Provided are a heating device and a refrigerator. The heating device includes: a cylinder body, in which a heating cavity is defined and configured to place an object to be processed, provided with a pick-and-place opening located on a front side of the cylinder body; a door body, configured to open and close the pick-and-place opening of the cylinder body; an electromagnetic heating device, configured to generate electromagnetic waves into the heating cavity to heat the object to be processed; and magnetic elements, disposed on the door body or the cylinder body and configured to enable the door body and the cylinder body to attract each other, so that when the door body is in a closed state in which the door body seals the pick-and-place opening, the door body and the cylinder body are in close electrical contact, thereby forming a continuously conductive shielding body. By disposing the magnetic elements, on the one hand, the size of a gap between the door body and the cylinder body is reduced, and the amount of electromagnetic leakage is reduced; and on the other hand, it facilitates the door body and the cylinder body forming a continuously conductive shielding body to prevent electromagnetic waves from being emitted through the gap that may exist between the door body and the cylinder body, thereby effectively shielding the electromagnetic radiation and eliminating the harm of the electromagnetic radiation to the human body.

Aspects include a system that allows a microwave oven to intelligently self-choose the optimal cooking time for various items to prevent over/under cooking as well as overcoming cooking inconsistencies that are inherent in non-intelligent microwave ovens. Cooking time optimizations can be performed by controlling radio-frequency emission, cooking time, and/or rotation or movement of a turntable or platter within a microwave cavity of a microwave oven to more evenly heat the contents therein.

A non-pizzeria vending outlet includes a freezer, a microwave oven, and a cooktop, where the vending outlet has no means for preparing pizza dough or for baking pizza and where the vending outlet overcomes obstacles that deter non-pizzeria restaurants from vending pizza.

In accordance with aspects of the present disclosure, an autonomous robot vehicle is disclosed. In various embodiments, the autonomous robot vehicle includes a conveyance system, a securable compartment configured to autonomously lock and unlock where the securable compartment contains an item for delivery to a particular individual, a personal identification reader, at least one processor, and a memory storing instructions. The instructions, when executed by the processor(s), cause the autonomous robot vehicle to, autonomously, travel to a destination location of the particular individual, capture by the personal identification reader at the destination location a personal identification object, determine that the captured personal identification object matches an identity of the particular individual, and unlock the securable compartment based on the determination.
