Description

A kind of electromagnetic oven with interior waterproof structure

Technical field

The utility model belongs to the electromagentic furnace technology field, particularly the technical field of the waterproof proof and electric leakage-proof safety of electromagnetic oven.

Background technology

The allegro living needs of modern has been catered in the invention of electromagnetic oven, also have the advantage of cleaning, environmental protection, few oil smoke simultaneously, so family's utilization rate rises year by year.But the design defect that this product exists does not for many years obtain enough attention and improvement always, causes equipment repair rate height, reaches 6～8% as the individual brand repair rate, even higher.The perfection of productive profit and outward appearance is pursued unilaterally by each manufacturer, and has ignored the high repair rate that defective caused wherein.For gas burner, being put out by water because of water boiling is excessive is more common thing, but ignition trigger again after putting out by water does not influence actual use.But for electromagnetic oven, owing to be electric equipment products,, let alone flowed into the heavy damage that circuit board causes short circuit to cause by boiled water even water vapour also can influence its operate as normal.

As Fig. 1 a, 1b, 1c is the internal structure schematic diagram of opening behind the electromagnetic oven panel.By base plate 60 and

side plate

61,62,63,64 surround and drain pan have an inner chamber that is used to place electric elements, be provided with heater coil, radiator fan 7 and circuit main board 4 in the chamber, heater coil, radiator fan 7 are electrically connected on circuit main board 4.Offer radiating groove on the drain

pan side plate

61,62,63,64.From Fig. 1 b, Fig. 1 c as seen, side plate slopes inwardly to base plate 60 edges from the electromagnetic oven panel edge.When the electromagnetic oven running hours, the contact portion of the bottom of a pan and furnace panel is in high temperature, thereby cause furnace interior original paper temperature to raise, thereby this moment, radiator fan 7 was arranged the hot-air of furnace interior to the outside purpose that reaches the exhaust heat radiation of body of heater via radiating groove by forced ventilation.But when furnace panel has water when dirty, current also can flow into drain pan inside through radiating groove along side plate, soak circuit main board.

The phenomenon that burns out circuit main board because of infiltration has 30% finally to cause scrapping of complete machine.Therefore, stop the infiltration phenomenon of electromagnetic oven, improving service life is the problem that urgent need will solve.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of electromagnetic oven that solves electromagnetic oven waterproof electric leakage problem is provided.

In order to reach the foregoing invention purpose, the utility model has adopted following technical scheme: a kind of electromagnetic oven with interior waterproof structure, comprise the drain pan that a panel and is enclosed by base plate and side plate with inner chamber, be provided with heater coil in the cavity, radiator fan and circuit main board, heater coil, radiator fan is electrically connected on circuit main board, at least one block of drain pan side plate offers radiating groove, it is characterized in that: described drain pan inner chamber also is provided with a leakproof baffle plate, install between the described side plate and described circuit main board that offers radiating groove, leakproof baffle plate top offers thermovent, lower seal, and connect described base plate in the bottom.

The utility model is provided with the leakproof baffle plate in drain pan inside, between drain pan radiating groove inboard and circuit main board, and the lower seal of baffle plate.When working panel had current, current flowed down along the drain pan side plate, just in case flow in the drain pan, also continued to flow to inside owing to being provided with of leakproof plate washer intercepted water, had stopped the situation generation that the circuit main board water inlet is burnt out, and had prolonged the service life of product.Neither change its work structuring, also do not changing under the situation of exterior appearance design, keeping original outward appearance U.S., because of repair rate is low, and simple in structure, safe and reliable, cheap for manufacturing cost, can bring high economic benefit.

Below in conjunction with the drawings and specific embodiments the utility model is described in detail:

The specific embodiment

Shown in 2 figure, the anti-creeping electromagnetic oven of waterproof described in the utility model comprises panel 1, face-piece 2, coil panel 3, power supply mainboard 4, fin 5, drain pan 6, the radiator fan 7 made with the heatproof glass material.Panel 1 is placed in face-piece 2 surfaces.Be depicted as the electromagnetic oven internal structure schematic diagram of throwing off panel and coil panel as Fig. 3 a.Base plate 60 and side plate are enclosed a drain pan with the inner chamber that can be used for placing electric elements, are provided with heater coil, radiator fan 7 and circuit main board 4 in the chamber, and heater coil, radiator fan 7 are electrically connected on circuit main board 4.Wherein side plate 65 of drain pan offers radiating groove.For consideration attractive in appearance, a side plate of often selecting to be positioned at the drain pan back side is offered radiating groove.

Between the inboard and circuit main board 4 of side plate 65, be provided with a leakproof baffle plate 8, shown in Fig. 3 b.The top 81 of leakproof baffle plate 8 offers many row's thermovents, and bottom 82 seals, and is tightly connected in bottom and described base plate, also can adopt the direct and integrally formed version of drain pan base plate of leakproof baffle plate.Electromagnetic oven face-piece area is greater than the area of base plate, so four blocks of side plates of drain pan slope inwardly from electromagnetic oven face-piece edge and are connected in base plate 60 edges.As shown in Figure 4, install schematic perspective view in drain pan for leakproof baffle plate 8.

As shown in Figure 5, when the electromagnetic oven operate as normal, the bottom of a pan of flat pot and the contact portion of furnace panel are in high temperature, and the furnace interior original paper also heats up thereupon, and radiator fan 7 is realized radiating and cooling via radiating groove row to the body of heater outside by forced ventilation with the hot-air of furnace interior.After careless boiled the overflowing of the water in the pot, water outbound flows along furnace panel, and along the past dirty desktop that directly flows to of drain pan side plate, water also may flow in the drain pan along side plate, but because the iris action of leakproof baffle plate, water can not flow to circuit main board and avoid circuit main board water inlet short circuit, thereby the situation that burns out circuit main board of having stopped to intake takes place.
