COOKING VESSEL AND MANUFACTURING METHOD THEREOF

The present invention relates to a cooking vessel and a manufacturing method thereof, and more particularly, to a cooking vessel excellent in wear resistance and a manufacturing method thereof.

In the past, cooking utensils or cooking vessels have been used to cook food or to contain cooked foods, which are made of copper, tin, silver, brass or iron, made of metal and dried After glazing, the surface is glazed and baked in a kiln at a temperature of 1300 ~ 1450 ℃, and wood-carved wood.

In recent years, the development of metal cooking containers that can save the energy and intrinsic taste and nutrition while saving energy in consideration of thermal efficiency has been actively developed. However, cooking vessels are often exposed to high humidity and high temperature, the metal container had a problem that corrosion easily occurs.

To solve this problem of corrosion, various coatings have been applied to the surface of the container. Ceramic coating, Teflon coating, etc. were mainly used, but there was a problem in that the strength is easily worn or broken. Therefore, it was difficult to prevent corrosion of the container for a long time.

Therefore, there is a demand for developing a cooking vessel having a low material cost and excellent wear resistance and corrosion resistance.

The problem to be solved by the present invention is to provide a cooking vessel excellent in wear resistance and corrosion resistance and a method of manufacturing the same.

The cooking container according to an embodiment of the present invention includes a container body having a space formed therein, and an anodizing oxide layer formed on the surface of the container body.

Here, the container body is made of one metal selected from the group consisting of Al, Mg, Zn, Ti, Ta, Hf, Nb, alloys thereof and clad metal, and the anodizing oxide layer is Al, Mg, Zn, Ti. , Ta, Hf, Nb, and may be formed of one oxide selected from the group consisting of oxides of these alloys.

In addition, the method may further include a magnetic layer formed between the container body and the anodizing oxide layer or on the anodizing oxide layer and formed of a material having magnetic properties.

In addition, the above-described anodizing oxide layer may be formed to have a Mohs hardness of 90 or more.

In addition, the cooking vessel according to an embodiment of the present invention may further include a coating layer formed to cover the anodizing oxide layer.

On the other hand, the cooking vessel manufacturing method according to an embodiment of the present invention is a metal selected from the group consisting of Al, Mg, Zn, Ti, Ta, Hf, Nb, alloys thereof and clad metal (Clad metal) therein Forming a bottom surface and a side to have a space and forming the container body, and anodizing the surface of the container body to form an anodizing oxide layer.

The method may further include forming a magnetic layer by spraying a magnetic material and applying a coating material on the anodizing oxide layer or the magnetic layer to form a coating layer.

According to an embodiment of the present invention, a dense anodizing oxide layer is formed on the surface of the cooking vessel. Therefore, a cooking container excellent in wear resistance and corrosion resistance can be obtained. In addition, the anodizing oxide layer has a high adsorption force. Therefore, when a coating is formed on an oxide layer, high bearing force with respect to a coating layer can be obtained, and the coating layer which is hard to peel off can be formed. In addition, it may include a magnetic layer while enhancing the wear resistance, it is possible to use in a heating device using a magnetic force, which is used a lot recently. On the other hand, since the anodizing oxide layer has a high wear resistance and a beautiful surface in itself, it is possible to obtain a cooking vessel of excellent quality even without painting on the outside. Therefore, it is not necessary to use a coating or coating layer that is not good for the body.

In addition, according to an embodiment of the present invention, the manufacturing process is simple, there is an advantage that can lower the manufacturing cost of the cooking vessel.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Like parts are designated by like reference numerals throughout the specification.

1 and 2, the features of the cooking vessel according to the embodiments of the present invention will be described.

1 is a perspective view of a cooking vessel 100 according to a first embodiment of the present invention, the enlarged circle of Figure 1 is an enlarged view showing an enlarged cross section of the cooking vessel. The thickness of the oxide layer 103 is considerably thinner than that of the container body 101 in order not to consider the relative size of the thickness in order to exhibit normality or characteristics.

Referring to FIG. 1, the cooking vessel 100 according to the first embodiment of the present invention includes a container body 101, an anodizing oxide layer 103, and a coating layer 105.

The container body 101 has side and bottom surfaces, and a space for storing food therein is formed. In the embodiments of the present invention will be described using a container body 101 of a general shape of a circular bottom, the container body 101 may be formed in various shapes, it is not a main feature of the present invention. The container body 101 is formed of one metal selected from the group consisting of Al, Mg, Zn, Ti, Ta, Hf, Nb, alloys thereof and clad metal, and an oxide layer directly from the container body 101. 103 can be formed. Clad metal is an alloy that combines a variety of metals together to take only the advantages of each metal, in the present invention it can be used to join the aluminum plate and stainless steel plate with clad metal. In addition, a brass coating comprising a clad metal layer made of an aluminum layer and a stainless layer, an blasting surface formed on the surface of the stainless layer by blasting with an abrasive made of a high carbon steel material, and a copper spray layer formed on the blasting surface. Clad metal made can be used.

The anodizing oxide layer 103 is positioned on the container body 101 so as to cover all of the container body 101. Anodizing oxide layer 103 is formed through an anodization method. Anodization is a method of oxidizing the surface of an object by using oxygen generated from the anode by electrolyzing the object to be anodized by placing it on the anode and dipping it in an electrolytic material. The anodizing oxide layer 103 according to the embodiment of the present invention is formed to have a Mohs hardness of 90 or more using anodization. However, if a soft oxide layer is required as needed, the anodizing oxide layer 103 may be formed to have a lower strength by changing the conditions of anodization. The oxide layer 103 is formed directly from the container body 101 in consideration of economical efficiency. Therefore, it is formed of an oxide layer of the same metal as the container body 101. However, an oxide layer may be formed by joining a container body and a separate metal, in which case Al, Mg, Zn, Ti, Ta, Hf, Nb, and one metal selected from the group consisting of oxides of their alloys are used. To form an oxide. These metals are not only easy to form oxides, but also excellent in wear resistance and corrosion resistance of the formed oxides, and are suitable for use in cooking containers.

The coating layer 105 is formed on the anodizing oxide layer 103. The coating layer 105 is to make the cooking vessel more beautiful, it may be formed in a brilliant color. In addition, the outside and the inside of the container body 101 may be formed of different materials. Since the anodizing oxide layer 103 has a rougher surface than metal, the coating layer 105 may be more strongly bonded. Therefore, the coating layer 105 hard to peel off can be formed.

Next, the cooking vessel 200 according to the second embodiment of the present invention will be described with reference to FIG. 2.

The cooking vessel 200 according to the second embodiment of the present invention includes a container body 201, an anodizing oxide layer 201, a magnetic layer 207, and a coating layer 205. The container body 201, the anodizing oxide layer 201, and the coating layer 205 are the same as those described in the first embodiment, and thus description thereof is omitted here.

The magnetic layer 207 is located between the anodizing oxide layer 203 and the coating layer 205. The magnetic layer 207 is formed of a magnetic material, for example, iron and an alloy thereof, to impart magnetism to the cooking vessel 200. Recently, many heating apparatuses for heating a heating object using a change of magnetic force without a flame have been used. However, stainless steel, which is widely used as a material for cooking vessels due to corrosion, had no magnetic properties and was difficult to use. However, in the case of the cooking vessel 200 according to the embodiment of the present invention, the oxide layer 203 and the magnetic layer 207 are simultaneously included. Therefore, while having high wear resistance, it can be used as it is in induction apparatus. The magnetic layer 207 can be formed by spraying a metal having magnetic properties. In addition, the magnetic layer may be located between the container body 201 and the oxide layer 203 according to the order or need of the manufacturing method.

Hereinafter, a method of manufacturing a cooking container according to an embodiment of the present invention will be described with reference to FIGS. 3 and 4 simultaneously.

First, a base material which is a material constituting the container body 101 is prepared (401). As the base material, the container body 101 may use one metal selected from the group consisting of Al, Mg, Zn, Ti, Ta, Hf, Nb, alloys thereof, and clad metal. Here, the clad metal may be used as well as the clad metal coated with brass as well as the general clad metal as described in the first embodiment.

Next, the prepared base material is shape | molded (301, 402). Since molding uses a general method of molding a metal sheet, the description thereof is omitted here.

Next, the molded body 101 is pretreated and anodized for anodization (302, 403). Since the pretreatment method is the same as the conventional method, its detailed description is omitted here. The anodic oxidation method uses an electrolyte having a lactic acid concentration of 15 to 20 (wt%) by the lactic acid (sulfuric acid method), and the positive electrode is used as the container body 101. The voltage of electrolysis is DC 13 ~ 25V. However, in order to form a harder oxide layer 103, a voltage of 40 V or more may be applied to the electrolysis. The oxide layer 103 is formed through the anodic oxidation method (405). However, to form an oxide layer 103 of a different material from the container body 101, an oxide layer 103 of another material is formed by using a metal film formed of Al, Mg, Zn, Ti, Ta, Hf, Nb, or an alloy thereof. ) Can be formed. In this case, the container body 101 should not be caused to flow current so that the container body 101 is not oxidized.

Next, the coating layer 105 is formed on the formed oxide layer 103 (303,407). The coating layer 105 is formed by spraying or thermal spraying. However, it can be formed in various ways as needed. In addition, it can be formed in a variety of colors that can make use of the aesthetics, the color of the inside and outside of the container can be set differently.

On the other hand, if the magnetic layer is to be further formed, forming a magnetic layer between the step of forming the base material 301 and the anodizing step 302 or between the anodizing step 302 and the coating layer forming step 303 It may further include (305). Iron is used as a metal for forming the magnetic layer, and the magnetic layer is formed by a method such as thermal spraying or sputtering. However, if necessary, it can be formed through various methods. When the magnetic layer is formed between the step 301 of forming the base material and the anodizing step 302, the metal for forming the oxide layer may be further applied or contacted on the magnetic layer in order to more easily form the oxide layer 103. . The spraying method can be used as a method of metal coating.
