Description

  The present invention relates to a ceramic cooking appliance equipped with a carbon molded body, and more specifically, a carbon molded body produced by compression molding a carbon material such as charcoal or graphite is mounted on the bottom surface, and a gas range and an induction range. The present invention relates to a ceramic cooking appliance equipped with a carbon molded body that can be used without being classified as (electromagnetic cooker / IH cooker).

  In general, cooking utensils, frying pans and various pots used in kitchens are made of metal materials such as iron, stainless steel and aluminum. And the bottom is formed as a structure in which the upper part of the instrument main body, which is flat and widely formed, is widely opened and the handle is connected to the side surface as necessary.

  Recently, these cooking utensils require not only basic conditions for cooking food to be cooked such as durability, corrosion resistance and heat resistance, but also functional aspects for cooking more deliciously. Is also an important factor. For these reasons, it has been considered to improve the taste of an object to be cooked using an active ingredient released from the material itself, in addition to using a metal material which has been a main material. In addition, various functional materials such as ceramics, single minerals, mixed minerals, tempered glass, and carbon materials are used as materials for cooking utensils in order to obtain quick cooking and heat retention due to endothermic effect, antibacterial effect, health promotion effect, etc. Yes.

  Among them, cooking utensils using heat-resistant ceramic ceramics made by firing non-metallic inorganic solid materials at high temperatures are excellent in fire resistance, heat resistance, hardness, chemical resistance, and do not rot or rust, so they are hygienic. It is frequently used as a non-toxic product.

  These heat-resistant ceramic cooking utensils are usually molded into a container and baked, then applied with a glaze to enhance the surface properties, and then fired again to ensure that the glaze penetrates the molded product surface evenly. While giving gloss, it is possible to improve the strength and make it glossy so that it is not contaminated by foreign substances. In addition, the inner surface of the container is thinly coated with a fluororesin so that food and drink are not burnt and are easy to clean.

  On the other hand, an electric stove and a gas range are usually used as a heat source in a heat-resistant ceramic cooking utensil. In the case of the induction range, the operating principle is that a current is generated by sending a current to the coil on the upper plate of the range, and the magnetic field is heated by a resistance component when passing through the bottom of the cooking utensil on the upper plate. Suppose that That is, in the induction range, an eddy current is generated by using an iron component, and induction heating is performed. Therefore, induction heating is performed by including an iron (Fe) component having magnetism in a portion in contact with the grill of the induction range, that is, the bottom of the cooking utensil at least.

  Thus, in the case of a heat-resistant ceramic cooking utensil, it can be used in an induction range by attaching a magnetic body to the bottom. However, in this case, the effect of the heat-resistant ceramic is not halved, but the expansion coefficient of the magnetic iron metal is different from that of the heat-resistant ceramic of the appliance body. Since the utensil main body may be cracked, there has been almost no production of such a complex cooking utensil.

Therefore, research is progressing so that heat-resistant ceramic cooking utensils can be used by induction heating in the induction range, and at the same time, can also be used for electric stoves and general gas ranges. It's real.
nothing special

  Therefore, the present invention has been devised to solve the above-described problems, and by incorporating a carbon molded body produced by compression molding a carbon material inside the bottom surface of the container portion, induction is achieved. The object is to provide a ceramic cooking appliance equipped with a carbon molded body that can be used not only in a range but also in a gas range.

In order to achieve the above-mentioned object, the present invention is designed so that an inorganic material is molded into a container shape and fired at a high temperature, and is made in close contact with the heat resistant ceramic material body 10 and the bottom surface of the body 10. The carbon molded body 20 positioned and formed by compression molding a carbon material, and a fixture 30 made of a heat-resistant ceramic material for attaching the carbon molded body 20 to the bottom of the instrument body 10 by a predetermined attachment means. It is characterized by.
The attachment between the fixture 30 and the instrument main body 10 can be performed by applying a glaze to the attachment portion of the fixture 30 and bonding it to the instrument main body 10 and then baking it again at a high temperature.
In addition, the heat resistant ceramic material body 10 made by molding an inorganic material into a container shape and firing at high temperature, is positioned so as to be in close contact with the bottom surface of the material body 10, and is produced by compression molding a carbon material. The carbon molded body 20 and the space 31 into which the carbon molded body 20 is inserted, and the upper surface of the carbon molded body 20 is fixed by a predetermined attaching means along the edge of the lower surface of the instrument body 10. 30.
The fixing tool 30 can be formed such that the carbon molded body 20 that is inserted into the through hole 32 is exposed to the outside when the seat portion is opened.

In the ceramic cooking appliance to which the carbon molded body configured as described above is attached, the carbon molded body 20 that is in close contact with the bottom surface of the appliance body 10 is used without being distinguished between the gas range and the induction range in the kitchen equipment. .
The carbon molded body 20 itself is fixed and fixed by the fixing tool 30 bonded by high-temperature firing with glaze, so that the carbon molded body 20 is not separated or dropped from the instrument body 10 due to external impact, vibration or the like. Since the carbon molded body 20 obtained by compression-molding a carbon material and the appliance main body 10 made of a heat-resistant ceramic material have similar thermal expansion coefficients, they are similarly expanded or contracted during heating or cooling, and are not cracked or broken.

  As described above, the ceramic cooking appliance equipped with the carbon molded body 20 of the present invention is heated not only by the heating wire of the induction range but also by the flame of the gas range. Can be used. Moreover, it is possible to improve the heat storage property with respect to the heat source through the carbon molded body 20 and prevent the phenomenon that the food to be cooked is burnt even locally. Further, since the carbon molded body 20 has a thermal expansion coefficient almost similar to that of the heat-resistant ceramic material constituting the instrument body 10, the instrument body 10 may be cracked or damaged during heating even if it is inserted therein. Can also be prevented. Furthermore, the use of the light carbon molded body 20 has the effect of significantly reducing the weight of the instrument and facilitating the handling of the user.

  Hereinafter, the present invention will be described in detail with reference to embodiments illustrated in the accompanying drawings. However, the present invention is not limited to the embodiments illustrated in the drawings. In addition, among the cooking utensils to which the present invention is applied, the description will be made with reference to a pot as a representative. However, the present invention is not limited to a pot, but other than that, a pot, a frying pan, a yakiniku plate Obviously, it can be applied to other cooking utensils.

  FIG. 1 is an exploded perspective view showing a cooking utensil according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of the cooking utensil of FIG.

  As shown in the figure, the present invention is a device body 10 formed by molding an inorganic material and firing at a high temperature, a carbon molded body 20 formed by compression molding a carbon material, and the carbon molded body. It is comprised with the fixing tool 30 attached to the lower end of the instrument main body 10 in the state which inserted 20.

  First, the appliance main body 10 is made of a heat-resistant ceramic ceramic produced by molding it into a shape of a cooking appliance to be produced using a non-metallic inorganic solid material and firing it at a high temperature. These ceramic ceramics are usually baked and then coated with a glaze to reinforce the surface properties and fired again to improve surface gloss and strength.

  These heat-resistant ceramic ceramics are superior in fire resistance, heat resistance, hardness, and chemical resistance compared to conventional aluminum or stainless steel cooking utensils, and are hygienic and non-toxic because they do not rot or rust. Is well known.

  At the same time, although not shown in the drawing on the inner surface of the appliance main body 10, the fluororesin is thinly coated so that foods and drinks to be cooked do not burn and are easy to clean. It has become.

  The carbon molded body 20 is a carbon material such as charcoal or graphite produced in a plate shape by a compression molding method, and its shape corresponds to the seat surface of the instrument body 10 to be applied. Usually, since the seat part surface of the instrument main body 10 is a round shape, it is desirable to use the carbon molded body 20 that is manufactured in a round shape as seen from the plane.

  The carbon molded body 20 is positioned so as to be in close contact with the bottom surface of the lower end of the instrument body 10, that is, by being accommodated in a holding wall 11 formed integrally with the instrument body 10 so as to be surrounded by the bottom periphery. In this way, when used in the induction range, an eddy current is generated and induction heating is performed without the configuration of another resistance component (iron). It is considered that this is because the carbon molded body 20 plays a role of a resistor only in the heat-resistant ceramic ceramic that is the material of the instrument body 10 and generates an eddy current.

  In addition, since the carbon molded body 20 is substantially similar in thermal expansion coefficient to the heat-resistant ceramic material constituting the instrument body 10, the instrument body 10 is cracked or damaged during heating even if inserted into the holding wall 11. Can be prevented.

  At the same time, since the carbon molded body 20 has thermal conductivity with respect to a flame which is a heat supply source of the gas range, it can be easily used for an electric stove and a gas range. The heat transmitted to the inside of the appliance body 10 is temporarily stored in the carbon molded body 20 and then transmitted from the carbon molded body 20, so that the heat storage is improved and the phenomenon that the cooked food is locally burned is prevented. it can.

  The fixing tool 30 is used as a means for fixing the carbon molded body 20 in close contact with the bottom surface of the instrument body 10. The illustrated fixture 30 is formed in a disk shape, and is disposed in a stacked manner with the carbon molded body 20 on the bottom surface of the carbon molded body 20 stored in the holding wall 11, and is similarly stored in the holding wall 11. Is done. The peripheral edge of the fixture 30 is attached along the inner peripheral surface of the holding wall 11 by a predetermined attaching means.

  Such a fixture 30 is preferably made of a heat-resistant ceramic material, which is the same material as that of the instrument body 10, and a heat-resistant adhesive can usually be used for adhesion between the fixture 30 and the instrument body 10. More preferably, after applying a glaze to the attachment portion of the fixture 30 and bonding it to the instrument body 10, it is fired again at a high temperature so as to have a strong bonding force.

  3 is an exploded perspective view showing a cooking utensil according to another embodiment of the present invention, and FIG. 4 is a bottom perspective view of the cooking utensil of FIG.

  As shown in this figure, as another embodiment of the present invention, an instrument body 10 produced by molding an inorganic material and firing at a high temperature, and a carbon molded article produced by compression molding a carbon material. 20 and a fixture 30 attached to the lower end of the instrument body 10 with the carbon molded body 20 inserted. The fixing tool 30 has a through-hole 32 penetrating through the bottom thereof, and the carbon molded body 20 inserted therein is exposed to the outside.

  The fixture 30 itself in this embodiment is formed in a ring shape that is substantially L-shaped in cross section forming the space 31. Then, with the carbon molded body 20 supported inside, the upper edge surface is attached to the peripheral edge of the bottom surface of the instrument body 10 by, for example, a strong binding force due to a glaze that is fired at a high temperature.

  The carbon molded body 20 is exposed to the outside through the through-hole 32 in the fixture 30 so as to be in direct contact with the heat source of the induction range or the microwave oven. If it carries out like this, the speed of the heat transmitted to the inside of the apparatus main body 10 can be made still faster, cooking time can be shortened, and the deodorizing and sterilizing effect which is the characteristic of charcoal will be exhibited, and the bad smell generated during cooking is removed. It will have additional effects such as.

  As described above, the heat-resistant ceramic cooking utensil of the present invention is heated not only by the heating wire of the induction range but also by the flame of the gas range by mounting the carbon molding 20 on the bottom thereof. For this reason, since two ranges having different heating modes can be used together, it is possible to solve the troubles and cost problems that must be provided for each type of instrument when both the gas range and the induction range are used. Furthermore, an iron component can be additionally contained when the carbon molded body 20 is manufactured in order to increase the thermal conductivity with respect to the induction range.

  In addition, the cooking utensil according to the present invention improves the heat storage performance with respect to the heat source through the carbon molded body 20 and can prevent the phenomenon that the food to be cooked locally burns. Moreover, since the carbon molded body 20 has a thermal expansion coefficient substantially similar to that of the heat-resistant ceramic material constituting the instrument body 10, the instrument body 10 is cracked or damaged when heated even if it is inserted therein. This can be prevented, and by using the light carbon molded body 20, the weight feeling of the instrument is remarkably reduced and the handling of the user is facilitated.

  At the same time, various papers and conventional techniques that the carbon material, which is the component of the carbon molded body 20, has effects such as deodorization, sterilization, mold prevention, far-infrared effect, maintenance of appropriate temperature and humidity, and removal of malodors. It has been proved by this and will have such an effect.
