[0001] This application is a divisional application of a prior patent application. The prior patent application number is 202510084617.4, the application date is January 20, 2025, and the application title is "Liquid food preparation equipment and its cleaning method, control device and storage medium". Technical Field

[0003] Existing coffee machines, such as those used for coffee makers, require cleaning of the brewing tank during operation, typically using cleaning agents. These agents are usually added manually. However, to achieve a more compact design, current coffee machines generally arrange the agent storage compartment, powder weighing container, and brewing tank sequentially along the direction of gravity. During the process of delivering the agent from the compartment to the brewing tank, the agent first passes through the weighing container and easily comes into contact with its inner wall, resulting in some agent residue remaining there. In the next brewing session, this residue mixes with the coffee powder and enters the brewing tank, degrading coffee quality and causing contamination. Summary of the Invention

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0027] Please see Figures 1 to 11 This invention provides a liquid food preparation device, which includes a housing and multiple functional components disposed inside or outside the housing. The types and quantities of these functional components can be selected according to actual needs, and may include, but are not limited to, a medicine storage device 100, a weighing device 300, a brewing device 400, and a control device 600; further, a powder supply device may also be included. It should be noted that this design does not limit the specific orientation of the liquid food preparation device; however, for ease of understanding, the direction of gravity is used as an orientation reference in the following embodiments, and the direction of gravity has an upward and a downward orientation that are relatively opposite to each other.

[0028] The storage device 100 includes a drug outlet 111, which is openable and closable. The storage device 100 is primarily a functional component for storing and discharging drugs. The drugs are generally liquid, solid, or gaseous products used for cleaning. Of course, the drugs may also have further functions such as disinfection and sterilization.

[0029] Based on this, the drug storage device 100 generally includes a drug storage chamber 110, within which a drug storage cavity is defined, and the drug storage cavity is provided with a drug outlet 111. The drug storage cavity can be one or at least two. When there are at least two drug storage cavities, each cavity can be used to store the same type of drug or to store different types of drugs.

[0030] Correspondingly, the medicine outlet 111 is generally set as the common outlet of all medicine storage chambers, that is, any medicine is discharged outward through the medicine outlet 111. However, the medicine outlet 111 is not limited to only one, and can be set to one or at least two depending on actual needs. In order to enable the medicine in the medicine storage chamber to be discharged outward through the medicine outlet 111 autonomously without the aid of power, the medicine outlet 111 is generally opened at the bottom of the medicine storage chamber and the opening is set downward.

[0031] The medicine outlet 111 is openable and closable, meaning it has both an open and closed state, and can autonomously switch between these states as needed. The method for achieving this is not limited; it can include, but is not limited to, a valve body and cover plate movable at the medicine outlet 111, or the medicine storage chamber 110 being movable as a whole, allowing the medicine outlet 111 to rotate to an upward-facing, closed state, and to rotate to a downward-facing, open state.

[0032] The powder supply device includes a material outlet, which can be closed. The powder supply device is primarily a functional component used to generate or store powder, and to discharge the powder through the material outlet. The powder is the material that can be used by the subsequent brewing device 400 to brew a liquid food product. It can generally be, but is not limited to, beans, tea leaves, milk powder, etc., and the corresponding liquid food can be, but is not limited to, coffee, soy milk, tea soup, milk tea, etc. For ease of understanding, the following embodiments will use coffee beans as the powder and coffee as the liquid food as an example.

[0033] Similarly, the material outlet can be configured as one or at least two, depending on actual needs. To allow the coffee powder in the powder supply device to be discharged autonomously through the material outlet without power, the material outlet is generally located at the bottom of the powder supply device, with its opening facing downwards. The material outlet is operable, meaning it has both an open and closed state, and can autonomously switch between these states as needed. The method for achieving this is not limited; it can include, but is not limited to, having a valve body and cover plate movable at the material outlet, or controlling the movable configuration of at least one part of the powder supply device with a material outlet, allowing the material outlet to rotate to an upward-facing, closed state, and to rotate to a downward-facing, open state.

[0034] In view of the above, in one design, the coffee powder supply device may include a coffee powder storage device. The coffee powder storage device is used to directly store readily available external coffee powder. Specifically, the coffee powder storage device defines a coffee powder storage chamber. The coffee powder storage chamber has a coffee powder outlet. The coffee powder storage chamber can be configured as one or at least two. When there are at least two coffee powder storage chambers, each chamber can be used to store the same type of coffee powder or to store different types of coffee powder. Correspondingly, the coffee powder outlet is generally configured as a common outlet for all coffee powder storage chambers, meaning that all coffee powder is discharged outwards through the coffee powder outlet. However, the coffee powder outlet is not limited to only one; it can be configured as one or at least two depending on actual needs.

[0035] Alternatively, in one design, the coffee powder supply device may include a grinding device 200. The grinding device 200 is used to grind coffee beans to obtain coffee powder. Specifically, the grinding device 200 generally includes a grinding cylinder and a burr disc movably disposed within the grinding cylinder. Furthermore, the grinding device 200 generally includes a grinding output structure 210 connected to a connecting pipe of the grinding cylinder. The grinding output structure 210 has a grinding channel 211 extending along the direction of gravity. The grinding channel 211 has a grinding outlet 213. The grinding outlet 213 discharges the coffee powder transferred from the grinding cylinder to the grinding channel 211. The grinding outlet 213 constitutes the aforementioned material outlet.

[0036] The grinding device 200 can directly receive coffee beans from outside the machine housing. Alternatively, in one design, the powder supply device may include the grinding device 200 and a bean storage device. The grinding device 200 is configured as described above. The bean storage device includes a bean hopper. The bean hopper is a container component that provides a certain space to hold coffee beans. In practical applications, one or more bean hoppers can be set according to actual needs. When there are several bean hoppers, each bean hopper can be used to store the same type of coffee beans or to store different types of coffee beans. It should be noted that when there are several bean hoppers and they store different types of coffee beans, the grinding device 200 can be set up one-to-one with each bean hopper. It can be understood that the coffee beans stored in each bean hopper can be used to prepare different types of beverages according to actual needs. In this case, different types of coffee beans and / or different types of beverages can be set up one-to-one with different grinding devices 200, so that the burr parameters of the grinding device 200 are well matched with the type of coffee beans and / or beverage, so as to prepare beverages of higher quality. Alternatively, the same grinding device 200 can be adapted to at least two bean hoppers. In this case, different types of coffee beans and / or different types of beverages can be matched with different burr parameters of the same grinding device 200 to prepare beverages of higher quality.

[0037] When the powder supply device includes a grinding device 200 and a bean storage device as described above, the material outlet can be located at the bean hopper, depending on actual needs. That is, the material outlet can specifically discharge the coffee beans stored in the bean hopper. Alternatively, the material outlet can be located at the grinding device 200 as described above.

[0038] The weighing device 300 is equipped with a weighing channel 311, which can be switched on and off. The weighing device 300 is used to measure the weight of the coffee powder. The weighing device 300 is generally located between the material outlet of the powder supply device and the brewing inlet 412 of the brewing device 400. That is, the weighing device 300 can weigh the coffee powder discharged from the powder supply device and then transfer the coffee powder to the brewing device 400 as needed.

[0039] In one design, the weighing device 300 includes a weighing container and a weighing device 340 connected to each other. The weighing container includes a container body 310, an opening and closing member 320 movably disposed on the container body 310, and a power component 330 driving the opening and closing member 320. The container body 310 is provided with a weighing channel 311, which is provided with a weighing inlet 312 and a weighing outlet 313. Under the drive of the power component 330, the opening and closing member 320 can movably open and close the weighing outlet 313 to realize the switching of the weighing channel 311.

[0040] In view of the above, if the weighing inlet 312 is connected to the material outlet, and the weighing outlet 313 is closed or disconnected from the brewing inlet 412, the container body 310 can receive and contain the coffee powder discharged from the material outlet. The weighing device 340 starts operating and performs the weighing function in real time or with a delay. At this time, the weighing device 300 is in weighing mode. Of course, the container body 310 can also receive and contain the coffee powder discharged from the material outlet, but the weighing device 340 stops operating and does not perform the weighing function. At this time, the weighing device 300 is in a non-weighing pre-acceptance mode. If the weighing inlet 312 is connected to the material outlet and the weighing outlet 313 is connected to the brewing inlet 412, the weighing channel 311 is set to normally open, so that when the coffee powder is conveyed from the powder supply device to the brewing device 400, the coffee powder can pass freely and unobstructed through the weighing channel 311. The weighing device 300 mainly serves as a transitional device for the coffee powder and does not perform the weighing function. At this time, the weighing device 300 is in a non-weighing transitional mode.

[0041] The brewing device 400 includes a brewing inlet 412, which is openable and closable. The brewing device 400 may include, but is not limited to, a brewing cylinder 410, two pistons, and a corresponding drive mechanism. The brewing cylinder 410 forms a brewing chamber 411, which extends substantially along the direction of gravity and has a brewing inlet 412 at the upper end and a brewing opening 413 at the lower end. Driven by the drive mechanism, at least one of the two pistons is movable. For ease of understanding, in the following embodiments, the two pistons are respectively named a first piston 420 and a second piston 430. Optionally, the second piston 430 is positioned closer to the brewing inlet 412, and can move into the brewing chamber 411 via the brewing inlet 412, and can also move out of the brewing chamber 411 via the brewing inlet 412. And / or optionally, the first piston 420 is positioned closer to the brewing opening 413, and can move into the brewing chamber 411 via the brewing opening 413, and can also move out of the brewing chamber 411 via the brewing opening 413. When both the first piston 420 and the second piston 430 are moved into the brewing chamber 411, the first piston 420 and / or the second piston 430 can be movably positioned so that the first piston 420 and the second piston 430 can move closer to each other and further away from each other.

[0042] Furthermore, the liquid food preparation equipment also includes a liquid outlet pipe 710, a first pump body, and a first solenoid valve. The liquid outlet pipe 710 passes through a piston member to connect to the brewing chamber 411 and is connected to the liquid outlet. The first pump body is located at the liquid outlet pipe 710 and is used to drive the liquid in the brewing chamber 411 to be discharged through the liquid outlet pipe 710 to the liquid outlet. The first solenoid valve is located at the liquid outlet pipe 710 to control the opening and closing of the liquid outlet pipe 710. Specifically, the liquid outlet pipe 710 may pass through a second piston member 430. The liquid food preparation equipment has a liquid outlet on the outer wall of its casing. The liquid outlet can discharge the finally prepared liquid food, such as coffee.

[0043] In addition, the liquid food preparation equipment also includes a water storage container 810, a liquid inlet pipe 820, a second pump body, and a second solenoid valve 830. The water storage container 810 is used to generate or store liquid. Specifically, for example, the water storage container 810 includes a boiler assembly that can heat externally supplied cold water to obtain hot water via a fixed heating component. And / or the water storage container 810 includes a cold water inlet structure for storing or supplying external cold water. The liquid inlet pipe 820 passes through a piston member to connect to the brewing chamber 411 and is connected to the water storage container 810; the second pump body is located at the liquid inlet pipe 820 and is used to drive the liquid in the water storage container 810 to enter the brewing chamber 411 via the liquid inlet pipe 820; the second solenoid valve 830 is located at the liquid inlet pipe 820 to control the opening and closing of the liquid inlet pipe 820. Specifically, the liquid inlet pipe 820 may pass through the first piston member 420. The second solenoid valve 830 can be configured to allow access to a cold water inlet structure or boiler assembly, so as to supply hot or cold water to the brewing chamber 411 as needed.

[0044] In view of the above, the liquid food preparation equipment has a dispensing state. In the dispensing state, the medicine outlet 111, the weighing channel 311 and the brewing inlet 412 are arranged sequentially along the direction of gravity and are kept in communication. A dispensing channel for medicine to flow is defined between the medicine outlet 111 and the brewing inlet 412. The dispensing channel is at least partially located in the weighing channel 311 and is spaced apart from any channel wall of the weighing channel 311.

[0045] In the technical solution provided by this invention, by adjusting the relative positional relationship between the medicine outlet 111 and the brewing inlet 412, the orientation and size of the medicine dispensing channel can be adjusted accordingly. By adjusting the orientation and size relationship between the weighing channel 311 and the medicine dispensing channel, and maintaining the continuity of the weighing channel 311, it can be ensured that during the process of the medicine entering the brewing inlet 412 through the weighing channel 311 from the medicine outlet 111, it will not come into contact with any channel wall of the weighing channel 311. This prevents the medicine from leaving residues in the weighing channel 311, and thus prevents contamination of the final liquid food by contaminating the powder in the weighing channel 311. This helps to improve the reliability of the entire machine.

[0046] It is understandable that, since the reagent outlet 111 is positioned downwards and the brewing inlet 412 is generally positioned upwards, the dispensing channel defined between the reagent outlet 111 and the brewing inlet 412 is generally arranged along the direction of gravity. Specifically, if the reagent outlet 111 has a first orthographic projection area along the direction of gravity, and the brewing inlet 412 has a second orthographic projection area along the direction of gravity, and the first and second orthographic projection areas at least partially overlap to form a first overlapping area, then the dispensing channel can be defined by the first overlapping area extending along the direction of gravity. Based on this, the dispensing channel is generally set as a straight channel. It should be noted that the dispensing channel is not limited to a physical channel, that is, the dispensing channel is not limited to being formed by a physical structure; it can refer to the collection area of ​​almost all the paths taken by the coffee powder transferred from the reagent outlet 111 to the brewing inlet 412.

[0047] Based on this, the weighing channel 311 is generally formed by opening the container body 310, and it can be a curved channel, a straight channel, or a composite channel composed of curved and straight channels. To ensure that, during the dispensing process, the dispensing channel is at least partially located within the weighing channel 311 and maintains a distance from any channel wall of the weighing channel 311, the projected areas of any channel segment of the weighing channel 311 along the direction of gravity at least partially overlap, forming a second overlapping area; the first overlapping area falls within the second overlapping area and maintains a distance from the edge of the first overlapping area. That is, regardless of whether any channel segment of the weighing channel 311 is a curved or straight segment, it penetrates at least in a local radial region along the direction of gravity, forming a second overlapping area in the direction of gravity. Therefore, the first overlapping area can exactly coincide with the second overlapping area, i.e., their shapes and sizes are compatible. Alternatively, the first overlapping area can fall within the second overlapping area, but its size is smaller than the size of the second overlapping area. In this way, it is sufficient to ensure that the medicine discharged out through the medicine outlet 111 will not come into contact with the inner wall of the weighing channel 311 when it passes through the weighing channel 311.

[0048] To facilitate processing and to ensure stable flow rate and volume of coffee powder and reagents as they flow through the weighing channel 311, the weighing channel 311 is generally configured as a straight channel. That is, if the weighing channel 311 has a first central axis, then the first central axis is a straight line. The first central axis can be a straight line extending along the direction of gravity or a straight line that is inclined to a certain extent relative to the direction of gravity.

[0049] Specifically, in the dropping state, the weighing channel 311 has a first central axis, and the dropping channel has a second central axis. Both the first and second central axes extend along the direction of gravity, and are adjacent to and parallel; or they are collinear. This maximizes the overlap between the weighing channel 311 and the dropping channel, thus maximizing the radial cross-sectional area of ​​the dropping channel within the limited radial cross-sectional area of ​​the weighing channel 311.

[0050] Based on the above embodiments, in a specific application of liquid food preparation equipment, in the dispensing state, the components in the drug storage device 100 with at least a drug outlet 111, the weighing device 300 with at least a weighing channel 311, and the brewing device 400 with at least a brewing inlet 412 are all fixed in place. Specifically, at least the drug storage chamber 110 in the drug storage device 100, at least the container body 310 in the weighing device 300, and at least the brewing cylinder 410 in the brewing device 400 are fixed in position relative to the machine casing, so that the relative positions of the drug outlet 111, the weighing channel 311, and the brewing inlet 412 remain fixed regardless of whether the dispensing state is in progress. When switching to the dispensing state, it is necessary to switch the drug outlet 111 open, the weighing channel 311 to remain open, and the brewing inlet 412 to be open; while when switching to other states, at least a portion of the drug outlet 111, the weighing channel 311, and the brewing inlet 412 are closed or isolated.

[0051] Alternatively, to make the liquid food preparation equipment more flexible and versatile in its operation, in another specific application of the liquid food preparation equipment, at least one of the following three components is movable: the medicine storage device 100 has at least a component with a medicine outlet 111; the weighing device 300 has at least a component with a weighing channel 311; and the brewing device 400 has at least a component with a brewing inlet 412. This allows the liquid food preparation equipment to be switched to a dispensing state. Specifically, at least one of the following components—at least the medicine storage chamber 110 in the medicine storage device 100, at least the container body 310 in the weighing device 300, and at least the brewing cylinder 410 in the brewing device 400—is movable relative to the machine casing. Thus, when it is necessary to switch to the dispensing state, the medicine storage chamber 110, the container body 310 and / or the brewing tank 410 must first be moved so that the relative positions of the medicine outlet 111, the weighing channel 311 and the brewing inlet 412 reach the target requirements, and then the medicine outlet 111 is switched to open, the weighing channel 311 is kept open and the brewing inlet 412 is switched to open.

[0052] Furthermore, once the liquid food preparation equipment has switched to the dispensing state, in one design, the components in the drug storage device 100 with at least a drug outlet 111, the weighing device 300 with at least a weighing channel 311, and the brewing device 400 with at least a brewing inlet 412 are fixed in position. That is, at least the drug storage chamber 110 in the drug storage device 100, at least the container body 310 in the weighing device 300, and at least the brewing cylinder 410 in the brewing device 400 are all fixed in position relative to the machine casing, sufficiently ensuring that any channel wall of the dispensing channel and the weighing channel 311 remains spaced apart.

[0053] Alternatively, in another design, at least one of the following components may be movable: a component with a medicine outlet 111 in the medicine storage device 100; a component with a weighing channel 311 in the weighing device 300; and a component with a brewing inlet 412 in the brewing device 400. This ensures that the medicine dispensing channel and any channel wall of the weighing channel 311 remain separated. In other words, at least one of the following components—at least the medicine storage chamber 110 in the medicine storage device 100, at least the container body 310 in the weighing device 300, and at least the brewing cylinder 410 in the brewing device 400—needs to remain movable within a preset stroke range to maintain the separation between the medicine dispensing channel and any channel wall of the weighing channel 311. Specifically, for example, when the weighing channel 311 is not designed as a straight channel but as a curved or zigzag channel, by driving the container body 310 along a preset trajectory, it can be ensured that the medicine remains separated from the side wall of each channel segment as it flows through different segments of the weighing channel 311.

[0054] Based on the above, when the liquid food preparation equipment also includes a powder supply device, the powder supply device is provided with a material outlet, which can be closed. Since the weighing device 300 is also used to weigh or transfer the powder discharged from the powder supply device as described above, the weighing inlet 312 of the weighing channel 311 may need to be connected to either the material outlet or the reagent outlet 111. In one embodiment, at least one of the following three components is movable: the powder supply device has at least a material outlet component, the reagent storage device 100 has at least a reagent outlet 111 component, and the weighing device 300 has at least a weighing channel 311 component, so that the liquid food preparation equipment has a powder-receiving state where the weighing channel 311 is located below the material outlet, and a reagent-discharging state. That is, at least one of the following components is movable relative to the housing: the powder supply device has at least a powder storage bin / grinding output structure 210, the weighing device 300 has at least a container body 310, and the reagent storage device 100 has at least a reagent storage bin 110. During its operation, the liquid food preparation equipment has a powder receiving state in which the weighing channel 311 is located below the material outlet, and a drug discharging state in which the weighing channel 311 is located below the drug outlet 111.

[0055] For the aforementioned weighing device 300, when in the powder receiving state, the power component 330 can drive the opening / closing component 320 to open the weighing outlet 313, and the weighing device 340 stops operating and its weighing function is not activated. At this time, the weighing device 300 is in the aforementioned transition mode. Alternatively, when in the powder receiving state, the power component 330 can drive the opening / closing component 320 to close the weighing outlet 313, and the weighing device 340 starts operating and its weighing function is activated. At this time, the weighing device 300 is in the aforementioned weighing mode.

[0056] Furthermore, both the material outlet and the reagent outlet 111 can be configured to be directly and detachably connected to the weighing inlet 312 of the weighing channel 311. Alternatively, in one embodiment, the liquid food preparation equipment also includes a powder supply device and a conveying component 500. The powder supply device has a material outlet that can be closed. The conveying component 500 is provided with a conveying channel 510, which has a conveying inlet 511 and a conveying outlet 512. The weighing channel 311 is fixedly located below the conveying outlet 512. The component in the powder supply device that has at least a material outlet and the component in the reagent storage device 100 that has at least a reagent outlet 111 are respectively movably configured so that the liquid food preparation equipment can have a powder receiving state when the material outlet is above the conveying inlet 511 and a reagent discharging state when the reagent outlet 111 is above the conveying inlet 511. That is, when the conveying channel 510 is connected between the material outlet and the weighing channel 311, it is in the powder receiving state; when the conveying channel 510 is connected between the reagent outlet 111 and the weighing channel 311, it is in the reagent discharging state. The conveying component 500 separates the weighing channel 311 and the reagent outlet 111, as well as the weighing channel 311 and the material outlet, and forms a certain extension length, which helps to guide the coffee powder or reagent to the desired flow direction during the flow along the conveying channel 510.

[0057] When the positions of the conveying component 500 and the weighing device 300 are fixed, if the drug storage device 100 and the powder supply device are arranged side by side in the horizontal direction above the weighing device 300, then in one embodiment, at least one of the powder storage bin / grinding output structure 210 in the powder supply device, at least the container body 310 in the weighing device 300, and at least the drug storage bin 110 in the drug storage device 100 can be movably arranged relative to the housing, so that the conveying inlet 511 can be located below the material outlet, or the conveying inlet 511 can be located below the drug outlet 111.

[0058] Alternatively, in another embodiment, at least the powder storage bin / grinding output structure 210 in the powder supply device, at least the container body 310 in the weighing device 300, and at least the medicine storage bin 110 in the medicine storage device 100 are all fixedly arranged relative to the casing. In this case, two material inlets 511 are arranged radially along the material conveying channel 510, namely the first material inlet and the second material inlet, respectively. The material outlet is fixedly located above the first material inlet, and the medicine outlet 111 is fixedly located above the second material inlet. In this way, the conveying component 500, through its structural design, can be adapted to the installation positions of the medicine storage device 100, the powder supply device, and the weighing device 300. For example, when the medicine storage device 100 and the powder supply device are arranged side by side in the transverse direction above the weighing device 300, the conveying component 500 can guide coffee powder or medicine to flow to the weighing channel 311 without moving the medicine storage device 100 and the powder supply device.

[0059] Based on the above, the feeding component 500 includes a partition structure disposed between the first feeding inlet and the second feeding inlet. That is, the first feeding inlet and the second feeding inlet can be separated from each other and independently disposed laterally, preventing the reagent outlet 111 from mistakenly entering the first feeding inlet, or preventing coffee powder from mistakenly entering the second feeding inlet. Alternatively, the first feeding inlet and the second feeding inlet can be connected to each other radially along the feeding channel 510. This helps simplify the overall structure of the feeding component 500 and makes it easier to process and shape.

[0060] In a further embodiment, the opening area of ​​the first material inlet is larger than that of the second material inlet. This design, with a larger opening area for the first material inlet, allows for a greater flow rate of coffee powder discharged through the material outlet, facilitating faster and easier transport of the coffee powder through the conveying channel 510 to the weighing channel 311. The reagents are generally granular or pellet-shaped, and the dosage is typically small. Therefore, by designing a smaller opening area for the second material inlet, more space can be allocated to maximizing the opening area of ​​the first material inlet. In practical applications, the conveying channel 510 includes a main channel section connecting the first material inlet and the material outlet 512, and a bypass channel section connecting the second material inlet and the main channel section. The bypass channel section extends radially outward from one side of the main channel section.

[0061] Specifically, when the powder supply device includes a grinding device 200, and the grinding device 200 includes a grinding output structure 210, the material conveying component 500 can be fixedly connected above the grinding output structure 210, and the material conveying channel 510 and the grinding channel 211 are connected, that is, the grinding channel 211 is provided with a grinding opening 212, and the grinding opening 212 is connected to the material conveying outlet 512. The reagent outlet 111 can selectively connect to the material conveying inlet 511; the weighing channel 311 can selectively connect to the grinding outlet 213.

[0062] Furthermore, based on any of the above embodiments, in a further embodiment, the liquid food preparation equipment may also include a residue box, a prompting module, an input module, and / or sensor components.

[0063] The brewing container is movably configured relative to the brewing cylinder 410, having an in-position state located below the brewing cylinder 410 and an out-of-position state moved away from below the brewing cylinder 410. In the in-position state, the brewing container is used to collect waste such as coffee cake, coffee grounds, and residual liquid discharged from the brewing cylinder 410; while in the out-of-position state, it facilitates the user to empty the waste collected in the brewing container.

[0064] The prompt module can be installed on the liquid food preparation equipment; alternatively, the prompt module can be installed independently of the liquid food preparation equipment, and the two can communicate with each other wirelessly. The prompt module is used to issue prompt information, and the prompting methods can be, but are not limited to, voice broadcast, flashing indicator lights, buzzer sound, vibration, etc.

[0065] The input module is used to trigger command information and / or input values. This input module can be, but is not limited to, components such as a touch panel. The input interface of the input module has at least one preset parameter pre-set; when the user operates based on the input module, they can input values ​​for each preset parameter.

[0066] The sensor components can be configured according to actual needs, and can be one or at least two. When at least two sensor components are configured, each sensor component can be used to sense the same parameter or to sense different parameters. At least one of the sensor components can be used to sense the installation status of the slag box, and it can be, but is not limited to, a weight sensor, a photoelectric sensor, an image recognition sensor, etc.

[0067] Reference Figure 11 , Figure 11 This is a schematic diagram of the control device 600 for the hardware operating environment involved in the embodiment of the present invention.

[0068] like Figure 11As shown, the control device 600 may include: a processor 610, such as a central processing unit (CPU), a communication bus 620, a user interface 630, a network interface 640, and a memory 650. The communication bus 620 is used to enable communication between these components. The user interface 630 may include a display screen and an input unit such as a keyboard; optionally, the user interface 630 may also include a standard wired interface or a wireless interface. The network interface 640 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 650 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk storage device. Optionally, the memory 650 may also be a storage device independent of the aforementioned processor 610.

[0069] Those skilled in the art will understand that Figure 11 The structure shown does not constitute a limitation on the control device 600, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0070] like Figure 11 As shown, the memory 650, which serves as a storage medium, may include an operating system, a network communication module, a user interface 630 module, and a cleaning program for liquid food preparation equipment.

[0071] exist Figure 11 In the control device 600 shown, the network interface 640 is mainly used for data communication with the network server; the user interface 630 is mainly used for data interaction with the user; the processor 610 and the memory 650 in the control device 600 of the present invention can be set in the liquid food preparation equipment. The control device 600 calls the cleaning program of the liquid food preparation equipment stored in the memory 650 through the processor 610 and executes the cleaning method of the liquid food preparation equipment provided in the embodiment of the present invention.

[0072] This invention provides a cleaning method for liquid food preparation equipment, referring to... Figures 12 to 13 This is a flowchart illustrating a specific embodiment of a cleaning method for a liquid food preparation device according to the present invention.

[0073] Specifically, the cleaning methods for liquid food preparation equipment include: Step S100: Upon receiving the cleaning instruction, confirm whether the agent outlet 111, weighing channel 311 and brewing inlet 412 are properly installed; Driven by the drive mechanism, the brewing device 400 has a brewing mode. In the brewing mode, the first piston 420 is located inside the brewing chamber 411, and the second piston 430 moves out of the brewing chamber 411 through the brewing inlet 412, opening the brewing inlet 412 to receive coffee powder discharged from the powder supply device via the weighing device 300. Then, the second piston 430 enters the brewing chamber 411 through the brewing inlet 412. The first piston 420 and the second piston 430 approach each other, pressing the coffee powder received by the first piston 420 to obtain a coffee cake. Then, the second solenoid valve 830 connects the liquid inlet pipe 820, the water storage container 810, and the brewing chamber 411, and the second pump starts running, introducing hot water from the water storage container 810 into the brewing chamber 411 to extract the coffee cake.

[0074] The brewing device 400 also has a residue discharge mode. The residue to be discharged in the residue discharge mode can generally be the residue cake remaining after brewing and extraction, or the residue remaining in the brewing chamber 411 after brewing. The residue discharge mode can be an upward residue discharge operation, that is: controlling the second piston 430 to move upward from inside the brewing chamber 411 and disengage from the brewing inlet 412 to the outside of the brewing chamber 411; controlling the first piston 420 to move upward at least to be flush with the brewing inlet 412, so as to discharge the residue in the brewing chamber 411 upward. The residue discharge mode can also be a downward residue discharge operation, that is: controlling the first piston 420 to move downward from inside the brewing chamber 411 and disengage from the brewing opening 413 to the outside of the brewing chamber 411; controlling the second piston 430 to move downward at least to be flush with the opening of the brewing chamber 411, so as to discharge the residue in the brewing chamber 411 downward.

[0075] Therefore, the cleaning operation of the liquid food preparation equipment can be performed after one or at least two slag discharge modes. The slag discharge mode can be performed after one or at least two brewing modes. Preferably, after each brewing mode is completed, at least one slag discharge mode is performed from the brewing tank 410, after which at least one cleaning operation of the liquid food preparation equipment can be performed.

[0076] Cleaning commands can be generated manually by the user based on the input module. Alternatively, cleaning commands can be automatically executed by the program in conjunction with other working modes. For example, it can be set to perform one or more cleaning operations on the liquid food preparation equipment when the machine is turned on or restarted after a preset interval. Or it can be set to perform one or more cleaning operations on the liquid food preparation equipment after a preset working time, and so on.

[0077] When the cleaning command is triggered, it is first necessary to confirm whether the liquid food preparation equipment is in the dispensing state. Specifically, it is necessary to confirm whether the relative positions of the medicine outlet 111, weighing channel 311, and brewing inlet 412 are properly arranged. For example, the positions of the medicine outlet 111, weighing channel 311, and brewing inlet 412 can be adjusted by driving the movement of the medicine storage chamber 110, the container body 310, and / or the brewing cylinder 410.

[0078] It should be noted that, optionally, the following may also be included before step S100: Step F100: Issue a prompt message to empty the slag box and detect changes in the status of the slag box; Step F200: After confirming that the slag box has been reset from the in-position state to the out-of-position state, proceed with the subsequent operations.

[0079] It is understandable that by confirming that the waste in the slag box has been emptied and ensuring that the slag box is in place, sufficient space can be reserved in the slag box to collect the waste generated during the cleaning operation of the liquid food preparation equipment.

[0080] Step S200: When the reagent outlet 111, weighing channel 311 and brewing inlet 412 are arranged in sequence along the direction of gravity, control the reagent outlet 111, weighing channel 311 and brewing inlet 412 to keep them connected.

[0081] It is understandable that once the relative positions of the reagent outlet 111, weighing channel 311, and brewing inlet 412 are confirmed to be in place, it is necessary to ensure that the reagent outlet 111, weighing channel 311, and brewing inlet 412 remain connected, that is, to control the opening of the reagent outlet 111, the connection of the weighing channel 311, and the opening of the brewing inlet 412. Specifically, step S200 may include: Step S210: When the reagent outlet 111, weighing channel 311 and brewing inlet 412 are arranged in sequence along the direction of gravity, the reagent outlet 111 is opened and the weighing channel 311 is opened, the drive mechanism is controlled to drive the first piston 420 to move into the brewing chamber 411 to close the brewing opening 413, and the second piston 430 is driven to move outward from the brewing inlet 412 to open the brewing inlet 412.

[0082] Next, following step S210 above, the method further includes: Step S220: Control the drive mechanism to drive the second piston 430 to move until the brewing inlet 412 is closed; Step S230: Control the second solenoid valve 830 to open the liquid inlet pipe 820 and start the second pump body to run; Step S240: After the liquid entering the brewing chamber 411 reaches the first preset water volume threshold, control the second solenoid valve 830 to disconnect the liquid inlet pipe 820 and control the second pump body to stop running.

[0083] In this embodiment, after the medicine is introduced into the brewing chamber 411 as described above, the brewing inlet 412 is further closed by driving the second piston 430, so that the first piston 420 and the second piston 430 together form a closed cleaning chamber in the brewing chamber 411. Then, by controlling the second solenoid valve 830 and the second pump, hot or cold water from the water storage container 810 can be introduced into the cleaning chamber. Preferably, hot water from the water storage container 810 is introduced into the cleaning chamber and maintained for a first time, so that the hot water can fully dissolve the medicine. The specific value of the first time is not limited, for example, it can be about 30 seconds. The amount of hot water introduced into the cleaning chamber can be specifically controlled by the running time of the second solenoid valve 830 and the second pump. The first preset water volume threshold can be the amount of water when the liquid is just enough to fully clean the chamber, or the amount of water when the liquid is enough to dissolve the medicine.

[0084] Next, after step S240, the method further includes: Step S250: After a first duration, control the first solenoid valve to open the liquid outlet line 710; Step S260: Control the first pump body to run intermittently for a first preset number of times and then stop running.

[0085] In this embodiment, after the agent has fully dissolved in the cleaning chamber, a cleaning solution is formed within the cleaning chamber. By controlling the operation of the first solenoid valve and the first pump, the cleaning solution in the cleaning chamber can be connected to the outlet pipe 710 to clean the outlet pipe 710. The intermittent operation of the first pump allows the cleaning solution to clean the outlet pipe 710 in batches multiple times. The interval between each rinse can be specifically set to 30 seconds, and the number of repetitions of the intermittent operation can be designed to be no less than 5 times.

[0086] It should be noted that, before and / or after step S210, the cleaning method for the liquid food preparation equipment also includes a cleaning operation of the brewing tank 410. Specifically, the number of repetitions of the cleaning operation of the brewing tank 410 performed before step S210 is a second preset number; the number of repetitions of the cleaning operation of the brewing tank 410 performed after step S210 is a third preset number. The second and third preset numbers can be set to the same number or different numbers. In one specific application, the second and third preset numbers are set to the same number, specifically no less than 8 times.

[0087] The specific method for cleaning the brewing tank 410 described above is not limited. For example, in one embodiment, the cleaning operation of the brewing tank 410 includes: Step K100: Control the drive mechanism to drive both the first piston 420 and the second piston 430 to move into the brewing chamber 411; Step K200: Control the second solenoid valve 830 to open the liquid inlet pipe 820 and start the second pump body; Step K300: After the liquid entering the brewing chamber 411 reaches the second preset water volume threshold, control the second solenoid valve 830 to disconnect the liquid inlet pipe 820 and control the second pump body to stop running. Step K400: Control the drive mechanism to drive the second piston 430 to move outward from the brewing inlet 412 to open the brewing inlet 412; Step K500: Control the drive mechanism to drive the first piston 420 toward the brewing inlet 412 to push the liquid in the brewing chamber 411 outward.

[0088] In this embodiment, when both the first piston 420 and the second piston 430 are moved into the brewing chamber 411, a relatively closed cleaning chamber can be defined within the brewing chamber 411, as described above. This cleaning chamber may be the same as or different from the one described above. Then, by controlling the second solenoid valve 830 and the second pump, liquid from the water storage container 810 can be introduced into the cleaning chamber. Generally, the cleaning chamber is filled with liquid, so that the liquid in the cleaning chamber can fully wet the piston head of the first piston 420, the piston head of the second piston 430, and the inner wall of the brewing chamber 411. Next, by driving the second piston 430 to move out, the cleaning chamber can be opened and repositioned. By driving the first piston 420 to move towards the brewing inlet 412, the liquid can be driven to approach the brewing inlet 412 to clean the inner wall of the brewing chamber 411. Then, when the first piston 420 moves to the brewing inlet 412, it can completely push the liquid in the brewing chamber 411 outward, and the pushed-out liquid will flow outward along the outer wall of the brewing tank 410 into the residue box. This can not only completely discharge the waste liquid in the brewing chamber 411, but also clean the outer wall of the brewing tank 410.

[0089] The above-mentioned cleaning operation of the brewing tank 410 may also include: Step J100: Control the drive mechanism to drive the first piston 420 to close the brewing opening 413, and control the second piston 430 to close the brewing inlet 412; Step J200: Control the first solenoid valve to isolate the liquid outlet pipeline 710 and stop the first pump body from running; Step J300: Control the second solenoid valve 830 to open the liquid inlet pipe 820 and start the second pump body; Step J400: After the liquid introduced into the brewing chamber 411 fills the sealed chamber between the first piston 420 and the second piston 430, the second solenoid valve 830 is controlled to cut off the liquid inlet pipe 820 and the second pump body is controlled to stop running. Step J500: Control the first solenoid valve to open the liquid outlet line 710, and control the first piston 420 and the second piston 430 to move closer to each other and then further apart. Step J600: Control the drive mechanism to drive the second piston 430 to move outward from the brewing inlet 412 to open the brewing inlet 412; Step J700: Control the drive mechanism to drive the first piston 420 toward the brewing inlet 412 to push the liquid in the brewing chamber 411 outward.

[0090] In this embodiment, the outer peripheral sidewalls of the first piston 420 and the second piston 430 are sealed against the sidewall of the brewing chamber 411. This allows the first piston 420 and the second piston 430 to jointly enclose and define the cleaning chamber located between the two pistons when both are positioned within the brewing chamber 411. When the first solenoid valve activates the liquid outlet pipe 710, the liquid outlet pipe 710 is connected to the cleaning chamber. Then, by manipulating the first piston 420 and the second piston 430 to move closer or further away, residual liquid remaining in the brewing chamber 411 and / or the liquid outlet pipe 710 can be concentrated and drawn into the brewing chamber 411. This facilitates timely recovery and treatment of the residual liquid, effectively preventing deterioration, contamination, and pipe blockage caused by prolonged residual liquid retention. Furthermore, it is characterized by its simple operation. Similarly, when the first piston 420 moves to the brewing inlet 412, it can completely push the liquid in the brewing chamber 411 outward, and the pushed-out liquid will flow outward along the outer wall of the brewing tank 410 into the residue box. This can not only completely discharge the waste liquid in the brewing chamber 411, but also clean the outer wall of the brewing tank 410.

[0091] Based on the above, in the steps of controlling the first solenoid valve to open the liquid outlet pipe 710 and controlling the first piston 420 and the second piston 430 to move closer and further apart, the volume change in the brewing chamber 411 caused by the first piston 420 and the second piston 430 moving closer and further apart is not less than the volume of the liquid outlet pipe 710. Specifically, the product of the translational distance of the first piston 420 and the second piston 430 and the maximum end area of ​​their piston heads is R1, and the total volume of the pipe section connected by the liquid outlet pipe 710 and the brewing chamber 411 is R2. Therefore, R1 is not less than R2. Since R2 and the maximum end area of ​​the piston heads in R1 are fixed, the translational distance of the first piston 420 and the second piston 430 can be adjusted to achieve the above objective. In this way, it can be ensured that the residual liquid in the liquid outlet pipe 710 can be fully drawn out and cleaned in a timely manner.

[0092] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
