The present invention relates to a device for preventing fogging of a mirror, and more specifically, as a device for preventing fogging of a mirror to prevent fogging caused by fogging in a mirror installed in a place where hot water is used, such as a bathroom or a bath. It is energy-saving, safe, and relatively simple to construct, and to a mirror fogging prevention device that can more effectively prevent and suppress the fogging phenomenon of the mirror.

In general, a mirror is the shape of an object by coating a silver-colored film with high reflectivity on the back side of a transparent plate such as glass or depositing a multi-layered film of an entire medium. It is an object made to illuminate, and is mainly attached to the wall of a building such as a bathroom or bathhouse, and is used to illuminate the user's appearance when washing, making up, or taking a shower.

On the other hand, it is a common phenomenon when using a mirror in a space where the circulation of air is closed due to high temperature and high humidity such as a bathroom or bath, and everyone must have experienced the experience of fogging hazy on the surface of the mirror. The'steam-up' of such a mirror is a type of dew condensation that occurs when the internal air of a bathroom or bath is above the dew point temperature and the amount of water vapor is above the saturated humidity. It is a phenomenon formed by water droplets upon hitting a relatively cold mirror surface. Therefore, the fogging phenomenon of the mirror mainly occurs when hot water is used, and when such fogging occurs, the desired shape can be seen only after cleaning the surface of the mirror, which incurs considerable hassle.

Accordingly, several technologies to prevent fogging of the mirror were introduced. Korean Patent Application Nos. 10-2004-0005951, 10-1999-0015357, Utility Model Application Nos. 20-1997-0004315, and No. 20-1999-0003332, etc. discloses a technology to prevent fogging by increasing the temperature of the mirror by arranging a separate heating wire that generates electric heating on the back of the mirror, and Korean Utility Model Application No. 20-1999-0024289, Patent application numbers 10-2002-0063651, 10-1999-0053167, 10-1995-0035754, utility model application numbers 20-2003-0014457, 20-2002-0009630, etc. A technology for preventing fogging by increasing the temperature of the mirror by installing a separate hot water circulation pipe for circulation and spraying of hot water on the back of the mirror is disclosed.

In addition, the heat diffusion unit is characterized in that it has a zigzag or horizontally cross-arranged grid along the rear surface of the mirror, or a sheet shape closely adhered along the rear surface of the mirror, wherein the mirror is a transparent plate and a reflective film coated on the rear surface of the transparent plate. Including, wherein when the heat diffusion portion is in the shape of the plate, the reflective layer is characterized in that the heat diffusion portion, the heat bonding portion, the heat conduction portion, and the heat diffusion portion, respectively, tungsten (W), iron (Fe), copper It is characterized in that it is made of a high-conductivity metal including (Cu), gold (Au), silver (Ag), and aluminum (Al), or a nonferrous metal including an alloy or ceramic of at least one of the high-conductivity metals.

According to, it can be divided into several embodiments. Accordingly, the following description will be described separately for each embodiment, and for convenience, common contents will be mainly described in other embodiments instead of describing in detail through the first embodiment.

Embodiment 1

1 is a schematic view showing a mirror fogging prevention device 20 (hereinafter, simply referred to as a fogging prevention device 20) according to a first embodiment of the present invention.

At this time, the anti-fog device 20 according to the first embodiment of the present invention uses a hot water pipe 12 previously installed in the building as a heat source, where the hot water pipe 12 is all pipes through which hot water flows ( path), for example, a water supply pipe or a faucet, a shower head, a pipe related to a shower facility, etc., and is a part already installed in a building for hot water supply rather than a separately added component for the present invention. . This can be easily understood by referring to the cold water pipe 14 and the faucet 16 shown in the drawings. Therefore, the anti-fog device according to the first embodiment of the present invention is applied to the mirror (M) in the building where the hot water pipe (12) is already installed, but the fogging phenomenon of the actual mirror (M) is Considering that it occurs mainly when hot water is used in a bathroom or a bathroom, this should be viewed as highlighting the technical utility rather than limiting the present invention.

As can be seen, the anti-fog device 20 according to the first embodiment of the present invention can be divided into four parts. That is, a hot water pipe 12 that is already installed in a building and heated by the latent heat of hot water flowing through the building, and the hot water pipe 12 is connected to the hot water pipe 12 so that the heat of the hot water pipe 12 is thermally coupled. The heat-conducting part (62) is connected to the heat-conducting part (22) and the heat-conducting part (62) to conduct heat from the heat-conducting part (22), and the rear surface of the mirror (M) while being connected to the heat-conducting part (62). It is arranged along the heat diffusion portion 82 for heating the mirror (M) with heat conducted through the heat conduction portion 62.

Each part of the anti-fog device 20 according to the first embodiment of the present invention will be described in detail with reference to the drawings separately mentioned in addition to FIG. 1. At this time, for convenience, duplicate descriptions are avoided by assigning the same drawing numbers to the same parts that play the same role.

First, the hot water pipe 12 is a heat source of the anti-fog device 20 according to the first embodiment of the present invention, and when the user manipulates the faucet 16 to use hot water, hot water flows. It is naturally heated by the latent heat of hot water.

At this time, the hot water pipe 12 is a generic term for all pipes through which hot water flows, as mentioned above, and may be a water pipe or a faucet 16, a shower head, a pipe related to a shower facility, etc., and a mirror (M) location In addition, one or more may be appropriately selected in consideration of the installation location of the anti-fog device 20 according to the present invention.

Next, the heat coupling part 22 is a part that matches the heat of the hot water pipe 12 to the heat conduction part 62 by connecting the hot water pipe 12 and the heat conduction part 62, and the hot water pipe 12 and the heat conduction part It is preferable that the large area as close as possible to each of (62) can be prevented from heat loss. For this purpose, a mechanical element called a so-called pipe clamp may be used as the heat fitting part 22, and several examples are shown in FIGS. 2 to 4 including FIG. 1.

First, the heat bonding part 22 shown in FIG. 1 and the enlarged portion A in the circle thereof is formed by bending a plate of a certain length into a pipe shape to make close contact along the outer surface of the hot water pipe 12 while both ends thereof. There is shown a form in which the ends of the heat conduction portions 62 are inserted between the ends of the heat conduction portions 62 by facing each other, and the nut 28 is fastened to at least one through bolt 26 penetrating the both ends 24. . In other words, the heat fitting part 22 of FIGS. 1 and 2 shows a pipe shape surrounding the hot water pipe 12, but a part of the outer surface is opened along the longitudinal direction so that each of both ends 24 is bent to face each other. Shows the form.

Therefore, when the heat conduction part 62 is inserted between the ends 24 and the through bolt 26 and the nut 28 are fastened, the hot water pipe 12 and the heat conduction part 62 are closely connected and fixed. The heat of the pipe 12 is matched to the heat fitting portion 22 and is conducted to the heat conduction portion 62 without loss.

In addition, the heat fitting portion 22 shown in FIG. 3 has a semicircular cross-section perpendicular to the longitudinal direction, and at least one of the first and second fasteners 40 for inserting the heat conductive portion 62 is provided. One end of the half pipe (30,32) is connected by a hinge (34) or a similar mechanical element, and the first and second half pipes (30,32) corresponding to opposite sides of the hinge (34) ) Is formed at the other end of each of the locking end 36 and the locking groove 38 to be fastened or detached in a hook method. In this case, if necessary, the first and second half pipes 30 and 32 may be fastened or separated by separate through bolts and nuts.

Therefore, in a state in which the first and second half pipes 30 and 32 are in close contact with the outer surface of the hot water pipe 12, respectively, the locking end 36 and the locking groove 38 are fastened, and the heat conduction part 62 is attached to the fixture 40. ), the hot water pipe 12 and the heat conduction part 62 are closely connected and fixed to each other, whereby the heat of the hot water pipe 12 is matched by the heat-conducting part 22 and is conducted without loss to the heat-conducting part 62. .

In addition, the heat bonding portion 22 shown in FIG. 4 is the first and second clamp blocks 42 having semicircular first and second grooves 44 and 48, respectively, so as to be in close contact along the outer surface of the hot water pipe 12. ,46), at least one of the first and second clamp blocks 4246 has a hole 50 into which the heat conduction unit 62 is inserted, and the first and second clamp blocks 42 and 46 Is tightly fixed with at least one tab bolt 52 inserted into the second clamp block 46 through the arbitrary first clamp block 42.

Therefore, the first and second clamp blocks 42 and 46 so that the first and second grooves 44 and 48 of the first and second clamp blocks 42 and 46 are in close contact with the outer surface of the hot water pipe 12, respectively. After butt, fasten at least one tab bolt 52 inserted into the second clamp block 46 through an arbitrary first clamp block 42, and insert the heat conduction part 62 into the hole 50. When the hot water pipe 12 and the heat conduction part 62 are closely connected and fixed to each other, the heat of the hot water pipe 12 is matched to the heat mixing part 22 and is conducted without loss to the heat conduction part 62.

In this case, the heat-fusing portion 22, which was examined in FIGS. 2 to 4 including FIG. 1, has a high thermal conductivity, such as tungsten (W), iron (Fe), copper (Cu), gold (Au), and silver (Ag). , Highly conductive metal including aluminum (Al), or at least one of these metals, may be made of non-ferrous metals such as an alloy or ceramic, and conduct heat with the hot water pipe 12 and the heat transfer part 22 and/or the heat transfer part 22 Each contact portion of the portion 62 may be in close contact with each other using a thermal adhesive or the like. Here, the thermal adhesive is a generic term for an adhesive material that adheres to each other between two or more objects and at the same time transfers heat generated from one to the other. For example, a highly conductive metal particle or a resin adhesive material with high thermal conductivity It may be in a form containing metal fiber, and a product commonly referred to as a conductive adhesive may be used.

As a result, the heat coupling part 22 is detachably fixed or detachable to the hot water pipe 12, and when fixed, the hot water pipe 12 and the heat conduction unit 62 are firmly connected to the hot water pipe 12. Heat is transferred to the heat conduction unit 62 without loss. For reference, the contents examined in FIGS. 2 to 4 are only a few examples of the heat fitting part 22 according to the present invention, and the specific shape thereof may be modified as much as possible.

Returning to FIG. 1 again, the heat conduction unit 62 conducts heat of the hot water pipe 12 matched through the heat combination unit 22 and the heat diffusion unit 82 to the heat diffusion unit 82 by connecting the heat connection unit 22 and the heat diffusion unit 82 As a part to be made, a highly conductive metal including tungsten (W), iron (Fe), copper (Cu), gold (Au), silver (Ag), aluminum (Al), or an alloy or ceramic of at least one of these metals It may represent a line or tube shape made of a non-ferrous metal.

At this time, the heat conduction unit 62 is the most characteristic part of the present invention, and is used to transfer the heat of the heat bonding unit 22 to the heat diffusion unit 82 using the'conduction phenomenon' of heat. Unlike the heat conduction unit 62 according to the present invention, the'conduction heat' is moved using the'conduction phenomenon'. Therefore, the heat conduction unit 62 may be free in a specific shape or type as long as it satisfies the corresponding function. For example, a known heat pipe may be used, and the outer surface thereof may be coated with Teflon or other high insulating material. I can. In addition, in order to prevent unnecessary heat loss, the length of the heat conduction unit 62 may be limited to several meters or less.

On the other hand, the heat conduction unit 62 may represent a single line or tube shape connecting the heat bonding unit 22 and the heat diffusion unit 82 as shown in the drawing, but in some cases, a plurality of standardized lengths are connected. It is also possible to use it, and for this purpose, a separate connecting member may be used.

5 and 6 are diagrams showing several examples of the connecting members, respectively, divided into first and second connecting members 72 and 74 for convenience, and connected by respective connecting members 72 and 74. The two heat conductive parts 62 are referred to as first and second heat conductive parts 64 and 66.

First, the first connecting member 72 shown in FIG. 5 has a shape of a straight pipe through which a hollow (中空) is passed. Therefore, by inserting the ends of the first and second heat conducting parts 64 and 66 to be connected to both ends of the first connecting member 72, respectively, it can be connected in a straight line.

In addition, the second connecting member 74 shown in FIG. 6 has a curved pipe shape through which a hollow is passed, that is, an elbow shape. Therefore, by inserting the ends of the first and second heat conducting portions 64 and 66 to be connected to both ends of the second connecting member 74, respectively, it may be connected in a curved shape of a desired angle.

In addition, as shown in FIG. 7, the opposite ends 65 and 69 of the first and second heat conduction units 64 and 66 to be connected are pressed flat to each other to a predetermined thickness, and then overlapped. It is also possible to overlap and fix the ends (65,69) of the first and second heat conduction parts (64,66) by using the connection member (76), and the first to third connection members (72,74,76) ) Are all highly conductive metals including tungsten (W), iron (Fe), copper (Cu), gold (Au), silver (Ag), and aluminum (Al), but it is unnecessary to consist of at least one alloy of these metals. It is preferable because it can prevent heat loss.

Returning to FIG. 1 again, the heat diffusion part 82 is a part that distributes the conduction heat transferred through the heat conduction part 62 to the entire rear surface of the mirror M, and includes tungsten (W), iron (Fe), and copper (Cu). , Gold (Au), silver (Ag), aluminum (Al), a high-conductivity metal, or one or more selected among them, a grid or sheet made of a non-ferrous metal material such as ceramic or the like. . In addition, it is preferable that a separate heat insulating layer 84 covering the heat spreading part 82 is formed on the back of the mirror M, whereby unnecessary heat loss that may be caused by direct contact between the heat spreading part 82 and the wall surface of the building Can be reduced.

On the other hand, the heat diffusion unit 82 of the anti-fog device 20 according to the first embodiment of the present invention can be divided into several types according to the specific shape, so each will be described.

First, the attached FIG. 8 is a cross-sectional view taken along line A-A of FIG. 1, and shows a mirror M and a grid-shaped thermal diffusion unit 82 arranged in a zigzag pattern along the rear surface thereof. In this case, the mirror M may be in a form in which a reflective film 4 having high reflectivity is coated on the back of a transparent plate 2 such as glass or plastic, as in a general case, and a heat diffusion unit ( A heat insulating layer 84 covering 82 is formed.

In this case, in order to physically connect the heat conduction unit 62 and the heat diffusion unit 82, a part of the heat diffusion unit 82 is wound around the end of the heat conduction unit 62 as shown in Fig. 9, which is an enlarged view of the inner circle B of Fig. 1 In this way, the conduction heat of the heat conduction unit 62 is conducted to the heat diffusion unit 82 without loss.

In addition, the attached FIG. 10 is a perspective view showing another example of the heat diffusion unit 82, showing a matrix form cross-arranged horizontally and vertically along the rear surface of the mirror M. At this time, the cross section cut along the line A'-A' is substantially the same as that of FIG. 8, so it will be omitted, and this can also be connected by winding a certain portion around the outer surface of the end of the heat conductive part 62, whereby the heat conductive part 62 Conducted heat is conducted to the heat diffusion unit 82 without loss.

In addition, the attached FIG. 11 is a perspective view showing another example of the heat diffusion unit, and shows the shape of a plate or sheet attached along the back side of the mirror M. At this time, the role of the heat diffusion unit 82 is to distribute the conductive heat transmitted from the heat conduction unit 62 to the entire area of the rear surface of the mirror M, as shown in FIG. 12, and a part of the heat diffusion unit 82 It can be connected to the outer surface of the heat conduction unit 62 by rolling, whereby the conduction heat of the heat conduction unit 62 is conducted to the heat diffusion unit 82 without loss.

In this case, in particular, the cross section cut along the line BB of FIG. 11 is the same as that of FIG. 13 or 14. Through FIG. 13, a plate shape along the reflective film 4 coated on the back side of the transparent plate 2 of the mirror M The heat diffusion part 82 is in close contact, and the heat insulation layer 4 covers it.

At this time, the mirror M represents a form in which a reflective film 4 having a high reflectivity is coated on the rear surface of the transparent plate 2, and when the heat diffusion part 82 is a plate or sheet of a metal material having a high reflectance, Likewise, instead of omitting the reflective film of the mirror M (see 4 in FIG. 13), it is possible to replace the reflective film (see 4 in FIG. 13) by intimately contacting the heat diffusion unit 82 to the rear surface of the transparent plate 2.

On the other hand, the anti-fog device 20 according to the first embodiment of the present invention described above performs an operation of preventing and suppressing fogging of the mirror M at the same time as the user uses hot water, and thus, the user has a separate additional operation. Without it, it is possible to prevent and suppress fogging of the mirror (M).

That is, when the user manipulates the faucet 16 to use hot water, hot water flows through the hot water pipe 12 and is discharged to the faucet 16. During this process, the hot water pipe 12 heated by the latent heat of the hot water The heat of) is conducted to the entire rear surface of the mirror M through the heat coupling part 22, the heat conduction part 62, and the heat diffusion part 82 in order. Therefore, it is possible to effectively prevent and suppress the fogging phenomenon of the mirror (M) without a separate manipulation of the user.

Example 2

15 is a schematic diagram of a fogging prevention device 20 according to a second embodiment of the present invention. In this case, since the same reference numerals are assigned to the same parts that have the same role as those in the first embodiment, duplicate descriptions are omitted, and only differences are described.

As can be seen, as a heat source of the anti-fog device 20 according to the second embodiment of the present invention, a separate heating device 92 is used instead of the hot water pipe 12.

At this time, the heating device 92 may be an electric heating method that is connected to an outlet 90 installed in a bathroom or a bathroom, and a preferred aspect for this is a rod connected to the heat bonding part 22 as shown in FIG. It can be completed by arranging the heating wire 96 for electric heating along the inside of the body 94 of the shape.

Therefore, the heat generated by the electric heating of the heating wire 96 is the same as below), the heat conduction part 62, and the heat diffusion part 82 to the entire rear surface of the mirror M. Conduction, thereby heating the mirror M to prevent and suppress fogging. In this case, if necessary, the heating device 92 can detect the temperature of the water discharged from the humidity sensor 86 or the faucet 16 attached to the surface of the mirror M so as to detect whether the mirror M is fogged. It can be interlocked with at least one of the temperature sensors 88 attached to the faucet 16 so that it can be automatically driven when a fogging phenomenon appears on the mirror M or the user uses hot water above a certain temperature. have.

Meanwhile, some examples discussed above are for explaining the technical idea of the present invention, and the present invention is not limited thereto. Therefore, various modifications within the technical spirit of the present invention should all belong to the present invention, and the scope of the present invention will become more apparent to those skilled in the art through the following claims.
