DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a top view of a floor warm mat. The floor warming mat 2 according to the present invention is a single sheet composed of a plurality of basic mats 10 connected by a connecting portion 11 to form a single unit, in which a refrigerant pipe 20 is provided. In addition, the connecting part 11
For example, a hinge structure is possible.

The basic mat 10 is formed of a flexible material into a rectangular shape, and its long side is the same length as the floor warming mat 2, and the long side is connected to each other by a connecting portion 11.

The refrigerant pipe 20 is made of a flexible material such as a copper pipe or a stainless steel pipe, and is a thin pipe having an inner diameter of about 6.35 mm or less.

In FIG. 1, a refrigerant pipe 20 is indicated by a dotted line, and an inlet / outlet 21 for a refrigerant connected to a refrigeration cycle, a fixing part 22 fixed to the basic mat 10, and a basic mat 1
The entrance 21 is cross hatched, and the bend 23 is obliquely hatched, so that these areas can be identified.

The inlet / outlet section 21 is provided so that the refrigerant pipe 20 is below the floor.
Approximately 30c to be connected to refrigerant piping from a compressor etc.
m is not fixed but movable.

This prevents an excessive force from acting on the refrigerant pipe 20 during the pipe connection construction, thereby facilitating the construction work and preventing the refrigerant pipe 20 from being damaged.

The fixing portion 22 is fixed to the basic mat 10 so as to prevent the refrigerant pipe 20 from shifting due to movement of a person or the like.

The bent portion 23 is provided on the basic mat 10 in a semi-fixed or non-fixed state, and continues to the adjacent basic mat 10 in a large curve. This is for the following reason.

That is, when the floor warm mat 2 according to the present invention is transported or the like, it is transported in the form of a jutan. At this time,
The floor warm mat 2 bends mainly at the connecting portion 11.

However, all the refrigerant pipes 20 are
0, the refrigerant pipe 20
Concentrated load is applied to the wire, which may cause damage such as cracks.

Therefore, the bent portion 23 corresponding to the connecting portion 11
Is unfixed or semi-fixed so that when the floor warming mat 2 is wound in a jutan, the bent portion 23 is elastically deformed so that the weight distribution is performed.

As a matter of course, since the refrigerant pipe 20 is formed of a flexible member as described above, it can be elastically deformed to some extent. Is small, so the size (winding diameter) when the jutan is wound becomes large. However, by providing the bent portion 23, it is possible to reduce the winding diameter.

In order to prevent damage to such a dew winding, measures such as increasing the thickness of the refrigerant pipe 20 can be considered. However, in this case, the refrigerant pipe 20 becomes thicker. (When the inner diameter is fixed), there is a disadvantage that the amount of the refrigerant that can flow is reduced (when the outer diameter is fixed). However, in the configuration according to the present invention, it is not necessary to increase the thickness of the refrigerant pipe 20 more than necessary, so the above-described inconvenience does not occur.

As described above, even if the floor warming mat 2 is wound with a jutan, the refrigerant pipe 20 is not damaged, and there is no possibility of refrigerant leakage or the like.

The arrangement of the refrigerant pipe 20 is not limited to the arrangement shown in FIG. 1, but may be as shown in FIGS. The arrangement configuration of the refrigerant pipe 20 shown in FIG. 2 is a case where the fixing portion 22 is provided in a diagonal direction of the rectangular basic mat 10.

The piping configuration shown in FIG. 3 is a case where the outward path and the return path meander, and an entrance 21 is provided in the same basic mat 10.

The piping configuration shown in FIG. 4 is a case in which the doorway 21 is provided in the uppermost lowermost basic mat 10 by meandering from the upper stage to the lower stage in FIG.

In the piping configuration shown in FIG. 5, the refrigerant flowing from the uppermost basic mat 10 in FIG. 5 is divided into a plurality of refrigerant pipes 20 and meandered, then joined at the lowermost stage and meandered again. This is the case where it leads to the top row.

In any of these configurations, the entrance 2
1, the bent portion 23 and the fixed portion 22 are provided, and the operation and effect thereof are as described above.

Next, a description will be given of a case where the floor warming mat 2 having the above configuration is transported, constructed, and heated. When conveying the floor warm mat 2, the floor warm mat 2 is wound in a jutan. At this time, as described above, since the load caused by the bent portion 23 being wound in a jutan is dispersed and absorbed, the winding can be made small and the refrigerant pipe 20 can be prevented from being damaged.

Then, the floor warm mat 2 is spread indoors, and a refrigerant pipe from a compressor or the like piped under the floor is connected to the entrance 21 of the floor warm mat 2. At this time, the entrance 2
1 needs to be bent under the floor, but the refrigerant pipe 20
Since it is made of a flexible member and the entrance 21 is not fixed, the bending is easy and the refrigerant pipe 20 can be prevented from being damaged by the bending.

The floor heating mat 2 is constructed in this manner,
A refrigerant circulation circuit as shown in FIG. 6 is formed. In the figure, reference numeral 30 indicates an outdoor unit, and reference numeral 40 indicates an indoor unit.

The outdoor unit 30 comprises a compressor 31, a four-way valve 32 for changing the circulation direction of the refrigerant, a decompressor 33 for reducing or reducing the refrigerant, and an outdoor heat exchanger 3 for exchanging heat between the refrigerant and the outside air.
4 and so on.

The indoor unit 40 opens and closes the floor heating mat 2, an indoor heat exchanger 42 for exchanging heat between the refrigerant and the indoor air during cooling, and a refrigerant pipe connected to the floor heating mat 2 to heat the room. It has a valve 41 and the like for supplying the refrigerant to the floor warm mat 2.

During floor heating, the four-way valve 32 is switched so that the refrigerant flows in the direction of the solid line arrow.
Open 1. As a result, the refrigerant gas that has been compressed by the compressor 31 and has become high temperature is supplied to the floor warm mat 2.

The refrigerant supplied to the floor warming mat 2 flows through the refrigerant pipe 20 and exchanges heat with an object placed on the floor warming mat 2 such as room air or a human body, and loses heat. After condensing, the pressure is reduced by the decompressor 33 and returns to the compressor 31.

On the other hand, when cooling the room, the four-way valve 3
2 is switched so that the refrigerant flows in the direction of the dotted line arrow, and the valve 41 is closed so that the refrigerant is supplied to the indoor heat exchanger 42.

Thus, the refrigerant from the compressor 31 is sequentially supplied to the outdoor heat exchanger 34 and the decompressor 33, and is supplied to the indoor heat exchanger 42 as liquefied refrigerant.

The refrigerant evaporates in the indoor heat exchanger 42 to cool the indoor air, and returns to the compressor 31 to complete the cycle.

[0040]

As described above, according to the first aspect of the present invention, a plurality of basic mats are foldably connected by the connecting portion, and the refrigerant pipe near the connecting portion is movably provided. Therefore, the load when the floor warming mat is wound with jutan can be dispersed and absorbed at the semi-fixed or non-fixed portion, and it is possible to prevent the refrigerant pipe from being damaged.

According to the second aspect of the present invention, since the refrigerant pipe is formed by the flexible member, the pipe can be easily constructed, and is prevented from being damaged by being elastically deformed when it is wound with jutan. Becomes possible.

According to the third aspect of the present invention, since the refrigerant inlet / outlet portion of the refrigerant pipe is not fixed, it is easy to perform a bending process or the like in the construction, and the refrigerant pipe is not damaged by the processing. It becomes possible.
