Abstract
Description
[Technical Field]
[0001] The present invention relates to a clothing treatment device and a control method thereof, and more particularly to a clothing treatment device and a control method thereof that can perform a refreshing process such as sterilizing, removing wrinkles, deodorizing, and drying clothing by supplying steam and hot air to the clothing. [Background technology]
[0002] Generally, among the clothing treatment devices, dryers with a rotating drum and clothing management machines with an inner case in which clothing is suspended can perform a drying process to remove moisture from clothing.
[0003] Wrinkles and creases in clothes can only be removed when all three factors - moisture content, temperature, and physical force - are met. However, the dryers and clothes conditioners are designed in such a way that it is difficult to secure a section in the drying process that satisfies all three factors.
[0004] As a result, although the dryer and the clothing care machine can dry the clothes by supplying hot air, wrinkles and creases present in the clothes may not be easily removed.
[0005] FIG. 1 shows the principle by which wrinkles are removed from clothes.
[0006] Referring to FIG. 1(a), the fibers constituting garment L may be knitted in the order 1, 2, 3, 4, and 5. That is, fiber 1, fiber 2, fiber 3, fiber 4, and fiber 5 may be connected by a physical bond (I).
[0007] However, due to their internal chemical structures, when these fibers rub against or come into contact with each other, chemical bonds (II) such as covalent bonds, hydrogen bonds, and intermolecular bonds may occur between the fibers. For example, fiber 1 and fiber 3 may not be connected by a physical bond (I) but may be connected by a chemical bond (II), and fiber 3 and fiber 5 may not be connected by a physical bond (I) but may be connected by a chemical bond (II).
[0008] Therefore, such chemical bonds (II) are generated in a concentrated manner in at least a part of the clothing L, and changes in the arrangement and configuration occur between the fibers where the chemical bonds (II) are generated, ultimately resulting in wrinkles and creases.
[0009] The wrinkles and creases cannot be removed by physical force alone because they are formed by the chemical bond (II).The wrinkles and creases can only be removed after the chemical bond (II) is dissolved.
[0010] Referring to Figure 1(b), in order to remove the wrinkles and creases, moisture is first required to dissolve the chemical bond (II). When water is introduced between the chemical bonds (II) between the fibers, the chemical bonds (II) can be weakened or dissolved.
[0011] The amount of moisture required to remove wrinkles and creases is determined by the moisture content of the clothing, and it is generally known that a moisture content of 5 to 45% is required. Therefore, a moisture content of 5 to 45% can be defined as the "moisture removal content."
[0012] If the clothing contains more moisture than the moisture removal rate, the water will actually bond the fibers together further, and the wrinkle and crease removal effect will be lost. If the clothing contains less moisture than the moisture removal rate, the chemical bonds (II) between the fibers cannot be broken, and the wrinkle and crease removal effect will not be achieved.
[0013] Referring to Figure 1(c), heat or energy is required to break the chemical bonds (II) in order to remove the wrinkles and creases. The chemical bonds (II) between the fibers may weaken when heat is applied. The heat or energy required to remove the wrinkles and creases can be achieved if the temperature at which the fibers are brought into contact is equal to or higher than a set temperature. The set temperature corresponds to a temperature higher than room temperature, for example, 36°C.
[0014] When the temperature of the mixture reaches a high temperature environment equal to or higher than the set temperature while water is still present between the fibers, the chemical bond (II) may be significantly weakened.
[0015] Referring to Figure 1(d), in order to remove the wrinkles and creases, a physical force capable of changing the arrangement of the fibers is required. The physical force may include a tensile force capable of arranging the fibers in the order in which they are connected by the physical bonds (I). The physical force capable of generating the tensile force may be defined as a "removal physical force."
[0016] Referring to Figure 1(e), when chemical bonds (II) are formed in the fibers constituting the garment L and wrinkles and creases are formed in the garment, if the conditions of moisture content to be removed, set temperature, and physical force to be removed are all satisfied, the chemical bonds (II) are dissolved and the fibers are able to align in the order in which they were connected by physical bonds (I), thereby removing the wrinkles and creases.
[0017] Therefore, the removal moisture content, the set temperature, and the removal physical force can be considered to correspond to the conditions for removing wrinkles and creases.
[0018] FIG. 2 shows the situation in which clothes are dried in a dryer.
[0019] The dryer can perform a drying process in which clothes are placed in a drum D and hot air is supplied to remove moisture from the clothes.
[0020] Referring to Figure 2(a), at the beginning of the drying process, the moisture content of the clothes L is generally higher than the moisture removal content, and it is possible that insufficient heat H is being applied inside the drum D.
[0021] Even if drum D is rotating, the clothes with high moisture content are packed together and therefore cannot be subjected to adequate tension.
[0022] As a result, the removal conditions cannot be achieved in the early stages of the drying process, and wrinkles in the clothes cannot be removed.
[0023] Referring to Fig. 2(b), in the middle of the drying process, the moisture content of the clothes L reaches the moisture removal content. However, since a large amount of moisture contained in the clothes L is evaporated, most of the heat H supplied to the inside of the drum D is consumed as heat of vaporization.
[0024] Therefore, the temperature inside the drum D does not reach the set temperature or higher, and therefore all of the removal conditions cannot be met even in the middle of the drying process, and wrinkles in the clothes are not removed.
[0025] Referring to FIG. 2(c), at the end of the drying process, most of the moisture contained in the clothes L evaporates, and the amount of heat absorbed as heat of vaporization decreases rapidly.
[0026] As a result, the temperature inside drum D rises sharply above the set temperature, and the removal temperature is met.
[0027] In addition, since the clothes are dry, they separate and fall inside the rotating drum D. Therefore, the condition of the physical force of removal is also met.
[0028] However, since the clothes L have already been mostly dried, the moisture content of the clothes is lower than the moisture content to be removed.
[0029] Therefore, the removal conditions are not met even at the end of the drying process, and wrinkles in the clothes cannot be removed.
[0030] As a result, it is difficult to form a section that satisfies all of the removal conditions throughout the entire drying process in the dryer.
[0031] Therefore, there is a fundamental problem in that wrinkles in the clothes cannot be removed during the drying process using the conventional clothes treating device.
[0032] As a result, users had to iron the clothes separately to remove wrinkles, and had to take other actions such as adding ice or other substances to the drum at the end of the drying process to meet the moisture content removal requirements.
[0033] In recent years, clothing treatment devices have appeared that can inject steam at the end of the drying process in order to meet the removal conditions at the end of the drying process.
[0034] However, although conventional clothing processing devices can remove wrinkles, they have the problem of having to supply additional moisture to the dried clothes at the end of the drying process and then dry them again, which not only slows down the drying process but also inevitably wastes energy.
[0035] Furthermore, conventional laundry treatment devices have a control limitation in that they must stop the compressor to prevent power consumption exceeding the allowable power amount during the process of driving the heater to supply steam. Therefore, after the drying process is completed, steam must be supplied and the compressor must be driven again to dry, or the compressor must be stopped during the drying process, and then steam must be supplied and driven again, which not only delays the drying process but also significantly reduces drying efficiency.
[0036] Conventional clothing processing devices have a problem in that they are unable to automatically remove wrinkles and creases from clothing during the drying process to remove moisture from the clothing. Summary of the Invention [Problem to be solved by the invention]
[0037] SUMMARY OF THE INVENTION An object of the present invention is to provide a clothes treating device that can remove wrinkles and creases from clothes during the drying process.
[0038] An object of the present invention is to provide a clothes treating device that can maintain the operation of the compressor without interruption even when steam is supplied to remove wrinkles and creases from clothes.
[0039] The present invention aims to provide a clothes treatment device that can ensure a section that satisfies removal conditions during the drying process to remove moisture from clothes.
[0040] An object of the present invention is to provide a clothing processing device that can remove wrinkles and creases from clothing while maintaining energy efficiency in the drying process and preventing delays in drying. [Means for solving the problem]
[0041] In order to solve the above-mentioned problems, the present invention provides a clothing processing device that includes (comprises; constitutes; constructs; sets; encapsulates; contains; has) a cabinet, an inner case that is provided inside the cabinet and that stores clothing, a machine chamber that is provided with a heat supply unit that supplies hot air into the inner case and a steam supply unit that supplies steam, a control unit that is provided in the machine chamber and that controls the heat supply unit and the steam supply unit to perform a drying process that dries the clothing, and a temperature sensor that is provided in the inner case or the machine chamber and that detects the temperature of the air inside the inner case.
[0042] The heat supply unit may include a circulation duct for circulating the air discharged from the inner case, a heat exchanger installed in the circulation duct for dehumidifying and reheating the air, and a compressor for compressing and supplying a refrigerant to the heat exchanger for heat exchange with the air.
[0043] The steam supply unit may include a steam case that stores water for generating the steam, a first heater that is housed in the steam case and heats the water to generate the steam, and a second heater that is spaced apart from the first heater and heats the water to generate the steam.
[0044] When the drying process is performed, the control unit may maintain the operation of the compressor until the drying process is completed or the drying of the laundry is completed.
[0045] The control unit may drive both the first heater and the second heater so as to increase the temperature inside the inner case to a set temperature or higher while the compressor is operating.
[0046] The control unit may stop driving the first heater or the second heater before a constant rate section in which a rate of temperature increase inside the inner case decreases to a reference value or less is completed.
[0047] The control unit may maintain the driving of the first heater or the second heater for a set time in a section where the temperature inside the inner case is equal to or higher than the set temperature.
[0048] The control unit can intermittently and repeatedly drive the first heater or the second heater so as to prevent the temperature inside the inner case from rising to a limit temperature that is higher than the set temperature.
[0049] The control unit may stop driving the first heater or the second heater in a section where a temperature change width inside the inner case is equal to or less than a specific range during the process of driving the compressor.
[0050] The control unit may shut off the steam heater before the rate of temperature increase inside the inner case again exceeds the reference value.
[0051] The control unit can shut off the driving of the steam heater after the temperature inside the inner case reaches a drying temperature higher than the target temperature.
[0052] The second heater may be set to generate less steam than the first heater.
[0053] The amount of steam generated by the second heater may be set to 50 to 150% of the amount of moisture removed by the heat exchanger.
[0054] The inner case 200 may further include a moving hanger that hangs the clothes and is driven to swing the clothes.
[0055] The control unit may drive the moving hanger while the temperature inside the inner case is equal to or higher than the set temperature or while the first heater or the second heater is driven.
[0056] The control unit may drive or stop the moving hanger at a first frequency when the temperature inside the inner case is equal to or lower than a set temperature, and may drive the moving hanger at a second frequency faster than the first frequency when the temperature inside the inner case is equal to or higher than a set temperature.
[0057] When the control unit drives the moving hanger at the second frequency for a reference time, the control unit may drive the moving hanger at a third frequency lower than the second frequency.
[0058] The control unit can drive the moving hanger at a third frequency slower than the second frequency when the temperature rise rate inside the inner case becomes higher than a reference value or when the temperature inside the inner case reaches a drying temperature higher than the set temperature.
[0059] The first frequency may be set to be lower than the third frequency.
[0060] When the drying process is performed, the control unit may maintain the operation of the compressor until the drying process is completed or the drying of the clothes is completed, and may drive the moving hanger so as to at least partially overlap with the section in which the steam heater is driven.
[0061] When the control unit drives the moving hanger before driving the steam heater, the control unit may drive the moving hanger faster in a section where the steam heater is driven.
[0062] When the driving of the moving hanger is interrupted before the steam heater is driven, the control unit may drive the moving hanger in a section where the steam heater is driven.
[0063] If the control unit drives the moving hanger while the steam heater is driven, the control unit may not drive the moving hanger or may drive the moving hanger slowly after the driving of the steam heater is finished.
[0064] When the control unit drives the moving hanger while the steam heater is driven, the control unit may maintain the driving speed of the moving hanger for a certain period of time when the driving of the steam heater is terminated.
[0065] The control unit may drive the steam heater while the compressor is driven.
[0066] The control unit may set different driving frequencies of the moving hanger depending on the temperature inside the inner case.
[0067] The control unit can drive the moving hanger at a first frequency until the temperature inside the inner case reaches a set temperature, and after the temperature inside the inner case reaches the set temperature, drive it at a second frequency faster than the first frequency.
[0068] The control unit can drive the moving hanger at a third frequency lower than the second frequency in a section after the temperature inside the inner case reaches a drying temperature higher than the set temperature.
[0069] The control unit may drive the moving hanger at the second frequency for a set time, and then drive the moving hanger at a third frequency lower than the second frequency.
[0070] The second frequency may be set to the fastest frequency at which the moving hanger operates during the execution of the course.
[0071] The control unit can drive the steam supply unit to increase the temperature inside the inner case to the set temperature or higher.
[0072] The control unit may drive the moving hanger at the second frequency so as to at least partially overlap with a section in which the steam supply unit is driven.
[0073] The control unit can drive the moving hanger at the second frequency after the steam supply unit is driven.
[0074] When the drying process is performed, the control unit may maintain operation of the compressor until the drying process is completed or the clothes are completely dried, and may control the steam heater so that steam is supplied into the inner case while the compressor is operating.
[0075] The control unit may drive the steam heater first, and then drive the compressor.
[0076] The control unit may drive the first heater and the second heater first, and then drive the compressor and the first heater or the second heater simultaneously.
[0077] Even if the operation of the first heater or the second heater is terminated, the operation of the compressor may be maintained. [Effects of the Invention]

[0083] FIG. 3 shows the appearance of the clothing processing device 1 of the present invention.
[0084] Referring to FIG. 3( a ), the clothing treatment device of the present invention may include a cabinet 100 that forms an exterior, and a door 400 that is rotatably coupled to the cabinet 100 .
[0085] The door 400 may include a main body 410 forming the front surface of the cabinet 100, and an installation body 420 extending from one side of the main body 410 and having a display for displaying information about the clothing treatment device installed thereon.
[0086] The installation body 420 may be provided to form a step 430 from the main body 410 toward the rear of the cabinet 100 .
[0087] Meanwhile, at least a portion of the installation body 420 may be disposed behind the main body 410 in a front-rear direction, overlapping the main body 410. Thus, the step 430 may serve as a handle.
[0088] The installation body 420 may be made of a different material or color from the main body 410. The installation body 420 may also be made of a translucent material that allows light emitted from the display to pass through.
[0089] 3(b), an inner case 200 having a storage space 220 for storing clothes may be provided inside the cabinet 100. The inner case 200 has an opening 210 at the front for allowing clothes to enter and exit, and the opening 210 may be closed by the door 400.
[0090] The inner case 200 may be made of a plastic resin, and may be made of a reinforced plastic resin that is not deformed by air at a higher temperature than room temperature, heated air (hereinafter referred to as hot air), steam, or moisture.
[0091] The inner case 200 may have a height greater than a width, so that the clothes can be accommodated in the accommodation space 220 without being folded or wrinkled.
[0092] The clothing disposal device 1 of the present invention may include a hanger part 1000 capable of hanging clothing in the storage space 220 of the inner case 200.
[0093] The hanger unit 1000 is installed on the upper inner surface of the inner case 200 and can be configured to hang the clothes in a hanging or spread state from top to bottom.
[0094] This allows the clothes to be hung inside the inner case 200 without being wrinkled.
[0095] The hanger unit 1000 may be provided to hang a plurality of clothes, and the hanger unit 1000 may hang a plurality of clothes at intervals in the width direction of the inner case 200.
[0096] Therefore, even if multiple pieces of clothing are stored in the inner case 200, they can be hung without touching or interfering with each other. As a result, not only are multiple pieces of clothing not damaged, but the entire clothing can be evenly exposed to hot air and steam.
[0097] That is, the hanger part 1000 may be provided as a simple hanging part provided on the upper part of the inner case 200, and may be provided to fix the clothes in a floating state inside the receiving space 220.
[0098] Alternatively, the hanger part 1000 may be provided as a moving hanger 1000 that is installed on the upper surface of the inner case 200 and swings the clothes.
[0099] The moving hanger 1000 may be provided to move back and forth or rotate back and forth on the upper part of the inner case 200. As a result, the clothes hung on the moving hanger 1000 may be swung in the receiving space 220 to remove foreign matter and be effectively exposed to the supplied steam or hot air.
[0100] The detailed structure and function of the moving hanger 1000 will be described later.
[0101] The inner surface of the door 400 may be provided with a pressure unit 520 for applying pressure to the clothes.
[0102] The pressure unit 520 may include a support unit 522 fixed to the inner surface of the door 400 and supporting one side of the garment, and a compression unit 521 that applies pressure to the garment supported by the support unit 522.
[0103] The pressing portion 521 may be provided to move toward or away from the support portion 522. For example, the pressing portion 521 may be provided on the support portion 522 or the inner surface of the door 400 so as to be rotatable.
[0104] As a result, the compression part 521 and the support part 522 can pressurize both sides of the clothing to remove wrinkles in the clothing and create the desired creases.
[0105] The clothing treatment device of the present invention may include a machine room 300 in which various devices are installed that can supply one or more of hot air or steam to the storage space 220, or absorb the air outside the cabinet 100, purify or dehumidify it, and then discharge it.
[0106] A control unit capable of controlling the laundry treatment device may be installed in the machine room 300. Of course, the control unit may be installed inside the door 400.
[0107] The control unit is configured to control one or more of the electrical components of the clothing treatment device of the present invention and can be configured as a PCB to execute any course of treatment of the clothing.
[0108] The machine chamber 300 is separated or partitioned from the inner case 200, but may be provided to communicate with the inner case 200.
[0109] The machine chamber 300 may be disposed below the inner case 200. As a result, when hot air and steam having a low specific gravity are supplied to the inner case 200, the hot air and steam can be naturally supplied to the clothes.
[0110] The machine room 300 may include a heat supply unit 340 that can supply hot air into the inner case 200. The heat supply unit 340 may be implemented as a heat pump system or as a heater that directly heats air with electrical energy.
[0111] When the heat supply unit 340 is provided as a heat pump system, it may be configured to dehumidify and heat the air discharged from the inner case 200 again and supply the dehumidified and heated air to the inner case 200. The detailed structure will be described later.
[0112] The machine chamber 300 may include a steam supplier 800 that can supply steam into the inner case 200. The steam supplier 800 may be configured to directly supply steam into the inner case 200. A detailed structure thereof will be described later.
[0113] As a result, the inner case 200 may have a plurality of through holes 230 penetrating one surface and communicating with the machine chamber 300 .
[0114] Through the through-holes 230, air in the receiving space 220 can be supplied to the machine room 300, and at least one of hot air and steam generated in the machine room 300 can be supplied to the receiving space 200.
[0115] The through hole 230 may include an inlet hole 231 that penetrates the lower surface of the inner case 200 to allow air inside the inner case 200 to flow into the machine chamber 300, and an exhaust hole 232 that is spaced apart from the inlet hole 231 and penetrates the lower surface of the inner case 200 to discharge hot air generated in the machine chamber 300 into the inner case 200.
[0116] The exhaust hole 232 may be disposed at a position closer to the rear than the front or door 400 on the lower surface of the inner case 200 .
[0117] Also, the exhaust hole 232 may be disposed at an angle to the ground between the lower surface or the rear surface of the inner case 200. The exhaust hole 232 is provided toward the moving hanger 1000, and can guide the hot air to be supplied toward the clothes.
[0118] The inlet hole 231 may be disposed in a position forward of the rear surface of the lower surface of the inner case 200 or closer to the door 400 .
[0119] The inlet hole 231 is disposed farthest from the outlet hole 232, so that the air discharged from the outlet hole 232 can be prevented from being immediately absorbed into the inlet hole 231 without reaching the clothes.
[0120] The through-hole 230 may further include a steam hole 233 that penetrates the lower part of the inner case 200 and guides the steam generated in the steam supplier 800 into the inner case 200 .
[0121] The steam hole 233 may be disposed closer to the discharge hole 232 than the inlet hole 231. For example, the steam hole 233 may be disposed on one side of the discharge hole 232.
[0122] Meanwhile, the machine room 300 may further include a water supply tank 30 for supplying water to the steam supply unit 800 and a drainage tank 40 for collecting condensed water condensed in the heat supply unit 340 .
[0123] The water supply tank 30 and the drainage tank 40 can be detachably provided in front of the machine chamber 300. This allows the clothing treatment device 1 of the present invention to be freely installed without being limited by the water supply source or drainage source.
[0124] Meanwhile, the machine room 300 may further include a drawer 50 that can be pulled out forward and has a separate storage space. For example, the drawer 50 may store a steam generator or an iron.
[0125] FIG. 4 shows the structure of the machine chamber of the clothes treating device of the present invention.
[0126] FIG. 4(a) shows the machine room 300 as seen from the front, and FIG. 4(b) shows the machine room 300 as seen from the rear.
[0127] Inside the machine chamber 300, there may be arranged components for supplying hot air to the clothing treatment space, circulating air within the clothing treatment space, supplying steam to the clothing treatment space, and purifying the air outside the cabinet.
[0128] The machine room 300 may include a base 310 that provides a space for supporting or installing various devices. The base 310 may provide an area for installing various devices.
[0129] The base part 310 may be provided with a circulation duct 320 through which air introduced from the inner case 200 or the outside of the cabinet 100 moves.
[0130] The circulation duct 320 is provided in the form of a case with an open top, and some components of the heat supply unit 340 may be installed inside.
[0131] When the heat supply unit 340 is provided as a heat pump system, the circulation duct 320 may include heat exchangers 341 and 343, which will be described later, and a compressor 342, which supplies high-temperature and high-pressure refrigerant to the heat exchangers.
[0132] The heat exchangers 341 and 343 are housed in the circulation duct 320 and can cool and dehumidify the air flowing through the circulation duct 320 or heat the air to generate hot air.
[0133] When the circulation duct 320 is configured to draw air from the outside of the cabinet 100, an outside air duct 370 for drawing outside air may be installed in front of the circulation duct 320.
[0134] The circulation duct 320 is provided to communicate with the outside air duct 370 and can be provided to selectively draw in outside air.
[0135] The water supply tank and the drainage tank may be detachably coupled to the front surface of the circulation duct 320. The water supply tank 30 and the drainage tank 40 may be disposed on top of the outside air duct 370.
[0136] The circulation duct 320 may be coupled to the base 310 or may be integral with the base 310. For example, the base 310 and the circulation duct 320 are manufactured by injection molding.
[0137] The machine room 300 may include a base cover 360 that connects the circulation duct 320 and the inlet hole 231 .
[0138] The base cover 360 may be coupled to an upper portion of the circulation duct 320 and configured to guide the air drawn in through the inlet 231 into the circulation duct 320 .
[0139] The base cover 360 may cover an upper surface of the circulation duct 320 to prevent the air inside the circulation duct 320 from being discharged to the outside. The lower part of the base cover 360 and the upper surface of the circulation duct 320 may form one surface of a flow path of the circulation duct 320.
[0140] The base cover 360 may include an inlet 362 connecting the inlet hole 231 and the circulation duct 320. The inlet 362 has a duct shape and may serve as an intake duct for sending air from inside the inner case 200 to the circulation duct 320.
[0141] A steam supplier 800 may be installed in the machine chamber 300. The steam supplier 800 is connected to the water tank 30, receives water, generates steam, and supplies the steam to the inner case 200. The steam supplier 800 may be seated on the upper part of the base cover 360.
[0142] The steam supply unit 800 may be disposed outside the circulation duct 320. This prevents the steam supply unit 800 from interfering with the movement of air flowing through the circulation duct 320 or heating the air.
[0143] In addition, the steam supply unit 800 may be disposed at a distance from the inlet 362. For example, the steam supply unit 800 may be disposed rearward of the inlet 362.
[0144] The machine room 300 may include a fan installation unit 350 that connects the circulation duct 320 and the inner case 200. The fan installation unit 350 may include a blower fan 353 that provides power to move air in one direction within the circulation duct 320, and a fan housing 351 that houses the blower fan 353 and is connected to or extended from the circulation duct 320.
[0145] The fan installation unit 350 may include an exhaust duct 352 that connects the circulation duct 320 and the exhaust hole 232 .
[0146] The exhaust duct 352 may be provided extending from the fan housing 351 toward the exhaust hole 232 with a cross section corresponding to the area of the exhaust hole 232 .
[0147] As a result, the air inside the inner case 200 flows in through the base cover 360 , passes through the circulation duct 320 , and is then supplied back into the inner case 200 through the fan installation part 350 .
[0148] Meanwhile, the base part 310 may include a compressor installation part 313 in which the compressor 342 is installed to supply refrigerant to the heat exchangers 341 and 343. The compressor installation part 313 may be disposed outside the circulation duct 320.
[0149] In addition, the base unit 310 may be provided with the control unit 700 for controlling the clothing treatment device of the present invention.
[0150] The base part 310 may include a control part installation part 312 that forms a space below the circulation duct 320 into which the control part 700 is inserted.
[0151] The control unit 700 may be provided to control all electronically controlled electrical components such as the compressor 342, the steam supply unit 800, and the blower fan 353.
[0152] Since the control unit 700 is inserted into and supported by the base unit 310, vibrations generated from the moving hanger 1000 or the clothes can be blocked from being transmitted to the control unit 700 or can be attenuated before being transmitted to the control unit 700.
[0153] In addition, the control unit 700 is installed on the base unit 310 and is close to all the electrical components installed in the machine room 300, so that noise generation and control errors can be prevented.
[0154] In the clothing treatment device of the present invention, the steam supply unit 800 is disposed above the circulation duct 320, and the control unit 700 is disposed below the circulation duct 320. Therefore, the circulation duct 320 may be provided as a straight duct shape between the steam supply unit 800 and the control unit 700. As a result, the flow resistance of air passing through the circulation duct 320 can be minimized.
[0155] The circulation duct 320, the outside air duct 370, the steam supply unit 800, the control unit 700, and the heat supply unit 340 are all installed on the base unit 310, so that the base unit 310 can be configured as an integrated module. This allows the base unit 310 to be pulled out forward or backward in the machine room 300, facilitating the installation and maintenance of most electrical components.
[0156] FIG. 5 shows the machine chamber base structure of the clothes treating device of the present invention.
[0157] FIG. 5(a) is a perspective view of the base portion 310 as seen from the front, and FIGS. 5(b) and 5(c) are perspective views of the base portion 310 as seen from the rear.
[0158] The base 310 may be installed on a base plate that forms the lower surface of the laundry treatment device, or the base 310 itself may form the lower surface of the laundry treatment device.
[0159] The base 310 may include a base bottom 311 that forms a support surface. The base bottom 311 may form the lower surface of the laundry treatment device. The base bottom 311 may also be installed on the upper part of the bottom surface of the cabinet 100 that forms the lower surface of the laundry treatment device.
[0160] The base 310 may be integrally provided with the circulation duct 320, which forms at least a part of a flow path through which air moves. The circulation duct 320 may be formed by extending upward from the bottom of the base 311.
[0161] The circulation duct 320 may include a duct body 321 extending from the base bottom 311 to form a flow path, a heat exchanger installation part 3212 providing a space for installing an evaporator 341 or a condenser 343 inside the duct body 321, and an air discharge part 323 provided at the rear of the duct body 321 to discharge air from inside the duct body 321.
[0162] The air discharge part 323 may have a pipe shape extending rearward from the duct body 321. The diameter of the air discharge part 323 may be smaller than the width of the duct body 321.
[0163] The air discharge part 323 may be connected to the fan housing 350. The air discharged from the air discharge part 323 may be guided into the inner case 200 via the fan housing 350.
[0164] The circulation duct 320 may include an air intake portion 322 formed by penetrating the front surface of a duct body 321 .
[0165] The outside air intake part 322 may be in communication with the outside air duct 370. The outside air duct 370 may be seated and supported in front of the outside air intake part 322.
[0166] The circulation duct 320 may be provided with a damper that opens and closes the outside air intake part 322. By opening and closing the damper, the outside air can be allowed to flow into the circulation duct 320 or blocked.
[0167] The base part 310 may include a compressor installation part 312 that provides a space for installing the compressor 342. The compressor installation part 312 may be formed on one side of the base bottom part 311 or may be formed integrally with the base bottom part 311.
[0168] The compressor mounting part 312 may have a protrusion for supporting the compressor 342. The compressor mounting part 312 may be disposed offset toward the rear of the base part 310. The compressor mounting part 312 may be disposed to overlap at least a portion of the air discharge part 323 in the width direction.
[0169] The compressor installation part 312 may be provided with a buffer member for reducing vibration transmitted from the compressor 342. The buffer member may be fixed to the protrusion.
[0170] The base 310 may include a control unit installation part 313 on which the control unit 700 is installed. The control unit installation part 313 may be formed between the base bottom 311 and the circulation duct 320. The control unit installation part 313 may be formed between the base bottom 311 and the bottom surface of the circulation duct 320. The control unit installation part 313 may be configured in the shape of a duct that is open at either the front or rear at the bottom of the circulation duct 320.
[0171] FIG. 6 shows the circulation duct structure of the clothing treatment device of the present invention.
[0172] The circulation duct 320 may extend from the bottom to the top of the base to form a flow path for air to flow through. The circulation duct 320 may include a heat exchanger installation part 3212 that provides a space for installing an evaporator 341 and a condenser 343. The heat exchanger installation part 3212 may be provided inside the duct body 321.
[0173] The duct body 321 may have an open upper surface, through which a condenser 343 and an evaporator 341 may be inserted and installed.
[0174] The opening of the duct body 321 is covered by the base cover 360 , and the base cover 360 and the duct body 321 may form a flow path of the circulation flow path 320 .
[0175] The front surface of the duct body 321 may be spaced rearward from the front end of the base bottom 311 .
[0176] As a result, the base bottom 311 can secure a support surface 3111 on which one or more of the water supply tank 30, the drainage tank 40 and the outside air duct 370 are installed and supported.
[0177] Meanwhile, the heat supply unit 340 may include an evaporator 341 installed in the circulation duct 320 and configured as a heat exchanger for cooling and dehumidifying the air flowing into the circulation duct 320, a condenser 343 configured as a heat exchanger for heating the air passing through the evaporator 341 to form hot air, a compressor 342 disposed outside the circulation duct 320 and supplying a refrigerant to the condenser 343 for heat exchange with the air, and an expansion valve 344 for expanding and cooling the refrigerant passing through the condenser 343.
[0178] Meanwhile, by molding the duct body 321 integrally with the base portion 310, the height of the heat exchanger installation portion 3212 is ensured, and the heights of the condenser 343 and the evaporator 341 are also increased. As a result, it is possible to reduce the width of the condenser 343 and the evaporator 341 in the front-to-rear direction, and the number of refrigerant pipes passing through the condenser and the evaporator can be reduced. This has the effect of reducing the flow loss of air passing through the condenser and the evaporator.
[0179] Meanwhile, the sum of the lengths of the evaporator 341 and the condenser 343 may be set to be shorter than the length of the heat exchanger installation part 3212. Thus, the length of the heat exchanger installation part 3212 in the front-rear direction may be set to be equal to or shorter than half the length of the duct body 321.
[0180] Therefore, the heat exchanger installation part 3212 can be sufficiently spaced from the outside air intake part 322, so that a sufficient space can be secured inside the circulation duct 320 for the outside air and the air inside the inner case 200 to flow in.
[0181] Meanwhile, an installation partition 3211 may be included inside the duct body 321 to separate the heat exchanger installation portion 3212 from the outside. The installation partition 3211 may protrude from a side of the duct body 321 to support the front of the evaporator 341.
[0182] In addition, the duct body 321 may be expanded in width based on the installation partition wall 3211 and extended rearward.
[0183] As a result, the width of the heat exchanger installation portion 3212 can be set to be larger than half the width of the base portion 310. In addition, the width of the circulation duct 320 can also be set to be larger than half the width of the base portion 310.
[0184] The width of the condenser 343 and the width of the evaporator 341 may also be set to be larger than half the width of the entire base part 310. As described above, by ensuring the widths of the condenser 343 and the evaporator 341, it is possible to ensure a sufficient heat exchange capacity.
[0185] In addition, the fan housing 350 may be disposed so as to overlap the condenser 343 or the evaporator 341 in the front-rear direction. Therefore, the air that has passed through the evaporator 341 and the condenser 343 can flow into the fan housing 350 without bending its flow path. That is, the air that has flowed into the circulation duct 320 does not bend its flow path while moving to the fan housing, which has the effect of minimizing flow loss. The clothing treatment device of the present invention may further include a temperature sensor S1 that detects the temperature inside the inner case 200 or the temperature of the air flowing from the inner case 200 into the circulation duct 320, and a refrigerant sensor S2 that detects the temperature of the refrigerant circulating in the heat supply unit.
[0186] The temperature sensor S1 may be installed on the inner wall of the circulation duct 320, and the refrigerant sensor S2 may be installed on the discharge side of the compressor 342.
[0187] FIG. 7 shows the structure of the air discharge section 323 of the clothing treatment device of the present invention.
[0188] The base portion 310 may include an air outlet 323 that discharges treated air toward a fan housing.
[0189] The air discharge part 323 may be provided to communicate the inside of the circulation duct 320 or the duct body 321 with the fan housing 350. The air discharge part 232 may have a bell mouth shape. The bell mouth shape can reduce air flow loss and improve air circulation efficiency.
[0190] The air exhaust pipe 3232 of the air exhaust part 323 is provided in a pipe shape, and in the process of removing the mold, the mold disposed in front of the parting line 3233 is pulled forward, and the mold disposed behind the parting line 3233 is pulled backward based on the parting line 3233.
[0191] The fan installation part 350 may be coupled to and supported by the air exhaust pipe 3232. The fan housing 351 may have a coupling hole coupled to an outer circumferential surface of the air exhaust pipe 3232, and the blower fan 353 may be disposed in the coupling hole.
[0192] The fan housing 351 may include an exhaust duct 352 extending from the outer circumferential surface or outside of the blower fan 353 to the exhaust hole 232 .
[0193] The fan housing 351 and the exhaust duct 352 accommodate the blower fan 353 therein and form a flow path through which air can move.
[0194] A motor for rotating the blower fan 353 may be coupled to and supported on the outside of the fan housing 351 .
[0195] FIG. 8 shows the structure of the base cover of the clothes treating device of the present invention.
[0196] The base cover 360 may be coupled to an upper surface of the circulation duct 320 to prevent the inside of the circulation duct 320 from being exposed.
[0197] The base cover 360 is coupled to the upper surface of the circulation duct 320 and may include an inlet body 361 that connects the inner case 200 and the circulation duct 320, and a shielding body 363 that extends from the inlet body 361 and shields the circulation duct 320.
[0198] The inflow body 361 may be provided in a duct shape to communicate the inflow hole 231 of the inner case 200 with the inside of the circulation duct 320. The inflow body 361 may be provided to protrude above the shielding body 363.
[0199] The inflow body 361 may be disposed forward of the evaporator 341 and the partition wall 3211 so as not to face the evaporator 341 and the condenser 343 .
[0200] The inflow body 361 may serve as an inflow duct for transferring air from the inner case 200 to the circulation duct 320 .
[0201] The inlet body 361 may have an inlet portion 362 therein through which air in the inner case 200 can pass.
[0202] Specifically, the base cover 360 may include a first rib 362a extending along the width direction of the inlet body 361 and a second rib 362b spaced rearward from the first rib 362a and extending along the width direction of the inlet body 361.
[0203] The first rib 362a and the second rib 362b may be provided side by side. The first rib 362a and the second rib 362b may have a plate shape extending vertically, and the height thereof may be provided to correspond to the height of the inflow body 361.
[0204] The front corner of the inlet body 361 and the first rib 362a may form a first inlet 3621, the first rib 362a and the second rib 362b may form the second inlet 3622, and the second rib 362b and the rear corner of the inlet body 361 may form a third inlet 3623.
[0205] The first inlet 3621 and the third inlet 3623 may have the same area, and the second inlet 3622 may have an area smaller than the areas of the first inlet 3621 and the third inlet 3623 .
[0206] The base cover 360 may include a damper part 364 configured to open and close the inlet part 362, and a driver 365 coupled to the damper part 364 and controlling the opening and closing of the damper part 364.
[0207] The damper part 364 may include a first damper part 3641 configured to open and close the first inlet 3621 and a second damper part 3642 configured to open and close the third inlet 3623 .
[0208] The first damper part 3641 is provided in a plate shape having an area corresponding to the first inlet 3621 and may be rotatably coupled to both sides of the inlet body 361 within the first inlet 3621 .
[0209] The second damper part 3642 is provided in a plate shape having an area corresponding to the third inlet 3623 and may be rotatably coupled to both sides of the inlet body 361 within the third inlet 3623 .
[0210] The second inlet 3622 may be provided with a blocking filter 366 that allows air to pass through but filters out foreign matter such as fine dust and lint.
[0211] The blocking filter 366 may be inserted into the second inlet 3622 to separate the first inlet 3621 from the third inlet 3623. The blocking filter 366 may be disposed to extend from the second inlet 3622 to contact the bottom surface of the circulation duct 320.
[0212] The blocking filter 366 may be a filter capable of filtering out even water, such as a HEPA filter.
[0213] Meanwhile, when the blocking filter 366 is inserted into the second inlet 3622, a blocking member for blocking the second inlet 3622 may be further coupled thereto.
[0214] The driving unit 365 may include a motor that provides power to selectively rotate the first damper unit 3641 and the second damper unit 3642, and a plurality of gear members that mesh with the motor and rotate to selectively rotate the first damper unit 3641 and the second damper unit 3642.
[0215] The first inlet 3621 and the third inlet 3623 can be selectively opened by the driving part 365 .
[0216] By means of the driving part 365, the air stored inside the inner case 200 may flow into the circulation duct 320 along the first inlet 3621, and may also flow into the circulation duct 320 along the third inlet 3623.
[0217] Of course, the drive unit 365 can control the first damper unit 3641 and the second damper unit 3642 to open both the first inlet 3621 and the third inlet 3623, and can also control the first damper unit 3641 and the second damper unit 3642 to block both the first inlet 3621 and the third inlet 3623.
[0218] The driving unit 365 may have any structure as long as it can rotate the first damper unit 3641 and the second damper unit 3642. For example, it may be provided as a combination of a motor, a driving gear rotated by the motor, and a driven gear connected to the first damper unit and the second damper unit and rotated by the rotation of the driving gear.
[0219] The base cover 360 may include a shielding body 363 extending from the inlet body 361 to shield the evaporator 341 and the condenser 343. The shielding body 363 may be provided in a plate shape.
[0220] The base cover 360 may be detachably coupled to the upper surface of the circulation duct 320 via an inlet hook 3612 extending from the lower surface of the inlet body 361 .
[0221] The circulation duct 320 may include a coupling portion that is detachably coupled to the inlet hook 3612 .
[0222] FIG. 9 shows the installation structure of the steam supply unit.
[0223] The steam supply unit 800 may be seated and supported on the base cover 360 .
[0224] The steam supply unit 800 may include a steam generator 810 that is seated on the base cover 360 and stores water for generating the steam.
[0225] The steam supply unit 800 may further include a mounting bracket 870 for fixing the steam generator 810 to the base cover 360 .
[0226] The mounting bracket 870 is coupled to the base cover 360 and can fix the steam generator 810 thereto.
[0227] The installation bracket 870 may include a lower panel 871 that supports the lower surface of the steam generator 810 , and side panels 872 that support both sides of the steam generator 810 on the lower panel 871 .
[0228] The mounting bracket 870 may further include one or more fixing clips 873 extending from the side panel 872 to prevent the steam generator 810 from falling off.
[0229] The fixing clip 873 may be detachably provided on the top or side of the steam generator 810 .
[0230] The compressor 342 may be disposed below the steam supply unit 800 .
[0231] The installation bracket 870 may be provided to block heat generated from the compressor or heat generated from the refrigerant compressed by the compressor from being transferred to the steam supplier 800 .
[0232] The installation bracket 870 can also prevent the fire from spreading to the steam supply unit 800 if a fire occurs in the compressor 342 .
[0233] Meanwhile, the base cover 360 may include a fastening portion 3631 provided on the shielding body 363 and detachably coupled to the steam supplying portion 800. The fastening portion 3631 may be provided as a structure to be detachably coupled to a protrusion protruding from the lower portion of the steam generator 810.
[0234] Therefore, even if a large amount of water is contained inside the steam generator 810, the steam generator 810 can be stably seated on the base cover 360.
[0235] In addition, since the steam generator 810 is disposed above the circulation duct 320 and the distance to the inner case 200 is shorter, condensation of the steam generated by the steam generator 810 before it reaches the inner case 200 can be minimized.
[0236] FIG. 10 shows the detailed structure of the steam supply section.
[0237] Referring to FIG. 10(a), the steam supply unit 800 may include a steam generator 810 that receives and stores water for generating steam, and a steam heater 840 that is housed in the steam generator 810 and heats the water to generate steam.
[0238] The steam generator 810 may be provided in a case shape that forms a space for accommodating the steam heater 840 .
[0239] For example, the steam generator 810 may be a case-shaped device with an open top, and may house the steam heater 840 therein.
[0240] The steam supply unit 800 may further include a case cover 820 coupled to the steam generator 810 to prevent the steam heater 840 from being exposed to the outside and to prevent the water from leaking out.
[0241] The case cover 820 may be provided with a water level sensor 850 for detecting the water level in the steam generator 810 and a steam sensor 860 for detecting the temperature inside the steam generator 810 or detecting whether steam is generated inside the steam generator 810.
[0242] Referring to FIG. 10( b ), the steam generator 810 may include a case body 811 that stores the water and provides a space to house a steam heater 840 .
[0243] The case body 811 has an open top, so that various components can be easily installed inside the case body 811 .
[0244] The case body 811 may have a heater insertion hole 8111 through which one side is penetrated and into which the heater 840 can be inserted or pulled out.
[0245] The case body 811 may include a recovery pipe 814 therein through which water for generating steam is supplied.
[0246] The recovery pipe 814 may be provided to discharge water contained in the case body 811 to the outside.
[0247] The recovery pipe 814 can be maintained in a closed state by a shutoff valve 8141 so that it can be opened only when removing residual water inside the steam generator 810, and can include a shutoff clip 8142 that maintains the shutoff valve 8141 connected to the recovery pipe 814 to prevent the shutoff valve 8141 from being accidentally separated.
[0248] Therefore, when the steam generator 800 is repaired or when the steam generator 800 is to be prevented from freezing and breaking, water inside the steam generator 800 can be discharged through the recovery pipe 814 .
[0249] Of course, the recovery pipe 814 can be configured to receive water from the water supply tank 30. Details will be described later.
[0250] Meanwhile, a heater fixing part 830 for supporting or fixing the steam heater 840 may be installed inside the case body 811. The heater fixing part 830 may include a fixing clip 831 for fixing the steam heater 840, and a clip fastening member 833 for fixing the fixing clip 831 to the case body 811.
[0251] The fixing clip 831 may be configured to house or cover at least a portion of the steam heater 840 .
[0252] Meanwhile, the steam supply unit 800 may include a water supply pipe 815 through which water is supplied. The water supply pipe 815 may be configured to communicate with the water supply tank 30 so that water can be supplied.
[0253] The water supply pipe 815 may be provided in the case cover 820 or disposed on the top of the steam generator 810. This prevents water from flowing back through the water supply pipe 815.
[0254] The steam supply unit 800 may include a steam pipe 813 that discharges steam generated by driving the steam heater 840 to the outside. The steam pipe 813 is also provided on the upper part of the case cover 820, and can prevent water from being arbitrarily discharged into the steam pipe 813.
[0255] The steam pipe 813 can be connected to the steam hole 233 of the inner case 200 .
[0256] The case cover 820 may have a water level sensor hole 854 in which the water level sensor 850 is installed.
[0257] The water level sensor 850 may include one or more contact protrusions 852 that are inserted into the water level sensor hole 854 and immersed in water to detect the water level, and a sensor body 851 that is coupled to the water level sensor hole 854 or supported by the case cover 820 to maintain the contact protrusions 852 in a floating state inside the steam generator 810.
[0258] The sensor body 851 may be coupled to the case cover 820 via a sensor fastening member 853 .
[0259] Meanwhile, the case cover 820 may have an insertion hole 864 in which the steam sensor 860 is installed. The steam sensor 860 may include a detection device 861 inserted into the insertion hole 864 and detecting whether steam is generated inside the steam generator 810, a support 863 for fixing the detection device 861 to the case cover 820, and a connecting member 862 for connecting the support 863 to the case cover 820.
[0260] The detector 861 is provided as a humidity sensor or a temperature sensor, and can detect whether steam is generated inside the steam generator 810 .
[0261] Meanwhile, the case cover 820 may include a cover hook 821 that extends forward and is coupled to the base cover 860 .
[0262] In addition, a fixing protrusion 822 for fixing the lower part of the inner case 200 or a separate steam discharge part 900 may be provided at the rear of the case cover 820 .
[0263] The steam heater 840 may be configured to be inserted into the heater insertion hole 8111, accommodated in the steam generator 810, and supplied with power to heat water.
[0264] The steam heater 840 may be provided as a sheath heater, and may be controlled by the control unit 700 to be repeatedly turned on and off.
[0265] The steam heater 840 may include a first heater 841 supplied with a first power to heat water, and a second heater 842 supplied with a power smaller than the first power to heat water.
[0266] As a result, the second heater 842 can be configured to heat a smaller amount of water and produce more steam than the first heater 841.
[0267] The first heater 841 and the second heater 842 may be configured to consume a portion of the maximum heater power allowed for the steam heater 840 in the laundry treatment device. That is, if the first heater 841 is configured to consume a portion of the maximum heater power, the second heater 842 may be configured to consume the remainder of the maximum heater power.
[0268] For example, if the maximum heater power allowed for the steam heater 840 is 1500 W, the first heater 841 may be configured to consume 880 W, and the second heater 842 may be configured to consume 600 W. In this way, 20 W may be allocated less in consideration of errors, etc.
[0269] Of course, the steam heater 840 may include three or more heaters. For example, the first heater 841, the second heater 842, and the third heater 843 may be configured to share and consume the maximum amount of heater power.
[0270] Hereinafter, the steam heater 840 will be described based on the case where the steam heater 840 is composed of the first heater 841 and the second heater 842.
[0271] The first heater 841 and the second heater 842 may be formed of a U-shaped metal tube.
[0272] The steam heater 840 may include a heater sealer 843 that fixes the first heater 841 and the second heater 842 and seals the heater insertion hole 8111, and may include a terminal portion 844 that supplies current to the first heater 841 and the second heater 842.
[0273] The terminal unit 844 may include a first terminal 844 a for supplying current to the first heater 841 and a second terminal 844 b for supplying current to the second heater 842 .
[0274] The first heater 841 and the second heater 842 may be disposed at the same height, and therefore, the first heater 841 and the second heater 842 may be configured to heat water at the same water level to generate steam.
[0275] Thus, the control unit 700 can adjust the amount of steam generated and the amount of power consumed by using both or selectively the first heater 841 and the second heater 842.
[0276] FIG. 11 shows the inside of the steam generator.
[0277] The steam generator 810 may include a heating space 817 for storing water therein and accommodating a steam heater 840 .
[0278] In addition, water for generating steam can be supplied to the steam generator 810 through a water supply hose 8151 connected to the water supply pipe 815 .
[0279] Meanwhile, the steam generated by driving the steam heater 840 in the steam generator 810 can be discharged to the outside of the steam supply unit 800 through the steam discharge pipe 813 and the steam hose 8131 .
[0280] The steam hose 8131 can communicate with the steam hole 233 of the inner case 200 .
[0281] Meanwhile, the steam generator 810 may include a partition wall 812 that can separate the heating space 817 from the water level sensor 850. That is, the partition wall 812 is configured to separate the steam heater 840 from the water level sensor 850, and may be disposed biased toward one side of the case body 811.
[0282] The water level sensor 850 may be disposed between the separating partition 812 and the inner surface of the case body 811 .
[0283] This prevents the vibrations of water that occur when the water boils from being transmitted to the water level sensor 850, and also prevents the heat generated by the steam heater 840 from being directly transmitted to the water level sensor 850.
[0284] FIG. 12 shows a steam supply unit in which the steam heater is installed.
[0285] 12(a), the steam sensor 860 may be disposed above the steam heater 840 and may be configured to detect the temperature inside the steam generator 810. Thus, the steam sensor 860 may detect that steam is generated when the water reaches 100°C or a high temperature.
[0286] The steam heater 840 is supported by the support clip 832, and can prevent the steam heater 840 from contacting the bottom surface of the steam generator 810, etc.
[0287] In addition, the upper portion is enclosed by the fixing clip 831, so that the position where the steam heater 840 is disposed can be prevented from being changed.
[0288] Referring to FIG. 12(b), the heater sealer 844 of the steam heater 840 may have a first support hole 8441 through which the first heater 841 passes and is supported, and a second support hole 8442 through which the second heater 842 passes and is supported.
[0289] A first length L1 by which the first support hole 8441 is spaced from the bottom surface of the steam generator 810 and a second length L2 by which the second support hole 8442 is spaced from the bottom surface of the steam generator 810 may be the same as each other.
[0290] Although the first support hole 8441 and the second support hole 8442 have different diameters, they may be installed at the same height.
[0291] As a result, the first heater 841 and the second heater 842 can heat water at the same water level to generate steam.
[0292] FIG. 13 shows in detail the steam supply structure of the clothes treating device of the present invention.
[0293] The steam generated in the steam generator 810 can be directly supplied to the inner case 200 through the steam pipe 813 .
[0294] However, if steam is directly supplied into the inner case 200 through the steam pipe 813, the water contained in the steam generator 810 may also be supplied into the inner case 200.
[0295] In addition, the water heated by the steam generator 810 heats the bottom surface of the inner case 200, which may cause thermal damage to the inner case 200.
[0296] To prevent this, the steam supply unit 800 of the present invention may further include a steam nozzle 900 that receives the steam generated by the steam generator 810 and supplies it to the inner case 200 .
[0297] The steam nozzle 900 may be disposed at a distance from the steam generator 810 and configured to supply only the steam generated by the steam generator 810 and not the water contained in the steam generator 810.
[0298] For example, the steam nozzle 900 may be disposed above the steam generator 810 and connected to the steam wand 813. As a result, the steam generated in the steam generator 810 rises due to a density difference and is supplied to the steam nozzle 900 along the steam wand 813, and water contained in the steam generator 810 may not flow into the steam wand 813 or the steam nozzle 900 due to gravity.
[0299] The steam nozzle 900 may be disposed between the bottom surface of the inner case 200 and the steam generator 810 and communicate with the steam hole 233 .
[0300] Meanwhile, the steam supplier 800 of the present invention is provided to generate steam by receiving water from the water supply tank 30 .
[0301] For this purpose, the laundry treatment device of the present invention may further include a water supply pump 880 for supplying water contained in the water supply tank 30 to the steam supply unit 800 .
[0302] The steam supply unit 800 may further include a supply pipe 890 that guides water contained in the water supply tank 30 to the water supply pump 880 .
[0303] In addition, the laundry treatment device of the present invention may further include a water supply pipe 815 for guiding water discharged from the water supply pump 880 to the steam supply unit 800. The water supply pipe 815 may be provided in the form of a water supply hose 8151 made of rubber or the like.
[0304] As a result, the water supply pump 880 may be configured to receive water from a supply pipe 890 connected to the water supply tank 30. Also, the water supply pump 880 may be configured to discharge water to the steam supplier 800 through a water supply pipe 881.
[0305] The steam supply unit 800 may include a water supply pump 880 that provides power to supply water contained in the water supply tank 30 to the steam generator 810 .
[0306] The supply pipe 890 may be provided as a hose connecting the water supply tank 30 and the water supply pump 880 , and the water supply pipe 881 may be provided as a hose connected to the water supply pump 880 .
[0307] Meanwhile, the water supply pipe 815 may be provided to directly connect the water supply pump 880 and the steam generator 810. Thus, water supplied from the water supply pump 880 may be directly supplied to the steam generator 810 and heated by the steam heater 840 to generate steam. The steam may be supplied to the steam nozzle 900 through the steam pipe 813 and transferred to the inner case 200.
[0308] However, as shown in FIG. 15, the water supply pipe 815 can be provided to directly connect the water supply pump 880 and the steam nozzle 900 .
[0309] In other words, the clothing treatment device of the present invention can be configured to supply water contained in the water supply tank 30 to the steam nozzle 900 instead of the steam generator 810. Water supplied from the water supply pump 880 can be supplied directly to the steam nozzle 900.
[0310] The water supply pump 880 does not have to be directly connected to the steam generator 810. The water supply pump 880 is considered to be in communication with the steam generator 810 via the steam nozzle 900.
[0311] The steam nozzle 900 may be supplied with water stored in the water supply tank 30 through the water supply pump 880. The water supplied to the steam nozzle 900 may be transferred to the steam generator 810.
[0312] Since the steam nozzle 900 is disposed above the steam generator 810 , water supplied to the steam nozzle 900 can be automatically supplied to the steam generator 810 .
[0313] As a result, the steam nozzle 900 may be provided to transfer water contained in the water supply tank 30 via the water supply pump 880 to the steam generator 810 .
[0314] The steam supply unit 900 may further include a recovery pipe 815 connecting the steam nozzle 900 and the steam generator 810. The recovery pipe 815 may supply water supplied to the steam nozzle 900 and temporarily stored therein to the steam generator 810.
[0315] Therefore, the steam pipe 813 through which steam flows into the steam nozzle 900 and the recovery pipe 815 through which water is discharged from the steam nozzle 900 can be provided as separate flow paths.
[0316] Therefore, the water supplied from the steam nozzle 900 can be prevented from blocking the flow of steam supplied from the steam generator 810 .
[0317] Meanwhile, the recovery pipe 815 may be configured in a U-shape. That is, a portion of the recovery pipe 815 may be positioned lower than both ends of the recovery pipe 815. As a result, a certain amount of water may be accumulated in the recovery pipe 815 like a water trap, and the steam and water supplied from the steam generator 810 may be prevented from flowing back through the recovery pipe 815.
[0318] The steam pipe 813 may include a steam hose 8131 connecting the steam nozzle 900 and the steam generator 810. The steam hose 8131 may be made of a rubber material.
[0319] The recovery pipe 815 may be provided separately from the steam pipe 813 and may be spaced apart from the steam pipe 813. The recovery pipe 815 may include a recovery hose 8151 that connects the steam nozzle 900 and the steam generator 810. The recovery hose 8151 may be made of a rubber material.
[0320] The steam generator 810 can receive and store the water supplied to the steam nozzle 900. Since the steam generator 810 is not directly connected to the water supply pump 880, there is no possibility that the water flowing into the steam generator 810 will flow back to the water supply pump 880.
[0321] In addition, since the steam nozzle 900 is disposed above the steam generator 810 and is connected to the steam generator 810 via the recovery pipe 815, the water supplied to the steam nozzle 900 can be automatically supplied to the steam generator 810 by gravity. As a result, there is no possibility that the water supplied to the steam nozzle 900 from the water supply pump 880 will flow back to the water supply pump 880.
[0322] As a result, a check valve can be omitted between the water supply pump 880 and the steam nozzle 900 or the steam generator 810. Therefore, the water supply pipe 881 can be configured as a single water supply hose. This simplifies the flow path for supplying water to the steam supply unit 900, and accordingly reduces the possibility of water leakage in the flow path.
[0323] In addition, a large amount of water can be supplied to the steam nozzle 900 at a considerable pressure through the water supply pump 880. As a result, foreign matter and bacteria remaining in the steam nozzle 900 can be washed away by the water supplied to the steam nozzle 900 and then washed into the steam generator 810. Therefore, the steam nozzle 900 can be kept clean at all times, and the flow of supplied steam can be prevented from being obstructed.
[0324] Meanwhile, when the steam supplied from the steam nozzle 900 is condensed, the condensed water can re-flow into the steam generator 810 through the recovery pipe 815. That is, the condensed water generated in the steam nozzle 900 can be recovered in the steam generator 810 in the same direction as the water supplied from the water supply pump 880 and reused as water for generating the steam. Therefore, the laundry treatment device of the present invention can prevent the water level in the water supply tank 30 from dropping suddenly, and can also prevent water from being wasted.
[0325] FIG. 14 is a diagram illustrating the flow path structure of the steam supply unit of the present invention.
[0326] Water supplied from the water supply pump 880 can be supplied to the steam nozzle 900 along the water supply pipe 881 .
[0327] The steam nozzle 900 can supply the supplied water to the steam generator 810 .
[0328] The steam generator 810 can be supplied with water via the return pipe 815 .
[0329] In the steam generator 810 , water is heated by the steam heater 840 to generate steam, and the steam can be supplied to the steam nozzle 900 along the steam pipe 813 .
[0330] At this time, the recovery pipe 815 and the steam pipe 813 may be disposed in the steam generator 810 separately from each other.
[0331] The steam condensed in the steam nozzle 900 can re-enter the steam generator 810 through a recovery pipe 815 .
[0332] The steam generator 810 may not have any hoses connected to the outside except for the recovery pipe 815 and the steam pipe 813 connected to the steam nozzle 900. That is, the water supply pump 880 may not be directly connected to the steam generator 810, and the hose connecting the water supply pump 880 and the steam generator 810 may be omitted.
[0333] Therefore, the clothing treatment device of the present invention only needs to include the water supply pipe 881, the recovery pipe 815, and the steam pipe 813 as steam-related flow paths, thereby simplifying the flow path structure.
[0334] Also, the steam nozzle 900 may be disposed above the steam generator 810. Therefore, all of the water supplied to the steam nozzle 900 can be guided to the steam generator 810 without a separate check valve.
[0335] Therefore, when water supplied from the water supply pump 880 is supplied to the steam nozzle 900, all of the water supplied to the steam nozzle 900 is guided to the steam generator 810, thereby preventing water from flowing back from the steam nozzle 900 to the water supply pump 880.
[0336] Therefore, a check valve between the water supply pump 880 and the steam nozzle 900 can be omitted.
[0337] Furthermore, since there is no need to provide a check valve in the water supply pipe 881, there is no need to provide multiple water supply pipes 881, and one hose can be provided instead. As a result, not only is the flow path structure further simplified, but installation and maintenance of the flow path are also made easier, and the possibility of water leakage can be further reduced.
[0338] FIG. 15 shows the flow path structure of the steam nozzle.
[0339] The steam nozzle 900 may include a supply container 910 that receives steam from the steam case 810 or water from the water supply pump 880 and stores the water therein.
[0340] The supply container 910 may be configured in a case shape with an internal space for receiving and storing water or steam.
[0341] The water supply pipe 881 may be connected to the supply container 910 at a position higher than the bottom of the supply container 910. For example, the water supply pipe 881 may be connected to the side of the supply container 910. This prevents water supplied to the supply container 910 from flowing back into the water supply pipe 881.
[0342] The water supply pipe 881 may be connected to the supply container 910 at a position higher than the return pipe 815. For example, the return pipe 815 may be disposed with one end connected to the bottom of the supply container 910 and the other end connected to the steam generator 810. Thus, water supplied from the water supply pipe 881 can automatically flow into the return pipe 815.
[0343] Also, the recovery pipe 815 may be U-shaped so as to accommodate a certain amount of water therein.
[0344] Meanwhile, the recovery pipe 815 may be disposed adjacent to the water supply pipe 881. Thus, the water supplied through the water supply pipe 881 may not remain in the supply container 910 but may quickly flow into the steam case 810.
[0345] Meanwhile, one end of the steam pipe 813 may be connected to the lower part of the supply container 910, and the other end may be connected to the upper part of the steam generator 810 or the steam cover 820. Thus, steam generated in the steam generator 810 can be automatically supplied to the supply container 910 due to the difference in density.
[0346] The steam wand 813 may be connected to the supply container 910 at a position higher than the recovery pipe 815. Also, the steam wand 813 may be disposed at a position farther from the water supply pipe 881 than the recovery pipe 815.
[0347] As a result, the water supplied to the supply container 910 does not flow back to the steam pipe 813 and can be supplied to the recovery pipe 815 in larger amounts.
[0348] The steam wand 813 may be coupled to the bottom of the supply container 910 .
[0349] The bottom of the supply container 910 may be lower at a portion where the recovery pipe 815 is connected and higher at a portion where the steam pipe 813 is connected. To this end, the bottom of the supply container 910 may have a step or may be sloped.
[0350] The steam nozzle 900 may further include a container cover 920 coupled to an upper portion of the supply container 910. The container cover 920 may include a steam injection hole 923 formed through an upper portion thereof. The steam injection hole 923 may be formed to communicate with the interior of the inner case 200.
[0351] The supply container 910 may be provided in the form of a box with an open top, and the container cover 920 may be provided to cover the top of the supply container 910 .
[0352] The steam supplied through the steam pipe 813 can be discharged through the steam injection hole 923 and supplied into the inner case 200 .
[0353] The steam wand 813 may be disposed between the steam injection hole 923 and the inner surface of the supply container 910. The steam injection hole 923 may be disposed between the water supply pipe 881 and the steam wand 813, or between the recovery pipe 815 and the steam wand 813. Thus, steam that is not discharged through the steam injection hole 923 and is condensed can be discharged from the recovery pipe 815 without remaining inside the supply container 910.
[0354] The steam injection hole 923 may be disposed at the center of the container cover 920 in the width direction.
[0355] The container cover 920 may be coupled to the supply container 910 by a hook coupling method, etc., so that a separate fastening member for coupling the container cover 920 to the supply container 910 can be omitted.
[0356] Meanwhile, the supply container 910 has an open top, which is convenient for installing various shapes and structures inside, and the container cover 920 is convenient for installing various structures below.
[0357] With respect to the steam injection hole 932 , the water supply pipe 881 and the recovery pipe 815 are disposed on one side of the supply container 910 , and the steam pipe 813 is disposed on the other side of the supply container 910 .
[0358] That is, the water supply pipe 881 and the recovery pipe 815 are disposed adjacent to each other, and the steam pipe 813 is disposed at a position farther away from the water supply pipe 881 than the recovery pipe 815 is.
[0359] As a result, water moving through the water supply pipe 881 can be supplied to the supply container 910 along direction I. The water supplied to the supply container 910 is immediately discharged through a recovery pipe 815 along direction II and can be supplied to the steam generator 810. Steam supplied from the steam pipe 813 is supplied to the supply container 910 along direction III and discharged from the steam injection hole 932, and the condensed water is discharged through a recovery pipe 815 along direction II and can be re-supplied to the steam generator 810.
[0360] An embodiment of the moving hanger 1000 will be described in detail below.
[0361] The moving hanger 1000 may be configured to move linearly back and forth inside the inner case 200. Thus, the clothes can be swung while moving linearly back and forth inside the inner case 200.
[0362] The moving hanger 1000 can periodically shake clothes at various frequencies.
[0363] For example, the moving hanger 1000 may have a structure similar to that of Korean Patent Registration No. 10-1285890.
[0364] In addition, the moving hanger 1000 may be configured to swing the clothes while rotating them back and forth inside the inner case.
[0365] That is, the moving hanger 1000 may have any structure as long as it can swing the clothes inside the inner case in the clothes treating device of the present invention.
[0366] The structure of the moving hanger 1000 that rotates the clothes back and forth will be described below.
[0367] FIG. 16 shows the upper structure of the inner case 200 of the clothing treatment device of the present invention.
[0368] The moving hanger 1000 of the clothing treatment device of the present invention may include a power transmission unit 1400 disposed on the upper part of the inner case 200 to swing the hanger 1900.
[0369] A hanging part 1700 on which the hanger 1900 is placed or hung may be provided at a lower part of the power transmission part 1400 .
[0370] As a result, when the power transmission unit 1400 moves, the hanging unit 1700 moves, and the hanger unit 1900 hung on the hanging unit 1700 swings, thereby providing an effect of beating the clothes.
[0371] A plurality of power transmission units 1400 may be provided, and a plurality of hanging units 1700 connected to the power transmission units 1400 may also be provided. Thus, a number of clothes corresponding to the number of power transmission units 1400 can be hung in the inner case 200 and refreshed.
[0372] The moving hanger 1000 may further include a driving unit 1200 that provides power for moving the power transmission unit 1400 .
[0373] The driving unit 1200 may be exposed to the inside of the inner case 200 as long as it can transmit power to the power transmission unit 1400. However, since the driving unit 1200 is configured to be operated by receiving electrical energy, it is preferable that it is shielded from exposure to steam or hot air.
[0374] Therefore, the driving unit 1200 is disposed between the upper surface of the inner case 200 and the cabinet 100 , and is prevented from being exposed to the receiving space 220 .
[0375] The power transmission part 1400 can transmit power from the driving part 1200 through the inner case 200 to the hanging part 1700 .
[0376] The power transmission unit 1400 may extend into the receiving space 220 by passing through an upper surface of the inner case 200. A lower end of the power transmission unit 1400 may be exposed to the receiving space 220, and an upper end of the power transmission unit 1400 may be exposed above the inner case 200.
[0377] The power transmission part 1400 may be provided in the shape of a rod, a tube, or a plate, the length of which is longer than the thickness.
[0378] Meanwhile, the upper surface of the inner case 200 can support the weight of the power transmission unit 1400 and the driving unit 1200. The power transmission unit 1400 moves when clothes are hung on it, and the driving unit 1200 is also configured to be relatively heavy. Therefore, in order to stably install the moving hanger 1000 on the upper surface of the inner case 200, the clothing disposal device 1 of the present invention may further include a support unit 1800.
[0379] The support part 1800 is disposed on the upper part of the inner case 200 and may be coupled to and supported by the cabinet 100. The support part 1800 may be made of a metal material that is durable and resistant to deformation.
[0380] The power transmission unit 1400 and the driving unit 1200 may be placed on the support unit 1800 and disposed on the upper part of the inner case 200. The power transmission unit 1400 may extend into the receiving space 220 through the support unit 1800.
[0381] Meanwhile, the driving unit 1200 includes a motor that rotates a rotation shaft, and the driving unit 1200 may be configured to drive the power transmission unit 1400 by the power generated by the rotation of the rotation shaft.
[0382] However, it may be difficult to oscillate the power transmission part 1400 with a sufficient displacement amount by simply rotating the rotation shaft at that position.
[0383] Therefore, the moving hanger 1000 may further include a displacement generating unit 1300 coupled to a rotation shaft rotated by the motor, which generates a sufficient displacement (position change amount) for the power transmission unit 1400 to operate.
[0384] The displacement generating unit 1300 may be connected or coupled to the driving unit 1200 .
[0385] For example, the displacement generating unit 1300 may be configured to transmit the power of the driving unit 1200 to the power transmitting unit 1400 .
[0386] The displacement generating unit 1300 may include an eccentric shaft that rotates along a path larger than the diameter of the rotation shaft. The eccentric shaft may be directly connected to the rotation shaft of the driving unit 1200, or may be eccentrically connected to or extended from a power shaft 1240 that rotates with the rotation shaft.
[0387] The displacement generating unit 1300 may have any configuration as long as it can generate a displacement that causes the power transmission unit 1400 to reciprocate within a predetermined range. The detailed structure will be described later.
[0388] When the driving unit 1200 is operated, the power generated at the rotation shaft generates a displacement of the displacement generating unit 1300, and the power transmission unit 1400 can operate according to the displacement of the displacement generating unit 1300.
[0389] The displacement generating unit 1300 can directly move the power transmission unit 1400, but can also move the power transmission unit 1400 by an additional configuration.
[0390] The moving hanger 1000 of the present invention may be provided to reciprocate the power transmission unit 1400.
[0391] In addition, the moving hanger 1000 of the present invention may be provided to rotate the power transmission unit 1400. Specifically, the moving hanger 1000 may be provided to rotate the power transmission unit 1400 back and forth within a predetermined angle range, rather than to move the power transmission unit 1400 back and forth in a straight line.
[0392] The power transmission unit 1400 may be configured to rotate clockwise or counterclockwise from a fixed position, and clothes hung on the power transmission unit 1400 may also rotate clockwise or counterclockwise. The power transmission unit 1400 is rotated by the moving hanger 1000, but may be moved to the left or right side so as not to move.
[0393] Even if the clothes rotate inside the inner case 200 due to the power transmission unit 1400, the movement of the center of gravity inside the inner case 200 can be limited. Therefore, even if the moving hanger 1000 is operated, the vibration generated inside the inner case 200 can be drastically reduced, and the generation of noise can also be minimized.
[0394] To this end, the moving hanger 1000 may further include a reciprocating rotation unit 1500 that converts continuous rotational energy generated in the driving unit 1200 or the displacement generating unit 1300 into reciprocating rotational motion of the power transmission unit 1400.
[0395] The reciprocating rotation unit 1500 may be provided to connect the displacement generating unit 1300 and the power transmitting unit 1400 to each other. The reciprocating rotation unit 1500 may be provided to connect the displacement generating unit 1300 and the power transmitting unit 1400 to each other above the inner case 200. The reciprocating rotation unit 1500 blocks exposure to the receiving space 220, thereby preventing the clothing from being damaged by the reciprocating rotation unit 1500.
[0396] Meanwhile, the moving hanger 1000 may be provided to rotate only one of the plurality of power transmission units 1400 back and forth.
[0397] However, when only one power transmission unit 1400 rotates, the clothes hung on the rotating power transmission unit may collide with and be damaged by the clothes hung on the other power transmission units 1400. In addition, the impact may be transmitted to the moving hanger 1000, causing damage to the moving hanger 1000.
[0398] Therefore, it is preferable that the moving hanger 1000 is configured to rotate all of the plurality of power transmission parts 1400.
[0399] The moving hanger 1000 can rotate the plurality of power transmission units 1400 together. The moving hanger 1400 can be provided to rotate the plurality of power transmission units 1400 at the same angle simultaneously. This makes it possible for the clothing treatment device of the present invention to prevent the power transmission units 1400 from colliding with each other.
[0400] The power generated by the driving unit 1200 is directly transmitted to the plurality of power transmission units 1400, which is advantageous in terms of rotating all of the power transmission units 1400.
[0401] However, if the driving unit 1200 is configured to directly transmit power to each power transmission unit 1400, the structure connecting the driving unit 1200 and all the power transmission units 1400 may become complicated.
[0402] In addition, if a plurality of driving units 1200 are provided and a plurality of configurations for connecting all of the power transmission units 1400 to the driving units 1200 are provided, an excessive load may be applied to the inner case 200 or the support unit 1800. Furthermore, there is a risk of causing inconvenience in having to control a plurality of driving units 1200.
[0403] Furthermore, if the displacement generating unit 1300 and the reciprocating rotating unit 1500 are connected so as to transmit the power transmitted from one driving unit 1200 to each of all power transmission units 1400, the arrangement and structure of the displacement generating unit 1300 and the reciprocating rotating unit 1500 will become complex, which may reduce reliability.
[0404] Therefore, the moving hanger 1000 can be provided such that one driving unit 1200 generates power to rotate a plurality of power transmission units 1400 .
[0405] In addition, the moving hanger 1000 may be configured such that the power generated by the driving unit 1200 is transmitted preferentially to some of the power transmission units 1400 or some of the reciprocating rotation units 1500, and the remaining power transmission units 1400 or remaining reciprocating rotation units 1500 receive the power secondarily.
[0406] For example, the reciprocating rotation unit 1500 may be configured to receive power transmitted from the driving unit 1200 or the displacement generating unit 1300 and transmit it to a part of the power transmission unit 1400. That is, the moving hanger 1000 is configured to transmit the power generated in the driving unit 1200 intensively to one reciprocating rotation unit 1500, which allows for a simple design of the power transmission structure and minimizes power loss.
[0407] The moving hanger 1000 of the present invention can be configured to transmit the power transmitted from the driving unit 1200 to one reciprocating rotating unit 1500 and rotate a specific power transmission unit 1400 connected to the reciprocating rotating unit 1500.
[0408] In addition, the moving hanger 1000 may further include a connecting part 1600 that is provided to transmit the power transmitted to a specific power transmission part 1400 to another power transmission part 1400 .
[0409] For example, the connecting part 1600 may be provided to connect the plurality of power transmission parts 1400 to each other, so that when any one of the power transmission parts 1400 rotates, the connecting part 1600 can rotate all of the plurality of power transmission parts 1400.
[0410] FIG. 17 shows how the moving hanger of the present invention operates.
[0411] 17(a), when the driving unit 1240 is operated, the power transmission unit 1400 can be rotated rightward by the reciprocating rotation unit 1500. At this time, the power transmission unit 1400 connected to the connecting unit 1600 can also be rotated rightward.
[0412] 17(b), when the driving unit 1200 is further operated, the power transmission unit 1400 can be rotated leftward by the reciprocating rotation unit 1500. At this time, the power transmission unit 1400 connected to the connecting unit 1600 can also be rotated leftward.
[0413] By repeating this process, the power transmission unit 1400 can rotate left and right.
[0414] In this case, the power transmission unit 1400 may be configured to rotate left and right while being fixed at a fixed position, and may be fixed to the support unit 1800 so that the position of the power transmission unit 1400 does not change forward, backward, left and right when it rotates.
[0415] The power transmission unit 1400 may be fixed so that its position does not move based on the vertical, front-rear, and width directions.
[0416] However, the power transmission unit 1400 may be configured to rotate left and right around the vertical or height direction of the extension of the power transmission unit as a rotation axis. As a result, when the driving unit 1200 is driven, the hanging unit 1700 rotates left and right around the power transmission unit 1400 as an axis, and there is no positional movement.
[0417] 17(c), the hanger unit 1900 may include a hook unit 1910 that is hung on the hanging unit 1700, and a seat unit 1950 that is connected to the hook unit 1910. The seat unit 1950 may have a surface unit 950 that prevents clothes from slipping.
[0418] The seating portions 1950 may be provided symmetrically with respect to the hook portion 1910. The hanger portion 1900 may be hung on the hanging portion 1700 so that the seating portions 1950 are arranged in the front-rear direction.
[0419] When the power transmission unit 1400 rotates to the left, the left side of the seating unit 1950 of the hanger unit 1900 may rotate leftward and the right side of the seating unit 1950 may rotate rightward based on the hook unit 1910. In this case, the angle (I) at which the left side of the seating unit 1950 rotates may be the same as the angle (θ) at which the right side of the seating unit 1950 rotates, and the distance at which the left side of the seating unit 1950 moves may be the same as the distance at which the right side of the seating unit 1950 moves.
[0420] As a result, the weight and force moving to the left side based on the hanger part 1900 are the same as the weight and force moving to the right side, and can cancel each other out.
[0421] Similarly, even if the power transmission part 1400 rotates to the right, the weight and force moving to the left side relative to the hanger part 1900 as a result is the same as the weight and force moving to the right side, and they can cancel each other out.
[0422] As a result, even when the power transmission unit 1400 rotates, the forces applied to the hanger unit 1900 are offset with each other, thereby minimizing the vibration, excitation force, and inertia force generated in the hanger unit 1900 itself. As a result, the inertia force generated in the plurality of power transmission units 1400 is minimized, and the vibration and noise generated in the entire moving hanger 1000 are minimized, and the generation of vibration and noise in the entire garment processing device 1 can be drastically reduced.
[0423] As a result, even if the driving unit 1200 rotates at maximum output, the moving hanger 1000 or the entire clothing processing device 1 does not vibrate significantly.
[0424] Instead, the surfaces of the clothes hung on the hanger unit 1900 are hit by rotating left and right, so a large hitting force can be ensured.
[0425] As described above, the power transmission unit 1400 is installed to penetrate the inner case 200 and can rotate back and forth in clockwise and counterclockwise directions by transmitting power. As a result, the power transmission unit 1400 can rotate back and forth left and right while being fixed in position at the top of the inner case 200. The power transmission unit 1400 is fixed so that its position cannot be changed in the up, down, left, or right directions. In addition, not only the top but also the bottom of the power transmission unit 1400 are fixed so that their positions cannot be changed in the up, down, left, or right directions.
[0426] That is, the power transmission unit 1400 can rotate back and forth at a fixed angle in less than one revolution with the center of rotation fixed.
[0427] As a result, no matter how fast the power transmission part 1400 rotates, the hanger part 1900 remains fixed in position and one end rotates or moves to one side and the other end to the other side, so that the forces and vibrations transmitted to the power transmission part 1400 can cancel each other out.
[0428] Therefore, vibrations and noises generated by the power transmission part 1400, the hook part 1700, and the hanger part 1900 inside the inner case 200 can be minimized.
[0429] As a result, the clothing treatment device of the present invention can rotate the driving unit 1200 at a higher RPM and reciprocate the power transmission unit 1400 at a higher frequency, thereby allowing the clothing treatment device of the present invention to shake the clothing more strongly.
[0430] In addition, the moving hanger 1000 of the present invention is provided with a power transmission unit 1400 that rotates back and forth clockwise or counterclockwise at its position. Therefore, as described above, no matter how fast the hanger unit 1900 rotates, the vibrations or inertial forces generated in the hanger unit 1900 and the clothes can be canceled out when transmitted to the power transmission unit 1400.
[0431] As a result, even if the driving unit 1200 of the moving hanger 1000 of the present invention is increased to a certain RPM or more, the moving hanger 1000 will not be damaged, and vibrations and noises exceeding the limit value can be suppressed from occurring in the clothing processing device.
[0432] Therefore, the clothing treatment device of the present invention can drive the drive unit 1200 faster than a clothing treatment device using a conventional moving hanger, and can drive the power transmission unit 1400 at a higher frequency to shake the clothing more strongly.
[0433] As a result, the clothing treatment device of the present invention can more reliably remove foreign matter attached to the clothing and more effectively remove wrinkles from the clothing through the moving hanger 1000. In addition, the clothing treatment device of the present invention can vibrate the clothing at a higher speed to expose it to the supplied steam more.
[0434] In addition, the clothes treating device of the present invention can freely adjust the RPM of the driving unit 1200 and adjust the driving frequency or driving cycle of the power transmission unit 1400 according to the course.
[0435] FIG. 18 shows one embodiment of a moving hanger 1000 of the present invention.
[0436] The moving hanger 1000 of the present invention can be configured to transmit the power of the driving unit 1200 to only one of the multiple power transmission units 1400, and to transmit the power transmitted to a specific power transmission unit 1400 via the connecting unit 1600 to the remaining power transmission units 1400.
[0437] The displacement generating unit 1330 or the reciprocating rotating unit 1500 may be configured to transmit power generated in one driving unit 1200 to one power transmitting unit 1400 in a concentrated manner. The connecting unit 1600 may transmit power transmitted to a specific power transmitting unit 1400 to all power transmitting units 1400.
[0438] The connecting part 1600 may be configured as a rigid body so that its length is not variable, and may be configured to completely connect all of the power transmission parts 1400 .
[0439] As a result, all the power transmission parts 1400 can rotate simultaneously in the same direction and at the same angle when the connecting part 1600 moves. As a result, the moving hanger 1000 of the present invention can rotate multiple power transmission parts 1400 back and forth at the same angle simultaneously or at one time using one driving part 1200.
[0440] The moving hanger 1000 may include a driving unit 1200 fixed to the upper part of the inner case 200 and supplying power to move the power transmission unit, a plurality of reciprocating rotating units 1500 respectively coupled to the plurality of power transmission units 1400, receiving power from the driving unit 1200, and rotating so that the rotation direction repeatedly changes, and a connecting unit 1600 configured to connect the plurality of reciprocating rotating units to each other.
[0441] The connecting part 1600 may include a link bar that connects the plurality of reciprocating rotating parts 1500 and rotates the plurality of reciprocating rotating parts 1500 together.
[0442] The connecting portion 1600 may be provided singly.
[0443] The connecting unit 1600 may be provided to connect all of the power transmission units 1400 together.
[0444] However, when the connecting part 1600 is provided to connect the reciprocating rotating part 1500, the connecting part 1600 can be installed above the supporting part 1800, and thus exposure to the inside of the inner case 200 can be prevented.
[0445] The connecting unit 1600 may be coupled to either the front or rear of the reciprocating rotating unit 1500, and one or more of the displacement generating unit 1330 and the driving unit 1200 may be disposed at the other end of the front or rear of the reciprocating rotating unit 1500. Therefore, the connecting unit 1600 may be prevented from interfering with the driving unit 1200.
[0446] The connecting part 1600 may be provided to reciprocate in the width direction of the inner case 200 and rotate the plurality of reciprocating rotating parts 1500 .
[0447] The driving unit 1200 may include a motor 1210 that rotates a rotating shaft 1210, a power shaft 1240 that rotates as the rotating shaft 1210 rotates, and a transmission unit 1230 that connects the power shaft 1240 and the rotating shaft 1210 and transmits the rotational force of the rotating shaft 1210 to the power shaft 1240.
[0448] The motor 1210 may be fixed to an upper portion of the inner case 200 and configured to rotate the rotating shaft 1220. However, the rotating shaft 1220 is configured to rotate at a speed much faster than an appropriate period for reciprocating rotation of the power transmission unit 1400 from the motor 1210. In consideration of this, if the RPM of the rotating shaft is reduced, the output of the motor 1210 may not be transmitted to the power transmission unit 1400.
[0449] To solve this problem, the transmission unit 1230 may be configured to transmit the output of the rotary shaft 1220 to the power transmission unit 1400 as is, but at a reduced RPM of the rotary shaft 1220 before transmission.
[0450] The transmission part 1230 is connected to the rotary shaft 1220 to rotate, and has a larger diameter than the rotary shaft 1220 so that the transmission part 1230 can transmit the torque of the rotary shaft 1220 even though it rotates slower than the RPM of the rotary shaft 1220.
[0451] The power shaft 1240 may be provided to rotate by the transmission unit 1230 , and is provided separately from the rotation shaft 1230 and configured to directly transmit power to the power transmission unit 1400 .
[0452] The reciprocating rotation unit 1500 is coupled to the power transmission unit 1400 and may be rotatable together with the power transmission unit 1400 .
[0453] The reciprocating rotation part 1500 may include a reciprocating lever 1510 coupled to an upper part of the power transmission part 1400 to rotate the power transmission part 1400 .
[0454] The reciprocating lever 1510 may be provided in the form of a rib or a rod whose rotation center is connected to the support shaft 1410 .
[0455] The reciprocating lever 1510 may be coupled to each of the upper ends of the plurality of power transmission units 1400, and some of the reciprocating levers 1510 may be connected to the transmission unit 1230 and configured to receive the power of the motor 1210.
[0456] The reciprocating lever 1510 may be configured to rotate reciprocally at a certain angle when the transmission unit 1230 rotates by the motor 1210. The power transmission unit 1400 may be coupled to the rotation center of the reciprocating lever 1510 and configured to be rotatable together with the reciprocating lever 1510.
[0457] The multiple reciprocating levers 1510 may be arranged connected by a connecting portion 1600 .
[0458] The connecting portion 1600 may be provided to connect one end of a plurality of reciprocating levers 1510 .
[0459] As a result, when any one of the reciprocating levers 1510 rotates, the connecting portion 1600 moves, allowing the reciprocating levers 1510 to rotate simultaneously.
[0460] The power transmission unit 1400 and the reciprocating lever 1510 may be supported by the support unit 1800. The motor 1210 and the transmission unit 1230 may also be supported by the support unit 1800.
[0461] FIG. 19 shows the moving hanger 1000 of the present invention separated from the inner case 200.
[0462] The power transmission part 1400 may extend from the top to the bottom of the inner case, and the hook part 1700 may be coupled to the bottom of the power transmission part 1400 .
[0463] The reciprocating rotation unit 1500 is coupled to each of the power transmission units 1400 and is coupled to the upper part of the power transmission unit 1400 so that it can be easily connected to the driving unit 1200 .
[0464] The power transmission unit 1400 and the reciprocating rotation unit 1500 are provided in plurality and are arranged at a predetermined distance apart along the width direction of the inner case.
[0465] The connecting unit 1600 is provided to connect the plurality of power transmission units 1400 or the plurality of reciprocating rotation units 1500 to each other, so that the connecting unit 1600 can rotate the plurality of power transmission units 1400 or the plurality of reciprocating rotation units 1500 simultaneously.
[0466] The power transmission part 1400 may include a support shaft 1410 that penetrates the upper part of the inner case 200 and is coupled to the reciprocating lever 1510 .
[0467] The support shaft 1410 may pass through the support part 1800 and be exposed at the top of the support part 1800 or the top of the inner case 200 .
[0468] The power transmission part 1400 may include an auxiliary support part 1420 coupled to the support shaft 1410 and exposed to the receiving space. The auxiliary support part 1420 may be rod-shaped, and a hook part 1700 may be coupled and fixed to a lower part of the auxiliary support part 1420.
[0469] The auxiliary support part 1420 is fixed to the support shaft 1410 and can rotate together with the support shaft 1410. Thus, when the support shaft 1410 rotates due to the reciprocating lever 1510, the auxiliary support part 1420 connected to the support shaft 1410 also rotates, and the hook part 1700 can also rotate left and right.
[0470] The reciprocating lever 1510 may include a main lever 1511 that receives power directly from the driving unit 1200 and rotates reciprocally, and an auxiliary lever 1512 that receives power from the main lever 1511 via a connecting unit 1600.
[0471] The main lever 1511 may be provided singly and may be provided to directly receive power from the driving unit 1200 .
[0472] In the driving unit 1200 , the motor 1210 may include a vertical motor 1211 coupled to the support unit 1800 and a vertical rotation shaft 1221 rotated by the vertical motor 1211 .
[0473] The transmission unit 1230 may include a power pulley 1231 coupled to the vertical rotation shaft 1221 and rotating together with the vertical rotation shaft 1221, a transmission pulley 1232 coupled to the power shaft 1240 and rotating the power shaft 1240, and a belt 1233 connecting a portion of the outer circumferential surface of the power pulley 1231 and the transmission pulley 1232.
[0474] The transmission unit 1230 may further include a pulley support unit 1224 that rotatably supports the power shaft 1240 and the transmission pulley 1232. The pulley support unit 1224 supports the transmission pulley 1232 so that it is arranged next to the power pulley 1231, and may be seated on the support unit 1800.
[0475] The power shaft 1240 may be provided to transmit the power transmitted from the rotation shaft 1220 to one end of the main lever 1511 .
[0476] The displacement generating unit 1300 may be coupled to the power shaft 1240 to receive power. In addition, the displacement generating unit 1300 may be connected to the main lever 1511 to rotate the main lever 1511 reciprocally around the support shaft 410.
[0477] For example, the displacement generating unit 1300 may include an eccentric shaft that is eccentrically coupled to the power shaft 1240 and rotates at a constant radius around the rotation center of the power shaft 1240 .
[0478] The displacement generating unit 1300 may be connected to an end of the main lever 1511. The displacement generating unit 1300 may rotate by the power shaft 1240, and may cause the end of the main lever 1511 to reciprocate around the support shaft 410.
[0479] The connecting unit 1600 may include a link bar 1610 that connects one end of the main lever 1511 that is not connected to the power shaft 1240 or the displacement generating unit 1300 to one end of the auxiliary lever 1512.
[0480] The auxiliary lever 1512 may be rotatably connected to the remaining support shaft 1410 that is not connected to the main lever 1511, and may be configured to extend in one direction from the portion connected to the support shaft 1410 and be connected to the link bar 1610.
[0481] The link bar 1610 may be provided in the form of a straight frame connecting one end of the main lever 1511 and one end of the auxiliary lever 1512. In this case, one end of the main lever 1511 and one end of the auxiliary lever 1512 may be arranged side by side with respect to the width direction of the link bar 1610.
[0482] The link bar 1610 may be provided singly to rotate the main lever 1511 and the auxiliary lever 1512 simultaneously around the respective support shafts 1410 .
[0483] The inner case 200 may have a through-hole 230 on which a portion of the support part 1800 is placed and through which the power transmission part 1400 is exposed to the receiving space 220 .
[0484] The through-hole 230 may be formed in the upper surface 22 of the inner case 200 along the direction in which the power transmission part 1400 is disposed.
[0485] For example, the power transmission parts 1400 are arranged apart from each other along the width direction of the inner case 200, and the through holes 230 are arranged along the width direction of the inner case 200.
[0486] The clothing treatment device 1 of the present invention may further include a support frame 120 disposed outside the inner case 200 and supporting the cabinet 100 .
[0487] The support frame 120 may be disposed at positions corresponding to the corners of the cabinet 100 or the inner case 200, and may be made of a metal material that maintains the appearance of the clothing treatment device. Both ends of the support part 1800 are seated and supported by the support frame 120, thereby preventing unnecessary impact or load from being transmitted to the upper surface 220 of the inner case 200.
[0488] FIG. 20 shows how the moving hanger 1000 of the present invention operates.
[0489] Referring to FIG. 20( a ), the main lever 1511 may include a main body 15111 coupled to the support shaft 1410 and coupled to the connection bar 1610 .
[0490] The main body 15111 is coupled to the support shaft 1410 and includes a main center hole 15115 for rotating the support shaft 1410, and may be extended from the main center hole 15115 to both sides.
[0491] The main body 15111 may have a main receiving hole 15112 at one end for receiving power from the driving unit 1200, and a main transmitting hole 15113 at the other end to which the connection bar 1610 is seated and coupled.
[0492] The main body 15111 may further include a step portion 15114 extending from the center hole to the main receiving hole 15112 and forming a step. Due to the step portion 15114, one end of the main body 15111 or the main transmitting hole 15113 may be positioned further lower than the main center hole 15115.
[0493] Therefore, the power shaft 1240 or the eccentric shaft 1310 disposed above the main central hole 15115 can be extended from the transmission part 1230 with a sufficient length.
[0494] Meanwhile, the auxiliary lever 1512 may include an auxiliary body 15121 having an auxiliary central hole 15125 connected to the support shaft 1410 and an auxiliary transmission hole 15123 extending to one side from the auxiliary central hole 15125 and connected to the link bar 1610.
[0495] The auxiliary body 15121 may be configured to have a length shorter than that of the main body 15111 .
[0496] The distance from the main central hole 15115 to the main transmission hole 15113 may be set to be the same as the distance from the auxiliary central hole 15125 to the auxiliary transmission hole 15123 .
[0497] The link bar 1610 is seated on the upper part of the auxiliary transmission hole 15123 and the main transmission hole 15113, and can connect the auxiliary lever 1512 and the main lever 1511 to each other.
[0498] 20(b), the driver 1210 may be configured such that the power shaft 1240 is inserted into the main receiving hole 15112. This allows the power shaft 1240 to be directly rotated to rotate the main receiving hole 15112 left and right.
[0499] In other words, the rotation of the power shaft 1240 alone may not generate enough displacement to rotate the main receiving hole 15112 left and right with the main central hole 15115 as the reference.
[0500] To this end, the displacement generating unit 1300 may be coupled to the powered shaft 1240 and configured to generate a displacement greater than the radius of rotation of the powered shaft 1240 .
[0501] The displacement generating unit 1300 may be configured to convert the rotational motion of the power shaft 1240 at a fixed position into a displacement motion that reciprocates within a certain range. The displacement motion is transmitted to the reciprocating rotation unit 1500, allowing the power transmission unit 1400 to rotate reciprocally.
[0502] As described above, the displacement generating unit 1300 may include the eccentric shaft 1310 that extends from the power shaft 1240 and rotates along a locus along a certain radius.
[0503] The eccentric shaft 1310 may have a smaller diameter than the power shaft 1240 and may be coupled to or extended from the power shaft 1240 at a predetermined distance from the rotation center of the power shaft 1240 .
[0504] As a result, when the power shaft 1240 rotates, the eccentric shaft 1310 can rotate in a circle whose radius is the distance from the power shaft 1240 .
[0505] The diameter of the eccentric shaft 1310 may be set smaller than the diameter or width of the main receiving hole 15112 .
[0506] The eccentric shaft 1310 may be inserted into and supported by the main receiving hole 15112 .
[0507] However, the constant radius around which the eccentric shaft 1310 rotates may be set to be larger than the width or diameter of the main receiving hole 15112. As a result, when the eccentric shaft 1310 rotates, the main receiving hole 15112 is pushed by the eccentric shaft 1310 and can move left and right based on the main central hole 15115.
[0508] As a result, when the eccentric shaft 1310 rotates in a specific direction (x), the main receiving hole 15112 of the main body 1511 also rotates back and forth along a certain direction (y), and as a result, the central hole 15115 of the main body also rotates in the same direction as the main receiving hole 15112, and the main transmission hole 15113 can rotate back and forth in the direction opposite to the certain direction (z).
[0509] When the eccentric shaft 1310 rotates, the support shaft 1410 rotates reciprocally together with the main central hole 15115, allowing the power transmission unit 1400 to rotate reciprocally, and the main transmission hole 15113 also rotates reciprocally to move the link bar 1610 reciprocally, allowing the auxiliary lever 1521 to rotate reciprocally around the auxiliary central hole 15125 and the support shaft 1410. The power transmission unit 1400 coupled to the auxiliary lever 1521 can also rotate reciprocally.
[0510] The power transmission part 1400 may have a screw thread formed around the upper portion of the support shaft 1410 .
[0511] The main transmission hole 15113 and the auxiliary central hole 15125 can be directly coupled and fixed to the support shaft 1410 using threads or the like.
[0512] However, the power transmission part 1400 may further include a transmission coupling part 1415 that is coupled to the threads of the support shaft 1410 to fix the support shaft 1410 to the main transmission hole 15113 and the auxiliary central hole 15125 after the support shaft 1410 passes through the main transmission hole 15113 and the auxiliary central hole 15125.
[0513] Therefore, the support shaft 1410 and the reciprocating lever 1510 are coupled by the transmission coupling part 1415, so that the support shaft 1410 and the reciprocating lever 1510 can rotate simultaneously.
[0514] The following describes an embodiment in which the control unit 700 of the clothing processing device of the present invention executes any course based on the above configuration.
[0515] FIG. 21 shows the process of the laundry treatment device of the present invention performing a course of treating laundry.
[0516] The clothing treatment device of the present invention can be configured to have a maximum allowable power amount set as the maximum amount of power that can be used. The control unit 700 of the clothing treatment device can be configured to cut off the power supply when it detects that the clothing treatment device is consuming more than the allowable power amount.
[0517] The allowable power amount may be smaller than the power amount consumed when the first heater 841, the second heater 842, and the compressor 342 are simultaneously driven. As a result, the clothing treatment device of the present invention is configured so that the entire steam heater 840 and the compressor 342 cannot be driven simultaneously.
[0518] As a result, the clothing treatment device of the present invention is configured so that the first heater 841 and the second heater 842 cannot be driven simultaneously while the compressor 342 is in operation, and the compressor 342 cannot be driven while the first heater 841 and the second heater 842 are in operation simultaneously.
[0519] Therefore, the clothing treatment device of the present invention may be set so that it is not possible to simultaneously supply the maximum amount of steam possible while hot air is being supplied inside the inner case 200.
[0520] However, the allowable power amount may be greater than the power amount consumed when the first heater 841 and the second heater 842 are simultaneously driven. Furthermore, the allowable power amount may be greater than the power amount consumed when the first heater 841 and the compressor 342 are simultaneously driven. Furthermore, the allowable power amount may be greater than the power amount consumed when the second heater 842 and the compressor 342 are simultaneously driven.
[0521] As a result, the first heater 841 and the second heater 842 can be driven simultaneously, the first heater 841 and the compressor 342 can be driven simultaneously, and the second heater 842 and the compressor 342 can be driven simultaneously.
[0522] Therefore, when the compressor 342 is not operating, the clothing treatment device of the present invention can simultaneously operate the first heater 841 and the second heater 842 to supply the maximum amount of steam that can be supplied to the inside of the inner case.
[0523] In addition, the clothing treatment device of the present invention can simultaneously drive either the first heater 841 or the second heater 842 and the compressor 342 to supply the steam into the inner case 200 while simultaneously supplying hot air into the inner case 200, and can also simultaneously supply steam into the inner case 200 while supplying hot air.
[0524] The clothing treatment device of the present invention can initially drive the first heater 841 and the second heater 842 simultaneously to quickly heat the water inside the steam generator 810 and generate steam preferentially. After that, when steam is generated, the clothing treatment device of the present invention can drive only one of the first heater 841 and the second heater 842 to maintain the temperature of the water at, for example, the boiling point and continue generating steam.
[0525] However, in this case, after the steam is generated, the amount of steam injected may decrease compared to when the first heater 841 and the second heater 842 are driven simultaneously.
[0526] The clothing treatment device of the present invention can adjust the amount of steam supplied by driving only either the first heater 841 or the second heater 842. This allows only a small amount of steam to be supplied to materials that are sensitive to moisture and temperature, such as silk and cashmere, to perform a sufficient refreshing process.
[0527] In the clothing processing device of the present invention, when steam is supplied to the inside of the inner case, only one of the first heater 841 and the second heater 842 can be used, so that the amount of power required for supplying steam can be reduced.
[0528] In addition, the clothing treatment device of the present invention can quickly increase the temperature inside the inner case by simultaneously driving the compressor 342 when supplying steam. As a result, the clothing treatment device of the present invention can quickly complete the drying process to remove moisture from wet clothing, and the refreshing process to sterilize, deodorize, and remove wrinkles from clothing.
[0529] FIG. 21(a) shows one embodiment of a method for controlling a clothing processing device of the present invention.
[0530] When the refreshing course or standard course that performs the refreshing process is executed, the clothing treatment device of the present invention can execute a steam preparation step (A1) in which a steam heater is driven to heat water, and when the water is heated and steam is generated during the steam preparation step (A1), a steam injection step (A2) in which the steam is supplied to clothing.
[0531] Generally, the refreshing step is intended to supply moisture to dry clothes, so a large amount of steam needs to be sprayed onto the clothes.
[0532] Therefore, the clothing treatment device of the present invention can simultaneously drive the first heater 841 and the second heater 842 in the steam preparation step (A1) and the steam injection step (A2).
[0533] In the steam preparation step (A1) and the steam injection step (A2), the compressor 342 may not be driven in consideration of the allowable amount of power.
[0534] The laundry treatment device of the present invention performs a waiting step (A3) to provide time for the laundry to absorb moisture with the supplied steam.
[0535] After the standby step (A3) is performed for a certain period of time, the clothing treatment device of the present invention performs a cooling step (A4) to further lower the surface temperature of the clothing before starting the compressor and to operate only the blower fan, thereby preventing heat damage to the clothing.
[0536] When the internal temperature of the inner case 200 drops and the moisture content of the clothes becomes sufficient, the clothes treating device of the present invention performs a drying step (A5) by driving one or more of the compressor 342 and the blower fan 351.
[0537] The drying step (A5) dries the moisture contained in the clothes while performing refreshing processes such as deodorizing the clothes and removing wrinkles. The drying step (A5) lasts the longest time of all the steps performed so far.
[0538] Meanwhile, in the steam injection step (A2), the compressor cannot be driven and hot air cannot be supplied, so the temperature inside the inner case 200 and the temperature of the refrigerant flowing through the heat supply unit 400 are relatively low until the drying step (A5).
[0539] Therefore, in the above-described control method, only after the drying step (A5) has been continued for a relatively long time can the refreshing performance including complete drying, sterilization, deodorization, and wrinkle removal of the clothes be guaranteed.
[0540] FIG. 21(b) shows another embodiment of the method for controlling a clothing processing device of the present invention.
[0541] However, in the clothing treatment device of the present invention, as described above, the heater is divided into multiple sections, so that some of the heaters and the compressor can be driven simultaneously.
[0542] For example, since the steam heater 840 includes a first heater 841 and a second heater 842, it is possible to drive either the first heater 841 or the second heater 842 and the compressor at the same time. This allows the refreshing process to be performed in another way.
[0543] Therefore, the clothing treatment device of the present invention can quickly raise the temperature inside the inner case 200 before the drying stage by simultaneously driving the heater and compressor before the drying stage, and can more quickly ensure the temperature and time required for complete drying, sterilization, deodorization, and wrinkle removal of clothing.
[0544] As a result, the duration of the drying stage can be shortened compared to conventional methods. Furthermore, the duration of the drying stage can be set to be the longest in the refreshing stage. By shortening the duration of the drying stage, the duration of the entire refreshing stage can be significantly shortened. Furthermore, by shortening the driving time of the compressor, energy efficiency can be significantly improved.
[0545] When any course capable of refreshing or maintaining clothes is executed, the clothing treatment device of the present invention can execute a steam preparation step (B1) in which all of the steam heaters 840 are driven to supply steam to the clothes.
[0546] In the steam preparation step (B1), the control unit 700 can drive all the heaters of the steam heater 840 since the refresh process time can be shortened as the steam is generated more quickly.
[0547] That is, in the steam preparation step (B1), the control unit 700 can heat water using the maximum power of the steam heater 840.
[0548] When the steam heater 840 is composed of the first heater 841 and the second heater 842, the first heater 841 and the second heater 842 can be driven simultaneously to heat water.
[0549] In the steam preparation step (B1), when the detection device 860 detects that steam is generated inside the steam case 810, the clothing treatment device of the present invention can perform a preheating step (B2) in which only a portion of the steam heater 840 is driven.
[0550] That is, after steam is generated in the steam case 810, even if only one of the first heater 841 and the second heater 842 is driven, the steam can be continuously generated and supplied to the inner case 200.
[0551] In the pre-heating step (B2), the control unit 700 can supply heat to the inside of the inner case 200 by driving only one of the first heater 841 and the second heater 842.
[0552] As a result, the clothing treatment device of the present invention can increase the temperature inside the inner case 200 and the moisture content of the clothing by using the steam from the preheating step (B2). Also, since only a portion of the steam heater 840 is used in the preheating step (B2), extra power can be secured.
[0553] In the preheating step (B2), the laundry treatment device of the present invention can drive one or more of the compressor 342 and the blower fan 351. As a result, hot air can also be supplied into the inner case 200.
[0554] As a result, in at least a part of the preheating step (B2), the compressor 342, the blower fan 351, and a part of the steam heater 840 can be driven simultaneously in an overlapping manner.
[0555] In the preheating step (B2), one of the first heater 841 and the second heater 842 and the compressor 342 can be driven simultaneously. Steam and hot air can be supplied into the inner case 200 at the same time.
[0556] When either the first heater 841 or the second heater 842 and the compressor 342 are driven simultaneously, the temperature inside the inner case 200 can be increased from the initial stage of the refreshing process, and hotter air is introduced into the evaporator 341. As a result, the heat exchange performance of the evaporator 341 is strengthened, and the condenser 343 can be heated to a higher temperature. Therefore, hotter air is supplied into the inner case 200, and the inside of the inner case 200 can reach the optimum temperature or the minimum temperature required for the refreshing process more quickly. Therefore, the execution time of the subsequent refreshing process can be significantly reduced.
[0557] In addition, the coefficient of performance (COP) of the entire heat supply unit 340 can be increased.
[0558] The preheating step (B2) may include at least one of a section in which either one of the first heater 841 and the second heater 842 and the compressor 342 are simultaneously driven, and a section in which only the compressor 342 is driven.
[0559] For example, in the preheating step (B2), there may be a section in which the steam heater 840 and the compressor 342 are driven simultaneously, as well as a section in which only the compressor 342 is driven.
[0560] However, it is preferable that the section in which only the compressor 342 is driven is disposed after the section in which the steam heater 840 and the compressor 342 are driven.
[0561] This is because it is more advantageous to drive the heat supply unit 340 if air with high heat capacity is supplied to the evaporator 341 before driving the compressor 342. That is, when the steam is supplied to the inner case 200 through the steam heater 840, not only the temperature inside the inner case 200 but also the absolute humidity increases, and the air with high heat capacity may come into contact with the evaporator 341.
[0562] Specifically, the preheating step (B2) may include a first section in which either the first heater 841 or the second heater 842 and the compressor 342 are driven, and a second section in which the driving of the first heater 841 and the second heater 842 is stopped and only the compressor 342 is driven.
[0563] By supplying hot air and steam to the inner case 200 through the first section, the temperature inside the inner case 200 and the heat amount of the air flowing into the circulation duct 320 can be increased.
[0564] Through the second section, hot air is supplied into the inner case 200 in earnest, thereby satisfying the minimum temperature conditions required for refreshing the clothes, such as deodorizing, removing wrinkles, and sterilizing.
[0565] In the preheating section (B2), the first heater 841 can be driven. As a result, a larger amount of steam is supplied into the inner case 200 than when the first heater 841 is driven, and the temperature inside the inner case 200 and the heat amount of the air flowing into the circulation duct 320 can be further increased.
[0566] Alternatively, the second heater 842 may be driven in the preheating section B2.
[0567] Therefore, the preheating section (B2) gradually increases the temperature inside the inner case 200 and can stably maintain the increased temperature for a longer period of time, thereby ensuring the time required for sterilization and the like.
[0568] Furthermore, it is possible to prevent the clothes from being deformed due to high humidity.
[0569] Meanwhile, the clothing treatment device of the present invention can be configured to stop the operation of the steam heater 840 if the temperature inside the inner case 200 rises suddenly in the preheating section (B2) or if the temperature of the refrigerant discharged from the compressor 342 exceeds the limit temperature.
[0570] Furthermore, the clothing treatment device of the present invention may be configured to operate either the first heater 841 or the second heater 842 so that it alternates between ON and OFF during the preheating section (B2). That is, when the temperature of the refrigerant approaches or exceeds a threshold temperature, the control unit 700 may alternately stop the operation of the steam heater 840, and resume the operation of the steam heater 840 when the temperature of the refrigerant reaches a safe temperature lower than the threshold temperature. Furthermore, when the temperature inside the inner case 200 approaches or exceeds a target temperature, the control unit 700 may alternately stop the operation of the steam heater 840, and resume the operation of the steam heater 840 when the internal temperature reaches a cooling temperature lower than the target temperature.
[0571] On the other hand, even if the steam heater 840 is driven intermittently, the preheating section (B2) aims to quickly increase the temperature inside the inner case 200, so the driving time of the first heater 841 and the second heater 842 can be set longer than the stopping time of the first heater 841 and the second heater 842.
[0572] The preheating section B2 may be performed for a predetermined time and may be terminated when the temperature inside the inner case or the temperature of the refrigerant is maintained at a predetermined temperature for a predetermined time or more.
[0573] When the preheating section (B2) is completed, the clothing treatment device of the present invention can perform a steam injection step (B3) to fully supply steam into the inner case 200. In the steam injection step (B3), the first heater 841 and the second heater 842 are simultaneously driven, so that a large amount of steam can be supplied to the inner case 200.
[0574] Since the clothes hung in the inner case 200 are heated to a certain degree in the preheating step B2 before the steam injection step B3 is performed, the moisture content of the entire clothes can be significantly increased.
[0575] The steam injection step (B3) can be performed in a shorter time than the steam injection step (A2) without the preheating step (B2) because a certain amount of steam has already been supplied in the preheating step (B2), and therefore the amount of steam to be additionally supplied is set to be small.
[0576] The steam injection step (B3) can be terminated after a guaranteed time has elapsed to ensure that the clothes are sufficiently moistened.
[0577] After the steam injection step (B3) is completed, the drying step (B6) is performed to dry the clothes with hot air. However, after the steam injection step (B3) is completed, a waiting step (B4) can be additionally performed to wait for a predetermined time to ensure that the steam injected into the inner case 200 has time to penetrate the entire clothes.
[0578] The standby step (B4) corresponds to a state in which the steam heater 840 and the compressor 342 are not driven.
[0579] The standby step (B4) prevents the steam injected into the inner case from evaporating immediately before it is absorbed into the clothes, and also prevents damage to the clothes caused by a sudden increase in the surface temperature of the clothes due to the supply of additional hot air when the surface temperature of the clothes has already increased due to the steam.
[0580] The drying step B6 is a step of driving the compressor 342 to supply full-scale hot air to the inner case 200. Therefore, if hot air is supplied immediately before the temperature inside the inner case 200 drops below a safe temperature, the temperature inside the inner case 200 may rise above the critical temperature, which may damage the clothes.
[0581] Therefore, before the drying step (B6), a cooling step (B5) can be performed in which the blower fan 352 is driven. In the cooling step (B5), the control unit 700 can drive the blower fan 352 but can cut off the compressor 342 and the steam heater 340.
[0582] In the cooling step B5, the air inside the inner case 200 is circulated along the circulation duct 320 and cooled.
[0583] When the temperature inside the inner case 200 drops below a safe temperature or the cooling step B5 has been performed for a predetermined time, the cooling step B5 can be terminated.
[0584] The laundry treatment device of the present invention can perform a drying step (B6) of supplying hot air to the laundry. The drying step (B6) can be performed until the moisture content of the laundry drops below a predetermined level.
[0585] The control unit 700 can recognize that the moisture content has decreased to a predetermined level or lower by detecting the temperature inside the inner case 200 or the temperature of the refrigerant.
[0586] For example, if the moisture content of the clothes is high, even if the drying step (B6) is performed, the temperature of the clothes re-entering the circulation duct 320 due to the heat of evaporation may not increase, or may not increase rapidly.
[0587] However, if the clothes are almost dry and the moisture content is below a certain level, the heat of vaporization is low, so the temperature flowing into the circulation duct 320 may rise rapidly and eventually correspond to the temperature of the hot air.
[0588] This is because the temperature of the refrigerant can also fluctuate in a similar pattern to the temperature of the refrigerant entering the circulation duct 320 .
[0589] The control unit 700 may terminate the drying step (B6) when it detects that the moisture content of the clothes is decreasing and the clothes are sufficiently dried and the minimum time required for refreshing has elapsed.
[0590] Alternatively, the control unit 700 may terminate the drying step (B6) when the time during which the clothes are exposed to a temperature equal to or higher than the minimum drying temperature condition reaches a minimum time.
[0591] As a result, the clothing treatment device of the present invention can significantly shorten the duration of the drying step (B6) by further placing a preheating step (B2) before the drying step (B6), thereby increasing the overall time for the temperature inside the inner case 200 to reach or exceed the minimum condition temperature.
[0592] Meanwhile, the clothing treatment device of the present invention can continuously maintain the compressor 342 in a stopped state after it is driven in the preheating section (B2) and then stopped until before the drying step (B6) is performed.
[0593] FIG. 22 shows an embodiment of the drying course of the clothes treating device of the present invention.
[0594] When the drying course is carried out, the drying course may be carried out in the order of a first stage or heating stage, a second stage or constant rate stage, a third stage or decreasing rate stage, and a fourth stage or cooling stage.
[0595] Wet clothes or clothes with a moisture content higher than the moisture content removal rate can be hung inside the inner case 200.
[0596] 22(a), when the first stage is performed, one or more of the compressor 342 and the blower fan 352 can be driven. This heats the refrigerant and also the air inside the inner case 200, and the air becomes hotter due to the blower fan 352, allowing it to circulate through the inner case 200 and the circulation duct 320. During this process, moisture in the clothes can begin to evaporate.
[0597] 22(b), when the first stage is continued for a certain period of time, high-temperature air (hot air) capable of evaporating the moisture in the clothes is supplied into the inner case 200. During this process, the moisture contained in the clothes also evaporates more and more, and more heat of vaporization can be absorbed from the hot air. As a result, even though hot air is being supplied into the inner case 200, the temperature increase rate inside the inner case 200 decreases below a reference value, or a constant rate stage is performed in which the temperature inside the inner case 200 is maintained.
[0598] For example, the reference value can be set as a rate of increase of 1 degree per minute or 0.3 degrees per minute, but this is only one embodiment, and the reference value can be set as any rate of temperature increase over time as long as it can distinguish between the first and second stages.
[0599] In the second step, the control unit 700 may drive the moving hanger 1000. The hanger unit 1900 hung on the moving hanger 1000 may reciprocate or vibrate, thereby achieving the removal physical force condition in the constant rate step.
[0600] In the second stage, the moisture content of the clothes gradually decreases from 100 percent to reach the moisture removal rate. However, in the second stage, the moisture in the clothes continuously evaporates and absorbs the heat of vaporization from the air inside the inner case 200, so the temperature inside the inner case 200 is lower than the set temperature.
[0601] The set temperature may be defined as the temperature at which wrinkle removal of the garment begins, for example, the set temperature may correspond to 37 degrees Celsius.
[0602] 22(c), if the second stage is performed for a certain period of time, the moisture content of the clothes may fall below the moisture removal rate. From this point on, the amount of moisture evaporating from the clothes decreases rapidly, and the heat of vaporization absorbed from the air inside the inner case 200 also decreases. As a result, the third stage may be performed, in which the rate of temperature increase inside the inner case 200 exceeds a reference value.
[0603] When the third stage is started, the temperature inside the inner case 200 may reach or exceed the set temperature. Specifically, in the third stage, the temperature inside the inner case 200 may reach or exceed a drying temperature that is higher than the set temperature.
[0604] For example, the drying temperature can be set to 50 degrees or higher.
[0605] Furthermore, when the third stage is performed, the clothes are almost completely dried, and the moisture content of the clothes drops to less than 5%, which is much lower than the moisture content to be removed.
[0606] If the third step is performed for a predetermined time or more, the control unit 700 may terminate the drying course. The control unit 700 may perform a fourth step of stopping the operation of the compressor 342 and driving the blower fan 352 until the temperature inside the inner case 200 drops below a safe temperature that is lower than the set temperature.
[0607] The safe temperature may correspond to room temperature, for example, the safe temperature may be set to 25 degrees.
[0608] Referring to FIG. 22(d), the control unit 700 may additionally perform a removing step to remove wrinkles or creases from the clothes.
[0609] The steam heater 840 can be driven to supply steam into the inner case 200. As a result, the moisture content of the clothes inside the inner case 200 can be increased again to the moisture removal content.
[0610] In addition, the control unit 700 can drive the moving hanger 1000 to apply a removing physical force to the clothes.
[0611] As a result, in the removing step, the control unit 700 can simultaneously drive the steam heater 840 and the moving hanger 1000 to remove wrinkles and creases from the clothes.
[0612] Since the removing step is additionally performed after the fourth step, the temperature inside the inner case 200 may become higher than the set temperature. Therefore, during the removing step, the control unit 700 may stop driving the compressor.
[0613] After the removal step is performed, a cooling step may be performed to lower the temperature inside the inner case 200 to a safe temperature lower than the set temperature. In the cooling step, the blower fan 352 may be driven, and the steam heater 840 and the compressor 342 may be shut off.
[0614] Meanwhile, in either the removing step or the cooling step, the compressor 342 may be re-driven to dry the moisture supplied from the steam heater 840 .
[0615] As a result, the laundry treatment device of the present invention can remove wrinkles and creases from the laundry by additionally performing the removing step after completing all the drying steps up to the fourth step.
[0616] FIG. 23 shows the progress of the drying course of FIG.
[0617] Referring to FIGS. 23(a) and 23(b), when the drying course is executed, the compressor 342 starts to operate, and the operation of the compressor 342 can be maintained without being stopped until the end of the drying course.
[0618] When the compressor 342 is driven, the blower fan 352 can also be driven at the same time.
[0619] As a result, hot air can be continuously supplied into the inner case 200 during the drying course.
[0620] When the compressor 342 starts to operate, the first stage may be performed in which the temperature inside the inner case 200 gradually increases until the temperature of the refrigerant increases.
[0621] Then, when the heating of the refrigerant is completed, hot air is supplied into the inner case 200, and the moisture contained in the clothes is evaporated, so that the temperature rise rate inside the inner case 200 becomes lower than the reference value, and a second stage can be performed.
[0622] In the second stage, the set temperature may not be reached due to the heat of vaporization of the clothing.
[0623] Thereafter, when the moisture content of the clothes reaches less than 5%, a fourth step may be executed in which the temperature inside the inner case 200 exceeds the set temperature and continuously rises to the drying temperature or above.
[0624] Since the compressor 342 is always kept running, the steam heater 842 is shut off, reducing the overall power consumption of the laundry treatment device. Also, in the dry course, since the moisture content of the laundry is high, steam may not be supplied to the laundry.
[0625] The moving hanger 1000 can be driven to shake the clothes, thereby shaking the clothes to remove moisture and evenly expose the entire clothes to hot air.
[0626] Alternatively, in the first stage, in the section where the moisture content of the clothes is higher than the moisture content to be removed, the weight of the clothes is heavy, so the driving of the moving hanger 1000 may be stopped.
[0627] As a result, if the wrinkle removal step is not performed, there may be no section that satisfies all of the removal conditions up to the fourth step in the embodiment of the present invention shown in Figures 22 and 23. Therefore, in this embodiment of the drying course control method, clothes can be dried quickly, but wrinkles and creases in the clothes may not be removed.
[0628] FIG. 24 shows another embodiment of the drying course carried out by the clothes treating device of the present invention.
[0629] The clothing treatment device of the present invention can supply steam into the inner case 200 in the initial section when the drying course is performed.
[0630] Even if steam is supplied to clothes with a high moisture content, the moisture content of the clothes does not increase significantly or remains almost the same, so no additional energy is required to remove moisture with the steam. Also, since the steam does not lose heat due to evaporation or the like, the temperature inside the inner case 200 can be rapidly increased.
[0631] As a result, the clothes treatment device of the present invention can supply steam at the beginning of the drying cycle to raise the temperature inside the inner case above the set temperature, thereby achieving the removal condition, and thus wrinkles and creases in the clothes can be automatically removed.
[0632] Referring to FIG. 24(a), when the drying course is executed, the clothing treatment device of the present invention can execute a first step of driving the compressor 342 and the blower fan 352 to supply heated air inside the inner case 200.
[0633] In the first step, the control unit 700 may drive the steam heater 840 .
[0634] Specifically, the control unit 700 can generate steam by driving either the first heater 841 or the second heater 842 while the compressor 342 is being driven.
[0635] That is, the control unit 700 may drive the compressor 342 first, and then drive either the first heater 841 or the second heater 842 simultaneously with the compressor 342 .
[0636] In addition, the control unit 700 may simultaneously drive the first heater 841 and the second heater 842 to first heat the water contained in the steam case 381, and then drive the compressor 342. Thereafter, the control unit 700 may drive either the first heater 841 or the second heater 842 to supply steam.
[0637] That is, the control unit 700 can drive the first heater 841 and the second heater 842 first, and then drive the compressor 342 later.
[0638] However, even in this case, the operation of either the first heater 841 or the second heater 842 is stopped before the compressor 342 starts to operate, so that only one of the first heater 841 or the second heater 842 is operated while the compressor 342 is operating.
[0639] Therefore, it can be said that either the first heater 841 or the second heater 842 is driven while the compressor 342 is driven first.
[0640] The control unit 700 may simultaneously drive either the first heater 841 or the second heater 842 and the compressor 342 in at least a portion of the first stage to simultaneously supply hot air and steam into the inner case 200. As a result, the temperature inside the inner case 200 may rise from the first stage to a set temperature or higher.
[0641] The control unit 700 can drive either the first heater 841 or the second heater 842 and the compressor 342 simultaneously from the start of the first stage, and can drive either the first heater 841 or the second heater 842 and the compressor 342 simultaneously after a certain time has elapsed from the start of the first stage.
[0642] This allows the first heater 841 and the second heater 842 to be driven simultaneously at the beginning of the first stage, and the compressor 342 to be shut off to allow time for the water to boil first, or even if the first heater 841 and the second heater 842 are not driven simultaneously at the beginning of the first stage, it is possible to prevent steam from being supplied from the early stage when the moisture content of the clothes is very high.
[0643] In the first stage, the steam heater 840 is driven so that the internal temperature of the inner case 200 can rise to a limit temperature that is higher than a set temperature.
[0644] The limit temperature can be set as a temperature that ensures that the internal temperature of the inner case 200 will not drop below the set temperature even if steam is not supplied and moisture contained in the clothes evaporates.
[0645] The limit temperature may be set as a specific temperature, or may be defined as a certain percentage (based on 0 degrees Celsius) of the initial temperature or a certain temperature increase.
[0646] For example, the limit temperature may correspond to 45 degrees Celsius, or to a temperature increased by 100% or 30 degrees relative to the initial temperature.
[0647] Referring to FIG. 24(b), when the first stage is completed and the second stage is entered, the moisture content of the clothes can reach the moisture removal content.
[0648] In addition, since steam and hot air are supplied simultaneously during the first stage, the clothes can reach the moisture removal rate during the first stage.
[0649] As a result, the clothes can be in a moisture removal state during a specific section spanning the first and second stages.
[0650] In the initial section of the second stage, steam can also be supplied into the inner case 200. This prevents the internal temperature of the inner case 200 from dropping below the set temperature due to the heat of vaporization.
[0651] Also, the control unit 700 can drive the moving hanger 1000 in the second stage, thereby applying a removing physical force to the clothes.
[0652] Of course, the control unit 700 can also drive the moving hanger 1000 from the first stage.
[0653] As a result, all the wrinkle removal conditions can be met in the second step.
[0654] Referring to FIG. 24(c), when the moisture content of the clothes is reduced below the moisture content removal level after the second step is performed, a third step can be performed.
[0655] However, since all wrinkles have been removed in the second stage, the third stage can be carried out with the garment free of wrinkles and creases.
[0656] In the third stage, since the moisture content of the clothes is low, the temperature inside the inner case 200 can rise above the drying temperature.
[0657] In the third stage, the first heater 841 and the second heater 842 may be completely turned off, thereby eliminating the unnecessary process of increasing the moisture content of the dried clothes again and preventing the internal temperature of the inner case 200 from rising excessively.
[0658] Referring to FIG. 24(d), when the internal temperature of the inner case 200 rises above a drying temperature that can ensure the drying of clothes, or when the drying time has elapsed at a temperature above the drying temperature, the control unit 700 can execute the aforementioned fourth step as is.
[0659] As a result, the laundry treatment device of the present invention can omit the additional wrinkle removal step after the first to fourth steps are performed to dry the laundry.
[0660] The clothes treating device of the present invention can be considered to include a wrinkle removal step within the drying course or to perform the wrinkle removal step automatically.
[0661] Furthermore, the clothing treatment device of the present invention can automatically remove wrinkles and creases from clothing while the drying course is being carried out.
[0662] That is, the clothing treatment device of the present invention can omit the process of supplying additional steam and re-drying the clothing after the moisture content of the clothing has dropped below 5%. The clothing treatment device of the present invention can also omit the process of stopping and restarting the compressor 342 to drive both the first heater 841 and the second heater 842 until the end of the drying cycle. The clothing treatment device of the present invention can also omit the inefficient process of increasing the moisture content of the clothing again when the moisture content is below the moisture removal level.
[0663] In addition, the clothing treatment device of the present invention can automatically remove wrinkles and creases from clothing during the drying course, preventing delays in drying or reduced drying efficiency due to the removal of wrinkles and creases from clothing.
[0664] Therefore, the clothing treatment device of the present invention can eliminate the need for a user to take additional measures to remove wrinkles or creases from clothing.
[0665] FIG. 25 shows the controlled state of the clothing processing device when the control method of FIG. 24 is executed.
[0666] In the first stage, the clothing treatment device of the present invention can drive either the first heater 841 or the second heater 842 simultaneously with the compressor 342 while the compressor 342 is running. This allows the internal temperature of the inner case 200 to be raised more quickly and to a higher level. As a result, even if the moisture content of the clothing is very high and has not yet reached the moisture removal content, the internal temperature of the inner case 200 can be raised to a set temperature or higher from the first stage.
[0667] On the other hand, in the clothing treatment device of the present invention, the temperature inside the inner case 200 rises further above the set temperature and up to the limit temperature due to the simultaneous operation of the steam heater 840 and the compressor 342, thereby achieving the effect of setting the execution time of the first stage longer.
[0668] Furthermore, by completing the first stage at a high temperature, there is also the effect of shortening at least one of the second and third stages.
[0669] For example, the first stage normally ends at the first time (t1) when the compressor 342 starts to operate and its operating rpm reaches the maximum rpm. However, in the clothing treatment device of the present invention, the temperature rise rate inside the inner case 200 is equal to or greater than the reference value from the first time (t1) until the third time (t3), so the first stage can be considered to be performed until the third time (t3).
[0670] Furthermore, in the clothing treatment device of the present invention, the rate of temperature increase inside the inner case 200 starts to become smaller than the reference value after the third time (t3).
[0671] Therefore, in the laundry treatment device of the present invention, the second stage can be started from the third time (t3).
[0672] Furthermore, since the temperature rise rate again exceeds the reference value from the seventh time (t7), the third stage can be considered to start from the seventh time, and since the temperature inside the inner case 200 exceeds the drying temperature from the eighth time, the third stage can be considered to be performed from the seventh time (t7) to the eighth time (t8).
[0673] The fourth step may be performed from the eighth time to the ninth time when the compressor 342 stops operating.
[0674] In a drying course embodiment in which steam is not supplied to the inside of inner case 200, the decreasing rate stage is normally continued even after the ninth hour, but in a drying course embodiment in which steam and hot air are supplied simultaneously at the beginning, the temperature inside inner case 200 is maintained higher than the set temperature, so the drying course can be completed at the eighth hour. In other words, the embodiment of Fig. 24 can significantly reduce the execution time of the drying course compared to the embodiment of Fig. 22.
[0675] Referring to Figures 25(a) and 25(b), the control unit 700 can maintain the operation of the compressor 342 from the initial time (t0) when the compressor starts to be operated until the ninth time (t9) when the drying course ends.
[0676] The control unit 700 may drive the compressor 342 from an initial time (t0) and maintain the drive until a ninth time (t9) when the drying course ends.
[0677] The control unit 700 can simultaneously drive the compressor 342 and the blower fan 352 from the first stage to the third stage, and can drive the blower fan 352 but not the compressor 342 in the fourth stage.
[0678] Referring to FIG. 25( c ), the control unit 700 may drive the steam heater 840 before driving the compressor 342 .
[0679] The control unit 700 can drive the entire steam heater 840 at maximum power earlier than the initial time (t0) to quickly heat the water contained in the steam case 810. For example, before driving the compressor 342, the control unit 700 can simultaneously drive the first heater 841 and the second heater 842 to generate steam as quickly as possible.
[0680] When the first heater 841 and the second heater 842 are simultaneously driven to generate steam, the control unit 700 can drive only one of the first heater 841 and the second heater 842.
[0681] The control unit 700 can start driving the compressor 342 when either the first heater 841 or the second heater 842 is driven.
[0682] Alternatively, the control unit 700 can drive either the first heater 841 or the second heater 842 after the compressor 342 is driven.
[0683] Alternatively, the control unit 700 can drive the first heater 841 and the second heater 842 simultaneously before the initial time (t0) to heat the water to a certain extent, and when the initial time (t0) is reached, drive either the first heater 841 or the second heater 842 to further heat the water and drive the compressor 342.
[0684] Alternatively, the control unit 700 may first drive the compressor 342 at an initial time (t0), and then drive either the first heater 841 or the second heater 842 after the initial time (t0) to heat water. Therefore, while the compressor 342 is being driven, a portion of the steam heater 840 is driven to heat water, and steam is generated only when the first time (t1) is reached, and steam can be supplied into the inner case 200 from the initial time (t0).
[0685] In either case, once the compressor 342 starts to operate, the operation of the compressor 342 is not stopped until the third stage is completed, and hot air is supplied to the inside of the inner case 200 first, followed by steam.
[0686] As a result, the control unit 700 can drive the steam heater 840 from the first stage to supply steam into the inner case 200.
[0687] The control unit 700 can maintain the operation of the steam heater 840 until the temperature inside the inner case 200 rises above a set temperature. In other words, the control unit 700 can maintain the operation of the first heater 841 or the second heater 842.
[0688] In addition, the control unit 700 may maintain the operation of the steam heater 840 even after the temperature inside the inner case 200 rises above a set temperature. For example, the control unit 700 may maintain the operation of the currently operating heater, either the first heater 841 or the second heater 842, until the temperature inside the inner case 200 rises to a limit temperature that is higher than the set temperature.
[0689] This is because even if the temperature inside the inner case 200 is above the set temperature, if the operation of the steam heater 840 is stopped, moisture will evaporate from the clothes inside the inner case 200 and absorb the heat of vaporization, which may cause the temperature inside the inner case 200 to drop below the set temperature again.
[0690] Therefore, even if the temperature inside the inner case 200 rises above the set temperature, the control unit 700 can maintain the operation of the first heater 841 or the second heater 842 until the temperature inside the inner case 200 enters the second stage where the rate of rise of the temperature inside the inner case 200 becomes below the reference value.
[0691] As a result, the clothing treatment device of the present invention can maintain the temperature inside the inner case 200 at or above the set temperature during at least part of the first and second stages, thereby meeting the conditions for removing wrinkles and creases from clothing.
[0692] The control unit 700 may stop driving the first heater 841 or the second heater 842 when the second stage is entered or the temperature inside the inner case 200 reaches a limit temperature. That is, the control unit 700 may stop supplying steam to the inner case 200 when the second stage is entered or the temperature inside the inner case 200 reaches a limit temperature. This may prevent the moisture content of the clothes from increasing or decreasing unnecessarily.
[0693] Of course, the control unit 700 can continuously supply steam by maintaining the operation of the first heater 841 or the second heater 842 until at least a part of the second stage, thereby completely preventing the temperature inside the inner case 200 from dropping below the set temperature.
[0694] The moisture content of the clothes starts to decrease from the first stage as the clothes start to dry from the first stage.
[0695] Even if the clothes hung in the inner case 200 are initially completely wet and have a moisture content of 100%, the moisture content of the clothes can reach the moisture removal level from the second time (t2) before the third time when the second stage begins. That is, the moisture content of the clothes can drop to 45% from the first stage.
[0696] Furthermore, from the second time (t2) to the sixth time (t6), which corresponds to the second stage, or from the fifth time (t5), which is earlier than the sixth time, the moisture content of the clothing corresponds to 45% to 5%, which satisfies the condition for moisture removal.
[0697] Furthermore, there is a possibility that deviation from the moisture content removal rate occurs before the sixth hour, which is before the seventh hour when the third stage is carried out.
[0698] To summarize, in the clothing treatment device of the present invention, between the second and sixth hours, which correspond to the first and second stages, the temperature inside the inner case 200 is higher than the set temperature and the clothing is placed in a moisture content removal state.
[0699] Therefore, in the clothing treatment device of the present invention, the control unit 700 can drive the moving hanger 1000 to transmit a removal physical force to the clothing during a portion of the first stage and a portion of the second stage between the second and sixth hours.
[0700] As a result, all of the removal conditions are satisfied in a part of the first stage section and a part of the second stage section between the second and sixth hours, and therefore these sections can be set as wrinkle removal sections (A).
[0701] In other words, the wrinkle removal section (A) can be defined as a section where the temperature where the clothes are placed is equal to or higher than the set temperature, the moisture content of the clothes corresponds to the removal moisture content, and all the removal conditions are met when only the removal physical force is applied.
[0702] The clothing processing device of the present invention can drive the moving hanger 1000 at least in the wrinkle removal section (A).
[0703] The control unit 700 may also intermittently drive the steam heater 840 driven in the wrinkle removal section A. That is, the control unit 700 may drive the first heater 841 or the second heater 842 by repeatedly turning them on and off. This prevents excessive steam from being supplied, prevents a sudden rise in the temperature inside the inner case 200, and maintains the reliability of the compressor 342.
[0704] In another aspect, the control unit 700 may intermittently drive the steam heater 840 when the temperature inside the inner case 200 corresponds to a limit temperature higher than a set temperature. The limit temperature may correspond to a temperature at which the temperature of the refrigerant input to the compressor 342 or the refrigerant discharged from the compressor 342 may reach a limit temperature that threatens the reliability of the compressor 342.
[0705] For example, the limit temperature corresponds to 90 degrees Celsius.
[0706] Therefore, the control unit 700 can drive the first heater 841 or the second heater 842 intermittently in a temperature range equal to or higher than the limit temperature.
[0707] In the wrinkle removal section (A), the control unit 700 may supply steam into the inner case 200, but may stop driving the steam heater 840 at a third time (t3) that is earlier than a sixth time (t6) at which the wrinkle removal section (A) ends. This prevents the humidity inside the inner case 200 from increasing unnecessarily and prevents energy from being wasted in the wrinkle removal section (A).
[0708] The wrinkle removal section (A) can be set between the second time and the sixth time, but may be set shorter than that as long as it includes the set time that is the minimum time required for wrinkle removal between the second time and the sixth time.
[0709] That is, during the set time in the wrinkle removal section (A), the control unit 700 can swing the moving hanger 1000 or drive the steam heater 840 to maintain the temperature above the set temperature. That is, steam is supplied into the inner case 200 until the set time has elapsed, and after the set time has elapsed, the drive of the steam heater 840 can be cut off even before the sixth hour.
[0710] For example, the set time corresponds to 15 minutes.
[0711] Referring to FIG. 25(d), the control unit 700 can drive the moving hanger 1000 for at least a set time in the wrinkle removal section (A).
[0712] If the moving hanger 1000 has not been driven before the wrinkle removal section (A), the control section 700 can drive the moving hanger 1000 for at least a set time in the wrinkle removal section (A).
[0713] Therefore, if the moving hanger 1000 is driven while the steam heater 840 is being driven, even if the steam heater stops driving, if the set time has not elapsed, the moving hanger 1000 can maintain the driving speed for a certain period of time until the set time has elapsed.
[0714] That is, even if the steam heater 840 is not driven for the set time, the temperature inside the inner case 200 can be maintained above the set temperature. However, if the moving hanger 1000 is not driven for the set time, the condition of the removal physical force cannot be met. For example, the steam heater 840 may be turned off at the third time (t3), but the moving hanger 1000 may continue to be driven until at least the sixth time (t6).
[0715] When the above-described control method is analyzed from the viewpoint of driving the moving hanger 1000 and the steam heater 840, it can be interpreted as follows.
[0716] The moving hanger 1000 may be driven to at least partially overlap with the section in which the steam heater 840 is driven.
[0717] The control unit 700 may drive the moving hanger 1000 in a section where the temperature inside the inner case 200 is at least equal to or higher than the set temperature.
[0718] In addition, the control unit 700 can drive the moving hanger 1000 while the first heater 841 or the second heater 842 is being driven.
[0719] Furthermore, if the control unit 700 has driven the moving hanger at a first frequency (1 rpm) before the wrinkle removal section (A), it can drive the moving hanger at a second frequency (2 rpm) faster than the first frequency during the wrinkle removal section (A).
[0720] If the moving hanger 1000 starts to operate before the steam heater 840 is operated, the control unit 700 can operate the moving hanger 1000 faster in the section where the steam heater 840 is operating.
[0721] If the moving hanger 1000 has not been driven before the steam heater 840 is driven, the control unit 700 can drive the moving hanger 1000 in at least a portion of the section in which the steam heater 840 is driven.
[0722] As a result, by applying a physical force equal to or greater than the removal physical force to the clothes in the wrinkle removal section (A), the removal condition is further satisfied, and wrinkles and creases in the clothes can be reliably removed.
[0723] The control unit 700 can stop driving the moving hanger 1000 after the wrinkle removal section (A) or drive the moving hanger 1000 at a third frequency (3 rpm) slower than the second frequency, thereby preventing overload of the moving hanger 1000 in the drying course and saving energy.
[0724] The first frequency may be set lower than the third frequency, thereby preventing the moving hanger 1000 from consuming excessive energy to shake heavy clothes with high moisture content, and minimizing vibrations generated in the entire clothes treating device.
[0725] When the control unit 700 drives the moving hanger 1000 while the steam heater 840 is being driven, the control unit 700 may not drive the moving hanger 1000 or may drive the moving hanger 1000 slowly after the driving of the steam heater 840 has finished.
[0726] The control unit 700 may control the section in which the steam supply unit 800 is driven and the section in which the moving hanger 1000 is driven at the second frequency to at least partially overlap.
[0727] The control unit 700 may drive the moving hanger 1000 at the second frequency after the steam supply unit 800 is driven.
[0728] As a result, the clothing processing device of the present invention can drive the moving hanger 1000 or drive it at the fastest speed during at least a portion of the first and second stages, and can not drive the moving hanger 1000 or drive it at the slowest speed before that.
[0729] The above process can be analyzed as follows, focusing on the operation of the moving hanger 1000.
[0730] The control unit 700 may drive the moving hanger 1000 at a first frequency or maintain a stopped state when the temperature inside the inner case is equal to or lower than a set temperature. Also, the control unit 700 may drive the moving hanger 1000 at a second frequency faster than the first frequency when the temperature inside the inner case is equal to or higher than a set temperature.
[0731] After driving the moving hanger 1000 at the second frequency for a reference time, the control unit 700 may then drive the moving hanger 1000 at a third frequency slower than the second frequency.
[0732] The control unit 700 can drive the moving hanger 1000 at a third frequency slower than the second frequency when the temperature rise rate inside the inner case exceeds a reference value or when the temperature inside the inner case reaches a drying temperature higher than the set temperature.
[0733] The control unit 700 can set different driving frequencies of the moving hanger 1000 depending on the temperature inside the inner case 200 .
[0734] Specifically, the control unit 700 can drive the moving hanger 1000 at a first frequency until the temperature inside the inner case reaches a set temperature, and after the temperature inside the inner case reaches the set temperature, can drive it at a second frequency faster than the first frequency.
[0735] In addition, the control unit 700 may drive the moving hanger 1000 at a third frequency slower than the second frequency in the section after the temperature inside the inner case reaches a drying temperature higher than the set temperature.
[0736] The control unit 700 may drive the moving hanger 1000 at the second frequency for a set time, and then drive the moving hanger 1000 at a third frequency slower than the second frequency.
[0737] The second frequency (2 rpm) can be set as the fastest frequency at which the moving hanger is driven during the execution of the course.
[0738] When the moisture content of the clothes falls below the moisture content removal level, the third stage can be executed. The third stage corresponds to a section where the temperature rise rate inside the inner case 200 rises above the reference value again. The wrinkle removal section (A) can be completed before the third stage. Therefore, the steam heater 840 can be completed before the third stage, and the steam heater 840 can be turned off during and after the third stage.
[0739] When the temperature inside the inner case 200 reaches or exceeds the drying temperature, the control unit 700 stops the operation of the compressor 342 and can at least partially maintain the operation of the blower fan 352.
[0740] Meanwhile, the clothing treatment device of the present invention can drive the second heater 842 when the steam heater 840 and the compressor 342 are driven simultaneously in the drying course including the wrinkle removal section (A). This allows a smaller amount of steam to be supplied to the inside of the inner case 200, preventing the possibility of the moisture content of the clothing becoming too high, and allows the device to focus on raising only the temperature inside the inner case 200 above the set temperature.
[0741] The amount of power of the second heater 842 can be set so that the amount of steam generated from the second heater 842 corresponds to a range of 50 to 150% of the amount of moisture that can be dehumidified by the evaporator.
[0742] In addition, the amount of water used and energy consumption when raising the temperature inside the inner case 200 to a set temperature or higher can be minimized.
[0743] Meanwhile, the steam heater 840 is stopped from operating at least during the second stage, which corresponds to the section where the temperature rise rate is below a reference value or the temperature change range inside the inner case 200 is below a predetermined range, so it can be considered that the operation of the first heater or the second heater is stopped during the section where the temperature change range inside the inner case is below a predetermined range.
[0744] The predetermined range may correspond to 5 degrees.
[0745] Furthermore, since the clothing treatment device of the present invention cuts off the steam supply after the third stage in the control method, it can be considered that the steam heater is turned off after the drying temperature is reached.
[0746] FIG. 26 shows another embodiment of the drying course executed in the clothes treating device of the present invention.
[0747] In the clothes treating apparatus of the present invention, the steam heater 840 and the compressor 342 do not need to be driven simultaneously in the wrinkle removing section (A).
[0748] That is, the clothing treatment device of the present invention can always drive the steam heater 840 at maximum power, and the steam heater 840 may be designed as a single heater instead of a first heater and a second heater.
[0749] In the following, in order to avoid overlapping explanations with the above-described embodiment, other contents will be mainly described.
[0750] When the drying course is executed, the clothes treating apparatus of the present invention can execute a preparatory step of driving the compressor 342 to raise the temperature of the refrigerant circulating through the heat supply unit 340.
[0751] The preparation step may correspond to increasing the operating RPM of the compressor 342 to a maximum RPM and increasing the temperature of the refrigerant to a target temperature at which a drying course can be performed.
[0752] The preparation step can be performed up to a time (ta).
[0753] When the preparation step is performed, the clothing treatment device of the present invention can perform the first step of driving the steam heater 840.
[0754] The first step may correspond to driving a single heater at maximum output if the steam heater 840 is provided as a single heater, or driving all heaters if the steam heater 840 is configured with multiple heaters.
[0755] When the steam heater 840 is driven at maximum output, it cannot be driven simultaneously with the compressor 342. However, by driving the steam heater 840 at maximum output, the temperature inside the inner case 200 can be raised to a set temperature or higher more quickly.
[0756] The control unit 700 can increase the internal temperature of the inner case 200 to a guaranteed temperature equal to or higher than a set temperature.
[0757] The guaranteed temperature may correspond to a temperature that can ensure that the internal temperature of the inner case 200 is maintained above the set temperature for a set time when the steam heater 840 is stopped and the compressor 342 is driven again.
[0758] The first step can be performed up to time b (tb).
[0759] In the first step, the control unit 700 can constantly drive the steam heater 840, or can drive the steam heater 840 intermittently and repeatedly.
[0760] When the first step is completed, the control unit 700 can shut off the steam heater 840 and drive the compressor 342 and the blower fan 352 .
[0761] When the blower fan 352 is driven and air flows into the inner case 200, the moisture contained in the clothes evaporates and absorbs the heat of vaporization, causing the temperature inside the inner case 200 to drop and may become lower than the set temperature until time c (tc) is reached.
[0762] However, the temperature inside the inner case 200 stops decreasing and starts to rise again due to the supply of hot air by the preheating step performed earlier and the operation of the compressor 342. Therefore, from time c, the temperature inside the inner case 200 may again become higher than the set temperature.
[0763] From time b (tb) to time c (tb) and thereafter until time d (tb) when the temperature rise rate exceeds the reference value, the temperature rise rate is always below the reference value. Therefore, the period from time b (tb) to time d (tb) can be defined as the second stage.
[0764] The wrinkle removal section (A) can be completed if the temperature inside the inner case 200 reaches a set temperature during the second step.
[0765] The wrinkle removal section (A) is a section where the temperature where the clothes are placed is above the set temperature, the moisture content of the clothes corresponds to the removal moisture content, and all the removal conditions are met as long as a removal physical force is applied.
[0766] The control unit 700 may enter the wrinkle removal section (A) when the temperature inside the inner case 200 begins to reach at least the second set temperature.
[0767] The wrinkle removal section (A) is fulfilled in the second stage, that is, in the second stage, the moisture content of the clothes fulfills the moisture removal requirement, and the temperature inside the inner case is equal to or higher than the set temperature.
[0768] Therefore, the control unit 700 can drive the moving hanger 1000 at least in the wrinkle removal section (A) during the drying course, thereby applying a removing physical force to the clothes.
[0769] As a result, all the removal conditions are met in the wrinkle removal section (A), and wrinkles and creases in the clothes can be removed.
[0770] The wrinkle removal section (A) can be completed before time d (tb), which is the entry section of the third stage at which the temperature rise rate inside the inner case 200 becomes higher than the reference value.
[0771] The third step may be performed until the temperature inside the inner case 200 reaches a drying temperature or higher (tf).
[0772] From the second stage to the third stage, the compressor 342 may be kept operating, and the steam heater 840 may be shut off.
[0773] 28(d), the control unit 700 can drive the moving hanger 1000 in the wrinkle removal section (A). If the control unit 700 has not driven the moving hanger 1000 before the wrinkle removal section (A), the control unit 700 can drive the moving hanger 1000 in the wrinkle removal section (A) for at least a set time.
[0774] The control unit 700 may be configured to operate the compressor 342 and the moving hanger 1000 in an overlapping manner at least in a part of the range, but not operate the compressor 342 and the steam heater 840 in an overlapping manner.
[0775] Also, the moving hanger 1000 can be driven simultaneously while the steam heater 840 is being driven. The moving hanger 1000 can be driven before or after the steam heater 840 is driven.
[0776] In addition, if the control unit 700 has driven the moving hanger at a first frequency (1 rpm) before the wrinkle removal section (A), it can drive it at a second frequency (2 rpm) faster than the first frequency during the wrinkle removal section (A).
[0777] As a result, by applying a physical force equal to or greater than the removal physical force to the clothes in the wrinkle removal section (A), the removal condition is further satisfied, and wrinkles and creases in the clothes can be reliably removed.
[0778] After the wrinkle removal section (A), the control unit 700 can stop driving the moving hanger 1000 or drive the moving hanger 1000 at a third frequency (3 rpm) slower than the second frequency, thereby preventing overload of the moving hanger 1000 during the drying course and saving energy.
[0779] The first frequency may be set lower than the third frequency, thereby preventing the moving hanger 1000 from consuming excessive energy to shake heavy clothes with high moisture content, and minimizing vibrations generated in the entire clothes treating device.
[0780] When the control unit 700 drives the moving hanger 1000 while the steam heater 840 is being driven, the control unit 700 can drive the moving hanger 1000 at a higher speed in at least a portion of the section after the driving of the steam heater 840 has finished, and thereafter drive the moving hanger 1000 at a lower speed.
[0781] After the steam supply unit 800 is driven, the control unit 700 may drive the moving hanger 1000 at a second frequency.
[0782] As a result, the clothing treatment device of the present invention can drive the moving hanger 1000 or drive it as quickly as possible during at least a portion of the constant rate phase, and not drive the moving hanger 1000 or drive it as slowly as possible before that.
[0783] If we describe the above process focusing on the drive of the moving hanger 1000, it can be analyzed as follows.
[0784] When the temperature inside the inner case is equal to or lower than a set temperature, the control unit 700 may drive the moving hanger 1000 at a first frequency or maintain a stopped state.
[0785] Also, the control unit 700 may drive the moving hanger 1000 at a second frequency faster than the first frequency from the section where the temperature inside the inner case exceeds the set temperature for the second time.
[0786] The control unit 700 may drive the moving hanger 1000 at a second frequency for a set time, and then drive the moving hanger 1000 at a third frequency lower than the second frequency.
[0787] The control unit 700 can drive the moving hanger 1000 at a third frequency lower than the second frequency when the temperature rise rate inside the inner case becomes higher than a reference value or when the temperature inside the inner case becomes higher than a drying temperature higher than the set temperature.
[0788] The control unit 700 can set different driving frequencies of the moving hanger 1000 depending on the temperature inside the inner case 200 .
[0789] Specifically, the control unit 700 can drive the moving hanger 1000 at a first frequency until the temperature inside the inner case rises for the second time and reaches the set temperature, and then drive the moving hanger 1000 at a second frequency that is faster than the first frequency after the temperature inside the inner case rises for the second time and reaches the set temperature.
[0790] The control unit 700 may drive the moving hanger 1000 at a third frequency lower than the second frequency in a section after the temperature inside the inner case reaches a drying temperature higher than the set temperature.
[0791] The control unit 700 may drive the moving hanger 1000 at the second frequency for a set time, and then drive the moving hanger 1000 at a third frequency slower than the second frequency.
[0792] The second frequency (2 rpm) can be set to the fastest frequency at which the moving hanger operates during course execution.
[0793] When the temperature inside the inner case 200 reaches or exceeds the drying temperature, the control unit 700 can stop the operation of the compressor 342 and at least partially maintain the operation of the blower fan 352 .
[0794] The present invention can be embodied in various forms, and the scope of the invention is not limited to the above-described embodiments. Therefore, if a modified embodiment includes elements recited in the claims of the present invention, it should be considered to fall within the scope of the invention.
