In this embodiment, the vending machine microwave with camera 11 heating can be located under all the trays (figure 2)and between the average height of the chassis (figure 3). In the latter case can be heated only those products that are placed on trays above the microwave, and the products are placed on the trays below the microwave oven, can be issued only in a cooled state.

Vending machine according to a variant implementation, depicted in figure 1, works as follows.

Products is located on the tray 3 between the turns of the screw 4 and after selection by the purchaser of the product and its payment is included corresponding to the geared motor 5, and the screw 4 is rotated one revolution. When all are in the same range of products are shifted one position, and the end product under de is the effect of gravity falls from tray 3 down. The door 12 is in the open position "B", and the product falls on it. Control splashes on the door by using the infrared sensor 9.

If the buyer selected a product that does not require warm-up, after you hit it on the door and receiving a corresponding signal from the infrared sensor 9 displays the message on the display about the readiness of the product and removed the lock from the door 8 of the buyer. The buyer opened the door 8, takes the product directly from the door 12. After closing for the buyer doors 8 it is blocked and the machine is ready for the next cycle.

If the buyer selected product requiring heat, then after getting the product to the door and receiving a corresponding signal from the infrared sensor 9, the door 12 is rotated from position "B" to position "A". During rotation of the door 12 in position "a" product, moving together with the door, moves to the center because of the presence of the guide element with a concave surface (plate 15), falling directly under the antenna of the magnetron. After closing the door 12, the control system includes a magnetron at the time specified by the operator for this product. At the end of this time the magnetron is turned off, and the door 12 is rotated to position "B". When this message is displayed on the display of the readiness cont the KTA, and removed the lock from the door 8 of the buyer, who opened the door 8, takes the heated product directly from the door 12. After closing for the buyer doors 8 it is blocked and the machine is ready for the next cycle.

In the second embodiment, shown in figure 2, the operation of the machine is similar, with the only difference that before issuing the product and removing the lock from the door of the buyer, the door 12 with heated or chilled product (depending on buyer's choice) first rotated to position "B", dropping the product into the basket 7, and then to position "A", while allowing access into the chamber 11 of the heat and eliminating the possibility of foreign object on the concave surface of the door 12. After closing for the buyer doors 8 she locked the door 12 is translated in position "B", and the machine becomes ready for the next cycle.

When performing the vending machine according to the variant shown in figure 3, his work in the issuance of heated products is carried out similarly to the operation of the machine shown in figure 2, with the only difference that after the dissolution of the heated product in the basket 7, the door 12 may be rotated to position "A", and immediately transfer to a position "B". However due to the fact that in this embodiment, the machine mo the ut to be heated only those products, located on the trays above the microwave oven, when issuing products located on the trays below the microwave oven, the system control machine does not issue a command to the rotation of the door 12 as the product is discharged by the respective screw 4 with the tray straight into the basket 7. Execution of the machine in accordance with this variant allows to simplify the control system of the machine and completely avoid selling products (such as bottles or cans with liquids, snacks in aluminum packaging, etc. from the bottom of the trays into the oven, heat up due to operator error or failure in the control system, which prevents an explosion or fire and, therefore, increases the safety of operation of the machine.
