As shown in side view of
As shown in exploded perspective view of
In an operating method of the control unit 40, if a user pushes the button 41, the first pushers 432 inserted into the receptacles 423 push an upper surface of the second link member 45 located therebelow, and simultaneously, the second pusher 433 between the first pushers 423 pushes an upper surface of the first link member 44. Thereby, the first and second link members 44 and 45 are rotated about their insertion bores 44a and 45a inserted around the supporting rods 421a and 422a. In this case, a distal end of the upper surface of the first link member 44 pushes an upper end of the insertion bore 45a of the second link member 45, thus causing the connecting chain 49, connected to an end of the second link member 45 to be pulled up. Also, as one end of the first link member 44 is lifted by the second pusher 433, the connecting bar 46, in which the other end of the first link member 44 is inserted, is moved upward, thus allowing the third link member 48, which is also coupled to the connecting chain 49, to be lifted simultaneously with the pushing operation of the pushing lever 43. As a result, the connecting chain 49 is pulled up by both the second and third link members 45 and 48 connected thereto, so as to control opening and closing of the water discharge unit 30 that is coupled to a lower end of the connecting chain 49.
Referring to
FIGS. 7 to 9 illustrate an exemplary embodiment of the auxiliary water tank device in accordance with the present invention. More particularly,
First, if the wash water, stored in the housing 10, is discharged through the water discharge port 12, the float barrier 29 and the screw rod 28 of the water supply unit 20 are slowly lowered, such that the water supply pipe opening/closing member 26 opens the through-hole 242 of the water supply pipe cap 24, to enable the supply of wash water. After a predetermined amount (for example, approximately 2.3 liters) of wash water is supplied, the float barrier 29 and the screw rod 28 are slowly lifted, such that the water supply pipe opening/closing member 26 closes the through-hole 242 of the water supply pipe cap 24, to interrupt the supply of wash water. In this case, the regulator plug 23, which is mounted in the water supply pipe 21 on the top of the water supply nozzle 22, moves up to open the water supply nozzle 22 when the wash water is supplied into the water supply pipe 21, and again returns to its original position to close the water supply nozzle 22 if the supply of wash water is interrupted.
If the user pushes the button 41 on the water tank cover 722, the pushing lever 43 is pushed as shown in
