[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid storage container, and more specifically, a hot water storage tank for heating the content liquid to keep it warm after boiling it.
The present invention relates to a liquid storage container including a water storage tank that cools and keeps an internal solution cold.

[0002]

2. Description of the Related Art Conventionally, as boiling water, cold water, or hot water cooling, it is disclosed in Japanese Patent Laid-Open No. 19323/1992.
There is one using one liquid storage tank disclosed in Japanese Unexamined Patent Application Publication No. 2 and JP-A-3-112520.

[0003] These already known devices are provided with a combination of a heating means for heating an internal solution to keep it hot and keeping it warm in one liquid storage tank and a cooling means for cooling the internal solution to keep it cool. Whether the hot water is stored or the water is stored can be determined by working the tiger, and the hot water is cooled by operating the heating means to boil the internal solution and then operating the cooling means.

Therefore, the internal solution to be stored can be cooled with hot water, and good quality cold water can be obtained.

[0005]

However, if the hot water is cooled in one tank, the cold water and the boiling water cannot be obtained at the same time, and the liquid storage container becomes a water storage container for keeping cold. . Therefore, boiling water must be prepared separately when it is desired to obtain medium temperature hot water suitable for extracting gyokuro tea and melting milk for infants.

An object of the present invention is to solve such a problem, and to simultaneously perform hot water storage in a hot water storage tank and water storage in a water storage tank, particularly hot water cooled storage water using boiling water made in the hot water storage tank. The main purpose is to provide a liquid storage container capable of supplying both of them at the same time.

[0007]

In order to achieve the above-mentioned object, the present invention provides a hot water storage tank, a water storage tank, and heating means for heating an internal solution in the hot water storage tank to bring it to a boil and then keep it warm. Cooling means for cooling and keeping the internal solution in the water storage tank cool, hot water pouring path for pouring the internal solution in the hot water storage tank to the outside of the body by an electric pump, and internal solution in the water storage tank to the outside of the body by an electric pump The water storage pouring path for pouring out,
The hot water tank has a hot water supply channel for sending the solution in the hot water tank to the water tank, the cooling means uses a refrigeration cycle, the water tank is smaller than the hot water tank, and the water tank is shorter than the hot water tank. Can be due to the small
It is preferable that a refrigerating compressor for cooling means is installed in an empty space.

[0008]

According to the above-mentioned structure of the present invention, it has two tanks, a hot water storage tank and a water storage tank, and the inner solution is heated by the heating means in the hot water storage tank to bring it to a boil, and then the temperature is maintained. Since it is possible to cool the internal solution by the cooling means in the tank and keep it cool at the same time, hot water and cold water can be poured out at any time as long as the electric pump in the hot water pouring path and the electric pump in the hot water pouring path work properly. Of course, both can be poured out and used to mix hot water with cold water to obtain hot water of a desired temperature.

In the water storage in the water storage tank, an electric pump in the hot water storage water supply channel is operated to supply the internal solution boiled in the hot water storage tank to the cooling tank for storage, thereby obtaining high-quality cold water. Even if cold water is mixed with the hot water, high quality hot water having a desired temperature can be obtained. Moreover, the cold water for cooling the hot water in the water storage tank can be obtained by receiving the hot water that has been boiled in the hot water storage tank to cool it. Since they can be performed in parallel, it is possible to supply hot water and cold water which has been cooled by hot water almost at the same time.

In particular, the cooling means uses a refrigeration cycle, the water storage tank is shorter than the hot water storage tank, and the water storage tank is shorter than the hot water storage tank. In the configuration with the refrigeration compressor installed, the cooling means using the refrigeration cycle can efficiently achieve cooling even from the hot water in the water storage tank in a short time, and the refrigeration compressor for the refrigeration cycle is relatively large. However, because the water storage tank is smaller than the hot water storage tank, it can be installed by using the empty space of the hot water storage tank, so the whole can be compacted and the installation space is small and easy to use. Becomes
Moreover, even if the water storage tank is smaller than the hot water storage tank and has a small volume, the hot water storage tank is used to keep hot water by boiling water inside the hot water storage tank, and the hot water storage tank is used every time the water solution in the water storage tank decreases or disappears. It is possible to supply water by replenishing the hot water solution in the tank by replenishing it so that the hot water and the hot water can be stored at the same time, and the hot water solution and the hot water solution can be poured and used as appropriate. It is convenient.

To 163 and the electric pump 14 are also connected appropriately. 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 is advanced or repeated according to the power failure judgment, the pump operation processing subroutine is executed, and the electric motor is operated 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 during 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. .

Thus, each 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 of 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 has been switched to the temperature maintaining mode. Therefore, the cooling operation memory is set to send water and the cooling timer is started.

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, when there is a memory during the water heating operation when the water heating key is turned on, this is the operation of the water heating key in the water heating mode. 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 in a state where 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 determined 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 ode 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 automatic mode, the hot water storage tank 1 and the hot 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 hot 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, the 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 automatic setting key is turned on, the automatic 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.

When the liquid amount is 1 liter or more, the timer is activated by turning on the timer time LED according to the timer auto set time and the buzzer sound and turning on 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 determination 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 the boiling water is immediately ended in the boiling water mode and the heat retention is started. Therefore, the boiling memory is reset and a buzzer sound is issued to inform that there is no need for the boiling water. .

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 worry 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 80 ° C or less. 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 sub-heater are turned on to enter the water heating 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.

When 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 mode is 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 the 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 boiling or the removal of scaly by continuing boiling for a predetermined time has ended, the boiling is informed and the boiling LED blinks five times. To display this.

After that, 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 the 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 captured and the predetermined data value has been reached, but if the predetermined data amount has not been captured. 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.

Further, even if the automatic mode is not set in block 15, the process directly goes through the other process and returns to the process after the power failure process.

According to the main feature of the present invention, it has two tanks, a hot water storage tank and a water storage tank, in which the internal solution is heated by the heating means to boil and then keep warm Since it is possible to cool the internal solution by the cooling means in the water storage tank and keep it cool at the same time,
Hot water and cold water can be poured out and used at any time as long as the electric pump in the hot water pouring path and the electric pump in the hot water pouring path are appropriately operated, and both can be poured to mix the cold water with the hot water. You can easily get hot water.

Further , in the water storage in the water storage tank, an electric pump in the hot water storage water supply channel is operated to send the internal solution boiled in the hot water storage tank to the cooling tank to be used for water storage. Even if cold water is mixed with the hot water, high quality hot water having a desired temperature can be obtained. Moreover, the cold water for cooling the hot water in the water storage tank can be obtained by receiving the hot water that has been boiled in the hot water storage tank to cool it. Since they can be performed in parallel, it is possible to supply hot water and cold water which has been cooled by hot water almost at the same time.

In particular, the cooling means uses a refrigeration cycle, the water storage tank is shorter than the hot water storage tank, and the water storage tank is shorter than the hot water storage tank. According to the configuration in which the refrigeration compressor of is installed, cooling from the hot water in the water storage tank can be efficiently achieved in a short time by the cooling means utilizing the refrigeration cycle.
The refrigeration compressor for the refrigeration cycle is relatively large, but it can be installed by utilizing the empty space of the hot water storage tank, which is possible because the water storage tank is smaller than the hot water storage tank, so the whole is compact. Therefore, the installation space is small and it is easy to use. Moreover, even if the water storage tank is smaller than the hot water storage tank and has a small volume, the hot water storage tank is used to keep hot water by boiling water inside the hot water storage tank, and the hot water storage tank is used every time the water solution in the water storage tank decreases or disappears. It is possible to supply water by replenishing the hot water solution in the tank by replenishing it so that the hot water and the hot water can be stored at the same time, and the hot water solution and the hot water solution can be poured and used as appropriate. It is convenient.
