Description

  The present invention relates to a warm water cleaning toilet seat device, and more particularly to a warm water cleaning toilet seat device mounted on a rear portion of a toilet rim surface.

  As is well known, a warm water cleaning toilet seat device (also called a human body local cleaning device) mounted or installed at the rear of the toilet rim surface is basically a toilet seat on which a user is seated and a rear portion of the toilet seat. A cleaning nozzle device for cleaning the user, a hot air drying device for performing hot air drying, and the like, and a box unit in which these control devices are accommodated. A toilet lid is provided on the toilet seat so as to cover the toilet seat, and a rear end portion of the toilet seat and the toilet lid is rotatably attached to the box portion. In such a configuration, a relatively large gap is required between the toilet seat and the box portion and between the toilet lid and the box portion because of its structure, so that dirt and dust are likely to adhere to the gap. Further, when wiping off dirt with a rag or the like, there was an unfavorable point such as leaving unwiped. Furthermore, in terms of design, it is divided into a toilet seat and a box part, and it is also true that the degree of freedom in modeling is limited.

In view of the above circumstances, from the above, Patent Document 1 discloses that the toilet seat and the box portion are integrated, and the bottom plate of the box portion is turned to the rear end of the mounting member that is directly fixed to the rim surface of the toilet bowl. Disclosed is a warm water washing toilet seat device that is movably supported. In the warm water cleaning toilet seat device having such a configuration, the lower side of the bottom plate of the box portion and the toilet bowl are formed by rotating the box portion rearward and lifting the toilet lid and toilet seat supported by the box portion rearward. The rim surface can be exposed. Thus, it is possible to easily clean the lower surface of the bottom plate of the box portion and the toilet rim surface without removing the entire toilet seat device from the toilet bowl, which is excellent in practical use.
Japanese Utility Model Publication No. 5-4995

  Certainly, as shown in Patent Document 1, the toilet seat and the box portion are integrated with each other, and the bottom plate of the box portion is rotatably supported at the rear end of the mounting member fixed directly to the rim surface of the toilet bowl. If such a configuration is adopted, it is possible to easily clean the lower surface of the bottom plate of the box part and the toilet rim surface without removing the entire toilet seat device from the toilet bowl, but it is delicate in the peripheral structure of the toilet bowl. Influence. That is, in the configuration disclosed in Patent Document 1, the bottom plate of the box portion is rotatably supported on the rear end of the mounting member fixed directly to the rim surface of the toilet bowl, so that the box portion is placed on the rim surface of the toilet seat. The toilet seat integrated with the box is held in the open position by turning the box so that the rear end surface of the box is placed on the rim surface. can do. The box part is pivotally supported by the rear end of the toilet lid that covers the toilet seat. The pivot position pivots to the rear end of the mounting member fixed directly to the rim surface of the toilet bowl. Since the position is higher and higher than the position where it can be hindered, when the box part is turned 90 degrees and the rear end face is placed on the rim surface, the toilet lid is turned backward to move to the low tank. In order not to collide, it was necessary to keep the toilet lid away from the toilet seat by hand, which was difficult to operate.

  Therefore, the present invention is such that when the rear end surface of the box portion with the toilet seat integrally held in the front portion is pivotally attached to the toilet rim surface and the rear end portion of the toilet lid is pivotally attached to the box portion, An object of the present invention is to provide a warm water washing toilet seat device in which the toilet lid does not collide with the low tank when rotating backward.

In order to solve the above technical problem, the technical means taken in the invention of claim 1 is:
“A toilet seat unit integrally provided with a seat surface portion and a box portion on the front side and the rear side, respectively, and a cleaning mechanism and other mechanisms housed inside the box portion, the box portion being a rear portion of the toilet rim surface When the toilet seat unit is pivotally supported at a predetermined height position of the bracket fixed to the closed position, the seat surface portion is placed on the toilet rim surface, and the seat surface portion is relative to the toilet rim surface. Further, the rear end of the toilet lid is pivotally shifted between an open position that forms a right angle or an obtuse angle, and the rear end of the toilet lid that covers the seat surface is pivotally supported by the box portion. Is a warm water washing toilet seat device supported by a stopper member standing from the bracket in the open position "
It is to have constituted.

  According to the first aspect of the present invention, when the toilet seat unit is pivoted to the open position, the rear end surface of the box portion is supported by the stopper member provided upright from the bracket, and thus collides with the low tank. There is nothing, and there is a great effect in practical use.

  The best mode for carrying out the present invention will be described with reference to FIGS.

  The warm water washing toilet seat device 10 includes a toilet seat unit 20. Thus, the toilet seat unit 20 is formed by integrally molding a seat surface portion 22 located on the front side and a box portion 24 located on the rear side. As a raw material of the toilet seat unit 20, for example, resin or metal can be employed.

  Inside the box part 24 is housed a washing mechanism 30 for washing a specific part of a user who sits on the seat part 22 (a male / female buttocks or anal part and a female local part) with warm water.

  The toilet seat unit 20 is pivotally supported by a bracket 70 detachably fixed to the rear portion of the rim surface 12a of the toilet 12. Therefore, the rotation range of the toilet seat unit 20 is such that the seat surface portion 22 is placed on the toilet rim surface 12a via the rubber feet 22a and the rear end surface of the box portion 24 is between the toilet rim surface 12a. In addition, a predetermined gap G is defined, and the seat surface portion 22 is restricted to an open position at a right angle or an obtuse angle with the toilet rim surface 12a. And when the toilet seat unit 20 is turned to the open position, the gap G defined between the rear end surface of the box portion 24 and the toilet rim surface 12a is set to 20 mm or more, in particular. Cleaning on the rim surface 12a of the toilet 12 can be easily performed.

  On the rim surface 12 a of the toilet 12, a low tank 50 is further installed immediately after the box portion 24 of the toilet seat unit 20. Further, a toilet lid 60 capable of covering the seat surface portion 22 is pivotally supported on the box portion 24 of the toilet seat unit 20. Thus, the pivot point (rotation center) of the toilet lid 60 is coaxial with the rotation center of the toilet seat unit 20. With this coaxial setting, when the toilet seat unit 20 is rotated and moved from the closed position to the open position while the toilet seat unit 20 is held by hand, the toilet lid 60 does not rotate and move away from the toilet seat unit 20. When only the toilet lid 60 is moved downward in the closing direction, or when only the toilet seat unit 20 is gripped and the toilet seat unit 20 and the toilet lid 60 are rotated together in the opening direction, Even when only the toilet seat unit 20 is gripped, the toilet lid 60 does not change to the open position first.

  The bracket 70 is detachably fixed at a position near the hole 14 at the rear of the rim surface 12a of the toilet 12. That is, the bracket 70 includes a base plate 72, a pair of support bodies 74 and 74 that are erected integrally from the left and right sides of the base plate 72 at a predetermined interval in the toilet width direction, and an upward direction from the rear end of the base plate 72. And a pair of stopper members 76, 76 projecting integrally therewith. The support members 74 corresponding to the stopper members 76 are positioned on the same straight line in the toilet front-rear direction. A slot 74a having an upper opening is formed in the support 74, and an arm 78 is detachably fitted into the slot 74a. Both arms 78 and 78 have holes 78a and 78a that are coaxial in the toilet width direction. Further, a pair of screw rods 79 and 79 are formed on the lower surface of the base plate 72, and these screw rods 79 and 79 are screwed and fixed to a pair of holes in the rear part of the rim surface 12 a of the toilet 12. Thereby, the bracket 70 is detachably fixed at a position near the hole 14 on the rear side of the rim surface 12 a of the toilet 12.

  On the lower surface side of the box portion 24, a pair of slot portions 24a and 24a are formed which are located at a predetermined interval in the toilet width direction and are immersed therein. Thus, when the box portion 24 integral with the seat surface portion 22 is placed on the rear portion of the rim surface 12a of the toilet bowl 12 so as to overlap the bracket 70, the arms 78 and 78 of the bracket 70 are moved to the box portion 24. Are accommodated in the slots 24a and 24a.

  Under this state, inside the box portion 24, the hinge pin 80 passes through the left surface of the portion 24b forming the outline of the one slot portion 24a, the hole 78a of the one arm 78, and the right surface of the portion 24b. The head of the hinge pin 80 engages with the left surface of the portion 24b, and the tip of the hinge pin 80 engages with the right surface of the portion 24b by caulking. As a result, the hinge pin 80 is prevented from coming out of the portion 24b forming the outline of the one slot portion 24a. In addition, in the box portion 24, the shaft portion 82a of the damper 82 is loosely fitted to the hole 78a of the other arm 78 after loosely fitting the left surface of the portion 24b forming the outline of the other slot portion 24a. . Thus, the box portion 24 is pivotally supported with respect to the arms 78 and 78 of the bracket 70, and the box portion 24 moves quickly without being acted upon by the damper 82 when it is pivoted in the opening direction. When the rotational movement is made in the closing direction, a gentle movement is performed by the action of the damper 82, and the seat surface portion 22 prevents a collision with the toilet 12 rim surface 12a. The damper 82 is clamped and fixed on a base 24c formed adjacent to the left surface of the portion 24b that forms the outline of the other slot portion 24a. Of course, the axis of the hinge pin 80 and the axis of the shaft portion 82a of the damper 82 are concentric.

  A toilet lid 60 capable of covering the seat surface portion 22 is pivotally supported on the box portion 24 of the toilet seat unit 20. That is, a boss portion 60a is formed on the inner surface of one side of the toilet lid 60, and a shaft portion 86a of a damper 86 protruding from one wall surface of the box portion 24 is tightly fitted and fixed in the boss portion 60a. ing. Further, a land portion 60 b is formed on the inner surface of the other side of the toilet lid 60, and this land portion 60 b is rotatably inserted into a boss portion 24 p formed on the other wall surface of the box portion 24. . Thus, the toilet lid 60 is pivotally supported with respect to the box portion 24. When the toilet lid 60 is pivoted in the opening direction, the toilet lid 60 moves quickly without being affected by the damper 86, and in the closing direction. When rotating and changing, the damper 86 performs a gentle motion to prevent the toilet lid 60 from colliding with the seat surface portion 22. As a matter of course, the shaft portion 86a of the damper 86 and the shaft core of the land portion 60b are concentric.

  Thus, the shaft portion 86a of the damper 86 and the shaft core of the hinge pin 80 are concentric, and the shaft portion 82a of the damper 82 and the shaft core of the land portion 60b are concentric. The pivot point (rotation center) of the toilet lid 60 is coaxial with the rotation center of the toilet seat unit 20. With this coaxial setting, when the toilet seat unit 20 is rotated and moved from the closed position to the open position while the toilet seat unit 20 is held by hand, the toilet lid 60 does not rotate and move away from the toilet seat unit 20. When only the toilet lid 60 is moved downward in the closing direction, or when only the toilet seat unit 20 is gripped and the toilet seat unit 20 and the toilet lid 60 are rotated together in the opening direction, Even when only the toilet seat unit 20 is gripped, the toilet lid 60 does not change to the open position first.

  As described above, the pair of stopper members 76 and 76 are erected and formed from the two corner portions of the rear end portion of the base plate 72 of the bracket 70. In the vicinity of the distal end portion of each stopper member 76, a groove 76a having a trapezoidal cross section that opens to the low tank 50 side is formed. The opening of the groove 76a expands in the direction of the low tank 50. Thus, as clearly shown in FIG. 15, the inner surface of the rear end of the toilet lid 60 has a pair of protrusions 60p and 60p (only one shown) and a predetermined distance in the toilet width direction. A recess 60q adjacent to the front of the protrusion 60p is formed. In particular, as clearly shown in FIG. 17, the protrusion 60p of the toilet lid 60 fits into the groove 76a of the stopper member 76, and the open position thereof. Is retained.

  When the toilet seat unit 20 is in the closed position (use position), the stopper member 76 is engraved on the back surface of the box portion 24 (that is, on the low tank 50 side), as clearly shown particularly in FIGS. Although it is in a state loosely fitted in the groove 24g, when the toilet seat unit 20 is in the open position (non-use position), as shown in FIG. There is no overlapping relationship with the toilet seat unit 20.

  As clearly shown in FIGS. 6 to 8, the lower surface 24 p of the box portion 24, which is the rear side of the seat surface portion 22 of the toilet seat unit 20, has a gentle arc shape. Accordingly, when the cleaning mechanism 30 is used, the cleaning water that has been sprayed onto the nozzles 32 or adhered to the lower surface 24r of the box portion 24 to form water droplets is converted into the box portion when the toilet seat unit 20 is rotated to the open position. By allowing the lower surface 24p of 24 to be positioned on the hole 14 of the toilet 12, water drops fall into the toilet 12. Thus, the problem that water stays or adheres between the lower surface 24p of the box portion 24 and the rim surface 12a of the toilet 12 is prevented in advance.

  The cleaning mechanism 30 will be described with reference to FIGS. 13, 19, and 20. The cleaning mechanism 30 installed in the box unit 24 includes an anal cleaning nozzle unit 31 for cleaning the anus of the user sitting on the seat surface unit 22 and a bidet cleaning for cleaning the local part when the user is a woman. The unit 32 is provided. The anus cleaning nozzle portion 31 (bidet cleaning portion 32) includes a base tube portion 311 (321) fixed to the lower surface 24p of the box portion 24, and a nozzle body 312 that is housed in the base tube portion 311 (321) so as to freely advance and retract. (322). Thus, when water from a water supply source (not shown) is pumped into the hot water tank 35 via the water supply port 33 and the electromagnetic stool 34, the temperature is raised and maintained at a predetermined temperature by a heater (not shown) in the hot water tank 35. The heated hot water is pushed out and reaches the base tube portion 311 (321) of the anal cleaning nozzle portion 31 (the bidet cleaning portion 32) through the first position (the second position) distribution valve (not shown). Then, the nozzle body 312 (322) is pushed out from the base tube portion 311 (321). The extruded nozzle body 312 (322) passes through the opening 24z and stops at a predetermined position inside the toilet 12, and hot water is injected into the anus (female local area) from an injection hole (not shown) formed at the tip. And cleaning is performed. After this cleaning, the nozzle body 312 (322) returns to the original position along with the stop of the hot water pumping to the base tube portion 311 (321), and then the hot air jetted from the hot air nozzle Then, it passes through the opening 24y and is sprayed on the cleaned part to be dried. The electronic components of the cleaning mechanism 30 are controlled by a control device 36 based on a CPU (not shown).

  Thus, as clearly shown in FIG. 19, a shutter 90 is provided in the opening 24 z that is provided below the box portion 24 and is opened / exposed to the inside (hole 14) of the toilet 12. When the toilet seat unit 20 is in the closed position (open position), the shutter 90 opens the opening 24z as indicated by a solid line in FIG. 19 (indicated by a virtual line in FIG. 19 and a solid line in FIG. 20). (Block). When the toilet seat unit 20 is in the open position with the shutter 90, the opening 24z is mainly closed as shown by the phantom line in FIG. 19 and the solid line in FIG. This is to prevent damage to the components of the cleaning mechanism 30 due to penetration of water or other liquid that has passed through the box portion 24. That is, as shown in FIG. 20, when the toilet seat unit 20 is in the open position, the shutter 90 that closes the opening 24 z of the box portion 24 faces a man standing in front of the toilet 12. Thus, when a man urinates toward the toilet 12, the urine released vigorously reaches the vicinity of the opening 24z of the box portion 24 depending on the conditions that may occur. Since it is occluded, the urine does not enter the box portion 24 and the components of the cleaning mechanism 30 are not damaged. The same water-proofing effect also works for water used for cleaning.

  The structure of the shutter 90 described above will be specifically described with particular reference to FIG. A pair of supports 24s and 24s (only one is shown) are provided in the box portion 24 at a position close to the opening 24z at a predetermined interval in the toilet width direction.

A pin 91 is rotatably supported on each support 24s, and the pin 91 is fixed to a rear end portion (left side in FIG. 19) of the arm 92. Thus, the arm 92 passes through the opening 24z and reaches the inside of the toilet 12, which is the outside of the box portion 24. Here, the arm 92 is integrated with the shutter 90. As a result, the shutter 90 is pivotally attached to the box portion 24 via the pin 91 so that the rear end portion of the shutter 90 can be rotationally displaced. On the front end side of the shutter 90, a groove portion 90a extending in the toilet seat width direction (perpendicular to the paper surface of FIG. 19) is defined. The groove portion 90 includes a substance having a large weight per unit volume (for example, Rubber) is filled as the weight 93, and always urges the shutter 90 clockwise. Accordingly, in the state shown in FIG. 19 (that is, when the toilet seat unit 20 is in the closed position or the use position), the shutter 90 always opens the opening 24z, and the nozzle body 312 (322) enters the toilet 12 inside. It is possible to move forward.

  When the box portion 24 is turned upright, the toilet seat unit 20 is shifted to the open position (non-use position) as shown in FIG. In the course of this rotation, the action of the weight 93 causes the shutter 90 to rotate in the direction approaching the box portion 24 around the pin 91, so that the distal end portion 90x of the shutter 90 is above the inner edge portion 24q of the opening 24z. When the shutter 90 is engaged, the shutter 90 completely closes the opening 24z. The shutter 90 completely closes the opening 24z, and as shown in FIG. 20, the transition to the open position (non-use position) of the toilet seat unit 20 is established and maintained thereafter. Note that the shutter 90 has a bent shape that inclines toward the inside of the toilet 12 when the opening 24z is closed, so that, for example, urine radiated to the shutter 90 follows this inclination. Immediately transferred to the toilet 12.
