In this case, a belt of the conveyor may be a general flat belt, or a belt having a net shape or a porous shape in which the washing water or the rinsing water can pass.
- Detailed description thereof will be given below.
- As shown in
FIG. 1 , the integral type washing machine according to a preferable embodiment of the present disclosure includes afeeding part 100, afirst washing part 200, asecond washing part 300, a rinsingpart 400, adewatering part 500, a dischargingpart 600, a water collection tank, and a detergent tank. - First, the feeding
part 100 includes a feeding conveyor installed to convey a laundry to thefirst washing part 200. Further, a roller and/or a sensor for measuring a width and length of an incoming laundry L in a plan view may be further provided in thefeeding part 100 or thefirst washing part 200. As shown inFIG. 2 , the entire washing split region T may be set by a controller based on the width and length of the laundry L measured at the roller and/or the sensor. A contaminated location of the laundry may be designated as a contamination washing split region t in the entire washing split region T. In some embodiments, one or more washing nozzles of thefirst washing part 200 and/or thesecond washing part 300 may be disposed so as to corresponding to each washing split region. Detailed description thereof will be given below - The
first washing part 200 is installed to perform a rough washing and a front face washing with respect to the laundry fed from the feedingpart 100. Thefirst washing part 200 may include a first conveyor installed to convey the laundry L fed from the feedingpart 100 to thesecond washing part 300, a first washing nozzle A-1 installed to inject a washing water toward the laundry L fed from the feedingpart 100, a soakingtank 210 installed so that the laundry passed through the first washing nozzle A-1 is soaked in the washing water, and second washing nozzles B-1, B-2 and B-3 installed to inject the washing water toward the laundry passing through the soakingtank 210 so as to wash the laundry. Thus, in thefirst washing part 200, the laundry L fed from the feedingpart 100 is subjected to the rough washing with the washing water injected from the first washing nozzle A-1. Subsequently, the laundry is completely soaked in the soakingtank 210 and then subjected to the front-face washing with the washing water injected from the second washing nozzles B-1, B-2 and B-3. - The first washing nozzle A-1 may be installed to inject the washing water in the conveyance direction of the laundry, namely in a downwardly inclined direction as shown in
FIG. 1 . - As shown in
FIG. 2 , the second washing nozzles B-1, B-2 and B-3 may be installed in aninstallation bar 220 which is provided in a width direction of the laundry L in a plan view. Oneinstallation bar 220 may be provided as shown inFIG. 2 . Alternatively, a plurality ofinstallation bars 220 may be provided in the travel direction of the laundry (indicated by arrows inFIG. 2 ). In some embodiments, as shown inFIG. 3 , the second washing nozzles B-1, B-2 and B-3 which are provided in one or plural installation bars 220 may be respectively connected tospecific detergent tanks 810 while being connected to ageneral detergent tank 800. - In addition, a portion of the second washing nozzles B-1, B-2 and B-3 connected to the
specific detergent tanks 810 may be controlled so as to inject a general detergent in the normal washing, stop the injection of the general detergent when a contaminated site of the laundry L passes, inject a specific detergent toward the laundry L, and inject the general detergent toward the laundry L when the contaminated sites passed. For example, thespecific detergent tank 810 may be connected to the second washing nozzle B-1 installed in theinstallation bar 220 as shown inFIG. 2 . In a case where the contaminated site is the central site which corresponds to a contamination washing split region 5(t5) in the entire portion of the laundry L in a plan view, when the laundry L enters thesecond washing part 300, the general detergent is injected from the entire washing nozzle B-1 to perform the normal washing. When the contaminated site enters the side of theinstallation bar 220, the injection of the general detergent is stopped and then the specific detergent is injected from a portion of the washing nozzle B-1 which corresponds to the contamination washing split region 5 (t5) as the contaminated site. Thus, the intense washing can be conducted. Thereafter, once the contaminated site passes, the injection of the specific detergent from the portion of the washing nozzle B-1 may be stopped and the injection of the general detergent may be resumed. At this time, a specific detergent that is extremely adapted for the state of the contaminated site may be configured to be selectively injected. As described above, in the case where a site of the laundry L is relatively heavily contaminated, a relatively lightly contaminated site may be subjected to the normal washing with the general detergent during the conveyance of the laundry L, and the relatively heavily contaminated site may be subjected to the intense washing with the specific detergent adapted for the state of the contaminated site. - In an embodiment, an operator may check the contaminated location in the unfolded laundry L, select a contamination washing split region t in the entire washing split region T, which corresponds to the contaminated location, input the selected contamination washing split region t to the controller. Further, the operator may select a specific detergent adapted to treat the contaminated site, and may input information on the specific detergent to the controller. Thus, it is possible to perform the normal washing and the intense washing by specifying the contamination site and injecting the specific detergent only toward the specified contaminated site.
- For example, at least one of the second washing nozzles B-1, B-2 and B-3 may be installed in the conveyance direction of the laundry, and at least one of the second washing nozzles B-1, B-2 and B-3 may be obliquely installed at an angle of about 5 to 45 degrees with respect to the conveyance direction or a direction opposite to the conveyance direction. In this case, the second washing nozzles B-1, B-2 and B-3 may be controlled so as to inject the washing water obliquely in the conveyance direction at the beginning of entry of the laundry L to the nozzles, inject the washing water obliquely in the conveyance direction at the time of entry, and inject the washing water obliquely in the opposite direction at the time of discharge.
- On the other hand, the controller may have a shape of a remote controller that can specify the contamination washing split region t by pressing a button, and may have a shape of a touchscreen that can touch and designate the contamination washing split region t in the entire washing split region T which is displayed on the screen as shown in
FIG. 3 . The touchscreen may be configured such that the entire washing split region T ofFIG. 2 is displayed on the screen and the specific detergents are displayed in type on the screen. Thus, the operator can select one or more contamination washing split regions t on the screen of the touchscreen and select one or more specific detergents on the screen. At this time, in the selection of the specific detergent, a supply amount of the respective specific detergent may be at a minimum by touching an icon of the respective specific detergent one time, may be at a medium by touching the icon two times, and may be at a maximum by touching the icon three times. In addition, the operator may first select the contamination washing split region t in the current laundry L, and then select a type and a supply amount of the specific detergent. Subsequently, the operator may perform the selection operation in the same manner for a next laundry L. Of course, either the selection of the contamination washing split region t or the selection of the specific detergent selection may be performed preferentially. Once both the selections are performed, the same selection may be set to be performed for the next laundry L. In addition, the specific detergent may be selected according to a contaminant of the contaminated site. The type and number of specific detergents may be varied depending on the type of contaminant. - The
second washing part 300 is installed to wash the rear face of the laundry L passed through thefirst washing part 200. Thesecond washing part 300 may include a third washing nozzles C-1, C-2 and C-3 installed to inject the washing water toward the laundry Land a second conveyor installed to convey the laundry L passed through thefirst washing part 200 to the rinsingpart 400. - The third washing nozzles C-1, C-2 and C-3 may be installed and operated identical or similar to the second washing nozzles B-1, B-2 and B-3 described above, and thus the detailed description thereof will be omitted. That is to say, when the contaminated site of the laundry L enters during the normal washing, a portion of the third washing nozzles C-1, C-2 and C-3 may be configured to stop the injection of the general detergent and begin the injection of the specific detergent. Such an operation is identical or similar to that of the second washing nozzles B-1, B-2 and B-3. In addition, at least one nozzle of the third washing nozzles C-1, C-2 and C-3 and rinsing nozzles D-1, D-2, D-3 and D-4 may be installed to inject a fabric softener.

roller 410 and thelower support 420 are installed to press the laundry passed through the rinsing nozzles D-1, D-2, D-3 and D-4 from above and below, and squeeze the rinsing water from the laundry. The rinsingroller 410 and thelower support 420 may be located forward or backward of the rinsing nozzles D-1, D-2, D-3 and D-4 in the conveyance direction of the laundry, and may be installed in each of the rinsing nozzles D-1, D-2, D-3 and D-4. - The
dewatering part 500 is installed to dewater the laundry passed through the rinsingpart 400. Thedewatering part 500 may include at least one of dewatering rollers F1 and F2. - As shown in
FIG. 1 , the dewatering rollers F1 and F2 may be disposed close to rollers installed in the end portion of the third conveyor. Thus, the dewatering rollers F1 and F2, and some rollers of the third conveyor can strongly press and dewater the laundry passing therebetween. - The discharging
part 600 may include a discharge conveyor installed to discharge the laundry passed through thedewatering part 500. - In some embodiments, a drying part including a drying apparatus equipped with a hot air blower and the like for drying the laundry may be further provided between the
dewatering part 500 and the dischargingpart 600. The drying part may be included in the dischargingpart 600 as a unit. - Finally, the water collection tank includes a first
water collection tank 700, a secondwater collection tank 710 and a thirdwater collection tank 720. These water collection tanks may be connected to each other or may be installed to be in communication with at least one of thedewatering part 500, the rinsingpart 400, thesecond washing part 300 and thefirst washing part 200. - The first
water collection tank 700 is installed to collect the water discharged from thedewatering part 500. The collected water of the firstwater collection tank 800 may be supplied into the rinsingpart 500 and may be used as the rinsing water through the rinsing nozzles D-1, D-2, D-3 and D-4. - The second
water collection tank 710 is installed to collect the water discharged from the rinsingpart 400. The collected water of the secondwater collection tank 710 may be reused as the washing water in at least one of thesecond washing part 300 and thefirst washing part 200. To do this, the collected water of the secondwater collection tank 710 may be supplied to at least one of the second washing nozzles B-1, B-2 and B-3, and the first washing nozzle A-1, or the soakingtank 210. - The third
water collection tank 720 is installed to collect the water discharged from thesecond washing part 300. The collected water of the thirdwater collection tank 720 may be reused in thefirst washing part 200. To do this, the collected water of the thirdwater collection tank 720 may be supplied to the first washing nozzle A-1 and the soakingtank 210. - In one example, the water discharged from the
dewatering part 500 is collected in the firstwater collection tank 700, and subsequently, is supplied to the rinsingnozzle 410 of the rinsingpart 400. The water discharged from the rinsingpart 400 is collected in the secondwater collection tank 710, and subsequently, is supplied to the third washing nozzles C-1, C-2 and C-3 of thesecond washing part 300. The water discharged from thesecond washing part 300 is collected in the thirdwater collection tank 720, and subsequently, is supplied to the first washing nozzle A-1 of thefirst washing part 200 and the soakingtank 210. Thereafter, the water may be treated as wastewater. - Therefore, according to the present disclosure, it is possible to reduce water consumption to approximately 50% or less by reusing the water discharged in each process, compared with the case of treating, as the wastewater, the water discharged in the washing, rinsing and dewatering processes as in the related art. More specifically, in the related art, in a case in which 120 bed sheets are washed by a washing machine having a capability of 100kg, all the water of 500L used in a washing step, the water of 500L used in a rinsing step (repeated two or three times), and the water of 500L used in a dewatering step are treated as the wastewater. As a result, a total of 1.5 to 2 tons of water was consumed. However, in the case of using the apparatus of the present disclosure, the water is recycled during the washing, rinsing and dewatering steps, and the wastewater treatment is performed once. This makes it possible to save the water consumption to approximately 50% or less.
