Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a toilet seat device in which a toilet bowl electrical component is housed inside a casing, and more particularly to a mounting structure for a toilet seat and a toilet lid connected to the casing.

[0002]

[Prior Art]

 The stool-type flush toilet is equipped with a regular toilet seat directly on the toilet bowl, and is also called a "multifunctional toilet seat" and has a local cleaning function, deodorizing function, toilet seat heating function, etc. inside the casing. There is one that is installed and used on the toilet bowl. The latter is a system in which a nozzle device for local cleaning, a heating supply system for cleaning water, a deodorizing device, and their control unit are provided in a casing, and this casing is fixed to the toilet body. It has a structure with and attached.

These toilet seats and lids have a structure in which they are connected by protruding mounting seats at both left and right ends of their respective base ends, making holes in these seats, and pivoting them to the casing through a hinge shaft through these holes. Generally 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 are closed so that the hinge mechanism operates gently has been conventionally used. An example of such an opening / closing mechanism is disclosed in Japanese Patent Laid-Open No. 2-63424, in which an opening / closing unit for inserting the hinge shafts of the toilet seat and the toilet lid is installed in the casing. It is a thing.

[0005]

[Problems to be solved by the device]

 However, in the former case where mounting seats are provided on the left and right sides of the base end of the toilet seat or toilet lid and are pivotally attached to the casing by the hinge shaft, the supporting seat for the hinge shaft is installed in a direction almost orthogonal to the hinge shaft. Need to be installed inside. For this reason, when designing the casing, it is necessary to give the casing a shape that sandwiches both sides of the base end of the toilet seat or toilet lid, and this tends to affect the degree of freedom in design.

Further, the opening / closing unit having a built-in resistance mechanism is bulkier than the case where only the hinge shaft is used, and occupies a large area in the casing. For this reason, the layout of the equipment incorporated in the casing is also impeded, and in some cases it is necessary to increase the size of the casing, which limits the compactness.

As described above, when the toilet seat or the toilet lid is attached to the casing of the toilet seat device, the connecting portion interferes with the space in the casing, and the effective range of the plane layout of the device tends to be narrowed.

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

[0009]

[Means for Solving the Problems]

 The present invention relates to a toilet seat device in which a toilet bowl electrical component is housed inside a casing, and a toilet seat and a toilet lid are attached to the casing so that the toilet seat and the toilet lid can be opened and closed, respectively. A hinge shaft having an axis line in the front direction is provided at a position distant from the edge of the portion, and both ends of the hinge shaft having a size capable of accommodating the base end portion are provided on the front surface side of the casing. A hinge chamber that can be supported is provided so as to be recessed inward, and the hinge chamber is accommodated in the hinge chamber with the base end of the toilet seat facing downward and the base end of the toilet lid facing upward.

[0010]

[Action]

 Since the base ends of the toilet seat and the toilet lid are connected to the casing side by overlapping the bottom and the top with each other, the hinge chamber for accommodating these base ends only needs to be provided at one position on the front side of the casing. Therefore, the planar volume occupied by the hinge chamber is smaller than that in the case of connecting the two left and right ends of the base end of the toilet seat and the toilet lid to the casing side. Therefore, the area that interferes with the planar layout of the equipment housed in the casing is also narrowed, and the equipment can be installed with the effective layout range secured.

【Example】

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

In the figure, the casing 2 of the sanitary washing device 1 is fixed to the toilet body 50 by utilizing the upper surface of the rim on the back side thereof, and the toilet seat 3 and the toilet lid 4 are opened and closed on the casing 2, respectively. It is attached freely.

The sanitary washing device 1 is a water supply heating system for heating and supplying washing water into the sanitary washing device 1, and when used, dives under the toilet seat 3 and advances to the ball portion of the toilet body 50 to inject the washing water. It incorporates a nozzle device and a controller that controls each functional unit, and the ones that have been conventionally used can be used as they are. The operation of the functional unit can be performed by a remote controller (not shown) mounted on the wall, and the side of the casing 2 is provided with the auxiliary operation panel 1a.

FIG. 2 is a perspective view when the toilet lid 4 is opened. The toilet seat 3 and the toilet lid 4 are connected to the front side of the casing 2 at the center of their respective base end portions, and the connection portions thereof are hinged. 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 with respect 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 rotational movements of the hinge blocks 3a and 4a. 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 vertically formed on the inner walls of both ends of the hinge chamber 2a in the front direction. Then, a slit 2c is opened at the lower end portion of the mounting groove 2b, whereby the retainer block 5 is detachably restrained.

The hinge blocks 3a and 4a of the toilet seat 3 and the toilet lid 4 respectively incorporate opening / closing units 6 and 7 for giving a resistance when the toilet seat 3 and the toilet lid 4 are closed so as to operate gently. 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. Opening / closing units 6 and 7 are provided.

FIG. 4 is a front vertical cross-sectional view showing the connecting structure of 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 coaxially provided 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 opposite to the hinge shaft 3b is formed.

The opening / closing unit 6 has a housing 6a having a resistance mechanism and the like inside as an outer shell, and this is assembled and fixed in the storage chamber 3c, and the hinge shaft 8 extending in the opposite direction to the hinge shaft 3b is coaxial. Prepared above. As the internal resistance mechanism, for example, the structure of the applicant previously proposed and filed as Japanese Patent 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 with the rotor are provided inside the housing 6a. The rotor 6b is a cylindrical body with one end open, and its outer diameter is such that it fits tightly into the housing 6a and is rotatable. Further, a viscous agent V such as grease is sealed between the housing 6a and the outer peripheral surface of the rotor 6b, and when the rotor 6b rotates in the housing 6a, the viscous resistance of the viscous agent V is applied to the rotor 6b. To work.

The resistance caused by the rotor 6b and the coil spring 6c finally exerts an acting force on the joint 6d connecting the hinge shaft 8 to the resistance mechanism, and when the toilet seat 3 is erected on the joint 6d. A cam 6e for maintaining this standing posture is connected. In order to give resistance to the joint 6d by the coil spring 6c, a transmitter 6f is rotatably provided coaxially inside the rotor 6b. A coil spring 6c is engaged with the intermediate portion of the transmission element 6f in the axial direction, and the transmission element 6f is connected to the clutch mechanism.

A clutch spring 6g and a shoe 6h for interlocking and non-interlocking with the rotor 6b are incorporated in the transmitter 6f. One end of the clutch spring 6g is inserted into the peripheral wall portion of the transmission element 6f, and the clutch spring 6g and the transmission element 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, the outer periphery of which faces the inner peripheral wall of the shoe 6h and the inner periphery of which faces the outer periphery of the transmitter 6f.

The winding direction of the clutch spring 6g is such that when the transmitter 6f rotates toward the side where the toilet seat 3 is closed, the diameter increases with this rotation, and conversely, when it rises, the diameter contracts. As a result, when the toilet seat 3 is erected, the clutch spring 6g is wound around the outer peripheral surface of the transmitter 6f and separated from the inner periphery of the shoe 6h, so that the shoe 6h and the transmitter 6f are free from each other. Also, when the toilet seat 3 rotates in the direction of falling, the diameter of the clutch spring 6g increases, and the outer peripheral surface hits the inner periphery of the shoe 6h and fits as shown in the figure. Therefore, the clutch spring 6g is interlocked with the rotor 6b side, the transmitter 6f rotates together 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 erected, no resistance acts and it can be opened with a light force. When the toilet seat 3 is closed, the rotation speed of the transmission member 6f is slowed by the resistance mechanism. Therefore, the rotation of the opening / closing unit 6 with respect to the hinge shaft 8 connected thereto can also be decelerated.

Further, the hinge shaft 8 which is integrally fixed to the casing 2 after being incorporated into the casing 2 is integrally coupled by inserting one end thereof into the transmitter 6f, and the portion protruding from the housing 6a has a quadrangular cross-sectional shape. have.

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

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

Further, one retainer block 5 is provided with 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. The other retainer block 5 is provided with fixing holes 5d and 5e for fitting the hinge shafts 8 and 9 protruding from the opening / closing units 6 and 7 for the toilet seat 3 and the toilet lid 4, respectively, and fixing them. Like the hinge shafts 8 and 9, the fixing holes 5d and 5e have a square opening cross section, and when the hinge shafts 8 and 9 are fitted, the hinge shafts 8 and 9 are attached to the retainer block 5 about their axes. You cannot change your posture. 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 and 9 remain stationary, and the opening / closing units 6 and 7 rotate around them. Become.

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

First, the hinge shafts 8 and 9 are inserted into the opening / closing units 6 and 7 of the toilet seat 3 and the toilet lid 4, respectively, and these are connected to the internal resistance mechanism. Next, insert the other hinge shafts 3b and 4b of the toilet seat 3 and the toilet lid 4 into the support holes 5b and 5c of the one retainer block 5, respectively, and at the same time, fix the hinge shafts 8 and 9 of the opening / closing units 6 and 7. Fit into the holes 5d and 5e. 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 is arranged on the lower side and the hinge block 4a of the toilet lid 4 is arranged on the upper side. Can be combined.

Further, as shown in FIG. 3, the left and right retainer blocks 5 and the hinge blocks 3a and 4a are dropped into the hinge chamber 2a, and the retainer block 5 is fitted into the mounting groove 2b. Then, when the retainer block 5 is pushed all the way down, at the same time, the pawls 5a enter the slits 2c and engage with each other, 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 simultaneously connected to the casing 2. When the toilet seat 3 and the toilet lid 4 are opened, they can be lifted and stood up by a light operation without receiving any resistance. At this time, since the hinge shafts 8 and 9 are constrained by the fixing holes 5d and 5e of the retainer block 5, the hinge shafts 8 and 9 do not rotate, and the opening / closing units 6 and 7 rotate around them. The postures of the toilet seat 3 and the toilet lid 4 will change.

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

As described above, since the opening / closing units 6 and 7 are incorporated in the hinge blocks 3 a and 4 a at the base end portions 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 the opening / closing unit in the casing 2 as described above. Therefore, the layout of the functional parts in the casing 2 is not hindered. Further, since the hinge blocks 3a and 4a are arranged so as to be vertically overlapped with each other, the dimension in the width direction of the hinge chamber 2a can be small. Therefore, the planar size of the hinge chamber 2a occupying in the casing 2 can be suppressed, the degree of freedom in the layout of the functional units incorporated therein can be improved, and other additional functions can be expanded.

Further, since the hinge blocks 3a and 4a are arranged so as to be dropped into 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 and 9 are exposed. I won't. As a result, the appearance is improved and the overall feeling of compactness can be given.

Further, at the time of maintenance and inspection or replacement of parts, if the toilet seat 3 and the toilet lid 4 are erected and the claws 5a of the retainer block 5 are pushed in through the slits 2c, the retainer block 5 can be easily removed. It can be removed from the mounting groove 2b. Therefore, the toilet seat 3 and the toilet lid 4 can be disassembled without disassembling the casing 2, and the device inside the casing 2 can be safely operated without being exposed 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. You can also In this case, hinge shafts having a circular cross section may be provided so as to project at both ends of the hinge blocks 3a and 4a, and the hinge shafts may be rotatably inserted into the retainer block 5.

The toilet seat device is not limited to the sanitary washing device of this embodiment, and may be any device having a toilet electric component in the casing.
