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 refrigeration system of the water dispenser includes:
a cooling tank 10 having a circulating water inlet 11 and a water outlet 12;
a heat exchanger for exchanging heat with the 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: in the refrigeration process, acquiring a first detected water temperature in the cold tank 10;
s2: comparing the first detected water temperature with a first preset temperature, and if the first detected water temperature is less than or equal to the first preset temperature, performing step S3;
s3: the circulation water pump 20 is started.
In this embodiment, the refrigeration system of the water dispenser further comprises 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 cooling tank 10, and the start and stop of the heat exchanger can be controlled by controlling the start and stop of the compressor, so that the refrigeration process of water in the cooling tank 10 is controlled. The temperature sensor is used for detecting the temperature of water in the cold tank 10, and the controller is used for controlling the start of the circulating water pump 20 according to the detection signal of the temperature sensor. Specifically, in the refrigeration process, the compressor is in the on-state, and the effective heat transfer of heat exchanger and the water in the cold jar 10 is so that the water in the cold jar 10 cools down promptly, and temperature sensor carries out real-time supervision to the temperature of water in the cold jar 10 to with detected signal transmission to controller, the controller is through comparing first detection temperature and first temperature of predetermineeing, judges whether start circulating water pump 20 makes the water circulation in the cold jar 10 flow. 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 in the cooling tank 10 to circularly flow, so that the water in the low-temperature region in the cooling tank 10 and the water in other regions can be more efficiently transferred, the overall cooling efficiency of the water in the cooling tank 10 is higher, and the refrigeration cycle is shorter.
The first preset temperature can be 14.5-15.5 ℃, preferably 15 ℃, and if the first preset temperature is less than 14.5 ℃, the water temperature in the cold tank 10 is reduced to the first preset temperature, which requires a longer time, that is, the compressor needs to work for a longer time, so that the energy consumption of the compressor is improved; if the first preset time is longer than 15.5 ℃, the start of the circulating water pump 20 is more advanced, which means that the circulating water pump 20 works 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 14.5-15.5 ℃, and the energy consumption of the water dispenser refrigerating system can be effectively reduced on the basis of shortening the refrigerating cycle of the water dispenser refrigerating system.
Further, as shown in fig. 2, after the step S3, the method for controlling a water dispenser further includes:
s4: comparing the first detected water temperature with a second preset temperature, and if the first detected water temperature is lower than the second preset temperature, executing step S5; wherein the second preset temperature is lower than the first preset temperature;
s5: the circulation water pump 20 is turned off.
In the present embodiment, after step S3, i.e., after the circulation water pump 20 is turned on, the compressor continues to operate to further decrease the water temperature in the cold tank 10, and the first detected water temperature is the water temperature after the circulation water pump 20 is turned on. The second preset temperature is lower than the first preset temperature, and if the first detected water temperature is lower than or equal to the second preset temperature, the water circulating pump 20 is turned off, that is, when the water temperature in the cold tank 10 is lowered to the second preset temperature, the water temperature is integrally low, and the circulating flow of the water in the cold tank 10 cannot obviously promote the heat transfer of the water in different areas, so that the water circulating flow in the cold tank 10 can no longer be realized, that is, the water circulating pump 20 can be turned off, so as to reduce energy consumption. Therefore, the water temperature in the cold tank 10 is higher than the second preset temperature and lower than the first preset temperature in the starting environment of the water circulating pump 20.
The second preset temperature may be 3.5 ℃ to 4.5 ℃, preferably 4 ℃, and if the second preset temperature is less than 3.5 ℃, the circulating water pump 20 may operate for a longer time, and the operating circulating water pump 20 cannot effectively improve the refrigeration efficiency of the cold tank 10, thereby increasing energy consumption; if the second preset temperature is greater than 4.5 ℃, the circulating water pump 20 is turned off in advance while also promoting the heat transfer of the water in the cold tank 10, resulting in a reduction in the cooling speed and a longer time required for the compressor to operate, increasing the energy consumption. Therefore, the second preset temperature is set to be 3.5-4.5 ℃, and the energy consumption of the water dispenser refrigerating system can be effectively reduced on the basis of shortening the refrigerating cycle of the water dispenser refrigerating system.
Further, the control method of the water dispenser further comprises the following steps:
s6: in the refrigeration process, acquiring a second detected water temperature in the cold tank 10;
s7: comparing the second detected water temperature with a third preset temperature, and if the second detected water temperature is less than or equal to the third preset temperature, performing step S8; the third preset temperature is lower than the second preset temperature;
s8: the heat exchanger is shut down.
In this embodiment, after step S5, i.e., after the circulation water pump 20 is turned off, the compressor continues to operate, i.e., the heat exchanger continues to cool the water in the cold tank 10, and the water temperature continues to decrease, and at this time, the second detected water temperature is the water temperature after the circulation water pump 20 is turned off. The third preset temperature is lower than the second preset temperature, that is, the third preset temperature can be used as the target temperature of the refrigeration 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 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 since the user does not need lower temperature water, the water continuously cooled does not meet more user requirements, and the energy consumption is increased; if the third preset temperature is higher than 2.5 ℃, the refrigerating temperature is not low enough, and the refrigerating effect is not good. Therefore, the third preset temperature is set to be 1.5-2.5 ℃, and the energy consumption of the refrigeration system of the water dispenser can be effectively reduced on the basis of shortening the refrigeration effect of the refrigeration 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 duration with a first preset duration, and if the first operation duration is greater than or equal to the first preset duration, executing step S11;
s11: the heat exchanger is shut down.
In this embodiment, the refrigeration system of the water dispenser further comprises a timing sensor for recording the operation duration of the compressor, namely the operation duration of the heat exchanger, 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 controls the compressor according to the comparison result. With reference to the above embodiment, during the refrigeration process, regardless of whether the temperature of the water in the cold tank 10 is reduced to the target temperature, as long as the first operation time period of the heat exchanger is greater than or equal to the first preset time period, the compressor is turned off, so as to reduce the invalid operation time of the heat exchanger and reduce the energy consumption.
The first preset time is 115 minutes to 125 minutes, preferably 120 minutes, and if the first preset time is less than 115 minutes, the temperature of the water 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 period is set to be 115 minutes to 125 minutes, so that the refrigeration 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: in the heat preservation process, acquiring a third detected water temperature in the cold tank 10;
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 higher than the second preset temperature;
s14: the heat exchanger and circulating water pump 20 is started.
In this embodiment, after the water temperature in the cold tank 10 reaches the target temperature, the heat exchanger is closed, the refrigeration process is finished, the refrigeration system enters the heat preservation process, in the heat preservation process, the water in the cold tank 10 exchanges heat with the ambient environment of the cold tank 10 to heat up, when the cold water is heated up to the fourth preset temperature, the controller controls the circulating water pump 20 to start, and at this time, the third detected water temperature is the water temperature after the heat exchanger is closed. 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 may be independently linked with the compressor under the preset condition, thereby increasing the reaction speed of the compressor and reducing the processing content of the controller. Through at the in-process that keeps warm, the temperature variation of real-time supervision cold cylinder 10 interior water to start the compressor according to the relation of third detection temperature and fourth preset temperature, start the heat exchanger promptly, and circulating water pump 20 makes refrigerating system get into the refrigeration process once more, can effectively guarantee that the temperature in the cold cylinder 10 is enough low, improves the holistic refrigeration effect of refrigerating system.
In practical application, as shown in fig. 4, after the step S14, the method for controlling a water dispenser further includes:
s20: acquiring a fifth detected water temperature in the cold tank 10;

s24: comparing the sixth detected water temperature with the third preset temperature, and if the sixth detected water temperature is less than or equal to the third preset temperature, performing step S25;
s25: the heat exchanger is shut down.
With the above embodiment, after the compressor and the water circulation pump 20 are started again, when the water temperature of the cold tank 10 reaches the second preset temperature, the water circulation 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 closed again; therefore, closed-loop control over the circulating water pump 20 and the heat exchanger can be realized in switching between the refrigeration process and the heat preservation process, and the overall convenience and practicability of the control method of the refrigeration system are improved.
The fourth preset temperature is 5.5-6.5 ℃; preferably 6 ℃, if the fourth preset temperature is less than 5.5 ℃, the heat exchanger and the circulating water pump 20 will 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 refrigeration effect is not obvious; if the fourth preset temperature is higher 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 run for a longer time to enable the water temperature to reach the target temperature, the running 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 5.5-6.5 ℃, so that the refrigeration effect can be effectively improved, and the energy consumption can be reduced.

s17: the heat exchanger is shut down.
In this embodiment, after the heat exchanger operates again in the heat preservation process, if the temperature of the water in the cooling 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 exceeds the second preset duration, the heat exchanger is forcibly closed, so as to reduce the invalid operation time of the heat exchanger and reduce the energy consumption.
The fifth preset temperature is 7.5-8.5 ℃, and is preferably 8 ℃; the second operating time period is 35 minutes to 45 minutes, preferably 40 minutes; if the fifth preset temperature is less than 7.5 ℃, and 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, so that the refrigeration effect is reduced; 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 be 7.5-8.5 ℃, and the second preset time is set to be 35-45 minutes, so that the refrigeration effect can be effectively improved, and the energy consumption is reduced.
