Description

The invention relates to a hygienic handwashing basin comprising a basin-shaped base body with a low point and a drain extending from the low point of the base body, wherein the drain can be connected to a wastewater pipe. Germs, such as bacteria, are present in the drain and wastewater pipe. In hygiene handwashing basins, such as those used in hospitals, it is important to prevent these germs from leaving the drain and entering the basin's main body. Consequently, it is necessary to prevent water from splashing back out of the drain. Washbasins of this type for rooms with increased hygiene requirements are, for example, known from DE 20 2021 105 102 U1 and DE 10 2021 117 601 A1. The content of these applications, in particular regarding feasibility and possible designs, is incorporated into this application. The object of the invention is to create a hygienic handwashing basin and a handwashing workstation with at least one hygienic handwashing basin that meets the highest hygiene standards in an alternative way. This problem is solved by the subject matter of the independent claims. According to the invention, the hygiene handwashing basin is designed and / or can be used, for example, in rooms with increased hygiene requirements, e.g., in hospitals, clinics, medical practices and / or nursing homes. The hygiene handwashing basin has a basin-shaped base with a low point. Preferably, the base body has a bottom wall and a surrounding basin wall. The base body and the bottom wall can preferably be formed in one piece. The basic body can, for example, be rectangular with four basin wall segments and one base segment. For example, the base can be between 20 cm and 50 cm wide, e.g., 40 cm. The depth of the base can be between 20 cm and 50 cm, e.g., 30 cm. The height of the base can be between 5 cm and 30 cm, e.g., 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, 11 cm, 12 cm, 13 cm, 14 cm, 15 cm, 16 cm, 17 cm, 18 cm, 19 cm, 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, or 25 cm. Alternatively, the basic shape can be round, semicircular or oval, for example. For example, a round base can have a radius between 10 cm and 25 cm, e.g., 15 cm, 16 cm, 17 cm, 18 cm, 19 cm, 20 cm, or 25 cm. The height of the base can, for example, be between 5 cm and 30 cm, e.g., 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, 11 cm, 12 cm, 13 cm, 14 cm, 15 cm, 16 cm, 17 cm, 18 cm, 19 cm, 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, or 25 cm. For a semicircular or oval base body, the maximum width can preferably be greater than the maximum depth. For example, a semicircular or oval base can have a maximum width between 20 cm and 50 cm, e.g., 40 cm, 41 cm, 42 cm, 43 cm, 44 cm, or 45 cm. The maximum depth of the base can be, for example, between 20 cm and 40 cm, e.g., 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, or 35 cm. The height of the base can be, for example, between 5 cm and 30 cm, e.g., 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, 11 cm, 12 cm, 13 cm, 14 cm, 15 cm, 16 cm, 17 cm, 18 cm, 19 cm, 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, or 25 cm. The material thickness of the base body can be, for example, between 0.5 mm and 15 mm. For a metal base body, the material thickness can be, for example, between 0.5 mm and 1.2 mm, e.g., 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, or 1.1 mm. For a base body made of a mineral material, the material thickness can preferably be between 5 mm and 15 mm, e.g., 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, or 14 mm. The hygiene handwashing basin has a drain extending from the lowest point of the base, and the drain can be connected to a wastewater pipe. The drain may preferably have at least a section with an external or internal thread for attaching the wastewater pipe. Preferably, the drain and / or the wastewater pipe has a circular cross-sectional area. The diameter can be, for example, between 3 cm and 5 cm, e.g., 4 cm or 4.5 cm. Alternatively, the drain and / or wastewater pipe can have an oval, semicircular, slit-shaped, slot-shaped, and / or rectangular cross-sectional area. For example, the height can be less than the width. For example, the opening of the drain can have a height between 1 cm and 3 cm, e.g., 1.5 cm or 2 cm. The width can be between 3 cm and 5 cm, e.g., 4 cm or 4.5 cm. The cross-sectional area of ​​the drain and / or wastewater pipe is preferably constant and / or uniform. Alternatively, it is variable and changes. Preferably, the wastewater pipe is cylindrical and / or tubular in shape. For example, the drain does not extend across the entire width of the base body, i.e., it is smaller than the width of the base body. Preferably, the drain is arranged centrally with respect to one side of the base body. Preferably, the width of the drain is a maximum of 50%, 40%, 30%, 25%, 20%, 15%, or 10% of the width of the base body. For example, the width of the base body is a maximum of, or exactly, 20 cm, 15 cm, 10 cm, 9 cm, 8 cm, 7 cm, 6 cm, 5 cm, 4.5 cm, or 4 cm. The height of the drain opening can be between 1 cm and 5 cm, e.g. 1.5 cm, 2 cm, 3 cm, 4 cm or 4.5 cm. The bottom of the drain has a downward curve immediately from the lowest point of the base body. The bottom of the drain is the area where the water initially flows away. Even if this area becomes a ceiling due to a bend in the drain's path, or merely serves as a lateral boundary in a vertical section, the term "bottom" is still used to describe the rest of the drain's length. Therefore, the bottom is the inner or lower section of the drain that originally carries the water, and any extension thereof. The curvature can be convex and / or concave. For example, the curvature has at least or exactly one arc. For example, several arches may be provided. The arches may be arranged in a labyrinthine pattern. Because the bottom of the drain has a downward curve immediately from the lowest point of the base, it is prevented that draining water splashes back along with germs originating from the sewage pipe. It was surprising that backflow is prevented not only with a straight, downward-sloping drain but also with a curved one. The highest hygiene standards are thus met. Further developments of the invention can also be found in the dependent claims, the description and the accompanying drawings. According to one embodiment, a vertical section of the drain or wastewater pipe follows the curve. The curve is designed such that, when viewed from above along a vertical axis of the vertical section, a maximum of 50%, 40%, 30%, 20%, 10%, 5%, 4%, 3%, 2%, or 1% of the cross-sectional area is visible. The vertical axis of the vertical section is any vertical axis that lies section by section within the cross-sectional area of ​​the vertical section. The entirety of the vertical axes forms, as it were, a virtual extension of the vertical section. In other words, if a user looks down into the drain opening, they will see at most 50%, 40%, 30%, 20%, 10%, 5%, 4%, 3%, 2%, or 1% of the cross-sectional area of ​​the vertical section. At least a large portion of the section is obscured. The vertical section can, for example, be cylindrical and / or tubular and / or have an external or internal thread. In a further embodiment, a vertical section of the drain or wastewater pipe follows the curve. The curve is designed such that the cross-sectional area of ​​the vertical section is not visible when viewed from above along a vertical axis of the vertical section. The vertical axis of the vertical section is any vertical axis that lies section by section within the cross-sectional area of ​​the vertical section. The entirety of the vertical axes forms, as it were, a virtual extension of the vertical section. In other words, if a user looks down into the drain opening, they cannot see the vertical section. That section is completely hidden. If the user were to insert a straight rod vertically into the visible opening of the drain, it would not hit the cross-sectional area of ​​the vertical section, since either access through the wall of the base body or the wall of the drain would not be possible and / or the curvature would prevent this. The vertical section can, for example, be cylindrical and / or tubular and / or have an external or internal thread. According to another embodiment, the angle of curvature is at least 60°. For example, the angle of curvature can be at least or exactly 60°, 70°, 80°, 90° or more. The drain is therefore relatively strongly curved, effectively preventing backflow and making it virtually impossible for germs to rise to the top. According to another embodiment, the base body has or consists of a metal material, preferably steel, e.g. stainless steel. The basic body can, for example, be rectangular with four basin wall segments and one base segment. Alternatively, round, semicircular or oval shapes are also conceivable. The pool wall segments and the bottom segment can be molded in one piece or welded together. For example, the opening of the drain can border a pool wall, preferably at the rear, and / or extend at least partially into it. The drain can be connected to the wastewater pipe, which is preferably located next to the base body. According to another embodiment, the drain is designed as a pipe that is welded to the base body. It was surprising that it is even technically possible to weld a curved pipe directly at the lowest point of the base body. Alternatively, the pipe can also be formed in one piece with the base body during manufacturing. In both cases, the pipe is permanently attached to the base. According to another embodiment, the base body has or consists of a mineral material. For example, the mineral material may contain or consist of aluminium hydroxide, a polyester resin and / or an acrylic resin. Preferably, the base body is round, semicircular or oval. Alternatively, a rectangular shape is also conceivable, for example. Preferably, the base body has a flat upper edge. The edge can be, for example, between 1 cm and 5 cm wide, e.g., 4 cm. Preferably, the edge forms a flat, horizontal surface. The edge is purely optional and can also be omitted. The entire base body is preferably formed in one piece. The pelvic wall and the pelvic floor can merge into one another in this process. For example, the drain opening can be spaced away from the pool walls. The drain can be connected to the wastewater pipe, which is preferably located below the base. The wastewater pipe is preferably connectable to a flat and / or horizontal connection surface on the underside of the base body. For example, a thread and / or a seal may be provided for this purpose. According to another embodiment, the passage is a feedthrough that extends through the mineral material. For example, the penetration extends from the lowest point of the base body to a flat connection surface for the wastewater pipe. The opening can preferably be created in the mineral material by a cutting and / or machining process, e.g., cutting, turning, drilling, milling and / or grinding. Alternatively, the opening can be punched, blasted and / or laser-etched. It was surprising that it was even technically possible to incorporate a curved feedthrough into the mineral material. Alternatively, the basic body can already have the opening incorporated during manufacturing. For example, the basic body including the opening can be created using 3D printing. According to another embodiment, a sieve is provided which can be detachably inserted into an opening of the drain. The sieve prevents objects from entering the drain, which could potentially lead to blockages. The sieve is preferably removable, so that the sieve and / or the drain can be easily cleaned. For example, the sieve can have two tongues arranged on opposite sides, preferably extending diagonally outwards. The tongues allow the sieve to be clamped, for example, to opposite inner walls of the drain. Finally, the invention relates to a handwashing workstation with at least one hygiene handwashing basin according to the invention. For example, the hygiene handwashing basin can be integrated into a worktop of a handwashing workstation. All aspects, embodiments, and features of the invention described herein can be combined with one another, preferably also independently of the specific embodiment in which they are mentioned. Preferably, all subject matter of the dependent claims can be combined with each other and with any subject matter of the independent claims. It is generally noted that terms like "ein" (a) and "eine" (a / an) do not necessarily mean "exactly one" or "exactly one," although this is also possible. The terms "ein" and "eine" can therefore be understood as "at least one" or "exactly one." The use of the singular preferably includes the possibility of the components being plural, and vice versa. It is noted that "vorzugsweise" and "bevorzugt" can be translated as "preferably" in English. A feature introduced by "vorzugsweise" or "bevorzugt" is purely optional, can be omitted, and does not constitute a limitation, for example, of claims. The invention is described below by way of example with reference to the drawings.

Thus, the same reference numerals are used for identical or comparable components in the figures and are not explained again. Fig. 1 shows a hygienic handwashing basin with a basin-shaped base 10, for example made of stainless steel. The base 10 has a low point 12 where the water collects and / or drains away. The basic body 10 is rectangular in shape and has four pelvic wall segments 14 and one bottom segment 16. A sieve 18 is arranged in an opening of a drain 20 shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. 7. The process 20 exhibits a downward curvature 22 immediately from the lowest point 12 of the base body 10. The drain 20 is connected to a vertically oriented wastewater pipe 24, which in this embodiment is located next to the base body 10. As shown in Figures 6 and 7, the sieve 18 can be clamped in the outlet 20 by one or two tongues 28. The tongues 28 can be arranged on opposite sides and / or extend obliquely outwards. The sieve 18 can preferably be removed without tools for cleaning purposes. Water can flow out at the lowest point 12 through the sieve 18 onto the bottom 30 of the drain 20. The two outermost vertical axes 32 of a vertical section 34 of the process 20 were drawn with dashed lines. The curvature 22 is designed such that a cross-sectional area of ​​the vertical section 34 is not visible when viewed from above along one of the vertical axes 32 of the vertical section 34. Figs. 8, 9, 10 to 11 each show a hygiene handwashing basin with a basin-shaped, round base body 10, for example made of a mineral material. The basic body 10 optionally has a wide rim 35. The outlet 20 leads into a vertically oriented wastewater pipe 24, which in this embodiment is located below the base body 10. As shown in Fig. 10 and Fig. 11, the drain 20 is designed as a curved feedthrough that extends through the mineral material. The wastewater pipe 24 is flanged to a flat and horizontal connection surface 36 on an underside of the base body 10. The curvature 22 of the base 30 is designed such that a cross-sectional area of ​​the vertical section 34 of the wastewater pipe 24 is not visible when viewed from above along one of the vertical axes 32 of the vertical section 34. The risk of splashing water is avoided. Thus, the highest hygiene standards are met.
