BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sanitary washing apparatus for washing a human local part after stool, and more particularly, to a sanitary washing apparatus capable of performing efficient washing by changing the washing water flow and selecting a pattern of the washing classification.

As a sanitary washing apparatus of this kind for washing the human local parts, hot water is jetted from the cleaning nozzles having single or plural jet holes to clean the local parts, but in this case, the cleaning classification is a intensive steady flow. There was a strong sense of irritation due to a collision to the local part, and there was a case of giving a user an unpleasant feeling.

As a remedy for this, a cleaning device disclosed in Japanese Patent Application Laid-open No. 58-13688 is known as having a bubble in the washing water to obtain a soft feeling of cleaning. This apparatus is provided with an ejector nozzle which increases the flow velocity of the washing water near the ejection hole of the washing nozzle, and removes air from the negative pressure space generated by the high velocity flow ejected from the nozzle. It has an air suction part for suction mixing, and blows out the gas-liquid two-phase flow which mixed air into wash water from a nozzle hole, and realizes a soft washing feeling.

In this method, however, a soft cleaning feeling can be obtained, but there is a problem that the cleaning efficiency cannot be increased because there is no change in the flow of the washing water in the washed parts. In other words, cleaning of dirt attached to the cleaned parts includes a process in which the fluid penetrates into the joint portion between the surface to be cleaned and the dirt to reduce the binding force, and a process in which the cleaning fluid collides with the washed part to remove the dirt. This is because it is effective to shift the classification in the taxable government to increase the peeling effect. In addition, since it is a gas-liquid two-phase stream, it is a intensive classification, and thus, it is not possible to perform extensive washing adapted to human local parts. Therefore, in order to realize a high cleaning efficiency and a wide range of cleaning in such a cleaning apparatus, it is necessary to move the whole nozzle apparatus, so a special driving means is necessary, which leads to the complexity, the enlargement of the apparatus, and the high cost. .

On the other hand, it is proposed to satisfy both comfortable feeling and efficient washing by fluctuating the cleaning classification as disclosed in JP-A-63-152703. This sanitary washing apparatus is shown in FIG. 1 and FIG. In the same figure, reference numeral 1 denotes a toilet bowl, and a reference numeral 2 denotes a sanitary cleaning sheet, which protrudes into the sheet 3, the toilet lid 4, the main body 5 with a cleaning device, and the toilet 1, It consists of the washing | cleaning nozzle 7 which wash | cleans local parts of the human body 6. 2 shows the structure of the cleaning nozzle 7, where 8 is a throttle portion communicating with the fluid supply path 9, 10 is a spout port, and both sides are attached walls 11 and 12. There is this. In addition, (13) and (14) are vortex chambers formed on both sides with respect to the outflow direction of the jet, and each has atmospheric communication holes 15 and 16, respectively.

In the above configuration, when the washing water flows into the washing nozzle 7 from the main body 5 and is ejected from the throttle portion 8 via the fluid supply path 9, the fluid adhesion effect (Coanda effect) is used. For example, it adheres to the attachment wall 11 side and flows out to the arrow A side, and draws air from the atmospheric communication hole 15 in the vortex chamber 13, and forms a bubble mixing inlet. At the same time, the pressure in the vortex chamber 13 rises by air suction, and the flow direction is pushed toward B when the arrow is moved. By repeating this state, it becomes a self-oscillation state, and washing | cleaning of a human body part is performed, classifying fluctuating. That is, since the cleaning classification moves on the surface to be cleaned, the peeling effect on the dirt is increased, a high cleaning effect can be obtained, and a wide range of cleaning can be performed adapted to the human body part. In addition, since air is mixed, a soft washing feeling can be obtained.

As described above, however, in the washing apparatus, since the oscillation is stabilized by the pressure difference in the vortex chambers formed on both sides, in the low flow rate region, the ejection speed from the throttle portion 8 decreases, so that the pressure difference hardly occurs. In addition, since the deflection occurs in the bubble mixing vortex in the vortex chamber due to the change in the dimensional accuracy and the water supply state, there is a problem that oscillation in the low flow region becomes unstable, and improvement is desired.

On the other hand, since this type of washing apparatus has a plurality of users, the state of comfortable classification varies according to gender, age, individual difference, or physical condition, and it is desired to select a pattern of washing classification according to taste. As a countermeasure, the water flow of the washing water is configured to be adjustable in multiple stages. Thus, the pattern of the washing classification is the same, and it is not sufficient to meet the user's request.

On the other hand, in recent years, as shown in FIG. 3 and FIG. 4, what provided two or more types of cleaning nozzles with a different cleaning classification pattern is proposed (Japanese Patent Laid-Open No. 62-111038). In the figure, reference numeral 17 denotes a first anal cleansing nozzle which is cleaned in a classification capable of obtaining a relatively strong sense of irritation caused by normal flow, and reference numeral 18 denotes a softer and softer than the first anal cleansing nozzle 17. A second anal cleaning nozzle capable of performing a wide range of cleaning, and 19 is a third cleaning nozzle for cleaning the local part of the female. Reference numeral 20 denotes an operation panel shown in FIG. 4, and includes first, second, and third cleaning switches 21, 22, and (1) for starting the cleaning nozzles 17, 18, and 19, respectively. 23) and the stop switch 24, the water control switch 25, by selecting any one of the first, second, third washing switches 21, 22, 23, nozzle switching valve ( At the same time, 26 is selectively switched, the pump 27 supplies the water from the tank 28 to the hot water tank 30 through the hose 29 and discharges the water from the selected washing nozzle. According to this configuration, the cleaning classification pattern according to the user's taste can be selected by selecting any one of the first, second, and third cleaning switches 21, 22, and 23 according to taste. By adjusting the control switch 25, the pump 27 is controlled to be able to adjust the water sprayed to your liking.

However, in such a cleaning device, it is necessary to provide the cleaning nozzle and the nozzle switching means separately according to the type of cleaning classification as the nozzle for the anal, which leads to the complexity and the enlargement or the high price of the device.

SUMMARY OF THE INVENTION The present invention solves the problems as described above. The sanitary structure of the present invention can change the cleaning classification with a simple structure to realize a high cleaning efficiency and a wide range of cleaning, and to obtain a stable fluctuation classification even in a low flow rate region. The first object is to realize the cleaning device.

A second object is to realize a simple sanitary washing apparatus which can arbitrarily select the cleaning pattern according to the user's taste, such as the intensive classification by the normal stream and the classification which can spread the extensive washing | cleaning.

In order to achieve the first object, the sanitary washing apparatus of the present invention includes at least a washing water supply means, a water supply passage, and a washing nozzle for ejecting the washing water toward the human body part. A predetermined inclination angle is formed so as to have a plurality of ejection holes capable of ejecting the washing water supplied from the supply means, and a part or all of the axes of the plurality of ejection holes intersect between the end faces of the cleaning nozzles from the ejection end face. At the same time, turbulence generating means for ejecting the washing water discharged from the jet hole into different water flows is provided. The turbulence generating means generates a vortex in the washing water flow inside the nozzle to change the fluid pressure and to change the flow rate ejected from each jet hole, which is discharged from each jet hole to change the flow velocity of the jet, or Means such as mixing air into the water to generate turbulence in the fractionation can be used. As a result, when the washing water supplied from the washing water supplying means is ejected from each of the spray holes, each of the flows joins from the spraying end face of the washing nozzle between the parts to be cleaned. At this time, if the divided outputs of the respective flows that are joined are decomposed into a horizontal component and a vertical component with respect to the jetting direction, the respective jets are discharged in different states by the jetting speed, flow rate, and mixing of air by the turbulence generating means. The balance of the forces of the vertical components of the divided outputs is disturbed and changes irregularly, and the classification fluctuates. Therefore, the cleaning structure can be oscillated with a simple structure only by arranging the ejection hole at an inclined position and providing the turbulence generating means, thereby enhancing the effect of removing dirt from the cleaning surface, and achieving high cleaning efficiency. At the same time, a wide range of washings suitable for local washing of the human body can be performed. In addition, in the present invention, the swing width of the jet, that is, the washing range, can be easily adjusted by adjusting the inclination angle of the jet hole.

In addition, since turbulence is applied to each classification, fluctuations are realized by changing the force in the vertical direction irregularly with respect to the jetting direction, so that it is difficult to be affected by slight dimensional accuracy or change in water supply state, and thus a low flow rate region. In this case, a stable rocking state can be obtained.

In order to achieve the second object, the present invention has a washing water supply means, a water supply passage, and a plurality of ejection holes capable of ejecting the washing water supplied from the washing water supply means, A predetermined inclination angle is formed so that some or all axes intersect between the flushing end face of the cleaning nozzle and the cleaning part, and a cleaning nozzle for ejecting the cleaning water toward the human body part, and mixing air into the cleaning water. An air mixing means, an air mixing selection switch for selecting the presence and absence of air, and an air amount adjusting means for controlling the air mixing means based on a signal of the selection switch.

According to this configuration, by selecting the presence or absence of air intake by the air inlet selection switch, according to the user's preference, the cleaning classification pattern can be easily selected in the classification which enables the extensive and widespread cleaning according to the user's taste. It becomes possible. In other words, when air is not mixed, when the washing water supplied from the washing water supplying means is ejected from each jetting hole, the water flows from the spraying end face of the washing nozzle to the washing part, so that each classification is brought into contact at the intersection. do. At this time, when the divided outputs of the respective classes joined are decomposed into the horizontal component and the vertical portion with respect to the ejecting direction, the vertical components are balanced and are concentrated toward the human body. On the other hand, as the air is mixed, the washing water discharged from each jet hole is jetted in a different water flow state, the balance of the forces of the vertical components of the respective jet outputs is broken, irregularly changed, and the classification fluctuates. do. Therefore, with the simple structure of only controlling the mixing of air, it is possible to arbitrarily select the intensive cleaning by the normal flow and the extensive cleaning which is soft and suitable for local washing of the human body according to taste. As a result, it is possible to select the cleaning classification without using the dedicated cleaning nozzle and the switching means as in the conventional example. In addition, the application range of the air inlet position is wide. In other words, the air mixing position may be a supply system for the washing water, and remote control for washing classification selection can be easily performed. In addition, the present invention realizes a cleaning pattern in which concentrated washing and alternating washing in a wide range are realized by controlling the amount of air mixture, and the degree of freedom of selection is increased, and the intensity or change of the cleaning classification and the concentration or dispersion of the cleaning area are also realized. There is no forging feeling at the time of washing | cleaning, and since the peeling effect with respect to a dirt improves by this, washing power improves.

Moreover, the sanitary washing apparatus of this invention has the 1st, 2nd flow path which communicates with a washing | cleaning water supply path, and the 1st and 2nd blowing hole which communicates with 1st, 2nd flow path, respectively, This 1st And first and second jetting holes communicating with the second flow paths, respectively, wherein the axes of the first and second jetting holes intersect between the cleaning portions from the jetting end face of the cleaning nozzle. At the same time, the flow rate ratio control means for controlling the distribution ratio of the amount of washing water supplied to the first and second flow paths is provided.

According to the present invention, by controlling the distribution ratio of the flow rate of the washing water sprayed from the first and second spray holes by the flow rate ratio control means, extensive washing by the concentrated steady flow and the movement of the washing position is achieved. It is possible to easily select the pattern of the cleaning classification in the possible classification.

In other words, when the distribution ratio of the washing water sprayed from the first and second spray holes is controlled at the same rate, the washing water discharged from each spray hole crosses and joins at a predetermined position. At this time, if the divided outputs of the flows of the respective flows are decomposed into horizontal and vertical components in the jet direction, the vertical components of the jets of the jets of the first and second jet holes are balanced with each other and become a intensive steady flow, so that Erupted toward On the other hand, if the distribution ratio of the washing water is controlled and, for example, the ratio of the amount of washing water from the second jetting hole to the amount of washing water of the first jetting hole is increased, the balance of the vertical component of the jet is broken. , The output power from the second ejection hole is increased, and conversely, the output power from the first ejection hole is reduced. As a result, the collision position in the to-be-cleaned surface of the combined washing | cleaning classification moves to the 1st blowing hole. That is, it is possible to move the washing position by changing the distribution ratio of the washing water supplied to the first and second jet holes. Therefore, only by controlling the distribution ratio of the amount of washing water, it is possible to arbitrarily select intensive cleaning and a wide range of cleaning classifications suitable for human body parts, and to move the cleaning classification without moving the entire cleaning nozzle. As a result, it is possible to improve the peeling effect on dirt and simplify the construction. In addition, when the distribution ratio of the amount of washing water is controlled step by step, the washing classification can be moved to any washing position suitable for the user. That is, the washing position can be adjusted.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 5 shows a block diagram of the sanitary washing apparatus according to the first embodiment of the present invention. In the same drawing, reference numeral 31 denotes a motor 33 which is the driving means of the water pump 32. As shown in FIG. The washing water supply means 34 is a hot water tank for storing hot water heated by the electric heater 35, and 36 is a water supply passage for supplying the washing water. Reference numeral 37 denotes a nozzle body, which is driven by receiving nozzle water 39 in the nozzle cylinder 39 having a water supply port 38 communicating with the water supply passage 36 and the nozzle cylinder 39, and is driven to the local body position. The movable water supply body 42 and the washing water supply means 31 which stop and supply the washing water passing through the water supply passage 36 to the washing nozzle 41 provided at the distal end through the communication passage 40 are stopped. It has the elastic member 43 which moves the movable water supply body 42 to a retracted position when supply of wash water is stopped. As shown in FIG. 6 and FIG. 7, the cleaning nozzle 41 has a plurality of jet holes 45a which spray the cleaning water flowing into the nozzle chamber 44 toward the target part, that is, the human body part A}. And 45b, and at predetermined angles θn such that the axes of the ejection holes 45a and 45b intersect at the p point between the ejection end surface 46 of the cleaning nozzle 41 and the human body portion A. Incidentally, reference numeral 47 denotes a turbulence generating means for ejecting the washing water discharged from each of the ejection holes 45a and 45b to another state while incorporating air into the washing water. An air suction port for suction-mixing air from the negative pressure space generated by the high speed flow discharged from the axial flow nozzle 48 provided at the distal end of the axial flow nozzle 48 and the diffuser 49 and the axial flow nozzle 48 coaxially installed. The cleaning nozzle 41 is provided by the seal member 51 without being pulled out of the movable water supply body 42. Is attached to the end portion (52) is a water supply control means for controlling the supply of the washing water.

In the above configuration, the operation and operation of the present embodiment will be described next. When the washing start switch (not shown) installed in the water supply control means 52 is put in, the motor 33 is driven, and the washing water is supplied to the nozzle cylinder 39 via the hot water tank 34 by the water pump 32. Supplied, the hydraulic pressure of the washing water acts on the end face 42a of the movable water supply body 42, extrudes the starting water supply body 42 against the force of the elastic member 43, and stops and washes at the local body position. The water is released. At this time, the flow rate increases as the washing water passes through the axial flow nozzle 48, and the air is sucked and mixed from the air suction port 50 formed in the negative pressure space generated by the high speed flow, and the gas-liquid two-laminar flow into which water and air are mixed. The washed water is jetted from each of the jet holes 45a and 45b. The jetted washing water merges at the point p and contacts each other. At this time, the jet is blown into different irregular flow states by the air mixing from the turbulence generating means 47, and when the output of each jet at the confluence point is decomposed into a horizontal component and a vertical component with respect to the blowing direction, The balance of power is disturbed, changing irregularly, and the classification fluctuates. This will be described in more detail using FIG. 8. The discharge output of the jetting water 45a is set to Vm and the discharge output from the jetting hole 45b which is inclined is set to Va and Vb, and the jetting output of the jetting hole 45b is set to the jetting hole 45a. Decomposition into the horizontal components Va 1, Vb 1 and the vertical components Va 2, Vb 2 with respect to the classification causes air to mix and the washing water sprayed from the blowing holes 45a and 45b passes through the blowing holes, Each is ejected in a different state. As a result, as shown in FIG. 8, the balance between the vertical components Va2 and Vb2 is broken, and the classification fluctuates irregularly. As an example, the hole diameters of the ejection holes 45a and 45b are 1 mm and 0.75 mm, respectively, the pitch Pn is 10 mm, the inclination angle θ is 30 °, and the distance from the jet end 49 to the to-be-fixed part A is 52 mm. When the washing water amount was 0.8 L / min and the air mixing pressure was 0.2 L / min, the fluctuation width Wn in the to-be-cleaned portion A was 15 mm. In addition, it is possible to easily adjust the swing amplitude Wn by changing the inclination angle θn of the ejection hole 45b and the installation value of the pitch Pn. In other words, if the inclination angle θn is set to be large and Pn is set to be small, the swing amplitude Wn can be increased, and if set to the contrary, the swing amplitude Wn can be made small. The swinging speed is relatively high, and the swing speed can be adjusted by the amount of washing water, the bubble location diameter, the blowing hole diameter, and the like.

As described above, according to the present embodiment, the cleaning classification can be oscillated with a simple structure only by arranging the ejection hole at an inclination and providing the turbulence generating means 47, and peeling dirt from the cleaning surface. Since the effect can be heightened, high washing | cleaning efficiency can be obtained and a wide range of washing | cleaning suitable for local washing of a human body can be performed. In addition, by adjusting the inclination angle and pitch of the ejection hole, the swing width of the jet, that is, the washing range, can be easily adjusted. In addition, since turbulence is applied to each classification, fluctuations are realized by changing the force in the vertical direction irregularly with respect to the jetting direction, so that it is difficult to be affected by slight dimensional accuracy or change in water supply state, and thus a low flow rate region. In this case, a stable rocking state can be obtained.

9A and 9B show cross-sectional views of another embodiment of the cleaning nozzle 41. 9A shows cleaning water in the nozzle chamber 44 through the communication passage 40 of the movable water supply body 42 as turbulence generating means. A vortex generator 53 for generating vortices in the water stream as it passes through the axial flow sections 54a and 54b, and for ejecting different states of the washing water discharged from the respective jet holes 45; It is formed. Other than that is the same as the embodiment shown in FIG. 6, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

In this configuration, as shown in FIG. 9A, when the washing water flows into the nozzle chamber 44 via the communication path 40, it is classified into the first nozzle chamber 44a and the second nozzle chamber 44b. In the course of passing through the axial portions 54a and 54b, vortices are generated in the water flow by the shape effect. In other words, as the vortex occurs in the water flow, turbulence of the flow velocity occurs, and the pressure in the vicinity of the ejection hole 45 in the first and second nozzle chambers 44a and 44b is changed. The washing water is jetted from the holes 45 by different jet pressures. As a result, at the confluence point p, the balance of the force of the vertical component in the jetting direction of the jet is disturbed and changes irregularly, and the jet is oscillated. In this embodiment, the same effects as in the above embodiment can be obtained, and the axial nozzle 48, the diffuser 49, and the air suction port 50 become unnecessary, and the configuration can be simplified more.

9 (b) shows a vortex chamber which forms an axial flow portion 54c which communicates with the communication path 40 of the movable water supply body 42 as the turbulence generating means 47, and turns the washing water downstream thereof. 55 is formed, and since a vortex is formed in the vortex chamber 55, the atmospheric communication hole 56 which draws in air is formed and comprised. Other than that is the same as the embodiment shown in FIG. 6, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

In this configuration, as shown in FIG. 9 (b), when the washing water flows into the vortex chamber 55 through the axial flow section 54c, it becomes a swirl flow, and the central portion of the swirl flow becomes a negative pressure, thereby providing atmospheric communication holes. Air enters from 56 and blows out from each of the blowing holes 45a and 45b.

As a result, according to the principle similar to the embodiment shown in Fig. 6, at the confluence point of the jet, the balance of the force of the vertical component in the ejection direction is disturbed and irregularly changed, and the jet is oscillated.

In this embodiment, in addition to the effects of the above embodiment, turbulence is imparted to the jet by both vortices and air mixing, thereby enabling more stable fluctuation classification to be realized, and particularly excellent in the stability of fluctuations in the low flow rate region.

In the above configuration, the operation and operation of the present embodiment will be described next.

After the toilet, when the washing switch 68 is put in, the motor 33 and 59 start rotation by the first water supply control circuit 65, and the predetermined washing water is supplied by the water pump 32 to the hot water tank. (34) is supplied into the nozzle cylinder (39) via the water supply port (38), and the hydraulic pressure of the washing water acts on the end face of the movable water supply body (42) to start advancing against the force of the elastic member (43). . In addition, at this time, the movable plate 62 provided in the outer peripheral part of the air supply pipe 60 closes the communication path 40, and it is in the nozzle cylinder 39 with the movable rapid chute 42 by hydraulic pressure. It is extruded toward the cleaning nozzle 41. When the cleaning nozzle 41 reaches the local body position, the movable plate 62 is stopped in contact with the stopper 63, and the communication path 40 is opened as shown in FIG. Pass). On the other hand, the water pump 32 operates and the air pump 58 also operates, and the compressed air enters the washing water from the open end 61 into the washing water at a predetermined ratio via the check valve 64 and the air supply pipe 60. The washing water mixed with bubbles flows into the washing nozzle 41. At this time, air is mixed in the process of passing through the communication path 40, that is, near the cleaning nozzle 41, so that the air bubbles of the washing water after the air mixing are rapidly expanded and contracted without mixing. Unevenness of the bubble diameter caused by this can be prevented, and bubbles having a stable particle diameter are supplied to the nozzle chamber 44. Moreover, in the communication path 40, the flow rate of the washing water passing around the opening end portion 61 increases due to the reduction of the passage area thereof, and the pressure of the opening end portion 61 due to the ejector effect caused by the passage of the washing water. Since it can be reduced, air can be mixed at low pressure. This enables forced mixing of air with an air pump of low discharge pressure.

The gas-liquid two-phase flow which flowed into the nozzle chamber 44 is ejected from each jet hole 45a, 45b, and as shown in FIG. 10 by the principle similar to the Example shown in FIG. It is possible to obtain a soft cleaning sensation by shaking and mixing of bubbles, and at the same time, it is possible to obtain a wide range of cleaning classifications suitable for improving cleaning efficiency due to shaking and washing of local parts of the human body. In addition, as described above, since the large diameter of the bubble diameter due to the mutual bonding of the bubbles can be prevented, and the bubbles having a stable particle diameter can be supplied, the popping sound of bubbles at the time of blowing can be reduced.

Next, the water control operation will be described. After the cleaning switch 68 is put in, the water control switch 69 can be operated to arbitrarily adjust the amount of washing water sprayed from the water, ie, the cleaning nozzle 41, according to the user's preference. 11 is a characteristic diagram showing the relationship between the water current, the flow rate of the washing water and the air, and in this embodiment, five levels of adjustment are possible. Here, immediately after the washing start, that is, immediately after the washing switch 68 is put in, the intermediate water level 3 is automatically selected, and the washing water QW and the air amount Qa are supplied to the washing nozzle 41. This is to reduce the user's switch operation frequency. As shown in FIG. 11, the mixing ratio of the washing water and the air is changed depending on the water current. This is to prevent the absolute value of the force components Va2 and Vb2 perpendicular to the cleaning classification shown in FIG. 8 from decreasing in the low flow rate region and reducing the swing width of the cleaning classification. As a result, even in the low flow rate region, the fluctuation width similar to that of the large flow rate region can be realized.

Next, the operation of the second hand control circuit 71 will be described. After the cleaning switch 68 is inserted, when the first flow selector switch 72 is input, the water flow control switch 69 is instructed to CanCel to stop the air mixing stop means 73 to stop the air pump 58. The mixing of air is stopped. At this time, the washing water flows back through the air supply pipe 60, but the back flow is prevented by the check valve 64. As a result, only the washing water is supplied to the washing nozzle 41, and as shown in FIG. 12, the washing water sprayed from each of the ejection holes 45a and 45b has a concentrated classification that does not join and swing. And is released toward the tax administration. This will be described in more detail using FIG. 13. The discharge power of the washing water from the jet hole 45a is decomposed into the horizontal components Va1, Vb1, and the vertical components Va2, Vb2 for the classification of the jet holes 45a with the discharge power from the jet hole 45b formed by inclining Vm. In this case, since air does not mix, the vertical components Va2 and Vb2 are balanced and concentrated as shown in FIG.

At the same time, the water quantity adjusting means 66 is controlled by the water quantity increasing means 74, so that the rotation speed of the water pump 32 increases and the flow rate of the washing water increases. This will be described in more detail using FIG. 14. When the cleaning switch 68 is turned on at time t ₀ , the water pump 32 and the air pump 58 are operated so that the washing water Qm and the air Qa are supplied to the washing nozzle 41 to obtain a fluctuation classification in which bubbles are mixed. Can be. On the other hand, when the first flow dividing selection switch 72 is input at time t ₁ , the supply of air is stopped, and on the contrary, the washing water is increased to Qv. This stops the supply of air, and on the contrary, the washing water is increased to Qv. This is to compensate for the deterioration of the feeling of washing by decreasing the amount of air. That is, in the air mixing and washing, the flow rate ejected from the washing nozzle 41 is the sum of the washing water and the amount of air and is set at a flow rate at which a predetermined washing feeling can be obtained when contacting the human body part. When this stops, the real flow rate decreases and the feeling of washing decreases. Therefore, when the cleaning that does not mix air is selected, it is necessary to increase the cleaning water. In addition, the intensive strong classification impinges on the anal part, thereby stimulating the anal part, thereby facilitating the urge to stool. In addition, in the case of requesting the rocking cleaning due to air mixing again, the first classification selecting switch 72 is modified to return to the initial state. In other words, by controlling the presence or absence of air mixing by operating the first classification selector switch 72, the intensive classification of the swing classification can be easily selected.

Next, the operation of the third hand control circuit 75 will be described. After the cleaning switch 68 is inserted, when the second flow dividing selection switch 76 is input, the air pump 58 is controlled by the swing control means 77, and the amount of air mixed into the washing water is shown in FIG. As indicated, it is increased or decreased in the range of Q _max by a predetermined additional fa. As a result, the fluctuation cleaning by the mixing of air and the intensive cleaning classification by continuous steady flow are automatically repeated. The effect is further improved, the washing power is improved, and the massage effect of the washed part can be obtained. Moreover, it does not give a user the monotonous feeling of the cleaning company. In addition, the upper limit Q _max and the lower limit Q _min of the amount of air controlled by the swing control means 77 are automatically controlled by the air control limit setting means 78 according to the water flow set by the user by the water control switch 69. Is set. FIG. 16 is a characteristic diagram showing the relationship between the upper and lower limits of water current and air. For example, if the current level 3 is selected, the air amount increases or decreases in the range from the upper limit Q _max to the lower limit Q _min . Thereby, the washing | cleaning sensation suitable for each water can be obtained. In addition, when the stop switch 70 is inserted, the cleaning operation is stopped.

As described above, in the present embodiment, the first jetting selector 72 and the mixing nozzle for selecting the presence or absence of air mixing are provided while providing the cleaning nozzle 41 which can obtain the shaking classification by mixing air into the washing water. A second flow splitter switch 76 for periodically changing the amount of air to be provided is provided.

By the selection of the first flow dividing selection switch 72, the fluctuation classification and the intensive classification in which air is mixed can be easily selected according to the user's taste. Especially, when the intensive classification is selected, the flow rate of the washing water is adjusted. Since the increase in water quantity increasing means 74 is provided, it is possible to prevent the deterioration of the feeling of washing due to the stop of air mixing, and to stimulate the anal part by intensive strong classification impinging on the anal part, thereby promoting the desire for stool. Can also be obtained.

In addition, the air mixing amount is increased or decreased by the selection of the second sorting selector switch 76 so that the intensive washing classification by the rocking washing and the continuous steady flow is automatically repeated, and the strong / weak change of the cleaning classification and the concentration of the cleaning area / By dispersion, the massage effect of the taxable part can also be obtained. Moreover, since the upper and lower limits of the air increase and decrease amount are set in accordance with the water stream selected by the user, an appropriate cleaning sensation can be obtained in accordance with each water stream.

In addition, when the cleaning starts, that is, when the cleaning switch 68 is turned on, the cleaning is started by the shaking classification with air mixed therein, so that the user does not have a strong sense of intensive classification at the beginning of the cleaning. This is especially suitable for patients with hemorrhoids.

The tank 36 is a water supply passage for supplying washing water. Numeral 37c is a nozzle body and is driven in and out of the nozzle cylinder 39 having the first and second water inlets 38a and 38b. It consists of the movable water supply agent 42a which ejects toward the human body part from the washing nozzle 41a provided in the one end part. The movable water supply body 42a is provided with valve members 82a and 82b for preventing leakage of the washing water to the outside of the nozzle at the advanced position, and is provided in the middle of the valve members 82a and 82b. The water supply port 38b is formed. In addition, the movable water supply body 42a has a first flow path 83 that communicates with the first water supply port 38a at the advancement position, and a second flow path 84 that communicates with the second water supply port. As shown in detail in FIG. 19, the first and second ejection holes 45a formed at an angle and inclined at an angle θn such that an axis line intersects between the ejection end surface 49 of the cleaning nozzle and the to-be-fixed portion A, respectively. ) And (45b).

85 is provided downstream of the hot water tank 34, and flow rate ratio control which distributes and supplies the wash water supplied from the wash water supply means 31 to the 1st flow path 83 and the 2nd flow path 84. As shown in FIG. It is a valve, the sectional drawing in FIG. 20 is shown, and the XX sectional drawing of FIG. 20 is shown in FIG. That is, 86 is a housing, and the water inlet port 87 which communicates with the hot water tank 34, and the 1st and 2nd water outlet ports 88a and 88b which branched and installed from the water inlet port 87, respectively, are provided. The first water outlet port 88a communicates with the first water supply port 38b. 89 is a valve cock rotatably provided in the housing 86. The inlet port 87 and the first and second outlet ports 88a are formed by forming a cutout 90 formed in a part of the cylinder. ), 88b is provided with a passage 91 for selectively communicating. Reference numeral 92 is a seal member that is formed of a polymer material containing ethylene tetrafluoride, and is integrally formed with the valve cock 89. The polymer material containing tetrafluoroethylene has a small coefficient of friction and high elasticity, realizes smooth rotation of the valve cock 89, and prevents leakage of the control fluid to the outside. 93 is a drive means of the valve cock 89, and is comprised by the stepping motor 94, the speed reduction means 95, and the motor shaft 96 inserted in the valve cock 89. As shown in FIG.

The water supply control circuit 65a is a water supply control circuit, which controls the washing water supply means 31 by the operation of the water control switch 69 to adjust the water supply adjusting means 66 and the flow rate control valve 85 for adjusting the supply amount of the washing water. It has a flow rate control means 97 for controlling. The flow rate ratio adjusting means 97 outputs a signal to the stepping motor 94 to rotate the valve cock 89, and the first and second predetermined amounts of the washing water supplied by the washing water supply means 31 are adjusted. It distributes to the flow paths 83 and 84. FIG. 22 shows the relationship between the rotation angle θa of the valve cock 89 and the ratio of the flow rate Q ₁ to be distributed to the _first flow path 83 and the flow rate Q ₂ to be distributed to the _second flow path 84. When the rotation angle θb in FIG. 21 is zero, the same amount of flow is distributed to the first and second outlet ports 88a and 88b, and when the valve cock 89 rotates toward θa, The flow rate to the water outlet port 88a increases and the flow rate to the second water outlet port 88b decreases. On the contrary, when it turns to (theta) b side, the flow volume to the 1st water extraction port 88a will decrease, and the flow volume to the 2nd water extraction port 88b will increase.

Reference numeral 98 denotes a swing selection switch. When this switch is input, the flow rate discontinuous variable stage 99 is operated to output a signal to the flow rate adjusting means 97, and the valve cock 89 is driven by the driving means 93. 21 is also a continuous positive reversed alternately in the range of θa ~ θb shown in, the first and the oil channel 83, the flow rate Q _1, the ratio of Q ₂ to be supplied to the 84 of the second continuously increased or decreased as. In addition, 100 is a position control switch having forward and backward switches 101 and 102, and the flow rate intermittent variable stage 103 is operated whenever the main switch is operated to output a signal to the flow rate control means 97. The stepping motor 94 rotates by a predetermined angle so that the valve cock 89 is intermittently rotated in the range of? A to? B.

104 is an initial setting means, even when the cleaning switch 68 is input, and the water flow rate and flow rate ratio according to the user's preference are set, the water flow adjusting means 66 is standardized when the stop switch 70 is input. The flow rate ratio adjusting means 97 returns to the zero position where the rotation angle θ of the valve cock 89 is shown in FIG. 21, and the cleaning operation is completed. Therefore, when the washing | cleaning switch 68 is input, washing | cleaning is started based on an initial setting condition.

In the above configuration, the operation and operation of the present embodiment will be described next. When the washing switch 68 is input, the washing water supply means 31 operates under the conditions set by the initial setting means 104, and the washing water flows into the flow rate control valve 85 via the hot water tank 34. Here, the valve cock 89 of the flow rate ratio control valve 85 is set at the position of rotation angle 0 as shown in FIG. 21, and is supplied to the supply amount from the first and second outlet ports 88a and 88b. It distribute | distributes by the same rate, ie, 50%, and supplies it to the 1st, 2nd flow path, and blows out from the 1st, 2nd blowing holes 45a, 45b. Since the jet holes 45a and 45b are formed inclined at an angle of, the jetted washing water joins at the point p and becomes concentrated as shown by the solid line in FIG. And the washing is performed. In addition, by the operation of the water control switch 69, the water can be selected according to the user's taste. Also,

The washing position at this time may not be optimal depending on individual differences and seating positions. In such a case, for example, when the cleaning classification is to be moved forward with respect to the user, when the forward switch 101 of the position control switch 100 is inserted once, it is applied to the output signal from the flow rate ratio interruption variable stage 103. As a result, the flow rate ratio adjusting means 97 operates, and as shown in FIG. 22, the valve cock 89 of the flow rate ratio control valve 85 is driven by a predetermined angle θb1 rotation in the direction of θb from the position of the rotation angle 0, The flow rate Q ₁ supplied to the first flow path 83 decreases, while the flow rate Q ₂ supplied to the _second flow path 84 increases. As a result, as shown in FIG. 19, the power output from the 2nd blowing hole 45b becomes strong, and the washing | cleaning position by a classification | movement moves to the direction of F (front side with respect to a user) at the time of an arrow. In addition, if it is desired to move forward, it is possible to operate the forward switch 101 again so that the rotation angle is θ b2. It is possible.

Next, the operation of the flow rate continuous variable stage 99 will be described. After the cleaning switch 68 is input, when the swing select switch 96 is input, the flow rate continuous variable stage 9 is operated to output a signal to the flow rate control means 97, and the valve cock of the flow rate control valve 85 is turned on. Alternately reversed and reversed in the range of θb (89) shown in FIG. 21, and the ratios of the flow rates Q ₁ and Q ₂ supplied to the first and second flow paths 83 and 84 continuously increase and decrease. do. As a result, the washing water sprayed from the first and second spray holes 45a and 45b alternately and continuously increases and decreases. As shown in FIG. 19, when the Q ₁ increases, the washing position is indicated by an arrow. When Q ₂ increases in the direction of the time B and moves in the direction of the F at the time of the arrow, and these are repeated alternately, a wide range of washing due to the fluctuation of the classification is possible. In addition, the swing width Wn of the jet is proportional to the inclination angles θb of the ejection holes 45a and 45b. When the inclination angle θb is set to be large, the swinging width Wn or the position adjustment width can be set large. In addition, the swing period in the swing cleaning depends on the operation speed of the flow rate control valve 85, that is, the rotation speed of the stepping motor 94, and the reduction ratio of the deceleration means 95.

As described above, the present embodiment forms the first and second jetting holes 45a and 45b which are capable of contact-joining while inclining a predetermined angle with respect to the jetting direction, and at the same time, each jetting hole 45a, The two flow paths 83 and 84 are formed corresponding to 45b, and the flow rate ratio control valve 85 which controls the ratio of the flow volume supplied to these flow paths 83 and 84 is provided, and blows off. By controlling the flow rate ratio ejected from the holes 45a and 45b at the same rate, an intensive cleaning classification can be obtained, and the fluctuation selection switch 98 is selected, whereby the flow rate ratio is continuously changed and a wide range of cleaning can be performed. It is possible to select the fluctuation classification. For this reason, the optimal cleaning classification can be easily selected according to the condition, age, and taste of the user's body.

In addition, by operating the position control switch 100, the washing position can be adjusted by adjusting the flow rate step by step. This makes it possible to adjust the cleaning position without moving the entire nozzle body 37C, thereby simplifying the constitution and improving the cost and reliability.

In addition, since the initial setting means 104 is provided, the conditions of use of the previous place of use are canceled, and since the washing starts at a predetermined water and washing position at the start of use, unnecessary switch operation by the user is reduced. This is suitable for this kind of sanitary washing apparatus having a plurality of users.
