The main body has a drainage part for discharging wastewater generated in the sanitary washing function part to the bowl, a slender deodorizing intake port substantially along a contour line of the bowl, on a lower surface of the protruding part facing the bowl. A toilet device is provided.

  ADVANTAGE OF THE INVENTION According to this invention, the toilet apparatus provided with the sanitary washing | cleaning function part which can implement reliably deodorizing, drainage of waste water, etc., covering almost the bowl of a toilet bowl can be provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 are schematic perspective views showing the appearance of a toilet apparatus according to an embodiment of the present invention.
Moreover, FIG. 3 is the schematic diagram which removed the toilet seat 200 and the toilet lid 300 from this toilet apparatus, and was seen from diagonally upward.

  The toilet apparatus of the present embodiment includes a Western-style seat toilet 800 and a main body 400 provided at the upper rear side thereof. 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. This toilet device belongs to a so-called “water supply directly connected water supply type” and the like, and can supply water from the water supply to the toilet 800 without using a low tank and wash it. Inside the main body 400, a water supply control mechanism for controlling water supply from the water supply to the toilet bowl 800 is provided.

  On the other hand, the main body 400 also has a built-in mechanism for realizing a sanitary washing function. That is, the seating sensor 420 detects that the user is sitting on the toilet seat 200, and a water discharge nozzle (not shown) is advanced from the main body 400 into the bowl of the toilet bowl 800 according to the user's switch operation or the like. By spraying water from a spout provided near the tip, it is possible to wash the “buttock” of the user sitting on the toilet seat. In the present specification, “water” includes not only cold water but also heated hot water. 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 exhaust port 440 and an exhaust port 450 are appropriately provided on the side thereof. ing. The internal configuration of the main body 400 will be described in detail later.

And in this embodiment, as represented to FIG. 3, the main-body part 400 has the shape which retracted according to opening of the bowl 810 of the toilet bowl 800. FIG. That is, a curved concave surface 402 is provided on the front surface of the main body 400 substantially along the opening of the bowl 810.
FIG. 4 is a schematic diagram illustrating a toilet device of a comparative example. That is, this figure is also a perspective view showing a state in which the toilet seat and the toilet lid are removed from the toilet device.
In this comparative example, the main body 400 extends on the bowl 810 of the toilet bowl 800, and a region 400P indicated by a broken line is provided so as to block the rear of the opening of the bowl 810. However, when the main body 400 protrudes above the bowl 810 in this way, small water tends to be applied to the main body 400 when the male is standing up. Further, when the main body 400 protrudes above the bowl 810 in this way, the effective opening area of the bowl 810 is narrowed, so that a stenosis sensation is given to a man who uses it in a standing position. Further, the back surface side of the protruding area 400P is likely to be contaminated, and there is room for improvement in terms of cleanability. Furthermore, when the main body 400 protrudes above the bowl 810 as described above, even if dirt is attached to the rear upper part of the bowl 810, it is difficult to clean the portion.

  On the other hand, in the present embodiment, as shown in FIG. 3, the curved concave surface 402 is formed by retreating the front surface of the main body 400, so that it can be reduced even when used in a male standing position. It becomes difficult to get water. As will be described in detail later, in the present embodiment, the main body 400 has a protruding portion that protrudes from the end of the bowl 810 by several millimeters to several tens of millimeters. However, as can be seen from FIG. 402 is connected to the open end of the bowl 810 substantially continuously. For this reason, there is no visual stenosis for the user. And by retreating the main body 400 in this way, the adhesion of dirt can be suppressed, and the cleaning property can be remarkably improved.

  In the case of the prior art related to the toilet seat apparatus in which the main body portion does not protrude from the toilet opening, as described above with respect to the background art, the boundary portion between the main body portion and the bowl is completely exposed, so that the boundary portion is small. It becomes easy to splash water directly. Of course, it is conceivable that a packing is provided in the vicinity of the boundary so that small water does not enter the gap between the main body and the upper surface of the toilet bowl. May get in.

  On the other hand, in the toilet apparatus of the present embodiment, the front surface of the main body 400 has a curved concave surface 402, and the boundary between the main body 400 and the bowl 810 is always hidden by the main body 400. In the case of small use in the standing position, there is no visual stenosis, and small water is less likely to enter the gap between the main body 400 and the toilet bowl 800.

FIG. 5 is a schematic view of the toilet apparatus according to the present embodiment viewed obliquely from the front.
Moreover, FIG. 6 is the schematic diagram which looked at the toilet apparatus of the comparative example from the same angle as FIG.
That is, these figures represent a view of the bowl 810 from the perspective of the user cleaning the toilet while squatting in front of the toilet 800, specifically, about 100 millimeters away from the front end of the toilet 800, The appearance of the bowl 810 viewed from a height of about 1000 millimeters.

  Many Western-style toilet bowls are provided around the rim at the upper end of the bowl 810 so that the protrusion 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 protruding portion provided on the rim portion 820 can be easily cleaned with a rag or brush.

In the case of the comparative example shown in FIG. 6, even when the user squats in front of the toilet bowl 800, the rim portion 820 behind the bowl is hidden behind the protruding region 400P of the main body portion and cannot be seen. For this reason, in order for the user to clean the rim portion 820 below the region 400P, the user has to look into it in a bent posture.
On the other hand, in the toilet apparatus of the present embodiment, when the user squats in front of the toilet bowl 800, as shown in FIG. 5, the rim portion 820 at the rear end of the bowl 810 is also in the height direction from the lower end. The middle part is visible. For this reason, the dirt adhering to the rim portion 820 at the rear end of the bowl 810 can be easily seen, and cleaning with a rag or brush can be performed reliably and easily. That is, the cleaning property is remarkably improved.

FIG. 7 is a cross-sectional view of the toilet apparatus of the present embodiment.
Moreover, FIG. 8 is sectional drawing of the toilet apparatus of a comparative example.
That is, these drawings are schematic diagrams for explaining a range seen from the viewpoint of a user who cleans the toilet while squatting in front of the toilet 800. FIG.

  In the case of the comparative example shown in FIG. 8, it can be seen that the rim portion 820 at the rear end of the bowl 810 is hidden behind the protruding region 400 </ b> P of the main body 400 when viewed from the line of sight of the user squatting in front of the toilet bowl 800. . In addition, the back side of the protruding area 400P (the surface facing the bowl 810) is used for cleaning “bounce” from the sealed water of the bowl 810, and the “butt” of the user using a water discharge nozzle (not shown). Easily adheres to scattered sewage. Accordingly, it is also necessary to clean the back side of the protruding area 400P.

  On the other hand, according to this embodiment, as shown in FIG. 7, it can be seen up to the vicinity of the upper end of the rim portion 820 at the rear end of the bowl 810 as seen from the line of sight of the user squatting in front of the toilet bowl 800. Therefore, the user can clean and cleanly clean the back end of the bowl 810 using a rag or a brush in the posture, and confirm that the dirt has been removed and has been cleaned. Further, in the present embodiment, since the amount of protrusion of the main body 400 on the bowl 810 is suppressed, it is easy to clean dirt and the like attached to the back side of the protrusion. For example, even when cleaning with a rag or the like, the user can quickly wipe away from side to side with the rag applied to the back side of the main body 400.

  Further, the toilet bowl 800 of the present embodiment is provided with a toilet flush water introduction path 826 formed by a shelf 822 and an overhang 824 in the rim 820 at the upper edge of the bowl 810. By flowing the toilet flushing water along the toilet flushing water introduction path 826, the bowl 810 can be washed so that the toilet flushing water is spread over substantially the entire circumference of the bowl 810 to form a swirling flow. Since the upper edge of the bowl smoothly overhangs, the dirt can be easily wiped off, and the toilet bowl 800 can be cleaned very easily.

  Further, the curved concave surface 402 of the main body 400 can be a substantially vertical surface, and the front upper surface 400F connected thereto can be an inclined surface. By setting the curved concave surface 402 to be a vertical surface, even if small water or the like is applied, the small water quickly falls into the bowl 810 and there is no fear of scooping up the main body 400. Further, by curving and rounding the corner from the curved concave surface 402 to the front upper surface 400F, for example, when wiping with a rag or the like, it is possible to smoothly wipe and clean without wiping the rag or the like. Become.

FIG. 9 is a schematic plan view for explaining the protruding amount of the protruding portion of the main body 400 in the present embodiment.
As shown in the figure, the curved concave surface 402 of the main body portion maintains a form substantially along the opening shape of the bowl 810, and the entire curved concave surface 402 slightly protrudes from the bowl 810. If the protruding amounts to the bowl 810 at the left and right front ends of the curved concave surface 402 of this protruding portion are a and b, and the protruding amount to the bowl 810 near the center is c, a and b are relatively small, and c is It can be relatively large. If it does in this way, it will become easy to ensure the space (projection part) for drainage and deodorization, making it continue with the opening shape of bowl 810 substantially. Specifically, for example, a and b can be about several millimeters to about 10 millimeters, and c can be about 10 millimeters to about 10 millimeters. If the curved concave surface 402 is slightly protruded in this way, as will be described in detail later, drainage from the main body 400 to the bowl 810 can be ensured, and a deodorizing air inlet for the deodorizing function can be ensured.

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

  Next, the internal structure of the toilet device of this embodiment will be described.

FIG. 10 is a perspective view of the inside of the main body 400 viewed from the front.

  On the other hand, when the inside of the case cover 430 is viewed, a nozzle unit 610, a hot air drying unit 620, and a deodorizing unit 630 are provided in front of the case cover 430. The nozzle unit 610 has a water discharge nozzle that can freely move back and forth, and has a role of spraying water on a “butt” of a user sitting on the toilet seat 200 and washing it. The hot air drying unit 620 has a role of applying hot air to a “buttock” of a user sitting on the toilet seat 200 and drying it. The deodorizing unit 630 has a role of sucking air in the bowl 810 of the toilet bowl 800, deodorizing it, and discharging it from the exhaust port 440.

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

  An auxiliary operation unit 680 (see FIG. 11) is provided on the side surface of the case cover 430. The auxiliary operation unit 680 is provided with a switch for operating the “wet” cleaning by the nozzle unit 610. For example, the operation of the sanitary cleaning function can be controlled even when the operation by the remote controller (not shown) is impossible. It is what. A valve unit 690 is provided at the lower rear portion of the case cover 430. The valve unit 690 has a role of controlling 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 side by side on the upper 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 flush water that flows to the toilet 800. That is, the toilet device of this specific example has a so-called “water supply directly connected water supply” structure, and supplies water supplied from the water supply to the toilet bowl 800 via the toilet flush valve unit 730 without providing a low tank or the like. Perform cleaning.

  On the other hand, an indoor heating unit 740 is provided at the rearmost part of the case cover 430. The room warming unit 740 has a role of heating the toilet space in which the toilet apparatus is installed by discharging warm air from the discharge hole 450. In addition, a power cord is disposed at the lower end, and power such as AC 100 volts is supplied from the outside.

FIG. 12 is a perspective view for explaining the structure of the case plate 770.
FIG. 13 is a schematic view of the case plate 770 viewed from above.

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. The toilet flushing valve unit 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. As described above with reference to FIGS. 10 and 11, 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 773 is provided near the center of the front end of the case plate 770, and a deodorizing intake port 774 is opened on the right side thereof.
FIG. 14 is a schematic view of the central portion of the curved concave surface 402 of the main body 400 viewed from the front. FIG. 15 is an enlarged schematic view of the vicinity of the center.

  That is, 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, a closing for covering the hot air outlet and the hot air outlet. A hot air damper 470 is provided as a member. All of these are supported to be openable and closable, and are all closed in the standby state. Then, when the nozzle unit 610 advances to clean the “butt” of the user sitting on the toilet seat 200, the nozzle damper 460 opens. When the hot air is blown from the hot air drying unit 620 toward the user's “butt” or the like, the hot air damper 470 is opened.

  In order to prevent the small water from entering the inside of the main body 400 even when the nozzle damper 460 and the hot air damper 470 are closed, for example, when a small amount of water is used for men, for example, The gap S (see FIG. 15) with the case cover 430 is preferably 0.5 millimeters or less, for example.

  A drainage portion 773 is provided below the back side of the nozzle damper 460. FIG. 16 is an enlarged cross-sectional view of a portion of the drainage part 773. In the figure, the mechanism in the main body 400 is omitted for convenience.

  The drainage part 773 is formed in an extension part 770P in which the front end of the case plate 770 extends slightly downward. As can be seen from FIG. 14, the extending portion 770 </ b> P of the case plate 770 is gently curved with the nozzle damper 460 as the center. As can be seen from FIG. 15, the distal end of the drainage portion 773 has a converging shape that collects water at the center and discharges it downward. Thus, 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.

  For example, in the nozzle unit 610, when the nozzle advances or retracts, drainage occurs when water is sprayed onto the nozzle body to clean the body. The drainage part 773 has a role of discharging this drainage into the bowl 810. In addition to this, for example, before the nozzle advances or retreats, by spraying water from the outlet, the nozzle is prevented from being “clogged” or when the temperature of the outlet is stabilized. The drainage can be discharged from the drainage part 773 to the bowl 810. Furthermore, in the case where 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 773 to the bowl 810. Can be discharged reliably.

  On the other hand, according to the present embodiment, it is possible to suppress “climbing” of drainage to the back surface side of the drainage portion 773 (the side facing the toilet bowl 800 in 16). That is, if the drainage discharged from the drainage part 773 wraps around the back side of the case plate 770 as indicated by the arrow A in FIG. 16, 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.

  On the other hand, according to the present embodiment, the front end of the case plate 770 is extended downward to form the extended portion 770P, and the drainage portion 773 having a converging shape is provided at the front end, whereby the main body 400 As a result, the waste water generated inside can be surely dropped and drained into the bowl 810 to prevent the water from “scooping” to the back side.

Next, the deodorizing intake port will be described.
FIG. 17 is a schematic view of the case plate 770 viewed from the back side.
18 is a cross-sectional view taken along line AA in FIG.

  The deodorization intake port 774 is connected to the deodorization unit 630 and sucks 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 unit, for example, by the action of oxygen or ozone, the organic gas component contained in the intake air and causing odor is decomposed or adsorbed to remove the odor. 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 air inlet 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. By forming the deodorizing intake port 774 in such an elongated crescent shape, it is easy to ensure the intake opening area required for deodorization while minimizing the amount of protrusion of the main body 400 to the bowl 810. It becomes. That is, in the state where the main body 400 is mounted on the toilet bowl 800, the deodorizing opening can be efficiently ensured along the curved portion where the main body 400 slightly protrudes above the bowl 810. Further, by providing the deodorizing intake port 774 in 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 cut out from the front end of the case plate 770 toward the rear, and with the case plate 770 attached to the toilet bowl 800, a part of the deodorizing air intake 774 is covered with the toilet bowl, The part that actually inhales may be elongated.

  In addition, by making the curved concave surface 402 substantially vertical, it is easy to secure an air path for air sucked through the deodorizing intake port 774. That is, as can be seen from FIG. 18, when 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 pressure loss can be suppressed. As a result, a sufficient amount of deodorizing air can be secured and sufficient deodorizing performance can be obtained.

In the above, the structure of the main-body part 400 of the toilet apparatus of this embodiment was explained in full detail.
Hereinafter, other features of the specific examples shown in FIGS. 1 and 2 will be described.

  In the case of the specific 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 can access the toilet seat 200 without interfering with the toilet lid 300. I can sit down. Further, the toilet lid 300 can be moved away from the user sitting on the toilet seat 200 by pivotally supporting the toilet lid 300 at the rear portion of the main body 400. 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 dress is less likely to come into contact with the toilet lid 300. There is 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. Thus, if the toilet lid 300 covers almost the entire sanitary washing device, it is very smart, simple and clean. Further, by covering the entire toilet apparatus with the toilet lid 300, dust, dust, and the like do not accumulate on the main body 400 as well as the toilet seat 200 when not in use. Further, when the toilet lid 300 is closed, there is no “gap” or “unevenness” on the upper surface of the toilet apparatus, so that the entire upper surface of the toilet lid 300 can be smoothly and smoothly wiped with a wet cloth. It can be wiped and the cleaning property is improved.

  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 stepped portion 405 is aligned in contact with or close to the rear lower end 305 of the toilet lid 300, 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 plane extending from the toilet lid 300 to the main body 400 is also formed on the side surface 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, it can be wiped smoothly without being caught by a cloth.

And the recessed part 410 is formed in the upper surface of the main-body part 400 of the sanitary washing apparatus of this 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, when a pyroelectric sensor is used, the presence of the user can be detected with high accuracy. In the case of the pyroelectric sensor, the movement of the heating element within a predetermined detection range in front of the pyroelectric sensor can be detected.

  In the state where the toilet lid 300 is closed as shown in FIG. 4, the human body detection sensor 500 detects the presence of the user in front of the sanitary washing device through the transmission 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, far infrared rays having a wavelength of about 10 micrometers are detected. Accordingly, the transmission window 310 is made of a material 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 through the transmission window 310 with high sensitivity even when the toilet lid 300 is closed.

  On the other hand, the toilet lid 300 that supports the transmission window 310 can be formed of a material having a transmittance lower than that of the transmission window 310 for infrared rays. If the toilet lid 300 is made of a material that is harder and stronger than the transmission window 310, there is little deflection and deformation, and scratches are less likely to occur. Further, 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. Examples of the material of the toilet lid 300 that satisfies these requirements include polypropylene.
