Definitions
- the illustrated mechanism includes a "pulsing circuit board” which provides two functions, namely it senses low batteries and turns on a warning light before the batteries become too low to operate the flush mechanism. In addition, it turns the pump drive motor on and off to provide the required pulsed flushing action.
- the "pulsing circuit board” is operated to turn the motor off and on at predetermined time intervals, such as every second, so as to obtain a "pulsed flush". This type of flush is desirable in that it provides both high velocity water and low velocity water on the flush ledge of the toilet bowl to provide in turn for a uniform wetting of the bowl by the flush water.
- the improved flush apparatus as illustrated includes an axial flow plump which employs a rotatable propeller which includes a plurality of short spiral vanes.
- a rotatable propeller which includes a plurality of short spiral vanes.
- the vanes push the water upwardly into a spiral cavity within the pump housing which in turn directs the flush water into a tube which lifts the water about 30 cms (12") into the top of the toilet bowl.
- the pump structure is advantageous in that it provides maximum efficiency in terms of use of battery current to lift relatively small amounts of water relatively short distances and pulse it into a toilet bowl. This arrangement provides for prolonged service life of the flush batteries and in addition minimises the need for frequent refilling of the toilet flush water tank.
- a pumping mechanism indicated generally at 26 is provided for pumping fresh water from the water storage chamber 22 into the bowl 16 in order to flush the toilet.
- the bowl 16 includes a bottom discharge opening 28 at its lower end and a flush ledge 30 near its upper end on which flush water is deposited for flow along the ledge and inwardly off the ledge so as to uniformly wet the bowl 16.
- the discharge opening 28 registers with an inlet opening 32 ( Figure 3) in the top wall of holding tank 14. Opening 32 is closed by a slide valve 34 mounted within the interior of the holding tank 14. Because of the separable mounting of the two sections 12 and 14, the holding tank section 14 can be removed for dumping.
- the lower end of the actuator cap skirt 70 is formed at a plurality of circumferentially spaced points with inwardly directed projections 72 which, when the cap 66 is manually telescoped downwardly over the housing 42, will snap over a corresponding number of outwardly extending projections 74 formed on the housing 42.
- the cap 66 is formed of a relatively thin gauge deflectable plastic material so that the skirt 70 will readily deflect outwardly and spring back inwardly as the projections 72 pass over the projections 74.
- the skirt 70 can be manually grasped and squeezed to deflect the lower end of the skirt 70 outwardly so as to enable the projections 72 to pass over the projections 74 when it is desired to remove the actuator cap 66 from the housing 42.
- the low battery indicator circuit 151 includes a voltage detector 154 which is powered by battery voltage flowing through a diode 156.
- the voltage detector 154 provides a constant voltage output at the terminal 158 while the battery voltage is within a given range. If however, battery voltage falls below a predetermined level, the terminal 158 is turned off. The signal from terminal 158 is applied to the base terminal of the transistor 160.
- the emitter of the transistor 160 is at battery voltage once the switch 96 is closed.
- the low battery warning LED 92 is connected between battery ground and the collector of the transistor 160.
- this invention provides a portable toilet 10 which includes a battery operated flush assembly. Furthermore, the battery operated flush assembly provides for a "pulsed" action of the flush water in the toilet bowl 16 to provide for more efficient and improved flushing action. This is accomplished by using the improved axial flow pump which operates to lift relatively small amounts of water relatively short distances and pulse it into the toilet bowl. All of these advantages are obtained while still maintaining efficient use of the batteries that operate the flush mechanism and without risking leaking of the flush water from the toilet during transport.
