Then, at T6, the left and right drive motor 54 is rotated to rotate the nozzle 20 to the right so that the first washing water jet 22 of the nozzle 20 and the opening 29 of the nozzle cover 28 face upward (about +90). °).

  At T7, the front / rear drive motor 53 is operated to move the nozzle to the storage position (backward about 10 mm). Then, the operation is completed at T8.

By the operations from T1 to T8 described above, the angle of the first washing water ejection port 22 for washing with the butt washing can be matched with the opening 29 of the nozzle cover 28, and the ejection direction can be set upward.

  Next, an operation when the user presses the bidet switch 313 of the remote operation device 300 will be described. In this case as well, when the operation is not yet performed, the front-rear direction of the nozzle 20 is disposed at the storage position at the rear end, and the left-right direction of the nozzle 20 is angled with respect to the center position provided on the swinging means 70. It is assumed that it is set.

  At T11, the front / rear drive motor 53 is operated to move to a position where the arm 73 and the stopper a71 do not interfere with each other (about 10 mm forward). At T12, the left / right drive motor 54 is rotated, and the right end angle at which the nozzle 20 hits the stopper b72s. Change the angle to (+ 90 °).

  In T13, the front / rear drive motor 53 is operated to the storage position (about 10 mm rearward), the arm 73 is moved so as to be fitted into the stopper a71, and the nozzle cover 28 is held by the stopper a71.

  Next, at T14, the left and right drive motor 54 is rotated, and the nozzle 20 is rotated to the left so that the second washing water jet port 23 of the nozzle 20 and the opening 29 of the nozzle cover 28 coincide with each other (about −90). °).

  At T15, the front / rear drive motor 53 is operated again to move to a position where the arm 73 and the stopper a71 do not interfere with each other (about 10 mm forward), and at T16, the left / right drive motor 54 is rotated to The nozzle 20 is rotated leftward (about −90 °) so that the outlet 23 and the opening 29 of the nozzle cover 28 face upward.

  At T17, the front / rear drive motor 53 is operated to move the nozzle to the storage position (about 10 mm rearward). Then, the operation is completed at T18.

  By the operations from T11 to T18 described above, the angle of the second cleaning water jet outlet 23 for bidet can be matched with the opening 29 of the nozzle cover 28, and the jet direction can be set upward.

  Next, an operation when the user presses the drying switch 314 of the remote control device 300 will be described. Also in this case, when the operation is not yet performed, the front-rear direction of the nozzle 20 is disposed at the rear end storage position, and the left-right direction of the nozzle 20 is set to an angle at the center position provided in the swinging means 70. It shall be. However, the direction of the opening 29 of the nozzle cover 28 is undetermined.

  At T21, the front / rear drive motor 53 is operated to move to a position where the arm 73 and the stopper a71 do not interfere with each other (about 10 mm forward), and at T22, the left / right drive motor 54 is rotated, and the right end angle at which the nozzle 20 hits the stopper b72s. Change the angle to (+ 90 °). If the opening 29 of the nozzle cover 28 coincides with the first washing water jet outlet 22 at the time T22, the arm 73 hits the stopper b72s, and the relative angle between the nozzle cover 28 and the nozzle 20 changes, and the air jet The angle changes until the outlet 21 and the opening 29 of the nozzle cover 28 coincide.

Next, at T23, the left and right drive motor 54 is reversed to change the angle to the left end angle (−180 °) at which the nozzle 20 hits the stopper b72s on the opposite side. If the opening 29 of the nozzle cover 28 and the second washing water outlet 23 coincide with each other at the time T23, the arm 73 hits the stopper b72s on the opposite side, and the relative angle of the nozzle cover 28 and the nozzle 20 changes. The angle changes until the air outlet 21 and the opening 29 of the nozzle cover 28 coincide.

  As described above, the opening 29 and the air outlet 21 coincide with each other regardless of the direction in which the nozzle faces the opening 29 of the nozzle cover 28.

  Then, at T24, the left and right drive motor 54 is reversed again and rotated so that the air outlet 21 and the opening 29 of the nozzle cover 28 face upward (about + 90 °).

  At T25, the front / rear drive motor 53 is operated to move the nozzle to the storage position (about 10 mm rearward). Then, the operation is completed at T26.

  By the operations from T21 to T26 described above, the angle of the air outlet 21 can be matched with the opening 29 of the nozzle cover 28, and the ejection direction can be set upward.

  Next, the control operation from the butt washing to the drying operation will be described.

  The operation mode of “drying” shown in FIG. 10 is a “quick drying operation” in a state where the drying mode switch 320a of FIG. 2 is selected, and the hot air temperature adjustment switch 340 is a time chart in a state where “medium” is set. is there. This “rapid drying operation” is performed in the first drying operation in which hot air in the drying function is attracted to the surface to be dried while being attracted by pressurized air.

  As shown in FIG. 10, at the time T0 when the operation has not been performed yet, the front-rear direction of the nozzle 20 is disposed at the storage position of the rear end. The left and right direction of the nozzle 20 is set at an angle to a detection position of a position sensor (not shown) that detects the center position provided in the swinging means 70.

  At T1 when the user depresses the butt switch 312 of the remote control device 300, the angle of the first cleaning water jet port 22 for cleaning the butt is matched with the opening 29 of the nozzle cover 28 as described in FIG. The ejection direction is set upward. Here, this operation is omitted. At the same time, when the on-off valve 34 opens and tap water flows into the hot water heating means 31 and a built-in flow sensor (not shown) detects the water flow, energization of the hot water heating means 31 is started, and the heated hot water is Start supplying. At this time, since the nozzle 20 is in the storage position, the unwarmed hot water ejected from the first washing water ejection port 21 hits the inner surface of the guide portion 57 and is discharged into the toilet 600.

  At the time T2 when the temperature of the hot water from the hot water heating means 31 reaches a predetermined temperature (for example, 36 ° C.), the hot water heating means 31 and the on-off valve 34 are stopped and the front / rear drive motor 53 is operated to place the nozzle 20 in the center position. Advance (for example, 100 mm forward). At T3, the operation of the hot water heating means 31 and the on-off valve 34 is restarted, and the cleaning water is jetted onto the surface to be cleaned of the user. Electric power control to the hot water heating means 31 is performed using known PID or FF control so that the temperature detected by a temperature sensor (not shown) for detecting the temperature of the hot water becomes a set temperature (for example, 40 ° C.). The flow rate of the washing water is set to a user's favorite amount by adjusting the valve opening degree of the switching valve 32. As shown in FIG. 11 (a), the wet state of the surface to be cleaned in this butt cleaning is not only the central portion where the cleaning water directly hits but also the water droplets flow to wet the peripheral portion.

  At the time T4 in FIG. 6 where the butt washing is completed and the user presses down the stop switch 311 of the remote control device 300, the hot water heating means 31 and the on-off valve 34 are stopped, and the switching valve 32 is moved to the first washing water jet port. Switching from the 21 direction to the nozzle cleaning means 35 direction stops the cleaning water jet from the nozzle 20, and simultaneously reverses the front / rear drive motor 53 to retract the nozzle 20 to the storage position, thereby completing the cleaning operation.

  In the present embodiment, the operation in the buttocks cleaning has been described, but the basic case is the same when the bidet cleaning for pressing the bidet switch 313 of the remote operation device 300 is pressed. However, in the case of bidet cleaning, the nozzle position and flow rate setting corresponding to the bidet are changed.

  Next, at T5a after a predetermined time from T4, the opening / closing valve 34 is opened, and the cleaning water is supplied from the water inlet 36 in the nozzle cleaning means 35 of FIG. 6, and the cleaning water is sprayed to the nozzle 20 through the cleaning water diffusion portion 38. Clean the attached nozzle. Then, the on-off valve 34 is stopped at T5b in FIG. 10 to finish the nozzle cleaning. This operation pre-cleans the nozzles assuming that a “dry” operation is selected.

  Next, when the user depresses the drying switch 314 of the remote control device 300 at T6, the angle of the air outlet 21 coincides with the opening 29 of the nozzle cover 28 as described in FIG. Set to. Here, this operation is omitted. The heater 43 is energized and the temperature of the heater itself starts to rise. Thus, by energizing the heater 43 before the air fan 41 is operated, the heater is heated in a state where there is little heat dissipation, so the heater temperature can be increased at high speed.

  At the same time, the air pump 51 is operated for a short time (for example, 1 second), and the pressurized air is ejected from the air outlet 21 of the nozzle 20 for a moment. In this operation, the tip of the nozzle 20 is housed in the cleaning chamber 37, and the pressurized air flows at high speed along the nozzle 20 in the cleaning chamber 37 by ejecting pressurized air from the air injection port 21. Water droplets adhering to the surface of the nozzle 20 are blown away. Therefore, reattachment of water droplets to the user is prevented.

  At T7, the operation of the air fan 41 is started, and hot air is blown out from the hot air outlet 42. Since the hot air temperature blown out passes through the heated heater 43, the hot air temperature is high from the beginning. And it sets so that hot air of high temperature (for example, 60 degreeC) may be blown off controlled by the above-mentioned heater heating amount. And it blows with respect to the substantially whole surface of the to-be-dried surface which is a user's washing | cleaning surface from the warm air jet nozzle 42. FIG.

  Thereafter, the front / rear drive motor 53 is operated to advance the nozzle 20 to the most advanced position (for example, 150 mm forward), while the left / right drive motor 54 is operated to change the left / right angle of the nozzle 20 to the right end angle (for example + 50 °). To do.

  At T8, the operation of the air pump 51 is started, and the injection of pressurized air from the air outlet 21 to the surface to be dried is started.

  In the first step from T8 to T9, the operation direction and operation speed of the left and right drive motors 54 and the front and rear drive motors 53 of the drive means 52 are controlled, and the front and rear drive of the nozzle 20 is within a predetermined range (for example, 50 mm to 150 mm forward) At the same time, the left and right angles of the nozzle 20 are slowly driven from the right end angle toward the center angle from the right end angle to a predetermined angle on the right side (for example, + 50 ° to + 20 °). In the operation of the first step, the air jet from the nozzle 20 gradually approaches the center while moving at a high speed in the front-rear direction from a predetermined position on the right side of the surface to be dried of the user. Accordingly, as shown in the operation pattern P1 of FIG. 12, the air jet contact area E gradually moves toward the center G while periodically moving at high speed in the tangential direction of the right end of the surface F to be dried. Therefore, the zigzag movement trajectory is drawn as shown in the figure. As a result, as shown in FIG. 11 (b), since the ejection of the pressurized air is started from the outside sufficiently outside the ejection range of the washing water, the water droplets spread and adhered to the right side of the surface to be dried Can be blown away while collecting.

  At T9 in FIG. 10, the air pump 51 is temporarily stopped, and the left-right angle of the nozzle 20 is changed to the left end angle (for example, −50 °). Then, at T10, the operation of the air pump 51 is resumed and the ejection of pressurized air is started.

  Then, in the second step from T10 to T11, the front-rear drive of the nozzle 20 is reciprocated at a high speed within a predetermined range (for example, 50 mm to 150 mm forward) as in the first step, and at the same time the left-right angle of the nozzle 20 is changed from the left end angle. It is slowly driven toward the central angle from the left-side predetermined angle (for example, −50 ° to −20 °). In the operation of the second step, the air jet from the nozzle 20 gradually moves toward and approaches the central portion while periodically moving at a high speed in the front-rear direction from a predetermined distance on the left side of the surface to be dried of the user. Come. Therefore, as shown in the operation pattern P2 of FIG. 12, the contact area E of the air jet gradually moves toward the center G while periodically moving at high speed in the tangential direction of the left end of the surface F to be dried. Therefore, a zigzag movement trajectory is drawn as shown in the figure. As a result, as shown in FIG. 11C, water droplets spreading and adhering to the left side of the surface to be dried can be blown away while being collected in the central portion direction.

  The water droplets adhering to the surface to be cleaned by the first step and the second step described above remain only around the center.

  Since the buttock of the human body is formed with convex portions on both the left and right sides with respect to the washing center of the anus and penis, both the left and right sides are lower than the washing center when sitting on the toilet seat. Therefore, the washing water tends to wet and spread from side to side, and when an air jet is first applied to the center during drying, the attached water droplets spread greatly to the left and right, and the wet area increases. As described above, since the first step and the second step are blown away while preventing water droplets on the surface to be cleaned from spreading to the left and right, efficient drying can be performed.

  At the end time T11 of the second step, the nozzle 20 is advanced to the most advanced position. Then, in the third step from T11 to T12, while the nozzle 20 is driven back and forth slowly from the most advanced position toward the center, the left and right angles of the nozzle 20 are reciprocated at high speed from the right end angle to the left end angle. In the operation of the third step, the air jet from the nozzle 20 gradually moves closer to the center from a predetermined front position toward the rear while moving at high speed in the left-right direction on the surface to be dried. . Therefore, as shown in the operation pattern P3 of FIG. 13, the contact area E of the air jet gradually innovates toward the center G while performing periodic movement that reciprocates at high speed in the tangential direction of the tip of the surface F to be dried. Since it moves, a zigzag movement trajectory is drawn as shown in the figure. As a result, water droplets remaining in front of the center portion G of the surface to be dried can be blown away while being collected in the direction of the center portion G.

  At T12, the air pump 51 is temporarily stopped, and the position of the nozzle 20 in the front-rear direction is moved to a rear predetermined position (for example, 50 mm forward). Then, at T13, the operation of the air pump 51 is resumed and the ejection of pressurized air is started.

  Then, in a fourth step from T13 to T14, the nozzle 20 is moved back and forth at a high speed from the right end angle to the left end angle at the same time while slowly moving the nozzle 20 forward and backward from the rear predetermined position toward the center. In the operation of the fourth step, the air jet from the nozzle 20 gradually moves closer to the center from a predetermined distance on the rear side while moving at high speed in the left-right direction on the surface to be dried. . Therefore, as shown in an operation pattern P4 in FIG. 13, the contact range E of the air jet gradually moves toward the center G while periodically moving in a tangential direction at the rear end of the surface F to be dried. Since it moves gradually, a zigzag movement trajectory is drawn as shown in the figure. As a result, water droplets remaining behind the central portion G of the surface to be dried can be blown away while being collected in the central portion G direction.

  The water droplets remaining on the surface to be dried by the above first to fourth steps are only the central portion.

  The action on water droplets adhering to the surface to be dried in the first to fourth steps will be described. Since the driving direction of the air jet to the surface to be dried during the operation of each step is sufficiently faster than the moving speed toward the center, the moving speed in the tangential direction is sufficiently faster with respect to the center. The air flow direction which spreads by colliding with the surface to be dried increases the flow component in the direction perpendicular to the substantially tangential direction. Accordingly, the water droplets adhering between the air jet driven in the substantially tangential direction and the central portion are pushed by the air flow perpendicular to the tangential direction and move in the central portion direction. And since an air jet is gradually approached to a center part, it gathers in the center part direction. By performing this movement from the four directions of right, left, front, and rear in the first to fourth steps, the water droplets gather at the center. Thus, the first to fourth steps are steps for collecting water droplets adhering to the surface to be dried at the center of the surface to be dried.

  At T14, the air pump 51 is stopped again, and the front-rear direction position of the nozzle 20 is moved to a predetermined front position (for example, 130 mm forward). Then, at T15, the operation of the air pump 51 is restarted and the ejection of pressurized air is started.

  Then, in the fifth step from T15 to T16, the front-rear drive of the nozzle 20 starts to retreat from a predetermined position in the front, passes through the center, and slowly moves to a predetermined distance behind the center (for example, 50 mm forward). And retreat. At the same time, the left and right angles of the nozzle 20 are reciprocated at high speed from the right end angle to the left end angle. The operation of the fifth step is as follows. The air jet from the nozzle 20 gradually moves backward from a predetermined position in the forward direction while periodically moving in a horizontal direction on the surface to be dried. It approaches the central part, and further moves gradually through the central part to a predetermined position behind it. Therefore, since the position where the air jet strikes the surface to be dried gradually moves from the front through the center and rearward, the water droplets remaining at the center of the surface to be dried can be completely blown away. That is, the fifth step is a process of blowing off the collected water droplets.

  The air pump 51 is stopped at T16, and the front-rear direction of the nozzle 20 is moved to the most advanced position (for example, 150 mm forward). The left-right direction of the nozzle 20 is returned to the center angle.

From T17a to T17b, the nozzle 20 is cleaned by opening the on-off valve 34 while moving the front-rear direction of the nozzle 20 toward the storage position. During this time, washing water is sprayed on the entire nozzle 20 to clean the entire nozzle. At T17b, the on-off valve 34 is stopped and the nozzle cleaning is finished.
When the drying is finished and the user presses the stop switch 311 of the remote control device 300, the operation of the heater 43 is stopped at T18.

  Then, by stopping the air fan 41 at T19, the residual heat of the heater 43 is reduced and the drying operation is completed.

  As mentioned above, weir cleaning, bidet and drying are configured with a single nozzle and the drive means is also shared, so the nozzle installation area can be reduced and the number of parts can be reduced, saving space and reducing costs. Can be realized.

Furthermore, since the pressurized air for drying is ejected from a single nozzle hole, the flow velocity of the air jet can be increased even at a low flow rate, and high drying performance can be obtained even with a small capacity air pump. That is, since the flow velocity of the jet is large, the energy for peeling off the water droplet when the jet hits the water droplet attached to the surface to be dried increases, so that the water droplet can be efficiently blown off.

  In the present embodiment, the configuration in which the washing water ejection position is adjusted by the front, back, left, and right operation switches of the operating means has been described. However, if the same position adjustment is performed when the pressurized air is ejected, the position of the pressurized air You can also make adjustments.

  Further, in this embodiment, cleaning and drying are configured by a single cylinder and the driving means is shared, but these may be configured by independent nozzles and driving means, respectively.

  Furthermore, in this embodiment, the flow rate of the pressurized air is set to 20 to 50 m / s. However, in order to obtain the effect of blowing water droplets, the minimum speed is 10 m / s or more, and the size of the jet contact area is set. The size of the nozzle holes and the number of nozzle holes as elements must be selected in consideration of the capacity of the air pump and the flow rate of the pressurized air.

  Further, in the present embodiment, the first step to the fifth step are sequentially executed, but each step may be repeatedly executed or the order of each step may be changed. Further, the first and second steps may be omitted, and the third and fourth steps may be omitted.

In this embodiment, the heater temperature is increased by energizing the heater before starting the air fan at the start of the drying operation, so that the heater temperature rises at a higher speed. The heater temperature may be increased at a higher speed by providing a soft start function for gradually increasing the air volume.
(Embodiment 2)
Next, a sanitary washing device according to a second embodiment of the present invention will be described.

  The sanitary washing apparatus according to the second embodiment differs from the sanitary washing apparatus according to the first embodiment in the control operation in the following nozzle cleaning. The control operation will be described below.

  FIG. 14 is a time chart of the control operation in the nozzle cleaning operation by the control unit 150 of the sanitary cleaning device according to the second embodiment.

  As shown in FIG. 14, at the time T0 when the nozzle cleaning is not yet started, the buttocks cleaning operation and the pressurized air ejection operation are completed, and the air ejection port 21 is set in the nozzle 20. .

  Nozzle cleaning is started at T1. This timing is the same as in the first embodiment. Here, the front-rear direction of the nozzle 20 is moved to the most advanced position (for example, 150 mm forward).

  From T2 to T3, the nozzle 20 is moved back and forth at high speed from the right end angle to the left end angle at the same time while slowly moving the front and rear direction of the nozzle 20 toward the storage position. At this time, the on-off valve 34 is opened to perform nozzle cleaning. During this time, cleaning water is sprayed over the entire circumference of the nozzle 20 so that the entire nozzle can be cleaned. At T3, the movement of the nozzle 20 to the storage position is completed.

  From T3 to T4, the nozzle 20 performs nozzle cleaning while reciprocating the left and right angles at the storage position. This can be reliably cleaned by increasing the cleaning time of the nozzle tip that is most likely to become dirty.

  At T4, the horizontal direction of the nozzle 20 stops returning to the center angle. And the on-off valve 34 is stopped and nozzle washing | cleaning is complete | finished.

  The air pump 51 is operated for a short time (for example, 1 second) at a time T5 when a water droplet attached to the nozzle 20 naturally falls and settles from T4, and the pressurized air is ejected from the air outlet 21 of the nozzle 20 for a moment. Is done. This operation prevents water droplets adhering to the surface of the nozzle 20 from drying out and sticking to the periphery of the air injection port 21 while the nozzle 20 is in the storage position.

  As described above, the air ejection means according to the present invention and the sanitary washing apparatus provided with the air blowing means efficiently blow off water droplets and dry even with a small amount of air, so that they get wet not only in the sanitary washing apparatus but also in showers and hand washing It can also be applied to dry the body.
