When the tableware disinfection storage 10 is operated independently by removing the connection line 14, the operation of the storage / disinfection storage 10 for the second and subsequent tableware disinfection storages 10 is also performed.
The delay timer 42 starts counting by the start operation of the stop switch 38, and the operation is automatically started when the count ends.

When the operation / stop switch 38 is stopped in each of the tableware disinfection storages 10, if the storage 10 is in operation, the operation is stopped, and all the subsequent tableware disinfection storages are stopped. Reference numeral 10 is set so that the standby state is released. When the operation / stop switch 38 of the tableware disinfection storage 10 in the standby state is stopped (re-operated),
The standby state of the storage 10 is released so that the operation is not started even if the operation end signal from the previous tableware disinfection storage 10 is input, and the standby state of all the subsequent tableware sterilization storages 10 is maintained. Is set to cancel. In addition, each tableware disinfection storage 10 is set not to receive any signal other than the signal by operating the operation / stop switch 38 during the operation, and the operator manually operates the operation / stop switch 38.
Unless the operation is performed, the operation is performed to the end.

Each tableware disinfection storage 10 of the embodiment has a state before operation, an operation standby state, a state in which the delay timer 42 is counting, an operation state, and an operation end state.
The processing after the recovery from the power failure is appropriately set according to each state. That is, in the state before the operation, the operation standby state, and the operation end state, the state is maintained after the recovery from the power failure. Also, in the counting state of the delay timer 42, after the recovery from the power failure, the count of the delay timer 42 is reset and restarted from the beginning, and in the operating state, after the recovery from the power failure, the count of the operation timer is reset and the counting is started from the beginning. Is set to restart. This prevents a plurality of tableware disinfection storages 10 from being operated at the same time after recovery from the power failure.

When a power failure occurs, a power failure display is displayed on the display unit of the operation panel 40 so that the operator can be notified of the power failure. Whether the above-described power failure processing operation is performed without displaying the power failure or only the fact that there is a power failure is displayed on the operation panel 40 while all the tableware disinfection holding boxes 10 are stopped at the time of the power failure. Is configured to be selectable.

[0019]

Next, the operation of the method for operating the dishwashing storage according to the above-described embodiment will be described. First, a case will be described in which, for example, in a food and beverage facility in which the tableware disinfection storage 10 is used, a power supply capacity sufficient to operate a plurality of tableware disinfection storages 10 at the same time cannot be secured and only one unit can be operated.

When the start / stop switch 38 of the first tableware disinfection storage 10 connected to the power supply equipment 15 is started, the control device 12 of the storage 10 controls all the tableware disinfection storages 10. The standby signal is output, the standby state is established, and the state is displayed on the corresponding operation panel 40. In the first tableware disinfection storage 10,
Since the delay time of the delay timer 42 is set to zero, the operation is started simultaneously with the start operation of the operation / stop switch 38. The operation start signal output from the first dishwashing storage 10 is input to the second dishwashing storage 10, and the second dishwashing storage 10 is in a standby state, so that the delay timer 42 Starts counting.

In the first tableware disinfection storage 10, the operation of the blower 30 and the heater 32 is controlled, and the tableware stored in the storage section 20 is heated by hot air circulated forcibly to disinfect and dry. Is done. When the preset operation time elapses, the operation of the first dishwashing storage 10 is automatically stopped, and an operation end signal is output to the second dishwashing storage 10, In the second tableware disinfection storage 10 to which the signal has been input, the operation is automatically started. At this time, the operation start signal output from the second tableware disinfection storage 10 is input to the third tableware sterilization storage 10 in the standby state, as described above, and the third tableware disinfection storage is performed. The delay timer 42 of the storage 10 starts counting. If the first tableware disinfection storage 10 is operating normally, an operation end signal is input before the end of the count of the delay timer 42 of the second tableware disinfection storage 10, so that two The dishwashing storages 10, 10 are not operated at the same time.

When the operation of the second dishwashing storage 10 is completed, the operation of the third dishwashing storage 10 is automatically started. Regarding the following tableware disinfection storage 10 as well, when the operation of the previous tableware sterilization storage 10 is completed, the operation of the next tableware sterilization storage 10 is automatically started. The tableware stored in all the tableware disinfection storages 10 is disinfected and dried by repeating the above steps sequentially. That is, even when a plurality of dishwashing storages 10 cannot be operated at the same time, the operator only needs to operate the operation / stop switch 38 of the first dishwashing storage 10, and all the dishwashing storages are required. 10
Of the operation of the start / stop switch 38 is released. Further, the operator does not need to wait until the last operation of the dishwashing storage 10 is started.

If the currently operating tableware disinfection storage 10 is abnormally stopped due to a failure or the like, an operation end signal from the storage 10 is not input to the next tableware sterilization storage 10, and the operation is sequentially performed. Will be interrupted. However, in the tableware disinfection storage 10 of the embodiment, the operation is started even when the countdown of the delay timer 42 that starts counting by the operation start signal of the previous tableware disinfection storage 10 is completed. Even if no signal is input,
Sequential operation can be continued without interruption.

Next, when it is possible to secure a power supply capacity capable of operating all the dishwashing storages 10 simultaneously, if the set time of all the delay timers 42 is set to zero, the first dishwashing storage 10 The start operation of the operation / stop switch 38 can start the operation of all the tableware disinfection storages 10. That is, even when all tableware disinfection storages 10 are operated at the same time, there is no need to perform a complicated operation of operating the start / stop switches 38 of all tableware sterilization storages 10.

If the set time of the delay timer 42 of the first tableware disinfection storage 10 is set to a value other than zero, the required time from when the operation / stop switch 38 is operated to when the operation is actually started is required. A delay time can be provided. Therefore, in a food and beverage facility in which the power supply capacity can be secured when a predetermined time period is reached, the set time for starting operation during that time period is set to the delay timer 42 of the first dishwashing storage 10.
, It is not necessary for the operator to wait until the time period.

The processing after the power recovery from the power outage of the eating and drinking facility is, as described above, performed in each tableware disinfection storage 1.
Since 0 is set to return to the beginning of the state at the time of the power failure, the plurality of dishwashing storages 10 are not operated at the same time. The operation panel 40 only reports that there was a power outage.
Is displayed, when the operator restarts the operation of the dishwashing storage 10, it is possible to recognize that a power failure has occurred by the power failure display on the operation panel 40.

(Embodiment) FIG. 5 shows an apparatus in which the operation method according to another embodiment is carried out. A timer device 44 is provided in the power supply equipment 15, and the set time of the timer device 44 is set. Upon completion of the counting, power is supplied from the power supply equipment 15 to the first tableware disinfection storage 10.

In the first tableware disinfection storage 10, the same operation as when the above-mentioned operation / stop switch 38 is started is performed on condition that power is supplied from the power supply equipment 15. Therefore, if the timer device 44 sets the time during which the power supply capacity capable of operating the dishwashing storage 10 in the power supply facility 15 is secured, the operation of all the dishwashing storages 10 can be performed sequentially. If the set times of all the delay timers 42 are set to zero as described above, it is also possible to simultaneously operate all the dishwashing storages 10.

In the above-described embodiment, a delay timer for providing a delay time from the start operation of the operation / stop switch to the actual start of operation in the individual operation of the tableware disinfection storage is provided from the previous tableware sterilization storage. Is used as the operation start means when no operation end signal is input, but another timer may be used.

[0030]

As described above, in the operation method of the dishwashing storage according to the present invention, a plurality of dishwashing storages are sequentially operated only by starting the operation of the first dishwashing storage. Therefore, even if the power supply capacity for operating all the vehicles is not ensured, the operation start and operation of all the tableware disinfection storages can be performed by one operation. That is, the operator can be freed from the troublesome operation of operating the operation / stop switches of all the dishwashing storages, and the operator does not need to wait until the last operation of the dishwashing storage is started. . In addition, even when the power supply capacity for simultaneously operating all the tableware disinfection storages can be ensured, all the tableware disinfection storages can be operated and terminated only by operating the operation / stop switch of the first tableware disinfection storage. Yes, the operator does not need to operate the start / stop switch of every dishwashing storage.

Even if an operation end signal is not input due to an abnormal stop of the previous dishwashing storage, the next dishwashing is performed by the end of the timer which starts counting from the start of the operation of the previous dishwashing storage. Since the operation of the storage can be started automatically, the interruption of the operation in sequence is prevented.

Further, the start of the operation of the tableware disinfection storage can be delayed by a timer until a time zone in which the power supply capacity can be secured, so that the operator does not need to wait until the time zone is reached. Furthermore, the tableware disinfection storage can be started to operate on condition that power is supplied to the tableware disinfection storage, so, for example, if the time of power supply is set using a weekly timer or the like, the specified day of the week can be designated. Automatic operation can be started at the designated time, so that the operator's hand is not bothered.
