BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steam passage device for an electric hot water storage container, and more particularly to a cover for opening and closing a container body, which discharges steam generated from a content liquid heated in the container body to the outside. The present invention relates to a steam passage device for an electric hot water storage container having a water shut-off valve at the time of overturning, which prevents spontaneous pressurization and prevents the content liquid from flowing out through the steam passage when the body falls over.

[0002]

2. Description of the Related Art A steam passage device of this type will be described with reference to FIG. 1 showing an embodiment of the present invention. The rear part of the steam passage device pivots on a shoulder portion of the container 1 by a hinge pin 68 so as to open and close the container 1. The supported vessel lid 6 is provided with a steam passage 87 for discharging the steam generated in the vessel 1 to the outside.
The steam outlet 86 from the inside is opened at a position apart from the pivotal support portion of the body lid 6 toward the front side, and the steam passage 8
7, the steam outlet 52 to the outside of the body lid 6 is opened to the outer surface of the body lid 6 along a path 87a passing near the pivotal portion of the body lid 6, and the steam passage 87 is in the middle when the body 1 falls. Valve opening 105
Has a structure in which a water shutoff valve 106 at the time of overturning, which is closed by its own weight or the pushing of the outflow content liquid, is provided in the steam passage 87 near the outlet 86.

As shown in FIG. 1, the steam outlet 86, which is opened at a position distant from the pivot portion of the body lid 6 toward the front side, is located substantially in the center of the body lid 6 and the body 1 is Even if it falls to the opposite side, if the remaining amount of the content liquid is less than half, it can be in a position where the content liquid does not easily flow out. Due to the structure of the passage in which the steam outlet 52 for the outside 6 is open to the outer surface of the vessel lid 6, the length of the path from the outlet 86 of the steam passage 87 to the outlet 52 can be made large. It is possible to delay the time until the content liquid 1 flows over to the outside of the vessel lid 6 through the vapor passage 87 due to the tipping over, and it is easy to have a margin to take measures before the content liquid flows to the outside.

Further, the water shutoff valve 106 at the time of tipping is provided with the outlet 8
6 is provided in the vicinity of 6, the content liquid that is about to flow out through the steam passage 87 when the body 1 falls down
Can be prevented at the initial outflow position, which is advantageous in preventing outflow to the outside.

[0005]

By the way, the body lid 6 is
In the open state, the rear side is slightly tilted so as to be stable. For example, with the body lid 6 left open, the body 1
There is no inconvenience that the body lid 6 is inadvertently closed when the content liquid is put into the inside.

However, in order to close the container lid 6 which is stable in this open state, it is sometimes performed to strongly close it by a momentary or abrupt pushing operation.

[0007] In this case, when the valve opening 105 provided near the outlet of the vessel lid 6 moves at a large moving speed in the closing direction of the vessel lid 6, the water shutoff valve 106 at the time of falling falls by its own inertia. Portions 105 are partially fitted and crimped, and the inner container 31 is kept in a crimped state due to the imbalanced state of the internal and external pressures, that is, the internal pressure becomes a high pressure, and the pressure inside the inner container 31 is abnormally increased, It has been said that the content liquid is inadvertently pushed out by a discharge type electric pot.

According to the present invention, the above-mentioned problems of the prior art can be solved by achieving detour ventilation at the water shut-off valve 106 at the time of falling while sufficiently preventing the content liquid from flowing out in the steam passage 87. An object of the present invention is to provide a steam passage device for an electric hot water storage container that can be used.

[0009]

In order to achieve the above object, the present invention provides a steam for discharging steam inside a container to a lid body whose rear part is pivotally supported by the container so as to open and close the container. A passage is provided, and the steam outlet from the body of the steam passage is opened at a position distant from the pivotal portion of the lid body to the front side, and the steam outlet to the outside of the lid of the steam passage is provided in the lid body. Open the outer surface of the lid by a route that passes through the vicinity of the pivot, and when the body falls, close the valve opening in the middle of the steam passage by its own weight or by pushing the spilled content liquid. In a steam passage device for an electric hot water storage container provided near an outlet, a notch serving as a bypass ventilation part for a shutoff valve in a closed state is provided at a rim of the valve opening, and a pivot portion of the lid body of the steam passage is provided. In the path part that passes nearby, the valve opening and the valve opening when the body falls It is characterized in the provision of the heavy and closed by pushing the effluent liquid content assist the fall waterproofing valve.

It is preferable to form a liquid pool in which the passage is expanded at a portion of the steam passage between the water shutoff valve at the time of fall and the water shutoff valve at the time of auxiliary fall.

[0011]

According to the above construction of the present invention, the steam outlet from the container body of the steam passage provided in the lid so that the steam generated from the content liquid in the container escapes to the outside. The water stop valve at the time of fall, which is located away from the pivotal part to the body on the front side, is installed near the outlet and is large in the direction of closing the lid at the valve opening when the lid is closed suddenly. Even if there is a case where it is pressed against the valve opening due to its own inertia with respect to the moving speed,
The cut on the rim of the valve opening forms a bypass air passage around the water shutoff valve at the time of fall, and the water cutoff valve sticks to the valve opening at the time of fall, and the internal / external pressure unbalanced state, that is, the internal pressure tends to be high pressure. It is possible to prevent the pressure inside the body from being naturally increased due to the influence of the above.

Then, in order to open the steam outlet to the outside of the steam passage to the outside of the lid body, the auxiliary water stop valve at the time of fall and the auxiliary water stop valve provided in the passage portion near the pivotal support portion of the lid body. Since the cooperating valve opening is close to the pivot of the lid, even when the lid is suddenly closed, the valve opening does not have a large moving speed in the closing direction of the lid. Only a small inertia acts on the water valve, and it is possible to prevent it from being crimped to the valve opening, and avoiding spontaneous pressurization due to mutual contact with the valve opening without cutout, to the outside of the content liquid. It is possible to prevent the outflow and to delay the outflow of the content liquid between the water stop valve at the time of fall and the water stop valve at the time of auxiliary fall, and at the same time, it is formed by the cut at the water stop valve at the time of fall. It is sufficient to make up for the fact that the bypass ventilation part becomes a slight outflow part for the content liquid. Kill.

Further, if a liquid pool having a widened passage is formed between the water stop valve at the time of the fall of the steam passage and the water stop valve at the time of the auxiliary fall, the content liquid overflows beyond the portion of the water stop valve at the time of the fall. Even if this happens, the outflow of the content liquid to the outside can be further delayed while the content liquid is stored in the liquid pool.

A valve opening 612 is provided in the portion 7a, and an auxiliary water stop valve 613 is provided below the valve opening 612 to close the valve opening 612 by pushing due to its own weight or content liquid when the body 1 falls down. With the water shutoff valve 106, it is easier to prevent the content liquid from flowing out through the steam passage 87 when the container 1 falls.

In the present embodiment, the cutouts 614 are formed at several positions on the opening edge of the opening 105 closed by the water shutoff valve 106 at the time of overturning in order to utilize the safety against the outflow of the content liquid. Therefore, when the vessel lid 6 is suddenly closed, in the conventional case where there is no such cut 614, the water shutoff valve 106 at the time of fall is partially fitted into the opening 105 by its own inertia and is crimped. There is a case where the pressure is unbalanced, that is, the internal pressure is kept high due to the influence of a high pressure, and the inside of the inner container 31 is naturally pressurized. By doing so, it is possible to avoid the close contact and the close contact being maintained, and prevent the spontaneous pressurization as described above from occurring.

In FIG. 6, the flow of compressed air at the time of air supply is indicated by the solid line arrow, and the flow of steam at the time of vapor discharge is indicated by the broken line arrow. A hot water storage unit 615 is provided between the respective installation portions of the water shutoff valves 106 and 613 at the time of fall of the steam passage 87.
Is provided, and when the content liquid tries to flow out through the steam passage 87 due to the notch 614 or the like when the container 1 falls, it temporarily stores this and prevents it from flowing out to the next,
I'm trying to delay it. In addition, the bypass path 8 that lengthens the length of the steam passage 87 from the water stop valve 106 at the time of fall to the water stop valve 613 at the time of auxiliary fall to further delay the outflow of the content liquid.
7b is also formed by the partition peripheral wall 104a.

A return port 616 is provided for returning the content liquid that has flowed out or has condensed to the steam passage 87 when the container lid 6 is opened, to the return port 616. A seal packing 617 is attached to contact the inner peripheral surface of the shoulder member 32 of the inner container 31 to close the return port 616 while the body lid 6 is closed.

Also, the upper plate 111 of the bellows pump 101.
As shown in FIG. 3, a resin-made intake valve 211 is provided in a part of the above, so that when the bellows pump 101 is restored after being pressed, the intake valve 211 is opened so that outside air can be sucked through the intake port 212. ing. At this time, the intake port 212 is located far from the inside of the inner container 31 of the bellows pump 101 and close to the outside so that cold air can be easily sucked. Therefore, when the bellows pump 101 is next pressed, the expansion of the air when the air in the bellows pump 101 is blown into the inner container 31 can be expected greatly, and the pressurization efficiency of the content liquid can be improved. it can.

A pouring lock member 122 is provided around the portion of the vessel lid 6 where the pressing plate 102 is provided to prevent the pressing plate 102 from being pushed down by the rotating position and to release the blocking. The operation protrusion 122a protruding from the upper surface of the body lid 6 is used for operation.

Further, as shown in FIGS. 1 and 5, the inner container 31
A magnet 621 is attached to a part of the front surface of the body of the presser fitting 62.
The purifier 623 is attached by the magnet 621 to the inner surface of the inner container 31 corresponding thereto.

Specifically, the purifier 623 is held on the inner surface of the body of the inner container 31 by the metal case 624 being attracted by the magnet 621. And
A resin grid-like lid 625 is fitted to the mouth of the metal case 624, and a porous purification material case 626 is detachably fitted to the back surface of the lid 625.

A purifying material such as activated carbon or ceramic is contained in the purifying material case 626, and the lid 625 or the purifying material case 6 is contained.
Since the content liquid permeates and passes through the purification material through the grids and porous portions of 26 and comes into contact with this purification material, the content liquid is purified into hot water to remove odors and harmful chlorine compounds such as trihalomethanes. You can

Moreover, since the content liquid is actively convected by heating, particularly by boiling, it is possible to promote the passage of the content liquid to the purifying material and to purify the entire content liquid evenly.

In addition to such a purifying action, the control circuit 42 makes the content liquid boil for a predetermined time at a predetermined time or at a predetermined time, or by repeating the boiling, to emit an odor or a harmful substance. Can be used together.

The purifier 623, which is in the inner container 31 and is in contact with the content liquid, can be taken in and out of the container 1 together with the inner container 31 and the content liquid discharge passage 33, and the inner container 31 can be connected to the container 2. It is possible to easily clean the purifier 263 itself regardless of the side of the container body 1 in addition to not impairing the taking in and out. Particularly, in this embodiment, since the purifier 623 is held on the inner surface of the inner container 31 by the attraction force of the magnet 621, the purifier 623 can be easily removed only by overcoming this attraction force.
It is advantageous that the cleaning itself can be handled individually and very easily performed.

Further, a skirt-shaped cylindrical wall 627 is forcibly fitted and mounted on the lower outer periphery of the inner container 31.
It is designed so as to extend below the bottom of the unit 1. This prevents the bottom of the inner container 31 from directly contacting the stationary surface or being deformed due to external force during handling even when the inner container 31 is pulled out from the body 1 and directly placed. Therefore, it is possible to avoid the occurrence of poor contact with the heating plate 8 due to the deformation.
When the inner container 31 is placed on the hot platen 8, the cylindrical wall 6
27 covers the outer periphery of the heating platen 8 as shown in FIGS. 1, 4 and 5, so that the heat from the heating platen 8 can be effectively used to heat the content liquid in the inner container 31 and the thermal efficiency is improved. improves.

According to the present invention, when the lid is closed suddenly, it cooperates with the valve opening for a large moving speed in the lid closing direction depending on the position condition of the valve opening on the lid. Even if the water shutoff valve at the time of a fall may be crimped to the valve opening due to its own inertia, the detour ventilation around the water shutoff valve at the time of the fall formed by the notch provided at the rim of the valve opening causes a fall. Prevents the temporary stop valve from sticking to the valve opening and maintaining the crimping state due to the imbalanced state of the internal and external pressure, that is, the internal pressure becoming high pressure, which causes the internal pressure of the vessel to rise naturally. Therefore, it is possible to prevent abnormal pressurization of the inside of the body or inadvertently pushing out the content liquid in the pressurized pouring type electric hot water storage container, thus improving the safety of use.

In order to open the steam discharge port to the outside of the lid, the auxiliary water stop valve at the time of fall provided in the route portion passing near the pivotal support portion of the lid of the steam passage, and in cooperation with this valve. Since the valve opening is close to the pivot of the lid, even when the lid is suddenly closed, a large moving speed in the closing direction of the lid is generated at this valve opening, and the stop valve for auxiliary fall is added to this. Prevents the content liquid from flowing out while avoiding spontaneous pressurization due to mutual contact with the non-cut valve opening without crimping to the valve opening. In addition to being able to delay the outflow of the content liquid with the water shutoff valve, it is sufficient to compensate for the fact that the bypass ventilation part formed by the cut in the water shutoff valve at the time of the fall becomes a slight outflow part of the content liquid. Therefore, it is possible to secure the safety against the leakage of the content liquid to the outside, and it is possible to secure safety when the body falls. It is possible to ensure the sex.

Further, if a liquid pool having a widened passage is formed between the water stop valve at the time of tipping of the steam passage and the water stop valve at the time of auxiliary tipping, the content liquid flows out beyond the portion of the water stop valve at the time of tipping. However, since the outflow of the content liquid to the outside can be further delayed while the content liquid is stored in the liquid pool, the safety against the outflow of the content liquid can be further improved.
