DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet bowl deodorizing device. More specifically, the present invention relates to a toilet deodorizing device capable of efficiently and reliably deodorizing odors in a toilet and preventing backflow of odors.

[0002]

2. Description of the Related Art Conventionally, there has been known a toilet-integrated deodorizing device having a deodorizing unit for removing odor in a toilet bowl. For example, in the conventional deodorizing device illustrated in FIG. 4, an intake pipe (c) and an exhaust pipe (d) connected to a deodorizing unit (a) installed in a toilet body (a) are connected to a bowl (e) and a drain. Each is connected to a pipeline (f).
With this device, the odor in the bowl portion (e) is exhausted by the deodorizing unit (a) to the drain pipe (f) via the intake pipe (c) and the exhaust pipe (d).

Further, as shown in FIG. 5, a valve such as a solenoid valve having a valve body (g) such as a packing at the inlet of an exhaust pipe (d) is arranged inside the deodorizing unit (a). Yes. When the deodorizing unit (a) is stopped, the exhaust pipe (d) is closed with the valve body (g), and the odor is drained as shown in Fig. 4 (f).
From backflow. In addition, as shown in FIG. 6, there is also known a deodorizing device in which an exhaust pipe (d) connected to a deodorizing unit (a) is connected to a water sealing part (h) in a drainage pipe of a toilet (a). ing.

[0004]

However, in the conventional deodorizing apparatus illustrated in FIG. 4, for example, dust or paper debris is often sucked from the intake pipe (c) when the odor is removed. There is a problem that dust or the like is clogged in the body (g), and the exhaust pipe (d) cannot be completely shielded. Therefore, there is a disadvantage that the odor flows backward from the exhaust pipe (d) and the odor drifts in the toilet room. To prevent this, it was necessary to perform maintenance work several times throughout the year, which was cumbersome.

On the other hand, in the case of the deodorizing device shown in FIG.
There is a drawback that the pressure loss in the water sealing portion (h) is large, and therefore, the deodorizing efficiency is deteriorated. The present invention has been made in view of the above circumstances, and eliminates the disadvantages of the conventional deodorizing device, efficiently and surely deodorizes the odor in the toilet, and also prevents the odor from flowing back. It is an object of the present invention to provide a toilet bowl deodorizing device capable of performing the following.

[0006]

According to the present invention, there is provided a deodorizing apparatus for a toilet in which an intake pipe and an exhaust pipe connected to a deodorizing unit are respectively connected to a toilet bowl and a drain pipe. Wherein a sealed container containing a liquid is provided in the deodorizing unit, and an air pipe and an exhaust pipe are connected to the sealed container, and a pipeline opening / closing device for vertically moving the air intake pipe is provided. Provide a toilet bowl deodorizing device.

[0007]

In the toilet bowl deodorizing apparatus of the present invention, a liquid-containing closed container is provided in the deodorizing unit, and an intake pipe and an exhaust pipe are connected to the closed container, and a pipe line for vertically moving the intake pipe. Since the opening and closing device is provided, the odor in the toilet can be efficiently and reliably deodorized. Even when the deodorizing pipe is clogged with dust or the like, for example, the pipe can be completely shut off when the deodorizing unit is stopped, and the backflow of odor can be prevented.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a toilet bowl deodorizing apparatus according to an embodiment of the present invention. FIG.
1 is a sectional view showing an embodiment of a deodorizing device for a toilet according to the present invention. For example, in the apparatus illustrated in FIG. 1, an intake pipe (3) connected to a deodorant unit (2) integrally installed on the toilet body (1) faces the upper part of the bowl (4). An exhaust pipe (5) connected to the deodorizing unit (2) is connected to a drain pipe (6). The odor in the bowl (4) of the toilet (1) is exhausted by the deodorizing unit (2) to the drain pipe (6) via the intake pipe (3) and the exhaust pipe (5).

FIG. 2 is an enlarged sectional view showing the deodorizing unit shown in FIG. In the example of FIG. 2, a container (8) containing a sealing liquid (7) is provided, and the container (8) is provided with a flexible packing as a part of an intake pipe via a sealing gasket (9). The tube (10) is connected. The flexible pipe (10) is connected to a deodorizing fan (11), and communicates with the intake pipe (3) illustrated in FIG. 1 via the deodorizing fan (11). The container (8) is also connected to the exhaust pipe (5) illustrated in FIG. Examples of the sealing liquid (7) that can be put in the container (8) include water, grease, oil, and the like. If there is no evaporation or decay other than water, there is no need to replenish or replace. The sealing liquid (7) can be introduced into the container (8) to the depth of the connection of the exhaust pipe (5), as illustrated in FIG.

The flexible pipe (10) is provided with a pipe opening / closing device comprising a drive motor (12), a pinion (13) and a rack (14). The flexible pipe (10) moves up and down in the direction of the arrow shown in the figure by this pipeline opening / closing device. The state of FIG. 2 shows a state in which the deodorizing unit (2) is stopped, and the flexible pipe (10) is immersed in the sealing liquid (7) in the container (8), and the suction pipe (3). The deodorizing pipelines such as the exhaust pipe (5) are shut off. For this reason, the odor from the drainage pipe (6) illustrated in FIG. 1 does not flow back to the bowl (4) of the toilet (1).

FIG. 3 shows the operating state of the deodorizing unit (2). By driving the drive motor (12), the flexible tube (10) rises and the container (8)
It is pulled up from the sealing liquid (7) inside. The flexible pipe (10) communicates with the exhaust pipe (5) through the space in the container (8), thereby opening the deodorizing pipe. The odor in the bowl part (4) of the toilet bowl (1) illustrated in FIG. 1 is discharged by the deodorizing fan (11) through the intake pipe (3), the flexible pipe (10) and the exhaust pipe (5), and then to the drain pipe. It is discharged to (6). The odor in the bowl (4) can be efficiently and reliably removed.

When the deodorizing unit (2) is stopped, the drive motor (12) is driven again, the flexible pipe (10) is lowered, and the flexible pipe (10) is immersed in the sealing liquid (7) in the container (8). . As is clear from the above example, in the deodorizing device of the present invention, even when dust or paper debris is clogged inside the deodorizing pipeline such as the intake pipe and the exhaust pipe, the pipeline is completely shut off. can do. Therefore, the backflow of the odor from the drainage pipe can be reliably prevented.

Of course, the present invention is not limited by the above examples. It goes without saying that various aspects are possible for details such as the structure and configuration of the toilet and the pipeline opening and closing device, and the type of the sealing liquid.

[0014]

As described above in detail, according to the present invention, there is provided a deodorizing apparatus capable of efficiently and reliably deodorizing odors in a toilet bowl and preventing odor backflow.
