Abstract

The utility model relates to a defrosting structure of a mirror. The back surface the mirror body is provided with an exothermic pad. The exothermic pad comprises a substrate, an exothermic wire which is arranged on the substrate in helical and winding mode and a seal sheet which is arranged out of the substrate according to the appearance of the substrate, and the heat-resistant insulating material with appropriate size is folded to form the substrate. Wherein, the exothermic wire which is arranged on the substrate is made of a lacquered wire with appropriate density and thickness. After the exothermic wire being energized, the clear mirror surface can be effectively kept. The exothermic temperature is stable, and the use is safe.

Description

The minute surface Defrosting structure

Technical field

The utility model relates to a kind of minute surface Defrosting structure, refers to the minute surface Defrosting structure that a kind of heating temp is stable, insulating properties is good and security performance is guaranteed especially.

Background technology

The mirror that general bathroom is used, regular meeting makes not see Chu when looking in the mirror that causing influences result of use because water vapour is attached to minute surface.In order to improve this problem, known technology has the structure of electrothermal layer in order to demist that be sticked at the mirror back side.As shown in Figure 1, show a kind of known anti-fog filter structure, it mainly is to include compositions such as mirror body 1, heating wire 2, insulating base 31, insulating panel 32 and securing member 4; Wherein heating wire 2 is distributed on the insulating base 31, and 32 clampings of mat insulating panel are to seal heating wire 2, and securing member 4 makes this electrothermal layer be attached at location, mirror body 1 back side, the silk of drawing of heating wire 2 is connected to power supply by transformer again, work as opening power, produce heat energy by heating wire 2 and be attached to the steam of minute surface, make in the more environment of steam (as the bathroom) to have the wiping of not needing and just can keep minute surface anti-fog function clearly with evaporation.

In normal enforcement, though had the heat energy of generation so that minute surface can not produce atomizing because of steam adheres to, it still has the problem of fail safe deficiency in the use about above-mentioned known anti-fog filter structure.The i.e. quick heating of this heating wire 2, the phenomenon that the temperature difference of its moment causes minute surface to break easily, especially, when forgetting the power supply of turning off heating wire, during temperature overheating that heating wire produced, not to cause heating wire to blow, can make that exactly the mirror body breaks, and reduce the useful life of mirror; In addition, this known heating line can't be controlled heating-up temperature effectively to prevent temperature overheating, causes its safety in utilization that problem is arranged, and its magnitude of current height, and when meeting the situation generation of electric leakage, fail safe can not be guaranteed.

Therefore, should there be the minute surface Defrosting structure of another kind of different designs to be improved, with the disappearance of the above-mentioned use of the known anti-fog filter structure of effective solution.

Summary of the invention

The purpose of this utility model is to provide a kind of minute surface Defrosting structure, mainly provides a kind ofly in the environment for use of steam is arranged, and can effectively keep minute surface clear, and the minute surface Defrosting structure that heating temp is stable and security performance is guaranteed.

The utility model is concrete structure and the technological means that reaches above-mentioned purpose, mainly be to be provided with a heating pad to constitute at the mirror body back side, this heating pad includes the substrate that the heat-resistant insulation material doubling by suitable size forms, substantially in the shape of a spiral shape ground twines and to be disposed at on-chip heating line and corresponding substrate profile is incorporated into the outer involution sheet of substrate, wherein being disposed at on-chip heating line is that the enamelled wire of getting suitable density and thickness forms, after the energising of order heating line, can effectively keep minute surface clear, and it is stable to reach heating temp, the problem that no temperature overheating may cause minute surface to break, and security performance such as guarantees at result of use.

Embodiment

Below lift the specific embodiment conjunction with figs. and further specify the utility model structure and effect:

See also Fig. 2, shown in Figure 3, the utility model one specific embodiment, the utility model mainly is made of the heating pad 6 that a mirror body 5 and is arranged at mirror body 5 back sides, and can cover pad 7 by one heating pad 6 is covered with so that this heating pad 6 is attached at mirror body 1 back side locatees.

Please cooperate Fig. 3, shown in Figure 4, heating pad 6 is made up of substrate 61, heating line 62 and involution sheet 63, wherein substrate 61 is formed by the heat-resistant insulation material doubling of suitable size, heating line 62 uniform winding are disposed on the substrate 61, involution sheet 63 is made by heat-resistant insulation material and the profile of corresponding substrate 61 is incorporated on the substrate 61, forms insulating outer layer to cover heating line 62; The line 62 that generates heat again is to be made by enamelled wire, and screwed winding is some encloses on substrate 61 this heating line 62 to be substantially, retracts to the opposite side of substrate 61 in winding the line again and is connected to conductor wire 64, and heating line 62 two ends are external on the conductor wire 64.

According to the formed minute surface Defrosting structure of the utility model, in the environment for use of steam was arranged, after opening switch 65 and making conductor wire 64 energising, electric current can be by 62 heating of heating line, made the minute surface of the mirror body steam that can not condense, to keep minute surface clear.To be disposed at the heating line 62 on the substrate 61 be that the enamelled wire of getting suitable density and thickness forms to the utility model again, make 6 maximum temperatures that can produce of heating pad to preestablish by the configuration density or the thickness of heating line 62, make embodiment as its highest heating temp that can set 35 degree, keep the clear usefulness (also can set the different heat temperature) of minute surface to provide with different regions, guarantee and reach the output that does not have the temperature that exceeds the quata, in order to avoid fully because of heating temp overheated may cause minute surface to break problem.

The heating line 62 of the utility model heating pad 6 is that the enamelled wire of getting suitable density and thickness forms, and its intensification is slower, the temperature difference of no moment, the unlikely phenomenon that causes minute surface to have to break; Especially, heating pad 6 outer surfaces have involution sheet 63 protection to form insulating outer layer, and enamelled wire itself has insulation effect, can effectively prevent to get an electric shock, and security performance is very reliable; Moreover the magnitude of current of enamelled wire is low, and the high temperature of extremely about 110 degree of enamelled wire ability, and heating line 62 no overheated disappearances of blowing can promote useful life; In addition; the utility model is with can be marine glue or the watertight composition that the waterproof plastic material is made so that heating pad 6 is attached at the covering pad 7 of location, mirror body 1 back side; make the safeguard measure that the utility model minute surface Defrosting structure has waterproof and prevents to get an electric shock, to improve function of use.

Sample has been manufactured experimently in structure setting of the present utility model, it confirms to reach the effect of expection via the reality test, the utility model is except simple in structure, manufacturing facility, and possess and in the environment for use of steam is arranged, can effectively keep minute surface clearly outside the function of use, the utility model also has the stable and security performance of the heating temp of heating pad and result of use person such as guarantees, so the utility model is promoted effect than traditional form, has progressive.
