[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric hot water storage container, such as a simple electric pot for household use, in which the content liquid can be poured out by hand-holding and tilting the container with a side handle or the like.

[0002]

2. Description of the Related Art As shown in FIG. 3, an electric hot water storage container of this type is provided with a spout b on one side at the upper end of a body a and is capable of opening and closing an upper end opening c of the body a. The lid d has a closing body, and the lid body d is opened and closed so as to communicate with the pouring outlet b in the closed state and open toward the inside of the vessel a. A valve g is provided.

The valve g has a valve rod h that vertically penetrates the spout passage e at the opening f, and the valve rod h is operated from the outside of the lid d so that the valve rod i at the lower end of the valve rod h is opened. The opening f is opened and closed.

Therefore, when the valve h is opened and the vessel a is tilted, the content liquid flows into the pouring path e through the opening f, reaches the pouring outlet b, and is poured out to the outside.

When the valve g closes the opening f, the content liquid cannot flow into the pouring path e even if the body a is tilted, so that it cannot be poured out to the outside.

By the way, in the electric hot water storage container, since the content liquid is heated and boiled, a large amount of steam is generated. Therefore, if the lid body d completely closes the upper end of the body a, the pressure inside the body a can be abnormally increased.

In order to solve this, a vapor vent passage j is provided in a part of the lid body d for letting the vapor generated in the vessel body a escape to the outside.

If the vapor vent passage j is simply provided, the liquid content will flow out to the outside when the container a falls, which is dangerous and has the disadvantage of wetting the surroundings.

Therefore, as shown in the figure, the vapor vent passage j is formed as a roundabout passage having one end open on the lower surface of the lid d facing the vessel a and the other end open on a part of the vapor vent passage j. In this way, the outflow of the content liquid can be delayed.

Thus, even if the body a falls, it is possible to take measures to raise the body a before the content liquid flows out.

[0011]

However, since the vapor vent passage j has a simple curved shape in which the openings on both sides are connected by a soft resin pipe k such as silicone rubber, when the body a falls down, It is still a problem because the content liquid easily flows out through the steam vent passage.

In order to solve this, the vapor vent passage i
It is also practiced to make the resin pipe k for forming a small diameter.

In this case, however, a large amount of vapor when the content liquid boils condenses in the resin pipe k, and this condensed water becomes a kind of faucet and is pushed out to the pouring passage by the vapor pressure and accumulates. If the container a is tilted in order to pour out the content liquid, this dew condensation water will flow out, which is inconvenient.

It is sometimes the case that the thin soft resin pipe k is bent and clogged for some reason during the assembly stage. In this case, even if a large amount of steam is generated, it will not escape, causing abnormal pressure rise. Very dangerous.

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a hand-held electric hot water storage container which can solve the above-mentioned problems without making the structure particularly complicated by a simple improvement of the steam vent passage. is there.

[0016]

In order to achieve the above-mentioned object, the present invention closes a container having a spout to one side at the upper end and an upper end opening of the container so as to be opened and closed. The lid body, a pouring path provided in the lid body such that one end side communicates with the pouring opening in the closed state and the other end side opens toward the inside of the container, and the pouring path is vertically moved through the opening. The valve rod has a valve rod penetrating the valve rod and the valve rod at the lower end of the valve rod opens and closes the opening by operating the valve rod from the outside of the lid body. A steam vent passage whose end is open to the pouring passage is provided, and a shut-off valve at the time of tipping is provided in the middle of the vapor vent passage, which is closed by its own weight when the body falls and pushing of the content liquid that is about to flow out. It is what

A pool space is provided by expanding the middle of the pouring path,
It is preferable that the other end of the vapor vent passage is opened in this pool space.

[0018]

In the above configuration of the present invention, the valve is operated from the outside of the lid to open and close the opening of the pouring path into the body, thereby pouring the content liquid by tilting the body through the pouring path. Moreover, this can be prevented.

Even if the opening of the pouring path is closed, the steam generated by the heating and boiling of the content liquid is provided in the valve body and the valve rod of the valve, and one end of the steam is opened into the body and communicates therewith. , The other end opens to the spout passage and exits to the spout passage through the vapor vent passage that leads to this, and is discharged to the outside from the spout passage through the spout that communicates with it, causing abnormal pressure rise in the body. Can be avoided.

The steam vent passage is provided in the valve body and the valve rod of the valve and is formed with sufficient rigidity in any maze in these structures, so that it may be closed during assembly. It is possible to reliably achieve steam removal by avoiding this, and when the vessel falls, it prevents the content liquid from flowing out to the outside through the steam removal passage in the maze state steam removal passage. Can be delayed enough.

Therefore, it is not necessary to make the vapor vent passage extremely thin, and the vapor vent passage is provided near the body and in an adiabatic state separated from the outside by the space of the lid body and the pouring passage so that the vapor vent passage is The temperature difference can be reduced.

Further, if a water shutoff valve is provided in the vapor vent passage when it falls, the valve is closed by its own weight or when pushed by the content liquid that is about to flow out through the vapor vent passage. It is possible to more reliably prevent the liquid from flowing out through the vapor vent passage. The water shut-off valve at the time of falling can be easily provided without any other influence by utilizing the space in the structure of the valve body of the valve and the valve rod and in the surrounding spout passage.

If the pouring path has a pool space in which the opening of the vapor vent passage is expanded, even if the content liquid flows out to the pouring channel through the vapor vent passage when the vessel falls, it is temporarily removed. Since it is stored in the storage space, it is possible to further delay the outflow to the outside. In addition, the expansion in the middle of the pouring path for the reservoir space can be formed without affecting others by utilizing the wide space inside the lid.

A heat shield cover 24 made of metal is attached to the lower surface of the bottom of the main body case 22 and attached by screws 25. When the lid body 21 is fitted into the mouth portion 3a of the body 3, the heat shield cover 24 is attached. By facing the inner container 2 with each other, even if a large amount of high-temperature steam is generated from the content liquid heated in the inner container 2, the main body case 22 is prevented from being directly exposed to this without limit. The case 22 is prevented from being thermally deteriorated.

A seal packing 26 fitted on the outer periphery of the heat shield cover 24 is sandwiched between the bottom of the main body case 22 and the outer periphery of the heat shield cover 24, and the lid 21 is attached to the mouth of the body 3. When the lid body 21 is correctly fitted to the mouth portion 3a of the container body 3a up to the regulation position, the seal packing 26 is pressed onto the mouth portion 2a of the inner container 2 to close the inner container 2. ing.

The heat shield cover 24 is provided with elongated openings 27 at the front and rear so as not to obstruct the pouring of the liquid content through the lid 21.

In order to pour out the content liquid through the inside of the lid body 21 in the main body case 22, one end side communicates with the spout 13 and the other end side is a container when the lid body 21 is properly closed. A pouring path 31 is integrally formed so as to have an opening 30 facing the inside of the inner container 2 of the body 3.

Further, there is a valve rod 33a which vertically penetrates the pouring path 31 at the opening 30, and the valve rod 33a is operated from the outside of the lid body 21 so that the valve rod 33a at the lower end of the valve rod 33a.

In the valve body 33b and the valve rod 33a, there is provided a vapor discharge passage 35, one end of which opens in the inner container 2 of the container 3 through the heat shield cover 24 and the other end of which opens to the pouring passage 31. . The flap valve 17 is provided with a steam discharge hole 61.

A pool space 36 is provided in the middle of the pouring path 31 so as to expand, and the other end of the vapor vent passage 35 opens in the reservoir space 36 at an opening 35a. A water stop valve 37 at the time of fall is provided in the middle of the time, which is closed by its own weight at the time of fall and the pushing of the content liquid that is about to flow out. However, these are not essential and may be adopted as needed.

At the fitting portion between the valve rod 33a and the valve body 33b, a valve chamber 39 for accommodating the fall stop water valve 37 is formed to be slightly larger by utilizing the expansion of the storage space 36, and the inner surface is prevented from falling. The steam vent passage 3 has a rib 39a for guiding the water valve 37 and extends from the opening 35b into the inner container 2 on one end side to the opening 35a to the reservoir space 36 on the other end side.
5 can be formed in a labyrinth that detours intricately, including the shape of the valve rod 33a, the valve body b and the valve chamber 39, the presence of the water stop valve 37 at the time of falling, and the orientation of the openings 35a and 35b. Even by this alone, the outflow of the content liquid through the vapor vent passage 35 when the container 3 falls can be obstructed and delayed sufficiently. However, since the water shutoff valve 37 at the time of falling can prevent the content liquid from flowing out, and even if it flows out, the amount can be made small, it is preferable to use it together.

A bearing cylinder 38 is integrally formed with the ceiling 36a of the reservoir space 36 formed by the main body case 22 to guide the valve rod 33a passing therethrough so as to be stably moved up and down. A seal packing 39 which is slidably contacted with the inner circumference of the bearing cylinder 38 is mounted on the outer peripheral portion of the bearing cylinder 38.
It prevents the content liquid from leaking through.

A head 33c has a screw 4 at the upper end of the valve rod 33a.

An intake passage 55 extending rearward from the pool space 36 of the pouring passage 31 and opening to the outer peripheral surface of the rear portion of the main body case 22.
Is provided. When the liquid content is poured out, the intake passage 55 introduces outside air through the gap between the lid 21 and the mouth 3a of the container 3, and this introduces the outside air through the outlet 31 and the vapor vent passage 37. It is designed to be inhaled inside. This prevents the content liquid from being poured into a negative pressure in the inner container 2 and causing pulsation in the content liquid to be dispensed or the inability to dispense.

In short, the valve 3 has the above-mentioned structure.
3 is operated from the outside of the lid body 21 to open and close the opening 30 of the pouring path 31 into the inner container 2 in the vessel 3, so that the content liquid is poured out through the pouring path 31 by tilting the vessel 3. And can prevent this.

Even if the opening 31 of the pouring path 31 is closed, the steam generated by the heating and boiling of the content liquid is provided in the valve body 33b and the valve rod 33a of the valve 33, and one end side of the body 3 is provided. A steam vent passage 3 that opens into the inner container 2 and communicates therewith, and the other end side opens into the spout passage 31 and communicates therewith.
5 to the spout passage 31 and the steam discharge hole 61 of the flap valve 17 through the spout 13 which communicates from the spout passage 31.
Since it is discharged from the inside to the outside, it is possible to avoid abnormal pressure increase in the inner container 2 in the container 3.

The vapor vent passage 35 has a valve body 33b of the valve 33.
Also, since it is provided in the valve rod 33a and has sufficient rigidity in any maze in these structures, it is possible to prevent the steam vent passage 35 from being blocked during assembly. Of the vapor can be reliably achieved, and when the body 3 falls, the content liquid is removed from the vapor vent passage 35.
It is possible to sufficiently delay the flow of the gas through the maze-shaped vapor vent passage 35 so that it will not flow out to the outside.

Further, by this, it is not necessary to make the vapor vent passage 35 extremely thin, and the vapor vent passage is formed by the space of the lid body 21 and the pouring passage 31 from the outside, particularly near the inner container 2 of the container 3. Since the temperature difference between the container 3 and the atmosphere in the inner container 2 in particular can be reduced by providing them in a heat-insulated state, the dew condensation of the steam in the steam vent passage 35 and the dew condensation water resulting from it can be regarded as a faucet state. Therefore, it is possible to avoid being pushed out by the vapor pressure.

Since the pouring path 31 has a pool space 36 in which the opening of the vapor vent passage 35 is expanded, the content liquid flows out to the pouring path 31 through the vapor vent passage 35 when the vessel 3 falls. Even if it does, since it is once stored in the storage space 36, the outflow to the outside can be further delayed. Moreover, the expansion in the middle of the pouring path 31 for the reservoir space 36 can be formed by utilizing the large space in the lid body 21 without affecting the others.

Since the vapor stop passage 35 is provided with the water stop valve 37 at the time of tipping, the valve 37 is pushed by its own weight or by the content liquid which is about to flow out through the vapor vent passage 35 when the vessel 3 falls. Since it is closed, it is possible to more reliably prevent the content liquid from flowing out through the vapor vent passage 35. The water stop valve 37 at the time of falling can be provided without difficulty by utilizing the space in the structure of the valve body 33b of the valve 33 and the valve rod 33a and in the surrounding spout passage 31 without any other influence.

[0060]

According to the present invention, when the pouring passage is closed, the vapor vent passage for releasing the vapor generated by the heating and boiling of the content liquid to the outside to prevent abnormal pressurization is a valve for opening and closing the pouring passage. It is installed in the valve body and the rod of the vehicle, and is formed with sufficient rigidity in any maze in these structures, so that the steam vent passage is prevented from being blocked during assembly, and steam is removed. This ensures a high degree of safety, and prevents the content liquid from flowing out to the outside through the vapor vent passage when the body falls, by the vapor vent passage in the maze state. Since it can be delayed for a long time, it is easy to take measures in case of a fall and to use safely.

Therefore, it is not necessary to make the vapor vent passage extremely thin, and the vapor vent passage is provided closer to the inside of the vessel and in a heat-insulated state separated from the outside by the space of the lid body and the pouring passage to establish an atmosphere inside the vessel. Since the temperature difference between the two is reduced, it is possible to avoid condensation of steam in the steam vent passage, and to prevent the condensed water from being condensed into a faucet and pushed out to the pouring path. The inconvenience of dew condensation water flowing out is eliminated.

In addition, when the vessel falls, the water shutoff valve provided in the vapor vent passage is closed by being pushed by the content liquid which is about to flow out by its own weight or through the vapor vent passage, and the liquid content is removed from the vapor vent passage. It is possible to almost completely prevent the risk and inconvenience of the content liquid flowing out by further suppressing the outflow through the valve.In addition, the water shutoff valve at the time of tipping is provided in and around the valve body of the valve and the structure of the valve rod. It has the advantage that it can be easily installed without any other influence by utilizing the space in the pouring path, and does not complicate or upsize the structure.

If the pouring path has a pool space where the opening of the vapor vent passage is expanded, even if the content liquid flows out to the pouring channel through the vapor vent passage when the vessel falls, it is temporarily removed. Since it is stored in the storage space and the outflow to the outside is further delayed, it is possible to further facilitate safe use. Moreover, since the expansion in the middle of the pouring path for the pool space is formed without affecting the other by utilizing the wide space inside the lid, there is an advantage that the structure is not complicated or large.
