Description

Base when micro-wave oven drops prevents distressed structure

Technical field

The invention relates to micro-wave oven, particularly be that the base of micro-wave oven when dropping prevents distressed structure.To micro-wave oven carry out drop test or because of the user do not note reasons such as micro-wave oven drops, when micro-wave oven is subjected to impacting, prevent the base distortion.

Background technology

Usually, micro-wave oven is that (per second is about 2,450MHz) as heating source, shines on the food, the frictional heat of utilizing the vibration at high speed of molecule in the food to produce with microwave.Cooking food is become the machine of prepared food.

Fig. 1 is the exploded perspective view of known micro-wave oven outward appearance.As shown in the figure, micro-wave oven comprises, front housing 11, and shell 12, outward appearance framework 13 and body of heater 10, body of heater 10 inside are provided with the furnace chamber 20 of heating clamber and the electric component chamber 30 of various electronic components are set.

Front housing 11 is provided with the fire door 14 of opening or closing furnace chamber 20 in the front of body of heater 10.Outward appearance framework 13 constitutes front, bottom surface and the back of body of heater 10, and combines protection furnace chamber 20 and electric component chamber 30 with shell 12 and front housing 11.

Electric component chamber 30 comprises: the magnetron 31 that produces microwave; For magnetron 31 provides high-tension high-tension transformer 32; The cooling fan 33 of the various electronic components of cooling body of heater 10 inside constitutes.

In the above-mentioned micro-wave oven outward appearance framework, the downside of plate 131 is provided with flange 132 in front, is provided with base 18 at the downside of flange 132.

Fig. 2 is the cross section of the A-A part among Fig. 1, wherein simply shows the front panel 131 of electric component chamber bottom of known micro-wave oven and the integrated structure of base 18.

As shown in Figure 2, the lower end of plate 131 has formed the flange 132 that crimping is processed to rear side in front, and flange 132 utilizes screw 133 and base 18 to be installed together.

Form the reinforcement forming part 181 that increases base 18 intensity on the base 18, and at the foot rest 19 of strengthening being provided with on the forming part 181 supporting micro-wave oven weight.

The micro-wave oven of having made before dispatching from the factory, the experiment of need dropping.This is the test of carrying out in order to ensure product reliability, mainly is the impulsive force that is subjected to when dropping in the corresponding product transportation, and the impulsive force that is subjected to when perhaps dropping because of carelessness because of the user is guaranteed the operation of product quality.

As shown in Figure 2, the flange 132 terminal 132a of front panel 131 and the punch line 181a of base 18 almost align, or punch line 181a is in the rear end of flange extremity 132a.The micro-wave oven of this structure is after dropping, and distortion as shown in Figure 3 take place for base 18.

As shown in Figure 3, the reinforcement forming part 181 of base 18 is subjected to the effect of micro-wave oven impulsive force in the moment of dropping, and moves to the direction of furnace chamber 20, and the foot rest 19 on base 18 back sides also moves on and then.4 foot rests 19 generally are set on micro-wave oven base 18, and, have therefore destroyed the balance between each foot rest 19 because the foot rest 19 at the electric component chamber back side is and then strengthened forming part 181 and moved up.

Mainly be because in micro-wave oven, the parts of weight maximum all are arranged on electric component chamber, the suffered impulsive force maximum of the reinforcement forming part 181 of electric component chamber bottom surface thus, also have a reason to be, the reinforcement forming part 181 of base 18 is arranged on the rear side of the flange 132a of front panel 131, therefore can't bear the impulsive force when dropping.

Therefore, micro-wave oven in the past is after carrying out drop test, because base 18 distortion, the balance between each foot rest can be destroyed.

Summary of the invention

In order to solve the problem that above-mentioned technology exists, the invention provides a kind of integrated structure that improves the flange of base and front panel, in the drop test of micro-wave oven, or, also can keep balance between each foot rest because of a variety of causes micro-wave oven rear base that drops can not deform yet.

To achieve these goals, the technical solution used in the present invention is: comprising: in the front panel lower end of furnace chamber assembly to rear side forming method orchid; The base of foot rest is set on the flange bottom surface of plate in front, a plurality of reinforcement forming parts are set on base, intensity is set on the bottom surface of flange strengthens forming part.

The intensity that forms on the above-mentioned bottom surface is strengthened the back side of the position of forming part in electric component chamber.

Above-mentioned reinforcement reinforcement forming part is set on the flange bottom surface at the electric component chamber back side from a side of base always continuously.

The invention has the beneficial effects as follows: be provided with intensity in front on the base of the flange of plate and strengthen forming part, the flange bottom surface that the weight of electric component chamber bottom surface is mainly concentrated has following effect thus.When dropping in the drop test of micro-wave oven or because of a variety of causes micro-wave oven, intensity is strengthened the impulsive force that forming part at first supports most electric component chamber and framework, reduce to act on the impulsive force of foot rest and foot rest reinforcement forming part on every side, can prevent the distortion of base thus.Moreover, because of foot rest can not deform, can keep the balance between each foot rest thus.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:

Fig. 4 is the exploded perspective view that the base of micro-wave oven of the present invention when dropping prevents distressed structure embodiment, mainly is to show base 18 and front panel 131 in the bottom surface of micro-wave oven.

As shown in the figure, a plurality of reinforcement forming parts 181 and foot rest 19 are set on base 18.Base 18 utilizes screw 133 to be installed on the flange 132 of front panel 131.

Part shown in the figure is the front panel 131 of electric component chamber bottom surface and the base 18 of combination with it.A part of corner of base 18 is outstanding, and intensity reinforcement forming part 282 is set to outstanding position, side always.

Intensity is strengthened the structure of forming part 282 at the bottom surface of base 18 fluting aftershaping, and especially the intensity of punch line is good especially.Intensity is strengthened forming part 282 and should be set to continuously on flange 132 bottom surfaces at the electric component chamber back side from a side of base 18 always.

Fig. 5 is the cross section of the B-B part of Fig. 4, shows the front panel flange 132 of electric component chamber lower front face and the sectional view of base 18 combinations.As shown in the figure, utilize screw 133, the flange 132 that is arranged on front panel 131 is fixed on the base 18, the intensity that forms flange 132 bottom surfaces is strengthened forming part 282.

Below, described intensity reinforcement forming part 282 is prevented that the mechanism of base distortion from describing.

When micro-wave oven was carried out drop test, the parts big because of weight all concentrated on electric component chamber, so the base 18 of bottom surface and foot rest 19 relative other parts bear higher impact force.

In order to support these impulsive forces, intensity is strengthened forming part 282 and is arranged on the corner of base 18, flange 132 bottom surfaces of supporting front panel 131.

Strengthen forming part 282 because of being provided with intensity, when micro-wave oven drops for this reason, intensity is strengthened the impulsive force that forming part 282 at first supports most electric component chamber and framework, and remaining impulsive force is supported jointly by the reinforcement forming part 181 around foot rest 19 and the foot rest 19, thereby disperseed impulsive force, and can prevent the distortion of base 18 thus.
