It is understood that the shaft 230 may be directly connected to the perturbation 210 or may be detachably connected. When the rotating shaft 230 is detachably connected with the disturbing member 210, the convenient detachment is realized, the cleaning and maintenance are facilitated, the food safety is realized, and the detachment of the disturbing member 210 is simple. When the rotating shaft 230 is directly connected with the disturbing member 210, i.e. is not detachable, the rotating shaft 230 and the disturbing member 210 are rotationally stable.

As shown in fig. 6, in some embodiments, the at least one bearing includes a first bearing 240, the first bearing 240 being located at a first end of the shaft 230; the socket body 110 includes a fitting portion 130, and the first bearing 240 is fitted to the fitting portion 130.

In this embodiment, the base body 110 is a structure of the base assembly 100 with high stability, and the shaft 230 itself has a first end facing the base body 110. By providing the first bearing 240 at the first end of the rotating shaft 230 and providing the mounting portion 130 adapted to the first bearing 240 on the seat body 110, the stable seat body 110 can be utilized nearby to provide stable and reliable position limitation and support for the first bearing 240, which not only helps to simplify the structure, but also improves the overall structural stability of the perturbation assembly 10.

It should be understood that the first bearing 240 is located at the first end of the rotating shaft 230, and does not mean that the first bearing 240 is located at the end surface of the first end of the rotating shaft 230, but means that the first bearing 240 is located near the first end of the rotating shaft 230, and the end surface facing the outside of the rotating shaft 230 may be flush with the end surface of the first end of the rotating shaft 230, may also protrude from the end surface of the first end of the rotating shaft 230, and may also be lower than the end surface of the first end of the rotating shaft 230. When at least two first bearings 240 are located at the first end of the rotating shaft 230, the at least two first bearings 240 are spaced apart along the axial direction of the rotating shaft 230, wherein there is one first bearing 240, which is located closest to the first end of the rotating shaft 230 and farthest from the second end of the rotating shaft 230, and this first bearing 240 should satisfy the positional relationship description, and is located close to the first end of the rotating shaft 230.

Further, the base assembly 100 further includes a first buffer member connected to the assembling portion 130, and the first buffer member abuts against the rotating assembly 200. By providing the first buffer member in the housing assembly 100, one side of the first buffer member is connected to the assembling portion 130, and the other side of the first buffer member abuts against the rotating assembly 200, so that a buffering effect is achieved between the assembling portion 130 and the rotating assembly 200, and the buffering effect is helpful for buffering the impact caused by the relative movement of the assembling portion 130 and the rotating assembly 200. Through alleviating the collision between the rotating component 200 and the assembling part 130 when the rotating component 200 vibrates, the structural damage caused by long-term collision is avoided, the service life of the disturbance component 10 is prolonged, the vibration noise is reduced, and the use comfort of the product is improved.

Specifically, the first buffer member is a buffer spring. The buffer spring is simple to obtain, simple in structure, convenient to install and small in occupied space. When the buffer spring is abutted against the rotating shaft 230 in the rotating assembly 200, an annular protrusion may be disposed on the outer side wall of the rotating shaft 230 at a side abutted against the rotating shaft 230, the annular protrusion is connected to the buffer spring, the annular protrusion is used for limiting the position of the buffer spring, a movement space of the buffer spring from the annular protrusion of the rotating shaft 230 to the inside of the assembling portion 130 is realized, and a buffering effect of the buffer spring between the rotating shaft 230 and the assembling portion 130 is realized.

As shown in fig. 6, in some embodiments, at least one of the bearings is a first bearing 240, and the number of the first bearings 240 is at least two.

In this embodiment, at least one of the bearings includes only the first bearing 240, i.e. all the bearings are disposed at the first end of the rotating shaft 230, so that the structure of the second end of the rotating shaft 230, which extends into the cooking cavity away from the base body 110, is simple, which helps to reduce the exposure of the bearings in the cooking environment, thereby reducing the cleaning burden of the disturbing assembly 10 and improving the food safety. On the other hand, the structure for limiting the movement range of the bearing in the base assembly 100 can be simplified, that is, only the assembling portion 130 needs to be arranged, and the second end of the rotating shaft 230 does not need to be provided with a limiting structure, so that the overall structure of the disturbance assembly 10 can be simplified, the material can be saved, and the appearance of the disturbance assembly 10 can be attractive.

Further, since the bearing is only disposed at the first end of the rotating shaft 230, so that the rotating shaft 230 forms a cantilever structure, at this time, in order to meet the load requirement of the rotating shaft 230, the first bearing 240 is required to have a sufficiently large acting area, that is, a contact area between the first bearing 240 and the rotating shaft 230, and the inner diameter of the first bearing 240 is limited by the shaft diameter of the rotating shaft 230, at this time, if only one first bearing 240 is disposed, it is required to ensure that the first bearing 240 has a sufficient axial length, and the standard component bearing cannot meet the requirement, so that the mold is required to be opened again to manufacture the non-standard component. By setting the number of the first bearings 240 to be at least two, at least two standard parts can be directly adopted for matching, and the at least two first bearings 240 are distributed at intervals along the axial direction of the rotating shaft 230, so that the product cost can be reduced under the condition of ensuring that the load requirement is met.

In one embodiment, as shown in fig. 6, the pivot assembly 200 is designed to be detachable from the base assembly 100 by a single-sided dual-bearing fixed structure, i.e., at least one bearing comprises two first bearings 240, and the pivot assembly 200 is detachably connected to the base assembly 100.

In some embodiments, the rotating assembly 200 is detachably connected to the mounting portion 130.

Specifically, when the cooking appliance needs to cook high-starch-content food such as rice and porridge, the rotating assembly 200 is mounted on the base assembly 100, and the rotating assembly 200 disturbs the airflow in the cooking cavity, so that at least the food is heated more uniformly and bubbles are prevented from overflowing in a large amount. When the starch content of the food material is low or the cooking treatment requirement is low, the rotating assembly 200 is detached, so that the use of the cooking appliance is not influenced.

After the cooking utensil finishes cooking, the rotating assembly 200 can be cleaned independently by detaching the rotating assembly 200 from the base assembly 100, so that the food safety is guaranteed. When the rotating assembly 200 contacts water vapor and bubbles in the process of disturbing the airflow and causes the rotating assembly 200 to be contaminated with a small amount of food materials or water vapor, the rotating assembly 200 is detached from the base assembly 100, i.e., the rotating assembly 200 is separated from the base assembly 100, so that the rotating assembly 200 can be cleaned independently, the rotating assembly 200 is kept clean, and the food safety is ensured.

As shown in fig. 6, in some embodiments, the mounting portion 130 includes a mounting hole 132 and a stopping portion 134, and the first bearing 240 is fitted into the mounting hole 132; the stopping portion 134 is connected to the assembling hole 132, and the stopping portion 134 is used for axial limitation of the rotating shaft 230.

In this embodiment, the fitting portion 130 includes a fitting hole 132 capable of fitting with the first bearing 240 and a stopper portion 134 capable of defining the axial position of the rotating shaft 230. By providing the assembly hole 132, an accommodation space can be provided for the rotation shaft 230, and an end portion of the rotation shaft 230 far away from the interference member 210 can be inserted into the assembly hole 132, which helps to achieve stable rotation of the rotation shaft 230. The stopping portion 134 connected to the assembling hole 132 is disposed to limit the axial movement range of the rotating shaft 230 relative to the assembling hole 132, so as to limit the rotating assembly 200 along the axial direction of the rotating shaft 230 and enhance the stable rotation of the rotating assembly 200. That is, the fitting hole 132 performs a horizontal direction limit of the rotating assembly 200, and the stopper 134 performs an axial direction limit of the rotating assembly 200.

It can be understood that, when the housing assembly 100 includes the first buffering member, the first buffering member may be disposed in the assembling hole 132 of the assembling portion 130, that is, one side of the first buffering member facing the inside of the housing body 110 is connected to the assembling hole 132, and the other side of the first buffering member faces the outside of the housing body 110 and interferes with the rotating assembly 200, so that the rotating assembly 200 and the housing body 110 are buffered, the installation is simple, and the space is saved. The first buffering member can be further arranged on the outer side of the whole assembling portion 130, one side of the first buffering member is connected with the outer side of the assembling portion 130, the other side of the first buffering member is abutted to the rotating assembly 200, the first buffering member is installed outside the assembling portion 130, buffering of the whole assembling portion 130 and the rotating assembly 200 is achieved through the first buffering member, and buffering effect is good.

The first buffer member can also contact with the first bearing 240, the first bearing 240 supports the rotating shaft 230, and the first bearing 240 buffers, so as to buffer the rotating shaft 230.

As shown in fig. 8 and 9, in some embodiments, a difference obtained by subtracting the inner diameter of the first bearing 240 from the outer diameter of the rotation shaft 230 is greater than or equal to 0.05mm and less than or equal to 2mm, and a difference obtained by subtracting the outer diameter of the first bearing 240 from the inner diameter of the fitting hole 132 is greater than or equal to 0.03mm and less than or equal to 1 mm.

In this embodiment, the outer diameter of the rotating shaft 230 is slightly larger than the inner diameter of the first bearing 240, so that the rotating shaft 230 and the first bearing 240 are in an interference fit, and the rotating shaft 230 and the first bearing 240 are more reliably connected and prevented from being loosened. The internal diameter of pilot hole 132 slightly is greater than first bearing 240, realizes pilot hole 132 and first bearing 240's clearance fit for pilot hole 132 and first bearing 240 realize dismantling the connection, and the pivot 230 of being convenient for is dismantled, is washd and is changed, and that is to say, assembly 130 and runner assembly 200 have realized dismantling the connection, can dismantle whole runner assembly 200 from assembly 130, and the cleaning of the runner assembly 200 of being convenient for guarantees the health of eating the material.

It can be understood that, the difference between the outer diameter of the rotating shaft 230 and the inner diameter of the first bearing 240 is between 0.05mm and 2mm, which can ensure an interference fit, the connection between the rotating shaft 230 and the first bearing 240 is more reliable, and when the difference between the two is less than 0.05mm, a stable interference fit cannot be realized, when the difference between the two is greater than 2mm, the interference value is too large, which easily causes the problem that the installation cannot be performed or the installation is laborious, the difference between the outer diameter of the rotating shaft 230 and the inner diameter of the first bearing 240 is limited to be greater than or equal to 0.05mm, and is less than or equal to 2mm, so that the reliable assembly between the rotating shaft 230 and the first bearing 240 is realized.

When the difference between the inner diameter of the assembly hole 132 and the outer diameter of the first bearing 240 is less than 0.03mm, the assembly hole 132 and the first bearing 240 are connected too tightly, so that the disassembly is difficult; when the assembly hole 132 and the first bearing 240 are larger than 1mm, the gap between the assembly hole 132 and the first bearing 240 is too large and is easy to loosen, and the difference range is larger than or equal to 0.03mm and smaller than or equal to 1mm, so that the gap fit between the assembly hole 132 and the first bearing 240 is ensured, and the reliable connection is realized.

As shown in fig. 6 and 7, in some embodiments, a difference obtained by subtracting the outer diameter of the rotation shaft 230 from the inner diameter of the first bearing 240 is equal to or greater than 0.03mm and equal to or less than 1mm, and a difference obtained by subtracting the inner diameter of the fitting hole 132 from the outer diameter of the first bearing 240 is equal to or greater than 0.05mm and equal to or less than 2 mm.

In this embodiment, the inner diameter of the first bearing 240 is slightly larger than the outer diameter of the rotating shaft 230, so as to realize clearance fit, facilitate the detachment and installation between the first bearing 240 and the rotating shaft 230, and achieve the detachable connection between the rotating assembly 200 and the base assembly 100, and the detached rotating assembly 200 does not include the first bearing 240, so that the detached structure can be simplified, the cleaning by a user is facilitated, and the sanitation of food materials is ensured. The outer diameter of the first bearing 240 is larger than the inner diameter of the assembly hole 132, so that the first bearing 240 and the assembly hole 132 are in interference fit, the first bearing 240 and the assembly hole 132 are stably connected, and the assembly is reliable.

It can be understood that, the inside diameter of the first bearing 240 and the outside diameter difference of the rotating shaft 230 are in the range from 0.03mm to 1mm, which can ensure the clearance fit, the detachable connection between the rotating shaft 230 and the first bearing 240 is realized, the rotating shaft 230 is convenient to detach, when the difference between the two is less than 0.03mm, the rotating shaft 230 and the first bearing 240 are too tight, the installation and the detachment are time-consuming and labor-consuming, when the difference between the two is greater than 1mm, the clearance is too large, and the bearing is easy to fall off.

When the difference of the inside diameter of the external diameter of the first bearing 240 minus the assembly hole 132 is less than 0.05mm, stable interference fit cannot be realized, resulting in unstable connection, when the difference between the external diameter of the first bearing 240 and the inside diameter of the assembly hole 132 is greater than 2mm, the external diameter of the first bearing 240 is too large, resulting in the problem of incapability of mounting or labor waste in mounting, and easily causing damage to the first bearing 240.

The assembly hole 132 can also be a blind hole, and the axial limiting of the rotating assembly 200 is realized by directly utilizing the bottom wall of the blind hole, so that the structure is simplified, the stability of the rotating assembly 200 is realized, meanwhile, the first bearing 240 is prevented from being polluted, the cleaning of the first bearing 240 is realized, the supporting reliability of the first bearing 240 is improved, and the service life of the first bearing 240 is prolonged.

Specifically, at least one of the bearings may include both the second bearing 250 and the first bearing 240, and when the first bearing 240 is included, the seat body 110 includes the assembling portion 130, so that the first end and the second end of the rotating shaft 230 are simultaneously supported, and the rotating shaft 230 is separated from the cantilever state, which can sufficiently improve the overall structural stability of the perturbation assembly 10. For example, in one embodiment, as shown in fig. 12, the pivot assembly 200 is a double-sided fixed bearing seal non-removable structure, i.e., at least one bearing comprises a first bearing 240 and a second bearing 250, and the pivot assembly 200 is fixedly coupled to the housing assembly 100.

In other embodiments, the shaft 230 is in a clearance fit with the first bearing 240, and the assembly hole 132 is in a clearance fit with the first bearing 240.

It should be understood that the second bearing 250 is located at the second end of the rotating shaft 230, and does not mean that the second bearing 250 is located at the end surface of the second end of the rotating shaft 230, but means that the second bearing 250 is located near the second end of the rotating shaft 230, and the end surface facing the outside of the rotating shaft 230 may be flush with the end surface of the second end of the rotating shaft 230, may protrude from the end surface of the second end of the rotating shaft 230, or may be lower than the end surface of the second end of the rotating shaft 230.

When the buffer spring is abutted against the rotating shaft 230 in the rotating assembly 200, an annular protrusion can be arranged on the outer side wall of the rotating shaft 230 on the side abutted against the rotating shaft 230, the annular protrusion is connected with the buffer spring, the annular protrusion is used for limiting the position of the buffer spring, the buffer spring is enabled to move in the limiting part 142 from the annular protrusion of the rotating shaft 230, and the buffer effect of the buffer spring between the rotating shaft 230 and the limiting part 142 is achieved.

In some embodiments, the connecting portion 144 is fixedly connected with the socket body 110.

As shown in fig. 12, in some embodiments, the connecting portion 144 extends from an end connected to the position-limiting portion 142 toward the seat body 110, and is inclined in a direction away from the axis of the rotation shaft 230.

In this embodiment, to ensure the reliable connection between the seat body 110 and the limiting portion 142 away from the seat body 110, the connecting portion 144 needs to extend along the length direction of the rotating shaft 230. By limiting the connecting portion 144 to be inclined in a direction deviating from the axis of the rotating shaft 230 in the extending direction from the limiting portion 142 to the seat body 110, a sufficient space can be left between the connecting portion 144 and the rotating shaft 230 to provide the disturbing member 210, while ensuring reliable connection, and safe operation of the disturbing member 210 is ensured.

It can be understood that the connecting portion 144 only needs to exhibit the inclination trend as a whole, and the extending direction does not need to be inclined everywhere, for example, as shown in fig. 12, the connecting portion 144 can extend along the length direction of the rotating shaft 230 for one section without inclination, and then incline again, which is the same as the implementation manner of the present invention, and falls within the protection scope of the present invention.

Specifically, the size and number of the connecting portions 144 can be set appropriately in combination with the support requirements and the spoiler requirements to achieve an optimized overall effect.

It can be understood that, when the connecting portions 144 are extended along the length direction of the rotating shaft 230 for a certain period without being inclined as shown in fig. 12, and then inclined again, the parts of the connecting portions 144 that are not inclined can be connected with each other as shown in fig. 14, so as to ensure that the gap is left and improve the stability of the connection.
