Description

  The present invention relates to a recycling-type washing water supply device that reuses washing water or rinsing water and supplies it to a washing tub.

  A large amount of water used for washing is required, such as “washing” in which dirt is removed using a detergent, and “rinsing” in which the detergent remaining in the laundry is washed away with water. Water required in large quantities is a problem in terms of cost, but since water is a limited resource, it is also a serious problem from the viewpoint of environmental conservation. In general household use, the remaining hot water of a bath is manually drawn up and used as washing water for washing water. In recent years, for example, the washing machine described in Patent Document 1 includes a pump that pumps up remaining hot water in a bath, and automatically sets and reuses remaining hot water in a rinsing process. To be able to.

  In addition, there is also known one that reuses rinsing water as washing water. For example, in the water washing machine described in Patent Document 2, cleaning wastewater generated by washing and rinsing is purified by a cleaning wastewater purification device including at least an activated sludge treatment tank, a microfiltration tank, and a reverse osmosis filtration tank, The treated water is refluxed as treated water used in the rinsing step.

  Further, the continuous washing system described in Patent Document 3 is composed of a plurality of independent modules having inner and outer drums (double drums), and a continuous flow of a counter flow system in which washing water flows from the opposite direction to the movement of the washing object. Washing machine, a new water supply line for supplying fresh water, a cleaning liquid supply line for supplying a cleaning liquid containing a cleaning agent, a washing water drain line for discharging washed washing water, and a reused water discharged Is provided with a first reused water recycling line that returns the water to the cleaning section through the “reused water distribution tank”.

  However, the water washing machine described in Patent Document 2 does not include a finishing process, and cannot be performed as a series until the final process. In addition, in the continuous laundry system described in Patent Document 3, the finishing agent is supplied from the finishing agent tank to the rinsing part by a line, but the finishing agent tank is one of the tanks supplied to the rinsing part. From the point of view, the system as a whole is still lacking.

  Then, this invention aims at providing the recycle type washing water supply apparatus which can implement from a washing process to a finishing process as a series, and can further consider environmental conservation by promoting reuse of water. .

  The recycling-type washing water supply device of the present invention is a washing water supply device that supplies washing water such as rinsing water at the time of a washing process or rinsing water at the time of a rinsing process to a washing tub in which laundry is washed. The rinsing water from the washing tub is stored and supplied as washing water to the washing tub, the rinsing water storage tank storing rinsing water supplied to the washing tub, and the washing A finishing water storage tank for storing finishing water containing a finishing agent at the time of the finishing process in the tank, and the washing tank after washing in which the washing water is supplied from the washing water storage tank to the washing tank and drained. The rinsing water is supplied from the rinsing water storage tank to the washing tub, and the rinsing water is supplied to the washing water storage tank after the rinsing in the washing tub, and the finishing water is supplied from the finishing water storage tub to the washing tub. For supplying the finishing water to the finishing water storage tank later. Characterized by comprising a flow path switching means for selectively opening and closing a valve provided in the flow path of respectively.

  In the recycling-type washing water supply apparatus of the present invention, the flow path switching unit selectively opens and closes the valves provided in the washing tub, the washing water storage tank, the rinsing water storage tank, and the finishing water storage tank, respectively. Thus, the flow path is switched. By this switching, first, the washing water is supplied from the washing water storage tank to the washing tub for washing in the washing tub. Next, when the washing water containing laundry stains and detergent bubbles is drained from the washing tub after washing, the rinsing water is supplied from the rinsing water storage tank to the washing tub for rinsing in the washing tub. Is done. Next, when rinsing is completed, rinsing water in the washing tub is supplied to the washing water storage tank, and finishing water is supplied from the finishing water storage tank to the washing tub. And when finishing is completed, finishing water is reused by supplying finishing water to a finishing water storage tank. In this way, washing can be performed in a series of steps from the washing step to the finishing step while rinsing water is used as washing water for reuse. In addition, it is possible to reuse even the finishing water in the finishing process.

  If the said finishing water storage tank stores the finishing water containing a paste, it can continue gluing with respect to the laundry which the rinsing process was complete | finished. In addition, the number of times the paste is replenished can be reduced by reusing the finishing water.

  Further, as the rinsing water storage tank, two or more storage tanks for rinsing step by step are provided, and the flow path switching means is arranged in order from one storage tank among the two or more storage tanks. Rinsing water is supplied to the washing tub, and the wash water from the washing tub is supplied to the previous storage tank, or if it is the first storage tank, the valves provided in the respective flow paths to the washing water storage tank are selectively used. It is desirable to open and close. Since two or more storage tanks are provided as rinsing water storage tanks, the rinsing process can be performed according to the number of the storage tanks, so the degree of detergent remaining in the laundry before finishing. Can be further reduced. Accordingly, since the degree of detergent mixed in the finishing water can be reduced, the finished laundry can be made to have a high quality finish.

  The two or more storage tanks have an inflow pipe for supplying washing water from the upper side, an outflow pipe for taking out the washing water stored from the bottom, and a lower side so as to partition the inflow pipe side and the outflow pipe side. It is desirable that a partition plate having a gap as a flow path be provided. The rinse water supplied as wash water to the wash water storage tank may contain detergent bubbles. The detergent bubbles stay in a floating state on the water surface by supplying rinsing water from the upper side of the washing water storage tank through the inflow pipe. When supplying rinsing water as washing water to the washing tub, the partition plate separates the inflow pipe side and the outflow pipe side even if the rinsing water is vigorously taken out from the bottom of the storage tank. There is no worry that the bubbles will flow out with the rinsing water. Therefore, it is possible to make it difficult for the detergent to remain in the laundry after rinsing.

  Furthermore, it is preferable that a sterilizing agent supply device for disinfecting the rinsing water is provided in the rinsing water storage tank upstream of the final rinsing water storage tank among the two or more rinsing water storage tanks. By disinfecting the rinsing water, the water used for rinsing and washing can be kept hygienic. In addition, by putting a sterilizing agent into the rinsing water stored in the rinsing water storage tank before the final stage rinsing water storage tank, the laundry is finally rinsed with rinsing water that does not contain the final stage sterilizing liquid. As a result, the disinfectant and odor residue can be prevented.

  Further, when a water softening device is provided that softens the rinsing water supplied to the rinsing water storage tank, water as rinsing water or water when rinsing water after rinsing is used as washing water is used. By using soft water, the solubility and foaming of the detergent can be increased, so that dirt can be further removed.

  The recycling-type washing water supply device of the present invention can perform washing in a series of steps from the washing process to the finishing process while using the rinsing water as washing water for reuse. Since it can be used, further water conservation can be achieved by promoting the reuse of water. Therefore, the recycling type washing water supply apparatus of the present invention can further consider environmental conservation.

  As described above, the rinsing water supplied from the second storage tank 312 which is the foremost stage of the rinsing water storage tank to the washing machine 20 is subjected to the first rinsing process, so that the washing water is supplied from the washing machine 20 to the first storage tank. It returns to 311 and is stored.

Next, the water washing machine 20 performs a 2nd rinse process. As shown in FIG. 4, the control panel 41 notified of the start of the second rinsing process from the water washing machine 20 opens the third supply valve 323 a and uses the third rinsing water stored in the third storage tank 313 as the third rinsing water. The water is supplied to the washing machine 20 through the branch pipe 323 and the supply pipe 32.
The control panel 41 that has received a notification from the washing machine 20 that the amount of water in the washing tub has reached the predetermined water level closes the third supply valve 323a. The washing machine 20 starts the rinsing operation and performs the second rinsing for a predetermined time on the laundry for which the first rinsing has been completed.

  When the second rinsing process is completed, the water washing machine 20 notifies the control panel 41 of the completion. The control panel 41 opens the second return valve 362a with the drain valve 35a closed, and starts the drain pump 34b, so that the rinsing water flowing out through the drain pipe 35 is discharged from the drain mass 34. Water is supplied toward the second storage tank 312 via the return pipe 36 and the second branch pipe 362. The control panel 41 notified of the end of drainage from the washing machine 20 stops the drainage pump 34b and closes the second return valve 362a.

  As described above, the rinsing water supplied from the third storage tank 313 to the washing machine 20 is subjected to the second rinsing process, so that the rinsing water for the first rinsing process is used as the rinsing water from the washing machine 20 to the upstream of the third storage tank 313. It returns to the 2nd storage tank 312, and is stored.

Next, the water washing machine 20 performs a 3rd rinse process. As shown in FIG. 5, the control panel 41 notified of the start of the third rinsing process from the water washer 20 opens the fourth supply valve 324 a and is fresh water that is stored in the fourth storage tank 314. Is supplied to the washing machine 20 via the fourth branch pipe 324 and the supply pipe 32.
The control panel 41 that has received notification from the water washing machine 20 that the amount of water in the washing tub has reached the predetermined water level closes the fourth supply valve 324a. The washing machine 20 starts the rinsing operation and performs the third rinsing for a predetermined time on the laundry for which the second rinsing has been completed. Since the third rinsing is performed with fresh water, the detergent can be thoroughly washed away from the laundry.

  When the third rinsing process is completed, the water washing machine 20 notifies the control panel 41 of the completion. The control panel 41 opens the third return valve 363a with the drain valve 35a closed, and starts the drain pump 34b, so that the rinsing water flowing out through the drain pipe 35 is discharged from the drain mass 34. Water is supplied toward the third storage tank 313 via the return pipe 36 and the third branch pipe 363. The control panel 41 notified of the end of drainage from the washing machine 20 stops the drainage pump 34b and closes the third return valve 363a.

  In this way, the rinsing water supplied from the fourth storage tank 314 to the washing machine 20 is subjected to the third rinsing process, so that the rinsing water for the second rinsing process is used as the rinsing water from the washing machine 20 to the upstream of the fourth storage tank 314. Return to the third storage tank 313 to be stored.

  In the third rinsing step, which is the third rinsing, rinsing is performed with fresh water. Since the new water is softened by the water softening device 42, the solubility of the detergent is improved, so that the detergent remaining on the laundry can be dissolved in the rinsing water. Further, as described above, the rinsing water with the fresh water used at the third time is used as the second rinsing water, and the rinsing water used at the second rinsing is used as the first rinsing water. The rinsing water used in the rinsing is used as washing water. Accordingly, since the water softened by the water softening device 42 is finally used entirely from washing to rinsing, the solubility and foaming of the detergent can be improved, and thus the dirt can be further removed. .

  In the first rinsing process, the rinsing water in which the sterilizing agent is added by the sterilizing agent supply device 43 is used, but the sterilizing agent is not supplied in the second rinsing process and the third rinsing process. That is, the laundry is stored in the third storage tank by disinfecting the rinsing water stored in the second storage tank 312 that is the first-stage rinsing water storage tank than the fourth storage tank 314 that is the last-stage rinsing water storage tank. Since rinsing with rinsing water that does not include the bactericide stored in 313 and the fourth storage tank 314 is performed, it is possible to prevent the bactericidal agent and odor from remaining.

The water washing machine 20 performs a finishing process when the rinsing process is completed. In the present embodiment, the finishing process is a gluing process.
As shown in FIG. 6, the control panel 41 notified of the start of the finishing process from the washing machine 20 opens the fifth supply valve 325 a and supplies the finishing water diluted with the paste stored in the fifth storage tank 315. Then, the water is supplied to the washing machine 20 through the fifth branch pipe 325 and the supply pipe 32.

  The control panel 41 that has received a notification from the washing machine 20 that the amount of water in the washing tub has reached the predetermined water level closes the fifth supply valve 325a. The washing machine 20 starts the finishing operation, and pastes the laundry after the third rinsing for a predetermined time.

When the finishing process is completed, the water washing machine 20 notifies the control panel 41 of the completion. The control panel 41 opens the fourth return valve 364a with the drain valve 35a closed, and starts the drain pump 34b, so that the finishing water flowing out through the drain pipe 35 is discharged from the drain mass 34. Water is supplied toward the fifth storage tank 315 via the return pipe 36 and the fourth branch pipe 364. The control panel 41 notified of the end of drainage from the washing machine 20 stops the drainage pump 34b and closes the fourth return valve 364a. Thus, the finishing water supplied from the 5th storage tank 315 to the washing machine 20 returns to the 5th storage tank 315 from the washing machine 20 as finishing water again by performing a finishing process, and is stored. And the water-washing machine 20 complete | finishes all the processes of washing by finally dehydrating.
When the finishing water stored in the fifth storage tank 315 has decreased from a predetermined amount, the finishing water diluted with the paste is manually or automatically replenished.

  In the present embodiment, the first branch pipe 361 to the third branch pipe 363 serving as an inflow pipe are provided at the top of each tank of the first storage tank 311 to the third storage tank 313, and the first branch serving as an outflow pipe at the bottom. A branch pipe 321 to a third branch pipe 323 are provided. The first branch pipe 361 to the third branch pipe 363 and the first branch pipe 321 to the third branch pipe 323 are arranged at positions shifted so as not to be directly above and below each other. And the partition plate 31b which used the downward clearance gap as a flow path is provided so that it may partition between. Therefore, even if detergent bubbles are mixed in the washing water returned by the first branch pipe 361 to the third branch pipe 363, the water floats on the water surface on the first branch pipe 361 to the third branch pipe 363 side. Thus, even if the first branch pipe 361 to the third branch pipe 363 are vigorously discharged from the first branch pipe 361 to the third branch pipe 363 side, there is no concern that the detergent foam flows out with the rinsing water or the washing water. Therefore, it is possible to prevent the detergent from adhering to the laundry after rinsing and remaining.

  The third rinse is performed with fresh water, the second rinse is performed with fresh water, the first rinse is performed with the second rinse, and the first rinse is performed. Since water is always used so that fresh water is newly added and circulated as rinsing water, dirt of the rinsing water does not accumulate and does not become severe. Since three rinsing storage tanks (second storage tank 312 to fourth storage tank 314) are provided, rinsing can be performed three times. Hard to remain. Therefore, since the degree of detergent mixed in the finishing water can be reduced, even if the finishing water is reused in the fifth storage tank 315, the finished laundry can have a high quality finish. In addition, since the third rinsing step is performed with fresh water, the laundry can be glued to the laundry with very little residue of the detergent, so that the finished laundry can be of higher quality.

  In this way, washing can be performed in a series of steps from the washing step to the finishing step while using the rinsing water as washing water for reuse. Further, it can be reused even when it reaches the finishing water in the finishing process. Therefore, the reuse of water can be further promoted, and the laundry system 10 can be made in consideration of environmental conservation.
