Description

Technical Field

[0001] The present application relates to the field of water purification technology, and in particular to a control method, device, equipment and storage medium for a water purifier. Background Art

[0002] Instant water purifiers are now widely used in our daily lives. Instant water purifiers are household appliances that combine instant water purification and rapid heating. They are ready for immediate use, with precise temperature control, making them suitable for time-sharing water use.

[0003] Hot water is provided to users by heating water flowing through the heating pipes. Over time, the solubility of salts such as calcium carbonate and magnesium sulfate in the water decreases as the temperature rises, making crystals more likely to form in the hot water area. Furthermore, the maximum water outlet temperature set by the user is often above 95°C, which can easily cause scaling in the heating pipes, posing a risk of compromising water quality.

[0004] In the prior art, after a machine has been used for a long time, the heating pipe needs to be descaled and maintained, which has high labor costs and complicated operations, increasing maintenance costs.

DETAILED DESCRIPTION

[0086] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0087] With the increasing demand for water experience, instant water purifiers have become widely popular. Their heating method is to heat the water flowing through the heating tube. Due to long-term heating, the solubility of salts such as calcium carbonate and magnesium sulfate in the water decreases with increasing temperature (for example, the solubility of calcium carbonate at 80°C is only 1 / 5 of that at room temperature), making it easier for crystals to adhere in high-temperature areas, posing a risk of scaling in the heating tube. The maximum water outlet temperature set by the user is often above 95°C, and the risk of scaling in the heating tube is even greater at high temperatures. The current practice is that after the machine has been used for a long time, a service technician will visit the site to maintain the heating tube. The labor cost of on-site maintenance is high and the operation is complicated.

[0088] Therefore, in order to improve the descaling efficiency and meet users' requirements for water quality, there is an urgent need for an automatic descaling control method to achieve efficient descaling of water purifiers.

[0089] The present invention provides a control method for a water purifier. The machine accumulates the heating temperature and working time of the heating pipe, calculates the estimated scaling information, and if the estimated scaling information meets the scaling conditions, determines that the heating pipe needs to be descaled. After the user finishes using hot water, the descaling is automatically performed according to the descaling control information, thereby improving the efficiency and intelligence of the water purifier descaling. Figure 1 , the control method of the water purifier includes steps S101 to S109.

[0090] In step S101, in response to a heating end instruction, historical heating control information of the water purifier is acquired; the historical heating control information includes historical heating duration and historical target temperature.

[0091] In a possible implementation, the water purifier includes a heating device.

[0092] The obtaining of historical heating control information of the water purifier includes:

[0093] In response to a heating start instruction, starting the heating device; the heating start instruction includes a preset water outlet temperature;

[0094] Controlling the heating device to heat so that the outlet water temperature of the water purifier reaches the preset outlet water temperature;

[0095] In response to the heating end instruction, turning off the heating device;

[0096] Determining the duration from starting the heating device to shutting down the heating device as the historical heating duration;

[0097] Determining the preset outlet water temperature as the historical target temperature;

[0098] The historical heating duration and the historical target temperature are determined as the historical heating control information.

[0099] In one possible implementation, the heating start instruction indicates that the object needs to heat water at the current time. When hot water is needed, the object operates the water purifier according to the water demand to generate the heating start instruction, which is used to instruct the heating device of the water purifier to turn on.

[0100] In one possible implementation, the heating end instruction indicates that the object has finished using hot water at the current time. When the object has finished using hot water, the object operates the water purifier to generate the heating end instruction, which is used to instruct the heating device of the water purifier to turn off.

[0101] In a possible implementation, the heating start instruction includes a preset water outlet temperature, where the preset water outlet temperature is a target water outlet temperature set for each water use by the subject.

[0102] In a possible implementation, in response to the heating start instruction, the heating device is started and controlled to perform heating so that the outlet water temperature of the water purifier is a preset outlet water temperature corresponding to the heating start instruction.

[0103] In one possible implementation, in response to the heating end instruction, the heating device is turned off, the preset water outlet temperature corresponding to the heating start instruction is recorded as T, and the time from the start of the heating device to the shutdown of the heating device is recorded as t. The historical heating time t and the historical target temperature T for the current heating are determined as the historical heating control information.

[0104] In one possible implementation, there may be multiple pieces of historical heating control information, each piece of which corresponds to the historical heating duration and the historical target temperature for each heating event. Specifically, the historical heating control information includes outlet water temperature T1 and operating time t1 at outlet water temperature T1, outlet water temperature T2 and operating time t2 at outlet water temperature T2, ... outlet water temperature Tn and operating time tn at outlet water temperature Tn.

[0105] In one possible implementation, Figure 2 As shown, the water purifier includes a water inlet valve and a water purification device, the water purification device includes a wastewater valve and a clean water outlet, the wastewater valve is used to discharge wastewater into the sewer, and the clean water outlet is used to output water purified by the water purification device.

[0106] In one possible implementation, Figure 2As shown, the water purifier includes a sterilization device, which is connected to the purified water outlet. The water outlet of the sterilization device is respectively connected to the water outlet and the normal temperature water tank, and the normal temperature water tank is connected to the heating device through a water pump.

[0107] In one possible implementation, Figure 2 As shown, a first temperature sensor is provided near the water inlet of the heating device, and a second temperature sensor is provided near the water outlet of the heating device. The first temperature sensor is used to detect the water inlet temperature of the heating device, and the second temperature sensor is used to detect the water outlet temperature of the heating device.

[0108] In a possible implementation, the second temperature sensor detects the outlet water temperature of the heating device to obtain the historical heating time and the historical target temperature.

[0109] In this implementation, in response to the heating end instruction, the historical heating control information of the water purifier is obtained. The historical heating control information includes the historical heating time and the historical target temperature, which facilitates the subsequent estimation of scaling information based on the above information and improves the accuracy of automatic descaling.

[0110] In step S103, an estimation is performed based on the historical heating time and the historical target temperature to obtain estimated scaling information of the water purifier.

[0111] In a possible implementation, the estimating based on the historical heating time and the historical target temperature to obtain the estimated scaling information of the water purifier includes:

[0112] Obtaining a target temperature scaling coefficient corresponding to the historical target temperature;

[0113] The estimated scaling information is obtained by multiplying the historical heating time, the historical target temperature, and the target temperature scaling coefficient.

[0114] In one possible implementation, the target temperature scaling coefficient represents the likelihood that soluble salts (such as calcium carbonate and calcium sulfate) in the solution will precipitate and adhere to the tube walls of the heating device at the historical target temperature. Specifically, the scaling coefficient varies at different temperatures; a higher scaling coefficient indicates a greater scaling risk.

[0115] In a possible implementation, the target temperature scaling coefficient corresponding to the historical target temperature is obtained by querying a preset scaling coefficient table. Specifically, the preset structural coefficient table is constructed based on multiple temperatures and the scaling coefficient corresponding to each temperature.

[0116] In one possible implementation, the historical heating time, the historical target temperature, and the target temperature scaling coefficient are multiplied to obtain the estimated scaling information. Specifically, the estimated scaling information H is calculated as follows:

[0117] H=A*T*t

[0118] in,

[0119] t is the historical heating time,

[0120] T is the historical target temperature,

[0121] A is the target temperature scaling coefficient.

[0122] In a possible implementation, the estimated scaling information H may also be calculated as follows:

[0123] H=A1*T1*t1+A2*T2*t2+…+An*Tn*tn

[0124] in,

[0125] T1, T2…Tn are the historical target temperatures for multiple heatings.

[0126] t1, t2…tn are the historical heating times corresponding to T1, T2…Tn respectively.

[0127] A1, A2…An are the target temperature scaling coefficients at T1, T2…Tn respectively.

[0128] In this implementation, the estimated scaling information of the water purifier is determined based on the historical heating time, the historical target temperature and the target temperature scaling coefficient. Based on the scaling coefficient at different temperatures, the scaling information of each heating stage is estimated and accumulated, thereby improving the accuracy of determining the scaling condition of the water purifier.

[0129] In a possible implementation, the method further includes:

[0130] In a case where the estimated structural information is greater than a preset descaling threshold, determining that the estimated structural information satisfies the preset descaling condition;

[0131] In a case where the estimated structural information is less than or equal to the preset descaling threshold, it is determined that the estimated structural information does not meet the preset descaling condition.

[0132] In a possible implementation, the preset descaling threshold is obtained based on testing in a laboratory environment.

[0133] In a possible implementation, when the estimated structural information is greater than the preset descaling threshold, it is determined that the heating device needs to be descaled, that is, the preset descaling condition is met.

[0134] In a possible implementation, when the estimated structural information is less than or equal to the preset descaling threshold, it is determined that the heating device does not need to be descaled, that is, the preset descaling condition is not met.

[0135] In this implementation, whether the water purifier needs to be descaled is determined based on the comparison result between the estimated scaling information and the preset descaling threshold, thereby improving the efficiency of descaling of the water purifier.

[0136] In a possible implementation, the method further includes:

[0137] In a case where the estimated structural information does not satisfy the preset descaling condition, determining that the estimated scaling information is cumulative scaling information;

[0138] When the heating start instruction is received again, in response to the re-received heating start instruction, the heating device is started, and the heating device is repeatedly controlled to perform heating until the estimated scaling information of the water purifier is obtained;

[0139] The sum of the accumulated scaling information and the estimated scaling information is used as the estimated scaling information;

[0140] Until the estimated scaling information meets the preset descaling condition.

[0141] In a possible implementation, when the estimated structural information does not meet the preset descaling condition, the estimated scaling information H is obtained by performing cumulative calculation based on the following formula:

[0142] H=A1*T1*t1+A2*T2*t2+…+An*Tn*tn

[0143] in,

[0144] T1, T2…Tn are the historical target temperatures for multiple heatings.

[0145] t1, t2…tn are the historical heating times corresponding to T1, T2…Tn respectively.

[0146] A1, A2…An are the target temperature scaling coefficients at T1, T2…Tn respectively.

[0147] In a possible implementation, when the cumulatively calculated estimated scaling information satisfies the preset descaling condition, it is determined that the heating device needs to be descaled, that is, the estimated scaling information satisfies the preset descaling condition.

[0148] In this implementation, when the estimated scaling information indicates that the water purifier does not currently need to perform descaling operations, the descaling logic of the water purifier is not executed. Descaling is performed only after the accumulated estimated scaling information meets the preset descaling conditions, thereby improving the accuracy of automatic descaling.

[0149] In step S105, when the estimated structural information satisfies the preset descaling condition, the current water output status information of the water purifier is obtained.

[0150] In a possible implementation, the current water outlet status information of the water purifier indicates whether the water purifier is outlet.

[0151] In a possible implementation, when the water purifier is in a water outlet closed state, that is, when the water purifier is not currently discharging water, the current water outlet state information is determined to be the first water outlet state.

[0152] In a possible implementation, when the user turns off water use, it is determined that the water purifier is in a water outlet closed state.

[0153] In a possible implementation, when the water purifier is in a water outlet-on state, that is, when the water purifier is currently outlet water, the current water outlet state information is determined to be the second water outlet state.

[0154] In a possible implementation, when the user starts using water, it is determined that the water purifier is in a water outlet start state.

[0155] In step S107, descaling control information for the water purifier is determined based on the current water outlet status information.

[0156] In a possible implementation, the current water outlet status information includes a first water outlet status and a second water outlet status, wherein the first water outlet status indicates that the water purifier is in a water outlet closed state, and the second water outlet status indicates that the water purifier is in a water outlet opened state.

[0157] The determining of descaling control information for the water purifier based on the current water outlet state information includes:

[0158] When the current water outlet state information is the first water outlet state, determining that the descaling control information is the first descaling control information, the first control information indicating that descaling is turned on;

[0159] When the current water outlet state information is the second water outlet state, the descaling control information is determined to be second control information, and the second control information indicates waiting for the water purifier to switch to the first water outlet state.

[0160] In a possible implementation, when the current water outlet status information is the first water outlet status, that is, the water purifier is not currently outlet water, it is determined that the water purifier meets the descaling condition, the descaling control information is determined to be the first descaling control information, and descaling is started.

[0161] In one possible implementation, when the current water outlet status information is the second water outlet status, that is, the water purifier is currently outlet water, it is determined that the water purifier does not meet the descaling conditions, the descaling control information is determined to be the second control information, and the water purifier is waited to switch to the first water outlet status.

[0162] In this implementation, the descaling operation is performed after the water purifier finishes discharging water, which does not affect the user's normal use and improves the user experience.

[0163] In step S109, the water purifier is controlled according to the descaling control information.

[0164] In one possible implementation, the water purifier includes a water pump and a drainage pipe, the water pump is connected to the water inlet of the heating device, and the water outlet of the heating device is connected to the water outlet of the water purifier and the drainage pipe respectively through a three-way valve;

[0165] The controlling the water purifier according to the descaling control information includes:

[0166] When the descaling control information is the first control information, based on the three-way valve, controlling the water outlet of the heating device to be connected to the drainage pipe, and the water outlet of the heating device to be disconnected from the water outlet of the water purifier;

[0167] determining a current number of repetitions based on the preset outlet water temperature;

[0168] After the water pump is turned on for a preset time, the water pump is turned off;

[0169] After the water pump is turned off for a preset off time, the steps of repeatedly turning on the water pump and then turning off the water pump after the preset on time has passed;

[0170] Until the number of repetitions meets the current number of repetitions, based on the three-way valve, the water outlet of the heating device is controlled to be disconnected from the drainage pipe, and the water outlet of the heating device is connected to the water outlet of the water purifier.

[0171] In one possible implementation, Figure 2As shown, the water purifier includes a water pump and a drainage pipe. The water pump is connected to the water inlet of the heating device, and the water outlet of the heating device is connected to the water outlet of the water purifier and the drainage pipe respectively through a three-way valve.

[0172] In a possible implementation, when the descaling control information is the first control information, the three-way valve is opened and switched to the drainage pipeline so that the water outlet of the heating device is connected to the drainage pipe and the water outlet of the heating device is not connected to the water outlet of the water purifier.

[0173] In a possible implementation, the current number of repetitions N is determined based on the preset outlet water temperature T. The current number of repetitions N is calculated as follows:

[0174] N=B / T

[0175] Wherein, B is the preset coefficient and T is the preset water outlet temperature.

[0176] In a possible implementation, the current number of repetitions N is related to the preset outlet water temperature T. The lower the temperature, the greater the number of cycles. This is because the lower the temperature of the heating device, the smaller the stress after passing cold water, and the more difficult it is to break the scale.

[0177] In a possible implementation, when the estimated structural information is accumulated after multiple heatings, the preset outlet water temperature is the most recent preset outlet water temperature that meets the preset descaling condition.

[0178] In one possible implementation, the water pump is turned on for a preset on time, then turned off. After the water pump is turned off for the preset off time, the steps of turning on the water pump for a preset on time, then turning off the water pump are repeated. Specifically, the water pump is turned on at maximum power for 3 seconds, then turned off for 2 seconds, and then turned on at maximum power for 3 seconds in a cycle. The continuous impact of the water flow is conducive to the removal of scale.

[0179] In one possible implementation, when the number of repetitions meets the current number of repetitions, the three-way valve is closed and switched to the water outlet connected to the water purifier, so that the water outlet of the heating device is not connected to the drainage pipe, and the water outlet of the heating device is connected to the water outlet of the water purifier.

[0180] In this implementation, the water purifier is controlled according to the descaling control information, and the descaling cleaning effect is improved through multiple flushing.

[0181] The above-mentioned embodiments of the present application have the following beneficial effects: the embodiments of the present application obtain the historical heating control information of the water purifier in response to the heating end instruction; the historical heating control information includes the historical heating time and the historical target temperature; the estimated scaling information of the water purifier is obtained based on the historical heating time and the historical target temperature; the current water outlet status information of the water purifier is obtained when the estimated structural information meets the preset descaling condition; the descaling control information of the water purifier is determined based on the current water outlet status information; the water purifier is controlled according to the descaling control information. The machine accumulates the heating temperature and working time of the heating pipe to calculate the estimated scaling information. If the estimated scaling information meets the scaling condition, it is determined that the heating pipe needs to be descaled. After the user finishes using hot water, the water purifier automatically descales according to the descaling control information, thereby improving the efficiency and intelligence of descaling the water purifier, ensuring user experience, reducing labor costs, and solving the problem of how to improve the efficiency of descaling the water purifier.
