a pot that could be fully used as an electromagnetic microwave pot was obtained.

Lead as a heat-resistant glass material
ss) A cylindrical container was also formed using a material obtained by mixing iron sand in the same ratio as above, and in this case as well, a container that could withstand practical use was obtained.

In the case of a glass material, it is preferable to mix iron particles at a mixing ratio of 40 to 60 parts by weight, but it may be about 70 parts.

(Example 3) Material 3 made of clay mixed with some kaolinite, feldspar, and quartz
,000g/)3. A so-called clay pot was molded by hand using a material mixed with OOh iron spheres with a diameter of 1111/#, and the pot was coated with paint on both the front and back sides and fired.

It was fired without any particular cracks.

I used the second generation as a pot for an electromagnetic range, and it generated enough heat to be used for boiling and cooking.

In the case of this clay pot, the weight ratio of the material to the iron particles is 40.
Although it is preferable to mix in the range of 60 parts to 60 parts, it has been found that a certain level of heat generation can be obtained even with a minimum of 30 parts.

The case where three kinds of materials were used as an example has been described in detail above, but the thermosetting synthetic resins referred to in the present invention include urea resin, 7-enol oil, epoxy resin, unsaturated polyester resin, alkyd resin, and urethane resin. Typical examples of heat-resistant polymers include aromatic polyamides, polyimides, polybenzimigsol, metal chelate polymers, and heptan resins. Polyethylene can also be used. Although expensive, quartz glass can also be used as a heat-resistant glass material.

However, it is not intended to be limited to these materials, and any other material that can achieve the purpose of the present invention and that satisfies the constituent requirements is the technical scope of the present invention (1). ) shall be understood as belonging to section 1.
