Abstract
A method for cleaning a cooking range exhaust system includes, in response to receipt of a start signal at a control box of a cooking range exhaust cleaning system to initiate a cleaning operation, causing a cleaning solution comprising a mixture of detergent and water having a ratio based on a target mixing ratio to be provided to a supply line, and causing an electronically-controlled valve to open to facilitate provision of the cleaning solution to a nozzle coupled to the electronically-controlled valve via a conduit for a predetermined period of time, wherein the nozzle is arranged to spray a zone of the cooking range exhaust system.
Claims12
A method, comprising:
- in response to receipt of a start signal at a control box of a cooking range exhaust cleaning system to initiate a cleaning operation:
- causing a reservoir to fill with a mixture of detergent and water having a ratio based on a target mixing ratio, wherein causing the reservoir to fill with the mixture of detergent and water includes monitoring a float switch mechanism at least partially in the reservoir to determine when the reservoir has filled to a minimum threshold with the water prior to causing the detergent to be added to the reservoir;
- causing a cleaning solution comprising the mixture of detergent and water having the ratio based on a target mixing ratio to be provided to a supply line from the reservoir;
- and
- causing an electronically-controlled valve to open to facilitate provision of the cleaning solution to a nozzle coupled to the electronically-controlled valve via a conduit for a predetermined period of time, wherein the nozzle is arranged to spray a zone of a cooking range exhaust system.
At least one machine-readable medium including instructions that, when executed by processing circuitry, cause the processing circuitry to:
- in response to receipt of a start signal to initiate a cleaning operation:
- cause a reservoir to fill with a mixture of detergent and water having a ratio based on a target mixing ratio, wherein causing the reservoir to fill with the mixture of detergent and water includes monitoring a float switch mechanism at least partially in the reservoir to determine when the reservoir has filled to a minimum threshold with the water prior to causing the detergent to be added to the reservoir;
- cause a cleaning solution comprising the mixture of detergent and water having the ratio based on a target mixing ratio to be provided to a supply line from the reservoir;
- and
- cause a valve to open to facilitate provision of the cleaning solution to a nozzle coupled to the valve via a conduit for a predetermined period of time, wherein the nozzle is arranged to spray a zone of a cooking range exhaust system.
