Among the figure: housing 1, water supply connector 2, water out adapter 3, heating courage 4, control mainboard 5, accurate intelligent water flow regulating device 6, stepper motor 6a, driving gear 6b, adjusting water valve 6c, sector gear 6d, relief valve 6e, inflow temperature sensor 7, leaving water temperature sensor 8, water ga(u)ge 9.
The specific embodiment
Consult Fig. 1 to shown in Figure 3; A kind of electric heater that has intelligence adjusting discharge function of the utility model; Comprise housing 1, on housing 1, be provided with water supply connector 2 and water out adapter 3, in housing 1, be provided with heating courage 4 and control mainboard 5 that mutual circuit connects; Described water supply connector 2 is connected with heating courage 4 pipelines respectively with water out adapter 3; On water supply connector 2 and the pipeline of heating between the courage 4, be provided with accurate intelligent water flow regulating device 6, this accurate intelligent water flow regulating device 6 mainly by stepper motor 6a, be arranged on driving gear 6b on the stepper motor 6a power output shaft, regulate water valve 6c and forms with the sector gear 6d that regulates the interlock of water valve 6c spool, described adjusting water valve 6c is arranged on water supply connector 2 and heats on the pipeline between the courage 4; Described stepper motor 6a is connected with control mainboard 5 circuit; Described driving gear 6b and sector gear 6d engagement are provided with relief valve 6e on adjusting water valve 6c, relief valve 6e is integrated overall structure with regulating water valve 6c; The pressure relief opening of relief valve 6e can draining when convenient and hydraulic pressure is too high over against the through hole of housing 1.In water supply connector 2, be provided with inflow temperature sensor 7; Described water out adapter 3 is provided with leaving water temperature sensor 8; Inflow temperature sensor 7 is connected with control mainboard 5 circuit respectively with leaving water temperature sensor 8.Simultaneously; On the pipeline between heating courage 4 and the accurate intelligent water flow regulating device 6, be provided with water ga(u)ge 9; Water ga(u)ge 9 is connected with control mainboard 5 circuit, and accurate intelligent water flow regulating device 6 is installed in before the water ga(u)ge 9, can detect the big few of discharge so in real time.
The silicon controlled voltage that control mainboard 5 heats on courage 4 water inlet ends through discharge size, Inlet and outlet water temperature sensor temperature value size, the control of real-time detection water ga(u)ge realizes that the power of heater reaches constant leaving water temperature; Suppose that inflow temperature or discharge change; After control mainboard 5 detects signal; Silicon controlled voltage is regulated, make leaving water temperature reach the temperature of constant temperature all the time at once.Suppose that inflow temperature is too low or whose flow is too big, or operating voltage is too low, the leaving water temperature of setting is too high; Cause rated power to satisfy not constant design temperature, appearance temperature is sometimes hot and sometimes cold, at this moment controls mainboard 5 and detects leaving water temperature and do not reach design temperature; Can start 6 work of accurate intelligent water flow regulating device at once; Rotate drive driving gear 6b through control step motor 6a, driving gear 6b drives sector gear 6d and drives the valve core rotation of regulating on the water valve 6c, turns water down thereby make the turning cylinder of regulating water valve 6c control water valve; Control mainboard 5 is the velocity of rotation of control step motor 6a precisely; The angular accuracy that rotates reaches ± and 0.1 °, so precisely the size of current is controlled in fast and stable control, makes the leaving water temperature fast and stable reach the temperature of setting.If supposing inflow temperature raises; Or operating voltage is higher, and the leaving water temperature of setting is low excessively, causes rated power can satisfy constant design temperature; At this moment control mainboard 5 and can start 6 work of accurate intelligent water flow regulating device at once; Rotate through control step motor 6a, realize that in like manner the turning cylinder control of control and regulation water valve 6c is big the water accent, make water yield bigger.
During work; Running water enters into along pipeline through water supply connector 2 and regulates water valve 6c and water ga(u)ge 9, and arrive at last and heat courage 4, and then along pipeline from water out adapter 3; Control mainboard 5 detects water ga(u)ge 9 has current out-of-date, and system can start 4 heating of heating courage automatically.If water feeding pressure is fluctuated, control mainboard 5 at this moment can accurate intelligent ground the size of adjusting current.If discharge is excessive or inflow temperature is low excessively, system can turn current down through stepper motor 6a automatically; If discharge is too small or design temperature reduces, system can transfer current big through stepper motor 6a automatically.No matter regulate and how to change, can reach constant leaving water temperature through accurate intelligent water flow regulating device 6.
