CONSTITUTION: A vacuum pipe 3 is connected to a western water closet 2 in a toilet room 1, and deodorizing pipes 12 and 13 branched from the vacuum pipe 3 are connected to a rim water passage and an exhaust port 16 through deodorizing valves 14 and 15. When a user sits on a stool of the water closet, the valves 14 and 15 are opened to deodorize.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum type toilet device in which vacuum piping is connected to a toilet bowl in a toilet room,
In particular, it relates to a vacuum type toilet device incorporating a deodorizing mechanism.

[0002]

2. Description of the Related Art A vacuum drainage system for evacuating a sewer pipe and collecting sewage by using a pressure difference is becoming popular. This vacuum drainage system does not require gravity draining, so no drainage gradient is required, and there is no need to bury the sewer pipe deeply, which minimizes construction work.
It has many advantages such as being able to deal with areas where excavation work is difficult, such as narrow alleys and winding alleys.

Further, an indoor vacuum drainage system has been developed for draining domestic wastewater and miscellaneous drainage from kitchen, toilet, bathroom, etc. through a vacuum type indoor pipe.

[0004]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention As a deodorizing device from a toilet bowl or a toilet room, a fan or the like is used to discharge an odor to a drain pipe or the outside of the toilet room.
The power cost of the fan is high and the space for installing the fan is required.

It is an object of the present invention to provide a vacuum type toilet device which uses a vacuum type indoor drainage system to efficiently deodorize a toilet room or a toilet bowl.

[0006]

The vacuum toilet device of the present invention is a vacuum toilet device in which a toilet is installed in a toilet room and a vacuum pipe is connected to a drain port of the toilet via a drain valve. A deodorizing device for inhaling air from at least one of the toilet bowl and the toilet room is connected to the vacuum pipe.

[0007]

[Operation] Odor can be efficiently discharged from the toilet room or the toilet by using the negative pressure in the vacuum piping. In this case, no fan need be installed.

Embodiments will be described below with reference to the drawings. FIG. 1 is a side view of a vacuum type toilet device according to an embodiment of the present invention, FIG. 2 is a longitudinal sectional view of a Western-style toilet used in this embodiment device, and FIG. 3 is a control system of the embodiment device. It is a block diagram shown.

A Western-style toilet 2 is installed in a toilet room 1 and a vacuum pipe 3 is connected. A toilet seat 4 and a low tank 5 are installed on the upper surface of the Western-style toilet 2.

As shown in FIG. 2, a rim water passage 7 is provided around the upper part of the toilet bowl 6 of the Western-style toilet 2,
Water from the low tank 5 passes through the water supply port 8 to the rim water passage 7
The water is discharged from the water spray port 9 into the toilet bowl 6. A drain valve 11 is connected to a drain port 10 of the toilet bowl 6, and the vacuum pipe 3 is connected to the drain valve 11.

A toilet deodorizing pipe 12 and an indoor deodorizing pipe 13 are branched from the vacuum pipe 3. The toilet deodorizing pipe 12 communicates with the rim water passage 7 via the toilet deodorizing valve 14.
The indoor deodorizing pipe 13 is provided with an exhaust port 16 via an indoor deodorizing valve 15.
Is in communication with. The exhaust port 16 is provided below the wall 17 of the toilet room 1.

A deodorizing switch 18 and a flash switch 19 are provided on the wall 17. The low tank 5 is provided with an electric flash valve 20 which is operated by the flash switch 19. The toilet seat 4
Is equipped with a seating sensor, as shown in FIG.
The detection signal of the seating sensor 21 is the switch 18, 19
It is input to the controller 22 together with the signal from. The controller 22 outputs a control signal to the electric flash valve 20, the drain valve 11, and the deodorizing valves 14 and 15.

In the vacuum type toilet device constructed as above, when the user sits on the toilet seat 4, the controller 22
Based on the seating detection signal from the seating sensor 21, the toilet deodorizing valve 14 and the indoor deodorizing valve 15 are opened. This allows
Due to the negative pressure in the vacuum pipe 3, the rim water passage 7 and the exhaust port 1
Odors in the toilet bowl 6 and the toilet room 1 are sucked from 6 to deodorize. When the user stands up from the toilet seat 4, the controller 22 controls the deodorizing valves 14, 15 after a predetermined time has elapsed.
Close the valve.

When the user operates the flush switch 19, the controller 22 opens the electric flush valve 20 and the drain valve 11, and the wash water is introduced into the toilet bowl 6 from the raw tank 5. The cleaning water is discharged to the vacuum pipe 3 together with the dirt. The electric flash valve 20 automatically closes when the water level in the low tank 5 drops to a predetermined level. The drain valve 11 is closed by the controller 22 after a predetermined time has elapsed. The toilet deodorizing valve 14 may be closed while the cleaning water is being supplied into the rim water passage 7.

In the present embodiment, when the deodorizing switch 18 is operated, the controller 22 opens the toilet deodorizing valve 14 and the indoor deodorizing valve 15 for a predetermined time to deodorize the toilet bowl 6 and the toilet room 1 for a predetermined time. To do. In addition, this deodorant switch 1
As 8, a timer switch whose operation time can be adjusted may be used.

In the present invention, the deodorizing switch 18 is set to 1
The deodorizing valves 14 and 15 may be opened by pressing the switch once, and the deodorizing valves 14 and 15 may be closed by pressing the deodorizing switch 18 once again.

Although the valves 11, 14 and 15 are electrically driven in the above embodiment, the negative pressure in the vacuum pipe 3 may be used as the operating power source.

Although the odor in the toilet bowl 6 is discharged through the rim water passage 7 in the above embodiment, the toilet seat 4 is provided with an intake port, and the toilet seat 4 is connected to the toilet deodorizing pipe. Is also good.

Although the exhaust port 16 is provided in the lower portion of the toilet room 1 in the above embodiment, it may be provided in other places.

Although the western style toilet 2 is used in the above embodiment, a Japanese style toilet may be used.

[0021]

As described above, according to the vacuum type toilet device of the present invention, the odor in the toilet bowl or the toilet room can be efficiently discharged by utilizing the vacuum piping.

According to the present invention, a fan for discharging odors is not required, and a fan installation space is also unnecessary.
