Abstract

A toilet device includes a casing and a deodorizing unit provided inside the casing and configured to deodorize air in a toilet room. The deodorizing unit includes a duct and a fan configured to suction air into the duct. The duct includes a first extending portion extending from the casing, a second extending portion extending from the casing at a position different from a position of the first extending portion, and a connection portion connecting the first extending portion and the second extending portion. The first extending portion, the second extending portion, and the connection portion are integrally formed with the casing.

Claims (66)

1 . A toilet device comprising:

a casing; and

a deodorizing unit provided inside the casing and configured to deodorize air in a toilet room, wherein

the deodorizing unit includes

a duct, and

a fan configured to suction air into the duct,

the duct includes

a first extending portion extending from the casing,

a second extending portion extending from the casing at a position different from a position of the first extending portion,

a connection portion connecting the first extending portion and the second extending portion, and

an attaching portion for attaching the fan to the duct, and

the first extending portion, the second extending portion, and the connection portion are integrally formed with the casing, and

the attaching portion is open upward.

2 . The toilet device according to claim 1 , wherein

the duct includes

an intake through which air is suctioned,

an exhaust port from which deodorized air is exhausted, and

a passage portion via which the intake and the exhaust port communicate with each other, and

the passage portion is integrally formed with the casing from the intake to the exhaust port.

3 . The toilet device according to claim 2 , wherein

the fan includes a rotary shaft extending upward with respect to a bottom surface portion of the casing, and

the fan exhausts air in a direction orthogonal to the rotary shaft.

4 . The toilet device according to claim 2 , wherein

the passage portion includes

a first passage portion positioned on the intake side, and

a second passage portion positioned on the exhaust port side, and

the fan is disposed between the first passage portion and the second passage portion.

5 . The toilet device according to claim 4 , wherein

the second passage portion is bent at an obtuse angle in a flow direction of air.

6 . The toilet device according to claim 1 , wherein

the casing includes a fixing portion at which the fan is fixed with a screw.

7 . A toilet device comprising:

a casing; and

a deodorizing unit provided inside the casing and configured to deodorize air in a toilet room, wherein

the deodorizing unit includes

a duct, and

a fan configured to suction air into the duct,

the duct includes

an intake through which air is suctioned,

an exhaust port from which deodorized air is exhausted, and

a passage portion via which the intake and the exhaust port communicate with each other, the passage portion being formed by a first extending portion extending from the casing, a second extending portion extending from the casing at a position different from a position of the first extending portion, and a connection portion connecting the first extending portion and the second extending portion, and wherein

the first extending portion, the second extending portion, and the connection portion are integrally formed with the casing from the intake to the exhaust port.

8 . The toilet device according to claim 7 , wherein

the fan includes a rotary shaft extending upward with respect to a bottom surface portion of the casing, and

the fan exhausts air in a direction orthogonal to the rotary shaft.

9 . The toilet device according to claim 7 , wherein

the passage portion includes

a first passage portion positioned on the intake side, and

a second passage portion positioned on the exhaust port side, and

the fan is disposed between the first passage portion and the second passage portion.

10 . The toilet device according to claim 9 , wherein

the second passage portion is bent at an obtuse angle in a flow direction of air.

11 . The toilet device according to claim 7 , wherein

the casing includes a fixing portion at which the fan is fixed with a screw.

12 . A toilet device comprising:

a casing; and

a deodorizing unit provided inside the casing and configured to deodorize air in a toilet room, wherein

the deodorizing unit includes

a duct, and

a fan configured to suction air into the duct,

the duct includes

a first extending portion extending from the casing,

a second extending portion extending from the casing at a position different from a position of the first extending portion, and

a connection portion connecting the first extending portion and the second extending portion, and

the first extending portion, the second extending portion, and the connection portion are integrally formed with the casing, wherein

the casing includes a fixing portion at which the fan is fixed with a screw.
