Abstract

Device incorporated into a mirror 2, 3 to avoid the formation of misting; in which the reflecting surface of the mirror 2, is adhered to the overall device consisting of successive sandwich-type layers in which appear two of electrical insulation material 4, 6, while to the outer layer of electrical insulation material is attached another layer of thermal insulation 7 and another final layer 8 for anti-humidity and mechanical protection. The electrical resistance 5 is connected to the power line to achieve a temperature at the mirror above that of dew point. <IMAGE>

Description

DEVICE INCORPORATED INTO A MIRROR TO AVOID THE FORMATION or MISTING The present invention refers to a device incorporated into a mirror to avoid the formation of misting.
The problem is already known that arises when misting is formed on a mirror so that nothing can be seen in it, for example, in bathrooms, automobiles, etc., that is, while the misting covers the mirror the latter is practically unusable until the misting is cleaned off.
This problem is known from physical principles, that is, that misting occurs when the temperature of the mirror is lower than that of the dew point.
The intention of the invention is to design a simple and novel device that keeps the temperature of the mirror above the dew point.
This device can be used, because of its make-up, to form a part of all types, qualities, shape and size of mirrors, allowing all classes of finishes, frames and incorporation with the furnishings or construction of the wall behind the mirror, and also on cupboard doors and the walls or bases of bathroom cabinets.
According to the present invention there is provided a device incorporated into a mirror to avoid the formation of misting; wherein the reflecting surface of the mirror is attached to the overall device consisting of successive sandwich-type layers, of which two are of electrical insulation material between which is an electrical resistance, and wherein the electrical resistance is connected to the power line to obtain a temperature on the mirror above the dew point.
The heating of the mirror is by the Joule effect, for example using flat, printed or spiral type resistances.
The device has the great advantage of being simple in its constructional aspect and also presents no difficulties in installation or use.
The device consists of placing a metal layer on the back of the glass and the former, together with the glass, form the mirror.
On the sandwich defined by the two layers of electrical insulation material and intervening electrical resistance there may be affixed end electrical insulation and on this a protective layer of the fibre glass type with polyester, plastic or metal.
The device, constituted as described, can be framed with the mirror.
The glass and metal layer form the mirror as already indicated above.
Therefore the device is defined by the electrical resistance and the two covering layers of electrical insulation, one of them fixed to the rear side of the mirror, while the other insulating layer is attached to another layer of thermal insulation and a further backing protection layer.
In order to more easily understand not only the make-up but also the actual use the the object of the invention, reference is made below to various practical examples made up, the said examples being'1 merely enunciative and in no case limiting the invention, all as shown in the attached drawings, in which: Figure 1 shows a side view of, for example, a bathroom cabinet including a mirror with the invention device.
Figure 2 shows a side view of the stratification of the layers of the device attached to a mirror.
Figure 3 shows a sectional view of the whole mirror and device.
Figure 4 shows a side view of a variation in the make-up of the device.
Figure 5 shows a side view of a variation in the make-up of the device.
Figure 6 shows a front view of the invented device.
Figure 7 shows a sectional view of the line VII-VII of Figure 6.
With reference to the drawings, these show: in Figures 1, 2 and 3 the device 1 that is placed on the reflecting surface 2 of the glass 3.
As is known the glass 3 and the reflecting surface 2 form the mirror.
To the reflecting surface is adhered the body of the device 1 formed by a sandwich-like group made up of a layer 4 of electrical insulation to which is attached another formed by an electrical resistance 5, on which goes another layer the same as layer 4.
On the layer 6 is attached another of thermal insulation 7 and on this a last protective layer 8, for example, fibre glass with polyester or plastic or metal.
The device -thus formed by the layers 4, 5, 6, 7 and 8 can go into an-invisible frame 9 and the whole with the mirror into a frame 10.
The electrical resistance may consist of a device appropriate for electrical resistances with an already known connection to the power line.
The device I in Figure 4 is formed by a wall or partition 11, for example of brick 12, on one of whose end faces is attached the mirror 13 while on the other face appears an electrical resistance 14 covered by insulation 15 to form a partition.

Claims (3)

1. A device incorporated into a mirror to avoid the formation of misting; wherein the reflecting surface of the mirror is attached to the overall device consisting of successive sandwich-type layers, of which two are of electrical insulation material between which is an electrical resistance, and wherein the electrical resistance is connected to the power line to obtain a temperature on the mirror above the dew point.
2. A device according to claim 1, wherein the layers forming the device are placed in an invisible frame; and the device and the mirror are set in an external frame.
3. A device according to claim 1 or 2, wherein another layer of thermal insulation and an outer layer of anti-humidity and mechanical protection are attached to the layer of electri- cal insulation material remote from said mirror.
4 A device to avoid misting of a mirror, constructed and arranged substantially as hereinbefore described with reference to, and as illustrated in, Figures 1 to 3 of the accompanying drawings.
