Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric hot water storage container, and more particularly to an electric hot water storage container such as a domestic electric kettle for heating a content liquid to keep it hot or warm.

[0002]

2. Description of the Related Art Even with an electric hot water storage container, if the inner container can be washed as a whole, it is convenient for cleaning and easy to keep clean.

In order to realize this, it is considered that a container provided with a heater is accommodated in such a manner that an inner container can be taken in and out together with a content liquid discharge passage connected to the outside, and heating can be performed by the heater. The applicant has previously proposed this.

Japanese Utility Model Laid-Open No. 2-119119 discloses an example thereof. This is housed in a container with a heater on the inner bottom surface so that an inner container with a content liquid discharge path connected to the outside can be taken in and out, and this is heated by the heater so that the content liquid cannot be boiled or kept warm. I am trying.

The content liquid discharge path rises upward from the bottom of the inner container to form a bent path that bends downward at the same level as the full water position of the inner container, so that the content liquid is discharged outside the container below the full water position. The pouring outlet faces the pouring position, and the portion that projects forward from the shoulder on the outer surface of the vessel is designed to flow directly below the bottom of this forward projecting portion, and the content liquid pouring path has a simple structure. There are good advantages.

[0006]

However, in the structure for pouring out the content liquid as described above, the curved path portion largely protrudes forward at the upper portion of the inner container, which becomes an obstacle when handling the inner container alone. Moreover, when the inner container is put in and taken out of the container body together with the content liquid discharge passage, the fitting margin between the curved road portion and the forward protruding portion of the shoulder portion of the body is deep, and the inner container is poured from the upper end of the curved road portion. Because the shape to the exit slopes forward,
When the inner container is taken in and out, the outlet side of the curved path is easily caught by the forward protrusion of the shoulder of the body, and the inner container is not easily taken in and out. The front protruding part of is easily damaged.
Further, since the bending path is bent at the same level as the full water position, there is a problem that the content liquid spontaneously flows out beyond the bent portion when the content liquid is slightly above the full water position.

[0007] The above-mentioned Japanese Laid-Open Patent Publication and Japanese Utility Model Laid-Open No. 4-108036, which is different from the above-mentioned Japanese Laid-Open Publication, can solve this problem. Disclosed is one that is connected to an outflow port provided at the bottom of the inner container when the content liquid is attached and detached. This is a valve that prevents inadvertent outflow of the content liquid when the inner container is taken out to the outlet of the inner container and handled alone, and a mechanism that opens and closes this valve in conjunction with the insertion and removal of the inner container, and the content liquid. Since a seal structure or the like for preventing liquid leakage at the connecting portion between the pouring path and the outlet of the inner container is required, the structure is complicated and the cost is high. In addition, it is inconvenient to handle the removed inner container independently and to pour out the content liquid.

Further, even when the bent portion of the bent path is located above the full-filled position and the content liquid is slightly more than full-filled, spontaneous drainage can be prevented, but the inner container is placed in the body. When the tap water is directly added or the lid is closed suddenly, the content liquid in a full state is pushed into the content liquid outlet by receiving tap pressure or lid closing pressure, and is poured from the pouring outlet. Although it is sometimes discharged, since the spout of all of the above is located below the full water position, once such an extrusion outflow occurs, the siphon action will work and the content liquid will flow out of the spout. It is naturally drained until it falls below,
It causes confusion in use due to inadvertent leakage of the content liquid,
There is the inconvenience of getting wet around.

SUMMARY OF THE INVENTION The present invention has an object to solve the above problems, and has a simple structure in which an inner content liquid pouring path is adopted in the inner container, and the pouring portion interferes with the independent handling of the inner container. It is an object of the present invention to provide an electric hot water storage container that can be easily put into and taken out of a container and does not get caught, and does not cause natural outflow even if the content liquid is pushed out by tap water pressure or lid closing pressure. It is a thing.

[0010]

In order to achieve the above-mentioned object, the present invention has a container provided with a heater and a content liquid discharge passage connected to the outside, and together with the content liquid discharge passage. An inner container that is stored so that it can be taken in and out of the container, and the content liquid pouring path rises upward from the bottom of the inner container and forms a bent path that bends downward at a position above the full-filled position of the inner container. The pouring outlet is exposed to the position above the full body where the content liquid is poured out, and the portion projecting forward from the shoulder on the outer surface of the body receives the content liquid discharged from the pouring port and forward. It is characterized in that a discharge passage for guiding and discharging obliquely downward is provided.

[0011]

According to the above-mentioned structure of the present invention, the inner container together with the content liquid discharge passage connected to the outer periphery of the inner container,
Since it is housed so that it can be taken in and out of the container, and is heated by the heater provided in the container, it is possible to heat the liquid content contained in the inner container in the container to perform boiling or heat retention. By opening the lid, the inner container together with the content liquid discharge passage can be pulled out from the body having the heater and handled independently. In addition, the content liquid discharge path forms a bent path that bends downward at a position higher than the full-filled position of the inner container, and pours the content liquid to the position where the content liquid is discharged to the outside of the body without difficulty over the shoulder of the body. Since the outlet faces, it is possible to pour out the content liquid outside the container with the simple and inexpensive passage structure directly attached to the inner container, and the bent path of the content liquid ejection path is more than the position where the inner container is full of water. Also, since it bends downward at the upper position to allow the above-mentioned content liquid to be poured out, even if the content liquid is filled to the full-filled position, it overflows from the bent path of the content liquid pouring path and spontaneously flows out. It is possible to prevent this.

In particular, the spout is located above the full water position so as to spout the content liquid, and the content liquid spouting path along with the inner container is located in front of the shoulder of the container. Since it is possible to eliminate or minimize the fitting margin with the protruding part of the container, even if the spout part is inclined forward, it is a container when the content liquid pouring path is taken in and out with the inner container. It does not get caught on the front of the shoulder of the body or is difficult to get caught, making it easy to put in and take out the inner container. It is possible to prevent the damaged portion from being damaged. Moreover, since the spout is higher than the full water position, when the tap water is directly added or the lid is closed suddenly when the inner container is inside the container, Even if the contents liquid is pushed out to the contents liquid outlet by tap water pressure or lid closing pressure and is poured out from the pouring outlet, there is no inconvenience that the siphon action does not work and the contents liquid is naturally discharged. Since the part on the outlet side of the bend is shortened and it is not bulky,
There is also an advantage that it is not an obstacle to take out and handle the inner container independently.

Further, even if the spout is located above the full water position and there is no fitting margin with the portion projecting forward from the shoulder of the container, or even if it is small, the discharge provided in this projecting portion Since the passage simply receives the content liquid poured out of the container from the outlet of the content liquid outlet and guides it obliquely forward and downward to discharge the content liquid at a position sufficiently distant from the body of the container. Can be guided and discharged.

The body 1 of the inner container 31 through the opened spout 201.
When the inner container 31 is inserted into and removed from the beak-shaped protrusion 4a with a slight fitting margin, the spout 33b has the beak-shaped protrusion 4 when the inner container 31 is fitted in the container 1.
The content liquid can be substantially discharged to the outside of the body 1 by facing the inside of a.

A discharge passage 202 is provided in the beak-shaped protrusion 4a, and the content liquid poured out from the pouring port 33b, which is above the full position of the bent path 33a of the content liquid pouring path 33, is once released to the atmosphere. It is adapted to be received later and guided obliquely downward to the front so that the content liquid can be gently discharged without splash through the opening 203 at the bottom of the beak-shaped protrusion 4a.

Particularly in the structure of the content liquid pouring path 33 as in this embodiment, the content liquid pouring path 33 forms a bent path 33a which is bent downward at a position higher than the full-filled position of the inner container 31. Since the shoulder 33 formed by the shoulder member 4 crosses outward without difficulty and the spout 33b faces the position where the content liquid is spouted outside the vessel body 1, the simple and inexpensive passage structure directly attached to the inner container 31 remains. The content liquid can be poured out of the body 1 by the above, and the bent path 33a of the content liquid pouring path 33 is bent downward at a position higher than the full-filled position of the inner container 31 to pour out the content liquid. Therefore, even if the content liquid is filled up to the full-water position, it is possible to prevent the content liquid from overflowing from the bent path 33a of the content liquid pouring path 33 and spontaneously flowing out.

Further, the spout 33b is located above the full water position so as to spout the content liquid, and the content liquid spouting path 33 of the container 1 when it is taken in and out of the container 1 together with the inner container 31. Since the fitting margin with the beak-shaped protruding portion 4a protruding forward of the shoulder portion is made extremely small as described above, and can be eliminated by the design of the shoulder portion structure by the shoulder member 4 if necessary, Even if the spout 33b is inclined forward, does it not get caught between the inner container 31 and the beak-like protrusion 4a of the shoulder of the body 1 when the content liquid spouting path 33 is taken in and out, Hard to get caught, the inner container 31
The work of taking in and out of the container can be facilitated, and it is possible to prevent the contents liquid pouring path 33 and the beak-shaped protruding portion 4a of the vessel 1 from being damaged by the catch. Moreover, spout 3
Since 3b is higher than the full water position, tap water may be directly added while the inner container 31 is put in the container 1,
Even if the lid is closed suddenly, even if the content liquid in a full state is pushed out to the content liquid discharge passage 33 by tap water or lid closing pressure and is discharged from the outlet 33b, the siphon action Does not work and the content liquid does not spontaneously flow out, and since the portion of the bent path 33a on the spout 33b side becomes short and does not become bulky, it is difficult to take out and handle the inner container 31 independently. There are also advantages.

Further, since the spout 33b is located above the full water position and there is no fitting margin with the beak-shaped protruding portion 4a of the body 1, or even if it is small, the discharge passage provided in this protruding portion. 202 denotes a pouring port 33 of the content liquid pouring path 33.
Since the content liquid poured from b to the outside of the container 1 is simply received and guided obliquely forward and downward, the content liquid can be guided and discharged to a position sufficiently distant from the body of the container 1. ,
The mouth is smaller than the circumference of the body like a teapot, and it can be convenient for injecting liquid into a mouth which is difficult to approach the container 1.

Moreover, in order to properly connect and disconnect the passages associated with the opening and closing of the vessel lid 6, the passages can be aligned with each other and the seal structure capable of separating and contacting each other. Eliminates the need for the seal structure and eliminates the inconvenience of frequently replacing the seal structure due to fatigue over time.

The lower part is attached using the connecting part structure between the inner member 3 and the inner container 31, and the upper part is held by being fitted into the beak-shaped protrusion 32 a of the shoulder member 32 from below, and the contents are together with the beak-shaped protrusion 32 a of the shoulder member 32. It covers the outside of the liquid injection path 33. This makes it possible to prevent the content liquid pouring path 33 from coming into contact with another object or catching and receiving an external force when the inner container 31 is taken out from the body and handled independently.

Further, since the bent path 33a is bent downward at a position higher than the full-fill position A of the inner container 31 to allow the above-mentioned content liquid to be poured out, the full-position position A is filled with the content liquid. Even if this is done, this is the bent path 33a of the content liquid pouring path 33.
It is possible to prevent the water from overflowing and flowing out naturally.

A transparent tube 340 is provided below the content liquid pouring path 33.
The connection is made by connecting a metal connection pipe 603 fitted to a connection port 602 formed in the body of the inner container 31 through a resin elbow 604 made of silicone rubber or the like, so that the lower part of the protective cover 38 is transparent.

In the present embodiment, the cutouts 614 are formed at several positions on the opening edge of the opening 105 which is 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 stop valve 106 at the time of falling is partially fitted into the opening 105 by the inertia of self-confidence 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.

Note that, in FIG. 6, the flow of compressed air at the time of air supply is shown by a solid line arrow, and the flow of steam at the time of vapor discharge is shown by a 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. A return port 616 is provided to return the content liquid that has flowed out or condensed into the vapor passage 87 when the container cover 6 is opened into the inner container 31. The return port 616 includes a container body. While the lid 6 is closed, it contacts the inner peripheral surface of the shoulder member 32 of the inner container 31 and returns to the return port 61.
A seal packing 617 for closing 6 is attached.

Further, 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, which prevents the pressing plate 102 from being pushed down by the rotating position and releases this 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 comes into 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. 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 attached to 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.

FIG. 7 shows a second embodiment of the present invention, and the attachment structure of the connecting pipe 603 of the content liquid pouring path 33 is different from that of the first embodiment.

In this embodiment, an integrally molded flange 603a is provided at the inner end of the connecting pipe 603, and the connecting port 602 in which the seal packing 606 of the inner container 31 is fitted is provided with the flange 603a. With the washer 631 fitted to the outer periphery of the protruding portion of the connecting pipe 603 to the outside of the inner container 31, and the washer 631 having a retaining spring piece 631a on the inner periphery is fitted from the outer end of the connecting pipe 603 to the washer 631 and the flange 603a. The seal packing 606 is sandwiched between and.

This pinching force can be firmly held by the retaining function that the retaining spring piece 631a bites into the outer periphery of the connecting pipe 603 by the movement in the detaching direction and prevents further movement in the detaching direction. The assembling work can be simplified.

FIG. 8 shows a third embodiment of the present invention in which a mica heater is used as the heat retaining heater 8b and the water heater 8 is used.
Only a is embedded in the hot platen 8 as a sheath heater.

The sheathed heater has a water heating condition and state,
That is, since the heater is placed in the high temperature region for a relatively long time, the heat insulation heater having a small capacity lacks durability. This can be avoided by using the mica heater.

Since the heat retaining heater 8b, which is a mica heater, is pushed up by the protruding portion 12d of the heat shield plate 12 and pressed against the back surface of the heating plate 8, there is an advantage that the heater and the mounting structure are simple.

The mica heater is one in which a heater wire having a thickness corresponding to the capacity is wound around a mica plate and is sandwiched between the mica plates, or the mica plate is housed in a heater case. And has excellent durability.

As a specific method of use, when boiling water,
It is preferable to energize both heaters 8a and 8b, and to keep the heaters 8b after boiling to remove chlorine compounds and the like, and to energize only the heat retaining heater 8b and turn on and off the heat retaining heater 8b during heat retention. is there.

In the content liquid pouring path 33 in the present embodiment, the inner end of the connecting pipe 603 and the edge of the connecting port 602 are formed as edge winding portions 632, so that the connecting pipe 603 is connected to the inner container 31.
It is attached to the connection port 602 of.

The circuit housing box 40 is a separate member from the bottom ring 7, and they are connected by screws 633.

FIG. 9 shows a fourth embodiment of the present invention in which the heating plate 8 is formed in an umbrella shape, and the bottom wall of the inner container 31 is also shaped to correspond to this.

As a result, when the inner container 31 is accommodated in the container 1 and placed on the heating plate 8, the mounting position of the inner container 31 is guided by an umbrella-shaped fit with the upper surface of the heating plate 8. Therefore, there is an advantage that the positioning can be performed.

Further, since the contact area between the heating plate 8 and the inner container 31 is increased as compared with the case where the heating plate 8 is in a flat contact, the thermal deformation of the heating plate 8 can be suppressed well and the contact with the inner container 31 can be kept well. The heating efficiency can be improved even in a system in which the inner container 31 is attached to and detached from the heating plate 8 and then heated.

Further, when the same liquid level is set as the empty cooking prevention liquid level, the content liquid remains only in the peripheral portion of the inner container 31, and the safety of the empty cooking can be achieved with a very small remaining amount.

In this embodiment, both the water heater 8a and the heat-retaining heater 8b are mica heaters, both heater wires are wound around a common mica plate, and the mica plate is sandwiched between them to be housed in a donut-shaped case. .

FIG. 10 shows a fifth embodiment of the present invention, in which a plurality of concentric circular projections 8e having a trapezoidal cross section are formed on the upper surface of the heating plate 8 and the bottom wall of the inner container 31 is also formed in this. It has a corresponding shape.

In this embodiment, the same operational effect as the fourth embodiment can be exhibited.

The heaters 8a and 8b are mica heaters,
The hot platen 8 is received on the inwardly bent edge at the lower end of the interior case 2, and is fixed by screws 635 together with the heat shield plate 12 that is applied under the bent edge.

In each of the above-described embodiments of the present invention, the purifier 623 is mounted and held on the inner surface of the inner container 31, but the present invention is not limited to this, and may be stored in the inner container 31. It can be detachably held and the content liquid can be purified. Further, the purifier 623 may be provided in the content liquid pouring path 33.

[0097]

According to the present invention, the heater which is housed in the container so that the inner container can be put in and taken out of the container together with the content liquid discharge passage connected to the outer periphery of the inner container. Since it is heated by, the content liquid placed in the inner container can be heated in the body to heat or keep it warm, and by opening the lid, the inner container can be removed from the body with a heater along with the content liquid discharge passage. Can be pulled out and handled independently. In addition, the content liquid discharge path forms a bent path that bends downward at a position higher than the full-filled position of the inner container, and pours the content liquid to the position where the content liquid is discharged to the outside of the body without difficulty over the shoulder of the body. Since the outlet faces, it is possible to pour out the content liquid outside the container with the simple and inexpensive passage structure directly attached to the inner container, and the bent path of the content liquid ejection path is more than the position where the inner container is full of water. Also, since it bends downward at the upper position to allow the above-mentioned content liquid to be poured out, even if the content liquid is filled to the full-filled position, it overflows from the bent path of the content liquid pouring path and spontaneously flows out. It is possible to prevent this.

In particular, the spout is located above the full water position so as to spout the content liquid, and the content liquid spouting path is forward of the shoulder portion of the container when it is taken in and out of the container together with the inner container. Since it is possible to eliminate or minimize the fitting margin with the protruding part of the container, even if the spout part is inclined forward, it is a container when the content liquid pouring path is taken in and out with the inner container. It does not get caught on the front of the shoulder of the body or is difficult to get caught, making it easy to put in and take out the inner container. It is possible to prevent the damaged portion from being damaged. Moreover, since the spout is higher than the full water position, when the tap water is directly added or the lid is closed suddenly when the inner container is inside the container, Even if the contents liquid is pushed out to the contents liquid outlet by tap water pressure or lid closing pressure and is poured out from the pouring outlet, there is no inconvenience that the siphon action does not work and the contents liquid is naturally discharged. Since the part on the outlet side of the bend is shortened and it is not bulky,
There is also an advantage that it is not an obstacle to take out and handle the inner container independently.

Further, even if the spout is located above the full water position and there is no fitting margin with the portion projecting forward from the shoulder of the container, or even if it is small, the discharge provided in this projecting portion Since the passage simply receives the content liquid poured out of the container from the outlet of the content liquid outlet and guides it obliquely forward and downward to discharge the content liquid at a position sufficiently distant from the body of the container. Can be guided and discharged.
