Description

Technical Field

[0001] This utility model relates to a garment processing device. More specifically, it relates to a garment processing device that dries clothes by rotating the drum after they are placed into it. Background Technology

[0002] A garment handling device is a device capable of washing, drying, or both washing and drying garments (items to be washed or dried). It includes washing machines, dryers, and washing machines with drying functions.

[0003] Recently, clothing drying devices have emerged that utilize heat pumps to centrally dry clothes. These existing devices supply hot air generated in the heat pump to the clothes housed inside the drum, simultaneously rotating the drum and exposing the clothes evenly to the hot air, thereby drying the clothes.

[0004] Such a garment processing device is configured to have a drum with its rotation axis parallel to the ground or its inlet positioned in front, i.e., a front-load type, and is configured to dry the garments by supplying hot air into the drum while the drum is rotating, with the garments contained within it. Thus, the garments, positioned at the bottom of the drum, are evenly exposed to the hot air and dried as they rise and fall with the rotation of the drum.

[0005] However, the purpose of this garment processing device is to dry clothes, so initially damp clothes are put into the drum.

[0006] In this garment handling apparatus, as moisture evaporates during the drying process, the weight of the garments inside the drum decreases. Therefore, the motor load decreases during the drying process. However, in the initial stages of the drying process, due to the weight of the garments, including moisture, the power consumption when driving the motor may be excessive compared to the later stages. Furthermore, compared to the dry state, the rising height of damp garments may be less, potentially leading to knotting or tangling issues as they move within the drum. Therefore, in this garment handling apparatus, the drum rotates more continuously in the initial stages of the drying process than in the later stages, which may be detrimental to power consumption or stable drum rotation.

[0007] Furthermore, even with the same garment, damp clothing is not only heavier than dry clothing, but also has higher adhesion, resulting in very strong adhesion between the inner walls of the drum or between the garments themselves. Therefore, when the drum containing damp clothing is rotated, the damp clothing may not rise sufficiently due to its weight, and may become knotted or tangled as it moves inside the drum.

[0008] Furthermore, when clothes are tangled or knotted while damp, they may become wrinkled or damaged even after drying.

[0009] Furthermore, as the roller rotates, the knotted or tangled clothing may push against the door that closes the roller inlet as it moves, potentially causing moisture and hot air inside the roller to escape to the outside.

[0010] Furthermore, when clothing becomes tangled or knotted, an imbalance occurs inside the drum, which may cause overload in the motor that rotates the drum or hinder the normal operation of the motor.

[0011] Recently, a garment processing device has emerged that reduces the rotation speed of the drum when the garment's humidity is low and increases the drum's rotation speed when the garment's humidity is high, thereby preventing wrinkles in the garment. (Refer to European Patent Publication 2008 / 000726)

[0012] However, in the existing garment processing apparatus described above, when dealing with damp garments with high humidity, the drum rotates at a higher speed than when the garments are dry. Therefore, the existing problem of exacerbating the tangling or knotting of the garments still exists.

[0013] Furthermore, a garment processing device has been developed that removes wrinkles from garments by intermittently rotating a drum at the end of the drying process. (Refer to Korean Patent Publication No. 10-2022-0144288)

[0014] However, this garment processing device also has the following problems: it only reduces the actual rotation rate of the drum in the later stage of the drying process to make the drum rotate intermittently, while in the early stage of the drying process, the drum rotates at high speed for a long time, making it difficult to solve the problem of damp clothes tangling or knotting.

[0015] Furthermore, as a dryer with a washing function, a garment handling device has emerged that employs a control method that drives the drum at a slower speed in the later stages than in the initial stages and shortens the continuous rotation time of the drum, so as to eliminate tangles in the garments when the drying process is performed after the dehydration process (see Japanese Patent Publication No. 2018-235440).

[0016] However, this garment processing device also has the following problems: compared with the later stages of the drying process, the drum rotates faster in the early stages of the drying process, and the drum rotates continuously for a longer time, thus failing to improve the knotting or tangling of the garments.

[0017] Clothes are more likely to get tangled or knotted in large quantities than in small quantities. That is, with fewer clothes, there is more space inside the drum to move without contacting other clothes compared to with a large quantity. Therefore, even if the drum rotates continuously, the probability of clothes getting tangled or knotted is lower than with a large quantity of clothes.

[0018] However, existing garment handling devices do not yet disclose a technology for controlling the rotational speed and operating rate of the drum to vary depending on the weight of the garments being fed into the drum. Utility Model Content

[0019] The problem to be solved by the utility model

[0020] The problem to be solved by this utility model is to provide a clothing processing device that can minimize the tangling or knotting of damp clothing during the drying process.

[0021] The problem to be solved by this utility model is to provide a clothing processing device that can eliminate the tangling or knotting of clothing during the drying process.

[0022] The problem to be solved by this utility model is to provide a clothing processing device that can minimize the changes in humidity and temperature in the external space where the clothing processing device is located during the drying process.

[0023] The problem to be solved by this invention is to provide a garment processing device that can save power consumption of the drive unit that rotates the drum during the drying process.

[0024] The problem to be solved by this utility model is to provide a clothing processing device that can provide the optimal rotation mode of the drum according to the degree of dryness of the clothes during the drying process.

[0025] Methods for solving problems

[0026] To address the aforementioned issues, this invention provides a clothing handling device comprising: a drum for holding clothing; a drive unit for rotating the drum; a circulation pipe housing a circulation fan for circulating air inside the drum; a heat exchanger disposed inside the circulation pipe for heating the air; and a compressor for supplying refrigerant to the heat exchanger for heating the air. The drive unit is configured to cause the drum to repeatedly perform stationary and rotating actions, wherein the drum rotates and remains stationary more times per unit time during periods of increased compressor speed than during periods of decreased compressor speed.

[0027] In the clothing processing device of this utility model, the roller rotates and stops the most times per unit time during the range of the lowest rotation speed of the compressor.

[0028] In the garment processing device of this utility model, the roller rotates in the same manner with the same ratio of rotation and stillness per unit time in the following two intervals: a part of the interval in which the speed of the compressor decreases in stages; and the interval in which the speed of the compressor increases.

[0029] In the clothing processing device of this utility model, compared with the range where the compressor's revolutions per minute decreases in stages, the drum rotates and remains still more times per unit time during the range where the compressor's revolutions per minute is the lowest.

[0030] In the garment processing device of this invention, during the range where the compressor's revolutions per minute increase, the drum rotates with a longer period of continuous stillness than continuous rotation.

[0031] In the garment processing device of this invention, during the range where the compressor's revolutions per minute increase, the roller rotates in such a manner that the time spent rotating and the time spent stationary are the same per unit time.

[0032] In the garment processing device of this invention, during the range where the compressor's revolutions per minute increase, the roller rotates in such a way that the time spent at rest per unit time is longer than the time spent rotating.

[0033] In the clothing processing device of this utility model, during the interval where the compressor's revolutions per minute decreases in stages or during the interval where the compressor's revolutions per minute is at its lowest, the drum rotates after remaining stationary for a longer period of time per unit time.

[0034] In the clothing processing device of this utility model, compared with the range where the compressor's revolutions per minute increase, the drum rotates for a longer time and then comes to rest during the range where the compressor's revolutions per minute is lowest and the range where the compressor's revolutions per minute decreases in stages.

[0035] In the garment processing device of this utility model, compared with the range where the compressor's revolutions per minute increases, the drum rotates more continuously and for a longer period of time before coming to rest in at least one of the ranges where the compressor's revolutions per minute is lowest and the range where the compressor's revolutions per minute decreases in stages.

[0036] To address the aforementioned issues, this invention provides a garment handling device and its control method, which can optimally apply the forward and reverse stirring of the drum and the agitation rate in various stages of the drying process to solve problems such as increased garment tangling, constraints on the motor that rotates the drum, moisture leakage at the door, and reduced coefficient of performance (evaporation efficiency). For example, the agitation rate can be controlled to be lower in the initial stage of the drying process than in the later stage.

[0037] In particular, in the garment processing device of this invention, when the garment processing device is configured with a large capacity, resulting in a smaller liquor ratio (Liter / kg) when the drum capacity is divided by the maximum drying load, in order to prevent the corresponding problems from aggravating, the forward and reverse stirring and actual operation rate of the drum can be optimally designed in each interval of the drying process.

[0038] To address the aforementioned issues, this invention provides a garment processing device comprising: a housing having an opening; a door for opening and closing the opening; a roller rotatably disposed inside the housing, the roller accommodating garments; a heat supply unit for supplying air into the roller to dry the garments; and a control unit for controlling the heat supply unit to execute the drying process of the garments.

[0039] The drum can be controlled to rotate in such a way that, compared to the end of the drying process when the internal temperature is above the reference value, the initial stage of the drying process when the internal temperature is below the reference value has a lower actual rate (ratio of rotation time to stationary time) or more changes in rotation direction.

[0053] When the drum rotates, it can rotate at a speed that allows the clothes to move to a position higher than the center of rotation of the drum during the drying process.

[0054] The drum can rotate at the same speed throughout the entire drying process.

[0055] The roller can be designed with a ratio (bath ratio) of 13 to 14 between the maximum volume of clothing it can hold and the maximum weight it can hold.

[0163] The support portion 400 may include: a front plate 410 that supports the front of the roller 200 so as to be rotatable; and a rear plate 420 that supports the rear of the roller 200 so as to be rotatable.

[0164] The front plate 410 and the rear plate 420 can be configured as plate shapes opposite to the roller 200 and can be arranged perpendicular to the ground.

[0165] The front plate 410 and the rear plate 420 may be provided with a plurality of rollers supporting the roller 200.

[0166] The garment processing device of this utility model may further include a drive unit 500 for rotating the roller 200.

[0167] The drive unit 500 may include: a motor 510 that provides power to rotate the roller 200; a pulley 550 that rotates in conjunction with the motor 510; and a conveyor belt 570 that connects the pulley 550 and the roller 200 to transmit rotational force.

[0168] The garment processing device of this invention may further include a base 800 disposed at a position lower than the roller 200. The base 800 is configured to provide space for mounting electrical components such as the motor 510, and may form the bottom surface of the garment processing device of this invention, or may support the bottom panel disposed on the housing 100.

[0169] The garment processing device of this utility model may include a circulation pipe 820 disposed on the base 800 to circulate air in the roller 200. The circulation pipe 820 may include an exhaust pipe 823 extending rearward of the roller 200 to move air, and may also include an inlet pipe 821 extending forward of the roller 200 to draw in air.

[0170] The garment processing device of this utility model may further include a heat supply unit 900, which is disposed in the circulation pipe 820 and exchanges heat with the air discharged from the drum 200.

[0171] The heat supply unit 900 may include: an evaporator 910 disposed in a circulation pipe 820 for cooling air discharged from the drum 200; a condenser 920 disposed downstream of the evaporator 910 for heating air passing through the evaporator 910; a compressor 930 for supplying refrigerant to the condenser for heating the air; and an expansion valve 940 for expanding the refrigerant passing through the condenser 920 to reduce the temperature of the refrigerant.

[0172] The compressor and the expansion valve 940 are located outside the circulation pipe 820.

[0173] The garment processing device of this utility model may further include a circulating fan 950, which is configured to be combined with the circulating pipe 820 to circulate the air inside the drum.

[0174] The circulating fan 950 may further include: an impeller disposed inside the circulating pipe 820; and a fan motor 951 mounted on the impeller and outside the circulating pipe 820 to rotate the impeller.

[0175] The fan motor 951 can be understood as a motor installed behind the circulation pipe 820 and driving the circulation fan 950.

[0176] The fan motor 951 can be separated from the drive motor 510 of the drive unit 500, so that the fan motor 951 can be controlled independently of the drive motor 510.

[0177] As a result, the circulating fan 950 can be controlled independently of the drive unit 500. In other words, the drive unit 500 can repeatedly perform stationary and driven operations separately from the circulating fan 950.

[0178] Therefore, the drive unit 500 can be configured to rotate the roller 200 independently of the circulating fan 950.

[0179] Figure 3 It shows Figure 2 The base structure of the garment processing device.

[0180] The base 800 can be divided into the circulation pipe 820 and the device mounting section 810 disposed outside the circulation pipe 820.

[0181] The circulation pipe 820 may include a movable pipe 822 disposed on one side of the base 800, and equipped with an evaporator 910 and a condenser 920. The movable pipe 822 may be configured to connect the inflow pipe 821 and the discharge pipe 823.

[0182] A circulating fan 950 can be installed in the discharge pipe 823 to move the air. The circulating fan 950 can create negative pressure inside the circulation pipe 820, guiding air to flow in from the inlet pipe 821 (direction I) and to discharge into the outlet pipe 823 (direction II).

[0183] The compressor 930, drive unit 500, and circulating fan 950 can be installed in the device installation unit 810 arranged on one side of the moving pipe 820.

[0184] A water collection section for collecting water condensed in the evaporator 910 may be disposed between the compressor 930 and the moving pipe 820. A drain pump may be provided in the water collection section to drain the water into the drain tank 120.

[0185] The movable conduit 820 can be configured off-center from one side of the base 800. The width of the movable conduit 820 can be approximately half the width of the base 800.

[0186] Figure 4 Another embodiment of the internal structure of the garment handling device of this utility model is shown.

[0187] The garment handling device of this utility model may include: a roller 200 housed inside the housing 100 for holding garments; a drive unit 500 for rotating the roller 200; a heat exchange unit 900 configured to supply hot air to the roller 200; and a base 800 having a circulation pipe 820. The circulation pipe 820 is configured to communicate with the roller 200. Air discharged from the roller 200 can be supplied to the circulation pipe 820. Furthermore, air discharged from the circulation pipe 820 can be supplied back to the roller 200.

[0188] The drive unit may include a drive unit 500 that provides power to rotate the roller 200. The drive unit may be configured to be directly connected to the roller 200 to rotate it. For example, the drive unit may be configured as a DD (Direct Drive unit) type. Thus, the drive unit can omit structures such as conveyor belts and pulleys and directly rotate the roller 200, thereby controlling the rotation direction or speed of the roller 200.

[0189] The drive unit 500 can rotate at a high speed of revolutions per minute (RPM). For example, the clothes inside the roller 200 can be rotated at a speed much greater than that required to rotate while still attached to the inner wall of the roller 200.

[0190] However, if the clothes inside the drum 200 continue to adhere to the inner wall of the drum 200 while rotating, the part adhering to the inner wall of the drum will not be exposed to hot air, thus resulting in a reduction in drying efficiency.

[0191] If the rotor 520 is rotated at a low speed per minute in order to make the clothes roll or agitate inside the drum 200 without adhering to the inner wall of the drum 200, problems may occur in which the output or torque that the drive unit can generate cannot be properly utilized.

[0192] Therefore, the drive unit of the clothing handling device of this utility model may also include a reducer 600, which can utilize the maximum output of the drive unit 500 by reducing the revolutions per minute, while also increasing the torque.

[0193] The drum 200 can be configured in a cylindrical shape to accommodate clothing. Furthermore, unlike a drum used for washing, the drum 200 used only for drying does not require water to be added inside, and there is no need to drain any condensed liquid water inside the drum 200 to the outside. Therefore, the through-hole formed along the circumferential surface can be omitted from the drum 200. That is, the drum 200 used only for drying can be formed differently from the drum 200 used for washing.

[0194] The roller 200 can be configured as a single cylindrical shape, but it can also be made into a shape that combines a roller body 210 with a rear roller back 220.

[0195] A loading port 211 for loading and unloading clothes may be provided at the front of the drum body 210. A drive unit for rotating the drum may be connected to the rear of the drum back 220. The drum body 210 and the drum back 220 may also be connected by fastening components such as bolts, but are not limited thereto. Various methods can be used to connect the drum body 210 and the drum back 220 as long as they are connected so that they can rotate together.

[0196] A lifting element 213 may be provided in the drum body 210. The lifting element 213 pulls the clothes inside upwards, so that the clothes contained inside can be mixed as the drum rotates. When the drum 200 rotates, the clothes contained inside can repeatedly rise and fall through the lifting element 213. The clothes contained inside the drum 200 can be evenly exposed to hot air during repeated rising and falling. Therefore, it has the effect of improving drying efficiency and shortening drying time.

[0197] Reinforcing ribs 212 may be formed on the circumferential surface of the roller body 210. The reinforcing ribs 212 may be configured to be recessed or protruding along the circumferential surface of the roller 200, either internally or externally. Multiple reinforcing ribs may be provided as described above, and they may be spaced apart from each other. The reinforcing ribs may be arranged in a predetermined pattern on the internal or external surface of the circumferential surface.

[0198] The reinforcing ribs 212 increase the rigidity of the drum body 210. Therefore, even when a large amount of clothing is contained within the drum body 210, or when a sudden rotational force is received by the drive unit, the drum body 210 can be prevented from twisting. Furthermore, compared to a case where the circumferential surface of the drum body 210 is flat, the presence of the reinforcing ribs 212 increases the distance between the clothing and the inner circumferential surface, allowing hot air supplied to the drum 200 to flow more effectively between the clothing and the drum 200. The reinforcing ribs improve the durability of the drum and enhance the drying efficiency of the clothing handling apparatus.

[0199] Typically, in the case of a DD-type washing machine, the drive unit is fixed to the outer tub that houses the drum 200, and the drum 200 can be connected to the drive unit and supported by the outer tub. However, since the clothing handling device of this invention is configured to centrally perform the drying process, the outer tub fixed to the housing 100 for housing the drum 200 is omitted.

[0200] Therefore, the garment processing device of this utility model may further include a support part 400, which is configured to fix or support the roller 200 or the drive part inside the housing 100.

[0201] The support portion 400 may include: a front plate 410 disposed in front of the roller 200; and a rear plate 420 disposed behind the roller 200. The front plate 410 and the rear plate 420 may be plate-shaped and configured to face the front and rear of the roller 200, respectively. The distance between the front plate 410 and the rear plate 420 may be set to be the same as or longer than the length of the roller 200. The front plate 410 and the rear plate 420 may be fixedly supported on the bottom surface of the housing 100 or the base 800.

[0202] The front panel 410 can be disposed between the front panel forming the front surface of the housing and the roller 200. Furthermore, the front panel 410 may have an insertion connection hole 412 communicating with the insertion port 211. Because the front panel 410 has the insertion connection hole 412, it can both support the front surface of the roller 200 and allow clothing to be inserted into or removed from the roller 200.

[0203] The front plate 410 may include a pipe connection portion 416 disposed on the lower side of the inlet communication hole 412. The pipe connection portion 416 may form the lower side surface of the front plate 410.

[0204] The front plate 410 may include a pipe connection hole 417 extending through the pipe connection portion 416. The pipe connection hole 417 is hollow, allowing air discharged through the roller's inlet 211 to be guided to the lower side of the roller 200. Furthermore, air discharged through the roller 200 can be guided to a circulation pipe 820 located at the lower part of the roller 200.

[0205] A filter section (not shown) may be provided in the pipe connection hole 417 to filter out lint or larger particles produced by clothing. The filter section has the following effects: it can prevent impurities from accumulating inside the clothing processing device by filtering the air discharged from the drum 200, and it can prevent impurities from accumulating and hindering air circulation.

[0206] Since the inlet 211 is located at the front, it is preferable that the drive unit is located on the rear plate 420 rather than the front plate 410. The drive unit can be configured to be mounted on and supported by the rear plate 420. Thus, the drive unit can rotate the roller 200 while being stably fixed in position by the rear plate 420.

[0207] At least one of the front plate 410 and the rear plate 420 can support the roller 200 so that it can rotate. At least one of the front plate 410 and the rear plate 420 can accommodate the front end or the rear end of the roller 200 so that it can rotate.

[0208] For example, the front of the roller 200 can be supported by the front plate 410 to allow it to rotate, and the rear of the roller 200 can be spaced apart from the rear plate 420 and indirectly supported by the rear plate 420 through connection with the drive unit 500 mounted on the rear plate 420. This minimizes the area of ​​contact or friction between the roller 200 and the support unit 400, thereby preventing unnecessary noise or vibration.

[0209] Of course, the roller 200 can also be configured to be supported by both the front plate 410 and the rear plate 420 so that it can rotate.

[0210] One or more support wheels 415 supporting the front of the roller 200 may be provided on the lower part of the front plate 410. The support wheels 415 may be rotatably disposed on the back of the front plate 410. The support wheels 415 may rotate in contact with the lower part of the roller 200.

[0211] When the roller 200 rotates via the drive unit, it can be supported by a rotating shaft connected to a reducer at the rear. When clothing is contained within the roller 200, the load applied to the rotating shaft may increase due to the clothing. Therefore, there is a risk that the rotating shaft may bend due to the load.

[0212] With the support wheel 415 supporting the lower front part of the roller 200, the load applied to the rotating shaft can be reduced. Therefore, bending of the rotating shaft can be prevented, thereby preventing noise caused by vibration.

[0213] The support wheels 415 can be positioned symmetrically about the rotation center of the roller 200 to support the load of the roller 200. Preferably, the support wheels 415 are respectively located on the lower left and right sides of the roller 200 to support the roller 200. However, this is not a limitation, and more support wheels 415 can be provided depending on the working environment of the roller 200.

[0214] The circulation pipe 820 provided on the base 800 can form a flow path that allows the air inside the roller 200 to circulate and be reintroduced into the roller 200.

[0215] The circulation pipe 820 may include: an inflow pipe 821 for air discharged from the drum 200 to flow into; an outlet pipe 823 for supplying air to the drum 200; and a moving pipe 822 for connecting the inflow pipe 821 and the outlet pipe 823.

[0216] When air is discharged from the front of the roller 200, the moving pipe 822 can be located on the front side of the circulation pipe 820. Furthermore, the discharge pipe 823 can be located on the rear side of the circulation pipe 820.

[0217] The discharge pipe 823 may also include an air supply section 8231 for discharging air to the outside of the circulation pipe 820, and a circulation fan 950 may be provided in the air supply section.

[0218] The air supply section 8231 can be located behind the discharge pipe 823. The air discharged through the air supply section 8231 can move toward the roller 200.

[0219] A pipe cover 830 may be attached to the upper side of the circulation pipe 820 to cover a portion of the open top surface of the circulation pipe 820. The pipe cover 830 can prevent air from flowing out of the circulation pipe 820. In other words, the pipe cover 830 can form a surface for air circulation.

[0220] Furthermore, the heat exchange section 900 disposed on the base 800 may include: a first heat exchanger 910 disposed inside the circulation pipe 820 for cooling air; and a second heat exchanger 920 disposed inside the circulation pipe 820 for heating the air cooled in the first heat exchanger 910.

[0221] The first heat exchanger 910 can dehumidify the air discharged from the drum 200, and the second heat exchanger 920 can heat the dehumidified air. The heated air can be supplied back to the drum 200 to dry the clothes contained in the drum 200.

[0222] The first heat exchanger 910 and the second heat exchanger 920 can be configured as heat exchangers for refrigerant flow. When configured as heat exchangers for refrigerant flow, the first heat exchanger 910 can be configured as an evaporator, and the second heat exchanger 920 can be configured as a condenser. The refrigerant moving along the first heat exchanger 910 and the second heat exchanger 920 can be configured to exchange heat with air discharged from the drum 200.

[0223] The heat exchange unit 900 may include a circulating fan 950 disposed in the circulation duct 820 to generate airflow within the circulation duct 820. Furthermore, the heat exchange unit 900 may include a fan motor 951 for rotating the circulating fan 950. The circulating fan 950 can be rotated by being powered by the fan motor 951. When the circulating fan 950 is operating, the air dehumidified in the first heat exchanger 910 and heated in the second heat exchanger 920 can move towards the rear of the drum 200.

[0224] The circulating fan 950 can be installed in any one of the inflow pipe 821, the moving pipe 822, or the discharge pipe 823. Since the circulating fan 950 is configured to rotate, it may generate noise when operating. Therefore, it is preferable that the circulating fan 950 is positioned behind the circulating pipe 820.

[0225] The circulating fan 950 can be disposed in the air supply section 8231. Furthermore, the fan motor 951 can be located behind the air supply section 8231. When the circulating fan 950 rotates via the fan motor 951, the air inside the circulating duct 820 can be discharged to the outside of the circulating duct 820 through the air supply section 8231.

[0226] The circulating fan 950 may include an impeller disposed inside the circulating pipe 820, and the fan motor 951 can be understood as a structure that is installed on the impeller and outside the circulating pipe 820 to rotate the impeller.

[0227] The fan motor 951 can be separated from the drive motor 510 of the drive unit 500, so that the fan motor 951 can be controlled independently of the drive motor 510.

[0228] As a result, the circulating fan 950 can be controlled independently of the drive unit 500. In other words, the drive unit 500 can repeatedly perform stationary and driven operations separately from the circulating fan 950.

[0229] To facilitate easy removal of clothing from inside the drum 200, the inlet 211 of the drum 200 is preferably positioned at a relatively high location. Therefore, the circulation pipe 820 and the heat exchange section 900 are preferably located at the lower part of the drum 200.

[0230] A rear plate 420 may be provided behind the roller 200 to guide air discharged from the circulation pipe 820 to the roller 200. The rear plate 420 may be configured to be spaced apart from the back surface 220 of the roller. The circulation pipe 820 can receive air inside the roller 200 through the front plate 410 and supply air to the roller 200 through the rear plate 420. Air discharged from the circulation pipe 820 can be guided to the roller 200 through the rear plate 420.

[0231] The base 800 may also include a connector 850 that guides air discharged from the circulation conduit 820 to the rear panel 420. The connector 850 can guide the discharged air to diffuse evenly throughout the entire area of ​​the rear panel 420.

[0232] The connector 850 can be disposed on the air supply section 8231. That is, the connector 850 can guide the air discharged from the air supply section 8231 to the rear plate 420. The hot air supplied to the rear plate 420 can flow into the interior of the roller 200 through the back side 220 of the roller.

[0233] The roller 200 of the garment handling device of this invention can be directly connected to the drive unit located at the rear of the roller 200 for rotation, rather than being indirectly rotated by connection with a conveyor belt or the like. Therefore, unlike the conventional dryer roller which is configured as a cylindrical shape open at the front and rear, the rear of the roller of the garment handling device of this invention can be covered and directly connected to the drive unit.

[0234] The roller back surface 220 can be configured to cover the rear of the roller body 210 to provide a mating surface that directly engages with the drive unit. That is, the roller back surface 220 can be configured to connect with the drive unit and provide rotational power, thereby enabling the entire roller 200 to rotate. As a result, an inlet 211 for inserting clothing can be formed at the front of the roller body 210, while the rear is covered by the roller back surface 220.

[0235] A bushing portion 300 may be provided on the back surface 220 of the roller to connect the drive unit and the back surface 220. The bushing portion 300 may be provided on the back surface 220 of the roller to form the rotation center of the roller 200. The bushing portion 300 may be integrally formed with the back surface 220 of the roller, but in order to be firmly connected with the rotating shaft that transmits power, it may be made of a material with greater rigidity or durability than the back surface 220 of the roller. The bushing portion 300 may be mounted and connected to the back surface 220 of the roller in a manner coaxial with the rotation center of the back surface 220 of the roller.

[0236] The roller back surface 220 may include: a peripheral portion 221 that engages with the outer peripheral surface of the roller body 210; and a mounting plate 222 disposed on the inner side of the peripheral portion 221 and capable of engaging with the drive portion. The bushing portion 300 may be mounted and engaged with the mounting plate 222. The rotation shaft that rotates the roller is engaged with the mounting plate 222 through the bushing portion 300, thereby achieving a more secure engagement. Furthermore, deformation of the roller back surface 220 can be prevented.

[0237] The roller back surface 220 may include an intake hole 224, which is formed through the peripheral portion 221 and the mounting plate 222, connecting the front and rear sides of the roller back surface 220. Hot air supplied through the circulation pipe 820 can flow into the interior of the roller body 210 through the intake hole 224. The intake hole 224 may be composed of multiple holes provided through the roller back surface 220, or it may be formed by a mesh.

[0238] The rear of the rear plate 420 may include: a drive unit 500 that rotates the roller 200; and a reducer 600 that reduces the rotational force of the drive unit 500 and transmits it to the roller 200.

[0239] A drive unit 500 may be disposed at the rear of the rear plate 420. Furthermore, the drive unit 500 can be coupled to the rear of the rear plate 420 via the reducer 600.

[0240] The reducer 600 can be fixed to the back of the rear plate 420, and the drive unit 500 can be coupled to the back of the reducer 600. That is, the rear plate 420 can provide a support surface for supporting the reducer 600 or the drive unit 500. However, it is not limited to this; the drive unit 500 can also be coupled to the rear plate 420.

[0241] Figure 5a , Figure 5b The base and back plate provided in one embodiment of the present invention are shown.

[0242] Reference Figure 5a The rear plate 420 can be located behind the drum. The rear plate 420 can guide the hot air discharged from the circulation pipe 820 to the drum. That is, the rear plate 420 can be located behind the drum to form a flow path so that the hot air is evenly supplied to the entire drum.

[0243] The rear plate 420 may include: a rear panel 421 opposite to the back of the roller; and a conduit 423 recessed rearward from the rear panel 421 to form a flow path. The conduit 423 may be formed by applying pressure rearward from the rear panel 421. The conduit 423 may be configured to accommodate a portion of the back of the roller.

[0244] The pipe section 423 may include an inflow section 4233 located behind the circulation flow path section and a flow section 4231 located behind the drum. The flow section 4231 may be configured to accommodate a portion of the drum. The flow section 4231 may accommodate a portion of the drum to form a flow path behind the drum.

[0245] The flow portion 4231 can be configured as annular, opposite to the suction hole formed on the back of the roller. The flow portion 4231 can be configured to be recessed from the rear panel 421. That is, the flow portion 4231 can be configured to be open at the front, forming a flow path together with the back of the roller.

[0246] With the flow section 4231 configured to be open at the front, the hot air moving towards the flow section 4231 can directly reach the drum without passing through any additional structure. Therefore, heat loss during the passage of hot air through additional structures can be prevented. In other words, it has the effect of reducing heat loss of the hot air and improving drying efficiency.

[0247] The rear plate 420 may include a mounting portion 425 disposed radially inside the flow portion 4231. The mounting portion 425 may provide space for engaging the reducer 600 or the drive portion 500. That is, the rear plate 420 may include the mounting portion 425 disposed on the inner side and the flow portion 4231 disposed annularly on the radially outer side of the mounting portion 425.

[0248] Specifically, the flow section 4231 may include a flow outer periphery 4231a that surrounds the internal space through which the hot air flows from the outside. Furthermore, the flow section 4231 may include a flow inner periphery 4231b that surrounds the internal space through which the hot air flows from the inside. That is, the flow outer periphery 4231a may form the outer periphery of the flow section 4231, and the flow inner periphery 4231b may form the inner periphery of the flow section 4231.

[0249] Furthermore, the flow section 4231 may include a flow recessed surface 4232, which forms the rear side of the flow path through which the hot air moves. The flow recessed surface 4232 may be configured to connect the outer flow peripheral section 4231a and the inner flow peripheral section 4231b. That is, the inner flow peripheral section 4231b, the outer flow peripheral section 4231a, and the flow recessed surface 4232 can form a space for the flow of hot air discharged from the circulation pipe 820.

[0250] Furthermore, the flow recessed surface 4232 can prevent hot air from leaking backward, thereby guiding hot air towards the roller. That is, the flow recessed surface 4232 can refer to the recessed surface of the flow section 4231.

[0251] The inflow portion 4233 may be located opposite to the circulation pipe 820. The inflow portion may be located opposite to the air supply portion 8231. The inflow portion 4233 may be configured to be recessed rearward from the rear panel 421 to prevent interference with the air supply portion 8231. The upper side of the inflow portion 4233 may be connected to the flow portion 4231.

[0252] One embodiment of the present invention provides a garment handling apparatus that may include a connector 850 connected to an air supply section 8231. The connector 850 guides hot air discharged from the air supply section 8231 to a flow section 4231. The connector 850 may have a flow path formed internally to guide the hot air discharged from the air supply section 4231 to the flow section 4231. That is, the connector 850 may form a flow path connecting the air supply section 8231 and the flow section 4231. The cross-sectional area of ​​the flow path disposed inside the connector 850 may be configured to increase as it moves further away from the air supply section 8231.

[0253] The connector 850 can be located opposite the inflow portion 4233. The inflow portion 4233 can be recessed rearward to prevent interference with the connector 850. Furthermore, the upper end of the connector 850 can be configured to divide the flow portion 4231 and the inflow portion 4233. That is, hot air discharged from the connector 850 can flow into the flow portion 4231, thereby preventing it from flowing into the inflow portion 4233.

[0254] The connector 850 can be configured to uniformly supply hot air to the flow section 4231. The connector 850 can be configured such that its width increases as it moves further away from the air supply section 8231. The upper end of the connector 850 can be located at a position along the circumferential extension line of the outer periphery of the flow section 4231a.

[0255] Therefore, the hot air discharged from connector 850 can be entirely supplied to the flow section 4231 without moving towards the inflow section 4233. Connector 850 prevents hot air from concentrating on one side of the flow section 4231, thereby supplying hot air evenly into the drum. This improves the drying efficiency of clothes.

[0256] The connector 850 can be configured such that its width increases towards the upstream side, thereby reducing the velocity of the hot air moving along the connector 850 in the flow direction. That is, the connector 850 can function as a diffuser to regulate the velocity of the hot air. The connector 850 can prevent the concentrated supply of hot air to only a specific part of the drum by reducing the velocity of the hot air.

[0257] By adjusting the shape of the connector 850, the inflow portion 4233, configured to face the connector 850 and prevent interference with the connector 850, can also be configured such that its width increases as it moves further away from the air supply portion 8231. By adjusting the shape of the inflow portion 4233, when viewed from the front, the overall shape of the pipe portion 423 can be a shape such as "9".

[0258] Since the drum is configured to rotate during the drying process, it may be configured to be spaced a predetermined distance from the flow section 4231. Hot air may flow out through this space.

[0259] Therefore, the garment handling apparatus may also include a seal 450 to prevent hot air leakage into the space between the roller and the flow section 4231. The seal 450 may be located along the periphery of the flow section 4231.

[0260] The sealing portion 450 may include a first seal 451 disposed along the outer periphery of the flow portion 4231. The first seal 451 may be disposed between the roller and the outer periphery of the flow portion 4231. Furthermore, the first seal 451 is configured to contact the entire back surface 220 of the roller and the rear plate 420, thereby more effectively preventing leakage.

[0261] On the other hand, the first seal 451 can be configured to contact the front surface of the connector 850. Furthermore, the first seal 451 can be configured to contact the upper end of the connector 850. The connector 850, together with the flow portion 4231, can form a flow path for the flow of hot air. Therefore, by configuring the first seal 451 to contact the connector 850, hot air leakage between the roller and the connector 850 can be prevented.

[0262] The sealing portion 450 may include a second seal 452 disposed along the inner periphery of the flow portion 4231. The second seal 452 may be disposed between the roller and the inner periphery of the flow portion 4231. Furthermore, the second seal 452 may be configured to contact the entire back surface 220 of the roller and the rear plate 420. The second seal 452 is capable of preventing hot air moving along the flow portion 4231 from leaking towards the mounting portion 425.

[0263] As the roller 200 rotates during the operation of the garment handling device, continuous friction is applied to the sealing portion 450 due to the back surface 220 of the roller. Therefore, the sealing portion 450 is preferably made of a material that can seal the area between the back surface 220 of the roller and the flow portion 4231 without performance degradation due to the frictional force and frictional heat generated by rotation.

[0264] The garment processing device of this utility model may further include a circulating fan 950, which is configured to be combined with the circulating pipe 820 to circulate the air inside the drum.

[0265] The circulating fan 950 may further include: an impeller disposed inside the circulating pipe 820; and a fan motor 951 mounted on the impeller and outside the circulating pipe 820 to rotate the impeller.

[0266] The fan motor 951 can be understood as a motor installed behind the circulation pipe 820 and driving the circulation fan 950.

[0267] The fan motor 951 can be separated from the drive motor 510 of the drive unit 500, so that the fan motor 951 can be controlled independently of the drive motor 510.

[0268] As a result, the circulating fan 950 can be controlled independently of the drive unit 500. In other words, the drive unit 500 can repeatedly perform stationary and driven operations separately from the circulating fan 950.

[0269] Reference Figure 5b The reducer 600 can be supported by the rear plate 420, and the drive unit 500 can be combined with the reducer 600. That is, the rear plate 420 can be configured to support both the reducer 600 and the drive unit 500.

[0270] A drive unit 500 that provides rotational power and a reducer 600 that reduces the power of the motor and transmits it to the roller can be provided behind the rear plate 420.

[0271] The speed reducer 600 can be disposed in the rear plate 420 such that it is located inside the pipe section 423. The speed reducer 600 can be located radially inside the flow section 4231 to prevent interference with the flow section 4231.

[0272] The hot air moving along the flow section 4231 may damage the gear mechanism inside the reducer 600. Therefore, the flow section 4231 and the reducer 600 can be configured to be separated by a predetermined distance.

[0273] The reducer 600 can be connected through the rear plate 420. Therefore, the reducer 600 can be connected to the roller located in front of the rear plate 420.

[0274] The motor unit 500 may include: a stator 510 that generates a rotating magnetic field; a rotor 520 that rotates using the stator 510; a drive shaft 530 that rotates using the rotor 520 to rotate the internal structure of the reducer 600; and a washer unit 540 that connects the rotor 520 to the drive shaft 530.

[0275] The stator 510 can be combined with the reducer 600. The stator 510 can be combined with the reducer 600 and spaced apart from the rear plate 420. In this case, the reducer 600 can be located between the roller and the motor section, supporting the roller and the motor section and spaced apart from the rear plate 420. That is, the reducer 600 can become the center supporting the roller and the motor section.

[0276] On the other hand, the stator 510 may include: a body body 511 configured in a ring shape; a fixing rib 512 extending from the inner peripheral surface of the body body 511 and engaging with the stator engagement portion 613 of the reducer; a tooth 514 configured to extend from the outer peripheral surface along the periphery of the body body 511 for winding a coil; and a pole shoe 515 disposed at the free end of the tooth 514 to prevent the coil from disengaging.

[0277] The rotor 520 may include a rotor body 521 configured as a hollow cylinder. Furthermore, the rotor 520 may include a mounting body 522 recessed forward from the back of the rotor body 521. Permanent magnets may be disposed along the inner circumferential surface of the rotor body 521.

[0278] The rotor 520 can be coupled to the drive shaft 530 to transmit rotational power of the rotor 520 to the outside via the drive shaft 530. The drive shaft 530 can be connected to the rotor 520 via a washer portion 540.

[0279] Furthermore, the drive unit 500 may include a washer portion 540 that supports the drive shaft 530. The washer portion 540 may include a washer engagement body 541 that engages with the rotor. The washer engagement body 541 may be configured in a disk shape.

[0280] The washer portion 540 may include a receiving body 542 accommodated in the rotor. The receiving body 542 may be configured to protrude rearward from the washer coupling body 541. The washer portion 540 may include a shaft support hole 543 extending through the center of the receiving body 542. The drive shaft 530 may be inserted into the shaft support hole 543 and supported by the washer portion 540.

[0281] Furthermore, the washer portion 540 may include a washer engagement hole 5412 that penetrates the washer engagement body 541. The mounting body 522 may include a rotor engagement hole 526 located at a position corresponding to the washer engagement hole 5412. That is, the washer portion 540 and the rotor 520 can be engaged with each other via a engagement member that penetrates both the washer engagement hole 5412 and the rotor engagement hole 526. In other words, the washer portion 540 and the rotor 520 can be engaged to rotate together.

[0282] Furthermore, the washer portion 540 may include a washer engagement protrusion 5411 protruding rearward from the washer engagement body 541. The mounting body 522 may include a washer protrusion receiving hole 525 corresponding to the washer engagement protrusion 5411. The washer engagement protrusion 5411 can be inserted into the washer protrusion receiving hole 525 to support the engagement of the washer portion 540 and the rotor 520.

[0283] Furthermore, the rotor 520 may include a rotor mounting hole 524 extending through the center of the mounting body 522. The rotor mounting hole 524 can accommodate the receiving body 542. Thus, the washer portion 540 can rotate together with the drive shaft 530 via the rotor 520, and the connection between the drive shaft 530 and the rotor 520 can be securely supported. Therefore, it has the effect of ensuring the overall durability and reliability of the drive unit 500.

[0284] Figure 6 Another embodiment of the garment handling device of this utility model is shown.

[0285] The clothing processing device of this utility model can also be configured as a dryer with washing function that can also perform a washing process to remove foreign objects from clothing.

[0286] In this case, the garment handling device of the present invention may include: an outer tub 190, which is housed inside the box 100 and stores water; and a roller 200, which is rotatably housed in the outer tub 190 and stores water.

[0287] The garment handling device of this utility model may include: a water supply unit 160, which supplies water to the outer tub 190; and a drainage unit 170, which drains water from the outer tub 190.

[0288] The water supply unit 160 may include: a water supply valve 161, which is coupled to the housing 10 and connected to an external water source to selectively supply water; and a water supply pipe 162, which extends from the water supply valve 161 and transmits water supplied from the external water source. The water supply pipe 162 may be coupled to the outer tub 190, or its end may be coupled to a gasket connecting the front panel 110 and the outer tub 190.

[0289] The drainage section 170 may include: a discharge pipe connected to the lower part of the outer tub 190 for discharging water from the outer tub 190; a drainage pump that provides power to discharge water supplied from the discharge pipe to the outside of the housing 100; and a drainage pipe extending from the drainage pump to the outside of the housing 100 for discharging water.

[0290] On the other hand, the garment processing apparatus of this invention can position the circulation pipe 820 that circulates air through the roller 200 at a position higher than the roller 200. Therefore, the garment processing apparatus of this invention can arrange the circulation pipe 820 without obstruction from the drain section 170.

[0291] The circulation pipe 820 can be placed on and supported by the outer barrel 190.

[0292] In the clothing processing device of this utility model, the drive unit 500 can be combined with and fixed to the outer tub 190.

[0293] The drive unit 500 may include: a stator 510, which is coupled to the rear of the outer barrel 190; a rotor 520, which rotates using the stator 510; and a rotating shaft 530, which connects the rotor 520 and the roller 200.

[0294] The garment processing device of this utility model may further include a circulating fan 950, which is configured to be combined with the circulating pipe 820 to circulate the air inside the drum.

[0295] The circulating fan 950 may further include: an impeller disposed inside the circulating pipe 820; and a fan motor 951 mounted on the impeller and outside the circulating pipe 820 to rotate the impeller.

[0296] The fan motor 951 can be understood as a motor installed behind the circulation pipe 820 and driving the circulation fan 950.

[0297] The fan motor 951 can be separated from the drive motor 510 of the drive unit 500, so that the fan motor 951 can be controlled independently of the drive motor 510.

[0298] As a result, the circulating fan 950 can be controlled independently of the drive unit 500. In other words, the drive unit 500 can repeatedly perform stationary and driven operations separately from the circulating fan 950.

[0299] Figure 7 An embodiment of the internal structure of the garment processing device of this utility model is shown.

[0300] To ensure the volume of air moved or the area of ​​the evaporator and condenser, the circulation pipe 820 may be configured to extend in a "┐" shape on the upper part of the outer casing 190.

[0301] That is, the circulation pipe 820 can extend forward from the upper rear side of the outer barrel 190 and then extend to the upper front side of the outer barrel 190.

[0302] The circulation pipe 820 may include: an inflow pipe 821 extending from the rear to the front of the outer tub 190; a moving pipe 822 extending from the inflow pipe to the other side of the front of the outer tub 190 or a gasket; and an outflow pipe 823 extending downward from the moving pipe and communicating with the interior of the gasket.

[0303] The heat supply unit 900 can be disposed on the upper part of the outer barrel 190.

[0304] The evaporator 910 and the condenser 920 can be disposed inside the moving pipe 822, and the compressor 930 can be mounted on the upper part of the outer barrel 190.

[0305] The compressor 930 can be configured behind the moving pipe 822.

[0306] The movable pipe 822 can extend from the top of the outer barrel 190 to the left and right, and a filter, an evaporator 910 and a condenser 920 can be arranged inside it in sequence.

[0307] The circulating fan 950 may be configured to communicate with the circulating pipe 820.

[0308] The circulating fan 950 may be disposed inside the circulating pipe 820, or may include a housing that connects the moving part and the discharge part.

[0309] The circulating fan 950 is positioned in front of the outer tub 190, thereby evenly distributing the weight behind the outer tub 190, which is coupled to the drive unit 500. The circulating fan 950 can be driven to move air from the inlet to the outlet.

[0310] As a result, the circulation pipe 820 can be omitted from the base 800 in the above embodiment.

[0311] On the other hand, in all embodiments, the garment handling device of the present invention may further include a sensing sensor capable of sensing the degree of drying of the garment in at least either the drum 200 or the front plate 410.

[0312] For example, the sensing sensor can be configured as an electrode sensor, and the intensity of the current sensed when in contact with the clothing varies depending on the moisture content or dryness of the clothing. Therefore, the clothing handling device of this invention can determine the dryness of the clothing using the electrode sensor.

[0313] Furthermore, in all embodiments, the garment handling device of the present invention may also include at least one of the following two sensors: a temperature sensor that senses the temperature of the air expelled from the roller 200; and a refrigerant sensor that senses one or more of the temperature and pressure of the refrigerant exposed from the compressor 930.

[0314] The temperature sensor can be considered as the temperature inside the drum 200, and the temperature sensor can be configured to be installed in the inflow pipe 821 to sense the temperature discharged from the drum 200.

[0315] Therefore, the clothing processing device of this utility model can sense whether the temperature inside the drum 200 has increased and whether the temperature of the refrigerant has increased through the temperature sensor and the refrigerant sensor, and can also calculate the degree of drying of the clothes.

[0316] The electrode sensor, the temperature sensor, and the refrigerant sensor are known technologies and can be configured as sensors used in a typical dryer.

[0317] Furthermore, the garment processing device of this utility model may also include a control unit, which is housed inside the control panel or housing 100 and is used to drive the entire electrical components to perform any drying process.

[0318] The control unit may be composed of a PCB (Printed Circuit Board) panel, which is configured to control the heat supply unit 900, the drive unit 500, and the circulating fan 950 to perform the drying process.

[0319] Figure 8 An embodiment of the control method of the garment handling device of this utility model is shown.

[0320] The garment processing device of this invention can implement any process of the drying procedure. In the garment processing device of this invention, when implementing the aforementioned arbitrary process to perform the drying procedure, the following stages can be executed together: a sensing stage S0, sensing the weight of the garments contained in the drum 200; a heating stage S1, supplying air to the garments and raising the temperature of the air; a constant speed stage S2, continuously supplying heated air to dry the moisture in the garments; a deceleration stage S3, drying a considerable amount of moisture in the garments, causing a significant increase in the temperature inside the drum 200; and a cooling stage S4, completing the drying of the garments and reducing the temperature of the garments and the temperature inside the drum 200 to prevent damage to the garments and safety accidents.

[0321] The sensing stage S0 is a stage in which the roller 200 is rotated and the weight and unbalance of the garment are sensed by the load sensed in the drive unit 500.

[0322] The heating stage S1, the constant speed stage S2, and the deceleration stage S3 are stages in which heated air (hot air) is supplied to the inside of the drum 200 by driving the compressor 930 and the circulating fan 950.

[0323] The cooling stage S4 is a stage in which the temperature inside the drum 200 is reduced by driving the circulating fan 950 and cutting off the drive of the compressor 930.

[0324] Figure 9 The execution was shown Figure 8 The state of the garment handling device when controlled by the method.

[0325] When the heating phase S1 is executed, it can be controlled as follows: start driving the compressor 930 to accelerate it to the target speed (H1, Hz).

[0326] The target speed H1 can also be the maximum performance speed at which the compressor 930 can be driven to its maximum potential. Alternatively, the target speed H1 can be equivalent to the fastest speed at which the compressor 930 is driven throughout the entire drying process. In this case, the target speed H1 can be lower than the maximum performance speed at which the compressor 930 can operate.

[0327] In the heating stage S1, the following control can be implemented: when the driving speed of the compressor 930 reaches the target speed H1, the driving speed of the compressor 930 is maintained until the temperature of the refrigerant discharged from the compressor 930 reaches the target temperature T1.

[0328] For example, when the compressor 930 is driven at the target speed H1 for a first time t1, the temperature of the refrigerant discharged from the compressor 930 can reach the target temperature T1.

[0329] Alternatively, in the heating stage S1, the control can be as follows: when the driving speed of the compressor 930 reaches the target speed H1, the driving speed of the compressor 930 is maintained until the temperature sensed in the circulation pipe 820 reaches the set temperature.

[0330] The set temperature can be the temperature inside the circulation pipe 820 when the temperature of the refrigerant discharged from the compressor reaches the target temperature T1. The set temperature can be sensed in the inflow pipe 821.

[0331] During the heating phase S1, the system can be controlled as follows: the circulating fan 950 is driven to circulate the air inside the drum 200. This heats the refrigerant in the evaporator 910, raising the temperature of the refrigerant discharged from the compressor 930, thereby evaporating moisture from the clothing inside the drum 200.

[0332] Since the clothes are wet after the heating stage S1, the degree of drying will not increase significantly even if some moisture is dried. Therefore, even if hot air is supplied, the temperature inside the drum 200 will not increase significantly or can remain unchanged due to the heat of vaporization of the moisture evaporated from the clothes.

[0333] When the temperature of the refrigerant discharged from the compressor 930 reaches the target temperature T1, the constant speed phase S2 can be executed. The constant speed phase S2 can be equivalent to the phase executed from the time the temperature of the refrigerant reaches the target temperature T1 until the degree of drying of the clothes reaches the set value.

[0334] Since the temperature of the refrigerant remains constant or can rise steadily during the constant speed phase S2, the compressor 930 can be controlled to reduce its drive speed from the target speed H1 to a stable speed H3.

[0335] The stable speed H3 can be set to a speed that maintains the temperature of the hot air supplied to the roller 200, and can be set to a speed lower than the target speed H1.

[0336] In the constant speed phase S2, the speed can also be reduced from the target speed H1 to the stable speed H3 in stages to drive the compressor 930.

[0337] Therefore, in the constant speed stage S2, the power consumption per unit time may be less than that in the heating stage A1.

[0338] During the constant speed phase S2, the circulating fan 950 can be continuously driven without interruption. Therefore, during the constant speed phase S2, hot air can be continuously supplied to the interior of the drum 200.

[0339] Therefore, the moisture contained in the clothing can continuously evaporate. However, in the constant speed phase S2, since the drying degree of the clothing is low and the moisture content is high, moisture can continue to evaporate from the clothing. Therefore, even if the constant speed phase S2 continues, the temperature inside the drum 200 and the temperature of the refrigerant will not rise significantly or can remain constant.

[0340] The constant-speed phase S2 can continue for a second time t2 until the dryness of the garment rises above a specific value D1, or the temperature inside the drum 200 rises above the drying temperature D1. For example, the specific value D1 can correspond to a moisture content of the garment being below 50%. For example, assuming the dryness is 0 when the garment is wet and 100 when fully dried, the specific value D1 can be equivalent to a state of 70.

[0341] Furthermore, the constant speed phase S2 can be performed until the temperature of the refrigerant discharged from the compressor exceeds the target temperature T1. That is, in the constant speed phase S2, the temperature of the refrigerant may become lower than the target temperature T1 due to the reduction of the compressor's drive speed, but the constant speed phase S2 can be performed until it becomes higher than the target temperature T1 again.

[0342] As a result, it can be considered that the constant speed phase S2 is executed at the point in time when the temperature inside the drum 200 rises due to the reduction in the amount of moisture in the clothes being dried and the decrease in the heat of vaporization.

[0343] The drying temperature D1 can be set to a temperature higher than room temperature. For example, it can be set to 45 degrees Celsius or higher.

[0344] The second time T2 can be set to be longer than the first time T1.

[0345] When the degree of drying of the clothes increases, or the temperature inside the drum 200 rises above the drying temperature D1, or the temperature of the refrigerant discharged from the compressor 930 rises again above the target temperature T1, or the degree of drying of the clothes reaches a specific value D1, the deceleration phase S3 can be executed.

[0346] The deceleration phase S3 is a period in which a portion of the clothing has been dried or where a small amount of water has evaporated from the clothing. A third time t3 can be executed until the clothing is completely dried or the drying process can be ensured.

[0347] During the deceleration phase S3, the circulating fan 950 can be controlled to drive continuously, and the compressor 930 can also be controlled to continue driving at the stable speed H3.

[0348] Since the deceleration stage S3 is a state in which the drying of clothes has progressed considerably and continues, the temperature of the refrigerant will continue to rise to the danger temperature T3, and the temperature inside the drum 200 will also rise to the end temperature D2.

[0349] During the deceleration phase S3, the cooling phase S4 can be executed as long as either the danger temperature T3 or the end temperature D2 is reached.

[0350] Furthermore, the deceleration phase S3 can end when the clothes reach the desired dryness level. This desired dryness level can correspond to a state where the dryness is 95% or higher.

[0351] During the cooling stage S4, the compressor 930 can be shut off, and only the circulating fan 950 can be driven. This allows the temperature of the clothes and the inside of the drum 200 to be reduced by supplying air, i.e., unheated air, into the drum 200. During this process, any moisture remaining in the clothes can also be dried.

[0352] The cooling phase S4 can be executed for a fourth time t4 until the temperature inside the garment or the roller 200 reaches a safe temperature or room temperature.

[0353] When the cooling phase S4 ends, the drive of the circulating fan 950 can also be stopped.

[0354] On the other hand, during the period from the sensing phase S0 to the cooling phase S4, the roller 200 can be controlled to rotate.

[0355] In particular, during the heating phase S1, the constant speed phase S2, and the deceleration phase S3, hot air is supplied to the interior of the drum 200, thus controlling the drum 200 to rotate and agitate the clothes, thereby ensuring that the clothes are evenly exposed to the hot air. This prevents damaged or undried portions of the clothes from forming.

[0356] However, in the garment processing apparatus of this invention, considering that the moisture content of the garments changes during the drying process, at least one of the following can be controlled differently in the heating stage S1, the constant speed stage S2, and the deceleration stage S3: the rotational speed, the rotational direction, and the ratio of the rotational time to the stationary time of the roller (hereinafter referred to as the actual rotation rate). This is because if the moisture content of the garments is high, the garments are prone to tangling; if the moisture content of the garments is low, the garments will spread out.

[0357] Furthermore, the garment handling device of this invention can control at least one of the following during the heating stage S1, the constant speed stage S2, and the deceleration stage S3: the rotational speed, the direction of rotation, and the ratio of the rotation time to the stationary time of the roller 200 (hereinafter referred to as the actual motion rate) according to the weight or volume of the garment contained in the roller 200. This is because if the garment is heavy, it is prone to tangling; if the garment is light, it can be easily unfolded inside the roller.

[0358] Furthermore, the garment handling device of this invention can control at least one of the following: the rotational speed, rotational direction, and the ratio of the rotational time to the stationary time of the roller (hereinafter referred to as the actual motion rate) of the roller 200, based on the change in the ratio of the volume to the weight that the roller can accommodate (hereinafter referred to as the bath ratio). This is because the larger the diameter of the roller, the greater the imbalance generated when the roller 200 rotates.

[0359] Hereinafter, embodiments will be described in which at least one of the following is controlled in the drying process: the rotational speed, the rotational direction, and the ratio of the rotational time to the stationary time of the drum 200 (hereinafter referred to as the actual rotation rate) according to different conditions.

[0360] Figure 10 This shows the state of the clothes being put into the drum.

[0361] The clothes can be placed inside the drum 200 before the drying process begins. Even if the amount of clothes L1 is small, they may be in a damp state with a high moisture content.

[0362] Compared to its dry state, in its reduced volume state, the garment L1 is more likely to be positioned close to the bottom surface of the drum 200. If hot air is supplied to the inside of the drum 200 in this state, the area of ​​the garment L1 in contact with the inner wall of the drum will not be exposed to the hot air and will not be dried; only the area exposed to the inside of the drum will be exposed to the hot air and dried.

[0363] To prevent this, the garment handling device of this invention can rotate the drum 200 to agitate the garments or change its configuration during the drying process, thereby guiding the entire surface of the garments to be evenly exposed to hot air.

[0364] Figure 11a , Figure 11b , Figure 11c The internal state of the drum is shown when it is rotated during the drying process.

[0365] Reference Figure 11a To perform the drying process, clothing can be placed inside the drum 200. The clothing is damp and may have a very high moisture content.

[0366] For example, the garment has completed the washing process and its moisture content may be equivalent to 100%.

[0367] Reference Figure 11bWhen the drum 200 is rotated during the sensing phase A0 or the heating phase A1, the configuration of the garment can be changed by moving it inside the drum 200 along the rotation direction of the drum 200, and it can also be agitated. The garment can be evenly exposed to the hot air flowing into the drum 200.

[0368] However, since the garment is wet, it is heavier due to the weight of the moisture compared to when it is dry, so the amount of time it rises within the roller 200 may be very small.

[0369] Furthermore, because the surface of the garment is wet, it is more compressed than when it is dry, and the friction or adhesion becomes very large.

[0370] Reference Figure 11c When the roller 200 rotates continuously while the clothing is wet, the wet clothing may come into contact with each other and stick together as it moves. As a result, when the roller 200 rotates, the clothing is not untied or spread out, but rather becomes more knotted or tangled. The longer the roller 200 rotates, the more severe the knotting or tangling of the clothing becomes.

[0371] Consequently, friction between the garments becomes severe, potentially damaging the garments or causing them to shrink. Furthermore, even during the constant speed phase A2 and deceleration phase A3, knotted and tangled portions of the garments may not be dried, or may worsen wrinkles.

[0372] Figure 12a , Figure 12b The image shows a large quantity of clothing being fed into the drum.

[0373] Reference Figure 12a The drying process can be performed with a large number of clothes L2 being fed into the drum 200. When performing the drying process, the clothes handling device of this invention can rotate the drum 200 so that the surface of the clothes can be evenly exposed to hot air.

[0374] Reference Figure 12b When the drum 200 rotates, the large quantity of clothing can move while changing its position inside the drum 200 or being agitated. When the large quantity of clothing is as wet as a small quantity of clothing, it may also become tangled or more entangled.

[0375] As the roller 200 rotates, the knotted garments may move in the same direction as a ball, potentially concentrating a very strong impact in the direction of movement.

[0376] Thus, when a large amount of damp clothing collides with the door 130, the door 130 may be momentarily pushed forward from the front panel 110, creating a gap g between the door 130 and the opening 111. As a result, when the drying process is performed, since the circulating fan 950 is also driven, moisture inside the drum 200 may leak out through the gap g, potentially causing changes in humidity and temperature at the location of the clothing handling device, or the opposite effect of exposing electrical components such as the control panel 117 located near the front panel 111 to moisture.

[0377] Furthermore, since the damp clothes are heavier than when dried, a greater load may be required to rotate the drum 200. As a result, even if the same clothes are put into the drum 200, the energy required to rotate the drum 200 in a damp state may be much greater than the energy required to rotate the drum 200 in a dry state.

[0378] Furthermore, the garments L1 and L2 may cause strong unbalance inside the roller 200, and may also consume more energy when the roller 200 is rotated, or generate unnecessary vibration or noise in the roller 200.

[0379] Therefore, the clothing handling device of this utility model can set the operating rate of the drive unit 500 to be lower than that when the clothing is wet than when it is drying, or increase the number of times the rotation direction is changed, or set the rotation speed of the drum to be low.

[0380] Therefore, it can prevent damp clothes from rubbing against each other and getting tangled or knotted, and it can also eliminate the off-center nature of knotted or tangled clothes.

[0381] Figure 13a , Figure 13b The method of rotating the drum of the garment handling device of this invention is shown.

[0382] Reference Figure 13a The garment processing device of this utility model can make the drum 200 rotate at a constant speed during the drying process, or make the drum 200 rotate in such a way that the time of rotation of the drum 200 per unit time is longer than the time of stillness.

[0383] Thus, the clothes can rise and fall sequentially inside the drum 200 and be agitated, thereby being evenly exposed to the hot air introduced into the drum 200 and dried.

[0384] In this invention, when the roller 200 is rotated at a constant speed or continuously in one direction, it may be limited to situations where the drying degree of the clothes is high or the weight of the clothes is less than a reference value.

[0385] For example, the reference value may be equivalent to half of the maximum capacity weight that the garment processing device of this invention can hold to perform the drying process.

[0386] The action of making the roller 200 rotate at a constant speed can be defined as a normal action.

[0387] Reference Figure 13b The garment processing device of this utility model can make the roller 200 rotate at a reduced rotational rate.

[0388] For example, the garment handling device of this invention can make the roller 200 rotate at a rate of less than 50% of the actual rotation of the roller 200.

[0389] In the garment processing device of this utility model, when the moisture content of the garment is high and the drying degree is low, or when the weight of the garment is greater than a reference value, the roller 200 can be rotated at a reduced rotational rate.

[0390] As a result, the garment handling device of this invention can prevent the garment from knotting or tangling by minimizing the rotation of the roller 200 when the knotting or tangling of the garment may worsen.

[0391] Furthermore, the clothing processing device of this invention can save energy by minimizing the rotation of the roller 200 when the clothing becomes heavy due to absorbing water.

[0392] In the garment handling apparatus of this invention, when the roller 200 is rotated at a reduced operating rate, the roller 200 can be rotated such that the time the roller is stationary is longer than the time the roller rotates. For example, when the roller 200 is rotated intermittently and discontinuously, the operating rate of the roller 200 can be less than 50%.

[0393] The action of the roller 200 rotating in a repetitive manner of stationary and rotating states can be defined as a protective action. Executing the protective action means controlling the rotation of the roller, and therefore can also be defined as rotation control.

[0394] The clothing handling device of this utility model, through the aforementioned protective action, can eliminate the phenomenon of moisture flowing out between the door 130 and the opening 111, as well as the tangling and knotting of clothing, and can also reduce the power consumption of the drive unit 500.

[0395] Figure 14 An embodiment of a protective action applicable in the drying process of the garment handling apparatus of this invention is shown.

[0396] Typically, clothes are dried during the drying process, so the moisture content is highest in the heating stage S1 and lowest in the deceleration stage S2.

[0397] When the clothing is damp, the protective action prevents tangling and knotting while reducing the load on the drive unit 500. However, if the clothing is dry, it delays the uniform drying process, potentially causing a longer drying time. Therefore, it may be necessary to reduce or omit the protective action.

[0398] With this in mind, the garment handling device of this invention can drive the roller 200 with a protective action at least during the heating stage S1.

[0399] The heating stage S1 is the initial state of the drying process. Even if part of the clothes are dried in the heating stage S1, the moisture content of the clothes can only be maintained at a high level compared with the constant speed stage S2 and the deceleration stage S3.

[0400] Therefore, the garment processing device of this invention can be controlled such that, in the initial stage of the drying process, such as the heating stage S1, the continuous stationary time of the drum is longer than the continuous rotation time.

[0401] On the other hand, the constant speed phase S2 and the deceleration phase S3 represent the progress of the drying process compared to the heating phase S1. Therefore, even if the drum 200 rotates at the same speed, the degree of knotting or tangling of the clothes may be lower than in the heating phase S1. Considering this, the garment handling device of this invention can strengthen the protective action in the heating phase S1 compared to the constant speed phase S2 and the deceleration phase S3. For example, the garment handling device of this invention can strengthen the protective action in the heating phase S1 and weaken or omit the protective action in the constant speed phase S2 and the deceleration phase S3. Since the heating phase S1 is the initial stage of the drying process, and the deceleration phase S3 corresponds to the final stage of the drying process, the garment handling device of this invention can strengthen the protective action in the initial stage of the drying process compared to the final stage.

[0402] It can be that the protection action is strengthened to reduce the actual rotation rate of the roller 200, the protection action is weakened to increase the actual rotation rate of the roller 200, or the protection action is omitted to drive in normal operation.

[0403] In summary, the garment processing device of this utility model can be controlled to rotate the drum 200 at a lower rate (ratio of rotation time to stationary time) than at the end of the drying process when the internal temperature is below the reference value, during the initial stage of the drying process.

[0404] Specifically, the garment processing device of this utility model can be controlled such that, in the initial stage of the drying process when the internal temperature of the circulating pipe is below the set temperature, the drum 200 rotates at a lower rate than in the final stage of the drying process when the internal temperature of the circulating pipe is above the set temperature.

[0405] The heating stage S1 is the range in which the driving speed of the compressor 930 accelerates to its maximum speed and remains thereafter. Therefore, the clothing processing device of this utility model can be controlled such that, in the initial stage of the drying process when the driving speed hz of the compressor is driven to a value above or at its maximum value, the drum 200 rotates at a lower rate than in the final stage of the drying process when the driving speed hz of the compressor decreases to below the set value.

[0406] The garment processing device of this invention can set the actual rotation rate of the drum 200 to less than 50% in the early stage of the drying process. That is, the drum 200 can be controlled to rotate in the heating stage S1 in such a way that the static heating time ta is longer than the rotating heating time TA.

[0407] For example, the heating rotation time TA can be equivalent to 6 seconds, and the heating still time ta can be equivalent to 19 seconds.

[0408] The garment handling device of this invention can set the rotation rate of the drum 200 to 50% or more at the end of the drying process. This ensures sufficient rotation time of the drum 200, allowing the garments to be evenly exposed to hot air, thereby improving drying efficiency and preventing drying delays.

[0409] That is, the roller 200 can be controlled to rotate in the deceleration phase S3 in such a way that the rotation time TC of the rotational deceleration is longer than the stationary time tc of the stationary deceleration.

[0410] The deceleration stagnation time tc can be set to be shorter than the heating stagnation time ta.

[0411] As a result, in the heating phase S1, when the roller is stationary and then rotates again, the roller 200 can remain stationary for a longer period than in the deceleration phase S3.

[0412] Furthermore, the deceleration rotation time TC can be set to be longer than the heating rotation time TA. As a result, in the heating phase S1, the roller 200 can rotate in a manner where the time between the roller coming to a standstill and the roller rotating again is shorter than in the deceleration phase S3.

[0413] In summary, the roller 200 can be controlled to rotate at a lower rate of motion during the heating phase S1 than during the deceleration phase S3. In other words, during the heating phase S1, the roller 200 can be made to rotate at a lower rate of motion than during the deceleration phase S3.

[0414] The constant-speed stage S2 is an intermediate stage in the drying process, corresponding to a stage where the degree of dryness of the clothes is higher than that of the heating stage S1 but lower than that of the deceleration stage S3. Therefore, in the constant-speed stage S2, the degree of knotting of the clothes may be less than that of the heating stage S1, but greater than that of the deceleration stage S3.

[0415] With this in mind, the roller 200 can be controlled to rotate at a lower rate during the constant speed phase S2 than during the deceleration phase S3.

[0416] The roller 200 can be controlled to rotate at a lower rate of motion during the heating phase S1 than during the constant speed phase S2. In other words, during the heating phase S1, the roller 200 can be rotated at a lower rate of motion than during the constant speed phase S2.

[0417] In the constant speed phase S2, the constant speed rotation time TB of the roller can be set to be the same as or longer than the constant speed still time tb of the roller.

[0418] Furthermore, the constant speed rotation time TB can be set to be longer than the heating rotation time TA, and the constant speed stationary time tb can be set to be shorter than the heating stationary time tb.

[0419] That is, in the constant speed stage S2, the actual rotation rate of the roller can be set to 50% or more.

[0420] As a result, the drum can remain stationary for a longer period of time during the heating phase S1 than during the constant speed phase S2.

[0421] Of course, unlike the illustration, the constant speed stage S2 is also a state where the clothes are more humid than in the deceleration stage S3, so the roller 200 can rotate at the same rate of rotation as in the heating stage S1. Furthermore, in the constant speed stage S2, the rate of rotation of the roller can be set to 50% or less.

[0422] On the other hand, the drum 200 can be controlled to rotate at the same speed throughout the entire drying process. That is, the drum 200 can rotate at the same speed during the heating rotation time TA, the constant speed rotation time TB, and the deceleration rotation time TC.

[0423] As a result, the clothing processing device of this invention can set the actual rotation rate of the roller to be lower than that of the deceleration stage S3 in at least one of the heating stage S1 and the constant speed stage S2 when the clothing is wet.

[0424] Therefore, the clothing processing device of this invention can eliminate the tangling and knotting of clothing, prevent wrinkles, and create an environment that can evenly dry the clothing, thereby shortening the execution time of the drying process.

[0425] Furthermore, the clothing handling device of this invention can also reduce the impact amount applied to the door 130 when the clothing comes into contact with the door 130, thereby preventing the moisture inside the roller 200 from flowing out to the outside.

[0426] Furthermore, the clothing handling device of this invention can eliminate eccentricity by preventing the clothing from tangling, thereby greatly saving the load on the drive unit 500 and the power consumption of the compressor 930 and the circulating fan 950.

[0427] Figure 15 The diagram shows the power consumption variation based on the actual operating rate of the drum when drying a large quantity of clothes during the heating phase.

[0428] In the clothing processing device of this utility model, when a large amount of clothing L2 is dried in the heating stage S1, the rotation and stillness of the roller 200 are repeated to prevent the clothing from tangling or knotting.

[0429] The large quantity of clothing L2 can correspond to the maximum weight of clothing that can be accommodated in the roller 200.

[0430] Reference Figure 15 In the clothing handling apparatus of this invention, when the drum 200 containing the large amount of clothing L2 is rotated at a rate of 80% or more during the heating stage S1, the effect of preventing clothing from knotting or tangling decreases, and the power consumption also increases to above a set value. This is because, since the large amount of clothing L2 is in a state of absorbing moisture, it is heavier than when it is dried, and therefore the drive unit 500 requires too much energy to rotate it.

[0431] Furthermore, in the clothing processing apparatus of this invention, when the drum 200 containing the large amount of clothing L2 is rotated at a rate of less than 20% during the heating stage S1, although it can prevent the clothing from tangling or getting tangled, the power consumption is higher compared to rotating at a rate of more than 20%. Moreover, it can be seen that when the drum 200 is rotated at a rate of less than 13%, the power consumption exceeds the set value. This is because, since the clothing cannot be agitated inside the drum 200, the drying of the clothing cannot be fully performed, and therefore sufficient heat cannot be supplied to the evaporator 910, thus requiring a long time to drive the compressor 930 at maximum speed and maximum temperature. That is, if the rate of rotation is too low, the duration of the heating stage S1 will be longer, thus increasing power consumption.

[0432] Furthermore, in the clothing processing device of this invention, when the roller 200 containing the large amount of clothing L2 is rotated at a rate of 20% to 30% during the heating stage S1, the power consumption is minimal.

[0433] In summary, when a large amount of clothing L2 is fed into the roller 200, the clothing handling device of this invention can control the roller 200 to rotate at a rate ranging from 13% to 80% during the heating stage S1. This reduces clothing tangling and knotting, saves electricity, and thus conserves energy.

[0434] Most preferably, when a large amount of clothing L2 is fed into the roller 200, the clothing handling device of this invention can control the roller 200 to rotate at a rate of 20% to 30% during the heating stage S1. This ensures optimal performance with minimal power consumption while maximizing the prevention of clothing tangling and knotting.

[0435] Figure 16 The diagram shows the power consumption variation based on the actual operating rate of the drum when drying a large volume of clothes in the constant speed phase.

[0436] Although the constant-speed phase S2 is executed after the heating phase S1, the large quantity of clothing L2 contained in the drum 200 remains in a state of very high moisture content. That is, during the constant-speed phase S2, due to the heat of vaporization of the moisture evaporating from the clothing, even if hot air is supplied to the inside of the drum 200, the temperature cannot be raised significantly. Therefore, it can be seen that the moisture content of the large quantity of clothing L2 inside the drum 200 remains high during the constant-speed phase S2. Consequently, if the drum 200 is rotated continuously without interruption or at a high rotation rate during the constant-speed phase S2, the clothing may become knotted or tangled at any time.

[0437] Reference Figure 16It is understood that in the clothing processing device of this invention, when the roller 200 containing the large amount of clothing L2 is rotated at a rate of 80% or more during the constant speed stage S2, the power consumption is higher compared to when it is rotated at a rate of less than 80%. This is because the large amount of clothing L2 is still in a state of absorbing moisture and is therefore very heavy; therefore, the drive unit 500 requires a large amount of energy to make it rotate continuously.

[0438] Furthermore, in the garment processing apparatus of this invention, when the drum 200 containing the large amount of garments L2 is rotated at a rate of less than 20% during the constant speed phase S2, the power consumption suddenly increases compared to when the rate of rotation is low. Specifically, it can be confirmed that when the drum rotates at a rate of less than 16%, the power consumption remains similar to that when it rotates at a rate of more than 80%. This is because, since the garments cannot be sufficiently agitated inside the drum 200, the drying of the garments cannot be completely performed. Therefore, the temperature inside the drum 200 cannot rise sufficiently, causing the undried garments adhering to the inner wall of the drum and not exposed to the hot air to enter the deceleration zone at a slower speed through contact with the electrode sensor.

[0439] Furthermore, it is known that in the clothing processing device of this utility model, when the roller 200 containing the large amount of clothing L2 is rotated at a rate of 20% to 30% during the constant speed stage S2, the power consumption is minimized.

[0440] As a result, in the garment handling device of this invention, when a large amount of garments L2 are fed into the roller 200, the roller 200 can be controlled to rotate at a rate of 16% to 80% during the constant speed stage S2. This reduces the tangling and knotting of garments and saves electricity, thus conserving energy.

[0441] Most preferably, in the garment handling device of this invention, when a large amount of garments L2 are fed into the roller 200, the roller 200 can be controlled to rotate at a rate of 20% to 30% during the constant speed phase S2. This ensures optimal performance with minimal power consumption while maximizing the prevention of garment tangling and knotting.

[0442] Figure 17 The diagram shows the power consumption variation based on the drum's operating rate when drying a small amount of clothing during the heating phase.

[0443] In the clothing processing device of this utility model, when a small amount of clothing L1 is dried in the heating stage S1, the rotation and stillness of the roller 200 are repeated to prevent the clothing from tangling or knotting.

[0444] The small amount of clothing L1 can correspond to a weight of less than 1 / 2 of the maximum weight of clothing that can be contained in the roller 200.

[0445] Reference Figure 17 It can be seen that in the clothing processing device of this utility model, during the heating stage S1, even if a small amount of clothing L1 is put into the drum 200, the power consumption increases as the actual operation rate increases from 30% to 100%, just like when a large amount of clothing L2 is put into the drum. Conversely, the power consumption increases as the actual operation rate decreases from 20% to 0%.

[0446] Furthermore, it is known that during the heating stage S1, even when a small amount of clothing L1 is placed in the drum 200, the power consumption is lowest when the drum rotates at a rate of 20% to 30%, similar to when a large amount of clothing L2 is placed in the drum.

[0447] This can be understood as follows: when the drum rotates at a high rate regardless of the amount of clothing, the weight inside the drum 200 increases due to the weight of the moisture contained in the clothing, requiring a large amount of energy to drive the drive unit 500. When the drum rotates at a low rate, the clothing is not dried evenly, and the time to enter the constant speed stage S2 is slower. Therefore, the driving time of the compressor 930 and the circulating fan 950 increases, thus requiring a large amount of energy.

[0448] Therefore, in the clothing processing device of this utility model, the roller 200 is rotated at a rate of 20% to 80% during the heating stage S1, which can prevent clothing from tangling or knotting, save power consumption, and enable the roller 200 to rotate at an optimal rate of 20% to 30%.

[0449] Figure 18 The diagram shows the power consumption variation based on the actual operating rate of the drum when drying a small amount of clothes in the constant speed phase.

[0450] It can be confirmed that in the constant speed stage S2, when the amount of clothing is small (L1), the change in power consumption based on the actual movement rate is different from that of a large amount of clothing (L2).

[0451] This can be understood as follows: when there are a small number of clothes (L1), unlike when there are a large number of clothes (L2), the clothes can be dried quite a bit through the heating stage (S1) alone, thus exhibiting the characteristics of clothes in a dry state rather than the characteristics of clothes in a damp state.

[0452] However, it can be confirmed that in the constant speed stage S2, even when the amount of clothing is small (L1), the power consumption is lowest when the roller 200 is rotated at a rate of 20-30%.

[0453] Therefore, considering power consumption, the clothing processing device of this invention can also operate at a rate of 20% to 30% in the constant speed stage S2 when there is a small amount of clothing L1.

[0454] Alternatively, taking into account both preventing drying delays and ensuring the drying performance of the clothes, the clothes handling device of this invention can also rotate the drum 200 at a rate higher than 30% in the constant speed stage S2 when there are only a few clothes L1. For example, the drum 200 can be rotated at a rate in the range of 80-100% or 30-70%.

[0455] Figure 19a , Figure 19b , Figure 19c An embodiment of the garment handling device of this invention is shown, in which the drum rotates while changing its rotation direction.

[0456] The clothing processing device of this invention can be controlled to change the rotation direction of the drum at any time during the drying process to eliminate the knotting or tangling of clothing.

[0457] That is, the clothing processing device of this invention can guide the roller to change its rotation direction to untangle or untangle clothing.

[0458] Reference Figure 19a The roller 200 can be rotated in one direction while the clothes rise from the bottom to the top of the roller 200, and the clothes are exposed to the hot air flowing into the roller 200.

[0459] The roller 200 can be guided to rotate continuously in one direction while the clothes inside the roller 200 repeatedly and to the maximum extent possible fall off the inner wall of the roller 200. The clothes are exposed to the hot air introduced into the roller 200 by rising and falling, thereby performing drying.

[0460] For example, the garment can rise to a position higher than the rotation center O of the roller 200 and then fall downwards towards the bottom of the roller 200.

[0461] However, when clothing is damp and has absorbed moisture, its weight and strong adhesion prevent it from moving sufficiently upwards along the rotation direction of the roller 200, potentially causing it to roll down to the bottom of the roller 200. During this process, the clothing may knot or entangle itself, and may also become entangled or knotted with other clothing upon contact.

[0462] Reference Figure 19b The rotation of the roller 200 can be interrupted after it has been rotated in one direction.

[0463] The roller 200 can be temporarily interrupted.

[0464] Alternatively, the roller 200 can be interrupted for a certain period of time. Even when the rotation of the roller 200 is interrupted, hot air can still be supplied to its interior. During this process, the clothes can be dried to a certain extent. The interruption of the roller 200's stillness for a certain period can be achieved without exacerbating the tangling or knotting of the clothes.

[0465] Reference Figure 19c Then, the roller 200 can restart its rotation. At this time, the roller 200 can rotate in a direction different from its initial rotation direction. That is, the roller 200 can rotate in the opposite direction, i.e., another direction. As a result, the clothing can move in the opposite direction to when the roller 200 was rotating in one direction, thus rising and falling.

[0466] During this process, tangled or knotted clothing can begin to be untangled, and as the rotation of the roller 200 is repeated, any eccentricity inside the roller 200 can also be eliminated.

[0467] The clothing processing device of this invention can repeat this process during the drying process.

[0468] On the other hand, during any drying process, except in the sensing phase S0, the garment handling device of this invention can ensure that the garments rotate at a speed that rises to a position higher than the rotation center O of the drum 200. That is, since the drum 200 rotates at a set rate, it can rotate at a fast speed that allows the garments to rise sufficiently. In cases where the garments are subjected to excessive impact, repeated tangling, knotting, or friction, the drum 200 can be brought to a standstill to eliminate such problems.

[0469] Figure 20 It shows that it is executed together with the control of the actual rate. Figure 19a , Figure 19b , Figure 19c An example of a control method.

[0470] In the clothing handling device of this utility model, in order to prevent the damp clothes from getting tangled and knotted during the drying process, causing wrinkles or damage to the clothes themselves, or to push the door 130, or to increase the load on the drive unit 500, or to cause unbalance in the roller 200, the method of setting the actual rate in the drive unit 500 to drive the drive unit 500 and the method of changing the rotation direction of the roller can all be applied.

[0471] When the clothing handling device of this utility model drives the drive unit 500 by setting the actual motion rate, it can take into account the situation where the roller 200 is stationary and control it to change the rotation direction of the roller when the roller 200 is rotated again.

[0472] In the clothing handling device of this utility model, even if the roller 200 is rotated in a way that reduces the actual operation rate of the drive unit 500, a certain degree of entanglement and knotting will still occur in the damp clothing. When there is a large amount of clothing, even if the continuous rotation time of the roller 200 is short, the entanglement and knotting of the clothing may be aggravated. Taking this into consideration, the roller 200 can be rotated by changing its rotation direction at least once in each interval where the roller 200 is stationary and then rotates again.

[0473] For example, roller 200 can rotate clockwise for a rotation time T.

[0474] Afterward, the roller 200 may remain stationary for a period of time t, which is longer than the rotation time T during which the roller 200 rotates according to the actual rotation rate set in the drive unit 500.

[0475] The roller 200 can rotate again for a rotation time T that is less than the rest time t. During this process, the roller 200 can rotate counterclockwise for a rotation time T.

[0476] After that, it can be brought to a standstill again for a standstill time t.

[0477] When the roller 200 rotates again, it can rotate clockwise again for a rotation time T.

[0478] The aforementioned process can be repeated during the drying process.

[0479] As a result, when the roller 200 rotates at the actual rate set in the drive unit 500 during the heating stage S1, constant speed stage S2, and deceleration stage S3, the garment handling device of this utility model can control the roller 200 to change its rotation direction at least once during all processes of rotating the roller 200 again after it has come to a standstill.

[0480] Figure 21 An embodiment of the drum rotation control method of this invention applicable to the drying process is shown.

[0481] Figure 21 It can be equivalent to in Figure 14 The control method now includes the option to handle changes in the direction of drum rotation.

[0482] When the drying process is performed, the drum 200 does not rotate continuously, but is set to rotate and be interrupted repeatedly. The rotation direction of the drum 200 can be controlled to change when it stops and then rotates again. However, the number of times the rotation direction of the drum is changed can be set to be less than the number of times the drum 200 repeats the stopping and rotating process.

[0483] For example, when the moisture content of the clothes is high in a damp state, the tangling and knotting of the clothes can be eliminated by increasing the number of times the rotation direction of the roller 200 is changed, thereby improving the eccentricity inside the roller 200.

[0484] However, if the rotation direction of the roller 200 is changed, the clothes will move in a direction different from their original rotation direction inside the roller 200, thereby increasing friction between the clothes. With this in mind, when the clothes are dry or have low moisture content, the time or condition of friction between the clothes can be reduced by maintaining the rotation direction of the roller 200 for a longer period, thus preventing the clothes from pilling or being damaged.

[0485] The garments are initially damp during the drying process, but the degree of dryness gradually increases as the drying process progresses.

[0486] Therefore, in the initial stage of the drying process, the garment handling device of this invention can focus on preventing clothes from knotting or tangling by frequently changing the rotation direction of the drum. However, as the drying process progresses, it can prevent clothes from pilling by keeping the rotation direction of the drum constant or by making the drum rotate continuously, while focusing on the rapid drying of clothes rather than on preventing clothes from knotting or tangling.

[0487] In summary, the drum 200 can be controlled to rotate more frequently in the initial stage of the drying process when the internal temperature is below the reference value than in the later stage of the drying process when the internal temperature is above the reference value.

[0488] Specifically, the roller 200 can be controlled to rotate more frequently during the initial stage of the drying process when the temperature inside the circulation pipe is below the set temperature, compared to the later stage of the drying process when the temperature inside the circulation pipe is above the set temperature.

[0489] The drum 200 can be controlled to rotate more frequently in the initial stage of the drying process when the compressor's drive speed hz is driven to the target speed H1 than in the later stage of the drying process when the compressor's drive speed hz is reduced to below the target speed H1.

[0490] The initial stage of the drying process and the stage where the compressor drives the compressor to the target speed H1 are the heating stage. The remaining stages can be the constant speed stage S2 and the deceleration stage S3.

[0491] Therefore, the roller 200 can be controlled to rotate in the heating phase S1 in a manner that changes its rotation direction more often than in the constant speed phase S2 or the deceleration phase S3.

[0492] The heating phase S1 can be configured to change the rotation direction of the roller 200 more times than the deceleration phase S3.

[0493] The heating phase S1 can be set to change the rotation direction more times than the constant speed phase S2.

[0494] In the heating stage S1, the frequency of changing the rotation direction after the rotational heating rotation time TA, after the static heating static time ta, and after the rotational heating rotation time TA again can be set to be more than the frequency of changing the rotation direction in the constant speed stage S2 and the deceleration stage S3.

[0495] For example, in the heating stage S1, the rotation direction can be controlled to change whenever there is a rotational heating time TA, a static heating time ta, or another rotational heating time TA. This prevents clothing from knotting and tangling, and eliminates the occurrence of clothing knotting and tangling.

[0496] The heating rotation time TA and the heating stationary time ta can be set to be the same as those described in the embodiments above.

[0497] In the constant speed phase S2, the rotation direction of the roller 200 can be changed during the next constant speed rotation time TB after repeating the action of rotating at a constant speed for ...

[0498] The constant speed rotation time TB and the constant speed stationary time tb can be set to be the same as those described in the above embodiments.

[0499] In the deceleration phase S3, the rotation direction of the roller 200 can be changed at the next deceleration phase S3 after repeating the action of rotating for a deceleration time TC followed by a stationary deceleration time tc four or five times. Alternatively, in the deceleration phase S3, the rotation direction of the roller can remain completely unchanged, or the roller can rotate continuously without stopping. Thus, in the deceleration phase S3, both pilling of the clothes can be prevented, and the drying of the clothes can be more focused.

[0500] The deceleration rotation time TC and the deceleration stationary time tc can be set to be the same as those described in the above embodiment.

[0501] That is, when the clothing processing device of this utility model performs any drying process, it can selectively change the rotation direction of the drum when the set motion rate of the drum 200 is repeatedly rotated and stationary.

[0502] Figure 22 The control method of the garment handling device of this invention is shown, and the energy-saving effect varies depending on the progress of the drying process.

[0503] In the garment processing apparatus of this invention, when the garment absorbs moisture and becomes heavier, the roller 200 can be rotated at a reduced operating rate of the drive unit 500; when the garment is dried and its weight becomes lighter, the roller 200 can be rotated at an increased operating rate of the drive unit 500. This prevents the garment from knotting, tangling, or wrinkling, and also optimizes the drying process.

[0504] The protective action of the garment handling device of this utility model can be regarded as including at least one of the following: the action of repeatedly rotating and stopping the roller 200 according to the actual rate, and the action of changing the rotation direction of the roller 200.

[0505] The normal operation of the garment processing device of this utility model is the same as the driving of the drum, which is equivalent to the action of making the drum rotate continuously without stopping. Since it rotates continuously, the rotation direction of the drum can remain unchanged.

[0506] In the garment processing device of this invention, compared with the existing garment processing device that makes the drum rotate only in normal operation, the power consumption can be reduced by 6.5% when performing the same drying process.

[0507] Specifically, the clothing processing device of this invention can reduce power consumption by 16.4% during the heating stage S1.

[0508] This can be understood as an effect caused by the following: during the heating stage S1, the drive unit 500 does not continuously rotate the drum 200 containing clothes that have become heavier due to absorbing moisture, thus ensuring the time during which the drive unit 500 is stationary.

[0509] In particular, this effect can be maximized when the drive unit 500 is driven within the range of 20 to 30% of its actual operating rate.

[0510] The clothing processing device of this invention can reduce power consumption by 6.8% during the constant speed stage S2.

[0511] This can be understood as an effect caused by the following: during the constant speed stage S2, the drive unit 500 does not continuously rotate the drum 200 containing heavy clothes that have absorbed moisture, thus ensuring the time during which the drive unit 500 is stationary.

[0512] In particular, this effect can be maximized when the drive unit 500 is driven within the range of 20 to 30% of its actual operating rate.

[0513] However, the clothing handling device of this invention can increase power consumption by 6.8% during the deceleration phase S3.

[0514] This can be understood as an effect caused by the following: the drying time is slightly extended because the drum 200 is kept stationary during the deceleration phase according to the actual rate set in the drive unit 500.

[0515] However, although energy consumption is increased in the deceleration phase S3, energy is reduced throughout the drying process. Therefore, it is meaningful to apply protective actions in the deceleration phase S3, as it can prevent clothes from knotting, tangling, and wrinkling and prevent the side effects caused therefrom.

[0516] Of course, the garment handling device of this utility model can also drive the roller 200 in normal operation during the deceleration stage S3.

[0517] Figure 23 The energy-saving effect of each component when the control method of the clothing handling device of this utility model is applied is shown.

[0518] In the garment handling device of this invention, when the control method of applying the protective action is used, the power consumption of the drive unit 500 can be reduced by 39%.

[0519] This confirms that not only can overload of the drive unit 500 be prevented, but also the lifespan of the drive unit 500 or the durability of the entire garment processing device can be guaranteed.

[0520] Of course, with the drive unit 500 coming to a standstill, the completion of drying clothes may be delayed, and therefore the power consumption of the compressor 930 may increase by 4.3% and the power consumption of the fan 950 may increase by 9.5%.

[0521] However, since the power reduction of the drive unit 500 is sufficient to compensate for it, it can be confirmed that the clothing handling apparatus of this disclosure can save 6.5% of energy compared to performing the drying process in normal operation.

[0522] Figure 24 The diagram illustrates a situation where the energy level improves when the control method of the garment handling device of this invention is applied.

[0523] Typically, the energy level applicable in a dryer such as the garment handling apparatus of this invention is calculated as an energy consumption level publicly set based on the power consumption (wh) generated when drying once according to the standard drying capacity (kg).

[0524] Good drying performance is achieved when drying a large amount of clothing with the same power consumption, so a lower energy rating is more advantageous.

[0525] Compared to existing garment handling devices that are driven solely by normal operation, the garment handling device of this invention has a lower energy level, thus confirming its superiority.

[0526] Figure 25 This illustrates a situation where the sealing effect of a door is improved when the control method of the garment handling device of this invention is applied.

[0527] It can be confirmed that, compared with existing garment handling devices, the garment handling device of this utility model reduces the displacement of the door 130 from the opening 111 by utilizing a control method of protective action.

[0528] The fact that the displacement of the door 130 is less than that of existing garment handling devices confirms the following effect: When performing the drying process, the garment handling device of this invention applies a high rate of motion when the drum 200 rotates, thus preventing clothes from getting tangled or wrapped, and thereby avoiding the concentration of force applied to the door 130 when the clothes move in the drum 200.

[0529] It can be confirmed that, regardless of the humidity sensed along any part of the periphery of the door 130, the change in humidity around the door 130 of the clothing handling device of this invention is naturally less than that of existing clothing handling devices.

[0530] Figure 26 The applicability of the control method of the garment handling device of this invention is shown in different embodiments depending on the ratio of the maximum volume of the drum to the maximum weight it can hold.

[0531] In the garment handling device of this invention, the control method of protective action can be maximized as the amount or weight of garments put into the drum 200 increases.

[0532] The control method for applying the protective action may be effective depending on how close the amount of clothing put into the drum 200 is to the maximum amount of clothing that the drum 200 can hold, or how close it is to the maximum amount of clothing that the drive unit 500 can perform the drying process.

[0533] When the weight of the clothes actually put in is 40% of the maximum weight that can be accommodated in the drum 200 to allow the drying process to be carried out, the load required by the drive unit 500 to rotate the drum 200 may not be much. Furthermore, since the interior of the drum 200 ensures sufficient space for the clothes to move, even if the drum 200 rotates continuously for a long time, the clothes will not become knotted or tangled, or the degree of tangling will be very slight.

[0534] Furthermore, as the diameter of the roller 200 increases, the amount of clothing contained in the roller 200 also increases. However, even with the same amount of clothing, the eccentric force applied to the drive unit 500 is stronger than when the diameter is smaller, resulting in a greater load when the drive unit 500 is driven.

[0535] Taking this into consideration, in the control method of the garment handling device of this utility model, the smaller the ratio of the maximum accommodating volume to the maximum weight that the roller 200 can accommodate (hereinafter referred to as the bath ratio), the more the power consumption of the drive unit 500 can be significantly reduced when the protective action of the garment handling device of this utility model is applied.

[0536] The liquor ratio varies depending on the design conditions of the drive unit and the drum of the garment processing device of this utility model. However, for ease of explanation, the liquor ratio of the drum is defined below.

[0537] In other words, such as Figure 26 As shown, in the garment handling apparatus of this invention, assuming the diameter expands from D1 to D2, the weight of garments that can be accommodated increases further relative to the increase in volume, which may lead to a smaller liquor ratio. If the accommodating volume increases, it may accommodate a correspondingly larger amount of wet garments, thus causing the liquor ratio of the drum to decrease.

[0538] The smaller the liquor ratio, the more the load applied to the drive unit 500 will increase, and the more clothes are put in, the more the clothes will become tangled and knotted.

[0539] In the garment handling device of this invention, when the liquor ratio is 13 or less, more garments are put into the drum compared to when the liquor ratio is 13 or more. As a result, the load required to drive the drive unit 500 increases, and more garments become knotted or tangled.

[0540] Therefore, the control method for applying protective actions in the garment handling device of this utility model can be effective when the bath ratio of the drum is set to 13 or less.

[0541] Furthermore, in the garment treatment device of this invention, when the liquor ratio is set to 10.5 or less, the effect of the applicable protective action can be maximized.

[0542] For example, if the diameter of the drum 200 is 27 inches, which is larger than that of a typical dryer, the maximum laundry capacity (maximum drying load) can be set to 22 kg, and in this case, the bath ratio can be set to 10.5 or less.

[0543] With the diameter and length of the roller 200 designed in this way, the control method for the protective action of the garment handling device of this utility model can be directly applied.

[0544] Conversely, when the bath ratio of the roller 200 of the garment handling device of this invention is 13 or higher, a general control method using normal operation can be applied instead of the control method using the protective operation.

[0545] The conditions for the control method of the garment handling device of this utility model, which includes protection actions of at least one of the actual rate and the change of rotation direction, can also be set as the bath ratio of the drum.

[0546] Figure 27a , Figure 27b The control method of the garment handling device according to the present invention is shown in different embodiments depending on the garment capacity.

[0547] Reference Figure 27a A small amount of clothing L1 can be placed in the drum 200, as per [reference]. Figure 27b A large amount of clothing L2 can be put into the roller 200.

[0548] The small amount of clothing L1 can be less than half of the maximum weight that the roller 200 can hold, while the large amount of clothing L2 can be equal to or more than half of the maximum weight that the roller 200 can hold.

[0549] The clothing processing device of this invention can control at least one of the following: the rotation speed, the actual rate of rotation, and the change of rotation direction of the drum, depending on the amount of clothing put in.

[0550] Figure 28 The problem that occurs when dealing with a small quantity of clothing is shown.

[0551] Typically, when performing any drying process to remove moisture from clothes, the drum 200 rotates at a speed that allows the clothes to rise to a position higher than the rotation axis 530 and fall. As a result, the clothes can be separated from the inner wall of the drum 200 and directly exposed to the hot air introduced into the drum 200, thus being dried evenly.

[0552] However, when a small amount of clothing L1 is put into the roller 200, since the amount of clothing disposed at the lower part of the roller 200 is also small, the height between the upper clothing A that rises above the rotation axis 530 and the lower clothing B disposed at the lower part of the rotation axis 530 or the lower surface of the roller 200 is relatively high.

[0553] As a result, the upper garment A may shrink as it falls onto the lower garment B or the lower surface of the roller 200 due to the large impact.

[0554] Furthermore, as the lower garment B rises, it may collide and rub against the upper garment A, potentially causing damage such as pilling.

[0555] Therefore, when a small amount of clothing L1 is fed into the roller 200, the rotational speed of the roller 200 can be reduced compared to when a large amount of clothing L2 is fed into the roller 200.

[0556] Figure 29 An embodiment of controlling the rotational speed of the drum when a small amount of clothing is loaded is shown.

[0557] When a small amount of clothing L1 is fed into the drum 200, the clothing handling device of this invention can control the rolling action of the drive unit 500 so that the drum 200 rotates at a speed at which the clothing L1 cannot rise to a position above the rotation axis 530 or the rotation center O of the drum. This not only eliminates the impact of the small amount of clothing L1 falling, but also reduces friction between the clothing L1 to prevent damage.

[0558] On the other hand, even if the clothes L1 cannot rise fully, the contact area between a small number of clothes L1 is not large, so they can be fully exposed inside the drum and thus be dried.

[0559] In the clothing processing device of this utility model, when the small amount of clothing L1 is put into the drum 200, the drum 200 can rotate in a rolling motion during the heating stage S1, constant speed stage S2, deceleration stage S3, and cooling stage S4.

[0560] On the other hand, when performing this rolling action, a protective action can be applied to accommodate the changes in the actual rate and rotation direction.

[0561] Alternatively, in the clothing processing device of this utility model, when a small amount of clothing L1 is contained in the drum 200, it is not easy for them to get tangled or intertwined. The force of pushing the door 130 is also not large. Even if it contains moisture, the load on the drive unit 500 that rotates the drum 200 is not large. Therefore, the drum 200 can rotate normally.

[0562] Therefore, the clothing processing device of this utility model can prevent damage to a small amount of clothing L1 and prevent the drying of a small amount of clothing L1 from being delayed, thereby saving power consumption.

[0563] Figure 30 An embodiment of controlling the rotational speed of a drum when dealing with a large volume of clothing is shown.

[0564] In the clothing processing device of this utility model, when a large amount of clothing L2 is put into the roller 200, the drive unit 500 can be controlled to make the roller 200 rotate at a speed that allows the clothing to rise to a position above the rotation axis 530 and the rotation center O of the roller 200 and fall down.

[0565] In this case, the drive unit 500 can cause the roller 200 to rotate by a tumbling action, which causes the roller 200 to rotate at a speed less than the speed at which the clothing rotates once when it is attached to the inner wall of the roller.

[0566] When a large amount of clothing L2 is put into the roller 200, since all the clothing in the tumbling roller does not rise and fall at once, but rises and falls sequentially, the height from which the clothing falls can be relatively small.

[0567] Therefore, the clothes L2 rise to a position higher than the rotation center O and fall, so that a large number of clothes L2 can be evenly exposed to the hot air flowing into the drum 200 and dried.

[0568] In the clothing processing device of this utility model, when the large amount of clothing L2 is fed in, during any drying process, it is possible to utilize... Figure 14 and Figure 21 The drive unit 500 is controlled by the control method for applicable protective actions described in the document.

[0569] This eliminates the knotting and tangling of the clothing L2, prevents the door 130 from opening arbitrarily, and reduces the load on the drive unit 500, thereby saving power.

[0570] Figure 31 This paper demonstrates a control method that sets the rotation control of the roller according to the weight of the garment.

[0571] Typically, the roller 200 is installed inside the garment handling device in a non-replaceable manner, thus the liquor ratio of the roller 200 is fixed. Therefore, the garment handling device of this invention can determine whether to execute an applicable protective action based on the amount of garments input, regardless of the liquor ratio of the roller 200.

[0572] Furthermore, in order for the clothing handling device of this invention to set the driving mode of the drive unit 500 differently according to the weight of the clothing put into the roller 200, it is necessary to sense the weight of the clothing.

[0573] Therefore, in the garment processing apparatus of this utility model, when performing any drying process and executing the drying step, a rotation stage S10 can be executed, in which the roller 200 is rotated and the weight of the garment is sensed using the current value applied to or output from the drive unit 500.

[0574] The roller rotation stage S10 may be a stage corresponding to the aforementioned sensing stage S0.

[0575] The aforementioned sensing stage S0 can be understood as a concept that includes both of the following actions: sensing weight by rotating the roller; and sensing the weight of the clothing by a load sensor when a load sensor is provided.

[0576] When the rotation phase S10 is executed, a determination phase S20 can be executed to determine whether the sensed weight of the clothing is above a reference value.

[0577] The reference value can be equivalent to half of the maximum weight that can be accommodated in the drum 200. For example, if the drying capacity is set to 22 kg, the reference value can be equivalent to 11 kg.

[0578] When it is determined in the determination stage S20 that the clothing is a small amount of clothing L1, the continuous rotation stage S30, in which the roller 200 rotates in the normal operation, can be executed.

[0579] The continuous rotation stage S30 can be executed throughout the entire range from the heating stage S1 to the constant speed stage S2, the deceleration stage S3, and the cooling stage S4, and can be executed until the drying process ends.

[0580] During the continuous rotation phase S30, the drive unit 500 can be controlled to rotate the roller 200 in a rolling motion. However, during the continuous rotation phase S30, the roller 200 can also be controlled to rotate in a flipping motion.

[0581] When the continuous rotation phase S30 is determined, the drive unit 500 can be controlled to drive at a set activation rate of 100%, and the drum 200 rotates continuously without interruption. As a result, a small amount of clothing L1 can be dried quickly, thereby saving power consumption.

[0582] When it is determined in the determination stage S20 that the clothing is a large quantity of clothing L2, the intermittent rotation stage S40, which causes the roller 200 to rotate with the protection action and interrupts the repetitive rotation of the roller, can be executed.

[0583] The intermittent rotation phase S40 can be performed in at least any one of the entire interval from heating phase S1 to constant speed phase S2, deceleration phase S3 and cooling phase S4.

[0584] Executing the intermittent rotation phase S40 can correspond to the applicable Figure 14 or Figure 21 The control method shown.

[0585] During the intermittent rotation phase S40, the drive unit 500 can be controlled to make the roller 200 rotate by tumbling.

[0586] Figure 32 An embodiment of the drying process is shown during the continuous rotation phase S30.

[0587] During the sensing phase S0, a roller rotation phase S10 can be performed. The roller rotation phase S10 can cause the roller 200 to rotate in a rolling motion, or the roller 200 to rotate more slowly than a rolling motion, or the roller 200 to rotate less than one revolution.

[0588] Therefore, when the sensing phase S0 is executed, the power consumption of the drive unit 500 can be reduced, and the weight of the clothing can be quickly sensed.

[0589] When the continuous rotation phase S30 is determined to be executed, the roller 200 can be rotated from the heating phase S1 to the cooling extreme S4 ​​at a constant speed without interruption.

[0590] From the heating stage S1 onwards, the roller 200 can rotate at a faster speed than the roller rotates during the sensing stage S0.

[0591] The heating phase S1, the constant speed phase S2, and the deceleration phase S3 can be performed in a rolling motion.

[0592] Figure 33 An example of performing the drying process when executing the intermittent rotation stage S40 is shown.

[0593] In the sensing phase S0, the drum rotation phase S10 can be performed.

[0594] During the roller rotation stage S10, the roller can rotate in a rolling motion, or the roller 200 can rotate slower than a rolling motion, or the roller 200 can rotate less than one revolution.

[0595] Therefore, when the sensing phase S0 is performed, the power consumption of the drive unit 500 can be reduced, and the weight of the clothing can be quickly sensed.

[0596] The heating stage S1, the constant speed stage S2, and the deceleration stage S3 can be performed by tumbling while the drum is rotating.

[0597] This allows for the rapid and even drying of large quantities of clothing, thereby reducing overall power consumption.

[0598] Furthermore, the heating stage S1, the constant speed stage S2, and the deceleration stage S3 can be combined with... Figure 21 The same implementation method applies to the example. This prevents clothing from tangling and knotting, and also saves power consumption in the drive unit.

[0599] Figure 34 The performance coefficient of the drying process of the garment handling device of this invention is shown to change when the protective action is applied and when the normal action is applied.

[0600] When the clothing processing device of this invention performs the drying process using the protective action, it increases the overall coefficient of performance (COP) compared to performing the drying process using the normal action.

[0601] The reason can be understood as follows: when the roller 200 is rotated in a protective action during at least one of the heating stage S1, constant speed stage S2 and deceleration stage S3, the tangling and knotting of the clothes are eliminated, and the clothes are evenly exposed to the hot air, thereby quickly drying the clothes.

[0602] In particular, during the constant speed phase S2 and the deceleration phase S3, since the clothes are dried to a certain level or above, they will not get tangled or knotted when the protective action is applied. The clothes repeatedly rise and fall, thus exposing more of them to the hot air, which further improves the drying efficiency.

[0603] However, during the heating stage S1, which is equivalent to the initial stage of the drying process, the clothes are not fully dried, have a very high moisture content, and are at their heaviest. Therefore, even if a protective action is applied during the heating stage S1 to prevent the clothes from knotting or tangling, the clothes may not rise sufficiently inside the drum 200 and may fall instead. The adhesion of the clothes to the inner wall of the drum is also stronger, and they may not be evenly exposed inside the drum.

[0604] Furthermore, in the heating stage S1, since the drive unit 500 is driven at a lower rate than in the constant speed stage S2 and the deceleration stage S3, the time that the clothes are exposed to hot air as they rise inside the drum 200 can be shortened.

[0605] Therefore, in at least a portion of the heating phase S1, the drying performance may be worse than when the drum 200 dries continuously without interruption. Consequently, if the drying performance is reduced, the moisture content in the air flowing into the evaporator 910 is also relatively reduced, inevitably leading to a decrease in the temperature of the refrigerant flowing into the compressor 930, and thus potentially reducing the efficiency of the compressor 930. Consequently, in the initial stage of the drying process, the coefficient of performance may temporarily decrease when a protective action is applied, compared to normal operation.

[0606] Even so, when the drive unit 500 is driven in normal operation during the heating stage S1, the knotting and tangling of the clothing intensifies, increasing the load on the drive unit 500, and the door 130 may also be subjected to a strong force from the opening 111.

[0607] Therefore, when the protective action is applied during the heating stage S1, the clothing handling device of this utility model can control the compressor 930 differently than when the normal action is applied.

[0608] Figure 35 An embodiment of controlling the compressor in the garment handling apparatus of this invention is shown.

[0609] This invention can control the drive speed and drive time of the compressor 930 differently from existing clothing processing devices.

[0610] For example, in this invention, when the heating stage S1 is performed, the drive speed and drive time of the compressor 930 can be controlled differently from the heating stage of existing clothing processing devices.

[0611] The actions of controlling the drive speed and drive time of the compressor 930 differently can be defined as compressor control.

[0612] The compressor control can be selectively applied based on the weight of the garments or the bath ratio of the drum.

[0613] For example, when the roller 200 is set to rotate with the aforementioned protective action, the compressor control can be set to apply simultaneously with this action.

[0614] When it is determined that the protection action will be performed, it can be determined that the compressor control will also be performed.

[0615] For example, if it is determined that at least one of the heating phase S1, the constant speed phase S2, and the deceleration phase S3 is executed with the protection action, it can be determined that compressor control is executed in the heating phase S1.

[0616] When the system is set to perform a protection action during the heating phase S1, the maximum drive speed of the compressor 930 can be controlled to be lower than the maximum drive speed during normal operation.

[0617] If the maximum drive speed of the compressor 930 is set to the first target speed H1 when the normal operation is applied, then the maximum drive speed of the compressor 930 can be set to the second maximum speed H2, which is less than the first target speed H1, when the protection operation is applied.

[0618] Therefore, in the heating stage S1, the compressor 930 is driven at a lower speed to reduce the power consumption of the compressor, thereby increasing the performance coefficient in the heating stage S1 range.

[0619] On the other hand, when the heating phase S1 is performed with a protective action, the maximum drive speed of the compressor 930 is reduced, and therefore the target temperature of the refrigerant discharged from the compressor 930 may also decrease.

[0620] For example, if it is set to make the refrigerant discharged from the compressor 930 reach a first target temperature T1 when the heating phase S1 is performed in normal operation, it can be set to make the refrigerant discharged from the compressor 930 rise to a second target temperature T2 that is lower than the first target temperature when the heating phase S1 is performed in protective operation.

[0621] When the heating phase S1 is executed with the aforementioned protection action, the constant speed phase S2 can be executed even before the refrigerant temperature reaches the first target temperature T1, once the refrigerant temperature reaches the second target temperature T2. That is, the drive speed of the compressor 930 may begin to decrease from this point.

[0622] Furthermore, in the garment processing apparatus of this invention, when the heating stage S1 is performed with a protective action compared to when the heating stage S1 is performed with the normal action, the temperature of the refrigerant and the drive speed of the compressor are reduced in the heating stage S1, so the temperature flowing into the interior of the drum 200 or the circulation pipe 820 may also be reduced.

[0623] Of course, even when the heating phase S1 is performed with a protective action, the drive speed of the compressor 930 can be set in such a way that the temperature of the refrigerant discharged from the compressor 930 can be raised to the first target temperature T1 during the constant speed phase S2.

[0624] As a result, in the clothing processing apparatus of this invention, during the heating phase S1 or the initial stage of the drying process when the performance coefficient of the drying process is lower when the drying process is performed with the protective action than when the drying process is performed with the normal action, the maximum drive speed or average drive speed of the compressor 930 can be reduced to save power consumption of the compressor and thereby improve the performance coefficient.

[0625] On the other hand, even if the drive speed of the compressor 930 is reduced, it can still be driven at the same speed as when the heating phase S1 is performed in normal operation, or even higher. Therefore, when the heating phase S1 is performed in the protective operation, the clothes can be dried in a manner similar to when the heating phase S1 is performed in normal operation.

[0626] In this invention, when the protection action is performed during the heating stage S1, the compressor 930 can be set to drive for a longer time than when performing normal operation.

[0627] Therefore, it is possible to compensate for the situation where the temperature of the air flowing into the drum 200 also decreases as the maximum temperature of the refrigerant discharged from the compressor 930 decreases.

[0628] In this invention, when the protection action is performed during the heating stage S1, the compressor 930 can be set to reach the target speed H more slowly than when performing normal operation.

[0629] Therefore, when the evaporator 910 can fully exchange heat with the air flowing into the circulation pipe 920, the compressor 930 can be driven to the maximum extent to ensure the coefficient of performance, ensuring that the evaporation of clothing is fully guaranteed.

[0630] In this invention, if the compressor 930 is set to drive for a first time t1 when performing the heating phase S1 in normal operation, it can be set to drive for an extended time t11 that is longer than the first time t1 when performing the heating phase S1 in a protective operation.

[0631] That is, the present invention can compensate for the situation where the temperature of the refrigerant discharged from the compressor 930 slowly reaches the maximum temperature by increasing the duration of the heating stage S1.

[0632] On the other hand, whether the drying process is performed as a normal operation or a protective operation can be determined based on the liquor ratio of the drum 200 (refer to...). Figure 26 ), or based on the weight of the clothes placed into the drum 200 (refer to Figure 31 )Sure.

[0633] When determining whether the clothing processing device of this utility model performs a protective action based on the bath ratio of the roller 200, since the bath ratio of the roller 200 is completely determined in the design, the compressor 930 can always accelerate to the second target speed H2 and drive during the heating stage S1, or the compressor 930 can always drive for an extended time t11.

[0634] That is, in the clothing processing device of this utility model, the drive speed of the compressor 930 can be set differently when the liquor ratio is above the set value and when the liquor ratio is below the set value.

[0635] For example, when the bath ratio of the drum 200 is below a set value, the maximum drive speed of the compressor can be controlled to be lower than when the bath ratio of the drum 200 is above a set value.

[0636] The set value can be determined to be 13 or less.

[0637] For example, the set value can be determined to be 10.5.

[0638] However, in the case where the garment handling device of this invention determines whether to perform the drying process with a protective action based on the weight of the garments put into the drum 200, the drive speed control of the compressor 930 can be determined based on the weight of the garments sensed in the sensing phase S0.

[0639] For example, in the clothing processing device of this invention, the drive speed of the compressor 930 can be set differently depending on whether the weight of the clothing is above a reference value or below a reference value.

[0640] The benchmark value can be equivalent to half of the maximum capacity.

[0641] Specifically, when the sensed weight of the garment is above a reference value, the maximum drive speed of the compressor 930 can be controlled to be below the reference value of the weight of the garment.

[0642] If the maximum drive speed of the compressor 930 is set to the first target speed H1 when the weight of the clothing is below the reference value, then when the weight of the clothing is above the reference value, the maximum drive speed of the compressor 930 can be set to the second target speed H2, which is less than the first target speed H1.

[0643] Therefore, by driving the compressor 930 at a lower speed during the heating stage S1, the power consumption of the compressor is reduced, thereby increasing the performance coefficient during the heating stage S1.

[0644] On the other hand, if the heating stage S1 is performed when the weight of the clothing is above the reference value, the maximum drive speed of the compressor 930 decreases, and therefore the target temperature of the refrigerant discharged from the compressor 930 can also be reduced.

[0645] For example, if the heating phase S1 is performed when the weight of the garment is below a reference value, causing the refrigerant discharged from the compressor 930 to reach a first target temperature T1, it can be set to perform the heating phase S1 when the weight of the garment is above a reference value, causing the refrigerant discharged from the compressor 930 to rise to a second target temperature T2, which is lower than the first target temperature.

[0646] When the heating phase S1 is performed when the weight of the clothing is above a reference value, the constant speed phase S2 can be performed even before the refrigerant temperature reaches the first target temperature T1 when the refrigerant temperature reaches the second target temperature T2. That is, the drive speed of the compressor 930 may begin to decrease from this point.

[0647] Furthermore, in the garment processing apparatus of this invention, compared to the case where the heating stage S1 is performed when the weight of the garment is below a reference value, when the heating stage S1 is performed when the weight of the garment is above a reference value, the temperature of the refrigerant and the drive speed of the compressor are reduced in the heating stage S1, so the temperature flowing into the interior of the drum 200 or the circulation pipe 820 may be reduced.

[0648] Of course, even when the heating phase S1 is performed when the weight of the garment is above the reference value, the drive speed of the compressor 930 can be set in such a way that the temperature of the refrigerant discharged from the compressor 930 can be raised to the first target temperature T1 during the constant speed phase S2.

[0649] As a result, in the clothing processing apparatus of this invention, during the heating phase S1 or the initial drying phase when the performance coefficient of the drying process is lower when the weight of the clothing is above the reference value compared to when the drying process is performed below the reference value, the maximum drive speed or average drive speed of the compressor 930 can be reduced to save power consumption of the compressor and thereby improve the performance coefficient.

[0650] On the other hand, even if the drive speed of the compressor 930 is reduced, it can still be driven at the same speed as when the heating stage S1 is performed in normal operation, or even higher. This ensures that when the heating stage S1 is performed when the weight of the garment is above a certain threshold, the garment can be dried in a manner similar to when the heating stage S1 is performed when the weight of the garment is below a certain threshold.

[0651] In this invention, it can be configured such that when the heating stage S1 is performed, the time during which the compressor 930 is driven is longer when the weight of the clothing is above a reference value than when the weight of the clothing is below a reference value.

[0652] Therefore, it is possible to compensate for the situation where the temperature of the air flowing into the drum 200 also decreases as the maximum temperature of the refrigerant discharged from the compressor 930 decreases.

[0653] In this invention, it can be configured such that when the heating stage S1 is performed, the time it takes for the compressor 930 to reach the target speed H is slower when the weight of the clothing is above a reference value than when the weight of the clothing is below a reference value.

[0654] Therefore, when the evaporator 910 can fully exchange heat with the air flowing into the circulation pipe 920, the compressor 930 can be driven to the maximum extent to ensure the coefficient of performance, ensuring that the evaporation of clothing is fully guaranteed.

[0655] The heating phase S1 can be set such that the circulation pipe reaches its maximum temperature more slowly when the sensed weight of the clothing is above a reference value than when the weight of the clothing is below a reference value.

[0656] In this invention, if the compressor 930 is set to drive for a first time t1 when the heating stage S1 is performed when the weight of the garment is below a reference value, it can be set to drive for an extended time t11 longer than the first time t1 when the heating stage S1 is performed when the weight of the garment is above a reference value.

[0657] That is, the present invention can compensate for the situation where the temperature of the refrigerant discharged from the compressor 930 slowly reaches the maximum temperature by increasing the duration of the heating stage S1.

[0658] In the clothing processing device of this utility model, when the weight of the clothing is above the reference value, compared to the case where the weight of the clothing is below the reference value, the compressor 930 can be driven at the maximum drive speed for a longer period of time.

[0659] Figure 36 The effect of simultaneously performing the compressor control and rotation control is shown.

[0660] It can be confirmed that when the compressor control and rotation control are executed simultaneously while the drying process is being executed, the performance coefficient increases further in the range where the performance coefficient decreases when the rotation control is executed.

[0661] Therefore, by controlling the compressor 930, even if the garment processing device of this invention performs rotation control, the performance coefficient can be improved from the heating stage S1 to carry out the drying process, and the result can be predicted to save power consumption and increase energy efficiency.

[0662] Figure 37 The effect of the present invention's clothing processing device when drying a large quantity of clothes is shown.

[0663] Data from existing garment handling devices may include cases where the drying process is performed without any rotation control or compressor control, or cases where the drying process is performed in the conventional manner without the rotation control and compressor control found in the garment handling device of this invention.

[0664] It can be confirmed that in the clothing processing device of this utility model, when a large amount of clothing is sensed being put into the roller 200, if rotation control such as a protective action is performed, the energy level is much higher than that of existing clothing processing devices.

[0665] This confirms that if the aforementioned compressor control is also performed simultaneously when rotation control is executed, the energy level will be further improved.

[0666] This data confirms that, in the case of a large amount of clothing (L2), rotary control is more effective than compressor control in improving energy efficiency.

[0667] The reason can be understood as follows: when dealing with a large amount of clothing (L2), reducing the load on the drive unit (500) results in greater energy savings compared to reducing the speed of the compressor (930).

[0668] Therefore, when the garment handling device of this invention senses a large amount of garments L2 contained in the drum 200 during the sensing stage S0, it must execute rotation control, thereby significantly saving power consumption. Furthermore, when executing the rotation control, the garment handling device of this invention also executes compressor control, thereby further saving power consumption.

[0669] The rotation control can be performed by setting different activation rates throughout the drying process, or the compressor control can be performed during the heating stage S1.

[0670] Figure 38 The effect of the present invention's clothing processing device when drying a small amount of clothing is shown.

[0671] It can be confirmed that in the clothing handling device of this utility model, when a small amount of clothing is sensed being put into the roller 200, if rotation control such as a protective action is performed, the energy level is higher than that of existing clothing handling devices.

[0672] However, it can be confirmed that when rotary control is executed, if the aforementioned compressor control is also executed simultaneously, the degree of energy level improvement is far greater than when only rotary control is executed without compressor control.

[0673] This data confirms that, for a small amount of clothing (L2), compressor control is more effective than rotary control in improving energy efficiency.

[0674] Therefore, when the clothing handling device of this invention senses a small amount of clothing L2 contained in the drum 200 during the sensing stage S0, it must execute compressor control, thereby saving power consumption.

[0675] Furthermore, rotation control can be performed simultaneously with compressor control to further save power consumption. The rotation control can be performed by setting different activation rates throughout the drying process, or compressor control can be performed during the heating phase S1.

[0676] Of course, when the garment handling device of this invention senses a small amount of clothing L2 contained in the drum 200 during the sensing stage S0, rotation control can be omitted while executing compressor control. This shortens the drying time for the small amount of clothing L1.

[0677] This utility model can be implemented in various forms, and its scope of claim is not limited to the above embodiments. Therefore, if a modified embodiment includes the constituent elements of the claims of this utility model, it should be considered to fall within the scope of the claims of this utility model.
