  • the existing washing machines employ almost the same operating cycles to conduct a laundry activity, which generally includes washing, rinsing and spinning cycles. 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.
  • 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.
  • the applicant has contrived an improved washing machine that can mitigate the disadvantages of the existing washing machines.
  • the primary object of the present invention is to provide a washing machine of water storage type, which can save time, power, and water in laundry activities.
  • one embodiment of the washing machine of water storage type may comprise a laundry basket, a water inlet, water storage means, a connection pipe assembly, a pipe control valve, a reclaiming pipe, a discharge pipe, a three-way control valve, and a controller.
  • the water inlet is adapted to be connected to an outside fresh water source.
  • the water storage means is provided with at least one water level regulator that can close or open the water inlet according to water level of the water storage means.
  • the water storage means is capable of storing fresh water from the water inlet and storing at least a final batch of rinse water from the laundry basket.
  • the connection pipe assembly including at least one upstream pipe and at least one downstream pipe, is connected between the water storage means and the laundry basket.
  • the pipes of the connection pipe assembly have a large diameter or are installed with pumps to increase the flow rate of the water entering the laundry basket.
  • the pipe control valve is mounted between the upstream pipe and the downstream pipe of the connection pipe assembly, so that the upstream pipe is connected between the water storage means and the pipe control valve, and the downstream pipe is connected between the pipe control valve and the laundry basket.
  • the reclaiming pipe has one end connected to the water storage means for transferring at least the final batch of rinse water from the laundry basket to the water storage means.
  • the three-way control valve has an inlet port connected to an outlet of the laundry basket, a first outlet port connected to another end of the reclaiming pipe, and a second outlet port connected to one end of the discharge pipe.
  • the controller is provided for controlling the pipe control valve and the three-way control valve.

  • water in the water storage means 1 can flow into the laundry basket 11 a via the upstream pipe 4 and the downstream pipe 6 . Since the pipes 4 , 6 of the connection pipe assembly of the present invention have a diameter than those of conventional washing machines or the pipes 4 , 6 of the connection pipe assembly are installed with pressurizing pumps, the flow rate of the water flowing into the laundry basket 11 a can be increased, so that the time required for filling the laundry basket 11 a can be reduced.
  • 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.
  • the reclaiming pipe 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 the laundry basket 11 a to the water storage means 1 . Furthermore, the three-way valve 8 is provided at an outlet of the laundry basket 11 a so as to control the flow direction of the water sent out from the laundry basket 11 a, as be fully illustrated below.
  • the three-way control valve 8 which is provided for the laundry basket 11 a for controlling water flow direction, has an inlet port connected to the outlet of the laundry basket 11 a, a first outlet port connected to another end of the reclaiming pipe 9 , and a second outlet port connected to one end of the discharge pipe 12 .
  • the controller 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.

Therefore, when the water 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 the discharge pipe 12 via the overflow 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 two pipe control valves 5 . As shown, the left tank of the water storage means 1 is connected with the water inlet 2 and one upstream pipe 4 . The right tank of the water storage means 1 is connected with the reclaiming pipe 9 , the overflow pipe 10 , and one upstream 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 the controller 7 is electrically connected with the pipe control valve 5 and the three-way control valve 8 so as to control all cycles of a laundry activity.
  • 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.
  • the pipe control valve 5 and the three-way control valve 8 can be adopted from any existing electrical-operated valves.

  • the water storage means 1 includes a fresh water unit 1 A and a gray water unit 1 B, the fresh water unit 1 A being connected with the water inlet 2 for storing fresh water flowing therefrom, the gray water unit 1 B being connected with the reclaiming pipe 9 for storing gray water or rinse water reclaimed from the laundry basket 11 a, the connection pipe assembly including at least two upstream pipes 4 A, 4 B and at least one downstream pipe 6 , the upstream pipe 4 A being connected between the fresh water unit 1 A and the pipe control valve 5 A, the upstream pipe 4 B being connected between the gray water unit 1 B and the pipe control valve 5 A, the downstream pipe 6 being connected between the pipe control 5 A valve and the laundry basket 11 a.
  • 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.
  • the water 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 the controller 7 . If the cleanliness of the rinse water arrives at a predetermined standard, the controller 7 can operate the three-way control valve 8 A to allow the rinse water to be reclaimed to the gray water unit 1 B via the reclaiming pipe 9 . Thus, the water reclaimed in the gray water unit 1 B 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, the controller 7 can operate the three-way control valve 8 A to allow the rinse water to be discharged out via the discharge pipe 12 .
  • the fresh water unit 1 A may include at least a water tank for storing fresh water from the water inlet 2 , wherein the water tank may be installed with one water level regulator 3 at the end of the water inlet 2 so as to control water level therein (similar to the left tank of the water storage means 1 shown in FIG. 2 ). Furthermore, the fresh water unit 1 A may include a pump for the water inlet 2 . The pump can also be controlled by the controller 7 to achieve the purpose of increasing the flow rate of the water from the water inlet.
