Description

Technical Field

[0001] This invention relates to the field of automatic cooking equipment technology, specifically to a cookware cleaning device for an automatic stir-fry machine, which is particularly suitable for automatically scrubbing the inner wall of the wok after cooking. Background Technology

[0002] With the fast pace of life and rising labor costs, automatic cooking machines, as intelligent kitchen equipment, are being used more and more widely. In automatic cooking machines, after the wok finishes cooking one dish, oil and food residue remain on the inner wall, requiring cleaning before cooking the next dish. Automatic cleaning of the wok is one of the key factors affecting the continuous operation efficiency and food safety of automatic cooking machines.

[0003] To achieve automatic cleaning of woks, several cleaning solutions have been proposed in existing technologies. For example, some solutions use steel balls as the cleaning medium. The steel balls are placed inside the wok, and the rotation or vibration of the wok causes the steel balls to collide and rub against the wok wall, thereby removing oil and residue. Other solutions use a spraying method, rinsing the wok with high-pressure water jets. In addition, some solutions use brushes to scrub the wok wall.

[0004] However, all of the above-mentioned existing technical solutions have varying degrees of drawbacks:

[0005] First, the steel ball cleaning solution has problems with cleaning dead spots and long cleaning time. The inner wall of a wok usually has raised bumps for turning food during cooking. When the steel ball rolls inside the wok, it easily gets stuck on these bumps, failing to reach the area around them and creating cleaning dead spots. Furthermore, the cleaning effect of the steel ball relies on prolonged rolling friction, typically requiring up to 15 minutes to complete one cleaning cycle, severely impacting the continuous operation efficiency of automatic cooking machines.

[0006] Secondly, the spray cleaning method has limited effectiveness in removing stubborn oil stains. Simply relying on high-pressure water jets is insufficient to effectively remove charred oil stains and carbonized residues adhering to the pot walls. Incomplete cleaning will leave residues that affect the taste and food safety of the next dish.

[0007] Third, the existing brush cleaning solutions have fixed brush movement trajectories, which cannot conform to the curved inner wall of the pot. The inner wall of a wok is usually hemispherical or curved. In existing brush cleaning solutions, the movement trajectory of the brush is mostly a single straight line up and down or horizontal rotation. The brush cannot move along the curved trajectory of the pot wall, resulting in incomplete contact between the brush and the pot wall, and the curved area of ​​the pot wall is not thoroughly cleaned.

[0008] In summary, existing automatic cooking machine cookware cleaning technologies have several drawbacks when applied to automatic wok cleaning, including "steel ball cleaning leaving blind spots and being time-consuming," "limited spray cleaning effectiveness," and "brushes unable to conform to the curved trajectory of the wok wall." Therefore, there is an urgent need in this field for a cookware cleaning device that offers high cleaning efficiency, eliminates blind spots, and allows brushes to move along the curved trajectory of the wok wall. Summary of the Invention

[0009] The purpose of this invention is to provide a cookware cleaning device for an automatic cooking machine, which aims to solve the technical problems of existing automatic cooking machines where steel ball cleaning has blind spots and takes a long time, and the brush cannot conform to the arc trajectory of the pot wall, resulting in incomplete cleaning.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] An automatic cooking machine's cookware cleaning device includes a mounting housing, a brush mechanism, a lifting drive mechanism, a rotating drive mechanism, and a guide rail mechanism. The mounting housing is positioned below the cooking pot. The brush mechanism is mounted on the mounting housing and used to scrub the inner wall of the cooking pot. The lifting drive mechanism is connected to the brush mechanism and drives the brush mechanism to rise into the interior of the cooking pot or descend below it. The rotating drive mechanism is connected to the brush mechanism and drives it to rotate. The guide rail mechanism is mounted on the mounting housing and guides the brush mechanism along a trajectory along the inner wall of the cooking pot.

[0012] Preferably, the lifting drive mechanism includes a cylinder, a connecting rod, and a push rod. The cylinder drives the connecting rod to move, the connecting rod drives the push rod to move, and the push rod passes through the mounting housing and is connected to the brush mechanism.

[0013] Preferably, the guide rail mechanism includes a guide rail and a brush slide rail disposed on the mounting housing. The guide rail has a guide groove, and the push rod passes through the guide groove and moves along the guide groove to guide the movement path of the brush mechanism. The brush slide rail is a vertically arranged track, and the bushing of the brush mechanism moves along the brush slide rail.

[0014] Preferably, the guide rail includes a vertical section and an inclined section. When the push rod moves along the vertical section, the brush mechanism moves vertically up and down. When the push rod moves along the inclined section, the brush mechanism moves towards the center of the wok.

[0015] Preferably, the brush mechanism includes a brush head, a brush rod, and a rotating rod. The brush head is connected to the upper end of the brush rod, the brush rod is inserted into the rotating rod, and the rotating rod is connected to the rotary drive mechanism.

[0016] Preferably, the rotating rod is connected to the rotary drive mechanism via a universal joint, which is composed of multiple sub-universal joints connected in sequence.

[0017] Preferably, the brush mechanism includes a horizontal brush group and a mushroom-shaped brush group disposed above the horizontal brush group, the mushroom-shaped brush group being arranged to spread outwards for cleaning the arc-shaped inner wall of the wok.

[0018] Preferably, it also includes a waterproof protective plate, which is vertically and flexibly mounted on the mounting housing. When the waterproof protective plate is raised, its edge abuts against the edge of the wok to prevent water splashing during the cleaning process.

[0019] Preferably, the brush mechanism is provided with a nozzle for spraying detergent onto the brush mechanism; the mounting housing is also provided with a spraying device for spraying clean water into the wok.

[0020] Preferably, the mounting housing is a hollow structure with a drain outlet at the bottom for collecting and discharging wastewater after cleaning.

[0021] The present invention has the following beneficial effects:

[0022] First, the cleaning efficiency is greatly improved. This invention uses a brush mechanism to scrub the inner wall of the wok. Compared with the steel ball cleaning method, which requires 15 minutes of cleaning time, this invention can complete a cleaning in only about 30 seconds, improving the cleaning efficiency by about 30 times and significantly improving the continuous operation efficiency of the automatic cooking machine.

[0023] Secondly, it ensures thorough cleaning without any blind spots. Guided by a guide rail mechanism, the brush mechanism moves along the inner wall of the wok, keeping the brushes in constant contact with the wall. The brush mechanism includes horizontal brush groups and mushroom-shaped brush groups. The horizontal brush groups clean the flat areas of the wok bottom, while the mushroom-shaped brush groups extend outwards to clean the curved areas of the wok wall, achieving thorough cleaning of the entire inner wall of the wok without any blind spots and avoiding the problem of steel balls getting stuck on the stirrups.

[0024] Third, the brush's movement trajectory is precisely controllable. The guide rail mechanism includes a vertical section and an inclined section. During the lifting and lowering process, the brush first rises vertically along the vertical section, and then moves towards the center of the wok along the inclined section, thus allowing the brush to move along the curved inner wall of the wok, achieving full contact between the brush and the wok wall. This design ensures that the brush remains in contact with the wok wall throughout its ascent, resulting in a uniform and consistent cleaning effect.

[0025] Fourth, the transmission structure is compact and adaptable to arc-shaped movements. The rotary drive mechanism and the brush mechanism are connected by a universal joint, which is composed of multiple sub-universal joints connected in sequence. This allows it to adapt to the angle changes of the brush during its arc-shaped movement along the pot wall, avoiding the problem of rigid transmission jamming during arc-shaped movements. At the same time, the entire cleaning device can be installed below the wok, maximizing space utilization and not occupying additional operating space.

[0026] Fifth, the waterproof and drainage design is comprehensive. The waterproof protective plate rises and abuts against the edge of the wok during cleaning to prevent water splashing. The mounting shell has a hollow structure with a drain outlet at the bottom, allowing wastewater generated during cleaning to be collected and discharged, keeping the equipment clean.

[0027] Sixth, the cleaning and disinfection functions are integrated. The brush mechanism is equipped with a nozzle to spray detergent, and the housing contains a spray device to spray clean water, allowing for simultaneous brushing and rinsing. In addition, a disinfectant spray nozzle can be installed to disinfect the wok, ensuring food safety.

[0028] In summary, this invention provides a complete and systematic solution, encompassing the lifting and rotating drive of the brush, the guide rail, the arc-shaped motion adaptation, and waterproofing and drainage. The coordinated operation of each structure ensures the efficiency, thoroughness, and reliability of the wok cleaning process. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Example 1: Overall Structure of the Cookware Cleaning Device for an Automatic Cooking Machine

[0050] like Figure 1 , Figure 8 As shown, the present invention provides a cookware cleaning device for an automatic cooking machine, including a mounting housing 1, a brush mechanism 3, a lifting drive mechanism 4, a rotating drive mechanism 5, and a guide rail mechanism 6.

[0051] The mounting housing 1 is located below the wok 2. When cooking, the wok 2 faces upward (to the food receiving and cooking positions), and when cleaning, it faces downward (to the cleaning positions). The mounting housing 1 is preferably a hollow structure, with a cylindrical upper part and a conical lower part, and the hollow interior forming an accommodating space.

[0052] The brush mechanism 3 is mounted on the mounting housing 1 and is used to scrub the inner wall of the wok 2. In the non-working state, the brush mechanism 3 is located inside the mounting housing 1; in the working state, it rises into the wok 2.

[0053] The lifting drive mechanism 4 is connected to the brush mechanism 3 and is used to drive the brush mechanism 3 to rise into the wok 2 or to fall below the wok 2.

[0054] The rotary drive mechanism 5 is connected to the brush mechanism 3 and is used to drive the brush mechanism 3 to rotate. During the cleaning process, the wok 2 itself is also rotating, and the rotation direction of the brush mechanism 3 is opposite to that of the wok 2, thereby achieving efficient cleaning.

[0055] The guide rail mechanism 6 is mounted on the mounting housing 1 and is used to guide the brush mechanism 3 to move along the inner wall trajectory of the wok 2. Example 2: Structure of the lifting drive mechanism

[0056] like Figure 2 and Figure 4 As shown, the lifting drive mechanism 4 includes a cylinder 41, a connecting rod 42, and a push rod 43. The cylinder 41 is located on the outer wall of the mounting housing 1. The cylinder 41 is a rodless cylinder (slide table type). The slider of the cylinder 41 drives the connecting rod 42 to move, and the connecting rod 42 drives the push rod 43 to move. The push rod 43 passes through the mounting housing 1 and connects to the brush mechanism 3. Specifically, one end of the push rod 43 passes through the guide rail 61 and extends into the interior of the mounting housing 1, where it is clamped to the bushing 34 of the brush mechanism 3, thus achieving a fixed connection between the push rod 43 and the brush mechanism 3, enabling the push rod 43 to drive the brush mechanism 3 to move along the guide rail 61.

[0057] The push rod 43 is equipped with a limiting mechanism, which is a symmetrically arranged wheel set (limiting wheel set 44). Each wheel set has two wheels, and there is a gap between the two wheels. The gap clamps the guide rail wall to limit and guide the push rod 43, ensuring that the push rod 43 moves along the predetermined path.

[0058] The outer wall of the mounting housing 1 has a groove, and a protective cover is provided at the upper end of the groove. The cavity formed therein is equipped with a cylinder 41. A guide rail 61 is provided on the side wall of the groove. Example 3: Structure of the guide rail mechanism

[0059] like Figure 2 and Figure 3As shown, the guide rail mechanism 6 includes a guide rail 61 disposed on the mounting housing 1. The guide rail 61 has a guide groove 611, and the push rod 43 passes through the guide groove 611 and moves along the guide groove 611 to guide the movement path of the brush mechanism 3.

[0060] The guide rail 61 includes a vertical section 612 and an inclined section 613. The vertical section 612 is located at the lower part of the guide rail 61, and the brush mechanism 3 moves vertically up and down when the push rod 43 moves along the vertical section 612; the inclined section 613 is located at the upper part of the guide rail 61, and the brush mechanism 3 moves towards the center of the wok 2 when the push rod 43 moves along the inclined section 613.

[0061] The guide groove 611 of the guide rail 61 is relatively long, so that during the movement, part of the push rod 43 will enter the guide groove 611 to avoid obstacles.

[0062] A brush slide rail 62 may be provided next to the guide rail 61. The brush slide rail 62 is a vertical track. The lower part of the bushing 34 of the brush rod 32 can move along the brush slide rail 62 through the shaft grooves of the rollers on both sides, so as to keep the center position of the brush mechanism 3 stationary in the initial stage of movement. Subsequently, the brush mechanism 3 enters the inclined section 613, and the lower part of the bushing 34 remains in the brush slide rail 62, thereby keeping it in the same center range as the universal joint 7 at the bottom. Example 4: Structure of the brush mechanism

[0063] like Figure 5 As shown, the brush mechanism 3 includes a brush head 31, a brush rod 32, and a rotating rod 33. The brush head 31 is connected to the upper end of the brush rod 32, the brush rod 32 is inserted into the rotating rod 33, and the rotating rod 33 is connected to the rotary drive mechanism 5.

[0064] The brush head 31 includes a horizontal brush assembly 311 and a mushroom-shaped brush assembly 312 disposed above the horizontal brush assembly 311. The horizontal brush assembly 311 is located at the lower part of the brush head 31 and is used to clean the bottom flat area of ​​the wok 2. The mushroom-shaped brush assembly 312 is located above the horizontal brush assembly 311 and is arranged outwardly (in a mushroom shape) to clean the curved inner wall of the wok 2.

[0065] The brush head 31 is preferably made of high-temperature resistant nylon bristles or stainless steel wire brush, which can withstand the high-temperature environment when cleaning the wok.

[0066] The brush handle 32 is inserted at the top of the rotating rod 33. The inner hole of the rotating rod 33 is hexagonal, which fits into the hexagonal outer wall of the universal joint 7, and can move up and down. The bottom of the rotating rod 33 is provided with a limiting structure to prevent the universal joint 7 from disengaging from the rotating rod 33.

[0067] A bushing 34 is sleeved on the outside of the rotating rod 33, and a bearing 35 is provided between the bushing 34 and the rotating rod 33. A nozzle 9 is provided on the bushing 34, which is used to spray detergent onto the brush mechanism 3. Example 5: Rotary drive mechanism and universal joint

[0068] like Figure 5-6 As shown, the rotary drive mechanism 5 includes a drive motor 51, a pulley 52, and a belt 53. The drive motor 51 is located outside the mounting housing 1, and its drive shaft is connected to the universal joint 7 via a combination of the pulley 52 and the belt 53. The lower part of the universal joint 7 extends through the outside of the mounting housing 1 and connects to the pulley 52.

[0069] Universal link 7 connects the rotating rod 33 and the rotary drive mechanism 5, and is used to transmit the rotary driving force from the drive motor 51 to the brush mechanism 3. Universal link 7 is sleeved with the rotating rod 33 and can move up and down relative to it. The outer wall of universal link 7 is hexagonal and fits into the hexagonal inner hole of the rotating rod 33. Universal link 7 is composed of multiple sub-universal links 71 connected in sequence. Since the brush mechanism 3 needs to make arc motion when moving along the arc of the pot wall, universal link 7 must be a flexible connection (joint), otherwise it will get stuck.

[0070] The transmission principle of the universal joint 7 is as follows: the drive motor 51 drives the universal joint 7 to rotate through the pulley 52 and belt 53. The universal joint 7 drives the rotating rod 33 to rotate through the hexagonal engagement. The rotating rod 33 drives the brush rod 32 and brush head 31 to rotate.

[0071] During the movement of the brush mechanism 3 along the guide rail 61, the multi-section structure of the universal linkage 7 can adapt to the positional changes of the brush mechanism 3 and always maintain the transmission of rotational power. Example 6: Structure of the waterproof protective panel

[0072] like Figure 7 As shown, the present invention also includes a waterproof protective plate 8. The waterproof protective plate 8 is vertically and flexibly mounted on the mounting housing 1, and the waterproof protective plate 8 is connected to a drive cylinder (not shown in the figure). The drive cylinders are symmetrically arranged and are used to drive the waterproof protective plate 8 to move up and down.

[0073] After the waterproof protective plate 8 rises, its upper edge engages with the lower edge of the wok 2 to form a seal, preventing water splashing during cleaning. The waterproof protective plate 8 has a notch 81, the position of which corresponds to the cover of the drive motor 51. The notch 81 provides clearance for the cover of the drive motor 51 when the waterproof protective plate 8 descends. A baffle plate is also provided at the drive motor 51 to further prevent water from entering the motor area.

[0074] In the non-cleaning state, the waterproof protective plate 8 descends and becomes level with the upper end of the mounting housing 1. Example 7: Sprayer Nozzle and Spraying Device

[0075] like Figure 2 As shown, the bushing 34 of the brush mechanism 3 is equipped with a nozzle 9. The nozzle 9 is connected to an external pipeline to supply detergent. The nozzle 9 sprays detergent onto the brush head 31, so as to realize the simultaneous brushing and detergent supply.

[0076] The mounting housing 1 also includes a spray device 10, the main body of which is fixedly installed inside the housing 1. The spray device 10 has a rotating nozzle for spraying clean water into the wok 2, thus rinsing it. A small nozzle is also provided next to the spray device 10 for connecting to disinfectant solution, thereby disinfecting the wok 2.

[0077] During the cleaning process, the wok 2 rotates, the brush mechanism 3 rotates in the opposite direction, the nozzle 9 continuously supplies detergent, and the spray device 10 continuously sprays clean water, achieving brushing and rinsing at the same time. The wastewater after cleaning is collected and discharged through the drain port 11 at the bottom of the housing 1. Example 8: The working process of the device

[0078] The working process of the cookware cleaning device of the automatic cooking machine of the present invention will be described below with reference to the accompanying drawings.

[0079] Step 1: Flip the wok to the cleaning position. After cooking, flip the wok 2 from the top to the bottom (cleaning position), with the wok 2 positioned above the housing 1.

[0080] Step 2: Waterproof protective plate rises. The drive cylinder drives the waterproof protective plate 8 to rise, and the upper edge of the waterproof protective plate 8 engages with the lower edge of the wok 2 to prevent water splashing during the cleaning process.

[0081] Step 3: The brush rises and adheres to the pot wall. The cylinder 41 of the lifting drive mechanism 4 is activated, driving the push rod 43 upward along the guide groove 611 of the guide rail 61 via the connecting rod 42. The push rod 43 first rises vertically along the vertical section 612, and the brush mechanism 3 rises vertically into the wok 2; then the push rod 43 enters the inclined section 613, and moves towards the center of the wok 2, driving the brush mechanism 3 to move towards the center of the wok 2, so that the brush head 31 always adheres to the arc-shaped inner wall of the wok 2.

[0082] During the upward movement of the brush, the horizontal brush group 311 of the brush head 31 first contacts the bottom area of ​​the wok 2, and then the mushroom-shaped brush group 312 contacts the arc-shaped inner wall of the wok 2, achieving full contact from the bottom of the wok to the wall.

[0083] Step Four: The brush rises and rotates simultaneously. As the brush mechanism 3 rises, the drive motor 51 starts, driving the universal joint 7 to rotate via the pulley 52 and belt 53. The universal joint 7 then drives the rotating rod 33 and brush rod 32 to rotate, causing the brush head 31 to rotate accordingly, achieving simultaneous rising and rotating. The wok 2 itself also rotates, but the direction of rotation of the brush head 31 is opposite to that of the wok 2, achieving efficient scrubbing.

[0084] At the same time, the nozzle 9 sprays detergent onto the brush head 31, and the spraying device 10 sprays clean water into the wok 2, achieving simultaneous brushing and rinsing.

[0085] Step 5: Brush descends and resets. After cleaning, the cylinder 41 of the lifting drive mechanism 4 reverses its movement, and the push rod 43 descends sequentially along the inclined section 613 and the vertical section 612 of the guide rail 61, causing the brush mechanism 3 to descend and reset inside the mounting housing 1.

[0086] Step Six: Lowering the Waterproof Protective Plate. The drive cylinder drives the waterproof protective plate 8 to descend and reset, until it is level with the upper end of the mounting housing 1.

[0087] Step 7: Wastewater Discharge. Wastewater generated during the cleaning process is collected and discharged through the drain outlet 11 at the bottom of the housing 1. Example 9: Cleaning Media Supply System

[0088] This invention also relates to a cleaning medium supply system. The supply system includes a hot and cold water tank, a heater, and a pump. The hot and cold water tank has a double-layer structure. The heater is used to heat the cleaning water, and the pump is used to circulate the heated hot water to the spray device 10 and the nozzles 9. By cooperating with the hot and cold water tank and the heater, hot water cleaning can be achieved, improving the decontamination effect. Example 10: Application Scenarios

[0089] The cookware cleaning device of the present invention can be applied to the automatic cleaning of woks in automatic cooking machines.

[0090] After the automatic cooking machine finishes cooking a dish, the wok 2 flips to the cleaning position, and the cleaning device of the present invention is automatically activated. It completes the washing, rinsing and wastewater discharge of the wok in about 30 seconds. Then the wok 2 flips back to the cooking position to cook the next dish.

[0091] Compared to the traditional steel ball cleaning method that requires 15 minutes of cleaning time, this invention significantly shortens the cleaning time and greatly improves the continuous operation efficiency of the automatic cooking machine. At the same time, the brush mechanism 3 moves along the trajectory of the pot wall to achieve thorough cleaning without blind spots, avoiding the problem of steel balls getting stuck on the stirrups.

[0092] Industrial applicability

[0093] The automatic cooking machine of this invention features a rationally designed and highly efficient cookware cleaning device. It effectively solves the technical problems of existing cookware cleaning technologies, such as the blind spots and time-consuming steel ball cleaning, and the inability of brushes to conform to the curved trajectory of the cookware wall. The various mechanisms of the device work together seamlessly, achieving a high degree of automation and strong adaptability, making it widely applicable to the automatic cleaning of woks in various automatic cooking machines. Its guide rails guide the brushes along the cookware wall trajectory, achieving thorough cleaning; the universal linkage transmission adapts to angle changes during curved movement; the waterproof protective plate and drainage design ensure cleanliness and safety during the cleaning process; and the coordination of the nozzles and spraying device enables simultaneous brushing and rinsing. The above-mentioned structural design has reasonable manufacturing costs, is easy to maintain, and possesses significant industrial practical value and promising prospects for widespread application.
