Description

  The present invention relates to a sanitary washing device that is used on a toilet bowl.

  More particularly, the present invention relates to a sanitary washing apparatus having a nozzle washing unit for washing a local part or the like of a human body with a washing nozzle, and further having a function of prohibiting a washing operation by the nozzle washing unit, and in particular, as an operation unit, a remote In a configuration that does not include a controller (remote control unit) and does not include a seating detector that detects the user's seating on the toilet seat, the cleaning operation that is prohibited is permitted by the user's operation. The present invention relates to a sanitary washing device.

  In the technical field of a sanitary washing apparatus for washing a local part of a human body, various techniques for preventing erroneous operation have been proposed. In general sanitary washing apparatuses, a safety mechanism is often provided in order to prevent erroneous operation of the operation unit. Specifically, for example, a configuration in which a seating sensor detects that a user has been seated on the toilet seat, and a cleaning operation or the like by a cleaning nozzle can be performed only when the user is in a seated state. In this configuration, since the cleaning water does not spout from the cleaning nozzle when the user is not seated, it is possible to prevent a situation where the cleaning water suddenly spouts due to an erroneous operation and wets the floor or clothes. .

  Furthermore, a technique that can deal with not only a general erroneous operation when the user is not seated but also an erroneous operation specific to an elderly person or a child has been proposed. For example, Patent Document 1 discloses that “a local cleaning device that has a hand operating unit and a remote control operating unit, and jets cleaning water from a nozzle by an operation on these operating units to clean a human body part”. A technique of providing a lock switch is disclosed.

  Specifically, when the user is an elderly person, when standing up from the toilet seat, the user touches the hand control unit to support the body, or when the user is a child, the user sits on the toilet seat. It is assumed that the user manipulates the hand operating unit carelessly. In such a situation, there is a possibility that a switch of the “hand control unit” or the like is erroneously pressed and an operation such as ejection of cleaning water is erroneously performed. In view of this, Patent Document 1 discloses a “local cleaning device” having a configuration in which an operation in the “hand operation unit” is not effective by operating a lock switch. Here, since the “local cleaning device” includes a remote control operation unit as an essential component, even if the operation of the “hand control unit” is locked, by operating the “remote control unit”, a predetermined operation can be performed. Operation (injection of cleaning water, etc.) can be performed.

  Further, in Patent Document 1, a “hand operation unit” is divided into a main operation unit and a sub operation unit, and only the operation of the main operation unit is disabled by providing a lock switch in the sub operation unit. Is also disclosed. The sub operation section may be provided with a lid and an operation switch that is not operated relatively frequently. As a result, the lid of the sub-operation unit is normally closed, so that the operation of the main operation unit is disabled, so that erroneous operation can be prevented and the main operation unit can be operated or operated only by the hand operation unit. It can be disabled.

  In addition, Patent Document 1 exemplifies a switch for adjusting the hot water temperature and the toilet seat temperature as a switch provided in the sub operation unit. Therefore, if the lid of the sub-operation part is closed, not only can the washing water be ejected due to an erroneous operation, but also the toilet seat temperature and the washing water temperature can be prevented from being erroneously changed.

  Patent Document 1 also discloses a configuration in which a dedicated lock switch is not provided. Specifically, a configuration that disables the operation of the main operation unit by continuously pressing a plurality of specific switches of the sub operation unit, for example, the hot water temperature adjustment and toilet seat temperature adjustment switches simultaneously for a predetermined time Is illustrated.

JP 09-219126 A

  By the way, it is known that detection failure such as undetected seating or false detection occurs in the seating sensor. For example, when the user's physique or weight is extremely small, such as an infant, the user's seating may not be detected. Further, depending on the seating position of the user, the seating sensor may not be able to detect the seating. Furthermore, for example, when the seating sensor is an optical sensor, it may be erroneously detected that the user is not seated because the window for emitting the detection light is dirty, even though the user is not seated. sell.

  If the seating of the user cannot be detected properly, the cleaning operation cannot be executed even if the user appropriately operates the operation unit. In addition, if an erroneous detection occurs in the seating sensor, there is a problem that the washing water is suddenly ejected due to an erroneous operation of the user as described above. That is, if the detection failure of the seating sensor occurs, the operability of the sanitary washing device is lowered.

  Here, the technique provided with the lock switch disclosed in Patent Document 1 is a technique for dealing with an erroneous operation unique to an elderly person or a child. Therefore, this technique is not a technique that can sufficiently cope with the decrease in the operability resulting from the detection failure of the seating sensor. In the technique disclosed in Patent Document 1, it is essential to provide a “remote control operation unit”. However, if the basic operation of the sanitary washing device is performed by the “remote control operation unit”, “ The need to provide a “hand control unit” is reduced. Therefore, the technique disclosed in Patent Document 1 cannot be applied to a sanitary washing apparatus having a configuration in which only the “hand operating unit” is provided without providing the “remote control operating unit”.

  Further, if the seating sensor is omitted from the sanitary washing apparatus, the detection failure of the seating sensor itself does not occur. However, if a seating sensor is not provided, it is not possible to prevent malfunctions caused by erroneous operations when the user is not seated. Therefore, the basic problem as described at the beginning of the background art described above cannot be achieved. I will come back.

  The present invention has been made to solve such a problem, and can effectively cope with a decrease in the operability of the cleaning function resulting from the detection failure of the seating sensor, and can reduce the number of members and An object of the present invention is to provide a sanitary washing apparatus that can reduce costs.

  In order to solve the above-described problem, a sanitary washing device according to the present invention includes a main body part that supports a toilet seat part on which a user is seated, and a nozzle cleaning that is provided in the main body part and performs a washing operation of ejecting washing water. A sanitary washing apparatus comprising: a unit, a fixed operation unit provided integrally with the main body unit and having a cleaning operation device for operating the nozzle cleaning unit; and a control unit for controlling at least the nozzle cleaning unit. The operation surface of the fixed operation unit is a push button type having a push surface, and a cleaning permission manipulator that inputs a permission command permitting the cleaning operation of the nozzle cleaning unit to the control unit, and the cleaning permission And an operation device guard member including a portion that is disposed adjacent to the operation device and protrudes from the operation surface to a position higher than the push surface, and the control unit receives the permission command from the cleaning permission operation device. If there is no input Even if the cleaning operation device is operated, the cleaning operation of the nozzle cleaning unit is prohibited. On the other hand, when the permission command is input from the cleaning permission operation device, the cleaning operation of the nozzle cleaning unit is performed. And the nozzle cleaning unit is controlled in accordance with an operation command from the cleaning operation device.

  According to the above configuration, in the sanitary washing apparatus operated by the fixed operation unit, the nozzle washing unit is “locked” so that the washing operation cannot be normally performed. It is released consciously by the user by operating. Moreover, the cleaning permission operation device is an operation device that is first operated by the user at the time of use, and therefore an operation device that is particularly likely to cause an erroneous operation. However, an operation device guard member is provided adjacent to the cleaning permission operation device. Therefore, the erroneous operation of the cleaning permission operating device itself can be effectively suppressed.

  Therefore, even if a seating detector (a seating sensor or the like) is not provided, it is possible to prevent problems due to an erroneous operation when the user is not seated. In addition, when the operation of the cleaning operation is necessary, the “lock” is released to enable the operation. Therefore, when the “lock” is maintained, a remote operation different from the fixed operation unit is performed. There is no need to be able to operate the cleaning operation with a unit (remote control unit).

  Therefore, the absence of the seating detector does not cause a detection failure of the seating detector itself, and the malfunction due to the absence of the seating detector does not occur, so the operability of the cleaning function is reduced. And good operability can be ensured. And since it becomes a structure which does not need to provide a seating detector and a remote control part, a number of members can be decreased and cost can be reduced.

  In the sanitary washing apparatus, in addition to the above configuration, a cleaning permission indicator for notifying that the cleaning operation is permitted is further provided on the operation surface of the fixed operation unit, and the control unit includes the cleaning unit. It is preferable that the cleaning permission indicator is further operated when the permission command is input from the permission operator.

  According to the above configuration, the cleaning permission indicator notifies the user that the “lock” of the nozzle cleaning unit has been intentionally released by the user. Therefore, it is possible to determine whether the “lock” is released or maintained while it is clear whether or not the cleaning operation can be performed. It is possible to more effectively prevent a malfunction due to an erroneous operation when the person is not seated.

  In the sanitary washing device, the specific configuration of the fixing operation unit is not particularly limited, for example, the fixing operation unit is from the right side as viewed from the user seated on the toilet seat in the main body, It is provided so as to extend to the front side as viewed from the user, and the upper surface of the fixed operation part is an operation surface for the user to perform an operation, and the cleaning permission operating device is the fixed operation The structure located in the edge part used as the front side seeing from the said user in the operation surface of a part can be mentioned as a preferable example.

  In the above configuration, the specific position of the operation device guard member provided in the fixed operation unit is not particularly limited. For example, the cleaning operation device is a rear side as viewed from the user in the cleaning permission operation device. The operation device guard member may be provided between the cleaning permission operation device and the cleaning operation device, and the operation device guard member may be configured to be the cleaning permission operation device. The structure provided adjacent to the said front side may be sufficient. In any configuration, the operation guard guard member can effectively suppress erroneous operation of the cleaning permission operation device itself.

  Further, in the sanitary washing device, the specific configuration of the operating device guard member itself is not particularly limited, and is disposed adjacent to the cleaning permission operating device and includes a portion higher than the pressing surface of the cleaning permission operating device. For example, as the operation device guard member, as a wall-shaped protrusion surrounding at least a part of the periphery of the cleaning permission operation device, the structure formed on the operation surface, or the cleaning A configuration formed on the operation surface can be given as a lid-like projection covering the upper surface of the permitted operation device. In any configuration, the operation guard guard member can effectively suppress erroneous operation of the cleaning permission operation device itself.

  As described above, according to the present invention, a sanitary washing apparatus that can effectively cope with a decrease in operability of the washing function resulting from the detection failure of the seating sensor, and can reduce the number of members and reduce the cost. Can be realized.

  Among the push buttons provided on the cleaning operation surface 52a, the cleaning stop switch 23a, the normal cleaning start switch 23b, the rhythm cleaning switch 23c, the bidet cleaning start switch 23d, the weak cleaning switch 23e, and the strong cleaning switch 23f are shown in FIG. This corresponds to the cleaning operation switch 23 in the control system shown in FIG. The normal cleaning start switch 23b and the bidet cleaning switch 23d are cleaning start switches that start the cleaning operation in the nozzle cleaning unit 57a. When the normal cleaning start switch 23b is pressed once, the nozzle cleaning unit 57a performs the normal cleaning operation under the control of the control unit 56, and when it is pressed once more, the nozzle cleaning unit 57a performs a normal cleaning move cleaning operation. Further, if the rhythm cleaning switch 23c is pressed while the normal cleaning operation is being performed, the nozzle cleaning unit 57a performs the rhythm cleaning under the control of the control unit 56. When the bidet cleaning switch 23d is pressed once, the nozzle cleaning unit 57a performs the bidet cleaning operation, and when it is pressed once more, the bidet cleaning move cleaning operation is performed.

  Each of the weak cleaning switch 23e and the strong cleaning switch 23f is a switch for adjusting the strength of nozzle cleaning, that is, the water pressure of hot water ejected from the cleaning nozzle 11. If the weak cleaning switch 23e is pressed, the control unit 56 If the set value of the cleaning strength is lowered and the strong cleaning switch 23f is pressed, the setting value of the cleaning strength is adjusted to be increased. The degree and stage of adjustment of the cleaning strength are appropriately set and are not particularly limited.

  Each push button provided on the basic operation surface 52b is used for operations other than the operation of the nozzle cleaning unit 57a and the operation of permitting or prohibiting the operation of the nozzle cleaning unit 57a, that is, power on / off, various temperature adjustments, etc. The basic operation of the cleaning device 50A is performed. If the hot water temperature adjustment switch 24 is pressed, the control unit 56 changes the set value of the hot water temperature. The degree of change is displayed on the hot water temperature display portion 27 a located on the front side of the hot water temperature adjustment switch 24. In the example illustrated in FIG. 3, the hot water temperature display unit 27a is configured by arranging three LEDs, and displays whether the changed hot water temperature is one of three set values from “low” to “high”. To do. Similarly, when the toilet seat temperature adjustment switch 25 is pressed, the control unit 56 changes the set value of the toilet seat temperature. The toilet seat temperature display unit 27b located on the side of the front side displays whether the changed toilet seat temperature is one of three set values from “low” to “high”.

  If the power saving switch 26a is pressed, the control unit 56 shifts to the power saving mode. In the power saving mode, if the sanitary washing device 50A is not used for a certain period of time, a power saving operation such as cutting off energization of some components of the sanitary washing device 50A is performed. If the automatic power cut-off switch 26b is pressed for 8 hours, the power is automatically cut off after 8 hours. If the earth leakage test switch 26c is pressed, an earth leakage test is performed to test whether or not the earth leakage breaker circuit incorporated in the sanitary washing device 50A functions effectively. The power-on display LED 27c displays the power-on status of the sanitary washing device 50A. For example, if it is lit in green, it is in the normal mode in which the sanitary washing device 50A is powered on and lights in orange. If it does, it will be displayed that it is in power saving mode. The automatic power-off operation display LED 27d displays that automatic power-off control is being performed.

  The power saving switch 26a, the 8-hour automatic power cut-off switch 26b, and the leakage test switch 26c are not shown in the control system shown in FIG. 2, but are basic operation switches for performing the basic operation of the sanitary washing apparatus 50A. Yes. The hot water temperature display unit 27a, the toilet seat temperature display unit 27b, the power-on display LED 27c, and the automatic power shut-off LED 27d are basic display units for displaying the state of the sanitary washing device 50A based on the operation of the basic operation switch. ing. The specific configurations of the basic operation switch and the basic display unit are not limited to these, and other operation switches or display units may be provided, or some operation switches or display units may not be provided. . Alternatively, the basic display unit may be configured such that one image display unit such as a liquid crystal display panel is provided collectively.

  The control of the sanitary washing device 50A including the fixed operation unit 52 having the above-described configuration will be specifically described together with the functions and operations of the operation permission switch 21 and the in-operation display LED 22a. In the flowchart of FIG. 5, in order to distinguish the control step from the user's action, the step is indicated by a single line frame, the user action is indicated by a double line frame, and the user's action is indicated. The correspondence between and steps is indicated by a broken line.

  First, if the power is supplied to the sanitary washing device 50A, as shown in the flowchart of FIG. 5, the control unit 56 controls to prohibit the nozzle driving operation in the nozzle washing unit 57a (step S101). ). If the entrance sensor 55 (see FIG. 1) detects that the user has entered the toilet room (step S102), the control unit 56 controls the toilet seat / toilet lid opening / closing unit so that the toilet lid 54 is moved. Open from the lying position to the standing position (step S103). Thereafter, after the user is seated (user's action U01), the nozzle drive permission determination unit 56a of the control unit 56 determines whether or not the operation permission switch 21 has been pressed and turned on (step S104). . In addition, since the sanitary washing device 50A according to the present embodiment does not include the seating sensor as described above, the control unit 56 does not determine whether or not the user is seated at this time.

  As shown in FIG. 2, the nozzle drive permission determination unit 56 a is configured such that operation commands are input from the operation permission switch 21 and the cleaning operation switch 23, and a command for permitting nozzle drive operation from the operation permission switch 21. If (permission command) is input, it is determined that the nozzle driving operation is permitted, and an operation command from the cleaning operation switch 23 is input to the calculation unit 56b. If the permission command is not input, the cleaning operation is performed. The operation command from the operation switch 23 is not input to the calculation unit 56b. Therefore, if the operation permission switch 21 is not turned on (NO in step S104), the control unit 56 maintains the control for prohibiting the nozzle drive operation (step S105), for example, among the cleaning operation operation switches 23. Even if the normal cleaning start switch 23b is turned on, the cleaning operation is controlled not to be performed (step S106). Thereafter, the nozzle drive permission determination unit 56a of the control unit 56 continues to determine whether or not the operation permission switch 21 has been turned ON again (return to step S104).

  By the way, the user defecates after taking the seat (act U01) (act U02). This defecation is usually performed after the seating until the operation permission switch 21 is turned on (ie, step). (During the determination of S104). This is because in the sanitary washing device 50A according to the present embodiment, the cleaning operation by the nozzle cleaning unit 57a is not performed unless the operation permission switch 21 is turned on. Therefore, after the defecation is completed, if the user turns on the operation permission switch 21 (YES in step S104), the nozzle drive permission determination unit 56a of the control unit 56 performs the determination to permit the nozzle drive operation, The calculation unit 56b performs a predetermined calculation to turn on the driving display LED 22a (step S107). As a result, the user is notified that the cleaning operation switch 23 is operable. In this state, for example, if the normal cleaning start switch 23b is turned ON, the normal cleaning start operation command is input to the calculation unit 56b via the nozzle drive permission determination unit 56a. Control is performed to cause the unit 57a to start the normal cleaning operation (step S108).

  Thereafter, if the cleaning stop switch 23a is operated, the control unit 56 performs control to stop the normal cleaning operation of the nozzle cleaning unit 57a (step S109). When the washing operation is completed, the user stands up from the toilet seat (user action U03), and the control unit 56 controls the toilet seat / toilet lid opening / closing unit to close the toilet lid 54 from the standing position to the lying down position (see FIG. Step S110). In step S110, the user may manually close the toilet lid 54 from the standing position to the lying position before the toilet lid 54 is closed from the standing position to the lying position by the control of the control unit 56.

  Thereafter, if the entrance sensor 55 (see FIG. 1) detects that the user has left the toilet room (step S111), the nozzle drive permission determination unit 56a of the control unit 56 operates the operation permission switch 21 to be turned off. It is determined whether or not it has been done (step S112).

  If the operation is OFF (YES in step S112), the control unit 56 shifts to control for prohibiting the nozzle drive operation in the nozzle cleaning unit 57a (step S113). If the operation is not OFF (NO in step S112). ), The control unit 56 performs control to automatically turn off the operation permission switch 21 after a predetermined time (for example, after 3 minutes) has elapsed (step S114), and thereafter prohibits nozzle drive operation in the nozzle cleaning unit 57a. The control shifts to (step S113). This completes the series of controls, but the controls are repeatedly executed while the power is on.

  As described above, in the sanitary washing device 50A according to the present embodiment, the nozzle cleaning unit 57a is “locked” (nozzle driving operation is prohibited) unless the operation permission switch 21 is operated. Therefore, the “lock” of the nozzle cleaning unit 57a is always intentionally released by the user (nozzle driving operation is permitted). Therefore, since it is possible for the user to determine whether to release or maintain the “lock” in a state where it is clear whether or not the cleaning operation is operable, the user can be determined without providing a seating sensor. It is possible to prevent a malfunction due to an erroneous operation when the is not seated. Therefore, since the detection failure of the seating sensor itself does not occur, the operability of the cleaning function does not deteriorate, and the seating sensor and the remote control operation unit are not provided, so the number of members is reduced and the cost is reduced. can do.

[Function of switch guard member]
Here, in the sanitary washing device 50A according to the present embodiment, as shown in FIGS. 3 and 4, a wall-like switch guard member 28a is provided on the washing operation surface 52a of the fixed operation unit 52. 3 and 4, the switch guard member 28a is formed in a flat wall shape that is a straight line when viewed from above, and the right side (sanitary washing device) of the operation permission switch 21 in the figure. It is located on the back side of 50A. In other words, the switch guard member 28a is disposed between the operation permission switch 21 and the cleaning stop switch 23a along the left-right direction of the sanitary cleaning device 50A so as to cross the longitudinal direction of the fixed operation unit 52. .

  As shown in the lower side view of FIG. 4, the switch guard member 28 a is a protruding member that protrudes upward from the cleaning operation surface 52 a, and its upper end is at a position higher than the pressing surface of the operation permission switch 21. ing.

  In the present embodiment, as described above, each operation switch including the operation permission switch 21 is a membrane switch. Although the membrane switch is also called a sheet switch and is a push button type switch, since the switch itself has a sheet shape, the unevenness of the operation surface can be reduced and the surface can be made substantially flat. In addition to this, since the switch itself has a sealed structure and is configured to be attached to the operation surface, it is excellent in waterproofness. If the operation surface is substantially flat, it is easy to clean and excellent waterproofness is an important characteristic for an electric product installed in an environment using water. Therefore, the membrane switch is a switch that can be preferably used particularly in the field of sanitary washing apparatus.

  However, as shown in the side view on the lower side of FIG. 4, all of the operation permission switch 21, the washing stop switch 23a, the normal washing start switch 23b, the rhythm washing switch 23c, and the bidet washing start switch 23d, which are membrane switches, The pressing surface does not protrude significantly from the cleaning operation surface 52a. Therefore, even if the user does not press the pressing surface so strongly, the switch may be turned ON or OFF. This is advantageous for the user because it allows simple switch operation, but it is also undesirable because it may cause an erroneous operation by touching the operation surface carelessly.

  In the present embodiment, the switch guard member 28a is provided in the vicinity of the operation permission switch 21 that is first operated by the user when the sanitary washing device 50A is used. Therefore, even if the user unintentionally places the palm on the driving permission switch 21, the entire pressing surface of the driving permission switch 21 is not pushed by the switch guard member 28a. As a result, an erroneous operation of the operation permission switch 21 can be avoided and the nozzle drive operation can be prevented from being inadvertently permitted.

  Here, in the present embodiment, the cleaning operation operation switch 23 such as the cleaning stop switch 23a, the normal cleaning start switch 23b, the rhythm cleaning switch 23c, and the bidet cleaning start switch 23d arranged on the cleaning operation surface 52a together with the operation permission switch 21. As long as the nozzle drive operation is not permitted by the operation permission switch 21, the operation is prohibited. In other words, unless the operation permission switch 21 is erroneously operated, the cleaning operation operation switches 23 cannot be erroneously operated.

  However, in view of the layout of the push buttons on the cleaning operation surface 52a, the operation permission switch 21 is often arranged adjacent to the cleaning operation switch 23 such as the cleaning stop switch 23a. Therefore, in the present embodiment, as shown in FIGS. 3 and 4, a flat wall-shaped switch guard member 28a is provided between the operation permission switch 21 and the cleaning stop switch 23a. As a result, it is possible to avoid the situation where the operation permission switch 21 and the cleaning operation switch 23 adjacent to each other are simultaneously pressed by the palm or the like, so that the possibility of erroneous operation can be further reduced. The specific type of the cleaning operation operation switch 23 adjacent to the operation permission switch 21 is not limited to the cleaning stop switch 23a, and can be appropriately changed depending on the layout of the push buttons on the cleaning operation surface 52a.

  In addition, the dimension etc. of the switch guard member 28a comprised as a wall-shaped protrusion are not specifically limited. For example, the height of the switch guard member 28 a from the operation surface only needs to be higher than the pressing surface of the operation permission switch 21. The specific height is appropriately set in consideration of the height of the pressing surface of the operation permission switch 21 from the operation surface. Similarly, the thickness of the switch guard member 28a is not particularly limited as long as the switch guard member 28a has such a thickness that the switch guard member 28a is not damaged or irreversibly deformed when pressed by a palm or the like from above. More preferably, the thickness may be such that when the switch guard member 28a is pressed with a palm or the like, the user can secure an area on the upper end side so as not to feel pain or the like on the palm or the like.

  Here, as shown in FIG. 4, the switch guard member 28 a is formed as a wall-like protrusion having the same height as a whole. However, the switch guard member 28 a is not limited to this, but rather than the pressing surface of the operation permission switch 21. If it is configured so that at least a high part is included and the function of the switch guard member 28a can be effectively exhibited, a part having a height equivalent to the pressing surface as viewed from the operation surface, or Needless to say, the lower portion may be included.

  The switch guard member 28a may be configured to be integrally formed with respect to the operation surface of the fixed operation unit 52, or may be manufactured as a separate member and attached to the operation surface later. May be.

[Modification]
In the present embodiment, the sanitary washing device 50 </ b> A includes the entrance sensor 55, but may be configured not to include the entrance sensor 55. With this configuration, control in which steps S102 and S111 are omitted in the flowchart shown in FIG. 5 is performed. Further, the sanitary washing device 50A includes the toilet seat / toilet lid opening / closing unit, but may be configured not to include the toilet seat / toilet lid opening / closing unit. With this configuration, control in which steps S103 and S110 are omitted in the flowchart shown in FIG. 5 is performed.

  Further, in the flowchart shown in FIG. 5, a configuration in which the operation permission switch 21 is automatically turned off at the same time as the step of stopping the cleaning operation in step S <b> 109 is completed may be employed. With this configuration, control in which steps S112 and S114 are omitted is performed. In this configuration, even if the operation permission switch 21 is not turned off, the control automatically shifts to prohibiting the nozzle drive operation. Of course, the operation permission switch 21 is turned off and the nozzle is actively activated. Driving operation can also be prohibited.

  Alternatively, after the step of stopping the cleaning operation is completed in step S109, the user may wish to perform cleaning again, and therefore step S108 may be performed again. Therefore, a configuration in which the operation permission switch 21 is automatically turned off on the basis that the step of stopping the cleaning operation in step S109 is repeated a plurality of times may be used. For example, after defecation, it is investigated in advance how much the average number of cleanings is within a range, and if the frequency of cleaning more than twice is low, if step S109 is repeated twice, automatically Control may be performed to prohibit the nozzle drive operation.

  In addition, the specific configuration of the fixed operation unit 52 is not particularly limited, and as described above, a configuration in which a single image display unit is provided as a basic display unit may be used. It also serves as the function of the middle display LED 22a, and therefore the operation display LED 22a may not be provided. That is, if the operation permission switch 21 is turned on, a message or graphic display indicating that the nozzle drive operation is permitted may be displayed on the image display unit. In this embodiment, each operation switch described above is configured as a button type membrane switch. However, depending on the type of operation switch, other push button type switches are used instead of flat membrane switches. Alternatively, instead of a push button type switch, a changeover switch may be employed, and if the image display unit is a touch panel, a configuration in which a push button is displayed on the touch panel may be used. A known switch may be used.

  Here, if the image display unit is a touch panel, not only each operation switch but also the operation permission switch 21 is a push button displayed on the touch panel, not a push button or a changeover switch having a mechanical or electrical configuration. be able to. However, because the switch guard member 28a is disposed adjacent to the operation permission switch 21, it is preferable that the operation permission switch 21 be an independent push button or a changeover switch.

  Further, in the present embodiment, the operation permission switch 21 is configured to permit the nozzle driving operation, but the present invention is not limited to this, and a cleaning permission operating device that can permit the cleaning operation by the nozzle cleaning unit 57a. Should just be provided. For example, if the sanitary washing device 50A has a “nozzle cleaning function”, although not shown in FIG. 3, a nozzle cleaning switch is provided on the basic operation surface 52b of the fixed operation unit 52, and the nozzle cleaning switch is When operated, the nozzle drive unit 12 drives the cleaning nozzle 11 to protrude from the main body 51. The protrusion of the cleaning nozzle 11 is not a “cleaning operation” for the purpose of cleaning the local area or the like, but a “nozzle cleaning operation” for the purpose of cleaning the cleaning nozzle 11. Wash water does not spout from the spout.

  If it is the said structure, since the control part 56 will have a washing | cleaning operation permission determination part instead of the nozzle drive permission determination part 56a, if the driving | operation permission switch 21 is operated, the washing | cleaning operation permission command will be calculated. This is input to the unit 56b. If the nozzle cleaning switch is operated, the calculation unit 56b controls the nozzle driving unit 12 to perform “nozzle driving” so that the cleaning nozzle 11 protrudes, but the permission command for the cleaning operation is input. There is no cleaning operation. Therefore, in this modified example, the operation permission switch 21 is not an permission for the nozzle driving operation but an operation switch for permitting the cleaning operation.

  As described above, according to the present invention, depending on the specific configuration of the fixed operation unit 52 and the control system, the operation switch that permits the prohibited cleaning operation may be provided as a result. The configuration is not limited to permitting driving. Note that if the driving of the cleaning nozzle 11 (nozzle driving) by the nozzle driving unit 12 is prohibited, the cleaning operation itself of the nozzle cleaning unit 57a is prohibited. Therefore, if the nozzle driving operation is permitted, the cleaning operation is permitted. Needless to say.

  Further, in the present embodiment, the switch guard member 28a is configured in a flat plate shape standing on the operation surface of the fixed operation unit 52, but of course not limited to this, for example, the thickness on the operation surface side. The tip end side thickness may be small, or the tip end side thickness may be increased.

  Furthermore, the switch guard member 28a does not necessarily have to be configured as a wall-like protrusion, and for example, may have a structure in which a plurality of protrusions are continuously arranged around the operation permission switch 21. That is, in the present invention, when the switch guard member 28a is placed on a part of the body (for example, a palm or the like) having an area larger than the fingertip from the upper side of the operation surface to the upper side of the operation permission switch 21, A protruding member that surrounds the periphery of the operation permission switch 21 may be provided so that the entire pressing surface of the operation permission switch 21 is not pressed.

  In addition, in the present invention, if the switch guard member 28a is included, the in-operation display LED 22a is not necessarily provided. This is because there is a low possibility that the operation permission switch 21 is erroneously operated by the switch guard member 28a. Of course, since it is desirable for the user to notify whether the nozzle drive operation is permitted or not, as described in the present embodiment, an in-operation display LED 22a or a display device having the same function is provided. It is particularly preferred that

  Furthermore, in the present embodiment, the fact that the nozzle drive operation is permitted is notified to the user by a light emitting body called a display LED 22a during operation, but of course, the present invention is not limited to this, and a known display device other than the light emitting body is known. (An image display device such as the touch panel) may be used, an alarm device that emits sound may be used instead of a display device, or a combination thereof may be used. That is, as long as it is possible to notify the user that the nozzle driving operation (or cleaning operation) is permitted, the means for performing the notification is not particularly limited. If the LED as in the present embodiment is used, since the size of the member is small, the fixing operation unit 52 can be made compact, and it is inexpensive and has low power consumption. Can be suppressed.

(Embodiment 2)
In the first embodiment, the operation permission switch 21 is provided at the front end of the fixed operation unit 52, and the switch guard member 28 a is provided adjacent to the rear side of the operation permission switch 21. The present invention is not limited to this configuration. This point will be specifically described with reference to FIG. FIG. 6 is a comparison between a plan view and a side view showing the configuration of the switch guard member 28b of the present embodiment.

  In the present embodiment, as shown in FIG. 6, the switch guard member 28 b is located on the front side of the operation permission switch 21. In this configuration, the switch guard member 28b is positioned at the front end of the fixed operation unit 52 extending from the front side to the rear side of the sanitary washing device 50A. Therefore, in the fixed operation unit 52, the most front switch Except for the guard member 28b, most of the operation surface is a continuous and substantially flat surface. If the substantially flat surface is wide, there is an advantage that the operation surface can be easily cleaned.

  The specific configuration of the switch guard member 28b is the same as that of the switch guard member 28a of the first embodiment, and a description thereof will be omitted.

  Here, when the user uses the sanitary washing device 50A, the position on the operation surface of the fixed operation unit 52 where the palm or the like is easily placed cannot be generally defined. For example, the sanitary washing device It varies depending on conditions such as a specific configuration of 50A, a configuration of a toilet room, a combination thereof, and the like. Therefore, when the user can easily touch the position near the cleaning stop switch 23a of the fixed operation unit 52, the configuration of the first embodiment may be adopted. When the user easily touches the front end of the fixed operation unit 52, The configuration of the first embodiment may be adopted.

(Embodiment 3)
In the first and second embodiments, the switch guard member 28a or 28b is configured as a flat wall-like protrusion adjacent to surround a part of the periphery of the operation permission switch 21, but the present invention is not limited to this. It is not limited to the configuration. This point will be specifically described with reference to FIG. FIG. 7 is a comparison between a plan view and a side view showing the configuration of the switch guard member 28c of the present embodiment.

  In the present embodiment, as shown in the top plan view of FIG. 7, the switch guard member 28 c is provided as a lid-shaped protrusion that covers most of the pressing surface of the operation permission switch 21. As shown in the side view on the lower side of FIG. 7, the user's fingertip F (two points in the figure) is provided between the inner surface side of the lid-type switch guard member 28 c and the pressing surface of the operation permission switch 21. A space is formed to the extent that the pressing surface of the operation permission switch 21 can be pushed in a state in which (shown by a chain line) is inserted. Thereby, it is possible to effectively prevent the pressing surface of the operation permission switch 21 from being inadvertently operated without impairing the operability of the operation permission switch 21.

  In the configuration shown in FIG. 7, the switch guard member 28 c is connected to the front end portion of the fixed operation unit 52 and covers the operation permission switch 21 from the front side toward the rear side, but the switch guard member 28 c is configured. Is not limited to this configuration, and may be configured to be connected to one side surface of the fixing operation unit 52 or may be configured to be bridged from both side surfaces.

  Further, the specific shape, dimensions, material, and the like of the lid-type switch guard member 28c are not particularly limited, and can exhibit strength that does not cause damage or irreversible deformation even when pressed from above with a palm or the like, And the shape, dimension, material, etc. which form the space which can push the pressing surface of operation permission switch 21 should just be adopted.

  Further, as shown in the upper side of FIG. 7, in the present embodiment, the switch guard member 28 c is configured to cover almost the entire pressing surface of the operation permission switch 21 indicated by the dotted line in the drawing. It may be a degree that covers less than half or a part that covers a part. In any case, the entire pressing surface of the driving permission switch 21 must not be carelessly pressed from the upper side, and the operating display LED 22a adjacent to the driving permission switch 21 is hidden from view when viewed from the user. For example, the area of the pressing surface covered with the lid-type switch guard member 28c is not particularly limited.

(Embodiment 4)
In the first and second embodiments, the switch guard member 28a or 28b is configured as a flat wall-shaped protrusion, but the present invention is not limited to these configurations. This point will be specifically described with reference to FIGS. FIGS. 8A to 8C are comparison views of a plan view and a side view showing the configuration of the switch guard members 28d to 28f of the present embodiment, respectively.

  In the first to third embodiments, the operation permission switch 21 is configured as a circular membrane switch. In the first and second embodiments, each of the circular operation permission switches 21 has a flat wall. The switch guard members 28a or 28b are arranged adjacent to each other in a positional relationship corresponding to the tangent line of the circumference.

  In contrast, in the present embodiment, in the circular operation permission switch 21, the rear half (FIG. 8A) or the front half (FIG. 8B) of the circumference or the entire circumference (FIG. 8). A curved or cylindrical switch guard member 28d, 28e or 28f is provided so as to cover (c)). The flat wall-shaped switch guard members 28a and 28b are configured to surround a part of the periphery of the operation permission switch 21, but in the present embodiment, they surround at least half of the periphery of the operation permission switch 21. It becomes composition. Therefore, depending on the configuration of the sanitary washing device 50A, the configuration of the toilet room, etc., the function of preventing erroneous operation may be more excellent than the flat switch guard members 28a and 28b.

  Of course, as described in the second embodiment, when the user uses the sanitary washing device 50A, the user can easily place the palm or the like on the operation surface of the fixed operation unit 52 under any circumstances.
