Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As it is shown in figure 1, the external circulation preheating of a kind of heater and thermostatic electric water heater, including shell 1, water storage liner 2, set
Put the end cap 3 in water storage liner 1 one end open, heater 4, circuit board 5, tap water water inlet pipe 6 and constant-temperature effluent pipe 7.
Also include water pump 8, thermostatic valve 9, the motor 10 driving thermostatic valve 9 and water pump threeway 12,
Arranging cold water inlet hole and hot water effluent hole on described end cap 3, cold water inlet hole is arranged on the lower section in hot water effluent hole；
Straight tube one end of water pump threeway 12 connects with cold inlet opening, the other end connects with water pump 8 water inlet end, the water side of water pump 8
Connect with the water inlet end of heater 4；The arm of water pump threeway 12 connects with tap water water inlet pipe 6；
Thermostatic valve 9 one water inlet interface 91 connects with hot water effluent hole, another water inlet interface 92 connects with the water side of heater 4；
The mixing water water outlet mouthpiece of thermostatic valve 4 and constant-temperature effluent pipe 7；
Thermostatic valve 9, water pump 8, motor 10 are connected with circuit board 5 respectively.
In this enforcement, when cold water inlet hole and hot water effluent hole are provided with end cap 3, as horizontal use.
Can also be water storage liner 2 length direction and horizontal plane, cold water inlet hole and hot water effluent hole be arranged on storage
On water inner bag 2, as vertical use.
Described tap water water inlet pipe 6 is provided with flow transducer 61, and described water pump threeway 12 is provided with temperature sensor
121, the water inlet interface 92 that described thermostatic valve 9 is connected with heater 4 is provided with temperature sensor 11, on described constant-temperature effluent pipe 7
Being provided with temperature sensor 71, described water storage bag 2 is provided with temperature sensor 21.
As in figure 2 it is shown, when needing to preheat the water in water storage liner 2, water pump 8 works, the water in water storage liner 2, through cold
