is being escaped inside.

In the pot thus constructed, the stopper 11 is removed and water is stored in the tank 15 through the opening 8. The water stored in the tank 15 is heated by a heater 27 to become hot water, which is kept at a temperature of about 95° C. via a thermostat 28. When the amount of steam generated in the tank 15 is small, it gradually escapes to the outside through the through hole 31a, the area around the check valve 32, the small hole 36, the through hole 33, the relief passage 30, and the spout body 38. . When the amount of steam generated is large and the pressure inside the tank 15 rises abnormally, the safety valve 34 rises against the spring 37 due to the pressure, and the steam inside the tank 15 passes through the upper surface of the recess 31 at once. A large amount of the water escapes to the outside through the spout body 38, and an abnormal pressure rise inside the tank 15 is suppressed. Furthermore, if the entire pot is accidentally tipped over, the check valve 32 will move under its own weight toward the packing 35 and close the small hole 36, thus preventing the hot water in the tank 15 from accidentally leaking out. is prevented.

On the other hand, when hot water in the tank 15 is to be taken out, the stopper 11 is unscrewed to open the opening 8, and the hot water in the tank 15 is poured out from the spout body 38 through the opening 8.

Next, the procedure for assembling the tank 15 into the exterior case 1 will be explained. First, the small-diameter opening 18 of the cap 17 is fitted into the opening 8 of the support 6, and the collar 20 is brought into contact with the peripheral edge of the lower surface of the support 6.
Next, a packing 23 is housed in the stepped portion 21, and the flange 22 of the main body 16 is joined to the flange 20 of the cap 17 via the packing 23. and subject 1
A support ring 25 is passed through the outer circumference of the support ring 25, and this support ring 25 is attached to the lower surface of the support body 6 via a screw 26, and by tightening the screw 26, a The joint portion of the collars 20 and 22 is compressed. As a result, the main body 16 and the cap 17 are combined to assemble the tank 15, and the tank 15 is supported and fixed to the support body 6. Thereafter, the outer periphery of the support body 6 is fitted into the upper end opening of the exterior case 1. This completes the assembly of the tank 15 into the exterior case 1.

In this way, the main body 16 and the cap 17 that constitute the tank 15 are assembled as the tank 15 when they are assembled into the outer case 1, and therefore, there are no scratches on the inner peripheral surfaces of the main body 16 and the cap 17 at this time. It is possible to easily determine the presence or absence of a damaged tank 15, thereby preventing the occurrence of an inconvenience such as installing a damaged tank 15.
