Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pot for discharging liquid within a container by means of 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, an air pump is activated to discharge the hot water for use. It's getting old.

By the way, according to these air pots,
The hot water placed in the container does not get cold because it is kept warm by the container, but the temperature inevitably drops as time passes. 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.

Further, the container made of a double glass bottle has its upper part narrowed to a small diameter, and a stopper is removably fitted into this small diameter. Therefore, since the opening at the top of the container is very narrow, it is not only difficult to clean the inside of the container, but also it is difficult to supply water and dispose of residual hot water.

This invention has been made based on the above circumstances, and its purpose is to provide a heater for the container constituting the pot body to maintain the liquid at a high temperature, and to provide a heater for the container constituting the pot body. To provide a pot in which the inside of the pot body can be easily cleaned, water supplied, and residual hot water treated by making the top opening wide.

Hereinafter, one embodiment of the present invention will be described based on the drawings. In the figure, 1 is a cylindrical case with a bottom and an open top. On the upper surface of this case 1, an inner lid 2 is provided at 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 holding plate 6 is horizontally provided on the inner bottom of the case 1 by a pair of holding members 7, and the holding plate 6 has a smaller diameter than the case 1, an open top surface, and a height. A cylindrical metallic container 8 with a bottom and having the same diameter over its entire length is placed with its bottom surfaces joined together. A flange 9 is bent at the upper end edge of the container 8, 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.
It is held at a. Incidentally, the case 1, the inner lid 2, and the container 8 constitute a pot body. Further, a heater 12 is attached to the lower outer peripheral surface of the container 8. This heater 12 has a built-in heating coil 13 and a heat-retaining coil 14 electrically connected in parallel, and these coils 13 and 14 are connected to the outer bottom surface of the container 8. Switching is controlled by a temperature controller 14a. 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 a foot is accidentally caught on this cord 17, the plug 16 will easily come off from the magnetic plug receiver 15, and 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 lid 19 serving as a lid body is rotatably connected to the inner lid 2 by a shaft 20a. The outer cover 19 and the inner cover 2 each have a protruding portion 1.
9a and 2a are formed. A hook 20 that is engaged with a locking portion (not shown) provided in a protruding manner on a protruding portion 2a of the inner lid 2 is attached to the protruding portion 19a of the outer lid 19, and the hook 20 is attached to the spring 2.
The outer cover 19 can be opened by pushing the hook 20 in the direction of the arrow and disengaging it from the locking part. . In addition, a connection port 22 is formed in the inner lid 2, and a lower end of the connection port 22 is connected to the container 8.
A conduit 23 facing the inner bottom is connected.
This conduit 23 communicates with a lead-out portion 24 formed on the upper surface of the inner lid 2 via the connection port 22 . The tip of this lead-out path 24 is connected to the protrusion 2 of the inner lid 2.
It opens downward from a. Further, a spherical closure member 25 is rotatably provided in the outlet passage 24, and when the case 1 is folded down, it rolls to the position shown by the chain line in the figure and closes the outlet part 24. The liquid L such as hot water contained in the body 8 is prevented from flowing out. That is, the conduit 23 and the outlet path 24 form an outflow path through which the liquid L flows out from the container 8 to the outside.

Further, inside the outer lid 19, a packing 2 is attached to a wall portion 26 whose lower surface is annularly protruded from the upper surface of the stopper 4.
A mounting plate 28 is provided, which is airtightly joined to the mounting plate 28 via 7. A bellows 29 constituting a pump mechanism is provided on the upper surface of this device plate 28, with its lower end connected. The bellows 29 houses the first spring 20 therein, and has an upper plate 31 attached to its upper end. Furthermore, on the outer lid 19,
A mounting recess 32 with an open upper surface is formed.
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, the mounting recess 32 is provided with a pusher body 35 shaped like a hat. A plurality of control pieces 36 are formed on the peripheral wall of this pushing body 35. This control piece 36 is connected to the mounting recess 3
The control piece 36 is fitted into a through hole 37 formed in the bottom plate 33 of No. 2, and the control piece 36 passes through the through hole 37 only when the pushing body 35 is rotated by a predetermined angle and pressed. ing. Further, a shaft body 38 is vertically provided on the inner surface of the upper wall of the pusher body 35 . This shaft body 3
The lower end of 8 is a hole 33a bored in the bottom plate 33.
An abutment body 39 is provided at the lower end of the base plate 33 so as to protrude from the base plate 33 and to be positioned within the accommodation recess 34 formed on the lower surface of the bottom plate 33 . A second spring 40, which is weaker than the first spring 30, is interposed between the abutting body 39 and the upper plate 31, and pushes the pushing body 35 upward and in the rotational direction via the abutting body 39. It is energizing. Further, a first annular packing 41 is attached to a portion of the upper plate 31 facing the abutting body 39.
A through hole 42 is formed. 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 abutting body 39, and in this state, the first through hole 42 is opened. Bellows 29 is compressed.

On the other hand, the device plate 28 has a plurality of second through holes 4.
3 is bored therein, and a third through hole 44 is bored in a portion of the stopper 4 surrounded by the wall portion 26.
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 the air inside the bellows 29 is compressed. Since the liquid level of the liquid L contained in the pipe 8 is pressurized, the liquid L flows out from the outlet path 24 via the conduit 23. Note that 45 in the figure is a handle whose both ends are rotatably connected to the case 1.

According to the above configuration, the temperature of the liquid L such as water contained in the container 8 is controlled by the temperature controller 14a.
When the set temperature of the liquid L is lower than the temperature that is just right for brewing coffee, tea, etc., the heating coil 13 of the heater 12 is energized by a signal from the temperature controller 14, and the liquid L heat up. When the liquid temperature rises to the set temperature, the heating coil 13 is de-energized and the heat-retaining coil 14 is energized by a signal from the temperature controller 14a. The liquid L is kept warm. Therefore, the liquid L stored in the container 8 is always kept at a predetermined temperature and never cools down, so it can be used whenever high-temperature hot water is needed, such as when drinking coffee or tea. can do.

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 that the liquid L can be reheated by the heating coil 13. There is almost no need to do it.

In addition, since the container 8 constituting the pot body is formed to have the same diameter over its entire length in the height direction,
This upper surface opening can be made wide. Therefore, by increasing the diameter of the water supply port 3 of the inner lid 2 provided at the top opening of the container 8, it is possible to facilitate cleaning, supplying water, and disposing of remaining hot water inside the container 8.

Note that this invention is not limited to the above embodiment,
For example, the pump mechanism may be an electric pump instead of a bellows. Further, the heater may be provided at the inner bottom of the container.

As described above, in the present invention, since the heater is provided at the lower part of the container constituting the pot body, the liquid contained therein can be constantly heated and kept at a predetermined high temperature. Further, since the upper opening of the accommodating body of the pot body is formed wide, it is possible to easily clean the inside of the pot body, supply water, and dispose of residual hot water. In addition, since the pot main body side is provided with an outflow path that allows the liquid to flow out of the pot body, when injecting liquid into the container of the pot main body, the outflow path hits the inner surface of the container. It does not cause damage to the water or the outflow channel.
