Embodiment Construction
[0025] The present invention will be further described below in conjunction with accompanying drawing:
[0026] like Figure 1-3A subwoofer frequency conversion microwave oven shown includes a microwave oven cavity 7, a magnetron, a frequency conversion board 4 and an air duct system located in the installation area of the core components of the microwave oven. The air duct system includes a cold air inlet 1 arranged on the rear wall of the microwave oven cavity 7, a cooling device fixed on the rear wall of the microwave oven cavity 1, and fixed on the magnetron and the frequency conversion board 4 by screws respectively. Side air inlet channel 3 and air outlet channel. The air inlet of the air inlet duct 3 is connected with the cold air inlet 1 , and the air outlet is connected with the magnetron and the frequency conversion board 4 . The air inlet of the air outlet is connected with the magnetron and the frequency conversion board 4 , and the air outlet is connected with...

The invention relates to an ultralow-noise frequency conversion microwave oven as well as an implementation method of the ultralow-noise frequency conversion microwave oven. The ultralow-noise frequency conversion microwave oven comprises a microwave oven cavity body, a magnetron, a frequency conversion plate and an air duct system, wherein the air duct system comprises a cold air inlet, a cooling device, an air intake duct and an air exhaust duct, wherein the cold air inlet is arranged in the rear wall of microwave oven cavity body; the cooling device is fixedly arranged on the rear wall of the microwave oven cavity body; the air intake duct and the air exhaust duct are respectively fixedly arranged at two sides of the magnetron and the frequency conversion plate; the air inlet of the air intake duct is connected with the cold air inlet, and the air outlet of the air intake duct is connected with the magnetron and the frequency conversion plate; the air inlet of the air exhaust duct is connected with the magnetron and the frequency conversion plate, and the air outlet of the air exhaust duct is connected with microwave oven cavity body; the air intake duct is trumpet-shaped; the surface of the air exhaust duct is circular-arc-shaped. According to the microwave oven as well as the implementation method of the microwave oven, high-power elements which can generate heat easily can be cooled down timely and effectively so as to prevent the normal operation of the microwave oven from being affected by the damage of elements due to too high temperature, and the noise of the microwave oven can be reduced.
Description
technical field [0001] The invention relates to the technical field of microwave ovens, in particular to a subwoofer frequency conversion microwave oven and a realization method thereof. Background technique [0002] Because the existing frequency conversion microwave oven has no air duct system or the design of the air duct system is unreasonable, high-power heating components such as magnetrons and frequency conversion boards will generate a large amount of heat during operation. If the heat cannot be discharged in time, the temperature of the components will exceed the temperature limit and be damaged, resulting in the failure of the microwave oven to work normally. At present, a high-speed fan is usually used inside the frequency conversion microwave oven to cool the heat-generating components. However, the fan running at high speed will resonate with the microwave oven, causing the microwave oven to be very noisy, and the noise is generally as high as 64dB (A). Conte...
