JP 2010-7451 A

  In recent years, in the toilet device, it is required to reduce the forward dimension of the toilet. When such a toilet device is constituted by a toilet device in which the toilet flushing tank is fixed to the toilet bowl, it is necessary to make the toilet flushing tank thin in order to reduce the forward dimension of the toilet bowl.

  However, when the toilet flushing tank is made thinner, the gap between the tank cover, which is the exterior body of the toilet flushing tank, and the toilet flushing tank arranged inside the tank cover is reduced in order to secure the tank volume. For this reason, if a load is applied to the tank cover, for example, when the user leans on the tank cover, the load may act on the toilet bowl cleaning tank. If the toilet flushing tank is made thinner, the bottom area becomes smaller, so the toilet flushing tank itself cannot receive the load, and the load acts on the tank body arranged in the toilet flushing tank. There is a concern that stress will be applied to the pipe connection part etc. that will lead to breakage and water leakage. Therefore, even if a load acts on the toilet bowl cleaning tank, it is required to avoid that the load acts directly on the tank body in the toilet bowl washing tank.

  The technique described in Patent Document 1 avoids deformation of the fixed plate by providing a flexible portion that is elastically deformed in the fixed plate and elastically deforming the flexible portion when a load is applied to the toilet bowl washing tank. I am doing so. However, this technique only avoids the deformation of the fixed plate, and does not protect the tank body from the load acting on the toilet flushing tank.

  An object of the present invention is to provide a toilet device capable of avoiding a load from directly acting on a tank body in the toilet flushing tank even when a load acts on the toilet flushing tank.

A reinforcing stay (for example, a reinforcing stay 61 described later) extending over the base plate is provided, and the reinforcing stay is directly or against the base plate. It is indirectly connected.

  (2) In the toilet device according to (1), side support members (for example, described later) that rise from the base plate along the toilet cleaning tank to both end surfaces (for example, an end surface 43a described later) in the width direction of the base plate. Preferably, side frame members 62) are provided, and both ends of the reinforcing stay are connected to the side support members, respectively.

  (3) In the toilet device according to (2), the side frame member is attached by engaging with a convex portion (for example, a convex portion 43c described later) or a concave portion provided on each of the both end surfaces of the base plate. It is preferable.

  (4) In the toilet device according to (2) or (3), the side frame member has a front plate portion (for example, a front plate portion 621a described later) disposed on the front side of the toilet bowl washing tank. The front plate portion has a boss portion (for example, a boss portion 624 described later), and the reinforcing stay has a groove portion (for example, a groove portion 611 described later) at both ends, and the groove portion is connected to the boss portion. It is preferable that it is screwed to the front plate part in a state of being engaged with the part.

  (5) In the toilet device according to any one of (1) to (4), the reinforcing stay is preferably curved in the width direction toward the front.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the toilet device 1 shown in this embodiment is a floor-standing toilet device in which the toilet 2 is installed on the floor surface f1. The toilet device 1 includes a toilet 2 and a toilet cleaning device 3 disposed behind the toilet 2. In the following description, the front-rear direction when viewed from the user seated on the toilet 2 is defined as the front-rear direction. Further, the left-right direction when viewed from the user seated on the toilet bowl 2 is defined as the width direction. Further, the vertical direction along the vertical direction with respect to the floor surface f1 is defined as the vertical direction.

  The toilet bowl 2 is installed on the floor surface f1 close to the standing wall surface f2. The toilet bowl 2 includes a toilet seat 22 and a toilet lid 23 that are rotatably attached to an upper portion of the toilet bowl body 21, and a toilet seat device function unit 24 that is disposed behind the toilet seat 22 and the toilet lid 23. Yes. Side covers 211 are detachably attached to both side surfaces of the rear portion of the toilet body 21 by hook-and-loop fasteners or the like, respectively, and shield the rear portion of the toilet body 21.

  The toilet bowl cleaning device 3 is arranged behind the toilet bowl body 21. The toilet bowl cleaning device 3 includes a toilet bowl cleaning tank 4 and a tank cover 5 that is an exterior body of the toilet bowl cleaning tank 4.

  The tank cover 5 shown in the present embodiment includes a front cover 51 that covers the front of the toilet bowl cleaning tank 4, a rear cover 52 that covers the side and rear of the toilet bowl cleaning tank 4, and an upper cover 53 that covers the top of the toilet bowl cleaning tank 4. And having. The front cover 51 and the upper cover 53 are detachably attached to the rear cover 52. Thereby, the whole toilet bowl washing tank 4 is shielded by the tank cover 5, the appearance is good, and the design is improved.

  The rear side of the toilet bowl 2 below the toilet bowl cleaning tank 4 is covered with a pair of left and right lower covers 54. Thereby, while piping parts (not shown) etc. which are arrange | positioned at the back side of the toilet bowl 2 are blindfolded, the back side of the toilet bowl 2 becomes a thin box shape extended downward from the toilet bowl washing | cleaning apparatus 3, and is designed. A sense of unity is created and design is further improved.

  As shown in FIG. 3, the toilet bowl cleaning tank 4 includes a tank body 41, an inner lid 42, a base plate 43, a dewproof material 44, and a reinforcing frame 6 inside the tank cover 5. In FIG. 3, only the toilet body 21 of the toilet bowl 2 is indicated by a broken line, and the toilet seat 22, the toilet lid 23, and the functional unit 24 are not illustrated.

  The tank body 41 is made of a blow molded product. The upper surface opening 411 (see FIG. 2) of the blown tank body 41 is formed by cutting the upper part of the blow molded product in a substantially horizontal direction. For this reason, the blow molded product can be molded by releasing in the front-rear direction, and there is no need to provide a draft angle for releasing like the injection molded product in the vertical direction. As a result, the outer peripheral surface of the tank main body 41 becomes a straight surface along the vertical direction, and can constitute a side wall surface extending perpendicularly to the floor surface f1. For this reason, the tank body 41 is less likely to reduce the tank volume due to the draft, and even if the depth dimension is reduced to make it thinner, it is possible to ensure a larger tank volume than the injection molded product. By reducing the thickness of the tank body 41, the toilet device 1 including the toilet cleaning tank 4 having the tank body 41 can reduce the dimension in the front-rear direction (the above-mentioned dimension).

  Wash water is stored inside the tank main body 41, and as shown in FIG. 2, internal parts for toilet flushing are accommodated. Specifically, in the tank body 41, a ball tap 4a for supplying water, a float 4b for stopping the water of the ball tap 4a, an overflow for limiting the water level of washing water and supplying makeup water to the toilet body 21 A pipe 4c, a flapper valve 4d for opening and closing the drain port, a ball chain 4e for lifting the flapper valve 4d, a pulling arm 4f for pulling up the ball chain 4e, and the like are accommodated. A spindle 4h of a lever handle 4g attached to the outside of the tank cover 5 is connected to the pull arm 4f.

  The inner lid 42 is screwed to the tank main body 41 so as to cover the upper surface opening 411 (see FIG. 2) of the tank main body 41. Specifically, the inner lid 42 includes an inner lid body 421 and an inspection lid 422. The inner lid main body 421 is mounted along the periphery of the upper surface opening 411 and is screwed to the tank main body 41. On the other hand, the inspection lid 422 is not screwed to the tank body 41 and is detachably attached to the inner lid body 421. Therefore, the inner lid 42 can access the inside of the tank main body 41 without removing the screwed inner lid main body 421 by removing the inspection lid 422 from the inner lid main body 421.

  The base plate 43 is attached to the lower part of the tank body 41. The base plate 43 is formed of a resin harder than the tank body 41 and has a planar shape that is substantially equal to the bottom shape of the tank body 41. The base plate 43 supports the lower surface of the tank main body 41 and is fixed to the upper surface 21a of the rear portion of the toilet main body 21 by a pair of tightening bolts 431 (see FIG. 3) protruding from the bottom of the base plate 43. 41 has a function of fixing the toilet body 21 to the toilet main body 21.

  The attachment structure of the tank body 41 and the base plate 43 is shown in FIG. A circular lower surface opening 413 is formed on the bottom surface 412 of the tank body 41. A substantially cylindrical valve seat 46 is attached to the lower surface opening 413. The valve seat 46 is a component that constitutes a valve seat of a flapper valve 4d (not shown in FIG. 4) that is one of the internal components of the tank body 41, and has a flange portion 461 that is larger in diameter than the lower surface opening 413. have. The valve seat 46 is mounted from the inside of the tank main body 41 so that the packing 46 a is sandwiched between the flange portion 461 and the tank main body 41.

  The valve seat 46 integrally has a cylindrical portion 462 having an external thread on the outer peripheral surface on the lower side of the flange portion 461, and the cylindrical portion 462 protrudes downward from the lower surface opening 413. The valve seat 46 is attached to the tank body 41 by screwing a tightening nut 46b from the outside of the tank body 41 to a cylindrical portion 462 protruding from the lower surface opening 413.

  On the other hand, a circular opening 432 is provided in the central portion of the base plate 43, and a cylindrical portion 462 of the valve seat 46 that protrudes from the lower surface of the tank body 41 is inserted into the opening 432. The base plate 43 is sandwiched between the tightening nut 46c and the tank body 41 by screwing the tightening nut 46c into the cylindrical portion 462 projecting downward from the opening 432. Thereby, the base plate 43 is fixed to the lower part of the tank body 41.

  The base plate 43 fixed to the tank main body 41 is fixed by inserting a pair of tightening bolts 431 protruding from the lower surface into a tank mounting hole (not shown) provided in the upper surface 21a of the toilet main body 21. Thereby, the tank main body 41 is fixed to the toilet main body 21 via the base plate 43. The cylindrical portion 462 of the tank main body 41 fixed to the toilet main body 21 communicates with a flush water inlet (not shown) of the toilet main body 21 so that flush water in the tank main body 41 can be supplied to the toilet main body 21.

  The dewproof material 44 is formed in a shape along the outer peripheral surface of the tank main body 41 with a polystyrene foam resin or the like. The dew proof material 44 shown in this embodiment is divided into a front dew proof material 441 and a rear dew proof material 442, and is mounted so as to sandwich the tank body 41 from the front-rear direction. Thus, since the dewproof material 44 is divided into two in the front-rear direction, a draft angle when the dewproof material 44 is formed is also provided in the front-rear direction. Therefore, like the tank body 41, the dewproof material 44 can constitute a side wall surface that is straight in the vertical direction. As a result, even if the toilet bowl cleaning tank 4 is made thinner, there is no risk of reducing the tank volume of the toilet bowl cleaning tank 4 due to the draft angle of the dew-proof material as in the prior art. Moreover, combined with the fact that the tank body 41 shown in the present embodiment is not provided with a draft in the vertical direction, the toilet cleaning tank 4 is further reduced in thickness, and the dimensions of the toilet device 1 in the front-rear direction ( It is possible to further reduce the above-mentioned dimension).

  As shown in FIG. 3, the reinforcing frame 6 shown in the present embodiment is arranged on a reinforcing stay 61 made of a metal strip disposed on the front side of the toilet flushing tank 4 and on both sides of the toilet flushing tank 4. A metal side frame member 62.

  The reinforcing stay 61 is provided between the front cover 51 of the tank cover 5 and the tank body 41 not shown in FIG. 3, specifically, between the front cover 51 and the dewproof material 44 covering the tank body 41. It is arranged and extends over the width direction of the tank body 41. The front dewproof material 441 has a recess 44a extending in the width direction, and the reinforcing stay 61 is accommodated in the recess 44a. For this reason, the reinforcing stay 61 does not protrude excessively in front of the toilet cleaning tank 4, and the toilet cleaning tank 4 can be made thin without causing a reduction in the tank volume of the tank body 41.

  Both ends of the reinforcing stay 61 are connected to the side frame members 62, respectively. The side frame member 62 corresponds to the side support member of the present invention. The side surface frame member 62 includes a frame body 621 that is disposed along the side surface of the toilet bowl cleaning tank 4 (dewproofing material 44 that covers the tank body 41) and extends in the vertical direction, and a fixed plate portion 622.

  The frame main body 621 is formed in a U shape in plan view, and is formed to bend so as to bend around the front plate portion 621a bent around the front side of the tank main body 41 and the rear side of the tank main body 41. And a rear plate portion 621b. The front plate portion 621a and the rear plate portion 621b are provided with a pair of screw holes 623a and 623b arranged in the vertical direction. Further, the front plate portion 621a and the rear plate portion 621b are respectively provided with cylindrical boss portions 624 protruding outside the upper screw holes 623a and 623b of the pair of screw holes 623a and 623b.

  The fixed plate portion 622 is integrally provided at the lower end of the frame main body 621. The fixed plate portion 622 has a rectangular shape, and one screw hole 622a is provided in a central portion in the front-rear direction (a central portion in the width direction of the fixed plate portion 622). Accordingly, as shown in FIG. 5, the side frame member 62 has a symmetrical shape in the front-rear direction (the width direction of the side frame member 62), and can be attached to either the left or right side of the toilet flushing tank 4. ing.

  The side frame member 62 is fixed to the base plate 43 by fixing screws 62a that are fixed to the base plate 43 with the fixing plate portions 622 abutting against both end surfaces 43a in the width direction of the base plate 43, respectively. As a result, the side frame member 62 is provided so as to rise from the base plate 43 along the tank body 41, and is also divided into two parts by the front plate portion 621a and the rear plate portion 621b of the side frame member 62. 44 is sandwiched from the front-rear direction.

  Note that the front dewproof material 441 shown in the present embodiment has a recess 44b that accommodates the front plate 621a of the side frame member 62. For this reason, the side surface frame member 62 does not protrude excessively in front of the toilet bowl washing tank 4, and even if the reinforcing frame 6 is provided, the toilet bowl washing tank 4 is made thin without causing a reduction in the tank volume of the tank body 41. Can be

  The reinforcing stay 61 is fixed by a fixing screw 61a using a screw hole 623a on the upper side of the front plate portion 621a of each side frame member 62. Accordingly, the side frame members 62 are integrally connected by the reinforcing stay 61.

  The reinforcing frame 6 configured in this manner is such that when the front cover 51 is bent rearward by a user leaning on the front cover 51 of the tank cover 5, the reinforcing stay 61 is first moved forward. It functions so as to contact the cover 31 and receive the load and not directly apply the load to the tank body 41. A load acting on the reinforcement stay 61 is transmitted from both end portions of the reinforcement stay 61 to each side frame member 62. The side frame member 62 is fixed to a base plate 43 that is more robust than the tank body 41, and the base plate 43 is fixed to the toilet body 21, so that the load transmitted from the reinforcing stay 61 does not act directly on the tank body 41. It can be received and released to the toilet body 21. Further, since the front cover 51 comes into contact with the reinforcing stay 61, the bending of the front cover 51 itself is also suppressed, and damage to the front cover 51 can be avoided.

  The end surface 43 a of the base plate 43 is slightly recessed with a width corresponding to the width of the fixed plate portion 622 of the side surface frame member 62. As a result, as shown in FIGS. 5 and 6, a pair of wall portions 43 b are disposed on the front end side and the rear end side of the end surface 43 a of the base plate 43 so as to sandwich the fixing plate portion 622 from the front and rear along the vertical direction. Are formed respectively. In addition, on the inner side of the pair of wall portions 43b, a rectangular convex portion 43c integral with the wall portion 43b is projected. The convex portion 43c is disposed at a symmetrical position in the front-rear direction with the fixing screw 62a (screw hole 622a) interposed therebetween. These wall portions 43 b and convex portions 43 c are similarly provided on the end surface 43 a on the opposite side of the base plate 43.

  On the other hand, the fixing plate portion 622 of the side surface frame member 62 is formed with concave portions 622b that are recessed in a rectangular shape inward from both side edges of the fixing plate portion 622 at positions corresponding to the two convex portions 43c of the base plate 43. Has been. Thereby, the fixed plate portion 622 is fixed to the end surface 43a of the base plate 43 by the fixing screw 62a in a state where the convex portion 43c and the concave portion 622b are engaged with each other.

  Here, when the user leans on the front cover 51 and the front cover 51 bends backward and a load is applied to the reinforcing stay 61, the load F1 acts on the side frame member 62 as shown in FIG. To do. At this time, the side frame member 62 is acted on by a force to rotate clockwise in FIG. 6 around the fixing screw 62a. As a result, the convex portion 43c and the concave portion 622b are indicated by white arrows in FIG. Contact from the direction shown. That is, on the front side of the fixed plate portion 622 (left side in FIG. 6), the concave portion 622b comes into contact with the lower side of the convex portion 43c, and at the same time, on the rear side of the fixed plate portion 622 (right side in FIG. 6) The concave portion 622b comes into contact with the upper portion of the portion 43c.

  At this time, since the convex portion 43c and the concave portion 622b are in surface contact, the side surface frame member 62 can receive the load transmitted from the reinforcing stay 61 by the surface. As a result, the side frame member 62 can reliably receive the load transmitted from the reinforcement stay 61 when the reinforcement stay 61 receives a load, and the side frame member 62 is effectively tilted rearward. Can be suppressed.

  In addition, the load applied to the side surface frame member 62 substantially acts on the contact portion between the convex portion 43c and the concave portion 622b and hardly acts on the portion of the fixing screw 62a, so that the load applied to the fixing screw 62a can be reduced. Further, it is possible to suppress the occurrence of loosening of the fixing screw 62a.

  Note that when a force that pulls forward is applied to the toilet bowl washing tank 4, a load F <b> 2 is applied to the side frame member 62, contrary to the above. At this time, the side frame member 62 receives a force to rotate counterclockwise in FIG. 6 around the fixing screw 62a. As a result, the convex portion 43c and the concave portion 622b are painted black in FIG. Contact from the direction indicated by the arrow. That is, on the front side of the fixed plate portion 622 (left side in FIG. 6), the concave portion 622b abuts from the upper side of the convex portion 43c, and at the same time, on the rear side of the fixed plate portion 622 (right side in FIG. 6) The concave portion 622b comes into contact with the lower side of 43c. As a result, the side frame member 62 can receive the load transmitted from the reinforcing stay 61 on the surface due to the engagement between the convex portion 43c and the concave portion 622b as described above, and the side frame member 62 is excessively moved forward. Inclination can be effectively suppressed. For this reason, it is suppressed that the tank main body 41 tilts excessively forward.

  At both ends of the reinforcing stay 61, as shown in FIG. 7, each has a groove 611 that can be engaged with a boss 624 provided on the side frame member 62. When the boss portion 624 and the recessed groove portion 611 are engaged with each other, the screw hole (not shown) of the reinforcing stay 61 and the screw hole 623a on the upper side of the front plate portion 621a are arranged to coincide with each other. Has been. Thereby, when attaching the reinforcement stay 61 to the front plate part 621a of the side surface frame member 62, the reinforcement stay 61 can be positioned by engaging the groove 611 with the boss part 624. By this positioning, the screw hole (not shown) of the reinforcement stay 61 and the screw hole 623a on the upper side of the front plate portion 621a are aligned, so that the fixing screw 61a can be inserted easily, and the reinforcement stay 61 is attached. Workability is improved. Moreover, since the boss portion 624 can receive the load transmitted from the reinforcing stay 61 to the side frame member 62, it is possible to avoid loosening of the fixing screw 61a due to the load acting directly on the fixing screw 61a. it can.

  As shown in FIGS. 3 and 5, the reinforcing stay 61 is curved in the width direction of the toilet flushing tank 4 toward the front. That is, the reinforcing stay 61 is curved so that the center portion in the width direction protrudes most forward. Thereby, when a load is applied to the reinforcing stay 61 from the front side, the reinforcing stay 61 is elastically deformed so as to extend in the width direction, so that the load can be reliably released to the side frame member 62.

  As shown in FIG. 2, the front cover 51 is also curved in the width direction toward the front so that the center portion in the width direction protrudes most forward. In this case, it is preferable that the curvature of the reinforcing stay 61 is larger than the curvature of the front cover 51. As a result, as shown in FIG. 8, the distance between the front cover 51 and the reinforcing stay 61 is the smallest at the central portion and becomes larger toward both ends. Therefore, when the front cover 51 receives a load and bends backward (rightward in FIG. 8), the front cover 51 first comes into contact with the reinforcing stay 61 at the center in the width direction. Thereby, since the load can be distributed substantially evenly toward both ends of the reinforcing stay 61 and the load can be released to each side frame member 62 substantially uniformly, the toilet flushing tank 4 can be held more stably. Can do.

  As shown in FIGS. 2, 3, 5, and 7, the rear plate portion 621 b of each side frame member 62 is provided with an adjuster 7 that protrudes rearward. The adjuster 7 is screwed into the screw hole 623b on the lower side of the rear plate portion 621b so that the protrusion amount can be adjusted. As shown in FIG. 9, the adjuster 7 is provided to protrude rearward from the rear cover 52 by being attached to the side frame member 62 from an opening 521 formed in the rear cover 52. As shown in FIG. 2, the adjuster 7 abuts against the standing wall surface f <b> 2 to keep the distance between the standing wall surface f <b> 2 and the toilet bowl washing tank 4 constant, and prevents the toilet bowl washing tank 4 from being excessively tilted rearward. .

  In addition, the code | symbol 52a in FIG. 9 is a fixing screw for fixing the rear cover 52 to the upper screw hole 623b of the rear surface plate part 621b of the side surface frame member 62. The fixing screw 52 a is attached to a mounting hole 522 disposed above the opening 521 for the adjuster 7. As a result, the rear cover 52 is attached to the side frame member 62. Since the front cover 51 and the upper cover 53 are attached to the rear cover 52, the tank cover 5 shown in the present embodiment is indirectly fixed to the toilet body 21 via the side frame member 62 and the base plate 43.

  In the above embodiment, in the engagement structure between the side frame member 62 and the base plate 43, the two convex portions 43c and the concave portions 622b are provided. However, the convex portion 43c and the concave portion 622b may be provided one by one. Good. Further, the base plate 43 may be provided with a concave portion, and the fixed plate portion 622 may be provided with a convex portion. Further, the engagement structure between the side frame member 62 and the base plate 43 may be a fitting structure with a boss portion and a boss hole.

  The fixing plate portion 622 of the side surface frame member 62 is not limited to the one having the rectangular concave portion 22b that engages with the convex portion 43c. For example, in order to deal only with the load acting from the front cover 51, the lower side of the front (left side) convex portion 43 c and the upper side of the rear (right side) convex portion 43 c shown in FIG. The both side edges of the fixed plate portion 622 may be formed in a step shape (key shape) in the vertical direction.

  In the above embodiment, the reinforcement stay 61 is indirectly connected to the base plate 43 via the side frame member 62. For example, the reinforcement stay 61 corresponds to the side frame member 62. , The reinforcing stay may be directly connected to the base plate 43.

  Furthermore, both end surfaces 43a of the base plate 43 are not limited to flat surfaces. For example, the base plate 43 may have an elliptical shape in plan view. In this case, the side frame member 62 may be attached to the curved surfaces at both ends of the base plate 43.
