Description

  The present invention relates to a sanitary washing device and a toilet device, and more specifically to a sanitary washing 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.

As for the sanitary washing apparatus, the thing of the form which accommodates the washing nozzle which injects washing water in the inside so that advancement / retraction is possible, and installs and uses it in the upper surface rear part of a seat toilet has become the mainstream. Then, for the purpose of improving the cleanability of such a sanitary washing device, the miniaturization thereof is being studied. That is, if the front surface of the sanitary washing device is retracted, the portion of the sitting toilet bowl covered on the bowl can be reduced, and the trouble of removing the dirt on the back surface of the sanitary washing device placed on the bowl can be saved. For this purpose, for example, it is conceivable to recede the front surface of the sanitary washing device to form a curved shape along the opening of the bowl of the toilet bowl (Patent Document 1).
JP 2003-339578 A

  However, a new problem arises when the front of the sanitary washing device is retracted. In other words, since the hot air outlet for drying the user's “wet” or the like is moved further backward than before, the warm air is diffused at the air outlet having a flat opening like the conventional one. As a result, the hot air cannot reach the “buttock” efficiently.

  According to the present invention, it is possible to provide a sanitary washing apparatus and a toilet apparatus equipped with the sanitary washing apparatus that can efficiently apply hot air to a “butt” while reducing the portion of the sanitary washing apparatus that covers the bowl of the toilet bowl. it can.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic perspective view showing the appearance of a toilet apparatus according to an embodiment of the present invention.
Moreover, FIG. 2 represents the state which opened the toilet seat 200 and the toilet lid 300 of this toilet apparatus.

  The toilet apparatus of the present embodiment includes a Western-style sitting toilet 800 and a sanitary washing device 100 provided thereon. The sanitary washing device 100 includes a main body 400, a toilet seat 200, and a toilet lid 300. The toilet seat 200 and the toilet lid 300 are pivotally supported by the main body 400 so as to be freely opened and closed.

  The main body 400 incorporates a sanitary washing function unit for realizing sanitary washing. That is, the seating sensor 420 detects that the user is sitting on the toilet seat 200, and a water discharge nozzle (not shown) is advanced from the main body 400 into the bowl of the toilet bowl 800 according to the user's switch operation or the like. By spraying water from a spout provided near the tip, it is possible to wash the “buttock” of the user sitting on the toilet seat. In the present specification, “water” includes not only cold water but also heated hot water.

  In addition to the “warm air drying unit”, the main body 400 is appropriately provided with various mechanisms such as a “deodorizing unit” and an “indoor heating unit”, and an exhaust port 440 and an exhaust port 450 are provided on the side surfaces thereof. It is provided as appropriate. It is also possible to provide an “automatic opening / closing function” that automatically opens the toilet lid 300 upon detection of the approach of the user and automatically closes the toilet lid 300 when the user disappears. Further, an “automatic water washing function” for flowing the washing water to the toilet bowl 800 may be added to the sanitary washing device 100. This is a function of providing a drive mechanism for operating a drainage mechanism of a low tank or a flush valve, outputting a signal for operating this drive mechanism from the main body 400, and automatically flowing flush water to the toilet bowl 800.

  These functions can be executed and set by appropriately operating an operation unit (not shown) provided in the main body 400, and a remote control (not shown) installed on the wall surface of the toilet is operated. Can also be executed. Further, in the case of the specific example shown in FIG. 1, a recessed portion 410 is formed on the upper surface of the main body portion 400, and the human body detection sensor 500 is provided so as to be partially embedded in the recessed portion 410. When the toilet lid 300 is closed, the human body detection sensor 500 detects the presence of the user through the transmission window 310 provided in the vicinity of the base.

  And in this embodiment, as represented to FIG. 2, the main-body part 400 has the shape which retracted according to opening of the bowl 810 of the toilet bowl 800. FIG. That is, the main body 400 is installed at the upper rear side of the toilet bowl 800, and its front surface slightly protrudes toward the bowl 810 side from the opening end of the bowl 810 along the shape of the opening of the bowl 810 of the toilet bowl 800. The curved concave surface 402 is curved in a concave shape. And the extension part 404 extended toward the front along the opening of the bowl 810 is provided in the right and left of the curved concave surface 402. In addition, an inclined surface 408 that increases toward the rear is provided above the curved concave surface 402 and the extending portion 404. Here, “rear” means a side where a low tank, a flush valve, etc. are usually installed as shown in FIG. 1, and means a side far from the user in a normal use mode.

FIG. 3 is a schematic view of the main body 400 viewed from the front.
The width of the curved concave surface 402 in the height direction is large near the center and gradually decreases as the left and right extending portions 404 are approached. That is, the curved concave surface 402, which is a substantially vertical surface, has a shape that is high near the center and gradually decreases as the left and right extending portions 404 are approached. More specifically, the center of the curved concave surface 402 is about 45 mm, and the left and right ends are about 13 mm in height, and the ratio is about 7: 2.
In this way, by raising the vicinity of the center of the curved concave surface 402, even if a small amount of water is applied to the main body 400 when the male standing position is used, small Can be dropped into the bowl 810. That is, it is possible to suppress the small water from being applied to the inclined surface 408 of the main body 400, and the contamination due to the small water can be reduced as much as possible. On the other hand, by reducing the height of the left and right end portions of the curved concave surface 402, the seat surface of the toilet seat 200 covering the curved concave surface 402 can be lowered to a low seating level.

On the other hand, two openings are provided adjacent to the high portion near the center of the curved concave surface 402 at a position where one end of the discharge nozzle of the water discharge nozzle and the hot air drying unit faces. In the center of the curved concave surface 402, an opening for advancing and retreating the water discharge nozzle and a nozzle damper 460 as a closing member for covering the opening are provided, and on the right side thereof, an opening facing the air outlet of the hot air duct and A warm air damper 470 is provided as a closing member that covers the opening. These are all supported so as to be openable and closable, and are all closed in the standby state. Then, when the water discharge nozzle advances to wash the “butt” of the user sitting on the toilet seat 200, the nozzle damper 460 is pushed by the water discharge nozzle or electrically operated. Further, when the hot air is blown from the hot air drying unit 620 toward the user's “tail” or the like, the hot air damper 470 is opened by the hot air or by electric power.
Instead of the two openings and the dampers 460 and 470 that cover the openings, a single opening and a damper that are commonly used for the advance and retreat of the water discharge nozzle and the blowing of warm air may be provided. You may make it cover a part with one damper.

Thus, by providing the nozzle damper 460 at a high portion near the center of the curved concave surface 402, for example, a multistage water discharge nozzle having a large diameter can be advanced from the curved concave surface 402 into the bowl 810. That is, since the curved concave surface 402 is formed by retreating the front surface of the main body 400, the advance distance of the water discharge nozzle built in the main body 400 must be increased. For this reason, the water discharge nozzle needs to have a two-stage structure in which the nozzle head and one cylinder portion are slidable, or a multistage structure having more than that.
FIG. 4 is a schematic view illustrating a nozzle unit that can be provided in the sanitary washing device 100 of this embodiment.
The nozzle unit 610 has a three-stage structure. In other words, the third cylinder portion 612 is fixed on the nozzle base portion 611, the second cylinder portion 613 is supported so as to be able to advance and retreat, and the first cylinder portion 614 is located inside the second cylinder portion 613. A nozzle head 615 having an injection hole 616 inside the first cylinder portion 614 is supported so as to be able to advance and retract. In addition, a nozzle cleaning chamber 617 for cleaning the body of the water discharge nozzle is provided in front of the third cylinder portion 612. The water discharge nozzle is housed in the main body 400 in the retracted state as shown in FIG. 4A, and in the advanced state as shown in FIG. 4B, the nozzle damper 460 ( Open (see FIG. 3) and advance into the bowl 810.

  Such a water discharge nozzle inevitably has a large diameter in order to have a multistage structure. For this reason, in order to advance from the main body 400, the nozzle damper 460 must also be enlarged. On the other hand, according to the present embodiment, the central portion of the curved concave surface 402 is made high, and the nozzle damper 460 is provided at this high portion, whereby a multistage having a large diameter and a long advance distance as illustrated in FIG. The water discharge nozzle of the type can be advanced into the bowl 810 to reliably discharge water toward the user's “buttock” or the like.

Furthermore, according to the present embodiment, by providing the hot air damper 470 at a high portion near the center of the curved concave surface 402, the hot air outlet for drying the user's “buttock” or the like can be formed into a suitable shape. .
FIG. 5 is a schematic view illustrating the shape of the hot air outlet. That is, FIG. 5A illustrates the air outlet in the present embodiment, and FIG. 5B illustrates the air outlet of the comparative example.

  In order to blow out the warm air of a predetermined air volume, the opening area of the air outlet needs to be a predetermined size. When the height of the front surface of the main body 400 is low, as shown in FIG. 5B, it is unavoidable to employ a blower outlet having a small width in the vertical direction and flat in the horizontal direction. For example, in the case of the blowout port of the comparative example illustrated in FIG. 5B, the width A in the vertical direction is 10 mm, whereas the width B is 43 mm, and the opening is flat in the horizontal direction.

  However, as described above with reference to FIGS. 2 and 3, the front surface of the main body 400 is retreated to form the curved concave surface 402, so that the position of the air outlet is moved away from the “butt” of the user. In such a case, if a flat air outlet as shown in FIG. 5B is used, the hot air diffuses in the left-right direction, and a sufficient amount of hot air reaches the user's “buttock”. It becomes difficult.

  On the other hand, according to the present embodiment, as shown in FIG. 5A, it is possible to provide a blower outlet having a vertical width and a horizontal width that are close to each other. This is because the vicinity of the center of the curved concave surface 402 is raised, and the nozzle damper 460 is provided at this high portion. For example, in the case of the air outlet illustrated in FIG. 5A, the vertical width A of the opening can be expanded to 18 millimeters. As a result, the width B in the horizontal direction can be reduced to 27 millimeters, and the aspect ratio of the opening dimension can be made close to 1. In this way, by bringing the aspect ratio of the opening dimensions close to 1, the focused hot air can be blown out. As a result, the hot air focused on the user's “butt” can be made to reach from the curved concave surface 402 that has been moved backward as viewed from the user ’s “butt”.

In addition, the opening area of the blower outlet of the comparative example shown in FIG. 5B is about 430 square millimeters, whereas the opening area of the blower outlet shown in FIG. 5A is about 480 millimeters. In other words, by providing the nozzle damper 460 in the tall portion near the center of the curved concave surface 402, the vertical dimension of the blowout port can be increased, and the opening area can be enlarged while the aspect ratio of the opening is close to 1. It becomes.
The effect of converging warm air in this embodiment will be described in detail later with reference to a specific example.

Next, the effect of making the curved concave surface 402 by retracting the front surface of the main body 400 backward will be described.
FIG. 6 is a perspective view of the toilet device according to the present embodiment as viewed from the front with the toilet seat 200 and the toilet lid 300 removed.
Moreover, FIG. 7 is the perspective view which looked at the toilet apparatus of the comparative example from the front. 6 and 7 show a view of the bowl 810 from the viewpoint of the user who cleans the toilet while squatting in front of the toilet 800, specifically, approximately 100 millimeters away from the front end of the toilet 800, It represents the appearance of the bowl 810 viewed from a height of about 1000 millimeters from the floor.

Moreover, FIG. 8 is sectional drawing of the toilet apparatus of this embodiment,
FIG. 9 is a cross-sectional view of the toilet device of the first comparative example. FIGS. 8 and 9 are schematic diagrams for explaining a range that can be seen from the user's eyes when the toilet is cleaned in a state of squatting in front of the toilet 800. FIG.

  First, a comparative example will be described. In the first comparative example shown in FIGS. 7 and 9, the main body 400 extends above the bowl 810 of the toilet bowl 800, and a region 400 </ b> P indicated by a broken line is behind the opening of the bowl 810. The part is blocked. However, when the main body 400 protrudes above the bowl 810 in this way, small water tends to be applied to the main body 400 when the male is standing up. Further, when the main body 400 protrudes above the bowl 810 in this way, the effective opening area of the bowl 810 is narrowed, so that a stenosis sensation is given to a man who uses it in a standing position. In addition, dirt easily adheres to the back side of the protruding area 400P as described above, and there is room for improvement in terms of cleanability.

Furthermore, when the main body 400 protrudes above the bowl 810 as described above, even if dirt is attached to the rear upper part of the bowl 810, it is difficult to clean the portion. That is, in the comparative example shown in FIG. 7, even when the user squats in front of the toilet bowl 800, the rim portion 820 at the upper end of the bowl 810 is hidden behind the protruding region 400P of the main body portion and cannot be seen. For this reason, in order for the user to clean the rim portion 820 below the region 400P, the user has to look into it in a bent posture.
On the other hand, in this embodiment, as shown in FIGS. 6 and 8, the curved surface 402 is formed by retreating the front surface of the main body 400, so that it can be used in a male standing position. In addition, it is difficult for small water to be applied, and the user is not given a visual stenosis. Further, as described above with reference to FIG. 3, by raising the vicinity of the center of the curved concave surface 402, even if a small amount of water is applied to the main body 400 when the male standing position is used, the back of the curved concave surface 402 near the center. The small portion can receive small water and drop it into the bowl 810. That is, it is possible to suppress the small water from being applied to the inclined surface 408 of the main body 400, and the contamination due to the small water can be reduced as much as possible.

  And by retreating the main body part 400 in this way, it is possible to suppress the adhesion of dirt to the back surface of the main body part 400, and the cleanability can be remarkably improved. That is, according to the present embodiment, as shown in FIG. 8, it can be seen up to the vicinity of the upper end of the rim portion 820 at the rear end of the bowl 810 as seen from the line of sight of the user squatting in front of the toilet bowl 800. Therefore, the user can clean and cleanly clean the back end of the bowl 810 using a rag or a brush in the posture, and confirm that the dirt has been removed and has been cleaned. Further, in the present embodiment, since the amount of protrusion of the main body 400 on the bowl 810 is suppressed, it is easy to clean dirt and the like attached to the back side of the protrusion. For example, even when cleaning with a rag or the like, the user can quickly wipe away from side to side with the rag applied to the back side of the main body 400.

FIG. 10 is a schematic plan view for explaining the relationship between the curved concave surface 402 and the bowl 810 in the present embodiment.
As shown in the figure, the curved concave surface 402 of the main body portion maintains a form substantially conforming to the opening shape of the bowl 810, and almost the entire curved concave surface 402 is slightly closer to the bowl 810 side than the opening end of the bowl 810. Protruding. When the protruding amounts to the bowl 810 at the left and right front ends of the curved concave surface 402 are a and b, and the protruding amount to the bowl 810 near the center is c, a and b are relatively small, and c is relatively large. can do. In this way, it is possible to effectively prevent entry of small water or the like into the gap between the main body 400 and the opening end of the bowl 810 while exposing most of the bowl 810 substantially continuously with the opening shape of the bowl 810. . This is because the small water is mainly directed to the vicinity of the center when the male is standing up, and the gap between the main body 400 and the open end of the bowl 810 is covered with the curved concave surface 402. This is because small water is not directly applied to the gap. Moreover, if it does in this way, it will also become easy to ensure the space (protrusion part) for drainage and deodorizing.

  Specifically, for example, a and b can be about several millimeters to about 10 millimeters, and c can be about 10 millimeters to about 10 millimeters. If the curved concave surface 402 is slightly protruded in this way, the entry of small water can be suppressed as much as possible. Furthermore, drainage from the main body 400 to the bowl 810 can be secured, and a deodorizing air inlet for a deodorizing function can be secured.

  In addition, by restricting the amount of protrusion of the main body 400 to the bowl 810 in this way, the dust cloth is evenly applied to the back side of the main body 400 in the range from the tip of the user's finger to the first joint, for example. It is also possible. That is, the user applies a dust cloth to the tip of the finger while keeping the first joint of the finger lightly bent, and slides the dust cloth to the left and right along the curved concave surface 402 of the main body section 400, whereby the main body section 400. It is possible to reliably clean the back side of the rim and the upper end portion of the rim portion 820 adjacent thereto. Since the curved concave surface 402 forms a curved surface that is substantially continuous with the bowl 810, it can be cleaned smoothly and reliably without any rags being caught.

Next, an example of the internal structure of the sanitary washing device of this embodiment will be described.
FIG. 11 is a perspective view of the inside of the main body 400 viewed from the front.
The main body 400 includes a case cover 430 and a case plate 770 that constitute a housing. A human body detection sensor 500 and a display unit 670 are appropriately provided on the upper surface of the case cover 430. The display unit 670 has a role of appropriately displaying, for example, the power-on state of the toilet device. In addition, an electric opening / closing unit 780 for automatically opening and closing the toilet seat 200 is provided on the upper portion of the front portion of the case cover 430 so as to protrude.

  On the other hand, when the inside of the case cover 430 is viewed, a nozzle unit 610, a hot air drying unit 620, and a deodorizing unit 630 are provided in front of the case cover 430. As described above with reference to FIG. 4, the nozzle unit 610 has a water discharge nozzle that can freely move back and forth, and has a role of cleaning by spraying water on a “butt” of a user sitting on the toilet seat 200. The hot air drying unit 620 has an air outlet as described above with reference to FIG. 5, and has a role of applying hot air to a user's “buttock” sitting on the toilet seat 200 and drying it. The deodorizing unit 630 has a role of sucking air in the bowl 810 of the toilet bowl 800, deodorizing it, and discharging it from the exhaust port 440.

  Further, an AC (alternating current) controller 640 is provided above the front part inside the case cover 430, and a pump unit 650 and a heat exchange unit 660 are provided at the rear part thereof. The water supplied to the heat exchange unit 660 is heated, the pump unit 650 imparts pulsation to the water, and the pulsating water is supplied to the nozzle unit 610.

  Further, an auxiliary operation unit (not shown) is appropriately provided on the side surface of the case cover 430. The auxiliary operation unit is provided with a switch for operating cleaning of the “wet” by the nozzle unit 610. For example, the operation of the sanitary cleaning function can be controlled even when operation by a remote controller (not shown) is impossible. Is.

  On the other hand, an electric opening / closing unit 720 and a toilet flushing valve unit 730 are provided at the rear of the case cover 430. The electric opening / closing unit 720 has a role of opening and closing the toilet lid 300. The toilet flushing valve unit 730 has a role of controlling the supply of flush water that flows to the toilet 800. That is, the toilet device of this specific example has a so-called “water supply directly connected water supply” structure, and supplies water supplied from the water supply to the toilet bowl 800 via the toilet flush valve unit 730 without providing a low tank or the like. Perform cleaning. However, this invention is not limited to this, The sanitary washing apparatus which can be attached to a low tank type toilet is also included.

  On the other hand, an indoor heating unit 740 is provided at the rearmost part of the case cover 430. The indoor heating unit 740 has a role of heating the toilet space in which the toilet apparatus is installed by discharging warm air from the discharge port 450 (see FIG. 1).

  And drainage may arise in the inside of main part 400 provided with such various mechanisms. For example, the nozzle unit 610 includes a nozzle cleaning chamber at the tip thereof, and cleans the water discharge nozzle by spraying water in the nozzle cleaning chamber before and after using the water discharge nozzle. This washing water is discharged to the bowl 810 from a toy-shaped drainage portion 771 provided at the center of the front end of the case plate 770.

  The valve unit that supplies water to the heat exchange unit 660 is provided with a vacuum breaker and a safety valve (not shown). The vacuum breaker is a valve for draining water remaining in the piping inside the sanitary washing device 100, for example, when the sanitary washing device 100 is removed from the water supply pipe. The safety valve is a valve that discharges water when the water pressure of the drainage system rises above a predetermined value.

  When the width of the sanitary washing device 100 is large and protrudes in the lateral direction from the toilet bowl 800, water discharged from the vacuum breaker or the safety valve can be drained to the outside from the protruding portion. However, as illustrated in FIG. 1 and FIG. 6, if the width of the sanitary washing device 100 is reduced to the same level as the width of the toilet bowl 800, drainage from the vacuum breaker and the safety valve is taken out from the side of the sanitary washing device 100. It becomes difficult.

On the other hand, in this specific example, the water discharged from the vacuum breaker or the safety valve can be drained into the bowl 810.
FIG. 12 is a schematic diagram showing a state in which the upper case and the internal mechanism of the main body 400 are removed and the case plate (mounting substrate) 770 is exposed.
The drainage hole 773 is provided in a portion protruding from the opening end of the bowl 810 toward the bowl 810 side, and the drainage from the vacuum breaker or the safety valve can be discharged to the bowl 810 by connecting to the vacuum breaker or the safety valve with a drainage tube. Further, by providing a toy-shaped drainage portion 771 at the center end portion of the case plate 770 that protrudes toward the bowl 810 from the opening end of the bowl 810, the water discharge nozzle from the nozzle cleaning chamber 617 (see FIG. 4). Drainage can also be discharged to the bowl 810. Furthermore, an intake hole 774 for deodorization can be provided in a portion protruding toward the bowl 810 from the opening end of the bowl 810.

  In this way, the main body 400 slightly protrudes toward the bowl 810 from the opening end of the bowl 810, whereby the waste water from the vacuum breaker, the safety valve, and the water discharge nozzle can be discharged to the bowl 810. Furthermore, an intake hole 774 for deodorization can be provided to secure an opening area for obtaining an air volume required for deodorization.

Furthermore, according to the present embodiment, the vicinity of the center of the curved concave surface 402 is raised, and the drain hole 773 is provided on the lower surface at a position closer to the center than the left and right ends of the curved concave surface. It becomes easy to connect the drainage tube.
FIG. 13 is a schematic view illustrating a cross-sectional structure of a connection portion of a drain tube from a vacuum breaker or a safety valve. As shown in FIG. 13A, when the drainage hole 773 is provided below the portion where the curved concave surface 402 is low, the drainage tube 662 is crushed by hitting the case cover 430 as shown by the broken line. There is a risk that it will not drain well. On the other hand, as shown in FIG. 13B, when the drainage hole 773 is provided under the portion where the curved concave surface 402 is high, the case cover 430 and the drainage tube 662 Therefore, the drainage tube 662 can be surely drained without being crushed.

Next, the warm air drying unit provided in the present embodiment will be described in more detail with reference to specific examples.
FIG. 14 is a plan view of the hot air drying unit 620 mounted on the case plate.
That is, the hot air drying unit 620 includes an exhaust fan 622 incorporating a motor and a duct 624 incorporating a heater and a temperature sensor. The wind sent from the exhaust fan 622 is warmed in the duct 624 and discharged from the air outlet 626. In the present embodiment, as described above with reference to FIG. 5, the air outlet 626 is provided in a tall portion near the center of the curved concave surface 402 adjacent to the water discharge nozzle.

FIG. 15 is a schematic diagram showing the direction of the warm air discharged from the air outlet 626.
In the present embodiment, as shown in FIGS. 15A to 15C, the air outlet 626 provided behind the hot air damper 470 (see FIG. 3) provided near the center of the curved concave surface 402. The hot air H focused in the direction of the “butt” of the user sitting on the toilet seat 200 can be blown out. Since the air outlet 626 is not flat in the left-right (horizontal) direction and the aspect ratio of the opening dimension is close to 1, the discharged hot air H does not spread in the left-right (horizontal) direction, and the converged hot air H is far away. Can be delivered. Further, by increasing the vertical dimension of the air outlet 626, the hot air H can be directed upward. As a result, the warm air H having a sufficient air volume can be delivered to the “buttock” of the user sitting on the toilet seat 200.

16 to 18 are schematic diagrams showing the results of experiments conducted by the present inventors.

Thus, by raising the center of the hot air H, the hot air H can be reliably applied to the “butt” of the user.

  Further, as shown in FIG. 17B, in the comparative example, while the warm air H spreads in the left-right (horizontal) direction in the comparative example, as shown in FIG. The hot air H does not spread in the left-right direction, and the hot air H that has been focused can be delivered to the position of the user's “butt”.

  As a result, in the present specific example shown in FIG. 18A than the comparative example shown in FIG. Surely. That is, according to the present embodiment, as described above with reference to FIG. 5, by raising the vicinity of the center of the curved concave surface 402 and providing the warm air damper 470 at this high portion, the vertical direction of the warm air outlet 626 is increased. By expanding the dimensions and bringing the aspect ratio close to 1, the hot air H can be delivered far.
