Description

  The present invention relates to a warm water cleaning toilet seat that can comfortably clean a human body part.

  Conventionally, as this type of warm water cleaning toilet seat, for example, an ejector type nozzle has been used to increase the feeling of cleaning by mixing air into the cleaning water using the ejector effect (see Patent Document 1). In FIG. 6, the water nozzle 1 and the water nozzle 1 are substantially concentric and are composed of an aeration unit composed of a gas nozzle 2 having a diameter larger than that of the water nozzle 1 and a water discharge unit 3 having a flush water discharge port 4 connected to the gas nozzle 2. It had been.

  The flow rate of the washing water is increased by the water nozzle 1 in the aeration unit, and is ejected into the atmosphere. The washing water ejected into the atmosphere enters the gas nozzle 2 of the air mixing unit, a large amount of air is mixed, and is discharged from the water outlet 4 of the water discharging unit 3.

Further, by mixing a large amount of air into the cleaning water, the feeling of cleaning can be enhanced even with a small amount of cleaning water, and the temperature can be immediately increased with a household power source.

(Embodiment 1)
FIG. 1 is a partial cross-sectional side view showing a nozzle portion of a warm water cleaning toilet seat according to the first embodiment of the present invention.

  In FIG. 1, a nozzle device 11 has a jet hole 12 at its tip, and is configured to jet wash water to a local part of the human body. A flow rate adjusting valve 13 for adjusting the cleaning flow rate and a valve motor 14 for driving the same are provided at the rear end of the nozzle device 11, and water from a water supply unit (not shown) is guided to the internal flow path 15 of the nozzle device 11. ing.

  An ejector nozzle 16 is formed at the tip of the internal flow path 15, and an air mixing portion 18 having an air hole 17 a and an air hole 17 b on the lower surface is provided at the open end of the ejector nozzle 16. Inside the aeration unit 18, there is a vibrator 19, and a jet jet (not shown) from the ejector nozzle 16 reaches an introduction part 21 configured substantially concentrically through a through hole 20 provided in the vibrator 19. The structure communicates with the ejection hole 12.

  Further, the nozzle device 11 is inserted into the inclined groove 23 of the mount 22, and the rack gear 24 provided on the lower surface thereof is engaged with the drive motor 25a and the pinion gear 25b so that it can be driven in the axial direction along the inclined groove 23. It is configured. That is, the inclined groove 23 of the mount 22, the rack gear 24, the drive motor 25 a and the pinion gear 25 b constitute drive means for projecting and storing the nozzle device 11. It is possible to drive the ejection hole 12 of the nozzle device 11 from the standby position to the cleaning position by a control device 26 incorporating a microcomputer for outputting a signal.

  Further, by driving the drive motor 25a by the control device 26 so as to repeat normal rotation and reverse rotation in small increments, this drive means vibrates the nozzle device 11 in the axial direction at an arbitrary position from the standby position to the cleaning position. It constitutes vibration means. Along with the operation of the vibration means, the vibrator 19 can be vibrated inside the aeration unit 18.

  FIG. 2 is a cross-sectional view of a main part of the nozzle device of the warm water cleaning toilet seat according to the embodiment. FIG. 2A is a diagram illustrating a state in which the vibrator is located in front of the aeration unit, and FIG. 2B is a diagram illustrating a state in which the transducer is located behind the aeration unit.

  The vibrator 19 is provided with a second air hole 27 communicating with the outer periphery of the vibrator 19 and the through hole 20, and the vibrator 19 is positioned in front of the air mixing portion 18, as shown in FIG. When the second air hole 27 and the inner port 28a of the air hole 17a are in communication with each other, the vibrator 19 is located behind the aeration unit 18, and in FIG. The inner opening 28b of the air hole 17b communicates, and the vibrator 19 closes the air hole 17a and the air hole 17b when the vibrator 19 moves in the middle of FIG. 2 (a) and FIG. 2 (b). It has become.

  In this configuration, when the vibration means is not operating, the vibrator 19 is located in front of the aeration unit 18 due to gravity, and is in communication with the engulfing action of a jet jet (not shown) from the ejector nozzle 16. Air is continuously mixed from the holes 17a. On the other hand, when the vibration means is operating, the vibrator 19 vibrates between the front position, FIG. 2A and the rear position, and FIG. The hole 17 b is intermittently opened and closed, and air is intermittently mixed into the air mixing portion 18.

  FIG. 3 is a nozzle vibration pattern diagram and a cleaning water flow shape diagram of the hot water cleaning toilet seat according to the embodiment. 3A is a nozzle vibration pattern diagram and a cleaning water flow shape diagram when the operation of the drive motor 25a is controlled by the control device 26 and the vibration amplitude is small, and FIG. 3B is a diagram when the vibration amplitude is large. It is a nozzle vibration pattern figure and a washing water flow shape figure.

  By increasing the vibration amplitude, the fluctuation width of the water flow center position is increased, the moving speed of the vibrator 19 is fast, the time for closing the second air hole 27 is shortened, and the amount of air mixing is increased. The washing water flow diameter is also increased. By changing the amplitude of vibration by the control device 26, the area to be cleaned can be varied.

(Embodiment 2)
FIG. 4 is a nozzle vibration pattern diagram and a cleaning water flow shape diagram of the warm water cleaning toilet seat according to the second embodiment of the present invention. 4A is a nozzle vibration pattern diagram and a cleaning water flow shape diagram when the operation of the drive motor 25a is controlled by the control device 26 and the period of vibration is large, and FIG. 4B is a diagram when the period of vibration is small. It is a nozzle vibration pattern figure and a washing water flow shape figure.

  As the vibration cycle becomes smaller, the fluctuation width at the center of the water flow does not change, but the moving speed of the vibrator 19 increases and the time during which the second air hole 27 is closed is shortened. As a result, the amount of air mixed in increases and the cleaning water flow diameter increases, and the foaming feeling of cleaning increases and becomes mild. By changing the vibration period by the control device 26, the feeling of cleaning can be changed.

(Embodiment 3)
FIG. 4 is a nozzle vibration pattern diagram and a cleaning water flow shape diagram of the warm water cleaning toilet seat according to the third embodiment of the present invention. FIG. 4A is a nozzle vibration pattern diagram and a cleaning water flow shape diagram when the operation of the drive motor 25a is controlled by the control device 26 and the forward speed of vibration is small and the return speed is large. FIG. FIG. 6 is a nozzle vibration pattern diagram and a washing water flow shape diagram when the forward speed of vibration is large and the return speed is small.

  When the moving speed of the vibrator 19 is fast, the amount of air mixing is increased by shortening the time during which the second air hole 27 is closed. On the other hand, when the moving speed of the vibrator 19 is slow, the second air hole The amount of air mixing is reduced by increasing the time during which 27 is closed. As a result, the symmetry of the shape of the washing water flow is lost, and the control device 26 changes the forward speed and the return speed of the vibration, and by repeating FIG. 5 (a) and FIG. 5 (b) alternately, it is extremely massaged. Highly effective cleaning can be realized.

  In the present embodiment, air is continuously mixed when the vibration means is not operating. However, the vibration means is adjusted by adjusting the positional relationship between the air holes 17 and the second air holes 27. Even in a configuration in which air is not mixed when not operating and is intermittently mixed during a vibration operation, the same effect of varying the feeling of cleaning can be obtained.

  As described above, the present invention is useful as a warm water cleaning toilet seat that can comfortably clean a human body part.
