Description

[0001] The present invention relates to the technical field of coffee grinders, and in particular, to a method, device, electronic device and storage medium for grinding beans. Background Art

[0002] With the improvement of living standards, coffee grinders are increasingly widely used. Coffee grinders can be used to grind granular foods such as coffee beans and soybeans into powder. In order to meet the user's demand for the powder output weight of the coffee grinder, a weighing sensor is provided below the powder container for holding powder in the coffee grinder. When the weighing value of the weighing sensor reaches the powder output weight required by the user, a stop signal is sent to the motor in the coffee grinder through the CPU to stop the coffee grinder from grinding beans.

[0003] However, when the weighing value of the weighing sensor reaches the powder output weight required by the user, the residual powder in the powder collection pipe of the coffee grinder does not fall into the powder container, and the motor will not stop immediately after receiving the stop information. The residual kinetic energy will continue to grind out powder, resulting in the actual powder output weight of the coffee grinder being greater than the powder output weight required by the user.

[0057] It should be noted that the term "including" will be used in the embodiments of this application to indicate the existence of the features stated thereafter, but does not exclude adding other features.

[0058] The following provides a detailed description of a coffee grinding method provided by the embodiments of this application.

[0059] Refer to Figure 1 As shown, it is a schematic flowchart of a coffee grinding method provided by the embodiments of this application. The specific execution process of this coffee grinding method is as follows:

[0060] S101. Obtain the first coffee grinding rate and the total powder output set by the user.

[0061] S102. Determine the coffee grinding duration corresponding to the second coffee grinding rate according to the first coffee grinding rate.

[0062] S103. When the coffee grinding rate of the coffee grinder reaches the first coffee grinding rate, judge whether to start grinding coffee at the second coffee grinding rate based on the first coffee grinding rate, the total powder output, the remaining powder amount in the pipeline corresponding to the second coffee grinding rate, and the remaining kinetic energy powder amount at the current powder output weight of the weighing sensor.

[0064] S105. Otherwise, continue to grind coffee at the first coffee grinding rate, and jump to judge whether to start grinding coffee at the second coffee grinding rate based on the current powder output weight of the weighing sensor to continue execution.

[0065] The embodiments of the present application provide a method, device, electronic device, and storage medium for grinding beans. The method for grinding beans includes: obtaining a first grinding rate and a total powder output set by a user; determining a grinding duration corresponding to a second grinding rate according to the first grinding rate; the second grinding rate is a preset grinding rate corresponding to a known remaining powder amount in the pipeline and a remaining kinetic energy powder amount; when the grinding rate of the bean grinder reaches the first grinding rate, determine whether to start grinding at the second grinding rate based on the first grinding rate, the total powder output, the remaining powder amount in the pipeline corresponding to the second grinding rate, and the remaining kinetic energy powder amount under the current powder output weight of the weighing sensor; if starting to grind at the second grinding rate, grind at the second grinding rate and send a stop signal to the motor after the grinding duration; otherwise, continue to grind at the first grinding rate and jump to determine whether to start grinding at the second grinding rate under the current powder output weight of the weighing sensor to continue execution. In the present application, when the grinding rate of the bean grinder reaches the first grinding rate, it is determined whether to start grinding at the second grinding rate based on the current powder output weight of the weighing sensor; if starting to grind at the second grinding rate, send a stop signal to the motor after grinding at the second grinding rate for the grinding duration; otherwise, continue to determine whether to start grinding at the second grinding rate. The present application enables the bean grinder to grind beans, and the actual powder output weight of the bean grinder is equal to the total powder output required by the user.

[0066] The following describes the exemplary steps of the embodiments of the present application:

[0067] S101. Obtain the first grinding rate and the total powder output set by the user.

[0068] In the embodiment of the present application, the first grinding rate is the grinding rate of the bean grinder set by the user. The total powder output is the weight of the powder that the user sets for the bean grinder to grind.

[0069] Here, the powder produced after the motor of the bean grinder grinds first enters one end of the powder collection pipeline and then flows out from the other end of the powder collection pipeline and falls into the powder storage container. In addition, a weighing sensor is provided below the powder storage container to weigh the powder in the powder storage container.

[0070] S102. Determine the grinding duration corresponding to the second grinding rate according to the first grinding rate.

[0071] In the embodiment of the present application, the second grinding rate is the second grinding rate preset by the technician in advance. The residual powder amount in the pipeline refers to the weight of the powder that has been ground by the motor but has not fallen into the powder container yet when grinding continues at the second grinding rate. The kinetic energy residual powder amount refers to the weight of the powder ground due to the kinetic energy brought by the current rotation speed of the motor after sending a signal to stop grinding to the motor when grinding at the second grinding rate. The grinding duration is used to specify the duration of grinding at the second grinding rate during the current grinding.

[0072] Here, when finally sending a stop signal to the motor, if the residual powder amount in the pipeline and the kinetic energy residual powder amount of the grinder are known at this time, it can be ensured that the actual powder output weight of the grinder finally is equal to the total powder output preset by the user; therefore, the second grinding rate must be the grinding rate corresponding to the known residual powder amount in the pipeline and the kinetic energy residual powder amount.

[0073] Specifically, determine the difference between the first grinding rate and the second grinding rate.

[0074] In the embodiment of the present application, subtract the second grinding rate from the first grinding rate to obtain the difference in the rates between the first grinding rate and the second grinding rate.

[0075] Specifically, determine the grinding duration according to the difference and the second grinding rate.

[0076] In the embodiment of the present application, it takes time from sending a signal to the motor to the motor executing the signal content. Therefore, we preset a preset duration in advance. If we continue to grind at the first grinding rate, then after the preset duration, a stop signal should be sent to the motor so that the actual powder output weight of the grinder finally is equal to the total powder output preset by the user. However, in order to know the residual powder amount in the pipeline and the kinetic energy residual powder amount of the grinder when sending a stop signal to the motor, the grinding is changed to be carried out at the second grinding rate. However, due to the speed difference between the first grinding rate and the second grinding rate, the weights of the powder ground by the two in the same duration are different. Therefore, it is necessary to calculate how long the grinding duration of the second grinding rate should be to ensure that the powder output in the preset duration is the same after converting the first grinding rate to the second grinding rate. It can be seen from the above that the powder output when grinding for the preset duration at the first grinding rate is the same as the powder output when grinding for the above-mentioned grinding duration at the second grinding rate.

[0077] Further, first calculate the product of the difference and the preset duration to obtain the weight difference of the ground powder corresponding to the first grinding rate and the second grinding rate within the preset duration. Then calculate the ratio of this product to the second grinding rate, and this ratio is the duration required for the coffee grinder to grind out the same weight of powder as the value of the weight difference at the second grinding rate. Finally, calculate the sum of this ratio and the preset duration to obtain the duration for the coffee grinder to grind at the second grinding rate.

[0078] Optionally, the above calculation process of the grinding duration can also be expressed by the following formula:

[0079] T = At 0 / v 2 + 0 ;

[0080] where T is the grinding duration, A is the difference between the first grinding rate and the second grinding rate, t 0 is the preset duration, and V 2 is the second grinding rate.

[0081] S103. After the grinding rate of the coffee grinder reaches the first grinding rate, determine whether to start grinding at the second grinding rate based on the first grinding rate, the total powder output, the remaining powder amount in the pipeline corresponding to the second grinding rate, and the remaining powder amount of kinetic energy at the current powder output weight of the weighing sensor.

[0082] Determine whether to start grinding at the second grinding rate at the current powder output weight of the weighing sensor through the following steps:

[0083] I. Determine the target powder output weight based on the first grinding rate, the total powder output, the remaining powder amount in the pipeline, and the remaining powder amount of kinetic energy.

[0084] In the embodiment of the present application, the target powder output weight is used to represent the value of the weighing sensor when the coffee grinder starts to grind at the second grinding rate. That is, when the weight of the powder container is the same as the target powder output weight, the coffee grinder starts to grind at the second grinding rate.

[0085] Specifically, the method for determining the target powder output weight includes: determining the initial powder output weight ground at the first grinding rate for the preset duration; calculating the sum of the initial powder output weight, the remaining powder amount in the pipeline, and the remaining powder amount of kinetic energy; subtracting the sum from the total powder output to obtain the target powder output weight.

[0086] In the embodiment of the present application, the product of the first grinding rate and the preset duration is determined as the initial powder output weight.

[0087] Here, the sum value of the initial powder output weight, the remaining powder amount in the pipeline, and the remaining powder amount due to kinetic energy is the sum value of the powder output amount when the coffee grinder grinds for a preset duration at the second grinding rate, the weight of the powder that has been ground but has not yet fallen into the powder container after sending a stop signal to the motor, and the weight of the powder continuously ground by the kinetic energy brought by the current rotation speed of the motor. Subtracting the sum value from the total powder output amount gives the value of the weighing sensor when the coffee grinder starts grinding at the second grinding rate.

[0088] II. By comparing the target powder output weight and the current powder output weight, determine whether to start grinding at the second grinding rate.

[0089] In the embodiment of the present application, the current powder output weight is the value of the weighing sensor. The value of the weighing sensor is the weight of the powder in the powder container.

[0090] Specifically, if the target powder output weight is the same as the current powder output weight, start grinding at the second grinding rate.

[0091] S104. If starting to grind at the second grinding rate, grind at the second grinding rate and send a stop signal to the motor after the grinding duration.

[0092] S105. Otherwise, continue to grind at the first grinding rate and jump to determine whether to start grinding at the second grinding rate based on the current powder output weight of the weighing sensor to continue execution.

[0093] Refer to Figure 2 As shown, it is a flowchart of a coffee grinding method provided by an embodiment of the present application. For the similarities between steps S201 to S207 and steps S101 to S105, refer to steps S101 to S105 and will not be repeated here. The following is an explanation of the exemplary steps of the embodiment of the present application:

[0094] S201. Obtain the first grinding rate and the total powder output amount set by the user.

[0095] S202. Determine whether the first grinding rate is the same as the second grinding rate.

[0096] S203. If the first grinding rate is the same as the second grinding rate, set the grinding duration to zero and jump to determine whether to start grinding at the second grinding rate based on the current powder output weight of the weighing sensor to continue execution.

[0097] In the embodiment of the present application, if the first grinding rate is the same as the second grinding rate, it means that there is no speed difference between the two, so there is no need to consider the duration of changing from the first grinding rate to the second grinding rate, and there is no need to calculate the grinding duration of the second grinding rate. Just set the grinding duration to zero directly.

[0098] S204. If the first grinding rate is different from the second grinding rate, determine the grinding duration corresponding to the second grinding rate according to the first grinding rate.

[0099] S205. After the grinding rate of the grinder reaches the first grinding rate, determine whether to start grinding at the second grinding rate based on the current powder output weight of the weighing sensor according to the first grinding rate, the total powder output, the remaining powder amount in the pipeline corresponding to the second grinding rate, and the remaining kinetic energy powder amount.

[0100] S206. If starting to grind at the second grinding rate, grind at the second grinding rate and send a stop signal to the motor after the grinding duration.

[0101] S207. Otherwise, continue to grind at the first grinding rate, and jump to determine whether to start grinding at the second grinding rate based on the current powder output weight of the weighing sensor to continue execution.

[0102] An embodiment of the present application provides a grinding method, which includes: obtaining the first grinding rate and the total powder output set by the user; determining whether the first grinding rate is the same as the second grinding rate; if the first grinding rate is the same as the second grinding rate, set the grinding duration to zero and jump to determine whether to start grinding at the second grinding rate based on the current powder output weight of the weighing sensor to continue execution; if the first grinding rate is different from the second grinding rate, determine the grinding duration corresponding to the second grinding rate according to the first grinding rate; the second grinding rate is a preset grinding rate corresponding to the known remaining powder amount in the pipeline and the remaining kinetic energy powder amount; after the grinding rate of the grinder reaches the first grinding rate, determine whether to start grinding at the second grinding rate based on the current powder output weight of the weighing sensor according to the first grinding rate, the total powder output, the remaining powder amount in the pipeline corresponding to the second grinding rate, and the remaining kinetic energy powder amount; if starting to grind at the second grinding rate, grind at the second grinding rate and send a stop signal to the motor after the grinding duration; otherwise, continue to grind at the first grinding rate, and jump to determine whether to start grinding at the second grinding rate based on the current powder output weight of the weighing sensor to continue execution. The present application determines different grinding methods by judging whether the first grinding rate is the same as the second grinding rate. The present application can enable the grinder to grind, and the actual powder output weight of the grinder is equal to the total powder output required by the user.

[0103] Based on the same inventive concept, an embodiment of the present application also provides a grinding device corresponding to the grinding method.
