POWER BUS OF A REMOVABLE REFRIGERATOR SHELF FOR SUPPLYING ADMISSIBLE TEMPERATURE GRADIENT BETWEEN COMPARTMENTS

摘要

PURPOSE: A power bus of a removable refrigerator shelf is provided to keep specific foods at high temperature gradient, to obtain cold temperature at a higher position in a compartment, and to position conveniently a control unit. CONSTITUTION: A refrigerator is composed of at least one compartment closed selectively by a door; at least one removable refrigerator shelf; and a unit for mounting the removable shelves in the compartment; a power bus(50) coupled electrically to a power unit; and a connector(60) disposed on the removable shelf. When the shelf is installed in the compartment by the mounting unit, the connector is coupled to the power bus to transmit power to the removable shelf. The power bus has grounding and power conducting agents(54,56). The refrigerator has a control circuit for controlling at least one atmospheric parameter in the compartment. A shelf portion of the control circuit is installed on the removable shelf. A main portion of the control circuit is separated from the removable shelf.
