In the structure according to the second aspect of the invention, the heater board is set so as to be within the range of approximately 60 mm to 80 mm from the edge portion to the entrance opening and the bathtub. Even if the positional relationship of the openings is reversed, the same heater board can be used to heat the same area.

[0010]

Statistical Experiments to Achieve the Invention The bathroom unit of the present invention was born after careful consideration of the results of the statistical processing of the bather's flow line tracing in the bathroom washing room.
First, the outline of the method of this statistical experiment will be described. In this experiment, the trajectory of the bather's movement was first investigated in order to know the tendency and range of the bather's movement in the bathroom unit, especially in the washroom. Moreover, in order to determine the specific edge position of the heater board, a large number of subjects investigated the movement of the foot from a predetermined position, and estimated the moving distance of the foot by the method of statistical hypothesis test. Then, from these results, on the floor surface of the bathroom washing room, the area where human foot touches is covered, and the proper laying range of the heater board for reliable heating is determined. The layout of the cord heater, which is a linear heating element, was designed. Here, the laying range of the heater board generally refers to a region immediately below the floor surface of the washing place where the above code heater is arranged, and is used in the same meaning in the following description. This experiment consists of [1] flow line survey,
[2] It consists of determining the laying range of the heater board on the floor of the washing floor by analyzing the flow line.

Next, the structure of the bathroom unit used in this experiment will be described. This experiment was carried out when the entrance and exit openings were on opposite sides of the bathtub and when the entrance and exit openings were on opposite sides of the faucet wall. FIG. 3 is a layout diagram showing a layout relationship between the wash basin and the bath tub in the bathroom unit when the entrance opening is provided on the side facing the bath tub. As shown in the figure, in the bathroom unit, a bathtub portion A and a washing floor portion B subsequent thereto are integrally formed, and the shape of the waterproof pan 2 of the washing floor portion B is substantially rectangular. An entrance opening 6 is provided on the side facing the side of the bathtub section A adjacent to the washroom floor section B. Further, among the walls erected on the side edge of the wash floor B, other than the wall on the bath A and the entrance opening 6 side,
A faucet 7 is attached. FIG. 11 is a layout diagram showing a layout relationship between a wash basin and a bathtub in the bathroom unit in the case where the entrance / exit openings are provided on opposite sides of the wall having the faucet. Unlike the bathroom unit in the case where the bathroom unit has an entrance opening on the side facing the bathtub, the entrance opening 6 is different from the side facing the bathtub A side,
It is only provided on the side opposite to the wall on which the faucet 7 is attached.

[1] Flow line investigation When there is an entrance / exit opening on the opposite side of the bathtub In this experiment, in order to know which range needs to be heated when entering the bath and taking a bath, It was examined what kind of movement the person had before entering the room through the entrance / exit opening 6 and before retreating to the bath room. Results are shown in FIG.
This figure is a diagram extracted by dots from the flow line drawn by a person taking a bath in the bathroom. As can be seen from the figure, the places where the subjects stayed are gathered near the faucet 7 and the entrance opening 6.

When there is an entrance / exit opening on the side opposite to the wall with a faucet FIG. 13 is a diagram showing a flow line when entering a room and heading to a bathtub and a movement range when being in a washing room. As shown in the figure, when entering the room by opening the door from the entrance / exit opening 6, it is predicted that the user will turn toward the bathtub A through the vicinity of the central portion of the washing room and enter the bathtub A. Also, when washing the body in the washroom, sit on a chair near the faucet 7, and the movement range at this time is within a predetermined area, but this movement range is not directly related to the position of the entrance / exit opening 6. Conceivable.

[2] Determining the laying range of the heater board on the floor of the washing floor by the flow line analysis When there is an entrance / exit opening on the side opposite to the bathtub, the back side of the washing floor B related to this experiment will be described later. So that the heater board is attached. here,
As shown in FIG. 3, the edge of the heater board has a substantially rectangular shape. At this time, the distance from each side of the four sides constituting the washing floor B to the closest side of the rectangle showing the laying range of the heater board is the distance a on the side where the faucet 7 is provided, and the entrance opening 6 is provided. Side at distance b, faucet 7
The distance c is on the side opposite to the side having the tub, and the distance d is on the side having the bathtub. First, the minimum required distance for the distance b was investigated. That is, a person who wants to take a bath opens the door of the entrance / exit opening 6 of the bathroom, takes the first step to the floor part B of the washroom, and walks from the place where he / she touches the floor to the edge of the floor part B of the washroom. The required distance on the opening side was measured for many subjects. As a result, the maximum value 170
[Mm], minimum value 91 [mm], average value 127 [m
m] and the standard deviation was 21 [mm]. Further, when the population average was estimated with the reliability of 95%, the estimation range of the population average was 112 [mm] or more and 142 [mm] or less. From the above results, if the distance b is set to approximately 90 mm or more and 120 mm or less, the heater is installed at a place where the floor of the washing room B is stepped out of the entrance opening 6 of the bathroom and touches the floor with a reliability of approximately 95% or more. It turns out that you can think that it is within the laying range of the board.

Next, the minimum required distance d was investigated. That is, after bathing in the bathtub of the bathroom and warming up the body sufficiently, the bathtub-side required distance from the place where it reaches the floor to the edge of the washroom floor B is set to a large number after leaving the bathtub to the washroom side. Measurements were made on the subjects. As a result, the maximum value 164
[Mm], minimum value 65 [mm], average value 109 [m
m] and the standard deviation was 32 [mm]. Further, when the population average is estimated with the reliability of 95%, the estimated range of the population average is 81 [mm] or more and 138 [mm] or less. From the above results, if the distance d is approximately 60 mm or more and 80 mm or less, the location where the heater board is laid out with a reliability of approximately 95% or more, which comes out of the bathtub and drops the foot to the wash floor B to touch the floor. It turns out that you can think that it is within the range.

The distances a and c are determined in consideration of the manufacturing and construction conditions of the bathroom unit. First, the distance a
Is the distance on the side where the faucet 7 is installed, and when the person sits down on the chair and wash his body, his legs extend forward (the edge side of the wash floor B), so that the bathroom unit can be manufactured. The range should be as small as possible. Therefore, it is about 10 mm or more and 30 mm or less due to restrictions in manufacturing the bathroom unit. Since the distance c is the distance on the side of the wall where nothing is installed, it is approximately 70 m based on the results of the above flow line survey.
It should be m or more and 100 mm or less.

In the case where the inlet / outlet opening is provided on the side opposite to the wall having the faucet In this case also, the edge of the heater board has a substantially rectangular shape as shown in FIG. At this time, the washing floor B
The shortest distance from each of the four sides forming the heater board to the closest side of the rectangle indicating the laying range of the heater board is a distance a on the side having the faucet 7, a distance b on the side having the entrance / exit opening 6, and a bathtub. The distance c is on the side opposite to the side having the water vapor and the distance d is on the side having the bathtub. With respect to the distances b and d, the same result as when the entrance / exit opening is located on the opposite sides of the bathtub can be expected. Therefore, if the distance b is about 90 mm or more and 120 mm or less, the reliability is about 95% or more, From the entrance / exit opening 6 of the bathroom, wash floor B
It can be considered that the place where the user steps on the floor and touches the floor is within the laying range of the heater board. If the distance d is approximately 60 mm or more and 80 mm or less, the reliability of the bathtub is approximately 95% or more. It can be seen that the place where the person comes out of the floor and touches the floor by dropping his / her foot on the floor part B of the washing place can be considered to be within the laying range of the heater board. Regarding the distances a and c, the distance a is approximately 10 mm or more and 30 mm or less in consideration of the manufacturing and construction conditions of the bathroom unit as in the case where the entrance opening is on the side facing the bathtub. c is approximately 7
It is 0 mm or more and 100 mm or less.

As described above, from the result of determining the laying range of the heater board on the floor of the washing floor by the flow line investigation and the flow line analysis of this section, the edge of the heater board is located near the entrance opening of the bathroom. From about 90 mm to 120 mm, and near the bathtub from about 60 mm to 80 mm
Within, near the faucet, approximately 10 mm from the wall surface with the faucet
It can be seen that the above is set within 30 mm, and approximately 70 mm or more and within 100 mm from the wall surface without the entrance / exit opening, bathtub, or faucet.

Further, as shown in FIG. 2, the heater board 1 is sandwiched between the waterproof pan 2 on the upper surface and the underfloor member 3 on the lower surface so as to be sandwiched therebetween. As shown in the figure, the waterproof pan 2 is formed by applying a waterproof coating process by covering the surface of the FRP substrate 21 with a protective layer 22. In addition, underfloor material 3
The FRP floor surface material 32 is laminated on the upper surface of the heat insulating material 31. Here, the heat insulating material 31 is made of urethane foam and prevents heat from entering and exiting and also functions as a cushioning material that absorbs vibration and the like. The fixing material 5 is made of the same polyester resin or epoxy resin as FRP, which is the material of the member forming the waterproof pan 2, and the self-strengthening and soaking plate 12 after solidification.

Furthermore, among the walls erected on the side edges of the wash floor B,
A faucet 7 is attached to one wall other than the wall on the side of the bathtub portion A and the entrance / exit opening portion 6.

Next, the heater board according to this example will be described. In the heater board 1 of this example, the cord heater 14 which is a linear heating element is embedded in a serpentine shape on the upper surface of the substrate 11 which is a support of the cord heater 14 as shown in FIG. It has a structure in which a heat equalizing plate 12 for evenly transmitting the heat generated from the cord heater 14 to the waterproof pan 2 is arranged on the cord heater 14.
The substrate 11 and the heat equalizing plate 12 are integrally formed by laminating them in the same shape. Further, a code heater accommodating groove 13 for embedding the code heater 14 is provided on the upper surface of the substrate 11, and the code heater accommodating groove 13 is formed in the width direction of the substrate 11 (direction MN in FIG. 5). ,
For example, so that adjacent points are spaced at approximately 25 mm,
The board 11 is provided in a meandering shape in accordance with the laid shape of the code heater 14. Also, the substrate 1
, Are embedded in predetermined portions of the cord heater 14 so as to prevent heating of the code heater 14, and these overheat preventive devices 15, 15, ... Are recessed in the upper surface of the substrate 11. It is stored in the storage unit 16, 16 ... Further, the temperature controller 17 for adjusting the heat generation of the cord heater 14 is housed in a temperature controller housing portion (not shown) provided in the upper surface of the substrate 11 so as to be recessed. In addition, on the entire heater board 1, the soaking plate 12 is arranged in a grid-like manner at intervals of approximately 100 mm in each of the vertical and horizontal directions, avoiding locations where the code heater 14 is housed.
Also, an adhesive agent through hole (anchor hole) 4 for penetrating the adhesive agent 5 through the substrate 11 is formed. The adhesive 5 flows into the back surface of the substrate 11 through the adhesive through holes (anchor holes) 4, so that the waterproof pan 2, the heater board 1, and the floor base material 3 are securely fixed to prevent the floor from becoming flat. . Further, for the purpose of improving the heat transfer from the code heater 14 to the heat equalizing plate 12, a filling material 18 is sealed in the gap between the inner wall of the code heater housing groove 13 and the code heater 14.

The cord heater 14 is a flexible linear heating element in which a heating wire is wound around an insulating material and further coated, and its end portion is 100 V through a power supply connection terminal. It is designed to be connected to commercial power.
The substrate 11 is made of water resistant plywood having a thickness of about 9 mm in this example, and has a shape corresponding to the shape of the waterproof pan 2 to which the heater board 1 is attached. The soaking plate 12 is made of a metal plate such as copper, aluminum or iron having a high thermal conductivity,
Like the above, it is formed in a shape corresponding to the shape of the floor part of the washing place, and the thickness is preferably about 0.4 to 2 mm, and in this example, it is about 0.4 mm. In addition, in order to prevent leakage,
A ground wire is connected to the heat equalizing plate 12. The overheat protectors 15, 15, ... Are temperature-sensitive devices for preventing excessive heat generation of the cord heater 14 and ensuring safety. In this example, a thermostat composed of a bimetal and a thermal fuse is used. Has been. These overheat protectors 1
, 15 are inserted into predetermined positions of the cord heater 14 as a part of the electric circuit. The temperature controller 17 is a device for controlling the heat generation of the cord heater 14 and appropriately adjusting the temperature of the waterproof pan 2 according to the ambient temperature, the taste of the bather, etc., and a thermistor is used. As the filling material 18, a silicon rubber sheet, a silicon grease or the like having good heat resistance and thermal conductivity is used.

In this example, in the determination of the laying range of the heater board on the floor of the washing floor by the flow line analysis in the above-mentioned "statistical experiment leading to completion of the invention" (when the entrance and exit openings are on opposite sides of the bathtub) Based on the result, distances a, b, c, d
The cord heater 14 is arranged on the heater board 1 so that the length of the cord heater 14 becomes a predetermined length. That is, in this example, the distance b is about 100 mm, the distance d is about 80 mm, and the distance c is also the bathroom unit according to this example when the entrance opening is on the side opposite to the side including the faucet 7. So that it can be applied as is, approximately 100 mm, which is the same as the distance b, and
Since the distance a needs to be as small as possible within the range where the bathroom unit can be manufactured, it is set to about 20 mm in this example. In this bathroom unit, when the power supply side of the code heater 14 is turned on and the power is turned on, the code heater 14 generates heat, and the generated heat is supplied from the code heater 14 to the filling material 18.
The heat spreader 12 and the waterproof pan 2 are transmitted in this order, and at that time, the distance a is about 20 mm and b is about 100 mm from the edge of the washing floor B, which is the necessary laying range of the heater board.
The area in which c is approximately 100 mm and d is approximately 80 mm is
Since the code heater 14 is located immediately below it, the cord heater 14 is surely heated. Further, since the heat equalizing plate 12 has a high thermal conductivity and has substantially the same shape as the waterproof pan 2, heat can be quickly and uniformly applied to the heat equalizing plate 1.
The temperature of the waterproof pan 2 rises quickly and substantially uniformly as it travels through the inside of the container 2. According to the actual measurement, the temperature of the waterproof pan 2 rises at a rate of approximately 15 ° C. in 10 minutes, so it is sufficient to turn on the power supply side approximately 10 minutes before bathing. Furthermore, the substrate 11 that houses the code heater 14 is made of a material having a low thermal conductivity, and the outflow of heat is blocked by the underfloor material 3, so that the heat from the back surface side of the heater board 1 can be removed. Losses are low and therefore power consumption is low. In this bathroom unit, the fixing material 5 fills the space between the waterproof pan 2 and the heater board 1 and then the large number of fixing material through holes 4 formed in the heater board 1, and then the substrate 11 is further filled. Has flowed to the back side of and solidified. As a result, the heater board 1 is strongly adhered to the waterproof pan 2, and the solidified fixing material 5 in the fixing material through-hole 4 functions as if it were a rivet for rivet joining, so that the waterproof pan 2 and the heater board 1 are joined together. , And the soaking plate 12 constituting the heater board 1 are suppressed from moving between the contact surfaces, respectively, and as a result, peeling or floor squeal between the members is prevented. According to the above configuration, the result of the statistical experiment became clear,
Since the cord heater 14 of the heater board 1 is arranged immediately below the heating-required area in the waterproof pan 2, the area touched by the feet is reliably heated, and it is comfortable even in the severe winter season.
Further, since the code heater 14 is not arranged outside the required range, it is useful for saving wiring and reducing power consumption.

As shown in FIG. 9, a large number of slit holes 23a, 23a, ... Are provided all over the entrance / exit opening 6 side of the wash floor and the entire edge portion on the bathtub side.
The drainage gutters 23, 23 covered with the attached top cover are provided, and the width of the drainage gutter 23 is 120 m at the entrance opening 6 side.
m and 80 mm on the bathtub side. According to the above configuration,
Since a drainage channel is also provided on the bathtub side, for example, when a person enters a full bathtub and a large amount of hot water overflows from the bathtub, the water will be drained quickly, so it will pass through the washroom to the floor of the dressing room. It does not extend.

Sixth Embodiment FIG. 10 is a plan view of the floor part of the bathroom of the bathroom unit according to the sixth embodiment of the present invention. The bathroom unit in this example
What is different from that of the above-described fourth embodiment (FIG. 8) is that the entire area of the edge portion of the floor part of the washroom on the side of the entrance / exit opening 6 is
Whereas the drainage groove 23 having a constant width b _{1 of} about 120 mm is provided, the drainage groove 23 is provided over the entire edge portion on the entrance opening 6 side of the wash floor, but the width of the drainage groove 23 is
The width b ₁₁ in the vicinity of the entrance / exit opening 6 is narrowed by a predetermined width from about 120 mm, and the width b _{12 in} the area other than the vicinity of the entrance / exit opening 6
The point is that the width is wider than approximately 120 mm by a predetermined width. As shown in FIG. 10, a large number of slit holes 23 are formed in the upper lid over the entire edge portion on the entrance opening 6 side of the wash floor.
The drainage groove 23 having a, 23a, ... Is provided, and the width of the drainage groove 23 is only the area of the predetermined length W on the washing place side of the entrance opening 6 and the width b ₁₁ is a predetermined width from approximately 120 mm. The width is narrow and the width b ₁₂ is approximately 120 mm in the area other than the area having the predetermined length W near the entrance / exit 6 of the floor of the washroom.
The width is wider by a predetermined width. At the stage of drainage design, when it is found that the width of the drainage groove 23 provided on the peripheral portion of the entrance / exit opening 6 side of the washing floor is insufficient at about 120 mm, the drainage groove 23 is excluded except for the vicinity of the entrance / exit opening 6. The drainage capacity of the drainage groove 23 is improved by slightly widening the width of the drainage groove 23. Setting the width of the drainage groove 23 to approximately 120 mm is a condition for securing the laying range of the heater board, but in reality, it is not necessary that all of them have a constant value. It is considered that the region other than the vicinity of the entrance / exit opening 6 does not have a flow line at the edge of the part on the entrance / exit opening 6 side. Therefore, as in this example, the laying range of the heater board is the above-mentioned statistical It is possible to produce a part that is partially narrower than the range obtained as a result of the experiment.

The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific structure is not limited to this embodiment, and there are design changes and the like within the scope not departing from the gist of the present invention. Also included in the present invention. For example, in the embodiment of the present invention, a cord heater in which a heating wire is wound around an insulator as a heating element and further coated is used, but conductive fibers such as carbon fibers are formed into a plate shape by a thermosetting resin. A solidified product, a product utilizing infrared heating, or a hot water pipe may be used. Further, although a silicon rubber sheet, silicon grease, or the like is used as the filling material, it may be a layered metal foil or a bent metal plate. Further, an elastic body made of foamed resin or the like may be enclosed between the code heater and the substrate so that the code heater comes into direct contact with the heat equalizing plate. In addition, for example, in the first embodiment, the shortest distances a, b, c, d from each of the four sides forming the washing floor to the closest side of the rectangle formed by the edges of the heater board are omitted. 20 mm, approximately 100 m
m, about 100 mm, about 80 mm, but not limited to this distance, as long as it is a value within a predetermined range, and within a range that can be judged from the result of the preceding paragraph, slightly above the predetermined range May exceed. Further, the figures formed by the edge of the wash floor and the heater board are both substantially rectangular, but the shape is not limited to this, and polygons other than rectangles, circles, and figures having any curved line as the periphery may be used. .
Further, the heater board does not have to be one sheet over the entire laying range, and may be divided into a plurality of parts. Further, in the third to sixth embodiments, the case where the entrance / exit opening is on the side opposite to the bathtub is dealt with, but the case where the entrance / exit opening is on the side opposite to the wall provided with the faucet is also
This is similar to the case of the embodiment. Further, in the fourth and fifth embodiments, the drain groove may be provided on the wall side provided with the water faucet or on the side opposite to the wall. In the sixth embodiment, the wall provided with the water faucet may be provided. The drainage groove may be provided on the side, the side facing the wall, or the bathtub side.

[0030]

As described above, according to the constitution of claim 1, the heating element of the heater board is arranged immediately below the range of heating in the floor of the bathroom washing room, which is clear as a result of the statistical experiment. Because it is heated, the area touched by the foot is heated reliably, and it is comfortable even in the severe winter season. Also, since the heater board is not laid outside the area where heating is required,
This saves the heater board and the heat source. Further, according to the configuration of claim 2, even when the positional relationship between the bathtub and the entrance opening is reversed, the same heater board can be used to heat the same area, so that a different kind of heater board can be used. You can save the work of making. In addition, if a drainage groove is provided in the peripheral part where the heater board is not laid in the floor part of the washing room, it can be applied to a bathroom unit in which no step is formed between the dressing room and the adjoining room.
