Description

[Detailed description of the device]

[0001]

[Industrial applications]

 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 holding the container with a side handle or the like and tilting it.

[0002]

[Prior art]

 As shown in FIG. 3, this kind of electric hot water storage container is provided with a spout b to one side at the upper end of the body a and a lid d for closing the upper end opening c of the body a so that it can be opened and closed. The lid d is provided with a pouring path e which is in communication with the spout b in the closed state thereof and which is opened toward the inside of the container a, and a valve g which opens and closes the opening f. Has been.

This valve g has a valve rod h that vertically penetrates the spout passage e at the opening f, and this valve rod h is operated from the outside of the lid body d so that the valve disc i at the lower end of the valve rod h is operated. Is adapted to open and close the opening f.

Therefore, when the valve h is opened and the container a is tilted, the content liquid flows into the pouring passage 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 the liquid is not poured out to the outside.

By the way, since the content liquid is heated and boiled in the electric hot water storage container, 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 so that vapor generated in the vessel a can escape to the outside.

[0008] If the vapor vent passage j is simply provided, the content liquid will flow out to the outside when the container a falls, which is dangerous and has a disadvantage of wetting the surroundings.

Therefore, as shown in the figure, the vapor vent passage j is formed as a roundabout passage with one end opening on the lower surface of the lid d facing the inside of the vessel a and the other end opening on a part of the vapor vent passage j. The flow of the content liquid can be delayed.

By this, even if the body a falls, it is possible to take measures such as raising the body a before the content liquid flows out.

[0011]

[Problems to be solved by the device]

 However, since the vapor vent passage j has a simple curved shape in which the openings on both sides are connected by the soft resin pipe k of silicon rubber or the like, when the body a falls, the vapor vent passage j passes through the vapor vent passage. Is easy to leak to the outside, which is still a problem.

In order to solve this problem, the resin pipe k forming the vapor vent passage i is also made to have a small diameter.

However, in this case, a large amount of vapor when the content liquid boils is condensed in the resin pipe k, and this condensed water becomes a kind of faucet state and is pushed out to the pouring path by the vapor pressure and accumulates therein. However, it is inconvenient because the condensed water flows out when the body a is tilted in order to pour out the content liquid.

In addition, the thin soft resin pipe k is sometimes bent and closed for some reason during the assembly process. In this case, even if a large amount of steam is generated, it cannot escape, causing abnormal pressure rise. It is dangerous.

Therefore, an object of the present invention is to provide a handheld electric hot water storage container which can solve the above problems without making the structure particularly complicated by a simple improvement of the steam vent passage. Is.

[0016]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has a body having a spout on one side at the upper end, a lid for closing the upper end opening of the body, and a lid for closing the lid. In the closed state, one end side communicates with the spout, and the other end side has a spout provided so as to open toward the inside of the body, and a valve rod that vertically penetrates this spout at the opening. This valve rod is operated from the outside of the lid, and the valve body at the lower end of the valve rod is provided with a valve that opens and closes the opening.One end side of the valve rod and the valve rod is opened inside the body and the other end side is the pouring passage. The feature is that an open steam vent passage is provided, and a shut-off valve at the time of fall is provided in the middle of the steam vent passage, which is closed by the dead weight of the body and the pushing of the content liquid that is about to flow out.

It is preferable that an extension space is provided in the middle of the pouring path, and the other end side of the vapor vent passage is opened in the retention space.

[0018]

[Action]

 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 spout passage into the body, thereby injecting the content liquid by inclining the body through the spout passage. Can be stopped.

Even when the opening of the pouring path is closed, the vapor 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 vapor is opened in the body. Since 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, abnormal pressure rise in the body You can avoid that.

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 labyrinth in these structures, so that it is blocked during assembly. It is possible to reliably achieve the steam removal by avoiding such a situation, and it is possible to prevent the content liquid from flowing out through the steam removal passage to the outside when the body falls down. It can be delayed and delayed enough.

Accordingly, 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 body and in a heat-insulated state separated from the outside by the space of the lid body and the pouring passage so that the vapor vent passage becomes The temperature difference can be reduced.

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

If the pouring path has a pool space that is an extension of the opening of the vapor vent passage, even if the content liquid flows out through the vapor vent passage to the pouring path when the vessel falls, Once stored in the storage space, it is possible to further delay the outflow to the outside. Moreover, the expansion in the middle of the pouring path for the reservoir space can be formed without affecting the other by utilizing the wide space inside the lid.

A heater 11 is wound around the outer periphery of the bottom of the inner container 2 so as to heat the content liquid, to boil water and to retain heat. A heat insulating material 12 is wrapped around the body of the inner container 2 to prevent heat from escaping to the outside.

As a result, the heat efficiency of boiling water and heat retention is improved, and it is possible to prevent a part of the outer case 1 from becoming hot due to heat radiation.

The heater 11 may be attached to the lower surface of the bottom of the inner container 2, or when the boiling water heater and the heat retention heater are used separately, the respective attachment positions may be changed.

At the front part of the portion where the shoulder member 4 forms the mouth portion 3a of the body 3 that is continuous with the mouth portion 2a of the inner container 2, the spout 13 to the one side of the upper end of the body 3 is provided. It is integrally formed as a beak-shaped projection that projects forward from the mouth 3a of the body 3 in a gutter shape, and is communicated with the mouth 2a of the inner container 2 through the mouth 3a of the body 3.

A side handle 14 is integrally formed at the rear portion of the shoulder member 4 so as to be continuous at the upper end thereof.

The lower end of the side handle 14 is applied to the outer surface of the lower end of the outer case 1, and is fixed by a screw 15 from the inside of the outer case 1.

Thus, by holding the side handle 14 by hand, the body 3 can be handled freely, and the body 3 can be tilted in order to pour out the content liquid.

As shown in detail in FIG. 2, a cover plate 16 is provided at the base of the spout 13 and a flap valve 17 is provided at the tip. The flap valve 17 is pivotally supported by a shaft 18 below the cover plate 16 so as to be kept closed by an urging force of a spring 19.

A lid 21 is detachably fitted to the mouth 3a of the body 3 by a screw fitting portion 22, and by removing this, the mouth 3a of the body 3 and the mouth 2a of the inner container 2 are removed. It is opened so that water or the like can be put into the inner container 2.

The lid 21 is made of a resin-made main body case 22 that fits into the mouth portion 3 a of the body 3, and a head case 23 that is placed on the body case 22 from above and is located above the body 3. And are formed in the hollow.

A heat shield cover 24 made of metal is applied to the bottom 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 3 a of the body 3, the heat shield cover 24 is attached. By facing the inside of the inner container 2, even if a large amount of high-temperature vapor 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 limitation. 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 into the mouth portion 3a of the container body 3a up to the regulation position, the seal packing 26 is crimped onto the mouth portion 2a of the inner container 2 to close the contents container 2. ing.

It should be noted that 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 content liquid through the inside of the lid body 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, while having a valve rod 33a that vertically penetrates the pouring path 31 at the opening 30, the valve rod 33a is operated from the outside of the lid body 21 so that the valve body 33b at the lower end of the valve rod 33a is opened. A valve 33 is provided in the main body case 22 for opening and closing by contacting and separating a seal packing 40 in which 30 is fitted to the outer peripheral portion, so that the spout passage 31 can be opened and closed as appropriate.

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

A pool space 36 is formed in the middle of the pouring path 31 so as to expand, and the other end of the vapor vent passage 35 is opened at the opening 35a in the reservoir space 36. In the middle of 35, a water stop valve 37 at the time of fall is provided 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 of the valve rod 33a and the valve body 33b, a valve chamber 39 accommodating the fall-stop water valve 37 is formed slightly larger by utilizing the expansion of the storage space 36, and when it falls inside, It has a rib 39a for guiding the water shutoff valve 37, and a steam vent passage 35 from an opening 35b into the inner container 2 on one end side to an opening 35a to a reservoir space 36 on the other end side, and a valve rod 33a. The shape of the valve body b and the valve chamber 39, the presence of the water shutoff valve 37 at the time of fall, and the orientation of the openings 35a and 35b can be formed into a complicated detouring maze, which can be used alone. When the body 3 falls, it prevents the content liquid from flowing out through the vapor vent passage 35 and can be sufficiently delayed. However, since the water stop 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 that guides a valve rod 33a penetrating therethrough so as to be vertically moved in a stable manner is integrally formed on a ceiling portion 36a of a reservoir space 36 formed by the main body case 22. A seal packing 39, which is in sliding contact with the inner circumference of the bearing cylinder 38, is mounted on the outer peripheral portion of the bearing cylinder 38 to prevent leakage of the content liquid through the bearing cylinder 38.

A head portion 33c is attached to the upper end of the valve rod 33a by a screw 41, and a spring 42 works between the head portion 33c and the ceiling portion 36a of the body case 22 to open the valve body 33b. It is urged to always close 30.

The head case 23 of the lid body 21 has a downwardly facing cylindrical wall 43 opening in the center thereof, and a press button 44 is fitted into the cylindrical wall 43 so as to be vertically movable from below, and the cylindrical wall 43 is inserted. The downward step portion 43a of the inner surface of the lid prevents the upper portion from coming off, and at the retaining position by the step portion 43a, the pressing button 44 is exposed to the upper surface of the lid body 21 in a substantially flush manner. It can be pushed in from the outside.

Further, the head portion 33c of the valve rod 33a is fitted to the cylindrical wall 43 so as to be vertically movable from below, and an attitude holding mechanism 51 is configured between the outer peripheral portion of the head portion 33c and the pressing button 44. is doing.

The posture holding mechanism 51 holds the head portion 33c in the upper moving position and the lower moving position each time the pressing button 44 is pressed, and the valve body 33b moves the valve head 33c through the valve rod 33a. The valve 33 is alternately held in the open state and the closed state.

The body case 22 is provided with an operating member 52 which is freely movable in the front-back direction of the body 3. The operating member 52 has a pushing piece 52a facing the tail end portion 17a of the flap valve 17 through a hole 53 provided in the front portion of the main body case 22, and the pushing piece 52a is moved by a spring 54. It is urged so as to maintain the retracted position where it does not come into contact with.

The operation member 52 has a cam surface 52b facing the lower side of the head portion 33c at the rear part, and the cam surface 52b is pushed by the downward movement of the head portion 33c when the valve 33 is opened to move forward. It is pushed out and pushes the tail end portion 17a by the pushing piece 52a to push the flap valve 17 against the spring 19 so that the liquid content can be poured out.

An intake passage 55 is provided which extends rearward from the reservoir space 36 of the spout passage 31 and opens on the outer peripheral surface of the rear portion of the main body case 22. When the content liquid 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 sucked in. This prevents a negative pressure in the inner container 2 due to the pouring out of the content liquid, which causes a pulsation in the pouring out of the content liquid or the inability to pour out.

In short, with the above configuration, the valve 33 is operated from the outside of the lid body 21 to open and close the opening 30 of the dispensing path 31 into the inner container 2 in the body 3, whereby the dispensing path is opened. It is possible to inject the content liquid by tilting the body 3 through 31 and prevent this.

Even if the opening 31 of the pouring path 31 is closed, the vapor 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 is a body. 3 is opened to the inside of the container 2 and communicates therewith, and the other end side is opened to the spout passage 31 and exits to the spout passage 31 via the vapor vent passage 35 that communicates therewith, and the spout 13 is communicated from the spout passage 31. Since it is discharged to the outside through the steam discharge hole 61 of the flap valve 17, it is possible to avoid an abnormal increase in pressure in the inner container 2 inside the container 3.

Since the vapor vent passage 35 is provided in the valve body 33b and the valve rod 33a of the valve 33 and is formed with sufficient rigidity in any maze in these structures, it is assembled. It is possible to prevent the upper vapor vent passage 35 from being blocked and to reliably achieve the vapor discharge, and when the body 3 falls, the content liquid tries to flow out to the outside through the vapor vent passage 35. This can be obstructed by the maze-shaped vapor vent passage 35 and delayed to a sufficient extent.

Further, as a result, it is not necessary to make the vapor vent passage 35 extremely thin, and the vapor vent passage is located near the inside of the container 3, particularly inside the inner container 2, and from outside the lid 21 and the pouring passage 31. 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 separated by a space, condensation of steam in the steam removal passage 35 and condensation water resulting therefrom It is possible to avoid the fact that the water becomes a faucet and is 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 passage 31 through the vapor vent passage 35 when the vessel 3 falls. Even if it does, since it is temporarily stored in the storage space 36, it is possible to further delay the outflow to the outside. 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 21 without affecting 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. Therefore, the content liquid can be more reliably prevented 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]

[Effect of device]

 According to the present invention, when the pouring passage is closed, the vapor vent passage that releases the vapor generated by the heating and boiling of the content liquid to the outside to prevent abnormal pressurization is provided in the valve body of the valve that opens and closes the pouring passage. It is installed in the valve rod and is formed with sufficient rigidity in any maze in these structures, and it prevents vaporization passages from being blocked during assembly and ensures vapor extraction. Therefore, it is possible to ensure a high degree of safety, and when the body falls, the vapor discharge passage in a maze state interferes with the delay of the content liquid trying to flow out through the vapor discharge passage sufficiently. Therefore, it is easy to take measures in case of a fall and to use safely.

Accordingly, 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 body and in a heat-insulated state separated from the outside by the space of the lid and the pouring passage so that the vapor vent passage becomes Since the temperature difference between the two is reduced, it is possible to prevent the condensation of steam in the steam vent passage and the condensation water resulting from the condensation water being pushed into the spout path due to the faucet state. The inconvenience of dew condensation water flowing out is eliminated.

In addition, when the vessel falls, the water stop valve provided in the vapor vent passage is closed by being pushed by the content liquid that is about to flow out due to its own weight or through the vapor vent passage, and the content liquid passes through the vapor vent passage. It is possible to almost completely prevent the risk and inconvenience that the content liquid will flow out, and the stop valve at the time of tipping is used in the structure of the valve body and the valve rod. It has the advantage that it can be installed without difficulty by using the space in and around the spouting channel without affecting others, 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, Once stored in the storage space, the flow to the outside is further delayed, making it easier to use safely. Moreover, since the expansion in the middle of the pouring path for the pool space is formed without any other effect by utilizing the large space inside the lid, there is an advantage that the structure is not complicated or large.
