The present invention relates to a nozzle device for spraying washing water for washing a part of a human body, and a sanitary washing device equipped with the nozzle device, and particularly relates to the structure of the nozzle device.

Background technique

In the existing nozzle device, a pair of vortex chambers are provided below the ejection port, and a fluid oscillating element is used to periodically change the ejection direction of the cleaning water, thereby expanding the cleaning range and changing the ejection intensity, wherein the fluid The oscillating element self-oscillates the washing water by using the pressure difference generated by the water flow (for example, refer to Patent Document 1).

FIG. 12 is a schematic diagram showing a schematic configuration of the vicinity of the discharge port of the liquid oscillation nozzle described in Patent Document 1. FIG.

As shown in FIG. 12 , in the liquid oscillating nozzle described in Patent Document 1, a main nozzle 2 is connected to a water supply passage 1 , and the main nozzle 2 has a flow passage diameter reduced substantially perpendicularly to the water supply passage 1 . The main nozzle 2 communicates with the main water channel 3 having a flow channel diameter larger than that of the main nozzle 2 . An air inlet 6 for introducing outside air is provided on the upstream side of the main waterway 3 , and both sides of the main waterway 3 communicate with the detour waterway 4 . In addition, the downstream side of the main water channel 3 communicates with the discharge port 5, and the discharge port 5 is formed such that its opening gradually expands from the inlet side toward the outlet side.

The washing water flowing in from the water supply channel 1 flows into the main water channel 3 after passing through the main nozzle 2 , and is sprayed out from the spray port 5 . At this time, part of the washing water flowing into the main water channel 3 flows into a detour water channel 4 to generate a swirling water flow, so that the water flow of the washing water in the main water channel 3 is pulled to the side of a detour water channel 4, and the washing water sprayed from the spray port 5 also Equally be pulled toward a detour water channel 4 sides and spray. In this way, the flow velocity of the detour channel 4 on the side where the water is drawn increases, the pressure of the detour channel 4 on the side where the water is drawn increases, and the flow velocity of the other detour channel 4 decreases, thereby reducing the pressure. As a result, a pressure difference is generated between the detour water channels 4 , and the washing water in the main water channel 3 is pulled toward the other detour water channel 4 side and sprayed out. Next, by repeating the above-mentioned operation, the washing water can be automatically oscillated and vibrated to be sprayed from the spray port 5 .

In addition, by introducing outside air into the main water channel 3 through the air inlet 6 provided in the main water channel 3, the volume of washing water increases, and the effect of blocking the discharge port 5 increases. Thereby, the pressure difference between the bypass water channels 4 increases, and the oscillation can be further stabilized.

Contents of the invention

The problem to be solved by the invention

However, in the above-mentioned conventional structure, it is an essential component to provide two detour channels 4 for oscillating the washing water below the discharge port 5, so there is a problem that the front end portion of the nozzle becomes larger. In particular, there is a problem that it is extremely difficult to implement in a multi-function nozzle device in which a single nozzle is equipped with a plurality of discharge ports such as buttock washing and feminine washing, in addition to being enlarged and complicated in structure.

The present invention solves the above-mentioned conventional problems, and an object thereof is to provide a nozzle device and a sanitary cleaning device including the nozzle device, which can be easily implemented even with a composite nozzle with a small and simple structure, and can spray vibrating water streams.

means to solve the problem

In order to solve the above-mentioned conventional problems, the nozzle device according to the present invention includes a nozzle body in which: a main channel through which washing water flows; an outlet through which the washing water is sprayed; The discharge flow path communicated with the discharge port is provided with a stepped portion in the discharge flow path so that the cross-sectional area of the discharge flow path is smaller than the cross-sectional area of the main water channel. A pressure communication channel is provided outside the channel, and the pressure communication channel has: at least two gaps communicated with the main water channel; and a communication channel configured to communicate with the at least two gaps.

As a result, the washing water flowing from the main water channel into the discharge flow channel swirls at the stepped portion. Therefore, in the vicinity of the entrance of the discharge channel, part of the washing water is separated from the wall surface forming the discharge channel to become a water flow with increased pressure, and in addition, a part of the cleaning water adheres to the wall surface forming the discharge channel to become a pressure drop. of water flow. By generating a pressure difference, a secondary water flow is generated through the pressure communication channel from the high-pressure peeling side toward the low-pressure adhesion side. Then, by the action of the secondary water flow, the attached water flow is transferred to the detached water flow, and the pressure on the attached side rises to generate an opposite pressure difference. With the reversal of the pressure difference, a secondary water flow in the opposite direction is generated, and the pressure on the peeling side rises again. By repeating these operations, the movement of the attached part and the detached part occurs alternately, and the washing water flowing into the discharge channel can be oscillated (the washing water can be formed into an oscillating water flow).

In addition, since the discharge channel has a small cross-sectional area due to the stepped portion, it is possible to amplify the pulsation of the above-mentioned oscillating water flow. Therefore, the washing water jetted from the ejection port can be formed into a vibrating water flow (jet flow) with a strong pulsating feeling, and by repeatedly stimulating the user's skin sensation, the user can have a feeling of powerful washing.

Therefore, in the nozzle device of the present invention, the washing water jetted from the ejection port can be formed as a jet flow accompanied by the vibrating water flow, and the washing power can be improved, and the washing feeling can be improved. In addition, in the nozzle device of the present invention, the above-mentioned oscillating water flow with strong pulsation can be implemented by using the stepped portion and the pressure communication passage, so the nozzle device can be downsized with a simple structure.

In addition, the sanitary cleaning device of the present invention includes: the above-mentioned nozzle device of the present invention; a cleansing water supply member for supplying cleansing water to the nozzle device; a control member for controlling the nozzle device and the cleansing water supply member; toilet seat.

Thereby, it is possible to provide a sanitary washing device having a high cleaning power and a good cleaning feeling.

The above object and other objects, features, and advantages of the present invention will be clarified from the detailed description of the following preferred embodiments with reference to the accompanying drawings.

Detailed ways

The nozzle device of the present invention has a nozzle main body, and the nozzle main body is provided with: a main water channel for the circulation of cleaning water; a spray outlet for spraying cleaning water; A stepped portion is provided so that the cross-sectional area of the ejection channel is smaller than that of the main water channel, and a pressure communication channel is provided outside the ejection channel. The pressure communication channel has: at least two gaps; and a communication channel provided in a way to communicate with the at least two gaps.

Here, the cross-sectional area of the discharge channel refers to the cross-sectional area in the direction perpendicular to the flow direction of the washing water in the discharge channel. Similarly, the cross-sectional area of the main water channel refers to the cross-sectional area in the direction perpendicular to the flow direction of the washing water in the main water channel.

In addition, the communication channel is formed to communicate at least two gaps independently of the main water channel.

As a result, the washing water flowing from the main water channel into the discharge flow channel swirls at the stepped portion. Therefore, in the vicinity of the entrance of the discharge channel, a part of the washing water is separated from the wall surface forming the discharge channel to become a water flow with increased pressure, and another part of the cleaning water adheres to the wall surface forming the discharge channel to become a pressure flow falling water flow. By generating a pressure difference, a secondary water flow is generated through the pressure communication channel from the high-pressure peeling side toward the low-pressure adhesion side. Then, by the action of the secondary water flow, the attached water flow is transferred to the detached water flow, and the pressure on the attached side rises, thereby generating an opposite pressure difference. Based on the reversal of the pressure difference, a secondary water flow in the opposite direction is generated, and the pressure on the peeling side rises again. By repeating these actions, the attached parts and the peeled parts move alternately, and the washing water flowing into the discharge channel can be oscillated (washing water can be formed into an oscillating water flow).

In addition, since the discharge channel has a small cross-sectional area due to the stepped portion, it is possible to increase the amplitude of the above-mentioned vibrating water flow. Therefore, the washing water jetted from the ejection port can be formed into a vibrating water flow (jet flow) with strong pulsation, and the user can feel powerful washing by repeatedly stimulating the user's skin sensation.

Furthermore, in the nozzle device according to the present invention, the pressure communication path may be provided along the outer periphery of the discharge flow path.

Thereby, the pressure communication channel can be made to correspond to the pressure difference generated at all parts of the step portion, the vibrating water flow can be reliably generated, and the pressure communication channel can be implemented with a simple structure.

In addition, in the nozzle device according to the present invention, the pressure communication channel may be constituted by a gap provided along the outer periphery of the discharge flow channel and an annular pressure communication chamber communicating with an end of the gap.

Thereby, the pressure communication channel can be made to correspond to the pressure difference generated at all parts of the step portion, the vibrating water flow can be reliably generated, and the pressure communication channel can be implemented with a simple structure.

In addition, in the nozzle device according to the present invention, the discharge flow path may be formed in a stepped shape so that the cross-sectional area of the distal end portion is larger than the cross-sectional area of the base end portion.

As a result, when the cleaning water that has become the vibrating water flow flows through the discharge flow channel, a vortex is generated at the stepped portion (corner) of the discharge flow channel, thereby generating a pressure difference in the discharge flow channel, enabling cleaning The amplitude of the pulsation of the water is further increased, and the pulsation feeling can be further increased.

In addition, in the nozzle device according to the present invention, the discharge channel may be provided such that its axis is inclined 5 to 20 degrees toward the rear end side of the nozzle body with respect to the axis of the main water channel.

This makes it easier for the washing water to moderately peel off and adhere in the discharge flow channel, and it is possible to more stably generate the vibrating water flow, and further increase the vibration amplitude of the washing water.

In addition, in the nozzle device according to the present invention, the nozzle device may include a cylindrical nozzle cover covering at least a part of the nozzle body, the nozzle cover may be provided with a discharge opening, and the nozzle body and the nozzle cover may be configured to be slide.

As a result, when the washing water is sprayed, the nozzle body, especially the vicinity of the ejection port, is covered by the nozzle cover, and the nozzle body is less likely to be polluted by the washing water dirty by washing, which is hygienic.

In addition, in the nozzle device according to the present invention, a speed change unit may be provided in the middle of the main water channel, and the speed change unit may be configured to change the flow velocity of a part of the washing water flowing through the main water channel.

As a result, the washing water flowing through the main water channel breaks the balance of the flow velocity at the speed change unit, and is given a swirl component. Therefore, the washing water given the swirl component flows into the discharge flow path. Next, part of the washing water flowing into the discharge flow path flows so as to be separated from the wall surface forming the discharge flow path, and the other part flows so as to adhere to the wall surface. At this time, since the washing water is imparted with a swirl component, the detached part and the attached part move sequentially, and the oscillating water flow is more likely to be generated.

In addition, in the nozzle device according to the present invention, a bent portion bent at right angles and a bent portion having a curved surface may be provided in the middle of the main water channel, and the speed change unit may be composed of the bent portion and the bent portion.

Thereby, it is possible to more easily impart a swirl component to the washing water in the transmission unit.

In addition, the sanitation cleaning device according to the present invention includes: the nozzle device described above; a cleansing water supply member for supplying cleansing water to the nozzle device; a control member for controlling the nozzle device and the cleansing water supply member; and a toilet seat placed on the upper surface of the toilet. .

Thereby, it is possible to provide a sanitary washing device having a high cleaning power and a good cleaning feeling.

In addition, in the following description, the direction of the front-end part of a nozzle main body is called a front-end side, and the direction of a rear-end part is called a rear-end side.

As shown in FIG. 5( b ) and FIG. 6 , the nozzle body 300 is molded from a resin material, and the nozzle body 300 is formed of a nozzle body base material 301 , a nozzle cover member 302 , and a nozzle bottom member 303 . Specifically, the nozzle body 300 is formed by welding the nozzle cover member 302 and the nozzle bottom member 303 to the nozzle body base material 301, which is formed by combining the buttock washing channel 310 and the female-only washing channel 330. The nozzle cover part 302 is provided with a buttock washing outlet 320 and a female-specific washing outlet 340 , and the nozzle bottom part 303 forms the bending part 311 of the buttock washing flow channel 310 .

Inside the nozzle body 300 , two flow paths, namely a buttock washing flow path (main water path) 310 and a women's cleansing flow path 330 , are disposed approximately parallel to the axis of the nozzle body 300 . The buttock washing channel 310 is arranged at the lower part of the nozzle body 300 , and the female-only washing channel 330 is arranged at the upper part of the nozzle body 300 . Rear end portions of the buttock washing flow path 310 and the feminine cleansing flow path 330 are respectively connected to a buttock washing water supply port 319 and a feminine cleansing water supply port 339 through which the washing water supplied from the washing water supply member flows.

In addition, a buttock washing outlet (spray outlet) 320 is provided at the front end of the upper surface of the nozzle body 300 , and a female-only washing outlet 340 is provided at a rear end side of the buttock washing outlet 320 .

The buttock washing channel 310 is formed to extend from the rear end of the nozzle body 300 substantially parallel to the axis of the nozzle body 300 to the vicinity of the front end. A speed change unit 323 is provided in the middle of the buttock washing flow path 310 . In addition, the downstream end of the buttocks washing flow path 310 is connected to the buttocks washing discharge port 320 via the discharge flow path 312 . In addition, in the present first embodiment, the flow cross section of the buttock washing channel 310 is formed in a substantially circular shape, and the diameter thereof is formed in a range of about 3.0 to 3.5 mm. In addition, in the present first embodiment, the transmission portion 323 is constituted by the bent portion 311 and the curved portion 313 .

Here, the shape of the transmission portion 323 will be described in detail with reference to FIGS. 6 and 7 .

As shown in FIGS. 6 and 7 , the bending portion 311 is provided on one side of the buttock washing flow channel 310 and is formed to bend at right angles upward from the horizontal direction. Here, the right-angled shape means bending within a range of 70° to 100°.

The curved portion 313 has a concave curved surface, and the curved portion 313 is formed so that the washing water flowing through the buttock washing flow path 310 smoothly flows upward from the horizontal direction.

As a result, the speed change unit 323 changes the flow velocity of the washing water flowing through the buttock washing flow path 310 between the side where the bent portion 311 is provided and the other side where the curved portion 313 is provided, thereby imparting a swirling component to the washing water.

In addition, in the first embodiment, the speed change portion 323 has a form including the bent portion 311 and the bent portion 313 , but it is not limited thereto. The speed change unit 323 may be in any form as long as the flow velocity of a part of the wash water flowing through the buttock washing flow path 310 can be changed relative to the flow velocity of the other wash water. For example, an aspect in which the transmission portion 323 is formed of the curved portion 313 may also be adopted.

In addition, in the first embodiment, the bend portion 311 and the bend portion 313 are provided at the same position (the same position in the flow direction of the cleansing water) of the buttocks washing flow path 310, but they are not limited to this. A form in which the bent portion 311 and the curved portion 313 are provided at different positions of the buttock washing flow path 310 (different positions in the flow direction of the washing water) may also be adopted. That is, the bent portion 313 may be provided on the upstream side of the bent portion 311 or may be provided on the downstream side of the bent portion 311 . In this case, the curved portion 313 may be curved in a convex shape, or may be curved in a concave shape.

In addition, as shown in FIGS. 6 and 7 , the discharge channel 312 is formed in a stepped shape such that the flow cross-sectional area of the terminal portion 322 is larger than the flow cross-sectional area of the base end portion 321 . The base end portion (hereinafter referred to as the small hole portion) 321 is formed in a cylindrical shape with a diameter of approximately 1.5 to 1.7 mm, and the distal portion (hereinafter referred to as the large hole portion) 322 is formed in a cylindrical shape with a diameter of approximately 1.9 to 2.1 mm. In addition, here, although the discharge flow path 312 has adopted the form which consists of two stages of the small hole part 321 and the large hole part 322, it is not limited to this. The discharge channel 312 may be formed in a stepped shape as long as the flow cross-sectional area of the terminal portion 322 is larger than the flow cross-sectional area of the base end portion 321, and may be formed of multiple stages (for example, a small hole portion, a middle hole portion, and a large hole portion). hole) form.

The discharge channel 312 is provided such that its axis is inclined by about 7 degrees toward the rear end side of the nozzle main body 300 with respect to the axis of the buttock washing channel 310 . From the viewpoint of forming the washing water jetted from the buttock washing jet port 320 into a vibrating water flow (jet flow) with strong pulsation, it is preferable that the axis of the jetting flow path 312 is relatively close to the axis of the buttock washing flow path 310. It is inclined to the rear end side of the nozzle main body 300 by 5 degrees or more. In addition, from the viewpoint of spraying the cleansing water sprayed from the buttocks washing outlet 320 toward the user's local area, it is preferable that the axis of the spray flow channel 312 is directed toward the nozzle body with respect to the axis of the buttocks washing flow channel 310 . The rear end side of the 300 slopes just under 20 degrees.

Thereby, the washing water is easily peeled off from the wall surface on the rear end side of the small hole portion 321 and easily adhered to the front end side. Therefore, the balance of the water flow can be broken, and the vibrating water flow can be generated more easily.

In addition, the corner portion of the discharge channel 312 formed by the small hole portion 321 and the large hole portion 322 is formed in an edge shape that rises approximately at right angles. As a result, a vortex is generated at the corner portion of the discharge flow channel 312 formed by the small hole portion 321 and the large hole portion 322 , and separation of the water flow is likely to occur. That is, a part of the washing water sprayed from the small hole portion 321 to the large hole portion 322 adheres to the side wall of the large hole portion 322, and the other part of the washing water is peeled off from the side wall of the large hole portion 322, and a pressure difference is generated, thereby cause pressure changes. Therefore, the amplitude of the vibration of the washing water flowing through the large hole portion 322 can be further increased.

In addition, a stepped portion 314 is formed at a connection portion between the buttock washing flow path 310 and the small hole portion 321 of the discharge flow path 312 . That is, since the diameter of the small hole 321 is smaller than the diameter of the buttocks washing flow channel 310 , a step is formed at the connecting portion between the buttocks washing flow channel 310 and the small hole 321 , and this portion constitutes the stepped portion 314 .

A pressure communication channel 317 is provided outside the stepped portion 314 . The pressure communication channel 317 is formed by the gap between the nozzle body base material 301 and the nozzle cover member 302 , and is formed so as to surround the discharge flow channel 312 . In the first embodiment, the pressure communication channel 317 is composed of the gap 315 and the pressure communication chamber 316 .

The base end (upstream end) of the gap 315 is formed to communicate with the buttock washing flow path 310 , and the gap 315 is formed in an annular shape along the outer periphery of the discharge flow path 312 . That is, in the first embodiment, the gap 315 is also used as at least two opposing gaps provided to communicate with the buttock washing flow channel 310 and a communication channel provided to communicate with the at least two opposing gaps. . Further, the pressure communication chamber 316 communicates with the terminal end (downstream end) of the gap 315, and is formed in an annular shape. In addition, in the first embodiment, the pressure communication chamber 316 is configured such that its volume is larger than the volume 315 of the gap.

Thus, the high pressure applied from the buttock washing channel 310 to a specific portion of the stepped portion 314 is transmitted to a portion of the stepped portion 314 that is different from the specific portion (here, an opposing portion) via the pressure communication channel 317, thereby enabling Increase the pressure on this part. In addition, as will be described later, the pressure communication channel 317 only needs to have at least two gaps provided to communicate with the buttock washing flow channel 310 and a communication channel provided to communicate with the at least two gaps. The pressure communication channel 317 Various forms can be adopted.

As shown in FIG. 6 , the feminine cleansing channel 330 is formed to be approximately parallel to the axis of the nozzle body 300 with a channel diameter of approximately 3.0 to 3.5 mm from the rear end to the vicinity of the front end of the nozzle body 300 . A damping hole 331 that shrinks the diameter of the flow path to about φ1.0-1.5mm is provided in the middle of the cleaning flow channel 330 for women. connect. The water chamber 332 is connected to the female-only discharge channel 341 .

The cross-sectional area of the water chamber 332 is larger than the cross-sectional area of the washing channel 330 for women, and the front end side of the water chamber 332 is formed by an upwardly curved curved surface. As a result, the flow rate of the washing water flowing in from the washing water channel 330 for women decreases in the water chamber 332, and the washing water flows into the jetting channel 341 for women along the curved surface while reducing the pulsating component of the washing water. .

The base end of the female-only jet channel 341 is connected to the water chamber 332 , and the terminal end of the female-only jet channel 341 forms a female-only cleaning jet port 340 . The proximal end of the female-only discharge channel 341 is formed in a cylindrical shape with a diameter of approximately 1.8 mm, and the female-only discharge channel 341 is formed in a tapered shape (a condition that decreases over the entire circumference). In addition, the female-only discharge flow path 341 is formed so as to expand from the middle toward the terminal (the cross-sectional area thereof increases). Accordingly, the washing water flowing from the water chamber 332 into the discharge channel 341 for women can be smoothly and stably flowed in, and the washing water with less pulsating components can be sprayed from the washing discharge port 340 for women.

<4> Operation of the nozzle device and sanitary cleaning device

Next, the operation of the nozzle device 100 according to the first embodiment and the sanitation washing device 10 including the nozzle device 100 will be described with reference to FIGS. 1 to 4 .

First, as shown in FIG. 2 , the nozzle cover 400 is positioned at the rearmost portion of the nozzle guide 111 , and the nozzle body 300 is also positioned at the rearmost portion of the sliding range. This position is called a storage position, and this state is called a storage state. At this time, the discharge opening 411 of the nozzle cover 400 overlaps with the feminine washing discharge port 340 of the nozzle body 300 .

When cleaning is started from the storage state, first, the control means of the main body 20 starts to control when the user operates the remote controller 60 of the sanitary cleaning device 10 . In addition, when the sanitary washing apparatus 10 is installed in the toilet 70 and the control means of the main body 20 operates the nozzle apparatus 100 for the first time, the position control of the nozzle cover 400 is performed as follows.

That is, the control means of the main body 20 drives the drive motor 114 . In this way, the rotation of the drive motor 114 is transmitted to the pinion 115 via the plurality of transmission gears, whereby the nozzle cover 400 having the rack 421 meshing with the pinion 115 moves backward. However, since the nozzle cover 400 is located in the storage position, it cannot move further backward, and the position of the front-back direction of the nozzle cover 400 does not change. Therefore, the control means of the main body 20 stores this position as the origin, and detects the rotational speed of the drive motor 114 by the rotational speed detection sensor to estimate the movement amount of the nozzle cover 400 to control the position of the nozzle cover 400 .

Next, the control member of the main body 20 reversely rotates the driving motor 114 to move the nozzle cover 400 forward. At this time, the nozzle main body 300 is pulled by the nozzle cover 400 via the coupling member 500, and moves forward in an integrated state.

Here, when the user's operation is the operation of washing for women, the control member of the main body 20 will drive the drive motor 114 when the rotation speed of the drive motor 114 reaches the set value according to the preset control sequence (sequence). stop. Thereby, the nozzle cover 400 and the nozzle main body 300 which moved forward stop at the preset predetermined position. In addition, in this state, the feminine washing discharge port 340 is located substantially in the center of the discharge opening 411, and this position is a feminine washing position. In addition, in this state, the edge of the discharge opening 411 does not block the feminine cleansing discharge port 340 .

Next, the control means controls the cleansing water supply means to supply water to the feminine cleansing channel 330 to start feminine cleansing. The washing water jetted from the feminine washing jet port 340 is jetted out through the jet opening 411 . In addition, the switching of the washing channel and the adjustment of the flow rate are performed by the washing water supply means.

The pulsating washing water supplied by the washing water supply member flows into the women's washing flow channel 330 through the washing water supply port 339 , and flows from the women's washing flow channel 330 through the orifice 331 into the water chamber 332 . During this period, immediately after passing through the orifice 331 and flowing into the water chamber 332 , the flow rate of the washing water decreases, and the washing water generates a vortex, thereby stirring the washing water. Thereby, the pulsating feeling of the washing water can be reduced.

The washing water flowing from water chamber 332 into female-only discharge channel 341 flows in stably based on the conditions provided at the proximal end of female-only discharge channel 341 . The washing water that has flowed into the female-only discharge channel 341 flows through the female-only discharge channel 341 and is sprayed from the female-only cleaning discharge port 340 . At this time, since the female-only discharge channel 341 is formed to expand from the middle toward the terminal end, the cleaning water with less pulsating components can be sprayed from the female-only cleaning discharge port 340 , and a gentle cleaning feeling can be provided. In addition, the buttocks washing spout 320 is in a state covered by the nozzle cover main body 410, and does not directly contact sewage generated by washing for women, so it can be kept clean.

Next, when the user operates the feminine wash to stop, the control member of the main body 20 rotates the drive motor 114 in the forward direction to move the nozzle cover 400 and the nozzle main body 300 backward to return to the original storage position.

On the other hand, when the user selects buttock washing, the control member of the main body 20 rotates the driving motor 114 to move forward after confirming the origin position of the nozzle cover 400 in the same way as the feminine washing, and the nozzle The cover 400 and the nozzle body 300 move forward. Next, the control member of the main body 20 controls the drive motor 114 to move the nozzle cover 400 further forward beyond the feminine washing position.

At this time, the nozzle body 300 abuts against a front stopper (not shown) provided on the nozzle guide 111, and further forward movement of the nozzle body 300 is restricted. When the nozzle cover 400 moves further forward, the connection between the nozzle main body 300 and the nozzle cover 400 by the connection member 500 is released, and only the nozzle cover 400 moves forward. Next, the control means of the main body 20 stops the drive motor 114 when the nozzle cover 400 moves forward to the position where the discharge opening 411 overlaps with the buttock washing discharge port 320 . Moreover, in this state, the buttocks washing discharge port 320 is located in the approximate center of the discharge opening 411, and this position is a buttocks washing position.

When the nozzle cover 400 reaches the buttocks washing position, the control means controls the washing water supply means to supply water to the buttocks washing flow channel 310 through the buttocks washing water supply port 319 to start the buttocks washing. The washing water jetted from the buttock washing jet port 320 passes through the jet opening 411 and is jetted out without direct contact. In addition, the switching of the washing channel and the adjustment of the flow rate are performed by the washing water supply means. In addition, since the nozzle cover body 410 covers the upper part of the cleaning spout 340 for women, sewage generated by washing the buttocks does not directly contact the cleaning spout 340 for women. Therefore, the washing jet port 340 for women is kept clean.

Next, when the user operates to stop washing the buttocks, the control member of the main body 20 rotates the drive motor 114 in the forward direction to move the nozzle cover 400 backward. At this time, the nozzle cover 400 is connected to the nozzle main body 300 again via the connection member 500 , and the nozzle cover 400 moves backward together with the nozzle main body 300 . Next, the rear end of the nozzle body 300 abuts against a rear stopper (not shown) provided at the rear of the nozzle guide 111 , thereby restricting further backward movement of the nozzle body 300 .

When the nozzle cover 400 moves further backward, the connection with the nozzle body 300 by the connection member 500 is released, and the nozzle body 300 is separated from the nozzle cover 400 . As a result, only the nozzle cover 400 moves backward relative to the nozzle body 300 whose movement is restricted by the rear stopper to a position where the discharge opening 411 overlaps the feminine washing discharge port 340 (storage position). The control means of the main body 20 stops the drive motor 114 after the nozzle cover 400 retracts to the storage position.

<5> Function of nozzle device and sanitation cleaning device

Next, actions of the nozzle device 100 according to the first embodiment and the sanitation washing device 10 including the nozzle device 100 will be described with reference to FIGS. 6 , 7 , 8( a ) and 8 ( b ).

Fig. 8 (a) is a schematic diagram illustrating the vibration action of the buttocks discharge port of the nozzle device according to the first embodiment, and Fig. 8 (b) is a diagram illustrating the communication action of the pressure communication channel of the nozzle device according to the first embodiment. schematic diagram. In addition, in FIG. 8( a ) and FIG. 8( b ), the gap 315 and the pressure communication chamber 316 are hatched.

First, while the washing water flowing into the buttock washing flow channel 310 flows through the buttock washing flow channel 310, a swirling component is given to the speed change unit 323 (see FIGS. 6 and 7). The flow direction of the washing water to which the swirl component is given changes from the horizontal direction to the upward direction at the bent portion 311 and the bent portion 313 .

Next, as shown by the arrow A in FIG. 8( a ), the washing water flowing upward flows into the discharge channel 312 . , so a vortex is generated around the entire circumference of the stepped portion 314 . At this time, the generated vortex is not uniform, and the intensity distribution of the vortex generated in the step portion 314 occurs due to the adhesion state of the water flow to the discharge channel. As a result, pressure distribution occurs in the circumferential direction of the step portion 314 .

In the first embodiment, in particular, since the discharge flow path 312 is inclined toward the rear end side, the vortex B on the rear end side becomes stronger and the vortex B' on the front end side becomes weaker. Therefore, the pressure on the rear end side of the discharge channel 312 increases, and the pressure on the front end side decreases. Thereby, regarding the washing water flowing into the small hole portion 321, a water flow (arrow C) peeled off from the wall surface forming the small hole portion 321 is formed on the rear end side, and a water flow (arrow C) attached to the wall surface forming the small hole portion 321 is formed on the front end side ( arrow D).

At this time, since a pressure difference is generated between the rear end side and the front end side of the stepped portion 314 , the high pressure on the rear end side is transmitted to the pressure communication chamber 316 via the gap 315 . The high pressure transmitted to the pressure communication chamber 316 propagates in the pressure communication chamber 316 by the secondary water flow in the direction indicated by arrow E (refer to FIG. 8( b )). The high pressure transmitted to the tip side in the pressure communication chamber 316 is transmitted to the vortex B' on the tip side through the gap 315, and the pressure of the vortex B' increases. Then, because the pressure of the vortex B' on the front end side increases and the pressure on the vortex B' on the rear end side decreases, the water flow on the front end side in the small hole 321 is separated from the wall surface forming the small hole 321, and the water flow on the rear end side is formed. It is a flow of water attached to the wall surface forming the small hole portion 321 .

In this way, through the switch of separation and adhesion of water flow, the generation of vortex near the step portion 314 and the pressure also change. The secondary water flow in the direction indicated by F propagates to the rear end side (refer to FIG. 8( b )).

By repeating the operation of attaching and detaching alternately at the front end and the rear end in this way, the washing water becomes an oscillating water flow, widening the washing range, and is divided into a pulsating state by switching in the front and rear directions at high speed.

Next, when the washing water flows into the large hole portion 322 from the small hole portion 321, the corner portion formed by the small hole portion 321 and the large hole portion 322 is formed into a steep edge shape approximately at right angles. Vortex (see Figure 8(a)). Thereby, the pressure fluctuation of the washing water generated in the small hole portion 321 can be further amplified, and the jet stream jetted from the buttock washing jet port 320 can be given stronger pulsation. As a result, the cleaning power is improved, and the human body feels powerfully cleaned.

In this way, in the nozzle device 100 according to the first embodiment and the sanitation cleaning device 10 provided with the nozzle device 100, even if the nozzle body 300 has a plurality of discharge ports, only one discharge opening 411 is required to dissipate dirt. The parts that are easy to adhere to are minimized, so the cleanability can be improved. In addition, since the discharge port on the unused side is covered by the nozzle cover 400, the nozzle body 300 is not polluted by washing water which is dirty by washing, and hygiene can be improved. Furthermore, since the discharge opening 411 is the minimum required, the appearance is clean, and since the nozzle cover 400 also has a simple structure, cost reduction can be achieved.

In addition, in the nozzle device 100 according to the first embodiment and the sanitation cleaning device 10 including the nozzle device 100 , the nozzle body 300 and the nozzle cover 400 are linked via the coupling member 500 and the relative positions can be switched. , Therefore, it is possible to drive two driving objects to respective optimal positions with one nozzle driving member 113, and it is possible to realize miniaturization and cost reduction of the device.

In addition, in the nozzle device 100 according to the first embodiment and the sanitation washing device 10 including the nozzle device 100, the front end of the nozzle device 100 can be formed with a stepped portion 314 and a pressure communication channel 317, so that it can be easily formed. structure, miniaturization can be realized, and the cleaning water sprayed from the buttocks cleaning nozzle 320 can be formed into a strong vibrating water flow (jet flow) with a strong sense of pulsation. By repeatedly stimulating the user's skin sensation, the user can It brings about the feeling that it is powerful cleaning.

In addition, in this first embodiment, the form in which the gap 315 is provided over the entire circumference of the wall surface forming the buttock washing flow channel 310 is adopted, but it is not limited to this, as long as at least two gaps are provided in the small hole. Can.

In addition, in the first embodiment, the nozzle unit 200 is composed of two components, the nozzle body 300 and the nozzle cover 400 , but it is not limited thereto, and may be composed of only the nozzle body 300 .

In addition, in the first embodiment, the nozzle main body 300 is configured to have two functions of the buttock washing function and the feminine washing function, but it is not limited thereto, and may be configured to only have the butt washing or the feminine washing function. separate functions.

In addition, in the present first embodiment, the nozzle device 100 adopts the method of inclining the step part 314, the pressure communication channel 317, the speed change part 323, and the discharge flow channel 312, and adopting a method in which the small hole part 321 and the large hole part 322 form a step.
