Definitions

  • aspects of the present invention generally relate to a toilet apparatus, and specifically relate to a toilet apparatus capable of using water to cleanse the "bottom" and the like of a user sitting on a western-style sit-down toilet.
  • the cause of this decline is that the enlargement of the casing causes the hinge position of the toilet seat to be higher than that of the initial local cleansing apparatuses.
  • this decline is because a rear portion of the seat face of the toilet seat has an ascending configuration inclined upward, and the rear of the buttocks of a person sitting on the toilet seat undesirably contacts the inclined portion.
  • the contact of the rear of the buttocks with a foreign object results in a ticklish sensation; and further, in the case of a heated toilet seat including a heater in the interior of the toilet seat, a cold sensation is experienced, causing a decline in the sitting comfort of the toilet seat.
  • aspects of the present invention were conceived based on the awareness of the relevant problems, and are directed to downsize a casing mounted on an upper portion of a toilet to improve the sitting comfort of a toilet seat while maintaining functions of a local cleansing apparatus.
  • a toilet apparatus comprising: a toilet including a bowl, a recess formed on an upper face to communicate with the bowl, and a communicating portion that links the bowl and the recess; a casing provided above the toilet; a toilet seat pivotally supported to open and close with respect to the casing; a cleansing nozzle, at least partially disposed on the recess, that passes through the communicating portion and extends into and retracts from the bowl; and a shutter, pivotally supported to rotationally move with respect to the casing, that opens the communicating portion when the cleansing nozzle extends and closes the communicating portion when the cleansing nozzle retracts.
  • FIG. 1 shows schematic perspective views illustrating a toilet apparatus according to an embodiment of the present invention.
  • FIG. 1A is a schematic perspective view illustrating a state in which a cleansing nozzle is stored in a casing; and FIG. 1B is a schematic perspective view illustrating a state in which the cleansing nozzle is extended out from the casing.
  • the toilet apparatus of this embodiment includes a western-style sit-down toilet (hereinbelow referred to as simply "toilet") 100 and a casing 200 provided on a rear upper portion thereof.
  • An interior of the casing 200 is provided with, for example, a local cleansing unit, which performs a cleansing of the "bottom” and the like of a user sitting on a not-illustrated toilet seat, and the like.
  • the toilet seat and a toilet lid, which are not illustrated, are pivotally supported to open and close with respect to the casing 200 by pivotal support portions 211 and 213, respectively, provided on the casing 200.
  • An upper portion of the casing 200 is provided with a seat contact sensor 215 that detects that the user is sitting on the toilet seat.
  • a seat contact sensor 215 detects that the user is sitting on the toilet seat
  • an operation of a not-illustrated switch by the user may cause the cleansing nozzle 241 to extend into a bowl 101 of the toilet 100 as illustrated in FIG. 1B .
  • the cleansing nozzle 241 extends by passing through an aperture portion of the casing 200. At this time, the cleansing nozzle 241 may extend into the bowl 101 by upwardly pushing a shutter 230, which opens and closes the aperture portion of the casing 200.
  • a tip portion of the cleansing nozzle 241 is provided with one or a plurality of water discharge ports 243.
  • the cleansing nozzle 241 can cleanse the "bottom” and the like of a user sitting on the toilet seat by squirting water from the water discharge port 243 provided on the tip portion thereof in the state of being extended into the bowl 101.
  • References to "water” in the description of the present application include not only cold water but also heated warm water.
  • the shutter 230 is pivotally supported to rotationally move with respect to the casing 200; and is urged in a direction to close the aperture portion of the casing 200 by an urging member such as a spring, etc. Therefore, the shutter 230 can open the aperture portion of the casing 200 by rotationally moving around an upper portion, as illustrated in FIG. 1B , by receiving a force from the extending cleansing nozzle 241. On the other hand, in the case where the cleansing nozzle 241 retracts, the shutter 230 no longer receives the force from the cleansing nozzle 241 and therefore can rotationally move due to the urging force to close the aperture portion of the casing 200.
  • the casing 200 includes an extended portion 217 provided to extend toward the front of the bowl 101. At least a portion of the extended portion 217 enters into the bowl 101 when viewed perpendicular to a bowl upper face (hereinbelow also referred to as simply "upper face") 105. Therefore, the shutter 230 is disposed below the extended portion 217. That is, the shutter 230 in the closed state is covered from above by the extended portion 217.
  • the interior of the casing 200 may be provided with, for example, a deodorizing unit (hereinbelow also referred to as “deodorizing apparatus”) that draws air from inside the bowl 101 of the toilet 100 and reduces offensive-odor components via a filter, catalyst, etc.; a warm air drying unit (hereinbelow, also referred to as “warm air drying apparatus”) that dries by blowing warm air toward the "bottom” and the like of the user sitting on the toilet seat; a room heating unit (hereinbelow also referred to as “room heating apparatus”) that heats the toilet room by blowing warm air into the toilet room; and the like.
  • a deodorizing unit hereinbelow also referred to as "deodorizing apparatus”
  • warm air drying unit hereinbelow, also referred to as “warm air drying apparatus”
  • room heating apparatus room heating apparatus
  • FIG. 2 is an enlarged schematic cross-sectional view of the shutter proximity of this embodiment.
  • FIG. 3 is a schematic perspective view illustrating the toilet of this embodiment.
  • FIG. 2 illustrates the state in which the cleansing nozzle is stored in the casing and corresponds to a cross-sectional view along A-A of FIG. 1A .
  • the casing 200 includes a case cover 210 and a case plate 220.
  • Devices such as a local cleansing unit are disposed on the case plate 220 and covered from above by the case cover 210.
  • the case plate 220 includes a recessed portion 223 formed in a configuration recessed downward.
  • the recessed portion 223 is provided on a portion of the case plate 220 and is inclined to become lower from the rear toward the front.
  • a front end portion of the recessed portion 223 is provided with an aperture portion 223b which allows the cleansing nozzle 241 to pass through. That is, the cleansing nozzle 241 extends or retracts by passing through the aperture portion 223b.
  • the toilet 100 includes a recess 103 formed in a configuration recessed downward from the bowl upper face 105 as illustrated in FIG. 3 .
  • a communicating portion 103b that communicates with the bowl 101 is provided on a front end of the recess 103; and similar to the recessed portion 223 provided on the case plate 220, the recess 103 is inclined to become lower from a rear end portion 103a thereof toward a front end portion (the communicating portion) 103b.
  • the case plate 220 is disposed on the bowl upper face 105 of the toilet 100 in a state in which the recessed portion 223 is stored in the recess 103 of the toilet 100. Therefore, the cleansing nozzle 241 extending and retracting by passing through the aperture portion 223b is equivalent to the cleansing nozzle 241 extending and retracting by passing through the communicating portion 103b.
  • the shutter 230 is mounted on the case plate 220 to open and close the aperture portion 223b of the recessed portion 223.
  • the shutter 230 is provided to cover the communicating portion 103b and the aperture portion 223b, and is pivotally supported to rotationally move with respect to the case plate 220. More specifically, the shutter 230 is pivotally supported to rotationally move with respect to the case plate 220 around a shaft 228 held by a bearing portion 227 of the case plate 220.
  • the shutter 230 includes a protruding wall 231 extending toward the communicating portion 103b and the aperture portion 223b in the closed state. I n other words, the shutter 230 includes the protruding wall 231 on a back face that faces the communicating portion 103b and the aperture portion 223b. The protruding wall 231 partially abuts the aperture portion 223b in the state in which the shutter 230 is closed. In other words, the protruding wall 231 partially abuts the aperture portion 223b; and thereby, the closed stopping position of the shutter 230 is determined.
  • the case cover 210 includes an extended portion 217 provided to extend toward the front of the bowl 101. At least a portion of the extended portion 217 enters into the bowl 101 as illustrated in FIG. 2 . Therefore, the shutter 230 is disposed below the extended portion 217. That is, the shutter 230 in the closed state is covered from above by the extended portion 217. I n other words, the shutter 230 is provided at a position retracted further than the front face 217a of the extended portion 217. Therefore, the extended portion 217 overhangs the shutter 230 in the closed state.
  • the bearing portion 227 of the case plate 220, the shaft 228 held by the bearing portion 227, and a pivotal support portion 237 (referring to FIG. 4 ) provided on the shutter 230 are disposed below the extended portion 217, and are covered from above by the extended portion 217.
  • the bearing portion 227, the shaft 228, and the pivotal support portion 237 are provided at a position retracted from the front face 217a of the extended portion 217. Therefore, the extended portion 217 overhangs the bearing portion 227, the shaft 228, and the pivotal support portion 237.
  • the bearing portion 227, the shaft 228, and the pivotal support portion 237 are provided at an upper portion of the aperture portion 223b as illustrated in FIG. 2 . That is, the shutter 230 is pivotally supported to rotationally move at the upper portion thereof. Therefore, the bearing portion 227, the shaft 228, and the pivotal support portion 237 are disposed directly below the extended portion 217. Accordingly, the bearing portion 227, the shaft 228, and the pivotal support portion 237 are less apt to be directly excreted upon than is the lower portion of the shutter 230.
  • the shutter 230 includes a vertical face 233 on a surface on the bowl 101 side, and an inclined face 235.
  • the vertical face 233 is provided on the upper portion of the shutter 230.
  • the inclined face 235 is provided on the lower portion of the shutter 230 and is inclined to retract from the upper portion toward the lower portion.
  • the urine does not run up the inclined face 235. Also, even in the case where urine splatters from the inner wall face of the bowl 101 and adheres to the vertical face 233 of the shutter 230, the urine quickly runs downward. Therefore, even in the case where urine splatters from the inner wall face of the bowl 101 and adheres on the shutter 230, there is almost no risk that the urine may run toward the bearing portion 227, the shaft 228, or the pivotal support portion 237.
  • the toilet apparatus according to this embodiment can inhibit the adhesion of urine to the shaft 228 which pivotally supports the shutter 230; and therefore, the occurrence of offensive odors and the appearance of urinary calculus can be inhibited. Therefore, the toilet apparatus according to this embodiment can inhibit discrepancies such as the inability to open and close the shutter 230 due to urinary calculus.
  • An elastic body 107 having elasticity is provided between the recessed portion 223 of the case plate 220 and the recess 103 of the toilet 100.
  • the elastic body 107 supports the recessed portion 223 at a proximity to the aperture portion 223b, while ensuring a fluidic seal between the recessed portion 223 of the case plate 220 and the recess 103 of the toilet 100. That is, the elastic body 107 prevents urine and the like from entering between the recessed portion 223 of the case plate 220 and the recess 103 of the toilet 100.
  • the elastic body 107 is disposed also on the upper face 105 of the toilet 100 along the front edge of the case plate 220; ensures a fluidic seal between the case plate 220 and the upper face 105 of the toilet 100; and prevents the entry of urine and the like.
  • bearing portion 227 is provided on the case plate 220 and the pivotal support portion 237 is provided on the shutter 230 in the specific examples illustrated, the present invention is not limited thereto; the pivotal support portion may be provided on the case plate; and the bearing portion may be provided on the shutter.
  • FIG. 4 shows schematic perspective views illustrating a mount structure between the shutter and the case plate.
  • FIG. 4A is a schematic perspective view illustrating a state prior to mounting the shutter on the case plate; and FIG.4B is a schematic perspective view illustrating a state after the shutter is mounted on the case plate.
  • the case plate 220 includes the bearing portion 227 above the aperture portion 223b as described above in regard to FIG. 2 .
  • the shaft 228 is then held by the bearing portion 227.
  • the shaft 228 is bent in a hook shape at one end portion and held by being latched on a jutting portion 226 of the case plate 220.
  • the urging member 229 is mounted on the shaft 228 to urge the shutter 230. Examples of the urging member 229 include, for example, a so-called "torsion coil spring" and the like.
  • the shutter 230 includes the pivotal support portion 237 on the upper portion of a surface on the side opposite to the bowl 101 , that is, on the backside of the vertical face 233.
  • the pivotal support portion 237 includes a shaft hole that receives the shaft 228 mounted on the case plate 220. Also, at least a portion of the pivotal support portion 237 is provided with a notched portion in which the shaft 228 can be forcibly inserted into the shaft hole. Therefore, from the state illustrated in FIG. 4A , that is, the state in which the shaft 228 is mounted in the bearing portion 227 of the case plate 220, the shaft 228 can be forcibly inserted into the pivotal support portion 237 of the shutter 230.
  • the pivotal support portion 237 supports the shaft 228 held by the bearing portion 227; and the shutter 230 is pivotally supported to rotationally move with respect to the case plate 220 around the shaft 228.
  • a protruding portion 239 provided on the shutter 230 abuts an arm portion 229a of the urging member 229. Then, the protruding portion 239 rotationally moves with an operation of the shutter 230 and receives a load from the arm portion 229a. That is, when the shutter 230 is opened, the protruding portion 239 rotationally moves against the load from the arm portion 229a. Therefore, the shutter 230 is urged in a direction to close by the urging member 229.
  • the shutter 230 cannot open by itself, and opens by receiving a force from the cleansing nozzle 241 that extends into the bowl 101. Restated, the shutter 230 is pushed by the cleansing nozzle 241 and thereby opens around the shaft 228. On the other hand, when the cleansing nozzle 241 retracts to be stored in the casing 200, the shutter 230 does not receive the force from the cleansing nozzle 241 and therefore closes due to the urging force from the urging member 229. That is, in the state in which the cleansing nozzle 241 is not extended, the shutter 230 is in the closed state as illustrated in FIG. 1A . Accordingly, the shutter 230 can prevent urine excreted by the user, splashing sealing water, or the like from entering the cleansing nozzle 241 side through the aperture portion 223b.
  • FIG. 5 is an enlarged schematic cross-sectional view of the shutter proximity of this embodiment.
  • FIG. 5 illustrates the state in which the cleansing nozzle is extended from the casing, corresponding to a cross-sectional view along B-B of FIG. 1B .
  • a nozzle unit 240 including the cleansing nozzle 241 includes a nozzle washing chamber 245 on one end portion.
  • the nozzle washing chamber 245 can wash the outer circumferential surface of the cleansing nozzle 241 by squirting water from a water discharge port provided on an interior thereof.
  • the nozzle washing chamber 245 also can inhibit wash water that washes the outer circumferential surface from scattering when the cleansing nozzle 241 extends and retracts.
  • the cleansing nozzle 241 extends by passing through the nozzle washing chamber 245. At this time, the cleansing nozzle 241 pushes the shutter 230 from the rear and extends into the bowl 101 as illustrated in FIG. 5 .
  • the cleansing nozzle 241 can squirt water from the water discharge port 243 and cleanse the "bottom” and the like of the user sitting on the toilet seat.
  • the cleansing water squirted from the water discharge port 243 may splatter from the "bottom” and may splatter from the inner wall face of the bowl 101. Therefore, liquid waste and solid waste may scatter toward the shutter 230; but the bearing portion 227, the shaft 228, and the pivotal support portion 237 are disposed directly below the extended portion 217; and therefore, the liquid waste and the solid waste do not readily fall on the bearing portion 227, the shaft 228, or the pivotal support portion 237.
  • the route from inside the bowl 101 toward the bearing portion 227, the shaft 228, or the pivotal support portion 237 becomes narrow; and therefore, the liquid waste and solid waste falls even less readily on the bearing portion 227, the shaft 228, or the pivotal support portion 237.
  • the toilet apparatus according to this embodiment can inhibit the adhesion of liquid waste and solid waste on the shaft 228 that pivotally supports the shutter 230; and therefore, the occurrence of offensive odors and the appearance of urinary calculus can be inhibited. Therefore, the toilet apparatus according to this embodiment can inhibit discrepancies such as the inability to open and close the shutter 230 due to urinary calculus or solid waste.
  • FIG. 6 is a schematic cross-sectional view of the toilet apparatus according to this embodiment from the side.
  • FIG. 6 corresponds to a cross-sectional view along A-A of FIG. 1A .
  • the shutter 230 in the closed state is disposed below the extended portion 217 and is covered from above by the extended portion 217. Therefore, it would be nearly impossible for a user standing in front of the toilet 100 to see the shutter 230 from the standing posture.
  • the toilet apparatus according to this embodiment has an attractive appearance and can improve the designability. Also, a male that urinates in a standing posture cannot see the shutter 230, and therefore would rarely think to intentionally sprinkle urine on the shutter 230. That is, if the shutter 230 is in the line of sight of the user during urination, the user may think to intentionally sprinkle urine on the shutter 230; but for the toilet apparatus according to this embodiment, such thoughts are unlikely. Therefore, there is a low risk that urine may be sprinkled intentionally on the shutter 230.
  • the bearing portion 227, the shaft 228, and the pivotal support portion 237 are disposed directly below the extended portion 217 as described above in regard to FIG. 2 . Therefore, in the case where urine is intentionally sprinkled toward the bearing portion 227, the shaft 228, or the pivotal support portion 237, it is necessary to urinate substantially along a double dot-dash line C illustrated in FIG. 6 . However, such an action is nearly impossible. Accordingly, the risk is low that urine may be intentionally sprinkled on the bearing portion 227, the shaft 228, and the pivotal support portion 237.
  • FIG. 7 is an enlarged schematic perspective view of the shutter proximity of this embodiment.
  • FIG. 8 is a schematic plan view of the shutter proximity of this embodiment from the front.
  • FIG. 9 is a schematic plan view of the shutter proximity of this embodiment from above.
  • FIG. 9 corresponds to a cross-sectional view along D-D of FIG. 8 .
  • the toilet 100 includes the stepped recess portion 103c connected to the bowl inner wall face 101a. Then, the shutter 230 is provided to be received by the stepped recess portion 103c. Therefore, as illustrated in FIG. 7 and FIG. 9 , the surface of the shutter 230 on the bowl 101 side is in substantially the same plane as the bowl inner wall face 101a. That is, the difference in levels between the surface of the shutter 230 on the bowl 101 side and the bowl inner wall face 101a is minimized. Accordingly, effects can be obtained such as easy cleaning of the bowl inner wall face 1 01 a and the surface of the shutter 230.
  • the shutter 230 is provided to be received by the stepped recess portion 103c; and therefore, a unified appearance is provided to the shutter 230 and the toilet 100 as illustrated in FIG. 7 and FIG. 8 . Therefore, the toilet apparatus according to this embodiment has an attractive appearance and can improve the designability.
  • FIG. 10 is an enlarged schematic cross-sectional view of the protruding wall of the shutter of this embodiment.
  • FIG. 10 corresponds to an enlarged view of a region E of FIG. 9 .
  • the shutter 230 includes the protruding wall 231 that extends toward the aperture portion 223b in the closed state.
  • An outer circumferential face 231 a of the protruding wall 231 is disposed a distance F from an outer circumferential face 223c of the recessed portion 223 of the case plate 220 toward the central portion side of the toilet apparatus.
  • interference between the shutter 230 and the toilet 100 can be inhibited. Therefore, discrepancies such as the inability to close the aperture portion 223b of the recessed portion 223 due to interference between the shutter 230 and the toilet 100 can be inhibited. Furthermore, occurrences of an unpleasant sound (impact sound) due to interference between the shutter 230 and the toilet 100 each time the shutter 230 opens and closes can be inhibited.
  • the elastic body 107 is provided between the recessed portion 223 of the case plate 220 and the recess 103 of the toilet 100. Therefore, even in the case where the outer circumferential face 231 a of the protruding wall 231 is disposed further on the central side of the toilet apparatus than is the outer circumferential face 223c of the recessed portion 223, the entry of urine between the recessed portion 223 of the case plate 220 and the recess 103 of the toilet 100 can be inhibited.
  • the shutter 230 is disposed below the extended portion 217 in the closed state and covered from above by the extended portion 217. I n other words, the shutter 230 is provided at a position retracted from the front face 217a of the extended portion 217. Also, the bearing portion 227 of the case plate 220, the shaft 228 held by the bearing portion 227, and the pivotal support portion 237 provided on the shutter 230 are disposed directly below the extended portion 217. Therefore, urine that is excreted by the user does not readily fall on the bearing portion 227, the shaft 228, and the pivotal support portion 237.
  • the toilet apparatus according to this embodiment can inhibit the adhesion of urine to the shaft 228 that pivotally supports the shutter 230; and therefore, the occurrence of offensive odors and the appearance of urinary calculus can be inhibited.
