[First embodiment]
FIG. 1 shows a water server 2 according to the first embodiment. The configuration shown in FIG. 1 is an example, and the present disclosure is not limited to such a configuration.

This water server 2 has a power supply unit 4, and operates normally when AC power is supplied (hereinafter referred to as "normal mode"), when AC power supply fails (hereinafter simply referred to as "power failure"), and operates by power supply from battery 6. (hereinafter referred to as "blackout mode") is possible. This power supply unit 4 is an example of the power supply device of the present disclosure. Normal mode includes all operations including hot water generation and its injection, cold water generation and its injection, based on the AC power supply. On the other hand, the power failure mode includes an operation in which at least cold water or the like can be injected while suppressing consumption of the battery 6 based on battery power supply.

The power supply unit 4 can be powered by both the battery 6 and the AC source 8 . For the battery 6, for example, a series circuit of eight AA batteries provides an output voltage of 12 [V]. The AC source 8 is, for example, a commercial AC power supply of AC 100 [V].

The activation button 10 is an example of a activation switch for activation by battery power supply in the event of a power failure. The power supply unit 4 includes a DC stabilization unit 12 , an AC detection unit 14 , a battery power supply holding unit 16 and a battery power supply canceling unit 18 .

When AC power is supplied, the DC stabilization unit 12 operates with the AC power supply to generate a DC stabilized output. The DC stabilizing section 12 includes a full-wave rectifying circuit, a smoothing circuit, a stabilizing circuit, etc., and generates a DC stabilized output by full-wave rectification of AC, smoothing and stabilization thereof. Therefore, during AC power supply, the power supply section 4 constitutes a DC stabilized power supply with the DC stabilization section 12 , and this DC stabilization output is supplied to the control section 20 . At this time, the normal mode is entered.

The AC detector 14 detects the presence or absence of power supply from the AC source 8 , and this detection output is applied to the controller 20 . This AC detection output is used for power supply switching control from the sleep state to the normal mode, control for disabling the activation button 10 during AC power supply, and the like.

After power failure of the AC source 8, the battery power supply holding unit 16 starts activation by the start button 10 from the rest state, and holds the battery power supply. When this battery power supply is maintained, it becomes a power failure mode. On the other hand, the battery power supply canceling unit 18 receives the battery power supply canceling signal Soff from the control unit 20 and cancels the battery power supply. In the event of a power failure, the power supply unit 4 and the control unit 20 are put into a resting state before the activation by the activation button 10 and after the battery power supply is terminated.

The control unit 20 including the power supply unit 4 is an example of the control device of the present disclosure. This control unit 20 is configured by, for example, a computer. During AC power supply, it receives the DC output from the DC stabilization unit 12 and executes the normal mode. When the AC power source 8 is out of power, the DC output from the battery power supply is received from the power supply unit 4 from the start of activation of the start button 10, and the power failure mode is executed.
In this power failure mode, the control unit 20 monitors the elapsed time Mt from the start of activation of the activation button 10, and outputs the battery power supply termination signal Soff after the elapsed time Mt reaches a threshold value Mth, for example, 60 [seconds]. In this case, if the water pouring operation is in progress when the elapsed time Mt reaches the threshold value Mth, the water pouring function of the water server 2 is given priority, so the measurement of the elapsed time Mt is stopped or the elapsed time Mt is reset, and the water pouring operation is performed. is terminated, the battery power supply canceling signal Soff is output to cancel the battery power supply.

After canceling the power failure mode, if the battery 6 has power supply capability, the power failure mode can be repeatedly executed by re-operating the start button 10 .

In this way, the water server 2 has a power outage pause unit 21 that pauses part of the operation. This power failure suspension unit 21 is means for reducing the load on the battery power supply in the power failure mode. This power outage suspending unit 21 includes a direct current stabilizing unit 12, an alternating current detecting unit 14, and a large current load 22 such as a cooling device and a hot water heater. Therefore, in the power failure mode, water injection, information presentation, etc. are possible with the minimum necessary load including water injection and information presentation together with the control part 20 except for the power failure pause part 21, and consumption of the battery 6 is suppressed.

In this water server 2, the electromagnetic valve section 24, the information presentation section 25 and the operation section 26 receive the DC stabilization output or the battery power supply output from the power supply section 4, operate under the control of the control section 20, and operate in the normal mode or power failure mode. Operation corresponding to is possible. The solenoid valve portion 24 is an example of a water injection operation portion. Under the control of the control unit 20, the solenoid valve unit 24 can be opened for hot water or cold water injection in the normal mode, and can be opened for water injection in the power failure mode. The information presenting unit 25 can present information corresponding to the normal mode or power failure mode. The operation unit 26 can be operated in a normal mode or a power failure mode.

<Control Function of Control Unit 20>
A of FIG. 2 shows an example of the control function of the control unit 20 . The control of the control unit 20 includes normal mode control 20-1, power failure determination 20-2, power failure mode startup control 20-3, threshold value Mth setting 20-4 for elapsed time Mt, and monitoring of elapsed time Mt 20. -5, water injection operation monitoring 20-6, power failure mode release control 20-7, information presentation control 20-8, and the like.

Normal Mode Control 20 - 1 : The control unit 20 executes power supply control for supplying power to the entire system of the water server 2 when power is supplied from the AC source 8 . The control unit 20 acquires the AC detection output of the AC detection unit 14 and recognizes the state of power supply from the AC source 8 . When power is supplied from the AC source 8 , power is supplied to the DC stabilizer 12 , the control unit 20 and the large current load 22 . At this time, the activation button 10 and the battery power supply holding unit 16 are disabled, so the battery power supply cancellation state of the battery power supply canceling unit 18 is maintained.

Determination of power failure 20-2: The control unit 20 acquires detection output information from the AC detection unit 14 and determines power failure of the AC source 8 . At the time of power failure, power supply to the control unit 20 is canceled, and as a result, invalidation of the start button 10 and the battery power supply holding unit 16 is also canceled.

Power failure mode activation control 20-3: When the power failure of the AC source 8 occurs, the battery power supply holding unit 16 retains the battery power supply from the time the activation button 10 is operated, and shifts to this power failure mode. As a result, the control unit 20 shifts to the power failure mode with the operation of the start button 10 as a trigger. In other words, based on the operation of the activation button 10, the power supply unit 4 generates battery output by battery power supply, and the control unit 20 operates by battery power supply. At this time, the power failure pause unit 21 transitions to the pause state, and unlike the normal mode, the power failure mode suppresses consumption of the battery 6 .

Setting 20-4 of Threshold Mth of Elapsed Time Mt: The controller 20 measures the elapsed time Mt from the start of activation of the activation button 10. FIG. A threshold value Mth corresponding to a certain period of time during which no water injection operation is performed is set for the elapsed time Mt. The setting of the threshold Mth includes the setting of the threshold Mth from the start of activation and the setting of the threshold Mth from the end of the water pouring operation.

Monitoring of elapsed time Mt 20-5: The control unit 20 monitors the elapsed time Mt and monitors whether or not the elapsed time Mt reaches the threshold value Mth.

Water injection operation monitoring 20-6: The control unit 20 acquires operation information of the solenoid valve unit 24 and monitors the water injection operation.

Power failure mode release control 20-7: The control unit 20 executes power failure mode release control when the AC source 8 is restored during the power failure mode.

Information presentation control 20-8: The control unit 20 presents information on the water pouring operation to the information presentation unit 25 in the normal mode or the power failure mode.

<Mode switching>
B of FIG. 2 shows an example of mode switching of the water server 2 .
During power supply from the AC source 8, when the AC detection unit 14 detects AC, the control unit 20 gives priority to the normal mode and activation by the activation button 10 does not occur.

When the AC power source 8 fails, the control unit 20 permits a shift from the normal mode to the power failure mode, and accepts the activation operation by the activation button 10 . When the activation button 10 is operated, the power supply unit 4 and the control unit 20 shift from the sleep state to the power failure mode. This power failure mode is an operation mode after startup and before output of the battery power supply cancellation signal Soff, and is a battery power supply mode.

After the battery power supply is canceled by the battery power supply cancellation signal Soff, the power supply unit 4 and the control unit 20 transition to the power failure mode canceled state before the activation button 10 is operated.

During power supply from the AC source 8 or recovery from a power failure, the control unit 20 maintains the battery power supply in the canceled state by the battery power supply cancellation function of the battery power supply cancellation unit 18 based on the AC detection of the AC detection unit 14 .

The control unit 20 monitors the water injection operation, and after the water injection operation ends, outputs the battery power supply cancellation signal Soff even if the elapsed time Mt is within the threshold value Mth, and shifts to the power failure mode cancellation state.

In power supply control, processes such as process procedure 1-1 (FIG. 3) and process procedure 1-2 (FIG. 4) for realizing the above control function can be executed.

<Power supply control processing procedure 1-1>
FIG. 3 shows an example of power supply control processing procedure 1-1. This power supply control is an example of the water supply method of the present disclosure or its program. Although S indicates a step and the number attached to S indicates an example of the order of steps, the present disclosure is not limited to this.

This power supply control includes an AC detection step (S101), an AC power supply control step (S102), a normal mode control step (S103), a power failure mode cancellation step (S104), a startup step (S105), and a power failure mode control step (S106). , an elapsed time monitoring step (S107), and a water pouring operation monitoring step (S108).

The AC detection unit 14 detects the presence or absence of AC power supply (S101), and when AC power supply is in effect (YES in S101), power supply control of the water server 2 by AC power supply is executed (S102), and control in the normal mode is performed. (S103).

If the start button 10 is operated (YES in S105) at the time of power failure of the AC source 8 (NO in S101), this operation triggers battery power supply. If the activation button 10 is not operated (NO in S105), the process returns to S101. In this case, the power failure mode canceled state is maintained.

Triggered by the activation operation by the activation button 10, the power failure mode is entered (S106), the elapsed time Mt of the battery power supply is being monitored (S107), and the water injection operation is monitored (S108). If there is (YES in S107), the power failure mode (battery feeding) is maintained (S106).

If the elapsed time Mt of battery power supply is within the threshold Mth and there is a water injection operation, even if the elapsed time Mt exceeds the threshold Mth (NO in S107), the power failure mode (battery power supply) is maintained until the water injection operation ends. (S106). Then, after the water pouring operation is completed (YES in S108), the control unit 20 outputs the battery power supply cancellation signal Soff, and the battery power supply is cancelled.

<Power supply control procedure 1-2>
FIG. 4 shows an example of power supply control processing procedure 1-2. This power supply control is an example of the water supply method of the present disclosure or its program. Although S indicates a step and the number attached to S indicates an example of the order of steps, the present disclosure is not limited to this.

This power supply control includes an AC detection step (S111), an AC power supply control step (S112), a normal mode control step (S113), a power failure mode cancellation step (S114), a startup step (S115), and a power failure mode control step (S116). , a water pouring operation monitoring step (S117), an elapsed time Mt measuring step (S118), an elapsed time Mt monitoring step (S119), an elapsed time Mt initialization step (S120), and a water pouring operation end monitoring step (S121). including processing such as

The AC detection unit 14 detects the presence or absence of AC power supply (S111), and when AC power supply is in effect (YES in S111), power supply control of the water server 2 by AC power supply is executed (S112), and control in the normal mode is performed. (S113).

If the start button 10 is operated (YES in S115) when the AC source 8 fails (NO in S111), this operation triggers battery power supply. If the activation button 10 is not operated (NO in S115), the process returns to S111.

When there is an activation operation by the activation button 10 (YES in S115), the power failure mode is entered (S116), and water pouring operation is monitored to determine whether there is no water pouring operation (S117). If there is no water pouring operation (YES in S117), the elapsed time Mt of battery power supply is measured (S118). To monitor the elapsed time Mt, it is determined whether the elapsed time Mt is within the threshold value Mth (S119). If the elapsed time Mt is within the threshold value Mth (YES in S119), the power failure mode (battery feeding) is maintained (S116).

If there is a water pouring operation (NO in S117), the measurement of the elapsed time Mt is stopped, and the measured elapsed time Mt is cleared (Mt=0) (S120). As end monitoring of the water pouring operation, it is determined whether the water pouring operation has ended (S121). If the water injection operation ends (YES in S121), the power failure mode (battery power supply) is maintained (S116). If the water pouring operation continues (NO in S121), it continues to monitor whether the water pouring operation has ended.

When the battery power supply elapsed time Mt exceeds the threshold value Mth (NO in S119), the battery power supply (power failure mode) is canceled (S114), and the process returns to S111. That is, the battery power supply cancellation signal Soff is output to cancel the battery power supply.

<Relationship between elapsed time Mt, threshold Mth, and water injection operation>
FIG. 5 shows the relationship between elapsed time Mt, threshold Mth, and water pouring operation.
As shown in FIG. 5A, time t0 is, for example, the start-up time. The time from time t0 to time t2 is the threshold Mth. As shown in FIG. 5B, when water injection is started at time t1 before the elapsed time Mt of battery power supply reaches the threshold Mth, even if the elapsed time Mt reaches the threshold Mth, unless the water injection operation is stopped. , its water-filling action is maintained. In this example, the water injection operation continues until time t3 when the threshold Mth is exceeded. That is, when water is injected before the elapsed time Mt reaches the threshold value Mth, the battery power supply cancellation signal Soff is not output as long as this water injection continues. In this case, the water pouring operation substantially extends the threshold Mth as indicated by the dashed line.

As shown in FIG. 5C, time t10 is the start-up time. The time from time t10 to time t12 is the threshold Mth. As shown in D of FIG. 5, water injection is started at time t11 before the elapsed time Mt of battery power supply reaches the threshold value Mth, and the water injection operation continues until time t13.

In this case, the elapsed time Mt is cleared (Mt=0) at the start time t11 of the water pouring operation, and the threshold Mth is also canceled at the start time t11. That is, the previous threshold Mth should be continued until time t12, but is canceled at time t11, resulting in a shorter time for the threshold Mth.

Then, when the water pouring operation ends at time t13, this time t13 becomes a new restart time for measuring the elapsed time Mt. At time t13, the threshold Mth from time t13 to time t14 is set as a new threshold Mth. That is, even if the previous threshold Mth is canceled at time t11, a new threshold Mth is set in preparation for the next water pouring operation.

In this way, since the threshold Mth is updated after the previous threshold Mth is canceled, the waiting period for re-filling water after water filling can be automatically set, and the re-operation of the start button 10 can be omitted.

<Effects of the first embodiment>
According to this first embodiment, one of the following effects can be obtained.
(1) In the event of a power outage, the water server 2 can be started by operating the start button 10 to start battery power supply.

(2) Since the suspension unit 21 suspends during a power failure, consumption of the battery 6 can be suppressed.

(3) The solenoid valve portion 24 can be operated in the battery power supply mode, and water can be injected by operating the solenoid valve portion 24 with battery power supply.

(4) The water server 2 can be used by battery power supply not only due to bad weather, but also due to power failure due to maintenance of the power supply system, etc., or power supply stoppage due to moving the water server 2 to a place where there is no outlet.

(5) When battery power is supplied, the elapsed time Mt is monitored from the start of activation, and the battery power supply is maintained for a certain period of time.

(6) During battery power supply, if the water pouring operation is in progress when the elapsed time Mt from the start of activation exceeds the threshold value Mth, the power failure mode is maintained, so the water pouring operation can be continued until the water pouring ends.

(7) When power is supplied from the battery, the control unit 20 monitors the elapsed time Mt in which there is no water injection operation (non-operating state), and the water injection operation is performed at a threshold value Mth (continuous fixed time) set for this elapsed time Mt. If there is no battery, the battery power supply is canceled, so the consumption of the battery 6 can be suppressed, and the battery life (usage time of the battery 6) can be extended.

<Processing procedure for power supply control>
FIG. 12 shows the processing procedure of power supply control. This power supply control includes an AC detection step (S201), a control step (S202) of the power supply unit 4, a normal mode control step (S203), a battery power supply cancellation signal Soff output step (S204), and a battery power supply cancellation step (S205). ), starting step (S206), power failure mode control step (S207), hot water button 80 pressing step (S208), cold water button 79 pressing step (S209), elapsed time Mt measuring step (S210), elapsed time Mt monitoring step (S211), elapsed time Mt initialization step (S212, S216), hot water solenoid valve 65 opening step (S213), hot water button 80 releasing step (S214), hot water solenoid valve 65 closing step (S215), the process of opening the cold water solenoid valve 64 (S217), the process of releasing the cold water button 79 (S218), and the process of closing the cold water solenoid valve 64 (S219).

The AC detector 14 detects the presence or absence of AC power supply (S201). Power supply control for the current load 22 (FIG. 1) is executed (S202). In this power supply control, control in the normal mode is performed (S203).

In this normal mode, a battery power supply cancellation signal Soff is output from the control unit 20 (S204), and the battery power supply is controlled to be in a cancellation state (S205). At this time, temperature control of cold water temperature and hot water temperature is being executed, and the temperature of cold water and hot water is optimized.

In this normal mode, when the cold water button 79 is pressed, the cold water electromagnetic valve 64 is opened and cold water is injected from the water inlet 36 . In the power failure mode, when the cold water button 79 is pressed, the cold water solenoid valve 64 is similarly operated to open and water is injected from the water injection port 36 . Further, when the hot water button 80 is pressed, the hot water solenoid valve 65 is operated in an open state, and hot water is poured from the hot water pouring port 38 . In the power failure mode, when the hot water button 80 is pressed, the hot water solenoid valve 65 is similarly operated to open and water is poured from the pouring port 38 .

If the start button 10 is operated (YES in S206) when the AC source 8 fails (NO in S201), this operation triggers battery power supply. If the activation button 10 is not operated (NO in S206), the process returns to S201.

When there is an activation operation by the activation button 10 (YES in S206), power failure mode control is performed (S207), and pressing of the hot water button 80 and the cold water button 79 is monitored (S208, S209). If the hot water button 80 or the cold water button 79 is not pressed (NO in S208, NO in S209), the elapsed time Mt is measured (S210). If the elapsed time Mt is within the threshold value Mth (YES in S211), the power failure mode control is maintained (S207). When the elapsed time Mt exceeds the threshold Mth (NO in S211), the process proceeds to S204.

If the hot water button 80 is operated and turned ON during measurement of the elapsed time Mt (YES in S208), measurement of the elapsed time Mt is stopped, the elapsed time Mt is cleared (Mt=0) (S212), and the controller 20, the hot water electromagnetic valve 65 is opened (S213). This open valve is maintained as long as the hot water button 80 is pressed, and in the power failure mode, the water stored in the hot water tank 104 is poured from the pouring port 38 . Then, if the hot water button 80 is turned off (YES in S214), the hot water solenoid valve 65 is closed under the control of the controller 20 (S215). At this time, the pouring of molten metal from the pouring port 38 is stopped.

If the cold water button 79 is operated and turned ON during measurement of the elapsed time Mt (YES in S209), measurement of the elapsed time Mt is stopped, the elapsed time Mt is cleared (Mt=0) (S216), and the control unit 20, the cold water electromagnetic valve 64 is opened (S217). This valve opening is maintained as long as the cold water button 79 is pressed, and in the power failure mode, the water stored in the cold water tank 102 is injected from the water injection port 36 . Then, if the cold water button 79 is turned off (YES in S218), the cold water electromagnetic valve 64 is closed under the control of the control unit 20 (S219). At this time, water injection from the water injection port 36 is stopped.

Therefore, the control unit 20 measures the elapsed time Mt from the start of activation, and sets a threshold value Mth representing a continuous fixed time with respect to the elapsed time Mt. reaches the threshold value Mth, the battery power supply cancellation signal Soff is output, and if the water injection operation is in progress when the elapsed time Mt reaches the threshold value Mth, the battery power supply cancellation signal is sent to the power supply unit 4 after the water injection operation is completed. Output Soff.

In addition, the control unit 20 measures the elapsed time Mt from the end of the water pouring operation, and sets a threshold value Mth representing a certain period of time that has continued with respect to the elapsed time Mt. After the time Mt reaches the threshold value Mth, the battery power supply cancellation signal Soff is output, and if the water injection operation is being performed when the elapsed time Mt reaches the threshold value Mth, the battery power supply is supplied to the power supply unit 4 after the water injection operation ends. A release signal Soff is output.

After releasing the lock by pressing the lock/release button 84 for a short time, the hot water button 80 is continuously pressed for an arbitrary time. In this operation C, hot water pouring is possible in the normal mode, and water pouring is possible in the blackout mode.

In this operation C, in the power failure mode, as shown in FIG. 15, it is determined whether the lock/release button 84 is pressed for a short time (S401). It is determined whether the button 80 is ON (S402). If the hot water button 80 is ON (YES in S402), the hot water solenoid valve 65 is opened under the control of the controller 20 (S403). This allows water to be poured from the hot water tank 104 . This valve open state is monitored by the controller 20 to determine whether the hot water button 80 is OFF (S404). If the hot water button 80 is OFF (NO in S402), the hot water electromagnetic valve 65 is closed to stop water injection.

A cold water lamp 68, a weak cooling lamp 70, a hot water lamp 72, a high temperature lamp 74, an energy saving lamp 75, a lock lamp 76, and the like are used to display information in the normal mode or power failure mode.

In the normal mode, the cold water lamp 68 lights to indicate cold water, the weak cold lamp 70 lights to indicate weak cold, the warm water lamp 72 lights to indicate hot water, the high temperature lamp 74 lights to indicate high temperature, and the energy saving lamp 75 lights to indicate energy saving. present any of the Also, the lock lamp 76 presents an unlock display or a lock display depending on the lighting mode.

In blackout mode, cold water lamp 68, hot water lamp 72 and lock lamp 76 are used. The cold water lamp 68 and the hot water lamp 72 are controlled by the control unit 20 to select the lighting mode, and when water can be poured, a water pouring possible indication is presented.

In the power failure mode, for example, as shown in FIG. 16B, the chilled water lamp 68 indicates that water can be poured in green when the cold water is at an appropriate temperature, and in orange when the temperature is not appropriate. Moreover, unlike the initial state, the hot water lamp 72 indicates that water can be poured, for example, as shown in FIG. The lock lamp 76 is also used in the power failure mode, and is controlled by the control unit 20, for example, as shown in D of FIG. , to present a locked or unlocked indication.

<Water injection control and water injection display control in blackout mode>
Water injection control and water injection display control include a temperature detection process, an information presentation process, a water injection control process, and the like. These functions are executed through the information processing of the control unit 20 .

In the temperature detection step, the control unit 20 acquires temperature information from the cold water temperature sensor 87 that detects the temperature of the water stored in the cold water tank 102 .

In the information presenting step, the information presenting unit 25 presents at least cold water display or pouring possible display under the control of the control unit 20 .

In the water injection control step, if the detected temperature of the stored water is below a predetermined temperature, cold water display is presented to the information presentation unit 25 and the control unit 20 permits water injection. Cancel the cold water display and prohibit water injection.

Furthermore, in the power failure mode, the power supply to the hot water heater 62 may be stopped under the control of the control unit 20, and the information display unit 25 may display a display indicating that water can be poured in place of the display of hot water.

<Effects of Second Embodiment>
According to the second embodiment, one of the following effects can be obtained.
(1) During a power outage, by continuously pressing the cold water button 79, the water stored in the cold water tank 102 can be supplied, and by continuously pressing the hot water button 80, the water stored in the hot water tank 104 can be supplied. Cold or hot water can be injected if the residual water is immediately after a power failure.

(2) As time elapses after the power failure, the temperature of the water stored in the cold water tank 102 becomes equal to the temperature of the raw water in the water container 100 according to demand, and the temperature of the water stored in the hot water tank 104 also becomes the same. However, it is possible to prevent the mixing of normal temperature water and hot water by prohibiting the water supply from the hot water tank 104 .

(3) In the power outage mode, the water pouring display is different from that in the normal mode, and information representing the water pouring state during power outage is presented, so the convenience of the water server 2 can be enhanced.

FIG. 17 shows an example of the AC detector 14 according to the first embodiment. In FIG. 17, the same parts as in FIGS. 1 and 8 are denoted by the same reference numerals.

This AC detector 14 detects whether power is being supplied or a power outage based on periodic voltage changes in the AC voltage of the AC source 8 . A full-wave rectifier 138 provided in the AC detector 14 outputs a full-wave rectified voltage by full-wave rectification of the AC from the AC source 8 . The voltage level of this full-wave rectified voltage changes every half cycle.

This full-wave rectified voltage causes a current adjusted by resistors 140 and 142 to flow through a light emitting element 146 to emit light. This light emission changes depending on the voltage level of the full-wave rectified voltage. That is, it emits light periodically.

The light receiving element 148 of the photocoupler 144 receives intermittent light from the light emitting element 146 and repeats ON/OFF. Since the applied voltage from the signal power supply 150 is applied to the collector of the light receiving element 148 via the resistor 152, a pulse signal having the applied voltage of the signal power supply 150 as a peak is obtained. This pulse signal is an AC detection signal and is applied to the controller 20 via the resistor 154 . That is, when the AC detection signal is canceled, it indicates that the AC source 8 has failed.

<Effect of Example 1>
According to the first embodiment, one of the following effects can be obtained.
(1) According to such an AC detection unit 14, it is possible to instantaneously detect when the AC source 8 is powered or when a power failure occurs.

(2) By using this AC detection signal, when power supply is restored from a power failure, the control unit 20 can generate a battery power supply cancellation signal Soff to cancel battery power supply and control the power supply unit 4 to the normal mode. can.

The battery power supply holding unit 16 holds battery power supply by the start button 10, and the battery power supply canceling unit 18 receives a battery power supply canceling signal from the control unit 20. Soff cancels the battery power supply.

<Maintenance of battery power supply>
The battery power supply holding section 16 comprises a switch circuit consisting of a self-holding relay 156 and transistors 158 and 160 . Diode 165 is an example of a back electromotive force absorption element. When the start button 10 is pressed and closed when the AC power source 8 fails, the battery voltage is applied from the battery 6 to the relay coil 162 of the relay 156, and the contact 164 of the relay 156 is closed, so that the transistors 158 and 160 are turned on. becomes. That is, the start of power failure mode.

The ON state of transistors 158 and 160 magnetizes relay coil 162 . Even if the contact 164 is closed and the activation button 10 is turned off, the battery voltage is applied to the relay coil 162 from the battery 6 through the closed contact 164, and the magnetization of the relay coil 162 is maintained. Therefore, the battery power supply is maintained, and the battery voltage instead of the DC stabilized voltage is applied to the control unit 20 through the isolation diode 50-2.

<Cancel battery power supply>
