[0051] The present disclosure is further described below by way of examples, but the present disclosure is not limited to the scope of the examples.

[0052] Prefixes such as "first" and "second" are used in the embodiments of the present disclosure only to distinguish different description objects, and have no limiting effect on the position, order, priority, quantity or content of the described objects. The use of prefixes such as ordinal numbers to distinguish description objects in the embodiments of the present disclosure does not constitute a limitation on the described objects. For the statement of the described objects, please refer to the description in the context of the claims or embodiments, and no unnecessary limitation should be constituted due to the use of such prefixes. In addition, in the description of the present embodiment, unless otherwise specified, the meaning of "plurality" is two or more.

[0053] Example 1

[0054] The heat exchange control method of the water purification equipment of this embodiment is applied in the water purification equipment, which includes a refrigeration module and different types of pipelines. The refrigeration module includes a heat exchange water tank and a condenser that dissipates heat through the heat exchange water tank. Different types of pipelines are connected to the heat exchange water tank.

[0055] Specifically, Figure 1 As shown, the water purification equipment includes a water production part, a refrigeration part and a heat exchange part; wherein the water production part includes a solenoid valve 1, a pretreatment filter element, a booster pump, a reverse osmosis filter element, a solenoid valve 2, and a water storage device which are sequentially connected to the first pipeline, and finally provide cold water or ice cubes to the rear end; the water production part also includes a solenoid valve 1, a pretreatment filter element, a booster pump, a reverse osmosis filter element, and a solenoid valve 3 which are sequentially connected to the second pipeline, and finally connected to the normal temperature water end to provide normal temperature water, that is, corresponding to the water production function, directly discharge water or supply water to the refrigeration part;

[0056] The refrigeration part includes an evaporator, a compressor, a heat exchange water tank, a condenser, a temperature sensor, etc. The condenser and the heat exchange water tank are integrated together and connected to the evaporator and the compressor respectively; the refrigeration part also includes a third pipeline connected to the outlet of the preset processor filter element at one end and connected to the heat exchange water tank at the other end, and an adjustable water valve is arranged on the pipeline; that is, it corresponds to the refrigeration function;

[0057] Among them, Figure 2 As shown, the condenser 10 and the heat exchange water tank 20 are integrated together, and the condenser 10 is provided with a water inlet 100, a water outlet 200, a first connection end 300 and a second connection end 400; wherein the water inlet 100 is connected to a wastewater waterway, a wastewater solenoid valve is provided on the wastewater waterway, the water outlet 200 is a wastewater discharge port, the first connection end 300 is connected to the compressor, the second connection end 400 is connected to the evaporator, and a temperature sensor (or temperature sensing probe) for collecting temperature is provided on the second connection end 400;

[0058] The heat exchange part includes a wastewater waterway, which is connected to the heat exchange water tank and discharges the wastewater flowing through the heat exchange water tank through the wastewater outlet. This part mainly uses the wastewater generated by the water production part for heat exchange in the refrigeration part.

[0059] When working in a compression refrigeration system, heat is dissipated through the condenser. The compressor discharges high-temperature and high-pressure gas, which is dissipated through the condenser. The normal temperature at the end of the condenser is generally slightly higher than the ambient temperature. If the temperature at the end of the condenser is too high, it means that the heat dissipation is insufficient. When using condenser water cooling to dissipate heat, the flow rate is too large, resulting in water waste. If the water volume is too small, the heat dissipation is poor, affecting the refrigeration effect. The actual water cooling flow rate is related to the water temperature, ambient temperature, and the water pressure of the user's home. Therefore, it is necessary to reasonably adjust the water pressure to make the water cooling flow rate reach the optimal value to ensure that the temperature at the end of the condenser is within the required range. Specifically:

[0060] like Figure 3 As shown, the heat exchange control method of the water purification equipment of this embodiment includes:

[0061] S101, obtaining the current working mode of the water purification device;

[0062] Among them, the current working mode includes an ice-making only working mode, a water-making and ice-making working mode at the same time, and the like.

[0063] S102, controlling the target pipeline matching the current working mode to start working, so as to allow the water in the target pipeline to flow into the heat exchange water tank;

[0064] Specifically, when the current working mode is a cooling-only working mode, the target pipeline is a coarse filtered water pipeline in the water purification device;

[0065] Among them, an adjustable water valve is provided on the coarse filtered water waterway, and the two ends of the coarse filtered water waterway are respectively connected with the outlet of the pre-treatment filter element in the water purification equipment and the heat exchange water tank, and the flow regulating valve is an adjustable water valve;

[0066] When the current working mode is a working mode of making water and ice at the same time, the target pipeline is a waste water pipeline and a coarse filtered water pipeline in the water purification equipment;

[0067] Among them, a wastewater solenoid valve is provided on the wastewater waterway, and the two ends of the wastewater waterway are respectively connected to the outlet of the reverse osmosis filter element and the heat exchange water tank in the water purification equipment; the two ends of the coarse filtered water waterway are respectively connected to the outlet of the pretreatment filter element and the heat exchange water tank in the water purification equipment; the flow regulating valve is an adjustable water valve.

[0068] S103, obtaining the actual ambient temperature of the environment where the water purification equipment is located;

[0069] Among them, it can be obtained by collecting the ambient temperature sensor. The ambient temperature sensor can be integrated in the water purification equipment, or can be set outside the water purification equipment, as long as the corresponding collected data can be sent to the water purification equipment.

[0070] S104, based on the actual ambient temperature and the preset determination strategy, determine the target input voltage value of the flow control valve in the target pipeline, and adjust the amount of water flowing through the flow control valve so that the temperature at the end of the condenser meets the preset temperature range.

[0071] Among them, there is a mapping relationship between the target input voltage value of the flow control valve and the amount of water flowing through it. By accurately controlling the input target input voltage value, the amount of water flowing through it can also be accurately controlled, thereby achieving effective control of the optimal water exchange water volume.

[0072] In this embodiment, by pre-configuring the heat exchange control scheme of the water purification equipment, when the water purification equipment is in an ice-making only working mode, a water-making and ice-making working mode, etc., the water flow in the matching pipeline is driven to flow through the heat exchange water tank to dissipate the heat of the condenser, thereby avoiding the high noise and poor heat dissipation effect caused by the existing use of fans on the condenser, and the condenser can be dissipated in a timely and effective manner; at the same time, the target input voltage value of the flow control valve in the target pipeline can be adaptively adjusted according to the actual ambient temperature, so as to achieve accurate and timely regulation of the amount of water flowing through the flow control valve, achieve the optimal water exchange water volume, and ensure that the temperature value at the end of the condenser can always dynamically and timely meet the heat dissipation requirements; in addition, it can also be adjusted in time with the changes in environmental parameters to ensure that the temperature value at the end of the condenser can always dynamically and timely meet the heat dissipation requirements regardless of different ambient temperatures such as summer and winter, thereby further improving the refrigeration performance of the water purification equipment and the overall product performance.

[0073] Example 2

[0074] The heat exchange control method of the water purification equipment of this embodiment is a further improvement of the embodiment 1, specifically:

[0075] In an implementable solution, when the current working mode is a cooling-only working mode, the adjustable water valve is controlled to open, and the step of obtaining the current working mode of the water purification device is performed;

[0076] When the current working mode is a working mode of making water and ice at the same time, before step S101, the method further includes:

[0077] In response to the current temperature value at the end of the condenser being less than a preset temperature value, determining that the adjustable water valve remains in a closed state;

[0078] In response to the current temperature value at the end of the condenser being greater than or equal to the preset temperature value, the adjustable water valve is controlled to open, and step S101 is executed;

[0079] The preset temperature value is determined based on the actual ambient temperature.

[0080] At this time, in the cooling-only working mode, the cooling module works, the adjustable water valve is opened, and the water flow of the adjustable water valve is adjusted according to the preset determination strategy;

[0081] In the working mode of making water and ice at the same time, it is necessary to first confirm whether the adjustable water valve needs to be opened. If necessary, the adjustable water valve is opened and the water flow of the adjustable water valve is adjusted according to the preset strategy; if not, the adjustable water valve is kept in the closed state.

[0082] In the present disclosure, under different working modes, the corresponding water flow control schemes are also different, so as to ensure that the water flow of the adjustable water valve in each working mode can be efficiently and accurately regulated and controlled, thereby ensuring that a good heat dissipation control effect can be achieved regardless of the working mode.

[0083] In one feasible solution, Figure 4 As shown, step S104 includes:

[0084] S1041, obtaining the current temperature value of the condenser terminal and the current actual voltage value corresponding to the adjustable water valve at the first collection time after the adjustable water valve is opened, and obtaining the previous historical voltage value corresponding to the adjustable water valve when the temperature of the condenser terminal reaches the preset temperature last time, and calculating using a preset determination strategy to obtain a target input voltage value corresponding to the adjustable water valve when the temperature of the condenser terminal reaches the preset temperature;

[0085] Specifically, the calculation formula corresponding to the preset determination strategy is:

[0086] U(t) = Kp*e(t) + Ki*Σe(t) + Kd*( e(t) - e(t-1))

[0087] Among them, t represents the current refrigeration process, t-1 represents the previous refrigeration process, U(t) represents the target input voltage value of the adjustable water valve in the current refrigeration process, e(t) represents the current voltage deviation value between the previous historical voltage value and the current actual voltage value in the current refrigeration process, the previous historical voltage value represents the input voltage value corresponding to the adjustable water valve when the temperature at the end of the previous condenser reaches the preset temperature (such as T = 20°C), and the current actual voltage value represents the input voltage value corresponding to the adjustable water valve when the current temperature value (T = T1) at the end of the condenser; e(t-1) represents the voltage deviation value between the historical voltage value at the t-2th time and the current actual voltage value at the t-1th time in the previous refrigeration process; Kp, Ki, and Kd are coefficients respectively.

[0088] Based on the above calculation method, the optimal input voltage value U(t) of the adjustable water valve under different ambient temperatures can be obtained. That is, according to different ambient temperatures, the adjustable water valve is controlled by using the matching optimal input voltage value U(t), which can ensure that the temperature at the end of the condenser is within the required temperature range, thereby achieving efficient and effective heat dissipation.

[0089] S1042. Use the target input voltage value to control the water flow through the adjustable water valve, and dissipate the heat at the end of the condenser through the water flow in the heat exchange water tank, so that the current temperature value of the end of the condenser is less than the preset temperature value.

[0090] In the present disclosure, based on the current temperature value of the condenser end and the current actual voltage value corresponding to the adjustable water valve, and the target input voltage value corresponding to the adjustable water valve when the temperature of the condenser end recorded last time reaches the preset temperature, the preset PID adjustment formula is used to calculate and obtain

[0091] In an implementable solution, after step S1042, the method further includes:

[0092] In response to the current temperature value of the condenser end being still greater than or equal to the preset temperature value, the steps of obtaining the current temperature value of the condenser end and the current actual voltage value corresponding to the adjustable water valve at the first collection moment after the adjustable water valve is opened, and obtaining the previous historical voltage value corresponding to the adjustable water valve when the temperature of the condenser end reaches the preset temperature for the last time, and using the preset determination strategy to perform calculations to obtain a new target input voltage value corresponding to the adjustable water valve when the temperature of the condenser end reaches the preset temperature, and using the new target input voltage value to control the water flow through the adjustable water valve, and dissipating the heat from the condenser end through the water flow in the heat exchange water tank until the current temperature value of the condenser end is less than the preset temperature value.

[0093] In the present disclosure, after the target input voltage value is calculated to control the water flow rate of the adjustable water valve, the current temperature value at the end of the condenser still does not drop to the preset temperature value (such as 20°C) after the preset time period, the voltage value corresponding to the adjustable water valve when the temperature of the condenser end reaches the preset temperature is taken as the historical record parameter, and then brought into the PID adjustment formula for re-iteration calculation to calculate a new target input voltage value, and the water flow rate of the adjustable water valve is controlled based on the new target input voltage value, and so on, until the optimal hot water exchange volume is quickly obtained, so that the current temperature value of the output condenser end is less than the preset temperature value, so as to achieve the desired heat dissipation effect, thereby ensuring efficient and reliable heat dissipation control.

[0094] In an implementable solution, the heat exchange control method further includes:

[0095] After the adjustable water valve is opened, in response to the existence of the historical record parameter, the steps of obtaining the current temperature value of the condenser end and the current actual voltage value corresponding to the adjustable water valve at the first acquisition moment after the adjustable water valve is opened, and obtaining the previous historical voltage value corresponding to the adjustable water valve when the temperature of the condenser end reached the preset temperature last time are executed;

[0096] In response to the absence of historical record parameters, it is determined that the system is in the first refrigeration operation state, and the current temperature value of the condenser end at the second collection time after the adjustable water valve is opened is obtained; in response to the current temperature value being greater than or equal to the preset temperature value, the input voltage value of the adjustable water valve is increased using the preset adjustment rule, and the step of obtaining the current temperature value of the condenser end at the second collection time after the adjustable water valve is opened is repeated until, in response to the current temperature value being less than the preset temperature value, the preset temperature value and the input voltage value of the adjustable water valve corresponding to the temperature of the condenser end reaching the preset temperature are recorded as historical record parameters for the next refrigeration operation process.

[0097] Specifically, when there is a historical record parameter, the calculation is directly called to obtain the target input voltage value when the temperature at the end of the condenser reaches the preset temperature in the current refrigeration process; if it does not exist, the current is the first refrigeration operation, and the adjustable water valve needs to be fully opened at this time. The flow at the adjustable water valve is Q1, and the actual input voltage value of the adjustable water valve is U1, and the condenser end temperature is T; the actual input voltage value is reduced in a step-by-step manner, and the flow Q1 at the adjustable water valve also gradually decreases. When the condenser end temperature T is the preset temperature value (such as 20°C), the corresponding input voltage U at the adjustable water valve is recorded as a reference value for subsequent PID adjustment formula calculations.

[0098] In the present disclosure, by recording data of the condenser terminal temperature T as a preset temperature value during the first refrigeration operation, the subsequent PID adjustment formula calculation can be iteratively calculated, ensuring the reliability and reliability of determining the input voltage value of the adjustable water valve in each subsequent refrigeration process.

[0099] Combine the following Figure 5 , further specifically illustrate the implementation principle of the heat exchange control method of the water purifier disclosed in the present invention (taking the preset temperature of 20° C. as an example for explanation):

[0100] After the refrigeration system is turned on, determine whether the temperature T at the end of the condenser is less than 20°C. If the temperature T at the end of the condenser is less than 20°C, it means that the heat dissipation at the end of the condenser has reached the requirement.

[0101] If the temperature T at the end of the condenser is greater than or equal to 20°C, the heat dissipation at the end of the condenser has not yet reached the requirement. At this time, the adjustable water valve needs to be controlled to open. Open the adjustable water valve;

[0102] Determine whether there is a historical record parameter. If there is no historical record parameter, after the adjustable water valve is opened for a period of time, continue to measure the latest temperature T at the end of the condenser to determine whether the temperature T at the end of the condenser is less than 20°C. If the temperature T at the end of the condenser is greater than or equal to 20°C, determine to increase the input voltage value of the adjustable water valve to increase the water flow through the adjustable water valve, and obtain the latest temperature T at the end of the condenser after a period of time. After one or more times, until the temperature T at the end of the condenser is less than 20°C, record the corresponding target input voltage value as a historical record parameter for use in the next refrigeration process.

[0103] If there is no historical record parameter, after the adjustable water valve is opened for a period of time, the latest temperature T at the end of the condenser is continued to be determined to see if the temperature T at the end of the condenser is less than 20°C. If so, the corresponding target input voltage value is recorded as a historical record parameter for use in the next refrigeration process.

[0104] If there are historical record parameters, the target input voltage value corresponding to the adjustable water valve when the condenser end reaches 20°C is calculated based on the latest temperature value T at the condenser end, the historical record parameters and the PID control, so as to fine-tune the current input voltage value to the target input voltage value; after a set period of time, if the latest temperature value T at the condenser end is still greater than or equal to 20°C, the step of calculating the target input voltage value corresponding to the adjustable water valve when the condenser end reaches 20°C based on the latest temperature value T at the condenser end, the historical record parameters and the PID control is re-executed to fine-tune the current input voltage value to the target input voltage value until the latest temperature value T at the condenser end is less than 20°C, at which time the corresponding target input voltage value is recorded as a historical record parameter for use in the next refrigeration process.

[0114] Among them, a wastewater solenoid valve is provided on the wastewater waterway, and the two ends of the wastewater waterway are respectively connected to the outlet of the reverse osmosis filter element in the water purification equipment and the heat exchange water tank, and the two ends of the coarse filtered water waterway are respectively connected to the outlet of the pretreatment filter element in the water purification equipment and the heat exchange water tank, and the flow regulating valve is an adjustable water valve. The ambient temperature acquisition module is used to obtain the actual ambient temperature of the environment where the water purification equipment is located;

[0115] Among them, it can be obtained by collecting the ambient temperature sensor. The ambient temperature sensor can be integrated in the water purification equipment, or can be set outside the water purification equipment, as long as the corresponding collected data can be sent to the water purification equipment.

[0116] The water flow regulating module 3 is used to determine the target input voltage value of the flow regulating valve in the target pipeline based on the actual ambient temperature and the preset determination strategy, and to adjust the water flow through the flow regulating valve so that the temperature at the end of the condenser meets the preset temperature range.

[0117] Among them, there is a mapping relationship between the target input voltage value of the flow control valve and the amount of water flowing through it. By accurately controlling the input target input voltage value, the amount of water flowing through it can also be accurately controlled, thereby achieving effective control of the optimal water exchange water volume.

[0118] In this embodiment, by pre-configuring the heat exchange control scheme of the water purification equipment, when the water purification equipment is in an ice-making only working mode, a water-making and ice-making working mode, etc., the water flow in the matching pipeline is driven to flow through the heat exchange water tank to dissipate the heat of the condenser, thereby avoiding the high noise and poor heat dissipation effect caused by the existing use of fans on the condenser, and the condenser can be dissipated in a timely and effective manner; at the same time, the target input voltage value of the flow control valve in the target pipeline can be adaptively adjusted according to the actual ambient temperature, so as to achieve accurate and timely regulation of the amount of water flowing through the flow control valve, achieve the optimal water exchange water volume, and ensure that the temperature value at the end of the condenser can always dynamically and timely meet the heat dissipation requirements; in addition, it can also be adjusted in time with the changes in environmental parameters to ensure that the temperature value at the end of the condenser can always dynamically and timely meet the heat dissipation requirements regardless of different ambient temperatures such as summer and winter, thereby further improving the refrigeration performance of the water purification equipment and the overall product performance.

[0119] Example 4

[0120] like Figure 7 As shown, the heat exchange control device of the water purification equipment of this embodiment is a further improvement of the embodiment 3, specifically:

[0121] In an implementable solution, when the current working mode is a cooling-only working mode, the adjustable water valve is controlled to open, and the step of obtaining the current working mode of the water purification device is performed;

[0122] The heat exchange control device of the water purification equipment of this embodiment also includes:

[0123] A first judgment module 4, for determining that the adjustable water valve remains in a closed state in response to the current temperature value at the end of the condenser being less than a preset temperature value;

[0124] The first judgment module 4 is also used for controlling the adjustable water valve to open and calling the mode acquisition module 1 in response to the current temperature value at the end of the condenser being greater than or equal to the preset temperature value;

[0125] The preset temperature value is determined based on the actual ambient temperature.

[0126] At this time, in the cooling-only working mode, the cooling module works, the adjustable water valve is opened, and the water flow of the adjustable water valve is adjusted according to the preset determination strategy;

[0127] In the working mode of making water and ice at the same time, it is necessary to first confirm whether the adjustable water valve needs to be opened. If necessary, the adjustable water valve is opened and the water flow of the adjustable water valve is adjusted according to the preset strategy; if not, the adjustable water valve is kept in the closed state.

[0128] In the present disclosure, under different working modes, the corresponding water flow control schemes are also different, so as to ensure that the water flow of the adjustable water valve in each working mode can be efficiently and accurately regulated and controlled, thereby ensuring that a good heat dissipation control effect can be achieved regardless of the working mode.

[0129] In an implementable solution, the water volume regulating module 3 is used to obtain the current temperature value of the condenser end and the current actual voltage value corresponding to the adjustable water valve at the first acquisition moment after the adjustable water valve is opened, and obtain the previous historical voltage value corresponding to the adjustable water valve when the temperature of the condenser end reaches the preset temperature last time, and calculate using a preset determination strategy to obtain the target input voltage value corresponding to the adjustable water valve when the temperature of the condenser end reaches the preset temperature;

[0130] The target input voltage value is used to control the water flow through the adjustable water valve, and the water flow in the heat exchange water tank is used to dissipate heat to the condenser end, so that the current temperature value of the condenser end is less than the preset temperature value. In the present disclosure, based on the current temperature value of the condenser end and the current actual voltage value corresponding to the adjustable water valve, and the target input voltage value corresponding to the adjustable water valve when the temperature of the condenser end recorded last time reaches the preset temperature, the preset PID adjustment formula is used to calculate and obtain

[0131] In an implementable solution, the heat exchange control device further includes:

[0132] The water volume regulating module 3 is also used to respond to the current temperature value of the condenser end being still greater than or equal to the preset temperature value, repeatedly execute the steps of obtaining the current temperature value of the condenser end and the current actual voltage value corresponding to the adjustable water valve at the first collection moment after the adjustable water valve is opened, and obtaining the previous historical voltage value corresponding to the adjustable water valve when the temperature of the condenser end reached the preset temperature last time, and using the preset determination strategy to perform calculations to obtain a new target input voltage value corresponding to the adjustable water valve when the temperature of the condenser end reaches the preset temperature, and using the new target input voltage value to control the water flow through the adjustable water valve, and dissipate the heat from the condenser end through the water flow in the heat exchange water tank until the current temperature value of the condenser end is less than the preset temperature value.

[0133] In the present disclosure, after the target input voltage value is calculated to control the water flow rate of the adjustable water valve, the current temperature value at the end of the condenser still does not drop to the preset temperature value (such as 20°C) after the preset time period, the voltage value corresponding to the adjustable water valve when the temperature of the condenser end reaches the preset temperature is taken as the historical record parameter, and then brought into the PID adjustment formula for re-iteration calculation to calculate a new target input voltage value, and the water flow rate of the adjustable water valve is controlled based on the new target input voltage value, and so on, until the optimal hot water exchange volume is quickly obtained, so that the current temperature value of the output condenser end is less than the preset temperature value, so as to achieve the desired heat dissipation effect, thereby ensuring efficient and reliable heat dissipation control.

[0134] In an implementable solution, the heat exchange control device further includes:

[0135] The second judgment module 5 is used for, after the adjustable water valve is opened, in response to the existence of the historical record parameter, executing the steps of obtaining the current temperature value of the condenser end and the current actual voltage value corresponding to the adjustable water valve at the first collection moment after the adjustable water valve is opened, and obtaining the previous historical voltage value corresponding to the adjustable water valve when the temperature of the condenser end reached the preset temperature last time;

[0136] The second judgment module 5 is also used to determine that it is in the first refrigeration operation state in response to the absence of historical record parameters, and obtain the current temperature value of the condenser end at the second collection time after the adjustable water valve is opened; in response to the current temperature value being greater than or equal to the preset temperature value, the preset adjustment rule is used to increase the input voltage value of the adjustable water valve, and the step of obtaining the current temperature value of the condenser end at the second collection time after the adjustable water valve is opened is repeated until the current temperature value is less than the preset temperature value, and the preset temperature value and the input voltage value of the adjustable water valve corresponding to the temperature of the condenser end reaches the preset temperature are recorded as the historical record parameters of the next refrigeration operation process.

[0137] Specifically, when there is a historical record parameter, the calculation is directly called to obtain the target input voltage value when the temperature at the end of the condenser reaches the preset temperature in the current refrigeration process; if it does not exist, the current is the first refrigeration operation, and the adjustable water valve needs to be fully opened at this time. The flow at the adjustable water valve is Q1, and the actual input voltage value of the adjustable water valve is U1, and the condenser end temperature is T; the actual input voltage value is reduced in a step-by-step manner, and the flow Q1 at the adjustable water valve also gradually decreases. When the condenser end temperature T is the preset temperature value (such as 20°C), the corresponding input voltage U at the adjustable water valve is recorded as a reference value for subsequent PID adjustment formula calculations.

[0138] In the present disclosure, by recording data of the condenser terminal temperature T as a preset temperature value during the first refrigeration operation, the subsequent PID adjustment formula calculation can be iteratively calculated, ensuring the reliability and reliability of determining the input voltage value of the adjustable water valve in each subsequent refrigeration process.
