Description

The present invention relates to a double floor heating device using a planar heating element and a metal floor panel made of aluminum or the like for underfloor wiring or underfloor air conditioning.
It relates to the technical field of floor heating in free access floors of office buildings and floor heating in general households.

  2. Description of the Related Art In recent years, floor heating systems that use hot water as a heat source have been widely used as double floor heating systems in office buildings, houses, etc., where pipes for circulating hot water are circulated in double floor panels.

However, the conventional double-floor panel heating system in the hot water circulation type has problems with panel members and structural problems that cannot be said to have good thermal conductivity, and it takes a long time to warm up the entire room, such as taking too much time. There were problems with efficiency, thermal efficiency, and effective utilization of heat sources.
Also, on the office OA floor, layout changes, desk movements, etc. are frequently performed, so the floor must be hard and can be moved easily.
In the hot water circulation type, there is a problem that such change and movement of wiring cannot be easily handled.
On free access floors such as OA floors, it is required that the heating means can be freely changed and not fixed.

  In addition, in floor heating using a fluid system in which hot and cold air or heat circulation pipes for circulating hot and cold water are laid evenly over the entire floor as a heat source, laying work is relatively expensive. It was not easy, and maintenance management was not easy.

As another measure, there is a method of piping the hot water pipe into the hot water mat in the double floor panel. However, even this method has a problem that it takes time until the entire room is warmed, and there is room for improvement in terms of thermal efficiency.
In addition, floor materials used in conventional floor heating, synthetic resin materials, concrete lumber, marble, etc. are said to be frequently stressed by frequent direct temperature control. .
The double floor also had room for development in terms of floor panel members.
Incidentally, there are the following prior arts in the floor heating system.
Japanese Patent Laid-Open No. 2000-283479 (name: floor heating system) Japanese Patent Laid-Open No. 10-106730 (double floor reflective floor heating device and members to be used for it)

The present invention provides an electric double-floor floor heating device that does not use a fluid heat source but can reduce costs, and enables floor heating not only for the entire floor but also for personal heating in offices and homes. The system is developed.
The challenge is to develop a floor heating system with high cost performance even compared to conventional fluid floor heating systems. Of course, even if it is installed on a free access floor, the function as the floor is not hindered.
One of the problems to be solved is that the conventional double floor uses a member with poor thermal conductivity for the double floor panel member, so it takes too much time to warm the room. Develop a double bed with good conductivity and good thermal efficiency.
As one of the problems to be solved, for example, in the office OA floor with the conventional double floor, the heating of the entire room or the entire floor is taken into consideration, so for personal heating only around one desk, etc. It was a structure that did not look upward. It is an object of the present invention to develop a floor heating system or a heating apparatus that can perform not only full floor heating but also personal heating at a partial location on the floor.

  In order to heat the floor with electric heating, heating can be done by burying a heating wire on the concrete floor itself or by laying an electric heating mat on the floor surface, but the former mainly requires prior burial from the construction stage. Because it is a fixed type, it lacks flexibility in case of retrofitting or layout change, while the latter is only placed on the floor, so it has the disadvantage that it is low in durability, such as being stepped on in an office place and disconnected. is there.

A double floor heating apparatus using a planar heating element and a metal floor panel according to the present invention is an electric heating type planar heater on a floor and has a planar heating element having a far infrared radiation heating function and the like. In addition, a metal floor panel made of aluminum or the like having a hanging edge is laid so as to cover (enclose) the planar heating element with a space of heat of heat.
The generated heat from the sheet heating element is accumulated as heat in the space covering it and transferred to the metal floor panel for floor heating. Heat can be heated evenly in the compartments where the spaces are connected.
The planar heating element has a configuration in which, for example, a belt-shaped glass fiber base fabric is impregnated with carbon and Teflon (registered trademark) and fired, electrodes are provided in parallel on both sides of the surface, and laminated with an insulating film.
The electrode is formed by printing, sticking, or sewing copper foil.
It is also possible to prepare an appropriate ceramic for the impregnated carbon so as to stably emit far-infrared rays at a low temperature.
A far-infrared PTC film can also be used for the planar heating element.
This planar heating element is placed on the floor, a space of a predetermined volume is provided around it, and a structure that stays in the internal space on the back side of the upper surface is developed to achieve efficient heating while holding the heat It is a thing.
If the sheet heating element is fixedly installed, the role of frequent opening and closing of the free access floor and the freedom of change is lost, so it is necessary to make it free.
Then, it must be protected from unexpected load applied to the planar heating element, and a partitioning screw or the like being stuck.
In the present invention, the present invention has been achieved with a configuration in which a metal floor panel also serves to protect the planar heating element based on the idea of making the planar heating element free.
In addition, there is a feature that a plurality of metal floor panels 2 are connected so as not to be in contact with each other, and are electrically insulated and arranged to form a partition area having an arbitrary shape.
The metal floor panels are positioned with synthetic resin pedestals and are arranged with fine gaps even at the top edge at positions where they do not touch each other. Since there is no conduction, the heat generated by the far-infrared radiation from the planar heating element is retained one by one so that there is no heat diffusion and no heat transfer loss.
Further, when the metal floor panel is laid near the wall surface, the metal floor panel does not come into contact with the wall surface and leaves a fine space. In other words, the metal floor panel has a leg seat or bushing at the end that comes into contact with the floor, and the metal floor panel is in contact with the opposite end or wall between the metal floor panels so that heat conduction is required. It is not installed and insulated.

Under the planar heating element, heat insulation is laid, but the heat insulation has an appropriate thickness to ensure the space behind the top surface of the metal floor panel according to the height of the metal floor panel. It is determined.
By setting the thickness of the heat insulating material, the space volume of the heat of heat can be determined.
The heat insulating material may be a heat insulating material such as a foam material or a heat insulating paint.

Further, the double floor heating device is made of a metal floor panel made of aluminum or the like which is a fixed area, for example, a heat insulating material having a size of 1 square meter, a 1 square meter planar heating element, and a 1 square meter connecting area body covering the same. You may comprise in the rectangular-shaped assembly which consists of.
Such an assembly can be pre-manufactured in a factory, and a certain area is peeled off from an arbitrary part of an existing OA floor, and the assembly is fitted into that part to perform partial heating. You can also
If an independent assembly is used, renovation and repair are easy.

The metal floor panel has a square upper surface and legs at four corners, and one or more hanging edges are formed between the opposing legs. By arranging the metal floor panels, any shape heat can be generated. A zone that forms a space can be formed.

The one or more hanging edges include a structure in which a hanging edge serving as a closing plate is provided on one of the left and right side parts, a structure provided on both sides of the left and right side parts, and a structure provided on three sides of the back part and the left and right sides.
By enclosing with the drooping edge, the heat is enclosed within a certain area.

In addition to the effect of surrounding the space, the drooping edge also serves as a leg for maintaining the metal floor panel horizontally on the floor surface, and it can also be used as a gap member at the corner of the floor is there.

  According to the double floor heating apparatus using the sheet heating element of the present invention and a metal floor panel made of aluminum or the like, first, heat conduction such as aluminum or copper having high thermal conductivity as a member of the double floor panel. By using an effective material for the floor surface, there is an advantage that the entire room can be warmed in a short time regardless of the heat source.

In addition, the metal floor panels are electrically insulated from each other and electrically insulated from the floor, and are connected to each other by a leg seat without being in contact with a minute gap and arranged in a predetermined position. Yes.
Each of the metal floor panels independently holds the heat from the planar heating element as the bulk heat and performs floor heating, so that the floor heating is free of heat transfer loss.
Since there is no uneven temperature on each part of the surface of the double floor panel, the entire temperature of each part in the room can be uniformly heated.
As described above, a metal floor panel is connected to a leg of an insulating synthetic resin pedestal. The OA floor is electrically connected from the floor (slab) to each metal floor panel. Insulated.

In addition, a planar heating element that radiates far infrared rays with electricity is laid, and the heat is blocked in the back space of a metal floor panel made of aluminum or the like and used as heating heat. And efficiently transmitted to the floor surface.
In other words, far infrared rays and electric heat are received on the back side of the metal floor panel, and hot air is retained in the interior space of the metal floor panel such as aluminum to prevent heat diffusion and efficiently heat the floor surface. This is achieved by providing at least one or more drooping edges around a metal floor panel made of aluminum or the like that can form a compartment surrounded by a certain volume by arranging the metal floor panels made of aluminum or the like. This is because of the configuration.

In addition, since it is an electric planar heating element that heats at a set temperature of 50 ° C. to 80 ° C., compared to a system that circulates high-temperature hot water or cold air in the pipe and does not overheat, Maintenance and safety are extremely high.

Under the sheet heating element, a heat insulating material is laid to reduce heat transfer loss to the floor.
In particular, when a heat insulating plate such as a foamed resin plate having a relatively shape-retaining property is used, an integrated assembly including a heat insulating material, a sheet heating element, and a metal floor panel made of aluminum or the like is obtained.
When it is an assembly, it can be sold as a single product as it is, or it can be used as a part heating reforming part of an existing OA floor.

As described above, a metal floor panel made of aluminum or the like has a square upper surface, has legs at four corners, and forms one or more hanging edges between opposing legs.
By using this hanging edge, metal floor panels made of aluminum or the like are arranged as appropriate so that a partition area of any shape can be surrounded and formed.
The partition area is the arrangement and shape of the drooping edge, such as a space with a minimum unit of a metal floor panel made of aluminum or the like, a partition area for a plurality of squares, or a partition area communicating in a ring shape, Can be designed arbitrarily.

In addition, aluminum or other metal floor panels that are slightly longer than the legs of the metal floor panel and have left and right hanging edges should be used by cutting them according to the corner edges of indoor walls and pillars. There is also an effect that can be.
In the case of aluminum metal floor panels, cutting and other processing operations are easy even at the construction site, and the height and width of the metal floor panel can be adjusted by cutting part of the metal floor panel. it can.
For example, you can cut the lower part and adjust the adjustment height with the existing floor and the surface uniform, and in addition, you can cover the unevenness of the floor with the leg seat that connects the legs, so there is no rattling and the surface finish is smooth Can be.

Here, an embodiment of a double floor heating apparatus using a planar heating element and a metal floor panel according to the present invention will be described.
This embodiment is an embodiment implemented as personal floor heating in the case of partial heating on the office OA floor (free access floor).
The heating of the entire room will not be described in detail because if the same structure as that of the personal heating is formed according to the room, the entire floor can be easily heated.
Hereinafter, an embodiment in which personal heating according to the present invention is implemented will be described with reference to the accompanying drawings.

FIG. 1 shows a first embodiment of a double floor heating apparatus using a planar heating element 1 and a metal floor panel 2.
FIG. 1 is a perspective view showing a portion of a personal floor heating type in which four metal floor panels 2 made of aluminum or the like are arranged in a row with a space 11 above the planar heating element 1. .
Under the sheet heating element 1, a substantially identical heat insulating material 3 is laid on the floor 4.
The thickness of the heat insulating material 3 is such a height that the space 11 for the bulk heat is formed so that the sheet heating element 1 does not contact the metal floor panel 2.

  In the first embodiment, an electrothermal planar heating element 1 is laid on the heat insulating material 3, and the planar heating element 1 is covered with a space 11 of the heat of heat and covered with the heat of heat without letting the heat of the heat escape. This is a structure in which a metal floor panel 2 made of aluminum or the like with legs 6 having 5 is surrounded and laid.

The planar heating element 1 is an electrothermal type, and includes a temperature adjusting device (not shown) that can change a set temperature and a lead wire with an outlet.
As shown in the cross-sectional view of FIG. 2, the sheet heating element 1 is formed by impregnating carbon and Teflon (registered trademark) into a band-shaped glass fiber base fabric and firing it to form a heating sheet, and electrodes on both sides of the surface. The copper stays are attached in parallel and laminated with an insulating film (insulating material) such as polyethylene.
Since the heat generating sheet is in the form of a sheet coated with an insulating material, it has excellent pressure resistance, and the heat generating sheet generates a large amount of 9.8 micron far infrared rays when energized from the left and right electrodes.

The metal floor panel 2 made of aluminum or the like according to the first embodiment is one having 16, 5 Cm or 33 Cm squares, and 5 Cm to 11 Cm conical column legs 6 are formed at four corners.
This dimension is only an example, and various dimensions can be adopted.
Since the ribs (standing edges) are formed in a honeycomb shape on the back surface of the metal floor panel 2 due to the demand for strength, heat conduction is good and the heat can stay well.
Further, on the left and right sides of the metal floor panel 2, a hanging edge 5 is formed as a closing plate having a slightly longer dimension than the leg 6.
The height when the leg 6 is loaded with the leg seat 9 is the same as the height of the hanging edge 5.
The leg seat 9 is made of a synthetic resin having an insulating property and a high heat insulating property, and is provided with four cylindrical portions for inserting the legs 6 at predetermined positions.
In FIG. 1, only one leg seat 9 is illustrated, but all the legs 6 are connected so as to connect the adjacent legs 6.
In the metal floor panel 2 made of aluminum or the like of the first embodiment, the drooping edges 5 are provided on the left and right sides of the panel 2 as shown in FIG. 3 showing the front and FIG. 4 showing the side.
The drooping edge 5 may be provided only on one side, or may be provided on three sides of the left and right sides and the back, or may be provided on all four sides.

Since the metal floor panel 2 made of aluminum or the like has the ribs and the drooping edges 5, a partitioned area in which hot air is retained in the internal space 11 of the metal floor panel 2 made of aluminum or the like is formed.
On the other hand, on the floor other than the partition area where the planar heating element 1 is not set, the wiring or the like is protected from heat as an OA floor.

In addition, the illustrated metal floor panel 2 made of aluminum or the like has a substantially square top surface and has legs 6 at the four corners and a hanging edge 5 formed between the legs 6. Arbitrary areas can be formed by arranging the metal floor panels 2 in an appropriate direction.
Even if it is called personal floor heating, although the area actually required, such as the size of a desk and the circumference of a desk, varies, in the present invention, an arbitrary form of partitioned area can be formed.
In the first embodiment, a plurality of metal floor panels 2 are connected so as not to come into contact with each other, and are electrically insulated and arranged to form a partition area having an arbitrary shape.
The metal floor panels 2 are positioned by synthetic resin leg seats 9 into which the legs 6 are inserted, and are arranged with fine gaps even at the upper end portions at positions that do not contact each other.
With this arrangement, there is no heat conduction or diffusion as in the case where the metal floor panel 2 is in contact with each other, so that one piece and one piece can hold the heat from the far-infrared radiation from the planar heating element. There is no heat diffusion and no heat transfer loss.
Further, the metal floor panel 2 has a fine space without contacting the wall surface even when laid near the wall surface of the room.
That is, the metal floor panel is held by the leg seat 9 or the bushing 12 having high insulation and insulating properties at the end in contact with the floor 4, and the opposite end and wall surface between the metal floor panels are fine. There is a gap, there is no contact to be conducted, and it is insulated.

In addition to the construction that can be assembled in the field, the factory also has a certain area from the beginning, for example, an assembly in which four metal floor panels 2 are arranged in series, or a heat insulating material 3 of 1 square meter and 1 square meter, for example. The sheet heating element 1 may be an assembly including a metal floor panel 2 made of aluminum or the like, which is a 1 square meter connection area body covering the planar heating element 1.
In such an assembly, it is possible to remove a certain area from an arbitrary portion of the existing OA floor 4 and fit the assembly into that portion to perform partial heating.

The metal floor panel 2 made of aluminum or the like as shown in FIGS. 3 and 4 can also be used to be placed in accordance with corner cut ends in the vicinity of indoor walls and pillars.
That is, even when the width is narrowly cut, the hanging edges 5 serving as support legs are provided on the left and right sides, so that they are independent even if they are thin, and can be stably placed at the corners.
In addition, it cannot be overemphasized that the upper surface shape of a metal floor panel 2, a magnitude | size, and a height dimension can be designed suitably.
For example, the metal floor panel 2 may be formed with the concave strip 22 in order to load a pipe or the like on the surface thereof. The presence of the recess 22 allows other additional wiring, and may be loaded with an illegal intruder sensor, a water leak sensor, or the like to exhibit other functions.

As described above, according to the present embodiment, the metal floor panel 2 itself made of aluminum or the like can be stably installed by being cut in accordance with corner cut ends of walls and pillars in the room. At the same time, since the defined area can be formed by using the drooping edge 5, efficient floor heating can be performed by the combination of the planar heating element 1 and the space 11 of the bulk heat.
In particular, since aluminum is used for the material of the metal floor panel 2, it is easy to heat the entire indoor floor in a short time as well as partial personal partial heating.

Many women in offices want to warm their feet at least because they are too cold in the summer. “Cooling the office” is serious for office workers and can be a health hazard.
The present invention fulfills this demand as an immediate response to the “cooling of the office”.
In the heating device of the present invention, an environment of partial cold foot heat is created, leading to an improvement in office efficiency.
And since it heats from the bottom, and the efficiency of heating is good by far-infrared radiation, the quick warming property of a metal, etc., there also exists an effect which becomes energy saving with little electric power consumption.

In addition, in partial floor heating such as personal heating, it is clearly shown in which part of the free access floor the floor heating is installed by using a different color metal floor panel or sticking a sticker on the panel cover. Preferably means are provided.

The embodiment 2 of the heating apparatus for the entire floor can be provided by applying the aspect of the embodiment 1 of FIG. 1 to the entire floor or arranging it in every other row.
Example 2 arranges the heating apparatus of FIG. 1 on the whole floor.
In the heating from the floor of the present invention, even if it is a full-floor heating, the temperature does not become excessive due to the nature of the planar heating element 1, and moreover, warm air accumulates on the ceiling as in the conventional case. The air conditioning temperature does not increase naturally and the energy loss is small, so the energy saving effect is high.

If the width of the sheet heating element 1 and the width of the metal floor panel 2 are not the same, and the legs of the metal floor panel 2 step on the sheet heating element 1 and pressurize, the sheet heating element 1 You may provide the hole 8 in the body 1 and the heat insulating material 3 with the same space | interval as the leg space | interval of said metal floor panels made from aluminum.
In the hole 8, a connecting leg seat 9 that supports the leg portion 6 of the metal floor panel 2 made of aluminum or the like is set, and the metal floor panel 2 is connected. The shape of the hole 8 is similar to that of the leg seat 9 and is a square hole 8 in the figure.
The hole 8 has a positioning function. If the legs 6 of the panel 2 are inserted into the leg seats 9 loaded in the holes 8 at predetermined positions, the metal floor panels 2 made of aluminum or the like are neatly arranged in order and easy to lay.
Since the formation of the holes 8 is performed by a unique technique, the electrothermal effect of the planar heating element 1 is not attenuated by the opening of the holes 8.
Arranging the planar heating element 1 with the holes 8 is not misaligned, and thus can be used for installing a heating device at a non-horizontal location such as wall heating.

In both of the above-mentioned Example 1, Example 2 and Example 3, the heat insulating material 3 and the planar heating element 1 are made into a space of a constant area with a metal floor panel without contacting with the space 11 of the bulk heat. And have the same characteristics.
The planar heating element 1 emits far-infrared rays and transfers the heat of heat, so that the temperature on the partitioned surface is uneven without applying stress to the metal floor panel 2 by a direct temperature change. Because of this, combined with the good thermal efficiency of aluminum, the unique effect of being able to warm evenly in a short time is exhibited.

(1) It can be used as a safe floor heating system without water leakage or leakage in offices or general houses.
(2) Since the heat efficiency is good and partial heating is possible, the air-conditioning temperature of the entire room naturally decreases and contributes to energy saving.
(3) It can be used for partial floor heating reforming of existing OA floors.
(4) Since the floor heating itself is not fixed, it can cope with frequent relocation and change of the free access floor.
(5) In addition to floor heating, this device can be set on a wall surface heating or a partition around a desk to develop partition heating.

In addition, it is possible to divide the area into cold and warm areas in offices and stores by laying patterns of planar heating elements, and depending on the work contents, it can also be applied to improve work efficiency by setting a cold and warm environment. .
It is a floor heating device especially suitable for free access floors.
