Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

Examples:

as shown in fig. 1, 2 and 3, the rotating assembly provided in this embodiment includes a support rod 1, a sleeve 2, a first magnet 20 and a second magnet 10; the sleeve body 2 is sleeved outside the support rod 1, the first magnet 20 is arranged on the sleeve body 2, the second magnet 10 is arranged on the support rod 1, the first magnet 20 and the second magnet 10 are opposite in position, and one sides, close to each other, of the first magnet 20 and the second magnet 10 repel each other, so that a gap is reserved between the inner wall of the sleeve body 2 and the outer wall of the support rod 1.

The rotating assembly provided by the embodiment can be applied to cooking appliances such as a steaming oven, and can be matched with electric elements such as a detection device, a circuit board and a programmable logic controller which are preset on the cooking appliances. In the rotating assembly provided in this embodiment, the first magnet 20 and the second magnet 10 are opposite to each other, and the sides of the first magnet 20 and the second magnet 10 that are close to each other repel each other, so that the sleeve 2 can be suspended after being mutually repelled from the support rod 1 under the repulsive action of the first magnet 20 and the second magnet 10, and a space is always kept between the sleeve 2 and the support rod 1. The magnetic poles of the first magnet 20 and the second magnet 10 that are close to each other are homopolar, and specifically, may be both N poles or both S poles.

When the rotating assembly is required to rotate to adjust parameters such as the gear, the cooking function and the like of the cooking appliance, the sleeve body 2 can be rotated, after the sleeve body 2 is rotated, the rotating angle and the rotating direction of the sleeve body 2 can be detected by the detecting device, then the detecting device can send detection information to the control assembly such as the circuit board or the programmable logic controller, and the control assembly correspondingly adjusts parameters such as the gear, the cooking function and the like of the cooking appliance according to the received information.

It can be seen that the rotating assembly provided in this embodiment uses the repulsive interaction of the magnets, so that the sleeve body 2 and the support rod 1 are always spaced, thus forming the sleeve body 2 capable of suspending, so that no friction exists between the sleeve body 2 and the support rod 1, and the service life and the times of the rotating assembly can be effectively prolonged.

Compared with the prior art, the rotating assembly provided by the embodiment enables the sleeve body 2 to be suspended on the supporting rod 1 through the first magnet 20 and the second magnet 10 which are oppositely arranged and mutually repulsed, so that the sleeve body 2 and the supporting rod 1 are always provided with a space, when the sleeve body 2 is rotated to adjust the parameters of the rotating assembly, friction is not generated between the sleeve body 2 and the supporting rod 1, and the service life of the rotating assembly can be prolonged.

As shown in fig. 4, a first sensing member 11 is disposed at a position of the support rod 1 facing the inner wall of the sleeve body 2, and a plurality of sensed members are disposed on the inner wall of the sleeve body 2 in sequence along the circumferential direction thereof; or, the inner wall of the sleeve body 2 is provided with a first induction piece 11, and a plurality of induction pieces which are distributed in turn along the circumferential direction of the support rod 1 are arranged at the position facing the inner wall of the sleeve body 2; the first sensing element 11 is used for sensing an element to be sensed to detect the rotation direction and the rotation angle of the sleeve body 2 when the sleeve body 2 rotates.

In this embodiment, the first sensing element 11 is preferably disposed on the support rod 1, and the sensed element is disposed on the sleeve body, where the detecting device that is used in cooperation with the sleeve body 2 and the support rod 1 in this embodiment is the first sensing element 11, and in the rotating process of the sleeve body 2, the first sensing element 11 rotates relative to a plurality of sensed elements on the support rod 1, and at this time, the first sensing element 11 can determine the rotating direction and the rotating angle of the sleeve body 2 by sensing the number of sensed elements or by sensing the time passing through a plurality of sensed elements.

In practical application, the rotation angle of the sleeve body 2 can be identified by combining the number of the sensed members sensed by the first sensing member 11 with the included angle between two adjacent sensed members. The rotation direction of the sleeve body 2 can be identified by the time used by the sensing pieces in the preset quantity through the first sensing pieces 11, specifically, the included angle between every two adjacent sensing pieces can be sequentially increased or decreased along the circumferential direction of the sleeve body 2, and at the moment, the rotation direction of the sleeve body 2 can be judged by the time used by the sensing pieces in the preset quantity through the first sensing pieces 11.

In this embodiment, the first sensing element 11 may be a hall sensor, and the corresponding sensed element is the first magnet 20.

Alternatively, the first sensing element 11 may be an infrared sensor, and the sensed element may be a groove or a perforation provided on the inner wall of the sleeve body 2.

As shown in fig. 5 and 6, a second sensing piece 12 is arranged at a position of the support rod 1, which is positioned outside the sleeve body 2, and a sensed piece is arranged on the sleeve body 2; or the sleeve body 2 is provided with a second sensing piece 12, and a sensed piece is arranged at the position of the support rod 1, which is positioned outside the sleeve body 2; the second sensing element 12 is used for sensing the sensed element to detect the axial moving direction of the sleeve body 2 when the sleeve body 2 moves along the axial direction thereof.

In this embodiment, the second sensing element 12 is preferably disposed on the support rod 1, and the sensed element is disposed on the sleeve 2. When the first sensing member 11 is disposed on the support rod 1, the sensed member may have the same structure as the sensed member that can be sensed by the first sensing member 11.

Because the sensed member is located in the sensing range of the second sensing member 12, when the sleeve body 2 slides on the support rod 1 along the axial direction of the sleeve body 2, the sensing result of the second sensing member 12 sliding with the sleeve body 2 on the sensed member changes, so that the sleeve body 2 is detected to slide on the support rod 1, and the specific axial moving direction of the sleeve body 2 can be judged through the change of the distance between the second sensing member 12 and the sensed member.

The specific axial moving direction of the sleeve body 2 includes two directions, wherein one direction is a direction when the sleeve body 2 moves close to one end of the supporting rod 1, and the other direction is a direction when the sleeve body 2 moves close to the other end of the supporting rod 1. Taking the support rod 1 as a horizontal rod and two ends of a horizontal plate being respectively positioned at the left side and the right side of the support rod 1 as an example, the axial moving direction of the sleeve body 2 comprises two directions of leftward sliding and rightward sliding.

The rotating assembly in this embodiment can be used for switching functions such as fire adjustment and time adjustment of the cooking appliance, and can be used for adjusting gears of parameters such as fire and time of the cooking appliance, and correspondingly, axial movement of the sleeve body 2 in this embodiment is associated with the function switching operation of the cooking appliance, and rotation of the sleeve body 2 is associated with the gears of parameters such as fire and time of the cooking appliance.

Specifically, a function switching and gear adjusting program is preset on control components such as a circuit board, a programmable logic controller and the like. The function that the rotating assembly originally controlled can be firepower gear adjusting function, when adjusting cooking utensil's firepower gear and time gear, can rotate the cover body 2 under firepower gear adjusting function, first response piece 11 can mutually support and detect the rotation angle and the direction of rotation of cover body 2 by the response piece this moment, and then control assembly can adjust cooking utensil's firepower size according to the testing result of first response piece 11. After the firepower gear of the cooking utensil is adjusted to the place, the sleeve body 2 is slid leftwards on the supporting rod 1, at the moment, the second sensing piece 12 can be mutually matched with the sensed piece to detect that the sleeve body 2 slides leftwards, then the control component can switch the function of the cooking utensil controlled by the rotating component according to the detection result of the second sensing piece 12, the function of the cooking utensil controlled by the rotating component is switched from the last function to the next function, for example, the firepower gear is adjusted to the time gear, then the sleeve body 2 can be moved to the original position, and the first sensing piece 11, the sensed piece and the control component are mutually matched to adjust the cooking time of the cooking utensil again by rotating the external member.

After the time gear is adjusted in place, the sleeve body 2 can also be slid rightwards, at this time, the second sensing piece 12 can be matched with the sensed piece to detect that the sleeve body 2 slides rightwards, then the control component can switch the function of the cooking appliance controlled by the rotating component according to the detection result of the second sensing piece 12, and switch the function of the cooking appliance controlled by the rotating component from the next function back to the previous function, for example, switch the time gear adjustment to the fire gear adjustment.

It should be noted that, because the sleeve body 2 is suspended on the supporting rod 1 and the sleeve body 2 can axially move on the supporting rod 1, the daily cleaning process of the supporting rod 1 cannot be affected by the sleeve body 2, and the use experience of a user can be effectively improved.

As shown in fig. 6, there may be two second sensing elements 12, where two second sensing elements 12 are both disposed at positions of the support rod 1 outside the sleeve body 2, and one of the second sensing elements 12 is disposed at one side of one end of the sleeve body 2, and the other second sensing element 12 is disposed at one side of the other end of the sleeve body 2.

The two second sensing elements 12 are respectively used for being matched with the sensed element close to the second sensing element to detect that the sleeve body 2 slides leftwards and rightwards, and compared with the case that only one second sensing element 12 is used for detecting that the sleeve body 2 slides leftwards or rightwards, the detection result of the two second sensing elements 12 is more accurate.

In this embodiment, the second sensing member 12 may also employ a hall sensor.

As shown in fig. 4, the first magnets 20 and the second magnets 10 are plural, the plural first magnets 20 are sequentially distributed along the circumferential direction of the sleeve body 2, the plural second magnets 10 are wound on the shaft of the support rod 1, and the plural first magnets 20 and the plural second magnets 10 are distributed in one-to-one correspondence.

When the first sensing element 11 is a hall sensor, the plurality of first magnets 20 are used to form a plurality of sensed elements, so as to facilitate the detection of the rotation angle of the sleeve body 2 by cooperating with the first sensing element 11.

In addition, the plurality of first magnets 20 and the plurality of second magnets 10 are distributed in a one-to-one correspondence, so that repulsive force between the magnets can be distributed more uniformly between the support rod 1 and the sleeve body 2, and the suspension stability of the sleeve body 2 on the support rod 1 is improved.

Further, the plurality of first magnets 20 may be equally spaced along the circumferential direction of the sleeve body 2, and the plurality of second magnets 10 may be equally spaced along the circumferential direction of the support rod 1.

The equally spaced distribution can further promote the uniformity of the distribution of the repulsive force between the magnets, thereby further promoting the suspension stability of the sleeve body 2.

In the present embodiment, the rotation direction of the sleeve body 2 is divided into a forward rotation direction and a reverse rotation direction, and the magnetic force of the plurality of first magnets 20 sequentially increases or the magnetic force of the plurality of second magnets 10 sequentially increases along the forward rotation direction of the sleeve body 2.

The forward rotation direction and the reverse rotation direction are not particularly limited as long as the forward rotation direction and the reverse rotation direction are opposite to each other, for example, when the forward rotation direction is a clockwise rotation direction, the reverse rotation direction is a counterclockwise rotation direction.

Along the forward direction of the sleeve body 2, when the magnetic force of a plurality of first magnets 20 or a plurality of second magnets 10 increases in sequence, the rotating force can be gradually increased when the sleeve body 2 is rotated, so that damping sense is generated, a user experiences a feel of a pause, and the user experience is further improved.

As shown in fig. 4, the plurality of sensed members are equally spaced apart.

When a plurality of inducted pieces are distributed at equal intervals, the included angles between every two adjacent inducted pieces are equal, so that the specific rotation angle of the sleeve body 2 can be calculated according to the number of the inducted pieces detected by the first inducted pieces 11 in the rotation of the sleeve body 2.

Since it is difficult to determine the rotation direction of the sleeve body 2 according to one first sensing element 11 when the plurality of sensed elements are distributed at equal intervals, in this embodiment, the number of the first sensing elements 11 is preferably two, and the two first sensing elements 11 are symmetrically distributed on the support rod 1 with the central axis of the support rod 1 as a symmetry axis.

In the rotating process of the sleeve body 2, the two first sensing pieces 11 can be matched with a plurality of sensed pieces to generate phase differences, so that the control assembly can conveniently recognize the reverse rotation of the sleeve body 2.

As shown in fig. 7, the support bar 1 in this embodiment is a handle bar on a door body 3 of a cooking appliance.

In addition, the knob of the conventional cooking appliance is usually mounted beside the display area, and when the knob is rotated, the display area around the knob is easily covered, which is not beneficial for a user to rotate the knob and observe information on the display screen.

The sleeve body 2 of the rotating assembly provided in this embodiment is assembled on the handle bar of the cooking appliance, and in view of the fact that the handle bar of the cooking appliance such as the steaming oven is a component with higher frequency of use of the whole machine and is generally located below the information display area, the rotating assembly provided in this embodiment is convenient for a user to operate the sleeve body 2 and observe information on the display screen without shielding.

It should be noted that, when the knob of the existing cooking appliance is used, the force exerted by the wrist of the user applies a force rotating leftwards or rightwards to the knob, and in view of the physiological characteristics of the wrist, the process of rotating the knob by the force exerted by the wrist is inconvenient, which is not beneficial to rapid operation.

But the rotating assembly that this embodiment provided will cover body 2 assemble on cooking utensil's handle pole, when rotatory cover body 2, only need the user to grasp the handle pole and utilize the finger to exert a force again to rub the rotation of cover body 2 can realize cover body 2, and this rotatory cover body 2's process is similar to the gyro wheel operation on the mouse, uses more convenient, also does benefit to fast operation.

As shown in fig. 7, this embodiment further provides a cooking apparatus, which includes the above-mentioned rotating assembly, so that the cooking apparatus provided in this embodiment and the above-mentioned rotating assembly can solve the same technical problem, achieve the same technical effect, and are not described herein again.

It should be noted that, the cooking appliance is generally equipped with a control assembly, and when the rotating assembly further includes the first sensing member 11 and the sensed member, the control assembly is connected with the first sensing member 11, and the control assembly is preset with a plurality of functional parameter gears divided according to the rotating direction and the rotating angle of the sleeve body 2.

The first sensing element 11 can sense the sensed element to detect the rotation direction and rotation angle of the sleeve body 2 when the sleeve body 2 rotates, and the control assembly is used for receiving the rotation direction information and rotation angle information of the sleeve body 2 and adjusting the functional parameters of the cooking appliance under the current function to corresponding functional parameter gears according to the rotation direction information and rotation angle information. The functions of the cooking appliance include, but are not limited to, fire adjustment and time adjustment, and the corresponding functional parameters include, but are not limited to, fire parameters and time parameters.

When the rotating assembly further comprises a second sensing piece 12, the control assembly is connected with the second sensing piece 12, and a plurality of functional gears for dividing the axial moving direction of the root sleeve body 2 are preset in the control assembly.
