Description
Technical field
The present invention relates to a kind of micro-wave oven.Particularly relate to a kind of structure with noiseproof cooking cavity of microwave oven rear board that can reduce the reliability of resonance raising micro-wave oven.
Background technology
Generally, micro-wave oven is that (per second is about 2,450MHz) is heating source, the intermolecular frictional heat that is taken place by the molecules align that confuses food and arrange the utensil of food with high frequency waves.
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of hot air convection type ripple stove, and Fig. 2 is the planar structure schematic diagram of the internal structure of Fig. 1.
As shown in Figure 1, hot air convection type ripple stove comprises: by front panel 11 and rear board 13 and the cooking cavity assembly 10 that constitutes; Cooking cavity 12 in the 10 inner sides formation of cooking cavity assembly; Be formed on cooking cavity assembly 10 inner opposite sides, be provided with the electric control chamber 14 of various electric components; Be arranged on the shell 20 in the outside of cooking cavity assembly 10.
The a plurality of fresh air inlet 13a of formation that are communicated with cooking cavity 12 inner spaces to the central part greatly of plate 13 in the back, in the back the back of plate 13 be provided with and rear board 13 between have the convection cell 40 in any space.
In the space that convection cell 40 is had, be provided with barbecue tube 41, and the convection fan 42 that makes the hot gas convection current in cooking cavity 12 that takes place from barbecue tube 41 is installed, and being equipped with in the back of convection cell 40 in order to drive convection fan 42, and the motor 43 that is connected with the axle of convection fan 42.
Be installed with the convection cell cover 50 of parcel convection cell 40 and motor 43 in the back on the plate 13, convection cell 40 and motor 43 are protected from the outside.
The back of convection cell cover 50 is formed with a plurality of air suction inlet 50a that can flow into air from the outside.
Comprise the magnetron 14a that generates microwave by installation on the electric control chamber 14, supply with high-tension high-tension transformer 14b to magnetron 14a, and the fan electromotor 14d of the blowing fan 14c of the various electric components of cooling electric control chamber 14 inside and driving blowing fan 14c.
Fan electromotor 14d is fixedly mounted on the inner face of rear board 13 1 sides, and around blowing fan 14c wind deflector is installed, thereby the guiding air is mobile.
But, just be formed with fresh air inlet 13a in the central on the rear board 13 of existing hot air convection type ripple stove, on the neighboring of fresh air inlet 13a, be formed with exhaust vent 13b, and barbecue apparatus is arranged on the rear side of rear board 13, and is fixed on the rear board 13.When roasting, the motor 43, fan 42 and the barbecue tube 41 that constitute barbecue apparatus are started working, high speed hot blast fan 42 drives whole body of heater and slightly shakes, along with the lengthening of barbecue time, the vibrations aggravation produces noise, and, rear board also will produce distortion, and its distortion will have influence on the thermal effect that adds of micro-wave oven, has reduced the performance of micro-wave oven.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of and can reduce the structure with noiseproof cooking cavity of microwave oven rear board that resonance improves the reliability of micro-wave oven.
The technical solution adopted in the present invention is: a kind of structure with noiseproof cooking cavity of microwave oven rear board, middle part at the rear board of hot air convection type ripple stove cooking cavity is formed with the fresh air inlet that is connected with convection cell, the periphery of fresh air inlet is formed with exhaust vent, between exhaust vent and the figure formed by fresh air inlet, be formed with a circle groove, be formed with convex rib structure in the inboard of the figure of forming by fresh air inlet.The described figure of being made up of fresh air inlet is a kind of in rectangle or the circle.
A described circle groove that between exhaust vent and the figure formed by fresh air inlet, forms be shaped as a kind of in rectangle or the circle.
The described convex tendon that forms in the inboard of the shape of forming by fresh air inlet be shaped as I-shape construction.Also can be formed with fresh air inlet on the surface of described convex tendon.
Structure with noiseproof cooking cavity of microwave oven rear board of the present invention, owing between fresh air inlet on the rear board of the cooking and exhaust vent, formed groove, the place is formed with convex tendon at air inlet, strengthened the fastness of rear board, and changed the resonant frequency of the barbecue apparatus of rear board and its rear side, so when roasting, rear board can not produce resonance with barbecue apparatus, so big vibrations can not occur, can not produce noise yet, improve the performance of micro-wave oven, guaranteed the thermal effect that adds of micro-wave oven.

The specific embodiment
Below, describe the structure with noiseproof cooking cavity of microwave oven rear board of the present invention in detail with specific embodiment in conjunction with the accompanying drawings.
Fig. 4 is the partial structurtes schematic diagram of cooking cavity rear board of the present invention.
As Fig. 4, shown in Figure 5, structure with noiseproof cooking cavity of microwave oven rear board of the present invention, middle part at the rear board 23 of hot air convection type ripple stove cooking cavity 12 is formed with the fresh air inlet 23a that is connected with convection cell 40, and all fresh air inlet 23a have formed a rectangle frame pattern or circular block diagram case jointly.The periphery of fresh air inlet 23a is formed with exhaust vent 23b, is formed with a circle groove 24 between exhaust vent 23b and the figure be made up of fresh air inlet 23a, its groove 24 be shaped as rectangular recess frame or circular groove frame.Be formed with convex rib structure 25 in the inboard of the figure of being made up of fresh air inlet 23a, described convex rib structure 25 is an I-shape construction.On the surface of convex rib structure 25, can also be formed with fresh air inlet.
Structure with noiseproof cooking cavity of microwave oven rear board of the present invention, increased groove at rear panel of microwave oven with the position that the hot-air system of barbecue apparatus cooperates, increased the convex tendon of " worker " font at the air inlet position of rear panel of microwave oven, at first guaranteed the intensity of rear panel of microwave oven, when micro-wave oven is roasted, when body of heater slightly shakes with the hot blast fan, avoid the rear panel of microwave oven distortion, or even the distortion of body of heater, big vibrations even noise can not appear, and the direction of the convex tendon of " worker " font is toward body of heater inside, suitable increasing the flowing space of hot blast, guarantee to pass in and out the wind passage smoothly, make the microwave oven dealing better effects if.
