The present invention discloses a refrigerator and a humidity control method for the same. The refrigerator comprises a humidity controller to controllably maintain moisture and/or perform humidification. The humidity controller is configured to: set a target humidity value, measure an actual relative humidity value of a target space, and calculate a target water replenishing mass W based on a difference between the two values and a current temperature of the target space; measure and calculate a water replenishing time T, and adjust the humidity controller so as to maintain its maximum humidifying rate V.sub.max within the time T to achieve the humidification purpose; and adjust the humidity controller so as to maintain a humidifying rate consistent with a water vapor loss rate in the target space to achieve the moisture maintaining purpose.

A system for controlling low temperature injury of cold-sensitive fruit vegetables by combining intelligent pre-cooling and segmented controlled atmosphere storage includes a sensor detection module, a data collection module, a wireless communications module, a terminal, and a control system, where the sensor detection module detects carbon dioxide, ethylene, and the temperature and the humidity within a fresh keeping chamber, then data is collected by using the data collection module connected to the sensor detection module, and then varying data is transmitted to the terminal by using the wireless communications module connected to the data collection module; the sensor detection module is connected to the control system; and after the terminal reads data detected by a sensor, an environment parameter is controlled by using the control system.

A meat aging chamber suitable for residential or portable use is provided. An aging apparatus comprises a refrigerated aging cabinet having a climate created by environmental apparatus. A server in a cloud resource communicates with a control circuit in the aging apparatus and with a portable interactive device. In a setup mode the portable interactive device communicates with a control circuit in the aging apparatus via a communications interface to identify the user to the control circuit. In an operating mode the communications interface enables communication between the cloud resource and the control circuit. A sensor module provides current values to the cloud resource for controlling operation in accordance with a software program embodying the aging protocol. The cloud resource can inform the smartphone of aging progress and alarm conditions. Physical features enable embodying the functions of a commercial aging chamber in a residential sized unit.

A household appliance includes a body or a carcass and a closing element, such as a door or a drawer, which is movably disposed on the body. A sensor unit is provided for measuring the temperature and/or the humidity. The sensor unit is at least partly disposed on the closing element.

A humidifier cools air in an air path that supplies the air to an internal space of a storage chamber such as a container or a warehouse, extracts water in a water extracting unit, stores the extracted water in a humidifying unit, and humidifies the internal space. The air path includes a main path that communicates with the internal space and a discharge path that discharges a part or all of water-extraction air to the outside of the target space, so that the humidifier can sufficiently humidify the internal space without receiving supply of water.

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 home appliance device, in particular a home appliance chiller device, such as a refrigerator, has an inner liner defining a storage space, a container arranged inside the storage space, a manual actuator configured for adjusting humidity inside the container, a receptacle at least partly accommodating the manual actuator, and a frame which is arranged inside the storage space and to which the receptacle is fixed.

A home appliance device, in particular a home appliance chiller device with improved versatility, includes an inner liner defining a storage space, a container disposed inside the storage space, a manual actuator configured for adjusting humidity inside the container, an illumination unit configured for illuminating an interior of the container and a receptacle at least partly accommodating the manual actuator and the illumination unit. A home appliance, in particular a home chiller appliance including a home appliance device, is also provided.

A domestic appliance includes at least one PEF unit having at least one pair of electrodes and a network part for supplying the electrodes with an operating voltage. The operating voltage is of a suitable magnitude to expose material in a space between the electrodes to an electrical field having a field strength of at least 500 V/mm, and the duration of the exposure is short enough to avoid a breakdown. A water pipe extends through the space. A spacing between the electrodes is a maximum of 3 mm.

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.
