[0022]
【Example】
A first embodiment of the present invention will be described with reference to FIGS. That is, FIG. 1 shows an overall view of the sanitary washing device. This sanitary washing device mainly has a water supply means 1 which is a variable water force means, a washing nozzle 2, and further has a heating means 3 and a washing area variable means 4 which is a washing area variable means. Describing in detail along the flow of the washing water, the water supply source valve 5, the relief valve 6, the flow sensor 7, the heating means 3, the water supply means 1, the washing area variable means 4, and the washing nozzle 2 are sequentially connected. The water supply valve 5, the flow sensor 7, the heating means 3, the water supply means 1, and the washing area variable means 4 are controlled by a control circuit 8, which is operated by an operation means 9.
[0023]
The water supply means 1 is, for example, a pump. In the embodiment, a displacement type pump capable of intermittent pressurization and discharge described later is used. By changing the discharge amount of the pump, the water force ejected from the washing nozzle 2 can be changed. Configuration.
[0024]
The washing nozzle 2 is connected to the water supply means 1 and ejects washing water. The washing nozzle 2 according to the embodiment has a nozzle cylinder 10 which is a fixed portion, and a rear end portion moves into the nozzle cylinder 10. A movable nozzle 11 which is a freely movable portion. The nozzle cylinder 10 is provided with a first water supply port 17 at a rear end, a second water supply port 18 at a side portion, and a front end of the movable nozzle 11 protruding from a front end. The movable nozzle 11 has a first flow path 13 and a second flow path 14 that are continuous with the ejection port 12 at the tip, and the first flow path 13 and the second flow path 14 And a first passage 15 and a second passage 16 communicating with the first passage 15. The first flow path 13, the second flow path 14, the first passage 15, and the second passage 16 are formed integrally with the movable nozzle 11. In the state shown in FIG. 1, the first water supply port 17 communicates with the end 15 a of the first passage 15, the second water supply port 18 communicates with the end 16 a of the second passage 16, and the washing water is supplied from the jet port 12. It is gushing.
[0025]
The heating means 3 heats the washing water on the upstream side of the water supply means 1. In the embodiment, a momentary type in which the heater is energized only during use is described. That is, when water is detected by the flow sensor 7, the heater is energized to instantaneously heat the water.
[0026]
The cleaning area variable means 4 continuously varies the area where the cleaning water jetted from the cleaning nozzle 2 comes into contact with the human body, which is the surface to be cleaned. In the embodiment, the control circuit 8 controls the first passage as will be described later. The flow control valve also serves as a switching valve that switches between the first and second passages 15 and 16.
[0027]
The relief valve 6 is for discharging water other than the water discharged from the washing nozzle 2 to the outside of the water supply passage, and the flow rate sensor 7 is for detecting the incoming water and detecting the amount of washing water to control the heating means 3. Here, instead of the relief valve 6, a flow regulating valve that can be controlled by the control circuit 8 may be used to change the amount of water discharged to the outside of the water supply passage so as to make the water force variable.
[0028]
When the washing request signal is detected by operating the operating means 9, the water supply source valve 5 is opened by the control circuit 8, and the heating means 3 is energized and the water supplying means 1 operates. Then, the washing water is introduced into the heating means 3 and heated, and is fed under pressure by the water supply means 1. The washing water is selectively supplied to the first passage 15 and the second passage 16 via a flow control valve which is the washing area variable means 4 as described later. Alternatively, water is supplied at an arbitrary flow ratio. The water supply nozzle 2 ejects washing water from the ejection port 12 via the first flow path 13 and the second flow path 14, and cleans, for example, a predetermined part of a human body.
[0029]
FIG. 2 is a detailed view of the water supply nozzle. The nozzle cylinder 10 has two steps 20 and 21 in the moving direction of the movable nozzle 11, and has a second water supply port 18 between the steps 20 and 21. The movable nozzle 11 has a pair of seal portions 22 and 23 that move to a predetermined position in the nozzle cylinder 10 and are in close contact with each of the step portions 20 and 21, and a second water supply port is provided between the pair of seal portions 22 and 23. An end 16a of the second passage 16 which can communicate with the opening 18 is opened. The first passage 15 has an opening at the rear end 15a of the movable nozzle 11 so as to communicate with the first water supply port 17 formed at the end of the nozzle cylinder 10 through the inside of the nozzle cylinder 10. In addition, the movable nozzle 11 is in the retracted position between the movable nozzle protruding side end in the nozzle cylinder 10 and the rear end of the movable nozzle 11 via an elastic member 24 using a coil spring externally fitted to the movable nozzle 11. It is urged in a direction approaching the first water supply port 17.
[0030]
When water is supplied into the nozzle cylinder 10 from the first water supply port 17 and the second water supply port 18 in the state of FIG. 2, the first passage 15, the second passage 16, the first flow path 13, and the second flow At the same time as flowing out of the jet port 12 from the passage 14, when the water pressure is low, water flows out as shown by arrows through clearances 25 and 26 formed between the outer peripheral surface of the movable nozzle 11 and the inner peripheral surface of the nozzle cylinder 10, It flows to the tip along the peripheral surface of the movable nozzle 11. Thereby, the tip of the movable nozzle 11 is cleaned. When the water supply pressure sent from the water supply means 1 increases, the water pressure at the rear end of the movable nozzle 11 in the nozzle cylinder 10 becomes larger than the elasticity of the elastic member 24, and the movable nozzle 11 becomes elastic by the water pressure. The movable nozzle 11 is pushed out against the nozzle cylinder 10 to push the movable nozzle 11 against the stepped portion 20, and the seal portion 22 is in close contact with the step portion 20, and the seal portion 23 is in close contact with the step portion 21, and the state of FIG. As a result, the flow from the first water supply port 17 to the clearance 26 is prevented by the seal portion 22, and the flow from the second water supply port 18 to the clearance 26 is prevented by the seal portion 23. Therefore, the gas is ejected only from the ejection port 12 through the first passage 15 and the second passage 16. In this way, the movable nozzle 11 is configured to advance from the retracted position to the cleaning position by water pressure. Further, the second flow path 14 of the cleaning nozzle 2 forms a valve section to which cleaning water is supplied by sealing the step portions 20 and 21 by the seal portions 22 and 23 at the cleaning position.
[0031]
It should be noted that the first passage 15 communicates with the second water supply port 18 and the second passage 16 communicates with the first water supply port 17 in a configuration reverse to the above, and the washing water is supplied at the washing position. A configuration may be used.
[0032]
FIG. 3 is a longitudinal sectional view of the ejection port 12 in which the first flow path 13 and the second flow path 14 communicate with each other, and FIG. 4 is a transverse sectional view thereof. The cleaning nozzle 2 has a first flow path 13 and a second flow path 14 communicating with a single jet port 12, and a jetting direction in which the cleaning water flowing through the first flow path 13 jets from the jet port 12. And a rotating flow generating means 75 for applying a rotating force rotating around the rotating shaft. The rotary flow generating means 75 includes a second flow path 14 that forms a cylindrical vortex chamber provided coaxially with the ejection port 12, and supplies cleaning water in the second flow path 14 in a direction tangential to the outer circumference. The first flow path 13 communicates with the supply port 28. As a result, the washing water is supplied to the first flow path 13 at a flow rate Q1, for example, and the washing water is supplied to the second flow path 14 at a flow rate Q2 and mixed in the second flow path 14, as described later. Thus, a fountain whose outer peripheral surface spirally rotates around the axis is obtained. In this way, the washing water is mixed with the washing water that travels straight and the washing water that has been applied with a rotating force that rotates around the straight traveling direction, and is jetted out. On the other hand, it is mixed and ejected to the peripheral surface.
[0033]
The tip of the movable nozzle 11 is provided with the upper cap 31 provided with the ejection port 12, the first flow path 13, the second flow path 14, and the rotating flow generation means 75 because of the ease of the manufacturing process, especially injection molding. A nozzle main body 32 having a part of the first flow path 13 or the second flow path 14 opened on the side opposite to the upper cap 31; and a first flow path of the nozzle main body 32 which is closed to the nozzle main body 32. It comprises a lower cap 33 that seals a part of the opening of the part 13 or the second flow path 14. It should be noted that a configuration reverse to that described above in which the washing water from the second flow path 14 is supplied to the rotary flow generation means 75 instead of the first flow path 13 may be used.
[0034]
FIG. 5 is a cross-sectional view of a flow path for explaining the principle of generating a rotating flow, and FIG. 6 is a cross-sectional view taken along line AA. First, the washing water is spouted from the spout 12 as it is through the second flow path 14. The washing water that has entered the second flow path 14 from the supply port 28 through the first flow path 13 flows in one circumferential direction in the second flow path 14 along the inner peripheral surface. While rotating along the inner peripheral surface of the passage 14, the gas is ejected from the ejection port 12 so as to release the pressure in the second flow path 14, and the centrifugal force acts on the outside of the ejection port 12 by the rotational force as described above. The washing water spreads radially.
[0035]
In this case, when the flow rate Q1 is large and the flow rate Q2 is small, the rotation of the washing water becomes strong and the radially spreading angle becomes large. Conversely, when the flow rate Q1 is small and the flow rate Q2 is large, the radially spreading angle becomes small and the straight traveling becomes strong. Therefore, when the flow rate is continuously changed while the overall flow rate is kept constant, the angle of radial expansion changes, and the area corresponding to the surface to be jetted changes. In the case of the human body, when the cleaning area changes, the sensation intensity also changes at the same time.
[0036]
In particular, when the flow rate ratio is continuously changed, for example, in an inversely proportional relation, the strongest and the washing area can be continuously changed from the straight washing water having a small washing area to the weakest rotating washing water having a large washing area. When washing water is applied to the human body, the perceived intensity can be continuously changed.
[0037]
However, in a configuration in which the sensation intensity is changed only by the washing area, the amount of water discharged from the washing nozzle 2 is constant. Therefore, if the washing area is increased, the sensation intensity is weakened. I couldn't answer the needs of users who wanted to. In addition, it is known that by reducing the washing area and stimulating the dentate line in the anus, it is possible to promote bowel movements.However, reducing the washing area increases the water force, so it is used for hemorrhoids. I couldn't.
[0038]
Therefore, in the present invention, in the configuration in which the discharge amount of the pump, which is the water pressure varying means, that is, the water supply means 1, is variable, the flow ratio between the flow rate Q1 and the flow rate Q2 is variable. With this, it is possible to select a washing pattern in which the washing area is large and the water force is strong, or the washing area is small and the water force is weak, so that the needs described above can be met.
[0039]
In addition, the control circuit 8 causes the cleaning area variable means 4 and the water pressure variable means (water supply means 1) to interlock with each other, so that the cleaning area is increased by the cleaning area variable means 4 and at the same time the water pressure is increased by the water variable means. By performing the above, the cleaning area can be changed without changing the cleaning sensation intensity, so that the user can change the cleaning area without feeling uncomfortable.
[0040]
In addition, the supply port 28 may be inclined in the tangential direction and the axial ejection direction, and in this case, the ejection speed can be increased.
[0041]
FIG. 7 shows a cleaning area variable unit 4 that controls the flow ratio of the cleaning water supplied to the first passage 15 (first flow path 13) and the second passage 16 (second flow path 14) of the cleaning nozzle 2. It is sectional drawing of the control valve which is a flow control means. 35 is a cylindrical housing, 36 is formed at the tip of the housing 35 and is a connection port to the water supply side, that is, the heating means 3, and 37 is a connection for connecting to the first passage 15 formed on the peripheral surface of the housing 35. The port 38 is a connection port for connecting to the second passage 16 also formed on the peripheral surface of the housing 35, and the port 39 is connected to a flow path of a bidet cleaning nozzle (not shown) also formed on the peripheral surface of the housing 35. A connection port for connection. Reference numeral 40 denotes a cylindrical valve body rotatably fitted to the inner peripheral surface of the housing 35, and an elastic seal member 41 interposed between the connection ports 36 to 38 on the outer peripheral surface and the position of the base end of the valve body 40. Configuration. Reference numeral 42 denotes a concave portion formed at the end of the valve body 40, and is opened at the distal end so as to communicate with the water supply side connection port 36. Reference numeral 43 denotes a hole connecting the concave portion 42 and the bidet connection port 39, reference numeral 44 denotes a hole connecting the first passage 15 and the second passage 16, and the holes 43 and 44 are provided to be shifted in the rotation direction and the axial direction. . Reference numeral 45 denotes a driving unit using a motor or the like, which is attached to the end of the housing 35, and a connecting shaft 45a is connected to the base end of the valve body 40 so as to rotate the valve body 40. At the base end of the valve body 40, there is also provided a protruding portion 46 which is in contact with one end surface (not shown) of the housing 35 to set the origin position of the valve body 40. The drive unit 45 is controlled by the control circuit 9. FIG. 7 shows a communication state between the bidet connection port 39 and the hole 43. When the valve body 40 rotates by a predetermined amount due to the operation of the driving unit 45 and the hole 43 and the connection port 39 are disconnected, water supply to the bidet nozzle is stopped. You.
[0042]
FIG. 8 is a cross-sectional view showing control of the first passage 15 and the second passage 16. That is, the hole 44 communicates with the first passage 15 and the second passage 16 through the substantially partial spiral groove 49 formed on the outer peripheral surface of the valve body 40. This groove shape is formed so that the following operation is performed. That is, FIG. 8A shows a case where the valve shaft rotation angle of the valve body 40 with respect to the connection port 37 of the hole 44 is θ1, and the connection port 37 and the hole 44 communicate with each other through the groove 49 to connect the second passage 16. The port 38 and the hole 44 are not in communication. Therefore, washing water is supplied to the first passage 15. FIG. 8B shows a case where the valve body 40 is rotated and the angle becomes θ2, the connection port 37 of the first passage 15 is closed by about half, and the connection port 38 of the second passage 16 is open. It is. Therefore, the supply of the washing water to the first passage 15 is reduced by half, and the supply of the second passage 16 is performed. FIG. 8C shows a case where the valve body 40 further rotates to reach the angle θ3, and the connection port 37 of the first flow path 13 is completely closed. Therefore, the washing water is supplied to the second passage 16.
[0043]
FIG. 9 shows the flow ratio Q to the valve shaft rotation angle θ of the valve element 40. As is clear from FIG. 9, the flow ratio of the flow rate Q1 to the first flow path 13 and the flow rate Q2 to the second flow path 14 is almost inversely proportional. As a result, when the flow rate ratio is continuously changed, the spread angle of the washing water spouting radially from the ejection port 12 is changed as described above, so that the washing area is continuously changed.
[0044]
FIG. 10 shows a positive displacement pump capable of intermittent pressurization and discharge as the water supply means 1 for supplying cleaning water to the cleaning nozzle 2. The water supply means 1 includes a gear 57 which is rotated by being engaged with a gear 56 of a motor 55, a link mechanism 60 which is connected to the gear 57 and converts a piston 59 provided in a cylinder 58 into a reciprocating motion, and a pair of reverse mechanisms. The stop valve 61 is used. When the motor 55 rotates, the piston 59 reciprocates via the gear 57 and the link mechanism 60, and the cleaning water is intermittently pressurized and discharged by the check valve 61.
[0045]
In this embodiment, the discharge amount of the pump is changed by changing the voltage value supplied to the motor 55 as the water force changing means, and the water force ejected from the cleaning nozzle 2 is made variable. Here, since the control circuit 8 is configured to be capable of continuously changing the supply voltage to the motor 55, the water force can be continuously changed, so that it is possible to meet more detailed needs.
[0046]
FIG. 11 shows a graph of pump discharge pressure against time. By the action of the check valve 61, when the piston 59 moves forward, pressurized discharge (Pm) is performed, and when the piston 59 moves backward, water is absorbed into the cylinder 58. Since the intermittently pressurized discharge of the water supply means 1 is performed, the intermittently pressurized washing water is supplied to the washing nozzle 2, so that the jetting speed of the washing water can be further increased, and the same amount of water can be obtained with a smaller amount of water. A feeling of washing is obtained.
[0047]
FIG. 12 shows details of the fountain from the jet port 12 of the washing nozzle 2 due to the intermittent pressurized discharge of the water supply means 1 as shown in FIG. 11, and FIG. The change in the internal pressure of the nozzle with respect to the pressure indicates that the fountain is intermittently performed at the position where the water pressure is the maximum. The flow rate v of the fountain is increased by intermittent pressurized discharge of the wash water, and the water mass is deformed due to the air resistance in the process of jetting, and the water mass jetted at the diameter dn of the jet port 12 is washed. In the part 70, the diameter dw is larger than that. This makes it possible to realize a washing jet that gives a large bodily sensation despite a small amount of washing water, thereby improving the washing feeling.
[0048]
The discharge frequency range, that is, the discharge pressure fluctuation frequency is preferably set to a range suitable for the bodily sensation. The lower the ejection frequency is, the easier it is to perceive it, and the higher the ejection frequency is, the closer to a continuous flow. According to a bodily sensation experiment, the ejection frequency is in the range of 1 to 60 Hz, preferably 20 to 50 Hz. Since the same washing feeling as in the case of continuous water supply can be obtained with a smaller amount of washing water, it is convenient when the heating means 3 is of the instantaneous type as described above.
[0049]
In the present embodiment, a piston pump has been described as the water supply means 1, but any pump capable of intermittent pressurization and discharge may be used.
[0050]
FIG. 14 is a time chart showing the number of motor pulses, the number of pump revolutions, and the operation of the water supply valve 5 by the control circuit. First, when the number of motor pulses ST1 is given, the pulse motor, which is the drive unit 45 of the flow control means, rotates to stop the valve body 40 at the nozzle cleaning position (nozzle cleaning configuration is not shown), and the main valve 5 is opened. At the same time, the pump 1 serving as the water supply means operates to perform forced nozzle cleaning of the cleaning nozzle 2 from t1 to t2. Next, when the main valve 5 and the pump 1 are stopped for a predetermined time and the number of motor pulses is given to ST2, the valve body 40 is further rotated, and stopped at the position shown in FIG. 8A (t3). Water is passed. In this state, when the main valve 5 is opened and the pump 1 operates, the washing water is supplied into the nozzle cylinder 10, and the movable nozzle 11 advances by the water supply pressure against the spring force of the elastic member 24 and stops at the washing position. Then, the gas is ejected from the first passage 15 through the first passage 13 as the dispersed jet to which the rotational force is applied from the ejection hole 12 (t4). When the dispersed jet is selected by the user, the washing is continued in this state. On the other hand, when the concentrated jet is selected, the number of motor pulses is given up to ST3 and stopped at the position shown in FIG. 8C (t5), and the washing water flows from the second passage 16 to the second passage 14. After that, it is ejected from the ejection hole 12. At this time, since the cleaning water is not supplied from the first flow channel 13, the cleaning water is jetted as a concentrated jet having a strong cleaning sensation. The cleaning area can be continuously adjusted by adjusting the number of motor pulses from ST2 to ST3 from t4 to t5.
