Gas Range

摘要

A gas range including a main valve and an auxiliary valve, providing a weak fire power by blocking some of gas flow paths, when a cooking container reaches a setting temperature, by the auxiliary valve so as to let the rice stand after cooking or simmer the ingredients to prepare stock for a long time, and blocking gas supply by closing the main valve when the cooking container becomes in an overheated state so as to prevent an accident by overheat.

主权项

1. A gas range used for cooking comprising:
a housing mounted inside a gas range case and having a gas flow path which includes an inflow path, an outflow path, first and second connection paths for connecting the inflow path and the outflow path with each other, and an auxiliary flow path; an operation lever mounted on a front face of the case, actuating a main valve and an auxiliary valve to supply gas through the gas flow path for cooking, the operation lever being adapted to ignite spark through a burner valve and an ignition device; the main valve comprising:
a first pin moving according to operation of the operation lever and returning to its original position by a first spring;a first opening valve moving according to a movement of the first pin and returning to its original position by a second spring;a first cutoff plate mounted for opening and closing the inflow path according to a movement of the first opening valve;a first thermoelectric couple mounted near to flame for generating an electromotive force by the flame; anda first magnet magnetized by a first coil which receives electromotive force generated by the first thermoelectric couple and fixing the first opening valve moving upwardly; the auxiliary valve comprising:
a second pin moving according to operation of the operation lever and returning to its original position by a third spring;a second opening valve moving according to a movement of the second pin and returning to its original position by a fourth spring;a second cutoff plate mounted for opening and closing the first connection path according to sliding of the second opening valve;a second thermoelectric couple mounted near to flame for generating an electromotive force by the flame; anda second magnet magnetized by a second coil which receives electromotive force generated by the second thermoelectric couple and fixing the second opening valve moving upwardly; a timer operating the main valve to close the inflow path after a lapse of setting time; the burner valve opening the auxiliary flow path so as to supply gas when the main valve moves to open the gas flow path and returning to its original position by a fifth spring; and the ignition device adapted to generate ignition spark when the burner valve is opened to supply gas.
