Knob igniter of a gas stove

Abstract

In a knob igniter used for a gas stove, a knob includes a switch module, a control unit, and a high-voltage coil, and a conducting wire is connected to an ignition electrode disposed on a stove mouth and corresponding to knob, such that the ignition electrode can produce a continuous discharge ignition. The knob of the present invention includes the separate switch module, control unit and high-voltage coil, and thus improving the life expectancy of the knob igniter. The invention has the advantages of simple structure, high ignition hit rate, and convenient installation, repair and maintenance, and replacement.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a component of a gas stove, and more particularly to a knob igniter of a gas stove.[0003]2. Description of the Related Art[0004]At present, most of the gas stoves available in the market adopt a high-voltage discharge ignition for an ignition regardless of indoor or outdoor applications, and the ignition device is mainly divided into piezoelectric ceramic igniters and pulse igniters. The piezoelectric ceramic igniter comprises a piezoelectric ceramic device, a hammer, a spring, an ignition electrode, a high-voltage wire, a turning plate, an ignition nozzle (or a pilot flame nozzle) and a shaft and a knob connected with the gas stove. In an operating process, the knob is turned to drive the shaft to turn the turning plate, and the turning plate drives the hammer to move backward and compress the spring. When the knob and the shaft are turned continuously, the channel for igniting the gas ...

AI Technical Summary

Benefits of technology

[0009]It is a primary objective of the present invention to overcome the shortcomings of the prior art by providing a knob igniter of a gas stove, and the knob igniter has the advantages of a high ignition hit rate, an easy repair and maintenance, and a separate discharge ignition by an ignition electrode to enhance the life expectancy of the igniter.

[0017]Compared with the prior art, the design of the switch module in accordance with the present invention assures the ignition hit rate. Since the knob installs separate control unit and high-voltage coil therein, only the ignition electrode connected to the knob through a conducting wire produces a high-voltage discharge for ignition, but the ignition electrodes of other unused stove mouths will not be ignited. Therefore, the invention can extend the life expectancy of the ignition electrodes and enhance the safety of their use. Regardless of installation, replacement or maintenance, the invention provides tremendous convenience.

Problems solved by technology

However, a gas stove set generally comes with a set of high-voltage coil and electronic component installed on the central control circuit for controlling the ignition, so that if a user turns on a knob of a gas stove having a plurality of stove mouths, not only a high-voltage discharge will be produced by that particular ignition electrode of the stove mouth, but the ignition electrodes of all other stove mouths will be started, and such arrangement seriously affect the life of the ignition electrodes.

Particularly for cooking, an overflow of liquid or steam will moisten the environment, and the ignition device of this sort will be moistened and damaged easily.

Furthermore, the igniter of this sort comes with a complicated structure and convenient repair, maintenance and replacement.
