Efficient microwave oven waveguide box structure

Abstract

The invention relates to the technical field of microwave oven heating, in particular to an efficient microwave oven waveguide box structure which comprises a microwave oven box body, a straight waveguide box and a microwave generator, a microwave oven cavity is formed in the microwave oven box body, and a microwave inlet is formed in the first end of the straight waveguide box and fixedly connected with the microwave generator. The second end of the straight waveguide box is provided with a microwave outlet, the microwave outlet is communicated with the microwave oven cavity, the microwave outlet is provided with a stirring antenna, and a microwave flow channel is arranged in the straight waveguide box. The straight waveguide box is adopted to replace an L-shaped waveguide box in the prior art, so that microwaves output by the microwave generator are better transmitted to the microwave oven cavity in the microwave oven box body after passing through the straight waveguide box, energy-saving and efficient effects are higher, heating is more uniform, the anode temperature is low when the microwave generator is in an idle load, and the service life of the microwave oven is prolonged; and the straight waveguide box is adopted, the microwave transmission distance is short, the manufacturing process is simpler, the manufacturing cost is effectively reduced, and the design layout of the space in the machine is facilitated.

Description

technical field [0001] The invention relates to the technical field of microwave oven heating, in particular to a high-efficiency microwave waveguide box structure. Background technique [0002] Microwave ovens are a kind of cooking utensils in household appliances. They usually include a cooking cavity box, a waveguide and a microwave generator. The microwave generator and waveguide are arranged on the box. The microwave generator communicates with the cooking cavity through the waveguide, The microwave generated by the microwave generating device is sent into the cooking cavity, and the food in the cooking cavity is heated and cooked by utilizing the microwave. [0003] In the prior art, the waveguide box adopts an L-shaped structure (such as Figure 8 The shown L-shaped waveguide box 16) has complex manufacturing process and high cost, and the transition position of the L-shaped waveguide box 16 is a vertical structure, which makes the microwave passability in the wavegui...
