Abstract
The utility model relates to an electric shock prevention electric heater, which comprises an electric heater body, and a water inlet and a water outlet, which are arranged on the electric heater body, and is characterized in that a discharge component allowing water current to pass through is arranged on the water outlet, and the discharge component is connected with a protective grounding wire or a protective zero line in commercial power. Compared with the prior art, the electric heater has the advantages that phase voltage carried by water after heated is eliminated through being directly guided in the protective grounding wire or the protective zero line after passing through the discharge component, because the discharge component is arranged on the water inlet or the water outlet on the electric heater body, and is connected with the protective grounding wire or the protective zero line in commercial power, thereby eliminating any phase voltage in water flowing from the water outlet of the electric heater, and water without phase voltage can be used safely by people without electric shock phenomenon.
Description
Technical field
The utility model relates to a kind of protection against electric shock electric heater.
Background technology
At present, most existing protection against electric shock electric heater, it is commonly used, and the technical scheme of being taked that prevents to get an electric shock has: (1) all is made as insulation tube with water inlet pipe and outlet pipe; (2) with the length of outlet pipe lengthening with the increase flow route, the outlet pipe elongated portion is tortuous distribution the in the electric heater body then; (3) in the electric heater body interior special-purpose " Fang Dianqiang " device is set;
For example application number is that the Chinese invention patent " electric-shock-proof quick-heating electric water heater " of 200610009128.X is exactly to adopt above-mentioned (1), next the preventing of (2) scheme to get an electric shock; But the cost of this way is the length that must increase outlet pipe, and then in the tortuous distribution of electric heater body, such way will certainly increase the volume of electric heater body to the outlet pipe elongated portion; And application number to be 200310120897.3 Chinese invention patent " the general electricity-preventing wall device of monolithic processor controlled wall-body standard socket " be exactly adopts preventing that above-mentioned (3) scheme comes to get an electric shock, and adopt " electricity-preventing wall device ", its structure is comparatively complicated, cost is also higher, and the rust particle contamination when not reaching enough purity or running water at conveyance conduit, running water is arranged, thereby make the tap water quality variation, the conductance of water increases, and this " electricity-preventing wall device " may be difficult to play a role.
In addition, the electric shock phenomenon of electric heater all is because phase voltage electric leakage meeting or water make water have phase voltage in through electrical heating wire heating or electric arc heated process, this water that has phase voltage flows to gondola water faucet through delivery port and is used by the people, if the phase voltage that exists in the water is too high, will produce the electric shock phenomenon.
The utility model content
Technical problem to be solved in the utility model provides a kind of water that flows out from the electric heater delivery port and does not have phase voltage, the effective safe protection against electric shock electric heater of protection against electric shock.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this protection against electric shock electric heater; comprise the electric heater body and be arranged on water inlet and delivery port on this electric heater body; it is characterized in that: described delivery port place is provided with the discharge part that stream flows through that can supply water, and should discharge part links to each other with protection ground wire or protection zero line in the civil power.
Described discharge part can be the conductive filament of a helical form horn-type structure, and the horn mouth of this trumpet type conductive filament enlarges gradually along water (flow) direction.
Described discharge part can also be made other version, promptly described discharge part one mosquito-repellent incense type conductive filament, and the face of this mosquito-repellent incense type conductive filament is perpendicular to the water (flow) direction setting.
Described discharge part also can be a type conductive filament, and the face of this time type conductive filament is perpendicular to the water (flow) direction setting.
Except above-mentioned two kinds of versions, described discharge part can also be a conductive plate, be provided with the apopore that at least one supplies water and flows out in the middle of this conductive plate, and the face of this conductive plate is perpendicular to the water (flow) direction setting.
Like this; the water that has phase voltage is through delivery port the time; because the filtration of discharge part has been arranged; just make the phase voltage in the water directly import on the protection ground wire or protection zero line in the civil power via conductive filament or conductive plate; thereby make the water that flows out the electric heater delivery port no longer have any phase voltage; when people do not have the water of phase voltage in use, be perfectly safe, can not have the electric shock phenomenon.
Certainly, safer for the use that makes electric heater, described water inlet also can be provided with above-mentioned discharge part, and protection ground wire or protection zero line are linked to each other.
Compared with prior art; advantage of the present utility model is: install the discharge part by water inlet on the electric heater body or delivery port place; and protection ground wire or protection zero line are linked to each other; this directly imports after via the discharge part on protection ground wire or the protection zero line and eliminates with regard to making through the phase voltage of carrying in the water of heating back; thereby make the water that flows out the electric heater delivery port no longer have any phase voltage; when people do not have the water of phase voltage in use; be perfectly safe, can not have the electric shock phenomenon.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Protection against electric shock electric heater shown in Fig. 1～2; it comprises electric heater body 1 and is arranged on water inlet 11 and delivery port 12 on this electric heater body; be connected with attaching plug 13 on the electric heater body 1; delivery port 12 places are provided with the discharge part 2 that the stream that can supply water flows through, and protection ground wire or protection zero line link to each other in should discharge part 2 and civil power.
Discharge part 2 can be made multiple version:
Embodiment one: referring to shown in Figure 3, discharge part 2 is the conductive filament of a helical form horn-type structure, and the horn mouth of this trumpet type conductive filament enlarges gradually along water (flow) direction.This structure has the good phase voltage property eliminated, because water in process of flowing, can produce to circle round, can well eliminate the phase voltage of carrying in the water clean by the conductive filament of helical form trumpet type; This conductive filament can be made by nichrome, has good rustless property.
