[0002] Generally speaking, coffee can be divided into espresso and extraction coffee according to the production method. Espresso aims to extract as much flavor of coffee beans as possible into a small amount of water, while extraction coffee aims to bring out flavors other than coffee flavor. Compared with espresso, the biggest advantage of extraction coffee is that it can extract the complex flavor of coffee and distinguish the characteristics of different coffee beans.

[0003] The taste of the extracted coffee made by the boutique coffee machines on the market has always been the focus of consumers' attention. In addition to the expected bitterness and sourness of coffee, a good cup of extracted coffee can also taste sweetness, floral aroma, fruity flavor, etc. However, since the flavor of coffee is related to many factors, such as coffee extraction time, coffee concentration, coffee brewing water temperature, etc., during the coffee brewing process, the bitterness and astringency of the coffee may be released due to over-extraction, making the bitterness and astringency of the brewed coffee prominent, thus affecting the taste of the coffee. Summary of the invention

[0004] The embodiments of the present application provide a coffee brewing method, device, drip coffee machine and readable storage medium, which can solve the technical problem that excessive extraction may occur during coffee brewing, resulting in prominent bitterness and astringency in the brewed coffee, thereby affecting the taste of the coffee.

[0009] In a second aspect, an embodiment of the present application provides a coffee brewing device, comprising:

[0010] An acquisition unit, used for acquiring coffee brewing parameters;

[0011] A judging unit, configured to judge whether the coffee brewing has a possibility of over-extraction based on the coffee brewing parameters;

[0012] An execution unit is used for, if there is a possibility of over-extraction in the coffee brewing, after injecting a target amount of water corresponding to the coffee brewing parameter into a coffee cup of the drip coffee machine, and then brewing the coffee according to the coffee brewing parameter.

[0013] In a third aspect, an embodiment of the present application provides a drip coffee machine, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of the method of the first aspect when executing the computer program.

[0014] In a fourth aspect, an embodiment of the present application provides a computer-readable storage medium, which stores a computer program. When the computer program is executed by a processor, the steps of the method of the first aspect are implemented.

[0015] In an embodiment of the present application, coffee brewing parameters are obtained, and based on the coffee brewing parameters, it is determined whether the coffee brewing has the possibility of over-extraction. If the coffee brewing has the possibility of over-extraction, after a target amount of water corresponding to the coffee brewing parameters is injected into the coffee cup of the drip coffee machine, the coffee is brewed according to the coffee brewing parameters, thereby achieving a preliminary judgment based on the coffee brewing parameters before coffee brewing, and when it is determined that the coffee brewing has the possibility of over-extraction, a certain amount of water is pre-injected into the coffee cup of the drip coffee machine to dilute the bitterness and astringency in the coffee caused by over-extraction in the subsequent coffee brewing process, thereby effectively avoiding the bitterness and astringency in the brewed coffee due to possible over-extraction during coffee brewing, thereby improving the taste of the coffee.

[0028] Nowadays, coffee is favored by more and more people because of its unique aroma and certain refreshing effect.

[0029] Generally speaking, coffee can be divided into espresso and extraction coffee according to the production method. Espresso aims to extract as much flavor of coffee beans as possible into a small amount of water, while extraction coffee aims to bring out flavors other than coffee flavor. Compared with espresso, the biggest advantage of extraction coffee is that it can extract the complex flavor of coffee and distinguish the characteristics of different coffee beans.

[0030] Coffee beans contain caffeine, acid, lipids, sugar, carbohydrates and other substances. During the coffee extraction process, these substances in the coffee beans are extracted, which has a direct impact on the flavor and aroma of the coffee. A good cup of extracted coffee usually tastes sweet, floral, fruity, etc. in addition to the expected bitterness and sourness of coffee. However, during the coffee extraction process, the substances in the coffee beans are not all extracted at the same rate. Usually, the fruity and sour flavors are extracted first, followed by the sweetness, and finally the bitterness. The extraction rate of coffee substances is related to many factors, such as the extraction time of coffee, the concentration of coffee, the brewing water temperature of coffee, etc. Therefore, during the coffee brewing process, it is very likely that the bitterness and astringency in the coffee will be released more due to over-extraction, making the bitterness and astringency of the brewed coffee prominent, which in turn affects the taste of the coffee.

[0031] Typically, the brewing steps of a drip coffee machine for making extracted coffee are: pouring powder → pouring water → extraction. First, add coffee powder to the filter cup of the drip coffee machine, and then inject hot water at a certain temperature into the filter cup through the water outlet to extract the coffee. During this process, the extracted coffee gradually flows from the filter cup to the coffee cup placed under the filter cup, thereby completing the coffee brewing.

[0032] In the related art, a water outlet is added to the drip coffee machine so that after the coffee is extracted, hot water is injected into the coffee cup from the water outlet to neutralize the taste of the coffee. However, this method complicates the design of the drip coffee machine itself and increases the cost.

[0033] Based on the above problems, the embodiments of the present application provide a coffee brewing method, device and computer-readable storage medium, which can avoid the bitterness and astringency of the brewed coffee due to possible over-extraction during coffee brewing, thereby improving the taste of the coffee.

[0034] In order to illustrate the above technical solution of the present application, the following is a description with reference to the accompanying drawings and through specific embodiments.

[0035] For example, Figure 1 The following is a schematic diagram of a coffee brewing method provided in an embodiment of the present application, which can be applied to a drip coffee machine. For example, Figure 2 , a schematic diagram of the structure of a drip coffee machine 2 is shown, and the drip coffee machine 2 comprises a heating tube and a water pump 21, a water outlet 22, a filter 23 and a coffee cup 24. The heating tube and the water pump 21 are used to heat water to a certain temperature and then transfer water to the water outlet 22, and the water is added from the water outlet 22 to the filter cup 23 under the water outlet, and can flow to the coffee cup 24 under the filter cup. The drip coffee machine can implement the above-mentioned coffee brewing method, and the coffee brewing method specifically comprises the following steps 101 to 103.

[0036] Step 101: Obtain coffee brewing parameters;

[0037] Among them, the above-mentioned coffee brewing parameters can be one or more of the amount of coffee beans, coffee coarseness, coffee brewing powder-water ratio, coffee brewing capacity, coffee brewing steaming water volume, coffee brewing extraction water volume, coffee extraction time, coffee brewing temperature, coffee brewing section number, etc., which are related to the specific brewing procedure of the drip coffee machine, and this application does not impose any restrictions on this.

[0038] Furthermore, the types of the above-mentioned coffee brewing parameters may include coffee brewing parameters input by a user, coffee brewing parameters preset by a drip coffee machine, and coffee brewing parameters calculated based on partial coffee parameters input by a user and coffee brewing parameters preset by the drip coffee machine. For example, a drip coffee machine can calculate appropriate coffee brewing parameters such as a suitable coffee brewing temperature and coffee extraction time based on coffee brewing parameters input by a user such as the amount of coffee beans, coffee coarseness, coffee brewing powder-water ratio, and coffee brewing capacity.

[0039] Step 102: Based on the coffee brewing parameters, determine whether the coffee brewing is likely to be over-extracted;

[0040] Normally, during the coffee extraction process, the fruity and sour flavors are extracted first, followed by the sweetness, and finally the bitterness. That is, the release of bitterness in the coffee beans is related to the extraction time. Therefore, a time threshold can be set to determine whether the coffee brewing is likely to be over-extracted.

[0041] For example, in some embodiments of the present application, the above-mentioned coffee brewing parameters include coffee extraction time. In the process of judging whether there is a possibility of over-extraction of coffee brewing based on the above-mentioned coffee brewing parameters, it can be determined by judging whether the coffee extraction time is greater than the preset extraction time. If the coffee extraction time is greater than the preset extraction time, it is determined that there is a possibility of over-extraction of coffee brewing.

[0042] Specifically, the coffee extraction time can be determined based on the barista's brewing experience, or can be set based on the user's taste preference for the bitterness and astringency of the coffee, and this application does not impose any restrictions on this.

[0043] Optional, in practical applications, such as Figure 2 As shown, coffee powder is added to the filter cup 23 of the drip coffee machine 2 at one time, and as the coffee brewing capacity increases, the extraction time of coffee will also increase accordingly, and more bitterness and astringency of coffee may be released. Therefore, in some embodiments of the present application, it is also possible to set a coffee brewing capacity threshold to determine whether there is a possibility of over-extraction in the coffee brewing process, that is, the above-mentioned coffee brewing parameters include the coffee brewing capacity. In the above-mentioned process of judging whether there is a possibility of over-extraction in coffee brewing based on the coffee brewing parameters, it can be judged whether the coffee brewing capacity is greater than the preset coffee brewing capacity. If the coffee brewing capacity is greater than the preset coffee brewing capacity, it is determined that the coffee brewing is over-extracted.

[0044] Exemplarily, the above-mentioned coffee brewing capacity and preset coffee brewing capacity can be the coffee brewing capacity value (for example, the coffee brewing capacity is 450g, and the preset coffee brewing capacity is 300g. At this time, the coffee brewing capacity is greater than the preset coffee brewing capacity), and can also be the number of cups corresponding to the setting of the drip coffee machine (for example, the setting in a certain drip coffee machine is that the capacity value of one cup is 150g, the coffee brewing capacity is 3 cups, and the preset coffee brewing capacity is 2 cups. At this time, the coffee brewing capacity is greater than the preset coffee brewing capacity), etc., and the present application does not impose any restrictions on this.

[0045] It should be noted that the above-mentioned coffee brewing capacity can also be obtained by calculating the coffee brewing powder-water ratio and the amount of beans, and the present application does not impose any limitation on this.

[0046] It should be noted that the above-mentioned preset coffee brewing capacity can be determined based on the barista's brewing experience, or can be determined based on the user's taste preference for the bitterness and astringency of coffee, and the present application does not impose any restrictions on this.

[0047] Step 103: If there is a possibility of over-extraction in the coffee brewing, after injecting a target amount of water corresponding to the coffee brewing parameter into the coffee cup of the drip coffee machine, the coffee is brewed according to the coffee brewing parameter.

[0048] Specifically, Figure 2 The drip coffee machine 2 shown, after determining that there is a possibility of over-extraction in coffee brewing, can heat water to a certain temperature through the heating tube and the water pump 21 and adjust the water to the water outlet 22, and then add the target water volume at the certain temperature into the filter cup 23 of the drip coffee machine, and then flow into the coffee cup 24 of the drip coffee machine. At this time, the coffee cup contains the target water volume at the certain temperature, which can be used to neutralize the coffee liquid extracted in the subsequent over-extraction of coffee brewing.

[0049] The amount of water pre-injected (target water amount) is related to coffee brewing parameters, for example, it may be related to coffee brewing capacity, coffee brewing steaming water amount and coffee brewing extraction water amount.

[0050] Among them, the above-mentioned brewing of coffee according to the coffee brewing parameters refers to performing conventional coffee brewing operations according to the coffee brewing parameters, for example, including powder injection, extraction, etc., so as to neutralize the extracted coffee concentrate with the target amount of water added in advance to obtain brewed coffee.

[0051] It is understandable that in some embodiments, if there is no possibility of over-extraction in coffee brewing, coffee can be brewed according to the coffee brewing parameters without performing the above-mentioned pre-injection operation of injecting a target amount of water corresponding to the coffee brewing parameters into the coffee cup of the drip coffee machine.

[0052] In an embodiment of the present application, coffee brewing parameters are obtained, and based on the coffee brewing parameters, it is determined whether there is a possibility of over-extraction in coffee brewing. If there is a possibility of over-extraction in coffee brewing, after a target amount of water corresponding to the coffee brewing parameters is injected into the coffee cup of the drip coffee machine, coffee is brewed according to the coffee brewing parameters. This achieves a preliminary judgment based on the coffee brewing parameters before coffee brewing, and when it is determined that there is a possibility of over-extraction in coffee brewing, a certain amount of water is pre-injected into the coffee cup of the drip coffee machine to dilute the bitterness and astringency in the coffee caused by over-extraction in the subsequent coffee brewing process. There is no need to add an additional water outlet to neutralize the coffee taste. This effectively avoids the problem of bitterness and astringency in the brewed coffee due to possible over-extraction during coffee brewing without increasing the complexity of the drip coffee machine, thereby improving the taste of the coffee.

[0053] In some embodiments of the present application, the above-mentioned coffee brewing parameters include: the amount of water for steaming coffee, the amount of water for extracting coffee and the coffee brewing capacity. If there is a possibility of over-extraction in the coffee brewing, the amount of water injected into the coffee cup of the drip coffee machine (target water amount) can be determined based on the coffee brewing capacity, the amount of water for steaming coffee and the amount of water for extracting coffee. That is, the above-mentioned coffee brewing method also includes: subtracting the amount of water for steaming coffee and the amount of water for extracting coffee from the coffee brewing capacity to obtain the target water amount.

[0054] Specifically, in order to meet the user's coffee brewing capacity requirements, the total amount of water added during the coffee brewing process (for example, including pre-injection water, steaming water, and extraction water) can be kept equal to the coffee brewing capacity.

[0055] For example, if the amount of coffee beans in the coffee brewing parameters is 30g and the powder-water ratio is 1:15, then the coffee brewing capacity is determined to be 30×15=450g. If the amount of water for coffee brewing steaming in the coffee brewing parameters is 50g and the amount of water for coffee brewing extraction is 300g, then the amount of water pre-injected (target water amount) can be determined to be 450-300-50=100g.

[0056] It should be noted that the above-mentioned coffee brewing steaming water volume and coffee brewing extraction water volume can be determined according to other coffee brewing parameters. For example, the most suitable coffee brewing steaming water volume and coffee brewing extraction water volume can be determined in combination with the actual coffee brewing experience of the barista, or the brewing experience of the brand of coffee beans. The users can also set it according to their own drinking habits and usage experience, and this application does not impose any restrictions on this.

[0057] In actual applications, the brewing temperature of coffee is generally 85-95 degrees Celsius. In order to avoid lowering the temperature of the brewed coffee and affecting the taste of the coffee due to water injection, optionally, in some embodiments of the present application, the above-mentioned coffee brewing parameters include coffee brewing temperature, and the temperature of the above-mentioned target water volume injected corresponding to the coffee brewing parameters is higher than the coffee brewing temperature, which can achieve the purpose of warming the filter cup of the drip coffee machine and the coffee cup of the drip coffee machine while avoiding affecting the taste of the coffee obtained by subsequent extraction.

[0058] In specific applications, drip coffee machines are divided into those with and without a bean grinding function. For a drip coffee machine with a bean grinding function, it is usually necessary to grind the beans to brew coffee. For example, Figure 3 As shown, a second implementation flow chart of a coffee brewing method provided by the present application specifically includes the following steps 301 to 303.

[0059] Step 301: Obtain coffee brewing parameters;

[0060] Among them, the above coffee brewing parameters include coffee coarseness;

[0061] Step 31: Determine whether coffee beans are placed in the bean bin of the drip coffee machine;

[0062] Step 32: If coffee beans are placed in the bean bin of the drip coffee machine, grind the coffee beans according to the coarseness of the coffee to obtain coffee powder corresponding to the coarseness of the coffee;

[0063] Step 302: Based on the coffee brewing parameters, determine whether the coffee brewing is likely to be over-extracted;

[0064] Among them, step 302 is the same as the above step 102 and will not be repeated here.

[0065] Step 303: If there is a possibility of over-extraction in the coffee brewing, after injecting a target amount of water corresponding to the coffee brewing parameters into the coffee cup of the drip coffee machine, coffee powder corresponding to the coarseness of the coffee is added into the filter cup of the drip coffee machine to extract the coffee.

[0066] Specifically, since it is necessary to inject a target amount of water into the coffee cup of the drip coffee machine in advance when there is a possibility of over-extraction during coffee brewing, and the injected water usually flows into the coffee cup after passing through the filter cup, the above-mentioned injection of the target amount of water into the coffee cup should be performed before adding the coffee powder corresponding to the coarseness of the coffee into the filter cup of the drip coffee machine.

[0067] It should be noted that, for the above steps 31 to 32 of determining whether there are beans in the bean bin and the grinding operation of the beans, the operation can be performed after injecting a target amount of water corresponding to the coffee brewing parameters into the coffee cup of the drip coffee machine in the above step 103, so as to inject the coffee powder corresponding to the coarseness of the coffee into the filter cup of the drip coffee machine for coffee brewing. It can also be performed before injecting a target amount of water corresponding to the coffee brewing parameters into the coffee cup of the drip coffee machine in the above step 103, and in the case of the possibility of over-extraction of coffee brewing, the ground coffee powder corresponding to the coarseness of the coffee is injected into the filter cup of the drip coffee machine for coffee brewing after injecting the target amount of water in advance. The present application does not impose any restrictions on this.

[0068] For example, Figure 4 A specific coffee brewing scenario is shown in the figure. In a drip coffee machine 20, the preset capacity of one cup of coffee is 150g. After obtaining the coffee brewing parameters: [Number of brewing cups, 3 cups], [Powder-water ratio, 1:15], [Amount of bean powder, 30g], [Coarseness, medium], [Brewing temperature, 90°C], [Amount of steaming water, 50g], and [Amount of extraction water, 300g], and based on the fact that [Number of cups, 3 cups] is greater than [Preset number of brewing cups, 2 cups], it is determined that the coffee brewing may be over-extracted.

[0069] Pre-water injection 40: After heating the water in the water tank in the drip coffee machine to a temperature higher than the coffee brewing temperature (for example, 95 degrees), the amount of water to be injected (target water amount) is calculated according to the coffee brewing parameters as 450g-50g-300g=100g, and then the water pump in the drip coffee machine adjusts 95 degrees and 100g of water to the water outlet above the filter cup, injects it into the filter cup, and flows into the coffee cup below the filter cup.

[0070] Grinding beans 41: After injecting the target amount of water into the coffee cup, determine whether there are coffee beans in the bean bin of the drip coffee machine. If there are coffee beans in the bean bin, grind 30g of coffee beans according to [coarseness, medium] to obtain coffee powder with medium coarseness;

[0071] Powder injection 42: Add coffee powder with medium coarseness into the filter cup of the drip coffee machine;

[0072] Extraction 43: 50 g of water heated to a certain temperature (for example, 93° C.) by a heating tube is added to the filter cup of the drip coffee machine through the water outlet above the filter cup through a water pump and steamed for a period of time. Then, 100 g of water at a certain temperature (for example, 90 degrees) is added in three portions to extract coffee. The extracted coffee concentrate flows from the filter cup to a coffee cup filled with a pre-injected target amount of water. The pre-injected water is neutralized with the coffee concentrate to obtain brewed coffee.

[0073] In some embodiments of the present application, in the process of determining whether coffee beans are placed in the bean bin of the drip coffee machine in the above step 31, if coffee beans are not placed in the bean bin of the drip coffee machine, a bean injection prompt message can be output to prompt the user to inject beans, and then the coffee beans can be ground according to the coarseness of the coffee to obtain coffee powder corresponding to the coarseness of the coffee and grind the coffee beans. If there is a possibility of over-extraction in coffee brewing, after pre-injecting a target amount of water, the coffee powder of the coffee coarseness obtained after grinding is injected into the filter cup for subsequent coffee extraction.

[0074] For example, after the user fills beans into the bean bin of the drip coffee machine according to the reminder, the drip coffee machine can execute the above steps 31, 32, 302 and 303 to complete the brewing of coffee.

[0075] Optionally, in some embodiments, during the process of determining whether coffee beans are placed in the bean bin of the drip coffee machine in the above step 31, if no coffee beans are placed in the bean bin of the drip coffee machine, it is also possible to output a reminder message for filling powder after pre-injecting a target amount of water when there is a possibility of over-extraction of coffee, so as to prompt the user to directly fill the powder into the filter cup for subsequent coffee extraction.

[0076] Optionally, if the drip coffee machine does not have a grinding function, in some embodiments, the above-mentioned coffee brewing method may further include determining whether coffee powder is placed in the drip coffee machine; if coffee powder is placed in the drip coffee machine, then when it is determined that the coffee may be over-extracted, after injecting a target amount of water corresponding to the coffee brewing parameters into the coffee cup of the drip coffee machine, injecting coffee powder into the filter cup of the drip coffee machine to extract the coffee.

[0077] Optionally, in some embodiments, if the drip coffee machine does not have a grinding function, if during the above process of determining whether coffee powder is placed in the drip coffee machine, if no coffee powder is placed in the drip coffee machine, then when it is determined that the coffee may be over-extracted, after injecting a target amount of water corresponding to the coffee brewing parameters into the coffee cup of the drip coffee machine, a powder injection prompt message may be output to prompt the user to inject coffee powder into the filter cup for subsequent coffee extraction.

[0078] It should also be noted that, for the sake of simplicity of description, the aforementioned method embodiments are all expressed as a series of action combinations, but those skilled in the art should know that the present application is not limited to the described order of actions, and in some embodiments of the present application, certain steps may be performed in other orders.
