Abstract

An ultra-thin floor cooling / heating panel having a function as a floor and capable of improving floor cooling / heating efficiency is provided.
A planar upper plate 9 and a lower plate 12 having a flat fluid passage are joined together with a base 14 for introducing and discharging a fluid interposed therebetween. By providing a plurality of male screw type inlets 15a for introducing the fluid and a plurality of female screw type outlets for leading the fluid introduced into the panel, the flow rate of the fluid can be ensured and the thickness can be reduced. In addition, the inlet and outlet can be alternately connected and laid, and the pressure of the circulation pump becomes uniform, so that deformation of the panel is prevented. The lower plate 12 of the panel main body has a weir that divides the fluid passage, and the upper plate 9 and the lower plate 12 are joined by welding to form a load-bearing structure. Since the plate is placed between the laid panels to eliminate the gap and to function as a floor, the floor is not newly laid, so that the thermal conductivity can be remarkably improved.

Description

  The present invention relates to a cold / hot water floor cooling / heating panel used for a floor of a building.

  In general, there is a pipe-type floor heating apparatus that heats the antifreeze liquid and circulates the antifreeze liquid in the pipe by using the circulation pump 6. In the structure, a groove of a pipe is dug in a panel preliminarily arranged so that the pipe can be buried, and the pipe is buried along the groove and a floor is laid for finishing.

However, the above conventional floor heating apparatus has a problem that the grounding area of the floor and the piping is as small as about 1 to 2 mm, the floor thickness is thick, and a sufficient amount of heat is transmitted to the floor, so that the cooling and heating efficiency is low. For this reason, even if you wake up in the winter and start up the heating system, it takes several hours for the entire floor to warm up, and when it warms up, there is no one at home due to going to work or going to school. Some people have not put in. Also, if the power is turned off, the above problems will occur, so there is a state where the power is turned on for 24 hours. However, if sufficient heat is not transferred to the floor, it is necessary to maintain the floor heating heat continuously. There is a problem that it has to run for a long time and the amount of fuel used is too much and the heating cost is high.
At the same time, the combustion time of the boiler becomes longer, so it is a problem for CO2 emission and global warming.

In addition, when installing the above floor cooling / heating system in an existing house, there is a problem that the floor must be peeled off and the floor cooling / heating system must be laid again.

The present invention solves the problems existing in the prior art and operates the boiler by heating the floor and the panel simultaneously in about 3 to 5 minutes after the power is turned on so that the floor heating can be efficiently and reliably heated. The object of the present invention is to provide a floor heating apparatus that can reduce the amount of fuel used in an existing floor cooling and heating system to 1/10 or less because time can be reduced and CO2 emissions can be reduced.

In order to solve the above problems, the invention according to claim 1 is characterized in that the outer plate of the upper flat plate and the outer plate of the lower plate having a groove through which cold / hot water flows are joined by the seam welding 11. The gist is that the fluid passage is established.

According to the second aspect of the present invention, the lower plate having a groove through which cold / hot water flows is press-formed. In addition, weirs 13 are provided between the fluid passages to prevent panel deformation. Therefore, joining the upper and lower plates increases the strength and provides a load-bearing structure, so that even if a heavy object is placed on the top of the panel, it will not be deformed, so it is not necessary to lay a new floor on the panel. The gist is that it is a panel that has the same functions as.

The invention described in claim 3 has a function as a floor with respect to the panel structure, so that the thickness of the panel has to be suppressed and the thickness of the panel must be suppressed in order to lay a commercially available floor 12 mm at a place where floor heating / cooling is unnecessary. Then, since the pipe diameter of the pipe into which the cold / hot water is taken is small, the flow rate of the cold / hot water is limited.
The gist of the invention is that the panel is a thin panel that can secure cold / hot water from a plurality of intakes provided in the base by providing the base 14 for securing the flow rate between the upper and lower plates.

Hereinafter, an embodiment of a floor cooling and heating apparatus embodying the present invention will be described with reference to the drawings.
As shown in FIG. 6, the upper plate 9 constituting the floor cooling / heating panel 7 is formed in a flat rectangular shape in plan view, for example, by a steel plate having a thickness of 0.5 mm to 1.0 mm. Further, as shown in FIG. 6, the lower plate 12 is formed into a flat oblong shape in plan view, for example, by a steel plate having a thickness of 0.5 mm to 1.0 mm, and the upper plate 9 and the lower plate 12 are overlapped to join the two plates. 9b and 12b are joined in a state in which two flat flat pieces in a plan view are sealed with the seam welded portion 11 inside and outside.
Further, as shown in FIG. 5, the base portion 14 is sandwiched between the upper plate 9 and the lower plate 12, and the joint portions 9 a and 14 a of the upper plate 9 and the base portion 14 having a flat oblong shape in cross section are formed between the lower plate 12 and the base portion 14. The contact portions of the joint portions 12a, 14b, 12c, and 14c are joined by welding in a quadrangular annular shape in cross-sectional view.

As shown in FIG. 3, the lower plate 12 is previously drawn by a press so that the flat grooves 10 meander. Two L-shaped weirs 13 forming the meandering grooves 10 are formed, and the portions where the upper plate 9 and the lower plate 12 are in contact with each other are connected by a spot weld 17 at a plurality of locations.
