Description

[0001]
[Industrial applications]
The present invention relates to an apparatus for laying a hot water mat on which a heat radiating pipe is laid on a floor of a room and circulating hot water generated by a heat source device in the heat radiating pipe to perform floor heating.
[0002]
[Prior art]
A conventional floor heating device will be described with reference to FIG. In FIG. 4, 1 is a hot water mat made of one sheet of foamed polyethylene, 2 is a small joist alternately inserted at a fixed interval, and 3 and 3a are loops between the small joists 2 in the hot water mat 1 in a one-way manner. Hot water flows into the heat radiating pipes 3 and 3a from the two hot water outlets on the left side of the hot water header 4 attached to the middle of the hot water mat 1 into the heat radiating pipes 3 and 3a. The hot water flows around the inside of the mat 1 while making a U-turn at the tip of the small joist 2 and finally reaching the two return ports on the right side of the hot water header 4.
[0003]
[Problems to be solved by the invention]
Therefore, in the case of the conventional hot water heating apparatus, there is a problem that the heat radiation temperature is high on the left side and low on the right side with respect to the hot water header 4.
[0004]
[Means for Solving the Problems]
An object of the present invention is to provide comfortable floor heating by averaging the heat radiation temperature from the entire surface of the hot water mat, and its configuration is as follows.
In a floor heating device in which small joists are alternately inserted into a flat square mat body and two sets of heat radiating pipes are arranged in a loop between the small joists, the small joist located at the extreme end. A hot water header is located near the hot water header, and a radiating pipe is densely piped close to the innermost joist, and hot water flows toward the side far from the hot water header. A floor heating device that is set to return via a portion located outside the joist.
[0005]
[Action]
Approximately 60 ° C hot water supplied from the heat source unit enters the header from the hot water inlet of the hot water header, splits into two insides, enters the two radiating pipes from the hot water outlet, and goes farther to the hot water header. Make a circuit and return to the hot water header via the hot water mat outside the small joist near the hot water header. At this time, because the space between the radiating pipes near the small joist where the coldest hot water circulates is close, and because the heat radiating pipe through which high-temperature water passes is close to this small joist, The amount of heat radiation is equal to the others.

【Example】
FIG. 1 is a plan view of a floor heating device according to the present invention, FIG. 2 is a cross-sectional view taken along the line AA ′, 1 is a hot water mat, 2 is a small joist, 3, 3a is a radiating pipe, and 4 is a small end. This is a warm water header provided near the joist 2a. FIG. 3 shows the structure of the hot water header 4. The hot water header 4 is provided with a hot water inlet 5 and a hot water outlet 6 connected to a heat source device on the outside, and provided with hot water outlets 7, 7a on the right inside. The hot water return ports 8 and 8a are provided on the left side, respectively, the hot water inlet 5 and the hot water outlets 7 and 7a are connected by a bifurcated hot water branch flow path 9, and the hot water return ports 8 and 8a and the hot water outlet 6 merge. The heat radiation pipes 3 and 3a are connected to the hot water outlets 7 and 7a, and the outlets are connected to the return ports 8 and 8a. Further, the heat radiating pipes 3 and 3a of the hot water mat close to the small joist 2a are piped close to the small joist 2a (at a close pitch).
[0007]
According to the above embodiment, the hot water supplied from the heat source device to the hot water inlet 5 of the hot water header 4 is divided into two flows by the internal hot water branch flow path 9 and the radiating pipe 3, from the hot water outlet 7, 7a. 3a, makes a round from the inside of the hot water mat 1 farthest from the hot water header 4, passes through the inside of the hot water mat 1 outside the small joist 2a, and reaches the hot water outlet 6 from the hot water merging flow path 10; To return to the heat source unit. In FIG. 1, arrows indicate the flow direction of the hot water in the heat radiation pipes 3, 3a.
[0008]
【The invention's effect】
As described above, the present invention provides a hot water header at a position close to the small joist at the end of the hot water mat, and shifts the interval between the heat radiation pipes located inside the small joist at this end toward the small joist at the end to pitch. Are set densely, so that the amount of heat radiation per area can be made equal to the others on the end side where the hot water temperature is the lowest and the amount of heat radiation is small. As a result, it is possible to solve the problem that the temperature on one side is high and the temperature on the other side is low with respect to the hot water header. Therefore, comfortable floor heating becomes possible.
