Abstract
The invention discloses a double-sided overall wind shielding structure in a microwave oven, and provides two optional structures, i.e. the side panel of the double-sided overall wind shielding structure is divided into a flat type and a circular arc-shaped type. The wind shielding structure surrounds the upper half of a fan shell, and is tightly connected with the same. The connecting hole of the wind shielding structure and the connecting hole on a magnetron are matched and fixed by a bolt. The wind shielding structure is made of plastic or easily cut firm material. By adopting the double-sided overall structure, the structure prevents the air volume loss and improves the cooling effect. The circular arc-shaped side panel reduces the wind resistance, speeds up the flowing speed of the wind and improves the cooling effect, so that the internal temperature of the magnetron is greatly reduced.
Description
Technical field
The invention belongs to a kind of device of micro-wave oven, be specifically related to a kind of double-sided overall wind shielding structure in microwave oven that can bilateral keep out the wind, avoid air quantity to run off, improve cooling effect.
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.
Shown in Fig. 1～3, general commerce with microwave oven structure is: comprise by the shell that forms outward appearance, furnace chamber 20, electricity storage chamber 30, also comprise the door 40 that is arranged on furnace chamber 20 fronts.Shell forms the micro-wave oven outward appearance, also plays the effect of the inner furnace chamber 20 of protection simultaneously, so shell is general with the steel plate making with certain intensity.Shell is that the center is provided with furnace chamber 20, and it comprises the rear board 17 at the bottom panel 13 below the top panel 11 of the top and two sides that cover furnace chamber 20, protection, the front panel 15 that forms furnace chamber 20 fronts and protection furnace chamber 20 back sides.Furnace chamber 20 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 20.Electricity storage chamber 30 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 20.Be provided with a plurality of electronic units such as transformer 31, magnetron 33, cfentrifugal blower 35, capacitor 37 in electricity storage chamber 30 inside.Be provided with dividing plate 39 between the transformer 31 of electricity storage chamber 30 inside and the stirring fan (not shown).Transformer 31 and stir fan, capacitor 37, dividing plate 39 be fixed on sub-panel S above, and sub-panel S is arranged on the top separated by a certain interval of bottom panel 13.A plurality of electronic units, particularly transformer 31 and magnetron 33 play a part to produce the microwave of input furnace chamber 20 inside.In the process that generates microwave, the electronic unit heating, therefore in the time of cooking food, the temperature of electricity storage chamber 30 rises.Need to suck extraneous air for the electricity storage chamber 30 of cooling off heating, so suck extraneous air by cfentrifugal blower 35.
