Description

  The present invention relates to a sanitary washing apparatus that cleans and dries a human body part, and more particularly, to a sanitary washing apparatus that has a notification function for notifying drying time information.

  In the field of a sanitary washing apparatus that is installed on the upper surface of a toilet bowl 600 of a toilet and cleans a local part of a human body, various proposals have been made to improve the user's convenience. For example, by setting and registering in advance the operation contents of the cleaning function for cleaning the human body part and the drying function for drying the human body part after the cleaning, the user can automatically perform all operations only by giving an instruction to start the first operation. A sanitary washing device has been proposed that operates automatically and terminates the operation automatically.

  As a sanitary washing apparatus having such an automatic operation function, an apparatus having an informing means for confirming setting registration contents for automatic operation is known (for example, see Patent Document 1 below).

  FIG. 15 is a schematic diagram showing an operation unit of a conventional sanitary washing device described in Patent Document 1. As shown in FIG. 15, the operation patterns of the cleaning function and the drying function can be set and registered in advance. When a user wants to execute a pattern set and registered as a specific pattern number, automatic progress can be executed simply by pressing the pattern number selection button 103 corresponding to the pattern number.

  It is confirmed by the operation of the registration / content display button 101 what pattern is set and registered for each pattern number. When the registration / content display button 101 of the operation unit is pressed once, “Registered” is lit on the liquid crystal panel 102 and only the number corresponding to the pattern number that has been set and registered is lit.

  When the registration / content display button 101 is subsequently pressed, “content display” is lit on the liquid crystal panel 102, and when the pattern number selection button 103 is further pressed, the contents of the preset registration pattern are displayed on the liquid crystal panel 102. It is configured so that it can be confirmed.

  However, even the conventional sanitary washing device described in Patent Document 1 still has room for improvement from the viewpoint of ease of use.

  That is, as described above, in the sanitary washing device described in Patent Document 1, the operating time setting values of the cleaning function and the drying function can be confirmed, but the progress of cleaning and drying during operation is confirmed. Because I don't know, I was worried and dissatisfied that I didn't know when the operation would end.

Since the cleaning function is generally completed in a short time, there is not much problem. However, since the drying function needs to finally evaporate water droplets adhering to the human body part and dry it, a long time is required. Therefore, when the drying operation is started, it is possible for the user not to know the elapsed time and end timing to feel that the waiting time is long, the setting is wrong, or the failure is suspected. .

  The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide a sanitary washing apparatus that can be used with peace of mind because the progress status can be grasped in the automatic operation of the drying function.

  In order to solve the above-described problems of the prior art, a sanitary washing device according to the present invention includes a cleaning unit that cleans a human body part, a drying unit that dries a human body part wet by the cleaning unit, the cleaning unit, and the drying unit. An informing means for informing the operation state of the means, an input means for instructing operation condition setting, operation start and operation stop of the cleaning means and the drying means, and the cleaning means and the drying in response to a signal of the input means Control means for controlling operation of the means and outputting notification information to the notification means, and the control means automatically stops the drying means at a predetermined time required for drying from the start of operation. The operation time information of the drying means is notified by the notification means (claim 1).

  As described above, the sanitary washing device of the present invention notifies the operation time information when the user performs the automatic operation of the drying means, so that the user can check the progress of the drying operation. Don't worry about not knowing when driving will end. Therefore, the sanitary washing device of the present invention can provide a sanitary washing device that can be used with confidence because the progress status can be grasped in the automatic operation of the drying function.

  The count-down time until the end of the operation of the drying means is notified by the notification means (claim 2).

  With this configuration, the user can directly check the progress of the drying operation and the waiting time until the end of the operation, so that the anxiety and dissatisfaction of the waiting time until the end of the drying operation can be further eliminated.

  Further, in the sanitary washing device of the present invention, the control means automatically stops the drying means for an extended set time obtained by adding a delay time to a predetermined time required for drying, and also displays operation time information up to the predetermined time. It is made to alert | report by the said alerting | reporting means (Claim 3).

  In this case, the notifying means notifies the user of time elapsed information necessary for drying, and the drying operation continues even after a predetermined time has elapsed. And a user is comprised so that driving | operation may stop itself based on this time information. That is, the user determines the local dry state from the time information and stops the operation in a favorite state, so that the satisfaction degree of the user with respect to the dry state can be improved.

  In addition, when water droplets adhering to a human body part are evaporated and dried by a drying operation using only general warm air, drying for a long time is unavoidable. From the viewpoint of shortening the drying time, in the sanitary washing apparatus of the present invention, the drying means dries the water droplet removing means for removing water droplets adhering to the human body local portion with pressurized air, and the human body local portion with hot air. A hot air means, and the control means automatically stops the water drop removing means and the hot air means, respectively, and causes the notifying means to notify at least operation time information of the water drop removing means (claim 4).

  Moreover, in the sanitary washing apparatus of the present invention, when the above-described configuration (Claim 4) is adopted, the control means obtains the operation time information of the shorter automatic stop time of the water drop removing means and the hot air means. It is preferable that the notification means notify the user and when one of them stops, the information is switched to the other driving time information and notified by the notification means (Claim 5).

  In this case, since the driving time information can be notified in order by a single notification means, it is easy to understand because information to be noticed by the user can be collected in one place. 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 more corresponding to the user's preference, in the sanitary washing apparatus of the present invention, the control means is preset with a plurality of operation times until the drying means is automatically stopped, and the user Since a desired operation time can be selected from among the operation times, the drying time and the degree of drying can be selected according to the user's preference, and a more user-friendly sanitary washing device can be provided ( Claim 6).

  According to the present invention, it is possible to provide a sanitary washing device that can be used with confidence because the progress status can be grasped in the automatic operation of the drying function.

Further, FIG. 6C shows the support portion 55, the nozzle holder 58, and the tube 39 when the driving means shown in FIG. 6B is seen through from the direction of the line of sight L1 shown in FIG. 6B (the axial direction of the nozzle 20). And is a perspective sectional view showing the positional relationship of a shaft 66.

  As shown in FIG. 6, the driving means 52 is mainly integrated with a cylindrical nozzle 20 having an air outlet 21 for jetting pressurized air in the direction of the human body portion at the tip and a rear end of the nozzle 20. And a nozzle holder 58 that supports the nozzle 20 so as to be rotatable about its axis, and a support that supports the nozzle 20 and the nozzle holder 58 so as to advance and retreat in the direction of the axis of the nozzle 20. The part 55 and the support part 55 are fixed, and the nozzle 20 and the nozzle holder 58 are driven forward and backward in the axial direction of the nozzle 20, and the support part 55 is fixed, and the axis of the nozzle 20 is rotated. It has a configuration including a rotation means for rotating the nozzle 20 as a center.

  According to the driving means 52 having the above-described configuration, the contact range of the pressurized air ejected from the nozzle 20 with respect to the surface to be dried can be arbitrarily moved over the entire surface to be dried of the user's local area.

  Four tubes 39 (tube 39a, tube 39b, tube 39c, and tubes for supplying pressurized air and washing water to the nozzle 20 are respectively provided to the air inlet and the washing water inlet 45b of the nozzle 20. 39d) is connected.

  One of the four tubes 39 has one end connected to the air inlet of the nozzle 20 and the other one connected to the cleaning water inlet 45b 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 45b of the nozzle 20, so that the tubes are rotated as the nozzle 20 rotates. 39 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 45a or the washing water inlet 45b and the fixed portion so that the positioned state does not go out of the way with use.

More specifically, the four tubes 39 are bent in a U-shape when connected to the air inlet 45a or the washing water inlet 45b and the fixed portion. The so-called torsional action applied to each of the four tubes 39 is sufficiently reduced so that the positioned state of the nozzle 20 does not change with the course of use.

  Further, when the four tubes 39 are rotated (or moved) as the nozzle 20 is rotated, the tubes 39 are at a minimum with respect to the shaft 66 so that the four tubes 39 do not contact the shaft 66. It is arranged so that there is a gap.

  This will be described with reference to FIG. 6C as a representative example of the tube 39a of the four tubes 39.

  As shown in FIG. 6C, one end of the tube 39a is connected to an air inlet 45a (see FIG. 8) located inside the nozzle holder 58, and the other end of the tube 39a is outside the nozzle 20. It is fixed to a fixing part (not shown). And when it sees through from the direction of the line of sight L1 shown in FIG.6 (c), it goes out from the axial line L2 which connects the both ends of the tube 39a, and the axial center of the one end connected to the air inflow port 45a of the tube 36a. The angle θ with the extended virtual line L3 (a line L3 parallel to a line L4 substantially parallel to an installation surface of the support portion 55 described later) is adjusted as follows.

  That is, when the tube 39a rotates (or moves) with the rotation of the nozzle 20, even if the tube 39a approaches the shaft 66, it does not come into contact (the tube 39 is at a minimum distance from the shaft 66). The angle .theta.

  Next, the support part 55 will be described. In the case of this embodiment, the support portion 55 is configured to support the entire drive means 52.

  As shown in FIGS. 6A and 6B and FIG. 9A described later, the support portion 55 is a structure having a substantially triangular prism shape (the bottom surface is a substantially right triangle), and the triangular prism. Is erected in the main body 200 so that the side surface is the bottom.

  More specifically, when the support portion 55 is erected in the main body portion 200, the side surface having the largest area among the three side surfaces of the substantially triangular prismatic structure (a substantially rectangular shape including the long sides of the right triangle). 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. 6, and “rear direction” indicates the B direction. Specifically, the front direction is a direction that substantially matches the front direction as seen from the sight line of the user seated on the toilet seat 400, and the rear direction is substantially the same as the back direction as seen from the sight line of the user. Direction.

  On the upper surface of the support portion 55, the nozzle 20 is disposed in a forward inclined posture so that the tip end portion where the air ejection port 21 is formed is lowered. 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.

  A cylindrical guide portion 57 having a through hole is provided at the front end portion of the support portion 55 in front of the rail portion 56. 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.

  As a result, as shown in FIGS. 6A and 6B, 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, an advancing / retreating drive unit that is fixed to the support portion 55 and that drives the nozzle 20 and the nozzle holder 58 to advance / retreat in the axial direction of the nozzle 20 will be described.

  The advancing / retreating drive means is connected to the first motor 53 fixed to the support portion 55, the first motor 53 and the nozzle holder 58, and the rotational movement of the rotation shaft of the first motor 53 is determined by the nozzle 20 and the nozzle holder. And first connecting means for converting to 58 forward and backward drive.

  The first connecting means is mainly connected to a driving pulley 60, a driven pulley 59a, a driven pulley 59b, a tension pulley 59c, and these four pulleys. The timing belt 61 is configured to transmit the rotational motion of the motor to the driven pulley 59a and the driven pulley 59b.

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

The portion of the timing belt 61 located between the driven pulley 59a and the driven pulley 59b is arranged so that the rotation 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 motor 53.

  Next, a rotating means for rotating the nozzle 20 around its axis as a rotation center will be described. The rotating means is mainly connected to the second motor 54 fixed to the rear end of the upper surface of the support portion 55, the second motor 54 and the nozzle 20, and rotates the shaft of the second motor 54. And second connecting means for converting the nozzle 20 into rotational driving.

  The second connecting means mainly includes a shaft 66 having a square cross section, a first transmission means for transmitting the rotation of the second motor 54 to the shaft 66, and a rotating body for transmitting the rotation of the shaft 66 to the nozzle 20. It is composed of

  The first transmission means is mainly composed of a gear A62 and a gear B63. The gear A62 is fitted to the shaft of the second motor 54. The gear B63 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 includes a gear C64 and a gear D65 that mesh with each other. 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 is rotatable in conjunction with the rotation of the shaft 66. 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.

  Thus, the rotating means rotates the nozzle 20 in accordance with the forward and reverse rotation of the second motor 54, and the air jet ejected from the air outlet 21 swings to the right and left in C and D of FIG. .

  In this embodiment, the gear A62 and the gear B63 are used as the first transmission means, but the configuration of the first transmission means is not limited to this. For example, as the first transmission means, a configuration in which the second motor 54 and the shaft 66 are directly connected and the rotation of the second motor 54 is directly transmitted to the shaft 66 may be employed. 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, the manufacturing cost can be reduced by reducing the cost of parts and the generation of defective products by reducing assembly work.

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

  FIG. 7A is a schematic diagram showing a cross section of the nozzle cleaning means 35 in the sanitary cleaning apparatus 100 shown in FIG. FIG. 7B is a schematic diagram showing a longitudinal section of the nozzle cleaning means 35 in the sanitary cleaning apparatus 100 shown in FIG.

  As shown in FIGS. 7A and 7B, the nozzle cleaning means 35 is configured integrally with the guide portion 57 and includes a water inlet 36, a cleaning chamber 37, and a cleaning water diffusion portion 38. Since the cleaning water is supplied from the water inlet 36 and collides with the step of the cleaning water diffusion portion 38 and diffuses into the cleaning chamber 37, the cleaning water can wash 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. 8A 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. 8B is a cross-sectional view when the nozzle 20 is cut along the line AA shown in FIG. FIG. 8C is a cross-sectional view when the nozzle 20 (a state in which the user selects the drying setting) is cut along the line BB shown in FIG. FIG. 8D is a cross-sectional view when the nozzle 20 (a state in which the user selects the buttocks cleaning setting) is cut along the line BB shown in FIG. FIG. 8E is a cross-sectional view when the nozzle 20 (a state in which the user selects the bidet setting) is cut along the line BB shown in FIG.

  The nozzle 20 shown in FIG. 8 has a cylindrical shape (cylindrical shape), and is provided with an air outlet 21, a first cleaning water outlet 22, and a second cleaning water outlet 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 the first and second washing water outlets 22 and 23 of the nozzle 20 and the air outlet 21 are provided. One opening 29 is formed so as to be opposed to each other.

  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. 8C shows a case where the opening 29 and the air jet 21 are matched, and FIG. 8D 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. Moreover, the wash water from the switching valve 32 is supplied to the water flow path b26 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 a25 and the water channel c27, respectively, and a tube 39c and a tube 39d (see FIG. 6), 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 45b and are bent in a U shape, The size of the end 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. 9A 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. 9B 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. 9C 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 support portion 55 and the nozzle holder 58 shown in FIGS. 9A and 9B are provided with a stopper 71 and a stopper 72 which are rotation suppressing means for suppressing the rotation of the nozzle cover 28.

  The stopper 71 is disposed at the rear portion of the support portion 55. When the nozzle 20 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 can be rotated in the retracted state. The movement 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.

  As shown in FIG. 9B, 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. 9C, 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.

  Hereinafter, the control operation in the control unit 150 will be described with reference to FIGS.

  FIG. 10 shows the nozzle 20 outlets (air outlet 21, first washing water outlet 22, second outlet) in the “wet washing” operation, “bidet washing” operation, and “drying” operation by the control means 150. 4 is a time chart showing a control operation for setting a relative angle between the washing water outlet 23) and the opening 29 of the nozzle cover 28;

  FIG. 14 is a schematic diagram showing the movement pattern of the air jet on the surface to be dried when the sanitary washing apparatus 100 shown in FIG. 1 is in the operation state of the third step “drying” and the operation state of the fourth step.

  As shown in FIG. 10, at the time of elapsed time T0 (the time when elapsed time is zero) in a state where the operation has not been performed yet, the front-rear direction (forward and backward direction) of the nozzle 20 is disposed at the rear end storage position. The rotation direction of the nozzle 20 is set to an angle at a detection position of a position sensor (not shown) that detects the center position provided in the rotation means 70. This angle is a central angle, and the air outlet 21 of the nozzle 20 and the opening 29 of the nozzle cover 28 are set to coincide with each other. That is, the nozzle 20 is set to “dry”.

  At an elapsed time T1 when the user depresses the butt switch 312 of the remote control device 300 (see FIG. 2), the first motor 53 is operated to a position where the arm 73 and the stopper 71 do not interfere (approximately 10 mm forward). Moving.

  At this time, “cleaning” and “in preparation” of the liquid crystal panel 305 which is a notification means of the remote control device 300 are turned on. As a result, the user can recognize that the operation has been accepted even though the washing water has not been ejected.

  Next, at the elapsed time T2, the second motor 54 is rotated to change the angle to the left end angle (−90 °) at which the nozzle 20 hits the stopper 72.

  Next, at the elapsed time T3, the first motor 53 is operated to the storage position (about 10 mm rearward), and the arm 73 is moved so as to be fitted into the stopper 71. By this operation, the nozzle cover 28 is held at an angle by the stopper 71.

  Next, the second motor 54 is rotated at the elapsed time T4, and the nozzle 20 is rotated rightward so that the first washing water jet port 22 of the nozzle 20 and the opening 29 of the nozzle cover 28 coincide with each other. (About + 90 °). Here, when the nozzle 20 is rotated, the relative angle with the nozzle cover 28 in which the angle is maintained changes, and the rotation angle of the nozzle 20 with respect to the nozzle cover 28 can be changed.

Next, at the elapsed time T5, the first motor 53 is operated again and moved to a position where the arm 73 and the stopper 71 do not interfere with each other (about 10 mm forward). Then, the second motor 54 is rotated at the elapsed time T6, and the nozzle 20 is rotated rightward so that the first washing water jet port 22 of the nozzle 20 and the opening 29 of the nozzle cover 28 face upward. (About + 90 °).
At T7, the first motor 53 is operated to move the nozzle 20 to the storage position (about 10 mm backward). Then, the operation is completed at the elapsed time T8.

  By the operation from the elapsed time T1 to the elapsed time T8 as described above, the angle of the first washing water jet outlet 22 for washing the tail cover is matched with the opening 29 of the nozzle cover 28, and the ejection direction is set upward. it can.

  Next, an operation when the user presses the bidet switch 313 of the remote operation device 300 will be described.

  In this case, when the operation is not yet performed, the front-rear direction of the nozzle 20 is disposed at the rear end storage position, and the left-right direction of the nozzle 20 is angled with respect to the center position provided in the rotation means 70. It is assumed that it is set.

  First, at the elapsed time T11, the first motor 53 is operated and moved to a position where the arm 73 and the stopper 71 do not interfere with each other (about 10 mm forward). Next, at the elapsed time T12, the second motor 54 is rotated to change the angle to the right end angle (+ 90 °) at which the nozzle 20 hits the stopper 72.

  At this point of time, as in the buttocks cleaning, “cleaning” and “in preparation” of the liquid crystal panel 305 of the remote control device 300 (see FIG. 2) are turned on.

  Next, at the elapsed time T <b> 13, the first motor 53 is operated to the storage position (about 10 mm rear), the arm 73 is moved so as to be fitted into the stopper 71, and the nozzle cover 28 is held by the stopper 71.

  Next, the second motor 54 is rotated at the elapsed time T14, and the nozzle 20 is rotated leftward so that the second washing water outlet 23 of the nozzle 20 and the opening 29 of the nozzle cover 28 coincide with each other. (About -90 °).

  Next, at the elapsed time T15, the first motor 53 is operated again and moved to a position where the arm 73 and the stopper 71 do not interfere with each other (about 10 mm forward). Next, the second motor 54 is rotated at the elapsed time T16 to rotate the nozzle 20 counterclockwise so that the second washing water outlet 23 of the nozzle 20 and the opening 29 of the nozzle cover 28 face upward. (About -90 °).

  Next, at the elapsed time T17, the first motor 53 is operated to move the nozzle 20 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 is not yet performed, the front-rear direction of the nozzle 20 is disposed at the storage position at the rear end, and the left-right direction of the nozzle 20 is set to an angle at the center position provided in the rotating means 70. 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 motor 53 is operated and moved to a position where the arm 73 and the stopper 71 do not interfere (forward about 10 mm). Next, at the elapsed time T22, the second motor 54 is rotated to change the angle to the right end angle (+ 90 °) at which the nozzle 20 hits the stopper 72. If the opening 29 of the nozzle cover 28 coincides with the first washing water jet port 22 at the time T22, the arm 73 hits the stopper 72, 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.

  At this time, “drying” and “in preparation” of the liquid crystal panel 305 of the remote control device 300 (see FIG. 2) are turned on.

  Next, the second motor 54 is reversed at the elapsed time T23 to change the angle to the left end angle (−180 °) at which the nozzle 20 hits the stopper 72 on the opposite side. If the opening 29 of the nozzle cover 28 coincides with the second cleaning water jet 23 at the time T23, the arm 73 hits the stopper 72 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 20 faces the opening 29 of the nozzle cover 28.

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

  Next, at the elapsed time T25, the first motor 53 is operated to move the nozzle 20 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. 11 is “standard drying operation” in which the drying mode switch 320b shown in FIG. 2 is selected, and the hot air temperature adjustment switch 340 is set to “medium”. It is a time chart.

  In this “standard drying operation”, the time required for an operation that can sufficiently remove water droplets on the surface to be dried by injecting pressurized air from the water droplet removing means in the drying operation onto the surface to be dried is experimentally determined and set. The water droplet removing means is controlled to automatically stop. In FIG. 11, the time from elapsed time T8 to T16 corresponds to the required time. For example, the required time is 30 seconds.

  Further, the hot air means continues even after the operation of the water droplet removing means is finished, and the drying operation is not finished. The operation of the hot air means is controlled so as to automatically stop by an extended set time obtained by adding a delay time to the above required time. For example, the delay time is 60 seconds. However, in the time chart shown in FIG. 11, it stops manually before the automatic stop.

  As shown in FIG. 11, at the time of elapsed time T0 in a state where the operation has not been performed yet (time when elapsed time is zero), 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 70.

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 is set at the opening 29 of the nozzle cover 28 as described in 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 motor 53 is operated. The nozzle 20 is advanced to a 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 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. 12A, 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 and wet the peripheral portion.

  At this time, “preparing” at the top of the liquid crystal panel 305 of the remote control device 300 (see FIG. 2) is turned off, and only “cleaning” is turned on. Then, the “elapsed” at the bottom of the liquid crystal panel 305 is turned on to display the elapsed cleaning operation time from the elapsed time T3.

  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 motor 53 is reversed to move the nozzle 20 back to the storage position and the cleaning operation is completed.

  At this time, “cleaning” and “elapsed” of the liquid crystal panel 305 of the remote control device 300 are turned off, and the time display is cleared to zero.

  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 position of the nozzle 20 corresponding to the bidet and the flow rate setting 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. Wash the nozzle with water and perform nozzle cleaning.

  Then, the on-off valve 34 is stopped at the elapsed time T5b shown in FIG. 11 to finish the nozzle cleaning. This operation pre-cleans the nozzle 20 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 coincides 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. Then, the hot air heater 43 is energized and the temperature of the heater itself starts to rise. By energizing the warm air heater 43 before operating the air fan 41 in this way, the heater is heated with little heat dissipation, so the heater temperature can be raised at high speed.

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

  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 hot air 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 motor 53 is operated to advance the nozzle 20 to the most advanced position (for example, 150 mm forward), and the second motor 54 is operated to adjust the left-right angle of the nozzle 20 to the right end angle (for example + 50 °). Change the angle.

  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.

  At this point, “Preparing” at the top of the liquid crystal panel 305 of the remote control device 300 (FIG. 2) is turned off, and only “Dry” is turned on. Then, the “remaining” at the bottom of the liquid crystal panel 305 is turned on, and the remaining operation time from the elapsed time T8 to the elapsed time T16 is displayed in a countdown display in units of 1 second. With this remaining time display, the user can grasp the progress of the drying operation.

  Then, in the first step from the elapsed time T8 to the elapsed time T9, the operation direction and the operation speed of the second motor 54 and the first motor 53 of the drive means 52 are controlled, so that the front-rear drive of the nozzle 20 is within a predetermined range ( For example, the left and right angles of the nozzle 20 are slowly driven from the right end angle to the right side predetermined angle (for example, + 50 ° to + 20 °) toward the center angle.

  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. 12 (b), since the ejection of the pressurized air starts from the outside of the ejection range of the washing water, the water droplets spreading and adhering to the right side of the surface to be dried are collected in the central portion direction. Can be blown away.

  In the elapsed time T9 in FIG. 11, 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, FIG.
As shown in C), water droplets spreading and adhering to the left side of the surface to be dried can be blown away while being collected in the direction of the center.

  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. 14, the contact range E of the air jet gradually moves toward the center G while periodically moving in a tangential direction at the tip of the surface F to be dried. Since it moves novelly, a zigzag movement trajectory is drawn as shown in the figure. As a result, water droplets remaining in front of the center portion G of the surface to be dried can be blown away while being collected in the direction of the center portion G.

  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 required time elapses at the elapsed time T16, the air pump 51 is automatically stopped, 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.

  At this time, “remaining” of the liquid crystal panel 305 of the remote control device 300 (FIG. 2) is turned off and “elapsed” is turned on. Then, the time display is cleared to zero, and the operation elapsed time from the elapsed time T16 is displayed. In other words, at this time, it has been operated for the time necessary for drying. Subsequent driving is continued according to the user's preference.

  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, cleaning water is sprayed on the entire nozzle 20, and the entire nozzle 20 can be cleaned. 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 hot air heater 43 is stopped at an elapsed time T18 when the user presses the stop switch 311 of the remote control device 300. At this time, “drying” and “elapsed” of the liquid crystal panel 305 of the remote control device 300 (see FIG. 2) are turned off, and the time display is cleared to zero. Then, by stopping the air fan 41 at the elapsed time T19, the remaining heat of the warm air heater 43 is reduced and the drying operation is completed.
