Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to a stirring-type automatic cooking machine. Background Technology

[0002] In today's fast-paced life, household kitchen appliances are showing a clear trend towards automation and intelligence, and the demand for efficiency and convenience in the cooking field continues to grow. Traditional manual stir-frying requires a lot of time and effort, and the cooking results depend on the operator's experience, making it difficult to guarantee consistency. This has significant limitations for busy people, cooking novices, and the standardization needs of the catering industry. Against this backdrop, automatic cooking equipment such as stirring automatic stir-fry machines have emerged, but existing products still have key shortcomings.

[0003] Existing automatic stir-fry machines generally face two major problems: First, the spatial layout is unreasonable, with functional components scattered, resulting in a large overall space occupation of the equipment, making it difficult to adapt to the needs of small and medium-sized kitchens; second, the cooking process cannot be executed continuously, making it difficult to achieve seamless switching between steps such as putting in ingredients, stir-frying ingredients, and cleaning.

[0024] Please refer to Figures 1 to 6. The present invention provides a stirring type automatic cooking machine, including a frame 1, a stirring mechanism 2, a lifting mechanism 3, and a rocker arm mechanism 4.

[0025] The frame 1 is used to support other components on the ground. The frame 1 has a first frame 11 and a second frame 15, which are arranged side-by-side horizontally and connected to each other. The top surface of the first frame 11 is higher than the top surface of the second frame 15. Both the top surfaces of the first frame 11 and the second frame 15 have slots. An induction cooker 11 is installed in the slot of the first frame 11, and a pot body 12 is provided on the upper surface of the induction cooker 11. A water tank 13 is installed in the slot of the second frame 15. A first connecting plate 101 is installed in the first frame 11, located below the induction cooker 11. The first end of the lifting mechanism 3 is connected to the first connecting plate 101, and the second end of the lifting mechanism 3 is located above the first end and connected to a second connecting plate 402. The second end of the lifting mechanism 3 can rise and fall relative to the first end. The first end of the rocker arm mechanism 4 is mounted on the second connecting plate 402, and the second end of the rocker arm mechanism 4 can swing relative to the first end. The stirring structure is connected to the second end of the rocker arm mechanism 4. The lifting mechanism 3 is used to drive the second connecting plate 402, the rocker arm mechanism 4 and the stirring mechanism 2 to rise and fall relative to the first connecting plate 101, so that the second connecting plate 402 has an upper limit position and a lower limit position.

[0026] The rocker arm mechanism 4 is used to drive the stirring mechanism 2 to swing between the water tank position directly above the water tank 13 and the stirring position directly above the pot body 12 when the connecting plate is at its upper limit position. The stirring mechanism 2 is used to extend into the pot body 12 to the stirring position when the second connecting plate 402 is at its lower limit position to stir the food inside the pot body 12; the stirring position of the stirring mechanism 2 is located directly below the stirring position of the stirring mechanism 2.

[0027] Please see this application. Figure 1In use, first, control the lifting mechanism 3 to drive the second connecting plate 402, the rocker arm mechanism 4, and the stirring mechanism 2 to rise relative to the first connecting plate 101. At this time, the pot lid 23 is open relative to the pot body 12, the second connecting plate 402 is at its upper limit position, and the rocker arm mechanism 4 is basically in a vertical state. Then, control the rocker arm mechanism 4 to drive the stirring mechanism 2 to move to the water tank position directly above the water tank 13, so that the user can easily add ingredients to the pot body 12. After the ingredients are added, control the rocker arm mechanism 4 to return to the stirring position directly above the pot body 12. Then, the lifting mechanism 3 drives the rocker arm mechanism 4 and the stirring mechanism 2 to descend, so that the stirring mechanism 2 reaches the stirring position. At this time, the second connecting plate 402 is at its lower limit position, and the pot lid 23 is closed on the pot body 12. Then, the stirring mechanism 2 and the induction cooker 11 are started to realize automatic cooking. After that, the lifting mechanism 3 drives the second connecting plate 402, the rocker arm mechanism 4, and the stirring mechanism 2 to rise relative to the first connecting plate 101. Then, the rocker arm mechanism 4 drives the stirring mechanism 2 to move to the water tank position directly above the water tank 13 to facilitate cleaning of the stirring mechanism 2. It is understood that adding seasonings can also be achieved through the above process.

[0028] In one embodiment, the lifting mechanism 3 and the rocker arm mechanism 4 are installed alternately on the second connecting plate 402. In one embodiment, the pot body 12 can be placed at the marked location on the induction cooker 11, or it can be limited by an annular limiting protrusion. In one embodiment, a storage cabinet 14 is installed inside the first frame 11, and the storage cabinet 14 is located below the induction cooker 11. The storage cabinet 14 facilitates the placement of other cooking tools and tableware, thereby improving space utilization. To facilitate the replacement of the induction cooker 11 and the sink 13, the induction cooker 11 and the sink 13 can adopt a modular design. The induction cooker 11 is detachably installed in the empty slot of the first frame 11, and the sink 13 is detachably installed in the empty slot of the second frame 15.

[0029] The stirring mechanism 2, lifting mechanism 3, and rocker arm mechanism 4 can also be modularly designed for easy cleaning and replacement.

[0030] In one embodiment, such as Figure 3As shown, the stirring mechanism 2 includes a connecting frame 22, a pot lid 23, a top cover 21, a supporting plate 26, a first motor 24, a stirring shaft 25, and stirring blades 28. The connecting frame 22 is annular and fixed to the second end of the rocker arm mechanism 4; the pot lid 23 includes a cylindrical upper cover body 231 and a lower cover body 232 fixed below the upper cover body 231. The inner diameter of the lower cover body 232 gradually increases in the direction away from the upper cover body 231 (the lower cover body 232 can be an inverted bowl shape). The connecting frame 22 is clamped to the upper cover body 231 of the connecting frame 22 and abuts against the upper surface of the lower cover body 232; the top cover 21 is fixed to the top surface of the upper cover body 231, and the edge of the top cover 21 extends beyond the outer periphery of the upper cover body 231 and abuts against... The first motor 24 is installed in the installation space 20. The first motor 24 is connected to the connecting frame 22. The first motor 24 is connected to the stirring shaft 25 that passes through the first through hole 261. The stirring blade 28 is fixed to the stirring shaft 25 and located below the supporting plate 26. The first motor 24 is used to drive the stirring shaft 25 and the stirring blade 28 to rotate.

[0031] In one embodiment, the first motor 24 is connected to the stirring shaft 25 via a motor connector 241. The upper end of the motor connector 241 is fixedly connected to the lower surface of the first motor 24, and the lower end has a keyway for connection with the stirring shaft 25. Preferably, the top cover 21 is installed on the upper surface of the outer side of the pot lid 23, and when the cooking machine is working, the oil fumes are discharged outside the pot through small holes on the upper cover 231 and the exhaust cover 21.

[0032] Please see Figure 2-3 In this embodiment, the connecting frame 22 can clamp the upper cover 231 and is sandwiched between the upper surface of the lower cover 232 and the top cover 21, thereby facilitating disassembly and assembly while improving the stability of the stirring mechanism 2. Since the first motor 24 is installed within the installation space 20 formed by the supporting plate 26 and the upper cover 231, it is convenient to disassemble and assemble the first motor 24 and improve the stability of the first motor 24.

[0033] Further, please see Figure 3-4 The stirring mechanism 2 also includes a bearing housing 27, a first curved path sealing fixed plate 272, and a first curved path sealing moving plate 252. For example... Figure 3As shown, the bearing seat 27 is mounted on the support plate 26 and passes through the first through hole 261. The support seat has a second through hole 273 extending through the support plate 26 along its thickness direction. A first bearing 271, sleeved on the stirring shaft 25, is fixed inside the second through hole 273. An annular felt hole located below the first bearing 271 is recessed in the inner wall of the second through hole 273. An annular felt sealing structure 251, sleeved on the stirring shaft 25, is provided inside the felt hole. The first curved path sealing plate 272 is mounted on the lower side of the bearing seat 27. The first curved path sealing plate 272 extends through the support seat 273 along its thickness direction. A third through hole communicating with the second through hole 273 is provided. The stirring shaft 25 passes through the third through hole. The inner sidewall of the third through hole is recessed with a plurality of first annular sealing grooves. The plurality of first annular sealing grooves are spaced apart along the length direction of the stirring shaft 25. The first curved path sealing moving plate 252 is annular and sleeved and fixed on the outer side of the stirring shaft 25. The outer side of the first curved path sealing moving plate 252 is provided with a plurality of annular first sealing protrusions 2721. The plurality of annular first sealing protrusions 2721 are spaced apart along the axial direction of the first curved path sealing moving plate 252. The plurality of annular first sealing protrusions 2721 extend into the plurality of first annular sealing grooves.

[0034] In one embodiment, such as Figure 3 As shown, the downward force of the stirring shaft 25 can be transmitted to the support plate 26 and then to the pot lid 23, thereby reducing the burden on the first motor 24. The lower surface of the upper end of the bearing seat 27 is connected to the upper surface of the support plate. The lower end of the bearing seat 27 is in contact with the outer ring of the first bearing 271, and the inner ring of the first bearing 271 is in contact with the stirring shaft 25. The stirring blades 28 are mounted on the bottom end of the stirring shaft 25. The curved stirring blades 28 fit against the inner wall of the pot body 12 with a gap, which can continuously push the food and effectively scrape off the food adhering to the pot wall, improving the uniformity of heating of the food and the efficiency of cooking, thus enabling the production of high-quality food faster.

[0035] By setting the felt hole and the felt sealing structure 251, a seal can be achieved using the felt sealing structure 251. By setting the first sealing protrusion 2721 and the first annular sealing groove, a curved path seal can be achieved. Thus, a double seal can be achieved for the stirring shaft 25, thereby preventing the juice of the food from entering the first motor 24 and affecting the operation of the first motor 24.

[0036] To improve stirring effect, reduce noise, and avoid food residue in the pot 12 after cooking, the stirring blade 28 includes a first stirring part 281, a first support part 282, a second support part 283, and a second stirring part 284, which are fixedly connected in sequence. The second support part 283 is fixedly connected to the stirring shaft 25. When the stirring mechanism 2 is in the stirring position, the first support part 282 and the second stirring part 284 both extend horizontally, while the second support part 283 and the stirring shaft 25 both extend vertically. The first stirring part 281 is located below the first support part 282, and the shape of the lower edge of the first stirring part 281 is adapted to the shape of the inner side of the pot 12, and a gap is formed between it and the inner side of the pot 12.

[0037] Since the shape of the lower edge of the first stirring part 281 is adapted to the shape of the inner side of the pot body 12, food residue in the pot body 12 can be avoided after cooking. At the same time, the first stirring part 281 and the second stirring part 284 are provided to improve the stirring efficiency and make the ingredients more thoroughly stirred.

[0038] To ensure the stability of the stirring mechanism 2 during the lifting process, the lifting mechanism 3 in this application adopts a screw drive. The lifting mechanism 3 includes a housing 30 and a slider 34. The housing 30 is mounted on the first connecting plate 101, and the connection point between the housing 30 and the first connecting plate 101 is the first end of the lifting mechanism 3. A second motor 301 is mounted on the lower end of the housing 30. A first guide rod 36, a second guide rod 37, and a screw shaft 35 are provided vertically inside the housing 30. The two ends of either the first guide rod 36 or the second guide rod 37 are fixedly connected to the upper and lower side walls of the housing 30, respectively. The two ends of the screw shaft 35 are rotatably connected to the upper and lower side walls of the housing 30, respectively. The slider 34 has a first sliding hole, a second sliding hole, and a lead screw hole that pass through it vertically. The first guide rod 36 passes through the first sliding hole and is slidably engaged with it. The second guide rod 37 passes through the second sliding hole and is slidably engaged with it. The thread on the inner sidewall of the lead screw hole is slidably engaged with the thread on the outer sidewall of the lead screw shaft 35. The slider 34 is connected to the second connecting plate 402. The second motor 301 is used to drive the lead screw shaft 35 to rotate, so as to drive the slider 34 and the second connecting plate 402 to rise and fall vertically. The connection point between the slider 34 and the second connecting plate 402 is the second end of the lifting mechanism 3.

[0039] In this embodiment, transmission can be achieved through the cooperation between the slider 34 and the lead screw 35. The arrangement of the first guide rod 36 and the second guide rod 37 can improve the stability of the slider 34 during operation.

[0040] In one embodiment, the housing 30 includes a sliding side plate 31, an upper plate 32, and a lower plate 33. The upper plate 32 and the lower plate 33 are located at the upper and lower ends of the sliding side plate 31, respectively. Preferably, the housing 30 includes a sliding side plate 31 extending vertically, and the slider 34 is slidably engaged with the sliding side plate 31 and used for sliding up and down along the sliding side plate 31. This engagement between the slider 34 and the sliding side plate 31 improves the stability of the slider 34's sliding motion.

[0041] In one embodiment, a deep groove ball bearing 322 is installed inside the upper plate 32. The inner ring of the deep groove ball bearing 322 contacts the lead screw shaft 35, thereby reducing the frictional force during the rotation of the lead screw shaft 35. A bearing cap 321 may be provided on the deep groove ball bearing 322.

[0042] In one embodiment, the lifting mechanism 3 further includes a support frame 38. The support frame 38 is fixed inside the housing 30 and located below the slider 34. The support frame 38 has a fourth through hole extending through the axial direction of the lead screw shaft 35, and a second bearing 381 is embedded in the fourth through hole. The lead screw shaft 35 includes an upper shaft section 353 and a lower shaft section 354 connected to the lower end of the upper shaft section 353. The diameter of the lower shaft section 354 is smaller than the diameter of the upper shaft section 353. An annular stepped surface 355 is formed between the lower shaft section 354 and the upper shaft section 353. The annular stepped surface 355 of the lead screw shaft 35 abuts against the second bearing 381, and the second bearing 381 is sleeved on the lower shaft section 354.

[0043] In one embodiment, the second bearing 381 is a thrust ball bearing. The outer ring of the second bearing 381 contacts the support frame 38, and the inner ring contacts the lead screw shaft 35. By having the annular stepped surface 355 of the lead screw shaft 35 abut against the second bearing 381, the weight of the lead screw shaft 35 can be borne by the support frame 38, thereby preventing the weight of the lead screw shaft 35 from directly acting on the second motor 301, thus improving the operational stability of the second motor 301.

[0044] like Figure 5As shown, in one embodiment, the output shaft of the second motor 301 is connected to the lead screw shaft 35 via a coupling 39. To improve the sealing effect at the lead screw shaft 35, the lifting mechanism 3 further includes a second curved path sealing fixed plate 351 and a second curved path sealing moving plate 352. The second curved path sealing plate 351 is installed on the lower side of the support frame 38. The second curved path sealing plate 351 has a fifth through hole communicating with the fourth through hole along the thickness direction of the second curved path sealing plate 351. The lower shaft section 354 passes through the fifth through hole. The inner sidewall of the fifth through hole is recessed with a plurality of second annular sealing grooves. The plurality of second annular sealing grooves are spaced apart along the length direction of the stirring shaft 25. The second curved path sealing moving plate 352 is annular and sleeved and fixed on the outer side of the lower shaft section 354. The outer side of the second curved path sealing moving plate 352 is provided with a plurality of annular second sealing protrusions. The plurality of annular second sealing protrusions are spaced apart along the axial direction of the second curved path sealing moving plate 352. The plurality of annular second sealing protrusions extend into the plurality of second annular sealing grooves.

[0045] like Figure 5 As shown, the cooperation between the second curved path sealing fixed plate 351 and the second curved path sealing moving plate 352 can realize the curved path seal between the second curved path sealing fixed plate 351 and the second curved path sealing moving plate 352, thereby preventing the food juice from flowing into the second motor 301 and affecting the operation of the second motor 301.

[0046] In order to automatically clean the food juice on the stirring mechanism 2, this embodiment is provided with a rocker arm mechanism 4 to drive the stirring mechanism 2 to move to the water tank position directly above the water tank 13.

[0047] Please see Figure 6 The rocker arm mechanism 4 includes a third motor 401 and a rocker arm 41. The third motor 401 is mounted on the second connecting plate 402, and the connection point of the third motor 401 to the second connecting plate 402 is the first end of the rocker arm mechanism 4. The third motor 401 is connected to the first end of the rocker arm 41 and is used to drive the rocker arm to swing. The second end of the rocker arm 41 is fixedly connected to the stirring mechanism 2, and the second end of the rocker arm 41 is the second end of the rocker arm mechanism 4.

[0048] In this application, by setting a third motor 401, the position of the stirring mechanism 2 can be precisely controlled, thereby achieving a thorough rinsing of the stirring mechanism 2. During the rinsing process of the stirring mechanism 2, the lifting mechanism 3 and the rocker arm mechanism 4 can cooperate with each other to improve the rinsing effect.

[0049] In one embodiment, such as Figure 6As shown, the connecting block 42 has a protruding hollow round tube on its side, which is connected to the rocker arm 41. The rotating shaft of the third motor 401 is engaged with the through hole inside the connecting block 42. The fixing member 43 is engaged with the rotating shaft of the third motor 401 and fixed on the connecting block 42. The motor II 401 is connected to the second connecting plate 402.

[0050] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the scope of protection of the present invention.
