Description

Technical Field

[0001] This application relates to the field of cooking machines, and more specifically, to a liquid seasoning dispensing device. Background Technology

[0002] With the rapid development of restaurant chains and central kitchens, stir-fry equipment is gradually evolving towards automation and standardization. To improve product consistency and reduce reliance on manual labor, equipment is typically equipped with automatic metering and dispensing systems for liquid seasonings (such as soy sauce, cooking wine, vinegar, diluted oyster sauce, compound sauces, and oil-based seasonings). In existing technologies, automatic liquid seasoning dispensing generally includes a liquid seasoning storage container, a metering / transfer pump, delivery pipelines, and a dispensing port or spray assembly located above the stir-fry pan. The seasonings are pumped into the pan to complete the addition process.

[0003] However, stir-frying conditions are characterized by high temperature, high humidity, strong oil fumes, and strong disturbances: steam and oil fumes easily rise from the pot, and the stir-frying process is accompanied by airflow pulsation and splashing droplets. Many existing feeding structures use a fixed, continuous feeding / drainage port design, meaning the feeding port remains connected to the pot opening area for extended periods, or relies solely on simple check valves, hose dangling, or gravity dripping for "passive isolation." In practical use, these structures often have the following problems: When the inlet is continuously connected to the internal space of the pot, steam, fumes and tiny oil droplets inside the pot can easily enter the inlet, interface cavity or end area of ​​the pipeline along the channel, causing oil stains to adhere to the interface, odor residue, or even enter the pump body or upstream pipeline, bringing hygiene risks and cross-contamination hazards. Summary of the Invention

[0006] Furthermore, the liquid seasoning storage structure includes multiple liquid seasoning boxes; the interface plate is provided with multiple connection interfaces; the liquid delivery pipeline has multiple connection pipelines connecting any liquid seasoning box and any connection interface; the pump body structure is disposed on the connection pipeline and is used to extract the liquid seasoning from the liquid seasoning box to the connection interface.

[0007] Furthermore, the liquid seasoning adding device also includes: a silicone sleeve disposed at the end of the connecting pipe and a one-way structure disposed on the silicone sleeve; the silicone sleeve is fixed to the end of the connecting pipe, and the diameter of the silicone sleeve is larger than the diameter of the connecting interface; the one-way structure constructs a channel for the liquid to flow from the connecting pipe to the connecting interface and blocks the channel for the liquid to flow back into the connecting pipe from the connecting port.

[0008] Furthermore, the connection interface is provided with a first slot and a second slot, the diameter of the first slot being smaller than the diameter of the second slot; the silicone sleeve is sequentially inserted into the first slot and the second slot; the rubber sleeve has a first locking part and a second locking part, the diameter of the first locking part being the diameter of the second locking part, the first locking part being located in the first slot, and the second locking part being located in the second slot.

[0009] Furthermore, the unidirectional structure includes two silicone valve pieces that abut against each other inside the silicone sleeve; the end of the liquid delivery pipe is closed and has a liquid outlet micro-hole, so that the liquid seasoning can only be discharged by pushing open the silicone valve pieces in a direction away from the liquid delivery pipe.

[0010] Furthermore, the plurality of liquid seasoning boxes include at least a first seasoning box, a second seasoning box, and a third seasoning box; the first seasoning box is used to store a first seasoning with high fluidity, the second seasoning box is used to store a second seasoning with poor fluidity or containing particles, and the third seasoning box is used to store a third seasoning that is prone to solidification; the plurality of connecting pipes include at least a first pipe corresponding to the first seasoning box, a second pipe corresponding to the second seasoning box, and a third pipe corresponding to the third seasoning box; the first pipe has a pump body structure and a plurality of first drain ports; and / or the second pipe has two pump body structures and a second drain port; and / or the third pipe has one or two pump body structures and a third drain port.

[0011] Furthermore, both the second and third seasoning boxes are equipped with a stirring structure.

[0012] Furthermore, the first seasoning box is located above the second seasoning box and the third seasoning box.

[0015] The beneficial effects of this application are as follows: The interface plate is switched between "inside the channel" and "outside the channel" by a rotating drive structure, so that the seasoning inlet and the channel can be selectively connected or isolated: in the dispensing state, a clear flow path is formed, and the liquid seasoning can fall stably into the frying pot; in the isolation state, the connection between the pot and the interface area is cut off, reducing the probability of steam rising, oil fume backflow and splashing into the interface area, thus reducing pollution and scaling from the source.

[0016] When the interface plate is in the isolated position outside the through groove, the baffle blocks the seasoning inlet, which can reduce the entry of oil fumes, steam and condensate into the area around the interface and reduce the risk of bacterial growth caused by oil accumulation. When in the isolation position, the connection interface faces downward and the liquid delivery pipeline is connected to the upper part of the interface plate, making it easier for residual liquid at the connection interface to drip off under gravity, reducing residue on the wall; at the same time, it reduces the possibility of residual liquid flowing back along the pipeline direction, and the unidirectional structure can further suppress backflow and odor.

[0024] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0025] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Reference Figure 1-7 , This embodiment provides a liquid seasoning adding device, which can be applied in a cooking machine to quantitatively or periodically deliver and add liquid seasoning into the cooking pot 11.

[0027] As shown in the figure, the liquid seasoning addition device includes a liquid seasoning storage structure 2, a pump body structure 3, a liquid delivery pipeline 22, and a dispensing component 4. The liquid delivery pipeline 22 connects the liquid seasoning storage structure 2 and the pump body structure 3 in sequence, allowing the liquid seasoning to be transported along the flow path of "liquid seasoning storage structure 2 → liquid delivery pipeline 22 → pump body structure 3 → liquid delivery pipeline 22 outlet". The liquid delivery pipeline 22 outlet is connected to the dispensing component 4, and the liquid seasoning is finally dispensed into the frying pan 11 via the dispensing component 4.

[0028] The dispensing component 4 is positioned above the frying pan body 11. The dispensing component 4 includes a mounting shell 41, an interface plate 42, and a rotary drive structure 43. A through groove 411 is formed within the mounting shell 41, which mates with the opening 111 of the frying pan body 11, allowing liquid seasonings discharged through the dispensing component 4 to fall into the frying pan body 11. A seasoning inlet 412 is provided on the side of the mounting shell 41, and the interface plate 42 is positioned at the seasoning inlet 412.

[0029] The rotary drive structure 43 is used to drive the interface plate 42 to switch between "interface plate 42 is inside the through groove 411" and "interface plate 42 is outside the through groove 411" to achieve selective connection or isolation of the seasoning inlet 412 and orderly guide and dispense liquid seasoning.

[0030] In one alternative implementation, the rotary drive structure 43 includes a first motor 431, a reduction mechanism 432, and a transmission connector 433, which may be, for example, a coupling. The first motor 431 drives the interface plate 42 to rotate or swing through the reduction mechanism 432 and the transmission connector 433, thereby switching the interface plate 42 between a position where "the interface plate 42 is inside the through slot 411" and a position where "the interface plate 42 is outside the through slot 411".

[0031] The switching position of interface board 42 can correspond to at least two states: First state: The interface plate 42 extends into the through groove 411, so that the seasoning inlet 412 and the through groove 411 form a flowable delivery path, and the liquid seasoning can enter the frying pot body 11 through the seasoning inlet 412 and the through groove 411. Second state: The interface plate 42 is removed from the through groove 411, which isolates the seasoning inlet 412 from the through groove 411, thereby reducing the probability of steam rising, oil fume recirculation or splashing into the interface area.

[0032] It should be noted that the phrase "interface plate 42 is located inside or outside the through groove 411" in this embodiment is not limited to the interface plate 42 being completely inside or outside the through groove 411. It can also be that the interface plate 42 is partially inside or partially outside the through groove 411, as long as the opening and closing of the seasoning delivery path can be achieved.

[0033] The liquid seasoning storage structure 2 includes multiple liquid seasoning containers 21. The interface plate 42 has multiple connection interfaces 421. The liquid delivery pipeline 22 has multiple connection lines, which connect any liquid seasoning container 21 to any connection interface 421, thus forming an extended structure of "multiple seasoning containers – multiple connection interfaces 421" to meet the needs of different recipes for various liquid seasonings. Liquid seasonings may include soy sauce, cooking wine, oyster sauce, compound sauces, etc.

[0034] Pump body structure 3 is installed on the connecting pipeline and is used to extract liquid seasonings from liquid seasoning box 21 and transport them to the corresponding connecting interface 421. Pump body structure 3 can be a peristaltic pump, diaphragm pump, or gear pump. For seasonings with high fluidity, a peristaltic pump is preferred for hygiene and maintenance; for seasonings with high viscosity or containing particles, a diaphragm pump with a larger diameter or a reinforced peristaltic pump can be selected, and the conveying stability can be improved by controlling the speed or duty cycle.

[0035] In one embodiment, each connecting pipeline can be configured with a corresponding pump body structure 3 to achieve independent quantitative control. In another embodiment, multiple connecting pipelines can also share the pump body structure 3 and be distributed through a valve assembly.

[0036] The liquid seasoning dispensing device also includes a silicone sleeve disposed at the end of the connecting pipe and a one-way structure disposed on the silicone sleeve. The silicone sleeve is fixed to the end of the connecting pipe, and the diameter of the silicone sleeve is larger than the diameter of the connecting interface 421 to achieve plug-in sealing and assembly tolerance compensation. The one-way structure creates a channel for the liquid to flow from the connecting pipe to the connecting interface 421 and blocks the channel for backflow from the connecting interface 421 into the connecting pipe.

[0037] This unidirectional structure reduces the risk of steam, fumes, or condensate flowing back into the connecting pipes along the dispensing path; it also reduces the risk of cross-contamination or flavor mixing between different seasonings due to pressure disturbances; and it reduces backflow during pump shutdown, minimizing problems such as unstable dripping or increased metering errors.

[0038] The connection interface 421 has a first slot and a second slot, with the diameter of the first slot being smaller than that of the second slot. A silicone sleeve is sequentially inserted into the first and second slots to form a stepped positioning and seal. The silicone sleeve has a first locking part and a second locking part, with the diameters of the first and second locking parts being different. The first locking part is located in the first slot, and the second locking part is located in the second slot. This structure provides a clear limit and tactile feedback when the silicone sleeve is properly inserted, preventing leakage due to insufficient insertion. It also forms a double seal, improving pressure resistance and vibration resistance, and facilitating quick disassembly and assembly, thus simplifying spice box replacement, cleaning, maintenance, or after-sales repair.

[0039] The unidirectional structure includes two silicone valve plates that are disposed inside a silicone sleeve and abut against each other. The end of the liquid delivery pipe is sealed and has a liquid outlet micro-hole 221, so that the liquid seasoning can only be discharged by pushing open the silicone valve plates in the direction away from the liquid delivery pipe.

[0040] During operation, when the output pressure of pump body structure 3 increases, the liquid seasoning forms a jet or local pressure difference through the outlet micro-hole 221, opening the two silicone valve plates and discharging into the connection interface 421. When pump body structure 3 stops or the pressure drops, the two silicone valve plates rebound under their own elasticity and the action of external pressure difference, and abut against each other, sealing the backflow channel, thereby achieving backflow prevention and anti-drip. The outlet micro-hole 221 can also improve the flow interruption effect of high-viscosity seasonings and reduce tail drips.

[0041] The plurality of liquid seasoning containers 21 include at least a first seasoning container, a second seasoning container, and a third seasoning container. The first seasoning container is used to store a first seasoning with high fluidity, such as soy sauce, cooking wine, or vinegar; the second seasoning container is used to store a second seasoning with poor fluidity or containing particles, such as chili oil; and the third seasoning container is used to store a third seasoning that is prone to solidification, such as starch water.

[0042] Correspondingly, the multiple connecting pipes include at least a first pipe, a second pipe, and a third pipe, which are respectively connected to the first seasoning box, the second seasoning box, and the third seasoning box.

[0043] In one embodiment, the first pipeline has a pump body structure 3 and multiple first drain ports. The multiple first drain ports can correspond to different connection interfaces 421 or different dispensing positions to achieve the distribution of the same flowable material to different frying pans 11 or different dispensing points, thereby reducing the number of pump body structures 3 and improving supply flexibility.

[0044] In one embodiment, the second pipeline has two pump body structures 3 and a second drain port. The two pump body structures 3 can be used for series pressurization or parallel flow enhancement to improve the conveying stability of high-viscosity or particulate-containing seasonings and reduce the risk of clogging.

[0045] In one embodiment, the third pipeline has one or two pump body structures 3 and a third drain port. For easily solidified seasonings, a single-pump or dual-pump solution can be selected based on the actual viscosity and temperature sensitivity. The single-pump solution can meet the requirements of flowable conditions at room temperature, while the dual-pump solution can be used for initial delivery in low-temperature, high-viscosity conditions or after long periods of standing.

[0046] The structure of the first, second, and third pipelines can be flexibly combined according to product positioning, seasoning type, and pump specifications, and it is not required that all three be present at the same time.

[0047] Both the second and third seasoning boxes are equipped with a stirring structure 7. The stirring structure 7 may include a stirring paddle, a stirring shaft, and a driving component, which may be a micro motor or a magnetically coupled drive. By periodically or on demand stirring, the risk of particle sedimentation, phase separation, or consolidation can be reduced, and the uniformity and metering consistency of the feed at the suction end of the pump body structure 3 can be improved.

[0048] In one alternative, the stirring structure 7 can be linked with the pump body structure 3. For example, before the pump body structure 3 is started, the stirring structure 7 pre-stirs for a preset time; during the operation of the pump body structure 3, the stirring structure 7 continuously stirs at a low speed; after the pump body structure 3 stops, the stirring structure 7 briefly reverses the stirring to reduce the adhesion of seasonings.

[0049] In one embodiment, the first condiment box is located above the second and third condiment boxes. This arrangement facilitates placing more frequently replenished or more volatile, flow-oriented condiments in the more easily accessible upper section.

[0050] The dispensing component 4 is installed above the frying pot body 11, so that the through groove 411 of the mounting shell 41 is connected to the opening 111 of the frying pot body 11. The interface plate 42 is set at the seasoning inlet 412 on the side of the mounting shell 41. Multiple connection interfaces 421 are arranged on the interface plate 42, and the connection interfaces 421 are detachably plugged into the ends of each connection pipe.

[0051] During operation, the rotary drive structure 43 drives the interface plate 42 to switch to the placement position where "interface plate 42 is located inside the through groove 411," forming a flow path between the seasoning inlet 412 and the through groove 411. The corresponding pump structure 3 starts, transporting the liquid seasoning through the connecting pipe to the connecting interface 421, and then through the one-way structure into the dispensing component 4, finally falling into the frying pot body 11. After dispensing, the pump structure 3 stops, and the interface plate 42 switches to the isolation position where "interface plate 42 is located outside the through groove 411," reducing the entry of steam and fumes into the seasoning inlet 412 area, thus reducing scaling and odor transfer.

[0052] In one alternative implementation, the interface board 42 can be configured with multiple angular positions. These multiple angular positions can correspond to the conduction state of different connection interfaces 421 aligned with the seasoning inlet 412, or to the dispensing direction of different openings 111 of the frying pan body 11. The rotary drive structure 43 can provide feedback on the current position of the interface board 42 via a position sensor, such as a Hall effect sensor, photoelectric encoder, or limit switch, to ensure accurate dispensing.

[0053] This embodiment also provides a stir-fry machine. The stir-fry machine includes a body 1, a wok body 11, and the aforementioned liquid seasoning adding device. The wok body 11 is disposed on the body 1 and is used to hold the ingredients and heat and stir-fry them. The liquid seasoning adding device is disposed on the body 1 and is used to quantitatively or periodically deliver liquid seasoning to the top of the wok body 11 and add it into the wok body 11.

[0054] In one embodiment, the machine body 1 forms a first accommodating space 12 between the two frying pans 11, and a second accommodating space 13 below the two frying pans 11. Liquid seasoning storage structures 2 can be distributed within the first accommodating space 12 and the second accommodating space 13 to achieve a compact structure, stable center of gravity, and partitioned arrangement of seasoning containers. For example, the first accommodating space 12 can house a first seasoning container for easy addition and replacement by the user; the second accommodating space 13 can house a second seasoning container, a third seasoning container, and a stirring structure 7, utilizing the lower space to accommodate heavier components and lower the overall center of gravity of the machine.

[0055] The liquid seasoning addition device in this embodiment can be applied to both single-pot and multi-pot structures. For a double-pot structure, the dispensing component 4 can be connected to the opening 111 of either the first or second frying pot 11, or it can be configured to connect to both, to meet the usage scenarios of cooking different dishes in parallel or alternately.

[0056] In some embodiments, a baffle 5 is further provided on the interface plate 42, and the baffle 5 is arranged perpendicularly to the interface plate 42. The baffle 5 may be an integrally formed structure, such as being integrally formed by injection molding or sheet metal bending with the interface plate 42; the baffle 5 may also be a separate structure and fixed to the interface plate 42 by screws, riveting or buckles.

[0057] In this embodiment, the rotary drive structure 43 is used to drive the interface plate 42 to switch between a first position and a second position. The first position is when the interface plate 42 is located inside the through groove 411, so that the seasoning inlet 412 and the through groove 411 form a communication path, which facilitates the liquid seasoning to enter the through groove 411 through the connection interface 421 and fall into the frying pot body 11; the second position is when the interface plate 42 rotates to the outside of the through groove 411, so that the interface plate 42 is removed from the dispensing area of ​​the through groove 411.

[0058] When the interface plate 42 is rotated to the second position, the baffle 5 is located at the seasoning inlet 412 and blocks the seasoning inlet 412, thereby reducing the probability of oil fumes, steam or splashes entering the mounting shell 41, and thus reducing the risk of oil stains adhering and contaminating the connection interface 421 and its surrounding area.

[0059] When the interface plate 42 is rotated to the second position, the connection interface 421 on the interface plate 42 is positioned downwards, and the liquid delivery pipeline 22 is connected to the upper part of the interface plate 42. This arrangement allows residual liquid at the connection interface 421 to drip more easily under gravity, reducing residue; it also reduces the possibility of residual liquid flowing back along the liquid delivery pipeline 22, thereby improving hygiene and reliability.

[0060] In some embodiments, a receiving hopper 8 is provided on the mounting housing 41, and the receiving hopper 8 is located outside the seasoning inlet 412. The receiving hopper 8 can be fixedly disposed on the outside of the mounting housing 41, for example by fixing with screws, welding or snap fasteners; the receiving hopper 8 can also be integrally formed with the mounting housing 41.

[0061] When the interface plate 42 is located outside the seasoning inlet 412, for example, when the interface plate 42 is in the second position, the receiving hopper 8 is located directly below the interface plate 42. Thus, when the connection interface 421 faces downward and residual liquid drips, the residual liquid can be collected by the receiving hopper 8, realizing residual liquid collection and preventing residual liquid from dripping directly onto the outside of the equipment or the work surface, thereby improving cleanliness and safety.

[0062] Optionally, the receiving hopper 8 may be equipped with a guide surface or a guide channel to allow the collected residual liquid to converge at a preset location for centralized recycling or discharge. The receiving hopper 8 may also be configured as a detachable structure, such as a pull-out structure or a snap-on structure, to facilitate regular cleaning and maintenance.

[0063] The baffle 5 blocks the seasoning inlet 412, reducing the probability of oil fumes entering the mounting housing 41 and decreasing oil buildup at the connection interface 421, thereby improving hygiene and reliability. The receiving hopper 8 collects and recycles residual liquid, preventing spillage and improving the ease of cleaning and maintenance. The reciprocating movement and rotation of the movable frame 6 allow for multi-angle cleaning of the connection interface 421 and residual liquid recovery even when not cleaning, balancing cleaning efficiency and recovery effectiveness.

[0064] The working process of the liquid seasoning addition device in this embodiment is as follows.

[0065] Preparation stage: Under the drive of the rotary drive structure 43, the interface plate 42 is located outside the through groove 411. The baffle 5 blocks the seasoning inlet 412, the connection interface 421 faces downward, and the receiving hopper 8 is located below the interface plate 42 to collect any dripping residual liquid. Each pump body structure 3 is in a stopped state, and the one-way structure is in a closed or naturally fitted state to suppress backflow and backflow.

[0066] Dispensing Phase: The rotary drive structure 43 drives the interface plate 42 to switch to the first position, positioning the interface plate 42 within the through groove 411. The seasoning inlet 412 and the through groove 411 form a flow path for dispensing. The pump structure 3 starts, conveying the liquid seasoning along the flow path of "liquid seasoning box 21 → connecting pipeline → pump structure 3 → connecting pipeline → connecting interface 421". Under pressure, the liquid seasoning pushes open the silicone valve plate, enters the connecting interface 421, and is guided by the dispensing component 4 into the frying pan 11. For multi-seasoning box scenarios, different pump structures 3 can be started sequentially to achieve timed or quantitative dispensing of various seasonings. After reaching the set dispensing amount, the pump structure 3 stops, and the unidirectional structure rebounds and closes under the action of elasticity and pressure difference to suppress tail dripping and back suction.

[0067] Isolation and Residual Liquid Recovery Stage: After the addition is completed, the rotary drive structure 43 drives the interface plate 42 to return to the second state. At this time, the baffle 5 blocks the seasoning inlet 412 to reduce the entry of oil fumes and steam into the interface area; the connection interface 421 faces downward, and the residual liquid drips down under the action of gravity and drips into the receiving hopper 8 for collection and recovery, avoiding external dripping pollution.
