Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel constituting a bathroom of a bathroom unit, and more particularly to a heated floor panel of a bathroom which is formed so that the floor of the bathroom can be heated.

[0002]

2. Description of the Related Art Conventionally, as a floor panel of this type, for example, a pipe for passing hot water is laid in a meandering shape in a groove on the back surface, a base panel laid on the floor of an existing bathroom washing room, and this base. There is a panel formed by sandwiching a hot water flow pipe between the panels and a front panel (see, for example, JP-A-2000-121084).

[0003]

By the way, this kind of floor panel heats the hot water in a meandering manner to transfer the heat of the hot water to the washroom pan (surface panel) to heat the floor of the washroom. Therefore, it is desirable that this type of floor panel is formed so that heat of hot water can be efficiently transferred to the front panel without loss of heat energy.

However, in the conventional products, the underside of the washroom pan is open or the base panel is in contact with the floor surface of the existing bathroom washroom. Therefore, when the conventional product is used, there is a problem that the heat of the hot water is easily taken under the floor and the loss of heat energy is large.

Further, it is desirable that the washing pan (surface panel) of this kind of floor panel is formed in a thin shape so as to improve heat conduction, but since it adds weight to the bather, It must be formed in a state of high loadability and rigidity. In this case, therefore, if a large number of ribs are integrally formed and reinforced on the back side of the washbasin, the mold cost is high and the cost of the washpan is increased. Therefore, it is desirable that the panel of this type is formed so that the washing pan can be made thin and the load bearing capacity and the rigidity can be sufficiently secured at a low cost.

[0006] However, in the conventional product, it is customary to integrally form ribs on the washing pan and the load resistance and rigidity are provided by this kind of ribs. Therefore, the conventional product is expensive and inexpensive. There is a problem that this type of panel cannot be provided.

The present invention has been proposed in view of such conventional problems. Therefore, the technical problem of the present invention is to prevent the heat of the hot water from being taken under the floor in the heating floor panel of the washing place in which the hot water flow pipe is arranged in a meandering shape on the back side, and reduce the loss of thermal energy. ,
It is an object of the present invention to provide a heating floor panel for a washing room, which is formed at a low cost and has sufficient load resistance and rigidity even if the thickness of the washing pan is reduced so that heat can be transferred to the floor surface of the washing room as much as possible.

[0008]

The present invention adopts the following technical means in order to solve the above problems.

That is, according to the present invention, as shown in FIG.
A heating floor panel of a washing place in which a groove 2 having a concave curved section is formed in a meandering shape on the back side of the washing place pan 1, and a hot water flow pipe 3 is provided in the groove 2, which is the back side of the washing place pan 1. The heat insulation panel 4 is polymerized through the hot water flow pipe 3,
An elongated reinforcing member 5 is provided on the back surface of the heat insulating panel 4 (claim 1).

In this case, the inner diameter of the groove 2 is preferably selected to be the same as the outer diameter of the flow pipe 3 so that the thermal conductivity is improved. The heat insulating panel 4 is formed of, for example, foamed plastic such as Styrofoam or cork. The reinforcing member 5 is formed of an inexpensive commercial product such as hat-shaped steel, lip grooved steel, light grooved steel, and light squared steel.

According to the present invention, as shown in FIG. 6 and the like, a pipe groove 9 having a concave curved section for engaging the hot water flow pipe 3 is formed in the heat insulating panel 4 in a meandering shape. Preferably (claim 2).

This is because, in this case, the distribution pipe 3 can be assembled while the distribution pipe 3 is temporarily fixed to the heat insulating panel 4, which not only facilitates the assembling work but also improves the heat insulating property.

Further, according to the present invention, as shown in FIGS. 9 and 10, in the piping groove 9 of the heat insulating panel 4, the positions of the meandering folded-back end 9a on one side and the meandering folded-back end 9b on the other side are aligned, and It is preferable that a plurality of patterns are formed in a state in which the distance D from the meandering turn-up end 9a on one side to the meandering turn-up end 9b on the other side is different (claim 3).

According to this, even if the size of the washing pan 1 is different, by cutting the heat insulating panel 4 at the position of the cut line L, it can be shared by one heat insulating panel 4 and can be flexibly dealt with. .

Further, according to the present invention, as shown in FIG. 11, it is preferable that the washing pan 1 is formed to contain the metal particles 10 having good thermal conductivity (claim 4).

This is because, according to this, the thermal conductivity of the washing pan 1 can be improved at low cost without forming the flow pipe 3 with an expensive material having good thermal conductivity such as a copper pipe. . Examples of the metal particles 10 include particles of aluminum, copper, brass and the like.

Further, according to the present invention, as shown in FIGS. 3 and 4, a screw receiving portion 6 for screwing is formed between the adjacent grooves 2 of the washing place pan 1, and the screw receiving portion 6 is thermally insulated. The panel 4 and the reinforcing member 5 are preferably fixed together by screws 7 (claim 5).

According to this, compared with the case where the screw receiving portions 6 can be securely screwed and the entire length between the adjacent grooves 2 is formed as the screw receiving portions 6 innocently, the washing pan 1 is formed. This is because it is possible to save the material and prevent the occurrence of distortion during molding.

Further, according to the present invention, the reinforcing member 5 is formed in the meandering groove 2.
It is preferable that it is provided so as to extend in a direction orthogonal to the direction in which the traffic flows (Claim 6).

In this case, since the reinforcing member 5 is arranged so as to cross the groove 2, the load resistance becomes higher than that in the case where the reinforcing member 5 is provided along the moving direction of the groove 2, for example. This is because the strength of the washroom pan 1 can be further improved.
