The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Referring to Fig. 1-Fig. 5; This steam microwave oven; Comprise micro-wave oven body and water tank 1; The micro-wave oven body comprises cavity 4, heat-generating pipe 5, magnetron 6, waveguide 7, stirring piece 8, ceramic wafer 9, base plate 10, heating wire 12, and an end of steam generator 3 joins through water pump 2 and water tank 1, and the other end of steam generator 3 is opened on cavity 4.Be provided with heat-generating pipe 5 in the cavity 4.Magnetron 6 joins through waveguide assemblies 7 and cavity 4.

Water tank 1 is arranged on the base plate 10 of steam microwave oven through connecting plate 11, and base plate 10 is positioned at the bottom of cavity 4.Water pump 2 is arranged on the base plate 10.Water pump 2 draws water in the water box 1 and injects in the steam generator 3.Steam generator 3 generates heat water vapor through heat-generating pipe 5 and is injected in the cavity of microwave oven 4 with cooking food.

Steam microwave oven also comprises heating wire 12, and this heating wire 12 is arranged on the top of cavity 4.In the present embodiment, heating wire 12 sticks on cavity 4 tops.

Steam generator 3 comprises water inlet pipe 31, steam generator shell 32, first heat-generating pipe 33, first temperature controller 34, second heat-generating pipe 35, second temperature controller 36 and temperature sensor 37; One end and the water pump 2 of water inlet pipe 31 join; The other end of water inlet pipe 31 passes steam generator shell 32 after-openings in cavity 4; First heat-generating pipe 33 and second heat-generating pipe 35 are arranged in the steam generator shell 32, and first heat-generating pipe 33 and second heat-generating pipe 35 are separately positioned on the water inlet pipe 31, and first heat-generating pipe 33 is connected in series with first temperature controller 34; Second heat-generating pipe 35 is connected in series with second temperature controller 36, and temperature sensor 37 is connected in series with first heat-generating pipe 33 and second heat-generating pipe 35 respectively.

The temperature of temperature sensor 37 monitoring steam generators 3.

When the temperature of steam generator 3 is spent greater than 150, can at first turn-off first heat-generating pipe 33, temperature is opened first heat-generating pipe 33 after being reduced to 150 degree again.Continue to be elevated to 180 if temperature does not reduce when spending, turn-off second heat-generating pipe 35.If temperature is reduced to 180 degree and opens second heat-generating pipe 35.
