Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a so-called built-in type cassette stove, which is loaded with a small gas cylinder and press-connected to a gas supply path to a gas burner to be used as a fuel supply source.

Conventional technology Conventionally, in this type of cassette stove, the operation of connecting and disconnecting the cylinder was performed by linearly moving the operating part provided at one end of the lever operating member, whereas the gas supply path Opening/closing and adjusting the opening degree of the gas kettle provided in the middle of the tank are performed by rotating a dial-type operating knob.

Problems that the invention aims to solve: If you want to urgently stop or eliminate abnormal cooking or combustion conditions, simply close the appliance cooker or disconnect the cylinder, and the gas supply to the gas burner will be stopped. Abnormal situations can be resolved. However, in an emergency situation, people often become nervous and easily become confused in properly operating one of the two operating sections with different operating methods. As a result, safety measures may be delayed or may not be taken.

Means for Solving the Problems In order to solve the above-mentioned problems, this invention includes a cylinder setting mechanism that presses and connects the loaded gas cylinder to the gas supply path to the gas burner and releases the connection, and a cylinder setting mechanism that connects the loaded gas cylinder to the gas supply path to the gas burner and releases the connection, and a The operating member of the device provided therein for opening/closing the gas supply passage and adjusting the degree of opening is arranged side by side as a reciprocating operating member that is reciprocated in substantially parallel directions.

The reciprocating operation member is suitably a lever member, a slide member, or the like that is reciprocated in a substantially linear direction, and is usually reciprocated up and down or left and right. Further, it is desirable that each reciprocating operation member is configured such that the cylinder pressing connection operation direction and the instrument pot opening ignition operation direction are the same, and the cylinder connection release direction and the instrument pot closing operation direction are the same, respectively. It is also possible to perform the bomber reset operation in conjunction with the fire extinguishing operation.

Function: The gas cylinder set mechanism connects and disconnects the loaded gas cylinder from the gas supply path, and the gas cylinder opens and closes the gas supply path, and adjusts the degree of opening. On the other hand, stopping the use of the stove with extinguishing the fire requires that at least one of the cylinder setting mechanism's cylinder setting release operation and the appliance cooker's closing operation be performed. Each reciprocating operating member accomplishes the necessary operations of the cylinder setting mechanism and the instrument cock by substantially parallel operations of the same kind and in the same direction.
