COOKING DEVICE FOR REINFORCING SAFETY

The present invention relates to a cooking apparatus with enhanced safety, and more particularly, to prevent foreign substances, such as soup, from entering the wires (or wires) at the lower end side of the tubular member connected to the sensing element that detects the temperature of a cooking vessel such as a pan. The present invention also relates to a cooking apparatus having enhanced safety that can ensure smooth lifting operation of a sensing element even when a case in which a lower end side wire of the tubular member is fixed.

In general, a cooking apparatus such as a gas range is capable of cooking food by burning LPG, LNG, or butane, etc., and is used as a kitchen appliance installed indoors or as a simple cooking utensil in outdoor camping.

The gas cooker is generally provided with an overheat prevention device. The overheat prevention device closely contacts a heat collecting member to a bottom surface of a cooking vessel placed on a cooking stand of a gas cooker, so that the sensing element senses heat conducted by the heat collecting member. In this case, the controller blocks the supply of gas to the gas range when the temperature is higher than the preset overheating reference temperature of the cooking vessel, thereby preventing the risk of overheating of the cooking vessel.

An example of the overheat prevention device for a gas range of the prior art will be described as follows.
