Description

  The present invention relates to a sanitary washing device for washing a local part of a user (human body).

  More specifically, the present invention relates to a sanitary washing apparatus having a drying function for drying a wet user's buttocks by removing the water droplets attached to the wet user's buttocks by washing with air. .

  In the field of a sanitary washing apparatus that is installed on the upper surface of a toilet bowl and cleans a user's local area, configurations having various functions have been proposed in order to realize washing according to the user's preference.

  For example, after cleaning the user's local area using a sanitary cleaning device, the user ejects pressurized air at the tip instead of removing the water droplets attached to the local area with paper such as toilet paper. A sanitary washing apparatus equipped with an air nozzle unit device that removes water droplets adhering to the local part by spraying pressurized air toward the local part using a nozzle part having a nozzle and drying the wet local part Has been proposed.

  As a conventional sanitary washing apparatus having such an air nozzle unit, for example, a sanitary washing apparatus (sanitary toilet seat apparatus) having the configuration shown in FIG. 16 is known (for example, Patent Document 1 and Claim 4 below). , Claim 9, paragraph numbers 0013 and 0018, FIG. 5 etc.).

  When the conventional sanitary washing device shown in FIG. 16 is dried by applying pressurized air toward the surface to be dried (surface to be blown) including the local part of the user that has become wet with the washing water. It has a structure intended to prevent the water droplets of the cleaning water adhering to the blower surface from spreading more than necessary and to collect water droplets in one place to improve water droplet removal efficiency.

  That is, the sanitary washing apparatus shown in FIG. 16 gradually applies pressurized air by applying pressurized air from the outer edge portion of the surface to be dried when drying the surface to be dried wet with cleaning water. An air nozzle portion provided with means called air discharge area variable means (see the air discharge area variable means 44 in FIG. 5 of the patent document) that removes water droplets so that the water droplets are gathered at the center of the air flow. It has the structure which mounts an apparatus (refer the air nozzle part apparatus 4 in FIG. 2 of patent document).

JP 2000-192527 A

  However, even in the conventional sanitary washing apparatus described in Patent Document 1 described above, the “region including the user's local area wet with the washing water” (in the “surface to be dried” in the present invention described later) There is still room for improvement from the viewpoint of sufficiently reducing user discomfort when the contained area) is dried with pressurized air.

That is, in the conventional sanitary washing device described in Patent Document 1 described above, after the cleaning of the user's local area is completed, in order to remove water droplets attached to the area including the user's local area in a wet state, In the case of jetting air, the jet of pressurized air started from the “outer edge portion” of the region including the user's local area in a wet state.

  Hereinafter, it will be described in detail that in the conventional sanitary washing apparatus, the ejection of the pressurized air is started from the “outer edge portion” of the wet area of the user's buttocks.

  Generally, a user's buttocks (buttock) is in a state in which a convex portion protruding downward is formed around the washing center portion with respect to the washing center portion (local portions such as anus and penis and the vicinity thereof). (Refer to the region of the cleaning center portion P in the user's buttocks R shown in FIG. 9 described later and the convex portion Q around it).

  That is, when the user sits on the toilet seat of the sanitary washing device, the user's buttocks are located in a state where the surrounding convex portion is lower than the center of the washing (so that it is close to the floor on which the sanitary washing device is placed). Is in the position).

  Therefore, when the user's buttocks are washed, even if the washing water is discharged aiming at the washing center, the washing water flows downward from the washing center along the surface of the convex portion. As a result, the region of the human buttock that is wetted by the cleaning water extends not only to the cleaning center that is directly exposed to the cleaning water, but also to the vicinity of the top of the convex portion around the cleaning center (shown in FIG. 9 described later). (Refer to the area “Dry surface F”)

  From the above, conventionally, when the user's buttocks are washed with washing water and then dried by applying pressurized air, not only the washing center but also the water droplets that adhere to the surroundings are further outside. In order to prevent the air from spreading, a drying method has been adopted in which pressurized air starts to be applied from an “outer edge portion” of an area including a user's local area in a wet state.

  For example, pressurized air has begun to be applied from an outer edge portion that is a predetermined distance (for example, 50 mm) away from the cleaning center. Furthermore, in the past, after applying pressurized air from the outer edge part, a method of drying where water is collected in one place by gradually applying the pressurized air toward the cleaning center and narrowing the air blowing range. Was adopted.

  When pressurized air begins to be applied to the area including the user's local area in such a wet state from the “outer edge portion”, the user mistakenly recognizes that the position of the jet is displaced at that time. The present inventors have found that a feeling of discomfort (discomfort) is felt. Furthermore, if the user who feels uncomfortable shifts the position of the buttocks on the seating surface of the toilet seat, the water droplets adhering to the surface to be dried cannot be removed efficiently and may not be sufficiently removed. The inventors have found.

  The present invention has been made in view of the above-described problems of the prior art. After the surface to be cleaned is cleaned with cleaning water, the surface of the user who is wet with the cleaning water is dried with pressurized air. An object of the present invention is to provide a sanitary washing device capable of removing water droplets more reliably while sufficiently reducing discomfort.

In order to solve the above-described problems of the prior art, the present invention provides:
Wash water outlet for jetting cleaning water toward the user's local area and the surrounding surface to be cleaned, and air for jetting pressurized air toward the user's local area and its surrounding surface to be dried A cylindrical nozzle part having a spout and a tip part;
A cleaning water supply unit for supplying cleaning water to the nozzle unit;
A pressurized air supply section for supplying pressurized air to the nozzle section;
A support unit that is integrally connected to the nozzle unit, supports the nozzle unit so as to be rotatable about its axis, and supports the nozzle unit so as to be movable back and forth in the direction of the axis;
An advancing / retreating drive unit that is fixed to the support part and drives the nozzle part to advance / retreat in the axial direction;
A rotation drive unit that is fixed to the support unit and that rotates the nozzle unit about the axis as a rotation center;
A controller that controls the operation of the cleaning water supply unit, the pressurized air supply unit, the advance / retreat drive unit, and the rotation drive unit;
At least,
The work process controlled by the control unit includes a cleaning process for cleaning the surface to be cleaned by jetting cleaning water from the cleaning water outlet, and pressurized air from the air outlet after the cleaning process. A drying process for removing water droplets adhering to the dry surface, and
In the drying process,
The control unit controls at least one of the advancing / retreating driving unit and the rotation driving unit to position the air outlet of the nozzle unit, and the pressurized air ejected from the air outlet includes the user's local part. A first step of moving to a preset pressurized air ejection start position so as to hit the center of the surface;
A second step of ejecting pressurized air from the pressurized air ejection start position toward the central portion;
After the second step, the control unit controls at least one of the advancing / retreating driving unit and the rotation driving unit to position the air outlet of the nozzle part, and the pressurized air ejected from the air outlet is the surface to be dried. A third step of moving to a preset water droplet removal start position so as to hit the outer edge portion of
A fourth step of ejecting pressurized air from the water droplet removal start position toward the outer edge portion;
Is further included,
The flow rate of the pressurized air in the second step is set lower than the flow rate of the pressurized air in the fourth step,
A sanitary washing device is provided (claim 1).

  As described above, in the sanitary washing device of the present invention (Claim 1), in the drying process step, the pressurized air ejected from the air ejection port is previously applied to the center of the surface to be dried including the user's local part. Is set. Furthermore, in the drying process, the flow rate of the pressurized air in the second step is set lower than the flow rate of the pressurized air in the fourth step.

  Therefore, since the dry air begins to be applied relatively weakly from the center of the surface to be dried including the user's local area, the user does not feel the above-mentioned uncomfortable feeling (uncomfortable feeling) and the user does not blow out. Without misrecognizing that the position is shifted, it is possible to recognize that the satellite cleaning device has started to dry the surface to be dried by the user without making a mistake. Further, this can more reliably prevent the user from shifting the position of the buttocks on the seating surface of the toilet seat.

  Moreover, according to the sanitary washing apparatus of the present invention, the flow rate of the pressurized air in the second step is set lower than the flow rate of the pressurized air in the fourth step, so that the surface to be dried is in the second step. It is also easy to prevent the adhering water droplets from spreading more than necessary.

  That is, according to the sanitary washing device of the present invention, after the surface to be cleaned is cleaned with cleaning water, the user's discomfort when drying the surface to be dried wet with cleaning water with pressurized air is sufficiently reduced. On the other hand, it is possible to provide a sanitary washing apparatus that can remove water droplets more reliably.

  Further, according to the sanitary washing device of the present invention, it is possible to prevent the water droplets of the washing water adhering to the surface to be dried from spreading more than necessary in the drying process.

  Furthermore, from the viewpoint of obtaining the effect of the present invention more reliably, in the sanitary washing device of the present invention, the flow rate of the pressurized air in the fourth step is a flow rate that can remove water droplets adhering to the surface to be dried in the vicinity of the surface to be dried. It is preferable that the flow rate of the pressurized air in the second step is less than the minimum value.

  Thereby, it becomes possible to more reliably prevent the water droplets adhering to the surface to be dried in the second step from spreading beyond the range of the pressurized air ejected from the air ejection port of the nozzle portion. This also makes it possible to more efficiently and sufficiently remove water droplets attached to the surface to be dried by pressurized air in the fourth step.

  The above “minimum value of the flow velocity at which water droplets adhering to the surface to be dried can be removed” is the usage environment {temperature, relative humidity, the condition of the surface to be dried (the thickness of the hair, the body hair) The length, body hair density, sebum secretion amount, sweat secretion amount, body temperature, etc.), water droplets attached to the surface to be dried evaporate from the surface to be dried, move on the surface to be dried, or It can be experimentally determined in advance by measuring the flow rate of the pressurized air as it leaves (falls) from the dry surface.

  Furthermore, in addition to the viewpoint of considering the minimum value of the flow velocity at which water droplets adhering to the surface to be dried can be removed in the fourth step and the second step described above (Claim 2), the pressurized air further strikes the surface to be dried. From the viewpoint of making the feeling of use given to the user more reliable and the like, in the sanitary washing device of the present invention, the flow rate of the pressurized air in the fourth step is 20 to 100 m / s in the vicinity of the surface to be dried. preferable.

  With this configuration, it is possible to more reliably and efficiently remove water droplets attached to the surface to be dried by the pressurized air in the fourth step.

  Here, by setting the flow rate of the pressurized air in the fourth step to 100 m / s or less in the vicinity of the surface to be dried, pain or cold caused by the pressure air hitting the surface to be dried during the drying process in the fourth step. It is possible to more reliably prevent the user from feeling such discomfort.

  Further, by setting the flow rate of the pressurized air in the fourth step to 20 m / s or more in the vicinity of the surface to be dried, the feeling of use given to the user when the pressurized air hits the surface to be dried is more surely comfortable. On the other hand, it is possible to move water droplets adhering to the surface to be dried more smoothly and reliably from the outer edge portion of the surface to be dried to the center of the surface to be dried.

  In the fourth step, when a part of the water droplets adhering to the surface to be dried evaporates when moving from the outer edge portion of the surface to be dried to the center of the surface to be dried by the pressurized air, part of the water droplets In some cases, the surface may be separated (dropped) from the surface to be dried.

  In addition to the viewpoint of considering the minimum value of the flow velocity at which water droplets adhering to the surface to be dried can be removed in the fourth step and the second step described above (Claim 2), the pressurized air further strikes the surface to be dried. In the sanitary washing device according to the present invention, the flow rate of the pressurized air in the second step is 5 m / s or more and 20 m / s in the vicinity of the surface to be dried. It is preferable that it is less than.

  In addition, adopting the range of the flow rate of the pressurized air in the second step is used when adopting a configuration in which the flow rate of the pressurized air in the fourth step is 20 to 100 m / s in the vicinity of the surface to be dried. Is also preferable.

  With this configuration, it is possible to more reliably prevent water droplets adhering to the surface to be dried from expanding beyond the range in which pressurized air is ejected from the air ejection port of the nozzle portion.

Here, in this case, by setting the flow rate of the pressurized air in the second step to 5 m / s or more in the vicinity of the surface to be dried, dry air is being applied to the center of the surface to be dried including the local part of the user. This makes it possible for the user to recognize more reliably. For this reason, the user is not required to feel the discomfort (discomfort) described above, and the user wishes to dry the surface to be dried without causing the user to misrecognize that the ejection position is misaligned. It becomes possible to recognize more reliably that the apparatus is starting to dry without error.

  In addition, when the flow rate of the pressurized air in the second step is less than 20 m / s in the vicinity of the surface to be dried, when the dry air is beginning to be applied to the center of the surface to be dried including the user's local part, Therefore, it is possible to more reliably prevent water droplets adhering to the surface to be dried from spreading out from the center of the surface to be dried. By more reliably preventing water droplets adhering to the surface to be dried from spreading from the center of the surface to be dried, in the fourth step, water droplets are collected while collecting from the outer edge portion of the surface to be dried to the central portion. Can be done more easily and reliably.

  Here, in the present invention, the “surface to be cleaned” and the “surface to be dried” both indicate 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 excretion of the user in the local area of the user (human body) and its surroundings. The range of the “surface to be cleaned” includes the distribution of the body shape of the user (user group), the size of the toilet, the shape of the toilet, the discharge amount range per unit time of the wash water, the discharge pressure range of the wash water, etc. In consideration, it may be obtained and set in advance by either experiment or simulation.

  The range of the “surface to be cleaned” is determined by the central portion of the “surface to be cleaned” by a sensor or the like that can detect the range contaminated by excretion (such as an infrared sensor that detects moisture in the excrement). Thus, each time the user uses the sanitary cleaning device, the center portion of the “surface to be cleaned” may be sensed to obtain the optimum range.

  Furthermore, the range of the “surface to be dried” is the same as the range of the “surface to be cleaned”, and the distribution of the user's body shape, the size of the toilet, the shape of the toilet, and the unit time of pressurized air In consideration of the discharge amount range, the discharge pressure range of pressurized air, and the like, 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.

  Furthermore, in the sanitary washing apparatus of the present invention, the area of the “surface to be dried” is equal to or larger than the 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. It is preferable.

  As a result, the surface to be cleaned, which is exposed to the cleaning water, is positioned within the surface to be dried in a wider range than this, and water droplets adhering to the user's buttocks can be more reliably removed.

  Further, in the sanitary washing device of the present invention, the range of the surface to be cleaned is a range that includes a range that can be contaminated by the user's excretion in the local area of the user and its surroundings, The range is preferably a range including the range that can be soiled by excretion and the entire range of the user's local area and its surroundings that can be wetted by the cleaning water by the cleaning process.

Thereby, it is possible to ensure that the washing water is applied to the soiled part due to excretion, and it is possible to more reliably clean the dirt adhering to the user's buttocks. In addition, the surface to be cleaned, which is exposed to the cleaning water, is positioned within the surface to be dried in a wider range than this, so that water droplets adhering to the user's buttocks can be more reliably removed.

  Further, in the sanitary washing device of the present invention, the center portion of the surface to be dried including the user's local part in the first step is set in a range obtained in advance so that the user does not feel uncomfortable in the second step. It may be.

  Accordingly, the pressurized air does not cause the user to feel uncomfortable feeling (uncomfortable feeling) more reliably even when the pressurized air hits the surface to be dried in the second step, and the user does not misrecognize that the position of the ejection is misaligned. In addition, it is possible to more surely make it possible to recognize that the satellite cleaning device has started to dry the surface to be dried by the user without making a mistake. Furthermore, this makes it possible to more reliably prevent the user from shifting the position of the buttocks on the seating surface of the toilet seat.

  Here, in the sanitary washing device of the present invention, the `` center part of the surface to be dried including the user's local area '' or `` the range in which the user does not feel uncomfortable '' in the first step where the dry air begins to be relatively weakly applied, As in the case of obtaining the range of “surface to be dried” and “surface to be cleaned” described above, the distribution of the user's body shape, the size of the toilet, the shape of the toilet, and the discharge amount of compressed air per unit time In consideration of the range, the discharge pressure range of the pressurized air, etc., it can be obtained and set in advance by either experiment or simulation.

  Further, in the sanitary washing device of the present invention, in the case of the above-described configuration, at the end of the washing treatment step, the range that the washing water hits on the surface to be washed is outside the setting that does not cause the previously felt discomfort. If it is within the range, the control unit corrects the center of the surface to be dried including the user's local part so as to include a range outside the setting, and adjusts the compressed air ejection start position in accordance with the correction. You may comprise.

  Thereby, at the end of the cleaning treatment process, even if the range where the cleaning water hits the surface to be cleaned is outside the set range outside the range that does not cause the previously felt discomfort, the following You will be able to do it more reliably.

  That is, without causing the user to feel uncomfortable (uncomfortable feeling) more reliably even when the pressurized air hits the surface to be dried in the second step, and without causing the user to misrecognize that the position of the ejection is misaligned. Thus, it is possible to more surely make it possible to recognize that the satellite cleaning device has started to dry the surface to be dried by the user without making a mistake. Furthermore, this makes it possible to more reliably prevent the user from shifting the position of the buttocks on the seating surface of the toilet seat.

  In addition, with such a configuration, when the user performs cleaning by combining a plurality of cleaning processing steps before the drying processing step (for example, cleaning at a desired position according to the sitting posture on the toilet seat). Adjusting the position of the nozzle part during washing so that it hits water, performing so-called “cleaning move” mode cleaning while moving the nozzle part over a wide range, for example, so-called “wet cleaning” mode cleaning In the case of performing cleaning in the so-called “bidet cleaning” mode after the execution of the step, after the surface to be cleaned is cleaned with cleaning water, the surface to be dried wet with the cleaning water is dried with pressurized air. Water droplets can be more reliably removed while sufficiently reducing the discomfort of the user.

  In the sanitary washing device of the present invention, in the fourth step, it is preferable that the pressurized air be ejected from the outer edge portion of the surface to be dried toward the central portion including the user's local portion.

  As a result, water droplets adhering to the surface to be cleaned and the surface to be dried due to cleaning can be more reliably prevented from spreading from the outer edge portion of the surface to be dried to the center portion of the surface to be dried and more reliably. Water droplets can be removed by moving more reliably.

  Furthermore, in the sanitary washing device of the present invention, the toilet seat is mounted on a toilet having an opening for stool and has a seating surface on which a user sits, and is fixed to the support portion and is attached to the control portion. It is preferable that the control further includes a swing drive unit that swings in a lateral direction intersecting with the axial direction of the nozzle unit within a plane substantially parallel to the seating surface.

  By further providing this rocking drive unit, the relative position of the cleaning water outlet of the nozzle part with respect to the surface to be cleaned in the cleaning process and the relative position of the air outlet of the nozzle part with respect to the surface to be dried in the drying process It is possible to adjust more precisely, and it becomes possible to remove water droplets adhering to the surface to be dried more easily and more reliably.

  According to the present invention, after cleaning the surface to be cleaned with cleaning water, water droplets can be more reliably reduced while sufficiently reducing user discomfort when drying the surface to be dried wet with cleaning water with pressurized air. Therefore, it becomes possible to provide a sanitary washing device that can remove water. Moreover, according to this invention, it can also prevent the water droplet of the washing water adhering to the to-be-dried surface in a drying process process spreading more than necessary.

It is configured.

  In FIG. 2A, the 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 the “solid” drying operation mode in which the local portion is surely dried and the local portion is finished smoothly. Further, the drying mode switch 320c is a switch for selecting a “warm air” drying operation mode in which only warm 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 indicate to the user that the operation is being performed in the “rapid” drying operation mode. 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. If the operation in the “rapid” drying operation mode is not started, it may be lit or lit in 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 is being performed in the “solid” drying operation mode. 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” drying operation mode is normally started.

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 FIG. 2A, cleaning strength adjustment switches 322 and 323 and a rhythm switch 324 are arranged on the right side of the drying mode switches 320a, 320b, and 320c.

  In the case of the present embodiment, when the cleaning strength adjustment switches 322 and 323 are operated by the user, the nozzle unit 20, the cleaning water supply unit 30, the driving unit 52, and the control unit 150, which will be described later, are activated and the local part of the user is operated. The flow rate, pressure, and the like of the cleaning water ejected on the water 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 cleaning strength adjustment switches 322 and 323 as five bar-shaped indicators extending laterally from the cleaning strength adjustment switches 322 and 323.

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. Moreover, the intensity | strength area | region should just be divided into two or more, and is not limited to five demonstrated by this embodiment.

  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.

  As shown in FIG. 2A, a rhythm switch 324 is disposed below the cleaning strength adjustment switches 322 and 323.

  In the case of this embodiment, when the rhythm switch 324 is operated by the user, the nozzle unit 20, the cleaning water supply unit 30, the driving unit 52, and the control unit 150, which will be described later, are activated and are washed out to the user's local area. The flow rate and pressure of the water are adjusted, and the above-mentioned five levels of wash water intensity change in a stepwise manner from the lowest intensity level to the highest intensity level, and the highest intensity level. The pattern 2 that changes stepwise in the direction in which the intensity decreases from the minimum intensity level to the lowest intensity level 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 324 (the timing when the operation by the rhythm switch is activated) is before the washing water is jetted, such as before the butt switch 312 and the bidet switch 313 are pressed, a preset standard is set. The cleaning water is started to be washed from the pattern 1 or the pattern 2 from the strength level of the washing water (for example, the strength level of the third strongest washing water).

  In FIG. 2A, position adjustment switches 325, 326, 327, and 328 are arranged on the right side of the cleaning strength adjustment switches 322 and 323 and the rhythm switch 324.

  In the case of the present embodiment, when the position adjustment switches 325, 326, 327, and 328 are operated by the user, the drive unit 52 and the control unit 150 described later are activated, and the cleaning water jet of the nozzle unit 20 (see FIG. 3) is activated. The position of the outlet 22 is configured to be adjusted appropriately in the front-rear and left-right directions (X direction Y direction) on a virtual XY orthogonal coordinate plane described later.

  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. 1, 6, and 9 to 13, this “XY orthogonal coordinate plane” means that the seating surface F 400 of the toilet seat 400 is substantially smooth and parallel to the surface F 600 of the opening of the toilet 600. When the surface (see FIG. 6) is assumed (see FIG. 6) (see FIG. 6), the washing water jet 22 substantially parallel to the seating surface F400.
A plane F22 including

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

  FIG. 6 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. 6 is also a view of the nozzle unit 20 of the sanitary washing device 100 shown in FIG. 1 as viewed from the side (showing the XZ plane as viewed from the direction of the Y axis).

  In the case of the present embodiment, as shown in FIG. 6, the nozzle portion 20 has an inclination angle that is set in advance with respect to the seating surface F400 of the toilet seat 400 (or the surface of the opening of the toilet 600). It is configured to have θ42 (where θ42 is an acute angle).

  Therefore, as shown in FIG. 6, as the nozzle portion 20 advances and retreats (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. 6} having the same height as the position P1 (the uppermost position) of the cleaning water jet 22 To the position P2 (the position indicated by “F22 (P2)” in FIG. 6) having the same height as the position P2 (the lowest position) of the washing water ejection port 22 in 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.

  For example, the washing water outlet 22 of the nozzle unit 20 is moved from the position P30 {(x, y, z) = (x1, y1, z1)} to P40 {(x, y, z) = (x2, y1) shown in FIG. , Z2)}, the cleaning water jet port 22 actually moves the distance from P30 to P40 on the XZ plane, but the distance from P30 to P50 on the XY orthogonal coordinate plane ( This means that the distance corresponding to the orthogonal projection of “side from P30 to P40” to “side from P30 to P50” is moved.

  Therefore, when the washing water jet port 22 of the nozzle unit 20 moves from the position P30 to P50 shown in FIG. 6, the distance on the display unit 329 is “side from P30 to P50” on the virtual XY orthogonal coordinate plane.

  Next, the control unit 150 will be described.

  The control unit 150 of the main body 200 is based on signals transmitted from the remote operation device 300, the human body detection sensor 700 and the seating sensor 610, the toilet seat temperature detection sensor (not shown), and the room temperature detection sensor (not shown). It has the structure which controls operation | movement of each part (The washing water supply part 30, the warm air supply part 40, the pressurized air supply part 50, the drive part 52, etc.) of the sanitary washing apparatus 100.

  As shown in FIG. 3, when performing a cleaning process for cleaning a user's local area with cleaning water, the control unit 150 mainly controls the cleaning water supply unit 30 and the drive unit 52. More specifically, the control unit 150 mainly controls operations of the on-off valve 34, the hot water heating unit 31, the switching valve 32, the advance / retreat drive motor 53, and the rotation drive motor 54.

  As shown in FIG. 4, when performing the drying process process which dries the user's local part after washing | cleaning, the control part 150 mainly controls the warm air supply part 40 and the pressurized air supply part 50. FIG. More specifically, the control unit 150 controls the operations of the air pump 51, the advance / retreat drive motor 53, the rotation drive motor 54, the air fan 41, and the heater 44 based on a detection signal of a room temperature detection sensor (not shown).

  In the present embodiment, when the drying process is performed, when the drying switch 314 is pressed and a signal instructing the start of the drying operation is received, the control unit 150 performs the hot air supply unit 40 and the pressurized air supply unit 50. Then, drive signals are output to the drive unit 52 so that they can be driven.

  And the control part 150 is in any one of the following three drying operation modes about the drive of the warm air supply part 40 and the pressurized air supply part 50 in the 2nd process of the drying process mentioned later, and a 4th process. It is configured to be able to execute the mode.

That is, the flow of warm air blown by the warm air supply unit 40 is merged with and mixed with the jet of pressurized air ejected from the nozzle unit 20, and the mixed fluid of warm air and pressurized air is applied to the surface to be dried. “First drying operation mode” to be injected, “second drying operation mode” in which only the warm air supply unit 40 is driven and only the warm air is blown to the surface to be dried, and a mixed fluid of warm air and pressurized air Is the same as the first drying operation mode in that it is sprayed onto the surface to be dried, but has a “third drying operation mode” for performing a drying operation for a set time longer than the first drying operation mode. .

  Here, the first drying operation mode is a drying operation control corresponding to the “rapid” drying operation mode described above. The first drying operation mode is drying operation control that is executed when the user presses (selects) the drying mode switch 320a shown in FIG.

  The second drying operation mode is a drying operation control corresponding to the “warm air” drying operation mode described above. The second drying operation mode is a drying operation control executed when the user presses (selects) the drying mode switch 320c shown in FIG.

  Furthermore, the third drying operation mode is a setting time (second setting time) in which the execution time of the drying operation in the first drying operation mode is longer than a predetermined setting time (first setting time). This is a drying operation control corresponding to the “solid” drying operation mode described above. The third drying operation mode is a drying operation control executed when the user presses (selects) the drying mode switch 320b shown in FIG.

[Control operation by control unit 150]
Hereinafter, a preferred example of the control operation by the control unit 150 in the satellite cleaning device 100 will be described with reference to FIGS.

  FIG. 7 shows the control operation of the control unit 150 when performing the “wet washing” operation in the “cleaning process” and the “drying” operation in the “drying process” using the sanitary washing device 100 shown in FIG. It is a time chart which shows. FIG. 8 is a time chart showing the control operation of the control unit 150 when performing the “move” operation of the “wet cleaning” operation using the sanitary washing apparatus 100 shown in FIG. Further, FIG. 9 is a schematic diagram showing an example of the operation of the nozzle unit 20 when performing the “wet washing” operation using the sanitary washing device 100 shown in FIG.

  10 and 11 are schematic views showing an example of the operation of the air outlet 21 of the nozzle unit 20 when the “drying” operation using the sanitary washing device 100 shown in FIG. 1 is performed. Further, FIG. 12 shows the inside of the surface to be dried F of the air jet of the pressurized air ejected from the air ejection port 21 of the nozzle unit 20 when performing the “drying” operation using the sanitary washing device 100 shown in FIG. It is a schematic diagram which shows the movement pattern by. Further, FIG. 13 shows a surface to be dried F of an air jet of pressurized air ejected from the air ejection port 21 of the nozzle unit 20 when performing a “drying” operation using the sanitary washing device 100 shown in FIG. It is a schematic diagram which shows the movement pattern in the inside.

  First, a suitable example of the control operation by the control unit 150 shown in FIG. 7 will be described.

  In the time chart shown in FIG. 7, the operation mode when the drying switch 314 of the remote control device 300 is pressed (selected) is the drying mode switch 320 a shown in FIG. The “rapid” drying operation mode (first drying operation mode) when pressed (selected) is shown. Further, the time chart shown in FIG. 7 shows a case where the hot air temperature by the hot air temperature adjustment switch 340 is set to the “medium” level.

(1) During standby As shown in FIG. 7, at time T0 when the user does not operate the remote control device 300, the nozzle unit 20 moves in the forward / backward direction (the direction of the dotted line AB shown in FIG. 5). Is disposed at a storage position in the main body 200. More specifically, in this storage position, the position of the washing water outlet of the nozzle portion 20 is at the position P1 shown in FIG.

  At the time T0, the rotation direction of the nozzle portion 20 (the direction of the dotted line CD shown in FIG. 5) is set to a preset standby position (standby angle).

  Based on information obtained from a position sensor (not shown) provided in the rotation drive unit 70, the control unit 150 always sets the standby position (standby angle) to substantially coincide with a preset position (angle). The rotation driving unit 70 is controlled and adjusted. The standby position (standby angle) is such that, for example, the central axis of the air outlet 21 (the direction in which the pressurized air is ejected) and the central axis of the cleaning water outlet 22 (the direction in which the cleaning water is ejected) of the seating surface F400. It may be set so as to face the direction (upward direction, for example, the Z-axis direction shown in FIGS. 1, 6, and 9 to 12).

(2) Cleaning processing step Next, when the user depresses the butt switch 312 of the remote control device 300, the control unit 150 starts control for performing butt cleaning (timing T1 shown in FIG. 7). . First, a detection signal indicating that the switch 312 has been pressed from the remote operation device 300 is transmitted to the control unit 150. Next, the control part 150 which received the signal controls the on-off valve 34 in the washing water supply part 30 shown in FIG.

  Thereby, tap water begins to be supplied to the hot water heating unit 31 through the cleaning water supply line L30.

  Next, when a flow sensor (not shown) built in the hot water heating unit 31 detects a water flow, a detection signal of the water flow is transmitted to the control unit 150. Next, the control part 150 which received the detection signal of the water flow performs control to start energization heating of a heater (not shown) of the heat exchanger in the hot water heating part 31.

  Thereby, warm water begins to be supplied from the warm water heating unit 31 into the downstream water supply line L30.

  Here, when the temperature of the hot water is not sufficiently raised to a temperature suitable for cleaning, the control unit 150 controls the switching valve 32 so that the water flowing in the cleaning water supply line L30 is supplied to the switching valve 32. It switches to the connected washing water discharge line L32, and it adjusts so that it may discharge in the toilet bowl 600. FIG.

  Further, when the temperature of the warm water is sufficiently raised to a temperature suitable for cleaning (for example, 36 ° C.), the control unit 150 controls the switching valve 32 so that the water flowing in the cleaning water supply line L30 is discharged. It adjusts so that it may supply to the water tube 26 connected to the switching valve 32. FIG.

  Note that the control of the switching valve 32 by the control unit 150 may be performed by directly detecting the water temperature by a temperature detection means (not shown) such as a temperature sensor. You may be set as the structure performed by detecting progress of the time required for the heating until it becomes temperature suitable for washing | cleaning. Further, the control of the switching valve 32 by the control unit 150 may be configured to be performed by detecting the amount of water flow until reaching a temperature suitable for water washing obtained by experiment or simulation.

Next, when the temperature of the hot water coming out of the hot water heating unit 31 reaches a temperature suitable for cleaning (eg, 36 ° C.) (timing T2 shown in FIG. 7), the control unit 150 operates the advance / retreat drive motor 53. The nozzle portion 20 is advanced to a position just below the region of the cleaning center portion P (region of the center portion G in FIG. 9) of the surface to be cleaned including the user's local area (for example, from B of the dotted line AB shown in FIG. Advancing 100 mm in the direction toward A or in the direction of the axis A20 of the nozzle portion 20 shown in FIG.

  When the forward movement of the nozzle 20 to the position is completed (timing T3 shown in FIG. 7), the control unit 150 controls the switching valve 32 so that the supply destination of cleaning water (hot water) is the nozzle. Switch to section 20. As a result, the cleaning water is ejected from the cleaning water outlet 22 of the nozzle portion 20 toward the surface to be cleaned of the user.

  Here, the electric power control to the hot water heating unit 31 after the washing water is jetted is a setting that the detection temperature of a temperature sensor (not shown) that detects the temperature of the hot water coming out of the hot water heating unit 31 is set by the user. It is performed using known PID or FF control so that the temperature (for example, 40 ° C.) is reached.

  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.

  Further, for example, during the operation of washing the user's local area with the washing water ejected from the washing water jet port 22, the position adjustment switches 325, 326, 327, and 328 of the remote control device 300 (FIG. 2). When the position adjustment switch 327 (“front”), 328 (“rear”) is operated by the user, the control unit 150 receives the signal and outputs a drive signal to the advance / retreat drive motor 53. As a result, the advance / retreat drive motor 53 is driven at a predetermined rotational speed for a predetermined time, and the cleaning water jet port 22 advances / retreats (front / rear direction) {the arrow A direction (forward direction) and the arrow B direction (reverse direction) shown in FIG. ) Position} is adjusted.

  When the user operates the position adjustment switches 325 and 326, the control unit 150 receives the signal and outputs a drive signal to the rotation drive motor 54. As a result, the rotation drive motor 54 is driven at a predetermined rotation speed for a predetermined time, and the rotation angle (left-right direction) of the cleaning water jet 22 {arrow C direction (right rotation direction) and arrow D direction shown in FIG. (Rotation angle in the left rotation direction) is adjusted.

  Here, in this cleaning process, the surface to be cleaned (the range of the user's buttocks R that is wetted by the cleaning water) is excreted by the user in and around the local area of the user's buttocks R. Is set to a range that can be stained. More specifically, the surface to be cleaned is set so as to include not only the cleaning central portion P in the user's buttocks R but also a part of the surrounding convex portion Q.

  Therefore, immediately after the end of the cleaning process, as shown in FIG. 9, the user's collar R is wet with the cleaning water not only to the cleaning central part P but also to a part of the surrounding convex part Q. Become.

  When the cleaning process (in this case, “wet cleaning”) is completed and the user depresses the stop switch 311 of the remote control device 300 (timing T4 shown in FIG. 7), the control unit 150 causes the switching valve 32 to operate. Is controlled so that the water flowing in the washing water supply line L30 is switched to the washing water discharge line L32 connected to the switching valve 32 and discharged into the toilet 600, and the washing water jet from the nozzle portion 20 is controlled. Stop.

  At the same time, the control unit 150 stops energizing the hot water heating unit 31. And the control part 150 reversely rotates the advancing / retreating drive motor 53 to retract the nozzle part 20 to the storage position described above.

  Thereafter, the control unit 150 closes the on-off valve 34 to shut off the water flow, and finishes the cleaning operation (timing T5 shown in FIG. 7).

  In the above description, the cleaning operation control by the control unit 150 in “wet cleaning” has been described. However, the control operation sequence based on the cleaning operation control by the control unit 150 in “bidet cleaning” is the above-described “wet cleaning”. This is the same as the cleaning operation control in “Cleaning”.

  However, in the case of the cleaning operation control by the control unit 150 in the “bidet cleaning”, the user starts pressing the bidet switch 313 of the remote control device 300 shown in FIG. The water flow rate setting is changed to a position suitable for bidet cleaning and the cleaning water flow rate setting.

  Here, the user's buttocks R (buttock) immediately after the end of the cleaning process is wet with the cleaning water as described below.

  As shown in FIG. 9, generally, the user's buttocks R (buttock) is directed downward around the cleaning center P with respect to the region of the cleaning center P (local areas such as the anus and penis and the vicinity thereof). The protruding convex portion Q is formed.

  That is, when the user sits on the toilet seat 400 of the sanitary washing device 100, the user's buttocks R are located in a state in which the surrounding convex portion Q is positioned lower than the region of the washing center P (the sanitary washing device 100). Is located close to the floor on which it is placed.

  Therefore, when the user's buttocks R are cleaned, even if the cleaning water is discharged while aiming at the cleaning center P, the cleaning water flows downward from the cleaning center P along the surface of the projection Q.

  As a result, the region wetted by the cleaning water in the heel portion R of the human body extends not only to the region of the cleaning center P where the cleaning water directly hits, but also to the vicinity of the apex of the convex portion Q around the cleaning center P.

(3) Drying treatment step In this drying treatment step, the region including the entire region of the human body's buttocks R wetted by the cleaning water is defined as the surface to be dried F, and the cleaning water in the surface to be dried F is removed. .

  First, when the user depresses the drying switch 314 of the remote control device 300, the control unit 150 starts energizing the heater 44 and starts increasing the temperature of the heater (timing T6 shown in FIG. 7).

  Thus, by starting energization to the heater 44 and starting heat generation before starting the operation of the air fan 41, the heater is heated in a state where there is little heat radiation from the heater to the outside, so the heater temperature is increased at a high speed. Can be raised.

  Simultaneously with the above control, the control unit 150 causes the air pump 51 to operate for a short time (for example, 1 second). As a result, the pressurized air is ejected from the air outlet 21 of the nozzle portion 20 for a moment. With this control operation, it is possible to blow off water droplets attached to the surface of the nozzle unit 20 in a state where the nozzle unit 20 is in the storage position, and it is possible to prevent the water droplets from reattaching to the user.

  Next, the control unit 150 starts the operation of the air fan 41 and performs control to blow out warm air from the warm air outlet 42 (timing T7 shown in FIG. 7). In this case, since the hot air temperature blown out from the hot air outlet 42 passes through the heated heater 44, the hot air temperature is suitable for drying from the beginning.

  For example, it is set so that warm air having a warm air temperature suitable for drying (for example, 60 ° C.) is blown out. Then, warm air is blown from the warm air outlet 42 to substantially the entire surface F to be dried of the user.

(3A) 1st process Then, the control part 150 operates the advancing / retreating drive motor 53, and the position of the air ejection port 21 of the nozzle part 20 is a user's local part by the pressurized air ejected from the said air ejection port 21. Up to a pressurized air ejection start position (for example, the same position as the cleaning water ejection position in the cleaning process, for example, a position advanced 100 mm forward from the storage position) so as to hit the central portion of the surface F to be dried Control to move is performed (first step).

  In addition, in this 1st process, about the movement position in the case of moving the nozzle part 20 for the drying after bidet washing | cleaning, the preset pressurized air ejection start position (for example, storage position) corresponding to bidet washing | cleaning is used. Position forward 130 mm from the front).

  Further, in the first process, when the butt cleaning and the bidet cleaning are continuously performed, the pressurized air ejection start position is a position corresponding to the cleaning process performed later between the butt cleaning and the bidet cleaning. To decide.

  Thereby, the nozzle part 20 will be in the state which moved to the position which can eject pressurized air to center part P (area | region of center part G in FIG. 12) of the to-be-dried surface F including a user's local part in FIG.

(3B) 2nd process Next, the control part 150 starts the operation | movement which ejects pressurized air from the pressurized air ejection start position toward center part P of the to-be-dried surface F containing a user's local part (2nd process). Process).

  Specifically, the control unit 150 operates the air pump 51, and the region of the center portion P of the surface to be dried F including the user's local portion in FIG. 9 from the air outlet 21 of the nozzle portion 20 (the center portion in FIG. 12). Pressurized air is ejected so as to hit the region G) (timing T8 shown in FIG. 8).

  Here, the flow rate of the pressurized air in the second step is set lower than the flow rate of the pressurized air in the fourth step which will be described later.

  More specifically, the flow rate of the pressurized air is set lower than the minimum value of the flow rate at which water droplets attached to the surface to be dried can be removed. For example, it is set to 15 m / s.

  Thus, in this 2nd process, dry air begins to be comparatively weakly applied from the area | region of the center part P (area | region of center part G in FIG. 12) of the to-be-dried surface F including the user's local part in FIG. Therefore, the surface to be dried F that the user wants to dry without causing the user to feel the above-mentioned uncomfortable feeling (uncomfortable feeling) and not causing the user to misrecognize that the position of the ejection is misaligned. It can be recognized that the satellite cleaning device 100 is starting to dry without error.

  Moreover, it can prevent more reliably that a user will slip | deviate the position of the collar part R (tail) in the seating surface F400 of the toilet seat part 400 by this.

  Further, this causes the washing water to unnecessarily diffuse from the region of the central portion P (region of the central portion G in FIG. 12) of the surface to be dried F including the user's local portion in FIG. Can be sufficiently prevented from expanding.

  Here, in the second step, from the viewpoint of obtaining the above-described effect more reliably, the flow rate of the pressurized air in the second step is preferably 5 m / s or more and less than 20 m / s in the vicinity of the surface to be dried. In addition, the suitable numerical range of the flow velocity of this pressurized air was calculated | required by experiment which the present inventors mention later.

  Here, in this case, by setting the flow rate of the pressurized air in the second step to 5 m / s or more in the vicinity of the surface to be dried F, the central portion P of the surface to be dried F including the local portion of the user's buttocks R is formed. When dry air is beginning to be applied to the region (the region of the central portion G in FIG. 12), the user can be surely recognized.

  For this reason, the user is not required to feel the discomfort (discomfort) described above, and the user wishes to dry the surface to be dried without causing the user to misrecognize that the ejection position is misaligned. It becomes possible to recognize more reliably that the apparatus is starting to dry without error.

  Further, by setting the flow rate of the pressurized air in the second step to less than 20 m / s in the vicinity of the surface to be dried, the region of the center portion P of the surface to be dried F including the user's local portion (the center G in FIG. 12). When the dry air is started to be applied to the region, water droplets adhering to the surface to be dried are more reliably recognized by the user while the region of the central portion P of the surface F to be dried (center portion G in FIG. 12). It is possible to more reliably prevent the outer area from expanding outside the area.

  By preventing the water droplets adhering to the surface to be dried from spreading out from the region of the central portion P of the surface to be dried F (region of the central portion G in FIG. 12) more securely, Water droplets can be more easily and reliably removed while collecting from the outer edge portion of the surface to be dried to the central portion.

  Here, both “surface to be cleaned” and “surface F to be dried” indicate body surfaces centering on the local area of the user's buttocks R.

  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 (human body).

  The range of the “surface to be cleaned” includes the body shape distribution of the user (user group), the size of the toilet 600, the shape of the toilet 600, the discharge amount range per unit time of the cleaning water, and the discharge pressure range of the cleaning water. In consideration of the above, it may be obtained and set in advance by either experiment or simulation.

  The range of the “surface to be cleaned” is determined by the central portion of the “surface to be cleaned” by a sensor or the like that can detect the range contaminated by excretion (such as an infrared sensor that detects moisture in the excrement). Thus, each time the user uses the sanitary cleaning device 100, the center portion of the “surface to be cleaned” may be sensed to obtain the optimum range.

  Further, the range of the “surface F to be dried” is the same as the case of obtaining the range of the “surface to be cleaned”, the distribution of the body shape of the user, the size of the toilet 600, the shape of the toilet 600, the compressed air In consideration of the discharge amount range per unit time, the discharge pressure range of pressurized air, and the like, it may be obtained and set in advance by either experiment or simulation.

  In addition, the range of the “surface to be dried F” is similar to the configuration for obtaining the range of the “surface to be cleaned” by a sensor that can detect a range that can be wetted with cleaning water (an infrared sensor that detects moisture). It is good also as a structure which senses whenever a user uses a sanitary washing apparatus, and calculates | requires the optimal range.

  Furthermore, in the sanitary washing apparatus 100, the area of the “surface to be dried F” is equal to or larger than the area of the “surface to be cleaned”, and the “surface to be dried F” is set to include the entire range of the surface to be cleaned. It is preferable.

  As a result, the surface to be cleaned, which is exposed to the cleaning water, is positioned within the surface to be dried F in a wider range than this, and water droplets adhering to the user's buttocks R can be more reliably removed. .

  Furthermore, in the sanitary washing apparatus 100, the range of the surface to be cleaned is a range that includes a range that can be found by the user's excretion in the local area of the user's buttocks R and its surroundings. The range of F is preferably a range including the range that can be soiled by excretion and the entire range of the user's local area and its surroundings that can be wetted by the cleaning water by the cleaning process.

  Thereby, it is possible to ensure that the washing water is applied to the soiled part due to excretion, and it is possible to more reliably clean the dirt adhering to the user's buttocks R. In addition, the surface to be cleaned to which the cleaning water hits is positioned in the surface to be dried F in a wider range than this, and water droplets adhering to the user's buttocks can be more reliably removed.

  More specifically, in the sanitary washing device 100, the movement range (range in the advancing / retreating direction and the range of the rotation angle) of the washing water ejection port 22 is the movement range (the range in the advancing / retreating direction) of the air ejection port 21 described later. The range is sufficiently narrower than the range of the rotation angle), and the moving range of the washing water outlet 22 is adjusted to be included in the moving range of the air outlet 21.

  Thereby, the range of the surface to be cleaned can be included in the surface to be dried without protruding from the range of the surface to be dried F, and the range in which the user can get wet with the cleaning water (or the range that actually gets wet). ) Can be easily and more reliably removed by drying with water under pressure.

  From the above viewpoint, for example, the surface to be cleaned of a user who is exposed to cleaning water is 20 mm from the region of the cleaning center P (local area such as the anus and penis and its vicinity, the region P in FIG. 9) in the advance direction of the advancing and retracting direction. When set in a range of 20 mm in the backward direction and 10 mm in the rotation direction (left and right direction) orthogonal to the forward and backward direction, that is, 40 mm × 20 mm with the region of the cleaning center P as a substantially geometric center. When setting to a substantially rectangular area, the surface to be dried F is set as follows.

  That is, in the case of the above-described surface to be cleaned, for example, the surface F to be dried of the user who is exposed to pressurized air is 50 mm from the drying center G (the region of the center G in FIG. Is set to a range of 50 mm in the rotation direction (left-right direction) orthogonal to the forward / backward direction, that is, the drying center point G (the region of the central portion G in FIG. 12) is set as the substantially geometric center. Set to a substantially rectangular area of 100 mm × 100 mm. Accordingly, it is possible to more easily and more effectively obtain the water droplet removal effect by the pressurized air while suppressing unnecessary spread of the wettable range (or actually wetted range) by the cleaning water.

  In the sanitary washing device 100, the area of the central portion P of the surface to be dried F including the user's local area in the first step (the area of the central portion G in FIG. 12) is determined in advance by the user. You may set in the range which does not feel discomfort in two processes.

Thus, in the second step, the pressurized air does not cause the user to feel uncomfortable feeling (uncomfortable feeling) even when the surface to be dried F, and the user is misrecognized that the position of the ejection is misaligned. Accordingly, it is possible to more surely recognize that the satellite cleaning device 100 starts to dry the surface to be dried F that the user wants to dry without making a mistake.

  Further, this makes it possible to more reliably prevent the user from shifting the position of the buttocks R (tail) on the seating surface F400 of the toilet seat 400.

  Here, in the sanitary washing apparatus 100, “region of the central portion P of the surface F to be dried including the local part of the user (region of the central portion G in FIG. 12) in the first step in which the dry air starts to be relatively weakly applied. ”Or“ range in which no discomfort is felt ”is the same as the case of obtaining the ranges of“ surface to be dried F ”and“ surface to be cleaned ”described above, the distribution of the body shape of the user, the size of the toilet, the toilet In consideration of the shape, the discharge amount range of pressurized air per unit time, the discharge pressure range of pressurized air, etc., it can be obtained and set in advance by either experiment or simulation.

  Further, in the sanitary washing device 100, in the case of the above-described configuration, at the end of the washing treatment process, the range where the washing water hits the surface to be washed is a range outside the range that does not cause the previously felt discomfort. In this case, the control unit corrects the region of the central portion P of the surface to be dried F including the user's local portion (the region of the central portion G in FIG. 12) so as to include a range outside the setting. At the same time, it may be configured to adjust the position where the pressurized air starts to be ejected.

  Thereby, at the end of the cleaning treatment process, even if the range where the cleaning water hits the surface to be cleaned is outside the set range outside the range that does not cause the previously felt discomfort, the following You will be able to do it more reliably.

  In other words, in the second step, the pressurized air does not cause the user to feel uncomfortable (uncomfortable feeling) more reliably even when the surface to be dried F, and the user does not misrecognize that the position of the ejection is misaligned. In addition, it is possible to more surely make it possible to recognize that the satellite cleaning device has started to dry the surface to be dried by the user without making a mistake.

  Further, this makes it possible to more reliably prevent the user from shifting the position of the buttocks R (tail) on the seating surface F400 of the toilet seat 400.

  In addition, with such a configuration, when the user performs cleaning by combining a plurality of cleaning processing steps before the drying processing step (for example, a preferred position corresponding to the sitting posture on the toilet seat 400) The position of the nozzle unit 20 is adjusted during the cleaning so that the cleaning water hits the nozzle, the so-called “cleaning move” mode of cleaning is performed while the nozzle unit 20 is moved in a wide range, for example, the so-called “wet cleaning” Even if the so-called “bide cleaning” mode is performed after the “mode cleaning” is performed, the surface to be cleaned is cleaned with cleaning water, and then the surface to be dried F wet with the cleaning water is added. Water droplets can be more reliably removed while sufficiently reducing user discomfort during drying with compressed air.

(3C) Third Step Next, the control unit 150 controls at least one of the advance / retreat drive motor 53 and the rotation drive motor 54 to change the position of the air outlet 21 of the nozzle unit 20 to the air outlet. 21 is moved to a water droplet removal start position (for example, a position indicated by E in FIG. 12) set in advance so that the pressurized air ejected from 21 hits the outer edge portion of the surface F to be dried (third step).

More specifically, the control unit 150 drives the rotation drive motor 54 while driving the advance / retreat drive motor 53 to advance the nozzle unit 20 to the most advanced position (for example, a position advanced 150 mm forward from the storage position). By driving, the rotation angle of the nozzle unit 20 is rotated to an angle (for example, + 50 °) which becomes the right end of the right turn.

(3D) 4th process Next, the control part 150 starts the driving | operation of the air pump 51, and toward the outer edge part of the to-be-dried surface F, a water droplet removal start position (for example, position shown by E in FIG. 12). The injection of pressurized air is started from the air outlet 21 of the nozzle unit 20 positioned at (fourth step, timing T9 shown in FIG. 7).

  The flow rate of the pressurized air in the fourth step is higher than the flow rate of the pressurized air in the second step, and is equal to or higher than the minimum value of the flow rate at which water droplets attached to the surface to be dried F can be removed in the vicinity of the surface to be dried F. Is set. For example, the flow rate of the pressurized air is set to 30 m / s.

As a result, it is possible to more efficiently and sufficiently remove the water droplets attached to the surface F to be dried by the pressurized air in the fourth step.
In addition, said "the minimum value of the flow velocity which can remove the water droplet adhering to the to-be-dried surface F" is the use environment {temperature, relative humidity, the state of the to-be-dried surface F of a user (user group) (thickness of body hair, The length of body hair, the density of body hair, the amount of sebum secretion, the amount of sweat secretion, the body temperature) etc.}, water droplets adhering to the surface to be dried evaporate from the surface to be dried F and move on the surface to be dried. Alternatively, it can be experimentally determined in advance by measuring the flow rate of the pressurized air when leaving (falling) from the surface F to be dried.

  Here, in the sanitary washing apparatus 100, the nozzle in the fourth step is used from the viewpoint of more efficiently and sufficiently removing water droplets attached to the surface F to be dried by the pressurized air. The flow rate of the pressurized air that is injected from the air outlet 21 of the unit 20 toward the surface to be dried (the flow rate when reaching the surface to be dried F) is preferably 20 to 100 m / S in the vicinity of the surface to be dried F. It is adjusted to. In addition, the suitable numerical range of the flow velocity of this pressurized air was calculated | required by experiment which the present inventors mention later.

  In this way, by setting the flow rate of the pressurized air in the fourth step to 100 m / s or less in the vicinity of the surface to be dried F, the pressurized air hits the surface to be dried F during the drying process in the fourth step. It becomes possible to more reliably prevent the user from feeling discomfort such as pain and cold.

  Further, by setting the flow rate of the pressurized air in the fourth step to 20 m / s or more in the vicinity of the surface to be dried F, the feeling of use given to the user when the pressurized air hits the surface to be dried F is more reliably comfortable. It is possible to move water droplets adhering to the surface to be dried F more smoothly and reliably from the outer edge portion of the surface to be dried F to the center of the surface to be dried F.

  Here, the lower limit value of the flow velocity is more preferably 30 m / S or more. Further, the upper limit value of the flow velocity is more preferably 50 m / S or less.

  Further, from the same point of view, the contact range of the jet of pressurized air that hits the surface to be dried F (excluding the range in which the pressurized air contacts the surface to be dried F after changing its direction) is, for example, the diameter The size is preferably set to about 1 cm.

  Hereinafter, the control operation of the control unit 150 in the fourth step will be described separately from the first step to the fifth step.

(3D-1) First Step In the period from T9 to T10 shown in FIG. 7, the control unit 150 performs the operation direction and operation of at least one of the rotation drive motor 54 and the advance / retreat drive motor 53 of the drive unit 52. By controlling the speed, the position of the nozzle unit 20 is moved as shown in FIG.

  In other words, the control unit 150 reciprocates the nozzle unit 20 at a high speed within a predetermined range (for example, a range from the position 50 mm ahead of the storage position to the position 150 mm), and simultaneously sets the rotation angle of the nozzle unit 20 to the right. It is slowly rotated from an angle at the right end of the turn (for example, + 50 °) to a predetermined angle (for example, + 20 °).

  By the control operation of the first step, the air jet from the air outlet 21 of the nozzle portion 20 is moved forward and backward from the predetermined position on the right side of the surface to be dried F as shown in the operation pattern P100 shown in FIG. It is gradually moved closer to the center G while being moved at a high speed.

  More specifically, as shown in the operation pattern P100 shown in FIG. 12, the contact range E of the human body's buttocks R (see FIG. 9) of the air jet from the air outlet 21 of the nozzle portion 20 to the surface to be dried F is The zigzag movement trajectory is drawn while gradually moving toward the center G while performing periodic movement that reciprocates at high speed in the tangential direction of the right end of the surface F to be dried.

  As a result, as shown in FIG. 10, since the injection of the pressurized air is started from the outside sufficiently outside the range of the cleaning water, the water droplets spreading and adhering to the right side of the surface F to be dried are moved to the central portion P (FIG. 10). 12 can be blown away while gathering in the direction of the central part G).

  Next, at the timing of T10 shown in FIG. 7, the control unit 150 temporarily stops the air pump 51, and rotates the rotation angle of the nozzle unit 20 to the angle (for example, −50 °) that becomes the left end of the left turn. . Further, at the timing of T10, the operation of the air pump 51 is restarted and injection of pressurized air is started.

(3D-2) Second Step In the period from T11 to T12 shown in FIG. 7, the control unit 150 operates and operates in at least one of the rotation drive motor 54 and the advance / retreat drive motor 53 of the drive unit 52. By controlling the speed, the position of the nozzle unit 20 is moved as shown in FIG.

  That is, the control unit 150 reciprocates the nozzle unit 20 at a high speed within a predetermined range (for example, a range between the position 50 mm ahead of the storage position and the position 150 mm), and simultaneously rotates the rotation angle of the nozzle unit 20 counterclockwise. It is slowly rotated from an angle at the left end of the rotation (for example, −50 °) to a predetermined angle (for example, −20 °).

  Due to the control operation of the second step, the air jet from the air outlet 21 of the nozzle portion 20 is moved forward and backward from a predetermined distance on the left side of the surface to be dried F as shown in the operation pattern P200 shown in FIG. It is gradually moved closer to the center G while being moved at a high speed.

  More specifically, as shown in the operation pattern P200 shown in FIG. 12, the contact range E of the human body's buttocks R (see FIG. 9) with the surface to be dried F is the tangential direction of the left end of the surface to be dried F. In this way, while being moved periodically at a high speed, it is gradually moved toward the center portion G, and a zigzag movement locus is drawn.

  As a result, as shown in FIG. 11, since the injection of the pressurized air is started from the outside sufficiently outside the range of the cleaning water, the water droplets spreading and adhering to the left side of the surface to be dried F are moved to the central portion P (FIG. 12 can be blown away while gathering in the direction of the central part G).

At the end time of this second step (time T12 shown in FIG. 7), the nozzle portion 20 is moved to the most advanced position (in FIG. 12, the nozzle portion 20 is projected most outward in the X-axis direction). Advance to position).

  After completing the control operations of the first step and the second step described above, the water droplets remaining on the surface F to be cleaned remain in the front-rear direction around the central portion G in FIG. Only water droplets remaining in the X-axis direction).

(3D-3) Third Step In the period from T12 to T13 shown in FIG. 7, the control unit 150 operates and operates in at least one of the rotation drive motor 54 and the advance / retreat drive motor 53 of the drive unit 52. By controlling the speed, the position of the nozzle unit 20 is moved as shown in FIG. That is, while the nozzle part 20 is slowly retracted in the direction of the center part G from the most advanced position (the position when the nozzle part 20 is projected most outward in the X-axis direction in FIG. 12), at the same time, the nozzle part 20 Is rotated at a high speed from the angle at the right end of the right turn to the angle at the left end of the left turn at a high speed.

  By the operation of the third step, as shown in the operation pattern P300 shown in FIG. 13, the air jet from the air outlet 21 of the nozzle portion 20 moves on the surface to be dried F at high speed in the left-right direction. It is made to approach the center part G gradually from the predetermined position of the front toward the rear.

  More specifically, as shown in the operation pattern P300 shown in FIG. 13, the contact range E of the human body's buttocks R (see FIG. 9) of the air jet from the air outlet 21 of the nozzle portion 20 to the surface to be dried F is The zigzag movement trajectory is drawn while gradually moving toward the center G while being periodically moved so as to reciprocate at high speed in the tangential direction on the tip side of the surface F to be dried.

  As a result, as shown in FIG. 13, water droplets remaining in front of the center portion G of the surface to be dried F can be blown off while being collected in the direction of the center portion G.

  Next, at the timing of T13 illustrated in FIG. 7, the control unit 150 temporarily stops the air pump 51 and sets the position of the nozzle unit 20 in the forward / backward direction (X-axis direction) to a predetermined position ( For example, it is moved to a position 50 mm ahead of the storage position. Further, at the timing of T13, the operation of the air pump 51 is restarted and injection of pressurized air is started.

(3D-4) Fourth Step In the period from T14 to T15 shown in FIG. 7, the control unit 150 performs the operation direction and operation of at least one of the rotation drive motor 54 and the advance / retreat drive motor 53 of the drive unit 52. By controlling the speed, the position of the nozzle unit 20 is moved as shown in FIG.

  That is, the control unit 150 slowly advances the nozzle unit 20 from a predetermined position behind the center unit G in the center unit G direction, and simultaneously rotates the nozzle unit 20 counterclockwise from the angle at the right end of the right turn. Drive back and forth at high speed up to the left end of the turn.

  By the operation of the fourth step, as shown in the operation pattern P400 shown in FIG. 13, the air jet from the air outlet 21 of the nozzle portion 20 moves at high speed in the left-right direction on the surface to be dried F of the user. It is gradually moved closer to the center part from a predetermined distance to the front while being moved.

More specifically, as shown in the operation pattern P400 shown in FIG.
Is gradually moved toward the center G while being periodically moved so as to reciprocate at a high speed in the tangential direction of the rear end of the surface to be dried F, and a zigzag movement locus is drawn.

  As a result, as shown in FIG. 13, water droplets remaining behind the central portion G of the surface to be dried F can be blown off while being collected in the central portion G direction.

  After completing the control operation from the first step to the fourth step described above, the water droplets remaining on the surface to be dried F are only the water droplets remaining in the vicinity of the central portion G in FIG. .

  Here, the control operation from the first step to the fourth step will be described in more detail.

  When the air ejection port 21 of the nozzle unit 20 moves by the control operation from the first step to the fourth step, the human body's buttocks R (see FIG. 9) of the air jet from the air ejection port 21 of the nozzle unit 20 Regarding the movement of the contact range E (see FIGS. 12 and 13) to the surface F to be dried, the moving speed in the direction in which the contact range E approaches the central portion G (hereinafter referred to as “approach direction”). The moving speed of the reciprocating motion in the direction crossing the approaching direction (hereinafter referred to as “crossing direction”) is sufficiently high.

  The “crossing direction” described above corresponds to the “tangential direction” of the surface to be dried F in the description of the control operation from the first step to the fourth step described above.

  For example, in the first step and the second step, with respect to the movement of the contact range E of the air jet from the air outlet 21 to the surface F to be dried, the contact range E approaches the center portion G. The crossing direction (direction substantially parallel to the X-axis direction shown in FIG. 12) intersecting the approach direction rather than the moving speed in the approaching direction (direction substantially parallel to the Y-axis direction shown in FIG. 12). The reciprocating movement speed is sufficiently high.

  Further, for example, in the third step and the fourth step, with respect to the movement of the contact range E of the air jet from the air outlet 21 to the surface to be dried F, the contact range E approaches the central portion G. Therefore, the crossing direction (direction substantially parallel to the Y-axis direction shown in FIG. 13) intersects the approach direction rather than the moving speed in the approaching direction (direction substantially parallel to the X-axis direction shown in FIG. 13). ) The reciprocating movement speed in (1) is sufficiently high.

  As a result, the flow of pressurized air that collides with the surface to be dried F and spreads increases in the component of the flow that spreads in the approaching direction relative to the component of the flow that spreads in the crossing direction.

  Accordingly, on the surface to be dried F, water droplets adhering between the contact range E of the air jet reciprocating in the intersecting direction and the center portion G are pushed closer to the center portion than the intersecting direction, and the center portion It moves in the direction of G.

  Thus, the water droplets adhering to the surface to be dried F are collected in the vicinity of the central portion G by the control operation from the first step to the fourth step.

  That is, the process by the control operation from the first step to the fourth step is a process of collecting water droplets attached to the surface to be dried F at the central portion G of the surface to be dried F.

  Next, at the timing of T15 shown in FIG. 7, the control unit 150 stops the air pump 51 again, and sets the position of the nozzle unit 20 in the forward / backward direction (X-axis direction shown in FIG. 13) to a predetermined position in front (for example, To the position 130 mm in front of the storage position).

  Then, at the timing of T <b> 16 illustrated in FIG. 7, the control unit 150 restarts the operation of the air pump 51 and starts the injection of pressurized air from the air outlet 21 of the nozzle unit 20.

(3D-5) Fifth Step During the period from T16 to T17 shown in FIG. 7, the control unit 150 performs the operation direction and operation of at least one of the rotation drive motor 54 and the advance / retreat drive motor 53 of the drive unit 52. The speed is controlled to start an advancing / retreating drive operation in which the nozzle portion 20 is moved backward along the X axis shown in FIG. 13 from a predetermined position in front.

  Then, the control unit 150 slowly retracts until the nozzle unit 20 passes under the center part P and is located at a predetermined position behind the center part P (for example, a position 50 mm ahead of the storage position). Further, at this time, the control unit 150 drives the nozzle unit 20 to reciprocate at a high speed from the angle at the right end of the right turn to the angle at the left end of the left turn simultaneously with the above-described operation.

  By the control operation in the fifth step, the air jet from the air jet port 21 of the nozzle portion 20 moves at high speed in the left-right direction (Y-axis direction shown in FIG. 13) on the surface to be dried F of the user. While being cyclically moved, it is gradually moved backward from a predetermined position in the front to approach the center G, and further moved to a predetermined position after passing through the center G.

  Thus, the contact range E of the human body's buttocks R (see FIG. 9) with the surface to be dried F of the air jet from the air outlet 21 of the nozzle portion 20 is along the X-axis direction shown in FIG. It gradually moves from the front through the center G to the rear. As a result, water droplets remaining in the central portion G of the surface to be dried F can be completely blown away.

  That is, the process by the control operation of the fifth step is a process of blowing water droplets collected at the central portion G of the surface F to be dried by the control operation of the first step to the fourth step.

  Next, at the timing of T17 shown in FIG. 7, the control unit 150 stops the air pump 51 and moves the position of the nozzle unit 20 to the storage position at the rear end. In addition, the control unit 150 sets the rotation angle of the nozzle unit 20 to the standby position (standby angle) at the time of standby described above between the time points when the nozzle unit 20 is positioned at the storage position or after the nozzle unit 20 is positioned at the storage position. Complete the return control.

  With the above, the process using the nozzle unit 20 in the drying process is completed.

  Next, when the user depresses the stop switch 311 of the remote control device 300, the control unit 150 stops the operation of the heater 44 (timing T18 shown in FIG. 7).

  Next, the control unit 150 stops the air fan 41 (timing T19 shown in FIG. 7).

  Next, the remaining heat of the heater 44 is reduced, and the entire drying process is completed.

  In addition, the ejection range of the pressurized air in the fourth step is an ejection range set in advance according to bidet cleaning when the immediately preceding cleaning treatment step is bidet cleaning.

For example, when the position of cleaning by the nozzle unit 20 is adjusted, for example, from the position of 100 mm forward from the storage position of the nozzle unit 20 to 110 mm forward in the middle of the immediately preceding cleaning process step, the nozzle unit 20 accordingly The to-be-dried surface F is in a wide area range from 50 mm forward from the storage position to 160 mm forward from the storage position.

  In addition, in the cleaning process, when the butt cleaning and the bidet cleaning are each performed once or more, in the subsequent drying process, the surface to be dried F set for the butt cleaning is set for the bidet cleaning. Two of the surfaces to be dried F are combined to form one surface to be dried F, and an ejection range of pressurized air corresponding to this is set.

  In this case, for example, the pressurized air ejection range is a range from 50 mm in front of the storage position to 180 mm in front of the storage position.

  Further, in this case, the movement trajectory of the contact range E of the air jet flow from the air outlet 21 of the nozzle portion 20 to the surface to be dried F in the operation control from the first step to the fifth step is as follows. It is preferable that the pattern shape of P100, P200, P300, and P400 shown in FIGS. 12 and 13 is not changed by merely enlarging the dry surface F in a similar manner.

  Thereby, the movement trajectory of the contact range E of the air jet on the surface F to be dried does not overlap the overlapping range on the surface F to be dried corresponding to the buttocks cleaning and the surface F to be dried corresponding to the bidet cleaning. can do. Therefore, even if the butt cleaning and the bidet cleaning are each performed once or more, the drying process can be efficiently performed in a short time.

  As described above, in the present embodiment, a configuration is employed in which the cleaning process (wet cleaning and bidet cleaning) and the drying process can be performed with one nozzle unit 20.

  Therefore, it is possible to employ a configuration in which a drive unit for driving the nozzle unit 20 for the cleaning process and a drive unit for driving the nozzle unit 20 for the drying process are shared. Therefore, according to the present embodiment, the installation space of the nozzle unit 20 can be easily reduced sufficiently, and the number of components can be easily reduced, so that space saving and cost reduction are easy. Can be realized.

  Moreover, in this embodiment, it is comprised so that the pressurized air for a drying process process may be injected from the one air jet nozzle 21. FIG.

  Thereby, even if the flow volume of the pressurized air supplied to the nozzle part 20 is low, the flow velocity of the air jet injected from the air jet port 21 can be easily increased. Therefore, even when a relatively small capacity and small output air pump is employed, good drying performance can be easily obtained.

  In addition, since it is possible to easily increase the flow velocity of the jet of pressurized air, it is easy to ensure sufficient force (energy) when the jet contacts the water droplets attached to the surface F to be dried and peels off the water droplets. To be able to.

  Therefore, according to the present embodiment, it is easy to reliably obtain a flow velocity that is equal to or higher than the minimum value at which water droplets attached to the surface to be dried F can be removed, and water droplets can be efficiently blown away.

  Furthermore, in this embodiment, by adjusting the output of the air pump to be low, it is possible to easily adjust the flow rate to be lower than the minimum value of the flow rate at which water droplets attached to the surface F to be dried can be removed.

Thus, according to the present embodiment, the flow rate of the pressurized air in the second step is set to a sufficiently small optimum range (preferably 5 m / s or more per second and preferably 20 m per second) in the vicinity of the surface F to be dried. Less than / s).

  In addition, the above-mentioned optimum range is that the dry air is being applied to the central portion of the surface to be dried including the user's local area, and the user adheres to the surface to be dried more reliably while recognizing it more reliably. This is a range in which water droplets can be more reliably prevented from spreading from the center of the surface to be dried.

(Second Embodiment)
The sanitary washing device 100A (not shown) of the second embodiment includes the entire unit including the nozzle unit 20, the drive unit 52, and the support unit 80 in the sanitary washing device 100 of the first embodiment shown in FIG. In addition, a swing drive unit (not shown) for swinging driving is further provided.

  The sanitary washing device 100A according to the second embodiment mainly includes the above-described swing drive unit, and the control unit 150 controls the operation of the swing drive unit. It has the same configuration as the sanitary washing device 100 of one embodiment.

  Therefore, in the following description, the same code | symbol is attached | subjected to the same or equivalent part as the sanitary washing apparatus 100 of 1st Embodiment, and the overlapping description is abbreviate | omitted.

  The swing drive unit is fixed to the annular toilet seat 400 (toilet seat) having the seating surface F400 on which the user is seated as shown in FIG. 1 and the support unit 80, and the tip of the nozzle unit 20 is controlled by the control unit 150. This is for swinging and driving in the lateral direction intersecting the axial direction of the nozzle portion 20 (the direction of the axis indicated by the dotted line AB in FIG. 5) in a plane substantially parallel to the seating surface F400.

  The support unit 80 is connected to the swing drive unit so as to instruct the swing drive unit to swing in the lateral direction.

  More specifically, the swing drive unit is coupled to one of the bottom surfaces of the main body 55 (structure having a substantially triangular prism shape) of the support unit 80 shown in FIG. Further, the swing drive unit is coupled to the main body 55 so that the swing shaft (rotating shaft) that enables the swing in the lateral direction is substantially parallel to the Z axis shown in FIG. The As a result, the entire unit including the nozzle unit 20, the drive unit 52, and the support unit 80 can be driven to swing.

  The sanitary washing device 100A according to the second embodiment includes the swing drive unit, so that the relative position of the washing water outlet 22 of the nozzle unit 20 with respect to the surface to be cleaned in the cleaning process and the target in the drying process. The relative position of the air outlet 21 of the nozzle portion 20 with respect to the drying surface F can be adjusted more precisely, and water droplets adhering to the surface to be dried F can be removed more easily and more reliably.

(Modification)
The sanitary washing device 100 according to the first embodiment and the sanitary washing device 100A according to the second embodiment have been described above. However, the sanitary washing device according to the present invention includes the sanitary washing device 100 according to the first embodiment and the second embodiment. It is not limited to the sanitary washing device 100A of the second embodiment.

  For example, in the sanitary washing device 100 of the first embodiment, as the nozzle unit 20, a washing water jet port 22 that jets cleaning water and an air jet port 21 that jets pressurized air are combined into one nozzle. The case where the structure which has is demonstrated was demonstrated.

  However, the sanitary washing device of the present invention is not limited to this configuration.

  For example, the nozzle part in the sanitary washing device of the present invention may employ a configuration in which a cleaning nozzle having the cleaning water jet port 22 and a drying nozzle having the air jet port 21 are provided separately. Good. Further, a configuration may be adopted in which the nozzle for washing the butt and the nozzle for cleaning the bidet are made independent nozzle parts, and drive parts for driving the nozzle parts are also provided independently.

  In this case, the cleaning nozzle and the air jet 21 may be configured to be able to advance / retreat, rotate, and swing independently of each other. In the cleaning process, only cleaning water is ejected, and the drying process is performed. The configuration may be such that only the pressurized air is ejected, and the cleaning nozzle and the air ejection port 21 are interlocked with each other during forward / backward drive, rotational drive, and swing drive.

  In addition, when the nozzle unit 20 includes a cleaning water jet port 22 that jets cleaning water to one nozzle and an air jet port 21 that jets pressurized air, the cleaning water jet port 22 and the air jet port 21 The installation position is not particularly limited as long as the effects of the present invention can be obtained. For example, the installation position of the washing water ejection port 22 and the installation position of the air ejection port 21 shown in FIG. 5 may be reversed.

  Furthermore, the sanitary washing apparatus 100 of 1st Embodiment demonstrated the structure in case the number of the air jet nozzles 21 of the nozzle part 20 is one. However, the sanitary washing device of the present invention may have a configuration in which a plurality of air jets 21 are provided in one nozzle portion 20 to inject pressurized air.

  Moreover, the structure which arrange | positions the several nozzle part 20 which has the air jet nozzle 21, and the several drive part for driving this may be sufficient. By injecting a plurality of air jets of pressurized air, the drying time of the surface to be dried F can be shortened.

  Furthermore, in the sanitary washing device 100 of the present invention, in the sanitary washing device 100 of the first embodiment, only the pressurized air supply unit 50 is driven and only the pressurized air is injected from the nozzle unit 20 onto the surface to be dried F. You may be comprised so that 3 drying operation modes can be performed.

  As a result, the drying process is performed without operating the hot air supply unit 40, so that power consumption can be reduced. This third drying operation mode is effective when it is executed when the temperature in the toilet room is relatively high, such as in summer.

  Moreover, in the sanitary washing apparatus 100 of 1st Embodiment, although the case where it was preferable that the flow rate of the pressurized air in the 4th process of a drying process is 20 m / s-50 m / s was demonstrated, The sanitary washing device is limited to the sanitary washing device 100 of the first embodiment described above as long as the flow rate of the pressurized air in the fourth step is higher than the flow rate of the pressurized air in the second step in the drying process. Is not to be done.

  For example, the flow velocity in the fourth step is the diameter of the air outlet 21 of the nozzle portion 20 and the number of air outlets 21 which are setting elements for the size of the contact range E between the surface to be cleaned F and the jet of pressurized air. , The capacity of the air pump, the flow rate of the pressurized air supplied into the nozzle unit 20, the distance between the surface to be cleaned F and the air jet 21, the allowable time of the drying process, the temperature of the atmosphere in which the drying process is performed, and the drying What is necessary is just to set in consideration of the humidity etc. of the atmosphere which implements a process process. For example, the flow rate in the fourth step may be 20 m / s to 200 m / s.

  Moreover, in the sanitary washing apparatus 100 of 1st Embodiment, although the case where the structure which drives the nozzle part 20 whole with the drive part 52 was employ | adopted was demonstrated, the sanitary washing apparatus of this invention is not limited to this. .

  For example, the sanitary washing device of the present invention jets a jet of pressurized air in the drying process by driving only the air outlet of the nozzle part or only the peripheral members including the air outlet forward or backward. You may employ | adopt the structure which moves the contact range E of the to-be-cleaned surface F and the jet of pressurized air within the area | region of the to-be-cleaned surface F by changing a direction.

  Moreover, the sanitary washing apparatus of this invention may employ | adopt the structure which provides the wind direction change means which changes the direction of the jet flow of pressurized air ahead of the air jet nozzle of a nozzle part.

  Moreover, in the sanitary washing apparatus 100 of 1st Embodiment, the case where the case where the case where the 1st to 5th step is performed sequentially is employ | adopted is demonstrated about the control operation of the control part 150 in the 4th process of a drying process. However, the sanitary washing device of the present invention is not limited to this.

  For example, the sanitary washing apparatus of the present invention can be configured to repeatedly and independently execute each step from the first step to the fifth step according to the user's request, the state of removal of water droplets attached to the surface to be dried, etc. It is good.

  For example, the sanitary washing device of the present invention may change the order of each step from the first step to the fifth step.

  Furthermore, for example, the sanitary washing device of the present invention may omit the first step and the second step. For example, the sanitary washing device of the present invention may omit the third step and the fourth step.

  Furthermore, in the sanitary washing device 100 according to the first embodiment, the case where the heater is energized before starting the air fan at the start of the drying process to speed up the temperature rise of the heater has been described. The sanitary washing device is not limited to this.

  For example, the sanitary washing device of the present invention has a soft start function that simultaneously activates the air fan and the heater at the start of the drying process and then gradually increases the air flow rate when the air fan is activated. You may speed up the climb.

  Further, the sanitary washing apparatus of the present invention is configured to move the pressurized air ejection range on the surface to be dried in the subsequent drying process step, centering on the setting value of the position adjustment of the cleaning water on the surface to be cleaned in the cleaning process step It is good. Thus, by centering on the actual cleaning position, the water droplet removal effect by the pressurized air can be stably maintained high even if the cleaning position changes.

  Furthermore, the area of the cleaning range on the surface to be cleaned in the cleaning process varies depending on the position of the cleaning move and the cleaning water. Therefore, the sanitary washing apparatus of the present invention may be configured to change the area of the pressurized air ejection range on the surface to be dried in the subsequent drying process so as to be proportional to the area of the cleaning range on the surface to be cleaned. In this way, when the narrow area of the surface to be cleaned is wet, the pressure is applied to the narrow area corresponding to the narrow area.When the wide area to be cleaned is wet, the pressure is applied to the wide area corresponding thereto. By ejecting air, water droplets can be efficiently removed in a short time.

  In the sanitary washing device of the present invention, the area of the compressed air ejection range on the surface to be dried in the drying process may be arbitrarily selected from a plurality of preset values.

This is to allow the user to select a suitable compressed air ejection range, for example, to select from five preset areas from “wide” to “narrow”. is there. As a result, the user can empirically judge from the water droplet removal state around his / her own area and select the jetting range of the pressurized air, whereby efficient water droplet removal according to individual differences and cleaning conditions can be performed.

  Further, in the sanitary washing apparatus of the present invention, the following “cleaning move” operation control of “wet washing” may be performed in the washing process.

  Hereinafter, the case where the control operation of the “cleaning move” operation of “wet cleaning” is performed in the cleaning process of the sanitary cleaning device 100 of the first embodiment will be described with reference to FIG.

  The operation from time T0 to T3 shown in FIG. 8 is the same as that 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. In accordance with this operation, the advance / retreat drive motor 53 is driven to advance the nozzle unit 20 by a predetermined amount (for example, a position 3 mm forward from the storage position), 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. In accordance with this operation, the rotation drive motor 54 is driven to rotate the nozzle portion 20 in the direction of left turn by a predetermined amount (for example, a rotation angle of 3 ° in the direction of left turn), thereby moving and adjusting the cleaning position.

  In this way, each time the position adjustment switch is pressed, the nozzle unit is driven by a predetermined amount, whereby 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 the operation speed of the rotation drive motor 54 and the advance / retreat drive motor 53 of the drive unit 52 are controlled, and the advance / retreat drive of the nozzle unit 20 is performed at a predetermined distance (for example, 8 mm in the advance / retreat direction from the set position). The reciprocating operation is performed at a medium speed (for example, 1 Hz), and at the same time, the rotation angle of the nozzle unit 20 is reciprocated at a predetermined angle (for example, a set rotation angle ± 3 °) at a high speed (for example, 5 Hz). Accordingly, the cleaning 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 “narrow” is that the set value of the reciprocating rotation angle of the left turn and the right turn of the nozzle unit 20 is widened. For example, the cleaning range can be widened by setting the rotation angle of the left turn and the right turn to the set rotation angle ± 5 °.

  At time T26 and time T27, the user depresses the “wide” switch 330 (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 “middle” is that the set value of the reciprocating rotation angle of the left turn and the right turn of the nozzle unit 20 is further widened. For example, the reciprocating rotation angle of the left turn and the right turn can be set to ± 7 ° to further widen the cleaning range.

  At the time T28 when the butt washing is finished and the user depresses the stop switch 311 of the remote control device 300, the same end operation as described in FIG. 7 is performed. The set value adjusted for the cleaning position is stored until this end operation, and even if the cleaning move operation is performed halfway, the set value is returned to the set position when the cleaning move operation is completed.

Hereinafter, although the content of the sanitary washing apparatus of the present invention will be described in more detail with reference to Examples and Comparative Examples, the present invention is not limited to these Examples.

The conditions were the same as those in Evaluation Test 1 except that the center G was the geometric center of the flocking range of the pseudo hair (42 mm × 42 mm).

When performing the process of a 4th process, it replaced with the to-be-dried surface F of the human body's buttocks R, used the said to-be-dried surface F (pseudo to-be-dried surface F), and the center part G made the flocking range of the artificial body hair. Evaluation test except that the geometric center of (42 mm x 42 mm) was set, and the area to which the pressurized air was applied in the fourth step was set to a range of 50 mm x 50 mm including the flocked hair transplantation range (42 mm x 42 mm). 1 and the same conditions.
2. Subject One test plate having the above-described surface to be dried F (pseudo surface to be dried F) was used.
3. Test procedure (Examples 1 to 6) and (Comparative Examples 1 to 6)
First, for each of the to-be-dried surfaces F (pseudo to-be-dried surfaces F) of Examples 1 to 6 and Comparative Examples 1 to 6, the number of drying treatment steps in each condition of the dry air flow rate shown in Table 1 below is shown. A two-step process was performed.

  Hereinafter, the process of a 2nd process is demonstrated using FIG.14 and FIG.15.

  FIG. 14 is a schematic diagram illustrating a state of the surface to be cleaned F before the second step is performed. FIG. 15 is a schematic diagram showing the state of the surface to be cleaned F after the second step is performed.

  First, as shown in FIG. 14, the second process is performed on the surface to be dried F to which the water droplets WD are attached until the entire surface to be cleaned F is saturated.

  Next, pressurized air was applied for 10 seconds at each flow rate shown in Table 1 below from the air outlet 21 of the nozzle unit 20 toward the center G of the surface F to be dried. At this time, it was set in advance so that the jet of pressurized air hits the surface to be dried F around the central portion G.

  Next, as shown in FIG. 15, the area (the surrounding area centered on the central portion G) from which the water droplets WD are removed in the surface to be dried F after the second step is centered on the central portion G. And a radius r of the circle F1 {circular contact with the water droplet WD (the water droplet WD having a diameter of 0.5 mm or more) whose circumference is closest to the center portion G}}. Was measured.

  Next, the fourth step under the conditions shown in Table 1 for each dried surface F (pseudo dried surface F) of Examples 1 to 6 and Comparative Examples 1 to 6 in the state after the above measurement. This process was performed for 5 minutes, and the degree of progress of drying in a range of 50 mm × 50 mm including the flocked range (42 mm × 42 mm) of each surface to be dried F was compared.

  The standard for comparison was as follows.

  “Done”: Water droplets are collected in the central portion G and the drying process is completed within 5 minutes (water droplets remaining on the surface to be dried F after the fourth step with respect to the surface F to be dried before the fourth step) Of 0.1 g or less).

“Incomplete”: Water droplets are collected in the central portion G, and the drying process is incomplete within 5 minutes (remains on the surface to be dried F after the fourth process relative to the surface F to be dried before the fourth process). The mass of water droplets to be exceeded exceeds 0.1 g).
4). Test results The results of the above evaluation test 2 are shown in Table 1.

As is clear from the results shown in Table 1, it is confirmed that Examples 1 to 6 according to the present invention can sufficiently prevent the occurrence of erroneous user recognition in the second step as compared with Comparative Examples 1 to 6. It was done. Further, in Examples 1 to 6 according to the present invention, in the fourth step, even when water droplets diffuse from the central portion G toward the periphery by the processing of the second step, the surface to be dried F is kept for a predetermined time.

(5) Pressurized air ejection conditions The conditions were the same as those in Evaluation Test 1.
2. Subject The same conditions as in Evaluation Test 1 were used.
3. Test procedure (Reference Examples 8 to 11)
First, the surfaces to be dried F of Reference Examples 8 to 11 to which water droplets were attached under the same conditions as in the evaluation test 1 were prepared. That is, using a spray, water droplets were applied to the surface to be dried F until the water droplets adhered to the entire surface to be dried F became saturated (steady state).

Next, with respect to each surface to be dried F of Reference Examples 8 to 11, under the conditions shown in Table 3, the subject was given central air (near the anus) for 1 second by applying pressurized air to the center G (anus). We investigated whether or not we felt that a jet of pressurized air was hit in the vicinity), and determined the proportion of subjects who felt that a jet of pressurized air was hit.
4). Test results Table 3 shows the results of the evaluation test 4 described above.

  As is clear from the results shown in Table 3, in comparison with Reference Examples 8 to 9, Reference Examples 10 to 11 in which the flow rate of the pressurized air in the second step was 5 m / s or more were shifted to the position of starting drying. It was confirmed that the occurrence of misrecognition that there is a problem can be prevented more reliably.

  The sanitary washing device of the present invention is more reliable while sufficiently reducing the discomfort of the user when the surface to be cleaned is washed with cleaning water and then the surface to be dried wet with the cleaning water is dried with pressurized air. It is possible to remove water droplets. Moreover, it is possible to prevent the water droplets of the cleaning water adhering to the surface to be dried from spreading more than necessary in the drying process.

  Therefore, the sanitary washing device of the present invention can be suitably applied to the fields and uses of the human sanitary washing device.
