Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in Figures 1 to 5, the ducting system of the steam box microwave oven all-in-one machine in the present embodiment includes cooking cavity 1, leads The components such as aerofoil component 2, hot air apparatus 3, three-way air valve 4, tracheae 5, inlet suction port 6, exhaust joint 7 and gas-guide tube 8.
Wherein, it is provided with air inlet 12 and venthole 11 in cooking cavity 1, to guarantee to be vented more smooth, 12 He of air inlet Venthole 11 faces setting, and in the present embodiment, air inlet 12 is set on the rear wall of cooking cavity 1, and venthole 11 is set to and cooks It prepares food on the left side wall of cavity 1, also, microwave leakage in order to prevent, air inlet 12 and venthole 11 are circular hole, and diameter is 3mm~5mm.Hot air apparatus 3 is mounted on 1 outside of cooking cavity and is used to blow to air inlet 12, and the steam in cooking cavity 1 is logical It crosses venthole 11 and is discharged into air deflection assemblies 2, and gone out by 2 conduction band of air deflection assemblies to all-in-one machine.Specifically, air deflection assemblies 2 have including wind deflector 21 and cross flow fan 22, and exhaust joint 7 is set to the outside of cooking cavity 1 and covers venthole 11, is vented Connector 7 is connected by gas-guide tube 8 with the air inlet of wind deflector 21, the air inlet of the air outlet of wind deflector 21 towards cross flow fan 22 Mouthful, the air outlet of cross flow fan 22 is towards outside all-in-one machine.When cross flow fan 22 works, negative pressure is formed at venthole 11, is cooked The steam prepared food in cavity 1 finally flows into wind deflector 21 toward aggregation at venthole 11, and cross flow fan 22 provides power and leads inflow Steam in aerofoil 21 is discharged from the exhaust outlet 312 of back plate 31.
In the present embodiment, hot air apparatus 3 includes back plate 31, fan component 32, magnetron 33 and wind scooper 34, fan component 32 are set to 31 front side of back plate and are mounted in back plate 31, and fan component 32, magnetron 33 and wind scooper 34 are set to cooking cavity 1 Right side is simultaneously set gradually from back to front, and rear air inlet 311 is provided in back plate 31, and gas outlet 341 is provided on wind scooper 34 to constitute The gas outlet of hot air apparatus 3, rear air inlet 311 are connected by fan component 32 and magnetron 33 with gas outlet 341.Specifically Ground, fan component 32 include blower tray 321, fan blade blower 322 and flabellum 323, and blower tray 321 is mounted in back plate 31, Fan blade blower 322 is mounted on blower tray 321, and flabellum 323 is mounted on fan blade blower 322, and the air inlet of magnetron 33 is just To flabellum 323, the air inlet of the gas outlet face wind scooper 34 of magnetron 33.
The three-way air valve 4 of the present embodiment has air inlet 41, the first gas outlet 42 and the second gas outlet 43, hot air apparatus 3 Air outlet be connected with the air inlet 41 of three-way air valve 4 by tracheae 5, the first gas outlet 42 of three-way air valve 4 passes through air inlet Connector 6 is connected with the air inlet 12 of cooking cavity 1, is connected outside the second gas outlet 43 of three-way air valve 4 and all-in-one machine.Three The first gas outlet 42 and the second gas outlet 43 of breather valve 4 are opened and closed under the control of controller (not shown).
The working principle of the ducting system is as follows:
When microwave mode works, fan blade blower 322 and magnetron 33 are worked at the same time, external cold under the rotation of flabellum 323 Air enters magnetron air inlet by the rear air inlet 311 of back plate 31, and cold air enters magnetron 33 and carries out cooling dissipate to it Heat flows out to form hot-air from magnetron gas outlet, and then hot-air enters in wind scooper 34, then going out by wind scooper 4 Port 341 flows to the air inlet 41 of three-way air valve 4, and the first gas outlet 42 of three-way air valve 4 is opened at this time, and three-way air valve second goes out Port 43 is closed, and hot-air successively passes through the first gas outlet 42 of three-way air valve 4 and air inlet 12 enters in cooking cavity 1.Together When, cross flow fan 22 is started to work, at the hot-air and venthole 11 in cooking cavity 1 under the collective effect of negative pressure, microwave The water vapour that food generates will enter in air deflection assemblies 2 rapidly in time, finally be discharged to the outside environment.As it can be seen that the ventilation On the one hand the hot wind that system circulation is formed after being radiated using magnetron 33 applies motive force to water vapour in cooking cavity 1, promotes Steam in cooking cavity 1 is more smoothly discharged, and on the other hand slows down the condensation of water vapour, reduces cooking cavity under microwave mode Condensed water in body 1.
When steam mode works, fan blade blower 322 and magnetron 33 do not work, and steam directly passes through 2 row of air deflection assemblies Out, identical as existing steam box microwave oven all-in-one machine.The first gas outlet 42 and the second gas outlet 43 of three-way air valve 4 are turned off, can Guarantee that the steam in cooking cavity 1 all flows into air deflection assemblies 2 to be discharged.
When steam microwave combination mode works, fan blade blower 322 and magnetron 33 are worked at the same time, and the first of three-way air valve 4 Gas outlet 42 is closed, and the second gas outlet 43 is opened, and the hot-air of outflow magnetron 33 is directly over the discharge of the second gas outlet 43, no Into in cooking cavity 1, the steam in cooking cavity 1, which all flows into air deflection assemblies 2, to be discharged.
Above description is merely a prefered embodiment of the utility model, it is noted that for those of ordinary skill in the art For, under the premise of not departing from the principles of the present invention, a variety of remodeling or improvement can be carried out to the utility model, for example, Three-way air valve can be changed to two-way Non-return air valve, the air outlet of hot air apparatus passes through the air inlet of tracheae and two-way Non-return air valve It is connected, the gas outlet of two-way Non-return air valve is connected by inlet suction port with the air inlet of cooking cavity.When microwave mode or When person's steam microwave combination mode works, two-way Non-return air valve is started to work, and cold air is after magnetron converting to hot air Into in cooking cavity, the intracorporal steam of cooking cavity is promoted more to be smoothly discharged.When steam mode work, two-way Non-return air valve It closes, fan blade blower and magnetron do not work, and steam is directly discharged by air deflection assemblies, with existing steam box microwave oven all-in-one machine Identical, these are regarded as within the protection scope of the utility model.
