When the claw portion 83 is separated from the claw portion locking portion 417, the deodorizing cartridge attachment portion 8 becomes rotatable and assumes the open position.

[0037] 14, when the deodorizing cartridge attachment part 8 is in the open position, the claw parts 83 are located on the lower side and the upper surface of the cover plate part 81 faces forward. As a result, the deodorizing cartridge 62 attached to the upper surface of the cover plate part 81 is located in front of the cover plate part 81. When the deodorizing cartridge attachment part 8 is in the open position, the deodorizing cartridge 62 can be removed from the deodorizing cartridge attachment part 8, and the deodorizing cartridge 62 can be replaced.

[0038] In the toilet apparatus 1 according to the above embodiment, a space 71 is provided between the suction port 64 of the deodorizing device 6 and the upper surface of the toilet body 2. This allows a configuration in which air from the interior 22 of the toilet bowl 211 is sucked in from the suction port 64 via the space 71 between the suction port 64 and the upper surface of the toilet body 2, even when a portion of the suction port 64 overlaps vertically with the partition section 26 of the toilet body 2 as in this embodiment. This makes it possible to prevent a decrease in the amount of air sucked in by the deodorizing device 6.

[0039] In the toilet apparatus 1 according to the above embodiment, the opening area of ​​the suction port 64 of the deodorizing device 6 is set to be larger than the minimum cross-sectional area of ​​the deodorizing air flow path 61 connected to the downstream side of the suction port 64. This allows the deodorizing device 6 to sufficiently suck in air through the suction port 64 even when a portion of the suction port 64 overlaps with the partition section 26 of the toilet body 2 in the vertical direction, as in this embodiment.

[0040] In the toilet apparatus 1 according to the above embodiment, a plurality of first louver materials 433 (foreign object intrusion prevention parts) are provided at the suction port 64 of the deodorizing device 6, and a space 71 is provided between the plurality of first louver materials 433 and the upper surface of the toilet body 2. This allows a configuration in which air from the interior 22 of the toilet bowl 211 is sucked in from the suction port 64 via the space 71 between the plurality of first louver materials 433 and the upper surface of the toilet body 2. Therefore, a decrease in the amount of air sucked in by the deodorizing device 6 can be prevented without the suction amount being reduced by the plurality of first louver materials 433.

[0041] In the toilet apparatus 1 according to the above embodiment, the suction port 64 of the deodorizing apparatus 6 is located above the lower surface of the bottom plate portion 41, and the first opening 414 (opening) is formed in the bottom plate portion 41 at a position below the suction port 64. As a result, even when the bottom plate portion 41 is installed on the toilet body 2 so that a part of the suction port 64 overlaps with the partition portion 26 of the toilet body 2 in the vertical direction as in this embodiment, a space 71 is formed between the toilet body 2 and the suction port 64. Therefore, the deodorizing apparatus 6 can sufficiently suck air from the suction port 64 through this space 71. In this embodiment, the suction port 64 of the deodorizing apparatus 6 is located above the upper surface of the bottom plate portion 41, so a space 71 whose vertical dimension is larger than the thickness of the bottom plate portion 41 is formed between the toilet body 2 and the suction port 64.

[0042] The present disclosure is not limited to the above-described embodiment, and can be modified as appropriate without departing from the spirit of the present disclosure. For example, in the toilet device 1 according to the above-described embodiment, the suction port 64 of the deodorizing device 6 is disposed at a position overlapping the partition section 26 of the toilet body 2. The suction port 64 may be disposed above the toilet bowl 211 without overlapping the partition section 26 of the toilet body 2.

[0043] For example, in the toilet apparatus 1 according to the above embodiment, the opening area of ​​the suction port 64 of the deodorizing device 6 is set to be larger than the minimum cross-sectional area of ​​the deodorizing air flow path 61. In contrast, the opening area of ​​the suction port 64 may be equal to or smaller than the minimum cross-sectional area of ​​the deodorizing air flow path 61, so long as a predetermined deodorizing performance can be maintained.

[0044] In the toilet apparatus 1 according to the above embodiment, the suction port 64 of the deodorizing device 6 is provided with a plurality of first louver members 433 as a foreign object entry prevention unit that prevents the entry of foreign objects. A foreign object entry prevention unit does not have to be provided. The suction port 64 may be provided with a foreign object entry prevention unit such as a filter instead of the first louver members 433.

[0045] In the toilet apparatus 1 according to the above embodiment, the suction port 64 of the deodorizing device 6 is located above the first opening 414 formed in the bottom plate portion 41 of the functional unit 4, and above the lower surface of the bottom plate portion 41. In contrast, as long as a space 71 is formed between the suction port 64 and the upper surface of the toilet body 2, and air from the interior 22 of the toilet bowl 211 is sucked in from the suction port 64 via this space 71, the suction port 64 does not need to be located above the lower surface of the bottom plate portion 41.

[0046] In the toilet apparatus 1 according to the above embodiment, the functional part 4 is configured to rise and fall relative to the toilet body 2. The functional part 4 does not have to rise and fall relative to the toilet body 2. A fixing part 3 is provided between the toilet body 2 and the functional part 4, but this does not have to be provided. [Explanation of symbols]
