It has a built-in water level gauge (not shown) that displays the amount of hot water inside.

Next, a procedure for assembling the stopper ring 63 and the operating lever 66, which selectively restrict vertical sliding of the pusher 44, will be explained.

First, as shown in FIG. 4, from above the lid body 28, cover 5Q,
The pusher body 44 on which the decorative plate 61 is set is engaged. At this time, the front protrusion piece 481L of the pusher body 44 is positioned in the notch groove 301L narrowed at the front end of the lid body 28, and the protrusion pieces 48&, 4B are inserted into the notch grooves 30a, 300r, 306.
After loosely fitting and passing the protruding pieces 48° 48& into the inner flange 32 of the lid body 28.

Rotate in direction A shown in FIG.

47a is loosely fitted. Next, the operation knob 67 of the operation lever 66 is engaged with the opening window 3.3 VC, and the guide cylinder 3 of the lid body 28 is
6 and the outer wall. after that.

Stopper ring 53rd notch hole 63a, 530°aS
d through the protruding pieces 48&, 48 of the pusher body 44.

Furthermore, the notch holes 5sb, s3c, and 53e are aligned with the hook pieces 31 of the lid body 28. That is, as shown in FIG. 5, the stopper ring 53 is rotated in the direction B so that the retaining piece 54 and the locking piece 6o of the operating lever 66 are not in contact with each other, and the stopper ring 63 is attached to the hook piece 31 of the lid body 28. , and further rotate it in the input direction to release the stopper ring 6.
3 is guided by the guide piece 59 of the operating lever 56, and the retaining piece 64 is used to get over the inclined surface 6ob.

Then, the engagement with the locking piece 6o is completed by engaging the recess 60&.

That is, the operating lever 66 is rotated by the operating knob 67 in the direction C shown in FIG.
is operated by climbing over the click rib 306 of the lid body 28. Therefore, the sliding restriction of the pusher body 44 will not be released due to vibration or the like, causing the pusher body 44 to naturally rotate to its original position.

However, the stopper ring 63 has a braking effect due to the hook piece 31 and the protrusion 34 provided on the back surface of the inner flange 32.

The operation of the air pot configured as described above will be described below.

First, fill the container 1 with water, press the switch lever 66 and set the thermo switch 8 to ON, and the main heater 2
energization is started. Although the water in the container 1 is heated and its temperature rises, the temperature in the compartment A formed by the shielding plate 26 rises later than the water temperature. The temperature inside the mounting tube 7 where the thermo switch 8 is installed rises later than the inside of the compartment A. Therefore, as the water heats up and the water temperature reaches the boiling point, a large amount of steam is suddenly generated, and the steam is vented. It is ejected from the vent hole 241L of the nozzle 24 into the mounting cylinder 7, rapidly raising the temperature of the heat-sensitive surface 8a of the thermoswitch 8, and turning it off. The power supply to the main heater 2 is cut off by the OFF operation of the thermoswitch 8, but after that, the power supply to the auxiliary heater 3 is controlled by the heat retention temperature regulator 6 to keep it warm. A parallel circuit is formed with a four-piece thermoswitch 8 for boiling water temperature, and when the thermoswitch 8 is not set to ON, water boiling is controlled at a water temperature that does not reach boiling. In addition, a safety temperature controller 6
are connected in series to both parallel circuits, and operate even if a short circuit occurs in either regulator to ensure safety.

When boiling or boiling is completed, the pusher 44 is pressed to pour out the hot water, but when the pusher 44 is finished operating, the stopper ring 63 is pressed via the operating lever 66 with the knob 67. (7) The positions of the notch holes 53al 53b, 530 and the stopper 47.
This controls the vertical sliding of the

According to the embodiment of the present invention, the operating lever 56 is curved concentrically between the outer wall of the lid 28 and the guide tube 30, and the operating knob 67 protrudes from the opening window 33. The engaging piece 64 of the stopper ring 63, which is loosely fitted into the hook piece 31 provided on the inner flange 32 at the lower end of the lever, is rotated in the horizontal direction.
The simple structure of engaging the pusher body 44 can reliably restrict vertical sliding of the pusher body 44.

In one embodiment of the present invention, the operation knob 67 of the operation lever 66 is made to protrude from the opening window 33 on the front side wall of the lid body 28, but the operation knob 67 of the operation lever 66 is made to protrude from the opening window 33 on the front side wall of the lid body 28. It goes without saying that the same effect can be obtained by providing one window and providing an operating knob at the upper end of the operating lever so that the operating knob projects beyond the open window. Furthermore, the operating knob does not have to be configured to protrude from the opening window.

Effects of the Invention As described above, according to the present invention, there are provided a pot body housing a container for storing a liquid to be poured, a bellows communicating airtightly with the container, and a lid body housing the bell. a guide tube extending inwardly at the top of the guide tube and open at the top; a pusher body provided vertically slidably in the guide tube; and a pusher body rotatably provided in the guide tube and the pusher a stopper ring for regulating vertical sliding; the lower end of the operating lever is engaged with a retaining piece extending from one side of the stopper ring; The stopper ring and the operating lever can be easily assembled because the stopper ring and the operating lever are provided so that they can be freely rotated while being guided between the stopper ring and the operating knob. In addition, it is possible to reliably restrict the vertical sliding of the rotation operation pusher of the operation lever by the operation knob provided on the operation lever.
