A pesticide residue removal device for a refrigerator, and a refrigerator are provided. The pesticide residue removal device includes: an ozone generator configured to generate ozone; an ozone water container configured to store water therein, where the ozone water container communicates with the ozone generator, so that ozone is dissolved into water of the ozone water container to obtain ozone water; and an atomizer communicating to the ozone water container, receiving and atomizing the ozone water, and supplying the ozone water to a storage space of the refrigerator. The generated ozone water is atomized to fully fill the entire storage compartment of the refrigerator to achieve effective pesticide residue removal and sterilization; ozone water can be prepared on demand to reduce waste; and people are well prevented from getting harmed at an excessive ozone concentration.

Provided in the present application are an air duct system and a refrigeration appliance provided having the same. The air duct system comprises a drying system and a cooling system arranged in cooperation with each other, the cooling system has an evaporator and an air return port and an air supply port arranged on the two sides of the evaporator, and the drying system is disposed between the air return port and the evaporator, and comprises an air compressor and an air storage tank connected to each other; the air discharged by the air return port passes in sequence through the air compressor and the air storage tank and then flows to the evaporator, so that the air passing through the evaporator is dried, avoiding the problems of frosting and low efficiency.

A refrigerator appliance includes a cabinet with a fresh food chamber, a freezer chamber, and an aging chamber each defined in the cabinet. The refrigerator appliance also includes an aging chamber door mounted to the cabinet and movable between a closed position and an open position. A method of operating the refrigerator appliance includes receiving a meat aging input from a user interface of the refrigerator appliance and moving a lock configured to retain the aging chamber door in the closed position to a locked position whereby the aging chamber door is retained in the closed position in response to the meat aging input. The method also includes activating a dedicated humidity control system in fluid communication with the aging chamber and fluidly isolated from the fresh food chamber and the freezer chamber for an aging time after moving the lock to the locked position.

A delivery robot loading box state management system includes a loading box provided in a delivery robot such that a delivery product is loaded therein; a sensing unit capable of detecting the state of the inside of the loading box; a temperature control unit capable of adjusting the temperature inside the loading box; a deodorizing unit for removing odors inside the loading box; and a control unit for controlling the operation of at least one of the temperature control unit or the deodorizing unit according to the detection result of the sensing 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 refrigerator may include a cabinet, and a drawer provided with a front panel and a storage bin provided at a rear of the front panel, the front panel being provided so that the open front portion of the storage chamber is opened and closed, and the storage bin being received in a storage chamber. The refrigerator may also include a deodorizing case including an upper end part provided on an inner surface of the storage bin, and a lower end part provided on an outer surface of the storage bin. Additionally, a deodorizing member provided in an inner part of the deodorizing case to remove an odor of the storage chamber.

A first heat exchanger, a desiccant block, and a second heat exchanger are arranged in series. In a dehumidifying operation, a first operation mode and a second operation mode are alternately repeated. In the first operation mode, the first heat exchanger is operated as a condensor or a radiator and the second heat exchanger is operated as an evaporator. In the second operation mode, the first heat exchanger is operated as the evaporator and the second heat exchanger is operated as the condensor or radiator. A pressure reducing amount in the first operation mode is controlled to be smaller than in the second operation mode so that a degree of superheat in the evaporator (second heat exchanger in the first operation mode, first heat exchanger in the second operation mode) in each of the first operation mode and the second operation mode is appropriately controlled to increase a dehumidifying amount.

Voltage application device includes voltage application circuit. Voltage application circuit applies a voltage to load including discharge electrode that holds liquid, voltage application circuit generating discharge in discharge electrode. During a drive period, voltage application circuit periodically changes a magnitude of the voltage applied to load at a drive frequency within a predetermined range including a resonance frequency of liquid, voltage application circuit mechanically vibrating liquid.

An oxygen removal module, a fresh-keeping device and a refrigerator. The oxygen removal module comprises: an electrolyte tank provided with a water inlet; and a water tank provided with a water outlet, the water outlet being connected to the water inlet through a first pipeline, to supplement water to the electrolyte tank by means of the water tank.

A fresh-keeping device for a refrigerator, and a refrigerator. The fresh-keeping device includes a fresh-keeping box body having a lower frame and an upper frame, the lower frame being provided with an accommodating space as well as an opening and a gas inlet communicated with the accommodating space, the upper frame being provided with a refrigerating air channel, and the refrigerating air channel being used for refrigerating the accommodating space; a drawer is configured to enter from the opening and accommodated in the accommodating space to fit the fresh-keeping box body to form the sealed accommodating space; and a nitrogen generating means connected to the side of the fresh-keeping box body on which the gas inlet is formed and is configured to charge generated nitrogen into the accommodating space from the gas inlet.
