Drying device and sanitary washing device provided with the same

Technical field

The present invention relates to a drying device that dries a wet surface by blowing air and a sanitary washing device including the drying device.

Background art

[0002] Various functions have been devised in a sanitary washing apparatus for washing a local part of a human body in order to realize washing according to user's preference. The user performed local cleaning using a sanitary cleaning device using various functions, and removed water droplets adhering to the local area using paper such as toilet paper. However, in recent years, a drying apparatus has been proposed as an alternative to paper such as toilet paper (see, for example, Patent Document 1). FIG. 21 is a schematic plan view showing an example of a sanitary washing apparatus equipped with a conventional drying apparatus. FIG. 22 is a schematic sectional side view of this conventional sanitary washing apparatus.

[0003] As shown in FIGS. 21 and 22, the sanitary washing device includes a toilet seat 2, a toilet lid 3, and a main body case 4 and 9 of the sanitary washing device including a water washing tank (low tank). It is configured.

[0004] The main body case 4 includes a hot air outlet 7 for blowing out hot air from the hot air blowing device 5, a washing water injection nozzle 8 for injecting hot water to the human body part, and hot water to the washing water injection nozzle 8. The pump 11 for supplying washing water and the hot water tank 12, the high-pressure air reservoir 14 for storing the air compressed by the air compressor 13, and the solenoid valve 15 for opening and closing the outlet of the high-pressure air reservoir 14 are incorporated.

[0005] The toilet seat 2 has a cavity 16 provided therein and an air ejection nozzle 18 having a plurality of holes for ejecting air in the cavity 16, and the electromagnetic valve 15 and the cavity 16 are connected by a high-pressure hose 17. Connected

[0006] When the human body 10 is seated on the toilet seat 2 and performs a washing operation after the stool, the washing water supply pump 11 is operated, and hot water is jetted from the washing water injection nozzle 8 to the surface to be cleaned through the hot water tank 12. This cleans the surface to be cleaned. The air compressor 13 is operated by the drying operation after washing, and the high pressure High-pressure air is jetted to the surface to be cleaned through the air reservoir 14, solenoid valve 15, high-pressure hose 17, cavity 16 and air jet nozzle 18, and water droplets adhering to the surface to be cleaned are blown off and scattered or diffused. Next, the hot air blowing device 5 is operated, hot air is blown out from the hot air outlet 7 through the air passage 6 and the surface to be cleaned is dried.

[0007] In the above-described conventional configuration, the compressed air in the high-pressure air reservoir 14 is released from the air ejection nozzle 18 composed of a plurality of holes to blow off water droplets on the surface to be cleaned in a short time. 14 and the air compressor 13 were stored in the main body case 4.

Meanwhile, in order to eject a large amount of air at a time as in the conventional example, it is necessary to enlarge the air compressor 13 or the high-pressure air reservoir 14. Therefore, if the capacity of the air compressor 13 is reduced and the high-pressure air reservoir 14 is increased, the main body case 4 is enlarged to accommodate the high-pressure air reservoir 14. In addition, increasing the capacity of the air compressor 13 not only increases the vibration noise, but also increases the cost. Furthermore, if the high-pressure air reservoir is placed away from the air compressor and installed outside the main unit case, it will stand out and the appearance of the toilet will deteriorate.

[0009] As a method for solving these problems, the apparatus can be reduced in size by reducing the amount of air ejected at a time by using a single air ejection nozzle hole. However, this method has a problem that the area of air to be blown is reduced, so that water droplets on the surface to be cleaned, which gets wet over a wide range, cannot be sufficiently dropped, and there is a problem in practical use.

[0010] In addition, the water droplets that have not been peeled off from the surface to be cleaned by the air jet from a certain direction move to the staying portion of the air jet and remain attached to the surface to be cleaned. In addition, there were problems such as water droplets diffusing to the surroundings due to the air jet and expanding the wet area.

[0011] In addition, an air nozzle device has been proposed for the purpose of moving a predetermined trajectory using a three-dimensional deflection means that realizes a compact, low-vibration and noise-free nozzle device (Patent Literature). 2). In Patent Document 2, the air nozzle is three-dimensionally deflected in two dimensions in the front-rear direction and in the left-right direction two-dimensionally with respect to the air ejection direction in conjunction with the air ejection. Or the air nozzle discharge port is sequentially deflected three-dimensionally counterclockwise or clockwise, and the direction of air ejection is deflected three-dimensionally toward the human body, thereby moving the ejected air along a predetermined trajectory. With 3D deflection means It is supposed to. In addition, since the discharge area of the air nozzle device can be greatly reduced relative to the area that receives the wind of the human body, the ejection speed can be significantly increased with a predetermined air volume, and it can adhere to the local area in a short time. The water drops can be removed.

[0012] However, although it is not clear in the above description, it is considered that the direction of air ejection is three-dimensionally deflected, and on the basis of this description, the direction of air nozzle ejection When performing the actual drying operation with the deflection of the above, paying attention to the relationship between the angle of the blown air and the surface to be dried, the water droplets in the peripheral part of the washed water droplets are further blown away and diffused to the periphery However, there is a problem that the surface to be dried increases due to the increase in the area of the wet part, and conversely it takes time to dry.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described.

Prior to the description, the concept of the present invention will be described.

[0020] First, the drying apparatus of the present invention injects pressurized air so as to dry the surface to be dried with a jet of pressurized air having a narrower contact range with the surface to be dried than the surface to be dried. And a moving means for moving the air jet part while jetting the jet so that the jet jetted from the air jet part sequentially sweeps substantially the entire surface to be dried. A first moving means for moving the air jetting portion in a state where the jetting direction of the jet flow is maintained so as to form a predetermined angle with respect to the moving direction of the air jetting portion; Second moving means for moving the air ejection part in a direction different from the direction.

[0021] According to this configuration, the surface to be dried is moved while sequentially moving the pressurized air along the surface to be dried while maintaining the jet direction of the jet so as to form a predetermined angle with respect to the moving direction of the air ejection portion. Can spray on the whole.

[0022] Water droplets adhering to the surface to be dried are more easily blown off by applying a jet with a higher wind speed. However, if the distance between the water droplet and the air ejection part is increased, the wind speed of the jet that hits the water droplet becomes extremely high. It drops and can no longer blow off water droplets. Therefore, it is better to keep the distance between the water droplet and the air ejection part as close as possible. Therefore, as in the present invention, by moving the air ejection part while maintaining the jet direction of the jet, it is possible to apply the jet while maintaining the surface to be dried and the air ejection part at a short distance, so that the surface adheres to the surface to be dried. It is possible to efficiently blow off water droplets.

[0023] Further, by moving the jet so as to sweep on the surface to be dried, water droplets attached to the surface to be dried can be blown away while moving in any direction, for example, the surface to be dried. Water drops can be collected at the center and efficiently blown away.

In particular, in the present invention, since the pressurized air with the jet contact area narrowed from the surface to be dried is moved sequentially over substantially the entire surface to be dried, a wide range of water droplets can be moved even with the air jet stream narrowed. The drying apparatus can be downsized.

[0024] Further, the present invention includes the above-described drying device in which the first moving unit moves in the advancing / retreating direction of the air ejection portion.

With this configuration, the advancing / retreating direction of the air ejection portion is a direction along the center line of the surface to be dried, that is, the front and rear direction of the collar portion. Therefore, the jet from the air jetting part is sprayed over the entire surface to be dried while moving in a state of maintaining a predetermined angle on the center line of the buttock. Since it is possible to apply a jet while maintaining the surface to be dried and the air jetting part at a short distance, it is possible to effectively disperse water droplets adhering to the surface to be dried.

[0025] Further, the present invention includes the above-described drying device, wherein the second moving unit deflects a jet direction of the jet.

With this configuration, the movement of the air ejection portion in the second moving means is a small operation that only deflects the ejection angle of the air ejection portion periodically, and the jet can move to the entire surface to be dried. The device can be miniaturized.

[0026] Further, the present invention includes the above drying device, wherein the second moving means moves in a direction different from the first moving means while maintaining the jet direction of the jet.

According to this configuration, while both the first moving means and the second moving means are maintained in the jet direction of the jet of the air jet section, the pressurized air is sequentially moved along the surface to be dried. Since the spray is applied to the entire surface, the surface to be dried and the air blowing part are close to each other over the entire surface to be dried. The jet can be applied while being kept apart. Therefore, the water droplets adhering to the surface to be dried can be efficiently scattered or the water droplets can be moved arbitrarily.

[0027] Further, in the drying apparatus according to the present invention, the second moving means includes a device that rotates the air jetting portion to deflect the jet flow.

With this configuration, the movement of the air ejection portion in the second moving means is a small operation that only rotates the air ejection portion periodically, and the jet can move over the entire surface to be dried.

The two moving means have a simple configuration, and the size of the drying apparatus can be reduced.

[0028] Further, the present invention includes the above-described drying device, wherein the second moving means swings a jet direction of a jet jetted from the air jet section.

With this configuration, the movement of the air ejecting portion in the second moving means is performed only by periodically oscillating the jet direction of the jet flow from the air ejecting portion, for example, by using self-excited deflection by a fluid element. Since the jet can move to the entire surface to be dried, the second moving means has a simple configuration, and the size of the drying apparatus can be reduced.

[0029] Further, the present invention includes the above-described drying device, wherein the second moving unit moves the air ejection part in a direction substantially orthogonal to a moving direction by the first moving unit.

According to this configuration, the combination of the movement of the air ejecting portion of the first moving means and the second moving means becomes a two-dimensional two-dimensional movement, and the movement control in which the position coordinates are easily understood is simplified. For this reason, the combined movement of the air ejection parts becomes smooth, so that it is easy to remove water droplets adhering to the surface to be dried and to move water droplets in any direction.

[0030] Further, in the drying apparatus according to the present invention, the second moving unit includes a unit that moves the air ejection portion in an arc shape.

With this configuration, the second moving means periodically performs, for example, a fan-shaped arc reciprocating operation with one point as a fulcrum. With this operation, both the first moving means and the second moving means are sprayed on the entire surface to be dried while sequentially moving the surface to be dried while maintaining the jet direction of the jet of the air ejection section. Operation can be achieved with a relatively simple configuration. With this configuration, it is possible to efficiently disperse or arbitrarily move water droplets adhering to the surface to be dried. [0031] Further, in the drying device according to the present invention, the air ejection part is a rod-like body provided with an air ejection hole in the vicinity of a tip, and a moving direction of the first moving means is a longitudinal direction of the rod-like body. Including those that are directions along the direction.

With this configuration, the projection area in the movement of the rod-shaped body can be minimized by making the longitudinal direction of the rod-shaped body coincide with the moving direction of the first moving means. Therefore, when the main body force of the drying apparatus is moved forward and backward with respect to the surface to be dried, it can be performed with a minimum movement trajectory. In other words, it is possible to smoothly carry out the loading / unloading force of the air blowing portion.

[0032] Further, in the drying apparatus according to the present invention, the moving unit blows off the water droplets adhering to the surface to be dried while collecting the water droplets in the center of the surface to be dried by a jet ejected from the air ejection unit. What sweeps the jet from the said air ejection part is included.

This is because when a jet of pressurized air is applied to water droplets adhering to the surface to be dried, the water droplets are likely to blow off if they hit the direct direction, but if the positions of the water droplets and the jets deviate, the water droplets follow the air flow. Just move, it will blow away, there are many things. The jet of pressurized air sprayed on the surface to be dried has the property of spreading over the entire surface to be dried. Therefore, by changing the position of the air jet against the water droplets that spread and adhere to the surface to be dried, the direction of air flow along the surface to be dried is changed so that the water droplets gather at the center of the surface to be dried. Is.

As a result, small water droplets that are dispersed cannot be blown unless a strong air jet is applied over a wide area, but large water droplets that have gathered can be easily blown even with few air jets. Moreover, if water droplets collect at the center of the surface to be dried, the force S can be applied to concentrate the air jet in a narrow area, so that the water droplets can be efficiently blown away.

[0033] Further, in the drying apparatus according to the present invention, the moving unit periodically moves the air jetting part to reciprocate periodically in one fixed direction, and gradually moves the periodic movement to a predetermined direction. Including movement, sweeping the contact area of the jet over almost the entire surface to be dried.

This is because water droplets adhering to the surface to be dried are blown in the same linear or belt shape as the periodic movement trajectory by one periodic movement, and are blown by repeating the periodic movement while moving novelly. The extended range is gradually expanded, and finally the adhered water on the entire surface to be dried is blown away. With this configuration, for example, by gradually reducing the moving range and the moving angle range and bringing the contact range of the air jet closer to the center of the surface to be dried, without stopping the air jet, Water droplets spread on the surface to be dried can be blown away while collecting in the center. Therefore, the operation is not wasted and the drying time can be shortened.

[0034] Further, in the drying apparatus according to the present invention, the moving unit is configured to move approximately from the outer periphery of the surface to be dried to the drying surface while periodically moving on a substantially tangential line around the center of the surface to be dried. It includes one that gradually moves the air ejection portion toward the center.

With this configuration, the air jet gradually moves toward the center while periodically moving in the tangential direction of the outer periphery of the water droplets adhering to the surface to be dried, so that the water droplets move toward the center of the surface to be dried and outward. Since it does not spread and the wetted area does not spread, it is possible to sweep while collecting water droplets on the surface to be dried more efficiently.

[0035] Further, the present invention includes the above drying apparatus, wherein the first moving means is a progressive movement, and the second moving means is periodically moved.

With this configuration, for example, if the progressive movement direction is the front-rear direction, water droplets adhering to the surface to be dried can be easily collected from the front side or the rear side to the center part, so water droplets on the surface to be dried can be removed more efficiently. can do.

[0036] Further, the present invention includes the above drying apparatus, wherein the first moving means is a periodic movement, and the second moving means is a progressive movement.

With this configuration, for example, when the progressive movement direction is the left-right direction, water droplets adhering to the surface to be dried can be easily collected from the left side or the right side to the central portion, so that water droplets on the surface to be dried are more efficiently removed. be able to.

[0037] Further, according to the present invention, in the above drying apparatus, the direction of the periodic movement of the moving means is the left-right direction of the surface to be dried, and gradually moves from a predetermined position forward from the center of the surface to be dried toward a substantially center. A first step, and a second step that gradually moves from a predetermined position behind the center of the surface to be dried toward a substantially center, and that executes the first step and the second step. Including.

With this configuration, for example, the moving range and the moving angle range are gradually reduced to By bringing the contact area of the flow closer to the center of the surface to be dried, water droplets spreading on the surface to be dried can be continuously blown away without stopping the air jet. Therefore, the operation is not wasted and the drying time can be shortened.

[0038] Further, according to the present invention, in the drying apparatus, the direction of the periodic movement of the moving means is the front-rear direction of the surface to be dried, and gradually advances from a predetermined position on either side of the surface to be dried toward a substantially center. A first step that moves, and a second step that gradually moves from a predetermined position on the left and right sides of the surface to be dried toward a substantially center, the first step and the second step. Including those that perform

With this configuration, water droplets adhering to the front from the center of the surface to be dried move in the central direction by the first step, and water droplets adhering to the rear from the center of the surface to be dried move in the central direction by the second step. As a result, the entire water droplets adhering to the surface to be dried can be collected in the center from the front and rear forces.

[0039] Further, according to the present invention, in the drying apparatus, the direction of the periodic movement of the moving unit is the left-right direction of the surface to be dried, and the first moving gradually from a predetermined position in front of the center of the surface to be dried toward a substantially center. And a second step that gradually moves from a predetermined position rearward from the center of the surface to be dried toward a substantially center, and a direction of periodic movement of the moving means is a front-rear direction, and a right and left from the center of the surface to be dried. A third step of gradually moving from one of the predetermined positions toward the approximate center and a fourth step of progressively moving from the center of the surface to be dried from the other predetermined position on the left and right toward the approximately center. And executing the first step to the fourth step.

With this configuration, water droplets adhering forward from the center of the surface to be dried move in the center direction by the first step, and water droplets adhering behind the center of the surface to be dried move in the center direction by the second step. Water droplets adhering to either the left or right side of the center of the surface to be dried move in the center direction by the third step, and water droplets adhering to the other side of the surface to be dried are driven by the fourth step. Since it moves in the center direction, the entire water droplets adhering to the surface to be dried can be collected from the front, back, left, and right directions in the center.

[0040] Further, the present invention includes the above-described drying device, wherein the moving means moves the contact range of the jet to the center while rotating around the periphery of the surface to be dried. With this configuration, when a jet of pressurized air is applied to water droplets attached to the surface to be dried, the water droplets are likely to blow off if the jet directly or near the water droplets. Therefore, water droplets that spread and adhere to the surface to be dried are moved to the center while circulating the position where the air jet strikes, so that the water droplets gather at the center of the surface to be dried.

As a result, it is possible to concentrate and spray the water droplets collected at the center of the surface to be dried, so that the water droplets can be efficiently blown off and the drying apparatus can be downsized.

[0041] Further, in the drying apparatus according to the present invention, the moving means moves to a central portion of the surface to be dried while circling on a polygon formed by a substantially tangent line around the center of the surface to be dried. Including what

With this configuration, the moving means moves the jet contact area to the center of the surface to be dried while circling on a substantially polygon formed by a substantially tangent line around the center of the surface to be dried. As the abutment area of the jet moves from the outer periphery of the surface to be dried over the polygon, it gradually approaches the center while the polygonal shape becomes smaller, so water droplets move toward the center of the surface to be dried. The wet area is not spread by being diffused to the outside. Moreover, if water droplets collect at the center of the surface to be dried, the air jet can be concentrated and applied to a narrow area, so that the water droplets can be efficiently blown away.

[0042] Further, the present invention includes the above-described drying apparatus, wherein the moving means moves to the center of the surface to be dried while circling substantially on the circumference around the center of the surface to be dried.

With this configuration, this causes the air jet to gradually move toward the center while periodically moving in the tangential direction of the outer periphery of the water droplets adhering to the surface to be dried, so that the water droplets move toward the center of the surface to be dried. The wet area is not spread by being diffused to the outside.

[0043] The present invention further includes a control unit for controlling the moving unit in the drying apparatus, wherein the control unit is configured to center the moving unit from one end of the surface to be dried while periodically moving the moving unit at the end of the drying process. Including those that move progressively through to the other end.

With this configuration, water droplets remaining in the prior drying step can be reliably removed. Further, after collecting water droplets at the center of the surface to be dried, the water droplets can be easily removed by gradually moving to the other end through the center of one end of the force to be dried.

[0044] Further, the present invention provides a heating means for heating air and the heating hand in the drying apparatus. The one provided with a hot air outlet from which hot air heated by a stage is discharged is included. With this configuration, in addition to injecting pressurized air onto the surface to be dried by the air jetting unit and blowing off water droplets, the surface to be dried is made more by blowing warm air heated by the heating means toward the surface to be dried. It can be dried efficiently in a short time. In addition, moisture on the surface to be dried can be removed by warm air, improving comfort after drying. Furthermore, the feeling of cold wind due to a jet of pressurized air can be prevented.

[0045] Further, the present invention provides the above-described drying device and a sanitary washing device including the same, including a toilet seat that can be seated, and washing water jetting means that jets washing water toward the surface to be washed. Including.

By providing the cleaning water jetting means and the drying device in this way, the positional relationship between the surface to be cleaned and the surface to be dried can be set optimally, so that efficient drying is possible. It is also possible to automate operations from cleaning to drying, which improves usability and convenience.

[0046] The washing water jetting means and the air jetting part may be constituted by one nozzle, or may be constituted by two independent nozzles which can be independently advanced and retracted.

[0047] In addition, the drying device is configured to dry with a jet of pressurized air having a narrower contact range than the surface to be dried, and includes an air ejection unit that ejects pressurized air, and a contact range of the jet from the air ejection unit Moving means for sequentially moving substantially the entire surface to be dried, and the moving means blows off water droplets adhering to the surface to be dried while collecting them at the center of the surface to be dried by the jet of the air jetting part. You may make it move to.

[0048] This is because, when a jet of pressurized air is applied to water droplets adhering to the surface to be dried, the water droplets are likely to blow off if they hit the direct, but if the positions of the water droplets and the jets deviate, the air flows. Just move the water droplets along, and it will blow away. The jet of pressurized air sprayed on the surface to be dried has the property of spreading over the entire surface to be dried. Therefore, by changing the position of the air jet against the water droplets that spread and adhere to the surface to be dried, the direction of air flow along the surface to be dried is changed so that the water droplets gather at the center of the surface to be dried. Is.

[0049] With this, small water droplets that are dispersed must be blown away unless a strong air jet is applied over a wide area, but large water droplets that have gathered can be easily blown even with few air jets. . Moreover, if water droplets collect at the center of the surface to be dried, the force S can be applied to concentrate the air jet in a narrow area, so that the water droplets can be efficiently blown away. In particular, in the present invention, since the pressurized air with the jet contact area narrowed more narrowly than the surface to be dried is moved sequentially over the entire surface of the surface to be dried, a wide range of water droplets can be moved even with a narrow air jet. The drying device can be downsized.

[0050] Further, a combination of periodic movement in which the moving means is reciprocated periodically in a substantially constant direction and progressive movement in which the periodic movement is moved in a predetermined direction, the jet contact area is determined to be a surface to be dried. You may make it move over substantially the whole surface. As a result, the water droplets adhering to the surface to be dried are blown off in a single linear movement similar to the trajectory of the periodic movement in the form of a line or a band, and are blown out by repeating the periodic movement while being innovatively moved. It is possible to expand and finally blow off the adhered water on the entire surface to be dried.

[0051] Furthermore, the moving means is gradually moved from the outer periphery of the surface to be dried toward the approximate center of the surface to be dried while being periodically moved on a substantially tangential line around the center of the surface to be dried. You may make it do. As a result, the air jet gradually moves toward the center while periodically moving in the tangential direction of the outer periphery of the water droplets adhering to the surface to be dried, so that the water droplets move toward the center of the surface to be dried and diffuse outward. The wet area does not spread.

[0052] Furthermore, the direction of periodic movement of the moving means is the left-right direction of the drying device, and the direction of progressive movement is the front-rear direction, whereby water droplets adhering to the surface to be dried are centered from the front side or the rear side. Can be easily collected.

[0053] Furthermore, by setting the direction of periodic movement of the moving means as the front-rear direction of the drying device and the direction of progressive movement as the left-right direction, water droplets adhering to the surface to be dried can be centered from the left or right side. Can be easily collected.

[0054] Further, the first step of moving the moving means gradually from the predetermined position ahead of the center of the surface to be dried toward the substantially center with the direction of the periodic movement of the moving means as the left-right direction of the drying means, A second step that gradually moves from a predetermined position behind the center of the drying surface toward the center, and the first step and the second step are executed in combination. As a result, water drops adhering to the front from the center of the surface to be dried move in the center direction by the first step, and water drops adhering to the rear from the center of the surface to be dried are centered by the second step. Since it moves in the direction, the entire water droplets adhering to the surface to be dried can be collected from the front and back to the center.

[0055] Furthermore, the direction of the periodic movement of the moving means is the front-rear direction of the drying apparatus, and a first step that gradually advances from a predetermined position on either side of the drying surface toward the center from the center of the surface to be dried; And a second step that gradually moves from the center of the surface to be dried toward the center of the predetermined position force on the left and right. The first step and the second step are executed in combination. As a result, water droplets adhering to either the left or right side of the center of the surface to be dried move in the center direction by the first step, and water droplets adhering to the other side move in the center direction by the second step. All water droplets adhering to the surface to be dried can be collected in the center from the left and right.

[0056] Further, a first step of moving the moving means gradually from the predetermined position ahead of the center of the surface to be dried toward the center with the direction of the periodic movement of the moving means as the left-right direction of the drying device, and the surface to be dried The second step of progressive movement from a predetermined position behind the center of the screen toward the center, and the direction of the periodic movement of the moving means as the front-back direction, from the center of the surface to be dried toward the center from either of the predetermined positions A third step of progressively moving, and a fourth step of moving progressively from the center of the surface to be dried from a predetermined position on the left and right sides toward the center, from the first step to the fourth step Are executed in combination. As a result, water droplets adhering forward from the center of the surface to be dried move in the center direction by the first step, and water droplets adhering behind the center of the surface to be dried are moved in the center direction by the second step. Water droplets that adhere to either the left or right side of the surface of the surface to be dried move in the center direction by the third step, and water droplets that adhere to the other side of the surface to be dried move to the center direction by driving in the fourth step. Since it moves, all the water droplets adhering to the surface to be dried can be collected from the front, back, left and right in the center.

[0057] Furthermore, the direction of the periodic movement of the moving means is the left-right direction of the drying device, and starts to gradually move from a predetermined position ahead of the center of the surface to be dried toward the center, passes through the center, By combining a step that moves gradually to a predetermined position behind the center, it is possible to apply an air jet to the entire water droplets adhering to the surface to be dried. If this step is performed after collecting water droplets on the surface to be dried in the center, It becomes easy to blow off water drops.

[0058] Furthermore, the moving means includes a driving means that moves or / and rotates the air ejection section, thereby moving the air ejection section in either the front, rear, left, or right direction, and the air ejection section. By using drive means that rotate in a substantially vertical or substantially horizontal direction, either alone or in combination, it is possible to carry out periodic and progressive movements of the moving means that moves the jet contact area. The contact range can be moved over the entire surface.

[0059] Furthermore, the drive means includes a swinging means for swinging the jet flow from the air jet section in the left-right direction, and an advancing / retreating means for reciprocating the air jet section in the front-rear direction. It is possible to move the contact area in the left-right direction by the swinging means and to move in the front-rear direction by the advancing / retreating means, and the contact area of the jet can be moved over the entire surface to be dried.

[0060] Furthermore, a toilet seat that can be seated, washing water jetting means for jetting washing water to a local body part, and a sanitary washing device provided with the drying device, so that water droplets are widely attached by washing. The air jet from the air blowing part is moved forward, backward, left, and right with respect to the drying surface, and the water droplets are collected and blown off at the center of the surface to be dried, so that the water drops can be efficiently dried in a short time without spreading around. Can do. In addition, water droplets can be blown away with a small air jet, so the drying device can be made smaller and the entire sanitary washing device can be made smaller.

[0061] Furthermore, by providing a heating means for heating the gas and a hot air outlet for blowing out the warm air heated by the heating means, compressed air is jetted onto the surface to be dried by the air blowing portion. In addition to blowing off the sprayed water droplets, the surface to be dried can be efficiently dried in a shorter time by blowing hot air heated by the heating means toward the surface to be dried. In addition, moisture on the surface to be dried can be removed by warm air, improving comfort after drying. Furthermore, the feeling of cold wind due to the jet of pressurized air can be prevented.

[0062] The following modes are also effective.

The present invention relates to a drying apparatus that dries with a jet of pressurized air having a narrower contact range than the surface to be dried, and an air jet part that injects pressurized air, and a contact range of the jet from the air jet part Is provided with a moving means for sequentially moving the film over substantially the entire surface to be dried.

[0063] This is because when a jet of pressurized air is applied to water droplets adhering to the surface to be dried, the water droplets are likely to blow off if the jet hits the direct or the vicinity. Therefore, the abutting range of the jet is sequentially sprayed over the entire surface to be dried against water droplets spreading and adhering to the surface to be dried.

[0064] Even with a jet of pressurized air whose contact area is narrowed down, water droplets adhering to a wide range of surfaces to be dried can be efficiently blown off, and the size of the drying apparatus can be reduced.

[0065] Further, in particular, in the above configuration, the moving means may move the jet contact area to the center while rotating around the periphery of the surface to be dried.

[0066] With this, for the water droplets spread and adhered to the surface to be dried, the contact range of the jet is circulated from the peripheral portion to the central portion from the peripheral portion of the surface to be dried, and moved to the central portion while reducing the circulatory range. As a result, the water droplets are blown off from the peripheral part toward the central part, and finally all the water drops collected in the central part can be blown off, so even a jet of pressurized air with a narrowed contact range can be used. Water droplets that adhere to a wide range of surfaces to be dried can be efficiently blown away, and the size of the drying device can be reduced.

[0067] Further, in the above configuration, the moving means has a central portion of the surface to be dried while circling a substantially polygonal shape formed by a substantially tangential line of the circumference centered on the center of the surface to be dried. By moving to the center, the contact area of the jet moves from the outer periphery of the surface to be dried over the polygon, and gradually approaches the center while the polygonal shape gradually decreases. It moves in the direction of the center of the film and is not diffused to the outside so that the wetted area does not spread. Also, if water droplets collect at the center of the surface to be dried, the air jet can be concentrated and applied to a narrow area, so that the water droplets can be efficiently blown away.

[0068] Further, in the above-described configuration, the moving means moves the jet contact area to the center of the surface to be dried while circling substantially on the circumference around the center of the surface to be dried. Since the entire water droplets adhering to the surface can be gathered at the center so that the diameter of the circumference is gradually reduced from the outer periphery to wrap the water droplets, the water droplets can be efficiently dried without spreading outward.

[0069] The present invention also provides a seatable toilet seat, wash water jetting means for jetting wash water, Any force of ~ 4 By adopting a sanitary washing device equipped with the drying device of one invention, a jet of pressurized air circulates from the periphery of the surface to be dried against the surface to be dried on which water droplets are widely adhered by washing. However, since it is moved to the center, a jet flows over the entire surface to be dried, and drying can be performed efficiently in a short time. Moreover, since water droplets can be blown off even with a small amount of air and air jet, the drying device can be made smaller and the entire sanitary washing device can be made smaller.

[0070] In addition, in the above configuration, a heating unit that heats the air and a hot air outlet that blows out the warm air heated by the heating unit are added to the surface to be dried by the air blowing unit. In addition to blowing compressed air and blowing water droplets, the surface to be dried can be efficiently dried in a shorter time by blowing warm air heated by the heating means toward the surface to be dried. In addition, moisture on the surface to be dried can be removed by warm air, improving comfort after drying. Furthermore, the feeling of cold wind due to the jet of pressurized air can be prevented.

[0095] The drive means 52 shown in FIG. 5 includes a drying nozzle 20, a swinging means 70 that swings the air jet from the drying nozzle 20 in the left-right direction, and an advancing / retreating drive means 71 that reciprocates the air jet in the front-rear direction. The driving means 52 is a moving means for arbitrarily moving the contact range of the pressurized air sprayed from the drying nozzle 20 to the surface to be dried over the entire surface to be dried. Can do.

[0096] The drying nozzle 20 has a cylindrical shape, and is provided with an air nozzle hole 21 and a cleaning water nozzle hole 22 in the cylindrical circumferential direction near the tip, and an air cavity 23 that guides pressurized air to the air nozzle hole 21 therein. A water cavity 24 for guiding the cleaning water to the cleaning water nozzle hole 22 is provided. That is, the drying nozzle 20 is also configured as a cleaning nozzle portion 33.

[0097] The pressurized air from the air pump 51 is connected to be supplied from the air tube 25 to the air cavity 23, and the wash water from the switching valve 32 is supplied from the water tube 26 to the water cavity 24. It is connected to the. The air tube 25 and the water tube 26 are made of a soft material such as rubber because a twisting or bending force acts when the drying nozzle 20 rotates or drives back and forth.

[0098] The base 55 is disposed with the drying nozzle 20 tilted along a rail portion 56 that is tilted forward on the upper surface, and is held through the drying nozzle 20 in a guide portion 57 that is disposed by opening a hole in the tip of the base. To do. The guide portion 57 is made of a material having good slidability, and has an appropriate clearance so that the drying nozzle 20 rotates and slides smoothly.

The front / rear drive motor 53 is arranged at the rear part of the base 55, and the rail part 56 The screw part 59 arranged in parallel to is connected to rotate forward and backward. This screw 59 The slider 58 is set on the nut portion 60 of the slider 58, and the slider 58 drives on the rail portion 56 as the screw portion 59 rotates. Therefore, the drying nozzle 20 held by the slider 58 is driven back and forth in accordance with the rotation of the front / rear drive motor 53. Here, the forward direction represents the A direction in FIG. 5, the rear direction represents the B direction, the front direction corresponds to the front surface direction of the passenger seated on the toilet seat 400, and the rear direction is used.

[0100] The swinging means 70 as the second moving means includes a left and right drive motor 54, a gear A61, a gear B62, and a gear C63 arranged on the slider 58, and the rotation of the left and right drive motor 54 is changed to the gear A 61 and the gear B62. And to the drying nozzle 20 via the gear C63. Accordingly, the drying nozzle 20 rotates in accordance with the forward / reverse rotation of the left and right drive motor 54, and the air jet ejected from the air nozzle hole 21 swings to the right and left of C and D in FIG.

[0101] Hereinafter, the control operation in the control unit 150 will be described with reference to FIG. 6, FIG. 7, FIG. 8, and FIG. FIG. 6 is a time chart of control operations in the “wet washing” and “drying” operations by the control unit 150, and FIG. 7 is a schematic cross-sectional view of the “wet washing” and “drying” operation states. 8 and 9 are schematic diagrams showing the movement pattern of the jet contact area E on the surface to be dried in the “dry” operation state.

[0102] As shown in FIG. 6, at the time of TO in a state where the operation has not yet been performed, the front and rear direction of the drying nozzle 20 (cleaning nozzle portion 33) is arranged at the rear end storage position. The horizontal direction of the drying nozzle 20 is set at an angle to a detection position of a position sensor (not shown) that detects the center position provided on the swinging means 70. This angle becomes the central angle, and the jet angle of the air nozzle hole 21 and the cleaning water nozzle hole 22 is set upward.

[0103] In T1, when the user depresses the bottom switch 303 of the remote control device 300, the open / close valve 34 opens, and tap water flows into the hot water heating means 31, and a built-in flow sensor (not shown) When detected, energization of the hot water heating means 31 is started, and the heated hot water starts to be supplied. At this time, since the switching valve 32 is set in the flow path on the toilet bowl side, the hot water, hot water, and hot water are discharged into the toilet bowl 600.

[0104] At the time T2 when the temperature of the hot water from the hot water heating means 31 reaches a predetermined temperature (for example, 36 ° C), the front / rear drive motor 53 is operated so that the cleaning nozzle section 33 is positioned at the central position (for example, the front side). Advance to 100mm). Then, at T3, the washing water is washed by the switching valve 32. Switch to the part 33 side, and spray cleaning water onto the user's surface to be cleaned. Electric power control to the hot water heating means 31 is performed using known PID or FF control so that the temperature detected by a temperature sensor (not shown) for detecting the tapping temperature becomes a set temperature (for example, 40 ° C.). The flow rate of the washing water is set to a user's preferred amount by adjusting the valve opening degree of the switching valve 32. As shown in Fig. 7 (a), the wet surface of the surface to be cleaned in this butt cleaning causes water droplets flowing only at the center where the cleaning water is directly applied to wet the periphery.

[0105] At the time T4 in Fig. 6 when the user finishes the butt washing and presses down the stop switch 305 of the remote control device 300, the washing water is switched to the toilet 600 side by the switching valve 32, and washing from the washing nozzle section 33 is performed. At the same time as stopping the water ejection, the energization to the hot water heating means 31 is stopped, and the forward / backward drive motor 53 is reversed to move the cleaning nozzle 33 back to the storage position. At T5, the on-off valve 34 is closed to shut off the water flow, and the cleaning operation is completed.

[0106] In the present embodiment, the operation in the buttocks cleaning has been described. However, even in the case of bidet cleaning in which the bidet switch 306 is pressed down on the remote control device 300 or the stimulus cleaning in which the stimulus switch 304 is pressed down, The sea case is the same. However, in the case of bidet cleaning, the cleaning nozzle position and flow rate setting corresponding to the bidet are changed, and in the case of stimulus cleaning, the cleaning nozzle unit 33 should be squeezed back and forth when the cleaning water is ejected from the cleaning nozzle unit 33. Driving operation is added.

[0107] Next, when the user depresses the drying switch 307 of the remote control device 300 at T6, the air fan 41 and the heater 43 are operated to start control for blowing hot air from the hot air outlet 42. . The hot air temperature blown out is controlled to an appropriate temperature by feedback-controlling the amount of current supplied to the heater 43. Then, air is blown from the hot air outlet 42 to substantially the entire surface to be dried, which is the user's cleaning surface.

At the same time, the air pump 51 is operated for a short time (for example, 1 second), and the pressurized air is blown out from the air nozzle hole 21 of the dry nozzle 20 for a moment. This operation prevents the user from reattaching the water droplets by blowing off the water droplets adhering to the surface of the drying nozzle 20 with the drying nozzle 20 in the storage position. If the pressurized air is instantaneously ejected from the air nozzle hole 21 of the drying nozzle 20 with the drying nozzle 20 in the stowed position, the drying nozzle 20 is efficiently dried by the reflected air from the wall surface. Is done. [0109] After that, the front / rear drive motor 53 is operated to advance the drying nozzle 20 to the most advanced position (for example, 150 mm forward), and the left / right drive motor 54 is operated to change the left / right angle of the drying nozzle 20 to the right end angle (for example, Change the angle to + 50 °).

[0110] At T7, the operation of the air pump 51 is started, and the injection of pressurized air from the air nozzle holes 21 to the surface to be dried is started.

[0111] In the first step from T7 to T8, the driving direction and the driving speed of the left and right driving motors 54 and the front and rear driving motors 53 of the driving means 52 are controlled, and the front and rear driving of the drying nozzle 20 is controlled within a predetermined range (for example, The reciprocating operation is performed at a high speed at 50mm to 150mm forward, and at the same time, the left and right angle of the drying nozzle 20 is slowly driven from the right end angle to the right angle (for example, + 50 ° to + 20 °) toward the center angle. In the operation of the first step, the air jet from the drying nozzle 20 gradually approaches the center while moving at a high speed in the front-rear direction from a predetermined position on the right side of the surface to be dried of the user. Therefore, as shown in the operation pattern P1 in FIG. 8, the contact area E of the air jet reciprocates at high speed in the tangential direction of the right end of the surface F to be dried, and gradually moves gradually toward the center G while periodically moving. Therefore, the zigzag movement trajectory is drawn as shown in the figure. As a result, as shown in FIG. 7 (b), the water droplets spreading and adhering to the right side of the surface to be dried can be blown away while being collected in the direction of the center.

[0112] At T8 in Fig. 6, the air pump 51 is temporarily stopped, and the left and right angles of the drying nozzle 20 are changed to the left end angle (for example, 50 °). At T9, the operation of the air pump 51 is restarted and the injection of pressurized air is started.

[0113] Then, in the second step from T9 to T10, the back-and-forth driving of the drying nozzle 20 is reciprocated at a high speed within a predetermined range (for example, 50 mm to 150 mm forward) as in the first step, and at the same time, the drying nozzle 20 The left and right angles are slowly driven from the left end angle toward the center angle from the left end angle to a predetermined left angle (for example, -50 ° force-20 °). The operation of this second step is that the air jet from the drying nozzle 20 gradually moves to the center while periodically moving the predetermined distance force on the left side of the user's surface to be dried in the front-rear direction. Approaching. Therefore, as shown in operation pattern P2 in FIG. 8, the contact area E of the air jet gradually moves toward the center G while periodically moving in the tangential direction of the left end of the surface F to be dried. As shown in the figure, a zigzag movement trajectory is drawn. As a result, Fig. 7 (C As shown in (), water droplets spreading and adhering to the left side of the surface to be dried can be blown away with a force S collected in the direction of the center.

[0114] The water droplets remaining on the surface to be cleaned by the first step and the second step described above remain only around the center. If there are residual water droplets collected in the center here, they are efficiently dried by the hot air blown from the hot air outlet 42.

[0115] Since the buttock of the human body has convex portions on both the left and right sides of the washing center of the anus and penis, both the left and right sides are lower than the washing center when sitting on the toilet seat. Therefore, if the cleaning water gets wet from side to side or is immediately dried, if the air jet is first applied to the center, the adhering water droplets spread from side to side and the wet area increases. As described above, the first step and the second step blow off water droplets while preventing the water droplets on the surface to be cleaned from spreading from side to side, so that efficient drying can be achieved. In the first and second steps, the advancing / retreating driving means 71 as the first moving means moves and sweeps the air ejection hole 22 along the cleaning center portion while maintaining the ejection angle, so that the user can Water droplets can be removed so that the water droplets attached to the buttocks are collected in the center of the circulating airflow. Therefore, not only does the cleaning water droplets adhering to the surface to be cleaned spread more than necessary, but also the water droplet removal efficiency can be increased by collecting the cleaning water droplets in one place.

[0116] At the end time T10 of the second step, the drying nozzle 20 is advanced to the most advanced position.

Then, in the third step of T10 force T11, the back-and-forth drive of the drying nozzle 20 is slowly retracted from the most advanced position toward the center, and at the same time, the left-right angle of the drying nozzle 20 is reciprocated at high speed from the right end angle to the left end angle. Let The operation of the third step is that the air jet from the drying nozzle 20 moves from the predetermined position in the front to the rear gradually while moving to the left and right at high speed on the surface to be dried. Approaching. Therefore, as shown in the operation pattern P3 in FIG. 9, the contact area E of the air jet gradually moves toward the center G while performing periodic movement that reciprocates at high speed in the tangential direction of the tip of the surface F to be dried. Since it moves gradually, a zigzag movement trajectory is drawn as shown in the figure. As a result, water droplets remaining in front of the central portion G of the surface to be dried can be blown away while being collected in the central portion G direction.

[0117] At T11 in FIG. 6, the air pump 51 is temporarily stopped, and the position in the front-rear direction of the drying nozzle 20 is moved to the rear predetermined position (for example, 50 mm forward). And at T12, the air pump The operation of 51 is restarted and the injection of pressurized air is started.

[0118] Then, in the fourth step from T12 to T13, the drying nozzle 20 is moved forward and backward slowly from the rear predetermined position toward the center, and at the same time, the right and left angle of the drying nozzle 20 is increased from the right end angle to the left end angle. To reciprocate. The operation of this fourth step is that the air jet from the drying nozzle 20 does not move at high speed in the left-right direction on the surface to be dried. ¾Slowly approaches the center from the predetermined distance to the front. Come on. Therefore, as shown in operation pattern P4 in FIG. 9, the contact area E of the air jet gradually moves toward the center G while periodically moving in a tangential direction at the rear end of the surface F to be dried. As it moves gradually, a zigzag movement trajectory is drawn as shown in the figure. As a result, water droplets remaining behind the center G of the surface to be dried can be blown away while collecting in the center G direction.

[0119] Water droplets remaining on the surface to be dried by the above first to fourth steps are only in the center.

[0120] The action on water droplets adhering to the surface to be dried in the first to fourth steps will be described.

Since the driving direction of the air jet to the surface to be dried during the operation of each step is sufficiently faster than the moving speed toward the center, the moving speed in the tangential direction with respect to the center is sufficiently faster. The air flow direction that spreads by colliding with the surface to be dried increases the flow component in the direction perpendicular to the substantially tangential direction. Therefore, the water droplets adhering between the air jet driven in the substantially tangential direction and the center portion are pushed by the air flow perpendicular to the tangential direction and move in the center portion direction. As the air jet gradually approaches the center, it gathers in the direction of the center. By performing this movement in the first to fourth steps in the four directions of right, left, front, and rear, the water droplets gather at the center.

[0121] At T13, the air pump 51 is stopped again, and the position of the drying nozzle 20 in the front-rear direction is moved to a predetermined position ahead (for example, 130 mm forward). At T14, the operation of the air pump 51 is restarted and injection of pressurized air is started.

[0122] Then, in the fifth step of T15, the T14 force is also driven in the forward / backward direction of the drying nozzle 20 by starting a predetermined position force forward, passing through the central portion, and passing through the central portion at a predetermined distance (for example, forward) Retreat slowly up to 50mm). At the same time, the drying nozzle 20 is reciprocated at high speed from the right end angle to the left end angle. The operation of this fifth step is dry nose While the air jet from No. 20 moves periodically on the surface to be dried in a horizontal direction at high speed, the air jet gradually moves backward from a predetermined position in the front to approach the center, and further approaches the center. Passes through the part and gradually moves to a predetermined rear position. Therefore, the position where the air jet strikes the surface to be dried gradually moves from the front through the center to the rear, so that the water droplets remaining at the center of the surface to be dried can be completely blown away.

[0123] At T15, the air pump 51 is stopped, and the drying nozzle 20 is moved to the rear end storage position in the front-rear direction. The horizontal direction of the drying nozzle 20 is returned to the center angle. Then, at T16 where the user depresses the stop switch 305 of the remote control device 300, the operation of the air fan 41 and the heater 43 is stopped, and the hot air is blown out from the hot air outlet 42.

[0124] As described above, in the present embodiment, when the air jet from the drying nozzle 20 is sprayed onto the surface to be dried, the warm air is blown from the hot air outlet 42 onto the surface to be dried. Thus, the air can be dried more efficiently and the cold air feeling of the air jet can be prevented.

[0125] In addition, because wet washing, bidet and drying are configured with a single nozzle and the drive means is shared, the installation area of the nozzle can be reduced and the number of parts can be reduced, resulting in space saving and low cost. Can be realized.

[0126] Further, since the pressurized air for drying is jetted from a single nozzle hole, the flow velocity of the air jet can be increased even at a low flow rate, and high drying performance can be obtained even with a small capacity air pump. It is done. That is, since the jet flow velocity is high, the energy for peeling off the water droplets when the jets hit the water droplets adhering to the surface to be dried increases, so that the water droplets can be efficiently blown off.

[0127] In this embodiment, the force of performing the butt washing and the bidet with the same nozzle hole may be configured by arranging a single nozzle hole in each cylinder, or the butt washing and the bidet. Independent nozzles and driving means may be arranged.

[0128] In the present embodiment, cleaning and drying are configured by a single cylinder and the driving means is shared. However, this may be configured by independent nozzles and driving means, respectively.

[0129] Furthermore, in this embodiment, the drying nozzle is configured with a single nozzle hole, but it may be configured to inject pressurized air through a plurality of nozzle holes, and a plurality of drying nozzles and driving means may be used. You may arrange. And water droplets on the surface to be dried are collected in the center by a plurality of air jets. The driving time can shorten the drying time. In this embodiment, the force of pressurized air is set to 20 to 30 m / s. To obtain the effect of blowing water droplets, a minimum of 10 m / s is required, and the setting element for the size of the jet contact area. The size of the nozzle holes and the number of nozzle holes must be selected considering the air pump capacity and the flow rate of the pressurized air.

[0130] In the present embodiment, the entire drying nozzle is driven by the driving means as the moving means. However, the present invention is not limited to this. Only the air nozzle holes of the drying nozzle or peripheral members including the air nozzle holes are not limited thereto. It is also possible to move the jet contact area by changing the jet direction by moving only the angle or changing the angle, or by providing wind direction changing means to change the jet direction in front of the air nozzle Etc. are considered

[0131] Further, in the present embodiment, the force that sequentially executes the first step to the fifth step may be repeatedly executed, or the order of the steps may be changed. Also, the first and second steps may be omitted, and the third and fourth steps may be omitted.

[0132] Further, the remaining water droplets can be surely removed by moving gradually through the center of one end of the surface to be dried while moving periodically at the end of the drying step.

[Embodiment 2]

Next, a sanitary washing device according to a second embodiment of the present invention will be described.

The sanitary washing device according to the second embodiment differs from the sanitary washing device according to the first embodiment in the following points.

FIG. 10 is a partial perspective view of the drying nozzle and the swinging means of the drying device in the sanitary washing device according to the second embodiment.

[0136] The swinging means 80 shown in FIG. 10 is rotatable about a rotation shaft 83 that is integrally connected to a base 82 of a dry nozzle 81 that is an air ejection portion, and an axis 84 of the rotation shaft 83. A left and right drive motor 86 for rotating the rotary shaft 83, and a gear A87 and a gear B88 for transmitting the rotational force of the left and right drive motor 86 to the rotary shaft 83.

[0137] The longitudinal drive function by the slider 85 is the same as that of the first embodiment, and the nut portion 60 is configured in the same manner. [0138] The internal configuration of the drying nozzle 81 has a cylindrical shape as in the first embodiment, and is provided with an air nozzle hole 21 and a washing water nozzle hole 22 in the cylindrical circumferential direction near the tip, and pressurized air inside. An air cavity (not shown) for air and a water cavity (not shown) for cleaning water are provided. The difference from the first embodiment is that the base 82 of the drying nozzle 81 is integrally connected to the rotating shaft 83, and the drying nozzle 81 reciprocally swings in a fan shape around the rotating shaft 83. .

[0139] In the above configuration, the air jet is driven left and right by controlling the forward / reverse rotation of the left and right drive motor 86 and rotating the drying nozzle 81 to a predetermined angle, thereby positioning the air nozzle hole 21 itself. Is moved to a predetermined position on the left and right.

[0140] Since the air jet 89 from the air nozzle hole 21 is jetted while being kept substantially perpendicular to the surface to be dried, the peeling action on water droplets adhering to the surface to be dried is enhanced. In addition, since the action of the water droplets trying to move to the outside of the surface to be dried can be further suppressed, the water droplets can be easily collected at the center. Furthermore, even if the air jet is moved to the left and right, the distance until the jet hits the surface to be dried is not separated, so a jet with a high air velocity can be applied to the surface to be dried, further improving the water droplet removal capability. it can.

[0141] (Embodiment 3)

Next, a sanitary washing device according to a third embodiment of the present invention will be described.

The sanitary washing device according to the third embodiment is different from the sanitary washing device according to the first embodiment in the following points.

[0143] Fig. 11 is a time chart of control operations in "wet washing" and "drying" operations by the control unit of the sanitary washing device. FIG. 12 is a schematic diagram showing the movement pattern of the contact area of the air jet on the surface to be dried in the “dry” operation state.

[0144] In the third embodiment, during the period from T7 to T13 in Fig. 11, the outer periphery of the surface to be dried F shown in Fig. 12 is rear ml, left m2, front m3, right m4, and rear m5. The abutting range E of the air jet is moved in order, and the driving range is gradually brought closer to the center G.

[0145] Specifically, in T7 to T8 in Fig. 11, the front-rear drive of the drying nozzle 20 is determined in the rear direction by linking the operation direction and operation speed of the left-right drive motor 54 and the front-rear drive motor 53 of the drive means 52. It moves at high speed in the range (eg 150mm to 50mm forward) and at the same Drive the left and right angles of the znore 20 slowly from the right end angle to the left (for example, + 50 ° to + 45 °).

[0146] Next, from T8 to T9, the back-and-forth drive of the drying nozzle 20 is slowly moved forward by a predetermined distance (for example, from 50 mm to 55 mm forward), and at the same time the left and right angles are moved to the left side within a predetermined angle range (for example, from + 45 °). Drive up to 50 °).

[0147] Next, from T9 to T10, the dry nodule 20 is moved forward in a predetermined range (for example, from 55mm to 1mm forward).

It moves at high speed (up to 50mm), and at the same time the left and right angles are to the right (for example, -50 ° force)

-45 °) Drive slowly.

[0148] Next, from T10 to T11, the drying nozzle 20 is slowly moved backward by a predetermined distance (for example, 150mm to 145mm forward), and at the same time the left and right angle is within a predetermined angle range (for example, from -45 ° to + 45 °). Drive at high speed.

[0149] Further, from T11 to T12, the dry nose 20 is moved rearward at a high speed within a predetermined range (for example, from 145mm to 55mm forward), and the simultaneous left / right angle is shifted to the left (for example, + 45 ° to + 40 °). ) Drive slowly.

[0150] While repeating the above operation, the predetermined range and the predetermined angle range are gradually reduced to bring the contact area of the air jet closer to the center G of the surface to be dried.

[0151] With this method, it is possible to blow off water droplets that continuously spread on the surface to be dried without stopping the air pump while collecting them in the center. Therefore, there is no waste in operation and the drying time can be shortened.

[0152] (Embodiment 4)

Next, a sanitary washing device according to a fourth embodiment of the present invention will be described.

The sanitary washing device according to the fourth embodiment differs from the sanitary washing device according to the first embodiment in the following points.

[0154] Fig. 13 is a time chart of the control operations in "wet cleaning" and "drying" operations by the control unit of the sanitary washing device. FIG. 14 is a schematic diagram showing the movement pattern of the contact area of the air jet on the surface to be dried in the “dry” operation state.

In the fourth embodiment, during the period from T7 to T13 in FIG. 13, the contact area E of the air jet is moved clockwise around the periphery of the surface to be dried F shown in FIG. Gradually its radius _r Is made smaller and closer to the center G.

[0156] Specifically, as shown in the longitudinal movement distance and the lateral angle of the drying nozzle 20 from T7 to T13 in Fig. 11, each reciprocates in a sinusoidal shape with respect to the center of the surface to be dried. Set the same reciprocating drive frequency and shift the phase by 90 degrees. That is, when the longitudinal movement distance is at the center position (T7, Τ9), the left-right angle is driven to the right or left end, and conversely, when the left-right angle is at the center angle (Τ8, T10 ) The front-rear movement distance is to drive the front end or rear end. Then, the amplitude of the reciprocating drive is gradually reduced to drive the jet movement range closer to the center G.

[0157] According to the present embodiment, the contact range of the air jet moves so as to draw a circle on the surface to be dried, so that the water droplets located inside the circle do not diffuse outside and are centered. It can be blown away while collecting. Accordingly, water droplets can be reliably removed, and there is no waste in operation, and the drying time can be shortened.

[0158] In the above-described embodiment, the contact area of the air jet is configured to draw a circle on the surface to be dried, but the contact area of the jet is a circle around the center of the surface to be dried. You may make it move to the center part of a to-be-dried surface, circling on the substantially polygon comprised by a substantially tangent. This simplifies the configuration of the drive means, and the jet contact area moves toward the center while gradually decreasing the polygonal shape while moving on the polygon from the outer periphery of the surface to be dried. As a result, the water droplets move toward the center of the surface to be dried and are not diffused to the outside so that the wetted area does not spread. Also, if water droplets gather at the center of the surface to be dried, the air jet can be concentrated and applied to a narrow area, so that the water droplets can be efficiently blown away.

[Embodiment 5]

Next, a sanitary washing device according to a fifth embodiment of the present invention will be described.

[0160] Also in the sanitary washing device according to the fifth embodiment, the surface to be dried F is swept by the air jet from the drying device to efficiently remove water droplets in the washing water adhesion range Α. It is. The sanitary washing apparatus according to the fifth embodiment is different from the sanitary washing apparatus according to the third and fourth embodiments in the following points.

FIGS. 15 and 16 are diagrams showing the relationship between the position of the drying nozzle 20 and the contact range. This Here, since the plan view is the same as that of the third embodiment, the plan view is omitted, but it is the same as FIG. That is, FIG. 12 moves in the same manner as the movement pattern of the contact area of the air jet on the surface to be dried in the operating state, but in this embodiment, when the air jet is controlled, the ejection of the drying nozzle 20 Instead of changing the direction, the position of the drying nozzle 20 is changed so that the tip position of the drying nozzle 20 is directly below the spray position. The position of point G in Fig. 12 corresponds to Fig. 15 (a) and Fig. 16 (a), ml corresponds to Fig. 15 (b) and Fig. 16 (c), and m2 corresponds to Fig. 15 (c) and Fig. 16 This corresponds to (c), m3 corresponds to FIG. 15 (c) and FIG. 16 (b), and m4 corresponds to FIG. 15 (b) and FIG. 16 (b).

[0162] In this configuration, the air jet is configured to be substantially perpendicular to the surface to be dried, and according to this configuration, the collided air flow follows the axis of the air jet along the surface to be dried. Spreads radially as the center. Due to the air flowing along the surface to be dried, water droplets adhering to the surface to be dried move or scatter in a direction away from the axis of the air jet. Therefore, the center position of this air jet is horizontally shifted from the position of Fig. 15 and Fig. 16 (a) to (b) (c) and then to ml, m2, m3, m4, and m5 in sequence as shown in Fig. 12. By moving, the attached water droplets are blown away while moving in the center G direction, so that drying proceeds efficiently.

[0163] However, when the air jet strikes at a slant that is not perpendicular to the surface to be dried, the collided air flow spreads centering on the direction where the spread angle is gentle, and the radial spread collapses. When the collision angle increases from the vertical angle, the collision air spreads only in the direction of a gentle angle and the spread decreases. In this way, when the air ejection direction is deflected back and forth and left and right and applied to the surface to be dried, the air jet impinging on the surface to be dried hits the surface of the air almost perpendicularly to the surface to be dried. At a position away from the force center, the air jet strikes against the surface to be dried. For this reason, there is no problem that the jet spreads in the center direction and the adhered water droplets spread outside the surface to be dried. In this embodiment, there is no such problem, and the drying is performed very efficiently as described above. Progresses.

[0164] In FIG. 16, the drying nozzle is inclined slightly forward so that it is averaged along the angle of the surface of the human buttock that is the surface to be dried. As a result, the distance between the dry nozzle and the surface to be dried can be made almost constant, so that the collision speed of the air jet is reduced. It is possible to perform efficient water droplet removal without fading.

[0165] The washing water adhesion range A is a range in which the water for washing the human body is spouted from the washing water jetting means and spreads with the momentum, or flows along the surface of the buttocks and spreads. Is set as the surface to be dried in the range equal to or wider than the washing water adhesion range. In this way, it is possible to prevent water droplets from spreading outside the surface to be dried by ejecting air from the outer periphery of the surface to be dried.

[0166] As described above, in the present embodiment, since it is configured to always inject in the vertical direction without changing the direction of the injection nozzle 20, drying can be performed efficiently.

[Embodiment 6]

Next, a sanitary washing device according to a sixth embodiment of the present invention will be described. In the present embodiment, the driving means 52 described in the first embodiment is added to the advancing / retreating driving means 71 as the first moving means for driving in the front-rear direction of the nozzle, and is orthogonal to the driving direction by the advancing / retreating driving means 71. Horizontal driving means 71R as second moving means for driving so as to move in a substantially linear motion in the direction in which it moves.

FIG. 17 is a perspective view showing the configuration of the drive means 52 in the drying device 50. As shown in FIG. The forward / backward driving means 71 is formed in the same manner as in the first embodiment shown in FIG. 5, and the description thereof is omitted.

[0169] The driving means 52 shown in FIG. 17 includes a drying nozzle 20, an advance / retreat driving means 71 for reciprocating the air jet from the drying nozzle 20 in the front-rear direction, and a direction orthogonal to the drive direction of the advance / retreat driving means 71. A horizontal driving means 71R as a second moving means for driving so as to move substantially linearly, and a forward / backward driving means 71 and a base 55R for supporting the horizontal driving means 71R, the driving means 52 is moved. As a means, the force S can be moved so that the contact range of the pressurized air sprayed from the drying nozzle 20 with respect to the surface to be dried is swept across the entire surface to be dried.

[0170] The drying nozzle 20 has a cylindrical shape as in the first embodiment, and is provided with air nozzle holes 21 and cleaning water nozzle holes 22 in the cylindrical circumferential direction in the vicinity of the tip, and is supplied with compressed air. An air cavity (not shown) leading to the hole 21 and a water cavity (not shown) leading the cleaning water to the cleaning water nozzle hole 22 are provided. That is, the drying nozzle 20 also serves as a cleaning nozzle. It is configured.

[0171] The base 55R is arranged by inclining the horizontal driving means 71R along a rail portion 56 that is inclined forward on the upper surface. The drying nozzle is horizontally driven by sliding on a horizontal driving rail 56R provided in the horizontal driving means 71R. In addition, a slider 58 that slides along the rail portion 56 is provided on the upper surface of the base 55R, and the horizontal driving means 71R is fixed to the slider 58, and the horizontal driving means 71R is adapted to the rail portion according to the operation of the slider 58. Drive along 56. On the other hand, by sliding on the horizontal driving rail 56R provided in the horizontal driving means 71R with the slider 58R, the drying nozzle 20 can be moved horizontally in addition to the forward and backward driving.

[0172] The forward / backward driving means 71 as the first moving means is composed of the front / rear drive motor 53, the slider 58 and the screw part 59, and the horizontal driving means 71R as the second moving means is mounted on the slider 58. The horizontal drive motor 53 R is disposed in the middle portion of the base 55R, and the R on the rail 56 disposed so as to be orthogonal to the rail portion 56 is moved to the slider 58R. Are connected to move horizontally. The screw portion 59 is set on the nut portion 60 of the slider 58, and is driven so that the slider 58 slides on the rail portion 56 as the screw portion 59 rotates. The slider 58R is set on the nut portion 60R of the slider 58R, and the slider 58R drives on the rail portion 56R according to the rotation of the horizontal drive motor 53R. Therefore, the drying nozzle 20 held by the sliders 58 and 58R is driven forward and backward in accordance with the rotation of the front and rear drive motor 53 and the horizontal drive motor 53R, and is driven horizontally. Here, the forward direction represents the A direction in FIG. 17, the rear direction represents the B direction, the front direction corresponds to the front direction of the passenger seated on the toilet seat 400, and the rear direction is the passenger's front direction. Corresponds to the back direction. The horizontal direction is the direction connecting C 'and D'.

In this way, vertical and horizontal linear drive is possible.

[Embodiment 7]

Next, a sanitary washing device according to a seventh embodiment of the present invention will be described.

The present embodiment is a modification of the nozzle structure and is characterized in that the second moving means is configured to swing the jet direction of the jet jetted from the air jet section. That is, the driving means 52 described in the first embodiment is shown in FIGS. In addition to the forward / backward driving means 71 as the first moving means for driving in the front-rear direction of the nozzle, a self-excited oscillation fluid element 121 using the Coanda effect is provided as the second moving means. The air jet is movable in the lateral direction. FIG. 18 is a perspective view of the main part, and FIG. 19 is a cross-sectional view cut along a cross section including the air ejection hole 121C. The forward / backward drive means 71 is driven by a self-excited oscillating fluid element 121 in a direction perpendicular to the drive direction of the forward / backward drive means 71 so that the air ejection direction swings in the R and S directions.

FIG. 18 is a perspective view showing the main configuration of the drive means 52 in the drying device 50. FIG. The advance / retreat driving means 71 is formed in the same manner as in the first embodiment shown in FIG. 5, and is configured to move in the advance / retreat directions A and B. Although the explanation is omitted, the same reference numerals are assigned to the same parts.

[0175] This fluid element is formed inside the nozzle 120 and conveys pressurized air through the air cavity 123, and in the vicinity of the tip of the air cavity 123, a cross-sectional fan-shaped air injection hole communicating with the air cavity 123 121C and the narrow first and second feedback holes 121A, which are arranged symmetrically with respect to the center of the air injection hole 121C so as to open from the vicinity of the air cavity 123 to the vicinity of the opening end of the air injection hole 121C. It consists of B.

[0176] In this fluidic element, the jet jetted from the air cavity 123 to the air jet hole 121C tends to adhere to the wall surface 120A or 120B constituting the air jet hole 121C by the Coanda effect. The jet attached to the wall surface 120A is separated from the wall surface 120A by the flow from the feedback hole 121A and is attached to the wall surface 120B.

On the other hand, the jet attached to the wall surface 120B is separated from the wall surface 120B by the flow from the feedback hole 121B, and is attached to the wall surface 120A again.

[0178] Thus, the jet self-oscillates between the wall surfaces 120A and 120B.

By using this fluid element, it is possible to move the air ejection direction by self-excited oscillation without providing a separate drive source.

[0179] In this embodiment, this fluid element is used as the second moving means. However, in Embodiments 1 to 6, this fluid element may be added to the air ejection hole.ヽThereby, it becomes possible to dry more efficiently.

[0180] (Embodiment 8) Next, a sanitary washing device according to an eighth embodiment of the present invention will be described.

In the present embodiment, a configuration for removing water droplets adhering to Nozunore will be described.

When the drying process is started with water droplets attached to the nozzle after cleaning, the water droplets adhering to the nozzle may be blown off with the air ejected from the air injection holes and adhere to the surface to be dried. In the embodiment, a sanitary washing apparatus including means for removing water droplets attached to the nozzle will be described.

FIG. 20 (a) is a schematic view of the drying device 50 housed in the main body case 50C, and FIG. 20 (b) is an explanatory view showing the nozzle drying state.

When the cleaning is completed, the nozzle 20 once enters the storage position as shown in FIG. 20 (b).

[0182] At this time, in the state where the nozzle is housed in the nozzle housing case 21C, the air ejection hole

It is comprised so that air may be ejected from 21. The ejected air is reflected by the nozzle housing case 21C and the shirt 90, and blows off water droplets adhering to the outer periphery of the nozzle, thereby drying the nozzle surface.

[0183] When nozzle drying is completed in this way, the shirt 90 is opened, the dried nozzle advances from the nozzle storage case 21C, and enters the drying process by moving forward and backward near the surface to be dried.

Thus, drying can be performed efficiently.

[0184] It should be noted that this nozzle drying is also effective for removing water droplets after cleansing, which is performed only after washing the human body.

[0185] For example, when a person leaves the toilet room and no human body is detected by the human body detection means, cleaning water flows into the water channel for cleaning the nozzle at the cleaning nozzle for cleaning the nozzle. Is done. Then, the direction of the shatter 90 as the shielding means is shielded in the direction facing the toilet and the cleaning water is prevented from immediately falling into the toilet, and this washing water removes the dirt around the nozzle. Since the water around the Noznore 20 has been cleaned, it drops from the opening at the end of the folded portion of the shirt 90 into the toilet together with dirt, so there is no problem. In addition, the nozzle cleaning operation may be configured to be performed even after the cleaning nozzle is used. In this case, the nozzle is scattered during the defecation as well. Effective cleaning is possible even when dirty water or filth adheres.

[0186] Further, on the surface facing the nozzle 20 of the shirter 90, which is a shielding means, a groove that serves as a flow path or a rib that transmits water is provided so that the cleaning water can flow through the tiling water. If this is the case, it is possible to guide the cleaning water so that the cleaning water can efficiently flow around the nozzle.
