The present invention relates to a water-saving washing machine, and more particularly, to a rinsing water reuse washing machine which saves water consumption by storing the rinsing water and reusing it in the next washing.

In general, the automatic washing machine performs washing by repeating the process of watering before washing or rinsing, and draining and dehydrating after washing or rinsing. In other words, the washing method of the conventional washing machine is a method of supplying tap water through a water supply pipe to wash and rinse, and then discharge the drained or dehydrated water to the outside through the drain pipe.

Such a conventional washing machine has a problem in that a large amount of water is used because the water after washing or rinsing is discarded through the sewer. The present invention has been made to solve this problem, to provide a water-saving washing machine to store a portion of the water after washing or rinsing process in a separate reservoir and then used again in the first washing.

That is, the present invention was conceived based on the fact that the degree of contamination of the discharged water differs depending on the number of washing, rinsing, or rinsing cycles. Because it is a waste of water too much, it is to save water and reuse it in the first washing or soaking process to reduce water consumption and effectively utilize water resources.

Still another object of the present invention is to provide a rinsing water reuse washing machine that can achieve the object of the present invention by providing a reservoir that can store as much as possible uncontaminated discharge water.

Generally, as shown in FIG. 1, the washing machine includes an external washing tank 14 fixed to the inside of the washing machine case 10, and a washing and dehydrating tank 12 rotatably seated inside the external washing tank 14. And a stirrer 16 provided at the lower center portion of the washing / dehydrating tank 12 and a bottom middle portion of the outer washing tank 14 to be connected to the washing-and-dehydrating tank 12 and the stirrer 16 to supply power. And a motor 50 for driving the washing / dehydrating tank 12 and the stirrer 16 mounted on one side of the bottom surface of the clutch 52 and the external washing tank 14 to transmit the divided portion; and a driven pulley of the clutch 52; It consists of a V-belt 54 or the like that connects the drive pulley of the motor 50 to transmit power.

Looking briefly at the action of such a conventional washing machine, first put the laundry in the combined washing and dehydration tank 12, and set the required work content and time, and then press the start button, the water supply valve 32 in accordance with a specific signal of the control device 80 Open) to supply clean water through the water supply pipe (30) to the washing and dehydrating tank (12) and the external washing tank (14), and to connect the clutch (52) to transfer the power to the washing shaft (17). When driving the 50, the washing operation is performed by rotating the stirrer 16 fixed to one end of the washing shaft 17 to the left and right.

After the washing process, the control device 80 stops the driving of the motor 50 and opens the drain valve 44 to discharge the contaminants contaminated with the detergent through the drain pipe 40. Then, the clutch 52 is connected to the dehydration shaft 18 to remove residual contaminated water contained in the laundry, and then the motor 50 is driven, and the washing and dehydration tank fixed to one end of the dehydration shaft 18 ( 12) is rotated in a constant direction to perform the dehydration work.

This water-washing-draining-dehydration process may be repeated depending on the condition of the laundry, and in addition to this process, a soaking process may be added before washing. The rinsing process performed after the washing process is almost the same operation as the washing process as a whole except that no detergent is added, and this process may be repeated a number of times depending on the state of the laundry.

The present invention is to install the water reservoir 60 in such a conventional washing machine to store the water that can be reused in the discharged water discharged after the rinsing process and reused when necessary.

Referring to the structure of the rinsing water reuse washing machine according to the present invention in detail with reference to the accompanying drawings, the drain pipe 40 in the drain hole 42 formed on one side of the lower bottom surface of the outer washing tank 14 as shown in FIG. A drain valve 44 installed so as to be perpendicular to the longitudinal direction of the pump, a solenoid 46 coupled to one end of the columnar slider 74 of the drain valve 44 to open and close the drain valve 44, and the pump 50 And an inlet 61 of the clutch 52 and the bottom of the external washing tub 14 and the bottom surface of the washing machine case 10, the inlet 61 of which is coupled to one outlet of the drain valve 44 and discharged through the drain valve 44. A reservoir (60) for storing the discharged water to be discharged, a pump (20) installed in the reservoir (60) for supplying the storage water in the reservoir (60) to the washing tanks (12, 14), and connected with the pump (20) Water pipe 22 for transferring the storage water, and check valve 24 for preventing back flow of the water It made composed.

Here, the solenoid 46 and the pump 20 are controlled by the control device 80 and, if necessary, install a water quality sensor not shown in the vicinity of the drain port 42 or the quantity of water not shown on one side of the reservoir 60. By installing a detection sensor can be made to operate the solenoid 46 according to the water quality and quantity.

2 is a view showing one embodiment of the drain valve 44 applied to the rinsing water reuse washing machine of the present invention. Referring to the drawings, the drain valve 44 is generally a cross-shaped cylinder, in the center spaced apart from the inlet 90 and the first drain 92, the diameter of which is equal to or smaller than the diameter of the drain pipe 40. The first and second drain holes 94 are formed to extend from the water inlet 91 and the first drain port 92 and a predetermined distance apart from each other, and are perpendicular to the longitudinal direction of the drain pipe 42. A cross-shaped guide main body 74 having a guide hole 96 in which a rod 95 coupled with a columnar slider 75 described below is formed at an upper portion spaced from and opposed to the second drain 94; And a straight pipe line 70 is inserted along the guide body 74 so as to be movable upward and downward, and along the longitudinal direction of the drain pipe 42 so as to coincide with the inlet 91 and the first drain port 92. Are formed, and are formed side by side spaced apart from the straight pipe (70), the outlet is A bent conduit 72 is formed toward the second drain 94, and the diameter of the drain conduit 42 and the larger or larger sealing part 71 are formed between the straight conduit 70 and the bent conduit 72. It is composed of a cylindrical slider 75 and a solenoid 46 coupled to the rod 75 formed on the upper end of the cylindrical slider 75 to move the cylindrical slider 75 up and down.

On the other hand, by installing the mesh filter (79) at the inlet of the bent conduit 72 it is possible to prevent dirt from entering the recycled storage water.

Figure 3 shows another embodiment of the rinsing water reuse washing machine according to the present invention, in particular made of a stretchable synthetic resin that can be expanded or contracted according to the quantity of the whole or part of the reservoir 60, the washing machine case One application of the rinsing water reuse washing machine provided with an opening 62 and an openable / closing door 64 is provided on the lower one side wall of the 10 to allow the flexible reservoir 60 'to protrude outward.

The flexible reservoir (60 ') is made of a good elastic material such as rubber, or made of a collapsible structure such as bellows shown in the drawings, and any other method can be used if expansion and contraction are possible. . In addition, the door can be used by opening and closing in any way as long as the flexible reservoir can protrude or move to the outside.

Further, in addition to the rinsing water reuse washing machine shown in FIG. 3, a separate guide rod (not shown) is formed on a portion of the bottom of the washing machine case 10 so that the flexible reservoir 60 'can move in a horizontal direction. By installing an unshown reservoir base plate with a roller installed so as to be located at a position, and by installing an unshown spring against the force of the flexible reservoir 60 'to advance outward by water pressure or weight, When a portion of the reservoir (60 ') is protruded to the outside and the amount of water is reduced, the elasticity of the spring acts to cause the elastic reservoir (60') that protruded to the outside to return to the inside.

When the elastic reservoir 60 'is installed in this way, the inlet of the water supply pipe 22 connected to the pump 20 must be installed at the elastic reservoir 60' to be able to pump all the stored water. In addition, it is preferable to install a sensor that can measure the amount of storage in the storage tank (60, 60 ') to send information about the amount of storage to the control device 80 to control the storage and water.

Hereinafter, the operational effects of the present invention will be described.

First, when the control device 80 has a rinsing process or a plurality of rinsing processes, the bent conduit 72 of the cylindrical slider 75 before the draining starts after the last rinsing process is completed in consideration of the capacity or the storage capacity of the reservoir. A specific signal is sent to the solenoid 46 to move the columnar slider 75 up or down so that the inlet is at a position coinciding with the inlet 91 of the guide body 74. Then, the first drain port 92 of the guide body 74 is sealed and the second drain port 94 is opened so that the water drained from the washing tank is connected to the curved pipe 72 and the second drain port 94 of the guide body 74. Through the reservoir 60 is entered.

However, if the pollution degree of the discharged water detected by the water quality detection sensor installed in front of the drain valve 44 is so difficult to reuse, the control device 80 changes its signal to close the curved pipe 72 and close the straight pipe 70. Open to allow drainage to flow out.

When the discharged water enters the reservoir through the bent pipe 72, the water begins to fill the reservoir 60, and when it is saturated to some extent, the expansion tank 60 'is inflated by applying an expansion pressure to the elastic reservoir 60'. Then, a portion of the flexible reservoir pushes open the door 64 installed in the washing machine case 10 and protrudes outward.

Before the above draining process and the dehydration process start, the control device 80 is such that the inlet of the straight conduit 72 of the columnar slider 75 is in a position coinciding with the inlet 91 of the guide body 74. A specific signal is sent to solenoid 46 to move columnar slider 75 up and down. Then, the second drain hole 94 of the guide body 74 is sealed and the first drain hole 92 is opened so that the water dehydrated in the washing tank flows to the outside through the straight pipe line 70 and the first drain hole 92. .

The control device 80 is then provided with a solenoid, such that the closing portion 71 of the cylindrical slider 75 is in a position coinciding with the inlet 91 of the guide body 74 before the dehydration process is finished and the washing process starts. A specific signal is sent to 46 to move the cylindrical slider 75 up and down. All outlets 92 and 94 are then closed so that no further drainage occurs.

When the drain valve 44 is in the closed state as described above, the laundry is put in the combined-use dehydration tank 12, the necessary work content and time are set, and then the start button is pressed. ) Is sent to the water tank of the reservoir 60 is pumped up through the water pipe 22 to supply to the washing tank. Then, the number of reservoirs is gradually reduced and the flexible reservoir 60 'is contracted or horizontally moved by the elasticity of the spring to return to the inside of the washing machine case, and thus the door 64 that was opened is closed again.

On the other hand, when the flexible storage tank 60 'protrudes to the outside due to a large amount of water storage, the flexible storage tank is pumped by a separate sensor installed in the door 64 to pump the stored water into or without the washing operation. To return to the inside of the washing machine case.

As such, after the washing is recycled by storing the stored water, the drain valve 44 is operated so that the straight pipe 70 is opened when the drainage starts, so that the drained water is immediately discharged to the outside.

As described above, the present invention has the effect of reducing water consumption and efficiently using water resources by storing water that is not severely polluted and recycling it during initial washing. In addition, there is also an effect that the washing ability is improved by using the water stored in the water for a certain time, the water temperature increased as the wash water. The present invention also has the effect of storing a large amount of discharged water by employing a flexible reservoir.

Since the present invention described above has been described for exemplary embodiments only for illustrative purposes, those of ordinary skill in the art may implement a variety of modifications and applications based on the present invention, it is the present invention And the true spirit of the intended meaning and the scope of the utility model registration claims set out below.
