Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pot that discharges liquid within a container using a pump mechanism.

Generally, as this type of pot, a so-called air pot that uses an air pump as the pump mechanism is known.

In such an air pot, as is well known, boiling liquid water is poured into a container made of a double glass bottle to keep it warm, and when necessary, the boiling water is discharged and used by operating an air pump. It looks like this.

By the way, according to such an air pot, the hot water put in the container does not get cold easily because it is kept warm by the container, but the warmth inevitably decreases over time.

Therefore, when high-temperature boiling water is required, such as when drinking coffee or tea, there is an inconvenience in that the hot water stored in the air pot cannot be used directly.

The present invention has been made based on the above circumstances, and its object is to provide a pot for discharging liquid contained in a container using a pump mechanism, by providing a heater in the container. An object of the present invention is to provide a pot that can maintain a heated liquid at a high temperature.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the figure, 1 is a bottomed cylindrical case with an open top.

An inner lid 2 is provided on the upper surface of the case 1 so as to close the upper surface opening.

A water supply port 3 is formed in the inner lid 2, and a stopper 4 is detachably fitted into the water supply port 3 via a packing 5.

A retaining plate 6 is horizontally provided on the inner bottom of the case 1 by a pair of retaining members 7, and the retaining plate 6 has a bottomed cylindrical shape with a smaller diameter than the case 1 and an open top. A metal container 8 is placed with its bottom surface joined together.

A flange 9 is curved at the upper edge of the case 1, and the flange 9 is airtightly fitted into a groove 10 formed around the lower surface of the inner lid 2 via a packing 11, and is pressed by a presser member 11a. Retained.

Further, a heater 12 is attached to the lower outer peripheral surface of the container 8.

This heater 12 includes a heating coil 13 and a heat retention coil 1.
4 are electrically connected in parallel and built-in, and these coils 13 and 14 are switched and controlled by a temperature controller 14a connected to the outer bottom surface of the container 8. There is.

The heater 12 is electrically connected to a magnetic plug receiver 15 provided on the lower circumferential surface of the case 1 via the temperature controller 14a.

A plug 16 is connected to the magnetic plug receiver 15 by magnetic force.

This plug 16 is connected to a power source (not shown) via a cord 17.

Therefore, if your foot accidentally gets caught on this cord 17, the plug 16 will slide into the magnetic plug receiver 15.
Since it can be easily removed from the case, the case 1 will not fall over.

Furthermore, a heat insulating material 18 is filled between the inner circumferential surface of the case 1 and the outer circumferential surface of the container 8.

On the other hand, an outer cover 19 is rotatably connected to the inner cover 2 by a shaft 20.

The outer lid 19 and the inner lid 2 each have a protrusion 19a,
2a is formed.

A hook 20 that engages with a locking part (not shown) protruding from the protrusion 2a of the inner cover 2 is pivotally supported on the protrusion 19a of the outer cover 19, and is biased by a spring 21. The outer cover 19 can be opened by pressing and rotating the outer cover 20 in the direction of the arrow to disengage it from the locking portion.

In addition, a connection port 22 is formed in the inner lid 2, and a conduit 23 whose lower end faces the inner bottom of the container 8 is provided in the connection port 22.
is connected.

This conduit 23 communicates with an outlet path 24 formed on the upper surface of the inner lid 2 via the connection port 22 .

This lead-out path 24 is formed at a position approximately 180 degrees away from the plug receiver 15 in the circumferential direction of the case 1, and its tip is opened downward from the protrusion 2a of the inner lid 2.

Further, a spherical closure member 25 is provided in the lead-out passage 24 so as to be freely removable, and when the case 1 is knocked down, it rolls to the position shown by the chain line in the figure and closes the lead-out passage 24. 8
This is to prevent liquid L such as hot water contained in the container from flowing out.

Further, inside the outer lid 19, there is provided a mounting plate 28 whose lower surface is hermetically joined to a wall portion 26 which is annularly projecting from the upper surface of the stopper 4 via a packing 27.

A bellows 29 constituting a pump mechanism is provided on the upper surface of this mounting plate 28 with its lower end connected.

A first spring 30 is housed inside the bellows 29, and an upper plate 31 is attached to the upper end.

Further, the outer lid 19 is formed with a mounting recess 32 whose top surface is open.

The bottom plate 33 of the mounting recess 32 has a central portion bulged upward, and a housing recess 34 is formed on the lower surface thereof.

Further, in the mounting recess 32, a push body 35 formed in a hat shape is provided.
is provided.

A plurality of control pieces 36 . . . are formed on the peripheral wall of the pushing body 35 .

This control piece 36 is fitted into a through hole 37 bored in the bottom plate 33 of the mounting recess 32, and the pusher 35
Only when the control piece 3 is rotated by a predetermined angle and pressed
6 passes through the through hole 37.

Further, a shaft body 38 is vertically provided on the inner surface of the upper wall of the pusher body 35 .

The lower end of this shaft body 38 is connected to a hole 3 formed in the bottom plate 33.
A contact body 39 protrudes from the bottom plate 3a and is positioned at the lower end thereof in a housing recess 34 formed on the lower surface of the bottom plate 33.
is provided.

A first spring 3 is provided between this contact body 39 and the upper plate 31.
A second spring 40 weaker than 0 is interposed, and the contact body 3
The pushing body 35 is urged upward and in the rotational direction via the pusher 9.

Further, a first through hole 42 to which an annular packing 41 is attached is formed in a portion of the upper plate 31 facing the abutting body 39.

Therefore, the first through hole 42 is normally open, but when the pushing body 35 is pressed down, the first through hole 42 is closed by the contact body 39, and in this state, the bellows 29 is compressed. be done.

On the other hand, a plurality of second through holes 43 are formed in the mounting plate 28, and a third through hole 44 is formed in a portion surrounded by the wall 26 of the plug 4. Therefore, when the bellows 29 is compressed as described above, the air inside the bellows 29 is pressurized and ejected into the container 8 through the second and third through holes 43 and 44, and is accommodated in the container 8. Since the liquid level of the liquid L is pressurized, the liquid L flows through the conduit 23 to the outlet path 24.
flows out from.

Note that 45 in the figure is a handle whose both ends are rotatably connected to the case 1.

According to the above configuration, when the temperature of the liquid L such as water contained in the container 8 is lower than the set temperature of the temperature controller 14a, for example, the temperature that is just right for brewing coffee, tea, etc. The heating coil 13 of the heater 12 is energized by the signal from the temperature controller 14, and the liquid L is heated.

When the liquid temperature rises to the above set temperature, a signal from the temperature controller 14a causes the decoration coil 13 to
When the current is turned off, the heat-retaining coil 14 is energized, and the heat-retaining coil 14 keeps the liquid L warm.

Therefore, the liquid L stored in the container 8 is always kept at a predetermined temperature and never gets cold, so it can be used whenever high-temperature hot water is needed, for example when drinking coffee or tea. be able to.

Moreover, since the container 8 is covered with the heat insulating material 18,
The liquid L inside the container 8 is difficult to cool down.

Therefore, the liquid L heated by the heating coil 13 can be kept warm for quite a long time without any temperature drop using only the heat-retaining coil 14, so the liquid L is rarely reheated by the heating coil 13. I don't have to do it.

Furthermore, since the plug 16 that supplies power to the heater 13 is connected to the magnetic plug receiver 15 by magnetic force, if a foot or the like is accidentally caught on the cord 17 led out from the plug 16, the plug 16 16 can be easily removed from the magnetic plug receiver 15, so there is no danger of the case 1 falling over.

Further, the plug receiver 15 is oriented approximately 180 degrees in the circumferential direction of the case 1 with respect to the lead-out passage 24 formed on the upper surface of the inner lid 2.

Therefore, even if the liquid L is inadvertently discharged from the outlet path 24, there is no risk that the liquid L will enter the plug receiver 15 and cause an electrical leakage accident.

Note that the present invention is not limited to the above-mentioned embodiment; for example, the pump mechanism may be an electric pump instead of the bellows.

Further, the heater may be provided at the inner bottom of the container.

As described above, the present invention heats and keeps the liquid contained in the container heated by a heater consisting of a heating coil and a heat-retaining coil, and also includes a lid provided to close the open top surface of the container. A pump mechanism is built into the body, and by operating the pump mechanism, the liquid is discharged from a conduit held in the lid with one end facing the inner bottom of the container. do.

Therefore, unlike conventional air pots, the liquid contained in the container does not cool down and is always maintained at a predetermined high temperature, so you can drink coffee, tea, etc. that require high-temperature boiling water. This is extremely convenient in such cases.

In addition, a magnetic plug holder is provided at the bottom of the outer peripheral surface of the case at a position approximately 180 degrees in the circumferential direction from the opening from which the liquid inside the container is discharged, and the plug that supplies power to the heater is connected to the plug holder using magnetic force. I tried to connect it with .

Therefore, if someone inadvertently gets their foot caught on the cord led out from the plug, the plug can easily come off from the plug holder, so there is no risk of the case falling over, and liquid may be accidentally discharged. If you do, the liquid will not enter the plug holder and cause an electrical leakage accident.
