a) Field of the Invention
The present invention relates to a toilet seat heating device and more particularly to forming methods of a toilet seat which is integrally formed with a heating wire and products thereof.
b) Description of the Prior Art
A toilet used now is primarily constituted by a bowl and a water tank. As being primarily a ceramic product, the bowl will provide an ice cold feeling. Therefore, an upper side of the bowl will be usually added with a plastic toilet seat to overcome the ice cold problem. However, when air temperature drops, the plastic toilet seat is still rather cold. Thus, there are vendors who use water heating pipes to allow temperature of the toilet seat to close to that of a human body, so that people can be more comfortable when using the toilet.
The primary object of the present invention is to provide forming methods of a toilet seat which is integrally formed with an embedded heating wire, wherein the heating wire is embedded in the toilet seat using primarily a plastic material or glass fiber reinforced plastic, thereby forming the toilet seat which is integrally formed with the embedded heating wire.
An aforementioned forming method using the plastic material to embed the heating wire includes following steps:
An aforementioned forming method using the plastic material to embed the heating wire includes following steps:
In the aforementioned forming method, the said bottom layer can be plate-shaped plastic or plate-shaped wood.
An aforementioned forming method using the glass fiber reinforced plastic to embed the heating wire includes following steps:
The aforementioned forming methods using the plastic material to embed the heating wire can utilize one of the forming methods including compressing, extrusion, transferring and casting; whereas, the forming method using the glass fiber reinforced plastic to embed the heating wire can use stack compressing.
The present invention provides a toilet seat which is integrally formed with an embedded heating wire, with the said toilet seat being provided between a bowl and a toilet cover. The present invention is characterized in that the said toilet seat includes structures which are constituted by plastic and the heating wire embedded by the plastic, whereas the said heating wire contacts completely with the plastic without leaving a gap, thereby forming the integrally formed toilet seat.
Additionally, the present invention provides a toilet seat which is integrally formed with an embedded heating wire, with the said toilet seat being provided between a bowl and a toilet cover. The present invention is characterized in that the said toilet seat includes structures which are constituted by plastic, plate-shaped plastic and the heating wire embedded by the plastic and plate-shaped plastic.
On the other hand, in the aforementioned toilet seat which is integrally formed with an embedded heating wire, the said heating wire is preferably located at an upper part of the toilet seat and adjacent to a surface of the toilet seat.
To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.
Referring to
The toilet which is integrally formed with the embedded heating wire, according to the present invention, is characterized in that the heating wire S2 is embedded in the toilet seat S and contacts with the toilet seat S completely without leaving a gap; whereas, the heating wire S2 is preferably located at an upper part of the toilet seat S. As the heating wire S2 is adjacent to a surface of the toilet seat S, heat can be quickly conducted to the surface to provide a warm toilet seat.
The toilet seat which is integrally formed with the embedded heating wire, according to the present invention, uses primarily a plastic material or glass fiber reinforced plastic to embed the heating wire, thereby forming a toilet seat which is integrally formed with an embedded heating wire.
In the aforementioned forming methods that use the plastic material to embed the heating wire, the said plastic material includes an adhesive agent, a filler and pigment. The said adhesive agent can be thermosetting resin or thermoplastic resin, optionally; the said thermosetting resin can be phenol formaldehyde (PF) resin, urea formaldehyde (UF) resin, epoxy resin, silicone resin, melamine resin, alkyd resin, unsaturated polyester (UP) resin or polyurethane (PU) resin; whereas, the said thermosetting resin can be general-purpose plastic, engineering plastic or blended plastic. For example, the general-purpose plastic can be polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), acrylonitrile-butadiene-styrene (ABS) or polymethylmethacrylate (PMMA); the engineering plastic can be polyamide (PA, nylon), polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polymethylpentene (PMP), polycarbonate (PC) resin, polyacetal engineering polymer (POM), modified polyphenylene oxide (MPPO) resin, liquid crystal polymer (LCP), polyamide-imide (PAI), polychlorinated triphenyl (PCT), polyetheretherketone (PEEK), polyether-imide (PEI), polyethersulfone (PES), polyimide (PI), polyphenylene sulfide (PPS) or polysulfone (PFS); whereas, the blended plastic can be ABS/nylon, ABS/PVC, ABS/PC, ABS/SMA (styrene maleic anhydride), PPO (polyphenylene oxide)/PS, PPE (polyphenylene ether)/PS, ABS/polysulfone, PC/PBT, PC/PET, PC/PE, PC/ASA (acrylonitrile-styrene-acrylate), PC/PU, PC/SMA, PBT/ethylene, PET/elastomer, PET/PMMA, PET/polysulfone, PPO/PBT, nylon/ethylene, nylon/elastomer, nylon/PTFE (polytetrafluoroethylene) or PPO/nylon. On the other hand, in the aforementioned forming methods, the said filler is an organic or inorganic material, such as wood flours, cellulose pulp, a mineral material like asbestos or mica; the filler can be a powder or a long fiber, acting as an extender and sometimes also achieving an effect of reinforcement to strengthen the resin. A formula of making the aforementioned plastic can be changed by various proportions, such as using 45% of PF resin, 50% of filler and 5% of pigment. Besides, a toughening agent and a release agent which facilitates releasing the mold during formation, can be added. As being a solid under normal temperature, the resin has to be minced, put on with the pigment, added with the release and toughening agents and finally put on with the filler before completely milling. Next, the resin is let to pass through a circulating heating barrel. The adhesive agent is molten by heat to blend the filler and when exiting the barrel, the resin is in a plate shape and is made into grains after cooling; this final product is a molding powder.
The aforementioned forming methods using the plastic material to embed the heating wire can use one of the forming methods including compressing, extrusion, transferring and casting.
The aforementioned forming method using the glass fiber reinforced plastic to embed the heating wire can use stack compressing to combine an exterior of the heating wire with the glass fiber reinforced plastic for hardening, allowing the heating wire to be embedded in the glass fiber reinforced plastic.
Forming methods 1, 2 of the present invention are described hereinafter using the compressing technology.
A forming method 3 of the present invention is described hereinafter using the stack compressing technology.
In the aforementioned forming method, the said resin is a thermosetting resin which can be PF resin, UF resin, epoxy resin, silicon resin, melamine resin, alkyd resin, UP resin or PU resin.
It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
