  Hereinafter, the present invention will be described in more detail with reference to the drawings. Fig.1 (a) is a perspective view of the Western-style toilet equipment provided with the hand-washing apparatus based on Embodiment, FIG.1 (b) is a longitudinal cross-sectional view of a tank cover upper part.

  A tank cover 2 is installed on the upper surface of the rear part of the porcelain western-style toilet 1, and a top cover 3 having a bowl 10 is installed on the upper part of the tank cover 2. A toilet seat 4 and a toilet lid 5 are attached to the front portion of the tank cover 2 so as to be rotatable in the vertical direction.

  In the tank cover 2, in addition to a low tank 7 for supplying water to the toilet bowl of the Western-style toilet 1, a warm water washing nozzle 8 for washing the buttocks of a person sitting on the toilet seat 4 with warm water, and other various devices Is installed. The row tank 7 is provided with a ball tap (not shown), and tap water can be supplied into the row tank 7 through the ball tap.

  A currant part 11 is erected from the upper part of the rear edge of the top cover 3 so as to protrude onto the bowl 10 of the top cover 3, and a spout 12 is provided on the lower surface of the front end side of the currant part 11. The water outlet 12 is connected to a ball tap (not shown) of the low tank 7 through a water supply tube 13. A sensor 14 is provided on the lower surface of the currant portion 11 to detect the hand that has been put into the bowl 10. The sensor 14 is a distance measuring infrared sensor that detects the distance to the hand, and can determine whether the hand has been extended to the upper region or the lower region with respect to the overflow port 20.

  A drain port 15 is provided at the bottom of the bowl 10, and a pop-up drain plug 16 is provided. The drain plug 16 is connected to the operating rod of the solenoid 17 via a link 18 and moves up and down by the stroke of the operating rod of the solenoid 17 to open and close the drain port 15. Below the drainage port 15 is a drainage cylinder 19 extending downward in a cylindrical shape, and this drainage cylinder 19 is arranged to drop water into the raw tank 7.

  An overflow port 20 is provided on the side surface of the bowl 10, and is configured to guide the overflow water to the drain tube 19 through the drain channel 21.

  A diffuser plate 22 is provided on the bottom surface of the bowl 10. Air is supplied to the diffuser plate 22 from the air pump 24 via the hose 23. The air pump 24 is disposed above the overflow port 20.

  In the Western-style toilet facility having the hand-washing apparatus configured as described above, the water in the low tank 7 flows out into the toilet bowl of the Western-style toilet by performing a remote control operation or a flash lever operation. As the water level in the low tank 7 decreases, a ball tap (not shown) provided in the low tank 7 opens, and water is injected into the low tank 7. Further, water is supplied to the water outlet 12 through the water supply tube 13 as the ball tap is opened, and water is discharged from the water outlet 12 into the pot 10. The toilet user can put his hands in the bowl 10 and wash his hands. When the water level in the low tank 7 reaches the specified water level, the ball tap is closed and water discharge from the water discharge port 12 is also stopped.

  In this embodiment, when a hand is put out above the overflow port 20 in the bowl 10, the drain plug 16 is left in an open state in which the water is discharged, and the discharged water is discharged from the drain port 15 to the drain tube. It immediately flows out to the low tank 7 through 19. When a hand is inserted below the overflow port 20, the solenoid 17 is moved backward by the signal from the sensor 14, and the drain plug 16 is pulled down to be closed. Therefore, water discharged from the water outlet 12 is stored in the bowl 10. In addition, after the drain plug 16 is closed, preferably after a period of time in which water accumulates in the pot 10 to some extent, the air pump 24 is activated and air is ejected from the diffuser plate 22 as bubbles. For this reason, a hand can be immersed in the stored water in the pot 10 and the hands can be sufficiently washed with bubbles. In this case, even if both hands are not rubbed together, for example, even when one hand is immersed in water, the hand can be sufficiently washed.

  Even if the water level in the basin 10 reaches the overflow port 20, if water is discharged from the water discharge port 12, the overflow water flows out to the low tank 7 through the overflow port 20, the drainage channel 21, and the drain tube 19.

  When the sensor 14 detects that the hand has been detached from the pot 10, the solenoid 17 is operated to project the rod, the drain plug 16 is opened, and the stored water in the pot 10 flows out to the raw tank 7.

  Thus, according to this embodiment, water can be stored in the pot 10 and the hands can be sufficiently washed. Moreover, since the water level in the bowl 10 is set to the overflow port 20 or less, it does not overflow from the upper edge of the bowl 10. Both waste water and overflow water from the bowl 10 are collected in the low tank 7 and used for toilet cleaning.

  In this embodiment, air is diffused from the diffuser plate 22 to assist hand washing, but the stored water may be swirled using a rotating member or a water jetting member. Further, water may be vibrated by an ultrasonic oscillator.

  In the above-described embodiment, the drain plug 16 is configured to close when a hand is inserted below the overflow port 20, but is the upper side above the overflow port 20 when a hand is inserted below the spout 12? The drain plug 16 may be configured to be closed regardless of the lower side. In this case as well, the hand washing assisting means may be activated when the drain plug 16 is closed.
