Description

  The present invention relates to a sanitary washing device having a drying mechanism.

  As a sanitary washing device (including a toilet device, a warm water washing toilet seat, etc.), a device equipped with a drying mechanism for drying a washed portion or the like is known. For example, in Patent Document 1, a movable duct is provided in a flexible duct communicating with a blower that blows warm air so that the movable duct can be moved forward and backward, and a blowout port provided at a front end of the movable duct projects near a portion to be dried by a user. And a sanitary washer having a configuration in which warm air is blown and dried. In this sanitary washer, a detector for detecting that the movable duct has moved to a position corresponding to the site to be dried is provided. When the detector detects that the movable duct has reached a predetermined position, energization of the blower and the heating wire is started, and hot air is ejected from the outlet.

  Specifically, as shown in FIG. 16, in the sanitary washing device disclosed in Patent Document 1, a flexible duct 1004 is provided downstream of a hot air device including a blower 1002 and a heating wire 1003 installed inside a main body 1001. The movable duct 1005 is connected to the downstream of the flexible duct 1004, and a blower outlet 1006 that opens upward is provided at the front end of the movable duct 1005. A magnet 1007 is installed on the side surface of the movable duct 1005, and a reed switch 1008 is installed at a predetermined position of the main body 1001. In a state in which the movable duct 1005 protrudes, the magnet 1007 and the reed switch 1008 are close to each other, so that the reed switch 1008 is “on” by the action of the magnet 1007. Thereby, the air blower 1002 and the heating wire 1003 are energized.

  Patent Document 2 discloses a drying hot air supply device having a configuration in which a hot air nozzle is provided at a front end portion of a blower duct communicating with a blower that blows hot air. This drying hot air supply device is attached to the hot water washing toilet seat, and when not in use, the hot air nozzle is housed in the air duct, and in use, the hot air nozzle is advanced from the air duct by the drive unit. It is configured. Since the front end of the hot air nozzle is provided with a hot air outlet, the hot air outlet protrudes near the user's buttocks when used, and hot air is blown to the buttocks for drying. Become.

  Specifically, as shown in FIG. 17, in the hot air supply apparatus for drying disclosed in Patent Document 2, a blower 1012 and a blower duct 1013 are installed inside the main body 1011, and the front end of the blower duct 1013. A hot air nozzle 1014 is slidably inserted in the part. The hot air nozzle 1014 is configured to be able to advance and retreat by a driving device 1015, and when used, a hot air outlet 1016 provided on the upper surface of the front end of the hot air nozzle 1014 is used from the rear lower surface of the toilet seat 1017 as shown in the figure. It can protrude to the vicinity of the person's buttocks.

  Alternatively, Patent Document 3 discloses a toilet apparatus configured to energize a heater after rotating a blower at the start of operation. As a result, even when the operation of the protector is not in time due to a sudden rise in temperature at the start of the drying operation (heating operation), the rapid rise in temperature of the thermal fuse can be suppressed by blowing air, so this may be blown out by mistake. Absent. Therefore, a temperature fuse having a low fusing temperature can be adopted, and the function of the temperature fuse when an abnormality occurs can be improved. In this toilet apparatus, unlike the techniques disclosed in Patent Documents 1 and 2, there is no description of a hot air nozzle for drying (drying nozzle) that can be advanced and retracted.

JP-A-60-219338 JP 60-215935 A JP 09-279665 A

  As described above, the drying mechanism included in the sanitary washing apparatus has a configuration in which a drying nozzle (corresponding to the “warm air nozzle” in Patent Documents 1 and 2) that blows out hot air for drying advances in use (explanation) For the sake of convenience, it is referred to as a “drying nozzle advancing and retracting type drying mechanism”). However, in these drying nozzle advancing / retracting type drying mechanisms, there is a risk of causing hot air to stay in the drying nozzle when the drying nozzle does not advance during use for some reason.

  For example, it is assumed that the drying nozzle cannot advance due to stool attachment or that a foreign matter such as a thread derived from clothes prevents the drying nozzle from entering. In this case, as disclosed in Patent Document 3, even if the heater is energized after rotating the blower first, if the drying nozzle cannot advance, the hot air for drying stays in the drying nozzle. Therefore, the temperature inside the drying nozzle or the drying mechanism including the drying nozzle may be excessively increased to a predetermined value or more. Such a temperature rise is not preferable for each member or device such as a drying nozzle and a blower provided in the drying mechanism.

  In particular, as exemplified in Patent Document 3, if the sanitary washing device has a heating function or a drying function, a temperature fuse or the like is usually provided as means (overheat protector) for preventing an excessive increase in temperature. However, the stay of hot air in the drying nozzle may cause the thermal fuse to blow.

  If the reason why the drying nozzle cannot advance is due to stool adhesion or foreign matter, the drying nozzle can easily return to a state where advancement is possible if the stool or foreign matter is removed. However, if the thermal fuse is blown out, the power supply to the sanitary washing device is forcibly cut off even though the restoration is easy, and the thermal fuse is restored if it is not replaced with a new one. It becomes impossible to do.

  The present invention has been made to solve such a problem, and the object of the present invention is to prevent the advance of the drying nozzle in a sanitary washing apparatus having a drying nozzle advance / retreat type drying mechanism. An object of the present invention is to effectively avoid the situation in which the temperature inside the drying mechanism rises excessively.

  In order to solve the above-described problems, a sanitary washing device according to the present invention provides a toilet seat, a main body that rotatably supports the toilet seat, a local body of a user who is provided in the main body and is seated on the toilet seat. A cleaning mechanism that enables the cleaning water to be ejected toward the outside, and a drying mechanism that is provided in the main body and that allows hot air to be blown toward the local part. A movable nozzle provided so as to be able to advance, and a fixed nozzle that is located in the main body and can accommodate the movable nozzle therein, and further, the front end portion of the movable nozzle advances from the fixed nozzle. When the front end portion reaches the dry position facing the local portion, the blowout opening that allows the warm air to blow toward the local portion, and the storage position stored in the fixed nozzle, Is hot air in the movable nozzle? A leak opening that allows leakage to the outside of the body, is configured to are provided.

  According to the said structure, even if the movable nozzle which comprises a drying nozzle exists in a storage position by providing a leak opening, it is avoided that a warm air stagnates inside. Therefore, even when the advance of the movable nozzle is hindered, it is possible to effectively avoid a situation in which the temperature inside the drying mechanism rises excessively.

  In the sanitary washing device, specific configurations of the blowout opening and the leak opening are not particularly limited, but the blowout opening is provided on the upper surface of the front end of the movable nozzle, and the leak opening is an end face of the front end. The structure provided as a notch part which followed the said blowing opening in the upper part of can be mentioned as a preferable example.

  According to the said structure, the notch part which followed the blowing opening in the end surface of a front end is provided, and even if a movable nozzle exists in a storage position, the said notch part comprises a leak opening. Therefore, it is not necessary to separately provide an opening independent of the blowout opening, and the configuration of the movable nozzle can be simplified.

  In the sanitary washing device, the drying mechanism further includes a blower, a heater, and an overheat preventer that prevents an excessive increase in the temperature of the drying mechanism, from the upstream side with respect to the direction in which the hot air flows. It is preferable that the air blower, the overheat preventer, and the heater are provided in a positional relationship. The drying mechanism further includes a temperature detector, and the temperature detector is connected to the heater. More preferably, it is provided at a downstream position.

  According to the said structure, not only can the reliability of a drying mechanism be improved further by providing an overheat protector, but the operation of the overheat protector can be performed at a very low frequency by providing a leak opening in the movable nozzle. It can be suppressed. Therefore, the possibility that the operation of the drying mechanism stops can be very low. Further, by providing the temperature detector downstream of the heater, the temperature of the warm air formed by the heater can be appropriately detected, and the operation of the drying mechanism can be made appropriate.

  In the sanitary washing apparatus, it is preferable that a thermostat and a thermal fuse are used as the overheat preventer, and it is more preferable that the thermal fuse is provided at a position closer to the blower than the thermostat.

  According to the said structure, since the overheat protector is provided double, reliability can be made more suitable. In addition, if the temperature fuse, which is a non-recoverable overheat protector, is provided at a position close to the blower, it will operate before the thermostat, which is a returnable overheat protector, as long as the blower is operating normally. There is nothing. Therefore, the operation of the non-reset type thermal fuse can be suppressed, and unnecessary maintenance (inspection or repair) can be suppressed.

  The sanitary washing apparatus further includes a controller and an operation device. When the user operates the operation device to start the operation of the drying mechanism, the controller includes the blower and the heater. It is preferable that the temperature value detected by the temperature detector is acquired and controlled to adjust the output of the heater using the temperature value.

  According to the above configuration, the operation of the drying mechanism is started by the controller when the user operates the operation device, and the output of the heater is adjusted by the temperature detector. Therefore, not only can the drying mechanism be appropriately operated according to the needs of the user, but also the possibility that the temperature inside the drying mechanism rises excessively during normal operation can be eliminated. In addition, the above-described configuration of the movable nozzle can effectively avoid a situation in which the temperature inside the drying mechanism rises excessively even if the advance of the movable nozzle is hindered.

  In the sanitary washing apparatus, the controller outputs the heater so that the temperature of the hot air formed by the blower and the heater does not exceed a preset dry value. It is preferable that it is the structure which performs control which adjusts.

  According to the above configuration, since the temperature of the hot air formed by the drying mechanism is controlled by the controller so as not to exceed the drying value, not only can the hot air in a suitable temperature range be formed in normal operation, In this operation, the possibility that the temperature inside the drying mechanism rises excessively can be eliminated.

  In the sanitary washing device, the drying mechanism further includes an advance / retreat drive mechanism for moving the movable nozzle back and forth, and when the user operates the operation device to start the operation of the drying mechanism, The controller is configured to perform control to start the operation of the blower and the heater before the movable nozzle reaches the drying position after the advancement of the movable nozzle by the advance / retreat driving mechanism is started first. Preferably there is.

  According to the said structure, before a movable nozzle operate | moves previously and the said movable nozzle arrives at a dry position, electricity supply to an air blower and a heater will be started. Therefore, when the movable nozzle reaches the drying position, the temperature of the hot air can be raised to a range suitable for drying. Therefore, for the user, when the hot air starts to blow, the temperature of the hot air is in a comfortable temperature range, so that the possibility that the user feels a cold air is greatly reduced, and the user is inconvenienced. The possibility of giving a pleasant feeling can be sufficiently suppressed.

  Alternatively, in the sanitary washing device, the drying mechanism further includes an advance / retreat drive mechanism for moving the movable nozzle forward and backward, and when the user operates the operation device to start the operation of the drying mechanism, When the controller detects that the temperature of the hot air has reached the dry value after starting the operation of the blower and the heater first, the controller drives the advance / retreat mechanism. The control for starting the advance of the movable nozzle may be configured.

  According to the said structure, after the state which can raise the temperature of a warm air to the temperature range suitable for drying is established, the advance operation of a movable nozzle will be started. Therefore, it is possible to substantially prevent the cool air from hitting the user's local area and the like, and the possibility of giving the user discomfort can be sufficiently suppressed.

  In the sanitary washing apparatus, in addition to any of the controls described above, the controller outputs the heater output immediately after the start of the operation of the heater, and the standard output for maintaining the dry value of the hot air. And when the temperature of the hot air detected by the temperature detector reaches an adjustment value set as a value lower than the dry value, the output of the heater Is more preferable when the control is performed to reduce the start output value to the standard output value.

  According to the above configuration, the temperature rising rate of the hot air is controlled to be relatively high for a certain period after the operation of the heater is started, and when the temperature approaches the dry value that is the set temperature, the temperature rises. Control to reduce the temperature rate. This effectively suppresses the possibility that the temperature of the hot air overshoots the dry value, and therefore the temperature of the hot air can be raised to the dry value in a short time and the temperature of the hot air is adjusted more appropriately. It becomes possible.

  In the sanitary washing apparatus, the fixed nozzle is provided in the main body in an inclined state so that a front end portion thereof is downward, and the temperature detector is disposed at the rear end portion of the fixed nozzle. It is preferable that the movable nozzle is provided at a position exposed inside the movable nozzle in a state where the movable nozzle is accommodated therein.

  According to the said structure, a temperature detector will be located in the uppermost part of the drying nozzle (a fixed nozzle and a movable nozzle) provided in inclination. Therefore, even if an aqueous liquid such as washing water or urine flows into the fixed nozzle, the possibility that these aqueous liquids affect the temperature detector can be effectively avoided. Further, the temperature detector is exposed in the hot air passage regardless of whether the movable nozzle is in the storage position or the drying position. Therefore, the temperature of the warm air formed by the heater can be detected more appropriately, and the operation of the drying mechanism can be made more appropriate.

  In the sanitary washing apparatus, the lower inner surface of the rear end portion of the fixed nozzle is a flat surface having an inclination angle smaller than the inclination angle of the fixed nozzle itself, and the temperature detector is disposed on the flat surface. Preferably, the flat surface is provided with a protruding portion protruding upward, and the temperature detector is more preferably located on the protruding portion.

  According to the above configuration, the temperature detector is located downstream of the heater, and the flat surface is the lower inner surface of the rear end portion of the fixed nozzle. Therefore, the position where the temperature detector is provided is downstream of the heater. And it corresponds to the connecting portion between the inclined fixed nozzle and the heater. Therefore, even if a special part for providing the temperature detector in the drying mechanism is not formed, the temperature sensor can be provided only by providing a flat surface on the rear side of the fixed nozzle. Increase in size can be suppressed. Further, since the flat surface is inclined more gently than the inclination angle of the fixed nozzle, even if the aqueous liquid flows into the fixed nozzle vigorously, the temperature detector exposed in the fixed nozzle Since it will be located below, the possibility that the aqueous liquid may be applied to the temperature detector can be effectively suppressed. In addition, if the temperature detector is provided on the protrusion, it is possible to effectively suppress the possibility that the aqueous liquid that has flowed down contacts the temperature detector.

  In the sanitary washing device, a rear end portion of the movable nozzle is cut forward so that the temperature detector can be exposed when the movable nozzle is housed in the fixed nozzle. It is preferable that a cut portion is provided.

  According to the above configuration, in a state where the movable nozzle is accommodated in the fixed nozzle (accommodated position), the temperature detector provided on the flat surface can be exposed in the movable nozzle.

  In the sanitary washing apparatus, the temperature detector is provided between a lower outer surface of the movable nozzle and a lower inner surface of the fixed nozzle in a state where the movable nozzle is housed in the fixed nozzle. It is preferable that a groove-like gap reaching from the position to the rear end of the fixed nozzle is provided.

  According to the above configuration, since the groove-shaped gap is provided on the inner surface of the fixed nozzle, the contact area between the fixed nozzle and the movable nozzle is reduced, and the sliding resistance of the movable nozzle within the fixed nozzle is reduced. be able to. Further, even if an aqueous liquid enters the fixed nozzle, it tends to flow through the groove-like gap and be discharged out of the fixed nozzle.

  As described above, according to the present invention, in the sanitary washing apparatus including the drying nozzle advance / retreat type drying mechanism, the temperature inside the drying mechanism rises excessively even when the advancement of the drying nozzle is hindered. There is an effect that the situation can be effectively avoided.

In the state where the movable nozzle 703 protrudes completely, the air outlet 703e of the movable nozzle 703 is provided at a position that is not blocked by the nozzle shutter 203, so that hot air is blown out from the air outlet 703e toward the local area. Become.

  The reason why the nozzle shutter 203 is opened by the bidet nozzle 103 b during drying is that the drying unit 700 is provided at a position off the center of the main body 200. In other words, the nozzle shutter 203 is provided in the center of the lower part of the front side of the main body 200, but if the drying unit 700 is provided at a biased position, the movable nozzle 703 is inevitably located on one side of the nozzle shutter 203. It will be biased. Therefore, since it is difficult to reliably open the nozzle shutter 203 with the movable nozzle 703 itself, the bidet nozzle 103b located at the center of the main body 200 is used.

  Of course, the nozzle shutter 203 may be opened by the butt cleaning nozzle 103a, or the nozzle shutter 203 may be configured to be opened by separately providing a shutter opening / closing drive mechanism such as a stepping motor. A specific position of the drying unit 700 in the main body 200 will be described later.

  As shown in FIG. 4, a control unit 204 is provided inside the main body 200. The control unit 204 controls the operation of each part of the sanitary washing device 100 based on signals transmitted from the remote controller 500, the human body detection sensor 201, and the seating sensor 202. In the present embodiment, the control unit 204 includes a main control unit 204a and sub control units 204b and 204c.

  An example of the control by the control unit 204 will be described. For example, when there is no user in the toilet room, the control unit 204 stops energization of the toilet seat heater in the toilet seat 400 or keeps the temperature low at about 20 ° C. ing. When the user enters the toilet room, the control unit 204 receives a signal from the human body detection sensor 201 and energizes the toilet seat heater. The toilet seat heater is a heater with a very high output of about 800 W, and the seating surface of the toilet seat 400 is placed at 40 ° C. for about 6 to 10 seconds from when the user enters the toilet room until the user sits on the toilet seat 400. Warm to a suitable temperature. After the toilet seat 400 reaches an appropriate temperature, the control unit 204 reduces the energization of the toilet seat heater to a low wattage of about 50 W to maintain the appropriate temperature. When the user leaves the toilet room, the control unit 204 stops energizing the toilet seat heater or keeps the temperature at a low temperature of about 20 ° C. Thus, the sanitary washing device 100 according to the present embodiment is controlled by the control unit 204 so that the power when there is no user in the toilet room can be significantly reduced.

  Further, the toilet seat toilet lid opening / closing unit (not shown) automatically opens and closes the toilet lid 300 and the toilet seat 400 as described above, and by rotating the rotation shafts of the toilet lid 300 and the toilet seat 400 electrically, It is configured as a toilet seat toilet lid rotating mechanism that rotates these.

[Relationship of functional units]
Next, in the sanitary washing apparatus 100 having the above-described configuration, the positional relationship among the functional units and the like in the main body 200 will be specifically described with reference to FIGS.

  As described above, the main body 200 includes the water supply unit 101, the heat exchanger 102, the cleaning nozzle unit 103, the deodorizing unit 105, the drying unit 700, the control unit 204, the toilet seat toilet lid opening / closing unit, and the like as functional units. It has been.

  Among them, the cleaning nozzle unit 103 is one of the most important functional units in the sanitary cleaning device 100, and the butt cleaning nozzle 103a and the bidet nozzle 103b are installed in the main body in order to clean the local part of the user seated on the toilet seat 400. It is necessary to protrude out of 200. Further, since the buttocks cleaning nozzle 103a and the bidet nozzle 103b have such a length that they reach the local area, the buttocks cleaning nozzle 103a and the bidet nozzle 103b can be prevented from increasing in size inside the main body 200. The bidet nozzle 103b is inclined. Therefore, basically, the cleaning nozzle unit 103 is disposed at the center of the main body 200. As a result, the nozzle outlet 103c is positioned at the center of the front lower portion of the main body 200.

  Here, as described above, since the air pump 104 is for mixing air into the cleaning water, the air pump 104 is preferably disposed in the vicinity of the cleaning nozzle unit 103. In the present embodiment, as shown in FIGS. 2 to 4, the cleaning nozzle unit 103 is provided on the right side (left side in the drawing).

  Further, since the water supply unit 101 is a functional unit for supplying cleaning water from the outside to the inside of the main body 200, the water supply unit 101 must be disposed at either the left or right end of the main body 200. In the present embodiment, the water supply unit 101 is provided at the right end (left side in the drawing), but may be the left end.

  Further, since the toilet seat toilet lid opening / closing unit is for opening and closing the toilet lid 300 and the toilet seat 400 that are rotatably provided above the main body 200, the toilet seat toilet lid opening / closing unit is preferably provided on the upper side of the main body 200. In the present embodiment, it is provided in a space on the upper right side between the water supply unit 101 and the cleaning nozzle unit 103 (space on the upper left side in the drawing).

  Moreover, it is preferable to provide the deodorizing unit 105 in the center part of the main body 200 if possible from a viewpoint of removing the defecation odor in the toilet bowl 600. FIG. However, as described above, it is necessary to preferentially provide the cleaning nozzle unit 103 in the central portion, and the position where the suction port 105a for sucking the defecation odor in the toilet 600 is as close as possible to the central portion in the lower front side of the main body 200 If it can be provided, there is almost no condition for limiting the position of the deodorizing unit 105 itself. Therefore, in this embodiment, the deodorizing unit 105 is provided at the left end portion (right side in the drawing) of the main body 200, and only the suction port 105a is provided from the center portion by the duct.

  Here, the dimensions of the heat exchanger 102 and the control unit 204 are relatively small compared to other functional units. Therefore, in consideration of the shape of the main body 200, another functional unit to be prioritized can be arranged and then appropriately arranged in the remaining space. For example, in the present embodiment, the heat exchanger 102 is provided at the left rear part (the rear right part in the drawing) of the main body 200, and the drying unit 700 is located in the front. Further, as shown in FIG. 4, the control unit 204 is disposed in a space above the cleaning nozzle unit 103, the drying unit 700, and the heat exchanger 102.

  In the present embodiment, the sanitary washing apparatus 100 includes the drying unit 700. However, since the drying unit 700 needs to blow warm air to the local part of the user, it is also located at the center of the main body 200. It is preferable. However, since it is necessary to preferentially provide the cleaning nozzle unit 103 in the central portion as described above, basically, the cleaning nozzle unit 103 is provided adjacent to the cleaning nozzle unit 103 at a position from the central portion. In the present embodiment, the main body 200 is provided on the left side of the central portion (on the right side of the center in the drawing).

  As described above, in the deodorizing unit 105, since the position of the suction port 105a only needs to be close to the central portion, the priority order of the functional units provided in the central portion of the main body 200 is from the highest order to the cleaning nozzle unit 103, It becomes the drying unit 700 and the deodorizing unit 105.

  Thus, although the drying unit 700 is close to the central portion of the main body 200, it is unavoidable to be provided at a position close to the left and right from the central portion. Therefore, the movable nozzle 703 provided in the drying unit 700 protrudes from a storage position (described later) located on the side of the cleaning nozzle unit 103 toward a drying position (described later) that is inclined toward the lower front side of the central portion. It is configured as follows. Moreover, the blower outlet 703e provided in the movable nozzle 703 also has an original shape that can blow out warm air toward the center. This point will be described later.

The specific configurations of the water supply unit 101, the heat exchanger 102, the cleaning nozzle unit 103, the deodorizing unit 105, the drying unit 700, the control unit 204, the toilet seat toilet lid opening / closing unit and the like are not particularly limited, and the drying unit 700 Except for a unique configuration (described later) such as the movable nozzle 703 included in the above, various known configurations are preferably used.
The specific configuration of these units is not particularly limited [Overall configuration of drying unit]
Next, a specific configuration of the drying unit 700 in the present embodiment will be specifically described with reference to FIGS. FIG. 5 is a perspective view illustrating an example of an external configuration of the drying unit 700, and FIGS. 6 and 7 are schematic cross-sectional views of the drying unit 700. 6 shows a state where the movable nozzle 703 is in the storage position, and FIG. 7 shows a state where the movable nozzle 703 is in the drying position. 8 is a cross-sectional view taken along line AA of the drying unit 700 shown in FIG. FIG. 9 is a perspective view showing an example of the configuration of the heater unit 708 provided in the drying unit 700, and is a view of the heater unit 708 as viewed from the rear.

  4 to 6, the drying unit 700 includes a case 701, a fixed nozzle 702, a movable nozzle 703, a drive motor 704, a gear mechanism 705, a heater unit 708, a fan motor 709, a thermistor 710, and the like. .

  As shown in FIG. 5, the case 701 serving as the exterior of the drying unit 700 has a configuration in which an upper case 701 a and a lower case 701 b formed of, for example, a flame retardant resin are coupled to each other in the vertical direction. Yes.

  As shown in FIGS. 6 and 7, the case 701 has a configuration in which a substantially tunnel-like cavity is formed inside, and an opening serving as an air flow inlet / outlet is provided at the front and rear ends. Of these, the air flow inlet side is the rear end opening 701c, and the air flow outlet side is the front end opening 701d. Further, the vicinity of the front end opening 701d is a front end portion of the case 701 and a fixed nozzle 702.

  Inside the case 701, a fan motor 709, a heater unit 708, a thermistor 710, and a movable nozzle 703 are provided in order from the rear end opening 701c toward the front end opening 701d. The rear end portion of the case 701 in the vicinity of the rear end opening 701c has a larger inner diameter than the front end portion (fixed nozzle 702) in order to arrange the heater unit 708 and the fan motor 709. Therefore, the case 701 converges so that the cross-sectional area decreases from the rear end opening 701c toward the front, and the front end is a cylindrical fixed nozzle 702 having a constant cross-sectional area. Can be considered funnel-shaped.

  The fan motor 709 is a blower for forming an air flow in the tunnel-shaped cavity of the case 701. Air is introduced into the case 701 from the rear end opening 701c by the operation of the fan motor 709, and is directed toward the front end opening 701d. The air flow is blown. Since the heater unit 708 is provided on the front side of the fan motor 709, the air flow is heated by the heater unit 708, so that warm air is formed. That is, the heater unit 708 is a heater that heats the air flow.

  The formed warm air passes through the thermistor 710 and the movable nozzle 703, and is blown out (or blown out) from the air outlet 703 e provided at the tip of the movable nozzle 703. Here, since the case 701 has a funnel shape, the air flow introduced from the rear end opening 701c is concentrated until it passes through the movable nozzle 703, thereby increasing the speed. Therefore, the warm air blown from the outlet 703e is energized and applied to the local area. The thermistor 710 is a temperature detector and outputs temperature information as a signal to the control unit 204 described above. The control unit 204 controls the hot air temperature in the drying unit 700 based on the temperature detected by the thermistor 710.

  If the rear end portion of the case 701 is used as a reference, the front end portion, that is, the fixed nozzle 702 is inclined downward so that the front portion is lowered from the rear portion. This is because when the drying unit 700 is provided in the main body 200, the front end opening 701 d is positioned at the lower front side of the main body 200. In the present embodiment, the fixed nozzle 702 has a cylindrical shape with a substantially rectangular cross section, and an inner surface below the inclined surface 702a. Therefore, the lower wall portion of the fixed nozzle 702 that forms the inclined surface 702a can be regarded as an inclined portion.

  As shown in FIG. 6, the fixed nozzle 702 can accommodate a movable nozzle 703, and this position is referred to as a storage position of the movable nozzle 703. Further, as will be described later, the movable nozzle 703 is slidably provided inside the fixed nozzle 702, and can advance from the front end opening 701d to the outside of the fixed nozzle 702 as shown in FIG. This advanced position corresponds to the position where the front end of the movable nozzle 703 faces the local part of the user seated on the toilet seat 400 in the toilet 600, and is referred to as the dry position of the movable nozzle 703. In this embodiment, the fixed nozzle 702 and the movable nozzle 703 constitute a drying nozzle.

  The uppermost portion of the inclined surface 702a of the fixed nozzle 702, that is, the portion adjacent to the position where the heater unit 708 is provided on the rear end side of the fixed nozzle 702 is connected to the inclined surface 702a, and from the inclined surface 702a. Also, a flat surface 702c having a gentle slope is provided. That is, the fixed nozzle 702 is provided in the main body 200 in a state where the fixed nozzle 702 is inclined so that the front end portion is downward. The lower inner surface of the rear end portion of the fixed nozzle 702 is a flat surface 702c having an inclination angle smaller than the inclination angle of the fixed nozzle 702 itself (that is, the inclination angle of the inclined surface 702a). The lower wall portion on the rear end side of the fixed nozzle 702 forming the flat surface 702c can be regarded as a flat portion.

  In the present embodiment, the flat surface 702c is provided with a substantially cylindrical protruding portion 702d that protrudes upward at a position substantially at the center thereof. A thermistor 710 is attached to the approximate center of the protrusion 702d. Normally, the temperature measuring unit of the thermistor 710 is formed of a metal shell, but by adopting this configuration, even if an aqueous liquid such as washing water or urine flows into the fixed nozzle 702, the temperature measuring unit is flat. The possibility that the aqueous liquid that has flowed down to the surface 702c contacts the thermistor 710 can be effectively avoided.

  Further, since the thermistor 710 is a temperature detector, it needs to be provided at a position downstream of the heater unit 708 which is a heater. Here, the flat surface 702 c is downstream of the heater unit 708 and corresponds to a connecting portion between the inclined fixed nozzle 702 and the heater unit 708. Even if a special portion for providing the thermistor 710 is not formed, the thermistor 710 can be provided only by setting the rear side of the inclined surface 702a to the flat surface 702c. it can. Further, since the flat surface 702c is inclined more gently than the inclined surface 702a, even if the aqueous liquid flows into the fixed nozzle 702 vigorously, the thermistor 710 exposed in the fixed nozzle 702 is in the inflow direction of the aqueous liquid. Since it will be located below, the possibility that the aqueous liquid may be applied to the thermistor 710 can be effectively suppressed. As will be described later, the movable nozzle 703 is configured such that its rear end does not contact the thermistor 710 when it is in the storage position.

  In this embodiment, the air outlet 703e provided at the front end of the movable nozzle 703 will be described in detail later. In addition to opening upward, a plurality of air outlets 703e are continuously formed. A notch is provided. Therefore, the aqueous liquid may enter the movable nozzle 703 during use.

  Further, since the sanitary washing device 100 is contaminated with urine and feces during use, it is necessary to wash the protruding members (butt washing nozzle 103a, bidet nozzle 103b, movable nozzle 703) and their surroundings for cleaning. Among the projecting members, the movable nozzle 703 has a relatively large opening area of the air outlet 703e for the purpose of blowing air, and has a notch portion, so that the opening area is further increased. Further, the cross-sectional area of the movable nozzle 703 is wider than that of the buttocks cleaning nozzle 103a. Therefore, the cleaning water at the time of cleaning may pass through the movable nozzle 703 and the fixed nozzle 702 and reach the vicinity of the thermistor 710, the heater unit 708, or the fan motor 709.

  Among these, if an aqueous liquid adheres to the thermistor 710, an error occurs in the detected temperature, and there is a possibility that hot air having a high temperature exceeding the set temperature is blown out from the outlet 703e. In addition, when an aqueous liquid adheres to the heater unit 708 or the fan motor 709, there is a risk of causing rust or failure.

  On the other hand, in the present embodiment, by forming the flat surface 702c, it becomes difficult for the aqueous liquid to enter the rear end side of the drying unit 700. Therefore, the possibility that an error may occur in the temperature detected by the thermistor 710 can be suppressed, and the influence on the heater unit 708 or the fan motor 709 can be avoided. In particular, with respect to the thermistor 710, by providing a projection 702d on the flat surface 702c and disposing the thermistor 710 on the projection 702d, contact with an aqueous liquid can be more preferably avoided.

  In this embodiment, a flat surface 702c connected to the inclined surface 702a is provided at the rear end portion of the fixed nozzle 702. However, the present invention is not limited to this, and at least a temperature detector such as the thermistor 710 is provided. The rear end portion of the fixed nozzle 702 may be provided at a position exposed to the inside of the movable nozzle 703 in a state where the movable nozzle 703 is stored in the fixed nozzle 702 (a state in the storage position). As a result, the temperature detector is positioned at the uppermost position of the inclined surface 702a, so that the influence of the aqueous liquid can be effectively avoided with this configuration alone. Of course, the thermistor 710 is exposed to the hot air passage regardless of whether the movable nozzle 703 is in the storage position or in the drying position, and thus detects the temperature of the hot air more appropriately. The operation of the drying unit 700 can be controlled more appropriately.

  In the present embodiment, as shown in FIG. 8, it is more preferable that a groove-like gap 702e is provided between the fixed nozzle 702 and the movable nozzle 703. Specifically, as shown in the cross-sectional view of FIG. 8, on the inclined surface 702a, for example, sliding surface ribs 702b having a height of about 0.5 mm are linearly provided along the inclined direction, and thereby movable. A groove-like gap 702e is formed between the nozzle 703 and the fixed nozzle 702. Due to the presence of the groove-like gap 702e, the contact area between the fixed nozzle 702 and the movable nozzle 703 is reduced, and the sliding resistance of the movable nozzle 703 within the fixed nozzle 702 can be reduced. Further, the aqueous liquid that has entered the fixed nozzle 702 flows through the groove-like gap 702e and is easily discharged from the front end opening 701d.

  The specific configuration of the groove-like gap 702e is not limited to this, and the sliding surface rib 702b is not provided on the inclined surface 702a, but the outer surface below the movable nozzle 703 (in this embodiment, a substantially flat back surface). 703m, see FIG. 11), or similar ribs may be provided on both the inclined surface 702a and the back surface 703m. Further, it may be realized by a protrusion other than the sliding surface rib 702b, or a groove may be engraved on the inclined surface 702a, or conversely, a groove may be engraved on the back surface 703m of the movable nozzle 703. . That is, in the present invention, in a state where the movable nozzle 703 is accommodated in the fixed nozzle 702, the space between the lower outer surface (back surface) of the movable nozzle 703 and the lower inner surface (inclined surface 702a) of the fixed nozzle 702 is It is only necessary to provide a groove-like gap that reaches the rear end portion (front end opening 701d) of the fixed nozzle 702 from the position where the temperature detector such as the thermistor 710 is provided.

  Further, the specific configuration of the drying unit 700 in the present embodiment is not limited to the configuration described above except for the basic configuration of the movable nozzle 703 to be described later. For example, the drying unit 700 is not limited to a configuration including the fan motor 709, the heater unit 708, and the thermistor 710. For example, another fan may be used instead of the fan motor 709, or another temperature may be used instead of the thermistor 710. A detector may be used.

  Here, in the present embodiment, it is more preferable that the heater unit 708 is integrally provided with an overheat protector. The overheat preventer is a means for avoiding or preventing the temperature at which the air flow is heated from being excessively raised (temperature rise prevention means), and may be provided as an independent member separate from the heater unit 708. However, the drying unit 700 can be further downsized by being integrated with the heater unit 708.

  As shown in FIG. 9, the heater unit 708 in the present embodiment is provided with a spiral heater wire 708a of about 340 W in a cover mica 708d serving as an outer shell. In other words, the cover mica 708d functions as a housing for the heater unit 708. Further, a thermal fuse 708b operating at 113 ° C. and a thermostat 708c operating at 94 ° C. are attached in the cover mica 708d.

  The heater wire 708a is a substantial heater (heating means) that heats the air flow. As described above, the heater wire 708a is attached to the cover mica 708d together with the temperature fuse 708b and the thermostat 708c. It is substantially integrated. Therefore, in the present embodiment, the entire heater unit 708 is defined as a heater in a broad sense, and the heater wire 708a is defined as a heater in a narrow sense.

  The heater wire 708a formed in a spiral shape is provided in the cover mica 708d at a position near the outer periphery thereof, and a thermal fuse 708b and a thermal fuse 708b are connected to the inside of the spiral of the heater wire 708a via a board-like mounting member 708e. A thermostat 708c is provided. As shown in FIG. 9, the thermal fuse 708b is arranged behind the cover mica 708d, that is, at a position close to the fan motor 709, and a thermostat 708c is arranged in front of the cover mica 708d. The heater wire 708a, the thermal fuse 708b, and the thermostat 708c are electrically connected in series.

  The thermal fuse 708b and the thermostat 708c are both overheat protectors and detect whether or not the temperature inside the cover mica 708d is excessively increased. The thermostat 708c is a return type overheat preventer, while the thermal fuse 708b is a non-reset type overheat preventer. As described above, if the thermostat 708c and the thermal fuse 708b are used in combination as the overheat preventer, the overheat preventer is provided in duplicate, so that the reliability can be further improved.

  For example, if the fan motor 709 breaks down and becomes locked, the internal temperature of the heater unit 708 rises excessively because no air flow is formed. At this time, first, as a first step, the thermostat 708c, which is a return type overheat preventer, operates first to cut off the energization to the heater wire 708a. Further, if the thermostat 708c does not operate due to a failure or the like, as a second step, the temperature fuse 708b, which is a non-reset type overheat preventer, is blown to cut off the energization to the heater wire 708a.

  In this way, by providing the thermal fuse 708b closer to the fan motor 709 than the thermostat 708c, not only can the reliability be improved, but the return thermostat 708c can be operated first. The operation of the non-returnable thermal fuse 708b can be suppressed. In other words, if the temperature fuse 708b is provided at a position close to the fan motor 709, the temperature of the non-returnable temperature fuse 708b is kept lower than the temperature of the thermostat 708c as long as the fan motor 709 operates normally. . Therefore, the operation of the non-reset type thermal fuse 708b can be suppressed, and unnecessary maintenance (inspection or repair) can be suppressed.

  In the present embodiment, of course, the heater unit 708 is not limited to the above-described configuration, and other configurations can be adopted. That is, in the present invention, the drying unit 700 includes a blower, a heater, and an overheat preventer, and is located in the order of the blower, the overheat preventer, and the heater from the upstream side with respect to the direction in which the hot air flows. What is necessary is just to be provided by the relationship.

[Configuration of movable nozzle]
Next, an example of a specific configuration of the movable nozzle 703 provided in the drying unit 700 will be described in detail with reference to FIGS. 10 and 11 in addition to FIGS. 10 and 11 are perspective views showing an example of the configuration of the movable nozzle 703. FIG. 10 is a perspective view from above, and FIG. 11 is a perspective view from below. 12 and 13 are perspective views showing modifications of the drying unit 700. FIG. 12 shows a state where the movable nozzle 703 is in the storage position, and FIG. 13 shows the movable nozzle 703 in the drying position. Indicates the state.

  As shown in FIGS. 10 and 11, the movable nozzle 703 has a substantially rectangular parallelepiped cylindrical shape corresponding to the shape of the fixed nozzle 702. The movable nozzle 703 is molded of a flame retardant resin as in the case 701. The inner surface of the lower wall portion is the bottom surface 703a, the outer surface of the lower wall portion is the rear surface 703m, the outer surface of the upper wall portion is the top surface 703c, and the both side wall portions. The outer surface is a side surface 703b, and the front end side is closed to form a front end surface 703d.

  Among these, as shown in the cross-sectional view of FIG. 8, the bottom surface 703a is curved so that the right side (the right side in the state provided in the main body 200, the upper side in the drawing) is lower than the left side (the lower side in the drawing). It is formed as a surface. Further, as shown in FIGS. 5 and 10, the front end of the top surface 703 c is provided with a substantially trapezoidal air outlet 703 e as an outlet opening for blowing out warm air. Further, as shown in FIGS. 6, 7, and 11, a curved surface portion 703f is formed at the front end portion of the bottom surface 703a connected to the air outlet 703e so that the inner surface is formed as a curved surface. In addition, as shown in FIG. 11, a drain hole 703g is provided on the right side of the curved surface portion 703f.

  As described above, since the bottom surface 703a is an inclined curved surface, the warm air flowing in the movable nozzle 703 can be blown out toward the center (close to the cleaning nozzle unit 103). In addition, by providing the curved surface portion 703f, it is possible to smoothly blow out the warm air blown from the rear end toward the front outlet 703e when it is provided in the main body 200, obliquely upward, The possibility that the amount of warm air hitting the local area is reduced can be suppressed. Further, by having the bottom surface 703a and the curved surface portion 703f having the above-described configuration, even if the aqueous liquid enters the movable nozzle 703, the aqueous liquid gathers in the vicinity of the drain hole 703g at the front end and is easily discharged from the drain hole 703g. Will be.

  Here, the shape of the air outlet 703e is not particularly limited, but as shown in FIG. 10, it is substantially trapezoidal, the right side corresponding to the upper base of the trapezoid is short, and the left side corresponding to the lower base is short. The shape is preferably long, and more preferably, the above-described curved surface portion 703f is provided on the bottom surface 703a facing the air outlet 703e.

  The local area of the user seated on the toilet seat 400 is an area that is forward when viewed from the center of the main body 200. Therefore, as described above, the cleaning nozzle unit 103 that is a functional unit for cleaning a local portion is preferably disposed in the center of the main body 200. On the other hand, since the drying unit 700 is also a functional unit that applies hot air to the local area, the drying unit 700 is preferably disposed in the center, but the priority of the function is relatively small compared to the cleaning nozzle unit 103. Therefore, in the present embodiment, the drying unit 700 is disposed on the left side of the cleaning nozzle unit 103 (the right side in FIGS. 2 to 4). Therefore, the direction of the warm air blown from the movable nozzle 703 is set in a direction toward the right side (the left side in FIGS. 2 to 5) closer to the center.

  In this Embodiment, the blowing direction of warm air can be converged to the right side by making the shape of the blower outlet 703e into a trapezoidal shape as shown in FIG. Therefore, not only can the directivity of the hot air to the local area be improved, but also the air passage width narrows in the process of the hot air moving from the left side to the right side in the air outlet 703e, thereby increasing the speed of the hot air. Become. Therefore, the directivity can be increased toward the local area of the warm air, and the directivity can be further increased. Furthermore, if the curved surface portion 703f is provided, the warm air flowing out from the upper portion of the main body 200 toward the front lower portion can be redirected to the upper right side of the air outlet 703e by the curved surface portion 703f. The sex can be further enhanced.

  In addition, in the present embodiment, it is more preferable that a front side cutout portion 703i is provided in a portion corresponding to the right side of the air outlet 703e. That is, in the blower outlet 703e, the part which becomes the front end of the side surface 703b on the right side (the side facing the cleaning nozzle unit 103) is a front side cutout portion 703i whose upper end is lower than the top surface 703c. Thereby, since the upper part of the side wall part of the movable nozzle 703 which becomes the upper right side of the blower outlet 703e is removed, it is suppressed that the blowing of warm air is prevented by the side wall part. That is, by providing the front side cutout portion 703i, the warm air converged toward the central portion by the blowout port 703e, the bottom surface 703a, and the curved surface portion 703f can be blown out well without being hindered. Therefore, the front side notch part 703i has the function to prescribe | regulate the ventilation direction of warm air with the shape of the blower outlet 703e.

  In addition, the bottom surface 703a is a curved surface inclined so that the right side faces downward as described above, and if the curved surface portion 703f described above is provided, the warm air blown from the outlet 703e is provided. Increases the directivity toward the upper right side. Therefore, the air volume of the warm air blown to the local part can be made sufficient. As shown in FIGS. 3 to 5, the protruding direction of the movable nozzle 703 does not protrude in a substantially vertical direction toward the front of the main body 200 but protrudes to the right so as to be closer to the center. It is preferable to do. Thereby, since the effect | action by each structure of the movable nozzle 703 mentioned above can further be heightened, a warm air can be favorably directed toward the local part of the user corresponding to the center part of the toilet seat 400. FIG.

  Here, at the front end of the movable nozzle 703, not only the outlet 703e (outlet opening) that allows the hot air to be blown out toward the local area when in the dry position, but also the hot air when in the storage position. It has a leakage opening that allows leakage from within the movable nozzle 703.

  Specifically, an air outlet 703e is provided on the upper surface of the front end of the movable nozzle 703, but a front end notch 703j as a leakage opening is provided on the upper end surface (front end surface 703d) of the front end. . That is, in the movable nozzle 703, the upper part of the front end surface 703d at the outlet 703e is a front end notch 703j whose upper end is lower than the top surface 703c. If the front end notch 703j is provided, a leakage opening is formed by the front end notch 703j when the movable nozzle 703 is in the storage position. Therefore, the inside and outside of the movable nozzle 703 at the storage position can be vented.

  Usually, since the movable nozzle 703 of the drying unit 700 protrudes to the drying position when in use, the air outlet 703e is sufficiently open, and therefore the hot air does not stagnate. However, since the movable nozzle 703 is accommodated in the fixed nozzle 702 when not in use, the outlet 703e is blocked unless the front end notch 703j is provided. If the movable nozzle 703 is in the storage position when the heater unit 708 and the fan motor 709 are operated to start sending warm air, the warm air is stagnated in the movable nozzle 703 and the internal temperature is excessive. May rise. In this case, the fan motor 709 may be greatly affected by heat, and the case 701 (including the fixed nozzle 702) and the movable nozzle 703 are also affected by heat even though the fan motor 709 is molded from a flame-retardant resin. There is a risk of being greatly affected.

  On the other hand, in the present embodiment, by providing the front end notch 703j, it is possible to form a leak opening that communicates the inside and outside of the movable nozzle 703 even when the movable nozzle 703 is in the storage position. Therefore, it is avoided that the warm air stays inside. In this state, the thermal fuse 708b and the thermostat 708c, which are overheat protectors, do not operate. Thereby, since the operation of the overheat protector is suppressed to a very low frequency, the possibility of the operation of the drying unit 700 being stopped can be very low.

  Further, the front end notch portion 703j is provided as a notch portion that is continuous with the air outlet 703e, which is the air outlet, on the front end surface 703d of the movable nozzle 703. Therefore, when the movable nozzle 703 is manufactured, it is not necessary to separately provide an opening independent from the air outlet 703e, the configuration of the movable nozzle 703 can be simplified, and the manufacturing process of the movable nozzle 703 can be avoided. Can do.

  Furthermore, the front side notch 703i described above can exhibit not only a function of defining the direction of warm air blowing but also a function as a leakage opening together with the front end notch 703j. For example, if the movable nozzle 703 is in the storage position, most of the front side notch 703 i is basically covered by the fixed nozzle 702. However, as shown in FIG. 10, the front side cutout 703 i and the front end cutout 703 j have different cutouts with respect to the top surface 703 c, but are continuous with each other. Will be formed. Therefore, although the front side notch 703i has a small function, it can also function as a leakage opening. Moreover, it is also possible to simplify the structure of the movable nozzle 703 by being comprised as an integral notch part.

  In addition, in the present embodiment, as shown in FIGS. 12 and 13, a front side opening 702 f can be provided at the upper right corner of the front end of the fixed nozzle 702. With this configuration, as shown in FIG. 14, even if the movable nozzle 703 is in the storage position, the position of the front side opening 702f and the position of the front side notch 703i coincide with each other. A leakage opening with a can be formed. In this case, the front end notch 703j may not be provided. As shown in FIG. 15, when the movable nozzle 703 advances to the drying position, the front side opening 702f is closed by the side surface 703b of the movable nozzle 703. Therefore, warm air does not leak from the front side opening 702f, and the warm air can be blown out satisfactorily.

  Note that the outlet 703e, which is a blowout opening and a means for defining the blowing direction of warm air, a front end cutout portion 703j constituting the leakage opening, and a means for regulating the blowing direction of hot air and the leakage opening are also provided. The specific configuration of a certain front side notch 703i is not particularly limited.

  For example, in the present embodiment, the opening area of the leakage opening formed by the front end notch 703j and the inner peripheral surface of the fixed nozzle 702 may be smaller than the opening area of the outlet 703e, and preferably 30% or less. That's fine. If the opening area of the leakage opening is 30% or less, the front end notch portion 703j is prevented from becoming excessively large. Therefore, the front end surface 703d (front end wall portion) of the movable nozzle 703 is placed at the center of the hot air. The area can be controlled to be close to the part.

  Further, since the front side notch 703i gives priority to the function of defining the blowing direction, as shown in FIG. 10, the degree of the notch based on the top surface 703c is larger than the front end notch 703j. However, depending on the configuration of the fixed nozzle 702, the movable nozzle 703, the air outlet 703e, etc., they may be cut out equally or the front end cutout portion 703j may be cut out larger. . Alternatively, in the present embodiment, the front side notch portion 703i and the front end notch portion 703j continuously form an integral notch portion even though the degree of the notch is different. The notch part 703i and the front end notch part 703j may each be configured as a single notch part.

  In addition, in the present embodiment, at least the front end notch 703j and the inner peripheral surface of the fixed nozzle 702 constitute a leak opening, but the configuration of the leak opening is not limited to this, and the front end face of the movable nozzle 703 An independent leakage opening may be provided so as to penetrate through 703d, and the front side notch portion 703i and the front side may be provided without intentionally providing the front end notch portion 703j in the configuration of the modified example shown in FIGS. The leakage opening may be configured only by the direction opening 702f. In other words, in the present invention, the leak opening is provided so that the hot air can be leaked from the movable nozzle 703 when the movable nozzle 703 is in the storage position stored in the fixed nozzle 702. For example, the specific configuration is not particularly limited.

  A rack 703k is formed on the left side surface 703b of the movable nozzle 703 over substantially the entire length. A pinion gear 705a is engaged with the rack 703k. The pinion gear 705a is a part of the gear mechanism 705, and this gear mechanism 705, together with the drive motor 704, constitutes a drying nozzle drive mechanism (advance / retreat drive mechanism) that drives the movable nozzle 703 to advance / retreat. These are provided at positions facing the rack 703k in the case 701.

  The drive motor 704 is a DC motor that can rotate forward and backward, and the rotation of the drive motor 704 is decelerated by a gear mechanism 705 composed of a plurality of gears and transmitted to the pinion gear 705a. Since the pinion gear 705a is meshed with the rack 703k, the movable nozzle 703 can be slid in the fixed nozzle 702 by rotating the drive motor 704. Therefore, the movable nozzle 703 moves forward and backward. Moving.

  Further, as shown in FIG. 10, it is preferable that side ribs 703n are provided on the right side surface 703b opposite to the left side surface 703b on which the rack 703k is provided at a position close to the back surface 703m. Thereby, sliding of the movable nozzle 703 in the fixed nozzle 702 can be made smoother.

  Further, as shown in FIG. 11, a U-shaped cut portion 703h cut in a substantially U shape from the rear end to the front is provided on the back surface 703m of the movable nozzle 703. As a result, when the movable nozzle 703 is stored in the fixed nozzle 702 (storage position), as shown in FIG. 6, the thermistor 710 provided on the protrusion 702d of the flat surface 702c is exposed in the movable nozzle 703. Can do.

  Here, if the movable nozzle 703 is in the dry position, for example, the washing water adhering to the local area or the heel part falls on the movable nozzle 703, or the user accidentally urinates in this state, or When water is applied to the movable nozzle 703 during cleaning, the aqueous liquid that has entered the movable nozzle 703 is drained into the toilet 600 through the drain hole 703g provided in the curved surface portion 703f. When the liquid is applied to the movable nozzle 703, there is a risk that the liquid will enter the depth of the movable nozzle 703, and the back surface 703m of the movable nozzle 703 may be stored in the fixed nozzle 702 in a wet state. There is.

  On the other hand, if the U-shaped cut portion 703h is provided at the rear end of the movable nozzle 703, the inside of the wet movable nozzle 703 and the wet back surface 703m may be positioned above the thermistor 710. Avoided. Therefore, the possibility that the aqueous liquid that has entered the movable nozzle 703 adheres to the thermistor 710 is suppressed, and the temperature detection accuracy of the thermistor 710 can be improved. Therefore, the control unit 204 can achieve a stable hot air temperature.

  Here, the specific configuration of the U-shaped cut portion 703h is not particularly limited. When the movable nozzle 703 is stored in the fixed nozzle 702 at the rear end portion of the movable nozzle 703, a temperature detector such as the thermistor 710 or the like. May be a cut portion cut into the front side so that the length can be exposed in the movable nozzle 703. Therefore, the structure cut into V shape instead of U shape may be sufficient, and the structure cut into other shapes may be sufficient.

  In the present embodiment, as described in the above-described positional relationship of the functional units, the drying unit 700 is preferably provided as close to the central portion of the main body 200 as possible. It is preferable to be provided adjacent to the cleaning nozzle unit 103 having the highest priority provided in the section. Therefore, the movable nozzle 703 used in the present embodiment has the trapezoidal air outlet 703e, the front side cutout 703i, the curved and inclined bottom surface 703a, and the curved surface portion 703f provided in the vicinity of the air outlet 703e. It is particularly preferable.

  In the configuration of the present embodiment, since the drying unit 700 is provided on the left side of the cleaning nozzle unit 103, the movable nozzle 703 employs a configuration that biases the warm air toward the right side closer to the center. However, the present invention is of course not limited to this, and if the drying unit 700 is provided on the right side of the cleaning nozzle unit 103, the movable nozzle 703 is configured to bias the warm air toward the left side closer to the center. Adopt it.

[Operation of sanitary washing device]
Next, an example of the operation of the sanitary washing device 100 having the above-described configuration will be specifically described with reference to FIG. FIG. 14 is a time chart showing the relationship between the energization rate to the heater unit 708 and the hot air temperature with respect to the advance position of the movable nozzle 703 when the sanitary washing device 100 starts the drying operation. The vertical axis in FIG. 14 is the (advance) position of the movable nozzle 703, the energization rate to the heater unit 708, and the hot air temperature from the top, and the horizontal axis is the elapsed time.

  First, when a user enters a toilet room, first, when the human body detection sensor 201 detects a human body, the toilet lid 300 is automatically opened by the toilet seat toilet lid opening / closing unit under the control of the control unit 204, and the toilet seat 400 is built in. The energization of the toilet seat heater is started. Thereby, heating of the toilet seat 400 is started and the temperature is raised until the temperature of the toilet seat 400 reaches a set temperature. If the seat sensor 202 detects a user seated on the toilet seat 400, the cleaning nozzle unit 103 and the drying unit 700 can be operated by the remote controller 500 under the control of the control unit 204.

  If the user operates the remote controller 500 to start the cleaning operation after the stool is finished, the bottom cleaning nozzle 103a of the cleaning nozzle unit 103 advances from the main body 200 under the control of the control unit 204, and the cleaning is performed. Blow out water to clean the user's area. Thereafter, when the user operates the remote controller 500 to end the cleaning, the control unit 204 controls the local cleaning to be completed, and the buttocks cleaning nozzle 103a is housed in the main body 200.

  Next, when the user operates the remote controller 500 to start a drying operation, the control unit 204 starts to advance the bidet nozzle 103b, and the nozzle shutter 203 is opened by the bidet nozzle 103b. Subsequently, energization of the heater unit 708, the fan motor 709, and the drive motor 704 of the drying unit 700 is started. Thereafter, the control unit 204 determines the room temperature at the time of use from the temperature data detected by the thermistor 710, and determines the energization rate to the heater unit 708 set corresponding to the room temperature. This energization rate is referred to as a set energization rate.

  Then, the control unit 204 drives the drive motor 704 to start the operation of moving the movable nozzle 703 from the storage position as shown in the upper part of FIG. As a result, the movable nozzle 703 starts to advance from the lower side of the opened nozzle shutter 203 toward the center of the toilet 600 in an obliquely rightward direction. Here, the control unit 204 starts energizing the heater unit 708 and the fan motor 709 while the air outlet 703e of the movable nozzle 703 passes under the nozzle shutter 203. Thereby, the blowing of warm air is started.

  In the present embodiment, immediately after energization is started, the heater unit 708 is energized at an energization rate of 150% of the set energization rate. For example, if the set energization rate when the room temperature is 10 ° C. is set to 50%, the power consumption is about 150 W, so the power consumption immediately after the start of energization is 225 W (see the middle stage in FIG. 14). . Therefore, the control unit 204 increases the temperature of the hot air in a short time as shown in the lower part of FIG. The energization rate to the fan motor 709 is maintained at 100% until the drying operation is completed.

  As described above, in the present embodiment, when the user operates the remote controller 500 (operator) to start the operation of the drying unit 700 (drying mechanism), the control unit 204 (controller) is driven forward / backward. After starting the advance of the movable nozzle 703 by the mechanism (drive motor 704 and gear mechanism 705) and before the movable nozzle 703 reaches the dry position, the fan motor 709 (blower) and the heater unit 708 (heater) Control to start the operation. Thus, immediately after the start of the blowing of warm air, most of the cold air staying in the movable nozzle 703 or the warm air that has not been sufficiently warmed (collectively referred to as cold air) is the nozzle shutter 203. Blocked. Thereby, cold air will flow toward the lower part of toilet 600 by nozzle shutter 203, and it can avoid a possibility that cold air may hit a user's local part and a buttocks.

  Further, when the air outlet 703e of the movable nozzle 703 protrudes from below the nozzle shutter 203, hot air is blown upward from the air outlet 703e. Here, the warm air from the outlet 703e hits the user's buttocks from the middle of the moving movement of the movable nozzle 703. The temperature of the hot air blown out at this time may be lower than the set temperature although it is not the cold air described above. However, the part where the hot air first hits is behind the buttocks where the cleaning water does not adhere in the cleaning operation, and before the blowout port 703e faces the vicinity of the local portion where the cleaning water adheres, Has risen to near the set temperature. Therefore, even if a relatively low temperature hot air hits the back of the buttock, it is possible to avoid the user from feeling cold air.

  Next, when the hot air temperature detected by the thermistor 710 reaches 65 ° C., which is 10 ° C. lower than the preset temperature, during the advancing movement of the movable nozzle 703, the control unit 204 energizes the heater unit 708. The rate is reduced by 50% to 100%, which is the set energization rate, and energization is continued. As a result, the temperature rise of the warm air slowly reaches the set temperature. Therefore, the hot air temperature is controlled so as not to overshoot above the set temperature. In addition, after the thermistor 710 detects the set temperature of 75 ° C., the thermistor 710 constantly detects the hot air temperature, and the control unit 204 energizes the heater unit 708 so as to maintain the set temperature of 75 ° C. To control.

  In the present embodiment, energization control for the heater unit 708 is performed by phase control from the start of energization until reaching the set temperature, and after reaching the set temperature, it is performed by ON / OFF control.

  Next, when the movable nozzle 703 reaches the drying position, the drive motor 704 stops, and the blowing of warm air continues from the outlet 703e of the movable nozzle 703 toward the local area wetted by the cleaning. Here, the movable nozzle 703 can be periodically moved back and forth when the user operates the remote controller 500 in a state where the blowing of warm air continues at the drying position. As a result, a wide range of drying is possible and the drying efficiency can be increased. Moreover, since it is avoided that warm air concentrates and hits a specific site | part, it can prevent that a part of human body becomes locally hot, and can improve comfort.

  Thereafter, when the user performs an operation to end drying with the remote controller 500, the control unit 204 stops energization of the fan motor 709 and the heater unit 708 and rotates the drive motor 704 in the reverse direction. As a result, the blowing of warm air stops and the movable nozzle 703 moves backward into the fixed nozzle 702. Thereafter, when the movable nozzle 703 reaches the storage position, the drive motor 704 stops. At this time, when the front end of the movable nozzle 703 is retracted from the front surface of the main body 200, the nozzle shutter 203 is closed by its own weight and the movable nozzle 703 is concealed.

  If energization to the fan motor 709 and the heater unit 708 is started when the movable nozzle 703 protrudes to the drying position, cold air staying in the drying unit 700 is used immediately after the energization is started. It blows out toward the person's local part or buttocks. Further, even after the staying cold air is released, it takes a certain time for the warm air to reach a predetermined temperature. Therefore, the user feels a cold wind feeling (uncomfortable feeling) until a certain time has elapsed from the start of the air blowing. In particular, since a large amount of washing water adheres to the local part immediately after washing and the collar part in the vicinity thereof, a stronger feeling of cold wind is felt when cold air hits it.

  On the other hand, in the present embodiment, by performing the above-described control, it is possible to suppress the cold air from being blown out to the user's local area or the buttocks, and to raise the temperature to a comfortable temperature from the start of the air blowing. The wind is blown against the local area or the buttocks. Thereby, the user can dry a local part etc. comfortably, without memorizing a cold wind feeling.

  Here, in the present embodiment, the control unit 204 controls the heater unit 708 so that the temperature of the hot air formed by the fan motor 709 and the heater unit 708 does not exceed a preset dry value. Control to adjust the output of the. The dry value referred to here is the set temperature of 75 ° C. in the present embodiment, and the output is adjusted by adjusting the power supply rate.

  In the present embodiment, immediately after the start of the operation of the heater unit 708, the control unit 204 sets the output of the heater unit 708 to a startup output value larger than the standard output value for maintaining the dry value, When the temperature of the hot air detected by the thermistor 710 reaches an adjustment value set as a value lower than the dry value, the output of the heater unit 708 is reduced from the start output value to the standard output value. Control is in progress. The adjustment value here is 65 ° C., which is 10 ° C. lower than the set temperature, the standard output value is the power consumption realized by the set energization rate (100% energization rate), and the start output value is 150%. It is the power consumption realized by the energization rate.

  The control of the control unit 204 in the present invention is not limited to the above-described configuration. Therefore, the dry value and the adjustment value set as the temperature of the hot air, and the standard output of the heater unit 708 (strictly, the heater wire 708a) are used. The value and the start output value are not specified by the value. Further, the method for adjusting the output of the heater such as the heater unit 708 is not limited to the adjustment of the energization rate, and other known methods can be used.

  Note that the specific control method in the present embodiment is not particularly limited. That is, in the present embodiment, when the controller such as the control unit 204 operates the operating device such as the remote controller 500 to start the operation of the drying mechanism such as the drying unit 700, the drying mechanism is provided. The blower and the heater are operated, the temperature value detected by the temperature detector is acquired, and control for adjusting the output of the heater using the temperature value may be performed. Also, the operation of the blower and the heater is performed. Control to start the advance of the movable nozzle 703 may be performed before the operation.

(Embodiment 2)
In the first embodiment, the control unit 204 performs control to start energization of the fan motor 709 and the heater unit 708 after the advance movement of the movable nozzle 703 is started first. First, energization of the fan motor 709 and the heater unit 708 is started, and then the moving movement of the movable nozzle 703 is started. This configuration will be specifically described with reference to FIG. FIG. 15 is a time chart showing the relationship between the energization rate to the heater unit 708 and the hot air temperature with respect to the advance position of the movable nozzle 703 when the sanitary washing device 100 starts the drying operation. The unit indicated by the axis is the same as in FIG.

  Since the configuration of the sanitary washing apparatus in the present embodiment is the same as that in the first embodiment, a specific description thereof will be omitted. The present embodiment is different from the first embodiment in that the control sequence of the drive motor 704, the heater unit 708, and the fan motor 709 is different in the drying operation.

  In the present embodiment, when the start of the drying operation is operated by the remote controller 500, the control unit 204 starts energizing the heater unit 708 and the fan motor 709 without operating the drive motor 704. In the same way as in the first embodiment, the unit 708 is energized until the temperature detected by the thermistor 710 reaches 65 ° C. (adjusted value), and the energization rate (starting output value) is 150% of the set energization rate. Energization is performed at the energization rate), and then the energization rate is reduced to the set energization rate (the energization rate that realizes the standard output value).

  At this time, the low temperature warm air or cold air sent to the movable nozzle 703 is forwardly provided from a leakage opening provided at the front end of the movable nozzle 703 and formed by the front end notch 703j and the inner peripheral surface of the fixed nozzle 702. Erupted. Alternatively, if the fixed nozzle 702 is provided with a front side opening 702f, the low-temperature hot air or cold air is laterally generated by a leakage opening formed by the front side opening 702f and the front side notch 703i. Erupted toward.

  Further, the low-temperature hot air or cold air ejected from the leak opening hits the nozzle shutter 203 and flows downward of the toilet 600. Therefore, cold air staying in the movable nozzle 703 and low-temperature hot air that is not sufficiently heated are avoided from hitting the user's buttocks. Further, since the opening area of the leakage opening is smaller than that of the air outlet 703e, air stays gently in the movable nozzle 703 at the storage position. Therefore, the temperature of the air in the movable nozzle 703 can be raised in a short time.

  When the temperature of the hot air detected by the thermistor 710 reaches a set temperature of 75 ° C. (dry value), the control unit 204 starts the operation of the drive motor 704 and moves the movable nozzle 703 from the storage position to the dry position. Let Since the control sequence after reaching the drying position is the same as in the first embodiment, the description thereof is omitted.

  As described above, in the present embodiment, when the user operates the operation device such as the remote controller 500 to start the operation of the drying mechanism such as the drying unit 700, the controller such as the control unit 204 The temperature of the thermistor 710 or the like indicates that the temperature of the hot air has reached the dry value since the operation of the fan such as the motor 709 and the heater such as the heater unit 708 (strictly, the heater wire 708a) is started first. If detected by the detector, control is performed to start the advance of the movable nozzle 703 by the advance / retreat drive mechanism.

  Thereby, when the advance operation of the movable nozzle 703 is started, the temperature of the hot air has already risen to the set temperature (dry value), so that the hot air hitting the user's buttocks in the process of the advance operation has already been The set temperature has been reached. Therefore, the user does not feel a cold wind and can ensure a high level of comfort.

  According to the above configuration, since the energization to the blower and the heating means is started before the movable nozzle reaches the drying position, the temperature of the hot air is increased when the movable nozzle reaches the drying position. The user does not feel uncomfortable. That is, since warm air heated to a comfortable temperature from the start of ejection can be ejected, the user does not feel cold and therefore does not feel uncomfortable for the user. As a result, it is possible to provide a comfortable drying means for supplying comfortable warm air immediately after the start of drying.

  Alternatively, as another example, a main body placed on a toilet bowl, a toilet seat pivotally supported on the main body, a cleaning means for ejecting cleaning water toward a human body part seated on the toilet seat, A drying unit that ejects warm air toward a local body seated on a toilet seat, a control unit that controls the cleaning unit and the drying unit, and an operation unit that operates the control unit, the drying unit including a blower, A heating means, a temperature detection means, a fixed nozzle, a movable nozzle, and a drive means for moving the movable nozzle forward and backward, the movable nozzle having a jet port at a front end, and inserted into the fixed nozzle to be in a storage position. When the drying position can be moved forward and backward, and the drying operation is performed by the operation means, the control means starts energization to the blower and the heating means, and the temperature detection means detects a set temperature (dry value). Once you have said driving hand Mention may also be a configuration to start the drive.

  According to the above configuration, the advance operation of the movable nozzle is started after the warm air temperature is raised to the set temperature optimum for drying. Therefore, there is virtually no cold air hitting the human body part or the buttocks, and the user is not uncomfortable. As a result, it is possible to provide a comfortable drying means for supplying comfortable warm air immediately after the start of drying.

  In the above configuration, the heating means is energized with a large energization capacity immediately after the start of energization, and the energization capacity is decreased when the temperature detection means detects a predetermined temperature (adjustment value) lower than a set temperature. Preferably there is.

  According to the said structure, it heats up at a high temperature increase rate initially, and when it approaches set temperature, it can suppress that a temperature increase rate falls and overshoots set temperature. Therefore, the temperature can be raised in a short time and the temperature can be accurately set.

  Further, as another preferred example of the sanitary washing device according to the present invention, a main body placed on a toilet bowl, a toilet seat pivotally supported on the main body, and a human body seated on the toilet seat A cleaning means for ejecting washing water; and a drying means for ejecting warm air toward a human body part seated on the toilet seat, wherein the drying means includes a blower, a heating means, a temperature detection means, a fixed nozzle, Including a movable nozzle provided with a spout at the front end, the movable nozzle is inserted into the fixed nozzle, advances and retreats from the main body, and blows warm air from the spout toward the human body part seated on the toilet seat, The rear end of the fixed nozzle is located inside the main body, the front end of the fixed nozzle is located at the lower part of the front surface of the main body, and the bottom of the fixed nozzle is provided with an inclined portion (inclined surface) lower in the front than the rear. The rear end of the inclined part A flat portion (flat surface) that is connected and has a gentler slope than the inclined portion is provided, the temperature detecting means is installed on the flat portion, and the bottom of the movable nozzle is the temperature detection in a state where the movable nozzle is retracted. The structure which does not cover a means is mentioned.

  According to the above configuration, since the temperature detecting means is installed in the flat portion which is the highest position of the rear end of the inclined portion of the fixed nozzle, when the movable nozzle has advanced, it is separated from the ejection hole and has a large height difference. Therefore, it is difficult to reach the water at the time of cleaning, and for example, even when the movable nozzle to which the water at the time of cleaning adheres is retracted into the fixed nozzle, it does not cover the temperature detection means, so it adheres to the bottom of the movable nozzle. Therefore, the temperature detection means can be kept in a dry state without falling or adhering to the temperature detection means, so that the temperature of the hot air can be stabilized. Thus, a sanitary washing device having a comfortable drying means with a stable temperature of hot air can be obtained by suppressing detection errors caused by water adhering to the temperature detecting means for controlling the hot air temperature of the drying means. Can do.

  In the above configuration, the movable nozzle has a cylindrical shape, is provided with a cutout portion cut forward from the rear end of the bottom, and the temperature detection means is disposed inside the cutout portion in a state in which the movable nozzle is retracted. It is preferable that it is the structure made. As a result, since the temperature detecting means is disposed inward of the notch, the water adhering to the bottom of the movable nozzle does not adhere to the temperature detecting means, and the entire length of the movable nozzle is divided by the notch. Since it can be lengthened, the advancing distance can be increased and the advance / retreat operation can be stabilized.

  Moreover, in the said structure, it is preferable in the structure which provided the projection part which protruded upwards in the said flat part, and installed the said temperature detection means in the said projection part. Thereby, even when a large amount of water falls on the flat portion, it is possible to prevent water from adhering to the temperature detecting means, and it is possible to further stabilize the temperature detection.

  Alternatively, in the configuration, a gap is formed between the inclined portion of the fixed nozzle and the bottom portion of the movable nozzle, the gap communicates from the rear end to the front end of the inclined portion, and the front end and the rear end of the gap are It is preferable to have a configuration in which the water that has entered the drying means through the gap can be drained. Accordingly, even when a relatively large amount of water enters the flat portion, most of the water is discharged out of the nozzle through the gap, so that it is possible to more reliably prevent water from adhering to the temperature detecting means. .

  Here, as described above, in the sanitary washing apparatus, the present invention can suppress the operation of the overheat protector more than necessary, and further suppress the user from feeling uncomfortable with the cold air. Or, it is possible to reduce the concern that the thermistor that controls the temperature of the hot air is covered with water, and to eliminate the error in the temperature detection of the thermistor. Therefore, the technical idea of the present invention can be applied not only to a sanitary washing apparatus, but also to other home appliances that generate or use hot air, or other hot water heaters that use hot water, etc. It can also be applied to other consumer devices.
