Description
Technical field
The present invention relates to the technical field of drainage arrangement manufacture more particularly to a kind of floor drains.
Background technology
In daily life, floor drain is the important interface for connecting sewer pipe and indoor bathroom ground, as being arranged in house
The important component of water system, the performance quality of floor drain directly affect the quality of room air, non-to the peculiar smell control of bathroom
It is often important.
With the development of the times, requirement of the people to quality of the life is higher and higher, and traditional water seal floor drain is gradually various
New anti foul drain is replaced.
In the prior art, the Odor-returning preventing device of odour-proof floor drain is generally arranged in downcomer, is limited by downcomer caliber
Or the structure limitation of deodorization apparatus, the drainage speed of this kind of floor drain is usually relatively slow, and ground can be usually caused when user has a bath
The problem of ponding.
Currently, need the drainpipe of washing machine being inserted into floor drain in washing machine drainage, because washing machine is in draining
Displacement is big, drainage speed is fast, and existing floor drain displacement is small, drainage speed is slow, and in floor drain washing machine drainage water route
Be connected with the water route of ground sewage draining, so, be frequently present of when washing machine drainage due to floor drain impeded drainage and
The problem of water being returned to bathroom ground.
In the house type of China city dweller, the ventilation of most bathrooms is unsmooth, and excess surface water or washing machine return water and be easy
Cause bathroom ground humidity, bacteria breed, air dirt problem, to cause harmful effect to the quality of the life of resident.
Floor drain earthward returns water when in order to solve the problems, such as washing machine drainage, has one kind to prevent washing machine from arranging in the prior art
The floor drain of water is returned when water, technical solution is that the water route for draining ground sewage in the floor drain is cancelled, and water is not returned to reach
Effect.But its problem is that ground sewage can not be discharged for this floor drain, needs user to be in addition arranged and is arranged for ground sewage
The floor drain of water increases the decoration cost of user and the complexity of construction.
To solve the above-mentioned problems, there is an urgent need to one kind on the basis of odor-resistant result is good by people, realize that displacement is big, row
Water speed is fast, and the function of washing machine drainage and land drainage can simultaneously be realized on a floor drain, and not when doing washing draining
Earthward return the floor drain of water.
Invention content

Compared with prior art, beneficial effects of the present invention are：
(1) Odor-returning preventing device of existing floor drain is arranged mostly in the inside of downcomer, is limited by the space of downcomer diameter
Cause displacement small, people have a bath when often will appear excess surface water the problem of.Floor drain provided by the invention, Odor-returning preventing is filled
It installs in the top or side of downcomer, i.e., the first drip chamber and the second drip chamber is set in the top of downcomer or side,
Mono-directional drainage is installed at drip chamber connector simultaneously, ground sewage is by the mono-directional drainage by the first draining
Room unidirectionally flows into second row hydroecium, through downcomer interface is discharged into downcomer, first drip chamber, the second drip chamber and list again
It to drainage arrangement not in downcomer, is not limited by the space of downcomer diameter, the drainage space with bigger can carry for user
For the displacement of bigger, to effectively reduce the generation of ground area water problems.
(2) existing floor drain often will appear the problem of returning water when slotting washing machine sewer pipe drains, because in floor drain
The water route of washing machine drainage is connected with the water route that ground sewage drains, floor drain provided by the invention, in the water of washing machine drainage
It is provided with mono-directional drainage between road and the water route of ground sewage draining, to ensure that washing machine will not be earthward in draining
Return water.The present invention realizes on same floor drain, under the premise of ensureing not return water while having washing machine drainage and ground dirty
The function of water draining.
(3) floor drain provided by the invention, the quantity that washing machine drainage mouth is arranged on floor drain panel is without limitations, can be simultaneously
More than one washing machine sewer pipe is connected, to facilitate user to connect more washing machines while use.With people's life water
The relieving of flat raising and two tire policies, much families all buy two or more washing machines now, are convenient for the clothing of child adult
It separately washes or underwear and coat is separately washed, release of the invention keeps user's draining when using more washing machines more convenient.
(4) existing floor drain is only seen by detachably under-enumeration, can just be checked when bathroom sewer occurs and returns taste
Floor drain whether bad sealing, floor drain provided by the invention, in this case, user can directly can be understood by observation window
Whether the encapsulation situations of the water fender are checked on ground, tight-closed to easily understand floor drain.When water blocking plate closing is not tight,
The mark line of water fender lower end position and observation window can be misaligned, this design can avoid user and check floor drain by dismounting.
(5) dirt of existing floor drain would generally deposit at Odor-returning preventing device, and when cleaning is cumbersome, provided by the invention
Anti-blocking dirt hand basket is arranged in floor drain before mono-directional drainage, before can dirt being blocked in mono-directional drainage, can subtract
The possibility that few floor drain blocks, and clear up dirt convenient for user.Hand basket, which is promoted, using the mating handle of the hand basket topples over dirt,
The work of cleaning floor drain can be completed in the case where not making hand dirty by user.This design can avoid user and be cleared up by dismounting
Floor drain.
(6) when the new building in China residential houses is delivered now, toilet is sunk type mostly, in sunk type bathroom ground
Drainage pipeline needs user to be voluntarily laid with, and when being laid with drainage pipeline, common floor drain needs will prolong under the laying of bathroom ground
Pipeline could connect installation after curving upwards, there are two problems for this mounting means, first, construction bothers, second is that turning is easy
It blocks, and once blocks and be difficult to clear up.For this case, the present invention, which provides, a kind of downcomer interface to be arranged on the ground of side
Leakage, design is advantageous in that in this way, can be connected directly between on floor drain first, downcomer does not have to bending, reduce the complexity of construction
Degree, second is that once occurring to block convenient for dredging cleaning.
