DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom unit, and more particularly to a floor heating device for a washing room.

[0002]

2. Description of the Related Art Conventionally, this type of bathroom unit with a floor heating device is provided with a washing place 2 adjacent to a bathtub 1 as shown in FIG.
As a method of manufacturing the heating device, as shown in FIG. 6, a glass fiber 4 is placed on a lower mold 3, a liquid of a synthetic resin is applied, dried and cured, and then a heater serving as an electric tubing heater 5 and a temperature control element 6 is formed. A heater is placed on the fiber-reinforced plastic by a so-called hand lay-up molding method in which a mr is placed, and further, a reinforcing material 7 is placed thereon, a glass fiber (not shown) is covered, and a synthetic resin liquid is applied and dried and cured. It was integrally molded. At this time, the terminal 8 of the heater 5 or the terminal 9 of the temperature control element 6 is made by making a hole in the glass fiber to be covered later.
The method of connecting to an external circuit through the hole was adopted.

[0003]

The construction of such a conventional floor heating system for a washing place has a disadvantage that the production process is complicated and most of the processes are performed manually, so that the cost is high. As a method of overcoming this drawback, a resin injection molding method can be considered, but in this case, there are problems such as treatment of lead wires and terminal portions and positioning of a heater unit, and it is difficult to adopt the resin injection molding method. there were.

An object of the present invention is to provide a bathroom unit with a floor heating device in a washing room, which can solve the above-mentioned problems, can be mass-produced, can be inexpensive, and has stable quality.

[0005]

According to the present invention, as a first means for achieving the above object, a lead wire on the back of a washing place is housed in a lead wire storage device having a substantially U-shaped cross section and wired. Further, as a second means, the connection terminal portion of the lead wire to the power supply connection wiring is housed in a sealed tube so that the terminal portion does not directly touch the resin even when integrally molded. Further, as a third means, the temperature control element is constituted by a thermostat, and the thermostat portion fixed to and protruded from the heater unit is inserted and fixed into a hole formed in the reinforcing member, thereby making the positioning of the heater unit simple and reliable. . Further, as a fourth means, an elastic body is attached to the terminal portion of the lead wire and is integrally formed.

[0006]

According to the first aspect of the present invention, the lead wires wired on the back surface of the washing place can be securely housed in the wiring housing clearance, and the pinch can be eliminated. Further, by the second means, after the lead wire connection terminal portion is integrally formed with the molded product, the connection with the power supply connection wiring can be easily performed. Further, the positioning of the heater unit is ensured by the third means, so that the positioning of the heater unit with the pattern on the surface of the washing area becomes possible. Further, by the fourth means, since the terminal portion of the lead wire has an elastic body at the time of injecting the resin, the resin does not turn around so much that the terminal portion of the lead wire can be easily taken out after molding.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. In FIG. 1, a preform 10 made in advance by fixing glass fibers with a binder and formed in a separate process is placed on a lower mold 3, and an electric tubing heater 5 is sewn on the preform 10. The ground 11 is placed. Reference numeral 12 denotes a thermostat as a temperature control element, which is adhered and fixed to the interlining 11. The interlining 1
A reinforcing member 7 composed of a plate portion 7a and a columnar portion 7b is placed on 1, and the thermostat 12 is fixed to a hole 13 formed in the reinforcing member 7. Further, the lead wire 14 is housed in the housing portion 15 having a U-shaped cross section mounted along the reinforcing member 7 through the hole 13 and wired as shown in FIG. Therefore, the lead wire is fixed at the time of molding, and the pinch and the like are eliminated.

Next, the terminal portion 16 of the lead wire 14 is housed in a sealed tube 17 as shown in FIG. 3 and put into an end frame 18 of the reinforcing member 7 as shown in FIG. An elastic body 19 having a thickness to be compressed by is placed. Therefore, the terminal portion 16 can be easily connected without touching the resin at the time of molding and can be easily connected to the elastic member 1.
In step 9, resin is prevented from entering during molding. After the above operation, the upper mold 20 is brought into contact with the lower mold 3, the reinforcing material 7 is partially held down, and the synthetic resin 21 is injected and integrally molded. This molding method is called a resin injection molding method. After taking out the molded product from the mold, the elastic body 19 is taken out, the tube 17 is taken out and externally connected, and the operation is completed. Since the heater 3 and the thermostat 10 are connected in series, it is not necessary to provide a lead wire separately from the heater and the temperature control element as in a conventional thermistor.

[0009]

As is apparent from the above description, according to the present invention, in producing a bathroom unit with a floor heating device in a washing room, a resin injection molding method which can be mass-produced and whose production cost is low is employed. Thus, the processing of the lead wires and the terminal portions, the positioning of the heater, and the like, which have been the problems of the above, can be solved, and it is possible to provide an inexpensive and stable bathroom unit.
