  • the present invention relates to a sanitary cleaning apparatus for cleaning the private parts after stool and more particularly to a sanitary cleaning apparatus which effectively cleans the private parts by changing the flow state of cleaning water and allows a user to select a desired pattern of cleaning jet flow.
  • one nozzle or a plurality of nozzles are used to jet hot water to the private parts.
  • the cleaning water jetted from the nozzle or nozzles are in the form of convergent steady flow. Therefore, a user feels uncomfortable when the cleaning water collides with the private parts.
  • the apparatus is intended to generate a jet flow which gives a soft feeling to a user by bubbles contained in the cleaning water.
  • the apparatus comprises an ejector nozzle, disposed in the vicinity of a jet opening of a nozzle, for increasing the flow speed of the cleaning water; and an air sucking portion for sucking air from a negative pressure space generated by a high-speed flow of the cleaning water jetted from the nozzle and containing air in the cleaning water. That is, the apparatus is intended to give a soft feeling to the user by the cleaning water containing air jetted from the jet opening during cleaning operation. But the cleaning water does not fluctuate in its flow over the region to be cleaned.
  • the cleaning efficiency has yet to be improved.
  • Excrement attached to the region to be cleaned is washed away therefrom by the process in which the cleaning water penetrates into a portion between the region to be cleaned and the excrement, thus reducing the connection therebetween and the process in which the cleaning water collides with the region to be cleaned, thus separating the excrement from the region to be cleaned.
  • the excrement can be effectively separated from the region to be cleaned by moving jet flows on the region to be cleaned fluctuantly and widely.
  • the sanitary cleaning apparatus used by the above apparatus contains air therein, it is convergent jet flow and thus it is impossible to clean the region to be cleaned widely in conformity to the configuration of the region to be cleaned.
  • the construction of the apparatus necessitates the movement of the entire nozzle device in order to clean the region to be cleaned efficiently and widely.
  • a particular driving means is essential and thus the apparatus is complicated in construction and large, which leads to a high cost.

  • the sanitary cleaning apparatus is intended to generate a stable oscillation by utilizing the pressure difference between the two swirl chambers disposed on both sides of the direction of the jet flow. Therefore, in a low flow rate region, the flow speed of the cleaning water jetted from the contraction portion 8 is reduced and hence it is difficult to obtain the pressure difference reliably. In addition, a slight change in sizes of constituent members or in the supply state of the cleaning water cause bubbles to be contained in the cleaning water at a nonuniform ratio. Hence, oscillation becomes unstable in the low flow rate region.
  • the sanitary cleaning apparatus is utilized by a plurality of persons and thus favorable states of a jet flow are different from each other according to sex, age, seating position or the like. Therefore, there is a growing demand for the development of a sanitary cleaning apparatus allowing a user to select a pattern of jet flow in accordance with the user's desire. As a measure for complying with such a demand, a sanitary cleaning apparatus allowing a user to select the flow speed of the cleaning water to a favorable speed from among a plurality of flow speeds but the pattern of the jet flow is the same in each flow speed. Hence, the sanitary cleaning apparatus has yet to be improved.

Then, the water in the tank 30 is jetted from any one of the cleaning nozzles 17, 18, and 19.
  • a desirable jet pattern can be selected by selecting any one of the first, second, and third switches 21, 22, and 23, and in addition, a desired flow speed of the cleaning water can be selected by adjusting the flow speed adjusting switch 25 which controls the pump 27.
  • JP-A-2-80725 Patent Abstracts of Japan Vol.14, no.271 (M-983)(4214) defining the closest prior art from which the invention proceeds discloses a washer for private part.
  • the known washer has a plurality of nozzles, the axes of which are constituted so as to be crossed as an intersection near the anus of a human body and a bidet respectively, wherein the wash water is injected so as to be concentrated at one point near the anus of a human body and a bidet respectively. Anus washing and bidet washing are conducted by separate nozzles.
  • US-A-4 761 837 discloses a washing device for parts of a human body comprising a pump means to supply water from a water source under pressure and a nozzle means which spouts the pressurized water against the private parts of the human body as a water jet. Since the pump means has an air intake port on the suction side, air foam is securely mixed in the water jet. Also, since an air control valve is provided in connection with the air intake port, the mixing ratio of the air in the water can be controlled by the air control valve.
  • the sanitary cleaning apparatus has a complicated construction and is large and hence expensive.
  • a sanitary cleaning apparatus comprising a cleaning water supply means, a water supply channel, and a cleaning nozzle for jetting cleaning water toward a region (A) to be cleaned, said cleaning nozzle comprising a nozzle chamber communicating with said water supply channel and a plurality of jetting openings communicating with the nozzle chamber, wherein the axes of the jet flows discharged from said jetting openings intersect with each other, characterized by a turbulence generating means for making jet flows discharged from said jetting openings turbulent, said turbulence generating means comprising an air mixing means for mixing air in the cleaning water, and a jet flow selection means for selecting presence or absence of air mixing into the cleaning water by controlling said air mixing means, whereby dispersed jet flows and concentrated jet flows can be selectively discharged by the selective actuation of said jet flow selection means, wherein the axes of the jet flows discharged from said jetting openings intersect with each other between a jetting surface of said cleaning
  • the cleaning nozzle comprises a plurality of jetting opening capable of jetting cleaning water supplied from the cleaning water supply means.
  • the jetting openings are inclined so that a part of axes thereof or all axes thereof which jet cleaning water intersect with each other between a jetting surface of the cleaning nozzle and the region to be cleaned.
  • Turbulence generating means is provided to generate turbulence in the cleaning water to be discharged the jetting openings. Further, inside the nozzle, the turbulence generating means generates bubbles in the cleaning water to change the pressure of fluid and thereby change the flow speeds of jet flows discharged from the jetting openings.
  • the turbulence generating means serves as a means for altering the rate flow jetted from each jetting opening and further, containing air in the cleaning water so as to generate turbulence in jet flows.
  • the cleaning water supplied from the cleaning water supply means is jetted from the jetting openings, the jet flows intersect with each other between the jetting surface of the cleaning nozzle and the region to be cleaned. As a result, the jet flows become confluent with each other. Resolving the forces of respective jet flows at the confluent point into horizontal components and vertical components of the jet direction, the forces of the vertical components of respective jet flows are jetted in different flow states due to a jet speed, a flow rate, and the dissolution of air in the cleaning water.
  • the vertical components of respective jet flows are unbalanced with each other and hence, the jet flows fluctuate.
  • the inclination of the jetting openings and the provision of the turbulence generating means cause jet flows to fluctuate, thus separating excrement from the region to be cleaned efficiently and cleaning the region to be cleaned widely.
  • the range of the jet flow to be applied to the region to be cleaned, namely, a cleaning position can be easily adjusted by selecting the inclination of the jetting openings. Because jet flows are fluctuated by making them turbulent in order to change the vertical components of the forces of the jet flows in different flow states, a slight change in dimension and in the supply state of the cleaning water do not affect the fluctuant state of the cleaning water even in a low flow rate.
  • a sanitary cleaning apparatus comprising: a cleaning water supply means; a water supply channel; a nozzle comprising a plurality of jetting openings inclined by a predetermined angle and jetting the cleaning water toward the region to be cleaned so that a part of axes of the jetting openings or all axes thereof intersect with each other between a jetting surface of the cleaning nozzle and the region to be cleaned; air containing means for containing air in the cleaning water; air dissolution selection switch for selecting or rejecting the dissolution of air in the cleaning water; and air amount adjusting means for controlling the air containing means based on a signal outputted from the air dissolution selection switch.
  • a user is allowed to select a desirable cleaning pattern from among a steady convergent jet flow and a dispersive jet flow to be applied to the region to be cleaned in a wider range than the steady convergent jet flow by selecting the air dissolution selection switch. That is, supposing that air is not contained in the cleaning water, when the cleaning water which has been supplied from the cleaning water supply means is jetted from the jetting openings, jet flows intersect with each other between the jetting surface of the nozzle and the region to be cleaned. As a result, the jet flows are in contact and confluent with each other at the intersection. Resolving the forces of respective jet flows at the confluent point into horizontal components and vertical components of the jet direction, the vertical components are balanced with each other.
  • the cleaning water is jetted toward the region to be cleaned in the form of a steady convergent flow.
  • jet flows discharged from the jetting openings are different from each other in flow state and thus the vertical components of respective jet flows are unbalanced with each other and hence, the jet flows fluctuate.
  • the control over the mixture of air with the cleaning water allows the user to select the desirable cleaning pattern from among the steady convergent jet flow and the dispersive jet flow to be applied to the region to be cleaned in a wider range than the steady convergent jet flow. Accordingly, the user can select a desirable jet flow from among the above two kinds of jet flows without using a dedicated nozzle or a switching means.
  • air can be contained in the cleaning water in a wide range. That is, air can be contained in the cleaning water anywhere in the supply system of the cleaning water and thus, a remote control can be performed easily in selecting a desired jet flow.
  • the present invention provides a cleaning pattern in which a convergent cleaning and a wide range cleaning alternate with each other. Therefore, the flow speed of the cleaning water fluctuates, and the cleaning water is jetted to the region to be cleaned convergently and dispersively, which washes excretion away from the anal region reliably. Thus, the anal region can be cleaned efficiently. Further, this way of cleaning does not give the feeling of monotonousness to the user.
  • a sanitary cleaning apparatus comprises a first duct and a second duct; a plurality of jetting openings communicating with each of the first duct and the second duct; and flow amount ratio adjusting means for controlling the distribution ratio of the amount of the cleaning water to be supplied to the first duct and the second duct.
  • the axes of the first duct and that of the second duct intersect with each other between a jetting surface of the cleaning nozzle and a region to be cleaned.
  • the user can be allowed to select a desirable cleaning pattern from among the steady convergent jet flow and the dispersive jet flow to be applied to the region to be cleaned in a wider range than the steady convergent jet flow by controlling the distribution ratio. That is, if the ratio of the flow amount to be jetted from the first jetting opening to the flow amount to be jetted from the second jetting opening is controlled to be 1:1, jet flows intersect with each other at a predetermined position and become confluent with each other. Resolving the forces of respective jet flows at the confluent point into horizontal components and vertical components of the jet direction, the vertical components are balanced with each other. In this manner, the cleaning water is jetted toward the region to be cleaned in the form of a steady convergent flow.
  • the ratio of the flow amount to be jetted from the second jetting opening is set to be more than the flow amount to be jetted from the first jetting opening, the vertical components are unbalanced with each other.
  • the jet force from the second jetting opening increases while the jet force from the first jetting opening decreases. Consequently, jet flows which have been confluent with each other are jetted toward the region to be cleaned on the first jetting opening side. That is, it is possible to change the cleaning position by altering the distribution ratio of the cleaning water to be supplied to the first and second jetting openings.
  • the user can be allowed to select a desirable cleaning pattern from among the steady convergent jet flow and the dispersive jet flow to be applied to the region to be cleaned in a wider range than the steady convergent jet flow by merely controlling the distribution ratio. Furthermore, because the direction of the jet flow can be changed without moving the nozzle, excrement can be separated from the region to be cleaned with a high efficiency and the cleaning apparatus has a simple construction. In addition, the user can change the direction of the jet flow as desired by controlling stepwise the distribution ratio of the cleaning water. That is, the cleaning position can be adjusted without moving the nozzle.

  • the cleaning water containing air is jetted from the jetting openings 45a and 45b. Jet flows of the cleaning water become confluent in contact with each other at the point (P). At this time, the jet flows of the cleaning water are in different flow states because air is dissolved in the cleaning water by the turbulence generating means 47. Resolving the force of each jet flow at the confluent point (P) into a horizontal component and a vertical component, the forces of the vertical components of respective jet flows become unbalanced and the directions and forces of respective jet flows become differentiated from each other and thus the entire cleaning water fluctuates. Referring to Fig.
