DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a sanitary washing device having a local washing function.

[Conventional technology]

2. Description of the Related Art Conventionally, a sanitary washing device having a local washing function has been used as installed on, for example, a seated flush toilet bowl. FIG. 6 is a perspective view showing an example in which the sanitary washing device A is installed on the toilet body B. The sanitary washing device A is arranged in front of the wash water tank C, and a device such as a nozzle device is provided inside the casing 1. It is stored. The toilet seat 2 and the toilet lid 3 are attached to the casing 1 so as to be openable and closable by a hinge structure.

The toilet seat 2 and the toilet lid 3 are pivotally attached to the casing 1 so as to be rotatable independently of each other by a common hinge shaft.
The main part of the pivot structure is shown in FIG. As shown in the figure, a pair of mounting seats 2a and 3a are provided at both ends of the base end portions of the toilet seat 2 and the toilet lid 3, respectively, and mounting holes 2b and 3b are formed in them. Then, the hinge shaft 20 is inserted by aligning the cores of the mounting holes 2b and 3b, and the tip end of the hinge shaft 20 is fitted into the pivot hole 1a of the casing 1, whereby the toilet seat 2 and the toilet lid 3 are pivotally mounted so as to be openable and closable. . The tip of the hinge shaft 20 has a spherical shape with a slit 21 formed therein and can be fitted into the pivot hole 1a by utilizing the elastic deformation of the slit 21, and unless a tool or the like is used the casing. It is retained without dropping from 1.

[Problems to be solved by the device]

The sanitary washing device includes a heat exchanger, a valve unit, and the like in addition to a nozzle for local washing, and an operation panel, a control unit, and the like for operating these devices are arranged. Therefore, the casing 1 has a structure in which electric devices, a control board, and the like are arranged as they are exposed and wiring is provided. As described above, since the casing 1 accommodates the electric device and the like, it is necessary to ensure the seal. That is, considering that the sanitary washing device A itself is a device around water and there is a high possibility of breaking the water, it can be said that the seal structure is an essential condition.

By the way, in the structure for pivotally attaching the toilet seat 2 and the toilet lid 3 shown in FIG. 7, the pivot hole 1a into which the hinge shaft 20 is fitted is provided in the casing 1.
Open to. Therefore, if water around the hinge shaft 20 breaks, the water may penetrate the hinge shaft 20 and enter the inside of the casing 1.

In order to prevent such intrusion of water, a structure in which a cover 22 is provided inside the casing 1 is conventionally used as shown in the figure. This cover 22 is a casing
It is shielded so as not to reach the inside of the casing, and is integrated with the casing 1 as a separate member by welding or by screwing.

However, even if the cover 22 is provided, the pivot hole 1a can serve as a flow path for water that connects the inside and outside of the casing 1, so that infiltration of water cannot be prevented. Further, although the cover 22 can prevent water from entering the inner part of the casing 1, corrosion of the members due to the increase of internal humidity is inevitable.

Further, since the cover 22 is provided separately and is integrated with the casing 1, the number of parts and the number of assembling steps are increased, which is disadvantageous in terms of cost.

Therefore, an object of the present invention is to reliably prevent water from entering the casing with a simple hinge structure.

[Means for Solving the Problems]

In order to achieve the above object, the sanitary washing device of the present invention is provided with a device such as a nozzle for local washing, a control unit, etc. inside the casing, and a mounting seat provided at each base end of the toilet lid and toilet seat And the hinge shafts in the mounting holes opened in these mounting seats so that they can rotate relative to each other.
In a sanitary washing device in which the toilet lid and the toilet seat are pivotally attached to the casing in a freely openable and closable manner by the hinge shaft, the hinge shaft has a flange provided at one end thereof and a rod having an equal diameter section extending substantially coaxially from the flange. And a ridge that is an outer peripheral surface of the flange and has a tapered shape on the side facing the rod, and the rod of the hinge shaft can be fitted into the casing, and the surface of the casing A portion where the flange of the hinge shaft is housed is provided in the mounting seat on the side away from the pivotal mounting hole of the mounting seats that are overlapped in the width direction and provided with a pivotal mounting hole that is open only on the side. And a holding groove into which the protrusion is fitted.

〔Example〕

Hereinafter, the features of the present invention will be specifically described with reference to the embodiments shown in the drawings.

FIG. 1 is a vertical sectional view showing a main part of the sanitary washing device of the present invention,
FIG. 2 is a plan view of the sanitary washing device, and FIG. 3 is a side view. The same members as those shown in the conventional example are designated by common reference numerals, and detailed description thereof will be omitted.

As shown in FIG. 2, the casing 1 of the sanitary washing device A
Has an operation panel 4 at the left end, and forms a bulging portion 5 that protrudes to the front side so as to sandwich the respective mounting seats 2a and 3a of the toilet seat 2 and the toilet lid 3. Further, as shown in FIG. 4, pivot holes 5b are formed in the left and right facing surfaces 5a where the bulging portions 5 sandwich the mounting seats 2a and 3a. As shown in FIG. 1, the pivot hole 5b is formed as a concave portion which enters the inside of the casing 1 from the facing surface 5a, and the casing 1 is provided with a toilet seat 2 and a toilet lid 3 for attachment unlike the conventional example. No holes have been drilled.

As shown in FIG. 5, a hinge shaft 6 which pivotally mounts the toilet seat 2 and the toilet lid 3 on one axis has a flange 6a formed at one end, and a thin rod 6b is projected from this portion. Also,
On the peripheral surface of the flange 6a, a projection 6c is provided which is tapered so that the rod 6b side has a small diameter. A large-diameter receiving seat 3c for receiving the flange 6a and a small-diameter inserting hole 3d for inserting the rod 6b are provided in the mounting hole 3b of the toilet lid 3 through which the hinge shaft 6 is inserted, and further on the inner circumference of the receiving seat 3c. A holding groove 3e into which the protrusion 6c of the flange 6a is fitted is formed.

Here, when assembling the toilet seat 2 and the toilet lid 3 to the casing 1, first, the mounting seats 2a and 3a of the toilet seat 2 and the toilet lid 3 are overlapped as shown in FIG. 5, and the respective mounting holes 2b and 3b are attached. Temporarily align the cores. Then, the mounting seats 2a and 3a are set so as to fit between the left and right bulged portions 5 of the casing 1, and the hinge shaft 6 is inserted into the mounting holes 2b and 3b. The hinge shaft 6 is the first
As shown in the figure, the tip of the rod 6b enters the pivot hole 5b,
The ridge 6c of the flange 6a fits into the holding groove 3e of the seat 3c.

In the above assembly, if the distance between the outer end surfaces of the toilet seat 2 is set to be substantially equal to or slightly shorter than the distance between the facing surfaces 5a of the bulging portion 5, the toilet seat integrated with the casing 1 by the hinge shaft 6 2 and the toilet lid 3 are held without shifting to the left and right. Then, the hinge shaft 6 itself has the ridge 6c and the holding groove 3e.
The toilet seat 2 and the toilet lid 3 can be rotated around the hinge shaft 6 without coming off due to the engagement with.

Further, if the casing 1 and the hinge shaft 6 are made of synthetic resin, respectively, when the rod 6b of the hinge shaft 6 is fitted into the pivot hole 5b, they can be fixed by utilizing the elastic deformation of both. That is, if the rod 6b is inserted into the pivot hole 5b with a strong force, the rod 6b can be firmly fixed by elastic deformation of the pivot hole 5b. Therefore, when the toilet seat 2 or the toilet lid 3 is rotated, the hinge shaft 6 does not rotate together, and the toilet seat 2 and the toilet lid 3 can be independently rotated.

In the above configuration, since the casing 1 is not provided with holes for pivotally mounting the toilet seat 2 and the toilet lid 3, it is possible to prevent water from entering the casing 1 from the outside. Therefore, since there is no possibility of occurrence of an electric leakage accident in the built-in electric equipment or wiring, it can be used safely and internal corrosion can be avoided.

Further, the number of parts and the number of assembling steps are reduced as compared with the conventional case where a cover for preventing water from entering is separately provided and integrated with the casing so as to shield the hinge shaft portion. Therefore, it is also effective in reducing the cost of the product.

[Effect of device]

In the present invention, since the pivotal hole into which the hinge shaft is inserted is closed like a bag, water does not enter the casing and the built-in devices are protected completely. Compared with this, the number of parts and the number of assembling steps are reduced, and the cost can be improved.

Also, since the rod of the hinge shaft only needs to be a rod-shaped body having an equal diameter, the structure is simpler than the conventional one in which the tip is a sphere and the slit is provided, and the rod can be fitted into the pivot hole. It can be done more easily than using a spherical shape, and assembly and disassembly work is also easier.
