Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to an anti-shake microwave stirrer component and a microwave oven. Background Art

[0002] With the continuous advancement of microwave oven technology, consumers are placing increasingly high demands on the user experience. As a common appliance in home kitchens, the core function of microwave ovens is to heat food using microwaves. To ensure even distribution of microwaves within the oven cavity, microwave ovens are often equipped with an agitator. The agitator rotates, evenly dispersing the microwaves within the oven cavity, ensuring uniform heating of the food.

[0003] However, in the prior art, in order to ensure the smooth rotation of the stirrer, lubricating silicone grease is usually applied to the contact point between the bottom of the stirrer and the stirrer bracket. However, this lubrication method has the following obvious drawbacks:

[0004] First, the lubricating silicone grease will gradually dry out after a long period of use, which will greatly reduce its lubricating performance, and then make the stirrer rotate poorly, affecting the uniform distribution of microwaves and the heating effect of food.

[0005] Second, if too much silicone grease is applied, the dried silicone grease may increase the vibration of the stirrer and even cause the stirrer to rub against the bottom plate or ceramic plate in the cavity during rotation, generating sparks and unusual noises, which is the so-called "sparking" phenomenon. This phenomenon not only affects the normal operation of the microwave oven, but also poses a threat to the safety of the user.

[0006] Third, the lubricating silicone grease needs to be replaced regularly, which increases the user's maintenance cost and time cost, resulting in a poor user experience.

[0007] Therefore, it is necessary to propose a new anti-shake device to overcome the defects of the existing technology and improve the use effect and user experience of the microwave oven. Utility Model Content

[0021] Furthermore, the anti-shake gasket is integrally formed from a low-friction coefficient material.

[0022] Furthermore, a first limiting groove is provided at the uppermost end of the shaft sleeve for overlapping and fixing the agitator, and the upper end surface of the anti-shake gasket is flush with the lower surface of the first limiting groove.

[0038] In existing microwave ovens, silicone grease is often applied between the stirrer and the bracket to ensure smooth rotation, but this has numerous drawbacks. The grease dries over time, reducing its lubrication properties and hindering the stirrer's rotation, affecting even microwave distribution and food heating. Excessive grease drying can also increase stirrer vibration, causing friction with the inner wall of the oven, resulting in sparks and unusual noises, posing a safety risk to users.

[0039] Based on this, Figures 1 to 3 As shown, the present application discloses an anti-vibration microwave stirrer assembly, comprising:

[0040] A drive motor 1 is used to provide power for the rotation of the stirrer 4;

[0041] A shaft sleeve 3, one end of which is connected to the rotating shaft 2 of the driving motor 1, and the other end is connected to the stirrer 4;

[0042] an anti-shake gasket 6, which is provided at the lower end of the stirrer 4 and can rotate integrally with the stirrer 4;

[0043] The stirrer bracket 5 is fixed to the upper surface of the bottom plate 7 in the cavity to support the anti-shake gasket 6.

[0044] The present application discloses an anti-vibration microwave stirrer assembly, which is powered by a drive motor 1. The drive motor's rotating shaft 2 is connected to one end of a shaft sleeve 3, and the other end of the shaft sleeve 3 is connected to a stirrer 4, thereby achieving power transmission and enabling the stirrer 4 to rotate and disperse the microwaves in the oven cavity. An anti-vibration gasket 6 is provided at the lower end of the stirrer 4, which rotates integrally with the stirrer 4. During operation, the stirrer bracket 5 is firmly fixed to the cavity bottom plate 7 in the microwave oven cavity, providing stable support for the anti-vibration gasket 6. Due to the presence of the anti-vibration gasket 6, the direct friction originally occurring between the stirrer 4 and the stirrer bracket 5 is greatly reduced, and is replaced by friction between the anti-vibration gasket 6 and the stirrer bracket 5. This change effectively reduces the vibration of the stirrer 4 during operation and improves the overall operational stability.

[0045] The anti-vibration microwave oven stirrer assembly disclosed in the present application introduces an anti-vibration gasket design that rotates integrally with the stirrer. The anti-vibration gasket serves as a buffer layer between the stirrer and the stirrer bracket, effectively absorbing the vibration generated when the stirrer is running, reducing the noise and component wear that may be caused by vibration, extending the service life of the microwave oven, and significantly improving the stability and safety of the microwave oven during use.

[0046] As a preferred example of the present application, the anti-vibration gasket 6 includes a gasket body 601, with a through-groove 603 provided at the center of the gasket body 601. The through-groove 603 is sleeved on the outside of the shaft sleeve 3. As a specific example of the present application, the gasket body 601 is arranged in a circular ring shape, and the ratio of the outer diameter of the gasket body 601 to the inner diameter of the gasket body 601 is in the range of 1.5 to 10. This design optimizes the structure of the anti-vibration gasket 6. On the one hand, it enables the anti-vibration gasket 6 to be tightly sleeved on the outside of the shaft sleeve 3, thereby achieving a stable connection between the anti-vibration gasket 6 and the shaft sleeve 3. On the other hand, it also increases the contact area between the anti-vibration gasket 6 and the agitator 4. When the drive motor 1 is started and transmits power to the agitator 4 through the rotating shaft 2 and the shaft sleeve 3, the anti-vibration gasket 6 rotates together with the agitator 4 and the shaft sleeve 3. The design of the through groove 603 not only ensures that the anti-shake gasket 6 can fit tightly against the shaft sleeve 3, but also provides it with a stable support point, so that the anti-shake gasket 6 can always maintain the correct position during operation, effectively isolating the direct friction between the agitator 4 and the agitator bracket 5, thereby achieving the effect of reducing vibration and wear.

[0047] As a preferred example of the present application, the anti-vibration gasket 6 is interference-fitted with the shaft sleeve 3. By making the inner diameter of the through-groove 603 on the anti-vibration gasket 6 slightly smaller than the outer diameter of the shaft sleeve 3, a certain preload force is generated between the two after assembly. This not only enhances the connection strength between the anti-vibration gasket 6 and the shaft sleeve 3, but also ensures that the anti-vibration gasket 6 always clings to the shaft sleeve 3 during operation, effectively isolating the agitator 4 from direct friction with the agitator bracket 5, thereby achieving the design goal of reducing vibration and wear.

[0048] As a preferred example of the present application, a flange 602 bent to one side is provided at the outer edge of the gasket body 601. Correspondingly, a first support portion 502 is provided on the agitator bracket 5. The first support portion 502 is provided on the inner side of the flange 602 for supporting the gasket body 601.

[0049] This setting further optimizes the structure of the anti-shake gasket 6. Through the design of the flange 602, a precise positioning point is provided for the first support part 502 to support the gasket body 601, ensuring its stability during operation. At the same time, the presence of the flange 602 makes the connection between the anti-shake gasket 6 and the agitator bracket 5 more secure, and can maintain a stable support effect even under high-speed rotation and long-term use, avoiding noise and component wear caused by shaking.

[0050] As a preferred example of the present application, the side surface of the first supporting portion 502 contacting the gasket body 601 is an arc surface.

[0051] This design helps transform the frictional contact between the anti-shake pad 6 and the agitator support 5 from surface contact to line contact. During agitator operation, the arc surface design ensures that only the arc vertex of the first support portion 502 contacts a line segment of the pad body 601, significantly reducing the contact area. This not only reduces frictional resistance but also makes the contact more precise and stable, effectively preventing the anti-shake pad 6 from shifting due to vibration or external forces, thereby ensuring that the anti-shake pad 6 can always effectively perform its anti-shake and wear-reducing functions.

[0052] As a preferred example of the present application, a first transition arc 604 is provided at at least one end surface of the gasket body 601 where the through groove 603 is formed, and a second transition arc 605 is provided at the connection between the flange 602 and the gasket body 601. As a preferred example of the present application, a first transition arc 604 is provided at both end surfaces of the gasket body 601 where the through groove 603 is formed. Through the above design, stress concentration caused by vibration or external force can be effectively dispersed and alleviated, avoiding damage or deformation of the gasket body 601 and the flange 602 due to uneven force, ensuring the overall structural strength and stability of the gasket body 601, and improving the durability and reliability of the product.

[0053] As a preferred example of the present application, the anti-shake gasket 6 is made of a one-piece low-friction coefficient material. In the example of the present application, since friction is generated between the anti-shake gasket 6 and the agitator bracket 5 during use, the anti-shake gasket 6 is designed to be one-piece low-friction coefficient material, thereby minimizing the friction between the anti-shake gasket 6 and the agitator bracket 5. During use, the contact surface between the anti-shake gasket 6 and the agitator bracket 5 can effectively reduce the friction resistance and wear between the two, just like lubricating silicone grease, due to the low friction properties of the material itself, thereby ensuring the smooth operation and long-term stability of the agitator. In the example of the present application, the low-friction coefficient material can be plastic or metal, or other materials. Preferably, the low-friction coefficient material is any one of polytetrafluoroethylene (PTFE), silicone rubber, polyethylene, polycarbonate (PC), polyphenylene sulfide, polymethyl methacrylate, and polyvinyl alcohol.

[0054] As a preferred example of the present application, the first support portion 502 is provided on the side of the agitator bracket 5 close to the shaft sleeve 3, and the first support portion 502 is provided on the side of the bracket body 503 close to the anti-shake gasket 6. A first clamping portion 501 facing away from the anti-shake gasket 6 is provided on the side of the bracket body 503 away from the shaft sleeve 3. The first clamping portion 501 is used for snap-fitting the agitator bracket 5 with the bottom plate 7 in the cavity. This arrangement further optimizes the structure of the agitator bracket 5. The ingenious arrangement of the first support portion 502 not only provides stable support for the anti-shake gasket 6, but also ensures a close fit with the shaft sleeve 3, thereby improving the overall stability and operating accuracy of the agitator. At the same time, the design of the first clamping portion 501 enables the agitator bracket 5 to be easily and firmly connected to the clamping groove 701 on the bottom plate 7 in the cavity, greatly simplifying the installation and disassembly process and improving work efficiency.

[0055] This design makes the structure of the stirrer bracket 5 more compact and reasonable, which not only improves the overall performance of the product, but also reduces production costs and maintenance difficulty.

[0056] In the example of the present application, a first limiting groove 301 is provided at the uppermost end of the sleeve 3 for overlapping and fixing the agitator 4, and the upper end surface of the anti-vibration gasket 6 is flush with the lower surface of the first limiting groove 301. In the example of the present application, the uppermost end of the sleeve 3 is cleverly designed with a first limiting groove 301, and the main function of this limiting groove is to overlap and fix the agitator 4. During the installation process, the agitator 4 will be accurately placed in the first limiting groove 301, thereby ensuring its stable connection with the sleeve 3. At the same time, the anti-vibration gasket 6 is carefully sleeved and installed on the sleeve 3, and its upper end surface is precisely adjusted to be flush with the lower surface of the first limiting groove 301. Such a design not only ensures the stability of the agitator 4 during operation, but also further improves the overall performance of the agitator through the effective shock-absorbing effect of the anti-vibration gasket 6. When the agitator starts working, the anti-vibration gasket 6 can absorb and disperse the vibration generated during the agitation process, thereby ensuring that the agitator 4 maintains a stable and smooth operation within the first limiting groove 301. In the example of the present application, the arrangement in which the upper end surface of the anti-vibration gasket 6 is slightly lower than the lower surface of the first limiting groove 301 is also within the scope of protection of the present application.

[0057] The anti-vibration microwave stirrer assembly described in the present application introduces an anti-vibration gasket design that rotates integrally with the stirrer. During actual use, the microwave oven is started, and the turntable motor (drive motor 1) - that is, the rotating shaft 2 rotates normally, driving the shaft sleeve 3, and the shaft sleeve 3 drives the stirrer 4. The anti-vibration gasket 6 is clamped to the shaft sleeve 3 by an interference fit, so it also rotates; while the stirrer bracket 5 is fastened to the inner hole (clamping groove 701) of the bottom plate 7 in the cavity by a hook and does not rotate itself. At this time, the friction should occur between the anti-vibration gasket 6 and the stirrer bracket 5. The anti-vibration gasket 6 acts as a buffer layer, effectively absorbing the vibration generated by the stirrer 4 during operation. By selecting a low friction coefficient material to prepare the anti-vibration gasket 6, the friction between the anti-vibration gasket 6 and the stirrer bracket 5 is minimized, thereby improving the operating efficiency of the stirrer 4 and avoiding the problem of lubrication failure. At the same time, the supporting structure design of the anti-vibration gasket 6 increases the contact area with the stirrer 4 and improves stability.

[0058] The present application also discloses a microwave oven, on which is provided the microwave oven stirrer assembly with anti-vibration as described in the above embodiment. In the examples of the present application, other structures of the microwave oven are known in the prior art and will not be described in detail here.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
