Utility model content
The purpose of this utility model is exactly in order to address the above problem, and a kind of waterproof construction of the electromagnetic oven that extends electromagnetic oven service life is provided, and it can better reach three anti-objects.
To achieve these goals, the utility model adopts following technical scheme:
A kind of waterproof construction of electromagnetic oven, it comprises electromagnetic stove lower cap element (1), be installed on the electromagnetic oven master control borad of electromagnetic stove lower cap element, fan (6), drum (5), described electromagnetic oven master control borad is electrically connected with electromagnetic stove display panel (7), the strong power part (3) of described electromagnetic oven master control borad and weak current part (2) are distributed in two wiring boards and carry out subregion layout, and weak current part is connected by communication lead (4) with strong power part, and described weak current part is packaged in protection box by casting glue structure.
Further, described fan is installed on the drum lower left corner, and described strong power part is installed on the upper left corner of drum, and described weak current part is installed on the upper right corner of drum, wherein, described fan edge is provided with respectively the diversion air duct structure (8) towards strong power part and weak current part.
Further, the described diversion air duct structure structure that is in the shape of the letter V, and this V character form structure and electromagnetic stove lower cap element one-body molded.
The utlity model has following beneficial effect:
(1) simple in structure, highly versatile.
(2) conventional master control borad is divided into strong power part and weak current part; and weak current part is placed in protection box, and encapsulating protection, meanwhile; strong power part changes heat radiation better by air channel, thereby so just can reach the object in the object prolongation electromagnetic oven circuit life-span of insulation.
Brief description of the drawings
Fig. 1 is a kind of waterproof construction schematic diagram of electromagnetic oven.
Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of waterproof construction of electromagnetic oven, it comprises the electromagnetic stove lower cap element 1 being substantially square, be installed on the electromagnetic oven master control borad of electromagnetic stove lower cap element, horizontally disposed fan 6, drum 5, described electromagnetic oven master control borad is electrically connected with electromagnetic stove display panel 7, this electromagnetic stove display panel is located at the front zone position (being the below of Fig. 1) of electromagnetic stove lower cap element, the strong power part 3 of described electromagnetic oven master control borad and weak current part 2 are distributed in two wiring boards and carry out subregion layout, and weak current part is connected by communication lead 4 with strong power part, described weak current part is packaged in protection box by casting glue structure.Described strong power part comprises IGBT, rectifier bridge stack, inductance coil, ac filter electric capacity, DC filter capacitor and resonant capacitance, and fin is placed on and on the plate wiring board of strong power part, is convenient to heat radiation together with these components and parts.Described communication lead is made up of ground wire, power line and several sample line.The connected mode of aforementioned structure belongs to known prior art, and not in this to go forth.
Described communication lead is made up of many circuits, and its form that is wound in one distributes.
Described weak current part is not owing to considering heat dissipation problem, and it carries out overall encapsulating and form casting glue structure with casting glue, and encapsulating glue used can be conventional silicon gel.
Described fan is installed on the drum lower left corner (near electromagnetic stove display panel), described strong power part is installed on the upper left corner of drum, described weak current part is installed on the upper right corner of drum, wherein, described fan edge is provided with respectively the diversion air duct structure 8 towards strong power part and weak current part, the described diversion air duct structure structure that is in the shape of the letter V, and this V character form structure and electromagnetic stove lower cap element are one-body molded, at electromagnetic stove lower cap element, arc diversion air duct wall construction are set and are conducive to the wind of fan to be sent to the cooling parts of palpus.
Referring to Fig. 1, described fan right side is provided with the second training wall structure near drum 5, and it extends to the right side (in contactless state) of diversion air duct structure towards fan upper right side, be gapped between the two, is conducive to flowing of cooling air.
The operating process of this waterproof construction:
Electromagnetic oven master control borad is divided into weak current part and strong power part, be arranged in respectively on different wiring boards, here, the structure of strong and weak electricity part belongs to known technology, the wiring board of carrying strong power part and weak current part is installed in protection box respectively, and weak current part is carried out to encapsulating operation.
In this case; weak current part is overall encapsulating and being shut completely, and the heat radiation of strong power part, by fan air duct radiation, can be protected electromagnetic oven wiring board preferably; prevent that the phenomenons such as short circuit from appearring in wiring board, and then realize the life-time dilatation of electromagnetic oven wiring board.
Omit in full the description for known technology.
The foregoing is only preferred embodiment of the present utility model, protection domain of the present utility model is not limited in above-mentioned embodiment, and every technical scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvement of carrying out under the prerequisite that does not depart from principle of the present utility model, these improve and also should be considered as protection domain of the present utility model.
