Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 has schematically shown according to the cutaway view of electric oven 100 of the present utility model.As shown in Figure 1, electric oven 100 comprises cavity assembly 1, door body assembly 2, gas passage 3 and cooling fan 4.Wherein, cavity assembly 1 has the inner chamber body 11 for accommodating food, and is arranged on the top shell 12 at the outer top of inner chamber body 11, forms the first gap 31 between inner chamber body 11 and top shell 12.Door body assembly 2 and cavity assembly 1 hinged (as seen from Figure 4).Door body assembly 2 has a lining 21, is arranged on the outer glass 22 on lining 21 front end, is arranged on the interior glass 23 on lining 21 rear end, forms the second gap 32 between outer glass 22 and interior glass 23.The second gap 32 that gas passage 3 comprises the first gap 31 and is communicated with the first gap 31.Cooling fan 4 is arranged on outside inner chamber body 11, and can driving gas gas flow in passage 4.
Thus, according to cross-ventilation principle, utilize cooling fan 4 hot-air in the second gap 32 can be pumped to outside the second gap 32 that outer glass 22 and interior glass 23 forms by the first gap 31, in figure, arrow has been indicated air-flow direction, thereby a temperature rise for body assembly 2 is reduced rapidly.Adopt in this way and lower the temperature for door body assembly 2, Air Flow is fast, good cooling effect.And the double-deck low emissivity glass door of unnecessary use reduces a temperature rise for body assembly 2, use simple glass also can reach the object that reduces glass surface temperature rise, greatly reduce thus a manufacturing cost for body assembly 2.
As shown in Figure 3, cavity assembly 1 also comprises face frame 13.Face frame 13 is substantially perpendicular to outer top surface and the top shell 12 of inner chamber body 11 and be positioned between the two.In the time that door body assembly 2 is closed, face frame 13 is relative with the door lining 21 of door body assembly 2.The first through hole 14 is set on face frame 13, its be communicated with the first gap 31 inside and outside.
Accordingly, on door lining 21, the second through hole 24 being communicated with the first through hole 14 is set.The second through hole 24 be communicated with the second gap 32 inside and outside.From then on, the first through hole 14 has been communicated with the second gap 32 with making the first gap 31 being communicated with of the second through hole 24.Thus, the air in gas passage 3 can flow under the effect of cooling fan 4.And, by realize the first through hole 14 and being communicated with of the second through hole 24 the first gap 31 and the second gap 32 be communicated with this simple in structure, in manufacturing process, be easy to realize.
As shown in Figure 1, gas passage 3 also comprises a third through-hole 25 for a bottom that is arranged on lining 21.Third through-hole 25 be communicated with the second gap 32 inside and outside.Thereby in cooling fan 4 courses of work, the hot-air in the second gap 32 is pulled away, and cool ambient air can enter gas passage 2 by third through-hole 25.Therefore, accelerate gas exchange velocity, strengthened cooling-down effect.
As shown in Figure 3, the first through hole 14 and the second through hole 24 are slot, and first through hole 14 in the hole that is rectangle and the two ends of the second through hole 24 are circular-arc.The first through hole 14 and the second through hole 24 are laterally arranged in respectively on face frame 13 and door lining 21.The first through hole 14 is multiple being evenly arranged on face frame 13.Accordingly, and/or the second through hole 24 be evenly arranged on a lining 21 for multiple.The first through hole 14 and the corresponding setting of the second through hole 24, in use, ensured that the Air Flow in gas passage is even, thereby cooling-down effect is better.And this setup is convenient to be manufactured, and is easy to processing, and is conducive to cut down finished cost.
As shown in Figure 2, electric oven 100 also comprises the circuit unit 5 being connected with cooling fan 4.This circuit unit 5 is communicated with or ends with cooling fan power supply 52 for controlling cooling fan 4.After electric oven 100 is started working, along with the temperature in inner chamber body 11 raises, the temperature in the first gap 31 and the second gap 32 is also more and more higher.When the surface temperature rise of electric oven 100 reaches preset temperature, protruding jumping formula temperature controller 51 is connected cooling fan 4 and cooling fan power supply 52, thereby cooling fan 4 is started working, driving the Air Flow in the first gap 31 and the second gap 32 is the first gap 31 and the second gap 32 exhausting heat radiations.Thereby control the surface temperature rise of electric oven 100.After cooking food completes, the temperature of the inner chamber body 11 of electric oven 100 is still very high, also needs further to limit the surface temperature rise of electric oven 100.Now, cooling fan 4 not power-off, but work on.Until the surface temperature rise of electric oven 100 reaches after goal-selling, protruding jumping formula temperature controller 51 ends the cooling fan power supply 52 of cooling fan 4, and cooling fan 4 quits work.By circuit unit 5 is set, make protruding jumping formula temperature controller 51 control the course of work of cooling fan 4, improve the utilization ratio of cooling fan 4, strengthen cooling-down effect.
As shown in Figure 1, cooling fan 4 is arranged on the outside of inner chamber body 1, and the rear portion place of a side in inner chamber body 1.For example, cooling fan 4 can be arranged in the exocoel 17 of rear casing 15 and left outside shell 16 (not shown) compositions, and is fixed on rear casing 15.Cooling fan 4 has been arranged on the end of gas passage 3, makes cooling fan 4 can take away more heat, has increased cooling-down effect.And this set makes the compact overall structure of electric oven 100.Preferably, cooling fan 4 is suction fan.
In the application, term " front " " afterwards " is taking electric oven self direction as reference.
Although the utility model is described with reference to preferred embodiment, in the situation that not departing from scope of the present utility model, can carries out various improvement and can replace parts wherein with equivalent it.The utility model is not limited to disclosed specific embodiment in literary composition, but comprises all technical schemes in the scope that falls into claim.
