Abstract
The utility model provides a household microwave oven which can be used for obviously improving the heating uniformity and is lower in cost, so as to overcome the defect in the prior art that the microwaves fed into a resonant cavity have strong directivity. The household microwave oven comprises a resonant cavity and a microwave generating device comprising a transmitting antenna, wherein the microwave generating device is arranged outside the resonant cavity; the transmitting antenna is inserted into the resonant cavity; a clapboard made of microwave pervious materials is arranged on the inner side of the transmitting antenna inserted into the resonant cavity; an antenna shield made of microwave pervious materials is arranged near the transmitting antenna inserted into the resonant cavity. Compared with the prior art, the household microwave oven has the effects of abandoning waveguide and traditional coupling modes, eliminating the root causes of heating uniformity, reducing the value of the electric field near the transmitting antenna, prolonging the service life of the microwave generating device, simultaneously simplifying the process, reducing the cost and saving the space.
Description
Technical field
The utility model relates to household microwave oven and has the domestic cooking device of micro-wave oven function.
Background technology
Nearest market sampling observation result shows, the heating uniformity of conventional domestic micro-wave oven can both satisfy 70% GB requirement basically, then gap was huge for the heating uniformity of no rotating disk domestic microwave cooking equipments such as the dull and stereotyped micro-wave oven of Xing Qiing, dull and stereotyped light-wave cooker in recent years, wherein under the number one brand a by the sampling observation product only reach 36%, and the improvement scheme of prior art, it is generally all not obvious to improve effect.This is because prior art, microwave source and resonator all are by the rectangular waveguide INDIRECT COUPLING, the effect of waveguide is except conduction, also be to set up the TE10 mould, but all be to be operated in the TE10 mould just because of rectangular waveguide in the practical application, the microwave that enters resonator from the feed-in window has highly directive, and it is seriously inhomogeneous to cause electric field in resonant cavity to distribute.The conventional domestic micro-wave oven is provided with rotating disk at the resonator base plate, and rotating disk not only can change load, improves the uniformity of electric field, and, can make to be in the equidistant food thermally equivalent of same level face and axis, therefore, its heating uniformity all can also reach the GB requirement basically.This no rotating disk domestic microwave cooking equipment is difficult to compare.
Summary of the invention
The microwave that the utility model is intended to overcome prior art feed-in resonator has the shortcoming of highly directive, provide a kind of and can significantly promote heating uniformity, household microwave oven that cost is lower, and be achieved by following technical proposals: a kind of household microwave oven, comprise resonator and the microwave generating apparatus that contains transmitting antenna, described microwave generating apparatus is located at outside the resonator, and its transmitting antenna inserts resonator.
Described resonator is provided with the dividing plate of being made by the material of microwave thoroughly in the inboard of the transmitting antenna that inserts; Described resonator is provided with near the transmitting antenna that inserts by the material of microwave thoroughly and makes antenna shield.
Compared with prior art, the utility model adopts transmitting antenna directly to insert the coupled modes of resonator, traditional coupled modes and necessary waveguide have been abandoned, got rid of and caused heating inhomogeneous root, reduce near the electric field value of transmitting antenna, prolonged the service life of microwave generating apparatus, simplified technology, reduce cost, saved the space.

Among the figure: 1 is resonator, 1a, 1b, 1c are not the top board of resonator, base plate and sidewall, and 2 is microwave generating apparatus, and 3 is the transmitting antenna of microwave generating apparatus, 4 is dividing plate, 5 is the Qianmen, and 5a is the liner at Qianmen, and 6 is control panel, 7 is electrothermal tube, 8 is shell, and 8b is shell bottom plate, and 9 is antenna shield.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1 and Fig. 2, these family expenses micro-wave oven comprises resonator 1, microwave generating apparatus 2 and transmitting antenna 3 thereof, Qianmen 5, shell 8, described microwave generating apparatus 2 is magnetron, be arranged on the central area of resonator base plate 1b below, its transmitting antenna 3 is inserted in the resonator 1 by the through hole that is located at resonator base plate 1b center, the top of transmitting antenna 3 is provided with the dividing plate 4 that electromagnetic wave transparent material is made, itself and resonator top board 1a, resonator sidewall 1c and preceding door lining 5a surround cooking cavity, the central area of shell bottom plate 8b is provided with recessed dish 8e, and resonator top board 1a is provided with Optical wave electric heating tube 7.These family expenses micro-wave oven has been abandoned waveguide and has been adopted traditional coupled modes of waveguide, got rid of and caused resonator internal electric field root pockety, and, because antenna inserts from resonator base plate center, even when resonance field is changed in quality for irradiation field, also can utilize the non-directional radiation characteristics of whip antenna, guarantee the uniformity of heating.
Referring to Fig. 3 and Fig. 4, these family expenses micro-wave oven is compared with first embodiment, difference is that mainly described microwave generating apparatus 2 is arranged on the top of resonator 1, part takes place and is made of electronic circuit in its microwave, its transmitting antenna and impedance matching part can separate configurations, is provided with spherical antenna shield around the transmitting antenna that inserts resonator.Therefore, can keep rotating disk; Make things convenient for impedance matching; Identical resonator container, the volume of cooking cavity is bigger.All the other do not state part, with embodiment 1.
Claims (3)
