Description

Technical Field

[0001] The present disclosure relates to the technical fields of coffee production and coffee electronic scales, and particularly to a real-time display method for the powder-to-water ratio of a weighing scale for hand-brewed coffee, a coffee electronic scale, a device, and a storage medium. Background Art

[0002] During the coffee brewing process, generally, the coffee powder is weighed first, and then the coffee powder is subjected to the brewing step. Specifically, according to the target powder-to-water ratio (or water-to-powder ratio) and the desired beverage volume, the required water injection volume is calculated in advance, and then the coffee powder is weighed, and water is injected according to the weight of the coffee powder and the target powder-to-water ratio. However, different types of coffee powders have different requirements for the powder-to-water ratio due to factors such as origin, roasting degree, and grinding fineness. Although the existing brewing methods calculate the water injection volume based on the target powder-to-water ratio set by the device or the target powder-to-water ratio prompted in the product manual, it is difficult to accurately match the optimal powder-to-water ratio of each type of coffee powder in actual operation. In addition, due to the inaccurate control of the powder-to-water ratio and the water injection volume, the taste of the brewed coffee may fluctuate greatly, resulting in a large difference between the taste of the brewed coffee and the expectation. Moreover, some coffee electronic scales on the market that support the display of the powder-to-water ratio cannot view the water-to-powder ratio in real time during coffee brewing, so the reliability of brewing is relatively low.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0040] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with reference to specific embodiments:

[0041] Please refer to Figure 1 , which is the real-time display method of the powder-water ratio of a weighing scale based on hand-brewed coffee in an embodiment of the present invention, including some or all of the following steps:

[0042] S101. Obtain and record the weighing value in real time; in this embodiment, the above-mentioned weighing value is the weight when coffee powder is put in, that is, the value weighed in the standby state is the weight of the coffee powder. Specifically, when the coffee electronic scale is powered on and in the standby state, the obtained weighing value is defaulted to the powder weight, and it is obtained and recorded in real time through the weighing value, making prior preparations for obtaining the powder-water ratio value.

[0043] S102. Receive the ratio calculation start instruction and temporarily store the current weighing value as the powder weight value. In this embodiment, the ratio calculation start instruction can be expressed as a command to start and calculate the water-powder ratio. When this command is received, the function of calculating the water-powder ratio is started, and preparations are made in advance to display the current water-powder ratio. In addition, after receiving this command, it enters the working state. The weighing value obtained in the standby state is stored in the memory and defined as the powder weight value. Subsequently, the weight of the weighing water is defaulted to make further preparations for obtaining the water-powder ratio.

[0044] S103. Obtain the water weight value according to the preset sampling period. The powder weight value and the water weight value are used to calculate the water-powder ratio according to the functional relationship of the water-powder ratio. In the embodiment, when the ratio calculation start instruction is received, the default weighed value is the water weight value instead of being recorded as the powder weight value. At this time, the weighing module will periodically obtain the water weight value, combine the changing water weight value with the powder weight value obtained in the standby state, and obtain the water-powder ratio through the functional relationship. Among them, the powder weight value is a constant, the water weight value is an independent variable, and the water-powder ratio is a dependent variable.

[0045] S104. Update and display the water-powder ratio at the end of each sampling period. It can be understood that after obtaining the water-powder ratio through the functional relationship, it will be displayed in the form of the display screen of the coffee electronic scale. Moreover, since the powder weight value is already a fixed value and the water weight value is variable, the water-powder ratio obtained through the functional relationship is variable. Thus, the displayed water-powder ratio is updated after one sampling period and the new value is displayed. That is to say, the displayed water-powder ratio is variable and changes periodically with the value calculated through the functional relationship, which can achieve the effect of real-time updating and displaying the water-powder ratio.

[0046] In this embodiment, when the coffee electronic scale does not receive the start instruction, the powder weight value is defaultly collected. When the start instruction is received, the water weight value is defaultly collected. At the same time, the powder weight value and the water weight value are calculated through the functional relationship to obtain the water-powder ratio, and the current value is displayed on the display screen of the coffee electronic scale. When the water injection operation is performed, the coffee electronic scale will update and display the water-powder ratio at the end of each sampling period, so as to realize real-time viewing of the water-powder ratio, ensure the precise control between the powder weight and the water weight, and further ensure the taste when making coffee.

[0047] In one of the embodiments, when executing S102, it specifically includes the following steps: Receive the ratio calculation start instruction and the tare instruction, and temporarily store the current weighing value as the powder weight value. In this way, before the weighing module obtains the water weight value in real time, the weighing value is stored, and at the same time, the tare process is performed, that is, the weight value is reset to zero to prevent the interference of other substances from affecting the accuracy of the weighing module in obtaining the water weight value.

[0048] In one embodiment, the functional relationship of the water-to-powder ratio satisfies the following relational expression: water-to-powder ratio value = M1 / M2, where M1 is defined as the weight value of water and M2 is defined as the weight value of powder. It can be understood that when the ratio calculation start instruction is not received, the weight of the ground coffee is default weighed. When the ratio calculation start instruction is received, the weight of water is default weighed. At the moment of receiving the instruction, the weight of the ground coffee has been recorded in the memory as the powder weight value, and the powder weight value will no longer change due to subsequent steps. Furthermore, when the water weight value is obtained in real time, the calculation module calculates the ratio of the water weight value and the powder weight value to obtain the water-to-powder ratio value. At this time, the water-to-powder ratio value changes with the change of the water weight value and is reflected by the functional relationship. Among them, the powder weight value belongs to a constant, the water weight value belongs to an independent variable, and the water-to-powder ratio value belongs to a dependent variable. For example, when the ratio calculation start instruction is not received, the weight value obtained by the weighing module is 20g, and this value represents the powder weight value M2 = 20g. Subsequently, the ratio calculation start instruction is received to switch to another weighing state. In this state, the weight value obtained by the weighing module is 300g, and this value represents the water weight value M1 = 300g. The original weight, that is, the powder weight value, is already a determined value. Through function calculation, according to the relational expression: water-to-powder ratio value = M1 / 20, the water-to-powder ratio value can be calculated to be 15. However, the water weight value M1 is a variable value and will be updated once every sampling period. For example, the water weight value M1 read in the previous period is 296g, the water weight value M1 read in the next period is 300g, and the water weight value M1 read in the next subsequent period is 302g. In this way, the water-to-powder ratio value displayed by the display module will also change accordingly in the corresponding period, that is, the water-to-powder ratio value displayed in the previous period is 14.8, the water-to-powder ratio value displayed in the next period is 15.0, and the water-to-powder ratio value displayed in the next subsequent period is 15.1. In this way, the displayed water-to-powder ratio value will be calculated according to the functional relationship and updated at the end of each period, playing a role of real-time display.

[0049] As Figure 2 shown, when water is injected after the powder placing operation is completed, the coffee electronic scale real-time displays the current powder-to-water ratio and the water weight value. The water weight value is displayed in the weight value display area. For example, M2 = 20g, M1 = 300g, and the calculated powder-to-water ratio is 1:15, and M1 and the powder-to-water ratio are real-time variable. Of course, the coffee electronic scale can also real-time display the water-to-powder ratio, that is, the water-to-powder ratio value is 15.0. Here, it is convenient for those skilled in the art to understand the implementation principle of the coffee electronic scale, rather than limiting the display effect function of the coffee electronic scale.

[0050] In one embodiment, when executing S103, the range of the preset sampling period is 300 - 500ms. In this embodiment, the sampling period value is 400ms.

[0051] In one embodiment, when performing S103, the following steps are further included: obtaining a start time value according to a timing period, and calculating a water flow rate value based on the water weight value and the start time value according to a water flow rate function relationship. In this embodiment, in the initial state without receiving a ratio calculation start instruction, the coffee electronic scale is in a standby state, and the weighing module defaults to weighing the powder weight. At this time, no timing is performed to distinguish the standby state and the working state. Furthermore, the powder weight value is obtained in real time without timing, rather than the water weight value. After receiving the ratio calculation start instruction, timing begins. At this time, the weighing module defaults to weighing the water weight. The water weight value and the start time value will be reflected by the water flow rate function relationship. The degree of inclination of the straight line formed in the coordinate axis with respect to the coordinate axis represents the water flow rate value, so as to better confirm the rate during water injection. Further, the start time value is updated and displayed at the end of each timing period to better distinguish the state of the coffee electronic scale. Further, the water flow rate value is also updated and displayed at the end of each sampling period to better output the current data and inform the user.

[0052] In one embodiment, a start time value is obtained according to a timing period, and a water flow rate value is calculated based on the water weight value and the start time value according to a water flow rate function relationship. After that, the following steps are further included:

[0053] Periodically detect whether the water flow rate value is less than or equal to a stop speed threshold;

[0054] When the water flow rate value is less than or equal to the stop speed threshold, obtain a closing delay value;

[0055] Detect whether the closing delay value is greater than or equal to a closing threshold;

[0056] When the closing delay value is greater than or equal to the closing threshold, output the current water-to-powder ratio.

[0057] In this embodiment, the stop speed threshold represents the water flow speed value at which the water weight value changes very little or does not change within a certain period of time. For example, the stop speed threshold is 0.1 g / s. When receiving the ratio calculation start instruction, the water weight value is default measured. When the water weight values obtained in any two adjacent periods are different and the absolute difference between them is greater than the preset weight difference. Specifically, when the value obtained in the latter period is greater than the preset weight difference, such as 0.1 g, from the value obtained in the previous period, the water flow speed value calculated by the function is greater than the stop speed threshold; when the water weight values obtained in any two adjacent periods are the same or similar, that is, when the value obtained in the latter period is less than or equal to the preset weight difference from the value obtained in the previous period, the water flow speed value calculated by the function is less than or equal to the stop speed threshold, then the timing for shutdown delay starts, so that when the water flow speed value is obtained, the water flow speed value is compared with the stop speed threshold value to confirm whether to continue executing S103 or start the timing for shutdown delay. Further, the shutdown threshold represents the critical value for entering the stop timing state. For example, the critical value is 15 seconds. When the timing for shutdown delay continues until the critical value and the absolute difference between the water weight values obtained by the weighing module in any two adjacent periods is less than the preset weight difference, the final water-to-powder ratio is output. Further, the user is informed through screen flashing, indicator light flashing or beeping to confirm the final water-to-powder ratio, so as to achieve the effect of real-time displaying the water-to-powder ratio while accurately outputting the water-to-powder ratio, thereby achieving the effect of precise control and reducing the error from the target water-to-powder ratio. Further, it is detected whether the shutdown delay value is greater than or equal to the shutdown threshold, and the following steps are further included: when the shutdown delay value is less than the shutdown threshold, S103 is continued to be executed. It can be understood that within the time interval from the start of the timing for shutdown delay to the shutdown threshold, the steps of obtaining the water weight value and calculating the ratio of the water weight value to the powder weight value are still executed. At this time, the timing for shutdown delay is normal. When at the end of the current shutdown delay, the water flow speed value obtained through the water flow speed function relationship is greater than the stop speed threshold, it indicates that the absolute difference between the water weight values obtained by the weighing module in any two adjacent periods is greater than the preset weight difference, so the timing for shutdown delay is stopped, and then the current water-to-powder ratio is continuously obtained and periodically updated and displayed. In this way, during coffee brewing, a one-time water injection operation can be realized, or a multi-stage water injection operation can be realized, that is, after a period of water injection, it is paused for a certain time, and then the next stage of water injection operation is carried out.

[0058] Further, periodically detect whether the water flow rate value is equal to the stop speed threshold, and the following steps are further included: when the water flow rate value is greater than the stop speed threshold, continue to execute S103. It can be understood that after obtaining the slope, that is, the water flow rate value, through the water flow rate function relationship, the current water flow rate value is numerically compared with the stop speed threshold. When the water flow rate value is greater than the stop speed threshold, it means that the absolute difference between the water weight values obtained by the weighing module in any two adjacent cycles is greater than the preset weight difference. Therefore, the powder-water ratio value is calculated based on the powder weight value and the water weight value, and the current powder-water ratio value is displayed through the display module, that is, S103 is normally executed, so as to display the powder-water ratio value in real time when the coffee electronic scale is working normally. At this time, stop timing and turn off the delay.

[0059] The present disclosure also provides a coffee electronic scale, which has an electronic control panel. The electronic control panel includes a start control module, a weighing module, a recording module, a calculation module and a display module. The start control module is used to receive and respond to the ratio calculation start instruction; the weighing module is used to obtain and record the weighing value in real time, and obtain the water weight value according to the preset sampling period when receiving the ratio calculation start instruction; the recording module is used to temporarily store the current weighing value as the powder weight value when receiving the ratio calculation start instruction; the calculation module is used to obtain the water weight value according to the preset sampling period, and the powder-water ratio value is calculated based on the powder weight value and the water weight value according to the powder-water ratio function relationship; the display module is used to update and display the powder-water ratio value at the end of each sampling period.

[0060] In the above embodiment, when the coffee electronic scale does not receive the start instruction, the powder weight value is default collected. When the start instruction is received, the water weight value is default collected. At the same time, the powder weight value and the water weight value are calculated and processed by the function relationship to obtain the powder-water ratio value, and the current value is displayed on the display screen of the coffee electronic scale. When the water injection operation is performed, the coffee electronic scale will update and display the powder-water ratio value at the end of each sampling period, so as to realize real-time viewing of the powder-water ratio value, ensure precise control between the powder weight and the water weight, and further ensure the taste of the coffee during brewing.

[0061] During the process of brewing coffee, generally, the coffee powder is first placed on the filter cup with filter paper, and then water is injected through the wall of the filter cup. However, some users make operation mistakes when injecting water, so that a part of the water does not enter the coffee container through the filter cup, but leaks outside to the coffee electronic scale. In this way, the water weight value weighed by the weighing module includes the sum of the weight of the water in the coffee container and the weight of the leaked water, which makes the target powder-water ratio different from the displayed powder-water ratio. Further, even if the powder-water ratio value displayed by the display module matches the target powder-water ratio, the actual powder-water ratio value is smaller than the target powder-water ratio. Furthermore, the taste of the brewed coffee still differs from the expected coffee taste, affecting the user experience.

[0062] To ensure that the displayed water-powder ratio matches the target water-powder ratio, after executing S102, some or all of the following steps are included:

[0063] Receive the water scraping start instruction and collect the water scraping weighing value;

[0064] Based on the water scraping water-powder ratio function relationship, the water scraping water-powder ratio value is calculated from the water scraping weighing value, the water weight value, and the powder weight value;

[0065] Update and display the water scraping water-powder ratio value at the end of each sampling period.

[0066] It can be understood that when receiving the ratio calculation start instruction, the water weight value is collected by default, and this water weight value is the sum of the weight of the water in the coffee container and the weight of the water leaking outside. After receiving the water scraping start instruction, the weighing module will also collect the weight value of the water leaking outside, denoted as the water scraping weighing value. Among them, the water scraping weight value can be expressed as the weight value of the water leaking outside on the coffee electronic scale. After determining the water weight value and the water scraping weight value, the two are used together with the powder weight value to calculate the water scraping water-powder ratio value through a function, and this water scraping water-powder ratio value is displayed in real time. The water scraping water-powder ratio value is updated every other sampling period to eliminate the calculation interference caused by the water leaking outside the coffee container during water injection, thereby reducing the error between the water-powder ratio value when brewing coffee and the target water-powder ratio.

[0067] Furthermore, the calculation functional relationship of the water-powder ratio for water drainage satisfies the following relational expression: water-powder ratio for water drainage = (M1 - M3) / M2, where M3 is defined as the weighed value of drained water and belongs to the independent variable, and the water-powder ratio for water drainage is defined as the specific water-powder ratio excluding the factor of water leakage. It can be understood that when receiving the ratio calculation start instruction, the water weight value is obtained by default. At this time, the obtained value includes the water weight value in the coffee container and the water weight value of the leakage, so there will be a difference between the water-powder ratio obtained from the water weight value and the powder weight value and the target water-powder ratio. Therefore, when receiving the water drainage start instruction, the weighing module will also obtain in real time the water weight value of the leakage on the coffee electronic scale, that is, the weighed value of drained water. In this way, by subtracting the weighed value of drained water from the water weight value, the water weight value within the coffee capacity can be obtained. Subsequently, by performing a ratio calculation on this value and the powder weight value, the water-powder ratio for water drainage can be obtained, thereby further reducing the gap between this water-powder ratio and the target water-powder ratio for coffee brewing, making the obtained water-powder ratio match the target water-powder ratio. For example, the powder weight value M2 = 20g. When receiving the ratio calculation start instruction, the weighing module obtains the weight value M1 = 300g, and this weight value includes the water weight value in the coffee container and the water weight value of the leakage, that is, there is some water leakage on the coffee electronic scale. In this case, the obtained water-powder ratio is 15, which results in a situation where the value on the display module is larger than the actual water-powder ratio; when receiving the water drainage start instruction, the weighing module will also weigh the water weight value of the leakage, denoted as M3 = 10g. In this way, by subtracting the water weight value M1 and the weighed value of drained water M3, and then performing a ratio calculation with the powder weight value, the water-powder ratio for water drainage can be obtained, that is, (M1 - M3) / M2 = 14.5, and the water-powder ratio for water drainage is displayed in real time, so as to confirm whether the water-powder ratio for water drainage matches the target water-powder ratio, further reducing the numerical error caused by water injection leakage.

[0068] Furthermore, the coffee electronic scale has a water leakage catchment area. The start control module of the electronic control panel is further configured to receive and respond to the water drainage start instruction; the weighing module of the electronic control panel is further configured to collect the weighed value of drained water located in the water leakage catchment area when receiving the water drainage start instruction; the calculation module of the electronic control panel is further configured to calculate the water-powder ratio for water drainage based on the weighed value of drained water, the water weight value, and the powder weight value according to the water-powder ratio function relationship for water drainage; the display module is configured to update and display the water-powder ratio at the end of each sampling period when receiving the ratio calculation start instruction, and update and display the water-powder ratio for water drainage at the end of each sampling period when receiving the water drainage start instruction.

[0069] It can be understood that the external leakage catchment area can be a catchment ring groove. When some water is accidentally spilled during water injection, the water on the outer wall of the coffee container and the water on the coffee electronic scale will be introduced into the catchment ring groove, so that the weighing module can obtain the water weight value in the catchment ring groove, and then it is convenient to perform a subtraction algorithm on the original water weight value and the water weight value in the catchment ring groove to finally confirm the actual water weight value, that is, the water weight value in the coffee container, so as to confirm the final water-to-powder ratio, so as to play a role in excluding the interference caused by water spillage and further reduce the error between the water-to-powder ratio and the target water-to-powder ratio.

[0070] In addition, in the case of receiving the ratio calculation start instruction, the water weight value is default weighed, and the weighing module obtains the water weight value in real time. During water injection, every time a collection period passes, the water weight value obtained by the weighing module shows an upward trend. Furthermore, the water-to-powder ratio calculated from the water weight value and the powder weight value also shows an upward trend with this cycle. When the user is injecting water, they may ignore the water-to-powder ratio on the display screen. As the water-to-powder ratio rises with the increase of the water injection volume, there may be a situation where the water-to-powder ratio exceeds the expected water-to-powder ratio, resulting in a lighter taste of the brewed coffee compared to the expected taste, causing material waste and thus affecting the user's operation experience.

[0071] To ensure that the water-to-powder ratio can reach the expected water-to-powder ratio on time, when executing S102, the following steps are also included: receiving the water-to-powder ratio threshold setting instruction; and

[0072] After executing S104, the following steps are also included:

[0073] According to the comparison period, detect whether the water-to-powder ratio is greater than the water-to-powder ratio threshold;

[0074] If the water-to-powder ratio is greater than or equal to the water-to-powder ratio threshold, output an alarm message.

[0075] In this embodiment, when the coffee electronic scale is in the startup state, if it does not receive the water-to-powder ratio threshold setting instruction, it means that the water-to-powder ratio threshold is not set; if it receives the water-to-powder ratio threshold setting instruction, it means that the water-to-powder ratio threshold is determined, and the current water-to-powder ratio value is compared with this water-to-powder ratio threshold. Specifically, in the case of not receiving the water-to-powder ratio threshold setting instruction, when the water weight value obtained by the weighing module increases every cycle, the water-to-powder ratio value calculated by function also increases with this cycle, and no comparison is made at this time; in the case of receiving the water-to-powder ratio threshold setting instruction, the calculated water-to-powder ratio value will be periodically output on the display screen, and at the same time, the obtained water-to-powder ratio value is compared with the set water-to-powder ratio threshold, and a comparison is made every comparison cycle until the water-to-powder ratio value reaches the water-to-powder ratio threshold, and an alarm message is sent, and the user is informed by digital display flashing or beeping, preventing the user from continuing to inject water, thereby preventing the situation that the brewing taste is too light caused by over-injection of water, and then ensuring the taste and quality of coffee brewing and the operation experience of the user. For example, after completing the acquisition of the powder weight value, the water-to-powder ratio threshold is set to 16.0, and then the acquisition of the water weight value starts. When the water weight value obtained in each cycle increases, the corresponding water-to-powder ratio value also increases with this cycle, and the water-to-powder ratio value displayed on the display screen increases with this cycle until the displayed water-to-powder ratio value is 16.0, and the user is informed by digital display flashing or beeping. In this embodiment, the range of the comparison cycle is 150 - 250 ms, for example, the comparison cycle is 200 ms.

[0076] In another embodiment, it is detected whether the water-to-powder ratio value is greater than the water-to-powder ratio threshold, and then it further includes: if the water-to-powder ratio value is less than the water-to-powder ratio threshold, S104 is executed. In this way, when it is detected that the water-to-powder ratio value does not reach the set water-to-powder ratio threshold, the step of updating and displaying the current water-to-powder ratio value at the end of the sampling cycle can be executed, and at the same time, the current water-to-powder ratio value is normally compared with the water-to-powder ratio threshold, and no alarm message is output, which also indicates that the weighing module continues to periodically acquire the current water weight value, so that the water weight value and the powder weight value are used to calculate the powder-to-water ratio value, further indicating that the user can continue the water injection operation until the water-to-powder ratio value output on the display screen is equal to the set water-to-powder ratio threshold.

[0077] Furthermore, the electronic control panel further includes a water-to-powder ratio input module, a comparison module and an alarm module. The water-to-powder ratio input module is used to receive the water-to-powder ratio threshold setting instruction, the comparison module is used to detect whether the water-to-powder ratio value is greater than the water-to-powder ratio threshold in the case of receiving the water-to-powder ratio threshold setting instruction, and the alarm module is used to respond to the alarm message in the case of the water-to-powder ratio value being greater than or equal to the water-to-powder ratio threshold.
