Abstract
The utility model relates to an electric heating element used in electrical heating articles such as electric water heaters, etc. The middle part of the electric heating element is provided with a resistance wire isolated with a metal casing through an insulated terminal; insulating and heat conducting material such as quartz sand is filled between the resistance wire and the metal casing; the surface of the metal casing is coated with a refractory insulating and scale deposit preventing material layer; the material layer can be a solidifying teflon coating layer and can also be an enamel layer and an enamel (gold-silicon) coating layer. Experiments indicate that after the technical proposal of the utility model is used, scales forming at the surface of the metal casing can be effectively prevented so as to always keep higher thermal efficiency; simultaneously, the coating layer can make the metal casing of the heating element and water isolated so as to improve corrosion resistance, and the spending rate of an anode rod in an inner liner of a water heater can be reduced.
Description
Technical field
The utility model relates to a kind of electrical heating elements, especially a kind of electrical heating elements that is used for electric heating articles for use such as electric heater.
Background technology
Understand according to the applicant, the resistance wire of isolating by insulated terminal and metal shell is equipped with at the middle part of electrical heating elements in the electric heater at present, is filled with the insulating heat-conduction material of quartz sand and so between resistance wire and the metal shell.Because contain impurity such as cl-ion in the water, so the long-time use in the surface of electrical heating elements corrosion easily, and gather incrustation scale.As a result, not only shorten the life-span of electrical heating elements, and after using a period of time, the heat efficiency will reduce obviously.
Summary of the invention
The purpose of this utility model is: at the shortcoming that above prior art exists, propose a kind of good antiseptic property and can be in case the electrical heating elements of incrustation of not only having.
Retrieval finds, the Chinese patent that application number is 93246529.3, the applying date is 1993.12.27 discloses a kind of ceramic electric heating pot of being made up of pottery pot body, base, electric heating element, power supply etc.Electric heating element wherein is the metal conductive film that is coated in ceramic bottom of pot body and following side inner surface, also is coated with the teflon adhesive of one deck through cured at ceramic inner surface of pot body.Its thermal radiation loss is little, the heat efficiency is high, good heat insulating.
In order to reach above goal of the invention of the present utility model, the applicant is through experiment repeatedly, materials such as discovery teflon not only have the high temperature anti-adhesion performance, also has the performance that prevents that sediment from gathering, therefore proposed the technical scheme of following electrical heating elements: the resistance wire of isolating by insulated terminal and metal shell is equipped with at this electrical heating elements middle part, be filled with insulating heat-conduction material between resistance wire and the metal shell, it is characterized in that: described metal shell surface-coated has high-temperature insulation to prevent the incrustation material layer.The teflon coating that this material layer had both solidified also can be that adamantine layer, enamel (claiming golden Gui again) wait other high-temperature insulations to prevent the incrustation material layer.
Experiment shows, after adopting the technical solution of the utility model, can prevent effectively that the metal shell surface from forming incrustation scale, thereby remain the higher heat efficiency, this coating also can make the metal shell of heating element and water isolate simultaneously, therefore increase corrosion resistance, can reduce the depletion rate of anode stub in the water heater liner.
In addition, between metal shell and the anti-incrustation material layer of surface refractory insulation, the coats of metal such as chromium, nickel can also be arranged, thereby further strengthen antiseptic property.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the structural representation of the utility model embodiment two.
Embodiment
Embodiment one
Present embodiment is a kind of electrical heating elements that is used in the electric heater, as shown in Figure 1: insulated terminal 1 is fixedlyed connected with hook-shaped metal shell 3, the resistance wire of isolating with it is housed in the metal shell 3, is filled with the quartz sand insulating heat-conduction material between resistance wire and the metal shell.Metal shell 3 surface-coated have teflon coating 4, and this coating not only has desirable high temperature resistant, insulation property, and can prevent incrustation, have therefore increased corrosion resistance, can reduce the depletion rate of anode stub in the water heater liner.
Insulated terminal 1 also is connected with the nipple 2 that is used to install, and therefore can screw on the water tank that is installed in electric heater, and dismounting is all very convenient.
Embodiment two
Present embodiment also is a kind of electrical heating elements that is used in the electric heater, as shown in Figure 2.Different with embodiment one is that insulated terminal 1 is fixedlyed connected with L shaped metal shell 3, is connected with the bowl-type bump joint 2 that is used to install simultaneously.Metal shell 3 surface-coated have enamel (claiming golden Gui again) layer 4, therefore also can prevent incrustation, improve corrosion resistance.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
Claims (7)
