[0003] The present invention aims to solve at least one of the technical problems of difficult washing of the beer machine after brewing in the prior art.

[0004] To this end, a first aspect of the present invention provides a washing method for a beer machine.

[0005] A second aspect of the present invention provides a washing device for a beer machine.

[0006] A third aspect of the present invention provides a washing device for a beer machine.

[0007] A fourth aspect of the present invention provides a readable storage medium.

[0008] A fifth aspect of the present invention provides a beer machine.

[0009] In view of this, according to the first aspect of the present invention, a washing method for a beer machine is provided. The beer machine includes a fermentation system, a washing system and a drainage system connected to the fermentation system, and also includes a valve assembly for controlling the connection relationship between the fermentation system, the washing system and the drainage system. The washing method for the beer machine includes: in response to a cleaning input, controlling the valve assembly to operate: connecting the washing system and the fermentation system, and cutting off between the drainage system and the fermentation system; controlling the washing system to work for the first time; after the first operation of the washing system is completed, controlling the valve assembly to operate: connecting the drainage system and the fermentation system; controlling the drainage system to work for the first time; after the first operation of the drainage system is completed, controlling the valve assembly to operate, keeping the washing system and the fermentation system connected, and keeping the drainage system and the fermentation system connected; controlling the washing system to work for the second time and controlling the drainage system to work for the second time.

[0010] The washing method of the beer machine proposed by the present invention is applied to a beer machine. The beer machine includes a fermentation system, a washing system, and a drainage system. Among them, the washing system is connected to the fermentation system and can transport liquid into the fermentation system. The drainage system is connected to the fermentation system and can discharge the gas and liquid in the fermentation system. A valve assembly is provided between one or several of the fermentation system, the washing system, and the drainage system. Specifically, the valve assembly includes a plurality of valve bodies, which are respectively arranged between different components, so as to control different connection states between the fermentation system, the washing system, and the drainage system.

[0011] The washing method of the beer machine specifically includes: after receiving the input for washing the beer machine, controlling the valve assembly to work, and the valve bodies in the valve assembly act, so that the washing system and the fermentation system are connected to each other, and the drainage system and the fermentation system are cut off. Furthermore, the washing system can only wash the fermentation system and cannot wash the drainage system.

[0012] After that, control the washing system to work for the first time and transport a cleaning medium into the fermentation system. Since the fermentation system cannot discharge gas and liquid through the drainage system, the inside of the fermentation system can be washed for the first time. Since the cleaning medium entering the fermentation system cannot be discharged, whether it is liquid cleaning medium or gas cleaning medium, it will stay in the fermentation system for a certain period of time, so as to play a role in softening the residual substances and making the residual substances easier to detach from the fermentation system.

[0013] After controlling the washing system to work for the first time and transporting the liquid into the fermentation system, control the valve assembly to work, and the valve bodies in the valve assembly act, so that the drainage system and the fermentation system are connected to each other, and the washing system and the fermentation system are connected to each other.

[0014] After that, control the drainage system to work for the first time and discharge the liquid or gas in the fermentation system from the fermentation system. Furthermore, part or all of the residual substances are discharged from the beer machine through the drainage system.

[0015] After controlling the drainage system to work for the first time and discharging the liquid or gas in the fermentation system from the fermentation system, keep the valve assembly so that the washing system and the fermentation system remain connected to each other, and the drainage system and the fermentation system remain connected to each other.

[0016] After that, control the washing system to work for the second time and infuse a washing medium into the fermentation system, and at the same time control the drainage system to work for the second time and discharge the washing medium in the fermentation system, so as to form a flowing washing state to completely flush out the residual substances from the fermentation system.

[0017] As described above, the washing method of the beer machine proposed by the present invention performs two cleanings on the fermentation system. The first is a closed washing, which can soak or infiltrate the residual substances, making the residual substances soften and easier to separate from the fermentation system. The second is a flowing washing. After the washing medium that enters the fermentation system through the washing system washes the fermentation system, it directly discharges from the drainage system, thereby reducing the residence time of the residual substances in the fermentation system and improving the washing effect.

[0018] In addition, according to the washing method of the beer machine provided by the above technical solution of the present invention, the following additional technical features may also be included:

[0019] Based on the above technical solution, further, the beer machine further includes an air injection system, which is connected to the fermentation system, and the valve assembly is also used to control the connection relationship between the fermentation system and the air injection system. The washing method of the beer machine further includes: after the second operation of the washing system and the drainage system is completed, controlling the air injection system to operate.

[0020] In this technical solution, the beer machine further includes an air injection system connected to the fermentation system, and the valve assembly is used to control the connection relationship between the fermentation system, the air injection system, the washing system, and the drainage system. Specifically, the valve assembly includes a plurality of valve bodies, which are respectively arranged between different components, so as to control different connection states between the fermentation system, the air injection system, the washing system, and the drainage system.

[0021] After the second operation of the washing system and the drainage system to complete the second cleaning of the fermentation system, control the air injection system to operate, and send air flow to the fermentation system, thereby drying the washing substances in the fermentation system, reducing the humidity in the fermentation system, making the fermentation system keep dry, and being conducive to the long-term storage of the beer machine.

[0022] Based on any of the above technical solutions, further, the beer machine further includes an exhaust system, which is connected to the fermentation system. The step of controlling the air injection system to operate after the second operation of the washing system and the drainage system is completed specifically includes: after the second operation of the washing system and the drainage system is completed, controlling the exhaust system to open and controlling the valve assembly to operate: connecting the air injection system and the fermentation system, and cutting off between the drainage system and the fermentation system; controlling the air injection system to operate.

[0023] In this technical solution, the beer machine further includes an exhaust system connected to the fermentation system. After the washing system and the liquid drainage system work for the second time and complete the operation of cleaning the fermentation system for the second time, the step of controlling the air injection system to work and deliver air flow to the fermentation system specifically includes: after the washing system and the liquid drainage system work for the second time and complete the operation of cleaning the fermentation system for the second time, controlling the exhaust system to open, so that the gas in the fermentation system can be discharged through the exhaust system, and controlling the valve assembly to work, and the valve body in the valve assembly acts, so that the fermentation system and the air injection system are connected to each other, and the liquid drainage system and the fermentation system are cut off from each other.

[0024] After that, control the air injection system to work and deliver air flow to the fermentation system. Moreover, the air flow in the fermentation system is discharged through the exhaust system, so that the moisture in the fermentation system can be taken away.

[0025] Moreover, during the fermentation process, the exhaust system can discharge the gas in the fermentation system, so as to adjust the pressure in the fermentation system. Therefore, by discharging the gas in the fermentation system through the exhaust system, the exhaust system can be dried, and further it is more convenient for the storage of the beer machine.

[0026] On the basis of any of the above technical solutions, further, after the washing system and the liquid drainage system complete the second work, the step of controlling the air injection system to work specifically further includes: after the air injection system works for the first preset duration, controlling the exhaust system to close, and controlling the valve assembly to work: connecting the air injection system and the fermentation system, and connecting the liquid drainage system and the fermentation system; controlling the liquid drainage system to open; controlling the air injection system to continue to work.

[0027] In this technical solution, after the washing system and the liquid drainage system work for the second time and complete the operation of cleaning the fermentation system for the second time, the step of controlling the air injection system to work and deliver air flow to the fermentation system specifically further includes: after the duration of controlling the air injection system to work and deliver air flow to the fermentation system reaches the first preset duration, controlling the exhaust system to close, and controlling the valve assembly to work, and the valve body in the valve assembly acts, so that the air injection system and the fermentation system are connected to each other, and the liquid drainage system and the fermentation system are also connected to each other. Furthermore, the air flow in the fermentation system cannot be discharged through the exhaust system and can only be discharged through the liquid drainage system.

[0028] After that, control the liquid drainage system to open and discharge the air flow in the fermentation system.

[0029] Also control the air injection system to continue to work and continuously deliver air flow to the fermentation system.

[0030] Moreover, the liquid drainage system can discharge the liquid in the fermentation system. Furthermore, the liquid drainage system will also come into contact with the liquid in the fermentation system. Therefore, by discharging the gas in the fermentation system through the liquid drainage system, the liquid drainage system can be dried, and further it is more convenient for the storage of the beer machine.

[0031] On the basis of any of the above technical solutions, further, the beer machine further includes a liquid discharge and cleaning flow path, one end of which is connected to the gas injection system and the other end is connected to the liquid discharge system. The valve assembly is further used to control the on and off of the liquid discharge and cleaning flow path. After the second operation of the washing system and the liquid discharge system is completed, the steps of controlling the operation of the gas injection system specifically further include: after the gas injection system operates for a second preset duration, controlling the valve assembly to operate: cutting off between the gas injection system and the fermentation system, cutting off between the liquid discharge system and the fermentation system, cutting off between the washing system and the fermentation system, and making the liquid discharge and cleaning flow path conductive; controlling the liquid discharge system to remain open; controlling the gas injection system to continue operating; after the gas injection system operates for a third preset duration, controlling the gas injection system to close, controlling the liquid discharge system to close, and controlling the valve assembly to operate: cutting off between the gas injection system and the fermentation system, cutting off between the liquid discharge system and the fermentation system, cutting off between the washing system and the fermentation system, and cutting off the liquid discharge and cleaning flow path.

[0032] In this technical solution, the beer machine further includes a liquid discharge and cleaning flow path connected to the gas injection system at one end and to the liquid discharge system at the other end, and the valve assembly can also control the on or off of the cleaning pipeline.

[0033] After the second operation of the washing system and the liquid discharge system to complete the second cleaning of the fermentation system, the steps of controlling the gas injection system to operate and deliver air flow to the fermentation system specifically further include: after the duration of the gas injection system operating and delivering air flow to the fermentation system reaches the second preset duration, controlling the valve assembly to operate, and the valve body in the valve assembly acts, so that the gas injection system and the fermentation are cut off from each other, the liquid discharge system and the fermentation system are cut off from each other, the washing system and the fermentation system are cut off from each other, and the liquid discharge and cleaning flow path is made conductive, so that the air flow delivered by the gas injection system can only flow to the liquid discharge system through the liquid discharge and cleaning flow path.

[0034] After that, control the liquid discharge system to remain open to discharge the air flow in the liquid discharge and cleaning flow path, control the gas injection system to continue operating, and continuously deliver air flow to the liquid discharge and cleaning flow path.

[0035] After the operating duration of the gas injection system reaches the third preset duration, control the gas injection system to close, control the liquid discharge system to close, and control the valve assembly to operate. The valve body in the valve assembly acts, so that the liquid discharge system and the fermentation system are cut off from each other, the gas injection system and the fermentation system are cut off from each other, the washing system and the fermentation system are cut off from each other, and the liquid discharge and cleaning flow path is cut off, thereby completing the cleaning of the beer machine and making the fermentation system completely enclosed, which is conducive to the storage of beer.

[0036] Based on any of the above technical solutions, further, the fermentation system includes a storage box and a fermentation tank. Both the storage box and the fermentation tank are connected to the washing system. The storage box is connected to the fermentation tank, and the fermentation tank is connected to the liquid discharge system. The valve assembly is specifically used to control the connection relationship among the storage box, the fermentation tank, the washing system, and the liquid discharge system. In response to a cleaning input, the valve assembly operates: to connect the washing system and the fermentation system, and to cut off the connection between the liquid discharge system and the fermentation system. The specific steps include: in response to a cleaning input, the valve assembly operates: to connect the fermentation tank and the washing system, to cut off the connection between the storage box and the washing system, and to cut off the connection between the liquid discharge system and the fermentation tank.

[0037] In this technical solution, the fermentation system includes a storage box and a fermentation tank. The storage box is connected to the washing system, and the fermentation tank is connected to the washing system. The storage box is connected to the fermentation tank, and the fermentation tank is connected to the liquid discharge component. Specifically, during brewing, some raw materials can be placed in the fermentation tank first, and some raw materials can be placed in the storage box. After fermentation for a certain period of time, some raw materials in the storage box and some raw materials in the fermentation tank are mixed for further fermentation. Among them, the valve assembly is used to control the connection and cut-off between the liquid discharge system and the fermentation tank, and is also used to control the connection and cut-off between the washing system and the fermentation tank, and is also used to control the conduction and cut-off between the washing system and the storage box.

[0038] Specifically, after receiving an input for washing the beer machine, the valve assembly operates, and the valve body in the valve assembly moves, so that the washing system and the fermentation system are connected to each other, and the specific steps for cutting off the connection between the liquid discharge system and the fermentation system include: after receiving an input for washing the beer machine, the valve assembly operates, and the valve body in the valve assembly moves, so that the fermentation tank and the washing system are connected to each other, the connection between the storage box and the fermentation system is cut off, and the connection between the liquid discharge system and the fermentation system is cut off. Thus, during the first washing of the washing system, only the fermentation tank is washed. Since the fermentation process takes place in the fermentation tank, the difficulty of cleaning the fermentation tank is greater than that of other components of the beer machine. Therefore, soaking the residual substances in the fermentation tank for a certain period of time for softening treatment can improve the cleaning effect of the fermentation tank and make the cleaning of the entire beer machine more thorough.

[0039] Based on any of the above technical solutions, further, the washing system includes a steam generator and a liquid injection component. One end of the steam generator is connected to the liquid injection component, and the other end is connected to the fermentation system. The specific steps for controlling the first operation of the washing system include: controlling the liquid injection component to deliver liquid to the steam generator for the first time; controlling the steam generator to operate for the first time.

[0040] In this technical solution, the washing system includes a steam generator and a fermentation liquid injection component connected to the steam generator. Specifically, one end of the steam generator is connected to the liquid injection component, and the other end is connected to the fermentation system. Furthermore, the steps for controlling the first operation of the washing system specifically include: controlling the liquid injection component to supply liquid to the steam generator for the first time. After that, controlling the steam generator to operate for the first time, thereby delivering steam to the fermentation system. The high-temperature steam can promote the softening of the residual substances in the fermentation system, making the residual substances in the fermentation system easier to clean.

[0041] Based on any of the above technical solutions, further, the steps for controlling the first operation of the steam generator specifically include: monitoring the flow rate of the liquid supplied by the liquid injection component to the steam generator for the first time; after the flow rate of the liquid supplied by the liquid injection component for the first time meets the first preset flow rate range, controlling the steam generator to operate for the first time.

[0042] In this technical solution, the steps for controlling the first operation of the steam generator to deliver steam to the fermentation system specifically include: while the liquid injection component supplies liquid to the steam generator, monitoring the liquid injection component to obtain the flow rate of the liquid supplied by the liquid injection component to the steam generator. After the flow rate of the liquid supplied reaches the first preset flow rate, controlling the steam generator to operate for the first time and deliver steam to the fermentation system.

[0043] Specifically, since the heating of the steam generator requires a certain amount of water, if the amount of liquid in the steam generator is too small, there is a risk of dry burning. Therefore, in the present invention, starting the steam generator after the amount of liquid in the steam generator reaches a certain level can reduce the risk of dry burning of the steam generator.

[0044] Based on any of the above technical solutions, further, the beer machine further includes a temperature sensor for detecting the temperature of the steam output by the steam generator. The steps for controlling the first operation of the steam generator specifically further include: obtaining the detection result of the temperature sensor; starting the first timing after the temperature of the steam output by the steam generator is greater than or equal to the first preset temperature; controlling the steam generator to stop the first operation and controlling the liquid injection component to stop the first operation after the duration of the first timing is greater than or equal to the fourth preset duration.

[0045] In this technical solution, the beer machine further includes a temperature sensor, which can detect the temperature of the steam output by the steam generator. Further, the step of the steam generator delivering steam to the fermentation system for the first time specifically includes: obtaining the detection result of the steam temperature by the temperature sensor; after the temperature of the steam delivered by the steam generator is greater than the first preset temperature, starting the first timing; and after the duration of the first timing is greater than or equal to the fourth preset duration, controlling the steam generator to stop working for the first time and controlling the liquid injection component to stop working. Since it is necessary to use high-temperature steam to soften and clean the residual substances in the fermentation system, therefore, only when the temperature of the steam is greater than or equal to the first preset temperature can a better cleaning effect be achieved. Therefore, starting the first timing after the temperature of the steam is greater than or equal to the first preset temperature can achieve better cleaning.

[0046] Based on any of the above technical solutions, further, the step of controlling the washing system to work for the second time specifically includes: obtaining the detection result of the temperature sensor; starting the second timing after the temperature of the steam output by the steam generator is greater than or equal to the second preset temperature; and after the duration of the second timing is greater than or equal to the fifth preset duration, controlling the steam generator to stop working for the second time.

[0047] In this technical solution, the beer machine further includes a temperature sensor, which can detect the temperature of the steam output by the steam generator. Further, the step of the steam generator delivering steam to the fermentation system for the second time specifically includes: obtaining the detection result of the steam temperature by the temperature sensor; after the temperature of the steam delivered by the steam generator is greater than the second preset temperature, starting the second timing; and after the duration of the second timing is greater than or equal to the fifth preset duration, controlling the steam generator to stop working for the second time. Since it is necessary to use high-temperature steam to soften and clean the residual substances in the fermentation system, therefore, only when the temperature of the steam is greater than or equal to the second preset temperature can a better cleaning effect be achieved. Therefore, starting the second timing after the temperature of the steam is greater than or equal to the second preset temperature can achieve better cleaning.

[0048] Based on any of the above technical solutions, further, the step of controlling the washing system to work for the second time specifically further includes: after controlling the steam generator to stop working for the second time, starting the third timing; and after the duration of the third timing is greater than or equal to the sixth preset duration, controlling the liquid injection component to stop working.

[0049] In this technical solution, the steps of controlling the washing system to work for the second time specifically further include: after controlling the steam generator to stop delivering steam to the fermentation system for the second time, a third timing is performed, and the liquid injection component continues to work to deliver liquid to the fermentation system, thereby flushing the fermentation system. Moreover, since the fermentation system is connected to the liquid discharge system, a flowing water flushing effect can be achieved, and the residual substances in the fermentation system can be flushed out of the beer machine, thereby improving the washing effect on the beer machine. Also, after the flushing duration of the liquid injection component for the fermentation system and the liquid discharge system reaches the sixth preset duration, the liquid injection component is controlled to stop working and no longer deliver liquid to the fermentation system.

[0050] Based on any of the above technical solutions, further, before the step of the control valve assembly working to connect the washing system and the fermentation system and cut off between the liquid discharge system and the fermentation system, it further includes: judging whether the fermentation system is closed; based on the situation that the fermentation system is closed, performing the step of the control valve assembly working to connect the washing system and the fermentation system and cut off between the liquid discharge system and the fermentation system.

[0051] In this technical solution, before the step of the control valve assembly working and the valve body in the valve assembly moves to connect the washing system and the fermentation system and cut off between the liquid discharge system and the fermentation system, it further includes: judging whether the fermentation system is in a closed state. Only when the fermentation system is in a closed state, the step of the control valve assembly working and the valve body in the valve assembly moves to connect the washing system and the fermentation system and cut off between the liquid discharge system and the fermentation system is performed. If the fermentation system is open, the washing substances of the washing system will flow outside the fermentation system, thereby affecting the cleaning effect on the fermentation system, and may also cause faults such as short circuits in the beer machine. Therefore, judging whether the fermentation system is closed first and only performing the washing step after the fermentation system is closed can improve the cleaning effect on the beer machine and reduce the possibility of beer machine faults.

[0052] Based on any of the above technical solutions, further, a prompt is issued based on the situation that the fermentation system is not closed.

[0053] In this technical solution, before the step of the control valve assembly working and the valve body in the valve assembly moves to connect the washing system and the fermentation system and cut off between the liquid discharge system and the fermentation system, it further includes: judging whether the fermentation system is in a closed state. If the fermentation system is not in a closed state, a prompt is issued to remind the user that the fermentation system is not closed and the remaining steps are no longer performed.

[0054] On the basis of any of the above technical solutions, further, the liquid discharge system includes a liquid discharge pump. After the first operation of the liquid discharge system is completed, the control valve assembly operates to connect the washing system and the fermentation system, and the steps of connecting the liquid discharge system and the fermentation system specifically include: determining whether the liquid discharge pump is idling; based on the liquid discharge pump idling, the control valve assembly operates to connect the washing system and the fermentation system, and connect the liquid discharge system and the fermentation system.

[0055] In this technical solution, the liquid discharge system includes a liquid discharge pump. After the liquid in the fermentation system is emptied by the liquid discharge system, the control valve assembly operates, and the valve body in the valve assembly moves, so that the washing system and the fermentation system are connected to each other. The steps of connecting the liquid discharge system and the fermentation system specifically include: determining whether the liquid discharge pump is in an idling state. When the liquid discharge pump is in an idling state, it indicates that the liquid in the fermentation system has been emptied. At this time, the liquid discharge pump is closed, and the control valve assembly operates, and the valve body in the valve assembly moves, so that the washing system and the fermentation system are connected to each other, and the liquid discharge system and the fermentation system are connected to each other. Thus, it is possible to detect whether the cleaning liquid in the fermentation system is emptied without adding a sensor to the fermentation system, reducing the manufacturing difficulty and production cost.

[0056] On the basis of any of the above technical solutions, further, after the duration of the first timing is greater than or equal to the fourth preset duration, the steps of controlling the steam generator to stop the first operation and controlling the liquid injection component to stop the first operation specifically include: after the duration of the first timing is greater than or equal to the fourth preset duration, the control valve assembly operates: connecting the storage box and the washing system, connecting the storage box and the fermentation tank, and cutting off the fermentation tank and the liquid discharge system, and then starting the fourth timing; based on the duration of the fourth timing being greater than or equal to the seventh preset duration, controlling the steam generator to stop the first operation and controlling the liquid injection component to stop the first operation.

[0057] In this technical solution, after the duration of the first timing is greater than or equal to the fourth preset duration, the steps of controlling the steam generator to stop the first operation and controlling the liquid injection component to stop the first operation specifically include: after the duration of the first timing is greater than or equal to the fourth preset duration, the control valve assembly operates to connect the storage box and the washing system, connect the storage box and the fermentation tank, and cut off the fermentation tank and the liquid discharge system, and then perform the fourth timing. That is, the steam will stay in the storage box and the fermentation tank, thereby improving the cleaning effect. And, after the duration of the fourth timing is greater than the seventh preset duration, controlling the steam generator to stop the first operation and controlling the liquid injection component to stop the first operation, thereby completing the first operation of the washing system.

[0058] On the basis of any of the above technical solutions, further, the fourth preset duration is greater than the fifth preset duration.

[0059] In this technical solution, the working duration of the steam generator during the first operation of the washing system is greater than that during the second operation of the washing system. Thus, during the first operation, the steam generator mainly softens the dirt so that it can be detached from the beer machine. Therefore, the setting method of making the working duration of the steam generator during the first operation of the washing system greater than that during the second operation of the washing system can make the dirt more easily detached from the beer machine, improving the cleaning effect on the beer machine.

[0060] According to the second aspect of the present invention, a washing device for a beer machine is proposed. The beer machine includes a fermentation system, a washing system and a drainage system connected to the fermentation system, and also includes a valve assembly for controlling the connection relationship between the fermentation system, the washing system and the drainage system. The washing device of the beer machine includes: a first control module for controlling the valve assembly to work in response to a cleaning input, connecting the washing system and the fermentation system and cutting off the connection between the drainage system and the fermentation system; a second control module for controlling the first operation of the washing system; a third control module for controlling the valve assembly to work after the first operation of the washing system is completed, connecting the drainage system and the fermentation system; a fourth control module for controlling the first operation of the drainage system; a fifth control module for controlling the valve assembly to work after the first operation of the drainage system is completed, keeping the washing system and the fermentation system connected and keeping the drainage system and the fermentation system connected; a sixth control module for controlling the second operation of the washing system and controlling the second operation of the drainage system.

[0061] The washing device of the beer machine proposed by the present invention is applied to a beer machine. The beer machine includes a fermentation system, a washing system and a drainage system. Among them, the washing system is connected to the fermentation system and can transport liquid to the fermentation system. The drainage system is connected to the fermentation system and can discharge the gas and liquid in the fermentation system. A valve assembly is provided between one or several of the fermentation system, the washing system and the drainage system. Specifically, the valve assembly includes a plurality of valve bodies respectively arranged between different components, so as to control different connection states between the fermentation system, the washing system and the drainage system.

[0062] After receiving an input for washing the beer machine, the washing device of the beer machine controls the valve assembly to work. The valve bodies in the valve assembly act, making the washing system and the fermentation system connected to each other and cutting off the connection between the drainage system and the fermentation system. Thus, the washing system can only wash the fermentation system and cannot wash the drainage system.

[0063] After that, control the washing system to work for the first time, and convey a cleaning medium into the fermentation system. Since the fermentation system cannot discharge gas and liquid through the liquid discharge system, the inside of the fermentation system can be washed for the first time. Since the cleaning medium entering the fermentation system cannot be discharged, both the liquid cleaning medium and the gas cleaning medium will stay in the fermentation system for a certain period of time, thereby softening the residual substances and making it easier for the residual substances to detach from the fermentation system.

[0064] After controlling the washing system to work for the first time and conveying liquid into the fermentation system, the control valve assembly works, and the valve body in the valve assembly moves, so that the liquid discharge system and the fermentation system are connected to each other, and the washing system and the fermentation system are connected to each other.

[0065] After that, control the liquid discharge system to work for the first time, and discharge the liquid or gas in the fermentation system from the fermentation system. Then, part or all of the residual substances are discharged from the beer machine through the liquid discharge system.

[0066] After controlling the liquid discharge system to work for the first time and discharging the liquid or gas in the fermentation system from the fermentation system, the control valve assembly is maintained, so that the washing system and the fermentation system remain connected to each other, and the liquid discharge system and the fermentation system remain connected to each other.

[0067] After that, control the washing system to work for the second time, convey a washing medium into the fermentation system, and at the same time control the liquid discharge system to work for the second time to discharge the washing medium in the fermentation system, so as to form a flowing washing state to completely wash out the residual substances from the fermentation system.

[0068] As described above, the washing device of the beer machine proposed by the present invention washes the fermentation system twice. The first time is a closed washing, which can soak or infiltrate the residual substances, making the residual substances softer and easier to detach from the fermentation system. The second time is a flowing washing. After the washing medium entering the fermentation system through the washing system washes the fermentation system, it is directly discharged from the fermentation system through the liquid discharge system, thereby reducing the residence time of the residual substances in the fermentation system and improving the washing effect.

[0069] According to the third aspect of the present invention, the present invention proposes a washing device for a beer machine, including: a memory for storing a computer program; a processor for executing the computer program to implement the washing method of the beer machine as proposed in any one of the above technical solutions.

[0070] The washing device of the beer machine proposed by the present invention includes a memory and a processor. When the processor executes the computer program stored on the memory, it can implement the washing method of the beer machine as proposed in any one of the above technical solutions. Therefore, it has all the beneficial effects of the washing method of the beer machine as proposed in any one of the above technical solutions, and will not be elaborated one by one here.

[0071] According to a fourth aspect of the present invention, the present invention provides a readable storage medium, on which a program or instructions are stored, and when the program or instructions are executed by a processor, the steps of the washing method of the beer machine proposed in any one of the above technical solutions are implemented.

Detailed implementation manners

[0098] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0099] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0100] The following refers to Figures 1 to 17 to describe the washing method of the beer machine, the washing device of the beer machine, the readable storage medium and the beer machine 500 provided according to some embodiments of the present invention.

[0101] Embodiment 1:

[0102] Figure 1One of the flowcharts showing the washing method of the beer machine provided by an embodiment of the present invention.

[0103] As Figure 1 shown, the specific process of the washing method of the beer machine provided by the present invention is as follows:

[0104] Step 102: In response to the washing input, the control valve assembly operates: connecting the washing system and the fermentation system, and cutting off between the drainage system and the fermentation system;

[0105] Step 104: Control the washing system to work for the first time;

[0106] Step 106: After the first operation of the washing system is completed, the control valve assembly operates: connecting the drainage system and the fermentation system;

[0107] Step 108: Control the drainage system to work for the first time;

[0108] Step 110: After the first operation of the drainage system is completed, the control valve assembly connects the washing system and the fermentation system, and connects the drainage system and the fermentation system;

[0109] Step 112: Control the washing system to work for the second time and control the drainage system to work for the second time.

[0110] As Figure 6 、 Figure 7 and Figure 8 shown, the washing method of the beer machine provided by the present invention is applied to the beer machine 500. The beer machine 500 includes a fermentation system 510, a washing system 530, and a drainage system. Among them, the fermentation system 510 is connected to the washing system 530, and thus the washing system 530 can transport washing substances, such as water, cleaning liquid, or steam, etc., into the fermentation system 510. The fermentation system 510 is connected to the drainage system, and the drainage system can drain the liquid in the fermentation system 510.

[0111] A valve assembly 690 is provided between one or several of the fermentation system 510, the washing system 530, and the drainage system. Specifically, the valve assembly 690 includes a plurality of valve bodies, which are respectively arranged between different components, so as to control different connection states between the fermentation system 510, the washing system 530, and the drainage system.

[0112] The washing method of the beer machine specifically includes: after receiving the input for washing the beer machine 500, the control valve assembly 690 operates, and the valve bodies in the valve assembly 690 act, so that the washing system 530 and the fermentation system 510 are connected to each other, and the drainage system and the fermentation system 510 are cut off from each other. Thus, the washing system 530 can only wash the fermentation system 510 and cannot wash the drainage system.

[0113] After that, control the washing system 530 to work for the first time, and convey a cleaning medium into the fermentation system 510. Since the fermentation system 510 cannot discharge gas and liquid through the liquid discharge system, the inside of the fermentation system 510 can be washed for the first time. Since the cleaning medium entering the fermentation system 510 cannot be discharged, both the liquid cleaning medium and the gas cleaning medium will stay in the fermentation system 510 for a certain period of time, thereby softening the residual substances and making it easier for the residual substances to separate from the fermentation system 510.

[0114] After controlling the washing system 530 to work for the first time and conveying liquid into the fermentation system 510, the control valve assembly 690 works, and the valve body in the valve assembly 690 moves, so that the liquid discharge system and the fermentation system 510 are connected to each other, and the washing system 530 and the fermentation system 510 are connected to each other.

[0115] After that, control the liquid discharge system to work for the first time, and discharge the liquid or gas in the fermentation system 510 from the fermentation system 510. Then, part or all of the residual substances are discharged from the beer machine 500 through the liquid discharge system.

[0116] After controlling the liquid discharge system to work for the first time and discharging the liquid or gas in the fermentation system 510 from the fermentation system 510, the control valve assembly 690 works, and the valve body in the valve assembly 690 moves, so that the washing system 530 and the fermentation system 510 are connected to each other, and the liquid discharge system and the fermentation system 510 are connected to each other.

[0117] After that, control the washing system 530 to work for the second time, convey a washing medium into the fermentation system 510, and at the same time control the liquid discharge system to work for the second time to discharge the washing medium in the fermentation system 510, so as to form a flowing washing state to completely flush out the residual substances from the fermentation system 510.

[0118] As described above, the washing method of the beer machine proposed by the present invention washes the fermentation system 510 twice. The first time is a closed washing, which can soak or infiltrate the residual substances, making the residual substances softer and easier to separate from the fermentation system 510. The second time is a flowing washing. After the washing medium entering the fermentation system 510 through the washing system 530 washes the fermentation system 510, it is directly discharged from the fermentation system 510 through the liquid discharge system, thereby reducing the residence time of the residual substances in the fermentation system 510 and improving the washing effect.

[0119] Among them, the fermentation system 510, the washing system 530 and the liquid discharge system can be connected through pipelines.

[0120] Specifically, the liquid discharge system includes a first liquid discharge system 560 and a second liquid discharge system 580. Among them, the first liquid discharge system 560 is connected to the peripheral side wall of the fermentation system 510. Further, the first liquid discharge system 560 is connected to the peripheral side wall at the lower part of the fermentation system 510. Since solids will remain after the fermentation of raw materials and the solids will precipitate to the bottom of the fermentation system 510, and then the first liquid discharge system 560 is connected to the peripheral side wall of the fermentation system 510, the clean liquid on the upper layer of the finished product can be obtained, thereby improving the quality of the extracted finished product.

[0121] The first liquid discharge system 560 includes a fourth pipeline 562, a fourth valve body 564, a liquid discharge pump 566 and a liquid discharge member 568. One end of the fourth pipeline 562 is connected to the fermentation system 510, and the other end is connected to the liquid discharge member 568. The fourth valve body 564 is arranged on the fourth pipeline 562 to control the conduction and cut-off of the fourth pipeline 562. The liquid discharge pump 566 is arranged on the fourth pipeline 562. Thus, when the fourth valve body 564 is opened, through the operation of the liquid discharge pump 566, the liquid in the fermentation system 510 can be discharged through the fourth pipeline 562 and the liquid discharge member 568. Furthermore, the liquid discharge pump 566 can discharge the finished product brewed in the fermentation system 510.

[0122] The second liquid discharge system 580 is connected to the bottom of the fermentation system 510. Since solid substances such as yeast will be deposited at the bottom of the fermentation system 510 during the brewing process, the liquid at the bottom of the fermentation system 510 can be discharged through the second liquid discharge system 580. Specifically, the second liquid discharge system 580 includes a first filter member 582, a fifth pipeline 584 and a fifth valve body 586. The fifth pipeline 584 is connected to the first filter member 582. The fifth valve body 586 is arranged on the fifth pipeline 584. The first filter member 582 is arranged at the bottom of the fermentation system 510 to filter the liquid and solids in the fermentation system 510. The filtered liquid is discharged through the fifth pipeline 584, improving the extraction rate of the finished product.

[0123] Moreover, after the fermentation system 510 is cleaned, more liquid is discharged through the flow path of the first liquid discharge system 560, and less water remains at the bottom and is discharged from the second liquid discharge system 580 at the bottom. The first filter member 582 can allow liquid and tiny solids to pass through and can be manually opened to make large deposits fall into the waste box 640.

[0124] Example 2:

[0125] On the basis of Embodiment 1, further, the fermentation system 510 includes a storage box 512 and a fermentation tank 522 connected to the storage box 512. Both the storage box 512 and the fermentation tank 522 are connected to the washing system 530. The storage box 512 is connected to the fermentation tank 522, and the fermentation tank 522 is connected to the drainage system. The valve assembly 690 is specifically used to control the connection relationship between the storage box 512, the fermentation tank 522, the washing system 530, and the drainage system. In response to a cleaning input, the valve assembly 690 operates: to connect the washing system 530 and the fermentation system 510, and to cut off between the drainage system and the fermentation system 510. The specific steps include: in response to a cleaning input, the valve assembly 690 operates: to connect the fermentation tank 522 and the washing system 530, to cut off between the storage box 512 and the washing system 530, and to cut off between the drainage system and the fermentation tank 522.

[0126] In this embodiment, the fermentation system 510 includes a storage box 512 and a fermentation tank 522. The storage box 512 is connected to the washing system 530, and the fermentation tank 522 is connected to the washing system 530. The storage box 512 is connected to the fermentation tank 522, and the fermentation tank 522 is connected to the drainage part 568. Specifically, during brewing, some raw materials can be placed in the fermentation tank 522 first, and some raw materials can be placed in the storage box 512. After fermentation proceeds for a certain period of time, some raw materials in the storage box 512 and some raw materials in the fermentation tank 522 are mixed to carry out further fermentation. Among them, the valve assembly 690 is used to control the connection and cut-off between the drainage system and the fermentation tank 522, and is also used to control the connection and cut-off between the washing system 530 and the fermentation tank 522, and is also used to control the conduction and cut-off between the washing system 530 and the storage box 512.

[0127] Specifically, after receiving an input for washing the beer machine 500, the valve assembly 690 operates, and the valve body in the valve assembly 690 moves, so that the washing system 530 and the fermentation system 510 are connected to each other, and the specific steps for cutting off between the drainage system and the fermentation system 510 include: after receiving an input for washing the beer machine 500, the valve assembly 690 operates, and the valve body in the valve assembly 690 moves, so that the fermentation tank 522 and the washing system 530 are connected to each other, to cut off between the storage box 512 and the fermentation system 510, and to cut off between the drainage system and the fermentation system, so that the first washing of the washing system 530 only washes the fermentation tank 522. Because the fermentation process takes place in the fermentation tank 522, the difficulty of cleaning the fermentation tank 522 is greater than that of other components of the beer machine 500. Therefore, soaking and other softening treatments of the residual substances in the fermentation tank 522 for a certain period of time can improve the cleaning effect of the fermentation tank 522, making the cleaning of the integrated beer machine 500 more thorough.

[0128] Specifically, the fermentation system 510 includes a storage box 512, a first pipeline 514, a first valve body 516, a second pipeline 518, a second valve body 520, a third pipeline 524, a third valve body 526, and a fermentation tank 522. Cavities are formed on both the storage box 512 and the fermentation tank 522.

[0129] One end of the first pipeline 514 is connected to the storage box 512, and the other end is connected to both the fermentation system 510 and the washing system 530. A first valve body 516 is provided on the first pipeline 514. One end of the second pipeline 518 is connected to the storage box 512, and the other end is connected to the first pipeline 514. The second pipeline 518 is in parallel with both the first valve body 516 and the storage box 512. One end of the third pipeline 524 is connected to both the second pipeline 518 and the storage box 512, and the other end is connected to the fermentation tank 522. A third valve body 526 is provided on the third pipeline 524.

[0130] Furthermore, multiple flow paths are formed in the washing system 530. One is from the first pipeline 514 to the storage box 512, the second is from the first pipeline 514 to the storage box 512, then to the third pipeline 524, and then to the fermentation tank 522, and the third is from the second pipeline 518 to the third pipeline 524, and then to the fermentation tank 522.

[0131] And, the liquid discharge system includes a first liquid discharge system 560 and a second liquid discharge system 580. Among them, the first liquid discharge system 560 is connected to the peripheral side wall of the fermentation system 510. Further, the first liquid discharge system 560 is connected to the peripheral side wall at the lower part of the fermentation system 510. Since solids will remain after the fermentation of the raw materials and the solids will precipitate to the bottom of the fermentation system 510, and then the first liquid discharge system 560 is connected to the peripheral side wall of the fermentation system 510, clean liquid on the upper layer of the finished product can be obtained, thereby improving the quality of the taken-out finished product.

[0132] The washing system 530 includes a water tank 536 and a water pump 532. The water tank 536 is used to store liquid, and the water pump 532 can transport the liquid in the water tank 536 to the corresponding components.

[0133] That is to say, the valve assembly 690 includes a first valve body 516, a second valve body 520, a third valve body 526, a fifth valve body 586, and a fourth valve body 564.

[0134] A third one-way valve 636 is provided at the outlet of the storage box 512. The third one-way valve 636 is connected between the storage box 512 and the third pipeline 524. The third one-way valve 636 is conducted in the direction from the storage box 512 to the third pipeline 524. The second pipeline 518 is connected to both ends of the third one-way valve 636 and the first valve body 516.

[0135] Specifically, Figure 11Figure 3 showing the washing method of the beer machine provided by an embodiment of the present invention.

[0136] As Figure 11 shown, the specific process of the washing method of the beer machine provided by the present invention is as follows:

[0137] Step 1102: In response to the input of washing, control the second valve body and the third valve body to open, so that the fermentation tank and the washing system are connected to each other, and control the first valve body to close, so that the storage box and the washing system are cut off from each other;

[0138] Step 1104: Control the water pump to work for the first time;

[0139] Step 1106: After the first operation of the water pump is completed, control the fourth valve body and the fifth valve body to open, so that the liquid discharge system and the fermentation system are connected to each other;

[0140] Step 1108: Control the liquid discharge pump to work for the first time,

[0141] Step 1110: After the first operation of the liquid discharge pump is completed, control the fourth valve body and the fifth valve body to open, so that the liquid discharge system and the fermentation system are connected to each other; control the second valve body and the third valve body to open, so that the washing system and the fermentation tank are connected to each other, and also connect the storage box and the fermentation tank to each other, and control the first valve body to close, so that the washing system and the storage box are cut off from each other;

[0142] Step 1112: Control the water pump to work for the second time and control the liquid discharge pump to work for the second time.

[0143] Embodiment 3:

[0144] On the basis of Embodiment 1 or Embodiment 2, further, the beer machine 500 further includes an air injection system 550, which is connected to the fermentation system 510, and the valve assembly 690 is further used to control the connection relationship between the fermentation system 510 and the air injection system 550. The washing method of the beer machine further includes: after the second operation of the washing system 530 and the liquid discharge system is completed, control the air injection system 550 to work.

[0145] In this embodiment, the beer machine 500 further includes an air injection system 550 connected to the fermentation system 510, and the valve assembly 690 is used to control the connection relationship between the fermentation system 510, the air injection system 550, the washing system 530 and the liquid discharge system. Specifically, the valve assembly 690 includes a plurality of valve bodies, which are respectively arranged between different components, so as to control different connection states between the fermentation system 510, the air injection system 550, the washing system 530 and the liquid discharge system.

[0146] After the second operation of the washing system 530 and the drainage system and the completion of the second cleaning of the fermentation system 510, the gas injection system 550 is controlled to operate to deliver air flow to the fermentation system 510, thereby drying the washing substances in the fermentation system 510, reducing the humidity in the fermentation system 510, keeping the fermentation system 510 dry, and facilitating the long-term storage of the beer machine 500.

[0147] Specifically, as Figure 8 shown, the gas injection system 550 includes a second filter element 552 and an air pump 554, and the second filter element 552 can filter the gas entering the corresponding components.

[0148] Moreover, the gas injection system 550 and the washing system 530 form a flow path and are then connected to the fermentation system 510.

[0149] In addition, the gas injection system 550 can provide the air required for material fermentation in the fermentation system 510.

[0150] Specifically, Figure 12 FIG. 4 shows a flow chart of the washing method of the beer machine provided by an embodiment of the present invention.

[0156] Embodiment 4:

[0157] Figure 2 FIG. 2 shows a flow chart of the washing method of the beer machine provided by an embodiment of the present invention.

[0158] As Figure 2 shown, the specific process of the washing method of the beer machine provided by the present invention is as follows:

[0159] Step 202: In response to a washing input, the control valve assembly operates: connecting the washing system and the fermentation system, and cutting off between the drainage system and the fermentation system;

[0162] Step 208: Control the drainage system to work for the first time;

[0163] Step 210: After the drainage system is completed for the first time, the control valve assembly is operated to connect the washing system with the fermentation system, and the drainage system with the fermentation system;

[0164] Step 212: Control the washing system to work for the second time, and control the drainage system to work for the second time;

[0165] Step 214: After the washing system and the drainage system have completed the second operation, the exhaust system is controlled to open, and the valve assembly is controlled to operate: the gas injection system and the fermentation system are connected, and the drainage system and the fermentation system are cut off;

[0166] Step 216: Control the gas injection system to work;

[0167] Step 218: After the gas injection system works for a first preset time, the exhaust system is controlled to be closed, and the valve assembly is controlled to connect the gas injection system with the fermentation system, and the drainage system with the fermentation system;

[0168] Step 220: Control the drainage system to start;

[0169] Step 222: Control the gas injection system to continue working;

[0170] Step 224: after the gas injection system works for a second preset time, the control valve assembly works to cut off the gas injection system from the fermentation system, cut off the drainage system from the fermentation system, cut off the washing system from the fermentation system, and open the drainage cleaning flow path;

[0171] Step 226: Control the drainage system to remain open;

[0172] Step 228: Control the gas injection system to continue working;

[0173] Step 230: After the gas injection system has worked for the third preset time, the gas injection system is controlled to be closed, the drainage system is controlled to be closed, and the valve assembly is controlled to work: the gas injection system and the fermentation system are cut off, the drainage system and the fermentation system are cut off, the washing system and the fermentation system are cut off, and the drainage cleaning flow path is cut off.

[0174] On the basis of any one of Embodiments 1 to 3, further, as Figure 6 , Figure 7 and Figure 8As shown, the cleaning method of the beer machine provided by the present invention is applied to a beer machine 500, which includes a fermentation system 510, a cleaning system 530, and a drainage system. Among them, the fermentation system 510 is connected to the cleaning system 530, so that the cleaning system 530 can transport cleaning substances, such as water, cleaning liquid, or steam, etc., to the fermentation system 510. The fermentation system 510 is connected to the drainage system, and the drainage system can drain the liquid in the fermentation system 510.

[0175] A valve assembly 690 is provided between one or several of the fermentation system 510, the cleaning system 530, and the drainage system. Specifically, the valve assembly 690 includes a plurality of valve bodies, which are respectively arranged between different components, so as to control different communication states between the fermentation system 510, the cleaning system 530, and the drainage system.

[0176] The cleaning method of the beer machine specifically includes: after receiving an input for cleaning the beer machine 500, controlling the valve assembly 690 to work, and the valve bodies in the valve assembly 690 act, so that the cleaning system 530 and the fermentation system 510 are connected, and the drainage system and the fermentation system 510 are cut off. Then, the cleaning system 530 can only clean the fermentation system 510 and cannot clean the drainage system.

[0177] After that, control the cleaning system 530 to work for the first time, and transport a cleaning medium into the fermentation system 510. Since the fermentation system 510 cannot discharge gas and liquid through the drainage system, the inside of the fermentation system 510 can be cleaned for the first time. Since the cleaning medium entering the fermentation system 510 cannot be discharged, whether it is a liquid cleaning medium or a gas cleaning medium, it will stay in the fermentation system 510 for a certain period of time, so as to soften the residual substances and make the residual substances easier to detach from the fermentation system 510.

[0178] After controlling the cleaning system 530 to work for the first time and transporting the liquid into the fermentation system 510, control the valve assembly 690 to work, and the valve bodies in the valve assembly 690 act, so that the drainage system and the fermentation system 510 are connected, and the cleaning system 530 and the fermentation system 510 are connected.

[0179] After that, control the drainage system to work for the first time, and discharge the liquid or gas in the fermentation system 510 from the fermentation system 510. Then, part or all of the residual substances are discharged from the beer machine 500 through the drainage system.

[0180] After the first operation of the liquid discharge system to discharge the liquid or gas in the fermentation system 510 from the fermentation system 510 is completed, the control valve assembly 690 operates, and the valve body in the valve assembly 690 moves, so that the washing system 530 and the fermentation system 510 are connected to each other, and the liquid discharge system and the fermentation system 510 are connected to each other.

[0181] After that, control the second operation of the washing system 530 to infuse the washing medium into the fermentation system 510, and at the same time control the second operation of the liquid discharge system to discharge the washing medium in the fermentation system 510, so as to form a flowing washing state to thoroughly flush out the residual substances from the fermentation system 510.

[0182] As described above, the washing method of the beer machine proposed by the present invention performs two cleanings on the fermentation system 510. The first is a closed washing, which can soak or infiltrate the residual substances, making the residual substances soften and easier to separate from the fermentation system 510. The second is a flowing washing. After the washing medium entering the fermentation system 510 through the washing system 530 washes the fermentation system 510, it is directly discharged from the fermentation system 510 through the liquid discharge system, thereby reducing the residence time of the residual substances in the fermentation system 510 and improving the washing effect.

[0183] Among them, the fermentation system 510, the washing system 530 and the liquid discharge system can be connected through pipelines.

[0184] Specifically, the liquid discharge system includes a first liquid discharge system 560 and a second liquid discharge system 580. Among them, the first liquid discharge system 560 is connected to the peripheral side wall of the fermentation system 510. Further, the first liquid discharge system 560 is connected to the peripheral side wall of the lower part of the fermentation system 510. Since solids will remain after the fermentation of raw materials and the solids will precipitate to the bottom of the fermentation system 510, and then the first liquid discharge system 560 is connected to the peripheral side wall of the fermentation system 510, clean liquid on the upper layer of the finished product can be obtained, thereby improving the quality of the extracted finished product.

[0185] The first liquid discharge system 560 includes a fourth pipeline 562, a fourth valve body 564, a liquid discharge pump 566 and a liquid discharge member 568. One end of the fourth pipeline 562 is connected to the fermentation system 510, and the other end is connected to the liquid discharge member 568. The fourth valve body 564 is arranged on the fourth pipeline 562 to control the conduction and cut-off of the fourth pipeline 562. The liquid discharge pump 566 is arranged on the fourth pipeline 562. Thus, when the fourth valve body 564 is opened, through the operation of the liquid discharge pump 566, the liquid in the fermentation system 510 can be discharged through the fourth pipeline 562 and the liquid discharge member 568. Furthermore, the liquid discharge pump 566 can discharge the finished product brewed in the fermentation system 510.

[0186] The second liquid discharge system 580 is connected to the bottom of the fermentation system 510. During the brewing process, solid substances such as yeast will be deposited at the bottom of the fermentation system 510. Then, the liquid at the bottom of the fermentation system 510 can be discharged through the second liquid discharge system 580. Specifically, the second liquid discharge system 580 includes a first filter element 582, a fifth pipeline 584, and a fifth valve body 586. The fifth pipeline 584 is connected to the first filter element 582, and the fifth valve body 586 is arranged on the fifth pipeline 584. The first filter element 582 is arranged at the bottom of the fermentation system 510, so that the liquid and solids in the fermentation system 510 can be filtered. The filtered liquid is discharged through the fifth pipeline 584, improving the extraction rate of the finished product.

[0187] Moreover, after the fermentation system 510 is cleaned, more liquid is discharged through the flow path of the first liquid discharge system 560, and less water remains at the bottom and is discharged through the second liquid discharge system 580 from the bottom. The first filter element 582 can allow liquid and tiny solids to pass through and can be manually opened to let large deposits fall into the waste box 640.

[0188] In this embodiment, the beer machine 500 further includes an exhaust system 600 connected to the fermentation system 510. After the washing system 530 and the liquid discharge system work for the second time and the operation of the second cleaning of the fermentation system 510 is completed, controlling the injection gas system 550 to work and the steps of delivering air flow to the fermentation system 510 specifically include: after the washing system 530 and the liquid discharge system work for the second time and the operation of the second cleaning of the fermentation system 510 is completed, controlling the exhaust system 600 to open, so that the gas in the fermentation system 510 can be discharged through the exhaust system 600, and controlling the valve assembly 690 to work. The valve body in the valve assembly 690 acts, so that the fermentation system 510 and the injection gas system 550 are connected to each other, and the liquid discharge system and the fermentation system 510 are cut off from each other.

[0189] Then, control the injection gas system 550 to work and deliver air flow to the fermentation system 510. Moreover, the air flow in the fermentation system 510 is discharged through the exhaust system 600, so that the moisture in the fermentation system 510 can be taken away.

[0190] Moreover, during the fermentation process, the exhaust system 600 can discharge the gas in the fermentation system 510, thereby adjusting the pressure in the fermentation system 510. Therefore, by discharging the gas in the fermentation system 510 through the exhaust system 600, the exhaust system 600 can be dried, and further, it is more convenient to store the beer machine 500.

[0191] In this embodiment, after the washing system 530 and the liquid discharge system work for the second time and the operation of the second cleaning of the fermentation system 510 is completed, controlling the gas injection system 550 to work and deliver air flow to the fermentation system 510 specifically further includes: after the duration of controlling the gas injection system 550 to work and deliver air flow to the fermentation system 510 reaches the first preset duration, controlling the exhaust system 600 to close, and, the control valve assembly 690 works, the valve body in the valve assembly 690 acts, so that the gas injection system 550 and the fermentation system 510 are connected to each other, and also the liquid discharge system and the fermentation system 510 are connected to each other. Furthermore, the air flow in the fermentation system 510 cannot be discharged through the exhaust system 600 and can only be discharged through the liquid discharge system.

[0192] After that, control the liquid discharge system to open and discharge the air flow in the fermentation system 510.

[0193] Also control the gas injection system 550 to continue working and continuously deliver air flow to the fermentation system 510.

[0194] And, the liquid discharge system can discharge the liquid in the fermentation system 510. Furthermore, the liquid discharge system will also come into contact with the liquid in the fermentation system 510. Therefore, discharging the gas in the fermentation system 510 through the liquid discharge system can dry the liquid discharge system, and further facilitate the storage of the beer machine 500.

[0195] In this embodiment, the beer machine 500 further includes a liquid discharge cleaning flow path 572 connected to the gas injection system 550 at one end and to the liquid discharge system at the other end, and the valve assembly 690 can also control the conduction or cut-off of the cleaning pipeline.

[0196] After the washing system 530 and the liquid discharge system work for the second time and the operation of the second cleaning of the fermentation system 510 is completed, controlling the gas injection system 550 to work and deliver air flow to the fermentation system 510 specifically further includes: after the duration of the gas injection system 550 working and delivering air flow to the fermentation system 510 reaches the second preset duration, the control valve assembly 690 works, the valve body in the valve assembly 690 acts, so that the gas injection system 550 and the fermentation are cut off from each other, the liquid discharge system and the fermentation system 510 are cut off from each other, the washing system 530 and the fermentation system 510 are cut off from each other, and the liquid discharge cleaning flow path 572 is conducted, so that the air flow delivered by the gas injection system 550 can only flow to the liquid discharge system through the liquid discharge cleaning flow path 572.

[0197] After that, control the liquid discharge system to remain open, discharge the air flow in the liquid discharge cleaning flow path 572, and control the gas injection system 550 to continue working and continuously deliver air flow to the liquid discharge cleaning flow path 572.

[0198] After the working duration of the gas injection system 550 reaches the third preset duration, control the gas injection system 550 to close, control the liquid drainage system to close, and control the valve assembly 690 to operate. The valve body in the valve assembly 690 acts to cut off between the liquid drainage system and the fermentation system 510, also cut off between the gas injection system 550 and the fermentation system 510, also cut off between the washing system 530 and the fermentation system 510, and also cut off the liquid drainage cleaning flow path 572, thereby completing the cleaning of the beer machine 500, and making the fermentation system 510 completely enclosed, which is conducive to the storage of beer.

[0199] Specifically, as Figure 8 shown, the gas injection system 550 and the washing system 530 form a flow path and then are connected to the fermentation system 510. The beer machine 500 further includes an exhaust system 600, and the exhaust system 600 is connected to the fermentation system 510. Specifically, the fermentation system 510 is connected to the fermentation tank 522, so as to be able to discharge the gas in the fermentation tank 522. Among them, the exhaust system 600 includes an exhaust valve 602. And the beer machine 500 further includes a liquid drainage cleaning flow path 572 connected between the gas injection system 550 and the liquid drainage system. The valve assembly 690 further includes a sixth valve body 574, and the sixth valve body 574 is arranged on the liquid drainage cleaning flow path 572 and can control the on or off of the liquid drainage cleaning flow path 572. Specifically, the second liquid drainage system 580 is connected to the liquid drainage cleaning flow path 572. A fourth one-way valve 638 is also arranged on the liquid drainage cleaning flow path 572, and the fourth one-way valve 638 is arranged between the sixth valve body 574 and the first liquid drainage system 560, and the fourth one-way valve 638 is conducted in the direction from the sixth valve body 574 to the first liquid drainage system 560.

[0200] And, as Figure 8 shown, the exhaust system 600 includes an exhaust pipeline 608, an exhaust valve 602, a pressure sensor 604 and a first safety valve 606. Further, as Figure 9 shown, the controller 700 can detect the air pressure in the fermentation tank 522 through the pressure sensor 604, and then when the air pressure in the fermentation tank 522 is greater than the preset air pressure threshold, control the exhaust valve 602 to open, so as to achieve the effect of balancing the pressure in the fermentation tank 522, and make the pressure in the fermentation tank 522 more suitable for fermentation, improving the success rate of brewing. The exhaust valve 602, the pressure sensor 604 and the first safety valve 606 are all arranged on the exhaust pipeline 608.

[0201] And even if the exhaust valve 602 fails, the first safety valve 606 can also open when the pressure in the fermentation tank 522 is greater than the preset pressure, thereby ensuring the safety of the beer machine 500.

[0202] Specifically, Figure 13The fifth flowchart showing the washing method of the beer machine provided by an embodiment of the present invention.

[0203] As Figure 13 shown, the specific process of the washing method of the beer machine provided by the present invention is as follows:

[0204] Step 1302: In response to the input of washing, control the second valve body and the third valve body to open, so that the fermentation tank and the washing system are connected, and control the first valve body to close, so that the storage box and the washing system are cut off;

[0207] Step 1308: Control the liquid discharge pump to work for the first time;

[0208] Step 1310: After the first operation of the liquid discharge pump is completed, control the fourth valve body and the fifth valve body to open, so that the liquid discharge system and the fermentation system are connected, control the second valve body and the third valve body to open, so that the washing system and the fermentation tank are connected, and also connect the storage box and the fermentation tank, and control the first valve body to close, so that the washing system and the storage box are cut off;

[0209] Step 1312: Control the water pump to work for the second time and control the liquid discharge pump to work for the second time;

[0210] Step 1314: After the second operation of the water pump and the liquid discharge pump is completed, control the exhaust valve to open, and control the first valve body, the second valve body and the third valve body to open, so that the washing system and the fermentation tank are connected, so that the washing system and the storage box are connected, and control the fourth valve body and the fifth valve body to close, so that the fermentation tank and the liquid discharge system are cut off;

[0211] Step 1316: Control the air pump to work;

[0212] Step 1318: After the air pump works for the first preset duration, control the exhaust valve to close, and control the first valve body, the second valve body and the third valve body to open, the fourth valve body and the fifth valve body to open, so that the washing system and the fermentation tank are connected, so that the washing system and the storage box are connected, so that the fermentation tank and the liquid discharge system are connected;

[0216] Step 1326: Control the liquid discharge pump to continue to be turned on;

[0217] Step 1328: Control the gas injection system to continue to work;

[0218] Step 1330: After the air pump works for a third preset duration, control the air pump to close, control the first valve body, the second valve body, the third valve body, the fourth valve body, and the fifth valve body to close, so as to cut off between the washing system and the fermentation tank, cut off between the washing system and the storage box, cut off between the fermentation tank and the liquid discharge system, and control the sixth valve body to open, so as to cut off the liquid discharge cleaning flow path.

[0219] Embodiment 5:

[0220] Based on any one of Embodiments 1 to 4, further, in the washing system 530 including a steam generator 534 and a liquid injection component, one end of the steam generator 534 is connected to the liquid injection component, and the other end is connected to the fermentation system 510. In the step of controlling the first operation of the washing system 530, it specifically includes: controlling the liquid injection component to convey liquid to the steam generator 534 for the first time; controlling the steam generator 534 to work for the first time.

[0221] In this embodiment, the washing system 530 includes a steam generator 534 and a fermentation liquid injection component connected to the steam generator 534. Specifically, one end of the steam generator 534 is connected to the liquid injection component, and the other end is connected to the fermentation system 510. Further, the steps of controlling the first operation of the washing system 530 specifically include: controlling the liquid injection component to inject liquid into the steam generator 534 for the first time, and then controlling the steam generator 534 to work for the first time, so as to convey steam to the fermentation system 510. The high-temperature steam can promote the softening of the residual substances in the fermentation system 510, making the residual substances in the fermentation system 510 easier to clean.

[0222] Specifically, the liquid injection component includes a water pump 532 and a water tank 536. The water pump 532 is connected between the steam generator 534 and the water tank 536, and can pump the water in the water tank 536 into the steam generator 534. Moreover, the water pump 532 can also send water to the fermentation system 510 through the steam generator 534, or directly send water to the fermentation system 510 by the water pump 532.

[0223] Embodiment 6:

[0224] On the basis of Embodiment 5, further, the steps of controlling the first operation of the steam generator 534 specifically include: monitoring the flow rate of the liquid delivered to the steam generator 534 by the liquid injection component for the first time; after the flow rate delivered by the liquid injection component for the first time meets the first preset flow rate range, controlling the first operation of the steam generator 534.

[0225] In this embodiment, the steps of controlling the first operation of the steam generator 534 and delivering steam to the fermentation system 510 specifically include: while the liquid injection component delivers liquid to the steam generator 534, monitoring the liquid injection component to obtain the flow rate of the liquid delivered by the liquid injection component to the steam generator 534. After the flow rate delivered by the liquid injection component reaches the first preset flow rate, controlling the first operation of the steam generator 534 and delivering steam to the fermentation system 510.

[0226] Specifically, since the heating of the steam generator 534 requires a certain amount of water, if the amount of liquid in the steam generator 534 is too small, there is a risk of dry burning. Therefore, in the present invention, starting the steam generator 534 after the amount of liquid in the steam generator 534 reaches a certain level can reduce the risk of dry burning of the steam generator 534.

[0227] Specifically, as Figure 9 shown, the beer machine 500 further includes a flow meter 670, which is arranged on the liquid injection component and is used to detect the flow rate of the liquid output by the liquid injection component.

[0228] Embodiment 7:

[0229] On the basis of Embodiment 5 or Embodiment 6, further, the beer machine 500 further includes a temperature sensor 680, which is used to detect the temperature of the steam output by the steam generator 534. The steps of controlling the first operation of the steam generator 534 specifically further include: obtaining the detection result of the temperature sensor 680; starting the first timing after the temperature of the steam output by the steam generator 534 is greater than or equal to the first preset temperature; after the duration of the first timing is greater than or equal to the fourth preset duration, controlling the steam generator 534 to stop the first operation and controlling the liquid injection component to stop the first operation.

[0230] In this embodiment, the beer machine 500 further includes a temperature sensor 680. The temperature sensor 680 can detect the temperature of the steam output by the steam generator 534. Further, the step of the steam generator 534 first delivering steam to the fermentation system 510 specifically includes: obtaining the detection result of the steam temperature by the temperature sensor 680. After the temperature of the steam delivered by the steam generator 534 is greater than the first preset temperature, a first timing is performed. And, after the duration of the first timing is greater than or equal to the fourth preset duration, control the steam generator 534 to stop working for the first time, and control the liquid injection component to stop working. Since it is necessary to soften and process the residual substances in the fermentation system 510 with high-temperature steam, therefore, only when the temperature of the steam is greater than or equal to the first preset temperature, can there be a better cleaning effect. Therefore, performing the first timing after the temperature of the steam is greater than or equal to the first preset temperature can achieve better cleaning.

[0231] Further, after the duration of the first timing is greater than or equal to the fourth preset duration, the steps of controlling the steam generator to stop working for the first time and controlling the liquid injection component to stop working for the first time specifically include: after the duration of the first timing is greater than or equal to the fourth preset duration, control the valve assembly to work: connect the storage box and the washing system, connect the storage box and the fermentation tank, and cut off the fermentation tank and the drainage system, and then start the fourth timing; based on the duration of the fourth timing being greater than or equal to the seventh preset duration, control the steam generator to stop working for the first time and control the liquid injection component to stop working for the first time.

[0232] In this embodiment, after the duration of the first timing is greater than or equal to the fourth preset duration, the steps of controlling the steam generator to stop working for the first time and controlling the liquid injection component to stop working for the first time specifically include: after the duration of the first timing is greater than or equal to the fourth preset duration, control the valve assembly to work, connect the storage box and the washing system, connect the storage box and the fermentation tank, and cut off the fermentation tank and the drainage system, and then perform the fourth timing. That is, the steam will stay in the storage box and the fermentation tank, thereby improving the cleaning effect. And, after the duration of the fourth timing is greater than the seventh preset duration, control the steam generator to stop working for the first time and control the liquid injection component to stop working for the first time, thereby completing the first operation of the washing system.

[0233] Embodiment 8:

[0234] Based on any one of Embodiments 1 to 7, further, before the step of operating the control valve assembly 690 to connect the washing system 530 and the fermentation system 510 and cut off between the liquid discharge system and the fermentation system 510, it further includes: determining whether the fermentation system 510 is closed; based on the situation that the fermentation system 510 is closed, performing the step of operating the control valve assembly 690 to connect the washing system 530 and the fermentation system 510 and cut off between the liquid discharge system and the fermentation system 510.

[0235] In this embodiment, before the step of operating the control valve assembly 690 and the valve body in the valve assembly 690 acts to connect the washing system 530 and the fermentation system 510 and cut off between the liquid discharge system and the fermentation system 510, it further includes: determining whether the fermentation system 510 is in a closed state. Only when the fermentation system 510 is in a closed state, perform the step of operating the control valve assembly 690 and the valve body in the valve assembly 690 acts to connect the washing system 530 and the fermentation system 510 and cut off between the liquid discharge system and the fermentation system 510. If the fermentation system 510 is open, the washing substances in the washing system 530 will flow outside the fermentation system 510, thus affecting the cleaning effect of the fermentation system 510, and may also cause faults such as a short circuit of the beer machine 500. Therefore, first determine whether the fermentation system 510 is closed, and only after the fermentation system 510 is closed, perform the washing step, which can improve the cleaning effect of the beer machine 500 and reduce the possibility of faults of the beer machine 500.

[0236] Based on the situation that the fermentation system 510 is not closed, issue a prompt.

[0237] In this embodiment, before the step of operating the control valve assembly 690 and the valve body in the valve assembly 690 acts to connect the washing system 530 and the fermentation system 510 and cut off between the liquid discharge system and the fermentation system 510, it further includes: determining whether the fermentation system 510 is in a closed state. If the fermentation system 510 is not in a closed state, issue a prompt to remind the user that the fermentation system 510 is not closed and do not perform the remaining steps.

[0238] Specifically, the beer machine 500 further includes a position sensor 660. Both the fermentation tank 522 and the storage box 512 include a cover 5224. The position sensor 660 can detect the positions of the cover 5224 of the fermentation tank 522 and the cover 5224 of the storage box 512, so as to determine whether the fermentation system 510 is closed.

[0239] Specifically, Figure 14 Show the flowchart of the first washing in the washing method of the beer machine provided by an embodiment of the present invention.

[0240] As Figure 14 shown, the specific process of the first washing in the washing method of the beer machine provided by the present invention is as follows:

[0241] Step 1402: In response to the input of washing, determine whether the covers 5224 of the fermentation tank and the storage box are closed; if the judgment result is yes, execute step 1404, and if the judgment result is no, execute step 1406;

[0242] Step 1404: Control the second valve body and the third valve body to open, so that the fermentation tank and the washing system are connected, control the first valve body to close, so that the storage box and the washing system are cut off, control the fourth valve body and the fifth valve body to close, so that the fermentation tank and the drainage system are cut off, and control the exhaust valve to open;

[0243] Step 1406: Issue a prompt;

[0244] Step 1408: Turn on the water pump;

[0245] Step 1410: Determine whether the flow rate pumped out by the water pump reaches the first preset flow rate range; if the judgment result is yes, execute step 1412, and if the judgment result is no, continue to execute step 1410;

[0246] Step 1412: Control the steam generator to turn on;

[0247] Step 1414: Determine whether the temperature of the steam output by the steam generator reaches the first preset temperature; if the judgment result is yes, execute step 1416, and if the judgment result is no, continue to execute step 1414;

[0248] Step 1416: Start the first timing;

[0249] Step 1418: Determine whether the duration is greater than the fourth preset duration; if the judgment result is yes, execute step 1420, and if the judgment result is no, continue to execute step 1418;

[0250] Step 1420: Control the second valve body to close, so that the direct connection channel between the washing system and the fermentation tank is cut off; control the first valve body and the third valve body to open, so that the storage box and the washing system are connected, and the storage box and the fermentation tank are connected, control the fourth valve body and the fifth valve body to close, so that the fermentation tank and the drainage system are cut off;

[0251] Step 1422: Start the fourth timing;

[0252] Step 1424: Determine whether the duration is greater than the seventh preset duration; if the judgment result is yes, execute step 1426, and if the judgment result is no, continue to execute step 1424;

[0253] Step 1426: Control the steam generator to shut down and control the water pump to shut down.

[0254] Embodiment 9:

[0255] On the basis of any one of Embodiments 1 to 8, further, the liquid discharge system includes a liquid discharge pump 566. After the first operation of the liquid discharge system is completed, the control valve assembly 690 operates to connect the washing system 530 and the fermentation system 510, and to connect the liquid discharge system and the fermentation system 510. The specific steps include: determining whether the liquid discharge pump 566 is idling; based on the fact that the liquid discharge pump 566 is idling, the control valve assembly 690 operates to connect the washing system 530 and the fermentation system 510, and to connect the liquid discharge system and the fermentation system 510.

[0256] In this embodiment, the liquid discharge system includes a liquid discharge pump 566. After the liquid in the fermentation system 510 is emptied by the liquid discharge system, the control valve assembly 690 operates, and the valve body in the valve assembly 690 acts to connect the washing system 530 and the fermentation system 510. The specific steps of connecting the liquid discharge system and the fermentation system 510 include: determining whether the liquid discharge pump 566 is in an idling state. When the liquid discharge pump 566 is in an idling state, it indicates that the liquid in the fermentation system 510 has been emptied. At this time, the liquid discharge pump 566 is turned off, and the control valve assembly 690 is controlled to operate, and the valve body in the valve assembly 690 acts to connect the washing system 530 and the fermentation system 510, and to connect the liquid discharge system and the fermentation system 510. Thus, it is possible to detect whether the cleaning liquid in the fermentation system 510 is emptied without adding a sensor to the fermentation system 510, reducing the manufacturing difficulty and production cost.

[0257] Specifically, the liquid discharge system includes a first liquid discharge system 560 and a second liquid discharge system 580. Among them, the first liquid discharge system 560 is connected to the peripheral side wall of the fermentation system 510. Further, the first liquid discharge system 560 is connected to the peripheral side wall of the lower part of the fermentation system 510. Since solids will remain after the fermentation of raw materials and the solids will precipitate to the bottom of the fermentation system 510, and then the first liquid discharge system 560 is connected to the peripheral side wall of the fermentation system 510, clean liquid on the upper layer of the finished product can be obtained, thereby improving the quality of the taken-out finished product.

[0258] The first liquid discharge system 560 includes a fourth pipeline 562, a fourth valve body 564, a liquid discharge pump 566 and a liquid discharge member 568. One end of the fourth pipeline 562 is connected to the fermentation system 510, and the other end is connected to the liquid discharge member 568. The fourth valve body 564 is arranged on the fourth pipeline 562 to control the on and off of the fourth pipeline 562. The liquid discharge pump 566 is arranged on the fourth pipeline 562. When the fourth valve body 564 is opened, through the operation of the liquid discharge pump 566, the liquid in the fermentation system 510 can be discharged through the fourth pipeline 562 and the liquid discharge member 568. Furthermore, the liquid discharge pump 566 can discharge the finished products brewed in the fermentation system 510.

[0259] The second liquid discharge system 580 is connected to the bottom of the fermentation system 510. During the brewing process, solid substances such as yeast will be deposited at the bottom of the fermentation system 510. Furthermore, the liquid at the bottom of the fermentation system 510 can be discharged through the second liquid discharge system 580. Specifically, the second liquid discharge system 580 includes a first filter member 582, a fifth pipeline 584 and a fifth valve body 586. The fifth pipeline 584 is connected to the first filter member 582. The fifth valve body 586 is arranged on the fifth pipeline 584. The first filter member 582 is arranged at the bottom of the fermentation system 510 to filter the liquid and solids in the fermentation system 510. The filtered liquid is discharged through the fifth pipeline 584, improving the extraction rate of the finished products.

[0260] Moreover, after the fermentation system 510 is cleaned, more liquid is discharged through the flow path of the first liquid discharge system 560, and less water remains at the bottom and is discharged through the second liquid discharge system 580 from the bottom. The first filter member 582 can allow liquid and tiny solids to pass through and can be manually opened to let large deposits fall into the waste box 640.

[0261] Specifically, Figure 15 The flowchart of the first liquid discharge in the washing method of the beer machine provided by an embodiment of the present invention is shown.

[0262] As Figure 15 shown, the specific process of the first liquid discharge in the washing method of the beer machine provided by the present invention is as follows:

[0263] Step 1502: Control the liquid discharge pump to start.

[0264] Step 1504: Determine whether the liquid discharge pump is in an idling state. If the determination result is yes, execute Step 1506. If the determination result is no, continue to execute Step 1504.

[0265] Step 1506: Control the fourth valve body and the fifth valve body to close, so as to cut off between the fermentation system and the liquid discharge system.

[0266] Step 1508: Control the liquid discharge pump to close.

[0267] Example 10:

[0268] On the basis of any one of Examples 1 to 9, further, the steps of controlling the second operation of the washing system 530 specifically include: obtaining the detection result of the temperature sensor 680; starting the second timing after the temperature of the steam output by the steam generator 534 is greater than or equal to the second preset temperature; and controlling the steam generator 534 to stop the second operation after the duration of the second timing is greater than or equal to the fifth preset duration.

[0269] In this embodiment, the beer machine 500 further includes a temperature sensor 680, which can detect the temperature of the steam output by the steam generator 534. Further, in the step of the steam generator 534 delivering steam to the fermentation system 510 for the second time, specifically includes: obtaining the detection result of the steam temperature by the temperature sensor 680, starting the second timing after the temperature of the steam delivered by the steam generator 534 is greater than the second preset temperature, and controlling the steam generator 534 to stop working for the second time after the duration of the second timing is greater than or equal to the fifth preset duration. Since it is necessary to use high-temperature steam to soften the residual substances in the fermentation system 510 for cleaning, therefore, only when the temperature of the steam is greater than or equal to the second preset temperature, can there be a better cleaning effect. Therefore, starting the second timing after the temperature of the steam is greater than or equal to the second preset temperature can achieve better cleaning.

[0270] Further, the working duration of the steam generator in the first operation of the washing system should be greater than the working duration of the steam generator in the second operation of the washing system. Thus, the first operation mainly softens the dirt and makes it separate from the beer machine. Therefore, the setting method that the working duration of the steam generator in the first operation of the washing system is greater than the working duration of the steam generator in the second operation of the washing system can make the dirt more easily separate from the beer machine and improve the cleaning effect of the beer machine.

[0271] Example 11:

[0272] On the basis of any one of Examples 1 to 10, further, the steps of controlling the second operation of the washing system 530 specifically further include: starting the third timing after controlling the steam generator 534 to stop the second operation; and controlling the liquid injection component to stop working after the duration of the third timing is greater than or equal to the sixth preset duration.

[0273] In this embodiment, the steps of controlling the washing system 530 to work for the second time specifically further include: after controlling the steam generator 534 to stop working for the second time and stop delivering steam to the fermentation system 510, a third timing is performed, and the liquid injection component continues to work to deliver liquid to the fermentation system 510, thereby realizing the flushing of the fermentation system 510. Moreover, since the fermentation system 510 is connected to the drainage system, a flowing water flushing effect can be achieved, and the residual substances in the fermentation system 510 can be flushed out of the beer machine 500, thereby improving the washing effect on the beer machine 500. Also, after the flushing duration of the liquid injection component for the fermentation system 510 and the drainage system reaches the sixth preset duration, the liquid injection component is controlled to stop working and no longer deliver liquid to the fermentation system 510.

[0274] Specifically, Figure 16 The flowchart of the second washing and drainage in the washing method of the beer machine provided by an embodiment of the present invention is shown.

[0275] As Figure 16 shown, the specific process of the second washing and drainage in the washing method of the beer machine provided by the present invention is as follows:

[0281] Step 1612: Control the steam generator to start;

[0282] Step 1614: Determine whether the temperature of the steam output by the steam generator reaches the second preset temperature; if the determination result is yes, execute step 1616, and if the determination result is no, continue to execute step 1614;

[0283] Step 1616: Start the second timing;

[0284] Step 1618: Determine whether the duration is greater than a fifth preset duration; if the determination result is yes, execute Step 1620, and if the determination result is no, continue to execute Step 1618;

[0285] Step 1620: Control the steam generator to shut down;

[0286] Step 1622: Start the third timing;

[0287] Step 1624: Determine whether the duration is greater than a sixth preset duration; if the determination result is yes, execute Step 1626, and if the determination result is no, continue to execute Step 1624;

[0291] Step 1632: Control the fourth valve body and the fifth valve body to close, so as to cut off between the fermentation system and the drain system.

Specifically, the valve assembly 690 includes a plurality of valve bodies respectively arranged between different components, so as to control different connection states between the fermentation system 510, the air injection system 550, the washing system 530, and the drain system. After the second operation of the washing system 530 and the drain system to complete the second cleaning of the fermentation system 510, control the air injection system 550 to work, and send air flow to the fermentation system 510, so as to blow dry the washing substances in the fermentation system 510, reduce the humidity in the fermentation system 510, keep the fermentation system 510 dry, and facilitate the long-term storage of the beer machine 500.

[0294] The beer machine 500 further includes an exhaust system 600 connected to the fermentation system 510. After the washing system 530 and the liquid discharge system work for the second time and complete the operation of cleaning the fermentation system 510 for the second time, controlling the gas injection system 550 to work and conveying air flow to the fermentation system 510 specifically includes: after the washing system 530 and the liquid discharge system work for the second time and complete the operation of cleaning the fermentation system 510 for the second time, controlling the exhaust system 600 to open, so that the gas in the fermentation system 510 can be discharged through the exhaust system 600, and controlling the valve assembly 690 to work, the valve body in the valve assembly 690 acts, so that the fermentation system 510 and the gas injection system 550 are connected to each other, and the liquid discharge system and the fermentation system 510 are cut off from each other.

[0295] After that, control the gas injection system 550 to work and convey air flow to the fermentation system 510. Moreover, the air flow in the fermentation system 510 is discharged through the exhaust system 600, so that the moisture in the fermentation system 510 can be taken away.

[0296] Moreover, during the fermentation process, the exhaust system 600 can discharge the gas in the fermentation system 510, thereby adjusting the pressure in the fermentation system 510. Therefore, by discharging the gas in the fermentation system 510 through the exhaust system 600, the exhaust system 600 can be dried, and further it is more convenient to store the beer machine 500.

[0297] After the washing system 530 and the liquid discharge system work for the second time and complete the operation of cleaning the fermentation system 510 for the second time, controlling the gas injection system 550 to work and conveying air flow to the fermentation system 510 specifically further includes: after the duration of controlling the gas injection system 550 to work and conveying air flow to the fermentation system 510 reaches the first preset duration, controlling the exhaust system 600 to close, and controlling the valve assembly 690 to work, the valve body in the valve assembly 690 acts, so that the gas injection system 550 and the fermentation system 510 are connected to each other, and the liquid discharge system and the fermentation system 510 are also connected to each other. Furthermore, the air flow in the fermentation system 510 cannot be discharged through the exhaust system 600 and can only be discharged through the liquid discharge system.

[0298] After that, control the liquid discharge system to open and discharge the air flow in the fermentation system 510.

[0299] Also control the gas injection system 550 to continue working and continuously convey air flow to the fermentation system 510.

[0300] Moreover, the liquid discharge system can discharge the liquid in the fermentation system 510. Furthermore, the liquid discharge system will also come into contact with the liquid in the fermentation system 510. Therefore, by discharging the gas in the fermentation system 510 through the liquid discharge system, the liquid discharge system can be dried, and further it is more convenient to store the beer machine 500.

[0301] The beer machine 500 further includes a liquid discharge cleaning flow path 572 connected to the gas injection system 550 at one end and to the liquid discharge system at the other end. The valve assembly 690 can also control the opening or closing of the cleaning pipeline.

[0302] After the washing system 530 and the liquid discharge system work for the second time and complete the second cleaning operation of the fermentation system 510, the step of controlling the gas injection system 550 to work and deliver air flow to the fermentation system 510 specifically further includes: after the working duration of the gas injection system 550 to deliver air flow to the fermentation system 510 reaches the second preset duration, controlling the valve assembly 690 to work, and the valve body in the valve assembly 690 acts, so that the gas injection system 550 and the fermentation are cut off from each other, the liquid discharge system and the fermentation system 510 are cut off from each other, the washing system 530 and the fermentation system 510 are cut off from each other, and the liquid discharge cleaning flow path 572 is opened, so that the air flow delivered by the gas injection system 550 can only flow to the liquid discharge system through the liquid discharge cleaning flow path 572.

[0303] After that, control the liquid discharge system to remain open, discharge the air flow in the liquid discharge cleaning flow path 572, and control the gas injection system 550 to continue working and continuously deliver air flow to the liquid discharge cleaning flow path 572.

[0305] Specifically, Figure 17 The flowchart of blowing air in the washing method of the beer machine provided by an embodiment of the present invention is shown.

[0306] As Figure 17 shown, the specific process of blowing air in the washing method of the beer machine provided by the present invention is as follows:

[0319] Example 13:

[0320] As Figure 3As shown in the figure, the present invention provides a washing device 300 for a beer machine. The beer machine 500 includes a fermentation system 510, a washing system 530 and a drainage system connected to the fermentation system 510, and further includes a valve assembly 690. The valve assembly 690 is used to control the connection relationship between the fermentation system 510, the washing system 530 and the drainage system. The washing device of the beer machine includes: a first control module 302, which is used to respond to a cleaning input and control the valve assembly 690 to work: connect the washing system 530 and the fermentation system 510, and cut off between the drainage system and the fermentation system 510; a second control module 304, which is used to control the first operation of the washing system 530; a third control module 306, which is used to control the valve assembly 690 to work after the first operation of the washing system 530 is completed: connect the drainage system and the fermentation system 510; a fourth control module 308, which is used to control the first operation of the drainage system; a fifth control module 310, which is used to control the valve assembly 690 to work after the first operation of the drainage system is completed, keep the washing system 530 and the fermentation system 510 connected, and keep the drainage system and the fermentation system 510 connected; a sixth control module 312, which is used to control the second operation of the washing system 530 and control the second operation of the drainage system.

[0321] As Figure 6 , Figure 7 and Figure 8 As shown in the figure, the washing device of the beer machine provided by the present invention is applied to the beer machine 500. The beer machine 500 includes a fermentation system 510, a washing system 530 and a drainage system. Among them, the fermentation system 510 is connected to the washing system 530, and thus the washing system 530 can transport washing substances, such as water, cleaning liquid or steam, etc., into the fermentation system 510. The fermentation system 510 is connected to the drainage system, and the drainage system can drain the liquid in the fermentation system 510.

[0322] A valve assembly 690 is provided between one or several of the fermentation system 510, the washing system 530 and the drainage system. Specifically, the valve assembly 690 includes a plurality of valve bodies, which are respectively arranged between different components, so as to control different connection states between the fermentation system 510, the washing system 530 and the drainage system.

[0323] After receiving an input for washing the beer machine 500, the washing device of the beer machine controls the valve assembly 690 to work, and the valve bodies in the valve assembly 690 act, so that the washing system 530 and the fermentation system 510 are connected to each other, and the drainage system and the fermentation system 510 are cut off from each other. Thus, the washing system 530 can only wash the fermentation system 510 and cannot wash the drainage system.

[0324] After that, control the washing system 530 to work for the first time, and convey a cleaning medium into the fermentation system 510. Since the fermentation system 510 cannot discharge gas and liquid through the liquid discharge system, the inside of the fermentation system 510 can be washed for the first time. Since the cleaning medium entering the fermentation system 510 cannot be discharged, both the liquid cleaning medium and the gas cleaning medium will stay in the fermentation system 510 for a certain period of time, thereby softening the residual substances and making it easier for the residual substances to separate from the fermentation system 510.

[0325] After controlling the washing system 530 to work for the first time and conveying liquid into the fermentation system 510, the control valve assembly 690 works, and the valve body in the valve assembly 690 moves, so that the liquid discharge system and the fermentation system 510 are connected to each other, and the washing system 530 and the fermentation system 510 are connected to each other.

[0326] After that, control the liquid discharge system to work for the first time, and discharge the liquid or gas in the fermentation system 510 from the fermentation system 510. Then, part or all of the residual substances are discharged from the beer machine 500 through the liquid discharge system.

[0327] After controlling the liquid discharge system to work for the first time and discharging the liquid or gas in the fermentation system 510 from the fermentation system 510, the control valve assembly 690 is maintained, so that the washing system 530 and the fermentation system 510 remain connected to each other, and the liquid discharge system and the fermentation system 510 remain connected to each other.

[0328] After that, control the washing system 530 to work for the second time, convey a washing medium into the fermentation system 510, and at the same time control the liquid discharge system to work for the second time to discharge the washing medium in the fermentation system 510, thereby forming a flowing washing state to completely flush out the residual substances from the fermentation system 510.

[0329] As described above, the washing device of the beer machine proposed by the present invention washes the fermentation system 510 twice. The first time is a closed - type washing, which can soak or infiltrate the residual substances, making the residual substances softer and easier to separate from the fermentation system 510. The second time is a flowing - type washing. After the washing medium entering the fermentation system 510 through the washing system 530 washes the fermentation system 510, it is directly discharged from the fermentation system 510 through the liquid discharge system, thereby reducing the residence time of the residual substances in the fermentation system 510 and improving the washing effect.

[0330] Among them, the fermentation system 510, the washing system 530 and the liquid discharge system can be connected through pipelines.

[0331] Specifically, the liquid discharge system includes a first liquid discharge system 560 and a second liquid discharge system 580. Among them, the first liquid discharge system 560 is connected to the peripheral side wall of the fermentation system 510. Further, the first liquid discharge system 560 is connected to the peripheral side wall at the lower part of the fermentation system 510. Since solids will remain after the fermentation of raw materials and the solids will precipitate to the bottom of the fermentation system 510, and then the first liquid discharge system 560 is connected to the peripheral side wall of the fermentation system 510, clean liquid on the upper layer of the finished product can be obtained, thereby improving the quality of the extracted finished product.

[0332] The first liquid discharge system 560 includes a fourth pipeline 562, a fourth valve body 564, a liquid discharge pump 566 and a liquid discharge member 568. One end of the fourth pipeline 562 is connected to the fermentation system 510, and the other end is connected to the liquid discharge member 568. The fourth valve body 564 is arranged on the fourth pipeline 562 to control the conduction and cut-off of the fourth pipeline 562. The liquid discharge pump 566 is arranged on the fourth pipeline 562. Thus, when the fourth valve body 564 is opened, through the operation of the liquid discharge pump 566, the liquid in the fermentation system 510 can be discharged through the fourth pipeline 562 and the liquid discharge member 568. Furthermore, the liquid discharge pump 566 can discharge the finished product brewed in the fermentation system 510.

[0333] The second liquid discharge system 580 is connected to the bottom of the fermentation system 510. During the brewing process, solid substances such as yeast will be deposited at the bottom of the fermentation system 510. Furthermore, the liquid at the bottom of the fermentation system 510 can be discharged through the second liquid discharge system 580. Specifically, the second liquid discharge system 580 includes a first filter member 582, a fifth pipeline 584 and a fifth valve body 586. The fifth pipeline 584 is connected to the first filter member 582. The fifth valve body 586 is arranged on the fifth pipeline 584. The first filter member 582 is arranged at the bottom of the fermentation system 510 to filter the liquid and solids in the fermentation system 510. The filtered liquid is discharged through the fifth pipeline 584, improving the extraction rate of the finished product.

[0334] Moreover, after the fermentation system 510 is cleaned, more liquid is discharged through the flow path of the first liquid discharge system 560, and less water remains at the bottom and is discharged through the second liquid discharge system 580 at the bottom. The first filter member 582 can allow liquid and tiny solids to pass through and can be manually opened to make large deposits fall into the waste box 640.

[0373] Specifically, the fermentation system 510 further includes a heat exchange member 590 disposed on the fermentation tank 522. The heat exchange member 590 can be a semiconductor refrigeration sheet or a heat exchange system.

[0374] Specifically, the heat exchange member 590 includes a refrigeration member 592 and a heating member 594 to adjust the temperature of the fermentation tank 522.

[0375] In this embodiment, the fermentation system 510 further includes a heat exchanger 590 disposed on the fermentation tank 522. The heat exchanger 590 can heat and / or cool the fermentation tank 522 to obtain the temperature required for fermentation, thereby increasing the success rate of brewing.

[0376] Specifically, the heat exchanger 590 can be wound around the circumferential side of the fermentation tank 522.

[0377] Furthermore, the fermentation system 510 further includes a heat preservation member. The heat preservation member is disposed outside the fermentation tank 522 and covers the heat exchanger 590 therein.

[0378] Moreover, the beer machine 500 further includes a second safety valve 620 disposed at one end of the fermentation system 510. Specifically, the second safety valve 620 is connected to the flow path between the gas injection system 550 and the washing system 530. For example, the gas injection system 550 and the washing system 530 are connected by a pipeline, and the second safety valve 620 is connected to the pipeline between the gas injection system 550 and the fermentation system 510.

[0379] The beer machine 500 further includes a second safety valve 620. After the pressure in the fermentation system 510 is greater than the second pressure threshold, the second safety valve 620 opens, and the gas in the fermentation system 510 is discharged through the second safety valve 620, thereby enhancing the safety of the beer machine 500.

[0380] Moreover, when the steam generator 534 is abnormally blocked, it may cause the gas pressure in the pipeline to exceed the second pressure threshold. At this time, the second safety valve 620 will exhaust and relieve pressure, enhancing the safety of the beer machine 500.

[0381] Specifically, as Figure 10 shown, the brewing process flow of the beer machine 500 can be roughly divided into the following steps:

[0382] Step 1002: Sterilize, clean, and dry the fermentation system;

[0383] Step 1004: Put the raw materials into the fermentation system;

[0384] Step 1006: The gas injection system injects gas into the fermentation system to mix the raw materials;

[0385] Step 1008: The heat exchanger adjusts the temperature of the fermentation system to the fermentation temperature;

[0386] Step 1010: The gas injection system injects gas into the fermentation system to supplement the gas for fermentation;

[0387] Step 1012: Put the auxiliary materials in sequence;

[0388] Step 1014: The gas injection system injects gas into the fermentation system to remove the residual liquid;

[0389] Step 1016: Ferment the raw materials in the fermentation system;

[0390] Step 1018: Ripen the raw materials in the fermentation system;

[0391] Step 1020: Fermentation is completed;

[0392] Step 1022: Take out the brewed finished product;

[0393] Step 1024: The washing system and the gas injection system clean the fermentation system.

[0394] Among them, the washing method of the beer machine provided by the present invention is the specific process for executing Step 1024.

[0395] Specifically, first perform operations such as sterilization, cleaning, and drying on the fermentation system 510 and pipelines of the beer machine 500; then, dissolve the dry powder into the fermentation tank 522; the gas injection system 550 injects air into the fermentation tank 522 to achieve uniform mixing of the liquid raw materials; the cooling or heating member 594 adjusts the temperature of the fermentation tank 522 to the temperature required for fermentation; the gas injection system 550 injects air into the fermentation tank 522 again to supplement the oxygen required for fermentation; put the brewing auxiliaries in the storage box 512 in sequence; the gas injection system 550 works to blow off the residual liquid in the pipeline; the raw materials start to ferment; the raw materials start to ripen; the fermentation is completed to obtain the finished product; when needed, the first drainage system 560 or the second drainage system 580 can be opened to take out the finished product, and the finished product can be beer, white wine, fruit wine, soy sauce, vinegar, etc.; then the washing system 530 and the gas injection system 550 perform cleaning and drying operations on the fermentation system 510.

[0396] Specifically, the number of the storage box 512, the first pipeline 514, and the first valve body 516 is one or more. The storage box 512, the first pipeline 514, and the first valve body 516 can be two, three, four, etc. at the same time. Among them, multiple storage boxes 512, first pipelines 514, and first valve bodies 516 can be connected in series or in parallel.

[0397] Specifically, the volumes of different storage boxes 512 can be different. The one with a larger volume can hold the main raw materials, for example: the dry powder of wort concentrate, and the one with a smaller volume can hold yeast, hops, flavoring agents, etc.

[0398] Such as Figure 9As shown, the beer machine 500 also includes a controller 700, which controls the operation of the washing system 530 and the gas injection system 550. Specifically, the specific working process of the washing system 530 and the gas injection system 550 may be that after the beer machine 500 completes brewing, the controller 700 first controls the washing system 530 to clean the fermentation system 510, and then the controller 700 controls the gas injection system 550 to dry the fermentation system 510. In the above steps, the operation of the washing system 530 may be performed once or multiple times, or the operation of the washing system 530 and the gas injection system 550 may be performed once or multiple times in a cycle.

[0399] Furthermore, if Figure 6 and Figure 7 As shown, a first one-way valve 632 is provided between the washing system 530 and the fermentation system 510, and the first one-way valve 632 is connected from the washing system 530 to the fermentation system 510. A second one-way valve 634 is provided between the gas injection system 550 and the fermentation system 510, and the second one-way valve 634 is connected from the gas injection system 550 to the fermentation system 510.

[0400] Specifically, Figure 6 and Figure 7 As shown, the beer machine 500 also includes a display panel 710, which can display information such as brewing parameters.

[0401] like Figure 9 As shown, the controller 700 and the air pressure sensor 604, the exhaust valve 602, the liquid level sensor 650, the position sensor 660, the heating element 594, the flow meter 670, the water pump 532, the displacement pump 566, the temperature sensor 680, the air pump 554, the valve assembly 690 and the refrigeration element 592 are electrically connected, wherein the valve assembly 690 includes a sixth valve body 574, a fifth valve body 586, a first valve body 516, a second valve body 520, a third valve body 526 and a fourth valve body 564.

[0402] Furthermore, the controller 700 can control the exhaust valve 602, the heating element 594, the water pump 532, the drainage pump 566, the air pump 554, the valve assembly 690 and the refrigeration element 592 according to the monitoring results of the air pressure sensor 604, the liquid level sensor 650, the position sensor 660, the flow meter 670 and the temperature sensor 680.

[0403] For example, the fermenter 522 is connected with a first safety valve 606, a pressure sensor 604 and an exhaust valve 602 through pipelines. During the fermentation process, when the gas pressure in the fermenter 522 exceeds the first pressure threshold, the pressure sensor 604 sends the detected signal to the controller 700, and the controller 700 will open the exhaust valve 602 for exhaust. When the exhaust valve 602 fails, the first safety valve 606 can be opened for exhaust to ensure the safety of the beer machine 500.

[0404] For another example, a fourth valve body 564 is provided on the pipeline at the inlet of the liquid discharge pump 566. When beer needs to be discharged, the pressure sensor 604 first detects the internal pressure of the fermenter 522. When the pressure exceeds a certain pressure to open the pressure threshold, for example, 10 kPa, the fourth valve body 564 opens, and the liquid discharge pump 566 does not need to be opened. The liquid can be discharged by relying on the internal pressure of the fermenter 522. When the pressure is less than the opening pressure threshold, the fourth valve body 564 opens, and the liquid discharge pump 566 is opened simultaneously to ensure smooth liquid discharge.
