Detailed description of the invention
It is more fully understood that essence of the present utility model, below in conjunction with the accompanying drawings for convenience of those skilled in the art Detailed description of the invention of the present utility model is described in detail.
Embodiment one
As it is shown in figure 1, a kind of constant temp gas water heater, including: gas heater body 1, it is connected to Circulating line 2 on gas heater body 1, and the circulating device 3 being arranged on circulating line 2;It is special 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.
Embodiment two
As shown in Figure 4, a kind of constant temp gas water heater that the present embodiment provides, its structure and embodiment one Basically identical, difference is:
Described circulating device 3 includes: connect pipeline 3-1, be arranged on the circulating pump 3-2 connected on pipeline 3-1, Temperature sensor (not shown), switchable first cross valve 3-6 and switchable second cross valve 3-7, described first cross valve 3-6, the second cross valve 3-7 connect the two ends of circulating pump 3-2, a controller respectively 3-4 is connected with temperature sensor, the first cross valve 3-6, the second cross valve 3-7 signal;Controller 3-4 is according to temperature The signal of degree sensor feedback controls the first cross valve 3-6, the second cross valve 3-7 switching turns to and realizes circulating device 3 in the conversion rotated forward between loop module and reverse cycle module.
Compared with embodiment one, the present embodiment only need to change the conducting direction of two cross valves, right Circulating pump does not has particular/special requirement, is applicable to various circulating pump, does not has the circulating pump reversion resistance of start big yet Problem, is effectively improved the service life of circulating device.
Embodiment three
As it is shown in figure 5, a kind of constant temp gas water heater that the present embodiment provides, its structure and embodiment one Basically identical, difference is:
Described circulating device 3 includes: connect pipeline 3-1, is arranged on the temperature sensing connected on pipeline 3-1 Device (not shown), the first circulating pump 3-8 and the first stop valve 3-9, the first circulating pump 3-8 and the first stop valve 3-9 Constitute forward circulation module, be parallel with the second circulating pump 3-10 and the second stop valve at the two ends of forward circulation module The installation direction of installation direction the first circulating pump 3-8 of 3-11, the second circulating pump 3-10 is contrary, the second circulating pump 3-10 and the second stop valve 3-11 constitute recycled back module, a controller 3-4 and described temperature sensor, just Connecting to loop module, recycled back module by signal, controller 3-4 is according to the signal control of temperature sensor feedback Forward circulation module processed or the work of recycled back module, it is achieved circulating device is followed in rotating forward loop module and reversion Conversion between ring module.
Specific works principle is: in circulation warm, when temperature sensor detects return water temperature TBackwaterLess than design temperature TSetTime, start the first circulating pump 3-8 by controller 3-4 and make the first stop valve 3-9 Conducting makes the second stop valve 3-11 block, and carries out forward circulation, and now water heater detects that current are opened by signal Dynamic combustion heat heating.When temperature sensor detects return water temperature TBackwaterReach setting value TSetTime, feed back to immediately Controller 3-4, controller 3-4 control the first circulating pump 3-8 and stop, starting the second circulating pump 3-10 and make first Stop valve 3-9 blocks and makes the second stop valve 3-11 conducting, carries out recycled back, and now, water flow of water heater amount passes Sensor can't detect water-flow signal (output of non-water flow signal), and water heater stops the heating of water but still keeps water Circulation, the second circulating pump run the time not less than the 1/3 of the first pump operating cycle time, thus may be used To reach the purpose of mixed water, make in circulating line even water temperature everywhere constant.
Essence of the present utility model has been described in detail by above detailed description of the invention, but can not be with Protection domain of the present utility model is limited by this.It should be evident that opening in this utility model essence Under showing, the art those of ordinary skill also can carry out many improvement and modification, it should be noted that this A little improvement and modification all fall within claims of the present utility model.
