Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a water boiler type liquid container which is a pump injection type and in which the liquid in the inner container housed in the outer casing is heated by an electric heater. It is something.

(Prior Art) Many liquid containers such as thermos flasks have been known in the past, in which a rotary table is attached to the bottom of the liquid container body so that the direction of the liquid container body can be changed freely. When the rotary table is applied to a kettle-type liquid container in which the liquid in the inner container is heated by an electric heater, it is necessary to electrically connect the rotary table side to the electric heater.

FIG. 4 shows a known kettle-type liquid container with a rotary table (Japanese Utility Model Publication No. 151433/1983).
In this known example, the liquid container main body 101 is rotatable on a rotary table 106, and the electric heater 107 is installed so as to be wrapped around the lower outer surface of the inner container 105. On the other hand, a plug connection port 108 is formed on the rotary table 106 side, and the tips of the lead wires 111A, 111B connected to the power terminals 110A, 110B of the plug connection port 108 are connected to respective annular contacts provided on the top surface of the rotary table 106. Plate 112A, 1
12B (Rotation center P of the liquid container body on the rotating table
(concentrically installed).
Then, the band-shaped contact plates 122A, 122B attached to the tips of the lead wires 121A, 121B connected to the electric heater 107 side are slidably pressed against the annular contact plates 112A, 112B, respectively, so that the electric heater 107 can be energized.

In addition, the known kettle-type liquid container shown in FIG.
It is a pump injection type, and uses pressurized air from an air pump 121 provided inside the lid 120 to pump the liquid in the inner container 105 into a series of liquid injection passages 122.
It is designed so that it can be poured out through the spout 123 at the tip thereof.

However, in this known kettle-type liquid container,
Power terminals 110A, 110 of plug connection port 108
B and the electric heater 107 are provided with sliding contacts (ring-shaped contact plates 112A, 112B, strip-shaped contact plate 1
22A, 122B), the wiring connection structure for energizing becomes complicated, and also causes problems such as attenuation of the biasing force of the strip contact plates 122A, 122B, wear of each contact plate, and foreign matter clogging between both contact plates. For example, there was a risk that both contacts would have poor contact (current cannot be applied to the electric heater 107).

In addition, in the kettle-type liquid container shown in FIG.
3 is located directly above the plug connection port 108 when pouring liquid. In such a case, the plug (magnetic plug) 109 may get in the way when the liquid receiving container is positioned below the spout (the liquid receiving container cannot be placed down to pour liquid, and the liquid receiving container is (The plug may come off due to collision with the magnetic plug), or liquid may splash onto the plug due to inadvertent overflow during dispensing or dripping due to poor water drainage after dispensing. There was also the problem that there were risks such as

(Purpose of the invention) In view of the problems of the above-mentioned well-known kettle-type liquid containers, the present invention is a kettle-type liquid container that is a pump injection type and is equipped with a rotary table at the bottom of the liquid container body. In addition to simplifying the wiring connection structure for energizing, the electric heater can be reliably energized, and is highly safe and easy to use, especially when equipped with a magnetic plug. This was done with the purpose of making it happen.

(Means for Achieving the Object) The present invention includes an electric heater for heating the liquid in the inner container in the liquid container main body, and a series of liquid pouring passages that use pressurized air to cool the liquid in the inner container. In a kettle-type liquid container that can be poured through the liquid container to the outside from the spout, a rotary table is provided at the bottom of the liquid container body and is rotatable with respect to the liquid container body, and an outer surface of the rotary table is provided. A plug connection port is provided for connecting a magnetic plug to the liquid container body, and a power supply cord to the electric heater is directly connected to the electric heater from the rotary table side through the bottom of the liquid container body. A positioning member is provided between the rotating table and the positioning member for positioning the liquid container main body within a certain range of left-right arc rotation with respect to the rotating table, and the positioning member is configured to prevent the liquid container main body from making left-right arc rotation with respect to the rotating table. In the final positioning posture of each of the left and right positions, the spout is positioned so as to avoid being directly above the plug connection port.

(Function) In the kettle-type liquid container of the present invention, the rotary table can be rotated in an arc within a predetermined angle range with respect to the liquid container body, and the energizing cord is directly connected to the bottom of the liquid container body from the rotary table side. Since it is connected to the heater, poor contact will not occur between the plug connection port and the electric heater. In addition, the liquid container body has a positioning member on the rotary table that limits the range of left and right arc rotation, so even when the energizing cord is connected directly from the plug connection port to the electric heater, The energizing cord will not be excessively twisted. Furthermore, in the present invention, the above positioning member sets the end point of the left and right arc rotation range of the liquid container body at a position where the spout on the liquid container body side avoids being directly above the plug connection port on the rotary table side. Therefore, by rotating the liquid container body in either the left or right direction to the permissible limit prior to pouring, the spout can be automatically positioned away from directly above the plug connection port. I can do it. This means that, prior to the liquid filling operation, the liquid container body is simply rotated to the left and right arc rotation end positions with respect to the rotating table, without paying attention to the horizontal rotational positional relationship between the spout and the plug connection port. By simply moving the spout, the spout can be reliably positioned at a position shifted from right above the plug connection port in the left-right rotation direction.

(Embodiment) An embodiment of the present invention will be explained with reference to FIGS. 1 to 3. FIGS. 1 and 2 show the first embodiment of the present invention.

The liquid can be poured out to the outside through a series of liquid pouring passages 22. In this embodiment, a low spout type liquid container is used in which the spout 23 of the liquid spout passage 22 is opened at the middle level of the liquid container.

The bottom member 4 includes an annular bottom body 12 that abuts against the lower end of the outer case 3, and a disc-shaped bottom lid 13 whose outer peripheral portion can be engaged with the inner peripheral edge of the bottom body 12 from the lower surface side. It is configured. A portion near the inner circumference of the bottom body 12 hangs considerably downward (hanging wall 12a),
A portion of the bottom of the inner container 5 is accommodated within the internal space of the hanging wall 12a. And this bottom member 4 is
The bottom cover 13 is fixed to a support fitting 18 fixed to the bottom surface of the inner container 5 by tightening screws 19 and pressing the bottom body 12 against the lower surface of the outer case 3.

The center part of the bottom lid 13 (the rotating table 6 of the liquid container body 1)
A cord wire insertion hole 14 is provided in the upper rotation center P) through which an energizing cord 10, which will be described later, is inserted.

An electric heater 7 for boiling water is wound around the lower outer part of the inner container 5.

The rotating table 6 is constructed by fixing a shallow container-shaped upper plate 26 to the upper surface side of a shallow-container-shaped lower plate 25 with screws.

In this first embodiment, a part of the lower part of the liquid container main body 1 (a part near the center of the bottom member 4)
is accommodated in a space S formed on the upper surface side of the rotary table 6 (on the upper surface side of the upper plate 26). In this way, the height of the entire liquid container can be reduced by utilizing the idle space.

Moreover, this rotary table 6 has an outer wall 6a (lower plate 2
The upper end of the outer wall 25a) of the bottom member 4 is the outer wall 4 of the bottom member 4.

Even if water flows down along the outer surface of the liquid container body 1, the water will not infiltrate into the rotary table 6.

A circular annular rising wall 29 is formed near the outer periphery of the upper surface of the upper plate 26 of the rotary table 6 . On the other hand, a downwardly opening annular groove 15 is formed on the lower surface of the bottom body 12 of the bottom member 4 to guide the rising wall 29 horizontally. By fitting the rising wall 29, the rotary table 6 and the liquid container main body 1 are prevented from being displaced from each other in the horizontal plane. Also, rotating table 6
An outward locking portion 27 is formed on the side rising wall 29, and an inward locking portion 17 for locking the outward locking portion 27 is formed in the annular groove 15 on the other side of the bottom member 4.
is formed, the outward locking portion 27 of the rising wall 29 is press-fitted onto the upper side of the inward locking portion 17 on the annular groove 15 side, and both locking portions 27, 17 are engaged with each other, Thereby, the rotary table 6 is supported under the bottom member 4 so as to be horizontally rotatable.

On the upper surface of the upper plate 26 of the rotary table 6, a large number of protrusions 28 that abut against the bottom surface of the annular groove 15 of the bottom body 12 are installed in the circumferential direction. This allows for smooth rotation.

Outer wall 6a of rotary table 6 (outer wall 25 of lower plate 25
A plug connection port 8 is integrally molded in a).
Incidentally, by integrally molding the plug connection port 8 on the rotary table 6 in this manner, the number of parts can be reduced. This plug connection port 8 is configured to be magnetically attachable and detachable, and a magnetic adhesive plate 31 is attached to the inner surface of the plug connection port 8.

A removable magnetic plug 9 is connected to the plug connection port 8. In this magnetic removable plug 9, the magnet 30 provided on the front of the plug easily separates from the magnetic adhesive plate 31 when an object strongly collides with the plug 9 or when someone accidentally trips on the power cord. Then, the plug 9 can be removed from the plug connection port 8.

Power terminal 40 provided in plug connection port 8
An energizing cord 10 is wired between A, 40B and the electric heater 7. This energizing cord 10
are one end 11a, 11a of each lead wire 11, 11
is connected to each power terminal 40A, 40B of the plug connection port 8, and the other end 1 of each lead wire 11, 11 is connected to the power terminal 40A, 40B of the plug connection port 8.
1b, 11b side, a hole 36 formed in the side wall portion of the rotary table top plate 26, a cord insertion hole 14 formed in the center of the bottom member bottom cover 13 (which becomes the rotation center P of the liquid container body 1), and an inner container. 5 Bottom support bracket 1
The other ends 11b, 11b of the lead wires are connected directly to the electric heater 7 through holes 38 formed in the lead wires 8, respectively.

Positioning members A and B are provided between the liquid container body 1 and the rotary table 6 to limit the range of horizontal arc rotation of the liquid container body 1 with respect to the rotary table 6. In this embodiment, this positioning member includes the bottom body 12 on the liquid container body 1 side and the upper plate 2 of the rotating table 6.
6 are respectively provided with abutment protrusions A and B that abut against each other when the liquid container main body is rotated, so that the liquid container main body 1 and the rotary table 6 are rotated from 360° as shown in FIG. Slightly small angle range θ (θ=340~
Relative rotation is possible only within 350°).

Further, the positions of the positioning members A and B are set as follows. That is, in FIG. 2, the liquid container main body 1 is rotated clockwise or counterclockwise with respect to the rotary table 6, and the abutting protrusion A on the liquid container main body 1 side is rotated.
When it collides with either the left or right side of the colliding protrusion B on the rotary table 6 side as indicated by the symbol A' or A'',
The spout 23 is finally positioned at a position displaced by a predetermined angle (α or β) in the horizontal rotation direction from the position directly above the plug connection port 8, as indicated by reference numeral 23' or 23''. Therefore, when the liquid container main body 1 is rotated in the clockwise or counterclockwise direction to the limit of the allowable range (until the abutting protrusions A and B abut each other), the spout 2
As shown by reference numeral 23' or 23'', the liquid is displaced from the plug connection port 8 by a predetermined angle (α or β) in the horizontal rotation direction. The liquid receiving container is less likely to collide with the magnetic plug 9 when positioned below the spout 23, and the liquid injection operation can be performed while the liquid receiving container is placed on the floor below the spout 23. During a liquid injection operation, even if the liquid to be poured out accidentally overflows from the liquid receiving container, the overflowing liquid will not directly splash onto the plug connection port 8 or the magnetic plug 9.

In the kettle-type liquid container of the first embodiment, the liquid container main body 1 can be rotated in an arc within a predetermined angle range θ with respect to the rotary table 6, so that the liquid spout 2
When changing the orientation of the liquid container body 1, such as when changing the direction of the liquid container body 1, it is sufficient to simply rotate the liquid container body 1 in an arc to the left or right on the rotary table 6 while keeping the liquid container on the floor. , the liquid container body 1
The rotation operation can be performed easily and easily.
Moreover, since the plug 9 is connected to the plug connection port 8 provided on the rotary table 6 side, the power cord does not move even when the liquid container main body 1 is rotated in an arc on the rotary table 6, so that the power cord does not move. This prevents troubles such as the cord coming into contact with small objects (such as a pot) placed nearby and causing the small objects to fall over, and since the plug 9 is detachable with a magnet, it is possible to prevent the cord from accidentally turning off the power source. Even when hooked onto a cord, the plug 9 easily comes off from the plug connection port 8,
This has the effect of preventing the liquid container from being knocked over.

Moreover, in the kettle-type liquid container of this first embodiment,
Since the energizing cord 10 is led to the electric heater 7 side through the cord insertion hole 14 provided in the rotation center P of the liquid container body 1 in the bottom member 4, the liquid container body 1 rotates in an arc on the rotary table 6. However, the distance from the cord insertion hole 14 to the connection portion of the energizing cord 10 on the electric heater 7 side is always constant. Therefore, unreasonable actions such as pulling force or twisting are not generated on the current-carrying cord 10.
Even when the liquid container main body 1 is rotated in an arc on the rotary table 6, no trouble occurs to the energizing cord 10. Furthermore, by connecting the power supply terminals 40A, 40B of the plug connection port 8 to the electric heater 7 in a non-contact state with one energizing cord 10, the wiring structure is simplified and the reliability of energization is high. Become.

The kettle-type liquid container of the second embodiment shown in FIG. 3 shows a modification of the mounting structure of the rotary table 6. On the other hand, an outward locking portion 47 is formed on the bottom wall 43 of the bottom member 4 and engages with the inward locking portion 57 from below. In addition, the bottom cover 43 of the bottom member 4 is attached to the bottom body 42 with screws 4.
6, 46 to be fixed from below. When assembling the bottom of this liquid container, the inward locking part 57 of the bottom member 6 is engaged with the outward locking part 47 of the bottom cover 43 before the bottom cover 43 is assembled. , In that state, close the bottom cover 43 to the bottom body 42.
By fixing to the bottom surface of with screws 46, 46,
The bottom member 6 is rotatably supported between the lower surface of the bottom main body 42 and the upper surface of the outward locking portion 47 of the bottom cover 43. In this way, the bottom cover 43 and the rotary table 6 can be attached at the same time with a single screw fixing operation. Incidentally, reference numeral 55 is a lid member for closing the bottom opening of the rotary table 6, and this lid plate 55 is attached after the rotary table 6 is assembled to the bottom of the liquid container body 1. Further, in this second embodiment, the energizing cord 10
is inserted into the mouth edge of the cord insertion hole 14 formed in the center part of the bottom cover 43 (rotation center P of the liquid container body 1) through a gasket 50, so that water flows from the bottom side of the liquid container body 1. This is to prevent the cord from penetrating into the liquid container main body 1 through the cord insertion hole 14.

(Effect of the invention) The kettle-type liquid container of the invention has a power supply cord of 1
0 is directly connected to the electric heater 7 from the rotary table 6 side through the bottom of the liquid container main body 1, so that in a kettle-type liquid container equipped with this type of rotary table 6, the electric heater 7 is connected from the rotary table 6 side to the electric heater 7. It is now possible to connect without contact up to
Compared to the known example shown in the figure, the wiring connection structure for energization can be simplified and the electric heater can be energized more reliably.

Further, in the present invention, the liquid container body 1 can be rotated in an arc only within a predetermined angle range θ with respect to the rotary table 6 by the positioning members A and B, so that the rotation operation range of the liquid container body 1 is limited. Even if the connection is made without contact from the rotary table 6 side to the electric heater 7 as described above, the energizing cord 10 will not be twisted excessively when the liquid container body 1 is rotated. Another advantage is that no problems arise in terms of durability.

Furthermore, the positioning members A and B allow the liquid container body 1 to be connected to the plug on the rotary base 6 side in the left and right final positioning postures of the liquid container body 1 with respect to the rotary base 6. Since the liquid container body 1 is located at a position displaced by a predetermined angle in the horizontal rotation direction from the position directly above the opening 8, the liquid container body 1 is simply rotated in an arc to the right or left to the final stage prior to the pouring operation. This eliminates the need for the plug connection port 8 and the magnetic plug 9 connected thereto to get in the way when a liquid receiving container such as a pot is positioned below the spout 23, making it easier to use. Also, in this way, the spout 23
If you perform a liquid injection operation when the liquid is displaced from the plug connection port 8 in the horizontal rotation direction, even if the liquid to be poured out overflows from the liquid receiving container, the liquid may There is also the effect that the network plug 9 is not exposed to electricity, and there is no risk of electric shock or the like caused by it.
