A wine cooler capable of reducing power consumption, including a cooler body, where a temperature adjustment device is disposed inside the cooler body, at least one cooler door is disposed on a front side of the cooler body, a plurality of locking components are disposed around edges of the cooler door, a heat insulating element used for preventing heat inside the cooler body from being dissipated to outside the cooler body is correspondingly disposed on an inner side and/or an outer side of each cooler door, and the cooler door is detachably fastened to the heat insulating element as a whole by using the plurality of locking components. The heat insulating element effectively isolates the heat inside the cooler body and prevents the heat inside the cooler body from being dissipated to outside of the cooler body through the cooler door.

A refrigerator includes a receiving chamber and a drawer movably received in the receiving chamber. The drawer is at a first location when it is closed. The refrigerator further includes a first sensor that is fixed to the drawer or a wall of the receiving chamber. The first sensor is configured to detect when the drawer reaches a second location. The first and second locations are spaced apart by a spacing distance.

A refrigeration bin is disclosed. The bin includes a product display area defined by four side walls, a floor, and an access opening. Also included are an air supply vent on each of a first opposing set of the side walls, and an air return vent near each of a second opposing set of the side walls, in which the second opposing set of the side walls are adjacent to the first opposing set of the side walls. There is a return air duct, a first end of the return air duct in air flow communication with the air return vent, and a supply air duct, the first end of the supply air duct in air flow communication with the air supply vent, allows air flow in the display area. A cooling device is included for cooling air before it enters the supply air duct. The refrigeration bin can be useful to showcase foodstuffs in grocery stores and the like.

A refrigerator including a main body having a plurality of storage compartments to store food; a door configured to open and close the main body; a door switch configured to detect an opening and closing of the door; a microphone configured to receive a voice of a user; and a controller configured to recognize the voice of the user input from the microphone and extract shopping goods information, wherein the controller extracts the shopping goods information based on the voice of the user input through the microphone when the door is opened.

A refrigerator of this embodiment includes a housing that includes a storeroom, a door that is rotatably provided in the housing through a hinge portion and opens or closes an opening of the storeroom by the rotation, a connection line that is led out to the vicinity of the hinge portion, and a wireless communication apparatus that includes a wireless communication unit and is connected to the connection line.

A refrigerator includes a receiving chamber and a drawer movably received in the receiving chamber. The drawer is at a first location when it is closed. The refrigerator further includes a first sensor that is fixed to the drawer or a wall of the receiving chamber. The first sensor is configured to detect when the drawer reaches a second location. The first and second locations are spaced apart by a spacing distance.

A cooling unit comprising: an interior space; a door separating the interior space from air external to the cooling unit, wherein the door comprises a transparent window; an air curtain system having an air egress and an air-recovery ingress, wherein the air curtain system produces an air curtain between the air egress and the air-recovery ingress, the air curtain being within the interior space and spaced from the door; and an air curtain guide for guiding flow of air within the air curtain, wherein the air curtain guide is within the interior space. A method of reducing condensation on a transparent window in a door of a cooling unit is also provided.

A refrigeration device includes a storage area which is delimited by a body and a door and which is subdivided by a shelf into an upper and a lower compartment. A drawer is accommodated in the lower compartment. In a stop position of the drawer in which it is pushed into the lower compartment, a front wall of the drawer bears against a front edge of the shelf. A closure element can be moved across a passage or opening in the shelf between a position which blocks the passage and a position which opens the passage over at least part of its cross section.

The present disclosure relates to a cryocooling system and method. The system includes a sample well and a sample chamber, each of which having an interior that is sized and shaped to hold a cryocooling gas at cryogenic temperatures and a pressure below 1 atm. The sample chamber is also sized and shaped to hold a sample substance to be cryocooled. An impedance tube connects the interior of the sample well to the interior of the sample chamber to allow cryocooling gas to move from the sample well to the sample chamber. A vacuum tube is connected to the interior of the sample chamber on one side and to a vacuum pump via a vacuum port on the other. The vacuum tube is sized and shaped to allow cryocooling gas within the sample chamber to be pumped out of the sample chamber by the vacuum pump.
