This invention relates to temperature control of hot beverages served in mugs/cups. It is particularly well suited for ensuring that temperatures of hot drinks can be maintained in an optimum/preferred range for long periods of time. It can also be used for heating and/or temperature control of other food items such as soups and gravy, as well as fluids/suspensions/slurries in various consumer, commercial and industrial applications. The invention achieves this by utilizing one or more compact heating blocks that comprises an electrical energy storage module with electric heating, power receiving and recharging circuits that are encapsulated together to permit total immersion in a hot drink. During use, these are be added to a drink to maintain it at a high temperature in a manner similar to ice-cubes that are used with cold drinks. A separate charger is then used to charge/recharge the heating block(s) in a non-contact manner after each use.

An integrated multifunctional vacuum cooking machine includes a cooking machine body, a heat conducting container, a vacuum pump set, a heating assembly, a temperature measuring assembly, and a control system. The cooking machine body includes a base and a top cover, a chamber recessed downward is formed in a top surface of the base, and the top cover is configured to open and close the chamber. The heat conducting container is disposed in the chamber, and defines a vacuum cavity with the top cover when the top cover closes the chamber. The vacuum pump set is communicated with the vacuum cavity. The heating assembly is configured to heat the vacuum cavity. The temperature measuring assembly is configured to measure a temperature of food materials. The control system is electrically connected to the vacuum pump set, the heating assembly, and the temperature measuring assembly.

A lighting assembly, including: (a) a frame sub-assembly; and (b) an electronics sub-assembly, wherein the electronics sub-assembly includes at least one light, and at least one heating element associated with the frame sub-assembly.

An actively heated or cooled cup or mug has a body with a chamber that can receive and hold a beverage and a heating or cooling system disposed in a cavity below the chamber. The heating or cooling system has a heating or cooling element to actively heat or cool the chamber, power storage devices, and circuitry that controls the operation of the heating or cooling elements. A sensor can detect a presence of a liquid in the chamber, the circuitry configured to turn on power to the heating or cooling elements after said liquid is detected and further configured to automatically turn off power to the heating or cooling elements upon receiving a signal indicating that the liquid in the chamber has dropped below a predetermined liquid level or been depleted completely.

The disclosure provides a power supply device for warm-keeping and heating of a container, including a bottom case and a heating device. The heating device includes a battery and a heating plate. The battery is arranged in the bottom case, and the battery supplies power to the heating plate located on an upper end of the bottom case through a wire. By arranging the heating device and the bottom case and arranging the battery and the heating plate, heating and warm-keeping functions can be realized, so that heating and warm-keeping of the container that needs to be heated can be realized in any place without connection to a power supply, which brings great convenience.

The present invention discloses a self-heating hot pot with an anti-scald structure and belongs to the technical field of self-heating hot pots. The self-heating hot pot includes an outer housing, an inner container box and a heating bag; a partition plate is arranged inside the inner container box, a bulge is arranged on the top of the inner container box, and the inner container box is placed on a supporting block on the inner wall of the outer housing by the bulge; an anti-scale device including baffles is arranged on a side wall of the outer housing, the two upper and lower baffles form a circle of heat insulation groove on the side wall of the outer housing, a heat expansion assembly is arranged in the heat insulation groove and is connected with an anti-scald plate.

A roasting/serving device has a base rack and a removably attachable raised rack. The assembled base and raised racks are held within a single pan or between a lower pan and an oppositely-oriented upper pan. The pan or pans containing the assembled base and raised racks is/are placed within a wire chafing stand with rotatable handles. The handles are rotatable to clamp together rims of the upper pan and lower pan.

An infant bottle feeding system includes an infant bottle with a chamber that receives a liquid, heating or cooling elements operable to heat or cool liquid in the chamber and sensors operable to sense parameters of the liquid in the chamber. The system optionally includes an electronic base removably attached to a bottom surface of the infant bottle and operable to deliver power to electronics in the infant bottle. The system optionally includes a thermal cover that fits over the infant bottle and releasably couples to the electronic base to enclose the infant bottle, the thermal cover insulating the infant bottle and inhibiting heat loss of the liquid in the chamber. The electronic base delivers power to the heating elements and sensors in the infant bottle only when the infant bottle is on the electronic base. The infant bottle, thermal cover and electronic base define a single travel pack unit when coupled together.

Devices, systems, and apparatuses, and associated methods of preparing a liquid food item for consumption by a liquid food item preparation device are disclosed herein. In one embodiment, a device includes an inner shell having an inner surface and an outer surface, an outer shell having an inner surface and an outer surface, the inner surface of the inner shell defining a liquid holding volume and the outer surface of the inner shell and the inner surface of the outer shell defining a vacuum chamber. The outer shell and inner shell can be configured to form an orifice to the liquid holding volume at their junction. The device can be configured to prepare a liquid food item for consumption, including by powering a heating element and mixer device that can be configured to respectively heat and mix a liquid food item in the liquid holding volume.

A system is provided for heating food. The system includes a housing and a slot, where the slot extends in a direction from the top to the bottom. The system also includes heating elements adjacent the slot. A lever is provided along one of the sides of the housing. The lever is operatively connected to the heating elements and a movable platform within the slot. The system also includes an insert comprising two elements that are rotatable about a hinge from an open position to a closed position. The insert in the closed position defines a recess to hold food. A width of the insert in the closed position is based on a width of the slot. The pair of heating elements are configured to thermally couple with the two elements of the insert upon placement of the insert in the slot and actuation of the lever.
