For example, by making the output of the second fan unit 100b larger than that of the first fan unit 100a, the direction of the air blown out from the outlet 102d is changed to the center side in the left-right direction, and the user's "buttocks" can be directed.

Further, as shown in FIG. 6, the duct portion 102b is inclined in a direction away from the center in the left-right direction toward the front. As a result, for example, even when an appropriate gap is set between the openings 20a and 20b so as to suppress contact between the nozzle damper 25 and the hot air damper 26 when both are opened at the same time, the fan unit 100a can be operated more efficiently. It can be arranged closer to the ejection nozzle 50 side. Wasteful space in the case cover 20 can be suppressed, and the storage space in the case cover 20 can be utilized more efficiently.

As shown in FIGS. 4 and 5, the air heating section 104 is provided inside the duct section 102b and heats the air passing through the duct section 102b. For the air heating unit 104, for example, an AC100V Nichrome wire heater is used.

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

The hot air unit 60 can blow hot air in which the air heated by the first fan 100a and the air heating section 104 is mixed with the air passing through the second fan 100b. In that case, when the second fan 100b is driven, at least the first fan 100a and the air heating unit 104 are driven first, and the heated warm air is blown out from the opening 20b. As a result, the warm air that has passed through the air heating section 104 is always included in the air that hits the user's buttocks, and discomfort caused by the cold wind can be suppressed.

The drive board 108 is housed in the board housing portion 102e. The drive board 108 is connected to the controller 62 and the air heater 104 , for example, and drives the air heater 104 according to instructions from the controller 62 . The control unit 62 drives the air heating unit 104 based on the temperature preset via the operation unit 66, for example, and feedback-controls the driving 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 blown out from the opening 20 b of the case cover 20 .

7(a) to 7(c) are a perspective view and a cross-sectional view showing the fan unit.
As shown in FIGS. 7A to 7C, the fan unit 100a and the fan unit 100b each have a fan motor 120 and a housing 122 that accommodates the fan motor 120. As shown in FIG. Note that FIG. 7(c) represents a cross section taken along line A1-A2 of FIG. 7(a).

The fan motor 120 has a motor portion 123 and blade portions 124 rotatably provided on the motor portion 123 about the rotation axis RA. The motor unit 123 is, for example, a DC 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) of the fan motor 120 in the direction perpendicular to the rotation axis RA.

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 . A length D1 of the housing 122 in a direction parallel to the rotation axis RA is shorter than a length D2 of the housing 122 in a direction perpendicular to the rotation axis RA. In other words, the length D1 of the fan unit 100 in the direction parallel to the rotation axis RA is shorter than the length D2 of the fan unit 100 in the direction perpendicular to the rotation axis RA.

The housing 122 has a motor support 125 , a main air intake 126 , an auxiliary air intake 127 and a jet 128 . The motor support portion 125 is provided facing the fan motor 120 on one side of the rotation axis RA and supports the motor portion 123 of the fan motor 120 .

Main intake port 126 is provided to face fan motor 120 on the other side of rotation axis RA, and exposes at least a portion of 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 vane portion 124 . That is, the main air intake port 126 exposes substantially the entire fan motor 120 .

Auxiliary intake port 127 is provided around motor support portion 125 on one side of rotation axis RA, and exposes a portion of fan motor 120 . For example, a plurality of auxiliary intake ports 127 are provided. Each auxiliary intake port 127 is provided side by side around the rotation axis RA around the motor support portion 125 . At this time, the number of auxiliary air inlets 127 is set to five or more, and the motor support portion 125 is connected to the surrounding portion via at least five connecting portions 129 extending radially. Thereby, for example, the supporting strength of the motor section 123 can be increased. For example, vibration of the warm air drying unit 60 caused by driving the motor section 123 can be suppressed.

The ejection port 128 is provided in a direction orthogonal to the rotation axis RA. The ejection port 128 exposes a portion of the blade portion 124 in the direction perpendicular to the rotation axis RA.

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

FIG. 8 is an exploded perspective view showing the duct unit.
As shown in FIG. 8 , the duct unit 102 has a first duct member 141 and a second duct member 142 separated in a cross section perpendicular to the rotation axis RA of the fan motor 120 . The duct unit 102 holds the fan unit 100a in the holding portion 102a by sandwiching the fan unit 100a between the first duct member 141 and the second duct member 142. As shown in FIG.

The first duct member 141 has openings 141a that expose the auxiliary air intakes 127 when the fan unit 100 is held. The second duct member 142 has an opening 142a that exposes the main air intake port 126 when the fan unit 100a is held.

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

The leaf spring portions 147 and 148 extend in a direction parallel to the rotation axis RA, press the fan unit 100a in a direction perpendicular to the rotation axis RA in a state in which the fan unit 100a is held, and rotate the rotation axis RA of the fan unit 100a. Regulates the position in the orthogonal direction.

In this manner, the duct unit 102 sandwiches the fan unit 100a between the first duct member 141 and the second duct member 142, and positions the fan unit 100a with the leaf spring portions 143-148. As a result, vibration of the fan unit 100 caused by driving the fan motor 120 can be suppressed. The number of leaf spring portions 143 to 148 is not limited to the above, and any number that can determine the position of the fan unit 100a may be used.

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

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

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

The hot air drying unit 60 is arranged on the opposite side of the electromagnetic valve 40, the washing water heating section 42, the flow switching valve 44, the flow path switching valve 46, the control section 62, and the power supply circuit 64, with the ejection nozzle 50 interposed therebetween. .

As shown in FIG. 9, the warm air drying unit 60 has a rotation axis RA that is substantially horizontal, an air outlet 102d that faces forward, and a main air inlet 126 that includes the washing water heating unit 42, the control unit 62, and a heat source such as the power supply circuit 64 is attached to the case plate 28 . The heat source may be any member that generates heat within the case cover 20 during operation of the sanitary washing device 10 . The heat source includes at least one of the cleaning water heating unit 42, the control unit 62, and the power supply circuit 64, for example. Thus, the warm air drying unit 60 is mounted with the main air intake 126 facing the heat source. That is, the fan unit 100 sucks air warmed by the heat source when the fan motor 120 is driven. As a result, the amount of heating required in the air heating unit 104 can be suppressed, and power consumption can be reduced.

The ejection nozzle 50 is provided substantially in the center of the case plate 28 in the left-right direction. The electromagnetic valve 40 , the cleaning water heating section 42 , the flow rate switching valve 44 , the flow path switching valve 46 , the control section 62 , and the power supply circuit 64 are provided on one of the left and right sides of the ejection nozzle 50 .

As shown in FIGS. 4, 5, and 10, the jet port 128 of the fan motor 120 is provided at a position extending tangentially to the rotational direction RD of the blade portion 124. As shown in FIG. The housing 122 holds the fan motor 120 with the ejection port 128 arranged upward. In other words, housing 122 holds fan motor 120 so that the air blown from the outer peripheral side of blade portion 124 is positioned above the air blown from the inner peripheral side of blade portion 124 .

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

When the hot air drying unit 60 is arranged vertically, it is necessary to retract the front end side of the duct portion 102b downward due to the positional relationship with the opening 20b of the case plate 20 as described above. Also, the wind blown out 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 positioned above the side with the high wind speed, the slow wind will contact the upper inclined surface inside the duct portion 102b, resulting in an increase in pressure loss. Moreover, if the warm air warmed by the air heating unit 104 stays in the duct part 102b, for example, the temperature of the duct part 102b may rise excessively. For example, the deterioration of the durability of the duct portion 102b is caused. Therefore, as described above, the fan motor 120 is held so that the wind blown from the outer peripheral side of the blade portion 124 is arranged above the wind blown from the inner peripheral side of the blade portion 124 . Accordingly, it is possible to prevent the air blown from the fan motor 120 from remaining in the duct portion 102b. For example, pressure loss can be suppressed and wasteful power consumption can be reduced.

FIG. 11 is a side view showing the tip of the hot air drying unit.
As shown in FIG. 11, a first damper 26a is rotatably provided above the air passage outlet at the tip of the hot air drying unit 60, and a second damper 26b is provided below the air passage outlet.
If the two winds are merged, the merged winds may spread vertically and deviate from the target location, resulting in a decrease in drying efficiency. By providing the vertically rotatable damper as described above, it is possible to prevent the diffusion of the wind, so that the target place can be dried efficiently.

In addition to the first damper 26a and the second damper 26b, a third damper on the left side of the air passage outlet and a fourth damper on the right side of the air passage outlet may be rotatably provided. By adopting the above configuration, diffusion can be suppressed not only in the vertical direction but also in the horizontal direction, so that the air can be sent to a more targeted place and the drying can be efficiently performed.

12(a) and 12(b) are side views showing the tip of the hot air drying unit.

As shown in FIGS. 12(a) and 12(b), the tip portion 102c is formed separately from the duct portion 102b and configured to be attachable to the front end of the duct portion 102b. The tip portion 102c has an engaging portion 160, for example. The tip portion 102c is attached to the front end of the duct portion 102b by engaging the engaging portion 160 with the engaged portion 162 provided on the duct portion 102b. The tip portion 102c is detachably attached to the front end of the duct portion 102b, for example.

In this manner, the tip portion 102c can be attached to the front end of the duct portion 102b. Accordingly, for example, by replacing only the tip portion 102c, the hot air drying unit 60 can be applied to a plurality of models having different shapes of the case cover 20. FIG. Parts can be shared among a plurality of models, and the manufacturing cost of the hot air drying unit 60 and the sanitary washing device 10 can be reduced.

It should be noted that the method of attaching the tip portion 102c is not limited to the above, and any method that allows attachment to the front end of the duct portion 102b may be used. For example, the tip portion 102c may be configured so that it cannot be easily removed from the duct portion 102b after being attached to the front end of the duct portion 102b. For example, the tip portion 102c may be fixed to the front end of the duct portion 102b by gluing or the like.

Further effects and modifications can be easily derived by those skilled in the art. Therefore, the broader aspects of the invention are not limited to the specific details and representative embodiments so shown and described. Accordingly, various changes may be made without departing from the spirit or scope of the general inventive concept defined by the appended claims and equivalents thereof.
