Description

  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.

  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.

  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.

  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.

  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.

  Washing of women's local area is to wash away bleeding and tissue waste during menstruation with erupted washing 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, and this bleeding or tissue waste may adhere to the epidermis in the area 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 washing, 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.

  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.

In order to solve at least a part of the problem, the sanitary washing device of the present invention has the following configuration. That is,
A sanitary washing device for washing a local part of a human body seated on a toilet seat,
First and second nozzles that are capable of advancing and retreating between a standby position at the time of cleaning standby and a cleaning position for local cleaning, and that jets cleaning water to the local part;
A nozzle driving source and first and second output shafts disposed on the left and right sides of the nozzle so that the first and second output shafts are positioned on the left and right with respect to the advancing and retreating direction of the nozzle; Output means for selectively transmitting the output of the drive source to either the first or second output shaft;
A first transmission means for connecting the first nozzle and the first output shaft, and converting the first output shaft output into an advancing / retreating operation between the cleaning position and the standby position and transmitting the first nozzle; ,
A second transmission means for connecting the second nozzle and the second output shaft, converting the second output shaft output into an advancing / retreating operation between the cleaning position and the standby position, and transmitting the second nozzle; It is characterized by providing.

  In the sanitary washing device of the present invention having the above-described configuration, the first and second output shafts disposed on the left and right sides of the drive source are positioned on the left and right with respect to the advancing / retreating direction of the nozzles and associated with the first and second nozzles. . Therefore, only a single drive source is required, and the drive source can be disposed between the first and second nozzles or can be disposed so as to overlap both nozzles. For this reason, both the nozzles, the drive source and output means necessary for the advance and retreat of the nozzles, and the first and second transmission means can be disposed close to each other, and the size can be reduced.

Another sanitary washing device of the present invention is
A sanitary washing device for washing a local part of a human body seated on a toilet seat,
First and second nozzles that are capable of advancing and retreating between a standby position at the time of cleaning standby and a cleaning position for local cleaning, and that jets cleaning water to the local part;
A motor that generates a driving force for driving the first nozzle forward and backward between the standby position and the cleaning position; and a transmission member that transmits the driving force of the motor to the first nozzle for the forward and backward driving. and driving dynamic means,
When the second nozzle advances and retreats, the first nozzle and the second nozzle are connected, and the second nozzle is moved between the standby position and the cleaning position together with the first nozzle driven to advance and retreat by the driving means. And nozzle connecting means for driving forward and backward.

  In the sanitary washing device of the present invention having the above configuration, the first nozzle and the second nozzle are connected by the nozzle connecting means, so that the driving means for the advance / retreat driving of the first nozzle is also used for the advance / retreat driving of the second nozzle. Can be shared. Therefore, only a single drive means is required, and both nozzles can be arranged in parallel or concentrically so that they can be connected when the second nozzle is advanced or retracted. For this reason, both the nozzles and the driving means and nozzle connecting means necessary for the advance and retreat of the nozzles can be arranged close to each other, and the size can be reduced.

Another sanitary washing device of the present invention is:
A sanitary washing device for washing a local part of a human body seated on a toilet seat,
First and second nozzles that are capable of advancing and retreating between a standby position at the time of cleaning standby and a cleaning position for local cleaning, and that jets cleaning water that has been supplied with water to the local area,
Nozzle driving means for driving the first and second nozzles forward and backward;
Driven by receiving the supply pressure of the cleaning water, and depending on the supply state of the cleaning water to the first and second nozzles, the output of the nozzle drive means is set to either the first or second nozzle as a nozzle advance / retreat operation. And a transmission means for selectively transmitting to.

  In the sanitary washing apparatus of the present invention having the above-described configuration, when the first and second nozzles are driven forward and backward, the output of the nozzle driving means is selectively transmitted according to the supply state of the washing water to both nozzles. Since the output transmission at this time is performed by the supply pressure of the washing water, a drive source for output transmission is not required. Therefore, the structure can be simplified and the size of the apparatus can be reduced through this.

  In the above-described sanitary washing apparatus, the arrangement form of the first and second nozzles can take any appropriate form, and the form in which the first nozzle is housed in the second nozzle or the form in which both nozzles are concentrically or vertically arranged eccentrically. Further, it is possible to adopt a form in which flat portions extending in the longitudinal direction of the nozzles are arranged so as to face each other and both nozzles are arranged adjacent to each other in the left and right or up and down directions. Moreover, after adopting these forms, the positional relationship between the female local cleaning nozzle and the local cleaning nozzle can be regulated such that the female local cleaning nozzle is rebounded and no washing water is applied.

  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.

  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.

  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.

  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.

  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. Accordingly, when the first nozzle 31 spouts the cleaning water from the jet outlet 35 in the state shown in FIGS. 1 and 2, the jet cleaning water bounces off the inner wall surface of the opening recess 39 and reaches the nozzle surface around the jet outlet 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.

  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 is a block diagram showing the configuration of the sanitary washing device 40. 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.

  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 as a female local 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.

  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. 7 is a main part perspective view showing the state of anal cleaning using the first nozzle 31, and FIG. 8 is a main part perspective view showing the state of bidet cleaning using the second nozzle 32. First, anal cleaning will be described.

  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. As a result, 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.

  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. Accordingly, the first nozzle 31 advances to the anal cleaning position KP alone and stops at the position as shown in FIG. 7 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.

  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.

  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.

  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.

  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.

  As described above, according to the sanitary washing device 40 of the first 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.

  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. 7, 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 less likely to be 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.

  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.

  The sanitary washing device 40 of the first embodiment described above can be modified as follows. 9 to 13 are explanatory views for explaining modifications of the sub-assembly nozzle body 30. FIG. In the first modification, as shown in the plan view of the periphery of the ejection port in FIG. 9A and the cross-sectional view in FIG. 9B, the second nozzle 32, which is a bidet nozzle, has a single ejection port 37. 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.

  In the second modified example, as shown in FIG. 10, the second nozzle 32 that is a bidet nozzle has a jet outlet 37 that is symmetrically arranged on the left and right and that 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 modification, as shown in FIG. 11, the second nozzle 32 that is a bidet nozzle has jet outlets 37 that are arranged symmetrically on the left and right so that the jetted cleaning water hits 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.

  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.

  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. 12 is an explanatory diagram for explaining a sub-assembly nozzle body 30 of a modification (fourth modification) used in a sanitary washing device dedicated to anus cleaning.

  As shown in FIG. 12, 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 evacuated so as to surround the jet nozzle 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.

  Further, as shown in FIG. 13 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.

  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.

  Next, another embodiment of the subassembly nozzle body having the first and second nozzles will be described. In addition, about the member same as the above-mentioned sub assembly nozzle body 30, or the member which performs the same function, the code | symbol used by description of the sub assembly nozzle body 30 shall be used. FIG. 14 is a schematic perspective view of a subassembly nozzle body 30A in which the first and second nozzles are arranged in parallel, FIG. 15 is a cross-sectional view of the nozzle tip, and FIGS. 16 and 17 use the subassembly nozzle body 30A. It is explanatory drawing explaining the mode of anal washing | cleaning and female local washing | cleaning.

  As shown in the figure, the sub assembly nozzle body 30A includes a first nozzle 31A and a second nozzle 32A adjacent to each other in the left and right direction with respect to the longitudinal direction of the nozzle. Both nozzles have a semicircular cross-sectional shape, and have flat portions 70 and 71 extending in the longitudinal direction of the nozzle, respectively, and the flat portions 70 and 71 are joined to face each other. The first nozzle 31A and the second nozzle 32A are inserted and arranged in the cylindrical ring 72 in this state, and are integrated.

  The inner diameter of the cylindrical ring 72 is slightly larger than the outer diameter of the circle in which the two nozzles are joined at the flat portion. For this reason, the first nozzle 31A and the second nozzle 32A are guided by the through-hole of the cylindrical ring 72 and the flat portions 70 and 71 of each other, and can move back and forth independently along the axis. In order to prevent both the first nozzles 31 from rotating about the axial center with respect to the cylindrical ring 72, for example, a rotation stop is provided by a key groove and a key.

  The first and second nozzles include jet outlets 35A and 37A for jetting the cleaning water supplied through the respective connecting fittings 33 and 34. Even in the sanitary washing device 40 having the sub assembly nozzle body 30A, the first nozzle 31A is an anal nozzle and the second nozzle 32A is a bidet nozzle. Therefore, the second nozzle 32A has a nozzle flow path 38A and a jet outlet 37A suitable for flushing flush water with a large flow rate for cleaning the female local area. Even in the sub assembly nozzle body 30A, since there is a cleaning chamber (not shown) above the tips of both nozzles, both of these nozzles can be self-cleaned.

  In the sanitary washing device 40 having the above-described sub assembly nozzle body 30A, as shown in FIG. 16, the first nozzle 31A is advanced from the standby position TP to the anal washing position KP independently during anal washing. Then, similarly to the first embodiment, anal cleaning is performed with the first nozzle 31A. In addition, as shown in FIG. 17, the second nozzle 32A is advanced independently to the bidet cleaning position BP ahead of the anal cleaning position KP at the time of female local cleaning, and the second nozzle 32A is used for female by the same as in the first embodiment. Perform local cleaning. The same applies to self-cleaning before and after local cleaning.

  As described above, according to the sanitary washing device 40 having the sub-assembly nozzle body 30A, there are the following advantages. First, in the present embodiment, the first nozzle 31A and the second nozzle 32A are disposed adjacent to the left and right in the longitudinal direction of the nozzle, and the flat portions 70 and 71 are bonded to each other. For this reason, the first and second nozzles can be made smaller than the conventional one simply installed in parallel. Further, both the first and second nozzles are nozzles having a shape (semicircular shape) obtained by dividing a single nozzle shape (circular shape) into multiple portions. Therefore, the appearance can be improved as an appearance closer to a single nozzle than as a plurality of nozzles. Moreover, since the first nozzle 31A and the second nozzle 32A are inserted into the cylindrical ring 72 in a state of being adjacently disposed through the joining of the flat portions 70 and 71, it can be easily handled like a single nozzle, which is preferable.

  Similarly to the first embodiment, the first nozzle 31A is an anal nozzle, the second nozzle 32A is a bidet nozzle, and the second nozzle 32A is positioned at the standby position TP when the first nozzle 31 performs anal cleaning. Therefore, as shown in FIG. 16, it is possible to prevent the rebound washing water bounced off by the human body at the time of anus cleaning from being applied to the second nozzle 32A, and the sanitary feeling of the bidet nozzle is hardly impaired. As a result, even when the sub-assy nozzle body 30A is used, in addition to downsizing, the anxiety at the time of female local cleaning can be eliminated to the same extent as in the conventional one in which a plurality of nozzles are installed in parallel.

  This sub assembly nozzle body 30A can also be applied to a sanitary washing device dedicated to anal washing. In this case, as described above, both the first nozzle 31A and the second nozzle 32A are driven to the anal cleaning position KP, and the ejection form of the washing water may be different for each nozzle. The sub assembly nozzle body 30A can be shortened in the left-right direction as a plurality of nozzles arranged in parallel by joining the flat portions 70 and 71, and both the jet nozzles of the first nozzle 31A and the second nozzle 32A can be brought close to each other. Accordingly, even if any of the first nozzle 31A and the second nozzle 32A is used for anal cleaning, the cleaning water can be ejected without removing the anus.

  The sub assembly nozzle body 30A can be modified as follows. FIG. 18 is a cross-sectional view of a modification of the sub assembly nozzle body 30A. As shown in the figure, in this modification, the first nozzle 31A has a groove 73 in the flat portion 70 along the longitudinal direction of the nozzle, and the second nozzle 32A has a key 74 that enters the groove 73 in the flat portion 71. . Therefore, the first nozzle 31A and the second nozzle 32A are united by the groove 73 and the key 74, and are guided by the groove and the key so as to be between the standby position TP and the anal cleaning position KP or the bidet cleaning position BP. Can advance and retreat. For this reason, the cylindrical ring 72 is not required.

  Next, a sub assembly nozzle body according to another embodiment will be described. FIG. 19 is a schematic perspective view of a sub assembly nozzle body 30B provided with a third nozzle in parallel with the first and second nozzles. As illustrated, the sub assembly nozzle body 30B includes a third nozzle 75 between the first nozzle 31A and the second nozzle 32A. The third nozzle 75 has flat portions 76 and 77 at the left and right ends, and is adjacent to the first and second nozzles so that these flat portions are joined to the flat portions 70 and 71 of the first and second nozzles. Has been placed. The first to third nozzles are inserted into the cylindrical ring 72 and integrated in this state, and the so-called oval shape is divided into a left and right semicircular portion and a portion therebetween. The third nozzle 75 is an anal nozzle having a spout 78 capable of ejecting washing water in a form different from that of the first nozzle 31A.

  In the sanitary washing device 40 having the above-described sub assembly nozzle body 30B, the first nozzle 31A and the third nozzle 75 are advanced from the standby position TP to the anal washing position KP at the time of anal washing. Then, washing water is ejected from either the first nozzle 31A or the third nozzle 75 to perform anal cleaning. Further, at the time of female local cleaning, the second nozzle 32A is independently advanced to the bidet cleaning position BP ahead of the anal cleaning position KP, and the female local cleaning is performed with the second nozzle 32A as in the first embodiment (see 24). ). The same applies to self-cleaning before and after local cleaning. Note that whether the first nozzle 31A or the third nozzle 75 is the water supply target nozzle is determined according to a predetermined button operation.

  As described above, according to the sanitary washing device 40 having the sub assembly nozzle body 30B, it is possible to achieve downsizing, avoidance of anxiety at the time of female local washing, and the like, similar to the sub assembly nozzle bodies 30 and 30A. In addition, by having the third nozzle 75, anal cleaning in various forms can be realized without causing an increase in size of the nozzle.

  Next, a sub-assembly nozzle body according to still another embodiment will be described. 20 is a schematic perspective view of a subassembly nozzle body 30C having first and second nozzles arranged in parallel vertically, FIG. 21 is a longitudinal sectional view of the nozzle tip, and FIGS. 22 and 23 are subassembly nozzle bodies. It is explanatory drawing explaining the mode of anal washing | cleaning and female local washing | cleaning using 30C.

  As shown in the figure, the sub assembly nozzle body 30C is different from the sub assembly nozzle body 30A in the parallel direction of the nozzles, and the first nozzle 31C and the second nozzle 32C are opposed to and joined to the flat portions 70 and 71, respectively. Arranged adjacent to the top and bottom. Both nozzles have an arcuate cross-sectional shape in order to shorten the vertical dimension. Note that, like the sub assembly nozzle body 30A, both nozzles are inserted into a cylindrical ring (not shown) in this state, and are integrated.

  The first nozzle 31C has an ejection port 35C on the curved surface side, and the second nozzle 32C has an ejection port 37C on the flat portion 71 side. And the nozzle tip part lower end side of the 1st nozzle 31C is notched so that a space | gap may be formed between the 2nd nozzle 32C, and the said space | gap is made into the opening recessed part 39C. Therefore, when the second nozzle 32C spouts the cleaning water from the ejection port 37C in the state shown in FIGS. 20 and 21, the ejection cleaning water rebounds on the wall surface of the opening recess 39C and is applied to the nozzle surface around the ejection port 37C. . For this reason, the self-cleaning which wash | cleans the jet nozzle 37C periphery of the 2nd nozzle 32C with jet washing water is implemented. The first nozzle 31C is also self-cleaned by a cleaning chamber (not shown) above the tip of the first nozzle 31C. In the sanitary washing device 40 having the sub assembly nozzle body 30C, the first nozzle 31C is an anal nozzle and the second nozzle 32C is a bidet nozzle. Therefore, in the second nozzle 32C, in order to wash the female local area, the nozzle flow path 38C and the jet outlet 37C are suitable for jetting a large amount of washing water.

  In the sanitary washing device 40 having the above-described sub assembly nozzle body 30C, as shown in FIG. 22, the first nozzle 31C is advanced from the standby position TP to the anal washing position KP alone during anus cleaning. Then, similarly to the first embodiment, anal cleaning is performed with the first nozzle 31C. Further, as shown in FIG. 23, the second nozzle 32C is made to advance independently to the bidet cleaning position BP ahead of the anal cleaning position KP at the time of female local cleaning, and the second nozzle 32C is used for female by the same as in the first embodiment. Perform local cleaning. The same applies to self-cleaning before and after local cleaning.

  As described above, according to the sanitary washing device 40 having the sub-assembly nozzle body 30C, there are the following advantages. First, in the present embodiment, both the first and second nozzles are disposed adjacent to each other in the vertical direction with respect to the longitudinal direction of the nozzle, and the flat portions 70 and 71 are joined to each other. For this reason, the first and second nozzles can be made smaller than the conventional one simply installed in parallel. In addition, since both the first and second nozzles have an arcuate cross section, the vertical dimension can be particularly shortened. Further, as described above, it is possible to improve the appearance and simplify the handling.

  In the same manner as in the first embodiment, the second nozzle 32C is positioned at the standby position TP and the second nozzle 32C is covered with the first nozzle 31C when the anus is cleaned by the first nozzle 31C. Therefore, the bounce wash water at the time of anus cleaning can be blocked by the first nozzle 31C itself, and this bounce wash water is never applied to the second nozzle 32C. For this reason, even if the sub assembly nozzle body 30C is used, the sense of hygiene about the bidet nozzle can be enhanced, so that the anxiety at the time of female local cleaning by the second nozzle 32C can be more reliably eliminated. Note that the sub-assembly nozzle body 30C can also be applied to a sanitary washing device dedicated to anus cleaning, similar to the sub-assembly nozzle body 30A.

  Next, other embodiments (second to fifth embodiments) will be described. These embodiments are characterized by the configuration of a nozzle drive system that drives each of a plurality of nozzles. FIG. 24 is a schematic perspective view of the nozzle drive unit 80 included in the sanitary washing device of the second embodiment, and FIG. 25 is a schematic diagram schematically showing the configuration of the nozzle drive unit 80. As shown in the figure, the nozzle drive unit 80 is integrated with the sub assembly nozzle body 30C, and has the following configuration in order to advance and retract the first nozzle 31C and the second nozzle 32C, respectively.

  The nozzle drive unit 80 includes a motor 81, a first clutch 82, and a second clutch 83. The motor 81 is a so-called double-axis motor that includes a rotating shaft 81a penetrating from the motor casing, and is a stepping motor that can rotate forward and backward. The 1st clutch 82 and the 2nd clutch 83 are clutches of appropriate structures, such as a magnet clutch, and have output shafts 82a and 83a, respectively. The first and second clutches are fixed to the left and right of the motor 81 so that the rotating shaft and both output shafts are linearly arranged. Since such a motor / clutch arrangement is adopted, the motor 81 and the clutch output shafts 82a and 83a positioned on the left and right of the motor 81 are positioned on the left and right with respect to the advancing / retreating direction of the first nozzle 31C and the second nozzle 32C. The left and right clutches can be arranged. In other words, the motor 81 can be disposed below the sub assembly nozzle body 30C, and the output shafts 82a and 83a of the clutch are associated with the first nozzle 31C and the second nozzle 32C, respectively.

  The output shaft 82a of the first clutch 82 is a drive pulley 84 for advancing and retracting the first nozzle 31C (anal nozzle), and the output shaft 83a of the second clutch 83 is a drive pulley 85 for driving the second nozzle 32C (bide nozzle). , Respectively. The driving pulley 84 constitutes a driving system for the first nozzle 31C together with the timing belt 84a and the two driven pulleys 84c and 84d. The timing belt 84a is connected and fixed to the first nozzle 31C by a latch 84e. The same applies to the drive pulley 85, and the timing belt 85a is connected and fixed to the second nozzle 32C by a latch 85e. Both the timing belts form a linear track along the advancing / retreating direction of both nozzles between the driven pulleys 84c, 84d, and converts the motor rotation into the advancing / retreating operation of the nozzle. Both clutches are selectively driven by a control unit (not shown).

  That is, when the anal washing button is operated, the first clutch 82 is turned on and the second clutch 83 is turned off. Therefore, the rotation of the motor 81 is transmitted to the drive pulley 84 via the output shaft 82a of the first clutch 82. The rotation of the drive pulley 84 is converted into a nozzle advance / retreat operation along a linear locus between the two driven pulleys by the timing belt 84a. Therefore, in this case, the first nozzle 31C is advanced from the standby position TP shown in the drawing to its cleaning position (anus cleaning position KP (see FIG. 22)) alone. Then, cleaning water is supplied to the first nozzle 31C, and anal cleaning is performed. If the stop button is operated, the motor 81 is driven in reverse while maintaining the control state of the clutch, so that the first nozzle 31C moves back to the standby position TP. On the other hand, if the bidet washing button is operated, the second clutch 83 is turned on and the first clutch 82 is turned off. Therefore, similarly to the above, the second nozzle 32C can be driven forward and backward independently between the standby position TP and the bidet cleaning position BP (see FIG. 23). During anal cleaning and bidet cleaning, drive signals of different driving amounts are output from the control unit to the motor 81 so that the corresponding nozzles can advance to the respective cleaning positions (anal cleaning position KP, bidet cleaning position BP). The

  According to the sanitary washing device of the second embodiment described above, since the sub-assembly nozzle body 30C is used as the local washing nozzle, the effects described above by the nozzle body (miniaturization, relief of anxiety during female local washing, etc.) ) Can be played. In the sanitary washing device of the second embodiment, the nozzle drive unit 80 in which the motor 81, the first and second clutches, and the like are arranged together is arranged below the sub assembly nozzle body 30C. Therefore, downsizing can be achieved through the close arrangement of the sub assembly nozzle body 30 </ b> C and the nozzle drive unit 80.

  In the second embodiment, the motor 81 is a double-axis motor and the first and second clutches are arranged on the left and right sides of the motor. However, the second embodiment can be modified as follows. FIG. 26 is a schematic diagram schematically showing the configuration of a nozzle drive unit 80A in a modification of the second embodiment. As shown in the figure, the nozzle drive unit 80A is arranged so that the rotation shaft 81a of the motor 81A is orthogonal to the output shafts 82a and 83a of the first clutch 82 and the second clutch 83, and the rotation shaft 81a and each output shaft. Are selectively connected with a gear. Even in this nozzle drive unit 80A, since the motor 81A, the first clutch 82, and the second clutch 83 can be integrated and incorporated under the sub assembly nozzle body 30C, the size is small as in the case of the nozzle drive unit 80. Can be achieved.

  Next, the sanitary washing device of the third embodiment will be described. FIG. 27 is a schematic perspective view of a nozzle drive unit 90 included in the sanitary washing device of the third embodiment. As shown in the figure, the nozzle drive unit 90 is integrated with the sub assembly nozzle body 30C, and has the following configuration in order to advance and retract the first nozzle 31C and the second nozzle 32C, respectively.

  The nozzle drive unit 90 includes a motor 91 incorporated below the sub assembly nozzle body 30C, a drive pulley 92 directly connected to the motor output shaft, two driven pulleys 93 and 94, a tension pulley 95, and a hook on these pulleys. Timing belt 96 is provided. The motor 91 is a stepping motor that can rotate forward and backward, and is rotationally controlled by a control unit (not shown). The timing belt 96 forms a linear track along the advancing / retreating direction of the first nozzle 31C and the second nozzle 32C between the driven pulleys 93 and 94, and between the driven pulley 94 and the tension pulley 95, and the motor rotation is performed by the nozzle. Convert to advance / retreat operation. The timing belt 96 has a first nozzle advancement / retraction pressing piece 97 and a second nozzle advancement / retraction pressing piece 98 as shown in each of the two linear trajectory ranges. Accordingly, the pressing pieces 97 and 98 reciprocate in the linear track range as the timing belt 96 rotates forward and backward. In this case, the pressing pieces 97 and 98 are provided substantially at the center of each linear trajectory range.

  The first nozzle 31C and the second nozzle 32C are connected to springs 99a and 99b, respectively, on the rear end side. For this reason, both the nozzles always receive the urging force of the spring toward the illustrated standby position TP, and are positioned at the standby position TP by a stopper (not illustrated). Further, both nozzles have locking pieces 100a and 100b protruding to the timing belt 96 side. When the pressing pieces 97 and 98 of the timing belt 96 come into contact with each other, both the locking pieces transmit the driving force of the timing belt 96 to the first and second nozzles. Therefore, the first nozzle 31C and the second nozzle 32C advance and retreat individually as follows according to the reciprocating motion of the pressing pieces 97 and 98 along the linear track.

  When the anal washing button is operated, the control unit drives the motor 91 to rotate in the M direction in the drawing. The rotational drive amount at this time is such that the first nozzle 31C at the standby position TP reaches its cleaning position (anal cleaning position KP (see FIG. 22)). As a result, the timing belt 96 rotates counterclockwise, and this operation is transmitted to the first nozzle 31C via the pressing piece 97 and the locking piece 100a in contact therewith. At this time, since the other pressing piece 98 moves to the side away from the locking piece 100b, the belt driving force is not transmitted to the second nozzle 32C. Therefore, the first nozzle 31C advances from the standby position TP alone to the anal cleaning position KP against the urging force of the spring 99a. Then, cleaning water is supplied to the first nozzle 31C, and anal cleaning is performed. Thereafter, when the stop button is operated, the control unit drives the motor 91 in the reverse direction in the N direction in the figure by the amount of rotational drive described above, and returns the motor 91 to the origin where the nozzle is located at the standby position TP. During the reverse rotation of the motor during this period, the pressing piece 97 does not press the locking piece 100a, so the first nozzle 31C does not return to the standby position TP by the timing belt 96. However, the first nozzle 31C receives the urging force of the spring 99a and returns to the standby position TP.

  On the other hand, when the bidet washing button is operated while the motor 91 is at the origin, the control unit rotates the motor 91 in the N direction. The rotational drive amount at this time is such that the second nozzle 32C at the standby position TP reaches its cleaning position (the bidet cleaning position BP (see FIG. 23)). As a result, the timing belt 96 rotates clockwise, and this operation is transmitted to the second nozzle 32C via the pressing piece 98 and the locking piece 100b in contact therewith. At this time, since the other pressing piece 97 moves to the side away from the locking piece 100a, the belt driving force is not transmitted to the first nozzle 31C. Therefore, the second nozzle 32C advances from the standby position TP alone to the bidet cleaning position BP against the biasing force of the spring 99b, and bidet cleaning is performed. Thereafter, when the stop button is operated, the control unit drives the motor 91 to rotate in the reverse direction in the M direction by the amount of rotational drive described above, and returns the motor 91 to the origin. During this time, the second nozzle 32C returns to the standby position TP under the urging force of the spring 99b, as in the case of the first nozzle 31C.

  According to the sanitary washing device of the third embodiment described above, the effects (such as downsizing and relief of anxiety during female local washing) described above by the sub assembly nozzle body 30C can be achieved. Further, in the sanitary washing apparatus of the third embodiment, the first nozzle 31C and the second nozzle 32C are advanced to the respective washing positions by forward and reverse rotation of the motor 91, and the nozzles are returned to the standby position TP by springs 99a and 99c. To do. For this reason, only a single nozzle drive system including a single motor, a timing belt, and the like is required, and a clutch for switching rotation transmission of the motor is not required. Therefore, this nozzle drive system can be disposed close to the sub assembly nozzle body 30C, and the size of the apparatus can be reduced through this.

  Next, a sanitary washing device according to a fourth embodiment will be described. FIG. 28 is a schematic perspective view of the nozzle drive unit 110 included in the sanitary washing device of the fourth embodiment. FIG. 29 is a side view of the first nozzle 31C and the second nozzle 32C in plan view. FIG. 30 is an explanatory diagram for explaining the advance / retreat state of the second nozzle 32C, and FIG. 31 is a perspective view for explaining the advance / retreat state of the second nozzle 32C. As shown in the figure, the nozzle drive unit 110 is integrated with the sub assembly nozzle body 30C, and has the following configuration to advance and retract the first nozzle 31C and the second nozzle 32C during local cleaning.

  The nozzle drive unit 110 includes a motor 111 incorporated below the sub assembly nozzle body 30C, a drive pulley 112 directly connected to the motor output shaft, two driven pulleys 113 and 114, and a timing belt 115 applied to these pulleys. Have In this case, one of the driven pulleys also acts as a tension pulley. The motor 111 is a stepping motor that can rotate forward and backward, and is rotationally controlled by a control unit (not shown). The timing belt 115 forms a linear trajectory along the advancing / retreating direction of the first nozzle 31C and the second nozzle 32C between the driven pulleys 113, 114, and converts the motor rotation into the advancing / retreating operation of the nozzle. The timing belt 115 is connected and fixed to the first nozzle 31C by a latch 116. That is, the rotation operation of the timing belt 115 is directly transmitted as a linear operation only to the first nozzle 31C.

  The second nozzle 32C has a rear end portion 117 extending rearward from the first nozzle 31C. On the upper surface of the rear end portion 117, a heart cam groove 119 into which the guide pin 118 at the rear end of the first nozzle 31C enters is formed. The guide pin 118 is made of spring steel. The heart cam groove 119 is formed so as to engage or disengage the first nozzle 31C and the second nozzle 32C according to the position of the guide pin 118 in the groove. Details thereof will be described later. In addition, the second nozzle 32 </ b> C is also formed with a groove 120 having a linear locus continuous to the heart cam groove 119. Note that the movement of the second nozzle 32C is forcibly suppressed by a stopper (not shown) so as not to move rearward from the illustrated standby position TP.

  Next, the state of nozzle advancement / retraction by the nozzle drive unit 110 will be described with reference to FIGS. 29 to 31. When the cleaning button is not operated, both the first nozzle 31C and the second nozzle 32C are at the standby position TP. Further, the guide pin 118 has its tip 118a positioned at the base (origin position G0) of the heart cam groove 119 shown in FIG. Now, when the anal washing button is operated, the control unit drives the motor 111 to rotate in the M direction shown in FIG. The rotational drive amount at this time is such that the first nozzle 31C at the standby position TP reaches its cleaning position (anal cleaning position KP (see FIG. 22)). As a result, the timing belt 115 rotates counterclockwise, and this operation is transmitted to the first nozzle 31C via the latch 116. At this time, since the guide pin 118 can move to the left along the groove 120, the first nozzle 31C advances from the standby position TP alone to the anal cleaning position KP. That is, the guide pin 118 in this case is only located in the groove 120 that coincides with the forward / backward direction of the first nozzle 31C, and does not engage the first nozzle 31C and the second nozzle 32C. Then, cleaning water is supplied to the first nozzle 31C, and anal cleaning is performed. Thereafter, when the stop button is operated, the control unit drives the motor 111 to rotate in the N direction in the reverse direction by the amount of rotational drive described above, and returns the motor 111 to the origin. At this time, the guide pin 118 also returns to the origin position G0.

  On the other hand, when the bidet washing button is operated, the control unit drives the motor 111 to rotate in the N direction. The cam groove bottom of the heart cam groove 119 is gradually deepened along the forward path K1 from the origin position G0 to the front of the engagement position G1 shown in FIG. Can move to the right in the figure. Therefore, when the motor is driven as described above, the first nozzle 31C moves to the right independently. The rotational drive amount at this time is an amount by which the first nozzle 31C moves as long as the tip 118a of the guide pin 118 is fitted into the engagement position G1 where the groove depth is deeper than the end of the forward path K1. In addition, as shown in the figure, the jet nozzle 37C of the second nozzle 32C is exposed to the outside by the rightward movement of the first nozzle 31C.

  The cam groove bottom of the return path K2 of the cam groove connected to the engagement position G1 is shallower than the engagement position G1 at the return path starting point, and the cam groove bottom gradually becomes deeper toward the origin position G0. Therefore, when the tip 118a of the guide pin 118 is fitted into the engagement position G1, the first nozzle 31C and the second nozzle 32C are engaged via the guide pin 118. For this reason, thereafter, both nozzles can move (advance and retreat) in the left-right direction in the figure as a unit.

  When the nozzles are thus engaged and integrated, the control unit drives the motor 111 to rotate in the M direction, so that the second nozzle 32C moves from the standby position TP together with the first nozzle 31C as shown in FIG. Advances to the anal cleaning position KP. Then, cleaning water is supplied to the first nozzle 31C, and anal cleaning is performed. In this case, at the end of the return path K2 of the heart cam groove 119, the cam groove bottom is made higher than the starting point (origin position G0) of the forward path K1, so that the guide pin 118 follows the groove without receiving resistance on the return path K2. It moves to the left along the groove 120 from the origin position G0.

  Next, when the stop button is operated, the control unit controls the motor 111 step by step as follows. First, the control unit drives the motor 111 in the reverse direction in the N direction so that the nozzle can be returned. As a result, the first nozzle 31C and the second nozzle 32C are retracted until the second nozzle 32C returns to the standby position TP while being engaged and integrated. At this time, the motor 111 is driven and controlled so that the second nozzle 32C exceeds the standby position TP by a predetermined distance. However, since the second nozzle 32C does not move backward beyond the standby position TP by the stopper as described above, it remains at this standby position TP. However, since the driving force of the motor is transmitted through the timing belt 115 to the first nozzle 31C, the first nozzle 31C remains at the predetermined distance after the second nozzle 32C remains at the standby position TP. Only retreat. Then, the guide pin 118 rides over the step of the cam groove bottom between the engagement position G1 and the starting point of the return path K2 and rides on the return path K2.

  Thereafter, the control unit rotationally drives the motor 111 in the M direction in order to return the first nozzle 31C to the standby position TP. That is, the control unit controls the motor 111 so that the first nozzle 31C moves to the left by an addition distance between the predetermined distance and the distance between the engagement position G1 and the origin position G0. As a result, the first nozzle 31C accurately returns to the standby position TP.

  The above-described sanitary washing apparatus of the fourth embodiment can also achieve the effects (such as downsizing and relief of anxiety during female local washing) by the sub assembly nozzle body 30C. In the sanitary washing device of the fourth embodiment, the first nozzle 31C and the second nozzle 32C are engaged and integrated via the guide pin 118 and the heart cam groove 119, and the first nozzle 31C is moved forward and backward. The second nozzle 32C can be advanced and retracted by the drive unit 110. For this reason, only a single nozzle drive system (nozzle drive unit 110) including a single motor, a timing belt, and the like is required, and a clutch for switching rotation transmission of the motor is not required. In addition, since the first and second nozzles can be arranged in parallel so that they can be engaged and integrated via the guide pin 118 and the heart cam groove 119, the nozzle drive unit 110 can be arranged close to both nozzles. Therefore, the size of the device can be reduced through these.

  Next, a sanitary washing device according to a fifth embodiment will be described. FIG. 32 is a schematic perspective view of the nozzle drive unit 130 included in the sanitary washing device of the fifth embodiment, and FIG. 33 is a schematic view schematically illustrating the configuration of the water supply pressure drive clutch 140 included in the nozzle drive unit 130. . As shown in the figure, the nozzle drive unit 130 is integrated with the sub assembly nozzle body 30C, and has the following configuration in order to advance and retract the first nozzle 31C and the second nozzle 32C individually during local cleaning. Have.

  The nozzle drive unit 130 includes a motor 131 incorporated below the sub assembly nozzle body 30C, a drive pulley 132 directly connected to the motor output shaft, two driven pulleys 133 and 134, a tension pulley 135, and a hook on these pulleys. Timing belt 136 is provided. The motor 131 is a stepping motor that can rotate forward and reverse, and is rotationally controlled by a control unit (not shown). The timing belt 136 forms a linear track along the advancing / retreating direction of the first nozzle 31C and the second nozzle 32C between the driven pulleys 133, 134, and converts the motor rotation into the advancing / retreating operation of the nozzle. The timing belt 136 selectively supplies either the first nozzle 31C or the second nozzle 32C with motor rotation as a nozzle advance / retreat operation in accordance with the supply state of the wash water to both nozzles. 140.

  The water supply pressure drive clutch 140 is connected to a water supply unit 150 that warms the wash water and supplies water to the nozzle, and includes a first clutch portion 141 for transmitting the motor rotation to the first nozzle 31C, and a second nozzle. A second clutch portion 142 for transmitting to 32C is provided. The water supply unit 150 is controlled by the control unit and is supplied to the water supply destination nozzle (first nozzle 31C or the second nozzle 32C) corresponding to the operation button, and to the water supply pressure driving clutch 140 corresponding to the water supply destination nozzle. To introduce water supply pressure. That is, when the anal cleaning button is operated, the water supply unit 150 supplies cleaning water to the first clutch portion 141 to introduce the supply water pressure into the clutch portion, and the first nozzle 31C reaches the anal cleaning position KP. After that, the cleaning water is supplied to this nozzle. On the other hand, in the case of the bidet cleaning button, the water supply pressure is introduced into the second clutch portion 142, and the cleaning water is supplied to this nozzle after the second nozzle 32C reaches the bidet cleaning position BP.

  As shown in FIG. 33, the first clutch portion 141 is disposed opposite to the engagement shaft 143 protruding from the side of the first nozzle 31C, and a guide portion 141b, a clutch body 141c, a spring 141d, and water supply are provided in the clutch housing 141a. A tube 141e is provided. The guide portion 141b is disposed in contact with the left side surface of the engagement shaft 143, and slides and guides the clutch body 141c toward the nozzle. The clutch body 141c slides forward by receiving the supply pressure of the cleaning water from a water supply pipe 141e fixed on the end face thereof in a watertight manner, and after the supply water pressure is released, returns to the original position shown in the figure by a spring 141d. Therefore, when the cleaning water supply pressure is applied to the first clutch portion 141, the first clutch portion 141 brings the guide portion 141b and the clutch body 141c into contact with both side surfaces of the engagement shaft 143 and engages with the first nozzle 31C. To do. Therefore, the motor rotation is transmitted to the first nozzle 31C via the first clutch portion 141. Similarly to the first clutch portion 141, the second clutch portion 142 is engaged with the engagement shaft 144 of the second nozzle 32C and transmits the motor rotation. In this case, the supply water pressure of the cleaning water to both clutch portions is selectively performed by the water supply unit 150 as described above, so that the motor rotation is selectively applied to either the first nozzle 31C or the second nozzle 32C. Communicated. Therefore, each nozzle advances and retreats individually as follows.

  When the anus cleaning button is operated, the water supply pressure is guided to the first clutch portion 141 by the water supply unit 150 as described above, and the clutch body 141c moves forward. As a result, the first nozzle 31C receives transmission of motor rotation. Next, the control unit rotationally drives the motor 131 in the M direction in the figure. The rotational drive amount at this time is such that the first nozzle 31C at the standby position TP reaches its cleaning position (anal cleaning position KP (see FIG. 22)). Accordingly, the timing belt 136 rotates counterclockwise, and this operation is transmitted to the first nozzle 31C via the engagement shaft 143 and the clutch body 141c contacting the right side surface thereof. At this time, in the second clutch portion 142, no feed water pressure is applied and the clutch body 142c is not in contact with the engagement shaft, so that the belt driving force is not transmitted to the second nozzle 32C. Therefore, the first nozzle 31C advances from the standby position TP alone to the anal cleaning position KP. Then, wash water is supplied from the water supply unit 150 to the first nozzle 31C, and anal cleaning is performed. Thereafter, if the stop button is operated, the cleaning water supply from the water supply unit 150 is stopped, so that the clutch body 141c returns to the original position, and the guide shaft 141b is provided only on the left side surface of the engagement shaft 143. Touch. Further, the control unit drives the motor 131 in the reverse direction in the N direction in the figure by the amount of rotational drive described above. In this case, the belt driving operation is transmitted to the first nozzle 31C via the engaging shaft 143 and the guide portion 141b contacting the left side surface thereof, so that the first nozzle 31C returns to the standby position TP.

  On the other hand, when the bidet washing button is operated when the motor 131 is at the above-described origin, the introduction destination of the water supply pressure by the water supply unit 150 becomes the second clutch portion 142. Therefore, the second nozzle 32C receives the motor rotation. Thereafter, since the control unit rotationally drives the motor 131 in the M direction, the second nozzle 32C at the standby position TP advances independently to the cleaning position (the bidet cleaning position BP (see FIG. 23)). After the stop button is operated, the second nozzle 32C returns to the standby position TP as in the case of the first nozzle 31C.

  According to the sanitary washing device of the fifth embodiment described above, the above-described effects (such as downsizing and relief of anxiety during female local washing) by the sub assembly nozzle body 30C can be achieved. Further, in the sanitary washing device of the fifth embodiment, when the first nozzle 31C and the second nozzle 32C are individually driven forward and backward to the washing position, the motor output from the nozzle drive unit 80 is used as the washing water supply water pressure. It is selectively transmitted by a feed water pressure driving clutch 140 as a driving force. For this reason, since a special drive source for output transmission switching is not required, the structure can be simplified, and the size of the apparatus can be reduced through this.

  In each of the sanitary washing apparatuses of the second to fifth embodiments described above, the case where the sub assembly nozzle body 30C is used has been described as an example. However, the present invention is not limited to the sub assembly nozzle body 30C, and FIG. 1, FIG. 12, or FIG. The sub-assembly nozzle body 30 shown in FIG. 14, the sub-assembly nozzle body 30A of FIG. 14, and the sub-assembly nozzle body 30B of FIG. 19 can also be used. FIG. 34 shows a schematic perspective view of the nozzle drive unit 110A in the sanitary washing device of the fourth embodiment using the sub assembly nozzle body 30. FIG. In this nozzle drive unit 110A, a heart cam groove 119 is formed in the inner peripheral wall of the rear end of the second nozzle 32 positioned outside, and a guide pin 118 is installed at the rear end of the first nozzle 31 accommodated therein. Then, the timing belt 115 and the first nozzle 31 may be connected by the latch 116 so that the motor rotation is transmitted only to the first nozzle 31. In this case, if the first nozzle 31 is an anal nozzle, the first nozzle 31 is driven forward and backward independently during anus cleaning as described in the fourth embodiment. During bidet cleaning, both nozzles are engaged with the first nozzle 31 retracted in the second nozzle 32, and the second nozzle 32 is advanced and retracted together with the first nozzle 31. In this way, at the time of bidet cleaning, the second nozzle 32 advances and retreats with the first nozzle 31 not visible from the tip of the second nozzle 32. That is, it is possible to give the user an impression that the second nozzle 32 that is a bidet nozzle advances and retreats alone. When the second nozzle 32 is an anal nozzle and the first nozzle 31 is a bidet nozzle, the second nozzle 32 is advanced and retracted together with the first nozzle 31 during anus cleaning, and the first nozzle 31 is independently advanced and retracted during bidet cleaning. And the impression that the 2nd nozzle 32 which is an anal nozzle advances / retreats independently can be given to a user.

  Here, modified examples of the second to fifth embodiments will be described. In this modification, the nozzles (first nozzle and second nozzle) at the respective cleaning positions can be adjusted along the X direction along the advancing / retreating direction and the Y direction perpendicular thereto. FIG. 35 is a schematic perspective view showing a sanitary washing device 40A according to a modification of the second to fifth embodiments together with a toilet bowl, FIG. 36 is a block diagram showing the configuration of this modification, and FIG. 37 shows the cleaning position of the nozzle. 38 is a schematic configuration diagram of the nozzle sub drive unit 170 that adjusts in the left-right direction of the toilet bowl, and FIG. 38 is an explanatory diagram illustrating how the cleaning position is adjusted by the nozzle sub drive unit 170.

  As illustrated, the sanitary washing device 40A according to the modification includes a nozzle unit 50, a nozzle drive unit 54, a control unit 58, and the like, as with the sanitary washing device 40. A nozzle XY adjustment operation unit 160 is provided in front of the side sleeve portion of the main body cover 46. The nozzle XY adjustment operation section 160 is provided with a joystick 161 that is tilted in the X direction (nozzle longitudinal direction) and the Y direction (toilet lateral direction) shown in FIG. The joystick 161 is designed to be easily gripped by a user seated on the toilet seat, and at the tip thereof is a trigger that is pressed with the thumb when adjusting the amount of flushing water (water force) during local washing. 162 is provided.

  The nozzle XY adjustment operation unit 160 is connected to the control unit 58 as shown in FIG. The nozzle XY adjustment operation unit 160 includes an X-direction tilt operation amount of the joystick 161 (the nozzle front direction is the + X direction), a Y-direction tilt operation amount (the nozzle XY adjustment operation unit 160 side is the + Y direction), and the trigger 162. Each pressing operation amount is converted into an electrical signal and output. The control unit 58 inputs a signal from the nozzle XY adjustment operation unit 160 and drives and controls the nozzle drive unit 54 and the nozzle sub drive unit 170 to adjust the cleaning position of the nozzle. Further, the water supply unit 52 is controlled to adjust the water flow. Details thereof will be described later.

  The nozzle sub drive unit 170 has the following configuration in order to enable the Y direction adjustment of the cleaning position by the nozzle XY adjustment operation unit 160 described above. As shown in FIG. 37, the nozzle sub drive unit 170 is disposed on the main body base 42 so as to support the nozzle unit 50 integrated with the nozzle drive unit 54 from below, and the nozzle unit support unit 171 and the Y direction adjustment are arranged. A driving source motor 172 is included. The nozzle unit support part 171 has a recess 173 on the toilet bowl part 41a side. The nozzle unit 50 has a support plate 51 extending downward, and a support piece 51 a having a spherical lower end is fitted into the recess 173. Therefore, the nozzle sub drive unit 170 supports the nozzle unit 50 from below so as to be rotatable along the direction intersecting the paper surface of FIG. Even on the rear side of the support plate 51, the nozzle unit 50 is supported by a support block (not shown).

  A gear 51b is formed at the rear lower end portion of the support plate 51 with a reference pitch circle centered on the support piece 51a as shown in the G direction arrow in the figure. The motor 172 is a stepping motor that rotates forward and backward, and rotationally drives a gear plate 172c having a drive gear portion 172a that meshes with the gear 51b. Therefore, when the motor 172 rotates forward and backward, as shown in FIG. 38, the first nozzle 31 at the anus cleaning position KP is swung left and right around the support piece 51a to change its position. Adjustments are made.

  Next, the state of local cleaning in this modification will be described. Even in this modified example, when the anus cleaning button is operated, the anus cleaning is performed by moving the nozzle to the anus cleaning position KP and supplying the cleaning water as in the above embodiment. . However, during this cleaning operation, in this modification, the control unit 58 detects the operation status of the joystick 161 and the trigger 162 every predetermined time, and according to the result, the cleaning position adjustment and the water flow are performed as follows. Make adjustments.

  It is assumed that the joystick 161 is operated in the + X direction (see FIG. 35) when the irrigation is performed by ejecting the washing water at the regular anal washing position KP shown in FIGS. The control unit 58 drives and controls the nozzle drive unit 54 in accordance with the stick operation amount, and moves the first nozzle 31 forward to the anal cleaning position KP (+ X) shown in FIG. Thereby, the 1st nozzle 31 spouts wash water at the anal cleaning position KP (+ X) after this movement, and continues anal cleaning. The same applies when the joystick 161 is operated in the -X direction. If the joystick 161 is operated in the + Y direction (see FIG. 35), the control unit 58 controls the nozzle sub drive unit 170 in accordance with the stick operation amount, and the first nozzle 31 is cleaned as shown in FIG. Move to position KP (+ Y). Thereby, the 1st nozzle 31 spouts wash water at the anal cleaning position KP (+ Y) after this movement, and continues anal cleaning. The same applies when the joystick 161 is operated in the -Y direction. The same applies when the bidet cleaning button is operated to perform bidet cleaning.

  On the other hand, when the trigger 162 is pressed during the local cleaning, the control unit 58 controls the water supply unit 52 according to the trigger operation amount and adjusts the cleaning water supply amount to the first nozzle 31 step by step. To do. Thereby, the washing water flow is adjusted. Note that the control unit 58 determines whether the adjustment of the water force is increased or decreased according to the state of the pressing operation of the trigger 162. For example, if the trigger 162 is pressed for a long time, the water supply amount is adjusted to increase by one step, assuming that the adjustment is increasing. If the trigger 162 is repeatedly pressed twice in a short time, the water supply amount is adjusted to decrease by one step, assuming that the adjustment is a decrease adjustment.

  The modification described above is preferable because the local cleaning position can be finely adjusted in the nozzle front-rear direction and the left-right direction. In addition, since the joystick 161 is provided at the side of the toilet bowl where the hand lowered by the user seated on the toilet seat can reach naturally, the position can be easily adjusted without taking an unreasonable posture. Further, the water flow can be easily adjusted by the trigger 162.

  In this modification, the tilting operation of the joystick 161 is used to adjust the cleaning position. However, as described below, a cleaning button (anus cleaning button, bidet cleaning button) for instructing cleaning can be used. That is, the control unit 58 detects the presence / absence of the tilt operation of the joystick 161 every predetermined time when the seating sensor (not shown) detects the seating of the user. If the operation of tilting the joystick 161 in the + X direction is performed before the cleaning button is operated, the nozzle is advanced to the cleaning position and the cleaning water is supplied with this operation, and the local cleaning is started. In this way, local cleaning can be easily started with the joystick 161. In addition, when the joystick 161 is tilted twice in the + X direction within a short time, the local cleaning can be started using this as a trigger. In this way, an erroneous operation due to mischief or the like of the child can be avoided more effectively.

  This modification can be further modified as follows. 39 is a perspective view of a main part of a nozzle XY adjustment operation unit 160 having a grind pad 180 instead of the joystick 161, and FIG. 40 is a perspective view of a main part of the nozzle XY adjustment operation unit 160 having an LCD touch panel 182.

  The grind pad 180 shown in FIG. 39 is configured to detect the pressing pressure at the fingertip and the fingertip moving direction on the pad surface when the fingertip is placed on the pad surface. In this case, a pressure-sensitive element that converts pressure into an electrical signal is used for pressure detection, and the detection result is output to the control unit 58. The control unit 58 controls the water supply unit 52 in accordance with this result, and adjusts the washing water flow. That is, in place of the operation of the trigger 162, the water force is adjusted by the degree of pressing on the pad surface. For detecting the fingertip movement direction, a so-called matrix switch is used in which switching devices using the capacitance of the human body are arranged in a matrix on the pad surface. Then, the movement directions in the + X direction, the −X direction, the + Y direction, and the −Y direction from the current fingertip position are output to the control unit 58 as electrical signals. The control unit 58 drives and controls the nozzle drive unit 54 or the nozzle sub drive unit 170 in accordance with the fingertip movement direction, and adjusts the local cleaning position in the nozzle front-rear direction or the left-right direction. That is, in place of the tilt operation of the joystick 161, the cleaning position is adjusted according to the fingertip movement direction on the pad surface. According to the grind pad 180, the movement width at that time can be detected along with the movement direction of the fingertip. Therefore, the adjustment amount in the left-right direction of the local cleaning position is determined according to the degree of the movement width. You can also adjust left and right. Further, according to this grind pad 180, it is possible to detect that the fingertip is continuously moved back and forth or left and right. Therefore, when such continuous movement occurs, the nozzle is reciprocated back and forth or left and right. It is also possible to carry out local cleaning while moving. Further, if the fingertip is placed on the grind pad 180 prior to the operation of the anal washing button, the local washing can be started as a trigger for placing the fingertip. In this case, if the fingertip placement on the grind pad 180 is repeated twice in a short time, it is preferable to start the local cleaning from the viewpoint of avoiding an erroneous operation.

  The LCD touch panel 182 shown in FIG. 40 detects the pressing pressure at the fingertip, the moving direction of the fingertip, and the moving width thereof using a pressure sensitive element or a matrix switch in the same manner as the grind pad 180, and outputs the detection result to the control unit 58. Therefore, similarly to the grind pad 180, it is possible to adjust the cleaning water flow and the front / rear / left / right adjustment of the local cleaning position. Further, the local cleaning can be started by placing the fingertip on the panel surface. Further, the LCD touch panel 182 can display an image on the panel surface, and thus has the following advantages.

  Prior to the start of the local cleaning through the operation of the cleaning button and the fingertip placement on the panel surface, or during the local cleaning, the anal cleaning position KP or the bidet cleaning position BP can be displayed on the panel surface. For example, the cleaning position can be point-displayed with a predetermined color on the panel surface. Therefore, the user can indirectly confirm the local cleaning position via the display point, and the cleaning position can be adjusted by placing the fingertip on the front, back, left and right of the display point. In addition to the point display of the cleaning position, the outline of the human body around the cleaning part can be roughly displayed on the panel surface. In this way, although it is indirect, the cleaning position adjustment can be executed after recognizing the relationship between the human body and the cleaning position.

  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.

For example, the bidet nozzle can be made by coating fine particles of a 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 removed quickly and reliably by the washing water applied during self-cleaning. Is further preferred. Examples of the photocatalyst include TiO ₂ , ZnO, SnO _{2 and the} like, and TiO ₂ is preferable in terms of easy procurement.
