Description

[Detailed description of the invention] The present invention relates to a heating heat insulator using a reticular circuit.

Conventionally, heating and insulation using heating wires over a wide area was the first.
As shown in Figures 1 and 2, single heating wires were arranged in a meandering manner within a plane or in a spiral manner. However, with this method, if the heating wire breaks, heating cannot be performed without conduction, and because it is a wire, there is a limit to the capacity of the conduction current, so low voltage and high current heating and heat retention are not possible. It was not suitable.

In order to overcome the conventional system, the applicant invented a heat insulator in which several sets of heating wires 2 are woven parallel to one piece of cloth 1 as shown in Fig. 2, and filed an application with the Imperial Office. In this method, one of the heating wires
Even if one part is disconnected, heating continues because the other heating wires are conductive, and it can be adapted to heating and heat retention using low voltage and high current.

However, with this method, the heat is easily concentrated in the cloth, and the area around the heating wire is three-dimensional! It is unsuitable for heating and keeping warm on a large scale, and a large amount of fabric is required for large-scale heating and keeping warm, which is uneconomical. The present invention aims to solve all the problems of the conventional methods at once.

The structure of the present invention is constructed by forming the heat gauze into a net shape. Also, as shown in Fig. 6, wire-shaped terminals 2 are provided on opposite sides of the network circuit to be commonly connected to each heating wire 1.
If the heating wire is connected, current will flow almost uniformly through the heating wire.For example, steel wire, nichrome wire, etc. are used as the conductive wire that makes up the heating wire, but in the case of low voltage and high current, steel wire is used. The line is appropriate.

For individual heating wires, it is possible to use conductive wires as they are, but in order to make the entire circuit freely deformable, as shown in Figure 4, conductive wires are formed around heat-resistant synthetic resin threads in a spiral shape. It is effective to use a wound wire.

According to the heating and heat insulating device of the present invention, since the circuit is made up of a plurality of heating wires crossing each other, it is natural that even if there is a partial wire breakage, the heating and warming can continue as in the case of a parallel circuit. be.

Moreover, compared to the method in which the heating wires are woven into cloth, since the heating wires are exposed to the outside, the heating and heat retention efficiency is much better, and it is economical because there is no need to use cloth.

The heating/warming device of the present invention can be placed on the bottom of a bathtub to heat and keep warm water as shown in Figure 5, to heat and keep earth and sand warm as shown in Figure 6, and to general plating liquid pipes as shown in Figure 7. It is used for heating and keeping liquids warm, and heating for melting snow on roofs as shown in Figure 8.The contact area between the conductor and the object to be heated and kept warm is large, and the thermal efficiency is extremely good. At the same time, especially when the conductive wire is spirally wound around a synthetic resin thread as shown in Fig. 4, it is difficult to stretch, bend, etc.
Since it is deformable, it is extremely convenient to handle, and especially when melting snow as shown in Fig. 8, the roof tiles come into contact with each other according to the shape of the roof tile, and can produce good results.

Heating and heat insulating device 2 using a reticular circuit, Claim 3, Detailed Description of the Invention The present invention relates to a heating and insulating device using a reticular circuit. Conventionally, heating and insulation using heating wires over a wide area was the first.
As shown in Figure 1.2, a single heating wire was arranged in a meandering manner within a plane or in a spiral manner. However, with this method, if the heating wire breaks, it will not conduct electricity and heating will not be possible, and since it is a single wire, there is a limit to the carrying current capacity, so it is not suitable for heating and keeping warm with low voltage and high current. there were. In order to overcome the conventional system, the applicant invented a heat insulator in which a plurality of heating wires 2 are woven in parallel to a single piece of cloth 1 as shown in FIG. 2, and filed an application with the Imperial Office. In this method, one of the heating wires
Even if one part is disconnected, heating continues because the other heating wires are conductive, and it can be adapted to 7Vk vortices caused by low voltage and high current. However, with this method, &'ν tends to concentrate in the cloth, making it unsuitable for uniformly heating and keeping the area around the heating wire three-dimensionally, and also requiring a large amount of fabric for large-scale heating and keeping warm. This is uneconomical, and the elasticity of the surface itself is insufficient. On the other hand, a technique for obtaining a planar heating element by interweaving non-conductive fibers and thin metal wires is also known (see, for example, Japanese Utility Model Publication No. 38-285835). Even in this method, metal wires are woven directly into the fabric, which results in insufficient stretchability and flexibility in bending, making it surprisingly inconvenient to handle. It is an object of the present invention to overcome the following two drawbacks of the conventional example and to provide a heat insulator that is highly elastic and bendable, and yet has good thermal efficiency. In the present invention, "C" is a heat-retaining material (M+) In order to make the device itself highly elastic and bendable, metal wire is not used as it is, but a thread blended with non-conductive fibers such as gold and conductive wire is used. Convex 1 in FIG. 6 shows an embodiment in which a heating wire 111 is wrapped around a non-conductive fiber 112, and 2 in FIG.
An example will be shown in which the tunic fiber 112 is combined with
The present invention is not limited to these examples. The conductive wire constituting the heating wire may be, for example, a steel wire or a Nitarom wire, but in the case of low voltage and high current, a steel wire is suitable. Further, the yarn 11 thus obtained is formed into a net shape, and common terminals 12 are provided on opposite sides to be connected to each heating wire.
By providing 13, the heating/warming device 1 of the present invention is formed. The shape of the net may be either a rhombus as shown in 1 in FIG. 4 or a hexagon as shown in 2 in FIG. Also common terminal 12.16
can be either one conductor or multiple conductors. With this configuration, firstly, a current flows through each heating wire from ki to -if through the common terminals 12 and 13, and uniform heating can be achieved over the entire narrow surface as shown in a). Second, since it is a circuit in which multiple heating wires intersect, even if there is a partial disconnection, just like in the case of a parallel circuit, MJ Heat Retention IIi!

Conventionally, heating and insulation using heating wires over a wide area was the first.
As shown in Figure 1.2? L-wire heating wires were arranged in a meandering or spiral manner in one plane. However, with this method, if the heating wire breaks, it will not conduct electricity and heating will not be possible.Also, since it is a single wire, there is a limit to the capacity for oil conduction current, so it cannot be heated and kept warm by low voltage and high current. It was not suitable. In order to overcome the traditional method, Vfi people are using a piece of cloth 1 as shown in Figure 2. (The heating wire 2 is connected in parallel to ξIN, and the heating C1 is connected to the common power supply terminal 3.
．． I left the A vessel. In this method, even if the - section of the heating wire is disconnected, heating continues because the other heating wires are conductive, and it can be adapted to a single crystal heater using low voltage and high current. However, with this method, heat tends to concentrate within the heating wire, making it unsuitable for heating and keeping the area around the heating wire in a three-dimensional manner, and requiring a large amount of fabric to heat and keep warm on a large scale. This results in a small economy, and the elasticity of the surface itself is insufficient. On the other hand, a technique is also known in which a planar heating element is obtained by assembling non-conductive fibers and thin gold wires in an intersecting pattern. However, even with this method, the metal wires are directly woven into the fabric, so the elasticity is insufficient and the fabric is not flexible in JJi bending, making it surprisingly inconvenient to handle. SUMMARY OF THE INVENTION An object of the present invention is to overcome the drawbacks of the conventional examples, and to provide a heat insulator that is highly stretchable, bendable, and has good thermal efficiency. In the present invention, there is no twist! A wire 11 is formed by intersecting a heating wire itt with bendable non-proprietary fibers 112 to form a net, and the threads 11 are formed at opposite ends of the net for connection to the heating wire 111. This is achieved by providing a plurality of bendable conducting wires 12 and 13. Here, as an example of intersecting the electric heating m1ll and the J1 conductive fiber 112, 1 in FIG. 3 shows a case in which they are twisted together, and 2 in FIG. The case where heating wire ill is wrapped around is shown. Below 1. The reason for using the thread 11 in which the heating wire 111 and the bendable non-conductive 1 [1 ftl 12] are intersected as in the example shown in FIG. Although it is necessary to use a wire that is sufficiently strong to make it flexible, if the net is made of only the heating wires 111, it will not have enough strength to withstand tensile stress. In addition, it is softer to the touch and easier to handle when interwoven with II'4'■ fibers. net 1,1
The pattern is diamond-shaped as shown in Figure 4.
A hexagonal shape as shown in the figure is possible, but the shape is not limited to these. 11i7. ! v! ! it 11t to L te ff Sti-J
t4t1. := riD A conductive wire 't can be considered, but it needs to be bendable and microscopic in order to generate heat as it is guided2, but it has low fatigue when bending and has remarkable tensile strength. Steel wire is more suitable for bJ. The bendable non-conductive fibers may include synthetic fibers such as nylon and vinyl, natural fibers such as cotton tubes, and IF fibers, but they must be highly heat resistant. To make the common feeding end-rl 2.13 bend 11,
Either it is necessary to use an extremely thin conductor wire, or a single conductor wire is difficult to bend, pull, etc. (it is easy to break due to stress, and there is a possibility that the electrical connection with the heating wire 111 will be insufficient). Therefore, as shown in Fig. 5, the thread 11 is connected to the 4W wire 8 using a plurality of bendable conducting wires. ).The heating insulator of the present invention can be placed at the bottom of a bathtub to heat and keep hot water warm, as shown in Figure fJS6, or placed in sand as shown in Figure 7. Used for heating and keeping farmland warm,
As shown in Figure 8, it is used for heating to prevent frost damage to agricultural crops.
It has a variety of uses, such as being used for heating and insulation to melt snow and make it fall off. The effects of the present invention are as follows. First, since the bendable thread 11 is used, the mesh body or the bendable thread can contact the surface of the object to be heated depending on the shape of the wire to conduct heat conduction, thereby improving thermal efficiency. Second, since heavy light flows through the common terminals 12 and 13 in a similar manner, there is no fluctuation in heating and heat retention. Thirdly, the heating wires 111 intersect in different ways, so 1:++
Heating and keeping warm can continue even if a wire break occurs. Fourth, since the heater is formed in a net shape, the expansion fN 4
It is economical because it is rich in lactic acid, is convenient to handle, and does not require cloth such as a heating insulator shown in Fig. 2. 4.
