BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to hygienic equipment, and more particularly to a hygienic apparatus that includes a urinal and a toilet bowl.
2. Description of the Related Art
A toilet bowl typically includes a seat disposed pivotally on a bowl body and pivotable between a horizontal usable position and an upright idle position. When the seat is pivoted to the upright position, the toilet bowl can serve as a male urinal.
With such a configuration, pivoting movement of the seat between the horizontal usable position and the upright position may be required prior to use. Furthermore, due to the limited height of the toilet bowl, during use of the toilet bowl as a male urinal, the seat as well as the bowl body and a floor area surrounding the bowl body may be stained by urine. To solve this problem, a male urinal can be provided in proximity to and spaced apart from the toilet bowl. However, the provision of a male urinal and a toilet bowl as separate devices results in a substantial indoor space being used.
SUMMARY OF THE INVENTION
The object of this invention is to provide a hygienic apparatus that includes a toilet bowl and a urinal and that can overcome the above-mentioned disadvantages associated with the prior art.
According to this invention, a hygienic apparatus includes a urinal, a toilet bowl, and a water-storing device including a housing body interconnecting the urinal and the toilet bowl, a water tank disposed in the housing body, and a water-feeding tube allowing flow of water into the water tank therethrough. A drain tube unit is in fluid communication with the urinal and the toilet bowl. A flush unit includes a urinal-flushing tube in fluid communication with the water tank and the urinal, and a toilet-flushing tube in fluid communication with the water tank and the toilet bowl. A swivel mechanism includes a base, a vertical shaft disposed fixedly on the base and extending into an assembly of the urinal, the toilet bowl, and the water-storing device, and a driving unit operable to drive rotation of the assembly of the urinal, the toilet bowl, and the water-storing device relative to the base about the vertical shaft.
Preferably, a wall is formed with a cavity, and the urinal can be rotated into the cavity when it is not in use. As a result, the indoor space occupied by the hygienic apparatus and exposed outwardly of the wall is reduced significantly.

The driving unit 422 includes a pair of first and second gears 425, 426 disposed in the recess 21 in the toilet bowl 2, and a motor 423 disposed in the toilet bowl 2. The first gear 425 is sleeved fixedly and coaxially on the vertical shaft 421. The second gear 426 is disposed in the toilet bowl 2, is connected fixedly to an output shaft 427 of the motor 423, and meshes with the first gear 425. The second gear 426 can be driven by the motor 423 to rotate on and about the first gear 425 to thereby drive rotation of an assembly of the urinal 1, the toilet bowl 2, and the water-storing device 3 relative to the base 41 about the vertical shaft 421. As such, the urinal 1 is rotatable between a concealed position shown in FIG. 5 whereat the urinal 1 is concealed within a cavity 81 in a wall 8 of the bathroom, and an exposed position in FIG. 6 whereat the urinal 1 is exposed outwardly of the wall 8. The upper and lower ball bearings 424, 424′ abut respectively against top and bottom ends of the first gear 425, and are disposed around the vertical shaft 421. The upper bearing 424 is received within the pivot hole 22 in the toilet bowl 2 in a close-fitting manner. The lower bearing 424′ is disposed in the recess 21 in the toilet bowl 2 and between the toilet bowl 2 and the base 41.
The control unit 44 includes a circuit board module 441 disposed in the toilet bowl 2, and a pair of first and second control buttons 442, 443 in electrical connection with the circuit board module 441. The circuit board module 441 is in electrical connection with the motor 423 and a power cable 43 (see FIGS. 3 and 4) extending through the vertical shaft 421 and in electrical connection with an external power source (not shown). The first and second control buttons 442, 443 are disposed on a wall of the bathroom, and are operable to rotate the output shaft 427 of the motor 423 in two directions, respectively, as shown in FIGS. 5 and 6. When the urinal 1 is in the concealed position and when the first control button 442 is pressed, the urinal 1 is rotated in a direction to the exposed position. Subsequently, when the second control button 443 is pressed, the urinal 1 is rotated in an opposite direction to thereby return to the concealed position.
Alternatively, an assembly of the motor 423, the control unit 44, and the power cable 43 may be replaced with a manual operation unit.
The position-limiting unit 5 includes a pair of first and second position-limiting members 51, 52 disposed on and respectively adjacent to two opposite sides of the base 41 and flanking the vertical shaft 421, and a third position-limiting member 53 disposed in the recess 21 in the toilet bowl 2. The third position-limiting member 53 is rotatable on the base 41 to align with either of the first and second position-limiting members 51, 52, as shown in FIGS. 3 and 4, to thereby stop operation of the driving unit 422. Thus, rotation of the assembly of the urinal 1, the toilet bowl 2, and the water-storing device 3 about the vertical shaft 421 is limited within an angle of 180°.
In this embodiment, the first and second position-limiting members 51, 52 are configured as micro-switches, and are in electrical connection with the circuit board module 441. The third position-limiting member 53 is rotatable to contact either of the first and second position-limiting members 51, 52. Alternatively, the first and second position-limiting members 51, 52 may be configured as projections for stopping the third position-limiting member 53 when the third position-limiting member 53 comes into contact therewith. In addition, the motor 423 may be a stepping motor, in which case the position-limiting unit 5 can be omitted. Further, either the first gear 425 or the second gear 426 may be formed with gear teeth extending along an angular length of 180 degrees to limit the rotational angle of the assembly of the urinal 1, the toilet bowl 2, and the water-storing device 3.
The first and second gears 425, 426 may be replaced with a transmission belt unit. The motor 423 can be a D.C. frequency change motor.
FIGS. 8 and 9 show a modified driving unit that is similar in construction to the driving unit 422. In this embodiment, the first gear 425′ is configured as an internal gear to allow rotation of the second gear 426 therewithin, and the motor 423 and the circuit board module 441 are disposed in the base 41.
Referring to FIG. 10, the base 41 can be embedded within a floor 9, and the first and second control buttons 442, 443 may be disposed on the housing body 31 of the water-storing device 3.
With this invention thus explained, it is apparent that numerous modifications and variations can be made without departing from the scope and spirit of this invention. It is therefore intended that this invention be limited only as indicated by the appended claims.
