The water outlet pipe end is equipped with line water outlet 15 and horizontally-arranged water outlet 16；The plug be installed in line water outlet or it is horizontally-arranged go out
On the mouth of a river.
The application uses closestool hydrocone type principle, on the one hand, inverted U-shaped flat siphon pipe is set in hydrocone type main body
And trap, siphon circuit design is perfectly realized in space as small as possible, can realize higher flow, when water swashs
It can accelerate draining during increasing, ensure family not by water logging；On the other hand, due to the effect of trap, can prevent from blocking sewer
Foul smell superinverse.In addition, being equipped with line water outlet and horizontally-arranged water outlet in water outlet pipe end, the adaptability of siphon floor drain is improved,
It can apply on various installation environments.
As the application preferred solution, the sluicing platform upper surface is inclined plane；Angle between inclined plane and horizontal plane
For 10-25 °；The inner walls are arc inner wall.On the one hand, the angle of inclination of sluicing platform is based on both meeting small spatial design
Increase the impact force of current at the same time, be more advantageous to draining；Another convenience, the design of arc inner wall make flowing water be pooled to water outlet automatically
At mouthful, it will not dabble.
As the application preferred solution, the water inlet pipe is obliquely installed, between the axial direction and vertical direction of water inlet pipe
Angle be 5-10 °.Siphon pipe with certain angle of inclination, more laborsaving than vertical siphon pipe, drainage effect is more powerful.
It has been investigated that when the angle a between the axial direction and vertical direction of water inlet pipe is 7 °, drainage effect is the most laborsaving and strong
Strength.
As the application preferred solution, the water seal depth L of the trap is 50mm；The water-holding quantity of trap is 220-
280ml.Siphon circuit design is perfectly realized in space as small as possible, the water seal depth L of another trap can reach state
Border standard 50mm, sufficient water seal height, greatly ensure that odor-resistant result.In addition, the water-holding quantity super large of trap, 30 days
It will not dry up.
As the application preferred solution, the longest length of vertical section of the bend pipe is 75mm, and most wide width is
20mm.The inner-walls of duct of flat siphon pipe is set for arc, and the vertical section size of bend pipe is siphon discharge area, about
1415 square millimeters, no better than the discharge area (1452 square millimeters) of diameter 50mm drainpipes, reach full packages draining.
As the application preferred solution, the plug is threadedly attached in line water outlet or horizontally-arranged water outlet；Institute
The back side for stating plug is equipped with spanner 21；Auxiliary tool is not required in the design of spanner when mounted, easier for installation.The plug
Rubber ring (not shown) is equipped between in line water outlet or horizontally-arranged water outlet；It is all provided with line water outlet and horizontally-arranged water outlet
There are drain structure, 50.8 millimeters of interface diameter, using plug-type structure, it can be achieved that full packages draining.
As the application preferred solution, the siphon floor drain further includes 3 He of grate pallet in hydrocone type main body
Grate 4 and rubbish strainer 5 on grate pallet；The grate pallet is middle empty pallet；The upper table of the middle empty pallet
Face is recessed with the limiting groove 31 for matching with grate shape；The hollow position of middle empty pallet has extended downwardly annular installation
Ring 32；The annular mounting ring inner wall is equipped with the annular mounting portion 33 for being used for installing rubbish strainer；The opening inner wall of the housing is convex
Equipped with multiple first wedge-shaped protrusions 111, the grate pallet is equipped with coordinates the second wedge shape of snap lock convex with wedge-shaped protrusion
Play 34.Grate pallet realizes simple-mounting-dismounting by the first wedge-shaped protrusion and the cooperation snap lock of the second wedge-shaped protrusion.
Specifically, multiple osculums 41 are offered on the grate, outwards week radially arranges the osculum from center；
Grate periphery is equipped with annular groove 42.The grate surrounding is low, middle high, the osculum spatially draining of grate, when hair is accumulated
When, it can be scattered in inside the annular groove of surrounding, not interfere with the water drainage of centre, reach nonclogging effect.
In addition, the application is also covered with protective cover 7 above grate, protective cover is clamped on grate support by rubber ring compression
On disk, the top of protective cover carries horizon rule, the protective cover can effectively protect hydrocone type main body and installation when not
It can do to spend grate protection cover, from handles, instrument is not required when changing grate.
The rubbish strainer, which includes tilting strainer 51 and is disposed around, to be tilted strainer periphery and prolongs side 52；Tilt strainer and level
The angle in face is 5-15 °；The inclination strainer is equipped with for the first perforate 53 of bend pipe stretching and equipped with for exchanging for
The knob 55 of rubbish strainer；The side of prolonging is on grate pallet.Tilting solid rubbish strainer, makes rubbish automatically stack exist
Low-lying place, ensures that draining is smooth.
A kind of siphon floor drain applied on washing machine of embodiment 2
As Figure 6-9, the present invention also provides a kind of siphon floor drain applied on washing machine, the specific siphon floor drain to exist
The snap-in casing 6 being arranged between grate and rubbish strainer is further included on the basis of embodiment；The snap-in casing includes
Mounting disc 61, the tube body 62 being arranged in mounting disc；The mounting disc is equipped with radial drainage holes, beneficial to draining；Mounting disc
Outer peripheral edge be convexly equipped with spacing block set 611, the grate pallet is equipped with the guide groove 35 for being used for installing spacing block set and is used for
Limit the L-shaped limiting slot 36 of spacing block set movement；The guide groove is connected with L-shaped limiting slot；The guide groove is located at hollow support
The upper surface of disk, the L-shaped limiting slot are located in annular mounting ring；The mounting disc is limited in limiting slot by spacing block set
And it is fixed on grate pallet；The second perforate 54 stretched out for tube body is offered on the rubbish strainer；The tube body is through the
Two perforates are stretched into the trap.Due to the limitation of locus, should be applied to the grate of siphon floor drain in washing machine without
Annular groove need to be set, and in flat sheet-like, the osculum on grate is parallel with the osculum in rubbish strainer, it is possible to achieve fast
Fast draining.
This applies the siphon floor drain on washing machine, and using closestool hydrocone type principle, washtub is directly or by variable
Pipe sleeve is inserted directly into the tube body of snap-in casing, the tube body insertion water seal inside, both can deodorization, prevent worm from being climbed into from drainpipe
In washing machine, meanwhile, powerful displacement also directly produces siphon effect, and the main body of bowl-type will not also produce turbulent flow, and draining is suitable,
Do not produce and dabble.
The public hydrocone type main body of the siphon floor drain of the design and the application and grate pallet, realize General design,
Reduce production cost.
The above embodiment is only the preferred embodiment of the present invention, it is impossible to the scope of protection of the invention is limited with this,
The change and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention
Claimed scope.
