Description

  The present invention relates to a portable toilet provided with a sanitary washing device.

  In the field of portable toilets used by people who are physically disabled or difficult to use a normal toilet, such as the elderly and disabled people, in the field of portable toilets that are used close to where they are indoors, processing after excretion by users and caregivers Various functions have been proposed in order to reduce the burden on the user. For example, there has been proposed a portable toilet equipped with a sanitary washing device that sprays cleaning water on a user's local area after excretion and cleans the user's local area.

  As a portable toilet having such a sanitary washing device, for example, a configuration is proposed in which a user can wash a local area simply by operating an operation switch after using the toilet, and reduce the burden during use. (See Patent Document 1 below).

  That is, as shown in FIG. 22 (drawing corresponding to FIG. 1 of Patent Document 1 below), when the user presses the start switch 821 after finishing the toilet, the hot water stored in the washing water tank 815 is changed. A portable toilet is known that is sprayed from a cleaning nozzle 818, cleans the user's local area, and terminates cleaning when the user presses a stop switch 822 (see Patent Document 1 below).

  In addition, in recent years, after performing local cleaning using a sanitary cleaning device placed on a toilet of a general toilet, taking into account the convenience of general users, not only elderly and disabled persons (After cleaning the surface to be cleaned of the human body), instead of the user removing the water droplets attached to the local area with paper such as toilet paper, a nozzle having a spout that ejects pressurized air at the tip is used. Sanitary washing device (drying) equipped with a drying nozzle that has a configuration that removes water droplets adhering to the local area by spraying pressurized air to the local area and that performs drying (configuration that dries the surface to be dried) Washing toilet seat with function) has been proposed.

  As such a sanitary washing device (washing toilet seat with a drying function), for example, the following configuration is proposed which is intended to dry comfortably in a short time by applying pressurized air to the surface to be dried wet with washing water (See Patent Document 2 below).

  That is, as shown in FIG. 23 (drawing corresponding to FIG. 1 of Patent Document 2 below), when the user performs local cleaning using the local cleaning device and then presses a drying switch (not shown), drying is performed. Sanitary cleaning with a configuration in which the nozzle 918 is sent out from the main body 913 to a predetermined position in the toilet 912 by a circular arc track that is a substantially curved track, and the pressurized air is intermittently injected from the injection hole 936 toward the portion to be cleaned. An apparatus (a washing toilet seat with a drying function) is known (for example, see Patent Document 2 below).

JP 2001-29263 A JP 2006-125193 A

In the conventional portable toilet described in Patent Document 1 described above, the present inventors have used a cleaning nozzle 8.
The washing water adheres as droplets to the user's local area and its surroundings after the washing water is spouted from 18 to the user's local area, and the user or caregiver cleans it with toilet paper etc. It was necessary to wipe off the water droplets attached to the local area and the surrounding area of the later user, and it was found that the effort was burdened by the user or the caregiver.

  On the other hand, the present inventors combine the conventional portable toilet described in Patent Document 1 with the conventional sanitary washing device with a drying function (cleaning toilet seat) described in Patent Document 2 described above. Attempts have been made to solve the problems of the conventional portable toilet described in Japanese Patent Application Laid-Open No. H10-228707.

  However, from the viewpoint of sufficiently reducing the user's discomfort by simply combining the conventional portable toilet described in Patent Document 1 with the conventional drying nozzle described in Patent Document 2 above. The present inventors have found that there is still room for improvement.

  That is, simply by combining the conventional portable toilet described in Patent Document 1 with the conventional drying nozzle described in Patent Document 2, vibration and noise of an air pump that supplies pressurized air to the drying nozzle. In some cases, the user may feel uncomfortable.

  The present invention has been made in view of the above-described problems of the prior art, and even when an air pump is provided, the burden on the user or caregiver is sufficiently reduced and the user's discomfort is sufficiently reduced. An object is to provide a portable toilet that can be reduced.

In order to solve the above-described problems of the prior art, the present invention provides:
A toilet part having a sewage container for storing the excrement of a user having an opening for stool;
A body part that is placed behind the opening of the toilet and includes a device for cleaning and drying the user's local area;
A toilet seat portion that is on the opening of the toilet bowl and is placed in front of the main body portion, is pivotally supported by the main body portion and has a seating surface on which a user sits,
A water supply tank that is provided in the toilet bowl and stores wash water for washing the user's local area;
A washing water jet port for jetting washing water toward the user's local area and the surface to be washed around the user who is placed on the seating surface of the seating part, and pressurized air A cylindrical nozzle portion having an air outlet at the tip portion,
A nozzle drive unit that is arranged in the main body and drives the position of the air jet port so that the pressurized air jetted from the air jet port of the nozzle unit hits an arbitrary position of the surface to be dried;
A first housing disposed within the toilet bowl;
An air pump disposed in the first housing and supplying pressurized air to the nozzle portion;
A first cushioning material disposed between the first housing and the air pump and having elasticity to fix the air pump in the first housing;
A water supply pump disposed in the main body and supplying cleaning water to the nozzle;
A portable toilet having a nozzle drive unit, an air pump, and a control unit that controls at least the operations of the water supply pump is provided.

  As described above, the portable toilet according to the present invention includes the nozzle unit, the nozzle driving unit, the air pump, and the control unit.

Therefore, since the water droplets adhering to the user's local area and its surroundings can be sufficiently blown away with pressurized air, the user or caregiver can use the toilet paper etc. It is no longer necessary to wipe off water droplets adhering to the periphery, and the burden on the user or caregiver can be sufficiently reduced.

  Further, as described above, in the portable toilet of the present invention, the first casing disposed in the toilet bowl and the air pump that is disposed in the first casing and supplies pressurized air to the nozzle section. And a first shock-absorbing material that is disposed between the first housing and the air pump and has elasticity to fix the air pump in the first housing.

  Therefore, the vibration and noise of the air pump can be sufficiently reduced by the first buffer material and the first housing, and the vibration and noise of the air pump can be sufficiently reduced to be transmitted to the user.

  Therefore, according to the portable toilet of the present invention, even when an air pump is provided, a portable toilet that can sufficiently reduce the burden on the user or caregiver and sufficiently reduce the user's discomfort. Will be able to provide.

  Here, in the present invention, the “surface to be cleaned” and the “surface to be dried” are both body surfaces centering on the user's local area.

  In the present invention, in particular, the range of the “surface to be cleaned” is preferably a range that can be contaminated by the user's excretion in and around the user's local area.

  This “surface to be cleaned” is a range of experiments and simulations taking into account the user's body shape distribution, toilet bowl size, toilet bowl shape, wash water discharge volume range, wash water discharge pressure range, etc. You may obtain | require and set beforehand by either of these. In addition, the range of this “surface to be cleaned” is determined every time the user uses the sanitary cleaning device by a sensor that can detect the range that can be soiled by excretion (such as an infrared sensor that detects moisture in the excrement). Alternatively, the optimum range may be obtained by sensing.

  Moreover, it is preferable that the range of the “surface to be dried” in the present invention is a range that can be wetted with the cleaning water when it is cleaned with the cleaning water in and around the user's local area.

  Furthermore, the range (area) of the “surface to be dried” is equal to or greater than the range (area) of the “surface to be cleaned”, and the “surface to be dried” is set to include the entire range of the surface to be cleaned. Is preferred.

  In addition, the “range that can be wetted with cleaning water” usually includes the above-mentioned “surface to be cleaned”, that is, the “region that can be soiled by the user's excretion in the user's local area and its surroundings”. However, if the range to be cleaned is not included in the range that can be wetted with cleaning water, the range of the surface to be dried is the range that can be wetted with cleaning water and the surface to be cleaned. A range including the range is preferable.

  The range of the “to-be-dried surface” is the same as that for the “to-be-cleaned surface” range. The distribution of the user system, the size of the toilet, the shape of the toilet, the discharge amount range of pressurized air, In consideration of the discharge pressure range of air, etc., it may be obtained and set in advance by either experiment or simulation. In addition, the “surface to be dried” range is also used by a sensor that can detect the range that can be wetted with cleaning water (such as an infrared sensor that detects moisture), as in the configuration for determining the range of “surface to be cleaned”. It is good also as a structure which calculates | requires every time a person uses a sanitary washing apparatus, and calculates | requires the optimal range.

In the present invention, the nozzle drive unit includes an advance / retreat drive unit that drives the nozzle unit to advance and retreat in the direction of the axis of the nozzle unit, and a rotation drive unit that rotates the tip of the nozzle unit about the axis as a rotation center. (Claim 2).

  Further, in the present invention, the nozzle drive unit includes an advance / retreat drive unit that drives the nozzle unit to advance and retreat in the direction of the axis of the nozzle unit, and a nozzle unit within a plane that is substantially parallel to the seating surface. It is preferable to have a swing drive unit that swings in the lateral direction intersecting the axis direction.

  Moreover, in this invention, it is preferable that the 1st housing | casing is arrange | positioned in the back of the toilet bowl part and the downward direction of the surface in which the main-body part is mounted (Claim 4).

  Thereby, since the distance of a 1st housing | casing and a main-body part becomes short, the flow path which connects an air pump and a nozzle part can be shortened. Therefore, the configuration in the toilet bowl can be made compact. Moreover, the complexity at the time of assembly can be reduced sufficiently.

  In particular, when the first housing is disposed on the bottom surface behind the toilet unit, the distance between the air pump and the user is increased, so that the vibration of the air pump and the noise due to the vibration of the air pump are sufficiently transmitted to the user. Can be reduced.

  Moreover, in this invention, it is preferable that the 1st housing | casing is arrange | positioned ahead of the toilet bowl part (Claim 5).

  Thereby, since the distance of an air pump and a user leaves | separates, it can fully prevent that the noise by vibration of an air pump and the vibration of an air pump is transmitted to a user.

  Furthermore, in the present invention, it is disposed in the toilet bowl, and is disposed between the second housing that houses the water supply pump, and between the second housing and the water supply pump. It is preferable to have the 2nd shock absorbing material which has the elasticity fixed in 2 housing | casing (Claim 6).

  Thereby, since not only the air pump but also the water supply pump is arranged in the toilet part, the vibration and noise of the water supply pump can be sufficiently reduced by the second casing and the second cushioning material. Discomfort can be sufficiently reduced.

  ADVANTAGE OF THE INVENTION According to this invention, even if it is a case provided with an air pump, while reducing the burden of a user or a caregiver enough, the portable toilet which can fully reduce a user's discomfort can be provided. It becomes like this.

  The toilet seat 400 has a built-in toilet seat heater (not shown) for heating the seating surface. Thereby, the user's buttocks seated on the toilet seat 400 can be warmed.

  The toilet bowl 700 is provided with a water supply tank 500 and a filth container 600 detachably. The toilet unit 700 is provided with an armrest 710 and a backrest 720. Further, the toilet unit 700 includes a first housing 80 (see FIGS. 13 and 14), an air pump 51 (see FIGS. 13 and 14), and a first cushioning material 90 (see FIGS. 13 and 14), which will be described later. Is built-in.

  First, the remote operation device 300 will be described.

  FIG. 2 is a schematic diagram (front view) showing an example of the remote control device 300 in the portable toilet shown in FIG. 1, and FIG. 2 (a) shows a state in which the controller lid 302 of the remote control device 300 is closed. FIG. 2B is a front view showing a state where the controller lid 302 of the remote operation device 300 is closed.

  As shown in FIG. 2 (a), with the controller lid 302 closed, there are drying mode selection switches 320a, 320b, 320c, cleaning strength adjustment switches 322, 323, rhythms on the top of the controller body 301. A switch 324, position adjustment switches 325, 326, 327, and 328 (switches for adjusting the position of the cleaning water ejection port 22 of the nozzle 20) and pattern selection switches 330, 331, and 332 for the cleaning move operation are provided.

Further, with the controller lid 302 closed, a stop switch 311 {all the switches shown in FIGS. 2 (a) and 2 (b) is provided on the outer surface of the controller lid 302 according to each switch. Switch having a function of stopping operation}, drying switch 314,
A butt switch 312 and a bidet switch 313 are provided.

  Next to the position adjustment switches 325, 326, 327, and 328, the washing water ejection position (position of the washing water ejection port 22) that is changed by driving the nozzle portion 20 (advancement / retraction driving and rotation driving) by operating these switches. Is provided. This is composed of a liquid crystal panel, and is configured such that the position of the washing water jet port 22 driven by the nozzle portion 20 is displayed as a point on the liquid crystal panel.

  In the case of this embodiment, when each switch is operated by the user, a predetermined signal corresponding to each switch is wirelessly transmitted from the remote operation device 300 to the main body 200. Further, the control unit 150 (see FIGS. 3 and 4) of the main body 200 described later controls the operation of each component of the main body 200 and the toilet seat 400 based on the signal received from the remote control device 300. It is configured.

  For example, in the case of the present embodiment, when the butt switch 312 or the bidet switch 313 is operated by the user, the control unit 150 is activated, and cleaning water is ejected from the nozzle unit 20 (see FIG. 3) to the user's local area. It is comprised so that.

  Further, in the case of the present embodiment, when the stop switch 311 is operated by the user, the control unit 150 is activated, and the ejection of the washing water from the nozzle unit 20 to the local part of the user is stopped. Yes.

  Further, in the case of this embodiment, when the drying switch 314 is operated by the user, the control unit 150 is activated and applied to the surface to be dried of the user's local area from a pressurized air supply unit 50 (FIG. 4) described later. At the same time as the compressed air is ejected, the warm air is blown out from the warm air supply unit 40 (FIG. 4).

  Further, in the case of the present embodiment, when any one of the three drying mode switches 320a, 320b, and 320c is selected and operated by the user, the above-described dry air blowing condition is blown to the user's local area. It is changed so that it can be arbitrarily selected depending on the use situation and user's preference.

  In FIG. 2A, a drying mode switch 320a is a switch for selecting the “rapid drying operation” mode when it is desired to finish drying in a short time. Further, the drying mode switch 320b is a switch for selecting a “solid drying operation” mode in which the local portion is surely dried to finish it gently. Further, the drying mode switch 320c is a switch for selecting a “warm air drying operation” mode in which only hot air is blown when it is not desired to apply pressurized air.

  Further, around the drying mode switch 320a, the user selects the drying mode switch 320a to visually display to the user that the operation in the “rapid drying operation” mode is performed. An indicator 320a1 is arranged. The indicator 320a1 is configured to blink or light up when the user selects the drying mode switch 320a. In order to notify the user of the driving situation more reliably and quickly, the indicator 320a1 blinks when the user selects the drying mode switch 320a, and the operation in the “rapid drying operation” mode is normally started. When the operation in the “rapid drying operation” mode is not started, it may be turned on or turned on with a different color.

Further, around the drying mode switch 320b, the user selects the drying mode switch 320b to visually display to the user that the operation in the “solid drying operation” mode is being performed. Indicator 320b1 is arranged. The indicator 320b1 is configured to blink or light up when the user selects the drying mode switch 320b. In order to notify the user of the driving situation more reliably and quickly, the indicator 320b1 blinks when the user selects the drying mode switch 320b, and the operation in the “solid dry operation” mode is normally started. It is good also as a structure which changes to the state turned on, and lights up or it lights with a different color, when the driving | operation in a "solid dry operation" mode is not started.

  Further, around the drying mode switch 320c, the user selects the drying mode switch 320c to visually display to the user that the operation in the “warm air drying operation” mode is being performed. The indicator 320c1 is arranged. The indicator 320c1 is configured to blink or light up when the user selects the drying mode switch 320c. In order to notify the user of the driving situation more reliably and quickly, the indicator 320c1 blinks when the user selects the drying mode switch 320c, and the operation in the “warm air drying operation” mode is normally started. Then, the lighting state is changed, and when the operation in the “warm air drying operation” mode is not started, the lighting may be performed or the lighting may be performed with a different color.

  In the case of this embodiment, when the cleaning strength adjustment switches 322 and 323 are operated by the user, the flow rate, pressure, and the like of the cleaning water ejected to the user's local area are adjusted. .

  In the case of the present embodiment, a display unit 322G is provided for visually recognizing the user the sensation intensity of the washing water that changes when the washing strength adjustment switches 322 and 323 are operated. It has been. The display unit 322G is arranged on the left side of the hot air temperature adjustment switch 340 as five bar-shaped indicators extending laterally from the hot air temperature adjustment switch 340.

  Here, the strength of the five levels of washing water is a strength range of washing water that is set in advance in consideration of the usage environment, the user's feeling of the strength of the washing water with respect to the temperature of the hot air, The strength range is divided into five from the higher strength side. In the case of this embodiment, the five bar-shaped indicators of the display unit 322G are arranged in a line from top to bottom in descending order of strength.

  As described above, the strength of the cleaning water is set to the five strength ranges set in advance, so that the user can intuitively and without being aware of setting a specific cleaning water strength value. It will be possible to easily set the strength of comfortable wash water.

  Further, the strength ranges of the five washing waters may be configured such that the user can arbitrarily adjust the initial setting range (initial setting value) according to preference. Further, the temperature region is not limited to the five temperature regions as long as it is divided into two or more.

  The display unit 322G allows the user to recognize the strength of the cleaning water more reliably and easily, and presses the cleaning strength adjustment switches 322 and 323 as necessary to appropriately set the strength of the cleaning water. It becomes possible to adjust more accurately and easily.

  In the case of the present embodiment, when the rhythm switch 324 is operated by the user, the flow rate, pressure, and the like of the wash water ejected to the user's local area are adjusted, and the above five levels of wash water strength are the lowest. A pattern 1 that changes stepwise in the direction in which the intensity increases from the intensity level to the highest intensity level, and a pattern 2 that changes stepwise in the direction in which the intensity decreases from the highest intensity level to the lowest intensity level. The operation is repeated until the stop switch 311 is pressed (until the stop operation is enabled).

  If the timing when the user presses the rhythm switch (the timing when the operation by the rhythm switch is activated) is before the flushing water is ejected, such as before the buttocks switch or bidet switch is pressed, the preset standard flushing water is used. In this case, the cleaning with the cleaning water is started from the pattern 1 or the pattern 2 from the intensity level (for example, the intensity level of the third strongest cleaning water).

  Further, in the case of the present embodiment, when the position adjustment switches 325, 326, 327, and 328 are operated by the user, the position of the cleaning water jet 22 of the cleaning nozzle portion 33 described later becomes a virtual XY orthogonal coordinate plane described later. It is configured so as to be adjusted appropriately in the front / rear and left / right directions (X direction and Y direction). By this operation, the ejection position of the washing water to the user's local area is adjusted. In this way, by converting the drive amount of the cleaning nozzle unit 33 during use into a virtual XY orthogonal coordinate plane and displaying it on the display unit 329, the operation result is easily understood by the user. Yes.

  As shown in FIGS. 21 and 10, this “XY orthogonal coordinate plane” means a substantially smooth surface parallel to the surface F600 of the opening of the filth container 600 with respect to the seating surface F400 of the toilet seat 400 (see FIG. 8). ) (See FIG. 10), it refers to the plane F22 including the flush water outlet 22 substantially parallel to the seating surface F400.

  Next, the XY orthogonal coordinate plane F22 will be described in more detail.

  FIG. 21 illustrates an outline of the relative positional relationship between the virtual XY orthogonal coordinate plane F22 including the cleaning water jet port 22 of the nozzle unit 20 and the seating surface F400 of the toilet seat 400 in the sanitary washing device of FIG. It is a schematic diagram for doing. FIG. 21 is a view of the nozzle unit 20 of the portable toilet 100 shown in FIG. 1 as seen from the side (viewed from the direction of the Y-axis).

  In the case of this embodiment, as shown in FIG. 21, the nozzle portion 20 has an axis A20 direction inclined in advance with respect to the seating surface F400 of the toilet seat 400 (or the surface of the opening of the filth container 600). It is configured to have an angle θ42 (where θ42 is an acute angle).

  Therefore, as shown in FIG. 21, as the nozzle portion 20 moves forward and backward (movement in the direction of the axis A <b> 20), the nozzle portion 20 is also accommodated in the main body portion 200 at the position of the “XY orthogonal coordinate plane” F <b> 22. When the nozzle portion 20 protrudes to the outermost position from the position {the position indicated by "F22 (P1)" in FIG. 21} having the same height as the position P1 (the uppermost position) of the washing water ejection port 22 To the position P2 (the position indicated by “F22 (P2)” in FIG. 21) having the same height as the position P2 (the lowermost position) of the washing water jet port 22 of FIG.

  In other words, the X axis in the XY orthogonal coordinate plane F22 substantially coincides with the axis A20 of the nozzle portion 20 when viewed from the normal direction (Z axis) of the XY orthogonal coordinate plane F22. Of course, the Y axis is an axis orthogonal to the X axis.

  Hereinafter, a control operation in the control unit 150 will be described with reference to FIGS. 8, 9, 10, 11, and 12. FIG.

  FIG. 8 is a time chart of control operations in the “wet cleaning” and “drying” operations by the control unit 150, FIG. 9 is a time chart of control operations in the “washing move” operation of “wet cleaning” by the control unit 150, and FIG. It is typical sectional drawing of the driving | running state of "wet washing" and "drying." FIGS. 11 and 12 are schematic diagrams showing a movement pattern of the jet contact area E on the surface to be dried in the “dry” operation state. Note that the “drying” operation mode shown in FIG. 8 is “rapid drying operation” in a state where the drying mode switch 320a in FIG. 2 is selected, and the hot air temperature adjustment switch 340 is set to “medium”. It is. This “rapid drying operation” is a first drying operation in which hot air in the drying function is attracted by pressurized air and sprayed onto the surface to be dried.

As shown in FIG. 8, at the time of T0 when the operation is not yet performed, the front-rear direction of the nozzle unit 20 (cleaning nozzle unit 33) is disposed at the rear end storage position. The left-right direction of the nozzle unit 20 is set at an angle to a detection position of a position sensor (not shown) that detects the center position provided in the swing drive unit 70. This angle becomes the central angle, and the jet angle of the air jet 21 and the washing water jet 22 is set upward.

  At T <b> 1 when the user depresses the butt switch 312 of the remote control device 300, the water supply pump 34 is activated, and the wash water stored in the water supply tank 500 flows into the hot water heating unit 31. When a built-in flow sensor (not shown) detects a water flow, energization to the hot water heating unit 31 is started, and heated hot water starts to be supplied. At this time, since the switching valve 32 is set in the flow path on the filth container 600 side, hot water that is not sufficiently warmed is discharged into the filth container 600.

  At the time T2 when the temperature of the hot water from the hot water heating unit 31 reaches a predetermined temperature (for example, 36 ° C.), the first electric motor 53 is operated to advance the cleaning nozzle unit 33 to the center position (for example, 100 mm forward). . At T3, the switching water 32 switches the cleaning water to the cleaning nozzle 33 side, and the cleaning water is jetted onto the surface to be cleaned of the user. The power control to the hot water heating unit 31 is performed using known PID or FF control so that the temperature detected by a temperature sensor (not shown) that detects 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. 10 (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. 8 when the butt washing is completed and the user presses down the stop switch 311 of the remote control device 300, the washing water is switched to the filth container 600 side by the switching valve 32, and the washing water jets from the washing nozzle portion 33. At the same time, the energization to the hot water heating unit 31 is stopped, the first electric motor 53 is reversed, and the washing nozzle unit 33 is moved back to the storage position. Then, the water supply pump 34 is stopped at T5, and the cleaning operation is finished.

  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 cleaning nozzle position and flow rate setting corresponding to the bidet are changed.

  Next, when the user depresses the drying switch 314 of the remote control device 300 at T6, the heater 44 is energized and the temperature of the heater itself starts to rise. Thus, by energizing the heater 44 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 raised 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 portion 20 for a moment. This operation prevents the reattachment of water droplets to the user by blowing off water droplets adhering to the surface of the nozzle portion 20 in a state where the nozzle portion 20 is in the storage position.

  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 44, the hot air temperature is high from the beginning. Then, the heater heating amount is controlled, and a high temperature (for example, 60 ° C.) hot air is blown out. 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 first electric motor 53 is operated to advance the nozzle unit 20 to the most advanced position (for example, 150 mm forward), while the second electric motor 54 is operated to set the right and left angle of the nozzle unit 20 to the right end angle (for example, Change the angle to + 50 °. Thereby, the position of the air outlet of the nozzle portion is in a state where the pressurized air has moved to the outer edge portion (E in FIG. 11) of the surface to be dried.

  At T8, the air pump 51 is operated, and pressurized air is ejected from the air ejection port 21 so as to hit the outer edge portion (E in FIG. 11) of the surface to be dried of the user's local area.

  In the first step from T8 to T9, the operation direction and operation speed of the second electric motor 54 and the first electric motor 53 of the nozzle driving unit 52 are controlled, and the front-rear driving of the nozzle unit 20 is performed within a predetermined range (for example, The nozzle unit 20 is slowly driven from the right end angle to the right predetermined angle (for example, + 50 ° to + 20 °) toward the central angle at the same time. In the operation of the first step, the air jet from the nozzle unit 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. Therefore, as shown in the operation pattern P1 in FIG. 11, the air jet contact area E gradually advances toward the center G while periodically moving in the tangential direction of the right end of the surface F to be dried. Since it moves, a zigzag movement trajectory is drawn as shown in the figure. As a result, as shown in FIG. 10 (b), since the ejection of the pressurized air starts from the outside sufficiently outside the ejection range of the washing water, the water droplets spreading and adhering to the right side of the surface to be dried Can be blown away while collecting.

  At T9 in FIG. 8, the air pump 51 is temporarily stopped, and the left-right angle of the nozzle unit 20 is changed to the left end angle (for example, −50 °). At T10, the operation of the air pump 51 is resumed and injection of pressurized air is started.

  Then, in the second step from T10 to T11, the front-rear drive of the nozzle unit 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 unit 20 is set to the left end. Drive slowly from the angle toward the center angle from the left to a predetermined angle (eg, -50 ° to -20 °). The operation of the second step is that the air jet from the nozzle unit 20 gradually moves toward the center while moving periodically at a high speed in the front-rear direction from the predetermined distance on the left side of the surface to be dried of the user. Come on. Therefore, as shown in the operation pattern P2 in FIG. 11, the contact range E of the air jet gradually moves toward the center G while periodically moving in the tangential direction at the left 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, as shown in FIG. 10C, water droplets that spread and adhere to the left side of the surface to be dried can be blown off 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.

  At the end time T11 of the second step, the nozzle unit 20 is advanced to the most advanced position. Then, in the third step from T11 to T12, the front-rear drive of the nozzle unit 20 is slowly retreated from the most advanced position toward the center, and at the same time, the left-right angle of the nozzle unit 20 is reciprocated at high speed from the right end angle to the left end angle. Let The operation of the third step is that the air jet from the nozzle unit 20 gradually approaches the center part from the predetermined front position toward the rear while moving at high speed in the left-right direction on the surface to be dried. come. Therefore, as shown in the operation pattern P3 of FIG. 12, the contact range E of the air jet gradually moves toward the center G while periodically moving in a tangential direction at the tip of the surface F to be dried. Since it moves novelly, 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 portion 20 in the front-rear direction is moved to a rear predetermined position (for example, 50 mm forward). At T13, the operation of the air pump 51 is restarted and injection of pressurized air is started.

  Then, in the fourth step from T13 to T14, while the nozzle unit 20 is slowly driven forward and backward from the rear predetermined position toward the center, the left and right angles of the nozzle unit 20 are reciprocated at high speed from the right end angle to the left end angle at the same time. . The operation of the fourth step is that the air jet from the nozzle section 20 gradually moves closer to the center from a predetermined distance from the rear while moving at high speed in the left-right direction on the surface to be dried. come. Therefore, as shown in the operation pattern P4 of FIG. 12, the contact range E of the air jet flows toward the center G while performing periodic movement that reciprocates at high speed in the tangential direction of the rear end of the surface F to be dried. Since it gradually 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 collides with the surface to be dried and spreads 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 position of the nozzle portion 20 in the front-rear direction is moved to a predetermined position ahead (for example, 130 mm forward). At T15, the operation of the air pump 51 is resumed and injection of pressurized air is started.

  Then, in the fifth step from T15 to T16, the front-rear drive of the nozzle unit 20 starts to retreat from a predetermined position in the front, passes through the central part, and reaches a predetermined distance behind the central part (for example, 50 mm forward). Retreat slowly. At the same time, the left and right angles of the nozzle unit 20 are driven to reciprocate 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 unit 20 gradually moves backward from a predetermined position in the forward direction while periodically moving in the left-right direction on the surface to be dried. And then gradually moves to a predetermined position behind the center. 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.

  At T16, the air pump 51 is stopped, and the front-rear direction of the nozzle unit 20 is moved to the storage position at the rear end. The left-right direction of the nozzle unit 20 is returned to the center angle.

  When the drying is finished and the user presses the stop switch 311 of the remote control device 300, the operation of the heater 44 is stopped at T17.

  Then, by stopping the air fan 41 at T18, the residual heat of the heater 44 is reduced and the drying operation is completed.

In addition, about the ejection range of pressurized air, when the last washing | cleaning process process is bidet washing, it becomes the ejection range set according to bidet washing. Further, when the cleaning position is adjusted from the front 100 mm, for example, the front 110 mm, in the middle of the last cleaning process, the surface to be dried has a wide area from the front 50 mm to 160 mm. Further, in the case where the washing process step is continuously performed as the butt cleaning and the bidet cleaning, the spraying range is set to one drying surface by combining both the drying surfaces, and the front is 50 mm to 180 mm. As for the movement trajectory, the drying process is performed by extending the movement distance with the same pattern of P1 and P2 in FIG. That is, it is possible to efficiently process in a short time so that the movement trajectory does not overlap in the overlapping range between the surface to be dried corresponding to the buttocks cleaning process and the surface to be dried corresponding to the bidet cleaning process.

  Next, the control operation of the “cleaning move” operation of “wet cleaning” shown in FIG. 9 will be described.

  The operation from time T0 to time T3 shown in FIG. 9 is the same as that shown in FIG.

  Wet washing is started at T3, and at time T20, the user depresses the position adjustment switch 325 (FIG. 2) of the remote operation device 300 to adjust the washing position forward. According to this operation, the first electric motor 53 is driven, the nozzle unit 20 is advanced by a predetermined amount (for example, 3 mm forward), and the cleaning position is moved and adjusted. At time T21, the user presses the position adjustment switch 327 (FIG. 2) to adjust the cleaning position to the left. According to this operation, the second electric motor 54 is driven, the nozzle unit 20 is rotated counterclockwise by a predetermined amount (for example, 3 ° to the left), and the cleaning position is moved and adjusted. In this manner, each time the position adjustment switch is pressed, the nozzle unit 20 is driven by a predetermined amount, so that the movement can be adjusted to the cleaning position desired by the user.

  At time T22 and time T23, the user depresses the “narrow” switch 332 (FIG. 2) of the cleaning move of the remote control device 300. From T22 to T23, the operation direction and operation speed of the second electric motor 54 and the first motor 53 of the nozzle driving unit 52 are controlled, and the front-rear driving of the nozzle unit 20 is performed for a predetermined distance (for example, from the set position to the front-rear direction). The reciprocating operation is performed at a medium speed (for example, 1 Hz) at 8 mm), and at the same time, the left and right angles of the nozzle unit 20 are reciprocated at a high speed (for example, 5 Hz) at a predetermined angle (for example, a set angle ± 3 °). Therefore, the washing water reciprocates back and forth while finely shaking the user's local part from side to side along a preset two-dimensional movement trajectory.

  This washing move operation improves the feeling of washing spread and improves washing performance.

  At time T24 and time T25, the user depresses the “middle” switch 331 (FIG. 2) of the cleaning move of the remote control device 300. From T24 to T25, the same operation as in the case of the above-described cleaning move “narrow” is performed. The difference from the above-mentioned “narrow” is that the set value of the left and right reciprocal angles of the nozzle portion 20 is widened. For example, the cleaning range can be widened by setting the left and right angles to a set angle ± 5 °.

  At time T26 and time T27, the user depresses the “wide” switch 331 (FIG. 2) of the cleaning move of the remote control device 300. Also from T26 to T27, the same operation as in the case of the above-described cleaning movement “narrow” is performed. The difference from the above-mentioned “middle” is that the set value of the left and right reciprocal angles of the nozzle portion 20 is further widened. For example, the cleaning range can be further widened by setting the left and right angles to a set angle ± 7 °.

  At the time T28 when the butt washing is completed and the user presses down the stop switch 311 of the remote control device 300, the same end operation as described in FIG. 8 is performed. The set value adjusted for the cleaning position is stored until this end operation, and even if the above-described cleaning move operation is performed in the middle, the set value is returned to the set position when the cleaning move operation is completed.
