Description

  TECHNICAL FIELD The present invention relates to a sanitary washing toilet seat device and a toilet device, and more specifically to a sanitary washing toilet seat device for washing a user's “butt” or the like seated on a Western-style sitting toilet with water and a toilet device equipped with the same.

  Since the sanitary washing toilet seat apparatus accommodates a washing nozzle for injecting washing water in its interior so as to be able to advance and retreat, a mainstream one is a type that is installed and used at the upper rear part of a seated toilet. And in order to move the cleaning nozzle forward and backward, and to provide a odor suction port in the sitting toilet bowl, the front of the main body case constituting the sanitary cleaning toilet seat device extends to the bowl side of the sitting toilet, and a part of the bowl opening is It is supposed to be closed.

However, when the main body case extends to the bowl side in this way, the back side and the like easily become dirty. On the other hand, in order to improve the cleaning property, for example, a structure in which the extending part of the main body case is detachable is disclosed (for example, Patent Documents 1 and 2).
Japanese Patent Publication No. 5-74656 JP-A-6-167041

  However, it is troublesome to remove the extended portion one by one during cleaning, and there is a problem that the extended portion is accidentally dropped into the water pool of the bowl when attaching or detaching.

  In order to solve such a problem, it is preferable that the main body case of the sanitary washing toilet seat apparatus is set backward so as not to cover the bowl of the sitting toilet. However, since a normal toilet bowl requires a low tank, flush valve, etc. to be installed close to the rear, if the front of the case is retracted so that the case does not cover the bowl, the depth of the case will decrease. End up. When the depth of the case becomes small, there arises a problem that the effective accommodation volume in the case becomes small.

  The present invention has been made on the basis of recognition of such problems, and by making a minimal change to the main body configuration of the sanitary washing toilet seat device, dirt is less likely to adhere, easy to clean, and neat appearance.

FIG. 6 is a schematic cross-sectional view for explaining advance and retreat of the cleaning nozzle in the sanitary washing toilet seat device of this example.
That is, FIG. 10A shows a state in which the cleaning nozzle is housed in the sanitary washing toilet seat apparatus body 500, and FIG. 10B shows a state in which the cleaning nozzle has advanced into the bowl 310.
The cleaning nozzle 530 is provided in a first cylinder 534 provided on the mounting base 532, a second cylinder 536 provided slidably in the first cylinder, and provided slidable in the second cylinder. A third cylinder 538. A water discharge port (not shown) is provided near the tip of the third cylinder 538 so that water can be jetted toward the “butt” of the user.

  As shown in FIG. 6A, the cleaning nozzle 530 is accommodated in the second cylinder 536, the second cylinder 536 is accommodated in the first cylinder 534, as shown in FIG. The first cylinder 534 is in a position retracted backward on the mounting base 532.

  On the other hand, in the use state, as shown in FIG. 6B, the first cylinder 534 advances forward on the mounting base 532, and the second cylinder 536 and the third cylinder 538 advance forward. To do. The closing plate 525 is normally biased to a position where the opening 520 is closed by a spring (not shown) or the like. Then, as shown in FIG. 6B, when the cleaning nozzle 530 advances forward, it is pushed by the cleaning nozzle and opens against the urging force. Further, as will be described in detail later, the closing plate 525 may be opened and closed using an actuator or the like.

  According to this specific example, the washing nozzle 530 is of a three-stage type, so that it can be compactly accommodated in the sanitary washing toilet seat device body 500 in the housed state, while the user's “tail” in the state of use. Can be advanced to a predetermined position for cleaning. In particular, in the present embodiment, as described above with reference to FIGS. 1 to 4, the front surface of the sanitary washing toilet seat apparatus body 500 does not cover the bowl 310, and is substantially continuous with or more than the curved side wall surface of the opening of the bowl 310. It is provided to recede backward (in a direction away from the bowl 310). Therefore, it is necessary to shorten the depth of the sanitary washing toilet seat apparatus body 500 (the length in the left-right direction in FIG. 6). On the other hand, the washing nozzle of this specific example can be stored compactly as shown in FIG. 6A by adopting a three-stage structure, and the sanitary washing toilet seat with a limited depth. It can be built in the apparatus main body 500. Further, by making the cleaning nozzle 530 into a three-stage type, the water outlet at the tip of the cleaning nozzle 530 is advanced sufficiently far from the front surface 510 of the sanitary cleaning toilet seat apparatus body 500, and the cleaning water is reliably jetted to the “buttock” or the like. Can do.

Next, a sanitary washing toilet seat device according to a second specific example of the embodiment of the present invention will be described.
FIG. 7 is a schematic perspective view of a sanitary washing toilet seat device of a second specific example of the present embodiment.
That is, the sanitary washing toilet seat apparatus main body 500 is installed on the flat surface 300F on the upper rear side of the sitting toilet 300, and the toilet seat 410 is attached. Further, an openable / closable toilet lid may be further provided on the toilet seat 410.

FIG. 8 is a schematic perspective view showing a state in which the toilet seat 410 is removed from the sanitary washing toilet seat device.
Also in this specific example, the sanitary washing toilet seat apparatus body 500 is installed on the flat surface on the upper rear side of the flush toilet stool 300, and its front surface 510 is curved along the edge of the bowl 310 of the stool toilet 300. The curved front surface 510 is not perpendicular to the upper flat surface 300F of the toilet bowl 300, but constitutes an inclined surface inclined from the vertical to the front, that is, within 45 degrees from the bowl 310, more preferably about 20 degrees. Yes.

The inclined front surface 510 is provided with an opening 520 for inserting and removing a cleaning nozzle for cleaning the “wet”. The opening 520 is provided with a closing plate 525, and the cleaning nozzle is accommodated on the back side of the closing plate 525.
Thus, the storage space of the cleaning nozzle can be expanded by inclining the front surface 510 toward the front, that is, toward the bowl 310.

9 and 10 are schematic cross-sectional views of the sanitary washing toilet seat device of the present specific example and the comparative example.
9A and 9B show a state in which the three-stage cleaning nozzle is housed in the sanitary washing toilet seat apparatus body 500 in the present invention and the comparative example, respectively. FIGS. 10A and 10B show a state in which the cleaning nozzle has advanced into the bowl 310 in the present invention and the comparative example, respectively.

The basic structure of the cleaning nozzle 530 can be similar to that described above with respect to FIG. Here, in the sanitary washing toilet seat apparatus body 500 of the comparative example, the front surface 510 facing the bowl 310 is formed perpendicular to the flat surface 300F of the toilet bowl 300. When this specific example and the sanitary washing toilet seat apparatus main body 500 of the comparative example are compared, as is clear from FIGS. 9A and 9B, when the depth D of the bottom surface of the main body 500 is the same, The storage size of the cleaning nozzle stored in the container is different. That is, according to this specific example, the storage size L1 can be made longer than the storage size L2 of the comparative example by inclining the front surface 510 forward. That is, according to the present specific example, the mounting base 532 and the first to third cylinders 534 to 538 can be lengthened, and at the same time, the slide amount can be increased.
As a result, according to this example, the cleaning nozzle can be advanced to a far position with a margin.

  That is, in the use state, as shown in FIGS. 10A and 10B, the first cylinder 534 moves forward on the mounting base 532, and the second cylinder 536 and the third cylinder 538 are moved forward. Each advances forward. At this time, according to this example, as illustrated in FIG. 10A, the stroke of the first cylinder 534 on the mounting base 532 has a margin S1, and the second cylinder relative to the first cylinder 534 There is also a margin S2 for the stroke of 536. Therefore, compared with the comparative example, according to the present invention, there is less “rattle” of the nozzle and “positional deviation” of the tip, and the nozzle can be advanced further. In addition, a “move cleaning function” that discharges water while swinging the cleaning nozzle back and forth can be reliably executed.

  On the other hand, according to the present specific example, the front surface 510 of the sanitary washing toilet seat device body 500 is inclined forward, so that the front surface 510 can be hidden from the line of sight when the male is used. Since the front surface 510 of the sanitary washing toilet seat main body 500 faces the bowl 310, the “water splash” or the like of the collected water or the washing water from the washing nozzle is likely to adhere, and the dirt may be conspicuous. In the state where the toilet seat 410 is lowered, as illustrated in FIG. 7, the front portion of the sanitary washing toilet seat apparatus body 500 is hidden under the toilet seat 410, but if the toilet seat 410 is raised during men's small use, sanitary washing is performed. The front surface 510 of the toilet seat body is exposed.

  Even in such a case, as illustrated in FIG. 11, according to the present specific example, the front surface 510 of the sanitary washing toilet seat apparatus body is inclined forward, thereby hiding dirt attached to the front surface 510 from the user's line of sight. be able to. As a result, a comfortable feeling can be obtained without causing discomfort. In cleaning, the front surface 510 can be easily wiped by bending or squatting near the toilet 300, and the cleaning property is also good.

FIG. 12 is a schematic perspective view illustrating a sanitary washing toilet seat device body 500 of the third specific example of the embodiment of the invention. In the figure, the toilet seat and the toilet lid are omitted for convenience.
In this specific example, among the front surface 510 facing the bowl 310 of the sanitary washing toilet seat apparatus main body 500, the center vicinity 510C is an inclined surface inclined forward, but in the vicinity of both ends 510E, the upper portion of the toilet bowl 300 is provided. The surface is substantially perpendicular to the flat surface 300F.

  In this way, the space for accommodating the cleaning nozzle is secured, and the opening of the bowl 310 on both the left and right sides (510E) is not narrowed, and the design feels excellent.

Next, a deodorizing apparatus that can be provided in the sanitary washing toilet seat apparatus of this embodiment will be described. FIG. 13 is a schematic diagram for explaining an example of a deodorizing apparatus.
1A is a plan view of the deodorizing apparatus, FIG. 1B is a front view of the deodorizing apparatus, and FIG. 1C is a side view of the deodorizing apparatus.

The deodorizing apparatus 550 of this specific example includes a slidable deodorizing nozzle 552, a main body portion 556 that accommodates the deodorizing nozzle, an exhaust fan 560 provided at the rear stage of the main body portion, and a catalyst provided at the exhaust port of the exhaust fan. Part 562. And the deodorizing nozzle 552 and the main-body part 556 are provided in the extension part 500P of the sanitary washing toilet seat apparatus main body 500. FIG.
The deodorizing nozzle 552 has a lid 553 provided at the tip and a filter 554 provided on the peripheral side surface. The filter 554 mainly has a role of removing dust and the like, and for example, a mesh-like filter having a mesh size of about 0.3 to 1.0 mesh can be used. The lid 553 is not provided with an opening for intake.

  In the use state of the deodorizing apparatus, as shown in FIG. 13A, the deodorizing nozzle 552 protrudes from the side toward the bowl 310 and sucks air in the bowl 310 through the filter 554 on the peripheral side surface. The air in the bowl 310 sucked from the filter 554 by the action of the exhaust fan 560 reaches the catalyst part 562 via the main body part 556 and the exhaust fan 560. The catalyst unit 562 removes odors by decomposing or adsorbing organic gas components contained in the intake air and causing odors, for example, by the action of oxygen or ozone. The exhaust gas from which the odor has been removed is discharged from an exhaust port provided on the back surface of the sanitary washing toilet seat apparatus body 500.

  On the other hand, the deodorizing nozzle 552 is housed in the sanitary washing toilet seat apparatus body 500 by sliding in the direction represented by the arrow A in FIG. At this time, the lid 553 forms a curved surface integrated with the curved front surface 510 of the sanitary washing toilet seat device body, and protects the inside of the sanitary washing toilet seat device body 500 and the deodorizing device 550 to prevent entry of small water and dirt. To do.

FIG. 14 is a schematic view illustrating the drive mechanism of the deodorizing nozzle 552.
That is, a motor 557 is provided in the main body 556 so that the ball screw 558 can be driven to rotate. On the other hand, the deodorizing nozzle 552 is provided with a bearing 555 that is screwed with the ball screw 558. When the motor 557 rotates the ball screw 558, a driving force in the sliding direction acts on the bearing 555 according to the rotation direction, and the deodorizing nozzle 552 slides in a predetermined direction. That is, the deodorizing nozzle 552 advances toward the bowl 310 from the side surface of the right extending portion 500P. In this way, the air in the bowl 310 can be efficiently sucked without interfering with the cleaning nozzle 530 that advances from the vicinity of the center of the curved front surface 510.

FIG. 15 is a flowchart illustrating the operation of the deodorizing apparatus 550 of this example.
That is, in the standby state, the deodorizing nozzle 552 slides in the direction of arrow A in FIG. 13A and is housed in the sanitary washing toilet seat apparatus body 500 (step S102). When the user sits on the toilet seat 410 of the toilet apparatus, the seating sensor 502 (see FIG. 1) provided in the sanitary washing toilet seat apparatus body 500 detects this (step S104).
Then, in response to a command from a control unit (not shown) built in the sanitary washing toilet seat apparatus main body 500, the deodorizing nozzle 552 moves forward and enters the state shown in FIG. 13A (step S106). Subsequently, the exhaust fan 560 starts a low speed operation (step S108). That is, the air in the bowl 310 is sucked by the exhaust fan 560, the odor is removed by the catalyst unit 562, and then discharged.

Next, when the user stands up from the toilet seat 410 of the toilet device, the seating sensor 502 is not detected (step S110).
Then, the exhaust fan 560 starts high speed operation (step S112). As a result, the odor in the bowl 310 immediately after the user stands up can be sucked into the deodorizing device without deviating upward and deodorized.

  When deodorization is performed by high-speed operation for a certain time (step S114), the exhaust fan 560 is stopped (step S116), and the deodorization nozzle 552 is slid in the direction of arrow A in FIG. (Step S118). In this way, the process returns to the standby state again (step S120).

  As described above, according to this specific example, the deodorizing nozzle 552 advances into the bowl 310 from the side of the curved front surface 510 in conjunction with the seating of the user, and the deodorizing operation can be started reliably and quickly. On the other hand, the deodorizing nozzle 552 is housed in the sanitary washing toilet seat main body 500 and protected by a lid 553 that forms a curved surface integrated with the curved front surface 510, for example, when used by men. is there. Accordingly, it is possible to realize a toilet apparatus that can prevent intrusion of small water and dirt and has a clean appearance and excellent usability.

Next, a warm air drying device that can be provided in the sanitary washing toilet seat device of the present embodiment will be described.
FIG. 16 is a schematic diagram for explaining an example of a warm air drying device.
1A is a side view of the hot air drying device, FIG. 1B is a plan view of the hot air drying device, and FIG. 1C is a front view of the hot air drying device.
The hot air drying device 570 includes a blower fan 572, a heater portion 574 provided on the discharge side thereof, and a blower passage 576 provided downstream thereof. The blower fan takes in air from the back side of the sanitary washing toilet seat apparatus body 500 and blows it to the heater unit 574. The air heated in the heater unit 574 is sent to the air blowing path 576. The air passage 576 is provided on both sides of the cleaning nozzle 530 in a branched manner. The hot air discharged from the air passages 576 is discharged toward the “butt” of the user through the opening 520 of the sanitary washing toilet seat apparatus body 500. In this way, it is possible to dry quickly by applying warm air to the wet “wet” after washing by the washing nozzle 530.

  At this time, the direction of the warm air can be adjusted by controlling the angle of the closing plate 525 provided in the opening 520. That is, as shown in FIG. 16A, when the cleaning nozzle 530 advances, the opening angle of the closing plate 525 is increased so as not to interfere with the nozzle, while when the warm air is sent, the closing plate 525 The opening angle can be reduced to adjust the direction of the warm air.

FIG. 17 is a schematic diagram for explaining the operation of the closing plate 525.
That is, in consideration of the size and arrangement of the blower fan 572 and the heater unit 574, even when the shape of the blower passage 576 is devised, it is not easy to discharge the warm air in the horizontal direction, and is represented by a broken line arrow W1 in FIG. As such, the warm air is discharged obliquely downward. However, in this case, the warm air is not efficiently applied to the “butt” of the user sitting on the toilet seat 410.

  On the other hand, by controlling the opening angle of the closing plate 525, as shown by the arrow W2 in FIG. 17, the hot air discharged from the air passage 576 can be guided in the direction of “wet”. In particular, in the present embodiment, as described above with reference to FIGS. 1 to 12, the front surface of the sanitary washing toilet seat apparatus body 500 does not cover the rear portion of the bowl 310, and is substantially continuous with the curved side wall surface of the opening of the bowl 310. It is set back backward (in a direction away from the bowl 310). Therefore, it is necessary to send warm air from a position far away from the comparative example illustrated in FIG. On the other hand, according to this specific example, by using the closing plate 525 as a “guide” for hot air and controlling the opening angle, the hot air can be reliably and easily applied to the “butt”. .

  Further, in this specific example, the direction of the warm air can be changed according to the opening angle of the closing plate 525, so that, for example, the user can adjust the opening angle of the closing plate 525 to meet the user's preference. You can direct the warm air in any direction. Furthermore, the direction of the hot air can be changed periodically by periodically changing the opening angle of the closing plate 525 so that the hot air can be uniformly applied to a wide range of the “buttock”.

FIG. 18 is a schematic view illustrating the opening / closing mechanism of the closing plate 525.
That is, in this specific example, a linear actuator 526 is provided and driven in the direction of arrow A. The closing plate 525 is urged in the opening direction by a spring (not shown) or the like. Then, by pushing the convex portion 525P provided on the back surface of the closing plate 525 with the convex portion 526P at the lower end of the linear actuator 526, the closing plate 525 can be closed or opened to a predetermined angle.

  For example, in the figure, when the linear actuator 526 is at the lowest position A1, the closing plate 525 is in a completely closed state P1. When the linear actuator 526 is raised to the position A2, the closing plate 525 is in a state P2 opened to an angle close to horizontal. For example, in this state, the warm air sent from the warm air drying device 570 can be guided toward the user's “buttock”. Further, when the linear actuator 526 is further raised to the position A3, the closing plate 525 is further opened P3. In this state, the cleaning nozzle 530 can advance without interference.

  Further, in this specific example, when the warm air is sent out, if the linear actuator 526 is moved up and down within a predetermined range, the opening angle of the closing plate 525 is periodically changed to have a wide range of “tails”. You can also apply hot air.

Note that the drive mechanism shown in FIG. 18 is merely an example, and various mechanisms can be used as the mechanism for opening and closing the closing plate 525. For example, the closing plate 525 may be opened and closed using the output of a motor for moving the cleaning nozzle 530 forward.
On the other hand, the opening angle of the closing plate 525 may be adjusted by the cleaning nozzle 530. That is, the closing plate 525 can be biased to a closed position by a spring or the like, and the closing plate 525 can be pushed and opened by the cleaning nozzle 530. In this case, the opening angle of the closing plate 525 can be adjusted by the advancement amount of the cleaning nozzle 530.

FIG. 19 is a flowchart illustrating an example of a cleaning / hot air drying operation sequence by the cleaning nozzle and the hot air drying device.
First, in the standby state, the cleaning nozzle 530 is in the housed state, and the closing plate 525 is closed (step S202).
When the user sits on the toilet seat 410 and operates the sanitary washing toilet seat apparatus body 500 or the remote controller to turn on the water discharge switch (step S204), the closing plate 525 first opens to the water discharge position (FIG. 18: P3) (step S204). S206). At this time, the operation of the washing nozzle may be permitted only when the seating sensor 502 (see FIG. 1) provided in the sanitary washing toilet seat apparatus body 500 is in the detection state.

  When the closing plate 525 is opened, the cleaning nozzle 530 is advanced to start water discharge (step S208). When the user turns off the water discharge switch (step S210), the water discharge stops, the cleaning nozzle 530 is stored (step S212), and the closing plate 525 is closed (step S214).

Next, when the user turns on the hot air switch (step S216), the closing plate 525 opens to the hot air position (FIG. 18: P2). Then, the heater unit 574 and the blower fan 572 are energized (step S218), and warm air is discharged toward the user's “buttock” and the like.
When the user turns off the hot air switch (step S220), energization of the heater unit 574 and the blower fan 572 is terminated (step S222), the closing plate 525 is closed (step S224), and the standby state is restored (step S224). Step S226).

Next, the drainage channel of “waste water” that can be provided in the toilet apparatus of the present embodiment will be described.
FIG. 20 is a perspective view illustrating a sanitary washing toilet seat apparatus body 500 provided with a drainage channel for waste water.
FIG. 21 is a cross-sectional view of the sanitary washing toilet seat apparatus main body 500.

  That is, in the sanitary washing toilet seat main body 500, a water channel system for supplying hot water or water to the washing nozzle 530 is incorporated. In this water channel system, it may be necessary to discharge water or hot water as “waste water” out of the channel. Examples of sources of “waste water” include the following elements.

First, a “drain valve” provided in a heat exchange tank for heating water can be mentioned. This is a valve for draining water from the heat exchange tank during maintenance or the like. Next, a “safety valve” provided on the secondary side of the pressure regulating valve on the water channel can be cited. This is a valve for discharging water out of the system when the pressure regulating valve breaks down and the secondary pressure in the water channel increases. Moreover, a “vacuum breaker” can be mentioned. This is an element that is attached to the heat exchange tank and discharges the backflow water out of the system when the water flows backward from the direction of the washing nozzle.
In this specific example, drainage tubes 592 are connected to these elements, and “waste water” can be drained from the opening 520.

  When warm water is discharged from the cleaning nozzle 530, the cold water in the water channel may be discharged by discharging water from the water outlet in the sanitary washing toilet seat apparatus body 500 in advance. In addition, when the cleaning by the cleaning nozzle 530 is completed, water is discharged from the water outlet in the sanitary washing toilet seat apparatus body 500, thereby preventing adhesion of foreign matters around the water outlet. Furthermore, before using the cleaning nozzle 530, the cleaning nozzle 530 may be cleaned by discharging water from the water outlet. When such nozzle cleaning processing is performed in the sanitary cleaning toilet seat apparatus main body 500, as shown in FIG. 17, water is discharged from the cleaning nozzle 530 with the tip of the cleaning nozzle 530 inserted into the nozzle cleaning chamber 540. Let Then, the vicinity of the tip of the cleaning nozzle 530 is cleaned. However, it is necessary to discharge this washing water out of the sanitary washing toilet seat main body 500.

  In this specific example, a drainage channel 590 for “waste water” is provided for these cases. The drainage channel 590 communicates with the inside of the sanitary washing toilet seat device body 500 and is formed to extend vertically downward from the front surface 510. Further, in this specific example, “waste water” that is connected to the opening 520 provided on the front surface 510 of the sanitary washing toilet seat apparatus body 500 and is discharged through the opening 520 is guided into the bowl 310 of the sitting toilet. Have a role. By providing such a drainage channel 590, it is possible to prevent “waste water” from remaining in the sanitary washing toilet seat device body 500, and when the “waste water” is discharged, the sanitary washing toilet seat device body 500. And intrusion into the gap between the stool and the seat 300.

  Furthermore, by providing the drainage channel 590 extending downward in this manner, the effect of facilitating “positioning” when the sanitary washing toilet seat apparatus body 500 is attached to the seating toilet 300 is also obtained. That is, the sanitary washing toilet seat device main body 500 is placed on the sitting toilet 300 and pushed backward (in a direction away from the bowl 310), and the position where the drainage channel 590 is in contact with the side wall surface of the bowl 310 is determined. It can be an attachment position. In this state, the front surface 510 of the sanitary washing toilet seat device body 500 is substantially flush with the side wall surface of the opening of the bowl 310. That is, the sanitary washing toilet seat apparatus body 500 can be easily positioned at an ideal position by bringing the drainage channel 590 into contact with the side wall surface of the bowl 310.
