Abstract

The utility model relates to an electric heating antifogging mirror, which belongs to daily use electric heating beauty making appliances. The back of the mirror surface glass of an ordinary mirror is provided with a semiconductive electric heating element which is used to heat the mirror surface glass. Thus, the temperature of the mirror surface is made higher than the temperature of the water vapor in the air. As a result, the water vapor is prevented from being coagulated into fog drops on the mirror surface. The utility model has the advantage of little dissipation of energy, being suitable for bathrooms, families, hotels, and other places which need antifogging mirrors.

Description

Electric heating antifogging mirror

The utility model belongs to daily electric heating lift face apparatus.

Existing glass mirror in the daily life, when using in cold environment, the hot vapour that the people the breathes out mist formation that condenses on cold minute surface thickens minute surface, and using to people makes troubles.In the bathroom that steam fills the air, because vapour concentration is big, the temperature height, mirror mist phenomenon is serious especially.

The purpose of this utility model is to provide a kind of electric heating to prevent fog filter.

Solution of the present utility model is in common two-way mirror back, the heating of device heat mirror surface glass, and minute surface is heated to uniform temperature.

Because minute surface is heated to uniform temperature, for example general room was heated to about 40 ℃ in winter, and mirror temperature is higher than the hot stripping temperature that the people breathes out, and hot vapour can not condense at minute surface; If in the bathroom, mirror temperature can be heated to higherly, for example about 40 ℃-50 ℃, make it higher, thereby these steam are not condensed at minute surface than the vapor (steam) temperature of scattering in the bathroom air, prevent that the mirror mist from occurring.

Fig. 1 is the utility model side-looking part sectioned view;

Fig. 2 is the utility model front view;

Fig. 3 is the utility model heating layout;

The utility model is described in further detail below in conjunction with Fig. 1, Fig. 2, Fig. 3.

Among Fig. 1,1 is minute surface; 2 is metal forming or thin metal skin, plays the uniform heat conduction effect; 3 is electric insulation layer; 4 is heating; 5 is bonnet.

Among Fig. 2,7 is picture frame, and 6 is the time relay, and 8 for connecing the lead of external power.

Among Fig. 2-Fig. 3, be bonded in respectively on two copper mesh bands 9 with the electrode of conducting resinl with several heating 4 two ends, this two copper wires guipure is respectively by being connected with power supply by lead 8 after the lead 10 serial connection time relays 6 again.

In the time will using anti-fog filter, connect power supply (can be designed as safe voltage), heating 4 heatings by metal forming 2 uniform heat conduction, make the two-way mirror intensification of being heated.The power of appropriate design heating 4 when two-way mirror is heated when reaching balance with its heat radiation, can make minute surface remain on 30 °-50 ℃, thereby prevent that steam from condensing at minute surface, reaches antifog purpose.

The time of the being serially connected with device 6 that continues can be cut off the electricity supply automatically between external power supply and heating element heater 4, with the time that the control two-way mirror is heated, saves electric energy.

There is the heating 4 that heats this two-way mirror the back of two-way mirror 1 that is characterised in that of the present utility model.Heating 4 is the products that adopt Wuxi City electronic technology research institute, it is another patent application of the inventor, application number 88100015, it is by the nonmetallic materials substrate, the electrode of composite semiconductor grown layer that plays the electric heating transformation that forms with the plating method at this substrate surface and the connection external power of drawing on this grown layer is formed, and wherein makes the nonmetallic materials of substrate and preferably uses artificial mica sheet.

The utility model is because its heating-up temperature is low, and it is atomic to consume energy, and is best suited for bathroom, hotel and other will use the place of Anti-fog mirror.

Claims

1, the anti-fog filter of a kind of electric heating, mainly comprise minute surface 1, picture frame 7, bonnet 5, semi-conductor electricity thermal element 4, semi-conductor electricity thermal element 4 is by the nonmetallic materials substrate, the composite semiconductor grown layer that plays the electric heating transformation that forms with the plating method at this substrate surface and draw the electrode that connects external power constitute on this grown layer is characterized in that the semi-conductor electricity thermal element 4 that heats this two-way mirror is arranged in the back of two-way mirror 1.
