The efficiency of a device for cooling or heating objects on a belt that moves through a path of a helix, in which gaseous cooling or heating medium is circulated within the device, is improved by positioning fans that circulate the cooling or heating medium so that the fans are distanced from the top of the helix.

A refrigerator includes an outer case. The refrigerator further includes an inner case that is located in the outer case and that defines a storage space. The refrigerator further includes a metal plate that is coupled to inner surfaces of an upper portion and both sides of the inner case and that includes a front end that is spaced apart from a front end of the inner case a first distance.

A refrigerator includes a top cover which separates a storage liner on a bottommost portion into a storage space located on an upper portion and a cooling space located on a lower portion. At least one return air hood is arranged at a front end of the top cover, the cooling space is jointly defined by the return air hood, the top cover and a bottom wall of the storage liner, and an evaporator is arranged in the cooling space. The return air hood includes a return air frame located on a front side and a return air rear cover inserted into the return air frame from an open rear end of the return air frame. The return air rear cover is arranged to separate a first opening formed in a front wall face of the return air frame into a first front return air inlet located on an upper portion and a second front return air inlet located on a lower portion, so that the visual attractiveness is achieved, and the fingers of children or foreign matter can be effectively prevented from entering the cooling space. In addition, due to two return air areas distributed vertically, return air can flow through the evaporator more evenly after entering the cooling space, the problem that a front end face of the evaporator is prone to frosting can be avoided to a certain degree, the heat exchange efficiency can be improved, the defrosting period can be prolonged, and energy conservation and high efficiency are achieved.

A blast cell system is provided with simple and scalable designs that prevent short cycling of air flow through any pallets in blast cells. The blast cell includes a plurality of suction channels that provide independent fluid pathways for directing the air drawn from different rows in the blast cell into the fan.

A refrigerator is provided. The refrigerator includes a refrigerator body, a door body and an ice making compartment. The refrigerator body includes a storage compartment. The door body is configured to open or dose the storage compartment. The ice making compartment is disposed in the storage compartment, and includes an ice making compartment shell, an ice maker, and an ice storage box. The ice maker is configured to make ice cubes. The ice storage box is located below the ice maker, and is configured to store the ice cubes made by the ice maker. The ice storage box includes a box body and a first ice baffle. At least a part of the first ice baffle is located in the box body, and the first ice baffle is configured to prevent the ice cubes from accumulating at a position of the box body close to the door body.

A refrigerator (100) having an air blower (102) located downstream of a transverse side of an evaporator (150) is provided. The refrigerator includes: a cabinet defining a cooling chamber (133) and at least one storage compartment, the evaporator (150) arranged in the cooling chamber (133), and the air blower (102) arranged on the transverse side of the evaporator (150) and located downstream of the evaporator (150) in an airflow path. The air blower (102) does not occupy a space behind or in front of the evaporator (150), which reduces a space occupied by the cooling chamber (133) in a front-rear direction, and ensures the thickness of a foamed material between the rear of the cooling chamber (133) and a housing of the cabinet.

A refrigerator (100) is provided. The refrigerator includes: a cabinet, in which are defined a cooling chamber (133) and at least one storage compartment; an evaporator (150), arranged in the cooling chamber (133) and configured to cool an airflow entering the cooling chamber (133) to form a cooled airflow; and an air blower (102), arranged on a transverse side of the evaporator (150), located upstream of the evaporator (150) in an airflow path, and configured to cause a return airflow in the at least one storage compartment to flow into the cooling chamber (133) to be cooled by the evaporator (150), and cause at least part of the cooled airflow to flow into the at least one storage compartment.

A refrigerator has an open front, an air curtain system having at least one upper air egress having an outer edge and at least one lower air-recovery ingress. The air curtain system is adapted to produce a substantially vertical air curtain over at least part of the open front of the refrigerator. The refrigerator has a plurality of shelves between the egress and the ingress a plurality of shelves between the egress and the ingress including a first shelf that has an aerofoil positioned in front of it, the first shelf being located in the upper half of the open front of refrigerator. The refrigerator also includes a second shelf that does not have an aerofoil positioned in front of it, the second shelf being located below the first shelf.

An ice maker for a domestic refrigeration device includes an ice-making tray having a plurality of freezing cavities which are divided between multiple cavity rows arranged one behind the other in a first tray extension direction. Freezing cavities arranged adjacent to one another in pairs in the first tray extension direction are separated on a tray underside of the ice-making tray by an indentation. The ice maker also includes a wall element for delimiting, in a freezing operating position of the wall element relative to the ice-making tray, a cold air channel between the underside of the ice-making tray and the wall element, which cold air channel extends substantially over the entire length of the ice-making tray in the first tray extension direction. The wall element is designed with at least one air-deflecting formation which projects locally into the cold air channel.

An ice maker and method of operation for a refrigeration appliance, the ice maker including an ice maker frame having an air inlet provided at a first end thereof. An ice tray is rotatably secured to the ice maker frame and configured to form ice pieces therein. An air handler includes an outlet diffuser having a central body defined by a first wall- and a radially spaced apart second wall, wherein a plurality of radially extending fins are disposed between the first and second walls. Each of the fins is spaced apart, one from the other, along an outer peripheral surface of the first wall. In an installed position, the outlet diffuser is disposed directly adjacent the air inlet at the first end of the ice maker frame. A method is provided for synchronizing an ice making cycle of an ice making unit and a defrost cycle of an evaporator.
