Abstract
The utility model relates to an electric heating-membrane heater, comprising a basal layer, an electrothermal film, an insulating water-proof layer and electrodes. The electrothermal film has multiple layers; the multiple layers are separated with each other by the insulating water-proof layers; each layer of the electrothermal film forms a parallel connection. Because the multi-layer structure of the electrothermal film is adopted, large electric heating power can be achieved on a small area, the magnitude of power can be conveniently regulated simultaneously, the power regulation range is large, and the uniform heating is guaranteed.
Description
The utility model relates to a kind of electric heating body, particularly a kind of electrothermal film heater.
The majority of existing electric heating appliance be with the metal electric heating silk as electric heating body, and there is following shortcoming in the metal electric heating silk as electric heating body: (1) heat efficiency is low, generally has only 40～60%; (2) heating is inhomogeneous; (3) working temperature height (more than 800 ℃), oxidation easily, useful life is short; (4) must there be resistant to elevated temperatures insulating material to be used the cost height as pottery, mica sheet, asbestos etc.In recent years the electrothermal film type electric heating body of Chu Xianing has heat efficiency height, and (can reach more than 85%), homogeneous heating, long service life, low cost and other advantages have overcome the above-mentioned shortcoming of metal electric heating silk to a certain extent.But existing electrothermal film heater all is a single layer structure, is difficult to obtain bigger electrical heating power at limited area, is difficult to especially be applicable to that heating surface (area) (HS is little needs more powerful electric heating appliance again.In addition, the electrothermal film heater of this single layer structure is not easy to regulate the size of power; Though Electric radiant Heating Film can be separated into independently several, concern the size of regulating its electric thermal power by the series and parallel that changes between each piece Electric radiant Heating Film, but only cover the part of electric heating appliance heating surface owing to every Electric radiant Heating Film, so have the uneven problem of heating, and its power regulating range is smaller.
The purpose of this utility model is that the structure that has electrothermal film heater is made improvements, and makes it can reach bigger electrical heating power on the area of limited (less), and the size that can regulate power easily, can guarantee homogeneous heating again.
Electrothermal film heater of the present utility model is made of basalis, Electric radiant Heating Film, insulating waterproof layer and electrode, and Electric radiant Heating Film wherein has multilayer, between every layer of Electric radiant Heating Film insulating barrier is arranged, and each layer Electric radiant Heating Film forms by electrode and be connected in parallel.According to above-mentioned electrothermal film heater of the present utility model, the number of plies of its Electric radiant Heating Film is generally 2～4 layers.Electrode on each Electric radiant Heating Film can be separately independently, forming parallel connection by lead or other conductor again is connected in series, or form parallel connection again through change over switch and be connected in series, like this, by the control transformation switch is the number of plies of may command energising Electric radiant Heating Film, thereby realizes the size adjustment to electrical heating power easily; The electrode that also can be same end on each layer Electric radiant Heating Film fuses (in other words, the same end of each layer Electric radiant Heating Film connects same electrode), directly forms to be connected in parallel.
Because electrothermal film heater of the present utility model adopts multilayer Electric radiant Heating Film parallel-connection structure,, generally can reach 2～4 times of existing individual layer electrothermal film heater so can on less area (basalis area), reach bigger electrical heating power.Can accelerate the firing rate of electric heating appliance, be specially adapted to that heating surface (area) (HS is little to need more powerful electric heating appliance again; In addition, by the change over switch number of plies of may command energising Electric radiant Heating Film also, thus the size that can regulate electrical heating power easily, and power regulating range is bigger, the number of plies of Electric radiant Heating Film is many more, and the adjustable power scope is big more; Simultaneously, because every layer of Electric radiant Heating Film all covers whole heating surface, so can guarantee homogeneous heating.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 and Fig. 2 are the structural representations of the utility model electrothermal film heater.
Among Fig. 1 and Fig. 2, Electric radiant Heating Film 2 is a sandwich construction, on basalis 1, has insulating waterproof layer 3 to separate between every layer of Electric radiant Heating Film; Outside in the outermost layer Electric radiant Heating Film also is coated with insulating waterproof layer, both can play the insulative water-proof effect, also Electric radiant Heating Film is shielded; Each layer Electric radiant Heating Film 2 two ends are connected with electrode 4, and the electrode on each layer Electric radiant Heating Film can be independent separately (as shown in Figure 1), also can fuse (as shown in Figure 2).Each layer Electric radiant Heating Film is by electrode or form through lead and change over switch and power supply and be connected in parallel.Basalis 1 can be the arbitrary shape that materials such as glass, pottery, enamel or metal are made.When basalis for conduction or insulation property are relatively poor when material (as metal, electrothermal dark-red pottery etc.) is arranged, between itself and the Electric radiant Heating Film one deck insulating waterproof layer (as shown in Figure 2) should be arranged, to guarantee to have the good insulation performance performance.
The utility model can adopt various types of Electric radiant Heating Film (as semiconductor film membranous type Electric radiant Heating Film, paint-type electric heating film etc.) of existing similar technology, the material (composition) that comprises Electric radiant Heating Film is all identical with prior art with manufacture method, and the insulating waterproof layer that is adopted is also identical with existing similar technology with the material of electrode and manufacture method.
