Preferably, the filter element 3 of this embodiment may be a reverse osmosis composite filter element.

The refrigeration assembly comprises a compressor 5, a radiator 6 and an evaporator 7 which are connected in sequence, wherein the evaporator 7 is used for refrigerating water in the cold water tank 2. The compressor 5, the radiator 6 and the evaporator 7 are respectively communicated through pipelines, and refrigerant flows in the pipelines. The compressor 5 serves to draw gaseous refrigerant from the evaporator 7 and compress the refrigerant vapor to raise its pressure and temperature, and to press the refrigerant vapor at high temperature and high pressure into the radiator 6.

The first circulation line 8 includes a first line communicating the waste water tank 4 with the cold medium inlet on the radiator 6 and a second line communicating the waste water tank 4 with the cold medium outlet on the radiator 6. The first water pump 9 may be provided on the first line or on the second line. The waste water in the waste water tank 4 is pumped into the cooling medium flow passage in the radiator 6 by the first water pump 9 to absorb the heat of the high-temperature and high-pressure refrigerant vapor flowing in the heating medium flow passage, thereby cooling and liquefying the refrigerant vapor.

The wastewater tank 4 in the kitchen water making system provided by the embodiment can store the wastewater filtered by the filtering piece 3, and simultaneously can use the filtered wastewater for carrying out cold-heat exchange with the radiator 6, so that the refrigerating efficiency is effectively improved while the water resource is saved, and the environment applicability of the water making system is strong.

As shown in fig. 1, in some embodiments, the evaporator 7 may be disposed inside the cold water tank 2, where the evaporator 7 is directly in contact with water in the cold water tank 2, and the evaporator 7 may be in a tube structure, where the liquefied refrigerant flowing into the evaporator 7 can absorb the temperature in the cold water tank 2 to evaporate, so that the water in the cold water tank 2 can be quickly cooled.

As shown in fig. 2, in some embodiments, the evaporator 7 may also be provided outside the cold water tank 2. At this time, the evaporator 7 has a structure similar to that of the radiator 6, and mainly includes a tube side and a shell side.

The first temperature detector 12 is electrically connected to the overall controller, and the first temperature detector 12 is configured to detect a temperature of cold water in the cold water tank 2 and is capable of sending a first signal or a second signal to the overall controller.

Specifically, when the cold water tank 2 is cooled, the compressor 5 and the first water pump 9 are both operated, when the first temperature detector 12 in the cold water tank 2 detects that the water temperature is reduced to the first water temperature threshold value, a first signal is generated and sent to the master controller, and the master controller receives the first signal and simultaneously turns off the compressor 5 and the first water pump 9 to stop the cooling operation; when the first temperature detector 12 in the cold water tank 2 detects that the water temperature is higher than the second temperature threshold value, a second signal is generated and sent to the main controller, and the main controller simultaneously turns on the compressor 5 and the first water pump 9 to start the refrigeration operation after receiving the second signal. By arranging the first temperature detector 12, the compressor 5 and the first water pump 9 can be automatically started or shut down according to the water temperature in the cold water tank 2, and the degree of automation is improved.

The first water temperature threshold and the second water temperature threshold of this embodiment may be manually set, for example, the first water temperature threshold is 4 ℃, and the second water temperature threshold is 8 ℃.

Further, in some embodiments, the under-kitchen water making system further comprises a drain solenoid valve 13, wherein the water inlet of the drain solenoid valve 13 is communicated with the water outlet of the wastewater tank 4, and the water outlet of the drain solenoid valve 13 is communicated with the floor drain 20. The drain solenoid valve 13 is configured to conduct the drain tank 4 and the floor drain 20 when energized, and to interrupt the conduction between the drain tank 4 and the floor drain 20 when de-energized.

The drain solenoid valve 13 of the present embodiment is also electrically connected to the overall controller. As the waste water in the waste water tank 4 is used for cold-heat exchange with the high-temperature refrigerant flowing in the radiator 6, the temperature of the waste water in the waste water tank 4 gradually increases, and the heat radiation capability of the waste water to the refrigerant in the radiator 6 gradually decreases. So when the temperature in the waste water tank 4 rises to a certain degree, the water drain solenoid valve 13 needs to be controlled by the master controller to be electrified so as to drain the waste water after the temperature rise in the waste water tank 4 through the floor drain 20. In this way, the waste water after the temperature rise in the waste water tank 4 can be discharged at regular time through the water discharge electromagnetic valve 13 so as to ensure that the waste water tank 4 can replace the waste water in time.

As shown in fig. 1, in some embodiments, the under-kitchen water making system further comprises a second temperature detector 14 provided in the wastewater tank 4, the second temperature detector 14 being used for detecting the temperature of the wastewater in the wastewater tank 4. The second temperature detector 14 is electrically connected with the master controller, and generates a third signal when the second temperature detector 14 in the waste water tank detects that the water temperature exceeds a third temperature threshold; the overall controller controls the energization of the drain solenoid valve 13 upon receiving the third signal. The second temperature detector 14 can monitor the temperature of the wastewater in the wastewater tank 4 at any time to ensure that the wastewater after the temperature rise in the wastewater tank 4 is discharged in time.

As shown in fig. 1, in some embodiments, the under-kitchen water making system further comprises a first water level detector 18 and a three-way valve 19. The first water level detector 18 and the three-way valve 19 are also electrically connected to the overall controller, respectively.

The water inlet of the three-way valve 19 is communicated with the waste water outlet of the filtering piece 3 through the waste water valve 22, the first water outlet of the three-way valve 19 is communicated with the water inlet of the waste water tank 4, and the second water outlet of the three-way valve 19 is communicated with the floor drain 20. The three-way valve 19 can be used for conducting the wastewater outlet of the filter element 3 and the floor drain 20 when being electrified; the three-way valve 19 can be connected with the waste water outlet of the filter element 3 and the water inlet of the waste water tank 4 when the power is off.

A first water level detector 18 is provided in the wastewater tank 4 for detecting the water level of the wastewater in the wastewater tank 4 and sending a fourth signal or a fifth signal to the overall controller.

Specifically, when the first water level detector 18 detects that the water level of the wastewater in the wastewater tank 4 is lower than the tank body lowest water level threshold value, a fourth signal is sent to the master controller, and the master controller receives the fourth signal and then controls the water discharge electromagnetic valve 13 to be powered off and the three-way valve 19 to be powered off respectively.

When the first water level detector 18 detects that the water level of the wastewater in the wastewater tank 4 is higher than the tank body highest water level threshold value, a fifth signal is sent to the master controller, the master controller can control the three-way valve 19 to be electrified after receiving the fifth signal, and at the moment, the wastewater discharged by the filtering piece 3 can be directly discharged through the floor drain 20.

By the cooperation of the first water level detector 18 and the three-way valve 19, it can be ensured that the waste water filtered by the filter element 3 can timely enter the waste water tank 4.

As shown in fig. 1, in some embodiments, the water inlet of the filter 3 is communicated with the water source 16 through the booster pump 15, a water inlet electromagnetic valve 21 is arranged on a pipeline of the booster pump 15 communicated with the water source 16, and the connection and disconnection of the booster pump 15 and the water source 16 can be controlled through the water inlet electromagnetic valve 21.

Further, the kitchen water preparation system further comprises a second water level detector 17 arranged in the clean water tank 1, and the second water level detector 17 and the booster pump 15 are respectively and electrically connected with the master controller. The second water level detector 17 is for detecting the water level in the fresh water tank 1 and is capable of sending a sixth signal and a seventh signal to the overall controller.

Specifically, when the second water level detector 17 detects that the water level in the clean water tank 1 is higher than the tank body maximum water level threshold, a sixth signal can be generated, and the main controller turns off the booster pump 15 when receiving the sixth signal, thereby stopping the supply of pure water into the clean water tank 1; when the second water level detector 17 detects that the water level in the fresh water tank 1 is lower than the tank body lowest water level threshold value, a seventh signal can be generated, and the total controller turns on the booster pump 15 when receiving the seventh signal, thereby continuing to introduce pure water into the fresh water tank 1. This ensures that water is always present in the fresh water tank 1 and the cold water tank 2 by means of the second water level detector 17.
