The user can set the hot water temperature by operating the operation unit 45.

  The electrolytic cell 52 is provided downstream of the heat exchanger 51. The electrolytic cell 52 has a pair of electrodes, and electrolyzes wash water (tap water) flowing between the electrodes based on the energization control signal transmitted from the control unit 44. The electrolytic bath 52 generates a liquid containing hypochlorous acid (HClO) (hereinafter referred to as “functional water”) by electrolyzing chlorine ions contained in the cleaning water.

  The vacuum breaker 53 is provided downstream of the electrolytic cell 52. The vacuum breaker 53 includes, for example, a flow path for flowing water, an intake port for taking air into the flow path, and a valve mechanism for opening and closing the intake port.

That is, the electromagnetic pump 54 varies the flow state of the water flowing in the water channel. The electromagnetic pump 54 is connected to the control unit 44. The electromagnetic pump 54 varies the flow state of water based on the control by the control unit 44. In the specification of the present application, “pulsation” refers to fluctuations in pressure in the water channel caused by the electromagnetic pump 54. The electromagnetic pump 54 varies the pressure of water in the water channel.

  The cleaning nozzle 34 has a water discharge part 35. The water discharger 35 includes, for example, a butt cleaning water discharge hole 35a, a butt soft water discharge hole 35b, and a bidet cleaning water discharge hole 35c.

  Further, the cleaning nozzle 34 includes a buttocks cleaning channel FC1, a buttocks soft channel FC2, a bidet cleaning channel FC3, and a wide bidet cleaning channel FC4. The buttocks cleaning channel FC1 is connected to the buttocks cleaning water discharge hole 35a and supplies cleaning water or functional water to the buttocks cleaning water discharging hole 35a. The buttocks soft flow path FC2 is connected to the buttocks soft water discharge hole 35b, and supplies cleaning water or functional water to the buttocks soft water discharge hole 35b. The bidet cleaning channel FC3 and the wide bidet cleaning channel FC4 are connected to the bidet cleaning water discharge hole 35c and supply cleaning water or functional water to the bidet cleaning water discharge hole 35c. However, the water discharge holes and flow paths of the cleaning nozzle 34 are not limited to these. As described above, the number of water discharge holes may not coincide with the number of flow paths, or may be the same as the number of flow paths. Moreover, you may share a some washing | cleaning water discharging hole by the same hole.

  The cleaning water or functional water sent to the cleaning nozzle 34 is discharged upward from the water discharge portion 35. The wash water discharged from the water discharge unit 35 is used for local cleaning of the user seated on the toilet seat 14. In the cleaning nozzle 34, bidet cleaning is performed by supplying cleaning water from the bidet cleaning channel FC3 to the bidet cleaning water discharge hole 35c, and cleaning water is supplied from the wide bidet cleaning channel FC4 to the bidet cleaning water discharging hole 35c. By doing so, wide bidet cleaning is performed. The functional water is used for washing the water discharge holes 35a to 35c and the water channels leading to the water discharge holes 35a to 35c. As described above, the cleaning nozzle 34 includes the four flow paths FC1 to FC4 and is configured to discharge the cleaning water or the functional water supplied from each of the four flow paths FC1 to FC4.

  The flow control / flow path switching valve 55 is provided between the electromagnetic pump 54 and the cleaning nozzle 34. The flow control / flow path switching valve 55 determines the destination of the washing water or the functional water supplied via the electromagnetic pump 54 to the buttocks washing channel FC1, the buttocks soft channel FC2, the bidet washing channel FC3, and the wide bidet washing channel. Switch to any of FC4, nozzle cleaning chamber 36, spray nozzle 38, and first deodorizing unit 41. Further, the flow control / flow path switching valve 55 changes the water discharge flow rate of the cleaning water discharged from the water discharge holes 35 a to 35 c of the cleaning nozzle 34.

  The nozzle cleaning chamber 36 has a water discharge part 36a. The nozzle cleaning chamber 36 performs cleaning of the outer surface of the cleaning nozzle 34, that is, body cleaning, by discharging cleaning water or functional water from the water discharge portion 36a.

  The spray nozzle 38 sprays cleaning water or functional water on the surface of the bowl portion 4 a of the toilet 4. The spray nozzle 38 may be provided inside the casing 20 or attached to the outside of the casing 20.

  For example, the control unit 44 sprays water droplets from the spray nozzle 38 onto the surface of the bowl portion 4a of the toilet 4 in response to detection of the user's entry by the human body detection sensor 32. That is, the controller 44 wets the surface of the bowl portion 4a of the toilet 4 with water droplets before the user uses the toilet 4. Thereby, the dirt adhering to the surface of the bowl part 4a can be reduced.

  Further, the control unit 44, for example, from the spray nozzle 38 to the bowl portion of the toilet 4 when a predetermined time (for example, after 90 seconds) has elapsed since the human body detection sensor 32 no longer detects the user in the toilet room. Functional water is sprayed on the surface of 4a. That is, the control unit 44 wets the surface of the bowl portion 4a with functional water (hypochlorous acid water) after the user has washed away dirt and finished using the toilet bowl 4. Thereby, it can suppress that the microbe which becomes a bad odor increases in the bowl part 4a. It is possible to prevent malodor from being released from the toilet 4.

  The second deodorizing unit 42 is provided in the casing 20. The second deodorizing unit 42 sucks the air in the bowl portion 4a of the toilet 4 and reduces malodorous components contained in the sucked air, and then discharges it out of the casing 20, whereby the inside of the bowl portion 4a. Deodorize the air. The 2nd deodorizing unit 42 is connected to the control part 44, and deodorizes the air in the bowl part 4a based on control of the control part 44. FIG. For example, when the seating detection sensor 31 detects that the user has left the toilet seat 14, the control unit 44 operates the second deodorizing unit 42 for a predetermined time.

  The first deodorizing unit 41 is provided in the casing 20. The first deodorizing unit 41 sucks air in the toilet room. The air in the toilet room mainly refers to air outside the toilet 4 (air other than in the bowl portion 4a). The first deodorizing unit 41 collects or decomposes malodorous components contained in the sucked air. The “bad odor component” is, for example, a component such as ammonia or trimethylamine. The first deodorizing unit 41 discharges air that has collected or decomposed malodorous components and the like to the outside (toilet room) of the casing 20. Thereby, the 1st deodorizing unit 41 deodorizes the air in a toilet room.

  The first deodorizing unit 41 includes a dust collection filter 60, a fan (air blowing unit) 61, a deodorizing filter 62, a spray unit 63, a duct unit 64, an intake port 65, and an exhaust port 66.

  The fan 61 sucks air in the toilet room from the air inlet 65. The duct portion 64 guides the air sucked by the fan 61 to the exhaust port 66. The air sucked as the fan 61 is driven is discharged from the exhaust port 66 to the toilet room via the duct portion 64. The dust collection filter 60 is provided on the upstream side of the fan 61, and suppresses the dust and dust contained in the sucked air from being sent to the fan 61.

  The deodorizing filter 62 is provided in the duct portion 64. The deodorizing filter 62 is disposed between the fan 61 and the exhaust port 66 in the duct portion 64. The spray part 63 is provided above the deodorizing filter 62. The spraying unit 63 sprays the cleaning water or functional water supplied from the flow control / flow path switching valve 55 toward the deodorizing filter 62 from above the deodorizing filter 62 based on the control of the control unit 44. Thereby, the spray unit 63 supplies water to the deodorizing filter 62.

  The deodorizing filter 62 has, for example, a porous structure, and retains cleaning water or functional water sprayed from the spray unit 63.

When the fan 61 is activated, the air in the toilet room sucked from the air inlet 65 passes through the deodorizing filter 62. When air passes through the deodorizing filter 62 in a state where the deodorizing filter 62 retains moisture, malodorous components contained in the air are taken into the moisture retained in the deodorizing filter 62. For example, ammonia (NH ₃ ) contained in the air dissolves in the moisture held in the deodorizing filter 62. Thereby, the malodorous component etc. which are contained in the air can be reduced.

  Air in which malodorous components are reduced is discharged from the exhaust port 66 to the toilet room. In this way, the first deodorizing unit 41 can collect or decompose malodorous components and the like that are always present in the toilet room. Therefore, when the user enters the toilet room, the user is less likely to inhale odors due to malodorous components or the like that are permanently present in the toilet room, and can use the toilet room comfortably.

  For example, the control unit 44 stops the operation of the fan 61 in a time zone in which the user's toilet device 2 is used less frequently. And the control part 44 operates the fan 61 and operates the spray part 63 regularly, and keeps the water | moisture content in the deodorizing filter 62 in the time slot | zone when the user's toilet device 2 is used frequently.

  Thereby, in the time zone when the user is likely to enter the toilet room, it is possible to remove the odor that is always present in the toilet room. Therefore, it is possible to suppress the user from feeling uncomfortable by sucking the odor that is always present in the toilet room.

  Further, the control unit 44 periodically cleans the deodorizing filter 62 at a frequency of once a day, for example. When the deodorizing filter 62 is washed, the control unit 44 sprays a larger amount of functional water from the spraying unit 63 onto the deodorizing filter 62 than when deodorizing, and rinses the deodorizing filter 62 with functional water. Thereby, for example, the increase in bacteria in the deodorizing filter 62 can be suppressed.

  The deodorizing filter 62 is detachably attached to the duct portion 64. In other words, the duct part 64 hold | maintains the deodorizing filter 62 so that attachment or detachment is possible. The deodorizing filter 62 is detachable from the outside of the casing 20. Thus, for example, when dirt such as paper dust contained in the sucked air or scale generated by spraying water adheres to the deodorizing filter 62, the deodorizing filter 62 can be removed and cleaned. . Thus, in the sanitary washing device 10, the maintenance of the deodorizing filter 62 can be easily performed, and a decrease in the performance of the first deodorizing unit 41 can be suppressed.

FIG. 3 is a plan view illustrating the sanitary washing device according to the embodiment.
FIG. 3 shows a plan view of the sanitary washing device 10 with the case cover 22 omitted. As illustrated in FIG. 3, the casing 20 further includes a base plate 24. The base plate 24 closes the lower end of the case cover 22. In other words, the case cover 22 is attached on the base plate 24. In the sanitary washing device 10, the nozzle unit 33, the first deodorizing unit 41, the second deodorizing unit 42, the control unit 44, the flow path opening / closing valve 50, the heat exchanger 51, the electrolytic cell 52, the vacuum breaker 53, the electromagnetic pump 54, and Each part such as the flow control / flow path switching valve 55 is mounted on the base plate 24.

  In this example, the sanitary washing device 10 further includes a hot air drying unit 43. The hot air drying unit 43 blows warm air toward the human body part (such as “buttock”) of the user sitting on the toilet seat 14, thereby drying the human body part of the user wet by the cleaning. The hot air drying unit 43 is connected to the control unit 44 and switches between blowing and stopping the hot air based on a command from the control unit 44 to change the temperature of the hot air. The hot air drying unit 43 is provided as necessary and can be omitted.

  The nozzle unit 33 is provided approximately at the center of the base plate 24 in the left-right direction. The hot air drying unit 43 is provided adjacent to the nozzle unit 33, for example. The 2nd deodorizing unit 42 is provided adjacent to the warm air drying unit 43, for example. The first deodorizing unit 41 is provided adjacent to the second deodorizing unit 42, for example.

  As described above, the second deodorizing unit 42 is provided side by side with the first deodorizing unit 41 in the casing 20. The exhaust port 42 a of the second deodorizing unit 42 is provided side by side with the exhaust port 66 of the first deodorizing unit 41.

  In this example, the exhaust ports 42a and 66 are provided facing rearward and arranged side by side in the left-right direction. The exhaust ports 42 a and 66 are disposed in the vicinity of the inner surface of the case cover 22. For example, the exhaust ports 42a and 66 may be provided sideways and arranged side by side in the front-rear direction. For example, the exhaust ports 42a and 66 may be arranged so as to overlap in the vertical direction.

  Further, the exhaust ports 42a and 66 are not necessarily arranged. For example, the exhaust port 42a of the second deodorizing unit 42 may be provided toward the rear, and the exhaust port 66 of the first deodorizing unit 41 may be provided toward the side. Moreover, when providing each exhaust port 42a, 66 side by side, the 1st deodorizing unit 41 and the 2nd deodorizing unit 42 do not necessarily need to be adjacent. For example, the first deodorizing unit 41 and the second deodorizing unit 42 may be arranged apart from each other, and only the exhaust ports 42a and 66 may be arranged side by side via a duct or the like. Arrangement | positioning of the 1st deodorizing unit 41, the 2nd deodorizing unit 42, and the warm air drying unit 43 is not restricted above, Arbitrary arrangement | positioning may be sufficient.

  The second deodorizing unit 42 includes a deodorizing member 42b such as a deodorizing catalyst or a deodorizing filter. The 2nd deodorizing unit 42 reduces the malodorous component etc. which are contained in the sucked air by letting the sucked air pass through the deodorizing member 42b. The deodorizing member 42b is detachably attached to the second deodorizing unit 42. Thereby, maintenance, such as cleaning and replacement | exchange of the deodorizing member 42b, can be performed easily. The deodorizing member 42b is attached, for example, in a state of facing the exhaust port 42a, and is attached / detached via the exhaust port 42a.

  In addition, as illustrated in FIG. 3, the sanitary washing device 10 further includes a drainage basin 80. The drainage basin 80 is tubular. The drainage basin 80 has a tubular shape with a substantially rectangular cross section, for example. The drainage basin 80 guides the water drained from the first deodorizing unit 41 to the outside of the casing 20. The drainage basin 80 drains the water drained from the first deodorizing unit 41 to the bowl portion 4 a of the toilet 4 through the base plate 24. The drainage basin 80 drains, for example, excess water that is not retained by the deodorizing filter 62 or a large amount of functional water supplied when the deodorizing filter 62 is washed to the bowl portion 4a.

  The drainage basin 80 is a hard pipe line provided on the base plate 24. The drainage basin 80 does not substantially change the internal pipe shape without causing elastic deformation or the like in a normal use state. Thereby, compared with the case where it drains with the tube etc. which have flexibility, the water drained from the 1st deodorizing unit 41 can be drained to the exterior of the casing 20 more appropriately. Moreover, by making the drainage basin 80 into a tubular shape having a substantially rectangular cross section, for example, the surface tension in the pipe line can be reduced and drainage can be made easier than in the case of a substantially circular cross section.

  The base plate 24 has a drainage groove 24a. The drainage groove 24 a guides the wash water leaked from the flow path opening / closing valve 50 to the outside of the casing 20. The drain groove 24 a drains the wash water leaked from the flow path opening / closing valve 50 to the bowl portion 4 a of the toilet 4. As shown in FIG. 3, the sanitary washing device 10 removes water drained from the first deodorizing unit 41 or water leaked from the flow path opening / closing valve 50 from the vicinity of the center in the left-right direction of the base plate 24. It drains into the bowl part 4a.

FIG. 4A and FIG. 4B are rear views showing the sanitary washing device according to the embodiment.
As illustrated in FIG. 4A and FIG. 4B, the casing 20 includes an opening 20 a and a lid 26. The opening 20 a is provided to face the exhaust port 66 of the first deodorizing unit 41 and to face the exhaust port 42 a of the second deodorizing unit 42. In this example, the opening 20 a is provided on the back surface of the casing 20. For example, when the exhaust ports 42 a and 66 are provided facing sideways, the opening 20 a is provided on the side surface of the casing 20.

  The lid part 26 is detachably attached to the opening part 20a. The lid 26 closes the opening 20a in a state where the lid 26 is attached to the opening 20a. 4A shows a state in which the lid portion 26 is attached, and FIG. 4B shows a state in which the lid portion 26 is removed.

  The lid portion 26 has a vent hole 26a that allows the air discharged from the first deodorizing unit 41 to pass therethrough, and a vent hole 26b that allows the air discharged from the second deodorizing unit 42 to pass therethrough. The air discharged from the deodorizing units 41 and 42 is discharged to the outside of the casing 20 through the vent holes 26a and 26b.

  The lid portion 26 has, for example, a plurality of vent holes 26a and a plurality of vent holes 26b. Each vent hole 26a is partitioned by a louver 26c extending in the horizontal direction. Similarly, each air hole 26b is partitioned by a louver 26d extending in the horizontal direction. Each louver 26c, 26d has, for example, a flat plate shape that is inclined downward toward the rear (outside of the casing 20), and rectifies the air discharged from each deodorizing unit 41, 42 downward. In other words, each louver 26c, 26d is a louver.

FIG.5 and FIG.6 is sectional drawing showing a 1st deodorizing unit and a cover part.
FIG. 5 shows a state in which the first deodorizing unit 41 and the lid portion 26 are viewed from above.
FIG. 6 represents the state which looked at the 1st deodorizing unit 41 and the cover part 26 from the side.
6 represents a cross section taken along line A1-A2 of FIG. 5, and FIG. 5 represents a cross section taken along line B1-B2 of FIG.
As shown in FIGS. 5 and 6, the deodorizing filter 62 is held in the duct portion 64 so as to face the exhaust port 66. That is, the deodorizing filter 62 is held in the duct portion 64 so as to face the opening 20 a of the casing 20. Thereby, the deodorizing filter 62 can be attached or detached from the outside of the casing 20 through the opening 20 a and the exhaust port 66 by removing the lid portion 26.

  In this example, the entire deodorizing filter 62 faces the opening 20 a and the exhaust port 66. Thereby, the deodorizing filter 62 can be easily attached and detached. However, the entire deodorizing filter 62 does not necessarily have to face the opening 20 a and the exhaust port 66. That is, at least a part of the deodorizing filter 62 only needs to face the opening 20a and the exhaust port 66.

  As described above, the deodorizing filter 62 can be detached from the opening 20 a and the exhaust port 66 by removing the lid 26. In the sanitary washing device 10, the exhaust opening 20 a of the casing 20 also serves as an opening for attaching and detaching the deodorizing filter 62. This eliminates the need for a separate mechanism for attaching and detaching the deodorizing filter 62. For example, the aesthetic appearance of the sanitary washing device 10 can be improved as compared with a case where an opening for attaching / detaching the deodorizing filter 62 is separately provided.

  In the second deodorizing unit 42, the deodorizing member 42b is attached and detached as described above. In the sanitary washing device 10, the opening 20 a faces the exhaust port 66 of the first deodorizing unit 41 and faces the exhaust port 42 a of the second deodorizing unit 42. That is, the opening 20a also serves to exhaust the air discharged from the second deodorizing unit 42 and to attach / detach the deodorizing member 42b. Thereby, in the sanitary washing apparatus 10, compared with the case where the cover part which plugs up the exhaust port 42a of the 2nd deodorizing unit 42 is provided separately, a number of parts can be reduced, for example. For example, the manufacturing cost of the sanitary washing device 10 can be suppressed. For example, the aesthetic appearance of the sanitary washing device 10 can be further improved as compared with the case where a plurality of lids are provided.

  The deodorizing filter 62 has a filter main body 70 and a case portion 72. The filter body 70 is formed in a lattice shape, for example, and has a plurality of through holes 70a. For the filter body 70, for example, ceramics or the like is used. The case portion 72 has a frame shape surrounding the filter body 70 and holds the filter body 70. For the case portion 72, for example, a resin material or the like is used.

  The deodorizing filter 62 is held in the duct portion 64 with each through hole 70a facing in the vertical direction. Therefore, the deodorizing filter 62 allows air to pass in the vertical direction.

  The first deodorizing unit 41 is arranged with the intake port 65 facing downward. The fan 61 sucks air from below through an intake opening 22a (see FIG. 1) and an intake port 65 provided in the lower side of the case cover 22, and discharges the sucked air backward. As the fan 61, for example, a sirocco fan is used.

  The duct part 64 guides the air exhausted from the fan 61 to the rear, and allows the air to pass through the deodorizing filter 62 from below to above. The duct portion 64 guides the air that has passed through the deodorizing filter 62 to the rear, and discharges the air to the outside of the casing 20 through the exhaust port 66 and the vent hole 26 a of the lid portion 26.

  Thus, the 1st deodorizing unit 41 discharges the air inhaled from the side of casing 20 back. The position of the intake and exhaust of the first deodorizing unit 41 is not limited to the above, and may be an arbitrary position of the casing 20. For example, the air sucked from the side of the casing 20 may be deodorized and then discharged to the side of the casing 20 again.

  The fan 61 is disposed below the deodorizing filter 62. Thereby, when passing air from the lower side to the upper side with respect to the deodorizing filter 62, the air can be efficiently sent to the duct portion 64 and the deodorizing filter 62. Thereby, deodorization can be performed efficiently. For example, the shape of the duct part 64 can be simplified, the apparatus can be miniaturized, and the manufacturing cost can be reduced.

  Further, the fan 61 is arranged laterally with respect to the deodorizing filter 62. In other words, the fan 61 does not overlap the deodorizing filter 62 in the vertical direction. Thereby, even when the fan 61 is disposed below the deodorizing filter 62, it is possible to prevent the cleaning water or functional water sprayed from the spray unit 63 from being applied to the fan 61. For example, it can be suppressed that water is applied to the fan 61 and causes deterioration or failure of the fan 61.

  The duct portion 64 has a stay space 64a and an upper space 64b. The retention space 64 a is provided below the deodorizing filter 62, and temporarily retains the air sucked by the fan 61 below the deodorizing filter 62. In the deodorizing filter 62, it is difficult for air to flow compared to the duct portion 64. Therefore, in the stay space 64a located upstream of the deodorizing filter 62, air tends to stay as compared with other portions.

  Moreover, the duct part 64 receives the water droplet dripped from the deodorizing filter 62, and makes the water droplet WD adhere to the inner wall surface 64n forming the stay space 64a. That is, when water is supplied from the spray unit 63 to the deodorizing filter 62, the deodorizing filter 62 retains moisture, the inner wall surface 64n of the stay space 64a also gets wet, and the inner wall surface 64n also retains moisture.

  The upper space 64 b is provided above the deodorizing filter 62. The stay space 64a is wider than the upper space 64b. In other words, the volume of the stay space 64a is larger than the volume of the upper space 64b.

  In the deodorizing filter 62, the lower portion has more water than the upper portion due to gravity. For this reason, while letting air pass from the lower part to the upper part with respect to the deodorizing filter 62, the air is temporarily retained in the retention space 64a below the deodorizing filter 62. Thereby, in addition to the time to pass through the deodorizing filter 62, the air can be brought into contact with water also in the time to stay in the stay space 64a. At this time, the bottom surface of the deodorizing filter 62 has more water than the top surface of the deodorizing filter 62. Therefore, for example, compared with the case where air is passed from the upper side to the lower side with respect to the deodorizing filter 62, the contact time during which the sucked air comes into contact with water can be increased. Thereby, the deodorizing performance of the 1st deodorizing unit 41 can be improved.

  Further, by supplying water to the deodorizing filter 62 from above, water droplets WD adhere to the inner wall surface 64n forming the stay space 64a. Thereby, the contact probability of air and water can be raised by making the air which stays in the retention space 64a contact the water droplet WD adhering to the inner wall surface 64n. The deodorizing performance of the first deodorizing unit 41 can be further improved.

  Further, when air is passed from below to above with respect to the deodorizing filter 62, the staying space 64a is made wider than the upper space 64b. Thereby, air can be more easily retained in the retention space 64a, and the contact time between air and water can be further increased. And the stay of the air in the upper space 64b can be suppressed, and it can discharge | emit to the exterior of the casing 20 immediately. Thereby, the deodorizing performance of the 1st deodorizing unit 41 can be improved more.

  The air that has passed through the deodorizing filter 62 is rectified by the through holes 70 a of the deodorizing filter 62. Thereby, the retention of air in the upper space 64b can be further suppressed.

FIG. 7 is a cross-sectional view illustrating the first deodorizing unit.
FIG. 7 shows a cross section taken along line C1-C2 of FIG.
As shown in FIG. 7, the duct portion 64 has an introduction portion 64 c. The introduction part 64c guides the air sucked by the fan 61 to the staying space 64a. In the connection portion between the introduction portion 64c and the stay space 64a, the center CT1 in the width direction of the introduction portion 64c is shifted laterally with respect to the center CT2 in the width direction of the stay space 64a. The introduction part 64c extends, for example, in a tangential direction with respect to the stay space 64a.

  Thus, the center CT1 of the introduction part 64c is shifted from the center CT2 of the staying space 64a. Thereby, it is possible to make the air stay more easily in the stay space 64a. For example, as represented by an arrow line in FIG. 7, the air can be rotated along the inner side surface 64 s (a part of the inner wall surface 64 n) of the duct portion 64. Thereby, the contact time of air and water can be lengthened, and the deodorizing performance of the 1st deodorizing unit 41 can be improved more.

  A part of the inner side surface 64s of the duct portion 64 is curved in an arc shape. As a result, the air can be more easily rotated. When a sirocco fan is used as the fan 61, as indicated by the size of the arrow in FIG. 7, the wind is stronger on the outer peripheral side of the rotating rotor than on the inner peripheral side. In this case, the fan 61 is arranged so that the wind blown from the outer peripheral side of the rotor of the fan 61 follows the inner side surface 64 s of the duct portion 64. As a result, the air can be further easily rotated. The contact time between air and water can be made longer, and the deodorizing performance of the first deodorizing unit 41 can be further improved.

  In addition, as illustrated in FIG. 7, the duct portion 64 includes a first drain port 74a and a second drain port 74b. The first drain port 74 a allows the water sprayed from the spray unit 63 and dripped with the deodorizing filter 62 to flow into the drainage basin 80. That is, the duct portion 64 is connected to the drainage basin 80 through the first drain port 74a. The 2nd drainage port 74b is provided in the bottom part between the deodorizing filter 62 and the fan 61, and drains the water which goes to the fan 61 side outside. For example, the second drain port 74 b causes water directed toward the fan 61 to drip onto the base plate 24 and drain the water to the bowl portion 4 a of the toilet 4 via the base plate 24.

  The first drain port 74a is provided on the center side of the base plate 24 in the left-right direction. The second drain port 74b is provided on the opposite side to the first drain port 74a in the left-right direction. That is, the introduction part 64c is provided on the opposite side to the first drain port 74a in the left-right direction. Thereby, for example, the first drain port 74a and the drainage basin 80 can be easily connected. By providing the first drain port 74a toward the center side of the base plate 24 that drains into the bowl portion 4a, the water drained from the first deodorizing unit 41 can be more easily drained into the bowl portion 4a. .

FIG. 8 is a cross-sectional view illustrating the first deodorizing unit.
FIG. 8 shows a cross section taken along line D1-D2 of FIG.
As shown in FIGS. 6 and 8, the inner bottom surface 64d (a part of the inner wall surface 64n) of the duct portion 64 that receives water dropped from the deodorizing filter 62 is inclined downward toward the first drain port 74a. The inner bottom surface 64d is an inclined surface having a drainage gradient for draining water dripped from the deodorizing filter 62 to the first drainage port 74a. The opening end of the first drain port 74a is located below the opening end of the second drain port 74b. Thereby, the water dripped from the deodorizing filter 62 is usually discharged to the bowl portion 4a of the toilet 4 through the drainage basin 80 toward the first drain port 74a.

  When the water dripped from the deodorizing filter 62 unintentionally goes to the fan 61 side, the second drain port 74b drops water on the base plate 24 and suppresses the water from being applied to the fan 61. The second drain port 74b is provided as necessary and can be omitted.

  As shown in FIGS. 5 and 6, the lid 26 has a protrusion 27. The protrusion 27 extends toward the inside of the casing 20 in a state where the lid 26 is attached to the opening 20a. The protruding portion 27 has a tip when the lid portion 26 is attached in a state where the deodorizing filter 62 is positioned on the exhaust port 66 side from an appropriate fixing position (the position shown in FIGS. 5 and 6). By contacting the deodorizing filter 62, the deodorizing filter 62 is guided to an appropriate fixing position. That is, when the deodorizing filter 62 is attached to the near side, the protrusion 27 moves the deodorizing filter 62 to an appropriate fixing position by pushing the deodorizing filter 62 according to the attachment of the lid portion 26.

  The casing 20 further includes a sealing member 28. The sealing member 28 is provided between the exhaust port 66 and the lid portion 26 of the first deodorizing unit 41. For example, the sealing member 28 has an annular shape along the exhaust port 66 of the first deodorizing unit 41. The sealing member 28 has a sponge shape (porous shape). The sealing member 28 is sandwiched between the exhaust port 66 and the lid portion 26 and is elastically deformed, thereby filling a gap between the exhaust port 66 and the lid portion 26.

  The protruding portion 27 is located between the lower end portion 28b of the sealing member 28 and the spraying portion 63 in a state where the lid portion 26 is attached to the opening portion 20a. Thereby, it can suppress that the water sprayed from the spraying part 63 falls on the lower end part 28b of the sealing member 28. FIG.

FIG. 9A and FIG. 9B are a cross-sectional view and a front view showing the lid.
FIG. 9B is an enlarged front view showing a part of the lid portion 26.
Fig.9 (a) is sectional drawing showing the E1-E2 line cross section of FIG.9 (b).
As shown in FIG. 9A and FIG. 9B, the upper surface 27u of the protrusion 27 of the lid portion 26 is inclined downward in the direction toward the inside of the casing 20 (in this example, the front).

  Thereby, even when the water sprayed from the spray part 63 hits the projection part 27, the water applied to the projection part 27 can be drained appropriately. For example, water applied to the protrusion 27 can be dripped onto the base plate 24 to prevent water from being accidentally applied to the electrical components in the casing 20.

  Further, the upper surface 27u of the protrusion 27 is inclined downward toward the center in the width direction. Thereby, the water applied to the protruding portion 27 can be collected at the central portion in the width direction of the protruding portion 27 and drained more appropriately. In addition, the “width direction” is more specifically a direction toward the inside of the casing 20 of the protrusion 27 and a direction orthogonal to the vertical direction. In this example, the width direction is the left-right direction.

  Further, a notch 27 a is provided at the tip of the protrusion 27. Thereby, the water applied to the protrusion 27 can be drained more appropriately from the cutout 27a while appropriately guiding the deodorizing filter 62 to the fixed position.

FIG. 10A and FIG. 10B are a plan view and a cross-sectional view showing an enlarged part of the base plate.
FIG.10 (b) represents the F1-F2 line cross section of Fig.10 (a).
As shown in FIGS. 10A and 10B, the drainage basin 80 includes a casket body 82 and a lid portion 84.

  The heel body 82 has a concave shape with an upper opening. In this example, the heel body 82 is formed integrally with the base plate 24. In other words, the bag main body 82 is formed in the base plate 24 in a groove shape. For example, the bag main body 82 may be formed as a member different from the base plate 24 and attached to the base plate 24. The lid 84 closes the upper side of the heel body 82. The lid portion 84 closes the upper portion of the heel body 82 by, for example, fitting into the opening end above the heel body 82. Thus, a tubular drainage basin 80 is formed by the basin body 82 and the lid portion 84.

  The drainage basin 80 may be formed of two members as described above, or may be formed of a single tubular member. However, as described above, the drainage basin 80 can be easily formed by forming the drainage basin 80 with the basin body 82 and the lid portion 84. Furthermore, by forming the main body 82 integrally with the base plate 24, the number of parts can be reduced, and the drainage base 80 can be more easily formed. For the bag main body 82 (base plate 24) and the lid 84, for example, a hard resin material is used. Thereby, the elastic deformation of the drainage basin 80 in a normal use state is suppressed.

FIG. 11 is a partial cross-sectional view showing a part of the base plate and the nozzle unit.
As shown in FIG. 11, the nozzle unit 33 includes a support 90 that supports the cleaning nozzle 34. The support 90 has a protrusion 90a that protrudes laterally toward the first deodorizing unit 41 side. The protruding portion 90 a is provided above the lid portion 84 of the drainage basin 80 and presses the one end 84 a side of the lid portion 84. Thus, the one end 84 a side of the lid portion 84 is pressed by the nozzle unit 33.

FIG. 12 is a partial cross-sectional view showing a part of the base plate and the second deodorizing unit.
As shown in FIG. 12, the second deodorizing unit 42 is provided above the lid portion 84 of the drainage basin 80 and presses the other end 84 b side of the lid portion 84. The 2nd deodorizing unit 42 has the leaf | plate spring part 42c. The 2nd deodorizing unit 42 presses the other end 84b side of the cover part 84 with the elastic force of the leaf | plate spring part 42c.

  The second deodorizing unit 42 contacts the drainage basin 80 only at the portion of the leaf spring portion 42c. Thereby, the fine contact of the 2nd deodorizing unit 42 and the drainage basin 80 can be suppressed, for example. For example, it is possible to suppress the vibration accompanying the driving of the fan of the second deodorizing unit 42 from being transmitted to the drainage basin 80 and the generation of vibration noise in the drainage basin 80.

FIG. 13 is a cross-sectional view illustrating a base plate.
FIG. 13 shows a cross section taken along line G1-G2 of FIG.
As shown in FIG. 13, the drainage gradient θ1 of the drainage basin 80 is larger than the drainage gradient θ2 of the drainage groove 24a. The drainage gradient θ1 of the drainage basin 80 is, for example, about 5 ° (3 ° to 10 °). The drainage gradient θ2 of the drainage groove 24a is, for example, about 1 ° (0.5 ° to 2 °).

  The drainage from the first deodorizing unit 41 is periodically performed in the normal operation of the sanitary washing device 10. Therefore, the drainage gradient θ1 of the drainage basin 80 is relatively large. Thereby, the water drained from the 1st deodorizing unit 41 can be drained to the bowl part 4a etc. more reliably and quickly. Furthermore, it is possible to suppress water from remaining in the drainage basin 80.

  On the other hand, in a normal use state, the possibility of washing water leaking from the flow path opening / closing valve 50 is low. Therefore, the drainage gradient θ2 of the drainage groove 24a is relatively small. Thereby, for example, the storage space in the casing 20 can be suppressed from being pressed by the drainage gradient θ2 of the drainage groove 24a. Washing water leaked from the flow path opening / closing valve 50 can be appropriately drained to the bowl portion 4a or the like while ensuring a storage space in the casing 20 appropriately.

FIG. 14 is a cross-sectional view illustrating the first deodorizing unit.
FIG. 14 shows a cross section taken along line H1-H2 of FIG.
As illustrated in FIG. 14, the spray unit 63 includes a spray nozzle 100. The spray nozzle 100 is provided above the deodorizing filter 62 in the duct portion 64 and sprays water onto the deodorizing filter 62 from above. The spraying range of the spray nozzle 100 is wider than the upper surface 70 u of the filter body 70 of the deodorizing filter 62. Thereby, water can be supplied to the entire filter body 70. The spray angle α of the spray nozzle 100 is, for example, 110 ° (90 ° or more and 130 ° or less). Thereby, water can be appropriately supplied to the entire filter body 70 while suppressing wasteful spread of water.

  The spray part 63 arrange | positions the spray nozzle 100 above the edge part of the deodorizing filter 62, and sprays water toward diagonally downward. The spray part 63 arranges the spray nozzle 100 above the end of the deodorizing filter 62 on the exhaust port 66 side. Thereby, the spray part 63 sprays water in the direction opposite to the exhaust port 66.

  The upper surface 70u of the filter body 70 is, for example, a substantially rectangular shape (see FIG. 5). The upper surface 70u of the filter body 70 has a long shape on one side. The deodorizing filter 62 is attached in the duct portion 64 with one end in the longitudinal direction facing the exhaust port 66, and the spraying portion 63 sprays water along the longitudinal direction of the upper surface 70 u of the filter body 70. Thereby, when water is sprayed obliquely downward, water can be easily supplied to the entire filter body 70. The position of the spray nozzle 100 is not limited to the above, and may be any position where water can be appropriately supplied to the entire filter body 70. For example, the spraying unit 63 may spray water downward.

  The case part 72 of the deodorizing filter 62 has a water receiving part 72a. The water receiver 72 a is provided below the spray nozzle 100. The water receiver 72a has a concave shape that opens upward, and receives water dripped from the spray nozzle 100 after water stoppage. The water receiving portion 72a has an opening at the bottom, and drops the received water onto the inner bottom surface 64d of the duct portion 64 through the opening. The water receiving part 72a drains the water dripped from the spray nozzle 100 after the water stop to the outside of the casing 20 through the opening of the bottom part, the inner bottom face 64d of the duct part 64, the first drainage port 74a, and the drainage basin 80. To do. Thereby, the water receiving part 72a suppresses that the water dripped from the spray nozzle 100 after water stop goes to the exhaust port 66 side. The water receiving portion 72 a prevents water dripped from the spray nozzle 100 after water stoppage from leaking out of the casing 20 from the vent hole 26 a of the lid portion 26.

  Further, the water receiving portion 72a receives water scattered in the 180 ° direction from the spray port 100a of the spray nozzle 100. Thereby, for example, even when a foreign matter such as a scale is clogged in the spray port 100a and water is scattered in the 180 ° direction, the leakage of water from the vent hole 26a of the lid portion 26 to the outside of the casing 20 is suppressed. can do.

  The duct portion 64 includes a duct main body 110 having an opening 110 a on the upper side, and a lid portion 112 that closes the opening 110 a of the duct main body 110. In addition, the duct part 64 does not need to be formed by two members, and may be formed by one substantially cylindrical member, or may be formed by combining three or more members.

  The duct body 110 has a ceiling surface 110 c that covers the upper side of the deodorizing filter 62 on the exhaust port 66 side. The lid portion 112 has a ceiling surface 112 c that covers the top of the deodorizing filter 62. The ceiling surface 112 c of the lid part 112 is inclined downward toward the spraying direction of the spraying part 63. In the following, the spray direction of the spray unit 63 (the direction in which the spray port 100a faces) is expressed as “front”. The ceiling surface 112c of the lid portion 112 is inclined downward toward the front.

  The duct main body 110 has a first diffusion suppression part 121. The first diffusion suppression unit 121 extends downward from the ceiling surface 110 c of the duct body 110 and suppresses the water sprayed from the spray unit 63 from spreading outside the deodorizing filter 62.

  The 1st spreading | diffusion suppression part 121 is arrange | positioned in the position which overlaps with the deodorizing filter 62 in an up-down direction. The first diffusion suppression unit 121 is disposed in the vicinity of the spray unit 63. The first diffusion suppression unit 121 has a facing surface 121 a that extends in a direction orthogonal to the spraying direction and the vertical direction of the spraying unit 63 and faces the spray nozzle 100. The first diffusion suppression unit 121 applies a part of the water sprayed from the spray unit 63 to the facing surface 121a and drops the water downward. Thereby, for example, water that attempts to pass above the deodorizing filter 62 can be supplied to the deodorizing filter 62. The first diffusion suppression unit 121 suppresses the water sprayed from the spray unit 63 from spreading forward than the deodorizing filter 62.

  The facing surface 121 a of the first diffusion suppressing unit 121 is inclined downward toward the spraying direction of the spraying unit 63. That is, the facing surface 121a is inclined downward toward the front. Thereby, it is possible to suppress the water that hits the facing surface 121 a of the first diffusion suppression unit 121 from bouncing back to the outside of the deodorizing filter 62. It can suppress that the water which hit the opposing surface 121a bounces back rather than the deodorizing filter 62. FIG. Therefore, water can be supplied to the deodorizing filter 62 more reliably.

  Further, by tilting the facing surface 121a downward, for example, even when the first diffusion suppression unit 121 is provided, the first diffusion suppression unit 121 is prevented from obstructing air passing through the duct portion 64. can do.

  The lid part 112 has a second diffusion suppression part 122. The second diffusion suppression unit 122 extends downward from the ceiling surface 112 c of the lid portion 112 and suppresses the water sprayed from the spray unit 63 from spreading outside the deodorizing filter 62.

  The second diffusion suppression unit 122 extends in a direction orthogonal to the spraying direction and the vertical direction of the spraying unit 63. In other words, the second diffusion suppression unit 122 extends laterally with respect to the spray direction of the spray unit 63. The second diffusion suppression unit 122 has, for example, a plate shape that extends laterally.

  The second diffusion suppression unit 122 closes the space between the front end of the deodorizing filter 62 and the ceiling surface 112 c of the lid portion 112. Thereby, the second diffusion suppression unit 122 suppresses the water sprayed from the spray unit 63 from spreading forward than the deodorizing filter 62.

  Thus, by providing the 2nd diffusion suppression part 122, it can suppress more that the water sprayed from the spray part 63 spreads ahead rather than the deodorizing filter 62. FIG. More specifically, the front end of the deodorizing filter 62 is an end portion on the opposite side to the end portion on the side where the spray nozzle 100 is provided in the deodorizing filter 62.

  The second diffusion suppression unit 122 is disposed at a position that does not overlap with the deodorizing filter 62 in the vertical direction. The second diffusion suppression unit 122 is located outside the deodorizing filter 62. Also in this case, the spread of water can be suppressed by, for example, reflecting water droplets by the second diffusion suppression unit 122. As described above, the diffusion suppressing unit does not necessarily have to be disposed at a position overlapping the deodorizing filter 62.

FIG. 15 is a cross-sectional view illustrating the first deodorizing unit.
FIG. 15 shows a cross section taken along line I1-I2 of FIG.
As illustrated in FIG. 15, the lid 112 further includes a third diffusion suppression unit 123 and a fourth diffusion suppression unit 124. The third diffusion suppression unit 123 and the fourth diffusion suppression unit 124 extend downward from the ceiling surface 112 c of the lid 112, and suppress the water sprayed from the spray unit 63 from spreading outside the deodorizing filter 62.

  The third diffusion suppression unit 123 and the fourth diffusion suppression unit 124 extend in the spray direction of the spray unit 63. In other words, the third diffusion suppression unit 123 and the fourth diffusion suppression unit 124 extend in the front-rear direction with respect to the spraying direction of the spraying unit 63. The third diffusion suppression unit 123 and the fourth diffusion suppression unit 124 are, for example, plate shapes extending in the front-rear direction.

  The third diffusion suppression unit 123 closes the space between one side end of the deodorizing filter 62 and the ceiling surface 112 c of the lid portion 112. The fourth diffusion suppression unit 124 blocks between the other side end of the deodorizing filter 62 and the ceiling surface 112 c of the lid portion 112. Thereby, the 3rd diffusion suppression part 123 and the 4th diffusion suppression part 124 suppress that the water sprayed from the spray part 63 spreads to the side rather than the deodorizing filter 62. FIG.

  Thus, the 2nd diffusion suppression part 122, the 3rd diffusion suppression part 123, and the 4th diffusion suppression part 124 are provided, and the front and both sides of the deodorizing filter 62 are enclosed. Thereby, it can suppress more reliably that the water sprayed from the spraying part 63 spreads outside the deodorizing filter 62. The water sprayed from the spray part 63 can be more reliably supplied to the deodorizing filter 62, and generation | occurrence | production of useless water can be suppressed more reliably.

  The 3rd spreading | diffusion suppression part 123 and the 4th spreading | diffusion suppression part 124 are arrange | positioned in the position which does not overlap with the deodorizing filter 62 in an up-down direction. The third diffusion suppression unit 123 and the fourth diffusion suppression unit 124 are located outside the deodorizing filter 62. Each position of the 3rd diffusion suppression part 123 and the 4th diffusion suppression part 124 may be the arbitrary positions which can control the spread to the side of the water sprayed from spray part 63.

FIG. 16 is a cross-sectional view illustrating a modification of the first deodorizing unit.
As illustrated in FIG. 16, the second diffusion suppression unit 122 may be disposed at a position overlapping the deodorizing filter 62 in the vertical direction. In other words, the second diffusion suppression unit 122 may be disposed inside the deodorizing filter 62.

  In this example, the second diffusion suppression unit 122 is provided on the front end portion of the filter body 70. Thereby, the water which hit the 2nd spreading | diffusion suppression part 122 can be more reliably supplied to the deodorizing filter 62, suppressing the spreading to the front of the water sprayed from the spray part 63. FIG.

  For example, both the second diffusion suppression unit 122 disposed outside the deodorizing filter 62 and the second diffusion suppression unit 122 disposed inside the deodorizing filter 62 may be provided in the lid 112. Thereby, it can suppress more reliably that the water sprayed from the spray part 63 spreads ahead rather than the deodorizing filter 62. FIG.

FIG. 17 is a cross-sectional view illustrating a modification of the first deodorizing unit.
As illustrated in FIG. 17, the third diffusion suppression unit 123 and the fourth diffusion suppression unit 124 may be disposed at a position overlapping the deodorization filter 62 in the vertical direction. In other words, the third diffusion suppression unit 123 and the fourth diffusion suppression unit 124 may be disposed inside the deodorizing filter 62.

  In this example, the third diffusion suppression unit 123 is provided on one side end of the filter body 70. The fourth diffusion suppression unit 124 is provided on the other side end of the filter body 70. Thereby, the water which hit the 3rd spreading | diffusion suppression part 123 and the 4th spreading | diffusion suppression part 124 is supplied to the deodorizing filter 62 more reliably, suppressing the spread to the side of the water sprayed from the spraying part 63. FIG. be able to.

  For example, the third diffusion suppression unit 123 and the fourth diffusion suppression unit 124 disposed outside the deodorization filter 62, the third diffusion suppression unit 123 and the fourth diffusion suppression unit 124 disposed inside the deodorization filter 62, Each of these may be provided on the lid 112. Thereby, it can suppress more reliably that the water sprayed from the spray part 63 spreads to the side rather than the deodorizing filter 62. FIG.

  As described above, in the sanitary washing device 10 according to the present embodiment, the spread of water is suppressed by the first diffusion suppression unit 121 to the fourth diffusion suppression unit 124, and the entire deodorization filter 62 is efficiently configured with a simple configuration. We can supply water well. In the sanitary washing device 10 including the first deodorizing unit 41, generation of useless water can be suppressed.

  The first diffusion suppression unit 121 to the fourth diffusion suppression unit 124 are not necessarily provided. The 1st deodorizing unit 41 should just have at least 1 of the 1st spreading | diffusion suppression part 121-the 4th spreading | diffusion suppression part 124. FIG. By providing the first diffusion suppression unit 121 to the fourth diffusion suppression unit 124 in the first deodorizing unit 41, the spread of water can be suppressed more reliably. Generation of wasted water can be more reliably suppressed.

  In the sanitary washing device 10, the first diffusion suppression unit 121 is disposed at a position overlapping the deodorizing filter 62 in the vertical direction. Thereby, the water which hit the 1st diffusion suppression part 121 can be reliably supplied to the deodorizing filter 62. Generation of wasted water can be further suppressed.

  Moreover, in the sanitary washing apparatus 10, the spraying part 63 arrange | positions the spray nozzle 100 above the edge part of the deodorizing filter 62, and sprays water toward diagonally downward. Thereby, the position of the spray nozzle 100 can be made low, ensuring the distance between the deodorizing filter 62 and the spray nozzle 100 required for spraying compared with the case where water is jetted right below. The 1st deodorizing unit 41 can be reduced in size.

  In the sanitary washing device 10, the facing surface 121 a of the first diffusion suppression unit 121 is inclined downward toward the spraying direction of the spraying unit 63. Thereby, it is possible to suppress the water hitting the first diffusion suppression unit 121 from bouncing back to the outside of the deodorizing filter 62, and to supply water to the deodorizing filter 62 more reliably, thereby further suppressing generation of wasted water. can do.

  In the sanitary washing device 10, the ceiling surface 112 c is inclined downward toward the spray direction of the spray unit 63. Thereby, water can be more reliably supplied to the part far from the spray nozzle 100 of the deodorizing filter 62 by transmitting water to the ceiling surface 112c. That is, water can be more reliably supplied to the front end portion of the deodorizing filter 62.

  Moreover, in the sanitary washing apparatus 10, the case part 72 of the deodorizing filter 62 has the water receiving part 72a. Thereby, the water dripped from the spray nozzle 100 after water stop can be drained more reliably. The water dripped from the spray nozzle 100 after the water stop can be prevented from unexpectedly leaking out of the casing 20 from the vent hole 26a of the lid portion 26.

  Further, in the sanitary washing device 10, the spray unit 63 sprays water in the direction opposite to the exhaust port 66. Thereby, it can suppress that the water sprayed from the spray part 63 will be discharged | emitted outside the casing 20. FIG.
