Abstract
A control system for delivering filtered liquid to a reservoir of a beverage machine. The liquid level within the reservoir is monitored, and when the liquid level is at or below a predetermined level, a valve opens to allow liquid to flow to the reservoir. Once the liquid level has reached or obtained a predetermined liquid fill level, the valve is closed.
Claims20
A control system for providing liquid from a liquid source to a beverage machine, the beverage machine including a reservoir configured to hold a volume of liquid, the control system comprising:
- a valve configured to selectively allow liquid to flow from the liquid source to the reservoir, wherein the valve comprises a valve transceiver;
- a liquid level sensor configured to detect a liquid level within the reservoir, wherein the liquid level sensor comprises a liquid level transceiver;
- and
- a controller in operative communication with the liquid level transceiver of the liquid level sensor and the valve transceiver of the valve wirelessly, the controller configured to:
- receive a low liquid signal from the liquid level sensor when the liquid level within the reservoir has reached a predetermined low liquid level;
- send an open valve signal to the valve to open the valve to allow liquid to flow into the reservoir;
- receive a liquid fill signal from the liquid level sensor when the liquid level within the reservoir has reached a predetermined liquid fill level;
- and
- send a close valve signal to the valve to close the valve stop the flow of liquid to the reservoir.
A control system for providing liquid from a liquid source to a beverage machine, the beverage machine including a reservoir configured to hold a volume of liquid, the control system comprising:
- a valve configured to selectively allow liquid to flow from the liquid source to the reservoir;
- a filter positioned between the liquid source and the valve, wherein the filter comprises a filter sensor;
- a liquid level sensor configured to detect a liquid level within the reservoir;
- and
- a controller in operative communication with the filter sensor, the liquid level sensor, and the valve, the controller configured to:
- receive a low liquid signal from the liquid level sensor when the liquid level within the reservoir has reached a predetermined low liquid level;
- send an open valve signal to the valve to open the valve to allow liquid to flow into the reservoir;
- receive a liquid fill signal from the liquid level sensor when the liquid level within the reservoir has reached a predetermined liquid fill level;
- and
- send a close valve signal to the valve to close the valve stop the flow of liquid to the reservoir, and
- wherein the controller is further configured to:
- receive a filter level signal from the filter sensor when a filter level of the filter has reached a predetermined filter level;
- and
- send a filter level alert.
A control system for providing liquid from a liquid source to a beverage machine, the beverage machine including a reservoir configured to hold a volume of liquid, the control system comprising:
- a valve configured to selectively allow liquid to flow from the liquid source to the reservoir;
- a filter positioned between the liquid source and the valve, wherein the filter comprises a filter sensor configured to detect a liquid quality level of liquid flowing to the reservoir;
- a liquid level sensor configured to detect a liquid level within the reservoir;
- and
- a controller in operative communication with the filter sensor, the liquid level sensor, and the valve, the controller configured to:
- receive a low liquid signal from the liquid level sensor when the liquid level within the reservoir has reached a predetermined low liquid level;
- send an open valve signal to the valve to open the valve to allow liquid to flow into the reservoir;
- receive a liquid fill signal from the liquid level sensor when the liquid level within the reservoir has reached a predetermined liquid fill level;
- and
- send a close valve signal to the valve to close the valve stop the flow of liquid to the reservoir, and
- wherein the controller is further configured to:
- receive a filter level signal from the filter sensor when a filter level of the filter has reached a predetermined filter level;
- and
- send a filter level alert, and
- wherein the controller is further configured to:
- receive a liquid quality signal from the filter sensor when the liquid flowing to the reservoir has reached a predetermined liquid quality.
