Best Way to Carry Out the Invention
    Reference will now be made in detail to preferred embodiments of the present invention, examples of which are illustrated in the accompanying figures. FIG. 1 is a perspective view of an exemplary condensation type washing machine 10 with a drying function; As shown in FIG. 1, washing machine 10 may include a box 11 having a receiving space defined therein, a basket 12 received in box 11, a drum 13 rotatably mounted in basket 12, a condensing duct 14 formed outside basket 12 for condense air containing generated moisture from basket 12, a heating duct 15 connected downstream of condensing duct 14 to heat air using a heater 16 and to supply the heated air into basket 12, and a blow fan 17 to circulate air from basket 12 through condensing duct 14 and heating duct 15.
    In such a washing machine 10, air moved by blowing fan 17 during drying can be heated by heater 16 provided in heating duct 15, and heated air can be supplied to basket 12 to dry the garment during rotation of drum 13. the air used to dry the garment is relatively moist and is introduced into condensing duct 14 from basket 12. In condensing duct 14, moisture is removed from the moist air. Additional cooling water to condense the moist air can be supplied to the condensing duct 14. The air from the condensing duct 14 can be supplied to the heating duct 15 by the blowing fan 17.
    The condenser duct 14 can be shaped like a pipe to enhance the blowing fan 17's air blowing capability and smooth airflow. Moisture contained in moist air can be condensed through heat exchange between the inner surface of the condensing duct 14 and the moist air. As a result, moisture can be removed from the air. Depending on moisture levels, it may be necessary to continuously supply a relatively large amount of cooling water during drying to sufficiently condense moisture from moist air introduced into condenser duct 14. However, the area of condenser duct 14 is relatively small due to space constraints inside box 11, and therefore it may be necessary to supply a relatively large amount of cooling water for a relatively long period of time, thus increasing cooling water consumption and drying time.
    Additionally, during drying, fibers contained in the garment may be introduced into the condenser duct 14 with air may remain in the condenser duct 14, the blow fan 17 and the heating duct 15. Fibers remaining in the condenser duct 14 may reduce efficiency of condensing duct 14. Fibers remaining in blowing fan 17 can impair operation of blowing fan 17. Fibers remaining in heating duct 15 can cause operational problems or combustion of heater 16 provided in heating duct 15.

    Wash water to wash and rinse garments, cleaning water to clean the fiber filter 162 and cooling water to cool the basket 120 to generate condensed water can be supplied to the garment treating machine 100.
    Hereinafter, construction of the water supply device 180, the filter cleaning device 200 and the cooling water supply device 300 and a water supply structure will be described with respect to the accompanying figures.
    As shown in FIG. 6, a valve assembly 170 can selectively or simultaneously supply water from an external water source to respective components (e.g., water supply device 180, filter cleaning device 200, and water supply device of cooling 300). Valve assembly 170 may include a plurality of valves corresponding to respective components to which water is to be supplied. That is, the valve assembly 170 may include a water supply valve 172 to control the supply of wash water (or rinse water) to the water supply device 180, a cleaning water valve 174 to control the supply. of cleaning water to the filter cleaning device 200, and a cooling water valve 176 to control the supply of cooling water to the inner surface of the basket 120 to generate condensed water. Valve assembly 170 may also include one or more additional valves in a case where one or more additional components (eg, a steam generator) using water are additionally provided.
    The water supply device 180 may include a water supply line 182 for receiving wash water from the water supply valve 172 and a soap supply device 184 mounted on the water supply line 182 for receiving soap, so that the water supplied through the water supply line 182 is introduced into the basket 120 along with the soap. Wash water, having passed through the soap supply device 184, can be supplied to the basket 120 from the front of the basket 120 through an additional hose.
    The filter cleaning device 200 can separate fibers from the fiber filter 162 using washing water supplied from the water supply device 180, so that fibers are collected in the basket 120. Hereinafter, the filter cleaning device 200 of the garment processing machine 100 will be described in detail with reference to FIGs. 7A to 10.
    As described above, air can be heated by heating duct 164 and introduced into drum 130 through air discharge port 165 connected to the upper front of basket 120. High temperature dry air can dry garments in drum 130, with the a result that high temperature dry air becomes high humidity air containing moisture. High humidity air containing moisture flows into heating duct 164 through air collection port 161 connected to the upper rear of basket 120 to achieve air circulation.
    The air passing through the air collection port 161, ie the air used to dry garments, may contain foreign matter and fibers and therefore it may be necessary to filter the air. Accordingly, the garment processing machine 100 can include a fiber filter 162 provided at the air collection port 161 to filter foreign matter and fibers contained in the air passing through the air collection port 161. A filtering effect can be improved by an increased sectional area of the fiber filter 162. To that end, the fiber filter 162 may be provided in the air collection port 161 at a predetermined angle of inclination as shown in FIGs. 7A and 7B.
    As previously described, it may be necessary to remove fibers accumulated in the fiber filter 162 after long-term use of the garment treating machine 100. That is, if the fiber filter 162 is clogged by fibers after long-term use of the garment treating machine 100, the amount of air that passes through the air collection port 161 and introduced into the heating duct 164 can be considerably reduced. Under this condition, the blow fan 163 may overrotate due to the reduction in the amount of air introduced (acting as friction force), and the heater may overheat. These abnormalities can cause operational problems and pose a fire hazard.
    Therefore, a filter cleaning device 200 for spraying cleaning water downwardly onto the fiber filter 162 to remove fibers from the fiber filter 162 can be provided above the fiber filter 162 at the air collection port 161.
    The filter cleaning device 200 may include a gripping member 210 connected to a cleaning water line 202 of the water supply device 180 provided in the garment treating machine 100, the gripping member 210 having a hollow portion through which cleaning water can flow, a main body 220 extending from the gripping member 210, and a cleaning water spray device 230 attached to the underside of the main body 220, the cleaning water spray device 230 having one side open through which cleaning water introduced into clamping member 219 can flow, and the other side closed, so that cleaning water is sprayed downwardly.
    The gripping member 210 may be connected to a water supply channel formed in the shape of a tube or pipe. For example, gripping member 210 may be circular in shape. Clamping member 210 can be provided perpendicularly to one side of air collection port 161 to prevent cleaning water leakage and easy clamping between clamping member 210 and air collection port 161. clamping between clamping member 210 and air collection port 161 can be adjusted as needed for a particular installation environment.
    A spray module formed by the main body 220 together with the cleaning water spray device 230 can be arranged parallel to the clamping member 210 perpendicularly to one side of the air collection port 161 as shown in FIG. 7A. Alternatively, the spray module can be tilted so that the tip of the spray module is higher than the clamping member 210 as shown in FIG. 7B. When the spray module is tilted such that the tip of the spray module is higher than the clamping member 210 as indicated in FIG. 7B, the height difference between the spray module and the fiber filter 162 can increase impact with respect to fibers affixed to the underside of the fiber filter 162 and a spray radius of the cleaning water spray device 230 can be increased . Consequently, a fiber removal efficiency of the spray module shown in FIG. 7B may be slightly larger than that of the spray module shown in FIG. 7A.
    Referring to FIG. 9, the gripping member 210 may include a gripping rib 215 extending from the outer circumference thereof to prevent leakage of cleaning water from the air collection port 161 during spraying of the cleaning water. The clamping rib 215 can more securely clamp the filter cleaning device 200 to the air collection port 161.
    In certain embodiments, the filter cleaning device 200 can operate only when fibers are collected to such an extent that the fibers disturb the passage of air through the fiber filter 162.
    That is, the filter cleaning device 200 can be formed into a shape corresponding to the sectional area of the fiber filter 162 to remove fibers. Additionally, the filter cleaning device 200 can be formed into a shape to minimally restrict interference with the air flow passing through the air collection port 161. Consequently, the main body 220 can be shaped like a long rod that does not interfere with the airflow that passes through the air collection port 161.
    The main body 220 may include a water leakage prevention protrusion 225 slanted towards the clamping member 210 to primarily prevent the leakage of cleaning water from the air collection port 161 during spraying the cleaning water in the same manner as the clamping rib 215 of clamping member 210.
    Referring to FIG. 8, the cleaning water spray device 230 may include a plurality of first spray nozzles 231 formed on the edge thereof at a predetermined angle and a plurality of second spray nozzles 233 formed on the middle portion thereof and between the respective first ones. spray nozzles 231 for spraying cleaning water in the vertical direction, i.e. in a direction somewhat orthogonal to the face of the spray device 230.
    The first spray nozzles 231 can be formed protrudingly. Each of the first spray nozzles 231 may include a spray orifice formed on one side of a protruding portion thereof so as to form a certain spray angle with respect to the center of the cleaning water spray device 230. first spray nozzles 231 may have a wider radius cleaning range to clean fiber filter 162.
    The first spray nozzles 231 and the second spray nozzles 233 can be formed to be symmetrical with respect to a longitudinal axis of the cleaning water spray device 230. However, arrangement of the spray nozzles can be adjusted as appropriate .
    The filter cleaning device 200, i.e. the clamping member 210, the main body 220 and the cleaning water spray device 230, can be manufactured by injection molding. For example, gripping member 210 and main body 220 can be formed integrally by injection molding through a single process. The cleaning water spray device 230 can be formed separately by injection molding due to the structural features of the first spray nozzles 231, which are protrudingly formed. In that case, the main body 220 and the cleaning water spray unit 230 can be coupled together by welding between the gripping surfaces of the main body 220 and the cleaning water spray unit 230. However, the method of coupling can be adjusted as appropriate.
    The cooling water supply device 300 can generate condensed water using the rear of the rear basket 120. The cooling water supply device 300 can supply cooling water to the rear of the rear basket 120 so that the rear of the rear basket 120 acts as a condensing surface. Hereinafter, the cooling water supply device 300 will be described in detail with respect to FIGs. 11 and 12. As shown in FIGs. 11 and 12, the cooling water supply device 300 may include a cooling water line 310 for receiving cooling water from the cooling water valve 176 and a cooling water nozzle 320 disposed on the upper rear side. of basket 120 to spray cooling water to the rear inner surface of the basket 120. The cooling water nozzle 320 can be provided on the upper rear part of the basket 120. The cooling water nozzle 320 can be formed in a direction opposite the door of air collection 161 formed in basket 120 around rotating shaft 135. For example, cooling water nozzle 320 may be located at an angle of about 20 to 40 degrees with respect to a vertical axis passing through the shaft. rotary 135. Such an orientation of the cooling water nozzle 320 can allow cooling water sprayed from the cooling water nozzle 320 to flow smoothly along the rear of the bowl. to 120.
    That is, in a case where the cooling water nozzle 320 is located in the middle top of the basket 120, cooling water sprayed from the cooling water nozzle 320 can flow vertically along the back gasket 126 and the wall rear of basket 125 coupled to rear of basket 120. As a result, cooling water flow area is reduced and time provided for cooling rear of basket 120 is relatively short, thus deteriorating a basket cooling effect 120.
    In a case where the cooling water nozzle 320 is located at the edge of the basket 120, cooling water flow area sprayed from the cooling water nozzle 320 is reduced and time provided to cool the rear of the basket 120 is relatively short, thus deteriorating a cooling effect of the basket 120.
    In contrast, in a case where the cooling water nozzle 320 is provided at an angle of about 20 to 40 degrees with respect to the vertical axis in a direction opposite the air collection port 161 as described above, cooling water sprayed from the cooling water nozzle 320 flows down along the rear of the basket 120 for a relatively long period of time and into a relatively large flow area to cool the basket 120, thus improving a cooling effect of the basket 120.
    That is, by generating condensed water using the inner surface of the basket 120 in this way, the condensed water can be generated using a wider area, thus improving a condensed water generating effect.
    Cooling water nozzle 320 can spray cooling water supplied from cooling water line 310 widely to the rear of basket 120. Cooling water nozzle 320 can have a hollow body. A connecting end 322, to which the cooling water line 310 is connected, can be formed on top of the cooling water nozzle 320, and a nozzle end 326, which is located inside the basket 120, can be formed at the bottom of the cooling water nozzle 320. Between the connecting end 322 and the nozzle end 326 there may be a catch end 324, whereby the cooling water nozzle 320 is mounted to the basket 120. A catch plate deflection 328, to deflect cooling water to the rear of the basket 120 in a spread shape, may be provided at the bottom of the nozzle end 326.
    Hereinafter, operation of a machine for treating garments as modalized and broadly described here will be described. The filter cleaning device and the cooling water supply device can be operated during a drying cycle of the garment treating machine 100. Accordingly, a description of a washing cycle and a rinsing cycle of the garment treating machine 100 will be omitted, and the drying cycle 15 of the garment processing machine 100 will be described briefly.
    First, the blow fan 163 of the air supply device 160 can be operated for one cycle. As blow fan 163 is operated, air from basket 120 can be drawn through air collection port 161 and routed to heating duct 164 by blow fan 163. Air 20 routed to heating duct 164 can be heated by the heater provided in heating duct 164 and supplied to basket 120 through air discharge port 165.
    Air supplied to basket 120 can dry garments in basket 120 (specifically, drum 130). The air used to dry clothing can become moist due to moisture evaporated from the clothing. Moist air can be introduced through air collection port 161 and circulated.
    Fibers generated during garment drying can be filtered through the fiber filter 162 of the air collection port 161. The filtered fibers can be separated from the fiber filter 162 by operating the filter 200 cleaning device during the drying cycle or during a wash/rinse cycle, introduced into basket 120 and discharged from the machine to treat garment 100 through the drain device.
    Moisture generated from the garment during the above process can be circulated along with the air. Moisture can be removed by the cooling water supply device 300. Firstly, when cooling water is supplied under the control of the cooling water valve 176, the cooling water can flow along the cooling water line 310 and be sprayed at the rear of the basket 120 through the cooling water nozzle 320. The cooling water sprayed at the rear of the basket 120 can flow down along the rear of the basket 120 to cool the inner circumference of the basket 120. Therein At this time, heat exchange between the humid air and the surface of the basket 120 can be performed so that moisture contained in the humid air is condensed at the rear of the basket 120 and condensed air is generated.
    The cooling water provided by the cooling water supply device 300 can be discharged from the machine to treat garment 100 through the drainage device after cooling the rear of the basket 120. Supply time and intervals of the cooling water provided by the device 300 cooling water supplies may be less than the drain time and intervals of cooling water drained by the drain device. In that case, the residence time of the cooling water in the basket 12 can be increased to further improve a basket cooling effect. Cooling water can be repeatedly supplied several times, or several dozen times, such as, for example, supplying cooling water for 3 to 5 seconds and stopping the cooling water supply for 5 to 7 seconds. In addition, the cooling water can be drained repeatedly several times to several dozen times under a condition where the cooling water is drained for 10 to 20 seconds and the cooling water drain is stopped for 240 to 270 seconds.
    In a washing machine as modalized and broadly described here, moist air having a high temperature may remain in basket 120, with air outside basket 120 having a lower temperature than the air inside the basket, 120, allowing the air to be condensed on the inner circumference of the basket 120 due to the temperature difference between the interior and the exterior of the basket 120, even though no water is supplied from the cooling water supply device 300.
    Even in that case, an amount of condensation may be greater than an amount of condensation provided by the condensation duct 14 shown in FIG. 1. That is, in the condensation duct 14, condensation is derived through an area smaller than the inner circumference of basket 120. In a case where condensation is derived on the inner circumference of basket 120, on the other hand, the surface of cooling for condensing is higher, the condensing surface larger, improving condensing efficiency.
    Furthermore, because cooling water is supplied to the rear of the basket 120, cooling efficiency may be greater than in a case where no cooling water is supplied to the rear of the basket 120.
