CN2216658Y - Water tap bayonet water heater - Google Patents

Abstract

The utility model relates to a water tap bayonet water heater, which is composed of a clamping seat, a base, a U-shaped heating electrode, a safety box, etc. The utility model can be directly clamped on the water tap for installation, and tap water which is heated in an annular heating cavity passes through a cylindrical zero potential connected with an earth line when the tap water flows out, so that the effluent water is ensured to have no charge. The inner part of the safety box is provided with a protector tube and a power switch, and is provided with a circuit capable of testing whether the positive and the negative poles of a power supply and the earth line are connected with the earth well. The utility model has the advantages of safe and convenient use, simple structure, high efficiency, low cost and long service life, being an ideal article for people to heat cold water in daily life.

Description

Water heater fastened on tap

The present invention relates to a kind ofly, belong to the household electrical appliance series products for people provide the electric heating appliance of hot water.

The electric heater kind of Xiao Shouing is a lot of in the market, 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 are very high, and install and use inconvenience.

The purpose of this invention is to provide a kind of existing structure for water tap, easy to use, cost is low, the life-span is long water heater fastened on tap of not changing.

Purpose of the present invention can realize by following measure: a deck is set is fixed on the tap, at the deck middle part one rubber ring is set, make between tap and the pedestal and seal, fixing inside and outside two U type heating electrodes in the pedestal bottom, live wire and zero line respectively at power supply link, between two electrodes, form a ring-like heating chamber, U type electrode outside is equipped with the cylinder type zero potential and links to each other with ground wire outside, in its outer setting shell is arranged, protective tube is set in the power line centre position in addition and can measures the whether circuit of ground connection of power positive cathode, ground wire.

Below in conjunction with embodiment and accompanying drawing thereof invention is described further:

Fig. 1 is a structural representation of the present invention

Fig. 2 is 1 circuit diagram 1, bayonet socket 2, deck 3, rubber 1 cushion rubber 4, pedestal 5, outer U type electrode 6, water hole 7, interior U type electrode 8, hole for water spraying 9, heating chamber 10, apopore 11, cylinder type zero potential 12, shell 13, ground wire 14, zero line 15, live wire 16, inlet opening 17, safety box 18, light emitting diode 19, resistance 20, protective tube 21, power switch 22, resistance 23, light emitting diode in the safety box of the present invention

Screwed bayonet 1 is fixed on the tap deck 2, rubber ring 3 is installed in deck 2 middle parts, screwing pedestal 4 makes it to connect by rubber ring 3 and tap, running water does not leak outside by inlet opening 16, U type heating electrode 7 links with the live wire 15 of power supply in middle part, pedestal 4 bottom is provided with, be provided with water hole 6 in its underpart, U type electrode 5 links with the zero line 14 of power supply outside interior U type electrode 7 outer setting, be provided with apopore 10 in its side, in the middle of two U type electrodes, form heating chamber 9, the cylinder type zero potential 11 of U type electrode outer setting links with ground wire 13 outside, in its outer setting shell 12 is arranged, its underpart is provided with hole for water spraying 8, go into end at safety box 17 inner protective tubes 20 and power switch 21 control live wires on/off is set, at live wire 15 and 13 of ground wires a light emitting diode 23 and resistance 22 are set, connect and move back electric power starting power switch 21, not working as light emitting diode, then ground wire is obstructed, adjusting the ground wire good earth gets final product, in the middle of live wire 15 zero lines 14, light emitting diode 18 and resistance 19 are set, connect power supply, powered-down switch 21,5 do not work as light emitting diode 18, live wire and zero line are correct the installation, luminous as light emitting diode 18, then live wire and zero line are counter adorns.

The utlity model has the characteristics such as easy for installation, simple in structure.

Claims (2)

1, a kind of water heater fastened on tap, form by bayonet socket, pedestal, U type heating electrode, safety box etc., it is characterized in that the bayonet socket that is connected pedestal top can be fixed on the tap, be fixed with inside and outside two U type heating electrodes in the pedestal bottom, in the electrode outer setting cylinder type zero potential and shell are arranged, a safety box is installed on power line.
