Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model embodiment is described further:
As shown in the figure, a kind of electric hot water tap of band safety detection, it includes the tap water inlet pipe mouth 1 being sequentially connected with, it is placed in the valve member in housing 2 and the water discharge of water faucet mouth of pipe 3, constitute one between described housing 2 and valve member and accommodate chamber, described housing 2 surface is provided with the handle 4 opened and closed for control valve door assembly, and with accommodate the hole 5 that connects, chamber, it is provided with safety detection assembly, it includes heater circuit, test point and detection piece, human body 10 contacts test point, human body 10 contacts with ground GND simultaneously, therefore a complete loops is constituted, if there being electric leakage, detection piece can send prompting, now user can substantially learn that this faucet is in leakage condition；If in the case of power supply does not has good earth, power firestreak L and zero-power line N to connect instead, detection piece also can send prompting, and now user can substantially learn that this faucet is in unsafe condition；And when zero-power line N and a ground GND at least loose contact, detection piece also can send prompting, now uses this electric hot water tap to be in unsafe condition, can avoid the generation of danger in time.
Described detection piece uses neon big gun 6, and described test point uses induction coil 7, and described housing 2 surface is provided with and accommodates the hole 5 that chamber connects; described neon big gun 6 is placed in hole 5, and described induction coil 7 is close to edge, hole 5 and is arranged, and is connected with heater circuit by neon big gun 6; induction coil is used to do test point; easy to use, use neon big gun 6 to do detection piece, point out exception by luminescence; the most eye-catching; it is easy to user and perceives abnormal conditions in time, take protective measure, be truly realized safe water.
Described heater circuit includes hydraulic pressure switch K and the heater strip EH being sequentially connected in series between power firestreak L and zero-power line N, neon big gun 6 compresses switch the node between K and heater strip EH through resistance R5 water receiving, neon big gun 6 and induction coil 7 form testing circuit, this circuit is accessed outfan, in order to detect whether electric leakage, and on the premise of detection input power is without good earth, whether power firestreak L and zero-power line N connects the anti-personal safety that may insure that user.
Described heater circuit also includes resistance R1, display lamp HL and diode D1; after the negative pole of described resistance R1, display lamp HL and diode D1 is sequentially connected in series; it is connected in parallel on the two ends of heater strip EH; wherein resistance R1 water receiving compresses switch the node between K and heater strip EH; carry out unidirectional protection with diode D1, carry out, with display lamp HL, the prompting whether heater strip EH works.
Being provided with display window 8 on described housing 2 surface, described display lamp HL is arranged on receiving intracavity, and is shown by this display window 8, this display window 8 uses groove or hole, in order to the brightness of display lamp HL is transmitted, to point out user, the state the most whether faucet heats.
Described valve member includes valve F, and its port 1 is connected with handle 4, handle 4 control to open and close, and port 2 is connected with the water inlet of heater strip EH, and port 3 is connected with hydraulic pressure switch K.Handle 4 goes to hot water end and opens, water inlet has water to initially enter, water one road flows to hydraulic pressure switch K, hydraulic pressure switch is turned on, heater circuit is started working, another road flows to heater strip, by heater strip, water is carried out heating work, make the water discharge of water faucet mouth of pipe 3 can go out hot water, hydraulic pressure switch K damages when can not turn on, heater circuit does not works, therefore the water discharge of water faucet mouth of pipe 3 goes out cold water, open when handle 4 goes to cold water end, water inlet has water to initially enter, flow to heater strip EH, owing to now hydraulic pressure switch K is not turned on, therefore remain cold water after current heated silk EH and flow out from the water discharge of water faucet mouth of pipe 3；Handle 4 is closed, and water inlet stops water inlet, and hydraulic pressure switch K disconnects, and does not also have water to enter back into, the now water discharge of water faucet mouth of pipe 3 no longer water outlet in heater strip.
nullThe outlet of heater strip HE is sequentially connected with the first pipe 91、Second pipe 92、3rd pipe 93，Described 3rd pipe 93 is connected with the water discharge of water faucet mouth of pipe 3，Water resistance R2 in described first pipe 91 is connected in parallel on heater strip EH two ends，After water resistance R3 in described second the pipe 92 and water resistance R4 in described 3rd pipe 93 series connection，Wherein water resistance R2/R3/R4 is the first pipe 91、Second pipe 92、The equivalent resistance of water in 3rd pipe 93，Node between water resistance R2 and water resistance R3 meets zero-power line N，Be equivalent to water resistance R2 and be connected in parallel on heater strip EH two ends，Resistance due to water resistance R2 is much larger than the resistance of heater strip HE，Therefore in the case of parallel shunt，Big electric current can heated silk HE，Small area analysis can be through water resistance R2，Return to zero-power line N end，Thus avoid electric current to flow out through water resistance R3；Further, after water resistance R3/R4 series connection, both node ground connection GND, just in case there being small area analysis to flow out from water resistance R3 end, then now electric current can flow into ground GND through water resistance R3, is further ensured that no current flows through water resistance R4, even if or also electric current, the most also it is the water discharge of water faucet mouth of pipe 3 that the small area analysis that can be the faintest flows through the vacant end of water resistance R4, water resistance R4, so personal safety when guarantee hot water；In addition, according to this circuit, the line if ground GND starts to exchange fire, then neon big gun 6 also can be bright, if when zero-power line N and a ground GND at least loose contact, now certainly having electric current at the node between water resistance R3/R4, this electric current enters ground through neon big gun 6, human body 10, now neon big gun 6 also can be bright, and user can obtain in time now with the unsafe prompting of hot water.
Being only preferred implementation of the present utility model above in association with the embodiment described by accompanying drawing, and not restriction to protection domain of the present utility model, any improvement done based on this utility model spirit all ought to be within this utility model protection domain.
