FIG. 8D is a schematic cross-sectional view showing a state of warm air blown out from the warm air outlet 12 of the drying device of the main body 200.
[0084]
As shown in FIG. 8A, the drying nozzle 1 before the drying switch 307 of the remote operation device 300 is pressed is stored in the casing 201 of the main body 200. Then, as shown in FIG. 8B, when the drying switch 307 of the remote operation device 300 is pressed, the control unit 5 gives a rotation instruction to the motor 6. The motor 6 causes the drying nozzle 1 to protrude from the inside of the casing 201 of the main body 200 in the direction of arrow Z in response to the rotation instruction.
[0085]
Subsequently, as shown in FIG. 8C, the warm air OP heated by the heater 11 is jetted from the warm air outlet 12. In this case, as shown in FIG. 8D, the surroundings of the drying nozzle 1 are filled with the warm air OP ejected from the warm air outlet 12.
[0086]
As a result, the drying nozzle 1 can suck the warm air OP from the air suction port 120 and mix it with the compressed air supplied from the pressure accumulating tank 3 to blow it out. Further, by moving the drying nozzle 1 in the front-rear direction, compressed air can be ejected to the entire surface to be dried. Further, since the drying nozzle 1 is provided with the plurality of ejection ports 110, when the drying nozzle 1 moves in the direction of the arrow Z, the compressed air can be ejected to a wide area of the surface to be dried of the human body. As a result, the surface to be dried can be efficiently dried with air at an appropriate temperature.
[0087]

[0088]
As shown in FIG. 9A, the warm air outlets 12α are provided on both inner sides of the toilet seat 400. Therefore, the hot air outlet 12α is located at a position closest to the air suction port 120 of the drying nozzle 1 when the drying nozzle 1 projects most.
[0089]
That is, the distance L2 from the warm air outlet 12α to the drying nozzle 1 is shorter than the distance L1 from the warm air outlet 12 to the drying nozzle 1.
[0090]
Therefore, the warm air blown out from the warm air outlet 12α can surely reach the drying nozzle 1. As a result, as shown in FIG. 9B, the drying nozzle 1 can efficiently suck a large amount of hot air OP from the hot air outlet 12α, and the drying nozzle 1 is further accumulated in the pressure accumulating tank 3. A large amount of warm air can be blown to the surface to be dried by mixing with the compressed air.
[0091]

A large amount of warm air OP can be efficiently sucked from the compressed air 12 and the compressed air stored in the pressure accumulation tank 3 can be ejected. Therefore, the local part of the human body can be efficiently dried in a short time. Further, since the time spent for drying can be reduced, it is possible to prevent inflammation caused by blowing high-temperature hot air to a local area.

[0102]
On the other hand, the air compressed by the air pump 2 is stored in the pressure accumulation tank 3. Then, the compressed air accumulated in the pressure accumulation tank 3 by the opening and closing operation of the solenoid valve 4 is intermittently ejected from the drying nozzle 1a.

As shown in FIG. 12B, the compressed air supply unit 112a communicates with the compressed air supply unit 111a in an L-shape. The compressed air supply section 111a and the compressed air ejection section 112a have compressed air passages therein. An ejection port 110a is provided at the tip of the compressed air ejection section 112a. The distal end of the compressed air ejection portion 112a is formed in a cylindrical shape, and a cylindrical peripheral wall portion 121a is formed so as to surround the distal end of the compressed air ejection portion 112a with a certain gap. Hereinafter, one opening of the peripheral wall portion 121a on the distal end side of the compressed air ejection portion 112a is referred to as an air outlet 130a, and the other opening of the peripheral wall portion 121a is referred to as an air inlet 130b.
[0106]
Next, the operation of the drying nozzle 1a will be described. As shown in FIG. 7B, compressed air is ejected from the ejection port 110a to the surface M to be dried of the human body.
[0107]
In this case, the compressed air ejected from the ejection port 110a is ejected at high speed to the outside through the space surrounded by the peripheral wall portion 121a, so that the air pressure in the peripheral wall portion 121a decreases, and Negative pressure. Therefore, air is sucked into the inside of the peripheral wall portion 121a from outside through the air suction port 130b of the peripheral wall portion 121a, and is mixed with the compressed air ejected from the ejection port 110a. Thereby, a large amount of air is jetted from the air jet port 130a to the surface to be dried.
[0108]
FIG. 13 is a schematic diagram showing the operation of the drying nozzle 1a of FIG.
FIG. 13A shows a schematic cross section of the inside of the casing 201 of the main body 200 before the drying switch 307 of the remote control device 300 is pressed down, and FIG. 13C shows a schematic cross section of the inside of the casing 201 of the main body 200 after the pressing operation, FIG. 13C shows an example of the appearance of FIG. 13B, and FIG. 13D and FIG. FIG. 13F shows a state after the drying nozzle 1a is rotated by 180 degrees by the operation of the motor 13. FIG.
[0109]
First, as shown in FIG. 13A, before the drying switch 307 of the remote control device 300 is pressed down, the drying nozzle 1a is housed in the casing 201 of the main body 200. Then, when the drying switch 307 of the remote operation device 300 is pressed down, the control unit 5 gives a rotation instruction to the motor 6. In response to the rotation instruction, the motor 6 causes the drying nozzle 1a to protrude in the direction of arrow Z from inside the casing 201 of the main body 200, as shown in FIGS. 13B and 13C.
[0110]
After the drying nozzle 1a protrudes to a predetermined position, the control unit 5 sends air downward (in a direction opposite to the surface to be cleaned) from the ejection port 110a as shown in FIGS. 13B and 13C. Let it squirt. Subsequently, after a predetermined time has elapsed, the control unit 5 gives a rotation instruction to the motor 13. In response to the rotation instruction, the motor 13 rotates the drying nozzle 1a by 180 degrees in the direction of the arrow Y as shown in FIGS. 13D and 13E. Then, as shown in FIG. 13 (f), the control unit 5 causes air to be ejected upward (in the direction of the surface M to be cleaned) from the ejection port 110a.
[0111]
FIG. 14 is a diagram illustrating the effect when the drying nozzle 1a of FIG. 12 is rotated. FIG. 14A shows a state of the drying nozzle 1a before being rotated, and FIG. 14B shows a state of the drying nozzle 1a after being rotated by 180 degrees.
[0112]
First, as shown in FIG. 14A, the drying nozzle 1a rotates so that the air suction port 130b faces the surface M to be cleaned. Accordingly, the drying nozzle 1a ejects compressed air from the ejection port 110a in a direction opposite to the surface M to be dried.
[0113]
In this case, the compressed air ejected from the ejection port 110a is ejected at high speed to the outside through the space surrounded by the peripheral wall portion 121a, so that the air pressure in the peripheral wall portion 121a decreases, and Negative pressure. Therefore, air is sucked into the interior of the peripheral wall portion 121a from the outside through an air suction port 130b provided in the peripheral wall portion 121a, and is mixed with the compressed air ejected from the ejection port 110a. As a result, water droplets attached to the surface M to be dried are sucked in from the air suction port 130b of the peripheral wall portion 121a, and are discharged from the air ejection port 130a.
[0114]
Next, as shown in FIG. 14B, the drying nozzle 1a rotates so that the air suction port 130a faces the surface M to be dried. Thus, compressed air is ejected upward from the ejection port 110a of the drying nozzle 1a toward the surface M to be dried.
[0115]
In this case, the compressed air ejected from the ejection port 110a is ejected at high speed to the outside through the space surrounded by the peripheral wall portion 121a, so that the air pressure in the peripheral wall portion 121a decreases, and Negative pressure. Therefore, air is sucked into the inside of the peripheral wall portion 121a from the outside through an air suction port 130b provided in the peripheral wall portion 121a, and is mixed with the compressed air ejected from the ejection port 110. As a result, a large amount of air is ejected from the air ejection port 130a to the surface M to be dried.
[0116]
Therefore, the local part of the human body can be efficiently dried in a short time. Further, since the time spent for drying can be reduced, it is possible to prevent inflammation caused by blowing high-temperature warm air to a local part of a human body.
[0117]
FIG. 15 is a schematic sectional view showing another example of the drying nozzle 1 shown in FIG.
As shown in FIG. 15, the drying nozzle 1b includes a compressed air supply unit 111b and a compressed air ejection unit 112b. The compressed air ejection part 112b communicates with the compressed air supply part 111b in an L-shape. The compressed air supply unit 111b and the compressed air ejection unit 112b have compressed air passages therein. An ejection port 110a is provided at the tip of the compressed air ejection section 112b. The distal end of the compressed air ejection portion 112b is formed in a cylindrical shape, and a cylindrical peripheral wall portion 121b is formed so as to surround the distal end of the compressed air ejection portion 112b with a certain gap. The opening of the peripheral wall portion 121b on the side of the ejection port 110a is closed by the flat portion 121c. Further, a gas flow path 122b communicating with the air suction port 130b of the peripheral wall portion 121b is formed in the peripheral wall portion 121b. A sponge 160 for absorbing moisture is provided on the flat portion 121c in the peripheral wall portion 121b. Further, an air ejection port 130a is formed on the air suction port 130b side of the gas flow path 122b.
[0118]
Next, the operation of the drying nozzle 1b will be described. Compressed air supplied from the pressure accumulating tank 3 via the electromagnetic valve 4 is jetted from the jet port 110a. The spout 110a faces in a direction opposite to the surface M to be dried.
[0119]
In this case, the compressed air ejected from the ejection port 110a is ejected at a high speed to the outside through the space surrounded by the peripheral wall portion 121b. Negative pressure. Therefore, air is sucked into the inside of the peripheral wall portion 121b from outside through an air suction port 130b provided in the peripheral wall portion 121b, and mixed with the compressed air ejected from the ejection port 110a. Thus, water droplets attached to the surface M to be dried can be sucked from the air suction port 130b of the peripheral wall portion 121b. Then, the moisture of the air sucked through the air suction port 130b can be removed by the sponge 160. Further, the dried air from which moisture has been removed by the sponge 160 is blown out to the surface M to be dried through the gas passage 122b.
[0120]
Accordingly, since the water droplets on the surface M to be dried can be removed and the dry compressed air can be jetted onto the surface M to be dried, the surface M to be cleaned can be dried in a shorter time.
[0121]
Therefore, the local part of the human body can be efficiently dried in a shorter time. Further, since the time spent for drying can be reduced, it is possible to prevent inflammation caused by blowing high-temperature warm air to a local part of a human body.
[0122]
FIG. 16 is a schematic sectional view showing another example of the drying nozzle 1 shown in FIG.
The drying nozzle 1c shown in FIG. 16 differs from the drying nozzle 1b shown in FIG. 15 in the following points.
[0123]
In the drying nozzle 1c of FIG. 16, a heater 170 is provided in a part of the gas flow path 122b. Therefore, when the compressed air ejected from the ejection port 110a flows through the gas passage 122b, the compressed air is heated by the action of the heater 170, and the heated air is transmitted from the air ejection port 130a of the peripheral wall portion 112b to the surface M to be dried. Is gushing.
[0124]
Thereby, the drying nozzle 1c in FIG. 16 can remove the water droplets on the surface M to be dried, and can also blow out the compressed air heated to the surface M to be dried. It can be performed.
[0125]
Therefore, the local part of the human body can be efficiently dried in a shorter time. Further, since the time spent for drying can be reduced, it is possible to prevent inflammation caused by blowing high-temperature warm air to a local part of a human body.
