Floor drain

Abstract

Floor drain with water trap including an upper screen (19, 28) or lip and a lower screen or threshold (32, 36) extending to a higher level than the lower edge of the upper screen, and that the water first flow below the upper screen and thereafter over the lower screen. The inlet part before the upper screen has a small cross-section or volume in relation to the water volume between the upper andthe lower screen securing an efficient flushing away of light pollutions.

Description

technical field [0001] The present invention relates to closed floor outlets or floor drains and water seals or water traps for floor outlets or floor drains for bathrooms, toilets, kitchens and the like. Background technique [0002] An unsatisfactory problem with floor drains is the cleanliness of the floor drain itself. If the drain is not kept clean, the risk is that organic matter accumulates in the drain, where it rots and emits an odor. Deposits can also occur in floor drains, causing them to clog. Removal and cleaning by chemical means needs to be performed frequently. Possibility of cleanup is made difficult by the water trap and the accumulation of organic pollutants is thereby enhanced. [0003] Water traps are used in floor drains to prevent air and odors from the sewer system from entering living spaces. In the water trap (odor seal), the outgoing water is forced to flow first under the first strainer and then over the second strainer, the upper edge of whic...
