Description

Technical Field

[0001] This application relates to the field of cooking equipment technology, and in particular to stir-fry machines. Background Technology

[0002] A cooking machine is an intelligent device that automates the cooking process, automatically heating oil, stirring, and controlling the heat. It not only performs multiple functions in one pot, such as stir-frying, pan-frying, cooking, deep-frying, quick-frying, braising, steaming, boiling, grilling, stewing, and simmering, but also truly achieves smokeless cooking, saving time, effort, and hassle, and preventing sticking, burning, and overflowing.

[0003] Stir-fry machines typically have a rotating blade inside the pot to stir-fry the ingredients. However, different ingredients have different stirring requirements. For example, different ingredients require different heights between the blade and the bottom wall of the cooking cavity. Furthermore, some ingredients rotate with the blade and require it to move up and down to improve stirring efficiency. Other ingredients, such as tofu, are too fragile to be stirred with a blade that moves up and down. Current stir-fry machines have a single, unadjustable blade rotation method, failing to meet the needs of different ingredients. Summary of the Invention

[0004] Therefore, it is necessary to provide a new type of stir-fry machine to address the problems of existing stir-fry machines having a single rotating blade mode, being inconvenient to adjust, and being unable to meet the needs of different ingredients.

[0005] A stir-fry machine includes a base, a pot body, and an adjustment assembly. The base houses a drive assembly comprising a rotation drive component and a drive shaft. The rotation drive component is configured to rotate the drive shaft. One end of the drive shaft, away from the rotation drive component, protrudes from the base and is configured to move axially relative to the base along the drive shaft. The pot body is detachably connected to the base. The pot body contains a stirring assembly comprising a connected stirring blade and a stirring shaft coaxially arranged with the drive shaft. When the pot body is connected to the base, the stirring shaft is drive-connected to the drive shaft. The stirring shaft is configured to rotate relative to the pot body and move axially along the stirring shaft. A retaining member is provided on the peripheral wall of the stirring shaft. A bottom wall of the pot body has a track surrounding the stirring shaft and aligned with the retaining member. The track includes a top surface with a height difference along the axial direction of the stirring shaft. The retaining member abuts against the top surface and moves along the top surface when the stirring shaft rotates. The adjustment component acts on the drive shaft and is configured to drive the drive shaft to move along its axial direction.

[0006] In one embodiment, when the abutment moves along the top surface, the maximum undulation stroke of the stirring shaft caused by the movement of the stirring shaft in the axial direction of the stirring shaft is equal to the maximum height difference of the top surface, which is L1. The maximum lifting stroke of the adjustment component that can drive the drive shaft to move in the axial direction of the drive shaft is L2, where L2 ≥ L1.

[0007] In one embodiment, the interior of the pot body is provided with a cooking cavity and a transition cavity that are arranged vertically and spaced apart. The bottom wall of the cooking cavity is provided with a through hole to connect the cooking cavity and the transition cavity. The stirring blade is located in the cooking cavity. The stirring shaft passes through and slides in the through hole. The end of the stirring shaft away from the stirring blade protrudes from the pot body. The track is located on the bottom wall of the transition cavity.

[0008] In one embodiment, the stirring assembly further includes a reset elastic element, which is sleeved on the outer periphery of the stirring shaft and has a tendency to drive the stirring shaft toward the base.

[0009] In one embodiment, the adjustment assembly includes a moving drive and a moving member, the moving drive acting on the moving member and driving the moving member to move axially along the drive shaft, the drive shaft being on the moving path of the moving member as it moves axially along the drive shaft toward the stirring assembly and abutting against the moving member.

[0010] In one embodiment, the drive assembly further includes a clamping elastic element that acts on the drive shaft and has a tendency to move the drive shaft toward the stirring shaft along its own axial direction, and the elastic force of the clamping elastic element is less than the elastic force of the reset elastic element.

[0011] In one embodiment, the cooking machine further includes a bearing housing, the bearing housing having a rotating hole arranged axially along the stirring shaft. The bearing housing is axially movable within the through hole, and the stirring shaft and the bearing housing abut against each other in the axial direction of the stirring shaft to move synchronously. The return spring abuts against the bottom wall of the cooking cavity and the bearing housing at both ends in the axial direction of the stirring shaft, and has a tendency to drive the bearing housing toward the drive assembly. The stirring shaft is rotatably inserted through the rotating hole, and the outer peripheral surface of the bearing housing abuts against the wall of the through hole in the circumferential direction.

[0012] In one embodiment, the cooking machine further includes a sealing assembly fitted onto the stirring shaft and located within the through hole. The sealing assembly is made of a flexible, deformable material and is pressed radially between the wall of the through hole and the outer periphery of the stirring shaft.

[0013] In one embodiment, the top surface includes alternating highest and lowest positions, with a smooth transition between adjacent highest and lowest positions.

[0014] In one embodiment, there are multiple abutment members, and the abutment members are symmetrically distributed around the axis of the stirring shaft. The top surface includes multiple arc surfaces that correspond one-to-one with the number of abutment members. All the arc surfaces are connected end to end to form the top surface. All the arc surfaces are symmetrically distributed around the axis of the stirring shaft. The height of each abutment member in different arc surfaces is the same, and each arc surface includes at least one highest position and at least one lowest position.

[0015] In one embodiment, the abutment includes an extension rod and a roller, the extension rod extending radially outward from the peripheral wall of the stirring shaft, and the roller being rotatably connected to the end of the extension rod away from the stirring shaft, the roller abutting against and rollingly connected to the top surface.

[0016] The cooking machine provided in the above solution combines a height adjustment component with a track. By adjusting the height of the stirring blade driven by the adjustment component, the undulation height of the stirring blade caused by the height difference of the top surface is affected. This allows the stirring blade to undulate significantly, slightly, or not at all at different heights, thus enabling a variety of stirring blade rotation patterns to adapt to the stir-frying needs of different ingredients. Moreover, the rotation pattern of the stirring blade can be adjusted simply by adjusting the height of the stirring blade driven by the adjustment component, making adjustment convenient and broadening the practical application scenarios of the cooking machine.

[0028] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0034] See Figure 1 , Figure 1 This illustration shows a structural schematic diagram of a stir-fry machine 100 according to an embodiment of this application. The stir-fry machine 100 includes a base 110, a pot body 130, and a pot lid 180. The pot body 130 is detachably connected to the base 110, and the pot body 130 has a cooking cavity 131 for stir-frying. Figure 2 and Figure 4 As shown, a stirring component 140 is provided inside the pot body 130. The stirring component 140 stirs the ingredients in the cooking cavity 131 by rotating itself. The pot lid 180 is placed on the pot body 130.

[0035] like Figure 2 and Figure 4 In the illustrated embodiment, the pot body 130 also includes a handle 135, which protrudes from the outer wall of the pot body 130 to facilitate picking up and putting down the pot body 130. Figure 2 and Figure 4 In the embodiment shown, the pot body 130 also includes a latch 138. When the pot body 130 is connected to the base 110, the latch 138 engages with the base 110 to fix the pot body 130 and the base 110.

[0036] like Figure 2 and Figure 4 In the illustrated embodiment, the pot body 130 further includes a heating element 136 and a sealing cover 137. The sealing cover 137 is located on the side of the bottom wall of the cooking cavity 131 facing away from the cooking cavity 131. The sealing cover 137 is used to seal the cooking cavity 131 to prevent the soup inside the cooking cavity 131 from leaking out. A space for heating by the heating element 136 is formed between the sealing cover 137 and the bottom wall of the cooking cavity 131. The heating element 136 is connected to the side of the bottom wall of the cooking cavity 131 facing away from the cooking cavity 131 to heat the food inside the cooking cavity 131 through the bottom wall of the cooking cavity 131. In this embodiment, the heating element 136 is a heating tube.

[0037] like Figures 2 to 5 As shown, the base 110 houses a drive assembly 120, which provides power for the rotation of the stirring assembly 140. (Combined) Figures 2 to 5As shown, the drive assembly 120 includes a rotation drive 121 and a drive shaft 122. The rotation drive 121 provides power to the drive shaft 122 and the stirring assembly 140. The rotation drive 121 is configured to drive the drive shaft 122 to rotate. In this embodiment, the rotation drive 121 is a motor. It is understood that the base 110 is also connected to a wire that is electrically connected to the drive assembly 120 to energize the drive assembly 120.

[0038] like Figure 1 As shown, the end of the drive shaft 122 away from the rotation drive member 121 protrudes from the base 110 and is in contrast. Figure 3 and Figure 5 The drive shaft 122 is configured to move relative to the base 110 along the axial direction of the drive shaft 122.

[0039] like Figure 3 As shown, in one embodiment, the rotation drive 121 includes a power source 1211 and an output shaft 1212. The power source 1211 is configured to drive the output shaft 1212 to rotate, and the drive shaft 122 is drively connected to the output shaft 1212 and configured as follows: Figure 3 and Figure 5 The device shown can move relative to the output shaft 1212 along the axial direction of the drive shaft 122.

[0040] like Figure 3 and Figure 5 As shown, in this embodiment, the drive assembly 120 further includes a limiting member 125. One end of the limiting member 125 is detachably connected to the output shaft 1212. The drive shaft 122 is sleeved on the outer periphery of the limiting member 125 so that the drive shaft 122 can move relative to the limiting member 125. The other end of the limiting member 125 has an end face that restricts the drive shaft 122 from moving in a direction away from the power source 1211.

[0041] like Figure 3 and Figure 5 As shown, in this embodiment, the drive assembly 120 further includes a first transmission member 124 connected to the drive shaft 122. The first transmission member 124 is connected to the end of the drive shaft 122 away from the power source 1211, and the first transmission member 124 rotates synchronously with the drive shaft 122. The first transmission member 124 is used to insert into the stirring assembly 140 for transmission connection.

[0042] like Figure 2 and Figure 4As shown, a stirring assembly 140 is provided inside the pot body 130. The stirring assembly 140 includes a stirring blade 141 connected to rotate synchronously and a stirring shaft 142 coaxially arranged with the drive shaft 122. When the pot body 130 is connected to the base 110, the stirring shaft 142 is connected to the drive shaft 122. The stirring shaft 142 is configured to rotate relative to the pot body 130 to drive the stirring blade 141 to rotate and stir the food in the cooking cavity 131. The stirring shaft 142 can also move along the axial direction of the stirring shaft 142 to drive the stirring blade 141 to move up and down.

[0043] like Figure 2 and Figure 4 As shown, in one embodiment, the interior of the pot body 130 is provided with a cooking cavity 131 and a transition cavity 132 that are distributed vertically and spaced apart. The bottom wall of the cooking cavity 131 is provided with a through hole 133 to connect the cooking cavity 131 and the transition cavity 132. The stirring blade 141 is located inside the cooking cavity 131, and the stirring shaft 142 passes through and slides in the through hole 133. The end of the stirring shaft 142 away from the stirring blade 141 protrudes out of the pot body 130.

[0044] like Figure 3 and Figure 5 In the embodiment shown, a second transmission member 146 is provided at one end of the stirring shaft 142 away from the stirring blade 141. The second transmission member 146 is connected to the stirring shaft 142 in a transmission manner, that is, the two rotate synchronously. When the pot body 130 is connected to the base 110, the second transmission member 146 is inserted into the first transmission member 124 of the drive assembly 120 to realize the transmission connection between the stirring shaft 142 and the drive assembly 120.

[0045] like Figure 2 and Figure 4 As shown, the stirring shaft 142 is partially located within the cooking cavity 131 and partially within the transition cavity 132. The peripheral wall of the stirring shaft 142 located in the transition cavity 132 is provided with an abutment member 143 for connection. Figure 6 and Figure 7 As shown, a bottom wall of the pot body 130 is provided with a track 144 that surrounds the stirring shaft 142 and is aligned with the abutment member 143. The track 144 includes a top surface 1441 with a height difference along the axial direction of the stirring shaft 142. The abutment member 143 abuts against the top surface 1441 and moves along the top surface 1441 when the stirring shaft 142 rotates, so that when the stirring shaft 142 rotates, the abutment member 143 can drive the stirring shaft 142 to move along its own axial direction under the action of the top surface 1441. This allows the stirring blade 141 connected to the stirring shaft 142 to move along the axial direction of the stirring shaft 142 while the stirring shaft 142 rotates.

[0046] like Figure 2 and Figure 4As shown, in this embodiment, the track 144 is located on the bottom wall of the transition cavity 132. The transition cavity 132 where the track 144 is located is separated from the cooking cavity 131 used for cooking, thereby avoiding interference of the ingredients with the rotation and up-and-down movement of the stirring blade 141, improving the stability and controllability of the rotation and up-and-down movement of the stirring blade 141, and thus improving the stir-frying effect.

[0047] In one embodiment, the top surface 1441 includes alternating highest positions 1443 and lowest positions 1442, with a smooth transition between adjacent highest positions 1443 and lowest positions 1442 to allow the abutment 143 to move smoothly along the top surface 1441.

[0048] In one embodiment, there are multiple abutment members 143, and the abutment members 143 are symmetrically distributed around the axis of the stirring shaft 142. The top surface 1441 includes multiple arc surfaces with the same number of abutment members 143. All the arc surfaces are connected end to end to form the top surface 1441. All the arc surfaces are symmetrically distributed around the axis of the stirring shaft 142, and each arc surface includes at least one highest position 1443 and at least one lowest position 1442.

[0049] In this embodiment, there are two abutment members 143. The two abutment members 143 are located on the same straight line and extend to both ends relative to the stirring shaft 142. Correspondingly, the top surface 1441 is divided into two arc surfaces arranged in a centrally symmetrical manner. When the abutment members 143 rotate with the stirring shaft 142, the two abutment members 143 are located on the two arc surfaces respectively. When one abutment member 143 is located at the highest position 1443 of the corresponding arc surface, the other abutment member 143 is also located at the highest position 1443 of the corresponding arc surface. When one abutment member 143 is located at the lowest position 1442 of the corresponding arc surface, the other abutment member 143 is also located at the lowest position 1442 of the corresponding arc surface, so that the stirring shaft 142 is subjected to uniform force and avoids the deflection caused by uneven force.

[0050] In one embodiment, the abutment member 143 includes an extension rod 1431 and a roller 1432. The extension rod 1431 extends radially outward from the peripheral wall of the stirring shaft 142. It is understood that the radial outward extension of the extension rod 1431 along the stirring shaft 142 is only a directional limitation. The extension rod 1431 and the stirring shaft 142 can be an integral structure or a fixedly connected separate structure. Furthermore, as... Figure 4 and Figure 5 As shown, the roller 1432 is rotatably connected to the end of the extension rod 1431 away from the stirring shaft 142. In this embodiment, see [reference needed]. Figure 5 The roller 1432 is fixedly connected to the extension rod 1431 via a pivot. For example... Figure 2 As shown, the roller 1432 abuts against and rolls against the top surface 1441.

[0051] In one embodiment, the maximum height difference of the top surface 1441 is L1. When the abutment 143 moves along the top surface 1441, the maximum undulation stroke of the stirring shaft 142 in its own axial direction is equal to the maximum height difference of the top surface 1441, that is, the maximum undulation stroke is L1. In other words, under the action of the top surface 1441, the range of up-and-down undulation of the stirring shaft 142 and the stirring blade 141 is from 0 to L1.

[0052] The stir-fry machine 100 also includes an adjustment component 150, which acts on the drive shaft 122 and is configured to drive the drive shaft 122 to move axially along the drive shaft 122. By driving the drive shaft 122 to move axially, the stirring shaft 142 and the stirring blade 141 connected to the drive shaft 122 are moved axially, thereby adjusting the height of the stirring blade 141 in the cooking cavity 131 to adapt to the stir-frying needs of different ingredients.

[0053] The maximum lifting stroke of the adjustment component 150 that can drive the drive shaft 122 to move axially in the drive shaft 122 is L2, that is, the range of vertical movement of the adjustment component 150 and the stirring shaft 142 is from 0 to L2.

[0054] In this embodiment, the maximum lifting stroke L2 is greater than or equal to the maximum undulation stroke L1. The actual lifting stroke H2 is controlled by the adjustment component 150, which can be freely selected within the range of 0 to L2 during actual lifting. The top surface 1441 has a fixed height difference, and when the contact member 143 contacts the top surface 1441, there will inevitably be undulation stroke caused by the height difference. That is, the size of the actual undulation stroke H1 cannot be directly adjusted, but the actual undulation stroke H1 will be affected by the actual lifting stroke H2.

[0055] However, since the maximum lifting stroke L2 ≥ the maximum undulation stroke L1, the actual lifting stroke H2 and the actual undulation stroke H1 can be in the following three cases:

[0056] 1. H2 = 0. At this time, the adjustment component 150 does not adjust the drive shaft 122 up and down. At this time, the actual undulation stroke H1 caused by the abutment 143 moving along the top surface 1441 on its own axis is equal to the maximum undulation stroke L1. That is, the stirring blade 141 undulates greatly at this time.

[0057] 2.0 < H2 < L1. At this time, the adjusting component 150 drives the drive shaft 122 to move, resulting in an actual lifting stroke H2. Since the stirring shaft 142 moves upward with the drive shaft 122, the abutment 143 connected to the stirring shaft 142 moves upward with the stirring shaft 142. At this time, there is a height difference of H2 between the abutment 143 and the lowest position 1442 of the top surface 1441. When the abutment 143 moves along the top surface 1441, it will not be able to reach the lowest position 1442. Therefore, the abutment 143 moves along part of the top surface 1441. The actual undulation stroke H1 = L1 - H2 caused by this movement of the stirring shaft 142 in its own axial direction is the slight undulation of the stirring blade 141.

[0058] 3. When L1≤H2≤L2, the adjusting component 150 drives the drive shaft 122 to move, resulting in an actual lifting stroke H2≥L1. Since the stirring shaft 142 and the abutment 143 move upward with the drive shaft 122, there is a height difference of 0 or H2-L1 between the abutment 143 and the highest position 1443 of the top surface 1441. At this time, the abutment 143 will not be able to move along the top surface 1441. That is, at this time, the actual undulation stroke H1 of the stirring shaft 142 moving upward in its own axis caused by the top surface 1441 is 0, that is, the stirring blade 141 does not undulate.

[0059] In other embodiments, the maximum lifting stroke L2 may be less than the maximum undulation stroke L1. In this case, the actual lifting stroke H2 and the actual undulation stroke H1 can have two scenarios: large undulation and small undulation of the stirring blade 141 as described above.

[0060] In one embodiment, the adjustment assembly 150 includes a movable drive 151 and a movable member 152. The movable drive 151 acts on the movable member 152 and drives the movable member 152 to move axially along the drive shaft 122. The drive shaft 122 is on the movement path of the movable member 152 as it moves axially along the drive shaft 122 toward the stirring assembly 140 and abuts against the movable member 152, so that when the movable member 152 moves axially along the drive shaft 122 toward the stirring shaft 142, that is, when the movable member 152 moves upward, the drive shaft 122 can move synchronously with the movable member 152. In this embodiment, as... Figure 3 As shown, the movable member 152 is partially clamped between the drive shaft 122 and the output shaft 1212. When the movable member 152 moves upward, it can drive the drive shaft 122 to move upward. When the movable member 152 moves downward, it is limited by the position of the output shaft 1212.

[0061] The moving drive 151 and the rotating drive 121 provide power for the up-and-down movement and rotation of the stirring shaft 142 and the stirring blade 141, respectively. They do not interfere with each other and are controlled independently. The adjusting component 150 can adjust the height of the stirring blade 141 according to the preset menu or manually by the user before the stir-fry machine 100 cooks food, for example after determining the ingredients to be used, to meet the stir-frying requirements of the ingredients. It can also be applied during the cooking process of the stir-fry machine 100, so that the stirring blade 141 of the stir-fry machine 100 has height fluctuations while rotating, thereby improving the stir-frying effect of the stirring blade 141.

[0062] like Figure 3 and Figure 5 As shown, in one embodiment, the moving drive member 151 further includes a transmission rod 153, which is connected to the moving drive member 151 and the moving drive member 151 is configured to drive the transmission rod 153 to move. The moving member 152 is provided with a hole that aligns with the transmission rod 153, and the transmission rod 153 passes through the hole so that the moving member 152 can be sleeved on the outer periphery of the transmission rod 153. A limiting piece 1531 protrudes from the outer periphery of the transmission rod 153. The moving member 152 moves along the axial direction of the limiting piece 1531 along the drive shaft 122 and toward the stirring assembly 140, so that when the transmission rod 153 drives the limiting piece 1531 fixedly connected to the transmission rod 153 to move upward, the moving member 152 and the limiting piece 1531 move synchronously.

[0063] It is understandable that, in cases like Figures 2 to 5 In the embodiment shown, the maximum lifting stroke L2 of the drive shaft 122 that the adjusting component 150 can drive is affected by the movable distance of the transmission rod 153.

[0064] like Figure 3 and Figure 5 As shown, in one embodiment, the base 110 includes a fixing frame 111, which is connected to a wall of the base 110. In this embodiment, the fixing frame 111 is located inside the base 110 and is connected to the top surface 1441 of the inner wall of the base 110. The fixing frame 111 is provided with a threaded hole 1111 arranged along the axial direction of the drive shaft 122. The transmission rod 153 is threadedly connected to the threaded hole 1111. The transmission rod 153 is a transmission screw. The transmission rod 153 moves up and down relative to the fixing frame 111 and the base 110 by rotating relative to the threaded hole 1111.

[0065] In one embodiment, the stirring assembly 140 further includes a reset elastic member 145, which is sleeved on the outer periphery of the stirring shaft 142 and has a tendency to drive the stirring shaft 142 toward the base 110. The functions of the reset elastic member 145 are: 1. to apply downward pressure to the stirring shaft 142 so that the stirring shaft 142 remains in transmission connection with the drive shaft 122; 2. when the moving member 152 in the adjusting assembly 150 moves down, the elastic force of the reset elastic member 145 on the stirring shaft 142 and the drive shaft 122 can drive the drive shaft 122 to move down until the drive shaft 122 abuts against the moving member 152, so as to facilitate the next height adjustment of the stirring shaft 142 and the stirring blade 141 by the adjusting assembly 150.

[0066] In one embodiment, the stir-fry machine 100 further includes a bearing housing 160. The bearing housing 160 has a rotating hole 164 arranged axially along the stirring shaft 142. The bearing housing 160 is axially movably disposed within the through hole 133, and the stirring shaft 142 and the bearing housing 160 abut against each other axially along the stirring shaft 142 to move synchronously. Figure 6 As shown, in this embodiment, the bearing housing 160 includes a first clamping member 161 partially embedded in the circumferential surface of the stirring shaft 142 and a second clamping member 162 partially embedded in the inner wall surface of the bearing housing 160 (i.e., the circumferential wall of the rotating hole 164). The first clamping member 161 and the second clamping member 162 are relatively fixed in the axial direction. The first clamping member 161 is partially embedded in the circumferential surface of the stirring shaft 142 to move axially synchronously with the stirring shaft 142, and the second clamping member 162 is partially embedded in the bearing housing 160 to move synchronously with the bearing housing 160. The stirring shaft 142 and the bearing housing 160 move synchronously in the axial direction through the relatively fixed positions of the first clamping member 161 and the second clamping member 162.

[0067] In this embodiment, the position of the through hole 133 in the bottom wall of the cooking cavity 131 extends along the axial direction of the stirring shaft 142 in a direction away from the cooking cavity 131, forming an annular platform 134 surrounding the through hole 133. Figure 7 As shown, the ring platform 134 is provided with a limiting groove 1341 arranged along the axial direction, and the bearing seat 160 is provided with a guide post 163 adapted to the limiting groove 1341. The guide post 163 extends radially outward from the outer peripheral surface of the bearing seat 160 so that the guide post 163 is partially embedded in the limiting groove 1341. When the bearing seat 160 moves along the axial direction, the guide post 163 slides in the limiting groove 1341 so as to guide the axial movement of the bearing seat 160 through the limiting groove 1341.

[0068] like Figure 5As shown, the stirring assembly 140 also includes a fixing cap 147 detachably connected to the pot body 130. In this embodiment, the fixing cap 147 is connected to the ring platform 134, and the fixing cap 147 covers the through hole 133 and is connected to the bottom wall of the cooking cavity 131 on the side facing away from the cooking cavity 131. In this embodiment, the fixing cap 147 is threadedly connected to the ring platform 134, and the fixing cap 147 has a hole for the stirring shaft 142 to pass through. Figure 5 As shown, the fixing cap 147 is located in the direction of movement of the bearing housing 160 toward the track 144 and has a limiting block that extends inward to limit the movement of the bearing housing 160.

[0069] The stirring shaft 142 is rotatably disposed in the rotating hole 164, and the outer peripheral surface of the bearing seat 160 and the wall of the through hole 133 abut against each other in the circumferential direction to prevent the bearing seat 160 from rotating with the stirring shaft 142, thereby achieving a rotatable arrangement of the stirring shaft 142 relative to the wall of the rotating hole 164. For example, the outer peripheral surface of the bearing seat 160 is provided with protrusions or bumps, and these protrusions or bumps are embedded in the wall of the through hole 133 to achieve a circumferential abutment between the bearing seat 160 and the wall of the through hole 133.

[0070] like Figure 9 As shown, the two ends of the reset spring 145 in the axial direction of the stirring shaft 142 abut against the bottom wall of the cooking cavity 131 and the bearing seat 160, respectively, and have a tendency to drive the bearing seat 160 toward the drive assembly 120. In this embodiment, the reset elastic member 145 is sleeved on the outer periphery of the bearing seat 160, and the hole wall of the through hole 133 extends inward to form a limiting block opposite to the limiting block located on the outer periphery of the bearing seat 160. The two ends of the reset elastic member 145 are clamped between the opposing limiting blocks so as to have a tendency to drive the bearing seat 160 and the stirring shaft 142 toward the drive shaft 122.

[0071] like Figure 3 and Figure 5 As shown, in one embodiment, the drive assembly 120 further includes a clamping elastic member 123, which acts on the drive shaft 122 and has the tendency to drive the drive shaft 122 to move along its own axial direction toward the stirring shaft 142, and the elastic force of the clamping elastic member 123 is less than the elastic force of the reset elastic member 145.

[0072] like Figure 3 and Figure 5As shown, the clamping elastic element 123 is arranged axially along the stirring shaft 142. In this embodiment, the clamping elastic element 123 is a spring. The clamping elastic element 123 is sleeved on the outer periphery of the drive shaft 122, and the drive shaft 122 is provided with a limiting block protruding from its own circumferential surface. The two ends of the clamping elastic element 123 abut against the limiting block and the moving member 152 described below, respectively, so that the clamping elastic element 123 is squeezed between the drive shaft 122 and the moving member 152, and has a tendency to drive the drive shaft 122 toward the stirring assembly 140. The end of the drive shaft 122 away from the driving member is connected to the stirring assembly 140, so that the drive shaft 122 maintains a transmission connection with the stirring assembly 140 under the action of the clamping elastic element 123. In other embodiments, the two ends of the clamping elastic element 123 may also abut against the limiting block and the output shaft 1212, respectively.

[0073] like Figure 9 As shown, in one embodiment, the cooking machine 100 further includes a sealing component 170, which is sleeved on the stirring shaft 142 and located in the through hole 133. The sealing component 170 is made of a flexible and deformable material, such as rubber, and is pressed in the radial direction of the stirring shaft 142 between the hole wall of the through hole 133 and the outer periphery of the stirring shaft 142 to seal the cooking cavity 131 and prevent the food inside the cooking cavity 131 from flowing out.

[0074] like Figure 9 As shown, in one embodiment, the sealing assembly 170 includes a shaft seal ring 171, which is sleeved on the outer periphery of the stirring shaft 142 and is pressed radially between the wall of the rotating hole 164 and the outer periphery of the stirring shaft 142 to seal the gap between the stirring shaft 142 and the bearing seat 160.

[0075] In one embodiment, the sealing assembly 170 includes an outer sealing ring 172, which is fitted around the outer periphery of the bearing housing 160 and is pressed radially between the wall of the through hole 133 and the outer periphery of the bearing housing 160 to seal the gap between the outer periphery of the bearing housing 160 and the wall of the through hole 133.

[0076] The stir-fry machine 100 provided in the above solution, by setting a drive shaft 122 to drive the stirring shaft 142 and the stirring blade 141 located in the cooking cavity 131 to rotate, and cooperating with the adjustment component 150 acting on the drive shaft 122 and driving the drive shaft 122 to move axially, realizes that the stirring blade 141 is driven to move up and down in the cooking cavity 131 by the adjustment component 150; combined with the top surface 1441 of the track 144 having a height difference, the abutment member 143 abuts against the top surface 1441, so that when the stirring shaft 142 rotates, it drives the abutment member 143 to move along the top surface 1441, thereby realizing the up and down movement of the stirring blade 141 located in the cooking cavity 131, and as the stirring shaft 142 rotates, the stirring blade 141 moves up and down. The stirring blade 141 rotates while also exhibiting height variations. The height adjustment component 150, combined with the track 144, allows for adjustable height movement. By adjusting the height of the stirring blade 141 driven by the adjustment component 150, the height variation caused by the height difference between the top surface 1441 and the stirring blade 141 is affected. This allows the stirring blade 141 to exhibit large, small, or no fluctuations at different heights, thus enriching the rotation patterns of the stirring blade 141 to suit the stir-frying needs of different ingredients. Furthermore, the rotation pattern of the stirring blade 141 can be achieved simply by adjusting the height of the stirring blade 141 driven by the adjustment component 150, making adjustment convenient and broadening the practical application scenarios of the cooking machine 100.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
