BACKGROUND OF THE INVENTION
The present invention relates to a heat radiating plate used for bathroom heating and a construction method thereof. More particularly, the present invention relates to a radiator plate used for preparing a bathroom washroom floor that can be heated, and a method for constructing a bathroom washroom floor that can be heated using the radiator plate .
[0002]
[Prior art]
Conventionally, various heating technologies have been proposed and put into practical use for the purpose of improving the comfort of living spaces in structures such as cold seasons in cold regions and houses in cold regions. Most of them are placed on the floor of the living space. The base material is a foamed synthetic resin plate or wood plate, and a groove is engraved on one side of the plate. And a floor heating panel having a structure in which these surfaces are covered with a flexible thin plate such as an aluminum foil.
[0003]
There is a similar demand for improving comfortability by using heating technology in bathroom dressing and washing areas. People suffering from high blood pressure, a type of lifestyle-related disease, and elderly people not only feel uncomfortable when bathing clothes and washrooms are cold, but also due to blood pressure fluctuations caused by sudden drop in body temperature. There was an accident. The bathroom dressing room can be made a heated floor by arranging a floor heating panel with a small area, but it is difficult to make the bathroom washing room floor a heated floor.
[0004]
In order to use the floor of the bathroom washer as a heating floor, a method of sticking a planar heating element to the back surface of the floor of the bathroom washer has been proposed (see Patent Document 1). However, in many cases, the bathroom has a unit structure including a bathtub and a washing area. In the unit bath, many of the bathtub and the washing area are formed by a sheet molding compound (SMC) method, and a lattice ( (Vertical and horizontal) Since the ribs are integrally formed, there is a disadvantage that the sticking work is complicated when the sheet heating method is applied to the back surface of the floor.
[0005]
In addition, a method of arranging the heating medium tube in a meandering manner is also conceivable, but when this method is used, the rib is removed (destroyed) only in the part where the heating medium fluid tube is arranged on the lower surface of the floor, and the removed part is removed. A heat transfer fluid tube will be arranged. However, the grid-like (vertical and horizontal) ribs formed on the lower surface of the floor are formed for the purpose of reinforcing the floor of the washing place, so that the floor of the washing place is easily deformed if removed. For this reason, in order to reinforce the lower surface of the floor where the heat transfer fluid tube is disposed, it is necessary to separately attach a reinforcing metal plate, and there is a disadvantage that not only the mounting work is complicated, but also the cost is greatly increased.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail. The heat sink according to the first aspect of the present invention is used for preparing a floor surface of a bathroom that can be heated and a washing floor surface of a bathroom . The heat radiating plate is formed by a sheet molding compound (SMC) method, and has lattice-like (vertical and horizontal) ribs formed on the lower surface of the floor . In the SMC method, a reinforcing fiber having a length of 10 to 20 mm in a roving shape is mixed with a resin to form a sheet. The sheet is placed in a mold, cured by pressing and heating, and then released to obtain a product. Say the law. Examples of resins that can be used include unsaturated polyester resins, epoxy resins, and vinyl ester resins. Examples of the reinforcing fiber include glass fiber, carbon fiber, and selanmic fiber. Among these, glass fiber is preferable. The ratio between the resin and the reinforcing fiber can be a ratio that is usually employed when manufacturing a unit bath or the like.
[0012]
The floor surface of the bathroom washroom formed by the SMC method may be formed as a structure in which a part of the outer wall of the bathtub is connected, but the outer wall of the bathtub is formed as a structure that is not connected, and the post-processing method is used for the bathtub. It is preferable to connect to the outer wall. The floor area of the bathroom washer is 80 cm to 300 cm × 80 cm to 300 cm, and the floor surface is usually rectangular. Grid-like ribs are integrally formed on the lower surface of the bathroom washroom formed by the SMC method. This lattice-shaped rib means a structure in which a plurality of vertical ribs (one rib) and a plurality of horizontal ribs (ribs orthogonal to the vertical ribs) are combined at a right angle. The thickness of the floor of the washroom ranges from 2 mm to 10 mm, the thickness of the grid ribs ranges from 2 mm to 10 mm, and one grid rib space surrounded by vertical and horizontal ribs ranges from 5 cm to 15 cm. The height of the grid ribs can be selected in the range of 10 mm to 60 mm. The height of the grid ribs is preferably the same, but the spaces surrounded by the vertical ribs and the horizontal ribs do not have to be the same size. It can also be made smaller than the space of the part.
[0013]
The heat sink according to the first aspect of the present invention is a combination of a plurality of heat sinks fitted in lattice ribs integrally formed on the floor surface of a bathroom washroom formed by the SMC method. The heat sink exerts the function of transferring heat from the lower surface to the floor surface of the washroom. The heat sink is a unit (sheet) of a heat-sink tube embedded in one surface of a long and narrow foamed synthetic resin plate and a metal foil attached to the surface of the heat-sink tube. A heat radiating plate is formed by connecting a plurality of units (sheets) of heat radiating plates by a continuous heat medium tube.
[0014]
Synthetic resins constituting the foamed synthetic resin plate include polyamide resins such as polyamide 6, polyamide 6 · 6, polyamideimide, polyolefin resins such as polyethylene, polypropylene and ethylene-propylene copolymer, polyethylene terephthalate, polybutylene terephthalate. And polyester resins such as polyvinyl chloride, polyurethane, polystyrene, and ABS resin. The expansion ratio of the foamed plate-like body prepared from these synthetic resins is preferably about 1.5 to 80 times. The foamed synthetic resin plate is a long narrow rectangle having a length of 90 cm to 250 cm, a width of 10 cm to 30 cm, a thickness of 10 mm to 50 mm, and a size larger than the outer diameter of the fluid tube. The lengths of the foamed synthetic resin plates need not all be the same. That is, since it is not necessary to dispose a heat radiating plate at a portion where an outlet for flowing washing water or the like is provided, the foamed synthetic resin plate hitting this portion can be made shorter than the other portions.
[0015]
On both ends of the foamed synthetic resin plate in the width direction, heat medium tube burying grooves are made parallel to the length direction of the foamed synthetic resin plate and opened at both ends in the lengthwise direction. To do. The buried groove has a U-shaped cross section cut at right angles to the direction in which it extends, and its opening and depth are the same or slightly smaller than the outer diameter of the heat transfer medium tube. preferable. The reason why the heat medium tube embedded groove is opened at both ends of the foamed synthetic resin plate in the length direction is to guide the heat medium tube embedded in the embedded groove to the outside of the foamed synthetic resin plate and to change the direction outside. That is, at one end in the length direction of the foamed synthetic resin plate, it is exposed with a margin in length, formed into a U shape, changed in direction, returned to the buried groove of the same foamed synthetic resin plate, and the U shape at the other end This is because the U-shaped part having a longer exposed portion is formed to change the direction and lead to the buried groove of another foamed synthetic resin plate (see FIG. 1 and FIG. 7 described later).
[0016]
The heat medium tube embedded in the embedded groove functions to circulate the heat medium in the inner space and supply heat to the outside, such as flexibility, mechanical strength, heat resistance, chemical resistance, etc. Need to be excellent. Examples of the heat medium tube exhibiting such characteristics include a crosslinked polyethylene tube, a polybutene tube, a polypropylene tube, and a resin tube in which a metal wire is embedded in the wall surface of the tube. Among these, a crosslinked polyethylene pipe and a polybutene pipe are preferable. The diameter of the heat transfer tube varies depending on the thickness of the floor surface of the bathroom washroom, the density of the heat transfer tube, the type of the heat transfer medium, the amount of circulation of the heat transfer medium, the temperature of the heat transfer medium, etc. Is 5 to 25 mm, and the inner diameter is 3 to 20 mm.
[0017]
Examples of the heat medium that circulates inside the heat medium tube include hot water, water vapor, and oil. The heat medium is circulated to the heat medium tube via the header by adjusting the temperature and pressure with a heat medium circulation device. The heat medium circulating device is preferably installed in the vicinity of the bathroom, for example, under the floor, outdoors, on the roof, on the veranda.
[0018]
The metal foil attached to the surface of the heat transfer medium tube supports and fixes the heat transfer medium tube embedded in the embedded groove of the foamed synthetic resin plate from the side of the embedded groove, and heat from the heat transfer medium tube is used for washing in the bathroom. It performs the function of transferring heat to the floor. Examples of the metal foil include metal foil such as aluminum foil, tin foil, copper foil, and stainless steel foil. Among these, aluminum foil is most preferable from the viewpoint of ease of manufacture and cost. If the thickness of the metal foil is too thin, the strength will be insufficient and it will be easily damaged, and if it is too thick, the weight of the product will increase and the cost will increase, and it will be difficult to form the notches described later. It is preferable to select within the range. The interface between the foamed synthetic resin plate and the metal foil is preferably bonded with an adhesive interposed. In addition, when the metal foil is pasted on the portion of the foamed synthetic resin plate that extends from the periphery of the opening portion to the bottom of the U-shaped groove, the heat medium tube is embedded in the direction in which the embedded groove extends. It is preferable because the heat from can be efficiently transferred to the metal foil adhered to the surface of the heat medium tube.
[0019]
The heat sink is a unit (sheet) of a heat-sink tube embedded in one surface of a long and narrow foamed synthetic resin plate and a metal foil attached to the surface of the heat-sink tube. A heat radiating plate is used, and a plurality of units (sheets) having such a structure are connected by a continuous heat medium tube. In the central portion that bisects a plurality of units (sheets) of heat radiating plates, the exposed heat medium tube has a dimension longer than the length of the lattice vertical ribs forming the lattice ribs. At the portion where the heat medium tube is exposed for a long time, the entire bisected heat sink unit is changed in direction (see FIG. 8 described later). Multiple units (sheets) of heatsinks are connected by a single continuous heat transfer tube, and the heatsinks are heated to a uniform temperature as a whole by combining the heatsink units with the half of the heatsinks turned around at the center. can do.
[0020]
On the other surface (back surface) of the foamed synthetic resin plate constituting the heat sink, between the two parallel fluid tube embedding grooves engraved on one surface (front surface), along the heat medium tube embedding groove Engrave two V-shaped cuts. This V-shaped cut does not damage the foamed synthetic resin plate when one unit (sheet) of the heat sink is bent into a bowl shape with the metal foil sticking surface outside (see FIGS. 3 to 6 below). The V-shaped angle of the V-shaped cut is preferably around 90 degrees (see FIG. 1 described later). The position where the V-shaped cut is provided is preferably a position where the fluid tube does not contact the grid rib when the heat sink is fitted into the grid rib on the lower surface of the bent floor (see FIG. 10 described later).
[0021]
The heat radiating plate has a cut portion penetrating the foamed synthetic resin plate and the metal foil between the two heat medium tube embedding grooves, perpendicular to the two V-shaped cuts, and The same number of grid ribs as that of the grid horizontal ribs inserted into the grid horizontal ribs are provided (see FIG. 1 to be described later). The notch portion is for fitting a grid lateral rib formed on the floor lower surface when the heat sink is bent into a bowl shape and fitted into the grid rib formed on the floor lower surface. The length of the cut portion is larger than the interval between the two V-shaped cuts, but smaller than the interval between the two heat medium tube burying grooves.
[0022]
Next, a method for constructing the heating floor structure will be described. First, we prepared and prepared a bathroom washroom floor surface that was formed by the sheet molding compound (SMC) method and was integrally formed with grid-like (vertical and horizontal) ribs on the lower surface, and was described in detail above in parallel. Prepare and prepare a heat sink. Turn the bathroom wash floor above.
[0023]
Next, one unit (sheet) of the heat radiating plate is bent into a bowl shape with the metal foil adhering surface outside (see below, FIG. 4 and FIG. 6), and the grid horizontal ribs on the lower surface of the floor at the cut portion of the heat radiating plate , The side of the heel is in contact with the grid-like vertical ribs, and the top surface of the heel (metal foil attachment surface) is in contact with or close to the plane surrounded by the grid-like (vertical and horizontal) ribs. Fit into the rib-shaped space. The heat from the heat sink can be efficiently transferred to the bathroom floor by bringing the upper surface of the ridge into contact with or close to a plane surrounded by grid-like (vertical and horizontal) ribs.
[0024]
Subsequently, the other heat radiating plate units connected by the heat radiating plate and the fluid tube are sequentially fitted into the odd-numbered lattice rib space portions in the ascending order in the same procedure as above. Finally, the entire heat sink unit is redirected at the part where the fluid tube is exposed for a long time, and in the descending order, the other heat sink units connected to the heat sink unit by the fluid tube are the same procedure as above. Then, the other heat sink units are sequentially fitted, and the surface on which the heat sink is fitted is set as the surface side, so that the bathroom washroom floor can be obtained.
[0025]

In the figure, 1 is a foamed polystyrene plate having a thickness of 20 mm, a width of 25 cm, and a length of 90 cm, and the same thickness, width, and length of 70 cm. 2 is a heat medium tube embedded with a width of 7.2 mm and a depth of 7.2 mm. It is a groove, and the distance between them is 21 cm at a position 20 mm from the width direction end of the expanded polystyrene plate. In the heat medium tube embedding groove 2, a cross-linked polyethylene heat medium tube 3 having an outer diameter of 7.2 mm was embedded, and an aluminum foil 4 having a thickness of 100 μm was stuck on the upper surface thereof. The heat medium tube embedding grooves 2 are engraved at both ends in the width direction of one surface of the expanded polystyrene plate 1 in parallel along the length direction of the expanded polystyrene plate and opened at both ends in the length direction. Has been. In the figure, the heat medium tube burying groove 2 and the heat medium tube 3 appear to overlap each other.
[0028]
The heat transfer tube is exposed at one end of the expanded polystyrene plate 1 with a margin in length to form a U-shape (3a), change the direction, and return to the buried groove of the same expanded polystyrene plate. The other end was exposed longer than the U-shape to form a U-shape (3b) to change the direction, and led to another expanded polystyrene plate (see FIG. 7). While the exposed length was made longer than the U-shape (3a) and connected to another expanded polystyrene plate, the heat sink unit for the latter half was fitted (see FIG. 9).
[0029]
Although the heat sink composed of a plurality of units is connected by a single heat medium tube 3, the heat medium tube (3c) at the center part is divided into two at the center part, and is longer than the length of the heat sink at the center part. The dimensions were long (see FIG. 7). This is to make it possible to change the direction of the heat dissipation plate composed of a plurality of units at the central portion so that the heat medium tube 3 does not buckle.
[0030]
Between the two fluid tube embedding grooves 2 formed on the one surface on the surface of the expanded polystyrene plate 1 to which the aluminum foil 4 is not adhered, the distance between the two is 7 cm and the two are disposed along the heat medium tube embedding groove 2. A V-shaped cut 5 of the book was engraved. As described above, the V-shaped cut 5 functions so that the foamed polystyrene plate is not damaged when the foamed polystyrene plate 1 is bent into a bowl shape with the aluminum foil sticking surface of the foamed polystyrene plate 1 facing outside.
[0031]
Each unit of the plurality of heat radiating plates was provided with the same number of cut portions 6 as the lattice horizontal ribs 9 penetrating the aluminum foil 4 of the expanded polystyrene plate 1. The lattice ribs 9 have a width of 5 mm and a length of 90 mm, and are perpendicular to the V-shaped cut 5 and have the same interval as the interval between the adjacent lattice ribs 9. The incision 6 is made shorter than the interval between the medium tube burying grooves 2, and the expanded polystyrene plate 1 is bent into a bowl shape with the aluminum foil sticking surface outside, along the lattice vertical ribs 8 on the lower surface of the bathroom washroom floor. When installing, the grid horizontal ribs were fitted. By doing so, the side surface 7 of the ridge can be brought into contact with the lattice vertical ribs, and the upper surface (metal foil attaching surface) of the ridge can be brought into contact with or close to a plane surrounded by the lattice-like (vertical and lateral) ribs. As described above, the heat from the heat radiating plate can be efficiently transferred to the bathroom floor by bringing the upper surface of the ridge into contact with or in close proximity to a plane surrounded by grid-like (vertical and horizontal) ribs.
[0032]
90 mm x 90 mm grid ribs (thickness 5 mm, height 40 mm) formed integrally on the lower surface of the bathroom washing floor 10 at right angles to the grid vertical ribs 8 with the heat sink fitted. FIG. 10 shows a partially enlarged longitudinal sectional view when cut. In FIG. 10, the lattice rib space is formed by bringing the side surface of the ridge into contact with the lattice vertical ribs 8 and the upper surface (metal foil attachment surface) of the ridge is in contact with or close to a plane surrounded by the lattice (vertical and horizontal) ribs. The state where it is fitted in the part is shown.
[0033]
In order to fit the heat sink in the space part integrally formed on the lower surface of the bathroom washroom floor, first, as shown in FIG. The other heat radiating plate units connected by the heat medium tube were sequentially fitted in the same procedure as above. Next, in the portion (3c) where the heat medium tube is exposed for a long time, the entire remaining heat radiating plate unit is turned (see FIG. 8). The other heat radiating plate units connected by the fluid tube were sequentially fitted in the same procedure as above (see FIG. 9). Heating is possible by placing the heat sink plate on the front side and placing the left and right ends of the washing floor on the bathroom pedestal, and connecting both ends of the heat transfer tube to the connecting pipe from the heat transfer device. A floor surface was obtained.
