[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water stop valve device for a storage container such as a tabletop electric pot when it falls.

[0002]

2. Description of the Related Art A liquid storage container of this type has a passage through which a liquid content is poured out while the container is placed on a table. For this reason, the container communicates with the outside through a passage, and when the container falls, the contents liquid naturally flows out. Such a natural outflow wets the surroundings, and is particularly dangerous when hot water is contained. In order to solve this, conventionally, in the passage, a valve body is provided which moves to the body fall side when the body falls and contacts the valve seat in the passage to close the passage. The valve body has a tapered lower end supported by a small ordinary holding portion which fits the valve body with instability that does not hinder the use, and facilitates the movement when the body falls. As a result, when the body falls, the valve body moves so as to close the passage, so that the above problem is solved.

[0003]

However, in the above-mentioned conventional valve body, it sometimes happens that the flow of the content liquid is seen without closing the passage at the initial stage of the fall of the body. This is because even if the vessel body falls over and the inner solution tries to flow out and pushes the valve body to contact the valve seat in the passage, the valve body is slightly moved by the inner solution trying to flow out. This is probably due to the poor sealing caused by the contact between the body and the valve seat.

Therefore, the present invention provides a water stop valve device for a fall of a liquid storage container, which can solve the above problems by improving the sealing structure between the valve body and the valve seat in the passage. The task is to do so.

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention moves to the passage leading to the outside of the body by moving by its own weight to the fall side of the body when the body falls. In a water stop valve device for a fall of a storage container provided with a valve body that abuts a valve seat and closes a passage, in a valve body and a valve seat, an annular main seal portion that abuts each other, and a circumference of the main seal portion. Then, at least they are close to each other to form an annular sub-seal portion that suppresses the flow of the inner solution to the main seal portion.

[0006]

According to the above configuration of the present invention, when the body falls, the valve body moves to the fall side of the body and abuts or comes close to the valve seat in the passage. By having a main seal portion that abuts in an annular shape on the inner side and a sub seal portion that abuts on the outer side of the main seal portion at least in an annular shape, the sub seal portion may be such that the valve body and the valve seat are at least in close proximity. Despite the function of being slightly moved by the inner solution that tries to flow out from the valve body and the valve seat in the main seal part, make it easy to contact and let it flow out the passage when the body falls. The flow of the inner solution to the main seal part can be suppressed by the proximity of the valve body and the valve seat, and even if there is an inner solution passing through the sub seal part to the main seal side, There is no momentum and the amount is small Runode, the valve body and the valve seat can be reliably prevented from flowing any more outside reliably caught by the main seal portion of the contact tends to state, it is possible to improve the waterproofing function of the passage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention shown in FIGS. 1 to 4 show the case of a boiling type electric pot in which an inner container 3 having a heater 2 is housed in an outer case 1 as a hot water storage container.

The inner container 3 and the outer case 1 are connected at the upper end by a shoulder member 4 and at the lower end by a connecting fitting (not shown) and a bottom member 5 to form a body 6 of an electric pot. There is.

At the front part of the shoulder member 4, the outer circumference thereof is the shoulder member 4
An inverted U-shaped tube 24 having a discharge port 8 for discharging the content liquid to the outside, which is integrally formed with a bulging portion 7 formed of a convex curved surface in contact with the outer peripheral surface of A spout 51 including a base of the inverted U-shaped pipe 24 and a valve chamber 41 for stopping water in the event of a fall.
Is built in. At the rear of the shoulder member 4, the shaft 10 of the bearing 10
A lid 11 is pivotally attached so as to be openable and closable by a. An inner lid 12 is attached to the lower surface of the lid 11 so as to be in close contact with and close to the mouth portion 3a of the inner container 3.

Inside the lid body 11, there are provided a bellows pump 14 which is pressed by an upper surface pressing plate 13 of the lid body 11 and a valve 15 arranged in the center thereof. The valve 15 has a valve packing 15b at the lower end of a valve rod portion 15a that penetrates the bellows pump lower plate 16.
The valve packing 15 is installed around the valve stem 15a.
A valve passage 15c that is opened and closed at b is formed.

The air pressurized by the pressing operation of the bellows pump 14 is sent from the valve passage 15c through the passage member 17 into the inner container 3 through the opening 12a of the inner lid 12 as shown by the arrow in FIG. It is designed to pressurize the liquid. Passage member
The space 17 is arranged in the space between the inner lid 12 and the bellows pump lower plate 16. Further, the passage member 17 is a bellows pump lower plate 16
The inner lid 12 is fixed to the spacer 27 integrally formed with the inner lid 12 with a screw so as to be held between the bellows pump lower plate 16 and the inner lid 12, and the passage member 17 and the bellows pump lower plate 16 and the inner lid 12 are Seal packing 18 interposed between each
The air passage is sealed at a and 18b.

When the bellows pump 14 is pressed, the valve passage 15c closed by the valve packing 15b is opened by the downward movement of the valve rod portion 15a of the valve 15, and the valve packing 15c is opened.
At 15b, the valve port 19 of the vapor vent passage 20 provided in the passage member 17 is closed, and the pressurized air is reliably fed into the inner container 3 without leaking to the outside. When the bellows pump 14 is not pressed, steam generated when the heater 2 keeps warm or boils is released to the outside of the lid through the steam vent passage 20. In other words, when the content liquid is not poured, the vapor flows from the opening 12a of the inner lid 12 to the valve port 19 of the passage member 17 and the vapor vent passage.
20 and the passage 11b at the rear of the bellows pump 14 in the lid 11.
Through the opening 11a on the outer surface of the lid 11 through the
The inside of the inner container 3 is configured so as not to be abnormally pressurized.

A lead-out path 22 for guiding the pressurized content liquid to the upper outside of the inner container 3 is provided with its base end connected to the bottom of the inner container 3. The outlet path 22 has the upper end at the valve chamber.
It is connected to the lower end of 41 through the elbow 21, and one end is the inner container 3
The content liquid in the inner container 3 always flows in and maintains the same level by communicating with the inside and opening the other end to the outside by the discharge port 8, and the liquid formed by the transparent tube 23 in the middle thereof. It serves as a quantity display.

The pouring portion 51 is connected to the end of the transparent tube 23,
The liquid to be poured out is discharged from the outlet 22 to an elbow connected to its upper end.
It passes through the inside 21 and is discharged from the downward discharge port 8 through the inverted U-shaped tube 24, and the discharged liquid is discharged to the outside through the liquid injection guide 25 arranged so as to be received from below. This injection guide
25 is integrally formed with a bottom lid 52 that closes the opening 7a of the bulging portion 7. The bottom lid 52 is a horizontal plate fitted between the bulging portion 7 and the shoulder member 4 and the outer case 1 of the body 6 (FIGS. 1, 5, and 6).

However, the bottom lid 52 has a cover portion 52a which is slightly bulged downward so as to cover the portion of the spout portion 51 which is projected slightly downward from the bulging portion 7. The bottom lid 52 has a shoulder member 4 of the body 6 and an end portion 52b having a shape correlating with the substantially flat front surface of the outer case 1 at the rear end and is abutted on the shoulder member 4 and the outer case 1 without any gap. The pair of left and right engaging claws 52c formed on the end portion 52 are engaged with the upper edge 1a of the outer case 1, and the tip 52b is engaged with the engaging claw 7b at the tip of the bulging portion 7. Therefore, it is installed stably.

Inside the valve chamber 41, a partially expanded chamber is formed in the middle of the outlet channel for the content liquid. As a result, even if the valve body 9 that shuts off water in the event of a fall is built in, a sufficient outlet flow path can be formed around it. In the lower part of the valve chamber 41, a normal holding portion located in a central portion not obstructing the outlet flow passage and integrated with the valve chamber 41 by a rectifying rib 42.
The normal holding portion 43 is adapted to receive and hold the valve body 9 in the normal position of FIG. 1 which does not interfere with the outlet flow passage. Normally, the holding portion 43 has a shallow and small mortar shape, and by receiving and holding the tapered lower end portion 9a of the valve body 9, during normal pouring of the content liquid, the valve body 9 is stabilized in that holding state. However, when the body 6 falls, the valve body 9 is easily moved from the holding portion 43 to the fall side of the body 6.

The base of the inverted U-shaped pipe 24 is located above the valve chamber 41.
An annular valve seat 44 that projects slightly downward is formed inside 41, and an annular ridge 45 having a larger diameter than the valve seat 44 is formed on the outer periphery of the upper surface of the valve body 9. A straightening guide rib 46 is formed on the inner periphery of the upper half of the valve chamber 41 to guide the movement of the valve body 9 toward the valve seat 44 (FIGS. 2 and 3).

As a result, the valve body 9 tends to move to the falling side when the body 6 falls, but the normal holding portion 43
Is smoothly guided to the valve seat 44 side by the guide of the receiving surface and the guide of the rectifying guide rib 46, the upper surface 47 on the center side of the valve body 9 contacts the valve seat 44, and the convex stripes of the valve body 9 45 abuts the auxiliary valve seat 48 outside the valve seat 44. Therefore, since the pouring flow path is closed at the double annular contact portion as shown in FIG. 3, it is possible to surely stop water in the event of a fall. This 2
It is difficult for both the heavy annular contact portions to come into close contact with each other in terms of processing and assembly accuracy. However, it was confirmed that even if a gap was created in one of the contact portions, it was very small, and the double seal structure exhibited a significantly higher water shut-off function than the single seal structure.

By the way, the gap can be formed as an annular seal portion by the convex line 45 of the valve body 9 which is the outer seal portion and the auxiliary valve seat 48, and the upper surface 47 of the valve body 9 which is the inner seal portion and the toilet seat 44. It was also confirmed by an experiment that the annular seal portion formed by means that the sealing function is good when both are in contact with each other.

Therefore, in the inner and outer double annular seal portions, at least the inner seal portions abut each other to form a main seal portion A that firmly blocks the outflow of the inner solution, and the outer seal portion has a gap. It is preferable that the sub-seal portion B is formed, which may be present, that is, at least close to each other so that the inflow of the inner solution into the main seal portion A can be suppressed.

The present invention is characterized by such a structure. When the body 6 falls, the valve body 6 moves to the fall side of the body 6 and the valve seat 44 or the auxiliary valve seat in the outlet passage 22. A main seal portion A that abuts or comes close to 48, but the valve body 9 and the valve seat abut on each other in a ring shape, and the main seal portion A.
And a sub-seal portion B which is annularly adjacent to each other on the outer side of the sub-seal portion B, and the sub-seal portion B has only to have the valve body 9 and the auxiliary valve seat 48 at least close to each other. The inner solution that tends to come into contact with the valve seat 44 despite being slightly moved by the inner solution that tries to flow out, and the inner solution that tries to flow out of the outlet passage 22 when the body 6 falls Due to the proximity of the valve body 9 and the auxiliary valve seat 48 to the main seal portion A, the momentum and flow rate can be suppressed, and even if there is an internal solution passing through the sub seal portion B to the main seal A side, Since there is no momentum or a slight amount in this, the valve body 9 and the valve seat 44 are
With the main seal portion A in a state where they easily come into contact with each other, the main seal portion A can be surely received, and further flow to the outside can be surely prevented, and the water stop function of the passage can be improved.

When the valve body 9 abuts on the valve seat side in an inclined state as shown in FIG. 2, only a part of the outer side of each of the double annular abutting portions comes into contact at the initial stage of abutting. Although not in contact with each other, since the pouring flow path is extremely narrow and has a complicated labyrinth shape, it is possible to greatly limit the natural outflow of the content liquid and sufficiently suppress the outflow. While exhibiting the deterrent function, the valve body 9 appropriately contacts the valve seat 44 and the auxiliary stool 48 or relatively close to the valve seat 9 due to the dynamic pressure of the inner solution that is about to flow out, and pushes the valve body 9 to an appropriate water stop state. Therefore, the water blocking function in the outlet path 22 does not deteriorate to such an extent that it becomes a problem.

Further, the valve element 9 has a tapered shape at the lower end,
A recess 9b is provided at the center of the lower end so that the center of gravity G is located above the valve body 9 as shown in FIG. As a result, the center of gravity G of the valve body 9 has a large amount of deflection X from the center line S associated with the inclination of the body 6 due to the fall, so that the valve body 9 is removed from the normal holding portion 43 to the fall side of the body 6. Make it easier. Therefore, the valve body 9 easily moves to the valve seat side when the body 6 falls, and the water stop function at the time of fall can be further improved.

The center of gravity G of the valve body 9 is located above the valve body 9, but is normally located on the center line S of the valve body 9, so that the body 6 is in an upright state. , The center line S does not swing at all. Therefore, since there is no function of moving the valve body 9 from the normal holding portion 43, the holding of the valve body 9 in the normal holding portion 43 is not affected and the normal pouring of the content liquid is not disturbed.

A check valve 26 is provided at a portion of the passage member 17 facing the opening 12a of the inner lid 12 to prevent the content liquid from flowing out through the vapor vent passage 20 when the body 6 falls. There is.

In order to prevent the liquid content from being poured out even when the upper pressing plate 13 is accidentally pressed, a safety knob 28 that is locked to the upper pressing plate 13 to prevent its downward movement is provided on the lid 11. Is provided at the rear part of the upper surface of the switch so as to be switchable between a locking position and a locking release position. Further, the lid body 11 is always biased in the opening direction by a spring 29 provided in the pivot portion, and a closing means 30 for locking the lid body 11 in a closed state is provided at the front portion of the lid body 11,
A lock release button 31 is provided on the upper surface thereof. Further, in order to prevent the lid 11 from being opened accidentally, a safety knob 32 for disabling the lock release button 31 is provided.

The bulging portion 7 is, as shown in FIG.
The upper surface is formed so as to project upward so as to be higher than the upper edge 4a of the other portion of the shoulder member 4, and an operation portion 33 for instructing heating control by the heater 2 is provided on the upper surface. The operating portion 33 is wide because the bulging portion 7 is wide.

As described above, since the operating portion 33 is provided on the upper surface of the bulging portion 7 in an upward direction, the operation is easier than in the case where it is provided on the front surface, and the display of the operating portion 33 is easy to see. Further, since there is no fear that the body 6 moves or falls during the operation, it is easy to use. Also, in this way the operation part
Even if 33 is provided on the upper surface of the bulging portion 7, since the bulging portion 7 is formed so as to project above the upper end edge 4a of the shoulder member 4 which is the upper end edge of the mouth portion of the body 6, When the lid 11 is opened and the content liquid is poured into the inner container 3 or the residual liquid is taken out, there is no possibility that the liquid will flow to the upper surface of the bulging portion 7, and therefore the liquid will enter the operating portion 33. There is no such thing as causing harm.

The operating portion 33 is, as shown in FIGS. 2 and 4,
An electric board 62 is housed in a recess 61 formed on the upper surface of the bulging portion 7, and a cover sheet 63 is provided so that the electric board 62 can be pressed from above. As shown in FIGS. 2 and 4, the electrical equipment substrate 62 is positioned by fitting the notch 62a at the center of the tip to the protrusion 61a at the center of the tip inside the recess 61.
It is screwed to the protrusion 61a by 66.

On the back surface of the operating portion 33, as shown in FIG. 7, inner and outer peripheral walls for joining the inner container 3 of the shoulder member 4 and the outer case 1 to each other.
A pair of left and right holding walls 54 extending downward is also formed along the inner peripheral wall 4c of 4c and 4a (FIGS. 1 and 7). The spout 51 is sandwiched between these holding walls 54 to form the spout 5
The spouts 51 are stably held by engaging the projections 55 formed on both sides of the No. 1 with the locking holes 56 of the holding wall 54. The outlet passage 22 is stabilized by two-point support of the holding portion of the spout 51 and the connecting portion of the base portion to the inner container 3.

Reference numeral 34 is a handle pivotally supported at the center of the shoulder member 4 in the front-rear direction, and reference numeral 35 is a magnet outlet for supplying electric power to the heater 2 provided at the rear portion of the bottom member 5.

In the above embodiment, the case of the electric pot is shown, but the present invention is not limited to this, and the present invention can be applied to all portable liquid storage containers. Further, it can be applied to all passages using the water shutoff valve device at the time of fall.
