Reverse siphoning type great-discharge-volume floor drain

Abstract

The invention provides a reverse siphoning type great-discharge-volume floor drain, which comprises a case and a sealing cover, wherein the sealing cover is covered above the case so as to form a cavity; a siphoning assembly is arranged in the cavity, and comprises a water sealing core and an inner core; an opening of the water sealing core is upward and is arranged inside the cavity; the inner core is in a tubular shape with openings at two ends and is arranged inside the water sealing core; a flanging edge outwards extends from the upper edge of the inner core; the flanging edge is in abut joint with the inner wall of the case; the bottom of the water sealing core is provided with a flow guide table; the flow guide table upwards projects and extends. A plurality of water discharging passages are formed among the water sealing core, the inner core and the case; the cross area of each passage is smaller than the cross area of the upper passage. The plurality of water discharge passagesare formed; the cross section ratio of the two adjacent passages are controlled; the siphoning water discharging effect is good; the water discharging quantity is great.

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 ...

Problems solved by technology

[0003] In the traditional technology, the additional suction force in the form of siphon 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 setting of the three drainage channels is not easy to make the air in the drainage channel Completely discharged, the siphon drainage effect is not good, the water leakage speed of the floor leakage is slow, and the drainage volume is small
