The invention discloses a small-sized microwave oven with a precession rotating disc. The small-sized microwave oven with the precession rotating disc adopts one to two radiation arrays to be arrangedbehind or above a heating cavity of the small-sized microwave oven with the precession rotating disc to stimulate a higher-order-mode TEn0 mode (n is an integer, and is greater than or equal to 2) asmuch as possible so as to form standing waves in the heating cavity. The small-sized microwave oven comprises the heating cavity, at least one radiation array and the rotating disc located at the bottom of the heating cavity, the at least one radiation array each comprises at least two rows of radiators along the Z axis, and the radiation arrays radiate microwave energy to the heating cavity through a floor, the rotating disc rotates along the central axis in the perpendicular direction and proceed around the central line in the perpendicular direction of the heating cavity simultaneously. Compared with multiple resonance modes under which in a traditional microwave oven, microwave sources simultaneously stimulate respective energy in the heating cavity through waveguide and coupling holes so that control is difficult, the field distribution of the working mode of the small-sized microwave oven is determined and can be controlled; in order to further improve the heating uniformity, inventors use the rotating disc which can transversely and horizontally move or can proceed around the perpendicular axis of the heating cavity; according to the small-sized microwave oven with the precession rotating disc, the heating uniformity of the small-sized microwave oven with the precession rotating disc in a three-dimensional space is improved by controlling the microwave mode in a hollowcavity of the small-sized microwave oven with the precession rotating disc; and the small-sized microwave oven can be used for heating various materials or accelerating the speed of chemical reaction.
