Abstract
The invention provides a scattering microwave oven and belongs to household appliances. The microwave oven comprises a magnetron, a waveguide tube and a cavity, wherein the inner surface of the cavity is wavy, and the wavelength of the cavity is 5 cm-15 cm. The scattering microwave oven is used for scattering the microwave in the cavity, thereby dispersing the concentration class of the microwave along the reflect direction, further restraining the electric charge migratory motion at the surface of the cavity, reducing the energy loss of the microwave and improving the heating efficiency.
Description
Affiliated technical field
The present invention relates to a kind of domestic electric appliance, especially, is a kind of micro-wave oven, comprises cavity, magnetron, waveguide.
Background technology
At present, micro-wave oven has become a kind of domestic electric appliance commonly used, and its inner core electric component is a magnetron; This magnetron can produce the microwave of dither, and this microwave directly acts on food after importing the food heating chamber by waveguide; Evoke its inner molecule and carry out dither, thereby heat simultaneously inside and outside making food, adopt micro-wave oven to heat; Both energy-conservation, rapid again, therefore be widely loved by the people.
However,,, when microwave runs into metallic object, will evoke big electric current, thereby both cause the loss of microwave energy, possibly cause electric discharge phenomena again in the metal surface even there is such problem for micro-wave oven, very dangerous; Yet; Cavity of microwave oven is made up of metallic plate, its role is to reflection and shield microwaves, because this metallic cavity is a ground connection; Therefore electric discharge phenomena can not take place; But still have the electric charge swarming on the cavity, this kind electric charge swarming will make microwave energy incur loss, and the efficiency of heating surface of micro-wave oven is descended.
Summary of the invention
To the problems referred to above; The object of the present invention is to provide a kind of scattering micro-wave oven; This scattering micro-wave oven can make the microwave generation scattering in the cavity, thus dispersion microwave in the direction concentration class of reflex time, thereby the electric charge that suppresses housing surface is migrated motion; Reduce the energy loss of microwave, improve its efficiency of heating surface.
The technical solution adopted for the present invention to solve the technical problems is: this micro-wave oven comprises magnetron, waveguide, cavity, and the inner surface of said cavity is wavy, and its wavelength is 5cm-15cm.
Beneficial effect of the present invention is: this scattering micro-wave oven in use; After microwave was injected said cavity in the waveguide, microwave was when the cavity internal reflection, because cavity has the waveform inner surface; And the wavelength of inner surface wavelength and microwave (about 10cm) is suitable; Therefore scattering will take place at cavity inner surface in microwave, and the directionality of its microwave reflection is comparatively disperseed, so just reduced microwave reflex time at every turn in the cavity inner surface somewhere caused electric induction intensity; Thereby reduced the energy loss of microwave, improved its efficiency of heating surface.
Description of drawings
Fig. 1 is this scattering microwave oven structure sketch map.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
In the embodiment shown in fig. 1, this micro-wave oven comprises micro-wave oven casing 1, is provided with magnetron (non-main points of the present invention, not shown), waveguide 2 in this housing 1, and housing 1 inside is cavity 3, and the inner surface 31 of said cavity 3 is wavy, and its wavelength is 5cm-15cm.
This scattering micro-wave oven in use; After microwave was injected said cavity 3 in the waveguide 2, microwave was when cavity 3 internal reflections, because cavity 3 has waveform inner surface 31; And the wavelength of inner surface 31 wavelength and microwave (about 10cm) is suitable; Therefore scattering will take place at cavity inner surface 31 in microwave, and the directionality of its microwave reflection is comparatively disperseed, so just reduced microwave reflex time at every turn in cavity inner surface 31 somewheres caused electric induction intensity; Thereby reduced the energy loss of microwave, improved its efficiency of heating surface.
