Summary of the Invention
Problems to be Solved by the Invention
[0004] In the method described in Patent Document 1, no consideration is given to the conservation of water resources used for washing. Also, since alkaline ion water is more expensive than tap water, there is a situation where it is required to reduce the cost of each washing.
[0005] The present invention has been made in view of the above situation, and an object thereof is to provide a washing system capable of reducing the cost of washing laundry.
Means for Solving the Problems
[0006] A washing system according to a first aspect of the present invention is characterized by comprising: a washing tub for washing clothes using washing water; a washing water tank; a washing water supply means for supplying washing water to the washing water tank; an alkaline ionized water supply means for supplying alkaline ionized water to the washing water tank to mix the alkaline ionized water with the washing water stored in the washing water tank; a first washing water circulation path for supplying the washing water stored in the washing water tank to the washing tub; and a second washing water circulation path for sending the washing water used by the washing tub for washing back to the washing water tank.
[0007] A washing system according to a second aspect of the present invention is characterized by comprising: a washing tub for washing clothes using wash water; a wash water tank; a wash water supply means for supplying wash water stored in a first bottle to the wash water tank; an alkaline ionized water supply means for supplying alkaline ionized water stored in a second bottle to the wash water tank to mix the alkaline ionized water with the wash water stored in the wash water tank; a first wash water circulation path for supplying wash water stored in the wash water tank to the washing tub; and a second wash water circulation path for sending the wash water used by the washing tub for washing back to the wash water tank.
[0008] Preferably, the washing system further comprises a filtration device provided in the second washing water circulation path, which removes solid matter contained in the washing water used by the washing tub for washing.
[0009] As a result, the wash water discharged from the washing tub after washing is stored in a wash water tank via a second wash water circulation path, and can be reused in the washing process of another load of laundry by being supplied back into the washing tub via the first wash water circulation path, thereby reducing the cost of washing laundry.

Mode for Carrying Out the Invention
[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The same components are denoted by the same reference numerals throughout the drawings, and redundant descriptions are omitted.
[0013] <First Embodiment> The first embodiment is a washing system that circulates the rinse drainage discharged in the rinse step and reuses it in the washing step in a washing system.
[0014] FIG. 1 is an explanatory diagram showing an overview of the processing of a washing system 1 according to the first embodiment.
[0015] The washing system 1 in FIG. 1 includes a washing machine 2, a septic tank 32, a rinse water circulation path 3, a circulated water tank 34, and an ion stock solution tank 5. Further, the washing system 1 may include drainage equipment 4 as ancillary equipment. [[ID=S]]
[0016] In Figure 1, washing machine 2 is shown as a drum-type washing machine (Big Drum), but a twin-tub washing machine (a washing machine with a separate washing tub 21 (see Figure 2) and a spin-drying tub) or a top-loading washing machine (Beat Wash type washing machine) may also be used.
[0017] Furthermore, although Figure 1 shows two washing machines 2, this is for convenience to distinguish between the washing and rinsing processes. In reality, as shown in Figure 2 later, one washing machine performs both the washing and rinsing processes.
[0018] Furthermore, while this embodiment describes an example in which alkaline ionized water is used as the washing water, it is not limited to alkaline ionized water as long as it is suitable for performing the washing and rinsing processes by circulating the washing or rinsing wastewater.
[0019] Preferably, alkaline ionized water containing hydroxide ions is used as the wash water. This eliminates the concern that metal ions will remain on the laundry after the hydroxide ions remaining on the laundry evaporate easily, compared to washing with alkaline ionized water containing metal ions, such as sodium ions. Therefore, even if the rinsing step is omitted in other embodiments described later (the washing and rinsing steps are combined), there is no concern that metal ions will remain on the laundry.
[0020] Washing water is poured into the washing machine 2, which is prepared by mixing circulating water stored in the circulating water tank 34 with concentrated alkaline ionized water supplied from the ion concentrate tank 5 as needed, and adjusting it to a predetermined concentration, for example, pH 11.5. Then, the washing machine 2 performs the washing process. The washing wastewater is discharged into the drainage facility 4.
[0021] The drainage system 4 may be a drainage tank for temporarily storing wastewater or sprinklers installed on the cultivated land. The laundry wastewater stored in the drainage tank may be poured into a water truck and sprayed onto the cultivated land. Laundry wastewater is alkaline ionized water with a pH of about 11.5, and the dirt dissolved in the washing process consists of biodegradable impurities such as food scraps and sebum, so spraying laundry wastewater onto the cultivated land can improve the soil and provide additional fertilizer.
[0022] Once the washing cycle is complete, tap water (pH approximately 7) is poured into washing machine 2 from tap water 6. Then washing machine 2 performs the rinsing cycle.
[0023] When the rinsing process is complete, the rinse wastewater is discharged. The rinse wastewater is supplied to the septic tank 32. The rinse wastewater, purified in the septic tank 32, is temporarily stored in the circulating water tank 34 via the rinse water circulation path 3 and then poured back into the washing machine 2. If the concentration of alkaline ionized water is low, raw alkaline ionized water is supplied from the ion concentrate tank 5 as needed, mixed with the circulating water, and then poured into the washing machine 2.
[0024] For disinfection or sterilization of the circulating water stored in the circulating water tank 34, ultraviolet irradiation devices such as violet ultraviolet irradiation lamps or ultraviolet LEDs may be installed inside the circulating water tank 34, along the path of the rinse water circulation path 3, or at the connection point between the rinse water circulation path 3 and the circulating water tank 34.
[0025] Figure 2 is a block diagram showing the configuration of the washing system 1 according to the first embodiment.
[0026] As shown in Figure 2, the washing machine 2 comprises a washing tub 21, a processor 22, and an operation panel 23.
[0027] A drain channel 41 is connected to the washing tub 21.
[0028] The drain channel 41 is a channel that guides the wastewater from the washing tub 21 to the drainage facility 4.
[0029] A drain valve 41v (normally "closed") is provided on the drain channel 41. The drain valve 41v opens and closes the washing machine drain according to a control signal from the processor 22. Instead of the drain valve 41v, a drain cover that opens and closes the drain port of the washing tub 21 may be provided.
[0030] The processor 22 is electrically connected to the control panel 23 and, upon receiving the input "start washing" from the control panel 23, begins overall control of the washing system 1.
[0031] The rinse water circulation path 3 is configured to include an upstream circulation path 31, a septic tank 32, a downstream circulation path 33, a circulating water tank 34, and a circulating water supply path 35, all along the flow of laundry wastewater.
[0032] The upstream circulation path 31 is a channel that guides the wastewater from the washing tub 21 to the septic tank 32.
[0033] An upstream on-off valve 31v (normally "closed") is provided on the upstream circulation path 31. The upstream on-off valve 31v opens and closes according to a control signal from the processor 22.
[0034] The septic tank 32 includes a filter 321, a sedimentation tank 322, a supernatant storage tank 323, a drain outlet 324, a lower partition wall 325, and an upper partition wall 326.
[0035] The filter 321 is a device that removes solid matter contained in the wastewater flowing in from the upstream circulation path 31.
[0036] The sedimentation tank 322 is a tank in which solid matter that could not be removed by the filter 321 is allowed to settle.
[0037] The supernatant storage tank 323 is a tank for storing the supernatant liquid from the sedimentation tank 322. Within the supernatant storage tank 323, the lower partition wall 325 and the upper partition wall 326 create an upward water flow from the sedimentation tank 322, a downward water flow is formed along the upper partition wall 326, and then an upward water flow is formed towards the drain outlet 324. This promotes convection within the supernatant storage tank 323.
[0038] A septic tank pump 33P is installed near the drain outlet 324, and it discharges the purified laundry wastewater (hereinafter referred to as "circulated water") from the drain outlet 324 towards the downstream circulation path 33.
[0039] The septic tank pump 33P operates based on control signals from the processor 22.
[0040] The downstream circulation path 33 is a flow path that guides the circulating water discharged from the drain outlet 324 of the septic tank 32 to the circulating water tank 34.
[0041] The circulating water flows through the downstream circulation channel 33 and is temporarily stored in the circulating water tank 34.
[0042] The circulating water tank 34 is equipped with a concentration meter 341 and a remaining volume meter 342. The detection results from the concentration meter 341 and the remaining volume meter 342 are transmitted to the processor 22.
[0043] The circulating water supply channel 35 is a channel that guides the circulating water supplied from the circulating water tank 34 to the washing tub 21.
[0044] A circulating water supply valve 35v (normally "closed") is provided on the circulating water supply channel 35. The circulating water supply valve 35v opens and closes according to a control signal from the processor 22.
[0045] Ion concentrate tank 5 stores concentrated alkaline ionized water.
[0046] The ion concentrate supply channel 51 is a channel that guides alkaline ionized water supplied from the ion concentrate tank 5 to the circulating water supply channel 35.
[0047] An ionized water supply valve 51v (normally "closed") is provided on the ionized concentrate supply path 51. The ionized water supply valve 51v opens and closes according to a control signal from the processor 22.
[0048] The water supply channel 61 is a channel that guides tap water from the water supply 6 to the washing machine tub 21.
[0049] A water supply valve 61v (normally "closed") is provided on the water supply channel 61. The water supply valve 61v opens and closes according to a control signal from the processor 22.
[0050] Figure 3 is a flowchart showing the processing flow of the laundry system 1 according to the first embodiment.
[0051] When the user presses the "Start Washing" button on the control panel 23 (S01), the processor 22 outputs an "open" signal to the circulating water supply valve 35v and the ionized water supply valve 51v, and circulating water is supplied to the washing tub 21. After the water is supplied, the processor 22 outputs a "closed" signal to the circulating water supply valve 35v and the ionized water supply valve 51v (S02). At this time, the processor 22 may acquire the value from the concentration meter 341 and adjust the pH of the washing water by determining the time to keep the ionized water supply valve 51v "open".
[0052] The washing tub 21 rotates and the washing process is executed (S03).
[0053] When the washing cycle is complete, the processor 22 outputs an "open" signal to the drain valve 41v, and the washing wastewater is discharged. After draining, the processor 22 outputs a "closed" signal to the drain valve 41v (S04).
[0054] When draining is complete, the processor 22 outputs an "open" signal to the tap water supply valve 61v, and tap water is supplied to the washing tub 21. After the water is supplied, the processor 22 outputs a "closed" signal to the tap water supply valve 61v (S05).
[0055] The washing tub 21 rotates and the rinsing process is performed (S06).
[0056] When the rinsing process is complete, the processor 22 outputs an "open" signal to the upstream valve 31v, and the rinse wastewater is supplied to the septic tank 32. After draining, the processor 22 outputs a "closed" signal to the upstream valve 31v (S07). The rinse wastewater is purified as it passes through the septic tank 32, and circulating water is generated.
[0057] Based on the detection result of the remaining amount gauge 342, the processor 22 determines whether or not to supply circulating water to the circulating water tank 34. If it is "necessary" (S08:Yes), the processor 22 outputs an "operation signal" to the septic tank pump 33P. The septic tank pump 33P discharges circulating water into the downstream circulation path 33 and supplies it to the circulating water tank 34. When the capacity of the circulating water tank 34 is filled, the processor 22 outputs a "stop signal" to the septic tank pump 33P (S09). If it is "not" (S08:No), the process ends.
[0058] The washing system 1 according to the first embodiment comprises a washing machine 2 and a rinse water circulation path 3, wherein the washing machine 2 includes a washing tub 21 that is supplied with alkaline ionized water for washing, the washing tub 21 performs a washing process and a rinsing process, and the rinse wastewater discharged in the rinsing process is supplied to the washing tub 21 via the rinse water circulation path 3 and reused in the washing process.
[0059] According to the washing system 1 of the first embodiment, the rinse wastewater generated in the rinsing process can be reused in the next washing process, thus saving water resources.
[0060] Preferably, a septic tank 32 is provided on the circulation path.
[0061] This allows the circulating water, purified by removing fixed particles from the rinse wastewater and allowing impurities to settle, to be reused in a new washing process.
[0062] <Second Embodiment> The second embodiment is a laundry system in which the laundry wastewater (reusable alkaline ionized water) discharged during the laundry process is circulated and reused in the laundry process. In the description of the second embodiment, components that overlap with those of the first embodiment are denoted by the same reference numerals, and redundant explanations are omitted.
[0063] Figure 4 is an explanatory diagram showing an overview of the processing of the washing system 1a according to the second embodiment.
[0064] The washing system 1a in Figure 4 comprises a washing machine 2, a septic tank 32, a washing water circulation path 3a, a circulating water tank 34, and an ion concentrate tank 5. The washing system 1 may also be equipped with a drainage system 4 as an ancillary facility.
[0065] In Figure 4, two washing machines 2 are shown, but this is for convenience to distinguish between the washing and rinsing processes. In reality, one washing machine 2 performs both the washing and rinsing processes.
[0066] The washing machine 2 is supplied with circulating water (reusable alkaline ionized water; the circulating water tank is equivalent to the washing water tank) stored in the circulating water tank 34. If the amount of washing wastewater in the circulating water tank 34 is insufficient, alkaline ionized water adjusted to a predetermined concentration, for example, pH 11.5, is supplied to the circulating water tank 34 from the ion concentrate tank 5 as needed. The washing machine 2 then performs the washing process. The washing wastewater is supplied to the septic tank 32. The washing wastewater, purified in the septic tank 32, is temporarily stored in the circulating water tank 34 via the washing water circulation path 3a and then poured back into the washing machine 2.
[0067] Once the washing cycle is complete, tap water (pH approximately 7) is poured into washing machine 2 from tap water 6. Then washing machine 2 performs the rinsing cycle.
[0068] Once the rinsing process is complete, the rinse wastewater is discharged into the drainage facility 4.
[0069] Figure 5 is a block diagram showing the configuration of the washing system 1a according to the second embodiment.
[0070] The difference from the washing system 1 according to the first embodiment is that, instead of the ion concentrate tank 5, it is equipped with an ion water tank 5a that stores pH-adjusted ion water, and the ion water is supplied via an ion water supply passage 51a. The ion water tank 5a stores alkaline ion water that is close to a predetermined concentration (for example, pH 11.5).
[0071] Therefore, the rinse water circulation path 3 of the first embodiment differs in that it stores raw alkaline ionized water (for example, pH 12 or higher) in the ion stock tank 5 and circulates the reused rinse wastewater to dilute the raw alkaline ionized water.
[0072] In a configuration where the raw alkaline ionized water is diluted by using the ionized water tank 5a instead of the ionized water stock tank 5, there is a possibility that reaction heat will be generated during dilution, requiring countermeasures. However, according to this embodiment, the ionized water tank 5a can store alkaline ionized water that can be used directly as laundry water, so the above countermeasures become unnecessary.
[0073] Therefore, in the second embodiment, the concentration meter 341 is not essential, and the ion water supply valve 51v can be opened and closed according to the remaining amount in the circulating water tank 34.
[0074] Figure 5 illustrates a suitable example configuration in which a concentration meter 341 is installed in the circulating water tank 34 to monitor the concentration of the circulating water in the tank 34.
[0075] The other components are the same as in the first embodiment, so a redundant explanation will be omitted.
[0076] Figure 6 is a flowchart showing the processing flow of the washing system 1a according to the second embodiment. Repeated explanations of steps identical to those in the first embodiment are omitted.
[0077] The difference from the processing flow of the washing system 1 according to the first embodiment is that in step S02, the processor 22 outputs an "open" signal to the circulating water supply valve 35v, but does not output an "open" signal to the ionized water supply valve 51v. When the supply of circulating water (reused alkaline ionized water) to the washing tub 21 is complete, the processor 22 outputs a "closed" signal to the circulating water supply valve 35v (S021).
[0078] Furthermore, when the washing process (S03) is completed, the processor 22 outputs an "open" signal to the upstream on-off valve 31v, and the washing wastewater is supplied to the septic tank 32. After drainage, the processor 22 outputs a "closed" signal to the upstream on-off valve 31v (S041). The washing wastewater is purified as it passes through the septic tank 32, and circulating water is generated.
[0079] Furthermore, after supplying tap water (S05) and the rinsing process is completed (S06), the processor 22 outputs an "open" signal to the drain valve 41v, and the rinse wastewater is discharged. After draining, the processor 22 outputs a "close" signal to the drain valve 41v (S071).
[0080] Based on the detection result of the remaining amount gauge 342, the processor 22 determines whether or not to supply alkaline ionized water to the circulating water tank 34. If it is "necessary" (S08: Yes), the processor 22 outputs an "operate" signal to the septic tank pump 33P. The septic tank pump 33P discharges circulating water into the downstream circulation path 33 and supplies it to the circulating water tank 34. If this is still insufficient, it outputs an "open" signal to the ionized water supply valve 51v and replenishes the circulating water tank 34 with alkaline ionized water. Once replenishment is complete, it outputs a "close" signal to the ionized water supply valve 51v (S091).
[0081] The washing system 1a according to the second embodiment comprises a washing machine 2 and a washing water circulation path 3a, wherein the washing machine 2 includes a washing tub 21 that is supplied with alkaline ionized water for washing, the washing tub 21 performs a washing process and a rinsing process, and the washing wastewater discharged in the washing process is supplied to the washing tub 21 via the washing water circulation path 3a and reused in the washing process.
[0082] According to the washing system 1a of the second embodiment, the wastewater generated in the washing process can be reused in the next washing process. This allows washing to be performed while saving relatively expensive alkaline ionized water.
[0083] Preferably, a septic tank 32 is provided on the circulation path.
[0084] This allows the circulating water, purified by removing fixed deposits from the laundry wastewater and allowing impurities to settle, to be reused in a new washing process.
[0085] <Third Embodiment> The third embodiment is a laundry system in which the laundry wastewater (reusable alkaline ionized water) discharged in the washing process is circulated and reused in the washing process, and the rinse wastewater discharged in the rinsing process is circulated and reused in the rinsing process. In the description of the third embodiment, the same reference numerals are used for components that overlap with the first and second embodiments, and redundant explanations are omitted.
[0086] Figure 7 is an explanatory diagram showing an overview of the processing of the washing system 1b according to the third embodiment.
[0087] In the washing system 1b shown in Figure 7, a washing water circulation path 3a is connected to the washing machine 2, and a rinse water circulation path 3b is also connected to it.
[0088] In Figure 7, two washing machines 2 are shown, but this is for convenience to distinguish between the washing and rinsing processes. In reality, one washing machine 2 performs both the washing and rinsing processes.
[0089] The washing water circulation path 3a has the same configuration as in the second embodiment, so its explanation will be omitted.
[0090] The rinse water circulation path 3b differs from the rinse water circulation path 3 of the first embodiment in that a circulating water tank 34b is added on top of the rinse water circulation path 3, and the downstream end of the circulating water tank 34b is connected to the washing tub 21.
[0091] Figure 8 is a block diagram showing the configuration of the washing system 1b according to the third embodiment. Each component on the rinse water circulation path 3b shown in Figure 8 is the same as the components on the rinse water circulation path 3, but in order to distinguish them from the components on the washing water circulation path 3a, the reference numerals for each component on the rinse water circulation path 3b in Figure 8 are shown with the subscript "b" added to the reference numerals of the components on the rinse water circulation path 3.
[0092] In the washing water circulation path 3a, the washing wastewater is purified in the septic tank 32 and supplied to the circulating water tank 34. This water is then supplied to the washing tub 21 during the washing process. The circulating water for washing that flows through the washing water circulation path 3a is alkaline ionized water with a pH of approximately 11.5.
[0093] The rinse water circulation path 3b supplies rinse wastewater to a circulating water tank 34b where it has been purified in the septic tank 32b, and then supplies it to the washing tub 21 during the rinsing process. The circulating water for rinsing that circulates through the rinse water circulation path 3b has a pH of approximately 7.0.
[0094] Figure 9 is a flowchart showing the processing flow of the washing system 1b according to the third embodiment. Steps identical to those in the first and second embodiments will not be explained again.
[0095] When the "Start Washing" button is pressed in step S01 (S01), the processor 22 outputs an "open" signal to the circulating water supply valve 35v located on the washing water circulation path 3a. Once the circulating water (recycled alkaline ionized water) has finished being supplied to the washing tub 21, the processor 22 outputs a "closed" signal to the circulating water supply valve 35v (S021).
[0096] The washing process is executed (S03), and upon completion, the processor 22 outputs an "open" signal to the upstream valve 31v, and the washing wastewater is supplied to the septic tank 32. After drainage, the processor 22 outputs a "closed" signal to the upstream valve 31v (S041). The washing wastewater is purified as it passes through the septic tank 32, and circulating water is generated.
[0097] As preparation for the rinsing process, an "open" signal is output to the circulating water supply valve 35vb located on the rinse water circulation path 3b, supplying circulating water for rinsing to the washing tub 21. After supplying the water, a "closed" signal is output to the circulating water supply valve 35vb (S052).
[0098] The washing tub 21 rotates and the rinsing process is performed (S06). When it finishes, the processor 22 outputs an "open" signal to the upstream on-off valve 31vb, and the rinse wastewater is supplied to the septic tank 32b. After draining, the processor 22 outputs a "closed" signal to the upstream on-off valve 31vb (S072). The washing wastewater is purified as it passes through the septic tank 32b, and circulating water is generated.
[0099] The processor 22 determines whether replenishment is necessary for each circulating water tank 34 and 34b, based on the detection results of the remaining water meters 342 and 342b located in the circulating water tank 34 for storing washing water and the circulating water tank 34b for storing rinsing water, respectively. If replenishment is necessary (S08:Yes), the processor 22 outputs an "operate" signal to the septic tank pumps 33P and 33Pb and an "open" signal to the ionized water supply valve 51v as appropriate, and performs replenishment. After replenishment, the processor 22 outputs a "stop" signal to the septic tank pumps 33P and 33Pb and a "close" signal to the ionized water supply valve 51v (S092). If replenishment is not necessary after that, or in step S08 (S08:No), the process ends.
[0100] The washing system 1b according to the third embodiment comprises a washing tub 21, a washing water circulation path 3a, and a rinse water circulation path 3b, wherein the washing machine 2 includes a washing tub 21 that is supplied with alkaline ionized water to perform washing, the washing tub 21 performs a washing process and a rinsing process, the washing wastewater discharged in the washing process is supplied to the washing tub 21 via the washing water circulation path and reused in the washing process, and the rinse wastewater discharged in the rinsing process is supplied to the washing tub 21 via the rinse water circulation path 3b and reused in the rinsing process.
[0101] According to the third embodiment of the washing system 1b, the washing wastewater generated in the washing process can be reused in the next washing process, and the rinsing wastewater generated in the rinsing process can be reused in the next rinsing process. This allows for rinsing while saving relatively expensive alkaline ionized water and tap water.
[0102] Furthermore, according to the washing system 1b of the third embodiment, since washing wastewater and rinsing wastewater are not discharged from the washing system 1b, wastewater treatment is unnecessary, thereby reducing the environmental burden.
[0103] <Fourth Embodiment> The fourth embodiment is a washing system in which, in a single washing machine, the washing wastewater is circulated as washing water, and the rinse wastewater is circulated as rinse water. In the description of the fourth embodiment, components that overlap with those of the first to third embodiments are denoted by the same reference numerals, and redundant explanations are omitted.
[0104] Figure 10 is a schematic diagram of the laundry system 1c according to the fourth embodiment.
[0105] The washing system 1c according to the fourth embodiment is implemented (equipped) in a washing machine 102. The washing machine 102 comprises a washing tub 121 and a bottle cartridge 130.
[0106] The bottle cartridge 130 is detachably attached to the washing machine 102.
[0107] The bottle cartridge 130 includes an ionized water bottle 131 that contains alkaline ionized water (pH approximately 11.5) and a rinse water bottle 132 that contains tap water for rinsing (pH approximately 7.0).
[0108] The washing machine 102 includes a washing tub 121, a processor 122, an operation panel 123, a washing water circulation path 141, and a rinse water circulation path 142.
[0109] The washing water circulation path 141 connects the ionized water bottle 131 and the washing tub 121.
[0110] A first pump 141p is provided on the washing water circulation path 141.
[0111] The washing tub 121 is equipped with a first drain valve 141v and a first filter 141f at its bottom.
[0112] The rinse water circulation path 142 connects the rinse water bottle 132 to the washing tub 121.
[0113] A second pump 142p is provided on the rinse water circulation path 142.
[0114] The bottom of the washing tub 121 is equipped with a second drain valve 142v and a second filter 142f.
[0115] The processor 122 executes the washing and rinsing processes according to the "start washing" signal from the control panel 123.
[0116] The processor 122 controls the opening and closing of the first pump 141p, the second pump 142p, the first drain valve 141v, and the second drain valve 142v.
[0117] Figure 11 is a flowchart showing the processing flow of the laundry system 1c according to the fourth embodiment.
[0118] When the user presses the "Start Washing" button on the control panel 123 (S101), the processor 122 outputs an "Operate" signal to the first pump 141p on the washing water circulation path 141, and ionized water is supplied from the ionized water bottle 131 to the washing tub 121. After the water is supplied, the processor 122 outputs a "Stop" signal to the first pump 141p (S102).
[0119] The washing tub 21 rotates and the washing process is executed (S103).
[0120] When the washing process is complete, the processor 122 outputs an "open" signal to the first drain valve 141v on the washing water circulation path 141, and the washing wastewater is discharged. The washing wastewater passes through the first filter 141f and is collected into the ionized water bottle 131. After draining, a "closed" signal is output to the first drain valve 141v (S104).
[0121] When the process transitions to the rinsing stage, the processor 122 outputs an "operate" signal to the second pump 142p on the rinse water circulation path 142, and rinse water is supplied from the rinse water bottle 132 to the washing tub 121. After the water is supplied, the processor 122 outputs a "stop" signal to the first pump 141p (S105).
[0122] The washing tub 21 rotates and the rinsing process is performed (S106).
[0123] When the rinsing process is complete, the processor 122 outputs an "open" signal to the second drain valve 142v on the rinse water circulation path 142, and the rinse wastewater is discharged. The rinse wastewater passes through the second filter 142f and is collected in the rinse water bottle 132. After draining, a "closed" signal is output to the second drain valve 142v (S107).
[0124] If bottle cartridge 130 needs to be replaced (S108:Yes), replace bottle cartridge 130 (S109). After that, or if replacement is "not necessary" (S108:No), terminate the process.
[0125] The washing system 1c according to the fourth embodiment comprises a washing machine 102, a bottle cartridge 130, a washing water circulation path 141, and a rinse water circulation path 142. The washing machine 2 includes a washing tub 121 that is supplied with alkaline ionized water to perform washing. The washing tub 121 performs a washing process and a rinsing process. The bottle cartridge 130 includes an ionized water bottle 131 that contains the alkaline ionized water and a rinse water bottle 132 that contains the rinse water. In the washing process, the alkaline ionized water supplied from the ionized water bottle 131 is supplied to the washing tub 121 via the washing water circulation path 141. The washing wastewater discharged in the washing process is collected in the ionized water bottle 131. In the rinsing process, the rinse water supplied from the rinse water bottle 132 is supplied to the washing tub 121 via the rinse water circulation path 142. The rinse wastewater discharged in the rinsing process is collected in the rinse water bottle 132.
[0126] According to the washing machine 102 implementing the washing system 1c of the fourth embodiment, the washing wastewater generated in the washing process can be reused in the next washing process, and the rinsing wastewater generated in the rinsing process can be reused in the next rinsing process. This allows for rinsing while saving relatively expensive alkaline ionized water and tap water.
[0127] Furthermore, the ionized water bottle 131 and the rinse water bottle 132 are housed in the bottle cartridge 130, and the alkaline ionized water and rinse water can be replenished by replacing the bottle cartridge 130. In conventional washing machines, it was necessary to have a water tap for water supply, to add detergent, and to place the washing machine on a waterproof tray and connect a drain hose to the drain. However, in this embodiment, the circulation path for wash water and rinse water is closed between the washing machine 102 and the bottle cartridge 130, so there is no need for a water tap or drain at the location where the washing machine 102 is placed. Thus, the flexibility of where the washing machine 102 can be placed is increased.
[0128] Furthermore, the system may be configured to allow replacement of only the ionized water bottle 131 or only the rinse water bottle 132, rather than replacing the bottle cartridge in units of 130.
[0129] <Fifth Embodiment> The fifth embodiment is an embodiment in which, when washing and rinsing using alkaline ionized water circulated in a washing machine equipped with a dryer, the water generated when the dryer performs the drying process is used in the washing or rinsing process. More specifically, it is an embodiment in which the water attached to the heat exchanger in the part that heats the compressed refrigerant when the heat pump installed in the dryer generates hot air for drying is used as replenishment water. In the description of the fifth embodiment, the same reference numerals are used for components that overlap with the first to fourth embodiments, and redundant explanations are omitted.
[0130] Figure 12 is a schematic diagram of the laundry system 1d according to the fifth embodiment.
[0131] The washing system 1d according to the fifth embodiment is implemented in a washing machine 200 equipped with a dryer 250.
[0132] The washing machine 200 mainly comprises a washing tub 121, a processor 122, a control panel 123, a washing water circulation path 141, a rinse water circulation path 142, a replenishment water path 252, a washing pan 230, and a dryer 250.
[0133] The washing machine pan 230 includes an ionized water tank 231 for storing alkaline ionized water (pH approximately 11.5) and a rinse water tank 232 for storing tap water for rinsing (pH approximately 7.0).
[0134] In the washing water circulation path 141, alkaline ionized water (washing water) stored in the ionized water tank 231 is drawn up by the first pump 141p and supplied to the washing tub 121.
[0135] The alkaline ionized water used in the washing process flows into the ionized water tank 231 after the washing process is completed, passing through the first drain valve 141v and the first filter 141f at the bottom of the washing tub 121.
[0136] The dryer 250 is equipped with a discharge mechanism 251 that discharges water generated when drying laundry to the outside of the dryer 250.
[0137] The replenishment water channel 252 connects the discharge mechanism 251 and the rinse water tank 232. When the drying process is performed in the dryer 250, the water discharged is supplied to the rinse water tank 232 via the replenishment water channel 252. By replenishing the rinse water tank 232 with the water discharged in the drying process, rinse water can be generated and replenished in the washing machine 200.
[0138] On the rinse water circulation path 142, the rinse water tank 232, the second pump 142p, the pre-filter tank 235, and the filter 233 are arranged from upstream to downstream.
[0139] Since the water flow velocity through filter 233 is slower than the water flow velocity through rinse water circulation path 142, the water is temporarily stored in pre-filter tank 235 before passing through filter 233. In other words, pre-filter tank 235 functions as a buffer.
[0140] The filter-pre-tank 235 is equipped with an ultraviolet LED 234 for sterilization or disinfection.
[0141] The rinse water is drawn from the rinse water tank 232 by the second pump 142p, temporarily stored in the pre-filter tank 235, and sterilized by ultraviolet light. Then it is filtered by the filter 233 and flows into the washing tub 121.
[0142] After the rinsing process is complete, the rinse water in the washing tub 121 passes through the second drain valve 142v and the second filter 142f at the bottom of the washing tub 121 and flows into the rinse water tank 232.
[0143] According to the washing machine 200 implementing the washing system 1d of the fifth embodiment, the water generated in the drying process in the dryer 250 is supplied to the rinse water tank 232. As a result, if there is a sufficient amount of drainage from the dryer 250, it is not necessary to supply water from outside the washing machine 200, or the frequency of such supply can be reduced.
[0144] In particular, the reuse of wastewater from the dryer 250 makes it easier to do laundry using the washing machine 200, even in environments where it is difficult to secure fresh water.
[0145] Furthermore, while the high pH of the wash water suppresses the growth of bacteria, the neutral pH of the rinse water raises concerns about bacterial growth. In this regard, sterilization treatment with ultraviolet LED 234 can keep the rinse water clean. As a result, it also contributes to the cleanliness of the washing tub 121, the rinse water tank 232, and the rinse water circulation path 142.
[0146] Furthermore, similar to the fourth embodiment, the wastewater generated in the washing process can be reused in the next washing process, and the wastewater generated in the rinsing process can be reused in the next rinsing process. This allows for rinsing while saving relatively expensive alkaline ionized water and tap water.
[0147] Furthermore, according to this embodiment, since the circulation path for wash water and rinse water is closed between the washing machine 200 and the washing pan 230, there is no need for a water supply or drain outlet at the location where the washing machine 200 is placed. Therefore, the degree of freedom in the placement of the washing machine 200 can be increased.
[0148] In the above explanation, the water generated from the dryer 250 is reused in the rinsing process, but it may also be supplied to the ionized water tank 231 via the replenishment water channel 252. In that case, since a decrease in pH is expected due to the water supply, alkaline ionized water concentrate should be supplied as needed.
[0149] <Sixth Embodiment> The sixth embodiment is an embodiment in which a water generator that generates water from water vapor in the air is installed in a washing machine, and when washing and rinsing is performed by circulating alkaline ionized water, the generated water is used in the washing or rinsing process. More specifically, the water generator is an embodiment in which water is generated from air using air conditioning equipment including a peat pump, heat exchanger, and refrigerant, and used as replenishment water. In the description of the sixth embodiment, the same reference numerals are used for components that overlap with the first to fifth embodiments, and redundant explanations are omitted.
[0150] Figure 13 is a schematic diagram of the laundry system 1e according to the sixth embodiment.
[0151] The washing system 1e according to the sixth embodiment is implemented in a washing machine 260 equipped with a water generating device 261 including a heat pump, a heat exchanger, and a refrigerant.
[0152] The washing machine 260 also includes a washing tub 121, a processor 122, an operation panel 123, a washing water circulation path 141, a first pump 141p, a first drain valve 141v, a first filter 141f, a washing pan 230, an ion water tank 231, a concentration meter 341, a replenishment water path 252, a water generator 261, an ion concentrate tank 5, and an ion concentrate supply path 51.
[0153] The water generator 261 generates water from water vapor contained in the atmosphere by performing a dehumidification process and supplies it to the ionized water tank 231.
[0154] The processor 122 monitors the concentration of alkaline ionized water stored in the ionized water tank 231, as detected by the concentration meter 341, to ensure that it does not fall below a predetermined concentration.
[0155] When the processor 122 determines that the concentration has fallen below a predetermined level, it supplies the ion concentrate to the ion water tank 231. This ensures that even if the concentration of alkaline ion water in the ion water tank 231 decreases due to water supply from the water generator 261, the pH is maintained at a predetermined level, preserving the cleaning power and sterilization power of the wash water.
[0156] The washing machine 260 is characterized by having a washing water circulation path 141 but not a rinse water circulation path 142. It performs the washing and rinsing processes using only alkaline ionized water. In this case, after the washing process is completed, the water is drained into the ionized water tank 231, and alkaline ionized water may be poured back into the washing tub 121 via the washing water circulation path 141 for the rinsing process.
[0157] Alternatively, alkaline ionized water may be poured into the washing tub 121 once, the washing tub 121 may be rotated, and the water may be drained into the ionized water tank 231 to serve as both the washing and rinsing cycles.
[0158] According to the washing machine 260 implementing the washing system 1e of the sixth embodiment, the water generator 261 generates water from the atmosphere and supplies it to the ionized water tank 231. This makes it easier to do laundry using the washing machine 260 even in environments where it is difficult to secure fresh water.
[0159] Furthermore, since no wastewater is discharged from the washing machine 260, the environmental burden can be reduced. In particular, environmental pollution caused by microplastics being discharged into rivers and the sea from washing wastewater and rinse water can be prevented or reduced. Microplastics contained in the washing water and rinse water may be collected by installing a filter that filters out microplastics in the circulation path, thereby preventing or reducing their release into the environment.
[0160] Furthermore, when alkaline ionized water containing hydroxide ions is used, the alkaline ionized water adhering to the laundry evaporates along with the moisture during the drying process. Therefore, rinsing with fresh water becomes unnecessary, allowing the washing and rinsing processes to be combined, contributing to a reduction in the time and electricity required for laundry.
[0161] Furthermore, according to this embodiment, since the circulation path of alkaline ionized water is closed within the washing machine 260, there is no need for a water supply or drain outlet at the location where the washing machine 260 is placed. Therefore, the degree of freedom in the placement of the washing machine 260 can be increased.
[0162] In the above description, the water produced by the water generator 261 was supplied to the ionized water tank 231. However, in a washing machine equipped with a rinse water tank 232 (for example, the washing machine 200 according to the fifth embodiment), the water produced by the water generator 261 may be supplied to the rinse water tank 232. In other words, the dryer 250 is one embodiment of the water generator.
[0163] <Seventh Embodiment> The seventh embodiment is a laundry system 1f equipped with a laundry water circulation device, which, for example, connects the drain of an existing washing machine to the water inlet of the laundry water circulation device, and connects the drain of the laundry water circulation device to the water inlet of the washing machine, thereby eliminating discharge into the sewer pipe. The existing washing machine may be a commercial washing machine equipped with multiple washing tubs, such as those found in coin laundries. In this embodiment, "laundry water" refers to the total amount of water necessary for washing, including washing water and rinsing water.
[0164] Figure 14 is a schematic diagram of the laundry system 1f according to the seventh embodiment.
[0165] The washing system 1f according to the seventh embodiment is configured by connecting a washing water circulation device 400 to the washing tub 121 of an existing washing machine.
[0166] The washing water circulation device 400 comprises a washing water circulation path 405 used for reusing washing water, which is mainly alkaline ionized water, and a rinse water circulation path 415 used for reusing rinse water, which is water with a pH of around 7.0.
[0167] The first inlet 406 of the washing water circulation path 405 is connected to the first drain outlet 150 of the washing tub 121.
[0168] The first outlet 407 of the washing water circulation path 405 is connected to the first water inlet 160 of the washing tub 121.
[0169] The second inlet 416 of the rinse water circulation path 415 is connected to the second drain outlet 151 of the washing tub 121.
[0170] The second drain outlet 417 of the rinse water circulation path 415 is connected to the second water inlet 161 of the washing tub 121.
[0171] In Figure 14, for the sake of explanation, the first drain port 150 and the second drain port 151 of the washing tub 121 are shown separately. However, in reality, the openings for the first drain port 150 and the second drain port 151 can be formed as a single unit, and the washing water circulation device 400 can switch whether to circulate the water through the washing water circulation path 405 or the rinse water circulation path 415.
[0172] Similarly, in Figure 14, the first water inlet 160 and the second water inlet 111 of the washing tub 121 are distinguished for ease of explanation, but they may be formed as a single opening.
[0173] In the washing water circulation path 405, the washing temporary storage tank 401, the washing filtration standby tank 402, the first filtration device 403, and the washing storage tank 404 are arranged from upstream (first inlet 406) to downstream (first outlet 407).
[0174] In the rinse water circulation path 415, the following are arranged from upstream (second inlet 416) to downstream (second drain outlet 417): a temporary rinse storage tank 411, a rinse filtration standby tank 412, a second filtration device 413, and a rinse storage tank 414.
[0175] Furthermore, an ultraviolet LED 419 is provided on the rinse water circulation path 415. In Figure 14, it is positioned directly in front of the second drain port 417. This sterilizes the rinse water just before it is supplied to the washing tub 121, improving the hygiene of the rinse water. The ultraviolet LED 419 is a form of ultraviolet irradiation device, and may be positioned in one or more of the rinse temporary storage tank 411, rinse filtration standby tank 412, or rinse storage tank 414. Alternatively, it may be positioned along the flow path pipe of the rinse water circulation path 415, as is the case with the ultraviolet LED 419.
[0176] Using the same water for multiple washes requires high-performance filtration, which takes time. In this embodiment, the filtered wash water is stored in the washing storage tank 404, and the filtered rinse water is stored in the rinse storage tank 414 to prepare for the next wash.
[0177] As a result, high-performance filtration is performed while the water supply of wash water and rinse water to the washing tub 121 for the next wash can be carried out as before, so the time required for washing remains the same, allowing for smooth washing while enabling the repeated circulation and reuse of alkaline ionized water and rinse water.
[0178] Furthermore, as a result of the high-performance filtration, the flow velocity passing through the first filtration device 403 and the second filtration device 413 becomes slower than the flow velocity when draining the wash water and rinse water from the washing tub 121.
[0179] Therefore, by providing a washing filtration standby tank 402 and a rinsing filtration standby tank 412 immediately before the first filtration device 403 and the second filtration device 413, the water can be temporarily stored in the washing filtration standby tank 402 and the rinsing filtration standby tank 412, thereby absorbing the difference between the inflow velocity to the washing temporary storage tank 401 and the rinsing temporary storage tank 411 and the flow velocity passing through the first filtration device 403 and the second filtration device 413.
[0180] In Figure 14, a washing filtration standby tank 402 and a rinsing filtration standby tank 412 are provided, but the timing of the discharge and supply of alkaline ionized water from the washing tub 121 is different from the timing of the draining and supply of rinse water (the timings are mutually exclusive).
[0181] The washing filtration standby tank 402 and the rinsing filtration standby tank 412 function as buffers for adjusting the flow rate of the first filtration device 403 and the second filtration device 413.
[0182] Therefore, instead of having separate filtration standby tanks for washing (402) and rinsing (412), they may be configured as a single filtration standby tank (shared filtration standby tank) shared by alkaline ionized water and rinsing water, and a flow path switching valve may be provided between the shared filtration standby tank and the first filtration device (403) and the second filtration device (413).
[0183] Furthermore, if alkaline ionized water is flowing into the shared filtration standby tank, the flow path switching valve may be switched to allow it to flow into the first filtration device 403, and if rinse water is flowing into the shared filtration standby tank, the flow path switching valve may be switched to allow it to flow into the second filtration device 413.
[0184] This reduces the number of parts and thus the cost, as only one filtration standby tank is needed, and it is also expected that the washing water circulation system can be made smaller.
[0185] Furthermore, since high-performance filtration is necessary to reuse the same water for washing multiple times, and as a result, the challenge of time-consuming filtration is common to all embodiments, it is preferable to apply the configuration of providing a filtration standby tank upstream of the filtration device and filter for alkaline ionized water and rinse water to all embodiments.
[0186] As a result, in any embodiment, the same alkaline ionized water and rinse water can be recycled, and while hygiene concerns are addressed by using high-performance filtration devices and filters, the drainage rate from the washing tub 121 is controlled by storing the water in the temporary storage tank 401 for washing and the temporary storage tank 411 for rinsing. This prevents stagnation of the drainage from the washing tub 121 through high-performance filtration, allowing for smooth washing and hygienic recycling of alkaline ionized water and rinse water.
[0187] <Eighth Embodiment> The eighth embodiment is one in which the washing machine and the washing water circulation device are configured as separate units, and the washing water circulation device is connected to the washing machine to circulate and reuse alkaline ionized water and rinse water.
[0188] Figure 15 shows a washing water circulation device 400a, which houses a washing water circulation device 400 in a single enclosure, installed at the bottom of a washing machine 420. Figure 16 is an enlarged view of the washing water circulation device 400a.
[0189] It is preferable that the washing water circulation device 400a be configured to have a shape almost identical to the bottom surface of the washing machine 420 to be used, so that the washing machine 420 can be mounted on top of the washing water circulation device 400a. If the washing water circulation device 400a is connected to a household washing machine, it is preferable that the washing water circulation device 400a be configured to conform to the dimensional standards of the washing machine pan installed in the house, or to fit inside the washing machine pan, so that the washing water circulation device 400a can be installed if there is space to place the washing machine pan.
[0190] As shown in Figure 16, the washing water circulation device 400a houses a temporary storage tank 401 for washing and a temporary storage tank 411 for rinsing in a single housing 430.
[0191] Furthermore, the washing water circulation device 400a includes an inlet 431, a flow path switching device 432, an outlet 433, and a controller 450.
[0192] Inlet 431 corresponds to the configuration in the schematic diagram of Figure 14 in which the first inlet 406 and the second inlet 416 are combined into a single inlet 431. Since washing water and rinse water flow into inlet 431, a flow path switching device 432 installed downstream switches the flow path so that the washing water flows into the temporary storage tank 401 for washing, and switches the flow path so that the rinse water flows into the temporary storage tank 411 for rinsing.
[0193] The housing 430 is equipped with a first inspection port 440 that communicates with the inside of the temporary washing storage tank 401 (washing water storage chamber).
[0194] The housing 430 is also provided with a second inspection port 441 that communicates with the inside of the temporary rinsing storage tank 411 (the rinsing water storage chamber).
[0195] The first inspection port 440 and the second inspection port 441 are used for maintenance of the temporary storage tank 401 for washing and the temporary storage tank 411 for rinsing, respectively.
[0196] The first filtration device 403 and the first submersible pump 408 are housed inside the temporary storage tank 401 for washing.
[0197] The temporary rinsing storage tank 411 houses the second filtration device 413 and the second submersible pump 418.
[0198] The first filtration device 403 and the second filtration device 413 are cartridge-type filtration devices equipped with pleated filters. The first filtration device 403 filters the alkaline wash water, and the second filtration device 413 filters the rinse water.
[0199] Figure 17 is an enlarged view of the first filtration device 403.
[0200] The first filtration device 403 comprises a filter cartridge 4031, a cap 4032, and an outer casing 4033.
[0201] The filter cartridge 4031 is housed inside the outer casing 4033, with one end supported by the side wall of the housing 430, more specifically by the side wall of the temporary washing water storage tank 401, and sealed with a cap 4032. This prevents washing water from leaking out of the temporary washing water storage tank 401.
[0202] The other end of the outer casing 4033 is connected to the first submersible pump 408 by a joint member 4034. As a result, the unfiltered wash water discharged from the first submersible pump 408, i.e., the wash water stored in the temporary washing storage tank 401, is supplied to the outer surface of the filter cartridge 4031 of the first filtration device 403 via the joint member 4034. The unfiltered wash water is filtered as it permeates from the outer surface of the filter cartridge 4031 toward the center. It is then supplied to the wash water circulation path 405 connected to the center of the filter cartridge 4031 and supplied to the washing tub 121 from the outlet 433.
[0203] The second filtration device 413 has the same configuration as the first filtration device 403. The second submersible pump 418 supplies the second filtration device 413 with rinse water before filtration, i.e., rinse water stored in the temporary rinse storage tank 411. The rinse water before filtration is filtered as it permeates from the outer surface of the filter cartridge 4031 toward the center. It is then supplied to the rinse water circulation path 415 connected to the center of the filter cartridge 4031. An ultraviolet LED 419 is provided before the outlet 433 in the rinse water circulation path 415. The ultraviolet-sterilized rinse water is supplied to the washing tub 121 from the outlet 433.
[0204] Figure 18 is an electrical diagram of the washing machine 420 and the washing water circulation device 400a.
[0205] The washing machine 420 includes an internal electrical system 421 and a plug 422.
[0206] The washing machine's internal electrical system 421 is a circuit that supplies power to components that operate on electricity, such as the drive system devices including the motor that rotates the washing tub 121 and the water supply valve, as well as electrical components such as the control panel.
[0207] The washing water circulation device 400a includes a power supply device 460, an internal electrical system 461 for the washing water circulation device, a plug 462, a power supply device 463, and an ammeter 464.
[0208] The power supply unit 460 is a device that draws power by plugging its plug 462 into an external power source, such as a commercial power outlet.
[0209] The electrical system 461 within the washing water circulation device is a circuit that supplies power to components that operate on electricity, such as the drive system devices 432, the first submersible pump 408, the second submersible pump 418, and electrical components 450.
[0210] The power supply device 463 is a device that receives power via the power supply unit 460 and supplies power to external devices via a plug inserted into the outlet of the power supply device 463. By connecting the plug 422 of the washing machine 420 to the power supply device 463, the washing machine 420 is powered via the power supply unit 460 of the washing water circulation device 400a.
[0211] The ammeter 464 measures the amount of current supplied from the power supply unit 460 to the power supply unit 463 and outputs it to the controller 450.
[0212] The controller 450 transmits control signals, such as drive signals, stop signals, and valve opening / closing signals, to the drive system devices and transmission components that make up the electrical system 461 within the washing water circulation device.
[0213] Figure 19 shows the relationship between the operation of the washing machine 420 and the operation of the washing water circulation device 400a.
[0214] The washing water circulation device 400a needs to switch the flow path of the flow path switching device 432 and operate the first submersible pump 408 and the second submersible pump 418 in response to the operation of the washing machine 420. Therefore, the controller 450 determines the operation of the washing machine 420 based on the measurement value of the ammeter 464 and outputs various control signals to the flow path switching device 432, the first submersible pump 408 and the second submersible pump 418.
[0215] In Figure 19, the standard process for the washing machine 420 involves one wash cycle, one pre-spin cycle, one rinse cycle, and one spin cycle to wash clothes.
[0216] For the sake of explanation, let's assume that the power consumption of the washing machine 420 has three stages: 0 when the main power is OFF, W1 when the main power is ON in standby mode, and W2 when the washing tub is rotating. These power consumption levels are a model case, and in reality, there may be more complex fluctuations in power consumption.
[0217] As power consumption increases, the readings from the ammeter 464 also increase.
[0218] Therefore, when the current meter 464 reading rises from zero (when the measured value M1 is obtained as the current at power consumption W1), the controller 450 controls the flow path of the flow path switching device 432 to the temporary storage tank 401 for washing in preparation for the washing process, and turns on the first submersible pump 408, i.e., outputs an operation signal. It also outputs an "open" signal to the outlet valve 433v (normally closed). The outlet valve 433v may remain "open" until the main power is turned off, and the washing machine 420 controls the drainage from the washing machine 420.
[0219] Subsequently, when the water supply for washing begins and the washing tub 121 rotates, the ammeter 464 obtains a measured value M2 as the current at the power consumption W2.
[0220] When the washing cycle is complete and the washing tub 121 stops, the current measured by the ammeter 464 becomes M1. The controller 450 determines that the washing cycle is complete and sends a stop signal to the first submersible pump 408. The drained washing water is supplied to the temporary washing storage tank 401 via the inlet 431 and the flow path switching device 432.
[0221] The controller 450 determines that the pre-dehydration process has started when the reading from the ammeter 464 rises to M2. The wash water drained during the pre-dehydration process is supplied to the temporary washing storage tank 401.
[0222] When the controller 450 obtains the measured value M1 from the ammeter 464, it determines that the preliminary dewatering process is finished and the rinsing process is starting. Therefore, the flow path switching device 432 opens the flow path to the temporary storage tank 411 for rinsing and outputs an operation signal to the second submersible pump 418.
[0223] When the rinsing process begins and the washing tub 121 rotates, the controller 450 obtains a measurement value M2 from the ammeter 464. When rinsing is complete, the washing tub 121 stops and the controller 450 obtains a measurement value M1 from the ammeter 464. The controller 450 turns off the second submersible pump 418 (outputs a stop signal).
[0224] Subsequently, when the rinse water is drained and the spin-drying process begins, the controller 450 starts the spin-drying process, the washing tub 121 rotates, and the measurement value M2 is acquired. When the spin-drying process is finished, the main power to the washing machine 420 is turned off and the measurement value 0 is acquired. In response, the controller 450 returns the flow path switching device 432 to the neutral position. Furthermore, it outputs a "closed" signal to the outlet valve 433v.
[0225] According to this embodiment, by connecting the water inlet of an existing washing machine with the outlet, drain, and inlet of the washing water circulation device 400a, and plugging the plug 462 of the washing machine 420 into the outlet of the power supply device 463 of the washing water circulation device 400a, washing water and rinse water can be reused.
[0226] The embodiments described above are merely examples of the present invention, and the present invention is not limited to these embodiments. For example, any combination of the above embodiments is included within the scope of the present invention.
[0227] The present invention also includes variations different from the embodiments described above.
[0228] For example, the installation locations of valves and pumps are not limited to those mentioned above and can be changed as appropriate.
[0229] Furthermore, the location of the ultraviolet irradiation lamp or ultraviolet LED that irradiates ultraviolet light toward the rinse water is not limited to inside the tank before the filter, but may be located at any position along the rinse water circulation path. Preferably, it is located in a place where the rinse water accumulates, for example, inside the tank. This allows for a longer ultraviolet irradiation time, and consequently, a longer sterilization treatment time.
[0230] Furthermore, the washing systems of the first to third embodiments described above may be implemented in a single washing machine, or conversely, the washing machines of the fourth to sixth embodiments may be configured such that, for example, the washing tub and the ion water tank are separate components, and a coin laundry system is constructed in which the ion water tank is shared among multiple washing tubs. Also, the washing machine may be a household washing machine or a commercial washing machine. Thus, the washing system according to the present invention can be realized in various forms such as coin laundries, commercial washing machines, and household washing machines, and regardless of the form of implementation, it is included within the scope of the rights of the present invention.
[0231] Furthermore, in the eighth embodiment, the washing machine 420 is powered by the power supply device 463 of the washing water circulation device 400a, and the controller 450 determines the operating status of the washing machine 420 from the fluctuations in the measured values. However, the washing water circulation device 400a may be equipped with a short-range wireless communication device such as Bluetooth®, and configured to notify the controller 450 of the operating status of the washing machine 420 via communication.
[0232] For example, if a user sets a washing sequence for the washing machine 420, such as one wash cycle and two rinses, on a smartphone, the short-range wireless communication device provided in the washing water circulation device 400a receives the sequence information, and the controller 450 of the washing water circulation device 400a controls the flow path of the first submersible pump 408, the second submersible pump 418, the flow path switching device 432, and the opening and closing of the outlet valve 433v based on the received sequence information.
[0233] Furthermore, the eighth embodiment can be described as a configuration in which the washing temporary storage tank 401, the washing filtration standby tank 402, the rinsing temporary storage tank 411, and the rinsing filtration standby tank 412 are all used interchangeably.
[0234] <Ninth Embodiment> A ninth embodiment of the present invention will be described below with reference to Figures 20 to 24.

Figure 23 is a top-down cross-sectional view of the washing system according to the ninth embodiment. Figure 24 is a perspective view of a washing water tank used in a washing system according to the ninth embodiment.
[0236] <Laundry System Configuration> As shown in Figure 20, the laundry system 501 according to the ninth embodiment of the present invention consists of a washing machine 502, a waterproof pan for the washing machine 503, and a laundry water circulation device 504.
[0237] A washing machine 502 is placed on top of a washing machine waterproof tray 503. The washing machine 502 includes a washing tub 521 (see Figure 23), a lid 522, a processor 523, and an operation panel 524.
[0238] The top surface of the washing tub 521 (see Figure 23) can be opened and closed by a manually operated lid 522. The washing tub 521 (see Figure 23) is equipped with an electrically operated locking mechanism (not shown) for locking the lid 522, and the lid 22 is locked in the closed position by a command from the processor 523. The processor 523 controls the operation of the washing tub 521 based on the user's operation on the control panel 524.
[0239] The washing tub 521 is connected to the drain pipe 552 and the water supply pipe 557 shown in Figure 21.
[0240] As shown in Figures 21 to 23, the laundry water circulation device 504 comprises a frame 541, casters 542, adjusters 543, a temporary receiving tank 544, a first pump 545, a fabric softener removal device 546, a filter unit 547, a laundry water tank 548, a second pump 549, an ultraviolet sterilization device 550, control equipment 551, piping 552, 553, 554, 555, 556, 557, 558, 559, a bottle attachment housing 560, a gallon laundry water bottle 561, an alkaline ionized water bottle 562, bottle connection parts 563, 564, and control valves 565, 566.
[0241] The lower surface 571 of the frame 541 is fitted with casters 542 for moving the washing water circulation device 504 and adjusters 543 for fixing the washing water circulation device 504 in place.
[0242] The control equipment 551 is housed in the control equipment storage space 572 located at the bottom of the frame 541.
[0243] The temporary receiving tank 544 and the washing water tank 548 are fixed to the frame 541 by bolts. Additionally, the filter unit 547 is detachably mounted to the frame 541.
[0244] One end of the pipe 552 is connected to the drain of the washing machine 502, and the other end is connected to the wastewater inlet 573 of the temporary receiving tank 544.
[0245] The temporary receiving tank 544 stores the wash water used for washing in the washing tub 521 of the washing machine 502, which is then supplied via the piping 552.
[0246] A first pump 545 is installed inside the temporary receiving tank 544. The first pump 545 is controlled by a control device 551, which pressurizes the laundry water inside the temporary receiving tank 544 and sends the water to the fabric softener removal device 546 via the piping 553.
[0247] If the laundry water supplied from the pipe 553 contains fabric softener, the fabric softener removal device 546 removes the fabric softener from the laundry water and sends it via the pipe 554 to the wastewater inlet at the bottom of the filter unit 547.
[0248] The reason for removing fabric softener from the wash water using the fabric softener removal device 546 is that the fabric softener can clog the filter unit 547.
[0249] Furthermore, if the laundry water supplied from the pipe 553 does not contain fabric softener, the fabric softener removal device 546 will send the laundry water via the pipe 554 to the wastewater inlet at the bottom of the filter unit 547.
[0250] The filter unit 547 is a filtration device that removes solid matter contained in the wash water supplied from the pipe 554, and sends the wash water from which the solid matter has been removed to the wash water tank 548 via the pipe 555 from the wash water outlet at the top.
[0251] The washing water tank 548 stores the washing water supplied from the piping 555. The washing water tank 548 is equipped with a water level sensor that detects the water level of the stored washing water. The detection result from the water level sensor is transmitted to the control device 551.
[0252] As shown in Figure 24, the washing water tank 548 has a height L1 of 700 mm, a width L2 of 260 mm, and a depth L3 of 350 mm.
[0253] As shown in Figures 21 to 23, a second pump 549 is provided inside the washing water tank 548. The second pump 549 is controlled by a control device 551, which pressurizes the washing water inside the washing water tank 548 and sends it to the ultraviolet sterilization device 550 via piping 556.
[0254] The ultraviolet sterilization device 550 sterilizes the wash water supplied from the pipe 556 by irradiating it with ultraviolet light, and then supplies the sterilized wash water to the water supply port of the washing machine 502 via the pipe 557.
[0255] The bottle attachment housing 560 is mounted on top of the washing water tank 548 and houses the pipes 558 and 559, the bottle connection parts 563 and 564, and the control valves 565 and 566.
[0256] The bottle attachment housing 560 stably holds the gallon washing water bottle 561 and the alkaline ionized water bottle 562 in a detachable state.
[0257] The upper end of the pipe 558 is fitted with a bottle connector 563 that connects to a gallon bottle of washing water 561. The lower end of the pipe 558 is fitted to the first water inlet on the top surface of the washing water tank 548. A control valve 565 is provided in the middle of the pipe 5589.
[0258] The control valve 565 is opened and closed by the control device 551, and when open, it supplies wash water from the wash water gallon bottle 561 to the wash water tank 548.
[0259] The upper end of the pipe 559 is fitted with a bottle connector 564 that connects to the alkaline ionized water bottle 562. The lower end of the pipe 559 is fitted to a second water inlet on the top surface of the washing water tank 548. A control valve 566 is provided in the middle of the pipe 559. The control valve 566 is opened and closed by the control device 551, and when open, it supplies alkaline ionized water from the alkaline ionized water bottle 562 to the washing water tank 548. One of the most important aspects is to constantly adjust (supply) the alkalinity of the alkaline ionized water in the washing water tank 548 to a certain range. This is because if the alkalinity becomes too neutral, the cleaning and disinfecting power will decrease. For example, the alkalinity is measured using an alkalinity meter, and when it approaches neutral (below a certain threshold), a valve (control valve 566) is adjusted to increase the alkalinity.
[0260] <How the washing system works> Next, we will explain the operation of the washing system 501. First, the user attaches the gallon washing water bottle 561 and the alkaline ionized water bottle 562 to the bottle attachment housing 560, thereby connecting the mouths of the gallon washing water bottle 561 and the alkaline ionized water bottle 562 to the bottle connection parts 563 and 564, respectively.
[0261] As a result, the laundry water from the gallon bottle 561 and the alkaline ionized water from the alkaline ionized water bottle 562 flow into the laundry water tank 548 via pipes 558 and 559, respectively.
[0262] Subsequently, when the water level of the washing water stored in the washing water tank 548 reaches a predetermined level, the water level sensor detects that the predetermined level has been reached, and the control device 551 closes the control valves 565 and 566 based on the detection result of the water level sensor.
[0263] As a result, the washing water tank 548 stores the washing water mixed with alkaline ionized water at a predetermined water level.
[0264] Subsequently, the washing machine 502 starts operating based on user input to the control panel 524, under the control of the processor 523. The processor 523 then sends a water supply command to the control device 551 of the washing water circulation system 504.
[0265] When the control device 551 of the washing water circulation device 504 receives a washing water supply command from the processor 523 of the washing machine 502, it drives the second pump 549 and also drives the ultraviolet sterilization device 550.
[0266] As a result, the wash water inside the wash water tank 548 is sent to the ultraviolet sterilization device 550 via the pipe 556. The ultraviolet sterilization device 550 sterilizes the wash water by irradiating it with ultraviolet light, and then sends the sterilized wash water to the washing tub 521 of the washing machine 502 via the water supply port of the washing machine 502 through the pipe 557.
[0267] Next, the washing machine 502 uses the wash water supplied to the washing tub 521 from the pipe 557 to wash the laundry (for example, clothes). After washing, the washing machine 502 sends the wash water used in the washing tub 521 to the temporary receiving tank 544 via the pipe 552. The temporary receiving tank 544 temporarily stores the sent wash water.
[0268] Subsequently, the first pump 545 is controlled by the control device 551 and sends the wash water from the temporary receiving tank 544 to the fabric softener removal device 546 via the piping 553. The fabric softener removal device 546 is controlled by the control device 551 and, if the wash water sent from the piping 553 contains fabric softener, removes the fabric softener from the wash water and sends it via the piping 554 to the wastewater inlet at the bottom of the filter unit 547. If the wash water sent from the piping 553 does not contain fabric softener, the fabric softener removal device 546 sends the wash water via the piping 554 to the wastewater inlet at the bottom of the filter unit 547. This softener removal device 546 is not essential. However, if oil components such as softeners enter the filter unit 547, there is a risk of clogging the filter, significantly reducing the performance of the filter. Moreover, in a washing environment where there is a possibility of混入 of clothing containing softeners (it is normal for softener components used in previous washings etc. to remain), the softener removal device 546 is extremely important. Naturally, it is necessary to install the softener removal device 546 before the filter unit 547.
[0269] The filter unit 547 removes solids contained in the washing water supplied from the pipe 554 and sends the washing water from which the solids have been removed to the washing water tank 548 via the pipe 555 from the upper washing water outlet.
[0270] The washing water tank 548 stores the washing water supplied from the pipe 555. After the washing water in the temporary receiving tank 544 is sent to the washing water tank 548 by the first pump 545, if the detection result of the water level sensor has not reached the preset water level, the control device 551 opens the control valves 565 and 566 based on the detection result of the water level sensor until the detection result of the water level sensor reaches the preset water level. After that, when the detection result of the water level sensor reaches the preset water level, the control device 551 closes the control valves 565 and 566. Thereby, the washing water tank 548 stores the washing water at the preset water level.
[0271] After that, when washing the next laundry, the washing machine 502 starts operating based on the user's operation on the operation panel 524. Thereby, the processor 523 sends a washing water supply command to the control device 551 of the washing water circulation device 504.
[0272] As a result, the control device 551 of the washing water circulation device 504 drives and controls the second pump 549 and the ultraviolet sterilization device 550. As a result, the washing water inside the washing water tank 548 is sent to the ultraviolet sterilization device 550 via the piping 556. The ultraviolet sterilization device 550 sterilizes the washing water and sends the sterilized washing water to the washing tub 521 of the washing machine 502 via the water supply port of the washing machine 502 through the piping 557.
[0273] After this, the washing machine 502 uses the wash water supplied to the washing tub 521 from the pipe 557 to wash the laundry. The washing system 501 repeats these washing operations.
[0274] The gallon bottle 561 of laundry water and the alkaline ionized water bottle 562 are provided by the sales company and replaced once a month. The filter unit 547 is provided by the distributor and is replaced every three months.
[0275] <Summary of the configuration and effects of the ninth embodiment> To summarize the configuration and effects of this ninth embodiment, the washing system 501 includes a washing tub 521 for washing laundry using washing water, a washing water tank 548, a washing water supply means (control device 551, piping 558, bottle connection part 563, control valve 565) for supplying washing water to the washing water tank 548, and an alkaline ionized water supply means for supplying alkaline ionized water to the washing water tank 548 and mixing the alkaline ionized water with the washing water stored in the washing water tank 548. The system includes a stage (control device 551, piping 559, bottle connection part 564, control valve 566), a first wash water circulation path (second pump 549, ultraviolet sterilization device 550, piping 556, 557) that supplies wash water stored in the wash water tank 548 to the washing tub 521, and a second wash water circulation path (first pump 545, fabric softener removal device 546, filter unit 547, piping 552, 553, 554, 555) that sends the wash water used by the washing tub 521 for washing back to the wash water tank 548.
[0276] Furthermore, the washing system 501 according to the ninth embodiment includes a washing tub 521 for washing laundry using washing water, a washing water tank 548, a washing water supply means (control device 551, piping 558, bottle connection part 563, control valve 565) for supplying washing water stored in a first bottle (washing water gallon bottle 561) to the washing water tank 548, and by supplying alkaline ionized water stored in a second bottle (alkaline ionized water bottle 562) to the washing water tank 548, the washing water stored in the washing water tank 548 is treated with the alkaline ionized water. The system includes an alkaline ionized water supply means for mixing dissolved water (control device 551, piping 559, bottle connection part 564, control valve 566), a first wash water circulation path (second pump 549, ultraviolet sterilization device 550, piping 556, 557) for supplying wash water stored in the wash water tank 548 to the wash tub 521, and a second wash water circulation path (first pump 545, fabric softener removal device 546, filter unit 547, piping 552, 553, 554, 555) for sending the wash water used by the wash tub 521 to the wash water tank 548.
[0277] Furthermore, the washing system 501 further includes a filtration device (filter unit 547) provided in the second washing water circulation path, which removes solid matter contained in the washing water used by the washing tub 521 for washing.
[0278] Furthermore, the washing system 501 further includes a fabric softener removal device 546 provided between the washing tub 521 and the filtration device (filter unit 547) in the second washing water circulation path, which removes fabric softener contained in the washing water.
[0279] With this configuration, the washing system 501 according to the ninth embodiment can reduce the cost of washing clothes because the washing water discharged from the washing tub 521 after washing is stored in the washing water tank 548 via a second washing water circulation path, and can be reused in the washing process of another load of laundry by being supplied back to the washing tub 521 via the first washing water circulation path.
[0280] Furthermore, in the washing system 501 according to the ninth embodiment, the washing water gallon bottle 561, the alkaline ionized water bottle 562, and the filter unit 547 are provided and replaced by the sales company, thus expanding the sales company's business opportunities.
[0281] Furthermore, the washing system 501 may be equipped with drainage facilities as ancillary equipment. Furthermore, while Figures 20 and 23 illustrate a top-loading washing machine (beat wash type washing machine), a twin-tub washing machine (a washing machine with separate washing and spin-drying tubs) or a front-loading washing machine (big drum) may also be used.
[0282] Furthermore, while the ninth embodiment used a laundry system installed in a typical household, other laundry systems such as those installed in laundry shops, accommodations, or factories can also be used. More specifically, the laundry shop may have two or more washing tubs 521, and fewer than the number of washing tubs 521, including filter units 547, etc. (at least one of a washing water tank 548, a fabric softener removal device 546, etc.). In such cases, by having multiple washing tubs 521, it becomes possible to perform laundry for multiple users, while also being able to use an integrated filter unit 547, which improves equipment efficiency, reduces costs, and simplifies maintenance.
[0283] In either embodiment, it becomes possible to recycle and reuse the water. Therefore, the selective system can be operated even in areas where it is difficult to obtain a supply of clean water (areas with access to clean water are rather few on Earth, and in many developing countries, supplying clean water itself is difficult), in spaces (such as inside ships and submarines), and in areas where water itself is scarce (deserts). Furthermore, the amount of wastewater generated can be drastically reduced, significantly lowering the environmental burden. Rather, all the wastewater can be easily recovered, and thus can be properly treated to render it harmless and discharged into the environment, or reused as the water for this washing system. As described above, it is possible to provide a washing system that is extremely environmentally considerate.
[0284] With the above, the description of the specific embodiments ends. However, the aspects of the present invention are not limited to these. For example, in the first to ninth embodiments, the laundry is clothing, but various items such as shoes, futons, stuffed toys, etc. can be applicable as the laundry. In addition, as long as it is within the scope not departing from the gist of the present invention, the specific configuration of the washing system, the specific procedures for operation determination and operation command output control, etc. can also be appropriately changed.
