Provides effective protection against electrical hazards by grounding the bathtub, ensuring immediate power interruption and user safety.
Abstract
Description
** Technical Field: **The present invention relates to an innovative drain fitting for bathtubs made of electrically conductive plastic or conductive material, such as stainless steel or galvanized steel. This construction enables secure grounding of the bathtub and provides additional protection from electrical fault currents.**Hintergrund of the Invention: **In modern bathrooms, bathtubs made of non-electrically conductive materials such as acrylic or plastic are frequently used. These materials, while providing pleasing utility, lack the ability to dissipate electrical currents. In the event of an electrical fault, such as the accidental contact of an electrical appliance (e.g. fowl) with water, this may lead to dangerous situations. The present invention aims to minimize this risk and to ensure effective personal protection.**Technical solution: **The drain fitting comprises the following features: 1. **Materialselection: ** The fitting consists of an electrically conductive plastic, such as, for example, polypropylene with conductive additives, or of a conductive metal, such as stainless steel or aluminum. These materials ensure reliable electrical conductivity and corrosion resistance. 2. **Erdungs connection: ** A special connection is integrated on the drain fitting, which makes it possible to connect a ground line. This connection is designed to establish a secure connection for grounding the water in the bathtub. 3. **WaterContact:** Since the drainset is in direct contact with the water, the water in the bathtub is grounded. This means that in the event of an electrical fault, the fault current is derived via the ground. 4. ** Protection mechanism: ** In the event of a fault, such as the penetration of an electrical device into the water, the earth terminal activates the residual current circuit breaker (RCD) or the line circuit breaker. This leads to an immediate interruption of the power supply and thus protects the users from electric impacts. 5. **Einfache installation: ** The drain set is designed to be easily and quickly incorporated into existing bathtub installations. The grounding terminal can be easily connected to the existing grounding of the house.**:****Erhöhter Personal Protection: ** The combination of conductive material and ground terminal offers effective protection against electrical hazards in bathrooms.** Compatibility:** The clothing can be installed in various bathtub models, regardless of the material used.**Nach: ** The use of long-lived and corrosion-resistant materials increases the life of the drain fitting.**:**This innovative drain fitting for bathtubs represents an important improvement in the field of safety technology. The possibility of grounding significantly increases the protection of users in bathrooms which consist of non-electrically conductive materials. This invention makes a substantial contribution to safety in modern bathrooms.
Claims
** Drain set for bathtub** made of electrically conductive material, said material being selected from the group consisting of conductive polypropylene, conductive polyethylene, conductive PBT or metal, and having a terminal for a ground line.** Drain set according to claim 1 **, wherein the drain set is designed to be in contact with the water in the bathtub in order to guarantee that the water is grounded.** Drain set according to Claim 1 or 2 **, in which the ground line is designed to activate the fault current circuit breaker (RCD) or the line circuit breaker in the event of an electrical fault, in order to prevent an electrical shock.** Drain set according to any one of the preceding claims** designed to be integrated in existing bathtub installations without requiring extensive modifications.
