Technical Field

[0001] This application relates to the field of electrical technology, and in particular to a method and device for identifying the contents of a coffee machine waste container, a coffee machine, and a storage medium. Background Technology

[0002] As people's living standards improve, the use of coffee machines is gradually becoming a market demand. During the use of a coffee machine, a waste container is needed to hold the extracted coffee grounds. To avoid making a mess of the surrounding environment, it is especially important to be able to tell whether the waste container is full.

[0003] In traditional technologies, the identification of coffee machine waste bins is mostly done by installing sensors on the coffee machine. However, sensor identification has limitations. Usually, the waste bin is not full when it is prompted to be emptied, resulting in low space utilization within the waste bin. Summary of the Invention

[0004] Therefore, it is necessary to provide a coffee machine waste bin identification method and device, coffee machine, and storage medium that can improve the utilization rate of the space inside the waste bin, in order to address the above-mentioned technical problems.

[0005] Firstly, this application provides a method for identifying the contents of a coffee machine waste container, including:

[0006] After extraction, pour the powder into the waste container;

[0007] If the powder cake breaks during the pouring process, the volume of the broken powder cake in the waste box is obtained.

[0008] If the powder cake does not break during the pouring process, obtain the complete volume of the powder cake in the waste box;

[0009] Based on the volume of the broken powder compact, the volume of the intact powder compact, and the volume of the waste container, determine whether the waste container is full.

[0010] In one embodiment, the process for determining whether the powder cake breaks during the pouring process includes:

[0011] During the pouring process, the powder cake is judged to be broken based on the filtration time, extraction parameters of the extraction process, and the opening and closing status of the powder pressing switch.

[0012] In one embodiment, the extraction parameter is the extraction flow rate; determining whether the powder cake is broken based on the percolation time of the powder cake, the extraction parameters of the extraction process, and the on / off state of the powder pressing switch includes:

[0013] If the powder pressing switch is in the off state, the product of the extraction flow rate and the flow rate influence coefficient is not less than the set flow rate, and the product of the percolation time and the soaking influence coefficient is not less than the set time, it is determined that the powder cake has broken.

[0014] In one embodiment, obtaining the volume of the broken powder cake inside the waste container includes:

[0015] In the case where the powder compact breaks during the pouring process after the current extraction process, the volume of the powder compact used in the current extraction process is obtained, and the product of the powder compact volume and the breakage coefficient is taken as the volume of the broken powder compact produced in the current extraction process.

[0016] The volume of the broken powder cake produced in the current extraction process is added to the volume of the existing broken powder cake in the waste residue box to obtain the volume of the broken powder cake in the waste residue box.

[0017] In one embodiment, obtaining the volume of the powder cake used in the current extraction process includes:

[0018] Obtain the actual pressing time and the inverse proportional function between pressing time and powder thickness;

[0019] The thickness of the powder compact is obtained based on the actual pressing time and the inverse proportional function.

[0020] Multiply the thickness of the powder cake by the bottom area of ​​the powder cake container to obtain the volume of the powder cake used in the current extraction process.

[0021] In one embodiment, determining whether the waste container is full based on the volume of the broken powder compact, the volume of the intact powder compact, and the volume of the waste container includes:

[0022] The volume of the broken powder compact, the volume of the intact powder compact, and the volume of the allowable error are added together to obtain the volume of the poured powder compact.

[0023] If the volume of the poured powder is not less than the volume of the waste residue box, it is determined that the waste residue box is full.

[0024] Secondly, this application also provides a coffee machine waste container identification device, comprising:

[0025] The pouring module is used to pour the powder into the waste container after extraction;

[0026] The fragmentation volume acquisition module is used to acquire the volume of the fragmented powder cake in the waste residue box when the powder cake breaks during the pouring process.

[0027] The complete volume acquisition module is used to acquire the complete volume of the powder cake in the waste box if the powder cake does not break during the pouring process.

[0028] The judgment module is used to determine whether the waste container is full based on the volume of the broken powder compact, the volume of the intact powder compact, and the volume of the waste container.

[0029] Thirdly, this application also provides a coffee machine, including a memory, a processor, and a waste container, wherein the memory stores a computer program, and the processor executes the computer program to implement the steps of any of the above methods.

[0030] Fourthly, this application also provides a computer-readable storage medium. The computer-readable storage medium stores a computer program thereon, which, when executed by a processor, implements the steps of any of the methods described above.

[0031] Fifthly, this application also provides a computer program product. The computer program product includes a computer program that, when executed by a processor, implements the steps of any of the methods described above.

[0032] The aforementioned coffee machine waste container identification method and device, coffee machine, and storage medium, after extraction, pour the coffee puck into the waste container and obtain the volumes of broken and intact coffee pucks within the container. Based on these volumes and the container's volume, it determines whether the waste container is full. Compared to traditional technologies that suffer from low space utilization within the waste container, this application can obtain the volumes of broken and intact coffee pucks based on whether the puck is broken during the pouring process, and determine whether the container is full based on its volume. This ensures greater utilization of the waste container's space and improves its space utilization rate. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] This embodiment provides a method for identifying the contents of a coffee machine's waste container. This embodiment uses the application of this method to a coffee machine as an example for illustration. It can be understood that this method can also be applied to a system including a coffee machine and a server, and can be implemented through the interaction between the coffee machine and the server.

[0042] To aid understanding, a simplified explanation of some steps in making coffee using a coffee machine is provided here, but this does not constitute a limitation on the coffee-making process. First, the coffee beans need to be ground. Then, the beans are tamped initially in a pouch container, moistened, and tamped again. Next comes the extraction, after which the pouch is poured into the grounds container after each extraction.

[0043] Figure 1 This is a flowchart illustrating the coffee machine waste container identification method provided in this application embodiment. The method is applied to a coffee machine. In one embodiment, such as... Figure 1 As shown, it includes the following steps:

[0044] S101, after extraction, pour the powder into the waste container.

[0045] Extraction refers to the process of extracting water-soluble substances from coffee pucks using water. Coffee pucks are formed by pressing coffee grounds. A waste container is used to hold the extracted coffee pucks.

[0046] In some embodiments, there are multiple ways to pour the powder compact into the waste container. One way is to pour the powder compact into the waste container by flipping the powder compact container. Another way is to use a scraping device to help pour the powder compact into the waste container. The specific method is not limited.

[0047] S102, if the powder compact breaks during the pouring process, obtain the volume of the broken powder compact in the waste container.

[0048] The volume of the broken powder compact is the sum of the volumes of all the broken powder compacts in the waste container.

[0049] S103, obtain the complete volume of the powder compact in the waste container without it breaking during the pouring process.

[0050] The volume of a complete pressed powder compact is the sum of the volumes of all intact pressed powder compacts within the waste container. It should be understood that "complete" here refers to the concept relative to "broken," and does not mean the compact is perfectly intact.

[0051] S104, based on the volume of the broken powder compact, the volume of the intact powder compact, and the volume of the waste container, determine whether the waste container is full.

[0052] Among them, the volume of the waste residue box is the largest volume that can be contained within the waste residue box.

[0053] The coffee machine waste container identification method provided in this embodiment involves pouring the coffee puck into the waste container after extraction and obtaining the volumes of broken and intact coffee pucks. Based on these volumes and the waste container's volume, it is determined whether the waste container is full. Compared to traditional technologies that suffer from low space utilization in the waste container, this embodiment can obtain the volumes of broken and intact coffee pucks based on whether the puck is broken during the pouring process, and determine whether the waste container is full based on its volume. This ensures greater utilization of the waste container's space and improves its overall space efficiency.

[0054] In one embodiment, the process for determining whether the powder compact breaks during the pouring process includes:

[0055] During the pouring process, the powder cake is judged to be broken based on the filtration time, extraction parameters of the extraction process, and the opening and closing status of the powder pressing switch.

[0056] The percolation time is the duration from the initial addition of water to the powder cake until extraction is complete. Extraction parameters are the relevant parameters during the extraction process. These parameters include at least one of the extraction flow rate or extraction water pressure. The on / off status of the tamping switch is used to determine whether tamping is currently in progress.

[0057] In this embodiment, the filtration time, extraction parameters, and opening / closing status are used to determine whether the powder compact is broken. By considering multiple factors, the accuracy of the determination of whether the powder compact is broken can be guaranteed, providing a basis for obtaining the volume of broken powder compacts and the volume of intact powder compacts.

[0058] In one embodiment, the extraction parameter is the extraction flow rate; based on the percolation time of the powder cake, the extraction parameters of the extraction process, and the on / off state of the powder tamping switch, determining whether the powder cake is broken includes:

[0059] If the powder press switch is closed, the product of the extraction flow rate and the flow rate influence coefficient is not less than the set flow rate, and the product of the percolation time and the soaking influence coefficient is not less than the set time, the powder cake is judged to be broken.

[0060] The extraction flow rate refers to the water flow rate during the extraction process. When the water flow rate is constant, it is used as the extraction flow rate. When the water flow rate is variable, the water flow rate corresponding to the longest extraction time is used as the extraction flow rate, or the average water flow rate during the extraction process is taken as the extraction flow rate; the specific value is not limited. The flow rate influence coefficient and the soaking influence coefficient can be set manually. The flow rate can be set based on experimental results, and can be set to 10 ml / s; the specific value is not limited. The soaking time can be set based on experimental results, and can be set to 6 seconds; the specific value is not limited.

[0061] In this embodiment, the influence of extraction flow rate and filtration time on the determination of whether the powder cake is broken can be adjusted by using the flow rate influence coefficient and immersion influence coefficient. The flow rate and immersion time are set according to the experimental results, which can improve the accuracy of the determination.

[0062] In another embodiment, the extraction parameter is the extraction water pressure; based on the percolation time of the powder cake, the extraction parameters of the extraction process, and the opening and closing state of the powder pressing switch, the determination of whether the powder cake is broken includes:

[0063] If the powder pressing switch is off, the product of the extraction water pressure and the water pressure influence coefficient is not greater than the set water pressure, and the product of the percolation time and the soaking influence coefficient is not less than the set time, the powder cake is judged to be broken.

[0064] The extraction water pressure refers to the pressure exerted by water on the walls of the water channel during the extraction process. The water pressure influence coefficient and the immersion influence coefficient can be set manually. The water pressure and immersion time can be set based on experimental results.

[0065] In this embodiment, considering the extraction water pressure, the opening and closing status of the powder pressing switch, and the percolation time, and taking into account multiple factors, the accuracy of the judgment on whether the powder cake is broken can be guaranteed, providing a basis for subsequently obtaining the volume of broken powder cake and the volume of intact powder cake.

[0066] In another embodiment, the extraction parameters include extraction water pressure and extraction flow rate; based on the percolation time of the powder cake, the extraction parameters of the extraction process, and the on / off state of the powder pressing switch, determining whether the powder cake is broken includes:

[0067] If the powder press switch is off, the product of the extraction water pressure and the water pressure influence coefficient is not greater than the set water pressure, the product of the extraction flow rate and the flow rate influence coefficient is not less than the set flow rate, and the product of the percolation time and the soaking influence coefficient is not less than the set time, the powder cake is judged to be broken.

[0068] The extraction water pressure and extraction flow rate are inversely proportional. The influence coefficients for water pressure and flow rate are set differently.

[0069] In this embodiment, both extraction water pressure and extraction flow rate are considered. Although there is an inverse relationship between extraction water pressure and extraction flow rate, they may have different effects on the degree of impact on the determination of whether the powder compact is broken, which can further ensure the accuracy of the determination of whether the powder compact is broken.

[0070] In one embodiment, a flowchart illustrating the process of obtaining the volume of broken powder compacts within the waste container is shown below. Figure 2 As shown, it includes the following:

[0071] S201, for the current extraction process, if the powder compact breaks during the pouring process after the current extraction process, obtain the volume of the powder compact used in the current extraction process, and use the product between the powder compact volume and the breakage coefficient as the volume of the broken powder compact produced in the current extraction process.

[0072] The fragmentation coefficient is a factor reflecting the relationship between the volume of a broken powder compact and its intact volume. Specifically, the value of the fragmentation coefficient can be set based on experimental results. It should be understood that broken powder compacts are more likely to remain in the container, and the volume of broken powder compacts in the waste container will also change relative to the intact compact.

[0073] S202, add the volume of the broken powder cake produced in the current extraction process to the volume of the existing broken powder cake in the waste residue box to obtain the volume of the broken powder cake in the waste residue box.

[0074] In this embodiment, the volume of broken powder is calculated by multiplying the volume of the powder compact by the breakage coefficient, so that the obtained volume of broken powder is more realistic and accurate, which can avoid affecting the subsequent judgment result of whether the waste box is full.

[0075] In one embodiment, a flowchart illustrating the process of obtaining the powder volume used in the current extraction process is shown below, such as... Figure 3 As shown, it includes the following:

[0076] S301, obtain the actual pressing time and the inverse proportional function between pressing time and powder thickness.

[0077] It should be understood that the moving distance of the pressing device can be obtained from the pressing time, and the thickness of the powder cake can be obtained from the moving distance of the pressing device.

[0078] S302, based on the actual pressing time and an inverse proportional function, obtains the thickness of the pressed powder.

[0079] S303, multiply the thickness of the pressed powder by the bottom area of ​​the pressed powder container to obtain the volume of the pressed powder used in the current extraction process.

[0080] The puck container is a container used to hold coffee powder. The shape of the puck container can be cylindrical, and there are no specific restrictions.

[0081] In this embodiment, since the volume of the powder compact cannot be obtained directly, it is calculated by the actual pressing time and the bottom area of ​​the powder compact container, which is convenient, simple, and highly accurate.

[0082] In one embodiment, a flowchart illustrating the process of determining whether a waste container is full based on the volume of a broken powder compact, the volume of a intact powder compact, and the volume of the waste container is shown below. Figure 4 As shown, it includes the following:

[0083] S401, add the volume of the broken powder compact, the volume of the intact powder compact, and the volume of the allowable error to obtain the volume of the poured powder compact.

[0084] The reserved error volume is used to avoid errors when calculating the volume of the pressed powder. The reserved error volume can be set manually.

[0085] S402, if the volume of the poured powder is not less than the volume of the waste container, it is determined that the waste container is full.

[0086] In this embodiment, the volume of the poured powder cake is taken into account to allow for a margin of error, which can avoid errors in the calculation process. When the volume of the poured powder cake is not less than the volume of the waste residue box, it is determined that the waste residue box is full. No additional sensor is required, which reduces costs and ensures that the space inside the waste residue box is utilized to a greater extent, thus improving the space utilization rate inside the waste residue box. The determination of whether the waste residue box is full is also more accurate.

[0087] Here, we provide a detailed explanation of the method for identifying the contents of a coffee machine's waste container. Taking the coffee-making process using a coffee machine, which includes grinding, initial tamping, wetting, re-tamping, extraction, and finally pouring the coffee puck into the waste container, as an example, the implementation process of this coffee machine waste container identification method includes:

[0088] After extraction, check whether the powder compact breaks during pouring;

[0089] Specifically, if the powder pressing switch is closed, the product of the extraction flow rate and the flow rate influence coefficient is not less than the set flow rate, and the product of the percolation time and the soaking influence coefficient is not less than the set time, the powder cake is judged to have broken; otherwise, the powder cake is judged not to have broken.

[0090] If the powder compact breaks during the pouring process, obtain the volume of the broken powder compact in the waste container;

[0091] Specifically, for the current extraction process, if the powder cake breaks during the pouring process after the current extraction process, the actual pressing time and the inverse proportional function between the pressing time and the powder cake thickness are obtained. Based on the actual pressing time and the inverse proportional function, the powder cake thickness is obtained. The powder cake thickness is multiplied by the bottom area of ​​the powder cake container to obtain the powder cake volume used in the current extraction process. The product between the powder cake volume and the breakage coefficient is taken as the volume of broken powder cake produced in the current extraction process. The volume of broken powder cake produced in the current extraction process is added to the existing volume of broken powder cake in the waste container to obtain the volume of broken powder cake in the waste container.

[0092] The volume of the intact powder compact inside the waste container was obtained without the compact breaking during the pouring process.

[0093] Specifically, for the current extraction process, assuming no powder compact breaks during the subsequent pouring process, the actual pressing time and the inverse proportional function between pressing time and powder compact thickness are obtained. Based on the actual pressing time and the inverse proportional function, the powder compact thickness is obtained. The powder compact thickness is multiplied by the bottom area of ​​the powder compact container to obtain the powder compact volume used in the current extraction process. The powder compact volume used in the current extraction process is added to the volume of the existing intact powder compact in the waste container to obtain the volume of the intact powder compact in the waste container.

[0094] Add the volume of the broken powder compact, the volume of the intact powder compact, and the volume of the allowable error to get the volume of the powder compact poured out. If the volume of the powder compact poured out is not less than the volume of the waste container, it is determined that the waste container is full.

[0095] If the waste container is found to be full, the user will be prompted to empty the waste container and stop extraction. Extraction will only resume after the waste container presence sensor signal changes.

[0096] The coffee machine waste container identification method provided in this embodiment determines whether the coffee puck is broken by measuring the filtration time of the coffee puck, the extraction parameters of the extraction process, and the on / off state of the tamper switch. It then obtains the volumes of the broken and intact coffee pucks in the waste container, and also considers a reserved error volume. The sum of the volumes of the broken, intact, and reserved error volumes is compared with the volume of the waste container to determine whether the waste container is full. This method maximizes the utilization of the space in the waste container, reduces the frequency of emptying the waste container, and improves the user experience.

[0097] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.
