A vertically long through hole is bored on the side, and a frame 20 covering the vertically long hole is fixed to the front surface of the vertically long through hole.

This frame body 20 has a vertically long transparent window 21 through which the vertically long liquid level display tube 12 can be seen through the vertically long transparent hole of the exterior case 1.
A kettle is provided inside the lower end, and each lamp 22 for heat retention is provided.
23, and a transparent glass or resin plate is fitted into the transparent window 21.

The drainage member 5 attached to the upper end of the outer case has an open center, and the annular flange 10 of the inner container 2 is fixed to the circumferential surface of the drain member 5.
An annular rib 24 is provided on which the top cover can be attached and detached, a beak 26 is provided on the front surface on which the discharge pipe 25 of the inner stopper is placed, and a hinge device 27 is provided on the outer wall of the rear end for attaching the top cover so that the top cover can be opened and closed. There is.

28 is a locking device 29 for the upper lid 8 provided on both sides of the beak part
This is a locking pawl that locks the locking pawl 30 of.

The inner cap 6, which is removably attached to the opening of the inner container 2, is fixed to the inner cap body 31 and the outer periphery 1' of the inner cap body, and has an inner cap 32 that closes the opening of the inner container, and its lower end hangs down inside the inner container. A water lift pipe 34 whose upper end communicates with the liquid communication part 33 of the inner stopper body, and a water lift pipe whose tip protrudes from the beak 26 of the drainage member to the front of the outer case 1 and whose rear end communicates with the liquid communication part 33 of the inner stopper main body. 34 and a discharge pipe 25 communicating with the discharge pipe 34.

The upper cover 8, which is attached to the upper end of the draining member 5 so as to be freely openable and closable, has a bellows 7 which is opened at the center of the upper and lower ends, a lower plate 36 to which the center of the lower end of the bellows is attached via a packing 35, and is fixed to the rear end of the draining member. A hinge device 27 for opening and closing the top lid, a locking device 29 for the top lid including a locking pawl 30 that locks into a locking pawl on a draining member, a top plate 37, and a bushing valve 38 locked in the opening at the center of the upper end of the bellows. A spring 39 that pushes up the bushing valve from within the bellows, and a pusher body that is freely movable up and down within the center opening of the upper plate and contacts the upper end of the bushing valve to supply air in the bellows to the inner container through the inner stopper. 40, and a stopper device 41 for stopping the vertical movement of this pushing body.

A heat source 3 that heats the liquid in the inner container is fixed to the outer periphery of the lower end of the inner container, and power supply is controlled by a thermostat C1 that senses the temperature of the liquid in the inner container and a temperature regulator C of a thermal reed switch C2. has been done.

This heat source 3 lights up the water boiling lamp 22 when boiling water,
The O plug 19, which lights up the heat retention lamp 23 during heat retention, is connected via lead wires to the water boiler, heat retention lamps 22, 23, temperature fuse 42, thermal reed switch C2, thermostat C1, and heat source 3. .

This invention can be used not only for pots that boil water and keep it warm, but also for other air pots, handy pots, and portable pots.

As described above, in the present invention, through holes are bored at the upper and lower ends of the inner container, an annular packing is stretched from the inside and outside of the through holes, and a joint is protruded into the inner container to store the contents. The structure is simple, as it is screwed in with a nut from inside the container, and a unit member is fitted to a joint on the outside of the inner container, and a liquid level indicator tube is fitted to this unit member. Installation is very easy.

Furthermore, when disassembling the liquid volume display tube, the unit member, and the joint can be disassembled simply by loosening the nut inside the inner container.

Furthermore, the through hole of the inner container is lined with packing from the inside and outside and tightened with nuts, so it is completely sealed and there is no risk of liquid leakage.
