Circulating electromagnetic valve 6 and tap water supply magnetic valve 16 are automatically turned on, municipal water supply is introduced in water tank 4；When level sensor 9 is visited
When measuring in water tank 4 water level and being equal to or more than water level highest limit value, system is automatically switched off circulating electromagnetic valve 6 and tap water supply electricity
Magnet valve 16, stops to the water filling of water tank 4.
As shown in figure 3, the circulation waterway 3 is used for the temperature of water body in control loop, keeps user to take out at any time and set
The frozen water of constant temperature degree, and water body is long placed in without breed bacteria in preventing loop.Specifically, being provided with temperature on the circulation waterway 3
Degree sensor 8, the temperature sensor 8 is arranged on the bottom of household freezer 18 and refrigerating box 19, is followed when temperature sensor 8 is detected
When water temperature in ring water route 3 is higher than temperature limit, system automatic circulating electromagnetic valve 6 and water pump 5 are continuous by water pump 5
Pump water so that the water circulation in whole loop is behaved；Water body in temperature sensor 8 detects circulation waterway 3 is low
When temperature limit, system automatic detection circulating electromagnetic valve 6 and water pump 5 are that then system is automatically switched off and follows after opening
Ring magnetic valve 6 and water pump 5.
One of preferred scheme as the technical program, the function water route is also equipped with the junction of circulation waterway 3
Flowmeter 10, when function water route single exceedes single water limit value with water, system is automatically switched off water pump 5 and function water route
Control magnetic valve 13.The setting of the flowmeter 10 so that the water consumption in loop is measured and counted, prevents from disposably taking
Dilutional hyponatremia, causes water pump 5 to dally.
The function water route, including but not limited to drinking-water water route and ice making water route, can be one of them in specific implementation
Or other devices of whole, or the interior water of refrigerator.Specifically, so that drinking-water water route and ice making water route are installed in refrigerator simultaneously
As a example by, the drinking-water water route and ice making water route are installed by controlling the connection flow gauge 10 of magnetic valve 13, the flowmeter 10 respectively
In function water route and the junction of circulation waterway.
As shown in figure 4, the ice making water route includes ice machine 14, when using, open ice machine 14 and switch, control magnetic valve
13 are triggered simultaneously, and system automatically turns on water pump 5, and the water body Automatic water-filling water route 17 in water tank 4 is injected into ice making through circulation waterway 3
In the ice machine 14 in water route, when the single of flowmeter 10 counts water injection rate exceedes setting value, system is automatically switched off control electromagnetism
Valve 13 and water pump 5.
As shown in figure 5, the drinking-water water route is arranged on drinking-water feed water inlet 11, the drink away from one end of control magnetic valve 13
The inner side of water feed water inlet 11 is provided with drinking-water magnetic valve 12, when user opens drinks taps, while triggering drinking water electromagnetism
Valve 12 is opened, and system automatically turns on water pump, and the water body in drinking-water water route is flowed out by feed water inlet 11 of drinking water.
Wherein, when single counts water injection rate is no more than the setting value upper limit of flowmeter 10, opened by manually closing drinking water
Close, and triggering is drunk water solenoid valve 12 and is closed, system is automatically switched off water pump 5；Exceed flowmeter 10 when single counts water injection rate
During the setting value upper limit, system is automatically switched off drinks water solenoid valve 12 and water pump 5.
Meanwhile, as one of the preferred scheme of the technical program, can in systems set the opening time for drinking taps
The upper limit, when the opening time for drinking taps exceedes setting time, system control is drunk water solenoid valve 12 and is closed, and water pump 5 is closed,
Prevent from drinking taps because client forgets to turn off, caused by safety problem and waste water source problem.
One of preferred scheme as the technical program, wherein, filter 7 is additionally provided with the water filling water route, it is described
The water body in water filling water route is installed via circulation waterway 3, the function water route is flowed into after filter 7 with the junction in water filling water route 17
There is the non-return valve 15 for preventing running water to be directly entered function water route, the tap water supply magnetic valve 16 is connected to the He of non-return valve 15
Between circulating electromagnetic valve 6.Filter 7 setting cause loop in water body every time circulation can purifying water body, meanwhile, filtering
The cooperation of device 7 and flowmeter 10, can with the filtering water body total amount of statistic filter 7, and with the filtering water body according to filter 7
Higher limit compares, and notifies that user changes filter in time.
Present invention also offers a kind of refrigerator, the refrigerator water path control system with above-mentioned automatic circulation water-supplying.
In sum, the water filling water route of automatic circulation water-supplying, keep loop water temperature circulation waterway and with flow
The function water route of meter so that the loop in refrigerator keeps constantly circulation and purifies；The mouthfeel of Chilled Drinking Water is kept, and prevents user
Forget to turn off switch and once the fetching water water pump that mostly occurs to dally for a long time the too high problem burnt of occurrence temperature, while reminding user
Filter is changed, with safety and stability higher.
Know-why of the invention is described above in association with specific embodiment.These descriptions are intended merely to explain of the invention
Principle, and can not by any way be construed to limiting the scope of the invention.Based on explanation herein, the technology of this area
