Abstract

PURPOSE:To make it possible to completely decompose smoke generated at the time of heating and to reduce smoke at the time of cooking by forming a heat resisting film containing an oxidation catalyst such as hydrocarbon or the like on the surface of a metal base material which is a secondary radiant body. CONSTITUTION:A metal base material of a steel-shape or a plate-shape having an opening is used as a secondary radiant body is employed, and a heat resisting film containing an oxidation catalyst such as hydrocarbon or the like is formed on the surface of the metal base material. As an oxidation catalyst a composite metallic oxide having a provskite structure of ABO3 is used. Smoke generated at the time of cooking almost contains an unsaturated fatty acid of 18C and a mixture thereof. At portion of the secondary radiant bode of the grill having a temperature close to 1,000 deg.C, the smoke is cut into 1C-3C, and completely oxidized by the oxidation catalyst, whereby purification of the smoke can be carried out. In order to sufficiently achieve the function of the oxidation catalyst, a paint essentially composed of an organic SiC polymer is used as a binder. When the paint is sintered at a temperature of 600 deg.C or more, the film of SiC produced is extremely porous and excellent in heat resistance, and hence thermal deterioration of the metal base material which is used as a can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a grill used for cooking grilled foods.

Conventional configurations and their problems Conventional grills that use gas as a heat source have two configurations: one in which food is heated by the radiant light of the combustion flame of a burner, and the other in which the burner heats a secondary radiant and heat is emitted from the secondary radiant. There are some that heat with radiant light. Although each of the four methods has its merits, there is a major problem in that a large amount of smoke is generated when fish etc. are heated.

This is an unavoidable problem because the fats and oils contained in the food are not completely decomposed, and depending on the location of the grill in the kitchen, the kitchen may become full of smoke or other undesirable conditions. .

Purpose of the Invention In order to solve these conventional problems, it is an object of the present invention to completely decompose smoke generated during heating in a cooking grill having a secondary width agent body, thereby reducing smoke during cooking. It is an object.

Structure of the Invention In order to achieve this object, the present invention forms a heat-resistant coating containing an oxidation catalyst such as a hydrocarbon on the surface of a metal base material that is a secondary radiator.

DESCRIPTION OF EMBODIMENTS As an oxidation catalyst, a metal composite oxide having a 117 gunukite structure of AB Os is used.
This is because it is sufficiently stable even at high temperatures close to C and has high oxidizing activity for hydrogen ashing and the like. For example, A site is La
, La1-zSrXCOo8 (x-0,
In 2), the first part is about the oxidation of Co, CH4, and CaHs.
It is known that something like this is shown in the figure.

In Fig. 1, 1 is La0.8SrO02Co'Oa,
2 is the reaction rate of complete oxidation of 1% Pd/5i02.3 is 1% Pt/A120a at each temperature. From now on 1
It can be seen that a0.8Sro, zCoOa has superior oxidation activity compared to noble metal supported catalysts. Most of the smoke generated when adjusting Jq1 is a mixture of fats and oils such as 018 oleic acid, lylinic acid, and linoleic acid, and their incomplete oxides.
These are cut into 01 to C8 at the high temperature part of the secondary radiator. This ClN03 minute is L a o, s S r O,2
It becomes possible to purify smoke by completely oxidizing it with Coma. In order to make full use of the function of such an oxidation catalyst, a heat-resistant film containing an oxidation catalyst dispersed is formed on the surface of a metal base material, which is a secondary medium, and the binder used at this time is organic SiC. Paints based on polymers are suitable. The SiC polymer referred to here is the following A (with rosiloxane polymer as the structural unit, S
It is a mixture of six-membered rings, six-membered rings, and ten-membered rings consisting of i, B, and O. The thermogravimetric change of this is shown in Figure 2, and 6
There is no weight change at temperatures above 00°C, which means that if sintered at temperatures above 600°C, only the skeleton of 1 5l-C- 1 will be formed. The resulting SiC film is very porous and suitable for dispersing particles with oxidizing activity such as La0.8Sr0.2COC8.

It also has excellent heat resistance and has the effect of preventing rain from degrading the underlying metal base material due to heat.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, the present invention is to form a heat-resistant film containing an oxidation catalyst such as hydrogen ash on the surface of a metal base material that is a secondary radiator of a grill, which is generated during cooking. It can oxidize and decompose smoke, and its catalyst, an ABOa type metal composite oxide, has excellent heat control properties and can withstand use at high temperatures. Furthermore, the SiC film itself has excellent heat resistance.
Since most of the material is , it has the effect of preventing deterioration of the underlying metal base due to heat.
