PURPOSE:To enable the loading of a toilet seat and lid on or unloading thereof from a casing of a hygienic cleaning device by a single action. CONSTITUTION:In a hygienic cleaning apparatus in which a functioning section for local cleaning is housed into a casing and a toilet seat and lid are mounted thereon, the toilet seat 3 and lid 4 are arranged successively on a retainer block 5 which provides a center point of rotation supporting them free to oscillate and the retainer block is assemlbed on the side of the surface of the casing free to load or unload. This eliminates the need for a structure of supporting a pivot shaft or the like of the toilet seat 3 and lid 4 rotatable on the side of the easing and thus enables the mounting of the toilet seat 3 and lid 4 on or removing thereof from the side of the easing simply by loading or unloading the retainer block 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat device having an electric component in a casing, and more particularly to a structure in which a toilet seat and a toilet lid connected to the casing can be easily attached and detached.

[0002]

2. Description of the Related Art Stool-type flush toilets are provided with a normal toilet seat directly on the toilet bowl and a "multi-functional toilet seat" with a local cleaning function, a deodorizing function and a toilet seat heating function in the casing. There are some cases where this casing is installed in a toilet bowl and used. The latter is a system in which a nozzle device for local cleaning, a heating supply system for cleaning water, a deodorizing device and its control unit are provided in a casing, and the casing is fixed to the toilet body. It has an attached structure.

For these toilet seats and lids, mounting seats are projected at the left and right ends of their respective base ends to make holes in them.
A structure in which a hinge shaft is connected to the casing by being pivotally attached to the hole is generally adopted.

In order to connect the toilet seat and the toilet lid to the casing by such a hinge shaft, the toilet seat and the toilet seat mounting seat are arranged to overlap each other, and the casing has a shape to sandwich these left and right mounting seats. After the hinge shaft is inserted, it is incorporated into the toilet seat or the seat of the toilet lid by elastic engagement or caulking so that it cannot be easily removed.

[0005]

Since the toilet seat and the toilet lid are members on which a person sits and are exposed to dust, the toilet seat and the toilet lid are easily soiled, and water splashes and the like often adhere to the toilet seat. Therefore, when cleaning the toilet seat or the toilet lid, it is difficult to work with the toilet seat or the toilet lid still connected to the casing, and it is necessary to remove the toilet seat or the toilet lid.

However, in the structure in which the hinge shaft is passed through the mounting seat and is connected to the casing, a tool such as a screwdriver is required when the hinge shaft is removed. For this reason, ordinary housewives are not accustomed to handling tools,
Even if I try to clean it, I often can't pull out the hinge shaft and end up as it is.

If the hinge shaft is forcibly pulled out,
There is a high possibility that the member for elastic engagement or caulking or the surface shape will be impaired. Therefore, even if an attempt is made to connect the toilet seat and the toilet lid to the casing again, the hinge shaft loses its function, resulting in looseness or the like during the opening / closing operation of the toilet seat or the toilet lid.

As described above, in the conventional structure for connecting the toilet seat and the toilet lid to the casing using the hinge shaft, the toilet seat and the toilet lid cannot be easily removed or connected from the casing, and cleaning of these members is not possible. There is a problem that it tends to be insufficient.

An object of the present invention is to make it possible to easily attach / detach the toilet seat and the toilet lid to / from the casing of the sanitary washing device with one touch.

[0010]

DISCLOSURE OF THE INVENTION The present invention is a toilet seat device in which electrical components are housed inside a casing, and a toilet seat is attached to the casing so that the toilet seat can be opened and closed.
It is characterized in that a retainer block for swingably supporting the toilet seat is connected to the base end portion as a rotation center, and the retainer block is detachably connected to the front surface side of the casing.

If the toilet seat is provided with a toilet lid in addition to the toilet seat, the base end of the toilet lid is connected to the retainer block in the same relationship as the toilet seat, and the toilet seat and the toilet lid are connected via the retainer block. It may be configured such that they are integrated and connected to the casing.

[0012]

Since the retainer block, which is connected to the base ends of the toilet seat and the toilet lid, is supported as a fulcrum of rotation, the structure for rotatably supporting the toilet seat and the toilet lid on the casing side is not necessary at all. .. The casing only needs to be provided with places and spaces where the retainer block can be fixed in a stationary state.If the place and space are connected to the retainer block by a detachable relationship, the toilet seat and the toilet lid will be attached to the retainer block. The casing can be indirectly incorporated into the casing as a detachable member. Therefore, by attaching / detaching the retainer block to / from the casing, it becomes possible to easily attach / detach the toilet seat or the toilet lid to / from the casing.

At both left and right ends of a, hinge shafts 3b having a circular cross section are provided so as to be coaxial with each other and project toward the frontage direction.
The hinge block 4a of the toilet lid 4 is also provided with hinge shafts 4b at both left and right ends thereof. The hinge shaft 4b and its surroundings are hidden by the upper surface of the toilet lid 4.

A pair of retainer blocks 5 for connecting the toilet seat 3 and the toilet lid 4 to the casing 2 are fitted and fixed in the mounting groove of the hinge chamber 2a except for the upper end portions thereof. The retainer block 5 has a cross-sectional shape that fits tightly into the wedge-shaped cross-section opening of the mounting groove 2b, and after fitting, is fixed in the mounting groove 2b with the front direction being restricted.

The retainer block 5 is provided with support holes 5a and 5b for vertically inserting the hinge shaft 3b of the toilet seat 3 and the hinge shaft 4b of the toilet lid 4 and rotatably supporting them. Then, an auxiliary hole 5c is opened between the support holes 5a and 5b, and the lock piece 5d is raised upward from the opening edge as shown in FIG. This lock piece 5d
Has a substantially hemispherical projection 5e fitted in the engagement groove 2c of the mounting groove 2b at its upper end, and is elastically deformable around the base end portion of the opening edge of the auxiliary hole 5c. is there.

FIG. 5 is a front vertical sectional view showing a main part when the toilet seat 3 and the toilet lid 4 are connected to the casing 2, and FIG. 6 is a sectional view taken along the line AA of FIG.

Hinge shafts 3 of the toilet seat 3 and the toilet lid 4, respectively
b and 4b are rotatably integrated with the support holes 5a and 5b of the retainer block 5 and are connected to the casing 2 by dropping the integrated body into the hinge chamber 2a. The retainer block 5 is inserted into the mounting groove 2b, and when the lower end of the retainer block 5 hits the bottom surface of the mounting groove 2b and stops, the protrusion 5 of the lock piece 5d.
The dimensional relationship is such that e fits into the engagement groove 2c.

In the above structure, the toilet seat 3 and the toilet lid 4 are assembled into the casing 2 in the following manner.

As described above, the hinge shafts 3b and 4b of the toilet seat 3 and the toilet lid 4 are inserted into the support holes 5a and 5b so that the retainer block 5 is integrated with both ends of the hinge blocks 3a and 4a.

Then, when the retainer block 5 is dropped into the mounting groove 2b of the hinge chamber 2a, the lower end of the retainer block 5 is seated on the bottom surface of the mounting groove 2b and stopped. At the same time, the protrusion 5 is formed on the inner wall of the mounting groove 2b.
The lock piece 5d, which was hit by e and bent toward the center of the hinge chamber 2a, is restored to its original shape as shown in FIG. 5 by fitting the protrusion 5e into the engagement groove 2c. Therefore, the protrusion 5e is constrained in the engagement groove 2c, and the retainer block 5 is fixed by determining its vertical position.

Due to such assembling, the retainer block 5 is restrained in the frontage direction by the wedge-shaped opening cross-sectional shape of the mounting groove 2b, and is also restrained in the vertical direction by the lock piece 5d and the engaging groove 2c. Therefore, it is possible to set the toilet seat 3 and the toilet lid 4 to the correct positions and connect them to the casing 2 simply by dropping the retainer block 5 integrated with the toilet seat 3 and the toilet lid 4 into the hinge chamber 2a. it can.

On the other hand, when the toilet seat 3 and the toilet lid 4 are removed from the casing 2, they are integrally pulled up. As a result, the protrusion 5e of the lock piece 5d having a hemispherical surface is forcibly pulled out from the engagement groove 2c, and the protrusion 5e rides on the inner wall of the mounting groove 2b. Therefore, the lock piece 5d
The lock piece 5d is elastically deformed so as to bend slightly toward the center of the hinge chamber 2a. Therefore, when the toilet seat 3 and the toilet lid 4 are further pulled up, the retainer block 5 moves upward in the mounting groove 2b and can be finally removed.

As described above, the toilet seat 3 and the toilet lid 4 can be easily removed from the casing 2 simply by pulling up the connecting portion with the casing 2 by integrating them. Therefore, even when the toilet seat 3, the toilet lid 4, and the casing 2 are wiped and cleaned, they can be easily disassembled, the corners can be easily cleaned, and the cleanliness can be always maintained.

Further, in the case where the casing 2 is provided with a hole through which the hinge shaft or the like is passed as in the conventional case, water or the like is likely to enter through the gap between the holes. On the other hand, since only the hinge chamber 2a is provided in the casing 2, the airtightness is improved, and it is possible to prevent equipment from being exposed to water and accidents due to this.

Furthermore, without disassembling the casing 2,
The toilet seat 3 and the toilet lid 4 can be disassembled, and the electric work inside the casing 2 can be safely carried out without exposing it to the outside.

In the illustrated example, hinge shafts 3b and 4b are provided on the toilet seat 3 and the toilet lid 4, respectively, and these are rotatably inserted into the support holes 5a and 5b of the retainer block 5. Instead of this, holes having circular opening cross sections are provided in both end faces of the hinge blocks 3a and 4a, and projections having circular cross sections which fit into these holes are provided in the retainer block 5 so that the projections can be inserted. You can

FIG. 7 is a schematic perspective view of an essential part showing another connecting structure between the hinge chamber 2a and the retainer block 5, and FIG.
9 is a front vertical cross-sectional view showing a connecting structure to the casing 2, FIG.
FIG. 9 is a vertical sectional view taken along the line BB of FIG.

On the inner walls of both ends of the hinge chamber 2a in the front direction, holding seats 2d of the retainer block 5 whose front side is open are provided. This holding seat 2d is used for the retainer block 5
Surface 2e with a profile that matches the shape of the back of the
And a support surface 2f which is formed at the lower end of the retainer block 5 and on which the lower end of the retainer block 5 can be placed obliquely above and from the front. When the lower end portion of the retainer block 5 is placed on the support surface 2f, the retainer block 5 is moved to the position shown in FIG.
The curved surface is formed so that it can turn in the direction indicated by the one-dot chain line arrow.

Further, guide grooves 2g are provided on the inner walls at both ends in the frontage direction of the hinge chamber 2a to serve as guides for attaching and detaching the retainer block 5, and a small engaging protrusion 2h is provided at the end of the guide groove 2g. Set up.

On the other hand, the retainer block 5 is provided with support holes 5a and 5b for rotatably supporting the hinge shafts 3b and 4b of the toilet seat 3 and the toilet lid 4 in the same manner as the above example.
The lower end surface of the retainer block 5 has a circular shape slightly smaller than the outer diameter drawn by the support surface 2f of the holding seat 2d. When the retainer block 5 is mounted on the support surface 2f, the retainer block 5 rotates its lower end portion as described above. It is possible to turn around the center. Further, on the surface of the retainer block 5 facing outward, a pin 5f inserted into the guide groove 2g is provided so as to project.
The pin 5f has an outer diameter and an axial length such that the pin 5f can freely move in the guide groove 2g, and after exceeding the engaging protrusion 2h provided at the end portion of the guide groove 2g, the engaging protrusion 2h.
Shall be bound by

Even in the case of this structure, the hinge shafts 3b and 4b of the toilet seat 3 and the toilet lid 4 are inserted into the support holes 5a and 5b of the retainer block 5 to be integrated beforehand. And
As shown in FIG. 10, the retainer block 5 is placed so that it can be inserted into the hinge chamber 2a from diagonally above and the lower end portion of the retainer block 5 is supported by the supporting surface 2f of the holding seat 2d.
Place it on the top and place it temporarily. By thus recessing the support surface 2f of the holding seat 2d, it can be used for positioning when the retainer block 5 is assembled, and the retainer block 5 can be used.
Even if they are hidden by the toilet lid 4, they can work easily.

When the retainer block 5 having its lower end placed on the support surface 2f is moved in the direction in which the toilet seat 3 and the toilet lid 4 are erected, the retainer block 5 gradually rises in the direction shown by the arrow in FIG. 10, and the pin 5f is placed in the guide groove 2g. Get in. Therefore, the bottom surface of the retainer block 5 is rotatably supported by the support surface 2f, and the upper end side is constrained by the guide groove 2g via the pin 5f. Therefore, the retainer block 5 turns without floating from the support surface 2f, and finally the back surface portion thereof comes into contact with the receiving surface 2e of the holding seat 2d and stops. Then, at this time, the pin 5f is engaged with the engaging projection 2
The retainer block 5 stands still at a position exceeding h, and the retainer block 5 is restrained from swinging in the front-rear direction by the restraint by the engagement protrusion 2h.

As described above, the retainer block 5 can be inserted into the holding seat 2d of the hinge chamber 2a by simply dropping the retainer block 5 into the end portion of the guide groove 2g.
Restrained and supported by the receiving surface 2e and the supporting surface 2f, the toilet seat 3 and the toilet lid 4 can be connected to the casing 2.

In addition, when the toilet lid 4 is erected, as shown in FIG.
As shown in FIG. 1, the upper surface near the base end hits the corner of the casing 2. At this time, the portion that abuts the casing 2 serves as a fulcrum, and an upward component force F acts on the hinge shaft 4b as shown in the figure. The component force F acts so as to pull the retainer block 5 upward from the holding seat 2d, and becomes an external force that pulls out the retainer block 5 from the casing 2.

On the other hand, since the retainer block 5 has its pin 5f inserted in the guide groove 2g, even if it is attempted to move upward, this is caused by the engaging force between these pin 5f and the guide groove 2g. Stop. Therefore, toilet seat 4
Even if the retainer block 5 is erected, the action of pulling out the retainer block 5 is canceled out, and the retainer block 5 is stably held by the seat 2d.
Can be kept inside. Therefore, even if the toilet seat 3 is opened and closed while the toilet lid 4 is upright, there is no rattling in its operation.

The guide groove 2g is provided in the retainer block 5
Since it is provided in conformity with the locus of the circle drawn by the pin 5f when turning, the retainer block 5 is pulled out not only when the toilet lid 4 is erected but also when the toilet seat 3 and the toilet lid 4 are opened. The acting force is blocked. Therefore, the retainer block 5 is fixed by fixing means such as screws.
Even if the seat is not fixed to the casing 2, the stable opening / closing operation of the toilet seat 3 and the toilet lid 4 is maintained.

Furthermore, in order to remove the toilet seat 3 and the toilet lid 4 from the casing 2, the toilet seat 3 and the toilet lid 4 are simultaneously pulled toward you. As a result, the pin 5f can be moved forward in the guide groove 2g by shaking off the restraint by the engaging projection 2h, and at the same time, the retainer block 5 is rotated about its bottom surface as a turning center. And finally pin 5
f is disengaged from the guide groove 2g, and then the retainer block 5 is extracted from the hinge chamber 2a.
The toilet seat 3 and the toilet lid 4 can be separated from each other. In this way, the toilet seat 3 and the toilet lid 4 can be easily attached / detached to / from the casing 2 by a one-touch method, and no tools or the like are required at all, and work can be performed without damaging members.

Although the hinge shafts 3b and 4b are provided at the base end portions of the toilet seat 3 and the toilet lid 4 in the embodiment, they are given resistance when the toilet seat 3 and the toilet lid 4 are closed so that the toilet seat 3 and the toilet lid 4 are gently closed. Even when using the opening and closing unit that is made to operate,
Of course, the configuration of the present invention can be applied. Further, the toilet seat device is not limited to the sanitary washing device of the present embodiment, but may be various devices having a toilet electric component in the casing.

[0045]

According to the present invention, the toilet seat or a combination of the toilet seat and the toilet lid can be attached to and detached from the casing with one touch without disassembling the casing or removing the hinge shaft. For this reason, it is possible to easily perform the work without using a tool or the like, and the member is not damaged.
Also, without opening or disassembling the casing,
Since the toilet seat and the toilet lid can be attached and detached, the functional portion of the toilet seat device is not damaged.
