Description

[Detailed Description of the Invention] Industrial Field of Use This invention relates to a portable cassette cooker that is loaded with a small gas cylinder and connected to a gas supply path to a gas burner to serve as a gas supply source.

BACKGROUND ART Conventionally, in this type of portable cassette stove, a rotary operation knob has been used to operate the gas supply path opening/closing device.

Problems that the invention aims to solve: Portable cassette stoves are manufactured to be relatively small and lightweight, making them easy to move during use, but opening and closing the appliance using the rotating operation knob generates too much operational reaction force on the stove body. Because it does not allow the stove to open or close, you can open and close the stove without compromising the stability of the stove itself.

However, rotating the knob cannot be said to be the simplest or easiest operation, and if there is a need for emergency fire extinguishing operations in response to abnormalities in cooking or use, it may be difficult to operate, and the stability of the stove may be affected. What is desired is something that can be operated more simply and quickly without sacrificing functionality.

Means for Solving the Problems In this invention, in order to solve the above-mentioned problems, in a portable cassette stove in which a gas cylinder is removably loaded and used as a gas supply source, the gas supply path opening/closing device Kotuku is moved up and down by the vertical operation member. a vertically moving appliance operating mechanism for opening and closing the appliance, and a portion of the outer surface of the stove case from which the vertically operating part of the appliance operating mechanism protrudes, on at least one of the upper and lower sides of the operation area facing the vertically operating part; A finger hook part is provided as a heat conduction part from the stove case.

If the finger hook part itself is a heat conductive member, it may be directly attached to the stove case, or if it is attached via a heat conductive member, it may be a heat conductive member. Alternatively, it may be formed by a part of a heat conduction member attached to the stove case.

The finger-holding portion has a finger-holding surface that protrudes from the outer surface of the stove case and is formed as a protruding piece or a step surface, and the protruding piece in particular protrudes to approximately the same extent as the vertical movement operation part, so that there is no interference with the vertical movement operation part. It is also designed to help prevent undesirable pushing.

The finger grip portion is also provided in an extended or non-extended state at a position opposite to the vertical movement operation portion of the gas cylinder connection/disconnection cylinder setting mechanism provided alongside the instrument control operation mechanism.

The vertical movement operating member of the instrument operating mechanism can be obtained as a lever member or a slide member.

Function The instrument pot operation mechanism opens and closes the instrument pot by simple vertical movement using its vertical movement operation section. The finger grip allows the user to easily and quickly operate the up-and-down operation part in the direction of attracting it, with both hands and fingers clamped together, and also exerts an appropriate operational reaction force on the finger grip to generate an external force for moving the stove. Achieve it without letting it happen.
