[0001] The present invention relates to the technical fields of data processing and water supply device control, and particularly to a control method, device, water supply device and storage medium for a water supply device. Background Art

[0002] In the field of hot water supply of traditional water supply devices, due to the limited accuracy of water level sensors, there is often a lack of accurate water level detection and control mechanisms, making it difficult to accurately feedback real-time water level information. Moreover, the setting of water replenishment parameters lacks scientificity and flexibility. Only based on simple water level difference calculations, factors such as the non-linear relationship between water level and water volume caused by the irregular shape of the water supply device are ignored, resulting in inaccurate water level control during the water replenishment process. Therefore, how to achieve more accurate water level control has become an urgent problem to be solved at present. Summary of the Invention

[0036] The water supply device 1 provided by this application can effectively transfer the heat generated by the host to the water that needs to be heated through the heat exchange module 21, can transfer heat efficiently, uses a large contact area and a reasonable structure to accelerate heat exchange, improves the heating efficiency, and can accurately control the water temperature.

[0037] Among them, the water supply device and the water supply device can be named in different scenarios, which does not limit this application. The heat storage and heating module 22 can be a heat tank or a square tank, and this application does not limit this. Exemplarily, such asFigure 1C and Figure 1D as shown Figure 1C and Figure 1D shows a schematic structural view of a square tank body 303. A square tank body (303) for storing a heat exchange medium, the square tank body (303) includes an inner shell (3011), a top plate (3033) and a bottom plate (3022), the top plate (3033) is fixed to the top of the inner shell (3011), and the bottom plate (3022) is fixed to the bottom of the inner shell (3011).

[0038] The square tank body is composed of an inner shell, a top plate and a bottom plate. The inner shell is integrally formed with high structural strength. Compared with the traditional cylindrical heat tank, the square inner shell has a larger water capacity. After the inner shell is manufactured, the top plate is welded to the top of the inner shell, and then the bottom plate is welded to the bottom of the inner shell to form the square tank body. The heat preservation frame plate can be used to heat-preserve the outside of the square tank body. The heat preservation frame plate is composed of three layers of heat preservation materials, and the heat preservation performance of the square tank body can be improved through the three layers of heat preservation materials. An outer shell is sleeved outside the inner shell of the square tank. A plurality of reinforcing plates are fixedly welded on the inner wall of the outer shell. The reinforcing plates can improve the structural strength between the outer shell and the inner shell. A cavity is formed between the inner shell and the outer shell, and an inert gas can be filled into the cavity, and in this way, the heat preservation performance and structural strength of the square tank body can be enhanced.

[0039] Please refer to Figure 2 as shown Figure 2 which is a schematic flowchart of a control method for a water supply device provided by an embodiment of the present invention, including the following steps:

[0040] S1: Obtain a water level control signal, and the water level control signal includes target water level information.

[0041] Among them, the water level control signal can be an instruction for indicating the water level information to which the water level inside the water supply device (such as inside the square tank for storing the heat exchange medium in the water supply device) should be adjusted. Hereinafter, taking the water level control of the square tank of the water supply device as an example for illustration, which does not limit the present application.

[0042] It is understandable that the water level control signal may include target water level information, that is, the height of the water level expected to be reached inside the water supply device. It is understandable that the water supply device may have a mechanism, such as the feedback mechanism of the above water level control signal, to more precisely control the water level inside the water supply device.

[0043] S2: In response to the water level control signal, obtain the current water level information and make-up water parameter information in the square tank for storing the heat exchange medium in the water supply device through a water level sensor.

[0044] Among them, the current water level information can be used to indicate the current water level of the heat tank detected by the water level sensor. This current water level information can reflect the current actual water level height in the heat tank. The make-up water parameter information can be used to indicate various relevant data when making up water to the water supply device, for example, it can include but is not limited to the flow rate limit of the incoming water, the range of the incoming water pressure, the maximum opening of the make-up water valve, etc.

[0045] When the water supply device receives the water level control signal, it can respond to the water level control signal and can initiate relevant operations to obtain the current water level information and make-up water parameter information in the square tank. It is understandable that by obtaining the current water level information and make-up water parameter information, it is beneficial to more accurately control the water level in subsequent steps.

[0046] S3: Determine water level control information according to the target water level information, the current water level information, and the make-up water parameter information.

[0047] Among them, the water level control information can be a set of instructions for controlling the water level of the water supply device determined after comprehensively considering the target water level information, the current water level information, and the make-up water parameter information. The water level control information can include but is not limited to specific operation information such as flow rate control of make-up water (or drainage), valve opening control, make-up water (or drainage) time control, etc.

[0048] In a possible implementation manner, the process of determining the water level control information according to the target water level information, the current water level information, and the make-up water parameter information may include the following steps;

[0049] A1: Determine the amount of water to be replenished according to the target water level information and the current water level information;

[0050] A2: Determine the water level control information according to the amount of water to be replenished and the make-up water parameter information.

[0051] Among them, the water replenishment amount to be supplemented can be the amount of water that needs to be supplemented calculated through the difference between the target water level and the current water level (i.e., the water level difference). The calculation method of the water replenishment amount to be supplemented can vary according to the representation of the water level, and this application does not limit it. It can be understood that when determining the water replenishment amount to be supplemented based on the target water level information and the current water level information, the inclination angle of the square tank relative to the horizontal plane may also need to be considered. For the same water level difference, if the inclination angle of the square tank relative to the horizontal plane is different, the corresponding water replenishment amount can also be different. Specifically, the specific water replenishment amount to be supplemented can be obtained through calculation based on the inclination angle of the square tank relative to the horizontal plane, the water level difference, the size parameters of the water-containing space inside the square tank, etc., and this application does not limit it.

[0052] The water level control information can be further determined according to the water replenishment amount to be supplemented and the water replenishment parameter information. For example, if the water replenishment amount to be supplemented is large and the maximum water inlet flow rate in the water replenishment parameters allows, a relatively high initial water replenishment flow rate can be determined; at the same time, the maximum opening degree and opening degree adjustment accuracy of the water replenishment valve can also be considered to adjust the valve to achieve the set water replenishment flow rate. Optionally, according to the water replenishment amount to be supplemented and the water replenishment parameter information, a look-up table method can be used to determine the water level control information, and this application does not limit it.

[0053] In a possible implementation manner, the process of determining the water level control information according to the water replenishment amount to be supplemented and the water replenishment parameter information may include the following steps;

[0054] B1: Determine the water replenishment flow rate control information according to the water replenishment amount to be supplemented;

[0055] B2: Determine the water level control information according to the water replenishment flow rate control information and the water replenishment parameter information.

[0056] Among them, the water replenishment flow rate control information can be information related to how to control the water flow rate during the water replenishment process. Optionally, a strategy of first replenishing water at a large flow rate and then at a small flow rate can be adopted. That is to say, the water replenishment flow rate control information can determine the flow rate magnitude at different stages and the timing of the flow rate change. For example, for a relatively large water replenishment amount to be supplemented, the water replenishment flow rate may be initially set at 3 liters per minute for rapid water replenishment, and when the water level is close to the target water level, the flow rate is reduced to 1 liter per minute for fine water replenishment.

[0057] After determining the water replenishment flow rate control information, the water level control information can be further determined by combining the water replenishment flow rate control information and the water replenishment parameter information.

[0058] In a possible implementation manner, the process of determining the water replenishment flow rate control information according to the water replenishment amount to be supplemented may include the following steps;

[0059] C1: Determine the initial water replenishment flow rate curve according to the water replenishment amount to be supplemented;

[0060] C2: Segment the initial makeup water flow rate curve and the preset makeup water volume to obtain a first sub-initial makeup water flow rate curve and a second sub-initial makeup water flow rate curve;

[0061] C3: Obtain the reference makeup water volume corresponding to the second sub-initial makeup water flow rate curve;

[0062] C4: Construct a sub-makeup water flow rate curve based on the reference makeup water volume to obtain a third sub-initial makeup water flow rate curve;

[0063] C5: Integrate the first sub-initial makeup water flow rate curve and the third sub-initial makeup water flow rate curve to obtain a target makeup water flow rate curve;

[0064] C6: Determine the makeup water flow rate control information according to the target makeup water flow rate curve.

[0065] Among them, the initial makeup water flow rate curve can be a curve used to describe the variation of the flow rate with time during the makeup water process, which is preliminarily determined according to the makeup water volume to be supplemented. This initial makeup water flow rate curve can be constructed based on the makeup water volume to be supplemented and possible makeup water strategies. For example, at the beginning of makeup water, a higher flow rate can be set due to a large water volume gap. As the makeup water process progresses, the flow rate can gradually decrease or change according to a certain rule. For example, the initial flow rate can be 5 liters per minute, and then it can change at a rate of decreasing 0.1 liter per minute per minute, etc.

[0066] The preset makeup water volume can be a reference quantity set artificially and related to the makeup water volume to be supplemented. Exemplarily, assume that the preset makeup water volume is set to 70% of the makeup water volume to be supplemented; if the makeup water volume to be supplemented is 200 liters, then the preset makeup water volume can be 140 liters.

[0067] The first sub-initial makeup water flow rate curve can be the part of the flow rate curve corresponding to a part of the makeup water stage (i.e., the makeup water stage with a larger flow rate in the early stage) after segmenting the initial makeup water flow rate curve according to the preset makeup water volume. This first sub-initial makeup water flow rate curve can describe the variation rule of the makeup water flow rate in the makeup water stage with a larger flow rate in the early stage.

[0068] The second sub-initial makeup water flow rate curve can be the part of the flow rate curve after the preset makeup water volume corresponding to the segmented part, which is mainly used to describe the variation rule of the makeup water flow rate in the transition to a more refined makeup water stage in the later stage.

[0069] The reference makeup water volume can be the amount of water that needs to be supplemented corresponding to the second sub-initial makeup water flow rate curve, that is, the remaining part of the makeup water volume to be supplemented after exceeding the preset makeup water volume. Exemplarily, if the makeup water volume to be supplemented is 200 liters and the preset makeup water volume is set to 70% of the makeup water volume to be supplemented, then the reference makeup water volume is 200 - 140 = 60 liters.

[0070] The third sub-initial makeup water flow rate curve can be a flow rate curve constructed based on the reference makeup water volume for more precise control of the later makeup water. During the process of later makeup water, more refined flow rate changes are usually considered. For example, the rate of decrease in the flow rate is smaller or a more complex flow rate control strategy is adopted to ensure accuracy when approaching the target water level.

[0071] The target makeup water flow rate curve can be the final makeup water flow rate curve obtained by fusing the first sub-initial makeup water flow rate curve and the third sub-initial makeup water flow rate curve. The target makeup water flow rate curve can completely describe the law of flow rate change during the entire makeup water process, that is, from the start to the end of the makeup water process, and can be used to precisely control the makeup water operation.

[0072] According to the above target makeup water flow rate curve, the specific makeup water flow rate values and flow rate change information, that is, the makeup water flow rate control information, that should be adopted at different times during the makeup water process can be determined, so as to directly control the makeup water equipment (such as water pumps, valves, etc.) to adjust the water flow rate.

[0073] In a possible implementation manner, the process of constructing the third sub-initial makeup water flow rate curve by constructing the sub-makeup water flow rate curve according to the reference makeup water volume may include the following steps;

[0074] D1: Perform an equal division process on the reference makeup water volume to obtain k sub-reference makeup water volumes;

[0075] D2: Sort the k sub-reference makeup water volumes according to the makeup water time sequence to obtain a makeup water sequence;

[0076] D3: Determine the makeup water flow rate corresponding to each sub-reference makeup water volume in the makeup water sequence to obtain a makeup water flow rate sequence, and the makeup water flow rate sequence is a decreasing flow rate sequence;

[0077] D4: Construct a reference makeup water curve according to the makeup water flow rate sequence;

[0078] D5: Smooth the reference makeup water curve to obtain the third sub-initial makeup water flow rate curve.

[0079] In order to more precisely control the flow rate change in the later stage of makeup water, the reference makeup water volume is equally divided to obtain multiple equal portions of water volume, that is, the above k sub-reference makeup water volumes. Here, k can represent the number of equal division portions, and the value of k can be set according to the actual control accuracy requirements. These k sub-reference makeup water volumes can be understood as the corresponding water volume units for determining the makeup water flow rate in different stages later.

[0080] After arranging the k sub-reference water replenishment amounts according to the water replenishment time sequence (i.e., the order of water replenishment), the formed sequence is the water replenishment sequence. During the subsequent water replenishment process, each sub-reference water replenishment amount can be replenished in sequence according to the order of the water replenishment sequence.

[0081] Water replenishment flow rate sequence (flow rate decreasing sequence):

[0082] For each sub-reference water replenishment amount in the water replenishment sequence, the corresponding water replenishment flow rate can be further determined, thereby further forming a water replenishment flow rate sequence. This water replenishment flow rate sequence is a flow rate decreasing sequence, that is, the flow rate in this sequence gradually decreases. Considering that as the water level gets closer and closer to the target water level, in order to more accurately control the water level, the water replenishment flow rate needs to gradually slow down.

[0083] Furthermore, taking the sub-reference water replenishment amount in the water replenishment sequence as the abscissa and the corresponding water replenishment flow rate sequence as the ordinate, connecting each corresponding data point can form a reference water replenishment curve. This reference water replenishment curve is constructed based on discrete sub-reference water replenishment amounts and corresponding water replenishment flow rates, so it is a discrete curve and can be used to intuitively present the water replenishment flow rate conditions corresponding to different water replenishment amount stages.

[0084] After smoothing the reference water replenishment curve, the third sub-initial water replenishment flow rate curve can be obtained. It can be understood that this third sub-initial water replenishment flow rate curve still follows the law of decreasing flow rate in each interval. Compared with the discrete reference water replenishment curve, the third sub-initial water replenishment flow rate curve is more continuous and smoother, and can be better used for actual water replenishment control operations. It can be an important part finally used to construct the target water replenishment flow rate curve and can be used to describe the more accurate and smoother change of the water replenishment flow rate in the later stage of water replenishment.

[0085] In one possible implementation manner, the process of determining the water level control information according to the target water level information, the current water level information, and the water replenishment parameter information may include the following steps;

[0086] E1: Determine the water replenishment amount to be replenished according to the target water level information and the current water level information;

[0087] E2: Determine the first water replenishment flow rate from the water replenishment flow rate table according to the water replenishment amount to be replenished and the water replenishment parameter information;

[0088] E3: Determine the water level control information according to the first water replenishment flow rate.

[0089] Among them, the make-up water flow rate table can be a pre-set data table, which can record the appropriate make-up water flow rates corresponding to different amounts of water to be replenished, make-up water parameters, etc. The make-up water flow rate table can be formulated according to factors such as the characteristics of the water supply device and the performance of the make-up water system, and can be used for quickly querying and determining the appropriate make-up water flow rate.

[0090] The first make-up water flow rate can be used to indicate the initial make-up water flow rate queried from the make-up water flow rate table based on the information of the amount of water to be replenished and the make-up water parameters. The first make-up water flow rate can be determined by considering factors such as the size of the amount of water to be replenished and the capacity of the make-up water system, and can be an important part of the water level control information. The make-up water operation can start with the first make-up water flow rate.

[0091] S4: Perform water level control on the water supply device according to the water level control information.

[0092] It can be understood that the water level control information can be directly used to operate the relevant components of the water supply device (such as the inlet valve, drain valve, water pump, etc.), and the relevant components can perform corresponding operations according to the water level control information to achieve precise control of the water level of the water supply device, so as to further make it reach the target water level.

[0093] Exemplarily, if the water level control information indicates that water needs to be inlet at a certain flow rate and the make-up water operation needs to be completed within a certain time, the control module of the water supply device can open the inlet valve according to the indication of the water level control information and let water enter the water supply device at the required flow rate until the target water level is reached, so as to achieve precise control of the water level of the water supply device.

[0094] In the embodiment of the present application, by obtaining a water level control signal including target water level information and responding to the water level control signal, the current water level information and make-up water parameter information in the square tank for storing the heat exchange medium in the water supply device can be obtained through a water level sensor.
