Description
Technical field
The utility model relates to a kind of electric heater, particularly relates to a kind of electric heater of the comprehensive human electric shock's of preventing injures and deaths.
Background technology
At present, that the power supply of electric heater is all adopted is alternating current 220V 50Hz, by the design of I appliances.Usually electric heater causes the reason of electric shock accidents that three aspects are arranged: first aspect comes from water heater itself; The long-term use of electrothermal tube in the water-heater water tank caused the fatigue of metal surface, will break when arriving its limit, causes heating wire and water to be connected; The voltage of 220V directly forms path through the current and the human body of flowing through over the ground; A large amount of electric currents will cause the permanent damage of heart through human body when the electric current that surpasses 50mA is flowed through heart, even dead immediately.Second aspect is when earthed system is unusual (earth resistance be above standard more greatly regulation); When particularly earthed system lost efficacy (obstructed with the earth); It just becomes 0 type of water heater; And the protection against electric shock of 0 type of water heater will depend on environment, and such water heater is placed on and uses in the bathroom, can not protection against electric shock be provided with environment.The third aspect is that ground wire itself is charged, and water heater itself mostly has good earth connection, and the eliminating of its leak current fault just relies on good ground connection; Receive it tired but water heater was counter when local tape was electric; Cause electric shock equally, above-mentioned all accidents occur repeatedly for many years, and are too numerous to enumerate.And the most frequently used anticreep mode of present electric heater all adopts earth leakage protective device, when leakage current surpasses 10mA, in 0.1s, cuts off the electricity supply automatically, guarantees user's security; Yet it is malfunctioning or when damaging, the user is using hot water, just has big electric current (especially high-power water heater) through human body, and causing death's accident takes place when earth leakage protective device.
In order to solve this some problems; The applicant has proposed a kind of new design concept; Concrete employing measure is: the one, utilize big or small " the Living water electric-resistivity method " of water resistance restriction leakage current; The built-in water resistor assembly of promptly in entery and delivery port, packing into, the leakage current that makes be less than 5mA, thereby guarantee user's life safety.In addition, the metal section and part that simultaneously human bodies such as exposed urceolus of electric heater is prone to touch is designed with the structure of II appliances.
The utility model content
The purpose of the utility model is the weak point to above-mentioned prior art, and a kind of electric heater of the safe comprehensive human electric shock's of preventing injures and deaths is provided.
The purpose of the utility model realizes through following technical proposals:
A kind of comprehensive electric heater that prevents human electric shock's injures and deaths; Comprise urceolus; The inner bag of mounting strap inner bag link plate seat in the urceolus; Link plate is arranged on outer drum outer wall, and the position of corresponding electrical control part is provided with service ports on the urceolus, and water inlet member, water outlet part are installed in water heater water inlet, delivery port position through the insulation tube joint respectively; Be provided with insulated enclosure pad and insulated enclosure cover between insulation tube joint and water inlet member, the water outlet part;
Said water inlet member is the flanged dish of being processed by insulating materials of an end; The cylindrical tube of other end shutoff insulating plug; Be provided with dividing plate in the cylindrical tube its endoporus is separated into U-shaped flowing water passage; (r is a tee section equivalent redius in the flowing water passage to flowing water passage length
, unit: cm);
The cylindrical tube of said water outlet part for processing by insulating materials; The flowing water passage is arranged in it; (r is a tee section equivalent redius in the flowing water passage to flowing water passage length
, unit: cm);
Service ports place on the urceolus is provided with insulating lid;
Inner bag link plate seat A face is installed insulation nut sleeve assembly, and the B face is installed insulating cell;
Be filled with ambroin pad and thermal insulating layer between inner bag and the urceolus; And no lead is communicated with between inner bag and the urceolus, and inner bag reliably is connected with the ground wire of the power line of band creepage protection function.
Further, said urceolus, inner bag, link plate are fixedly connected through Steel Bolt.
Further, said insulation nut sleeve assembly is made up of insulation holder and metal nuts.
Further, the wall thickness of said insulation holder and insulating cell all is not less than 1mm.
The operation principle of the utility model is:
When the direct short circuit of 220V 50Hz alternating current that uses acted on the water heater, in order to guarantee specified alternating voltage 220v power supply down, the maximum leakage electric current was less than 5mA.Resistance R water=220V/5mA=44 * 10 of running water
3Ω; The electricalresistivity of running water=1250 ± 50 Ω cm; If getting the flowing water passage length is L, the tee section equivalent redius is r in the flowing water passage.Then,
.Therefore; As long as the length
of the flowing water passage of water inlet member, water outlet part; Just can satisfy water heater maximum leakage electric current less than 5mA; And overlap connection at entery and delivery port with insulation tube joint, insulated enclosure pad, insulated enclosure and draw water heater; Pipeline structure adopts damping, just can guarantee water resistance limits leakage current size, guarantees user's security.
The beneficial effect of the utility model is: the metal section and part that the human bodies such as exposed urceolus of electric heater are prone to touch is designed with the structure of II appliances; Inner bag has I appliances structural design.The omnibearing solution in the inner bag because of charged in the heat-generating pipe electric leakage causes water, or, shower person is brought the technical problem of electric shock injures and deaths (injury) because of ground wire electrification, earthed system lost efficacy, this electric heater use is safer.
