Abstract
The utility model relates to a heating pipe for an electric water heater, comprising the heating resistive conductors of the heating pipe, insulating fillers, a metallic guide pipe, the guide pipe of a temperature controller, a sealed flange disk, a seal ring and the binding post of the heating pipe. A metal cylinder is arranged out of the heating pipe and matched with the flange disk to form a sealed space filled with insulating liquids. Due to the adoption of double metal casings and double insulating materials, the safety performance of the utility model is enhanced obviously. In addition, a detection hole for the insulating liquids is arranged, insulating materials and the heating pipe can be detected and replaced at any time, and the service life of the water heater is prolonged.
Description
The utility model relates to a kind of heat-generating pipe, particularly a kind of heat-generating pipe that mainly is applicable to electric heater.
In the prior art, the metal catheter of heat-generating pipe is immersed in for a long time in the water tank of electric heater and heats, and is mostly undressed hard water, is easy to make the metal catheter shell of heat-generating pipe to produce incrustation scale and corrosion.These incrustation scales reduce the heating efficiency of heat-generating pipe, more seriously can the corroding metal conduits, will make it in the course of time to break, and cause water to infiltrate and cause electric leakage.If use this electric heater this moment, just be very easy to cause the electric shock casualty accident.
The purpose of this utility model aims to provide a kind of simple in structure, easy to detect, safe and reliable heat-generating pipe, to overcome the deficiencies in the prior art part.
Electric heater heat-generating pipe by this purpose design, the heating resistance wire, insulation filler, the metal catheter that comprise heat-generating pipe, the thermostat conduit, sealing flange and sealing ring and heat-generating pipe binding post, its architectural feature is that to be provided with a metal outside described heat-generating pipe simplified, and cooperate the formation seal cavity with ring flange, iknsulating liquid is housed therebetween.
This product can obviously improve security of products owing to adopt double-level-metal shell and double hyer insulation material; Be provided with iknsulating liquid in addition and detect the hole, can detect, change insulating material and heat-generating pipe at any time, prolong the useful life of water heater.
Accompanying drawing is the utility model one example structure schematic diagram.
Fig. 1 is the assembly structure front view.
Fig. 2 is that the A of Fig. 1 is to view.
Referring to accompanying drawing, at heating resistance wire 3, insulation filler 4, the metal catheter 1 of existing heat-generating pipe, thermostat conduit 2 is on the basis of sealing flange 5 and sealing ring 6 and heat-generating pipe binding post 7, increase a metal cylinder 10, and cooperate the formation seal cavity with ring flange 5.On ring flange 5, be provided with liquid injection hole 8, from the hole, inject iknsulating liquid 9,, and seal with screw as transformer oil.Like this, heat-generating pipe metal catheter 1 is insulated liquid 9 fully and surrounds, and what contact with water in the electric heater water tank is metal cylinder 10, and heat-generating pipe metal catheter 1 is then isolated fully with water.The infiltration even metal cylinder 10 breaks, iknsulating liquid 9 spill can not cause electric leakage and electric shock accidents yet.And, the people that can dirt after iknsulating liquid spills has a bath, prompting user heat-generating pipe need have been changed, and has more increased fail safe.7 places can be provided with the ceramic insulation ring at binding post, to increase the insulating properties of wiring place.But at liquid injection hole 8 place's joint detection instrument or alarms, can detect what of dielectric at any time,, can report to the police when arriving less when a certain amount of.
