Description

Technical Field

[0001] The present invention relates to the technical field of coffee brewing, and in particular to a coffee brewing method and a coffee machine. Background Art

[0002] As an important tool for making coffee, the performance and efficiency of coffee machines are crucial to the coffee industry and coffee lovers. However, the current automation technology of drip coffee machines faces a series of challenges, one of which is that the degree of automation is not high enough and the product efficiency is low. In addition, in the operation of drip coffee machines, the cleaning of coffee grounds is an important link. Failure to clean the coffee grounds in time will cause the inside of the coffee machine to be damp. The humid environment provides conditions for the growth of bacteria, which in turn affects the hygiene quality and taste of the coffee. In summary, the low degree of automation of drip coffee machines, low product efficiency, and internal moisture and bacterial growth caused by cleaning problems have become bottlenecks in the current development of coffee machine technology. Summary of the invention

[0003] Based on this, it is necessary to provide a coffee brewing method and a coffee machine to address the problems of low efficiency of traditional drip coffee machines and moisture inside the coffee machine caused by untimely cleaning of coffee grounds.

[0004] A coffee brewing method comprises the following steps:

[0005] S1, start the coffee machine;

[0006] S2, the bean grinding component automatically grinds the coffee beans into coffee powder and delivers the coffee powder to the powder hopper;

[0007] S3, after the grinding is completed, the powder hopper rotates from the initial position to the brewing position, and the rotation time is recorded as T. The brewing component injects hot water into the powder hopper to complete the brewing;

[0008] S4, after brewing is completed, the powder hopper rotates, and the rotation time is set to X, so that the powder hopper moves to the position between the grinding component and the brewing component;

[0009] S5. After cleaning the coffee grounds in the powder hopper, the powder hopper rotates and returns to its initial position.

[0010] The first aspect of the present application discloses a coffee brewing method, which fully utilizes the advantages of automation technology, and realizes automated operation from starting the coffee machine to grinding beans, conveying coffee powder, brewing and other steps, which not only greatly improves the efficiency of coffee making, but also reduces the tediousness and errors of manual operation, making coffee making more accurate and convenient. The functions of automatic grinding and brewing can ensure that the coffee beans are ground and brewed in the best state, ensuring the taste and quality of the coffee. At the same time, the precise control of the hot water injected into the brewing component makes the extraction of coffee more uniform, further improving the quality of coffee. The rotating and moving design of the powder hopper is convenient for users to clean the coffee grounds in time, and requires users to manually confirm that the grounds have been poured out before resetting. If the coffee grounds are not cleaned before resetting, it will cause the inside of the coffee machine to get damp and produce bacteria, affecting the quality and hygiene of the coffee. In addition, when the powder hopper is in the initial position or the brewing position, a sensor can be installed to detect whether the powder hopper has moved into place, so that the coffee machine starts to automatically grind beans or brew automatically. The coffee machine can automatically record the time T taken by the powder hopper to rotate from the initial position to the brewing position, and then calculate and set the time X for the powder hopper to rotate, so that the powder hopper moves to the position between the grinding component and the brewing component, which is convenient for users to manually clean the coffee grounds. Through precise time setting, the entire brewing process is more accurate and faster, and the overall automation of the coffee machine is improved.

[0011] In any of the above technical solutions, step S1 includes the following specific steps:

[0012] S11, the coffee machine receives a start instruction;

[0013] S12, the coffee machine performs a self-check to ensure that the powder hopper is in the initial position;

[0014] S13, start the instant heater for preheating.

[0015] When the coffee machine receives a start command, it will quickly enter the working state, so that when the user needs coffee, there is no need to wait for the coffee machine to respond, which improves the efficiency of use. The coffee machine performs a self-check and confirms that the powder hopper is in the initial position, ensuring that the preparations before coffee brewing are completed accurately, improving the safety and stability of the coffee machine. In addition, the coffee machine's self-check steps help to promptly discover and resolve potential equipment problems, thereby reducing the need for maintenance due to improper operation or equipment failure and extending the service life of the coffee machine. By starting the instant heater for preheating, the brewing process of coffee powder can be started immediately when the user chooses to brew, without waiting for the heater to heat up, saving time and improving brewing efficiency.

[0016] In any of the above technical solutions, step S2 includes the following specific steps:

[0017] S21, the bean grinding component receives a bean grinding instruction;

[0018] S22, the bean grinding component automatically adjusts the bean grinding parameters according to the preset coffee powder coarseness;

[0019] S23. After the bean grinding is completed, the bean grinding assembly automatically stops and delivers coffee powder to the powder hopper.

[0020] By automating the bean grinding process, from receiving the bean grinding instruction to completing the grinding and delivering the coffee powder, the coffee preparation process is greatly simplified and time is saved. Adjusting the bean grinding parameters according to the preset coffee powder coarseness can ensure that the coffee beans are ground into the most suitable particle size for brewing, thereby improving the aroma, taste and mouthfeel of the coffee. In addition, precise control of the bean grinding process and the coarseness of the coffee powder can greatly improve the quality of the brewed coffee. The bean grinding component automatically stops after the bean grinding is completed and delivers the coffee powder to the powder hopper, avoiding the safety hazards that may be caused by manual operation, and avoiding the manual delivery of coffee powder that causes the coffee powder to fly and is difficult to clean, making the entire coffee brewing process more convenient and clean. The automated bean grinding and powder delivery process makes the coffee machine more compact in design and layout, saves space, and reduces unnecessary manual operations, thereby saving human resources.

[0021] In any of the above technical solutions, in step S2, the time for the bean grinding assembly to deliver coffee powder to the powder hopper is a fixed value preset by the user.

[0022] By presetting fixed values, the time for the grinder to deliver coffee powder to the powder hopper can be precisely controlled, thereby ensuring a consistent amount of coffee powder for each brew, which helps to ensure the taste and quality of the coffee. Users can preset the delivery time of coffee powder according to their tastes and needs, making brewing coffee easier and more convenient. Users can easily make delicious coffee without professional coffee brewing knowledge. By simply controlling the amount of coffee powder, the operation process of brewing coffee is greatly simplified, while reducing the difficulty of operating the coffee machine.

[0023] In any of the above technical solutions, step S3 includes the following specific steps:

[0024] S31, after receiving the rotation instruction, the powder hopper rotates to the preset brewing position to ensure that the powder hopper is aligned with the brewing component, and the system automatically records the rotation time T;

[0025] S32, after receiving the brewing instruction, the brewing component adjusts and supplies hot water according to the preset water temperature and water volume parameters;

[0026] S33, the brewing component injects hot water into the powder hopper for brewing;

[0027] S34. After the hot water injection is completed, the brewing component automatically stops.

[0028] When the powder hopper receives the rotation instruction and rotates to the brewing position, the system automatically records the rotation time T, ensuring the accurate positioning of the powder hopper and avoiding the difference in coffee taste or brewing failure caused by too long or too short rotation time. Sensors can be installed at corresponding positions on the powder hopper and the brewing component to ensure that the powder hopper is aligned with the brewing component when it rotates to the preset brewing position, thereby ensuring the stability of the subsequent automatic brewing process, while avoiding the tedious operation of alignment and improving the automation of the brewing process. The brewing component can accurately adjust the supply of hot water according to the preset water temperature and water volume parameters, ensuring accurate water temperature control during the coffee brewing process, avoiding the difference in coffee taste caused by too high or too low water temperature. At the same time, precise control of the water volume ensures the stability of the coffee concentration, so that each brewed coffee can achieve the ideal taste.

[0029] In any of the above technical solutions, in step S3, the time for the brewing component to inject hot water into the powder hopper is a fixed value preset by the user.

[0030] By presetting a fixed brewing time, you can ensure that the contact time between hot water and coffee powder is consistent every time you brew coffee, which helps to accurately control the degree of extraction, flavor and mouthfeel of the coffee. Presetting a fixed brewing time can greatly improve the efficiency of the brewing process. Users do not need to manually adjust or monitor the brewing time every time. Just set the preset value and the brewing component can automatically complete the entire brewing process, saving time. The use of preset brewing time greatly simplifies the operation steps of coffee brewing. Users do not need to have professional coffee knowledge or experience. They only need to select the appropriate preset value according to their taste to easily brew delicious coffee. This design provides users with sufficient flexibility to meet different taste preferences and demand scenarios.

[0031] In any of the above technical solutions, the ratio of X to T is 1:3 to 2:3.

[0032] The coffee machine system automatically records the time T for the powder hopper to rotate from the initial position to the brewing position, and then automatically calculates the rotation time of the powder hopper as X according to the algorithm, and the ratio of X to T is between 1:3 and 2:3 (the ratio of X to T can be 1:3, 1:2, 2:3, etc.). When the rotation time of the powder hopper is X, the powder hopper will move to the position between the grinding component and the brewing component, so that the user can take out the powder hopper and clean the coffee grounds.

[0033] In any of the above technical solutions, step S4 includes the following specific steps:

[0034] S41, the powder hopper receives a rotation instruction;

[0035] S42, the powder hopper rotates, and the system automatically calculates and sets the rotation time to X;

[0036] S43, the powder hopper stays between the bean grinding assembly and the brewing assembly, reminding and waiting for the user to clean the coffee grounds.

[0037] The rotation of the powder hopper and the setting of the rotation time are completely completed automatically by the system. The system can automatically record the time T for the powder hopper to rotate from the initial position to the brewing position, and accurately calculate the time X for the powder hopper to rotate, that is, when the time from the initial position to the brewing position in the opposite direction is X, the powder hopper can be moved to the position between the grinding component and the brewing component, making it easier for users to clean the coffee grounds. This simple time control simplifies the overall control method of the coffee machine. Due to the improvement of automation and accuracy, this method can significantly improve the efficiency of coffee brewing. Users do not need to manually control the rotation time and position of the powder hopper, which saves time and improves the overall efficiency of brewing.

[0038] In any of the above technical solutions, step S5 includes the following specific steps:

[0039] S51, pour out the coffee grounds in the powder hopper;

[0040] S52, placing the powder hopper and receiving a powder hopper reset instruction;

[0041] S53: The powder hopper receives the reset instruction and continues to rotate and reset to the initial position.

[0042] By clearly completing the steps of emptying the grounds and placing the powder hopper, it can be ensured that the coffee grounds can be cleaned in time, ensuring the overall hygiene of the coffee machine. In addition, the powder hopper can automatically rotate and reset to the initial position after receiving the reset command, making the coffee brewing equipment more efficient when in use. Through the precise reset of the powder hopper and the standardization of user operations, the brewing process is simpler and easier to understand, reducing the user's learning cost.

[0043] A coffee machine comprises: a frame; a rotating motor, which is arranged on the frame; a bean grinding assembly, which is arranged on the frame and located on one side of the rotating motor; a brewing assembly, which is arranged on the frame and located on a side of the rotating motor away from the bean grinding assembly; a powder hopper, which is arranged on the rotating motor and can drive the powder hopper to rotate relative to the bean grinding assembly and the brewing assembly; and a control unit, which is arranged on the frame and is electrically connected to the rotating motor, the bean grinding assembly and the brewing assembly, respectively.

[0044] The second aspect of the present application discloses a coffee machine, which is electrically connected to a rotating motor, a bean grinding assembly, and a brewing assembly through a control unit, so that the coffee machine can realize functions such as automatic grinding and automatic brewing. The bean grinding assembly and the brewing assembly are respectively located on both sides of the rotating motor, and the powder hopper is arranged on the rotating motor. The rotating motor can drive the powder hopper to rotate and move to the bottom of the bean grinding assembly or the brewing assembly, thereby ensuring that the functions of automatic delivery of coffee powder and automatic brewing can be carried out stably, while improving the degree of automation of the coffee machine. In addition, the layout of the rotating motor, the powder hopper, the bean grinding assembly, and the brewing assembly on the frame makes the overall structure of the coffee machine more compact, optimizes the volume of the entire coffee machine, not only saves space, but also makes the appearance of the coffee machine more beautiful and generous.

[0045] In any of the above technical solutions, the control unit includes:

[0046] Control interface, used to display operation information and receive user instructions;

[0047] A processor for processing user instructions and controlling the workflow of the coffee machine;

[0049] The control interface can display operation information and receive user instructions, so that users can intuitively understand the operating status of the coffee machine, and can conveniently adjust various settings through the interface, thereby improving the user experience. As the core part of the control unit, the processor can quickly process user instructions and control the workflow of the coffee machine according to the instructions, so that the coffee machine can quickly respond to user operations and improve the efficiency of the coffee machine. The sensor is used to detect the position of the powder hopper and feed back the information to the processor. When it is detected that the powder hopper is directly below the grinding component, the automatic delivery process of the coffee powder can be ensured to be stable; when it is detected that the powder hopper is directly below the brewing component, the stability of the automatic brewing process can be ensured. Combining the control interface, processor and sensor, the coffee machine realizes intelligent control. Users can adjust the various parameters of the coffee machine through a simple operation interface, and the coffee machine can automatically complete the entire process of coffee preparation, including grinding and brewing, which greatly improves the automation of the coffee machine.
