The fluid heater comprises the electric shock prevention heating structure. Accordingly, the fluid inlet and the fluid outlet are zero voltage ends which are safe for users all the time, and the electric safety performance is improved greatly.
Description
Technical field
The utility model relates to a kind of fluid technical field of heating, relates in particular to a kind of protection against electric shock heating arrangement of fluid heater.
Background technology
Fluid heater such as treasured under quick electric water heater, double-mode electric water heater, instant electric tap, the platform, since plug and play, the instantaneous hot fluid that adds; Power is big than conventional storage-type electric water heater; And the general volume of above-mentioned fluid heater is less, in order to improve electrical safety performance; Can the fluid passage of certain distance be set in fluid heater, thereby utilize the resistance of fluid to come decay current and reach the effect of preventing electric wall.
But; Also there is defective in this kind structure, because the two ends of electric heating element connect the live wire and the zero line of power supply respectively, so the fluid intake of fluid heater or export one of them and inevitable be connected with the live wire of power supply; Because live wire is a high voltage, so there are high voltage in fluid intake or outlet.The fluid intake of fluid heater, outlet all are provided with earth connection, and general resident's electrical network all has earth connection, even if leakage of current also can lead away with the electrical network ground wire, so can be not dangerous to the person.Yet; Possibly there is not earth connection in part grown-ups and children district or its electrical network of interim simple and easy residence; Have only zero line and live wire, if fluid heater because the distance of fluid passage Leakage Current not enough or that other reasons causes is bigger than normal, electric current will flow through human body gets an electric shock the people.
The utility model content
To the electrical safety performance problem that above-mentioned fluid heater exists, the utility model provides a kind of protection against electric shock heating arrangement, and it can improve electrical safety performance, guarantees user's personal safety.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is following: a kind of protection against electric shock heating arrangement, comprise fluid passage, electric heating element, and said electric heating element is arranged in the fluid passage; Said fluid passage comprises fluid intake and fluid issuing; Said electric heating element is arranged between fluid intake and the fluid issuing, it is characterized in that, is provided with zero-potential point in the said fluid passage; Said electric heating element is near an end electric connection of power supply live wire of zero-potential point, electric heating element other end electric connection of power supply zero line.
Preferable, the zero line binding post is set in the said fluid passage, said zero line binding post is electrically connected with zero-power line.
Preferable, said zero line binding post is arranged between fluid intake and the electric heating element and closes on the position of electric heating element.
The utility model also provides a kind of fluid heater, and it can improve electrical safety performance, guarantees that the user's is safe in utilization.The technical scheme that the utility model fluid heater adopts is following: a kind of fluid heater is characterized in that said fluid heater comprises the described protection against electric shock heating arrangement of above-mentioned arbitrary technical scheme.
Compared with prior art, the beneficial effect of the utility model is:
Electric heating element is near an end electric connection of power supply live wire of zero-potential point in the utility model; And then longshore current body flow direction; The voltage distribution is zero-power line end, power firestreak end, zero-potential point successively in the fluid passage; Or be zero-potential point, power firestreak end, zero-power line end successively, that is fluid intake, fluid issuing be the no-voltage end of guaranteeing user's personal safety all the time, improved electrical safety performance greatly.
Preferable, the zero line binding post is set in the said fluid passage, said zero line binding post is electrically connected with zero-power line, and so, this zero line binding post is zero-potential point.
Preferable, said zero line binding post is arranged between electric heating element and the fluid intake and closes on the position of electric heating element.So; Even the user has connect anti-power firestreak, zero line, make this zero line binding post become high voltage, but owing to this zero line binding post is arranged between electric heating element and the fluid intake; Fluid passage distance between this electric heating element and the fluid issuing does not change; Be the attenuation also not variation of fluid, therefore, also can not cause electrical safety performance to reduce even connect instead to electric current.
Description of drawings
Fig. 1 is the utility model protection against electric shock heating arrangement one embodiment sketch map.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the technical scheme of the utility model is done further explanation.
Embodiment one
With reference to figure 1, a kind of protection against electric shock heating arrangement comprises fluid passage 4, electric heating element 3; Said electric heating element 3 is arranged in the fluid passage 4, and said fluid passage 4 comprises fluid intake 1 and fluid issuing 2, and said electric heating element 3 is arranged between fluid intake 1 and the fluid issuing 2; It is characterized in that; Be provided with zero-potential point in the said fluid passage 4, said electric heating element 3 is near an end 31 electric connection of power supply live wires 7 of zero-potential point, electric heating element 3 other ends 32 electric connection of power supply zero lines 8.
In the present embodiment, in the said fluid passage 4 zero line binding post 6 is set, said zero line binding post 6 is electrically connected with zero-power line 8, and so, this zero line binding post 6 is zero-potential point.Certainly, also can otherwise in fluid passage 4, zero-potential point be set, repeat no more at this.Said zero line binding post 6 is arranged between electric heating element 3 and the fluid intake 1 and closes on the position of electric heating element 3.So; Even the user has connect anti-power firestreak 7, zero line 8, make this zero line binding post 6 become high voltage, but owing to this zero line binding post 6 is arranged between electric heating element 3 and the fluid intake 1; Fluid passage distance between this electric heating element 3 and the fluid issuing 2 does not change; Be the attenuation also not variation of fluid, therefore, also can not cause the substantive reduction of electrical safety performance even connect instead to electric current.
Certainly; The protection against electric shock heating arrangement of the foregoing description one also can be applicable under quick electric water heater, double-mode electric water heater, instant electric tap, the platform in the fluid heater such as treasured, and said fluid heater comprises the described protection against electric shock heating arrangement of above-mentioned arbitrary technical scheme.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art, under the prerequisite that does not break away from the utility model principle, can do the improvement of some suitable actual conditions to the technical scheme of utility model.Therefore, the protection domain of the utility model is not limited thereto, and those of skill in the art are any to be included within the utility model protection domain based on non-material change on the utility model technical scheme.
