  In the display / operation unit 74, as shown in FIG. 4A, a display unit 100 for displaying time and the like is arranged on the upper center side. The display unit 100 is configured by, for example, an LCD (Liquid Crystal Display), and as shown in FIG. 4B, a clock / timer time display unit 102, a timer display unit 104, a stage display unit 106, a start display unit 108, An end display unit 110 is set. The clock / timer time display unit 102 displays setting contents such as a cleaning process and a start time of an energy saving mode, which will be described later, in addition to a normal clock display.

  Further, on the center side of the display / operation unit 74, for example, as a setting operation unit for performing reservation setting or the like, an addition switch (SW) 112 for adding a value such as a set time, a subtraction switch for subtracting a value (SW) 113 is arranged in the central portion, and on both sides thereof, a setting switch (SW) 114 for switching to or canceling the setting mode, an energy saving switch for switching to or canceling the energy saving mode (SW) 116, an energy saving operation display unit 118 for displaying ON / OFF of the energy saving SW 116, a timer / clock switch (SW) 120 for adjusting a timer and time, a start / stop switch for starting or stopping ( SW) 122 is arranged. Under these switches, an automatic high-temperature water circulation mode display unit 124 for notifying the user that a cleaning process using high-temperature water circulation described later is being performed is arranged.

  At both ends of the display / operation unit 74, for example, operation units for setting a supply temperature are arranged. As an example of the forced temperature change switch, a high temperature setting command (SW) 126 for performing or canceling a high temperature setting different from the normal operation, a cold water setting command or canceling the cold water setting different from the normal operation A switch (SW) 128 is arranged. Further, in the vicinity of the high temperature setting switch 126, a normal temperature display unit 130 that lights and displays a set temperature (for example, 85 [° C.]) during normal operation as a first operation mode is displayed by lighting when forced high temperature. A high-temperature display unit 132 is installed, and these are configured by lamps such as LEDs (Light Emitting Diodes). In the vicinity of the chilled water setting switch 128, there are a temperature display unit 134 for indicating that the first chilled water set temperature (for example, 8 [° C.]) and a second chilled water set temperature (for example, 12 [° C.]). A temperature display unit 136 for displaying this by lighting is installed, and these are also composed of lamps such as LEDs.

The part 144 is installed.

  Next, the configuration of the display / operation unit 74 will be described according to the operation content of the drinking water supply device.

A Initial state

  When the power is turned on, the cooling device 22 for cooling the drinking water 4 is turned on (set temperature: 8 [° C.]), and the power supply control (for example, ON / OFF control) for the hot water heater 42 for warming the drinking water 4 is turned off. Put it in a state. In this case, in order to give priority to hot water supply, operations of the lock release SW 142 and the hot water supply SW 138 are accepted. This is the case of using the initial air vent. However, the above description when the power supply control for the hot water heater 42 is in the OFF state is a case where the temperature detected by the hot water sensor 54, that is, the hot water temperature is, for example, 40 [° C.] or less.

  In the clock display of the display unit 100, the hour and the minute are displayed by blinking “-:-”, and the time is determined by pressing the addition SW 112, the subtraction SW 113, and the setting SW 114.

  The power supply control of the hot water heater 42 is executed by, for example, long pressing of the start / stop SW 122. For example, as a long pressing time in the OFF state of the power supply control, for example, by pressing for 2 [seconds], for example, as the set temperature of the ON operation, The setting is 85 [° C.]. If, for example, 2 [seconds] is pressed as the long pressing time in the ON state, the OFF state is set. However, the hot water sensor 54 using the thermistor can also use the self-heating characteristic to determine the presence or absence of water and operate the power supply control of the hot water heater 42 to be turned ON / OFF.

  When the power supply control of the hot water heater 42 is shifted from the OFF state to the ON state, the energy saving mode is turned OFF. The same control is performed when returning from the power failure state to the power supply state. However, when the time of the energy saving mode has been set, the time is stored in the storage unit 156 (FIG. 5).

  The time setting method is executed in the clock display mode, and the time setting method in the energy saving mode is executed in the energy saving time setting mode.

B Water supply operation

  When the water supply SW 140 is continuously pressed in the press-permitted state (unlocked), the cold water solenoid valve 34 is controlled to be in the open state, and water is supplied. The cold water solenoid valve 34 is controlled to be in an open state only while the water supply SW 140 is being pressed, and does not accept the operation of the hot water SW 138 while the water supply SW 140 is being pressed. Since water supply and hot water supply are not performed simultaneously, safety is ensured.

C Cold water switching operation

  When the cold water setting SW 128 is continuously pressed, the setting of the cold water temperature is changed. For example, if pressing is continued, the set temperature is changed as follows: 8 [° C.] → 12 [° C.] → 8 [° C.] →.

D Unlock operation

  When the unlock SW 142 is pressed, the hot water supply SW 138 and the water supply SW 140 are unlocked, and the pressing is permitted. At this time, for example, the lock release display unit 144 set on the lock release SW 142 is lit in red to indicate that the lock is released. This unlocking state is finite, for example, when there is no operation of hot water supply SW138 for 10 seconds, the unlocking is invalidated, the unlocking display unit 144 is turned off, and the locked state is displayed.

  When the unlock SW 142 is pressed again during unlocking, the unlocking becomes invalid, and the unlock display unit 144 turns off from red and goes into the locked state.

  When the hot water supply SW 138 or the water supply SW 140 is pressed during unlocking, for example, 10 seconds after the hot water supply SW 138 or the water supply SW 140 is turned off, the lock release function becomes invalid and the lock release display unit 144 is turned off.

E Hot water supply operation

  When the hot water supply SW 138 is continuously pressed in the press permitted state (unlocked), the hot water solenoid valve 48 is controlled to be in the open state, and hot water is supplied. The hot water solenoid valve 48 is open while the hot water supply SW 138 is continuously pressed. While the hot water supply SW 1318 is being pressed, pressing of the water supply SW 140 is not accepted. That is, the hot water supply SW 138 and the water supply SW 140 perform pre-press priority processing.

F High temperature setting operation

  The high temperature setting SW 126 is heated up to a predetermined high temperature, for example, 93 [° C.] when the power supply control for the hot water heater 42 is pressed in the ON state, by a single operation of the pressing. After the boiling, the hot water temperature is set to an appropriate temperature range set to a high temperature until a predetermined temperature, for example, 90 [° C.]. Then, for example, the temperature is set to 85 [° C.] as the predetermined temperature. During the heating, the high temperature display portion 132 is lit in orange, and the heating completion temperature reaches, for example, 93 [° C.], and the buzzer 166 (FIG. 5) as the notification means is set as a predetermined time at that time. For example, notification is made for 10 seconds, the high temperature display unit 132 is lit in green, the power supply to the hot water heater 42 is shifted to the OFF state, and the high temperature display unit 132 is lit when in the high temperature range (˜90 [° C.]). .

  If the high temperature setting SW 126 is pressed during high temperature boiling, the high temperature boiling operation is stopped. In addition, after the boiling, the power supply to the hot water heater 42 is turned off, and when the high temperature setting SW 126 is pressed again, it is heated as the predetermined temperature to 93 [° C.] which is the above-described high temperature. In this case, even when the temperature of the hot water is less than 93 [° C.] or more than 90 [° C.], the high temperature display portion 132 is lit in orange. When the temperature is less than 90 [° C.] and up to 85 [° C.] after boiling, the normal temperature display unit 130 is lit in green to indicate that the temperature is within the appropriate temperature range of 85 [° C.].

G Energy saving operation

  When the power supply control for the hot water heater 42 is in the OFF state, pressing of the energy saving SW 116 is not accepted. When the energy saving SW 116 is pressed while the power supply to the hot water heater 42 is ON, the energy saving mode is entered, and the energy saving display unit 118 is lit in orange, indicating that the energy saving mode is being executed. When the energy saving SW 116 is pressed in the energy saving mode, the energy saving mode is canceled and the energy saving display unit 118 is turned off.

  When the energy saving mode is being executed and the time is in the energy saving time zone, energy saving is performed, and the energy saving display unit 118 is lit in green.

H Timer / Clock operation

  When the timer / clock SW 120 is pressed in the clock display state, the display becomes a timer display, and the mode shifts to the timer mode. When the timer / clock SW 120 is pressed in the timer mode, the display becomes a clock display. However, when the timer 160 (FIG. 5) is counting down, the countdown is continued.

I Addition operation, subtraction operation, start / stop operation, setting operation

  When the addition SW 112 and the subtraction SW 113 are continuously pressed during the time change mode and when the timer display is switched, the time and the time of the timer are changed.

  When the start / stop SW 122 is pressed during the timer display (standby), the timer 160 (FIG. 5) starts. If the start / stop SW 122 is pressed during the countdown of the timer 160, the countdown is stopped, and the countdown is restarted by pressing again.

  When the setting SW 114 is pressed, the confirmation at the time setting and the start of the energy saving mode and the pressing after the start are ended, and switching according to the pressing is performed.

J Clock display

  The clock display is generated by the power-on state, and the time setting mode is set by continuously pressing the timer / clock SW 120. The clock display is blinking, and in this state, the display is changed by the addition SW 112 or the subtraction SW 113, and the setting is confirmed by pressing the setting SW 114 or elapse of a predetermined time, for example, 10 seconds of no operation. When the addition SW 112 is pressed during the time setting mode, 12: 01 → 12: 02 → 12: 03... And 12: 10 → 12: 20 → 12: 30... 13: 00 → 13: The display is changed from 30 → 14: 00... 15: 00 → 16: 00. When the subtraction SW 113 is pressed during the time setting mode, 11: 59 → 11: 58 → 11: 57... 11: 50 → 11: 40 → 11: 30... 11: 00 → 10: 30 when continuously pressed. → 10:00 ... 9:00 → 8:00.

K timer function

  When the timer / clock SW 120 is pressed, the display unit 100 becomes a timer display. The clock display shows hours and minutes, but the timer display shows minutes and seconds. In this case, the initial setting is 3.00 as described above. The maximum timer time is, for example, 60 [minutes], and the minute display is changed by pressing the addition SW 112 and the subtraction SW 113 during the timer display (standby). When the addition SW 112 is pressed, it becomes 3 → 3.30 → 4 → 4.30 → 5 →... 10 → 11, and thereafter changes continuously up to 60 minutes, which is the same as the clock. When the subtraction SW 113 is pressed, 3 → 2.30 → 2 → 1.30 → 1 → 0.30 → 0. When the start / stop SW 122 is pressed, the timer 160 counts down. Even during the countdown, the minute display can be changed by pressing the addition SW 112 and the subtraction SW 113. When the timer 160 shifts to 0:00, the buzzer 166 is sounded for a predetermined time, for example, 10 seconds.

L Energy saving time setting

  For example, energy saving time can be set up to 2 stages. The time setting method is the same as the time setting. If the first stage or the second stage is set, the energy saving mode is set.

(1) When the energy saving SW 116 is pressed while the clock display state and the power supply control for the hot water heater 42 are ON, “stage 1” and “start” representing the first stage are displayed on the display unit 100. For example, the time display may be “-:-” for the first time, and the current set time for the second and subsequent times.

  When the setting SW 114 is pressed in this state, “Stage 2” and “Start”, “Stage 2” and “End” representing the second stage are displayed on the display unit 100 from the display of “Stage 1” and “End”. ”.

(2) The time can be set by pressing the addition SW 112 or the subtraction SW 113, and the operation is the same as the time setting.

(3) The setting contents are confirmed by pressing the setting SW 114. The state returns to the clock display 10 seconds after the operation is completed or no operation is performed during each operation. If it is desired to cancel (clear) the setting, the setting SW 114 is used to set the stage to be canceled (either start or end), and the addition SW 112 and the subtraction SW 113 are simultaneously pressed. At this time, the display becomes “----”, and the content can be confirmed by pressing the setting SW 114.

  Next, the configuration of the control device will be described with reference to FIG. FIG. 5 is a diagram illustrating a configuration example of the control device. 5, the same parts as those in FIGS. 1, 2, and 4 are denoted by the same reference numerals. Note that the configuration of the control device is merely an example, and is not limited thereto.

  The control device 70 includes a control unit 150 formed of a microcomputer or the like, and the control unit 150 is connected to a display / operation unit 74. The control unit 150 includes a processor 152, an I / O unit 154, a storage unit 156, a RAM (Random Access Memory) 158, a timer 160, and the like, which are connected via a bus 162.

  The processor 152 is configured by a CPU (Central Processing Unit) or an MPU (Micro Processor Unit), and executes an OS (Operating System) and an operation program stored in the storage unit 156. The I / O unit 154 is an input / output interface of the control unit 150. For example, the I / O unit 154 takes in detected temperature information from the cold water sensor 20 and the hot water sensor 54, and the hot water heater 42 connected to the I / O unit 154. The operation control signal is sent to the hot water solenoid valve 48, the cold water solenoid valve 34, the compressor 24, the bypass valve 60, and the like. In addition, it is connected to the display / operation unit 74, takes in each operation input operation described above, and sends a display control signal to the display unit 100 and the like.

  The storage unit 156 is configured by a ROM (Read Only Memory), and functions as a program storage unit that stores an OS to be executed by the processor 152, an operation program of the drinking water supply device 2, an operation program related to a high-temperature water circulation process to be described later, and the like. In addition, various kinds of detected temperature information and the like may be stored. The RAM 158 functions as a working area for processing the operation program. The timer 160 is a time measuring unit and a clock unit. For example, in a cleaning process described later, the timer 160 acquires time information as a cleaning interval timer, an abnormality determination timer, and a cleaning time measurement timer, and is necessary for control. Measure time.

  Further, the control device 150 is connected to a power supply unit 164 that performs power supply control of the drinking water supply device 2 and a buzzer 166 as notification means in the case of abnormal operation.

  Next, FIG. 6 is referred about the circulation of the drinking water in a drinking water supply apparatus regarding the purification process by a high temperature water circulation. FIG. 6 is a diagram illustrating the flow direction of the drinking water 4 during the cleaning process. In FIG. 6, the same parts as those in FIG.

  The drinking water 4 in the cold water tank 8 is cleaned using the hot drinking water 4 in the hot water tank 40. That is, it is circulated between the cold water tank 8 and the hot water tank 40 by utilizing thermal convection caused by the temperature difference between the drinking water 4 in the cold water tank 8 and the drinking water 4 in the hot water tank 40, The temperature of the drinking water 4 is increased to a temperature necessary for cleaning.

  Therefore, in order to raise the temperature of the drinking water 4 in the cold water tank 8, the compressor 24, which is a cooling means for the drinking water 4, is stopped and the power supply control to the hot water heater 42 is turned on, so that the beverage in the hot water tank 40 is turned on. Water 4 is heated. And it heats until the temperature of the drinking water 4 in the warm water tank 40 becomes more than predetermined temperature Th by the temperature detection of the warm water sensor 54. FIG.

  When the bypass valve 60 provided in the bypass pipe 62 is opened and a circulation circuit is formed among the hot water tank 40, the bypass pipe 62, the cold water tank 8, and the water supply pipe 46, the hot drinking water 4 passes through the bypass pipe 62. The cold drinking water 4 in the cold water tank 8 flows into the hot water tank 40 through the water supply pipe 46 (solid arrow A in FIG. 6).

  The chilled water sensor 20 that detects the water temperature in the chilled water tank 8 is installed at a position away from the bypass pipe 62. For example, when the hot water circulates only in a part of the chilled water tank 8 and a short cycle occurs, It is possible to detect abnormal circulation of high-temperature water from the measurement time and detected temperature change.

  The circulation direction of the hot water by heat convection is not limited to the direction of the solid line arrow A in FIG. 6, and as shown by the broken line arrow B, the hot drinking water 4 flows into the cold water tank 8 through the water supply pipe 46. The cold drinking water 4 in the cold water tank 8 may flow into the hot water tank 40 through the bypass pipe 62. Even in such a case, the cleaning process in the cold water tank 8 can be performed.

  The hot water sensor 54 detects the temperature of the drinking water 4 in the hot water tank 40, and when the predetermined temperature Th is, for example, 93 [° C.] or more, the hot water heater 42 is stopped.

  With such a configuration, the drinking water 4 in the cold water tank 8 can be maintained at a temperature suitable for cleaning with a simple configuration, and when the required temperature is not reached even after a predetermined time has elapsed. Since it is notified that there is an abnormality in the cleaning process, a sufficient cleaning process can be performed.

  Next, FIG.7 and FIG.8 is referred about control operation | movement of this drinking water supply apparatus. 7 and 8 are flowcharts showing the processing procedure of the control operation. 7 and 8, A and B are connectors between the flowcharts.

  This processing procedure is a control procedure for purifying the drinking water 4 in the cold water tank 8 according to a predetermined time condition after the initial setting processing after turning on the power. It is executed repeatedly while entering.

  The drinking water supply device 2 is turned on, initial setting of each part, etc., and as an interval timer for counting the cleaning interval by high temperature water circulation, for example, 72 hours is set as an initial value in the timer 160 (step S1) ), And starts counting down (step S2).

  Next, it is determined whether or not the user or the like has set the time in the energy saving mode (step S3). That is, it is a configuration that is performed when the energy saving mode is executed as the execution timing of the high-temperature water circulation treatment. This energy saving mode is a process for saving energy by changing the temperature setting temperature of cold water and hot water in a time zone when the user does not use the drinking water supply device 2 or the amount of use is small, such as at midnight. As described above, since the drinking water supply device 2 cannot be used during the high-temperature water circulation process, if the high-temperature water circulation process is performed in a time zone where the user usage is small, such as the set time of the energy saving mode, the beverage to the user The supply of water 4 is not hindered and convenience is good.

  When the time of energy saving mode is set (YES in step S3), the current time information is, for example, a built-in clock function connected to the timer 160 or the timer / clock SW 120 described above, an external clock function, or the like. To determine whether the current time is the time zone of the energy saving mode (step S4). When the current time is the time zone of the energy saving mode (YES in step S4), the process proceeds to determination of whether or not it is the start time of the energy saving mode (step S5). That is, the cleaning by high-temperature water circulation is performed at the timing when the normal mode is switched to the energy saving mode.

  As described above, the high-temperature water circulation process is performed at the timing of switching to the energy-saving mode because the temperature difference between the set temperature in the normal mode and the set temperature in the high-temperature water circulation process is greater than the set temperature in the energy-saving mode and the set temperature in the high-temperature water mode This is because it is less than the temperature difference. That is, as described above, for the convenience of the user, the drinking water supply device 2 is cleaned during the energy saving mode when the usage amount of the drinking water supply device 2 is small. Since the temperature of the drinking water 4 in the tank 40 is lower than that in the normal mode, the extra heating must be performed accordingly. Therefore, the cleaning process is executed in accordance with the timing of shifting to the energy saving mode. In addition, since a certain amount of time is required for the cleaning process by high-temperature water circulation, the set time of the energy saving mode is prevented from ending during the high-temperature water circulation process.

  If it is the start time of the energy saving mode (YES in step S5), it is determined whether or not the interval timer is up (step S6). As described above, with reference to the timer 160, it is determined whether or not the initial value set in step S1 has elapsed. If the interval timer is up (YES in step S6), high-temperature water circulation processing is performed (step S7), and the process returns to step S3 again.

  If the energy saving time has not been set (NO in step S3), it is determined whether or not the interval timer has expired (step S8). If the time has expired (YES in step S8). ), It is determined whether or not the current time is, for example, 2:00 am as the preset predetermined time P (step S9). That is, the high-temperature water circulation processing when the time setting in the energy saving mode is not performed is configured to be performed at a predetermined time P after the elapse of 3 days (72 hours) set as an initial value. When the current time is the predetermined time P (2 am) (YES in step S9), a high-temperature water circulation process is performed (step S10).

  When the hot water circulation process is completed, as a normal mode, the drinking water 4 in the hot water tank 40 is maintained at the set temperature (step S11), and the drinking water 4 in the cold water tank 8 is maintained at the set temperature ( Step S12).

  If the interval timer is not up (NO in step S8), or if the time is up but the predetermined time P is not reached (NO in step S9), the process proceeds to step S11 as the normal mode.

  Even when the energy saving mode is set (YES in step S3), when it is not in the time zone of the energy saving mode (NO in step S4), or not in the energy saving mode (NO in step S13). The process proceeds to step S11.

  In addition, even in the energy saving time zone (YES in step S4), when high-temperature water circulation is not performed (NO in step S5 or NO in step S6), the energy saving SW 116 is pressed and an energy saving execution input is made. If it is determined (YES in step S13), the mode is shifted to the energy saving mode, the drinking water 4 in the hot water tank 40 is managed at the set temperature in the energy saving mode (step S14), and the drinking water 4 in the cold water tank 8 is changed. The temperature is managed at the set temperature in the energy saving mode (step S15).

  In the temperature management in the normal mode, the hot water tank 40 measures the water temperature with the hot water sensor 54 and operates the hot water heater 42 as necessary so that the temperature set by the display / operation unit 74 is maintained. In the cold water tank 8, the water temperature is measured by the cold water sensor 20 to control the operation of the compressor 24.

  In the energy saving mode, the temperature of the drinking water 4 in the hot water tank 40 is managed at a predetermined temperature lower than that in the normal mode, and the temperature of the drinking water 4 in the cold water tank 8 is managed at a predetermined temperature higher than that in the normal mode. . Thereby, in the temperature management of the drinking water 4, the operation time of the hot water heater 42 and the compressor 24 is shortened to save energy, and the low temperature and high temperature drinking water 4 can be supplied even in the energy saving mode. is there.

  Next, the control shifts to control related to a request for water supply or hot water supply (FIG. 8).

  It is determined whether or not a water supply input has been made in both the normal mode and the energy saving mode (step S16). This determination of the water supply input is made based on, for example, detection of whether or not the water supply SW 140 has been pressed. If the water supply input has been made (YES in step S16), the process proceeds to the determination of whether or not the temperature is a water supply possible temperature (step S17). The water supply possible temperature is a temperature preset in the drinking water supply device 2. For example, when a water supply request is made immediately after the high-temperature water circulation operation, there is a possibility that high-temperature drinking water 4 unexpected by the user may come out of the cold water supply port 38. When the cold water sensor 20 detects that there is, water supply is disabled.

  When the drinking water 4 in the cold water tank 8 is at a water supplyable temperature (YES in step S17), the cold water electromagnetic valve 34 is opened to supply water (step S18), and the count time of the interval timer is set to a predetermined time. Increase Tx (step S19). For example, the predetermined time Tx may be increased according to the number of water supply requests, the amount of drinking water 4 supplied, and the like. That is, the cleaning of the drinking water 4 in the cold water tank 8 is performed in order to prevent the water quality from changing because the low temperature drinking water 4 is not used for a long period of time and stays in the cold water tank 8. As the predetermined time, for example, the cleaning process is performed every 72 hours by high-temperature water circulation. However, if water supply is performed, the drinking water 4 does not stagnate in the cold water tank 8. Therefore, for example, the interval time of the cleaning process may be increased according to the number of water supply requests, the supply amount of the drinking water 4, and the like.

  Moreover, although it is not water supply possible temperature (NO of step S17), for example, when lock release SW142 is pushed down by user operation (YES of step S20), water supply may be enabled.

  After the count time of the interval timer is increased by a predetermined time Tx (step S19), when the water supply input operation is not performed (NO in step S16), the temperature is not the water supply possible temperature (NO in step S17) and the lock is released. If not (NO in step S20), the process proceeds to determination of whether or not a hot water supply input has been made (step S21). In this determination, for example, it is determined by detecting whether or not the hot water supply SW 138 has been pressed by the user.

  In the hot water supply process, it is determined whether or not the lock is released (step S22), hot water is supplied (step S23), and the process returns to step S3 again. Moreover, also when the hot water supply input is not made (NO in step S21) or when the lock is not released (NO in step S22), the process returns to step S3.

  The initial value of the interval timer, the energy saving start time, and the hot water circulation treatment start time other than the energy saving time are examples that are set in advance in the drinking water supply device 2 and are arbitrarily set by the user, Or it can be changed.

  Next, FIG. 9 is referred about the purification process of the drinking water using a high temperature water circulation. FIG. 9 is a flowchart showing a cleaning processing procedure by high-temperature water circulation, which is a subroutine.

  When the cleaning process by the high-temperature water circulation of this drinking water supply device 2 is explained generally, the temperature of the drinking water 4 in the cold water tank 8 is set as the cleaning temperature Tw, for example, as a cleaning time X in a state of 85 ° C. or higher. For example, it is maintained for 30 minutes (steps S113 to S114). In order to maintain the drinking water 4 in the cold water tank 10 at the above temperature, the temperature of the drinking water 4 in the hot water tank 40 on the heating side is maintained at, for example, 93 ° C. or more as the predetermined temperature Th (step S109 to step S110). ).

  Further, as an abnormality determination of the cleaning process, when the temperature of the drinking water 4 in the cold water tank 8 does not reach the cleaning temperature Tw even after the predetermined time Xe has passed, a notification of an abnormality in the high-temperature water circulation is performed (step S1). S101 to S102, steps S112 to S113, S115 to S116).

  Therefore, the hot water circulation operation will be described in the order of each step.

  When the operation of circulating hot water starts, for example, the timer 160 is reset as an abnormality determination timer (step S101) and started (step S102).

  Next, in order to raise the temperature of the drinking water 4 in the cold water tank 8, the compressor 24 which is a cooling means of the drinking water 4 is stopped (step S103), and the power supply control to the warm water heater 42 is turned on (step S103). S104), the drinking water 4 in the hot water tank 40 is heated. Then, by detecting the temperature of the hot water sensor 54, it is determined whether or not the temperature of the drinking water 4 in the hot water tank 40 is, for example, 90 ° C. or more as the predetermined temperature Tb (step S105). This determination of 90 ° C. is the high temperature side preparation temperature for generating thermal convection, and it can also be confirmed whether or not the hot water heater 42 functions as a heating means for the high temperature water circulation process.

  As a result of the determination, when the temperature of the drinking water 4 in the hot water tank 40 is equal to or higher than the predetermined temperature Tb (YES in Step S105), the bypass valve 60 provided in the bypass pipe 62 is opened (Step S106), A circulation circuit is formed. Then, as a circulation timer for measuring the cleaning time X, for example, the timer 160 is reset (step S107) and started (step S108).

  Next, it is determined whether or not the drinking water 4 in the hot water tank 40 is equal to or higher than the predetermined temperature Th based on the temperature detected by the hot water sensor 54 (step S109). If the predetermined temperature Th is not reached (NO in step S109), the hot water heater 42 is operated (step S111).

  For abnormality determination, the timer 160 determines whether, for example, two hours have passed as the predetermined time Xe from the start of the high-temperature water circulation operation (step S102) (step S112). If the predetermined time Xe has not elapsed (NO in step S112), the cold water sensor 20 determines whether the temperature of the drinking water 4 in the cold water tank 8 is equal to or higher than the cleaning temperature Tw (step). S113). If the temperature is not equal to or higher than the cleaning temperature Tw (NO in step S113), the process returns to step S107. If the temperature is equal to or higher than the cleaning temperature Tw (YES in step S113), the cleaning starts from the measurement start of the circulation timer (step S108). The process proceeds to determination of whether or not the time X has elapsed (step S114). Then, steps S109 to S114 are repeated until the drinking water 4 in the cold water tank 8 is at or above the cleaning temperature Tw and the cleaning time X has elapsed.

  By the way, when the temperature of the drinking water 4 in the hot water tank 40 is lower than the predetermined temperature Tb in step S105 (NO in step S105), it is determined whether or not the predetermined time Xe has elapsed by the abnormality determination timer. (Step S115) If the Xe time has not elapsed (NO in Step S115), the process returns to Step S105. If the Xe time has already elapsed (YES in Step S115), the hot water heater 42 is abnormal. It is determined that there is a hot water circulation abnormality notification process (step S116).

  Further, in step S112, when the predetermined time Xe has elapsed by the abnormality determination timer (YES in step S112), that is, even if the Xe time has elapsed since the transition to the high-temperature water circulation operation, the drinking water 4 in the cold water tank 8 is used. On the other hand, even when the condition of the cleaning time X cannot be satisfied at the cleaning temperature Tw, for example, in addition to the abnormality of the bypass pipe 62 and the bypass valve 60, the hot water is in a short cycle state in the cold water tank 8. For example, the abnormality notification in step S116 is performed on the assumption that the hot water circulation abnormality has occurred.

  When it is determined by the timer 160 that the predetermined time X has elapsed for the high-temperature water circulation (YES in step S114), or when abnormality notification processing (step S116) is performed, the bypass provided in the bypass pipe 62 The valve 60 is closed (step S117). Then, an initial value is set in the interval timer (step S118), countdown is started (step S119), and the hot water circulation operation is terminated.

  With such a configuration, the drinking water 4 in the cold water tank 8 can be maintained at a temperature suitable for cleaning with a simple configuration, and if it does not reach the required temperature even after a predetermined time has passed, it is cleaned. Since it is notified that there is an abnormality in the purification process, a sufficient cleaning process can be performed.

[Second Embodiment]

  Next, FIG. 10 is referred about 2nd Embodiment. FIG. 10 is a diagram illustrating a configuration around the cold water tank of the drinking water supply apparatus according to the second embodiment and a configuration inside the panel unit formed in the housing. 10, the same parts as those in FIGS. 1 and 3 are denoted by the same reference numerals, and description thereof is omitted. In addition, the structure of the water supply part in the cold water tank shown in FIG. 10 is an example, and is not limited to this.

  In this embodiment, the supply of the drinking water 4 from the gallon bottle 6 is restricted according to the level of the drinking water 4 in the cold water tank 8 and the drinking water 4 stored in the cold water tank 8 It is the structure provided with the separator float which interrupts | blocks the contact with the drinking water 4 in the gallon bottle 6. FIG.

  A lid 80 is installed on the inner upper side of the cold water tank 8 on the outer peripheral side of the support wall that supports the gallon bottle 6. The above-described protrusion 68 is formed at the center of the lid portion 80. The protrusion 68 is, for example, a columnar shape, and an intake port 82 for the drinking water 4 is formed on the upper side surface thereof. Further, the lower end of the protrusion 68 is opened to the cold water tank 8 and constitutes a drinking water intake portion 84. With such a configuration, the drinking water 4 that has flowed out of the gallon bottle 6 enters the intake port portion 82 of the protrusion 68 and is supplied from the drinking water intake portion 84 into the cold water tank 8.

  On the lower side of this drinking water intake portion 84, the means for limiting the amount of inflow of drinking water 4 into the cold water tank 8 and the contact between the drinking water 4 in the gallon bottle 6 and the drinking water 4 in the cold water tank 8 are cut off. A separator float 86 is installed as a blocking means. The separator float 86 is installed inside the float cover 88 and floats and sinks depending on the level of the drinking water 4 in the cold water tank 8. For example, the float cover 88 has a lattice structure at its circumference and bottom, and the drinking water 4 flows into the cold water tank 8 from between the lattices. The float cover 88 is attached to the bottom of the lid portion 80, and the lid portion 80 and the float cover 88 can be attached and detached by a lock mechanism 90. In addition, a hole 94 for inserting the shaft portion 92 of the separator float 86 is provided in the bottom center of the float cover 88.

  Thereby, when the water level of the drinking water (cold water) 4 in the cold water tank 8 rises, the separator float 86 is pushed up, and when the upper part comes into contact with the drinking water intake part 84 of the lid part 80, the gallon bottle 6 Supply of drinking water 4 is stopped. When the water level of the drinking water 4 in the cold water tank 8 drops and the upper surface of the separator float 86 moves away from the drinking water intake portion 84 of the lid portion 80, for example, the air taken in from the air intake 14 is It enters the gallon bottle 6 from the water intake part 84. Due to the intrusion of air, drinking water 4 is supplied from the gallon bottle 6 to the cold water tank 8. When the water level in the cold water tank 8 rises and the separator float 86 closes the drinking water intake 84, the inflow of the drinking water 4 from the gallon bottle 6 is stopped again. Thereby, the drinking water 4 in the cold water tank 8 and the drinking water 4 in the gallon bottle 6 can be blocked. That is, contact between the drinking water 4 enclosed in the gallon bottle 6 and the drinking water 4 in contact with the outside air in the cold water tank 8 can be prevented.

  Moreover, the separation plate 16 that separates the drinking water 4 in the cold water tank 8 into upper and lower layers is formed in a concave shape by providing a step at the center. By forming in this way, contact with the float cover 88 provided with the separator float 86 can be avoided, and the installation height of the end of the separation plate 16 is higher than that of the evaporator 18 which is a cooling means. Therefore, the cold water and the hot water in the cold water tank 8 can be separated.

  Examples of advantageous effects resulting from the separation of the drinking water 4 in the cold water tank 8 and the drinking water 4 in the gallon bottle 6 include the following.

  (1) It is possible to prevent the water temperature in the gallon bottle 6 from increasing as the temperature of the drinking water 4 in the cold water tank 8 rises in the purification process by the high-temperature water circulation process described later, and bacteria in the gallon bottle 6 Etc. can be prevented from breeding.

  (2) The separator float 86 as the blocking means can prevent the temperature of the air in the gallon bottle 6 from increasing as the temperature of the drinking water 4 in the gallon bottle 6 increases. That is, it is possible to prevent the temperature of the drinking water 4 in the gallon bottle 6 from rising and the internal air from expanding, and the drinking water 4 corresponding to the expanded volume from flowing into the cold water tank 8 side. it can. Thereby, for example, when high-temperature water circulation is executed, low-temperature drinking water 4 flows into the cold water tank 8 from the gallon bottle 6 side to prevent the temperature of the drinking water 4 from rising, and continues to heat excessively for a long time.
