Description
[technical field]
The present invention relates to a kind of electrothermal tube, particularly for the electrothermal tube of heating liquid.
[background technology]
Electrothermal tube is mainly used on kettle, water heater, the water dispenser etc.The electrothermal tube of existing film heating generally comprises earthenware or quartz ampoule, outside earthenware or quartz ampoule, be coated with heating film, heating film is powered to it by electrode, when the access electric current, the heating film heating, on the liquid of heat in earthenware or quartz ampoule are delivered to pipe, thereby the liquid in earthenware or the quartz ampoule (such as water etc.) is heated, thus can be faster with heating liquid.Because the material characteristic of earthenware and quartz ampoule determines, the temperature difference is larger when contacting hot tube wall in the liquid stream flowing pipe of cold conditions, suddenly cold and hot can make earthenware or quartz ampoule explosion, in case earthenware or quartz ampoule explosion, liquid will directly contact with heating film, and heating film is switched on, thereby causes electric leakage, uses the people of liquid that Danger Electric shock risk is arranged.
[summary of the invention]
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of security performance the high electrothermal tube that is used for heating liquid.
In order to address the above problem, the present invention by the following technical solutions:
A kind of electrothermal tube for heating liquid, it is characterized in that: comprise metal tube, described metal tube is provided with insulating barrier outward, be provided with heat-conducting layer between described metal tube and the described insulating barrier, described insulating barrier is provided with heating film outward, and described heating film is provided with the electrode that electric current is linked into described heating film.
Aforesaid a kind of electrothermal tube for heating liquid is characterized in that: described insulating barrier is to be sleeved on the outer hollow body of described metal tube.
Aforesaid a kind of electrothermal tube for heating liquid is characterized in that: described insulating barrier is the plates that are trapped among described metal tube outer wall.
Aforesaid a kind of electrothermal tube for heating liquid is characterized in that: described insulating barrier is two.
Aforesaid a kind of electrothermal tube for heating liquid, it is characterized in that: described metal tube is the hollow circular pipe, two described insulating barriers are be sticked left arc-like sheet and right arc-like sheet at described metal tube outer wall, and described left arc-like sheet and right arc-like sheet are substantially with described metal tube outer wall parcel.
Aforesaid a kind of electrothermal tube for heating liquid is characterized in that: described heat-conducting layer is the heat conduction oil reservoir.
Aforesaid a kind of electrothermal tube for heating liquid is characterized in that: described metal tube is stainless steel tube, aluminum pipe or copper pipe.
Aforesaid a kind of electrothermal tube for heating liquid is characterized in that: described electrode is located at described heating film two ends.
Aforesaid a kind of electrothermal tube for heating liquid is characterized in that: described insulating barrier is earthenware, quartz glass tube or crystallite madreporic canal.
Aforesaid a kind of electrothermal tube for heating liquid, it is characterized in that: described wall thickness of metal tube is less than or equal to 2mm.
Beneficial effect of the present invention has: a strip metal pipe is set in the insulating barrier inwall, liquid and metal tube are separated, liquid is by in the metal tube, after the heating film energising thereby thermal energy transfer is heated the metal liquid in pipe to metal tube, metal tube is difficult for explosion, can prevent so whole device explosion, and liquid can not occur and flow to heating film and cause leaky, can play safety effect; Insulating barrier can be comprised of one or more pieces plates, can adopt two, can be left arc-like sheet and right arc-like sheet composition, coated with thermally conductive oil between convenient like this wall within it and the metal tube outer wall, easy for installation, prevent that the efficient that gap affects heat is transmitted from appearring in ceramic layer and metal tube, is difficult for explosion with respect to ceramic layer cylindraceous.
