Levying and be, described circulating device 3 includes forward circulation module and recycled back module, the fluid in circulating line
Under forward circulation module effect forward circulation or under the effect of recycled back module recycled back.
As in figure 2 it is shown, described circulating device 3 includes: connect pipeline 3-1, it is arranged on connection pipeline 3-1
On can carry out the circulating pump 3-2 of rotating, temperature sensor 3-3, and with circulating pump 3-2, temperature sensor
The controller 3-4 that 3-3 signal connects;The signal that controller 3-4 feeds back according to temperature sensor 3-3 controls circulating pump
3-2 forward or reverse, to realize circulating device 3 in the conversion rotated forward between loop module and reverse cycle module.
For preferably storing and performing corresponding control command, controller 3-4 connects and has instruction module
3-5, controller 3-4 control circulating pump 3-2 by instruction module 3-5 after identifying the signal that temperature sensor 3-3 feeds back
Forward or reverse.
As it is shown on figure 3, in circulation warm, when temperature sensor 3-3 detects return water temperature TBackwater
Less than design temperature TSetTime, start circulating pump 3-2 by controller 3-4, carry out forward circulation (rotating forward), this
Time water heater detect current pass through signal enabling combustion heat heating.When temperature sensor detects return water temperature TBackwater
Reach setting value TSetTime, feed back to controller 3-4, controller 3-4 immediately and make circulating pump by instruction module 3-5
3-2 recycled back (inverts), and now, water flow of water heater quantity sensor can't detect water-flow signal, and (non-water flow is believed
Number output), water heater stops the heating of water but still keeps the circulation of water, thus can reach the mesh of mixed water
, make in circulating line even water temperature everywhere constant.For ensureing the uniformity of mixed water, circulating pump reversion runs
Time is not less than the 1/3 of the rotating forward time.
A kind of constant temp gas water heater that the present embodiment provides, can by being built-in with one in circulating device
The water circulating pump that regulation turns to, to change the direction of circulating water flow, thus accurately controls constant temp gas water heater
Opening and closing, make water heater economical operation in warm reasonable;Pre-heat effect reaches optimal, overcomes
The functional deficiency of existing independent loops device.Meanwhile, circulating device comprise controller, temperature sensor,
Circulating pump, its control mode not only can accurate constant temperature, also there is forward circulation and start water heater, recycled back
Do not start the antifreeze function in the case of water heater two kinds.
