Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for the utility model is described, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of electric hot water tap, comprise pedestal 1, Discharging bent-tube 2 and water supply connector 3, the outer wall of described pedestal 1 is provided with spool fitting seat 4, spool fitting seat 4 inside are provided with spool 5, the outer end of spool 5 is fixing by valve gap 6, the right side of spool 5 is provided with the handle 7 be fixed on spool fixed base 4, the inside of handle 7 is provided with annular boss 8, the bottom of described pedestal 1 arranges water supply connector 3, the inside of pedestal 1 is provided with circuit board 9, the bottom of circuit board 9 is provided with sensitive switch 10 near the right-hand member place, the right-hand member of sensitive switch 10 is provided with the push rod 11 be in contact with it, push rod 11 is respectively through spool fixed base 4 and valve gap 6, the exposed outside at valve gap 6 of the right-hand member of push rod 11, pedestal 1 inside in described spool 5 left sides is provided with intake tunnel, the left end of intake tunnel is provided with flow rotor 12, pedestal 1 inside of flow rotor 12 1 sides is provided with Hall transducer 13, the bottom of flow rotor 12 is fixed on pedestal 1 by radiating copper nut 14, the contacting point of the bottom of flow rotor 12 and radiating copper nut 14 is provided with stainless shot 15, the bottom of radiating copper nut 14 is provided with the controllable silicon 16 be connected with circuit board 9, be provided with the heating unit 17 be connected with circuit board 9 in the pedestal 1 of flow rotor 12 tops, the top of described pedestal 1 is provided with bend pipe base 18, the top of bend pipe base 18 connects Discharging bent-tube 2, bend pipe base 18 outsides are fixed on pedestal 1 outer wall by upper cover 19.
Electric hot water tap of the present utility model, the outer wall of described push rod 11 is provided with spring 20, and an end of spring 20 is resisted against on spool fixed base 4, and the other end of spring 20 is provided with the back-up ring 21 be fixed on push rod 11 outer walls, and the right side of back-up ring 21 is resisted against on valve gap 6.
Electric hot water tap of the present utility model, described radiating copper nut 14 passes through seal with O ring with the contacting point of pedestal 1.
Electric hot water tap of the present utility model; the inside of described heating unit 17 is provided with thermel protection device; thermel protection device comprises that the thermistor 23 and the Thermal Cutoffs 24 that are encapsulated in successively from top to bottom Stainless Steel Tube 22 inside form; Stainless Steel Tube 22 is fixed on pedestal; the bottom of Stainless Steel Tube 22 is provided with two tenminal blocks 25 that are connected with Thermal Cutoffs 24 with thermistor 23 respectively, and tenminal block 25 is electrically connected to circuit board 9.
Electric hot water tap of the present utility model, the inside of described bend pipe base 18 is provided with the pressure release passage be communicated with pedestal 1 internal cavities, is provided with silica gel plug 26 in pressure release passage, and pedestal 1 outer wall in bend pipe base 18 outsides is provided with the relief hole 27 be communicated with pressure release passage.
Electric hot water tap of the present utility model is when concrete the use, when handle forwards the hot water gear to, the annular boss jack-up push rod of handle inside, make the contact of sensitive switch by jack-up, and then trigger energising, heating unit is started working, when handle forwards the cold water gear to, push rod breaks away from the annular boss in handle, and push rod leaves the contact of sensitive switch under the effect of spring, and circuit disconnects immediately.During the current direction flow rotor in intake tunnel, the flow rotor rotates and produces electromagnetic pulse signal in addition, and after Hall transducer is sensed signal, conduction, to circuit board, starts in order to control water tap.When handle is got to the cold water gear, spool is closed the current that lead to the flow rotor direction immediately, and the flow rotor stops operating, and Hall transducer is not sensed electromagnetic pulse signal, and the water tap of circuit board control immediately stops heating.Solved the problem that traditional glued membrane Starting mode causes the heating unit mistake to start because of water freezing or other reasons, two kinds of Starting mode combinations, even wherein a kind of starting drive breaks down and also can not cause machine Automatic-heating to occur.In heating unit dry combustion method or pedestal, during excess Temperature, thermistor can pass to circuit board to signal, and circuit board can be regulated the working state of heating unit automatically.When thermistor is out of control or other situations while causing in pedestal temperature still out of control, Thermal Cutoffs can activate outage in time, plays ultimate protection, and outage speed is fast, highly sensitive.It is little that thermistor adds the thermel protection device volume that the temperature safety fuse cutout is combined into, and can not take in a large number in the electric hot water tap control unit original with regard to limited small space.
Under normal state, water is discharged to outside from Discharging bent-tube in addition, and now the silica gel plug is to fill on the bend pipe base.When the Discharging bent-tube water outlet is caused draining at need by the other reasons such as freeze of the water in foreign matters from being blocked or Discharging bent-tube, hydraulic pressure increase in pedestal causes the silica gel plug to be extruded in the hole of bend pipe base, water is taken advantage of a situation by being discharged into outside in relief hole, so just can solve the problem that causes the machine blast because the pedestal internal pressure is excessive, the silica gel plug can be stayed in little space, relief hole top, need only again stifled going back after fixing a breakdown, compare with traditional Decompression valves, simple in structure, cost is low, easy for installation.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
