[0030] figure 1 is a perspective view of a heating cooking appliance according to the present invention. figure 2 is an exploded perspective view of a heating cooking appliance according to the present invention.

[0031] refer to figure 1 with figure 2 , the heating cooking appliance according to the present invention includes a casing 2 protecting the lower part of the main body to form the appearance of the lower part of the cooking appliance and having an open upper side, a ceramic plate 1 mounted on the upper side of the casing 2, and a cover The top frame 3 of the peripheral part of the ceramic board 1 . In addition, additional external features of the heating cooking appliance include an exhaust grill 13 formed at the rear of the cooking appliance for discharging burned gas, and an on / off switch for gas burning formed at the approximate front of the ceramic plate 1 Controlled switch 14. Although the position and shape of the exhaust grill 13 and the switch 14 v...

[0080] Figure 11 is a cross-sectional view of a nozzle according to another embodiment of the present invention. To change the configuration of the nozzle discharge member according to another embodiment of the present invention, other components are the same as those in the first embodiment, and the same symbols denote the same components and no specific explanation thereof is given.

[0081] Such as Figure 11 As shown, the nozzle 17 includes a circular flow guide 154 , wherein the outer surface of the discharge member 156 is circular in order to facilitate a smoother flow of air by virtue of the momentum of the gas as it exits the discharge hole 155 .

[0082]In the circular flow guide 154, the diameter of the discharge piece 156 does not change abruptly, but rounds off smoothly along the direction of air flow. Therefore, the air flows smoothly along with the gas flow in the gas discharge direction.

[0083] Although the inlet of the flow guide 154 is not circular and t...

Abstract

A heating cooking appliance and a burner system of the same are provided. The heating cooking appliance includes a case, a plate that covers the case, a burner system under the plate, and an exhaust unit at a side of the plate. The burner system includes a burner pot providing a mixing space in which gas and air are uniformly mixed, a mixing tube through which the gas and air are supplied into the burner pot, and a nozzle maintained a predetermined distance from a mixing tube unit. A discharger of the nozzle is reduced in diameter. A discharging hole of the nozzle is formed to have a length / diameter ratio of 0.9 to 1.1. A venturi marking a boundary between a convergence and a divergence with respect to the diameter of the mixing tube is disposed at a middle part when the mixing tube is divided into three equal parts.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2006-0130612 filed Dec. 20, 2006, with U.S. Patent Classification Nos. 35 U.S.C. 119 and 35 U.S.C. 365, which are hereby incorporated by reference in their entirety In this article. technical field [0003] The invention relates to a heating cooking appliance, in particular to a heating cooking appliance and a burner system thereof. The burner system can reduce the size of the cooking appliance while maintaining high combustion efficiency and reducing airflow resistance. Background technique [0004] A heating cooker is a device used to heat and cook food. The present invention is particularly directed to a gas cooking range for heating and cooking food by burning gas to generate heat. Such gas cooking hobs using hot plates (also known as 'hobs') are increasingly used. [0005] Gas cooking hobs that operate by gas combustion include a burner syst...
