, in lieu of using a single valve
25
to control the hot and the cold fresh waters as shown in
FIG. 3
, two valves
79
and
80
,
FIG. 8
, can be used to control the cold fresh water and the hot fresh water, respectively. Similarly, two valves
81
and
82
,
FIG. 8
, can be used to control the cold recycled water and the hot recycled water, respectively, instead of using one single valve
41
as shown in FIG.
3
.
The common water supply system consists of up pipe
46
and a down pipe
47
. The up pipe is a pipe which one end connects with the shower arm and which the other end connects with the mixed recycled water piping and the mixed fresh water piping. The down pipe is also a pipe which one end connects with the spout and which the other end connects with the mixed recycled water piping and the mixed fresh water piping.
Referring to
FIG. 5
, the invented shower stall that has a pump
48
is very similar to the invented bath and shower stall that has a pump described above. The major differences between these two variations of the invented devices are that the invented shower stall that has a pump does not have the bathtub, the spout and its associated down pipe.
Referring to
FIG. 1
, in using the invented bath and shower stall that has a pump, the user plugs the tub sink
19
first with the tub drain plug
20
. Then, the user turns on the faucets to let fresh water into the bathtub. Water enters the bathtub will drain through the drain
34
and the pipe
35
(referring to
FIGS. 1
,
2
and
4
) then enters into the water storage tank
31
. When the water storage tank is about full or water can not be drained from the bathtub any more, the user turns off the fresh water. The user then turns on the power on toggle switch
49
(
FIG. 1
) which turns the motor and the pump on. The user then turns on the faucet(s) of the recycled water supply system. Water will then come out from either the spout or the shower head. The discharged water can drain back into the drain
34
then into the water storage tank. The water then can be recycled by the pump and pumped through the shower head or the spout. The start of flowing of the recycled water through the water heater will turn on the water heater.
When the user selects to let water be discharged through the shower head, the user can take a shower as long as desired without wasting fresh water. The user can operate the faucet(s) of the recycled water supply system to control the ratio of recycled water between passing through the water heater and the water heater bypass pipe so that the temperature of the recycled water discharged from the shower head can be selected and controlled.
After having the pleasure of a long shower, the user can turn off the faucet(s) of the recycled water supply system. The stop of the recycled water will turn off the water heater. The stop of the recycled water will cause the pump to pump against high hydraulic pressure and after a while will activate the pressure and timer switch to shut off the pump. The user can unplug the tub sink
19
and plug the drain
34
by moving the tub drain plug
20
from the tub sink
19
to the drain
34
. The user then can take a regular fresh water shower to complete his/her shower.
In lieu of turning off the faucet(s) of the recycled water supply system to stop the recycled water, the user may unplug the tub sink
19
and plug the drain
34
first to stop the recycled water. To plug the drain will cause the recycled water not being able to enter the water storage tank. When the pump continuously sucks out the water in the water storage tank, the water level in the water storage tank will continuously drop. Eventually, when the water level is low enough the water level switch in the water storage system will shut off the pump. The unplugged tub sink will drain the recycled water discharged from the shower head or the faucet. Thus, the recycled water system can be drained if needed.
Although the foregoing descriptions of the uses of the invented devices concentrate on the invented bath and shower stalls that have pumps, the uses of the invented shower stalls that have pumps are very similar to those described. Therefore, the uses of the invented shower stall that has a pump are not described herein.
The foregoing is considered as illustrative only of the principles of the invention. Furthermore, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents, may be resorted to, failing within the scope of the invention as claimed.
