Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a pot for heating and cooling water.

[0002]

2. Description of the Related Art When boiling water, such as sencha or gyokuro, is used after being cooled to a predetermined temperature, or when hot water at a predetermined temperature is urgently needed when adjusting infant powder. Therefore, there is a demand for a pot capable of quickly cooling hot water, which is obtained by boiling water to remove impurities and making it sanitary, to the intended temperature.

Conventionally, this type of pot has a structure shown in FIG. 3, and the structure will be described below. That is, the container 103 for storing the water 102 is arranged in the main body 101. A heater 104 is attached to the bottom of the container 103 to heat the water in the container 103. Further, the suction port side is provided with a discharge pump 105 that communicates with the inside of the bottom of the container 103.
2 is led out to the water outlet 106, the tip side of the water outlet 106 is exposed to the outlet 107 provided in the upper front part of the main body 101, and the water in the container 103 is led out from the outlet 107. The operation knob 108 provided on the upper surface of the main body 101 is operated to operate the discharge pump 105.

Further, the suction port side is provided with a circulation pump 109 which communicates with the inside of the bottom of the container 103, and the discharge port side of the circulation pump 109 has a circulation path 110 which communicates with the upper part of the container 103.
Are connected so that the water in the container 103 passes through the heat exchanger 111 arranged in the middle of the circulation path 110. The heat exchanger 111 is cooled by cooling air from a cooling fan 112 (not shown). In addition, circulation route 1
A water purification section 113 containing a water purification agent such as activated carbon is attached to the outlet of the container 103 on the side of the vessel 103. Also,
At the bottom of the container 103, a temperature sensor 114 for detecting the temperature of water in the container 103 is provided.

In the pot having the above structure, when tap water is put into the container 103 for heating, the heater 104 is energized to heat the water in the container 103 from the bottom. Heater 1
When the temperature sensor 114 detects that the water in the container 103 reaches the boiling temperature by 04, it keeps the boiling state for several minutes to remove unnecessary components (calcium, musty odor, trihalomethane, etc.) contained in tap water to some extent. . After that, the power supply to the heater 114 is stopped and the circulation pump 109 and the cooling fan 112 are operated to remove heat from the water circulating in the heat exchanger 111 to forcibly cool the temperature of the water 102 in the container 103. While performing this cooling operation, the container 1
The water 102 in 03 circulates, and further, unnecessary components (chlorine, musty odor, trihalomethane, etc.) of water circulated in the water purification unit 113 attached to the outlet of the circulation path 110 are removed.
Then, when the temperature sensor 114 detects that the water in the container 103 has dropped to a predetermined temperature, the operations of the circulation pump 109 and the cooling fan 112 are stopped.

[0006]

However, in the conventional pot, the tap water in the container 103 has a function of removing unnecessary components. Therefore, the unnecessary components (calcium, musty odor, trihalomethane, etc.) are removed to some extent, and tap water is removed. It contributed to the removal of substances that deteriorate the bad odor and flavor of, and contributed to the improvement of tap water that could not withstand drinking. However, it wasn't enough to bring out the original taste of water.

Beverages such as coffee, Japanese tea, and black tea are
The original taste of water enhances those tastes, and makes delicious coffee. The reason why mountain water is said to be delicious has not been completely clarified, but it is said that the action of trace components, especially minerals, in the water contributes to the deliciousness of water. Furthermore, it is said that the deliciousness is further enhanced by the water temperature (10 ° C to 15 ° C). The water content, that is, the deliciousness of water at a low temperature greatly reflects the content of mineral components.

However, when the water temperature is raised, the original taste of water cannot be felt, and rather, unnecessary components (calcium, musty odor, trihalomethane, etc.) remaining in a trace amount in water are vaporized. And emits an unpleasant odor. This water temperature, that is, the unpleasant factor of water at high temperature, is a small amount of unnecessary components remaining in the water (chalk, musty odor,
The content of trihalomethane etc.) is largely reflected.

In the conventional pot, unnecessary components (chalk, musty odor, trihalomethane, etc.) can be removed to some extent, but in order to allow water in the container to pass through while cooling, even though it has a purification part for activated carbon. However, it was not possible to completely remove unnecessary components, and it was not possible to adjust the mineral content that contributes to the deliciousness of water. Therefore, in the conventional pot, it was not possible to adjust the water to the original taste and to completely eliminate the discomfort in the high temperature state.

Further, in the conventional pot, when the water in the container is circulating, the water circulated into the container from the circulation path along with the sound of the circulation pump falls from the bottom of the purifying unit onto the water surface in the container. The dripping sound of water was jarring. Especially this sound
After the circulation is completed and the circulation pump is stopped, when the water retained in the activated carbon of the purification unit falls, it causes discomfort to the human ear.

In view of the above-mentioned problems, the present invention realizes the original taste of water. In order to realize the original taste of water, the water after boiling is quickly cooled in a temperature range to bring out the taste of the water, and the mineral components for further bringing out the taste are adjusted. The purpose is to provide a pot that can be used.

Another object of the present invention is to provide a pot for removing unnecessary components more completely than ever before.

Another object of the present invention is to provide a pot in which an unpleasant dropping sound of accumulated water from the purifying unit which occurs when the water in the container is circulating and after the circulation is stopped is provided.

[0014]

[Means for Solving the Problems] A first means for solving the problems of the present invention for achieving the above object is to provide a container for storing water, a lid for covering the upper part of the container so as to be openable and closable, and Heating means for heating the water, a mineral addition section for adding minerals to the water in the container, a cooling means for cooling the water in the container, a path for circulating the water between the heating means and the container, A path for circulating water between the cooling means and the container,
A circulation pump for supplying water in the container to each path is provided, and the mineral addition unit is arranged so as to receive the water discharged from the path on the cooling means side and introduce it into the container, and the water in the container as a heating means. Water is circulated between the cooling means and the container after heating and boiling by circulating the water between the container and the container.

A second means for solving the problem is that the mineral addition section in the above-mentioned first means for solving the problem comprises a water dispersion member, a mineral additive and a deflecting member, and receives water discharged from a passage on the cooling means side. It is arranged so as to be introduced into the container, a water dispersion member is provided above the mineral additive, and a deflecting member is formed below this mineral additive so that the water discharged from the passage on the cooling means side is leveled by the water dispersion member. Direction, the mineral additive is passed through, and the flow of the passed water is deflected by the deflecting member so as to be introduced into the container along the inner wall surface of the container.

A third problem solving means is the above first problem solving means, which is provided with a purifying section for purifying water in the container, and the purifying section is constituted by a water dispersion member, a water purifying agent and a deflecting member. ,
Arranged so as to receive the water discharged from the passage on the heating means side and introduce it into the container, the water dispersion member is provided above the water purification agent, and the deflection member is formed below this water purification agent. Water discharged from the passage is horizontally dispersed by the water dispersion member, passes through the water purification agent, and the flow of the passed water is deflected by the deflecting member so as to be introduced into the container along the inner wall surface of the container. is there.

A fourth problem-solving means forms a water collecting portion by providing a step on the deflecting member in the second or third problem-solving means, and holds a mineral additive or a water purification agent in each path. So as to project from the inner wall surface of the container, the water collecting portion forms an opening in a part of the deflecting member on the inner wall surface side of the container in proximity to the inner wall surface, and from this opening along the inner wall surface of the container. Water is introduced into the container.

The fifth problem solving means is an integration of the water purification section and the mineral addition section in the above-mentioned third and fourth problem solving means.

The sixth means for solving problems is such that the water purification part and the mineral addition part in the means for solving the third and fourth problems are made detachable.

[0020]

According to the first means for solving the problems, the water in the container is first heated and boiled while being circulated between the heating device and the container, whereby unnecessary components in the water (chalk, musty odor, After removing trihalomethane etc. to some extent, the boiling water is circulated between the cooling means and the container to rapidly cool the delicious water to the temperature range. A mineral addition section is provided in this cooling circulation path to pass water through the mineral addition section while cooling and circulating the water, thereby adding a mineral component to the water to produce delicious water at low temperature.
However, it is desirable to adjust the mineral component to a very small amount, and if excess mineral is released into the water, not only will the taste of the water be impaired, but it may also deposit as scale when the temperature of the water becomes low. Also comes out. Therefore, the mineral additive is adjusted to have a proper solubility and at the same time is passed through while being cooled and circulated so as to have a proper content.

According to the second means for solving the problems, the water discharged from the circulation path is received by the water dispersion member and dispersed and dropped in the horizontal direction so that the circulation water is sufficiently diffused and brought into contact with the mineral additive. Furthermore, if water drops from the bottom of the mineral addition part as it is, an unpleasant dripping sound is generated.In order to prevent this, the water that has passed the mineral additive to the bottom of the mineral addition part is guided along the inner wall surface of the container. The deflecting member deflects the flow so that it falls.
As a result, the water does not drop from the bottom of the mineral additive to the surface of the water in the container as it is, but drops along the inner wall surface, so that no dropping noise is generated.

A third problem solving means is the same as the first problem solving means, in which a purifying section is provided in the circulation path on the heating means side,
Purification is performed while boiling water in the container.
As a result, the water passing through the purification unit is in a high temperature state,
When contacting with a cleaning agent such as activated carbon, unnecessary components (calcium,
Since mold odor, trihalomethane, etc. are in a very activated state, unnecessary components (chalk, mold odor, purifier, etc.)
(Trihalomethane, etc.) can be reliably removed, and discomfort does not occur even in hot water.

The fourth problem solving means is a structure for more effectively carrying out the second and third problem solving means. In order to more reliably cause the water passing through the mineral addition section or the purification section to follow the inner wall surface of the container, a deflecting member provided in each is formed with a water collecting section for collecting the passed water and forming a large flow, The water collected in this water collecting part is led out into the container from the opening part of the water collecting part along the inner wall surface of the container. The amount of water discharged from the circulation path is not large enough to create a large flow, depending on the performance of the circulation pump. Moreover, in order to horizontally disperse the water by providing a water dispersion member so as to contact the mineral additive or the purifying agent as much as possible,
If a small amount of water is further dispersed and the water received by the deflecting member is to be guided out along the inner wall of the container as it is, the space between the deflecting member and the inner wall surface of the container must be very narrow. The fine structure that requires such precision causes troubles such as failures and route clogging. Therefore, in order to ensure that water is discharged along the inner wall surface of the container even if the gap provided between the inner wall surface of the container and the deflecting member is slightly large, a part of the deflecting member facing the inner wall surface of the container is provided. A water collecting portion is formed by providing a step, and a portion where the inner wall surface of the container and the water collecting portion face each other is opened.

According to the fifth means for solving problems, the purification section and the mineral addition section of the third or fourth means for solving problems are integrated. This allows the pot to be compact and have high performance.

According to the sixth means for solving problems, in the third or fourth means for solving problems, the purifying section or the mineral adding section is made detachable. As a result, when each part is unnecessary, it can be freely attached and detached, and the convenience of handling is enhanced.

In the figure, reference numeral 1 denotes a main body, and a container 2 having an open top is housed in the main body 1. The top opening of the container 2 is covered with a lid 3 so as to be openable and closable. At the bottom of the container 2, an electric pump (hereinafter referred to as “deriving pump”) 4 for discharging the water in the container 2 (generally, tap water is supplied) to the outside of the container is arranged. It is driven by the first motor 5.

A switch 10 for controlling the operation of the first motor 5 is provided above the outlet 9, and the switch 10 is provided on the front surface of the main body 1 so as to project therefrom.
It is linked to 1. 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 water discharged from the discharge pump 4 to the discharge port 9 can be adjusted. An external operation knob 11 and the like constitute a derivation operation unit 12 that controls the amount of water that is deducted 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. Is arranged, and the water from the outlet path 8 is selectively switched between the outlet 9 side and the inside of the container 2 to flow.

An electric pump (hereinafter referred to as a circulation pump) 16 for circulating the water 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 thereof has a first water passage 20.
Through the switching valve 21 on the circulation side.

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 each water passage 22 and 23 is an upper portion of the container 2. The second water channel 22 is connected to the water purification section 24a attached to the upper portion of the container 2, and the third water channel 23 is also poured to the mineral addition section 24b.

An electric heater 26 is wound around the outer wall of the heating container 25 arranged in the middle of the second water passage 22 to heat the water passing through the heating container 25. The heater 26 and the heating container 25 are used to heat the water 27.
(Hereinafter referred to as a boiler) is configured.

A cooling means for cooling water 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 31 attached to the thermoelectric element 30 is cooled by a blower 32 disposed below the heat dissipating member 31, and 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 31 to dissipate heat from the heat dissipating member 31. 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 34 containing calcium carbonate and magnesium carbonate as main components are housed in the water purification section 24a and the mineral addition section 24b arranged in the container 2, respectively. Yes, there is a water purification unit 2 below the outlet of the second water passage 22 where heated water flows out.
4a (water purification agent 33) is located, and the outlet of the third water channel 23 through which the cooled water flows out is arranged in parallel with the outlet of the second water channel 22 in the horizontal direction, and this outlet is not shown in the drawing. A mineral additive 34 is located in the mineral addition part 24b below the outlet of the third water passage 23. The heated water is purified by the purifying agent 33, and the water whose temperature has been lowered by cooling is mineral. The mineral is dissolved in the water that has passed through the additive 34. In particular, since it is difficult for minerals to flow out into the water when the water temperature is high, the minerals are arranged at the outlet where the cooled water flows out so that the minerals can be efficiently dissolved out into the water.

The water 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 water in the container 2 is heated or cooled. However, a temperature sensor that detects the temperature of the water in the container 2 is attached to the outer bottom surface of the container 2 so that the water in the container 2 can be heated and 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 made of hard foaming 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 each pump 4, 1
6 prevents the formation of dew on the outer wall. The lid side heat insulating material 37 made of hard foamed urethane is also provided inside the lid 3.
To prevent dew condensation on the outer wall of the lid 3. Furthermore, since cold water flows through the third water passage 23 on the cooling side, dew condensation easily occurs on the outer wall of the third water passage 23.
Since they are embedded together in the container-side heat insulating material that covers the outer wall of the container 2, 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 water in the container 2 is once boiled to remove the chlorine component contained in the water, the circulation side switching valve 21 is switched to the second water passage 22 side, and the circulation pump 16
And the heater 26 is energized to heat the water in the container 2 with the boiler 25 and circulate the water in the second water passage 22 and the container 2. That is, the water in the container 2 is sucked from the suction port 18 of the circulation pump 16 and is pressure-fed from the discharge port 19 to pass through the first water passage 20 and the second water passage 22 and then to the container 2
Reflux into. At this time, the water is heated by the heater 20 when passing through the heating container 21, and by continuing this operation, the temperature of the water in the container 2 rises and reaches boiling. Further, at this time, since the water passes through the water purification agent 33, the removal of chlorine components such as chlorine is promoted.

To cool the boiled water to the heat retention temperature,
The circulation side switching valve 21 is switched to the third water channel 23 side,
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 passing container 24 is lowered by the Peltier effect, the heat of the water passing through the water passing container 24 is taken, and the heat radiating member 26 pressed against the heat radiating side. To the main body 1 by blowing the air from the blower 27.
Exhaust to the outside. By continuing this operation, the water passing through the heat exchanger 28 disposed in the middle of the third water passage 23 is cooled to cool the container 2
By refluxing the water inside, the water 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).

In order to keep the boiling water warm at a high temperature, for example, around 95 ° C., the same operation as in the boiling operation is performed until the predetermined warm temperature is reached in accordance with the decrease in the temperature of the water in the container 2. Well, cool water at low temperature, eg 10 ° C
In order to keep cool before and after, the same operation as the cooling operation may be performed until the predetermined cool temperature is reached in accordance with the rise in the temperature of the water in the container 2.

Further, the operation on the deriving side will be briefly described.
When the water in the container 2 is heated, the outlet side switching valve 15 is switched to the side of the reflux pipe 14 so that the path between the bottom part and the upper part of the container 2 is in communication, that is, in the state where the circulation path is formed, By operating the derivation pump 4, the water in the derivation route 8 circulates and replaces, and unnecessary components in the water that have not been heated in the derivation route 8 can be removed.

When the water 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 in the same manner as described above before the discharge, and the discharge pump 4 is operated. For example, the water in the lead-out path 8 is circulated and replaced, and the temperature of the water in the lead-out path 8 is made substantially equal to the temperature in the container 2. After this circulation operation is completed, the outlet switching valve 15 is switched to the outlet pipe 13 side, and water is led out from the outlet 9. The outlet side switching valve 15 described above
By deriving a small amount of water by performing the operation of
That is, even when the water in the outlet path 8 is discharged, the water kept at a high temperature or the water kept at a low temperature lower than the ambient temperature (outside air temperature) will not be led out.

Further, if kept cold at a low temperature for a long time, there is a possibility that various bacteria will propagate in the derivation route 8. However, in the derivation route 8 in the same manner as above, during or after the heating of water. By circulating hot water, the circulation path 8 and the reflux pipe 14 can be sterilized, which is hygienic.

Further, since the position of the boiler 22 is arranged at a position higher than the full water level in the container 2 (A water level in the figure), even when cooling / cooling the water to a low temperature below the ambient temperature, Since the water in the container 2 does not flow into the boiler 22 side and the boiler 22 is not exposed to cold water, the temperature of the boiler 22 does not easily drop, and it is possible to simplify the attachment of a heat insulating material to the boiler 22 to prevent dew condensation. Furthermore, since the boiler 22 is located above the heat exchanger 23, it is possible to reduce the cooling effect even when the heat exchanger 23 is operating.

Next, the configurations of the pot purification unit 24a and the mineral addition unit 24b of the present invention will be described with reference to FIG.

FIG. 1 (a) is a sectional view of the second water channel 22 and the third water channel facing the discharge ports. 1B is a sectional view taken along line AA of FIG. 1A, and FIG. 1C is a sectional view taken along line BB of FIG. As is clear from these figures, the purification unit 2
4a and the mineral addition part 24b are provided so as to project inward from the inner wall surface of the container 2. 33 is a water purification agent, 34 is a mineral additive, 38 holds these parts so as not to fall and spread, and these parts 3
It is a holding member having a large number of through holes so that the water that has passed through 3, 34 can flow out quickly. 35 is a water purification agent 3
3 and the mineral additive 34 through the flow of water through the container 2
A deflecting member that quickly deflects the inner wall surface, and 36 is a water collecting portion that temporarily collects water that has passed through by providing a step in a part of the deflecting member. 37 is a water dispersion member for widely dispersing the water discharged from each of the water channels 22 and 23 above the water purification agent 33 or the mineral additive 34 to improve the contact between the water and each of the agents 33 and 34, Reference numeral 39 is a partition wall that separates the purification unit 24a and the mineral addition unit 24b.

First, the operation when water is circulating on the cooling means side will be described. The water that has been drawn from the inside of the container 2 to the third water passage by the circulation pump 16 and has passed through the cooling means 28 and cooled is led to the mineral addition unit 24b from the discharge port. The water thus drawn out is first dispersed horizontally by the water dispersion member 37 and then uniformly drops onto the mineral additive 34 from above. As a result, the water that has passed through the mineral additive 34 passes through the holes provided in the holding member that holds the mineral additive 34, and falls uniformly on the deflecting member 35.
The water that has dropped onto the deflecting member 35 is collected in a water collecting portion 36 provided so as to have an opening portion at a portion of the deflecting member 35 on the inner wall surface side of the container 2, and from this opening portion along the inner wall surface of the container. It is led out into the container 2. At this time, if the deflecting member 35 is provided so as to incline toward the inner wall surface of the container 2 low, the collected water has a momentum and is more effectively discharged along the inner wall surface of the container 2.

Even when the water circulates on the heating side, the water is heated and purified by the same operation.

With such a configuration, each water channel 22, 23
Not only when the water is being discharged from the water, but also after the circulation pump is stopped and the circulation is completed, the water that has passed through late from the water purification agent 33 and the mineral additive 34, or the accumulated water falls. The jarring dropping noise that occurs is eliminated. That is, according to the configuration of the present invention, even if such a small amount of water falls from any position below the water purification agent 33 and the mineral additive 34, it is received by the deflecting member 35, and once the water collecting section has a step. Since it is collected in 36 and is led out from the opening in the vicinity of the inner wall surface of the container 2, it is surely led out into the container along the inner wall surface of the container 2 and is not dropped directly to the water surface in the container 2. No unpleasant dripping noise is produced.

In this embodiment, the purification section 24a and the mineral addition section 24b are integrally provided, but they may be provided separately. If it is provided separately, it is possible to attach only the necessary parts and it is possible to realize purification and mineral addition according to the water quality of each place according to the taste of the user.

Furthermore, in this embodiment, the water purification agent 33 and the mineral additive 34 were used, but other than these parts,
What changes water, for example, tea leaves (Japanese tea, black tea, barley tea, etc.), coffee beans and the like required for drinking can also be used. In this case, these parts can be used either on the heating means side or on the cooling means side.
In particular, the present invention is a structure useful for making cold tea or cold coffee delicious.

[0050]

As is apparent from the above description, according to the first means for solving the problems of the present invention, the water in the container is first
By heating and boiling while circulating between the heating means and the container, some unnecessary components in the water (calcium, musty odor, trihalomethane, etc.) are removed, and then the boiled water is circulated between the cooling means and the container. This rapidly cools the delicious water to the temperature range. By providing a mineral addition part in this cooling circulation path and passing the mineral addition part while cooling and circulating the water, it is possible to add a mineral component to the water and produce delicious water at a low temperature. However, it is desirable to adjust the mineral component to a very small amount,
When excess minerals are released into water, it not only spoils the deliciousness of the water, but also causes the possibility of depositing as scale when the water becomes cold. Therefore, it is possible to adjust the content of the mineral additive to an appropriate content by making the mineral additive have a low solubility and passing it while cooling and circulating.

According to the second means for solving the problems of the present invention, the water discharged from the circulation path is received by the water dispersion member and horizontally dispersed so that the circulating water sufficiently diffuses and comes into contact with the mineral additive. To do. Furthermore, if water drops from the bottom of the mineral addition part as it is, an unpleasant dripping sound is generated.In order to prevent this, the water that has passed the mineral additive to the bottom of the mineral addition part is guided along the inner wall surface of the container. The deflecting member deflects the flow so that it falls. As a result, water does not drop from the bottom of the mineral additive to the water surface in the container as it is, but drops along the inner wall surface, so that no dripping sound is generated and quiet and comfortable water purification can be realized.

A third problem solving means is the same as the first problem solving means, wherein a purifying section is provided in the circulation path on the heating means side,
Purification is performed while boiling water in the container.
As a result, the water passing through the purification unit is in a high temperature state,
When contacting with a cleaning agent such as activated carbon, unnecessary components (calcium,
Since mold odor, trihalomethane, etc. are in a very activated state, unnecessary components (chalk, mold odor, purifier, etc.)
(Trihalomethane, etc.) can be reliably removed, and discomfort does not occur even in hot water.

The fourth problem solving means is a structure for more effectively carrying out the second and third problem solving means. In order to more reliably cause the water passing through the mineral addition section or the purification section to follow the inner wall surface of the container, a deflecting member provided in each is formed with a water collecting section for collecting the passed water and forming a large flow, The water collected in this water collecting part is led out into the container from the opening part of the water collecting part along the inner wall surface of the container. The amount of water discharged from the circulation path is not large enough to create a large flow, depending on the performance of the circulation pump. Moreover, in order to horizontally disperse the water by providing a water dispersion member so as to contact the mineral additive or the purifying agent as much as possible,
If a small amount of water is further dispersed and the water received by the deflecting member is to be guided out along the inner wall of the container as it is, the space between the deflecting member and the inner wall surface of the container must be very narrow. The fine structure that requires such precision causes troubles such as failures and route clogging. Therefore, in order to ensure that water is discharged along the inner wall surface of the container even if the gap provided between the inner wall surface of the container and the deflecting member is slightly large, a part of the deflecting member facing the inner wall surface of the container is provided. The step can be provided to form the water collecting portion, and the portion where the inner wall surface of the container and the water collecting portion face each other are opened, so that the noise reduction can be surely realized.

According to the fifth means for solving problems, the purifying section and the mineral addition section of the third or fourth means for solving problems are integrated. This allows the pot to be compact and have high performance.

According to the sixth problem solving means, in the third or fourth problem solving means, the purifying section or the mineral addition section is made detachable. As a result, when each part is unnecessary, it can be freely attached and detached, and the convenience of handling is enhanced.
