CN2211039Y - Water-tap clamping-type water-heater - Google Patents

Abstract

The utility model relates to a water-tap clamping-type water-heater which is composed of a clamp port, a base, a U-shaped heating electrode, an electricity leakage protective box, etc. The utility model can be directly clamped on the water-tap for installation. Tap water which is heated in an annular heating cavity flows through a cylindrical zero potential before flowing out, which ensures that the effluent water takes no charge. The electricity leakage protective box is internally provided with an electricity leakage protector having leakage current less than or equal to 10 ma, a protective pipe, a power switch, and a circuit capable of testing that whether the fire wire, the zero wire and the earth wire of a power supply contact the earth well. The utility model has the characteristics of convenient operation, safety, practicality and high thermal efficiency, being an ideal article for people to heat cold water in daily life.

Description

Water-tap clamping-type water-heater

The utility model relates to a kind of for people provide the electric heating appliance of hot water, belongs to the household electrical appliance series products.

The electric heater kind of selling on the market is a lot, but adopts the heating wire heating more, and easily oxidation is blown, and causes service life short, mostly is storage water heater in form, because additional water storage device, its complex structure, cost height are installed and used inconvenience.

The purpose of this utility model provides and does not a kind ofly change that existing structure for water tap can heat, easy to use, water heater fastened on tap that cost is low.

The purpose of this utility model can realize by following measure: a bayonet socket is set is fixed on the tap; one rubber ring is set between bayonet socket and pedestal; make between tap and pedestal and seal; in the pedestal bottom is fixing; outer two U type heating electrodes; respectively with power firestreak; zero line links; between two electrodes, form a ring-like heating chamber; U type electrode outside is equipped with the cylinder type zero potential and ground wire links outside; in its outer setting shell is arranged; the centre position of power line live wire is provided with earth leakage protective device and the protective tube of leakage current smaller or equal to 10mA in addition, and can measure power firestreak; whether zero line and ground wire the circuit of good earth.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described further:

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the circuit diagram in the utility model earth leakage protective box

1; bayonet socket 2; rubber ring 3; pedestal 4; shell 5; cylinder type zero potential 6; apopore 7; outer U type electrode 8; water hole 9; heating chamber 10; hole for water spraying 11; interior U type electrode 12; ground wire 13; zero line 14; live wire 15; earth leakage protective box 16; inlet opening 17; 22; resistance 18; 23; light emitting diode 19; power switch 20; earth leakage protective device 21; protective tube

Screwed bayonet 1 is fixed on the tap pedestal 3; pedestal 3 upper center are provided with rubber ring 2 and guarantee to seal between tap and pedestal; running water does not leak outside by inlet opening 16; U type heating electrode 11 links with the live wire 14 of power supply in middle part, pedestal 3 lower ends is provided with; be provided with water hole 8 in its underpart; U type electrode 7 links with zero-power line 13 outside interior U type electrode 11 outer setting; its side is provided with apopore 6; in the middle of two U type heating electrodes, form heating chamber 9; heating electrode can adopt metal material; U type electrode outer setting has metal rounding cartridge type zero potential 5 and ground wire 12 to link outside; be provided with shell 4 in its outside; shell 4 lower ends are provided with hole for water spraying 10; go into to be provided with protective tube 21 at earth leakage protective box 15 live wires; earth leakage protective device 20 is as double insurance; at power firestreak 14 and 13 of zero lines light emitting diode 18 and resistance 17 are set; power-on switch 19, if light emitting diode 23 does not work, then ground wire is obstructed; adjust ground wire 12; powered-down switch 19, if light emitting diode 18 does not work, then power firestreak 14 is installed correct with zero line 13; if light emitting diode 18 is still bright; then power firestreak 14 and zero line 13 reversal connections are adjusted live wire 14 and zero line 13, can use.

The utlity model has safe ready, the characteristics such as simple in structure, cost is low.

Claims (2)
