A refrigerator includes a rear wall, a first strap, a second strap, an insulative member, a housing, an ozone generator, a ventilation panel, and a light. The first strap and the second strap fix the insulative member to the rear wall. The housing is disposed in the ventilation panel. A frontside of the housing has a recessed portion that defines a receptacle on a backside of the wall, a trough on the frontside of the wall, and a first number of vents. The first number of vents establish fluid communication between the receptacle and the trough. The ozone generator is disposed in the receptacle. The light is fixed to the housing. The light includes a cover that overlaps at least a portion of the trough and defines a second number of vents that are in fluid communication with the trough.

An ozone generator for producing ozone water for the sanitation and disinfection of an ice maker includes cathode plates and anode plates that are arranged alternatively in an electrolysis chamber. The cathode plates and the anode plates are connected to a cathode wire and an anode wire of a cable. A wiring chamber is provided with a temperature sensor extending into the electrolysis chamber and connected with a temperature sensor wire of the cable. The cable is connected to a control circuit. The ozone generator is submerged in the ice-making water of the ice-making water tank. The temperature sensor of the ozone generator submerged in the ice-making water is configured to sense temperature changes. When the ice maker is activated, the temperature of the ice-making water in the ice-making water tank will drop. When the temperature drops to the set temperature, the ozone generator is activated once to produce ozone gas. The ozone gas is dissolved in the ice-making water to generate ozone water. The ozone water is used to sanitize the ice-making loop process of the ice maker. The ozone generator has simple structure, low cost and good effect.

A refrigerator includes a storage compartment and an air sanitation device mounted on a top wall of the storage compartment. The air sanitation device includes: a housing having an upper wall, a lower wall, and a peripheral wall connecting the upper wall to the lower wall; an air channel disposed in the housing and has an air inlet and an air outlet; a fan disposed in the air channel to force air to enter the air channel from the air inlet and leave the air channel from the air outlet; and an air detection device and/or an air purification device disposed in the air channel. The air outlet is disposed on the peripheral wall, and the air channel is configured in such a way that the air is discharged out of the air outlet obliquely downward.

A refrigerator includes a rear wall, a first strap, a second strap, an insulative member, a housing, an ozone generator, a ventilation panel, and a light. The first strap and the second strap fix the insulative member to the rear wall. The housing is disposed in the ventilation panel. A frontside of the housing has a recessed portion that defines a receptacle on a backside of the wall, a trough on the frontside of the wall, and a first number of vents. The first number of vents establish fluid communication between the receptacle and the trough. The ozone generator is disposed in the receptacle. The light is fixed to the housing. The light includes a cover that overlaps at least a portion of the trough and defines a second number of vents that are in fluid communication with the trough.

A fixation system for use in a refrigerator, including an insulative member and a ventilation panel defining a number of vents, includes first and second straps. The second strap is spaced apart from the first strap. The first strap and the second strap are collectively configured to receive the insulative member. The first strap includes a main body having a rear side and a front side opposing the rear side. The rear side is configured to lie against a rear wall of the refrigerator and defines a first aperture configured to receive a first fastener to fix the main body to the rear wall of the refrigerator. The front side defines a second aperture configured to receive a second fastener to fix the ventilation panel to the main body.

An AC electric field-assisted refrigerating container comprises: an outer container casing made of metal and having a storage chamber thereinside; an inner container casing formed of a dielectric panel and disposed inside the outer container casing; cooling means to cool an inside of the storage chamber; a plurality of insulated electrodes each formed by densely covering an entire circumference of an electrode plate with an insulator and disposed on an inner wall of the inner container casing; and a transformer for supplying an AC of 10 to 20 VA, at a voltage of 2000 to 4000 V and a frequency of 50 to 60 Hz, wherein the transformer has a ground terminal; wherein the refrigerating container is configured to cause AC discharge from the insulated electrodes to form an AC electric field inside the storage chamber, wherein, as a result of the AC discharge, electrons are supplied to the inner container casing formed of the dielectric panel, and then flow throughout the inner container casing, thereby allowing the electric field to be uniformly distributed throughout the inside of the storage chamber, while being maintained in terms of intensity thereof and, wherein the dielectric panel is a woody panel.

A device and method for securely delivering a package are provided. The device may be a container for receiving packages, and may include a body configured to receive a package, a door coupled to the body and having a locking mechanism configured to prevent the door from opening when engaged, a controller configured to receive a signal corresponding to the package, and to unlock the locking mechanism in response to the signal, and a sanitization device configured to sanitize at least one of the package and contents of the package by emitting at least one of a gas and a light configured to kill one or more of bacteria, viruses, and other pathogens. The method for securely delivering a package may include storing information corresponding to the package in a memory of the container, receiving a signal indicating that the package is ready for delivery to the container, unlocking a locking mechanism of the container in response to receiving the signal, and activating a sanitization device to sanitize the package after the package has been placed inside the container.

An apparatus is provided for preservation of fresh items or produce. The apparatus comprises a closed housing (1) to enable an environment within the housing to be controlled, a shelf (3) within the housing (1) for supporting fresh items, an ozone generator (10), a humidifier (8) and a propagation or distribution system (24, 17). The propagation or distribution system (24, 17) is configured to transfer ozone generated by the ozone generator (10) and water particles produced by the humidifier (8) separately to the vicinity of the shelf (3) before releasing both the ozone and water particles into the housing (1).

A refrigeration appliance comprises a cavity in which an ozone generating device is placed. The ozone generating device is configured to maintain in the cavity a concentration of ozone between 0.04 and 0.12 ppm, more preferably between 0.06 and 0.1 ppm.

A high-humidity and ozonated air storage system can inhibit mold growth in mass foodstuff storage while also preventing dehydration loss. The present system and method can operate at a higher humidity and temperature than conventional methods and allows for antimicrobial ozone treatment to be applied to foodstuffs in via a storage environment. In some embodiments, humidity can be controlled so that it is approximately equal to the moisture content of produce stored within a main storage area. In such embodiments, this can mitigate water loss from the produce via osmosis to the environment.
