Description
Technical field
The invention belongs to a kind of device of micro-wave oven, be specifically related to a kind of fixed structure that transformer directly can be contacted, can reduce microwave oven shell vibration and noise with microwave oven shell and reduce the microwave oven transformer of transformer leakage magnetic field.
Background technology
Generally, micro-wave oven is according to generating microwave by magnetron behind the power turn-on, and arranges the device of food with heating object such as these microwave irradiation foods.Such micro-wave oven can be divided into home-use micro-wave oven that is equipped with small-sized magnetron and the commerce micro-wave oven that is equipped with large-scale or a plurality of magnetrons.Micro-wave oven can also be distinguished according to the mode of heat food, and home-use micro-wave oven generally adopts the glass plate mode of rotation food, the commercial stirring fan mode that mainly adopts dispersion microwave with micro-wave oven.Commercial be mainly used in the food supply retail shop of high convenience store of frequency of utilization or short time cooking food, generally need high relatively output compared with home-use micro-wave oven with micro-wave oven.
As shown in Figure 1, general commerce with microwave oven structure is: comprise by the shell that forms outward appearance, furnace chamber 5, electricity storage chamber 7, also comprise the door 13 that is arranged on furnace chamber 5 fronts.Shell forms the micro-wave oven outward appearance, also plays the effect of the inner furnace chamber 5 of protection simultaneously.Shell is that the center is provided with furnace chamber 5, comprises the rear board 4 by the top panel 1 of the top and two sides that cover furnace chamber 5, the bottom panel 2 below the protection, the front panel 3 that forms furnace chamber 5 fronts and protection furnace chamber 5 back sides.Furnace chamber 5 is spaces of cooking such as cooking food thing, and its shape is the quadrangular box shape of front openings, the food after promptly can putting into food and take out the cooking from opening the place ahead of furnace chamber 5.
Electricity storage chamber 7 is the spaces that are positioned at the enclosure right side, and its inside is provided with to driving a plurality of electronic units of furnace chamber 5.Be provided with a plurality of electronic units such as transformer 8, magnetron 9, cfentrifugal blower 10, capacitor 11 in electricity storage chamber 7 inside.Be provided with dividing plate 14 between the transformer 8 of electricity storage chamber 7 inside and the stirring fan (not shown).Stir fan, capacitor 11, dividing plate 14 be fixed on sub-panel above, and sub-panel is arranged on the top separated by a certain interval of bottom panel 12.A plurality of electronic units, particularly transformer 8 and magnetron 9 play a part to produce the microwave of input furnace chamber 5 inside.In the process that generates microwave, the electronic unit heating, therefore in the time of cooking food, the temperature of electricity storage chamber 7 rises.Need to suck extraneous air for the electricity storage chamber 7 of cooling off heating, so suck extraneous air by cfentrifugal blower 10.
Be provided with waveguide 6 above furnace chamber 5, waveguide 6 plays a part microwave transmission that conduction generates by the magnetron 9 of electricity storage chamber 7 to furnace chamber 5 inside.One side of waveguide 6 is provided with and drives the synchronous motor M that stirs fan.Waveguide 6 not only can be arranged on above the outside of furnace chamber 5, but also can be arranged on below the outside, and therefore if the top and bottom of furnace chamber 5 are provided with waveguide 6 separately, microwave shines the inside of furnace chamber 5 from the top to the below and from the below to the top.
As shown in Figure 2, the lower end of transformer 8 is connected with base plate 16, and at tetragonal Cheng Yousi connecting hole 17 of base plate 17, screw is fixed on transformer 8 on the bottom panel 2 by connecting hole 17.
But the transformer in the micro-wave oven of prior art is just fixed with bottom panel by four screws on the base plate, connects firmly inadequately, and the transformer leakage magnetic field causes bigger vibration and the noise of microwave oven shell generation.
Summary of the invention
The present invention provides a kind of fixed structure that transformer directly can be contacted, can reduce microwave oven shell vibration and noise with microwave oven shell and reduce the microwave oven transformer of transformer leakage magnetic field in order to overcome prior art and to have shortcoming and propose, its objective is.
Technical scheme of the present invention is: a kind of fixed structure of microwave oven transformer, and described micro-wave oven comprises top panel, and the lower end of plate is provided with bottom panel in the above, and the front end of plate is provided with front panel in the above, and the rear end of plate is provided with rear board in the above.Be provided with furnace chamber, electricity storage chamber in the space that plate, bottom panel, front panel and rear board surround in the above, front at furnace chamber is provided with door, electricity storage chamber is positioned at the interior volume right side, is provided with a plurality of electronic units such as transformer, magnetron, cfentrifugal blower, capacitor in electricity storage chamber inside.
The sidewall of transformer is provided with fixed structure, and fixed structure comprises firm banking, is formed with connecting hole in the middle of firm banking, forms a plurality of uniform support arms on the cylindrical side of firm banking.
The welding of fixed structure and sidewall also can be riveted or bonding.
It is curved that the profile of support arm is "～".
Support arm is the metallic plate with certain thickness and width.
The fixed structure of microwave oven transformer of the present invention can make the shell vibration of micro-wave oven reduce more than 70%, and the radiation noise also reduces greatly.Simultaneously, also reduce the leakage in transformer magnetic field, increased area of dissipation, be more conducive to the transformer heat radiation.
