The invention provides a control method of a water dispenser.
In an embodiment of the present invention, as shown in fig. 1 to 4, the water dispenser refrigeration system includes:
a cold tank 10 having a circulating water inlet 11 and a water outlet 12;
a heat exchanger for exchanging heat with water in the cold tank 10;
the water inlet end of the circulating water pump 20 is communicated with the water outlet 12, and the water outlet end of the circulating water pump 20 is communicated with the circulating water inlet 11;
the control method of the water dispenser comprises the following steps:
s1: during the refrigeration process, a first detected water temperature in the cooling tank 10 is obtained;
s2: comparing the first detected water temperature with a first preset temperature, and if the first detected water temperature is smaller than or equal to the first preset temperature, executing step S3;
s3: the circulating water pump 20 is started.
In this embodiment, the water dispenser refrigeration system further includes a compressor, a temperature sensor and a controller, the compressor is used for driving the heat exchanger to operate, the heat exchanger is installed on the outer wall of the cold tank 10, and the start or the stop of the heat exchanger can be controlled by controlling the start or the stop of the compressor, so as to control the refrigeration process of water in the cold tank 10. The temperature sensor is used for detecting the water temperature in the cold tank 10, and the controller is used for controlling the starting of the circulating water pump 20 according to the detection signal of the temperature sensor. Specifically, in the refrigeration process, the compressor is in an on state, that is, the heat exchanger and the water in the cold tank 10 exchange heat effectively to cool the water in the cold tank 10, the temperature sensor monitors the water temperature in the cold tank 10 in real time and transmits a detection signal to the controller, and the controller judges whether to start the circulating water pump 20 to circulate the water in the cold tank 10 by comparing the first detection water temperature with the first preset temperature. It should be noted that the detection area of the water in the cold tank 10 by the temperature sensor is preferably close to the heat exchanger, i.e., the lowest water temperature in the cold tank 10 is detected. If the first detected water temperature is less than or equal to the first preset temperature, the controller controls the circulating water pump 20 to start, and promotes the water circulation flow in the cold tank 10, so that the water in the low temperature area and the water in other areas in the cold tank 10 can more efficiently perform heat transfer, and the overall cooling efficiency of the water in the cold tank 10 is higher, and the cooling period is shorter.
The first preset temperature may be 14.5 ℃ to 15.5 ℃, preferably 15 ℃, and if the first preset temperature is less than 14.5 ℃, the water temperature in the cold tank 10 will take longer to drop to the first preset temperature, i.e. the compressor will need to work longer, thereby increasing the energy consumption of the compressor; if the first preset time period is longer than 15.5 ℃, the starting time of the circulating water pump 20 is more advanced, which means that the circulating water pump 20 can work for a longer time before the water temperature is reduced to the next preset temperature, and the energy consumption of the circulating water pump 20 is improved; therefore, the first preset temperature is set to be 14.5 ℃ to 15.5 ℃, so that the energy consumption of the refrigerating system of the water dispenser can be effectively reduced on the basis of shortening the refrigerating cycle of the refrigerating system of the water dispenser.
Further, as shown in fig. 2, after the step S3, the control method of the water dispenser further includes:
s4: comparing the first detected water temperature with a second preset temperature, and executing step S5 if the first detected water temperature is smaller than the second preset temperature; wherein the second preset temperature is less than the first preset temperature;
s5: the circulating water pump 20 is turned off.
In this embodiment, after step S3, that is, after the circulating water pump 20 is turned on, the compressor continues to operate to continuously reduce the water temperature in the cold tank 10, and the first detected water temperature is the water temperature after the circulating water pump 20 is turned on. The second preset temperature is smaller than the first preset temperature, if the first detected water temperature is smaller than or equal to the second preset temperature, the circulating water pump 20 is turned off, that is, when the water temperature in the cold tank 10 is reduced to the second preset temperature, the water temperature is lower as a whole, and the circulating flow of the water in the cold tank 10 can not obviously promote the heat transfer of the water in different areas, so that the circulating flow of the water in the cold tank 10 can not be realized any more, that is, the circulating water pump 20 can be turned off, so that the energy consumption is reduced. Thus, the water temperature in the cold tank 10 is greater than the second preset temperature and less than the first preset temperature in the open environment of the circulating water pump 20.
The second preset temperature may be 3.5 ℃ to 4.5 ℃, preferably 4 ℃, if the second preset temperature is less than 3.5 ℃, the circulating water pump 20 will work for a longer time, and the circulating water pump 20 working at this time cannot effectively improve the refrigeration efficiency of the cold tank 10, thereby improving the energy consumption; if the second preset temperature is greater than 4.5 ℃, the circulating water pump 20 is turned off in advance when the heat transfer of the water in the cold tank 10 is also promoted, resulting in a reduction in the refrigerating speed, and the compressor needs to be operated for a longer time, thereby increasing the energy consumption. Therefore, the second preset temperature is set to be 3.5 ℃ to 4.5 ℃, so that the energy consumption of the refrigerating system of the water dispenser can be effectively reduced on the basis of shortening the refrigerating cycle of the refrigerating system of the water dispenser.
Further, the control method of the water dispenser further comprises the following steps:
s6: during the cooling process, a second detected water temperature in the cooling tank 10 is obtained;
s7: comparing the second detected water temperature with a third preset temperature, and executing step S8 if the second detected water temperature is smaller than or equal to the third preset temperature; the third preset temperature is less than the second preset temperature;
s8: and closing the heat exchanger.
In this embodiment, after step S5, i.e. after the circulating water pump 20 is turned off, the compressor continues to operate first, i.e. the heat exchanger continues to refrigerate the water in the cold tank 10, and the water temperature continues to decrease, at which time the second detected water temperature is the water temperature after the circulating water pump 20 is turned off. The third preset temperature is smaller than the second preset temperature, that is, the third preset temperature can be used as a target temperature in the refrigerating process, and when the water temperature in the cold tank 10 reaches the target temperature, the heat exchanger can stop working so as to prevent the water temperature from being too low or increase the energy consumption.
The third preset temperature may be 1.5 ℃ to 2.5 ℃, preferably 2 ℃, and if the third preset temperature is less than 1.5 ℃, the compressor needs to work for a longer time, and the user does not need lower-temperature water, so that the water which is continuously cooled does not meet more user requirements, but can increase energy consumption; if the third preset temperature is higher than 2.5 ℃, the refrigeration temperature is not low enough, and the refrigeration effect is poor. Therefore, the third preset temperature is set to be 1.5 ℃ to 2.5 ℃, so that the energy consumption of the refrigerating system of the water dispenser can be effectively reduced on the basis of shortening the refrigerating effect of the refrigerating system of the water dispenser.
Further, as shown in fig. 3, the control method of the water dispenser further includes:
s9: in the refrigeration process, acquiring a first operation time length of the heat exchanger;
s10: comparing the first operation time length with a first preset time length, and executing step S11 if the first operation time length is greater than or equal to the first preset time length;
s11: and closing the heat exchanger.
In this embodiment, the water dispenser refrigeration system further includes a timing sensor, configured to record an operation duration of the compressor, that is, an operation duration of the heat exchanger, where the timing sensor sends a real-time operation duration signal of the compressor to the controller, and the controller compares the first operation duration with a first preset duration, and then controls the compressor according to a comparison result. In combination with the above embodiment, in the cooling process, regardless of whether the water temperature in the cooling tank 10 is reduced to the target temperature, the compressor is turned off as long as the first operation time period of the heat exchanger is longer than or equal to the first preset time period, so that the invalid operation time period of the heat exchanger is reduced, and the energy consumption is reduced.
The first preset duration is 115 minutes to 125 minutes, preferably 120 minutes, and if the first preset duration is less than 115 minutes, the water temperature in the cold tank 10 may not be reduced to the target temperature in time, so that the refrigeration effect is reduced; if the first preset time is longer than 125 minutes, the invalid operation time of the heat exchanger is prolonged, so that the water temperature cannot be reduced to the target temperature, and the energy consumption is increased; therefore, the first preset time is set to 115 minutes to 125 minutes, so that the refrigerating effect can be effectively improved, and the energy consumption can be reduced.
Further, as shown in fig. 4, the control method of the water dispenser further includes:
s12: during the heat preservation process, a third detected water temperature in the cold tank 10 is obtained;
s13: comparing the third detected water temperature with a fourth preset temperature, and if the third detected water temperature is greater than or equal to the fourth preset temperature, executing step S14; the fourth preset temperature is greater than the second preset temperature;
s14: the heat exchanger and the circulating water pump 20 are started.
In this embodiment, after the water temperature in the cold tank 10 reaches the target temperature, the heat exchanger is turned off, the refrigeration process is ended, the refrigeration system enters the heat preservation process, during the heat preservation process, the water in the cold tank 10 exchanges heat with the surrounding environment of the cold tank 10 to raise the temperature, when the cold water is raised to the fourth preset temperature, the controller controls the circulating water pump 20 to be started, and at this time, the third detected water temperature is the water temperature after the heat exchanger is turned off. It should be noted that, at this time, the temperature sensor may include a temperature control portion directly electrically connected to the compressor, that is, when the third detected water temperature is greater than or equal to the fourth preset temperature, the temperature control portion may directly control the compressor to be turned on, that is, without passing through the controller, so that the temperature sensor and the compressor can be independently linked under the preset condition, thereby improving the reaction speed of the compressor and reducing the processing content of the controller. Through the temperature change of the water in the cold tank 10 of real-time supervision in the thermal insulation process to start the compressor according to the relation of third detected temperature and fourth preset temperature, start the heat exchanger promptly, and circulating water pump 20, make refrigerating system get into the refrigeration process again, can effectively guarantee that the temperature of water in the cold tank 10 is low enough, improve refrigerating system holistic refrigeration effect.
In practical application, as shown in fig. 4, after the step S14, the control method of the water dispenser further includes:
s20: acquiring a fifth detected water temperature in the cold tank 10;
s21: comparing the fifth detected water temperature with the second preset temperature; if the fifth detected water temperature is less than or equal to the second preset temperature, executing step S22;
s22: turning off the circulating water pump 20;
and/or the number of the groups of groups,
s23: obtaining a sixth detected water temperature in the cold tank;
s24: comparing the sixth detected water temperature with the third preset temperature, and executing step S25 if the sixth detected water temperature is less than or equal to the third preset temperature;
s25: and closing the heat exchanger.
In combination with the above embodiment, after the compressor and the circulating water pump 20 are restarted, when the water temperature of the cooling tank 10 reaches the second preset temperature, the circulating water pump 20 is turned off again; when the water temperature of the cold tank 10 reaches a third preset temperature, the compressor, i.e. the heat exchanger is turned off again; therefore, closed-loop control of the circulating water pump 20 and the heat exchanger can be realized in the switching of the refrigerating process and the heat preservation process, and the overall convenience and practicality of the refrigerating system control method are improved.
The fourth preset temperature is 5.5 ℃ to 6.5 ℃; preferably, the temperature is 6 ℃, if the fourth preset temperature is less than 5.5 ℃, the heat exchanger and the circulating water pump 20 can be started prematurely, the running time of the heat exchanger and the circulating water pump 20 is prolonged, the energy consumption is increased, and the refrigerating effect is not obvious; if the fourth preset temperature is greater than 6.5 ℃, the heat exchanger and the circulating water pump 20 are started too late, so that the heat exchanger and the circulating water pump 20 need to operate for a longer time to enable the water temperature to reach the target temperature, the operation time of the heat exchanger and the circulating water pump 20 is prolonged, and the energy consumption is increased; therefore, the fourth preset temperature is set to be 5.5 ℃ to 6.5 ℃, so that the refrigerating effect can be effectively improved, and the energy consumption can be reduced.
Further, as shown in fig. 4, after the step S14, the control method of the water dispenser further includes:
s15: acquiring a fourth detected water temperature in the cold tank and a second operation time length of the heat exchanger;
s16: comparing the fourth detected water temperature with a fifth preset temperature and comparing the second operation duration with a second preset duration, and if the fourth detected water temperature is less than or equal to the fifth preset temperature and the second operation duration is greater than or equal to the second preset duration, executing step S17; the fifth preset temperature is greater than the third preset temperature;
s17: and closing the heat exchanger.
In this embodiment, after the heat exchanger operates again in the heat preservation process, if the water temperature in the cold tank 10 is less than or equal to the fifth preset temperature but still greater than the target temperature, and the operation duration of the heat exchanger has exceeded the second preset duration, the heat exchanger is forcibly turned off, so as to reduce the ineffective operation time of the heat exchanger and reduce the energy consumption.
The fifth preset temperature is 7.5 ℃ to 8.5 ℃, preferably 8 ℃; the second run length is from 35 minutes to 45 minutes, preferably 40 minutes; if the fifth preset temperature is less than 7.5 ℃, the second operation time is less than 35 minutes, the water temperature in the cold tank 10 may not be reduced to the target temperature in time, thereby reducing the refrigeration effect; if the fifth preset temperature is higher than 8.5 ℃, and the second operation time is longer than 45 minutes, the invalid operation time of the heat exchanger is prolonged, so that the water temperature cannot be reduced to the target temperature, and the energy consumption is increased; therefore, the fifth preset temperature is set to 7.5 ℃ to 8.5 ℃, and the second preset time period is set to 35 minutes to 45 minutes, so that the refrigerating effect can be effectively improved, and the energy consumption can be reduced.
Further, as shown in fig. 4, after the step S15, the control method of the water dispenser further includes:
