The beneficial effects of the utility model are: it has adopted the hot water circuit control device, it comprises a casing, water return pipeline, the inside of described casing is set up and is divided into two spaces up and down, external circulating backwater inlet, cold water inlet, three interfaces of cold-water return outlet reserved in the lower space bottom of casing; Described water return pipeline is arranged on the lower space of casing, and wherein main line two ends are connecting circulating backwater ingress interface, cold-water return discharge coupling respectively, is connected with in turn between circulating backwater inlet, cold-water return outlet and loops back water pump and check-valves; Connect a bye-pass in the cold-water return of ining succession exports the main line of an end, the other end of described bye-pass is connecting cold water inlet, is provided with a check-valves in bye-pass; Upper space at casing has the program board that is provided with programme regulator for temperature and program timer, program board links to each other with power line and is connected with the guidance panel and a transformer of the casing upper space that coexists respectively simultaneously, the power control terminal of program board is connected with the described power control terminal that loops back water pump, is provided with the temperature sensor that links to each other with program board at the circulating backwater arrival end.So a kind of hot water circuit control device is simple in structure, it is easy to operate to use, energy-conserving and environment-protective, possess regularly functions such as start-stop program, anti-water pump locking defencive function, anti-frost protection function, the demonstration of cooling-water temperature sensor fault of water temperature sensing control, four sections simultaneously, fully takes into account the requirement of user to comfortableness and water saving aspect.
Description of drawings
Fig. 1 is the novel structure principle chart of this use;
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, see shown in the accompanying drawing 1, the hot water circuit control device, it comprises a casing, water return pipeline, the inside of described casing is set up and is divided into two spaces up and down, at external circulating backwater ingress interface 1, cold water inlet interface 2, the cold-water return discharge coupling 3 reserved in the lower space bottom of casing; Described water return pipeline is arranged on the lower space of casing, and wherein a main line 7 two ends are connecting circulating backwater ingress interface 1, cold-water return discharge coupling 3 respectively, is connected with in turn at main line 7 and loops back water pump 4 and check-valves 5; Be connected with a bye-pass 6 in cold-water return exports the main line 7 of an end, the other end of described bye-pass 6 is connecting cold water inlet, is provided with a check-valves 5 in bye-pass 6; Upper space at casing has the program board 8 that is provided with programme regulator for temperature and program timer, program board 8 links to each other with power line 11 and is connected with the guidance panel 9 and a transformer 10 of the casing upper space that coexists respectively simultaneously, the power control terminal of program board 8 is connected with the described power control terminal that loops back water pump 4, is provided with the temperature sensor 12 that links to each other with program board 8 at the circulating backwater arrival end.
Its method of operating respectively passes in and out water valve for opening hot water cyclesystem earlier, and the socket of connecting with the mains turns on the power switch again, and machine will enter running status automatically, thereby can reach the work of hot water cyclesystem according to the timing routine that user's needs are set or stop.
