  • Patent number: 5901877
    Abstract: An automatic vending machine has a housing containing a plurality of vertical commodity storage chamber sections in a side-by-side arrangement. A thermally-insulating divider panel is fixedly disposed between each pair of adjacent chamber sections in a manner that the adjacent chamber sections are communicated with each other through an air channel therebetween. A removable thermally-insulating divider panel is placed between a selected pair of adjacent chamber sections to block the air channel, thereby forming fist and second groups of chamber sections that are not communicated with each other. The first and the second chamber section groups can individually be refrigerated and heated, respectively. A top edge of the removable divider panel is adapted to abut a part of the corresponding fixed divider panel, and both the edges, when abutting to each other, are upwardly inclined toward the front of the vending machine so as to facilitate replacement of the removable divider panel.

  • Patent number: 5688423
    Abstract: In accordance with the present invention, a vending machine has one or more programmable cook cycles for use with one or more heat sources in cooking a food package to be dispensed to the customer. In one embodiment of this invention, each cook cycle includes a start time and a duration. Each cook cycle is associated with a heat source and a product code indicating the type of food to be cooked. Initially, cook cycles are copied into a random access memory from default cook cycles hard coded in the software program code and stored in electrically erasable programmable read only memory (EEPROM) of the vending machine controller. The cook cycles in RAM can be over written by an operator for the various type of foods to be cooked. The cook cycles in RAM are used by the vending machine to automatically cook a food product selected by a customer, without any further inputs.

  • Patent number: 5598947
    Abstract: The unattended machine has a hopper for holding an inventory of uniformly-sized, individual, frozen or refrigerated portions of food and for maintaining the inventory in a frozen or refrigerated condition. Insertion into the machine of a genuine dollar bill is verified by an electro-optical mechanism which signals control and monitor circuitry to initiate food preparation by causing a microwave oven below the hopper to open and rotate into a food-receiving position below a dispenser, located below the hopper, which then dispenses an individual portion of food into the oven by gravity. The oven then rotates to a horizontal cooking position and closes its door, where the portion is heated by microwave energy for a pre-determined length of time. Upon completion of heating, the oven door is opened and the oven tilted downward and the heated portion of food is dispensed by gravity through an opening or port in the machine.

  • Patent number: 5531156
    Abstract: An automatic taco machine can automatically make both soft and hard tacos. Storage compartments for soft tortillas and hard taco shells are mounted above a V-shaped conveyor. A soft tortilla is removable from a stack of tortills by a vacuum pick-up head and is heated and is inserted between a pair of heated plates where it is compressed and heated. A pusher bar moves downwardly through slots in the heater plates to fold the tortilla and push it onto the conveyor. A hot food dispenser and a cold food dispenser dispense hot and cold food onto the tortilla as it is moved by the conveyor. A hard taco shell is removable from a stack of taco shells by a reciprocably mounted peeler which separates the bottom taco shell from the stack and supports the stack while the bottom taco shell drops to the conveyor. The conveyor moves the taco shell past the hot and cold food dispensers.

  • Patent number: 5524790
    Abstract: An apparatus for guiding food discharged from an automatic vending machine. The apparatus comprises a guide plate fixed to a front end of a lower shutter, which is adapted to be moved back and forth to discharge easily heated food, and a guide bracket provided under a heating unit, which is adapted to guide the guide plate and the food. Since the guide plate pushes food to a discharging outlet when the heated food falls down into the guide bracket so that the user can easily take out the food of the outlet. Since it is not necessary to increase an inclined angle of the guide plate, height of the discharging part can be reduced. Hence, receptive capacity of a food stacking part is relatively increased as compared with the same sized machine.

  • Patent number: 4815302
    Abstract: The refrigerated or heated air flow within the storage chamber of a vending machine is varied by an air flow control device. A baffle plate or cover plate, or combination thereof, is used to control the direction of air flow. The position of these plates in turn is controlled by spring elements. One of the spring elements is formed of shaped memory alloy so that its recoil strength changes in accordance with its surrounding temperature. Thus, the difference in recoil strength between these spring elements changes with temperature. That difference is used to position the baffle and/or cover plates to control air circulation.
