Description

Technical Field

[0001] This invention belongs to the field of mechanical equipment technology, specifically, it relates to a clothing processing device and its control method. Background Technology

[0002] Clothing processing equipment refers to all devices used for managing clothing, such as washing, drying, and wrinkle removal.

[0003] If the user fails to remove the clothes promptly after the garment processing device has finished processing them, the clothes may become moldy or develop an odor due to prolonged exposure to a sealed environment. In particular, clothes that have not been dried after washing have relatively high humidity levels, and if the moisture inside the garment processing device cannot be removed in time, bacteria are more likely to grow.

[0004] For some garment handling devices with drying functions, the temperature inside the device is still high after drying, requiring a long period of natural cooling before the device can be opened to remove the clothes. This results in a long drying cycle, wasting a lot of time, and users are also at risk of being burned by the high temperature inside the device.

[0005] Currently, some garment processing devices are equipped with vents to allow airflow between the inside of the device and the outside, thus removing moisture. However, these vents are always open. During the washing process, wash water can easily splash out of the device through the vents; during the drying process, air can leak through the vents, reducing drying efficiency and posing a risk of burns to users.

[0006] In view of this, the present invention is hereby proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the problems of existing clothing processing devices where washing water easily splashes out of the outside of the clothing processing device through the vent during the washing process and air easily leaks through the vent during the drying process. The present invention provides a clothing processing device and its control method, which enables the clothing processing device to be connected to the outside air through the vent while avoiding water and air leakage through the vent.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: the garment handling device includes a tubular body and a vent for connecting the tubular body and the outside, and further includes a door assembly disposed on the vent, the door assembly including:

[0024] Preferably, the position sensor is a contact sensor;

[0025] Preferably, the contact sensor is disposed at the edge of the vent, and the door has a closed state in contact with the sensor and an open state apart from the sensor.

[0026] Furthermore, the garment handling device includes a box, and the cylinder includes an outer cylinder disposed inside the box, characterized in that: the vent and door assembly are disposed on the outer cylinder; or, the vent and door assembly are disposed on the box, and the outer cylinder is connected to the vent.

[0027] Furthermore, it includes a condenser disposed outside the cylinder, the condenser including a shell structure with an internal cavity, the shell structure communicating with the inside of the cylinder, and the vent and door assembly disposed on the shell wall of the condenser shell structure for communicating with the outside of the shell structure.

[0028] The present invention also discloses a control method for a clothing processing device applied to any of the above-described technical solutions. The clothing processing device includes a control system. After dehydration is completed, the control system controls the drive mechanism to drive the door to open the ventilation port.

[0029] Furthermore, the control method includes the following steps:

[0030] After S1 dehydration is completed, the control system controls and detects the humidity value inside the cylinder;

[0031] S2 When the detected humidity value is greater than the preset humidity value, the control system controls the drive mechanism to open the vent; when the detected humidity value is less than or equal to the preset humidity value, the control system closes the vent.

Users can adjust the fan speed according to their actual needs. Furthermore, the fan is integrated into the outer shell, facilitating the overall installation, disassembly, and replacement of both the fan and the outer shell.

[0056] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0058] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0059] like Figures 1 to 6 As shown, the present invention discloses a clothing processing device, which refers to all devices used for managing clothing, such as washing machines, dryers, and washer-dryer combos, for washing, drying, and wrinkle removal.

[0060] The garment handling device includes a drum body, which includes an outer drum 2 for holding washing water and an inner drum disposed inside the outer drum 2. A vent 11 for connecting the drum body to the outside is provided on the drum body, and a door assembly 1 disposed on the vent 11 is also included.

[0061] The door assembly 1 includes a door body 12 and a drive mechanism 13. The door body 12 is closable and can be installed on the ventilation opening 11. The drive mechanism 13 is connected to the door body 12 and is used to drive the door body 12 to close or open the ventilation opening 11.

[0062] This invention achieves the opening and closing of the vent 11 by setting a door assembly 1 on the vent 11. When the vent 11 is open, the gas inside the drum can circulate with the outside gas, which is beneficial for drying the inside of the drum; when the vent 11 is closed, it can prevent water droplets inside the drum from splashing to the outside of the drum. For clothing handling devices with drying function, after drying is completed, the vent 11 is opened to achieve rapid cooling inside the drum; during the drying process, the vent 11 is closed to prevent air leakage from the clothing handling device.

[0063] This invention achieves automated opening and closing of the door 12 by setting a drive mechanism 13, which is connected to the door 12. Under the drive of the drive mechanism 13, the door 12 opens and closes with high accuracy, and the ventilation opening 11 can be opened or closed without human intervention.

[0064] In this invention, a sealing gasket 16 can be provided on the edge of the vent 11 so that the door 12 has a good sealing effect after closing the vent 11, and there will be no air leakage at the contact surface between the door 12 and the vent 11, thereby improving the ventilation efficiency of the vent 11.

[0065] In one embodiment of the present invention, the garment handling device includes an air inlet system and an air outlet system. The air inlet system connects the inside of the garment tube to the outside atmosphere, and is used to introduce outside atmosphere into the garment tube; the air outlet system connects the inside of the garment tube to the outside, and is used to exhaust moisture inside the garment tube to the outside. Both the air inlet system and the air outlet system include a vent 11, and the door assembly 1 is disposed on the vent 11 of the air inlet system; or, the door assembly 1 is disposed on the vent 11 of the air outlet system; or, the door assembly 1 is disposed on the vent 11 of both the air inlet system and the air outlet system.

[0066] In this embodiment, by setting up an air intake system and an air outlet system, the outside air can enter the cylinder and the moisture inside the cylinder can be discharged to the outside of the cylinder, thus realizing the circulation of air inside the cylinder.

[0067] In one embodiment of the present invention, the door 12 is hinged to the vent 11. When it is necessary to open the vent 11, the door 12 is controlled to rotate away from the vent 11 to open the vent 11; conversely, when it is necessary to close the vent 11, the door 12 is controlled to rotate towards the vent 11 to close the vent 11.

[0068] As one implementation method of this embodiment, such as Figure 2 As shown, the door body 12 has a rotating shaft 14 on its side, i.e., the first side 121 of the door body, which is arranged along the direction of the side. The edge of the ventilation opening 11 has a rotating shaft seat 111 arranged opposite to it. The rotating shaft 14 is hinged to the rotating shaft seat 111. The drive mechanism 13 is connected to the rotating shaft 14.

[0069] Preferably, the rotating shaft seat 111 has a groove structure, the opening of the groove structure is in the same direction as the opening of the vent 11, and the rotating shaft 14 is rotatably disposed in the groove structure.

[0070] In this embodiment, by setting the pivot 14 on the pivot seat 111, the hinge connection between the door body 12 and the ventilation opening 11 is realized. The door body 12 can rotate around the pivot 14 as the rotation axis to realize the opening and closing of the ventilation opening 11. The structure is simple and the door body 12 is not prone to jamming during rotation.

[0071] In another embodiment of the present invention, the door 12 is slidably disposed on the ventilation opening 11. When it is necessary to open the ventilation opening 11, the door 12 is controlled to slide away from the ventilation opening 11 to open the ventilation opening 11; conversely, when it is necessary to close the ventilation opening 11, the door 12 is controlled to slide closer to the ventilation opening 11 to block the ventilation opening 11.

[0072] Specifically, the vent 11 has a slide rail extending from one end to the other, and the door 12 is slidably connected to the slide rail. A drive mechanism 13 is connected to the door 12 to drive the door 12 to slide on the slide rail, thereby opening and closing the vent 11. This configuration is relatively simple and occupies less space inside the garment processing device. The garment processing device does not need to reserve a large space for the sliding of the door 12, thus avoiding waste of internal space.

[0073] As another embodiment of the present invention, such as Figures 3 to 5As shown, the door assembly 1 also includes a housing 18 and a fan 17. The housing 18 covers the door 12 and the vent 11. The housing 18 has an opening 181 communicating with the inside and outside of the housing 18, and the fan 17 is disposed on the opening 181 for blowing gas into or drawing gas out of the housing 18.

[0074] Specifically, when the door assembly 1 is installed on the air intake system, the fan 17 is turned on to blow gas into the outer casing 18, and the vent 11 is opened. The gas inside the outer casing 18 enters the cylinder through the vent 11 to dry the inside of the cylinder. The moisture inside the cylinder is discharged through the air outlet system to prevent clothes from getting moldy.

[0075] When the door assembly 1 is installed on the air outlet system, the control vent 11 is opened, the vent 11 is connected to the inside of the outer shell 18, and the control fan 17 is used to draw gas from the outer shell 18. In other words, the fan 17 actually draws out the moisture inside the cylinder, thereby improving the moisture discharge efficiency.

[0076] In this embodiment, the air circulation efficiency inside the cylinder is effectively improved by setting up the outer casing 18 and the fan 17, preventing clothes from getting moldy. Meanwhile, the fan 17 has an adjustable speed; by adjusting the speed of the fan 17, the air circulation rate inside the cylinder can be controlled. This ensures that the inside of the cylinder remains relatively dry while achieving controllable drying efficiency. Users can adjust the speed of the fan 17 according to their actual needs. Furthermore, the fan 17 is integrated into the outer casing 18, facilitating the overall installation, disassembly, and replacement of both the fan 17 and the outer casing 17.

[0077] As another embodiment of the present invention, the vent 11 has a protrusion 183 disposed along the edge of the vent 11 and protruding outward from the edge of the vent 11. The protrusion 183 extends at least partially into the housing 18, and the door body 12 is disposed on the protrusion 183.

[0078] More specifically, the protrusion 183 is perpendicular to the plane containing the cross-section of the vent 11.

[0079] In this embodiment, by providing a protrusion 183 at the edge of the vent 11, and the protrusion 183 extending at least partially into the housing 18, the air inside the housing 18 can fully enter the vent 11, or the moisture output from the vent 11 can fully enter the housing 18, thereby improving the efficiency of gas input and output and improving the ventilation effect of the vent 11.

[0080] In one embodiment of the present invention, the protrusion 183 includes a protrusion root 182, which is connected to the edge of the vent 11. The protrusion 183 has an extension 185 extending outward from the protrusion root 182, and the housing 18 is disposed on the extension 185. Specifically, the housing 18 is sealed to the extension 185.

[0081] The outer casing 18 is disposed on the extension 185, which further increases the sealing between the outer casing 18 and the vent 11, reduces gas leakage, improves the efficiency of gas input and output, and makes the ventilation effect inside the cylinder better.

[0082] Preferably, the extension 185 is parallel to the plane containing the cross-section of the vent 11. This arrangement facilitates the fixed installation of the housing 18.

[0083] More preferably, the protrusion 183 is integrally formed with the outer shell 18. Since the door body 12 is disposed on the protrusion 183, the protrusion 183 is integrally formed with the outer shell 18, which enables the overall installation, disassembly and replacement of the outer shell 18 and the door body 12, thereby improving the efficiency of installation, disassembly and replacement.

[0084] In this invention, the protrusion 183 also includes a protrusion end, which is located away from the edge of the vent 11 and opposite to the root 182 of the protrusion. A sealing gasket 16 is provided at the end of the protrusion 183, allowing the door 12 to make sealed contact with the protrusion 183 through the sealing gasket 16. This arrangement prevents air entering the outer casing 18 from overflowing to the outside of the cylinder, thus improving the utilization rate of outside air.

[0085] Preferably, the end of the protrusion 183 has an inwardly recessed groove, and the sealing gasket 16 is engaged in the groove. The sealing gasket 16 is engaged in the groove, which simplifies the installation method and makes it less likely for the sealing gasket 16 to fall off the protrusion 183.

[0086] In another embodiment of the present invention, the drive mechanism 13 is disposed on the shell wall of the housing 18. The installation method of the drive mechanism 13 and the shell wall of the housing 18 is simple, and the drive mechanism 13 is integrated on the housing 18, which facilitates the overall installation, disassembly and replacement of the drive mechanism 13 and the housing 18.

[0087] As one embodiment of the present invention, such as Figure 4 and Figure 5 As shown, the drive mechanism 13 is disposed on the extension 185.

[0088] By setting the drive mechanism 13 on the extension 185, the drive mechanism 13 is prevented from occupying the space inside the housing 18, and the air or moisture inside the housing 18 will not damage the drive mechanism 13, thereby improving the safety of the drive mechanism 13 and extending its service life.

[0089] Preferably, the extension 185 has a mounting post 184 disposed perpendicular to the extension 185, and the drive mechanism 13 is fixedly connected to the mounting post 184.

[0090] Specifically, the drive mechanism 13 is a motor, which has a first mounting portion 131. The first mounting portion 131 extends outward from the motor housing and has a through hole. The motor is fixedly connected to the mounting post 184 through the through hole in the first mounting portion 131.

[0091] This configuration allows for quick installation of the drive mechanism 13 and the housing 18, and the installation method is simple, with good assembly stability between the drive mechanism 13 and the housing 18.

[0092] As another embodiment of the present invention, such as Figure 2 , Figure 4 and Figure 5 As shown, the door assembly 1 also includes a position sensor 15, which is disposed on the vent 11 or the door 12 and is used to detect whether the vent 11 is closed.

[0093] In this embodiment, by setting a position sensor 15, the opening and closing of the vent 11 can be detected in a timely and accurate manner, and the next operation can be executed according to the current opening and closing status of the vent 11. When the vent 11 completes the action of closing or opening under the control of the control system, the control drive mechanism 13 stops driving; when the vent 11 fails to complete the action of closing or opening for a long time, it indicates that there may be a malfunction at the vent 11, and the control clothing handling device will sound an alarm.

[0094] The position sensor 15 in this invention is a contact sensor, and the contact of the contact sensor is activated by the contact and pressure of two objects. The contact sensor is located at the edge of the vent 11, and the door 12 has a closed state in contact with it and an open state apart from it.

[0095] The door 12 rotates toward the vent 11. When the door 12 completely blocks the vent 11 and comes into contact with the contact sensor, the contact sensor sends a signal that the vent 11 is closed.

[0096] Conversely, when the door 12 changes from being in contact with the contact sensor to being separated, the contact sensor is controlled to send a signal to open the vent 11.

[0097] Alternatively, the position sensor 15 can be a proximity sensor. When the door 12 approaches the vent 11 to a set distance, the proximity sensor sends a "vent 11 closed" signal. Specifically, proximity sensors include electromagnetic, photoelectric, differential transformer, eddy current, capacitive, reed switch, and Hall effect sensors, etc.

[0098] In one embodiment of the present invention, the garment handling device includes a housing, and the housing includes an outer tubing 2 and an inner tubing. The outer tubing 2 is disposed inside the housing, and the inner tubing is disposed inside the outer tubing 2. The outer tubing 2 is used to hold washing water, and the inner tubing is used to hold garments.

[0099] The vent 11 and door assembly 1 are mounted on the outer tub 2. The drive mechanism 13 drives the door 12 to open the vent 11, allowing air from outside the outer tub 2 to enter the interior of the outer tub 2 and further into the inner tub to dry clothes. The drive mechanism 13 also drives the door 12 to close the vent 11, preventing washing water inside the outer tub 2 from splashing out through the vent 11.

[0100] Alternatively, the vent 11 and door assembly 1 are disposed on the housing, and the outer tub 2 is connected to the vent 11. Specifically, the outer tub 2 is connected to the vent 11 on the housing via a connecting pipe. The drive mechanism 13 drives the door 12 to open the vent 11, allowing air from outside the housing to enter the outer tub 2 through the vent 11 and the connecting pipe, and further into the inner tub to dry clothes. The drive mechanism 13 drives the door 12 to close the vent 11, preventing washing water inside the outer tub 2 from splashing out of the housing through the vent 11 and the connecting pipe.

[0101] As another embodiment of the present invention, the garment processing device further includes a condenser 3 disposed outside the cylinder. The condenser 3 includes a shell structure with an internal cavity, which communicates with the inside of the cylinder. The vent 11 and the door assembly 1 are disposed on the shell wall of the condenser 3 shell structure for communicating with the outside of the shell structure.

[0102] Specifically, the garment handling device includes a drying fan 4 and a drying duct 5. The inlet of the drying duct 5 is connected to the outlet of the drying fan 4. The outlet of the drying duct 5 is located at the front end of the garment handling device and is connected to the inside of the outer cylinder 2 through the window gasket 21 of the garment handling device.

[0103] The condenser 3 includes an air outlet and an air inlet. The air outlet is located at the top of the condenser and is connected to the air intake of the drying fan 4. The air inlet is located at the bottom of the condenser 3 and is opposite to the rear end of the outer cylinder 2. The air inlet is connected to the inside of the outer cylinder 2.

[0104] The condenser 3 includes a condensing air duct, which includes a main air duct and a curved transition air duct. The upper end of the main air duct is connected to the air outlet of the condenser 3, and the lower end of the main air duct is connected to the edge of the air inlet of the condenser 3 through the curved transition air duct.

[0105] Vent 11 and door assembly 1 are located on the main air duct of condenser 3. After the clothes processing device finishes dehydration, the drying fan 4 is turned on, creating a negative pressure environment inside condenser 3. Vent 11 is opened, and air from outside condenser 3 enters condenser 3 through vent 11. Under the action of drying fan 4, air enters the outer cylinder 2 through drying duct 5, drying the inside of the outer cylinder 2. At the same time, the outer cylinder 2 has an air outlet duct connected to the outside of the housing. Water droplets and moisture inside the outer cylinder 2 are discharged to the outside of the housing through the air outlet duct. This cycle ensures air circulation inside the outer cylinder 2, drying the clothes.

[0106] In this embodiment, when the clothing processing device is in the drying state, the control door assembly 1 closes the vent 11 to prevent the condenser 3 from leaking air through the vent 11 during the drying state, thereby reducing the drying efficiency of the clothes; when the clothing processing device is in the washing state, the control door assembly 1 closes the vent 11 to prevent the condenser 3 from leaking water through the vent 11 during the condensation state.

[0107] As another embodiment of the present invention, the air outlet system of the present invention connects the inside of the outer cylinder 2 and the outside of the box body so as to discharge the moisture inside the outer cylinder 2 in a timely and efficient manner.

[0108] Furthermore, a water tank 6 is installed on the housing of the garment handling device. The water tank 6 has a first pipe 61, one end of which connects to the inside of the water tank 6, and the other end connects to the inside of the outer cylinder 2. The water tank 6 also has a second pipe 62, which connects the water tank 6 to the outside of the housing. Moisture inside the outer cylinder 2 enters the water tank 6 through the first pipe 61 and is then discharged to the outside of the housing through the second pipe 62.

[0109] In this embodiment, the moisture inside the outer cylinder 2 is discharged to the outside of the box through the first pipe 61 and the second pipe 62 of the water box 6. This not only avoids mold and bacteria growth inside the outer cylinder 2, but also eliminates the need to specially set up exhaust vents on the outer cylinder 2 and the box. It can be improved on the existing clothing processing device without changing the existing structure of the clothing processing device.

[0110] In another embodiment of the present invention, a handle is provided on the housing of the garment handling device. The handle has a vent that connects to the interior of the housing. A vent 11 is provided on the outer cylinder 2, and the vent 11 is connected to the vent. Moisture inside the outer cylinder 2 is discharged to the outside of the outer cylinder 2 through the vent 11 and to the outside of the housing through the vent on the handle. Further, the vent and the vent are connected by a pipe.

[0111] In this embodiment, the moisture in the outer cylinder 2 is discharged to the outside of the box through the vent on the handle, eliminating the need for a separate exhaust device on the box, resulting in a simple structure.

[0112] like Figures 7 to 9 As shown, the present invention also provides a control method for the above-mentioned garment processing device. The garment processing device includes a control system. After dehydration is completed, the control system controls the drive mechanism 13 to drive the door 12 to open the vent 11.

[0113] After dehydration, the inside of the outer cylinder 2 is relatively humid. The ventilation port 11 is opened to introduce dry air from the outside into the outer cylinder 2, while expelling the moisture inside the outer cylinder 2. This cycle is repeated to dry the inside of the outer cylinder 2 and prevent mold and bacteria from growing inside the outer cylinder 2.

[0114] As one embodiment of the present invention, such as Figure 7 As shown, the garment processing device also includes a timing module. After dehydration, a preset timing time t0 is established; timing begins, and the timing time t is acquired; when the timing time t is greater than or equal to the preset timing time t0, the control system controls the opening of the vent 11 for ventilation. During ventilation, it is determined whether the garments in the garment processing device have been removed; if so, the vent 11 is closed.

[0115] In this embodiment, if the user does not remove the clothes within the pre-designed time t0 after the dehydration is completed, the ventilation vent 11 will be opened for ventilation to prevent the clothes from becoming moldy and breeding bacteria due to not being removed for a long time.

[0116] In another embodiment of the present invention, the garment handling device further includes a humidity sensor, which is disposed inside the outer cylinder 2 and electrically connected to the control system. Figure 8 As shown, the control method for the garment handling device includes the following steps:

[0117] After S1 completes dehydration, the preset humidity value u0 is set.

[0118] The S2 control system controls the humidity sensor to detect the humidity value u inside the outer cylinder 2;

[0119] S3 When the obtained humidity value u is greater than the preset humidity value u0, the control system controls the drive mechanism to drive the door to open the ventilation opening 11; otherwise, repeat step S2.

[0120] S4 determines whether the clothes in the clothing handling device have been removed; if yes, the control system controls the vent 11 to be closed; if no, ventilation continues until the clothes are removed.

[0121] Alternatively, step S3 is S3 * Step S4 is S4 * ,

[0122] S3 * When the acquired humidity value u is greater than the preset humidity value u0, the control system controls the drive mechanism to drive the door to open the ventilation port 11 for ventilation time t1.

[0123] S4 * Determine whether the clothes in the clothing handling device have been removed; if yes, the control system closes the vent 11; if no, repeat steps S2 to S4. * .

[0124] Preferably, the humidity value u is positively correlated with the ventilation time t1.

[0125] In this embodiment, when the humidity value inside the outer cylinder 2 reaches a preset value, the vent 11 is opened to ventilate the inside of the outer cylinder 2, preventing mold and bacteria growth inside the outer cylinder 2. When the humidity value inside the outer cylinder 2 does not reach the preset value, the vent 11 is kept closed to prevent bacteria and dust from the external environment from entering the inside of the outer cylinder 2 through the vent 11 and contaminating the clothing.

[0126] In another embodiment of the present invention, the garment handling device has a drying function. The garment handling device includes a temperature sensor, which is disposed inside the outer drum 2 and electrically connected to the control system. Figure 9 As shown, the control method for the garment handling device includes the following steps:

[0127] After dehydration is completed in S1', drying is carried out. After drying is completed, the preset temperature value T0 is set.

[0128] The S2' control system controls the temperature sensor to detect the temperature value T inside the outer cylinder;

[0129] S3' When the detected temperature value T is greater than the preset temperature value T0, the control system controls the drive mechanism 13 to drive the door 12 to open the vent 11; when the detected temperature value T is less than or equal to the preset temperature value T0, the control system controls the vent 11 to close.

[0130] In this embodiment, after drying is completed, when the internal temperature of the outer cylinder 2 is higher than the preset temperature, the ventilation port 11 is opened to accelerate the air flow inside the outer cylinder 2, quickly reduce the internal temperature of the outer cylinder 2, and reduce the cooling time inside the outer cylinder 2.

[0131] In another embodiment of the present invention, when the vent 11 is open, the position sensor 15 sends an open signal to the control system; when the vent 11 is closed, the position sensor 15 sends a close signal to the control system.

[0132] Specifically, during the process of opening the vent 11, if the control system receives an opening signal, it controls the drive mechanism to stop driving; during the process of closing the vent 11, if the control system receives a closing signal, it controls the drive mechanism to stop driving.

[0133] In this embodiment, the drive mechanism 13 is controlled by the open and close signals sent by the position sensor 15 to accurately control the opening and closing of the drive mechanism 13, thereby avoiding continuous operation of the drive mechanism, which would cause wear and tear on the drive mechanism 13 and increase the energy consumption of the drive mechanism.

[0134] In this invention, after the vent 11 is opened, the control system controls the garment processing device to execute a shaking program. The shaking program involves controlling the inner drum of the garment processing device to intermittently rotate forward and backward. During the garment shaking process, combined with the air circulation inside the drum, the drying efficiency inside the drum is greatly improved.

[0135] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
