Description

A kind of duct type electrical heating module

Technical field:

This practicality newly relates to a kind of duct type electrical heating module, is specially adapted to the circulation heating of water body in the foot bath.

Background technology:

Existing foot bath product is in the ascendant, is well received by consumers, and especially has automatic heating and constant temperature function, exempts the worry of changing water for foot-immersing person.The heating module of tradition foot bath is divided into two kinds, the embedded electric hot plate of the first, and it two is electrothermal tube; The former directly is embedded in the basin, and electric hot plate directly contacts with water, reaches the purpose that adds hot water; The latter namely is when utilizing current through electrothermal tube, to be heated.More than two kinds of structures all to adopt aluminium alloy be shell, be pyrotoxin with the ceramic heating element, ceramic heating element is embedded in the chamber of shell after the insulation paper bag is wrapped up in, and with this heat is conducted to aluminum alloy casing, flow heated water again.Owing to only take the insulating paper insulation measures, be prone to induced electricity, moreover insulating paper is easy to or punctures aging, there is potential safety hazard; Moreover ceramic heating element is along with temperature raises, and heating power is downward trend gradually.Especially duct type structure, heater is folded in the both sides of water pipe, and heat conduction efficiency is low.How to improve deficiency of the prior art, namely become the object of the utility model research.

Summary of the invention:

The purpose of this utility model is that a kind of electrothermal tube of design is embedded in the pipeline, directly heats the duct type electrical heating module of flowing water.

Technical solutions of the utility model are achieved in that a kind of duct type electrical heating module, comprise pipeline and electrothermal tube, it is characterized in that electrothermal tube has heating section and electrode section, described heating section is in the pipeline, electrode section passes the tube wall of pipeline, and stretches out the pipeline outside, and power supply source inserts.The heating section of electrothermal tube is immersed in the flowing water of pipeline, directly the water body heating to flowing through.

Described pipeline is that aluminum material is molded directly within on the electrothermal tube, and the heating section outside of described electrothermal tube is enclosed with the aluminium layer with the duct wall disjunctor.The formation secondary is sealed, even the electrothermal tube breakdown fault can not contact water body yet.

Described pipeline is that aluminum material is molded directly within on the electrothermal tube, the tube wall adhesion of the electrode section of described electrothermal tube and pipeline or have water-stop.

Above-mentioned inner-walls of duct and being exposed to outside the electrothermal tube in the pipeline has insulating barrier on all.

The outside of described electrothermal tube is provided with insulating barrier, then pipeline in the post forming.

The described electrothermal tube that is in the pipeline, heating section at least becomes helical structure, and has the flowing water passage at the spiral center.Make heating section spiral center all contact with water body with the outside, increase heat transfer area, and the pipeline of equal length, it is bigger that power can be done.

The described electrothermal tube that is in the pipeline, heating section at least becomes wave structure.

Perhaps be in the electrothermal tube in the pipeline, the heating section parallel organization that becomes to turn back.All can reach the purpose that improves power.

The utility model is skillfully constructed, compact conformation, characteristics that the thermal efficiency is high; Take full advantage of ripe electrothermal tube technology, organicly be combined with pipeline, adopt aluminum material, direct post forming pipeline on electrothermal tube, not only good integrity also can be sealed the raising security to an electrothermal tube heating section secondary; Again electrothermal tube structure in the pipeline is carried out spiral, wave or the design of turning back, can improve the power of unit length pipeline greatly.The utility model is fit to the liquid heating of all pipelines of flowing through, and especially is fit to use on the existing foot bath.

The specific embodiment:

Embodiment one:

With reference to Fig. 1, Fig. 2 and Fig. 3, duct type electrical heating module comprises pipeline 1 and electrothermal tube 2, and this electrothermal tube 2 has heating section 21 and electrode section 22, electrode section 22 do not generate heat in case installs or the equipment fixed on, this is the feature of prior art; Described heating section 21 is in the pipeline 1, and pipeline 1 is molded directly within on the electrothermal tube 2 for aluminum material, is enclosed with the aluminium layer 11 with the duct wall disjunctor in heating section 21 outsides of electrothermal tube 2, forms the secondary encapsulating structure, can improve the security performance of electrothermal tube 2 greatly; Electrode section 22 passes the tube wall of pipeline 1, and stretches out pipeline 1 outside, and power supply source inserts.When described pipeline 1 moulding, but straight forming has the installation site of temperature controller 3, in order to temperature controller 3 is installed during the assembling finished product.As the end view drawing of Fig. 3, electrothermal tube 2 forms a crescent flowing water passage 4 with pipeline 1, to allow water body flow through, forms sufficient heat exchange.
