It is equipped with a jet nozzle for cleaning and an operation unit for performing operations.
[0009]
A toilet seat 30 and a toilet lid 40 are detachably attached to the casing main body 14 via a toilet seat toilet lid support mechanism 20. The toilet seat and lid support mechanism 20 includes a support mechanism 50 on the casing body 14 side and a supported mechanism 90 on the toilet seat 30 and the toilet lid 40 side. As shown in FIG. 2, the support mechanism 50 is provided in the support recesses 52 on both sides of the casing main body 14, and mainly includes a main body support portion 60 protruding in the axial direction on the support side surface 56 of the support recess 52. Configuration.
[0010]
The main body supporting portion 60 includes a sliding support base 62. The sliding supporting base 62 is formed of an opposing surface 64 and an outer surface 65. The outer surface 65 is perpendicular to the upper and lower arc surfaces 65a. It has an oval cross section defined by the surface 65b. A fixed protrusion 70 protrudes from the facing surface 64. The fixed protruding portion 70 has a shape obtained by reducing the size of the sliding support base 62. In addition, the main body support portion 60 is also provided on the corresponding support side surface of the opposite support recess (not shown), but since they have the same configuration, description thereof will be omitted.
[0011]
Next, the supported mechanism 90 provided on the toilet seat 30 and the toilet lid 40 will be described.
As shown in the cross-sectional view of FIG. 3 and the perspective view of FIG. 4, the supported mechanism 90 is provided on both sides of the ends of the toilet seat 30 and the toilet lid 40, and the support openings 32 formed in the ends of the toilet seat 30. It has. The support opening 32 has a diameter slightly larger than the vertical length of the arc surface 65a of the sliding support base 62, and is formed in a circular cross section that is rotatably supported by the arc surface 65a. It is supported rotatably with respect to the casing body 14. The support opening 32 is formed with an opening 32a which is partially cut away.
[0012]
Further, a toilet seat-side storage chamber 33 is formed so as to be continuous with the support opening 32 of the toilet seat 30. The viscous resistance mechanism 100 is stored in the toilet seat-side storage chamber 33. The viscous resistance mechanism 100 includes a support base 101 having a fitting recess 101a that fits into the fixed protrusion 70. The fitting recess 101a is formed in an elongated groove shape having an opening 101b at one end. The opening 101b is formed at a position corresponding to the central portion of the opening 32a, and the fitting recess 101a is configured such that the fixed protrusion 70 is removably inserted through the opening 101b.
[0013]
The viscous resistance mechanism 100 includes a viscous outer cylinder 103 rotatably supported by the support base 101, and a viscous outer cylinder 103 formed between the support base 101 and the viscous outer cylinder 103 and partitioned by a one-way valve 106. It includes a resistance chamber 107, a viscous body 108 filled in the viscous resistance chamber 107, and a connecting body 109 for engaging the viscous outer cylinder 103 with the inner wall of the toilet seat-side storage chamber 33 of the toilet seat 30. The connecting body 109 has a snap-fit configuration, and the viscous resistance mechanism 100 is formed by inserting a flathead screwdriver or the like from the through hole 34 provided in the toilet seat side storage chamber 33 to elastically deform the connecting body 109. It can be pulled out from the toilet seat side storage room 33.
[0014]
As shown in the cross-sectional view of FIG. 5, the viscous outer cylinder 103 is coupled to the toilet seat 30 by a key coupling portion 104 protruding from the viscous outer cylinder 103 so as to rotate integrally with the toilet seat 30. When the toilet seat 30 is opened and closed by the configuration of the viscous resistance mechanism 100, the viscous outer cylinder 103 rotates with respect to the support base 101, and the viscous resistance force of the viscous body 108 causes the toilet seat 30 to rotate gently. .
[0015]
A bottomed hole 41 of a toilet lid 40 is rotatably supported by the viscous outer cylinder 103 of the viscous resistance mechanism 100. The toilet lid 40 is supported and thereby opened and closed by the viscous outer cylinder. Since the bottom 103 and the bottomed hole 41 are not connected, the toilet lid 40 rotates without receiving a viscous resistance force.
[0016]
Although not shown, a viscous resistance mechanism is also provided in the other toilet seat support mechanism of the toilet seat 30 and the toilet lid 40 in a configuration similar to that of FIG. 3. The key connecting portion 104 protruding from the viscous outer cylinder 103 is configured to be coupled to the toilet lid 40. Therefore, the rotation of the toilet seat 30 does not rotate the viscous outer cylinder 103, but the rotation of the toilet lid 40. Is different in that the viscous outer cylinder 103 rotates and the viscous resistance of the viscous body acts on the toilet lid 40.
[0017]
Next, the opening / closing operation of the toilet seat 30 and the toilet lid 40 via the toilet seat lid support mechanism 20 will be described with reference to FIGS. 5 shows a state where the toilet seat 30 is closed and the toilet lid 40 is opened, and FIG. 6 shows a state where the toilet seat 30 and the toilet lid 40 are opened to the vertical position.
[0018]
In the state shown in FIG. 5, the support opening 32 of the toilet seat 30 is supported by the arcuate surface 65 a of the sliding support base 62, and the fixed protrusion 70 is fitted in the fitting recess 101 a. The support opening 32 slides on the arcuate surface 65a of the sliding support base 62 according to the operation, and at the same time, the viscous outer cylinder 103 of the viscous resistance mechanism 100 integrated with the toilet seat 30 applies the viscous resistance force to the support base 101. It turns while having.
[0019]
Therefore, the toilet seat 30 is firmly supported by the fixing protrusion 70 and the fitting recess 101 a of the support base 101, and is firmly supported in a contact state by the arc surface 65 a of the sliding support base 62 and the support opening 32. By the rotation of the viscous outer cylinder 103, a smooth opening / closing operation is performed with viscous resistance. In other words, the toilet seat 30 can be smoothly opened and closed by the two supporting structures of the toilet seat toilet lid support mechanism 20 without rattling against the sliding support base 62 of the casing body 14.
[0020]
Further, the toilet seat toilet lid support mechanism 20 is provided with a lock mechanism 120 for locking and releasing the toilet seat 30 and the toilet lid 40 so as not to come off from the casing body 14. The lock mechanism 120 is connected to the lock engagement member 122 inserted into the insertion hole 121 formed in the slide support base 62, a holder member 123 that holds the lock engagement member 122, and is provided continuously with the holder member 123. A lock release button 124 and a spring 126 that is supported at one end by the casing body 14 and abuts against and biases the holder member 123 at the other end. The distal end of the lock engagement member 122 protrudes into an engagement recess 127 formed in the support base 101 of the viscous resistance mechanism 100 so as to be able to advance and retreat.
[0021]
With the configuration of the lock mechanism 120, when the lock release button 124 is pushed in the direction of the arrow, the holder member 123 moves integrally with the lock release button 124 against the urging force of the spring 126. As a result, the lock engagement member 122 fixed to the holder member 123 retreats and comes out of the engagement recess 127 of the support base 101. On the other hand, when the lock release button 124 is released, the distal end portion 122 a of the lock engagement member 122 is pushed into the engagement recess 127 by the urging force of the spring 126, thereby preventing the toilet seat 30 from falling out of the casing body 14. .
[0022]
To remove the toilet seat 30 and the toilet lid 40 from the casing body 14 via the toilet seat toilet lid support mechanism 20, as shown in FIG. push. That is, at the vertical position of the toilet seat 30, the opening 32 a is in a state of being removed because it is aligned with the position of the vertical surface 65 b of the sliding support base 62. Through the opening 101b. Therefore, at the vertical position of the toilet seat 30 and the toilet lid 40, the toilet seat 30 can be released from supporting the main body support portion 60. Further, when the lock release button 124 is pressed, the lock engagement member 122 comes out of the fitting recess 101a against the spring force via the holder member 123.
[0023]
In this state, if the toilet seat 30 and the toilet lid 40 are pulled up, the toilet seat 30 and the toilet lid 40 can be easily removed from the casing body 14. Then, the toilet seat 30 and the toilet lid 40 removed from the casing main body 14 can easily clean them all over. On the other hand, in order to attach the toilet seat 30 and the toilet lid 40 to the casing main body 14, the toilet seat 30 and the toilet lid 40 are set in the same vertical state as the state where the toilet seat 30 and the toilet lid 40 are removed, and Is aligned with the sliding support base 62 and then lowered. Thereby, after being pushed by the end of the support base 101 and the lock engagement member 122 being pushed in against the urging force of the spring 126, the lock engagement member 122 is supported in the original state of FIG. Therefore, the operation of the lock mechanism 120 is not required to attach the toilet seat 30 and the toilet lid 40 to the casing body 14.
[0024]
According to the above embodiment, the toilet seat 30 and the toilet lid 40 are rotatably supported by the casing main body 14 via the toilet seat and toilet lid support mechanism 20, and the lock is maintained even when the toilet seat 30 and the toilet lid 40 are opened in the vertical direction. Unless the lock release button 124 of the mechanism 120 is operated, the toilet seat 30 and the toilet lid 40 cannot be removed from the casing body 14, so that the toilet seat 30 and the toilet lid 40 do not come off accidentally. Moreover, the toilet seat 30 and the toilet lid 40 can be easily removed by an easy operation of pressing the lock release button 124.
[0025]
Moreover, since the opening 528 and the like are not elastically deformed in attaching and detaching the toilet seat 30 and the toilet lid 40 as in the related art, the durability is excellent.
