[0047] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0048] In the related art, traditional fully automatic coffee machines typically use two methods to handle the situation when the bean hopper is insufficient for a full cup of coffee. The first is to stop grinding and discard the ground coffee, resulting in wasted coffee beans. The second is to continue brewing coffee using the small amount of ground coffee, which results in reduced coffee quality. Both of these methods result in wasted coffee beans or reduced coffee quality due to insufficient coffee beans.

[0049] In one embodiment, Figure 1 As shown, a coffee machine is provided, including a bean grinding assembly 110, a bean storage assembly 120, a brewing assembly 130 and a control assembly 140, wherein the bean grinding assembly 110 is connected to the bean storage assembly 120, the bean grinding assembly 110 is connected to the brewing assembly 130, and the control assembly 140 is connected to the grinding assembly 110 and the brewing assembly 130 respectively.

[0050] In this embodiment, the bean storage assembly 120 includes a bean storage box for sealed storage of coffee beans. In some embodiments, the bean storage assembly 120 also includes a one-way exhaust valve and a bean level sensor. The one-way exhaust valve is built into the lid, allowing the beans to exhale CO2 while blocking oxygen from entering. The bean level sensor can use a photoelectric or weighing sensor to monitor the remaining coffee bean level in real time. The bean level sensor is connected to the control assembly 140, which displays a reminder to replenish beans.

[0051] The bean grinding assembly 110 includes a grinding disc, a drive unit, a bearing and other structures. The bean grinding assembly 110 is used to grind the coffee beans to a set particle size. The brewing assembly 130 includes a hot water system, a powder cake system and an extraction unit. The brewing assembly 130 is used to complete the entire coffee extraction process. Among them, the hot water system can achieve precise temperature control of 92-96 degrees Celsius (℃). The powder cake system includes an electronic weighing platform and a pre-infusion system. The electronic weighing platform can accurately measure the amount of coffee powder. The pre-infusion system can slowly inject water under low pressure (3 bar) to complete the expansion of the powder cake. It should be noted that this embodiment does not limit the specific structure of the bean grinding assembly 110 and the brewing assembly 130, and can be determined according to the type of coffee machine in the actual application scenario.

[0052] In this embodiment, the bean grinding assembly 110 is directly connected to the bean storage box and can rotate at the same speed at the same grinding degree to ensure that the coffee powder ground per unit time remains consistent. The ground coffee powder will be further pushed into the brewing assembly 130.

[0053] In this embodiment, if Figure 2 As shown, the control component 140 includes a processor 141, a current monitoring unit 142, a display unit 143 and a touch unit 144. The processor 141 is connected to the current monitoring unit 142, the display unit 143 and the touch unit 144 respectively. In some embodiments, the display unit 143 and the touch unit 144 can be integrated into a touch display unit 143. The current monitoring unit 142 includes a current sensor for monitoring the working current of the grinding component 110. The processor 141 is used to receive and analyze data from the current sensor. The display unit 143 is used to display and prompt relevant information. The touch unit 144 is used to provide operation buttons, and the user can configure the extraction parameters, grinding parameters and various production parameters of the coffee machine by operating the touch unit 144. It should be noted that the actual structure of the control component 140 can be configured accordingly according to the needs of the actual application scenario, and is not limited here.

[0054] In one embodiment, Figure 3 As shown, a coffee machine extraction control method is provided, which is applied to Figure 1 The control component in the example is used to illustrate the following steps:

[0055] S301, monitoring the operating current of the bean grinding assembly.

[0056] In this embodiment, a current monitoring unit is configured inside the bean grinding assembly to continuously monitor the operating current of the bean grinding assembly during operation, and further determine the bean storage status in the bean storage assembly based on the operating current.

[0057] It should be noted that the actual type and location of the current monitoring unit can be configured in the drive circuit of the grinding assembly according to the needs of the actual application scenario. For example, by installing a current monitoring sensor in the drive circuit of the grinding assembly and electrically connecting the current monitoring sensor to the processor, the operating current of the grinding assembly can be monitored in real time.

[0058] In this embodiment, the operating current of the grinding assembly can be monitored after the coffee machine is started. Alternatively, the operating current of the grinding assembly can be monitored when the user operates the coffee machine to begin brewing a beverage. The timing at which the processor, through the current monitoring unit, begins monitoring the operating current of the grinding assembly can be adaptively configured based on the needs of the actual application scenario.

[0059] S302: If the operating current of the bean grinding assembly is continuously greater than or equal to the preset current threshold, the bean grinding assembly is controlled to continue operating for the first time until one grinding is completed, and the brewing assembly is controlled to complete coffee liquid extraction according to the first extraction parameter.

[0060] In this embodiment, during a beverage making process, the bean grinding assembly starts grinding beans at the first moment. The beverage making process refers to the process of making coffee concentrate. In actual application, the types of coffee that can be made by a fully automatic coffee machine include espresso, Americano, latte, mocha, etc. This embodiment does not limit the types of beverages that can be made by the coffee machine, and the type of beverage can be determined based on the actual type of coffee machine in the actual application scenario. The first moment refers to the time point when the bean grinding assembly starts working. For example, the user starts making coffee by operating the touch unit of the coffee machine at 18:23, and the bean grinding assembly starts grinding beans at this time, then the first moment is 18:23. In some feasible embodiments, the bean grinding assembly can also be started after the coffee machine completes operations such as boiler preheating. In this case, the first moment can be 18:24. It should be noted that the specific time point of the first moment can be configured according to the needs of the actual application scenario.

[0061] In this embodiment, the preset current threshold can be set to any value from 0.1A to 10A. This embodiment does not limit the actual value of the preset current threshold, and it can be configured according to the needs of the actual application scenario.

[0062] In this embodiment, when the working current of the bean grinding component is continuously greater than or equal to the preset current threshold, the bean grinding component is controlled to continue working until one bean grinding process is completed. In actual application, the bean powder amount of the coffee powder in the powder cake making component can be monitored. When the bean powder amount in the powder cake making component is greater than or equal to the preset bean powder amount threshold, it is determined that the bean grinding process is completed. It should be noted that the device for monitoring the bean powder amount of the coffee powder in the powder cake making component can be configured according to the needs of the actual application scenario. In actual application, the amount of bean powder produced by the bean grinding component is linearly related to the working time of the bean grinding component. The bean grinding component will produce the amount of bean powder to complete one bean grinding process when it continues to work for the first time. At this time, the powder cake making component can make a complete powder cake or a standard powder cake. At this time, the brewing component is controlled to complete coffee extraction according to the first extraction parameter, that is, the standard extraction parameter.

[0063] In this embodiment, the first time refers to the time required for the grinding assembly to complete a single grinding process. Extraction parameters include water temperature, pressure, and extraction time. The water temperature is controlled by the coffee machine's hot water system. In practice, the extraction water temperature should be controlled between 80°C and 100°C. In some preferred embodiments, the extraction water temperature should be controlled between 91°C and 93°C. The extraction pressure should be controlled between 8 bar and 10 bar. The extraction time should be controlled between 5 seconds and 40 seconds. In some preferred embodiments, the extraction time should be controlled between 23 and 27 seconds.

[0064] For example, in this embodiment, the first extraction parameter includes water temperature ,pressure and extraction time .

[0065] In this embodiment, the specific working processes of the bean grinding component and the brewing component can refer to the specific working processes of different coffee machines in actual application scenarios and are not specifically limited here.

[0066] S303: If the operating current of the bean grinding assembly at the second moment is less than the preset current threshold, the bean grinding assembly is controlled to stop grinding beans, and a second time from the first moment to the second moment is recorded.

[0067] In this embodiment, if the grinding assembly's operating current is less than a preset current threshold while the grinding assembly is operating, the instantaneous time at which the grinding assembly's operating current is less than the preset current threshold is recorded to obtain a second moment. At the second moment, the control assembly controls the grinding assembly to stop grinding, and records the second time from the start of grinding (the first moment) to the stop of grinding (the second moment).

[0068] In this embodiment, the operating current of the bean grinding assembly is less than the preset current threshold, indicating that there are no coffee beans remaining in the bean storage assembly and the grinding disc of the bean grinding assembly. At this time, the user needs to be prompted to replenish coffee beans.

[0069] S304, obtaining the coffee bean replenishment status.

[0070] In this embodiment, the coffee bean replenishment status includes replenishing the same type of coffee beans and replenishing different types of coffee beans. The control component can determine the coffee bean replenishment status by interacting with the user.

[0071] In actual application scenarios, a bean quantity sensor is set in the bean storage component. After the user replenishes coffee beans, the bean storage component will sense the newly added coffee beans inside. At this time, the control component will further control the grinding component and brewing component to complete the coffee making according to the coffee bean replenishment situation.

[0072] S305, controlling the bean grinding component to complete the bean grinding process according to the coffee bean replenishment situation, the first time and the second time, and controlling the brewing component to complete the coffee liquid extraction according to the first extraction parameter or the second extraction parameter.

[0073] In this embodiment, the coffee machine will complete the coffee liquid extraction according to different extraction parameters for replenishing the same type of coffee beans and replenishing different types of coffee beans.

[0074] In one embodiment, when the first time is equal to the second time, the first extraction parameter and the second extraction parameter are the same; when the first time is greater than the second time, the water temperature of the second extraction parameter is greater than the water temperature of the first extraction parameter, the pressure of the second extraction parameter is greater than the pressure of the first extraction parameter, and the extraction time of the second extraction parameter is less than the extraction time of the first extraction parameter.

[0075] In this embodiment, when the first time and the second time are equal, it means that the coffee beans in the bean storage component are just enough to make a complete powder cake. At this time, the first extraction parameter and the second extraction parameter are the same parameters, and the coffee bean replenishment situation is not related to the extraction parameter corresponding to the brewing component.

[0076] If the first time and the second time are not equal, it means that the bean grinding assembly is not sufficient to produce a complete coffee cake during the grinding process. In this case, if the coffee bean replenishment determines that direct coffee liquid extraction is required, coffee liquid is extracted according to the second extraction parameters, where the water temperature is greater than the first extraction parameter, the pressure is greater than the first extraction parameter, and the extraction time is less than the first extraction parameter. If the coffee bean replenishment determines that coffee grounds should be replenished first and then coffee liquid is extracted, the bean grinding assembly is controlled to complete the bean grinding process until a complete coffee cake is obtained, and then coffee liquid is extracted according to the first extraction parameters.

[0077] Based on the above steps, this embodiment provides a coffee machine extraction control method. By real-time monitoring of the operating current changes of the bean grinding component, it is determined whether the bean hopper is short of beans, and the current grinding time is automatically recorded. Combined with the compensation mechanism for residual coffee powder in the channel, the method intelligently guides the user to replenish coffee beans or adjust the extraction strategy, thereby achieving efficient utilization of coffee beans and stable output of coffee quality. It effectively solves the problems of resource waste, coffee quality degradation, and insufficient intelligent operation caused by insufficient coffee beans in existing coffee machines, ensuring that high-quality coffee can be produced every time.

[0078] In one embodiment, obtaining the coffee bean replenishment status includes:

[0079] If the control component receives the first bean replenishment signal, it determines that the coffee beans are replenished as the same type of coffee beans; if the control component receives the second bean replenishment signal, it determines that the coffee beans are replenished as different types of coffee beans.

[0080] In this embodiment, when the operating current of the bean grinding assembly is less than a preset current threshold, the control component determines that the bean storage assembly needs to be refilled. At this point, the control component displays a bean refill prompt on the display, and the user can determine whether to refill the same type of coffee beans or a different type of coffee beans by operating the touch control unit. In one feasible embodiment, the control component can also interact with the user through a voice component, confirming the coffee bean refill status by asking the user whether to refill the same type of coffee beans.

[0081] In this embodiment, after the user selects the option to replenish coffee beans of the same type, i.e., operates the touch unit corresponding to the option to replenish coffee beans of the same type, the control component receives a first bean replenishment signal and determines that the coffee beans are replenished as the same type. After the user selects the option to replenish coffee beans of different types, i.e., operates the touch unit corresponding to the option to replenish coffee beans of different types, the control component receives a second bean replenishment signal and determines that the coffee beans are replenished as the different type.

[0082] Based on the above steps, the coffee machine extraction control method provided in this embodiment can interact with the user to determine whether to replenish the same type of coffee beans when monitoring that the bean storage component is out of beans. It can further determine the subsequent bean grinding parameters and extraction parameters based on the user's bean replenishment situation to ensure the quality of coffee production and avoid coffee bean waste.

[0083] In one embodiment, controlling the bean grinding component to complete the bean grinding process according to the coffee bean replenishment status, the first time, and the second time, and controlling the brewing component to complete the coffee liquid extraction according to the first extraction parameter or the second extraction parameter includes:

[0084] If the coffee beans are replenished with the same type of coffee beans, a third time is calculated based on the first time, the second time, and the preset compensation time, the grinding assembly is controlled to continue grinding the beans for the third time to complete the grinding process, and the brewing assembly is controlled to complete the coffee liquid extraction according to the first extraction parameter;

[0085] If the coffee bean replenishment situation is to replenish different types of coffee beans, it is determined that the bean grinding component completes the bean grinding process, and the brewing component is controlled according to the second extraction parameter to complete the coffee liquid extraction.

[0086] In this embodiment, the calculation formula of the third time is:

[0087]

[0088] in, For the third time, For the first time, For the second time, is the preset compensation time. In this embodiment, the preset compensation time .

[0089] In actual application, since the bean grinder may bring the residual coffee powder in the channel into the brewer during idling, the bean grinder assembly in this embodiment will add an extra grinding time. To compensate for this loss, it's important to note that after being ground, the coffee beans may not immediately fall into the brewer. Instead, they pass through a channel. Due to the rotation of the cutter head and the vibration of the machine during idling, the remaining coffee grounds in the channel will fall into the brewer. Since the channel is empty at this time, the coffee grounds in the channel need to be filled before the next round of brewing. Therefore, an additional period of time is required to ensure that there is a sufficient amount of coffee grounds in the brewer during the next round of brewing.

[0090] In this embodiment, if the same type of coffee beans are added, the control component will control the grinding component to continue grinding the beans for a third time to complete the grinding process, produce a complete powder cake, and control the brewing component to complete the coffee liquid extraction according to the first extraction parameter.

[0091] If different types of coffee beans are added, the control component will directly determine that the grinding component has completed the grinding process. At this time, the powder cake in the brewing component is an incomplete powder cake, and the brewing component needs to be controlled according to a second extraction parameter different from the first extraction parameter to complete the coffee liquid extraction.

[0092] In one embodiment, if the coffee bean replenishment condition is replenishing different types of coffee beans, the coffee machine extraction control method further includes:

[0093] The powder amount ratio of the remaining soy powder and the complete powder cake soy powder in the brewing component is calculated based on the first time and the second time; the water temperature increase coefficient, the pressure increase coefficient and the extraction time reduction coefficient are calculated respectively according to the powder amount ratio; the water temperature of the second extraction parameter is calculated based on the water temperature and the water temperature increase coefficient of the first extraction parameter; the water temperature of the second extraction parameter is calculated based on the pressure and the pressure increase coefficient of the first extraction parameter; the extraction time of the second extraction parameter is calculated based on the extraction time of the first extraction parameter and the extraction time reduction coefficient.

[0094] In this embodiment, it is assumed that For the first time, For the second time, the formula for calculating the ratio of the remaining bean powder in the bubble component to the bean powder in the complete powder cake is: It should be noted that, in a feasible embodiment, the ratio of the remaining bean powder in the brewing component to the bean powder in the complete powder cake can also be calculated based on the weight of the bean powder collected by the weighing platform in the brewing component. The weighing platform will record the weight of the complete powder cake and the current weight of the bean powder, and the aforementioned powder ratio is calculated based on the ratio of the current weight of the bean powder to the weight of the complete powder cake.

[0095] In this embodiment, the water temperature increase coefficient, the pressure increase coefficient and the extraction time reduction coefficient are calculated respectively according to the powder amount ratio. Combined with the water temperature, pressure and extraction time of the first extraction parameter, the water temperature, pressure and extraction time of the second extraction parameter can be adaptively calculated, thereby realizing adaptive adjustment of the extraction parameters according to the powder amount ratio to ensure the extraction quality of each extraction by the coffee machine.

[0096] In one embodiment, determining the water temperature of the second extraction parameter according to the water temperature of the first extraction parameter and the water temperature increase coefficient includes:

[0097]

[0098] in, The water temperature is the second extraction parameter, The water temperature is the first extraction parameter, is the empirical value of water temperature change, For the second time, For the first time.

[0099] Based on the above steps, when the amount of powder is reduced, appropriately increasing the water temperature can enhance the extraction efficiency. It can usually be set to 2-3℃, which means that for every 10% reduction in powder amount, the water temperature will increase by 2-3℃.

[0100] Determining the pressure of the second extraction parameter according to the pressure of the first extraction parameter and the pressure increase coefficient includes:

[0101]

[0102] in, is the pressure of the second extraction parameter, is the pressure of the first extraction parameter, is the empirical value of pressure change, For the second time, For the first time.

[0103] Based on the above steps, when the amount of powder decreases, appropriately increasing the extraction pressure helps improve the extraction efficiency. It can usually be set to 0.1-0.2, which means that for every 10% reduction in powder volume, the pressure increases by 10%-20%.

[0104] Determining the extraction time of the second extraction parameter according to the extraction time of the first extraction parameter and the extraction time reduction coefficient includes:

[0105]

[0106] in, For the third time, is the empirical value of extraction time change, For the second time, For the first time.

[0107] Based on the above steps, when the powder amount is insufficient, in order to ensure the extraction rate, the extraction time needs to be shortened appropriately. For example, if the current powder amount is only 50% of the ideal powder amount ( ), the extraction time should be shortened to 0.5 times the original time.

[0108] Based on the above steps, the extraction parameters can be adaptively adjusted according to the powder ratio to ensure the quality of coffee.

[0109] In one embodiment, the coffee machine extraction control method further includes:

[0110] Obtain a beverage preparation type; determine a first moment and a first time according to the beverage preparation type; determine an amount of complete powder cake bean powder according to the first time; and determine a first extraction parameter according to the amount of complete powder cake bean powder and a reference extraction parameter.

[0111] In this embodiment, the drink types include espresso, double espresso, Americano, latte, and mocha. The first moment and first time for each drink type can be the same or different, and can be configured based on the needs of the actual application scenario. The first time corresponds to the amount of soy powder in a complete powder cake.

[0112] In actual applications, the standard powder cake bean powder amount corresponds to the reference extraction parameter. When the whole powder cake bean powder amount corresponding to the current beverage preparation type is the same as the standard powder cake bean powder amount, the first extraction parameter and the reference extraction parameter are the same. If the whole powder cake bean powder amount corresponding to the current beverage preparation type is different from the standard powder cake bean powder amount, the reference extraction parameter can be adjusted accordingly according to the adjustment logic of the first and second extraction parameters to obtain the first extraction parameter.

[0113] In summary, this embodiment provides a coffee machine extraction control method, which provides current monitoring and bean shortage judgment logic. After the bean grinding component is started, the current sensor monitors the working current in real time. When the current is less than the preset current threshold, it is determined to be lacking beans, and the bean grinding is stopped immediately and the current bean grinding time is recorded. The user is prompted by the display to choose whether to change the coffee bean variety; if not, after adding coffee beans of the same variety, the bean grinding component continues to grind the beans for a third time, and the third time takes into account the grinding compensation time to ensure the complete amount of powder cake; if replaced, the extraction parameters are adjusted based on the proportion of the remaining powder. In the bean changing scenario, the coffee quality is guaranteed by adaptively adjusting the combined strategy of water temperature, pressure, and extraction time.

[0115] Based on the same inventive concept, embodiments of the present application also provide a coffee machine extraction control device for implementing the aforementioned coffee machine extraction control method. The solution provided by this device is similar to the solution described in the aforementioned method. Therefore, the specific limitations of one or more coffee machine extraction control device embodiments provided below can be found in the aforementioned limitations of the coffee machine extraction control method and will not be further elaborated here.

[0116] In one embodiment, Figure 4 As shown, a coffee machine extraction control device 400 is provided, comprising: a current monitoring module 410, a first control module 420 and a second control module 430, wherein:

[0117] The current monitoring module 410 is used to monitor the operating current of the bean grinding assembly;

[0118] The first control module 420 is configured to control the grinding assembly to start grinding beans at a first moment during a beverage preparation process, and if the operating current of the grinding assembly is continuously greater than or equal to a preset current threshold, control the grinding assembly to continue operating for a first time period until the grinding is completed, and control the brewing assembly to complete coffee liquid extraction according to the first extraction parameter;

[0119] The second control module 430 is configured to control the bean grinding assembly to stop grinding beans and record a second time from the first moment to the second moment if the operating current of the bean grinding assembly at the second moment is less than a preset current threshold; obtain a coffee bean replenishment status; control the bean grinding assembly to complete the bean grinding process according to the coffee bean replenishment status, the first time, and the second time, and control the brewing assembly to complete the coffee liquid extraction according to the first extraction parameter or the second extraction parameter.
