Also comprise emergency stop switch, be arranged on the guidance panel and be connected on the control loop of main control unit, cut off the electricity supply when this emergency stop switch is pressed.
The utility model, outlet pipe and water inlet pipe be ground connection respectively, and the delivery port place of outlet pipe is provided with water flow sensing unit, also be provided with detection of electrical leakage module and leakage sensor, control by micro computer, under the combination of multiple safety measure, improved the security of products energy greatly.
Description of drawings
Fig. 1 is an internal structure schematic diagram of the present utility model;
Fig. 2 is an external structure schematic diagram of the present utility model;
Fig. 3 is circuit theory diagrams of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As Fig. 1, Fig. 2 and shown in Figure 3; the utility model comprises shell 12 and is arranged on water inlet pipe 8, outlet pipe 3, heating unit 5 and control module 4 in the shell 12; described outlet pipe 3 and water inlet pipe 8 be ground connection respectively; because all unearthed the causing of getting an electric shock takes place in most of electric heaters; the utility model water inlet and delivery port all with the earth excellent contact, even if product electric leakage or water source electric leakage also can protect the user not encroached on by ground connection.Described heating unit 5 is connected between water inlet pipe 8 and the outlet pipe 3.Described control module comprises main control unit, water flow sensing unit 1, temperature sensor 2, two overheat protectors 6, detection of electrical leakage module and leakage sensors 9; Water flow sensing unit 1 is arranged on the delivery port place of outlet pipe 3, when water flow sensing unit 1 has detected water-flow signal, send and detect water-flow signal to main control unit and start heating unit 5 and begin heating, if there is not the water heating unit 5 that flows then not work, not only saved the energy but also can avoid that heater block is empty under anhydrous situation to be burnt and cause damaging; Temperature sensor 2 is arranged on the delivery port place of outlet pipe 3, and temperature sensor 2 detects coolant-temperature gage and this temperature value is passed to main control unit, and main control unit is adjusted the heating power of heating unit according to this temperature value.Described overheat protector 6 is arranged on the heating unit 5 and is connected in the control loop of main control unit, cuts off the electricity supply when the temperature of heating unit 5 surpasses setting value.The detection of electrical leakage module comprises sensor for detecting electric leakage, and this sensor for detecting electric leakage is connected on the inlet wire of power line, sends electric leakage signal to main control unit and cut off the electricity supply when sensor for detecting electric leakage detects electric leakage, prevents that the user from getting an electric shock; Leakage sensor 9 is arranged on the below of heating unit 5, and when machine intimate had water to leak into, leakage sensor 9 sent signal to the main control unit that leaks and cuts off the electricity supply and report to the police, with the unnecessary loss that prevents to cause owing to leaking.Outlet pipe 3 also adopts the anti-electric wall design of Haier, under the situation that above-mentioned proof and electric leakage-proof safety all lost efficacy, also has anti-this heavy protection of electric wall.
Shell of the present utility model is provided with guidance panel, which is provided with induction type button 10, LCDs 11 and emergency stop switch 13, induction type button 10 and LCDs 11 are connected to main control unit respectively, because the button on the open market all is a thin film switch, time has been grown, breakage of thin film applied may cause to leak and cause getting an electric shock, and the induction type button just can be realized, and button is that whole nonconducting glass or ambroin are made very wear-resisting as long as bump gently.Emergency stop switch 13 is connected on the control loop of main control unit; under the situation that above-mentioned defencive function all lost efficacy; general machine only removes the external gate of total lock of powered-down or water heater; this gate is not often in the bathroom; in case of emergency the time is just crucial; the utility model is provided with a waterproof emergency stop switch 13 on guidance panel, press this emergency stop switch 13 and can all cut off live wire, ground wire automatically.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
