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 comprising:
a master base configured to communicatively connect each of one or more food holding chambers to a central controller;
a first food holding chamber having a first chamber housing, a first male upstream power and communications port that extends away from a bottom surface of the first chamber housing, a first female downstream power and communications port located into a top surface of the first chamber housing, and a plurality of first alignment structures that each comprise a post separate and spaced apart from the first male upstream power and communications port and that extend away from the bottom surface of the first chamber housing, in an engagement direction between the first male upstream power and communication port and first female downstream power and communication port, a greater distance than the first male upstream power and communications port extends away from the bottom surface of the first chamber housing; and
a second food holding chamber connecting the master base to the first food holding chamber, the second food holding chamber having a second chamber housing and second alignment structures, the second alignment structures each comprise a hole into a top surface of the second chamber housing, the second alignment structures having a complementary shape to the first alignment structures and cooperating with the first alignment structures to align the first food holding chamber with the second food holding chamber when the first and second food holding chambers are stacked to form a food holding unit;
wherein the second food holding chamber has a second male upstream power and communications port that extends away from a bottom surface of the second chamber housing and a second female downstream power and communications port located into a top surface of the second chamber housing such that the engagement direction of the first male upstream power and communications port and the second female downstream power and communications port is parallel to an insertion direction of the first alignment structure into the second alignment structure, and
wherein the first alignment structures and the second alignment structures center and stabilize the first food holding chamber on the second food holding chamber.

2. The modular food holding system of claim 1 , wherein the first food holding chamber includes first securing mechanisms on the bottom surface of the first chamber housing, wherein the first alignment structures extend away from the bottom surface of the first chamber housing a greater distance than the first securing mechanisms; and
wherein the second food holding chamber includes second securing mechanisms complementary to the first securing mechanisms and formed in the top surface of the second chamber housing.

3. The modular food holding system of claim 2 , wherein the first alignment structures are arranged at the corners of the bottom surface of the first chamber housing.

4. The modular food holding system of claim 3 , wherein the first securing mechanisms are arranged at the sides of the bottom surface of the first chamber housing and the first securing mechanisms extend in an elongated direction parallel to an adjacent side of the bottom surface, wherein at least one of the first securing mechanisms is perpendicular to another of the first securing mechanisms.

5. The modular food holding system of claim 2 , wherein the first securing mechanisms are brackets and the second securing mechanisms are openings.

6. The modular food holding system of claim 1 , wherein the master base is directly connected to the second food holding chamber.

7. The modular food holding system of claim 6 , wherein the second food holding chamber includes a chamber alignment structure on the bottom surface of the second chamber housing, and the master base includes a base alignment structure on a top surface of a base housing, the base alignment structure cooperating with the chamber alignment structure to align the second food holding chamber with the master base when the second food holding chamber is stacked atop the master base to form a food holding unit.

8. The modular food holding system of claim 7 , wherein the chamber alignment structure is a post that extends outward from the bottom surface of the second chamber housing.

9. The modular food holding system of claim 8 , wherein the base alignment structure is a hole that is sized and shaped to receive the post.

10. The modular food holding system of claim 6 , wherein the second food holding chamber includes a chamber securing mechanism on the bottom surface of the second chamber housing, and the master base includes a base securing structure on a top surface of the base housing.

11. The modular food holding system of claim 10 , wherein the chamber securing mechanism is a bracket and the base securing mechanism is an opening that is sized and shaped to receive the bracket.

12. The modular food holding system of claim 6 , further comprising an expansion base operatively connected to the master base.

13. The modular food holding system of claim 12 , wherein the expansion base is operatively connected to the master base with an upstream power and communications port disposed in a side surface of an expansion base housing.

14. The modular food holding system of claim 12 , wherein the expansion base includes an expansion alignment structure on a top surface of an expansion base housing, the expansion base alignment structure cooperating with a chamber alignment structure formed in a bottom surface of a third food holding chamber to align the third food holding chamber with the expansion base when the third food holding chamber is stacked atop the expansion base to form a food holding unit.

15. A modular food holding system comprising:
a master base configured to communicatively connect each of one or more food holding chambers to a central controller;
a first food holding chamber having a first chamber housing, a first female upstream power and communications port located into a bottom surface of the first chamber housing, a first male downstream power and communications port located on a top surface of the first chamber housing, and a plurality of first alignment structures, each first alignment structure of the plurality comprising a hole on the bottom surface of the first chamber housing; and
a second food holding chamber connecting the master base to the first food holding chamber, the second food holding chamber having a second chamber housing and a plurality of second alignment structures, each second alignment structure of the plurality comprising a post that extends away from a top surface of the second chamber housing, the second alignment structures having complementary shapes to the first alignment structures and cooperating with the first alignment structure sto align the first food holding chamber with the second food holding chamber when the first and second food holding chambers are stacked to form a food holding unit;
wherein the second food holding chamber has a second female upstream power and communications port located into a bottom surface of the second chamber housing and a second male downstream power and communications port extending from a top surface of the second chamber housing, wherein the second alignment structures are separate and spaced apart from the second male downstream power and communications port, and the second alignment structures extend away from the top surface of the second chamber housing, in an engagement direction of the first female upstream power and communications
