The present invention provides a refrigeration and freezing device, including a case body, a door body, an oxygen-enrichment membrane assembly, an air pump, and a refrigeration system. For the refrigeration and freezing device, temperature within an appropriate storage range and a nitrogen-rich and oxygen-deficient atmosphere cooperate, thereby effectively extending the shelf life of foods.

An air-regulating freshness-preserving storage device comprises a container having a first storage space defined therein; and an oxygen removal device configured to remove a part or all of oxygen in air in the first storage space, so as to obtain the air rich in nitrogen, low in oxygen, and favorable for food preservation.

The present invention provides a storage device, including: a box body, a gas separator, and a gas extraction device, wherein the gas extraction device is communicated with the gas separator. The storage device of the present invention may form a nitrogen-rich and oxygen-deficient atmosphere beneficial to food freshness preservation.

An air separation device and a refrigerating and freezing device. The air separation device comprises a support frame and an air separation membrane, wherein a supporting surface with a channel and an enriched-gas collection chamber communicated with the channel are formed in the support frame. The air separation membrane laid on the support surface of the support frame and configured to enable more of a specific gas than other gases in airflow of the space around the air separation device to enter the enriched-gas collection chamber through the air separation membrane. According to the air separation device provided by the present invention, the support frame is specially designed to adopt the structure provided with the support surface and the enriched-gas collection chamber, the channel communicated with the enriched-gas collection chamber is formed on the support surface, and the air separation membrane is disposed on the support surface.

A refrigeration appliance includes a storage area for refrigerated goods and a control facility or unit for controlling a storage climate in the storage area by using storage climate parameters. One storage climate parameter is a temperature in the storage area. Another storage climate parameter relates to an air speed in the storage area. The refrigeration appliance is used in particular for the dry curing of meat.

Disclosed is a freshness preservation unit for a storage box of a refrigerator. At least one through hole is provided on at least one box wall of the storage box. The freshness preservation unit includes a housing wherein an accommodating space is formed. A freshness preservation film is provided in the accommodating space. The housing is provided with a fixing piece which is cooperatable with the box wall of the storage box such that the freshness preservation unit is assembled in the through hole of the storage box in a detachable manner. The freshness preservation unit realizes the functions of freshness preservation and storage for fruits and vegetables, and is assembled in the through hole of the storage box in a detachable manner, convenient to assembly and disassembly, convenient to cleaning and replacement, and low in the maintenance cost.

An appliance air freshener having a frame and an air freshener medium. The frame defines an enclosure having a first face, and a second face opposite and spaced from the first face. The first face and the second face form an outer perimeter of the enclosure. The frame also defines a passage located within and spaced from the outer perimeter and extending along a passage axis from the first face to the second face. The air freshener medium is located within the enclosure.

The invention relates to a refrigeration appliance, in particular a refrigerator or a fridge-freezer (2). The refrigeration appliance comprises a housing (4), a refrigerating compartment (6) formed within the housing (4), a slidably and releasably supported first drawer (20a) having a first vertical extension, a second slidably and releasably supported second drawer (20b) having a second vertical extension being greater than the first vertical extension of the first drawer (20a), and a first, a second and a third drawer support position (72a, 72b, 74a, 74b, 76a, 76b), wherein in vertical direction the first drawer support position (72a, 72b) is higher than the second drawer support position (74a, 74b) and the second drawer support position (74a, 74b) is higher than the third drawer support position (76a, 76b). When A) the first or second drawer (20a, 20b) is supported at the first drawer support position (72b) the upper levels of the first and second drawers (20a, 20b) are at the same vertical position within the refrigerating compartment (6), and when the first drawer (20a) is supported at the third drawer support position (76b) or when the second drawer (20b) is supported at the second drawer support position (74b) the lower levels of the first and second drawers (20a, 20b) are at the same vertical position within the refrigerating compartment (6), or when B) the first or second drawer (20a, 20b) is supported at the third drawer support position (76a) the upper levels of the first and second drawers (20a, 20b) are at the same vertical position within the refrigerating compartment (6), and when the first drawer (20a) is supported at the second drawer support position (74a) or when the second drawer (20b) is supported at the first drawer support position (72a) the lower levels of the first and second drawers (20a, 20b) are at the same vertical position within the refrigerating compartment (6).

The present invention refers to a temperature control module for a delivery box cabinet. According to the present invention, the various components of the temperature control module are provided in a compact block-like manner. The temperature control module is formed self-contained such that it can be installed in a modular manner as a temperature control module in the delivery box cabinet besides delivery compartments of the delivery box cabinet. Thus, a quite efficient but still compact overall configuration can be achieved. Furthermore, the present invention refers to a delivery box cabinet provided with such a temperature control module or at least being provided to be supplemented by such a temperature control module.
