Description

  The present invention relates to a nozzle device that ejects cleaning water for cleaning a local part of a human body.

  An example of a sanitary washing device is shown in FIG. When the user sits on the toilet seat 114 and cleaning is started by the operation unit 111, the cleaning nozzle 115 in the sanitary cleaning apparatus moves forward, and cleaning water is ejected from the outlet 116 of the cleaning nozzle 115. When the user operates the operation unit 111 when stopping, the cleaning water stops and the cleaning nozzle 115 is stored in the main body 113.

  Conventionally, the nozzle device of this type of sanitary washing device has a synchronous motor, a pulse motor, a servo motor, etc. as a drive device for moving the washing nozzle 115 forward and backward, and a motor 222 that rotates in synchronization with its power frequency and pulse. Means for counting the number of cycles of the power supply frequency of the motor 222; means for determining the current value of the cleaning nozzle 115 based on the counted number of cycles; and means for comparing the current value with a preset value stored in advance. The power supply circuit of the motor 222 is ON / OFF controlled by a comparison value between the current value and the specified value. As a result, there is one that positions the cleaning nozzle 115 at the storage position and the two positions in use (see, for example, Patent Document 1).

  50, when the cleaning is started by the operation unit 111 (FIG. 49), the motor 222 is rotated in the forward direction by the control unit 224, and the gear is driven by the worm gear 221 of the motor 222. 220 rotates and the rotation is transmitted to the rack 219 below the nozzle, and the cleaning nozzle 115 advances. At this time, the sensor unit 223 also rotates simultaneously with the rotation of the motor 222, and the control unit 224 moves to the target position by the output of the sensor unit 223. The reverse direction is similarly controlled.

51A and 51B are configuration diagrams of the motor 222 and the sensor unit. When the motor 222 is rotated, the position of the cleaning nozzle 115 is adjusted by the transmission type photo interrupter 326 installed in the motor 222 and the rotating body 327 with a slit that transmits or blocks the light of the photo interrupter 326. It was detected by the number of rotations.
Japanese Patent Laid-Open No. 61-229039

  However, in the above-described conventional configuration, when the cleaning nozzle 115 is moved forward and backward, a fluctuation in driving resistance due to a kink or the like, or a load on the motor 222 increases due to an external force, and the motor 222 is temporarily or partially predetermined. When a deviation due to so-called motor slip that impairs the rated rotation occurs, the position of the cleaning nozzle 115 is shifted from the designated position, and the motor 222 rotates in synchronization with the power frequency or pulse, and the power frequency of the motor 222 In the conventional configuration in which the current value is compared with the preset value stored in advance by determining the current value of the cleaning nozzle 115 based on the means for measuring the number of cycles and the current value of the cleaning nozzle 115 based on the counted number of cycles, a deviation has occurred. Cannot be recognized. In particular, in the case of so-called “move cleaning”, when the forward and reverse rotations of the motor 222 are continuously performed and the cleaning nozzle 115 is continuously reciprocated by a predetermined distance to perform butt cleaning and bidet cleaning, when the misalignment occurs, there is a large deviation due to the accumulation. There was a problem of causing a problem of cleaning the position.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object of the present invention is to provide a nozzle device that can detect and correct the occurrence of a deviation when the nozzle position is displaced.

The rotation of the drive motor 42 is transmitted to the pinion gear 44 at a reduced rotational speed via the worm gear and the transmission gear 43, and the pinion gear 44 rotates so that the nozzle cover 23 having the rack 26a can slide. ing. The drive motor 42 is connected to control means (not shown), and operation is controlled by the control means. A rotation detection sensor 45 that detects the number of rotations of the drive motor 42 is installed at the rear of the drive motor 42.

  31 and 32 are enlarged views of the vicinity of the connecting means during bidet cleaning and buttocks cleaning, respectively. The nozzle cover 23 is provided with connecting means 24 for pulling and moving the nozzle body 22 by moving the nozzle cover 23. The connection means 24 includes a connection receiving portion 46 installed on the side surface of the nozzle body 22 and a connection piece 47 installed on the rear end portion of the nozzle cover 23.

As shown in FIGS. 31 and 32, the connection receiving portion 46 formed of a resin material is installed in parallel with the nozzle body 22 on one side surface of the rear end of the nozzle body 22. The connection receiving portion 46 is provided with a front concave portion 46a and a rear concave portion 46b at two positions with a space in the front and rear directions so as to have the same cross-sectional shape in the circumferential direction. The front concave portion 46a and the rear concave portion 46b The interval is substantially the same as the interval between the bidet cleaning jet 27 and the buttocks cleaning jet 28 of the nozzle body 22.

  The connecting piece 47 is provided on the side surface of the rear end portion of the nozzle cover 23 so as to face the connecting receiving portion 46. The connecting piece 47 is formed of a metal material having elasticity, is held by the connecting piece holding portion 48, and is supported at both ends, and has a structure in which a connecting protrusion 47a is formed at a substantially central portion. 47a has a shape that fits into the front recess 46a and the rear recess 46b of the connection receiving portion 46. When the connecting projection 47a is fitted into the front recessed part 46a or the rear recessed part 46b, the connecting piece 47 and the connection receiving part 46 are connected, and the nozzle body 22 and the nozzle cover 23 can be interlocked.

  The cross-sectional shape of the front and rear recessed portions 46a and 46b is V-shaped, and the connecting projection 47a is V-shaped with a smaller angle than the cross-sectional shape of the front and rear recessed portions 46a and 46b. By adjusting the spring constant so that a load is applied in the direction of the nozzle body 22 even at the time of connection, the vertex of the V-shaped cross section of the front and rear recessed portions 46a and 46b and the vertex of the V-shaped of the coupling protrusion 47a are substantially matched. Deviation caused by the connecting means 24 between the nozzle body 22 and the nozzle cover 23 is minimized.

  Further, the nozzle body 22 is provided with a positioning projection 49, and the positioning projection 49 abuts the front stopper 50 provided at the front portion of the nozzle guide 19 of the casing 16, thereby reducing the sliding range in the forward direction of the nozzle. The rear end of the nozzle body 22 is brought into contact with the nozzle 51 to restrict the sliding range of the nozzle body 22 in the backward direction.

  About the nozzle device comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, in the stowed state where the nozzle shown in FIGS. 13, 19, and 25 is not used, the nozzle cover 23 is located at the rearmost part of the nozzle guide 19, and the nozzle body 22 is also located at the rearmost part of the sliding range. The rear end of the nozzle body 22 is in contact with a rear stopper 51 provided at the rear portion of the nozzle guide 19, and both the nozzle body 22 and the nozzle cover 23 are disposed at the most retracted position. This position is referred to as a storage position. This state is referred to as a stored state. At this time, the connection protrusion 47a of the connection piece 47 is in a state of being fitted into the rear recess 46b of the connection receiving portion 46 as shown in FIG.

  When cleaning is started from the housed state, first, the user operates the operation unit, the control unit starts control, and the rotation of the drive motor 42 is transmitted to the pinion gear 44. The nozzle cover 23 having the meshed rack 26a is moved rearward, but the nozzle cover 23 cannot move rearward any more, so the position in the front-rear direction does not change. With this position as the origin, the subsequent position of the nozzle cover 23 can be controlled while the amount of movement of the nozzle cover 23 is estimated by detecting the rotational speed of the drive motor 42 with the rotational speed detection sensor 45. .

  Next, the drive motor 42 is reversely rotated to move the nozzle cover 23 forward. At this time, the nozzle main body 22 moves forward in a state of being pulled and integrated with the nozzle cover 23 by maintaining the state in which the connection protrusion 47a of the connection piece 47 is fitted in the rear recess 46b of the connection receiving portion 46.

When the user's operation is a bidet cleaning operation, as shown in FIGS. 14, 20, and 26, the nozzle body 22 and the nozzle cover 23 moved forward are in accordance with a preset control sequence. When the rotation speed of the drive motor 42 from the origin state reaches a set value, the drive motor 42 stops. At this time, the positioning protrusion 49 provided on the nozzle main body 22 is in a state of stopping just before contacting the front stopper 50 provided on the front portion of the nozzle guide 19, and this position becomes the standard position for bidet cleaning.

  In this state, the control means controls the washing water supply means, and the bidet washing is started by passing water through the bidet washing flow path 34. The washing water ejected from the bidet washing outlet 27 is ejected through the ejection opening 29. The flow rate is adjusted by the washing water supply means, and the water flow path is switched by the flow path switching valve 37. Since the washing water immediately after passing through the ejector 35 has a high flow velocity, the vicinity of the ejector 35 has a negative pressure, and the washing water is entrained with fine air from the air mixing hole 36, thereby providing a softer feeling of washing.

  At this time, the buttocks cleaning jet outlet 28 is covered with the nozzle cover body 25, and since the sewage generated by the bidet cleaning is not directly applied, it is kept clean.

  Further, when the sealing property of the flow path switching valve 37 is insufficient, the flow rate switching between the buttocks direct-injection cleaning flow path 32, the buttocks swirl cleaning flow path 33, and the bidet cleaning flow path 34 is not performed completely, and the bidet is not performed. A minute amount of water is ejected from the buttocks washing spout 28 even during cleaning, but since the upper part of the buttocks washing spout 28 is covered with the nozzle cover body 25, the water is directed toward the user. There is no fear of being ejected.

  When the drive motor 42 is driven so as to alternately repeat forward rotation and reverse rotation while performing bidet cleaning, the nozzle body 22 and the nozzle cover 23 are swung back and forth with respect to the standard position, and the cleaning water A wider area of the human body can be cleaned.

  When the bidet cleaning is stopped, the drive motor 42 rotates in the reverse direction, and the nozzle body 22 and the nozzle cover 23 move rearward and return to the original storage position. In this configuration, an air mixing hole 36 is formed in the vicinity of the ejector 35 to allow air mixing, but this hole may not be provided. In that case, air is not mixed, but the pulsation feeling of the washing water supply means can be reduced by partially reducing the cross-sectional area of the flow path, and comfortable washing without overloading the delicate bidet is possible. realizable.

  Next, when the butt cleaning is selected, after confirming the origin position of the nozzle cover 23 as in the bidet cleaning, the drive motor 42 rotates to move forward, and the nozzle body 22 and the nozzle cover 23 move forward. This is the same as that for bidet cleaning, but in the case of butt cleaning, the nozzle cover 23 is moved further forward beyond the bidet cleaning position.

  At this time, as shown in FIGS. 15, 21, and 27, the positioning projection 49 provided on the nozzle body 22 contacts the front stopper 50 provided on the front portion of the nozzle guide 19, and the nozzle body 22 moves further forward. To regulate. When the nozzle cover 23 is further moved forward, the connecting projection 47a of the connecting piece 47 is detached from the rear recessed portion 46b. In order to enable such an operation, it is a condition that the drive torque of the drive motor 42 that moves the nozzle in the front-rear direction is larger than the load value required to remove the connection protrusion 47a.

The nozzle main body 22 and the nozzle cover 23 are separated from each other because the connecting protrusion 47a is disengaged from the rear recessed portion 46b, and only the nozzle cover 23 is in front of the nozzle main body 22 whose movement is restricted by the front stopper 50. The connecting protrusion 47a gets stuck in the front recessed portion 46a. When the connecting projection 47a is completely inserted into the front recessed portion 46a, the ejection opening 29 faces the buttocks cleaning ejection port 28 as shown in FIGS. At this point, the upper cover 17 is provided with a nozzle cover front stopper 52 that contacts the nozzle cover 23 without contacting the nozzle body 22 so that the forward movement of the nozzle cover 23 is completed. The position control based on the number of rotations of the drive motor 42 may be performed in advance by a control sequence without providing the nozzle cover front stopper 52.

  The drive motor 42 is moved backward to the standard position for washing the butt by rotating the drive motor 42 slightly in the reverse direction with the coupling protrusion 47a fitted in the front recess 46a in this way. 42 is stopped. This state is the standard position for butt washing shown in FIG.

  When the nozzle cover 23 arrives at the standard position for the buttocks cleaning, the control means controls the washing water supply means and starts water flow into the buttocks direct-injection washing flow path 32 or the buttocks swirl washing flow path 33. The ass cleaning is started. The washing water ejected from the buttocks washing ejection port 28 passes through and is ejected without directly contacting the ejection opening 29. The flow rate is adjusted by the washing water supply means, and the water flow path is switched by the flow path switching valve 37. The ratio of the flow rates flowing to the buttocks direct-injection cleaning channel 32 and the buttocks swirl cleaning channel 33 can be adjusted by the opening degree of the channel switching valve 37.

  When the cleaning water is supplied only to the buttocks direct-injection cleaning flow path 32 by switching the flow path switching valve 37 by the control unit, a concentrated cleaning water flow substantially equal to the diameter of the buttocks cleaning jet outlet 28 is ejected. It can be washed with strong washing water at a pinpoint. On the other hand, when the cleaning water is supplied only to the buttocks swirl cleaning flow path 33, a swirl component around the axis is imparted to the cleaning water, and thus the cleaning water flow diffused from the buttocks cleaning spout 28 is ejected. Can be washed with soft wash water. Further, when cleaning water is supplied to the buttocks direct-injection cleaning flow path 32 and the buttocks swirl cleaning flow path 33 at a predetermined flow rate ratio, the shape of the buttocks cleaning water flow is shaped according to the flow rate ratio from the concentrated state to the diffusion state. Can be controlled.

  Further, when water is passed through the buttocks direct-injection washing flow path 32, the compressed air can be mixed into the washing water by driving the air pump. When washing water mixed with air is ejected from the butt washing outlet 28, the air expands, so that the washing water is given kinetic energy and gathers into a lump to land on the anus. Give rise to Also, by changing the frequency of the pressure fluctuation of the washing water by the washing water supply means and the frequency of the diaphragm of the air pump, the mixing timing of the air becomes irregular, and the washing water that reaches the anus is irregular and intermittent It becomes a cleaning that feels volume compared to intermittent cleaning.

  At this time, the upper part of the bidet washing outlet 27 is covered with the nozzle cover body 25, and the sewage generated by the butt washing does not directly reach the bidet washing outlet 27, so the bidet washing outlet 27 is clean. Kept.

  If the sealing performance of the flow rate switching valve 37 is insufficient, the flow rate of the buttocks direct-injection cleaning channel 32, buttocks swirl cleaning channel 33, and bidet cleaning channel 34 is not completely switched and the buttocks are cleaned. A very small amount of water is also ejected from the bidet washing outlet 27, but the upper part of the bidet washing outlet 27 is covered with the nozzle cover body 25, so that the water may be ejected outside the nozzle. There is no.

  When the drive motor 42 is driven to rotate forward and reverse alternately while the buttocks are being washed, the nozzle body 22 and the nozzle cover 23 are swung back and forth with respect to the standard position, and the washing water Can clean a wider area of the human body.

When stopping the buttocks cleaning, the drive motor 42 rotates in the reverse direction, and the nozzle body 22 and the nozzle cover 23 start moving backward. In the middle of moving backward for storage, the rear end of the nozzle body 22 abuts on a rear stopper 51 provided at the rear portion of the nozzle guide 19, and the nozzle body 22 is restricted from moving further. When the nozzle cover 23 is further moved rearward, the connection protrusion 47a of the connection piece 47 is detached from the front recess 46a. In order to enable such an operation, it is a condition that the driving torque of the driving motor 42 that moves the nozzle cover 23 in the front-rear direction is larger than the load value required for releasing the connecting protrusion 47a.

  As the connecting projection 47a is disengaged from the front recess 46a, the nozzle main body 22 and the nozzle cover 23 are separated from each other, and only the nozzle cover 23 is behind the nozzle main body 22 whose movement is restricted by the rear stopper 51. As a result of the movement, the connecting projection 47a fits into the rear recess 46b. When the connecting projection 47a is completely fitted into the rear recessed portion 46b, the ejection opening 29 is in a state of facing the bidet cleaning ejection port 27. At this time, the nozzle cover 23 abuts on the nozzle cover rear stopper 53 of the nozzle guide 19 and cannot move further rearward. Note that the rotation of the drive motor 42 may be stopped by contacting the nozzle cover rear stopper 53, and the rotation of the drive motor 42 may be stopped by position control based on the rotation speed of the drive motor 42 based on a preset control sequence. It may be stopped.

  When the butt cleaning is completed and the nozzle cover 23 is retracted and the rear end of the nozzle body 22 comes into contact with the rear stopper 51 and stops, or the bidet cleaning is completed, the nozzle cover 23 is retracted and the rear end of the nozzle body 22 is rearward. At the time when it comes into contact with the stopper 51 and stops, the control means starts control of nozzle cleaning. The control means controls the washing water supply means, and starts nozzle cleaning by starting water flow to the washing water supply port 39a. The flow rate is adjusted by the washing water supply means, and the water flow path is switched by the flow path switching valve 37.

  Since the cleaning water ejected from the nozzle cleaning outlet 39 has the nozzle cleaning outlet 39 opened in the laterally tangential direction of the upper portion of the inner diameter of the cleaning enlarged portion 38, the ejected cleaning water flows along the inner wall of the nozzle guide 19 to the nozzle cover. It becomes a swirl flow that swirls and circulates in the circumferential direction through the gap with the main body 25, and dirt on the outer peripheral wall of the nozzle cover 23 and the bidet cleaning jet outlet 27 can be effectively removed. In addition, it is good also as a structure provided with two or more nozzle washing water jet nozzles 37 in the position facing the jet opening 29 substantially. By doing so, the vicinity of the ejection opening 29 where dirt can be relatively easily stored can be intensively cleaned, and a cleaner local cleaning can be realized. Further, by reducing the diameter of the nozzle cleaning water ejection port 39, a water flow with a higher water pressure is ejected, and the cleaning power is improved. Further, by increasing the number of holes, it is possible to effectively clean a wide area.

  As described above, in the present embodiment, the nozzle main body 22 including the buttocks cleaning spout 28 and the bidet cleaning spout 27 that eject the cleaning water, and the flow path that supplies the cleaning water to the respective spouts, A cylindrical nozzle cover 23 that covers the nozzle body 22 and has one ejection opening 29, a connecting means 24 that connects the nozzle body 22 and the nozzle cover 23, and a nozzle guide 19 that houses the nozzle body 22 and the nozzle cover 23 And nozzle drive means 41 for driving advancement and retraction of the nozzle body 22, the nozzle body 22 and the nozzle cover 23 are configured to be slidable with respect to each other, and the nozzle cover 23 so that the ejection opening 29 faces the ejection port to be used. , And the nozzle body 22 having a plurality of jet outlets requires only one jet opening 29, and the dirt is contaminated. Since adhesion tends portion is minimized, cleanliness is improved. Further, since the unused outlet is covered with the nozzle cover 23, the nozzle main body 22 is not contaminated with the cleaning water soiled by the cleaning, which is hygienic.

  In addition, since the ejection opening 29 is the minimum necessary, the appearance is neat and the nozzle cover 23 has a simple configuration, so that the cost can be reduced.

  In addition, since the nozzle body 22 and the nozzle cover 23 are interlocked via the connecting means 24 so that the relative positions can be switched, one nozzle driving means 41 can select the two driving targets respectively. The device can be driven to a position, and the device can be reduced in size and cost.

In the present embodiment, the nozzle drive means 41 employs a transmission mechanism via a gear including a drive motor 42, a worm gear, a transmission gear 43, and a pinion gear 44. However, the present invention is not limited to this. A transmission mechanism such as a chain may be used.

  In the present embodiment, the nozzle cover body 25 is made of stainless steel, but the material is not limited to this, and may be other metal materials having corrosion resistance, inorganic materials such as ceramics, or resin materials. Cleanliness can be further improved by using an antibacterial or antibacterial or water repellent performance added to the above material.

  In the present embodiment, the connecting piece of the connecting means 24 is formed of an elastic metal material. However, the present invention is not limited to this, and an elastic resin material may be used. When the resin material is used, the connecting member of the connecting means 24 can be integrally molded and can be manufactured at low cost.

  Further, in the present embodiment, three channels of the buttocks direct-injection cleaning channel 32, the buttocks swirl cleaning channel 33, and the bidet cleaning channel 34 are formed as cleaning channels. A nozzle cleaning flow path may be provided instead of the nozzle cleaning ejection port 39 installed in the nozzle guide 19 of the casing 16, or a drying air flow path for blowing dry air to dry a human body wet by cleaning may be provided.

  In the present embodiment, the rack 26a that fits the pinion gear 44 is formed on the nozzle rack block 26 that constitutes the nozzle cover 23, the nozzle cover 23 is driven, and the connected nozzle body 22 is pulled. Although it is a structure, it is good also as a structure which comprises a rack in the nozzle body 22 conversely, the nozzle body 22 drives, and the connected nozzle cover 23 is pulled.

  Further, in the present embodiment, the ejection opening 29 opened in the nozzle cover 23 is provided at a position facing the bidet washing ejection port 27 when the nozzle body 22 and the nozzle cover 23 are accommodated. You may provide in the position facing 28. Moreover, the connection receiving part in the connection means 24 may be increased to three places, and you may provide in the position which does not oppose any washing | cleaning jet nozzle. In this way, at the time of storage, all the cleaning jets are covered with the nozzle cover, and dust represented by toilet paper waste does not enter the cleaning port, and can be kept clean.

  Further, in the present embodiment, the nozzle cleaning nozzles are opened in the upper lateral tangential direction of the cleaning enlarged portion, but a plurality of nozzle cleaning nozzles are provided at positions substantially opposite to the nozzle openings when the nozzle cover is stored. It may be opened. By carrying out like this, the jet opening from which the local wash water jets can be concentrated and washed.

  Also, in this embodiment, the sequence is such that cleaning is started after confirming the origin position every time, but the origin position is confirmed only when the main body is turned on, and the position information is stored in the control means. May be. By doing this, the time from when the cleaning start signal is received until the nozzle is actually driven and cleaned is shortened. In addition, a predetermined timing may be set in the control unit, and the origin position may be periodically confirmed according to the timing. As a result, the time until the start of cleaning is shortened, but is automatically corrected when the origin position of the nozzle is deviated.

Here, in order to describe the present embodiment in an easy-to-understand manner, a schematic configuration diagram of the nozzle device is shown in FIG. 33, and the nozzle driving motor 42, nozzle movement amount detection means, and movement direction detection means in FIGS. The configuration of the rotation detection sensor 45 which is the sensor of FIG. 34 is shown in FIGS. 34 (a) and 34 (b). When the washing button of the remote controller 15 which is the washing instruction means of the sanitary washing apparatus is pressed, the motor 42 is rotated in the normal rotation direction by the control means 60, the pinion gear 44 is rotated by the worm gear 61 of the motor 42, and the rack 26 below the nozzles. The rotation is transmitted to the nozzle 22 and the nozzle 22 advances.

  At this time, simultaneously with the rotation of the motor 42, the rotating body 62 with the slit installed in the motor 42 rotates. The rotating body 62 with slit is provided with a slit 63 (FIG. 34) having a part through which light is transmitted and a part through which light is reflected in order to detect the amount of movement of the nozzle. In addition to the slit 63 that can be formed, a slit 64 (FIG. 34) that can detect the nozzle movement direction is provided at an appropriate position. Transmission type photo interrupters 65 and 66 (sensor: FIG. 34) are arranged in the slits 63 and 64, respectively. The control circuit configuration is shown in FIG.

  At the same time that the motor 42 rotates in the forward direction, the slits 63 and 64 also rotate, and each time the slit 63 that can detect the amount of movement of the nozzle crosses the transmissive photointerrupter 65, the output signal 68 of the photointerrupter 65 is shown in FIG. is output as in a). At the same time, each time the slit 64 that can detect the nozzle movement direction crosses another transmissive photointerrupter 66, an output signal 70 of the photointerrupter 66 is output as shown in FIG.

  Simultaneously with the rotation of the motor 42 in the reverse direction, the slits 63 and 64 also rotate, and each time the slit 63 that can detect the amount of movement of the nozzle crosses the transmissive photointerrupter 65, the output signal 68 of the photointerrupter 65 is shown in FIG. c). At the same time, each time the slit 64 that can detect the nozzle moving direction crosses another transmissive photointerrupter 66, an output signal 70 of the photointerrupter 66 is output as shown in FIG.

  At this time, a microcomputer 71 (FIG. 35) for detecting the outputs of the photo interrupters 65 and 66 is arranged, and the microcomputer 71 determines whether or not the motor 42 has operated normally. First, when the motor 42 is in the forward rotation direction, when the input of the nozzle movement amount sensor 65 is a rising pulse, the input of the nozzle movement direction sensor 66 is H input, and the input of the nozzle movement amount sensor 65 is falling. If the input of the nozzle moving direction sensor 65 is L at the time of a pulse, it is determined that the motor is operating normally in the forward rotation direction.

  When the motor 42 is in the reverse rotation direction, when the input of the nozzle movement amount sensor 65 is a rising pulse, the input of the nozzle movement direction sensor 66 is L input, and the input of the nozzle movement amount sensor 65 is a falling pulse. At this time, if the input of the nozzle moving direction sensor 66 is H, it is determined that the nozzle is operating normally in the reverse direction. The determination processing method is shown in FIG.

  If the motor 42 is operated by a force different from the rotation direction of the motor 42 due to an external force, the operation is different from that shown in FIG. 38. For example, although the motor 42 is not outputting, the input of the nozzle movement amount sensor 65 is performed. When H is a rising pulse, the input of the nozzle movement direction sensor 66 is H input, and when the input of the nozzle movement amount sensor 65 is a falling pulse, when the input of the nozzle movement direction sensor 66 is L input, A force is applied in the forward direction.

  In addition, when the input of the nozzle movement amount sensor 65 is a rising pulse, although the motor 42 is not outputting, the input of the nozzle movement direction sensor 66 is L input, and the input of the nozzle movement amount sensor 65 is If the input of the nozzle moving direction sensor 66 is H during the falling pulse, it means that a force is applied in the reverse direction, and it can be determined that the nozzle 22 has moved by an operation other than the motor 42.

Accordingly, the microcomputer 71 can detect the actual movement direction and the actual movement amount with respect to the target set movement direction and the set movement amount, and the control means 60 can detect the nozzle movement amount detection means 63, 65, 71. The movement amount of the cleaning nozzle 22 and the movement direction detection means 64, 6
6 and 71, while detecting whether the movement direction of the cleaning nozzle 22 detected is not deviated from the target setting movement direction and the set movement amount, the cleaning nozzle 22 is driven by a motor to perform a high-precision cleaning operation. can do.

  In the above embodiment, when the movement direction detection means 64, 66, 71 detects that a force different from the movement direction intended by the cleaning nozzle 22 is applied, the control means 60 is opposite to the direction of the cleaning nozzle. Therefore, even when an external force in the direction opposite to the direction in which the cleaning nozzle 22 is driven acts on the cleaning nozzle 22, the movement position of the cleaning nozzle 22 can be corrected.

  Further, in the above embodiment, the interval time between the rise and fall of the input of the nozzle moving direction sensor 66 shown in FIG. 39 is measured.

  As shown in FIG. 39, for example, when an external force is applied to the nozzle 22 even though the motor 42 is not outputting, when the input of the nozzle movement amount sensor 65 is a rising pulse, the nozzle movement direction When the input of the sensor 66 for the nozzle is H input and the input of the sensor 65 for the nozzle movement amount is a falling pulse, when the input of the sensor 66 for the nozzle movement direction is L input, a force is applied in the forward direction. However, the H input time and L input time at that time are measured. As a result, ΔT (T1 + T2 + T3 + T4 + T5 + T6 + T7) can be detected in which direction and at what speed. As a result, it can be judged how much the external force is.

  In this way, since the applied external force can be determined, the energization amount of the motor 42 is controlled in a direction opposite to the external force applied to the nozzle 22 so that the moving torque is more than that, and the nozzle is more reliably detected. 22 movement positions can be corrected.

  The relationship between the moving distance (L) of the nozzle 22 and the moving time (T) of the nozzle 22 is shown in FIG. If the motor does not operate normally and operates in the forward rotation direction or the reverse rotation direction, the speed (V) is determined in advance from the relationship between the movement time (T) and the movement distance (L) (α · L / T) from the relationship shown in FIG. FIG. 41 shows the relationship between the speed (V) and the motor torque (P). As a result, a motor torque (P1) higher than the speed (V1) is output. In advance, the microcomputer 71 outputs the electric energy of the motor 42 so that the torque is equal to or greater than P1, so that it can be corrected appropriately.

  The control means 60 does not immediately end detection and correction of displacement by the sensors 65 and 66 and the microcomputer 71 for detecting the moving amount and detecting the moving direction at the timing of stopping the motor, but for correcting the nozzle movement. A correction is made for a certain period of time. The fixed time necessary for detecting and correcting the deviation is actually a very short time such as 0.1 second or 0.2 second, so that the nozzle drive stops when the user is cleaning. There is no problem that makes you feel strange.

  FIG. 42 shows a flowchart when the nozzle 22 is driven.

  When nozzle driving by the motor 42 is started, the target position of the nozzle 22 is set and the nozzle 22 is moved. The outputs of the movement amount detection and movement direction detection sensors 65 and 66 are input to the microcomputer 71 to determine whether or not they are operating normally, but at the same time as the motor 42 is stopped, the detection by the sensors 65 and 66 is terminated. Instead, it is determined whether the nozzle 22 is normally stopped at the target position for a certain time (a short time of the above-mentioned comma several seconds level) as a normal stop detection timer. As a result, if there is a positional deviation of the nozzle 22, the direction of the positional deviation and the amount of deviation can be corrected.

In the case of the conventional configuration as described in the background art at the beginning, in the case of so-called “move cleaning”, the forward and reverse rotation of the motor 222 is continuously performed and the cleaning nozzle 115 is continuously reciprocated by a predetermined distance to perform butt cleaning and bidet cleaning. However, according to the present embodiment, the motor 42 is continuously rotated in the forward and reverse directions to move the cleaning nozzle 22 at a predetermined distance. When butt cleaning or bidet cleaning is performed continuously in a reciprocating manner, the direction and amount of displacement of the nozzle 22 are determined when the nozzle 22 is reciprocally reversed, and the amount of displacement with respect to the next target position is moved. By correcting, even if the movement position of the nozzle 22 is displaced due to fluctuations in driving resistance or an external force somewhere continuously reciprocating, the nozzle 22 is corrected and driven until the next movement stop position. Conventional problem without such cleaning a position shifted greatly by stacking Les can be maintained accurately reciprocating cleaning of a predetermined position set.

  As described above, the normal detection timer when the motor is stopped is not necessarily limited to detecting the deviation and correcting the deviation due to the normal position movement within the timer time after stopping, but the normality detection timer is used to determine the deviation. It is also included that the normal position movement determined within the timer is performed within the next operation.

  FIG. 43 shows a sensor control circuit capable of improving power saving and component life. When driving of the motor 42 is started, an ON signal is output from the microcomputer 71 to the transistor Q1, and a current flows to the LED side of the photointerptors 65 and 66 which are the sensor for detecting the nozzle movement amount and the sensor for detecting the nozzle movement direction, and the sensor is detected. The transistor Q1 is turned on from the microcomputer 71 until the nozzle position detection is completely completed. When the nozzle position detection is completed and the nozzle position correction is completed, an OFF signal is output from the microcomputer 71 to the transistor Q1, so that no current flows to the LED side of the photointerrupter, and the sensor detection is stopped.

  With this operation, it is not necessary to detect the position when the nozzle 22 is not operating, so that it is not necessary to pass a current through the LEDs of the photointerrupters 65 and 66, and power saving is achieved, and parts of the photointerrupters 65 and 66 are used. Can extend the lifetime of That is, the control means 60 is provided with the power supply control means Q1 for the nozzle movement amount detection means 65 and the movement direction detection means 66, and the nozzle movement amount detection is performed at the same time as the nozzle 22 driving is finished and the correction of the nozzle movement is finished. Since the power supply for control of the means 65 and the moving direction detection means 66 is cut off, power saving and the life of parts can be improved. As described above, in this embodiment, the nozzle 22 driving is ended and the correction of the nozzle movement is completed. At the same time, the control power supply for the nozzle movement amount detection means 65 and the movement direction detection means 66 is shut off. The “shutdown at the end” is not necessarily the same, and after the end, for example, after 5 seconds or 3 minutes, the nozzle 22 drive may be finished and the shutoff may be shut off after a predetermined time after the correction of the nozzle movement is finished.

  FIG. 44 shows a flowchart for determining the manual nozzle operation. When the user operates the nozzle 22 by normal local cleaning, for example, when the nozzle 22 is manually stretched and cleaned when cleaning the nozzle 22, the microcomputer 71 drives the motor 42 by the microcomputer 71 itself. If the movement of the nozzle 22 is detected, it is determined that the nozzle 22 has been manually operated, and the nozzle position correction drive is not performed immediately. Thus, when the user tries to clean the nozzle 22 by manually extending the nozzle 22, there is no problem that the nozzle 22 is immediately retracted by the motor and cannot be washed, and the nozzle 22 is manually pulled out. Can be washed. That is, when the cleaning nozzle 22 is manually expanded and contracted without an instruction from the cleaning instruction means 15, it can be determined that the control means 60 has been manually moved, and correction is not performed immediately. Therefore, the nozzle operation by normal local cleaning is performed. Instead, even if the user manually pulls out the cleaning nozzle to clean the cleaning nozzle 22, the cleaning nozzle 22 can be prevented from being retracted immediately.

Also, if the user continues cleaning the nozzle 22 after the nozzle 22 is not manually returned to the original position and the state continues for a certain period of time (for example, 10 minutes or 20 minutes), the nozzle 22 By notifying that the information has not been returned to the original position on the display unit of the sanitary washing device, it is possible to prompt the user to return to the original position. When it is determined that the control means has been moved manually, the control means notifies the user that the nozzle 22 has not been restored for a certain period of time (for example, 10 minutes or 20 minutes). Can be prevented from being left untreated.

  In addition, if the user does not manually return the nozzle 22 to the original position after cleaning the nozzle 22, and the state continues for a certain period of time (for example, 10 minutes or 20 minutes), By automatically returning the nozzle 22 to the original position by the control means 60, it is possible to leave the cleaning nozzle as it is pulled out, and it is possible to save the trouble of manually returning the cleaning nozzle.

  As described above, the nozzle device according to the present embodiment includes the cleaning nozzle 22 that ejects cleaning water to the human body part, the cleaning instruction means 15 that instructs cleaning, the motor 42 that moves the cleaning nozzle 22 back and forth, and the motor 42, a drive circuit 60 for driving 42, nozzle movement amount detection means 63, 65, 71 for detecting the movement amount of the cleaning nozzle 22, and movement direction detection means 64, 66, 71 for detecting the movement direction of the cleaning nozzle 22, It has means 71 for comparing the designated movement direction and designated movement amount set and stored in advance with the movement direction and movement amount actually moved, and with respect to the target set movement direction and set movement amount, the substantial movement direction and the substantial movement direction. Since the control means 60 intended to move the cleaning nozzle 22 forward / backward according to the movement amount is provided, the control means 60 detects the washing detected by the nozzle movement amount detection means 63, 65, 71. While detecting whether the movement direction of the cleaning nozzle 22 detected by the movement amount and movement direction detection means 64, 66, 71 of the nozzle 22 is not deviated from the target setting movement direction and the target movement amount, the cleaning nozzle 22 is detected. Since the motor is driven by a motor, a highly accurate cleaning operation can be performed.

  Further, when the movement direction detection means 64, 66, 71 detects that a force different from the intended movement direction of the cleaning nozzle 22 is applied, the control means 60 corrects the movement of the cleaning nozzle 22 in the opposite direction. Therefore, even if an external force in the direction opposite to the direction in which the cleaning nozzle 22 is driven acts on the cleaning nozzle 22, the movement position of the cleaning nozzle 22 can be corrected.

  Further, the control means 60 measures the distance between the input pulses of the nozzle movement amount detection means 63, 65, 71 for detecting the movement amount of the nozzle 22, and the movement direction detection means 64, 66, 71 detects the movement amount. By detecting the direction, the nozzle position can be corrected by detecting an external force from the directionality and the moving speed, so that the moving speed of the cleaning nozzle 22 can be corrected.

  In addition, the control means 60 detects a deviation between the target set movement direction and the set movement amount with respect to the actual movement direction and the actual movement amount when the motor 42 is stopped, and takes a certain time for correcting the nozzle movement. Since the correction is provided and correction is performed, the displacement of the cleaning nozzle position can be corrected between the movements of the cleaning nozzle 22.

  Further, the control means 60 is provided with a power supply control means Q1 for the nozzle movement amount detection means 63, 65, 71 and the movement direction detection means 64, 66, 71 to finish the nozzle driving and correct the nozzle movement. When the operation is completed, the power source for controlling the nozzle movement amount detection means 63, 65, 71 and the movement direction detection means 64, 66, 71 is shut off, so that power saving and the life of parts can be improved.

In addition, when the cleaning nozzle 22 is manually expanded and contracted without an instruction from the cleaning instruction unit 15, the control unit 60 can determine that the cleaning nozzle 22 has been manually moved and does not perform correction immediately. Even if the user manually pulls out the cleaning nozzle 22 for cleaning the cleaning nozzle 22 instead of the operation, the cleaning nozzle 22 can be prevented from being retracted immediately.

  In addition, when it is determined that the nozzle 22 has not been returned to a certain time when it is determined that it has been manually moved, the control means 60 notifies the fact that the nozzle 22 has not been returned to the original state. Can be prevented.

  Further, the control means 60 automatically returns the cleaning nozzle 22 to a predetermined position when it is determined that it has been manually moved and the nozzle has not been returned to the original position for a predetermined time, so that the cleaning nozzle 22 can be left untreated. This eliminates the need to manually return the cleaning nozzle 22 to the original position.

  Moreover, it is set as the sanitary washing apparatus provided with the washing water supply means which supplies washing water to an above-described nozzle apparatus, the control means which controls the said nozzle apparatus and the said washing water supply means, and the toilet seat mounted on the upper surface of a toilet bowl. Accordingly, it is possible to perform local cleaning with high accuracy according to the target set movement direction and set movement amount, and to provide a user-friendly sanitary washing device.

  In the present embodiment, the cleaning instruction means for instructing the cleaning has been described as being provided in the remote controller 15, but the present invention is not limited to this and may be provided in the sanitary cleaning apparatus body 10.

  Further, transmission type photo interrupters 65 and 66 are used as sensors for the nozzle movement amount detection means and the movement direction detection means, and the slits 63 and 64 of the rotating body 62 with slits attached to the motor 42 are the transmission type photo interrupter 65, In the above description, the rotation amount and the rotation direction of the motor 42 are detected by passing through the motor 66. However, the present invention is not limited to the transmission type photo interrupter, but a variable resistance type such as a reflection type sensor or a potentiometer. Another type of sensor such as a sensor or a capacitive sensor may be used.

  Further, the configuration in which the sensor unit 45 is provided in the motor 42 has been described. However, the present invention is not limited to this, and the sensor unit 45 is provided in the nozzle 22 or the nozzle rack 26 so that the linear motion of the nozzle 22 or not the rotation of the motor 42 The nozzle position may be directly sensed.

(Embodiment 2)
FIG. 45 is a perspective view of the overall appearance of the nozzle device according to the second embodiment of the present invention, and FIG. 46 is a sectional view of the ejection opening 29 of the nozzle body.

  The present embodiment is different from the first embodiment in the rotation drive means 54 connected to the nozzle body 22 and is otherwise the same as in the first embodiment, and the same configuration is used for the same operation. Reference numerals are assigned, and those in Example 1 are used for the detailed description.

  Since the connection receiving portion 46 that connects the nozzle body 22 and the nozzle cover 23 is provided to have the same cross-sectional shape in the circumferential direction, the connection receiving portion 46 is connected even if the nozzle body 22 rotates. The fitting relationship with the protrusion 47a is not changed, and the connection continues in the same positional relationship. Moreover, the ejection opening 29 opened in the nozzle cover body 25 is a long hole that is long in the circumferential direction. Let the opening angle of this elongated hole be α.

In the state where the butt cleaning or the bidet cleaning is being performed, the rotation driving means 54 is operated by the control means by the control means, and the nozzle body 22 is moved to the position where the butt cleaning jet outlet 28 or the bidet cleaning jet outlet 27 is in the vertically upward position. A certain state is set as a reference position, and it is rotated in the left-right circumferential direction. By making the rotation angle smaller than ½ of the opening angle α to the left and right from the reference position, the washing water is ejected without interfering with the nozzle cover body 25, and the ejected washing water vibrates and can wash a wide range. At the same time, since the jets are scattered, the cleaning feels volume. At this time, the cleaning range and the volume feeling can be adjusted by controlling the rotation speed and the rotation range. Further, the nozzle driving means 41 as well as the rotation driving means 54 can drive the driving motor 42 so as to alternately repeat forward rotation and reverse rotation, thereby realizing a wider range of cleaning.

(Embodiment 3)
FIG. 47 shows a sectional view of the ejection opening 29 of the nozzle body 22 in the third embodiment of the present invention, and FIG. 48 shows a sectional view in a rotated state.

  The present embodiment differs from the second embodiment in that the drying air flow channel 55, the drying air jet 56, the drying air supply port (not shown) and the drying air supply means (not shown) configured in the nozzle body 22 are different. The other components are the same as those in the second embodiment, and the same reference numerals are given to the components having the same action, and those in the first and second embodiments are used for the detailed description.

  The drying air supply means includes a drying fan, a drying heater, and a drying wind tunnel, and the drying wind tunnel communicates with the drying air supply port. The drying fan and the drying heater are configured to blow out hot air having a temperature set by the control means. The drying air outlet 56 is at the same position as the bidet washing outlet 27 with respect to the driving direction of the nozzle body 22 and in a direction in which the hole is directed vertically upward when the nozzle body 22 is rotated by an angle β. is open. By setting β to an angle larger than ½ of the opening angle α of the long hole, the dry air outlet 56 is covered with the nozzle cover 23 during bidet cleaning, and the sewage generated by the bidet cleaning is not directly applied. To be kept. Moreover, since it is the same position as the bidet washing | cleaning jet nozzle 27, it is not necessary to increase the number of the connection receiving parts in the connection means 24, and it becomes a simple structure, Furthermore, the dry wind jet nozzle 56 is comprised ahead of the nozzle main body 22. FIG. Therefore, the protrusion distance of the nozzle cover 23 can be reduced correspondingly, and space saving and cost reduction can be achieved.

  When drying is selected, after confirming the origin position of the nozzle cover 23 as in the bidet cleaning, the drive motor 42 rotates to move forward, and the nozzle body 22 and the nozzle cover 23 are moved forward. As in the case of washing, in the case of drying, after moving to the drying standard position and stopping the drive motor 42, as shown in FIG. That position is the standard position for drying.

  When the nozzle cover 23 reaches the standard position for drying, the control means controls the drying air supply means, and hot air blowing is started. Usually, after washing the buttocks and bidet, the washing water is scattered not only locally but also around the area. For this reason, the nozzle drive means 41 as well as the rotation drive means 54 can drive the drive motor 42 so as to alternately repeat forward rotation and reverse rotation, whereby dry air can be blown over a wider range. In addition, the rotation of the nozzle body 22 and the control of the air flow of the drying air are interlocked so that the air is blown only when the air blowing outlet rotates from the outside to the center part, so that the water droplets on the buttocks are centered. Efficient drying can be realized by blowing the drying air to the central portion collectively at the end.

  As described above, in the nozzle device according to the present invention, the control means is configured such that the nozzle movement amount detected by the nozzle movement amount detection means and the nozzle movement direction detected by the movement direction detection means are the target set movement direction and Since the nozzle is driven by a motor while detecting whether it is not deviated from the set movement amount, a highly accurate cleaning operation can be performed. The present invention can also be applied to various uses such as a cleaning device and a drying device other than the local cleaning used in the sanitary cleaning device.
