The flow rate switching valve 44 and the flow rate switching valve 46 may be provided as one unit.

An ejection nozzle 50 is provided downstream of the flow rate switching valve 44 and the flow rate switching valve 46. The ejection nozzle 50 receives the driving force from the nozzle motor 52 and can advance into the bowl portion 4a of the toilet bowl 4 or retract into the inside of the case cover 20. That is, the nozzle motor 52 can advance and retreat the ejection nozzle 50 based on a command from the control unit 62.

The case cover 20 has an opening 20a and a nozzle damper 25. The opening 20a is provided at a position facing the ejection nozzle 50. The ejection nozzle 50 moves in and out of the case cover 20 through the opening 20a. The ejection nozzle 50 ejects the washing water from the ejection port 56 in a state where the ejection nozzle 50 is advanced to the outside of the case cover 20.

The nozzle damper 25 is rotatably attached to the case cover 20 and opens and closes the opening 20a. The nozzle damper 25 closes the opening 20a by hanging under its own weight, for example, when the ejection nozzle 50 retracts. Then, for example, when the ejection nozzle 50 advances, the nozzle damper 25 is pushed by the ejection nozzle 50 and rotates to open the opening 20a. The nozzle damper 25 may be opened and closed under the control of the control unit 62 by using, for example, a drive mechanism.

The nozzle cleaning chamber 54 can sterilize or clean the outer peripheral surface (body) of the ejection nozzle 50 by injecting sterilizing water or water from a water discharge portion (not shown) provided inside the nozzle cleaning chamber 54. Alternatively, the nozzle cleaning chamber 54 can sterilize or clean the portion of the ejection port 56 of the ejection nozzle 50 in the housed state.

The warm air drying unit 60 dries the human body part of the user who has been wet by washing by blowing warm air toward the human body part (“buttocks” or the like) of the user who also sits on the toilet seat. The hot air drying unit 60 is connected to the control unit 62. The hot air drying unit 60 switches between blowing out hot air and stopping hot air based on a command from the control unit 62.

The case cover 20 has an opening 20b and a warm air damper 26. The opening 20b is provided at a position facing the warm air drying unit 60. The warm air drying unit 60 blows warm air to the outside of the case cover 20 through the opening 20b. The warm air damper 26 is rotatably attached to the case cover 20 and opens and closes the opening 20b. The warm air damper 26 closes the opening 20b by hanging under its own weight, for example, when the warm air is stopped. Then, for example, when the warm air is blown out, the warm air damper 26 is pushed by the wind pressure and rotates to open the opening 20b. Like the nozzle damper 25, the warm air damper 26 may be opened and closed under the control of the control unit 62.

The control unit 62 is supplied with electric power from the power supply PS via the power supply circuit 64, and based on a signal from the operation unit 66 or the like, the control unit 62 includes a solenoid valve 40, a washing water heating unit 42, a flow rate switching valve 44, and a flow path switching valve 46. , The operation of the nozzle motor 52, the warm air drying unit 60, and the like are controlled. For example, the control unit 62 controls the blowing of warm air by the hot air drying unit 60 and the stop of the blowing.

The power supply PS is, for example, an AC power supply. The supply power supply PS is, for example, an AC 100V (effective value) commercial power supply. The power supply circuit 64 converts, for example, 100V AC power supplied from the supply power supply PS into DC power such as 5V, 12V, and 24V. Then, the power supply circuit 64 supplies the converted 5V, 12V, and 24V DC powers and 100V AC power to each part of the sanitary cleaning device 10. As a result, each part of the sanitary cleaning device 10 operates according to the power supply from the power supply circuit 64.

FIG. 4 is a perspective view showing a warm air drying unit of the sanitary cleaning device according to the embodiment.
FIG. 5 is a side view showing a warm air drying unit of the sanitary cleaning device according to the embodiment.
As shown in FIGS. 4 and 5, the warm air drying unit 60 includes a fan unit 100, a duct unit 102, an air heating unit 104, a temperature sensor 106, and a drive board 108. In FIG. 5, the internal configuration of the warm air drying unit 60 is shown by omitting a part of the duct unit 102.

The fan unit 100 sucks air according to the drive and ejects the sucked air. The fan unit 100 is controlled by the control unit 62 and ejects air under the control of the control unit 62. The control unit 62 operates the fan unit 100, for example, based on the air volume preset by the operation unit 66.

The duct unit 102 includes a holding portion 102a for holding the fan unit 100, a duct portion 102b for guiding the air ejected from the fan unit 100 to the opening 20b of the case cover 20, and a tip portion 102c provided with an outlet 102d. It has a substrate accommodating portion 102e for accommodating the drive substrate 108. The tip portion 102c is provided at the tip of the duct portion 102b, and the outlet 102d is arranged immediately after the opening 20b of the case cover 20.

The air heating unit 104 is provided in the duct unit 102b and heats the air passing through the duct unit 102b. For the air heating unit 104, for example, an AC100V-based nichrome wire heater is used.

The temperature sensor 106 is provided in the duct portion 102b on the downstream side in the traveling direction of the air with respect to the air heating portion 104, and detects the temperature of the air heated by the air heating portion 104. The temperature sensor 106 is connected to, for example, the control unit 62, and inputs the detection result to the control unit 62. For the temperature sensor 106, for example, a thermistor is used.

The drive board 108 is housed in the board accommodating portion 102e. The drive board 108 is connected to, for example, the control unit 62 and the air heating unit 104, and drives the air heating unit 104 according to the instructions of the control unit 62. For example, the control unit 62 drives the air heating unit 104 based on a preset temperature via the operation unit 66, and feedback-controls the drive of the air heating unit 104 according to the detection result of the temperature sensor 106. .. As a result, warm air having a desired air volume and temperature set by the user is ejected from the opening 20b of the case cover 20.

The duct unit 102 is provided with a terminal block 110. The terminal block 110 is detachably attached to the outer surface of the duct unit 102, for example. The terminal block 110 holds connectors 111 to 113 that relay the electrical connection between the hot air drying unit 60 and the control unit 62. The terminal block 110 rigidly connects the connectors 111 to 113 to the duct unit 102 in a state of being attached to the duct unit 102, for example. The terminal block 110 holds the connectors 111 to 113 detachably by engaging the engaging claws with the grooves provided in the connectors 111 to 113, for example.

The connector 111 relays, for example, the electrical connection between the temperature sensor 106 and the control unit 62. The connector 112 relays, for example, the electrical connection between the drive board 108 and the control unit 62. The connector 113 relays, for example, the electrical connection between the fan unit 100 and the control unit 62.

For example, a DC voltage of 5 V is applied to the temperature sensor 106 via the connector 111. For example, a DC voltage of 5 V is applied to the drive board 108 via the connector 112. For example, a DC voltage of 24 V is applied to the fan unit 100 via the connector 113.

On the other hand, when an AC voltage of 100 V is applied to the air heating unit 104, the AC voltage is applied to the drive board 108 via a wiring or a connector (not shown), and is applied to the air heating unit 104 via the drive board 108. It is applied. In this way, the terminal block 110 holds, for example, only the DC voltage system connectors 111 to 113.

A connector used for an AC voltage of 100 V is large in size and heavy in weight. Therefore, the terminal block 110 holds only the relatively lightweight DC voltage type connectors 111 to 113. Thereby, each connector 111 to 113 can be appropriately held. For example, it is possible to prevent the held connector from rattling due to vibration caused by driving the fan unit 100.

6 (a) to 6 (c) are perspective views and cross-sectional views showing the fan unit.
As shown in FIGS. 6A to 6C, the fan unit 100 includes a fan motor 120 and a housing 122 that houses the fan motor 120. Note that FIG. 6C shows a cross section taken along line A1-A2 of FIG. 6A.

The fan motor 120 has a motor unit 123 and a blade unit 124 rotatably provided on the motor unit 123 about the rotation shaft RA. The motor unit 123 is, for example, a direct current brushless motor. The blade portion 124 is, for example, a sirocco fan. The outer shape of the fan motor 120 is, for example, a disk shape. The length (width) of the fan motor 120 in the direction parallel to the rotation axis RA is shorter than the length (diameter) in the direction orthogonal to the rotation axis RA of the fan motor 120.

The housing 122 has a box shape surrounding the fan motor 120. The outer shape of the housing 122 (fan unit 100) is set to be slightly larger than the outer shape of the fan motor 120. The length D1 in the direction parallel to the rotation axis RA of the housing 122 is shorter than the length D2 in the direction orthogonal to the rotation axis RA of the housing 122. In other words, the length D1 in the direction parallel to the rotation axis RA of the fan unit 100 is shorter than the length D2 in the direction orthogonal to the rotation axis RA of the fan unit 100.

The housing 122 has a motor support portion 125, a main intake port 126, an auxiliary intake port 127, and a spout 128. The motor support portion 125 is provided on one side of the rotating shaft RA so as to face the fan motor 120, and supports the motor portion 123 of the fan motor 120.

The main intake port 126 is provided on the other side of the rotating shaft RA so as to face the fan motor 120, and exposes at least a part of the fan motor 120. The main intake port 126 is a substantially circular through hole. The diameter of the main intake port 126 is formed to be approximately the same as the diameter of the blade portion 124. That is, the main intake port 126 exposes substantially the entire fan motor 120.

The auxiliary intake port 127 is provided around the motor support portion 125 on one side of the rotating shaft RA to expose a part of the fan motor 120. A plurality of auxiliary intake ports 127 are provided, for example. The auxiliary intake ports 127 are provided side by side around the rotation shaft RA around the motor support portion 125. At this time, the number of auxiliary intake ports 127 is set to 5 or more, and the motor support portion 125 is connected to the surrounding portion via at least 5 connecting portions 129 extending radially. Thereby, for example, the supporting strength of the motor unit 123 can be increased. For example, it is possible to suppress the vibration of the warm air drying unit 60 accompanying the driving of the motor unit 123.

The spout 128 is provided in a direction orthogonal to the rotation axis RA. The spout 128 exposes a part of the blade portion 124 in a direction orthogonal to the rotation axis RA.

As a result, in the fan unit 100, by driving the motor unit 123 and rotating the blade unit 124, air is sucked from the main intake port 126 and each auxiliary intake port 127, and the sucked air is ejected from the ejection port 128. Will be done.

FIG. 7 is an exploded perspective view showing the duct unit.
As shown in FIG. 7, the duct unit 102 has a first duct member 141 and a second duct member 142 separated in a cross section orthogonal to the rotation axis RA of the fan motor 120. The duct unit 102 holds the fan unit 100 in the holding portion 102a by sandwiching the fan unit 100 between the first duct member 141 and the second duct member 142.

The first duct member 141 has an opening 141a that exposes each auxiliary intake port 127 while holding the fan unit 100. The second duct member 142 has an opening 142a that exposes the main intake port 126 while holding the fan unit 100.

Further, the first duct member 141 has a plurality of leaf spring portions 143 to 148. The leaf spring portions 143 to 146 are provided around the opening 141a, and while holding the fan unit 100, press the fan unit 100 in a direction parallel to the rotation shaft RA and are parallel to the rotation shaft RA of the fan unit 100. Regulate the position of the direction. In other words, the leaf spring portions 143 to 146 press the fan unit 100 against the second duct member 142 to regulate the position of the fan unit 100.

The leaf spring portions 147 and 148 extend in a direction parallel to the rotation axis RA, and while holding the fan unit 100, press the fan unit 100 in a direction orthogonal to the rotation axis RA to and the rotation axis RA of the fan unit 100. Regulate the position in the orthogonal direction.

In this way, the duct unit 102 sandwiches the fan unit 100 between the first duct member 141 and the second duct member 142, and positions the fan unit 100 between the leaf spring portions 143 to 148. As a result, it is possible to suppress the vibration of the fan unit 100 that accompanies the driving of the fan motor 120. The number of leaf spring portions 143 to 148 is not limited to the above, and may be any number capable of determining the position of the fan unit 100.

The length D3 (see FIG. 4) in the direction parallel to the rotation axis RA of the duct unit 102 is slightly longer than the length D1 in the direction parallel to the rotation axis RA of the fan unit 100. More specifically, the length D3 is the length obtained by adding the wall thicknesses of the first duct member 141 and the second duct member 142 to the length D1.

Similarly, the length D4 (see FIG. 4) in the direction orthogonal to the rotation axis RA of the duct unit 102 is slightly longer than the length D2 in the direction orthogonal to the rotation axis RA of the fan unit 100.

Therefore, the length D3 in the direction parallel to the rotation axis RA of the duct unit 102 is shorter than the length D4 in the direction orthogonal to the rotation axis RA of the duct unit 102. In other words, the length D3 in the direction parallel to the rotation axis RA of the warm air drying unit 60 is shorter than the length D4 in the direction orthogonal to the rotation axis RA of the warm air drying unit 60.

The solenoid valve 40, the washing water heating unit 42, the flow rate switching valve 44, the flow path switching valve 46, the control unit 62, and the power supply circuit 64 are provided on one of the left and right sides with respect to the ejection nozzle 50. In this example, they are located on the right side of the ejection nozzle 50.

On the other hand, the warm air drying unit 60 is provided on the left and right sides of the ejection nozzle 50. The hot air drying unit 60 is arranged on the opposite side of the solenoid valve 40, the washing water heating unit 42, the flow rate switching valve 44, the flow rate switching valve 46, the control unit 62, and the power supply circuit 64 with the ejection nozzle 50 interposed therebetween. ..

Further, as shown in FIG. 8, in the warm air drying unit 60, the rotation axis RA is substantially horizontal, the outlet 102d faces forward, and the main intake port 126 is the washing water heating unit 42, the control unit 62, And, it is attached to the case plate 28 in a state of facing the heat source side such as the power supply circuit 64. The heat source may be any member that generates heat in the case cover 20 when the sanitary cleaning device 10 is operated. The heat source includes, for example, at least one of a washing water heating unit 42, a control unit 62, and a power supply circuit 64.

In this way, the warm air drying unit 60 is attached with the main intake port 126 facing the heat source side. That is, the fan unit 100 sucks the air warmed by the heat source when the fan motor 120 is driven. As a result, the amount of heating required for the air heating unit 104 can be suppressed, and power consumption can be reduced.

As described above, the length D3 in the direction parallel to the rotation axis RA of the warm air drying unit 60 is shorter than the length D4 in the direction orthogonal to the rotation axis RA of the warm air drying unit 60. Therefore, when the warm air drying unit 60 is attached as shown in FIG. 8, the length (width) of the warm air drying unit 60 in the left-right direction is shorter than the length (height) in the vertical direction. In other words, the warm air drying unit 60 is vertically arranged in the case cover 20. Thereby, for example, the warm air drying unit 60 can be efficiently arranged in the case cover 20. The storage space inside the case cover 20 can be efficiently used.

The sanitary cleaning device 10 further includes, for example, a first deodorizing unit 81 and a second deodorizing unit 82.

The second deodorizing unit 82 is arranged adjacent to the left side of the first deodorizing unit 81. The arrangement of the warm air drying unit 60, the first deodorizing unit 81, and the second deodorizing unit 82 is not limited to the above, and may be any arrangement.

FIG. 9 is a partial cross-sectional view showing an attached state of the warm air drying unit.
As shown in FIGS. 4, 5 and 9, the duct unit 102 of the warm air drying unit 60 further includes engaging portions 102f and 102g and abutting portions 102h. The engaging portion 102f is provided on the lower rear end side of the duct unit 102 and engages with the engaged portion 28a of the case plate 28. The engaging portion 102g is provided on the lower front end side of the duct unit 102 and engages with the engaged portion 28b of the case plate 28.

The contact portion 102h is provided between the engaging portion 102f and the engaging portion 102g at the lower part of the duct unit 102. The contact portion 102h comes into contact with the upper surface 28u of the case plate 28 in a state where the engaging portions 102f and 102g are engaged with the engaged portions 28a and 28b.

Further, in the contact portion 102h, the engaging portion 102g is engaged in the state where the engaging portion 102f is engaged with the engaged portion 28a and the contact portion 102h is in contact with the upper surface 28u of the case plate 28. The height dimension is adjusted so that it is located slightly above the portion 28b.

In attaching the warm air drying unit 60, the engaging portion 102f is engaged with the engaged portion 28a, and the contact portion 102h is brought into contact with the upper surface 28u of the case plate 28. In this state, the engaging portion 102g is engaged with the engaged portion 28b while slightly bending the front end portion of the duct unit 102 downward with the contact portion 102h as a fulcrum. As a result, the warm air drying unit 60 is attached to the case plate 28.

By mounting as described above, the warm air drying unit 60 is mounted on the case plate 28 in a state of being bowed upward. As a result, the warm air drying unit 60 can be attached to the case plate 28 in closer contact with the case plate 28. For example, even when the warm air drying unit 60 is arranged vertically, an appropriate mounting strength can be obtained. For example, the vibration of the warm air drying unit 60 when the fan motor 120 is driven can be suppressed, and the generation of abnormal noise can be suppressed.

As shown in FIGS. 4, 5, and 9, the ejection port 128 of the fan motor 120 is provided at a position extending in the tangential direction of the rotation direction RD of the blade portion 124. Then, the housing 122 holds the fan motor 120 with the ejection port 128 arranged above. In other words, the housing 122 holds the fan motor 120 so that the wind ejected from the outer peripheral side of the blade portion 124 is arranged above the wind ejected from the inner peripheral side of the blade portion 124.

The duct portion 102b of the duct unit 102 inclines downward toward the front and guides the wind so as to blow down from above. Further, the duct portion 102b withers the upper end side downward toward the front. The vertical length of the duct portion 102b becomes shorter toward the front.

When the warm air drying unit 60 is arranged vertically, it is necessary to wither the front end side of the duct portion 102b downward as described above because of the position of the case plate 20 with the opening 20b. Further, the wind ejected from the fan motor 120 tends to be faster on the outer peripheral side of the blade portion 124 than on the inner peripheral side of the blade portion 124.

At this time, if the side with the slow wind speed is located above the side with the high wind speed, the slow wind comes into contact with the inclined surface of the upper part inside the duct portion 102b, and the pressure loss becomes large. Further, if the warm air warmed by the air heating unit 104 stays in the duct portion 102b, for example, the temperature of the duct portion 102b may rise excessively. For example, the durability of the duct portion 102b is lowered.

Therefore, as described above, the fan motor 120 is held so that the wind ejected from the outer peripheral side of the blade portion 124 is arranged above the wind ejected from the inner peripheral side of the blade portion 124. As a result, it is possible to prevent the wind ejected from the fan motor 120 from staying in the duct portion 102b. For example, pressure loss can be suppressed and wasteful power consumption can be reduced.
