Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a flush toilet having a deodorizing function, and more particularly to a flush toilet using an existing water supply pipe so as to obtain a desired deodorizing function with a simple configuration.

[0002]

[Prior art]

 As a flush toilet, for example, the one in which the flush toilet is installed to ventilate the room to deodorize the room is common. In this case, a ventilation fan is installed in an appropriate place in the room, and the ventilation fan is activated at the time of use to achieve ventilation and deodorization in the room.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional configuration has the following problems. That is, it is possible to ventilate the room by installing and using a ventilation fan to deodorize it, but in order to obtain a sufficient deodorizing effect, it is necessary not only during use but also after use. It was necessary to keep the ventilation fan running. In addition, as described above, it takes a long time to obtain a sufficient deodorizing effect. For example, when one person uses the same immediately after another person uses it, There was a problem that it was unpleasant because it was not properly deodorized. Various proposals have been made for such a problem, but none of them has a complicated structure and can be easily applied to existing equipment.

The present invention has been made on the basis of such a point. The object of the present invention is to make it possible to obtain a sufficient deodorizing effect and to easily apply it to existing equipment. The purpose is to provide a flush toilet that can.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the flush toilet according to the present invention comprises a flush tank, a toilet bowl that is installed separately from the flush tank, and a flush toilet installed between the flush tank and the flush bowl. It is characterized in that it is provided with a water supply pipe for supplying the water to the toilet bowl, a deodorizing pipe branched and connected to the water supplying pipe, and a deodorizing fan inserted in the deodorizing pipe. At that time, it is possible to turn on / off the deodorizing fan with a separately installed switch. It is also possible to turn on / off the deodorizing fan with a switch provided on the seat of the toilet bowl. Furthermore, it is conceivable to open the deodorizing pipe indoors and attach a deodorizing filter to the open end.

[0006]

[Action]

 That is, in the case of the present invention, the flush toilet which is one of the existing facilities, that is, the flush pipe arranged between the flush tank and the toilet bowl is used to provide the flush toilet with the desired deodorizing device. The deodorizing pipe is branched and connected to the water supply pipe, and a deodorizing fan is inserted there. Therefore, for example, immediately after defecation, the odor can be exhausted through the water supply system of the toilet bowl, the water supply pipe, and the deodorizing pipe. Regarding the turning on / off of the deodorizing fan, for example, it is conceivable to use a switch provided separately or to use a switch attached to the toilet bowl. It is also possible to open the tip of the deodorizing pipe indoors and attach a deodorizing filter to the open end. In that case, it is easy to install the deodorizing pipe.

[0007]

[Embodiment of device]

 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a side view showing a part of the inside of the toilet room in which the flush toilet is installed. A flush tank 3 is attached and fixed at an appropriate level position inside the side wall 1. A water supply pipe 5 is connected to the washing tank 3 so that washing water is supplied from a water supply source (not shown) (for example, tap water). A toilet bowl 9 is attached / fixed to a predetermined location on the floor 7. A valve seat 11 is rotatably attached to the upper end of the toilet bowl 9.

A water supply pipe 13 is arranged between the toilet bowl 9 and the flush tank 3. The configuration of the upper end of the toilet 9 is shown in FIG. First, the water supply channel 15 is provided in an annular shape, and a large number of ejection holes 17 are formed on the inner surface of the water supply channel 15. Then, the water supplied into the water supply passage 15 through the water supply pipe 13 is ejected into the toilet bowl 9 through the large number of ejection holes 17, whereby filth is made to flow. Is.

A deodorizing pipe 19 is branched and connected to the water supply pipe 13, and the deodorizing pipe 19 extends upward along the side wall 1. Further, the upper end of the deodorizing pipe 19 is bent by 90 °, and is projected and arranged outside the room through the through hole 23 of the side wall 1. A deodorizing fan 21 is inserted in the deodorizing pipe 19. The deodorizing fan 21 has a structure as shown in FIG. That is, the fan 21b is rotatably arranged in the casing 21a, and the fan 21b is rotated by the drive motor 21c arranged outside the casing 21a.

The drive motor 21c is turned on / off by operating the switch 25. Further, as shown in FIG. 3, a check valve 27 is inserted on the exhaust side of the deodorizing fan 21.

The operation will be described based on the above configuration. First, when it is used, it is seated on the valve seat 11, the switch 25 is turned on, and the deodorizing fan 21 is rotated. As a result, the route connecting the deodorizing pipe 19, a part of the water supply pipe 13, and the water supply flow path 15 functions as a deodorizing route. It will be exhausted. After defecation, the knob 3a of the flush tank 3 is rotated to supply the water in the flush tank 3 to the toilet 9 side. As a result, the water in the flush tank 3 is ejected into the toilet bowl 9 through the water supply pipe 13, the water supply flow path 15, and the large number of ejection holes 17, whereby filth is made to flow. The deodorizing action of the deodorizing fan 21 is continued during that period, and the switch 25 may be turned off when the user leaves the flush toilet room after use.

According to the present embodiment as described above, since the odor can be effectively discharged during and after defecation, the odor does not spread in the flush toilet room, and thus the ventilation fan can be used for a long time as in the conventional case. There is no need to drive it. Moreover, even if another person uses the equipment immediately after use, it does not cause any discomfort. Further, as the equipment, since the deodorizing pipe 19 is branched and connected to the existing water supply pipe 13 and the deodorizing fan 21 is inserted, it is extremely simple and can be easily applied to the existing equipment.

Next, a second embodiment of the present invention will be described with reference to FIG. In this case, in the first embodiment, the secondary side of the deodorizing fan 21 of the deodorizing pipe 19 is opened in the room, and the deodorizing filter 31 is attached thereto. In this case, since it is deodorized by the deodorizing filter 31, it is not necessary to intentionally exhaust it to the outside. In addition, the amount of material is reduced by that much, and since it is not necessary to provide the through hole 23 in the side wall 1, the construction becomes easy.

The present invention is not limited to the first and second embodiments. For example, the deodorizing fan 21 may be turned on / off by a switch provided on the valve seat 11. In this case, when the user sits on the valve seat 11, the switch is automatically turned on, thereby starting the deodorizing fan 21, and conversely, by separating from the valve seat 11. The switch is automatically turned off, and the deodorizing fan 21 is stopped accordingly. The branching / connection position of the deodorizing pipe 19 with respect to the water supply pipe 13, the subsequent installation route, and the like may be arbitrarily determined. Further, in the above-mentioned one embodiment, a so-called style toilet has been described as an example, but a Japanese style toilet may be used.

[0015]

[Effect of device]

 As described above in detail, according to the flush toilet of the present invention, it is possible to provide a desired deodorizing function without using the existing equipment and making a great change, and to eliminate the odor generated in the toilet bowl. Since it is configured to suck and exhaust in the vicinity thereof, a high deodorizing effect can be expected. Further, if the deodorizing filter is provided inside the room, the construction becomes simpler.
