Description

Ceramics handle combined structure < RTI ID = 0.0 >

The present invention relates to a porcelain knob coupling structure, and more particularly, to a porcelain knob having a handle coupled to a cooking cavity made of a metal through a simple joining structure, so that the knob of a porcelain material can be easily fixed to the cooking cavity, The present invention relates to a pottery knob coupling structure which can be firmly fixed even for a long period of use to prolong the durability life.

Further, the present invention relates to a pottery knob coupling structure which not only provides a hygienic effect over a conventional joining method but also has an excellent appearance of a product and can prevent the shape and color of the knob from being deformed even when used for a long time during cooking.

Cooking utensils such as pots are generally used to boil, fry, boil, and roast food. The structure of the cooking vessel is largely composed of a main body having a receiving portion capable of containing food and a lid capable of covering the main body, and a handle is provided on an outer surface of the main body and the lid of the cooking vessel, It is configured to catch the cookware.

Conventional cooking vessel knobs are mainly made of only metal materials, those made of metallic materials such as bakelite, melamine, or silicon molded products, and those having relatively low thermal conductivity.

Such a cooking container provided with a conventional handle is shown in Registration Practical Utility Model No. 20-0350330 (hereinafter referred to as Patent Document 1). Patent Document 1 relates to a handle of a heating cooker and a fastening hole 2b formed on one side of a fastening plate 2 made of metal is formed on a fastening hole 1a formed on one side of a handle body 1 made of a heat resistant resin And the other end of the adhesive layer 5 coated on the exposed surface 2c of the fastening plate 2 is fastened to the fastening portion 2a formed on the other side of the fastening plate 2 and fastened by the fastening bolt 4, Sensitive coloring epoxy resin layer 7 is formed on the surface of the color print layer 6. In this case,

In addition, in the cooking utensil holding handle 10, the handle 10 is constituted by an upper frame 12 and a lower frame 18 (see Japanese Patent Application Laid-Open No. 20-0288135 And the upper frame 12 is molded of ABS resin or polycarbonate, and the lower frame 18 is molded of phenol resin.

However, the above-mentioned Patent Documents 1 and 2 have a merit that the thermal conductivity is relatively low, but when used for a long time, the heat resistant resin such as silicon and plastic is deformed and melted or damaged due to the thermal power of the gas stove.

In addition, the cooking container handle made of only a metal material has a high thermal conductivity at the time of cooking, so there is a fear of burn when the handle is hot and the handle is heated by the bare hand because the heat is conducted the most. The handle made of wood material has a high price, If the coating is not well coated, moisture is penetrated during the washing of the cookware, causing a problem of rotting, and it is easily deformed when cooked with strong thermal power, resulting in black marks and bad appearance.

On the other hand, ceramics is a collective term for ceramics and porcelain. It is made by blending feldspar or quartz with china clay or fine clay as a main raw material, (Cured), and is generally characterized by being baked at a high temperature, whitened and light-transmitting, sufficiently baked to have no absorbent property, and high mechanical strength.

Therefore, when the handle is manufactured using the above-described ceramics as a raw material and is coupled to the cooking vessel, the shape and color do not change even when used for a long time, so that it is convenient to manage and has a low thermal conductivity. It is suitable to be used in combination with the container body.

However, as can be seen in Patent Documents 1 and 2, most of the conventional cooking vessel knobs are directly connected to the cooking vessel body by welding, riveting or bolt. When the knob is applied to a handle made of a ceramic material, There is a problem that it is difficult to fix the coupling part to the cooking device of the metal material by being damaged and loosened.
