The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Like Fig. 1, shown in Figure 2, the simple and easy hot air convection micro-wave oven shown in the present embodiment comprises:
Body of heater 9 is formed for the furnace chamber of food container in it;
One cover heat-generating pipe 5 is arranged on the said body of heater, is used for heat food on the one hand, on the other hand the air of collecting is heated;
Magnetron 1 is arranged on said body of heater 9 right sides;
Reflector 7;
Controller (not marking among the figure), said controller is electrically connected with heat-generating pipe, magnetron, is used for the control of whole heating process, comprises the control of temperature, time etc.;
Reflector 7 forms the heating chamber with heat-generating pipe 5; The heating chamber communicates with furnace chamber; Its heat gets into furnace chamber food is heated, and chamber one side of wherein generating heat is connected with the force air gatherer, and the force air gatherer is the tubular structure of both ends open; The one of which end communicates with the heating chamber, and the other end is collected the wind that fan produces facing to the magnetron radiator.
The force air gatherer is connected between magnetron radiator and the heating chamber, forms the closed air flow circuits, and the heating chamber communicates with furnace chamber fully.It is indoor to import heating behind the air-flow process magnetron radiator of force air gatherer with fan 8 generations again; Be heated the condition of high temperature; Hot-air enters into the furnace chamber the inside then, thereby the hot-air in the furnace chamber is flowed evenly, makes that the heating of micro-wave oven is more even sooner.
The force air gatherer is any air trapping that can fan be come out and the device that imports to the heating chamber; Force air gatherer shown in the present embodiment comprises guide duct 4 and wind collecting unit 3; Guide duct 4 one ends communicate with the heating chamber; The guide duct other end is connected with wind collecting unit 3, and wind collecting unit 3 is facing to magnetron radiator 1.Get into guide duct behind the air trapping that wind collecting unit comes out the magnetron radiator, guide duct imports to the convection current that air is heated and realized in the heating chamber with air.
In the present embodiment; For make the collection efficiency of air the highest, the making full use of of energy, the structure optimization of said wind collecting unit is: wind collecting unit one end is that connector 301, one ends are air intake vent 302; Its connector is connected with guide duct; Connector shape and guide duct coupling, air intake vent is facing to the magnetron radiator, and air intake vent shape and magnetron radiator mate.
In order further to improve the security that micro-wave oven uses, temperature controller 6 is set on guide duct, temperature controller is connected with the heat-generating pipe circuit.Cause temperature too high if run into accidental cause, the temperature controller that is installed on the guide duct 4 just breaks off heat-generating pipe by force, and power supply quits work, and prevents danger.
