Abstract
The utility model discloses an electric heating plate with single heating side which is composed of a mica plate and an electric heating wire. The utility model is characterized in that the electric heating wire over 90% is arranged on the same heating surface of a mica support plate. Compared with the existing electric heating board, the service life of the electric heating plate is improved 0.6-6 times, the heating area is large, and the temperature is uniform.
Description
The present invention relates to a kind of electric calorifie installation that is specially adapted for cooking plate or similar heating plate.
Existing electric hot plate, mainly constitute as used electric hot plates such as electric cup, electric food warmer, electric iron by heating wire and micarex, concrete structure is heat generating components of clamping between two micarexs, this heat generating components is wrapped on two sides of a mica supporting plate spirally equably by heating wire, therefore it has two electrothermal wire heating's faces, the two ends of heating wire are connected to lead-in wire, and this electric hot plate is placed in heated object need heating place.Electric hot plate is positive towards the one side of heated object, and the heating wire of this face is the front heating wire, and the micarex of this face is the front micarex, and another side then is a reverse side, and its heating wire is the reverse side heating wire, and its micarex is the reverse side micarex.This electrothermal plate structure is simple, and is of many uses, but it exists the major defect that heating wire blows easily, and useful life is short.Its reason is that the reverse side micarex outside often is furnished with heat insulation layer, and heat can only be directed to the heated object transmission, and front heating wire and heated object are near, an alternating floor front micarex, and it is fast to conduct heat, and is difficult for generation high temperature.And the reverse side heating wire is far away from heated object, an alternating floor mica supporting plate and one deck front micarex, and the difficulty of conducting heat easily produces high temperature.Show that according to equation of heat conduction calculating and measured result the reverse side heating wire is higher 0.5～2 times for the temperature difference of heated object than front heating wire, this blows with regard to making reverse side heating wire Yin Gaowen easily, has a strong impact on the life-span of electric hot plate.
Task of the present invention is to design a kind of new electrically heating plate of long service life.
The drawing explanation:
Fig. 1 is that single heating face electric hot plate of the present invention is by the structural profile schematic diagram of putting on heated object, among the figure 1---heated object, 2---the front micarex, 3---heating wire, 3 '---the heating wire lead-in wire, 4---the mica supporting plate, 5---the reverse side micarex, 6---fixture, 7---heat insulation layer.
Fig. 2 is the heat generating components structural representation of single heating face, among the figure 3---and heating wire, 3 '---the heating wire lead-in wire, 4---mica supporting plate, 4 '---eyelet, 4 "---recess.
Below in conjunction with description of drawings particular content of the present invention.
Main points of the present invention are the heat generating components of electric hot plate has been done to improve design, as shown in Figure 1, be clamped between front micarex (2) and the reverse side micarex (5) by the heat generating components of fixture (6), formed single heating face electric hot plate single heating face.As shown in Figure 2, the edge of the mica supporting plate (4) of this heat generating components has some eyelets (4 '), heating wire passes these eyelets (4 ') and is fixed on the mica supporting plate (4), and makes heating wire (3) more than 90% be arranged in the front of mica supporting plate (4).In order to prevent that the heating wire (3) on mica supporting plate (4) edge from sliding, (4 ") are fixed can to open recess at the edge of mica supporting plate (4) in case of necessity.When heating wire (3) span was big, heating wire (3) can adopt the method for passing through last close two eyelets of mica supporting plate (4) (4 ') midway to be fixed.
Single heating face electric hot plate of the present invention with existing electric hot plate relatively, its major advantage is the front that its heating wire more than 90% (3) is arranged in mica supporting plate (4), and the heating wire of the reverse side of mica supporting plate (4) is very few, so the heat that reverse side produces is also very few, the reverse side heating wire is difficult for producing high temperature, thereby overcome existing electric hot plate because the shortcoming that reverse side heating wire temperature Gao Eryi is blown makes to have prolonged 0.6～6 times useful life.Because the heating wire (3) more than 90% is arranged in the front of mica supporting plate (4), and therefore, positive electrothermal wire heating's area has increased nearly one times, heated object (1) obtains easily than even temperature simultaneously.
Circular single heating face electric hot plate as a kind of electric cup heating usefulness, its structure as shown in Figure 1, front micarex (2) and reverse side micarex (5) are diameter 84mm, the micarex of thickness 0.15mm, the thickness of mica supporting plate (4) is 0.3mm, the heat generating components of single heating face as shown in Figure 2, eyelet (4 ') is arranged in from 2mm place, mica supporting plate (4) edge, it is 0.4 * 0.1mm that heating wire (3) adopts the cross section
2Shape nickel filament coiling partially, its total length is 4.7 meters.This electric hot plate operating voltage 220V, rated power is 300W, effective unit area heating power 6W/cm
2, be contained in the stainless steel cup to being heated on the parts (1), and load onto heat insulation layer (7) at its reverse side, the test of heating up water, its result shows and surpasses 2000 hours useful life, prolongs more than one times than the existing like product life-span.
Embodiment 2
A kind of single heating face electric hot plate as electric iron heating usefulness is that mica supporting plate (4) and the cross section of 0.3mm is 0.6 * 0.1mm with thickness
2, length is that to turn to the efficient heat generation area be 70cm to 4.2 meters nichrome wire (3)
2The heat generating components of single heating face, be clamped in thickness and be between the front micarex (2) and reverse side micarex (5) of 0.15mm, and fixed and make with fixture (6), effective unit area heating power is 7.1W/cm
2, operating voltage 220V, rated power are 500W, test result, and this electric hot plate can reach 2000 hours in the electric iron following life-span of normal operating position, surpasses existing like product more than one times.
Claims (3)
1, a kind of electric hot plate that mainly by front micarex [2] and reverse side micarex [5] heat generating components is clamped in the centre and constitutes is characterized in that this heat generating components is the front that the heating wire more than 90% [3] is arranged in mica supporting plate [4] by the eyelet [4 '] of mica supporting plate [4] edge.
2,, it is characterized in that heating wire (3) span on being arranged in mica supporting plate (4) can adopt the method for passing through close two eyelets of mica supporting plate (4) (4 ') midway to be fixed when big according to the described electric hot plate of claim 1.
It is characterized in that according to the described electric hot plate of claim 1 that 3, (4 ") are in case the heating wire slip can to open recess in case of necessity at the edge of mica supporting plate (4).
