The specific embodiment
See also Fig. 1 and Fig. 2, the invention provides a kind of water heater with rate of flow of water valve assembly, be provided with a rate of flow of water valve assembly 1 in this water heater, rate of flow of water valve assembly 1 is arranged on the water-supply-pipe 2 of gas heater, and rate of flow of water valve assembly 1 can be arranged at cold water end (water intake end) or the hot water end (water side) of water heater and locate.This water heater includes a blower fan 3, a burner 4 and a heat exchanger 5 in addition, and burner 4 is arranged between blower fan 3 and the heat exchanger 5.Burner 4 can make cold water can enter heat exchanger 5 and carry out heat exchange in order to reheat heat exchanger 5, and row is discharged the hot water use again.In the place, water side of water heater one leaving water temperature detector 7 is set in addition, in order to detect leaving water temperature, in the water intake end place of water heater one flow rate detector 8 is set in addition, in order to detect rate of flow of water.In addition, also an entry temperature detector 6 can be set in the water intake end place of water heater, in order to detect into coolant-temperature gage.
See also Fig. 2, rate of flow of water valve assembly 1 comprises a motor 11 and is connected in a control valve 12 of motor 11, and motor 11 can be the motor of stepper motor or other patterns, and this motor 11 is stepper motor in the present embodiment.Motor 11 has one can be in order to the output 111 of outputting rotary power, and motor 11 is electrically connected at suitable drive circuit (figure slightly), can utilize digital form or other mode CD-ROM drive motors 11.When CD-ROM drive motor 11 actions, its output 111 gets final product transmission control valve 12, in order to utilize the aperture of motor 11 control and regulation valves 12, uses the adjusting rate of flow of water.
During CD-ROM drive motor 11, output 111 can rotate by transmission control valve main shaft 124, because control valve main shaft 124 is bolted in first supporting seat 122, therefore can make control valve main shaft 124 produce axial displacement by threaded function, approach or away from valve opening 1214 in order to interlock valve body 1242, use the aperture of control valve opening 1214, make the aperture of valve opening 1214 can diminish or become big.
See also Fig. 1 and Fig. 3, the invention provides a kind of control method with water heater of rate of flow of water valve assembly, one rate of flow of water valve assembly 1 is set in this water heater, and the place, water side in water heater arranges a leaving water temperature detector 7, in the water intake end place of water heater one flow rate detector 8 is set; This water heater is by factory settings one allowable temperature deviation dT and design a minimum rate of flow of water Qs, and this allowable temperature deviation dT can set in response to different demands, can be set at ± 0.3 to 1 ℃, for example can be set at ± 0.3 ℃, ± 0.5 ℃ or ± 1 ℃ etc.; This control method comprises that step is as follows:
At first, water heater is carried out general running control, and detect heat outputting coolant-temperature gage T2 with leaving water temperature detector 7, detect actual rate of flow of water Qa with flow rate detector 8, set hot water temperature Ts by the user in addition; This running control refers to general utilize the MCU control module to carry out digital control of using of water heater;
Then, judge that whether (heat outputting coolant-temperature gage T2-sets hot water temperature Ts) be greater than allowable temperature deviation dT, if, judge whether standard-sized sheet of rate of flow of water valve assembly 1 again, if rate of flow of water valve assembly 1 is standard-sized sheet not, then amplify the output rate of flow of water by rate of flow of water valve assembly 1, the control step that then turns round again continues follow-up step; If rate of flow of water valve assembly 1 is standard-sized sheet, the control step that then directly turns round again continues follow-up step;
If (heat outputting coolant-temperature gage T2-sets hot water temperature Ts) is non-greater than allowable temperature deviation dT, judge then that then whether (setting hot water temperature Ts-heat outputting coolant-temperature gage T2) be greater than allowable temperature deviation dT, if, judge that more whether (the minimum rate of flow of water Qs of actual rate of flow of water Qa-) be less than 0, if, the control step that then turns round again continues follow-up step; If (the minimum rate of flow of water Qs of actual rate of flow of water Qa-) is non-less than 0, then dwindle the output rate of flow of water by rate of flow of water valve assembly 1, the control step that then turns round again continues follow-up step;
If (setting hot water temperature Ts-heat outputting coolant-temperature gage T2) is non-greater than allowable temperature deviation dT, the control step that then turns round again continues follow-up step, stops until the user till the use of water heater.
Water heater of the present invention is by rate of flow of water valve assembly 1 control rate of flow of water, is provided with leaving water temperature detector 7 in order to detect leaving water temperature in the place, water side of water heater in addition, is provided with flow rate detector 8 in order to detect rate of flow of water in the water intake end place of water heater in addition.Therefore the present invention's aperture that can regulate rate of flow of water valve assembly 1 in preferable mode automatically, by this, the present invention has water heater and the control method thereof of rate of flow of water valve assembly, can the water temperature in summer and winter be changed, accurate control water yield, reaching keeping of hot water temperature, and can increase the adjusting range of water temperature and rate of flow of water.
When the firepower maximum, when leaving water temperature does not reach design temperature, can start current limit function, reach design temperature to improve leaving water temperature.At high temperature season, go into coolant-temperature gage when high, then can open more rate of flow of water, be better than traditional flow-limiting valve.
Only the above only is preferred embodiment of the present invention; non-ly be intended to limit to Patent right requirement protection domain of the present invention; so the equivalence of using specification of the present invention and graphic content to do such as changes, and all in like manner all is contained in the claim protection domain of the present invention, closes and gives Chen Ming.
