Description

  The present invention relates to a tunnel-type ground surface or floor surface heating device, and more specifically, it has a simple construction, has good workability, is inexpensive, and has excellent economic efficiency, particularly for indoor and outdoor masses. The present invention relates to a tunnel type ground surface or floor surface heating device capable of effectively heating the ground surface or floor surface in a gathering area or building, and a plurality of the tunnel type ground surface or floor surface heating devices are connected. It is related with the large sized planar heating apparatus comprised as mentioned above.

Conventionally, a number of different technologies have been developed and generally put into practical use for heat-insulating and heat-retaining and warming a general basal plane including the ground surface and an indoor floor surface.
For example, as a technique for heating and insulating the floor surface in indoor rooms, particularly in detached houses and apartments, as commonly known as floor heating technology, plate, fiber layer, plastic layer or marble is used. An electric heating sheet that generates heat when energized is disposed on the lower surface layer portion of the surface layer portion that includes the stone layer, or an appropriate hollow tube is drawn in a zigzag manner between appropriate support layers, A method of arranging a plurality of adjacent block panel materials in which hot water or warm air is circulated in the hollow tube or a linear heating element that generates heat by energization is arranged in the same shape instead of the hollow tube. There are many parts that are known and need to be heated or kept warm if necessary on the surface of a large building or outdoor such as a factory or warehouse. And analogy Because it is dangerous to maintain the internal temperature of the factory or warehouse at a certain temperature, or the freezing condition occurs on the surface of roads, bridges or public facilities where the public gathers, There are many cases where it is desirable to control the temperature of the ground, the ground surface, and even the atmosphere at the desired temperature when the surface is heated and kept warm, or when growing a specific animal or plant. The base is mainly made of concrete, and an appropriate hollow tube is provided in the surface portion of the main body mainly composed of the concrete layer or inside thereof, and hot water, hot spring water, or hot air is circulated in the hollow tube. Alternatively, instead of the hollow tube, a planar heating element that generates heat when energized is arranged, or a linear heating element that generates heat when energized is arranged in a zigzag manner, and the concrete layer is mainly used. Do Techniques such as placing the heat generating member for generating heat by receiving an infrared or electromagnetic waves in the surface portion and the inside of the body portion is known.

Each of the above prior arts has individual characteristics, and has advantages and disadvantages in the use site, purpose of use, and obtained effects, but the simplicity of the structure, installation cost, Taking into consideration the running cost and controllability including maintenance and management, for example, JP 2001-003307 A (Patent Document 1), JP 2001-262507 A (Patent Document 2), JP 2003-114283 A, and the like. (Patent Document 3), Japanese Patent Application Laid-Open No. 2005-315063 (Patent Document 4), Japanese Patent Application Laid-Open No. 2014-202001 (Patent Document 5), etc. It is considered that the structure arranged in the above is desirable as a technique that can be used for the basic configuration of the tunnel type ground surface or floor surface heating device in the present invention.

However, in each of the above-mentioned known techniques, in order to effectively use a single linear heating element in a single large concrete block at a low cost, it is arranged in a number of locations in a zigzag manner. In consideration of the fact that the average effective active life of the linear heating element is about 5 years, the characteristic value of the linear heating element is reduced in several years. Since it is impossible to pull out only the linear heating element from the concrete block and replace it with a new linear heating element, it is necessary to replace each concrete block with a new heat-retaining heat-retaining concrete block. However, there is a drawback that the burden of economic costs is quite severe.

Further, in the conventional technique, since the surface of the linear heating element arranged in the concrete block has many places where it cannot uniformly contact the inner surface of the concrete portion, There is no compensation that ensures that all of the heat energy generated from the heat generation is transferred into the concrete block, and as a result, part of the heat energy generated from the linear heating element is wasted. There were also drawbacks.
Furthermore, in the above-described conventional example, only one linear heating element having a certain length is fixedly wired to one exothermic concrete block. Therefore, it can be used only for a single application, lacks versatility, and has a disadvantage of lack of diversity.
However, in the above-described conventional example, high manufacturing costs are required for the production of individual members, and the structure is complicated and heavy, making it difficult to increase the size, and running related to construction costs and maintenance management. The cost was high and there were many economic problems when increasing the size, making it difficult to realize industrially.

The surface layer portion of the outer surface is provided with a base material layer 45 or not through the base material layer 45, and further corresponds to an appropriate floor material made of a synthetic resin material having strength and heat dissipation effect. It is also a desirable example that the outer surface layer portion 46 is provided.
In general, the outer surface layer portion 46 is a member used as a floor material.
Furthermore, in the present invention, it is also possible to mount an earth and sand layer having an appropriate thickness directly on the outer surface surface portion of the ceiling portion 4 in the heat generating covering portion 5. The present invention can be applied to a part of the work place.

By the way, in the tunnel type ground surface or floor surface heating device 1 according to the present invention, as shown in FIG. 3, the tunnel type ground surface or floor surface heating device 1 is made of appropriate concrete or plywood material. It is to be used by being fixed to a basal plane portion 47 made of a flat surface formed of wood, plastic material, metal material or the like, which is basically fixed by pressure contact using an appropriate adhesive, Using the nail means 95, the tunnel type ground surface or the main body portion of the floor heating device 1 is nailed and joined from the upper side of the outer surface portion or from the side wall portion to the oblique direction of the main body portion. It is to be fixed.
Further, when the basal plane portion 47 is made of concrete, it is desirable to form an adjustment surface in which a mortar layer is formed on the upper surface of the concrete in order to form a complete horizontal surface.
Further, when the base surface portion 47 is formed of metal or concrete, the base surface portion 47 and the unit units 1 are often joined with an adhesive, and when it is wood, In addition to adhesives, nailing means are also used.
On the other hand, when the two or more tunnel-type ground surface or floor heating devices 1 are arranged two-dimensionally adjacent to each other as will be described later, in addition to the joining means, the tunnel-type ground surface An appropriate number of appropriate coupling fixing members 43 whose side cross-sectional shape is L-shaped, for example, are provided on the peripheral edge of the lower surface of the surface or floor heating device 1, and appropriate bolts and nuts are provided via the coupling fixing members 43. The base surface portion 47 can be fixed using a screw or a known coupling technique.

In particular, the coupling fixing member 43 is provided along the lower end portion of the side wall surface portion 3 formed in parallel to the central axis of the space region 10 in the tunnel-type ground surface or floor heating device 1. The reason is that, as will be described later, when arranging a plurality of the tunnel-type ground surface or floor surface heating devices 1 adjacent to each other, the space region 10 is adjacently arranged in the central axis direction. Is arranged continuously in the direction in which the central axes of the space region 10 coincide with each other, and it is desirable to employ means for directly joining and fixing the respective joining surfaces without leaving a gap. On the other hand, in the direction orthogonal thereto, there is no technical problem even if a space is provided, and the fixing work is easy because there is a side wall surface portion 3 in each tunnel type ground surface or floor surface heating device 1. Workable That.
In addition, the arrangement | positioning site | part of the said connection fixing member 43 of the said tunnel type ground surface or floor surface heating apparatus 1 is between the said adjacent tunnel type ground surface or floor surface heating apparatuses 1 as shown in FIG. 3 (A). It is a specific example that is desirably provided in a shifted manner.

Next, another specific configuration example of the tunnel type ground surface or floor surface heating device 1 according to the present invention will be described in detail with reference to FIG.
That is, FIG. 5 shows the configuration of the third specific example according to the first aspect of the present invention described with reference to FIG. 1C, and the substrate portion 2 having a thickness of 3 mm. On the base plate part 2, the heat generating covering part 5 formed in a concave shape composed of the side wall surface part 3 having a height of 12 mm and the ceiling part 4 having the peripheral part thereof is formed on the substrate part 2. It arrange | positions on the said board | substrate part 2 so that the closed space part 6 may be formed.

Further, in the specific example, the inside of the heat generating covering 5 is inside the heat generating covering 5 as shown in the internal cross-sectional views shown in FIGS. In parallel with one longitudinal direction of the substrate part 2, at least two shielding wall parts 81 and 82 are arranged adjacent to each other while maintaining a parallel state with a desired interval therebetween. Three sets 85 (85-1, 85-2, 85-3) are arranged in parallel with each other at a desired interval, and directly with the one shielding wall portion set 85-1. One side wall surface portion 3 "of the side wall surface portions 3 formed in parallel with the other and the side wall surface portion 3" of the pair of shielding wall portion sets 85-1 directly opposite to each other. In the 1st space area | region 9 formed between the shielding wall parts 81, heat retention property, heat storage property, or heat insulation property. A support member 11 made of an appropriate material is inserted, and between the two shielding wall portions 81 and 82 in all the shielding wall portion sets 85-1, 85-2 and 85-3. Is provided with a second space region 10 configured so that the linear or belt-like long heating element 12 can be inserted and withdrawn, and the other shielding wall portion group 85 is provided. −3 and the other side wall surface portion 3 ′ of the pair of shielding wall portion sets 85-2, which is directly opposed to and parallel to the other side wall surface portion 3 ′. A support member 11 made of an appropriate material having heat retaining properties, heat storage properties, or heat insulation properties is inserted into the third space region 13 formed between the shielding wall portion 82 and the shielding wall portion 82 directly facing the surface. Between all the shielding wall part sets 85-1, 85-2, 85-3 The made are fourth space area 14 has a support member 11 made of a suitable material having a thermal insulation or a heat storage or heat insulation has a configuration that is inserted.

The width of the second space region 10 in the specific example is set to 20 mm, as in the specific example described above, and the length in the longitudinal direction of the tunnel-type ground surface or floor heating device 1; That is, the length of the second space region 10 in the direction parallel to the central axis direction is set to 1800 mm, while the length (width) in the direction orthogonal to the second space region 10 is set to 900 mm.
And in this specific example, the said 1st 2nd space area | region 10-1 is the said tunnel type ground surface or the center part in the width direction of the said tunnel type ground surface or the floor surface heating apparatus 1. One and the second space region 10-2 are arranged in parallel to the longitudinal axis of the floor heating device 1 and at the same time, at the site 300 mm away from each other in the left and right directions around the center. 10-3 is respectively arranged in parallel with the first second space region 10-1.

In the specific example, the linear or belt-like long heating element 12 is not yet inserted in each of the three second space regions 10-1 to 10-3. In the individual fourth space regions 14 formed between the three second space regions 10-1 to 10-3, and maintained in the hollow body, and the first The first space region 9 formed between the second space region 10-1 and one side wall surface portion 3 'of the tunnel-type ground surface or floor heating device 1, and the third space region 10'. In the third space region 13 formed between the second space region 10-3 and the other side wall surface portion 3 '' of the tunnel-type ground surface or floor heating device 1, The desired support member 11 has already been inserted.

Further, the method of forming the second space region 10 in this specific example is formed by the same method as that described in FIG. 4, and in particular, the pair of opposed collar portions X <b> 1. And the end portion of X2 are not welded continuously in the direction of the central axis of the second space region 10, but are indicated by the circles (Y1, Y2) in FIG. , Y3...), The second space region 10 is formed by performing a spot welding process discontinuously at a desired interval.
Of course, in the present specific example, when the second space region 10 is formed, the joint portion between the tip portions of the pair of opposed flange portions X1 and X2 is the central axis of the second space region 10. Needless to say, a method of continuous welding in the direction can also be adopted.
In the present invention, unit parts of the tunnel-type ground surface or floor heating device 1 having such a structure are manufactured in advance by producing a plurality of types of units formed by appropriately changing the length and width. In addition, in order to heat a desired area portion, it is possible to cope with it by two-dimensionally adjoining each other by appropriately combining the plurality of types of unit parts.

Here, FIG. 9 shows a configuration example of the unit structure of the tunnel type ground surface or floor surface heating device 1 used in the present invention.
That is, in the present invention, for example, each frame size is typically a pattern of 1800 × 900 mm, 900 × 900 mm, 1800 × 450 mm, 300 × 450 mm, 1800 × 300 mm, or the like.
Of course, in the present invention, it is needless to say that a unit having a longer length or width can be created.
In each drawing in FIG. 9, the alternate long and short dash line portion indicates a portion in which the second space region 10 is formed, and a portion in between is a space region in which the support member 11 is inserted. 9 is shown.

Next, in the present invention, a predetermined linear or belt-like long heating element 12 is inserted into the tunnel-type ground surface or floor heating device 1 and the second space region 10, and the linear Alternatively, the tunnel-type ground surface or the entire floor surface heating device 1 is heated and heated by appropriately applying an energization treatment to the belt-like long heating element 12.
In the present invention, a configuration that is fundamentally different from the configuration in which the linear or belt-like long heating element 12 is used in a conventional similar floor heating apparatus is employed. The linear or belt-like long heating element 12 is always used in a linear form, and the operator uses any equipment for the linear or belt-like long heating element 12. In addition, the linear or belt-like long heating element 12 that can be manually inserted into the second space region 10 and is defective or malfunctioning, or the line that cannot perform the heating operation. The strip-like or belt-like long heating element 12 can be used by itself from the second space region 10 manually without using any equipment. It is possible to take out from two space areas 10 One in which was constructed as that.

By adopting such a configuration, in the conventional technology, even if one linear or belt-like long heating element 12 fails and becomes inoperable, the entire floor heating device However, in the present invention, the tunnel-type ground surface or floor heating device 1 itself can be used as it is, and the linear or belt-like length which has become a problem is not affected. By exchanging only the scale-like heating element 12, it is possible to exhibit an excellent effect that the repair is completed.
Here, if the linear or belt-like elongated heating element 12 used in the present invention is described, the configuration of the elongated heating element portion 12 used in the present invention is particularly limited. Although not shown, for example, as shown in FIG. 7, a heating layer 53 in which carbon particles and appropriate synthetic resin adhesive particles are mixed is disposed between a pair of electrodes 51 and 52. A heating element 3 having a structure covered with an appropriate insulating synthetic resin material layer 54 and configured such that when the electrodes 51 and 52 are connected to a predetermined power source and energized, the heating layer 53 generates heat is used. Is desirable.

When the synthetic resin particles are designed so that the volume thereof changes according to the temperature, the heating element 12 described above changes the amount of electricity applied to the heat generating layer 53, so that a wire having a so-called self-temperature control function. It is known as a strip-like or belt-like long heating element 12 (PTC heating wire), and it is desirable to use the long heating element 12 having such a configuration.
However, as described above, the long heating element 12 in the present invention particularly needs to use a linear or belt-like long heating element, and the shape thereof also has a circular cross section. It may be of a linear body structure or may be a belt-like heating element having a flat cross section.
Furthermore, the elongated heating element 12 used in the present invention is for adjusting the heating temperature as compared with the case of using a linear heating element using conventional electric energy, for example, nichrome wire. In addition, since it is not necessary to use an extra control circuit component such as a thermostat means, the structure of cost reduction can be simplified.
However, the linear or belt-like long heating element 12 used in the present invention sufficiently generates heat even at a low temperature, and the heating element has self-temperature controllability, so that temperature control such as a thermistor is performed. It has the feature that no device is required.

  On the other hand, in the present invention, the long heating element 12 needs to be set to be longer than at least the second space region 10 described above. When the heating element portion 12 is inserted and arranged in the second space region 10, a part of one end thereof is arranged to protrude outward from the open end portion 123 of the second space region 10. Therefore, it becomes convenient when the end of the elongated heating element 12 is electrically joined to appropriate power supply means 7 described later.

In the present invention, the second space region 10 is formed as a tunnel-like structure having a hollow linear tube structure, and the long heating element 12 is configured to be freely inserted and extracted. In consideration of the fact that the lifetime of the elongated heating element 12 is around 5 years, if at least one of the elongated heating element 12 in use deteriorates its heating characteristics, Only the long heating element 12 having a deteriorated heat generation characteristic is extracted from the second space region 10 and removed. Instead, the new second heating element 12 is empty. Since it can be easily inserted into the space region 10, the entire tunnel type ground surface or floor surface heating device 1 according to the present invention is discarded and replaced with the new tunnel type ground surface or floor surface heating device 1 in its entirety. Wasteful and costly maintenance tube It becomes that way is a big cost advantage to say that it is not necessary to the adoption obtained.

In the conventional technology, basically, the long heating element 12 is layered in a zigzag manner in order to reduce the cost and maintain the heat generation effect as high as possible inside the heat storage concrete substrate. Since it is bent and inserted, it is impossible to freely remove only the elongated heating element portion 12 from the concrete substrate portion, and accordingly, a plurality of the elongated heating element portions 12 in use can be removed. Of these, if even one of the heat generation effects deteriorates, the thermal storage concrete board itself must be replaced with a new thermal storage concrete board itself, so the running cost including repair costs has increased significantly. On the other hand, according to the present invention, it is possible to achieve a remarkable effect that such a problem can be repaired and repaired efficiently and inexpensively with an extremely easy configuration.
In the present invention, the heat generation characteristic value of the elongated heating element portion 12 is measured at an appropriate time interval, and the replacement timing of the elongated heating element portion 12 is found at an early stage so that the failure is detected. It is desirable to perform repairs and repairs as soon as possible before they are revealed.

In the present invention, for this purpose, the current flowing in the elongated heating element portion 12 or the appropriate portion, preferably, the connecting portion between the elongated heating element portion 12 and the power supply means 7 or A voltage or a resistance value of the elongated heating element 12 is measured at an appropriate interval, and compared with a predetermined reference value, a decrease in a desired characteristic value of the elongated heating element 12 is inspected. Things are desirable.
In the present invention, the number of the second space regions 10 used is not particularly limited, and the arrangement interval between the second space regions 10 is not particularly limited. It can be determined as appropriate in consideration of the place of use, heat storage and insulation conditions, and the like.
Further, in the present invention, it is not necessary to insert the elongated heating element portion 12 in all of the second space region 10 arranged in the tunnel type ground surface or the floor heating device 1. For example, among the plurality of second space regions 10 arranged in parallel, every other linear or belt-like long heating element 12 is inserted, and the second space therebetween is inserted. It is possible to configure the region 10 so that the elongated heating element 12 is not inserted, and the method is appropriately determined in consideration of the purpose and place of use of the present invention, heat storage and heat insulation conditions, and the like. I can do it.

In the present invention, one long heating element 12 is basically inserted into the one second space region 10, but depending on the case, the one It is also possible to insert two or more of the elongated heating element portions 12 into the second space region 10 of the book.
In the present invention, the linear or belt-like elongated heating element 12 has appropriate rigidity and appropriate flexibility, and therefore one open end 123 of the second space region 10. Therefore, it is possible to insert and remove the long heating element 12 easily, quickly and efficiently manually, so that an operator can use it without having to use specific equipment separately at the site. Since the operation of inserting or removing the elongated heating element 12 into or from the second space region 10 can be executed manually and in a short time, the tunnel-type ground surface or floor heating is still possible. Since the device 1 itself can be used as it is without being destroyed or replaced, it is possible to significantly reduce the cost related to maintenance including the construction cost.

In the tunnel-type ground surface or floor surface heating device 1 or the large surface heating device 100 according to the present invention, the linear or belt-like long heating element is formed in the second space region 10. 12, the end of the second space region 10 opposite to the end where the linear or belt-like long heating element 12 is inserted is made of metal as shown in FIG. Alternatively, it is desirable to insert and close the lid member 102 having an appropriate shape made of synthetic resin or rubber resin.
That is, in the tunnel-type ground surface or floor surface heating device 1 according to the present invention, each of the second space regions 10 has a main portion 21 formed in a straight line, and one end portion thereof. 23 is one end edge portion 123 of the tunnel-type ground surface or floor surface heating device 1, the side wall surface 3 of the tunnel-type ground surface or floor surface heating device 1 or the upper surface thereof, that is, a part of the ceiling portion 4. It is one of the specific examples that it is desirable to have a structure projecting outward from the outside toward the upper side.
Furthermore, in the present invention, when the elongated heating element portion 12 disposed in the second space region 10 detects a heat generation characteristic value lower than a preset heat generation characteristic value. In this case, it is also desirable that the configuration is such that it can be replaced with the new long heating element 12 individually at that time.

  The construction method of the tunnel-type ground surface or floor surface heating device 1 in the present invention is not particularly limited, but for example, a desired number of the plurality of second space regions 10 described above, A tunnel-type ground surface or floor heating device 1 arranged and formed in the heat generating covering portion 5 by a method illustrated in FIG. 1 to FIG. 3 at a desired interval is manufactured in a predetermined factory, and a predetermined number, After being transported to the construction site and arranged and fixed at a desired site in accordance with a desired design, the desired interior of each second space region 10 of the respective tunnel type ground surface or floor heating device 1 is desired. The long heating element 12 is manually inserted by an operator, and then the individual long length inserted into the second space region 10 of the tunnel-type ground surface or floor heating device 1. Arranged at the end of the heating element 12 Each of the electrodes 51 and 52 is connected to a power source means 7 provided on or near the tunnel-type ground surface or the surface of the floor surface heating device 1 and an appropriate connector means 78 by an operator's manual work. The operation is completed through the connection operation.

The power supply means 7 according to the present invention is provided in the vicinity of an appropriate edge portion of the tunnel type ground surface or floor surface heating device 1, and the side wall surface 3 of the tunnel type ground surface or floor surface heating device 1 or its ceiling part. 4 may be arranged by being directly joined to a part of 4 or may be arranged and formed in a non-contact manner with respect to the side wall surface 3 or the ceiling portion 4 thereof.
As the configuration of the power supply means 7 in the present invention, for example, as shown in FIG. 8, a DC power supply 71 connected to an appropriate external power supply, and a positive electrode line portion extended from the DC power supply 71. 72, a negative electrode line part 73, and a plurality of switching parts including a branch part for supplying electric power from each of the electrode line parts to the individual electrode lines 51 and 52 in the plurality of elongated heating element parts 12. 77, and the positive electrode line part 72 and the negative electrode line part 73 connected to the switching part 77 are configured to be detachably connectable to individually connect the electrode lines 51 and 52. In order to individually control the ON / OFF operation of the appropriate switching unit 78 and the individual switching unit 77, a control circuit unit 74 individually connected to the individual switching unit 77, and the control circuit unit Thailand connected to 74 It is desirable specific example over means 75 and the control program for controlling the operation of the control circuit unit 74 and a storage unit 76. which is built.

As an example of the arrangement of the power supply means 7 in the present invention, as shown in FIG. 8, it is arranged adjacent to one end edge 80 of the predetermined tunnel type ground surface or floor heating device 1. Is a preferable specific example, and in some cases, the power supply means 7 may be disposed on a part of the ceiling portion 4 of the heat generating covering 5 in the tunnel-type ground surface or floor heating device 1. Is also possible.
In any of the specific examples described above, the electrode wires 51 and 52 formed at one end of the elongated heating element 12 are manually connected by the operator via the connector means 78. In addition to being connected to the power supply means 7, the control circuit unit 74 is also connected.

By the way, the long heating element 12 used in the present invention has a characteristic of temporarily consuming a large amount of electric power when power is first supplied, and thereafter normal heat generation. While performing the operation, it has a characteristic of using a constant and small amount of power consumption.
For this reason, as in the present invention, when energization is started simultaneously to the plurality of elongated heating element portions 12 at the start of energization, the plurality of elongated heating element portions 12 are instantaneously supplied in large quantities. Therefore, there is a risk that a large voltage drop occurs, the supply of power becomes unstable, the operation of the system does not function properly, and the flickering or darkening of the lighting occurs. Therefore, as a result of intensive studies, the inventor has moved the tunnel-type ground surface or floor heating device 1 according to the present invention from the operation stop state to the next operation state. A predetermined voltage is simultaneously applied to all the long heating element portions 12 inserted in all the second space regions 10 arranged in the heat generating covering portion 5 of the floor heating device 1. Rather than first, it is preferable to select the first elongated shape inserted into the second space region 10 first (it is desirable to select the arranged portions one by one regardless of the order). After a predetermined voltage is applied only to the heating element 12, and after a period when the power consumption of the elongated heating element 12 significantly increases, the power consumption of the elongated heating element 12 is substantially reduced. While reaching a stable state, the second elongated heat generation The power supply to all the other long heating element parts 12 including the part 12 is maintained in a cut-off state, and the power consumption of the first long heating element part 12 has reached a substantially stable state. Later, power supply to the first elongate heating element 12 is maintained while power supply to all the third elongate heating elements 12 after the third is maintained in a cut-off state. In addition, predetermined power supply is started to the second elongated heating element portion 12, and then the power consumption in the second elongated heating element portion 12 reaches a substantially stable state. After that, the supply of electric power to the first and second elongated heating element portions 12 is maintained, and the supply of power to all the fourth and subsequent elongated heating element portions 12 is maintained in a cut-off state. A predetermined power supply is made to the third elongated heating element 12. A sequential energization method for controlling all the elongated heating element portions 12 used sequentially and sequentially starting voltage supply at predetermined delay time intervals by repeating the same operation thereafter. It was proved to be a specific example that it is desirable to adopt.

For example, the control circuit shown in FIG. 8 is a sequential energization method for controlling the individual long heating elements 12 so as to sequentially start voltage supply at predetermined delay time intervals. In the unit 74, the time for starting energization of the long heating element 12 is detected and determined from the time information from the timer means 75, and at the same time, a control program incorporated in the storage means 76 A specific control program configured to sequentially activate the switching unit 77 is selected from the first to nth times using a desired delay time, and the selected program is used. The individual switching units 77 up to the th are executed by sequentially switching them to the ON state at the selected predetermined delay time interval.
In the present invention, from the time when power is first supplied to one of the long heating element portions 12, the control circuit portion 74 sequentially passes the other long lengths through the desired delay time. The time interval from the start of energization to the heating element 12 to the end of the last elongate heating element 12 until the end of the last delay time is referred to as the power supply initial drive time. ing.
That is, as another specific example in the present invention, the power supply means 7 in the tunnel-type ground surface or floor heating device 1 includes one end 51 of the long heating element 12. , 52 are individually connected, and the plurality of long wires are connected during a desired initial driving time from when the desired power is first supplied to one of the long heating element portions 12. A long heating element unit sequential individual drive control means 74 that functions to connect each of the heating element units 12 to the power supply power sources 72 and 73 sequentially through a desired delay time is provided. It is a specific example that is desirable.
In the present invention, when it is not necessary to operate the tunnel-type ground surface or floor surface heating device 1 or the large surface heating device 100, it is natural that the power supply unit 71 is shut off. In the case of restarting it again, the connection control operation described above is activated again.

Below, the specific technical structure of the large-sized planar heating apparatus 100 which is the 3rd aspect which concerns on this invention is demonstrated in detail.

The center axis of the second space region 10 is arranged so as to coincide with the center axis of the second space region 10 in the other adjacent tunnel type ground surface or floor heating device 1, It is desirable to arrange so that a long second space region 10 having a series of straight lines is formed.
In the third aspect of the present invention, each of the tunnel-type ground surface or floor heating device 1 uses an appropriate coupling and fixing member 43, respectively, and uses a bolt-nut method, a screw-stop method, A fixing means such as a nailing method may be used to fix to the surface of a desired base surface 47 made of wood, plywood, various plastics, or concrete, or an adhesive or It is also possible to fix using appropriate joining and fixing means using nailing means.

On the other hand, in the third aspect, as shown in FIG. 8, the second space in the individual tunnel type ground surface or floor surface heating devices 1, 1 ′ arranged adjacent to each other. The side wall surface portions 3 and 3 ′ facing each other in the direction orthogonal to the central axis of the region 10 are formed with wall surfaces that are substantially orthogonal to the horizontal surface of the substrate portion. The central axes may be in contact with each other so that the central axes coincide with each other in a straight line shape, or, for example, a protrusion member having a desired shape or a groove portion having a concave shape at an appropriate portion thereof. It is also a preferable specific example that the above is formed and bonded and fixed so that both of them are fitted.

Further, in the present invention, a plurality of the tunnel type ground surface or floor surface heating devices 1 are configured such that each of the second space regions 10 is formed in an integrated continuous shape in the central axis direction. However, the number of the plurality of tunnel-type ground surface or floor heating devices 1 that are continuously arranged adjacent to each other in the direction is not particularly limited, The linear or belt-like long heating element 12 used in the invention is wound up on a take-up reel with a maximum length of 600 m, and is manufactured and sold.

Is possible.
In the present invention, the linear or belt-like elongated heating element 12 is further elongated by being connected to another linear or belt-like elongated heating element 12 in the middle thereof. Needless to say, it can be used.

In addition, the linear or belt-like long heating element 12 used in the present invention has appropriate hardness and moderate flexibility, so that the linear or belt-like long heating element 12 is used. 12 can be easily inserted manually from one end of the second space region 10 to the most distal end of the second space region 10 and vice versa.
That is, the linear or strip-like long heating element 12 disposed in the second space region 10 used in the present invention is a completely continuous linear or strip-like body. It is characterized by the fact that it is not bent or cut in the middle.

That is, the power consumption in the specific example according to the present invention is that the power consumption per meter of the linear or strip-like long heating element 12 is 5 W, and the linear or strip-like long length used is the same. Since the total extension distance of the scale-like heating element 12 is 32.4 m, the total power consumption of the heating element 12 is 32.4 m × 5 W = 162 W. By driving this for 10 hours per day, Power consumption is 162 W × 10 hours = 1620 W.
Therefore, the predicted power consumption for one month (30 days) is 1620 W × 30 days = 46.8 KW.
Therefore, when this is calculated as an electricity bill (1 KW = 29 yen), the expected electricity bill per month is 1496.8 yen / month.
This value is 3900 yen / month in the prior art compared with the conventional general hot water circulation heating system that heats the floor area of the same size, so the system of the present invention is quite economical. I can understand that.
