Description

[Detailed Description of the Invention] The present invention relates to a deodorizing and purifying device that installs a local fan with a deodorizing filter in a toilet to forcibly purify the toilet so that odors are not diffused.

In the case of a Japanese-style toilet, the conventional technology for deodorizing the toilet is to open the bottom end on one side of the bottom of the toilet bowl.
There is a known device that includes a duct whose outer end is open to the outdoors, and a fan installed at a suitable location within the duct to forcibly remove odors from the toilet. However, in the case of Western-style toilets installed in narrow facilities for special purposes, such as underwater living facilities, inside submarines, mobile toilets, unit baths, etc., where ventilation is insufficient, it is impossible to eliminate the diffusion of odors during defecation. Because of this, people generally had no choice but to put up with the discomfort caused by the emitted odor.

This invention creates a comfortable living environment by forcibly suctioning and deodorizing the odors of defecation in toilets that are located in limited, narrow spaces with insufficient ventilation as described above. The purpose is to preserve it.

To explain the embodiment of the present invention with reference to the drawings, the toilet bowl 1 shown in FIG. is installed, an odor inhaler 5 is connected to the mounting part of the toilet seat 2, and the inhaler 5 and the purification fan 3 are connected through a duct 4 to suction the odor. The suction port of the inhaler 5 communicates with the inside of the toilet or the toilet bowl, and FIGS. 3 and 4 show an example of this. An opening/closing valve that always closes an opening 7 communicating between the inside of the inhaler 5 and the inside of the toilet bowl 1 as shown in FIG. An on-off valve that opens and closes the mouth 10; 11 is a protrusion for opening the on-off valve 6 provided at the attachment part of the toilet seat 2;
Reference numeral 12 denotes an opening rod of the on-off valve 9, which is associated with an interlocking movement rod 13 that operates in conjunction with the opening/closing operation of the on-off valve 6.

Since the present invention is constructed as described above, when the toilet seat 2 is raised up as shown in FIG. 2 after using the toilet,
Since the protrusion 11 of the valve seat base is separated from the on-off valve 6,
The opening/closing valve 6 closes the opening 7 by a spring 8 as shown in FIG. Instead, the opening/closing rod 12 pushes up the opening/closing valve 9 due to the operation of the interlocking rod 13, so the inside of the inhaler 5 and the inside of the toilet are communicated, and the air inside the toilet is sucked into the purification fan by the duct 4. It is then deodorized and purified.

Next, when you go to use the toilet, tilt the toilet seat as shown in Figure 1.
As shown in FIG. 3, the on-off valve 6 is opened by the protrusion 11, and in response, the on-off valve 9 is opened at the vent 10.
Close the toilet bowl 1, suck the odor inside the toilet bowl 1 into the inhaler,
The water is then suctioned and purified by a purification fan through a duct.

According to the present invention, it has become possible to efficiently deodorize the odor caused by defecation as described above, so if the present invention is implemented inside a ship or a building where people are forced to live together, the odor caused by defecation can be removed. This has the effect of preventing the comfort of the living environment from being impaired due to this.

The present invention is applicable not only to the above-mentioned cases, but also to similar environments such as when using a simple toilet bowl for a patient with difficulty walking while hospitalized in a shared room at a hospital, or when deodorizing the toilet bowl in a protective shelter that will be required in the future. This can be provided as an effective means.
