  The clothes storage unit provided in the cabinet 1 may include a tub 2 in which washing water is stored, and a drum 3 rotatably provided inside the tub and in which laundry is stored.

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

  A gasket 23 is provided between the tab inlet 22 and the inlet 13, and the gasket 23 not only blocks the transmission of vibrations generated in the tab 2 to the cabinet 1, but also stores the inside of the tab 2. In order to prevent the washing water from leaking, it is preferable to use an elastic material such as rubber.

  The drum 3 is rotatably supported inside the tab 2 by a drive unit M (see FIG. 6) provided on the back surface of the tab 2 and has a drum inlet 31 communicating with the tab inlet 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 guiding the air 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 connection 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 inside the circulation duct 7. It becomes a flow path for guiding the inflowed air to the tab 2.

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

  Similar to the first communication portion 26, the second communication portion 27 may be provided on the circumferential surface of the tab, but when the second communication portion 27 is provided on the gasket 23, the air discharged from the circulation duct 7 is used. As it can be supplied to the center of the drum 3 through the drum inlet 31, it is advantageous for enhancing the heat exchange efficiency between the laundry and the air.

  The heating unit provided to supply the 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 unit that not only allows the air inside the tub 2 to flow into the circulation duct 7 via the first communication portion 26 but also causes the air flowing into the circulation duct 7 to move to the second communication portion 27. Reference numeral 73 denotes a unit for heating the air moving to the second communication unit 27 through the fan 71.

  In this case, the first communication portion 26 and the second communication portion 27 are provided 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 provided in the circulation duct 7. It may be provided to include a portion extending along the longitudinal direction. By lengthening the length of the flow path formed by the circulation duct 7, it is to ensure a sufficient time for the air moving along the circulation duct 7 to be heated.

  In the clothes treating apparatus 100 according to the present invention, a part of the air supplied to the heater 73 is supplied through the air intake duct 81, and a part of the hot air supplied to the tub 2 is outside the tub 2 through the exhaust duct 83. To drain.

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

  FIG. 2 shows, as an example, the case where the air 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, a negative pressure is formed in the first communication portion 26, so the air inside the tab 2 and the 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 a 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 in communication with the first communication portion 26 and an extension portion 813 extending from the fastening portion toward the circulation duct 7. In this case, the extension portion 813 should be provided with an air inlet 815 into which the outside air flows, and the fastening portion 811 should be provided with an air outlet 817 connecting the air intake duct 81 and the first communication portion 26.

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

  One end of the intake duct 81 provided in the present invention is fixed to the tab 2 and the other end is fixed to the circulation duct 7. This is a possible feature as 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 point of view 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 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 is 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 absorbing device, it is difficult to secure the durability of the intake duct 81.

  In order to fix the free end of the air intake duct 81 (one end of the air intake duct provided with the air intake port 815), the circulation duct 7 may further include a fixing portion 75 to which the air 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, as an example, the case where the fixing portion 75 has the shape of a board connecting the circulation duct 7 and the air inlet 815.

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

  In this case, the first filter F1 may be located in a hole provided 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.

  On the other hand, the first communication portion 26 may further include a second filter F2 for filtering the air flowing from the tub 2 into the circulation duct 7.

  Since the first filter F1 is provided exposed to the outside of the circulation duct 7, the cleaning of the first filter F1 is easy, while 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 washing unit F3 for washing the second filter F2.

  The filter cleaning unit F3 may be provided at any position of the first communication portion 26 as long as foreign matter remaining in the second filter F2 can be removed by spraying cleaning water to the second filter F2, as shown in FIG. b) shows as an example the case where the filter cleaning part F3 is located between the second filter F2 and the fan 71.

  In this case, the fastening portion 811 is preferably connected to the extension portion 813 after being extended by a predetermined length along the width direction of the tab 2 to avoid interference with the filter cleaning portion F3.

  The exhaust duct 83 may be provided at any position of the tab 2 as long as 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, as an example, the case 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, the inside of the tab 2 is in a positive pressure state, so a part of the air inside the tab 2 is at the atmospheric pressure via the exhaust duct 83. The air is exhausted to the outside of the tab 2 which is in the state (state lower than the pressure inside the tab), and the rest of the air inside the tab 2 is circulated through the first communication portion 26 which is in the negative pressure state. Move to the 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 a part of the air supplied to the tub 2 through the circulation duct 7 can be exhausted through the exhaust duct 83 Is preferably smaller than the cross-sectional area of

  On the other hand, in order to maintain the flow rate of air supplied to the inside of the tab 2 constant, the flow rate (exhaust amount) which the exhaust duct 83 can discharge and the flow rate (intake volume) which the air intake duct 81 can inhale are the same. Or it is preferable to set substantially the same.

  The exhaust duct 83 may be provided to communicate the inside of the tab 2 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 the drainage part 6 provided to discharge water.

  Since the air exhausted through the exhaust duct 83 is high humidity air, when the exhaust duct 83 is provided in direct communication with the outside of the cabinet 1, the air exhausted from the exhaust duct 83 condenses on the indoor wall The problem is to be triggered.

  The laundry processing apparatus 100 according to the present invention is provided with the drainage portion 6 for draining the washing water inside the tub 2 to the outside of the cabinet 1, so if the exhaust duct 83 is connected to the drainage portion, the above problem is solved can do.

  In this case, it is preferable that the connection point between the exhaust duct 83 and the drainage portion 6 further include a flow path switching portion 9 for controlling the opening and closing of the exhaust duct 83 and the drainage portion 6. This is to prevent the air discharged through the exhaust duct 83 from re-entering the tab 2 and the water discharged through the drainage portion 6 from re-introducing into the tab 2.

  The drainage portion 6 provided in the present invention guides the first drainage flow path 61 and the pump 63 for discharging the washing water inside the tub to the outside of the tub, and the washing water discharged from the pump to the flow path switching portion 9 2 drainage flow path 65, and the 3rd drainage flow path 67 which guides the water which flowed into flow path switching part 9 to the outdoor communication part (not shown) like a sewer ditch can be included.

  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 maximum water level H (see FIG. 6) set on the tab 3.

  The conventional clothes treating apparatus prevents the odor from flowing into the inside of the clothes treating apparatus through the flow path connected to the outdoor communication part like the third drainage flow path 67. It is general to provide a structure (hereinafter referred to as a "water trap") for preventing the 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 tub 2 is not exhausted to the outside of the tub 2 through the exhaust duct 83 when the laundry is dried. Therefore, when the exhaust duct 83 is connected to the drainage portion of the conventional clothes processing apparatus, the control unit must discharge the air at a pressure that can remove the water trap through control of the rotational speed of the fan.

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

  In addition, since the air flowing into the exhaust duct 83 can be discharged to the outside of the tab through the flow path switching unit 9 and the third drainage flow path 67, the control of the number of rotations of the fan 71 for removing the water trap Is unnecessary.

  In addition, through the above-described structure, even if the washing water is supplied to the maximum water level set in the tub 2, the washing water can be prevented from being discharged to the outside of the tub 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 flow path switching portion 9 includes a switching portion body 91 provided at a connection point between the exhaust duct 83 and the second drainage flow path 65, a duct connecting pipe 93 for connecting the exhaust duct 83 and the switching portion body 91, A flow path connecting pipe 95 connecting the drainage flow path 65 to the switching portion body 91 and a discharge pipe 97 connecting the third drainage flow path 67 to the switching portion body 91 may be included.

  The duct connection pipe 93 and the flow path connection pipe 95 are provided to face each other, the duct connection pipe 93 is provided on the upper portion of the switching portion body 91, and the flow path connection pipe 95 is provided on the lower portion of the switching portion body 91. Being preferred.

  In this case, a switching valve 99 for opening and closing the duct connection pipe 93 is provided inside the switching portion body 91. The switching valve 99 includes a valve body 991 for opening and closing the duct connection pipe 93 and a valve rotation shaft 993 for rotatably fixing the valve body 991 to the switching portion body 91.

  The valve body 991 maintains the state in which the duct connection pipe 93 is opened by dead weight, but when washing water flows into the switching portion body 91 through the second drainage channel 65, the duct connection pipe 93 is hydraulically operated. Close.

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

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

  Therefore, the flow path switching unit 9 provided in the present invention can further include a flow path valve 951 for opening and closing the flow path connection pipe 95. The flow path valve 951 can be a check valve so as to open the flow path connection pipe 95 only when the washing water flows into the switching portion body 91 via the second drainage flow path 65.

  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 connecting the detergent storage unit 53 and the tub 2, and the water supply channel 43 may include the detergent storage unit 53. Can be in any form as long as it can supply water. In this case, the controller (not shown) can supply the tub 2 with the detergent stored in the detergent storage 53 and the water necessary for washing only by opening the water supply valve 41.

  On the other hand, the detergent storage unit 53 can be provided so as to be able to be pulled out from the front panel 11. To that end, the detergent supply unit 5 is further provided with a body 51 supporting the detergent storage unit 53 so that the detergent storage unit 53 can be withdrawn from the front panel 11, and the detergent storage unit 53 is withdrawn from the front panel 11. A reservoir through hole 15 can be further provided.

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

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

  However, if the damp air inside the tub 2 condenses in the detergent supply unit 5 and water is supplied to the tub 2 during the drying of the laundry, the laundry stored in the drum 3 may get wet. The clothes processing apparatus 100 of the present invention is preferably configured to further include a water supply guider 25 that brings the tab supply pipe 55 and the tab 2 into communication.

  The water supply guider 25 is located at the fourth communication portion 29 and a space between the circumferential surface of the trap body 251 and the inner circumferential surface of the fourth communication portion 29 which provides a space in which water is stored. And a guide pipe 255 fixed to the fourth communication portion 29 and guiding 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 255a for guiding water to the trap body 251, and a flange 255b provided along the circumferential surface of the guide tube body and fixing the guide tube body 255a to the fourth communication portion 29. be able to.

  The guide tube body 255 a is provided such that the outer circumferential surface has a diameter spaced apart from the inner circumferential surface of the trap body 251 by a predetermined distance, and the lower surface of the guide tube body 255 a 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 255 b must be provided to close the space between the outer peripheral surface of the guide tube body 255 a and the inner peripheral surface of the fourth communication portion 29, and as shown in FIG. It may be supported on the upper surface.

  Therefore, the water supplied to the detergent storage unit 53 through the water supply flow path 43 is supplied to the trap body 251 through the tab supply pipe 55 and the guide pipe body 255a, and the water supplied to the trap body 251 is a trap. The fluid 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 communicating portion 29.

  A fixed amount of water is constantly stored inside the trap body 251, and the lower surface (the surface without the flange) of the guide tube body 255a is kept immersed in the water stored in the trap body 251. Therefore, the moist air inside the tub 2 is not supplied to the detergent supply unit 5.

  Moreover, since the water supply guider 25 described above is provided at 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.

  Furthermore, the fourth communication portion is 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 effect can be achieved by providing the flow path provided to the water supply guider 25 at the above-described position.

  As shown in FIG. 5B, a large 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 is fixed to the other. A space provided between the plate 253 and the plate 253 serves as a flow path for 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 the closing surface 259, and the remaining space is configured as the open surface 257. If it is positioned 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 supplied to the tab 2 is prevented from being wetted by the water 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 away 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 open surface 257 is provided in an arc shape, the length of the open surface 257 can be 1/4 or more and less than 1/2 of the length of the circumferential surface of the trap body 251. When viewed from the angle, the arc-shaped open surface 257 can have a central angle of 45 degrees or more and less than 180 degrees with reference to the center C2 of the fourth communication unit 29.

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

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

  When the fan 71 operates, the air inside the tab 2 flows into the circulation duct 7 through 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 Is supplied to the tab 2. The air supplied to the tub 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 the air flowing into the cabinet via the cabinet through hole 19 or the like), the temperature of the surface of the tab 2 maintains a lower temperature 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 part of the moisture contained in the air condenses on the inner circumferential surface of the tab 2.

  That is, the tab 2, the circulation duct 7, the fan 71 and the heater 73 provided in the present invention are dehumidified of air discharged from the tab, heating of the dehumidified air, and circulation type for resupplying heated air to the tab. Form a drying system (first heat exchange channel and heating unit).

  On the other hand, part of the air that has completed heat exchange with the laundry is exhausted to the outside of the tub 2 through the exhaust duct 83, and the remaining air is collected into the circulation duct 7 through the first communication portion 26. In this process, the air is mixed with the air outside the inflowing tub 2 through the air intake duct 81.

  The air discharged from the drum 3 is dehumidified by heat exchange with the tab 2 while moving to the first communication 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 with a sufficient amount of water removed. The exhaust duct 83 and the intake duct 81 are means for solving such a problem.

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

  The air 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 finished heat exchange with the laundry inside the tub A vented drying system (second heat exchange channel and heating unit) is formed to discharge part of the air to the outside of the tub.

  Thus, the present invention is directed to a drying system in which a circulating drying system and an exhaust drying system are combined, regardless of the amount of laundry or the type of laundry (regardless of the humidity of air discharged from the tub), It is possible to prevent the drying efficiency from decreasing.

  In order to realize the effects described above, the exhaust duct 83 and the intake duct 81 described above are preferably kept open during drying, and the amount of air flowing into the circulation duct 7 through the intake duct 81 The amount of intake air) and the amount of air (exhaust amount) exhausted to the outside of the tub 2 through the exhaust duct 83 are preferably substantially the same.

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

  If the intake volume is larger than the displacement volume, the amount of hot air supplied to the inside of the tub 2 increases, and the amount of hot air supplied to the inside of the tub increases. It means that the amount of air that must be increased. Therefore, if the intake duct and the exhaust duct are provided such that the intake amount is larger than the exhaust amount, a problem may occur that the drying efficiency is reduced when the laundry is dried without using the cooling water. It is preferable to set the exhaust amount larger than the intake amount.

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

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

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

  Meanwhile, to save water, the process of supplying water to the tub 2 through the water supply unit 4 is preferably performed according to the user's choice. To that end, the control panel 17 includes a first mode selection unit 171 which supplies water to the tub to dry the laundry and a second mode selection unit 173 which dries the laundry without supplying water to the tab. Furthermore, it is preferable to provide (refer FIG.1 (b)).

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

  The clothes processing apparatus 100 shown in FIG. 6 is the same as the structure of the clothes 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 tub 2 (inside the cabinet or outside the cabinet) through the air intake duct 81, and air inside the tub 2 through the exhaust duct 83. Is discharged to the outside, and a part of the air inside the tub 2 is guided to the air intake duct 81 via 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 the flow path of the intake duct 81 for guiding the air to the fan 71 (the circulation duct is an inlet of the fan and the intake duct). Connected between).

  Also in this embodiment, the circulation type drying system is formed by the first heat exchange flow passage and the heating units 71 and 73, and the first heat exchange flow passage includes the tab 2, the circulation duct 7 (connection duct), and the fan 71. And a part of the flow path of the air intake duct 81 for guiding the air discharged from the air duct 2 to the tub 2.

  On the other hand, the exhaust type drying system of the present embodiment is formed by the second heat exchange channel and the heating units 71 and 73, and the second heat exchange channel is constituted 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 in FIGS. 1 to 5.

  FIG. 7 shows a control method of the above-described clothes processing apparatus 100. In the control method of the clothes processing apparatus according to the present invention, the drying step (S30) of supplying heated air to the tub 2 and the progress of the drying steps A motion execution step (S50) may be included to rotate the drum 3 according to a preset motion.

  The drying step (S30) discharges the air inside the tub 2 to the outside of the tub 2, and then re-circulates the tub 2 (S31), and tabs a part of the air supplied inside the tub. The exhaust process (S33) discharged to the outside, the intake process (S35) for mixing the air outside the tub with the air circulating through the circulation process, and the heating process (S37) for heating the air supplied to the tub 2 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 (S31), not all the air inside the tub 2 flows into the circulation duct 7. That is, a part of the air inside the tub 2 is resupplied to the tub 2 through the circulation process (S31), but a part of the air inside the tub is discharged outside the tub through the exhaust process (S33) Ru.

  Since the exhaust process (S33) is performed through the exhaust duct 83, the air discharged from the tub 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 connecting the circulation duct 7 and the tab 2, so the circulation process (S31) is performed by the operation of the fan 71. Once initiated, the inspiratory process (S35) can also be considered as initiated.

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

  Through the above-described drying step (S30), the present invention supplies the heated air, dehumidifies the air which has completed the heat exchange with the laundry, reheats a part of the air discharged from the tub, and discharges it from the tub. It is possible to supply the laundry with a portion of the air, reheated air.

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

  The first motion execution step (S53) is a step 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. It is a motion that improves the heat exchange efficiency of the hot air supplied to the tub 2 and the laundry by repeating the close contact with the inner peripheral surface of the drum 3 and the separation (without falling).

  The first motion execution step (S53) is a step of rotating the drum at a first rotation number (reference rotation number) at which the centrifugal force induced to the laundry by the rotation of the drum 3 is larger than the weight of the laundry (S531). And the step (S533) of rotating the drum 3 at the second rotation number set to a rotation number larger than the first rotation number (S533), and the above-mentioned two steps (S531, S533) And repeating the process.

  In the process of rotating the drum at the first rotation speed (S 531) and in the process of rotating the drum at the second rotation speed (S 533), the drum 3 rotates only in the same direction, and the first rotation speed and the second rotation speed are Since the number of rotations is such that the laundry rotates with the drum 3, during the first motion execution process (S53), the laundry exhibits the motion shown in FIG.

  That is, when the drum 3 is rotated at the first rotation number, the laundry L is kept in close contact with the inner peripheral surface of the drum 3 for a certain period of time (FIG. 8 (b)), and the drum 3 rotates at the second rotation number. Then, the laundry L is kept in close contact with the inner peripheral surface of the drum 3 for a certain period of time, but adheres more closely to the inner peripheral surface of the drum 3 than when the drum rotates at the first rotation speed (FIG. 8) (A).

  Because the second number of rotations is greater than the first number of rotations, the centrifugal force induced by the laundry is greater when the drum is rotated at the second number of rotations than when the drums are rotated at the first number of rotations It is from.

  Setting the first rotation number and the second rotation number so that the laundry L is in close contact with the inner circumferential surface of the drum and can rotate together with the drum ensures a space for the hot air to move inside the drum 3 It is. Since the surface area of the laundry that can be contacted with the hot air supplied to the tub by the first motion is maximized, the heat exchange efficiency between the hot air supplied to the tub 2 and the laundry is enhanced.

  On the other hand, setting the first number of rotations and the second number of rotations differently is to open and close the through holes 33 provided in the drum 3 by the laundry. That is, hot air is confined inside the drum 3 while the drum rotates at the second rotation speed, and the air inside the drum 3 is discharged to the tub 2 while the drum rotates at the first rotation speed. .

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

  The present invention can solve the above-mentioned problems of the conventional clothes treating device by controlling the number of rotations of the drum.

  The laundry is disposed to cover the entire inner peripheral surface of the drum when the amount of laundry exceeds a certain amount, and when the drum 3 is rotated at the second rotation speed, the laundry is subjected to a large centrifugal force and the inside of the drum 3 is Since it adheres to the circumferential surface, when the drum is rotated at the second rotation speed, the hot air inside the drum 3 can be minimized from being discharged to the tab 2 through the through hole 33.

  Further, when the drum is rotated 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 the hot air inside the drum 3 passes through the through holes 33. Can be discharged into the tub 2.

  In order to further increase the heat exchange efficiency between the laundry and the hot air, the time set in the process of rotating the drum at the second rotation speed (S533) is set in the process of rotating the drum at the first rotation speed (S531) It is preferable to set the time 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 (the amount of the hot air discharged to the tub) that the hot air is discharged from the drum 3 to the tub 2, the drum can be It is preferable to set a constant ratio between the time for rotating and the time for rotating the drum at the second rotation number. FIG. 8 shows an example in which the ratio of the time for rotating the drum at the first rotation speed to the time for rotating the drum at the second rotation speed is 1: 3.

  On the other hand, the second motion execution step (S51) is a step of rotating the drum according to the second motion, and the second motion repeats the rotation of the drum 3 and the rotation stop of the drum to repeat the washing, It is a motion to be dropped 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 (a motion to enhance the stirring and heat exchange efficiency of the laundry).

  As shown in FIG. 7, in the second motion execution step (S51), the drum 3 is rotated at the third rotation number (S511), and the drum is rotated before the drum 3 completes one revolution (1 revolution). (S513), and repeating the two steps (S511 and S513) a predetermined number of times or a predetermined time (S515).

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

  Since the process of stopping the rotation of the drum (S513) is started when the laundry has risen by half (h) or more of the height of the drum, the laundry is being executed as shown in FIG. It will show the movement of the form shown.

  That is, when the drum is rotated at the third rotation speed (S511), the laundry L rotates with the drum 3 while keeping in close contact with the inner peripheral surface of the drum 3 (FIG. 9A). When the drum rotation is stopped (S513) when the height is increased by half (h) or more (S513), the laundry falls from the upper portion of the horizontal line Y toward the inner circumferential surface of the drum 3 located at the lower portion of the horizontal line Y As shown in FIG.

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

  Further, since the second motion is provided so that the laundry repeatedly rises and falls in the drum 3, the laundry is also prevented from being entangled in the drum 3.

  In the process of stopping the rotation of the drum (S513) for maximizing the effect described above, torque (in the direction of rotation of the drum at the time when the process of stopping the rotation of the drum is started) This is done by supplying torque to the drum 3. This is to provide the laundry with a greater impact force.

  The step 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 one of the clockwise direction and the counterclockwise direction as shown in FIG. 9 (c), as shown in FIG. 9 (d). As shown, the clockwise rotation of the drum 3 and the counterclockwise rotation may be alternately performed.

  Also, the process of rotating the drum at the third rotation speed (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 revolutions may be set to gradually increase each time the second motion is repeated.

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

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

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

  On the other hand, the step of executing the second motion (S51) is preferably performed prior to the step 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 uniformly distributed to the inner circumferential surface of the drum when the first motion is performed. is there.

  Further, it is preferable that the time set in the step of executing the first motion (S53) is set longer than the time set in the step of executing the second motion (S51). This is to increase the heat exchange rate between the laundry and the hot air by increasing the time for which the thermal energy supplied to the inside of the drum 3 remains in the inside of 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 the 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 execution of the motion execution step (S50), and the inner peripheral surface of the tab 2 which exchanges heat with the air discharged from the drum 3 It is a step of cooling.

  The cooling water supply step (S70) provided in the present invention is preferably performed at the user's choice. To this end, the present invention may further include a mode selection step (S10) for setting whether to perform the cooling water supply step (S70) before the start of the drying step (S30).

  The mode selection step (S10) 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 in the control panel 17.

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

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

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

  If the first mode is not selected (if 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 performed (S53).

  At the beginning of the start of the drying step (S30), the heat exchange rate between the laundry and the hot air is low. The degree of dryness of the laundry hardly changes before the laundry reaches a certain temperature, and tends to increase rapidly from when the laundry reaches a certain temperature.

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

  Therefore, the start (execution of the second motion) occurs when a predetermined time has elapsed after the start of the drying step (S30) rather than when the second motion performed with the start of the drying step (S30) is performed (S51) It is more advantageous in the drying of the laundry to cool the tab during the execution of the first motion (S53), which is started after the end of the work).

  Furthermore, it is preferable that the cooling water supply step (S70) is performed during the process (S533) in which the drum rotates at the second rotation 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 wetting the laundry inside the drum 3 even when moving toward the drum 3 (the rotation speed of the drum is high) Because water that collides with the outer peripheral surface of the drum moves away from the drum).

  Thereafter, in the control method of the present invention, it is determined whether 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) The drying step (S30) and the motion execution step (S50) are completed.

  The drying time setting step (S20) is preferably performed 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 the laundry, and the time input by the user via the control panel is taken as the drying time It may be set.

  The present invention can be modified and implemented in various forms, and the scope of the present invention is not limited to the embodiments described above. Therefore, when the modified embodiment includes the components of the claims of the present invention, it should be understood as being included in the scope of the present invention.
