Abstract

PURPOSE: A toilet bowl ventilating device is provided which is entirely contained within a toilet seat of standard dimensions which immediately vents to the outside noxious human elimination odors. CONSTITUTION: The toilet seat(1) contains a posterior portal vent(3) that is positioned adjacent to an identical sized vent in the lateral tube, all of which are fastened to the toilet bowl by means of the standard bolts. The lateral tube connects to an elbow, on either side, with the opposite side being capped off, which then connects to a pipe(12) which enters behind the wall, which in turn connects to an air duct channel behind the bathroom wall and connecting to the exhaust fan that expels the odors to the outside. The underside of the toilet seat has a circular gasket(19) of soft rubber that forms a perfect air seal when weight is applied, thus forming a perfect air seal.

Description

Modular toilet seat ventilated to the outside {EXTERNALLY VENTED MODULAR TOILET SEAT}

TECHNICAL FIELD The present invention relates to a toilet ventilation system, and more particularly, to a toilet ventilation system in which an entire apparatus is provided in a toilet itself designed before.

Toilet seat ventilation systems are known in the art, but these models are large and inconvenient and currently difficult to retro-fit to the toilet, and further include electrical or mechanical components located next to or adjacent to the toilet so that water may overflow or splash. Potential risks may arise in cases or in the case of misuse or abuse by young children. The following conventional models listed below combine attachment clips and units in need of modification to the toilet or toilet, and are inconvenient and difficult for ordinary landlords to install and maintain, and also present electrical hazards.

Standard residential restrooms have ventilation fans on the ceiling to vent indoor gases and air to the outside. This is very inefficient because, as suggested in the power specification, the odor must first spread throughout the room and then slowly to the outside.

In accordance with a first aspect of the invention, a toilet ventilation system is provided that is self-contained in a non-empty toilet seat, the main outlet being located immediately adjacent the rear (back) end, the anus causing the unpleasant odor, which outlet is While the odor is in the toilet itself, it picks up the odor between the water pipe and the human body. Complete air sealing by the rubber gasket ensures maximum odor removal without openings. As you sit on the toilet seat, air can flow between your thighs. The manual switch that activates the fan turns on when a person enters the bathroom and turns off when exiting.

Globally, water conservation is of greater concern. Some countries have already established the maximum volume of water used to flush them once. Such a system can satisfactorily remove solids and liquid feces while using less water and greater hydraulic pressure. However, for gaseous excrement this is useless. When it comes to removing these odors, it is common sense that people will flush three or more times to remove uncomfortable odors. The present invention addresses the final element of the problem of removing human feces without having to flush water repeatedly.

In addition to providing full air tightness under the toilet seat, rubber gaskets also provide more comfort without additional cleaning or maintenance.

In general, the removal of unpleasant and harmful odors is best done by releasing these odors to the outside. Recirculating odors and spraying them inside is just the next best thing. Exhaust through an external window or through a plumbing system air outlet under the floor is too cumbersome and unnecessary. A standard toilet fan is sufficient to release the odor if the size of the air conduit and main opening ensures maximum return of air flow without the need to use the enormous suction power of Qingdao which would be annoying and uncomfortable. By arranging the main outlet immediately adjacent to the point where the odor begins, with a complete air tight seal under the toilet seat, this odor can be safely, efficiently and quickly removed by the present invention. The side tube, which is in a fixed position and whose outlet is completely parallel to the main outlet of the toilet seat, prevents water and other splashing material from entering the air channel when the seat is in the up position. The rubber gaskets below provide complete air tightness, as well as more comfort than those used in standard toilet seats. Drain plugs with wall pipes allow for regular cleaning to drain any moisture or concentrate that collects. Side tubes allow for reconditioning for left- or right-handed toilets. Either end of the side tube may be connected with an elbow that is connected to the wall pipe and the other may be covered with a lid.

The present apparatus will be described with reference to FIGS. 1 to 5.

Referring to FIG. 1, the independent toilet seat ventilator has all five parts: the toilet seat lid (2), the non-empty toilet seat itself (1), the fixed side tube (7), two mounting brackets or clips (4) and two fixing bolts (5).

Referring to FIG. 2, FIG. 2 is a bottom view of the device in the down (sitting) position, with the side tube 7 (see FIG. 4A) fixed by the main outlet 8 (not shown) in the tube. And then into the left handed connection elbow 10, the other end showing the lid 11, the main outlet 3. The mounting clip 4 holds the side tubes in place and allows the toilet seat to pivot up and down. The wall pipe 12 is connected from the elbow to the wall behind the toilet and into a nipple 14 (see FIG. 5) mounted on the wall, and a drain valve 13 (FIG. 5) in consideration of the discharge of the concentrated substance or liquid (FIG. 5). Is also provided. The rubber gasket 19 is permanently mounted in the recessed groove 20 of the toilet seat and operates without maintenance, creating a complete air seal between the toilet seat and the bottom of the toilet seat.

Referring to FIG. 3 (wire diagram), a rubber gasket 19 (see FIG. 2) surrounding the bottom surface of the toilet seat is installed in the recessed groove 20. The main outlet 3 inside the non-empty material of the toilet seat is adjacent to the cause of the odor generated in the toilet bowl. This forms a short, compact air channel, where the inhalation of air from the ceiling-mounted fan 16 (see FIG. 5) immediately follows the scent that fills the toilet's cavities and enters the room immediately after the odor has occurred. Soak up the smell The main outlet of the fixed side tube 7 (see FIG. 4A) is located exactly opposite the main outlet 3 of the toilet seat which allows air to flow into the fixed side tube 7.

Referring to FIG. 4A, this cross section shows the toilet seat in the down (sitting) position. The rubber gasket 19 forms a complete air seal. A splash guard 6 is at the top of the toilet. The main outlet 3 of the toilet seat and the main outlet 8 of the side tube 7 are in a row and form an open air flow channel.

Referring to FIG. 4B, this cross-sectional view shows the toilet seat in the up position. The toilet seat is now in the raised position, and the splash guard prevents water overflow or splashing from entering the air flow channels, ie the side tubes. The side tubes form an inner sleeve in the clip attached to the toilet seat itself, so that the main outlet 3 of the toilet seat and the main outlet 8 of the side tube are no longer aligned, and water It cannot enter the side tube. The small space between the side tube and the toilet seat allows some air to flow in order not to overpress the ventilation fan.

Referring to FIG. 5, this shows a complete device once attached to the wall pipe and ultimately attached to the transport behind the wall. The complete air flow channel begins in the toilet space, and ascends through the main outlet of the toilet seat, enters the side tube (7), enters the wall pipe, rises above the conduit, and ultimately exits the outside atmosphere.

The operation of this device is very easy and simple. When you go to the bathroom, switch it on to activate the ventilation fans on the ceiling. The airflow channel opens when the toilet seat is in the down position, and immediately after excretion a toxic odor is released to the outside before this odor fills the space in the toilet. The space between the human thighs forms an air inlet, and the main outlet of the toilet seat is an external flow. The space forms a sufficient opening to allow for the continued flow of air. Even if a large adult blocks the space, the air above the surface of the toilet prevents the creation of a vacuum. Since the odor is removed immediately after production, the suction power of the system can be kept to a minimum of the specification, and the standard discharge outlet fan can quickly remove all odors.

When you have finished looking at the toilet, flush the toilet. When the toilet seat is raised to the up position, the airflow channel is blocked, thereby preventing the toilet from overflowing or bouncing and preventing the ingress of water which may result from a child's misuse or breakage of the device. Cleaning and maintenance are minimally necessary. The bottom can be washed with household cleaners and bleach. The drain valve on the wall is for discharging the concentrated concentrate.

The present invention provides a toilet ventilation device that is completely included in a toilet seat of a standard size that immediately discharges the toxic odor of human waste to the outside without having to repeatedly flush the water, thereby effectively discharging the toxic odor of excreta. It can comfortably resolve the stool, save water by not having to flush several times to release toxic odors, and prevent water from entering the side tubes by blocking the air flow channel when raising the toilet seat It has an effect that can be done.
