[0030] This application is described in detail below. Examples of embodiments of this application are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. Furthermore, detailed descriptions of known technologies that are unnecessary for the features of this application are omitted. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0031] It will be understood by those skilled in the art that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0032] Those skilled in the art will understand that, unless otherwise stated, the singular forms “a,” “an,” “the,” and “the” used herein may also include the plural forms. It should be further understood that the word “comprising” as used in this application’s specification means the presence of the stated features, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof.

[0033] This application provides a control method for a water storage container. The water storage container includes a tank and a signal sensor fixed inside the tank. The signal sensor is used to transmit a detection signal to the bottom surface of the tank in a vertical direction.

[0034] In one possible embodiment, the signal sensor is fixed to the upper part of the housing. The signal sensor is an ultrasonic sensor. The ultrasonic sensor includes a signal transmitting part and a signal receiving part.

[0035] Optionally, the box can be a cube.

[0036] Optionally, the box body is a cuboid.

[0037] like Figure 1 As shown, the control method for the water storage container mainly includes steps S1-S4:

[0038] Step S1: Obtain the preset water inlet volume, the pre-stored calibration coefficient, and the first time.

[0039] The first time is the time it takes for the detection signal to reach the bottom of the tank when the tank is empty. The preset water intake volume can be set by the user before adding water.

[0040] Step S2: Determine the second time when the detection signal reaches the target liquid surface based on the calibration coefficient, preset water inflow, and first time.

[0041] The target liquid level is the liquid level when the influent volume reaches the preset influent volume.

[0042] Step S3: Upon receiving the water inlet signal, activate the signal sensor and acquire the third time when the detection signal reaches the current water inlet level.

[0043] After the signal sensor is activated, it emits a detection signal at a preset emission period and acquires the third time when the detection signal reaches the current inlet water surface. Specifically, the signal sensor emits the detection signal vertically towards the current inlet water surface and records the first emission time. After reflection from the current inlet water surface, the detection signal is reflected vertically back to the signal sensor, which receives the reflected signal and records the first reception time. The difference between the first reception time and the first emission time is divided by two to determine the third time.

[0044] Step S4: If the third time is equal to the second time, then stop the water intake.

[0045] In one possible embodiment, the product of the difference between the first time and the third time and the propagation speed of the detection signal is determined as the current water level in the tank; the product of the water level and the bottom area of ​​the tank is determined as the current water volume. If the third time equals the second time, it means that the current water level is equal to the preset water level, i.e., the current water volume has reached the preset water volume, and water intake is stopped at this time to prevent the current water volume from exceeding the preset water volume.

[0046] The control method for the water storage container provided in this application utilizes the fact that the detection signal emitted by the signal sensor will be reflected when it encounters an obstacle. The distance from the detection signal to the current water level is determined by the transmission and reception time of the detection signal, thereby determining whether the current water level has reached the preset water level. If so, it is determined that the current water level has reached the preset water level. This can avoid the problem of the water flow meter being unable to properly obtain the water level due to scale blockage caused by long-term use, thus improving the accuracy of water level control.

[0047] As an optional implementation, step S2 above, determining the second time when the detection signal reaches the target liquid surface based on the calibration coefficient, the preset influent volume, and the first time, includes:

[0048] The absolute value of the difference between the product of the preset influent volume and the calibration coefficient and the first time is determined as the second time.

[0049] In one possible embodiment, the formula for determining the second time when the detection signal reaches the target liquid surface, based on the calibration coefficient, the preset influent volume, and the first time, is as follows:

[0050] t2 = t1 - KV1;

[0051] Where t2 is the second time, t1 is the first time, K is the calibration coefficient, and V1 is the volume of the preset influent.

[0052] As an alternative implementation method, such as Figure 2 As shown, the water storage container also includes an inlet flow meter. During the calibration phase, the control method for the water storage container further includes steps S10-S40:

[0053] Step S10: If there is no water in the tank, activate the signal sensor to determine the first time.

[0054] With all the water drained from the tank, the signal sensor emits a detection signal vertically towards the bottom of the tank and records the second emission time. The detection signal is reflected off the bottom of the tank and then reflected vertically back to the signal sensor. The signal sensor receives the reflected detection signal and records the second reception time. The difference between the second reception time and the second emission time is divided by two to determine the first time.

[0055] Step S20: Upon receiving the water inlet signal, obtain the current water inlet volume through the water inlet flow meter, and stop the water inlet when the current water inlet volume reaches the preset calibration water inlet volume.

[0056] The accuracy of the incoming water can be ensured by using a fault-free inlet flow meter during the calibration stage before the product leaves the factory.

[0057] Step S30: Activate the signal sensor and acquire the fourth time when the detection signal reaches the inlet water level corresponding to the calibrated inlet water volume.

[0058] The method for obtaining the fourth time is similar to the method for obtaining the third time, so it will not be repeated here.

[0059] Step S40: The ratio of the difference between the first time and the fourth time to the calibration influent volume is determined as the calibration coefficient.

[0060] Based on the foregoing embodiments, in one possible embodiment, for ease of explanation, the formula for determining the liquid level height of the preset inlet water in the tank is as follows:

[0061] H1 = v(t1 - t2);

[0062] Where H1 is the preset water level in the tank, v is the speed of the detection signal propagation, t1 is the first time, and t2 is the second time.

[0063] The formula for determining the preset influent volume is:

[0064] V1 = SH1;

[0065] Where V1 is the volume of the preset inlet water, S is the bottom area of ​​the tank, and H1 is the height of the liquid level of the preset inlet water in the tank.

[0066] The formula for determining the liquid level height of the calibration inlet water in the tank is:

[0067] H2 = v(t1 - t4);

[0068] Where H2 is the liquid level height of the calibration inlet water in the tank, v is the propagation speed of the detection signal, t1 is the first time, and t4 is the fourth time.

[0069] The formula for determining the calibration influent volume is:

[0070] V2 = SH2;

[0071] Where V2 is the volume of the calibration inlet water, S is the bottom area of ​​the tank, and H2 is the liquid level height of the calibration inlet water inside the tank.

[0072] Comparing V1 and V2, we get t2 = t1 - (V1(t1-t4) / V2). As we know from the above, K = (t1-t4) / V2.

[0073] Where t2 is the second time, t1 is the first time, V1 is the volume of the preset inlet water, V2 is the volume of the calibration inlet water, and K is the calibration coefficient.

[0074] Since the first time, the fourth time, the volume of the preset water intake, and the volume of the calibrated water intake are all available before water intake, the second time can be determined before water intake.

[0075] As an alternative implementation method, such as Figure 3 As shown, the water storage container also includes an inlet flow meter, and the control method for the water storage container further includes steps S50-S60:

[0076] Step S50: Obtain the target number of pulses corresponding to the inlet flow meter when the preset inlet water flow into the tank; when the inlet water signal is received, control the inlet flow meter to start pulse counting.

[0077] The target pulse count can be obtained from the product manual of the inlet flow meter. If the inlet flow rate corresponding to the target pulse count in the product manual is not equal to the aforementioned preset inlet flow rate, then the inlet flow rate corresponding to the target pulse count will flow into the tank. This application embodiment uses the inlet flow rate corresponding to the target pulse count as the preset inlet flow rate as an example for illustration.

[0078] Step S60: When the number of pulses of the inlet flow meter reaches the target number of pulses, if the third time is not equal to the second time, then output the inlet flow meter fault signal.

[0079] When the inlet flow meter is working normally, the third time is equal to the second time when the number of pulses of the inlet flow meter reaches the target number of pulses; if the third time is not equal to the second time when the number of pulses of the inlet flow meter reaches the target number of pulses, it indicates that the inlet flow meter is faulty.

[0080] As an alternative implementation method, such as Figure 4 As shown, the water storage container also includes an inlet flow meter, and the control method for the water storage container further includes steps S70-S90:

[0081] Step S70: Obtain the target number of pulses corresponding to the inlet flow meter when the preset inlet water volume flows into the tank.

[0082] Step S80: Upon receiving the water inlet signal, control the water inlet flow meter to start pulse counting.

[0083] Step S90: When the third time is equal to the second time, if the number of pulses of the inlet flow meter is not equal to the target number of pulses, then output the inlet flow meter fault signal.

[0084] When the inlet flow meter is working normally, when the third time equals the second time, the number of pulses of the inlet flow meter is equal to the target number of pulses; when the third time equals the second time, if the number of pulses of the inlet flow meter is not equal to the target number of pulses, it indicates that the inlet flow meter is faulty.

[0085] To prevent overflow, pressure switches are typically used. When the water level reaches a high level, the pressure switch is triggered to drain the water. However, pressure switches have a relatively large accuracy error, which can lead to false triggering or failure to reset after a pressure change. When the inlet valve ages or malfunctions, leakage can occur, causing water to continuously enter and eventually overflow.

[0086] As an alternative implementation method, such as Figure 5As shown, the control method for the water storage container also includes steps S100-S200:

[0087] Step S100: Obtain the pre-stored fifth time. The fifth time is the time it takes for the detection signal to reach the inlet water level corresponding to the preset warning inlet water volume.

[0088] During the calibration phase, the fifth time can be obtained. The method for obtaining the fifth time is similar to the methods for obtaining the fourth and third times, so it will not be described again here.

[0089] Step S200: During the water intake process, if the time it takes for the acquired detection signal to reach the current water level is equal to the fifth time, then drainage is started.

[0090] When the detection signal reaches the current inlet water level at time five, it indicates that the inlet water volume has reached the warning level, and drainage is initiated to prevent water overflow. Compared to the drainage method using a pressure switch, this drainage method is not limited by air pressure and is more flexible in terms of operating environment.

[0091] It should be understood that, although Figure 1-5 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise explicitly stated in this document, there is no strict order in which these steps are executed; they can be performed in other orders. Furthermore, Figure 1-5 At least some of the steps in the process may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but may be executed at different times. The execution order of these steps or stages is not necessarily sequential, but may be executed in turn or alternately with other steps or at least some of the steps or stages in other steps.
