Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifying type electric hot water storage container.
The present invention relates to a water purifying type electric hot water storage container which is capable of forcibly purifying water with a very simple structure by utilizing convection.

[0002]

2. Description of the Related Art Conventionally, electric hot water storage containers have been widely provided as household electric pots.

[0003] This product keeps the content liquid in a heat-retaining state, or keeps it in a heat-retaining state after boiling water and stores hot water, so that the content liquid at a temperature necessary for extracting coffee or tea can be supplied at any time.

The content liquid is heated for the purpose of boiling or keeping it warm, and in particular, when heated for boiling water, the content liquid is brought into a boiling state to cause an offensive odor, or calcination or its compound, trihalomethane. Foreign matter is released.

[0005]

However, the foreign matter is not sufficiently diffused or removed only by the heat retention or the heating for boiling water.

Therefore, it has been considered to enhance the effect of removing chlorine by continuing the boiling state for a predetermined period of time or repeating the boiling state appropriately.

However, even if this is the case, the diffused scaly component is difficult to escape to the outside of the body, adheres around the body inside the body, etc., and there is a dislike that the adhered scaly is returned to the content liquid again. Is still insufficient.

On the other hand, Japanese Unexamined Patent Publication No. 63-15519,
Japanese Utility Model Laid-Open No. 62-112537 discloses a method in which a water purifying section containing activated carbon, a ceramic for purification and the like is immersed in an inner solution, and water is purified by contact with the inner solution. However, by simply immersing the water purification unit, even if there is convection due to heating or flow due to pouring in the inner solution, it is more free to bypass the water purification unit in the immersed state, so the inner solution does not flow to the water purification unit. There is a problem that the water purification effect cannot be improved because there is no guarantee that the whole solution will come into contact with the water purification part.

Further, Japanese Utility Model Publication No. 61-75228 discloses that
The water purification unit is installed on the bottom of the inner container of the body so that it can be immersed in the inner solution, and the ultrasonic irradiation unit is installed under the bottom of the inner container to give vibration to the inner solution and Disclosed are those that enhance contact. However, this increases the product cost due to the ultrasonic irradiation structure, and also increases the power consumption and the running cost.

In order to solve the above problems, the present invention reliably and frequently causes the content liquid to pass through the water purification section due to convection due to heating and pouring out flow, which may cause an offensive odor or chyle. The main object of the present invention is to provide a purified water electric hot water storage container capable of sufficiently removing foreign matters and having a simple structure and low product cost and running cost.

[0011]

In order to achieve the above-mentioned object, the present invention has a size and a size that fits inside the inner container of the container with a gap between the inner container and the inner circumference of the body. Place the water purification part with a shape so as to face the bottom of the inner container with a gap, and pour out the inner solution to the outside of the container in the part below the water purification part of the inner container. The main feature is that the base introduction port of the outlet is opened, and it is preferable to provide a large number of upper and lower through holes in the water purification unit.

[0012]

According to the above-mentioned structure which is the main feature of the present invention, when the inner solution is heated from the bottom of the inner container to generate convection, the water purification section is placed with a space between the inner solution and the bottom. The solution in the lower part below goes up to the upper part of the water purifier, and by this rise, the solution in the upper part in the inner container descends from above the water purifier to the lower part of the water purifier. Because of the size and shape along the inner circumference of the inner part with a gap, part of the convective inner solution passes between the inner circumference of the body part of the inner container and the water purification part, but this part has a small passage width. Can also make effective contact with the water purification unit, and most of the inner solution passes through the water purification unit, and even the inner solution that has passed through the gap enters the flow passing through the water purification unit by convection. Special means for contacting the purified water with the inner solution by convection of the solution Without requiring equipment and expense by this, all the solution so as to forcibly pass and contact the water purification unit, it is possible to clean water may relatively long time efficiency.

In addition, in addition to this, when the inner solution is poured out of the body through a pouring path having a base introduction opening at the bottom of the inner container, the lower inner solution below the water purification section in the inner container is consumed first. As much as this consumed amount, the solution in the upper part above the water purification part is effectively contacted with the water purification part through the gap between the inner circumference of the body of the inner container and the water purification part. However, since most of the water flows through the water purification section, a special device for bringing the purified water and the inner solution into contact with each other by the pouring flow of the inner solution and thus the expense due to the same are required. Instead, it is possible to efficiently purify water by forcing the entire internal solution to pass through and contact the water purification section.

As a result of the above, the content liquid is heated by convection,
Also, the pouring flow allows the water to pass through the water purification section reliably and frequently, and foreign substances such as offensive odors and scaly substances can be sufficiently removed, and the structure is simple and the product cost and running cost are low.

Further, the water purifying section can be freely put in and taken out at a predetermined position on the bottom of the inner container by the play caused by the gap between the inner container and the inner circumference of the body of the inner container, which is convenient for use.

In addition to the main features, the structure in which the upper and lower through holes are provided in the water purification section facilitates the passage of the content liquid, guarantees active convection of the content liquid, and passes the content liquid and the water purification section. And the number of contacts can be increased.

Gives the temperature information of the liquid. As a result, the control circuit 22 controls energization of the heater 1 so as to keep the content liquid at a predetermined temperature, and determines whether or not the content liquid is boiling.

A body lid 31 is provided on the upper end of the body 4. The body lid 31 has a hinge pin 33 on a bearing portion 32 provided at a rear portion thereof so as to partially open inside the shoulder member 5.
It is pivotally attached so that it can be opened and closed and removed. The body lid 31 can be attached and detached by opening the body lid 31 so that the hinge pin 33 integrated with the body lid 31 can be inserted and removed from the opening of the bearing portion 32. Therefore, it is possible to prevent the body lid 31 from being unintentionally detached when the body lid 31 is in the closed state.

A lock member 34 is provided at the front end of the body lid 31, and when the body lid 31 is closed, the lock member 34 is elastically engaged with a not-shown locking portion provided in a part of the shoulder member 5 so that the body lid 31 is locked.

By being pushed in the backward direction by, the engagement with the locking portion is released, and the locking of the detachable body lid 31 is released.

An inner lid 36 made of a metal plate is attached to the inside of the back plate 35 of the vessel lid 31 and fixed with screws. A seal packing 38 is attached to the outer periphery of the inner lid 36, and the seal packing 38 is brought into contact with the rear portion of the inner container 2 to close the inner container 2.

A steam passage 39 is provided between the inner lid 36 and the back plate 35 of the body lid 31 to allow the steam generated in the inner container 2 to escape to the outside. The abnormal pressure rise is avoided.

In the middle of the steam passage 39, a water stop valve 41 at the time of falling for preventing the liquid content from flowing out through the steam passage 39 when the container 4 falls, and a liquid content when the container 4 falls when the container 4 falls. Even if an attempt is made to flow out to the outside through the vapor passage 39, there is provided a liquid reservoir 40 that stores this in the middle of the vapor passage 39 and delays the outflow to the outside.

On the upper surface of the beak-shaped protrusion 13 of the shoulder member 5, there is provided an operation panel 44 for operating the electric pouring pump 15 and setting various modes of the electric pot.
Various switches on the operation board 45 provided on the inside of the operation panel 44 are pressed, and various indicators such as LEDs provided on the operation board 45 can be turned on and off externally.

A water shutoff valve 61 at the time of falling is provided immediately below the inverted U-shaped bent portion of the pouring path 12.

Further, a water purifying section 64 is provided on the upper part of the inner surface of the bottom where the base introduction port of the pouring path 12 of the inner container 2 is open so as to cover almost the entire area thereof. The water purification unit 64 has a disk-shaped case in which a water purification material 64a such as activated carbon or ceramic is housed in a porous resin-made case 64b. A detachable handle 6 is provided on the upper surface of the case 64b.
4c is integrally formed, and mounting legs 6 are provided on the lower surface at three outer peripheral portions.
4d is integrally formed. In the figure, the case 64b is shown as a single body, but it is possible to fit the separable upper and lower parts so that they can be separated so that the water purifying material 64a can be replaced when it reaches the end of its life.

A rubber positioning bush 65 is elastically attached to the lower end of the mounting leg 64d. The positioning recess 66 into which the bush 65 is elastically fitted is formed in the outer peripheral portion at three locations on the bottom of the inner container 2 facing this, and the bush 65 is elastically fitted into the positioning recess 66 from above. By fitting, the water purification unit 64 is placed in the bottom portion of the inner container 2 in a positioned state, has a gap 1 between the inner surface of the inner container 2 and the inner surface of the bottom portion of the inner container 2, and has an inner circumference of the body portion of the inner container 2. An annular gap S continuous with the space S1 between
It has a size and shape with 2.

As a result, when the inner solution is heated from the bottom of the inner container 2 to generate convection, the inner portion of the lower portion below the water purifier 64 placed with a space S1 between the inner solution and the bottom of the inner container 2 is generated. The solution rises to the upper portion of the water purifying unit 64, and by this rise, the upper inner solution in the inner container 2 descends from above the water purifying unit 64 to the lower portion of the water purifying unit 64.
Since it has a size and shape along the inner circumference of the body with a gap S2, a part of the convective inner solution passes between the inner circumference of the body of the inner container 2 and the water purification section 64, but the passage width Since this is small, this portion can also make effective contact with the water purifying unit 64, and most of the inner solution passes through the water purifying unit 64, and even the inner solution that has passed through the gap S2 can still convection the water purifying unit 64. As it enters the passing stream, the total internal solution forces the water purification section 64 by convection of the internal solution and thus without the need for special equipment and thus the expense for contacting the purified water with the internal solution. By passing and contacting, water can be purified efficiently for a relatively long time.

Since the convection of the content liquid becomes active when the content liquid is boiled, the forced water purification is strongly performed every time the content liquid is boiled.

When the content liquid in the inner container 2 is poured out through the pouring path 12 having the base introduction port opened at the bottom of the inner container 2, the lower inner solution below the water purification unit 64 in the inner container 2 comes first. The water purifier 64 is consumed as much as it is consumed.
The upper part of the upper part of the solution is effectively contacted with the water purification part 64 through the gap S2 between the inner circumference of the body part of the inner container 2 and the water purification part 64, and most of the solution is to the bottom of the water purification part 64. Since it flows through the portion 64, the total internal solution does not require the special equipment for bringing the purified water and the internal solution into contact with each other by the pouring flow of the internal solution, and thus in the same manner as in the above case. The water can be efficiently purified by forcibly passing through and contacting the water purification unit 64.

As a result of the above, the content liquid is heated by convection,
Further, the pouring flow allows the water to pass through the water purification unit 64 reliably and frequently, and foreign substances such as offensive odors or scaly substances can be sufficiently removed, and the structure is simple and the product cost and running cost are low.

Further, the water purification section 64 can be freely put in and taken out at a predetermined position on the bottom of the inner container 2 by the play by the gap S2 between the inner container 2 and the inner circumference of the body of the inner container 2, which is convenient for use.

If there is no space S1 between the water purification section 64 and the bottom of the inner container 2, the content liquid cannot be positioned below the water purification section 64,
Even if the content liquid convects, there is no guarantee that it will pass through the water purification unit 64. Further, even when the content liquid in the inner container 2 is poured out, a bypass state occurs in which only the portion of the water purification unit 64 corresponding to the opening of the pouring path 12 passes. However, the interval S
The presence of 2 ensures the passage of the convective content liquid, and ensures that the passage area of the content liquid in the inner container to the water purification unit 64 due to the pouring of the content liquid extends to the entire water purification unit 64. You can

If the interval S1 is too large, the content liquid convects under the water purifying section 64 and becomes difficult to pass through the water purifying section 64. Therefore, it is preferable that the water purifying unit 64 is positioned near the bottom of the inner container 2.

Further, the gap S2 between the water purification unit 64 and the body of the inner container 2 communicates with the space S1 so that the content liquid can be easily routed under the water purification unit 64, and the space below the water purification unit 64 can be improved. It is possible to prevent the content liquid from becoming deficient, and the upward flow of convection due to the heating of the content liquid is active at the center of the bottom of the inner container 2, and in the gap S2, the convection of the content liquid The downward flow and the downward flow due to gravity do not serve as a passage for bypassing the upward flow.

FIG. 2 shows a fourth embodiment of the present invention. This embodiment shows the case of a manual electric pot in which the content liquid can be poured out by pressing the bellows pump 101.

In this embodiment, the water purification section 64 is a ceramic water purification material 64a formed in a disk shape, is a non-casing type, and has a large number of upper and lower through holes 64f. Is fitted in a predetermined position by fitting a central mounting hole 64g to a small diameter portion 81a at the upper end of a mounting pin 81 provided upright in the center of the bottom of the inner container 2.
It is fixed to the mounting position by a nut 82 screwed into the threaded portion 1a.

The water purifying function in the case of this embodiment is that the water purifying section 64 is provided by the large number of through holes 64f of the water purifying section 64.
The movement of the upper and lower contents liquid can be made more active,
While guaranteeing active convection due to heating of the content liquid, while passing through the water purification section 64 to achieve forced water purification similar to the first embodiment, at the same time, the convection content liquid repeatedly goes up and down through the through holes 64f. The forced water purification can be repeatedly received even by contact with the non-casing type water purification unit 64 at this time, which is different from the case of the first embodiment.

Even in the case of the casing type, however, if the casing has a high liquid permeability and the content liquid coming in contact with the outside can be brought into contact with the water purification material 64a inside without difficulty, as described above. Of course, the non-casing type need not be used.

Reference numeral 103 in the drawing denotes a bellows pump 10.

This is a switching valve that switches and closes the air supply passage 105 from the bellows pump 101 into the inner container 2 and the vapor vent passage 39 in conjunction with the pressing operation of 1.

[0045]

According to the main feature of the present invention, when the inner solution is heated from the bottom of the inner container to generate convection, the water purification unit placed with a space between the inner solution and the bottom of the inner container is used. The solution in the lower lower part rises to the upper part of the water purifying section, and by this rise, the solution in the upper part in the inner container descends from above the water purifying section to the lower part of the water purifying section. Since it has a size and shape that has a gap along its circumference, part of the convective inner solution passes between the inner circumference of the body part of the inner container and the water purification part, but this part also has a small passage width. Effective contact with the water purification unit can be achieved, and most of the inner solution passes through the water purification unit, and even the inner solution that has passed through the gap enters the flow passing through the water purification unit by convection, so the inner solution A special machine for contacting purified water with the inner solution by convection of And without requiring expenses by this, all the solution so as to forcibly pass and contact the water purification unit, it is possible to clean water may relatively long time efficiency.

In addition to this, when the inner solution is poured out of the vessel through a pouring path in which the base introduction port is opened at the bottom of the inner container, the lower inner solution below the water purifying part in the inner container is put first. As it is consumed, the solution in the upper part above the water purification part goes to the lower part of the water purification part by this consumed amount, and partly effectively through the gap between the inner circumference of the body of the inner container and the water purification part. Since it flows in contact with the water and most of it flows through the water purification section, special equipment for bringing the water and the inner solution into contact with each other by the pouring flow of the inner solution, and thus the expense due to the same, is required. Instead, it is possible to efficiently purify the water by forcing the whole internal solution to pass through and contact the water purification part.

As a result of the above, the content liquid is heated by convection,
Also, the pouring flow allows the water to pass through the water purification section reliably and frequently, and foreign substances such as offensive odors and scaly substances can be sufficiently removed, and the structure is simple and the product cost and running cost are low.

Further, the water purifying section can be freely put in and taken out at a predetermined position on the bottom of the inner container by the play due to the gap between the water purifying section and the inner circumference of the body of the inner container, which is convenient for use.

In addition to the main features, the water purifying section having a large number of upper and lower through-holes facilitates passage of the content liquid, guarantees active convection of the content liquid, and It is possible to increase the number of times the water purifier passes and contacts.
