The stirring piece 100 for microwave oven of embodiment is according to a first aspect of the present invention described below with reference to Fig. 1-Fig. 3.
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 by motor (scheming not shown) and rotates, to carry out disturbance to the microwave in microwave oven, and then microwave energy is evenly distributed in microwave oven.Particularly, be suitable for being located in Flat-plate microwave oven according to the stirring piece 100 of the embodiment of the present invention.
As shown in Figure 1-Figure 3, the stirring piece 100 according to the embodiment of the present invention is provided with through hole 10, and 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 i.e. through hole 10, along the orthographic projection on the direction perpendicular to through hole 10 place plane.Will also be appreciated that " many line segments comprise at least one curved section " refers in many line segments and remove this curved section, other line segments can be straightways also can be curved section.
The computer mould done according to the present inventor fits experimental result and can learn, stirring piece 100 of the present invention, when rotating in microwave oven, better, more effectively can carry out disturbance to microwave, 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 bar line segment is curved section, can improve perturbation effect further thus, improves the effect of cooking of microwave oven further.
In some embodiments of the invention, arc transition is passed through between two line segments be often connected.As shown in Figure 1-Figure 3, that is, seamlessly transit between many line segments, can avoid thus forming sharp-pointed protrusion on stirring piece 100, and then stirring piece 100 can be avoided when High Rotation Speed, sharp-pointed protrusion causes the problem of sparkover and sparking, and namely stirring piece 100 is safer in use, and performance is more reliable.
In examples more of the present invention, such as shown in Fig. 1, many articles of curved sections are 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 microwave oven sends.
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.Computer is being utilized to simulate by the present inventor, 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, thus stirring piece 100 can be made to be greatly improved for the disturbance effect of microwave in microwave oven.
Particularly, as shown in Figure 1-Figure 3, stirring piece 100 is formed as circular.Every bar curved section of the cross section of through hole 10 is formed as arc-shaped, and namely every bar 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, 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 contiguous stirring piece 100 of the 5th curved section 5.3rd 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, the shape formed after being connected by the first to the 8th curved section (1-8) head and the tail is more level and smooth, improves perturbation effect further.
As shown in Figure 1, according to the first embodiment of the present invention, through hole 10 be at least two and at least two through holes 10 around the spaced apart setting in the center of circle of stirring piece 100.By arranging two isolated through holes 10, thus the center field intensity of microwave oven can be improved further.
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 be arranged, and can improve the uniformity of stirring piece 100 mass distribution thus, thus 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.Such as shown in Fig. 1, stirring piece 100 can be cardinal principle plate body structure, by forming lug boss or recess 20 on stirring piece 100, thus can improve the disturbance effect of stirring piece 100 pairs of microwaves to a certain extent, what microwave was distributed in microwave oven is more even.
As shown in Figures 2 and 3, according to other embodiments of the present invention, through hole 10 be at least three and at least three through holes 10 around the center of circle spaced set of stirring piece 100.Thus can under the prerequisite improving microwave oven center field intensity, improve the uniformity of the mass distribution of stirring piece 100 further, stirring piece 100 not easily rocks when rotated.
A concrete example such as shown in Fig. 2, 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 such as shown in Fig. 3, 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 multiple, and is located on the edge of stirring piece 100 equally spacedly, not only can improve the mass distribution of stirring piece 100 thus, and installing hole 31 can be set on this lug, be beneficial to the installation of stirring piece 100 in microwave oven.Specifically, 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 to rotate.Wherein, mounting bracket can be provided with installed part, this installed part can pass the installing hole 31 on the lug of stirring piece 100, to carry out Fast Installation to stirring piece 100.
The present invention is not limited to this, and the central area of stirring piece 100 also can be provided with multiple installing hole 31, and the shape of installing hole 31 can be arbitrary, such as, can be rectangle, circle, triangle etc., can improve the stability that stirring piece 100 is installed thus further.
In addition, the center of stirring piece 100 can be provided with axis hole 32, the center of mounting bracket can be provided with the axle installation portion coordinated with this axis hole 32, stirring piece 100 can be made thus to be stably arranged on mounting bracket, rational in infrastructure, and this stirring piece 100 is rotated around this axis hole 32, and rotates more stable.
The invention allows for a kind of microwave oven, this microwave oven comprises the stirring piece 100 of embodiment according to a first aspect of the present invention.By arranging this stirring piece 100, that can improve microwave oven boils effect, and then promotes its performance.
