Safety controller of gas stove

Abstract

A safety controller includes a housing including a base and a cover. The base has a main member with a chamber therein, an input channel, an output channel, a gas channel, a check port between the gas channel and the chamber, a lid member with an open end communicated with the chamber. A support member is provided in the chamber. A film resides between the lid member and the cover to separate a space into an inner pressure room and an outer pressure room. A control device is provided in the chamber with an end connected to the film to control a flow rate of gas flowing to the gas channel from the chamber. A pressure up electromagnetic valve and an exhaust electromagnetic valve are provided beside the cover to be activated to change pressures in the inner and outer pressure room respectively to make the film deforming.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to a gas stove, and more particularly to a safety controller of a gas stove.[0003]2. Description of the Related Art[0004]Conventional stoves using gas as the fuel are classified into gas stove, baking stove, and heating stove, and so on. To increase the safety of these stoves, there are two types of designs for safety. One of which provides a control unit to shut off the stove when the stove is overheating or exceeding a setting time. The second of which provides a structure to prevent the stove from being lit directly by the gas switch. These two designs have many inventions.[0005]Both of the conventional safety designs for stove have to change the current structure of the gas stove that increases the cost and lower the profit. In addition, the conventional gas stoves usually control gas supplying to the burner by a gas switch. However, conventional gas switches cannot control ga...

AI Technical Summary

Benefits of technology

[0006]The primary objective of the present invention is to provide a safety controller of a gas stove, which increases the safety of the gas stove without having to change the structure.

[0007]The secondary objective of the present invention is to provide a safety controller of a gas stove, which can control the gas of greater flow rate.

Problems solved by technology

Both of the conventional safety designs for stove have to change the current structure of the gas stove that increases the cost and lower the profit.

However, conventional gas switches cannot control gas of big flow rate (such as 100,000 btu or more natural gas) that limit the application of the conventional gas stoves.
