This lid 1 covers the lower side of the outer lid 2 with a lower plate 3, and
A steam case 4 and an inner lid 5 are attached to a lower plate 3, which is rotatably attached to a shoulder body 7 of a main body 6 by a hinge pin 8 so that an inner container 9 can be opened and closed. In addition,
In the lid 1, the side opposite to the hinge pin 8, that is, the side of the spout 10 of the main body 6 is hereinafter referred to as the front side or the front side, and the side of the hinge pin 8 is referred to as the rear side or the rear side.

The steam case 4 has an annular side wall portion 11, a bottom portion 12 that is convexly curved downward, a tubular vertical portion 13 having a rectangular cross section that protrudes downward from the bottom portion 12, and a flange on the outer peripheral surface of the side wall portion 11. And a mounting portion 14 projecting in a shape. A steam hole 15 is provided on the rear side of the side wall portion 11 of the steam case 4, and a vent hole 16 is provided on the front side surface of the vertical portion 13, and as shown in FIG. A pair of guide plates 17, 17 are provided on the left and right sides of and extend forward.

A seal packing 18 which is pressed against the upper end of the inner container 9 housed in the main body 6 is attached to the outer periphery of the inner lid 5, and a plurality of vent holes are formed in the bottom of the protruding portion 19 projecting downward in the center and the outer periphery thereof. 20a and 20b are provided. Between the projecting portion 19 of the inner lid 5 and the vent hole 16 of the steam case 4, the spherical valve body 12 for preventing water leakage at the time of falling is accommodated by the guide plates 17 and 17 while restraining the horizontal movement in the left-right direction. Has been done.

A seal packing 22 is interposed between the steam case 4 and the inner lid 5, and they are attached to the lower plate 3 by attachment screws 23. Then, the ventilation port 20 of the inner lid 5
From a and 20b, the vent hole 1 of the vertical part 13 of the steam case 4
6, through the steam hole 15 of the side wall portion 11, the gap between the lower plate 3 and the inner lid 5 and the steam pipe 24 provided between the outer lid 2 and the lower plate 3, to the steam port 25 provided in the outer lid 2. A vapor passage A to reach is formed.

A bellows pump device 30 is housed between the outer lid 2 and the lower plate 3 of the lid body 1.

The lower end of the bellows 31 of the pump device 30 is welded to the lower plate 3 to be covered, and the upper end is welded to the cover 32 to be covered, so that the inside is a closed space. The first spring 33 is housed in a compressed state between the cover 32 and the lower plate 3. An intake port 34 is formed in the cover 32, and an intake valve 35 is attached to the cover intake port 34. Further, a tubular guide member 36 is provided on the inner surface of the center of the cover 32, and a vent hole 37 is formed in the guide member 36.
A tubular rod 38 having is fitted slidably. The upper end of the rod 38 is locked to the lower end of the guide member 36, and the lower end penetrates the lower plate 3 and projects into the steam case 4. The rod 38 is biased downward by the second spring 39 housed in the guide member 36. A rod packing 40 integrally formed with a check valve 40a is attached to the lower end of the rod 38.

The bellows 31 can be pressed from the outside by a push button 42 slidably fitted in a guide cylinder 41 provided on the top of the outer lid 2.

In the electric pot having the above structure, when the push button 42 is not pushed, the bellows 31 is fully extended by the first spring 33 and pushes up the push button 42 as shown in FIG. The rod 38 is biased downward by the second spring 39. Therefore, the upper end of the rod 38 has the guide member 3
6, the rod packing 40 is attached to the lower end of the steam case 4
Separated from the edge of the vertical 13 of the above, the steam hole 15 and the vent hole 16 are open. So in this state,
The steam generated when boiling comes from the vent holes 20a and 20b of the inner lid 5.
Through the vent hole 16, the steam hole 15 and the steam passage A, and flows out from the steam port 25.

When the lid 1 of this electric pot is opened and closed rapidly, the first
As shown by the chain double-dashed line in the figure, the valve body 21 may float, but since the vent hole 16 is provided in the front side wall of the vertical portion 13, the vent hole 16 is not closed. Therefore, no matter how rapidly the lid 1 is closed, the steam passage A remains open, so that the hot water in the inner container 9 is not spontaneously discharged from the inlet 10.

Then, assuming that the electric pot body is, as shown in FIG.
If the inlet 10 is turned down, the valve body 21 rolls forward and separates from the vent hole 16, so that the steam passage A remains open. However, in this case, the vapor port 2 of the lid 1
As a result of 5 being located above and steam path A facing upward, hot water in inner container 9 does not leak even if steam path A is open.

Further, as shown in FIG. 4, the electric pot body has a spout 1
When 0 is turned upside down, the valve body 21 rolls backward and closes and seals the vent hole 16, so that the steam passage A is closed. Therefore, in this case, the vapor port 2 of the lid 1
Even if 5 is positioned downward and the steam passage A faces downward, the hot water in the inner container 9 does not flow into the steam passage A and does not leak to the outside.

In this electric pot, when the push button 42 is pushed down, the bellows 31 starts to contract and the rod 38 descends, and the rod packing 40 presses against the bottom portion 12 of the steam case 4, so that the steam passage A is closed.

Therefore, when the push button 42 is pumped within the range in which the bellows 31 does not fully extend, that is, the lower end of the guide member 36 does not engage with the upper end of the rod 38, the air in the bellows 31 sequentially enters the inner container 9. A large amount of hot water fed into the inner container 9 can be continuously discharged without interruption.

(Effect of the Invention) As is clear from the above description, according to the present invention, the vent hole is not closed even when the valve body is lifted when the lid is closed, so that the hot water or water inside is naturally discharged from the spout. There is nothing to do. Further, even if the main body falls down and the steam passage faces downward, the valve body blocks the vent hole, so that hot water or water inside does not leak from the steam passage, which is safe.
