Description

  The present invention relates to a body washing unit for a toilet that can be easily attached to and installed in an existing toilet.

  The applicant previously proposed a simple body washing unit that can be attached to an existing toilet and can automatically wash the anus after excretion with warm water (Patent Document 1).

  In this case, a case body 1 having a support frame 2 is assembled between a toilet body B1 of an existing toilet bowl, a toilet seat B2 and a toilet seat lid B3 (FIG. 11). The nozzle 4 is incorporated. The support frame 2 is formed in substantially the same shape as the upper edge of the toilet body B1, and the case body 1 uses the bolts B4 and B4 for attaching the toilet seat B2 and the hinges B5 and B5 for the toilet seat lid B3. Can be attached to the rear of B1.

  The case body 1 is interposed between the mixing valve 1a connected to the external cold water source C and the hot water source H, and the mixing valve 1a and the hot water nozzle 3 in order to eject hot water of an appropriate temperature from the hot water nozzle 3. An on-off valve 1b and a drain pipe 1d with a drain valve 1c branched from between the mixing valve 1a and the on-off valve 1b are incorporated (FIG. 12). The case body 1 incorporates an electric warm air heater (not shown) for ejecting warm air from the warm air nozzle 4, and the warm water nozzle 3 and the warm air nozzle 4 are projected into the toilet body B 1. A drive motor (not shown) that incorporates them into the case body 1 while being integrated is incorporated.

Therefore, when the user sits on the toilet seat B2, the mixing valve 1a, the on-off valve 1b, and the drain valve 1c are opened, and the cold water in the pipeline is discharged into the toilet through the drain pipe 1d. Further, after excretion, by giving a washing start command, the mixing valve 1a and the opening / closing valve 1b are opened, the anus is washed with hot water from the hot water nozzle 3, and then the anus is washed with hot air from the hot air nozzle 4. Can be dried. The hot water nozzle 3 and the hot air nozzle 4 protrude from the case body 1 into the toilet body B1 only when in use, and are stored in the case body 1 when not in use.
JP 2004-308230 A

  When such a conventional technique is used, the hot water nozzle 3, the hot air nozzle 4, and the accompanying valves, the hot air heater, the drive motor, etc. need to be housed in the case body 1 in a compact manner. There is a problem that the above-mentioned restrictions are large and the manufacturing cost tends to be excessive. This is because the case body 1 is interposed between the toilet body B1, the toilet seat B2, and the toilet seat lid B3, so that the allowable size is severely limited.

  Therefore, in view of the problems of the prior art, the object of the present invention is to provide a warm water nozzle in the toilet and a motor that drives the hot water nozzle to a standby position and a use position, thereby increasing the degree of freedom in design and production. An object of the present invention is to provide a body washing unit for a toilet that can improve practicality.

  The configuration of the present invention for achieving such an object includes a hot water nozzle installed inside a toilet, a motor for driving the hot water nozzle to a downward standby position and an upward use position, installed outside the toilet, A hot water nozzle that is connected to the inside and outside of the toilet and is rotatably connected to the tip of the first pipe and is driven to rotate forward and backward by a motor. The second pipe and a third pipe that is rotatably connected to the lower end of the second pipe and rotates while rotating by the second pipe, and is held inside the toilet. Prior to use, the gist is to discharge the cold water in the pipe line from the hot water nozzle at the standby position into the toilet. However, in the present invention, downward and upward include diagonally downward and diagonally upward.

  According to the configuration of the invention, the hot water nozzle is installed inside the toilet bowl, and the supply unit that supplies the hot water to the hot water nozzle is installed outside the toilet bowl. A motor for driving the hot water nozzle to the standby position and the use position is installed outside or inside the toilet. Therefore, the hot water nozzle, the motor, and the supply unit have no extreme restrictions on the size and shape of each, and the practicality can be improved by increasing the degree of freedom in design. The supply unit discharges the cold water in the pipe line into the toilet through the hot water nozzle in the downward standby position, and replaces the cold water in the pipe line with hot water, so provide a special drain valve or drain pipe. And discomfort caused by cold water can be eliminated.

  The hot water nozzle held inside the toilet bowl through the first pipe to the third pipe rotates up and down while turning horizontally through the third pipe by rotating the second pipe through the motor, It can be easily driven between a downward standby position and an upward use position. However, the standby position at this time is, for example, a position facing the front of the toilet, and the use position is a position in a direction crossing the toilet. In order to rotate the third tube by rotating the second tube, for example, the gear on the third tube connected at right angles to the lower end of the second tube is engaged with the fixed gear, or When the second tube is rotated and the third tube is swung horizontally by connecting both ends of the stretchable cord-like body that winds and fixes the intermediate portion onto the third tube to the fixing member, the second tube is rotated accordingly. Rotate 3 tubes.

  The hot water nozzle, which is held inside the toilet bowl through a holding pipe that rotatably penetrates the wall surface of the toilet bowl, rotates the holding pipe via a motor installed outside the toilet bowl so that it can be used in a downward standby position and upward. Can be driven into position. However, the standby position and the use position mentioned here are substantially the same position, and the posture of the hot water nozzle simply changes upward and downward. In addition, it is preferable that a holding | maintenance pipe seals the penetration part of a wall surface watertightly, for example via the bush with a suitable seal. On the other hand, if the holding tube is connected to the tip of the first tube communicating with the inside and outside of the toilet and the holding tube is rotationally driven by the motor in the toilet, the first tube can be rotated without passing through the wall surface of the toilet. The operation mode can be easily realized.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The body washing unit for the toilet includes a hot water nozzle 11 installed in the toilet B, a motor M installed outside the toilet B, and a supply unit 20 installed outside the toilet B (FIG. 1, FIG. 1). 2). However, FIG. 1 (A) and FIG. 1 (B) are main part perspective views showing that the hot water nozzle 11 is at a diagonally downward standby position and an obliquely upward use position, respectively. The motor M is housed and installed in the case M1 on one side outside the toilet B.

  The toilet bowl B includes a toilet bowl body B1 and a toilet seat B2 attached to the toilet bowl body B1 via hinges B5 and B5. A toilet seat lid B3 (not shown) is attached on the toilet seat B2 via hinges B5 and B5. Spacers B2a, B2a,... Are mounted on the lower surface of the toilet seat B2.

  The hot water nozzle 11 is held in the toilet bowl B via the first pipe 31, the second pipe 32, and the third pipe 33 (FIGS. 1 and 3). The first pipe 31 is installed across the upper edge of one side of the toilet body B1 via the bracket 31b. The bracket 31b can be fixed by being elastically fitted to the upper edge of the toilet body B1, for example, on one side of the toilet body B1 on the side where the motor M is installed. The second pipe 32 is connected to an elbow-shaped rotary joint 31a at the tip of the first pipe 31 so as to be rotatable downward. The third pipe 33 is rotatably connected to an elbow-shaped rotary joint 32 a at the lower end of the second pipe 32. Furthermore, an elbow-shaped hot water nozzle 11 is attached to the tip of the third pipe 33.

  A chain sprocket 35a is fixed in the middle of the second pipe 32, and the chain sprocket 35a and the chain sprocket 35b at the shaft end of the motor M are crossed across the upper edge of the toilet body B1. 35 is wound. However, the chain 35 only needs to be able to rotate the second pipe 32 forward and backward by the motor M, and may be replaced with a timing belt, a friction belt, or an appropriate gear. The first pipe 31 and the chain 35 are appropriately configured so as to cross the upper edge of the toilet body B1 within the height of the spacers B2a, B2a..., Hinges B5, B5 on the lower surface of the toilet seat B2. For example, the first tube 31 may be a flat tube that is thin at the top and bottom at least on the upper edge of the toilet body B1. Further, the spacers B2a, B2a,... May be provided in the support frame 2 of FIG. 11 and notches corresponding to the first pipe 31 and the chain 35 may be provided in the support frame 2.

  A downward gear 36a is attached to the lower portion of the second pipe 32 so as to be relatively rotatable. The gear 36a is fixed to the elbow-shaped rotary joint 31a via a plurality of support rods 36b, 36b. On the other hand, a gear 36c that meshes with the gear 36a is fixed to the base portion of the third pipe 33 so as not to be relatively rotatable.

  Therefore, when the second pipe 32 is rotated forward and backward via the motor M, the third pipe 33 can be turned horizontally via the elbow-shaped rotary joint 32a, and at this time, via the gears 36a and 36c. Then, the third pipe 33 is rotated, and the hot water nozzle 11 can be driven downward and upward. For example, when the hot water nozzle 11 is in the downward standby position (solid line in FIG. 3, FIG. 1 (A)), if the second pipe 32 is rotated by about 90 ° in the direction of the arrow K1 in FIG. In the same direction, it turns horizontally by the same angle (in the direction of arrow K2 in FIG. 3). It can be driven by the two-dot chain line in the figure, FIG. In order to return the hot water nozzle 11 at the use position to the standby position, the second pipe 32 may be rotated about 90 ° in the reverse direction via the motor M.

  1A and 1B, the hot water nozzle 11 is positioned substantially in front of the toilet bowl B and in a direction crossing the toilet bowl B, respectively. Therefore, the rotation angle of the second pipe 32 by the motor M may be set to about 90 °, but may be set to any other appropriate angle. Further, in order to change the posture of the hot water nozzle 11 between diagonally downward at the standby position and diagonally upward at the use position, the gear 36a, 36c has a gear ratio of 1 and the third angle by the same angle as the rotation angle of the second pipe 32. The pipe 33 may be rotated, but the third pipe 33 can be rotated by an angle different from the rotation angle of the second pipe 32 by changing the gear ratio of the gears 36a and 36c to other than 1.

  On the other hand, the gears 36a and 36c in FIG. 3 are partial gears that form teeth only at about 1/3 of the circumference, assuming that the rotation angle of the second tube 32 and the third tube 33 is about 90 °. However, teeth may be formed around each circumference. The gears 36a and 36c may be arbitrary cross shaft gears including a bevel gear, and one tooth is replaced with an engaging pin so that the gear 36a and 36c can rotate smoothly even if some dirt is attached to the other tooth. The backlash may be increased by engaging the engagement pin.

  The supply unit 20 is configured by cascading a mixing valve 21 that combines control valves 21a and 21b and an on-off valve 22 (FIG. 2). The inlet side of one control valve 21 a is connected to the cold water source C, and the inlet side of the other control valve 21 b is connected to the cold water source C via the heater unit 23. The outlet side of the on-off valve 22 is connected to the first pipe 31 for the hot water nozzle 11. In addition, the heater unit 23 can heat the water flowing in from the inlet side during the operation, and can keep the hot water temperature on the outlet side at an appropriate temperature. The supply unit 20 is installed as a floor-mounted type or a wall-mounted type at an appropriate place in the toilet.

  Such a toilet body washing unit operates, for example, as shown in FIG. However, before use (time t <t0 in FIG. 4), the hot water nozzle 11 is waiting at the downward standby position, and the control valves 21a and 21b and the on-off valve 22 of the mixing valve 21 are all fully closed. It is assumed that the heater unit 23 is not operating.

  When the user is seated on the toilet seat B2 (time t = to in FIG. 4; hereinafter referred to simply as (t = to)), a sensor (not shown) is activated to activate the heater unit 23 and the mixing valve 21. By opening the control valves 21a and 21b at appropriate opening degrees and further opening the on-off valve 22, prior to the use of the hot water nozzle 11, the cold water in the pipe line after the mixing valve 21 is moved downward. To the toilet B (t = t0 to t1). The mixing valve 21 mixes water from the cold water source C and hot water from the heater unit 23 through the control valves 21a and 21b to create hot water having an appropriate temperature, and the control valves 21a and 21b are connected to the hot water nozzle 11. It shall automatically open to an opening that is adjusted and set in advance so that hot water of appropriate temperature and water pressure is injected. When the time t = t1 and all the cold water in the pipe after the mixing valve 21 is discharged and replaced by the hot water from the mixing valve 21, the on-off valve 22 is closed and waiting (t> t1). It should be noted that a simple timer control is sufficient for the control from time t = to to t1.

  When a user who has excreted operates a switch (not shown) to give a washing start command (t = t2), the motor M is activated to drive the hot water nozzle 11 to the upward use position (t = t2 to t3). . Subsequently, the on-off valve 22 is opened (t = t3), the anus can be washed with hot water sprayed from the hot water nozzle 11 (t = t3 to t4), and then a stop command is operated by operating a switch (not shown). (T = t4), the on-off valve 22 is closed and the cleaning operation is completed. At the same time, the heater unit 23 is stopped, the control valves 21a and 21b are closed, and the hot water nozzle 11 is returned to the original standby position via the motor M (t = t4 to t5) to complete a series of operations.

  In the above description, the heater unit 23 may be provided outside the supply unit 20, and may be omitted when an external hot water source H is available as shown in FIG. Further, the mixing valve 21 may be an integral type like the mixing valve 1a of FIG.

Other embodiments

  The hot water nozzle 11 is placed in a downward standby position (in FIG. 5) via a flexible cord 37 that can be expanded and contracted by springs 37a and 37a at both ends, instead of via the gears 36a and 36c. It can be driven between an alternate use position (two-dot chain line in the figure). Note that the solid line in the figure indicates an intermediate position between the standby position and the use position.

  A fan-shaped bracket 37 b is fixed to the elbow-shaped rotary joint 31 a at the tip of the first pipe 31. Further, both ends of the cord-like body 37 are respectively engaged with corners of both ends of the bracket 37b via springs 37a, and an intermediate portion is hung so as to be wound around the third tube 33, and a third point is fixed at the fixing point 37c. It is being fixed to the outer periphery of the pipe | tube 33 (FIG. 6). 5 and 6, the locking points of the springs 37 a and 37 a on the bracket 37 b are located on both outer sides of the horizontal turning range of the third tube 33 due to the rotation of the second tube 32. Further, the arrow on the third pipe 33 in FIG. 6 indicates the direction of the hot water nozzle 11.

  When the hot water nozzle 11 is in the downward standby position, the second pipe 32 is rotated via the motor M (in the direction of arrow Ko in FIG. 5), and the third pipe 33 is turned horizontally toward the use position (FIG. 6). The direction of the arrow K1), one of the springs 37a, 37a is pulled and the third pipe 33 rotates (in the direction of the arrow K2 in the figure), and the hot water nozzle 11 is driven to the upward use position via the intermediate position. Can do. When returning the hot water nozzle 11 from the upward use position to the downward standby position, the second pipe 32 may be rotated in the reverse direction via the motor M. On the outer periphery of the third pipe 33, an engagement pin 33a that engages with a notch 32b at the tip of an elbow-shaped rotary joint 32a is erected (FIG. 7). The engagement pin 33a and the notch 32b Can define the rotation range of the third pipe 33 and can define the direction of the hot water nozzle 11 at the standby position and the use position.

  5 and 6, the cord 37 with springs 37a and 37a is divided into two cords 37 and 37 with springs 37a from one locking point on the bracket 37b to the fixing point 37c, respectively. May be. Further, the separate spring 37a may be omitted by making the cord-like body 37 itself a stretchable rubber string, rubber belt, rubber band or the like. The rotation angle range of the third pipe 33 by the engagement pin 33a and the notch 32b may be set to be the same as or different from the rotation angle of the second pipe 32 by the motor M.

  On the upper edge of the toilet body B1 of the toilet bowl B, a hot air duct 12 that opens the front and rear hot air outlets 12a and 12b obliquely upward can be attached (FIG. 8). However, in FIG. 8, the hot water nozzle 11 is illustrated in FIG. 3 or FIG.

  The hot air duct 12 is formed in substantially the same shape as the upper edge of the toilet body B1, and includes a rear portion of the upper edge of the toilet body B1, a side portion on one side where the first pipe 31 and the hot water nozzle 11 are not installed, It is continuous with the department. In addition, spacers 12c and 12d having the same height as the hot air duct 12 are attached to the side of the first pipe 31 and the hot water nozzle 11 side, and the spacers 12c and 12d also position the first pipe 31 and the bracket 31b. Except for this, the overall shape is substantially the same as that of the toilet body B1. Connected to the rear end of the hot air duct 12 is a hot air heater 12e that uses, for example, a hair dryer. However, the warm air heater 12e may be any other electric heater.

  After washing the anus with hot water from the hot water nozzle 11, when a hot air heater 12 e is operated by operating a switch (not shown), the hot air from the front and rear hot air outlets 12 a and 12 b includes the local area including the anus. Can be dried. The hot air heater 12e is stopped via a switch (not shown) after drying. The warm air duct 12 and the spacers 12c and 12d are arranged such that the first pipe 31 and the like cross the upper edge of the toilet bowl B together with the spacers B2a, B2a... On the lower surface of the toilet seat B2 or instead of the spacers B2a, B2a. In addition, the toilet seat B2 can be stably seated on the upper edge of the toilet body B1. However, in FIG. 8, the hot air outlets 12 a and 12 b may be provided only on either the front or rear instead of being provided on the front or rear.

  The hot water nozzle 11 can be held in the toilet body B1 via a holding tube 34 that passes through the rear wall surface of the toilet body B1 so as to be rotatable inward and outward (FIG. 9).

  The hot water nozzle 11 is mounted obliquely at the tip of the holding tube 34, and by rotating the holding tube 34 via the motor M, the hot water nozzle 11 is tilted downward in the standby position (two-dot chain line in the figure) and diagonally upward. It can be driven during the use position (solid line in the figure). The base of the holding pipe 34 is connected to the on-off valve 22 of the supply unit 20 via the rotary joint 34a and the first pipe 31 outside the toilet body B1, and the holding pipe 34 is connected via gears 35c and 35d. The motor M is connected. However, the gears 35c and 35d may be replaced with an arbitrary power transmission mechanism such as a chain, a timing belt, and a rubber belt, and the rotation direction of the holding tube 34 by the motor M may be one direction, and may be a forward or reverse direction. There may be. Further, it is preferable that the penetration portion of the holding tube 34 with respect to the toilet body B1 seals the inside and outside of the toilet body B1 in a watertight manner by using, for example, a sleeve with a seal through which the holding tube 34 is inserted.

  The hot water nozzle 11 of FIG. 1, FIG. 3 or FIG. 5 can be attached to one side of the Japanese-style toilet bowl B (solid line in FIG. 10). However, in the same figure, the 1st pipe | tube 31 is piping by the back side of the toilet bowl B, for example via the elbow 31c so that a user may not be disturbed. The first pipe 31 can be piped forward of the toilet bowl B. Moreover, the hot water nozzle 11 of FIG. 9 can also be attached to the rear part of the Japanese-style toilet bowl B (two-dot chain line of FIG. 10). At this time, the holding tube 34 may penetrate the toilet bowl B inward and outward, or may be rotatably installed via a sleeve (not shown) so as to cross the upper edge of the toilet bowl B. Furthermore, the hot air duct 12 of FIG. 8 is applicable also to FIG. 9, FIG.

  In the above description, the motor M can be installed in the toilet body B1. Further, the motor M in the toilet body B1 has a second pipe 32 or a holding pipe 34, which is a rotational drive target, provided in the shaft of the rotor, and, for example, by fixing the stator following the gear 36a in FIG. The entire configuration can be summarized in a compact manner. The motor M is installed in the toilet body B1, and the first pipe 31 shown in FIGS. 1, 3 or 5, and 9 can be passed through the wall surface of the toilet body B1 so as to communicate with the inside and outside of the toilet B. . The same applies to the Japanese style toilet B in FIG. In either case, since it is not necessary to allow the pipe material to rotate freely through the wall surface of the toilet body B1 or the toilet bowl B, a watertight seal can be easily realized.
