Description

Technical Field

[0001] This invention relates to the field of cooking machine technology, and more specifically, to a stirring structure and a cooking machine. Background Technology

[0002] Currently, with the development of cooking technology, existing cooking machines are beginning to incorporate intelligent control technology, using intelligent cooking machines to replace manual stir-frying and automatically feed ingredients, reducing manual operation. Meanwhile, to ensure even mixing and stir-frying of ingredients, current technology typically employs electric stirring devices. These devices use a motor to drive the stirrer to rotate, allowing the ingredients to be heated and stir-fried evenly. The stirring paddle's rotating shaft can be designed to be vertical or horizontal.

[0003] However, when the stirring paddle is set horizontally and positioned on the top cover of the stir-fry machine, it may stop at any angle within the 360-degree rotation direction of its axis when the lid is opened. This can result in food sticking to the paddle, requiring the user to remove it, leading to a poor user experience. Additionally, some horizontal stirring methods do not require 360-degree rotation of the paddle; they only need to oscillate left and right along the axis to stir-fry the food. However, this oscillation has positional requirements, meaning the paddle must rotate within the angle covered by the inner pot during stirring, further increasing the likelihood of food sticking to the paddle. Summary of the Invention

[0004] The main objective of this invention is to provide a stirring structure and a stir-fry machine to prevent food from sticking to the stirring paddle of existing stir-fry machines after stirring.

[0005] To achieve the above objectives, according to one aspect of the present invention, a stirring structure is provided for being disposed on the cover of a cooking machine to stir materials located in the pot of the cooking machine. The stirring structure includes: a stirring paddle for rotatably mounted on the cover; a driving assembly connected to the stirring paddle to drive the stirring paddle to rotate; and a detection assembly including a detection component and a positioning component. The positioning component is disposed on the stirring paddle to move with the stirring paddle, and the detection component is disposed on one side of the stirring paddle and fixedly disposed relative to the cover. The detection component cooperates with the positioning component to determine whether the stirring paddle is within a predetermined dwell range by detecting the position of the positioning component, and controls the stopping time of the driving assembly according to the detection result of the detection component so that the stirring paddle remains within the predetermined dwell range after stirring is completed.

[0006] Furthermore, the detection component is a Hall sensor, and the positioning component is a magnetic component.

[0007] Furthermore, the detection component is a laser emitter, and the positioning component is a laser receiver. The laser receiver has a laser receiving part for receiving the laser light emitted by the laser emitter, and the laser receiving part extends around the rotation axis of the stirring paddle.

[0008] Furthermore, both ends of the stirring paddle have rotating shafts, and the stirring paddle is rotatably mounted on the cover via the rotating shafts. A positioning component is fixedly mounted on the rotating shaft at one end of the stirring paddle. The positioning component has a detection part, which is located on one side of the axis of the rotating shaft. The detection component matches the detection part to detect the position of the detection part.

[0009] Furthermore, the positioning component is disposed on the end face of the rotating shaft. The positioning component is cylindrical, and the center line of the positioning component is set at a predetermined detection angle with the axis of the rotating shaft; or the positioning component is disposed on the outer circumferential surface of the rotating shaft.

[0010] Furthermore, the positioning component is disposed on the end face of the rotating shaft. The positioning component is cylindrical, and the center line of the positioning component is perpendicular to the axis of the rotating shaft. The stirring paddle has stirring blades, and the stirring blades have connecting arms for connecting with the rotating shaft. The positioning component is cylindrical, and the angle between the straight line containing the center line of the positioning component and the extension direction of the connecting arm is a first preset angle, which is greater than 0° and less than 90°.

[0011] Furthermore, the end of the rotating shaft is provided with a mounting groove, and at least part of the positioning component is installed in the mounting groove.

[0012] Furthermore, the stirring paddle has a first preset position and a second preset position, and the predetermined dwell range is the range between the first preset position and the second preset position; so that when the stirring paddle is in the first preset position or the second preset position, the angle between the center plane of the stirring paddle and the horizontal plane is greater than 0° and less than or equal to 30°.

[0013] Furthermore, the drive assembly includes: a drive motor; a drive gear connected to the output shaft of the drive motor; and a driven gear meshing with the drive gear, the driven gear being connected to one end of the agitator to drive the drive gear to rotate via the drive motor, thereby causing the agitator to rotate relative to the cover.

[0014] According to another aspect of the present invention, a stir-fry machine is provided, including a stirring structure, which is the stirring structure mentioned above.

[0015] According to the technical solution of this invention, a stirring structure is installed on the lid of a cooking machine to stir materials located inside the pot of the cooking machine. The stirring structure includes a stirring paddle, a driving assembly, and a detection assembly. The stirring paddle is rotatably mounted on the lid. The driving assembly is driven by the stirring paddle to drive the stirring paddle to rotate. The detection assembly includes a detection component and a positioning component. The positioning component is installed on the stirring paddle and moves with the stirring paddle. The detection component is installed on one side of the stirring paddle and fixed relative to the lid. The detection component cooperates with the positioning component to determine whether the stirring paddle is within a predetermined dwell range by detecting the position of the positioning component, and controls the stopping time of the driving assembly according to the detection result of the detection component so that the stirring paddle stays within the predetermined dwell range after stirring is completed. The above configuration involves driving the stirring paddle to rotate relative to the cover via a drive assembly to stir the material inside the pot of the cooking machine. After the material inside the pot is stirred, a positioning component is installed on the stirring paddle. When the stirring paddle drives the positioning component to rotate, a detection component detects the position of the stirring paddle to confirm whether the stirring paddle is within a predetermined stopping range. If the stirring paddle is not within the predetermined stopping range, the detection component controls the drive assembly to drive the stirring paddle to rotate to the predetermined stopping range. This prevents food from sticking to the stirring paddle when the cover is opened, thus preventing the situation in existing cooking machines where food is stuck to the stirring paddle after stirring is completed.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] like Figures 1 to 6 As shown, in the first aspect of the technical solution of the present invention, a stirring structure is used to be disposed on the cover 10 of a cooking machine to stir the material located in the pot 20 of the cooking machine. The stirring structure includes a stirring paddle 30, a driving assembly 40, and a detection assembly 50. The stirring paddle 30 is rotatably mounted on the cover 10. The driving assembly 40 is drivenly connected to the stirring paddle 30 to drive the stirring paddle 30 to rotate. The detection assembly 50 includes a detection component 51 and a positioning component 52. The positioning component 52 is disposed on the stirring paddle 30 and moves with the stirring paddle 30. The detection component 51 is disposed on one side of the stirring paddle 30 and fixedly disposed relative to the cover 10. The detection component 51 cooperates with the positioning component 52 to determine whether the stirring paddle 30 is within a predetermined dwell range S1 by detecting the position of the positioning component 52, and controls the stopping time of the driving assembly 40 according to the detection result of the detection component 51 so that the stirring paddle 30 stays within the predetermined dwell range S1 after stirring is completed.

[0028] Applying the technical solution of this embodiment, the driving component 40 drives the stirring paddle 30 to rotate relative to the cover 10 to stir the material in the pot 20 of the cooking machine. After the stirring of the material in the pot 20 is completed, since the positioning component 52 is set on the stirring paddle 30, when the stirring paddle 30 drives the positioning component 52 to rotate, the detection component 51 detects the position of the stirring paddle 30, thereby confirming whether the stirring paddle 30 is within the predetermined dwell range S1. If the stirring paddle 30 is not within the predetermined dwell range S1, the detection component 51 controls the driving component 40 to drive the stirring paddle 30 to rotate into the predetermined dwell range S1. Therefore, when the cover 10 is opened, there will be no food hanging on the stirring paddle 30, thus preventing the situation in the prior art cooking machine where there is food hanging on the stirring paddle 30 after stirring is completed.

[0029] In this embodiment, the detection component 51 is a Hall sensor, and the positioning component 52 is a magnetic component. The positioning component 52 is fixedly mounted on the stirring paddle 30, and the detection component 51 is mounted on the cover 10 relative to the positioning component 52. When the stirring paddle 30 drives the magnetic component to rotate, the Hall sensor detects changes in the magnetic field of the magnetic component, thereby confirming whether the stirring paddle 30 remains within a predetermined dwell range S1. This prevents food from sticking to the stirring paddle 30 when the cover 10 is opened. If the Hall sensor detects that the stirring paddle 30 is not within the predetermined dwell range S1, the Hall sensor controls the dwell time of the drive assembly 40, causing the drive assembly 40 to drive the stirring paddle 30 to rotate within the predetermined dwell range S1. This ensures that after the material in the pot 20 is stirred, no food remains on the stirring paddle 30.

[0030] Optionally, the detection component 51 is a laser emitter, and the positioning component 52 is a laser receiver. The laser receiver has a laser receiving section for receiving the laser light emitted by the laser emitter, and the laser receiving section extends around the rotation axis 31 of the stirring paddle 30. In the above configuration, the laser receiving section is provided with a preset receiving range so that when the laser receiver emits laser light towards the laser receiving section of the laser receiver, it can be confirmed whether the laser light is within the preset receiving range. If the laser light is within the preset receiving range, the stirring paddle 30 stops within the predetermined stopping range S1; otherwise, if the laser light is not within the preset receiving range, the stirring paddle 30 does not stop within the predetermined stopping range S1. If the laser emitter detects that the emitted laser light is not within the preset receiving range, it controls the drive assembly 40 to drive the stirring paddle 30 to rotate into the predetermined stopping range S1 and stop.

[0031] like Figures 4 to 6As shown, the stirring paddle 30 has a rotating shaft 31 at both ends. The stirring paddle 30 is rotatably mounted on the cover 10 via the rotating shaft 31. The positioning component 52 is fixedly mounted on the rotating shaft 31 at one end of the stirring paddle 30. The positioning component 52 has a part to be detected, which is located on one side of the axis of the rotating shaft 31. The detection component 51 matches the part to be detected to detect the position of the part to be detected. In the above configuration, the positioning component 52 is mounted on the stirring paddle 30, and the part to be detected on the positioning component 52 is located on one side of the axis of the rotating shaft 31. The stirring paddle 30 is driven to rotate by the driving component 40, thereby causing the part to be detected on the positioning component 52 to rotate along the axis of the rotating shaft 31. The detection component 51 detects the change in the part to be detected. At the same time, the position of the stirring paddle 30 is obtained and it is confirmed whether the stirring paddle 30 stops within the predetermined stopping range S1. Based on the detection result, the detection component 51 controls the stopping time of the driving component 40 so that the stirring paddle 30 stops within the predetermined stopping range S1 after the stirring operation is completed, thereby preventing food from sticking to the stirring paddle 30.

[0032] Optionally, the positioning component 52 is disposed on the end face of the rotating shaft 31. The positioning component 52 is cylindrical, and its centerline is set at a predetermined detection angle with the axis of the rotating shaft 31. In this configuration, the positioning component 52 is a laser receiver. The laser receiving part of the laser receiver extends around the rotation axis 31 of the rotating shaft 31 and is set at a predetermined detection angle with the rotation axis 31 of the rotating shaft 31. When the driving assembly 40 drives the stirring paddle 30 to rotate, the positioning component 52 changes position under the drive of the stirring paddle 30, so that the detection component 51 detects whether the emitted laser light is within the preset receiving range on the laser receiving part, thereby confirming whether the stirring paddle 30 stays within the predetermined dwell range S1.

[0033] Optionally, the positioning component 52 is disposed on the outer peripheral surface of the rotating shaft 31; in this way, the position of the positioning component 52 changes when the stirring paddle 30 rotates, so as to determine whether the position of the stirring paddle 30 is within the predetermined dwell range S1 based on the position change of the positioning component 52 detected by the detection component 51.

[0034] Specifically, the positioning component 52 is disposed on the end face of the rotating shaft 31. The positioning component 52 is cylindrical, and the center line of the positioning component 52 is perpendicular to the axis of the rotating shaft 31. The stirring paddle 30 has stirring blades 32, and the stirring blades 32 have connecting arms 321 for connecting with the rotating shaft 31. The positioning component 52 is cylindrical, and the angle between the straight line containing the center line of the positioning component 52 and the extension direction of the connecting arm 321 is a first preset angle, and the first preset angle A1 is greater than 0° and less than 90°. In the above configuration, the positioning component 52 is a magnetic component, which is cylindrical. The center line of the positioning component 52 is fixedly mounted on the rotating shaft 31 perpendicular to the axial direction of the rotating shaft 31, and the first preset included angle is greater than 0° and less than 90°. When the driving assembly 40 drives the stirring paddle 30 to rotate, since the positioning component 52 is in a state of being on a different axis relative to the stirring paddle 30, the detection component 51 can sense the positional change of the positioning component 52 during the synchronous rotation process of the stirring paddle 30 driving the positioning component 52, thereby determining the orientation of the stirring paddle 30 at this time, and further confirming whether the stirring paddle 30 is within the predetermined dwell range S1.

[0035] like Figures 4 to 6 As shown, a mounting groove 310 is provided at the end of the rotating shaft 31, and at least a portion of the positioning component 52 is installed in the mounting groove 310. The mounting groove 310 is rectangular to allow the columnar positioning component 52 to be embedded within it. Furthermore, arc-shaped grooves are provided on both sides of the opening of the mounting groove 310 to facilitate the removal and replacement of the positioning component 52 by personnel.

[0036] Specifically, the stirring paddle 30 has a first preset position W1 and a second preset position W2, and a predetermined dwell range S1 is the range between the first preset position W1 and the second preset position W2; so that when the stirring paddle 30 is in the first preset position W1 or the second preset position W2, the angle between the center plane of the stirring paddle 30 and the horizontal plane is greater than 0° and less than or equal to 30°. In the above configuration, the angle between the center plane of the stirring paddle 30 and the horizontal plane is required to be greater than the angle of repose of the food (i.e., the angle between the food and the horizontal plane). Furthermore, through measurement, under the action of oil, the angle between the center plane of the stirring paddle 30 and the horizontal plane is greater than 0° and less than or equal to 30°. Therefore, the angle between the position of the center plane of the stirring paddle 30 when it is in the first preset position W1 and the position of the center plane of the stirring paddle 30 when it is in the second preset position W2 is 30° to 150°; wherein, the first preset position W1 and the second preset position W2 are respectively located on both sides of the cover 10. When the angle between the driving component 40 and the horizontal direction is greater than 0° and less than or equal to 30°, that is, when the driving component 40 is not within the predetermined dwell range S1, the dwell time of the driving component 40 is controlled by the detection component 51. After the stirring of the material in the pot 20 is completed, the driving component 40 drives the driving component 40 to rotate the driving component 30 to the predetermined dwell range S1. At this time, the angle between the driving component 30 and the horizontal direction is between 30° and 150°, so that when the lid 10 of the cooking machine is opened, there will be no food stuck on the driving component 30.

[0037] like Figure 4 As shown, the drive assembly 40 includes a drive motor 41, a drive gear 42, and a driven gear 43. The drive gear 42 is connected to the output shaft of the drive motor 41. The driven gear 43 meshes with the drive gear 42 and is connected to one end of the stirring paddle 30, so that the drive motor 41 drives the drive gear 42 to rotate, thereby causing the stirring paddle 30 to rotate relative to the cover 10. The aforementioned color and value, by driving the drive gear 42 to rotate via the drive motor 41, causes the driven gear 43 to rotate, which in turn causes the stirring paddle 30 to rotate relative to the cover 10 and stir the material located within the pot body 20.

[0038] In this embodiment, the rotational speed of the magnet component can be sensed by a Hall sensor to roughly assess the amount of food added. Under the same voltage, a faster rotation speed of the drive motor 41 indicates a smaller amount of food being stirred, and vice versa. The Hall sensor can also sense whether the magnet component is installed, and whether the stirring paddle is installed. If it is detected that it is not installed, the cover 10 is closed and the user is warned or reminded to put on the cover 10. Furthermore, the drive motor 41 can drive the stirring paddle 30 to rotate in both directions to adapt to different cooking needs.

[0039] In a second aspect of the technical solution of the present invention, the cooking machine includes a stirring structure, which is the stirring structure mentioned above.

[0040] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0041] A stirring structure is installed on the lid of a cooking machine to stir materials inside the pot. The stirring structure includes a stirring paddle, a drive assembly, and a detection assembly. The stirring paddle is rotatably mounted on the lid. The drive assembly is driven by the stirring paddle to drive it to rotate. The detection assembly includes a detection component and a positioning component. The positioning component is mounted on the stirring paddle and moves with it. The detection component is located on one side of the stirring paddle and fixed relative to the lid. The detection component cooperates with the positioning component to determine whether the stirring paddle is within a predetermined dwell range by detecting the position of the positioning component. Based on the detection result of the detection component, the stopping time of the drive assembly is controlled so that the stirring paddle remains within the predetermined dwell range after stirring is completed. The above configuration involves driving the stirring paddle to rotate relative to the cover via a drive assembly to stir the material inside the pot of the cooking machine. After the material inside the pot is stirred, a positioning component is installed on the stirring paddle. When the stirring paddle drives the positioning component to rotate, a detection component detects the position of the stirring paddle to confirm whether the stirring paddle is within a predetermined stopping range. If the stirring paddle is not within the predetermined stopping range, the detection component controls the drive assembly to drive the stirring paddle to rotate to the predetermined stopping range. This prevents food from sticking to the stirring paddle when the cover is opened, thus preventing the situation in existing cooking machines where food is stuck to the stirring paddle after stirring is completed.
