Description

  The present invention relates to a sanitary washing device used by being attached to a Western-style toilet.

  In recent years, Western-style toilets have become more multifunctional, and a sanitary washing device having a sanitary washing mechanism after defecation or an opening / closing mechanism of a toilet seat or toilet lid is attached to the rear part of the upper surface of the toilet bowl. Since such a sanitary washing device needs to advance the sanitary washing nozzle toward the bowl portion of the toilet bowl, the rear member of the toilet bowl is usually in a state where a part of the bottom member covers the bowl portion of the toilet bowl. Is attached.

  FIG. 13 is a perspective view showing a lower surface portion of a bottom surface member of a conventional sanitary washing device, but the bottom surface member 90 is installed on the toilet bowl in a state where the inner edge of the bowl portion is located along a two-dot chain line 95 in the drawing. Is done. Although the bottom member 90 is formed in a substantially flat plate shape, an ABS resin having high dimensional accuracy and high rigidity is usually used because of providing bosses and ribs for attaching various parts of the sanitary washing device. The top cover, toilet seat and toilet lid are made of PP resin with excellent chemical resistance and good appearance. The ABS resin has a property that its surface energy is higher than that of PP resin, and dirt is more likely to adhere than PP resin.

  A drain hole 92 for waste water from the inlet / outlet 91 of the nozzle 96 and the internal mechanism of the sanitary washing device is provided in a portion near the front edge of the bottom surface member 90. Further, in order to prevent water coming out of the entrance / exit 91 and the drainage hole 92 from entering between the bottom member 90 and the toilet bowl, it protrudes around the entrance / exit 91 and the drainage hole 92 toward the bowl portion of the toilet bowl. Ribs 93 and 94 are formed. For this reason, the part which covers the bowl part of the toilet bowl of the bottom member 90 of the sanitary washing apparatus has a shape with many corners (corners).

  When a Western-style toilet with a sanitary washing device is used, a part of the lower surface portion of the bottom member 90 (two-dot chain line 95) where dirty water or urine produced by reflection of sanitary washing water on the human body faces the bowl portion. However, the bottom surface is often unnoticeable, causing odors. In this case, dirt adhering to the flat surface portion of the bottom member 90 can be wiped off with a rag or the like, but in particular, a corner portion formed at the base end portion of the ribs 93 and 94 around the inlet / outlet 91 of the nozzle 96 and the drain hole 92 ( The dirt adhering to the (corner) cannot be removed even if it is wiped and cleaned later, so that it cannot be removed, which is one of the major causes of bad odor. Furthermore, the bottom member made of ABS resin has a high surface energy, and as time passes, it becomes a sticky stain, which further promotes the generation of bad odor.

  Then, in order to be able to clean a bottom face member, what made it possible to remove the bottom face member (detachable panel) located in the part which covers a bowl part is proposed (for example, refer to patent documents 1). ). In this sanitary washing device, when cleaning is required, the detachable panel can be removed, and so-called round washing can be performed to remove dirt. Moreover, what was provided with the raising / lowering mechanism for lifting a sanitary washing apparatus from a toilet bowl is proposed (for example, refer patent document 2). In this case, if a part of the sanitary washing device is lifted from the toilet using the lifting mechanism, the gap between the toilet and the sanitary washing device widens, so that the user can insert a hand or the like to easily wipe the bottom surface of the bottom member. be able to.

  In the case of the sanitary washing device described in Patent Document 1, since it is necessary to remove the detachable panel every time cleaning is performed, the work becomes complicated, and there is a possibility that the parts may be damaged while the detachable panel is frequently detached and attached. is there.

  On the other hand, in the case of the toilet device (Western style flush toilet) described in Patent Document 2, a lifting mechanism that is not directly related to the cleaning function used in the stool operation is incorporated, so that the structure is complicated and the device The moving part tends to cause a failure or a decrease in durability. In addition, since the apparatus must be lifted every time it is cleaned, handling is complicated, and the lifting operation itself may be a physical burden for a person with weak power or a handicapped person.

  Furthermore, in any of the prior arts described in Patent Documents 1 and 2, dirt stuck to the inlet / outlet of the nozzle and the ribs around the drainage hole cannot be easily removed by wiping and cleaning. The fact is that it is not possible to sufficiently remove the essential dirt for the troublesome work such as raising and lowering the cleaning device.

  The problem to be solved by the present invention is to provide a sanitary washing device having a simple structure and capable of easily removing dirt adhered to the bottom member of the sanitary washing device covering the bowl portion of the toilet bowl by wiping and cleaning. is there.

In addition, the direction represented by the words “front” and “rear” in the present application refers to a direction based on a user seated in a toilet posture on a Western-style toilet.

  With such a configuration, the portion of the bottom surface member of the sanitary washing device that covers the bowl portion of the Western-style toilet bowl swells toward the bowl portion side, so that it can be easily wiped and cleaned with a simple structure. It becomes possible, and attached dirt can be easily removed.

On the other hand, the sanitary washing device of the present invention is a sanitary washing device provided with a nozzle for sanitary washing and installed on the western-style toilet with a part of the bottom member covering the rear part of the bowl portion of the western-style toilet. A region of the bottom member facing the bowl portion is formed by a bulging surface that protrudes toward the bowl portion side, and an inlet / outlet of the nozzle is provided on the bulging surface, and the bowl portion of the Western-style toilet bowl is partially formed on the bulging surface An opening for deodorizing the odor is provided, and a continuous convex-shaped deodorizing filter is arranged so as to be able to be pulled out so as not to cause a step with the convex surface formed by the bulging surface in the opening . With such a configuration, a continuous convex surface having no step is formed by the bulging surface and the deodorizing filter, so that dirt is less likely to adhere and wiping and cleaning becomes easy. Further, since the deodorizing filter can be taken in and out, only the deodorizing filter can be removed from the opening of the bulging surface and carefully cleaned.

Further, the sanitary washing device of the present invention is a sanitary washing device provided with a nozzle for sanitary washing and installed on the western-style toilet with a part of the bottom member covering the rear part of the bowl portion of the western-style toilet. A region of the bottom member facing the bowl portion is formed by a bulging surface protruding toward the bowl portion side, and an inlet / outlet of the nozzle is provided on the bulging surface, and the bulging surface is located on the front side of the Western-style toilet It has a front surface portion and a rear surface portion located on the rear side of the Western-style toilet, and has an opening for drainage in a part near the boundary between the front surface portion and the rear surface portion . With such a configuration, since the opening is located near the lowermost part of the bulging surface, the drainage discharged from the opening does not fall along the bulging surface, and prevents dirt from adhering to the bulging surface. be able to.

  According to the present invention, it is possible to easily remove the dirt attached to the bottom member of the sanitary washing device that covers the bowl portion of the Western-style toilet by wiping and cleaning.

  Hereinafter, a sanitary washing apparatus according to an embodiment of the present invention will be described with reference to the drawings. 1 is a perspective view showing a sanitary washing apparatus according to an embodiment of the present invention with a toilet seat and toilet lid removed, FIG. 2 is a plan view of the sanitary washing apparatus, and FIG. 3 is a cross-sectional view taken along line AA in FIG. FIG. 4, FIG. 4 is a sectional view taken along line BB in FIG. 2, FIG. 5 is a partial perspective view seen from the direction of arrow C in FIG. 7 is a partially enlarged view of FIG. 6, FIG. 8 is a sectional view taken along the line DD in FIG. 7, and FIG. 9 is a partially omitted view showing the vertical sectional shape of the bulging surface shown in FIG.

  As shown in FIGS. 1 to 4, in the sanitary washing device 10 of the present embodiment, a top cover 10 a made of PP resin is provided above the bottom member 2 made of ABS resin, and a western type is provided inside the sanitary washing device 10 main body. A sanitary washing nozzle 1 that enters and exits the bowl portion 4 of the toilet bowl 3 is provided, and a part of the bottom member 2 covers the rear portion of the bowl section 4 of the western toilet bowl 3 so that the upper edge 3a of the western toilet bowl 3 is Installed at the rear. The bottom surface member 2 is an injection molded product of ABS resin, and is formed in a substantially planar shape, but a corner portion (corner portion) that protrudes toward the bowl portion 4 side in an area facing the bowl portion 4 of the bottom surface member 2. It is formed as a bulging surface 5 having no surface. An entrance / exit 6 of the nozzle 1 is provided in a part of the bulging surface 5.

  As shown in FIG. 5 to FIG. 7, the bulging surface 5 is formed by a continuous curved surface composed of a front surface portion 5 f located on the front side and a rear surface portion 5 r located on the rear side, and the center of the front surface portion 5 f. Is provided at the inlet / outlet 6 of the nozzle 1. The rear surface portion 5r is formed of a curved surface that is smoothly continuous from the surface 2a that overlaps the rear portion of the upper edge 3a of the western toilet 3 in the bottom surface member 2, and the surface 2a that overlaps the rear portion of the upper edge 3a has an upper edge 3a. A packing 7 is disposed between the bottom member 2 and the bottom member 2.

  Also, a part of the bulging surface 5 is provided with a deodorizing opening 8 for sucking the odor of the bowl portion 4 of the Western-style toilet 3, and the opening 8 has a bulging surface 5 as shown in FIG. A convex-shaped deodorizing filter 9 that forms a convex surface that is continuous with the curved surface is arranged so as to be able to be pulled forward and detachable. Further, an opening 11 for drainage is provided in the vicinity of the ridge line portion 5m that forms the boundary between the front surface portion 5f and the rear surface portion 5r of the bulging surface 5. In the present embodiment, the deodorizing opening 8 is disposed on the left side and the drainage opening 11 is disposed on the right side with the doorway 6 interposed therebetween.

  The usage and cleaning function of the sanitary washing device 10 are the same as those of the conventional sanitary washing device, but the bulging surface 5 formed on the lower surface portion of the bottom member 2 is a corner protruding toward the bowl 4 side of the western toilet 3. Since it has a shape without a portion (corner), it can be easily wiped with a simple structure, and attached dirt can be easily removed.

  Further, by forming the bulging surface 5 with a continuous curved surface, it has a smooth shape without stepped portions, corner edge portions, etc. existing in the bottom surface member 90 of the conventional sanitary washing apparatus shown in FIG. Therefore, wiping and cleaning is extremely easy. Therefore, the situation where sewage or urine after being subjected to sanitary washing adheres to the bulging surface 5 and becomes sticky dirt does not occur. Moreover, since the dirt adhering to the upper surface cover 10a and the toilet seat / toilet lid is easy to notice that the dirt adheres and is made of PP resin, the dirt can be removed very easily by wiping and cleaning immediately. Furthermore, since the packing 7 is disposed in alignment with the edge of the bowl portion 4, the sewage does not enter between the bottom member 2 and the upper edge 3 a of the western toilet 3. That is, the toilet device in which the sanitary washing device 10 of the present embodiment is attached to the western toilet 3 can almost eliminate the cause of the generation of odor.

  Furthermore, as shown in FIG. 9, the front surface portion 5f located on the front side of the bulging surface 5 has an inclination angle R of 40 degrees, and the front and rear ports 6 of the nozzle 1 are provided in the front surface portion 5f. For this reason, when the user looks at the bowl portion 4 in a natural standing posture in front of the Western-style toilet 3, the front surface portion 5f of the bulging surface 5 has an angle that is difficult to see, and sewage and the like attached to the front surface portion 5f are visually recognized. Because it becomes difficult, it does not give the user an unsanitary feeling. Moreover, since the entrance / exit 6 is opened to the lowest end of the bulging surface 5, the overflow water generated in the sanitary washing device 10 does not accumulate on the upper surface side of the bulging surface 5, and the bowl portion 4 extends from the entrance / exit 6. To be discharged.

  If the inclination angle R of the front surface portion 5f exceeds 45 degrees, the front surface portion 5f of the bulging surface 5 can be seen with the user standing in front of the western-style toilet 3, and if the inclination angle R becomes smaller than 30 degrees. This is not preferable because a part of the stored nozzle 1 is exposed from the entrance / exit 6.

  On the other hand, the rear surface portion 5r located behind the bulging surface 5 is composed of a curved surface having no irregularities that is continuous from the surface 2a of the bottom surface member 2 that overlaps the rear portion of the upper edge 3a of the western-style toilet 3, so cleaning is necessary. Then, the lower surface of the bottom surface member 2 covered on the bowl portion 4 can be easily cleaned only by wiping along the rear surface portion 5r which is a curved surface. Further, the rear surface portion 5r of the bulging surface 5 is curved so that the inclination gradually becomes steep so that the maximum inclination angle does not exceed 45 degrees from the surface 2a overlapping the rear portion of the upper edge 3a of the western toilet 3 to the front. Therefore, even on the Western-style toilet bowl 3 made of earthenware that easily causes a dimensional difference for each product, it can be installed without causing any trouble due to the dimensional difference.

  Further, since the inclination of the rear surface portion 5r of the bulging surface 5 is set to 45 degrees or less, a finger insertion portion 21 that allows insertion of fingers is formed between the bulging surface 5 and the upper side surface of the bowl portion 4. Wiping and cleaning can be easily performed by inserting a finger up to the back side of the member 2 along the edge of the bowl portion 4, and attached dirt can be easily removed.

  Further, the curved surface forming the rear surface portion 5r of the bulging surface 5 has an inflection point (corner portion) S1 that starts to bend from the surface 2a that overlaps the rear portion of the upper edge 3a of the western toilet 3 and an inflection point (corner portion) of the rear surface portion 5r. ) The corners are eliminated by making S2 curved surfaces each having a curvature radius of about 5 mm to 10 mm. When the curvature radius of these inflection points S1 and S2 is set to 5 mm or more, the fibers of the rag can enter the inflection points S1 and S2, so that the dirt attached to these portions can be wiped off. In the present embodiment, the ridge line portion 5m that forms the boundary between the front surface portion 5f and the rear surface portion 5r of the bulging surface 5 is also formed to have a curved surface with a curvature radius of about 5 mm to 10 mm.

  Here, FIG. 10 is a perspective view showing the bottom member 2 constituting the sanitary washing device 10 shown in FIG. As described above, when the sanitary washing device 10 is installed on the western toilet 3, the packing 7 is sandwiched between the upper edge 3a rear portion of the western toilet 3 and the bottom member 2 of the sanitary washing device 10 (see FIG. 9). ). As shown in FIGS. 2 and 10, the packing 7 includes a central portion 7a arranged in a curved shape along the circular arc portion 3r at the rear of the upper edge 3a of the western-style toilet 3, and the left and right extending from the central portion 7a. It is formed with an end portion 7b that is provided and arranged in a straight line along the front edge portion 2f of the bottom surface member 2, and is adhered to the bottom surface member 2 with a double-sided tape or the like. The central portion 7a of the packing 7 has a function of preventing sewage such as urine from entering the gap between the bottom member 2 and the upper edge 3a of the western toilet 3 from the bowl portion 4, and the left and right end portions 7b are It has a function of preventing sewage and the like on the surface of the upper edge 3a from entering the gap.

As shown in FIG. 11, an opening 8 for deodorization is provided in a part of the bulging surface 5, and a convex-shaped deodorizing filter 9 that forms a convex surface continuous with the bulging surface 5 in an adapter 20 provided in the opening 8. Is detachable and detachable. Thereby, since the continuous convex surface without a corner | angular part (corner part) is formed with the bulging surface 5 and the deodorizing filter 9 (refer FIG. 5, FIG. 8), a stain | pollution | contamination does not adhere easily and wiping cleaning is also easy.

  Further, since the deodorizing filter 9 is detachable, only the deodorizing filter 9 can be removed from the opening 8 of the bulging surface 5 and carefully cleaned as shown in FIG. Since the front edge portion of the deodorizing filter 9 is provided with an attaching / detaching knob 9a protruding in a tongue shape, the attaching / detaching operation can be easily performed by holding the knob 9a with a fingertip. Furthermore, the deodorizing filter 9 has a substantially triangular shape in plan view, and a receiving portion matching the planar shape is formed on the bottom surface member 2, so that the deodorizing filter 9 can be inserted in the direction shown in FIG. Cannot be plugged in. As described above, since the erroneous installation of the deodorizing filter 9 is prevented, there is no step between the bulging surface 5 and the deodorizing filter 9 when the deodorizing filter 9 is mounted, and a rag is caught during wiping and cleaning. No dirt remains on the steps.

  Next, with reference to FIG. 12, the drainage opening 11 (see FIG. 5) provided in a part of the bulging surface 5 will be described. FIG. 12 is a perspective view showing the internal structure of the sanitary washing apparatus 10 shown in FIG.
