A system for storing articles can have at least two operating modes. In the first mode, gases are evacuated from the system whereby the articles are stored at a pressure less than the pressure at the exterior of the system. In the second mode, gases are evacuated while the system is open to the admittance of gases from the exterior of the system whereby the articles are ventilated by the admitted gases. The system also can have a third operating mode wherein both the first and second modes are rendered inoperative. The storage system can function so that when the articles are stored in the first mode, gases are intermittently removed from the system whereby the pressure at which the articles are stored is maintained at less than the pressure at the exterior of the system. The storage system can be located in a refrigeration appliance such as a household refrigerator.

Storage systems

The invention concerns a storage unit that is adapted to be located in a refrigeration appliance. The storage unit includes a holding compartment for holding articles the temperature of which is to be controlled. The holding compartment is adapted to be placed in air flow communication with a source of cold air whereby the cold air may be delivered to the holding compartment. An air-flow passageway for recirculating air discharged from the holding compartment back to the holding compartment is provided along with a mixing area where the cold air and the recirculated air may be mixed in selected quantities. A user interface providing for the selection of a temperature-control procedure from a group of available temperature-control procedures for application to the interior of the holding compartment is included. The storage unit can include a controller for controlling the implementation of the temperature-control procedure selected by the user.

Temperature-controlled compartment

A defrosting and chilling compartment that can be incorporated into the fresh food compartment of a refrigerator includes separate and independent pathways for selectively conducting warming or cooling air, respectively, to a holding section in the compartment where an item to be defrosted or chilled is located. Certain of the pathways are used to conduct warming air and certain other pathways are used to conduct cooling air. A heating device is associated with the pathways that conduct warming air, and the pathways that conduct cooling air are associated with a source of cooling air. Separate air-moving devices, such as fans for example, can be provided for the separate pathways. The pathways can include a closure device for selectively and variably opening and closing the pathways.

Refrigerator defrosting and chilling compartment

An ice-making system is adapted to operate within a section of a refrigeration appliance where the ice-making system and the ice made in the ice-making system are exposed to a temperature greater than zero degrees Centigrade. When installed in the fresh food compartment of a refrigerator that also has a freezer section compartment, the refrigeration system furnishes a cooling effect to the freezer compartment sufficient to maintain the freezer compartment at a temperature of zero degrees or less and separately furnish to the ice-making unit a cooling effect sufficient to freeze water for making ice in the ice-making unit of the ice-making system. The ice-making system can include a reservoir that is operatively associated with the ice-making unit of the ice-making system for delivering water to the ice-making unit and for receiving water returned from the ice-making unit.

Ice-making system for refrigeration appliance

A damper cleaning apparatus for a two compartment refrigerator having a damper for controlling airflow between compartments. The damper cleaning apparatus includes a damper drive mechanism for opening and closing the damper. A controller for controlling the damper drive mechanism repeats a cleaning operation at a set interval. The cleaning operation includes plural repetitions of at least partially opening the damper and then at least partially closing the damper. Optionally, the controller waits for the defrosting apparatus to be turned off and then subsequently performs the cleaning operation.

Automatic defrost controller including air damper cleaning

A damper apparatus for controlling airflow between compartments in a two compartment refrigerator having a door includes a controller for controlling opening and closing of a damper; and a door sensor connected to the controller for detecting when the door is open. If the controller determines that the door has remained closed for a set period, the controller maintains the damper in the closed position. A method for cleaning a damper in a refrigerator includes a steps of defrosting a refrigeration apparatus of the refrigerator, at least partially opening the damper, followed by waiting for a set period and then at least partially closing the damper. The steps of at least partially opening and waiting are repeated a set number of times and then a cooling operation of the refrigeration apparatus is commenced.

Automatic defrost controller including air damper control

A cooling enhancement device causes rapid cooling of an item placed within a cooling unit. The device includes a temperature simulating arrangement (e.g., including a heat generating element adjacent a temperature sensor of the cooling unit) to simulate an artificial temperature within the cooling unit. In one example, the device includes a control system connected to control the operation of the temperature simulating arrangement. The device also includes a setting component to provide user control. In one example, the setting component is connected to communicate a rapid cooling setting input by the user to the control system.
