[0052] In the application scenario of the present invention, there are multiple beverage barrels 30, and each beverage barrel 30 can be used to place different beverages or raw materials. The design of the beverage making pipeline 11 corresponding to the chassis 10 is usually also relatively complicated. The multiple beverage barrels 30 are connected one-to-one with the multiple water inlets 10a of the chassis 10, and the multiple water outlets 10b of the chassis 10 are not connected to the wastewater tank or the wastewater collection barrel. By adopting the above-mentioned technical solution, the complexity of cleaning the beverage machine can be reduced. The beverage barrel 30 can be connected to the multiple water inlets 10a of the chassis 10 through a multi-head first connecting pipe 21, and the multiple water outlets 10b of the chassis 10 can be connected to the wastewater tank or the wastewater collection barrel through a multi-head second connecting pipe 22, which can greatly improve the convenience of cleaning operation.

[0053] The beverage machine in this embodiment can be based on the Android system, and a specific application can be installed to realize partial automation of the beverage machine cleaning through the application, which can greatly improve its cleaning and disinfection efficiency and effect. The control board of the circuit assembly 40 can be a bottom RA3288 control circuit board, etc., and the motor valve 41 can be a stepper motor, etc., which is not limited here.

[0054] In the technical solution of the present invention, the beverage machine includes a chassis 10, a cleaning pipeline 20, a beverage barrel 30 and a circuit assembly 40. The chassis 10 is provided with a beverage making pipeline 11 and a water inlet 10a and a water outlet 10b respectively connected to the beverage making pipeline 11; the cleaning pipeline 20 includes a first connecting pipe 21 and a second connecting pipe 22; the beverage barrel 30 is placed on the chassis 10 and is used to load the cleaning liquid. The beverage barrel 30 is connected to the water inlet 10a of the chassis 10 through the first connecting pipe 21, and the water inlet 10a of the second connecting pipe 22 is connected to the water inlet 10a of the chassis 10.

It can be understood that by using the circuit assembly 40 to adjust the on-off of the beverage making pipeline 11, the cleaning and disinfection operation of the beverage machine is more convenient, the cleaning efficiency and disinfection effect of the beverage machine are improved, and the hygienic safety of its beverage making is improved.

[0055] In order to facilitate the disassembly and assembly of the cleaning pipeline 20, in one embodiment, refer to Figure 1 and Figure 2 The water inlet end of the first connecting pipe 21 and the water outlet end of the beverage barrel 30, the water outlet end of the first connecting pipe 21 and the water inlet 10a of the chassis 10, and the second connecting pipe 22 and the water outlet 10b of the chassis 10 are all detachably connected.

[0056] In this embodiment, the number of the beverage barrels 30 is at least one, and the number of the water inlet 10a and the water outlet 10b of the chassis 10 can be the same as the number of the beverage barrels 30; the water outlet joint of the first connecting pipe 21 is connected to the water inlet 10a of the chassis 10 one-to-one; the water inlet joint of the second connecting pipe 22 is connected to the water outlet 10b of the chassis 10 one-to-one. In this way, when the number of the beverage barrels 30 is multiple and the design of the beverage making pipeline 11 of the chassis 10 is usually more complicated, the above scheme can reduce the complexity of cleaning the beverage machine, and only one (or more) beverage barrels 30 for containing cleaning liquid can be connected to the multiple water inlets 10a of the chassis 10 through a multi-head first connecting pipe 21, and a multi-head second connecting pipe 22 can connect the multiple water outlets 10b of the chassis 10 with the waste water tank or waste water collection bucket, so as to fully soak and rinse all the beverage making pipelines 11 inside the chassis 10, which can greatly improve the convenience of cleaning operation.

[0057] Among them, the first connecting tube 21 and the second connecting tube 22 can both be six-head connecting tubes, that is, the number of beverage barrels 30 can be six, for storing six different beverages respectively, and the number of water inlets 10a and water outlets 10b of the corresponding chassis 10 can also be six, for making six beverages respectively.

[0058] In order to facilitate the discharge of waste liquid generated after cleaning and to further improve the cleaning efficiency, in one embodiment, the cabinet 10 of the beverage machine is also provided with an air outlet connected to the beverage making pipeline 11, and the cleaning pipeline 20 also includes a third connecting pipe, and one end of the third connecting pipe, the water outlet end of the second connecting pipe 22, is connected to the air outlet of the cabinet 10, and the other end of the third connecting pipe is placed in the waste water tank of the cabinet 10 or is suitable for being placed in a waste water collection bucket.

[0059] In one embodiment, if Figure 2 As shown, the circuit component 40 may also include a display screen 42 and / or a voice module.

[0060] In this embodiment, the display screen 42 can be a touch screen, such as LCD, OLED, capacitive touch screen, etc., and the voice module can be a buzzer, a speaker, a smart speaker, etc., which is not limited here.

[0061] It is understandable that when the beverage machine needs to be cleaned and disinfected, the display screen 42 and / or the voice module can output a cleaning signal to remind the staff that the beverage machine needs to be cleaned and disinfected regularly; during the cleaning and disinfection process, the display screen 42 and / or the voice module can output other signals such as soaking and rinsing to remind the staff to continue to complete the disinfection process; after the cleaning and disinfection is completed, the display screen 42 and / or the voice module can output a cleaning success signal to remind the staff that the cleaning and disinfection of the beverage machine has been successfully completed.

[0062] The present invention also provides a method for cleaning a beverage machine, and the method for cleaning the beverage machine is based on the above beverage machine.

[0063] refer to Figure 3 In one embodiment of the present invention, the method for cleaning the beverage machine comprises the following steps:

[0064] S10, connecting the beverage barrel to the water inlet end of the first connecting pipe, and connecting the water outlet end of the first connecting pipe to the water inlet of the chassis;

[0065] S20, connecting the water inlet end of the second connecting pipe to the water outlet of the chassis and placing the water outlet end thereof in a wastewater tank or a wastewater collection bucket of the chassis, connecting the water inlet end of the third connecting pipe to the air outlet of the chassis and placing the water outlet end thereof in the wastewater tank or a wastewater collection bucket of the chassis;

[0066] S30, adding cleaning liquid into the beverage barrel;

[0067] S40, closing the water valve of the second connecting pipe;

[0068] S50, clicking the cleaning button on the display screen to control the motor valve to pass the cleaning liquid into the beverage making pipeline;

[0069] S60: After the cleaning liquid is soaked for a first preset time and the display screen and / or the voice module outputs a soaking completion signal, the water valve of the second connecting pipe is opened to discharge the cleaning waste liquid.

[0070] The cleaning liquid may be detergent, disinfectant, or tap water, and is not limited here. The first preset time is usually 5 minutes, which can be set according to the size of the machine and the complexity of the pipeline, and is not limited here.

[0071] It should be noted that before cleaning the beverage machine, the water outlets of each beverage barrel are directly connected to each water inlet of the chassis or connected through a small section of pipe. In order to ensure that the beverage-making pipelines of the entire chassis can be fully cleaned and disinfected, and convenient to operate, the complexity of cleaning the beverage machine can be reduced by adopting the above-mentioned technical solution. Only one beverage barrel for cleaning liquid can be connected through a multi-head first connecting pipe (no need to fill each beverage barrel with cleaning liquid. Of course, in some application scenarios, in order to disinfect the beverage barrel, the first connecting pipe and the water inlet of the chassis can also be connected through the first connecting head) and multiple water inlets of the chassis. A multi-head second connecting pipe can connect multiple water outlets of the chassis, and the clean wastewater is discharged to the wastewater tank or wastewater collection bucket, so as to fully soak and rinse all the beverage-making pipelines inside the chassis, which can greatly improve the convenience of cleaning operations.

[0072] In this embodiment, the beverage making pipeline may include a liquid pipeline and a gas pipeline, and the gas pipeline may be connected to an external gas source to serve as a driving force for driving the liquid to flow, etc. Among them, the third connecting pipe may be connected to the gas outlet end of the gas pipeline (i.e., the gas outlet of the chassis) to discharge the clean wastewater into the wastewater tank or the wastewater collection barrel.

[0073] In this embodiment, the on / off state, flow rate, pressure and holding time of the beverage making pipeline can be controlled by utilizing the controller. The user can adjust appropriate parameters by operating the display screen or buttons to assist in the cleaning of the beverage machine, which can greatly improve the convenience of cleaning and disinfection.

[0074] During operation, you can click "One-click Disinfection" in the application on the display screen. The application will control the stepper motor through the underlying RA3288 control circuit board to issue the disinfectant water command, and start discharging disinfectant water from the beverage barrel to soak the pipe. After the disinfectant water is discharged, the underlying RA3288 control circuit board returns the information that the disinfectant water has been discharged to the application. The application starts timing, and the beverage machine needs to be soaked in disinfectant water for the first preset time. After the first preset time, the application's voice and pop-up window prompt that the soaking is complete. Open the water valve of the lower connecting pipe of the second connecting pipe at the bottom of the chassis and wait for the disinfectant to drain naturally.

[0075] Further, in order to improve the cleaning and disinfection effect, in one embodiment, after the cleaning liquid is soaked for a preset time and the display screen outputs soaking completion information, the water valve of the second connecting pipe is opened to discharge the cleaning waste liquid, and the method further includes:

[0076] S70, adding cleaning water into the beverage barrel;

[0077] S80, closing the water valve of the second connecting pipe;

[0078] S90, clicking the flush button on the display screen to control the motor valve to introduce flushing water into the beverage making pipeline;

[0079] S100, after the cleaning water is soaked for a second preset time and the display screen and / or the voice module outputs a flushing success signal, the water valve of the second connecting pipe is opened to discharge the cleaning waste liquid.

[0080] In this embodiment, tap water or filtered water or other cleaning water may be used to flush the sterilized beverage making pipeline to clean the beverage machine.

[0081] During operation, you can click "One-key flushing" in the application on the display screen. The application sends a command for first-level water to control the stepper motor through the bottom RA3288 control circuit board to start discharging first-level water from the beverage barrel to flush the pipe. After the first-level water is discharged, the bottom RA3288 control circuit board returns the information that the first-level water has been discharged to the application. The application prompts that the flushing is successful, opens the water valve of the lower connecting pipe of the second connecting pipe at the bottom of the chassis, and waits for the water to drain naturally.

[0082] Furthermore, in some embodiments, the above-mentioned flushing steps may be repeated to flush the beverage machine twice or multiple times to avoid residual disinfectant in the beverage making pipeline.

[0083] After the second flush is completed, click "One-click Preparation" in the application. The application will send the emptying instruction through the underlying RA3288 control circuit board to control the stepper motor to empty the remaining liquid in the tube.

[0084] In addition, by setting up an application to manage beverage preparation and disinfection, the application can be used to control the equipment so that it cannot make beverages without disinfection, ensuring the sanitation of the equipment when it is used for production. The disinfection status of each device can be monitored in the back-end operating system, and an early warning will be issued when the store equipment is not disinfected. This ensures that when automated equipment is promoted on a large scale, the disinfection status of each device can be monitored.

[0085] Furthermore, in order to facilitate the discharge of the cleaning waste liquid in the gas pipeline of the beverage making pipeline, in one embodiment, before the step of connecting the beverage barrel to the water inlet end of the first connecting pipe and connecting the water outlet end of the first connecting pipe to the water inlet of the chassis, it also includes:

[0086] S01, disassembling the connecting pipes between each of the beverage barrels and the water inlet of the chassis;

[0087] In this embodiment, in order to perform normal drink making operation after cleaning is completed, after the water to be cleaned is soaked for a second preset time and the display screen and / or the voice module outputs a flushing success signal, the water valve of the second connecting pipe is opened to discharge the cleaning waste liquid, and the step also includes:

[0088] S110, disassembling the first connecting pipe, the second connecting pipe, and the third connecting pipe;

[0089] S120, connecting each of the beverage barrels to the water inlet of the chassis.

[0090] In this embodiment, after the flushing process is completed, the first connecting pipe, the second connecting pipe and the third connecting pipe of the cleaning pipeline need to be removed respectively, and then the water outlet of each beverage barrel is directly connected one-to-one with the water inlet of the chassis or connected through a connecting pipe to restore the beverage machine to a normal beverage making state.

[0091] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
