Description

  Aspects of the invention generally relate to a wall-mounted toilet unit and a support member.

  There is a wall-mounted toilet unit that supports the toilet in a state where it is lifted from the floor and has an appearance in which the toilet is attached to a wall surface. The wall-mounted toilet unit includes a toilet, a support member that supports the toilet, and a tank that supplies cleaning water to the toilet. The support member and the tank are provided behind the toilet wall surface and are concealed by the wall surface.

  The tank is connected to the toilet bowl through a washing tube. At this time, connection between the tank and the toilet bowl may be difficult due to an installation error of the tank and the toilet bowl or a manufacturing error of the toilet bowl. For this reason, it has been proposed that the position of the tank in the vertical direction and the front-back direction can be adjusted (for example, Patent Document 1).

  The support member is fixed to a building foundation such as a floor slab in order to ensure strength. On the other hand, the toilet bowl is provided above the floor finish. Therefore, the height of the toilet bowl (height of the seating surface) from the floor finishing surface may change depending on the floor finishing thickness. For this reason, it has been proposed that the height of the toilet bowl can be adjusted in the support member (for example, Patent Document 2).

  Since a tank supplies washing water to a toilet using gravity, it is arranged above the toilet. For this reason, if the height of the toilet bowl is adjusted, there is a concern that the distance between the toilet bowl and the tank changes, which affects the cleaning performance.

  For example, when the distance between the toilet bowl and the tank is shorter than a specified value, the momentum through which the cleaning water flows becomes low, and there is a possibility that the cleaning performance is deteriorated. On the other hand, if the distance between the toilet bowl and the tank becomes longer than the specified value, the momentum of the wash water will increase and a part of the wash water may be scattered outside the toilet bowl. Sex occurs. For example, there is a risk that the washing water may be applied to the user.

  It is also possible to adjust the height of the toilet bowl and the height of the tank and adjust the height of the tank according to the height of the toilet bowl. However, in this method of separately adjusting the height of the toilet bowl and the height of the tank, workability is degraded. For this reason, it is desired that the wall-mounted toilet unit and the support member used therefor can ensure cleaning performance and improve workability even when the height of the toilet is adjustable.

FIG. 1 is a perspective view illustrating a wall-mounted toilet unit according to the embodiment.
FIG. 2 is a side view illustrating the wall-mounted toilet unit according to the embodiment.
As shown in FIGS. 1 and 2, the wall-mounted toilet unit 10 includes a toilet 12, a tank 14, a support member 16, and a cabinet 18. The wall-mounted toilet unit 10 installs the toilet 12 in a state of floating from the floor FS of the toilet space. The wall-mounted toilet unit 10 forms, for example, an appearance in which the toilet 12 is attached to the wall surface WS. Here, the floor surface FS is, for example, a floor surface of a portion that is a foundation of architecture, such as a floor slab.

  The toilet 12 has an upper surface 12a and a bowl portion 12b. The upper surface 12a is, for example, a plane that is substantially parallel to the floor surface FS. The upper surface 12a may be inclined with respect to the floor surface FS, or may have a plurality of surfaces with different heights from the floor surface FS. The bowl portion 12b has a concave shape that is recessed downward from the upper surface 12a.

  On the toilet 12, a toilet seat, a toilet lid, etc. (not shown) are provided. The user excretes urine, feces, and the like into the bowl portion 12b while sitting on the toilet bowl 12. The toilet 12 receives excrement such as urine and feces of the user in the bowl portion 12b. In other words, the toilet bowl 12 is a Western-style seated toilet.

  The bowl portion 12b is connected to a drain trap pipe not shown. The bowl portion 12b is connected to the drain pipe via a drain trap pipe, a drain socket, and the like, and allows waste or the like to flow through the drain pipe. The bowl portion 12b and the drain trap pipe are formed so that a predetermined amount of water can be stored in the bowl portion 12b when not in use.

  Here, in the present specification, the upper, lower, front, rear, right side, and left side as viewed from the user sitting on the toilet 12 with the back facing the wall surface WS are respectively “upper” and “lower”. , “Front”, “rear”, “right side”, and “left side”.

  The tank 14 is connected to the toilet 12 through a cleaning tube 20. The tank 14 is connected to a water supply source such as a water pipe via a water supply pipe. The tank 14 stores therein water supplied from a water supply source, and supplies the stored water to the toilet 12 as washing water in accordance with a user operation. The tank 14 is disposed above the toilet 12 and supplies washing water to the toilet 12 using gravity. The toilet 12 causes the excrement etc. of the bowl part 12b to flow into a drain pipe by the supply of the washing water from the tank.

  The support member 16 includes a toilet support part 30 that supports the toilet 12 and a tank support part 32 that supports the tank 14. The toilet bowl support part 30 supports the toilet bowl 12 so that the height from the floor surface FS can be adjusted. In other words, the toilet bowl support unit 30 supports the toilet bowl 12 so as to be movable in the vertical direction. The tank support part 32 is provided in the toilet bowl support part 30 and changes the height of the tank 14 in conjunction with the toilet bowl 12 to keep the distance between the toilet bowl 12 and the tank 14 substantially constant.

  The cabinet 18 stores the tank 14 and the support member 16. The cabinet 18 covers the tank 14 and the support member 16. In other words, the cabinet 18 is a casing or a lining. In this example, the wall surface WS to which the toilet 12 is attached is formed by the cabinet 18. In this example, the wall surface WS is, in other words, the front surface of the cabinet 18.

  In this example, the cabinet 18 is lower than the height to the ceiling of the toilet space. For example, the height of the cabinet 18 may be substantially the same as the height of the toilet space (the height from the floor surface FS to the ceiling surface).

  For example, the space in which the toilet 12 is installed and the space in which the tank 14 and the support member 16 are installed may be partitioned by a panel continuous from the floor surface FS to the ceiling surface. And the surface of this panel is good also as the wall surface WS which attaches the toilet bowl 12. FIG.

  As shown in FIG. 2, the floor finishing material 5 is provided on the floor surface FS. The floor finishing material 5 is provided, for example, in substantially the entire region outside the cabinet 18 in the floor surface FS in the toilet space. That is, the floor finishing material 5 is provided on substantially the entire area of the floor surface FS in the toilet space that is visually recognized by the user. The floor finishing material 5 may enter the cabinet 18.

  The floor finish 5 may have elasticity. For this reason, if the support member 16 is fixed on the floor finishing material 5, for example, the support performance of the toilet 12 will be lowered. For example, when the user sits on the toilet bowl 12, the toilet bowl 12 is inclined. Accordingly, the support member 16 is directly fixed on the floor surface FS.

  On the other hand, the toilet 12 is provided above the floor finish 5. For this reason, the height H1 (height of the seating surface) from the finishing surface 5a (surface) of the floor finishing material 5 to the upper surface 12a of the toilet 12 varies depending on the thickness of the floor finishing material 5. The height H1 is set to, for example, about 380 mm (370 mm or more and 440 mm or less).

  In the wall-mounted toilet unit 10, the toilet support part 30 of the support member 16 supports the toilet 12 so that the height from the floor surface FS (finished surface 5a) can be adjusted. Therefore, by adjusting the height of the toilet 12 according to the thickness of the floor finish 5, the height H1 from the finished surface 5a of the floor finish 5 to the upper surface 12a of the toilet 12 is set to a predetermined height. Can be set.

  Further, in the wall-mounted toilet unit 10, the tank support portion 32 of the support member 16 changes the height of the tank 14 in conjunction with the toilet 12 so that the distance between the toilet 12 and the tank 14 is substantially increased. Keep constant. Therefore, it is only necessary to adjust the height of the toilet 12, and the workability can be improved as compared with the case where the height of the toilet 12 and the height of the tank 14 are adjusted separately.

  Thus, in the wall-mounted toilet unit 10 according to the present embodiment, even when the height of the toilet 12 is adjustable, the workability can be improved while ensuring the cleaning performance.

  Further, in the wall-mounted toilet unit 10, since the mechanism for adjusting the height of the toilet 12 and the tank 14 is provided in the cabinet 18, the height of the toilet 12 and the tank 14 may be changed by mischief or the like. Can be suppressed.

FIG. 3 is an exploded perspective view illustrating the support member according to the embodiment.
As shown in FIG. 3, the toilet bowl support part 30 of the support member 16 includes a fixed part 34 and a movable part 36. The fixing part 34 is fixed to the floor surface FS. The movable part 36 is attached to the fixed part 34 so as to be movable in the vertical direction.

  The fixing portion 34 includes a pair of support columns 41 and 42, a pair of base plates 43 and 44, and pressing plates 45 to 48. Each support | pillar 41 and 42 and each baseplate 43 and 44 are the substantially same shapes each axisymmetric.

  The support columns 41 and 42 are plate-like members having a substantially L-shaped cross section extending in the vertical direction. The support columns 41 and 42 include front plate portions 41a and 42a, side plate portions 41b and 42b, and upper plate portions 41c and 42c. Protruding portions 41d and 42d extending rearward are provided at the lower ends of the side plate portions 41b and 42b. Through holes 41e and 42e are provided at the lower ends of the front plate portions 41a and 42a. The support columns 41 and 42 are attached to the base plates 43 and 44 with their lower ends in contact with each other, for example, by screwing them through the through holes 41e and 42e.

  Each of the front plate portions 41a and 42a is provided with two long holes 41f, 41g, 42f and 42g. The long holes 41f and 42f extend in the vertical direction. The long holes 41 f and 42 f are used for attaching the toilet 12. The long holes 41g and 42g are provided below the long holes 41f and 42f and extend in the vertical direction. The long holes 41g and 42g are used for mounting the movable portion 36.

  Through holes 41h and 42h are provided in the upper plate portions 41c and 42c. The through holes 41h and 42h are used for mounting the movable portion 36.

  The pressing plates 45 to 48 are plate-like bent into a substantially L shape. The holding plates 45 to 48 are attached to the protruding portions 41d and 42d at the lower ends of the side plate portions 41b and 42b by rivets or screws.

  The holding plates 45 to 48 are provided with through holes. The base plates 43 and 44 are provided with through holes having substantially the same shape at positions facing the through holes of the pressing plates 45 to 48. The fixing portion 34 is fixed to the floor surface FS via the through holes of the base plates 43 and 44 and the pressing plates 45 to 48. The fixing | fixed part 34 is fixed to the floor surface FS by inserting an anchor bolt in each through-hole, for example.

  The movable part 36 has a pair of frame parts 51 and 52 and a connection part 53. The frame portions 51 and 52 have substantially the same shape that is line-symmetric. The frame parts 51 and 52 are plate-shaped extending in the vertical direction, and include front plate parts 51a and 52a, upper plate parts 51b and 52b, and side plate parts 51c and 52c. The connection part 53 connects the lower ends of the frame parts 51 and 52. Thereby, the movable part 36 is formed in a substantially rectangular frame shape. The width of the movable portion 36 in the left-right direction is approximately the same as the interval between the side plate portions 41 b and 42 b of the support columns 41 and 42 of the fixed portion 34. Thereby, the movable part 36 enters between the side plate parts 41b and 42b.

  Two screw holes 51d, 51e, 52d, and 52e are provided in the front plate portions 51a and 52a. The screw holes 51d and 52d face the long holes 41f and 42f in a state where the movable portion 36 enters between the side plate portions 41b and 42b. The screw holes 51e and 52e are opposed to the long holes 41g and 42g in a state where the movable portion 36 enters between the side plate portions 41b and 42b.

  Screw holes 51f and 52f are provided in the upper plate portions 51b and 52b. The screw holes 51f and 52f are opposed to the through holes 41h and 42h in a state where the movable portion 36 is inserted between the side plate portions 41b and 42b.

  The side plate portions 51 c and 52 c are provided near the upper ends of the frame portions 51 and 52. The tank support portion 32 is attached to the movable portion 36 by, for example, being screwed to the side plate portions 51c and 52c. Thus, the tank support part 32 is attached to the toilet bowl support part 30 via the movable part 36. The method of attaching the tank support portion 32 to the movable portion 36 is not limited to the above, and any method may be used.

  The tank support portion 32 has a placement surface 32a for placing the tank 14 thereon. The mounting surface 32 a is substantially a horizontal surface in a state where the mounting surface 32 a is attached to the toilet bowl support unit 30. For example, the tank 14 is supported by the tank support portion 32 by being screwed from below while being placed on the placement surface 32a.

FIG. 4 is a rear view illustrating the toilet bowl support unit according to the embodiment.
As shown in FIG. 4, the toilet bowl support 30 further includes a pair of ball screws 55 and 56. The ball screw 55 is rotatably provided in the fixed portion 34 by being inserted into a through hole 41 h provided in the upper plate portion 41 c of the support column 41. Similarly, the ball screw 56 is rotatably provided in the fixed portion 34 by being inserted into a through hole 42 h provided in the upper plate portion 42 c of the support column 42.

  One end of each of the ball screws 55 and 56 is provided with a retaining portion having a diameter larger than that of the main body portion provided with screws on the peripheral surface. The diameter of the retaining portion is larger than the diameters of the through holes 41h and 42h. The ball screws 55 and 56 engage the upper plate portions 41c and 42c with the retaining portions while being inserted into the through holes 41h and 42h. Thereby, the ball screws 55 and 56 are rotatably supported by the support columns 41 and 42 and extend in the vertical direction. The ball screws 55 and 56 extend downward from the upper plate portions 41c and 42c.

  The movable portion 36 is connected to the fixed portion 34 via the ball screws 55 and 56 by engaging the screw holes 51f and 52f provided in the upper plate portions 51b and 52b of the frame portions 51 and 52 with the ball screws 55 and 56, respectively. The As a result, the movable portion 36 moves in the vertical direction according to the rotation of the ball screws 55 and 56.

Fig.5 (a) and FIG.5 (b) are the fragmentary sectional views showing a part of toilet bowl support part and toilet bowl which concern on embodiment.
As shown in FIGS. 4, 5 (a), and 5 (b), the screw holes 51 d and 52 d provided in the front plate portions 51 a and 52 a of the frame portions 51 and 52 of the movable portion 36 have large sizes. Bolts 61 and 62 for attaching the toilet 12 to the support member 16 are attached. The bolts 61 and 62 extend forward, and are inserted into the long holes 41f and 42f in a state where the movable part 36 is connected to the fixed part 34 via the ball screws 55 and 56. Further, the bolts 61 and 62 are inserted through openings provided in the cabinet 18 and protrude forward from the wall surface WS of the cabinet 18.

  At the rear end of the toilet 12, a pair of through holes 12c corresponding to the bolts 61 and 62 are provided. For example, the toilet 12 has bolts 61 and 62 inserted into the mounting holes 12c from the front side of the wall surface WS, and nuts 12d are attached to the bolts 61 and 62 from the front side. Then, the nut 12d is fastened to each bolt 61.62 so that a part of the toilet 12 is sandwiched between the nut 12d and the wall surface WS. Thereby, the toilet 12 is supported by the support member 16 as it was attached to the wall surface WS.

  As described above, the toilet support part 30 supports the toilet 12 in the movable part 36. Therefore, in the toilet bowl support portion 30, as shown in FIGS. 5A and 5B, the range of the long holes 41f and 42f is obtained by the vertical movement of the movable portion 36 as the ball screws 55 and 56 rotate. The height from the floor surface FS of the toilet 12 can be adjusted. Thereby, irrespective of the thickness of the floor finishing material 5, the height H1 from the finishing surface 5a of the floor finishing material 5 to the upper surface 12a of the toilet 12 can be adjusted to be substantially constant.

  Further, as described above, the tank support portion 32 is attached to the movable portion 36. Thereby, the tank support part 32 changes the height of the tank 14 in conjunction with the toilet 12. Therefore, in the wall-mounted toilet unit 10, the height of the tank 14 can be adjusted only by adjusting the height of the toilet 12. The distance between the toilet 12 and the tank 14 can be kept substantially constant.

  Thus, in the wall-mounted toilet unit 10, the heights of the toilet 12 and the tank 14 can be easily adjusted by the rotation of the ball screws 55 and 56. The height adjustment mechanism for adjusting the height of the toilet 12 and the tank 14 is not limited to the one using the ball screws 55 and 56, and may be any configuration that can adjust the height of the toilet 12 and the tank 14.

  Moreover, in the toilet bowl support part 30, the level of the movable part 36 centering on the front-back direction can be adjusted by adjusting the rotation state of each of the ball screws 55 and 56. In the toilet bowl support unit 30, for example, the distance from the upper plate portion 41c to the upper plate portion 51b and the distance from the upper plate portion 42c to the upper plate portion 52b are individually adjusted by the rotation of each of the ball screws 55 and 56. Thereby, the inclination of the movable part 36 in the left-right direction can be adjusted.

  The inclination angle of the movable portion 36 that can be adjusted by the ball screws 55 and 56 is, for example, about ± 2 ° with respect to the reference value. The reference value is a state in which, for example, the distance from the upper plate portion 41c to the upper plate portion 51b and the distance from the upper plate portion 42c to the upper plate portion 52b are substantially the same.

  In the toilet bowl support part 30, the horizontal of the toilet 12 attached to the movable part 36 can be adjusted by adjusting the horizontal with the front-rear direction of the movable part 36 as an axis. Similarly, the horizontal of the tank support part 32 attached to the movable part 36 can be adjusted by adjusting the horizontal with the front-rear direction of the movable part 36 as an axis. That is, the level of the tank 14 can be adjusted. Thereby, the adjustment for ensuring the cleaning performance of the tank 14 can be easily performed. In this example, the horizontal adjustment of the toilet 12 and the horizontal adjustment of the tank 14 can be performed simultaneously. Thereby, workability can be improved more, for example.

  In this example, a horizontal adjustment mechanism that adjusts the level of the tank support portion 32 about the front-rear direction is configured by a pair of ball screws 55 and 56. That is, in this example, the horizontal adjustment mechanism and the height adjustment mechanism are constituted by a pair of ball screws 55 and 56. In other words, the height adjustment mechanism also serves as the horizontal adjustment mechanism. The horizontal adjustment mechanism may be provided separately from the height adjustment mechanism. The horizontal adjustment mechanism may have an arbitrary configuration capable of adjusting the level of the tank support portion 32.

  In the toilet support part 30, after adjusting the height and the horizontal as described above, for example, by inserting the screws 63 and 64 from the front side into the long holes 41g and 42g and the screw holes 51e and 52e, it is movable. The part 36 is screwed to the fixing part 34. Thus, by holding the movable part 36 in the fixed part 34, it is possible to prevent the height and horizontal state of the toilet 12 and the tank 14 from changing after adjustment.

  The connecting portion 53 of the movable portion 36 is provided with a support portion 65 (see FIG. 2). The support part 65 is provided at the approximate center of the connection part 53 in the left-right direction. The support portion 65 extends forward from the connection portion 53 and protrudes forward from the wall surface WS of the cabinet 18 through an opening provided in the cabinet 18.

  As shown in FIG. 2, the support part 65 abuts on the lower part of the rear end of the toilet 12 and supports the lower part of the toilet 12 in a state where the toilet 12 is supported by the support member 16. Accordingly, the toilet 12 can be supported at three points by the pair of bolts 61 and 62 and the support portion 65 disposed at a substantially central position below the bolts 61 and 62. Thereby, for example, the inclination of the toilet 12 when the user sits on the toilet 12 can be suppressed. For example, the load on the wall surface WS can be suppressed. The support part 65 is not limited to one, and a plurality of support parts 65 may be provided in the connection part 53 or the like.

FIG. 6 is an explanatory diagram illustrating the tank according to the embodiment.
As shown in FIG. 6, the tank 14 includes a tank body 100, a water supply valve unit 102, a drive unit 104, and a jet pump mechanism 106. The tank body 100 stores cleaning water. The water supply valve unit 102 is connected to a water supply source, and switches between supply and stop of cleaning water to the tank body 100 and the jet pump mechanism 106. The drive unit 104 drives the water supply valve unit 102 according to a user's operation. The jet pump mechanism 106 supplies the flush water stored in the tank body 100 to the toilet 12 using the jet pump action by the flush water supplied from the water supply valve unit 102.

  A water supply pipe 110 and a water supply pipe 112 are connected to the water supply valve unit 102. The water supply pipe 110 is connected to a water supply source. The water supply pipe 110 is a flexible pipe, for example. Thereby, workability can be improved. In addition, as the water supply pipe 110, for example, a water supply pipe having a general size of 15A can be used. Thereby, for example, workability can be improved during remodeling from a low-tank toilet device.

  Between the water supply valve unit 102 and the primary side water supply pipe 110, a constant flow valve 114 for providing a constant flow rate of the cleaning water supplied to the water supply valve unit 102 is provided. Further, a vacuum breaker valve 116 is provided between the water supply valve unit 102 and the secondary side water supply pipe 112. The vacuum breaker valve 116 sucks air from the outside to prevent negative pressure in the water supply pipe 112.

  The water supply valve unit 102 moves the main valve body 120 relative to the main valve seat 122 by the main valve body 120 that is a pilot diaphragm valve, the main valve seat 122 on which the main valve body 120 is seated, and the internal pressure. And a pressure chamber 124. The main valve body 120 switches between a water stop state in which the main valve seat 120 is seated and stopped and a water supply state in which the water is supplied away from the main valve seat 122.

  The pressure chamber 124 includes a first hole 124a and a second hole 124b that release pressure in the pressure chamber 124, a poppet valve 126 that opens and closes the first hole 124a, a pilot valve 128 that opens and closes the second hole 124b, Have The opening area of the first hole 124a is larger than the opening area of the second hole 124b. The first hole 124a is provided above the second hole 124b.

  The poppet valve 126 is connected to the drive unit 104 and is driven by the drive unit 104 to open and close the first hole 124a. The pilot valve 128 is connected to the feed water float 130. The water supply float 130 moves up and down with the level of the cleaning water in the tank body 100. The pilot valve 128 opens and closes the second hole 124b according to the vertical movement of the water supply float 130.

  The main valve body 120 is provided with a bleed hole (not shown). The pressure chamber 124 communicates with the primary flow path 102a through this bleed hole. When the first hole 124a and the second hole 124b are closed, the water pressure in the pressure chamber 124 becomes the same as the water pressure in the primary channel 102a through the bleed hole. Further, the secondary channel 102b is open to the atmosphere. For this reason, the area where the water pressure acts on the main valve body 120 is larger than the area of the primary side flow path 102a, so the main valve body 120 is pressed against the main valve seat 122 and closes. Thereby, when the 1st hole 124a and the 2nd hole 124b are obstruct | occluded, it will be in a water stop state.

  On the other hand, when the first hole 124a and the second hole 124b are opened, the washing water flows out from the pressure chamber 124, and the pressure in the pressure chamber 124 decreases. As a result, the main valve body 120 moves away from the main valve seat 122 and opens to enter a water supply state.

  The drive unit 104 includes a drive unit 140 and a transmission mechanism 142. The drive unit 140 includes, for example, a gear motor and operates in response to a user operation signal input from a remote controller or the like. The transmission mechanism 142 is connected to the driving unit 140 and transmits the driving force of the driving unit 140 to the poppet valve 126. The transmission mechanism 142 is, for example, a rotational drive shaft, and transmits the rotational driving force to the poppet valve 126. The poppet valve 126 opens and closes the first hole 124 a by the driving force supplied from the driving unit 140. In this way, the drive unit 104 switches the opening and closing of the first hole 124a by driving the drive unit 140 in accordance with a user operation instruction.

  Further, the drive unit 104 has an operation lever 144. The operation lever 144 is connected to the transmission mechanism 142 and the emergency manual operation unit 146. The manual operation unit 146 includes an operation unit 146a, a movable unit 146b, and a connection unit 146c.

  The operation unit 146 a is provided outside the cabinet 18. The operation unit 146a has, for example, a ring shape that allows a user to perform a pulling operation. The movable part 146b is connected to the operation part 146a via the connecting part 146c. The movable portion 146b moves according to the pulling operation of the operation portion 146a by the user, and transmits the operation driving force to the operation lever 144.

  As described above, the manual operation unit 146 transmits the operation driving force of the operation unit 146a to the transmission mechanism 142 via the connection unit 146c, the movable unit 146b, and the operation lever 144, and thus according to the manual operation of the user. The opening and closing of the first hole 124a by the poppet valve 126 can be switched. Thereby, for example, even in an emergency such as a power failure (when the drive unit 140 does not operate), the wash water can be supplied from the tank 14 to the toilet 12. The configuration of the manual operation unit 146 and the operation mode of the user are not limited to the above, and may be any configuration and mode that can control the opening and closing of the poppet valve 126 from the outside of the cabinet 18.

  The jet pump mechanism 106 includes a throat pipe 150, a jet nozzle 152, and a flow path switching unit 154. The throat pipe 150 is disposed on the downstream side of the water supply pipe 112 on the secondary side. The jet nozzle 152 is connected to the downstream end of the secondary water supply pipe 112. The jet nozzle 152 induces a jet pump action by injecting cleaning water toward the throat pipe 150.

  The channel switching unit 154 includes a channel switching valve 154a and a float 154b. The flow path switching valve 154 a switches between a flow path in which the direction in which the cleaning water sprayed from the jet nozzle 152 travels is directed toward the inside of the throat pipe 150 and a flow path in which the flow direction is directed toward the outside of the throat pipe 150. The float 154b moves up and down according to the level of the wash water stored in the tank body 100, thereby operating the flow path switching valve 154a.

  The throat pipe 150 has an ascending pipe part 150a extending obliquely upward from below and a descending pipe part 150b extending downward from the vicinity of the upper end of the ascending pipe part 150a. The throat pipe 150 has a generally inverted V shape. A suction port 150c is provided at an upstream end (inlet part) of the rising pipe part 150a of the throat pipe 150. The suction port 150 c is located at the lower part of the tank body 100.

  An outlet portion of the descending pipe portion 150 b of the throat pipe 150 is connected to a drain port 100 a provided on the bottom surface of the tank body 100. The drain port 100 a is connected to the cleaning pipe 20. Thereby, the wash water stored in the tank body 100 is supplied to the toilet 12 via the jet pump mechanism 106.

  The jet nozzle 152 is disposed to face the suction port 150 c of the throat pipe 150. For example, the suction port 150c and the jet nozzle 152 of the throat pipe 150 are constantly submerged in the tank body 100 in a normal use state.

  When toilet flushing is started, the jet pump mechanism 106 injects wash water from the jet nozzle 152 toward the suction port 150 c of the throat pipe 150. At this time, the space near the suction port 150c in the throat pipe 150 close to the jet nozzle 152 becomes negative pressure. By inducing a jet pump action (ejector effect) by this negative pressure, the cleaning water in the vicinity of the tank body 100 is sucked into the throat pipe 150. In the jet pump mechanism 106, the wash water sucked by the jet pump action and the wash water ejected from the jet nozzle 152 flow together in the throat pipe 150, pass through the drain port 100a, and the water conduit of the toilet 12 (Not shown).

  Note that the term “jet pump action” described in the present specification refers to the flow of cleaning water itself having a momentum injected from the jet nozzle 152 toward the suction port 150c of the throat pipe 150. Without depending on other mechanical elements, a negative pressure is formed so as to directly draw the cleaning water in the vicinity of the suction port 150c of the throat pipe 150, and the like, and the inside of the throat pipe 150 is utilized by using this negative pressure. This means that the wash water in the tank body 100 sucked into the tank is pumped to the toilet 12 side.

Next, the operation of the tank 14 will be described.
In the standby tank 14, the level of the cleaning water in the tank main body 100 is, for example, WL1 shown in FIG. At this time, in the water supply valve unit 102, both the first hole 124a and the second hole 124b of the pressure chamber 124 are closed, and the main valve body 120 is seated on the main valve seat 122 and is in a water stop state. ing.

  When performing toilet cleaning of the toilet 12, the user inputs a toilet cleaning operation signal to the drive unit 140 via a remote controller (not shown). The driving unit 140 operates in response to the input of the operation signal, and transmits the driving force to the poppet valve 126 via the transmission mechanism 142. The poppet valve 126 changes from the closed state to the open state in response to the driving force supplied from the driving unit 140, and opens the first hole 124a.

  When the first hole 124a is opened, the main valve body 120 of the water supply valve unit 102 is separated from the main valve seat 122 and enters a water supply state. As a result, the wash water supplied from the external water supply source reaches the jet nozzle 152 via the primary water supply pipe 110, the constant flow valve 114, the water supply valve unit 102, and the secondary water supply pipe 112. Wash water is jetted from the nozzle 152 toward the suction port 150 c of the throat pipe 150.

  When cleaning water is jetted from the suction port 150 c of the throat pipe 150 into the throat pipe 150, the vicinity of the suction port 150 c becomes negative pressure, and the cleaning water stored in the tank body 100 is also sucked into the throat pipe 150. . Then, the wash water supplied from the water supply source and the wash water in the tank body 100 flow together in the throat pipe 150 and are supplied to the toilet 12. Thereby, toilet cleaning of the toilet 12 is started.

  Immediately after the supply of cleaning water from the water supply valve unit 102 to the water supply pipe 112 on the secondary side is started, the water level of the cleaning water in the tank body 100 is near the water level WL1, and the flow path switching unit 154 The float 154b is in a raised state. Accordingly, the flow path switching valve 154a is lowered, and the front side of the jet nozzle 152 is opened. As a result, the cleaning water sprayed from the jet nozzle 152 flows through the throat pipe 150.

  When the toilet bowl cleaning is continued, the water level in the tank main body 100 is lowered, and the water supply float 130 of the water supply valve unit 102 is lowered. When the descent of the feed water float 130 is started, the pilot valve 128 is operated and the second hole 5124b is opened. At this time, the first hole 124a is in a closed state, but the second hole 124b is kept open until the water supply float 130 rises again. When the second hole 124b is opened, the water supply state in the water supply valve unit 102 is continued regardless of the open / closed state of the first hole 124a.

  When the water level in the tank body 100 is lowered, the float 154b of the flow path switching unit 154 is also lowered in conjunction with the lowering of the water level. When the water level in the tank main body 100 is lowered to the water level WL2 and the float 154b is also lowered to the position of the water level WL2, the flow path switching valve 154a is raised.

  When the flow path switching valve 154a rises, the washing water jetted from the jet nozzle 152 is blocked by the flow path switching valve 154a. Thereby, the washing water sprayed from the jet nozzle 152 is rebounded by the flow path switching valve 154a without flowing into the throat pipe 150. That is, when the flow path switching valve 154a rises, the traveling direction of the cleaning water sprayed from the jet nozzle 152 is switched from the inner direction of the throat pipe 150 to the outer direction of the throat pipe 150 and is stored in the tank body 100. The When the flow path switching valve 154a rises, the washing water does not flow to the throat pipe 150, and the supply of the washing water to the toilet 12 is also stopped.

  At this time, the water level in the tank body 100 rises, but the flow path switching valve 154a is held in a raised state by the momentum of the washing water. The float 154b is also held in that position without rising.

  On the other hand, the water supply float 130 of the water supply valve unit 102 rises in conjunction with the rise of the water level in the tank body 100. Until the water level in the tank body 100 reaches the water level WL1, the second hole 124b remains open, and the water supply state by the water supply valve unit 102 is thereby continued.

  When the water level in the tank body 100 rises and reaches the water level WL1, the water supply float 130 of the water supply valve unit 102 also rises to the position of the water level WL1, the pilot valve 128 operates in the water supply valve unit 102, and the second The hole 124b is closed. As a result, the pressure in the pressure chamber 124 becomes the primary flow path pressure, the main valve body 120 moves toward the main valve seat 122, and finally the valve is closed (water stoppage state). The water supply valve unit 102 is in a water stop state, water supply into the tank body 100 is finished, and toilet flushing is finished.

  As described above, in the tank 14, the wash water supplied from the water supply source and the wash water stored in the tank body 100 are supplied together to the toilet 12. Therefore, in the tank 14, for example, the capacity of the cleaning water stored in the tank body 100 in advance may be reduced as compared with a tank (so-called low tank) that supplies the cleaning water to the toilet 12 using only gravity. it can. For example, while the storage capacity of the low tank is about 13 liters, the tank 14 can be reduced to about 4.8 liters.

  Thereby, the tank 14 can be reduced in size compared with a low tank. For example, the height of the tank 14 can be suppressed and the cabinet 18 can be made compact. In addition, the weight of the tank 14 can be reduced, and the tank 14 can be easily supported by the support member 16. For example, workability in height adjustment and the like can be improved.

  Further, the tank 14 having the jet pump mechanism 106 is supplied from the water supply source by sucking the cleaning water stored in the tank main body 100 using the water supply pressure of the water supply source without requiring electric power or the like. The flow rate of the cleaning water supplied to the toilet 12 can be amplified more than the flow rate of the cleaning water.

  Furthermore, in the tank 14, by suppressing the water storage capacity, the time required for water supply into the tank body 100 can be shortened compared to the low tank. That is, it is possible to shorten the time until the next toilet bowl cleaning can be started after the toilet bowl cleaning is performed.

  The tank 14 is not limited to the tank having the jet pump mechanism 106, and may be a tank (low tank) for supplying cleaning water to the toilet 12 using only gravity.
