Abstract

An ice-making machine and method of maintaining and cleaning an ice-making machine are provided. The ice-making machine has predictive maintenance and cleaning. Operational conditions of the ice-making machine, such as, for example, water quality, are used to establish service intervals and/or types of service, and the service intervals and/or types of service are indicated to the user with a lead-time to allow for timely obtaining the service.

Claims (25)

1. An ice-making machine comprising:

a compressor, a condenser, an evaporator, and a sensor, wherein said sensor determines an operational condition of the ice-making machine, and a microprocessor that schedules a service based at least in part when said operational condition reaches a predetermined level and on a service interval derived from said operational condition.

2. The ice-making machine of claim 1 , wherein said operational condition is a quality of water supplied to the ice-making machine.

3. The ice-making machine of claim 2 , wherein said sensor measures water conductivity.

4. The ice-making machine of claim 2 , wherein said sensor measures a total dissolved solid content of said water.

5. The ice-making machine of claim 1 , further comprising an indicator in communication with said sensor, wherein said indicator notifies a user of scheduling of said service.

6. The ice-making machine of claim 5 , wherein said indicator is a visual indicator.

7. The ice-making machine of claim 5 , wherein said indicator is an audio indicator.

8. The ice-making machine of claim 1 , further comprising an automatic service system operably connected to the ice-making machine that provides said service to the ice-making machine automatically.

9. The ice-making machine of claim 8 , wherein said microprocessor is in communication with said automatic service system and said sensor, wherein said service is a plurality of services, and wherein one or more of said plurality of services can be automatically actuated by said microprocessor.

10. The ice-making machine of claim 8 , further comprising an indicator in communication with said sensor, wherein said indicator notifies a user of actuation of said automatic service.

11. A method of servicing an ice-making machine comprising:

determining an operational condition of the ice-making machine; and

scheduling a service of the ice-making machine based at least in part when said operational condition reaches a pre-determined level and on a service interval derived from said operational condition.

12. The method of claim 11 , wherein said operational condition is a quality of water supplied to the ice-making machine.

13. The method of claim 11 , wherein said operational condition is determined by measuring water conductivity.

14. The method of claim 12 , wherein said operational condition is determined by measuring a total dissolved solid content of said water.

15. The method of claim 11 , further comprising; notifying a user of the scheduling of the service.

16. The method of claim 15 , wherein the user is notified visually.

17. The method of claim 15 , wherein the user is notified audibly.

18. The method of claim 11 , further comprising:

determining a type of service required by the ice-making machine based at least in part upon said operational condition.

19. The method of claim 18 , further comprising: notifying a user of the type of service required by the ice-making machine.

20. The method of claim 11 , further comprising:

automatically providing the service to the ice-making machine via an automatic service system operably connected to the ice-making machine.
