  The present invention relates to a sanitary washing device provided in a toilet and capable of washing a local part of a human body.

In a sanitary washing device that performs washing by spraying washing water onto a human body part, for example, scale or filth may adhere to the nozzle. Therefore, a technique has been proposed in which cleaning water is sprayed onto the surface of a nozzle to remove filth and the like at the start and end of sanitary cleaning (Patent Document 1). In addition, a technique has also been proposed in which cleaning water is sprayed periodically onto the surface of the nozzle to keep the nozzle wet at all times, thereby preventing dirt and the like from adhering to the nozzle surface during sanitary cleaning (Patent Document 2). .
Japanese Patent No. 2878460 JP 2003-293431 A

  In the first conventional technique for cleaning the nozzle at the start and end of sanitary cleaning, the nozzle is cleaned both before the user uses sanitary cleaning and after the user finishes sanitary cleaning. It is possible to suppress dirt and the like from adhering to the nozzle. However, there are cases where it is not possible to remove stool and dirt such as scale adhering to the nozzles only by nozzle cleaning performed before and after sanitary cleaning. When dirt or the like adheres to the nozzle, the user must manually clean the nozzle, which requires time and effort for nozzle cleaning and is low in usability.

  In the second prior art that keeps the nozzle surface wet at all times, since the cleaning water is sprayed on the nozzle periodically, the cleaning water is often sprayed unnecessarily, which may waste the cleaning water and electricity. . That is, in the second prior art, for example, even when the hygienic cleaning device is used at a relatively high frequency such as when working at sunrise or immediately before going to bed, The washing water is sprayed to the nozzle. Therefore, there are many cases where cleaning water is unnecessarily injected, and the maintenance cost of the sanitary cleaning device increases.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a sanitary washing apparatus that can reduce the trouble of nozzle cleaning by improving the performance of washing the nozzle. . Another object of the present invention is to clean the nozzle with normal performance when switching the local cleaning mode with nozzle retraction and re-extension, and to clean the nozzle with improved performance when stopping the local cleaning mode. Accordingly, it is an object of the present invention to provide a sanitary washing device that can keep the nozzle clean and reduce the trouble of cleaning the nozzle.

The invention according to claim 1 is a sanitary washing device for washing a local part of a human body by injecting washing water from an injection hole provided in a nozzle based on an instruction input from a user. A plurality of operations can be selected, and an operation unit that outputs a plurality of signals according to the selected operation, a nozzle cleaning unit that cleans the nozzles, and a nozzle cleaning unit that responds to a signal received from the operation unit Nozzle cleaning control means for controlling the cleaning time of the nozzle, and the nozzle cleaning means sprays cleaning water from the outside of the nozzle while moving the nozzle at a moving speed controlled by the nozzle cleaning control means. The nozzle cleaning control means is capable of cleaning the nozzle by controlling the moving speed of the nozzle in accordance with the signal received from the operation means. Controlling the cleaning time of the nozzle by stages.

  In such a sanitary washing apparatus, when the user instructs local washing through the operation means, washing water is jetted from the nozzle injection hole toward the human body local area, and the local area is washed. The washing water sprayed from the nozzles wash away the stool and the like adhering to the user's body part, and falls to the ball part of the toilet body.

  The operating means may be configured as an operation panel provided integrally with the sanitary washing device, for example, or may be configured as a separate device from the sanitary washing device such as a remote controller. Also good. The local cleaning mode means a control operation for cleaning a local body part, and examples thereof include “butt cleaning” and “bide cleaning”. In addition to these, for example, a local cleaning mode in which the buttocks are cleaned with a soft water flow can be used. The operation means includes an operation switch corresponding to each of the plurality of local cleaning modes, a switch for stopping the local cleaning, and the like. The nozzle cleaning control means controls nozzle cleaning, and controls the nozzle cleaning time based on the signal received from the operation means. Therefore, this sanitary washing device can appropriately control the nozzle washing time in accordance with a signal from the operation means, and can reduce the trouble of the nozzle cleaning work by the user.

When the moving speed of the nozzle is made slower, the time for which the cleaning water is sprayed on the nozzle, that is, the cleaning time for the nozzle becomes longer, and the amount of the cleaning water used for cleaning the nozzle also increases. The longer the nozzle cleaning time, the higher the possibility of removing dirt attached to the nozzle. Here, as the moving speed of the nozzle, as shown in claim 7 , a retreating speed when the nozzle is retreated can be exemplified.

According to a second aspect of the present invention, in the first aspect , the nozzle cleaning control unit sets the first movement speed when receiving the first type signal from the operation unit, and receives the second type signal from the operation unit. In this case, the second moving speed that is slower than the first moving speed is set, and the first type signal is a signal that requests switching of the local cleaning mode between the plurality of local cleaning modes. The second type of signal is a signal for requesting stop of the local cleaning being executed.

  For example, when switching of the local cleaning mode is requested from the operation unit, such as when the user instructs switching from the butt cleaning to the bidet cleaning, the nozzle cleaning control unit selects the first movement speed. Thereby, compared with the case where the second moving speed is selected, the nozzle cleaning time can be shortened, and the local cleaning mode can be quickly switched. On the other hand, when the second type of signal is output from the operation means, for example, when the user wishes to end the buttocks cleaning or the bidet cleaning, the nozzle cleaning control means The second moving speed that is slower is selected. Thereby, the cleaning time of the nozzle can be lengthened, and the possibility of removing dirt and the like from the nozzle can be increased.

  That is, in such a sanitary washing apparatus, only when the local washing is finished, the integrated flow rate of the washing water sprayed to the nozzle can be increased to enhance the nozzle washing ability. As a result, the nozzle can be carefully washed and then housed, and dirt and the like can be prevented from adhering to the nozzle.

In the invention according to claim 3 , in claim 2 , the first type of signal is a signal for switching the local cleaning mode by retracting the nozzle once and then extending again, and the second type of signal is This is a signal for retreating the nozzle to stop the local cleaning. Thus, for example, when the local cleaning mode is switched between the buttocks cleaning and the bidet cleaning, the nozzle is quickly moved at the first moving speed, so that the nozzle is quickly cleaned when the nozzle is retracted and fully extended. be able to. And when butt washing or bidet washing is stopped, the nozzle can be slowly washed when the nozzle is retracted by moving the nozzle slowly at the second movement speed.

According to a fourth aspect of the present invention, in the third aspect , the second type signal includes a signal corresponding to a stop command switch provided in the operation means or a signal corresponding to a drying command switch provided in the operation means. Either or both of these are included.

  The stop command switch is a switch for stopping the currently executed local cleaning. The drying command switch is a switch for stopping the local cleaning currently being performed and then blowing the hot air to the local body to dry it. In any case, the local cleaning that is being performed is stopped, and another local cleaning is not performed after the stop. Therefore, even if the nozzle is moved at the relatively slow second moving speed, the nozzle can be cleaned over a relatively long cleaning time without inconvenience to the user.

In the invention according to claim 5 , in any one of claims 2 to 4 , when the nozzle cleaning control means receives the second type signal, after moving the nozzle to a predetermined position at the first movement speed, Switch to the second movement speed. That is, the nozzle cleaning control means moves the nozzle quickly to a predetermined position at a relatively fast first moving speed, and then moves the nozzle slowly by switching to a relatively slow second moving speed. Here, the predetermined position can be defined as, for example, a position where nozzle cleaning by the nozzle cleaning means starts to function effectively, or a vicinity of a boundary between a position where the nozzle is easily contaminated and a position where the nozzle is not easily contaminated. By quickly moving the nozzle to the easily contaminated position, the amount of cleaning water sprayed to the easily contaminated area of the nozzle can be increased to effectively remove dirt and the like, and the time required for nozzle cleaning can be shortened. be able to.

According to a sixth aspect of the present invention, in any one of the second to fourth aspects, the nozzle cleaning means is provided so as to cover the nozzle, the cleaning chamber is movably inserted therein, and the cleaning water is provided in the cleaning chamber. And a nozzle driving means for moving the nozzle forward and backward, and when the second type of signal is received, the nozzle cleaning control means causes the nozzle to reciprocate in the cleaning chamber. The nozzle is cleaned by spraying cleaning water from the nozzle cleaning flow path.

  In such a sanitary washing apparatus, when the second type of signal is output from the operation means, the washing water can be repeatedly sprayed while the nozzle is reciprocated in the washing chamber. This makes it possible to increase the cumulative flow rate of cleaning water sprayed to the tip of the nozzle, which tends to get dirty, while changing the direction and momentum where the cleaning water collides with the nozzle. Can be removed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, as will be described in detail below, in the sanitary washing device 1 that switches from local cleaning to nozzle cleaning based on a signal input from the operation unit 3, according to the type of signal input from the operation unit 3. Control the nozzle cleaning ability. As a result, after the local cleaning, the nozzle can be made to stand by after being cleaned cleanly, and dirt and the like are prevented from adhering to the nozzle, thereby reducing the cleaning work by the user.

  FIG. 1 is an explanatory view schematically showing an outline of a sanitary washing device 1 according to the present embodiment. The sanitary washing device 1 is attached to the toilet body of a toilet and cleans a user's human body part, as will be apparent from the examples described later.

  As will be described later, the sanitary washing device 1 includes, for example, a nozzle device 2, an operation unit 3, a sanitary washing control unit 4 and a nozzle washing control unit 5.

  The nozzle device 2 includes, for example, a nozzle body 2A, a cleaning water supply unit 2B, a nozzle driving unit 2C, and a cleaning chamber 2D. The nozzle device 2 operates the nozzle body 2A and the like in accordance with a control signal input from the nozzle cleaning control means 5 or the sanitary cleaning control means 4, and performs cleaning of the nozzles and cleaning of the human body part (hygiene cleaning).

  The nozzle body 2A is provided, for example, so as to face the ball part of the toilet body from the rear part of the toilet seat. A plurality of injection holes 2A1 and 2A2 are provided on the tip side of the nozzle body 2A facing the ball portion. Flow channels 2A3 and 2A4 communicating with the respective injection holes 2A1 and 2A2 are formed inside the nozzle body 2A. One flow path 2A3 communicates with one injection hole 2A1, and the other flow path 2A4 communicates with the other injection hole 2A2.

  The cleaning water supply means 2B supplies cleaning water to each of the injection holes 2A1 and 2A2 and a cleaning chamber 2D described later. The cleaning water supply means 2B includes, for example, a function of heating the cleaning water, a function of pressurizing the cleaning water, a function of adjusting the water flow, a function of switching the flow path, etc. Can be configured.

  The cleaning water supplied from the cleaning water supply means 2B to the nozzle body 2A is injected from the injection holes 2A1 and 2A2 through the flow paths 2A3 and 2A4. When the channel 2A3 is selected, the cleaning water is jetted from the jet hole 2A1. When the channel 2A4 is selected, the cleaning water is jetted from the jet hole 2A2. Further, when both the flow paths 2A3 and 2A4 are selected, the cleaning water is jetted from the jet holes 2A1 and 2A2, respectively.

  The nozzle driving means 2C is for expanding and contracting the nozzle body 2A. The nozzle driving means 2C can be constituted by, for example, a driving motor, a pulley, a belt, a latch, etc., as will be apparent from the embodiments described later. For example, other mechanisms such as a linear motor may be used. The nozzle body 2A moves in either the arrow F direction or the R direction by the nozzle driving means 2C. The arrow F direction is a direction toward the ball part of the toilet body, and is also referred to as a front direction. The arrow R direction is a direction toward the toilet seat rear part opposite to the ball part, and is also referred to as a rear direction.

  The cleaning chamber 2D is for cleaning the nozzle body 2A, and constitutes a “nozzle cleaning unit” together with the cleaning water supply unit 2B and the nozzle driving unit 2C. The cleaning chamber 2D is provided so as to be movable relative to the nozzle body 2A, and an opening is formed on the surface of the toilet body facing the ball portion. Further, an insertion portion through which the nozzle body 2A is movably inserted is formed in the front-rear direction (arrow F, R direction) of the cleaning chamber 2D.

  For example, the cleaning chamber 2D is provided on the rear side of the toilet seat so as to cover the outside of the nozzle body 2A. The nozzle body 2A is moved in the front-rear direction through the cleaning chamber 2D by the nozzle driving means 2C. Cleaning water is supplied to the cleaning chamber 2D from the cleaning water supply means 2B, and this cleaning water is sprayed onto the surface of the nozzle body 2A in the cleaning chamber 2D.

  The nozzle body 2A moves, for example, between a retracted position (first position) retracted to the toilet seat rear part and an extended position (second position) extending into the ball part. The extension position can be adjusted according to the user's preference. When the nozzle body 2A is in the contracted position, the injection holes 2A1 and 2A2 are respectively located in the cleaning chamber 2D. When the nozzle body 2A is in the extended position, the injection holes 2A1 and 2A2 are located outside the cleaning chamber 2D.

  The above is the mechanical structure of the sanitary washing device 1. Next, the control system structure of the sanitary washing device 1 will be described. The control system structure includes, for example, an operation unit 3, a sanitary cleaning control unit 4, and a nozzle cleaning control unit 5.

  The operation means 3 is an instruction device for the user to operate the sanitary washing device 1, and is configured as a remote controller, for example. An instruction input by the user from the operation unit 3 is input to the sanitary cleaning control unit 4 and the nozzle cleaning control unit 5 of the sanitary cleaning apparatus 1 as a voltage signal or a command. The operation means 3 and the sanitary washing control means 4 can be connected by wire or wireless.

  The operation means 3 can be provided with a plurality of switches 3A, 3B, 3C, 3D. Each of these switches 3A to 3D is a switch for instructing an operation related to the local cleaning, and can also be called a local cleaning related switch or the like. Each of the switches 3A to 3D is configured as a manual operation switch, for example, but is not limited thereto, and may be configured as a voice input device that recognizes a voice uttered by a user.

  The switch 3A is a buttocks washing switch. When the user operates the switch 3A, the sanitary washing control means 4 executes the buttocks washing. The switch 3B is a bidet cleaning switch. When the user operates the switch 3B, the sanitary washing control means 4 executes bidet washing. The switch 3C is a stop switch. When the user operates the switch 3C, the sanitary washing control unit 4 stops the operation currently being executed. The switch 3D is a drying switch. When the user operates the switch 3D, the sanitary washing control unit 4 stops the local washing currently being performed, and blows hot air to the local to dry it.

  The sanitary washing control means 4 controls the local washing operation and the like. In the local cleaning (ie sanitary cleaning), cleaning is performed by spraying cleaning water onto the human body local area of the user. In the case of butt cleaning, the sanitary cleaning control means 4 extends the nozzle body 2A into the toilet body and jets cleaning water from the butt cleaning injection hole. Similarly, in the case of bidet cleaning, the sanitary cleaning control means 4 extends the nozzle body 2A into the toilet body and jets cleaning water from the bidet cleaning spray hole.

  The sanitary washing control means 4 moves the nozzle body 2A to the extension position set by the user when the user instructs the execution of sanitary washing via the operation means 3, and then the nozzles 2A1, 2A2 The cleaning water is jetted from the jet hole selected by the user. The start and end of sanitary cleaning is notified to the nozzle cleaning control means 5, and a nozzle cleaning process in cooperation with sanitary cleaning is executed as described later.

  The nozzle cleaning control means 5 controls execution and stop of the nozzle cleaning process. The nozzle cleaning process means a series of preset cleaning operations for cleaning the nozzle body 2A. Details of the nozzle cleaning step will be described later.

  The nozzle cleaning control means 5 can move the nozzle body 2A backward at a plurality of speeds of the first backward speed V1 and the second backward speed V2. The first reverse speed V1 corresponds to the “first movement speed”, and the second reverse speed V2 corresponds to the “second movement speed”. The second reverse speed V2 is set to be slower than the first reverse speed V1.

  The method for selecting the plurality of reverse speeds V1 and V2 will be described in more detail in the embodiments described later. Briefly described above, the nozzle cleaning control means 5 selects one of the speeds V1 and V2 based on the type of signal input from the operation means 3. The nozzle cleaning control means 5 cleans the surface of the nozzle body 2A by spraying cleaning water on the nozzle body 2A in the cleaning chamber 2D while retracting the nozzle body 2A at the selected speed.

  As will be described later, the nozzle cleaning control means 5 selects the first reverse speed V1 when switching the local cleaning mode with the backward movement and re-extension of the nozzle body 2A. As a result, the local cleaning mode can be quickly switched. On the other hand, when the local cleaning is stopped, the nozzle cleaning control means 5 selects the second reverse speed V2. As described above, examples of the case where the local cleaning is stopped include a case where the user operates the stop switch 3C or the drying switch 3D. When the local cleaning is stopped, that is, when the user finishes using the local cleaning, the nozzle main body 2A is cleaned in the cleaning chamber 2D while the nozzle main body 2A is moved backward at a slower speed V2. By reducing the retreating speed of the nozzle body 2A to V2, the time for the nozzle body 2A to pass through the cleaning chamber 2D, that is, the cleaning time becomes longer. As a result, the cleaning water sprayed to the nozzle body 2A in the cleaning chamber 2D The integrated flow rate increases. Accordingly, it is possible to spray a large amount of washing water on the nozzle body 2A to remove dirt and the like, and it is possible to wait in a state where the nozzle body 2A is cleaned more than usual.

  Next, the nozzle cleaning process will be described. The nozzle cleaning process can be roughly divided into, for example, a body cleaning process and an injection hole cleaning process. The body cleaning step is a step of cleaning the body of the nozzle body 2A while moving the nozzle body 2A forward or backward. In the body cleaning process, cleaning water is sprayed from the cleaning chamber 2D toward the surface of the nozzle body 2A. Accordingly, the cleaning water is sprayed from the outer side of the outer peripheral surface of the nozzle body 2A to the peripheral surface passing through the cleaning chamber 2D, and the dirt and the like adhering to the peripheral surface is removed. The cleaning water from which dirt and the like have been removed from the nozzle body 2A falls into the ball portion from the lower opening of the cleaning chamber 2D.

  The injection hole cleaning step is a step of cleaning each injection hole 2A1, 2A2 of the nozzle body 2A and the vicinity thereof. In the injection hole cleaning step, the nozzle body 2A is positioned at the retracted position, the injection holes 2A1, 2A2 are accommodated in the cleaning chamber 2D, and the cleaning water is injected from the injection holes 2A1, 2A2, respectively. This washing water removes each of the injection holes 2A1, 2A2 and the filth attached to the vicinity thereof. Since each injection hole 2A1, 2A2 is located in the cleaning chamber 2D, each injection hole 2A1, 2A2 does not fly outside the toilet body. The cleaning water sprayed from each of the injection holes 2A1 and 2A2 collides with the inner wall of the cleaning chamber 2D and rebounds, and collides with the peripheral surface of the nozzle body 2A located in the cleaning chamber 2D from various directions. Thereby, not only each injection hole 2A1, 2A2 and its vicinity but the front end side peripheral surface of the nozzle body 2A is also cleaned.

  In the nozzle cleaning process, the body cleaning process and the injection hole cleaning process are each performed at least once. Although details will be described later, when sanitary cleaning is performed, the injection hole cleaning process (pre-cleaning) → trunk cleaning process (stretching cleaning) → sanitary cleaning (local cleaning) → trunk cleaning process (backward cleaning) → jetting The nozzle body 2A is cleaned in the order of the hole cleaning step (post-cleaning). In the backward cleaning in which the body cleaning process is performed while the nozzle body 2A is retracted, one of the backward speeds V1 and V2 is used according to the signal from the operation means 3 as described above.

  As described above, the sanitary washing device 1 of the present embodiment sets the retreating speed of the nozzle body 2A to either V1 or V2 according to the signal from the operation means 3, and cleans the nozzle body 2A in the washing chamber 2D. To do. As a result, the nozzle cleaning ability at the end of the local cleaning can be enhanced without impairing the convenience for the user, and the user's manual cleaning work can be reduced and the usability can be improved. Hereinafter, this embodiment will be described in detail.

The nozzle mechanism includes, for example, a nozzle body 101 in which a plurality of injection holes 102A and 102B are formed, a cleaning chamber 103, a nozzle motor 120, a driving pulley 121, driven pulleys 122 and 122, a timing belt 123, and a tensioner. 124, a latch part 125, and a flow path switching valve 126.

  The nozzle main body 101 corresponds to the nozzle main body 2A in FIG. 1 and is provided to be extendable so as to face the ball portion of the toilet main body 11 as described together with FIG. Further, the nozzle body 101 is formed with flow paths communicating with the respective injection holes 102A and 102B, and the cleaning water from the pulsating device unit 115 is supplied to these flow paths.

  The cleaning chamber 103 corresponds to the cleaning chamber 2D in FIG. 1, and is provided at the front portion of the casing 14 so as to cover the outside of the nozzle body 101 as described above. The cleaning chamber 103 includes an insertion portion through which the nozzle body 101 is movably inserted, and an opening for dropping the cleaning water sprayed into the cleaning chamber 103 onto the ball portion. Therefore, the cross section of the cleaning chamber 103 in the direction orthogonal to the nozzle body 101 has a downward substantially U-shape or C-shape. The cleaning chamber 103 is connected to the flow adjustment unit 114 via the flow path 104. The cleaning water supplied from the flow adjustment unit 114 via the flow path 104 is jetted into the cleaning chamber 103.

  A latch portion 125 is provided in the middle of the nozzle body 101 at the rear side of the cleaning chamber 103. The nozzle body 101 is fixed to the timing belt 123 by a latch portion 125. The timing belt 123 is wound around the drive pulley 121 and the driven pulleys 122 and 122, and moves in either the clockwise direction or the counterclockwise direction by the rotational force of the nozzle motor 120. As the timing belt 123 moves clockwise, the nozzle body 101 moves backward. As the timing belt 123 moves counterclockwise, the nozzle body 101 moves forward. The tension of the timing belt 123 is adjusted to an appropriate value by the tensioner 124.

  The flow path switching valve 126 is a valve for selecting one or both of the injection holes 102A and 102A and supplying cleaning water. The flow path switching valve 126 is located between the nozzle body 101 and the pulsating device unit 115 and is provided at the rear portion of the nozzle body 101.

  As described in conjunction with FIG. 1, the nozzle main body 101 is, for example, a retracted position (first position) where the front end side of the nozzle main body 101 is retracted at the rear portion of the toilet seat 12 and a front end side of the nozzle main body 101 is extended into the ball portion. It moves between at least two points with the extension position (second position). The extension position can be adjusted by operating the remote controller 20. When the nozzle body 101 is in the retracted position, the injection holes 102A and 102B are located in the cleaning chamber 103, respectively. When the nozzle body 101 is in the extended position, the injection holes 102 </ b> A and 102 </ b> B are located outside the cleaning chamber 103.

  FIG. 7 is a perspective view when the nozzle body 101 is in the retracted position. In FIG. 7, the tip side of the nozzle body 101 is shown enlarged. As shown in FIG. 7, when the nozzle main body 101 is retracted to the retracted position, the injection holes 102 </ b> A and 102 </ b> B are respectively located in the cleaning chamber 103. Accordingly, when the cleaning water is sprayed from the respective injection holes 102A and 102B, the cleaning water collides with the inner wall of the cleaning chamber 103 and rebounds, and collides with the peripheral surface of the nozzle body 101 from various directions. The cleaning water from which the dirt on the tip side of the nozzle body 101 has been removed falls from the lower surface side of the cleaning chamber 103 into the ball portion.

  FIG. 8 is a perspective view showing how the nozzle body 101 moves between the contracted position and the extended position. The nozzle body 101 moves in the front-rear direction through the cleaning chamber 103. Therefore, while the nozzle main body 101 is moving, the body of the nozzle main body 101 can be cleaned by spraying cleaning water from the nozzle cleaning channel 104. In this embodiment, the nozzle cleaning capability is controlled by switching the retreating speed when the nozzle body 101 retreats to the retracted position to either V1 or V2 (V2 <V1).

  FIG. 9 is a flowchart showing a normal nozzle cleaning process. In the normal nozzle cleaning process, as described below, the nozzle body 101 is cleaned in cooperation with sanitary cleaning. Based on the signal from the seating sensor 30, the control unit 300 determines whether or not the user has been seated on the toilet seat 12 (S10).

  When it is determined that the user is seated on the toilet seat 12 (S10: YES), the control unit 300 keeps the nozzle body 101 in the retracted position for a few seconds to 10 seconds from the injection holes 102A and 102B. While spraying each for about several seconds, warm water is prepared by the heat exchange unit 113, and the prepared warm water is kept warm (S11).

  When the start of sanitary cleaning is instructed from the remote controller 20 (S12: YES), the control unit 300 first causes the nozzle hole cleaning process to be executed in the nozzle cleaning process before starting the sanitary cleaning (S13). ). In the spray hole cleaning step, the cleaning water is sprayed from each of the spray holes 102A and 102B in a state where the nozzle body 101 is retracted to the retracted position and the spray holes 102A and 102B are accommodated in the cleaning chamber 103.

  After the injection hole cleaning process is completed, the control unit 300 rotates the nozzle motor 120 in the forward direction to extend the nozzle body 101 to the extended position. The extension position can be adjusted by the user. The nozzle body 101 extends from the retracted position to the extended position through the cleaning chamber 103.

  The controller 300 causes the body cleaning process constituting a part of the nozzle cleaning process to be executed while the nozzle body 101 is extended (S14). That is, the control unit 300 switches the flow path in the flow adjustment unit 114 and supplies the cleaning water to the nozzle cleaning flow path 104. Thereby, the trunk | drum of the nozzle main body 101 extended toward the inside of a ball | bowl part can be wash | cleaned in the washing | cleaning chamber 103. FIG. The range to be cleaned by the body cleaning process is from the tip side of the nozzle body 101 to a portion located in the cleaning chamber 103 when the nozzle body 101 reaches a predetermined extension position. The body portion cleaning process shown in S14 is executed when the nozzle body 101 is advanced from the retracted position to the extended position, and can be called, for example, an extension time cleaning process.

  When the front end side of the nozzle body 101 reaches a predetermined extension position, the control unit 300 performs sanitary washing by injecting cleaning water from the injection holes selected by the user among the injection holes 102A and 102B ( S15).

  The user can perform sanitary cleaning only for a preset time, and can also perform sanitary cleaning until the stop button 23A of the remote controller 20 is operated. Further, as will be described later, the user can select a local cleaning mode different from the first selected local cleaning mode by operating the remote controller 20. Until the sanitary cleaning is completed, the cleaning water is sprayed from the selected spray hole toward the local body part (S15, S16).

  When sanitary cleaning is completed automatically or manually (S16: YES), the control unit 300 executes the trunk cleaning process again (S17). That is, the controller 300 supplies cleaning water to the nozzle cleaning flow path 104 while rotating the nozzle motor 120 in the reverse direction. As a result, the body surface of the nozzle body 101 is cleaned in the cleaning chamber 103 while retracting from the extended position to the retracted position. The trunk cleaning process shown in S17 is performed when the nozzle body 101 is retracted from the extended position to the retracted position, and can be called, for example, a reverse cleaning process. Then, when the nozzle body 101 is retracted to the retracted position, the control unit 300 executes the injection hole cleaning process again (S18).

  Thus, in the normal nozzle cleaning process, the nozzle body 101 is cleaned before and after the start of sanitary cleaning. As a result, the nozzle body 101 can be cleaned automatically before being sanitized, and the nozzle body 101 can be automatically cleaned and then put on standby.

  However, even if the nozzle body 101 is cleaned after sanitary cleaning, not all filth and the like attached to the nozzle body 101 can be completely removed, and a slight amount of filth and the like may remain attached to the nozzle body 101. is there. The dirt attached to the nozzle main body 101 may adhere to the nozzle main body 101 over time, and the nozzle main body 101 may remain dirty. In order to prevent such a situation, for example, it is conceivable to periodically spray cleaning water onto the nozzle body 101. However, in this case, since the cleaning water is mechanically ejected periodically regardless of whether or not the toilet 10 is used (with or without sanitary cleaning), the cleaning water is wasted.

  Therefore, in the present invention, as described below, when the nozzle body 101 is retracted after sanitary cleaning, the cleaning time of the nozzle body 101 is lengthened by reducing the retracting speed of the nozzle body 101 to V2. As a result, the integrated flow rate of the cleaning water sprayed to the nozzle body 101 is increased, the cleaning ability in the backward cleaning process is increased, and dirt attached to the nozzle body 101 is removed.

  FIG. 10 is a flowchart showing a process when the local cleaning mode is switched. The controller 300 determines whether sanitary cleaning (local cleaning) is being performed (S20). When sanitary washing is being performed (S20: YES), the controller 300 determines whether or not the switch of the remote controller 20 has been operated (S21).

  Here, in S21, it is determined which of the switches 23A to 23E shown in FIG. 4 has been operated. That is, whether or not the switches 23A to 23E accompanied by the movement of the nozzle body 101 are switched when the local cleaning mode is switched is detected. Other switches, for example, the switches 24A to 24D, for example, can switch modes without advancing and retreating of the nozzle body 101, and therefore need not be determined in S21.

  When any one of the predetermined switches 23A to 23E accompanied by the advance / retreat operation of the nozzle body 101 is operated (S21: YES), the control unit 300 controls the cleaning time according to the type of the switch operated by the user. To do.

  When the signal input from the remote controller 20 is a signal corresponding to the stop switch 23A, the control unit 300 selects the second backward speed V2 for the nozzle body 101 and slowly moves the nozzle body 101 at the speed V2 (S30). . The controller 300 causes the body cleaning process (reverse cleaning process) to be performed while the nozzle body 101 is retracted at the speed V2 (S31). When the nozzle body 101 is retracted to the retracted position, an injection hole cleaning process (post-cleaning) is performed (S32), and this process is completed.

  When the stop switch 23A is operated, it means the end of the local cleaning, and does not switch to another local cleaning mode. Therefore, no inconvenience occurs even if it takes more time than usual to clean the nozzle body 101. Therefore, the control unit 300 cleans the nozzle body 101 while removing the attached dirt and the like while moving the nozzle body 101 backward at a relatively slow speed V2.

  On the other hand, when the user operates any one of the switches 23B to 23D other than the stop switch 23A or the drying switch 23E, the control unit 300 selects the first reverse speed V1 (V1> V2), and the nozzle The main body 101 is retracted faster than in the case of V2 (S40). The controller 300 performs the body cleaning process while retracting the nozzle body 101 at the speed V1 (S41), and executes the injection hole cleaning process when the nozzle body 101 reaches the retracted position (S42). After cleaning the nozzle body 101 in this way, the control unit 300 moves the nozzle body 101 again from the retracted position to the extended position (S43), and executes the local cleaning selected by the user in S21 (S44). .

  For example, when the user switches to bidet cleaning in the middle of buttocks cleaning, or vice versa, or when the user switches from buttocks cleaning to “soft cleaning”, the nozzle body 101 is once cleaned and initialized. After returning to the state, a new cleaning mode (local cleaning mode) is executed again. Therefore, unlike the case where only the local cleaning mode is stopped, it is necessary to stop the currently executing local cleaning mode, clean the nozzle body 101, and then shift to another local cleaning mode. For this reason, when performing the local cleaning mode accompanied by the forward / backward movement of the nozzle body 101, that is, when shifting the local cleaning mode via the initial state of the nozzle body 101, the control unit 300 causes the nozzle body 101 to be relatively fast. The retreat is performed at the speed V1, and the normal retreat cleaning is performed.

  When the user operates the drying switch 23E, the controller 300 selects the second retraction speed V2 (S50), and executes the trunk cleaning process while slowly retreating the nozzle body 101 (S51). When the nozzle body 101 reaches the retracted position, the control unit 300 executes the injection hole cleaning process (S52). And the control part 300 supplies the warm air produced | generated by the warm air production | generation apparatus toward a human body local part (S53). The hot air generating device includes, for example, a heating device such as a heater and a blowing device such as a fan. Although FIG. 10 shows the case where the warm air is output after the cleaning of the nozzle body 101 is completed, the present invention is not limited to this, and the warm air may be output during the cleaning of the nozzle body 101.

  When the user operates the drying switch 23E, it means that the use of the currently performed local cleaning is finished, and therefore the control unit 300 stops the local cleaning and outputs hot air. Therefore, as in the case where the stop switch 23A is operated, the operation of the drying switch 23E means the end of the local cleaning currently in use, and there is no inconvenience to the user even if the cleaning time is increased. Therefore, as described above, the control unit 300 executes the body cleaning process of the nozzle body 101 at a relatively slow speed V2, and removes dirt and the like attached to the nozzle body 101.

  Thus, in this embodiment, since the cleaning time of the nozzle body 101 is changed according to the operation of the remote controller 20 by the user, the nozzle cleaning capability can be changed according to the usage pattern of the sanitary cleaning device.

  In particular, when the local cleaning is finished, the body cleaning process is executed while the nozzle body 101 is moved backward at a relatively slow speed V2, so that the time for spraying the cleaning water to the nozzle body 101 can be increased. Thus, the nozzle body 101 can be sufficiently cleaned.

  A second embodiment of the present invention will be described with reference to FIG. In this embodiment, when either the stop switch 23A or the drying switch 23E is operated, the body is cleaned while the nozzle body 101 is quickly retracted to a predetermined position, and then the nozzle body 101 is slowly retracted. Wash while.

  FIG. 11 is a flowchart showing the mode switching process according to this embodiment. Since this flowchart includes steps common to the flowchart shown in FIG. 10, redundant description will be omitted, and the description will focus on the features that are characteristic of the present embodiment. The steps added in the present embodiment are indicated by bold lines.

  When the user operates the stop switch 23A via the remote controller 20 (S22: stop switch), the control unit 300 selects the first retraction speed V1 and quickly retreats the nozzle body 101 while cleaning the body. The process is executed (S33). The control unit 300 determines whether or not the nozzle main body 101 has been retracted to a predetermined position (S34), and until the nozzle main body 101 reaches a predetermined position (S34: NO), the nozzle main body 101 at the first reverse speed V1. The cleaning water is sprayed in the cleaning chamber 103 while quickly retreating.

  Here, the predetermined position can be set as a position where about 1/3 of the total length of the nozzle body 101 is retracted. That is, since the range of about 1/3 from the base end side of the nozzle body 101 is less contaminated than the front side of the nozzle body 101, the range of about 1/3 from the base end side is a normal barrel cleaning at the speed V1. To implement.

  When the total length of the nozzle body 101 is expressed as a percentage with the base end side of the nozzle body 101 as the start point and the tip end side as the end point, for example, a range of about 0% (base end side) to 30% is the cylinder at the speed V1. A partial cleaning process is performed. For example, in the range of 30% to 100% (front end side), the trunk cleaning process is performed at a slower speed V2. Since the speed V1 is higher than the speed V2, the body cleaning at the speed V1 can be rephrased as high-speed body cleaning, and the body cleaning at the speed V2 can be restated as low-speed body cleaning.

  In addition, the said numerical range is an example, Comprising: This invention is not restricted to this, For example, the range of 0%-50% carries out high-speed trunk washing (V1), and the range of 50%-100% carries out low-speed trunk washing. (V2) may be configured. The cleaning time of the nozzle body 101 is shortened as the range for performing high-speed body cleaning increases. Moreover, it is good also as a structure which controls the range (or range which performs low-speed trunk | drum cleaning) which performs high-speed trunk | drum washing | cleaning based on the utilization condition etc. by a user. For example, when the bidet cleaning is stopped, it is possible to determine that the nozzle body 101 is relatively less soiled and to widen the range of high-speed body cleaning.

  Similarly to the above, when the user operates the drying switch 23E (S22: drying switch), the control unit 300 performs the trunk cleaning process while quickly retreating the nozzle body 101 at the speed V1 until the predetermined position is reached. Execute (S54, S55).

  Configuring this embodiment like this also achieves the same effects as the first embodiment. In addition, in this embodiment, the high-speed body cleaning process is applied to a predetermined range on the base end side that is relatively difficult to get dirty, and the low-speed body cleaning process is applied to the distal end side that is relatively easily dirty. Therefore, it can wash | clean efficiently using many washing | cleaning water in the range which is easy to become comparatively dirty.

  A third embodiment of the present invention will be described with reference to FIG. In this embodiment, the tip side of the nozzle body 101 is carefully cleaned by spraying cleaning water on the tip side of the nozzle body 101 while reciprocating the tip side of the nozzle body 101 in the cleaning chamber 103.

  FIG. 12 is a flowchart showing the mode switching process according to this embodiment. Since this flowchart includes steps common to the flowchart described with reference to FIG. 11, overlapping description will be omitted, and description will be focused on the characteristic part of the present embodiment.

  Also in this embodiment, when the user operates either the stop switch 23A or the drying switch 23E during the local cleaning, the control unit 300 performs the high-speed body cleaning until the nozzle body 101 reaches a predetermined value. (S33, S34, S54, S55) After that, low-speed body cleaning is performed (S30, S31, S50, S51).

  When the nozzle body 101 is retracted to the retracted position, the control unit 300 performs an injection hole cleaning process (S32, S52). Further, the control unit 300 sprays cleaning water toward the nozzle body 101 while moving the front end side of the nozzle body 101 back and forth slightly in the cleaning chamber 103 and / or spray holes 102A and 102B. The cleaning water is discharged from (S35, S56).

  For example, the control unit 300 performs cleaning while repeatedly moving the tip side of the nozzle body 101 back and forth within the cleaning chamber 103 within a range in which the tip side of the nozzle body 101 does not protrude outside the cleaning chamber 103. Due to this reciprocating movement, the cleaning water collides with the tip of the nozzle body 101 from various directions and the cleaning water pressure in the cleaning chamber 103 also fluctuates more than in the case of low-speed body cleaning. The filth is removed.

  The range in which the tip side of the nozzle body 101 is reciprocated in the cleaning chamber 103, the frequency of reciprocation, the number of reciprocations, and the like can be appropriately controlled based on, for example, the usage state of the user.

  The nozzle cleaning operation in S35 and S56 described above can be called, for example, a reciprocating cleaning process in the cleaning chamber. In addition, although the case where S32 and S35 and S52 and S56 were each comprised by the separate step was illustrated, this invention is not restricted to this, An injection hole washing | cleaning process and a washing chamber reciprocating washing process can also be integrated. In this case, S32 and S52 are removed from the flowchart shown in FIG.

  The present invention is not limited to the above-described embodiment. A person skilled in the art can make various additions and changes within the scope of the present invention. For example, in the third embodiment, the case of applying to the second embodiment has been described. However, the third embodiment can also be applied to the first embodiment.
