A refrigerator includes a cabinet forming a storage space, a main door that opens and closes the storage space while defining an opening part that is in communication with the storage space, a sub-door mounted to the main door and configured to open and close the opening part, the sub-door including a panel assembly for allowing selective viewing of an inside of the opening part, the injection port is provided at a lower side of the sub-door to direct an insulating foaming solution to a space in the sub-door, a detection device for detecting an operation of a user, a lighting unit inside the refrigerator that turns on based on user operation to allow selective viewing of the inner side of the opening part, and a display unit inside the refrigerator at a position corresponding to the panel.

A refrigerator appliance or door assembly may include an enclosing body, a liquid reservoir, a level sensor, a water valve, and a liquid dispenser. The enclosing body may define an exterior surface and an interior surface. The liquid reservoir may be defined within the enclosing body between the exterior surface and the interior surface. The level sensor may be mounted to the liquid reservoir. The level sensor may be configured to detect a water volume within the liquid reservoir. The water valve may be mounted upstream from the liquid reservoir to selectively direct water thereto based on the detected water volume. The liquid dispenser may extend from the liquid reservoir and through the interior surface to an outlet aperture to selectively dispense water from the liquid reservoir.

A refrigerating appliance (100) is provided, which comprises: —at least one storage compartment (110) for storing goods to be refrigerated; —a refrigeration circuit comprising at least one evaporator (170) associated with said at least one storage compartment (110); —a control unit (172) configured to control operation of the refrigerating appliance (100); —at least one fan (171), configured to promote heat exchange between said at least one evaporator (170) and the at least one storage compartment (110), said at least one fan (171) being further configured to be switched between a first operative condition in which said at least one fan (171) is commanded to rotate, and a second operative condition in which said at least one fan (171) is commanded to not rotate; —a MEMS pressure sensor (180) configured to measure the pressure inside said at least one storage compartment (110) and in signal communication with the control unit (172) for providing a pressure signal proportional to the measure of the pressure inside said at least one storage compartment (110), wherein the control unit (172) is configured to control the operation of the refrigerating appliance (100) in function of said pressure signal received when said at least one fan (171) is in the first operative condition.

A smart refrigerator assembly includes a refrigerator to facilitate storage of perishable items. Each of a pair of carousels is rotatably integrated into the refrigerator to support perishable food items. Each of a pair of doors is hingedly coupled to the refrigerator for opening and closing the refrigerator. Each of the doors is constructed of an electrochromic material to facilitate the doors to be alternatively opaque or translucent. In this way the doors facilitate contents of the refrigerator to be visible without opening the doors.

Provided is a refrigerator. The refrigerator is characterized by enabling at least a part of a refrigerator door to be selectively transparent by a user's operation, such that the user sees through an inside of the refrigerator while the refrigerator door is closed.

A cooling package that includes a sensor that provides a signal to the user to indicate that the cooling package is ready for use and when the cooling package is depleted is described. The sensor and sensor display are selected on the basis of the freezing point of the contained solution. The freezing point of the solution is adjustable through use of organic or inorganic additives. The sensor can further be used by placement directly in contact with a food product and through measurement of temperature, pH or electrical conductivity a signal to the user through the built in display warns of food spoilage if the temperature, cumulative time above a pre-selected temperature, pH or electrical conductivity exceed a pre-selected limit.

An appliance, such as a refrigerator appliance, and controller configured to perform operations of a method for measuring contents in a container are provided. The operations include receiving, from a sensor, one or more signals indicative of a height of contents in a container, and determining a contents volume in the container based at least on the height of contents in the container.

Provided is a refrigerator. The refrigerator is characterized by enabling at least a part of a refrigerator door to be selectively transparent by a user's operation, such that the user sees through an inside of the refrigerator while the refrigerator door is closed.

A refrigerator includes a cabinet forming a storage space, a main door that opens and closes the storage space while defining an opening part that is in communication with the storage space, a sub-door mounted to the main door and configured to open and close the opening part, the sub-door including a panel assembly for allowing selective viewing of an inside of the opening part, the injection port is provided at a lower side of the sub-door to direct an insulating foaming solution to a space in the sub-door, a detection device for detecting an operation of a user, a lighting unit inside the refrigerator that turns on based on user operation to allow selective viewing of the inner side of the opening part, and a display unit inside the refrigerator at a position corresponding to the panel.

A modular humidity control system is provided. An example system includes a body configured for attachment with a food storage housing. The body may define a closed circuit air flow path for circulating air through the food storage housing. The system also includes a desiccant element secured within the closed circuit air flow path that removes moisture from the moisture-laden air passing through the closed circuit air flow path, and stores the removed moisture. The system further includes a regeneration system that monitors a saturation of the desiccant element. In an instance in which the saturation of the desiccant element exceeds a saturation threshold, the regeneration system may evaporate at least a portion of the moisture stored by the desiccant element.
