Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are given by way of illustration and explanation only, not limitation.
Referring to fig. 1 and 2, the water saving and using system provided by the invention comprises a clean water container 1, a plurality of transitional water containers and a water using unit 2, wherein the clean water container 1 is connected with the water using unit 2 through a water inlet waterway 3, and the transitional water containers are respectively connected with the water using unit 2 through the water inlet waterway 3 and a water returning waterway 4; the water using unit 2 can perform water using operation for multiple times; except for the last water using operation (for example, the fourth water using operation in fig. 2), the other water using operations of the water using unit 2 correspond to respective transitional water containers for supplying water; the post-primary-operation drain of the water usage unit 2 can be returned to the interim water container for supplying water for the preceding primary operation (for example, in fig. 2, the first water usage operation is the preceding water usage operation, the second water usage operation is the succeeding water usage operation, and the second water usage operation is the third water usage operation, the second water usage operation is the preceding water usage operation, the third water usage operation is the succeeding water usage operation, the third water usage operation is the fourth water usage operation, the third water usage operation is the preceding water usage operation, and the fourth water usage operation is the succeeding water usage operation); when the water unit 2 is used for the last water using operation, the clean water in the clean water container 1 can be conveyed to the water unit 2.
The clean water container 1 can be one or a plurality of.
In the water-saving system, except for the last water-using operation of the water-using unit 2, each other water-using operation of the water-using unit 2 corresponds to a respective transitional water container for supplying water, for example, in each other water-using operation, one water-using operation corresponds to one transitional water container or a plurality of transitional water containers; the discharge water of the latter one-time water-use work of the water-using unit 2 can flow back into the transitional water container for supplying water of the former one-time water-use work; when the water unit 2 is used for the last water using operation, the clean water in the clean water container can be conveyed to the water unit 2. In this way, except for the first time of water using operation drainage to be drained as the waste water (for example, the waste water can be drained to a waste water tank), each other subsequent time of water using operation drainage can flow back to the corresponding transition water container to be used as the water supply of the previous time of water using operation, so that under the condition that the clear water supply and the sewage treatment capacity are limited, the times of water using operation can be effectively increased, less sewage is drained when a whole water using operation program is completed, the water saving effect is improved, correspondingly, the volume of the sewage tank can be reduced, and the volume of the clear water container is correspondingly increased.
In addition, the intermediate water container may be two, such as the first intermediate water container 5 and the second intermediate water container 23 in fig. 1. Alternatively, the number of the transitional water containers may be three, such as a first transitional water container, a second transitional water container and a third transitional water container in fig. 2.
Of course, the transitional water containers may be other numbers, and the specific number is not particularly limited. For example, in one embodiment, the water saving and using system comprises a clean water container 1, N transitional water containers and a water using unit 2, wherein the clean water container 1 is connected with the water using unit 2 through a water inlet waterway 3, and the N transitional water containers are respectively connected with the water using unit 2 through a water inlet waterway 3 and a water return waterway 4; the water using unit 2 can perform water using operation for N +1 times; when the water using unit 2 carries out the first water using operation of N +1 water using operations, the drained water of the second water using operation in the first transitional water container 5 in the N transitional water containers is conveyed into the water using unit 2, and after the first water using operation is finished, the drained water of the first water using operation can be drained; when the water using unit 2 carries out the (N + 1-m) th water using operation of the (N + 1) th water using operation, the drained water of the (N-m + 2) th water using operation in the (N + 1-m) th transition water container in the N transition water containers is conveyed into the water using unit 2, and after the (N + 1-m) th water using operation is finished, the drained water of the (N + 1-m) th water using operation can flow back into the (N-m) th transition water container; when the water unit 2 is used for carrying out the (N + 1) th water using operation, clear water in the clear water container 1 is conveyed to the water unit 2, and after the (N + 1) th water using operation is finished, the discharged water of the (N + 1) th water using operation can flow back to the nth water container; wherein N is a natural number not less than 2, and m is a natural number not less than N-1 and not 0.
Thus, when the water using unit performs the (N + 1-m) th water using operation of the (N + 1) th water using operation, the (N-m + 2) th water using operation drain from the (N + 1-m) th transfer water container is transferred to the water using unit, and after the (N + 1) -m) th water using operation is completed, the (N + 1-m) th water using operation drain can be returned to the (N-m) th transfer water container, and simultaneously, when the (N + 1) th water using operation is performed by the water using unit, the fresh water in the fresh water container is transferred to the water using unit, and after the (N + 1) th water using operation is completed, the (N + 1) th water using operation drain can be returned to the (N) th transfer water container, so that, in addition to the first water using operation drain being discharged as waste water, the other transfer water using operation drain can be returned to the transfer water using as the previous water using operation drain for the each water using operation, and thus, in case where the supply and sewage disposal capabilities are limited, the number of the water using operation can be effectively increased, and the volume of the fresh water tank can be accordingly, and the volume of the water can be reduced, and the volume of the sewage tank can be correspondingly increased, and the sewage can be reduced, and the volume can be correspondingly reduced.
For example, when N =2,m is 1, the pumping unit 10 in fig. 1 is capable of pumping the 3 rd of the 3 nd of the 2 nd of the transitional water containers into the watering unit 2 when the watering unit 2 is performing the 2 nd of the 3 nd of the hydraulic works, and the 2 nd of the hydraulic works is capable of discharging into the 1 st of the transitional water containers after the 2 nd of the hydraulic works is completed; when the water using unit 2 performs the 3 rd water using operation, the water pumping unit 10 can pump the clean water in the clean water container 1 into the water using unit 2, and after the 3 rd water using operation is completed, the drained water of the 3 rd water using operation can be drained into the 2 nd transitional water container;
for another example, when N =3, m is 1 and 2, the pumping unit 10 can pump the 3 rd of the 3 nd of the transitional water containers into the watering unit 2 when the watering unit 2 performs the 2 nd of the 4 th of the watering works, and the 2 nd of the transitional water containers can be drained into the 1 st of the transitional water containers after the 2 nd of the watering works is completed; when the water using unit 2 carries out 3 rd water using operation of 4 water using operations, the water pumping unit 10 can pump 4 th water using operation drainage in a 3 rd water using container in 3 transitional water containers into the water using unit 2, and after the 3 rd water using operation is finished, the 3 rd water using operation drainage can be drained into the 2 nd transitional water container; when the water using unit 2 performs the 4 th water using operation, the water pumping unit 10 can pump the clean water in the clean water container 1 into the water using unit 2, and after the 4 th water using operation is completed, the 4 th water using operation can discharge the discharged water into the 3 rd transitional water container. Of course, one water-using operation can correspond to one transitional water container or a plurality of transitional water containers.
In addition, in addition to the first-time water-consuming operation drainage, in one embodiment, the latter-time water-consuming operation drainage can directly flow back to a transitional water container for supplying water for the former-time water-consuming operation, or in another embodiment, in order to precipitate the latter-time water-consuming operation drainage, so that the drainage discharged into the corresponding transitional water container has better water quality, a water return waterway 4 between each transitional water container and the water-consuming unit 2 is respectively provided with a buffer water container, the other water-consuming operation drainage of the water-consuming unit 2 except the first-time water-consuming operation drainage is firstly buffered in the buffer water container corresponding to the water-consuming operation drainage, and when the corresponding buffer water container reaches a preset water level line or a preset buffering amount or a preset time, the water-consuming operation drainage in the buffer water container corresponding to the water-consuming operation drainage flows back to the corresponding transitional water container, so that impurities in the drainage can precipitate in the buffer water container to reduce the content of impurities flowing back to the corresponding transitional water container, thereby improving the water quality in the transitional water container.
In addition, the buffer water containers respectively arranged on the backwater waterway 4 between each transition water container and the water using unit 2 can be a plurality of independent buffer water containers, or as shown in fig. 1, each buffer water container is the same buffer water container 6, so that the water saving and using system is simplified, and the content of impurities flowing back to the corresponding transition water container can be reduced. For example, after the second water using operation is completed, the drained water may be drained into the water caching container 6, and then the water using unit performs the third water using operation, at this time, when the drained water of the second water using operation drained into the water caching container 6 reaches a preset water level or a preset buffer amount or a preset time, the drained water flows back into the first transition water container 5 for supplying water to the first water using operation. Of course, the first transitional water container 5 may be one or plural.
In addition, in order to improve the quality of the water returned to the transitional water container for drainage, in one embodiment, referring to fig. 1, a return water filtering device 7 is arranged on the return water path, so that impurities in the drainage water of the water-using operation can be filtered by the return water filtering device 7, and the cleanness of the next water-using operation is improved. And/or, similarly, in order to improve the cleanness of the operation water of the water using unit 2, in an embodiment, referring to fig. 1, the inlet water channel 3 is provided with an inlet water filtering device 8, so that the inlet water filtering device 8 can filter and purify the inlet water flowing into the water using unit 2, thereby improving the quality of the inlet water.
In addition, the number of the backwater filtering device 7 and the inlet water filtering device 8 may be multiple, for example, in one embodiment, an inlet water path 3 and a backwater water path 4 are connected between each transitional water container and the water using unit, the inlet water path 3 is provided with the inlet water filtering device 8, and the backwater water path is provided with the backwater filtering device 7. Or, the backwater filter device 7 and the intake filter device 8 may be respectively one, for example, the same water inlet waterway 3 may be shared between the fresh water container and the water using unit 2, and the one water inlet waterway 3 is provided with the one intake filter device 8, that is, the same water inlet filter device 8 may be shared between the fresh water container and the plurality of transitional water containers, and simultaneously, the same backwater waterway 4 may be shared between the plurality of transitional water containers and the water using unit 2, and the backwater waterway 4 is provided with the one backwater filter device 7, that is, the same backwater filter device 7 may be shared by the plurality of transitional water containers.
In addition, the backwater filter device 7 and the inflow filter device 8 may be the same type of filter or different types of filters. In addition, the backwater filter 7 and the influent water filter 8 may be of any type of filter as long as they can filter and purify the backwater and the influent water, respectively.
In the water saving and using system, the fresh water container and the plurality of interim water containers and the water using unit 2 may be arranged in a height direction, for example, in an embodiment, the fresh water container and the plurality of interim water containers may be arranged above the water using unit 2, at this time, the inflow water respectively flowing from the fresh water container and the plurality of interim water containers to the water using unit 2 may flow downward by its own weight or may flow into the water using unit 2 by its own intake pump, and the water service drain returning to the interim water containers may be drained into the corresponding interim water containers by its own drain pump of the water using unit 2. Alternatively, in another embodiment, the fresh water container and the plurality of transitional water containers may be disposed below the water using unit 2, in which case, the inlet water respectively flowing from the fresh water container and the plurality of transitional water containers to the water using unit 2 may flow into the water using unit 2 by using the own inlet pump of the water using unit 2, and the working water drain returning to the transitional water containers may be drained into the corresponding transitional water containers under the own gravity or under the own drain pump of the water using unit 2.
In addition, in the water saving and using system, the clean water container and the plurality of transitional water containers and the water using unit 2 may be arranged in the height direction or in the horizontal direction, that is, in one embodiment, no matter how the clean water container and the plurality of transitional water containers and the water using unit 2 are arranged, a separate water inlet pump may be disposed on the water inlet waterway 3, and a separate water return pump may be disposed on the water return waterway 4. In addition, in one embodiment, the water inlet of the fresh water container and the water inlet of the multiple transition water containers to the water using unit 2, and the water discharging of the water using unit 2 to the transition water container can be realized by the same water pumping unit 10, for example, as shown in fig. 1, the water inlet waterway 3 and the water return waterway 4 comprise a common waterway section 9, the water pumping unit 10 is arranged on the common waterway section 9, and the water pumping unit 10 is used for supplying water to each water using operation and for returning the water discharging to the transition water container for supplying water to the previous water using operation. Thus, when the water using unit 2 is filled, the water pumping unit 10 is activated to pump the water in the fresh water container and the plurality of interim water containers into the water using unit 2 according to the demand of the water using operation. After the water using operation is finished, the water pumping unit 10 is started, and the drainage water of each water using operation of the water using unit 2 can be pumped into the corresponding transitional water container. Thus, the structure of the water saving and using system can be simplified and the cost can be reduced by the same water pumping unit 10.
In addition, in an embodiment, as shown in fig. 1, the water inlet path 3 further includes a first water inlet path section 11 and a second water inlet path section 12, and the water return path 4 further includes a first water return path section 13 and a second water return path section 14, wherein the first water inlet path section 11 and the first water return path section 13 are connected in parallel to one end of the common path section 9, and the second water inlet path section 12 and the second water return path section 14 are connected in parallel to the other end of the common path section 9; the clean water container 1 and the plurality of transitional water containers are respectively connected in parallel on a first water inlet road section 11 through respective first water inlet control valves 24, a water inlet filtering device 8 is arranged on the first water inlet road section 11, a cache water container 6 and a backwater filtering device 7 which are sequentially arranged in the backwater direction are arranged on a first backwater road section 13, and a first backwater control valve 15 and a second backwater control valve 16 which are respectively positioned at two sides of the cache water container 6 are arranged on the first backwater road section 13; a second water inlet control valve 17 is provided on the second water inlet section 12, and a plurality of transitional water containers are connected in parallel to the second water return section 14 through respective third water return control valves 25. Further, the water using unit 2 is connected to a sewage tank 22 through a drain line, and a sewage control valve 26 is provided on the drain line.
Thus, in the embodiment shown in fig. 1, when the water unit 2 is used for the first water using operation, the first water transitional container 5 feeds water into the water using unit 2, the first water inlet control valve 24 of the first water transitional container 5 is opened, the second water inlet control valve 17 is opened, all other valves are closed, and water in the first water transitional container 5 (pre-stored water or second water using operation drain of the water using unit) can be purified by the water pumping unit 10 through the water inlet filtering device 8 and then pumped into the water using unit 2 to perform the first water using operation. After the first-time water-using work is completed, the sewage control valve 26 is opened and the other valves are closed to discharge the first-time water-using work discharge of the water using unit 2 into the sewage tank.
Then, the water using unit 2 performs the second water using operation, the first water inlet control valve 24 of the second water transitional container 23 is opened, the second water inlet control valve 17 is opened, all other valves are closed, and the water in the second water transitional container 23 (previously stored water or third water using operation drain of the water using unit) may be purified by the water inlet filtering device 8 by the water pumping unit 10 and then pumped into the water using unit 2 to perform the second water using operation. After the second water using operation is completed, the first water return control valve 15 is opened, the other valves are closed, the second water using operation discharged water flows into the buffer water container 6 for precipitation, and when the buffer water container 6 reaches a preset water level or a preset buffer amount or a preset time, the second water return control valve 16 and the third water return control valve 25 of the first transition water container 5 are opened, at this time, the first water return control valve 15 is opened when the second water using operation discharged water of the water using unit 2 is not discharged yet, or the first water return control valve 15 may be opened or closed when the second water using operation discharged water of the water using unit 2 is finished, and the other valves are closed, so that the second water using operation discharged water of the buffer water container 6 flows into the first transition water container 5 after being filtered and purified by the water return filter device 7 under the action of the water pumping unit 10.
Then, the water using unit 2 performs a third water using operation, the first water inlet control valve 24 of the fresh water container 1 is opened, the second water inlet control valve 17 is opened, all other valves are closed, and the fresh water in the fresh water container 1 can be purified by the water inlet filtering device 8 under the action of the water pumping unit 10 and then pumped into the water using unit 2 to perform the third water using operation. After the third water using operation is completed, the first water return control valve 15 is opened, the other valves are closed, the third water using operation discharge water flows into the buffer water container 6 for precipitation, and when the buffer water container 6 reaches a preset water level or a preset buffer amount or a preset time, the second water return control valve 16 and the third water return control valve 25 of the second transition water container 23 are opened, at this time, the first water return control valve 15 is opened when the third water using operation discharge water of the water using unit 2 is not completed, or the first water return control valve 15 may be opened or closed when the third water using operation discharge water of the water using unit 2 is completed, and the other valves are closed, so that under the action of the water pumping unit 10, the third water using operation discharge water of the buffer water container 6 flows into the second transition water container 23 after being filtered and purified by the water return filtering device 7.
In addition, in the water-saving system, as described above, for example, the water in the first transitional water container 5 may be pre-stored water or discharged water for the second water-using work of the water-using unit, and when the first water-using work is performed, the first transitional water container 5 is empty or the existing amount of water cannot satisfy the first water-using work, the water-saving system may be configured such that the water-using unit 2 can take water from the clean water container. Therefore, in the water saving and using system, in one embodiment, when there is no water in the transitional water container corresponding to the water using operation or the water amount cannot meet the demand of the water using operation, the water saving and using system can deliver the clean water in the clean water container 1 to the water using unit 2. Of course, the volume of the intermediate water container itself corresponding to this water-consuming operation is such that the water demand of the water-consuming unit 2 can be met, i.e. the full water content of the intermediate water container is such that the water demand of the water-consuming unit 2 can be met. For another example, as mentioned above, the water in the second transitional water container 23 may be pre-stored water or the water unit's third-time water-using operation drain, and when the second-time water-using operation is performed, the second transitional water container 23 is empty or the existing amount of water cannot satisfy the second-time water-using operation, the water-saving system may be configured such that the water-using unit 2 can take water from the clean water container. Thus, the water demand for each water-using operation can be further satisfactorily satisfied.
In addition, each valve can be a manual control valve, that is, a user can manually open and close each manual control valve according to the actual use requirement. Alternatively, as shown in fig. 1, the water-saving system comprises a control unit 18 and first sensors 19 for detecting the amounts of water in the fresh water container 1 and the plurality of interim water containers, respectively, and the control unit 18 is capable of controlling the water supply for each water-using work based on the detected values of the respective first sensors. Further, each of the valves described above may be automatically controlled by the control unit 18. For example, the buffer water container 6 is provided as the second sensor 20, and the control unit 18 may determine whether the drain of the buffer water container 6 reaches a preset water level or a preset buffer amount or a preset time according to the second sensor 20. In addition, the sewage container 22 may be provided with a third sensor 21, and the control unit 18 may judge the amount of water in the sewage container 22 based on the third sensor 21.
In addition, the control unit 18 may determine the water volume of the fresh water container 1 according to the first sensor 19 of the fresh water container 1, and in the actual water usage operation, if the water volume of the fresh water container 1 is insufficient, for example, lower than a preset water level or lower than a preset weight, the control unit 18 controls all the shutdown operations, stops the water usage unit 2, and issues an alarm prompt.
In addition, each sensor may be a liquid level sensor, a weight sensor, or an infrared sensor. Or may be other sensors capable of detecting the amount of water.
In addition, the water-saving and water-using system can be applied to various water-using occasions, such as clothes washing or other washing, as long as the drainage water of the next water-using operation can be reused. For example, in one embodiment, as shown in fig. 1, there are two transitional water containers, wherein the water using unit 2 is a laundry washing apparatus capable of performing a triple-use operation, wherein the first time use of water is a main washing operation, such as a washing operation, the second time use of water is a first rinsing operation, and the third time use of water is a second rinsing operation. Therefore, under the condition of limited clear water supply and sewage treatment capacity, the times of washing the clothes can be effectively increased, less sewage is discharged when a whole clothes washing operation program is completed, the water-saving effect is improved, the volume of the sewage tank can be correspondingly reduced, and the volume of the clear water container is correspondingly increased.
Further, the present invention provides a water saving and using method, referring to fig. 1 and 2, in which the drain water of the latter one of the plurality of water using works performed by the water using unit 2 can be returned to the interim water tank for supplying water of the former one; when the water using unit 2 carries out the last water using operation, the clean water in the clean water container 1 is conveyed to the water using unit 2; the water unit 2 is used for supplying water through the corresponding transition water container except the last water using operation of the water unit 2.
In the water-saving using method, the discharged water of the latter one of the plurality of water-using works performed by the water-using unit can flow back into the interim water container for supplying water of the former one; when the water using unit carries out the last water using operation, the clean water in the clean water container is conveyed to the water using unit; the water using unit supplies water through the corresponding transitional water container except for the last water using operation. Thus, except that the first time water using operation drainage is discharged as the waste water (for example, the waste water can be discharged to a waste water tank), each other next time water using operation drainage can flow back to the corresponding transition water container to be used as the water supply of the previous time water using operation, thus, under the condition that the clear water supply and the sewage treatment capacity are limited, the times of the water using operation can be effectively increased, the sewage discharged when a whole water using operation program is completed is less, the water saving effect is improved, correspondingly, the volume of the sewage tank can be reduced, and the volume of the clear water container is correspondingly increased.
The clean water container 1 may be one or may be plural.
In addition, in the water saving method, there may be two transitional water containers, such as the first transitional water container 5 and the second transitional water container 23 in fig. 1. Alternatively, the number of the transition water containers may be three, such as the first transition water container, the second transition water container and the third transition water container in fig. 2.
Of course, the transitional water containers may be other numbers, and the specific number is not particularly limited. For example, in one embodiment, when the water using unit 2 performs the first water using operation of N +1 water using operations, the second water using operation drainage in the first water using container 5 of the N water using containers is transferred to the water using unit 2, and after the first water using operation is completed, the first water using operation drainage is drained; when the water using unit 2 carries out the (N + 1-m) th water using operation of the (N + 1) th water using operation, the drained water of the (N-m + 2) th water using operation in the (N + 1-m) th transition water container in the N transition water containers is conveyed into the water using unit 2, and after the (N + 1-m) th water using operation is finished, the drained water of the (N + 1-m) th water using operation flows back into the (N-m) th transition water container; when the water unit 2 is used for the (N + 1) th water using operation, clean water in the clean water container 1 is conveyed to the water unit 2, and after the (N + 1) th water using operation is finished, the (N + 1) th water using operation is drained and then flows back to the Nth transition water container; wherein N is a natural number not less than 2, and m is a natural number not less than N-1 and not 0.
In the water saving method, when the water using unit performs the (N + 1-m) th water using operation of the (N + 1) -th water using operation, the (N-m + 2) -th water using operation discharge water in the (N + 1-m) th transition water container is supplied to the water using unit, and after the (N + 1) -m) th water using operation is completed, the (N + 1) -m) th water using operation discharge water can be returned to the (N-m) th transition water container, and simultaneously, when the water using unit performs the (N + 1) -th water using operation, the fresh water in the fresh water container is supplied to the water using unit, and after the (N + 1) -th water using operation is completed, the (N + 1) -th water using operation discharge water can be returned to the (N-m) th transition water container, so that, in addition to the first water using operation discharge water as waste water, the other water using operation discharge water can be returned to the corresponding transition water using water as supply water for the discharge operation of the each water using operation, and thus, the number of times of the water using operation can be effectively increased, and the volume of the fresh water container can be correspondingly reduced, and the volume of the waste water can be accordingly, and the volume of the water saving container can be increased.
In addition, in addition to the first-time water-use operation drainage, in one embodiment, the latter-time water-use operation drainage may directly flow back into the transitional water container for supplying water to the former-time water-use operation, or in another embodiment, in order to precipitate the latter-time water-use operation drainage so that the drainage drained into the corresponding transitional water container has better water quality, the drainage of each water-use operation of the water-use unit except the first-time water-use operation drainage is buffered first and then flows back into the corresponding transitional water container when the buffered water reaches a preset water level or a preset buffer amount. Therefore, impurities in the drained water can be precipitated in the buffer water container to reduce the content of the impurities flowing back to the corresponding transition water container, and the water quality in the transition water container is improved.
In addition, in order to improve the quality of the used water returned into the interim water tank for use as the drained water, in one embodiment, referring to fig. 1, the used water for delivery to the water using unit 2 is filtered and then delivered to the water using unit; and/or filtering other water drainage of each water using operation except the first water using operation drainage and then refluxing the filtered water into the corresponding transition water container. Thus, for example, the backwater filtering device 7 can filter out impurities in the water using operation discharged water, thereby improving the cleanness of the next water using. For example, the inlet water filter 8 may filter and purify the inlet water flowing into the water using unit 2 to improve the quality of the inlet water.
In addition, in the water saving and using method, for example, the water in the first transitional water container 5 may be pre-stored water or discharged by the second water using operation of the water using unit, and when the first water using operation is performed, the first transitional water container 5 is not water or the existing water amount cannot satisfy the first water using operation, the water saving and using system may be set such that the water using unit 2 can take water from the clean water container. Therefore, in the water saving and using system, in one embodiment, when there is no water or the amount of water in the transitional water container corresponding to the water using operation cannot meet the demand of the water using operation, the clean water in the clean water container 1 is delivered to the water using unit 2. Naturally, the volume of the interim water tank itself corresponding to the water-consuming operation is such that the water demand of the water-consuming unit 2 is met, i.e. the water demand of the water-consuming unit 2 is met by the water which is filled in the interim water tank. For another example, as mentioned above, the water in the second transitional water container 23 may be pre-stored water or the water unit's third-time water-using operation drain, and when the second-time water-using operation is performed, the second transitional water container 23 is empty or the existing amount of water cannot satisfy the second-time water-using operation, the water-saving system may be configured such that the water-using unit 2 can take water from the clean water container. Thus, the water demand for each water-using operation can be further satisfactorily satisfied.
In addition, in the water-saving method, the fresh water tank and the plurality of interim water tanks may be arranged in the height direction with the water using unit 2, for example, in an embodiment, the fresh water tank and the plurality of interim water tanks may be arranged above the water using unit 2, at this time, the inflow water respectively flowing from the fresh water tank and the plurality of interim water tanks to the water using unit 2 may flow downward by its own weight or may flow into the water using unit 2 by its own intake pump, and the water service drain returning to the interim water tanks may be drained into the corresponding interim water tanks by its own drain pump of the water using unit 2. Alternatively, in another embodiment, the fresh water container and the plurality of transitional water containers may be disposed below the water using unit 2, in which case, the inlet water respectively flowing from the fresh water container and the plurality of transitional water containers to the water using unit 2 may flow into the water using unit 2 by using the own inlet pump of the water using unit 2, and the working water drain returning to the transitional water containers may be drained into the corresponding transitional water containers under the own gravity or under the own drain pump of the water using unit 2.
In addition, in the water-saving and using method, the fresh water tank and the plurality of interim water tanks and the water using unit 2 may be arranged both in a height direction and in a horizontal direction, that is, in one embodiment, regardless of the arrangement of the fresh water tank and the plurality of interim water tanks and the water using unit 2, the fresh water may be purified by a separate water intake pump, and the water working drain return may be performed by a separate water return pump. In addition, in one embodiment, the water supply to each water-using work and the water discharge using the water-using work can be returned to the interim water tank for the water supply to the previous water-using work by the same water pumping unit 10. That is, the fresh water container and the plurality of interim water containers are respectively supplied with water to the water using unit 2, and the water using operation drain from the water using unit 2 to the interim water containers can be performed by the same water pumping unit 10, for example, as shown in fig. 1, the water supply waterway 3 and the water return waterway 4 include a common waterway section 9, the common waterway section 9 is provided with the water pumping unit 10, and the water pumping unit 10 is used for supplying water to each water using operation and for enabling the water using operation drain to flow back to the interim water containers for supplying water to the previous water using operation. Thus, when the water using unit 2 is filled, the water pumping unit 10 is activated to pump the water in the fresh water container and the plurality of interim water containers into the water using unit 2 according to the demand of the water using operation. After the water using operation is finished, the water pumping unit 10 is started, and the drainage water of each water using operation of the water using unit 2 can be pumped into the corresponding transitional water container. Thus, the structure of the water saving and using system can be simplified and the cost can be reduced by the same water pumping unit 10.
In addition, the water saving and using method can be applied to various water using occasions, such as clothes washing or other washing, as long as the water discharged by the water using operation at the next time can be reused. For example, in one embodiment, as shown in fig. 1, the number of the transient water containers is two, and the water using unit 2 is a laundry washing apparatus capable of performing a triple-use operation, wherein the water saving use method is a laundry washing method, wherein the first use operation is a main washing operation, such as a washing operation, the second use operation is a first rinsing operation, and the third use operation is a second rinsing operation. Therefore, under the condition of limited clear water supply and sewage treatment capacity, the times of washing the clothes can be effectively increased, less sewage is discharged when a whole clothes washing operation program is completed, the water-saving effect is improved, the volume of the sewage tank can be correspondingly reduced, and the volume of the clear water container is correspondingly increased.
Furthermore, the present invention provides a washing vehicle, such as a laundry washing vehicle, comprising a water saving water system as described in any of the above; alternatively, the washing vehicle can implement any of the above water-saving and water-consuming methods.
In addition, the water saving system or the water saving method may also be applied to other types of water saving vehicles, such as material washing vehicles.
