BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vending machine with a microwave oven which takes goods out of a goods storage, introduces them into a microwave oven, and heats them.

A conventional vending machine with a microwave oven takes out refrigerated or frozen goods from a commodity storage box and introduces it into a microwave oven on the basis of money input by a customer, as shown in Japanese Patent Office No. 56-2757, for example. The product is configured to irradiate microwaves, heat them, take them out of the microwave oven, and send them to a sales outlet.

However, since the door of the microwave oven is automatically opened and closed in connection with the selling operation, the door opening and closing mechanism is complex.

For this reason, it is difficult to bring the door and the opening in the microwave oven into close contact with each other, and if there is a gap, there is an unreasonable point that the control unit of the vending machine malfunctions or discharge occurs in the gap.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides a vending machine with a microwave oven capable of minimizing radio leakage even when the gap between the door and the opening portion in the microwave oven is somewhat uneven.

MEANS TO SOLVE THE PROBLEM In order to solve the said subject, this invention removes the goods from a goods storage, introduces it into a microwave oven, and heats it. A larger opening area is provided, and a groove is formed at the peripheral edge of the door so as to face the edge of the opening in the microwave oven, and the width dimension of the edge of the opening and the opening of the opening from the opening to the bottom of the groove. The distance is set so that the wavelength of the outgoing radio wave is 1/4, and at the same time, the groove is provided with a shielding member that protrudes from one edge to the other and shields the opening of the groove. .

The width of the most wide part of the opening and the opening from the opening of the opening to the bottom of the groove are each one of a quarter of oscillation propagation wavelength, so that the opening of the opening of the door and the microwave oven The amount of radio waves leaking out of the gap is small.

In addition, by providing the shielding member of the groove, the amount of radio waves leaked further decreases when the radio waves interfere in the groove and the impedance becomes infinite.
