Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention prevents a content liquid from flowing out when a container falls, in a pouring passage for pouring out the content liquid and a vapor discharge passage for discharging vapor emitted from the content liquid to the outside. The present invention relates to an electric hot water storage container provided with a water shutoff valve for a fall.

[0002]

2. Description of the Related Art In an electric pot or the like, the content liquid is discharged to the outside and the vapor generated by heating the content liquid is discharged to the outside through a lid body to the outside of a pouring passage for using the liquid. A steam vent passage is provided to prevent abnormal pressurization.

Further, the electric pot sometimes falls due to careless catching or the like during use or stationary, and when the body falls, the liquid contents flow out to the outside through the pouring passage and the vapor vent passage. However, it is dangerous because it wets the surroundings and is hot water.

Therefore, in order to prevent inadvertent outflow of the content liquid due to such a fall of the container, the pouring passage and the steam vent passage are closed by closing these passages when the container falls. It is also practiced to provide a water shutoff valve to prevent water fall.

JP-A-59-115015, JP-A-58-67219 and JP-A-58-672.
Japanese Patent Laid-Open No. 00 discloses an electric hot water storage container having such a water stop structure at the time of tipping.

[0006]

However, these devices have a lid for opening and closing the upper end of the container, and an inner lid provided separately from the lid and attached to and detached from the mouth of the inner container. Both the pouring passage for the content liquid and the vapor discharging passage pass through the inner lid portion. For this reason, if the inner lid is forgotten to be attached, the inner solution cannot be poured out, and if the vessel falls, the mouth of the inner container remains open, so The internal solution will flow out regardless of the position or structure where the is installed. Further, even if the lower surface of the inner lid is formed of a metal member as described in the publication, if the inner lid is forgotten to be attached, the lower surface of the lid body is exposed to high temperature steam generated from the internal solution. Therefore, the product cannot be protected, and the product life will be shortened due to heat deterioration.

Further, in the device described in the above publication, since the water stop valve at the time of falling provided in the pouring passage is located in the inner container below the inner lid, the upper limit liquid level of the inner solution is If the setting is also made higher to increase the storage efficiency, the water shutoff valve will always be immersed in the internal solution when it falls, causing thermal deterioration.To avoid this, the upper limit liquid level should be set below the water shutoff valve when falling. If set, the storage efficiency will decrease.

Japanese Utility Model Laid-Open No. 60-91124 and Japanese Patent Laid-Open No. 58-67220 disclose a valve provided with a water stop valve at the time of tipping in both the pouring passage and the vapor vent passage. However, in both cases, the water stop valve at the time of falling of the pouring passage is lower than the lower surface of the lid that closes the vessel, and it is not possible to stop the water above the water stop valve at the time of falling of the content liquid. The structure of the water shutoff valve is complicated and expensive when it falls over in the steam vent passage.

An object of the present invention is to solve the above problems and to provide an electric hot water storage container which is capable of ensuring safety in the event of a fall and having excellent durability by improving the lid structure and the pouring path structure. The purpose is to do.

[0010]

In order to achieve the above-mentioned object, the electric hot water storage container of the present invention is accommodated in a lid body which is pivotally supported on a part of the upper portion of the body and can be opened and closed. A pouring passage for pouring out the inner solution in the inner container, which is passed between the container and the inner container, to the outside from the front of the container, and the opening and closing of the mouth of the inner container provided on the lower surface of the lid. A metal inner lid to be provided, and between the inner lid and the lid body, a vapor vent passage for discharging vapor generated from the inner solution to the outside from the rear portion of the lid body is provided, and the pouring passage is provided with the above-mentioned A fall stop water stop valve is provided in the pouring passage located near the height of the closed position of the inner lid, and a steam stop passage stop water stop valve is provided at one location of the steam release passage. It is a thing.

[0011]

According to the above construction of the electric hot water storage container of the present invention, the lid is opened and closed as a unit with the vapor vent passage around the pivot portion, and in the open state, the upper end of the container is opened and the inner container is opened at the same time. Since the entire mouth of the container is opened from the upper end of the container, it is possible to easily supply and discharge the internal solution and clean the inside of the container.In the closed state, the upper end of the container is closed and the inner container is closed by the inner lid. The mouth of the can be closed and the liquid content can be used in the state of storing hot water. Even if the internal solution is heated and vapor is generated, it is discharged to the outside of the lid through the vapor vent passage of the lid, and the vapor generated It is possible to prevent a risk that the oil is trapped in the inner container and abnormally increased in pressure to inadvertently push out the inner solution and spontaneously pour it out.

When the container falls, it is ensured that the liquid content from the pouring passage and / or the vapor vent passage will flow out by the water stop valve at the time of tipping provided in the pouring passage and the vapor vent passage. In particular, when the body falls to the front, the content liquid tries to flow out through the pouring passage only, and when the body falls to the rear, only through the steam vent passage. Also in this case, since the water shutoff valves at the time of fall provided in each of the pouring passage and the steam vent passage are closed by the fall of the container, it is possible to surely prevent.

Further, the metal inner lid is provided with a lid body, a steam vent passage provided between the lid body and the inner lid, and a falling water shutoff valve provided in the vapor vent passage in the inner container. Since the steam is constantly isolated and protected from the generated steam, it is possible to prevent these from being thermally deteriorated by the steam and shortening the life.

When the body 2 falls to the rear only through the pouring passage 7 which is the lower part of the inner solution, the inner solution tries to flow out only through the vapor vent passage 101 which is the lower part of the fallen body 2,
It is possible to surely prevent the water shutoff valves 51 and 29 at the time of fall provided in the spout passage 7 and the steam vent passage 101, respectively.

In particular, when the vessel 2 falls to the rear and the content liquid is about to flow out through the vapor drain passage 101 at the bottom, the water shutoff valve 29 at the time of tipping closes due to the tipping of the vessel 2. Since it is close to the outflow final position of the vapor vent passage 101, it is surely closed by its own weight before the content liquid to flow out arrives, and is pushed to the closed state by the content liquid that arrives after that, which is a conventional possibility. The content liquid reached before closing due to its own weight and part of the content liquid leaked out, or the pressure of the content liquid was neglected and the water stop valve 29 was made to dance when it fell, so that the content liquid cannot be immediately stopped. It is possible to eliminate the problems mentioned above, and the water stopping performance at the time of a fall is improved.

In addition, the water shutoff valves 51, 29 at the time of tipping are provided respectively with the pouring passage 7 and the vapor vent passage 10.
1, in the upper position of the front portion of the container body 2 of these pouring passages 7 and near the opening of the vapor vent passage 101 to the outside of the lid body 4,
It is located above the shoulder ring 15 and in the rear part of the lid 4, and exerts the water-stopping function, so that the spout passage 7 and the steam vent passage 10 are provided.
Even if there is dew condensation water or residual liquid in 1, it is possible to keep most of this in the pouring passage 7 or the vapor vent passage 101, and to prevent the outflow to the outside.

Further, since the water stop valve 29 at the time of the fall of the vapor vent passage 101 is located largely near the rear pivoting position of the lid 4, even if the lid 4 is vigorously closed, inertia and It is unlikely to be affected by the reaction, and it is possible to avoid accidentally closing the vapor vent passage 101.

Further, the spout passage 7 and the vapor vent passage 1
Since the water shut-off valves 51 and 102 of 01 are accommodated and held between the connection parts of the respective passages, no special member or work is required by utilizing the essential connection structure and work of the passages. Can be built in.

Particularly in the case of this embodiment, the steam vent passage 101
Since the water stop valve 29 for falling is provided near the pivot position of the rear portion of the lid 4 to the upper end of the body 2, and at a height substantially the same as this pivot position, 29 is located very close to the pivotal position of the lid 4, and the swing stroke when the lid 4 in this part is opened and closed is extremely small.
Since the inertia and reaction that occur even when the valve is vigorously closed is further suppressed, it is possible to reliably prevent the water stop valve 29 from sticking to the closed state during a fall.

The present invention can be constructed in various modes other than those shown in the above embodiments. For example, the means for attaching the inner lid 5 to the bellows lower plate 8 of the lid body 4 is not limited to the screw 25, and force fitting means or the like can be used.

The opening position of the discharge port 39 of the vapor vent passage 101 is not limited to that shown in each of the above embodiments, and the lid 4
It can also be set on the side wall.

According to the electric hot water storage container of the present invention, the lid is opened and closed as a unit together with the vapor vent passage around the pivot portion, and in the opened state, the upper end of the container is opened and at the same time the inner container is opened. Since the entire mouth is opened from the top of the body,
It is possible to easily supply and discharge the inner solution and clean the inner container.In the closed state, the upper end of the container is closed and the inner lid closes the mouth of the inner container to store the content liquid in the hot water state. Even if the internal solution is heated and vapor is generated, it can be used and discharged through the vapor vent passage of the lid to the outside of the lid. It is possible to prevent the danger of inadvertently pushing out the material naturally. When the body falls, the content liquid from the pouring passage or / and the vapor vent passage surely prevents the content liquid from flowing out by the water stop valve at the time of fall provided in the pouring passage and the vapor vent passage. In particular, when the container falls to the front, the content liquid tries to flow out only through the pouring passage, and when the container falls to the rear, only through the vapor discharge passage. Since the water stop valves at the time of falling provided in the pouring passage and the steam discharging passage are closed by the falling of the body, it is possible to surely prevent them.

The metallic inner lid is provided with a lid body, a steam vent passage provided between the lid body and the inner lid, and a fall-off water shutoff valve provided in the vapor vent passage in the inner container. Since the steam is constantly isolated and protected from the generated steam, it is possible to prevent these from being thermally deteriorated by the steam and shortening the life.
