The lower surface of upper cover plate 2 is provided with fastener 21 and locating part 23, on fastener 21, establishesHave the unlimited draw-in groove in front side 210, flange 11 stretches into draw-in groove 210, and the upper surface of flange 11 and first projection 111 pointsNot and the upper and lower surface close contact of draw-in groove 210, locating part 23 extend in through hole 112.

That is to say, front panel 1 is inserted in the draw-in groove 210 of upper cover plate 2 by flange 11, coordinate thereby form clamping,Upper cover plate 2 and front panel 1 are linked to formation one. Wherein, because flange 11 is provided with multiple the first projections 111, theOne projection 111 is supported in draw-in groove 210, makes that the upper surface of flange 11 and the first projection 111 can be with draw-in groove 210Upper and lower surface close contact, thus the flange 11 that is provided with the first projection 111 forms interference fit with draw-in groove 210, beforePlate 1 is connected closely with upper cover plate 2, and the gap between the two can form uniform gap in the time of appropriate design.

Meanwhile, because upper cover plate 2 is provided with locating part 23, and locating part 23 is inserted in the through hole 112 on flange 11,Locating part 23 is difficult for departing from after fastening with through hole 112. For above-mentioned interference fit, locating part 23 and through hole112 cooperation is more solid and reliable.

For example as shown in Figure 2, furnace chamber body pressure increases, and a door body for micro-wave oven is while push by chamber inner high voltage, door cognition toBefore pull front panel 1. In the time that front panel 1 is subject to tensile force f n forward, only depend on interference fit flange 11 easily from cardThe interior pull-out of groove 210. But because locating part 23 can be stuck in through hole 112, can substantially ensure front panel 1 and upper coverGap between plate 2 changes little, and even gap size can remain unchanged, thereby can ensure front panel 1 and upper coverBetween plate 2, gap is even.

In addition, because flange 11 is inserted in draw-in groove 210, and locating part 23 is inserted in through hole 112, this connectionMode had both ensured that microwave oven shell 100 dismounting were easy to maintenance, had also ensured not damage in detachable maintaining process other parts,By the designed assembling mode of the method, simple in structure, easy to operate, and can not increase excessive cost.

According to the microwave oven shell 100 of the embodiment of the present invention, by the first projection 111 is set on the flange 11 at front panel 1With through hole 112, draw-in groove 210 and locating part 23 are set on upper cover plate 2, flange 11 is inserted in draw-in groove 210, limitPosition part 23 is inserted in the through hole 112 on flange 11, not only with the flange 11 of the first projection 111 can with draw-in groove 210Form interference fit, locating part 23 also can improve coordinating between front panel 1 and upper cover plate 2 with the fastening of through hole 112Reliability, ensure front panel 1 when stressed and between upper cover plate 2 gap can keep even. And microwave oven shell 100 is torn openDress, easy to maintenance, does not damage other parts in detachable maintaining process, microwave oven shell 100 is simple in structure, is processed intoThis increasing degree is little.

Particularly, as shown in Figure 3, flange 11 is formed as strip, and multiple the first projections 111 are along the length of flange 11Direction (being left and right directions in Fig. 3) arranges at interval, like this, multiple the first projections 111 can be filled in turn orExtract draw-in groove 210, assembling, dismounting difficulty reduce.
