A refrigerator includes a cabinet, a control unit provided in the cabinet and controlling an operation of the refrigerator, a main door that opens or closes the cabinet and has an opening formed therein, a main hinge that couples the cabinet to the main door and allows the main door to be pivotably mounted, a sub-door that is formed on a front surface of the refrigerator and opens or closes the opening, a sub-hinge that couples the main door to the sub-door and allows the sub-door to be pivotably mounted, a sub-hinge cover that simultaneously shield a main hinge shaft of the main hinge and a sub-hinge shaft of the sub-hinge, and a wire disposed to extend from an inside of the sub-door, to be connected with the control unit, and to sequentially pass through the sub-hinge shaft and the main hinge shaft along an inside of the sub-hinge cover.

In one general aspect, the subject matter described in this specification can be embodied in a display case door that includes an insulated panel assembly that is transparent to visible light. The door further includes a door frame extending about and secured to a peripheral edge of the insulated panel assembly, an electronic display overlaying the insulated panel assembly, and at least one display retainer secured to the door frame and having a coupling end that mates with the electronic display to releasably secure the display to the door frame.

A refrigerated display cabinet of vertical or semi-vertical type has a containment structure defining a display compartment and an access opening, a main air inlet mouth and a main air outlet mouth being in communication with the display compartment. A channel connects the main air inlet and outlet mouths to direct a refrigerated air flow towards the main air inlet mouth in the form of an air curtain. The display compartment is divided into an upper area having one or more shelves and a lower area adapted to be loaded with products. One shelf separating the lower and upper areas is a blowing shelf having an internal conduit directing the refrigerated air flow in the display compartment through a secondary air-emitting mouth, a first deflector intercepting the refrigerated air flow which forms the air curtain and a second deflector intercepting the refrigerated air flow emitted by the blowing shelf.

A method for reducing sweating in a temperature-controlled display device includes receiving values of an ambient temperature, a door frame temperature, and relative humidity. The method can also include estimating a value of a dewpoint temperature using the values of the ambient temperature and the relative humidity. The method can also include determining control decisions for a door frame heater of the temperature-controlled display device using the value of the dewpoint temperature and the door frame temperature, and transitioning the door frame heater between an on-state and an off-state using the control decisions to maintain the value of the door frame temperature at or above the value of the dewpoint temperature.

An equipment monitoring system for a merchandiser. The system includes a control system that defines a data acquisition node, a server that is in remote communication with the control system via a network providing a communication bridge between the data acquisition node and the server, and that includes a database and one or more applications having executable processing instructions, and equipment monitoring sensors that are coupled to one or more components of the merchandiser to obtain status data regarding the status of the one or more components. The equipment monitoring sensors are in communication with the data acquisition node to communicate the status data to the server. The application(s) execute processing instructions that conduct program analysis for the one or more components using the status data based on information associated with the merchandiser to determine a predictive component failure associated with the one or more components.

A cooler includes a cabinet having an interior volume for storing a beverage container containing a beverage and a door for providing access to the interior volume of the cabinet. The cooler further includes a lock configured to maintain door in a closed position when the lock is engaged. The cooler includes a cooling unit configured to maintain the cabinet at a predetermined temperature and a temperature sensor arranged within the cabinet that detects a temperature within the cabinet. A control unit is in communication with the cooling unit and the temperature sensor, and the control unit is configured to control the cooling unit to maintain a temperature within the cabinet at a predetermined temperature as determined by the temperature sensor. The control unit may be configured to lock the door until a temperature within the cabinet is at the predetermined temperature.

A display case door includes a sealed glass unit assembly, a door frame, and an electronic display. The sealed glass unit assembly includes a sealed glass unit and a subframe extending about and coupled to the sealed glass unit. The subframe includes a set of two or more subframe rails configured to hold the sealed glass unit. The door frame is coupled to the subframe and configured to support the sealed glass unit assembly in the door frame. The electronic display is coupled to the door frame in front of the sealed glass unit. The door frame is configured to couple with a display case enclosure in an opening of the display case enclosure.

A door for a home appliance, a home appliance, and a method for manufacturing the same, are disclosed. The door for a home appliance comprises a panel assembly; and a frame assembly defining a predetermined space having an opening connected with an edge of the panel assembly, and making a foaming space for receiving a thermal insulator by means of the predetermined space of the frame assembly and the edge of the panel assembly, wherein a foaming injection hole through which the thermal insulator is injected is provided on at least one of ends of an upper surface, a lower surface, a left side and a right side of the frame assembly.

A transparent electronic display layer is placed between a front and rear transparent layer. A light guide is positioned behind the transparent electronic display layer and has an outer edge. Lighting elements are positioned adjacent to the outer edge. A cavity is positioned adjacent to and on an opposing side of the lighting elements as compared to the light guide such that light exiting the lighting elements enters both the light guide and the cavity. A graphic may be provided at the cavity.
