DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing pan used for a system bath or the like, and more particularly to a washing pan capable of heating a floor of the washing pan.

[0002]

2. Description of the Related Art When taking a bath in the winter, many people experience that the washing pan often feels very cold and unpleasant. A device configured to be able to heat the floor is known.

[0003] This conventional washing pan that can heat floors is
At the time of molding by the hand lay production method (HLU) or the spray production method (SLU), a heating heater was attached to the intermediate layer and the molding was performed (called a sandwich method). In addition to the problem that the cost is considerably increased, the hand-lay manufacturing method (HLU) and the spray manufacturing method (SL)
In the case of the molding by U), there is a problem that the working environment is very easily polluted because the material is sprayed and molded.

[0004] The present invention has been made in view of the above situation, and an object of the present invention is to provide a floor heating that can be easily manufactured in a short time under a very clean working environment. It is intended to provide bread for washing.

[0005]

In order to achieve the above object, according to the present invention, after a washing pan is provided with a plurality of heating elements arranged in a lower mold, a low pressure S is applied to the upper surface of these heating elements.
The MC or low-pressure BMC material is placed, and then the upper and lower molds are closed and the low-pressure SMC or low-pressure BMC material is rolled into a desired washing pan shape. It is characterized by simultaneous molding with a material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to an embodiment shown in the accompanying drawings.

FIG. 1 shows an example of manufacturing a washing pan 1 according to this embodiment. A plurality of PTC heaters (Positive Tempareturtur) are provided between a plurality of rib grooves 3 formed in a lower mold 2.
A plurality of shallow heater grooves 5 into which approximately lower halves of eCofficient Tharmisters 4 are fitted are formed. As the PTC heater 4 used in this embodiment, a known waterproof insulation type semiconductor PTC heater is used.

Using the lower mold 2 thus formed, FIG.
In the case of manufacturing the washing pan 1, the required number of PTC heaters 4 are first fitted into the heater grooves 5 at required intervals, and then the low pressure SMC is
(Sheet Molding ConpoundMethod) The plate material 6 is placed.

Next, by lowering the upper mold 7 and closing the lower mold 2 and pressurizing it at a required temperature and pressure, as shown in FIG. Face 8
The washing pan 1 having a desired shape is simultaneously formed in a state where the washing pan 1 is buried in the lower surface of the washing machine.

Thus, in this embodiment, the low-pressure SMC
Since the PTC heater 4 can be attached to the lower surface of the floor 8 of the washing pan 1 at the same time as the plate material 6 is press-formed, the washing pan 1 that can easily heat the floor in a short time can be manufactured. Further, the use of the low-pressure SMC plate member 6 can effectively prevent breakage of the PTC heater 4 during press forming.

In this embodiment, the low pressure SMC plate 6 is manufactured by press molding instead of the conventional hand lay manufacturing method (HLU) or spraying method (SLU) in which a material is sprayed and formed. In addition, the work can be performed in a clean environment without fear of scattering of materials.

As is well known, since the PTC heater 4 has a small heating / heating area, in order to increase the heating / heating area, a metal powder having a high thermal conductivity, such as a metal powder having a high thermal conductivity, is previously placed in the low-pressure SMC plate 6. It is desirable to mix aluminum powder with aluminum powder or to use an aluminum plate 9 as shown in FIG.

The aluminum plate 9 is formed of a strip-like long piece. Anchor holes 10 are punched out at required intervals along the longitudinal direction, and the low-pressure SMC plate material 6 enters the anchor holes 10. It is configured so that an anchor effect can be obtained by filling with.
The PTC heater 4 is joined to a plane portion between the anchor holes 10 of the aluminum plate 9 as shown in FIG.

The aluminum plate 9 with the PTC heater 4 formed as described above is set on the lower die 2 as shown in FIG.
The MC plate 6 is placed, the upper die 7 is lowered, and the lower die 2 is closed to form the aluminum plate 9 and the PTC.
The heater 4 is buried in the low-pressure SMC plate 6, and heat from each PTC heater 4 is transmitted to a wide range through each aluminum plate 9.

When the PTC heater 4 or the aluminum plate 9 is inserted during the formation of the low-pressure SMC plate 6, the sink is generally easily generated, which is not preferable in appearance.

Therefore, as a countermeasure against "sink", this method uses a tile pattern of the washing pan 1 as shown in FIG. 5 or affixes a tile to the surface side, as shown in FIG. The aluminum plate 9 with the PTC heater 4 fitted to the tile pattern is inserted into the low-pressure SMC plate 6 via the spacer 11 so as to prevent the appearance of “sink” from appearing.

The washing pan 1 thus manufactured
Finally, a power cord (not shown) is connected to each PTC heater 4 and installed on a system bus or the like.

Of course, in the present invention, a known flat plate heater or a fibrous surface heater can be used in place of the PTC heater 4 used in the above embodiment. When using these flat heaters or fibrous surface heaters, the shallow heater grooves 5 of the lower mold 2 are filled in advance and flattened, so that these flat heaters or fibrous surface heaters are performed in exactly the same procedure as described above. To low pressure S
It can be mounted on the MC plate 6. Further, in the present invention, a low-pressure BMC material (Bul
The same effect can be obtained by using the k Molding Compound Method).

[0019]

Since the washing pan according to the present invention is configured as described above, it is possible to easily manufacture a washing pan capable of heating the floor under a very clean working environment in a short time. Can be obtained.
