[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat device in which electrical components of a toilet bowl are housed in a casing, and more particularly to a mounting structure of a toilet seat and a toilet lid connected to the casing.

[0002]

2. Description of the Related Art A stool-type flush toilet is provided with a normal toilet seat directly on a toilet, and a so-called "multifunctional toilet seat" having a local washing function, a deodorizing function, a toilet seat heating function, etc. in a casing. In some cases, the casing of the toilet seat device is installed on a toilet bowl. The latter is a system in which a nozzle device for local washing, a heating water supply system for washing water, a deodorizing device, and a control unit therefor are provided in a casing, and the casing is fixed to a toilet body. With a structure attached.

[0003] These toilet seats and lids protrude the mounting seats at the left and right ends of the respective base ends to make holes in them.
In general, a structure in which the hole is connected to the casing by a hinge shaft through a hinge shaft is adopted.

On the other hand, a structure in which a resistance is applied to the rotation of the hinge mechanism when the toilet seat and the toilet lid close, and the operation is performed gently has been conventionally used. As such an opening / closing mechanism, there is a mechanism described in Japanese Patent Application Laid-Open No. 2-63424 and the like, in which an opening / closing unit for inserting a hinge shaft of a toilet seat and a toilet lid is installed in a casing.

[0005]

However, in the case where mounting seats are provided on the left and right sides of the base end of the toilet seat or the toilet lid and the mounting seats are pivotally attached to the casing by a hinge shaft as in the former, the hinge shaft is substantially orthogonal to the hinge shaft. It is necessary to provide a support seat for the hinge shaft in the casing. For this reason, when designing the casing, it is necessary to provide the casing with a shape that sandwiches both sides of the base end of the toilet seat or the toilet lid, which easily affects the degree of freedom in design.

An opening / closing unit having a built-in resistance mechanism has a larger bulk and a larger area occupied in a casing as compared with a case where only a hinge shaft is used. For this reason, the layout of the device incorporated in the casing is also hindered. In some cases, the casing needs to be increased in size, and there is a limit to downsizing.

[0007] As described above, when the toilet seat or the toilet lid is attached to the casing of the toilet seat device, the connection portion interferes with the space in the casing, and the effective range of the planar layout of the device is likely to be narrowed.

The problem to be solved in the present invention is to reduce the planar bulk occupied by the connecting portion of the toilet seat and the toilet lid in the casing of the toilet seat device, and to suppress interference with the planar layout of the equipment.

[0009]

SUMMARY OF THE INVENTION The present invention is directed to a toilet seat device in which electrical components of a toilet bowl are housed in a casing, and a toilet seat and a toilet lid are attached to the casing so as to be openable and closable. And the toilet seat
Opening / closing unit that provides resistance when the

The toilet chamber is housed in the hinge chamber with the axis down and the hinge axis of the toilet lid up.

[0010]

[Function] Opening / closing unit stored at the base end of toilet seat and toilet lid
The hinge shaft is overlapped below and above and connected to the casing side, so that the toilet seat and toilet lid including these opening / closing units
Hinge chamber for housing the base end portion may be provided only in one place on the front side of the casing. For this reason, compared to connecting the left and right ends of the base end of the toilet seat and the toilet lid to the casing, the planar bulk occupied by the hinge chamber is reduced. Therefore, the opening / closing unit is included at the base end.
However, even in the case of the above, the area for appreciating the planar layout of the devices housed in the casing becomes narrower, and the devices can be installed with an effective layout range secured.

FIG. 1 is a perspective view of a toilet seat apparatus having a toilet seat and a toilet lid mounting structure of the present invention installed on a toilet body. In this embodiment, a sanitary washing device for local washing will be described as an example of a toilet seat device.

In the figure, a toilet body 50 is provided with a casing 2 of a sanitary washing device 1 by using an upper surface of a rim on a back side thereof.
The toilet seat 3 and the toilet lid 4 are respectively attached to the casing 2 so as to be freely opened and closed.

The sanitary washing device 1 is a water supply heating system for heating and supplying washing water to the inside thereof. In use, the nozzle device dives under the toilet seat 3 to advance to the ball portion of the toilet body 50 to spray the washing water. And a controller for controlling each functional unit is incorporated, and a conventionally used one can be used as it is. The operation of the functional unit can be performed by a remote controller (not shown) hung on a wall, and an auxiliary operation panel 1 a is provided on a side portion of the casing 2.

FIG. 2 is a perspective view of the toilet seat 4 when the toilet lid 4 is opened. The toilet seat 3 and the toilet lid 4 have their base ends connected to the front side of the casing 2 and hinged to each other. The blocks are 3a and 4a.

FIG. 3 is a schematic exploded perspective view showing a connecting structure of the toilet seat 3 and the toilet lid 4 to the casing 2.

On the front surface of the casing 2, there is provided a hinge chamber 2a which accommodates the hinge blocks 3a and 4a and has a size allowing the rotation of the hinge blocks 3a and 4a.
On the inner walls at both ends in the frontage direction of the hinge chamber 2a,
A mounting groove 2b for detachably connecting a retainer block 5 for connecting both the toilet seat 3 and the toilet lid 4 to the casing 2 is formed in a vertical direction. Then, a slit 2c is opened in a lower end portion of the mounting groove 2b, thereby restraining the retainer block 5 in a detachable manner.

The hinge blocks 3a, 4a of the toilet seat 3 and the toilet lid 4, respectively, incorporate opening / closing units 6, 7 for applying resistance when the toilet seat 3 and the toilet lid 4 are closed so as to operate slowly. That is, in the conventional structure, such opening / closing units 6 and 7 are provided inside the casing 2 and the toilet seat 3 and the toilet lid 4 are connected to these via pins, whereas the toilet seat 3 and the toilet lid 4 themselves are connected to each other. Opening / closing units 6 and 7 are provided.

FIG. 4 is a front vertical sectional view showing a structure for connecting the toilet seat 3 to the opening / closing unit 6 and the casing 2.

A hinge shaft 3b having a circular cross section protruding outward is provided coaxially on one end surface of the hinge block 3a of the toilet seat 3 in the axial direction. Further, inside the hinge block 3a, a storage chamber 3c of the opening / closing unit 6 having an open end surface opposite to the hinge shaft 3b is formed.

The opening / closing unit 6 has a housing 6a provided with a resistance mechanism or the like inside as an outer shell, which is
c, and is fixed to a hinge shaft 8 extending coaxially with the hinge shaft 3b. For the internal resistance mechanism, for example, the one proposed by the applicant of the present invention and filed as Japanese Utility Model Application No. 2-128339 can be used as it is, and will be briefly described below.

As a resistance mechanism, a rotatable rotor 6b and a coil spring 6c arranged coaxially therewith are provided inside the housing 6a. The rotor 6b is a cylindrical body having one end opened, and has an outer diameter that is fitted into the housing 6a and is rotatable. A viscous agent V such as grease is sealed between the housing 6a and the outer peripheral surface of the rotor 6b. When the rotor 6b rotates in the housing 6a, the viscous resistance of the viscous agent V reduces the rotor 6b.
Act on.

The resistance of the rotor 6b and the coil spring 6c is determined by the joint 6 connecting the hinge shaft 8 to the resistance mechanism.
Finally, a cam 6e is connected to the joint 6d to maintain this standing posture when the toilet seat 3 is erected. In order to apply resistance by the coil spring 6c to the joint 6d, a transmitter 6f is rotatably provided coaxially inside the rotor 6b. A coil spring 6c is engaged with a substantially middle portion of the transmission element 6f in the axial direction, and further connects the transmission element 6f to a clutch mechanism.

A clutch spring 6g for interlocking and non-interlocking the transmission 6f with the rotor 6b.
And a shoe 6h. Clutch spring 6
One end of g is inserted into the peripheral wall portion of the transmission 6f, and the clutch spring 6g and the transmission 6f are connected. The shoe 6h is positioned and fixed on the bottom side of the rotor 6b, and rotates integrally with the rotor 6b. The clutch spring 6g is housed inside the shoe 6h, with the outer periphery facing the inner peripheral wall of the shoe 6h and the inner periphery facing the outer periphery of the transmitter 6f.

The direction in which the clutch spring 6g is wound is such that when the transmitter 6f rotates to the side where the toilet seat 3 closes, the diameter increases with this rotation, and conversely, when the transmitter 6f stands up, the diameter contracts. As a result, when the toilet seat 3 is raised, the clutch spring 6g is wound around the outer peripheral surface of the transmitter 6f, separates from the inner periphery of the shoe 6h, and the shoe 6h and the transmitter 6f become unrelated. When the toilet seat 3 rotates in the falling direction, the clutch spring 6g
The outer diameter of the shoe 6 increases as shown in the figure.
It is fitted by hitting the inner periphery of h. For this reason, the clutch spring 6g comes to be linked with the rotor 6b side,
The transmitter 6f rotates integrally with the rotor 6b, and the viscous resistance of the viscous agent V acts on the transmitter 6f.

With such a structure of the opening / closing unit 6,
When the toilet seat 3 is raised, no resistance acts on the toilet seat 3 and the toilet seat 3 can be opened with a light force. When the toilet seat 3 is closed, the rotation speed of the transmission element 6f is reduced by the resistance mechanism, and the opening / closing unit 6 with respect to the hinge shaft 8 connected thereto is opened. The rotation can also be reduced.

The hinge shaft 8, which is integrally fixed to the casing 2 after it is assembled into the casing 2, is connected integrally by inserting one end of the hinge shaft 8 into the transmitter 6f.
The portion protruding from has a square cross-sectional shape.

Returning to FIG. 3, the opening / closing unit 7 for the toilet lid 4
The structure of the toilet seat 3 is exactly the same as that of the toilet seat 3. A hinge shaft 4b is projected in the hinge block 4a in the axial direction, and a hinge shaft 9 is projected from the opening / closing unit 7 so as to be coaxial with the hinge shaft 4b.

A pair of retainer blocks 5 for connecting the toilet seat 3 and the toilet lid 4 to the casing 2 are provided at their lower ends with elastically deformable claws 5a. Retainer block 5
Is inserted into the mounting groove 2b from above.
Fit into the slit 2 c and are restrained, so that the retainer block 5 can be fixed integrally to the casing 2.

Further, in one of the retainer blocks 5, support holes 5b, 5c for inserting the hinge shaft 3b of the toilet seat 3 and the hinge shaft 4b of the toilet lid 4 to rotatably support them.
Is provided. The other retainer block 5 is provided with fixing holes 5d and 5e for fitting the hinge shafts 8 and 9 protruding from the respective opening and closing units 6 and 7 for the toilet seat 3 and the toilet lid 4 and fixing them. The fixing holes 5d and 5e have a rectangular opening cross section similarly to the hinge shafts 8 and 9, and when the hinge shafts 8 and 9 are fitted, the hinge shafts 8 and 9 are positioned with respect to the retainer block 5 around their axes. Cannot be changed. Therefore, when the toilet seat 3 and the toilet lid 4 are integrated with the casing 2 by the retainer block 5, the hinge shafts 8, 9 remain stationary, and the opening / closing units 6, 7 rotate around them.

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

First, the hinge shafts 8, 9 are inserted into the respective opening / closing units 6, 7 of the toilet seat 3 and the toilet lid 4, and these are connected to the internal resistance mechanism. Next, the other hinge shafts 3b, 4b of the toilet seat 3 and the toilet lid 4 are respectively inserted into the support holes 5b, 5c of the one retainer block 5, and the hinge shafts 8, 9 of the opening / closing units 6, 7 are fixed to the fixing holes 5d. , 5
e. As a result, the toilet seat 3 and the toilet lid 4 are integrated by the two retainer blocks 5, and the hinge block 3a of the toilet seat 3 extends downward and the hinge block 4a of the toilet lid 4
Are combined as an upper two-stage arrangement.

Further, as shown in FIG. 3, the left and right retainer blocks 5 and the hinge blocks 3a, 4a are connected to the hinge chamber 2.
a into the mounting groove 2b.
Fit inside. When the retainer block 5 is pushed all the way down, the claw 5a simultaneously enters and engages with the slit 2c, and the retainer block 5 is firmly fixed in the hinge chamber 2a.

By the above assembly, the toilet seat 3 and the toilet lid 4 are connected to the casing 2 at the same time. When the toilet seat 3 and the toilet lid 4 are opened, they can be lifted and raised by a light operation without receiving any resistance. At this time, the hinge shafts 8 and 9 are
The hinge shafts 8 and 9 do not rotate, and the opening / closing units 6 and 7 rotate around them to change the posture of the toilet seat 3 and the toilet lid 4. become.

When closing the toilet seat 3 from its upright position, it is only necessary to lightly push the tip of the toilet seat 3. As a result, the opening / closing unit 6 of the toilet seat 3 rotates around the stationary hinge shaft 8 and gently rests on the upper surface of the rim of the toilet body 50 while receiving resistance from the internal structure described in FIG. Stop. The same applies when the toilet lid 4 is closed. When the toilet seat 3 and the toilet lid 4 are closed together, the state returns to the closed state gently while receiving resistance from the respective opening / closing units 6 and 7.

As described above, the opening / closing units 6 and 7 are incorporated into the hinge blocks 3a and 4a at the base ends of the toilet seat 3 and the toilet lid 4, respectively, and are connected to the casing 2 via the retainer block 5. It is not necessary to incorporate an opening / closing unit in the casing 2. For this reason, the layout of the functional unit in the casing 2 is not hindered. Since the hinge blocks 3a and 4a are arranged to overlap each other in the vertical direction, the width of the hinge chamber 2a in the width direction can be small. Therefore, the planar volume of the hinge chamber 2a occupied in the casing 2 can also be suppressed, the degree of freedom in the layout of the built-in function unit can be improved, and other additional functions can be expanded.

Since the hinge blocks 3a, 4a are disposed in the hinge chamber 2a as shown in FIG. 2, even when the toilet seat 3 or the toilet lid 4 is opened, the hinge shafts 8, 9 are provided.
Etc. are not exposed. For this reason, the appearance can be improved, and a compact feeling can be given as a whole.

Further, in the case of maintenance inspection or replacement of parts, the toilet seat 3 and the toilet lid 4 are erected, and the claw 5a of the retainer block 5 is pushed in from the slit 2c to easily mount the retainer block 5. It can be removed from the groove 2b. For this reason, the toilet seat 3 and the toilet lid 4 can be disassembled without disassembling the casing 2, and work can be performed safely without exposing the device inside the casing 2 to the outside.

In the embodiment, the toilet seat 3 and the toilet lid 4 are connected to the casing 2 via the opening / closing units 6 and 7 having a built-in resistance mechanism, but the opening / closing units 6 and 7 are not provided. Can also. In this case, a hinge shaft having a circular cross section may be provided at both ends of the hinge blocks 3a and 4a so as to protrude therefrom, and the hinge shaft may be rotatably inserted into the retainer block 5.

The toilet seat device is not limited to the sanitary washing device of the present embodiment, but may be any of various types of devices provided with toilet electrical components in a casing.
