The traditional method of cleaning the water supply device is to use simple cleaning equipment or chemicals for cleaning.

This method has certain risks. If the agent is used improperly, it may cause corrosion to the metal parts of the water supply device and affect the service life of the water supply device. The traditional method of cleaning the water supply device also uses a high-pressure water gun to flush the water channel of the water supply device, but this method may cause damage to certain fragile parts in the water channel.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1 As shown, Figure 1 A schematic diagram of a water circuit structure of a water supply device 1 provided in an embodiment of the present invention, wherein the water supply device 1 includes a water inlet module 10, a heat exchange module 21, a heating energy storage module 22, a water outlet module 30 and a control module 40;

[0026] The water inlet module 10 is connected to the heat exchange module 21, the heating energy storage module 22, and the water outlet module 30, and is used to control the water inlet amount of water entering the water supply device 1;

[0027] The heat exchange module 21 is connected to the heating energy storage module 22, the water inlet module 10 and the water outlet module 30.

[0028] A heating energy storage module 22, used to heat water entering the heating energy storage module 22 and then store it and / or store the water entering the heating energy storage module 22;

[0029] A water outlet module 30, used to output water meeting a preset water temperature;

[0030] The control module 40 is electrically connected to the water inlet module 10 , the heat exchange module 21 , the heating energy storage module 22 , and the water outlet module 30 . The control module 40 can be used to control the operation of the water inlet module 10 , the heat exchange module 21 , the heating energy storage module 22 , and the water outlet module 30 .

[0031] Among them, the heat exchange module 21 can be a device that transfers heat from one fluid to another fluid by means of heat conduction, convection and radiation. The larger the heat transfer area of ​​the heat exchange module, the more heat can be transferred under the same conditions, and the higher the heating efficiency is. In the single heat host water circuit solution provided in the present application, the heat transfer area of ​​the heat exchange module can be designed to be large enough to achieve the purpose of more effectively transferring heat to the fluid. In a possible example, the heat exchange module 21 and the heating energy storage module 22 can be used as heaters for heating in the water supply device 1, and the present application does not limit this.

[0032] In this embodiment, the water inlet amount of the water system of the water supply device is first controlled by the water inlet module 10, and the water entering the water system of the water supply device is heated by the heat exchange module 21, and the hot water obtained after heating is stored. Then, the water temperature is detected by the water outlet module 30, and water meeting the preset water temperature is output. Through effective temperature feedback and real-time adjustment mechanism, stable and efficient heating can be achieved, thereby achieving the purpose of more stably and efficiently supplying water meeting the preset temperature.

[0033] In the present application, the water supply device can be a water storage type electric water supply device, which includes a heating storage tank and a heat exchanger, wherein a heater is provided in the heating storage tank, and the heating medium of the heating storage tank can be water, oil, etc., which is not limited here. The heating storage tank is used to heat the water in the water supply device and store hot water, and the heat exchanger can further optimize the heat transfer.

[0034] Optionally, the heat exchanger adopts a plate heat exchanger. A plate heat exchanger is a highly efficient heat exchange device, which is composed of a series of metal plates with a certain corrugated shape stacked together, and narrow flow channels are formed between the plates. The fluid flows between the plates and heat is exchanged through the plates.

[0035] See also Figure 2 As shown, Figure 2 A flow chart of a method for cleaning a water channel of a water supply device provided in an embodiment of the present invention is provided. The method is used to clean a water supply device, wherein the water supply device includes a water inlet module, a heating module, and a water outlet module. The method includes the following steps:

[0036] S10: Acquire a water channel cleaning trigger signal, where the water channel cleaning trigger signal is used to instruct to clean the water channel of the heat exchanger of the water supply device.

[0037] The waterway cleaning trigger signal may be triggered automatically, or after receiving a user instruction. For example, the waterway cleaning trigger signal may be obtained at a preset time interval, and the preset time interval may be pre-set or system default, or the waterway cleaning trigger signal may be obtained at a non-fixed time interval. The user may also send an instruction to the water supply device, and the instruction is used to trigger the waterway cleaning trigger signal, and the waterway cleaning trigger signal is used to instruct the waterway cleaning of the water purification waterway of the heat exchanger of the water supply device.

[0038] In a specific implementation, a water channel cleaning trigger signal is obtained, and then the water channel cleaning of the water purification water channel of the heat exchanger of the water supply device can be started.

[0039] S20: Responding to the water channel cleaning trigger signal, obtaining first water channel state information of the heat exchanger.

[0040] The first waterway state information may include at least one of the following: first scale information, water flow velocity information, temperature information, pressure information, path information, etc., which are not limited here. The first scale information may include at least one of the following: scale type, scale thickness, scale location, etc., which are not limited here.

[0041] The first scale information can be detected by an ultrasonic sensor. For example, an ultrasonic sensor is set at one or more positions on the inner wall of the water purification waterway of the heat exchanger of the water supply device, and the first scale information of the water supply device is detected by the ultrasonic sensor. The water purification waterway of the heat exchanger includes a first heat exchange path and a second heat exchange path. The water output from the heating energy storage module 22 changes from hot to cold after passing through the first heat exchange path, and then returns to the heating energy storage module 22. The water input from the water inlet module to the second heat exchange path changes from cold to hot after passing through, and then enters the water outlet module 30, so that it can be heated by the second heat exchange path. The water flow rate information can be detected by one or more flow meters installed on the inner wall of the water purification waterway of the heat exchanger. For example, the average of one or more flow meters can be used as the water flow rate information. The temperature information can be detected by one or more temperature sensors installed on the inner wall of the water purification waterway of the heat exchanger. For example, the average of one or more temperature sensors can be used as the temperature information. The pressure information can be detected by one or more pressure sensors installed on the inner wall of the water purification channel of the heat exchanger. For example, the average of one or more pressure sensors can be used as the pressure information. The path information can be obtained from the structure of the water supply device itself. After the structure is determined, the path information can be determined. The path information can include at least one of the following: path length, path trajectory, path width, etc., which are not limited here.

[0042] S30: Determine water channel cleaning control information according to the first water channel state information and the property information of the heat exchanger.

[0043] The attribute information of the heat exchanger may include at least one of the following: the material of the heat exchanger, the size of the heat exchanger, the brand of the heat exchanger, the model of the heat exchanger, etc., which are not limited here.

[0044] Among them, the water channel cleaning control information may include at least one of the following: ultrasonic intensity information, ultrasonic frequency information, water channel cleaning path, water channel cleaning pressure, water channel cleaning direction, cleaning agent parameters corresponding to water channel cleaning, water channel cleaning mode, water channel cleaning sequence, water channel cleaning duration, etc., which are not limited here. The cleaning agent parameters corresponding to water channel cleaning may include at least one of the following: cleaning agent type corresponding to water channel cleaning, cleaning agent dosage corresponding to water channel cleaning, etc., which are not limited here. The water channel cleaning control information may include water channel cleaning control information at a time point, or water channel cleaning control information within a period of time.

[0045] In a specific implementation, the first water channel status information reflects the structure and characteristics of the water channel, and the attribute information of the heat exchanger reflects the characteristics of the water supply device. Furthermore, the water channel cleaning control information can be determined based on the first water channel status information and the attribute information of the heat exchanger. That is, the corresponding water channel cleaning control information can be determined based on the structure and characteristics of the water channel and the characteristics of the water supply device. Thus, the depth of the cleaning effect can be made to conform to the actual situation, which helps to ensure the cleaning effect.

[0046] S40: Cleaning the heat exchanger according to the water channel cleaning control information.

[0047] Among them, the heat exchanger can be cleaned according to the water channel cleaning control information. Since the water channel cleaning control information is deeply related to the structure and characteristics of the water channel and the characteristics of the water supply device, the depth of the cleaning effect can be made to conform to the actual situation, which helps to ensure the cleaning effect.

[0048] In a possible example, the above step S30, determining the water channel cleaning control information according to the first water channel state information and the property information of the heat exchanger, may include the following steps:

[0049] extracting first scale information from the first water channel state information;

[0050] determining first sub-cleaning control information according to the first scale information and the attribute information;

[0051] Perform cleaning prediction according to the first sub-cleaning control information to obtain particle information of scale residues after cleaning;

[0052] determining second sub-cleaning control information according to the particle information;

[0053] The first sub-cleaning control information and the second sub-cleaning control information are determined as the water channel cleaning control information.

[0054] The first sub-waterway cleaning control information may include at least one of the following: waterway cleaning path, waterway cleaning pressure, waterway cleaning direction, cleaning agent parameters corresponding to waterway cleaning, waterway cleaning mode, waterway cleaning sequence, waterway cleaning duration, etc., which are not limited here. The second sub-waterway cleaning control information may include at least one of the following: waterway cleaning path, waterway cleaning pressure, waterway cleaning direction, cleaning agent parameters corresponding to waterway cleaning, waterway cleaning mode, waterway cleaning sequence, waterway cleaning duration, etc., which are not limited here.

[0055] The particle information of the scale residue may include at least one of the following: particle size, particle quantity, particle density, particle diameter distribution information, etc., which is not limited here.

[0056] In a specific implementation, the first scale information can be extracted from the first water channel state information, and then the first sub-cleaning control information of the cleaning device can be determined according to the first scale information and the attribute information. For example, the mapping relationship between the scale information and the cleaning control information set can be used to determine the cleaning control information set corresponding to the first scale information based on the mapping relationship. The cleaning control information set can include multiple cleaning control information, each of which corresponds to one attribute information. Then, one cleaning control information corresponding to the attribute information of the heat exchanger can be used as the first sub-cleaning control information. The cleaning device can be an ultrasonic cleaning device.

[0057] Next, cleaning prediction can be performed based on the first sub-cleaning control information to obtain the particle information of the scale residue after cleaning. Specifically, the cleaning prediction can be performed using a prediction model. The input of the prediction model is the first sub-cleaning control information, and the output of the prediction model is the particle information of the scale residue. The prediction model can be an artificial intelligence model, for example, a convolutional neural network model. The prediction model can be obtained by training the convolutional neural network model using the cleaning control information and the corresponding particle information of the scale residue.

[0058] Next, since different particle information can correspond to different cleaning control information, that is, the mapping relationship between the preset particle information and the cleaning control information can be pre-stored, and then, based on the mapping relationship, the particle information of the scale residue after cleaning can correspond to the second sub-cleaning control information, and the first sub-cleaning control information and the second sub-cleaning control information can be determined as the waterway cleaning control information. That is, the first sub-cleaning control information and the second sub-cleaning control information can be understood as two stages of waterway cleaning, the first stage uses the first sub-cleaning control information for waterway cleaning, and the second stage uses the second sub-cleaning control information for waterway cleaning.

[0059] On the one hand, since the water channel cleaning control information in the first stage is related to the water quality characteristics, the degree of scale on the inner wall, and the characteristic depth of the water supply device, the depth of the cleaning effect can be made to conform to the actual situation, which helps to ensure the cleaning effect. On the other hand, considering that there may still be particle information of scale residues after cleaning, that is, in the second stage, the second sub-cleaning control information is used to perform water channel cleaning based on the characteristic depth of scale residues, so as to further improve the water channel cleaning effect and ensure the cleaning depth.

[0060] In a possible example, determining first sub-cleaning control information of a cleaning device according to the first scale information and the attribute information includes:

[0061] determining cleaning water flow information and / or cleaning water temperature information according to the first scale information;

[0062] Determine the number of cleaning times according to the attribute information;

[0063] The first sub-wash control information is determined at least according to the wash water flow information, the wash number information and / or the wash water temperature information.

[0064] In the specific cleaning, the scale can be removed by hot and cold shock, so as to perform cleaning. At this time, it is necessary to determine the temperature difference, flow rate, flow rate, and flushing times when performing hot and cold control.

[0065] Specifically, the washing water flow information and the washing water temperature information can be determined according to the first scale information. Specifically, the washing water temperature information and the washing water flow information can be determined according to the scale thickness in the first scale information. The greater the scale thickness, the greater the water temperature difference in the washing water temperature information, and the greater the water flow speed and flow rate in the washing water flow information; the smaller the scale thickness, the smaller the water temperature difference in the washing water temperature information, and the smaller the water flow speed and flow rate in the washing water flow information. The water flow speed, flow rate, etc. can be controlled by a water pump.

[0066] Since the attribute information of the heat exchanger can characterize the usage time, usage condition, and aging degree of the heat exchanger, the cleaning frequency information can be determined based on the usage time, aging degree, etc. Specifically, the longer the usage time, the greater the cleaning frequency; the shorter the usage time, the smaller the cleaning frequency; since the higher the aging degree, the higher the possibility of damage, therefore, the higher the aging degree, the smaller the cleaning frequency, and the lower the aging degree, the greater the cleaning frequency.

[0067] After determining the washing water flow information, the washing number information and / or the washing water temperature information, the corresponding water pump control parameters can be determined according to the washing water flow information, the washing number information and / or the washing water temperature information, thereby obtaining the first sub-washing control information. Specifically, the first sub-washing control information can be obtained by querying a table method or the like.

[0068] In a possible example, determining first sub-cleaning control information of a cleaning device according to the first scale information and the attribute information includes:

[0069] Determine reference ultrasonic wave generation intensity information and ultrasonic wave generation frequency information according to the first scale information;

[0070] determining intensity adjustment information according to the attribute information;

[0071] Adjust the reference ultrasonic wave generation intensity information according to the intensity adjustment information to obtain first ultrasonic wave generation intensity information;

[0072] The first ultrasonic wave generation intensity information and the ultrasonic wave generation frequency information are determined as first sub-cleaning control information.

[0073] In a specific implementation, the mapping relationship between the preset scale information and the ultrasonic generation intensity information can be pre-stored, and then, the reference ultrasonic generation intensity information corresponding to the first scale information can be determined based on the mapping relationship. The mapping relationship between the preset scale information and the ultrasonic generation frequency information can also be pre-stored, and then, the ultrasonic generation frequency information corresponding to the first scale information can be determined based on the mapping relationship.

[0074] Next, the mapping relationship between the preset attribute information and the intensity adjustment information can be pre-stored, that is, the intensity adjustment information corresponding to the attribute information of the heat exchanger can be determined based on the mapping relationship, and the value range of the intensity adjustment information can be -0.1 to 0.1. The reference ultrasonic wave generation intensity information is then adjusted according to the intensity adjustment information to obtain the first ultrasonic wave generation intensity information, that is, the first ultrasonic wave generation intensity information = (1 + intensity adjustment information) * reference ultrasonic wave generation intensity information. Finally, the first ultrasonic wave generation intensity information and the ultrasonic wave generation frequency information can be determined as the first sub-cleaning control information. In this way, the first-stage waterway cleaning control information is related to the water quality characteristics, the degree of inner wall scale, and the characteristic depth of the water supply device, so that the depth of the cleaning effect can be made to conform to the actual situation, which helps to ensure the cleaning effect.

[0075] In a possible example, the above step of determining the second sub-cleaning control information according to the particle information may include the following steps:

[0076] determining particle diameter distribution information according to the particle information;

[0077] determining first washing water flow velocity information according to a diameter distribution concentration area in the particle diameter distribution information;

[0078] determining a maximum particle diameter from the particle diameter distribution information;

[0079] determining flow rate adjustment information according to the maximum particle diameter;

[0080] Using the flow rate adjustment information to adjust the first washing water flow rate information to obtain second washing water flow rate information;

[0081] The second wash water flow rate information is determined as the second sub-wash control information.

[0082] In a specific implementation, the particle diameter distribution information can be determined based on the particle information, and then the first cleaning water flow rate information can be determined based on the diameter distribution concentration area in the particle diameter distribution information, so that the cleaning water flow rate is consistent with the particle size, thereby ensuring the cleaning effect. Next, the maximum particle diameter is determined from the particle diameter distribution information. The maximum particle diameter often determines the cleaning effect of the scale that is more difficult to clean to a certain extent. The mapping relationship between the preset particle diameter and the flow rate adjustment information can be pre-stored, and then the flow rate adjustment information corresponding to the maximum particle diameter can be determined based on the mapping relationship. The value range of the flow rate adjustment information can be -0.24 to 0.24. The flow rate adjustment information is then used to adjust the first cleaning water flow rate information to obtain the second cleaning water flow rate information, the second cleaning water flow rate information = (1 + flow rate adjustment information) * first cleaning water flow rate information, the second cleaning water flow rate information can be understood as the minimum water flow rate that can clean up the largest particle diameter, and then the second cleaning water flow rate information is determined as the second sub-cleaning control information. In the second stage, the second sub-cleaning control information is used to perform water channel cleaning based on the characteristic depth of scale residues, so as to further improve the water channel cleaning effect and ensure the cleaning depth.

[0083] In a possible example, the above step of performing cleaning prediction according to the first sub-cleaning control information to obtain particle information of scale residues after cleaning may include the following steps:

[0084] Determining the shedding time when all scale is shedding according to the first sub-cleaning control information;

[0085] The particle information of the scale residue is determined according to the shedding time.

[0086] In a specific implementation, the longer the particles have been detached, the easier it is to be broken into pieces, including collisions between particles and breakage after receiving ultrasonic vibrations.

[0087] Among them, in the specific implementation, the mapping relationship between the preset cleaning control information and the shedding speed can be pre-stored, and then, the target shedding speed (shedding progress) corresponding to the first sub-cleaning control information can be determined based on the mapping relationship. The mapping relationship between the preset scale information and the shedding difficulty value can also be pre-stored to determine the first shedding difficulty value corresponding to the first scale information, and then the shedding time is determined according to the shedding difficulty value and the shedding speed. For example, the shedding difficulty value is 10, and the shedding difficulty value is 2 / min, then 10 / (2 / min)=5min.

[0088] In the specific implementation, the mapping relationship between the preset shedding time and the particle information can also be pre-stored, and then the particle information of the scale residue corresponding to the shedding time can be determined based on the mapping relationship. Not only can the shedding time when all the scale is shedding be determined based on the first sub-cleaning control information, but also the corresponding particle information can be determined based on the shedding time when all the scale is shedding. In this way, the particle information can be accurately determined to pave the way for the second-stage water channel cleaning, thereby helping to use the second sub-cleaning control information to perform water channel cleaning based on the characteristic depth of the scale residue in the second stage, further improving the water channel cleaning effect and ensuring the cleaning depth.

[0089] In a possible example, after the heat exchanger is cleaned according to the water path cleaning control information, the following steps may also be included:

[0090] Obtaining status information of the second water path of the heat exchanger;

[0091] If the second water channel status information indicates that the scale has not been cleaned, the heat exchanger is cleaned for the second time.

[0092] The second waterway state information may include at least one of the following: second scale information, water flow velocity information, temperature information, pressure information, path information, etc., which are not limited here. The second scale information may include at least one of the following: scale type, scale thickness, scale location, etc., which are not limited here.

[0093] Among them, the second scale information can be detected by an ultrasonic sensor. For example, an ultrasonic sensor is set at one or more positions on the inner wall of the clean water channel of the heat exchanger of the water supply device, and the first scale information of the water supply device is detected by the ultrasonic sensor. The water flow rate information can be detected by one or more flow meters installed on the inner wall of the clean water channel of the heat exchanger. For example, the average of one or more flow meters can be used as the water flow rate information. The temperature information can be detected by one or more temperature sensors installed on the inner wall of the clean water channel of the heat exchanger. For example, the average of one or more temperature sensors can be used as temperature information. The pressure information can be detected by one or more pressure sensors installed on the inner wall of the clean water channel of the heat exchanger. For example, the average of one or more pressure sensors can be used as pressure information. The path information can be obtained from the structure of the water supply device itself. If the structure is certain, the path information is certain. The path information may include at least one of the following: path length, path trajectory, path width, etc., which are not limited here.

[0094] In a specific implementation, the second water channel status information of the heat exchanger can be obtained. If the second water channel status information indicates that the scale has not been cleaned, the heat exchanger is cleaned for the second time, thereby ensuring the cleaning effect.

[0095] In a possible example, the water supply device includes: a water inlet module, a heat exchange module, a heating energy storage module and a water outlet module, the water inlet module is connected with the heat exchange module, the heating energy storage module and the water outlet module, the heat exchange module is connected with the heating energy storage module, the water inlet module and the water outlet module, the heat exchange module includes a heat exchanger, and the heat exchanger includes a plate heat exchanger.

[0096] In the embodiment of the present application, the amount of water entering the water system of the water supply device is first controlled by the water inlet module, and the water entering the water system of the water supply device is heated by the heating module, and the water obtained after heating is stored. Then, the water temperature is detected by the water outlet module, and water meeting the preset temperature is output, so as to achieve stable heating of the water entering the water system of the water supply device, and effectively perform temperature feedback and real-time adjustment mechanism, thereby achieving the purpose of more stably supplying water meeting the preset temperature.

[0097] In a possible example, the water in the water inlet module can also be heated by the heating module to maintain the temperature of the water during the cleaning process, and use thermal energy to assist in removing sediments. Specifically, the heating module includes a heating reservoir and a heat exchanger. The heating reservoir is the main heating element, and a heater is provided inside it, which can convert electrical energy into thermal energy to heat the water stored therein, while the heat exchanger plays a role in heat exchange in the water system, which can transfer the heat of the heated water in the heating reservoir to other parts that need to be heated, or use its own heat exchange characteristics to assist in maintaining the water temperature during the cleaning process.

[0098] For example, in the early stage of cleaning the water supply device, when there are many and stubborn sediments in the waterway, the water temperature can be raised to the maximum operating temperature allowed by the heating reservoir to ensure heating safety. This temperature can exert the softening and dissolving effect of heat energy on sediments, such as calcium carbonate, magnesium hydroxide and other sediments. When it is monitored that the impurity content in the water is gradually decreasing, indicating that the sediment is reduced, the water temperature can be appropriately lowered to reduce energy consumption on the one hand and to avoid long-term damage to the water supply device components caused by excessively high temperatures on the other hand.
