Abstract
The utility model provides a microwave oven frequency conversion box having a flow-guiding and heat-dissipating function which comprises a frequency conversion box formed by an upper cover and a lower cover, a frequency conversion plate arranged in the frequency conversion box, and a fan arranged opposite to the frequency conversion box. The inner side of the lower cover of the frequency conversion box is provided with a flow-guiding groove, and the flow-guiding groove enables the space between the frequency conversion plate and the frequency conversion box to be enough to prevent the frequency conversion plate from contacting the frequency conversion box. When a microwave oven works, the fan blows cool wind, the cool wind is led to the space between the frequency conversion plate and the frequency conversion box through the opening of the flow-guiding groove; and under the guidance of the flow-guiding groove, the air is distributed to achieve a frequency conversion plate cooling effect. The flow guidance height is set to be about 10 mm so as to guarantee enough wind to enter the frequency conversion box. Meanwhile, the height does not enable the frequency conversion plate to be influenced by the heat emitted from a magnetron, thereby prolonging the service life of the frequency conversion plate.
Description
Technical field
The utility model relates to microwave oven apparatus field, particularly a kind of microwave oven frequency conversion box with flow-guiding radiation function.
Background technology
Microwave oven frequency conversion plate has a large amount of electronic components to form, and while conventionally working, due to the large and a large amount of electronic component work heating of input power, need to carry out good heat radiating to frequency conversion plate, the normal work of guarantee microwave oven.Frequency conversion plate on microwave current stove is carrying out when air-cooled, often by change the shape of frequency conversion plate box guide cooling airflow to, in addition between frequency conversion plate and frequency conversion plate box, contact, the heat that magnetron self sends also can be dispersed on frequency conversion plate, the water conservancy diversion measure of allocation of the amount of air is carried out in the region that shortage need to add forced air cooling to part, cooling air utilize rate variance.
Utility model content
It is high and to the good a kind of microwave oven frequency conversion box with flow-guiding radiation function of frequency conversion plate radiating effect that the technical problems to be solved in the utility model is to provide a kind of cold wind utilance.
For solving the problems of the technologies described above, a kind of microwave oven frequency conversion box with flow-guiding radiation function described in the utility model, comprises the frequency conversion box consisting of upper cover and lower cover, is located at the frequency conversion plate in frequency conversion box, be located at the fan on frequency conversion box opposite, in described frequency conversion box, be provided with the air intake passage communicating with atmosphere.
Described air intake passage is guiding gutter.
Described air intake passage is arranged on lower cover inner side, and the setting corresponding to fan of the air inlet of air intake passage.
Described air intake passage is positioned at the below of electronic component on frequency conversion plate.
The width of described air intake passage is 25～30mm, is highly 9～11mm.
In order to make frequency conversion plate and frequency conversion box fixing more firm, described lower cover inner side is provided with screw pole, and the height of screw pole is identical with the height of guiding gutter.
Described screw pole is positioned at the center of frequency conversion box lower cover.
The beneficial effects of the utility model are: the microwave oven frequency conversion box with flow-guiding radiation function described in the utility model, lower cover inner side at frequency conversion box is provided with guiding gutter, making has sufficient space between frequency conversion plate and frequency conversion box, avoid frequency conversion plate to contact with frequency conversion box, during microwave oven work, the cold wind being blown out by fan, opening by guiding gutter is incorporated into cold wind between frequency conversion plate and frequency conversion box, under the leading of guiding gutter, carry out allocation of the amount of air, its cold wind utilance is high, the good cooling results of frequency conversion plate, the height of water conservancy diversion is arranged on 10mm left and right, to guarantee enough air quantity, enter frequency conversion box, this highly can not make frequency conversion plate be subject to the impact of the magnetron evolution of heat simultaneously, and then can extend useful life of frequency conversion plate.Lower cover inner side at frequency conversion box is also provided with screw pole, and the height of screw pole is identical with the height of guiding gutter, this screw pole can make frequency conversion plate and frequency conversion box fix more firm, increase more space simultaneously air quantity is reasonably distributed, and then reduce the impact of magnetron self-heating on frequency conversion plate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model frequency conversion box and frequency conversion plate assembling schematic diagram;
Fig. 3 is the final assembly figure of Fig. 2 in microwave oven;
