Technical field

TECHNICAL FIELD [0001] The present invention relates to a sanitary washing device and a toilet device, and more specifically, a sanitary washing device and a sanitary washing device for washing a user's “butt” or the like seated on a Western-style sitting toilet with water. It is related with the toilet apparatus provided with the same sanitary washing function part.

Background art

[0002] The sanitary washing apparatus is mainly used in a form in which a water discharge nozzle for injecting washing water is accommodated therein so as to be able to advance and retreat, and is installed on an upper part of a sitting toilet. In addition, if such a sanitary washing device is equipped with a “warm air drying function” that blows hot air to dry the user ’s “wet” etc., it will be even easier to use and reduce the amount of toilet paper used. It is also effective for resource saving.

[0003] For example, an automatic local cleaning device is disclosed in which an opening through which a water discharge nozzle advances and retreats and an opening through which hot air is blown from a hot air duct are adjacent to each other, and each of these openings is covered with a lid that can be opened and closed. (Patent Document 1).

[0004] On the other hand, for the purpose of improving the cleanability of such a sanitary washing device, the miniaturization thereof is being studied. In other words, if the front surface of the sanitary washing device is retracted, the portion of the toilet bowl that covers the bowl can be reduced, and the trouble of removing the dirt on the back surface of the sanitary washing device that is placed on the bowl can be saved. For this purpose, for example, the front surface of the sanitary washing device may be formed in a curved shape so as to coincide with the open end of the bowl of the toilet bowl (Patent Document 2).

Problems to be solved by the invention

However, if the front surface of the sanitary washing device is aligned with the open end of the bowl, a gap between the sanitary washing device and the open end of the toilet bowl is exposed to the front surface. As a result, small water or the like easily enters this gap. This exposed gap, especially for small men standing In some cases, small water is directly applied to the water, and the small water may enter the gap and cause ammonia odor.

[0006] Further, when the front surface of the sanitary washing device is retracted, a new problem arises. In other words, since the hot air outlet for drying the user's “wet” and the like is forced to move backward more than before, hot air is blown out at the flat opening of the conventional opening. It spreads and the hot air cannot reach the “buttock” efficiently.

It may cause life.

[0007] Further, when the front surface of the sanitary washing device is curved along the opening end of the bowl and provided with an opening / closing lid for the water discharge nozzle and an opening / closing lid for hot air drying, the opening and closing lids are simultaneously opened. Collisions may cause malfunctions and failures.

[0008] Further, if the main body for realizing the sanitary washing function does not protrude at all in the toilet bowl opening, that is, the bowl, a suction port for deodorization cannot be provided. In addition, it becomes difficult to drain the waste water discharged from the main body into the bowl.

BEST MODE FOR CARRYING OUT THE INVENTION

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

FIG. 1 and FIG. 2 are schematic perspective views showing the appearance of a toilet apparatus according to an embodiment of the present invention.

FIG. 3 shows a state in which the toilet seat 200 and the toilet lid 300 of the toilet device are opened.

[0018] The toilet apparatus of the present embodiment includes a Western-style seat 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 with respect to the main body 400 so as to be freely opened and closed.

[0019] 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. By spraying water from the water outlet provided near the tip, it is possible to wash the “tail” of the user sitting on the toilet seat. In the present specification, the term “water” includes not only cold water but also heated hot water.

[0020] In addition, the main body 400 is appropriately provided with various mechanisms such as a "deodorizing unit", a "warm air drying unit", and an "indoor heating unit". And an outlet 450 from the room heating unit is provided as appropriate. It is also possible to provide an “automatic opening / closing function” that automatically opens the toilet lid 300 upon detecting the proximity of the user and automatically closes the toilet lid 300 when the user is removed! Furthermore, an “automatic water washing function” that allows flush water to flow through the toilet bowl 800 may be added to the sanitary washing device 100. This is a function of providing a drive mechanism for operating the drain mechanism of the low tank flush valve, outputting a signal for operating this drive mechanism from the main body 400, and automatically flowing the wash water to the toilet bowl 800.

[0021] These functions can be executed 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 or the like can be set. It can also be executed by manipulating it. In addition, a recessed portion 410 is formed on the upper surface of the main body 400, and the human body detection sensor 500 is provided so that a part of the recessed portion 410 is embedded. It is 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 near the base.

In the present embodiment, as shown in FIG. 3, the main body 400 has a shape retreated in accordance with the opening end of the bowl 810 of the toilet bowl 800. That is, the main body 400 is installed at the upper rear side of the toilet 800, and its front surface slightly protrudes toward the bowl 810 from the open end of the bowl 810 along the shape of the open end of the bowl 810 of the toilet 800. Thus, the curved concave surface 402 is curved in a concave shape.

[0023] On the left and right sides of the curved concave surface 402, extending portions 404 extending forward along the opening of the bowl 810 are provided. Also, above the curved concave surface 402 and the extension 404,

An inclined surface 408 is provided which increases toward the rear.

Here, “rear”, as shown in FIG. 1, is a side where a low tank or a flush valve is usually installed, and means a side far from the user's power in a normal use mode.

[0024] On the left and right sides of the curved concave surface 402, extending portions 404 are provided that extend forward along the opening end of the bowl 810. The curved concave surface 402 has a shape that gradually decreases as it approaches the left and right extending portions 404 that are higher in the center.

[0025] In the high portion near the center of the curved concave surface 402, there is provided an opening for advancing and retreating the water discharge nozzle and a nozzle damper 460 as a closing member for covering the opening, and on the right side is a hot air outlet. A hot air damper 470 is provided as a closing member that covers the hot air outlet. All of these are supported to be openable and closable, and in the standby state, all are closed. The nozzle damper 460 opens when the water discharge nozzle advances in order to wash the “buttock” of the user sitting on the toilet seat 200. Further, when the hot air is blown from the hot air drying unit 620 toward the user's “buttock”, the hot air damper 470 is opened.

[0026] According to the present embodiment, the curved concave surface 402 is slightly protruded toward the bowl 810 from the opening end of the bowl 810, so that the portion of the main body 400 that covers the bowl 810 is reduced. It is possible to effectively prevent small water or the like from entering the gap between the main body 400 and the open end of the bowl 810 while exposing most of the water. FIG. 4 is a schematic plan view showing the relationship between the bowl 810 and the curved concave surface 402. That is, almost the entire force of the curved concave surface 402 protrudes slightly toward the bowl side from the open end of the bowl 810. In this way, the gap between the main body 400 and the open end of the bowl 810 can be hidden. As a result, it is possible to prevent small water or the like from being directly applied to the gap between the main body 400 and the open end of the bowl 810, and effectively suppress the entry of small water or the like. This point will be described in detail later.

Hereinafter, the effect of using the curved concave surface 402 as the front surface of the main body 400 will be described first.

FIG. 5 is a perspective view in which the toilet seat 200 and the toilet lid 300 are removed from the toilet apparatus cover according to the present embodiment, and the toilet apparatus is viewed obliquely upward.

FIG. 6 is a perspective view of the toilet device of the first comparative example as viewed from the same angular force as FIG.

[0028] FIG. 7 is a perspective view of the toilet device force of the present embodiment when the toilet seat 200 and the toilet lid 300 are removed and the toilet device is viewed obliquely forward.

FIG. 8 is a perspective view of the toilet device of the first comparative example as viewed from the same angular force as FIG.

7 and 8 show a view of the bowl 810 from the viewpoint of the user who cleans the toilet bowl while squatting in front of the toilet bowl 800, and more specifically, about 10 from the front end of the toilet bowl 800. It shows the appearance of Bowl 810 when viewed from a height of about 1000 millimeters with a floor force of 0 millimeters.

FIG. 9 is a cross-sectional view of the toilet apparatus of the present embodiment,

FIG. 10 is a cross-sectional view of the toilet device of the first comparative example. FIG. 9 and FIG. 10 are schematic diagrams for explaining the range in which the user's line of sight can be seen when the toilet bowl is being squatted in front of the toilet bowl 800. FIG.

First, a comparative example will be described. In the first comparative example shown in FIGS. 6, 8, and 10, the main body 400 extends over the bowl 810 of the toilet bowl 800, and a region 400P indicated by a broken line is formed. The rear part of the opening of bowl 810 is blocked. However, if the main body 400 protrudes above the bowl 810 in this way, small water is likely to be applied to the main body 400 when the male is standing. 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 is also attached to the back side of the area 400P that protrudes in this way. There is room for improvement in terms of cleanability.

[0032] Many Western-style toilet bowls are provided around the rim portion at the upper end of the bowl 810 so that the protruding portion surrounds a part of the opening or the entire opening. Therefore, when cleaning the bowl 810 of the toilet bowl 800, it is desirable that the upper end of the protrusion provided on the rim 820 can be easily cleaned with a rag or brush.

[0033] When the main body 400 protrudes above the bowl 810 in this manner, even if dirt is attached to the upper rear part of the bowl 810, it is difficult to clean the portion. . In other words, in the case of the comparative example shown in FIG. 10, the rim 820 at the upper end of the bowl 810 remains behind the overhanging area 400P of the main body even when the user squats in front of the toilet 800. Hidden and invisible. For this reason, in order for the user to clean the rim portion 820 under the area 400P, the user must bend in a more leaning posture.

On the other hand, in the present embodiment, as shown in FIGS. 5, 7, and 9, the front surface of the main body 400 is retracted to form the curved concave surface 402, thereby allowing the male to stand up. In the case of small-scale use, small water is difficult to force and does not give a visual stenosis to the user. In addition, as shown in FIG. 3 and the like, by raising the central portion of the curved concave surface 402, even if a small amount of water is exerted on the main body 400 when the male is standing, the central portion of the curved concave surface 402 is A nearby tall part can receive a small amount of water and drop it into bowl 810. That is, it is possible to suppress the small water from splashing on the inclined surface 408 of the main body 400, and to reduce the contamination due to the small water as much as possible.

[0035] By retreating the main body 400 in this manner, the adhesion of dirt can be suppressed, and the cleaning performance can be greatly improved. That is, according to the present embodiment, as shown in FIG. 9, 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. Accordingly, the user can cleanly clean the back of the bowl 810 using a rag or a brush in the posture, and can confirm reliably and easily that the dirt has been removed. In the present embodiment, the amount of protrusion of the main body 400 onto the bowl 810 is suppressed, so that it is easy to clean dirt and the like adhering to the back side of the protrusion. For example, when cleaning with a rag or the like, the user can quickly wipe the left and right with the rag on the back of the main body 400. In the toilet bowl 800 of this embodiment, a toilet flushing water introduction path 826 formed by a shelf 822 and an overhang 824 is provided on the rim 820 at the upper edge of the bowl 810. By flushing toilet flush water along the toilet flush water introduction path 826, the bowl 810 can be washed so as to form a swirling flow by spreading the toilet flush water substantially all around the bowl 810. And because the top edge of the bowl is smoothly overhanging, it is easy to wipe off the dirt and the toilet bowl 800 can be cleaned very easily.

[0037] Further, in the present embodiment, the curved concave surface 402 is slightly protruded toward the bowl side from the opening end of the bowl 810, so that the opening of the bowl 810 is hardly blocked, It is possible to effectively suppress small water and the like from entering the gap between the upper surface of the open end of the bowl 810.

FIG. 12 is a cross-sectional view of the toilet device of the second comparative example.

[0039] First, a comparative example will be described. The second comparative example shown in FIG. 12 is a prior art in which the main body 400 is applied to a toilet seat device that does not protrude from the opening end of the toilet as described above with respect to the background art. Correspond. That is, in this comparative example, the front surface of the main body 400 does not protrude toward the bowl 810 and coincides with the open end of the bowl 810. However, if this is done, the gap between the main body 400 and the open end of the bowl 810 is completely exposed, so that the small water 880 is likely to enter directly into the gap. In particular, when a man is used in a standing position, small water 880 may also be applied to this gap due to high positional force, and there is a risk that small water with strong water will penetrate deep into the gap. Of course, it is also possible to install packing etc. so that small water does not enter this gap. Even in this case, if small water enters the packing area, It is possible that a small amount of water can penetrate beyond the packing due to water.

On the other hand, in the toilet apparatus of the present embodiment, as shown in FIG. 11, the front surface of the main body 400 has a curved concave surface 402 and slightly forward of the opening end of the bowl 810. By projecting, the gap between the main body 400 and the open end of the bowl 810 is necessarily hidden by the main body 400. As a result, it is possible to almost completely prevent the small water 880 from directly exerting on the gap between the main body 400 and the open end of the bowl 810 even when the male is standing up. In particular, When small children are standing, small water is also applied to low position force, but even in such a case, small water is applied to the gap between the main body 400 and the open end of the bowl 810. Can be prevented. As a result, small water or the like can be prevented from entering the gap as much as possible, and the generation of odor can be suppressed and a clean state can be maintained.

In addition, if small water enters the gap between the main body 400 and the open end of the bowl 810, the small water may flow to the side of the main body 400 and flow out of the lateral side force of the toilet 800 and spill on the floor. However, in the case of this example, since small water is not directly applied to the gap between the main body 400 and the opening end of the bowl 810, the small water does not flow out of the toilet through the gap.

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 closer to the bowl 8 10 side than the opening end of the bowl 810. Slightly protruding. If the protrusions to the bowl 810 at the left and right front ends of the curved concave surface 402 are a and b, and the protrusion to the bowl 810 near the center is c, a and b are relatively small, and c is relatively Can be bigger. In this way, it is possible to effectively prevent small water or the like from entering the gap between the main body 400 and the opening end of the bowl 810 while being substantially continuous with the opening shape of the bowl 810. This is because when the male is used in a standing position, the small water is mainly directed toward the center, 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. This also makes it easy to secure a space (protrusion) for drainage and deodorization.

Specifically, for example, a and b can be about several millimeters to about 10 millimeters, and c can be about 10 millimeters to about several tens of millimeters. If the curved concave surface 402 is slightly projected in this way, small water can be prevented from entering the gap between the main body 400 and the open end of the bowl 810 as much as possible. Furthermore, it is possible to secure drainage from the main body 400 to the bowl 810 and to secure a deodorizing air inlet for the deodorizing function.

[0043] Further, by limiting the amount of protrusion of the main body 400 to the bowl 810 in this way, For example, it is possible to evenly apply the dust cloth to the back side of the main body 400 within the range of the tip force of the user's finger up to the first joint. That is, the user applies a rag to the tip of the finger while keeping the first joint of the finger lightly bent, and slides the rag along the curved concave surface 402 of the main body 400 to the left and right. It is possible to reliably clean the back side of the rim and the upper end of the rim 820 adjacent thereto. The curved concave surface 402 constitutes a curved surface that is substantially continuous with the bowl 810, so that the cleaning can be performed smoothly and reliably without the need for a dust cloth to be applied.

[0044] In the present invention, a structure for preventing the entry of small water can be further added to the front edge of the main body 400 of such a sanitary washing device.

FIG. 14 is a partially enlarged cross-sectional view showing the vicinity of the front edge of the main body 400.

FIG. 16 is a schematic view of the central portion of the curved concave surface 402 when the downward force is also viewed.

That is, in this specific example, the wall 790 for preventing the entry of small water is provided below the front edge of the main body portion 400 in a shape with the front surface recessed like the curved concave surface 402. . The wall 790 is provided so as to hang down into the bowl 810 with the main body 400 attached to the toilet bowl 800. By providing such a wall 790, the gap between the main body 400 and the open end of the bowl 810 can be almost completely hidden, and the small water can be almost completely prevented. In addition, even when small water on the main body 400 flows downward on the surface of the curved concave surface 402, the small water flows down the surface of the wall 790 and falls down from the tip of the wall 790 by 810 mm. . In other words, it is possible to prevent the main body 咅 400 〖力 / / J ヽ hydraulic power S to go around the back of the main body 咅 400 and enter the gap with the toilet bowl 800. In this respect, it can be said that the wall 790 can also prevent indirect entry of small water.

In FIG. 14, a nozzle unit 610 is shown. In addition, the case plate 770 is appropriately provided with a packing 776 that has a force such as rubber, and can prevent intrusion of water or the like. In this specific example, the wall 790 is a force provided on the case plate 770. The present invention is not limited to this, and the wall 790 may be formed by extending a part of the case cover 430. In this case, the wall 790 may be formed integrally with the curved concave surface 402.

[0047] Hereinafter, another specific example of the structure for preventing the entry of small water will be described. FIG. 17 is a partially enlarged cross-sectional view showing the vicinity of the front edge of the main body 400 that works on the second specific example.

FIG. 18 is a schematic view of the curved concave surface 402 as viewed from the front.

FIG. 19 is a schematic view of the central portion of the curved concave surface 402 as viewed from the downward force.

In this specific example, the front edge of the case plate 770 is provided with a shape in which the front surface is recessed, similar to the inclined portion 792 force curved concave surface 402 protruding downward. Providing such an inclined portion 792 can also more reliably hide the gap between the main body 400 and the open end of the bowl 810, and more reliably prevent small water from being applied. Also in this specific example, when the small water applied to the main body 400 flows down the surface of the curved concave surface 402, the small water flows down the front 792A of the inclined portion 792 and flows down the inclined portion 792. Tip force also falls into bowl 810. In other words, it was possible to prevent the main body 咅 400 from getting into the gap with the toilet bowl 800 by going around the back side of the main body 咅 400.

[0049] In order to prevent small water from entering the back surface of main body 400, inclined portion 792 needs to have a certain height. However, if the ramp 792 is too high, it can be seen when used in standing positions for men and children, and can be used for small purposes. Since the toy-shaped drainage portion 771 described later is provided on the front surface 792A of the inclined portion, it is desired to avoid the inclined portion 792 being targeted. In view of this, the front surface 792A of the inclined portion is inclined 47 degrees rearward with respect to the horizontal direction, thereby making the inclined portion 792 invisible to the eyes of a standing person. In other words, in the front view of FIG. 18, the drainage section 771 is arranged so that the drainage section 771 is not visible to the adults and children in the power standing position.

Furthermore, in this specific example, there is an advantage that the back surface of the main body 400 protruding from the bowl 810 can be easily cleaned with a rag or the like!

FIG. 20 is a partially enlarged cross-sectional view showing the vicinity of the front edge of the main body 400 that is applied to the third specific example.

FIG. 21 is a cross-sectional view showing the vicinity of the tip further enlarged.

Also in this specific example, an inclined portion 792 that protrudes downward is provided at the front edge of the case plate 770 in the shape of a concave front surface, similar to the curved concave surface 402. Further, in this specific example, a draining groove 794 is provided on the rear surface 792B of the inclined portion 792. this By providing such a drain groove 794, it is possible to effectively prevent water from scooping up the rear surface 792B of the inclined portion 792. That is, most of the water that flows down the front surface 792A of the inclined portion 792 is the force that causes the tip force of the inclined portion 792 to fall into the bowl 810. Sometimes it goes up. The water that has soared up the rear surface 792B in this way may enter the gap between the main body 400 and the toilet bowl 800. On the other hand, according to this specific example, by providing the draining groove 794 on the rear surface 792B of the inclined portion 792, the water that tries to scoop up the inclined portion 792 is blocked by the draining groove 794, so The rise can be effectively prevented. The drain groove 794 in this specific example can effectively prevent scooping up and turning around the rear surface 792B of the inclined portion 792 when the flow rate of water is particularly small.

In this specific example, the draining groove 794 may be formed so that the front surface 794A of the draining groove 794 (see FIG. 21) is a substantially vertical surface. That is, the water taken into the draining groove 794 is likely to fall into the bowl 810 via the substantially vertical front surface 794A.

FIG. 24 is a schematic view of the curved concave surface 402 as viewed from below.

That is, the draining groove 794 extends the rear surface 792B of the inclined portion 792 along the curved concave surface 402, and both ends thereof are bent forward and open to the curved concave surface 402. In this way, the water taken into the draining groove 794 can be dropped into the bowl 810 more efficiently.

FIG. 25 is a partially enlarged cross-sectional view showing the vicinity of the front edge of the main body 400 that is applied to the fourth specific example.

Also in this specific example, an inclined portion 792 that protrudes downward is provided on the front edge of the case plate 770 so as to have a concave front surface, similar to the curved concave surface 402. Further, in this specific example, a wall 796 is provided at the tip of the inclined portion 792. The wall 796 is provided so as to hang down into the bowl 810 with the main body 400 attached to the toilet bowl 800. By providing such a wall 790, the gap between the main body 400 and the opening end of the bowl 810 can be almost completely hidden, and the small water is almost completely applied. Can be prevented. In addition, even when small water on the main body 400 flows downward on the surface of the curved concave surface 402, the small water flows down the surface of the wall 796 and falls down from the tip of the wall 790 by 810 mm. . In other words, it is possible to prevent the main body 咅 400 〖力 / / J ヽ hydraulic power S to go around the back of the main body 咅 400 and enter the gap with the toilet bowl 800.

[0057] Next, an embodiment in which the hot air for drying is efficiently delivered to the "wet" or the like will be described.

FIG. 26 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 gradually decreases as it approaches the left and right extending portions 404 that are large near the center. That is, the curved concave surface 402, which is a substantially vertical surface, has a shape that gradually decreases as it approaches the left and right extending portions 404 that are higher near the center. More specifically, the center of the curved concave surface 402 is about 45 mm, and the left and right end portions are about 13 mm high, and the ratio is about 7: 2.

In this way, by increasing the height of the central portion of the curved concave surface 402, even if a small amount of water is applied to the main body 400 when the male is standing up, the height of the tall portion near the center of the curved concave surface 402 is increased. Part can receive small water and drop it into bowl 810. That is, it is possible to suppress the small water from splashing on the inclined surface 408 of the main body 400, and the contamination by 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 that covers the curved concave surface 402 can be lowered to a low seating level.

[0058] On the other hand, two openings are provided adjacent to each other at 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 are an opening facing the outlet of the hot air duct and A hot air damper 470 is provided as a closing member that covers the opening. All of these are supported to be openable and closable, and in the standby state, both are closed. Then, when the water discharge nozzle advances in order to wash the “buttock” of the user sitting on the toilet seat 200, the nozzle damper 460 is opened by the force pushed by the water discharge nozzle or electrically. Further, when the hot air is blown from the hot air drying unit 620 toward the user's “buttock”, the hot air damper 470 is opened by the hot air or by the electric motor. [0059] 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. Or cover the two openings with a single damper.

In this way, by providing the nozzle damper 460 at the 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. it can. 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, it is necessary for the water discharge nozzle to have a two-stage structure in which the nozzle head and one cylinder part can be slid, or a multistage structure having more than that.

This nozzle unit 610 has a three-stage structure. That is, 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. The nozzle head 615 having the 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. When the water discharge nozzle is retracted as shown in FIG. 27 (a), the water discharge nozzle is accommodated in the main body 400 and is advanced as shown in FIG. 27 (b). Open nozzle damper 460 (see Fig. 26) and advance into bowl 810.

[0061] Since such a water discharge nozzle has a multi-stage structure, the diameter of the nozzle is necessarily large.

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 raised, 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 “butt”.

[0062] 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, a hot air outlet that dries the user's "buttock" or the like is preferred. Can be in a suitable shape.

FIG. 28 is a schematic view illustrating the shape of the hot air outlet. That is, FIG. 10A illustrates the air outlet in the present embodiment, and FIG. 10B illustrates the air outlet of the comparative example.

[0063] In order to blow out hot 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. 28 (b), it is unavoidable to adopt a blower outlet having a small width in the vertical direction and flat in the horizontal direction. For example, in the case of the air outlet of the comparative example illustrated in FIG. 28 (b), the width A in the vertical direction is 10 millimeters, whereas the width B is 43 millimeters, and has an opening flat in the lateral direction.

[0064] However, as described above with reference to FIGS. 3 and 26, the front surface of the main body 400 is moved backward to form the curved concave surface 402, so that the position of the blow-out port also moves away from the user's “tail” and other forces. Become. In such a case, if a flat air outlet as shown in Fig. 28 (b) is used, the hot air diffuses in the left and right directions, so that a sufficient amount of hot air reaches the user's buttock. This becomes difficult.

On the other hand, according to the present embodiment, as shown in FIG. 28 (a), it is possible to provide a blower outlet in which the vertical width and the horizontal width are close to each other. This is also a force obtained by raising the vicinity of the center of the curved concave surface 402 and providing the nozzle damper 460 at this high portion. For example, in the case of the air outlet illustrated in FIG. 28 (a), 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 concentrated hot air can be blown out. As a result, the hot air converged on the user's “buttock” can be transmitted from the bay curved concave surface 402, which has been forced to move backward, by also seeing the user ’s “butt” force.

[0066] The opening area of the outlet of the comparative example shown in FIG. 28 (b) is about 430 square millimeters, whereas the opening area of the outlet shown in FIG. 28 (a) is about 480 millimeters. It is. In other words, by installing the nozzle damper 460 in the tall part near the center of the curved concave surface 402, the vertical dimension of the outlet can be increased, and the opening area can be increased while the aspect ratio of the opening is close to 1. It becomes possible.

The effect of converging warm air in this embodiment will be described in detail later with reference to specific examples. [0067] Next, an example of the internal structure of the sanitary washing device of the present embodiment will be described.

FIG. 29 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. Further, 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.

Note that, as shown in FIG. 20 and FIG. 21, the motor 472 that drives the hot air damper 470

(See FIG. 51 and FIG. 52) is installed under the nozzle unit 610. In this way, the space under the nozzle unit 610 can be used effectively, and the driving force can be transmitted near the hot air damper 470.

As described above with reference to FIG. 27, the nozzle unit 610 has a water discharge nozzle that can freely move back and forth, and has a role of cleaning water by spraying water on the “butt” of the user sitting on the toilet seat 200. The hot air drying unit 620 has an outlet as described above with reference to FIG. 28, and plays a role of applying hot air to a user's “butt” seated on the toilet seat 200 and drying it. The deodorizing unit 630 has a function 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, and the pump unit 650 imparts pulsation to the water, and the nozzle unit 610 supplies this pulsating water.

Further, an auxiliary operation unit (not shown) is appropriately provided on the side surface of the case cover 430. The auxiliary operation unit is equipped with a switch that operates the “wet” cleaning by the nozzle unit 610, and controls the operation of the sanitary cleaning function even when it cannot be operated by a remote control (not shown), for example. It is possible.

On the other hand, an electric opening / closing unit 720 and a toilet cleaning valve unit 730 are provided at the rear of the case cover 430. The electric opening / closing unit 720 has a function of opening and closing the toilet lid 300. Toilet bowl valve unit 730 controls the supply of flush water to the toilet bowl 800 Have a role to play. In other words, the toilet device of this specific example has a so-called “direct water supply type” structure, and supplies water supplied from the water supply to the toilet bowl 800 via the toilet flushing valve unit 730 without providing a low tank or the like. Perform cleaning. However, the present invention is not limited to this, and includes a sanitary washing device that can be attached to a low tank type toilet.

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

[0074] Further, drainage may occur in the main body 400 having such various mechanisms. For example, the nozzle unit 610 has a nozzle cleaning chamber at its tip, 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 drainage portion 771 provided at the center of the front end of the case plate 770.

[0075] At this time, by providing the wall 790, the inclined portion 792, the drain groove 794, the wall 796 and the like as described above with reference to FIGS. Can be prevented. That is, it is possible to prevent water discharged from the drainage part 771 from entering the gap between the main body part 400 and the toilet 800.

Further, the valve unit for supplying 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 if the water pressure in the drainage system rises above a predetermined value.

[0077] When the sanitary washing device 100 has a larger width than the toilet bowl 800, the vacuum breaker and water that also releases the safety valve force can be drained to the outside from the protruding portion. is there. However, as illustrated in Fig. 1 and Fig. 7, if the width of the sanitary washing device 100 is made as compact as the width of the toilet bowl 800, drainage from the vacuum breaker and safety valve can also be taken out of the lateral force of the sanitary washing device 100. It becomes difficult.

On the other hand, in the present specific example, water released from the vacuum breaker or the safety valve force can be drained into the bowl 810. FIG. 30 is a schematic view showing a state in which the upper case and the internal mechanism of the main body 400 are removed and the case plate (mounting board) 770 is exposed.

The drainage hole 773 is provided in the part that protrudes to the bowl 810 side from the open end of the bowl 810, and drainage from the vacuum breaker and safety valve can be discharged to the bowl 810 by connecting to the vacuum breaker and safety valve with a drainage tube . In addition, by providing a toy-shaped drainage section 771 at the center end of the case plate 770 that protrudes toward the bowl 810 from the opening end of the bowl 810, the nozzle cleaning chamber 617 (see Fig. 27) force of the water discharge nozzle Wastewater can also be discharged into 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.

As described above, the main body 400 slightly protrudes toward the bowl 810 from the opening end of the bowl 810, so that 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 drain tube from the safety valve.

FIG. 31 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. 31 (a), when the drainage hole 773 is provided under the part where the curved concave surface 402 is low, the drainage tube 662 hits the case cover 430 as shown by the broken line. May collapse and may not drain well. On the other hand, as shown in FIG. 31 (b), when the drainage hole 77 3 is provided below the portion where the curved concave surface 402 is high, the case cover 430 and the drainage tube 662 are shown as indicated by the broken line. Since there is a margin between the drainage tube 662 and the drainage tube 662, the drainage tube 662 can be drained reliably without being crushed.

Next, the hot air drying unit provided in the present embodiment will be described in more detail with reference to specific examples.

FIG. 32 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 outlet 626. In the present embodiment, as described above with reference to FIG. 28, the B outlet 626 is adjacent to the water discharge nozzle and is provided at a height in the vicinity of the center of the curved concave surface 402.

FIG. 33 is a schematic diagram showing the direction of hot air discharged from the air outlet 626.

In the present embodiment, as shown in FIGS. 33 (a) to (c), the air outlet 626 provided behind the hot air damper 470 (see FIG. 26) provided near the center of the curved concave surface 402 is used. In addition, 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 aspect ratio of the opening dimension that the air outlet 626 is not flat in the left and right (horizontal) direction is close to 1, the discharged hot air H does not spread in the left and right (horizontal) direction, and the concentrated hot air H is delivered far away. be able to. Further, the hot air H can be directed upward by increasing the vertical dimension of the air outlet 626. As a result, a sufficient amount of warm air H can be delivered to the “buttock” of the user sitting on the toilet seat 200.

FIG. 34 to FIG. 36 are schematic diagrams showing the results of experiments conducted by the present inventors.

34A is a schematic view of the present embodiment, and FIG. 34B is a schematic view of the distribution of hot air discharged from the hot air drying unit of the sanitary washing apparatus of the comparative example.

FIG. 35 (a) is a schematic view of the present embodiment, and FIG. 35 (b) is a schematic view of the distribution of the hot air discharged from the hot air drying unit of the sanitary washing device of the comparative example as viewed from above.

FIG. 36 (a) is a schematic view of the present embodiment, and FIG. 36 (b) is a schematic view of the distribution of the warm air H from which the warm air drying unit force of the sanitary washing device of the comparative example is also released.

Here, the hot air drying unit of the present embodiment has the air outlet shown in FIG. 28 (a), and the hot air drying unit of the comparative example has the air outlet shown in FIG. 28 (b). . In each figure, the center position of the “tail” of the user sitting on the toilet seat is represented by the symbol C.

FIG. 34 shows that the center position of the hot air H is higher in this embodiment than in the comparative example. As described above with reference to FIG. 28, this is also the force that can increase the vertical dimension of the opening by providing the outlet 626 in a tall portion near the center of the curved concave surface 402. In this specific example (see Fig. 7), the position of the outlet 626 is more backward than in the comparative example (see Fig. 8), so as shown in Fig. 34 (b), If the air outlet is provided at the position of the hot air damper 470 in this specific example, the center of the hot air H is lowered at the position of the user's “butt”. On the other hand, in the case of this specific example, the center of the hot air H can be increased by about 15 millimeters at the position of the user's “buttock” compared to the comparative example. By raising the center of the hot air H in this way, the hot air H can be reliably applied to the “butt” of the user.

In addition, as shown in FIG. 35 (b), in the comparative example, the warm air H spreads in the left-right (horizontal) direction, whereas as shown in FIG. 35 (a). In this specific example, the hot air H does not spread in the left-right direction, and the hot air H that is converged can be delivered to the position of the user's “butt”.

As a result, in this specific example shown in FIG. 36 (a), compared to the comparative example shown in FIG. Can be surely reached. That is, according to the present embodiment, as described above with reference to FIG. 28, the vicinity of the center of the curved concave surface 402 is raised, and the hot air damper 470 is provided at this high portion, so that the vertical direction of the hot air outlet 626 is increased. By expanding the dimensions and bringing the aspect ratio close to 1, it is possible to deliver the concentrated hot air H far away.

Next, an embodiment for controlling the opening and closing of the opening and closing plate for the water discharge nozzle and the opening and closing plate for drying hot air will be described.

FIG. 37 is a block diagram illustrating the main configuration of a sanitary washing device that works according to the present embodiment.

FIG. 38 is a perspective view of the front portion of the main body of the sanitary washing device.

The sanitary washing device 100 of the present embodiment includes human body detection sensors 420 and 500, a nozzle unit 610, a hot air drying unit (hot air generator) 620, drive means (second drive means) 472, A toilet lid opening / closing unit 720 for opening / closing the toilet lid, and a toilet seat opening / closing unit 780 for opening / closing the toilet seat. The human body detection sensors 420 and 500 detect a user near the sanitary washing device 100 or a user seated on the toilet seat. Nozzle unit 610 has a body force of the sanitary washing device that is driven by the driving force transmitted from nozzle motor (first driving means) 619. It has an existing water discharge nozzle and sprays water toward the “butt” of the user sitting on the toilet seat. The nozzle damper (first opening / closing plate) 460 that closes the opening (first opening) 402A formed in front of the nozzle unit 610 is urged to be closed by a spring, as will be described in detail later. In a state in which is stored, it is in a closed state as shown in FIG. Then, when the water discharge nozzle advances in the direction of arrow A (FIG. 37), the nozzle damper 460 is pressed by the back surface and opens as shown in FIG. 38 (b).

On the other hand, the hot air drying unit (warm air generating device) 620 is dried by blowing hot air toward the “butt” of the user who is also sitting on the toilet seat. The driving means (second driving means) 472 includes a hot air damper (second opening / closing plate) 470 that closes the opening (second opening) 402B formed in front of the hot air outlet of the hot air drying unit 620. Open and close. Fig. 38 (c) shows the hot air damper 470 opened. In the specific example shown in FIG. 38, both the nozzle damper 460 and the hot air damper 470 are supported so as to be rotatable about a substantially horizontal rotation axis. The dampers 460 and 470 are both opened by rotating upward.

The operations of these elements are controlled by the control unit 640. Further, the control unit 640 receives a signal from the operation unit 900 such as a remote control, and can execute an operation in accordance with a user instruction. In this embodiment, the control unit 640 includes a nozzle damper 46.

0 and controls the timing and sequence of opening and closing the hot air damper 470.

FIG. 39 to FIG. 41 and FIG. 43 are flowcharts illustrating the contents of the control mode performed by the control unit 640. In the specific example shown in FIG. 39, first, the hot air damper 470 is in an open state (step S102). Typically, this is a state in which the user is drying the “wet” or the like using the hot air drying function, and the hot air damper 470 receives power from the driving means 472 and receives the power as shown in FIG. It is in the open state as shown in). In this state, when the user issues a “cleaning” command using the water discharge nozzle (step S104), the control unit 640 first closes the hot air damper 470 (step S106). After that, the water discharge nozzle is advanced to open the nozzle damper 460. In other words, if a washing command such as “wet” is issued during warm air drying, the water discharge nozzle should not be immediately advanced to open the nozzle damper 460. After closing the hot air damper 470, the water discharge nozzle is advanced and the nozzle is opened. As shown in FIG. 38, the nozzle damper 460 and the hot air damper 470 are both provided adjacent to the curved concave surface 402 of the main body 400, so the nozzle with the hot air damper 470 opened This is because if the damper 460 is also opened, they may collide with each other and lose their dynamic force, or may be damaged, deformed, or damaged.

On the other hand, in this specific example, by closing the hot air damper 470 and then opening the nozzle damper 460, it is possible to avoid the collision of these dampers 460 and 470 and to operate the sanitary washing apparatus 100 smoothly. it can.

[0093] The timing of the step of closing the hot air damper 470 (step S106) and the step of opening the water discharge nozzle and opening the nozzle damper 460 (step S108) can be appropriately determined. For example, as shown in FIG. 38 (a), the hot water damper 470 may be closed completely before the advance of the water discharge nozzle, or the hot water damper 470 may be closed before the hot air damper 470 is completely closed. It is also possible to advance and start opening the nozzle damper 460. In other words, the hot air damper 470 and the nozzle damper 460 do not collide! If the opening angle is within the range, the damper 460, 470 force, even if the gap is open, there is no problem! ,.

Further, according to the present embodiment, the open / closed state of the nozzle damper 460 can be estimated by, for example, the number of pulses applied to the stepping motor 619 that advances and retracts the water discharge nozzle. Similarly, the open / closed state of the hot air damper 470 can be estimated from the number of pulses applied to the stepping motor provided as the driving means 472.

Next, in the specific example shown in FIG. 40, first, the nozzle damper 460 is in an open state.

(Step S202). This is the state shown in FIG. 38 (b), and is typically a state in which the user cleans “wet” or the like with the water discharge nozzle. In this state, when the user issues a “dry” command using the hot air drying unit 620 (step S204), first, the water discharge nozzle moves backward to close the nozzle damper 460 (step S206). After pressing, open the warm air damper 470. In other words, if a drying command such as “wet” is issued while cleaning with the water discharge nozzle, the hot air damper 470 is opened immediately and the water discharge nozzle is moved backward without starting the hot air drying. The nozzle damper 460 is closed and the hot air damper 470 is opened. In this way, the nozzle damper 460 and hot air damper The sanitary washing device 100 can be operated smoothly by avoiding the collision of the par 470.

In this specific example as well, the timing of the step of closing nozzle damper 460 (step S206) and the step of opening hot air damper 470 (step S208) can be determined as appropriate. That is, as long as the opening angle is within a range where the hot air damper 470 and the nozzle damper 460 do not collide, both of the dampers 460 and 470 may be open.

Next, in the specific example shown in FIG. 41, first, the nozzle damper 460 is in an opened state.

(Step S302). As described above with reference to FIG. 40, this is typically a state in which the user cleans “wet” or the like with the water discharge nozzle. In this state, when the user issues a “dry” command using the hot air drying unit 620 (step S304), the hot air damper 470 is opened as it is (step S306), and hot air drying is started. (Step S308). That is, while the nozzle damper 460 is opened and the water discharge nozzle is advanced, the hot air damper 470 is opened and the hot air is blown out.

FIG. 42 is a partially enlarged perspective view showing the state of hot air drying (step S308) in this example.

In the process of reaching this state, first, the nozzle damper 460 is opened when the three-stage water discharge nozzle including the nozzle head 611, the first cylinder portion 612, and the second cylinder portion 613 advances (step S302). . Then, after the nozzle damper 460 is opened, the hot air damper 470 is opened by the driving force from the driving means 472. When the hot air damper 470 is fully opened, the tip of the hot air damper 470 comes into contact with the nozzle damper 460. However, since the nozzle damper 460 is biased in the closing direction by the spring only, the hot air damper 470 further lifts the nozzle damper 460 against the spring biasing force. At this time, since only the urging force of the spring acts between the hot air damper 470 and the nozzle damper 460, it is easy to pull and damage these dampers 460 and 470. No worries.

[0099] As described above, the nozzle damper 460 and the hot air damper 470 may be opened at the same time. By blowing hot air in this state, hot air drying can be performed. According to this specific example, after the “dry” command (step S304), the nozzle is moved backward to The hot air damper 470 can be opened and the hot air can be blown out immediately without closing the sill damper 460. Therefore, if the hot air drying can be started quickly, the effect can be obtained.

Next, also in the specific example shown in FIG. 43, first, the nozzle damper 460 is in an open state (step S402). As described above, this is typically a state in which the user cleans “wet” or the like with the water discharge nozzle. In this state, when the user's power is also instructed to “dry” using the hot air drying unit 620 (step S404), as in the specific example described above with reference to FIG. Opens (step S306). Then, the water discharge nozzle is retracted (step S408), and hot air drying is started (step S410).

FIG. 44 is a partially enlarged perspective view showing the state of hot air drying (step S410) in the present specific example.

As described above with reference to FIG. 42, in the process of reaching this state, first, a three-stage water discharge nozzle consisting of the nozzle head 611, the first cylinder portion 612, and the second cylinder portion 613 has advanced, so that the nozzle The damper 460 is opened (Step S402). When the hot air damper 470 is opened by the driving force from the driving means 472, the hot air damper 470 further lifts the nozzle damper 460 against the urging force of the spring. That is, the nozzle damper 460 is lifted by the hot air damper 470 and the water discharge nozzle force is also separated. Therefore, as shown in FIG. 44, even when the water discharge nozzle is retracted and stored in the main body 400, the nozzle damper 460 is kept in contact with the hot air damper 470 and kept open.

[0102] In this state, as described above with reference to FIG. 42, since only the urging force of the spring acts between the hot air damper 470 and the nozzle damper 460, these dampers 460, 470 There is no need to worry about being scratched or damaged.

[0103] Also in this specific example, the effect that hot air drying can be started quickly after cleaning by the water discharge nozzle is obtained. Furthermore, in this specific example, since the water discharge nozzle is retracted, the hot air is not blocked by the water discharge nozzle. In addition, when cleaning “wetting” or the like, scattered dirt may adhere to the surface of the water discharge nozzle. Therefore, when the water discharge nozzle is moved backward after cleaning, It is desirable to clean the surface by spraying. For this purpose, it is better not to dry the water discharge nozzle too much. On the other hand, according to this example, since warm air is not applied to the water discharge nozzle, the water discharge nozzle is dried. No worries

In this specific example, the timing for retracting the water discharge nozzle (step S408) and the timing for starting the hot air drying (step S410) can be determined as appropriate. That is, the water discharge nozzle may be completely retracted and the power may be blown out with hot air, or the water discharge nozzle may be moved backward and the hot air is blown out simultaneously. Alternatively, the discharge of the water discharge nozzle may be started after the blowing of warm air is started. Even in this case, the time for the hot air to hit the water discharge nozzle is short, so there is less concern when the surface of the water discharge nozzle dries! /

[0105] The control relating to the opening and closing of the nozzle damper 460 and the hot air damper 470 has been described above with reference to FIGS. 38 and 44.

Next, a configuration for preventing collision of these dampers by changing the opening / closing direction of the nozzle damper 460 or the hot air damper 470 will be described.

FIG. 45 is a perspective view illustrating the opening / closing direction of the nozzle damper 460 and the hot air damper 470 in the present embodiment.

In this specific example, the nozzle damper 460 opens and closes around a substantially horizontal rotation axis. The hot air damper 470 opens and closes around a rotation axis that is substantially perpendicular thereto. Further, the rotating shaft of the hot air damper 470 is provided on the side far from the nozzle damper 460. That is, the nozzle damper 460 opens upward, and the hot air damper 470 opens to the right side by force. In this way, the hot air damper 470 opens away from the nozzle damper 460, so that they do not collide. That is, the nozzle damper 460 and the hot air damper 470 can be opened simultaneously.

In this specific example, the nozzle damper 460 opens and closes around a rotation axis that is substantially perpendicular to the horizontal direction, and the hot air damper 470 opens and closes around a rotation axis that is substantially horizontal. Further, the rotating shaft of the nozzle damper 460 is provided on the side far from the hot air damper 470. That is, the nozzle damper 460 opens to the left and the hot air damper 470 opens upward. In this way, the nozzle damper 460 moves away from the hot air damper 470. Since it opens in the direction, both do not collide. That is, the nozzle damper 460 and the hot air damper 470 can be opened simultaneously.

In this specific example, both the nozzle damper 460 and the hot air damper 470 open and close around a rotation axis that is substantially perpendicular to the horizontal direction. Further, the rotating shaft of the nozzle damper 460 is provided on the side far from the hot air damper 470, and the rotating shaft of the hot air damper 470 is also provided on the side far from the nozzle damper 460. That is, the nozzle damper 460 is directed to the left and the hot air damper 470 is directed to the right. In this way, since the nozzle damper 460 and the hot air damper 470 are both opened in a direction to move away from each other, they do not collide with each other.

[0109] While the rotation axes of these dampers 460 and 470 are substantially vertical, the rotation axis of the nozzle damper 460 is provided near the hot air damper 470, and the rotation axis of the hot air damper 470 is close to the nozzle damper 460. It may be provided on the side. That is, even if the nozzle damper 460 and the hot air damper 470 are opened in a direction approaching each other, there is a case where the collision does not occur depending on the opening angle required for the dampers 460 and 470.

The control performed by the control unit 640 and the opening / closing directions of the nozzle damper 460 and the hot air damper 470 have been described above in the present embodiment.

Hereinafter, the embodiment of the present invention will be described in more detail with reference to specific examples. The operation of the nozzle unit 610 and the hot air drying unit 620 is performed by operating a control unit (not shown) provided in the main body 400. Execution can be set by appropriately operating it, and it can also be executed by operating a remote control installed on the wall of the toilet.

FIG. 48 is a schematic diagram showing a specific example of the remote controller.

The remote controller 900 of this specific example includes a “tail” switch 902, a “soft force” switch 904, a “bidet” switch 906, a “stop” switch 908, a “dry” switch 910, and the like. When the “wet” switch 902, “soft force” switch 904 or “bidet” switch 906 is operated, the main body 400 force water discharge nozzle advances and water is sprayed to the user's “tail”. In addition, "dry" When the switch 910 is operated, the hot air damper 470 opens and hot air blows out toward the “buttock”. When the “stop” switch 908 is operated, cleaning by the water discharge nozzle and hot air drying are stopped.

Therefore, for example, when the “wet” switch 902 is operated and then the “dry” switch 910 is operated, the control described above with reference to FIGS. 40 to 44 is executed, for example. Further, when the “drying” switch 910 is operated, and then the “wet” switch 902 is operated, the control described above with reference to FIG. 39, for example, is executed.

On the other hand, in this specific example, as shown in FIG. 1 and FIG. 3, a recessed portion 410 is formed on the upper surface of the main body 400, and a human body is embedded in the recessed portion 410. A detection sensor 500 is provided. In the state where the toilet lid 300 is closed, the human body detection sensor 500 detects the presence of the user through the transmission window 310 provided near the base.

In this specific example, as shown in FIG. 3, the main body 400 has a shape retreated in accordance with the open end of the bowl 810 of the toilet bowl 800. That is, the main body 400 is installed at the upper rear of the toilet 800, and its front surface slightly protrudes toward the bowl 810 side from the open end of the bowl 810 along the shape of the open end of the bowl 810 of the toilet 800. The curved concave surface 402 is curved in a concave shape. Here, “rear” means the side where the mouth tank, flush valve, etc. are usually installed, as shown in FIG. 1. In the normal use mode, it is far from the user. Means the side.

[0115] On the left and right sides of the curved concave surface 402, extending portions 404 extending forward along the opening end of the bowl 810 are provided. The curved concave surface 402 has a shape that gradually decreases as it approaches the left and right extending portions 404 that are higher in the center.

[0116] In the high portion near the center of the curved concave surface 402, an opening for advancing and retracting the water discharge nozzle

(Second opening) 402B and a nozzle damper (second opening / closing plate) 460 as a closing member covering the opening 402B are provided, and the right-hand opening (first opening) 402A has a hot air damper. (First opening / closing plate) 470 is provided.

[0117] Hereinafter, an example of control executed in such a sanitary washing apparatus will be described.

FIG. 49 is a timing chart illustrating an example of the control executed by the control unit 640. In the present embodiment, the control described above with reference to FIGS. 40 and 39 is executed.

First, when the human body detection sensor 420 (see FIGS. 1, 3, and 22) detects that the user is seated on the toilet seat 200, the hot air damper is first opened and closed again (A). This is an initialization operation for surely closing the hot air damper 470, and at the same time, an effect of preventing the hot air damper 470 from sticking is obtained. In other words, the hot air damper 470 may be subjected to moisture when washing with a water discharge nozzle or when used in a male standing position. When the moisture penetrates into the gap around the hot air damper 470 and evaporates, the chlorinated component and the like remain, and the hot air damper 470 may stick to the movement. On the other hand, for example, as shown in FIG. 49, if the hot air damper 470 is opened and closed in response to the seating of the user, the sticking can be surely prevented.

[0119] Further, in the initialization operation (A) of the hot air damper 470, the hot air damper 470 is completely opened so as to be divided compared with the waveform of the hot air drying performed later. The opening angle is set relatively small. For initialization and prevention of sticking, the opening angle is small, and the opening angle can be reduced quickly, and can be executed without being noticed by the user.

[0120] After that, the user operates the “wet” cleaning switch (B) to start cleaning with the water discharge nozzle (C), and the user changes the water pressure (the “drying” switch is operated ( E) Then, as described above with reference to FIG. 40, the water discharge nozzle is retracted (F), the nozzle damper 460 is closed, and then the hot air damper 470 is opened (G), and the hot air motor and the hot air are The heater is activated and hot air is blown out (H), that is, even if the “dry” switch is operated during cleaning by the water discharge nozzle, the hot air damper 470 is not immediately opened and the water discharge nozzle is turned off. The hot air damper 470 is opened after retreating and closing the nozzle damper 460. This prevents the hot air damper 470 and the nozzle damper 460 from colliding with each other.

After that, when the user operates the “wet” switch again (I), the hot air fan and the hot air heater are stopped accordingly (J), and the hot air damper 470 is closed as described above with reference to FIG. ). Thereafter, the water discharge nozzle advances and cleaning is resumed (L). At this time, the collision between the hot air damper 470 and the nozzle damper 460 is prevented.

[0121] As explained above, after the user operates the “wet” cleaning switch, When the hose is operated, the hot air damper 470 is not immediately opened, but the nozzle damper 460 is closed and the hot air damper 470 is also opened by force, so that the collision of these dampers 460 and 470 can be surely prevented. Similarly, when the user operates the “wet” cleaning switch after operating the “drying” switch, these nozzles are operated by opening the water discharge nozzle, closing the nozzle damper 460, and opening the hot air damper 470. The collision of dampers 460 and 470 can be reliably prevented.

[0122] Note that, for example, when the user operates the "stop" switch after operating the "wet" cleaning switch, and then operates the "dry" switch, the control is performed according to the order of these instructions. Just do it. However, even in this case, if the “dry” switch is pressed immediately after the “stop” switch is pressed, the nozzle damper 460 may not be completely closed. Therefore, it is desirable to wait for a predetermined timing until the warm air damper 470 starts to open.

[0123] The example of the present embodiment has been described above.

Next, the configuration of each part of the sanitary washing device of the present embodiment will be described in detail with reference to specific examples.

FIG. 50 is a schematic cross-sectional view showing the open / close mechanism of hot air damper 470.

FIG. 51 is a perspective assembly diagram showing the drive mechanism of hot air damper 470. FIG. FIG. 52 is a schematic diagram showing attachment parts of the hot air damper 470 and the motor 472. FIG. 53 is a perspective view showing an assembly process for attaching the frame 480 to the case cover 430. FIG.

As described above with reference to FIG. 38, this specific example has a structure in which the nozzle damper 460 and the hot air damper 470 open and close around a substantially horizontal rotation axis.

As shown in FIG. 50, the main body 400 includes a case cover 430 and a case plate 770 that constitute a housing. Further, behind the hot air damper 470, an air outlet 622 of the hot air drying unit 620 is disposed. As described above, the hot air drying unit incorporates a fan and a heater, and blows out hot air from the air outlet 622 toward the “butt” of the user.

As shown in FIG. 52, the hot air damper 470 is rotatably supported by the frame 480 together with the nozzle damper 460, and the frame 480 is attached to the case cover 430. . The rotational axis of the rotational movement of the hot air damper 470 is provided above the air outlet 622. On the other hand, a motor (driving means) 472 is accommodated behind the hot air damper 470. The motor 472 is fixed to the case plate 770 via a mounting base 490. As the motor 472, for example, a stepping motor can be used, and in this specific example, it is disposed under the water discharge nozzle. When a stepping motor is used, it is easy to detect the open / closed state of the hot air damper 470 by the number of pulses. Further, as described above with reference to FIG. 49, it is easy to reduce the opening angle of the hot air damper 470 during the initialization operation.

A first lever 473 is coupled to the rotating shaft of the motor 472. The first lever 473 rotates within a predetermined range in accordance with the rotation operation of the motor 472. A second lever 474 is coupled to the tip of the first lever 473. A holding portion 475 is provided at the tip of the second lever 474. The holding portion 475 is coupled to a link shaft 476 provided on the upper back side of the hot air damper 470.

As shown in FIG. 50 (a), when the motor 472 rotates in the direction of arrow A from the state in which the hot air damper 470 is closed, the second lever 474 is pulled in the direction of arrow B. This pulling force is transmitted to the link shaft 476 of the hot air damper 470, and the hot air damper 470 rotates and opens in the direction indicated by the arrow. Fig. 50 (b) shows the hot air damper 470 fully open. In this state, the hot air blown from the air outlet 622 of the hot air drying unit 620 can be reliably applied to the “butt” of the user sitting on the toilet seat without being blocked by the hot air damper 470. 51 shows a state in the middle of assembly. After the assembly is completed, as shown in FIG. 51, when the first lever 473 is almost upright, the hot air damper 470 is in a closed state.

When assembling, first motor 472, first lever 473, second lever 474, and hot air damper 470 are attached to case plate 770. On the other hand, as shown in FIG. 53, with the nozzle damper 460 attached to the frame 480, the frame 480 is fixed to the case cover 430 using screws 483 or the like. The nozzle damper 460 is biased to the closed state by the biasing force of the spring 481.

Then attach the case cover 430 to the case plate 770 and connect it to the second lever 474. Install the assembled warm air damper 470 on the frame 480. If the structure is such that the hot air damper 470 and the nozzle damper 460 are fixed to the case cover 430 via the frame 480, high mounting accuracy can be obtained and assembly can be facilitated.

[0130] Here, as shown in FIG. 50, the power toilet seat 200 (see FIGS. 1 and 3) in which the inclined surface 408 is provided on the upper surface in front of the case cover 430 of the main body 400 is closed. , The lower surface of the toilet seat 200 is adjacent to the inclined surface 408. When the hot air damper 470 is opened, if the tip of the hot air damper 470 comes into contact with the lower surface of the toilet seat 200, it is not preferable in that abnormal noise or damage may occur. On the other hand, it is desirable that the warm air damper 470 is opened as large as possible so as not to block the warm air blown from the air outlet 622.

[0131] On the other hand, according to this specific example, the rotating shaft of the hot air damper 470 is provided above the outlet 622, and is further coupled to the second lever 474 by the link shaft 476 provided thereabove. As a result, it is possible to open the toilet seat 200 without much contact and without greatly blocking the air outlet 622.

[0132] The hot air damper 470 can be formed of, for example, a resin such as polypropylene. Further, the hot air damper 470 may be formed of stainless steel or aluminum whose surface is anodized. On the other hand, the frame 480, the first lever 473, the second lever 474, and the like can be formed of grease or the like.

[0133] Furthermore, according to this specific example, as shown in FIG. 22 and the like, the warm air damper 470 is provided at a high portion near the center of the curved concave surface 402, so that the user's “tail” or the like is provided. The hot air outlet to be dried can be formed into a suitable shape.

FIG. 54 is a schematic view of the nozzle damper 460 and the hot air damper 470 as viewed from above. The nozzle damper 460 and the hot air damper 470 attached to the frame 480 have curved surfaces along the curved concave surface 402 of the main body 400. And since these rotary shafts Cl and C2 are not parallel, if these dampers 460 and 470 are opened simultaneously, they may collide. On the other hand, in the present embodiment, the control unit 640 executes the control described above with reference to FIGS. 39 to 44 to prevent the dampers 460 and 470 from colliding with each other, or even if they interfere with each other, the damage or the failure is caused. The operation is realized without any occurrence.

[0134] The nozzle damper 460 and the hot air damper 470 mounting part and the opening / closing mechanism have been described above. Explained.

[0135] Next, an embodiment of a toilet device that can reliably perform deodorization and drainage of waste water will be described.

FIG. 55 is a perspective view of the inside of the main body 400 of the toilet device of the present embodiment as viewed from the rear.

A valve unit 690 is provided at the lower rear part of the case cover 430. The valve unit 690 serves to control the supply of water supplied from the water supply to the pump unit 650.

On the other hand, a DC (direct current) controller 700 and a driver unit 710 are provided in the upper part of the front part inside the case cover 430. 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 flushing water flowing to the toilet bowl 800. That is, the tray device of this specific example has a so-called “direct water supply type” structure, and does not provide a low tank or the like, but supplies the water supplied from the water tank through the toilet flush valve unit 730. Supply to 800 for cleaning.

FIG. 56 is a perspective view for explaining the structure of case plate 770.

Case plate 770 is fixed to the upper surface of toilet bowl 800. On the other hand, the toilet flushing valve unit 730 is supported by a toilet base plate 760 fixed to the rear side of the toilet 800, and is connected to the toilet 800 by a water supply pipe 735. Then, the toilet flushing valve nut 730 passes through an opening 775 provided in the case plate 770 and projects upward.

The electric opening / closing unit 720 and the toilet bowl cleaning valve unit 730 are provided at the rear of the main body 400. Then, as described above with reference to FIGS. 29 and 55, the sanitary washing function unit including the nozzle unit 610 is appropriately disposed below the front portion of the case plate 770 and the electric opening / closing unit 720. A toy-shaped drainage portion 771 is provided near the center of the front end of the case plate 770, and a deodorizing intake port 774 (see FIG. 29) is opened on the right side thereof. FIG. 57 is a schematic view of the central portion of the curved concave surface 402 of the main body 400 as viewed from the front. FIG. 58 is a schematic diagram enlarging the vicinity of the center.

That is, in the center of the curved concave surface 402, an opening for advancing and retracting the water discharge nozzle and a nozzle damper 460 as a closing member for covering the opening are provided, and on the right side, a hot air outlet and a hot air outlet are provided. A warm air damper 470 is provided as a closing member for covering the air. These are all supported to be openable and closable, and are all closed in the standby state. Then, when the nozzle unit 610 advances to clean the “buttock” of the user sitting on the toilet seat 200, the nozzle damper 460 opens. Also, when the hot air is blown from the hot air drying unit 620 toward the user's “buttock”, the hot air damper 470 is opened.

[0140] In the state where the nozzle damper 460 and the hot air damper 470 are closed, for example, even if a small amount of water is used, such as for men, the small amount of water enters the inside of the main body 400. In order to prevent this, the clearance S with the case cover 430 (see Fig. 58) should be less than 0.5 millimeters, for example.

[0141] A drainage section 771 is provided below the back side of the nozzle damper 460.

FIG. 59 is an enlarged cross-sectional view of the drainage section 771. In the figure, the mechanism in the main body 400 is omitted for convenience.

[0142] The drainage part 771 is formed in an extension part 770P in which the front end of the case plate 770 slightly extends downward. As can be seen from FIG. 57, the extended portion 770P of the case plate 770 is gently curved with the nozzle damper 460 as the center. As can be seen from FIG. 58, the tip of the drainage section 771 has a converging shape that collects water at the center and discharges it downward. In this way, by extending the front end of the case plate 770 downward and further converging the front end, the waste water generated in the main body 400 can be reliably dropped and discharged into the bowl 810. .

[0143] For example, in the nozzle unit 610, when the nozzle advances or retracts, drainage occurs when water is sprayed onto the nozzle body to wash the body. The drainage section 771 has a role of discharging this drainage into the bowl 810. In addition to this, for example, after the nozzle is advanced or retracted, the water outlet force is also injected by spraying water. In order to prevent “clogging” and stabilize the temperature of discharged water, the drainage can be discharged into the drainage section 771 force bowl 810. Furthermore, in the event that the water pressure rises above a predetermined value in the path for supplying water to the nozzle unit 610 and the safety valve operates, or in the unlikely event that water leaks, these wastewater is discharged from the drainage section 771 to the bowl 810. Can be reliably discharged.

[0144] On the other hand, according to the present embodiment, it is also possible to suppress draining of the drainage to the back side of the drainage part 771 (the side facing the toilet bowl 800 in Fig. 59). That is, if the drainage discharged from the drainage section 771 wraps around the back side of the case plate 770 as shown by arrow A in FIG. 59, there is a risk of entering the gap with the toilet bowl 800. Thus, the water that has entered the gap with the toilet bowl 800 may diffuse around the main body 400 and the rear side and leak outside the apparatus.

[0145] In contrast, according to the present embodiment, the tip of the case plate 770 is extended downward to form the extension portion 770P, and the drainage portion 771 having a converging shape is provided at the tip. As a result, the waste water generated inside the main body 400 can be reliably dropped and drained into the bowl 810 to prevent the water from being drowned on the back side.

[0146] Next, the deodorizing intake port will be described.

FIG. 60 is a schematic view of the case plate 770 viewed from the back side.

FIG. 61 is a cross-sectional view taken along line AA in FIG.

The deodorization inlet 774 is connected to the deodorization unit 630 and sucks the air in the bowl 810. The air in the bowl 810 sucked from the deodorizing intake port 774 through the filter 632 by the action of the exhaust fan reaches the catalyst unit from the exhaust duct 634 of the deodorizing unit 630. In the catalyst section, the odor is removed by decomposing or adsorbing organic gas components contained in the intake air and causing odor by the action of, for example, oxygen and ozone. The exhaust gas from which the odor has been removed is discharged from an exhaust port 440 (see FIG. 1) provided on the side surface of the main body 400.

In the present embodiment, the deodorizing intake port 774 is formed in an elongated crescent shape along the curved concave surface 402 formed on the front surface of the main body 400, as shown in FIG. Yes. By forming the deodorizing air intake 774 in such an elongated crescent shape, the amount of protrusion of the main body 400 to the bowl 810 is minimized, and the intake opening area required for deodorization is secured. Becomes easy. In other words, the main body 400 is attached to the toilet bowl 800. Thus, the deodorizing opening can be efficiently secured along the curved portion where the main body 400 slightly protrudes above the bowl 810. In addition, by providing the deodorizing air inlet 774 at the slight protrusion of the main body 400 in this way, for example, sewage scattered during cleaning such as “splash” of small water or “wet” by the nozzle is deodorized. Intrusion into the intake port 774 can be suppressed as much as possible. The deodorizing air intake 774 itself has a shape in which the front end force of the case plate 770 is also cut away to the rear, and the case plate 770 is attached to the toilet bowl 800, and a part of the deodorizing air intake 774 is covered with the toilet bowl. The part that actually inhales may have an elongated shape.

[0149] In addition, by making the curved concave surface 402 substantially vertical, it becomes easy to secure an air passage for air sucked through the deodorizing intake port 774. That is, as shown in FIG. 18, if the curved concave surface 402 is made vertical, the ventilation cross-sectional area of the exhaust duct 634 communicating with the deodorizing intake port 774 can be increased, and the pressure loss can be suppressed. As a result, the amount of deodorizing air can be secured and sufficient deodorizing performance can be obtained.

[0150] The structure of the main body 400 of the toilet device according to the present embodiment has been described in detail above.

Hereinafter, other features of the specific examples shown in FIGS. 1 and 2 will be described.

[0151] In the example shown in FIGS. 1 and 2, when the toilet lid 300 is opened, the main body 400 and the toilet seat 200 are almost completely exposed, and the user interferes with the toilet lid 300. You can sit in the toilet seat 200. Further, by supporting the toilet lid 300 at the rear portion of the main body 400, the user's ability to sit on the toilet seat 200 can also move the toilet lid 300 away. As a result, the user sitting on the toilet seat 200 is given a feeling of opening and a comfortable feeling of use is obtained. In addition, for example, even when a thick jacket or a long dress is rolled up and seated on the toilet seat 200, the jacket or one piece comes into contact with the toilet lid 300, which gives the user a feeling of pressure. And no hygienic discomfort.

On the other hand, when the toilet lid 300 is closed as shown in FIG. 2, not only the toilet seat 200 but also the main body 400 is almost completely covered by the toilet lid 300. In this way, if the toilet lid 300 covers almost the entire sanitary washing device, it is very smart, simple and clean. In addition, by covering the entire toilet apparatus with the toilet lid 300, dust, dust, etc. do not accumulate not only on the toilet seat 200 but also on the main body 400 when not in use. In addition, flights When the lid 300 is closed, there will be no “gap” or “unevenness” on the top surface of the toilet device, so the entire top surface of the toilet lid 300 should be wiped smoothly even when cleaning with a wet cloth. Can be cleaned.

[0153] In the case of this specific example, a stepped portion 405 is formed on the side surface of the main body 400. When the toilet lid 300 is closed, the step 405 is aligned with the rear lower end 305 of the toilet lid 300 in contact with or close to the rear end 305, and the side surface of the main body 400 and the side surface of the toilet lid 300 are substantially the same. Form a surface. As a result, when the toilet lid 300 is closed, a continuous flat surface from the toilet lid 300 to the main body 400 is also formed on the side of the toilet device, which further improves the appearance and prevents dust and dirt from accumulating. it can. In addition, even when the side surface of the toilet apparatus is wiped and cleaned with the toilet lid 300 closed, the wiper can be wiped smoothly and smoothly without the rag being pulled.

[0154] A recessed portion 410 is formed on the upper surface of the main body 400 of the sanitary washing device of the present embodiment, and the human body detection sensor 500 is provided there. On the other hand, a transmission window 310 is provided at the rear of the toilet lid 300.

The main body 400 human body detection sensor 500 is provided so that a part thereof is embedded in the recessed portion 410. As will be described in detail later, an infrared detection type sensor can be used as the human body detection sensor 500. For example, if a pyroelectric sensor is used, the presence of the user is increased! Can be detected with accuracy. In the case of a pyroelectric sensor, the movement of the heating element within a predetermined detection range in front of the pyroelectric sensor can be detected.

As shown in FIG. 4, in the state where the toilet lid 300 is closed, the human body detection sensor 500 detects the presence of the user in front of the sanitary washing device via the transparent window 310. That is, the transmission window 310 transmits infrared rays detected by the human body detection sensor 500. For example, when a pyroelectric sensor is used as the human body detection sensor 500, a far infrared ray having a wavelength of about 10 micrometers is detected. Therefore, the transmission window 310 also has a material force having a certain degree of transmittance with respect to infrared rays in this wavelength band. By using, for example, polyethylene as the material of the transmission window 310, the approach and presence of the user can be detected with high sensitivity through the transmission window 310 even when the toilet lid 300 is closed.

[0156] On the other hand, the toilet lid 300 that supports the transmission window 310 has a lower transmission rate than infrared transmission window 310 for infrared rays. It can be formed of a material having an excess rate. If the toilet lid 300 is made of a material that is harder and more durable than the transmission window 310, there will be less deflection and deformation, and there will be scratches. In addition, the color of the toilet lid 300 can be freely selected, and it is easy to match the color of the toilet bowl 800 and the main body 400. An example of a material for the toilet lid 300 that satisfies these requirements is polypropylene.

[0157] When the human body detection sensor 500 detects a user with the toilet lid 300 closed, the toilet lid 300 can be automatically opened by operating the electric opening / closing unit 780 built in the main body 400. In addition, for example, the toilet seat 200 can be heated quickly, the indoor heating unit provided in the main body 400 can be operated to warm the toilet, or a small amount of washing water can be poured into the toilet bowl 800 in advance to wet the bowl. It is possible to execute a process for suppressing adhesion.

[0158] Then, when the toilet lid 300 is opened as shown in Fig. 1, there is no shield in front of the human body detection sensor 500, so that the presence of the user can be detected as it is. The main body 400 is provided with a seating sensor 420 that can detect the presence of a user sitting on the toilet seat 200. As the seating sensor 420, for example, an infrared sensor that emits infrared rays and detects the amount of light by the amount of reflected light can be used.
