Abstract
An example automatic kitchen cleaning system includes a control box configured to, in response to receipt of the start signal to initiate the first cleaning operation of the cooking range exhaust system, causing the first detergent and water to be mixed in a reservoir at the first target mixing ratio for form the first cleaning solution. The control box is further configured to, in response to receipt of the start signal to initiate the second cleaning operation of the waste conduit, causing the second detergent and water to be mixed in the reservoir at the second target mixing ratio to form the second cleaning solution.
Claims23
A system, comprising:
- a plurality of nozzles coupled to a hood conduit and arranged to spray at least a hood zone of a cooking range exhaust system with a first cleaning solution;
- a waste conduit configured to receive the sprayed first cleaning solution from the hood zone as runoff and provide the runoff from the cooking range exhaust system to a drain;
- a waste conduit cleaning conduit arranged downstream of the plurality of nozzles and configured to dispense a second cleaning solution into the waste conduit;
- and
- a control box configured to:
- in response to receipt of a first start signal to initiate a first cleaning operation of the cooking range exhaust system:
- cause the first cleaning solution comprising a mixture of a first detergent and water having a ratio based on a first target mixing ratio to be mixed in a reservoir at the first target mixing ratio to form the first cleaning solution;
- monitor a float switch in the reservoir;
- cause a first electronically-controlled valve to open upon actuation of the float switch thereby indicating the first target mixing ratio has been reached;
- and
- cause the first cleaning solution to be provided to the plurality of nozzles via the hood conduit;
- and
- in response to receipt of a second start signal to initiate a second cleaning operation of the waste conduit:
- cause the second cleaning solution comprising a mixture of a second detergent and water having a ratio based on a second target mixing ratio to be mixed in the reservoir at the second target mixing ratio to form the second cleaning solution;
- monitor the float switch in the reservoir;
- cause a second electronically-controlled valve to open upon actuation of the float switch thereby indicating the second target mixing ratio has been reached;
- and
- cause the second cleaning solution to be dispensed into the waste conduit via the waste conduit cleaning conduit.

A system, comprising:
- a first nozzle coupled to a hood conduit and arranged to spray a hood zone of a cooking range exhaust system with a first cleaning solution;
- a second nozzle coupled to a flue conduit and arranged to spray a flue zone of the cooking range exhaust system with a second cleaning solution;
- a waste conduit of the cooking range exhaust system, the waste conduit configured to receive runoff from the hood zone and the flue zone;
- a third nozzle coupled to a waste conduit cleaning conduit and arranged to spray the waste conduit with a third cleaning solution;
- and
- a control box configured to:
- in response to receipt of a first start signal to initiate a first cleaning operation of the cooking range exhaust system, determine actuation of a float switch corresponding to the first cleaning solution being mixed to a first target mixing ratio, cause a first valve to open to cause the first cleaning solution at the first target mixing ratio to be provided to the first nozzle via the hood conduit;
- in response to receipt of a second start signal to initiate a second cleaning operation of the cooking range exhaust system, determine actuation of a float switch corresponding to the second cleaning solution being mixed to a second target mixing ratio, cause a second valve to open to cause the second cleaning solution at the second target mixing ratio to be provided to the second nozzle via the flue conduit;
- and
- in response to receipt of a third start signal to initiate a third cleaning operation of the cooking range exhaust system, determine actuation of a float switch corresponding to the third cleaning solution being mixed to a third target mixing ratio, cause a third valve to open to cause the third cleaning solution at the third target mixing ratio to be provided to the third nozzle via the waste conduit cleaning conduit.

A system, comprising:
- a first nozzle coupled to a first conduit and arranged to spray at least a first zone of a cooking range exhaust system with a first cleaning solution;
- a waste conduit configured to receive the sprayed first cleaning solution from the first zone as runoff and provide the runoff from the cooking range exhaust system to a drain or reservoir;
- a second nozzle coupled to a waste conduit cleaning conduit configured to dispense a second cleaning solution into the waste conduit, wherein the second nozzle directs spray into the waste conduit;
- and
- a control box configured to:
- in response to receipt of a first start signal, cause the first cleaning solution comprising a detergent and water to be provided to the first nozzle through the first conduit by opening a first valve to provide water to the first conduit and opening a second valve to provide the detergent to the first conduit in a first ratio such that the water and the detergent are mixed upon entering the first conduit;
- and
- in response to receipt of a second start signal, cause the second cleaning solution comprising the detergent and water to be provided to the second nozzle through the waste conduit cleaning conduit by opening the first valve to provide water to the waste conduit cleaning conduit and opening the second valve to provide the detergent to the waste conduit cleaning conduit such that the water and the detergent are mixed upon entering the waste conduit cleaning conduit.
