Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a microwave cooking device. Background Art

[0002] Traditional microwave cooking equipment, such as microwave ovens and microwave ovens, are usually equipped with a microwave stirring device, which includes a stirring motor, a stirrer and other parts. The stirring motor drives the stirrer to rotate, and uses the rotational motion of the stirrer to evenly radiate the input microwaves into the cooking cavity.

[0003] Since water vapor is generated during cooking, a partition for isolating water vapor is usually provided in the cooking cavity to prevent the water vapor from entering the microwave stirring device and damaging the components. However, during the production, installation and transportation of the whole machine, the partition is often scratched or damaged by the stirrer due to vibration of the stirrer or overturning of the whole machine. Utility Model Content

[0004] In view of this, the utility model provides a microwave cooking device to solve the problem that the partition of the microwave cooking device in the prior art is easily scratched or damaged.

[0005] The utility model provides a microwave cooking device, comprising:

[0006] A shell body having a cooking cavity therein and a microwave inlet at one side of the shell body;

[0007] A stirring device is arranged at the entrance of the microwave, and the stirring device comprises a stirrer for stirring the microwave;

[0008] A partition is arranged between the cooking cavity and the stirrer to isolate water vapor and allow microwaves to pass through;

[0009] The stirring device also includes an anti-scratch member arranged on the stirrer, the anti-scratch member includes an anti-scratch portion, the anti-scratch portion protrudes from a side wall of the stirrer facing the partition, and the hardness of the anti-scratch portion is less than the hardness of the stirrer.

[0010] Beneficial effect: By arranging the anti-scratch part on the stirrer, when the microwave cooking device has an abnormality, such as the stirrer vibrates or the whole machine flips over, the anti-scratch part can first contact the partition. Since the hardness of the anti-scratch part is much smaller than the hardness of the stirrer, the partition will not be scratched. This can effectively prevent the harder stirrer from scratching the partition, causing the paint on the partition surface to peel off, affecting the performance of the product, and improving the user experience. Therefore, the problem that the partition of the microwave cooking device in the prior art is easily scratched or damaged is effectively solved.

[0011] In an optional embodiment, the agitator includes a disc-shaped agitator body, and a plurality of anti-scratch members are provided, and the plurality of anti-scratch members are arranged at intervals along the circumference of the agitator body.

[0012] Beneficial effect: By arranging multiple anti-scratch parts at intervals around the agitator, the agitator can be effectively prevented from contacting the partition during the installation or transportation of the cooking equipment. In this way, no matter which part of the agitator approaches the partition, the anti-scratch parts at that position can contact the partition first, further improving the anti-scratch effect.

[0013] In an optional embodiment, the side of the anti-scratch portion facing the partition is configured as an arc-shaped anti-scratch surface convex toward the partition.

[0014] Beneficial effect: By setting the side of the anti-scratch part facing the partition as a curved surface, the contact area between the anti-scratch part and the partition can be reduced, and the friction force is reduced. When an abnormality occurs and the anti-scratch part contacts the partition, the highest point of the curved anti-scratch surface contacts the ink surface of the partition, so that the anti-scratch part and the partition have higher freedom and smoothness, and can rotate freely and comfortably without mechanical jamming, thereby effectively preventing large-scale falling of ink on the partition and achieving better anti-scratch effect.

[0015] In an optional embodiment, the anti-scratch portion includes a D-shaped block body, the straight edge of the D-shaped block body is attached to the agitator, and the curved edge faces the partition.

[0016] Beneficial effect: The anti-scratch part adopts a D-shape, and the straight wall surface of the D-shaped anti-scratch part can fit on the outer surface of the agitator, making the fit between the anti-scratch part and the agitator more compact and stable. The curved wall surface of the D-shaped anti-scratch part serves as an anti-scratch surface to prevent the agitator from scratching the partition.

[0017] In an optional embodiment, the scratch protection element is fixed to the agitator by snap-fitting.

[0018] Beneficial effect: the anti-scratch piece is fixed on the agitator by a snap-on method, which is convenient for disassembly and assembly and is not easy to fall off.

[0021] The elastic buckle has a closed contracted state and an open clamping state. When the elastic buckle is inserted into the clamping hole, the elastic buckle is in the closed contracted state.

[0022] When the elastic buckle passes through the clamping hole, the elastic buckle is in a clamping state of being opened outwards.

[0023] Beneficial effect: The anti-scratch part adopts the design of upper elastic buckle. During assembly, the elastic buckle is constrained and squeezed by the buckle hole, shrinks inward, and is easy to install. After the elastic buckle is pressed into place and passes through the buckle hole, it can restore its deformation under the action of its own elastic force and expand outward to be fastened to the buckle hole, so that the anti-scratch part can be installed more firmly, reliably and stably. Even under high temperature conditions or in the event of overturning, collision, etc., it is not easy to fall off, and the fixing effect is better.

[0024] In an optional embodiment, the elastic buckle includes a V-shaped buckle body and a supporting rib fixedly connected between the middle of the buckle body and the anti-scratch portion.

[0025] Beneficial effects: The root of the anti-scratch piece adopts a V-shaped elastic buckle structure design with beveled chamfers on both sides. The V-shaped buckle body plays a guiding role, which facilitates the quick installation of the anti-scratch piece. The V-shaped buckle body and the middle supporting rib form a double V-shaped root design, which is firmly and stably fixed and not easy to loosen. Two gap grooves are formed between the V-shaped buckle body and the middle supporting rib. The set gap grooves facilitate the process of pressing the elastic buckle into the card hole. The V-shaped buckle body deforms inward, which is convenient for assembly. At the same time, it is also convenient for the V-shaped elastic buckle structure to be reset and fastened to the agitator after being pressed to the bottom.

[0027] Beneficial effect: The anti-scratch part is made of plastic, rubber or silicone material, which is relatively soft and will not scratch the partition, and also has a certain elasticity to play a role in buffering and shock absorption.

[0028] In an optional embodiment, the microwave inlet is arranged on the bottom plate of the housing, and the stirring device further comprises a driving mechanism installed on the outside of the bottom plate, the driving mechanism is connected to the stirrer and is suitable for driving the stirrer to rotate;

The partition is a ceramic plate or a glass plate.

[0030] Beneficial effects: By arranging the microwave inlet and the stirring device at the bottom of the shell, the partition is also correspondingly arranged at the bottom of the shell, so that the partition can not only play the role of isolating water vapor, but also play the role of supporting the food to be heated, and one thing has multiple uses. The microwave stirring chamber formed by the bottom plate being recessed downward does not occupy the space of the cooking cavity, and is convenient for the installation of the stirrer. Moreover, the partition adopts a ceramic plate or a glass plate, which can effectively isolate water vapor while allowing microwaves to penetrate, and will not affect the heating effect of food.

[0034] Beneficial effect: The first stretching platform formed by the downward depression of the reference surface is convenient for embedding the partition. Preferably, the partition is a glass plate. After the partition is embedded in the annular mounting groove, the surrounding points are sealed with silicone. The first stretching platform and the reference surface are designed with vertical stretching, so that the side wall of the annular mounting groove is a vertical wall surface, which is convenient for matching with the outer peripheral wall of the partition, reducing the movable gap of the partition, so that the partition has higher stability after being embedded in the annular mounting groove, preventing the partition from shifting and loosening after or during the glue dispensing process, resulting in uneven glue dispensing.

[0057] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0058] Since water vapor is generated during cooking, in order to prevent the water vapor generated during cooking from entering the stirring device, waveguide box and microwave generator, a partition for isolating water vapor is usually provided in the cooking cavity in the related art to prevent the water vapor from entering other components such as the stirring device and damaging the components. However, during the production, installation and transportation of the whole machine, the partition is often scratched or damaged by the stirrer due to vibration of the stirrer or overturning of the whole machine.

[0059] In addition, in order to improve the reflection effect of microwaves in the cavity and the aesthetics of the product, other silk-screen patterns such as low-temperature or medium-low-temperature inks are usually printed on the surface of the partition. When the rotating agitator jumps abnormally, the agitator can easily hit the partition and scratch the ink surface of the partition, causing the paint on the partition surface to peel off, affecting the performance of the product and giving users a bad experience.

[0060] Combine the following Figures 1 to 11 , describing an embodiment of the utility model.

[0061] According to an embodiment of the utility model, the utility model provides a microwave cooking device, which includes a shell 10, a stirring device 20 and a partition 30. The shell 10 has a cooking cavity 101 inside, and a microwave inlet 102 is provided on one side of the shell 10; the stirring device 20 is arranged at the microwave inlet 102, and the stirring device 20 includes a stirrer 21 for stirring microwaves; the partition 30 is arranged between the cooking cavity 101 and the stirrer 21, and is used to isolate water vapor, and the partition 30 allows microwaves to pass through; the stirring device 20 also includes a scratch-proof member 22 arranged on the stirrer 21, and the scratch-proof member 22 includes a scratch-proof portion 221, and the scratch-proof portion 221 protrudes from a side wall of the stirrer 21 facing the partition 30, and the hardness of the scratch-proof portion 221 is less than the hardness of the stirrer 21.

[0062] In the above embodiment, by providing the anti-scratch member 22 on the agitator 21, when an abnormality occurs in the microwave cooking device, such as when the agitator 21 vibrates or the entire machine flips over, the anti-scratch portion 221 can first contact the partition 30. Since the hardness of the anti-scratch portion 221 is much smaller than the hardness of the agitator 21, the partition 30 will not be scratched. This can effectively prevent the harder agitator 21 from scratching the partition 30, causing paint peeling on the surface of the partition 30, affecting product performance, and improving user experience. Therefore, the problem that the partition 30 of the microwave cooking device in the prior art is easily scratched or damaged is effectively solved.

[0063] Specifically, in this embodiment, the microwave inlet 102 can be arranged at the top of the housing 10 or the bottom of the housing 10, and the stirring device 20 is correspondingly arranged at the top or bottom of the housing 10. Preferably, the microwave inlet 102 is arranged at the bottom of the housing 10, and the stirring device 20 is also installed at the bottom of the housing 10.

[0064] Furthermore, since high-temperature ink cannot pass the impact and aging tests, in this embodiment, low-temperature or medium-low-temperature ink is set on the surface of the partition 30, and the ink surface is printed on the outside of the partition 30, which can reflect microwaves and improve heating efficiency. The ink surface is a silk-screen pattern, which can improve the aesthetics of the product. However, low-temperature or medium-temperature ink is easy to scratch. Therefore, in this embodiment, the anti-scratch member 22 is set on the outer circle of the stirrer 21. When the stirrer 21 jumps abnormally, the anti-scratch member 22 contacts the ink surface and will not scratch the ink.

[0065] Furthermore, in the present embodiment, the anti-scratch member 22 is a heat-resistant member made of a temperature-resistant material to prevent the anti-scratch member 22 from melting, deforming, etc. in a high-temperature environment.

[0066] In some embodiments, the agitator 21 includes a disc-shaped agitator body 211 , and a plurality of anti-scratch members 22 are arranged at intervals along the circumference of the agitator body 211 .

[0067] In the above embodiment, by arranging a plurality of anti-scratch members 22 at circumferential intervals on the agitator 21, the agitator 21 can be effectively prevented from contacting the partition 30 during the installation or transportation of the cooking equipment. In this way, no matter which circumferential part of the agitator 21 approaches the partition 30, the anti-scratch member 22 located at that position can contact the partition 30 first, thereby further improving the anti-scratch effect.

[0068] Optionally, in this embodiment, the number of the anti-scratch members 22 is four. Of course, the number of the anti-scratch members 22 may be greater than four, which is not limited in this embodiment.

[0069] In this embodiment, the stirrer 21 includes a stirrer body 211 in a disc shape, and the stirrer body 211 is provided with fan-shaped holes in the circumference. Specifically, four fan-shaped holes are provided at intervals in the circumference of the stirrer body 211 to stir the microwaves and ensure the uniformity of the microwaves. Four anti-scratch members 22 are sequentially arranged at the intervals of the four fan-shaped holes, and the four anti-scratch members 22 are arranged alternately with the four fan-shaped holes.

[0070] Preferably, in the present embodiment, a plurality of anti-scratch members 22 are arranged at intervals on the outer circle of the agitator 21. When the agitator 21 rotates abnormally, the agitator 21 may tilt. The outer circle of the tilted agitator 21 first contacts the ink surface of the partition 30. Because the anti-scratch members 22 are arranged on the outer circle of the agitator 21, when the agitator 21 tilts, the anti-scratch members 22 contact the ink surface first. Since the anti-scratch members 22 are made of softer plastic or rubber, they will not scratch the ink even if they contact the ink surface, and the anti-scratch effect is better.

[0071] In some embodiments, the anti-scratch component 22 is any one of a plastic component, a rubber component, and a silicone component.

[0072] In the above embodiment, the anti-scratch member 22 is made of plastic, rubber or silicone material, which is relatively soft and will not scratch the partition 30 , and also has a certain elasticity to play a role in buffering and shock absorption.

[0073] Preferably, the anti-scratch member 22 is made of rubber or silicone, which is softer and has better cushioning and shock-absorbing effects.

[0074] In some embodiments, the side of the anti-scratch portion 221 facing the partition 30 is configured as an arc-shaped anti-scratch surface 2211 convex toward the direction approaching the partition 30 .

[0075] In the above embodiment, by setting the side of the anti-scratch portion 221 facing the partition 30 as an arc-shaped surface, the contact area between the anti-scratch portion 221 and the partition 30 can be reduced, and the friction force is reduced. When an abnormality occurs and the anti-scratch portion 221 contacts the partition 30, the highest point of the arc-shaped anti-scratch surface contacts the ink surface of the partition 30, so that the anti-scratch member 22 and the partition 30 have higher freedom and smoothness, and can rotate freely and comfortably without mechanical jamming, thereby effectively preventing large-scale falling of ink on the partition 30 and achieving better anti-scratch effect.

[0076] In some embodiments, Figure 3 , Figure 5 , Figure 7 , Fig.10 As shown, the anti-scratch portion 221 includes a D-shaped block body, the straight edge of the D-shaped block body is attached to the agitator 21, and the arc-shaped edge faces the partition 30.

[0077] In the above embodiment, the anti-scratch portion 221 adopts a D-shape, and the straight wall surface of the D-shaped anti-scratch portion 221 can fit on the outer surface of the agitator 21, so that the anti-scratch member 22 and the agitator 21 are more compact and stable. The curved wall surface of the D-shaped anti-scratch portion 221 serves as an anti-scratch surface to prevent the agitator 21 from scratching the partition 30.

[0078] Of course, in other alternative embodiments, the anti-scratch portion 221 may also be configured to be circular, spherical, elliptical, semicircular, etc.

[0079] In some embodiments, the anti-scratch member 22 is fixed on the agitator 21 by snapping. The anti-scratch member 22 is fixed on the agitator 21 by snapping, which is convenient for disassembly and assembly, and is not easy to fall off.

[0080] Of course, in other alternative embodiments, the anti-scratch member 22 may also be bonded to the agitator 21 .

[0081] In some embodiments, the anti-scratch member 22 also includes an elastic buckle 222, which is fixedly arranged on the side of the anti-scratch portion 221 away from the partition 30, and a clamping hole 210 is arranged on the agitator 21 to cooperate with the elastic buckle 222; the elastic buckle 222 has a closed contracted state and an open clamping state, when the elastic buckle 222 is inserted into the clamping hole 210, the elastic buckle 222 is in a closed contracted state; when the elastic buckle 222 passes through the clamping hole 210, the elastic buckle 222 is in an outwardly opened clamping state.

[0082] In the above embodiment, the anti-scratch component 22 is designed with an upper elastic buckle 222. During assembly, the elastic buckle 222 is constrained and squeezed by the clip hole 210, shrinking inward to facilitate installation. After the elastic buckle 222 is pressed into place and passes through the clip hole 210, it can restore its deformation under the action of its own elastic force and expand outward to be fastened to the clip hole 210, so that the anti-scratch component 22 is installed more firmly, reliably and stably, and is not easy to fall off even under high temperature conditions or in the event of overturning, collision, etc., and the fixing effect is better.

[0083] In this embodiment, the head of the anti-scratch member 22 is semicircular in feature and is located between the agitator 21 and the partition 30 to prevent scratches. The lower part is a snap-on design to facilitate snapping into the agitator 21 to install and fix the anti-scratch member 22.

[0084] In some embodiments, in combination Figure 4 , Figure 5 , Fig.10 As shown, the elastic buckle 222 includes a V-shaped buckle body 2221 and a support rib 2222 fixedly connected between the middle of the buckle body 2221 and the anti-scratch portion 221 .

[0085] In the above embodiment, the root of the anti-scratch member 22 adopts a V-shaped elastic buckle structure design with beveled chamfers on both sides. The V-shaped buckle body 2221 plays a guiding role, which facilitates the quick installation of the anti-scratch member 22. The V-shaped buckle body 2221 and the middle supporting rib 2222 form a double V-shaped root design, which is firmly and stably fixed and not easy to loosen. Two gap grooves are formed between the V-shaped buckle body 2221 and the middle supporting rib 2222. The set gap grooves facilitate the process of pressing the elastic buckle 222 into the buckle hole 210. The V-shaped buckle body 2221 deforms inwardly for easy assembly. It is also convenient for the V-shaped elastic buckle structure to be reset and fastened to the agitator 21 after being pressed to the bottom.

[0086] Furthermore, in the present embodiment, the elastic buckle 222 of the anti-scratch member 22 is similar to an umbrella shape. The anti-scratch member 22 is made of a temperature-resistant material. The anti-scratch member 22 includes a semicircular head and a V-shaped buckle root. The semicircular head is the anti-scratch portion 221, which is located on the side of the agitator 21 close to the partition 30; the V-shaped buckle root is the elastic buckle 222, which is located on the other side of the agitator 21. In the accompanying drawings of the present embodiment, the semicircular head is installed on the upper part of the agitator 21, and the V-shaped buckle root is located at the lower part of the agitator 21.

[0087] In this embodiment, the side of the semicircular head is designed with a chamfer angle so that the anti-scratch portion 221 can rotate at any angle when in contact with the partition 30. In abnormal situations, only the highest point of the semicircular head will contact the ink on the partition 30 to form point contact, thereby preventing large-scale ink shedding and achieving a better anti-scratch effect.

[0088] In other alternative embodiments, the elastic buckle 222 may also adopt the structural form of a clamping column, one end of which is fixed on the anti-scratch part, and the other end is fixedly provided with a chuck, and a groove for deformation is opened in the middle of the chuck, and the chuck has a closed contracted state and an open clamping state. When the clamping column is inserted into the clamping hole, the chuck is in a closed contracted state to facilitate the penetration and coordination of the clamping column and the clamping hole 210. When the clamping column passes through the clamping hole 210, the chuck expands outward to the clamping state under the action of its own elastic force, and is limited on the clamping hole 210, thereby realizing effective fixation of the anti-scratch component 22 and the agitator body 211.

[0089] Furthermore, the anti-scratch member 22 is in a T-shaped structure as a whole, and a plurality of anti-scratch members 22 are arranged at intervals along the circumferential direction of the stirrer 21. Even if the anti-scratch member 22 contacts the partition 30 in an abnormal situation, the rotation is relatively smooth, and the anti-scratch effect is good. Optionally, the clamping hole 210 provided on the stirrer 21 is a square hole, which can be used to install the anti-scratch member 22 and has a relatively small aperture, so as not to affect the microwave performance.

[0090] In the related art, when the rotating agitator 21 jumps abnormally, the outer circular edge of the agitator 21 may randomly scrape the ink surface of the partition 30. The random scraping has a large contact area and is likely to cause a large area of ​​paint to fall off on the surface of the partition 30. In this embodiment, the anti-scratch member 22 provided can effectively reduce the contact area between the agitator 21 and the partition 30, and the anti-scratch member 22 is made of a soft material and will not scratch the partition 30.

[0091] In some embodiments, a microwave inlet 102 is disposed on the bottom plate 11 of the shell 10, and the stirring device 20 further includes a driving mechanism 23 installed on the outside of the bottom plate 11, the driving mechanism 23 is connected to the stirrer 21, and is suitable for driving the stirrer 21 to rotate; the bottom plate 11 is recessed downward to form a microwave stirring chamber 103, the stirrer 21 is located in the microwave stirring chamber 103, and a partition 30 is embedded in the opening of the microwave stirring chamber 103 toward the cooking cavity 101, for separating the microwave stirring chamber 103 from the cooking cavity 101, and the partition 30 is a ceramic plate or a glass plate.

[0092] In the above embodiment, by arranging the microwave inlet 102 and the stirring device 20 at the bottom of the housing 10, the partition 30 is also correspondingly arranged at the bottom of the housing 10, so that the partition 30 can not only play the role of isolating water vapor, but also play the role of supporting the food to be heated, and one thing has multiple uses. The microwave stirring chamber 103 formed by the bottom plate 11 being recessed downward does not occupy the space of the cooking cavity 101, and it is convenient to install the stirrer 21. Moreover, the partition 30 adopts a ceramic plate or a glass plate, which can effectively isolate water vapor while allowing microwaves to penetrate, and will not affect the heating effect of food. The partition 30 is also provided with an ink surface that can reflect microwaves, so that the microwaves are evenly distributed in the cooking cavity 101.

[0093] Furthermore, in this embodiment, the stirrer body 211 is in the shape of a disk, which is rotatably disposed in the microwave stirring chamber 103, the partition 30 is in the shape of a square plate, which is embedded and mounted on the bottom plate 11 of the housing 10, at least the bottom surface of the partition 30 is an ink surface, and the partition 30 is disposed above the stirrer 21 and has a set gap with the stirrer 21 to avoid interfering with the rotation of the stirrer 21. The scratch-proof member 22 is mounted on the outer circle of the stirrer 21, and the scratch-proof portion 221 is located above the stirrer 21 to prevent the stirrer 21 from scratching the partition 30.

[0094] Furthermore, the driving mechanism 23 includes a driving motor, and the stirrer 21 also includes a stirrer shaft 212, one end of the stirrer shaft 212 is fixedly connected to the stirrer body 211, and the other end is fixedly connected to the output shaft of the driving motor. The driving motor is located outside the housing 10, and the stirrer shaft 212 extends into the microwave stirring chamber 103 and is connected to the stirrer body 211. The driving motor drives the stirrer body 211 to rotate through the stirrer shaft 212.

[0095] Optionally, the stirrer shaft 212 is riveted and fixed to the stirrer body 211. A rotating bracket 40 is provided at the microwave inlet 102, and the rotating bracket 40 is fixed on the bottom plate 11, and is used to support the stirrer 21 to improve the overall balance stability of the stirrer 21. The stirrer 21 is placed on the rotating bracket 40 and is driven to rotate by a driving motor. A fan-shaped opening is made on the outer circle of the stirrer body 211, which is used to stir the microwaves and ensure the uniformity of the microwaves.

[0096] Furthermore, combined with Figures 6 to 9 As shown, the microwave inlet 102 is opened at the center position of the bottom plate 11 (that is, the microwave inlet 102 is opened at the center position of the bottom wall of the microwave stirring chamber 103), the middle part of the bottom plate 11 protrudes upward to form a mounting profile 113, the microwave inlet 102 is opened at the middle position of the mounting profile 113, the rotating bracket 40 is clamped and fixed on the circumferential edge of the microwave inlet 102, and the mounting profile 113 is set to support the rotating bracket 40 and the agitator 21, so that the agitator body 211 and the bottom wall of the microwave stirring chamber 103 have a certain height difference, thereby avoiding the problem that the gap between the agitator 21 and the bottom wall of the microwave stirring chamber 103 is small, and the agitator 21 is easy to scratch the bottom wall of the microwave stirring chamber 103 when rotating.

[0097] Furthermore, combined with Figure 2 , Figures 6 to 9 ,as well as Fig.11 As shown, one or more claws 41 are provided on the circumference of the rotating bracket 40, which are clamped on the edge of the microwave inlet 102. The rotating bracket 40 is fixed on the bottom plate 11 by clamping, which is convenient for disassembly and assembly. The rotating bracket 40 is clamped and fixed on the mounting pressure profile 113 through the mounting pressure profile 113 provided in the middle of the partition 30, which is convenient for installing the stirrer 21.

[0098] It should be noted that, in this embodiment, the rotating bracket 40 is an annular structure, and the inner ring in the middle can allow the agitator shaft 212 to pass through. Optionally, there is a set gap between the inner ring of the rotating bracket 40 and the agitator shaft 212. Through the design of the above gap, not only can microwaves be allowed to enter the microwave stirring chamber 103, but also interference with the rotation of the agitator shaft 212 can be avoided.

[0099] Optionally, combined Figure 8 , Fig. 9 , Fig.11 As shown, the rotating bracket 40 is hollowed out, and a plurality of openings 42 are provided at intervals on the circumference of the rotating bracket 40 . The openings 42 on the rotating bracket 40 allow microwaves to enter the microwave stirring chamber 103 .

[0100] Furthermore, the microwave cooking device further includes a heating tube 50, which is located in the microwave stirring chamber 103 and below the partition 30. The heating tube 50 can evaporate the residual water after cooking for a second time. By arranging the heating tube 50 below the partition 30, bottom heating can be achieved, and residual water after cooking can be evaporated simultaneously, thereby preventing water accumulation in the whole machine.

[0101] Furthermore, the microwave cooking device further comprises a microwave generator and a waveguide box 60, wherein the microwave generator is used to generate microwaves, and the waveguide box 60 is used to transmit the microwaves generated by the microwave generator to the microwave inlet 102. Optionally, the waveguide box 60 is welded and fixed to the rear plate of the housing 10, the inlet end of the waveguide box 60 is connected to the microwave generator, and the outlet end extends to the middle position of the bottom plate 11 of the housing 10, and is connected to the microwave inlet 102 at the middle position of the bottom of the housing 10, so that microwaves enter from the middle of the bottom of the housing 10. The driving motor of the stirring device 20 is installed on the outer side of the bottom wall of the waveguide box 60, and its output shaft passes through the bottom wall of the waveguide box 60 and is fixedly connected to the stirring shaft 212. Optionally, the driving motor is fixed to the bottom wall of the waveguide box 60 by screws. The outlet end of the waveguide box 60 is designed to be open at the top. A microwave outlet 601 is provided on the top wall of the outlet end of the waveguide box 60. The microwave outlet 601 covers and covers the periphery of the mounting profile 113, and the microwave outlet 601 of the waveguide box 60 is sealed with the bottom plate 11 of the shell 10 to prevent microwave leakage.

[0102] In other alternative embodiments, the outlet end of the waveguide box 60 extends to the middle of the top plate of the housing 10 , so that microwaves enter from the top of the housing 10 .

[0103] In some embodiments, the bottom plate 11 includes a reference plane and a first stretching platform 111 and a second stretching platform 112 formed by the reference plane being gradually recessed downward; the first stretching platform 111 is vertically stretched from the reference plane to form an annular mounting groove in which the mounting partition 30 can be embedded; the second stretching platform 112 is obliquely stretched from the first stretching platform 111 to form a microwave stirring chamber 103.

[0104] In the above embodiment, the first stretching platform 111 formed by the downward depression of the reference surface is convenient for embedding the partition 30. Preferably, the partition 30 is a glass plate. After the partition 30 is embedded in the annular mounting groove, the surrounding points of silicone seal are used. The first stretching platform 111 and the reference surface are designed by vertical stretching, so that the side wall of the annular mounting groove is a vertical wall surface, which is convenient for matching with the outer peripheral wall of the partition 30, reducing the movable gap of the partition 30, so that the partition 30 has high stability after being embedded in the annular mounting groove, preventing the partition 30 from shifting and loosening after or during the glue dispensing process, resulting in uneven glue dispensing. The second stretching platform 112 and the first stretching platform 111 are stretched at an inclined surface to facilitate stretching and forming. The second stretching platform 112 and the inclined surface enclose the microwave stirring chamber 103, which is convenient for the installation of components such as the stirrer 21 and the heating tube 50.

[0105] In this embodiment, in order to ensure the sealing performance of the microwave stirring chamber 103, silicone is required to be applied to the edges around the partition 30. In this way, even if water droplets drip onto the partition 30, they will not enter the microwave stirring chamber 103 from the gap between the partition 30 and the bottom plate 11, thereby preventing water vapor from entering the microwave stirring chamber 103 and damaging the stirring device 20 and the waveguide box 60. In addition, a heating tube 50 is provided under the partition 30, and the heating tube 50 can heat the water droplets to prevent a large amount of water from accumulating at the bottom.

[0106] Optionally, in this embodiment, the microwave cooking equipment includes but is not limited to a microwave oven and a microwave steam oven.

[0107] It should be noted that the microwaves of the current micro cooking equipment are mainly introduced from the bottom or the top. In this embodiment, the microwave introduction from the bottom is used as an example for explanation. The microwave inlet 102 and the stirring device 20 are arranged at the bottom of the housing 10, but are not limited to the bottom. The microwave inlet 102 and the stirring device 20 can also be arranged at the top of the housing 10. When the stirring device 20 and the microwave inlet 102 are located at the bottom of the housing 10, the partition 30 is installed on the bottom plate 11 of the housing 10, and the food to be heated by microwaves can be directly placed on the partition 30. The partition 30 can not only isolate water vapor and prevent water vapor from entering the stirring device 20 and the waveguide box 60, but also can hold food. In the microwave cooking device provided in this embodiment, the left and right side walls of the housing 10 are provided with a pressing step, which is used to be installed on a baking tray, and the baking tray is stuck at the left and right pressing steps on both sides of the cavity. The food to be heated by microwaves can be placed on the partition 30 or on the baking tray. When the stirring device 20 and the microwave inlet 102 are located at the top of the housing 10, the partition 30 is correspondingly installed on the top plate of the housing 10. The partition 30 only serves to isolate water vapor, preventing water vapor from entering the stirring device 20 and the waveguide box 60, and preventing air and water leakage. As for the food to be heated by microwave, it can be placed on the middle baking tray.
