Means for Solving the Problems In order to solve the above problems,
The present invention is a mounting structure of a pan bottom temperature sensor provided so as to be inserted through an inner diameter portion of an annular burner mounted on a stove, and a holder attached to a rod portion of the pan bottom temperature sensor extending below the inner diameter portion of the burner. At the lower end of the holder, a seat plate portion to be seated on the upper surface of a holder for a holder formed on the support frame is provided on a support frame provided in the body of the stove. A protruding piece is formed, and a spring member is provided which is detachable from the protruding piece and presses the seat plate against the seat.

According to this, the hand can be inserted from the outside of the burner into the container of the stove, and the spring member can be detached from the protruding portion, whereby the pan bottom temperature sensor can be removed. Therefore, even if the inner diameter of the burner is small, the pan bottom temperature sensor can be easily attached and detached without removing the burner, and the workability when assembling the docking type gas appliance to the system kitchen is improved.

As a preferred example of attachment by a spring member, the protruding portions are formed in a pair, and the spring members are constituted by bar-shaped springs which are elongated in the left-right direction, with the opposing directions of the two protruding portions being the left-right direction. A substantially L-shaped engagement groove having a horizontal groove portion in which a bar spring can be inserted and removed in the front-rear direction and a vertical groove portion extending upward from the horizontal groove portion is formed in each of the projecting pieces. A pair of bent legs connected to the pair of engagement portions with the engagement grooves of the one-piece portion, and a lever portion capable of rotating the rod-shaped spring around an axis in the left-right direction are formed. When the bar-shaped spring is turned downward with both legs by operating the lever portion in a state where the joint portion is engaged with the vertical groove portion of the engaging groove of the both projecting portion portions, both leg portions are turned to the seat plate portion. Contact from above,
In some cases, the seat plate is pressed against the seat. According to this, since the engaging portion of the bar-shaped spring presses against the upper end of the vertical groove portion of the engaging groove by the contact reaction force from the seat plate portion acting on the leg portion, the engaging portion is in the horizontal groove portion of the engaging groove. To prevent the bar spring from accidentally detaching from the protruding piece. On the other hand, if the bar-shaped spring is rotated so that the leg portions are directed in the front-rear direction, the engaging portion is shifted to the horizontal groove portion, and the bar-shaped spring can be easily separated from the projecting piece. Here, although a considerable torque is required for the rotation of the rod-shaped spring, the lever is provided, so that the rod-shaped spring can be rotated with a light force by leverage, thereby improving workability.

In order to stabilize the rod-shaped spring in a state where the seat plate is pressed, it is necessary to stop the rod-shaped spring at a position beyond the dead point where the leg is rotated slightly more than the dead point where the leg is directed downward. In this case, it is conceivable to form a stopper portion on the seat plate portion where the leg portion is engaged at a position beyond the dead center. However, in this case, it is necessary to perform processing for the stopper portion on the seat plate portion, and cost is reduced. Get higher. On the other hand, if the two leg portions are bent in different directions so that the two leg portions have an angle difference when viewed from the left and right directions, the rod-shaped spring is moved from the dead center position where one leg portion is directed right below. Is further rotated, the other leg abuts against the seat plate, and the bar spring is stopped at the position beyond the dead center. In this case, there is no need to perform special processing on the seat plate portion, and the cost can be reduced.

Further, the projecting pieces are formed as a pair, and the spring member extends from one end in the front-rear direction to the other end in the front-rear direction with the opposing direction of the two projecting parts being the front-back direction. An engagement hole which is formed of a substantially V-shaped folded spring having a pair of left and right side sides, and which allows the folded portion of the folded spring to be inserted into one of the projecting portions in the front-rear direction, and the other projecting portion in the front-rear direction. An engaging portion engageable from outside in the left-right direction and from above is formed on both side portions of the return spring. The curved portion may be formed so that the curved portion is abutted against the seat plate from above, and the seat plate is pressed against the seat.
