DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In a conventional pot, since tap water is boiled, dissolved oxygen in the water escapes,
Simply cooling the water that has been boiled in the pot turns it into so-called chilled water, which results in poorly fresh water. The amount of dissolved oxygen in water decreased when the water temperature was high, and the amount of dissolved oxygen in water decreased by boiling water, and the dissolved oxygen escaped from the water.

In order to make fresh and delicious water,
It is necessary to recover the amount of dissolved oxygen in water, but in order to do so, it is necessary to (1) lower the water temperature, (2) increase the contact area and contact time between water and air, and take in oxygen into the water. .

However, even if the boiled water is rapidly cooled, the contact time between the water and the air is too short, and the water becomes bad with no freshness. Also, even if you put the boiled water in a container such as a water bottle and cool it in the refrigerator, it takes time until the water temperature drops,
Further, since the contact area between water and air is small, it takes a long time to recover the dissolved oxygen, which is very inconvenient.

[0006] The present invention is to solve the above problems, and a first object thereof is to provide safe and delicious water in a short time and easily.

The second purpose is to recover the dissolved oxygen amount in a shorter time in addition to the first purpose.

A third object is to surely remove unnecessary components in tap water in addition to the above first object.

A fourth object is, in addition to the above-mentioned first object, to reliably remove unnecessary components in tap water for a long period of time.

[0010]

And a circulation path for circulating the liquid in the container between the container and the cooling means, and in the step of cooling the liquid by the cooling means, the liquid is sprinkled into the air from a sprinkler provided in the circulation path. It is a thing.

A second aspect of the present invention for achieving the second object.
The outlet of the circulation path in the problem solving means is connected to the inside of the container, and the outlet is provided with a flow changing member for changing the flow direction of the liquid flowing into the container to the upward direction.

A third aspect of the present invention for achieving the third object.
The means for solving the problem is configured so that activated water is stored in the water sprinkling portion of the first problem solving means to form a purifying unit, and the purifying unit sprinkles liquid into the air.

A fourth aspect of the present invention for achieving the fourth objective.
The means for solving the problem is provided with a sprinkler plate on the upstream side of the activated carbon, which disperses the flow path of the liquid flowing into the activated carbon in the purification section in the third problem solving means.

[0014]

According to the first problem solving means, the liquid such as water contained in the container is heated and boiled by the heating means to sterilize the water by boiling, and the calcination contained in the water, Defective components such as musty odor and trihalomethane are removed, and then cooled by cooling means. In this cooling step, the boiled liquid in the container is sent to the cooling means through the circulation path to cool the liquid.However, since the sprinkler is provided in the circulation path, the liquid flowing through the circulation path is in the air. Water is sprayed and the liquid effectively takes in oxygen. The function of the water sprinkler increases the surface area and contact time of the liquid in contact with air, and recovers dissolved oxygen in water in a short time. Moreover, since the liquid is cooled and the dissolved oxygen is recovered at the same time, delicious water can be produced in a short time.

According to the second problem solving means, the flow of the liquid circulating in the circulation path in the cooling step is changed upward by the flow changing member at the outlet of the circulation path, so that the time during which the liquid comes into contact with the air is lengthened. are doing.

By turning the external operation knob 11, the switch 10 is actuated, the rotation speed of the first pump is controlled, and the amount of the liquid discharged from the discharge pump 4 to the discharge port 9 can be adjusted. An external operation knob 11 or the like constitutes a derivation operation unit 12 that controls the amount of liquid that is derivable from the container 2.

Further, the upper portion of the outlet path 8 is branched into a outlet pipe 13 communicating with the outlet 9 side and a return pipe 14 communicating with the upper portion inside the container 2, and the outlet side switching valve 15 is provided at this branch point. And the liquid from the outlet path 8 is connected to the outlet 9
It is configured to selectively switch between the side and the inside of the container 2 to flow.

An electric pump (hereinafter referred to as a circulation pump) 16 for circulating the liquid in the container 2 is arranged at the bottom of the container 2, and the circulation pump 16 is driven by a second motor 17. The suction port 18 of the circulation pump 16 communicates with the bottom of the container 2, and the discharge port 19 of the circulation pump 16 has the suction port 18 of the first water channel 2.
It communicates with the circulation side switching valve 21 via 0.

The circulation side switching valve 21 is branched into a second water passage (heating side circulation passage) 22 and a third water passage (cooling side circulation passage) 23, and the respective water passages 22 and 23 are located above the container 2. And is poured into the water purification unit 24 attached to the upper portion of the container 2.

An electric heater 26 is wound around the outer wall of the heating container 25 disposed in the middle of the second water passage 22 to heat the liquid passing through the heating container 25. The heater 26 and the heating container 25 are used to heat the liquid 2
7 (hereinafter referred to as a boiler) is configured.

A cooling means for cooling the liquid is arranged in the middle of the third water passage 23, and this cooling means is specifically constituted by a heat exchanger 28. The heat exchanger 28 is the water container 2
9, the thermoelectric element 30 by the Peltier effect, the heat dissipation member 31 and the like, the thermoelectric element 30 is the water absorption container 2 on the heat absorption side.
The heat radiating side is attached to the heat radiating member 31 with pressure contact. The heat dissipating member 26 attached to the thermoelectric element 30 is cooled by a blower 32 arranged below the heat dissipating member 26. The blower 32 applies the outside air introduced from the outside of the main body 1 into the main body 1 to the heat dissipating member 26 so that Is taken out and exhausted to the outside of the main body 1 again.

A water purification agent 33 such as activated carbon and a mineral additive containing calcium carbonate and magnesium carbonate as main components are contained in the purification section 24 arranged in the container 2, and the heated liquid flows out. The water purifying agent 33 is located below the outlet of the second water passage 22, and the outlet of the third water passage 23 through which the cooled liquid flows out is arranged in parallel with the outlet of the second water passage 22 in the horizontal direction. Are not shown in the drawings. The mineral additive is located in the water purification section 24 below the outlet of the third water channel 23, and the heated liquid is the water purification agent 3
The liquid purified by No. 3 and cooled and having a lowered temperature passes through the mineral additive, and the mineral is dissolved in the passed liquid. In particular, since minerals do not easily flow into the liquid when the liquid temperature is high, the minerals are arranged at the outlet through which the cooled liquid flows out so that the minerals can be efficiently dissolved in the liquid.

The liquid in the container 2 is heated by circulating it through the second water channel 22, and is cooled by circulating the third water channel 23, so that the liquid in the container 2 is heated or cooled. However, a temperature sensor 35 for detecting the temperature of the liquid in the container 2 is attached to the outer bottom surface of the container 2 so that the liquid in the container 2 can be heated / cooled to a predetermined temperature by heating or cooling. A container side heat insulating material 34 made of hard urethane foam is attached to the outer wall of the container 2 to prevent dew condensation on the outer wall of the container 2.

Further, a pump side heat insulating material 36 made of hard foam urethane is attached so as to cover the lead-out pump 4 and the circulation pump 16 arranged on the bottom side of the container 2, and dew condensation occurs on the outer wall of each pump 4, 16. Is being prevented. The inside of the lid 3 is also filled with the lid-side heat insulating material 37 made of hard foamed urethane, to prevent dew condensation on the outer wall of the lid 3. Further, since the cold liquid flows in the third water passage 23 on the cooling side, the outer wall of the third water passage 23 easily condenses, but the third water passage 23 is embedded together in the container side heat insulating material 34 that covers the outer wall of the container 2. Therefore, the occurrence of dew condensation can be suppressed as much as possible.

Next, the operation of the pot having the above structure will be briefly described. First, when the liquid in the container 2 is once boiled to remove unnecessary components such as scaly contained in the liquid,
The circulation side switching valve 21 is switched to the second water channel 22 side,
While operating the circulation pump 16 and energizing the heater 26, the liquid in the container 2 is heated by the boiler 25 while
The water channel 22 and the container 2 are circulated (heating step). That is, the liquid in the container 2 is sucked through the suction port 18 of the circulation pump 16 and is pressure-fed through the discharge port 19 so that the first water passage 2
0, and then flow back into the container 2 via the second water passage 22. At this time, the liquid is heated by the heater 20 when passing through the heating container 21, and by continuing this operation, the temperature of the liquid in the container 2 rises and reaches boiling. Further, at this time, since the liquid passes through the water purification agent 33, calcination, musty odor,
Remove unnecessary components such as trihalomethane.

To cool the boiled liquid to the cold storage temperature (cooling process), the circulation side switching valve 21 is set to the third water passage 23.
Then, the circulation pump 16 is operated, the thermoelectric element 25 is energized, and the blower 27 is operated. That is,
When the thermoelectric element 25 is energized, the temperature of the heat absorbing side pressed against the water container 24 is lowered by the Peltier effect, and the water container 24
The heat of the liquid passing through the inside is taken, guided to the heat radiating member 26 that is in pressure contact with the heat radiating side, and the heat is forcibly discharged to the outside of the main body 1 by the blower 27. Continue this operation,
By cooling the liquid passing through the heat exchanger 28 arranged in the middle of the water passage 23 and causing the liquid to flow back into the container 2, the liquid is quickly cooled to the set temperature. The above cooling operation is continued until the temperature detected by the temperature sensor 30 reaches the set cool temperature (for example, 10 ° C. or 16 ° C. at which deliciousness is felt).

Further, the operation on the deriving side will be briefly described.
When heating the liquid in the container 2, the outlet side switching valve 15
Is switched to the side of the reflux pipe 14 to operate the lead-out pump 4 in a state where the path between the bottom and the upper part of the container 2 is in communication, that is, in the state where the circulation path is formed, the liquid in the lead-out path 8 is It is possible to remove unnecessary components in the liquid that have not been heated in the outlet passage 8 by circulating in a circulating manner.

When the liquid in the container 2 is discharged from the discharge port 9 by the external operation knob 11, the discharge side switching valve 15 is switched to the reflux pipe side as described above before the discharge.
When the lead-out pump 4 is operated, the liquid in the lead-out path 8 is circulated and replaced, and the temperature of the liquid in the lead-out path 8 is changed to the container 2
The temperature inside is almost equal. After this circulation operation is completed, the outlet side switching valve 15 is switched to the outlet pipe 13 side, and the liquid is led out from the outlet port 9. By operating the outlet side switching valve 15 as described above, even when a small amount of liquid is discharged, that is, even when the liquid in the discharge path 8 is discharged, the liquid kept at high temperature or the ambient temperature The liquid kept cold at the following low temperature will not be discharged.

Next, the operation of the cold insulation process will be described in more detail. As described above, in the cold insulation process, the boiled liquid in the container 2 is circulated in the heat exchanger 28 to be cooled, flows out into the container 2 from the outlet of the third water passage 23, and flows into the purification unit 24. . As shown in the figure, the purification unit 24 is installed above the full water level A in the container 2, so the purification unit 24
The liquid flowing from the lower part of the water is sprinkled in the air between the lower surface of the purification unit 24 and the water surface of the liquid, and the oxygen in the air is efficiently dissolved in the liquid, and the amount of dissolved oxygen can be increased in a short time. . In this way, by increasing the surface area of the liquid in contact with the air and the contact time, dissolved oxygen in the liquid is recovered in a short time, and delicious fresh water can be obtained.

In this embodiment, if the distance between the purifying section 24 having the water sprinkling function and the water surface of the liquid in the container 2 is increased, the time during which the liquid comes into contact with the air is increased, so that the recovery of the dissolved oxygen is further improved. It will be a short time.

Further, in the heating step, the boiling liquid is circulated to the purifying section 24 and the water purifying agent 33 such as activated carbon is repeatedly passed therethrough. Therefore, in particular, calcination contained in water is caused by physical adsorption and catalytic reaction of activated carbon. It surely removes bad components such as musty odor and trihalomethane, and makes safe water in a short time. Here, since the purification unit 24 also serves as the water sprinkling unit, the cost can be reduced. Therefore, safe and delicious water can be easily produced in a short time and at low cost.

When water was boiled in the pot of the above-mentioned embodiment and then circulated and cooled, the results shown in the following table were obtained for the recovery time of the amount of dissolved oxygen in water.

[0036]

[Table 1]

Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 7A is a front view of the main part of the inner surface of the container with the purifying portion removed, and FIG. 8B is a sectional view taken along line BB of FIG.

As is apparent from this figure, this embodiment is the third water channel (cooling side circulation path) 2 in the first embodiment.
3 is different in that a flow changing member 39 is attached to the outlet 38 in the container 2 of No. 3. In addition, 40 is an outlet in the container 2 of the second water channel (circulation path on the heating side) 22.

When the liquid from the third water channel 23 advances to the outlet 38, the flow changing member 39 changes the flow of the liquid upward as indicated by arrow C, and the liquid is sprayed into the air. . The liquid sprinkled in the air descends due to gravity, falls into the purifying unit, and further contacts the air from below the purifying unit to the water surface of the liquid in the container 2. As described above, by providing the flow changing member 38, the liquid cooled by the cooling means is brought into contact with air to increase the area and time, and it is possible to efficiently dissolve oxygen in the liquid, and the liquid can be melted in a shorter time. The amount of dissolved oxygen in it can be increased.

Next, a third embodiment of the present invention will be described with reference to FIG. In the present embodiment, by providing the fountain part 41 in the middle of the third water passage (circulation passage on the cooling side) 23 of the first embodiment,
Jetting the cooled liquid into the air at the fountain part 41,
The water is sprinkled and the time of contact with air is extended so that the dissolved oxygen in the liquid can be recovered in a shorter time. If the fountain part 41 comes into contact with the air while the liquid circulates, the same effect can be obtained regardless of where the third water passage 23 is provided.

Next, a fourth embodiment of the present invention will be described with reference to FIG. The difference from the first embodiment is that a water spray plate 42 having holes in a grid pattern is provided above the activated carbon and the mineral additive of the water purification agent 33 in the purification unit 24. The boiling liquid discharged from the second water channel in the heating step is dispersed in the flow channel by the water sprinkling plate 7 and comes into uniform contact with the activated carbon in the purification unit 24, so that the adsorption of the defective component of the liquid is caused by the specific activated carbon. Since it is possible to prevent the purification effect from being reduced by concentrating on, it is possible to extend the life of the activated carbon,
You can make safe water for a long time.

Further, in the cooling step, the liquid flowing out from the third water passage is dispersed in the passage by the water sprinkling plate 7 in the purifying section 24, and the liquid is concentrated and does not pass through the specific portion of the mineral additive to the air. Since water is sprinkled inside, the contact area between water and air increases, dissolved oxygen in water recovers in a shorter time, and delicious water with a refreshing feeling can be created. Minerals can be sufficiently dissolved in the liquid from the additive.
Therefore, safe and delicious water can be easily produced in a short period of time.

Although the sprinkler plate 7 is provided with lattice-shaped holes,
With this shape, the same effect can be obtained in any shape as long as the water is evenly contacted with the activated carbon and the mineral additive. Further, although the liquid in the container 2 was circulated in the heat exchanger 28,
Even if the cooling means is directly attached to the container 2 to remove heat and cool, the same effect can be obtained.

[0044]

As is apparent from the above description of the embodiments, according to the first means for solving the problems of the present invention, the liquid contained in the container is heated by the heating means to bring it to a boil. It is possible to make a safe liquid by performing sterilization by boiling and removing bad components such as chlorine, musty odor and trihalomethane contained in the liquid. Further, in the cooling step by the cooling means, the liquid is circulated through the water sprinkling portion provided in the circulation path and sprinkled in the air. This allows
The surface area and contact time of the liquid in contact with the air increase, and dissolved oxygen in the water recovers in a short time, producing delicious fresh water. In addition, since water is cooled and dissolved oxygen is recovered at the same time, safe and delicious water can be easily produced in a short time.

According to the second means for solving problems, the flow of the liquid circulating in the circulation path in the cooling step is changed upward by the flow changing member at the outlet of the circulation path, and the time during which the liquid comes into contact with the air is lengthened. Therefore, the recovery of the amount of dissolved oxygen in the liquid can be accelerated.

According to the third means for solving the problems of the present invention, since the sprinkling section is provided with the purifying section containing the activated carbon and the hot water is circulated to the purifying section and passed through the activated section in the water heating step, the activated carbon is physically removed. By adsorption and catalytic reaction, bad components such as scaly, musty odor and trihalomethane contained in water can be reliably removed, and safer water can be produced in a short time. Further, since the purifying unit also serves as the water sprinkling unit, the cost can be reduced. Therefore, reliable and delicious water can be easily produced in a short time and at low cost.

According to the fourth means for solving the problems of the present invention, by providing the water sprinkling plate for dispersing the flow paths of water to the activated carbon in the purification section, the hot water in circulation is unevenly distributed on the activated carbon in the purification section in the heating step. Can be contacted without. As a result, adsorption of bad components contained in water is not concentrated on specific activated carbon and it is possible to prevent deterioration of the purification effect, so that the life of activated carbon can be extended and safe water can be obtained for a long time. Can be created. Further, in the cooling process, the circulating water is released into the air without concentrating on a specific part of the activated carbon, so the contact area between the water and the air is increased, and the dissolved oxygen in the water is further reduced in a short time. You can recover delicious water with a refreshing feeling.
