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 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 movable controlled atmosphere store for fruits and vegetables, including: a store body in rectangular container structure and successively provided with an equipment room and a storage room along length direction; the equipment room is provided with an equipment door respectively on left and right sides; the storage room is in thermal insulation and sealing structure and provided with a sealing door at an end far away from the equipment room, and is provided with a sampling door on a side which is provided with a sealing film connected around a frame thereof, and a sampling assembly connected with the sealing film in cylindrical structure; a controlled atmosphere control system, including a control panel, as well as a refrigerator, a humidifier, a sterilizer, a nitrogen generator, a carbon dioxide adsorber, an ethylene adsorber, a temperature and humidity sensor and a gas concentration sensing device connected with the control panel.

A refrigerating and freezing device, the refrigerating and freezing device including: a casing, including an inner container, a housing, and a heat preservation layer, wherein a storage space is disposed in the inner container, a storage container is disposed in the storage space, and the storage container has a controlled atmosphere fresh-keeping space therein; and a controlled atmosphere membrane component, configured to allow more oxygen gas in an airflow in a space around the controlled atmosphere membrane component than nitrogen gas in the airflow in the space around the controlled atmosphere membrane component to pass through a controlled atmosphere membrane to enter an oxygen gas-enriched collecting cavity. The storage space is composed of a top cover and a bottom box, a lower surface of the top cover is provided with a concave cavity, and the controlled atmosphere membrane component is disposed in the concave cavity.

A method for monitoring a drawer interior of a vacuum drawer device when the lid is supported by the drawer airtight and closed, includes: periodic measurement of the relative humidity with a humidity sensor arranged in the path of a dehumidifying channel in the lid or, respectively, the drawer interior; comparison of the measured relative humidity with an upper threshold; and as soon as the measured relative humidity is above the upper threshold, opening the valve and inducting a ventilator arranged in a recess or in the path of a dehumidifying channel in the lid. Fresh air is sucked through an air inlet opening, circulated, and thereafter released again from the dehumidifying channel and the drawer interior communicating therewith, until the relative humidity reaches a lower threshold measured by the humidity sensor. Then the valve is closed, the ventilator is stopped, and the controller switches into the humidity monitoring mode.

A refrigerator includes a drawer in a refrigeration compartment including a support on a wall of the compartment, and a work slot oblique to a lid. The lid opens or closes the drawer and includes a protruding portion on an upper surface and a motion member on a side edge of the lid moving in the work slot. A motor module includes a cam and a motor driving the cam in first rotation, to push the protruding portion to drive the motion member to move obliquely upward along the work slot, so the lid ascends to a first position, and driving the cam in second rotation opposite the first to cause the lid to drive the motion member under gravity obliquely downward along the work slot, so the lid descends to a second position lower than the first in automatically adjustment. A method for lid adjustment is also provided.

A modular humidity control system is provided. An example system includes a body configured for attachment with a food storage housing. The body may define a closed circuit air flow path for circulating air through the food storage housing. The system also includes a desiccant element secured within the closed circuit air flow path that removes moisture from the moisture-laden air passing through the closed circuit air flow path, and stores the removed moisture. The system further includes a regeneration system that monitors a saturation of the desiccant element. In an instance in which the saturation of the desiccant element exceeds a saturation threshold, the regeneration system may evaporate at least a portion of the moisture stored by the desiccant element.

To provide a cooling device that can refrigerate foods and stably maintain high humidity without being limited by a region and a period. A cooling device includes a heat exchange unit that performs heat exchange between a refrigerant circulating in a freezer and air circulating in a box and an adjusting unit that maintains a state in which moisture adheres to heat transfer units of the heat exchange unit.

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 positive and negative pressure system and an operation method therefor, and a positive and negative pressure electrical appliance using the positive and negative pressure system. The positive and negative pressure electrical appliance comprises: a positive and negative pressure refrigerator, a positive and negative pressure washing machine, a vacuum dishwasher/fruit and vegetable cleaning machine, a super-oxygenated water washing range hood, a positive and negative pressure oven/fryer/microwave oven, a positive and negative pressure fresh-keeping compartment, a positive and negative pressure fresh-keeping warehouse, and a positive and negative pressure modular cabinet. Regulating airflow with positive and negative pressure, or carrying multiple effective loads such as ozone, an air catalyst, a negative ion, modified atmosphere gas and water for orderly getting in and out of or staying in a positive and negative pressure chamber, and exerting the required effects on objects therein.
