Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a flooring for cooling and heating provided with a metal foil in order to improve thermal efficiency.
[0002]
[Prior art]
FIG. 4 shows a conventionally known tatami for air conditioning as a flooring for air conditioning.
In this cooling / heating tatami mat, a heat insulating plate 2 formed of foamed resin is provided on a resin-made first hollow laminated plate 1 made of a multilayer structure. A guide groove 4 for laying the pipe 3 is formed on the surface of the heat insulating plate 2.
As a method for forming the heat insulating plate 2, there are a bead foaming method and a continuous extrusion foaming method. However, in the continuous extrusion foaming method, the guide groove 4 must be formed by cutting. In that sense, it is desirable in terms of cost to form the heat insulating plate 2 by a bead foam molding method in which the guide groove 4 can be integrally formed.
[0003]
A first aluminum foil 5 is laid on the surface of the heat insulating plate 2 including the guide groove 4. Specifically, the flat first aluminum foil 5 is provided on the surface of the heat insulating material 2, and the first aluminum foil 5 is pressed along the guide groove 4 to be deformed in accordance with the shape of the guide groove 4. I have to.
[0004]
The pipe 3 is laid in the guide groove 4 on which the first aluminum foil 5 is laid. Then, in a state where the pipe 3 is laid in the guide groove 4, another second aluminum foil 6 is laid, and a resin-made second hollow laminated plate 7 is laminated on the second aluminum foil 6 as a cushioning material. ing. Therefore, the cushion property as a tatami is mainly maintained by the second hollow laminated plate 7 .
When the tatami floor a is configured in this way, a tatami surface 8 as a surface material is sewn on the tatami floor a to form a tatami mat for air conditioning. And if this tatami for air conditioning is spread in a room and it sets so that warm water or cold water may be poured through pipe 3, it can carry out floor air conditioning.
[0005]
[Problems to be solved by the invention]
However, in the conventional cooling / heating tatami mat, when a person walks on the tatami mat, unpleasant sounds such as squeaking and squeaking are generated. It has been experimentally found that this sound is generated mainly by rubbing between the first aluminum foil 5 and the surface of the heat insulating plate 2. In particular, when the heat insulating plate 2 is molded by a bead foam molding method, a relatively low foamed and hard layer called a skin layer is formed on the entire surface including the guide groove 4, so that this sound is likely to occur. .
[0006]
Further, in the conventional heating and cooling tatami mat, pressing is performed when the first aluminum foil 5 is laid in the guide groove 4. However, since the first aluminum foil 5 is not stretchable, the first aluminum foil 5 may be torn at that time, or the first aluminum foil 5 may not be cleanly deformed according to the shape of the guide groove 4. There is.
An object of the present invention is to provide a flooring for air conditioning that can be laid cleanly on the surface of a heat insulating plate including a guide groove without tearing and that does not generate unpleasant sound. .
[0007]
[Means for Solving the Problems]
The first invention is a heat insulating plate formed of foamed resin, a guide groove formed on the surface of the heat insulating plate, a metal foil laid on the surface of the heat insulating plate including the guide groove, a pipe laid in the guide groove, in cooling and heating flooring with a surface material made of directly or indirectly stacked on the insulating plate, formed into parallel streaks a plurality of protrusions with respect to the guide groove in the metal foil, these streak a convex portion is opposed to the surface of the insulating plate while parallel to the guide groove of the metal foil has a feature in that the structure laid on the surface of the insulation plate including a guide groove.
The second invention is characterized in that a resin cushion material is provided on the metal foil, and that the metal foil is provided with a streak-like convex portion opposed to the cushion material.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The embodiment shown in FIGS. 1 to 3 is for a tatami for air conditioning as in the conventional example. And the same code | symbol is attached | subjected about the same component as the tatami for heating and cooling of a prior art example, and the detailed description is abbreviate | omitted.
The greatest feature of this embodiment is that a plurality of convex portions 9 are formed on the first aluminum foil 5 as shown in FIG. Here, these convex portions 9 are made parallel to the guide grooves 4 of the first aluminum foil 5 . However, in this embodiment, a convex portion 9 that is orthogonal to the guide groove 4 is also provided.
[0009]
The first aluminum foil 5 thus formed is laid on the surface of the heat insulating plate 2 including the guide groove 4, and the convex portion 9 is opposed to the surface of the heat insulating plate 2 as shown in FIG. 2.
Then, as described in the conventional example, the first aluminum foil 5 is pressed along the guide groove 4 and deformed in accordance with the shape of the guide groove 4. At this time, the first aluminum foil 5 is deformed in accordance with the shape of the guide groove 4 while a part of the convex portion 9 is extended. Therefore, the first aluminum foil 5 can be neatly deformed in accordance with the shape of the guide groove 4 without breaking.
[0010]
When the convex portion 9 is formed on the first aluminum foil 5 as described above, the first aluminum foil 5 is kept in a state of being lifted from the surface of the heat insulating plate 2 including the guide groove 4 as shown in FIG. . Therefore, the contact area between the surface of the heat insulating plate 2 including the guide groove 4 and the first aluminum foil 5 is reduced, and even if they are rubbed, almost no sound is generated.
[0011]
Moreover, as shown in FIG. 3, the convex part 9 formed in the 1st aluminum foil 5 is gradually crushed while using it for a long time. However, no matter how long it is used, the first aluminum foil 5 does not become completely flat, and this aluminum foil 5 maintains a slightly raised state from the surface of the heat insulating plate 2 including the guide grooves 4. It will be.
Moreover, although the first aluminum foil 5 is as thin as about 100 μm, it is made of metal, and as it is used for a long time, a part of the convex portion 9 is formed on the surface of the heat insulating plate 2 formed of foamed resin by the load. I will bite in. Therefore, the first aluminum foil 5 is not easily displaced, and even if a person walks on the first aluminum foil 5, almost no sound is generated.
[0012]
In addition, when providing the resin-made 2nd hollow laminated board 7 as a cushioning material like this Example, even if it forms the convex part not only in the 1st aluminum foil 5, but in the 2nd aluminum foil 6, either. Good. And if the convex part formed in the 2nd aluminum foil 6 is made to oppose the 2nd hollow laminated board 7, it will be uncomfortable by the friction of the 2nd aluminum foil 6 and the 2nd hollow laminated board 7 on the same principle. Generation of sound can be prevented.
Alternatively, when the second aluminum foil 6 is not provided, the first aluminum foil 5 may be formed with convex portions in both directions of the surface side of the heat insulating plate 2 and the second hollow laminated plate 7.
[0013]
Et al is, although in this embodiment has been described heating and cooling mat, for example, may be of a type using a flooring material as the surface material.
[0014]
【The invention's effect】
According to the first invention, when the metal foil is pressed along the guide groove and deformed according to the shape of the guide groove, the metal foil has a guide groove while a part of the convex portion is extended. It will be deformed according to the shape. Therefore, the metal foil can be neatly deformed according to the shape of the guide groove without being broken.
And even if it uses for a long time, the unpleasant sound which a metal foil and the surface of a heat insulating material rub against does not generate | occur | produce.
According to the second invention, in the first invention, when a resin cushion material is provided on the metal foil, the cushion material and the metal foil rub against each other, and an unpleasant sound may be generated. It can also be prevented.
