A refreshment center having a modular construction and including a mini door and a frame is described. The mini door is fabricated and assembled separate from the frame, and the mini door includes a hinge system and a trigger. The mini door provides quick and convenient access to the refreshment center by being simple and easy to open and close. The frame, in an exemplary embodiment, is a one piece plastic molded part which serves as the main structural member of the assembly. The frame includes first and second spaced apart planar members, and further includes a keeper slot and a keeper for being inserted within the slot. The keeper extends from the slot and at least partially through a keeper slot in the door trim. The frame further includes a switch cavity for housing at least a portion of a switch assembly. A switch bracket is provided to be secured over the switch cavity and is engaged to the frame by a screw. The mini door is secured to the frame by a hinge system which includes a hinge arm which extends between, and is secured to, the mini door and the frame. More specifically, at the frame, the hinge arm is secured to a slide located between the frame first and second planar members. Hinge pins are secured to the mini door outer door member and extend from the outer door member and through the bushings of pivot slides. The pivot slides are secured to the frame by retainers, and springs are provided to maintain the pivot slides in position within the retainer. The switch assembly includes a switch having a switch actuator arm. Wires extend from the switch to a harness which mates with a receptacle. The receptacle is in electric circuit with a light in the fresh food compartment. The light used to illuminate the refreshment center can be one of the existing lights used in current side-by-side refrigerators since the inner cover is transparent.

Modular refreshment center for refrigerator fresh food compartment

A mechanism to control the temperature in the freezer and fresh food compartments of a side-by-side refrigerator includes an elongated support plate mounted in the upper portion of the fresh food compartment. A fresh food thermostat is mounted under the plate adjacent to the mullion separating the compartments and its control shaft is aligned with an opening in the plate. A pinion gear is connected to the shaft and is positioned above the plate. A freezer thermostat is mounted under the plate at a position more remote from the mullion and its control shaft is aligned with an opening in the plate. A pinion gear is connected to the control shaft and is positioned above the plate. A fresh food rack gear is slidingly mounted on the plate remote from the mullion and includes an elongated arm with teeth that engage the fresh food pinion gear. A freezer rack gear is slidingly mounted on the plate close to the mullion and includes an elongated arm with teeth that engage the teeth on the freezer pinion gear. Each rack gear includes a tab for user movement of that rack gear to adjust the setting of the corresponding thermostat.

Refrigerator with improved control mechanism

A refrigerator has a refrigeration control mechanism including a base mounted in the food storage compartment. The base includes a support plate extending generally horizontally side-to-side in the compartment. A pair of thermostats are mounted under opposite end portions of the plate and a lamp is mounted between the thermostats. Each thermostat has an operating handle extending forward of the plate. A bezel is removably mounted to the base and extends along the front of the plate aligned with the thermostats and lamp. The bezel includes two slots which receive the handles and permit sliding movement of the handles to adjust the thermostats. The slots and handles are sized to permit removal of the bezel without removing the handles. A light shield, removably mounted to the base, includes a bottom wall extending under the plate, aligned with the thermostats and lamp, and a frame encompassing the periphery of the bezel. The upper edge of the frame overlaps the upper edge of the bezel.

A mechanism to control air flow between the freezer and fresh food compartments of a refrigerator includes an elongated air flow tube and a flow control housing with mating planar surfaces angled relative to the longitudinal axis of the air flow tube. A mating gasket is positioned between the planar surfaces and joined to each with adhesive. An electrical conductor extends through the air flow passageway in the tube and housing and includes a plug of material around the conductor's protective cover. A recess in the housing mounts the plug with an angled surface of the plug filling a matching interruption in the housing's planar surface to prevent air leaks around the conductor. The housing and plug include cooperating dimples which receive a capillary tube extending through the air passage.

Refrigerator air flow control mechanism

A side by side refrigerator has a vertical evaporator formed from an elongated tube wrapped with a ribbon of material having spine fins extending substantially perpendicular from the elongated tube. The elongated tube has elongated straight runs joined by return bent ends to define a vertically extending evaporator having a generally oval spiral or configuration. In one embodiment, the elongated straight runs are spaced from each other throughout the vertical length of the evaporator to provide a space of constant area for air flow. In other embodiments, the lower end of the evaporator has the elongated straight runs spaced from each other to provide an entrance passage for air with the remainder of the evaporator having some of the elongated straight runs at predetermined locations on at least one side of the evaporator offset inwardly towards the other side of the evaporator so that the fins on the offset elongated straight runs overlap the fins on the elongated straight runs on the other side of the evaporator to enhance 'mixing' of the air flow around the various runs of the evaporator. The evaporator may have one of the elongated straight runs on one side of the evaporator moved into vertical alignment with adjacent elongated straight runs on the other side of the evaporator to which they are connected to provide a space intermediate the length of the evaporator for a defrost heater.

Spine fin refrigerator evaporator having generally oval spiral

A spine fin refrigerator evaporator is formed of lower and upper sections of elongated straight runs, which have fins thereon and have their ends connected to each other by return bent ends. The lower section is formed with two rows of the elongated straight runs in an A shape to provide a passage therebetween through which air initially flows through the evaporator so that frost can be gathered without blocking air flow therethrough. The upper section has three rows of the elongated straight runs with the fins of adjacent rows overlapping each other to provide an efficient heat transfer from the refrigerant in the elongated straight runs to the air whereby the lower and upper sections combine to provide a practical and efficient evaporator. If desired, the upper and lower sections can be vertically spaced from each other to have a defrost heater disposed therebetween.

Spine fin refrigerator evaporator

A refrigerator includes an evaporator formed from an elongated tube wrapped with a ribbon of material having spine fins extending perpendiculary from the tube. Elongated, horizontal passes of tube are arranged in vertically extending rows defining vertically extending air flow passages. Fins extending into the lower portions of the air flow passages are bent from their perpendicular relationship with the tube.
