Description

Technical Field

[0001] The invention relates to the field of cooking machines, and in particular to a multi-channel liquid seasoning discharging mechanism and a cooking machine. Background Art

[0002] The liquid seasoning of the existing cooking machine is manually added or pumped. When manually added, a built-in scale is used to weigh the liquid seasoning to determine the weight. When pumped, each liquid seasoning is extracted by a water pump, or one water pump extracts different liquid seasonings through a reversing valve.

[0003] For the manual feeding solution, the amount cannot be accurately controlled or a lot of time is wasted during the process of manually feeding the seasoning due to the limited accuracy of human hands.

[0004] For using a water pump to extract different liquid seasonings through a reversing valve, when the pump body extracts liquid seasonings, if each liquid seasoning uses a water pump, the cost is high, the control is more complicated, and the error rate is high. Using a water pump to extract different liquids through a reversing valve, the cost of the reversing valve will increase as the number of liquid seasonings increases, and a water pump extracting different liquids will cause mixing, affecting the cooking experience. In addition, liquid seasonings will remain in the pipeline for a long time, especially liquid seasonings containing impurities such as soy sauce, which will be deposited in the pipeline and blocked. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the problems in the prior art of low precision and long time consumption of manual feeding, easy mixing of materials in the scheme of using a single water pump to transfer multiple seasonings by reversing, and high cost of the scheme of calling a water pump for each seasoning, and to provide a multi-channel liquid seasoning discharging mechanism and a cooking machine.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] A multi-channel liquid seasoning discharge mechanism comprises a multi-channel pumping and charging switching device and a plurality of discharge chambers, wherein the discharge chamber comprises a accommodating chamber and a liquid outlet passage connecting the accommodating chamber with the outside, the accommodating chamber comprises a liquid accommodating area connected to the liquid outlet passage and an air pressure chamber located above the liquid accommodating area, wherein at least a portion of the liquid outlet passage is higher than the liquid accommodating area, the multi-channel pumping and charging switching device comprises a branch pipe connecting a plurality of the air pressure chambers, a switching module and a control module, wherein the control module is used to receive cooking information and control the switching module to execute the shut-off and on operations of the branch pipes and the pumping and charging switching operations of the branch pipes.

[0008] The solution of the present invention has the following advantages. First, multiple seasoning chambers are centrally controlled by a multi-way pumping and charging switching device. Compared with the solution of separately setting a water pump in each seasoning chamber, it has fewer control components and effectively reduces the cost. Compared with the solution of using a water pump to extract multiple seasonings separately through a reversing valve, the multi-way pumping and charging switching device in the present invention does not directly contact the seasoning, and there is no problem of mixing. Secondly, the present invention adopts a gas circuit switching control mode, and no liquid will be left in the control pipeline, so there is no problem of blockage due to drying of the seasoning. It has higher reliability in use and longer service life.

[0009] Preferably, the liquid outlet passage is a siphon passage, and the liquid outlet passage has a siphon opening higher than the liquid containing area. When the branch pipe inflates the air pressure chamber until the liquid seasoning runs in the liquid outlet passage to a position beyond the siphon opening, the liquid outlet passage generates a siphon effect, so that the liquid seasoning can flow out continuously and uninterruptedly under the action of the siphon effect. Since the siphon effect has a stable flow rate, this method can better control the amount of material discharged and improve the accuracy of material discharge.

[0010] Preferably, the cooking information includes material feeding start information, and after receiving the material feeding start information, the control module controls the switching module to inflate the branch pipe until the liquid outlet passage produces a siphon effect, and then shuts off the branch pipe.

After receiving the information on the completion of feeding, the control module controls the switching module to cause the branch pipe to evacuate air until the siphon effect of the liquid outlet passage stops, and then shuts off the branch pipe.

[0012] Preferably, the cooking information includes material quantity information, and the material quantity information is the time difference between the material loading start information and the material loading end information.

[0013] The above-mentioned liquid seasoning feeding start and stop and feeding amount control logic has the following advantages: since the volume of the liquid outlet passage is small, only a small amount of pumping and inflation is required to realize the start and release of the siphon effect of the liquid outlet passage, so it has the advantage of fast response speed. In addition, after the feeding starts and between receiving the feeding stop information, the switching module is in an idle state, and at this time, the switching module can be controlled to perform the feeding operation of another seasoning, which makes it possible to operate multiple containing chambers to feed seasonings at the same time. There is no need to wait for one of the seasonings to be fed before performing the feeding operation of another seasoning, so that the feeding timing can be better grasped and the cooking effect can be improved.

[0017] Since the first switching mechanism and the second switching mechanism are operated synchronously, only one action mechanism is needed to drive them. Compared with the first switching mechanism and the second switching mechanism performing switching operations separately, this solution significantly reduces the cost. At the same time, the control logic is simplified, and the development is simpler.

[0089] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0090] Example 1

[0091] like Figure 1 , Fig. 9 and Fig.16As shown, this embodiment provides a multi-channel liquid seasoning discharge mechanism, which includes a multi-channel pumping and charging switching device 10 and a plurality of discharge chambers 20, wherein the discharge chamber 20 includes a receiving chamber 600 for placing liquid seasoning and a liquid outlet passage 630 connecting the receiving chamber 600 with the outside. Specifically, the receiving chamber 600 is a closed structure, including a liquid receiving area 620 connected to the liquid outlet passage 630 and a gas pressure chamber 610 located above the liquid receiving area 620, and the liquid outlet passage 630 is at least partially higher than the liquid receiving area 620 to prevent the liquid seasoning in the liquid receiving area 620 from overflowing from the liquid outlet passage 630 due to the U-tube effect. The air pressure chamber 610 is relatively isolated from the external environment by the liquid seasoning located in the liquid containing area 620. When the air pressure in the air pressure chamber 610 changes, the volume of the air pressure chamber 610 can expand or shrink, thereby squeezing out or retracting the liquid seasoning in the liquid containing area 620 from the liquid outlet passage 630.

[0092] Combination Figure 2 , Fig.14 The multi-way pumping and charging switching device 10 includes a branch pipe 100, a switching module 400 and a control module 500, which are respectively connected to the air pressure chambers 610 in multiple discharge chambers 20. The control module 500 can be used to receive cooking information and control the switching module 400 to perform the shut-off and on operations of the branch pipe 100 and the pumping and charging switching operations of the branch pipe 100.

[0093] When one of the accommodating chambers 600 is required to discharge the seasoning, the switching module 400 shuts off the branch pipes 100 connected to the other accommodating chambers 600 and connects the branch pipes 100 connected to the accommodating chamber 600. The branch pipes 100 are then controlled to inflate the air pressure chamber 610 of the accommodating chamber 600, and the volume of the air pressure chamber 610 increases, squeezing the seasoning in the liquid accommodating area 620 out of the liquid outlet passage 630.

[0094] When the accommodating chamber 600 needs to stop discharging materials, the branch pipe 100 is controlled to switch from the inflation state to the exhaust state. At this time, the volume of the air pressure chamber 610 is reduced, and the liquid in the liquid outlet passage 630 can be drawn back from the liquid containing area 620, thereby stopping the discharge of seasoning.

[0095] The solution of the present invention has the following advantages. First, multiple seasoning chambers are centrally controlled by a multi-way pumping and charging switching device 10. Compared with the solution of separately setting a water pump in each seasoning chamber, it has fewer control components and effectively reduces the cost. Compared with the solution of using a water pump to extract multiple seasonings separately through a reversing valve, the multi-way pumping and charging switching device 10 in the present invention does not directly contact the seasoning, and there is no problem of mixing. Secondly, the present invention adopts a gas circuit switching control mode, and no liquid will be left in the control pipeline, so there is no problem of blockage due to drying of the seasoning. It has higher reliability in use and longer service life.

[0096] In this embodiment, the liquid outlet passage 630 is a siphon passage, and the liquid outlet passage 630 has a siphon port 631 higher than the liquid containing area 620. The siphon port 631 referred to here refers to the node position where the liquid outlet passage 630 generates a siphon force on the liquid in the containing chamber 600 when the liquid outlet passage 630 is in a siphon state. In the present invention, the siphon port 631 is at the highest point in the liquid outlet passage 630. When the branch pipe 100 inflates the air pressure chamber 610 until the liquid seasoning runs in the liquid outlet passage 630 to a position that exceeds the siphon port 631, the liquid outlet passage 630 generates a siphon effect, so that the liquid seasoning can continue to flow out uninterruptedly under the action of the siphon effect. Since the siphon effect has a stable flow rate, this method can better control the amount of material discharged and improve the accuracy of material discharge.

[0097] For the solution in which the liquid outlet passage 630 is a siphon passage, the control logic of material discharge is as follows: the cooking information transmitted to the control module 500 includes material discharge start information. After receiving the material discharge start information, the control module 500 controls the switching module 400 to inflate the branch pipe 100 until the liquid outlet passage 630 produces a siphon effect, and then shuts off the branch pipe 100.

[0098] The node position for causing the liquid outlet passage 630 to produce a siphon effect is the position where the liquid seasoning passes over the siphon port 631 of the liquid outlet passage 630, where the liquid can flow from the siphon port 631 to the outlet under the action of gravity, thereby driving the siphon effect to continue uninterruptedly. The specific inflation time for controlling the liquid outlet passage 630 to produce a siphon effect can be calculated through multiple tests, or can be obtained through theoretical calculation based on the volume of the liquid outlet passage 630 and the gas flow rate of the multi-way pumping and inflation switching device 10.

[0099] For the solution in which the liquid outlet passage 630 is a siphon passage, the control logic for stopping material discharge is as follows: the information transmitted to the control module 500 includes material discharge completion information. After receiving the material discharge completion information, the control module 500 controls the switching module 400 to evacuate the branch pipe 100 until the siphon effect of the liquid outlet passage 630 stops, and then shuts off the branch pipe 100.

[0100] The node position for causing the liquid outlet passage 630 to produce a siphon effect is the position where the liquid seasoning flows back to the siphon port 631 beyond the liquid outlet passage 630, where the liquid can fall from the siphon port 631 to the position flush with the liquid seasoning in the liquid containing area 620 under the action of gravity, thereby terminating the siphon effect. The specific air extraction time for controlling the liquid outlet passage 630 to produce a siphon effect can be calculated through multiple tests, or can be obtained through theoretical calculation based on the volume of the liquid outlet passage 630 and the gas flow rate of the multi-way air extraction and charging switching device 10.

[0101] For the solution in which the liquid outlet passage 630 is a siphon passage, the control logic for the amount of seasoning added is as follows: the cooking information includes the amount of added information, and the amount of added information is the time difference between the start information of added and the end information of added. Since the flow rate in the siphon state is constant, the amount of added can be controlled by controlling the time of added.

[0102] The above-mentioned liquid seasoning feeding start and stop and feeding amount control logic has the following advantages: since the volume of the liquid outlet passage 630 is small, only a small amount of pumping and inflation is required to realize the start and release of the siphon effect of the liquid outlet passage 630, so it has the advantage of fast response speed. In addition, after the feeding starts and between receiving the feeding stop information, the switching module 400 is in an idle state, and at this time, the switching module 400 can be controlled to perform the feeding operation of another seasoning, which makes it possible to operate multiple accommodating chambers 600 to feed seasonings at the same time. There is no need to wait for one of the seasonings to be fed before performing the feeding operation of another seasoning, so that the feeding timing can be better grasped and the cooking effect can be improved.

[0103] In this embodiment, the switching control corresponding to the seasoning selection is realized by the following control logic: the cooking information includes the seasoning selection information, and the control module 500 controls the branch pipe 100 corresponding to the branch pipe 100 extending into the seasoning receiving chamber 600 to perform the pumping and charging operation after receiving the seasoning selection information, thereby controlling the loading and unloading of the seasoning.

[0104] like Fig. 9 As shown, in the present embodiment, the branch pipe 100 is connected to the air pressure chamber 610 in the following manner: an air intake passage 640 for connecting the branch pipe 100 is also provided in the accommodating chamber 600, and the air intake passage 640 is used to connect the inlet of the branch pipe 100 and is located at the bottom of the side wall of the accommodating chamber 600, and the main body of the air intake passage 640 passes through the liquid containing area 620 in the accommodating chamber 600 and extends upward to the air pressure chamber 610.

[0105] Since the inlet of the air inlet passage 640 is not located on the top wall of the accommodating chamber 600, the overall height of the cooking machine is reduced, thereby reducing the volume of the entire cooking machine. On the other hand, when adding liquid to the accommodating chamber 600, there will be no collision with the air inlet passage 640, making the adding operation more convenient.

[0106] Furthermore, the air intake passage 640 is arranged to enter from the bottom of the side wall of the accommodating cavity 600 for the following considerations: since the accommodating cavity 600 needs to put seasonings into the cooking pot, it must be at a higher position in the entire cooking machine. Setting the access position of the air intake passage 640 at the bottom of the side wall of the accommodating cavity 600 can reduce the length of the branch pipe 100 connecting the air intake passage 640, facilitate layout, and reduce the probability of equipment failure due to leakage or twisting and entanglement of the external air pipe.

[0107] Furthermore, the air inlet passage 640 includes an outlet section 641 extending along the top of the air pressure chamber 610, and the outlet of the air inlet passage 640 is connected to the outlet section 641. A baffle 642 extending vertically upward and semi-shielding the outlet is also provided at the outlet of the air inlet passage 640.

[0108] Such a structure can keep the outlet of the air intake passage 640 away from the liquid surface, thus preventing liquid from entering the air intake passage 640 and causing failures, while the baffle 642 can further block splashing seasoning from entering the air intake passage 640, further reducing the failure rate.

[0109] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the multi-way pumping and charging switching device 10 includes a pumping pipe 200 and a charging pipe 300 connected to a plurality of branch pipes 100 through a multi-way valve, and the switching module 400 includes a first switching mechanism 410 for selecting and connecting the branch pipes 100 and a second switching mechanism 420 for controlling the pumping pipe 200 and the charging pipe 300 to switch and connect with the branch pipe 100. In this way, the selective connection of multiple branches and the switching of the branch pipe 100 in the pumping and charging state can be realized.

[0110] In this embodiment, the first switching mechanism 410 and the second switching mechanism 420 operate synchronously, and the operation trajectory of the first switching mechanism 410 passes through multiple conduction positions, each of which can conduct one of the multiple branch pipes 100. The operation trajectory of the second switching mechanism 420 passes through a first travel area 421 that can conduct the exhaust pipe 200 and a second travel area 422 that can conduct the inflation pipe 300. Each conduction position includes a first conduction position 411 and a second conduction position 412. When the second switching mechanism 420 synchronously follows the first switching mechanism 410 to run from the first conduction position 411 to the second conduction position 412, the second switching mechanism 420 runs through the boundary between the first travel area 421 and the second travel area 422.

[0111] Thus, the first switching mechanism 410 has a plurality of first conducting positions 411 corresponding to the plurality of branch pipes 100, and a plurality of second conducting positions 412 corresponding to the plurality of branch pipes 100. In this way, each branch pipe 100 can be conducted at two different relative positions of the first switching mechanism 410, namely the first position and the second position, so that the selective conduction of the branch pipe 100 can be achieved.

[0112] During operation, the first switching mechanism 410 moves from the first conducting position 411 to the second conducting position 412, and the second switching mechanism switches from the first travel area 421 to the second travel area 422, so that the branch pipe 100 switches from the exhaust state to the inflation state, thereby realizing the switching of the branch pipe 100 between the exhaust state and the inflation state.

[0113] Since the first switching mechanism 410 and the second switching mechanism 420 are operated synchronously, only one action mechanism is needed to drive them. Compared with the first switching mechanism 410 and the second switching mechanism 420 performing switching operations separately, this solution significantly reduces the cost. At the same time, the control logic is simplified, and the development is simpler.

[0114] like Figure 3 , Figure 5 as well as Figure 7 As shown, in this embodiment, the first switching mechanism 410 includes a first turntable 413, and the branch pipe 100 is arranged at the outer edge of the first turntable 413. The running trajectory of the first switching mechanism 410 is the trajectory formed by any point on the outer edge of the first turntable 413 when the first turntable 413 rotates one circle.

[0115] like Figure 4 , Figure 6 and Figure 8As shown, the second switching mechanism 420 includes a second turntable 423, the exhaust pipe 200 and the inflation pipe 300 are arranged at the outer edge of the second turntable 423, the first turntable 413 and the second turntable 423 are connected to the same drive motor 417 to achieve synchronous rotation, and the trajectory of the second switching mechanism 420 is the trajectory formed by any point on the outer edge of the second turntable 423 rotating around the second turntable 423 for one circle, and the control module 500 is connected to the drive motor 417 to realize the control of the branch pipe 100 selection conduction and the exhaust and inflation switching.

[0116] like Figure 3 , Figure 5 and Figure 7 As shown, in this embodiment, the first switching mechanism 410 also includes a first placement area 414 arranged on the outer peripheral side of the first turntable 413, and the first placement area 414 is an arc-shaped placement surface. There is a gap between the outer edge of the first turntable 413 and the first placement area 414, and multiple branch pipes 100 pass through the gap between the first placement area 414 and the first turntable 413. The outer periphery of the first turntable 413 includes a first main body 415 that can squeeze and close the branch pipe 100. The first main body 415 referred to here is the outer contour of the first turntable 413, and also includes a notch portion 416 that can allow one of the branch pipes 100 to be turned on. There are two notch portions 416. The first conduction position 411 and the second conduction position 412 respectively correspond to the positions of the two notches 416 for one of the branch pipes 100 to be turned on.

[0117] Preferably, the angle between the two notches 416 and the rotation axis of the first rotating disk 413 is greater than the angle between the two branch pipes 100 at both ends of the first placement surface and the rotation axis of the first rotating disk 413. In the present invention, the angle is 180°. Thus, when all the branch pipes 100 are located between the two notches 416, all the branch pipes 100 can be in the off state. At the same time, no matter how the first rotating disk 413 rotates, only one of the two notches 416 will overlap with the position of the branch pipe 100 and turn it on, avoiding misoperation.

[0118] like Figure 4 , Figure 6 and Figure 8As shown, in the present embodiment, the second switching mechanism 420 also includes a second placement area 426 arranged on the outer peripheral side of the second turntable 423, and there are two second placement areas 426, which are arranged on both sides of the second turntable 423. The exhaust pipe 200 and the inflation pipe 300 are arranged in the second placement areas 426 on both sides, and the exhaust pipe 200 and the inflation pipe 300 both pass through the gap between the second placement area 426 and the second turntable 423. The outer periphery of the second turntable 423 includes a second main body 425 capable of squeezing and sealing the exhaust pipe 200 or the inflation pipe 300 and a recessed portion 424 capable of accommodating the exhaust pipe 200 or the inflation pipe 300. The first travel area 421 corresponds to the position where the recessed portion 424 allows the exhaust pipe 200 to pass through, and the second travel area 422 corresponds to the position where the recessed portion 424 allows the inflation pipe 300 to pass through.

[0119] Further, in the present invention, the first travel area 421 and the second travel area 422 occupy the entire outer edge of the second rotating disk 423, and the first travel area 421 and the second travel area 422 each occupy half of the outer edge of the second rotating disk 423, that is, the angle between the two ends of the second travel area 422 and the rotation axis of the second rotating disk 423 is 180°. This is consistent with the angle between the two notches of the first rotating disk 413 and the rotation axis of the first rotating disk 413, so that when the first rotating disk 413 and the second rotating disk 423 rotate in conjunction, each time the first rotating disk 413 rotates from the first conducting position 411 to the second conducting position 412, the second rotating disk 423 can rotate through the boundary between the first travel area 421 and the second travel area 422.

[0120] In this embodiment, the multi-way extraction and charging switching device 10 further includes an air pump 700, the extraction pipe 200 includes an extraction branch pipe 210 connected to the branch pipe 100 and an exhaust branch pipe 320 connected to the outside, and the charging pipe 300 includes an intake branch pipe connected to the outside and an inflation branch pipe 310 connected to the branch pipe 100. The other ends of the extraction branch pipe 210 and the intake branch pipe are connected to the intake end of the air pump 700, and the other ends of the inflation branch pipe 310 and the exhaust branch pipe 320 are connected to the outlet ends of the air pump 700.

[0121] During operation, air enters the air pump 700 from the air extraction branch pipe 210 and / or the air intake branch pipe, and is discharged from the air charging branch pipe 310 and / or the air exhaust branch pipe 320 after being pressurized by the air pump 700. When the multi-way air extraction and charging switching device 10 is in the air extraction mode, the air intake branch pipe and the air charging branch pipe 310 are closed, and air enters the air pump 700 from the air extraction branch pipe 210 and is pressurized, and is discharged to the outside from the air exhaust branch pipe 320, thereby achieving air extraction of the air extraction branch pipe 210; when the multi-way air extraction and charging switching device 10 is in the air charging mode, the air extraction branch pipe 210 and the air exhaust branch pipe 320 are closed, and air enters the air pump 700 from the air intake branch pipe and is pressurized, and is discharged from the air charging branch pipe 310, thereby achieving air charging of the air charging branch pipe 310. With such a structure, only one air pump 700 is used to realize the switching between pumping and charging. Compared with the prior art in which two air pumps 700 are arranged to control pumping and charging respectively, it has the advantages of simple structure, simple control logic, small size, low power consumption and low cost. Of course, as mentioned above, the solution of using two air pumps 700 or two air valves to control pumping and charging respectively is also applicable to the multi-way pumping and charging switching device 10.

[0122] In summary, the actual control logic of the multi-way pumping and inflating switching device 10 is as follows: it includes multiple starting angles, each starting angle corresponds to the position of conducting one of the branch pipes 100 for inflation; multiple shut-off angles, which are obtained by rotating each starting angle 180°; and a shut-off angle, which can shut off all the branch pipes 100. When a branch pipe 100 needs to be unloaded, it is rotated to the corresponding starting angle to conduct the branch pipe 100 for inflation, thereby controlling the unloading of the seasoning. When the seasoning enters the siphon unloading state, it is rotated to the shut-off angle. When it is necessary to stop unloading, it is rotated to the shut-off angle again to end the siphon unloading state of the seasoning, and then rotated to the shut-off angle again to complete a complete set of unloading operations. It can be seen that in the present invention, the control module 500 only needs to control the multi-way pumping and inflating device to rotate to a specific angle to realize the rotation conduction of the branch pipe 100 and the multi-way pumping and inflating switching. The control logic is simple, making software development easy.

[0123] Example 2

[0124] Combination Fig.10 and Fig.11 Compared with the embodiment 1, the multi-channel liquid seasoning discharging mechanism of this embodiment adopts a different multi-channel pumping and charging switching device 10, and the specific differences are as follows:

[0125] The multi-way pumping and charging switching device 10 includes a first movable plate 430 and a second movable plate 440 attached to the first movable plate 430. The first movable plate 430 and the second movable plate 440 can slide relative to each other along the attached end surfaces. The attached end surfaces of the first movable plate 430 are provided with a pumping hole 431 and a charging hole 432. The attached end surfaces of the second movable plate 440 are provided with a vent hole 441 that is connected to the air pressure chamber 610 through the branch pipe 100.

[0126] The relative positions of the first movable plate 430 and the second movable plate 440 when sliding include multiple inflation positions where one of the multiple vent holes 441 overlaps with the inflation hole 432 and multiple exhaust positions where one of the multiple vent holes 441 overlaps with the exhaust hole 431. The inflation position and the exhaust position do not overlap with each other to avoid the situation where the vent hole 441 is in the exhaust state and the inflation state at the same time.

[0127] When air extraction is required, the first movable plate 430 and the second movable plate 440 are driven to move relative to each other so that the corresponding vent hole 441 coincides with the air extraction hole 431. At this time, the vent hole 441 is connected with the air extraction hole 431, so that air extraction can be achieved in the vent hole 441. When air intake and inflation are required, the first movable plate 430 and the second movable plate 440 are driven to move relative to each other so that the corresponding vent hole 441 is connected with the inflation hole 432, so that inflation can be achieved in the vent hole 441.

[0128] That is to say, the present invention can switch any vent 441 for pumping and inflation only by controlling the positions of the first movable plate 430 and the second movable plate 440. Controlling the relative movement of the first movable plate 430 and the second movable plate 440 only requires one or two action mechanisms. Compared with the prior art, this significantly reduces the number of control components, reduces costs, and simplifies control logic. At the same time, fewer components can also reduce the volume and increase reliability.

[0129] The relative movement between the first movable plate 430 and the second movable plate 440 can be achieved through a variety of structures, one of which is that the first movable plate 430 or the second movable plate 440 is connected to a rotating motor 450 that can drive the two to rotate relative to each other, and the rotating axis of the rotating motor 450 is placed on the adjacent end surfaces, and the distances between the exhaust hole 431, the inflation hole 432 and the ventilation hole 441 and the rotating axis are equal, and the angles between the exhaust hole 431 and the inflation hole 432 and the rotating axis are greater than the angles between any two ventilation holes 441 and the rotating axis, and the control module 500 is connected to the rotating motor 450.

[0130] Since the distances between the air extraction hole 431, the air filling hole 432 and the vent hole 441 and the rotation axis are equal, the relative running tracks of the air extraction hole 431, the air filling hole 432 and the vent hole 441 are overlapping arcs, thereby enabling the air extraction hole 431, the air filling hole 432 to be connected to any vent hole 441. Making the angle between the air extraction hole 431 and the air filling hole 432 and the rotation axis greater than the angle between any two vent holes 441 and the rotation axis can avoid the situation where two vent holes 441 are connected to the air extraction hole 431 and the air filling hole 432 respectively, causing erroneous air extraction or erroneous air filling.

[0131] In this structure, the control module 500 only needs to control the rotation of the rotating motor 450 to different angles to achieve the switching of pumping and charging. There are fewer components and the control logic is simple, which can greatly reduce costs and increase service life.

[0132] Combination Fig.12 and Fig.13 Another scheme for controlling the relative movement of the first movable plate 430 and the second movable plate 440 is as follows: the first movable plate 430 and / or the second movable plate 440 is connected to a first straight line 433 motor that can drive the two to move relative to each other along a first straight line 433 on the adjacent end surfaces; the exhaust hole 431 and the inflation hole 432 are arranged on the first movable plate 430 along the first straight line 433; a plurality of ventilation holes 441 are arranged on the second movable plate 440 along the first straight line 433; the distance between the air holes and the inflation holes 432 is greater than the distance between any two ventilation holes 441; and the control module 500 is connected to the first straight line 433 motor.

[0133] Since the air extraction hole 431, the air filling hole 432 and the plurality of vent holes 441 are arranged along the first straight line 433, the relative running tracks of the air extraction hole 431 and the air filling hole 432 can overlap with the relative running track of the vent hole 441. Thus, the air extraction hole 431 and the air filling hole 432 can be connected with the vent hole 441. Since the distance between the air extraction hole 431 and the air filling hole 432 is greater than the distance between any two vent holes 441, there will be no situation where the air extraction hole 431 and the air filling hole 432 are connected with two vent holes 441 at the same time, resulting in erroneous inflation or erroneous extraction.

[0134] In this structure, it is also only necessary to control the first linear motor 433 to translate to different positions to realize the selective conduction and the switching of the vent hole 441 for pumping and filling. It has the advantages of fewer components, simple control logic and low cost.

[0135] Combination Fig.14 and Fig.15Another scheme for controlling the relative movement of the first movable plate 430 and the second movable plate 440 is as follows: the first movable plate 430 is connected to a second linear motor 434 capable of driving it to translate along a second straight line 434 on the contacting end surfaces, the exhaust hole 431 and the inflation hole 432 are arranged on the first movable plate 430 along the second straight line 434, the second movable plate 440 is connected to a third linear motor capable of driving it to translate along a third straight line on the contacting end surfaces, a plurality of ventilation holes 441 are arranged on the movable plate along the third straight line, the second straight line 434 and the third straight line intersect, and the control module 500 connects the second linear motor 434 and the third linear motor.

[0136] In this solution, the second straight line 434 and the third straight line are perpendicular to each other to more conveniently control the relative movement position. Of course, the second straight line 434 and the third straight line are not limited to being perpendicular to each other, as long as there is an angle between them.

[0137] The air extraction holes 431 and the air charging holes 432 are arranged on the first movable plate 430 along the second straight line 434, and the plurality of air vents 441 are arranged on the movable plate along the third straight line. Therefore, when the first movable plate 430 and the second movable plate 440 move relative to each other, one of the plurality of air vents 441 can intersect with the air extraction hole 431 or the air charging hole 432, thereby achieving air extraction and air charging of the air vents 441. Since there is only one intersection point between the first straight line 433 and the second straight line 434, there is no problem of two air vents 441 overlapping with the air extraction hole 431 and the air charging hole 432, respectively, resulting in wrong air charging or air extraction, and the design is more convenient.

[0138] In this structure, the second linear motor 434 and the third linear motor are controlled to move relative to each other to achieve the selective conduction of the branch pipe 100 and the switching between pumping and charging.

[0139] Example 3

[0140] The difference between the multi-channel liquid seasoning discharge mechanism of this embodiment and embodiments 1 and 2 lies in the different structure of the discharge chamber 20. As for the multi-channel pumping and charging switching device 10 of this embodiment, it can adopt the scheme in embodiment 1 or the scheme in embodiment 2.

[0141] The discharge cavity 20 in this embodiment is as follows Fig.11 As shown, it includes a containing chamber 600 for placing liquid and a liquid outlet passage 630 connecting the containing chamber 600 with the outside. The discharge chamber 20 also includes a liquid outlet portion 800 detachably connected to the containing chamber 600, and the liquid outlet passage 630 is arranged in the liquid outlet portion 800.

[0142] Since the feeding amount of liquid seasoning is small, usually within 10ml, in order to accurately control the feeding amount, in actual design, the flow rate of liquid seasoning per unit time should be appropriately reduced to appropriately extend the feeding time, thereby improving the feeding accuracy. However, this also leads to a thinner pipe diameter of the liquid outlet passage 630. It is more likely to cause scaling and clogging problems. Therefore, the present invention places the liquid outlet passage 630 separately in the liquid outlet part 800 that is detachably connected to the accommodating chamber 600. After a period of use, it can be removed for cleaning, thereby solving the problem of scaling and clogging of the seasoning during long-term use. The discharge chamber 20 can always maintain a good working accuracy.

[0143] The present invention also provides a cooking machine, comprising the multi-channel liquid seasoning discharging mechanism as described in Embodiment 1, Embodiment 2 and Embodiment 3.
