TECHNICAL FIELD

[0001] The present application relates to the technical field of drinking water safety, in particular to a drinking water equipment control method and device, drinking water equipment, computer readable storage medium and computer program product. BACKGROUND

[0002] With the continuous upgrading of consumer demand, desktop integrated drinking water machines are widely used, which can provide purified normal temperature pure water, hot water and ice water at the same time, meeting the diversified drinking water needs of users in scenarios such as home and office environment. In order to improve space utilization and ensure water quality safety, such equipment usually adopts a design that completely separates the raw water tank and the waste water tank. However, this design causes the waste water generated during water purification to be unable to be recycled, the water purification recycling rate is low, and long-term use causes significant waste of tap water resources.

[0003] Therefore, the prior art proposes a design scheme of changing the raw water tank and the waste water tank into a mixed structure, which purifies the mixed waste water and raw water again, aiming to improve the utilization rate of tap water of the whole machine. However, this improvement has brought a new technical problem: with the increase of the number of cycle purification, the raw water in the semi-separation water tank gradually increases in impurities, dissolved solids and microorganisms due to the continuous mixing of waste water, forming a cumulative effect of water quality deterioration. This not only increases the burden of the filter element, but also directly affects the quality of the final output pure water, which has a health and safety risk. Therefore, how to efficiently utilize water resources while ensuring the stability and safety of the water quality of the drinking water machine in long-term operation has become a key problem to be solved.

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0055] The drinking water equipment control method provided in this application embodiment can be applied to, for example... Figure 1The water drinking device shown in the figure. Among them, the water drinking device includes a reverse osmosis filter core 10 and a semi-separation raw wastewater tank 20, the semi-separation raw wastewater tank 20 includes a raw water chamber 21 and a wastewater chamber 22 which are at least partially communicated, the raw water chamber 21 is communicated with the reverse osmosis filter core 10 through a raw water waterway A, and the wastewater chamber 22 is communicated with the reverse osmosis filter core 10 through a wastewater waterway B; A wastewater electromagnetic valve 220 is arranged on the wastewater waterway B. It also includes a controller 30, and a state data acquisition module (not all devices are shown in the figure) connected with the controller 30, and the controller 30 is used to realize the control of the water drinking device according to the water drinking device control method provided by the embodiment of the application. The data storage system can store the data required by the controller 30 to process. The data storage system can be integrated on the controller 30, or placed on the cloud or other network servers.

[0056] Specifically, after the water drinking device enters the target running state, the controller 30 obtains the state data corresponding to the target running state through the state data acquisition module, and determines the current flushing parameter based on the state data corresponding to the target running state in the case that it is determined to perform filter core flushing; the flushing parameter includes the wastewater waterway opening degree; the wastewater waterway is controlled to be conducted through the wastewater waterway opening degree in the current flushing parameter, and the reverse osmosis filter core 10 is flushed through the raw water in the raw water waterway.

[0057] Among them, the controller 30 can be a control chip or a control circuit board arranged on the water drinking device, or an external control system realized based on wireless communication. The external control system can be realized through a terminal or a server and the like. The terminal can be but is not limited to various personal computers, notebook computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things device can be a smart sound box, a smart television, a smart air conditioner, a smart vehicle-mounted device, a projection device and the like. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device and the like. The head-mounted device can be a virtual reality (Virtual Reality, VR) device, an augmented reality (Augmented Reality, AR) device, smart glasses and the like. The server can be a stand-alone physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0058] In an exemplary embodiment, as Figure 2 shown, a water drinking device control method is provided, which is applied to the controller 30 in Figure 1 for example, including the following steps S202 to S206. Among them:

[0059] Step S202, after the water drinking device enters the target running state, the state data corresponding to the target running state is obtained.

[0060] It can be understood that the water drinking equipment specifically refers to an equipment with a reverse osmosis filtering function in the embodiments of the present application, which can purify raw water.

[0061] Among them, the water drinking equipment has multiple running states based on different running stages during the running process. The target running state refers to a key equipment running stage that may cause the risk of impurity concentration or penetration on the surface of the reverse osmosis membrane of the reverse osmosis filter element. The target running state at least includes any one or more of the following running states: a start water making state, a static state, and a water change prompt state, etc. Among them, the start water making state can be the moment when the user requests water making or the equipment automatically starts the water making process. The static state can be a stage in which the water making pressure stabilizing pump stops running after the end of a water making process, and the equipment is idle and waiting. The water change prompt state can be a stage in which the equipment detects that the water quality in the semi-separation raw wastewater tank is deteriorated or the water volume is insufficient, and thus sends a water change prompt signal to the user.

[0062] Specifically, after the water drinking equipment enters the target running state, that is, the water drinking equipment enters the key equipment running stage that may cause the risk of impurity concentration or penetration on the surface of the reverse osmosis membrane of the reverse osmosis filter element, the state data corresponding to the target running state needs to be further acquired to determine whether to flush the surface of the reverse osmosis membrane of the reverse osmosis filter element.

[0063] Among them, the state data corresponding to the target running state refers to specific parameter information for quantifying or characterizing the water quality risk degree in the target running state. It can be understood that the type and specific content of the above-mentioned state data correspond to the target running state, and the state data corresponding to different target running states can be the same or different, which can be set according to actual technical requirements. For example, the state data can include pressure data, flow data, time length data, and water quality data, etc. For example, the pressure data can be raw water inlet pressure, pre-reverse osmosis membrane pressure, wastewater pressure, etc. The flow data can be raw water instantaneous flow, cumulative water making volume, wastewater flow, etc. The time length data can be the time length of this continuous running, the static time length, the cumulative use time length of the filter element, the interval time length since the last flushing, etc. The water quality data can include inlet water quality data and outlet water quality data, etc.

[0064] For example, the state data corresponding to the start water making state can include but is not limited to: initial water making mark data representing whether this water making start is the first time, and raw water quality data in the current semi-separation raw wastewater tank. The state data corresponding to the static state can include but is not limited to: static time length. The state data corresponding to the water change prompt state can include but is not limited to: raw water quality data in the current semi-separation raw wastewater tank, and liquid level data of the semi-separation raw wastewater tank.

[0065] The type corresponding to the acquired state parameter is different, and different data acquisition methods can be selected for data acquisition. For example, pressure data, flow data, and water quality data can be read by setting corresponding sensors. For example, the time length data can be obtained by the internal timer of the controller.

[0066] In step S204, based on the state data corresponding to the target operating state, if it is determined that the filter core needs to be flushed, the current flushing parameter is determined. The flushing parameter includes the waste water path opening degree.

[0067] Specifically, after obtaining the state data corresponding to the target operating state, the controller can determine whether it is necessary to start the flushing operation of the reverse osmosis filter core according to the preset logical rule.

[0068] Correspondingly, in different target operating states, different preset logics for judgment can be provided to determine whether the filter core needs to be flushed. For example, the preset logic corresponding to the running time length can be used for judgment, for example, if the continuous running time length of the device exceeds a certain time length, the filter core flushing is triggered. The filter core flushing can also be triggered periodically according to the total use time length of the filter core. For example, the preset logic corresponding to the water quality change can be used for judgment. For example, if the change amount of the product water quality data relative to the influent water quality data exceeds a certain proportion, the filter core flushing is triggered. For example, the preset logic corresponding to the device state event can be used for judgment. For example, if the device is in standby mode for a long time, the filter core flushing is triggered periodically. For example, if the user triggers the flushing command through the key or the application program of the user terminal, the filter core flushing is triggered.

[0069] Further, the current flushing parameter refers to the control variable set for executing a flushing operation. It at least includes the waste water path opening degree. The waste water path opening degree refers to the parameter controlling the flow area of the waste water path, which determines the flow rate through the waste water path during flushing and directly affects the flow rate and intensity of flushing.

[0070] Wherein, the determination method of the current flushing parameter is not unique. For example, the waste water path opening degree can be obtained by hierarchical setting or linear correlation. The hierarchical setting can be to preset multiple levels of flushing modes, such as standard flushing and strong flushing, each mode corresponding to a fixed waste water electromagnetic valve opening degree (such as 50% opening degree and 100% opening degree). Finally, the corresponding flushing mode is selected according to the determined water quality risk level to determine the waste water path opening degree. Through linear correlation, the waste water path opening degree can be obtained in a certain corresponding relationship with other state data. For example, the waste water path opening degree and the raw water quality data are in a positive correlation function relationship, and finally the corresponding waste water path opening degree is determined according to the current state data.

[0071] Step S206, controlling the wastewater waterway to be conducted with the wastewater waterway opening degree in the current flushing parameter, and flushing the reverse osmosis filter core by the raw water in the raw water waterway.

[0072] Specifically, after obtaining the wastewater waterway opening degree, the controller can output a control signal (such as a PWM wave, a level signal) to the wastewater electromagnetic valve based on the wastewater waterway opening degree, and drive it to open to the wastewater waterway opening degree determined by the current flushing parameter, so as to control the wastewater waterway to be conducted at the corresponding opening degree. In this process, the controller starts the operation of the pressure stabilizing pump on the raw water waterway at the same time, and pressurizes the raw water in the semi-separation raw wastewater tank into the reverse osmosis filter core, and flows through the surface of the reverse osmosis membrane. Since the wastewater waterway is in the state of being conducted at a specific opening degree, the water flow can carry the impurities (such as heavy metal ions, colloids, bacteria, etc.) trapped and concentrated on the surface of the reverse osmosis membrane together, and quickly discharge them from the wastewater waterway back to the semi-separation raw wastewater tank, so as to achieve the purpose of cleaning the filter core.

[0073] It can be understood that the wastewater waterway opening degree in the current flushing parameter is a larger opening degree value than that in the normal water production state. In the normal water production state, the wastewater electromagnetic valve is usually controlled at a smaller opening degree (for example, in a half-open or throttling state at a low duty cycle), and the main purpose is to maintain the minimum transmembrane pressure difference required for the operation of the reverse osmosis membrane and produce a part of the concentrated wastewater. In contrast, during flushing, the core purpose of increasing the wastewater waterway opening degree is to quickly reduce the pressure on the water inlet side of the reverse osmosis membrane, so as to form a large-flow and high-flow-rate flushing water flow, which can more effectively flush and carry away the impurities attached to the surface of the reverse osmosis membrane, and strongly discharge them back to the semi-separation raw wastewater tank, so as to achieve more thorough membrane surface cleaning in a short time.

[0074] In one example, the flushing parameter can also include a flushing duration. Step S206 includes: controlling the wastewater waterway to be conducted for the flushing duration with the wastewater waterway opening degree in the current flushing parameter, and flushing the reverse osmosis filter core by the raw water in the raw water waterway.

[0075] Specifically, the flushing duration is the time duration of the flushing operation. It can be understood that the longer the flushing duration is, the more total water flows through the surface of the reverse osmosis membrane, and the more total impurities are carried away. Correspondingly, the controller can output a control signal to the wastewater electromagnetic valve based on the wastewater waterway opening degree, and drive it to open to the wastewater waterway opening degree determined by the current flushing parameter, so as to control the wastewater waterway to be conducted at the corresponding opening degree. Further, a timer is set or connected in the controller, and starts timing at the same time when the control instruction is output. When the set flushing duration is reached, the timer triggers an interruption or a signal, and the controller outputs a stop flushing instruction to reset the wastewater electromagnetic valve.

[0076] In an exemplary embodiment, the reverse osmosis filter core is communicated to the pure water tank through a pure water waterway; the state data corresponding to the target operating state further comprises pure water tank in-place data; the water dispenser control method further comprises: in the case that the pure water tank in-place data is in the in-place state, determining that filter core flushing is required.

[0077] Specifically, the pure water tank in-place data is state data representing whether the user correctly places the detachable water tank (pure water tank) for storing pure water at the designated water receiving position of the device; the controller can determine the pure water tank in-place data by whether it detects physical connection. It can be understood that the pure water tank in-place data is a Boolean quantity or a state code, indicating whether the pure water tank is in the in-place state or the out-of-place state.

[0078] It can be understood that during the flushing process, when the pressure stabilizing pump is started and the wastewater electromagnetic valve is opened at a large opening, the pressure on the water inlet side of the reverse osmosis membrane drops sharply, but the membrane itself is not absolutely impermeable to water flow. A small amount of water will still penetrate the reverse osmosis membrane under the driving force of the pressure difference and enter the pure water waterway. If the pure water tank connected to the pure water waterway is not in place (i.e., not installed) at this time, the water entering the pure water waterway will have no container to receive it and will overflow from the pure water outlet, causing water to accumulate inside the device or on the table, posing a safety hazard and affecting user experience.

[0079] Further, on the premise that the pure water tank is in the in-place state, the need for filter core flushing is determined according to other state parameters in the target operating state, the wastewater waterway is controlled to be conductive with the wastewater waterway opening degree in the current flushing parameter, and the reverse osmosis filter core is flushed with raw water in the raw water waterway, wherein a small amount of permeate pure water generated during the flushing process is safely collected in the in-place pure water tank.

[0080] The water dispenser control method described above, after the water dispenser enters the target operating state, obtains state data corresponding to the target operating state, determines the current flushing parameter in the case that filter core flushing is required based on the state data corresponding to the target operating state; the flushing parameter includes the wastewater waterway opening degree; the wastewater waterway is controlled to be conductive with the wastewater waterway opening degree in the current flushing parameter, and the reverse osmosis filter core is flushed with raw water in the raw water waterway. By obtaining state data corresponding to multiple target operating states, the risk of water quality degradation caused by the semi-separation of the raw wastewater tank structure is accurately identified, and flushing is dynamically triggered only when necessary, thereby fundamentally solving the contradiction between the improvement of utilization rate and the decline of pure water quality caused by the semi-separation of the water tank, and minimizing unnecessary flushing water consumption while ensuring the safety of terminal drinking water.

[0081] In an exemplary embodiment, the operating state of the water dispenser includes a start water production state; the state data corresponding to the start water production state includes initial water production marker data; and the flushing parameter further includes flushing duration. Exemplarily, as shown inFigure 3 As shown, the water equipment control method includes the following steps: S301: in the case that the target running state is the starting water production state, and the initial water production flag data is in the valid state, it is determined that the filter core flushing needs to be performed, and the flushing duration is determined as the first flushing duration.

[0082] The initial water production flag data is a flag bit, which is used to identify whether the current starting water production process belongs to the initial water production cycle. The initial water production flag data can be the water production cycle of the first power-on of the equipment, or the first water production cycle after the equipment changes the filter core. The initial water production flag data in the valid state means that the flag bit is set, indicating that this is the initial water production. Correspondingly, the initial water production flag data in the invalid state means that the flag bit is not set, indicating that this is not the initial water production.

[0083] Specifically, in the process node that the water equipment is converted from the non-water production state (such as standby, shutdown, flushing, fault state) to the normal water production state for the first time, that is, in the starting water production state, and at the same time, it is identified according to the initial water production flag data that it belongs to the initial water production cycle, it is determined that the filter core flushing needs to be performed. In this case, the flushing duration for the flushing operation can be set as the first flushing duration.

[0084] The first flushing duration is a fixed flushing duration preset for the initial water production scenario. The duration can be determined based on the experimental data of the specific type of reverse osmosis filter core, which is sufficient to ensure the initial wetting and pollution flushing of the reverse osmosis membrane. Correspondingly, after determining that the filter core flushing needs to be performed, the controller can output a control signal to the waste water electromagnetic valve based on the waste water path opening degree, to drive it to open to the waste water path opening degree determined by the current flushing parameter, to control the waste water path to be turned on at the corresponding opening degree. Further, a timer is set or connected in the controller, which starts timing at the same time as the control instruction is output. When the first flushing duration is reached, the timer triggers an interrupt or a signal, and the controller outputs a stop flushing instruction to reset the waste water electromagnetic valve.

[0085] In an exemplary embodiment, the state data corresponding to the starting water production state further includes raw water quality data. For example, as shown in the following table, the raw water quality data can be the turbidity of the raw water, and the first water quality threshold can be the turbidity threshold. Figure 3 As shown, the water equipment control method includes the following steps: S302: in the case that the target running state is the starting water production state, and the water quality difference between the raw water quality data and the first water quality threshold reaches the flushing condition, it is determined that the filter core flushing needs to be performed, and the second flushing duration is determined according to the water quality difference and the preset corresponding relationship between the water quality difference and the flushing duration.

[0086] The raw water quality data is a quantitative index for real-time representing the pollution degree of the water in the semi-separation raw wastewater tank. In an example, the raw water quality data is a raw water TDS value detected by a TDS (Total dissolved solids) sensor. The TDS sensor can be arranged on the raw water channel or in the semi-separation raw wastewater tank.

[0087] The first water quality threshold is a preset reference value for comparison with the current raw water quality data, which can be a reference TDS value representing the water quality of fresh tap water. The reference TDS value can be preset in the controller when the device is shipped, or can be a typical tap water TDS value obtained according to the user's location, or can be a real-time tap water TDS value detected at the tap water inlet pipe of the drinking water device.

[0088] Specifically, the water quality difference is the difference between the raw water quality data and the first water quality threshold, and the numerical difference obtained is used to quantify the pollution degree of the current raw water relative to fresh tap water.

[0089] Further, at the process node when the drinking water device is first converted from a non-water production state (such as standby, shutdown, flushing, fault state) to a normal water production state, i.e., in the starting water production state, and the water quality difference reaches the flushing condition, it is determined that the filter core needs to be flushed. In this case, the flushing time for the flushing operation can be determined as a second flushing time according to the water quality difference and a preset corresponding relationship between the water quality difference and the flushing time.

[0090] The flushing condition is a judgment standard for the water quality difference that needs to be met to trigger flushing. In an example, the water quality difference reaching the flushing condition can be that the water quality difference is greater than a preset water quality difference threshold. It can be understood that reaching this condition indicates that the current raw water quality has deteriorated significantly, and it is necessary to flush.

[0091] The preset corresponding relationship between the water quality difference and the flushing time is a rule for dynamically calculating or matching the required flushing time according to the water quality deterioration degree. The specific correspondence is the following adaptive principle: the greater the water quality difference, the longer the flushing time needs to be. The second flushing time is the flushing time calculated according to the specific water quality difference through the above corresponding relationship, and can be applicable to the current water quality condition. It can be understood that the second flushing time here can be a longer time than the first flushing time.

[0092] Correspondingly, after determining that the filter needs to be flushed, the controller can output a control signal to the wastewater electromagnetic valve based on the wastewater waterway opening degree, to drive the wastewater electromagnetic valve to open to the wastewater waterway opening degree determined by the current flushing parameter, so that the wastewater waterway is turned on at the corresponding opening degree. Further, a timer is set in the controller or connected to the controller, and the timer starts timing at the same time when the control instruction is output. When the second flushing time length is reached, the timer triggers an interrupt or a signal, and the controller outputs a stop flushing instruction to reset the wastewater electromagnetic valve.

[0093] In an exemplary embodiment, the operating state of the water drinking device includes a water making stop state; and the flushing parameter further includes a flushing time length. As shown in Figure 3 The water drinking device control method described above includes the following step S303: in the case where the target operating state is the water making stop state, it is determined that the filter needs to be flushed, and the flushing time length is determined as a third flushing time length.

[0094] The water making stop state refers to a transition stage in which the water drinking device is prepared to transit from the water making state to the standby or resting state after completing a continuous pure water making process. The triggering of the water making stop state is usually based on a water making completion signal or the action of stopping the operation of the pressure stabilizing pump.

[0095] Specifically, in the case where the target operating state is the water making stop state, it can be directly determined that the filter needs to be flushed. In this case, the flushing operation can be set with a flushing time length of the third flushing time length. It can be understood that the purpose of the present embodiment is to perform a flushing operation by default after each water making action, regardless of the current water quality data. In this way, the pollutants newly trapped and concentrated on the surface of the reverse osmosis membrane during the just completed water making period can be removed in time, so that these pollutants do not gradually penetrate the pure water side due to the system back pressure or concentration diffusion during the subsequent device resting period, thereby ensuring the freshness of the water quality at the start of the next water making (i.e., the first cup of water).

[0096] The third flushing time length is a fixed flushing time length preset for the water making stop scenario. The time length can be set based on the evaluation of the typical pollutant load in a single water making period, and is sufficient to perform an effective flushing of the surface of the reverse osmosis membrane. The specific time length of the third flushing time length can be the same as the first flushing time length, or can be shorter than the first flushing time length. Correspondingly, after determining that the filter needs to be flushed, the controller can output a control signal to the wastewater electromagnetic valve based on the wastewater waterway opening degree, to drive the wastewater electromagnetic valve to open to the wastewater waterway opening degree determined by the current flushing parameter, so that the wastewater waterway is turned on at the corresponding opening degree. Further, a timer is set in the controller or connected to the controller, and the timer starts timing at the same time when the control instruction is output. When the third flushing time length is reached, the timer triggers an interrupt or a signal, and the controller outputs a stop flushing instruction to reset the wastewater electromagnetic valve.

[0097] In an example embodiment, the running state of the water drinking device includes a static state, and the state data corresponding to the static state includes a static duration; the flushing parameter further includes a flushing duration. As shown in Figure 3 The water drinking device control method includes the following step S304: in the case that the target running state is the static state and the static duration reaches the preset static duration, it is determined that the filter core flushing is needed, and the flushing duration is determined as the fourth flushing duration.

[0098] The static state refers to that the water drinking device stops running after completing a flushing or water making operation, and no new water making or flushing instruction is received, and the device is in a standby stage of non-active work. Correspondingly, the static duration refers to the time length from the end of the last water making or flushing operation of the device, usually starting from the time when the pressure stabilizing pump stops, to the current time.

[0099] Specifically, when the static duration reaches the preset static duration after the water drinking device enters the static state, it is determined that the filter core flushing is needed. In this case, the flushing duration for the flushing operation is set as the fourth flushing duration. It can be understood that the present embodiment is aimed at solving the risk of secondary pollution of water quality caused by osmotic pressure during the idle period of the water drinking device.

[0100] The preset static duration is a preset time threshold, which represents the approximate time required for impurities (such as heavy metal ions, microorganisms, etc.) to start penetrating the reverse osmosis membrane and polluting the pure water side under the action of system back pressure and concentration difference diffusion in the static state. The specific value of the preset static duration can be determined based on the material properties, membrane performance and safety redundancy of the reverse osmosis membrane through preliminary tests.

[0101] The fourth flushing duration is a fixed flushing duration preset after the flushing triggered in the static state. The purpose is to flush back the pollutants that may have diffused to the surface of the reverse osmosis membrane after a long period of static state of the device, back to the semi-separation original wastewater tank, restore the clean state of the membrane interface, and ensure the water quality safety of subsequent water making. The specific duration of the fourth flushing duration can be the same duration as the first flushing duration, or other duration. Correspondingly, after determining that the filter core flushing is needed, the controller can output a control signal to the wastewater electromagnetic valve based on the wastewater waterway opening degree to drive it to open to the wastewater waterway opening degree determined by the current flushing parameter to control the wastewater waterway to be conducted at the corresponding opening degree. Further, a timer is set or connected in the controller, which starts timing at the same time as the output of the control instruction. When the fourth flushing duration is reached, the timer triggers an interrupt or a signal, and the controller outputs a stop flushing instruction to reset the wastewater electromagnetic valve.

[0102] In an exemplary embodiment, the operating state of the water drinking device includes a water change prompt state, and the state data corresponding to the water change prompt state includes the raw water level of the semi-separated original wastewater tank; the flushing parameter further includes a flushing duration. As shown in Figure 3 The water drinking device control method described above includes step S305: in the case where the target operating state is the water change prompt state and the raw water level of the semi-separated original wastewater tank is a low water level, it is determined that filter core flushing needs to be performed, and the flushing duration is determined to be a fifth flushing duration.

[0103] The water change prompt state refers to an operating state in which the water drinking device determines that the water in the semi-separated original wastewater tank is not suitable for continued circulation and purification, and user intervention (such as pouring, cleaning the water tank, and refilling fresh tap water) is required. After entering the water change prompt state, the controller usually sends a prompt to the user through sound, light, a display screen, and the like. The raw water level of the semi-separated original wastewater tank refers to the water height or capacity information of the semi-separated original wastewater tank detected in real time by a liquid level sensor. The controller can read the signal of the liquid level sensor in real time or periodically, and when the signal indicates that the liquid level has fallen below the low liquid level, the controller determines that the device enters the water change prompt state.

[0104] Specifically, in the case where the target operating state has entered the water change prompt state and the water change prompt state is determined by the raw water level of the semi-separated original wastewater tank falling below the low liquid level, it indicates that the amount of water available for use in the semi-separated original wastewater tank is about to be exhausted. In this case, the flushing duration for flushing operation can be set to the fifth flushing duration. While prompting the user to change the water, the filter core flushing of the fifth flushing duration is forcibly triggered, and the last remaining water amount is used to perform the most thorough and powerful flushing of the reverse osmosis membrane to remove long-term accumulated pollutants. In this way, not only the filter core can be protected, but also the risk of extremely high concentration of residual pollutants rapidly polluting the fresh water quality after new water is added can be prevented.

[0105] The fifth flushing duration is a fixed flushing duration preset for triggering the water change prompt state in the low liquid level. Considering that the water quality is poor and the pollutant load may be the largest at this time, the fifth flushing duration can be set to a relatively long value, which is greater than the remaining fixed flushing durations, to ensure sufficient flushing effect. At the same time, the wastewater waterway opening degree matched therewith can also be set to a large value (for example, 100% full opening) to form the maximum flushing flow rate.

[0106] Correspondingly, after determining that the filter element needs to be flushed, the controller can output a control signal to the wastewater electromagnetic valve based on the wastewater path opening degree, to drive the wastewater electromagnetic valve to open to the wastewater path opening degree determined by the current flushing parameter, so as to control the wastewater path to be turned on at the corresponding opening degree. Further, a timer is set in the controller or connected to the controller, and the timer starts timing when the control instruction is output. When the fifth flushing time length is reached, the timer triggers an interrupt or a signal, and the controller outputs a stop flushing instruction to reset the wastewater electromagnetic valve.

[0107] In an exemplary embodiment, the state data corresponding to the water change prompt state further includes raw water quality data. For example, as shown in FIG. 6, the water change prompt state is determined by the raw water quality data reaching the second water quality threshold value. Figure 3 As shown in FIG. 6, the water treatment device control method includes step S306: in the case that the target operating state is the water change prompt state and the raw water quality data reaches the second water quality threshold value, it is determined that the filter element needs to be flushed, and a sixth flushing time length is determined according to the raw water quality data and a preset corresponding relationship between water quality values and flushing time lengths.

[0108] The second water quality threshold value is a preset water quality critical value higher than the first water quality threshold value, representing the maximum water quality data safety upper limit allowed by the water treatment device. When the raw water quality data reaches the second water quality threshold value, it indicates that even if the raw water level in the semi-separation raw wastewater tank is sufficient, the water quality has been severely deteriorated, and the user must be prompted to change the water and perform deep cleaning. In one example, the second water quality threshold value can be determined according to the service life of the reverse osmosis filter element.

[0109] Specifically, in the case that the target operating state has entered the water change prompt state, and the water change prompt state is determined by the raw water quality data reaching the second water quality threshold value, it is determined that the filter element needs to be flushed, and a sixth flushing time length is determined for the flushing time length. In this case, it is indicated that even if the water amount in the semi-separation raw wastewater tank is sufficient, the real-time monitored raw water quality data indicates that the pollutant concentration has exceeded the limit for safe operation of the system (the second water quality threshold value), and the water change prompt state should be entered immediately, and a strong flushing that matches the current pollution level should be triggered. In this way, it can be prevented that the user continues to use the water source that has been severely polluted for purification due to not paying attention to the water amount in time.

[0110] The preset corresponding relationship between water quality values and flushing time lengths is a rule for calculating or matching the required flushing time length according to the raw water quality value. Specifically, the adaptive principle is that the larger the raw water quality value, the longer the flushing time length needs to be. The sixth flushing time length is the flushing time length calculated according to the specific raw water quality value through the above corresponding relationship, and can be applied to the current water quality condition. It can be understood that the sixth flushing time length can be a longer time length than the rest of the fixed flushing time lengths. At the same time, the wastewater path opening degree matched therewith can also be set to a larger value (for example, 100% full opening) to form the maximum flushing flow rate.

[0111] Correspondingly, after determining that the filter needs to be flushed, the controller can output a control signal to the wastewater electromagnetic valve based on the wastewater path opening degree to drive it to open to the wastewater path opening degree determined by the current flushing parameter, so as to control the wastewater path to be conducted at the corresponding opening degree. Further, a timer is set in the controller or connected to the controller, and the timer starts timing when the control instruction is output. After the set sixth flushing time is reached, the timer triggers an interrupt or a signal, and the controller outputs a stop flushing instruction to reset the wastewater electromagnetic valve.

[0112] It should be understood that, although each step in the flowchart involved in each of the above embodiments is displayed in sequence according to the arrow, these steps are not necessarily executed in the order indicated by the arrow. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other orders. Moreover, at least part of the steps in the flowchart involved in each of the above embodiments can include multiple steps or stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily sequential, but can be executed alternately or alternately with at least part of other steps or steps or stages in other steps.

[0113] In an exemplary embodiment, as shown in Figure 1 A water drinking device is provided, including a reverse osmosis filter 10 and a semi-separation raw wastewater tank 20, the semi-separation raw wastewater tank 20 including a raw water chamber 21 and a wastewater chamber 22 at least partially communicated, the raw water chamber 21 being communicated with the reverse osmosis filter 10 through a raw water path A, and the wastewater chamber 22 being communicated with the reverse osmosis filter 10 through a wastewater path B; a wastewater electromagnetic valve 220 is arranged on the wastewater path B. A controller 30 is further included, and a state data acquisition module connected with the controller 30, the controller 30 being used for realizing control of the water drinking device according to the water drinking device control method provided by the embodiments of the present application.

[0114] Specifically, after the water drinking device enters a target running state, the controller 30 acquires state data corresponding to the target running state through the state data acquisition module, and determines a current flushing parameter based on the state data corresponding to the target running state in a case where it is determined that the filter needs to be flushed; the flushing parameter includes a wastewater path opening degree; the wastewater path is controlled to be conducted at the wastewater path opening degree in the current flushing parameter, and the reverse osmosis filter 10 is flushed by raw water in the raw water path.

[0115] In an exemplary embodiment, as shown in Figure 4As shown, the semi-separation raw wastewater tank 20 includes a tank body 23 and a partition plate 24, which is arranged on the bottom wall 231 of the tank body 23 and separates the tank body 23 into a raw water chamber 21 and a wastewater chamber 22. In the height direction of the tank body 23, the partition plate 24 and the top wall of the tank body 23 have a communication gap therebetween to communicate the raw water chamber 21 and the wastewater chamber 22.

[0116] Specifically, the tank body 23 is the main structure of the semi-separation raw wastewater tank 20 and has basic water storage, pressure bearing and installation functions. The tank body 23 includes a bottom wall 231 and a top wall opposite to the bottom wall 231. The partition plate 24 is a vertical partition plate arranged on the bottom wall 231 of the tank body 23 and physically separates the originally integrated water tank cavity. The partition plate 24 is preferably integrally formed with the bottom wall 231 or fixedly connected by a sealing manner to ensure that an effective isolation barrier is formed in the bottom region.

[0117] Further, the raw water chamber 21 and the wastewater chamber 22 are two relatively independent chambers formed by the partition plate 24 in the tank body 23. The raw water chamber 21 is mainly used for storing and supplying tap water (raw water) to be purified. It is communicated with the raw water inlet of the reverse osmosis filter core through the raw water waterway A. The wastewater chamber 22 is mainly used for collecting and temporarily storing concentrated water (wastewater) discharged from the reverse osmosis filter core during the flushing or water production process. It is communicated with the wastewater backflow port of the reverse osmosis filter core through the wastewater waterway. In the height direction of the tank body 23, a specific space or channel is reserved between the upper edge of the partition plate 24 and the top wall of the tank body 23. This gap is the only fluid channel for communicating the raw water chamber 21 and the wastewater chamber 22.

[0118] It can be understood that, at the bottom, the partition plate 24 realizes the static separation of raw water and wastewater, preventing the large-area mixing of precipitated heavy impurities at the bottom. At the top, through the communication gap, the water bodies of the two chambers realize gas-phase communication and limited mixing above the liquid surface. When the water level on one side changes due to water use or backflow, the water on the other side can flow through the gap to balance the pressure and water level, and finally keep the liquid surface heights of the two chambers consistent. The wastewater generated during the operation of the equipment first flows into the wastewater chamber 22. Due to the existence of the communication gap, the water level of the wastewater chamber 22 rises, which pushes the water level of the raw water chamber 21 to rise synchronously, thereby realizing the gradual mixing of wastewater and raw water in the upper region of the tank. When fresh tap water is added, it also enters through the raw water chamber 21 and is further diluted with the mixed water.

[0119] In a specific embodiment, as shown in Figure 1 A water drinking device is provided, which includes a pressure stabilizing pump 1, a raw water quality sensor 2, a pure water tank 3, a reverse osmosis filter core 10, a semi-separation raw wastewater tank 20 and a wastewater electromagnetic valve 220. As shown in Figure 5As shown in the water flow schematic diagram of the reverse osmosis filter 10, the raw water is pressurized from the raw water inlet, passes through the reverse osmosis membrane 11, and then the pure water flows into the pure water tank 3 from the pure water outlet, and the waste water flows back to the semi-separation raw waste water tank 20 through the waste water channel.

[0120] Specifically, when producing water, the constant pressure pump 1 starts to work, the raw water is sucked into the reverse osmosis filter 10, the waste water electromagnetic valve 220 is semi-closed, the raw water is squeezed through the reverse osmosis membrane 11 by pressure, the produced pure water flows into the pure water tank 3 from the pure water outlet, and the produced waste water flows back to the semi-separation raw waste water tank 20 through the waste water channel. When flushing, the constant pressure pump 1 starts to work, the raw water is sucked into the reverse osmosis filter 10, the waste water electromagnetic valve 220 is fully opened, the pressure of the waste water channel is reduced, less water passes through the reverse osmosis membrane 11, and most of the water is used to carry back the impurities such as heavy metals and bacteria on the reverse osmosis membrane 11 to the semi-separation raw waste water tank 20, so as to ensure that no impurities penetrate into the pure water tank 3 during water production.

[0121] As shown in the water flow schematic diagram of the reverse osmosis filter 10, the raw water is pressurized from the raw water inlet, passes through the reverse osmosis membrane 11, and then the pure water flows into the pure water tank 3 from the pure water outlet, and the waste water flows back to the semi-separation raw waste water tank 20 through the waste water channel. Figure 6 As shown in the water flow schematic diagram of the reverse osmosis filter 10, the raw water is pressurized from the raw water inlet, passes through the reverse osmosis membrane 11, and then the pure water flows into the pure water tank 3 from the pure water outlet, and the waste water flows back to the semi-separation raw waste water tank 20 through the waste water channel.

[0122] Specifically, first, in the case of judging that the pure water tank is in place, the subsequent judgment process is entered. The raw water TDS value is collected by the raw water quality sensor. Before starting water production, it is judged whether it is the first time to produce water. When starting water production for the first time, flushing is entered and the flushing time is fixed. When starting water production for the second time, according to the comparison of the raw water TDS value and the tap water TDS value, if the difference between the two is less than the preset water quality difference threshold value, flushing is not started; if the difference between the two is greater than or equal to the preset water quality difference threshold value, according to the size of the raw water TDS value, the flushing time is changed; the greater the difference, the longer the flushing time. After water production is completed, automatic flushing is entered and the flushing time is fixed.

[0123] As shown in the water flow schematic diagram of the reverse osmosis filter 10, the raw water is pressurized from the raw water inlet, passes through the reverse osmosis membrane 11, and then the pure water flows into the pure water tank 3 from the pure water outlet, and the waste water flows back to the semi-separation raw waste water tank 20 through the waste water channel. Figure 7 As shown in the water flow schematic diagram of the reverse osmosis filter 10, the raw water is pressurized from the raw water inlet, passes through the reverse osmosis membrane 11, and then the pure water flows into the pure water tank 3 from the pure water outlet, and the waste water flows back to the semi-separation raw waste water tank 20 through the waste water channel.

[0124] Specifically, first, in the case of judging that the pure water tank is in place, the subsequent judgment process is entered. The raw water TDS value is collected by the raw water quality sensor. When it is detected that water change is needed, if the low liquid level triggers water change, flushing is entered and the flushing time is fixed. If the raw water TDS value reaches the second water quality threshold value to trigger water change, according to the size of the raw water TDS value, the flushing time is changed; the larger the raw water TDS value, the longer the flushing time.

[0125] A flushing control method during the standing process is also provided. Specifically, when the constant pressure pump stops, the timing starts, and when the constant pressure pump stop time ≥ t value, flushing is entered and the flushing time is fixed, and the t value can be determined according to the time of heavy metals, bacteria and other impurities penetrating the RO membrane.

[0126] In the embodiment, problems existing in various use scenarios are analyzed, and a flushing control method that can be adapted accordingly is given to ensure that wastewater is fully recycled, and pure water with good water quality can be obtained without affecting the service life of the filter element, thereby improving the utilization rate of tap water and improving the problem of water resource waste.
