Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically providing a control method for a clothing processing device and the clothing processing device itself. Background Technology

[0002] Existing garment processing equipment mainly includes dryers and washer-dryer combos.

[0003] Both dryers and washer-dryer combos have a drying function, which mainly uses a drying device inside the machine to deliver hot air into the drum to dry the clothes inside.

[0004] When the drying mode is activated, the drum needs to rotate with the clothes, which will cause friction between the clothes and the drum, and may easily damage the clothes.

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that existing clothing processing equipment easily damages clothing when drying it.

[0007] In a first aspect, the present invention provides a control method for a garment processing device, the garment processing device comprising a housing and a drum, a drying device, and a fan installed within the housing, the drum being rotatable relative to the housing, the drying device being capable of extracting humid air from the drum, dehumidifying and heating it, and then returning it to the drum, the fan being located in front of the drum, and the fan being capable of blowing air towards the inner bottom of the drum, the control method comprising:

[0008] When the drying mode is executed, the drying device and the fan are operated;

[0009] Obtain the weight of the clothes in the drum;

[0010] Obtain a preset rotation / stop ratio corresponding to the weight of the garment;

[0011] The roller is made to run according to the preset rotation-stop ratio;

[0012] The preset rotation-to-stop ratio is positively correlated with the weight of the clothing.

[0013] In a preferred embodiment of the control method for the aforementioned garment processing equipment, the control method further includes:

[0014] The rotational speed of the roller is determined based on the weight of the garment;

[0015] The rotational speed is positively correlated with the weight of the clothing.

[0016] In a preferred embodiment of the control method for the aforementioned garment processing equipment, the control method further includes:

[0017] The duration of each rotation of the roller is determined based on the weight of the garment;

[0018] The duration is positively correlated with the weight of the clothing.

[0019] In the preferred embodiment of the control method for the aforementioned garment processing equipment, the step of "obtaining a preset start-stop ratio corresponding to the weight of the garment" specifically includes:

[0020] The weight of the garment is compared with a first preset value;

[0021] If the weight of the clothing is less than the first preset value, then the preset start-stop ratio is the first preset start-stop ratio;

[0022] If the weight of the clothing is not less than the first preset value, then the preset start-stop ratio is the second preset start-stop ratio;

[0023] Wherein, the first preset turn-to-stop ratio is less than the second preset turn-to-stop ratio.

[0024] In the preferred embodiment of the control method for the aforementioned garment processing equipment, the first preset start-stop ratio is less than 1:1; and / or

[0025] The second preset turn-to-stop ratio is greater than or equal to 1:1.

[0026] In a preferred embodiment of the control method for the aforementioned garment processing equipment, the control method further includes:

[0027] When the weight of the clothing is less than a second preset value, the roller is kept stationary at all times; and / or

[0028] The specific steps of "making the roller operate according to the preset rotation-stop ratio" include:

[0029] First, bring the roller to a standstill, then rotate it.

[0030] In a preferred embodiment of the control method for the above-mentioned clothing processing equipment, the clothing processing equipment further includes a damper assembly, which is used to shield the exhaust port of the fan, and the damper assembly can be opened by the air blown out of the exhaust port.

[0031] In the preferred embodiment of the control method for the above-mentioned garment processing equipment, the damper assembly includes an annular fixed plate and multiple independent dampers. The multiple dampers together cover the exhaust port. Each damper is provided with a limiting structure. After the damper is opened, the limiting structure abuts against the fixed plate to limit the damper to a set open position. When the multiple dampers are in the set open position, they are parallel to each other, and an air guide channel is formed between two adjacent dampers. The air guide channel faces the inner bottom of the roller.

[0032] In a preferred embodiment of the control method for the aforementioned garment processing equipment, the air inlet of the drying device is located below the opening of the drum, and the air outlet of the drying device is connected to the rear end of the drum; and / or

[0033] The fan is tilted downwards to discharge air.

[0034] In a second aspect, the present invention also provides a garment processing apparatus, including a controller configured to perform the control method described above.

[0035] In the case of adopting the above technical solution, during the drying mode, the clothing processing equipment of the present invention not only operates the drying device, but also operates the fan in front of the drum. The fan blows air onto the clothes located at the bottom of the drum, and the air blown by the fan directly onto the clothes, which can remove the moisture from the clothes and improve the heat exchange efficiency between the clothes and the drying airflow. After the clothes are still for a period of time, the drum rotates with the clothes, causing the clothes to tumble and redistribute so that multiple sides of the clothes can come into contact with the air blown by the fan. By making the drum operate according to a preset rotation-stop ratio, that is, making the drum rotate intermittently, it is beneficial to reduce the mechanical wear on the clothes. In addition, since the fan is installed in front of the drum, it can blow air directly into the drum through the drum opening, and the air force is stronger. The fan can provide strong air to impact the clothes in the drum, which can quickly disperse the knotted and clump-like clothing fibers, making the clothes fluffier and improving the drying effect. Furthermore, the strong air also helps to remove dust, hair and other impurities from the clothes.

[0036] Furthermore, the garment processing device of the present invention uses different rotation speeds for the rollers to rotate for garments of different weights. The lighter the garment, the lower the rotation speed of the roller. This setting can further reduce wear and tear on the garment.

[0037] Furthermore, the garment processing device of the present invention adjusts the duration of each roller rotation for garments of different weights; the lighter the garment, the shorter the duration of each roller rotation. This setting further reduces wear and tear on the garments.

[0038] Furthermore, the clothing processing device of the present invention can dry clothes even when the weight of the clothes in the drum is less than a second preset value, and the drum remains stationary throughout the drying process without rotating, which is beneficial to achieving zero wear.

[0039] Furthermore, the garment processing device of the present invention provides a damper assembly for shielding the exhaust port of the fan. When the fan is not required to operate, the damper assembly shields the exhaust port of the fan, preventing impurities such as lint from entering the fan. The damper assembly is designed to open by air blown from the exhaust port of the fan, which is more energy-efficient.

[0040] Furthermore, the garment processing device of the present invention limits the opening angle of the air damper by setting a limiting structure on the damper to a set opening position, thereby preventing the airflow from escaping from the exhaust port due to excessive opening angle. In addition, by making the dampers parallel when open, an air guide channel is formed between adjacent dampers. The airflow from the exhaust port of the fan flows along the air guide channel to the inner bottom of the roller, which can more effectively prevent airflow from escaping and make the airflow stronger.

[0041] Furthermore, the garment processing device of the present invention, by tilting the fan downwards to discharge air, is more conducive to the circulation of airflow between the drum and the fan. Attached Figure Description

[0063] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0064] Those skilled in the art should understand that although the steps of the control method of the present invention are described in a specific order in this application, this order is not restrictive. Without departing from the basic principles of the present invention, those skilled in the art can perform the steps in different orders. For example, the execution order of steps S100 and S200 of the control method of the present invention can be interchanged, or steps S100 and S200 can be performed simultaneously. The adjusted technical solution is equivalent to the technical solution described in this application and therefore will also fall within the protection scope of the present invention.

[0065] It should be noted that in the description of this invention, terms such as "horizontal," "vertical," "left," and "right," which indicate direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0066] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0067] Specifically, the present invention provides a garment processing device, such as... Figure 1 As shown, the garment processing device of the present invention includes a housing 1 and a roller 2 installed inside the housing 1, the roller 2 being rotatable relative to the housing 1.

[0068] The garment processing equipment of the present invention can be a washer-dryer combo machine, which includes an outer drum and an inner drum rotatably disposed in the outer drum. A drive device is provided at the rear end of the outer drum, and the drive device is used to drive the inner drum to rotate. The drum 2 is the inner drum.

[0069] The clothing processing equipment of the present invention can also be a dryer, and the drum 2 is a drying drum. Whether it is a dryer or a washer-dryer combo, a drying device is also installed in the housing 1. The drying device can extract the humid air in the drum 2, dehumidify and heat it and send it back to the drum 2. By making the airflow circulate between the drum 2 and the drying device, the clothes in the drum 2 can be dried.

[0070] For example, the drying device includes a heat pump module, a drying fan 32, and a drying duct 31. The two ends of the drying duct 31 are connected to the front end and the rear end of the drum 2, respectively. The evaporator 33 and the condenser 34 of the heat pump module are both installed in the drying duct 31. The evaporator 33 is located upstream of the condenser 34. The evaporator 33 is used to dehumidify the humid air, and the condenser 34 is used to heat the airflow. The drying fan 32 is also installed in the drying duct 31 so that the airflow can circulate between the drum 2 and the drying duct 31.

[0071] It should be noted that those skilled in the art can also use other types of dehumidification components and heating components to replace the evaporator 33 and condenser 34 described above in practical applications. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0072] Furthermore, it should be noted that, in practical applications, those skilled in the art can position the air inlet of the drying device closer to the front end of the drum 2 and the air outlet of the drying device closer to the rear end of the drum 2. During the drying process, the humid air inside the drum 2 is discharged from the front end of the drum 2 and enters the drying device. After being dehumidified and heated by the drying device, it re-enters the drum 2 from the rear end. Alternatively, the air inlet of the drying device can be positioned closer to the rear end of the drum 2 and the air outlet of the drying device closer to the front end of the drum 2. During the drying process, the humid air inside the drum 2 is discharged from the rear end of the drum 2 and enters the drying device. After being dehumidified and heated by the drying device, it re-enters the drum 2 from the front end. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0073] Preferably, such as Figure 1 As shown, the air inlet of the drying device of the present invention is located below the opening of the drum 2, and the air outlet of the drying device is connected to the rear end of the drum 2.

[0074] For example, such as Figure 1 As shown, the drying device is located below the drum 2, and the drying air duct 31 extends from the front end of the drum 2 (from... Figure 1 (Viewed from above, left end) extends to the rear end of roller 2 (from...) Figure 1 (Viewed from the top, right end) When the drying program is executed, the drying fan 32 is started, and the humid air in the drum 2 is discharged from the drum opening and enters the drying air duct 31. Then it flows along the drying air duct 31 toward the rear end of the drum 2. After dehumidification and heating, it enters the drum 2 from the rear end to dry the clothes in the drum 2.

[0075] Preferably, such as Figure 1As shown, the garment processing device of the present invention also includes a lint collection box 4 installed at the opening of the drum 2. The airflow discharged from the drum opening first flows through the lint collection box 4 and then enters the drying device.

[0076] The lint collection box 4 can filter and collect impurities such as lint carried by the airflow, preventing impurities from entering the drying air duct 31.

[0077] Preferably, such as Figure 1 As shown, the garment processing equipment of the present invention also includes an air supply device installed in the housing 1. The air supply device is located in front of the roller 2 and can supply air toward the inner bottom of the roller 2.

[0078] During the drying process, air is delivered to the bottom of the inner drum 2 via the air supply device, allowing the air to directly blow onto the clothes located at the bottom of the drum 2. This improves the efficiency of heat and moisture exchange between the clothes and the drying airflow, thereby increasing the drying efficiency of the clothing processing equipment and accelerating the drying speed. In addition, since the air supply device is installed at the front of the drum 2, it can blow air directly into the drum 2 through the drum opening, resulting in stronger airflow. This allows the air supply device to provide strong airflow to impact the clothes in the drum 2, making the clothes fluffier and more comfortable for the user to wear. Furthermore, the strong airflow also helps to remove dust, hair, and other impurities from the clothes.

[0079] Preferably, such as Figure 1 As shown, the air blown out by the air supply device of the present invention enters the drum 2 and flows towards the rear end of the drum 2, then turns back and flows towards the front end of the drum 2, and is discharged from the cylinder opening at the front end of the drum 2 and then enters the air supply device.

[0080] In other words, in addition to the circulating airflow between the drying device and the drum 2, the air supply device and the drum 2 can also form a circulating airflow. The two circulating airflows merge with each other, which can further improve the drying efficiency.

[0081] It should be noted that, when a drying device and a lint collection box 4 are provided, it is preferable that the airflow discharged from the cylinder opening of the drum 2 first flows through the lint collection box 4, and then is divided into two airflows that enter the drying device and the air supply device respectively.

[0082] With the above settings, the garment processing equipment not only has a drying function, but also a dust and hair removal function. Specifically, when a user's clothes have dust or a lot of hair (such as cat hair), but the user does not want to wash the clothes, the clothes can be placed in the drum 2 of the garment processing equipment, and then the air supply device is turned on. The air supply device blows air into the drum 2, and when the strong wind blows onto the clothes, it can carry away the dust and hair on the clothes. When the circulating airflow flows through the lint collection box 4, the dust and hair are filtered and collected by the lint collection box 4, thereby removing the dust and hair from the clothes.

[0083] Preferably, such as Figure 4 As shown, the lint collection box 4 of the present invention includes a first filter frame 41, a second filter frame 42, a first filter (not shown in the figure) disposed on the first filter frame 41, a second filter (not shown in the figure) disposed on the second filter frame 42, and a top cover 43. The first filter frame 41 and the second filter frame 42 are arranged in a V-shape. The bottom end of the first filter frame 41 and the bottom end of the second filter frame 42 are connected, preferably by a pivot connection. The top end of the first filter frame 41 and the top end of the second filter frame 42 are both connected to the top cover 43. The top cover 43 is provided with a plurality of air inlets 431.

[0084] The airflow discharged from the cylinder opening of the roller 2 passes through the air inlet 431 on the top cover 43 and enters the lint collection box 4. After being filtered by the first filter screen and the second filter screen, it is discharged. The filtered lint and other impurities are collected in the cavity between the first filter screen and the second filter screen.

[0085] Preferably, such as Figures 1 to 3 As shown, the air supply device of the present invention supplies air at an angle downwards.

[0086] The air outlet of the air supply device is higher than the opening of the drum 2. The air blown out from the air supply device flows obliquely downward to the inner bottom of the drum 2. After a certain refraction, it flows obliquely upward toward the rear end of the drum 2. Then, after being refracted by the rear wall of the drum 2, it flows toward the front end of the drum 2. In other words, by making the air supply device tilt downward, it is more conducive to the airflow circulating between the drum 2 and the air supply device.

[0087] Preferably, such as Figure 3 As shown, the distance from the point where the extension line of the air outlet direction of the air supply device intersects with the inner bottom of the drum 2 to the axis of the drum opening of the drum 2 is 1 / 4 to 3 / 4 of the axis length of the drum 2.

[0088] In other words, the air blown out by the air supply device should preferably fall to 1 / 4 to 3 / 4 of the drum 2, which is... Figure 3 The area between points a and c is designed to facilitate airflow circulation between roller 2 and the air supply device. Ideally, the air blown by the air supply device should reach the middle of roller 2, specifically at the halfway point. Figure 3 Point b is located to the left and right of the middle point.

[0089] It should be noted that, in addition to using the above method to limit the air outlet direction of the air supply device, it can also be limited by the angle between the air outlet direction and the axial direction of the roller 2. Preferably, the angle between the extension line of the air outlet direction of the air supply device and the axial direction of the roller 2 is 45 degrees to 85 degrees.

[0090] For example, the angle between the extension line of the air outlet direction of the air supply device and the axial direction of the roller 2 is 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees or 85 degrees.

[0091] Preferably, such as Figures 1 to 3 As shown, the air supply device of the present invention includes a fixed component 6 and a fan 5. The fan 5 is mounted on the fixed component 6 and located in front of the roller 2. The exhaust port of the fan 5 faces the inner bottom of the roller 2.

[0092] In other words, the clothing processing equipment of the present invention is equivalent to having two fans. One of them is a drying fan 32 of the drying device, which is installed in the drying air duct 31. The main function of the drying fan 32 is to deliver hot air into the drum 2. The other is a fan 5 directly installed at the front end of the drum 2. The main function of the fan 5 is to deliver strong air into the drum 2, generate a strong cyclone, which can lift the clothes in the drum 2, accelerate the drying of the clothes, and help reduce the damage to the clothes caused by friction.

[0093] For example, the fixing member 6 is fixedly connected to the housing 1 and is located between the roller 2 and the front panel of the housing 1, and the fan 5 is fixedly installed on the fixing member 6. The lint collection box 4 can also be installed on the fixing member 6.

[0094] It should be noted that those skilled in the art may omit the fixing component 6 in practical applications. In this case, the fan 5 can be installed on the front panel of the housing 1, or on the door, or on the window pad between the door and the roller 2, etc. Such adjustments and changes to the specific installation position of the fan 5 do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0095] Preferably, such as Figure 3 and Figure 5 As shown, the fixed component 6 is provided with a receiving cavity and an air outlet 61 communicating with the receiving cavity. The fan 5 is fixedly installed in the receiving cavity, and the exhaust port of the fan 5 faces the air outlet 61 on the fixed component 6.

[0096] After the airflow inside the drum 2 is discharged from the drum opening, it first flows through the wire shavings collection box 4 at the drum opening. After being filtered by the wire shavings collection box 4, the airflow is drawn into the fan 5. The airflow discharged from the exhaust port of the fan 5 passes through the air outlet 61 on the fixed component 6 and blows towards the inner bottom of the drum 2. The exhaust port of the fan 5 is inclined downward to discharge air.

[0097] It should be noted that the present invention does not limit the shape of the air outlet 61. For example, those skilled in the art can set the air outlet 61 to be circular, square, or off-center, etc. Such adjustments and changes to the specific shape of the air outlet 61 do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0098] Preferably, such as Figure 5 As shown, the fixing component 6 has a baffle 62 inside the air outlet 61 to prevent clothes in the roller 2 from entering through the air outlet 61.

[0099] By setting baffles 62 inside the air outlet 61 of the fixed component 6, it is possible to prevent clothing from entering the air outlet 61 and to more effectively prevent clothing from passing through the air outlet 61 and entering the fan 5.

[0100] Preferably, such as Figure 5 As shown, there are multiple baffles 62, which are distributed at radial intervals along the air outlet 61.

[0101] For example, the air outlet 61 is circular, and there are three baffles 62, which are horizontally arranged and spaced apart along the diameter of the air outlet 61. Furthermore, a vertical baffle 62 is provided in the middle of the three baffles 62, which intersects the three horizontal baffles 62 perpendicularly.

[0102] It should be noted that, in practical applications, those skilled in the art can make the retaining rib 62 integrally set with the fixing member 6, or connect it to the fixing member 6 by plugging or snapping, etc. Such adjustments and changes to the specific connection method between the retaining rib 62 and the fixing member 6 do not deviate from the principle and scope of the present invention, and should all be limited to the protection scope of the present invention.

[0103] Preferably, the air supply device of the present invention further includes a filter screen (not shown in the figure), which is installed at the air inlet of the fan 5 to prevent lint from entering the fan 5.

[0104] By installing a filter screen at the air intake of the fan 5, lint can be prevented from entering the fan 5. Especially when a lint collection box 4 is installed, the airflow is filtered twice before entering the fan 5, resulting in a better filtration effect.

[0105] Preferably, such as Figures 6 to 11 As shown, the air supply device of the present invention also includes a damper assembly, which is used to shield the exhaust port of the fan 5.

[0106] When the air supply device is not required to operate, the exhaust port of the fan 5 can be blocked by the damper assembly to prevent water inside the drum 2 from splashing into the outer casing of the fan 5. In addition, during the operation of the drying device, the drying airflow can be prevented from entering the outer casing of the fan 5 from the exhaust port, thereby preventing impurities such as lint from entering the fan 5.

[0107] It should be noted that, in practical applications, those skilled in the art can configure the damper assembly as a wind-driven damper, that is, the damper assembly opens by air blown from the exhaust port of the fan 5. Alternatively, the damper assembly can be configured as an electric damper, that is, the damper is opened by a motor. Such adjustments and changes to the specific type of damper assembly do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0108] Preferably, such as Figures 6 to 11 As shown, the damper assembly of the present invention includes an annular fixing plate 71 and a damper 72, the damper 72 being pivotally connected to the fixing plate 71.

[0109] For example, the fixing plate 71 is fixedly connected to the housing of the fan 5, and the through hole in the middle area of ​​the fixing plate 71 is aligned with the exhaust port of the fan 5. The shape and size of the through hole match the shape and size of the exhaust port of the fan 5.

[0110] It should be noted that, in practical applications, those skilled in the art may also fix the fixing plate 71 to the fixing component 6 for installing the fan 5 or set it as an integral part, or they may also cancel the setting of the fixing plate 71 and directly pivot the damper 72 to the outer casing of the fan 5, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should all be limited to the protection scope of the present invention.

[0111] In addition, it should be pointed out that, such as Figure 6 As shown, if an electrically operated damper is used, a motor 73 also needs to be installed on the fixed plate 71. The motor 73 drives the damper 72 to open, as shown. Figure 7 As shown, if a wind-powered damper is used, there is no need to install a motor 73. The damper 72 can be opened by the air blown out of the exhaust port of the fan 5.

[0112] Preferably, such as Figures 6 to 9 As shown, there are multiple dampers 72, each of which is independent, and together they cover the exhaust port of the fan 5.

[0113] When damper 72 is in the closed state, such as Figure 9 As shown, it is preferable that there is an overlap between two adjacent dampers 72, so that the exhaust port of the fan 5 can be better shielded.

[0114] It should be noted that if it is an electric damper 72, such as Figure 6 As shown, preferably each damper 72 is equipped with one motor 73, and each damper 72 can be opened independently by the motor 73. For example, there are four dampers 72 and four motors 73, and the four motors 73 drive the four dampers 72 independently.

[0115] Preferably, such as Figures 6 to 11 As shown, the damper 72 is provided with a limiting structure. After the damper 72 is opened, the limiting structure abuts against the fixing plate 71 to limit the damper 72 to a set open position.

[0116] By setting a limiting structure to confine the damper 72 to a set opening position, the opening angle of the damper 72 can be limited, preventing the airflow discharged from the exhaust port of the fan 5 from dissipating excessively due to an excessively large opening angle. In addition, for wind-driven dampers, setting a limiting structure to confine the damper 72 to a set opening position can prevent the damper 72 from failing to close due to its own gravity because the opening angle is too large.

[0117] Preferably, such as Figure 8 As shown, multiple dampers 72 are parallel to each other when they are in the set open position, and an air guide channel is formed between two adjacent dampers 72. The air guide channel faces the air outlet 61, that is, towards the inner bottom of the roller 2.

[0118] After the damper 72 is opened, each damper 72 is restricted to a set opening position by its own limiting structure. An air guide channel is formed between two adjacent dampers 72. The airflow discharged from the exhaust port of the fan 5 flows along the air guide channel to the air outlet 61 on the fixed member 6. After passing through the air outlet 61, it flows to the inner bottom of the roller 2, which can more effectively prevent the airflow from escaping and make the wind stronger.

[0119] Preferably, such as Figures 6 to 11 As shown, the damper 72 includes a plate-shaped body 721 and a rotating shaft 722 disposed on the plate-shaped body 721. The rotating shaft 722 is pivotally connected to the fixed plate 71, and a limiting structure is disposed on the rotating shaft 722.

[0120] For example, a plurality of slots 711 are provided on the fixed plate 71, and a rotating shaft 722 is provided on each side of the plate-shaped body 721 of the damper 72. Each rotating shaft 722 is rotatably connected to a corresponding slot 711. When the damper 72 is opened, the limiting structure rotates with the rotating shaft 722. When the limiting structure abuts against the fixed plate 71, it can prevent the rotating shaft 722 from continuing to rotate, thereby limiting the damper 72 to a set opening position. The plurality of plate-shaped bodies 721 are arranged in parallel, and an air guide channel is formed between two adjacent plate-shaped bodies 721.

[0121] It should be noted that the shape of the plate-shaped body 721 of each damper 72 can be the same or different. Preferably, the shape of the plate-shaped body 721 of each damper 72 is set according to the shape of the exhaust port of the fan 5.

[0122] For example, if the exhaust vent is square, the shape of the plate-shaped body 721 of each damper 72 can be set to be the same. If the exhaust vent is round, it is preferable to match the shape of the plate-shaped body 721 of each damper 72 with the shape of the exhaust vent at its installation location.

[0123] Furthermore, it should be noted that the present invention does not limit the specific structural form of the limiting structure. For example, those skilled in the art can set the limiting structure as a limiting block, a limiting plate, or a limiting post, etc.

[0124] Preferably, such as Figures 6 to 11 As shown, the limiting structure is a limiting block 723, which has a stop surface 7231. When the damper 72 is opened to the set opening position, the stop surface 7231 abuts against the fixing plate 71.

[0125] For example, the limiting block 723 is approximately fan-shaped, and the top end face of the limiting block 723 is a stop surface 7231.

[0126] Preferably, the limiting block 723 is provided with a hollow structure (not shown in the figure), and the hollow structure is located near the stop surface 7231.

[0127] By setting a hollow structure near the stop surface 7231, the lower part of the limit block 723 is heavier than the upper part, which makes it easier for the damper 72 to close by its own weight.

[0128] Based on any of the garment processing devices described above, the present invention also provides a control method for the garment processing device, such as... Figure 12 The control method of the present invention includes the following steps:

[0129] S100: When executing the drying mode, the drying unit and the fan are operated;

[0130] S200: Obtain the weight of the clothes in the drum;

[0131] S300: Obtain the preset rotation / stop ratio corresponding to the weight of the clothing;

[0132] S400: Enables the rollers to operate according to a preset rotation-stop ratio;

[0133] Among them, the preset rotation-to-stop ratio is positively correlated with the weight of the clothing.

[0134] In other words, during the drying mode, in addition to running the drying device, the fan in front of the drum also runs, blowing air onto the clothes located at the bottom of the drum. The air blown by the fan directly onto the clothes can remove moisture from them, which helps to improve the efficiency of heat and moisture exchange between the clothes and the drying airflow. After the clothes have been still for a period of time, the drum rotates with the clothes, causing them to tumble and redistribute, so that multiple sides of the clothes can come into contact with the air blown by the fan. By running the drum according to a preset rotation-stop ratio, that is, by making the drum rotate intermittently, it helps to reduce mechanical wear on the clothes.

[0135] The rotation-to-stop ratio refers to the ratio of the time the drum rotates to the time it stops. The controller of the garment processing equipment has several different preset rotation-to-stop ratios. The specific preset rotation-to-stop ratio to use depends on the weight of the garments in the drum. The preset rotation-to-stop ratio is positively correlated with the weight of the garments. That is, the lighter the garments are, the smaller the preset rotation-to-stop ratio is, the smaller the proportion of drum rotation is, and the larger the proportion of drum stopping is. In this way, the wear and tear on the garments is reduced.

[0136] Preferably, the step of "making the roller run according to the preset rotation-stop ratio" specifically includes: first making the roller stand still, and then making the roller rotate.

[0137] In other words, when the drying mode is started, the drum is not turned at first. Instead, the fan blows air into the clothes in the drum. After a period of time, the drum is turned to rotate, causing the clothes to tumble and redistribute. This is more conducive to reducing wear and tear on the clothes.

[0138] Preferably, the step of "obtaining the preset rotation-to-stop ratio corresponding to the weight of the clothing" specifically includes:

[0139] Compare the weight of the clothing with a first preset value;

[0140] If the weight of the clothing is less than the first preset value, the preset start-stop ratio is the first preset start-stop ratio;

[0141] If the weight of the clothing is not less than the first preset value, then the preset start-stop ratio is the second preset start-stop ratio;

[0142] The first preset turn-to-stop ratio is less than the second preset turn-to-stop ratio.

[0143] In other words, the present invention divides the weight of clothing into two intervals by a first preset value. When the weight of clothing is less than the first preset value, it means that the weight of clothing in the drum is relatively small, and the drum operates according to the first preset rotation-stop ratio. When the weight of clothing is not less than the first preset value, it means that the weight of clothing in the drum is relatively large, and the drum operates according to the second preset rotation-stop ratio.

[0144] For example, the first preset value is 2kg, the first preset rotation-to-stop ratio is 1:5, and the second preset rotation-to-stop ratio is 1:1. If the weight of the clothes in the drum is less than 2kg, the drum stops for 5 times the drum rotates. If the weight of the clothes in the drum is greater than or equal to 2kg, the drum stops for the same amount of time as the drum rotates.

[0145] It should be noted that the first preset value is not limited to the aforementioned 2kg. Those skilled in the art can flexibly set the specific value of the first preset value based on experiments or experience in practical applications. Furthermore, the present invention is not limited to dividing the weight of clothing into two intervals. Those skilled in the art can also set multiple different preset values ​​(e.g., 1kg, 2kg, 3kg, 4kg, and 5kg, etc.) to divide the weight of clothing into multiple different intervals, and set different switching ratios for each interval.

[0146] Furthermore, it should be noted that the first preset turn-to-stop ratio is not limited to 1:5 as described above. For example, it can also be set to 1:2, 1:3, 1:7, or 1:10, etc. Of course, it is preferable to make the first preset turn-to-stop ratio less than 1:1.

[0147] Furthermore, it should be noted that the second preset turn-to-stop ratio is not limited to 1:1 as described above. For example, it can also be set to 1.2:1, 1.5:1, 1.8:1, or 2:1, etc. Of course, it is preferable that the second preset turn-to-stop ratio is greater than or equal to 1:1.

[0148] Preferably, the control method of the present invention further includes: keeping the roller stationary when the weight of the clothing is less than a second preset value.

[0149] In other words, if the weight of the clothes in the drum is less than the second preset value, it means that the weight of the clothes in the drum is very small. In this case, the drum remains stationary throughout the drying process, and the clothes can still be dried without the drum rotating. This helps to achieve zero wear and tear on the clothes.

[0150] For example, the second preset value is 0.5 kg, so that the drum remains stationary when the weight of the clothes in the drum is less than 0.5 kg.

[0151] It should be noted that the specific value of the second preset value is not limited to 0.5 kg as mentioned above. For example, it can also be set to 0.3 kg, 0.8 kg or 1.0 kg, etc. Those skilled in the art can flexibly set the specific value of the second preset value based on experiments or experience in practical applications.

[0152] Furthermore, it should be noted that, in practical applications, those skilled in the art may set only one fixed rotation speed, and make the drum rotate at that fixed rotation speed each time the drying mode is executed. Alternatively, multiple different rotation speeds may be set, and a suitable rotation speed may be selected according to the actual situation each time the drying mode is executed. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0153] Preferably, the control method of the present invention further includes: determining the rotational speed of the drum based on the weight of the clothing.

[0154] The rotation speed is positively correlated with the weight of the clothes. In other words, the roller rotates at different speeds for clothes of different weights. The lighter the clothes, the lower the rotation speed of the roller. This setting can further reduce wear and tear on the clothes.

[0155] It should be noted that those skilled in the art can set specific rotation speed values ​​for different weights of clothing based on experiments or experience.

[0156] Furthermore, it should be noted that, in practical applications, those skilled in the art may set only one duration, and make the drum rotate according to that duration each time the drying mode is executed. Alternatively, multiple different durations may be set, and a suitable duration may be selected according to the actual situation each time the drying mode is executed. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0157] Preferably, the control method of the present invention further includes: determining the duration of each rotation of the roller based on the weight of the clothing.

[0158] The duration of rotation is positively correlated with the weight of the clothing. In other words, the duration of each rotation of the roller is different for clothing of different weights. The lighter the clothing, the shorter the duration of each rotation of the roller. This setting can further reduce wear and tear on the clothing.

[0159] It should be noted that those skilled in the art can set specific values ​​for the duration corresponding to different weights of clothing based on experiments or experience.
