[0073] In order to enable ordinary persons in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0074] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0075] The following describes a control method, a control device, an electronic device, and a storage medium for a water outlet device according to an embodiment of the present invention with reference to the accompanying drawings.

[0076] Before introducing the control method of the water outlet device of the present invention, let's first summarize two mainstream control schemes of the water outlet device in the related art:

[0077] The first option is to equip the water outlet device with a flow meter.

[0078] After the user sets the target capacity, the water outlet device starts the water pump to start discharging water. This solution calculates the time required for water discharging by the amount of water measured by the flow meter every revolution, and stops discharging water after the preset time is reached. However, this flow meter-based control method has several factors that affect accuracy:

[0079] a) Changes in water temperature have a significant effect on water density. For example, the density of water is 998 ml / L at 20°C, while it drops to 960 ml / L at 100°C. This difference results in a deviation of about ±4% under the two working conditions, or an error of about ±40 mL.

[0080] b) Assembly errors of the flow meter's internal components, dimensional changes of components at different temperatures, and dirt accumulated on the inner wall of the water pipe after long-term use will significantly affect the accuracy of the water output, causing the water output to gradually decrease and fail to meet users' expectations for accurate water output.

[0081] The second option is to use a water outlet device equipped with an electronic scale.

[0082] After the user sets the target capacity, the water outlet device starts the water pump to start discharging water, and uses the electronic scale to provide real-time feedback on the water volume. When the target capacity is reached, the water outlet stops. However, this control method based on electronic scales also has some obvious problems:

[0083] a) If the user does not start the water discharge before placing the cup on the electronic scale, the water discharge device will control the water discharge according to the preset time, resulting in a large deviation in the water discharge volume, which may exceed 30%.

[0084] b) When there is steam or air in the water pipe, resulting in poor water flow, even if the water outlet device stops discharging water after exceeding the set time by about 30%, the water output at this time is still far below the set target capacity.

[0085] c) Air or steam in the water outlet pipe may also cause unstable water output, resulting in jumps and sudden changes in the water volume data measured by the electronic scale, affecting the accuracy of the water output and bringing a bad experience to users.

[0086] d) During the normal water output process, although the electronic scale can measure the water output in real time and transmit the data to the control chip, there is a time delay and a delay in the flow of water in the pipe. If the conversion process is not performed, these delays will have a significant impact on the control of the water volume, resulting in a large deviation in the water output and failure to meet the demand for accurate water output.

[0087] To this end, the present invention proposes an innovative water outlet equipment control method, which corrects the reference water outlet flow rate at least once, determines the target duration based on the corrected reference water outlet flow rate and the target water outlet, and controls the water outlet equipment according to the target duration, thereby improving the water outlet accuracy of the water outlet equipment.

[0088] Figure 1 is a flow chart of a method for controlling a water outlet device according to an embodiment of the present invention.

[0089] It should be noted that the water outlet device in the embodiment of the present invention may be a water dispenser, a coffee machine, a tea machine, etc.

[0090] like Figure 1 As shown, the control method of the water outlet device in the embodiment of the present invention includes:

[0091] S1: After receiving a start instruction including a target water output M, the water output device is controlled to start outputting water.

[0092] S2: Get the set time period T.

[0093] S3: When the water outlet duration t reaches the set time period T, the corresponding actual water outlet volume m is obtained, and the expected water outlet volume M' is calculated according to the reference water outlet flow Q of the water outlet device and the set time period T.

[0094] In this embodiment, the reference water flow rate Q is determined by the following steps: First, an electronic scale is used to obtain the weight of an object of known weight, such as a weight, as the standard weight value m. 标 ; Then, measure the actual water discharge time t3 required for the water discharge device to discharge water to the standard weight value; Finally, according to the standard weight value m 标 And the actual water discharge time t3, calculate the reference water discharge flow Q, Q = m 标 / t3.

[0095] In front of the water outlet device, the user places the water receiving container on the water receiving tray where the electronic scale of the water outlet device is located, and starts the zeroing procedure to ensure that the electronic scale reading is zero. The user sets the water outlet target capacity, such as 500ml, through the touch screen or button, and issues a start command. The water outlet device immediately starts to discharge water and converts the target capacity into the target water outlet volume M.

[0096] The water outlet device sets a time window such as a set period T (such as 2 seconds) to measure the actual water output after the water outlet starts. Within the set period T, the water outlet device records the weight of the actual water output through a built-in electronic scale, and when the water outlet time t reaches the set period T1, the corresponding actual water output m is obtained, and the expected water output M' is calculated based on the reference water outlet flow Q of the water outlet device and the set period T, M'=Q*T.

[0097] S4: Correct the reference water flow rate Q according to the difference between the actual water flow rate m and the expected water flow rate M'.

[0098] First, the expected water output range is determined according to the expected water output M' and the set deviation water output m', such as 3g. Among them, the lower limit of the expected water output range is the difference between the expected water output M' and the set deviation water output m', that is, M'-m', and the upper limit of the expected water output range is the sum of the expected water output M' and the set deviation water output m', that is, M'+m'.

[0099] Then, it is determined whether the actual water output m falls within the expected water output range.

[0100] If the actual water output m is less than the lower limit of the expected water output range, or, in response to the actual water output being greater than the upper limit of the expected water output range, the actual water output flow rate is calculated based on the actual water output m and the set time period T, and the reference water output flow rate Q is corrected to the actual water output flow rate;

[0101] If the actual water output m is greater than or equal to the lower limit of the expected water output range, and the actual water output m is less than or equal to the upper limit of the expected water output range, the reference water output flow Q is maintained unchanged.

[0102] S5: Get the next set time period, and repeat steps S3 to S5 until there is no next set time period.

[0103] Step S5 is to determine whether there is a next set time period after correcting the reference water flow rate Q. If yes, steps S3 to S5 are repeated; if not, step S6 is executed.

[0104] When the actual water output m is less than the lower limit of the expected water output range, the actual water output flow is calculated according to the actual water output m and the set time period T, and the reference water output flow Q is corrected to the actual water output flow. In order to make up for the shortage of the actual water output m, the display unit of the water output device is controlled to keep displaying the expected water output for a preset time, such as 0.5s, after the set time period;

[0105] After the preset time, the control display unit updates and displays the water output calculated according to the actual water output flow rate and the corresponding water output time in real time until the water output time reaches the next set time period obtained.

[0106] or,

[0107] When the actual water output m is greater than or equal to the lower limit of the expected water output range, and the actual water output m is less than or equal to the upper limit of the expected water output range, and the reference water output flow rate Q is maintained unchanged, the display unit of the water output control device is updated and displayed in real time based on the water output calculated according to the reference water output flow rate and the corresponding water output time, until the water output time reaches the next set time period obtained.

[0108] or,

[0109] When the actual water output is greater than the upper limit of the expected water output range, the actual water output flow is calculated based on the actual water output and the set time period, and the reference water output flow Q is corrected to the actual water output flow. The display unit of the water output control device is updated and displayed in real time based on the water output calculated based on the actual water output flow and the corresponding water output duration until the water output time reaches the next set time period obtained.

[0110] In one embodiment of the present invention, if the actual water output m is equal to 0, the reference water output flow rate Q is maintained unchanged, and the display unit of the water output device is controlled to update the display of the water output calculated based on the reference water output flow rate Q and the corresponding water output duration in real time.

[0111] S6: Determine the target water outlet duration according to the corrected reference water outlet flow rate Q and the target water outlet volume M.

[0112] As a process for accurately determining the target water outlet time, it includes: obtaining the last set time period T and its corresponding actual water outlet, the target water outlet time = (target water outlet M-actual water outlet corresponding to the last set time period T) / corrected reference water outlet flow Q+the last set time period T, and when the total water outlet time of the water outlet equipment reaches the target water outlet time, the water outlet equipment is controlled to stop discharging water, such as by controlling the water receiving pump of the water outlet equipment to stop discharging water.

[0113] A process for roughly determining the target water outlet time includes: target water outlet time = target water outlet volume / corrected reference water outlet flow rate Q, and when the total water outlet time of the water outlet device reaches the target water outlet time, the water outlet device is controlled to stop discharging water.

[0114] Therefore, the control method of the water outlet equipment of the present invention corrects the reference water outlet flow rate Q at least once, determines the target duration based on the corrected reference water outlet flow rate Q and the target water outlet, and controls the water outlet equipment according to the target duration, thereby improving the water outlet accuracy of the water outlet equipment.

[0115] In order to further improve the accuracy of the water outlet device, the set time period T may include multiple time intervals. At this time, the steps for correcting the reference water outlet flow rate Q are as follows:

[0116] The actual water output corresponding to each time interval is obtained, and the actual water output flow corresponding to each time interval is calculated based on each time interval and the actual water output corresponding to each time interval. The average water output flow is calculated based on each actual water output flow. When the sum of the actual water output corresponding to each time interval is less than the lower limit of the expected water output range, or the sum of the actual water output corresponding to each time interval is greater than the upper limit of the expected water output range, the reference water output flow Q is corrected to the average water output flow.

[0117] In order to further improve the accuracy of water outlet of the water outlet device, after the first set time period T, the first actual water outlet time t11 required for the first set water outlet M11 and the second actual water outlet time t12 required for the second set water outlet M12 are obtained; the first water outlet flow Q1 is calculated according to the first set water outlet M11 and the first actual water outlet time t11, that is, Q1=M11 / t11, and the second water outlet flow Q2 is calculated according to the second set water outlet M12 and the second actual water outlet time t12, that is, Q2=M12 / t12; according to the first water outlet flow Q1 and the second water outlet flow Q2, the water outlet time of the water outlet device continues to be controlled.

[0118] In this embodiment, the water outlet duration of the water outlet device is continuously controlled according to the first water outlet flow rate Q1 and the second water outlet flow rate Q2, including the following two situations:

[0119] In the first case, if the first water outlet flow rate Q1 and the second water outlet flow rate Q2 are equal, the target water outlet time t5 required to reach the target water outlet M is calculated based on the reference water outlet flow rate Q, t5=M / Q, and the water outlet is calculated based on the reference water outlet flow rate Q and the corresponding water outlet time. The control display unit continues to update and display the actual water outlet in real time, and when the total water outlet time of the water outlet equipment reaches the target water outlet time t5, the water outlet equipment is controlled to stop discharging water.
