You.

[0016]

In the hot water washing apparatus according to the present invention, since a part of the casing of the fan is formed together with the toilet seat box, the number of parts and the number of assembling steps can be reduced.

According to the second aspect of the present invention, it is possible to
The mounting portion of the deodorizing cartridge can be formed firmly.

[0018]

Embodiments will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of a hot water cleaning device according to an embodiment,
8 and 9 are sectional views taken along lines VIII-VIII and IX-IX of FIG.

The lower half 50 of the toilet seat box of the hot water washing apparatus according to this embodiment is an injection-molded article made of synthetic resin. A lower casing portion of the deodorizing fan 52 is integrally formed with the lower half portion 50. That is, the lower half 50 is provided with the annular wall 54 that forms the outer periphery of the lower part of the outer shell of the deodorizing fan 52. A part of the annular wall 54 on the front side of the toilet seat box serves as a suction side opening 56.
A pair of flat walls 58, 60 extend toward the front of the toilet seat box.

A part of the annular wall 54 on the side of the toilet seat box serves as a discharge opening 62, from which a pair of flat walls 64, 66 extend toward the side of the toilet seat box. Has been issued. An opening 68 is provided in the lower part 50 of the toilet seat box at a portion sandwiched between the flat walls 64 and 66.

A rectangular cylindrical discharge duct 70 extends downward from the lower surface of the peripheral portion of the opening 68. The discharge duct 70 is formed integrally with the lower half 50 of the toilet seat box. The deodorizing cartridge 46 is inserted into the discharge duct 70. That is, the discharge duct section 70 is a mounting section for the deodorizing cartridge 46.

The annular wall 54 and the planar walls 58, 60,
The upper casing 72 is mounted on the upper portions 64 and 66 from above. The upper casing 72 includes a circular portion 74 that covers the annular wall 54, an extending portion 76 that extends toward the front of the toilet seat box so as to cover the flat walls 58 and 60, and a flat wall 6.
An extension 78 extends toward the side of the toilet seat box so as to cover the toilet seats 4, 66. A plurality of claws 80 project downward from the lower edge of the upper casing 72, and the claws 80 are engaged with the upper edges of the annular wall 54 and the planar walls 58, 60, 64, 66. An engaging hook 82 is provided. The upper casing 72 is connected and fixed to the lower half portion 50 of the toilet seat box by engaging the claw portion 80 with the hook portion 82. The upper casing 72 is provided with a motor 36 and a propeller 34.

Although not shown, other equipment such as a washing nozzle and a hot water tank are attached to the lower half portion 50 of the toilet seat box, and the upper half portion of the toilet seat box is connected to the lower half portion 50 as in the conventional example. A warm water washing device is configured by assembling the device.

In the thus constructed hot water washing apparatus as well, the deodorization is performed by operating the motor 36 and rotating the propeller 34.

The annular wall 54, the flat walls 58, 60, 64, 66 and the discharge duct 70 which constitute the lower half of the outer shell of the deodorizing fan are formed integrally with the toilet seat lower half 50. Thus, the number of parts of the deodorizing fan and the number of assembly steps can be reduced. In particular, in this embodiment, since the discharge duct portion 70 as a mounting portion of the deodorizing cartridge 46 is formed integrally with the lower half portion 50 of the toilet seat box, the discharge duct portion 70 is made strong. Therefore, even if the deodorizing cartridge 46 is roughly attached to and detached from the discharge duct unit 70, the discharge duct unit is not easily broken.

[0026] Under the deodorizing fan in the above embodiment casings grayed
The but be integrated with the lower half of the toilet seat box, the casings grayed on the deodorizing fan may be integrated with the upper half of the toilet seat box. Also, when a hot air fan is installed, the upper casing or lower casing of the hot air fan may be formed integrally with the lower half or upper half of the toilet seat box. Also,
Not only this fan but also a part or the whole of other synthetic resin equipment such as a hot water tank may be formed integrally with a part of the toilet seat box.

[0027]

[Effects of the Invention] As described above, in the hot water washing apparatus of the present invention, a part of the fan casing is integrated with a part of the toilet seat box, thereby reducing the number of parts and the number of assembly steps. Thus, the manufacturing cost of the hot water cleaning device is reduced.

According to the second aspect of the present invention, the mounting portion of the deodorizing cartridge is made rugged, and is excellent in durability.
