A chest freezer plunge power safety system is configured to prevent any chance of electrical shock by disconnecting power to the chest freezer when the freezer door is opened. Chest freezers are often filled with water that is chilled by the freezer and used for cold plunge therapy. A person will open the freezer door and submerge their body or portion of their body in the cold water. One or more sensors are configured to detect when the freezer door is opened. The sensor or sensors are coupled with a contactor that disconnects power from a power source to the chest freezer. The sensor element may be attached to the freezer door and configured to be detected by the sensor when the freezer door is in a closed position. The sensor may be coupled with a controller that controls the function of the contactor to open or close the circuit.

A floating cooler device is provided. The device is comprised of a cooler with a buoyant body. The device is also comprised of a waterproof storage area to safely store electronic devices and other valuables. In addition, the device may be comprised of a solar panel that powers at least one charging port within the waterproof storage area that can be used to charge electronic devices.

A household appliance includes a casing, including an interior cavity, and a door, at least one electrical device which is arranged in/on the door, a control unit which is arranged in/on the casing and is configured to control the electrical device, a first wireless power transfer and data transceiver arrangement, which is arranged in/on said casing and configured to be electrically connected to the control unit via first USB electrical connection circuitry, and a second wireless power transfer and data transceiver arrangement, which is arranged in/on the door and configured to be electrically connected to the at least one electrical device via second USB electrical connection circuitry. The first and second wireless power transfer and data transceiver arrangements are arranged to wirelessly exchange data and wirelessly transfer electric power for the electrical device.

A universal modular accessory and ice pack integration system for coolers and insulated storage containers, designed to enhance thermal performance, internal organization, and cargo stability. The system incorporates channels or compartments for securing reusable ice packs, which may be telescopically mounted or retained along interior surfaces. A variety of accessoriesincluding stackable beverage holders, storage bins, knife scabbards, and ice binsare removably attachable via one of four distinct mechanisms: (1) T-shaped channel engagement; (2) dovetail channel engagement; (3) magnetic attachment to embedded ferromagnetic panels; and (4) retrofit fixtures enabling compatibility with non-integrated coolers. Accessories are modular and space-efficient, providing structured storage that prevents destructive shifting or damage to contents during transport. Attachment surfaces are positioned throughout the cooler, including the lid. The system minimizes melting ice waste, enhances storage utility, and supports secure, reconfigurable organization in demanding environments, while also offering ecological benefits through its reusable design.

A modular cooler assembly having a plurality of cooler or other storage components, which may or may not be insulated, each component defining an interior storage space and an exterior surface and at least one connector configured to removably interconnect adjacent cooler components, wherein the connector includes a first engagement portion attached to a first cooler component and a second engagement portion attached to a second cooler component wherein the plurality of cooler components are configured to be arranged in multiple configurations based on user preference while maintaining thermal insulation of the interior storage space of each cooler component.

The present disclosure provides systems and methods for a food storage system including a freezer, a temporary storage unit removably coupled with the freezer, and a freezer management application. The freezer includes two or more independently controllable climate zones which can be automatically adjust based on data received from sensors and cameras in each of the climate zones or manually adjust using the freezer management application. The freezer is also configured to receive one or more modular inserts for increased customization and functionality. The temporary storage unit includes a climate zone that is configured to be controlled and regulated by the freezer when the temporary storage unit is coupled with the freezer. Based on the data received from the sensors and cameras, the freezer management application generates alerts regarding deviations in the conditions of the climate zones or conditions of food items stored in the system.

A battery-powered portable cooler includes a main body with a tub for receiving contents, a cooling compartment, and insulation at least partly surrounding the tub. A lid opens and closes to selectively provide access to the tub. A wheel supports the main body on a support surface. A refrigeration system includes a compressor, a condenser, and an expansion valve, all located in the cooling compartment, and an evaporator including evaporator coils at least partly surrounding the tub to conductively cool the contents of the tub. An electronic control unit is operably connected to a user interface to receive input from the user interface and control operation of the refrigeration system. A battery pack mates with a battery receptacle along a battery insertion axis in a direction toward the tub. The battery pack provides electrical power to the electronic control unit, the user interface, and the refrigeration system.

A magnetic field fresh-keeping apparatus includes a drawer container, a drawer, a magnetic field assembly, an air inlet duct assembly, and an air return opening. An opening is provided at the front side of the drawer container; the drawer is slidably mounted in the drawer container; the magnetic field assembly is configured to provide a magnetic field to a stored item in the drawer; the air inlet duct assembly is configured to enable cold air to first cool the magnetic field assembly, and then enter the drawer container in a manner of not directly blowing the stored item; the air return opening is formed on the drawer container for discharging the air in the drawer container.
