Description

Blind for plane heater {Blind for plane heater}

The present invention relates to a blind for a planar heating element, and more particularly, by utilizing the advantages of the planar heating element while improving the structure of the existing planar heating element and applying to the blind, in addition to the window opening and closing function of the blind uniform from the blind The heat dissipation of the temperature distribution is related to the planar heating element blinds to be used together with the effects of decoration and heating.

Curtains mounted on a window to selectively block light include opening and closing the window while moving in the vertical direction and opening and closing the window while moving in the horizontal direction.

In the former, so-called line blinds, roman shades, and roll screens are known. The line blind refers to opening and closing a window while moving up and down after several line layers rotatable in a fixed position are horizontally arranged and integrally connected to separate lines. In addition, the roman shade means that the lowermost curtain cloth is gradually rolled up and rolled upward. In contrast, a roll screen refers to opening and closing a window by winding or unwinding the curtain cloth on the rotating shaft by rotating the rotating shaft while the one end of the curtain cloth is fixed to the rotatable rotating shaft.

The latter includes general curtains which are integrally manufactured with curtain cloth, and so-called vertical blinds which are separated by a plurality of curtain cloths in a vertical direction and connected by ropes. The blind to be described below will be described as a name encompassing line blinds, roman shades, roll screens, and vertical blinds.

On the other hand, the common planar heating element that generates electricity by applying heat is widely used as a residential heating device such as an apartment or a general house because it does not pollute the air and is not only sanitary but also easy to control its temperature and has no noise.

In addition, the heating of commercial buildings such as offices and shops, industrial heating devices such as workshops, warehouses, barracks, and various industrial heating devices, agricultural equipment such as vinyl houses and agricultural product drying systems, and melting snow or preventing freezing of roads and parking lots In addition to various freeze protection devices that can be used, it is also used for leisure, cold protection, home appliances, anti-fog of mirrors and glass, health supplement, livestock.

As a heat generating source of such a planar heating element, a heating line such as nichrome is used according to the prior art. However, in the planar heating element made of a heating wire such as nichrome, since electricity flows continuously through the line, when any part of the heating line is short-circuited, the planar heating element cannot be used because electricity is not energized.

In addition, in the conventional planar heating element using a heating wire such as nichrome, when the heating wire is short-circuited, there is a risk of fire because the electrical resistance in the corresponding portion is greatly reduced and generates severe heat. Thus, in order to prevent the short circuit of the heating wire, the insulation of the surface of the heating wire or between the heating wires is completely insulated by an electric conductor having a sufficient thickness. There is a disadvantage.

In addition, since the planar heating element using a heating wire such as nichrome has a structure in which only a corresponding portion of the heating line generates heat, there is a problem in that the temperature distribution of the planar heating element is uneven.

In addition, the planar heating element used in the past has a structure that is actually vulnerable to the waterproof, there is a defect that can not be easily used in the presence of water or moisture.

Accordingly, the present applicant solves the above problems by improving the structure of the existing planar heating element while using various advantages of the planar heating element, and by applying it to the blind, the heat of the uniform temperature distribution from the blind in addition to the window opening and closing function of the blind It has led to the development of blinds for planar heating elements that can be diverted and use the effects of decoration and heating together.

Therefore, the object of the present invention, while utilizing the advantages of the planar heating element by improving the structure of the existing planar heating element applied to the blind, in addition to the window opening and closing function of the blind can be a uniform temperature distribution heat from the blind It is to provide a blind for a planar heating element that can be used together with the effect of decoration and heating.

The planar heating element blind according to the first embodiment of the present invention has a blind unit 80 and a planar heating element 50 provided in the blind wings 83a to 83c of the blind unit 80. Indeed, the present invention has a window opening and closing function by a plurality of blind wings 83a to 83c, and has a function of dissipating heat of a uniform temperature distribution due to the planar heating element 50 provided in the blind wings 83a to 83c. . Therefore, the present invention has the advantage that can be used together with the effect of decoration and heating.

As shown in FIGS. 1A and 1B, the blind unit 80 includes a frame 81 fixed to a ceiling, an operation bracket 82 provided on one side of the frame 81, and a frame 81. Blind wings 83a-the ends of which are suspended on a plurality of carriers (not shown).

The wings 83a to 83c are moved. Therefore, each of the blind wings 83a to 83c is superimposed while moving along the longitudinal direction of the frame 81 ("A" direction in FIG. 1B).

At this time, in order to easily stack each of the blind wings 83a to 83c, each of the blind wings

The phase difference of 83a to 83c should be different from each other, and each blind wing in the frame 81

Individual guidelines 86a-86c (see FIGS. 2A, 2B) to which 83A-83C can move should be provided.

On the other hand, blinds are classified into manual and automatic according to the driving method, and may be classified into a fixed latch method, an elastic release method and a gear method, etc., depending on the operation method. Idea can be fully applied.

For reference, the fixing clasp method, the elastic release method and the gear method will be briefly described with reference to FIGS. 2A to 2C as follows.

As shown in FIG. 2A, the fixed clasp method refers to a structure in which the blind blade 83a can be manually moved along the frame 81a by the clasp 87a provided in the frame 81a. Of course, the wire (L) for supplying electricity to the planar heating element 50 will be disposed in the frame 81a, as shown in the above guidelines 86a ~.

As shown in FIG. 2B, the elastic release method refers to a structure in which a spring-type electric wire S coated in a PVC pipe 87b provided in the frame 81b is provided. At this time, as shown in the spring-type wire (S) to enter and exit, the opening 87b is formed on one side of the PVC pipe 87. Of course, the above-described guidelines 86a to 86c may also be provided in the frame 81b.

In contrast, the gear system refers to a rack 88 in which the rack tooth 88a is formed in the frame 81a, and a pinion 89 in which a pinion gear 89a for engaging the rack 88 and moving the rack 88 is formed. Refers to a structure consisting of). Of course, the pinion 89 is to move the rack 88 while operating by a separate motor, thereby moving the blind blade (83a).

Meanwhile, since the blind unit 80 shown in FIGS. 1A and 1B is typically installed in a window or the like, the blind unit 80 serves to shield summer sunlight or prevent winter drafts and moisture generation. However, the conventional blind unit did not have any function other than this role, but the blind unit 80 of the present invention, in addition to this basic function, an additional function that can dissipate heat of a uniform temperature distribution to play a role of heating. Have more

To this end, the planar heating element 50 is provided on the blind wings 83a to 83c. Of course, in order to provide the planar heating element 50 inside the blind wings (83a ~ 83c), the blind wings (83a ~ 83c) formed in the upper and lower wings (83a ', 83a ") along the thickness direction or , Inserting portion (not shown) for inserting the planar heating element 50 is to be formed, but below the blind blades (83a ~ 83c) in the thickness direction along the upper and lower wings (83a ',

83a ") will be described.

3, the planar heating element inside the upper and lower wing parts (83a ', 83a ")

If 50 is mounted, the upper and lower wing portions 83a 'and 83a "are joined to each other, and are finished with a rim finish material (not shown) to prevent water or moisture from entering the planar heating element 50. At this time, it is convenient to use the edge finish material which is biased.

In addition, the power supply line 70 for supplying power to the planar heating element 50 to be described later may be connected to an outlet after adopting any of the methods of FIGS. 2A and 2B, or a separate power supply unit 71. It can be placed so that the electricity is supplied to the planar heating element 50 by the power supply unit 71. Of course, the latter would require the power supply 71 to be a rechargeable battery, which is advantageously disposed and concealed inside the frame 81.

Meanwhile, as shown in FIGS. 3 and 4, the planar heating element 50 is disposed on one surface of the carbon fiber heating paper 10 in a state where the planar heating element 50 is spaced apart from each other. The pair of electrodes 30a and 30b for applying electricity to the 10 and the carbon fiber heat generating paper 10 and the pair of electrodes 30a and 30b are enclosed from the outside while the joints are hermetically compressed to each other. It consists of an insulating member (20).

In addition, the insulating member 20 includes an upper portion 20a and a lower portion 20b disposed on upper and lower surfaces with the carbon fiber heating paper 10 interposed therebetween, and the material is formed of a polymer insulating material.

For reference, the polymer material is, for example, polyester, acrylic, ABS, cellulose, carbon fluoride, polyethylene, polypropylene, polystyrene, rubber, polyvinyl chloride (PVC), polyvinyl fluoride, polyamide, polyimide, It refers to a large compound of extremely high molecular weight (usually 10,000 or more) such as urethane, epoxy, epoxy resin impregnated glass fabric.

Although high molecular compounds have various structures and properties, they are roughly classified into organic polymer compounds and inorganic polymer compounds, which are further divided into natural polymer compounds and synthetic polymer compounds. Glass or artificial dogs are processed into natural products and can be said to belong to an intermediate being.

Such polymer compounds are applied to plastic and various textile products, synthetic rubber products such as tires and tubes, safety glass, adhesives, paints, building materials, pipes, various vessels, insulating materials, electrical and electronic products, and the like.

Thus, in the present invention, the insulating member 20 of the planar heating element 50 is formed by using a polymer compound having such characteristics, among which urethane and epoxy are used.

For example, if the planar heating element blind is used for low temperature (about 80 ℃ or less), it is preferable to form the insulating member 20 using urethane, and if used for high temperature (about 100 ℃ ~ 160 ℃) epoxy It is advantageous to form the insulating member 20 by using.

That is, the upper portion 20a and the lower portion 20b made of urethane or epoxy are disposed on the upper and lower surfaces with the carbon fiber heating paper 10 interposed therebetween, and the upper and lower portions 20a and 20b are joined to each other. What is necessary is just to form the thermocompression bonding part 40 for waterproofing.

At this time, if the insulating member 20 is made of urethane, the thermocompression-bonding part 40 may be formed by applying a pressure of 10 Kg / cm ² at a temperature of about 150 ° C. If the insulating member 20 is made of epoxy, the thermocompression part 40 can be easily formed by gradually applying a pressure of 190 Kg / cm ² from a low temperature to a high temperature at a temperature of about 160 ° C. for about 1 hour and 30 minutes. Can be.

When the thermocompression-bonding part 40 is formed in this way, since the joints of the upper and lower parts 20a and 20b are hermetically compressed to the outside, the planar heating element 50 can be used safely even in the presence of water or moisture. Will be. As well as blind wings (83a ~

83c) It also has the advantage of being double safe against water and moisture because it is waterproof.

Meanwhile, as illustrated in FIG. 4, the carbon fiber heating paper 10 provided in the insulating member 20 is formed on the pulp member 2 and the pulp member 2 to form a pair of electrodes 30a and 30b. It is made of carbon fiber 1 that generates heat by a power source applied by

Of course, when manufacturing the carbon fiber heating paper 10, it is preferable to closely arrange the carbon fiber 1 in the pulp member 2 at regular intervals, as shown in Figure 4, the carbon fiber 1 In manufacturing, a relatively dense portion 6 and a low density portion 5 may be arbitrarily formed.

The carbon fiber 1 is a fiber made by heating and carbonizing an organic fiber in an inert gas, and raw materials such as cellulose, acrylic fiber, vinylon, and pitch are used. Molecular arrangements and crystals change depending on the raw materials used or the processing temperatures. In general, hexagonal rings of carbon form a layered lattice successively, and have a metallic luster and black or grey.

Strength 10-20 g / d, specific gravity 1.5-2.1. Excellent heat resistance and impact resistance, resistant to chemicals and high resistance to pests. Molecular weights such as oxygen, hydrogen, nitrogen, etc. are lost during the heating process, and thus the weight is reduced.

Due to these characteristics, carbon fiber (1) is used for sports goods (fishing rods, golf clubs, tennis rackets), aerospace industry (heat-resistant materials, aircraft fuselage), automobiles, civil construction (light weight materials, interior materials), electrical and electronics (antenna) ), It is widely used as a high performance industrial material in various fields such as environmental industry (air purifier, water purifier).

Thus, by uniformly dispersing the carbon fiber 1, which is much longer than its diameter and having a diameter of 5 to 50 μm and a length of 0.5 to 20 mm, in the pulp member 2, uniform heat generation is possible on the entire surface of the planar heating element 50. will be. Therefore, it is possible to solve the nonuniform temperature distribution due to the partial heating of only the heating line portion, which is a problem of the conventional planar heating element 50 using heating lines such as nichrome.

In addition, since the carbon fiber (1) is much easier to contact with each other than the carbon black powder of the particle shape during dispersion, it is possible to change the content of the carbon fiber (1) to be dispersed in a much wider range, thereby providing various It is possible to manufacture the planar heating element 50 having.

In order to manufacture the planar heating element blind having such a configuration, first, the carbon fiber 1 is closely disposed and fixed to the pulp member 2 to produce the carbon fiber heat generating paper 10, and then the carbon fiber 1 can be contacted. A pair of electrodes (30a, 30b) is installed on the heat generating paper 10 so that it can be.

Then, the upper and lower portions 20a and 20b of the insulating member 20 are disposed to cover the carbon fiber 1 heat generating paper 10 and the electrodes 30a and 30b from the outside, and then the joints The thermal compression part 40 is formed by the method described above. After the planar heating element 50 is manufactured, blind vanes 83a to 83c are manufactured by disposing the upper and lower wing parts 83a 'and 83a "with the planar heating element 50 interposed therebetween.

After the planar heating element blinds are manufactured as described above, when a power source is applied to the pair of electrodes 30a and 30b through the power supply line 70, the carbon fiber 1 generates heat by applying the applied power source and heat of relatively high temperature. This heat is emitted to the outside through the insulating member 20 and transferred to the blind wings (83a ~ 83c), it can be used as a substitute for the heater.

Therefore, if the blind is used in winter, there is an advantage that can combine the effect of insulation and heating in addition to the effect of decoration.

Thus, according to the planar heating element blinds of the present invention, by utilizing the advantages of the planar heating element 50, by improving the structure of the existing planar heating element 50 applied to the blinds, in addition to the window opening and closing function of the blinds from the blinds The heat of the uniform temperature distribution can be dissipated, so that the effects of decoration and heating can be used together.

On the other hand, in the above-described embodiment, the planar heating element 50 is provided inside the blind wings 83a to 83c of the horizontal movable blind unit 80.

However, as shown in FIG. 5, the planar heating element 50 can be sufficiently applied to the respective blind wings 183a to 183c of the vertically movable blind unit 180.

When the vertical movable blind unit 180 shown in FIG. 5 also pulls or loosens one side of the ball chain 185, each of the blind wings 183a to 183c is formed due to the rotation shaft provided in the frame 181. Fold up from the bottom. Therefore, according to the use of the vertically movable blind unit 180 of FIG. 5, the ball chain 185 can be properly moved and used.

As described above, according to the present invention, by utilizing the advantages of the planar heating element while improving the structure of the existing planar heating element applied to the blind, in addition to the window opening and closing function of the blind heat of the uniform temperature distribution from the blind It is possible to provide a blind for the planar heating element that can be used together with the effect of decoration and heating.
