The electric heater unit 10 connects, as the control center of the whole device.
Wherein, first shut-off valve 2, second shut-off valve 3 are all normally opened shut-off valve, and first branch pipe 4 is close
The water inlet end of the circulating line 1 is arranged, and second branch pipe 5 is arranged close to the water outlet of the circulating line 1, the drying
Frame 6 includes the drying pipe of several rows parallel connection, and the electric heater unit 10 is the electric heating tube being disposed therein in a drying pipe.
In the present embodiment, the preferably described circulating line 1, first branch pipe 4 and second branch pipe 5 are together with molding
Integral structure.It is preferred that being detachable structure between the stoving rack 6 and first branch pipe 4, second branch pipe 5, preferably
The circulating line 1, the master controller 11 are all mounted on an apparatus main body 12, and the preferably described master controller 11 adds with the electricity
It is connected by aviation plug 13 between thermal 10, to waterproof, anticreep.
In conjunction with shown in Fig. 2, when practical application, hot water circulating device is mounted on to the distalmost end water spot of gas heater 17
Place 14,14 hot water pipeline 15 is connect with the water inlet end of the circulating line 1 at distalmost end water spot, 14 at distalmost end water spot
Cold water pipes 16 connect with the water outlet of the circulating line 1., must be electric by controlling second shut-off valve 3 in work, it will
14 cold water pipes 16 are separated with the hot water pipeline 15 at the distalmost end water spot, prevent cold water from the cold water pipe
Road 16 flows into the hot water pipeline 15, while also thoroughly solving to open cold water water heater startup phenomenon.
In conjunction with shown in Fig. 3, hot water circulating device provided in this embodiment has the function of to preheat and dries two kinds, in the master
Operation display is connected on controller 11, on the operation display be equipped with preheating button, drying button, heating button and
Cooling button.
1) pre- hot function：Booting is powered on for the first time, after opening pre- hot function, if what the temperature sensor 9 detected
Temperature value T meets T<T sets-Δ T, and the master controller 11 is then opened the DC speed-changing water pump 7 and operated with maximum (top) speed, hot water
Device works, and is heated to water temperature；When meeting T>When T sets -1 DEG C, first shut-off valve 2 maintains a normally open, second cut-off
Valve 3 obtains electric closure, and the DC speed-changing water pump 7 shuts down, and hot water pipeline and cold water pipes are completely separated at this time.Wherein, T is set
For the preheating temperature of setting, Δ T is system return difference, general value 5-10K.T is set, Δ T is stored in master controller 11, and value can
Think and preset, or from main regulation.
2) drying function：After opening drying function, if the temperature T that the temperature sensor 9 detects meets T<T
When drying -10 DEG C, first shut-off valve 2, second shut-off valve 3 obtain electric closure, open 7 Half Speed of the DC speed-changing water pump fortune
Turn, while master controller 11 controls the electric heater unit 10 by relay and heated, and fast implements at the stoving rack 6
Object drying and heating, until T>When T dries+10 DEG C, the electric heater unit 10 stops heating.Wherein, T dries the baking for setting
Dry temperature adjusts drying temperature T by the button that heats up, cooling button and dries, and T bakings are configured between 60-80 DEG C.
After drying function use, user thinks to carry out domestic water immediately, need to exclude the high temperature at the stoving rack 6
Water.High-temperature water method for removing is：Long-press dries button 3s, and first shut-off valve 2,3 dead electricity of the second shut-off valve keep normal
It opens, the DC speed-changing water pump 7 operates, and user opens tap and can quickly remove high-temperature water drainage, significantly promotes user's body
Test sense.
The full speed of the DC speed-changing water pump 7, half-speed operation can realize that the water flow is passed by controlling driving current
The water flow that sensor 8 is fed back can be used as DC speed-changing water pump 7 at full speed, the check value of half-speed operation.
As a kind of transformation embodiment of the present embodiment, the hot water circulating device can also be installed commonly without heating tube
Stoving rack, using recirculated water water temperature also have certain heating effect.
As another transformation embodiment of the present embodiment, when user is tangible without using drying function or installation environment
It is limited, first branch pipe 4 and second branch pipe 5 can be connected by conventional hoses 18, as shown in Figure 4, it can be achieved that
The pre- hot function of cycle of system.
From the foregoing description of structures and principles it should be understood by those skilled in the art that, the utility model
It is not limited to above-mentioned specific implementation mode, it is equal using the improvement of techniques well known and replacement on the basis of the utility model
It falls in the scope of protection of the utility model, the scope of protection of the utility model should be limited by each claim and its equivalent
It.
