Abstract: A radiographic inspection device and a method of inspecting an object are provided. The radiographic inspection device includes a support frame, where an inspection space applicable to inspect an object is formed within the support frame, and the inspection space has a first opening connecting to an outside; a transfer mechanism applicable to carry the object and move through the inspection space; a shielding curtain mounted at the first opening; and a driving mechanism. The driving mechanism includes: a driver mounted on the support frame; and a joint portion, where an upper end of the shielding curtain is connected to the joint portion. The driver is configured to synchronously drive two ends of the joint portion, so that the shielding curtain moves up and down with the joint portion to open or close the first opening.

Abstract: A microwave oven includes a housing having a receiving chamber therein. An inner case is provided in the receiving chamber. A left air channel is formed between a left side wall of the receiving chamber and a left side of the inner case, a right air channel is formed between a right side wall of the receiving chamber and a right side of the inner case. Respective fans are provided in the left and right air channels, each of the left and right fans including a front impeller, a rear impeller and a driving motor. At least one of the front and rear impellers is adjacent to at least one of front and rear walls of the receiving chamber which is corresponding thereto, at least one of the front and rear impellers is spaced from the driving motor at a predetermined distance.

Abstract: The present invention relates to a microwave oven including an oven door and a heating chamber with a back wall, and the oven door is installed in the front of the heating chamber. There are more than one protrusion disposed on the back wall, and each of the protrusions has more than three reflecting surfaces and protrudes toward an inside of the heating chamber. The back wall of the heating chamber in the microwave oven has the structure of a plurality of reflecting surfaces, which makes the microwave emitted by a magnetron reach every position of the heating chamber by reflection of the multiple reflecting surfaces, thereby the microwave distributes more evenly and consistently, thus the food may be heated more rapidly and uniformly.
