  Hereinafter, specific examples of the present invention will be described with reference to the accompanying drawings.

  As shown in FIGS. 1 and 2a-2d, the toilet (10) comprises a toilet (12) in the form of a ventilation fan (14) and a duct (16) connected to the toilet via an odor outlet (20) and An odor discharging device (13) is provided. The toilet bowl (12) includes one washing water inlet (18) and two odor outlets (20). The odor outlet (20) is accommodated in the upper rim (22) of the toilet (12). The toilet (12) is an integral mold unit. However, the toilet bowl (12) can also be manufactured from a suitable number of parts, molded or not molded.

  As best shown in FIG. 2b, each odor outlet (20) is coupled to an odor outlet (13), at least a portion of each outlet (20) being a flush water inlet (18) of the toilet (12). ) It is provided at a higher position. In other words, the height from the bottom surface of the toilet (12) is higher than that of the inlet (18) at the position where each outlet (20) and the washing water inlet (18) are opened in the toilet (12). At least a portion of each outlet (20) is higher. This difference in height is illustrated in FIG. 1 where the height A of the outlet (20) is greater than the height B. Actually, it is preferable that the entire discharge port (20) is located higher than the introduction port (18) in the toilet bowl (12). The odor discharge device (13) is connected to the toilet (12) in parallel.

  The toilet (10) is joined in a normal manner to the flush water inlet (18) of the toilet (12) so that the toilet (12) can be washed and its contents removed through the waste outlet (26). A water tank (24) to be used may be further provided.

  The device (10) further includes a switch (not shown) that is operated by a user to activate the ventilation fan (14). Each ventilation fan (14) includes a timer for stopping the fan (14) after a predetermined time has elapsed after the fan (14) is operated. Alternatively, the ventilation fan (14) may be activated by a cleaning action or may be activated by a person entering a closed space with the toilet (10).

  Next, with particular reference to FIGS. 2a-2d, it can be seen that the flush water inlet (18) is at the central rear of the toilet bowl (12). The toilet bowl (12) includes a washing water channel (30) provided inside the rim (22), and allows water to pass through an inlet (18) around the toilet bowl (12). Not only is at least a part of each outlet (20) positioned higher than the washing water inlet (18), but the two outlets (20) are also spaced laterally from each other, 12) Located at the rear.

  The discharge port (20) includes a discharge path (28) connecting the discharge port (20) and the toilet bowl (12). The discharge channel (28) opens into the toilet (12) where the height from the bottom surface of the toilet (12) is higher than either the flush water inlet (18) or the flush water channel (30). The discharge channel (28) extends downward from the rim (22) and enters the toilet (12) at an acute angle with respect to the wash channel (30). By providing the passage (28) in the rim (22) above the wash water channel (30), the passage (28) captures the rising gas generated in the toilet (12) and directs it to the outlet (20).

  FIG. 2b shows how two ventilation fans (14) are combined with each outlet (20) of the toilet bowl (12). In the flow to the end, the fan (14) is connected via a discharge duct (16) to the decompression chamber (50) or alternatively to a vent pipe (not shown). The decompression chamber (50) may be directly ventilated with the outer region through an outer wall (not shown). Alternatively, the decompression chamber (50) may ventilate with an external vent pipe (not shown) coupled to a plurality of toilets.

  In the toilet (10), each odor discharge device (13) is arranged substantially coaxially with each discharge port (20). In other words, the outlet (20), the fan (14) and the outlet duct (16) are coaxial. As a result, the toilet (10) ensures a substantially unrestricted exhaust gas flow path from the toilet. As a result, since the fan (14) does not need to be operated excessively by moving the gas around the restricted device passage, the odor discharging device (13) can discharge the gas more efficiently.

  In order to discharge the gas more effectively, the outlet (20) is tapered outward in the direction in which the gas flows from the toilet, and the remote end of the outlet (20) attached to the fan is the outlet ( The diameter is larger than the opposite end of 20). Furthermore, the first end of the fan (14) and the exhaust duct (16) attached to it has the same diameter as the remote end of the exhaust (20). The second end of the exhaust duct (16) remote from the fan (14) is tapered so that the diameter is progressively smaller than the first end so that the exhaust duct (16) can be attached to a regular drain. Is formed. These relative diameters are, for example, 90 mm in diameter at the remote end of the outlet, the first end of the fan and the exhaust duct, and 40 mm in diameter at the second end of the exhaust duct.

  In a preferred embodiment, the fan (14) is a 12V fan that is powered from the standard wiring circuit of the vehicle to which the building or toilet (10) is attached. The diameter of the fan (i.e., the fan blade) may be chosen so that the toilet (10) can be used as a ventilation unit in a bathroom, public toilet, etc. This eliminates the need to add a fan to remove moisture and the like from the room.

  In one embodiment, the fan is a variable speed fan, and when the toilet is not in use, the fan may be rotated at high speed to exhaust air. However, when the toilet lid is raised or a person sits on the seat of the toilet bowl (12), the switch may be activated to slow down the fan and allow the air to flow through the toilet bowl with a gentler flow.

  The toilet of the present invention is a building structure, such as a house, a communal building, such as a block of flats, an office, a hotel, a static caravan, or the like. Means are provided, for example, in airplanes, trains, buses, mobile houses, caravans and the like.

  In certain applications, for example, if the toilet (10) is provided in an interior room (ie, a room with no exterior walls on the outside), a flexible hose or the like may be used to connect the exhaust duct (16) to the internal vent And the internal vent tube is connected to the main waste outlet as a T-tube. The internal vent pipe may receive discharge from a plurality of toilets (10). Typically, the internal vent tube extends along or above the building where the toilet is provided to centralize ventilation with the outer area. An example of such a case is in a commercial facility such as a hotel or office.

  In use, the toilet (10) is used to exhaust unpleasant gas generated during use of the toilet. This is accomplished by the user operating a switch (not shown) for rotating the exhaust fan (14) that draws air out of the toilet bowl (12) and through the exhaust duct (16). Since at least a portion of the odor outlet (20) is above the flush water inlet (18), it is unlikely that water will be drawn into the drain (13) or part thereof when the toilet is flushed . Further, when the toilet outlet is set as high as possible, the gas rising in the toilet is reliably captured and discharged through the outlet.

  Although the toilet (10) with a pair of odor discharge ports (20) and associated odor discharge devices (13) has been illustrated and described, a toilet (10) as an alternative is a single discharge port. (20) and an odor discharging device (13) may be provided. The single odor discharge device (13) includes a fan (14) and a discharge duct (16) and is connected to the single discharge port (20).

  Furthermore, in the preferred embodiment of the invention shown, the odor discharger (13) and the odor discharge (20) are coaxial with respect to the horizontal axis, but this is not the only possible arrangement. As an alternative, the odor discharge device (13) and the odor discharge port (20) may be coaxial with respect to the vertical axis as shown in FIG. This allows the ejector (13) and the water reservoir (24) to be brought together in a couple of existing water wash water reservoir housings (40) if desired.

  Further, the ventilation fan (14) may be operated by operating a switch of an electric light used for lighting a room with the toilet (10). Alternatively, the ventilation fan (14) may be operated by opening the door of the room where the toilet (10) is located.

  The toilet bowl may further include a toilet seat (toilet seat) (not shown) that accommodates the outlet (20). Regardless of whether the outlet (20) is housed in the sheet, the sheet may have an elastic strip around its lower side. The strip seals between the seat and the toilet bowl (12), at least when a person is sitting on the seat. This seal easily contains odor and ensures that the airflow comes from the front area of the toilet.

The toilet may include one or more odor discharge ports and corresponding odor discharge devices. As the ventilation fan (14), a fan in which non-return vanes are attached to the fan may be used. Thereby, even if a fan stops an operation | movement, air can be prevented from flowing back into a toilet. Alternatively, a check valve may be provided downstream of the fan conduit (ie, on the opposite side of the fan toilet) to prevent outside air from entering the device. Furthermore, in this arrangement, a single speed fan can be used, and the device can also be used for two roles, ie to ventilate the room, and when there are people using the toilet, (12) The fan can be stopped without returning air.
A ventilation fan may be added between the duct (16) and the vent pipe to enhance the airflow through the discharge device (13).

  Other changes and modifications may be incorporated without departing from the scope of the invention.
