Desk heater for plane heater {Desk heater for plane heater}

The present invention relates to a desk heater 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 it for the desk heater, the heat of the uniform temperature distribution is improved. The present invention relates to a desk heater for a planar heating element which can be diverted and thus serves as an effect of decorative and auxiliary heating.

In recent years, it is well-heated, so it may be easy to study or work at school or at work. However, even in a cold winter, even in a well-heated office or school, when you actually study or work at your desk (desk), you can see that your knees are not warm enough.

Thus, in the case of older adults or women, there are many examples of using a portable heater for intensively keeping only localized areas of the body.

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 has an advantage that it does not pollute air and is hygienic, its temperature control is easy, and there is 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.

Therefore, 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 can be used as an auxiliary heating device at the desk by applying it for desk heater and at a uniform temperature. It has led to the development of a desk heater for a planar heating element that can dissipate the heat of the distribution so that it can serve as a decoration and heating effect.

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 and applying it for desk heaters, the heat of a uniform temperature distribution can be dissipated so that the effect of decoration and auxiliary heating It is to provide a desk heater for one surface heating element to serve.

Hereinafter, with reference to the accompanying drawings will be described in detail for each embodiment of the present invention.

1 is a perspective view of a desk equipped with a planar heating element desk heater according to a first embodiment of the present invention, FIG. 2 is a planar heating element desk heater mounted on the desk of FIG. 1, FIG. 4 is a plan view of the carbon fiber heating paper of the desk heater for the planar heating element shown in FIG.

As shown in these drawings, the planar heating element desk heater 100a according to the first embodiment of the present invention can be mounted on the desk 80 shown in FIG. It may be disposed at the inner front surface 80a of the 80.

As shown in FIG. 2, the planar heating element desk heater 100a includes a heater body portion 90a, a planar heating element 50 provided in the heater body portion 90a, and a heater body portion 90a. The deodorizing member 92a mounted to the opening and disposing the heat dissipation cover 91 for dissipating heat from the planar heating element 50 to the outside and the heater body portion 90a on the inner front surface 80a of the desk 80 is provided. Have

Looking at the first embodiment, it can be seen that the heater body 90a is a frame and the heat dissipation cover 91 is formed of an epoxy material. As a result, the heater body portion 90a introduced in the first embodiment has a shape similar to that of a general picture frame.

According to this first embodiment, in addition to the effect of heating heat, there is an advantage that can serve as a decorative effect as a picture frame. Therefore, it will be advantageous to form a separate decorative pattern on the heat dissipation cover 91. Although not shown, the decorative pattern may be a picture, a photo, or a transfer.

When the heater body portion 90a is a frame, the collecting member 92a is a velcro as a means for causing the heater body portion 90a to hang on the inner front face 80a of the desk 80. Therefore, there is an advantage that the heater body of the first embodiment of the frame frame can be attached to the inner front surface 80a of the desk 80 very easily.

However, in addition to this method, after attaching the hook to the inner front (80a) of the desk 80, there is also a method of providing a hook (not shown) on one side of the heater body (90a) to be hooked to the hook. It may be an embodiment of.

On the other hand, as shown in Figure 2, the outside of the heater body portion 90a of the frame is mounted with a power line 85 extending through the heater body portion 90a to the outside, the power line 85 The end of the plug is provided with a plug 86 detachably coupled to the outlet (not shown).

The line of the power supply line 85 is provided with a temperature controller 88 for controlling the temperature from the planar heating element 50 including the on / off operation of the planar heating element 50. Thus, in the state where the plug 86 is plugged into the outlet, the user has an advantage of easily turning on / off the temperature of the planar heating element 50 or adjusting the temperature through the temperature controller 88.

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 desk heater (100a) is used for low temperature (about 80 ℃ or less), it is preferable to form the insulating member 20 using urethane, high temperature (about 100 ℃ ~ 160 ℃) If used as it is advantageous to form the insulating member 20 using the epoxy.

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. In addition, since the blind wings (83a ~ 83c) is also waterproof, there is an advantage that double safety against water or moisture.

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 in the entire surface of the planar heating element 50 is achieved. It becomes possible. 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 more easily contacted with each other than the carbon black powder of the particle shape during dispersion, it is possible to change the content of the dispersed carbon fiber (1) in a much wider range, so that various heat generation characteristics It is possible to manufacture the planar heating element 50 having.

In order to manufacture the planar heating element desk heater 100a having such a configuration, first, the carbon fiber 1 is closely disposed on the pulp member 2 to fix the carbon fiber heating paper 10, and then the carbon fiber 1 ), A pair of electrodes (30a, 30b) is provided on the heat generating paper (10) to be in contact with.

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, the planar heating element 50 is placed in the heater body portion 90a which is a frame, and the opening is closed by the heat dissipation cover 91.

Then, the velcro hanging member 92a is used to crush the inner front surface 80a of the desk 80. In this state, when electricity is supplied to the planar heating element 50 through the power supply line 85 and is applied to the pair of electrodes 30a and 30b, the carbon fiber 1 generates heat at a relatively high temperature by the applied power source. This heat is emitted to the outside through the insulating member 20 and eventually transmitted to the outside through the heat dissipation cover 91, it is possible to perform a sufficient role as an auxiliary heater.

Therefore, if the desk heater (100a) is mounted on the desk 80 in winter, it is possible to provide an additional effect of the decorative effect in addition to the effect of heat.

On the other hand, in the planar heating element desk heater 100a of the first embodiment described above, the heater body portion 90a is used as a frame. However, as shown in FIG. 5, in the planar heating element desk heater 100b of the second embodiment, the heater body 90b may be a horizontal foot plate. Foot plate is to get the heat by placing the soles of the feet.

As such, when the heater body 90b is a horizontal foot plate, the collecting member 92b may be a plurality of legs supporting the horizontal foot plate. By way of example, a predetermined wire mesh 89 may be further disposed on the plate surface of the horizontal foot plate. Of course, the power line 85, the plug 86 and the temperature controller 88 described above may be configured in the same manner as in the first embodiment and used the same.

On the other hand, in addition to the above embodiment, the heater body portion 90c in the planar heating element desk heater (100c) shown in the third embodiment of Figure 6 may be a stand-type heating plate. Of course, even in this case, the collecting member 92c may be a plurality of legs supporting the stand-type heating plate. In addition, the power line 85, the plug 86, and the temperature controller 88 described above may be configured in the same manner as in the first embodiment and may be used in the same manner.

As described above, according to the present invention, while utilizing various advantages of the planar heating element, by improving the structure of the existing planar heating element and applying it for desk heater, the heat of uniform temperature distribution can be dissipated, thereby decorating and auxiliary heating. A desk heater for a surface heating element is provided to combine the effects of.
