Description
Technical field
The present invention relates to the device that when a kind of tap of fetching boiling water discharges water, water heater power supply disconnects automatically, is a kind of water heater protective device of wireless induction power-off of impeller power generation integrated formula concretely.
Background technology
At present; water heater is all in anticreep passive protection mode; this mode makes water heater no matter when using or not making; water heater has all remain electricity condition; in time will discharging water; the power line of water heater is still energized with room electricity, brings harm can to like this personal safety of people.
Although, be equipped with the water heater of anti-electricity wall or earth leakage protective device, if desired, needed coupling to have the circuit of earth loop.But substantially, during all house decorations, only have mounting anode and cathode, do not implement the installation of ground wire, like this, even if anti-electricity wall works, but do not have the earial drainage of ground wire, protected effect plays little.At this; some producer just directly draws the circuit of electric leakage and requires that installing master worker is directly fastened on the setscrew of installation water heater, but metope is all ceramic tile and cement; these are all insulators, obviously do not reach due protected effect on insulator fastening for a root guard line.
So water heater lethal news of leaking electricity does not belong to case, in order to avoid this type of accident occurs in succession, needs when user uses hot water, there is the power supply automatically cutting off water heater, to ensure the personal safety of user.
Summary of the invention
The object of the present invention is to provide a kind of water heater protective device of wireless induction power-off of impeller power generation integrated formula, efficiently solve when opening water heater tap and discharging water, the function that power supply can disconnect automatically.
The present invention is achieved through the following technical solutions: a kind of water heater protective device of wireless induction power-off of impeller power generation integrated formula, be made up of acceptance division and emission part, it is characterized in that, emission part is arranged on tube connector, on the water inlet pipe that tube connector is serially connected in water heater or outlet pipe, acceptance division is installed on the electrical connection of wall Shang Yu city or is directly inserted on original socket;
Further, described TRT is arranged on the inside of tube connector, impeller is connected to the outer of magnet steel, power coil is arranged on the inside of magnet steel, power coil is connected with emitter, fetch boiling water tap time, current impeller rotate, the generating of magnet steel cutting power coil, electric energy to be powered and this electric energy is also the reference signal of emitter wireless signal emission to emitter;
Further, have a solenoid and control module in described acceptance division, the output of control module is connected with solenoid, solenoid installs a switch outward, switch one end is connected with socket, and the plug for water heater inserts, and the other end is connected with supply main;
Control module also comprises receiving system, and receiving system makes control module control the conducting of solenoid and cut-out according to the signal of emitter;
The signal that emitter sends by described receiving system passes to control module; the electric energy of control module electric conduction magnetic coil; switch contact disconnects; electric energy is cut off; the water safety of available protecting water heater user, when the signal of emitter stops, control module cuts off the electric energy of solenoid; switch contact resets, water heater recovery heating.
Further, described impeller has 7 ~ 13.
Further, described emission part can also increase MP3 player according to Production requirement, and player is connected with electric supply installation, and the electric energy of this player is taken from self power generation.
Further, described emission part also has keyboard, and described keyboard is connected with control module, and described keyboard has multiple time to set frame, and each time setting frame can only input the time period between two time,
Independent input on each setting frame also sets signal transmission time and the signal dwell time of emitter, and setting is launched and pressed OK button after dwell time, performs this order by control module.
Such as:
1. at left frame 17:00 input time of the first setting frame, right frame input 23:00, so, at 17:00 ~ 23:00 during this period of time, emitter does not transmit, this setting be consider After Hours librarian use time in heat, expense electric energy can not be allowed also to ensure the water temperature of water heater.
2. at left frame 11:00 input time of the first setting frame, right frame input 14:00, at left frame 17:00 input time of the second setting frame, right frame input 23:00, so, in these two section times of 11:00 ~ 14:00 and 17:00 ~ 23:00, emitter does not transmit, this setting is that the old man in considering to get home is accustomed to noon and has a bath, and all the other personnel have a bath at night and can ensure the water temperature of water heater.
The use habit of user of service worked out by all the other setting frames, do not input and do not perform.
That is; within the above-mentioned time period, acceptance division is in the heating of conduction state water heater; simultaneously; in the time period of setting, if tap discharges water, control module preferentially performs this signal; ensure the power-off protection of water discharge of water faucet within the time period of heating; all the other time emitters all send wireless signal, make acceptance division disconnect the connection of water heater and civil power, to reach the object of saving electric energy.
Beneficial effect is:
Efficiently solve when opening water heater tap and discharging water, the function that power supply can disconnect automatically, thus effectively ensure the Electrical Safety of human body.
Utilization of the present invention brings the protection of active safety by solving electric heater user that China market capacity surpasses 200,000,000; the passive protection formed with the earth leakage protective of conventional hot water's device; the active protected mode of its water outlet both power-off has the precedence surmounting passive protection technology in security, and the market demand potential is huge.
