Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a sanitary washing apparatus that jets washing water to a local part of a human body seated on a toilet seat to wash the local part.
[0002]
[Prior art]
  In this type of sanitary washing apparatus, generally, washing water for anal washing and washing water for female local washing can be ejected. And the form (single nozzle form) in which multiple flow paths for anal washing and female local washing are formed on a single nozzle, or multiple nozzles for anal washing and female local washing are arranged in parallel An installed configuration (multiple nozzle configuration) has been proposed.
[0003]
[Problems to be solved by the invention]
  In the single nozzle form, since there is a single nozzle, there is an advantage that it is possible to reduce the size of the nozzle device including the nozzle, and thus the sanitary washing device as a whole. By the way, in recent years, it has been demanded to increase the functionality so that local cleaning with different cleaning feelings such as hardware and software can be executed. For this purpose, it is necessary to prepare a flow path for hard feeling and soft feeling separately for anal washing and female local washing. However, since the number of flow paths that can be formed in a single nozzle is limited in a single nozzle, the cleaning function for anal cleaning and female local cleaning was lacking in functionality.
[0004]
  Further, in the single nozzle form, the washing water spouted at the time of anal washing bounces back to the nozzle, and this bounce washing water adheres to the periphery of the female local washing spout. The dirt due to the adhering and splashing washing water is removed by so-called self-cleaning in which washing water is applied to the periphery of the jet outlet prior to the local washing. However, even if this self-cleaning is carried out carefully, there is no change in the fact that the wash water is ejected from the spout at which the rebound wash water adheres at the time of anal washing. Therefore, there was a risk that this woman may have anxiety that she lacks hygiene due to the irrigation of the washing water in a very delicate place such as a female local area.
[0005]
  On the other hand, in the multi-nozzle form, it is possible to achieve multiple functions of the cleaning function for anal cleaning and female local cleaning by forming a flow path at each nozzle of the anal cleaning nozzle and the female local cleaning nozzle. Further, when the female local cleaning nozzle is positioned in the sanitary cleaning device main body at the time of anal cleaning, the bounce cleaning water at the time of anal cleaning is relatively not attached to the nozzle outlet. In other words, the above-described problem in the single nozzle form can be solved to some extent by adopting the multiple nozzle form. However, since a plurality of nozzles are merely installed in parallel, miniaturization is hindered. Further, in the multiple nozzle form, a drive system for moving the nozzle to the cleaning position at the time of cleaning is required for each nozzle, so that the size of the nozzle device including the driving source is not sufficient. Note that, for example, even if an anal cleaning nozzle for hard feeling and an anal cleaning nozzle for soft feeling are installed in parallel for the purpose of only anal cleaning, there is no change in the problem of miniaturization.
[0006]
  Washing of women's local area is to wash away bleeding and tissue waste during menstruation with erupted wash water and keep the female area clean, but there is a risk of anxiety about this cleanliness for the following reasons. there were. During menstruation, the amount of bleeding and tissue waste is not uniform and varies from person to person, and may vary from person to person. This bleeding and tissue waste may adhere to the epidermis in the region beyond the female local area. When such a situation is reached, there is a fear that anxiety that cleaning is insufficient and cleanliness is lacking simply by spraying washing water on the female local area. Although it has been proposed that the range of spray water to be washed can be changed at the time of female local cleaning, this can only deal with individual differences in the female local area, up to the skin area beyond the female local area. It was not intended for cleaning.
[0007]
  The present invention has been made to solve the above-described problems, and an object thereof is to eliminate anxiety about downsizing of an apparatus and cleaning of a female local area while including a plurality of nozzles.
[0008]
[Means for solving the problems and their functions and effects]
  In order to solve at least some of these issues,Akira no MaeThe raw cleaning apparatus has the following configuration. That is,
  A sanitary washing device for washing a local part of a human body seated on a toilet seat,
  Having first and second nozzles for jetting cleaning water in the local area;
The first nozzle includes a flush water outlet and an in-nozzle passage leading to the outlet, and the wash water is ejected from the outlet through the in-nozzle passage;
  The second nozzle isA flush water outlet and an in-nozzle passage leading to the outlet, and the washing water is ejected from the outlet through the in-nozzle passage.A storage portion shaped like the outer periphery of the first nozzle so as to store the first nozzle;
  It is characterized by that.
[0009]
  In the 1st sanitary washing apparatus of this invention which has the said structure, a 1st nozzle is accommodated in the accommodating part of a 2nd nozzle, and a 1st, 2nd nozzle is integrated. In addition, the storage portion is shaped to follow the outer peripheral shape of the first nozzle, and space waste during nozzle storage can be eliminated. Therefore, it is possible to reduce the size of the conventional unit in which a plurality of nozzles are simply arranged in parallel by the amount integrated in this way. Further, in a state where the first nozzle is housed in the second nozzle, it looks more like a single nozzle than a plurality of nozzles and can be handled like a single nozzle, so that the appearance is improved and the handling becomes easy.
[0010]
  This departureAkira no MaeThe raw washing apparatus can also take the following aspects. The first aspect is
  The first and second nozzles are provided so that they can be individually advanced and retracted between a standby position for cleaning standby and a cleaning position for local cleaning,
  The said accommodating part shall be a guide part at the time of said 1st nozzle advancing / retreating.
  If it carries out like this, a 1st nozzle can be guided by the storage part of a 2nd nozzle, and can be advanced / retreated easily.
[0011]
  In these cases, the first and second nozzles can be arranged so that their axial centers are concentric, or can be arranged so that their axial centers are decentered vertically. By doing this, it is possible to further improve the appearance by omitting space waste during nozzle storage.
[0012]
  In addition, one of the first and second nozzles moves back and forth between the first cleaning position for anal cleaning and the standby position,
  The other nozzle of the first and second nozzles advances and retreats between a second cleaning position for female local cleaning, which is a position in front of the first cleaning position, and the standby position. be able to.
  In this way, the other nozzle can be positioned at the standby position at the time of anus cleaning, and it is possible to effectively avoid the splashing cleaning water from being applied to the other nozzle at the time of anus cleaning. Therefore, in addition to downsizing, it is possible to eliminate the feeling of anxiety at the time of female local cleaning to the same level as the conventional one in which a plurality of nozzles are installed in parallel.
[0013]
  In this case, the one nozzle may be the second nozzle, and the other nozzle may be the first nozzle. If it carries out like this, the 1st nozzle for female local washing | cleaning can be located in the standby position in the state accommodated in the 2nd nozzle at the time of anal washing. Therefore, the bounce wash water at the time of anus cleaning can be blocked by the second nozzle itself, and it is possible to more reliably avoid the bounce wash water from being applied to the first nozzle for female local washing. For this reason, the anxiety at the time of a female local washing | cleaning can be eliminated more reliably.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
  Next, an embodiment of the sanitary washing apparatus according to the present invention will be described based on examples. First, the nozzle configuration of the sanitary washing device will be described. 1 is a schematic perspective view of a sub-assembly nozzle body 30 having two local cleaning nozzles, FIG. 2 is a cross-sectional view of the main part of the main part taken along the nozzle axis direction, and FIG. FIG. 4 is an enlarged sectional view taken along line 4-4 of FIG.
[0015]
  As shown in the figure, the sub-assembly nozzle body 30 includes a first nozzle 31 and a second nozzle 32 that eject the supplied cleaning water toward the human body local part. Both the first nozzle 31 and the second nozzle 32 are resin molded products molded in a columnar shape. The first nozzle 31 is housed in the second nozzle 32 with its axis aligned with the second nozzle 32. That is, the second nozzle 32 has a nozzle insertion hole 32a formed in the center following the outer shape (cylindrical shape) of the first nozzle 31, and the first nozzle 31 is inserted into the nozzle insertion hole 32a. . Thereby, the 1st nozzle 31 and the 2nd nozzle 32 are integrated, although it is a separate nozzle.
[0016]
  The inner diameter of the nozzle insertion hole 32 a is slightly larger than the outer diameter of the first nozzle 31. For this reason, the first nozzle 31 is guided by the nozzle insertion hole 32a and can move back and forth along the axis, and even the second nozzle 32 can move back and forth along the axis. In order to prevent the first nozzle 31 from rotating about the axis, a rotation stop is provided by, for example, a key groove and a key.
[0017]
  The first and second nozzles have connection fittings 33 and 34 connected to a cleaning water supply hose (not shown), and receive cleaning water through each fitting. As shown in FIG. 2, the first nozzle 31 includes a jet nozzle 35 at the nozzle tip, and the cleaning water that has flowed into the nozzle flow path 36 through the connection fitting 33 is jetted from the jet nozzle 35. The second nozzle 32 is also provided with a spout 37 at the tip of the nozzle, and the wash water that has flowed into the nozzle flow path 38 via the connection fitting 34 is spouted from the spout 37. In this case, as shown in FIGS. 3 and 4, the intra-nozzle passage 38 of the second nozzle 32 is formed so as to surround the nozzle insertion hole 32a, so that the effective passage area is widened. Accordingly, since the pressure loss when the cleaning water passes through the nozzle flow path 38 is reduced, the second nozzle 32 is suitable for jetting cleaning water with a high flow rate.
[0018]
  The end of the second nozzle 32 is an open recess 39 that is open at the bottom and surrounds the tip of the first nozzle 31. Therefore, when the first nozzle 31 spouts the cleaning water from the spout 35 in the state shown in FIG. 1 and FIG. 2, the spouted cleaning water rebounds from the inner wall surface of the opening recess 39 to the nozzle surface around the spout 35. Take it. For this reason, what is called self-cleaning which wash | cleans the jet nozzle 35 periphery of the 1st nozzle 31 with jet washing water is attained. Since the sub assembly nozzle body 30 has a cleaning chamber (not shown) above the tip of the second nozzle 32, the second nozzle 32 can also be self-cleaned.
[0019]
  Next, the sanitary washing device 40 of the embodiment having the sub assembly nozzle body 30 will be described. FIG. 5 is an exploded perspective view showing the sanitary washing device 40 together with the toilet bowl, and FIG. 6 shows the configuration of the sanitary washing device 40.SubroFIG. The sanitary washing device 40 includes a main body base 42 fixed to the upper surface of a toilet 41, a unit group 43 on the base, and a main body cover 46 on which a toilet seat 44 and a toilet lid 45 are attached so as to be freely opened and closed. It is installed in front of the washing water tank 47. The unit group 43 includes a sub-assembly nozzle body 30 and a nozzle unit 50 located substantially in the center, a water supply unit 52 for supplying cleaning water of appropriate temperature to the first and second nozzles of the sub-assembly nozzle body 30, The nozzle drive unit 54 that moves both nozzles forward and backward between the illustrated standby position and the target cleaning position in the apparatus main body, the drying unit 56 that blows hot air to dry the human body part, and the configuration of each unit A control unit 58 and the like that drive and control the members to execute local cleaning and drying are assembled and arranged on the upper surface of the main body base 42. The control unit 58 is provided with various buttons for instructing the start / stop of the local cleaning. Similar buttons are also provided on the remote controller 59.
[0020]
  In the sanitary washing device 40, the first nozzle 31 of the sub-assy nozzle body 30 in the nozzle unit 50 is used as an anal washing nozzle (anal nozzle), and the second nozzle 32 is used in a female local area so that the anal washing and the female local washing can be performed. A cleaning nozzle (bidet nozzle) is used. The nozzle drive unit 54 includes a nozzle drive system that moves the first nozzle 31 back and forth between a standby position in the main body and a cleaning position for anal cleaning (anal cleaning position), and a second nozzle 32 that is positioned in the female position. And a nozzle drive system that advances and retreats over a cleaning position (bidet cleaning position) for cleaning. The control unit 58 includes an electronic control unit 58A having logic operation circuit devices such as a CPU, ROM, and RAM. Then, the control unit 58 selectively uses the both drive systems in accordance with the button operation of the user, and advances the first nozzle 31 or the second nozzle 32 to the cleaning position. Further, the control unit 58 controls the water supply unit 52 according to the user's button operation to supply cleaning water to the corresponding nozzle, and the target cleaning location from the first nozzle 31 or the second nozzle 32 at the cleaning position. The washing water is spouted toward the anus or female part. Furthermore, the control unit 58 maintains and controls a cleaning water temperature in a hot water tank 53 (described later) of the water supply unit 52 at a set temperature. At this time, the control unit 58 inputs the detected water temperature of the temperature monitoring thermistor of the hot water tank 53, and controls energization of the sheathed heater in the tank according to the result.
[0021]
  Here, prior to the description of the state of nozzle driving and the state of cleaning water jetting after the local cleaning button is operated, the state of water supply to the water supply unit 52 and the configuration of the unit will be described.
[0022]
  The sanitary washing device 40 can be additionally installed on an existing toilet. That is, the main body base 42 can be fixed to the upper surface of the toilet bowl using the fixing holes on the upper surface of the existing toilet bowl, usually the fixing holes on the existing toilet seat or toilet lid support. When the main body base 42 is fixed in this way and the sanitary washing device 40 is additionally installed in the existing toilet bowl, the field work for washing water supply is performed as follows.
[0023]
  The additionally installed sanitary washing device 40 is independent of the water supply system around the existing toilet bowl, specifically, the water supply pipe to the toilet bowl wash water tank 47. Therefore, in order to supply cleaning water to the sanitary washing device 40 for local washing, the water supply pipe and the sanitary washing device 40 are connected. There are various methods. For example, as shown in FIG. 7, the middle of the water supply pipe HK extending from the stop cock SS to the toilet flushing water tank 47 is cut over a predetermined length A, and a branch fitting BK is incorporated at this cut location. Then, a branch pipe BH is connected from the branch fitting BK to the sanitary washing device 40 by a flexible hose or the like, and cleaning water is supplied to the water supply unit 52 of the sanitary washing device 40 by the branch fitting BK.
[0024]
  Alternatively, the existing stop cock SS is disassembled and removed, and a new stop cock having a branch structure is attached to the pipeline. Then, a branch pipe is connected to the sanitary washing device 40 from the branch portion of the new stop cock, and the washing water is supplied to the water supply unit 52.
[0025]
  Further, the following method can also be adopted. FIG. 8 is an explanatory diagram for explaining the structure of the water supply fitting 60 for supplying water to the sanitary washing device 40 and fixing the water supply pipe, and FIG. 9 shows the structure of the water supply fitting 60A and fixation to the water supply pipe. It is explanatory drawing demonstrated. As shown in the figure, the water supply fitting 60 includes a U-shaped frame 61 circumscribing the water supply pipe HK, a plate 62 screwed to the opening of the water supply pipe HK and sandwiching and fixing the water supply pipe HK together with the frame 61, and screwed into the frame 61. The branch metal fitting 63 is provided.
[0026]
  The branch fitting 63 integrally includes a tap portion 63a, a male screw portion 63b, a branch portion 63c, and a torque generating portion 63d from the right side in the drawing. The tap part 63a is a threaded tap with a tapered tip. An epoxy adhesive is applied as microbeads on the surface of the threaded tap portion of the tap portion 63a. The male screw portion 63b is screwed with the female screw of the frame 61, and pushes the branch metal fitting 63 rightward in the drawing. The branch part 62c includes a connection port for the branch pipe BH leading to the sanitary washing device 40, and a water supply flow path 63e that penetrates the tap part 63a and the male screw part 63b is connected to the branch pipe BH. The torque generating portion 63d has a star-shaped grip shape that can be easily gripped by the palm, and has a bottomed hole 63f into which a bar material such as a driver can be inserted on the outer peripheral side surface.
[0027]
  With this branch metal fitting 63, cleaning water can be supplied to the sanitary cleaning device 40 as follows. First, the frame 61 is engaged with the water supply pipe HK, and the frame 61 is fixed to the water supply pipe HK via the plate 62. Next, the torque generator 63d is gripped and the branch metal fitting 63 is rotated for threading. At this time, if the screw is rotated with a screwdriver or the like inserted into the bottomed hole 63f, the branch metal fitting 63 can be threaded and rotated with a large rotational torque. Thus, when threading rotation is performed, the tap portion 63a penetrates the pipe wall while screwing the female screw into the water supply pipe HK that is in contact with the tip, and is screwed with the water supply pipe HK. Connect to the pipe of the water supply pipe HK. At the time of this threading, the microbeaded epoxy adhesive applied to the surface of the threaded tap part spreads in the form of a film on the surface of the tap part 63a and the threaded part of the water supply pipe HK, and then hardens. . This hardened epoxy adhesive functions as a seal of the screwed portion between the tap portion 63a and the water supply pipe HK. Therefore, the cleaning water flows from the water supply pipe HK into the water supply flow path 63e of the branch fitting 63 without causing water leakage, and is supplied to the water supply unit 52 of the sanitary washing device 40 through the branch pipe BH. In addition, after the tap part 63a is screwed into the water supply pipe HK as described above, a set screw (not shown) is tightened from the side surface of the frame 61 toward the male screw part 63b, and the water supply fitting 60 is prevented from being removed.
[0028]
  As described above, the branch fitting 63 does not need to cut the water supply pipe HK when supplying the cleaning water to the sanitary washing device 40, and does not need to disassemble / remove the existing water stop cock. Therefore, according to this branch metal fitting 63, water can be easily supplied to the sanitary washing device 40. Moreover, it can be easily threaded by turning with a large rotational torque by a screwdriver or the like inserted into the bottomed hole 63f, and the branch fitting 63 can be easily connected to the water supply pipe HK. Furthermore, since it seals with an epoxy-type adhesive agent, it does not raise | generate a water leak and is preferable. It should be noted that chips and uncut residue generated when the water supply pipe HK is screwed are transported from the water supply pipe HK to the toilet flushing water tank 47, supplemented by the strainer at the tank water supply point, and then removed. It is.
[0029]
  A water supply fitting 60A shown in FIG. 9 may be used instead of the water supply fitting 60 described above. In this water supply fitting 60A, the branch pipe BH is connected to the end of the torque generating portion 63d, and the axis of the fitting and the pipe coincide. Therefore, the threaded rotation of the water supply fitting 60 is facilitated, and the work for supplying water to the sanitary washing device 40 is facilitated.
[0030]
  As shown in FIG. 10, the tap parts 63a of the water supply fittings 60 and 60A may have a conical tip and a small-diameter hole 63g from the water supply flow path 63e to the valley of the tap part. If it carries out like this, when the water supply piping HK is screwed by the tap part 63a, only a chip will be produced, and it will not leave uncut to a piping. Therefore, it is difficult to cause blockage of the piping due to not being left uncut.
[0031]
  In addition, when removing the sanitary washing apparatus 40 from a toilet bowl by moving etc., what is necessary is just to put on the stopper with the same screw shape as the tap part 63a. In addition, when the toilet is remodeled or the house is newly constructed, the sanitary washing device 40 can be installed in the toilet from the beginning, and a water supply pipe can be connected to the sanitary washing device 40. Therefore, in this case, it is not necessary to use the water supply fitting 60.
[0032]
  The water supply unit 52 that receives the supply of cleaning water in this way has a hot water tank 53 that warms the cleaning water to an appropriate temperature in advance (see FIG. 5). FIG. 11 is a schematic perspective view of the hot water tank 53. As shown in the drawing, the hot water tank 53 is formed by melting and fixing an upper tank 53a and a lower tank 53b with respective end ribs 53c and 53d. The hot water tank 53 is provided with a sheathed heater for warming water (not shown), a thermistor for temperature monitoring, a bimetal switch for preventing excessive temperature rise, a temperature fuse, and the like, which are provided in the upper tank 53a. Hold on to.
[0033]
  FIG. 12 is a cross-sectional view of a main part of the hot water tank 53 viewed in the vicinity of the end ribs 53c and 53d. As shown in the drawing, the center of the lower surface of the end rib 53c is a melt projection 53e whose lower end protrudes in a flat shape, and both sides thereof are a burr pool 53f and an end joint 53g that are recessed upward. Yes. The same applies to the end rib 53d, and the upper end is formed as a melt projection 53h protruding in a V-shaped depression shape, and both sides thereof are formed as burr pools 53i and end joints 53j that are recessed downward. Yes. And the warm water tank 53 is produced as follows.
[0034]
  First, the end ribs 53c and 53d are pressed so that the melt projection, the burr pool, and the end joints face each other. Next, in this state, the end ribs 53c and 53d are caused to frictionally vibrate left and right in the drawing. Then, the melting projections 53e and 53h generate heat, and both melting projections are melted and integrated by this heat. The molten burr generated at this time is accumulated in the burr pools 53f and 53i. When the heat fusion integration of the melt projections proceeds, the end joints 53g and 53j are also joined and integrated. At this time, the surface portion of the joint at both ends is melted by heat. Since the volume of the burr pools 53f and 53i is larger than the amount of melt burr generated by melting of the melt projections, the end ribs are not melted while the end joints are carelessly separated. Thus, when joining of the end joint portion occurs, vibration is stopped and cooling is performed. Thereby, the upper tank 53a and the lower tank 53b are melted and fixed over the entire surface of the end ribs, and the hot water tank 53 in which the upper and lower tank portions are firmly melted and fixed is completed. At this time, the burr itself accumulated in the burr pool is also cured by subsequent cooling, and contributes to melting and fixing of the tank.
[0035]
  This melt-fixed structure can be improved as follows. FIG. 13 is a cross-sectional view of a main part of the end ribs 53c and 53d in which the melt fixing structure shown in FIG. 12 is improved. The end ribs 53c and 53d shown in FIG. 13 are provided with two melting projections 53e and 53h that are approximately half the width shown in FIG. 12, and have central burr pools 53k and 53m therebetween. That is, it has double the melt projections that cause melt fixation over the periphery of the end ribs. Even in the end ribs 53c and 53d, the two melting protrusions 53e and 53h are melted and integrated by heat, and the upper tank 53a and the lower tank 53b are firmly melted and fixed over the entire end rib. The hot water tank 53 is completed. The hot water tank 53 having a melt-fixed structure shown in FIG. 13 has the following advantages.
[0036]
  In the case shown in FIG. 12, there is one melting projection 53e, 53h to be melted and integrated, and the melting of this projection exerts the fixing force of the upper and lower tanks. It is necessary to secure to some extent. For this reason, since melting occurs in the wide melting projections 53e and 53h, the melting degree differs in the width direction of the melting projections 53e and 53h, and the fixing force may vary in the width direction. On the other hand, in the fusion projections 53e and 53h shown in FIG. 13, since each projection has a narrow width, not only the degree of melting in the width direction but also the fixing force becomes uniform. In addition, since the melted portion capable of obtaining such a uniform fixing force, that is, the melt projections 53e and 53h are doubled, a higher fixing force can be obtained in the width direction of the end rib. It is possible to fix the upper and lower tank parts more firmly. As a result, the reliability against water leakage can be improved, which is preferable.
[0037]
  Next, the state of nozzle driving by the sanitary washing device 40 using the sub assembly nozzle body 30 and the state of washing water ejection will be described. FIG. 14 is a main part perspective view showing a state of anus cleaning using the first nozzle 31, and FIG. 15 is a main part perspective view showing a state of bidet cleaning using the second nozzle 32. First, anal cleaning will be described.
[0038]
  When the anal washing button of the control unit 58 or the remote controller 59 is operated, the control unit 58 (see FIG. 6) outputs a water supply signal to the first nozzle 31 to the water supply unit 52 prior to nozzle driving. Thereby, the first nozzle 31 receives the supply of the cleaning water from the water supply unit 52 at the standby position TP shown in FIG. The washing water ejected in this manner rebounds at the inner wall surface of the opening recess 39 at the tip of the second nozzle 32 and is applied to the nozzle surface around the ejection port 35. Self-cleaning is performed by the rebound washing water, and the area around the spout 35 is washed prior to anal washing.
[0039]
  Thereafter, the control unit 58 outputs a water supply stop signal to the water supply unit 52 to stop water supply to the first nozzle 31 and complete self-cleaning. Next, the control unit 58 outputs a drive signal (advance signal) for causing the first nozzle 31 to advance from the standby position TP to the anal cleaning position KP to the nozzle drive unit 54. As a result, the first nozzle 31 advances to the anal cleaning position KP alone and stops at the position as shown in FIG. 14 while being guided by the nozzle insertion hole 32a of the second nozzle 32. Thus, when the first nozzle 31 reaches the anus cleaning position KP, the control unit 58 outputs a water supply signal for anal cleaning to the water supply unit 52. As a result, washing water is ejected from the jet nozzle 35 of the first nozzle 31 at the anal washing position KP toward the anus, and the anus is washed with this washing water. During the anal cleaning by the first nozzle 31, the second nozzle 32 remains in the standby position TP.
[0040]
  The above-described anal cleaning is continued until the stop button is operated. When the button is operated, the control unit 58 waits for the water supply stop signal for the water supply unit 52 and the first nozzle 31 for the nozzle drive unit 54. A drive signal (retraction signal) for retreating to the position TP is output. Thereby, the 1st nozzle 31 stops the washing water jet for anus cleaning, and it resets back to standby position TP. Note that after returning to the standby position TP, the self-cleaning described above is performed again.
[0041]
  When the bidet washing button of the control unit 58 or the remote controller 59 is operated, a water supply signal to the second nozzle 32 is output from the control unit 58 to the water supply unit 52. As a result, the second nozzle 32 ejects cleaning water from its ejection port 37 to a cleaning chamber (not shown) at the standby position TP. Therefore, even in the case of bidet cleaning, self-cleaning is performed in the same manner as the anal cleaning by the first nozzle 31, and the area around the ejection port 37 is cleaned prior to bidet cleaning.
[0042]
  After this self-cleaning is completed, the control unit 58 outputs a drive signal (advance signal) for causing the second nozzle 32 to advance from the standby position TP to the bidet cleaning position BP ahead of the anal cleaning position KP. To do. Thereby, the second nozzle 32 advances to the bidet cleaning position BP and stops as shown in FIG. Then, since the water supply signal for bidet washing is output from the control unit 58 to the water supply unit 52, the washing water is ejected from the outlet 37 of the second nozzle 32 at the bidet washing position BP toward the female local area. Women's local cleaning (bidet cleaning) is carried out. During the bidet cleaning by the second nozzle 32, the first nozzle 31 remains in the standby position TP.
[0043]
  Even in the bidet cleaning described above, the operation is continued until the stop button is operated in the same manner as the anal cleaning, and when the button is operated, the ejection of cleaning water from the second nozzle 32 is stopped and the second nozzle 32 is in a standby state. Return to position TP. Note that after returning to the standby position TP, the self-cleaning described above is performed again.
[0044]
  As explained above, thisThe fruitAccording to the sanitary washing device 40 of the embodiment, there are the following advantages. First, in the present embodiment, the subassembly nozzle body 30 in which the first nozzle 31 is housed in the second nozzle 32 and the both nozzles are integrated is used, and the first nozzle 31 is disposed in the nozzle housing. It was stored in a nozzle insertion hole 32a following the outer shape. Therefore, the sub-assembly nozzle body 30 can be made to be one in which the first nozzle 31 is housed and integrated in the first nozzle 31 without wasteful space, and thus can be made smaller than the conventional one in which a plurality of nozzles are simply installed in parallel. Can be planned. In addition, the sub assembly nozzle body 30 in which the first nozzle 31 is housed in the second nozzle 32 has an appearance as a single nozzle rather than a plurality of nozzles and can be handled like a single nozzle, thus improving the appearance and handling. Is also easier. Furthermore, since the first nozzle 31 is guided by the nozzle insertion hole 32a, it is preferable that the first nozzle 31 can be easily advanced and retracted during anus cleaning.
[0045]
  The first nozzle 31 is an anal nozzle and the second nozzle 32 is a bidet nozzle, and the second nozzle 32 is positioned at the standby position TP when the first nozzle 31 performs anal cleaning. Therefore, as shown in FIG. 14, it is possible to prevent the rebound washing water bounced off by the human body during the anus cleaning from being applied to the second nozzle 32, and the sanitary feeling of the bidet nozzle is hardly impaired. As a result, according to the present embodiment, in addition to downsizing, it is possible to eliminate the anxiety at the time of female local cleaning to the same extent as in the conventional one in which a plurality of nozzles are installed in parallel.
[0046]
  Further, in the present embodiment, the bidet nozzle is the second nozzle 32 capable of forming an in-nozzle passage having a large effective passage area and a small pressure loss as shown in FIG. Therefore, since the female local cleaning can be executed with a large flow of flushing water jet, the feeling of cleaning of the female local can be enhanced.
[0047]
  AboveFruitThe sanitary washing device 40 of the embodiment can be modified as follows. FIGS. 16 to 20 are explanatory views for explaining modifications of the sub-assembly nozzle body 30. In the first modified example, as shown in the plan view of the periphery of the ejection port in FIG. 16 (a) and the cross-sectional view in FIG. 16 (b), the second nozzle 32, which is a bidet nozzle, Instead of an outlet, the outlet is a collection of a plurality of small diameter outlets. In this way, a relatively wide range can be cleaned at once, and the cleaning feeling at that time can be soft.
[0048]
  In the second modified example, as shown in FIG. 17, the second nozzle 32 that is a bidet nozzle has a jet outlet 37 that is symmetrically arranged on the left and right and faces the same cleaning point. In this way, the female local area can be washed from the left and right at the same time. In the third modified example, as shown in FIG. 18, the second nozzle 32 that is a bidet nozzle has jet outlets 37 that are symmetrically arranged so as to collide with the jet cleaning water before the cleaning point. In this way, the female local area can be washed from the left and right at the same time, and since the wash water after the collision is applied to the female local area, a relatively wide area can be washed at a time, and the washing feeling at that time can be made soft.
[0049]
  Further, it can be modified as follows. That is, it can deform | transform so that the 1st nozzle 31 may be a bidet nozzle and the 2nd nozzle 32 may be an anal nozzle. In this modification, the first nozzle 31 that is a bidet nozzle is not only positioned at the standby position TP but also the first nozzle 31 is housed in the second nozzle 32 when the second nozzle 32 cleans the anus. Therefore, the bounce wash water at the time of anal washing can be blocked by the second nozzle 32 itself, and this bounce wash water is not applied to the first nozzle 31 at all. For this reason, according to this modification, since the sanitary feeling about the bidet nozzle can be enhanced, the anxiety at the time of female local cleaning by the first nozzle 31 can be more reliably eliminated.
[0050]
  In the present embodiment, the sanitary washing device 40 is designed to clean the anus and bidet with the first nozzle 31 and the second nozzle 32, but may be modified to be a sanitary washing device dedicated to anus cleaning. In this case, both the first nozzle 31 and the second nozzle 32 are driven from the standby position TP to the anal cleaning position KP, and the first nozzle 31 and the second nozzle 32 have different ejection forms of cleaning water. do it. For example, a general cleaning water jet that concentrates jetting of cleaning water from the first nozzle 31 as one point is intended, and a second nozzle 32 that jets cleaning water at a high flow rate or jets of cleaning water mixed with bubbles is intended. it can. This is preferable because the anal cleaning can be performed with various cleaning feelings. FIG. 19 is an explanatory diagram for explaining a sub-assembly nozzle body 30 of a modified example (fourth modified example) used in a sanitary washing device dedicated to anus cleaning.
[0051]
  As shown in FIG. 19, in the sub-assembly nozzle body 30 of the fourth modified example, the second nozzle 32 is concentric with a small diameter around the through-hole 37a that is formed so as to surround the ejection port 35 of the first nozzle 31. The nozzles 37 are arranged in a scattered manner. And the 1st nozzle 31 and the 2nd nozzle 32 are made to advance to the bidet washing position BP with integral. In this modification, normally, concentrated cleaning by the first nozzle 31 is performed, and when a special button (for example, a soft button) is operated, the cleaning water is ejected in an annular shape from the outlet 37 of the second nozzle 32. Let As described above, according to this modification, it is possible to selectively execute anal cleaning using concentrated jet cleaning water and anal cleaning using annular jet cleaning water, and various local cleanings can be executed. In this modification, both the first nozzle 31 and the second nozzle 32 advance to the anal cleaning position KP in any anal cleaning. Note that only the first nozzle 31 is advanced to the anus cleaning position KP when the anus is cleaned with the concentrated spray cleaning water, and only the second nozzle 32 is advanced to the anus cleaning position KP when the anus is cleaned with the annular spray cleaning water. You can also. In this case, the second nozzle 32 does not require the through hole 37a.
[0052]
  Further, as shown in FIG. 20 showing the fifth modified example, when the first nozzle 31 is housed in the second nozzle 32, the two nozzles can be modified so as to be eccentrically arranged vertically. Furthermore, not only the first nozzle 31 and the second nozzle 32 but also a third nozzle can be added and the third nozzle can be modified to be stored concentrically or eccentrically with the first nozzle 31.
[0053]
  Further, in the sub assembly nozzle body 30, the first nozzle 31 is accommodated over the entire length of the second nozzle 32, but the first nozzle 31 is partially covered in the length direction of the second nozzle 32. Can be stored. For example, the nozzle insertion hole 32a may be formed only in the range of about 1/3 of the nozzle length from the tip side of the second nozzle 32, and the first nozzle 31 may be exposed in other ranges. In addition, the nozzle insertion hole 32a is a hole that extends around the entire circumference of the first nozzle 31, but this insertion hole covers about 2/3 of the circumference of the first nozzle 31, for example, the lower end opens in the nozzle longitudinal direction. It can also be made. Further, the nozzle insertion hole 32a may have a number of grooves in the nozzle longitudinal direction on the inner peripheral surface of the insertion hole so as to suppress sliding resistance with the first nozzle 31.
[0054]
  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and embodiments, and can of course be implemented in various modes without departing from the gist of the present invention. is there.
[0055]
  For example, the bidet nozzle in the embodiment can be made by coating fine particles of metal (Ag, Ni / Cr alloy, etc.) that hinders the growth of bacteria around the washing water outlet. By doing so, it is possible to make it difficult for bacteria to grow around the spout, so that a sense of cleanliness about the bidet nozzle is increased and a sense of security is further increased, which is preferable. Further, the above-mentioned bidet nozzle can be formed by coating fine particles of a photocatalyst around the washing water outlet. This photocatalyst generates excited electrons and holes by the energy of the irradiated light and functions as a catalyst, and generates hydroxyl groups through the generation of hydroxyl radicals in the presence of moisture or moisture and oxygen on the catalyst surface. It is. In a bidet nozzle coated with such a photocatalyst, the surface of the coated region can always be present in high density under light irradiation to make the surface highly hydrophilic. Therefore, even if dirt adheres to the periphery of the washing water jet outlet, the dirt can be quickly and reliably removed by the washing water applied during self-cleaning. Is further preferred. As this photocatalyst, TiO₂ZnO, SnO₂TiO, etc.₂Is preferable in terms of easy procurement.
