Abstract
The utility model discloses an electricity-proof appliance of the electric water heater. The electric-proof appliance is comprised of an inner tube and an outer covering that are made by the plastic material of high insulating property, temperature resistance, and pressure resistance. Wherein, a spiral wing panel spreads all over the outer cover of the inner tube, and a spiral socket is arranged on the inner wall of the outer covering. In the central part of the upper outer covering is provided with a thread connector with an osculum, and the bottom of the outer covering is covered with an inscription. A rubber sealing ring is positioned between the outer covering and the inscription. The utility model is characterized in that the electrical resistance is high, the resistance power is strong, and the electricity-proof feature is reliable to ensure the customers safety. The utility model is a dual-function in one which is not only an anti-creep carefree appliance, but also an aqua signal or temperature sensor appliance. The utility model lessens effectively the volume of the electric water heater as well as brings down the production cost.
Description
Technical field
A kind of annex of electric heater, especially anti-creeping safety guard.
Background technology
The anticreeper that present various electric heaters are installed exists all that versatility is strong, the weak point of function singleness.Be respectively individual components every electric installation, magnetic switch, temperature sensing device, can only be installed in the electric heater body again, cause the electric heater volume bigger, the manufacturing cost height.
Summary of the invention
The purpose of this utility model provides a kind of electric heater safe electricity-isolation device, accomplishes to prevent effectively electric leakage, can reduce the electric heater volume again, reduces production costs.
Technical scheme is to make inner core and shell with high insulation heat resisting and pressure resisting plastic material, inner core barrel periphery is furnished with the helical form fin, on the outer casing inner wall to helical groove should be arranged, inner core screws in shell and forms spiral channel, straight water channel is arranged at inner core barrel bottom, shell upper has the nipple of apopore in being, connect in the outer casing underpart rotation set has, shell and in be equipped with rubber seal between connecing.All being installed on the electric heater inlet tube and outlet tube of said structure every electrical equipment.Because the spiral channel cross-sectional area is less, route is but very long, and water resistance is very big, both made the electric heater electric leakage, and the water that flows out is not with forceful electric power yet, and the electric current of leakage is dropped to below the safe current index of national regulation.Through overtesting: the 220V alternating current is directly led on electrical equipment front end iron pipe, only be lower than 5 milliamperes weak current through the water that flows out every electrical equipment.
Every electrical equipment, need magnetic switch be installed for the electric heater water inlet, in the semiclosed cavity of inner core, place the magnetic float, be packed with interior jump ring at the interior center hole wall groove that connects in the outside, shell middle and upper part.When water intaking valve has been opened water and entered electric heater, current will promote the magnetic float and rise to the magnetic switch position along the inner core cavity, make the magnetic switch action send power on signal to the electric autocontrol device, instruction electric heater energising heating.When water intaking valve was shut, the magnetic float moved down because of gravity, broke away from the magnetic switch position, made the magnetic switch action send power-off signal, made the electric heater outage, stopped heating.
Every electrical equipment, only need temperature-sensing probe be installed for the electric heater delivery port at shell upper water flowing interface.Temperature-sensing probe passes to the electric autocontrol device with electric heater leaving water temperature signal, so that the timely adjustment leaving water temperature.
Compared with the prior art, characteristics of the present utility model are water route resistance height, and resistance electric energy power is strong, and is reliable every electricity, guarantee personal safety, and energy one thing dual-purpose, be anticreep safety device, be again into water recoil simulator or leaving water temperature sensing device, effectively reduce the electric heater volume, reduce production costs.

The specific embodiment
Embodiment one electric heater delivery port safe electricity-isolation device
As shown in the figure, inner core 1 and shell 2 that the useful high insulation heat resisting and pressure resisting plastic material of the utility model is made, inner core 1 barrel periphery is furnished with helical form fin 11, to helical groove 21 should be arranged, inner core 1 screws in shell 2 and forms spiral channel 3 on shell 2 inwalls, and straight water channel 12 is arranged at inner core 1 bottom, the nipple 23 that apopore 22 is arranged during shell 2 tops are promising, connect 7 in shell 2 bottom rotation sets have, connect 7 in shell 2 bottom rotation sets have, shell 2 and in be equipped with rubber seal 6 between connecing 7.Present embodiment is equipped with temperature-sensing probe 4 below shell 2 top apopores 22.At this moment, the safe electricity-isolation device can prevent electric leakage, can survey and send electric heater leaving water temperature signal again.
Embodiment two electric heater water inlet safe electricity-isolation devices
This example and embodiment one are basic identical, and different is that temperature-sensing probe 4 is not installed, but in the outside, shell 2 middle and upper parts magnetic switch 9 are installed, and place magnetic float 5 in inner core 1 semiclosed cavity, interior connect 7 center hole wall grooves embed in jump ring 8.At this moment, the safe electricity-isolation device can prevent electric leakage, can send into water signal again.
Embodiment three electric heater list functional safeties are every electrical equipment
This example is basic identical with embodiment one, and different is that temperature-sensing probe 4 is not installed.At this moment, the effect of safe electricity-isolation device only is to prevent the electric heater electric leakage.
