Abstract

The utility model relates to a negative pressure integral toilet bowl with wind extraction. The utility model can directly discharge the stench of urine and excrement into a sewage along a flushing hole [23], a pipeline [19] which leads to a urinal and a blower fan below a water tank, an exhaust elbow pipe [14], a connecting hose [30], the blower fan [18] hidden below the water tank and an exhaust outlet [25] in the urinal of the negative pressure integral toilet bowl and can thoroughly replace a scavenger fan and an exhaust passage. The utility model relieves the trouble of the installation of the scavenger fan, saves space, makes the stench of urine and excrement not get out of the urinal at all, and thoroughly solves the problem that the stench of urine and excrement passes before a face, disperses into a toilet and is discharged out by the scavenger fan.

Description

The whole water closet of negative pressure

The utility model relates to the whole water closet of a kind of negative pressure with exhausting.

Water closet in the market, or high level cistern or low level cistern, or split type or Contiuum type be not all with the function of exhausting.Do not find the water closet of band extractor fan on the net from patent information yet.During excrements, the foul smell of excrements is diffused into the washroom, and outdoor by the ventilation fan discharge of washroom again, this is present ubiquitous situation, and in this process, unavoidable a part of foul smell enters nasal cavity, exists some inconvenience really.

Task of the present utility model provides the whole water closet of negative pressure a kind of simple in structure, with low cost.It can make the excrements foul smell not go out the toilet seat pond at all, directly enters sewer pipe along the bath path through blower fan, is discharged to roof along main sewer again.

The whole water closet of negative pressure of the present utility model is at volume, be as good as substantially with present whole water closet in appearance, and inside has increased extractor fan, can make and produce negative pressure in the urinal, allow foul smell enter sewer pipe along the negative pressure direction, be discharged to roof along main sewer again, and solved all technical barriers of realizing exhausting.At first, solved the backwater problem.Use the bath path to carry out exhausting, and must not allow water enter blower fan, the exhaust elbow in the water tank and on spillway hole solved this problem.Exhaust elbow is higher than the water surface in the water tank, even exhaust elbow is communicated with water tank, the also high only bend pipe of water surface top, guarantee that water advances less than blower fan, spillway hole on the exhaust elbow is a little more than the water surface, if the malfunctioning water surface of ball valve raises, then unnecessary water flows directly into urinal along spillway hole, makes water not advance blower fan at all.The power 15w--25w of blower fan.Secondly, solved the return-air problem.Be provided with return air valve at fan outlet, when having return-air to produce in the sewer pipe, valve closing stops return-air; When blower fan was worked, valve was blown open, realized ventilation.The 3rd, solved the outage problem that discharges water.The cut-off button that discharges water, energising at ordinary times, and outage when discharging water, button has spring, and button one side is provided with start stop lever, during button pressed downwards, length of spring compressed, start stop lever disconnecting circuit, blower fan stall, open in the bath hole of water tank bottom, realizes bath, during the button pop into position, the bath bore closure, bath stops, and start stop lever is connected circuit, blower fan work.So both can guarantee safety, can reach the water saving purpose by discharge time length control discharging quantity of water again.The coefficient of elasticity of spring is preferably 1kg/cm.The 4th, solved the air quantity size issue.The place ahead at the whole water closet of negative pressure is provided with the negative pressure speed-regulating switch, can be according to different needs regulated at will air quantity, and when air quantity is maximum, can make whole washroom realize ventilation.The circuit hole is reserved in the toilet seat pool side edge, and the switch groove is reserved in negative pressure speed-regulating switch position.The whole water closet of negative pressure, also malfunctioning to the ball float in the water tank and problem that water outlet of water tank leaks is provided with spillway hole and observes with convenient, under the normal condition, water tank is water-tight, leaks during as if low water stage, certainly for water outlet of water tank leaks, should in time change skin plug and skin plug ring; If low water stage is water-tight, and high water level leaks, and is due to water overflows from the spillway hole on the exhaust elbow, then for ball float has problem, should in time overhaul ball float.

Because this utility model has been carried out perfect combination with exhaust and toilet seat, greatly facilitates the user, saved and cut a piece of glass the troublesome work of dress exhaust fan; Especially the washroom is located at the middle structure of building body, has saved ad hoc ventilation stack, saved area, reduced cost; More outstanding effect is that foul smell is spread less than the washroom at all, has solved the air quality problems of washroom up hill and dale.
