A cover is provided for a storage bin of a refrigerator. The cover includes a panel and a communication portion. The panel has an upper surface for storing food items thereon that is substantially planar and substantially horizontal. Moreover, the panel separates an upper space located above the panel from a lower space located below the panel. The communication portion is configured to provide fluid communication between the upper and lower spaces. In particular, the communication portion includes an upward-facing recessed surface, one or more side wall portions that extend above and at least partially bound the recessed surface, and a plurality of apertures that extend through the recessed surface and provide fluid communication between the upper space and lower space. The recessed surface and the one or more side wall portions collectively define a recess. Optionally, a wine rack is provided.

A muffler comprises a housing enclosed to form a hollow cavity, the cavity comprises a cylindrical chamber and a rectangular parallelepiped chamber, wherein one of bottom surfaces of the cylindrical chamber is connected with a first surface of the rectangular parallelepiped chamber, the cylindrical chamber communicates with an interior of the rectangular parallelepiped chamber, and the cylindrical chamber is provided with an air inlet and an air outlet.

A domestic refrigeration appliance has a separate storage area in an internal space into which foodstuffs, forming storage items, can be introduced. A liquid fluid can be introduced in the storage area independently of the internal space. For keeping the storage items fresh in the storage area a first operating mode and a storage mode, different therefrom, can be carried out. In the storage mode an aerosol mist generated by a misting device of the domestic refrigeration appliance is introduced as a fluid, and a misting rate of the aerosol mist during the storage mode is matched to a setpoint misting rate in dependence on at least one misting device-specific influencing parameter and/or a fluid-specific influencing parameter and/or a storage area-specific influencing parameter. There is also described a domestic refrigeration appliance.

A refrigerator appliance includes a storage compartment having a storage drawer assembly disposed therein. The storage drawer assembly includes a carrier drawer, a lid, and a bin that may be reversibly mounted in the carrier drawer in either a first orientation or in a second orientation. The bin defines a storage space for receiving food items. The bin includes a sealing wall that encloses the storage space in the first orientation. The bin defines an access opening that grants access to the storage space in the second orientation.

A ripening controldevice includes a holding unit, a desorption unit, and a supply unit. The holding unit holds a ripening component that is generated from an object and ripens the object. The desorption unit desorbs the ripening component held in the holding unit from the holding unit. The supply unit supplies the ripening component desorbed by the desorption unit into the target spaces (S).

A storage apparatus, comprising a compartment; and a box assembly, which is arranged in the compartment. The box assembly comprises: a first side wall; a second side wall arranged opposite the first side wall; a first conductive layer arranged on the second side wall; a first electret membrane, which is arranged on the first side wall, located between the first side wall and the first conductive layer and arranged parallel to the first conductive layer; and an adjusting component, which is used for adjusting the electric field intensity between the first conductive layer and the first electret membrane.

An inside air control apparatus includes: a gas supply device that performs a gas supply operation for supplying low oxygen concentration air into a container; and a controller that controls an operation of the gas supply device so that the inside air has desired composition. The controller is configured to be able to execute, if an oxygen concentration of the inside air is higher than a target oxygen concentration, a carbon dioxide concentration controlling operation for controlling composition of the inside air to be desired composition by causing the gas supply device to perform the gas supply operation, while allowing the gas supply device to change the amount of gas supply such that the carbon dioxide concentration of the inside air falls within a predetermined reference concentration range.

A refrigerated display case includes a housing surrounding multiple shelves. An air distribution gap is defined behind the shelves. An air return passage is defined below the shelves. A radial cross-flow fan is disposed in a fan region of the air return passage. The radial cross-flow fan includes an output connected to the air distribution gap. A primary cooling microchannel heat exchanger is disposed in the fan region downstream of the radial cross-flow fan such that air output from the radial cross-flow fan to the air distribution gap passes through the primary cooling microchannel heat exchanger. A pre-cooler microchannel heat exchanger is disposed upstream of the primary cooling microchannel heat exchanger.

A refrigerator includes a crisper drawer, a frame, and a cover plate. The frame is configured to receive the crisper drawer. The frame defines at least one orifice that is configured to vent air from the crisper drawer to an exterior of the crisper drawer to control a humidity within the crisper drawer. The cover plate is secured to the frame and is at least partially disposed over the at least one orifice. The cover plate is configured to pivot relative to the frame between a first position and a second position. The cover plate restricts air flow out of the crisper drawer in the first position. The cover plate facilitates air flow out of the crisper drawer in the second position.

An electret membrane, a preparation method, a refrigerator body assembly, and a refrigeration apparatus. The electret membrane includes: an electret material matrix; and a metal electrode, which is arranged on one side of the electret material matrix and is attached to the electret material matrix. The electret membrane can be electrically polarized insofar as the electret membrane is not externally connected to a power source, and can form an electrostatic field; and when the electret membrane is applied to a fresh keeping function of apparatuses, such as a refrigerator, the fresh-keeping structure of the electrostatic field can be simplified, thereby reducing the costs for generating the electrostatic field, and facilitating the realization of low-cost and high-reliability electrostatic field fresh keeping for fresh-keeping apparatuses, such as the refrigerator.
