The present invention relates to a washing machine, and more particularly, to allow the detergent in the wash water to be drained after washing, while storing the last rinsing water to be reused as wash water for the next washing.

In the conventional washing machine, as shown in FIG. 1 of the accompanying drawings, the outer tub 3 is supported by the plurality of support bars 2 into the main body 1, and a washing shaft and a dehydration shaft are disposed at the center of the outer lower surface of the outer tub. The clutch (4) which is rotatable separately is attached, and the inner tub (5) is installed inside the outer tub (3) so as to be fixed to the dehydration shaft. The belt (6) is provided on one side of the lower surface of the outer tub (3). The motor 7 is fixed to transmit the driving force to the clutch 4 through, and the pulsator 8 is installed in the inner tank 5 to be fixed to the washing shaft.

In addition, a water supply hose 9 is installed at the upper portion of the main body 1 to supply washing water to the inner tank 5, and a drain valve 10 is disposed at the lower portion of the outer tank 3 to discharge the washing water. The installed drain hose 11 is connected, and inside the inner tank 5, the strainer 12 is attached to filter foreign matter (seam, lint) contained in the wash water during washing.

Therefore, put the laundry into the inner tank (5) with the lid installed on the upper part of the main body (1), close the lid and select the start button, washing, rinsing, dehydration within a certain time in accordance with the control signal of the microcomputer Is done.

That is, when the start button is selected, the washing water is supplied to the inner tank 5 through a water supply hose 9 connected to a water pipe (not shown) and filled to a predetermined height so that the motor fixed to one side of the lower surface of the outer tank 3 ( 7) is repeatedly driven in the forward and reverse directions, and this driving force is transmitted to the clutch 4 attached to the center of the lower surface of the outer tub 3 through the belt 6, where the clutch receives the washing signal of the microcomputer and operates it. By transmitting the driving force of the motor 7 received through the belt 6 only to the washing shaft, and accordingly, the pulsator 8 repeats the forward and reverse rotations in the inner tank 5, thereby rotating the pulsator. The laundry is washed as a stream of water that arises.

In the above operation, when water flow occurs by the pulsator 8 to wash the laundry, foreign matter (seam, lint, etc.), which is buried in the laundry, falls off and floats in the wash water, and this foreign matter is attached to the inner tank 5 Filtered by (12).

In this way, when the washing operation is finished, since the drain valve 10 on the drain hose 11 connected to the lower part of the outer tub 3 is opened, the wash water flows out through the long term drain hose 11.

In addition, when rinsing, the same operation as in the above-described washing operation is omitted, and hereinafter, it will be described later in more detail only when dehydration.

During dehydration, the clutch 4 receives the dehydration signal in the state in which the rinsing water used for the rinsing is firstly drained and transmits the one-way driving force of the motor 7 received through the belt 6 only to the dehydration shaft. ) Rotates at a high speed, and the laundry contained in the inner tank is pushed out by centrifugal force and water contained in the laundry is drained out and drained through the drain hose 11, which opens the drain valve 10 installed in the drain hose. So it is possible.

On the other hand, when the inner tank (5) rotates at high speed during dehydration, if the laundry is pulled to one side, the inner tank is vibrated, and the vibration force is transmitted to the outer tank (3), and the vibration force of the outer tank is transmitted to the main body (1), thereby making noise. In this case, since the outer tub 3 and the main body 1 are supported by the plurality of support bars 2, a part of the outer tub 3 and the main body 1 is supported by the support bar 2 when the vibration force of the outer tub 3 is transmitted to the main body 1. Is canceled, and thus noise during dehydration is reduced.

However, such a conventional washing machine has a problem of causing environmental pollution since the detergent contained in the drained wash water is completely dissolved together with the wash water when washing the drained wash water after washing.

In addition, since the wash water as well as the rinsing water are drained as it is, the rinsing water cannot be reused as the washing water at the next washing, and thus there is a problem in that the amount of water used increases.

The present invention has been made in order to solve the above problems, and by changing the structure can be prevented environmental pollution as it is drained with the wash water in a state in which the detergent component included in the wash water completely decomposed. The purpose is to save the water used for washing as the last rinsing water is stored and reused as washing water for the next washing.

According to an embodiment of the present invention for achieving the above object is a filter that is installed detachably on one side of the main body to filter the foreign matter in the wash water and rinsing water drained through the drain hose, and provided in the lower portion of the main body to filter A storage bin for storing the washed water and rinsing water, detergent dissolving means installed in the storage bin to decompose detergent components in the washing water and the rinsing water, and laundry stored in the storage bin connected to one lower side of the storage bin.

The filter 14 is installed to be detachably attached.

In addition, one side of the reservoir 16 is connected to the discharge pipe 19, the discharge valve 18 is installed on the lower side of the reservoir 16 and the washing water and rinsing water stored in the reservoir 16 in accordance with the operation of the discharge valve 18 through the discharge pipe (19) In order to discharge to the outside, the rinsing water stored in the reservoir 16 in accordance with the operation of the pump 20 by connecting the supply pipe 21, the pump 20 is installed on one side of the reservoir 16 in the next wash water In order to be used as a supply to the inner tank (5) through the supply pipe 21, by connecting the reservoir 16 and the discharge pipe 19 to the overflow pipe 22 to wash water and rinsing water coming into the reservoir 16 When the storage capacity of the storage bin is larger than the outlet through the overflow pipe 22, and connected to the air supply pipe 23 to the overflow pipe to supply air through the air supply pipe inside the reservoir 16 To prevent it from becoming vacuum The.

The discharge valve 18 is installed on the upper portion of the valve body (18a) and the magnet (18b) is operated by receiving power, and fixed to the rod of the magnet to move in accordance with the operation of the magnet (18b) to open and close the pipeline It consists of the opening-closing member 18c which makes it possible, and the spring 18d which fits into the rod of the said magnet 18b, and makes the opening-and-closing member 18c elastic.

And the reservoir 16 is formed in the partition 24 to be located between the discharge pipe 19 and the supply pipe 21 connected to the reservoir to pump the rinsing water stored in the reservoir 16 to be reused as wash water for the next wash. When operating (20), the suction force of this pump is not transmitted directly to the bottom surface of the reservoir (16) by the partition (24).

When described below with a focus on the action of the main portion of the operation of the present invention configured as described above.

When the laundry put into the inner tank 5 is washed by the detergent contained in the wash water and the long-term wash water, the drain valve 10 installed in the drain hose 11 is operated so that the wash water is washed out along the drain hose 11. The washing water drained from 3) enters the housing 13 fixed to one side of the main body 1, and the wash water entering the housing 13 is detachably attached or detached through the outer opening of the housing 13. Foreign matters such as seams or lint cloth contained in the wash water are collected in the filter body 14b constituting the filter 14 while passing through the hole 14a. 16).

When the amount of wash water stored in the storage bin 16 is larger than the capacity of the storage bin, a part of the wash water stored in the storage bin 16 overflows through the overflow pipe 22 and is discharged to the outside through the discharge pipe 19. do.

In this way, when the wash water used for washing is stored in the reservoir 16, clean water is supplied to the inner tank 5 through the water hose 11 to start the first rinsing. 17) is powered on and emits ultraviolet rays, so that the detergent component in the wash water stored in the reservoir 16 is completely decomposed by the ultraviolet rays.

Meanwhile, when the first rinsing is completed, the magnet 18b of the drain valve 10 installed in the drain hose 11 automatically pulls the opening / closing member 18c fixed to the rod of the magnet, so that the opening / closing member of the spring 18d Receiving elasticity, while moving upwards to open the conduit of the valve body (18a) and the wash water previously stored in the reservoir (16) is discharged to the outside through the discharge pipe (19) and the first rinsing water to the reservoir (16) After entering and discharged to the outside through the discharge pipe 19, the ultraviolet lamp 17 is turned off.

When the wash water and the rinsing water are discharged from the air is supplied through the air supply pipe 23 connected to the overflow pipe 22 and the air is supplied to the reservoir 16 through the overflow pipe 22 to the inside of the reservoir The washing and rinsing water are discharged smoothly since the vacuum does not become a vacuum state.

When the discharge is completed to the rinsing water immediately before the wash water and the last rinsing water used for washing by the above action, the discharge valve 18 installed in the discharge pipe 19 is closed again and clean water is supplied through the water supply hose 9. After the final rinsing is completed, the final rinsing is completed, the drain valve 10 installed in the drain hose 11 is opened, so the last rinsing water is drained through the drain hose 11 to store the reservoir 16 In this case, the ultraviolet lamp 17 lights up for a predetermined time and emits ultraviolet rays, thereby sterilizing various bacteria in the rinsing water stored in the reservoir 16 by the ultraviolet rays.

In this way, the last rinse water is stored in the reservoir 16, and when the next washing water reuse button is selected, the pump 20 installed in the supply pipe 21 is operated to wash the rinse water stored in the reservoir 16. The pumping and thus rinsing water is supplied back to the inner tank 5 along the supply pipe 21 and is reused as wash water.

When the last rinsing water for reuse as the wash water for a long time stored in the reservoir 16, the fine suspended solids in the rinsing water is deposited on the bottom surface of the reservoir 16, as described above As such, when the pump 20 is operated to reuse the rinsing water as washing water in the next washing, when the suction force of the pump is immediately transmitted to the bottom of the reservoir 16, the suspended solids deposited on the bottom of the reservoir are discharged. In order to prevent the rinsing water which is clean by receiving suction power, the partition 24 is formed to be located between the discharge pipe 19 and the supply pipe 21 into the reservoir 16 so as to prevent this from happening. Immediately prevented the delivery to the bottom surface of the reservoir (16).

On the other hand, if there is a large amount of foreign matter such as seams or lint collected on the filter body 14b constituting the filter 14 after washing, the filter 14 should be removed from the housing 13 to remove the foreign matter. At this time, if the rotating member 14d rotatably hinged to the filter body 14b is rotated using the handle 14e, the rotating member 14d is released from the housing 13 by the thread 14c. As a result, when the filter 14 is removed from the housing 13 and the foreign matter is removed while the filter is removed, the filter 14 may be mounted on the housing 13 again.
