As shown in fig. 2, the double tube evaporator 210, which includes an inner tube 270 through which cold water flows and an outer tube 260 through which a refrigerant flows, and the above-described module for cooling the refrigerant, is provided with a double tube cooling power saving structure in which cold water and the refrigerant, which exchange heat with each other, are supplied to the double tube evaporator, and water can be discharged from the double tube evaporator 210 through a water outlet portion after the refrigerant is cooled.
The compressor 280 compresses the gaseous refrigerant supplied from the dual pipe evaporator 210 into a high temperature and high pressure liquid state. The condenser 290 condenses the compressed refrigerant by radiating high temperature contained in the refrigerant to the outside through the compressor. In order to radiate high heat from the condenser 290, a condensing fan may be added.
In addition, the expansion device 300 may cause the condensed refrigerant (i.e., refrigerant) to change phase due to a low temperature and a low pressure, and the refrigerant may be supplied to the dual tube evaporator 210 in the above process. The refrigerant supplied from the dual-tube evaporator 210 exchanges heat with the drinking water and is then supplied to the compressor 280. The expansion device 300 comprises a capillary tube.
In this embodiment, the dual-pipe cooling electricity-saving structure further includes a display unit 190 and a cold water temperature detection unit 120;
the cold water temperature detection unit 120 is configured to detect a cold water temperature of the cold water, and send the cold water temperature to the control unit 200;
the control unit 200 is further configured to activate a water outlet button on the display unit 190 when the temperature of the cold water is a preset temperature;
the display unit 190 is configured to display whether the water outlet button is activated.
It can be understood that the dual-pipe cooling electricity-saving structure further includes an evaporator refrigerant temperature detection unit, the evaporator refrigerant temperature detection unit is configured to detect the temperature of the refrigerant through an evaporator refrigerant inlet temperature sensor 240 and an evaporator refrigerant outlet temperature sensor 220, the cold water temperature detection unit 120 detects the temperature of the output cold water through a cold water outlet side temperature sensor 250, and detects the temperature of the input cold water through a cold water inlet side temperature sensor 230.
It should be understood that the water output detecting unit 130 detects the water output, when the user drinks, the water output detecting unit can detect the water output and output the water output of the cold water, and the control unit 200 receives the water output of the cold water and stores the water output in the memory. The control unit 200 accumulates the water output of the cold water in intervals, wherein the interval is in hours, the interval is 24 days, the user accumulated usage amount is calculated and stored in the interval water output accumulation manner.
It should be noted that the cold water temperature detection unit 120 may detect the cold water temperature. The control unit 200 receives the cold water temperature. Then, the control unit 200 calculates the average water yield from the water yields stored in the memory. The average water yield is typically: (same interval + present interval on previous day)/2, with each interval updated in real time. The control unit 200 determines whether the average water yield is lower than the preset water yield threshold, for example, whether the average water yield threshold is smaller than 50ml, if so, it indicates that the water yield is smaller. When the average water yield is smaller than the preset water yield threshold, the control unit 200 stops cooling, does not perform cooling start, and keeps a standby state, that is, the water outlet button is not activated.
In this embodiment, the dual-tube cooling power saving structure further includes a driving unit 170;
the control unit 200 is configured to set a temperature adjustment signal according to the average water yield and the cold water temperature when the average water yield is greater than or equal to the preset water yield threshold, and send the temperature adjustment signal to the control unit 200;
the control unit 200 is further configured to drive the driving unit 170 according to the temperature adjustment signal;
the driving unit 170 is configured to drive the cooling module 180 according to the temperature adjustment signal;
and the cooling module 180 is used for controlling the temperature of the cold water according to the temperature adjusting signal.
In a specific implementation, a user may select cold water start through the input portion of the display unit 190, the control unit 200 drives the driving portion to start the cooling module 180 to perform cooling until the set temperature is reached, and the cooling time from the start of cooling to the set temperature is about 10 minutes. Then, when the set temperature is reached, the control unit 200 activates a water outlet button at the display unit 190 to inform the user that cold water can be discharged. The set temperature is characterized in that the average water yield is 2-12 ℃ when the average water yield is more than 1L, and the average water yield is 8-12 ℃ when the average water yield is less than 400 ml. For example, when the average water yield is more than 1L, if the temperature of the cold water is lower than 2 to 12 ℃, the temperature adjustment signal is set to be the increased temperature, the temperature adjustment signal for increasing the temperature is sent to the control unit 200, the control unit 200 drives the driving unit 170, the driving unit 170 drives the cooling module 180, the cooling module 180 adjusts the temperature of the evaporator to increase the temperature of the cold water so that the temperature of the cold water meets 2 to 12 ℃, and the control modes in other cases are similar and are not described herein again.
The control unit 200 keeps the cooling operation while the cold water discharging operation continues, and when the temperature of the cold water rises beyond a certain time after the cold water stops, the water discharging button needs to be deactivated to inform the user that cooling is required. At this time, the notification flag of the display unit 190 may be displayed by a stage, a color, and/or a number, etc. When the average water output is 45 to 55ml or more, the control unit 200 controls the cooling operation according to the corresponding average water output, and controls the driving section.
In this embodiment, the dual-pipe cooling electricity-saving structure further includes an evaporator temperature detection unit 110;
the evaporator temperature detecting unit 110 for detecting an outlet temperature of the dual pipe evaporator 210;
the control unit 200 is configured to receive an outlet temperature of the dual-tube evaporator 210, generate a control instruction according to the outlet temperature of the dual-tube evaporator 210, and control the driving unit 170;
the driving unit 170 is further configured to start or stop the cooling module 180 according to the control instruction.
It should be understood that, in order to accurately control the temperature of the cold water, at least one of the cold water temperature detection unit 120 or the evaporator temperature detection unit 110 may be provided, and the evaporator temperature detection unit 110 may use one sensor or two sensors, which is not limited in this embodiment.
It can be understood that the control unit 200 judges whether the cold water is selected according to the operation of the input part in the maximum power saving mode. If the cooling operation is selected, the control unit 200 determines whether the outlet temperature of the evaporator exceeds a preset outlet temperature, which may be 3 ℃, i.e., determines whether the outlet temperature of the evaporator is above 3 ℃. When the outlet temperature of the evaporator is above 3 ℃, the control unit 200 controls the driving unit 170 and starts the cooling module 180 composed of the compressor, the fan, and the like. The time to stop cooling is then initialized.
When the outlet temperature of the evaporator is less than 3 ℃, the control unit 200 controls the driving unit 170 to stop the operation of the cooling module 180 including the compressor, the fan, and the like. In addition, if the water outlet button among the plurality of marks of the display unit 190 is activated, that is, the cold water meets the preset temperature, the water outlet operation can be performed, the control unit 200 determines whether a preset time, which may be 10 minutes, has elapsed after the cooling is stopped, if the preset time has elapsed, the control unit 200 notifies the plurality of marks of the water outlet button of the display unit 190 that the marks are inactive, indicating that the cold water cannot be discharged, and if the cooling stop time does not exceed 10 minutes, the step of returning to the step of determining whether the cold water is selected starts to repeatedly perform the above operation process.
It should be understood that the control unit 200 determines whether the pattern recognition interval is the initial 24 hours or the valid pattern third section after changing to the next interval after 1 hour. In the pattern recognition interval, the temperature of the control unit 200 is controlled to be 2-12 ℃, and then the control unit 200 judges whether cold water is produced. And when the cold water is not discharged, repeatedly executing the step of judging whether the cold water is in the mode identification section or not. When the cold water is discharged, the control unit 200 accumulates the water discharge amount per hour, stores the water discharge amount, and repeatedly executes the step of judging whether the cold water is in the mode identification interval. In addition, if the current interval is not in the pattern recognition interval, the average water yield of the current interval is calculated, the control unit 200 determines whether the average water yield of the current interval is greater than or equal to a preset water yield threshold, where the preset water yield threshold may be 50ml, that is, whether the average water yield of the current interval is greater than or equal to 50ml, the control unit 200 determines whether the average water yield of the current interval is greater than or equal to 1 liter, and when the water yield of the current interval is greater than or equal to 1 liter, the control unit 200 performs temperature control to control the temperature of the cold water of the discharged water to be 2-12 ℃. On the other hand, if the average water yield of the current interval is less than 1 liter, whether the average water yield of the current interval is more than 400 milliliters is judged, and when the average water yield of the current interval is more than 400 milliliters, the control unit 200 performs temperature control to control the temperature of the cold water of the discharged water to be 5-12 ℃. In addition, if the water yield of the current interval does not exceed 400 milliliters, the control unit 200 controls the temperature and controls the temperature of the cold water of the discharged water to be 8-12 ℃. The above process can be modified in various ways as required, and the temperature control range or sequence can be modified.
In this embodiment, the dual-tube evaporator circulates the water through the inner tube, circulates the refrigerant through the outer tube, performs heat exchange between the water in the inner tube and the refrigerant in the outer tube, cools the water through the refrigerant, and outputs cooled cold water, without storing cold water through a cold water tank, thereby avoiding the problem of insanitation caused by the stored cold water being in a contaminated state due to contamination of the cold water tank; the temperature of the cold water is controlled according to the average water outlet quantity, the electricity consumption caused by the fact that the temperature of the cold water is too low is avoided, the output cold water is prevented from not meeting the temperature requirement of a user on the cold water, and therefore the purpose of efficiently discharging the cold water while saving electricity is achieved.
