A refrigerator includes a rear assembly panel coupled with an assembly cover panel that includes at least one vent. At least one circulation fan is positioned between the rear assembly panel and the assembly cover panel and is proximate the at least one vent. A filter is positioned between the rear assembly panel and the assembly cover panel and is coupled to a photocatalyst to form an activated carbon filter. A light-emitting diode (LED) panel assembly includes a plurality of LEDs positioned on the rear assembly panel and is positioned to project light on the activated carbon filter. An air circulation path extends through the at least one vent and the activated carbon filter and is configured to direct air along the air circulation path, and the activated carbon filter is configured to filter airborne bacteria and particulate matter from the air as the air passes through the activated carbon filter.

A volatilization device and a storage device. The volatilization device comprises: a shell having a cavity, an air outlet communicated with the cavity being formed on the shell; and a color change member fixed on the shell. One side of the color change member is exposed to the cavity, the other side of the color change member can be seen from the outer wall of the shell, and the color change member changes color according to the concentration of a target gas in the cavity. The storage device comprises a box and the volatilization device, and the shell is fixed in the box. The color change member is fixed on the shell, one side of the color change member is exposed to the cavity of the shell, the other side of the color change member can be seen from the outer wall of the shell, and a user thus can determine, by observing the color change of the color change member, the validity of an item to be stored in the cavity, helping the user in in-time replacing.

Disclosed is a refrigerator provided with a sealed drawer on a door body. The refrigerator comprises: a refrigerator body, which defines a first storage space; a first door, which is pivotally arranged at a front portion of the refrigerator body and configured to open or close the first storage space; a sealed barrel, which is arranged in the first door and forms an opening at the side away from the first storage space; a drawable box arranged in the sealed barrel in a drawable manner via the opening; and a ventilating device, which is arranged in the sealed barrel and configured to allow communication between an internal space of the sealed barrel and the first storage space when turned on, thus realizing air exchange between the internal space of the sealed barrel and the first storage space.

The present invention provides a storage device, including: a box body, a gas separator, and a gas extractor, wherein the gas extractor 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 improved system and method for treating, precooling, handling, and packaging perishable products uses a mobile container enhanced with increased capacity refrigeration and air flow to recirculate functional substances including sanitizers, and ripening management and conditioning agents across the surface of perishable products during the precooling step. The mobile container is a prefabricated container or is modified from a standard intermodal container or over-the-road semi-trailer. The enhanced forced air and/or refrigeration equipment is contained within the container and/or mounted on the top and/or side exterior of the container and can accomplish rapid cooling. The mobile container can be located near harvest or facilities with no cooling assets. A combined system using conveyors and operational controls provides automated handling of the perishables from receiving, through precooling and treatment, through processing and packaging, preferably to a MAP process, and then to distribution.

A refrigerator appliance includes a storage compartment having a crisper assembly disposed therein. The crisper assembly includes a drawer, a lid, and a shelf. The lid is fixed to the storage compartment and remains stationary therewith. The drawer and the shelf are each configured to be extended or retracted relative to the storage compartment and are provided in a stacked arrangement. The lid seals the drawer when the drawer is in the retracted position.

A crisper drawer for a refrigerator having a refrigerated compartment is disclosed. The crisper drawer includes a plurality of side walls defining a storage chamber, an opening in a side wall to provide fluid communication between the storage chamber and the refrigerated compartment, and a multi-function filter cassette configured to be positioned within the opening. The multi-function filter cassette includes a first filter configured to remove contaminants from a first air flow within the refrigerated compartment, a second filter configured to remove contaminants and/or moisture from a second air flow within the storage chamber, and a central wall configured to prevent fluid communication between the refrigerated compartment and the storage chamber.

A vehicle and a system and method of operating the vehicle based on a gesture made by a traffic director. The system includes a camera and at least one neural network. The camera obtains an image of a flag operator. The at least one neural network is to generates an encoded hand vector based on a configuration of a hand of the traffic director from the image, combines a skeleton of the traffic director generated from the image and the encoded hand vector to generate a representation vector, and predicts a gesture of the traffic director from the representation vector.

Disclosed is an oxygen-control freshness preservation refrigerator, comprising a cabinet with a refrigerating compartment and a freezing compartment. A partition plate for separating the refrigerating compartment from the freezing compartment is arranged in the cabinet. The refrigerator further has a freshness preservation compartment arranged inside the refrigerating compartment and an oxygen control device for reducing the oxygen content inside the freshness preservation compartment, the oxygen control device comprises a gas-regulating membrane assembly and a gas extraction assembly. The gas-regulating membrane assembly has at least one gas-regulating membrane for selective gas permeation. The gas extraction assembly has a gas extraction pump arranged in the partition plate; and the gas extraction pump is provided with a gas intake pipe in communication with a gas discharge side of the gas-regulating membrane, and a gas discharge pipe for discharging gas from the gas discharge side of the gas-regulating membrane.

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.
