Description

噴嘴裝置及具有該噴嘴裝置之衛生洗淨裝置Nozzle device and sanitary washing device having the same 發明領域Field of invention

本發明係有關於噴出用以洗淨人體之局部之洗淨水的噴嘴裝置及具有該噴嘴裝置之衛生洗淨裝置，特別是有關於一種噴嘴裝置之結構者。The present invention relates to a nozzle device for discharging a washing water for washing a part of a human body, and a sanitary washing device having the same, and more particularly to a structure of a nozzle device.

發明背景Background of the invention

習知之噴嘴裝置係於噴出口之下方設一對渦流室，並應用利用水流之壓力差，將洗淨水自激振盪之流體振盪元件，使洗淨水之噴出方向週期性地變化，藉此，擴大了洗淨範圍，並且，使強度變化(例如參照專利文獻1)。The nozzle device of the prior art is provided with a pair of vortex chambers below the discharge port, and applies a fluid oscillating element that self-oscillates the washing water by a pressure difference of the water flow, thereby periodically changing the discharge direction of the washing water. The cleaning range is expanded and the strength is changed (for example, refer to Patent Document 1).

第12圖係顯示記載於專利文獻1之液體振盪噴嘴之噴出口附近之概略結構的模式圖。Fig. 12 is a schematic view showing a schematic configuration of the vicinity of the discharge port of the liquid oscillation nozzle of Patent Document 1.

如第12圖所示，在記載於專利文獻1之液體振盪噴嘴中，於供水路徑1連接有相對於該供水路徑1約略垂直，且流路徑收縮之主噴嘴2。於主噴嘴2連通有流路徑大於主噴嘴2之主水路3。於主水路3之上游側設有導入外部空氣之空氣導入口6，且於其兩側連通有渦旋水路4。又，於主水路3之下游側連通有噴嘴出口5，噴出口5形成為開口從入口側往出口側逐漸擴大。As shown in FIG. 12, in the liquid oscillation nozzle described in Patent Document 1, the main nozzle 2 which is approximately perpendicular to the water supply path 1 and whose flow path is contracted is connected to the water supply path 1. The main nozzle 2 is connected to a main water path 3 having a flow path larger than that of the main nozzle 2. An air introduction port 6 for introducing outside air is provided on the upstream side of the main water passage 3, and a swirling water passage 4 is connected to both sides thereof. Further, a nozzle outlet 5 is communicated on the downstream side of the main water passage 3, and the discharge port 5 is formed such that the opening gradually expands from the inlet side to the outlet side.

從供水路徑1流入之洗淨水通過主噴嘴2，流入至主水路3，並從噴出口5噴出。此時，流入至主水路3之洗淨水之一部份流入至其中一渦旋水路4，藉產生渦旋流，主水路3之洗淨水之水流被牽引靠近其中一渦旋水路4側，從噴出口5噴出之洗淨水亦同樣地被牽引靠近其中一渦旋水路4側來噴出。如此一來，由於靠近之側之渦旋流路4之流速上升，且靠近之側之渦旋流路之壓力上升，而另一渦旋流路4之流速下降，故壓力下降，而產生渦旋水路4間之壓力差，主水路3之洗淨水被牽引靠近另一渦旋水路4側來噴出。然後，藉反覆進行上述動作，洗淨水可自動地振盪，振動，而從噴出口5噴出。The washing water that has flowed in from the water supply path 1 passes through the main nozzle 2, flows into the main water path 3, and is ejected from the discharge port 5. At this time, part of the washing water flowing into the main water passage 3 flows into one of the vortex water passages 4, and by the vortex flow, the water flow of the washing water of the main water passage 3 is drawn close to one of the vortex water passages 4 side. The washing water sprayed from the discharge port 5 is similarly pulled to the side of one of the swirl water passages 4 to be ejected. As a result, the flow velocity of the scroll flow path 4 on the side closer to the side rises, and the pressure of the scroll flow path on the side closer to the other side rises, and the flow velocity of the other scroll flow path 4 decreases, so that the pressure is lowered and the vortex is generated. The pressure difference between the water passages 4 and the washing water of the main water passage 3 are drawn to the side of the other scroll water passage 4 to be ejected. Then, by repeating the above operation, the washing water is automatically oscillated and vibrated, and is ejected from the discharge port 5.

又，藉從設在主水路3之空氣導入口6將外部空氣導入至主水路3內，洗淨水之量增加，並且，堵住噴出口5之作用增大。藉此，渦旋水路4間之壓力差提高，可使振盪更穩定。Further, by introducing the outside air into the main water passage 3 from the air introduction port 6 provided in the main water passage 3, the amount of the washing water increases, and the effect of blocking the discharge port 5 is increased. Thereby, the pressure difference between the vortex water paths 4 is increased, and the oscillation can be made more stable.

然而，在前述習知之結構中，由於於噴出口5之下方設用以使洗淨水振盪之2個渦旋水路4為必要之構成要件，故有噴嘴之前端部份大型化之課題。特別是在於1個噴嘴設臀部洗淨及女性洗淨等複數個噴出口之複合功能的噴嘴裝置中，除了大型化外，因構造之複雜化，有在實施上難度非常高之課題。However, in the above-described conventional configuration, since the two scroll water passages 4 for oscillating the washing water are provided below the discharge port 5, there is a problem that the front end portion of the nozzle is enlarged. In particular, in a nozzle device in which a plurality of nozzles, such as a buttock washing and a female washing, are combined in a single nozzle, in addition to the increase in size, the structure is complicated, and the difficulty in implementation is extremely high.

本發明係解決前述習知課題者，其目的係提供以小型且簡單之結構，在複合噴嘴中也易實施，並可噴出振動流之噴嘴裝置及具有該噴嘴裝置之衛生洗淨裝置。The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to provide a nozzle device which is easy to implement in a composite nozzle and which can eject a vibrating flow, and a sanitary washing device having the nozzle device, which is small and simple.

為解決前述習知之課題，本發明之噴嘴裝置係包含有噴嘴本體，並於前述噴嘴本體設有供洗淨水流淌之主水路、噴出前述洗淨水之噴出口、及連通前述主水路與前述噴出口之噴出流路，於前述噴出流路設階差部，俾使該噴出流路之截面積小於前述主水路之截面積，於前述噴出流路之外部設壓力連通路徑，前述壓力連通路徑具有設成與前述主水路連通之至少2個間隙及設成連通該至少2個間隙之連通路徑。In order to solve the above problems, the nozzle device of the present invention includes a nozzle body, and the nozzle body is provided with a main water passage for washing water flowing, a discharge port for discharging the washing water, and the main water passage and the aforementioned a discharge flow path of the discharge port, wherein the discharge flow path is provided with a step portion, the cross-sectional area of the discharge flow path is smaller than a cross-sectional area of the main water passage, and a pressure communication path is provided outside the discharge flow path, and the pressure communication path is provided There are at least two gaps that are connected to the main water passage and a communication path that is connected to the at least two gaps.

藉此，從主水路流入至噴出流路之洗淨水在階差部產生旋渦。因此，在噴出流路之入口附近，洗淨水之一部份從形成噴出流路之壁面剝離，而形成為壓力上升之水流，又，一部份附著於形成噴出流路之壁面，而形成為壓力降低之水流。因產生壓力差，從壓力高之剝離側朝壓力低之附著側，藉由壓力連通路徑，產生二次流。藉此二次流之作用，附著之水流移至已剝離之水流，附著側之壓力上升，藉此，產生相反之之壓力差。因壓力差反轉，產生反向之二次流，剝離側之壓力再度上升。藉反覆進行該等作用，附著處與剝離處之移動交互產生，而可使流入至噴出流路之洗淨水振盪(可使洗淨水形成為振動流)。Thereby, the washing water flowing from the main water passage to the discharge flow path generates a vortex at the step portion. Therefore, in the vicinity of the inlet of the discharge flow path, a part of the washing water is peeled off from the wall surface forming the discharge flow path, and is formed into a water flow in which the pressure rises, and a part is attached to the wall surface forming the discharge flow path, and is formed. A stream of water that is reduced in pressure. Due to the pressure difference, a secondary flow is generated by the pressure communication path from the peeling side where the pressure is high to the side where the pressure is low. By this secondary flow, the adhered water flow moves to the stripped water stream, and the pressure on the attachment side rises, thereby generating an opposite pressure difference. Since the pressure difference is reversed, a reverse secondary flow is generated, and the pressure on the peeling side rises again. By repeating these effects, the movement of the attachment portion and the peeling portion alternates, and the washing water flowing into the discharge flow path can be oscillated (the washing water can be formed into a vibration flow).

又，由於噴出流路因階差部，其截面積小，故可增大上述振動流之脈動。因此，可使從噴出口噴出之洗淨水為脈動感強之振動流(噴流)，而反覆進行對使用者之皮膚感覺之刺激，可使使用者產生強勁之洗淨之感覺。Further, since the discharge flow path has a small cross-sectional area due to the step portion, the pulsation of the above-described vibration flow can be increased. Therefore, the washing water sprayed from the discharge port can be a pulsating vibration flow (jet flow), and the skin feeling of the user can be repeatedly stimulated, and the user can feel a strong washing feeling.

因而，在本發明之噴嘴裝置中，可使從噴出口噴出之洗淨水為帶有振動流之噴流，而可提高洗淨力，並且，可提高洗淨感。又，在本發明之噴嘴裝置中，由於可在階差部及壓力連通路徑實施上述脈動感強之振動流，故可形成為簡單之結構，而可將噴嘴裝置小型化。Therefore, in the nozzle device of the present invention, the washing water sprayed from the discharge port can be a jet flow having a vibrating flow, and the washing power can be improved, and the washing feeling can be improved. Further, in the nozzle device of the present invention, since the vibration flow having the strong pulsation feeling can be performed in the step portion and the pressure communication path, the nozzle device can be formed into a simple structure and the nozzle device can be downsized.

又，本發明之衛生洗淨裝置包含有上述本發明之噴嘴裝置、將洗淨水供給至噴嘴裝置之洗淨水供給機構、控制噴嘴裝置及洗淨水供給機構之控制機構、及載置於便器之上面之便座。Further, the sanitary washing device of the present invention includes the nozzle device of the present invention, a washing water supply mechanism for supplying washing water to the nozzle device, a control mechanism for controlling the nozzle device and the washing water supply mechanism, and a loading mechanism. The toilet seat above the toilet.

藉此，可提供洗淨力高，且洗淨感高之衛生洗淨裝置。Thereby, it is possible to provide a sanitary washing device which has high detergency and high washing feeling.

本發明之上述目的、其他目的、特徵及優點在參照附加圖式下，可從以下之較佳實施形態之詳細說明明瞭。The above and other objects, features and advantages of the present invention will become apparent from

根據本發明之噴嘴裝置及具有該噴嘴裝置之衛生洗淨裝置，可以小型且簡單之結構使洗淨力及洗淨感高之振動流產生。According to the nozzle device of the present invention and the sanitary washing device having the same, it is possible to generate a vibration flow having a high washing power and a high washing feeling in a small and simple configuration.

用以實施發明之形態Form for implementing the invention

本發明之噴嘴裝置包含有噴嘴本體，並於噴嘴本體設有供洗淨水流淌之主水路、噴出洗淨水之噴出口、及連通主水路與噴出口之噴出流路，於噴出流路設階差部，俾使該噴出流路之截面積小於前述主水路之截面積，於噴出流路之外部設壓力連通路徑，壓力連通路徑具有設成與主水路連通之至少2個間隙及設成連通該至少2個間隙之連通路徑。The nozzle device of the present invention includes a nozzle body, and a nozzle main body is provided with a main water passage for washing water flowing, a discharge port for discharging the washing water, and a discharge flow path for connecting the main water passage and the discharge port, and is disposed in the discharge flow path. The step portion is configured such that a cross-sectional area of the discharge flow path is smaller than a cross-sectional area of the main water passage, and a pressure communication path is provided outside the discharge flow path, and the pressure communication path has at least two gaps connected to the main water passage and is configured A communication path connecting the at least two gaps.

在此，噴出流路之截面積係指相對於噴出流路內之洗淨水之流淌方向垂直之方向的截面積。同樣地，主水路之截面積係指相對於主水路內之洗淨水之流淌方向垂直之方向的截面積。Here, the cross-sectional area of the discharge flow path means a cross-sectional area in a direction perpendicular to the flow direction of the washing water in the discharge flow path. Similarly, the cross-sectional area of the main water passage refers to the cross-sectional area in the direction perpendicular to the flow direction of the washing water in the main water passage.

又，連通路徑與主水路不同，形成為連通至少2個間隙。Further, the communication path is different from the main water path and is formed to communicate with at least two gaps.

藉此，從主水路流入至噴出流路之洗淨水在階差部產生旋渦。因此，在噴出流路之入口附近，洗淨水之一部份從形成噴出流路之壁面剝離，而形成為壓力上升之水流，又，洗淨水之另一部份附著於形成噴出流路之壁面，而形成為壓力降低之水流。因產生壓力差，從壓力高之剝離側朝壓力低之附著側，藉由壓力連通路徑，產生二次流。藉此二次流之作用，附著之水流移至已剝離之水流，附著側之壓力上升，藉此，產生相反之之壓力差。因壓力差反轉，產生反向之二次流，剝離側之壓力再度上升。藉反覆進行該等作用，附著處與剝離處之移動交互產生，而可使流入至噴出流路之洗淨水振盪(可使洗淨水形成為振動流)。Thereby, the washing water flowing from the main water passage to the discharge flow path generates a vortex at the step portion. Therefore, in the vicinity of the inlet of the discharge flow path, one part of the washing water is peeled off from the wall surface forming the discharge flow path, and is formed as a water flow in which the pressure rises, and another part of the washing water adheres to the formation of the discharge flow path. The wall is formed as a water flow with reduced pressure. Due to the pressure difference, a secondary flow is generated by the pressure communication path from the peeling side where the pressure is high to the side where the pressure is low. By this secondary flow, the adhered water flow moves to the stripped water stream, and the pressure on the attachment side rises, thereby generating an opposite pressure difference. Since the pressure difference is reversed, a reverse secondary flow is generated, and the pressure on the peeling side rises again. By repeating these effects, the movement of the attachment portion and the peeling portion alternates, and the washing water flowing into the discharge flow path can be oscillated (the washing water can be formed into a vibration flow).

又，由於噴出流路因階差部，其截面積小，故可增大上述振動流之振幅。因此，可使從噴出口噴出之洗淨水為脈動感強之振動流(噴流)，而藉反覆進行對使用者之皮膚感覺之刺激，可使使用者產生強勁之洗淨之感覺。Further, since the discharge flow path has a small cross-sectional area due to the step portion, the amplitude of the vibration flow can be increased. Therefore, the washing water sprayed from the discharge port can be a pulsating vibration flow (jet flow), and the user can feel a strong feeling of washing by repeatedly stimulating the skin feeling of the user.

又，在本發明之噴嘴裝置中，壓力連通路徑設成沿著噴出流路之外周。Further, in the nozzle device of the present invention, the pressure communication path is provided along the outer circumference of the discharge flow path.

藉此，可將壓力連通路徑對應於在階差部全區所產生之壓力差，而可使振動流確實地產生，並且，可以簡單之結構實施壓力連通路徑。Thereby, the pressure communication path can be made to correspond to the pressure difference generated in the entire section of the step portion, and the vibration flow can be surely generated, and the pressure communication path can be implemented in a simple structure.

又，在本發明之噴嘴裝置中，壓力連通路徑亦可以設成沿著噴出流路之外周之間隙與連通於該間隙之末端之環狀壓力連通室構成。Further, in the nozzle device of the present invention, the pressure communication path may be formed along the gap between the outer circumference of the discharge flow path and the annular pressure communication chamber that communicates with the end of the gap.

藉此，可將壓力連通路徑對應於在階差部全區所產生之壓力差，而可使振動流確實地產生，並且，可以簡單之結構實施壓力連通路徑。Thereby, the pressure communication path can be made to correspond to the pressure difference generated in the entire section of the step portion, and the vibration flow can be surely generated, and the pressure communication path can be implemented in a simple structure.

又，在本發明之噴嘴裝置中，噴出流路亦可形成段狀為前端部之截面積大於基端部。Further, in the nozzle device of the present invention, the discharge flow path may be formed in a segment shape such that the front end portion has a larger cross-sectional area than the base end portion.

藉此，已形成為振動流之洗淨水在噴出流路流淌時，在噴出流路之形成段狀之部份(角)產生旋渦，藉此，在噴出流路內產生壓力差，而可使洗淨水之脈動更增大振幅，而可使脈動感更增大。Thereby, when the washing water which has been formed as the vibrating flow flows in the discharge flow path, a vortex is generated in a portion (angle) where the discharge flow path is formed, whereby a pressure difference is generated in the discharge flow path, and The pulsation of the washing water is increased to increase the amplitude, and the pulsation feeling is further increased.

又，在本發明之噴嘴裝置中，噴出流路亦可設成其軸心相對於前述主水路之軸心於前述噴嘴本體之後端側傾斜5~20度。Further, in the nozzle device of the present invention, the discharge flow path may be formed such that its axis is inclined by 5 to 20 degrees with respect to the axial center of the nozzle main body toward the rear end side of the nozzle body.

藉此，在噴出流路內，洗淨水更易產生適度之剝離及附著，而可使振動流更穩定地產生，且可使洗淨水之振動振幅更增大。Thereby, in the discharge flow path, the washing water is more likely to cause appropriate peeling and adhesion, and the vibration flow can be more stably generated, and the vibration amplitude of the washing water can be further increased.

又，在本發明之噴嘴裝置中，包含有覆蓋噴嘴之至少一部份之筒狀噴嘴蓋，於噴嘴蓋設噴出開口，噴嘴本體與噴嘴蓋構造成可滑動。Further, the nozzle device of the present invention includes a cylindrical nozzle cover that covers at least a portion of the nozzle, and the nozzle opening is provided with a discharge opening, and the nozzle body and the nozzle cover are configured to be slidable.

藉此，於噴出洗淨水時，噴嘴本體、特別是噴出口之附近以噴嘴蓋覆蓋，以因洗淨而髒污之洗淨水污染噴嘴本體之情形少而衛生。Thereby, when the washing water is sprayed, the nozzle body, in particular, the vicinity of the discharge port is covered with the nozzle cover, and the washing water contaminated by the washing contaminates the nozzle body to be small and sanitary.

又，在本發明之噴嘴裝置中，於主水路之途中設有構造成變更在該主水路流淌之洗淨水之一部份之流速的變速部。Moreover, in the nozzle device of the present invention, a shifting portion configured to change the flow velocity of a portion of the washing water flowing in the main water passage is provided in the middle of the main water passage.

藉此，由於在主水路流淌之洗淨水在變速部破壞流速之平衡，故賦與渦旋成份。因此，經賦與渦旋成份之洗淨水流入至噴出流路。然後，流入至噴出流路內之洗淨水流動成其一部份從形成噴出流路之壁面剝離，且流動成另一部份附著於壁面。此時，由於洗淨水經賦與了渦旋成份，故剝離處與附著處依序移動，而更易產生振動流。Thereby, since the washing water flowing in the main water passage breaks the balance of the flow velocity at the shifting portion, the swirl component is imparted. Therefore, the washing water to which the vortex component is imparted flows into the discharge flow path. Then, the washing water flowing into the discharge flow path flows so that a part thereof is peeled off from the wall surface forming the discharge flow path, and flows into another portion to adhere to the wall surface. At this time, since the washing water is imparted with the vortex component, the peeling portion and the adhering portion are sequentially moved, and the vibrating flow is more likely to occur.

再者，在本發明之噴嘴裝置中，於主水路之途中設有彎折成直角狀之彎折部及具有彎曲面之彎曲部，變速部以彎折部及彎曲部構成。Further, in the nozzle device of the present invention, a bent portion bent in a right angle and a bent portion having a curved surface are provided in the middle of the main water passage, and the shifting portion is formed by a bent portion and a bent portion.

藉此，在變速部中，可更易對洗淨水賦與渦旋成份。Thereby, in the shifting portion, it is easier to impart a swirl component to the washing water.

又，本發明之衛生洗淨裝置包含有上述噴嘴裝置、將洗淨水供給至噴嘴裝置之洗淨水供給機構、控制噴嘴裝置及洗淨水供給機構之控制機構、及載置於便器之上面之便座。Moreover, the sanitary washing apparatus of the present invention includes the nozzle device, a washing water supply mechanism that supplies washing water to the nozzle device, a control mechanism that controls the nozzle device and the washing water supply mechanism, and a load on the toilet.

藉此，在變速部323，在臀部洗淨流路310流淌之洗淨水在設有彎折部311之其中一側及設有彎曲部313之另一側，流速改變，而可對洗淨水賦與渦旋成份。As a result, in the shifting portion 323, the washing water flowing through the buttocks washing flow path 310 is provided on one side of the bent portion 311 and the other side of the curved portion 313, and the flow rate is changed, and the washing water can be washed. Water and vortex components.

此外，在第1實施形態中，採用了變速部323以彎折部311及彎曲部313構成之形態，但不限於此。變速部323只要可將在臀部洗淨流路310流淌之洗淨水之一部份的流速相對於另一洗淨水之流速改變，不論為何種形態皆可。舉例言之，亦可採用變速部323以彎曲部313構成之形態。Further, in the first embodiment, the shifting portion 323 is configured by the bent portion 311 and the curved portion 313, but the invention is not limited thereto. The shifting portion 323 may change the flow rate of one portion of the washing water flowing through the buttocks washing passage 310 with respect to the flow rate of the other washing water, regardless of the form. For example, the shifting portion 323 may be configured in the form of a curved portion 313.

又，在本第1實施形態中，採用了將彎折部311及彎曲部313設於臀部洗淨流路310之相同之位置(在洗淨水之流淌方向，相同之位置)的形態，但不限於此。亦可採用彎折部311及彎曲部313設在臀部洗淨流路310之不同之位置(在洗淨水之流淌方向，不同之位置)之形態。即，彎曲部313可設於彎折部311之上游側，亦可設於彎折部311之下游側。此時，彎曲部313可彎曲成凸狀，亦可彎曲成凹狀。Further, in the first embodiment, the bent portion 311 and the curved portion 313 are provided at the same position (the same position in the flow direction of the washing water) as the buttock washing flow path 310, but Not limited to this. The bent portion 311 and the curved portion 313 may be provided at different positions of the buttocks washing flow path 310 (in the flow direction of the washing water, at different positions). That is, the curved portion 313 may be provided on the upstream side of the bent portion 311 or on the downstream side of the bent portion 311. At this time, the curved portion 313 may be curved in a convex shape or may be curved in a concave shape.

又，如第6圖及第7圖所示，噴出流路312形成段狀成前端部322之流淌截面積大於基端部321。基端部(以下稱為小孔部)321形成直徑約1.5~1.7mm之圓柱狀，前端部(以下稱為大孔部)322形成直徑約1.9~2.1mm之圓柱狀。此外，在此，採用了噴出流路312以小孔部321及大孔部322之2段構成之形狀，但不限於此。噴出流路312只要形成段狀成前端部322之流淌截面積大於基端部321即可，亦可採用以複數段(例如小孔部、中孔部及大孔部)構成之形態。Further, as shown in FIGS. 6 and 7, the discharge flow path 312 is formed in a segment shape so that the flow end portion of the front end portion 322 is larger than the base end portion 321. The base end portion (hereinafter referred to as a small hole portion) 321 is formed in a columnar shape having a diameter of about 1.5 to 1.7 mm, and the tip end portion (hereinafter referred to as a large hole portion) 322 is formed in a cylindrical shape having a diameter of about 1.9 to 2.1 mm. Here, the shape in which the discharge flow path 312 is formed by the two holes of the small hole portion 321 and the large hole portion 322 is adopted, but the shape is not limited thereto. The discharge flow path 312 may be formed in a plurality of stages (for example, a small hole portion, a middle hole portion, and a large hole portion) as long as the flow rate of the end portion 322 is larger than the base end portion 321 .

噴出流路312設成其軸心相對於臀部洗淨流路310之軸心，於噴嘴本體300之後端側傾斜約7度。從使從臀部洗淨噴出口320噴出之洗淨水為脈動感強之振動流(噴流)之觀點，噴出流路312之軸心宜相對於臀部洗淨流路310之軸心，於噴嘴本體300之後端側傾斜5度以上。又，從將從臀部洗淨噴出口320噴出之洗淨水接觸使用者之局部的觀點，噴出流路312之軸心宜相對於臀部洗淨流路310之軸心，於噴嘴本體300之後端側傾斜20度以下。The discharge flow path 312 is disposed such that its axial center is inclined with respect to the axial center of the buttocks washing flow path 310, and is inclined by about 7 degrees on the rear end side of the nozzle body 300. The washing water sprayed from the buttock washing discharge port 320 is a pulsating vibration flow (jet flow), and the axial center of the discharge flow path 312 is preferably opposite to the axial center of the buttock washing flow path 310. After 300, the end side is inclined by more than 5 degrees. Moreover, from the viewpoint of contacting the washing water sprayed from the buttocks washing discharge port 320 to the user, the axial center of the discharge flow path 312 is preferably at the rear end of the nozzle body 300 with respect to the axial center of the buttock washing flow path 310. The side is inclined at 20 degrees or less.

藉此，洗淨水在小孔部321之後端側之壁面易剝離，並且，在前端側易附著。因此，可破壞水流之平衡，而可更易產生振動流。Thereby, the wall surface of the end side of the small hole portion 321 of the washing water is easily peeled off, and the front end side is easily attached. Therefore, the balance of the water flow can be broken, and the vibration flow can be more easily generated.

又，以噴出流路312之小孔部321及大孔部322形成之角之部份以峭立成約直角之稜狀形成。藉此，在以噴出流路312之小孔部321及大孔部322形成之角之部份產生旋渦，而易產生水流之剝離。即，從小孔部321噴出至大孔部322之洗淨水之一部份附著於大孔部322之側壁，洗淨水之另一部份從大孔部322之側壁剝離，產生壓力差，而可引起壓力變動。因此，可使在大孔部322流淌之洗淨水之振動的振幅增大。Further, a portion of the corner formed by the small hole portion 321 and the large hole portion 322 of the discharge flow path 312 is formed in a rib shape which is formed at a right angle. Thereby, a vortex is generated in a portion where the small hole portion 321 and the large hole portion 322 of the discharge flow path 312 are formed, and peeling of the water flow is liable to occur. That is, a part of the washing water sprayed from the small hole portion 321 to the large hole portion 322 is attached to the side wall of the large hole portion 322, and another portion of the washing water is peeled off from the side wall of the large hole portion 322, causing a pressure difference. , can cause pressure changes. Therefore, the amplitude of the vibration of the washing water flowing in the large hole portion 322 can be increased.

又，於臀部洗淨流路310與噴出流路312之小孔部321之連接部份形成有階差部314。即，由於小孔部321之直徑較臀部洗淨流路310之直徑小，故於臀部洗淨流路310與小孔部321之連接部份形成階差，該部份構成階差部314。Further, a step portion 314 is formed at a portion where the buttocks cleaning flow path 310 and the small hole portion 321 of the discharge flow path 312 are connected. In other words, since the diameter of the small hole portion 321 is smaller than the diameter of the buttocks washing flow path 310, a step is formed at the portion where the buttocks washing flow path 310 and the small hole portion 321 are connected, and this portion constitutes the step portion 314.

於階差部314之外部設有壓力連通路徑317。壓力連通路徑317以噴嘴本體基材301與噴嘴蓋構件302之間隙形成，而形成為包圍噴出流路312。在本第1實施形態中，壓力連通路徑317以間隙315及壓力連通室316構成。A pressure communication path 317 is provided outside the step portion 314. The pressure communication path 317 is formed by a gap between the nozzle body substrate 301 and the nozzle cover member 302, and is formed to surround the discharge flow path 312. In the first embodiment, the pressure communication path 317 is constituted by a gap 315 and a pressure communication chamber 316.

間隙315形成為其基端(上游端)與臀部洗淨流路310連通，並沿著噴出流路312之外周，形成環狀。即，在本第1實施形態中，間隙312兼作設成與臀部洗淨流路310連通之至少2個相對之間隙及設成連通該至少2個相對之間隙之連通路徑。又，壓力連通室316與間隙315之末端(下游端)連通，形成環狀。此外，在本第1實施形態中，壓力連通室316構造成其體積大於間隙315。The gap 315 is formed such that its base end (upstream end) communicates with the buttocks washing flow path 310, and forms an annular shape along the outer circumference of the discharge flow path 312. In other words, in the first embodiment, the gap 312 also serves as a communication path that communicates with at least two of the gaps that communicate with the buttocks washing flow path 310 and that communicates with the at least two opposing gaps. Further, the pressure communication chamber 316 communicates with the end (downstream end) of the gap 315 to form a ring shape. Further, in the first embodiment, the pressure communication chamber 316 is configured to have a larger volume than the gap 315.

藉此，從臀部洗淨流路310施加至階差部314之特定處之高壓力藉由壓力連通路徑317，傳送至與階差部314之前述特定處不同之處(在此為相對之處)，而可提高該部份之壓力。此外，如後述，壓力連通路徑317只要具有設成與臀部洗淨流路310連通之至少2個間隙及設成連通該至少2個間隙之連通路徑即可，可採用各種形態。Thereby, the high pressure applied from the buttocks washing flow path 310 to the specific portion of the step portion 314 is transmitted to the specific portion of the step portion 314 by the pressure communication path 317 (in this case, the opposite is the opposite) ), which can increase the pressure on this part. Further, as will be described later, the pressure communication path 317 may have at least two gaps that communicate with the buttocks washing flow path 310 and a communication path that communicates with the at least two gaps.

如第6圖所示，女性洗淨流路330從噴嘴本體300之後端部至前端部附近，以約3.0~3.5mm之流路徑與噴嘴本體300之軸心約平行地配設。於女性洗淨流路330之途中設有將流路徑收縮至ψ1.0~1.5mm左右之孔口331，其前端部連接於配設於女性洗淨噴出口340下方之水室332。於水室332連接有女性噴出流路341。As shown in Fig. 6, the female washing flow path 330 is disposed approximately parallel to the axis of the nozzle body 300 from the rear end portion of the nozzle body 300 to the vicinity of the front end portion with a flow path of about 3.0 to 3.5 mm. In the middle of the female washing channel 330, an orifice 331 for contracting the flow path to about 1.0 to 1.5 mm is provided, and the front end portion is connected to a water chamber 332 disposed below the female washing and discharging port 340. A female discharge flow path 341 is connected to the water chamber 332.

水室332具有大於女性洗淨流路330之截面積，其前端側以彎曲至上方之彎曲面形成。藉此，從女性洗淨流路330流入之洗淨水在水室332內減低流速，而在使洗淨水具有之脈動成份減低之狀態下，沿著彎曲面流入至女性噴出流路341。The water chamber 332 has a cross-sectional area larger than that of the female washing flow path 330, and its front end side is formed by a curved surface that is curved upward. In this way, the washing water that has flowed in from the female washing channel 330 is reduced in the flow rate in the water chamber 332, and flows into the female discharge channel 341 along the curved surface while the pulsating component of the washing water is reduced.

女性噴出流路341之基端連接於水室332，其末端形成女性洗淨噴出口340。女性噴出流路341之基端形成直徑約1.8mm之圓筒狀，而形成錐狀(橫亙全周形成小之曲面)。又，女性噴出流路341形成為從其途中朝末端擴大(其截面積增大)。藉此，可使從水室332流入至女性噴出流路341之洗淨水平順地穩定流入，並且，可從女性洗淨噴出口340噴出脈動成份少之洗淨水。The base end of the female discharge flow path 341 is connected to the water chamber 332, and the female washing discharge port 340 is formed at the end. The base end of the female discharge flow path 341 is formed into a cylindrical shape having a diameter of about 1.8 mm, and is formed into a tapered shape (a small curved surface is formed over the entire circumference). Further, the female discharge flow path 341 is formed to expand toward the end from the middle thereof (the cross-sectional area thereof is increased). As a result, the level of washing from the water chamber 332 to the female discharge channel 341 can be stably flowed in, and the washing water having a small pulsation component can be ejected from the female washing port 340.

<4>噴嘴裝置及衛生洗淨裝置之動作<4> Action of nozzle device and sanitary washing device

接著，就本第1實施形態之噴嘴裝置100及具有其之衛生洗淨裝置10之動作，一面參照第1圖至第4圖，一面說明。Next, the operation of the nozzle device 100 and the sanitary washing device 10 according to the first embodiment will be described with reference to Figs. 1 to 4 .

首先，如第2圖所示，噴嘴蓋400位於噴嘴導件111之最後部，噴嘴本體300亦位於滑動範圍之最後部。將此位置稱為收納位置，將此狀態稱為收納狀態。此時，噴嘴蓋400之噴出開口411形成為與噴嘴本體300之女性洗淨噴出口340重疊之狀態。First, as shown in Fig. 2, the nozzle cover 400 is located at the rear of the nozzle guide 111, and the nozzle body 300 is also located at the rear of the sliding range. This position is referred to as a storage position, and this state is referred to as a storage state. At this time, the discharge opening 411 of the nozzle cover 400 is formed in a state of being overlapped with the female washing discharge port 340 of the nozzle body 300.

於從收納狀態開始洗淨之際，首先，藉使用者操作衛生洗淨裝置10之遠程控制器60，本體20之控制機構開始控制。此外，將衛生洗淨裝置10設置於便器70，本體20之控制機構最先使噴嘴裝置100作動時，如以下進行，來進行噴嘴蓋400之位置控制。When the washing is started from the storage state, first, by the user operating the remote controller 60 of the sanitary washing device 10, the control mechanism of the main body 20 starts control. Further, when the sanitary washing device 10 is installed in the toilet 70, and the control mechanism of the main body 20 first operates the nozzle device 100, the position control of the nozzle cover 400 is performed as follows.

即，本體20之控制機構使驅動馬達114驅動。如此一來，藉驅動馬達114之旋轉藉由複數個變速齒輪，傳至小齒輪115，而使具有與小齒輪115咬合之架421之噴嘴蓋400移動至後方。然而，由於噴嘴蓋400位於收納位置，故無法再進一步移動至後方，噴嘴蓋400之前後方向之位置不變化。是故，本體20之控制機構將此位置記憶為原點，以轉速探測感測器探測驅動馬達114之轉速，推定噴嘴蓋400之移動量，藉此，進行噴嘴蓋400之位置控制。That is, the control mechanism of the body 20 drives the drive motor 114. As a result, the rotation of the drive motor 114 is transmitted to the pinion gear 115 by a plurality of shift gears, and the nozzle cover 400 having the frame 421 engaged with the pinion gear 115 is moved to the rear. However, since the nozzle cover 400 is located at the storage position, it is no longer possible to move further to the rear, and the position of the nozzle cover 400 in the front-rear direction does not change. Therefore, the control mechanism of the body 20 memorizes the position as the origin, and the rotation detecting sensor detects the rotation speed of the driving motor 114, and estimates the movement amount of the nozzle cover 400, whereby the position control of the nozzle cover 400 is performed.

接著，本體20之控制機構使驅動馬達114反向旋轉，而使噴嘴蓋400移動至前方。此時，噴嘴本體300為連結機構500牽引至噴嘴蓋400，而以一體化之狀態移動至前方。Next, the control mechanism of the body 20 causes the drive motor 114 to rotate in the reverse direction, and the nozzle cover 400 is moved to the front. At this time, the nozzle body 300 is pulled to the nozzle cover 400 by the coupling mechanism 500, and is moved to the front in an integrated state.

在此，當使用者之操作為女性洗淨之操作時，本體20之控制機構根據預先設定之控制程序，當驅動馬達114之轉速到達設定值時，便使驅動馬達114停止。藉此，移動至前方之噴嘴蓋400及噴嘴本體300在預先設定之預定位置停止。此外，在此狀態下，女性洗淨噴出口340位於噴出開口411之約中央，此位置形成為女性洗淨位置。又，在此狀態下，噴出開口411之緣部不致遮蓋女性洗淨噴出口340。Here, when the operation of the user is a female washing operation, the control unit of the main body 20 stops the driving motor 114 when the rotational speed of the driving motor 114 reaches the set value according to a preset control program. Thereby, the nozzle cover 400 and the nozzle body 300 that have moved to the front are stopped at predetermined positions set in advance. Further, in this state, the female washing discharge port 340 is located at the center of the discharge opening 411, and this position is formed as a female washing position. Further, in this state, the edge portion of the discharge opening 411 does not cover the female washing discharge port 340.

接著，控制機構控制洗淨水供給機構，藉排水至女性洗淨流路330，而開始女性洗淨。從女性洗淨噴出口340噴出之洗淨水通過噴出開口411來噴射。此外，洗淨流路之切換及流量之調節以洗淨水供給機構進行。Next, the control unit controls the washing water supply mechanism to start the female washing by draining the water to the female washing flow path 330. The washing water sprayed from the female washing nozzle 340 is sprayed through the discharge opening 411. Further, the switching of the washing flow path and the adjustment of the flow rate are performed by the washing water supply mechanism.

從洗淨水供給機構供給之帶有脈動之洗淨水藉由洗淨水供給口339，流入至女性洗淨流路330，從女性洗淨流路330通過孔口331，流入至水室332。在此期間，通過孔口331後及流入至水室332後，洗淨水之流速即刻減緩，同時，洗淨水產生渦流而被攪拌。藉此，可使洗淨水之脈動感減低。The pulsating washing water supplied from the washing water supply means flows into the female washing flow path 330 through the washing water supply port 339, passes through the orifice 331 from the female washing flow path 330, and flows into the water chamber 332. . During this period, after passing through the orifice 331 and flowing into the water chamber 332, the flow rate of the washing water is immediately slowed down, and at the same time, the washing water is vortexed and stirred. Thereby, the pulsation of the washing water can be reduced.

從水室332流入至女性噴出流路341之洗淨水藉設於女性噴出流路341之基端部之曲面，穩定地流入。流入至女性噴出流路341之洗淨水在該女性噴出流路341流淌，而從女性洗淨噴出口340噴出。此時，由於女性噴出流路341形成為從其途中朝末端擴大，故可從女性洗淨噴出口340噴出脈動成份少之洗淨水，而可提供輕柔之洗淨感。此外，由於臀部洗淨噴出口320為以噴嘴蓋本體410覆蓋之狀態，不致直接濺到因女性洗淨而產生之污水，故可保持清潔。The washing water that has flowed into the female discharge channel 341 from the water chamber 332 is stably introduced by the curved surface of the base end portion of the female discharge channel 341. The washing water that has flowed into the female discharge passage 341 flows through the female discharge passage 341 and is discharged from the female washing discharge port 340. At this time, since the female discharge flow path 341 is formed to expand toward the distal end from the middle, the washing water having a small pulsation component can be ejected from the female washing discharge port 340, and a gentle washing feeling can be provided. Further, since the buttock washing and discharging port 320 is covered by the nozzle cap body 410, the sewage generated by the female washing is not directly splashed, so that it can be kept clean.

然後，當使用者操作女性洗淨之停止時，本體20之控制機構使驅動馬達114正向旋轉，而使噴嘴蓋400及噴嘴本體300移動至後方，而回復至原本之收納位置。Then, when the user stops the female washing, the control mechanism of the main body 20 causes the driving motor 114 to rotate forward, and the nozzle cover 400 and the nozzle body 300 are moved to the rear to return to the original storage position.

另一方面，當使用者選擇臀部洗淨時，本體20之控制機構與女性洗淨同樣地，確認噴嘴蓋400之原點位置後，為移動至前方，而使驅動馬達114旋轉，而使噴嘴蓋400與噴嘴本體300移動至前方。然後，本體20之控制機構控制馬達114，俾越過女性洗淨位置，使噴嘴蓋400進一步移動至前方。On the other hand, when the user selects the buttocks to be washed, the control means of the main body 20 confirms the origin position of the nozzle cover 400, and then moves to the front, and the drive motor 114 is rotated to make the nozzle The cover 400 and the nozzle body 300 are moved to the front. Then, the control mechanism of the body 20 controls the motor 114 to pass the female washing position to further move the nozzle cover 400 to the front.

此時，噴嘴本體300抵接設於噴嘴導件111之前制動器(圖中未示)，噴嘴本體300被限制無法再往前移動。當噴嘴蓋400再移動至前方時，噴嘴本體300及噴嘴蓋400之以連結機構500所作之連結脫離，而僅噴嘴蓋400移動至前方。然後，本體20之控制機構當噴嘴蓋400移動至前方至噴出開口411與臀部洗淨噴出口320重疊之位置為止時，便使驅動馬達114停止。此外，在此狀態下，臀部洗淨噴出口320位於噴出開口411之約中央，此位置形成為臀部洗淨位置。At this time, the nozzle body 300 abuts against the brake (not shown) provided before the nozzle guide 111, and the nozzle body 300 is restricted from moving further forward. When the nozzle cover 400 is moved further to the front, the nozzle body 300 and the nozzle cover 400 are disconnected by the coupling mechanism 500, and only the nozzle cover 400 is moved to the front. Then, the control mechanism of the main body 20 stops the drive motor 114 when the nozzle cover 400 moves to the front until the discharge opening 411 overlaps the buttock washing discharge port 320. Further, in this state, the buttock washing discharge port 320 is located at the center of the discharge opening 411, and this position is formed as a buttock washing position.

在噴嘴蓋400到達上述臀部洗淨位置之時間點，控制機構控制洗淨水供給機構，藉藉由臀部洗淨水供給口319，排水至臀部洗淨流路310，而開始臀部洗淨。從臀部洗淨噴出口320噴出之洗淨水在不直接接觸噴出開口411下通過而噴射。此外，洗淨流路之切換及流量之調節以洗淨水供給機構進行。又，由於女性洗淨噴出口340之上方以噴嘴蓋本體410覆蓋，故因臀部洗淨而產生之污水不致直接濺至女性洗淨噴出口340。因此，女性洗淨噴出口340可保持清潔。When the nozzle cover 400 reaches the above-described buttock washing position, the control means controls the washing water supply means to drain the buttocks washing flow path 310 by the buttocks washing water supply port 319, and starts the buttock washing. The washing water sprayed from the buttock washing discharge port 320 is sprayed without being directly contacted by the discharge opening 411. Further, the switching of the washing flow path and the adjustment of the flow rate are performed by the washing water supply mechanism. Further, since the upper portion of the female washing spout 340 is covered by the nozzle cap body 410, the sewage generated by the washing of the buttocks is not directly splashed on the female washing spout 340. Therefore, the female washing spout 340 can be kept clean.

然後，當使用者操作臀部洗淨之停止時，本體20之控制機構使驅動馬達正向旋轉，而使噴嘴蓋400移動至後方。此時，噴嘴蓋400以連結機構500再度與噴嘴本體300連結，噴嘴蓋400與噴嘴本體300一同移動至後方。然後，藉噴嘴本體300之後端抵接設於噴嘴導件111後部之後制動器(圖中未示)，噴嘴本體300被限制不再往後移動。Then, when the user operates the stop of the buttock washing, the control mechanism of the body 20 causes the drive motor to rotate in the forward direction, and the nozzle cover 400 is moved to the rear. At this time, the nozzle cover 400 is again coupled to the nozzle body 300 by the coupling mechanism 500, and the nozzle cover 400 moves to the rear together with the nozzle body 300. Then, after the rear end of the nozzle body 300 abuts against a stopper (not shown) provided at the rear of the nozzle guide 111, the nozzle body 300 is restricted from moving backward.

當噴嘴蓋400再移動至後方時，連結機構500所作之與噴嘴本體300之連結脫離，噴嘴本體300與噴嘴蓋400形成為分離之狀態。藉此，相對於以後制動器限制移動之噴嘴本體300，僅噴嘴蓋400移動至後方至噴出開口411與女性洗淨噴出口340重疊之位置(收納位置)為止。當本體20之控制機構當噴嘴蓋400後退至收納位置時，便使驅動馬達114停止。When the nozzle cover 400 is moved to the rear again, the connection mechanism 500 is disconnected from the nozzle body 300, and the nozzle body 300 and the nozzle cover 400 are formed in a separated state. Thereby, only the nozzle cover 400 is moved to the rear to the position (storing position) where the discharge opening 411 and the female washing discharge port 340 overlap each other with respect to the nozzle body 300 whose brake is restricted to move later. When the control mechanism of the body 20 retreats to the storage position when the nozzle cover 400 is retracted, the drive motor 114 is stopped.

<5>噴嘴裝置及衛生洗淨裝置之作用<5>The role of the nozzle device and the sanitary washing device

接著，就本第1實施形態之噴嘴裝置100及具有其之衛生洗淨裝置10之作用，一面參照第6圖、第7圖、第8(a)圖及第8(b)圖，一面說明。Next, the nozzle device 100 of the first embodiment and the sanitary washing device 10 having the same will be described with reference to Figs. 6, 7 and 8(a) and 8(b). .

Pattern diagram. Further, in the eighth (a) and eighth (b) drawings, hatching is attached to the gap 315 and the pressure communication chamber 316.

首先，流入至臀部洗淨流路310之洗淨水在該臀部洗淨流路310流淌之期間，以變速部323賦與渦旋成份(參照第6圖及第7圖)。經賦與渦旋成份之洗淨水以彎折部311及彎曲部313，流淌方向從水平方向變化至上方。First, the washing water that has flowed into the buttocks washing channel 310 flows through the buttocks washing channel 310, and the scrolling member 323 imparts a swirl component (see FIGS. 6 and 7). The washing water to which the vortex component is applied is bent in the horizontal direction to the upper side by the bent portion 311 and the curved portion 313.

接著，朝上方流淌之洗淨水如第8(a)圖之箭號A所示，流入至噴出流路312，而由於噴出流路312之小孔部321之流淌面積小於臀部洗淨流路310，故橫亙階差部314全周，產生旋渦。此時，產生之旋渦不同，根據水流在噴出流路之附著狀態，產生於階差部314產生之渦流之強度分佈，結果，壓力分佈於階差部314之圓周方向產生。Then, the washing water flowing upward is flowed into the discharge flow path 312 as indicated by the arrow A in Fig. 8(a), and the flow area of the small hole portion 321 of the discharge flow path 312 is smaller than that of the buttock washing flow path. 310, the traverse step portion 314 is circulated throughout the entire circumference. At this time, the generated vortices are different, and the intensity distribution of the eddy current generated by the step portion 314 is generated according to the state in which the water flow is adhered to the discharge flow path, and as a result, the pressure distribution is generated in the circumferential direction of the step portion 314.

在本第1實施形態中，特別是由於使噴出流路312於後端側傾斜，故後端側之旋渦B增強，前端側之旋渦B減弱。因此，噴出流路312之後端側之壓力增高，前端側之壓力減低。藉此，流入至小孔部321之洗淨水後端側形成為從形成小孔部321之壁面剝離之水流(箭號C)，前端側形成為附著於形成小孔部321之壁面之水流(箭號D)。In the first embodiment, in particular, since the discharge flow path 312 is inclined at the rear end side, the vortex B on the rear end side is enhanced, and the vortex B on the distal end side is weakened. Therefore, the pressure on the end side after the discharge flow path 312 is increased, and the pressure on the front end side is lowered. Thereby, the rear end side of the washing water flowing into the small hole portion 321 is formed as a water flow (arrow C) which is peeled off from the wall surface on which the small hole portion 321 is formed, and the front end side is formed to be attached to the water flow forming the wall surface of the small hole portion 321 (Arrow D).

此時，因在階差部314之後端側與前端側間產生壓力差，後端側之高壓力藉由間隙315，傳至壓力連通室316。傳至壓力連通室316之高壓力在該壓力連通室316內，以箭號E所示之方向之二次流傳遞(參照第8(b)圖)。傳遞至壓力連通室316內之前端側之高壓力藉由間隙315，傳至前端側之旋渦B’，旋渦B’之壓力增高。然後，藉前端側之旋渦B’之壓力增高，後端側之旋渦B之壓力減低，小孔部321之前端側之水流從形成小孔部321之壁面剝離，後端側之水流形成為附著於形成小孔部321之壁面之水流。At this time, since a pressure difference is generated between the end side and the front end side after the step portion 314, the high pressure on the rear end side is transmitted to the pressure communication chamber 316 through the gap 315. The high pressure transmitted to the pressure communication chamber 316 is transmitted in the pressure communication chamber 316 in a secondary flow in the direction indicated by the arrow E (refer to Fig. 8(b)). The high pressure transmitted to the front end side in the pressure communication chamber 316 is transmitted to the vortex B' of the front end side through the gap 315, and the pressure of the vortex B' is increased. Then, the pressure of the vortex B' on the front end side is increased, and the pressure of the vortex B on the rear end side is reduced, and the water flow on the front end side of the small hole portion 321 is peeled off from the wall surface on which the small hole portion 321 is formed, and the water flow on the rear end side is formed to adhere. The water flow on the wall surface of the small hole portion 321 is formed.

如此，藉替換水流之剝離與附著，階差部314附近之旋渦之產生及壓力亦變化，此次前端側之高壓力藉由由間隙315與壓力連通室316構成之壓力連通路徑317，以箭號F所示之方向之二次流，傳遞至後端側(參照第8(b)圖)。Thus, by the stripping and adhesion of the replacement water flow, the generation and pressure of the vortex near the step portion 314 also changes, and the high pressure on the front end side is caused by the pressure communication path 317 formed by the gap 315 and the pressure communication chamber 316. The secondary flow in the direction indicated by the number F is transmitted to the rear end side (refer to Fig. 8(b)).

在此種前端側及後端側，交互產生附著與剝離，藉反覆進行此動作，洗淨水形成為振動流，洗淨範圍擴大，同時，高速地於前後方向轉換，藉此，被分開而形成脈動狀態。On the front end side and the rear end side, adhesion and peeling occur alternately, and this operation is repeated, and the washing water is formed into a vibrating flow, and the washing range is expanded, and at the same time, the front-rear direction is switched at a high speed, thereby being separated. A pulsating state is formed.

又，於洗淨水從小孔部321流入至大孔部322時，由於以小孔部321及大孔部322形成之角之部份以峭立成約直角之稜狀形成，故在該部份附近進而產生旋渦(參照第8(a)圖)。藉此，在小孔部321，可將洗淨水之壓力變動進一步大幅地增大，而可賦與從臀部洗淨噴出口320噴出之噴流更強之脈動。因此，洗淨力可提高，並且，對人體產生強勁之洗淨之感覺。Further, when the washing water flows from the small hole portion 321 to the large hole portion 322, since the corner portion formed by the small hole portion 321 and the large hole portion 322 is formed in a ridge shape which is formed at a right angle, the portion is formed in this portion. A vortex is generated in the vicinity (see Fig. 8(a)). Thereby, in the small hole portion 321, the pressure fluctuation of the washing water can be further greatly increased, and the pulsation which is stronger from the jet flow discharged from the buttock washing discharge port 320 can be imparted. Therefore, the detergency can be improved, and a strong feeling of washing is generated to the human body.

如此，在本第1實施形態之噴嘴裝置100及具有其之衛生洗淨裝置10中，由於即使為具有複數個噴出口之噴嘴本體300，噴出開口411為1個即可，易附著污垢之處形成為最小限度，故可使清潔性提高。又，由於未使用側之噴出口以噴嘴蓋400覆蓋，故不致以因洗淨而髒污之洗淨水污染噴嘴本體300，而可使衛生面提高。而且，由於噴出開口411為必要最小限度，外觀亦簡潔，噴嘴蓋400亦為簡單之結構，故可謀求低成本化。In the nozzle device 100 and the sanitary washing device 10 according to the first embodiment, even if the nozzle body 300 has a plurality of discharge ports, the discharge opening 411 is one, and the dirt is easily adhered. It is formed to a minimum, so that the cleanability can be improved. Further, since the discharge port on the unused side is covered by the nozzle cover 400, the nozzle body 300 is not contaminated by the washing water contaminated by the washing, and the sanitary surface can be improved. Further, since the discharge opening 411 is required to be minimal, the appearance is also simple, and the nozzle cover 400 is also simple in structure, so that cost reduction can be achieved.

又，在第1實施形態之噴嘴裝置100及具有其之衛生洗淨裝置10中，由於噴嘴本體300及噴嘴蓋400為藉由連結機構500連動，而可切換相對位置之結構，故可以1個噴嘴驅動機構113將2個驅動對象驅動至各自之最佳位置，而可謀求裝置之小型化及低成本化。Further, in the nozzle device 100 of the first embodiment and the sanitary washing device 10 having the same, since the nozzle body 300 and the nozzle cover 400 are interlocked by the connecting mechanism 500, the relative position can be switched. The nozzle drive mechanism 113 drives the two drive targets to their respective optimal positions, thereby achieving downsizing and cost reduction of the device.

再者，在本第1實施形態之噴嘴裝置100及具有其之衛生洗淨裝置10中，藉以階差部314及壓力連通路317構成噴嘴裝置100之前端部，可形成為簡單之結構，而可謀求小型化，並且使在從臀部洗淨噴出口320噴出之洗淨水，以強勁之脈動噴出之洗淨水為脈動感強之振動流(噴流)，藉反覆進行對使用者之皮膚感覺之刺激，而可使使用者產生強勁之洗淨之感覺。Further, in the nozzle device 100 of the first embodiment and the sanitary washing device 10 having the same, the step portion 314 and the pressure communication path 317 constitute the front end portion of the nozzle device 100, and can be formed into a simple structure. In the case of miniaturization, the washing water sprayed from the buttocks washing and discharging port 320 is pulsating and pulsating, and the pulsating water is sprayed with a strong pulsation, and the skin is felt to the user. The stimuli give the user a strong sense of cleansing.

此外，在本第1實施形態，採用了橫亙形成臀部洗淨流路310之壁面之全周設間隙315的形態，但不限於此，於小孔部至少設2處即可。In addition, in the first embodiment, the gap 315 is formed on the entire circumference of the wall surface of the buttocks washing channel 310. However, the present invention is not limited thereto, and at least two holes may be provided in the small hole portion.

又，在本第1實施形態，噴嘴單元200以噴嘴本體300及噴嘴蓋400之2個構件零件構成，但不限於此，亦可僅以噴嘴本體300構成。In the first embodiment, the nozzle unit 200 is configured by two members of the nozzle body 300 and the nozzle cover 400. However, the present invention is not limited thereto, and the nozzle unit 300 may be configured only by the nozzle body 300.

又，在本第1實施形態中，為噴嘴本體300具有臀部洗淨之功能及女性洗淨之功能2個功能的結構，但不限於此，亦可為僅具有臀部洗淨或女性洗淨之單一功能的結構。Further, in the first embodiment, the nozzle body 300 has two functions of a function of washing the buttocks and a function of washing the female. However, the present invention is not limited thereto, and may have only the buttocks or the females. A single function structure.

再者，在本第1實施形態中，採用了於噴嘴裝置100使階差部314、壓力連通路徑317、變速部323、噴出流路312傾斜，及使噴出流路312以小孔部321及大孔部322形成段狀之形態，但不限於此，只要於噴嘴裝置100形成階差部314及壓力連通路徑317即可，是否要追加其他構成要件可隨意。Further, in the first embodiment, the nozzle device 100 is used to incline the step portion 314, the pressure communication path 317, the shifting portion 323, and the discharge flow path 312, and to make the discharge flow path 312 a small hole portion 321 and The large hole portion 322 is formed in a segment shape. However, the present invention is not limited thereto. It is only necessary to form the step portion 314 and the pressure communication path 317 in the nozzle device 100, and it is optional whether or not to add other components.

Further, the pressure communication chamber 316 is formed in a ring shape so as to surround the entire circumference of the discharge flow path 312.

此外，在本第2變形例採用了2個間隙315、315設成在噴嘴裝置100之前端側及後端側相互相對之形態，但不限於此。2個間隙315、315只要在噴出流路312之外部，且設成與臀部洗淨流路310連通，其設置之位置可隨意。Further, in the second modification, the two gaps 315 and 315 are provided so that the front end side and the rear end side of the nozzle device 100 face each other, but the present invention is not limited thereto. The two gaps 315 and 315 are provided outside the discharge flow path 312 and are provided to communicate with the buttocks washing flow path 310, and the positions of the two gaps 315 and 315 are arbitrary.
