Reverse siphoning type great-discharge-volume floor drain

Abstract

The invention provides a reverse siphon type large displacement floor drain, which comprises a shell and a cover, the cover is closed above the shell to form a cavity; a siphon component is arranged in the cavity. The siphon assembly includes a water-sealing core and an inner core, the water-sealing core opens upwards and is set inside the cavity; the inner core is cylindrical with two ends open and is set inside the water-sealing core ; The upper edge of the inner core extends outwards with a folded edge, and the folded edge is in contact with the inner wall of the outer shell, and the bottom of the water sealing core is provided with a deflector, and the deflector protrudes upwards stretch. A plurality of drainage channels are formed between the water sealing core, the inner core and the outer shell, and the cross-sectional area of ​​each channel is smaller than that of the previous channel. The invention forms a plurality of drainage channels, controls the cross-sectional area ratio of two adjacent channels, and has good siphon drainage effect and large drainage volume.

Description

Technical field [0001] The invention relates to a floor drain, in particular to a reverse siphon type floor drain with large displacement. Background technique [0002] The bathroom of a family or hotel is a place where people use to take a bath. The water consumption during bathing is generally large. The water that falls to the ground, because the sewer is in a recessed position on the ground, the bathing water will naturally flow to the entrance of the sewer, due to the inconvenience of the sewer directly It is the same as the bathroom, so it is necessary to install a floor drain device at the sewer. [0003] In the traditional technology, the additional suction force of the siphon form is used in the floor drain to complete the clean drainage function, but the siphon channel in the floor drain is mostly connected by three drainage channels, and the arrangement of the three drainage channels is not easy to make the air in the drainage channel Complete drainage makes the siphon ...
