[0025] Please see Figs. 1-3 The embodiments of this utility model include:

[0026] A beverage system with residue removal function, mainly used in coffee machines or other beverage machines, includes a raw material storage unit 1, a power or beverage making function unit 2, a beverage outlet unit 3, a main control unit 4, a multi-way control valve 5, a reversing valve 6, and a negative pressure drainage assembly 7. The power or beverage making function unit 2 is connected to the raw material storage unit 1 for pumping beverage raw materials or making beverages. The beverage outlet unit 3 is connected to the power or beverage making function unit 2 via a beverage pipeline 8 for discharging beverages. The beverage pipeline 8 upstream / before the beverage outlet unit 3 is partially or entirely recessed to form a bend 81. The bottom of the bend 81 is connected to the multi-way control valve 5, which includes a first port 51, a second port 52, and a third port 53. The first port and the second port... Connected to the beverage pipeline 8, the third port 53 is connected to the negative pressure drainage assembly 7. The negative pressure drainage assembly 7 includes a power component 71 and a venturi tube 72. The power component 71 is connected to the venturi tube 72 and is used to supply air to the venturi tube 72 to generate negative pressure inside the venturi tube 72. The main control unit 4 is electrically connected to the raw material storage unit 1, the power or beverage making function unit 2, the multi-way control valve 5, and the power component 71, respectively. Under the control of the main control unit 4, the multi-way control valve 5 can block or open the third port 53. When the multi-way control valve 5 opens the third port 53 and connects to the negative pressure drainage assembly 7, the power component 71 is activated, so that the residue in the beverage pipeline 8 is discharged out through the venturi tube 72 under the action of negative pressure, thereby ensuring the consistency of the beverage flavor.

[0027] Furthermore, the raw material storage unit 1 includes a hopper and / or a refrigerator. The hopper may include a powder hopper for holding solid beverage raw materials such as coconut milk powder, orange juice powder, soy milk powder, milk powder, coffee powder, and syrup. It may also include a bean hopper connected to a grinder, such as a coffee bean hopper. The refrigerator is mainly used to hold milk or other liquid beverage raw materials.

[0028] Furthermore, the power or beverage preparation functional unit 2 includes a water pump for pumping water, a liquid pump for pumping milk or other beverages, a heating unit for generating hot water or steam, and a brewing unit for brewing and extracting coffee bean powder after tamping it into a cake. Optionally, the liquid pump can be a peristaltic pump, a gear pump, a diaphragm pump, etc.

[0029] In some embodiments of this application, the main control unit 4 may be a chip or circuit structure with data processing and storage capabilities, such as an MCU.

[0030] In some embodiments of this application, the beverage pipeline 8 has multiple channels. Each beverage pipeline in the multiple channels 8 is connected to a multi-way control valve 5 between the beverage outlet position 3 and the power or beverage making function unit 2. The third port 53 of each multi-way control valve 5 is connected to a reversing valve 6 through a pipeline. The reversing valve 6 is connected to a venturi tube 72 through a pipeline. The main control unit 4 can control the reversing valve 6 to adjust the conduction of the corresponding pipeline between the multi-way control valve 5 and the venturi tube 72.

[0031] In some embodiments of this application, the bend 81 has a U-shaped, near-U-shaped, or inverted parabolic shape, which causes the beverage pipeline 8 to be recessed in whole or in part to form a bend. The multi-way control 5 is installed at the bottom (lowest point) of the bend 81. This makes it easier for residual liquid in the beverage pipeline between the beverage outlet position 3 and the power or beverage making functional unit 2 to flow to the third port 53 of the multi-way control valve 5 and be completely discharged after the beverage is made and the third port 53 of the multi-way control valve 5 is opened.

[0032] Alternatively, the beverage tubing 8 can be pre-bent into a bend 81, or the beverage tubing 8 can be fixed into a bend 81 using a structure such as wire clips.

[0033] Optionally, the multi-way control valve 5 is located at the lowest (trough) point of the bend section 81.

[0034] Furthermore, the first port 51 of the multi-way control valve 5 is connected to the power or beverage making function unit 2 through the beverage pipeline 8, the second port 52 of the multi-way control valve 5 is connected to the beverage outlet unit 3 through the beverage pipeline 8, and the third port 53 of the multi-way control valve 5 is connected to the reversing valve.

[0035] In some embodiments of this application, the multi-way control valve is a solenoid valve, including a valve body 54, a beverage channel 55 formed when the first port 51 and the second port 52 are connected, a waste discharge channel 56 formed when the first port 51 and the third port 53 are connected and the second port 52 and the third port 53 are connected, a spring 57, a valve core 58, and a solenoid coil 59. The beverage channel 55 and the waste discharge channel 56 are disposed inside the valve body 54. The first port 51 and the second port 52 of the beverage channel 55 are respectively connected to the bend section 81. One end of the waste discharge channel 56 is connected to the beverage channel 55. The third port 53 outside the waste discharge channel 56 is directly or through a pipeline connected to the reversing valve 6. The valve core 58 is disposed inside the waste discharge channel 56 by the spring 57. The solenoid coil 59 is wound around the valve body 54 on the outer periphery of the waste discharge channel 56, and the solenoid coil 59 is magnetically connected to the spring 57 to drive the valve core 58 to extend and retract, thereby blocking or opening the waste discharge channel 56.

[0036] Specifically, when the solenoid valve 5 is energized, the valve core 58 inside the solenoid valve 5 is attracted downward under the action of the electromagnetic field to block the third port 53, so that the fluid during beverage preparation can only flow from the first port 51 to the second port 52, and finally be output from the beverage outlet unit 3; when the solenoid valve 5 is de-energized, the valve core 58 inside the solenoid valve 5 loses the attraction of the electromagnetic field and is pushed upward by the spring 57 to open the third port 53, so that the residue in the beverage pipeline 8 flows into the third port 53 from the first port 51 and the second port 52 under the action of negative pressure and is discharged.

[0037] Furthermore, the main control unit 4 can control the residual liquid discharge operation according to a preset frequency or time to avoid residual liquid remaining in the pipeline to breed bacteria or deteriorate due to long-term uncleaning, thus affecting the taste and quality of the subsequent beverages.

[0038] In some embodiments of this application, the main control unit 4 can control the corresponding pipeline to start the residue removal operation after one or more beverages have been made.

[0039] In some other embodiments of this application, the main control unit 4 can initiate a residual discharge operation after the beverage device has self-cleaned, so as to drain the liquid in the pipeline.

[0040] Furthermore, the negative pressure drainage assembly 7 also includes a one-way valve 73, and the power unit 71 is connected to the venturi tube 72 through the one-way valve 73 to prevent the backflow of residue.

[0041] In some embodiments of this application, the power component 71 includes an air pump or a high-speed fan for accelerating the gas.

[0042] Furthermore, the venturi tube 72 is connected to the water storage or drainage unit 74, so that the residue is discharged into the water storage or drainage unit 74.

[0043] In some embodiments of this application, the water storage or drainage unit 74 is connected to a sewer pipe.

[0044] In some embodiments of this application, the venturi tube 72 includes an inlet 721, a throat 722, an outlet 723, and a negative pressure port 724. The inlet 721, throat 722, and outlet 723 are connected in sequence. The inlet 721 is connected to the power unit 71. One end of the negative pressure port 724 is connected to the reversing valve 6, and the other end is connected to the throat 722 or the outlet 723 near the throat 722, so that residues enter the venturi tube 72 through the negative pressure port 724. When the power unit 71 supplies air to the venturi tube 72, the airflow through the constricted throat 722 causes an increase in flow velocity and a decrease in pressure, thereby creating a negative pressure at the throat 722 to draw residues into the venturi tube 72 and discharge them through the water storage or drainage unit 74.

[0045] When the beverage equipment is making beverages or cleaning pipelines, the main control unit 4 controls the multi-way control valve 5 to be energized. At this time, the beverage channel 55 is opened and the residue discharge channel 56 is closed to complete the beverage output and the cleaning or dredging of each beverage pipeline. When the beverage equipment finishes making beverages or cleaning pipelines and triggers the residue discharge operation, the main control unit 4 controls the multi-way control valve 5 to be de-energized to open the residue discharge channel 56. The main control unit 4 controls the reversing valve 6 to adjust the connection to the corresponding pipeline. At the same time, the power unit 71 starts working under the control of the main control unit 4 to send air to the venturi tube 72, so that a negative pressure is generated in the venturi tube 72. Under the action of negative pressure, the residue in the beverage pipeline 8 is discharged into the storage or drainage unit 74 after passing through the residue discharge channel 56, the reversing valve 6 and the venturi tube 72. After the residue discharge is completed, the main control unit 4 controls the multi-way control valve 5 to be energized again to block the residue discharge channel 56.

[0046] The beneficial effects of this utility model of a beverage system with residue removal function are: it can quickly and effectively remove residues from the pipelines of beverage equipment, reduce the risk of them mixing into new beverages, ensure the consistency of beverages, improve the taste of beverages and consumer satisfaction, disrupt the growth environment of bacteria, reduce the growth of bacteria, thereby improving food safety, extending the service life of equipment, and has a simple structure and low cost.
