In order to display the water level inside the pot, a water level pipe that also serves as a pumping pipe is provided, and the water level pipe is exposed to the water level display window on the pot body. The structure in which a water level plate is provided behind has been conventionally used in various pots.

The lower end of the water level pipe is connected to the inner container by a flexible lower connecting tube, and the upper end thereof is also connected to the safety valve set by an upper connecting tube. Further, the water level pipe and the water level plate are independent of each other, and one of them is not structured to regulate the movement of the other.

[Problems to be solved by the device]

As described above, according to the structure in which the upper and lower ends of the water level pipe are connected to the inner container and the safety valve by the connecting tubes, when the inner container is assembled in a state where the position of the inner container is deviated from the trunk in the assembly process, the lower connection described above is connected. Since the tube is twisted, the water level tube is tilted with respect to the water level display window of the body, and the center of the both does not match.

The water level pipe must be installed vertically in terms of its function, and in terms of design, it is desirable that the center of the water level pipe and the center of the water level display window coincide.

Therefore, an object of the present invention is to provide a structure in which the water level tube and the center of the water level display window are aligned even if the inner container is assembled in a state of being displaced from the body.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention is to connect a lower end and an upper end of a water level pipe which also serves as a pumping pipe to an inner container and a safety valve set by connecting tubes, respectively, and connect the safety valve set to a shoulder body or a member integrated with the shoulder body. Fixed in the water level tube mounting structure of the pot in which the water level plate is arranged behind the water level tube, the body having the water level display window is circumferentially positioned and fitted to the shoulder body or a member integrated therewith, The upper end of the water level plate is fixed to the shoulder body or a member integrated with the shoulder body, and the lower end of the water level tube is inserted and held in a positioning hole formed in the lower end of the water level plate.

[Action]

The safety valve set and the water level plate are respectively fixed to the shoulder body or a member integrated with the shoulder body, and the upper end of the water level tube is connected to the safety valve set via a connection tube. Further, the lower end of the water level pipe is inserted into a positioning hole at the lower end of the water level plate, and is held by the inner peripheral edge thereof. Therefore, the water level tube is positioned and held vertically with respect to the shoulder body or a member integrated with the shoulder body.

Since the body having the water level display window is circumferentially positioned with respect to the shoulder body, the center of the water level tube and the center of the water level display window coincide with each other.

Even if the inner container is assembled with respect to the barrel at a position displaced from the prescribed position, the displacement is absorbed by the twist of the lower connecting tube of the water level pipe.
