However, with the above-mentioned conventional structure, so-called hot water cooling water obtained by cooling once boiling water cannot be obtained. In other words, it is impossible to cool the hot water by treating it in the body while having the hot water storage portion.

Therefore, when the temperature of the hot water stored in the hot water storage section is lowered by mixing it with the cold water stored in the water storage section to make gyokuro or food and drink for infants, the cold water that is not boiled is mixed. However, since the chlorine content and odor particles are mixed in, there is a problem in that the quality of the content liquid boiled with water is deteriorated.

When it is desired to cool the water in the water storage part, it is not convenient to use because it is necessary to separately pour water into the water storage part from outside the body.

On the other hand, once the water is boiled, carbon dioxide gas and oxygen are released by the boiling, so it is not good to cool it as it is to obtain cold water. The result is a so-called unsharp taste. Also, since water has a high specific heat,
It is inefficient to cool water that has been boiled once. Therefore,
If a high-capacity refrigerating compressor is used as the cooling means, the cooling means becomes large in size together with other necessary equipment, and the noise becomes large, making it unsuitable for small-scale use at home.

An object of the present invention is to solve the above-mentioned problems, and hot water and hot water can be stored at the same time, and both can be freely poured out, and if necessary, the content liquid after boiling can be cooled in a delicious water bath.

Corresponds to the position of the pouring outlet 3a and the position of the pouring outlet 13a of the water pouring channel 13 of the water storage section B.

Both the lids 5 and 15 are formed in a hollow body made of synthetic resin, and the openings 23a and 23c are sealed by a seal packing 40 attached to the outer periphery, and the hollow portions are insulated from the hot water storage tank 1 and the water storage tank 11 by air insulation. The heat is prevented from escaping upward. In some cases, the lids 5 and 15 may be filled with a heat insulating material.

On the lid 5 of the hot water storage portion A, the content liquid is boiled,
Alternatively, a steam vent passage 96 is provided to allow steam generated when heated to a high temperature to escape to the outside. Thereby, it can be avoided that the inside of the hot water storage tank 1 is abnormally pressurized.

The hot-water pouring path 3 and the hot-water supply path 7 are branched and connected to a common take-out path 91 connected to the bottom of the hot-water tank 1, and the electric pump 4 and the electric pump 8 are provided on the way. A drain port 92 is also provided so as to extend the extraction path 91 downward. The drain port 92 is always closed by pressing a stopper or a tube cap integrally formed with an elastic tube cap 93 with a spring and pressing the same. This closing method is free, and various known ones can be adopted, but it is preferable that the opening and closing are easy.

The tube cap 93 can withdraw a drain lid 99 provided on one side of the lower portion of the body C and pull it out through an opening 98 which is in an open state to drain the drain. The drawer lid 99 has a shallow container portion 99a so that the tube camp 93 can be received at the accommodation position in the container C.

A concave portion 95 is provided at a portion of the lid 15 facing the connection portion of the opening 23c with the hot water storage water supply passage 7 so as to prevent the flow of the hot water sent through the hot water storage water supply passage 7 from colliding with each other. The specific shape of the recess 95 can be variously designed.

In the portion of the opening 23c of the water storage tank 11 where the connection hole 23e of the hot water supply passage 7 is opened,
FIG. 7B shows a cartridge-type water quality improving means 202 in which the water quality improving material / water purification material 201 is accommodated in the water supply path to the water storage tank 11 of the hot water storage water supply passage 7 by utilizing the recess 95. 7 (b), and is detachably fitted to the cylindrical portion 23w on the inner surface of the opening 23c formed by the shoulder member 23, and the water supplied from the hot water storage water supply passage 7 is, for example, the porous plate 202a at one end. The water is once received through the water quality improving / purifying material 201, and then is sent into the water storage tank 11 through, for example, a perforated plate 202b as a water sprinkling means provided on a part of the peripheral wall. However, it goes without saying that the water quality improving means 202 may be provided in a part of the hot water supply passage 7. In this case, the same water sprinkling effect can be obtained if the water sprinkling means has a structure in which the water feed end of the hot water storage water passage 7 is made to face the upper part of the water storage tank 11 as a shower pipe.

If the water quality improving means 202 can be at least mineralized, it can restore a part of the deterioration of sharpness due to the removal of carbon dioxide gas and oxygen by boiling, and in this sense, it is sufficient if it contains a hard component. However, a water purifying material such as activated carbon can also be accommodated to perform a water purifying function, and if coral sand is used as the hard component, it contains calcium carbonate and magnesium carbonate, so that water is passed. At the same time as mineralizing the content liquid, it is possible to solubilize the carbonic acid and restore the depletion of carbon dioxide gas, making it possible to make the taste of the water cooled sufficiently sharp.

Moreover, the content liquid that has passed through the water quality improving means 202 is introduced into the water storage tank 11 from the upper space of the water storage tank 11 in a sprinkling state through the perforated plate 202b, so that the content liquid comes into good contact with air. However, since it accumulates in a state where air is mixed, it is possible to accelerate the solubilization of oxygen and restore it, thereby making the water more round.

The outlet 13a of the water outlet 13 of the water reservoir B
As shown in FIG. 5, the portion is supported and guided by a liquid amount sensor cover 97 provided around the water storage outlet 13, and is stabilized. The liquid amount sensor cover 97 is formed integrally with itself. Attach the mounting pieces 97a on both sides of the upper end to the shoulder member 2
It is screwed to the back side of 3.

Further, the body C has a control circuit 100 as shown in FIG. The control circuit 100 includes a microcomputer 101 and a power supply circuit 10 as shown in FIG.
2, a combination of the drive circuit 103, and the heater 2, the electric pump 4, the temperature sensor 54, and the liquid amount sensors 61 to 63 of the hot water storage section A are connected to these as appropriate.
Peltier element, which is the cooling means 12 of the
The liquid volume sensors 161-163 and the electric pump 14 are also appropriately connected. Further, the operation panel 58 and the electric pump 8 are also connected.

The operation control by the control circuit 100 will be described below with reference to the flow charts shown in FIGS. In the following control, the heater 2 is divided into a main heater for heating water and a sub-heater for keeping heat, and the heating control of the liquid content in the hot water storage tank 1 is performed.

When the power is turned on, the program starts and the processing of block 1 shown in FIG. 11 is performed.

In this process, first, initialization such as clearing various memories and setting initial data is performed. In the present embodiment, the content liquid is boiled at the same time when the power is turned on, and the control for keeping it warm is automatically achieved.
Therefore, the boiling memory is set by default.

Then, the start of the program is notified by a buzzer sound, and after the program progresses or is repeated according to the power failure determination, a pump operation processing subroutine is executed, and an electric drive is performed depending on whether or not the pouring key is operated. Turn on the pump.

Next, the abnormality detection of various sensors such as the temperature sensor of the water storage section B and the temperature sensor of the hot water storage section A and the display and processing corresponding thereto are performed. If there is no abnormality, the liquid amount determination processing subroutine is executed, and the hot water storage tank 1 and the amount of liquid in the water storage tank 11 is detected.

In the next blocks 2 and 3 shown in FIG. 12, the processing required when the cooling key and the water supply key are turned on is performed.

In block 2, when the cooling key is turned on, if there is a memory under cooling operation, the cooling key operation is performed again in the state where the cooling operation mode is actually set, so the cooling output is turned off and the cooling is performed. -The cool LED is turned off, the cooling operation memory and the cooling timer are reset to release the cooling operation mode. If there is no memory during cooling operation, set the cooling operation memory, start the cooling timer, and enter the cooling operation mode. .

As a result, every time the cooling key is turned on, the cooling operation mode is set and released by the rotary system.

In block 3, when the water supply key is turned on, if the water is not kept warm, the boiling water in the hot water storage tank 1 has not been completed. Therefore, the water supply is not performed, and NG is notified as an operation error.

While the temperature is being maintained, the boiling of the content liquid in the hot water storage tank 1 is completed and the mode is switched to the temperature maintaining mode. Therefore, the cooling operation memory is set and the cooling timer is started in order to send water.

As a result, it is possible to simultaneously cool the water in the water storage section B together with the water supply. This is because the rising of the cooling in the water storage section B is slow, so that the cooling operation is started together with the water supply.

In the next Glock 4 shown in FIG. 13, if there is a memory in the water heating operation when the water heating key is turned on, it is the operation of the water heating key in the water heating mode, so the heater output is turned off and the boiling The heat retention LED is turned off, the boiling water operation memory is reset, and the boiling water mode is released.

On the other hand, when there is no memory during the water heating operation, the water heating key is operated when the water heating mode is not set. Therefore, the water heating operation memory is set and the water heating mode is set.

As a result, in addition to the fact that the water heating is started when the power is turned on, it is possible to manually release and set the water heating mode at any time by the rotary system.

Finally, it is decided whether to proceed to the next block 5 in the figure or to jump to the block 9 shown in FIG. 16 depending on whether or not there is an empty cooking memory.

In block 5 shown in FIG. 13, when the auto mode setting key is turned on, it is determined whether or not the liquid amount in the hot water storage tank 1 is 1 liter or more, and if not, an NG is notified as an operation error.

In the auto mode, the hot water storage tank 1 and the water storage tank 1 are used to cool the water by sending the content liquid after boiling in the hot water storage tank 1 to the water storage tank 11 to cool and keep it cool.
The setting of the automatic mode is prohibited because the amount of the liquid that cannot be stored and stored in both the hot water and the hot liquid is sufficient for both of the above cases.

When the liquid amount in the hot water storage tank 1 is 1 liter or more, the operation display LED is turned off and the cooling output is turned off so that the cooling operation is stopped even if the cooling operation is performed.

Then, the auto mode memory is set to be in the auto mode setting state, and the buzzer sound and the lighting of the auto LED indicate the auto mode setting state.

In block 6 shown in FIG. 14, processing corresponding to the timer boiling key being turned on is performed.

When the timer boiling key is turned on, the operation display LED is turned off, the cooling output is turned off, and the corresponding timer time LED is turned on and the buzzer is turned on depending on whether the timer boiling set time is 6 hours or 9 hours. The timer boiling mode is set and displayed by the sound and the lighting of the timer boiling LED.

In block 7 of FIG. 15, when the timer auto setting key is turned on, the auto mode operation is performed in accordance with the timer setting time. If the liquid volume is not more than 1 liter, NG is notified and the timer auto is not set.

If the liquid amount is 1 liter or more, the timer is turned on by turning on the timer time LED according to the timer auto set time and turning on the buzzer sound and the timer auto LED as in the case of the timer boiling in the block 6. Set and display the auto mode.

In block 8 shown in FIG. 16, processing is performed depending on whether or not there is a timer memory.

If there is a timer memory, a timer operation is performed to determine whether the post-timer has expired. If the timer has expired, the timer memory is reset to cancel the timer setting, and the process returns to the power failure judging section of block 1 through the other processing shown in FIG.

If the timer has not expired, the process directly returns to the power failure judging unit.

In block 9 shown in FIG. 16, if there is a hot water boiling memory, it is determined whether the temperature is 105 ° C. or higher. If the temperature is 105 ° C. or higher, an empty cooking memory is set and the boiling memory is reset. Make sure to take measures to prevent empty cooking.

In block 10 shown in FIG. 16, when the reboil key is turned on, there is a boiling memory, and if the content liquid in the hot water storage tank 1 is not higher than 80 ° C., the boiling of the content liquid in the boiling water mode is completed. Since it is the operation of the re-boiling key in the state where it has not been performed, the boiling memory is set so that the boiling is continued, and the buzzer sounds to inform that the boiling mode is being performed.

If the content liquid is 80 ° C. or higher, it means that it is immediately after finishing the boiling in the boiling mode and shifting to the heat retention. Therefore, the boiling memory is reset and a buzzer sound is issued to notify that boiling is not necessary. .

Further, when the reboil key is turned on, there is no boiling memory, and there is no empty cooking memory, the reboil key is operated when not in the water heating mode, and there is no concern of empty cooking. Reset and set the boiling memory so that re-boiling will occur,
This is announced by a buzzer sound.

When the reboil key is turned on and there is no boiling memory, it is possible to switch to the boiling water mode, but if there is an empty cooking memory, there is a danger of empty cooking in the boiling water mode unless the content liquid is below 80 ° C. Therefore, the process returns to the power failure determination unit of block 1 and is processed so that the water heating is not performed as it is. However, if the content liquid is 80 ° C. or lower, there is no concern about empty cooking, so the empty cooking memory is reset and the boiling memory is set so that re-boiling is performed.

In block 11 shown in FIG. 17, it is again determined that there is no emptying memory and the content liquid is 80 ° C. or lower. If this is not satisfied, the process proceeds to step # 1-1 of block 1. The boiling and heat-retaining LEDs are alternately blinked to notify the danger of empty cooking, and after the main heater and sub-heater of the block 1 are controlled to be turned off, the procedure after the power failure determination unit is repeated through other processing to allow empty cooking. Do not be discouraged.

In block 11, there is no empty cooking memory, 8
Only when it is confirmed that the temperature is 0 ° C. or lower, the boiling memory is set to enable the water heating mode, and the process proceeds to the process of block 12 and subsequent steps shown in FIG. 17, otherwise, the process of block 12 is performed as it is. Move on to.

In block 12, if there is a boiling memory after the above processing, the main heater and the sub heater are turned on to enter the boiling water mode, and the boiling LED is turned on.
Is turned on to indicate that the apparatus is in the water heater mode, and then the flow proceeds to the processing of block 14 shown in FIG.

If there is no boiling memory in block 12, the sub-heater is turned off when the temperature is higher than the predetermined temperature by 1 ° C. and the sub-heater is turned on when the temperature is lower than the predetermined temperature because the temperature is in the heat retention mode. Make sure that the temperature is kept warm.

Next, moving to the processing of block 13 in FIG.
If not, the process returns to the process after the power failure determination through the other processes in FIG.

When the cold storage is in the automatic mode and the water storage tank 11 is on, and when the cold storage is in the automatic mode and there is a water storage memory, the processing shifts to the block 16 shown in FIG. To do.

Then, when the cold storage is not in the automatic mode and the water storage tank 11 is not on, and when the cold storage is in the automatic mode and there is no water storage memory, the processing shifts to block 17 shown in FIG. To do.

In block 14 shown in FIG. 18, following the boiling mode process in block 12, while the content liquid in the hot water storage tank 1 does not reach 90 ° C. or higher, the boiling data is reset and the power failure process in FIG. Then, the water heating mode in the hot water storage tank 1 is continued.

When the content liquid reaches 90 ° C. or above,
When the reboil key is turned on, it is determined that the descaling mode is set, and the boiling data is fetched every time 30 seconds elapse, and the descaling mode is not set unless the reboil key is turned on. After the boiling data has been fetched, when the addition of the predetermined boiling data has been completed, the processing shifts to block 15.

In block 15, the end of the boiling safety timer is watched, and if it has ended, it is judged that the boiling or the removal of the scaly by continuing the boiling for a predetermined time has ended, the boiling is informed and the boiling LED blinks five times. To display this.

Thereafter, the boiling LED is turned off to reset the boiling memory, and in the automatic mode, in order to shift to water supply and cooling, the water supply memory is set and the cooling timer is started to start block 16 shown in FIG. Move to.

If the boiling safety timer has not expired in block 15, the process ends in the boiling ending process only when the predetermined data amount has been fetched and the predetermined data value has been reached, but if the predetermined data amount has not been fetched. Performs data acquisition processing, returns to the power failure processing after the other processing of FIG. 11, and has the predetermined data amount, but if the predetermined data value has not been reached, the other processing is performed and the power failure processing is performed. Return.

Also, if the automatic mode is not set in block 15, the process returns to the process after the power failure process through the other processes.

In block 16 shown in FIG. 19, the electric pump 8 is operated until the water storage tank 11 becomes full or the amount of the liquid content in the hot water storage tank 1 becomes 300 ml or less.
Is turned on so that the content liquid after boiling in the hot water storage tank 1 is sent to the water storage tank 11, and is cooled and kept cool in the water storage tank 11.
