Benefits of technology

The technical problem of this patent is to improve the gas cooking device by controlling the temperature more conveniently and overcoming the defects of the prior art.

Problems solved by technology

For the existing gas cooking device, such as a gas stove, as long as gas is continuously supplied, a temperature of a cookware heated by the gas cooking device can continue to rise, and it is difficult to control the heated temperature within a certain reasonable range, and a flame size can only be modulated by manually adjusting a valve size of the gas stove.
However, such adjustment method has a certain hysteresis, i.e., when a user realizes that the flame size is too large, the food has been superheated and cooked to a certain extent, resulting in loss of food nutrition and even coking.
Moreover, during the whole cooking process, the user needs to constantly adjust the valve size of the gas valve according to the needs of cooking stages, thus causing frequent operations and many inconveniences in use.

embodiment 1

[0047]As shown in FIG. 1, the present invention relates to a gas cooking device, such as a gas stove, etc. The gas cooking device comprises a gas stove 2 and a cooking utensil 1 arranged above the gas stove 2. The cooking utensil is preferably a cookware 1. The gas stove 2 comprises a burner 21, a furnace frame 22, a panel 23, a gas feed tube 25, and a control valve 24. The panel 27 is provided with an installation hole, the burner 21 is arranged in the installation hole, the furnace frame 22 is arranged on the panel 23, and the furnace frame 22 and the burner 21 are arranged as concentric circles, i.e., the furnace frame 22 is arranged at a periphery of the burner 21 to support an object to be heated. The gas feed tube 25 is communicated with the burner 21 to provide a tube for gas supply, the gas feed tube 25 is provided with the control valve 24, and the control valve 24 can be an electromagnetic valve or other valves with a function of adjusting a gas flow. The gas cooking devic...

embodiment 2

[0065]As shown in FIG. 3, the present embodiment improves the temperature control layer 11 on the basis the Embodiment 1. In the present embodiment, the temperature control layer 11 exists independently of the cookware instead of being arranged on the cookware 1. Specifically, a support plate is arranged above the furnace frame 22, and the support plate is placed on the furnace frame 22. As another preferred embodiment, the support plate can also be integrated with or fixedly connected to the furnace frame 22, the temperature control layer not only is made into a sheet, but also can be made of a powdery or granular precision alloy material or iron-nickel alloy material, and is attached to the support plate. Certainly, in the Embodiment 1, the temperature control layer can also be made of the powdery or granular precision alloy material or iron-nickel alloy material, and is attached to a bottom of the cookware.

[0066]In addition, the temperature control layer can also be arranged on a...

Abstract

A gas cooking device comprises a burner, a gas feed tube, a control valve used to control a gas flow, an electromagnetic generating device capable of generating an electromagnetic signal, and a control unit capable of controlling an opening size of the control valve according to the electromagnetic signal. The control valve and the electromagnetic generating device are electrically connected to the control unit respectively. By employing the control valve, the control unit, and the electromagnetic generating device, control of a flame size of the gas cooking device can be realized.
