Except that the washing cycle needs to be added with detergent or washing chemicals, each rinsing cycle use water to remove the detergent or washing chemicals added in the washing cycle. Each rinsing cycle consumes a lot of time for waiting the laundry basket of the machine to be filled up with water. Also, the water used in each rinsing cycle is discharged out. In fact, the water used in the last one or two rinsing cycles is often clean enough to be used again, because the clothes would be taken to a dryer machine after the final rinse and then can be directly put on a person. At least, the water used in the final rinsing cycle would be clean, it is unfortunate that the existing washing machines do not make use of the rinse water again.

FIGS. 1 and 3 respectively show a schematic view and a diagram of one embodiment of the present invention, which illustrate how a washing machine of the present invention can save time and power in a laundry activity. As shown, thewashing machine 11 generally comprises water storage means 1, awater inlet 2, a connection pipe assembly including anupstream pipe 4 and adownstream pipe 6, apipe control valve 5, acontroller 7, a three-way control valve 8, a reclaimingpipe 9, anoverflow pipe 10, alaundry basket 11 a, and adischarge pipe 12. Although the embodiment shows only one laundry basket therein, the present invention can have more than one laundry basket as well. Thewater inlet 2 is adapted to be connected to an outside fresh water source, such as a tap water supply. The water storage means 1, which may include one water tank, is provided with at least onewater level regulator 3, at an end of thewater inlet 2, which can close or open thewater inlet 2 according to water level of the water storage means 1. Thewater level regulator 3 can be a traditional ball float device. When water level of the water storage means 1 is higher than a predetermined level, thewater level regulator 3 can close thewater inlet 2 to stop water from entering the water storage means 1. When water level of the water storage means 1 is lower than the predetermined level, thewater level regulator 3 can open thewater inlet 2 to allow water to enter the water storage means 1. The connection pipe assembly, which includes at least oneupstream pipe 4 and at least onedownstream pipe 6, is connected between the water storage means 1 and thelaundry basket 11 a. Thepipe control valve 5, which is provided for the connection pipe assembly, is mounted between theupstream pipe 4 and thedownstream pipe 6 thereof, so that theupstream pipe 4 is connected between the water storage means 1 and thepipe control valve 5, and thedownstream pipe 6 is connected between thepipe control valve 5 and thelaundry basket 11 a. Generally, the pipes of the connection pipe assembly have a diameter greater than thewater inlet 2. Alternatively, the connection pipe assembly can be designed to be in combination of large-diameter pipes and small-diameter pipes. Fore examples, some pipes of the connection pipe assembly may have a diameter greater than thewater inlet 2, while some other pipes of the connection pipe assembly may have a diameter less than thewater inlet 2. Alternatively, the connection pipe assembly can be a combination of normal pipes installed with pressurizing pumps. With such features, the flow rate of the water flowing into thelaundry basket 11 a can be increased. - In operation, when the
controller 7 issues a command to open thepipe control valve 5, water in the water storage means 1 can flow into thelaundry basket 11 a via theupstream pipe 4 and thedownstream pipe 6. Since thepipes pipes laundry basket 11 a can be increased, so that the time required for filling thelaundry basket 11 a can be reduced. When the machine conducts a washing cycle, a rinsing cycle, or a spinning cycle of a laundry activity, fresh water may flow into the water storage means 1 until the predetermined level thereof has been reached, and the water stored therein can be used for a next cycle of the laundry activity, thereby significantly reducing the time and power required for completing the laundry activity. - Next, the following paragraphs will illustrate the water-saving advantage of the present invention. For a laundry activity, detergent or other washing chemicals are only added in the washing cycle thereof. Thereafter, several rinsing cycles are conducted to remove the detergent or washing chemicals. After the final rinsing cycle and the spinning cycle thereof is finished, the laundry clothes can be taken to a dryer machine, after which the dried clothes can be put on a person. Generally, the water of the final or the last two rinsing cycles is clean enough to be re-used. Alternatively, a
water quality sensor 11 b (seeFIG. 4 ) can be installed within the water storage means 1 and cooperated with thecontroller 7 to decide whether the water of a rinsing cycle is clean enough to be re-used. This feature will be illustrated in more detail below. To achieve the purpose of re-using a batch of rinse water, the reclaimingpipe 9 is provided, wherein it has one end connected to the water storage means 1 for transferring at least a final batch of rinse water from thelaundry basket 11 a to the water storage means 1. Furthermore, the three-way valve 8 is provided at an outlet of thelaundry basket 11 a so as to control the flow direction of the water sent out from thelaundry basket 11 a, as be fully illustrated below. - The three-
way control valve 8, which is provided for thelaundry basket 11 a for controlling water flow direction, has an inlet port connected to the outlet of thelaundry basket 11 a, a first outlet port connected to another end of the reclaimingpipe 9, and a second outlet port connected to one end of thedischarge pipe 12. When the final rinsing cycle of a laundry activity is finished, thecontroller 7 can operate the three-way control valve 8 to have the inlet port thereof communicated with the first outlet port thereof but not communicated with the second outlet port thereof, so that the water of the final rinse can be reclaimed to the water storage means 1 and thus can be re-used for a next laundry activity, thereby achieving the purpose of saving water. - Furthermore, the
washing machine 11 is provided with theoverflow pipe 10 connected between the water storage means 1 and thedischarge pipe 12. Therefore, when thewater level regulator 3 has a fault, which causes water in the water storage means 1 to reach the overflow outlet thereof, water can flow into thedischarge pipe 12 via theoverflow pipe 10. -
FIG. 2 shows a second embodiment of the present invention, wherein the water storage means 1 may include two water tanks cooperated with twopipe control valves 5. As shown, the left tank of the water storage means 1 is connected with thewater inlet 2 and oneupstream pipe 4. The right tank of the water storage means 1 is connected with the reclaimingpipe 9, theoverflow pipe 10, and oneupstream pipe 4′. Although the embodiment shows two water tanks therein, the water storage means 1 may include more than two tanks. -
FIG. 3 shows a general diagram illustrating that thecontroller 7 is electrically connected with thepipe control valve 5 and the three-way control valve 8 so as to control all cycles of a laundry activity. - Furthermore, the water storage means 1 can be applied to a washer with single laundry basket as well as a washer with two laundry baskets, wherein the spinning action for extracting water for laundry clothes is conducted in a separate basket for the washer with two laundry baskets. Also, the water storage means 1 can be applied to any type of washer, including top-loading washer or front-loading washer.
- The
controller 7 can be adopted from any existing controllers, such as a general microchip controller. Thepipe control valve 5 and the three-way control valve 8 can be adopted from any existing electrical-operated valves. -
FIGS. 4 and 5 respectively show a third embodiment of the present invention and a general diagram of a controller employed in the embodiment, wherein thewater quality sensor 11 b is installed within thelaundry basket 11 a. Furthermore, the water storage means 1 includes afresh water unit 1A and agray water unit 1B, thefresh water unit 1A being connected with thewater inlet 2 for storing fresh water flowing therefrom, thegray water unit 1B being connected with the reclaimingpipe 9 for storing gray water or rinse water reclaimed from thelaundry basket 11 a, the connection pipe assembly including at least twoupstream pipes downstream pipe 6, theupstream pipe 4A being connected between thefresh water unit 1A and thepipe control valve 5A, theupstream pipe 4B being connected between thegray water unit 1B and thepipe control valve 5A, thedownstream pipe 6 being connected between thepipe control 5A valve and thelaundry basket 11 a. (Generally, gray water or greywater is defined as used water generated from domestic activities such as laundry, dishwashing, and bathing, which can be recycled on-site for re-use.) Thewater quality sensor 11 b, which can be adopted from any existing water sensors, can detect the cleanliness of the water of a rinsing cycle of a laundry activity and transmit signal to thecontroller 7. If the cleanliness of the rinse water arrives at a predetermined standard, thecontroller 7 can operate the three-way control valve 8A to allow the rinse water to be reclaimed to thegray water unit 1B via the reclaimingpipe 9. Thus, the water reclaimed in thegray water unit 1B can be re-used for a next laundry activity, so as to save water. If the cleanliness of the rinse water is below the predetermined standard, thecontroller 7 can operate the three-way control valve 8A to allow the rinse water to be discharged out via thedischarge pipe 12. - As shown in
FIG. 4 , thefresh water unit 1A may include at least a water tank for storing fresh water from thewater inlet 2, wherein the water tank may be installed with onewater level regulator 3 at the end of thewater inlet 2 so as to control water level therein (similar to the left tank of the water storage means 1 shown inFIG. 2 ). Furthermore, thefresh water unit 1A may include a pump for thewater inlet 2. The pump can also be controlled by thecontroller 7 to achieve the purpose of increasing the flow rate of the water from the water inlet. Thegray water unit 1B may include a water tank, which is similar to the right tank of the water storage means 1 shown inFIG. 2 . Further, the gray water unit includes at least a water tank so that gray water from separate washing and drying operations can be collected to different water tanks by means of the controller. -
FIG. 5 shows a general diagram illustrating that thecontroller 7 is electrically connected with thepipe control valve 5A, the three-way control valve 8A, and thewater quality sensor 11 b so as to control all cycles of a laundry activity -
FIG. 6 shows a fourth embodiment of the present invention, wherein multiple washing machines share one water storage means 1. Thus, the water storage means 1 can be shared by thelaundry baskets 11 a of the washing machines, and each washing machine has itspipe control valve 5,connection pipes controller 7, and three-way control valve 8. - The water storage means 1 shown in
FIG. 6 may include a water tank being installed with awater level regulator 3, which is similar to the left tank shown inFIG. 2 . Thus, the water tank can be shared by thelaundry baskets 11 a of the washing machines. Alternatively, the water storage means 1 shown inFIG. 6 may include afresh water unit 1A and agray water unit 1B, as described above. - As a summary, the present invention can increase the flow rate of the water flowing from the water storage means 1 to the
laundry basket 11 a by employing one or more connection pipes of large diameter or by installing pressurized pumps for connection pipes of normal diameter, so that the time required for completing a laundry activity can be greatly reduced, and thus the power consumption therefor can also be reduced. Additionally, the rinse water of the laundry activity can be reclaimed to the water storage means for a next laundry activity, so that the water consumption can also be greatly reduced. - Although the present invention has been described with a certain degree of particularity, it is understood that the present disclosure is made by way of example only and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention hereinafter claimed.
