前記遮断状態に安定する安全機構が提供されてい
る。(Prior art) In so-called cassette stoves, which mainly use a small-capacity gas cylinder as a fuel source in a removable manner and do not require a hose connection to the fuel source, the gas cylinder is installed very close to the gas burner. It is easily affected by the heat of combustion, and if it becomes overheated, the internal pressure will rise, which is dangerous. In order to solve this problem, conventionally, when the gas supply path to the gas burner is abnormal, the gas supply path is shut off in response to abnormal pressure, and the above-mentioned shut-off state is stabilized by reversing the reversing spring or other operations. A safety mechanism is provided.

れている。(Problems to be solved by the invention) In the above-mentioned conventional system, once the abnormal pressure safety mechanism responds to the abnormal pressure and once cuts off the gas supply path, it stabilizes in the cut-off state, so it is automatically restored and the stove can be used again. It is highly safe as there is no chance of it becoming possible.

えて簡易性を損う。 However, a reset mechanism is sometimes provided to restore the abnormal pressure safety mechanism, but the reset lever is pushed by hand, and a reversing spring or the like is used to set the abnormal pressure safety mechanism to the state where the gas supply path is cut off. In the case of items that can be held strongly, the operating resistance is large, making them difficult to operate and may cause injury to hands and fingers. It is also conceivable to provide a dedicated operating member for the reset mechanism, but this would increase the number of operating parts on the cassette stove and impair its simplicity.

コンロの再使用を阻止することができる。(Function) If the pressure of the gas cylinder increases abnormally due to overheating while the stove is in use, the gas pressure in the gas supply path leading to the gas cylinder also increases in the same way. The normally open valve of the abnormal pressure safety mechanism responds to this pressure increase and closes the gas supply path, and the closed state is maintained by the holding means, so that the gas supply path is shut off and maintained in this state at the same time as the abnormal pressure rise. Therefore, it is possible to prevent abnormally pressurized gas from being supplied to the gas burner thereafter. Furthermore, even if the internal pressure of the gas cylinder returns to normal, the normally open valve in the abnormal pressure safety mechanism will remain closed by the holding means, and it will not be possible to restore the normally open valve by manually releasing it. You can prevent the stove from being reused.

に向上する。According to the present invention, an abnormal pressure safety mechanism is provided in a gas supply passage of a gas burner, which is composed of a normally open valve that closes the gas supply passage in response to an abnormally high supply gas pressure and a holding means for holding the closed state.
A return operation unit is provided which, when operated, exerts a release operating force on the holding means to release the normally open valve from its closed state, thereby returning the normally open valve to its original position. Therefore, if the gas cylinder abnormally rises in pressure due to overheating while the stove is in use, the normally open valve of the abnormal pressure safety mechanism responds to this pressure rise by closing the gas supply line, and this closed state is maintained by the holding means. As a result, the gas supply line is shut off at the same time as the abnormal pressure rise occurs, and this state is maintained, thereby making it possible to prevent gas at abnormally high pressure from being supplied to the gas burner thereafter.
Even if the internal pressure of the gas cylinder returns to normal, the normally open valve will still be held closed by the abnormal pressure safety mechanism, and the stove can be prevented from being used again without manually releasing the normally open valve, further improving safety.

上で有利となる。 Furthermore, the operating member of the instrument handle has an operating part that applies an operating force to the holding means to release the holding of the normally open valve in the closed state, and this operating member is actuated on the holding means by operating the instrument handle operating member. By that,
It is possible to release the normally open valve from being held in the closed state and return the normally open valve, and after the abnormal pressure safety mechanism responds to abnormal pressure and shuts off the gas supply path, the existing operating member can also be used. This operation can restore the gas supply path cutoff state and return the stove to a usable state, and no special operating member is required for the restoration operation for reusing the stove after ensuring the safety of the abnormal pressure. , there is no increase in the number of parts or complication of operation due to the installation of new operation members, which is advantageous in terms of cost and convenience of use.
