Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a stove device for home or business use.

(Prior art) In the conventional stove device shown in Fig. 1, when a fire occurs in a burner, a heating plate made of an iron plate or heat-resistant glass is heated, and the food to be cooked in a pot or the like on the plate is heated. This is the configuration to do it.

(Problems with the prior art) This conventional stove device has the disadvantage that it heats not only the heating plate directly above the burner, but also the surrounding area.To eliminate this disadvantage, there is a means to move the burner closer to the heating plate. However, in that case, there was a problem in that incomplete combustion occurred and CO was generated. The present invention provides a stove device that eliminates such conventional problems, improves heating efficiency, stabilizes combustion, and promotes oxidation reaction.

(Means for Solving the Problems) A burner is installed in a heating chamber, a catalyst peripheral wall is formed around the outer periphery of the burner, and a combustion chamber surrounded by the catalyst peripheral wall is configured above the burner, A heating plate on which cooking utensils such as pots are placed is installed above the combustion chamber.

(Function) A fire occurring in the combustion chamber is prevented from spreading by the catalyst surrounding wall and directly heats the heating plate. Therefore, the area around the heating plate is not overheated, and the catalyst surrounding wall is heated at the same time, but since the catalyst surrounding wall is also a highly radiant body, radiant heat is applied to the heating plate to further heat the heating plate. Furthermore, since the combustion chamber is surrounded by the catalyst peripheral wall, the oxidation reaction is promoted, and the flame within the combustion chamber can be significantly stabilized.

(Example) Reference numeral 1 denotes a heating chamber, and a burner 2 is installed inside this heating chamber 1. A catalyst peripheral wall 3 is formed on the outer periphery of the burner 2, and a combustion chamber 9 surrounded by the catalyst peripheral wall 3 is configured in the upper part of the burner. A heating plate 4 on which cooking utensils are placed is installed. Reference numeral 5 is a filling made of a heat insulating material, and 7 is a gas/air premixture introduction pipe. The burner 2 and heating plate 4 may be made of ceramic.

(Operation) In this configuration, a premixture of gas and air is introduced into the burner 2 via the premixture introduction pipe 7, and combustion is started. The heating plate 4 is heated by the combustion heat generated by the combustion, and the catalyst peripheral wall 3 is also heated at the same time. Since the catalyst surrounding wall 3 is also a highly radiant body, it gives radiant heat to the heating plate 4 to further heat the heating plate 4. In addition, such a catalyst peripheral wall 3
Since the presence of the heating plate 4 prevents the spread of fire, the heating plate 4 is directly heated.
The surrounding area of the catalyst can avoid heating and the oxidation reaction can be further promoted by the catalyst surrounding wall 3, and together with this, being surrounded by the catalyst surrounding wall 3 makes the flame much more stable. It can also lead to The exhaust gas passes through the catalyst peripheral wall 3 itself and is discharged from the exhaust section 8. By carrying out such combustion, the thermal efficiency directly above the burner can be improved by 5% compared to the conventional method, and the CO concentration in the exhaust gas can be suppressed to 10 ppm or less.

(Effects of the invention) As described above, this invention prevents the spread of fire, avoids overheating around the heating plate, further improves heating efficiency, stabilizes combustion, and minimizes the discharge of unburned parts. This is an excellent effect that can be avoided.
