Abstract

A modular food holding system includes a plurality of individual modularized food holding chambers, each of the plurality of food holding chambers being physically and communicatively removably connected to one another. Each of the food holding chambers includes a food holding cavity and at least one of a heating element and/or a cooling element for heating or cooling the food holding cavity. A chamber base is physically and communicatively removably connected to one of the food holding chambers and operation of at least one food holding chamber is controlled by the chamber base.

First claim

What is claimed:

1. A modular food holding system communicatively connected to a central controller, comprising:
a master base configured to communicatively connect each of one or more food holding chambers to the central controller;
a first food holding chamber directly connected to the master base; and
a second food holding chamber connected to the master base through an expansion base connected to the master base;
wherein the master base is configured to establish a communication connection between the central controller and the first and second food holding chambers,
wherein the first and second food holding chambers receive control commands from the central controller, and
wherein the second food holding chamber is connected to the expansion base, and wherein the expansion base is directly connected to the master base and is configured to communicatively connect one or more additional food holding chambers and one or more additional expansion bases to the master base.

2. The modular food holding system of claim 1 , wherein the first food holding chamber has an identical structure to the structure of the second food holding chamber.

3. The modular food holding system of claim 2 , wherein each food holding chamber includes both a downstream connector configured to connect to a food holding chamber and an upstream connector configured to communicatively connect the food holding chamber to the master base.

4. The modular food holding system of claim 3 , wherein the upstream and downstream connectors of each food holding chamber includes one or both of an electrical power connector or a communication connector.

5. The modular food holding system of claim 3 , wherein the first food holding chamber is communicatively connected to the central controller through the master base and the second food holding chamber is communicatively connected to the central controller through the first food holding chamber and the master base.

6. The modular food holding system of claim 1 , wherein the first and second food holding chambers include one or more electrical components, and the electrical components include only one or more of the following: a unit controller, a timer switch, a heating element, a fan or an indicator light; and wherein the one or more electrical components are communicatively connected to the master base by one or more connectors or wiring within the first and second food holding chambers.

7. The modular food holding system of claim 1 , wherein at least one of the first and second food holding chambers includes a sensor, and wherein the at least one of the first and second food holding chambers is controlled based upon sensor data from the sensor.

8. The modular food holding system of claim 7 , wherein the at least one of the first and second food holding chambers includes a unit controller, which unit controller receives the sensor data from the sensor, and the unit controller controls the at least one of the first and second food holding chambers based upon the sensor data received.

9. The modular food holding system of claim 1 , wherein the first food holding chamber receives electrical power from the master base and the second food holding chamber receives electrical power from either (i) the first food holding chamber or (ii) the expansion base.

10. The modular food holding system of claim 9 , wherein each of the first and second food holding chamber includes an electrical heating or cooling element and a unit controller that controls operation of the electrical hearing or cooling element.

11. The modular food holding system of claim 1 , wherein the central controller is incorporated within the master base.

12. A computer-implemented method for monitoring a plurality of food holding chambers of a modular food holding system, comprising:
connecting a first food holding chamber to a master base;
connecting a second food holding chamber to the first food holding chamber, wherein connecting the second food holding chamber to the first food holding chamber communicatively connects the second food holding chamber to the master base through an expansion base connected to the master base, wherein the second food holding chamber is connected to the expansion base, and wherein the expansion base is directly connected to the master base and is configured to communicatively connect one or more additional food holding chambers and one or more additional expansion bases to the master base;
connecting, by a communications link, a central controller to a master base;
receiving, via the communications link, first operating parameters regarding operation of the first food holding chamber and second operating parameters regarding operation of the second food holding chamber;
communicating, from the master base, the first operating parameters to the first food holding chamber;
communicating, from the master base through the expansion base, the second operating parameters to the second food holding chamber;
controlling, by a first unit controller, the operation of the first food holding chambers based upon the first operating parameters; and
controlling, by a second unit controller, the operation of the second food holding chambers based upon the second operating parameters.

13. The computer-implemented method of claim 12 , further comprising:
receiving from the central controller, via the communications link, a control command directed to either or both of the first food holding chamber or the second food holding chamber; and
determining at least one of the first or second operating parameters based upon the received control command.

14. The computer-implemented method of claim 12 , further comprising:
receiving from the central controller, via the communications link, a control command directed to either or both of the first food holding chamber or the second food holding chamber,
wherein the control command causes either or both of the first food holding chamber or the second food holding chamber to perform one or more of the following actions:
presenting an alert, illuminating an indicator light, displaying a countdown, controlling the temperature within the food holding chamber, or controlling the humidity within the food holding chamber.

15. The computer-implemented method of claim 12 , wherein the communications link includes one or more of the following: a cord, a wireless connection, or a direct connection between a plug of the central controller and a socket of the master base.

16. The computer-implemented method of claim 12 , further comprising:
communicating to the central controller, via the communications link, data from one or both of the first food holding chamber or the second food holding chamber, wherein the data comprises one or more of the following: temperature within the food holding chamber, humidity within the food holding chamber, heat source location within the food holding chamber, operating status of the food holding chamber, operating parameters of the food holding chamber, or sensor data from one or more sensors disposed within the one or more food holding chambers; and
causing the central controller to present information associated with at least a portion of the received data to a user via a display of the central controller.

17. The computer-implemented method of claim 12 , wherein the first food holding chamber has a structure identical to the structure of the second food holding chamber.

18. The computer-implemented method of claim 17 , wherein each food holding chamber includes both a downstream connector config
