Abstract:
A refrigerator door has reinforcing corner brackets that structurally complete the comers of the door. The corner brackets are located at the door corners adjacent vertical and horizontal side walls of the outer door skin of the door. At least one reinforcing member such as a sheet or rectangular collar, or preferably reinforcing cross brace members are connected to the corner brackets. To achieve this connection and restrict heat transfer through the door and or adjacent the inner liner or in-turned flange of the outer door skin, the corner brackets have connecting tab portions that extend into the cavity of the door away from one of the side walls of the door and spaced from the other side wall of the door. The connecting tab portion is also spaced from the outer skin sheet and the inner door liner. As a result, the reinforcing member or members extend substantially across the width of the door spaced from the outer door skin wall and the inner door liner and are connected to the connecting bracket which is connected in heat transfer relation with side walls, horizontal or vertical, of the door. This reduces heat losses from the refrigerator cabinet conducted through the reinforcing member or members of the door.
Abstract:
A heat-insulated housing for use in a refrigerator etc. includes a housing body having a rectangular opening in one side thereof, the opening having four corners each of which is defined by two side plates generally perpendicular to each other, either one of the side plates being formed with a hole having an engagement open edge, a corner cover including two closing plates disposed to be perpendicular to each other so as to have a generally L-shaped section, the closing plates having backs thereof abutting against the side plates of the housing body respectively, an engagement protrusion formed on the back of either closing plate abutting against the side plate formed with the hole, the protrusion being inserted into the hole of the side plate and elastically deformable, and a plurality of engaging teeth formed on the protrusion so as to be aligned in a direction of insertion of the protrusion, one of the teeth elastically engaging the opening edge of the hole when the protrusion is inserted into the hole.
Abstract:
A shelf mounting support includes an annular flange portion having a side surface from which projects a cavity defining body portion. The mounting support is adapted to extend through an aperture formed in a liner of an appliance with the body portion of the mounting support being inserted in a respective aperture from an outer insulation zone side of the liner. Each mounting support is initially retained in the aperture through the use of an adhesive element that attaches the flange portion of the mounting support to the liner. Thereafter, the liner is positioned within an outer shell of the appliance and foamed insulation is then injected into the insulation zone and into the internal cavity of the mounting support to anchor the mounting support in position. To support a shelf, a plurality of mounting supports are arranged in a common plane upon which the shelf is adapted to rest.
Abstract:
Disclosed is a refrigerator comprising at least one chamber and a temperature adjuster adjusting an temperature inside the chamber, further comprising a first temperature sensor approximately sensing the temperature inside the chamber, a second temperature sensor spaced from the first temperature sensor so as to sense the real temperature inside the chamber; and a controller controlling the temperature adjuster according to the temperature sensed by the second temperature sensor when the temperature sensed by the first temperature sensor is within predetermined temperature limits of the chamber and the temperature sensed by the second temperature sensor is not. With this configuration, the temperature inside the chamber is effectively controlled by an accurate and prompt sensing operation. Though one of the first and second temperature sensors is abnormal, it is possible to replace or repair the abnormal temperature sensor, or to control the temperature adjuster by the other normal temperature sensor.
Abstract:
The present invention provides an insulated container that is especially useful in cooling and transporting thermally sensitive materials such as pharmaceuticals, organs, tissues and vaccines. In general, the present invention comprises a container having a base unit and a lid. The container is insulated, preferably through the use of vacuum insulation paneling. A tray holding specimens is placed within the insulated container along with a coolant. To affect the rate at which the coolant draws heat from the specimen within the tray, another competing heat source is placed within the container along with the specimen and coolant. In the preferred embodiment, the competing heat source comprises expanded polystyrene panels coating the inner surface of the insulated container.
Abstract:
A door for refrigerator which is sophisticated in design and provided at a lower production cost. The door for refrigerator is composed of a door panel made of metal and an inner plate combined with the door panel in a facing manner, a door cap which fits into the door panel and the inner panel in an upper portion, and a handle which fits into the door panel and the inner panel in a bottom portion. In addition to that, the door for refrigerator has a heat insulating form material injected inside. Then, the door for refrigerator is provided with draw forming at a position near to the edge of at least either side of the door panel.
Abstract:
A portable soft sided insulated container has an impermeable liner that provides a liquid holding barrier. The liner is folded from a single monolithic plastic sheet to reduce or eliminate the need for heat welded seams. The liner seats within the container and has a releasable attachment around its lip for mating with the rim of the container. The container has an insulated lid so that the entire assembly may be closed. The liner can be removed for cleaning, or replacement if punctured. When not in use the entire assembly can be folded into a collapsed position for storage. The container has two storage chambers that share a common insulated dividing wall.
Abstract:
A refrigerator cabinet has an exterior cabinet shell and a plastic liner insert defining a fresh food compartment and a freezer compartment where foamed in place insulation extends between the exterior cabinet shell and the interior liner. The liner has a partition with upper and lower walls extending rearwardly of a front mullion wall and between sidewalls of the liner. The upper sidewall has a cut-out recess adapted to receive an evaporator tray housing that is seated on edges of the upper wall of the partition. The tray supports an evaporator coil, motor, and fan. The tray has a cover that forms, together with the upper wall of the partition, the floor of the freezer compartment. By locating the evaporator tray recessed in the partition, in the partition space between the two compartments can be filled with rigid foam that extends between the upper and lower food compartments and to the exterior shell of the cabinet.
Abstract:
A refrigerated container, that can be economically manufactured in a variety of incrementally different sizes and shapes, is provided as well as are techniques for making those containers. The containers include an inner shell of fiber reinforced resin enclosing a space that is refrigerated by an evaporator coil arranged on the outer side of the shell. The coil is bonded to the shell, and a heat transmitting layer between evaporator coil turns is formed using a heat conducting adhesive material having metal granules dispersed in a resin base.
Abstract:
A getter system is provided for use with an evacuated container such as a vacuum insulation panel. The getter system has a first, activated getter material capable of gettering at least a first gas or vapor and a second, different gas or vapor. The getter system also has a second, activated getter material capable of gettering the first, but not the second, gas or vapor. Finally, the getter system includes packaging for the first and second getter materials, such that the first and second getter materials may be placed together within a single compartment of the evacuated container and the second getter material will be more readily exposed to the first gas or vapor than the first getter material. In this manner, the first getter material will be protected from the first gas or vapor even though it is already activated.
