Description

Technical Field

[0001] The present invention relates to the field of control technologies, and in particular, to a water treatment device, a control method and device thereof, and a readable storage medium. Background Art

[0002] Existing instant hot water dispensers are powered by the mains electricity. Specifically, the heating barrel in the instant hot water dispenser operates under the mains electricity supply to complete the heating of the liquid to be heated.

[0003] Those skilled in the art have found that existing instant hot water dispensers have the following drawbacks:

[0004] The outlet water temperature of existing instant hot water dispensers fluctuates greatly. When the set temperature approaches the boiling point, steam spraying is very likely to occur. Due to the existence of steam spraying, there are certain safety hazards in the instant hot water dispenser. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art or related technologies.

[0006] To this end, in the first aspect of the present invention, a control method for a water treatment device is provided.

[0007] In the second aspect of the present invention, a control device for a water treatment device is provided.

[0008] In the third aspect of the present invention, a readable storage medium is provided.

[0009] In the fourth aspect of the present invention, a water treatment device is provided.

[0010] In view of this, according to the first aspect of the present invention, a control method for a water treatment device is provided, including: in response to a water intake input, periodically obtaining the input voltage value of the water treatment device; determining the fluctuation value of the input voltage value; and controlling the water outlet flow rate of the water treatment device according to the comparison result between the fluctuation value and a preset fluctuation threshold.

[0011] The technical solution of the present application proposes a control method for a water treatment device. The water treatment device applying this control method can reduce the influence of the input voltage fluctuation on the outlet water temperature, so that the outlet water temperature of the water treatment device tends to be stable.

[0012] Since the outlet water temperature of the water treatment device tends to be stable, therefore, when the set temperature approaches the boiling point of the liquid, the probability of steam spraying of the liquid output by the water treatment device is reduced, thereby eliminating the safety hazards in the existing water treatment device, such as reducing the occurrence of steam burns, and further improving the use safety of the water treatment device.

[0013] In addition, when using a water treatment device to cook or brew food ingredients, since the outlet water temperature of the water treatment device tends to be stable, the probability of destroying the nutrients in the food ingredients due to excessive fluctuations in the outlet water temperature of the water treatment device, such as too high outlet water temperature, is reduced.

[0014] Specifically, the reason for the fluctuation of the outlet water temperature is that there are fluctuations in the voltage of the commercial power supply, and the real-time power of the heating barrel will also change. Therefore, when the outlet water flow rate of the water treatment device remains fixed, the outlet water temperature will continuously fluctuate. Furthermore, when the set temperature tends to reach the boiling point, the phenomenon of steam spraying is likely to occur, and at the same time, there will also be problems of potential safety hazards.

[0015] In the technical solution of the present application, in response to receiving a water intake input, a water intake output will be responded to, such as controlling the operation of the pump body of the water treatment device to achieve the supply of liquid.

[0016] To overcome the above problems, the input voltage value is also obtained, and the fluctuation situation of the power supply voltage of the water treatment device is determined according to the obtained input voltage value, that is, the fluctuation value mentioned above. By calculating the fluctuation value, the fluctuation value is used to characterize the fluctuation situation of the commercial power supply. By comparing the fluctuation value with a preset fluctuation threshold, the magnitude of the current commercial power supply fluctuation is determined, so as to control the outlet water flow rate according to the comparison result. By controlling the outlet water flow rate, the influence of the input voltage fluctuation on the outlet water temperature is suppressed, so that the outlet water temperature of the water treatment device tends to be stable.

[0017] In any of the above technical solutions, the input voltage value is also the power supply voltage of the water treatment device, and it can be obtained by using the power supply module connecting the water treatment device to the commercial power supply. Specifically, the power supply module can be a voltage detection device.

[0018] In any of the above technical solutions, by limiting that the input voltage value is obtained periodically, the influence of the uneven sampling interval of the input voltage value on the fluctuation value is eliminated, thereby improving the control accuracy of the outlet water flow rate.

[0019] In any of the above technical solutions, the fluctuation value can be understood as the difference between the current sampling value of the input voltage value and the previous sampling value of the input voltage value.

[0020] In any of the above technical solutions, the value of the preset fluctuation threshold can be set according to the actual parameters of the water treatment device.

[0021] In one of the technical solutions, the value of the preset fluctuation threshold is negatively correlated with the volume of the heating barrel of the water treatment device. For example, when the volume of the heating barrel of the water treatment device is large, the value of the preset fluctuation threshold is small; on the contrary, when the volume of the heating barrel of the water treatment device is small, the value of the preset fluctuation threshold is large.

[0022] In any of the above technical solutions, controlling the water output flow rate of the water treatment device according to the comparison result between the fluctuation value and the preset fluctuation threshold can be understood as determining the comparison result between the fluctuation value and the preset fluctuation threshold, and controlling the water output flow rate according to the control scheme corresponding to the comparison result.

[0023] In addition, the control method of the water treatment device proposed in this application also has the following additional technical features.

[0024] In the above technical solution, based on the fluctuation value being less than or equal to the preset fluctuation threshold, at the current detection moment, obtain the first input voltage value of the water treatment device and the calculated value of the water output flow rate; obtain the second input voltage value of the water treatment device at the previous detection moment; determine the water output flow rate according to the first input voltage value, the second input voltage value, and the calculated value.

[0025] In this technical solution, when the fluctuation value is not higher than the preset fluctuation value, it is considered that the fluctuation of the current input voltage value is not very large. At this time, the water output flow rate can be controlled based on the law of conservation of energy. Controlling the water output flow rate using the law of conservation of energy can make the fluctuation of the water output temperature smaller and reduce the excessive adjustment range of the water output temperature, which affects the user's use.

[0026] In one of the technical solutions, it can be understood that the first sampling value is the sampling value of the input voltage value at the current detection moment, and the calculated value is the water output flow rate obtained by processing the current water output temperature and the set temperature value using the temperature control logic.

[0027] In one of the technical solutions, the previous detection moment is a statement based on the current detection moment. Based on the above, the input voltage value is collected periodically. Periodicity can be understood as collecting the input voltage value once every fixed time interval. Based on this, the previous detection moment can be understood as the moment at a fixed time before the current detection moment.

[0028] In any of the above technical solutions, the fixed time interval can be set according to the actual use scenario of the water treatment device, and its value is not limited here.

[0029] In any of the above technical solutions, determining the water output flow rate according to the first input voltage value, the second input voltage value, and the calculated value includes: determining the first squared value corresponding to the first input voltage value and the second squared value corresponding to the second input voltage value; taking the product of the ratio of the first squared value to the second squared value and the calculated value as the water output flow rate.

[0030] In any of the above technical solutions, based on the fluctuation value being greater than the preset fluctuation threshold, obtain the first input voltage value of the water treatment device at the current detection moment; obtain the rated input voltage of the water treatment device and the set water output flow rate of the water treatment device under the rated input voltage; determine the water output flow rate according to the first input voltage value, the rated input voltage, and the set water output flow rate.

[0031] In this technical solution, when the fluctuation value exceeds the preset fluctuation threshold, it is considered that the fluctuation of the input voltage is large. If the water output flow rate is still controlled based on energy conservation, the determined water output flow rate is very likely to cause the water output temperature to exceed the set temperature value by a large margin, resulting in steam spraying from the water treatment device.

[0032] To avoid the above situation, the technical solution of this application adopts pure feedforward control to reduce the probability of the water output temperature exceeding the set temperature value by a large margin, making the water output temperature of the water treatment device tend to be stable.

[0033] In one of the technical solutions, it can be understood that the rated input voltage can be obtained through the nameplate of the water treatment device.

[0034] In one of the technical solutions, the set water output flow rate can be understood as the theoretical water output flow rate of the water treatment device when the input voltage value of the water treatment device is the rated input voltage under the same working conditions.

[0035] In one of the technical solutions, the same working conditions can be understood as having the same inlet water temperature and outlet water temperature, that is, having the same temperature rise.

[0036] In any of the above technical solutions, determining the water output flow rate according to the first input voltage value, the rated input voltage, and the set water output flow rate includes: determining the first square value corresponding to the first input voltage value and the third square value corresponding to the rated input voltage; taking the product of the ratio of the first square value to the third square value and the set water output flow rate as the water output flow rate.

[0037] In this technical solution, the specific scheme of the water output flow rate is defined. The above scheme is adopted to determine the water output flow rate to reduce the probability of the water output temperature exceeding the set temperature value by a large margin, making the water output temperature of the water treatment device tend to be stable.

[0038] In any of the above technical solutions, the third square value is the square value of the rated input voltage.

[0039] In any of the above technical solutions, it further includes: obtaining the set power of the water treatment device; determining the set water output flow rate according to the set power.

[0040] In this technical solution, a solution for determining the set water output flow rate is defined. In this technical solution, the set water output flow rate is determined according to the set power, that is, according to the actual setting of the water treatment device. Therefore, the determined set water output flow rate matches the actual working conditions of the water treatment device, so that the obtained water output flow rate can overcome the probability of the water output temperature exceeding the set temperature value by a large margin, making the water output temperature of the water treatment device tend to be stable.

[0041] In any of the above technical solutions, it further includes: determining the duration for controlling the water output flow rate of the water treatment device according to the comparison result between the fluctuation value and the preset fluctuation threshold; based on the duration being greater than the preset duration, inputting water intake into the water output.

[0042] In this technical solution, by limiting that water intake is input into the water output only when the duration exceeds the preset duration, so that the water treatment device can have enough time to control the water output flow rate, so as to ensure that after the preset duration, the water output temperature of the water treatment device tends to be stable.

[0043] In any of the above technical solutions, the value of the preset fluctuation threshold is between 6 volts and 10 volts.

[0044] In this technical solution, the selected value of the preset fluctuation threshold can be 7 volts, 8 volts or 9 volts, and its specific value can be set according to the actual use scenario, which will not be elaborated here.

[0045] According to the second aspect of the present invention, the present invention provides a control device for a water treatment device, including: an acquisition unit for periodically acquiring the input voltage value of the water treatment device in response to water intake input; a determination unit for determining the fluctuation value of the input voltage value; a control unit for controlling the water output flow rate of the water treatment device according to the comparison result between the fluctuation value and the preset fluctuation threshold.

[0046] The technical solution of the present application proposes a control device for a water treatment device. The water treatment device applying this control device can reduce the influence of the fluctuation of the input voltage on the water output temperature, making the water output temperature of the water treatment device tend to be stable.

[0047] Since the water output temperature of the water treatment device tends to be stable, therefore, when the set temperature tends to the boiling point of the liquid, the probability of the liquid output by the water treatment device spraying steam is reduced, thereby eliminating potential safety hazards in the existing water treatment device, such as reducing the occurrence of steam burns, and further improving the use safety of the water treatment device.

[0048] In addition, when using the water treatment device to cook or brew food materials, since the water output temperature of the water treatment device tends to be stable, therefore, the probability of the water output temperature of the water treatment device fluctuating too much, such as the water output temperature being too high and damaging the nutritional components in the food materials, is reduced.

[0049] Specifically, the reason for the fluctuation of the outlet water temperature is that there are fluctuations in the voltage of the commercial power supply, and the real-time power of the heating barrel will also change. Therefore, when the outlet water flow rate of the water treatment device remains fixed, the outlet water temperature will fluctuate continuously. Furthermore, when the set temperature approaches the boiling point, the phenomenon of steam spraying is likely to occur, and at the same time, there will also be potential safety hazards.

[0050] In the technical solution of the present application, upon receiving the water intake input, a response will be made to the water intake output, such as controlling the operation of the pump body of the water treatment device to achieve the supply of liquid.

[0051] To overcome the above problems, the input voltage value is also obtained, and based on the obtained input voltage value, the fluctuation situation of the power supply voltage of the water treatment device is determined, that is, the fluctuation value mentioned above. By calculating the fluctuation value, the fluctuation value is used to characterize the fluctuation of the commercial power supply. By comparing this fluctuation value with a preset fluctuation threshold, the magnitude of the current commercial power supply fluctuation is determined, so as to control the outlet water flow rate according to the comparison result. By controlling the outlet water flow rate, the influence of the input voltage fluctuation on the outlet water temperature is suppressed, making the outlet water temperature of the water treatment device tend to be stable.

[0052] In any of the above technical solutions, the input voltage value, that is, the power supply voltage of the water treatment device, can be obtained by using the power supply module connecting the water treatment device to the commercial power supply. Specifically, the power supply module can be a voltage detection device.

[0053] In any of the above technical solutions, by limiting that the input voltage value is obtained periodically, the influence of the uneven sampling interval of the input voltage value on the fluctuation value is eliminated, thereby improving the control accuracy of the outlet water flow rate.

[0054] In any of the above technical solutions, the fluctuation value can be understood as the difference between the current sampling value of the input voltage value and the previous sampling value of the input voltage value.

[0055] In any of the above technical solutions, the value of the preset fluctuation threshold can be set according to the actual parameters of the water treatment device.

[0056] In one of the technical solutions, the value of the preset fluctuation threshold is negatively correlated with the volume of the heating barrel of the water treatment device. For example, when the volume of the heating barrel of the water treatment device is large, the value of the preset fluctuation threshold is small; conversely, when the volume of the heating barrel of the water treatment device is small, the value of the preset fluctuation threshold is large.

[0057] In any of the above technical solutions, controlling the water output flow rate of the water treatment device according to the comparison result between the fluctuation value and the preset fluctuation threshold can be understood as determining the comparison result between the fluctuation value and the preset fluctuation threshold, and controlling the water output flow rate according to the control scheme corresponding to the comparison result.

[0058] In one of the technical solutions, the control unit is specifically configured to: based on the fluctuation value being less than or equal to the preset fluctuation threshold, obtain the first input voltage value of the water treatment device and the calculated value of the water output flow rate at the current detection moment; obtain the second input voltage value of the water treatment device at the previous detection moment; and determine the water output flow rate according to the first input voltage value, the second input voltage value, and the calculated value.

[0059] In this technical solution, when the fluctuation value is not higher than the preset fluctuation value, it is considered that the fluctuation of the current input voltage value is not very large. At this time, the water output flow rate can be controlled based on the law of conservation of energy. Controlling the water output flow rate by using the law of conservation of energy can make the fluctuation of the water output temperature smaller and reduce the excessive adjustment range of the water output temperature, which affects the user's use.

[0060] In one of the technical solutions, it can be understood that the first sampling value is the sampling value of the input voltage value at the current detection moment, and the calculated value is the water output flow rate obtained by processing the current water output temperature and the set temperature value using the temperature control logic.

[0061] In one of the technical solutions, the previous detection moment is a statement based on the current detection moment. Based on the above, the input voltage value is collected periodically. Periodicity can be understood as collecting the input voltage value once every fixed duration. Based on this, the previous detection moment can be understood as the moment at a fixed duration before the current detection moment.

[0062] In any of the above technical solutions, the fixed duration can be set according to the actual usage scenario of the water treatment device, and its value is not limited here.

[0063] In any of the above technical solutions, the control unit is specifically configured to: determine the first square value corresponding to the first input voltage value and the second square value corresponding to the second input voltage value; and use the product of the ratio of the first square value to the second square value and the calculated value as the water output flow rate.

[0064] In any of the above technical solutions, the control unit is specifically configured to: based on the fluctuation value being greater than the preset fluctuation threshold, obtain the first input voltage value of the water treatment device at the current detection moment; obtain the rated input voltage of the water treatment device and the set water output flow rate of the water treatment device under the rated input voltage; and determine the water output flow rate according to the first input voltage value, the rated input voltage, and the set water output flow rate.

[0065] In this technical solution, when the fluctuation value exceeds the preset fluctuation threshold, it is considered that the fluctuation of the input voltage is large. If the water output flow is still controlled based on energy conservation, the determined water output flow is very likely to cause the water output temperature to exceed the set temperature value by a large margin, resulting in steam spraying in the water treatment device.

[0066] To avoid the above situation, the technical solution of this application adopts pure feedforward control to reduce the occurrence probability of the situation where the water output temperature exceeds the set temperature value by a large margin, making the water output temperature of the water treatment device tend to be stable.

[0097] In order to more clearly understand the above aspects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0098] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0099] Embodiment 1

[0100] As Figure 1As shown, according to one embodiment of the present invention, the present invention provides a control method for a water treatment device, comprising:

[0101] Step 102, in response to water intake input, periodically acquiring an input voltage value of a water treatment device;

[0102] Step 104, determining the fluctuation value of the input voltage value;

[0103] Step 106, controlling the water outlet flow of the water treatment device according to the comparison result between the fluctuation value and the preset fluctuation threshold value.

[0104] The embodiment of the present application proposes a control method for a water treatment device. The water treatment device using the control method can reduce the impact of input voltage fluctuations on outlet water temperature, so that the outlet water temperature of the water treatment device tends to be stable.

[0105] Since the outlet water temperature of the water treatment device tends to be stable, when the set temperature tends to the boiling point of the liquid, the probability of steam spraying from the liquid output by the water treatment device is reduced, thereby eliminating the safety hazards in the existing water treatment device, such as reducing the occurrence of steam scalds, thereby improving the safety of the water treatment device.

[0106] In addition, when using a water treatment device to cook or brew food, since the outlet water temperature of the water treatment device tends to be stable, the probability of destroying the nutrients in the food due to excessive fluctuations in the outlet water temperature of the water treatment device, such as excessive outlet water temperature, is reduced.

[0107] Specifically, the reason for the fluctuation in the outlet water temperature is the fluctuation in the voltage of the AC power, and the real-time power of the heating barrel will also change. Therefore, when the outlet water flow rate of the water treatment device is fixed, the outlet water temperature will continue to fluctuate, and when the set temperature approaches the boiling point, steam spraying is very likely to occur. At the same time, there will also be safety hazards.

[0108] When receiving a water intake input, the embodiment of the present application will respond to the water intake output, such as controlling the operation of a pump body of a water treatment device to achieve liquid supply.

[0109] In order to overcome the above problems, the input voltage value is also obtained, and the fluctuation of the power supply voltage of the water treatment device is determined according to the obtained input voltage value, that is, the fluctuation value mentioned above. The fluctuation value is calculated and used to characterize the fluctuation of the mains power supply. The fluctuation value is compared with the preset fluctuation threshold value to determine the fluctuation size of the current mains power supply, so as to control the water flow rate according to the comparison result. By controlling the water flow rate, the influence of the fluctuation of the input voltage on the water outlet temperature is suppressed, so that the water outlet temperature of the water treatment device tends to be stable.

[0110] In any of the above embodiments, the input voltage value, which is also the power supply voltage of the water treatment device, can be obtained by using the power supply module that connects the water treatment device to the mains power. Specifically, the power supply module can be a voltage detection device.

[0111] In any of the above embodiments, by defining that the input voltage value is obtained periodically, the influence of the uneven sampling interval of the input voltage value on the fluctuation value can be eliminated, thereby improving the control accuracy of the water output flow rate.

[0112] In any of the above embodiments, the fluctuation value can be understood as the difference between the current sampling value of the input voltage value and the previous sampling value of the input voltage value.

[0113] In any of the above embodiments, the value of the preset fluctuation threshold can be set according to the actual parameters of the water treatment device.

[0114] In one of the embodiments, the value of the preset fluctuation threshold is negatively correlated with the volume of the heating bucket of the water treatment device. For example, when the volume of the heating bucket of the water treatment device is large, the value of the preset fluctuation threshold is relatively small; conversely, when the volume of the heating bucket of the water treatment device is small, the value of the preset fluctuation threshold is relatively large.

[0115] In any of the above embodiments, controlling the water output flow rate of the water treatment device according to the comparison result between the fluctuation value and the preset fluctuation threshold can be understood as determining the comparison result between the fluctuation value and the preset fluctuation threshold, and controlling the water output flow rate according to the control scheme corresponding to the comparison result.

[0116] In any of the above embodiments, the water intake input can be understood as triggering the water output button of the water treatment device.

[0117] Embodiment 2

[0118] In one of the embodiments, as Figure 2 shown, controlling the water output flow rate of the water treatment device according to the comparison result between the fluctuation value and the preset fluctuation threshold includes:

[0119] Step 202, based on the fluctuation value being less than or equal to the preset fluctuation threshold, obtain the first input voltage value of the water treatment device and the calculated value of the water output flow rate at the current detection moment;

[0120] Step 204, obtain the second input voltage value of the water treatment device at the previous detection moment;

[0121] Step 206, determine the water output flow rate according to the first input voltage value, the second input voltage value, and the calculated value.

[0122] In this embodiment, when the fluctuation value is not higher than the preset fluctuation value, it is considered that the fluctuation of the current input voltage value is not significant. At this time, the water outlet flow rate can be controlled based on the law of conservation of energy. Controlling the water outlet flow rate based on the law of conservation of energy can make the fluctuation of the water outlet temperature smaller and reduce the excessive adjustment range of the water outlet temperature, which affects the user experience.

[0123] In one of the embodiments, as Figure 5 shown, it can be understood that the first sampling value is the sampling value of the input voltage value at the current detection moment, and the calculated value is the water outlet flow rate obtained by processing the current water outlet temperature and the set temperature value using the temperature control logic.

[0124] In one of the embodiments, the previous detection moment is a statement based on the current detection moment. Based on the above, the input voltage value is collected periodically. Periodicity can be understood as collecting the input voltage value once every fixed time interval. Based on this, the previous detection moment can be understood as the moment at a fixed time interval before the current detection moment.

[0185] In any of the above embodiments, the value of the preset fluctuation threshold is between 6 volts and 10 volts.

[0186] In this embodiment, the selected value of the preset fluctuation threshold can be 7 volts, 8 volts or 9 volts, and its specific value can be set according to the actual usage scenario and will not be elaborated here.

[0187] Embodiment Seven

[0188] In one of the embodiments, such as Figure 4As shown in the figure, the present invention provides a control device 400 for a water treatment device, including: an acquisition unit 402, configured to periodically acquire the input voltage value of the water treatment device in response to a water intake input; a determination unit 404, configured to determine the fluctuation value of the input voltage value; and a control unit 406, configured to control the water output flow of the water treatment device according to the comparison result between the fluctuation value and a preset fluctuation threshold value.

[0189] An embodiment of the present application proposes a control device 400 for a water treatment device. The water treatment device applying this control device can reduce the influence of the fluctuation of the input voltage on the water outlet temperature, making the water outlet temperature of the water treatment device tend to be stable.

[0190] Since the water outlet temperature of the water treatment device tends to be stable, therefore, when the set temperature tends to the boiling point of the liquid, the probability of steam spraying in the liquid output by the water treatment device is reduced, thereby eliminating potential safety hazards in the existing water treatment device, such as reducing the occurrence of steam burns, and further improving the use safety of the water treatment device.

[0191] In addition, when using the water treatment device to cook or brew food materials, since the water outlet temperature of the water treatment device tends to be stable, the probability of destroying the nutrients in the food materials due to excessive fluctuation of the water outlet temperature of the water treatment device, such as too high water outlet temperature, is reduced.

[0192] Specifically, the reason for the fluctuation of the water outlet temperature is that there is a fluctuation in the voltage of the mains power supply, and the real-time power of the heating barrel will also change. Therefore, when the water output flow of the water treatment device remains unchanged, the water outlet temperature will fluctuate continuously. Furthermore, when the set temperature tends to the boiling point, the phenomenon of steam spraying is very likely to occur, and at the same time, there will also be a problem of potential safety hazards.

[0193] In the embodiment of the present application, when receiving a water intake input, it will respond to the water intake output, such as controlling the operation of the pump body of the water treatment device to achieve the supply of liquid.

[0194] To overcome the above problems, the input voltage value is also acquired, and the fluctuation condition of the power supply voltage of the water treatment device is determined according to the acquired input voltage value, that is, the fluctuation value mentioned above. By calculating the fluctuation value, the fluctuation value is used to characterize the fluctuation condition of the mains power supply. By comparing the fluctuation value with a preset fluctuation threshold value, the current fluctuation size of the mains power supply can be determined, and thus the water output flow is controlled according to the comparison result. By controlling the water output flow, the influence of the fluctuation of the input voltage on the water outlet temperature is suppressed, making the water outlet temperature of the water treatment device tend to be stable.

[0195] In any of the above embodiments, the input voltage value, which is also the power supply voltage of the water treatment device, can be obtained by using the power supply module that connects the water treatment device to the mains power. Specifically, the power supply module can be a voltage detection device.

[0196] In any of the above embodiments, by defining that the input voltage value is obtained periodically, the influence of the uneven sampling interval of the input voltage value on the fluctuation value is eliminated, thereby improving the control accuracy of the water output flow rate.

[0197] In any of the above embodiments, the fluctuation value can be understood as the difference between the current sampling value of the input voltage value and the previous sampling value of the input voltage value.

[0198] In any of the above embodiments, the value of the preset fluctuation threshold can be set according to the actual parameters of the water treatment device.

[0199] In one of the embodiments, the value of the preset fluctuation threshold is negatively correlated with the volume of the heating barrel of the water treatment device. For example, when the volume of the heating barrel of the water treatment device is large, the value of the preset fluctuation threshold is relatively small; conversely, when the volume of the heating barrel of the water treatment device is small, the value of the preset fluctuation threshold is relatively large.

[0200] In any of the above embodiments, controlling the water output flow rate of the water treatment device according to the comparison result between the fluctuation value and the preset fluctuation threshold can be understood as determining the comparison result between the fluctuation value and the preset fluctuation threshold, and controlling the water output flow rate according to the control scheme corresponding to the comparison result.

[0201] In one of the embodiments, the control unit 406 is specifically configured to: based on the fluctuation value being less than or equal to the preset fluctuation threshold, obtain the first input voltage value of the water treatment device and the calculated value of the water output flow rate at the current detection moment; obtain the second input voltage value of the water treatment device at the previous detection moment; and determine the water output flow rate according to the first input voltage value, the second input voltage value, and the calculated value.

[0202] In this embodiment, when the fluctuation value is not higher than the preset fluctuation value, it is considered that the fluctuation of the current input voltage value is not large. At this time, the water output flow rate can be controlled based on the law of conservation of energy. Controlling the water output flow rate by using the law of conservation of energy can make the fluctuation of the water output temperature smaller and reduce the excessive adjustment range of the water output temperature, which affects the user's use.

[0203] In one of the embodiments, it can be understood that the first sampling value is the sampling value of the input voltage value at the current detection moment, and the calculated value is the water output flow rate obtained by processing the current water output temperature and the set temperature value using the temperature control logic.

[0204] In one embodiment, the previous detection moment is a statement based on the current detection moment. Based on the above, it can be known that the input voltage value is collected periodically. Periodicity can be understood as collecting the input voltage value once every fixed duration. Based on this, the previous detection moment can be understood as the moment at a fixed duration before the current detection moment.

[0205] In any of the above embodiments, the fixed duration can be set according to the actual usage scenario of the water treatment device, and its value is not limited here.

[0206] In any of the above embodiments, the control unit 406 is specifically configured to: determine the first squared value corresponding to the first input voltage value and the second squared value corresponding to the second input voltage value; use the product of the ratio of the first squared value to the second squared value and the calculated value as the water outlet flow rate.

[0207] In this embodiment, the specific scheme for the water outlet flow rate is defined. Based on the above, when the fluctuation value is not higher than the preset fluctuation value, the water outlet flow rate is controlled based on the law of conservation of energy. Among them, the formula followed by the law of conservation of energy is:

[0208]

[0209] Among them, c is the specific heat capacity of water, ΔT is the difference between the water outlet temperature and the water inlet temperature, that is, the temperature rise, P is the heating power, δ is the thermal efficiency, which is approximately 1 here, R is the resistance of the heating barrel, and F is the water outlet flow rate.

[0210] Assume the second input voltage value U formal , the first input voltage value U minow , when the fluctuation value is not higher than the preset fluctuation value, the fluctuation value is expressed as ΔU mi , in the presence of the above-mentioned fluctuation interference, if it is desired that ΔT remains unchanged, the water outlet flow rate after the input voltage fluctuation is F minow , at this time, the water outlet flow rate F minow can be determined by the following formula:

[0211]

[0212] Among them, F now is the calculated value in the above text.

[0213] In any of the above embodiments, the first squared value is the square value of the first input voltage value.

[0214] In any of the above embodiments, the second squared value is the square value of the second input voltage value.

[0216] In this embodiment, when the fluctuation value exceeds the preset fluctuation threshold, it is considered that the fluctuation of the input voltage is large. If the water output flow rate is still controlled based on energy conservation, the determined water output flow rate is very likely to cause the water output temperature to exceed the set temperature value by a large margin, resulting in steam spraying of the water treatment device.

[0217] To avoid the above situation, the embodiment of the present application adopts pure feedforward control to reduce the occurrence probability of the situation where the water output temperature exceeds the set temperature value by a large margin, making the water output temperature of the water treatment device tend to be stable.

In this embodiment, the set water output flow rate is determined according to the set power, that is, according to the actual setting of the water treatment device. Therefore, the determined set water output flow rate matches the actual working conditions of the water treatment device, so as to determine that the water output flow rate obtained can overcome the probability of the water output temperature exceeding the set temperature value by a large margin, making the water output temperature of the water treatment device tend to be stable.
