Abstract

(57) [Summary] [Purpose] A washing machine puts water in a washing tub, washes it, drains it after washing, rinses it, and finally dehydrates it.
The water supply time is determined by the capacity of the water supply tank and the cross-sectional area of the pipe of the water when it is directly put into the washing tub, but the cross-sectional area of the pipe cannot be easily changed. Therefore, when the capacity of the washing tub becomes large, The water supply time will inevitably be long. Similarly, for drainage, the cross-sectional area of the water distribution pipe cannot be easily changed, so that the drainage time will inevitably become longer as the capacity of the washing tub increases. The present invention provides a washing machine that can shorten the water supply time and drainage time even if the cross-sectional areas of the water supply pipe and the water distribution pipe do not change. [Structure] (2) Provide a water tank (1) above the washing tank. The water tank has a large diameter (6) water valve at the bottom and (4) at the top
Open when the air vent and water tank are empty, and close when it is full (5) Have an air vent valve. Also, a large diameter (8) drain valve and (7) air vent hole are provided at the bottom of the washing tub (3)
Provide a drainage tank. It is a washing machine composed of the above parts.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 As shown in FIG. 1, the present invention is a washing machine in which a water supply tank is provided in the upper part of the washing tub and a drainage tank is provided in the lower part to shorten the time for supplying and draining.

[0002]

[Prior art]

 In a conventional washing machine, as shown in Fig. 2, water was supplied directly from the tap water to the washing tub, and drained directly to the sewer pipe after washing was completed.

[0003]

[Problems to be solved by the device]

 This had the following drawbacks. The time of water supply was determined by the capacity of the washing tub and the inner diameter of the water pipe. That is, the inner diameter of the water pipe could not be increased, and as the capacity of the washing tub was increased, the water supply time was inevitably increased. Similarly, the time for draining is determined by the capacity of the washing tub and the inner diameter of the sewer pipe. Therefore, the larger the capacity of the washing tub, the longer the draining time was inevitably required. This plan was devised to eliminate the drawbacks.

[0004]

[Means for solving the problem]

 Provide a water tank above the washing tub of the washing machine. The water tank has a large diameter water supply valve, an air vent hole, and an air vent valve that opens when the water tank is empty and closes when the tank is full. This water tank is filled with water in advance, and water is supplied from the water tank to the washing tank when necessary. At this time, since the diameter of the water supply valve in the water supply tank is large, water can be supplied in a short time. In addition, a drain tank with a large diameter drain valve and an air vent hole will be installed at the bottom of the laundry tank. The drainage tank is always emptied and drained from the washing tank to the drainage tank when necessary. However, the diameter of the drainage valve of the drainage tank is large, so the drainage time can be shortened.

[0005]

[Action]

 Referring to FIG. 1, it is (2) a washing machine having (1) a water supply tank at the upper part of a washing tub and (3) a drain tank at the lower part. (1) Fill the water tank with water from the tap. Connect the water supply and the water tank so that the water pressure does not leak under normal water pressure. (1) Provide (4) air vent hole and (5) air vent valve at the top of the water tank. (5) Air vent valve (1) Close when the water tank is full and (1) Open when there is a space above the water tank. (1) At the bottom of the water tank, (2) Provide a water supply valve (6) for supplying water to the washing tank. (2) Allow drainage to flow from the washing tub to (3) drainage tank via (8) drain valve, and ensure that normal water pressure does not leak between the (2) washing tub and (3) drainage tub. Connect to. (3) Provide an air vent hole (7) above the drainage tank. (7) Air vent The opening of the hole should be (2) above the top of the washing tub. (2) Drain from the bottom of the drainage tank into the sewer.

【Example】

 Hereinafter, examples of the present invention will be described. The present invention is a washing machine in which a water supply tank is provided above the washing tub and a drain tank is provided below the washing tub. The water tank at the top and the drain tank at the bottom are independent of each other, and it is possible to attach only one of them. If only the water tank is attached, the water supply time can be shortened, and if only the drain tank is attached, the drain time can be shortened.

[0007]

【The invention's effect】

 FIG. 3 The washing process will be described. Water supply process to the washing tub: The water tub contains water that has been filled from the water supply since the end of the previous wash and fills the water in the water tub at the same time as the start of washing. At this time, the time required is such that the cross-sectional area of the water supply valve is reduced to the reciprocal of the multiple of the cross-sectional area of the water pipe. Laundry process: This required time remains unchanged, and water is flowing from the tap into the water tank that was emptied during this period. Draining process from the washing tub: The water is drained to the drain, but the required time at this time is the cross section of the drain valve is shortened to the reciprocal of the multiple of the cross section of the sewer pipe. During this period, water is flowing from the tap into the empty water tank. Dehydration: The required time remains unchanged, and if the water tank that was emptied during this period is not full, water is flowing from the tap. Also, at this time, the drainage tank is draining the full water into the sewage. Water supply process to washing tub: Water is supplied again for rinsing. The operation is the same as above. At this time, the drainage tank drains into the sewage until the water is full. Rinsing process: The required time remains unchanged, and water is flowing from the tap into the empty water tank during this period. At this time, the drainage tank is draining the sewage until the water is full. After that, repeat ~ depending on the number of rinses. Lastly, washing is performed from the washing tub by draining the water from the drainage process. As described above, by providing a water tank and a drain tank so that water can be supplied and drained at the same time as washing and rinsing, the washing time can be shortened compared to the conventional method.
