The wind that machine 700 is blown out flows directly to exhaust air flue 420 without smoke duct 410 under the barrier effect of exhaust cap 800
In, and then as the flue gas being discharged by outlet flue is expelled to outside oven together.
The setting of exhaust cap 800 effectively blocks cold wind that cooling fan 700 is discharged into smoke duct 410
Flow backward, reduce the smoke flow resistance in smoke duct 410, enables the flue gas swimmingly row of flowing under the action of negative pressure
At mouth 650.Moreover, such setting, temperature in cavity 100 is also reduced caused by flowing backward due to cold wind to cavity 100
The unstable situation in field, to improve the efficiency of the present embodiment oven to a certain extent.
Please continue to refer to Fig. 1 to Fig. 3, in the present embodiment, exhaust cap 800 covers the top for being located at exhaust tube 500, also, edge
Flow direction of the air-flow in smoke duct 410, exhaust cap 800 extend to protrude from the bus of exhaust tube 500.It is such to set
It sets, so that can be blocked completely above exhaust tube 500, to effectively prevent in exhaust air flue 420 air-flow to cavity 100
Interior reverse irrigation further improves the efficiency of the present embodiment oven.
Please continue to refer to Fig. 1 to Fig. 3, in the present embodiment, along flow direction of the air-flow in smoke duct 410, Smoke
The flow area in road 410 is gradually reduced.Such setting, so that flowing velocity of the flue gas in smoke duct 410 is promoted.
Please continue to refer to Fig. 2, Fig. 5 and Fig. 6, in the present embodiment, exhaust cap 800 is detachably connected on leeward guidance tape 620.
Such setting, convenient for removing exhaust cap 800 to carry out maintenance to purifying part 900 and replacement is handled, to ensure that pair
The reliability of gas cleaning in cavity 100.
Specifically, in the present embodiment, closing one end of exhaust cap 800 is provided with flanging please continue to refer to Fig. 2 and Fig. 5, with
It is plugged on exhaust cap 800 in leeward guidance tape 620 by flanging, the other end of exhaust cap 800 is provided with fixation hole, so that even
Fitting can pass through fixation hole and exhaust cap 800 is locked in leeward guidance tape 620.
Please continue to refer to Fig. 1 to Fig. 3, in the present embodiment, windward guidance tape 630 may include tilting section, specifically, tilting section
Extend inclination to the direction close to door body 300 from top to bottom.Such setting, when so that air-flow being flowed at tilting section, because logical
Flow area reduces and increases the flowing velocity of air-flow, to improve radiating efficiency.
Please continue to refer to Fig. 1, Fig. 2 and Fig. 3 and Fig. 5 and Fig. 6, in the present embodiment, which can also include by cavity
The shell 200 of 100 packages and the air channel base plate 610 for being installed on shell 200, specifically, windward guidance tape 630, leeward guidance tape
620 are successively spaced setting with air channel base plate 610, and windward guidance tape 630 and leeward guidance tape 620 are also installed on shell.Wherein, under
Wind inlet channel 430, the air inlet 310 of wind inlet channel 430 and cooling fan 700 are formed between air duct board 620 and air channel base plate 610
It is connected.
In addition, in the present embodiment, door body air duct 440, door body air duct are additionally provided in door body 300 please continue to refer to Fig. 1
440 lower section is provided with coupled air inlet 310, and the top in door body air duct 440 is connected with wind inlet channel 430.
When oven is started to work, cooling fan 700 starts, in the course of work of cooling fan 700, wind inlet channel
430 inside form negative pressure so that the air inlet 310 of extraneous cold wind from 300 lower section of door body be inhaled into door body air duct 440 with
It radiates to door body 300；Then, the cold wind in door body air duct 440 continues to run in wind inlet channel 430, and from blower into
Air port 310 enters blower, and is expelled in exhaust air flue 420 from fan outlet 640, then by the air outlet of oven front
640 discharges are taken out of to radiate and conduct the heat generated for door body 300 and cavity 100.Meanwhile the flue gas warp in cavity 100
Exhaust tube 500 flows into exhaust air flue 420 from smoke outlet 650, as the air-flow in exhaust air flue 420 is together by air outlet
640 discharges.
