  As shown in FIGS. 1 and 2, a garment processing apparatus 100 according to the present invention includes a cabinet 1 forming an appearance, and a garment in which an object to be washed (laundry) and washing water are stored. The housing portions 2 and 3, the circulation duct 7 for circulating the air inside the clothing housing portion, the exhaust duct 83 for discharging a part of the air inside the clothing housing portion to the outside of the clothing housing portion, and the clothing housing portion An air intake duct 81 that supplies outside air to the inside and a heating unit that supplies heated air to the clothing storage unit are included.

  The cabinet 1 includes a front panel 11 that forms a front surface of a clothing processing apparatus, and the front panel 11 has a slot for loading laundry into and out of the laundry from the clothing storage unit. 13 is provided.

  The insertion port 13 is opened and closed by a door 14 (see FIG. 6) that is rotatably coupled to the cabinet 1.

  The front panel 11 can be provided with a control panel 17 that is a user interface. The control panel 17 is a means that allows a user to exchange information with a control unit (not shown) of the clothing processing apparatus 100.

  That is, the control panel 17 includes a power input unit 179 that allows the user to input a power supply command to the clothing processing apparatus 100 and an input unit 175 that allows the user to select a clothing processing method that the clothing processing apparatus 100 can implement. And are provided.

  The “clothing processing method” selected via the input unit 175 is for a control unit (not shown) to control each device provided in the clothing processing apparatus 100 so that moisture and air can be supplied to the laundry. Is a set of time-series control commands or non-time-series control commands.

  “Information about the operation process of the clothing processing apparatus” displayed on the display unit 177 includes the name of the clothing processing method selected by the user via the input unit 175, the time set for the clothing processing method selected by the user, The concept including the scheduled completion time or remaining time of the clothing processing method being executed, the items requested by the user of the clothing processing device 100 to execute the clothing processing method selected by the user (the operation of the clothing processing device and the like) Related information).

  The clothing container provided in the cabinet 1 can include a tab 2 in which washing water is stored, and a drum 3 that is rotatably provided in the tab and stores laundry.

  The tab 2 is provided in a cylindrical shape, is fixed inside the cabinet 1 by a tab support portion 21, and has a tab insertion port 22 communicating with the insertion port 13 on the front surface.

  A gasket 23 is provided between the tab slot 22 and the slot 13, and the gasket 23 not only blocks the vibration generated in the tab 2 from being transmitted to the cabinet 1 but also stores it inside the tab 2. In order to prevent the washed water from leaking, it is preferable to form the elastic material such as rubber.

  The drum 3 is rotatably supported inside the tab 2 by a driving unit M (see FIG. 6) provided on the back surface of the tab 2, and a drum insertion port 31 communicating with the tab insertion port 22, and the circumference of the drum 3 And a through hole 33 penetrating the surface.

  The circulation duct 7 is a flow path for guiding the air inside the tab 2 to the outside of the tab 2 and then guiding it to the tab 2 again, and can be provided on the upper circumferential surface of the tab.

  The tab 2 can be provided with a first communication portion 26 and a second communication portion 27 for coupling with the circulation duct 7.

  As shown in FIG. 2, the first communication portion 26 (duct communication portion) is a flow path for guiding the air inside the tab 2 to the circulation duct 7, and the second communication portion 27 is formed inside the circulation duct 7. It becomes a flow path for guiding the inflowed air to the tab 2.

  The second communication part 27 can be provided in the gasket 23. That is, the second communication portion 27 is provided as a hole penetrating the gasket 23, and the air discharge port of the circulation duct 7 can be coupled to the hole formed in the gasket 23.

  Similarly to the first communication portion 26, the second communication portion 27 may be provided on the circumferential surface of the tab. However, when the second communication portion 27 is provided on the gasket 23, the air discharged from the circulation duct 7 is discharged. Since it can supply to the center part of the drum 3 through the drum insertion port 31, it is advantageous in improving the heat exchange efficiency between the laundry and air.

  The heating unit provided to supply heated air to the tab 2 can include a fan 71 and a heater 73 provided inside the circulation duct 7. The fan 71 is a means that not only causes the air inside the tub 2 to flow into the circulation duct 7 via the first communication portion 26 but also moves the air that has flowed into the circulation duct 7 to the second communication portion 27. 73 is a means for heating the air moving to the second communication part 27 through the fan 71.

  In this case, the first communication portion 26 and the second communication portion 27 are provided so as to be positioned diagonally with respect to the cross section of the tab parallel to the ground on which the cabinet 1 is supported, and the heater 73 is connected to the circulation duct 7. It may be provided so as to include a portion extending along the longitudinal direction. This is to ensure a sufficient time for the air moving along the circulation duct 7 to be heated by increasing the length of the flow path formed by the circulation duct 7.

  In the clothing processing apparatus 100 of the present invention, a part of the air supplied to the heater 73 is supplied via the intake duct 81, and a part of the hot air supplied to the tab 2 is outside the tab 2 via the exhaust duct 83. To discharge.

  The intake duct 81 is preferably provided on a flow path through which air inside the tab 2 flows into the fan 71. This is because the air circulation inside the tab 2 and the air outside the tab 2 are allowed to flow into the circulation duct only by the fan 71 provided in the circulation duct 7 without providing a separate air inflow means in the intake duct 81. is there.

  FIG. 2 shows an example in which the intake duct 81 allows air outside the tab 2 to flow into the circulation duct 7 via the first communication portion 26. In this case, when the fan 71 rotates, negative pressure is formed in the first communication portion 26, so that air inside the tab 2 and air outside the tab 2 flow into the circulation duct 7.

  On the other hand, as shown in FIG. 3, the intake duct 81 provided in the present invention does not require any separate control means (such as a valve) for controlling the opening and closing of the intake duct 81. That is, the intake duct 81 provided in the present invention can always be kept open.

  However, the intake duct 81 can be configured by a fastening portion 811 that communicates with the first communication portion 26 and an extension portion 813 that extends from the fastening portion toward the circulation duct 7. In this case, the extension portion 813 must be provided with an intake port 815 through which outside air flows, and the fastening portion 811 must be provided with an exhaust port 817 that connects the intake duct 81 and the first communication portion 26.

  The extension portion 813 is preferably provided to extend from the fastening portion 811 along the height direction of the tab 2 by a predetermined length. This is to prevent foam induced by the detergent during washing of the laundry from being discharged to the outside of the tab 2 through the intake duct 81.

  The intake duct 81 provided in the present invention has one end fixed to the tab 2 and the other end fixed to the circulation duct 7. This is possible because the circulation duct 7 provided in the present invention is fixed to the upper circumferential surface of the tab 2.

  When the clothing processing apparatus 100 of the present invention is viewed from the viewpoint of the vibration system, the circulation duct 7 and the tab 2 vibrate substantially the same, so that the intake duct 81 connects the tab 2 and the circulation duct 7. Even if it is provided, the durability of the intake duct 81 can be maintained.

  If the circulation duct 7 is not fixed to the upper circumferential surface of the tab 2 but a structure fixed to the cabinet 1, the circulation duct 7 vibrates independently of the vibration of the tab 2. Therefore, if there is no separate vibration absorber, it is difficult to ensure the durability of the intake duct 81.

  In order to fix the free end of the intake duct 81 (one end of the intake duct provided with the intake port 815), the circulation duct 7 may further include a fixing portion 75 to which the intake port 815 is coupled.

  The fixing portion 75 may have any shape as long as the free end of the intake duct 81 can be fixed. FIG. 3 shows an example in which the fixing part 75 has a shape of a board that connects the circulation duct 7 and the air inlet 815.

  Further, the intake duct 81 may further include a first filter F1 that filters air flowing into the extension portion 813. Since the air outside the tab 2 is supplied to the inside of the tab 2 through the intake duct 81, the foreign matter contained in the air prevents the clothes housed inside the tab 2 from being contaminated, This is to prevent malfunction of the heating units 71 and 73.

  In this case, the first filter F1 may be positioned in a hole provided so as to penetrate the fixing portion 75, and the air inlet 815 may be fixed to the fixing portion 75 so as to surround the first filter F1.

  Meanwhile, the first communication part 26 may further include a second filter F2 that filters air flowing from the tab 2 into the circulation duct 7.

  Since the first filter F1 is provided in a state of being exposed to the outside of the circulation duct 7, the first filter F1 is easy to clean, but the second filter F2 is not exposed to the outside of the circulation duct 7. , Difficult to wash. Therefore, the present invention can further include a filter cleaning unit F3 for cleaning the second filter F2.

  The filter cleaning unit F3 may be provided at any position of the first communication unit 26 as long as the cleaning water can be sprayed onto the second filter F2 to remove foreign matters remaining on the second filter F2. b) shows a case where the filter cleaning unit F3 is positioned between the second filter F2 and the fan 71 as an example.

  In this case, it is preferable that the fastening portion 811 extends by a predetermined length along the width direction of the tab 2 and is then coupled to the extension portion 813 in order to avoid interference with the filter cleaning portion F3.

  The exhaust duct 83 may be provided at any position on the tab 2 as long as a part of the air flowing into the tab 2 through the circulation duct 7 can be discharged to the outside of the tab.

  FIG. 1 shows an example where the exhaust duct 83 is provided in the third communication portion 28 provided on the upper circumferential surface of the tab 2. When air is supplied to the inside of the tab 2 by the fan 71, since the inside of the tab 2 is in a positive pressure state, a part of the air inside the tab 2 is at atmospheric pressure via the exhaust duct 83. It is discharged to the outside of the tab 2 that is in a state (lower than the pressure inside the tab), and the remaining air inside the tab 2 is circulated through the first communication portion 26 that is in a negative pressure state. Move to duct 7.

  The cross-sectional area of the exhaust duct 83 is the cross-sectional area of the first communication portion 26 (or the circulation duct) so that only part of the air supplied to the tab 2 via the circulation duct 7 can be discharged via the exhaust duct 83. Smaller than the cross-sectional area).

  On the other hand, in order to keep the flow rate of the air supplied to the inside of the tab 2 constant, the flow rate (exhaust amount) that can be discharged by the exhaust duct 83 and the flow rate (intake amount) that can be sucked by the intake duct 81 are the same. Or it is preferable to set substantially the same.

  The exhaust duct 83 may be provided so that the inside of the tab 2 communicates with the outside of the cabinet 1 to guide the air flowing into the exhaust duct 83 to the outside of the cabinet 1. It is preferable to be connected to a drainage unit 6 provided to discharge water.

  Since the air exhausted through the exhaust duct 83 is highly humid air, when the exhaust duct 83 is provided so as to communicate directly with the outside of the cabinet 1, the air exhausted from the exhaust duct 83 condenses on the indoor wall. This may cause the problem of doing.

  In the garment processing apparatus 100 of the present invention, the drainage part 6 for discharging the washing water inside the tub 2 to the outside of the cabinet 1 is provided. Therefore, if the exhaust duct 83 is connected to the drainage part, the above-described problems are solved. can do.

  In this case, it is preferable that a connection point between the exhaust duct 83 and the drainage unit 6 is further provided with a flow path switching unit 9 that controls opening and closing of the exhaust duct 83 and the drainage unit 6. This is because air discharged through the exhaust duct 83 is prevented from flowing again into the tab 2 and water discharged through the drainage portion 6 is prevented from flowing again into the tab 2.

  The drainage unit 6 provided in the present invention is a first drainage channel 61 and a pump 63 for discharging the wash water inside the tub to the outside of the tub, and a first guide for guiding the wash water discharged from the pump to the channel switching unit 9. 2 The drainage flow path 65 and the 3rd drainage flow path 67 which guides the water which flowed into the flow-path switching part 9 to the outdoor communication part (not shown) like a sewer.

  The flow path switching unit 9 provided at the connection point between the exhaust duct 83 and the drainage unit 6 is preferably provided at a position higher than the highest water level H set in the tab 3 (see FIG. 6).

  In order to prevent malodor from flowing into the interior of the clothing processing apparatus through the flow path connected to the outdoor communication part, such as the third drainage flow path 67, the conventional clothing processing apparatus is provided inside the third drainage flow path. It is common to provide a structure (hereinafter referred to as “water trap”) for preventing water from being completely discharged.

  When the exhaust duct 83 provided in the present invention is connected to the drainage portion provided with the water trap, the air inside the tab 2 is not discharged outside the tab 2 through the exhaust duct 83 when the laundry is dried. Therefore, when the exhaust duct 83 is connected to the drainage unit of the conventional clothing processing apparatus, the control unit must exhaust the air at a pressure that can remove the water trap through the control of the rotational speed of the fan.

  However, when the flow path switching unit 9 is provided at a position higher than the maximum water level set in the tab 2 as in the present invention, the exhaust duct 83 plays a role of preventing siphon phenomenon. The trap is formed between the flow path switching unit 9 and the pump 63 (second drainage flow path 65), and can prevent bad odors from flowing into the tab 2.

  Further, since the air flowing into the exhaust duct 83 can be discharged to the outside of the tub via the flow path switching unit 9 and the third drainage flow path 67, the rotational speed of the fan 71 for removing the water trap is controlled. Is unnecessary.

  Further, through the above-described structure, even when the washing water is supplied up to the maximum water level set in the tab 2, the washing water can be prevented from being discharged to the outside of the tab 2 through the drainage portion 6.

  The flow path switching unit 9 provided in the present invention can be configured as shown in FIG.

  The channel switching unit 9 includes a switching unit body 91 provided at a connection point between the exhaust duct 83 and the second drainage channel 65, a duct connecting pipe 93 that couples the exhaust duct 83 and the switching unit body 91, and a second A flow path connecting pipe 95 that connects the drainage flow path 65 to the switching part body 91 and a discharge pipe 97 that connects the third drainage flow path 67 to the switching part body 91 may be included.

  The duct connection pipe 93 and the flow path connection pipe 95 are provided so as to face each other, the duct connection pipe 93 is provided in the upper part of the switching part body 91, and the flow path connection pipe 95 is provided in the lower part of the switching part body 91. It is preferred that

  In this case, a switching valve 99 for opening and closing the duct connection pipe 93 is provided inside the switching unit body 91. The switching valve 99 includes a valve body 991 that opens and closes the duct connecting pipe 93 and a valve rotation shaft 993 that rotatably fixes the valve body 991 to the switching unit body 91.

  The valve body 991 maintains the state in which the duct connection pipe 93 is opened by dead weight, but when the washing water flows into the switching unit body 91 through the second drainage flow path 65, the duct connection pipe 93 is caused by water pressure. Close.

  On the other hand, when the flow path switching unit 9 is configured only by the above-described structure, the washing water discharged from the tab can be prevented from flowing into the tab 2 through the duct connection pipe 93, but is discharged from the tab 2. There is a problem that the possibility that air is re-supplied to the tab 2 via the flow path connecting pipe 95 cannot be excluded.

  As described above, according to the present invention, since a water trap is generated in the second drainage flow path 65, the air discharged through the exhaust duct 83 can be prevented from flowing again into the tub 2, but the laundry is dried. If the washing water has not been discharged before, the water trap may not be formed in the second drainage flow path 65.

  Therefore, the flow path switching unit 9 provided in the present invention can further include a flow path valve 951 that opens and closes the flow path connecting pipe 95. The flow path valve 951 can be a check valve so that the flow path connection pipe 95 is opened only when the washing water flows into the switching unit body 91 via the second drain flow path 65.

  As shown in FIGS. 1 and 2, the clothing processing apparatus 100 of the present invention further includes a water supply unit 4 that supplies water necessary for washing to the tab 2, and a detergent supply unit 5 that supplies detergent to the tab 2. Can be included.

  The water supply unit 4 opens and closes the water supply channel 43 by a water supply channel 43 that connects the water supply source (not shown) and the tab 2 provided outside the clothing processing apparatus 100 and a control unit (not shown). A water supply valve 41 can be included.

  Meanwhile, the detergent supply unit 5 may include a detergent storage unit 53 in which the detergent is stored, and a tab supply pipe 55 that connects the detergent storage unit 53 and the tab 2. Any form may be used as long as it can supply water. In this case, the control unit (not shown) can supply the tub 2 with the detergent stored in the detergent storage unit 53 and water necessary for washing simply by opening the water supply valve 41.

  On the other hand, the detergent storage part 53 can be provided so that it can be pulled out from the front panel 11. Therefore, the detergent supply unit 5 is further provided with a body 51 that supports the detergent storage unit 53 so that the detergent storage unit 53 can be pulled out from the front panel 11, and the detergent storage unit 53 is pulled out on the front panel 11. The storage part through-hole 15 to be further provided can be provided.

  In this case, the inside of the detergent storage unit 53 must communicate with the body 51, and the tab supply pipe 55 must be provided so as to communicate the body 51 and the inside of the tab 2.

  The control unit (not shown) can control (improve the drying efficiency) the water supply unit 4 so that water necessary for cooling the tab 2 (condensation of air inside the tab) can be supplied to the tab 2. .

  However, the moist air inside the tub 2 is condensed in the detergent supply unit 5 and if the water is supplied to the tub 2 during the drying of the laundry, the laundry stored in the drum 3 may get wet. The clothing processing apparatus 100 of the present invention is preferably configured to further include a water supply guider 25 that allows the tab supply pipe 55 and the tab 2 to communicate with each other.

  The water supply guider 25 provided in the present invention forms a water trap (always stores a certain amount of water and prevents communication between the tub and the detergent supply unit), and the air inside the tub 2 supplies the detergent. By preventing the water from flowing into the portion 5 and allowing water supplied to the tab 2 via the water supply portion 4 to move to the bottom surface of the tab 2 along the inner peripheral surface of the tab 2, It is characterized by preventing the internal laundry from getting wet.

  As shown in FIG. 5, the water supply guider 25 can be provided in a fourth communication portion 29 (water supply communication portion) provided on the upper circumferential surface of the tab 3.

  As shown in the figure, the fourth communication portion 29 may be provided in the shape of a tube protruding from the circumferential surface of the tab, or may be provided as a hole penetrating the circumferential surface of the tab.

  The water supply guider 25 is located in the fourth communication portion 29 and provides a trap body 251 that provides a space for storing water, and a distance between the circumferential surface of the trap body 251 and the inner peripheral surface of the fourth communication portion 29. And a guide pipe 255 that is fixed to the fourth communication portion 29 and guides the water supplied through the tab supply pipe 55 to the inside of the trap body 251.

  The guide tube 255 includes a guide tube body 255 a that guides water to the trap body 251, and a flange 255 b that is provided along the circumferential surface of the guide tube body and fixes the guide tube body 255 a to the fourth communication portion 29. be able to.

  The guide tube body 255a is provided so that the outer peripheral surface has a diameter separated from the inner peripheral surface of the trap body 251 by a predetermined distance, and the lower surface of the guide tube body 255a from which water is discharged is the bottom surface of the trap body 251. It has a length separated by a predetermined distance.

  The flange 255b must be provided so as to close a space between the outer peripheral surface of the guide tube body 255a and the inner peripheral surface of the fourth communication portion 29. As shown in FIG. It may be supported on the upper surface.

  Therefore, the water supplied to the detergent storage unit 53 via the water supply channel 43 is supplied to the trap body 251 via the tab supply pipe 55 and the guide pipe body 255a, and the water supplied to the trap body 251 is trapped. The air flows into the tab 2 through the space between the inner peripheral surface of the body 251 and the outer peripheral surface of the guide tube body 255 a and the space between the outer peripheral surface of the trap body 251 and the inner peripheral surface of the fourth communication portion 29.

  A certain amount of water is always stored in the trap body 251, and the lower surface of the guide tube body 255 a (the surface on which the flange is not provided) is maintained soaked in the water stored in the trap body 251. Therefore, the humid air inside the tab 2 is not supplied to the detergent supply unit 5.

  Further, the above-described water supply guider 25 is provided in the fourth communication portion 29 provided at a position separated by a predetermined distance along the width direction Y of the tab 2 from the vertical line X passing through the rotation center C1 of the drum 3. Even if water is supplied to the inside of the tub 2, the laundry stored in the drum 3 can be prevented from getting wet.

  Further, the fourth communication portion is arranged such that the water supply guider 25 is positioned between the vertical line X1 in contact with the circumferential surface of the drum 3 and the vertical line X2 in contact with the circumferential surface of the tab along the height direction of the tab 2. If 29 is provided, the above-mentioned effect can be maximized.

  On the other hand, when it is difficult to provide the water supply guider 25 at the above-described position, the above-described effects can be achieved by providing the flow path provided in the water supply guider 25 at the above-described position.

  As shown in FIG. 5B, a number of fixing plates 253 for fixing the trap body 251 to the fourth communicating portion 29 are provided along the circumferential surface of the trap body 251, and one fixing plate 253 and another fixing plate 253 are fixed. The space provided between the plate 253 serves as a flow path for allowing the water of the trap body 251 to flow into the tub 2.

  Therefore, a part of the space provided between one fixed plate and the other fixed plate is configured as a closed surface 259, the remaining space is configured as an open surface 257, and the open surface 257 is formed on the drum 3. If it is located between the vertical line X1 in contact with the circumferential surface and the vertical line X2 in contact with the circumferential surface of the tab 2, the laundry is prevented from getting wet by water supplied to the tab 2 during drying. be able to.

  That is, the open surface 257 passes through the center C2 of the fourth communication portion 29 and is a semicircle or a circle located in a direction far from the vertical line X passing through the rotation center C1 of the drum with reference to a straight line Z parallel to the longitudinal direction of the tab. It can be provided in an arc shape.

  When the opening surface 257 is provided in an arc shape, the length of the opening surface 257 can be set to ¼ or more and less than ½ of the length of the circumferential surface of the trap body 251. From the viewpoint of angle, the arc-shaped open surface 257 can have a center angle of 45 degrees or more and less than 180 degrees with respect to the center C2 of the fourth communication portion 29.

  The shape and positional characteristics of the open surface 257 described above are not only to prevent the laundry from getting wet during water supply during drying, but also to minimize an increase in water supply time during washing.

  Referring to FIG. 2, a drying system (a process of drying laundry by supplying heated air to the laundry) implemented by the above-described clothing processing apparatus 100 of the present invention is as follows.

  When the fan 71 operates, the air inside the tub 2 flows into the circulation duct 7 via the first communication portion 26, and the air flowing into the circulation duct 7 is heated by the heater 73, and then the second communication portion 27. To be supplied to the tab 2. The air supplied to the tab 2 exchanges heat with the laundry stored in the drum 3 and then moves toward the first communication portion 26.

  Since the tab 2 exchanges heat with the air inside the cabinet 1 (or air flowing into the cabinet through the cabinet through hole 19 or the like), the temperature of the surface of the tab 2 is kept lower than the center of the tab 2. . Therefore, after being discharged from the drum 3, the air is cooled in the process of moving toward the first communication portion 26, so that a part of the moisture contained in the air is condensed on the inner peripheral surface of the tab 2.

  That is, the tub 2, the circulation duct 7, the fan 71, and the heater 73 provided in the present invention are a circulation type that dehumidifies the air discharged from the tub, heats the dehumidified air, and re-supplys the heated air to the tub. A drying system (first heat exchange channel and heating unit) is formed.

  On the other hand, a part of the air that has been heat exchanged with the laundry is discharged to the outside of the tab 2 through the exhaust duct 83, and the remaining air is recovered to the circulation duct 7 through the first communication portion 26, In this process, the air is mixed with the air outside the tub 2 flowing in through the intake duct 81.

  The air discharged from the drum 3 is dehumidified by exchanging heat with the tab 2 while moving to the first communicating portion 26, but depending on the amount of cloth (the amount of laundry stored in the drum), the circulation duct The air recovered in 7 may be difficult to maintain a state where a sufficient amount of moisture has been removed. The exhaust duct 83 and the intake duct 81 are means for solving such a problem.

  That is, according to the present invention, a part of the air flowing into the first communication portion 26 from the tab 2 is discharged to the outside of the cabinet 1 through the exhaust duct 83, so that the amount of moist air flowing into the circulation duct 7 is increased. The humidity of the air supplied to the heater 73 is desired by mixing dry air (air outside the tub) supplied through the intake duct 81 with air flowing into the circulation duct 7 from the tub 2. Can be lowered to the standard.

  The intake duct 81, the fan 71, the heater 73, and the exhaust duct 83 provided in the present invention not only heat the air outside the tub and supply it to the tub, but also finish the heat exchange with the laundry inside the tub. An exhaust-type drying system (second heat exchange flow path and heating unit) that discharges a part of the air to the outside of the tub is formed.

  Therefore, the present invention is not limited to the amount of laundry and the type of laundry (regardless of the humidity of the air discharged from the tub) through the drying system in which the circulation type drying system and the exhaust type drying system are combined. It can prevent that drying efficiency falls.

  In order to realize the above-described effect, it is preferable that the above-described exhaust duct 83 and intake duct 81 be kept open during drying, and the amount of air flowing into the circulation duct 7 via the intake duct 81 ( It is preferable that the amount of intake air) and the amount of air discharged to the outside of the tab 2 via the exhaust duct 83 (exhaust amount) are substantially the same.

  On the other hand, when the intake air amount and the exhaust air amount are the same, the drying efficiency is the highest. However, when it is difficult to match the intake air amount and the exhaust air amount, it is preferable to set the exhaust air amount larger than the intake air amount.

  If the intake air amount is larger than the exhaust air amount, the amount of hot air supplied to the inside of the tab 2 increases, and the amount of hot air supplied to the inside of the tab increases, which means that the tab 2 must be dehumidified. This means that the amount of air that must be increased. Therefore, if the intake duct and the exhaust duct are provided so that the intake amount becomes larger than the exhaust amount, a problem may occur that drying efficiency is lowered when the laundry is dried without using cooling water. It is preferable to set the exhaust amount larger than the intake amount.

  Although the drying system described above has a risk of increasing the drying time depending on the amount of cloth, the present invention has also solved this problem through the control of the water supply unit 4. That is, in the drying system embodying the present invention, the control unit (not shown) controls the water supply unit 4 so that water is supplied to the inner peripheral surface of the tab 2 during the drying of the laundry. The problems described above can be solved.

  When water for cooling the inner peripheral surface of the tab 2 is supplied to the tab 2 via the water supply unit 4 during drying, the inner peripheral surface of the tab 2 is rapidly cooled, so the humidity of the air flowing into the circulation duct 7 is This is because it is kept low (the dryness of the air flowing into the circulation duct is kept high).

  The water supplied to the tub 2 through the water supply unit 4 is moved to the drainage unit 6 along the inner peripheral surface of the tub by the water supply guider 25, so that the laundry stored in the drum 3 gets wet with water and is dried. The risk of increasing time is also very low.

  On the other hand, in order to save water, it is preferable that the process of supplying water to the tub 2 through the water supply unit 4 is performed by a user's selection. Therefore, the control panel 17 includes a first mode selection unit 171 that supplies water to the tab and dries the laundry, and a second mode selection unit 173 that dries the laundry without supplying water to the tab. It is preferable to further provide (see FIG. 1B).

  On the other hand, the above-described clothing processing apparatus 100 of the present invention may be configured as shown in FIG.

  The clothing processing apparatus 100 shown in FIG. 6 has the same structure as the clothing processing apparatus shown in FIGS. 1 to 5 except for the connection relationship of the circulation duct 7, the intake duct 81, and the exhaust duct 83.

  That is, the tab 2 provided in the present embodiment is supplied with air outside the tab 2 (inside the cabinet or outside the cabinet) via the intake duct 81 and air inside the tab 2 via the exhaust duct 83. Is discharged to the outside, and a part of the air inside the tab 2 is guided to the intake duct 81 through the circulation duct 7 (connection duct).

  The fan 71 and the heater 73 are provided inside the intake duct 81, and the circulation duct 7 is connected to a flow path of the intake duct 81 that guides air to the fan 71 (the circulation duct is an inlet of the fan and the intake duct). Linked between).

  Also in this embodiment, the circulation type drying system is formed by the first heat exchange flow path and the heating units 71 and 73, and the first heat exchange flow path includes the tab 2, the circulation duct 7 (connection duct), and the fan 71. It is comprised by the one part flow path of the intake duct 81 which guides the air discharged | emitted from the tab 2 to the tab 2.

  On the other hand, the exhaust type drying system of the present embodiment is formed by the second heat exchange flow path and the heating units 71 and 73, and the second heat exchange flow path is configured by the intake duct 81, the tab 2 and the exhaust duct 83. .

  Therefore, this embodiment can also realize the same effect as the embodiment described with reference to FIGS.

  FIG. 7 shows a control method of the garment processing apparatus 100 described above. In the control method of the garment processing apparatus of the present invention, a drying step (S30) for supplying heated air to the tab 2 and the progress of the drying step are shown. A motion execution step (S50) for rotating the drum 3 in accordance with a preset motion may be included.

  In the drying step (S30), after the air inside the tab 2 is discharged to the outside of the tab 2, a circulation process (S31) for re-supplying the tab 2 and a part of the air supplied to the inside of the tab are tabbed. An exhaust process (S33) to be discharged outside, an intake process (S35) in which air outside the tab is mixed with air circulating through the circulation process, and a heating process (S37) in which air supplied to the tab 2 is heated. including.

  The circulation process (S31) is a process in which the air inside the tub 2 flows along the circulation duct 7 by the operation of the fan 71, and is started together with the operation of the fan 71. In the circulation process (S 31), not all the air inside the tab 2 flows into the circulation duct 7. That is, part of the air inside the tab 2 is re-supplied to the tab 2 through the circulation process (S31), but part of the air inside the tab is discharged outside the tab through the exhaust process (S33). The

  Since the exhaust process (S33) is performed through the exhaust duct 83, the air discharged from the tab 2 through the exhaust process (S33) passes through the flow path switching unit 9 and the third drainage flow path 67 to the outside of the clothing processing apparatus 100. Move to.

  The intake process (S35) is performed through the intake duct 81, and the intake duct 81 is provided in the first communication portion 26 that connects the circulation duct 7 and the tab 2. Therefore, the circulation process (S31) is performed by the operation of the fan 71. When started, it can be considered that the intake process (S35) is also started.

  The heating process (S37) is a process in which the heater 73 heats the air mixed inside the circulation duct 7 through the circulation process (S31) and the intake process (S35).

  Through the above-described drying step (S30), the present invention supplies heated air, dehumidifies air after heat exchange with the laundry, reheats part of the air discharged from the tab, and is discharged from the tab. It is possible to supply a part of the air, reheated air to the laundry.

  The motion execution step (S50) is executed during the execution of the drying step (S30), and may be provided to execute only one of the first motion and the second motion. (S53) and the second motion execution process (S51) may be executed according to a preset order.

  The first motion execution process (S53) is a process of rotating the drum according to the first motion, and the first motion rotates the drum 3 only in one of the clockwise direction and the counterclockwise direction, This is a motion that increases the heat exchange efficiency between the hot air supplied to the tab 2 and the laundry by repeating that the laundry is in close contact with the inner peripheral surface of the drum 3 and separated (does not fall).

  In the first motion execution process (S53), the drum is rotated at a first rotation speed (reference rotation speed) in which the centrifugal force induced in the laundry by the rotation of the drum 3 is larger than the weight of the laundry (S531). ), The process of rotating the drum 3 at the second rotational speed set to a rotational speed larger than the first rotational speed (S533), and the two processes (S531, S533) are set to the predetermined number of times or are already set. And a process of repeating the time.

  In the process of rotating the drum at the first rotational speed (S531) and the process of rotating the drum at the second rotational speed (S533), the drum 3 rotates only in the same direction, and the first rotational speed and the second rotational speed are: Since the rotation speed is such that the laundry rotates together with the drum 3, the laundry will show the movement shown in FIG. 8 during the first motion execution process (S53).

  That is, when the drum 3 rotates at the first rotation speed, the laundry L maintains a state of being in close contact with the inner peripheral surface of the drum 3 for a certain time (FIG. 8B), and the drum 3 rotates at the second rotation speed. Then, although the laundry L maintains the state closely_contact | adhered to the internal peripheral surface of the drum 3 for a fixed time, compared with the case where a drum rotates at 1st rotation speed, it adheres further to the internal peripheral surface of the drum 3 (FIG. 8). (A)).

  Since the second rotational speed is greater than the first rotational speed, the centrifugal force induced in the laundry is even greater when the drum rotates at the second rotational speed than when the drum rotates at the first rotational speed. Because.

  The first and second rotation speeds are set to rotation speeds at which the laundry L can be rotated together with the drum while being in close contact with the inner peripheral surface of the drum in order to secure a space for moving hot air inside the drum 3. It is. Since the surface area of the laundry that can contact the hot air supplied to the tab by the first motion is maximized, the heat exchange efficiency between the hot air supplied to the tab 2 and the laundry is increased.

  On the other hand, the reason why the first rotation speed and the second rotation speed are set differently is to open and close the through hole 33 provided in the drum 3 by the laundry. That is, hot air is confined in the drum 3 while the drum rotates at the second rotation speed, and air inside the drum 3 is discharged to the tab 2 while the drum rotates at the first rotation speed. .

  In the case of the conventional clothing processing apparatus, a part of the hot air flowing into the drum 3 is discharged to the tab 2 after heat exchange with the laundry, but a part of the air flowing into the drum 3 is discharged to the drum 3. It was immediately discharged to the tab 2 through the provided through-hole 33 without heat exchange with the laundry. Therefore, the conventional clothing processing apparatus has a problem that energy consumption increases because heat exchange efficiency between hot air and laundry is low.

  The present invention can solve the above-mentioned problems of the conventional clothing processing apparatus by controlling the number of revolutions of the drum.

  When the amount of laundry exceeds a certain amount, the laundry is arranged so as to cover the entire inner peripheral surface of the drum, and when the drum 3 rotates at the second rotational speed, the laundry is brought into the drum 3 by a large centrifugal force. Since it is in close contact with the peripheral surface, it is possible to minimize the discharge of hot air inside the drum 3 to the tab 2 through the through hole 33 when the drum rotates at the second rotational speed.

  Further, when the drum rotates at the first rotation speed, the laundry is kept in close contact with the inner peripheral surface of the drum 3 by a relatively small centrifugal force, so that the hot air inside the drum 3 passes through the through hole 33. Can be discharged to the tab 2.

  In order to further increase the efficiency of heat exchange between the laundry and hot air, the time set in the process of rotating the drum at the second rotational speed (S533) is set in the process of rotating the drum at the first rotational speed (S531). It is preferable to set longer than the set time.

  However, since the condensation efficiency of the air moving to the circulation duct 7 can be changed according to the time during which hot air is discharged from the drum 3 to the tab 2 (the amount of hot air discharged to the tab), the drum is moved at the first rotational speed. It is preferable to set the rotation time and the time for rotating the drum at the second rotation number at a constant ratio. FIG. 8 shows an example in which the ratio of the time for rotating the drum at the first number of rotations and the time for rotating the drum at the second number of rotations is 1: 3.

  On the other hand, the second motion execution process (S51) is a process of rotating the drum according to the second motion, and the second motion repeats the rotation of the drum 3 and the stop of the rotation of the drum, This is a motion that drops from the upper part of the horizontal line Y passing through the rotation center C1 of the drum 3 to the lower part of the horizontal line Y (this is a motion that improves the stirring and heat exchange efficiency of the laundry).

  As shown in FIG. 7, in the second motion execution process (S51), the process of rotating the drum 3 at the third rotation speed (S511) and the rotation of the drum before the drum 3 completes one rotation (1 revolution). And a process of repeating the two processes (S511, S513) a preset number of times or a preset time (S515).

  The third rotational speed is set such that the centrifugal force induced in the laundry by the rotation of the drum 3 is greater than the dead weight of the laundry, and the third rotational speed is the first rotational speed or the second rotational speed. It may be set to be the same as any one of the rotational speeds.

  Since the process of stopping the rotation of the drum (S513) is started when the laundry has risen more than half (h) the height of the drum, during the execution of the second motion execution process, the laundry is shown in FIG. The movement of the indicated form will be shown.

  That is, when the drum is rotated at the third number of rotations (S511), the laundry L rotates with the drum 3 while being in close contact with the inner peripheral surface of the drum 3 (FIG. 9A), and the laundry L becomes the drum. When the rotation of the drum is stopped (S513) when the height has risen by half (h) or more of the height, the laundry falls from the upper part of the horizontal line Y toward the inner peripheral surface of the drum 3 located at the lower part of the horizontal line Y ( FIG. 9B).

  The surface area of the laundry exposed to the hot air supplied to the drum 3 is increased by the second motion, and when the laundry L hits the inner peripheral surface of the drum 3, the moisture contained in the laundry is easily separated. Thus, the present invention can increase the heat exchange efficiency between hot air and laundry (increase in drying efficiency).

  Further, the second motion is provided so that the laundry repeats rising and falling inside the drum 3, so that the laundry is prevented from being entangled inside the drum 3.

  The process of stopping the rotation of the drum in order to maximize the above-described effect (S513) is a torque in a direction opposite to the rotation direction of the drum 3 (the rotation direction of the drum when the drum rotation stop process is started) ( (torque) is supplied to the drum 3. This is to provide a greater impact force to the laundry.

  Further, the process of stopping the rotation of the drum (S513) is preferably performed when the laundry is rotated at an angle of 90 degrees or more and less than 180 degrees with reference to the lowest point B of the rotation locus of the drum 3.

  The second motion described above may be set so that the drum 3 rotates only in either the clockwise direction or the counterclockwise direction, as shown in FIG. 9C. As shown, the drum 3 may be set to rotate clockwise and counterclockwise alternately.

  In addition, the process of rotating the drum at the third rotation number (S511) and the process of temporarily stopping the rotation of the drum (S513) are repeated (S515) for the preset time and the preset number of times. The three rotation speeds may be set so as to gradually increase each time the second motion is repeated.

  That is, when the second motion is executed many times, the third rotation speed set for the second motion executed first may be set smaller than the third rotation speed set for the subsequent second motion. (See FIG. 9D).

  Further, the third rotation speed set in the drum rotation process (S511) is set so as to increase each time the second motion is repeated and to decrease after the preset second number of times of the second motion is repeated. May be.

  When the third rotation speed is gradually increased every time the execution of the second motion is repeated, it is easy to remove moisture contained in the laundry.

  On the other hand, the process of executing the second motion (S51) described above is preferably executed before the process of executing the first motion (S53). This is to prevent the laundry from being entangled inside the drum 3 through the second motion so that the laundry 3 can be evenly distributed on the inner peripheral surface of the drum during the execution of the first motion. is there.

  The time set in the process of executing the first motion (S53) is preferably set longer than the time set in the process of executing the second motion (S51). This is to increase the heat exchange rate between the laundry and hot air by increasing the time during which the heat energy supplied to the inside of the drum 3 remains inside the drum 3.

  The control method of the present invention may include only the drying step (S30) and the motion execution step (S50) described above, but may further include a cooling water supply step (S70) shown in FIG. In the cooling water supply step (S70), water is supplied to the inner peripheral surface of the tab 2 during the execution of the motion execution step (S50), and the inner peripheral surface of the tab 2 that exchanges heat with the air discharged from the drum 3 is provided. This is the step of cooling.

  It is preferable that the cooling water supply step (S70) provided in the present invention is executed according to a user's selection. Therefore, the present invention may further include a mode selection step (S10) for setting whether or not to perform the cooling water supply step (S70) before the start of the drying step (S30).

  The mode selection step (S <b> 10) may be a step in which the user inputs a control command via the first mode selection unit 171 and the second mode selection unit 173 provided on the control panel 17.

  The first mode selection unit 171 is a means for selecting a control method (so-called “turbo drying mode”) for executing the cooling water supply step (S70) during the execution of the motion execution step (S50). The second mode selection unit Reference numeral 173 denotes a means for selecting a control method (so-called “wind drying mode”) for performing the motion execution step (S50) without executing the cooling water supply step (S70).

  On the other hand, the mode selection step (S10) includes a cooling water supply step (S70) depending on the amount of laundry stored in the drum 3, regardless of the intention of the user by the control unit (not shown). It may be a step of selecting the first mode.

  In any case, the control method of the present invention determines whether or not the first mode has been selected at the start of the drying step (S30) (S40).

  When the first mode is not selected (when the second mode is selected), the control method of the present invention sequentially executes only the second motion execution process (S51) and the first motion execution process (S53). However, when the first mode is selected, the control method of the present invention performs the cooling water supply step (S70) while the first motion is executed (S53).

  At the beginning of the drying step (S30), the heat exchange rate between the laundry and hot air is low. The dryness of the laundry hardly changes until the laundry reaches a certain temperature, and shows a tendency to increase rapidly after the laundry reaches the certain temperature.

  This is because for the moisture contained in the laundry to evaporate, the temperature of the laundry has to be higher than a certain temperature, and is discharged from the drum 3 as it goes to the latter half of the drying step (S30). It means that the humidity of air becomes high.

  Therefore, when the second motion executed with the start of the drying step (S30) is executed (S51), the start (execution of the second motion) starts after a certain time has elapsed after the start of the drying step (S30). It is more advantageous in drying the laundry that the tub is cooled during the execution of the first motion (started after finishing) (S53).

  Furthermore, the cooling water supply step (S70) is preferably performed during the process (S533) in which the drum rotates at the second rotational speed among the steps included in the first motion.

  This is to prevent the water supplied to the tub 2 through the water supply unit 4 from moving toward the drum 3 to wet the laundry inside the drum 3 (the rotation speed of the drum is high). Then, the water that collides with the outer peripheral surface of the drum moves in a direction away from the drum).

  Thereafter, the control method of the present invention determines whether or not the execution time of the drying step (S30) and the motion execution step (S50) has passed the drying time set in the drying time setting step (S20) (S80). Then, the drying step (S30) and the motion execution step (S50) are completed.

  The drying time setting step (S20) is preferably executed before the start of the drying step (S30). In the drying time setting step (S20), the control unit (not shown) may set the drying time based on the amount of laundry, and the time input by the user via the control panel is set as the drying time. You may make it set.

  The present invention can be modified in various forms, and the scope of right is not limited to the above-described embodiments. Therefore, if a modified embodiment includes the elements of the claims of the present invention, it should be understood that they fall within the scope of the present invention.
