Abstract
The invention discloses an electric water heater which belongs to the technical field of electronic information. 1, Carbon (graphite) is used as an electrode, and an alternating current direct flowing water mode is used for heating. The phenomenon that a power supply is connected first and then a water valve is opened, so electricity is wasted is avoided, and once boiling is caused by too small water flow, the service life is influenced; and 2, one or more interception grids are arranged at any position of a pipeline, the interception grids can be earth wire grids, zero line grids or mixed grids, the interception effect of each grid is related to various factors, such as the position where the grid is, the shape of the grid, internal resistance and external resistance the in the pipeline and the like, and the grids are sequentially arranged on the middle points of the corresponding sections. The two grids are both arranged in the middle of a spray pipe, and after 220-V alternating current passes through two grids by the limited spray pipe, voltage and current both tend to be zero.
Description
One. technical field:
Electronic information field.
Two. background (original) technology
1, adopt magnesium or silicon to do anode, the AC-DC snead process also has the resistance wire formula to exchange the indirect method.
2, have only the ground connection insurance to be connected on metal shell or the water tank; Have establish the electric leakage safety valve the electric wall of setting up defences also arranged.
3,, zero, live wire all adopts monoblock type patch method.
4, jet pipe is very long, and resistance value is very big.
5, easily dry combustion method and damage utensil need be done to take precautions against and handle.
6, energy saving is different, and sheathing material is different, be afraid of to impact, and the cost height, volume is bigger or huge, and the complex structure life-span is not waited, and has electronics to show, uses running water and civilian 220V alternating current.
(numerous doubtful points of original technology and corresponding solution)
1, zero line (neutral conductor) ground connection is the major hidden danger that constitutes unsafe factor, the underfooting that is to say everyone stepping on constantly one or more can hairtrigger electrode, when certain position of human body touched other any one electrode and associated conductor, constituting the loop can discharge.If high pressure can produce shock hazard.The most effective solution is exactly the earth connection of cancellation zero line, and making zero line no longer is the neutral conductor.From then on human body can be away from that specious so-called neutral electrode, even human body touches some electrodes and conductor can not cause discharge yet like this, otherwise any safety devices all will be challenged.(the present invention can not solve question of substance, just proposes recommendation on improvement and relative some its danger coefficients of reduction.See summary 3,2)
2, original technology is owing to adopt ground, zero, fiery Trinity patch, be difficult to guarantee that under the situation that live wire is connected it (should be repeatedly to open circuit that ground wire and zero line do not open circuit, this point frequently appears having proved in electric spark in the process of inserting and pulling out of latch, can cause tripping operation when the magnetic valve accumulation of energy reaches certain magnitude, energy shortage also can cause self-induction).In case open circuit, self induction electromotive force will act directly on the human body lacking under ground wire and the zero line situation as protection by jet pipe or shell or latch, particularly safety valve generation take-off because its self-induction action makes voltage rise De Genggao.One opens self induction voltage and electric current can raise tens times simultaneously to hundreds of times, and this phenomenon is more common.If the two poles of the earth interaction, the phase place stack can make voltage and current raise ten thousand times suddenly, according to electrical power fundamental relation formula p=U
2/ R=I
2R can produce extra-high voltage more than 1,000,000 volts 10,000 times the time when voltage raises, and its danger coefficient (power factor) be this 1,000,000 square! The field energy that also has electromagnetic field in addition ... shock hazard is that moment takes place under these circumstances mostly.Therefore, ground connection and connecting to neutral line are very important.(the present invention has solved this problem basically, sees summary 2,3.Cardinal principle is that electromagnetic energy can bypass and reduce terminal voltage more fully indirectly)
3, with regard to electric leakage safety valve performance, also exist the contradiction that self is difficult to overcome.If highly sensitive easy take-off, the former is an advantage, and the latter is shortcoming (because existence of self induction electromotive force); On the contrary, sensitivity is low to be difficult for take-off, will produce the problem opposite with the front again.In addition, be about in the of 0.2 second effective discharge time of the take-off time of safety valve and shock hazard, and the two is identical substantially in time, and safety valve has not only become unnecessary ornaments like this, the arch-criminal's (the present invention has solved this problem basically, sees summary 3,2) who has often served as incident.Should have only electronic type electric leakage safety valve and overload relief valve still effectively.The electronic type safety valve is subjected to the restriction of electric current again, and overload relief valve still exists inductance.
4, most safety valves comprise that most electric brakees are that live wire and zero line cut off simultaneously when cutting off the electricity supply, supply voltage and self induction electromotive force are directly pointed to the earth under the situation that zero line interrupts like this, and human body has often served as this middle conductor just, so shock hazard has produced.(the present invention has solved this problem basically, sees summary 3,2)
5, original electric heater complex structure involves great expense, and most consumers are hung back; Also have long jet pipe, huge body, people have faced the fearful with no fears.(the present invention has solved this problem basically, sees the technology of the present invention feature 5,6)
Three. summary of the invention
1, does electrode with carbon (graphite), exchange direct continuous-flow type heating.
2, adding the interception grid, can be one, several or multi-joint, can be located at each position in the pipeline.Can be the ground wiregrating, also can be zero line grid or mixing grid.The interception result of each grid is relevant with the various factors such as internal resistance extrernal resistance of its residing position, shape, pipeline.And each grid should be located on the mid point that the highway section should be arranged successively.
The present invention establishes grid two altogether, all is located at the centre of jet pipe.The alternating current of 220V by limited jet pipe again behind these two grid voltage and current all go to zero.
3, ground connection connecting to neutral line adopts fixed permanent wiring, has only live wire to adopt patch.
4, adopt the Fuse Type wire to bear the overload insurance, the safety valve class is not essential.
