Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings.Below with reference to
The embodiment of accompanying drawing description is exemplary, it is intended to for explaining the present invention, and be not considered as limiting the invention.
Below with reference to the accompanying drawings microwave cooking device 10 according to the present embodiment is described.As shown in Fig. 1-Fig. 9, according to this implementation
The microwave cooking device 10 of example includes shell 101, inner casing 102, smoke exhaust fan 103, cooling air channel part 104, hot blast component and electricity
Gas part 109.
Shell 101 is provided with smoke inlet 1012, exhaust opening 1013 and cold wind import 1014.Inner casing 102 is located at shell 101
It is interior, discharge flue 1021, discharge flue 1021 and smoke inlet 1012 are formed between the side plate of shell 101 and the side plate of inner casing 102
Connected with exhaust opening 1013.Smoke exhaust fan 103 is located in discharge flue 1021.Electricity piece 109 is located in shell 101.
At least a portion of cooling air channel part 104 is located in discharge flue 1021, logical with cold wind in cooling air channel part 104
Road 1041, the import 1046 of cold air duct 1041 is connected with cold wind import 1014, the outlet of cold air duct 1041 and smoke exhaust fan
103 inlet scoop 1031 is connected.The hot blast component includes hot blast motor 1051, and hot blast motor 1051 is located at being somebody's turn to do for inner casing 102
On side plate, and hot blast motor 1051 is located in cold air duct 1041.Utilize the heating article of microwave cooking device 10 (such as food)
When, hot blast motor 1051 runs and drives hot air fan 1052 to rotate, the heat in heating chamber to make microwave cooking device 10
Air circulation, so that heating is more uniform.
Smoke exhaust fan 103 is run simultaneously.Inlet scoop 1031 and the outlet phase of cold air duct 1041 due to smoke exhaust fan 103
Connect and the import 1046 of cold air duct 1041 is connected with cold wind import 1014, therefore under the suction of smoke exhaust fan 103, it is extraneous
Air entered from cold wind import 1014 in cold air duct 1041.In the mistake of extraneous air flowing in cold air duct 1041
Cheng Zhong, the hot blast motor 1051 that extraneous air is pointed in cold air duct 1041 is cooled down, and (i.e. extraneous air flows through heat

10261 and upper right smoke evacuation section 10262, right smoke exhaust fan 1034 be located at bottom right smoke evacuation section 10261 in.Right wind isolation board 1062 is provided with
The first right opening 1066 of right opening 1065 and second, the first right opening 1065 is relative with the exhaust outlet of right smoke exhaust fan 1034, the
Two right openings 1066 are relative with the inlet scoop of right smoke exhaust fan 1034.Wherein, cooling air channel part 104 is located at upper left smoke evacuation section
10252 and upper right smoke evacuation section 10262 in corresponding one in, the outlet of cold air duct 1041 and the second left opening 1064 and the
A corresponding connection in two right openings 1066.By setting left wind isolation board 1061 in left bank cigarette channel 1025 and in right row
Right wind isolation board 1062 is set in cigarette channel 1026, so as to can not only prevent the oil from the exhaust outlet discharge of left smoke exhaust fan 1033
Cigarette is drawn into left smoke exhaust fan 1033 from the inlet scoop of left smoke exhaust fan 1033 again, and is prevented from right smoke exhaust fan 1034
The oil smoke of exhaust outlet discharge be drawn into again from the inlet scoop of right smoke exhaust fan 1034 in right smoke exhaust fan 1034, and can be with
Prevent that the left smoke exhaust fan 1033 of gases affect from the exhaust outlet discharge of left smoke exhaust fan 1033 from being sucked by cooling air channel part 104
The air in the external world prevents the right smoke exhaust fan 1034 of gases affect from the exhaust outlet discharge of right smoke exhaust fan 1034 by cold
But air channel part 104 sucks the air in the external world, that is, prevents that the gas from the exhaust outlet discharge of left smoke exhaust fan 1033 from reducing left bank cigarette
The suction of the air of blower fan 1033 to external world prevents that the gas from the exhaust outlet discharge of right smoke exhaust fan 1034 from reducing right row
The suction of the air of cigarette blower fan 1034 to external world.
Advantageously, the outlet 1047 of cold air duct 1041 is adjacent to the second left opening 1064 and 1064 relative with the second left opening
Or the outlet 1047 of cold air duct 1041 is adjacent to the second right opening 1066 and 1066 relative with the second right opening.It is possible thereby to enter
One step prevents that the left smoke exhaust fan 1033 of gases affect from the exhaust outlet discharge of left smoke exhaust fan 1033 from passing through cooling air channel part 104
Suck the air in the external world or further prevent the right smoke exhaust fan of gases affect from the exhaust outlet discharge of right smoke exhaust fan 1034
1034 suck the air in the external world by cooling air channel part 104.
Advantageously, the lower end (lower end of vertical section 1044) of cooling air channel part 104 is connected with the second left opening 1064,
I.e. the outlet 1047 of cold air duct 1041 is joined directly together with the second left opening 1064, it is possible thereby to be completely eliminated from left smoke exhaust fan
The gas of 1033 exhaust outlet discharge sucks the influence of the air in the external world to left smoke exhaust fan 1033 by cooling air channel part 104.
Or, the lower end (lower end of vertical section 1044) of cooling air channel part 104 is connected with the second right opening 1066, i.e. cold wind
The outlet 1047 of passage 1041 is joined directly together with the second right opening 1066, it is possible thereby to be completely eliminated from right smoke exhaust fan 1034
The gas of exhaust outlet discharge sucks the influence of the air in the external world to right smoke exhaust fan 1034 by cooling air channel part 104.
Include as shown in fig. 6, smoke exhaust fan 103 is double-suction type vortex fan, i.e. smoke exhaust fan 103 positioned at middle part
Motor and two flabellums positioned at the left and right sides, the motor drive the flabellum to rotate, and each flabellum has the suction of left and right two
Air port and an exhaust outlet.That is, smoke exhaust fan 103 has four inlet scoops and two exhaust outlets 1032.Utilize smoke evacuation
Two air draughts of inlet scoop 1031 close to the motor on blower fan 103 cool down hot blast motor 1051, it is not necessary to hot blast motor
The extra cooling device of 1051 increases uses the high hot blast motor of the class of insulation, so as to effectively reduce being manufactured into for complete machine
This.Smoke exhaust fan 103 has larger suction simultaneously, can suck more extraneous air in cold air duct 1041, with
Just more efficiently, rapidly, significantly decrease the temperature of hot blast motor 1051, further improve the cooling of hot blast motor 1051
Effect.
