Description

  The present invention relates to a sanitary washing device and a toilet device, and more specifically to a sanitary washing device for washing a user's “butt” or the like sitting on a sitting toilet with water and a toilet device provided with the same.

The sanitary washing device accommodates a water discharge nozzle for jetting washing water so that it can be moved forward and backward, and is attached to a seated toilet to wash a “butt” of a user sitting on a toilet seat. On the other hand, among toilet devices provided with a sitting toilet, there is a structure in which a vacuum breaker is provided in the middle of a water supply pipe. For example, in the case of a so-called “vacuum-type” toilet device, water and excrement in the toilet are sucked into a vacuum pipe and discharged. And the vacuum breaker is provided in the middle of the water supply piping of this toilet apparatus, and it is installed so that it may protrude above the upper end of a toilet bowl (for example, patent document 1). In addition to vacuum-type toilet devices, many flush-type toilet devices that allow water supplied from water to flow into the toilet without being stored in the low tank are vacuum breakers that protrude above the upper surface of the toilet. (For example, Patent Document 2).

FIG. 1 is a schematic perspective view of a toilet apparatus according to an embodiment of the present invention.
FIG. 2 is a schematic perspective view showing a state in which the sanitary washing device is removed from the toilet device.
Moreover, FIG. 3 is the schematic diagram which looked at the sanitary washing apparatus of this embodiment from diagonally backward. 2 and the subsequent drawings, the same reference numerals are given to the same elements as those shown in the above-mentioned drawings, and the detailed description will be omitted as appropriate.

  The toilet apparatus illustrated in FIGS. 1 to 3 is a toilet apparatus provided in an aircraft, for example. The bowl of the toilet bowl 600 is exposed at the opening of the concealment panel 500. And the sanitary washing apparatus 100 is attached to the upper back. The sanitary washing device 100 includes a main body 200 and a toilet seat 110 and a toilet lid 120 that are pivotally supported by the main body 200 so as to be rotatable. The main body 200 is provided with a water discharge nozzle 262 so that it can advance into the bowl of the toilet 600. The water discharge nozzle 262 sprays water from the tip of the water discharge nozzle 262 to wash the “butt” of the user sitting on the toilet seat 110. In the present specification, the term “water” includes not only cold water but also hot water.

  As shown in FIG. 2, a vacuum breaker 610 is provided behind the toilet bowl 600 so as to protrude upward from the concealment panel 500. As shown in FIG. 3, a storage recess 212 in which at least a part of the vacuum breaker 610 is stored is provided behind the bottom surface 202 of the main body 200 of the sanitary washing device 100 of the present embodiment.

Here, the structure of the concealment panel 500 and the toilet bowl 600 will be described in more detail.
FIG. 4 is a perspective view showing the concealment panel 500. The concealment panel 500 is a plate-shaped molded body, and is formed with an opening 510 from which a bowl surface of the toilet bowl is exposed and an opening 520 from which a vacuum breaker projects.

FIG. 5 is a perspective view illustrating a state where the concealment panel 500 and the toilet bowl 600 are separated.
FIG. 6 is a perspective view showing a state where the concealment panel 500 is attached to the toilet bowl 600. As shown in FIG. 5, a water supply pipe 620 is connected to the rear of the vacuum toilet 600, and a vacuum breaker 610 is provided in the middle thereof. The vacuum breaker 610 protrudes upward so that the upper end of the vacuum breaker 610 is higher than the upper surface of the toilet 600.
In a state where the toilet 600 is covered with the concealment panel 500, the vacuum breaker 610 protrudes from the opening 520 as shown in FIG.

FIG. 7 is a schematic view illustrating a state where the sanitary washing device 100 is attached.
The vacuum breaker 610 protruding from the concealment panel 500 is stored in the storage recess 212 provided on the bottom surface of the sanitary washing device 100 in a state where the sanitary washing device 100 is attached, and does not interfere with the sanitary washing device 100. Absent. Thus, by providing the storage recess 212 on the bottom surface of the sanitary washing device 100, the sanitary washing device 100 can be attached without interfering with the vacuum breaker 610.

  In the specific examples illustrated in FIGS. 3 and 7, the storage recess 212 is provided so as to be exposed on the back surface 204 together with the bottom surface 202 of the main body 200. In this way, it is not necessary to move the sanitary washing device 100 across the vacuum breaker 610 when the sanitary washing device 100 is attached to or removed from the toilet device. It is easy to work because it only needs to slide back and forth. Therefore, for example, even when the vacuum breaker 610 is inspected, the vacuum breaker 610 can be exposed by simply pulling the sanitary washing device 100 forward.

  FIG. 8 is a perspective view of the case plate 210 of the main body 200 of the sanitary washing device 100. That is, the main body 200 of the sanitary washing device 100 is configured by the case plate 210 and the case cover 290 (see FIG. 3). The case plate 210 has walls 222, 224, and 226 provided behind the case plate 210 so as to protrude toward the inside of the main body 200. With these walls 222, 224, and 226, a housing recess 212 is formed on the bottom surface of the main body 200. The walls 222, 224, and 226 separate the internal space of the main body 200 from the storage recess 212.

Among these walls, the front wall 222 and the left and right walls 224 prevent water and the atmosphere from entering the main body 200 from the housing recess 212 side. At the same time, the front wall 222 and the left and right walls 224 also prevent water and atmosphere from entering from the main body 200 side to the housing recess 212 side.
Further, the upper wall 226 suppresses intrusion of water and atmosphere from the housing recess 212 side into the main body 200.

  That is, by providing these walls 222, 224, and 226 to isolate the internal space of the main body 200 and the storage recess 212, water can enter the main body 200 even when water leaks from the vacuum breaker 610, for example. On the contrary, even if water leaks in the main body 200, the water can be prevented from leaking outside the toilet 600 such as around the vacuum breaker 610.

  A hole 223 is provided in the front wall 222. As will be described in detail later, the hole 223 is used to fix the nozzle unit and is liquid-tightly closed by packing or the like.

FIG. 9 is a schematic view illustrating elements accommodated in the main body 200.
Inside the main body 200, a controller 230, a hot water storage tank 240, a valve unit 250, a nozzle unit 260, and the like are provided. The controller 230, the hot water storage tank 240, the valve unit 250, and the like are water supply function units that supply water to the nozzle unit 260. Here, the controller 230 and the hot water storage tank 240 are arranged on both sides of the storage recess 212. The nozzle unit 260 is provided from the front to the top of the storage recess 212. Here, an electrical wiring (not shown) may be connected between the controller 230 and the hot water storage tank 240. In this case, when a wiring fastener is attached to the wall 226 on the upper surface of the storage recess 212 and the electrical wiring between the controller 230 and the hot water storage tank 240 is fixed by this wiring fastener, the electrical wiring may fluctuate due to vibration or the water discharge nozzle 262 Can be reliably and easily prevented.

FIG. 10 is a cross-sectional view of the main body 200.
The vacuum breaker 610 protruding upward is stored in the storage recess 212. And the nozzle unit 260 is provided adjacent to the wall 222 provided in front thereof. The nozzle unit 260 includes a mounting base 264 and a water discharge nozzle 262 in an inclined posture supported by the mounting base 264 so as to be slidable. The upper end of the rear portion of the nozzle unit 260 is located above the upper wall 226 that forms the storage recess 212. That is, by providing the rear end of the nozzle unit 260 upward, interference between the nozzle unit 260 and the storage recess 212 can be prevented.

FIG. 11 is a schematic view of the mounting base 264 as viewed from above.
The mounting base 264 has a pair of mounting holes 265 provided on the left and right sides thereof. The mounting base 264 is fixed to the case plate 210 with screws or the like through the pair of mounting holes 265. By fixing with the pair of mounting holes 265, the mounting base 264 can be more securely fixed to the case plate 210.

Furthermore, in the present embodiment, the mounting base 264 is also fixed to the wall 222 of the case plate 210.
FIG. 12A is a schematic diagram in which a fixing portion of the mounting base 264 is enlarged, and FIG. 12B is a partially enlarged sectional view thereof.
The mounting base 264 has a protrusion 266 that protrudes rearward at the upper portion thereof. The protrusion 266 is inserted into a hole 223 provided in the wall 222 via a packing 270 and fixed. The packing 270 is made of an elastic body such as rubber or foam material. By inserting the packing 270 between the protrusion 266 and the hole 223 in a crushed state, the gap can be filled and the insertion portion can be supported mechanically firmly and liquid tightly.

  According to the present embodiment, the nozzle unit 260 is mechanically firmly fixed by fixing the mounting base 264 to the case plate 210 in the pair of mounting holes 265 and simultaneously fixing the protrusion 266 to the hole 223 at the rear thereof. can do. As can be seen from FIG. 10, in this embodiment, a storage recess 212 is provided on the bottom surface of the case plate 210 in order to store the vacuum breaker 610. For this reason, the inclination angle of the nozzle 262 increases. That is, when the storage recess 212 is provided, the height behind the nozzle 262 (the side closer to the vacuum breaker 610) needs to be higher than when the storage recess 212 is not provided. As a result, the height of the nozzle unit 260 becomes higher and the position of the center of gravity also becomes higher.

  However, when the center of gravity of the nozzle unit 260 is increased, the upper side is likely to be unstable as viewed from the case plate 210. In other words, when the mounting base 264 is fixed only to the case plate 210, the upper part of the mounting base 264 is likely to fluctuate from side to side or from front to back. If the nozzle unit fluctuates, the direction of water discharge will be blurred and the cleaning effect will be reduced, and the wiring and piping connected to the nozzle unit 260 will be disconnected, and interference with the wiring and piping provided around the nozzle unit 260 will occur. In addition, mechanical stress may concentrate on the mounting portion of the mounting base, resulting in damage. In particular, in the case of an aircraft, a train, and the like, since shaking and vibration are larger than those in a normal building, wobbling due to an increase in the center of gravity of the nozzle unit 260 is easily amplified.

  On the other hand, according to this embodiment, the protrusion 266 is provided at the upper rear side of the mounting base, and is inserted and fixed to the hole 223 provided in the wall 222 via the packing 270, whereby the upper fluctuation of the nozzle unit 260 is prevented. It can be greatly reduced. As a result, even when installed in an environment with large vibrations or vibrations such as airplanes or trains, sanitary washing equipment that suppresses shaking in the water discharge direction and damages the mounting part, operates stably and has excellent reliability. Can provide.

  Although FIG. 12 shows a specific example in which the protrusion 266 is inserted and fixed into the hole 223 via the packing 270, the present invention is not limited to this. In addition, for example, a similar effect can be obtained by screwing a part of the mounting base 264 to the wall 222 or fixing it with other means, and these various modifications are also included in the scope of the present invention. Is done.

FIG. 13 is a schematic diagram illustrating the internal structure of a sanitary washing device according to a modification of the present embodiment.
In this modified example, a multi-stage water discharge nozzle 268 is provided in an inclined posture with the water discharge hole side as a lower position. That is, the water discharge nozzle 268 has two or more stages of movable parts, and the total length of the advanced nozzle is longer than the total length of the stored nozzle.
FIG. 14 is a schematic diagram illustrating an example of a multi-stage water discharge nozzle. That is, FIG. 14 shows a three-stage water discharge nozzle, FIG. 14 (a) shows the housed state, and FIG. 14 (b) shows the advanced state.

  In the case of this specific example, the water discharge nozzle 268 includes a first cylindrical body 268A, a second cylindrical body 268B supported so as to be slidable thereto, and a third cylindrical body slidably supported thereto. It has a cylindrical body 268C and a fourth cylindrical body 268D that is slidably supported on the cylindrical body 268C. A water discharge hole 261 is provided near the tip of the fourth cylinder 268D. Further, a nozzle cleaning chamber 269 is provided at the tip of the mounting base 264 so that the periphery of the water discharge nozzle 268 and the like can be cleaned.

By providing such a multistage water discharge nozzle, the total length in the housed state (the state shown in FIGS. 13 and 14A) can be made shorter than that in the advanced state (the state shown in FIG. 14B). As a result, the main body 200 can be incorporated without interfering with the housing recess 212. That is, even when the storage recess 212 is provided, the nozzle unit 260 that does not extend to the upper side of the storage recess 212 and can be stored compactly only in front of the storage recess 212 can be realized.
In FIG. 14, a three-stage water discharge nozzle is illustrated, but the present invention is not limited to this, and a multi-stage water discharge nozzle having a movable part with two or more stages can be used as appropriate. .

FIG. 15 is a schematic diagram showing the internal structure of a sanitary washing device according to another modification of the present embodiment.
In this modified example, two water discharge nozzles 262A and 262B are provided in the main body 200 in an inclined posture with the water discharge hole side as a lower position. These water discharge nozzles 262 </ b> A and 262 </ b> B are arranged so that the front approaches the center of the case plate 210, and the rear is separated into the left and right sides of the side walls 224 and 224 constituting the storage recess 212. That is, when viewed from above, these water discharge nozzles 262A, 262B are arranged so as to be inclined so that the rear escapes the storage recess 212 to the left and right. In this way, as described above with reference to FIG. 10, it is not necessary to extend the rear end of the water discharge nozzle above the wall 226 on the upper surface of the storage recess 212.

  That is, instead of extending the rear end of the water discharge nozzle above the storage recess 212, it can be stored in the main body 200 compactly by extending to the side of the storage recess 212. Although FIG. 15 shows a specific example in which two water discharge nozzles 262A and 262B are provided, the present invention is not limited to this, and only one of these water discharge nozzles may be provided. When two water discharge nozzles are provided, for example, one of them can be used for “wet” cleaning, and the other can be used for “bidet” cleaning.

FIG. 16 is a schematic diagram showing the internal structure of a sanitary washing device according to still another modification of the present embodiment.
In this modified example, the water discharge nozzle 262 is not provided in the main body portion 200 but is provided in the vicinity of the front end of the toilet seat 110 instead. The main body 200 is provided with a hot water storage tank 240, a water supply mechanism 250, and the like, and water is supplied to the water discharge nozzle 262 via a pipe (not shown).

  In this way, the storage recess 212 provided in the main body 200 and the water discharge nozzle 262 do not interfere with each other. Accordingly, the storage recess 212 is provided, and the main body 200 can be made compact, and water can be discharged from the front end of the toilet seat 110 by the water discharge nozzle 262 to wash the user's “buttock” and the like.

The embodiments of the present invention have been described above with reference to specific examples. However, the present invention is not limited to these specific examples. For example, the characteristics of the specific examples described above with reference to FIGS. 1 to 16 can be appropriately combined within the technically possible range, and these are also included in the scope of the present invention.
Further, the structure of the sanitary washing device and the content of its operation are not limited to those described above with reference to FIGS. 1 to 16, and those skilled in the art can implement the present invention in the same manner by appropriately modifying the design. What can obtain an effect is also included in the scope of the present invention as long as it includes the gist of the present invention. For example, the water discharge nozzle may advance or retreat by power such as a motor, or may advance or retreat by water pressure.
In addition, the present invention is not limited to a vacuum toilet device, and can be similarly applied to flush toilet devices having various structures to obtain the same operational effects.

  8 and the like show a specific example in which the housing recess 212 is formed in the case plate 210. However, the present invention is not limited to this, and a wall (for example, the wall 222) for forming the housing recess 212 is shown. 224, 226, etc.) may be provided on the case cover 290 side. That is, the housing recess 212 may be completed by combining the case plate 210 and the case cover 290. Furthermore, a member provided with a wall (for example, walls 222, 224, 226) for forming the storage recess 212 is provided as a separate member, and the case plate 210, the case cover 290, and this separate member are combined. Accordingly, the storage recess 212 may be formed.

  Further, in FIG. 10 and the like, a specific example in which almost the entire protrusion of the vacuum breaker 610 is stored in the storage recess 212 is shown, but the present invention is not limited to this, and the protrusion of the vacuum breaker 610 is not limited to this. It suffices that at least a part is stored in the storage recess 212.

  Moreover, the form of the water discharge nozzle is not limited to a linear shape. For example, by providing a water discharge nozzle that is curved or warped upward or left and right, it is possible to prevent the interference with the storage recess 212 and store the compact in the main body 200.

  3, FIG. 7 to FIG. 12 and the like show specific examples in which the housing recess 212 is exposed also on the back surface 204 of the main body 200 of the sanitary washing device 100, but the present invention is not limited to this. .
