Description

Technical Field

[0001] The present invention relates to the field of kitchenware, in particular to a commercial kitchen stove. Background Art

[0002] Traditional noodle cooking equipment often utilizes a single pot and heat source, requiring manual operation to sequentially complete the water filling, feeding, temperature control, and scooping processes. While this method can meet the needs of families or small-batch production, it has significant drawbacks in high-intensity applications such as commercial kitchens, fast food chains, and noodle shops. A single pot can only cook one type of noodle at a time, failing to meet customers' immediate demand for diverse dishes and leading to long queues during peak hours. Furthermore, manual operations such as feeding, timing, and scooping require repetitive manual work, which is labor-intensive and prone to quality fluctuations due to fatigue.

[0003] To improve efficiency, existing technologies have proposed multi-cavity integrated noodle cooking devices. For example, patent CN205162759U discloses a portable noodle cooker that uses parallel partitions to divide the pot into multiple independent cooking chambers and is equipped with independent induction cookers to achieve temperature control in each chamber. Although this solution supports cooking different types of noodles simultaneously, it still has the following shortcomings:

[0004] 1. The cooking chambers are designed with a linear arrangement, requiring the operator to frequently move along the long axis to monitor the status of each chamber, resulting in inefficient spatial layout;

[0005] 2. Each cavity lacks an intelligent time feedback module, and people rely on experience to judge the cooking end point of different pasta. During peak periods, it is easy for attention to be distracted, resulting in overcooking or undercooking. Summary of the Invention

[0006] In view of this, the present invention proposes a commercial kitchen stove with high space utilization and intelligent time-sharing control to solve the above technical problems.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] A commercial kitchen stove comprises: a shell, wherein at least one mounting frame is fixedly arranged at intervals in the upper and lower parts of the shell; a pot body assembly, wherein the pot body assembly comprises a cylinder, a heating unit, an outer cover plate and a supporting cover plate, wherein the cylinder is vertically fixed in the mounting frame, the heating part of the heating unit is arranged at the bottom of the cylinder or directly below the cylinder, the outer cover plate is fixed in the mounting frame around the upper opening of the cylinder, and a Hall sensor is provided on the outer cover plate, the supporting cover plate can be rotatably covered on the upper opening of the cylinder, and its outer circumference is fixedly connected to the outer gear ring, and at least three evenly distributed Placement holes, the placement holes are used to fix the net bag, and the outer edge of the outer cover plate is provided with a position identifier corresponding to each placement hole; a driving component, the driving component includes a motor and a driving gear, the motor is fixed to the side of the mounting frame, and its output shaft passes through the outer cover plate through a sealed bearing and is connected to the driving gear, and the driving gear is meshed with the outer gear ring; and a control device, including a controller and an operation panel, the controller is electrically connected to the Hall sensor and the motor, and through the control of the operation panel, based on the feedback signal of the Hall sensor to the position identifier, the support cover plate is controlled to rotate to a preset angle.

[0009] To better implement the above technical solution, optionally, the drive assembly further includes a driven gear, which is rotatably mounted above the outer cover plate through a bearing and meshes with the outer gear ring.

[0010] Optionally, the control device further includes an indicator light and a voice alarm, and the signal input ends of the indicator light and the voice alarm are respectively connected to the signal output end of the controller.

[0011] Optionally, the bottom surface of the supporting cover plate is provided with a downwardly extending raising ring, the bottom surface of the raising ring is provided with a plurality of rollers at intervals, and the outer cover plate is provided with a guide ring groove for the rollers to move.

[0012] Optionally, the supporting cover is provided with positioning protrusions located beside each placement hole, and the outer edge of the net bag is provided with positioning grooves that cooperate with the positioning protrusions.

[0013] Optionally, a faucet for injecting water into the cylinder is provided on the outer cover plate, and a water inlet end of the faucet is connected to an external water source.

[0014] Optionally, an overflow hole is provided on the outer cover plate, and the overflow hole is connected to an external discharge pipe.

[0015] Optionally, there is a gap between the driving gear and the driven gear and the top surface of the outer cover plate.

[0016] Beneficial effects of the present invention:

[0017] The commercial kitchen stove of the present invention supports the parallel processing of multiple types of food without interfering with each other, fundamentally solving the problem of the limitation of the same type of food caused by the single cavity of the traditional cooking pot. When processing noodles (rice noodles) and dumplings at the same time, multiple independent net bag bearing structures can be used in conjunction with the placement holes distributed in a ring array to achieve precise time-sharing independent control based on the differentiated cooking time requirements of different noodle types or filling formulas, avoiding the problem of overcooking or undercooking caused by mixed cooking, and realizing time-sharing control so that noodles (rice noodles) and dumplings can be processed simultaneously.

[0018] The commercial kitchen stove of the present invention can execute independent operation instruction response, timing parameter setting and cooking status feedback for each net bag, accurately record the real-time cooking time of each net bag, and trigger an alarm instruction when the preset time threshold is reached. It adopts a rotation method to realize the operation of feeding and discharging materials of a single net bag. Compared with the traditional manual timing method, this automated control solution significantly improves the accuracy and efficiency of multi-tasking processing, and at the same time increases the feasibility of adding more net bags to the system.

[0019] The commercial kitchen stove of the present invention improves space utilization by providing a double-layer pot body assembly, further enhances the feasibility of adding a net bag, and thereby increases shipment volume.

[0020] The commercial stove of this invention boasts a high degree of automation, allowing a single pot to cook multiple bowls of noodles simultaneously. Operators require no specialized training or industry experience. Through the coordinated feedback of a Hall effect sensor and a position detector, the support cover precisely rotates to a preset angle to assist in the noodle scooping process. This simple configuration of the operating panel replaces the traditional, complex process of relying on empirical judgment to determine doneness and quantitatively scoop out noodles, significantly reducing staffing requirements and labor costs.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments, wherein the same components are represented by the same reference numerals.

[0028] See also Figures 1 to 4 The embodiment of the present invention discloses a commercial kitchen stove, including a shell 10, a pot body assembly, a driving assembly and a control device.

[0029] like Figure 4 As shown, at least one mounting frame 11 is fixedly provided at upper and lower intervals inside the shell 10. In this embodiment, there are two mounting frames 11, and each mounting frame 11 corresponds to a set of pot body components. The double-layer frame structure nearly doubles the space utilization rate of traditional single-layer equipment, which meets the three-dimensional layout requirements of commercial kitchens.

[0030] like Figure 2-Figure 4 As shown, the pot body assembly includes a cylinder 21, a heating unit 22, an outer cover 23 and a supporting cover 24. The cylinder 21 is vertically fixed in the mounting frame 11, and the heating part of the heating unit 22 is arranged at the bottom of the cylinder 21 or directly below the cylinder 21. Specifically, the heating unit 22 is a gas or electric heating tube. When the heating unit 22 is gas, the heating part of the heating unit 22 is arranged directly below the cylinder 21. When the heating unit 22 is an electric heating tube, the heating part of the heating unit 22 is arranged at the bottom of the cylinder 21. The heating unit 22 belongs to the prior art and the specific structure is not repeated here.

[0031] The outer cover 23 is fixed in the mounting frame 11 around the opening on the cylinder 21, and a Hall sensor 231 is provided on the outer cover 23. Specifically, the outer cover 23 is a square structure, and the edge of the outer cover 23 and the side wall of the shell 10 are welded to form an integral structure, wherein the uppermost outer cover 23 is 10-15 mm lower than the top surface of the shell 10 to prevent water entering the outer cover 23 from overflowing out of the shell 10. The top surface of the cylinder 21 is sealed with the bottom surface of the outer cover 23, which effectively prevents the soup from overflowing during cooking.

[0032] The supporting cover 24 can be rotatably covered on the upper opening of the cylinder 21, and its outer circumference is fixedly connected to the outer gear ring 241. The supporting cover 24 is provided with at least three evenly distributed placement holes 242, and the placement holes 242 are used to fix the net bag 50. The outer edge of the outer cover 23 is provided with a position identifier 246 corresponding to each placement hole 242, and the position identifier 246 is a magnet.

[0033] like Figure 2 As shown, the placement hole 242 includes a central hole and peripheral holes arranged around the central hole, and the number of the peripheral holes is at least six.

[0034] The driving assembly includes a motor 31 and a driving gear 32. The motor 31 is fixed to the side of the mounting frame 11. Its output shaft passes through the outer cover plate 23 through a sealed bearing and is connected to the driving gear 32. The driving gear 32 is engaged with the outer ring gear 241. The motor 31 drives the driving gear 32 to rotate, and the driving gear 32 rotates and engages to drive the outer ring gear 241 to rotate, so that the peripheral holes farther away from the operator can be rotated to the vicinity of the operator, making it convenient for the operator to take out the net bag 50 from the corresponding placement hole 242 or place the net bag 50 into the corresponding placement hole 242.

[0035] The control device includes a controller and an operation panel 40. The controller is electrically connected to the Hall sensor 231 and the motor 31. By controlling the operation panel 40, based on the feedback signal of the Hall sensor 231 to the position identifier 246, the support cover 24 is controlled to rotate to a preset angle.

[0036] In an embodiment of the present invention, the operation panel 40 also includes a selection button, a time adjustment button, a start button and an end button. The selection button is used for the operator to place the net bag 50 in different placement holes 242. The time adjustment button is used to preset the heating time for the selected placement hole 242. The start button is used to time the selected placement hole 242. The end button is used to stop timing the selected placement hole 242 and feedback a signal to the controller, so that the motor 31 drives the driving gear 32 to rotate, and then the corresponding placement hole 242 rotates to the preset position.

[0037] In an embodiment of the present invention, the control device 40 is arranged on the front side wall of the shell 10, and the two sets of pot body assemblies can share one set of control devices. In other optional embodiments, there can be two sets of control devices 40, and the two sets of pot body assemblies each use one set of control devices independently.

[0038] In the specific use of a commercial cooking stove disclosed in an embodiment of the present invention, when the operator triggers the selection button, the motor 31 starts, driving the outer ring gear 241 and the placement holes 242 provided thereon to rotate, rotating the corresponding numbered vacant placement hole 242 to a preset working position near the operator. At this point, the operator can place the net bag 50 containing the food to be cooked into the placement hole 242 at that working position, then set the target cooking time using the time adjustment button, and press the start button, and the system will immediately start the cooking timer. Repeating the above operation process, the operator can continuously trigger different selection buttons to sequentially place multiple net bags 50 containing food into the corresponding vacant placement holes 242 that have been rotated into position and set the cooking time. After the cooking timer corresponding to any net bag 50 is completed, the operator presses the corresponding end button, and the control system automatically sends a command to the motor drive system, driving the outer ring gear 241 to rotate, transporting the cooked net bag 50 to a food pickup position near the operator for subsequent processing by the operator.

[0039] In an embodiment of the present invention, the drive assembly further includes a driven gear 33, which is rotatably mounted on the outer cover plate 23 via a bearing 34. The driven gear 33 shares the radial load of the driving gear 32 and simultaneously serves as a limiter for the outer cover plate 23 to prevent displacement during rotation of the outer cover plate 23.

[0040] In an embodiment of the present invention, the control device also includes an indicator light and a voice alarm. The signal input ends of the indicator light and the voice alarm are respectively connected to the signal output ends of the controller. When the food in the designated net bag 50 is cooked, the indicator light of the corresponding selection button lights up, and the voice alarm emits a reminder sound. At this time, the operator presses the end button, the voice alarm automatically turns off, and the operator can take out the corresponding net bag 50.

[0041] like Figure 2 and Figure 3 As shown, in an embodiment of the present invention, the bottom surface of the supporting cover plate 24 is provided with a downwardly extending raising ring 243, and a plurality of rollers 244 are spaced apart on the bottom surface of the raising ring 243. A guide ring groove 232 for the rollers 244 to move is provided on the outer cover plate 23. The rollers 244 move in the guide ring groove 232, thereby reducing the friction resistance of the supporting cover plate 24 to rotate.

[0042] In an embodiment of the present invention, the supporting cover plate 24 is provided with a positioning protrusion 245 located beside each placement hole 242, and the outer edge of the net bag 50 is provided with a positioning groove 501 that cooperates with the positioning protrusion 245. The positioning protrusion 245 is preferably a convex column, and the upper end of the convex column is a rounded structure. The positioning groove 501 cooperates with the positioning protrusion 245 to position the net bag 50 to avoid accidental touching of the net bag 50 and causing the net bag 50 to move.

[0043] In an embodiment of the present invention, a faucet 233 for injecting water into the cylinder 21 is provided on the outer cover 23. The water inlet end of the faucet 233 is connected to an external water source. The faucet 233 is provided to facilitate adding water into the cylinder 21. A drain valve is provided at the side bottom of the cylinder 21. After cooking is completed, the noodle soup in the cylinder 21 can be emptied through the drain valve.

[0044] In an embodiment of the present invention, an overflow hole 234 is provided on the outer cover plate 23, and the overflow hole 234 is connected to an external discharge pipe. Specifically, the top surface of the portion of the supporting cover plate 24 where the placement hole 242 is provided is 5mm-20mm lower than the top surface of the outer cover plate 23 to reduce the noodle soup from splashing onto the outer cover plate 23. The overflow hole 234 can allow the noodle soup accidentally splashed onto the outer cover plate 23 to flow out through the overflow port.

[0045] In the embodiment of the present invention, there is a gap between the driving gear 32 and the driven gear 33 and the top surface of the outer cover plate 23 , and the width of the gap is 5mm-10mm. At this time, the driving gear 32 and the driven gear 33 are not in contact with the outer cover plate 23 .

[0046] The commercial cooking stove of this embodiment of the present invention supports the parallel processing of multiple food types without interfering with each other, fundamentally resolving the limitation of the same type of food caused by the single cavity of traditional cooking pots. When processing noodles (rice noodles) and dumplings simultaneously, the multiple independent mesh bag support structures 50, combined with the placement holes 242 arranged in a circular array, enable precise time-slot independent control based on the different cooking time requirements of different noodle types or filling recipes, avoiding overcooking or undercooking caused by mixed cooking.

[0047] The commercial kitchen stove of the embodiment of the present invention can execute independent operation instruction response, timing parameter setting and cooking status feedback for each net bag 50, accurately record the real-time cooking time of each net bag 50, and trigger an alarm instruction when the preset time threshold is reached. Compared with the traditional manual timing method, this automated control solution significantly improves the accuracy and efficiency of multi-tasking, and at the same time increases the feasibility of adding more net bags to the system.

[0048] The commercial kitchen stove of the embodiment of the present invention is provided with a double-layer pot body assembly to further enhance the feasibility of adding a net bag.

[0049] The technical solution of the present invention has been described in detail above with reference to specific embodiments. The specific embodiments described are intended to help understand the concept of the present invention. Derivations and modifications made by those skilled in the art based on the specific embodiments of the present invention also fall within the scope of protection of the present invention.
