However, the dimensions, materials, shapes, and relative arrangements of the component parts described in this embodiment are not intended to limit the scope of the present invention unless otherwise specified.

The case where this invention is applied to a seat-type flush toilet bowl (henceforth a toilet bowl) is illustrated with reference to FIGS.
The toilet 1 is, for example, a so-called flush valve system that does not have a tank (water tank) that stores water for generating a water flow, and sucks and discharges filth by siphon phenomenon. The toilet 1 includes a toilet main body 3 of sanitary ware from which feces are discharged, an openable / closable toilet seat 5 disposed on the rim 31 of the toilet main body, and a lid 7 that covers the toilet seat 5 and can be opened / closed in the same manner as the toilet seat 5. (See FIGS. 1 and 2).

  The toilet body 3 is fixed to a floor surface or a wall surface by a bolt cap (not shown). The bolt cap is a mounting bolt having a cap on the bolt head. A water supply pipe and a horizontal drainage pipe (not shown) are connected to the toilet body 3.

The water supply pipe is a pipe that is drawn from a water main (not shown) and that feeds water to the toilet body 3. A flash valve is provided in the middle of the water supply pipe.
Then, using the water pressure of the water supply pipe connected to the toilet as it is, water is supplied with a flush valve and washed.

The horizontal drainage pipe is a pipe for cleaning the stool collected in the toilet body 3 with a flush valve and then discharging it outside the site. The horizontal drainage pipe is connected to the rear part of the toilet body 3 using a drainage connection adapter or an elbow which is a bellows-like pipe. The end part (other end) on the opposite side to the toilet body 3 of the horizontal drainage pipe extends toward a sewage pipe (not shown).
The water from the water supply pipe finally flows toward the sewage pipe along with the filth.

Next, the toilet body will be described.
The toilet body 3 is shaped like a tapered bow. Here, the side of the toilet body 3 that is tapered as viewed in plan is the front side, and the opposite side is the rear side. And the pipe body 8 as an exhaust passage is installed in the one side surface (on the left side facing the front of the toilet 1) (see FIGS. 1 and 2). The exhaust passage is drawn out to a place separated from the toilet 1 and communicates with the outside air. A pair of air passages 11 a and 11 b are formed inside the toilet body 3.

  One air passage 11a is configured such that both ends thereof communicate with a pair of openings formed on one side surface of the toilet. The pair of openings is denoted by 111a and 111b (see FIG. 1).

  One end of the other air passage 11 b communicates with an opening 111 c formed on the other side surface of the toilet 1. The other end of the other air passage 11b communicates with the opening 111a.

The opening 111a is installed at a position near the rear of the toilet 1 on one side surface of the toilet 1 and in the vicinity of the floor surface. Similarly, the opening 111b is provided on the front side of the toilet 1 on one side surface of the toilet 1 and in the vicinity of the floor surface. The opening 111c is installed on the other side of the toilet 1 on the near side of the toilet 1 and in the vicinity of the floor. The openings 111b and 111c are open downward.

The pipe body 8 is arranged so that one end 81 thereof communicates with the opening 111a of the toilet 1 and the other end 83 faces outside air (see FIGS. 1 and 2). To face outside air means to be open to the air at a position separated from the toilet, for example, outside a room where the toilet is installed. Therefore, one end 81 of the pipe body 8 communicated with the opening 111 a of the toilet 1 is installed in the vicinity of the floor located on the rear side of the toilet 1.
A ventilation fan 9 connected to the pipe body 8 is connected to the one end 81 of the pipe body 8.

  The ventilation fan 9 is attached to one side of the toilet 1. The ventilation fan 9 is attached to the toilet using a cassette 91 as a case body that houses the ventilation fan 9, and is detachably attached to one side of the toilet 1 (see FIGS. 1 and 2). The attachment / detachment may be a fitting type in which a cassette 91 as a case body is fitted to one side surface of the toilet 1 or a method using an adhesive material. The ventilation fan 9 is positioned between the pipe body 8 and the air passage 11b when attached to the case body.

  A through hole 911 into which one end 81 of the pipe body 8 is inserted is formed in one side surface of the cassette 91 (a surface located on the rear side of the toilet 1 when the cassette 91 is attached to the toilet 1) (see FIG. 2). And the pipe body 8 and the cassette 91 are connected by passing the one end 81 of the pipe body 8 through the through hole 911. As a result, the ventilation fan 9 can suck the air in the air passages 11a and 11b through the opening 111a. Further, when the cassette 91 is attached to the toilet bowl 1, the ventilation fan 9 in the cassette 91 and the opening 111 a provided on one side surface of the toilet body 3 are opposed to each other.

  Filters 10 and 10 for removing dust are installed in the openings 111b and 111c provided on both sides of the toilet body 3 (see FIGS. 1 and 2).

  Filters 10 and 10 are connected to ventilation fan 9 via air passages 11a and 11b inside the toilet body (see FIGS. 1 and 3). Filters 10 and 10 prevent dust and small dust from flowing to the side of the ventilation fan 1 from both sides of the toilet 1, that is, both sides of the toilet 1 and the vicinity of the floor when the ventilation fan 9 is driven. It is. Thereby, only air flows to the ventilation fan 9 side.

  The air passages 11 a and 11 b are formed so that one air passage 11 a is formed along the longitudinal direction of one side surface of the toilet body 3 and the other air passage 11 b crosses the toilet body 3. Are connected to the ventilation fan 9 (see FIGS. 1 and 3).

  Moreover, since the said one end 81 of the pipe body 8 is installed in the vicinity of the floor surface located in the back side of the toilet bowl 1 as stated above, the ventilation fan 9 attached to the said one end 81 is also below the back side of the toilet bowl 1 below. Located near the floor (see FIGS. 1 and 2).

Since the toilet 1 has such a configuration, the lower part of the toilet 1, particularly the floor surface on the near side of the toilet 1, communicates with the outside air through the pipe body 8 and the air passages 11 a and 11 b. Then, by driving the ventilation fan 9, the odor of the urine 100 leaking or adhering to the floor surface around the toilet bowl is attached to the front side of both sides of the toilet bowl 1 and in the vicinity of the floor surface. The air is sucked through (see the arrow in FIG. 1), and then released to the outside air through the pipe body 8. Therefore, it does not cause discomfort to the toilet user due to the bad smell of urine. Therefore, at least the pipe body 8 and the ventilation fan 9 can be said to be a floor surface deodorizing ventilation device.

The other end of the pipe body 8 is not limited to the front of the toilet, but may be positioned on the rear side of the toilet or on both the front and rear.
Further, the ventilation fan 9 may be attached in the middle of the pipe body 8 or using a tip opening joint means of the pipe body 8.

  Further, in this embodiment, the air passages 11a and 11b are formed inside the toilet body 3, but the present invention is not limited thereto. For example, a cover body that covers the peripheral side surface of the toilet body 3 in a skirt shape may be provided, and a ventilation fan may be installed in the space formed between the cover body and the toilet body 3 in addition to the air passage. .

  An odor sensor for measuring the ammonia odor and a control unit for inputting a detection signal from the odor sensor may be provided, and the ventilation fan may be controlled by an instruction signal from the control unit. The odor sensor is installed on the toilet body so as to be located on both sides of the toilet 1 and in the vicinity of the floor surface. Then, when the value of the odor concentration detected by the odor sensor exceeds the set value, the control unit can be controlled to operate the ventilation fan.

  Further, the control unit may control the propeller rotational speed per unit time of the ventilation fan to change depending on the level of the odor concentration detected by the odor sensor. For example, when the odor concentration value detected by the odor sensor exceeds the first set value, the control unit controls the propeller of the ventilation fan to rotate at a low speed, and the odor concentration value is higher than the first set value. The control unit can control the propeller of the ventilation fan to rotate at a high speed when the second set value is exceeded.

  Furthermore, the present invention can be applied to a toilet having a tank (water tank) for storing water for generating a water flow. Of course, the wall-mounted toilet system and the floor-mounted toilet system can be applied to both.
