Condition warning system, control system and method for pot and pan washing machine
View Patent ↗A condition warning system for an apparatus such as a pot and pan washing machine, a control system and control methods for a pot and pan washing machine are provided. The condition warning system includes a control system that monitors operational, safety or compliance parameters of an apparatus, and a light that illuminates a location below (or above) an operator's direct line of sight, and which is outside of the operator's direct line of sight. The control system and control methods include a punitive wash action lockout, an extended wash cycle time, and a deep clean wash cycle.
1. A method of washing wares in a continuous motion style washing machine, said method comprising the steps of:
providing by a control system selection options of at least two different wash modes, said at least two different wash modes including at least a standard wash mode and a deep cleaning wash mode; and either
initiating a standard washing cycle upon selection of said standard wash mode, said first washing cycle including the steps of:
activating a wash pump by said control system to circulate a fluid within a wash tank;
maintaining a temperature of said fluid within a standard temperature range during said standard washing cycle; and
locking out said wash pump upon completion of said standard washing cycle; or
initiating a deep cleaning washing cycle upon selection of said deep cleaning wash mode, said deep cleaning washing cycle including the steps of:
operating continuously a wash pump by said control system to circulate a fluid within said wash tank during a first segment of said deep cleaning washing cycle;
maintaining a temperature of said fluid within a deep cleaning temperature range during said first segment of said deep cleaning washing cycle, an upper limit of said deep cleaning temperature range being higher than an upper limit of said standard temperature range;
deactivating and subsequently reactivating said wash pump for periodic intervals during an energy saving idle mode segment of said deep cleaning washing cycle after completion of said first segment, thereby creating a plurality of respective deactivated and reactivated periods; and
maintaining a temperature of said fluid within a lower deep cleaning temperature range during said energy saving idle mode segment of said deep cleaning washing cycle, a lower limit of said lower deep cleaning temperature range being lower than a lower limit of said deep cleaning temperature range.
2. The method as claimed in claim 1 wherein said deactivated periods are generally longer than said reactivated periods.
3. The method of claim 2 , wherein deactivated and reactivated periods are defined by respective time intervals, each time interval being several minutes or more.
4. The method as claimed in claim 1 wherein at least one of said steps of maintaining temperatures of said fluid include the step of energizing a heating element solely during operation of said wash pump.
5. The method as claimed in claim 1 wherein at least one of said steps of maintaining temperatures of said fluid include the step of energizing a heating element both during operation and during deactivation of said wash pump.
6. The method as claimed in claim 1 wherein said deactivated and reactivated periods are defined by respective first time intervals while the temperature of said fluid is above said lower deep cleaning temperature range, and wherein said deactivated and reactivated periods are defined by respective second time intervals after the temperature of said fluid is lowered to a temperature within said lower deep cleaning temperature range.
7. The method of claim 6 , wherein each of said first and second time intervals defining each of said deactivated and reactivated periods is several minutes or more.
8. The method of claim 7 , wherein said first and second time intervals are 10 and 15 minutes, respectively, for each deactivated period.
9. The method of claim 8 , wherein said first and second time intervals are 10 and 5 minutes, respectively, for each reactivated period.
10. The method of claim 7 , wherein said first and second time intervals are 10 and 5 minutes, respectively, for each reactivated period.
11. The method of claim 1 , wherein deactivated and reactivated periods are defined by respective time intervals, each time interval being several minutes or more.
