Description
Technical Field
[0001] The present application relates to the technical field of kitchen utensils, and particularly to a rotary grill and a cooking device. Background Art
[0002] With the improvement of people's living standards and the change of eating habits, baked foods are loved by more and more people, and cooking equipment such as ovens has become one of the essential kitchen appliances in many families. In order to improve the uniformity of food baking, a rotary grill is usually provided in the oven. Most of the rotary grills in the prior art are driven to rotate by a motor. The motor first transmits the rotation to a rotary joint installed in a small hole provided on the inner wall of the oven cavity, and then transmits it to the rotary grill. However, the motor is prone to aging or damage in the high-temperature environment inside the oven, which results in poor reliability and short service life of the rotary grill.
[0003] Therefore, considering other factors, there are few ovens on the market that are equipped with a rotary grill as a functional component. Even if there is a matching one, because the grill for holding the food to be baked is heavy and cumbersome, it is difficult to insert one end of the rotating shaft of the grill into the rotary joint in the small hole on the inner wall of the oven cavity by holding the other end of the rotating shaft, which causes a pain point. Moreover, The base supporting the outer rotating shaft blocks the entrance of the oven, making the whole operation more inconvenient. Summary of the Invention
[0004] The present application provides a rotary grill and a cooking device. The rotary grill is driven purely mechanically and can utilize the heat generated during oven baking to drive the rotary grill to rotate, which can improve the reliability of the rotary grill, extend the service life of the rotary grill, and play a role in saving energy. Further, with the modular creation concept, the rotary grill provided by the present application can be highly integrated with related devices during operation. The rotary grill provided by the present application can be detached from the device (such as an oven) before and after baking, and can form an operating platform independently. Moreover, the rotary basket in the rotary grill provided by the present application has two modes: freely rotating or locked in place, which enables users to easily complete ingredient preparation or directly have a meal. In addition, users can also disassemble the rotary grill provided by the present application into small units by hand to facilitate cleaning and storage.
[0005] In a first aspect, the present application provides a rotary grill. The rotary grill includes a base, a fluid chamber, a fluid, a hydraulic cylinder, a transmission member, and a rotating member. The rotating member is provided on the base and can rotate relative to the base about the axis of the rotating member. The hydraulic cylinder includes a cylinder barrel, a piston, and a piston rod. The piston is provided in the cylinder barrel and can move relative to the cylinder barrel along the axial direction of the cylinder barrel. One end of the piston rod is fixedly connected to the piston, and the other end extends outside the cylinder barrel; the fluid is stored in the fluid chamber. The fluid chamber is connected and communicated with the cylinder barrel. The transmission member is provided on the side of the piston rod facing away from the piston and is connected to the piston rod, and the transmission member is connected to the rotating member. When the temperature of the fluid chamber rises, the fluid expands due to heat and enters the cylinder barrel to drive the piston to move relative to the cylinder barrel along the axial direction of the cylinder barrel, thereby driving the piston rod to move along the axial direction of the cylinder barrel away from the cylinder barrel, and causing the piston rod to drive the transmission member to move, and further causing the transmission member to drive the rotating member to rotate.
[0006] In a possible implementation manner, the rotary grill further includes an input shaft, an output shaft, a first gear, and a second gear.

The first one-way bearing is sleeved on the outer periphery of the input shaft and is located between the input shaft and the first gear, and the first one-way bearing is fixedly connected to the first gear. When the piston rod moves away from the cylinder barrel, the transmission member drives the input shaft to rotate in the forward direction, the input shaft drives the first one-way bearing to rotate in the forward direction, and the first one-way bearing drives the first gear to rotate in the forward direction. When the piston rod moves closer to the cylinder barrel, the transmission member drives the input shaft to rotate in the reverse direction, and the input shaft rotates relative to the first one-way bearing.
[0008] In a possible implementation manner, the rotary grill further includes a connecting shaft sleeve. The connecting shaft sleeve is fixedly connected to the output shaft.

When the first rotating section is mounted in the first connecting cavity, the connecting shaft sleeve locks with the first rotating section, and when the connecting shaft sleeve rotates, it can drive the rotating shaft to rotate.
[0009] In a possible implementation, the rotating shaft further includes a second rotating section. The second rotating section is connected to one end of the first rotating section facing away from the rotating basket. The second rotating section is cylindrical, and the diameter of the second rotating section is smaller than the diameter of the inscribed circle of the first connecting cavity. When the second rotating section is installed in the first connecting cavity, the second rotating section can rotate relative to the connecting bushing within the first connecting cavity.
[0010] In a possible implementation, the rotating member further includes a third rotating section. The third rotating section is connected to one end of the second rotating section facing away from the first rotating section. The third rotating section is installed on the base and can rotate relative to the base. The third rotating section is provided with a first limiting groove and a second limiting groove. Both the first limiting groove and the second limiting groove are arranged circumferentially around the third rotating section, and the first limiting groove and the second limiting groove are arranged at intervals along the axial direction of the rotating shaft. When the first rotating section is installed in the first connecting cavity, the bottom of the first limiting groove supports on the base. When the second rotating section is installed in the first connecting cavity, the bottom of the second limiting groove supports on the base.
[0011] In a possible implementation, the base includes a first bracket, a second bracket, a mounting member, and a locking member. The second bracket includes a supporting portion, a connecting portion, and a sliding portion.

The pressing column and the locking column are fixed on the same surface of the spring piece, and the pressing column and the locking column are arranged at intervals. The spring piece is fixedly connected to the second bracket, and both the pressing column and the locking column face the sliding portion. When the spring piece is in a natural state, the locking column locks the sliding portion; when the pressing column is pressed in a direction away from the sliding portion, the locking column moves in a direction away from the sliding portion and unlocks the sliding portion, and the spring piece is in a deformed state.
[0012] In a possible implementation, the transmission member includes a rack and a transmission gear. The transmission gear is installed on the input shaft and is fixedly connected to the input shaft; the rack is provided on the side of the piston rod facing away from the piston and is fixedly connected to the piston rod, and the rack meshes with the transmission gear.
[0013] In a possible implementation, the transmission member includes a swing arm. The swing arm is connected between the piston rod and the input shaft. One end of the swing arm is rotatably connected to the piston rod, and the other end of the swing arm is fixedly connected to the input shaft.

The mounting wheels are mounted on the output shaft, one end of the pulling rope is fixedly connected to the mounting wheels, and the other end of the pulling rope is fixedly connected to the thermal coupling sheet closest to the bottom plate among the plurality of thermal coupling sheets. When the thermal coupling member is heated, it deforms towards the bottom plate direction, driving the pulling rope to move towards the bottom plate direction, so that the pulling rope drives the mounting wheels to rotate in the forward direction, and the mounting wheels drive the output shaft to rotate in the forward direction, and further the output shaft drives the rotating member to rotate in the forward direction.
[0015] In a possible implementation, the rotary grill further includes a resilient member. One end of the resilient member is fixedly connected to the base, and the other end is fixedly connected to the mounting wheels. When the thermal coupling member is heated and deformed and overall elongated, and drives the mounting wheels to rotate in the forward direction through the pulling rope, the mounting wheels drive one end of the resilient member to rotate, and the resilient member further deforms. After the thermal coupling member cools down, the thermal coupling sheets in the thermal coupling member deform and recover, the thermal coupling member shrinks overall and releases the pulling rope, and the pulling rope loses tension, so that the resilient member drives the mounting wheels to rotate in the reverse direction and winds the pulling rope.
[0016] In a possible implementation, the rotary grill further includes a second one-way bearing; the second one-way bearing is sleeved on the outer periphery of the output shaft and is located between the output shaft and the mounting wheels, and the second one-way bearing is fixedly connected to the mounting wheels. When the thermal coupling member is heated and deformed and overall elongated, and drives the mounting wheels to rotate in the forward direction through the pulling rope, the mounting wheels drive the second one-way bearing to rotate in the forward direction, and the second one-way bearing drives the output shaft to rotate in the forward direction. When the resilient member elastically recovers to drive the mounting wheels to rotate in the reverse direction, the mounting wheels drive the second one-way bearing to rotate in the reverse direction, and the second one-way bearing rotates relative to the output shaft.
[0017] In a possible implementation, the rotary grill further includes a heat insulation sleeve, which is sleeved on the outer periphery of the cylinder barrel.

[0073] When the second bracket 12 is installed on the mounting member 13 and the locking member 14 locks the second bracket 12, the sliding portion 121 is located in the sliding groove 131, the projection of the limit hole 1211 along the X - axis direction overlaps or substantially overlaps with the projection of the avoidance hole 132 along the X - axis direction, and at least a part of the locking column 145 is located in the limit hole 1211 and locks the sliding portion 121. At this time, the second bracket 12 is fixedly connected to the first bracket 11 and jointly supports the rotating assembly 20 of the rotating grill 100.
[0074] The sliding part 121 can be wedged into the mounting part 13. Specifically, during the process of installing the second bracket 12 on the first bracket 11, the end of the sliding part 121 of the second bracket 12 can be inserted into the sliding groove 131 and slide linearly, so that the front edge of the end of the sliding part 121 presses against the head of the locking column 145, thereby causing the locking column 145 to retreat along its axis and move away from the mounting part 13. Further, in this embodiment, the head of the locking column 145 is hemispherical to reduce the friction generated when the front edge of the end of the sliding part 121 presses against the head of the locking column 145.
[0075] When the second bracket 12 continues to slide forward until the projection of the limiting hole 1211 of the sliding part 121 and the avoiding hole 132 of the mounting part 13 overlap in the X-axis direction, the locking column 145 moves into the limiting hole 1211 under the elastic force of the elastic piece 141, connecting the avoiding hole 132 and the limiting hole 1211 to lock the sliding part 121, that is, to lock the second bracket 12.
[0076] When the pressing column 144 is pressed, the pressing column 144 drives the locking column 145 to move away from the mounting part 13 through the rigid part 1413, so that the locking column 145 disengages from the limiting hole 1211 and unlocks the sliding part 121. After the sliding part 121 and the locking column 145 are unlocked, sliding the sliding part 121 along the sliding groove 131 out of the sliding groove 131 can realize the disassembly of the second bracket 12.
[0077] In this embodiment, by providing the mounting part 13 and the locking part 14 on the base 10, the quick disassembly and quick connection of the second bracket 12 and the first bracket 11 can be realized, which can improve the convenience of use of the rotary grill 100. And, in this embodiment, when the second bracket 12 is installed on the first bracket 11, the locking part 14 locks the second bracket 12, which can improve the connection stability between the second bracket 12 and the first bracket 11, thereby improving the structural stability of the rotary grill 100. At the same time, in this embodiment, by providing the pressing column 144 on the locking part 14, a single pressing action can unlock the locking part 14 and the second bracket 12, which can improve the disassembly efficiency of the second bracket 12, that is, realize the instantaneous decomposition of the base 10, thereby further facilitating the subsequent carrying and storage work of the user.
[0078] Please refer to Figure 7 , Figure 7 which Figure 2 is a schematic structural diagram of the rotating assembly 20 in the rotary grill 100 shown.
[0079] The rotating assembly 20 includes a connecting bushing 21 and a rotating member 22. The rotating member 22 includes a rotating shaft 23 and a rotating basket 24. The rotating shaft 23 is installed in the connecting bushing 21, and the rotating basket 24 is installed on the rotating shaft 23 and fixedly connected to the rotating shaft 23. The rotating assembly 20 is arranged between the first bracket 11 and the second bracket 12, and the connecting bushing 21 is fixedly connected to the output shaft 55 in the driving assembly 101. When the output shaft 55 rotates, it drives the connecting bushing 21 to rotate, so as to drive the rotating shaft 23 to rotate, and thus drive the rotating basket 24 to rotate.
[0080] Please refer to Figure 8 and Figure 9 , Figure 8 is Figure 7 a schematic structural view of the connecting bushing 21 in the rotating assembly 20 shown in Figure 9 is Figure 8 a schematic cross-sectional structural view of the connecting bushing 21 along the A-A direction shown in
[0081] The connecting bushing 21 includes a first connecting section 211 and a second connecting section 212. The first connecting section 211 and the second connecting section 212 are arranged along the axial direction of the connecting bushing 21. In this embodiment, the connecting bushing 21 is an integrally formed part. In other embodiments, the second connecting section 212 and the first connecting section 211 can also be fixedly connected by welding, screwing, etc. Among them, the second connecting section 212 is provided with a second connecting cavity 214. The second connecting cavity 214 penetrates through one end of the second connecting section 212 facing away from the first connecting section 211. The second connecting cavity 214 is cylindrical. That is, along the cross-section perpendicular to the axial direction of the connecting bushing 21, the inner wall of the second connecting cavity 214 is circular. The first connecting section 211 is provided with a first connecting cavity 213. The first connecting cavity 213 penetrates through one end of the first connecting section 211 facing away from the second connecting section 212, and the first connecting cavity 213 communicates with the second connecting cavity 214. Along the direction perpendicular to the axial direction of the connecting bushing 21, the profile of the cross-section of the first connecting cavity 213 is polygonal. That is, the inner wall of the first connecting cavity 213 is formed by connecting multiple planes end to end. And, the first connecting cavity 213 is trumpet-shaped, and along the direction away from the second connecting section 212, the area of the cross-section of the first connecting cavity 213 perpendicular to the axial direction of the connecting bushing 21 gradually increases. In this embodiment, along the direction perpendicular to the axial direction of the connecting bushing 21, the profile of the cross-section of the first connecting cavity 213 is hexagonal. In other embodiments, along the direction perpendicular to the axial direction of the connecting bushing 21, the profile of the cross-section of the first connecting cavity 213 can also be quadrilateral, pentagonal or octagonal, etc.
[0082] Please refer to Figure 10 , Figure 10 is Figure 7 a partial schematic structural view of the rotating shaft 23 in the rotating assembly 20 shown in
[0083] The rotating shaft 23 includes a first rotating section 231, a second rotating section 232, and a third rotating section 233. The second rotating section 232, the first rotating section 231, and the third rotating section 233 are sequentially connected along the axial direction of the rotating shaft 23. Among them, the second rotating section 232 is cylindrical, and the diameter of the second rotating section 232 is smaller than the diameter of the inscribed circle of the first connecting cavity 213. The first rotating section 231 is prismatic, the outer contour of the first rotating section 231 is consistent with the contour of the first connecting cavity 213, and each surface of the head of the first rotating section 231 has a slope to fit the contour of the first connecting cavity 213. Moreover, the size of the outer contour of the first rotating section 231 is equal to or slightly smaller than the size of the contour of the first connecting cavity 213 to ensure that the first rotating section 231 can be installed in the connecting bushing 21. That is, the area of the minimum cross-section of the first rotating section 231 perpendicular to its axial direction is less than or equal to the area of the minimum cross-section of the first connecting cavity 213 perpendicular to the axial direction of the connecting bushing 21. In this embodiment, the first rotating section 231 is a hexagonal prism. That is, the cross-section of the first rotating section 231 perpendicular to its axial direction is a hexagon. In other embodiments, the cross-section of the first rotating section 231 perpendicular to its axial direction may also be a quadrilateral, a pentagon, an octagon, etc.
[0084] The third rotating section 233 is connected to one end of the first rotating section 231 facing away from the second rotating section 232. In this embodiment, the third rotating section 233 is cylindrical. The outer surface of the third rotating section 233 is provided with a first limiting groove 2331 and a second limiting groove 2332. Both the first limiting groove 2331 and the second limiting groove 2332 are arranged circumferentially around the third rotating section 233, and the first limiting groove 2331 and the second limiting groove 2332 are arranged at intervals along the axial direction of the rotating shaft 23. The structures of both the first limiting groove 2331 and the second limiting groove 2332 match the structure of the notch of the accommodating groove 124 of the second bracket 12.
[0085] In this embodiment, the rotating shaft 23 further includes an extension section 234. The extension section 234 is connected to one end of the third rotating section 233 facing away from the first rotating section 231. The extension section 234 is provided with an annular groove 2341. The annular groove 2341 is arranged circumferentially around the extension section 234.
[0086] As Figure 7 shown, the rotating basket 24 is fixedly connected to the first rotating section 231, and the rotating basket 24 is used for placing food to be baked. In this embodiment, the rotating basket 24 includes a first fixing plate 241, a second fixing plate 242, and a plurality of roasting skewers 243. The first fixing plate 241 and the second fixing plate 242 are arranged at intervals along the axial direction of the rotating shaft 23. In this embodiment, both the first fixing plate 241 and the second fixing plate 242 are discs, and both the first fixing plate 241 and the second fixing plate 242 are provided with clamping grooves and insertion holes for clamping the roasting skewers 243.
[0087] One end of the roasting stick 243 is clamped to the first fixed plate 241, and the other end is inserted into the jack of the second fixed plate 242. That is, the roasting stick 243 is mounted between the first fixed plate 241 and the second fixed plate 242. A plurality of roasting sticks 243 are arranged at intervals around the circumferences of the first fixed plate 241 and the second fixed plate 242. The roasting stick 243 is used to skewer the food to be roasted. In this embodiment, the roasting stick 243 is detachably mounted on the first fixed plate 241 and the second fixed plate 242. When roasting food, the food to be roasted can be strung on the roasting stick 243, and then the roasting stick 243 is clamped to the first fixed plate 241 and the second fixed plate 242. After the food is roasted, the roasting stick 243 with the food can be detached from the first fixed plate 241 and the second fixed plate 242 for convenient hand-held consumption.
[0088] In one embodiment, as Figure 11 shown, the rotating assembly 20 can be a rotating cage 24a. The rotating cage 24a includes a main body 241a and a flip cover 242a. In this embodiment, the main body 241a is generally cylindrical. In other embodiments, the shape of the main body 241a can also be a prism or other shapes. The main body 241a is provided with a baking cavity. The baking cavity is used to place the food to be roasted. In this embodiment, the main body 241a is formed by a metal mesh. The main body 241a is provided with an opening, and the opening communicates with the baking cavity. The flip cover 242a is rotatably connected to the main body 241a. When the flip cover 242a is closed relative to the main body 241a, the flip cover 242a covers the opening, and the baking cavity is in a closed state, which can prevent the food to be roasted in the baking cavity from falling out of the rotating cage 24a. When the flip cover 242a is opened relative to the main body 241a, the opening is exposed, and the baking cavity is in an open state, and the user can put the food to be roasted into the baking cavity or take out the roasted food through the opening.
[0089] It should be noted that the user can select different rotating assemblies 20 according to the types of the food to be roasted. For example, when the food to be roasted is beef, mutton, etc., the Figure 7 shown rotating basket 24 can be used for roasting. At this time, the food to be roasted can be strung on the roasting stick 243 of the rotating basket 24 for roasting. When the food to be roasted is peanuts, chestnuts, melon seeds, etc., the Figure 11 shown rotating cage 24a can be used for roasting. At this time, the food to be roasted can be placed in the baking cavity for roasting.
[0090] Please refer to Figure 10 , Figure 12 and Figure 13 , Figure 12 is Figure 2 a partial cross-sectional structural schematic diagram of the rotating grill 100 shown, Figure 13 is Figure 12 a partial cross-sectional structural schematic diagram of the rotating grill 100 in another state.
[0091] In the figure, the rotating assembly 20 is installed on the base 10 and can rotate relative to the base 10 about the rotation axis 23. Among them, the second connecting section 212 of the connecting sleeve 21 is fixedly connected to the output shaft 55 of the driving assembly 101. Specifically, one end of the output shaft 55 penetrates into the second connecting cavity 214, that is, the second connecting section 212 is sleeved on the output shaft 55 and fixed by a pin. When the output shaft 55 rotates, it drives the connecting sleeve 21 to rotate synchronously. The second rotating section 232 of the rotation axis 23 is inserted into the connecting sleeve 21, and the third rotating section 233 of the rotation axis 23 is arranged in the accommodating groove 124 of the second bracket 12. The extension section 234 extends out of the outside of the second bracket 12. When taking out or placing the rotating basket 24, the pick-up handle locking groove 2341 can be used to realize the movement of the rotating basket 24. In this way, it is convenient to place and take out the rotating basket 24.
[0092] The rotating assembly 20 has two installation states. In the first installation state, the connecting sleeve 21 locks the rotation axis 23. When the connecting sleeve 21 rotates, it drives the rotation axis 23 to rotate, thereby driving the rotating basket 24 to rotate.
[0093] In the second installation state, on the contrary, the connecting sleeve 21 disconnects the torque transmission with the rotation axis 23 and the transmission is not linked. When the connecting sleeve 21 rotates, the inner wall of the connecting sleeve 21 rotates along the outer peripheral surface of the rotation axis 23. That is, when the connecting sleeve 21 rotates, it will not drive the rotation axis 23 and the rotating basket 24 to rotate. Correspondingly, when the rotation axis 23 and the rotating basket 24 rotate, they will not drive the connecting sleeve 21 to rotate and will not be hindered by the connecting sleeve 21. See Figure 13 , in this state, only a small hand force is required to rotate the rotating basket 24, which is convenient for cooperating with loading skewers before baking and taking out skewers after baking.
[0094] Continuing from the above text, as Figure 12 shown, in the first installation state of the rotating assembly 20, the second rotating section 232 is located in the second connecting cavity 214, and one end of the first rotating section 231 facing away from the third rotating section 233 is located in the first connecting cavity 213, and the outer wall of the first rotating section 231 is parallel or substantially parallel to the inner wall of the first connecting cavity 213. At the same time, the third rotating section 233 is arranged on the supporting part 123 of the second bracket 12. Specifically, the first limiting groove 2331 is correspondingly arranged with the accommodating groove 124 of the supporting part 123, and the bottom wall of the accommodating groove 124 is clamped in the first limiting groove 2331. See Figure 12The lower right figure. When the output shaft 55 rotates to drive the connection sleeve 21 to rotate, the connection sleeve 21 drives the first connection segment 211 to rotate synchronously, thereby driving the rotating shaft 23 and the rotating basket 24 to rotate. In this embodiment, by providing a first limiting groove 2331 on the rotating shaft 23, a limiting effect can be exerted on the rotating shaft 23 in the axial direction of the rotating shaft 23, which can prevent the rotating shaft 23 from moving along its axial direction, causing the first rotating segment 231 to disengage from the first connection cavity 213 and affecting the rotation of the rotating shaft 23 following the connection sleeve 21. Moreover, by providing a receiving groove 124 in the second bracket 12, a limiting effect can be exerted on the rotating shaft 23 in the Y-axis direction, which can prevent the rotating shaft 23 from rolling in the Y-axis direction. In this way, the connection stability between the rotating shaft 23 and the base 10 can be improved, and the rotation stability of the rotating shaft 23 and the rotating basket 24 can also be improved.
[0095] As Figure 13 shown, in the second installation state of the rotating assembly 20, the second rotating segment 232 is located in the first connection cavity 213 and the second connection cavity 214, and the first rotating segment 231 is completely located outside the connection sleeve 21. At the same time, the third rotating segment 233 is mounted on the supporting portion 123 of the second bracket 12. Specifically, the second limiting groove 2332 is correspondingly provided with the receiving groove 124 of the supporting portion 123, and the bottom wall of the receiving groove 124 is clamped in the second limiting groove 2332. When the output shaft 55 rotates to drive the connection sleeve 21 to rotate, the inner walls of the first connection cavity 213 and the second connection cavity 214 rotate along the outer peripheral surface of the second rotating segment 232. At this time, neither the rotating shaft 23 nor the rotating basket 24 rotates. In this embodiment, by providing the second limiting groove 2332 on the rotating shaft 23, a limiting effect can be exerted on the rotating shaft 23 in the axial direction of the rotating shaft 23, which can prevent the rotating shaft 23 from moving along its axial direction, causing the second rotating segment 232 to shift within the connection sleeve 21 and affecting the free rotation of the rotating shaft 23.
[0096] In this embodiment, by providing a cylindrical second connection segment 212 and a prismatic first rotating segment 231 on the rotating shaft 23, and providing a second connection segment 212 and a first connection segment 211 on the connection sleeve 21, when the first rotating segment 231 is located within the first connection segment 211, the connection sleeve 21 locks the rotating shaft 23. When the second rotating segment 232 straddles the first connection segment 211 and the second connection segment 212, the connection sleeve 21 and the rotating shaft 23 are unlocked, so that the user can conveniently adjust the state of the rotating basket 24 according to the usage situation. For example, when it is necessary for the rotating basket 24 to rotate following the connection sleeve 21, the rotating shaft 23 can be moved towards the direction close to the connection sleeve 21, so that one end of the first rotating segment 231 is locked in the first connection cavity 213 to achieve linkage, that is, the rotating assembly 20 is in Figure 12The first installation state shown; when the rotary basket 24 needs to be free, the rotary shaft 23 can be moved in a direction away from the connecting bushing 21, so that the first rotating section 231 disengages from the first connecting cavity 213 and unlocks from the connecting bushing 21, without linkage. That is, the rotary assembly 20 is in Figure 13 the second installation state shown to achieve gear shifting.
[0097] Please refer to Figure 14 and Figure 15 , Figure 14 which Figure 2 is a partial structural schematic diagram of the rotary grill 100 shown, Figure 15 and Figure 14 is a partial cross-sectional structural schematic diagram of the rotary grill 100 along the B-B direction shown.
[0098] The driving assembly 101 includes a driving member 30, a transmission member 40, and a speed-changing member 50. The driving member 30 includes a fluid chamber 31, a connecting pipe 32, and a hydraulic cylinder 33. The fluid chamber 31, the connecting pipe 32, and the hydraulic cylinder 33 are connected in sequence and communicate with each other. Among them, the hydraulic cylinder 33 includes a cylinder barrel 331, a cylinder head 332, a piston 333, a piston rod 334, and a spring 335. In this embodiment, the cylinder barrel 331 is a cylinder. The inside of the cylinder barrel 331 is a hydraulic chamber 337. The cylinder head 332 is provided at one end of the cylinder barrel 331 axially away from the connecting pipe 32.
[0099] The piston 333 is provided inside the hydraulic cylinder 33 and is hermetically connected to the inner wall of the hydraulic cylinder 33. Exemplarily, a sealing ring 336 is provided on the outer periphery of the piston 333. One end of the piston rod 334 is fixedly connected to the piston 333. The other end of the piston rod 334 passes through the cylinder head 332 and extends outside the cylinder barrel 331. The spring 335 is provided in the hydraulic chamber 337 and is located between the piston 333 and the cylinder head 332, and the spring 335 is coaxially arranged with the cylinder barrel 331. Specifically, the spring 335 is sleeved on the outer periphery of the piston rod 334, and one end of the spring 335 abuts against the piston 333, and the other end abuts against the cylinder head 332.
[0100] The fluid chamber 31 is provided with a storage chamber 311, and the fluid chamber 31 is used for storing fluid. In this embodiment, the fluid includes hydraulic oil and gas. That is, the fluid is a mixture of hydraulic oil and gas. Exemplarily, the hydraulic oil can be mineral oil, such as chain oil, etc.; the gas is air, or the gas can also be other inert gases. The connecting pipe 32 is connected between the fluid chamber 31 and the hydraulic cylinder 33, and the connecting pipe 32 communicates with both the fluid chamber 31 and the hydraulic cylinder 33. The connecting pipe 32 is provided with a feeding port 321. The storage chamber 311 and the cavity of the connecting pipe 32 together form a machine cavity. The fluid is added into the machine cavity through the feeding port 321.
[0101] When the ambient temperature around the fluid chamber 31 rises, thermal energy is transferred into the fluid chamber 31. The fluid inside the fluid chamber 31 will expand when heated. Among them, the gas has a small specific heat capacity and a large coefficient of thermal expansion, so it will react quickly and its volume will expand first, exerting pressure on the hydraulic oil below. The hydraulic oil is pressurized and enters the connecting pipe 32, and then enters the hydraulic chamber 337 of the hydraulic cylinder 33 through the connecting pipe 32, thereby pushing the piston 333 to move towards the cylinder head 332 to drive the piston rod 334 to do work. Further, when the temperature continues to rise, both the hydraulic oil and the gas in the fluid chamber 31 expand when heated, causing more hydraulic oil to enter the hydraulic chamber 337, so that the piston 333 is subjected to more pressure, thereby further pushing the piston 333 and the piston rod 334 to move forward.
[0102] As Figure 14 and Figure 16 shown, the driving member 30 further includes a heat insulation sleeve 34. The heat insulation sleeve 34 is sleeved on the outer periphery of the cylinder barrel 331 to protect the cylinder barrel 331 to avoid the influence of the external high-temperature environment on the hydraulic cylinder 33 and cause deformation.
[0103] Furthermore, the driving member 30 is installed on the first bracket 11. Among them, the hydraulic cylinder 33 and part of the connecting pipe 32 are located in the receiving cavity 114. As shown in the figure, an ear plate 35 is provided on one side of the connecting pipe 32, and an ear plate hole 351 is provided on the ear plate 35. The pin shaft 352 passes through the ear plate hole 351, passes through the second side plate 112 and the first side plate 111, and is rotatably connected to the first bracket 11 near the bottom plate 113. In other embodiments, the driving assembly 101 can also be fixedly connected to the first bracket 11 by bolts or buckles, etc.
[0104] Please continue to refer to Figure 14 and Figure 15 , the transmission member 40 includes a rack 41 and a transmission gear 42. The rack 41 includes a first end 411 and a second end 412. The first end 411 and the second end 412 are oppositely arranged along the length direction of the rack 41. A first tooth 413 is provided on the side surface of the rack 41. The teeth of the first tooth 413 are arranged along the length direction of the rack 41 and extend from the first end 411 to the second end 412. The rack 41 is fixedly connected to the piston rod 334 of the hydraulic cylinder 33, and the length direction of the rack 41 is parallel or substantially parallel to the axial direction of the piston rod 334. When the piston rod 334 moves along its axial direction, it can drive the rack 41 to move along its length direction.
[0105] The transmission gear 42 includes a second set of teeth 421. The teeth of the second set of teeth 421 are arranged around the outer circumference of the transmission gear 42. The transmission gear 42 is located in the receiving cavity 114 and is used for rotatably connecting with the speed-changing member 50. The transmission gear 42 meshes with the rack 41. Specifically, the second set of teeth 421 of the transmission gear 42 meshes with the first set of teeth 413 of the rack 41. Thus, when heat energy causes the hydraulic oil to enter the hydraulic cylinder 33 and drives the rack 41 to move through the piston rod 334, the rack 41 drives the transmission gear 42 to rotate, thereby driving the speed-changing member 50 to rotate, and further driving the rotating assembly 20 to rotate.
[0106] As Figure 14 and Figure 15 shown, in this embodiment, the rotary grill 100 further includes a guide wheel 43. The guide wheel 43 is installed in the fixed frame 44 and is rotatably connected to the fixed frame 44. The guide wheel 43 is located on the side of the rack 41 facing away from the first set of teeth 413 and is in contact with the surface of the rack 41. It can be understood that the rack 41 is located between the guide wheel 43 and the transmission gear 42. When the rack 41 moves along its length direction, the corresponding outer surface of the rack 41 rolls along the outer circumferential surface of the guide wheel 43. The guide wheel 43 plays a limiting role on the rack 41, which can prevent the rack 41 from disengaging from the transmission gear 42 due to the reaction force. In this way, the meshing stability between the rack 41 and the transmission gear 42 can be improved, and thus the rotational stability of the transmission gear 42 and the input shaft 54 can be improved, that is, the transmission effect of the transmission member 40 can be improved.
[0107] In this embodiment, the guide wheel 43 is rotatably connected to the fixed frame 44. When the rack 41 moves along its length direction, the contact between the rack 41 and the guide wheel 43 is a rolling friction, and at the same time, the rack 41 drives the guide wheel 43 to rotate around its axis. In this way, the friction between the rack 41 and the guide wheel 43 can be reduced. In other embodiments, the guide wheel 43 can also be fixedly connected to the fixed frame 44.
[0108] Please refer to Figure 16 and Figure 17 , Figure 16 which Figure 2 is a partial structural schematic diagram of the rotary grill 100 shown, Figure 17 and Figure 16 is a partial structural schematic diagram of the speed-changing member 50 in the rotary grill 100.
[0109] The speed-changing member 50 includes a chassis 51 (as Figure 2 shown), a first gear 52, a second gear 53, an input shaft 54, an output shaft 55, and a speed-changing gear set 56. The housing is provided on the side of the second side plate 112 facing away from the receiving cavity 114 and is fixedly connected to the second side plate 112. The first gear 52, the second gear 53, and the speed-changing gear set 56 are all located inside the chassis 51.
[0110] As shown in Figure 2 , Figure 15 and Figure 16 , the rotary grill 100 further includes a fixed frame 44 located within the receiving cavity 114. The top plate of the fixed frame 44 is fixedly connected to the first side plate 111, and the bottom plate of the fixed frame 44 is fixedly connected to the second side plate 112. The input shaft 54 vertically penetrates through the second side plate 112 and the bottom plate of the fixed frame 44, and is connected to the laminate and top plate of the fixed frame 44 through rolling bearings, and is perpendicular and non-intersecting with the rack 41. Specifically, one end of the input shaft 54 penetrates through the second side plate 112 and extends into the receiving cavity 114 and is fixedly connected to the transmission gear 42 within the fixed frame 44, and the laminate and top plate of the fixed frame 44 are both provided with first rolling bearings 571 to intersect and connect with the input shaft 54. The other end of the input shaft 54 penetrates into the chassis 51 and is connected to the first gear 52 through the first one-way bearing 1. Figure 2 In
[0111] , the chassis 51 of the speed-changing member 50 is provided with a second rolling bearing 572 to intersect and connect with the input shaft 54.
[0112] Please refer to Figure 2 , Figure 16 and Figure 17 , the first gear 52 is mounted on the input shaft 54 through the first one-way bearing 1. Among them, the number of teeth of the first gear 52 is more than that of the transmission gear 42 and the diameter of the first gear 52 is greater than that of the transmission gear 42. The output shaft 55 intersects and connects with the first side plate 111 through the third rolling bearing 573. In addition, the output shaft 55 intersects and connects with the chassis 51 through the fourth rolling bearing 574. The axial direction of the output shaft 55 is parallel to the X-axis direction, and the output shaft 55 is parallel to the input shaft 54 and is spaced apart. The output shaft 55 is used to connect to the rotating assembly 20. Specifically, as shown in Figure 12 , the output shaft 55 is fixedly connected to the connecting bushing 21 in the rotating assembly 20. Exemplarily, the output shaft 55 and the connecting bushing 21 can be fixedly connected by pins or screws, etc. When the output shaft 55 rotates, it can drive the connecting bushing 21 to rotate, thereby driving the rotating shaft 23 and the rotating basket 24 to rotate. That is, when the output shaft 55 rotates, it can drive the rotating assembly 20 to rotate through the connecting bushing 21.
[0113] The second gear 53 is mounted on the output shaft 55 and fixedly connected to the output shaft 55. The speed-changing gear set 56 is mounted in the box body and meshes with the first gear 52 and the second gear 53 respectively. When the input shaft 54 rotates, it can drive the first gear 52 to rotate. The first gear 52 drives the second gear 53 to rotate through the speed-changing gear set 56, thereby driving the output shaft 55 to rotate, and further driving the rotating assembly 20 to rotate. Therefore, relatively speaking, the first gear 52 is the driving gear and the second gear 53 is the driven gear. Among them, the transmission ratio of the first gear 52 to the second gear 53 is less than 1. That is to say, the rotational speed of the second gear 53 is greater than that of the first gear 52.
[0114] Specifically, the speed-changing gear set 56 includes a plurality of double-connected intermediate gears. In this embodiment, the speed-changing gear set 56 is composed of the double-connected intermediate gear A 561 and the double-connected intermediate gear B 562. Exemplarily, the speed-changing gear set 56 includes N double-connected intermediate gears. N is a positive integer greater than or equal to 1. That is, the double-connected intermediate gears are the double-connected intermediate gear A 561, the double-connected intermediate gear B 562, the double-connected intermediate gear C... arranged in sequence until the Nth double-connected intermediate gear. Each double-connected intermediate gear includes a large gear and a small gear coaxially arranged. In this embodiment, the double-connected intermediate gear A 561 is the driven gear of the first gear 52. In order to amplify the speed of the first gear 52, the double-connected intermediate gear A 561 uses its own small gear as the rotation input to mesh with the first gear 52 to obtain a higher rotational speed than the first gear 52. And so on, the double-connected intermediate gear B 562 is the driven gear of the double-connected intermediate gear A 561. The double-connected intermediate gear B 562 uses its own small gear as the rotation input to mesh with the large gear of the double-connected intermediate gear A 561, and then transmits the rotation from its own large gear, thereby realizing the progressive increase of the rotational speed.
[0115] It should be noted that in the actual design process, the number of double-connected intermediate gears and the same module number of teeth of the gears can be changed according to requirements to change the rotational speed of the second gear 53.
[0116] Please refer to Figure 15 、 Figures 18 to 20 , Figure 18 is Figure 2 a partial structural schematic diagram of the rotary grill 100 in the first state, Figure 19 is Figure 2 a partial structural schematic diagram of the rotary grill 100 in the second state, Figure 20 is Figure 2 a partial sectional structural schematic diagram of the rotary grill 100 in the second state.
[0117] As Figure 15 and Figure 18As shown, in the first state, the piston 333 in the hydraulic cylinder 33 is located on the side close to the connecting pipe 32, the spring 335 is in a pre-compressed state, and the first tooth 413 of the rack 41 near the first end 411 meshes with the transmission gear 42. At this time, the ambient temperature around the rotary grill 100 is relatively low, and the fluid in the fluid chamber 31 does not expand or has a low degree of expansion. Exemplarily, when the rotary grill 100 is not placed in the cooking device 110, or when the cooking device 110 has not started heating, or when the cooking device 110 has just started heating but the temperature is low, the rotary grill 100 is in the first state. Among them, "the spring 335 is in a pre-compressed state" means that the spring 335 is in a state where it can continue to be compressed. Specifically, the spring 335 can be in a natural state or in a compressed state but with a small compression amount.
[0118] When the rotary grill 100 is in the first state and the ambient temperature around the rotary grill 100 continues to rise, the fluid in the fluid chamber 31 expands due to heat and enters the hydraulic chamber 337 of the hydraulic cylinder 33 through the connecting pipe 32, thereby pushing the piston 333 towards the cylinder head 332, driving the piston rod 334 to move away from the cylinder barrel 331, and compressing the spring 335. When the piston rod 334 moves away from the cylinder barrel 331, it drives the rack 41 to move away from the hydraulic cylinder 33, so that the first tooth 413 drives the second tooth 421 through meshing, thereby driving the transmission gear 42 to rotate in the positive direction. When the transmission gear 42 rotates in the positive direction, it drives the input shaft 54 to rotate in the positive direction, driving the first gear 52 to rotate in the positive direction. When the first gear 52 rotates in the positive direction, it drives the speed change gear set 56 to rotate, thereby driving the second gear 53 to rotate, and further driving the output shaft 55 to rotate. When the output shaft 55 rotates, it drives the connecting bushing 21 to rotate, thereby driving the rotating shaft 23 to rotate, and further driving the rotating basket 24 to rotate, and causing the food provided on the rotating basket 24 to rotate, so that the rotary grill 100 enters the second state.
[0119] As Figure 19 and Figure 20 As shown, when the rotary grill 100 is in the second state, the distance between the piston 333 in the hydraulic cylinder 33 and the end of the cylinder barrel 331 close to the connecting pipe 32 expands, the spring 335 is in a fully compressed state, and the first tooth 413 of the rack 41 near the second end 412 meshes with the transmission gear 42. At this time, the ambient temperature around the rotary grill 100 is relatively high, the fluid in the fluid chamber 31 expands to a high level, and part of it is located in the hydraulic chamber 337. Exemplarily, when the rotary grill 100 is placed in the cooking device 110 and the cooking device 110 is heated to a high temperature, the rotary grill 100 is in the second state.
[0120] In this embodiment, by providing a fluid chamber 31 filled with fluid in the rotary grill 100, when the fluid chamber 31 is heated, the expansion force of the fluid can drive the rotary basket 24 to rotate. That is to say, the rotary grill 100 can utilize the heat generated by the cooking device 110 for cooking food to achieve rotation, without the need to additionally provide a driving device such as a motor. This can simplify the structure of the rotary grill 100, save energy, improve the reliability of the rotary grill 100, and extend the service life of the rotary grill 100.
[0121] Moreover, in this embodiment, by providing a hydraulic cylinder 33, the pressure generated by the expansion of the fluid in the fluid chamber 31 drives the piston 333 and the piston rod 334 in the hydraulic cylinder 33 to move. Then, the above movement is converted into rotation by the transmission member 40, and the speed is increased by the speed-changing member 50 to drive the rotary basket 24 to rotate, thereby improving the working efficiency of the driving assembly 101.
[0122] Meanwhile, in this embodiment, by providing a rack 41 and a transmission gear 42 and meshing the rack 41 with the transmission gear 42, the linear movement of the piston rod 334 can be converted into the rotation of the transmission gear 42, thereby realizing the rotation of the input shaft 54 and further realizing the rotation of the rotary basket 24, which can simplify the structure of the rotary grill 100 and save manufacturing costs.
[0123] It should be noted that as the ambient temperature around the rotary grill 100 increases, the fluid in the fluid chamber 31 gradually expands, and gradually drives the piston rod 334 in the hydraulic cylinder 33 to drive the rack 41 to move, thereby driving the transmission gear 42 to rotate, and further driving the rotary basket 24 to rotate. Exemplarily, the time required for the piston 333 to complete one stroke is 10 to 30 minutes. That is to say, the time required for the rack 41 to move from the first end 411 meshed with the transmission gear 42 to the second end 412 meshed with the transmission gear 42 is 10 to 30 minutes. That is, the time required for the rotary grill 100 to transform from the first state to the second state is 10 to 30 minutes. In this way, the rotation duration of the rotary grill 100 can be increased, so that the food rotates during the actual baking process, avoiding the long-term output of heat energy to the same part of the food.
[0124] It can be understood that the overall expansion speed of the fluid in the fluid chamber 31 is relatively slow, and the speed at which the hydraulic cylinder 33 drives the rack 41 and the transmission gear 42 is relatively slow. In this embodiment, by providing a speed-changing member 50 and arranging a speed-changing gear set 56 between the first gear 52 and the second gear 53 of the speed-changing member 50, the rotation speed of the second gear 53 is greater than that of the first gear 52, which can increase the rotation speed of the second gear 53 and the output shaft 55, thereby increasing the rotation speed of the rotating shaft 23 and the rotary basket 24, and further improving the uniformity of food baking.
[0125] In this embodiment, the fluid in the fluid chamber 31 is a gas-liquid mixture. When the ambient temperature around the fluid chamber 31 rises and heat energy penetrates into the storage chamber 311, the gas in the fluid chamber 31 expands first when heated and squeezes the hydraulic oil in the same chamber into the hydraulic chamber 337, and finally drives the rotary basket 24 to rotate through the hydraulic cylinder 33; when the temperature further rises, both the hydraulic oil and the gas in the fluid chamber 31 expand significantly when heated, and more hydraulic oil enters the hydraulic chamber 337, causing the hydraulic cylinder 33 to be continuously pressurized, and the hydraulic oil further drives the rotary basket 24 to rotate through the hydraulic cylinder 33. In this embodiment, by adding a gas-liquid mixture fluid to the fluid chamber 31, the action response time of the driving member 30 can be advanced.
[0126] Please continue to refer to Figure 18 and Figure 19 , after the rotary grill 100 in the second state, when the ambient temperature around it decreases, for example, when the cooking device 110 stops heating or the rotary grill 100 is taken out of the cooking device 110, the fluid contracts when cooled, the pressure of the fluid on the piston 333 decreases, and the piston 333 moves towards the bottom of the hydraulic cylinder 33 under the elastic force of the spring 335, so as to drive the piston rod 334 to move away from the transmission gear 42, thereby driving the rack 41 to move along the direction from the second end 412 to the first end 411, and driving the transmission gear 42 and the input shaft 54 to rotate in the reverse direction, and then making the rotary grill 100 return to Figure 18 the first state shown in
[0127] Please refer to in combination with Figure 16 , Figure 17 and Figure 21 , Figure 21 is Figure 16 the partial exploded structural schematic diagram of the rotary grill 100 shown in
[0128] In this embodiment, the drive assembly 101 further includes a first one-way bearing 1. Among them, a one-way bearing is a bearing that can rotate freely in one direction and is locked in the other direction, which has the same function as a ratchet mechanism, that is, the upper-level mechanism can transmit the rotation in one direction to the lower-level mechanism, while the lower-level mechanism cannot transmit the rotation in the same direction to the upper-level mechanism, and the reverse rotation of the upper-level mechanism will not be transmitted to the lower-level mechanism. In this embodiment, the one-way bearing is a roller one-way bearing. In another embodiment, other types of one-way bearings or ratchet mechanisms can be used.
[0129] Please refer to in combination with Figure 18 and Figure 19When the rotary grill 100 is switched from the first state to the second state, the hydraulic cylinder 33 drives the rack 41 to move, driving the transmission gear 42 and the input shaft 54 to rotate in the forward direction, thereby driving the first one-way bearing 1 to rotate in the forward direction. Further, the first one-way bearing 1 drives the first gear 52 to rotate in the forward direction, and the first gear 52 drives the speed change gear set 56 to rotate, so as to drive the second gear 53, the output shaft 55 and the rotary basket 24 to rotate.
[0130] When the rotary grill 100 is switched from the second state to the first state, the hydraulic cylinder 33 drives the rack 41 to retract, so as to drive the transmission gear 42 and the input shaft 54 to rotate in the reverse direction, and the input shaft 54 rotates relative to the first one-way bearing 1. At this time, when the input shaft 54 rotates, it cannot drive the first one-way bearing 1 to rotate, so it cannot drive the first gear 52, the speed change gear set 56, the second gear 53 and the rotary basket 24 to rotate either.
[0131] It can be understood that in this embodiment, by arranging the first one-way bearing 1 between the input shaft 54 and the first gear 52, when the rotary grill 100 is switched from the first state to the second state, the input shaft 54 can drive the first one-way bearing 1 to rotate, while when the rotary grill 100 is switched from the second state to the first state, the input shaft 54 does not drive the first one-way bearing 1 to rotate. In this way, when the rotary grill 100 returns to the first state, the transmission between the input shaft 54 and the first gear 52 can be cut off, reducing the resistance of the rack 41 and the hydraulic cylinder 33 when returning to the first state, and improving the efficiency of the rotary grill 100 when returning to the first state.
[0132] Please refer to Figure 22 , Figure 22 is Figure 2 a partial structural schematic diagram of the rotary grill 100 shown in
[0133] The rotary grill 100 further includes an auxiliary driving assembly 60. The auxiliary driving assembly 60 is installed in the receiving cavity 114 and is connected to the output shaft 55. The auxiliary driving assembly 60 can drive the output shaft 55 to rotate, thereby driving the rotating assembly 20 to rotate. Among them, the auxiliary driving assembly 60 includes a mounting wheel 61, a pulling rope 62 and a thermal coupling member 63. The mounting wheel 61 is sleeved on the outer periphery of the output shaft 55, and the mounting wheel 61 can drive the output shaft 55 to rotate. The tail end of the pulling rope 62 is fixedly connected to the mounting wheel 61, and the head end is connected to the thermal coupling member 63. When the thermal coupling member 63 is deformed by heat, it drives the head end of the pulling rope 62 to move away from the output shaft 55. Driven by the head end of the pulling rope 62, the pulling rope 62 is tightened to drive the mounting wheel 61 to rotate, thus driving the output shaft 55 to rotate.
[0134] Please combine with Figure 23 , Figure 23 is Figure 22 a partial exploded structural schematic diagram of the rotary grill 100 shown in
[0135] The auxiliary drive assembly 60 further includes a baffle 64 and fixing posts 65. The baffle 64 is provided with a rope passing hole 641. The rope passing hole 641 penetrates through the baffle 64 along the thickness direction of the baffle 64, and the rope passing hole 641 is used for threading the pulling rope 62. One end of the fixing post 65 is fixedly connected to the baffle 64, and the other end is fixedly connected to the bottom plate 113 of the first bracket 11. In this embodiment, there are two fixing posts 65. The two fixing posts 65 are arranged at intervals along the Y-axis direction, and both fixing posts 65 are fixedly connected to the baffle 64 and the bottom plate 113. It can be understood that the baffle 64 and the bottom plate 113 are arranged at intervals along the Z-axis direction, and are fixedly connected through the fixing posts 65.
[0136] The thermal coupling member 63 includes a plurality of thermal coupling sheets 63a. The plurality of thermal coupling sheets 63a are stacked along the Z-axis direction. The thermal coupling sheet 63a is a wing-shaped thin sheet body. Each thermal coupling sheet 63a includes a fixing portion 631a and a deformation portion 632a. The fixing portion 631a is provided with a middle hole 6311a and two side holes 6312a. The deformation portion 632a is crescent-shaped, and the deformation portion 632a is fixedly connected to the fixing portion 631a in a manner of closing both ends. In this embodiment, each thermal coupling sheet 63a includes two deformation portions 632a. The two deformation portions 632a are respectively oppositely connected to opposite sides of the fixing portion 631a. In the initial state, the deformation portion 632a and the fixing portion 631a are substantially in the same plane. When the thermal coupling sheet 63a is heated, the deformation portion 632a will deform toward one side in the thickness direction of the thermal coupling sheet 63a. At this time, the deformation portion 632a bends relative to the fixing portion 631a. In this embodiment, when the thermal coupling sheet 63a is heated, the deformation directions of the two deformation portions 632a of the same thermal coupling sheet 63a are the same. The thermal coupling member 63 is arranged between the baffle 64 and the bottom plate 113. The fixing posts 65 string up all the thermal coupling sheets 63a through the two side holes 6312a, and the thermal coupling sheets 63a can move along the axial direction of the fixing posts 65. At this time, the fixing posts 65 play a guiding role in the movement of the thermal coupling sheets 63a.
[0137] In the auxiliary drive assembly 60, the mounting wheel 61 is provided with a mounting hole 615 and an annular groove 616. The mounting hole 615 penetrates through the mounting wheel 61 along the axial direction of the mounting wheel 61. The annular groove 616 is arranged on the outer peripheral surface of the mounting wheel 61 and surrounds the circumferential direction of the mounting wheel 61. The annular groove 616 is used for winding the pulling rope 62. The outer periphery of the mounting wheel 61 is further provided with a first fixing seat 611 and a second fixing seat 612. The first fixing seat 611 is provided with a second through hole 613. The second through hole 613 is used for the pulling rope 62 to penetrate. The second fixing seat 612 is provided with a third through hole 614. The third through hole 614 is used for the insertion and anchoring of one end of the return spring 66 of the auxiliary drive assembly 60.
[0138] The mounting wheel 61 is sleeved on the outer periphery of the output shaft 55. The tail end of the pulling rope 62 passes through the second through hole 613 and is fixedly connected to the first fixing seat 611. The pulling rope 62 extends along the annular groove 616 towards the baffle 64, and successively passes through the rope passing hole 641 of the baffle 64 and the middle hole 6311a of the thermal coupling member 63, and is fixedly connected to the bottom of the thermal coupling member 63. It can be understood that the head end of the pulling rope 62 is fixedly connected to the thermal coupling piece 63a closest to the bottom plate 113 among the plurality of thermal coupling pieces 63a.
[0139] Please refer to Figures 22 to 26 , Figure 24 which Figure 22 is a schematic structural diagram of the rotary grill 100 in another state as shown. Figure 25 which Figure 24 is a partial schematic structural diagram of the rotary grill 100 shown. Figure 26 which Figure 25 is a partial schematic structural diagram of the thermal coupling member 63 in the rotary grill 100 shown.
[0140] The auxiliary driving assembly 60 has a third state and a fourth state. As Figure 22 shown, when the auxiliary driving assembly 60 is in the third state, the deformed part 632a and the fixed part 631a of the thermal coupling piece 63a are substantially in the same plane, and the dimension of the thermal coupling member 63 in the Z-axis direction is L1. Exemplarily, when the rotary grill 100 is not placed in the cooking device 110, or the cooking device 110 has not started heating, or the cooking device 110 has just started heating but the temperature is low, the auxiliary driving assembly 60 is in the third state.
[0141] After the ambient temperature around the auxiliary driving assembly 60 begins to rise, the thermal coupling piece 63a is deformed by heat, and the distance between at least some adjacent thermal coupling pieces 63a increases. The bottom of the thermal coupling member 63 moves towards the bottom plate 113, that is, the thermal coupling piece 63a closest to the bottom plate 113 moves towards the bottom plate 113, thereby driving the head end of the pulling rope 62 to move towards the bottom plate 113. When the head end of the pulling rope 62 moves towards the bottom plate 113, the pulling rope 62 is tightened to unwind the mounting wheel 61 and drive the output shaft 55 to rotate in the positive direction. The output shaft 55 drives the connecting bushing 21 to rotate in the positive direction, thereby driving the rotating shaft 23 and the rotating basket 24 to rotate, and further enabling the auxiliary driving assembly 60 to be in Figure 24 the fourth state shown.
[0142] As Figures 24 to 26As shown, when the auxiliary drive assembly 60 is in the fourth state, the thermal coupling piece 63a is in a deformed state, and the deformed portion 632a is bent relative to the fixed portion 631a. The dimension of the thermal coupling piece 63 in the Z-axis direction is L2. Among them, L2 is greater than L1. Specifically, the thermal coupling piece 63 includes a plurality of thermal coupling pieces 63a, and every two thermal coupling pieces 63a form a group of thermal coupling piece groups 63b. Multiple groups of thermal coupling piece groups 63b are stacked in sequence in the Z-axis direction. When the auxiliary drive assembly 60 is transformed from the third state to the fourth state, the total four pairwise facing deformed portions 632a of the two thermal coupling pieces 63a in the same thermal coupling piece group 63b are deformed in a face-to-face direction. The space occupied by each group of thermal coupling piece groups 63b in the Z-axis direction increases, so that the thermal coupling piece 63 as a whole elongates toward the bottom plate 113 direction, and the dimension of the thermal coupling piece 63 in the Z-axis direction elongates from L1 to L2, increasing the dimension of the thermal coupling piece 63 in the Z-axis direction when the auxiliary drive assembly 60 is in the fourth state, thereby increasing the number of turns of the rotation basket 24 driven by the auxiliary drive assembly 60.
[0143] Among them, the thermal coupling piece 63 may include a plurality of thermal coupling pieces 63a with different thicknesses. The thermal coupling pieces 63a with different thicknesses will not deform simultaneously at the same temperature, enabling the thermal coupling piece 63 to extend the working time under the same thermal working conditions.
[0144] It should be noted that the thermal coupling piece 63 can deform at a relatively low ambient temperature. That is, the thermal coupling piece 63 is relatively sensitive. During actual use, as the temperature of the environment around the rotary grill 100 rises, the thermal coupling piece 63 first deforms and drives the rotation basket 24 to rotate through the auxiliary drive assembly 60; as the temperature further rises, the gas in the fluid chamber 31 expands due to heat and drives the rotation basket 24 to rotate through the hydraulic cylinder 33, the transmission member 40, and the speed change member 50; as the temperature rises further, both the gas and the hydraulic oil in the fluid chamber 31 expand due to heat and drive the rotation basket 24 to rotate through the hydraulic cylinder 33, the transmission member 40, and the speed change member 50. The setting of the auxiliary drive assembly 60 and the arrangement of the combination of the gas and the hydraulic oil are beneficial to make up for the lack of power in the early stage of the operation of the present application.
[0145] Please continue to refer to Figures 22 to 24 , the auxiliary drive assembly 60 further includes a resilient member 66. Among them, the resilient member 66 is an elastic structural member. In this embodiment, the resilient member 66 is a spiral structure formed by elastic wire. The resilient member 66 is located on the side of the mounting wheel 61 facing away from the second side plate 112 and is sleeved on the outer periphery of the output shaft 55. One end of the resilient member 66 passes through and is anchored in the third through hole 614 of the second fixing seat 612 and is fixedly connected to the mounting wheel 61. The other end of the resilient member 66 is fixedly connected to the first side plate 111. Exemplarily, the second side plate 112 is provided with a through hole, and the end of the resilient member 66 is hook-shaped. The end of the resilient member 66 passes through the through hole and is hooked on the first side plate 111.
[0146] When the auxiliary drive assembly 60 is in the third state, the resilient member 66 is in the initial tightened state. When the auxiliary drive assembly 60 switches from the third state to the fourth state, the mounting wheel 61 rotates and drives the resilient member 66 to wind, reaching the highly tightened state and accumulating elastic force. When the ambient temperature around the rotary grill 100 decreases, for example, when the cooking device 110 stops heating or the rotary grill 100 is taken out of the cooking device 110, the thermal coupling piece 63a returns from the deformed state to the initial state, and the acting force of the thermal coupling member 63 on the pull rope 62 decreases or even disappears. At this time, the resilient member 66 releases part of the elastic force to drive the mounting wheel 61 to rotate in the reverse direction, and winds the pull rope 62 through the rotation of the mounting wheel 61, so that the pull rope 62 remains taut, and the head end of the pull rope 62 moves in the direction away from the bottom plate 113, thereby driving the thermal coupling piece 63a to gather and fold, and making the auxiliary drive assembly 60 return to the third state as shown in Figure 22 shown.
[0147] In this embodiment, by arranging the resilient member 66 in the auxiliary drive assembly 60, when the thermal coupling piece 63a returns from the deformed state to the initial state, the resilient member 66 can balance the pulling forces at both ends of the pull rope 62, buffer the explosive force of the thermal coupling member 63, and store kinetic energy. The resilient member 66 winds and pulls the pull rope 62 through the mounting wheel 61, so that the auxiliary drive assembly 60 can return to the third state, enabling the auxiliary drive assembly 60 to continue to play a driving role in the next cycle.
[0148] As Figure 23 shown, in this embodiment, the auxiliary drive assembly 60 further includes a second one-way bearing 67. The second one-way bearing 67 has the same or similar structure as the first one-way bearing 1. The second one-way bearing 67 can rotate freely in one direction and be locked in the other direction. The second one-way bearing 67 is sleeved on the outer periphery of the output shaft 55 in the mounting hole 615 and is fixedly connected to the mounting wheel 61 through the outer ring.
[0149] When the auxiliary drive assembly 60 switches from the third state to the fourth state, the thermal coupling member 63 deforms, and drives the mounting wheel 61 to rotate in the forward direction through the pull rope 62. The mounting wheel 61 drives the second one-way bearing 67 to rotate in the forward direction, and the second one-way bearing 67 drives the output shaft 55 to rotate in the forward direction synchronously, thereby driving the connecting shaft sleeve 21, the rotating shaft 23, and the rotating basket 24 to rotate.
[0150] Correspondingly, when the thermal coupling member 63 returns from the deformed state to the natural state and relaxes the pull rope 62, and the resilient member 66 drives the mounting wheel 61 to rotate in the reverse direction, the mounting wheel 61 drives the second one-way bearing 67 to rotate in the reverse direction. At the same time, the second one-way bearing 67 rotates relative to the output shaft 55, that is, the second one-way bearing 67 does not drive the output shaft 55 to rotate.
[0151] In this embodiment, by providing a second one-way bearing 67 between the mounting wheel 61 and the output shaft 55, when the auxiliary drive assembly 60 switches from the third state to the fourth state, the mounting wheel 61 can drive the output shaft 55 to rotate through the second one-way bearing 67. When the auxiliary drive assembly 60 switches from the fourth state to the third state, the second one-way bearing 67 does not drive the output shaft 55 to rotate. In this way, when the rotation transmitted from the hydraulic chamber 337 to the transmission member 50 reaches the output shaft 55, the second one-way bearing 67 cuts off the rotational connection between the auxiliary drive assembly 60 and the output shaft 55. The auxiliary drive assembly 60 gives way to the transmission member 50. This diversifies the sources of the rotational force without mutual interference, making the rotary grill 100 operate smoothly.
[0152] In this embodiment, by providing an auxiliary drive assembly 60 on the rotary grill 100, at the initial stage when the cooking device 110 is turned on, when there is little heat energy accumulation and the pressure of the fluid is not sufficient to cause the drive assembly 101 to rotate the rotating basket 24, it is possible to make the rotating basket 24 move first, playing a role of relative cold start and adding an extra insurance against scorching.
[0153] Please refer to Figure 27 , Figure 27 which is a partial structural schematic diagram of the rotary grill 100 provided by another embodiment of the present application.
[0154] The rotary grill 100 shown in this embodiment is different from the rotary grill 100 provided by the embodiments shown in Figure 2 , Figure 14 in that the transmission member 40 includes a swing arm 45. The swing arm 45 includes a first end 451 and a second end 452. The first end 451 and the second end 452 are oppositely arranged along the length direction of the swing arm 45. The first end 451 is fixedly connected to the input shaft 54, and the second end 452 is rotatably connected to the piston rod 334.
[0155] Wherein, the swing arm 45 is provided with a first shaft hole 453 and a second shaft hole 454. The first shaft hole 453 and the second shaft hole 454 are spaced apart along the length direction of the swing arm 45. Specifically, the first shaft hole 453 is provided at the first end 451, and the second shaft hole 454 is provided at the second end 452. The first end 451 is sleeved on the outer periphery of the input shaft 54. Further, the first end 451 is sleeved on the outer periphery of the end of the input shaft 54 facing away from the first gear 52 through the first shaft hole 453.
[0156] The transmission member 40 further includes a rotating shaft 46. The rotating shaft 46 is disposed through the second shaft hole 454, and is fixedly connected to one end of the piston rod 334 facing away from the piston 333, and the second shaft hole 454 of the swing arm 45 can rotate around the rotating shaft 46. When the piston rod 334 moves along its length direction, it drives the swing arm 45 to swing, and the swing arm 45 drives the input shaft 54 to rotate, thereby driving the first gear 52 to rotate, and further driving the rotating assembly 20 to rotate through the speed change gear set 56, the second gear 53 and the output shaft 55.
[0157] Please refer to Figure 27 and Figure 28 , Figure 28 is Figure 27 a partial structural schematic diagram of the rotary grill 100 in another state.
[0158] When the ambient temperature around the rotary grill 100 rises, the fluid in the fluid chamber 31 expands due to heat, and enters the hydraulic cylinder 33 through the connecting pipe 32, thereby pushing the piston 333 to move towards the cylinder head 332 direction, so as to drive the piston rod 334 to move away from the cylinder barrel 331 direction. When the piston rod 334 moves away from the cylinder barrel 331 direction, the piston rod 334 drives the second end portion 452 of the swing arm 45 to move away from the hydraulic cylinder 33 direction through the rotating shaft 46, so that the swing arm 45 makes a clockwise movement with the input shaft 54 as the center, thereby driving the first gear 52 to rotate, and further driving the rotating assembly 20 to rotate through the speed change gear set 56, the second gear 53 and the output shaft 55.
[0159] When the swing arm 45 makes a clockwise movement, the axis of the hydraulic cylinder 33 will produce a yaw, and the setting of the ear plate hole 351 and the pin shaft 352 allows the above yaw to occur freely, avoiding the clockwise movement of the swing arm 45 being locked due to limited yaw.
[0160] In this embodiment, by providing the swing arm 45 between the hydraulic cylinder 33 and the input shaft 54, the linear motion of the piston rod 334 can be converted into the rotation of the input shaft 54 through the swing arm 45, thereby realizing the rotation of the rotating basket 24, which can further simplify the structure of the rotary grill 100 and save the manufacturing cost.
[0161] It should be noted that other structures and connection relationships in this embodiment can refer to the relevant descriptions of the previous embodiment, and will not be elaborated here.
[0162] The embodiments of the present application have been introduced in detail above. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
