Description

  The present invention relates to a sanitary washing device for washing a local body part.

  More particularly, the present invention relates to a sanitary washing apparatus having a drying function of removing water droplets on the surface of a human body portion that has been wetted by air jets and drying the surface.

  In the field of a sanitary washing apparatus that is installed on the upper surface of a toilet bowl and cleans a local part of a human body, various functions have been proposed in order to realize washing according to the user's preference. For example, after performing local cleaning using a sanitary cleaning device, instead of the user removing water droplets attached to the local area with paper such as toilet paper, a nozzle having a spout that ejects pressurized air at the tip is provided. There has been proposed a sanitary toilet seat device having a drying device that dries pressurized local air by spraying it locally.

  As a sanitary toilet seat apparatus having such a drying apparatus, for example, the compressed air is jetted to the tip part in order to efficiently dry the local part in a short time without causing discomfort to the user.

  However, even the conventional sanitary washing device described in Patent Document 1 still has room for improvement from the viewpoint of achieving compactness and obtaining sufficient reliability.

  That is, as described above, in the sanitary washing device described in Patent Document 1, the rotation driving means (swinging means) is fixed to the rear end portion of the nozzle, and the advance / retreat drive is performed together with the nozzle by the operation of the advance / retreat driving means. It is supposed to be configured. For this reason, since the rotation drive means is driven back and forth with the advance and retreat drive of the nozzle, it is necessary to secure a movement space for moving the rotation drive means such as a motor and a movement space for wiring connected to the rotation drive means. was there.

  Therefore, the sanitary washing device described in Patent Document 1 still has room for improvement from the viewpoint of downsizing the entire device, which is important when installed in a limited installation space such as on a toilet bowl.

  Further, in the sanitary washing apparatus described in Patent Document 1, since the wiring connected to the rotation driving means is moved together with the advance and retreat drive of the nozzle, the viewpoint of obtaining sufficient reliability of the apparatus when long-term use is assumed. There was still room for improvement.

  The present invention has been made in view of the above-mentioned problems of the prior art, and is a compact and highly reliable sanitary washing apparatus even when the nozzle advancing / retreating driving means and the rotation driving means are combined. The purpose is to provide.

In order to solve the above-described problems of the prior art, the present invention provides:
A cylindrical nozzle having an air outlet at the tip part for ejecting pressurized air in the direction of the human body part;
A nozzle holder that is integrally connected to the rear end of the nozzle and supports the nozzle so as to be rotatable about its axis as a rotation center;
A support portion for supporting the nozzle and the nozzle holder so as to be capable of moving forward and backward in the direction of the axis of the nozzle;
Advancing / retreating drive means fixed to the support part, for advancing / retreating the nozzle and the nozzle holder in the axial direction of the nozzle;
A rotation means fixed to the support portion and configured to drive the nozzle to rotate about the axis;
At least,
The advance / retreat driving means is connected to the first electric motor fixed to the support portion, the first electric motor, and the nozzle holder, and performs rotational movement of the shaft of the first electric motor to the nozzle and First connecting means for converting the nozzle holder into advancing and retracting drive,
The rotating means is connected to the second electric motor fixed to the support portion, the second electric motor, and the nozzle, and rotates the shaft of the second electric motor to rotate the nozzle. Second connecting means for converting to drive ,
The second connecting means includes
Provided to be substantially parallel to the axis of the nozzle with respect to the nozzle; and
A shaft rotatably arranged with respect to the support part;
A first transmission means fixed to the support portion and transmitting the rotation of the second electric motor to the shaft;
It is fixed to the nozzle holder so as to interlock with the advance / retreat drive of the nozzle, and
A rotating body that is fitted to the shaft so as to be rotatable in conjunction with the rotation of the shaft and transmits the rotation to the nozzle ,
A sanitary washing device is provided (claim 1).

  As described above, the sanitary washing device of the present invention is such that the second electric motor of the rotating means is fixed to the support portion.

  Therefore, in the sanitary washing device of the present invention, the second electric motor is fixed to the support portion even when the nozzle is driven forward / backward by the operation of the nozzle forward / backward driving means. Therefore, in the sanitary washing apparatus of Patent Document 1 described above, it is not necessary to secure a movement space for moving the rotation driving means such as a motor and a movement space for wiring connected to the rotation driving means.

  Therefore, the sanitary washing device of the present invention can easily make the entire device compact which is important when installed in a limited installation space such as on a toilet bowl.

  Further, in the sanitary washing device of the present invention, since the wiring connected to the rotating means does not move together with the advance / retreat driving of the nozzle, sufficient reliability of the device can be easily obtained when long-term use is assumed.

  Therefore, according to the sanitary washing device of the present invention, it is possible to easily and reliably obtain a compact size and sufficient reliability of the device even when the nozzle advancing / retreating drive means and the turning means are both provided. become.

In addition, from the viewpoint of more reliably obtaining the above-described effects of the present invention, in the sanitary washing device of the present invention, the second connecting means is:
Provided to be substantially parallel to the axis of the nozzle with respect to the nozzle; and
A shaft rotatably arranged with respect to the support part;
A first transmission means fixed to the support portion and transmitting the rotation of the second electric motor to the shaft;
A rotating body that is fixed to the nozzle holder so as to be interlocked with the advance / retreat drive of the nozzle, and is rotatable to be interlocked with the rotation of the shaft, is fitted to the shaft, and transmits the rotation to the nozzle;
It is preferable to have .

  With this configuration, when the nozzle is driven to rotate by the operation of the rotating means, the rotation of the second electric motor is transmitted to the first transmitting means of the second connecting means in the rotating means. And transmitted from the first transmission means to the shaft of the second connecting means, transmitted from the shaft to the rotating body of the second connecting means, and transmitted from the rotating body to the nozzle to rotate the nozzle. Become.

  In addition, the second electric motor of the rotating means is fixed to the support portion, and the first transmission means and the shaft of the second connecting means of the rotating means are also fixed to the support portion. On the other hand, among the second connecting means of the rotating means, only the rotating body is configured to move in conjunction with the advance / retreat drive of the nozzle.

  Therefore, when the nozzle is driven forward / backward by the operation of the forward / backward drive means, only the rotating body moves in conjunction with the forward / backward drive of the nozzle. Therefore, it is not necessary to secure a moving space for the second electric motor that occupies a large volume in the rotating means and a moving space for wiring connected to the second electric motor.

  In this configuration, the rotating body of the rotating means moves in conjunction with the advance / retreat operation of the nozzle, but the movement space of the second electric motor itself moves in conjunction with the advance / retreat operation of the nozzle. Compared to the case, it can be easily made extremely small.

  The reason is the following three points. That is, firstly, the first transmission means such as a gear connected to the rotating shaft of the second electric motor is arranged in a relatively small space at the tip of the rotating shaft of the second electric motor. This is because the volume can be made relatively small. Secondly, the diameter of the shaft connected to the first transmission means can be easily set to a level substantially equal to the diameter of the rotating shaft of the second electric motor. Third, the rotating body fitted to the shaft (having a relatively small diameter) can be easily configured to have a small volume by forming a cylindrical shape or the like.

  Furthermore, the sanitary washing device of the present invention requires an inevitable space for providing a pipe for supplying pressurized air to the air outlet at the tip of the nozzle. Furthermore, in the case where a cleaning water outlet for ejecting cleaning water for cleaning the human body part is provided at the tip of the nozzle, an inevitable space for providing piping for supplying the cleaning water to the cleaning water outlet is also required. Become.

On the other hand, when the above configuration (Claim 1 ) is adopted, the shaft is disposed substantially parallel to the nozzle axis with respect to the nozzle. Therefore, it is possible to easily secure a sufficiently small installation space in which the above-described piping can be arranged in an orderly manner between the nozzle and the shaft (rotating means) (see FIG. 5 described later). And when installing the above-mentioned piping, about the part along a nozzle and a shaft of piping, the axis | shaft of piping can be arrange | positioned so that it may become substantially parallel with the axis | shaft of a nozzle and the axis | shaft of a shaft. In this way, even when the above-described pipe is driven forward / backward in conjunction with the advance / retreat drive of the nozzle, the portion of the pipe along the nozzle and the shaft is in the space formed between the nozzle / shaft. Since it is housed in an orderly manner, it is possible to easily reduce the moving space for driving the pipe forward and backward.

  Furthermore, in the case of this configuration, it is possible to sufficiently reduce the excessive mechanical stress (load) applied to the piping when the above-described piping is driven forward / backward in conjunction with the advance / retreat driving of the nozzle. Therefore, in the case of this configuration, it becomes easy to sufficiently ensure the life of the pipe, so that the reliability of the pipe can be obtained easily and reliably.

In the sanitary washing device of the present invention, when the above-described configuration (Claim 1 ) is adopted, the first transmission means has a configuration in which the second electric motor and the shaft are directly connected. The rotation of the second electric motor is preferably transmitted to the shaft (claim 2 ).

  In this case, the first transmission means can be formed as a structure for fitting a concave portion (or convex portion) or the like in the connecting portion with the shaft of the second electric motor, It can form as a structure for fitting, such as a convex part (or concave part), in a connecting part with 2 electric motors. This eliminates the need for parts for the first transmission means, so that it is possible to sufficiently reduce power transmission loss and power transmission failure of the second electric motor. In addition, manufacturing costs (reducing parts costs, reducing the occurrence of defective products by reducing assembly work, etc.) can also be achieved.

Further, from the viewpoint of obtaining the above-described effect of the present invention more reliably, in the sanitary washing device of the present invention, the first connecting means is a belt drive mechanism between the first electric motor and the nozzle holder. It is preferable to have the structure which connects by (claim 3 ).

Accordingly, it is possible to easily convert the rotational motion of the first electric motor into the forward / backward drive of the nozzle with a relatively simple configuration.

Furthermore, from the viewpoint of obtaining the above-described effect of the present invention more reliably, in the sanitary washing device of the present invention, the first connecting means is a sliding screw mechanism between the first electric motor and the nozzle holder. preferably it has a structure for connecting (claim 4).

  Thus, by connecting the first electric motor and the nozzle holder by the sliding screw mechanism, the advancing / retreating drive means can be arranged in a relatively narrow space, and the nozzle can be driven forward / backward more easily and reliably. Become.

  ADVANTAGE OF THE INVENTION According to this invention, even if it is a case where it has a nozzle advancing / retreating drive means and a rotation drive means together, it becomes possible to provide a sanitary washing device that is compact and excellent in reliability.

  The entrance detection sensor 700 is attached by selecting a place where a user's entrance and exit such as an entrance of a toilet room can be easily detected.

  The entrance detection sensor 700 is not particularly limited as long as it can detect the user entering the toilet room and leaving the toilet room. For example, a reflective infrared sensor can be employed. In this case, the room entry detection sensor 700 is configured to detect that a user has entered the toilet room when infrared rays reflected from the human body are detected.

The control unit 150 (see FIGS. 3 and 4) of the main body unit 200 controls operations described later of the sanitary washing device 100 based on signals transmitted from the remote operation device 300, the entrance detection sensor 700, and the seating sensor 610. Is.

  As shown in FIG. 1, the air ejection means 50 mainly includes an air pump 51 that supplies pressurized air, a cylindrical nozzle 20 that has an air ejection port 21 that ejects this pressurized air at the tip, and an air jet In order to move the jet of pressurized air ejected from the outlet 21 back and forth and to the left and right, an operation for driving the nozzle 20 forward and backward in its axial direction and an operation for driving the nozzle 20 to rotate about its axis are performed. It is comprised with the drive means 52. FIG. The drive means 52 has a configuration capable of executing the forward / backward drive and the rotational drive of the nozzle 20 simultaneously, and also has a configuration capable of executing the forward / backward drive and the rotational drive independently.

  The pressurized air ejected from the air ejecting means 50 has the ability of a wind speed of 20 to 50 m per second to reach the “dried surface” of the user's local area. The contact range of the jet on the “dried surface” is as follows: The diameter is set to about 1 cm.

  Further, the nozzle 20 is integrally configured with a cleaning nozzle portion 33 of a cleaning water jetting unit 30 including a cleaning water jet port 22 for jetting cleaning water.

Is for cleaning the “surface to be cleaned” of the bidet (user's local area) by spraying the bidet cleaning water.

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

  Moreover, it is preferable that the range of the “surface to be dried” in the present embodiment is a range that can be wetted with cleaning water when it is cleaned with cleaning water in and around the human body part. Furthermore, the range (area) of the “surface to be dried” is equal to or greater than the range (area) of the “surface to be cleaned”, and the “surface to be dried” is set to include the entire range of the surface to be cleaned. Is preferred. In addition, this “range that can be wetted with cleaning water” usually includes the above-mentioned “surface to be cleaned”, that is, “the range that can be contaminated by the excretion of the user in and around the human body part” If the “surface to be cleaned” does not include the “surface to be cleaned” range, the range of “surface to be dried” is the range of “surface to be wet with cleaning water” and “surface to be cleaned”. It is preferable that it is the range containing.

  The four tubes 39 include one having one end connected to the air inlet of the nozzle 20 and one connected to the cleaning water inlet of the nozzle 20. The other ends of the four tubes 39 are fixed to a fixing portion (not shown). The fixed portion has a configuration communicating with the air pump 51, and the switching valve 32 that switches the flow of the washing water (hot water) from the hot water heating means 31 between the direction of the nozzle 20 and the direction of the nozzle washing portion is also provided. It has the structure which communicates.

  As described above, in the case of the present embodiment, the four tubes 39 are connected at one end to the air inlet of the nozzle 20 or the cleaning water inlet of the nozzle 20. Is also configured to rotate (or move).

  Here, the rotation range (rotation angle range) of the nozzle 20 when the nozzle 20 rotates and jets pressurized air from the air outlet 21 is such that the pressurized air is applied to the surface to be dried of the user's local area. Pre-positioned so as to be in an appropriate range. The four tubes 39 are connected to the air inlet or the cleaning water inlet and the fixed portion so that the positioned state does not change with the course of use.

The side surface is erected so as to be in a state of being inclined forward (facing downward) from the rear to the front. The longitudinal direction of the side surface that is inclined forward (hereinafter, this side surface is referred to as “the upper surface of the support portion 55”) is configured to be substantially parallel to the axial direction of the nozzle 20.

  The bottom surface of the substantially right triangle of the support portion 55 is hereinafter referred to as “side surface of the support portion 55” in the present specification. Further, hereinafter, in this specification, “forward direction” indicates the A direction in FIG. 5, and “rear direction” indicates the B direction.

At this time, the direction of the axis of the nozzle 20 is a position suitable for a drying operation in which a tip portion where the air jet port 21 is formed is set in advance when performing a drying operation of drying a surface to be dried of a user's local area. It is set in a direction that can extend up to.

  More specifically, a nozzle holder 58 for supporting the nozzle 20 so as to be rotatable about its axis as a rotation center is disposed on the rear end portion of the nozzle 20 on the upper surface of the support portion 55. Furthermore, on the upper surface of the support portion 55, a rail portion 56 that holds the nozzle holder 58 so as to be able to advance and retreat in the direction of the axis of the nozzle 20 extends from the rear toward the front.

And the nozzle 20 is inserted in the through-hole of this guide part 57 so that advance / retreat and rotation are possible. The guide portion 57 is made of a material having good slidability. Further, an appropriate clearance is provided between the guide portion 57 and the nozzle 20 so that the nozzle 20 can smoothly rotate and slide in the through hole. Yes.

  Thereby, as shown in FIGS. 5A and 5B, the nozzle holder 58 slides (advances and retreats) along the rail portion 56 in the direction of the axis of the nozzle 20. The nozzle 20 moves forward and backward along the rail portion 56 in accordance with the movement of the nozzle holder 58.

  Next, the advancing / retreating drive means 81 that is fixed to the support portion 55 and drives the nozzle 20 and the nozzle holder 58 to advance / retreat in the axial direction of the nozzle 20 will be described.

  The first connecting means 82 is mainly connected to the driving pulley 60, the driven pulley 59a, the driven pulley 59b, the tension pulley 59c, and these four pulleys, and drives the rotational motion of the rotating shaft of the first electric motor 53. The timing belt 61 is transmitted to the driven pulley 59a and the driven pulley 59b via the pulley 60.

  Here, in the first electric motor 53, the axial direction of the rotation axis is substantially parallel to the normal direction of the side surface at the substantially right-angled corner portion of the side surface (side surface having a substantially right triangle shape) of the support portion 55. It is arranged to become. Furthermore, the driving pulley 60 has a through-hole that serves as the center of rotation. The rotating shaft of the first electric motor 53 is fitted in the through hole of the driving pulley 60, and the driving pulley 60 is fixed to the first electric motor 53 so as to be able to rotate forward and backward.

  The driven pulley 59a has a corner on the side close to the guide 57 among the corners on the side of the support 55 where the driving pulley 60 is disposed, and the axial direction of the rotation axis is substantially parallel to the normal to the side. It is arranged to become. The driven pulley 59b has an axial direction of a rotation axis substantially parallel to a normal direction of the side surface at a corner portion on the side close to the nozzle holder 58 among the corner portions on the side surface of the support portion 55 where the driving pulley 60 is disposed. Are arranged as follows.

  The timing belt 61 surrounds the driving pulley 60, the driven pulley 59a, and the driven pulley 59b, and is in contact with the respective rotation surfaces.

  As a result, the timing belt 61 can transmit the rotational motion of the rotation shaft of the first electric motor 53 to the driven pulley 59a and the driven pulley 59b via the driving pulley 60.

  Further, the tension pulley 59c is driven by the driving pulley 60 and the driven pulley 60 so that the timing belt 61 positioned between the driving pulley 60 and the driven pulley 59a can be pressed by the rotating shaft on the side surface of the support portion 55 where the driving pulley 60 is disposed. It arrange | positions so that the axial direction of a rotating shaft may become substantially parallel with the normal line direction of the said side surface between pulley 59a. Thereby, the tension of the timing belt 61 can be sufficiently held.

  Further, the portion of the timing belt 61 positioned between the driven pulley 59a and the driven pulley 59b is arranged so that the rotational direction thereof is substantially parallel to the axial direction of the rail portion 56.

  An arm portion 58a provided on the nozzle holder 58 is connected to a portion of the timing belt 61 located between the driven pulley 59a and the driven pulley 59b. As a result, the nozzle holder 58 and the nozzle 20 are driven back and forth in the axial direction of the nozzle 20 along the rail portion 56 in accordance with the movement of the timing bell 61 that is moved by the rotation of the first electric motor 53.

  Next, the rotation means 80 that is fixed to the support portion 55 and that rotates the nozzle 20 about its axis as a rotation center will be described.

  The rotation means 80 is mainly connected to the second electric motor 54 fixed to the support portion 55, the second electric motor 54 and the nozzle 20, and rotates the shaft of the second electric motor 54. And second connecting means 83 for converting into 20 rotational drives.

  The first transmission means 84 mainly includes a gear A62 and a gear B63. The gear A62 is engaged with the shaft of the second electric motor 54. Further, the gear B 63 is integrally fitted to the rear end portion of the shaft 66.

  Both ends of the shaft 66 are rotatably supported by the support portion 55 so as to be substantially parallel to the axis of the nozzle 20.

  The rotating body 85 includes a gear C64 and a gear D65 that mesh with each other, and the gear C64 is fixed to the nozzle holder 58 so as to be interlocked with the advance / retreat drive of the nozzle 20, and can rotate in conjunction with the rotation of the shaft 66. Further, the shaft 66 is fitted. That is, the gear C64 has a hole having a square cross-sectional shape at the center, and the shaft 66 is slidably fitted in this hole. The gear D65 is directly connected to the rear end of the nozzle 20 and is rotatably held by the nozzle holder 58. Therefore, the rotation operation of the gear C64 becomes the rotation operation of the nozzle 20.

  As described above, in the rotating means 80, the nozzle 20 rotates in accordance with the forward / reverse rotation of the second electric motor 54, and the air jet spouted from the air outlet 21 swings in the right and left directions of C and D in FIG. To do.

  In this embodiment, the gear A62 and the gear B63 are used as the first transmission means 84. However, in the present invention, the configuration of the first transmission means is not limited to this. For example, the first transmission means 84 may employ a configuration in which the second electric motor 54 and the shaft 66 are directly connected and the rotation of the second electric motor 54 is directly transmitted to the shaft 66. In this case, since the gear A62 and the gear B63 are not required, the power transmission loss and power transmission failure of the second electric motor can be sufficiently reduced. In addition, manufacturing costs (reducing parts costs, reducing the occurrence of defective products by reducing assembly work, etc.) can also be achieved.

  Next, the nozzle cleaning means 35 will be described in detail with reference to FIG.

  FIG. 6A is a schematic diagram showing a transverse section of the nozzle cleaning means 35 in the sanitary cleaning apparatus 100 shown in FIG. FIG. 6B is a schematic view showing a longitudinal section of the nozzle cleaning means 35 in the sanitary washing apparatus 100 shown in FIG.

  The nozzle cleaning means 35 shown in FIGS. 6A and 6B is configured integrally with the guide portion 57.

  The nozzle cleaning means 35 includes a water inlet 36, a cleaning chamber 37, and a cleaning water diffusion unit 38. The cleaning water is supplied from the water inlet 36 and collides with a step of the cleaning water diffusion unit 38 and diffuses into the cleaning chamber 37. Has been. In this way, the cleaning water is configured to wash away the surface of the nozzle 20.

  Next, the configuration of the nozzle unit centered on the nozzle 20 will be described with reference to FIG.

FIG. 7A is a front view when the nozzle 20 in the sanitary washing device 100 shown in FIG. 1 is viewed from the air outlet 21 side. FIG. 7B is a cross-sectional view when the nozzle 20 is cut along the line AA shown in FIG. FIG.7 (c) is sectional drawing at the time of cut | disconnecting the nozzle 20 (state when a user selects drying setting) along the BB line shown to (a). FIG.7 (d) is sectional drawing at the time of cut | disconnecting the nozzle 20 (state when a user has selected the buttocks washing setting) along the BB line shown to (a). FIG. 7E is a cross-sectional view when the nozzle 20 (a state where the user has selected the bidet setting) is cut along the line BB shown in FIG.

  The nozzle 20 shown in FIG. 7 has a cylindrical shape (cylindrical shape), and is provided with an air jet 21, a first washing water jet 22, and a second washing water jet 23 in the outer peripheral direction near the tip. An air passage 24 for introducing pressurized air into the air jet 21, a water passage a 25 and a water passage b 26 for guiding the washing water for rinsing washing to the first washing water jet 22, a bidet A water flow path c <b> 27 for guiding the cleaning water for cleaning to the second cleaning water outlet 23 is provided.

  A nozzle cover 28 that covers the outer peripheral surface of the nozzle 20 and is provided rotatably is disposed on the outer peripheral portion of the nozzle 20, and one opening facing the cleaning water outlets 22, 23 and the air outlet 21 of the nozzle 20. A portion 29 is formed.

  Therefore, by changing the relative angle between the nozzle 20 and the nozzle cover 28, the desired outlet can be switched to the opening 29. FIG. 7C shows a case where the opening 29 and the air jet 21 are matched, and FIG. 7D shows a case where the opening 29 and the first washing water jet 22 are matched, as shown in FIG. ) Shows a case where the opening 29 and the second washing water outlet 23 are matched. In this way, the outlet can be easily switched according to the operation mode.

  Since the first washing water jet port 22 synthesizes and jets the swirl flow from the water flow path a25 to the parallel flow from the water flow path b26, by adjusting the ratio between the parallel flow and the swirl flow The spread and strength of the jet can be changed.

  The nozzle cover 28 is made of a pipe-like stainless metal, so that bacterial growth is suppressed and hygiene can be improved.

  The pressurized air from the air pump 51 is supplied to the air flow path 24 from the air inlet 45a connected to the tube 39a. Further, the wash water from the switching valve 32 is supplied to the water flow path 26 from the wash water inlet 45b connected to the tube 39b.

  Similarly, a washing water inlet (not shown) and a washing water inlet (not shown) are formed in the water channel 25 and the water channel 27, respectively, and a tube 39c and a tube 39d (see FIG. 5), respectively. Is connected.

  In these four tubes 39a, 39b, 39c, and 39d, stress (restoring force) against twisting or bending is generated when the nozzle 20 is rotated or driven back and forth. Therefore, from the viewpoint of reducing this force, the four tubes 39a, 39b, 39c, and 39d are made of a flexible material such as rubber or elastomer as a constituent material.

  The air inlet 45 a, the cleaning water inlet (not shown), the cleaning water inlet 45 b, and the cleaning water inlet (not shown) are disposed inside the cylindrical nozzle holder 58. With this configuration, when the tubes 39a, 39b, 39c, and 39d are connected to the air inlet 45a, the washing water inlet, the washing water inlet 45b, and the washing water inlet and bent into a U shape, the rear end of the nozzle 20 is formed. The size of the part can be reduced. Therefore, since the nozzle 20 can be configured in a compact manner, when the nozzle 20 is stored in the main body 200, the nozzle 20 can be easily stored in the main body 200.

Next, a configuration for setting the angles of the nozzle cover 28 and the nozzle 20 will be described with reference to FIG. FIG. 8A is a side view of the driving means 52 when the nozzle 20 is housed in the sanitary washing device 100 shown in FIG. FIG. 8B is a partial cross-sectional view when the nozzle 20 and the driving unit 52 are cut along the line AA shown in FIG. FIG. 8C is a partial cross-sectional view when the nozzle 20 and the driving unit 52 are cut along the line BB shown in FIG.

  The stopper 71 is disposed at the rear portion of the support portion 55. When the nozzle moves to the final end of the forward / backward drive (front / rear drive) and enters the retracted state, the arm 73 of the nozzle cover 28 is accommodated inside the stopper 71 so that the nozzle cover 28 rotates in the retracted state. The range will be limited. If the nozzle 20 is rotationally driven in this state, the relative angle between the nozzle 20 and the nozzle cover 28 can be changed.

  Further, as shown in FIG. 8B, the stoppers 71 are provided on both the left and right sides of the nozzle 20, and the angle can be changed from any direction.

  Similar to the stopper 71, the stopper 72 is also arranged on both the left and right sides of the nozzle holder 58. The stopper 72 is configured not only to limit the rotation range of the nozzle cover 28 but also to limit the rotation angle of the nozzle 20. In other words, when the arm 73 of the nozzle cover 28 comes into contact with the stopper 72, the arm 20a of the nozzle 20 also comes into contact with the stopper 72. Thereby, the nozzle 20 and the nozzle cover 28 are set to be regulated within the same rotation range.

  The relative angle between the nozzle 20 and the nozzle cover 28 can also be changed by further rotating the nozzle 20 in a state where the arm 73 of the nozzle cover 28 is in contact with the stopper 72.

  As shown in FIG. 8C, the angle holding means 74 that holds the relative angle between the nozzle 20 and the nozzle cover 28 at a predetermined angle includes a convex portion 75 having a spring property formed on the nozzle cover 28, and the outer periphery of the nozzle 20 It consists of three concave portions 76a, 76b, 76c provided on the surface, and is configured such that the convex portion 75 and one concave portion are fitted. Thereby, the relative angle between the nozzle 20 and the nozzle cover 28 can be held at a predetermined angle.

  The control operation in the control unit 150 will be described below with reference to FIGS.

  Next, at the elapsed time T17, the first electric motor 53 is operated to move the nozzle to the storage position (about 10 mm backward). Then, the operation is completed at T18.

  By the operation from the elapsed time T11 to the elapsed time T18, the angle of the second wash water jet port 23 for bidet can be matched with the opening 29 of the nozzle cover 28, and the jet direction can be set upward. .

  Next, an operation when the user presses the drying switch 314 of the remote control device 300 will be described.

Also in this case, when the operation has not been performed yet, the front-rear direction of the nozzle 20 is disposed at the rear end storage position, and the left-right direction of the nozzle 20 is set to an angle at the center position provided in the rotation means 80. It shall be. However, the direction of the opening 29 of the nozzle cover 28 is undetermined.

  First, at the elapsed time T21, the first electric motor 53 is operated and moved to a position where the arm 73 and the stopper a71 do not interfere (approximately 10 mm forward). Next, at the elapsed time T22, the second electric motor 54 is rotated to change the angle to the right end angle (+ 90 °) at which the nozzle 20 hits the stopper b72. If the opening 29 of the nozzle cover 28 coincides with the first washing water jet port 22 at the elapsed time T22, the arm 73 hits the stopper b72, and the relative angle between the nozzle cover 28 and the nozzle 20 changes. The angle changes until the air outlet 21 and the opening 29 of the nozzle cover 28 coincide.

  Next, the second electric motor 54 is reversed at the elapsed time T23, and the angle is changed to the left end angle (−180 °) at which the nozzle 20 hits the stopper b72 on the opposite side. If the opening 29 of the nozzle cover 28 coincides with the second washing water jet 23 at the time T23, the arm 73 hits the stopper b72 on the opposite side, and the nozzle cover 28 is relative to the nozzle 20. The angle changes until the air outlet 21 and the opening 29 of the nozzle cover 28 coincide with each other.

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

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

  Next, at the elapsed time T25, the first electric motor 53 is operated to move the nozzle to the storage position (about 10 mm backward). Then, the operation is completed at the elapsed time T26.

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

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

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

As shown in FIG. 10, at the time of elapsed time T0 (the time when elapsed time is zero) when the operation is not yet performed, the front-rear direction of the nozzle 20 is arranged at the rear end storage position. The left-right direction of the nozzle 20 is set at an angle to a detection position of a position sensor (not shown) that detects the center position provided in the rotation means 80 .

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

  At the time T2 (elapsed time T2) when the temperature of the hot water from the hot water heating means 31 reaches a predetermined temperature (for example, 36 ° C.), the hot water heating means 31 and the on-off valve 34 are stopped, and the first electric motor 53 is operated. The nozzle 20 is advanced to the center position (for example, 100 mm forward).

  Then, at the elapsed time T3, the operation of the hot water heating means 31 and the on-off valve 34 is restarted, and the cleaning water is jetted onto the surface to be cleaned of the user. Electric power control to the hot water heating means 31 is performed using known PID or FF control so that the temperature detected by a temperature sensor (not shown) for detecting the temperature of the hot water becomes a set temperature (for example, 40 ° C.). The flow rate of the washing water is set to a user's favorite amount by adjusting the valve opening degree of the switching valve 32. As shown in FIG. 11 (a), the wet state of the surface to be cleaned in this butt cleaning is not only the central portion where the cleaning water directly hits but also the water droplets flow to wet the peripheral portion.

At the elapsed time T4 when the butt washing is completed and the user depresses the stop switch 311 of the remote control device 300, the hot water heating means 31 and the on-off valve 34 are stopped, and the switching valve 32 is moved to the first washing water jet 22. The direction is switched from the direction to the nozzle cleaning means 35 to stop the ejection of the cleaning water from the nozzle 20, and at the same time, the first electric motor 53 is reversely rotated to move the nozzle 20 back to the storage position, thereby completing the cleaning operation.

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

  Next, at an elapsed time T5a after the elapse of a predetermined time from the elapsed time T4, the opening / closing valve 34 is opened, and cleaning water is supplied from the water inlet 36 in the nozzle cleaning means 35 of FIG. The nozzle is cleaned by spraying cleaning water on it.

  Then, the on-off valve 34 is stopped at the elapsed time T5b shown in FIG. 10 to finish the nozzle cleaning. This operation pre-cleans the nozzles assuming that a “dry” operation is selected.

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

At the same time, the air pump 51 is operated for a short time (for example, 1 second), and the pressurized air is ejected from the air outlet 21 of the nozzle 20 for a moment. This operation, the nozzle 20 distal to the cleaning chamber 37 is accommodated state, by ejecting pressurized air from the air Kibuki unloading port 21, since the cleaning chamber 37 pressurized air flows at high speed along the nozzle 20 The water droplets adhering to the surface of the nozzle 20 are blown off. Therefore, reattachment of water droplets to the user is prevented.

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

  Thereafter, the first electric motor 53 is operated to advance the nozzle 20 to the most advanced position (for example, 150 mm forward), while the second electric motor 54 is operated to set the right / left angle of the nozzle 20 to the right end angle (for example + 50 °). Change the angle until).

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

  In the first step from the elapsed time T8 to the elapsed time T9, the driving direction and the driving speed of the second electric motor 54 and the first electric motor 53 of the driving means 52 are controlled, and the front-rear driving of the nozzle 20 is within a predetermined range. The reciprocating operation is performed at high speed (for example, 50 mm to 150 mm forward), and at the same time, the left and right angles of the nozzle 20 are slowly driven from the right end angle toward the center angle from the right end angle (for example, + 50 ° to + 20 °).

  In the operation of the first step, the air jet from the nozzle 20 gradually approaches the center while moving at a high speed in the front-rear direction from a predetermined position on the right side of the surface to be dried of the user. Therefore, as shown in the operation pattern P1 of FIG. 12, the air jet contact area E gradually moves toward the center G while periodically moving in the tangential direction of the right end of the surface F to be dried. Since it moves, a zigzag movement trajectory is drawn as shown in the figure.

As a result, as shown in FIG. 11 (b), since the start sufficiently ejected from the outer pressurized air than spouting range of washing water, the water droplets attached spread to the right of the drying surface, the center direction Can be blown away while collecting.

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

  In the second step from the elapsed time T10 to the elapsed time T11, the front-rear drive of the nozzle 20 is reciprocated at a high speed within a predetermined range (for example, 50 mm to 150 mm forward) as in the first step. Drive slowly from the angle toward the center angle from the left to a predetermined angle (eg, -50 ° to -20 °).

  The operation of the second step is that the air jet from the nozzle 20 gradually moves toward and approaches the center while moving periodically at a high speed in the front-rear direction from a predetermined distance on the left side of the surface to be dried of the user. come. Therefore, as shown in the operation pattern P2 of FIG. 12, the contact range E of the air jet gradually moves toward the center G while periodically moving in a tangential direction at the left end of the surface F to be dried. Since it moves gradually, a zigzag movement trajectory is drawn as shown in the figure. As a result, as shown in FIG. 11C, water droplets spreading and adhering to the left side of the surface to be dried can be blown away while being collected in the central portion direction.

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

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

  At the end time T11 (elapsed time T11) of the second step, the nozzle 20 is advanced to the most advanced position. In the third step from the elapsed time T11 to the elapsed time T12, the left and right angle of the nozzle 20 is reciprocated at high speed from the right end angle to the left end angle at the same time while slowly moving the nozzle 20 back and forth from the most advanced position toward the center. Drive.

  In the operation of the third step, the air jet from the nozzle 20 gradually approaches the center from the predetermined position in the front to the back while moving at high speed in the left-right direction on the surface to be dried. Therefore, as shown in the operation pattern P3 of FIG. 13, the contact range E of the air jet gradually moves toward the center portion G while periodically moving in a tangential direction at the tip of the surface F to be dried. Since it moves novelly, a zigzag movement trajectory is drawn as shown in the figure. As a result, water droplets remaining in front of the center portion G of the surface to be dried can be blown away while being collected in the direction of the center portion G.

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

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

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

  Next, the action on water droplets adhering to the surface to be dried in the first step to the fourth step will be described. Since the driving direction of the air jet to the surface to be dried during the operation of each step is sufficiently faster than the moving speed toward the center, the moving speed in the tangential direction is sufficiently faster with respect to the center. The air flow direction which spreads by colliding with the surface to be dried increases the flow component in the direction perpendicular to the substantially tangential direction.

  Accordingly, the water droplets adhering between the air jet driven in the substantially tangential direction and the central portion are pushed by the air flow perpendicular to the tangential direction and move in the central portion direction. And since an air jet is gradually approached to a center part, it gathers in the center part direction. By performing this movement from the right, left, front, and rear four directions in the first to fourth steps, the water droplets are collected at the center. Thus, the first step to the fourth step are steps for collecting water droplets adhering to the surface to be dried at the center of the surface to be dried.

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

  Then, in the fifth step from the elapsed time T15 to the elapsed time T16, the front-rear drive of the nozzle 20 starts to retreat from a predetermined position in the front, passes through the center, and is a predetermined distance behind the center (for example, 50 mm forward). ) At the same time, the left and right angles of the nozzle 20 are reciprocated at high speed from the right end angle to the left end angle.

  The operation of the fifth step is as follows. The air jet from the nozzle 20 gradually moves backward from a predetermined position in the forward direction while periodically moving in a horizontal direction on the surface to be dried. It approaches the central part, and further moves gradually through the central part to a predetermined position behind it. Therefore, since the position where the air jet strikes the surface to be dried gradually moves from the front through the center and rearward, the water droplets remaining at the center of the surface to be dried can be completely blown away. That is, the fifth step is a process of blowing off the collected water droplets.

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

  From the elapsed time T17a to the elapsed time T17b, the nozzle 20 is cleaned by opening the on-off valve 34 while moving the nozzle 20 in the front-rear direction toward the storage position. During this time, washing water is sprayed on the entire nozzle 20 to clean the entire nozzle. At the elapsed time T17b, the on-off valve 34 is stopped and the nozzle cleaning is finished.

  After the drying is finished, the operation of the heater 43 is stopped at an elapsed time T18 when the user presses the stop switch 311 of the remote control device 300.

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

  As described above, in the present embodiment, the second electric motor 54 of the rotating unit 80 is fixed to the support portion 55.

  Therefore, in the present embodiment, the second electric motor 54 is fixed to the support portion 55 even when the nozzle 20 is driven forward and backward by the operation of the forward / backward driving means 81 of the nozzle 20. Therefore, in the sanitary washing apparatus of Patent Document 1 described above, it is not necessary to secure a movement space for moving the rotation driving means such as a motor and a movement space for wiring connected to the rotation driving means.

  Therefore, this embodiment can easily reduce the size of the entire apparatus, which is important when installed in a limited installation space such as on a toilet bowl.

  Further, in the present embodiment, since the wiring connected to the rotation means 80 does not move with the advance / retreat drive of the nozzle 20, sufficient reliability of the apparatus can be easily obtained when long-term use is assumed.

  Therefore, according to the present embodiment, even when the forward / backward drive means 81 and the rotation means 80 of the nozzle 20 are both provided, it is possible to easily and reliably obtain a compact size and sufficient reliability of the apparatus. become.

  Further, in the present embodiment, when the nozzle 20 is driven to rotate by the operation of the rotating means 80, the rotation of the second electric motor 54 in the rotating means 80 is the first of the second connecting means 83. Is transmitted from the first transmission means 84 to the shaft 66 of the second connecting means 83, and is transmitted from the shaft 66 to the rotating body 85 of the second connecting means 83 for rotation. The nozzle 20 is rotated by being transmitted from the body 85 to the nozzle 20.

  In addition, the second electric motor 54 of the rotation means 80 is fixed to the support portion 55, and the first transmission means 84 and the shaft 66 of the second connecting means 83 of the rotation means 80 are also the support portion 55. It is fixed to. On the other hand, of the second connecting means 83 of the rotating means 80, only the rotating body 85 is configured to move in conjunction with the advance / retreat drive of the nozzle 20.

  Therefore, when the nozzle 20 is driven forward / backward by the operation of the forward / backward driving means 81, only the rotating body 85 moves in conjunction with the forward / backward drive of the nozzle 20. Therefore, it is not necessary to secure a moving space for the second electric motor 54 occupying a large volume in the rotating means 80 and a moving space for wiring connected to the second electric motor 54.

  In the case of this configuration, the rotating body 85 of the rotating means 80 moves in conjunction with the advance / retreat operation of the nozzle 20, but the movement space of the second electric motor 54 itself is the advance / retreat operation of the nozzle 20. It is possible to easily make it extremely small as compared with the case of moving in conjunction with.

  The reason is the following three points. That is, firstly, the first transmission means 84 constituted by the gear A62 connected to the rotating shaft of the second electric motor 54 and the gear B63 connected to the shaft 66 is the second electric motor 54. This is because the volume can be made relatively small so that it can be arranged in a relatively small space at the tip of the rotating shaft. Secondly, the diameter of the shaft 66 connected to the first transmission means 84 can be easily set to a level substantially equal to the diameter of the rotation shaft of the second electric motor 54. Third, the volume of the rotating body 85 fitted to the shaft 66 (having a relatively small diameter) can be easily reduced in volume, such as the gear C64 and the gear D65 that mesh with each other.

Furthermore, in the present embodiment, an inevitable space for providing a tube 39a for supplying pressurized air to the air outlet 21 at the tip of the nozzle 20 is required. Further, when the cleaning water jets 22 and 23 for jetting cleaning water for cleaning the human body part are provided at the tip of the nozzle 20, a tube 39b for supplying the cleaning water to the cleaning water jets 22 and 23 is provided. , 39c and 39d are inevitable.

  On the other hand, the shaft 66 is arranged substantially parallel to the axis of the nozzle 20 with respect to the nozzle 20. Therefore, it is possible to easily secure a sufficiently small installation space in which the above-described tubes 39a, 39b, 39c, and 39d can be arranged in an orderly manner between the nozzle 20 and the shaft 66 (rotating means). Moreover, when installing the above-described tubes 39a, 39b, 39c, 39d, the portions of the tubes 39a, 39b, 39c, 39d along the nozzle 20 and the shaft 66 are set to the axes of the tubes 39a, 39b, 39c, 39d. The nozzle 20 and the shaft 66 can be arranged substantially parallel to each other. In this way, even when the tubes 39a, 39b, 39c, 39d described above are driven forward / backward in conjunction with the advance / retreat drive of the nozzle 20, the nozzle 20 and the shaft 66 of the tubes 39a, 39b, 39c, 39d Since the portion along the line is accommodated in the space formed between the nozzle 20 and the shaft 66 described above, it is easy to sufficiently reduce the moving space for driving the pipe forward and backward.

  Further, in this configuration, when the above-described tubes 39a, 39b, 39c, 39d are driven forward / backward in conjunction with the advance / retreat drive of the nozzle 20, an excessive mechanical stress (load) applied to the tubes 39a, 39b, 39c, 39d is applied. It can also be sufficiently reduced. Therefore, in the case of this configuration, it becomes easy to sufficiently secure the lifetime of the tubes 39a, 39b, 39c, and 39d, so that the reliability of the piping can be obtained easily and reliably.

  Further, in the present embodiment, the first connecting means 82 is configured to connect the first electric motor 53 and the nozzle holder 58 with the timing belt 61, so the first connecting means 82 is configured with a relatively simple configuration. It becomes possible to easily convert the rotational movement of the electric motor 53 into the forward / backward drive of the nozzle 20.

  Furthermore, since the pressurized air for drying is ejected from the single air jet 21, the flow velocity of the air jet can be increased even at a low flow rate, and high drying performance can be obtained even with a small capacity air pump 51. It is done. That is, since the flow velocity of the jet is large, the energy for peeling off the water droplet when the jet hits the water droplet attached to the surface to be dried increases, so that the water droplet can be efficiently blown off.

  In the present embodiment, the configuration in which the driving means is shared is described as the configuration in which cleaning and drying are performed with one cylinder (nozzle 20), but the present invention is not limited to this. In the present invention, for example, a nozzle having a configuration for cleaning and a nozzle having a configuration for drying may be provided independently, and a driving unit corresponding to two nozzles may be provided.

  Moreover, in this embodiment, although the flow rate of the pressurized air was 20-50 m / s, this invention is not limited to this. In order to obtain the effect of blowing water droplets, a minimum speed of 10 m or more is necessary. The size of the nozzle hole and the number of nozzle holes, which are the setting elements of the size of the jet contact area, are determined by the air pump capability and the flow rate of the pressurized air. It is necessary to select in consideration of. Therefore, in the present invention, in consideration of these points, the flow rate of pressurized air that can obtain the effect of blowing water droplets may be set.

Furthermore, although the first step to the fifth step are sequentially executed in the present embodiment, the present invention is not limited to this. In the present invention, for example, each step may be repeatedly executed, or the order of each step may be changed. Also, the first and second steps may be omitted, and the third and fourth steps may be omitted.

  In the present embodiment, the heater is energized before the air fan is operated at the start of the drying operation to increase the speed of the heater temperature. However, the present invention is not limited to this. In the present invention, for example, the heater temperature may be increased at a high speed by simultaneously starting the air fan and the heater, and then providing a soft start function that gradually increases the air flow rate when the air fan is started.

(Second Embodiment)
FIG. 14 shows a schematic diagram of the rotating means of the sanitary washing device according to the second embodiment of the present invention. FIG. 14A shows a state in which the nozzle is housed, and FIG. 14B shows a state in which the nozzle is advanced.

  The sanitary washing apparatus according to the second embodiment differs from the sanitary washing apparatus according to the first embodiment in the following points.

  The second connecting means 91 of the turning means 90 in FIG. 14 is fixed to a shaft 94 inserted so as to be able to transmit the rotation of the second electric motor 93 to the nozzle 92, and a support portion 95. And a transmission means 96 for transmitting the rotation of the second electric motor 93 to the shaft 94.

  The nozzle 92 has a hole having a square cross section into which the shaft 94 is slidably inserted. The shaft 94 has a square cross section, and a rear end portion not inserted into the nozzle 92 is rotatably fixed to the support portion 95. The rotation of the shaft 94 is transmitted to the nozzle 92 by meshing the section of the shaft 94 with the section of the hole of the nozzle 92.

  The second electric motor 93 and the transmission means 96 are the same as those in the first embodiment, and a description thereof will be omitted.

  As described above, in the sanitary washing device of the second embodiment, since the shaft 94 is inserted into the nozzle 92, the second connecting means 91 is compared with the case where the shaft 94 is provided outside the nozzle 92. Installation space can be reduced. Further, since the rotational power can be directly transmitted from the shaft 94 to the nozzle 92, the power transmission loss and power transmission failure of the second electric motor 93 can be sufficiently reduced. In addition, manufacturing costs (reducing parts costs, reducing the occurrence of defective products by reducing assembly work, etc.) can also be achieved.

  The sanitary washing apparatus according to the first embodiment to the second embodiment of the sanitary washing apparatus according to the present invention has been described above, but the sanitary washing apparatus according to the present invention is the sanitary washing apparatus according to the first embodiment to the second embodiment described above. It is not limited.

  For example, in the sanitary washing device according to the present invention, the cross section of the shaft is not limited to a square like the cross section shown in FIG. In the sanitary washing device of the present invention, the shape of the cross section of the shaft is not particularly limited as long as the rotation of the shaft can be transmitted to the gear C. For example, the cross-sectional shape of the shaft may be a D-cut cylinder or a cylinder having a groove.

  The sanitary washing device of the present invention can efficiently dry water droplets even with a small amount of air, and can be dried. Therefore, the sanitary washing device can be applied to drying a body wet by showering or hand washing. Moreover, it can apply suitably to the field | area and use of washing machines, such as a dishwasher, a car wash machine, and a parts washing machine.
