The sensor 32 can detect the presence of the user through the door of the toilet room. That is, the human body detection sensor 32 can detect the user before entering the toilet room.

The control unit 42 controls the operations of the cleaning water supply unit 28, the multifunctional unit 30, the human body detection sensor 32, the cleaning nozzle 34, the nozzle cleaning chamber 36, the spray nozzle 38, and the deodorizing unit 40, respectively. The control unit 42 controls the operation of each unit in response to an operation instruction input from the operation unit 44, for example. The operation unit 44 may be provided in the main body unit 12 or may be provided separately from the main body unit 12. The operation unit 44 may be a so-called remote controller. The communication between the control unit 42 and the operation unit 44 may be wired or wireless.

The wash water supply unit 28 and the multifunctional unit 30 form a part of the water channel 46 that supplies the wash water to the wash nozzle 34. The water channel 46 reaches the cleaning nozzle 34 from a water supply source such as a water supply or a water storage tank. The washing water supply unit 28 and the multifunctional unit 30 send the washing water supplied from the water supply source to the washing nozzle 34.

The wash water supply unit 28 includes a flow path on-off valve 50 and a heat exchanger 51. The flow path on-off valve 50 is an electromagnetic valve that can be opened and closed, and controls the supply of cleaning water based on a command from the control unit 42. The flow path on-off valve 50 switches between supplying and stopping the washing water supplied from the water supply source.

The heat exchanger 51 is provided downstream of the flow path on-off valve 50. The heat exchanger 51 heats the washing water supplied from the water supply source by a heater to raise the temperature to, for example, a specified temperature.

The electrolytic cell 52 is provided downstream of the heat exchanger 51 via the flexible tube T11. The electrolytic cell 52 has a pair of electrodes, and electrolyzes the washing water (tap water) flowing between the electrodes based on the energization control signal transmitted from the control unit 42. The electrolytic cell 52 electrolyzes chloride ions contained in the washing water to generate a liquid containing hypochlorous acid (HClO) (hereinafter referred to as “functional water”).

The vacuum breaker 53 is provided downstream of the electrolytic cell 52. The vacuum breaker 53 has, for example, a flow path for flowing water, an intake port for taking in air into the flow path, and a valve mechanism for opening and closing the intake port. The valve mechanism closes the intake port when water is flowing in the flow path, and opens the intake port when the flow of water is stopped to take in air into the flow path. That is, the vacuum breaker 53 takes in air into the water channel 46 when there is no water flow in the water channel 46. For the valve mechanism, for example, a float valve is used.

The vacuum breaker 53 takes in air into the water channel 46 as described above, thereby promoting drainage of a portion of the water channel 46 downstream of the vacuum breaker 53, for example. The vacuum breaker 53 promotes, for example, drainage of the cleaning nozzle 34. In this way, the vacuum breaker 53 drains the water in the cleaning nozzle 34 and takes in air into the cleaning nozzle 34, so that, for example, the cleaning water in the cleaning nozzle 34 and the sewage accumulated in the bowl portion 4a can be removed. Prevents backflow to the water supply source (clean water) side.

The electromagnetic pump 54 is provided downstream of the vacuum breaker 53. The electromagnetic pump 54 pulsates or accelerates the flow of water in the water channel 46, and pulsates the water discharged from the cleaning nozzle 34. That is, the electromagnetic pump 54 changes the flow state of the water flowing in the water channel 46. The electromagnetic pump 54 is connected to the control unit 42. The electromagnetic pump 54 changes the flow state of water based on the control by the control unit 42. As used herein, the term "pulsation" refers to the fluctuation of pressure in the water channel 46 caused by the electromagnetic pump 54. The electromagnetic pump 54 fluctuates the pressure of water in the water channel 46.

The cleaning nozzle 34 has a water discharge unit 35. The water spouting unit 35 has, for example, a buttocks washing water spouting hole 35a, a buttocks soft water spouting hole 35b, and a bidet washing water spouting hole 35c.

Further, the cleaning nozzle 34 has a buttocks cleaning flow path FC1, a buttocks soft flow path FC2, a bidet cleaning flow path FC3, and a wide bidet cleaning flow path FC4. The buttocks cleaning flow path FC1 is connected to the buttocks cleaning water discharge hole 35a, and supplies cleaning water or functional water to the buttocks cleaning water discharge hole 35a. The buttocks soft flow path FC2 is connected to the buttocks soft water discharge hole 35b, and supplies washing water or functional water to the buttocks soft water discharge hole 35b. The bidet cleaning flow path FC3 and the wide bidet cleaning flow path 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 hole and the flow path of the cleaning nozzle 34 are not limited to this. The number of spout holes does not have to match the number of flow paths as described above, or may be the same as the number of flow paths.

The cleaning water or functional water sent to the cleaning nozzle 34 is discharged upward from the water discharge unit 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. Further, in the cleaning nozzle 34, the bidet cleaning is performed by supplying the cleaning water from the bidet cleaning flow path FC3 to the bidet cleaning water discharge hole 35c, and the cleaning water is supplied from the wide bidet cleaning flow path FC4 to the bidet cleaning water discharge hole 35c. By doing so, wide bidet cleaning is performed. The functional water is used for cleaning 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 has four flow paths FC1 to FC4, and is configured to be capable of discharging cleaning water or 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 sets the destination of the cleaning water or the functional water supplied via the electromagnetic pump 54 to the tail cleaning flow path FC1, the tail soft flow path FC2, the bidet cleaning flow path FC3, and the wide bidet cleaning flow path. Switch to any of FC4, nozzle cleaning chamber 36, spray nozzle 38, and deodorizing unit 40. Further, the flow control / flow path switching valve 55 changes the discharge flow rate of the cleaning water discharged from the water discharge holes 35a to 35c of the cleaning nozzle 34.

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

The nozzle motor 37 supplies a driving force to the cleaning nozzle 34 to advance the cleaning nozzle 34 into the bowl portion 4a of the toilet bowl 4 or retract it into the casing 20. The nozzle motor 37 advances and retreats the cleaning nozzle 34 based on a command from the control unit 42. The nozzle motor 37 may be included in the multifunctional unit 30, for example.

The spray nozzle 38 is provided downstream of the flow control / flow path switching valve 55 via the flexible tube T26 (see FIGS. 2 and 4). The spray nozzle 38 sprays wash water or functional water on the surface of the bowl portion 4a of the toilet bowl 4. The spray nozzle 38 may be provided inside the casing 20 or may be attached to the outside of the casing 20.

For example, the control unit 42 sprays water droplets from the spray nozzle 38 onto the surface of the bowl portion 4a of the toilet bowl 4 in response to the detection of the user entering the room by the human body detection sensor 32. That is, the control unit 42 wets the surface of the bowl portion 4a of the toilet bowl 4 with water droplets before the user uses the toilet bowl 4. Thereby, the filth adhering to the surface of the bowl portion 4a can be reduced.

Further, the control unit 42 receives, for example, from the spray nozzle 38 to the bowl portion of the toilet bowl 4 when a predetermined time (for example, 90 seconds later) has elapsed since the human body detection sensor 32 stopped detecting the user in the toilet room. Spray functional water on the surface of 4a. That is, the control unit 42 wets the surface of the bowl portion 4a with functional water (hypochlorous acid water) after the user flushes the filth and finishes using the toilet bowl 4. As a result, it is possible to prevent the bacteria that cause the malodor from increasing in the bowl portion 4a. It is possible to suppress the release of a foul odor from the toilet bowl 4.

The deodorizing unit 40 sucks in the air in the toilet room. The air in the toilet room mainly refers to the air outside the toilet bowl 4 (air other than the air inside the bowl portion 4a). The deodorizing unit 40 collects or decomposes malodorous components and the like contained in the sucked air. The "odor component" is, for example, a component such as ammonia or trimethylamine. The deodorizing unit 40 discharges air that has collected or decomposed malodorous components to the outside (toilet room) of the casing 20.

The deodorizing unit 40 includes a dust collecting filter 60, a fan (blower) 61, a deodorizing filter 62, a spraying unit 63, a water receiving unit 64, an intake port 65, and an exhaust port 66.

The fan 61 sucks the air in the toilet room from the intake port 65, and discharges the sucked air from the exhaust port 66 to the toilet room. The dust collection filter 60 is provided between the intake port 65 and the fan 61, and suppresses dust and dirt contained in the sucked air from being sent to the fan 61.

The deodorizing filter 62 is provided between the fan 61 and the exhaust port 66. The spray portion 63 is provided above the deodorizing filter 62. Based on the control of the control unit 42, the spray unit 63 sprays the cleaning water or the functional water supplied from the flow control / flow path switching valve 55 from above the deodorizing filter 62 toward the deodorizing filter 62.

The deodorizing filter 62 has, for example, a porous structure and holds the washing water or the functional water sprayed from the spraying unit 63. The water receiving portion 64 is provided below the deodorizing filter 62 and receives the water dropped from the deodorizing filter 62.

When the fan 61 is activated, the air in the toilet room sucked from the intake port 65 passes through the deodorizing filter 62. When air passes through the deodorizing filter 62 while the deodorizing filter 62 retains moisture, malodorous components and the like 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 water retained in the deodorizing filter 62. This makes it possible to reduce malodorous components and the like contained in the air.

The air with reduced malodorous components is discharged from the exhaust port 66 to the toilet room. In this way, the deodorizing unit 40 can collect or decompose malodorous components and the like that are resident in the toilet room. Therefore, when the user enters the toilet room, the possibility of inhaling the odor due to the malodorous component resident in the toilet room is reduced, and the user can comfortably use the toilet room.

The control unit 42 stops the operation of the fan 61, for example, during a time period when the user's toilet device 2 is infrequently used. Then, the control unit 42 operates the fan 61 and periodically operates the spray unit 63 to cause the deodorizing filter 62 to retain water during the time when the user's toilet device 2 is frequently used.

As a result, it is possible to remove the odor resident in the toilet room during the time when the user is likely to enter the toilet room. Therefore, it is possible to suppress the user from feeling uncomfortable by inhaling the odor that is resident in the toilet room.

FIG. 3 is an explanatory diagram showing an electromagnetic pump.
As shown in FIG. 3, the electromagnetic pump 54 includes a pump 70 (first electric motor) and an accumulator 71. The pump 70 is provided on the path of the water channel 46 and gives pulsation to the water flowing toward the cleaning nozzle 34. The accumulator 71 is provided on the upstream side of the pump 70 on the path of the water channel 46, and suppresses pressure fluctuations in the water channel 46 on the upstream side of the pump 70.

The pump 70 has a cylinder 72, a plunger 73, and a coil 74. The cylinder 72 has a substantially tubular shape. An opening 72a is provided at one end of the cylinder 72. An opening 72b is provided at the other end of the cylinder 72. The opening 72a is connected to the vacuum breaker 53. The opening 72b is connected to the flow control / flow path switching valve 55. The cylinder 72 allows the water supplied from the vacuum breaker 53 to flow to the flow control / flow path switching valve 55. That is, the cylinder 72 forms a part of the water channel 46. In this example, the cylinder 72 is a pipeline bent in a substantially L shape. The shape of the cylinder 72 is not limited to this, and may be a linear shape or the like.

The plunger 73 is provided inside the cylinder 72 so as to be able to advance and retreat, and moves back and forth between the position on the upstream side (opening 72a side) and the position on the downstream side (opening 72b side). FIG. 3 illustrates a state in which the plunger 73 is located on the upstream side. The plunger 73 has a tubular shape. Further, a check valve (not shown) is provided inside the tubular plunger 73.

When the plunger 73 moves from the upstream position to the downstream position, the check valve closes the open end of the tubular plunger 73. As a result, when the plunger 73 moves from the upstream position to the downstream position, the water in the cylinder 72 is sent to the downstream side. Therefore, when the plunger 73 moves from the position on the upstream side to the position on the downstream side, the pressure in the water channel 46 downstream of the electromagnetic pump 54 increases.

On the other hand, when the plunger 73 moves from the downstream position to the upstream position, the check valve opens the open end of the tubular plunger 73. As a result, when the plunger 73 moves from the position on the downstream side to the position on the upstream side, water flows into the portion downstream of the plunger 73 in the cylinder 72. In this way, the check valve regulates only the inflow of water from the downstream side to the upstream side in the plunger 73. Therefore, when the plunger 73 is stopped, water can flow from the opening 72a to the opening 72b via the check valve.

The coil 74 controls the forward / backward movement of the plunger 73 by excitation. When the coil 74 is not excited, the plunger 73 is held in the upstream position by the elastic force of the spring 75. When the coil 74 is excited, the plunger 73 moves to a position on the downstream side against the elastic force of the spring 75. Then, when the excitation of the coil 74 is stopped, the plunger 73 returns to the upstream position again due to the elastic force of the spring 75. At this time, the elastic force of the spring 76 buffers the return operation of the plunger 73.

In this way, the pump 70 can give pulsation to the flow of water in the water channel 46 by controlling the excitation of the coil 74. The coil 74 is electrically connected to the control unit 42. The excitation of the coil 74 is controlled by the control unit 42. The configuration of the pump 70 is not limited to the above, and may be any configuration capable of giving pulsation to the water flowing through the water channel 46 toward the cleaning nozzle 34 (downstream side).

The accumulator 71 has a first adjusting chamber 71a, a second adjusting chamber 71b, and a damper 71c. The first adjusting chamber 71a is connected to the cylinder 72 upstream of the plunger 73 via the pipeline 71d. As a result, water flows into the first adjusting chamber 71a and the pipeline 71d. The second adjusting chamber 71b is filled with a gas such as air or nitrogen. The damper 71c partitions the first adjusting chamber 71a and the second adjusting chamber 71b. For the damper 71c, for example, an elastic material such as rubber is used. In other words, the damper 71c is a rubber film.

When the plunger 73 of the pump 70 returns from the downstream position to the upstream position, the accumulator 71 accommodates the water flowing toward the upstream side in the first adjusting chamber 71a. At this time, the accumulator 71 bends the damper 71c toward the second adjusting chamber 71b and compresses the gas in the second adjusting chamber 71b. In other words, pressure is accumulated in the second adjusting chamber 71b by compressing the gas in the second adjusting chamber 71b.

Then, when the plunger 73 of the pump 70 moves from the upstream position to the downstream position, the accumulator 71 sends the water contained in the first adjusting chamber 71a into the cylinder 72 (pump 70 side), and the accumulator 71 is the first 2 The pressure accumulated in the adjusting chamber 71b is released.

As described above, the accumulator 71 absorbs or buffers the pulsation by appropriately acting the damper 71c according to the pressure of the water pulsated by the pump 70. As a result, the accumulator 71 suppresses the transmission of the pulsation of water given by the pump 70 to the upstream side. In other words, the accumulator 71 absorbs the pressure fluctuation applied to the upstream side when the plunger 73 returns from the downstream position to the upstream side position. As a result, for example, it is possible to suppress the vibration of the flexible hose forming a part of the water channel 46 and the generation of abnormal noise.

In this example, the accumulator 71 is provided substantially integrally with the pump 70. The accumulator 71 may be provided separately from the pump 70. The accumulator 71 may be connected at least upstream of the pulsating portion of the pump 70 on the path of the water channel 46. The accumulator 71 may include, for example, a so-called air chamber that does not include a damper 71c or the like.

FIG. 4 is an explanatory diagram showing a flow control / flow path switching valve.
As shown in FIG. 4, the flow control / flow path switching valve 55 includes a fixed disc (stator) 80, a movable disc (rotor) 82, a housing 84, and a drive mechanism 86 (second motor). ..

The fixed disk 80 has, for example, a disk shape and has a front surface 80a (a surface facing the upstream side) and a back surface 80b (a surface facing the downstream side) opposite the front surface 80a. The fixed disk 80 has a plurality of ports corresponding to each of the buttocks cleaning flow path FC1, the buttocks soft flow path FC2, the bidet cleaning flow path FC3, the wide bidet cleaning flow path FC4, the nozzle cleaning chamber 36, the spray nozzle 38, and the deodorizing unit 40.

The movable disc 82 abuts on the front surface 80a of the fixed disc 80. The movable disc 82 slides and rotates on the front surface 80a with a direction orthogonal to the front surface 80a as an axis (hereinafter, referred to as a rotation axis RA). The movable disc 82 has an opening corresponding to one port of the fixed disc 80. For example, when the opening of the movable disk 82 overlaps one port of the fixed disk 80, another port of the fixed disk 80 is blocked by the movable disk 82. As a result, water can pass through only one port that overlaps with the opening of the movable disk 82.

The flow control / flow path switching valve 55 selectively switches the ports through which water can pass by rotating the movable disk 82. As a result, any one of the tail cleaning flow path FC1, the tail cleaning flow path FC2, the bidet cleaning flow path FC3, the wide bidet cleaning flow path FC4, the nozzle cleaning chamber 36, the spray nozzle 38, and the deodorizing unit 40, depending on the port to be selected. , Washing water or functional water can be selectively supplied.

The drive mechanism 86 has an electric motor such as a motor or a solenoid, and rotates the movable disk 82 by supplying a driving force to the movable disk 82. The drive mechanism 86 is connected to the control unit 42 and rotates the movable disk 82 under the control of the control unit 42. The control unit 42 drives the drive mechanism 86 to rotate the movable disk 82, and by selecting either of the ports of the fixed disk 80, the destination of the washing water or the functional water is switched. The drive mechanism 86 may be any mechanism capable of rotating the movable disk 82 without causing water leakage.

FIG. 5 is a plan view showing a part of the sanitary cleaning device according to the embodiment.

The electromagnetic pump 54 is rigidly coupled to the flow control / flow path switching valve 55. In this way, each part of the multifunctional unit 30 is rigidly connected to each other and is substantially integrated.

Here, the rigid body connection is, for example, a fixed connection between substantially rigid bodies to each other. A rigid body is, for example, a body whose deformation is negligible when a force is applied. For example, it is molded from a metal material (for example, iron, aluminum, stainless steel, etc.) or a resin material (for example, polypropylene, polystyrene, polycarbonate, acrylic resin, ABS resin, etc.).

The multifunctional unit 30 has a first functional unit having a first electric motor and a second functional unit rigidly coupled to the first functional unit. The first functional unit is, for example, an electromagnetic pump 54. The first electric motor is, for example, a pump 70.

In this example, the number of the second vibration absorbers 102 is three. As a result, the support 25 can be supported at three points, and the support 25 can be supported more appropriately. In this way, at least three second vibration spheres 102 are provided, and the number of second vibration absorbers 102 is set to be equal to or greater than the number of first vibration absorbers 101. As a result, the support 25 can be attached to the casing 20 more reliably, and the transmission of vibration can be further suppressed. The number of the second vibration absorbers 102 is not limited to three, and may be any number that can appropriately support the support 25. Further, the number of the second vibration absorbers 102 may be the same as or different from the number of the first vibration absorbers 101.

Each second vibration absorber 102 is arranged so as to surround the center of gravity GC of the multifunctional unit 30, for example (see FIG. 9B). Each second vibration absorber 102 is arranged so as to surround the center of gravity GC of the multifunctional unit 30 when, for example, the center of gravity GC of each second vibration absorber 102 and the multifunctional unit 30 is projected on a horizontal plane.

In this way, the multifunctional unit 30 is attached to the base plate 24 via the support 25, the first vibration absorber 101, and the second vibration absorber 102. The multifunctional unit 30 is attached to the support 25 and the base plate 24 only via the first vibration absorber 101.

The elastic modulus of the first vibration absorber 101 and the second vibration absorber 102 is smaller than the elastic modulus of each part (rigid body) of the multifunctional unit 30. In other words, the rigid body has a higher elastic modulus than the first vibration absorber 101 and the second vibration absorber 102.

The first vibration absorber 101 and the second vibration absorber 102 are, for example, anti-vibration rubber. The first vibration absorber 101 and the second vibration absorber 102 may be, for example, a spring, an air suspension mechanism, an oil suspension mechanism, or the like. The first vibration absorber 101 and the second vibration absorber 102 may be any member capable of suppressing the transmission of vibration.

The first vibration absorber 101 is separated from the second vibration absorber 102. A support 25 is interposed between the first vibration absorber 101 and the second vibration absorber 102, and the first vibration absorber 101 does not come into direct contact with the second vibration absorber 102. In other words, the first vibration absorber 101 is cut off from the second vibration absorber 102 by the support 25.

Further, the first vibration absorber 101 is arranged so as to be offset in the horizontal direction with respect to the second vibration absorber 102. The first vibration absorber 101 does not line up with the second vibration absorber 102 in the vertical direction.

The support 25 has a drainage channel 25a for draining the washing water or the functional water leaked from the vacuum breaker 53 of the multifunctional unit 30 or another seal portion. An opening 25b is provided at the end of the drainage channel 25a. The drainage channel 25a guides the washing water or the functional water leaked from the multifunctional unit 30 to the opening 25b and drops the washing water or the functional water from the opening 25b onto the base plate 24. The washing water or functional water dropped on the base plate 24 is drained to the bowl portion 4a of the toilet bowl 4 via the base plate 24. As a result, even when the washing water or the functional water leaks from the multifunctional unit 30, the leaked washing water or the functional water can be appropriately drained to the bowl portion 4a. It is possible to prevent water from splashing on the electronic parts and the like in the casing 20.

Further, in the multifunctional unit 30, the drive mechanism 86 of the heaviest flow control / flow path switching valve 55 is located at the lowermost position. The heaviest component in the multifunction unit 30 is located at the bottom.

As a result, the position CGP of the center of gravity of the multifunctional unit 30 in the height direction can be lowered. The center of gravity position CGP in the height direction of the multifunction unit 30 is located below the center position CP1 in the height direction of the multifunction unit 30.

As described above, in the sanitary cleaning device 10 according to the present embodiment, by rigidly coupling each part of the multifunctional unit 30, the weight around the pump 70 and the drive mechanism 86, which are vibration sources, is increased. , Vibration transmission can be suppressed.

It is located between the washing water supply unit 28 (upstream function unit) and the water discharge unit 35 (downstream function unit) that are not supported by 20. Then, the multifunctional unit 30 is connected to the washing water supply unit 28 and the water discharge unit 35 via flexible tubes T11 and T21 to T27. As a result, the vibration of the pump 70 and the drive mechanism 86 is transmitted to the washing water supply unit 28 and the water discharge unit 35 which are not supported by the casing 20 via the first vibration absorber 101 and the second vibration absorber 102. Can be absorbed. As a result, the vibration of the motor can be further suppressed.

Further, in the sanitary cleaning device 10, the first vibration absorber 101 is separated from the second vibration absorber 102. Thereby, the transmission of vibration can be further suppressed. The vibration and vibration noise of the toilet seat 14 can be further suppressed.

Further, in the sanitary cleaning device 10, the first vibration absorber 101 is offset in the horizontal direction with respect to the second vibration absorber 102. Thereby, the transmission of vibration can be further suppressed. The vibration and vibration noise of the toilet seat 14 can be further suppressed.

Further, in the sanitary cleaning device 10, at least three second vibration absorbers 102 are provided, and the number of the second vibration absorbers 102 is equal to or greater than the number of the first vibration absorbers 101. As a result, the support 25 can be attached to the casing 20 more reliably, and the transmission of vibration can be further suppressed.

Further, in the sanitary cleaning device 10, at least three second vibration absorbers 102 are arranged so as to surround the center of gravity GC of the multifunctional unit 30. As a result, the multifunctional unit 30 can be attached to the casing 20 more stably, and the transmission of vibration can be further suppressed.

Further, in the sanitary cleaning device 10, the flow control / flow path switching valve 55 (second functional unit) has a drive mechanism 86 (second motor). As described above, even in the multifunctional unit 30 including a larger number of vibration sources, the transmission of vibration can be appropriately suppressed.

Thereby, the transmission of vibration can be further suppressed. The vibration and vibration noise of the toilet seat 14 can be further suppressed.

Further, in the sanitary cleaning device 10, the center position CP2 in the height direction of the pump 70 (first electric motor) is located below the center position CP1 in the height direction of the multifunction unit 30. In this way, by arranging the center position CP2 of the pump 70, which is a relatively heavy object, below the center position CP1 of the multifunction unit 30, it becomes easy to lower the center of gravity position CGP of the multifunction unit 30 in the height direction. be able to. The center of gravity position CGP of the multifunctional unit 30 can be made lower, and the transmission of vibration can be further suppressed.

Further, in the sanitary cleaning device 10, the multifunctional unit 30 constitutes a part of the water channel 46 for supplying the cleaning water to the cleaning nozzle 34, and the support 25 drains the cleaning water leaked from the multifunctional unit 30. It has a drainage channel 25a. As a result, the washing water leaked from the multifunctional unit 30 can be appropriately drained.

9 (a) and 9 (b) are a plan view and a bottom view showing a modified example of the first vibration absorber and the second vibration absorber.
As shown in FIGS. 9A and 9B, in this example, the number of the first vibration absorbers 101 is three, and the number of the second vibration absorbers 102 is four. In this example, the number of the second vibration absorbers 102 is larger than the number of the first vibration absorbers 101.

In this way, the number of the second vibration absorbers 102 may be larger than the number of the first vibration absorbers 101. As a result, the support 25 can be attached to the casing 20 more reliably, and the transmission of vibration can be further suppressed. The vibration and vibration noise of the toilet seat 14 can be further suppressed, and the comfort of the sanitary cleaning device 10 can be further improved.

FIG. 10 is a perspective view showing the connection between the multifunctional unit and the washing water supply unit and the connection between the multifunctional unit and the spray nozzle according to another embodiment.
As described above, the multifunctional unit 30 is attached to the base plate 24 via the support 25, the first vibration absorber 101, and the second vibration absorber 102.
Further, in the connection between the multifunctional unit 30 and the cleaning water supply unit 28 described above, the multifunctional unit 30 (electrolytic cell 52) is connected to the cleaning water supply unit 28 (heat exchanger) via the flexible tube T11. It is connected to 51). Further, the multifunctional unit 30 (flow control / flow path switching valve 55) is connected to the spray nozzle 38 via a flexible tube T26.

Here, in general, the flexible tubes T11 and T21 have a straight tubular shape before attachment. Then, when the tubes T11 and T21 are attached, the straight tubular tubes T11 and T21 are bent according to the arrangement form.
Further, as shown in FIG. 10, the multifunctional unit 30, the washing water supply unit 28, and the spray nozzle 38 are provided close to each other. Therefore, the lengths of the tubes T11 and T21 are shortened.
In this case, when the flexible tubes T11 and T21 are bent, the tubes T11 and T21 are subjected to an elastic force that tends to return to the original form. Then, when the lengths of the tubes T11 and T21 are short, the elastic force generated becomes large.

The generated elastic force acts on the multifunctional unit 30, the washing water supply unit 28, and the spray nozzle 38.
Since the washing water supply unit 28 and the spray nozzle 38 are attached to the base plate 24, there is little possibility that misalignment or the like will occur even if an elastic force acts.
However, the multifunctional unit 30 is attached to the base plate 24 via the support 25, the first vibration absorber 101, and the second vibration absorber 102. Therefore, when an elastic force acts on the multifunctional unit 30, the first vibration absorber 101 and the second vibration absorber 102 may be deformed and the multifunctional unit 30 may be tilted. When the multifunction unit 30 is tilted, the loads applied to each of the plurality of first vibration absorbers 101 and the plurality of second vibration absorbers 102 become uneven. If the load applied to each of the plurality of first vibration absorbers 101 and the plurality of second vibration absorbers 102 becomes uneven, the desired vibration isolation performance may not be obtained.

Therefore, in the present embodiment, the tubes 39 and 47 in the desired form are used instead of the flexible tubes T11 and T21.
As shown in FIG. 10, the multifunctional unit 30 (flow control / flow path switching valve 55) is connected to the spray nozzle 38 via the tube 39.
The multifunctional unit 30 (electrolytic cell 52) is connected to the washing water supply unit 28 (heat exchanger 51) via the tube 47.
The form of the tube 39 can be appropriately determined depending on the positional relationship between the predetermined multifunction unit 30 (flow control / flow path switching valve 55) and the spray nozzle 38.
The form of the tube 47 can be appropriately determined depending on the positional relationship between the multifunctional unit 30 (electrolytic cell 52) and the washing water supply unit 28 (heat exchanger 51), which are predetermined.
The materials of the tubes 39 and 47 are not particularly limited. However, considering the workability when mounting the tubes 39 and 47, the mounting position accuracy of the multi-function unit 30, the spray nozzle 38, and the washing water supply unit 28, the effect of absorbing the vibration generated in the multi-function unit 30, and the like. The materials of the tubes 39 and 47 are preferably flexible materials such as silicone resin. Since the tubes 39 and 47 are formed in a desired shape in advance, the amount of deformation generated at the time of attachment is small. Therefore, the elastic force generated even for the flexible tubes 39 and 47 is small.

By using the tubes 39 and 47 in the desired form, it is possible to significantly reduce the elastic force generated between the upstream functional portion and the downstream functional portion when the tubes 39 and 47 are attached. Therefore, the influence on the posture and arrangement in which the multifunctional unit 30 is held can be reduced, so that the load applied to each of the plurality of first vibration absorbers 101 and the plurality of second vibration absorbers 102 is not applied. It is possible to suppress the equalization. As a result, it becomes easy for the first vibration absorber 101 and the second vibration absorber 102 to exhibit desired vibration isolation performance.
