There are complications such as the need for regular cleaning for hygiene reasons. In addition, since it uses only one type of electric heater, the usage cost is not low.

Unit baths with electric heaters embedded in the floor of the washing area are also known, but like the mats mentioned above, it is not recommended to use the heaters near water, and they also have the disadvantage of being high in both manufacturing and usage costs. be.

In view of these conventional problems, the present invention provides a bathroom floor heating structure that is free from the dangers of electric heaters, has low manufacturing and usage costs, and is capable of heating the washing area floor to an appropriate temperature. That is.

[Means to solve the problem]

To this end, the present invention utilizes a heat pipe to transmit the heat of hot water in a bathtub to the floor of a washing area to heat the floor, and its configuration is as follows.

(1) A heat pipe is embedded in the floor of the bathroom washing area, and a pocket filled with a solid or liquid heat medium is provided on the side or bottom of the bathtub, and the heat collecting part of the heat pipe is connected to the A bathroom floor heating structure connected to the pocket part so as to be in direct contact with a heat medium.

(2) A heat pipe is embedded in the floor of the bathroom washing area, and a pocket part on the side or bottom of the bathtub is filled with a solid or liquid heat medium and in which a heat pipe for heating the heat medium is arranged. The heat collecting part of the heat pipe for heating the heat medium was connected to the bathtub, and the heat collecting part of the heat pipe embedded inside the floor was connected to the pocket part so as to be in direct contact with the heat medium. Heating structure for the bathroom floor.

(3) A heat pipe is embedded in the floor of the bathroom washing area, and a pocket part on the side or bottom of the bathtub is filled with a solid or liquid heat medium and in which a heat pipe for heating the heat medium is arranged. A heat exchange chamber is provided in the middle of the hot water pipe from the reheating boiler, and the heat collection part of the heat pipe for heating the heat medium is connected to the chamber, and the heat exchanger that is embedded inside the floor is A bathroom floor heating structure in which a heat collecting part of a pipe is connected to the pocket part so as to be in direct contact with the heat medium.

(4) A heat pipe is embedded in the floor of the bathroom washing area, and the side or bottom of the bathtub is equipped with a heating mechanism that uses water other than hot water from the bathtub as a heat source, and is filled with a solid or liquid heat medium. A bathroom floor heating structure in which a heat collecting part of the heat pipe embedded in the floor is connected to the pocket part so as to be in direct contact with the heat medium.

When attempting to collect heat from hot water in a bathtub using a heat pipe, the heat collecting part of the heat pipe cannot be installed in such a way that it protrudes into the bathtub, and even if special structural measures are taken, the heat collecting part It is not easy to bring the water into direct contact with hot water with a sufficient contact area. In view of these problems, the present invention collects heat using a heat pipe via a heat medium in a pocket attached to the bathtub.
With this kind of structure, there is no problem even if the heat collecting part of the heat pipe is directly inserted into the heat medium in the pocket part, and the entire circumference of the heat collecting part is brought into contact with the heat medium to ensure sufficient contact with the heat medium. The area can be secured.

In order to increase the heating efficiency of the floor, the flooring of the washing area is made of synthetic resin boards mixed with one or more types of metal, ceramic, or other inorganic powders that have higher thermal conductivity than the resin. It is preferable to configure.

Further, in order to prevent damage to the flooring and wall materials due to expansion of the heat pipe, it is preferable to cover the end of the heat pipe on the washing area floor side with an elastic coating material.

[Effect]

According to the configuration (1) above, the heat medium in the pocket part is
It is heated by the hot water inside the bathtub via the bathtub wall.

The heat collecting part (evaporating part) of the heat pipe located inside the pocket part collects heat from the heat medium and transmits this heat to the heat radiating part (condensing part) embedded inside the washing area floor part. The floor is heated by the heat radiated from the heat radiating section.

Furthermore, according to the configurations (2) and (3) above, the heat medium in the pocket is not only heated by the hot water in the bathtub through the bathtub wall, but also by the heat pipe for heating the heat medium in the pocket. heated. That is, in the configuration (2) above, the heat collecting part of the heat pipe for heating the heat medium collects heat from the hot water in the bathtub, transmits this heat to the heat radiating part in the pocket part,
Heat the heat medium. In addition, in the configuration (3) above, the heat collecting part of the heat pipe for heating the heat medium collects heat from the hot water passing through the chamber in the middle of the hot water supply pipe, transfers this heat to the heat radiating part in the pocket part, and heats the heat medium. do. In either case, the heat collecting part (evaporating part) of the heat pipe located inside the pocket collects the heat of the heat medium, and transfers it to the heat dissipating part (condensing part) embedded inside the washing area floor. tell.

In particular, in the configuration (3) above, the heat collection part of the heat pipe for heating the heat medium collects heat not from the hot water in the bathtub but from the hot water in the hot water supply pipe, so the heat collection temperature by the heat pipe is high. This method has the advantage that when reheating is stopped, it becomes difficult for the heat collecting section to collect heat, so compared to case (2) above, where heat is collected from the hot water in the bathtub, the temperature of the hot water in the bathtub decreases less. There is also.

Furthermore, according to configuration (4) above, the heat medium in the pocket is heated by the hot water in the bathtub via the bathtub wall, and is also heated by the heating mechanism disposed in the pocket. The heat collecting section (evaporating section) of the heat pipe located within the pocket section collects the heat of the heat medium and transmits it to the heat dissipating section (condensing section) embedded inside the washing area floor section. Further, according to this configuration, the heat of the heat medium heated by the heating mechanism in the pocket section is also transmitted to the hot water in the bathtub via the bathtub wall, which is useful for keeping the hot water in the bathtub warm.

The floor of the bathroom washing area only needs to be heated to a level that does not make you feel cold when you step into the bathroom, and according to the present invention, the heat pipe can heat the floor to at least that level. The floor can be heated. In particular, the water in the bathtub is usually heated on a hot day, and the bathtub is often not bathed immediately after it is boiled, so the floor is appropriately heated by the action of the heat pipe before bathing.

In particular, when the material of the bathtub is FRP material with relatively high heat insulation properties, the configurations (2) to (4) above, in which a heat pipe or other heating mechanism for heating the heat medium is provided in the pocket part, may be used. According to the method, the heat medium in the pocket part is effectively heated,
The floor can be heated efficiently using the heat pipe.

When the flooring of the washing area is made of synthetic resin boards, the flooring is made by adding one or two types of metal, ceramic, or other inorganic powders that have higher thermal conductivity than the resin to the synthetic resin.
By using a synthetic resin board mixed with at least one species, the thermal conductivity of the floor material can be increased and the floor can be heated more efficiently.

When a heat pipe is operated, it stretches in the axial direction due to linear expansion, and if the end of the heat pipe is formed by crimping the pipe, the end may bulge in the radial direction, etc. If the heat pipe expands in this way, there is a risk that the flooring or wall material that the end of the heat pipe is in contact with will be damaged. In this regard, if the end of the heat pipe is covered with an elastic material such as silicone rubber, even if the heat pipe expands, the elastic covering material will absorb the expansion and properly prevent damage to flooring and wall materials. be able to.

〔Example〕

1 to 3 show an embodiment of the first invention of the present application, where 1 is a bathtub, 2 is a washing area, and 3 is a floor thereof.

A plurality of heat pipes 4 are embedded inside the floor portion 3. On the other hand, on the outside lower part of the bathtub 1 on the washing water side,
A sealed pocket portion 5 is provided along the longitudinal direction of the bathtub. A solid or liquid heat medium 6 is sealed within the pocket portion 5 . And each heat pipe 4
The heat collecting part 41 (evaporating part) is inserted into the pocket part 5, and the entire circumference of the heat collecting part 41 is in contact with the heat medium 6. In contrast to the heat collecting section 41, a heat pipe portion located inside the floor section 3 constitutes a heat radiating section 42 (condensing section).

The heat medium 6 sealed in the pocket portion 5 may be a liquid such as water or oil, or a solid such as plaster or mortar. Note that, as described later, when the heat medium 6 is solid, the pocket portion 5 does not necessarily have to have a sealed structure.

According to the above embodiment, the heat medium 6 in the pocket part 5 is
It is heated by the heat of the hot water in the bathtub 1 through the bathtub wall. The heat collecting part 41 of the heat pipe 4 located inside the pocket part 5 is

4 to 6 show an embodiment of the second invention of the present application, which is similar to the embodiment described above in that a heat pipe 4 and a pocket portion 5 are provided, but inside the pocket portion 5,
A heat pipe 7 for heating the heat medium is arranged along the longitudinal direction, and a heat collecting part 71 of the heat pipe 7 is connected to the bathtub 1.

In this embodiment, one end of the heat pipe 7 is guided to the outside of the pocket portion 5, and is connected to the bathtub 1 so that a heat collecting portion 71 at the end comes into direct contact with hot water.

A mounting bracket 8 is fixed to the heat collecting part 71, and the heat collecting part 71
is connected to the side wall 101 of the bathtub 1 via this fitting 8. FIG. 6 shows the details. The cylindrical mounting bracket 8 has an inner diameter such that an appropriate gap S is formed between it and the heat pipe inserted into the tubular mounting bracket 8, and the tubular mounting bracket 8 has an inner diameter such that an appropriate gap S is formed between it and the heat pipe inserted into the tubular mounting bracket 8. The end portion 81, which should be located at the end portion 81, is configured to fit with the heat pipe. The heat pipe that is fitted and fixed to the end portion 81 has its heat collecting portion 71 located inside the mounting bracket 8 . The heat pipe 7 is connected to the bathtub 1 by fitting and fixing the mounting bracket 8 into a mounting hole 102 formed through the side wall 101. Since hot water from the bathtub enters the inside of the mounting bracket 8, the entire circumference of the heat collecting portion 71 can be brought into contact with the hot water, and heat can be efficiently collected from the hot water.

FIG. 7 shows another example of connection between the heat pipe 7 and the bathtub 1, in which the heat collecting plate 19 is fixed by welding or the like to the tip of the heat collecting part 71 penetrating the bathtub wall 101, and the heat collecting plate 19 is attached to the bathtub. It is installed so as to be in close contact with the inner wall. The heat pipe outside the bathtub has a flange portion 20 having a plurality of screw holes.
are provided, and the heat pipe 7 is fixed to the bathtub 1 by tightening fixing bolts 21 attached to each of the screw holes. Note that 22 is a sealing member provided between the attachment hole 102 and the heat pipe 7.

In addition, in the said connection structure, the heat collection plate 19 can also be made flush with the bathtub inner wall surface by providing a recessed part in the bathtub inner wall surface and fitting the heat collection plate 19 into this recessed part.

In addition, in FIGS. 6 and 7, the mounting bracket 8 and the heat collecting plate 19 are used to prevent the heat collecting part 71 from protruding into the bathtub 1, but the connection between the heat collecting part 71 and the bathtub 1 is The structure is not limited to this example, and can be any structure. Further, although the heat collecting effect is inferior, the heat collecting portion 71 of the heat pipe 7 may be structured so as to be in contact with or buried in the bathtub wall.

In the embodiments described above, the heat collecting part 71 of the heat pipe 7 for heating the heat medium collects heat from hot water in the bathtub and transfers it to the pocket part 5.
The heat is transmitted to the heat dissipation section 72 inside. Therefore, the heat medium 6 in the pocket part 5 is not only heated by the hot water in the bathtub 1 through the bathtub wall, but also heated by the heat pipe 7 for heating the heat medium, and as a result, the heat pipe 4 is heated by the heat pipe 7 for heating the heat medium. It is possible to increase the heat collection temperature and efficiently heat the floor 3.

8 and 9 show an embodiment of the third invention of the present application, which is similar to the embodiment shown in FIGS. 4 to 6 in that a heat pipe 7 is provided within the pocket portion 5. However, the heat pipe 7 collects heat from hot water in the middle of the hot water supply pipe from the reheating boiler.

In the figure, 9 is a reheating boiler, 10 is a hot water pipe between the boiler 9 and the bathtub 1, and a heat exchange chamber 11 is provided in the middle of the hot water pipe 10.
A heat collecting portion 71 of the heat pipe 7 is connected to the heat collecting portion 71 of the heat pipe 7.

FIG. 9 shows a connection structure of the heat collecting section 71 to the chamber 11, in which the end of the heat pipe that spans the heat collecting section 7 is inserted into the chamber 11 and brought into direct contact with hot water in the chamber 11. I have to.

Note that the connection structure of the heat collecting part 71 to the chamber 11 is also arbitrary. For example, as shown in FIG.
7 may be used for connection, or as shown in FIG. 11, a heat collecting plate 23 may be used for connection.

In FIG. 10, a fitting 17 is fixed to the heat collecting section 71, and the heat collecting section 71 is connected to the side wall 110 of the chamber 11 via the fitting 17. The cylindrical mounting bracket 17 has an inner diameter such that an appropriate gap S is formed between it and the heat pipe inserted therein, and the end portion 18, which should be located outside the chamber, fits into the heat pipe. It is configured to match. The heat pipe that is fitted and fixed to the end portion 18 has its heat collecting portion 71 located inside the mounting fitting 17 . The heat pipe 7 is attached to the mounting bracket 17.
is connected to the chamber 11 by fitting and fixing it into a mounting hole 111 provided through the side wall 110. Because the hot water in the chamber 11 enters the inside of the mounting bracket 17,
The entire circumference of the heat collecting portion 71 can be brought into contact with hot water.

Further, in FIG. 11, a heat collecting plate 23 is fixed by welding or the like to the tip of a heat collecting part 71 penetrating the chamber side wall 110, and the heat collecting plate 23 is provided in close contact with the inner wall of the chamber. The heat pipe outside the chamber is provided with a flange portion 24 having a plurality of screw holes, and the heat pipe 7 is fixed to the chamber 11 by tightening fixing bolts 25 attached to each of the screw holes. Note that 26 is a sealing member provided between the attachment hole 111 and the heat pipe 7. In the above connection structure, the heat collecting plate 23 can be flush with the inner wall of the chamber by providing a recess in the inner wall of the chamber and fitting the heat collecting plate 23 into the recess.

Although the heat collecting effect is inferior to those of the above embodiments, the heat collecting portion 71 of the heat pipe 7 may be structured to be in contact with or buried in the chamber wall.

In the above embodiment, the heat collecting part 71 of the heat pipe 7 collects heat from the hot water in the chamber 11 and transmits this heat to the heat radiating part 71 in the pocket part 5, which collects heat from the hot water in the bathtub 1. Since heat can be collected from hot water at a higher temperature than in the above embodiment, the temperature at which heat is collected by the heat pipe 4 can be further increased.

Furthermore, when additional heating by the boiler 9 is stopped, it becomes difficult for the heat collecting part 71 to collect heat, so the temperature of the hot water in the bathtub decreases less than in the above embodiment in which heat is collected from the hot water in the bathtub. .

12 and 13 show an embodiment of the fourth invention of the present application, which is similar to the embodiment shown in FIGS. 1 to 3 in that a heat pipe 4 and a pocket portion 5 are provided. , a heating mechanism 12 consisting of an electric heater is provided inside the pocket portion 5 along its longitudinal direction.

As this heating mechanism, any one that uses a heat source other than the hot water in the bathtub or the hot water to be supplied to the bathtub can be used. For example, a hot water pipe other than the bathtub type can also be used.

In the above embodiment, the heat medium 6 in the pocket part 5 is heated by the hot water in the bathtub 1 through the bathtub wall, and is also heated by the heating mechanism 12 arranged in the pocket part 5. Moreover, the heat of the heat medium 6 heated by the heating mechanism 12 in the pocket part 5 is.

Since the hot water is also transmitted to the hot water in the bathtub 1 through the bathtub wall, it is also useful for keeping the hot water in the bathtub 1 warm.

In the present invention, there is no limitation on the structure of the pocket portion 5, and it may be formed by fixing an angular member to the bathtub wall as shown in FIG. 3, or a cylindrical member as shown in FIG. It may be formed by fixing the shaped or tubular member 13 to the bathtub wall by means of fixing means 14. Further, when the heat medium 6 is solid, as shown in FIG. 15, the pocket portion can be an open type instead of a closed type. Further, the attachment position and length of the pocket portion 5 are not particularly limited, and the pocket portion 5 may be provided at the bottom of the bathtub, or may be provided at a portion in the longitudinal direction of the bathtub.

Further, the structure for attaching the heat pipe to the floor material is also arbitrary, and can be, for example, a structure as shown in FIGS. 16(a) to 16(c).

Among these, FIG. 16(a) shows an example in which the heat pipe 4 is fixed to the back surface of the flooring material 31 using the mounting bracket 15, FIG. 16(b) shows an example in which the heat pipe 4 is embedded in the back surface of the flooring material 31, and FIG. This is an example in which the heat pipe 4 placed on the back surface of the flooring material 31 is fixed with the surrounding filler material 16. In addition, other suitable configurations may be used, such as completely burying the heat pipe 4 inside the flooring material. can.

In the heating structure of the present invention, it is preferable that heat be efficiently radiated from the heat radiating portion of the heat pipe to the flooring material. 1st
Figures 7 to 2o show examples of the mounting structure of the heat pipe to the flooring material for this purpose. The heat pipe 4 is brought into contact with the back surface of the flooring 3 by using a metal holding plate 27 having a heat dissipating plate portion 272 with holes, and the holding plate 27 is made of resin 28 (for example, FRP resin). ) etc., which are fixed to the back surface of the flooring material 3.

Of these, the one shown in FIGS. 17 and 18 is the presser plate 2.
7, the heat dissipation plate portion 271 thereof is constituted by a plate-like member having a plurality of holes 273.

In addition, the one shown in FIGS. 19 and 20 has a presser plate 2.
7 is made of wire mesh.

Note that the holding plate 27 is made of resin, mortar, etc.
Can be attached to the back of the

According to such a structure, part of the heat radiated from the heat radiating part 42 is directly transmitted to the flooring material 3, and the other part is transmitted to the flooring material 3 via the metal holding plate 27. is,
This heats the floor. Since the heat dissipation plate portion 272 of the presser plate 27 is in close contact with the back surface of the flooring material 3,
A wide heat dissipation area can be secured between the flooring material 3 and the flooring material 3, and the flooring material 3 can be effectively heated.

In addition, the presser plate 27 also serves as a reinforcing material for the flooring material 3, and furthermore,
This is because the heat dissipation plate portion 272 has holes when it is fixed to the back surface of the flooring material with resin, mortar, etc.

Good adhesion to the flooring material 3 can be obtained.

Generally, the heat pipe 4.7 operates even when placed horizontally, but in order to ensure that the condensate flows back to the heat collecting part 41.71, the position of the heat collecting part 41.71 should be lowered. ,
It is also possible to add a slight inclination.

Furthermore, the heat pipe 4 extends in the axial direction due to linear expansion during operation, and if the end of the heat pipe is formed by crimping the pipe, the end may bulge in the radial direction or the like. If the heat pipe expands in this way, there is a risk that the flooring or wall material that the end of the heat pipe is in contact with will be damaged. In order to prevent such problems, it is preferable to cover the ends of the heat pipes 4 with an elastic coating material such as silicone rubber. As a result, even if the end of the heat pipe 4 stretches in the axial and radial directions due to expansion, the expansion is absorbed by the elastic covering material, causing damage to the flooring and wall materials that the end of the heat pipe 4 is in contact with. can be appropriately prevented.

Note that the structure and arrangement of the heat pipe are not limited to the above embodiments, and any type of heat vibrator including a conventionally known heat pipe can be used, and the arrangement thereof is also arbitrary. In addition, heat pipes are generally used with a perfectly circular cross section in order to withstand the pressure of the working fluid, but depending on the degree of pressure of the working fluid, heat pipes with a flat cross section can also be used. If such a heat pipe is used, the efficiency of heat dissipation to the flooring material can be further increased.

Further, the heat pipe may extend from inside the floor of the washing area to the wall side.

When the heating structure of the present invention is applied to a unit bath made of FRP, for example, as shown in FIGS. 21(a) and (b),
The installation can be easily carried out by manufacturing a separate floor member B with the heat pipe 4 fixed to the back side of the unit body A and assembling it to the unit body A at the location. .

〔Effect of the invention〕

According to the present invention described above, the following effects can be obtained,
This is extremely useful as a heating structure for bathroom floors in cold regions.

(1) There is no danger like electric heaters, and the floor of the washing area can be heated to an appropriate temperature using the heat of hot water in the bathtub.

(2) The manufacturing cost is low because the heat pipe only needs to be embedded inside the floor, and the usage cost is also low because no electricity is used.

(3) Unlike when hot water is used directly for floor heating, there is no performance deterioration due to freezing damage to pipes or scale build-up.

(4) The floor is automatically heated when taking a bath without requiring the operation of switches or valves.

(5) There is no need for a pump or a heating device, and since the heat pipe is pre-installed in the bath unit, there is no need for any special work such as electrical work.

In addition to the above effects, according to the second and third inventions of the present application, the heat medium in the pocket is not only heated by the hot water in the bathtub through the bathtub wall, but also heated by the heat medium in the pocket. Because it is heated by a heating heat pipe,
The heat pipe on the floor side can collect heat at a high heat collection temperature. In addition, especially in the third invention of the present application, since heat is collected from hot water in the middle of the hot water supply pipe, there is an advantage that the heat collection temperature by the heat pipe is high, and furthermore, when reheating is stopped, it is difficult to collect heat by the heat collecting part. Therefore, there is an advantage that the temperature of the hot water in the bathtub decreases less than when heat is collected from the hot water in the bathtub.

Furthermore, according to the fourth aspect of the present invention, the heat medium in the pocket is heated by the hot water in the bathtub through the bathtub wall and is also heated by the heating mechanism disposed in the pocket. Heat pipes can collect heat at a high heat collection temperature, and the heat of the heat medium heated by the heating mechanism is also transmitted to the hot water in the bathtub via the walls of the bathtub, so the hot water in the bathtub is It also has the advantage of helping to keep things warm.
