Description

Lamp heater with bandage spring form of woven carbon fibers}

The present invention relates to a carbon yarn lamp heater, which is formed by weaving carbon (carbon) yarns with a weft yarn and a warp yarn, cutting the heat-resistant ceramic coating on a surface to a certain width, and winding them in the shape of a polygonal coil spring to form an arc shape. The fixed terminal is fixed with a fixed terminal for pressing, and the fixed terminal fixes one end of the heat resistant intermediate terminal to the terminal piece protruding in the radial direction of the central axis of the vacuum sealed container, and the other end of the heat resistant intermediate terminal connects the lead wire. It relates to a woven carbon yarn lamp heater configured to be spot welded.

In general, a lamp is also called a light bulb, and a light generated by heating a high temperature by flowing a current through a filament installed in the inside of a vacuum tube may be used, or as a lamp for a heater using heat that generates heat as needed. This may illustrate a configuration in which a filament is installed inside the vacuum state and a terminal connected to the filament is installed at both ends of the glass tube. In addition, when a tungsten platen is installed along the axis of the glass tube and the iodine gas is enclosed in the tube to send a current to the filament (when power is applied), the tungsten atoms generated in the filament are combined with iodine in the tube wall to become tungsten iodide and return to the filament, Here, it is used as a high efficiency lamp that can be used for a long time by a so-called iodine cycle that decomposes and leaves tungsten in the filament.

However, this type of lamp has a problem that the damage of the filament is weak to external impact, the durability is weak due to deformation of the shape due to heating, etc., there is a burden such as the cost of installing the coil.

On the other hand, carbon yarns used for surface heating elements and the like use carbon fiber bundles of fine thickness as a group. For example, if the carbon fiber consists of 26400 pieces, the resistance is about 60 ohms when the length is 1 meter and the diameter is 0.3 mm. Therefore, based on this design the desired output (watt) to produce a planar heating element. Of course, in this case, the resistance Where R is the resistance, rho is the resistivity, l is the length, and s is the unit area. However, these are used as a heat generating source of the planar heating element is mainly designed to dissipate the temperature of about 50 to 70 degrees, if there is a risk of fire, it is oxidized with air and the durability is significantly reduced.

On the other hand, a heater incorporating a carbon yarn as a heat source was developed in a vacuum tube. The carbon yarn is fixed in a bundle to provide a desired output, and the technology of fixing the carbon yarn to the terminal and the technology of focusing the carbon yarn. Due to this shortcoming, industrialization has been difficult. An example of such a technique is known as a carbon-based heating element disclosed in Japanese Patent Application Laid-Open No. 2000-123960, which has a cap-type electrode part 2 at both ends of the carbon-based heating element 1 as shown in FIG. 1. ) And the cap-shaped electrode part 2 are built in the vacuum-sealing container 3, and the cap-shaped electrode part 2 is made to connect the lead wire 4 to apply power. As shown in FIG. 2, the lead wires 4 form a fixed shape in which the outer periphery of the bundle of carbon-based carbon yarns 6 composed of a plurality of bundles is wound with a carbon chamber 7 to form a carbon flux 5.

FIG. 3 is an exemplary view configured to provide a bundle of carbon yarns 6 necessary in this case. Each of the three strands wound around a certain bundle of carbon yarns 6 with a carbon yarn 7 and wound with a carbon yarn 7 is shown. The carbon body 5 of the structure which winds together with the carbon chamber 7 'and makes it integral is shown.

That is, both ends thereof are formed by using a unit carbon body 5 as shown in FIG. 2 or a heating element 1 made up of a plurality of carbon bodies 5 wound with a carbon strand 7 'as shown in FIG. 3. It is molded to cover the vacuum sealing container (3) by coupling to the electrode portion (2) in the form of a cap.

However, this method uses the desired number of bundles of desired carbon yarns (6) to create the desired resistance value to use the desired output (W), but the hassle of having to bind the carbon yarn (6) to the carbon chamber (7), If necessary, there is a problem such as impregnating the liquid resin as necessary so that the bundled carbon chamber 7 is not peeled off.

On the other hand, instead of increasing the number of strands as a way to increase the output was proposed a way to increase the output by increasing the length, which is known as Japanese Patent Application Laid-Open No. 2002-63870 (US Patent Publication No. 2001 / 0055478A1). This can be illustrated as shown in Figure 4, the both ends of the vacuum sealing container (3) to the lead wires 4, the both ends of the vacuum sealing container (3) to the fixed terminal 3-1 for fixing the lead wire (4) ) And the electrode piece 4-1 which is placed so as to be conductive, and the coil band-shaped carbon filament 10 is provided with a space holder 11 at a predetermined length so as to be supported on the inner wall of the vacuum hermetic container 3. . Both ends of the carbon filament 10 is provided with a fixed terminal 20 having a power supply sleeve 20-1, the fixed terminal 20 is a sleeve 20-1 and the sleeve 20-1 It is configured to include a connecting piece 20-2 is integrally coupled to the intermediate terminal 20-3.

In one embodiment of the fixed terminal 20, the connecting piece 20-2 bent in a step shape as shown in FIG. 1) and a graphite paper 20-4, which is placed in the space of the sleeve 20-1 and the connecting piece 20-2, and functions to surround the coiled carbon yarn filament 10. .

Another embodiment of the fixed terminal 20 is a cylindrical sleeve 20-1 and the coil-shaped carbon yarn filament is placed in the inner diameter of the sleeve 20-1, as shown in FIG. 10), the inner and outer graphite paper 20-4 and 20-41 surrounding the inner and outer portions of the carbon yarn filament 10, and the graphite paper 20-4 inside the inner graphite paper 20-4. And an inner sleeve 20-5 for fastening the carbon filament 10 with the elastic force toward the inner diameter portion of the sleeve 20-1 with an elastic force, and from the center to the end of the inner sleeve 20-5. It consists of a connection piece 20-2 which extends and connects with the intermediate terminal 20-3.

However, such a technique is to perform the function of simply fixing the carbon filament 10 to the intermediate terminal 20, so that the function of positioning the center of the vacuum hermetic container 3 is weak so that a separate space holder 11 is installed. There is a problem to be done. And the structure of Figure 5 is simply bent to secure the carbon filament (10) is difficult to be fixed in place when the bending holding force is weakened durability is weakened, the structure of Figure 6 is placed in the inner diameter of the cylindrical sleeve Since it is a way to make it easy to be separated during the impact, there is a problem inferior workability. In addition, since the carbon filament 10 is formed in a band shape by arranging the carbon yarns in a predetermined width, the binding strength between the carbon yarns is weak, so that the carbon yarns forming the carbon yarns during impact or long-term use are separated from each other and the durability is weakened. have.

In addition, since the shape of the carbon filament is a spring shape, when the carbon filament is in contact with the inner wall of the vacuum airtight container 3 due to elongation or impact, the contact area is increased and the heat is transferred to the inner wall to overheat, thereby deteriorating durability. There is this.

The present invention is to solve this problem, the object of the present invention is to use a carbon yarn (carbon yarn) used as a planar heating element as a heating source, weaving the carbon yarn in a weft and warp and ceramic coating cut to a certain length and width It is to provide a woven carbon yarn lamp heater that has improved the durability by forming a wound form in the shape of a polygonal spring to make a point contact with the inner wall of the vacuum sealed container rather than a surface contact.

Still another object of the present invention is to provide a woven carbon yarn lamp heater that has a light transmitting property by extending the life of the vacuum glass tube by attaching a getter for gas purification to a fixed terminal for fixing the carbon body.

To this end, the present invention is a carbon body woven carbon yarn in a weft and warp yarn, cut the ceramic coating cut to a certain length and width to achieve the desired resistance value, and wound around a multi-rod rod to form a polygonal coil, both ends of the carbon body is heat-resistant It is fixed with fixed terminal, but the fixed terminal has a terminal piece bent in the center axis of the vacuum glass tube so that the heat-resistant middle terminal is always connected to the connecting piece for fixing the lead wire in the center of the central axis, so that the heat transfer is constant so that the heat transfer to the external lead wire A woven carbon yarn lamp heater is constructed to be uniform.

The present invention also attaches a gas purification getter to the fixed terminal for fixing the carbon body to purify the gas caused by the heating of a single substance to enable life extension.

12 is a table showing an example of the number of strands and the resistance value of the carbon yarn carbon body used in the present invention.

The carbon yarn carbon body used in the present invention was installed in a vacuum glass tube (vacuum airtight container) to be able to withstand high heat, which was used in a plane heating element, and can be used as a carbon yarn lamp heater for an electric stove. As described above, the required output (watt) can be designed using the principle of the difference in resistance value according to the number of strands, and the extension of the length increases the resistance value, and the increase in the number of carbon yarns decreases the resistance value.

That is, if the output is 60 ohms and the power is 220 volts, ) Therefore, if the length is shortened or the width (the number of carbon yarns) is adjusted with the basis of such output, various lamps of the same output can be manufactured by adjusting the length of the glass tube of the lamp. In fact, it was confirmed that heat was generated at 700 to 900 degrees, and the conditions sufficient for use as a heater were satisfied. This is because the interior of the vacuum sealed container (3) is a vacuum, the oxidation is blocked by the source, it is determined that the desired output can be provided by adjusting the resistance value according to the length or the number of carbon yarn.

Another feature of the present invention is a configuration using the intermediate terminal (20-3), which forms a fixed terminal 40 on both ends of the carbon body 30 and the fixed terminal to maintain the binding force of the carbon body 30 The heat generated by the poor contact between the sieve 30 and the intermediate terminal 20-3 is reduced to reduce the heat generated at the contact portion with the terminal, and by simply pressing the arc-shaped cover plate 41 by pressing, It secures the end, which eliminates the need for a separate machining step, improving productivity.

In the present invention, the intermediate terminal 20-3 and the lead wire 4 form a structure connected to each other through the electrode pieces 4-1 having a predetermined size, and the heat-resistant intermediate terminal 20-3 and the electrode pieces 4-4. 1) is made of molybdenum, the lead wire 4 is preferably composed of tungsten, because the melting temperature of molybdenum is 2600 degrees Celsius, tungsten is high 3387 degrees Celsius.

In manufacturing the present invention, weaving the carbon yarn (6) constituting the carbon body 30 into the weft yarn 31 and the warp 32, and weaving, as shown in Figure 8 to form a ceramic layer 33, as shown in Figure 7 Cut and set the width and length to have this resistance. Then, the cut carbon body 30 is wound on a polygonal rod (not shown) having a predetermined diameter, and is heated at about 1000 to 1200 degrees around the rod to harden the ceramic layer and at the same time set in the form of an angled coil spring. Cut to length. Then, the angular fixed terminal 40 is fixed to both ends of the cut carbon body 30 in the same manner as in FIGS. 9 to 11, and then the intermediate terminal 20-20 is connected to the terminal piece 42-2 of the fixed terminal 40. Weld 3). Of course, in this case, one end of the intermediate terminal 20-3 is fixed by spot welding the electrode piece 4-1 having the lead wire 4 connected in advance. Then, if necessary, the getter assembly 50 is spot welded together to the fixed terminal 40 together.

The prefabricated product is placed in a circular pipe (with a vacuum suction tube as well as a pipe in the middle of the length) in a state in which both ends are opened, and both ends are pressed closely by heating the both ends at 1800-2000 degrees Celsius as shown in FIG. 9. Formed flat terminal portion 3-1, and the center is molded to maintain the space as it is. In particular, the present application adopts a method of using the heat-resistant intermediate terminal 20-3, so that the electrode piece is large even if the space area due to the lead wire 4 is wide when the vacuum is made after compression after cooling to form the flat terminal portion 3-1. (4-1) is thin and improves adhesiveness so that it can continue to block the outside air when vacuum is achieved. In addition, the use of the heat-resistant intermediate terminal 20-3 is to prevent the carbon body 10 exposed to oxygen from being oxidized and directly heated when heating the end of the glass tube to form the planar terminal portion 3-1. . That is, the heat to be heated is first applied to the intermediate terminal 20-3 (the melting temperature of molybdenum is 2600 degrees Celsius, so that the glass tube has heat resistance even when heated to 1800-2000 degrees Celsius). Prevents this from being delivered and increases the production yield. Of course, when the shaping of the flat terminal portion 3-1 is completed, the inside air is sucked through the auxiliary pipe for forming a vacuum (not shown) to create a vacuum, and then cut and blocked to complete the vacuum sealing container 3.

In addition, the present invention fixed the getter assembly 50 to the fixed terminal 40 by welding, etc. When the power is applied through the lead wire 4, the carbon body 30 is heated to generate heat, foreign matter of the carbon body during heating Even if the degree of vacuum decreases due to the combustion of the foreign matter, the zirconium sintered body has a gas purification function, which provides the effect of maintaining the clean state and extending the life of the lamp. Economic loss caused by lamp breakage or damage can be prevented.

In addition, the subject innovation of the present invention is that the carbon body 30 to form a polygonal coil spring shape of the triangular or quadrangular or more as shown in Figs. 9 and 10, which is a vacuum sealed container (3) due to the vibration or sagging due to the characteristics of the polygonal shape. ) Durability is improved by reducing direct heat transfer to the vacuum sealer even though there is contact with the inner wall at the vertex.
