Abstract
The invention discloses a microwave oven wind scooper. A wind scooper body is formed by multiple bending and stamping a metal board; the left side and the right side in the wind scooper are open; the end part of the upper surface of the wind scooper body bends upwards; the end part of the lower surface of the wind scooper body bends upwards; and a projection extending outwards is formed on the upper surface of the right side of the wind scooper. The invention has the beneficial effects that the projection formed on the upper surface of the wind scooper can be inserted into the upper housing of a magnetron so as to clamp the magnetron; then a bolt fixes the magnetron in good condition; the lower surface of the wind scooper is bent to limit the installation position of the magnetron; the high bending part of the 1/3 of the upper surface is in contact with the upper edge of a furnace body, thus avoiding the phenomenon that the wind scooper swings because wind blows, and lowering noise. The invention has simple structure, convenience and practicality and effectively improves the overall performance of the microwave oven.
Description
Technical field
The present invention relates to a kind of microwave oven component, particularly relate to the wind scooper in a kind of micro-wave oven.
Background technology
In general micro-wave oven is to be heating source with high-frequency microwave per second 2450MHz, makes intermolecular vibration, the equipment that utilizes the frictional heat between food molecule to cook.
As shown in Figure 1, the shape of micro-wave oven 100 is cuboids, constitutes end face and two sides by shell 200, and chassis 220 combines with rear board 240, constitutes the overall appearance of micro-wave oven 100 together.Be formed with the culinary art chamber 300 of cooking food in the inside of shell 200.
The front panel of above-mentioned culinary art chamber 300 has an opening, and the end of open front face in culinary art chamber 300 be an axle, and the fire door 320 that can rotate to a side is installed, and rotating fire door 320 can open or close the front panel of cooking chamber 300.
At the other end of culinary art chamber 300 front panels, the operation panel 400 that oriented outside is outstanding.Display screen, operation knob and operation knob etc. are installed on the operation panel 400.Operation panel 400 constitutes the front appearance of micro-wave oven with fire door 320.
The back of operation panel 400, the right-hand end of promptly cooking chamber 300 are electric control chambers 500 that control circuit is installed, and electric control chamber 500 comprises magnetron 520, high-tension transformer 540 and the high-voltage capacitor 560 etc. that make micro-wave oven 100 work.
As depicted in figs. 1 and 2; Usually the magnetron 520 in the micro-wave oven is fixed on the wind scooper 530; Be formed with an outside protrusion 531 at the lower side portion of wind scooper and wind scooper; Said protrusion 531 vertically bends after the upwards vertical bending in the bottom of wind scooper 530 more laterally; Said protrusion inserts the space of magnetron 520 bottoms, and the top of magnetron is fixedly connected through screw with the through hole of the top edge of wind scooper, and the bending part 532 of said wind scooper upper surface contacts with cavity of microwave oven.But the shortcoming of above-mentioned existing common microwave stove wind scooper is: the protrusion 531 of wind scooper often can not insert in the space of the bottom of magnetron reserving when wind scooper combined with magnetron; But magnetron is installed on the protrusion; Even insert in the space of reserving the magnetron bottom; Because the weight of magnetron self only depends on the fixing magnetron outward inclining that still makes easily of screw; Described bending part 532 fan when micro-wave oven is worked is also worked thereupon, can slide up and down along body of heater as the out-of-date wind scooper of wind, also can produce noise; Accident potential appears in the termination contact of wind scooper and wire harness easily in addition, influences the reliability of micro-wave oven.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of existing common microwave stove wind scooper, provide a kind of simple in structure, easy for installation, save the activity duration, the microwave oven wind scooper of enhancing productivity.
The technical scheme that the present invention adopted is: a kind of microwave oven wind scooper, the wind scooper body by a metallic plate repeatedly bending be stamped to form, the left and right sides of wind scooper inner space is opened wide; The bending that makes progress of the upper surface end of wind scooper body, the lower surface end of the wind scooper body bending that makes progress, said wind scooper right side upper surface is formed with protrusion laterally.
The height of the bending of whole bending 1/3 part in left side, said upper surface end can contact with the top of body of heater, and said upper surface bending part contacts with the body of heater face, and 2/3 part of said upper surface bending upwards is bent with 3mm～5mm.
Said protrusion bends downwards along wind scooper upper surface right side edge, and the height of bending is the thickness of magnetron upper shell, and outwards vertical again bending back is parallel with upper surface.
The lower surface end of the said wind scooper body bending 3mm～5mm that makes progress.
The invention has the beneficial effects as follows: the protrusion that forms at the wind scooper upper surface can insert in the upper shell of magnetron, thereby clamps magnetron, and fixing intact through the firm magnetron that makes of screw again, the bending of wind scooper lower surface can limit the installation site of magnetron; The high bending of upper surface 1/3 part can prevent that rocking from appearring in the out-of-date wind scooper of wind, thereby also reduce noise owing to contact with the top edge of body of heater in addition.The present invention is simple in structure, convenient and practical effective overall performance that improves micro-wave oven.

The specific embodiment
As shown in Figure 3, microwave oven wind scooper of the present invention, wind scooper 10 bodies by a metallic plate repeatedly bending be stamped to form, the left and right sides of wind scooper inner space is opened wide; The upper surface end 11 upwards bendings of wind scooper body, the lower surface end 12 upwards bendings of wind scooper body, said wind scooper 10 right side upper surfaces are formed with protrusion 13 laterally.The height of the bending of whole bending 1/3 part in left side, said upper surface end can contact with the top of body of heater, and said upper surface bending part contacts with the body of heater face, and 2/3 part of said upper surface bending upwards is bent with 3mm～5mm.Said protrusion 13 bends downwards along wind scooper upper surface right side edge, and the height of bending is the thickness of magnetron upper shell, and outwards vertical again bending back is parallel with upper surface.The lower surface end 12 of said wind scooper 10 bodies is bending 3mm～5mm upwards.
Below; The process that microwave oven wind scooper of the present invention is combined with magnetron briefly explains: the protrusion on the wind scooper inserts the space in the magnetron upper shell; The thickness that produces during bending for the first time is identical with the thickness of magnetron upper shell; The upper surface of wind scooper and the upper surface of magnetron form level when magnetron cooperates installation with wind scooper after; When the inner space of wind scooper is inserted in the bottom of magnetron, blocked, prevent excessively going deep into of magnetron by the bending of the bending of wind scooper lower surface and side surface.This apparatus structure is simple, and is easy for installation, improved the overall performance of whole micro-wave oven.
