[Industrial applications]

 The present invention mainly relates to facilities of toilets installed in places used by many people such as schools, offices, department stores, and public buildings.

[0002]

[Prior Art]

 Conventionally, with respect to flush toilet devices, many inventions and inventions have been made to improve the cleaning action of the flush water and to save the amount of water used, but with regard to the toilet room, simple exhaust and installation of fragrance have been proposed. Only. In addition, as an exhaust device for flush toilets, there is a plan to equip an exhaust pipe branched from the flush water supply pipe with an automatic switching valve to discharge odors outside the toilet room (Actual No. 51-78640), and also a valve for the exhaust pipe. An exhaust system (Shinkai Sho 49-55852) has been proposed which prevents backwash water from flowing back to the discharge pipe due to the ventilating effect of the discharge water flow.

However, regarding soundproofing, only toilet bowls that emit on-the-spot sound for women have been developed. In addition, the vacuum suction type flush toilet equipment, which was developed to save the amount of water used and to freely connect the height of the wastewater distribution pipe, has the drawback that the noise generated in the toilet bowl during drainage is large.

In view of the above circumstances, the present invention has an object to propose a toilet facility that does not leak odor and noise during stool use and during drainage to the outside of the toilet room, and that is comfortable in the toilet room. It

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, the flush water led from the elevated water tank 34 or the direct water pipe to the water supply pipe 12 is supplied from the pipe 14 to the toilet 10 by the action of the flush valve 11, and a part thereof flows out from the many holes 16. After cleaning the inner surface of the toilet, it is discharged to the discharge pipe 17 together with the dirt. A branch pipe 13 is installed between the flush valve 11 and the pipe 14, and is branched from the flow path of the washing water to connect an exhaust pipe 15. The other end of the exhaust pipe is an exhaust device 35 installed outside the toilet room. It is connected to the intake port of. FIG. 2 shows the structure of the branch pipe 13. A nozzle 18 projects from the flash valve 11 into the branch pipe, and the nozzle has a smooth throttle surface 19. Therefore, the washing water supplied from the flush valve becomes a jet flow from the nozzle 18 and drops into the pipe 14, which prevents the washing water from flowing back to the exhaust pipe 15 due to the Venturi effect. When the flush water is not supplied, the residual water level in the toilet bowl is lowered, so the air in the toilet bowl space is exhausted from the toilet hole 16 through the pipe 14, branch pipe 13, and exhaust pipe 15 by the exhaust device 35 to the outside of the toilet. .. Therefore, the odor in the stool is discharged to the outside of the lavatory through the exhaust pipe without being diffused into the lavatory.

FIG. 3 shows the structure of the upper part of the toilet, and the toilet seat 20 rotatably attached so as to contact the upper surface of the toilet main body 10 with the hinge 25 is a continuous ring without cutouts and the lower surface which contacts the upper surface of the toilet. The packing 21 is attached. Similarly, the lid 22, which is openably and closably attached to the toilet seat 20 by the hinge 25, is made of a sound-insulating material such as a damping steel plate, and the packing 23 is attached to the surface contacting the toilet seat. Therefore, when the lid 22 is closed, the space inside the toilet becomes airtight, and even a vacuum drainage type flush toilet causes less noise to leak to the toilet room when draining. In this way, even if the space inside the toilet bowl is airtight with respect to the toilet room, air will flow back from the exhaust pipe, and there will be no hindrance to draining the washing water. Further, the switch 26 attached to the lower surface of the lid 22 is turned on when the lid is closed, and this signal stops the exhaust device 35 so that the power can be saved. When exhausting multiple toilets with one exhaust device, stop when all the switches are ON and operate when any one of the switches is OFF.

Next, the configuration of the entire toilet room will be described with reference to FIG. The flush toilet 10 described in FIGS. 1 to 3 is attached to the floor of the toilet surrounded by the wall 30, the lid 22 of the toilet is opened, and the exhaust device is operated during the toilet to operate the air between the toilet inner chambers. Is discharged to the outside of the toilet via the pipe 14, the branch pipe 13, and the exhaust pipe 15, so that the odor does not diffuse into the toilet. A duct 33 is connected to an air intake 32 provided on the wall 30, and the other end of the duct is open to the outside air, so that the air in the toilet room discharged by the exhaust device 35 is naturally placed by the outside air. Will be replaced. By connecting the other end of the duct 33 to the discharge port of the air conditioner installed outside the toilet room, the inside of the toilet room can be air-conditioned. Further, when the flush toilet lid 22 is closed and the flush valve 11 is operated, the flush water is supplied from the elevated water tank or the water pipe 34 to the toilet bowl 10 through the water supply pipe 12, the flush valve 11, the branch pipe 13 and the pipe 14. It is discharged to the water distribution pipe 17 together with the waste. At this time, since the toilet bowl 10 is closed by the lid 22, the noise leaking out of the toilet bowl when the drainage falls is small. When the lid 22 is closed, the operation of the exhaust device 35 automatically stops, so that the power loss is small.

A door 31 having a sound insulating structure is attached to the passage side wall 30a of the toilet room in an airtight state. That is, in FIG. 5, the door 31 is composed of three layers of a sound absorbing plate 40, a sound insulating plate 41, and a decorative plate 42 from the toilet side, and is attached to the wall 30a by a hinge 45 so as to be openable and closable. When the door is closed by the packing 43 attached to the wall, the inside of the toilet is airtight. Therefore, the sound of excretion in the stool does not leak to the outside of the toilet, and the loss due to air leakage when the toilet is air-conditioned can be prevented. Further, the sound absorbing plate 40 prevents the echo of noise generated in the toilet room.

[0009]

[Effect of the device]

 As described above, in the present invention, the exhaust pipe is provided by branching from the water supply line that supplies the flush water to the flush toilet, and the toilet bowl is sealed with the lid, so that the odor in the toilet is diffused into the toilet room. It is directly discharged from the exhaust pipe to the outside of the toilet without any trouble, and the noise when flushing water is drained is unlikely to leak to the outside of the toilet.

Further, since the entrance / exit door of the toilet room has a sound-insulating and airtight structure, it is difficult for the installation sound in the toilet to leak outside the toilet room. Furthermore, since the outside air or conditioned air is supplied to the toilet room, the inside of the toilet room becomes comfortable.
