    • 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. Circuitry is provided for monitoring progress of the preparation and delivery cycle and for refunding purchase price in the event the machine is empty or a malfunction occurs. Additionally, the machine may be adapted for monitoring and recording machine status and for notifying a remote location telephonically of problems or maintenance needs.
    • 无人看管的机器有一个料斗,用于储存均匀尺寸,个别,冷冻或冷藏食品的库存,并将库存保持在冷冻或冷藏状态。 通过电光机构验证插入到真正的美元钞票的机器,该电光机构通过使料斗下方的微波炉打开并旋转到位于分配器下方的食物接收位置的信号控制和监视电路来启动食物准备 在料斗下面,然后通过重力将单个部分食物分配到烘箱中。 烤箱然后旋转到水平烹饪位置并关闭其门,其中该部分由微波能量加热预定的时间长度。 加热完成后,烤箱门打开,烤箱向下倾斜,食物的加热部分通过重力通过机器中的开口或端口分配。 提供电路监控准备和交付周期的进度,并在机器为空或发生故障时退还购买价格。 此外,该机器可以适用于监控和记录机器状态,并且用于通过电话通知远程位置的问题或维护需求。
