Abstract
The invention discloses a safe insulating wall used for an electric water heater, which comprises a water inlet (1), a water outlet (2), a casing body (3) and a water flow passage (4) and is characterized in that the water flow passage adopts a labyrinth passage. The water flow passage is formed through respective passages of an upper, a middle and a lower labyrinth plates being overlapped. The insulating wall effectively solves the personnel safety problem when the electric water heater is current leaking, and has the advantages of low cost and convenient disassembly and assembly.
Description
[technical field]
What the present invention relates to is a kind of annex of electric heater, and what be specifically related to is a kind of anti-creeping safe electricity-isolation wall.
[background technology]
Electric heater is a kind of universal household electrical appliance, and it brings great convenience for people's life, but electrical equipment can leak electricity unavoidably, and electric heater is no exception, and how can also protect personal safety when electric heater leaks electricity is the problem that people are concerned about always.The electric heater that can more effectively address this problem in the market, the inner anti-torch of installing of this water heater, anti-torch is connected on the electric heater delivery port, and this anti-torch is an elongated flexible tube, there are into water, water out adapter in the flexible pipe two ends, are exactly water stream channel in the middle of the flexible pipe; Be vulnerable to damage for the solution flexible pipe is installed in electric heater, connect a Stainless Steel pipe at hose overcoat.Should prevent that torch was less because of its aquaporin cross-sectional area, route is long, and water resistance is bigger, has both made electric leakage, the water that flows out is not with forceful electric power yet, but the electric heater inner space is limited, is with the anti-torch limited length of Stainless Steel pipe, (it is the longest to be 490mm so the length of its aquaporin is also limited, model is 0040501492), and owing to be installed in electric heater inside, so dismounting is also inconvenient.
[summary of the invention]
In view of the problem that present known technology exists, the technical problem to be solved in the present invention is to be to provide that a kind of anticreeping power is strong, cost is low, the safe electricity-isolation wall for electrical water heater of easy accessibility.
For solving the problems of the technologies described above, the present invention takes following technical scheme to finish:
A kind of safe electricity-isolation wall for electrical water heater comprises water inlet, delivery port, housing, water stream channel, it is characterized in that: described water stream channel is a kind of labyrinth passage.Described water stream channel by labyrinth, upper, middle and lower plate separately passage be formed by stacking.Adopt between gland with described delivery port and the housing and be threaded.
Because this safe electricity-isolation wall for electrical water heater has adopted the labyrinth type water stream channel, so this electricity-isolation wall in very little volume range, has very long water stream channel.Under the identical situation of aquaporin cross-sectional area, route is long more, and water resistance is big more, resistance electric energy power is strong more, and this electricity-isolation wall just can increase water stream channel length under the very little situation of profile like this, when water heater leaks electricity, effectively reduce leakage current, guarantee personal safety.This electricity-isolation wall profile is small and exquisite, be installed in electric heater outside and export with electric heater and be connected, and this electricity-isolation wall delivery port is located on the gland, and gland and electricity-isolation wall housing are with being threaded, and cost is low so this electricity-isolation wall has again, the advantage of easy accessibility.

[specific embodiment]
Accompanying drawing has been represented technical scheme of the present invention and embodiment, further describes each relevant details and operation principle thereof of embodiment below more in conjunction with the accompanying drawings.
With reference to accompanying drawing 1, this safe electricity-isolation wall for electrical water heater comprises housing 3, gland 8, labyrinth, upper, middle and lower plate 5,6,7, one end of described housing is provided with water inlet 1, after superposeing successively, labyrinth, described upper, middle and lower plate is pressed in the cavity of housing, the other end of described housing and described gland are with being threaded, gland is provided with delivery port 2, by labyrinth, upper, middle and lower plate separately passage be interconnected and constitute labyrinth type water stream channel 4 together.Be provided with sealing ring between housing, gland and the labyrinth plate.
With reference to accompanying drawing, when electric heater uses, water flows into electricity-isolation wall water inlet 1 from the water heater delivery port, enter the cavity 9 of labyrinth plate 5, on the process labyrinth plate labyrinth shape water stream channel 4 back from export 10 enter the cavity 11 of labyrinth plate 6, through in labyrinth plate labyrinth shape water stream channel 4 back from exporting 12 cavitys 13 that enter down labyrinth plate 7, through entering electricity-isolation wall delivery port 2 from exporting 14 behind the labyrinth plate labyrinth shape water stream channel 4 down, flow out electricity-isolation wall subsequently, its water stream channel length overall is 610mm, after testing: the 220V alternating current is directly led to the electric heater inner chamber, the water that flows out by this electricity-isolation wall, leakage current decays to below the 0.18mA gradually, is lower than the leakage current standard of national GB4706.11 regulation, has guaranteed personal safety.This electricity-isolation wall profile is small and exquisite, be installed in electric heater outside and export with electric heater and be connected, and this electricity-isolation wall delivery port is located on the gland, and gland and electricity-isolation wall housing are with being threaded, and cost is low so this electricity-isolation wall has again, the advantage of easy accessibility.
In sum, adopt the safe electricity-isolation wall for electrical water heater of technique scheme, anticreeping power is strong, profile is small and exquisite, cost is low, easy accessibility, will be subjected to users' welcome.
Claims (3)
