[0051] It should be noted that, since the hot water and the hot water path have relatively low requirements on the flow rate, in order to save space and material cost while meeting the functions, the hot water and the hot water path can use pipes with relatively small diameters, such as 2-inch pipes.

[0055] Please refer to Figure 2 , Figure 2 A flowchart of a cleaning method of a water supply device is provided for the embodiments of the present application. The method is used for cleaning the water supply device, which includes a water inlet module, a heating module and a water outlet module, and includes the following steps:

[0056] S1, a water path cleaning trigger signal is obtained, which is used to indicate that water path cleaning is performed.

[0057] In the embodiments of the present application, the water supply device can include a control module, and the signal type of the water path cleaning trigger signal can be one of the following: a digital signal, a pulse signal, a software instruction signal, etc., which is not limited herein.

[0058] In specific embodiments, when it is detected that the water supply device needs to be cleaned, the waterway cleaning trigger signal can be generated by the control module. Specifically, water quality sensors can be installed at the water inlet and the water outlet of the water supply device to detect water quality parameters such as hardness (calcium and magnesium ion concentration), pH value, and conductivity. The water quality parameters at the water inlet and the water outlet are obtained, the difference between the water quality parameters at the water inlet and the water outlet is calculated to obtain a first difference, and when the first difference is greater than a preset difference, it is determined that the internal environment of the water supply device contains impurities or dirt and needs to be cleaned. The corresponding trigger signal can be generated according to the first difference to obtain the waterway cleaning trigger signal. For example, assuming that the water quality parameter is water hardness, the difference between the water hardness at the water inlet and the water hardness at the water outlet (hardness difference = water hardness at the water inlet - water hardness at the water outlet) is calculated. The hardness difference threshold is set to 50 mg / L, and when the hardness difference is greater than 50 mg / L (this value can be adjusted according to the actual situation and experience of the water supply device), it indicates that a considerable amount of scale has been formed inside the water supply device and needs to be cleaned. This is because a larger hardness difference means that more calcium and magnesium ions have precipitated inside the water supply device, affecting the water quality and the performance of the water supply device. Then, the waterway cleaning trigger signal is generated based on the hardness difference, or the user can manually start the cleaning function of the water supply device to generate the waterway cleaning trigger signal.

[0059] Optionally, the water inlet module is connected to the heating module and the water outlet module, specifically, electrically connected, and the heating module is connected to the water outlet module, also electrically connected.

[0060] S2, in response to the waterway cleaning trigger signal, obtaining the state information of the water supply device.

[0061] In embodiments of the present application, the state information of the water supply device can include at least one of the following: the health status of the water supply device, the liner state of the water supply device (which can be understood as the degree of scale adhesion of the liner of the water supply device), the degree of scale adhesion of the water supply device, the state of the water inlet module, the state of the water outlet module, and the like, which are not limited herein.

[0062] In specific embodiments, in response to the waterway cleaning trigger signal, the water supply device is subjected to state detection to obtain state information. Specifically, the state information can include the health status of the water supply device and the scale adhesion degree of the water supply device. An electrical detection module can be provided on the water supply device, and the electrical parts of the water supply device, such as the heating module and the control module, are subjected to self-detection at regular intervals (e.g., once a week). For example, the resistance value of the heating tube in the heating module is detected to determine whether it is working normally. Under normal circumstances, the heating tube has a standard resistance range. When the resistance value is detected to be out of this range, it indicates that the heating tube has a fault, such as a local short circuit or open circuit. At the same time, the key electronic components (such as capacitors and chips) on the control module are subjected to voltage and current monitoring to check whether there is an abnormal voltage fluctuation or current overload, thereby obtaining the health status of the water supply device. Then, the scale adhesion degree of the water supply device can also be detected. For example, the water quality parameter comparison method can be used to determine the scale adhesion degree according to the above hardness difference. A preset mapping relationship between the preset hardness difference and the scale adhesion degree can be set in advance, and the scale adhesion degree corresponding to the hardness difference between the water outlet and the water inlet can be determined according to the mapping relationship. Alternatively, the physical detection method can be used. An ultrasonic sensor can be installed in the water supply device to detect the thickness of the scale by using the ultrasonic reflection principle. When the ultrasonic sensor emits an ultrasonic pulse, a reflected wave is generated when the ultrasonic pulse encounters the interface between the scale and the inner container wall of the water supply device. According to the time and intensity of the reflected wave, the thickness of the scale can be calculated. For example, the propagation speed of ultrasonic waves in water is known, and the distance from the sensor to the interface between the scale and the inner container wall can be accurately calculated by measuring the time delay of the reflected wave, thereby obtaining the thickness of the scale, i.e., the scale adhesion degree of the water supply device.

[0063] S3, determining target cleaning control information of the ultrasonic cleaning device according to the state information.

[0064] In the embodiments of the present application, the water supply device can be analyzed according to the state information, so as to determine the target cleaning control information of the ultrasonic cleaning device.

[0065] Optionally, step S3, the target cleaning control information of the ultrasonic cleaning device is determined according to the state information, including:

[0066] A1, extracting impurity deposition information of a heating energy storage module in the heating module from the state information;

[0067] A2, determining the target cleaning control information according to the impurity deposition information.

[0068] In the embodiments of the present application, the impurity deposition information can include at least one of the following: impurity type, impurity thickness, impurity deposition position, impurity deposition amount, etc.

[0069] In specific embodiments, the state information can include the scale adhesion degree of the water supply device, the impurity deposition information of the heating energy storage module can be determined according to the scale adhesion degree of the water supply device, and specifically, the impurity deposition information can include the impurity type. If the scale adhesion degree is high, it can be inferred that the proportion of calcium-magnesium compounds (such as calcium carbonate and magnesium hydroxide) in the impurity deposition is large according to the water quality. For example, when the water hardness is mainly composed of calcium hardness, and the scale adhesion speed is fast, it can be inferred that the main component of the deposition is calcium carbonate. The specific proportion of calcium-magnesium compounds can be further determined by chemical analysis (such as chemical titration on a small amount of collected scale sample); then, the target cleaning control information can be determined according to the impurity deposition information.

[0070] In this way, by specially extracting the impurity deposition information of the heating energy storage module in the heating module from the state information, the key area of cleaning can be focused. Because the heating energy storage module is one of the core parts of the water supply device, its performance directly affects the efficiency and quality of hot water production. For example, in a storage water supply device, the impurity deposition (such as scale) around the heating pipe can seriously hinder heat transfer, making the heating time longer and the energy consumption increased. Precise extraction of this part of information is like providing a precise "map" for cleaning work, which can make the cleaning control information more targeted to the area most in need of cleaning, thereby improving the cleaning efficiency.

[0071] Optionally, in step A2, the target cleaning control information is determined according to the impurity deposition information, comprising:

[0072] B1, extracting first impurity distribution information of the bottom of the heating energy storage module and second impurity distribution information of the inner wall of the heating energy storage module from the impurity deposition information;

[0073] B2, determining first initial cleaning control information according to the first impurity distribution information and the second impurity distribution information;

[0074] B3, extracting first impurity deposition thickness of the bottom of the heating energy storage module and second impurity deposition thickness of the inner wall of the heating energy storage module from the impurity deposition information;

[0075] B4, determining second initial cleaning control information according to the first impurity deposition thickness and the second impurity deposition thickness;

[0076] B5, fusing the first initial cleaning control information and the second initial cleaning control information to obtain the target cleaning control information.

[0077] In the embodiments of the present application, the impurity deposition thickness can be the average thickness, for example, the average thickness of scale.

[0078] In specific embodiments, target impurity distribution information of the heating energy storage module can be extracted from the impurity deposition information, and then the target impurity distribution information is divided into first impurity distribution information of the bottom of the heating energy storage module and second impurity distribution information of the inner wall of the heating energy storage module according to different positions of the impurity attachment. Then, the first initial cleaning control information can be determined according to the first impurity distribution information and the second impurity distribution information.

[0079] Further, target impurity deposition thickness information of the heating energy storage module can be extracted from the impurity deposition information, and then the target impurity deposition thickness information is divided into first impurity deposition thickness of the bottom of the heating energy storage module and second impurity deposition thickness of the inner wall of the heating energy storage module according to different positions of the impurity attachment. Then, the second initial cleaning control information can be determined according to the first impurity deposition thickness and the second impurity deposition thickness. Finally, the first initial cleaning control information and the second initial cleaning control information can be fused to obtain target cleaning control information. Specifically, different fusion modes can be performed according to the cleaning parameters controlled by the first initial cleaning control information and the second initial cleaning control information, for example, assuming that the cleaning parameters controlled by the first initial cleaning control information and the second initial cleaning control information are the same, both of which control the ultrasonic wave emission frequency of the ultrasonic cleaning device, then the effects of the position and thickness of the impurity on the ultrasonic wave emission frequency can be considered respectively. If the position of the impurity is more concentrated, then a higher ultrasonic wave emission frequency is more effective in this case, because the energy of the high-frequency ultrasonic wave is concentrated in a smaller area, which can more accurately act on the impurities on the inner wall, so that they are subjected to enough energy impact and fall off locally. Therefore, a higher weight 0.7 can be assigned to the first initial cleaning control information, and a lower weight 0.3 can be assigned to the second initial cleaning control information. Based on the two weights, the first initial cleaning control information and the second initial cleaning control information are fused to obtain the final target cleaning control information. For another example, assuming that the cleaning parameters controlled by the first initial cleaning control information and the second initial cleaning control information are different, the first initial cleaning control information controls the ultrasonic wave emission direction of the ultrasonic cleaning device, and the second initial cleaning control information controls the ultrasonic wave emission frequency of the ultrasonic cleaning device. Then, the first initial cleaning control information and the second initial cleaning control information can be directly superimposed to obtain the target cleaning control information, for example, the target cleaning control information can be that the ultrasonic cleaning device emits ultrasonic waves with the emission frequency corresponding to the second initial cleaning control information in the emission direction corresponding to the first initial cleaning control information.

[0080] Thus, by determining the first initial cleaning control information according to the distribution information, the angle of the ultrasonic cleaning device can be adjusted, the cleaning time can be increased, or the cleaning intensity of a local area can be increased according to the characteristics of the impurity distribution, such as the area where the impurities are concentrated. In this way, indiscriminate cleaning of the entire heating energy storage module can be avoided, thereby improving the cleaning efficiency and reducing unnecessary energy consumption.

[0081] Optionally, in step B2, the first initial cleaning control information is determined according to the first impurity distribution information and the second impurity distribution information, and the step includes:

[0082] C1, the first impurity distribution information is used to mark a key cleaning area to obtain a first key cleaning area;

[0083] C2, the second impurity distribution information is used to mark a key cleaning area to obtain a second key cleaning area;

[0084] C3, according to the first area position information of the first key cleaning area, the second area position information of the second key cleaning area, and the position information of the ultrasonic cleaning device, the ultrasonic emission direction information of the ultrasonic cleaning device is determined;

[0085] C4, the ultrasonic emission direction information is determined as the first initial cleaning control information.

[0086] In the embodiment of the present application, the first impurity distribution information is used to mark a key cleaning area to obtain a first key cleaning area. Specifically, the first impurity distribution information can be visually processed. If the first impurity distribution information is an impurity distribution image obtained by ultrasonic detection or optical detection, professional software can be used to convert these data into intuitive graphics. For example, the bottom of the heating energy storage module is taken as a plane, and the impurity distribution is represented on the graphics with different color depths. The deeper the color, the more impurities there are in the area. In this way, the overall distribution of impurities on the bottom can be clearly seen. A threshold value of impurity area (for example, 3 square millimeters) is set to determine the key cleaning area. For example, if it is found through analysis that the area with an impurity area of more than 3 square millimeters has a greater impact on the performance of the heating energy storage module, all areas with an impurity area of more than 3 square millimeters are marked as key cleaning areas in the visual graphics. This threshold value can be determined according to the specific performance parameters of the water supply device, the material of the heating energy storage module, and the past cleaning experience, etc. Then, the second impurity distribution information can also be used to mark a key cleaning area to obtain a second key cleaning area. Specifically, the method of obtaining the second key cleaning area can be the same as the method of obtaining the first key cleaning area, which is not limited here.

[0087] Further, the position information of the first key cleaning area in the heating and energy storage module can be acquired to obtain first area position information, the position information of the second key cleaning area in the heating and energy storage module can be acquired to obtain second area position information, and the position information of the ultrasonic cleaning device can be acquired. The ultrasonic emission direction information of the ultrasonic cleaning device can be determined according to the first area position information, the second area position information and the position information of the ultrasonic cleaning device. Specifically, the center of the heating and energy storage module can be selected as the coordinate origin, a three-dimensional coordinate system can be established according to the geometric shape (for example, a cylindrical coordinate system can be used for a cylindrical body, and a rectangular coordinate system can be used for a cuboid), and the first area position information, the second area position information and the position information of the ultrasonic cleaning device can be represented by the position coordinates of the center position to obtain first position coordinates, second position coordinates and device coordinates. The position vector from the ultrasonic cleaning device to the first key cleaning area can be calculated according to the device coordinates and the first position coordinates to obtain a first position vector. For example, if the center coordinates of the first key cleaning area are (x1, y1, z1) and the coordinates of the ultrasonic cleaning device are (x0, y0, z0), the position vector pointing to the first key cleaning area is (x1-x0, y1-y0, z1-z0). The first position vector is normalized to obtain a unit vector to determine the accurate direction and obtain the first direction from the ultrasonic cleaning device to the first key cleaning area. The normalized vector only represents the direction, and the length of the vector is 1. Similarly, the method for obtaining the second direction from the ultrasonic cleaning device to the second key cleaning area can be the same as the method for obtaining the first direction. Then, the ultrasonic emission direction information can be determined according to the first direction and the second direction and the emission characteristics of the ultrasonic cleaning device. For example, if the emission head of the ultrasonic cleaning device can adjust the angle, the emission direction information can be a set of angle values. For example, in a rectangular coordinate system, the emission direction can be represented by the elevation angle and the azimuth angle. The elevation angle is the angle between the emission direction and the horizontal plane, and the azimuth angle is the angle between the emission direction on the horizontal plane and a reference direction (such as the positive direction of the x-axis). The ultrasonic emission direction information is determined as the first initial cleaning control information.

[0088] In this way, the first key cleaning area and the second key cleaning area are marked by the first impurity distribution information and the second impurity distribution information respectively, and the cleaning resources (such as ultrasonic energy, cleaning time, etc.) can be accurately concentrated in the key area with more impurities and greater impact on the performance of the equipment. This accurate positioning avoids indiscriminate cleaning of the entire heating and energy storage module, and reduces energy waste and time consumption in the cleaning process.

[0089] Optionally, in step B4, the second initial cleaning control information is determined according to the first impurity deposition thickness and the second impurity deposition thickness, including:

[0090] D1, determining a first reference ultrasonic emission frequency of the ultrasonic cleaning device according to the first impurity deposition thickness;

[0091] D2, determining a second reference ultrasonic emission frequency of the ultrasonic cleaning device according to the second impurity deposition thickness;

[0092] D3, determining a fusion factor according to a ratio of the first impurity deposition thickness and the second impurity deposition thickness;

[0093] D4, performing fusion processing on the first reference ultrasonic emission frequency and the second reference ultrasonic emission frequency according to the fusion factor to obtain a target ultrasonic emission frequency;

[0094] D5, determining the target ultrasonic emission frequency as the second initial cleaning control information.

[0095] In the embodiment, the first reference ultrasonic emission frequency can be determined according to the first impurity deposition thickness, for example, a mapping relationship between a preset impurity deposition thickness and a reference ultrasonic emission frequency can be preset, and the first reference ultrasonic emission frequency corresponding to the first impurity deposition thickness can be determined according to the mapping relationship; then, the second reference ultrasonic emission frequency of the ultrasonic cleaning device can be determined according to the second impurity deposition thickness, and the second reference ultrasonic emission frequency corresponding to the second impurity deposition thickness can also be determined according to the mapping relationship; then, the thickness ratio can be obtained by dividing the first impurity deposition thickness by the second impurity deposition thickness, the fusion factor can be determined according to the thickness ratio, for example, a mapping relationship between a preset ratio and a fusion factor can be preset, and the fusion factor corresponding to the thickness ratio can be determined according to the mapping relationship, and the value range of the fusion factor can be 0-1; then, the fusion processing can be performed on the first reference ultrasonic emission frequency and the second reference ultrasonic emission frequency according to the fusion factor, and the specific process is as follows:

[0096] Target ultrasonic emission frequency = first reference ultrasonic emission frequency * fusion factor + second reference ultrasonic emission frequency * (1-fusion factor);

[0097] The target ultrasonic emission frequency can be obtained according to the above formula; finally, the target ultrasonic emission frequency can be determined as the second initial cleaning control information.

[0098] In the cleaning process of the water supply device, the cleaning requirements of the bottom and the inner wall of the heating energy storage module are different but related. The fusion processing on the first reference ultrasonic emission frequency and the second reference ultrasonic emission frequency by the fusion factor can obtain a target ultrasonic emission frequency that takes into account the cleaning of the bottom and the inner wall. This balance can ensure that the energy of the ultrasonic wave can effectively deal with the impurities on the bottom and can also have enough cleaning effect on the impurities on the inner wall.

[0099] Optionally, the method further comprises:

[0100] E1, determining cleaning energy consumption information according to target cleaning control information;

[0101] E2, obtaining an energy consumption fee table;

[0102] E3, determining a cleaning time period when cleaning the water supply device according to the energy consumption fee table and the cleaning energy consumption information.

[0103] In the embodiment of the application, the cleaning energy consumption information is determined according to the target cleaning control information. Specifically, the working power of the ultrasonic cleaning device is obtained, and the unit energy consumption of the ultrasonic cleaning device working at the target ultrasonic emission frequency is calculated according to the working power to obtain the cleaning energy consumption information. Then, the energy consumption fee table can be obtained. Specifically, the region where the water supply device is located and the target energy type used by the water supply device can be obtained first, and then the price table of the target energy type in different time periods in the region, i.e., the energy consumption fee table, can be obtained. For example, assuming that the target energy type is electric energy, the time-of-use electricity price in the region can be obtained to obtain the energy consumption fee table. Then, the cleaning time period can be determined according to the energy consumption fee table and the cleaning energy consumption information. Specifically, the energy prices in different time periods can be determined by checking the energy consumption fee table, and the energy consumption fees in each time period can be calculated according to the cleaning energy consumption information and the energy prices to obtain a plurality of energy consumption fees. The time period corresponding to the smallest energy consumption fee in the plurality of energy consumption fees is selected as the cleaning time period.

[0104] In this way, the cleaning energy consumption information is directly associated with the fee by obtaining the energy consumption fee table. The energy price difference in different time periods is clear at a glance in the energy consumption fee table, so that the user can select the most economical cleaning time period to reduce the cleaning cost. For example, in the case of different peak-valley electricity prices, the cleaning work can be arranged in the valley time by comparing the cleaning fees in different time periods, which can significantly reduce the cleaning cost.
