A vending machine includes a refrigerated enclosure including a housing for storage of an associated pre-packaged food product. The housing has a sidewall with a sidewall opening A door is mounted to the sidewall for closing and opening the sidewall opening. A drive mechanism is operably connected to the door and adapted to mechanically mow the door between a closed position and an opened position. The drive mechanism includes at least one sensing device adapted to determine whether the door is in one of the closed position and the opened position. A door rail is mounted to the sidewall and has a guide track. The door is movably received in the guide track.

Devices and methods for RF heating of food, using techniques which allow uniformity and/or controlled non-uniformity.

A vending machine includes a main unit, and a secondary unit separate from and operably connected to the main unit. The secondary unit includes a refrigerated enclosure for housing pre-packaged food products and an oven for selectively cooking the pre-packaged food products. The main unit includes a transfer mechanism adapted to selectively remove one of the pre-packed food products from the enclosure and transfer the one pre-packaged food product to the oven for cooking. The transfer mechanism is further adapted to remove the cooked one pre-packaged food product from the oven and transfer the cooked one pre-packaged food product to a customer receiving area provided in the main unit.

A vending machine adapted for dispensing at least one pre-packaged food product includes a microwave oven. The microwave oven includes a magnetron that emits microwave electromagnetic radiation, a housing that defines a microwave cavity for receiving the food product. The housing defines a first opening to allow passage of the pre-packaged food product between outside of the microwave cavity and inside of the microwave cavity. The microwave oven also includes a first chain door that selectively covers the first opening so as to prevent the microwave electromagnetic radiation from escaping the housing through the first opening.

In vending machines that dispense food and other products, it is known to have machines that dispense stored food and other products. In this invention, selected prepackaged foods can be stored in the frozen or cold state and then prior to dispensing to the end-user, it is thawed or warmed by an internal heating process to serving temperature for customer consumption. The machine is segmentally divided both horizontally, to separate the operating machinery from food storage for hygienic and servicing reasons, and vertically, to create interchanging of the size of the modular product dispensing outlet elevator columns for adaptability to the dimensions of the stored product. Included in the design is an internal storage compartment with a mechanism that dispenses prepacked condiments that are coordinated to the selected product. This design of a vending machine may include an audiovisual screen for advertisement along with another section that identifies the available product with its calorie content. The top of the machine may have display signage that can be internally lit with color changing lights. Provisions for unattended dispensing to persons with disabilities are included by virtue of voice activated and guidance features, and illuminated and tactile surfaces.

A vending machine is adapted for dispensing a pre-packaged food product provided in a refrigerated enclosure housed in the vending machine. The vending machine includes an oven including a housing defining a cavity for receiving the pre-packaged food product. The housing has a sidewall with a sidewall opening providing access to the cavity. A side door is mounted to the sidewall for closing and opening the sidewall opening. A drive mechanism is connected to the side door and adapted to mechanically move the side door of the oven between a closed position and an opened position. The drive mechanism includes a sensing device adapted to determine whether the side door is in one of the closed position and the opened position. A door frame is mounted to the sidewall and has a guide track. The side door is movably received in the guide track.

A food vending machine has a food-preparing device and a storage device. The storage device is connected with the food-preparing device and has serving openings and a transmission mechanism. The transmission mechanism has multiple loading assemblies capable of moving along a transmission route. A food-serving method includes an ordering process, a preparing process, and a serving process. A consumer may choose later pick-up and optionally specify a pick-up time. Then, if the consumer chooses later pick-up but does not specify a pick-up time, the storage device serves the meal; if the consumer chooses later pick-up and specifies a pick-up time, the food-preparing device serves the meal, but the meal will be conveyed to the storage device after a pre-set time. Thus, a waiting time of the consumer may be reduced, and a formerly ordered but not-yet-picked-up meal may not interfere with a later consumer.
