Description
Technical field
The invention belongs to electric heater art, be specifically related to the Electrical Safety device of electric heater.
Background technology
Current various electric heater adopts leakage switch and Anti-leakage circuit, electric heater ground connection is relied on to solve protection against electric shock problem, if user's earth connection is bad or ground connection open circuit or earth connection charged, although electric heater itself is qualified, user in use still also exists hidden danger.If electric leakage itself, adds again the nonstandard problem of above-mentioned earth connection during water heater uses, water safety is just difficult to ensure.
The producer had at present adopts water resistance method to share electrical leakage voltage, and the increase realizing current resistance value by lengthening water flow passage makes it to meet anticreep requirement, ensures that human body is not shocked by electricity.What have is contained in heat storage water tank by the insulation inlet tube and outlet tube of lengthening, and what have is installed at the water-in and water-out insulation tube of lengthening between mixed water valve and water heater intake-outlet, all has certain effect.But first method is difficult to realize for the quick-heating electric water heater that heating water tank is very little.Water resistance is installed between water heater import and mixed water valve pretty troublesome by second method.Two kinds of methods are also difficult to install additional for a large amount of quick-heating electric water heaters in use.Therefore had dealer to invent spiral water flow passage, mosquito-repellent incense formula water flow passage etc., but spiral water flow passage structure exists volume, and excessive being unfavorable for installs, and mosquito-repellent incense formula water flow passage hazard rate is higher, and manufacturing cost is high.
Summary of the invention
In order to overcome above-mentioned defect; the invention provides a kind of electric shock preventing protector of electric water heater; this electric shock preventing protector of electric water heater makes it to meet anticreep requirement by the increase lengthening water flow passage and realize current resistance value, and reliability is high, again and structure is simple, easy to implement.
The present invention in order to the technical scheme solving its technical problem and adopt is:
A kind of electric shock preventing protector of electric water heater, comprise insulation upper cover, insulation lower cover and some layers of insulation water-trough plate, the both ends of the surface of every layer of described insulation water-trough plate one of at least on be formed with one group of current deflecting structure, insulation upper cover, insulation lower cover and some layers of insulation water-trough plate and on current deflecting structure be jointly defined as runner;
Often organize described current deflecting structure as follows: the end face of insulation water-trough plate is provided with the water channel wall of some circles independently ring-type, except outmost turns water channel wall, all the other respectively enclose water channel wall and all disconnect and have two terminations, face water channel wall with people to be as the criterion, in a clockwise direction these two terminations are defined as head end and tail end, each circle water channel wall is sorted diametrically from inside to outside successively, be tightly connected between the head end of the outer ring water channel wall that the head end of innermost circle water channel wall is adjacent with it, be tightly connected between the tail end of adjacent odd item water channel wall, be tightly connected between the head end of neighbouring even-numbered item water channel wall,
The delivery port of insulation upper cover communicates with the water inlet end of adjacent current deflecting structure, and the water side of upper water flow guide structure communicates with the water inlet end of adjacent lower current deflecting structure, and the water inlet of insulation lower cover communicates with the water side of adjacent current deflecting structure.
Current enter the current deflecting structure in insulation water-trough plate by the upper cover that insulate, and in current deflecting structure, the water (flow) direction of adjacent channels is not same direction but the flowing in rightabout.The sectional area of runner and length are effectively guaranteed when utensil occurs that electric leakage is abnormal, and under the discharge and electrical conductivity condition of regulation, the leakage current that actual user may touch is less than electric heater country respective standard, guarantees use safety.Certainly, from said structure, current also can be entered the current deflecting structure in insulation water-trough plate by insulation lower cover, namely above-mentioned all water outlets all can be changed into into water, and all water inlets all can be changed into water outlet, and effect is the same.
Further technical scheme of the present invention is:
Often organize described current deflecting structure as follows: between the head end of the outer ring water channel wall that the head end of innermost circle water channel wall is adjacent with it, be sealedly connected with the first partition wall, the water inlet end of current deflecting structure is (when current are entered by the lower cover that insulate, this water inlet end has also just become water side) be opened in described first partition wall place, be tightly connected by the first partition wall between the head end of the i.e. outer ring water channel wall that the head end of innermost circle water channel wall is adjacent with it, first partition wall shape is determined as required, current are by the first partition wall ingoing stream guide frame, second partition wall is sealedly connected with respectively between the tail end of adjacent odd item water channel wall, be tightly connected by second partition wall between the tail end of i.e. adjacent odd item water channel wall, some second partition walls can be connected and also can not be connected, and the second partition wall shape is determined as required, the 3rd partition wall is sealedly connected with respectively between the head end of neighbouring even-numbered item water channel wall, be tightly connected by the 3rd partition wall between the head end of i.e. neighbouring even-numbered item water channel wall, some 3rd partition walls can be connected and also can not be connected, and the 3rd partition wall shape is determined as required.
