Below with reference to Fig. 1-Fig. 3, describe according to the stirring piece 100 for microwave oven of first aspect present invention embodiment.
Stirring piece 100 is suitable for being located at microwave oven internal, microwave oven internal also has the microwave generator (scheming not shown) for launched microwave, stirring piece 100 is driven and is rotated by motor (scheming not shown), with the microwave in microwave oven, carry out disturbance, and then microwave energy is evenly distributed in microwave oven.Particularly, according to the stirring piece 100 of the embodiment of the present invention, be suitable for being located in Flat-plate microwave oven.
As shown in Figure 1-Figure 3, according to the stirring piece 100 of the embodiment of the present invention, be provided with through hole 10, the cross-sectional configuration of through hole 10 becomes by many end to end shapes of line segment, and wherein many line segments comprise at least one curved section.Be understandable that, the cross section of through hole 10 namely through hole 10, along the orthographic projection in the direction perpendicular to through hole 10 place planes.Will also be appreciated that " many line segments comprise at least one curved section " refers in many line segments removes this curved section, and other line segments can be that straightway can be also curved section.
The computer mould of doing according to the present inventor fits experimental result and can learn, stirring piece 100 of the present invention, while rotating in microwave oven, can be better, more effectively microwave is carried out to disturbance, improve perturbation effect, improve the center field intensity of microwave oven, and then improve the effect of cooking of microwave oven.
In preferred embodiments more of the present invention, every line segment is curved section, can improve further perturbation effect thus, improves further the effect of cooking of microwave oven.
In some embodiments of the invention, between two line segments that are often connected, pass through arc transition.As shown in Figure 1-Figure 3, that is to say, between many line segments, seamlessly transit, can avoid thus forming sharp-pointed protrusion on stirring piece 100, and then can avoid stirring piece 100 when High Rotation Speed, sharp-pointed protrusion causes the problem of sparkover and sparking, and stirring piece 100 is safer in use, and performance is more reliable.
In examples more of the present invention, example as shown in Figure 1, many curved section is the end to end first to the 8th curved section (1-8), and the arc length of the first to the 8th curved section (1-8) is respectively L1 to L8, and wherein the arc length L1 to L8 of the first to the 8th curved section (1-8) meets:
L1+L2+L3+L4 ≈ λ/2, L5+L6 ≈ λ/2, L7+L8 ≈ λ/4, λ is the wavelength of the microwave that sends of microwave oven.
Be understandable that, in the prior art, the scope of the wavelength X of the microwave that microwave oven sends is between 110mm to 130mm.By the present inventor, utilizing computer to simulate, can learn with concrete experiment acquired results, many curved sections of through hole 10 are set to eight as shown in drawings, and the arc length of these eight curved sections meets above-mentioned relation, thereby can make stirring piece 100 be greatly improved for the disturbance effect of microwave in microwave oven.
Particularly, as shown in Figure 1-Figure 3, stirring piece 100 forms circle.Every curved section of the cross section of through hole 10 forms circular-arc, and every curved section all has the center of circle.Wherein, the center of circle of at least two curved sections does not overlap, and the radius of at least two curved sections is unequal.
A concrete example as shown in Figure 1, the first to the 8th curved section (1-8) joins end to end in the counterclockwise direction successively, wherein, the center of circle of the first curved section 1 and the 5th curved section 5 is concentric, and the radius of the first curved section 1 is less than the radius of the 5th curved section 5, the first curved section 1 protrudes towards the inside of through hole 10, and the 5th curved section 5 protrudes towards the outside of through hole 10, particularly, the edge of the 5th curved section 5 contiguous stirring pieces 100.The 3rd curved section 3 protrudes towards the outside of through hole 10, and the 7th curved section 7 protrudes towards the inside of through hole 10.Further, the second curved section 2, the 4th curved section 4, the 6th curved section 6 and the 8th curved section 8 all protrude towards the outside of through hole 10.Thus, after being connected by the first to the 8th curved section (1-8) head and the tail, formed shape is more level and smooth, further improves perturbation effect.
As shown in Figure 1, according to the first embodiment of the present invention, through hole 10 is that at least two and at least two through holes 10 are around the spaced apart setting in the center of circle of stirring piece 100.By two isolated through holes 10 are set, thereby can further improve the center field intensity of microwave oven.
Preferably, the edge of stirring piece 100 is provided with outward extending protruding pinna 30.Wherein this protruding pinna 30 can adjacent through-holes 10 arrange, and can improve thus the uniformity of stirring piece 100 mass distribution, thereby stirring piece 100 is more steady when rotated.
Alternatively, the part of stirring piece 100 raises up to form lug boss, or the part of stirring piece 100 is recessed to form recess 20 downwards.Example as shown in Figure 1, stirring piece 100 can be cardinal principle plate body structure, by form lug boss or recess 20 on stirring piece 100, thereby can improve to a certain extent the disturbance effect of 100 pairs of microwaves of stirring piece, what make that microwave distributes in microwave oven is more even.
As shown in Figures 2 and 3, other embodiment according to the present invention, through hole 10 is that at least three and at least three through holes 10 are around the center of circle spaced set of stirring piece 100.Can improve under the prerequisite of microwave oven center field intensity thus, further improve the uniformity of the mass distribution of stirring piece 100, stirring piece 100 is difficult for rocking when rotated.
A concrete example as shown in Figure 2 of example, through hole 10 is three, and three through holes 10 are around the center of circle spaced set of stirring piece 100.Another concrete example as shown in Figure 3 of example, through hole 10 is four, and four through holes 10 are around the center of circle spaced set of stirring piece 100.
Preferably, lug on stirring piece frontside edge can be a plurality of, and is located at equally spacedly on the edge of stirring piece 100, not only can improve thus the mass distribution of stirring piece 100, and can installing hole 31 be set on this lug, be beneficial to the installation of stirring piece 100 in microwave oven.Particularly, can be provided with mounting bracket (scheming not shown) in microwave oven, stirring piece 100 is located on this mounting bracket, and this mounting bracket is connected with the output shaft of motor, and motor can rotate by drive installation support, and then makes mounting bracket drive stirring piece 100 rotations.Wherein, on mounting bracket, can be provided with installed part, this installed part can be through the installing hole 31 on the lug of stirring piece 100, so that stirring piece 100 is carried out to Fast Installation.
The present invention is not limited to this, and the central area of stirring piece 100 also can be provided with a plurality of installing holes 31, and the shape of installing hole 31 can be arbitrarily, such as being rectangle, circle, triangle etc., can further improve thus the stability that stirring piece 100 is installed.
In addition, stirring piece 100 center can be provided with axis hole 32, the center of mounting bracket can be provided with the axle installation portion coordinating with this axis hole 32, can make thus stirring piece 100 stably be arranged on mounting bracket, rational in infrastructure, and make this stirring piece 100 around these axis hole 32 rotations, and rotation is more stable.
The invention allows for a kind of microwave oven, this microwave oven comprises the stirring piece 100 according to first aspect present invention embodiment.By this stirring piece 100 is set, can improves the effect of boiling of microwave oven, and then promote its performance.
According to other configuration examples of the microwave oven of the embodiment of the present invention, if microwave generation system, electric-control system etc. is all known for ordinary skill person, no longer describe in detail here.
