Description

Technical Field

[0001] This invention belongs to the field of clothing treatment technology, and particularly relates to a media box, a lint filter device, and clothing treatment equipment and its control method. Background Technology

[0002] As market demands become increasingly sophisticated, dryers are acquiring more and more functions. For example, some dryers now feature aromatherapy functions. When drying clothes, the aromatherapy diffuses through airflow and reaches the clothes, leaving them with a pleasant fragrance as they dry.

[0003] Existing dryers with aromatherapy functions have a constant evaporation of the fragrance medium inside the aromatherapy box, even when it is not needed. This increases the loss of the medium and makes it difficult to add fragrance to different types of clothing, thus reducing the user experience.

[0004] Therefore, there is an urgent need for a media box, a lint filter, and a garment processing equipment and control method to solve the above problems. Summary of the Invention

[0061] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0065] Example 1

[0066] like Figure 1 As shown, this embodiment provides a clothing processing device that can be used to dry clothing. The clothing processing device provided in this embodiment can be a dryer or a washer-dryer combo.

[0067] Specifically, the garment processing equipment includes a housing 700, a drum 600 disposed inside the housing 700, and a heat pump system disposed between the housing 700 and the drum 600. An air duct is formed between the inner wall of the housing 700 and the outer wall of the drum 600. The heat pump system is disposed within the air duct. An air inlet communicating with the air duct is provided at the front opening of the drum 600 in the housing 700, and an air outlet is provided at the rear end of the drum 600. The heat pump system includes a compressor 400, a condenser 300, a throttling device 800, an evaporator 200, and a fan 900. The evaporator 200, condenser 300, and fan 900 are arranged sequentially along the airflow direction. The compressor 400, condenser 300, throttling device 800, and evaporator 200 are sequentially connected by pipes to form a refrigerant circulation pipeline, which is filled with refrigerant.

[0068] When the heat pump system is running, the compressor 400 pressurizes and heats the refrigerant and sends it to the condenser 300. The high-temperature refrigerant exchanges heat with the air in the duct at the condenser 300 and is converted into a low-temperature, low-pressure gas. The low-temperature, low-pressure gas is then transported to the evaporator 200 after passing through the throttling device 800. After entering the evaporator 200, it absorbs the heat from the high-temperature, humid gas flowing across the surface of the evaporator 200, heats up, and flows back to the compressor 400, completing the refrigerant flow cycle. Meanwhile, under the action of the fan 900, the airflow in the duct enters the drum 600 through the duct outlet. When the high-temperature gas passes through the drum 600, it comes into contact with the damp clothes and becomes humid and hot gas. The humid and hot gas enters the duct through the duct inlet and is blown toward the evaporator 200. At the evaporator 200, it exchanges heat with the low-temperature cold medium. The humid and hot gas is condensed and dehumidified to form dry air. After passing through the condenser 300, the dry air exchanges heat with the high-temperature cold medium in the condenser 300 to form high-temperature dry air. The high-temperature dry air continues to flow and re-enters the drum 600 through the duct outlet, forming an airflow circulation. The air circulation carries away the moisture in the clothes, thus drying them.

[0069] In this embodiment, since the hot and humid air is condensed and cooled in the evaporator 200, forming condensate, a water collection tray 500 is also provided in the air duct to collect the condensate. In this invention, the housing 700, the drum 600, and the heat pump system can all be configured with reference to existing technology, and will not be described in detail here.

[0070] In this embodiment, to prevent or reduce lint from clothing from entering the air duct with the airflow, a lint filter 100 is installed at the air inlet of the air duct to collect the lint flowing out of the roller 600. The lint filter 100 includes a filter bracket, a filter screen mounted on the filter bracket, and a media box. The filter bracket is used to install the filter screen and to mount the lint filter 100 on the housing 700; the filter screen is used to filter and collect the lint entering the filter bracket, preventing the lint from continuing to flow with the air; the media box is used to store volatile media to achieve functions such as disinfection, sterilization, or fragrance addition to the clothing.

[0071] like Figure 2 and Figure 3 As shown, the filter support includes at least an outer filter support 2. External filter screens are provided on opposite sides of the outer filter support 2. A lint-collecting cavity is formed inside the outer filter support 2, and a filter air inlet 2111 communicating with the lint-collecting cavity is provided on the top of the outer filter support 2. During clothes drying, hot and humid air enters the lint-collecting cavity through the filter air inlet 2111, and flows into the air duct after passing through the external filter screen. The lint carried in the hot and humid air is retained in the lint-collecting cavity due to the blocking effect of the external filter screen, thus achieving the filtration and collection of lint by the lint filtering device.

[0072] The media box 4 is installed inside the external filter bracket 2. It includes a box body 41 and a sealing cover 42. The box body 41 has a receiving cavity 414 for containing the media. The box body 41 has a vent opening 412 that communicates with the receiving cavity 414. The sealing cover 42 is rotatably connected to the box body 41 to open or close the vent opening 412. The sealing cover 42 can automatically close the vent opening 412 when there is no force, and can automatically open the vent opening 412 when subjected to pressure greater than the preset external pressure.

[0073] That is, the media box 4 provided in this embodiment, by setting a sealing cover 42 rotatably connected to the box body 41, allows the sealing cover 42 to selectively open or close the ventilation opening 412. During the use of the lint filter, the ventilation opening 412 is not always open, so the ventilation opening 412 can be opened or closed according to the type of clothes to be dried, thereby ensuring targeted addition of media, improving the flexibility of media addition, and improving the user experience. At the same time, when no media is needed, the sealing cover 42 can close the ventilation opening 412, thereby preventing the media from evaporating when not in use, reducing media loss, and reducing the overall cost of the lint filter and clothes treatment device.

[0074] Preferably, to reduce the contamination of the media box 4 by lint, an inner filter screen is also provided inside the outer filter support. The inner filter screen, outer filter screen, and filter support together form the aforementioned lint receiving cavity. The inner filter screen surrounds a receiving space with a downward opening. The lint receiving cavity and the receiving space are located on the inner and outer sides of the inner filter screen, respectively, and the media box 4 is disposed in the receiving space.

[0075] Because the media box 4 is located within the accommodating space enclosed by the inner filter screen, the lint entering the lint filter device is prevented or its entry into the media box 4 is reduced due to the obstruction of the inner filter screen. This effectively prevents the media box 4 from being clogged by lint and from contaminating the media, ensuring the normal and effective use of the media and reducing the difficulty and frequency of cleaning the media box 4. At the same time, because the lint filter device has both an inner and an outer filter screen, it can effectively increase the area of ​​the filter screen and improve the effect of cleaning lint.

[0076] To facilitate the assembly and disassembly of the lint filter, preferably, such as Figure 2 and Figure 3 As shown, the filter support also includes an inner filter support 1, which includes two inner frame bodies 11 connected at the top and whose lower ends can be opened or closed relative to each other. An inner filter screen is covered on the inner filter support 1, and a media box 4 is located between the two inner frame bodies 11 and connected to them. The inner filter screen and the media box 4 are located on the inner and outer sides of the inner filter support 1, respectively. The outer filter support 2 includes two outer half-box bodies 21 that are arranged opposite to each other and spaced apart. The two outer half-box bodies 21 are located on both sides of the two inner frame bodies 11, and the lower ends of the two outer half-box bodies 21 are rotatably connected to the corresponding inner frame body 11. The top ends of the two outer half-box bodies 21 are able to be closed or closed relative to each other. Each outer half-box body 21 is provided with an outer filter screen.

[0077] This type of lint filter, by setting an inner filter support 1 and an outer filter support 2, with both the inner filter support 1 and the outer filter support 2 used to house filter screens, can increase the area of ​​the filter screen while maintaining the overall external dimensions of the lint filter, thereby increasing the filtration area and improving the lint collection capacity of the lint filter, thus reducing the cleaning frequency of the lint filter and improving the user experience. At the same time, by connecting the upper end of the inner frame 11 and the lower end of the inner frame 11 to the lower end of the outer half-box 21, the entire lint filter can be easily unfolded when cleaning the lint filter, thereby improving the cleaning convenience of the lint filter. It also facilitates the folding and assembly of the lint filter after cleaning, improving the disassembly and assembly convenience and cleaning efficiency of the lint filter.

[0078] like Figure 2 , Figure 4 and Figure 6 As shown, the opening of each outer half-box 21 faces the other outer half-box 41. Each outer half-box 21 includes an outer filter plate portion 212 for installing an outer filter screen, a box top plate 211 connected to the top of the outer filter plate portion 212, box side plates 214 connected to opposite sides of the outer filter plate portion 212, and a box bottom plate 213 connected to the bottom of the outer filter plate portion 212. The upper and lower ends of the box side plates 214 are connected to the box top plate 211 and the box bottom plate 213, respectively. The box top plate 211, outer filter plate portion 212, box side plates 214, and box bottom plate 213 together form a box space with an opening facing the other outer half-box 21.

[0079] The top plate 211 is preferably an upward-opening arc-shaped structure to accommodate the shape of the air inlet in the air duct. Each top plate 211 has several filter air inlets 2111 to ensure sufficient airflow while minimizing the size of each individual filter air inlet 2111. This improves structural strength and prevents wire debris from flying out of the wire debris filtration device through the filter air inlets 2111. Preferably, the filter air inlets 2111 are arranged in multiple rows along the circumference of the arc-shaped structure, with each row having several filter air inlets 2111 radially along the arc-shaped structure to improve processing convenience. The filter air inlets 2111 are preferably elongated holes, which facilitate the passage and settling of wire debris, ensuring sufficient collection of wire debris within the collection chamber.

[0080] The top plate 211 extends outward along the outer side of the outer filter plate 212 and the side plate 214 of the box and forms a raised edge 216. The raised edge 216 can be placed at the opening end face of the air inlet of the air duct to facilitate the installation of the lint filter device at the air inlet of the air duct.

[0081] To further facilitate the assembly and disassembly of the lint filter, each top plate 211 is provided with a pick-and-place port 218, and the pick-and-place ports 218 on the two top plates 211 are directly opposite each other. Each outer filter plate 212 has a handle 217 extending from its top end toward the other outer filter plate 212, with the two handles 217 facing each other and located within the pick-and-place port 218. The pick-and-place port 218 and the handle 217 allow users to pick up and place the lint filter at the air inlet of the duct by gripping the handle 217, improving the ease of assembly and disassembly of the lint filter.

[0082] Because the opening 218 divides the top plate 211 into two parts, reinforcing ribs 219 are provided on the inner surface of the top plate 211 to ensure its structural strength. Preferably, several reinforcing ribs 219 are spaced apart along the circumference of the top plate 211, and the reinforcing ribs 219 are located between two adjacent rows of filter inlets 2111. Furthermore, reinforcing ribs 219 are also provided at the edge of the opening 218 to further enhance the local structural strength of the outer half of the box 21 at the opening 218.

[0083] To ensure the stability of the lint filter after assembly, the upper ends of the two outer half-boxes 21 are detachably connected, and the connection method can be snap-fit, screw-fit, or plug-in. Preferably, in this embodiment, the two handles 217 have through holes 2171 extending through opposite sides of the outer half-boxes 21, and the two outer half-boxes 21 are connected by connecting rods passing through the two through holes 2171. This connection method allows the two handles 217 to adopt the same structure, simplifying the processing of the outer filter bracket 2. In other embodiments, one handle 217 may have a through hole 2171, and the other handle 217 may have a threaded hole, using a threaded connector to achieve the connection between the two.

[0084] An external vent 2121 is provided on the external filter plate portion 212, and an external filter screen is covered on the external vent 2121. Preferably, two external vents 2121 are provided at intervals along the length of the external filter plate portion 212, and the portion of the external filter plate portion 212 between the two external vents 2121 forms an external partition rib 2122. This reduces the size of a single external filter screen while ensuring the effective filtration area of ​​the external filter screen, thereby reducing the cost of the external filter screen. At the same time, it also avoids the problem that the structural strength of the external filter plate portion 212 may be compromised due to an excessively large external vent 2121. Preferably, limiting ribs 215 protrude from both sides of the external vent 2121 on the external filter plate portion 212, and the limiting ribs 215 position the external filter screen. In other embodiments, the two external vents 2121 may also be covered by the same external filter screen. The installation method of the external filter screen on the external filter plate portion 212 can refer to the prior art, and will not be described in detail here.

[0085] After the wire lint filter is assembled, the side openings of the two outer half-boxes 21 are fitted together to prevent air leakage. To facilitate the installation of the inner filter bracket 1, the upper ends of the two outer half-boxes 21 are joined, while the lower ends of the outer half-boxes 21 are relatively open, forming an installation space with a lower opening. The inner filter bracket 1 is located within this installation space. This installation space allows for increasing the length of the inner filter bracket 1 while maintaining the overall size of the outer filter bracket 2, thereby increasing the size of the inner filter screen and further increasing the filtration area. Furthermore, the installation space allows for better folding arrangements between the two components, increasing the overall length of the filter bracket 1 when unfolded.

[0086] Preferably, each side panel 214 has an installation notch 2141, which penetrates the lower end face of the side panel 214 and the side of the side panel 214 facing the other outer half-box 21. The installation notches 2141 of the two outer half-boxes 21 together form a downward-facing installation opening, which forms a lateral opening for the installation space. Both ends of the inner filter bracket 1 extend into the corresponding side installation opening and fit against the side wall of the installation opening. The installation opening can better limit the inner filter bracket 1 on the outer filter bracket 2 after the lint filter device is assembled, prevent the inner filter bracket 1 from shaking, and improve the assembly stability of the lint filter device. In other embodiments, the inner filter bracket 1 can also be completely set inside the outer filter bracket 2, that is, the side panels 214 of the two half-shells are completely fitted together.

[0087] In order to increase the contact area between the outer filter bracket 2 and the inner filter bracket 1, a raised rib is provided around the mounting notch 2141 on the inner surface of the box side plate 214, and the raised rib fits against the surface of the inner filter bracket 1.

[0088] like Figures 4-8 As shown, in this embodiment, the inner frame 11 and the outer half-box 21 are rotatably connected by a shaft connection structure 3. The shaft connection structure 3 includes a first connection structure 31 and a second connection structure 32. The first connection structure 31 has a shaft hole 314, and the second connection structure 32 has a rotating shaft portion 321, which rotatably passes through the shaft hole 314. The rotatable connection between the two is achieved through the rotational fit between the shaft and the hole, allowing for a wide range of rotation between them, and providing structural stability and a long service life. Preferably, at least two sets of shaft connection structures 3 are spaced apart along the length of the inner filter bracket 1 to improve the stability of the rotatable connection.

[0089] The first connecting structure 31 includes an upper seat 311, a semi-cylindrical part 312, and a connecting arc part 313: the upper seat 311 is connected to the outer half-box 21 or the inner frame 11; the upper end of the semi-cylindrical part 312 is connected to the side of the upper seat 311, and an arc-shaped opening 3121 is provided on the semi-cylindrical part 312; the inner surface of the connecting arc part 313 is a circular arc surface that is coaxial with the semi-cylindrical part 312 and has the same diameter, and the outer surface is a smooth curved surface. The connecting arc part 313 and the arc opening 3121 are provided in a one-to-one correspondence. The upper end of the connecting arc part 313 is connected to the upper seat 311, and the lower end of the connecting arc part 313 is connected to the lower inner surface of the semi-cylindrical part 312. The semi-cylindrical part 312 and the connecting arc part 313 together form a shaft hole 314.

[0090] The second connecting structure 32 includes a rotating shaft portion 321, a connecting rib portion 322, and an annular rib portion 323. The connecting rib portion 322 is connected to the outer half-box 21 or the inner frame 11. The connecting rib portion 322 is parallel to the axis of the rotating shaft portion 321 and connected to the outer wall surface of the rotating shaft portion 321. The annular rib portion 323 protrudes from the outer side of the rotating shaft portion 321 and is provided at intervals along the axial direction of the rotating shaft portion 321. One end of the annular rib portion 323 is perpendicularly connected to the connecting rib portion 322, and the other end of the annular rib portion 323 extends circumferentially along the rotating shaft portion 321 to the opposite side of the connecting rib portion 322 and extends upward to be flush with the upper end of the connecting rib portion 322.

[0091] The arrangement of the first connecting structure 31 and the second connecting structure 32 facilitates the opening of the upper and lower molds during processing, thereby simplifying the mold structure and improving the service life of the processing mold.

[0092] To facilitate the insertion of the rotating shaft portion 321 into the shaft hole 314, a chamfer 3211 is provided at the insertion end of the rotating shaft portion 321 to guide its entry into the shaft hole 314. Furthermore, an annular groove 3212 is provided near the insertion end of the rotating shaft portion 321, allowing the insertion end to undergo a certain deflection relative to the main structure of the second connecting structure 32. This further facilitates the insertion of the rotating shaft portion 321 into the shaft hole 314, improves the accuracy of the rotating shaft portion 321 during insertion, and enhances assembly convenience.

[0093] In this embodiment, each inner frame 11 is connected to the outer half-box 21 through two shaft connection structures 3, and the bottom ends of the inner frame 11 are respectively provided with a first connection structure 31 and a second connection structure 32, and the bottom ends of the outer half-box 413 are respectively provided with a second connection structure 32 and a first connection structure 31.

[0094] like Figure 9 and Figure 10As shown, the inner frame 11 includes an inner filter plate portion 111, on which an inner ventilation opening 1111 is provided. The inner filter screen covers the side of the inner filter support 1 facing the lint receiving cavity, thereby covering the side and top of the inner filter support 1. Preferably, two inner ventilation openings 1111 are provided at intervals along the length of the inner filter support 111 to reduce the size of a single inner ventilation opening 1111 and enhance the overall structural strength of the inner frame 11. The inner filter plate portion 111 between the two inner ventilation openings 1111 forms an inner partition rib 1112.

[0095] Preferably, a connecting plate portion 112 is connected to the lower end of the inner filter plate portion 111, and the connecting plate portion 112 is provided with the aforementioned first connecting structure 31 and second connecting structure 32. The connection plate portion 112 can reduce the thickness of the inner filter plate portion 111 while ensuring the stability of the first connecting structure 31 and the second connecting structure 32 on the inner frame 11.

[0096] The top ends of the two inner frame bodies 11 are connected by a flexible structure 12, and the flexible structure 12 is integrally formed with the inner frame bodies 11 to simplify the processing of the inner filter support 1. Specifically, the flexible structure 12 includes a connecting seat 121, which is an open ring structure with the opening facing downwards, and its two ends are respectively connected to the top ends of the two inner frame bodies 11. The thickness of the connecting seat 121 is less than the thickness of the inner frame body 11, and several connecting seats 121 are spaced apart along the length direction of the inner frame body 11.

[0097] The connecting seat 121 has a U-shaped structure with its opening facing downwards. The connecting seat 121 includes a top seat 1211 and two side seats 1212 connected to both ends of the top seat 1211. The two side seats 1212 are respectively connected to the inner frame 11. The thickness at the connection between the top seat 1211 and the side seats 1212 is less than the thickness of the rest of the structure, thereby ensuring the flexibility of the connecting seat 121 at corners and enabling relative unfolding between the top seat 1211 and the side seats 1212. In other embodiments, the connecting seat 121 can also be an arc-shaped structure.

[0098] At least two connecting seats 121 are spaced apart along the length of the inner frame 1 to ensure reliable connection between the two inner frame bodies 11. In this embodiment, three connecting seats 121 are provided, with two connecting seats 121 located at both ends of the inner frame body 11 along the length, and the other connecting seat 121 located in the middle of the inner frame body 11 along the length and directly opposite the inner partition rib 1112. Preferably, the outer surface of the side seat 1212 is smoothly connected to the outer surface of the inner filter plate 111 to reduce the sharp edges at the connection and avoid stress concentration.

[0099] More preferably, a reinforcing beam 122 connects two adjacent top seats 1211 to further enhance the overall structural strength of the inner filter bracket 1 and prevent deformation of the inner filter bracket 1 during assembly and use. Preferably, the top surface of the reinforcing beam 122 and the top surface of the top seat 1211 are on the same plane.

[0100] In other embodiments, the two inner frame bodies 11 can also be connected by a pivot structure or other hinge structure, which will not be described in detail in this embodiment.

[0101] like Figure 9 , Figure 11 and Figure 12 As shown, in this embodiment, preferably, the media box 4's body 41 includes two opposing half-box portions 411, each half-box portion 411 being connected to the corresponding inner frame 11. When the two inner frame 11 are closed, the two half-box portions 411 engage to form the aforementioned receiving cavity 414; when the two inner frame 11 are unfolded relative to each other, the two half-box portions 41 are unfolded relative to each other. This arrangement allows the half-box portions 411 to engage to form the box body 41 after the lint filter is assembled, and the two half-box portions 411 to open when the lint filter is opened, allowing the media to be removed or placed into the half-box portions 411. This enables media replacement during lint cleaning, improving the convenience of media replacement.

[0102] Preferably, the half-box portion 411 is integrally formed with the corresponding inner frame 11, thereby simplifying the processing of the filter support and improving the service life of the media box 4. In other embodiments, the half-box portion 41 can also be connected to the inner frame 11 by welding or detachable connection. The detachable connection method can be, but is not limited to, snap-fit ​​or threaded connection.

[0103] In this embodiment, each half-box 41 is an open box structure with its opening facing the other half-box 41. Preferably, the bottom surface of the half-box 41 away from the other half-box 411 is flush with the surface of the inner filter plate 111 to prevent the half-box 41 from protruding from the inner filter plate 111 in the direction towards the inner filter screen. This reduces the impact of the half-box 411 on the inner filter screen arrangement and enhances the integration of the half-box 41 with the inner frame 11. When the two half-boxes 41 are fastened together, their open end faces fit together to reduce or prevent media leakage from the joint of the two half-boxes 41.

[0104] Preferably, the lower end face of the half-box portion 411 is lower than the lower edge of the inner vent 1111 to enhance the structural strength of the connection between the inner filter plate 111 and the half-box portion 411, and improve the overall structural strength of the inner filter support 1 and the half-box portion 411.

[0105] In this embodiment, the ventilation opening 412 is located on the top of the medium box 4 so that the ventilation opening 412 is directly opposite the filter air inlet, thereby improving the convenience of the wind pressure acting on the sealing cover 42 and reducing the start-up wind pressure of the sealing cover 42.

[0106] To facilitate the installation of the sealing cap 42, the top end face of the half-box portion 411 is flat, and each half-box portion 411 has an installation opening on its top end face. The installation openings on the two half-box portions 411 together form the aforementioned ventilation opening 412. This arrangement helps to ensure that the structures of the two half-box portions 41 are consistent, thereby facilitating the processing of the half-box portions 411 and the inner filter support 1. In other embodiments, the ventilation opening 412 may be provided only on one half-box portion 411, meaning that the structures of the two half-box portions 411 are different.

[0107] Preferably, the ventilation opening 412 is a stepped opening, comprising an outer opening 4121 and an inner opening 4122. The outer opening 4121 is located on the side of the inner opening 4122 away from the inner cavity of the medium box 4. The width of the outer opening 4121 is less than the width of the inner opening 4122, and the length of the outer opening 4121 is less than or equal to the length of the inner opening 4122; or, the width of the outer opening 4121 is less than or equal to the width of the inner opening 4122, and the length of the outer opening 4121 is less than the length of the inner opening 4122. This creates a limiting step 4123 at the connection between the outer opening 4121 and the inner opening 4122. The sealing cover 42 includes an outer plate portion 4211 and an inner plate portion 4212. The outer plate portion 4211 is located on the side of the inner plate portion 4212 away from the inner cavity of the media box 4. The shape of the outer plate portion 4211 is consistent with the shape of the outer opening portion 4121, and the shape of the inner plate portion 4212 is consistent with the shape of the inner opening portion 4122. When the sealing cover 42 blocks the ventilation opening 412, the outer plate portion 4211 is located in the outer opening portion 4121, and the inner plate portion 4212 is located in the inner opening portion 4122. The end face of the inner plate portion 4212 connecting to the outer plate portion 4211 abuts against the limiting step 4123. This allows the sealing cover 42 to only flip inward when in the blocking position, preventing the sealing cover 42 from flipping outward and interfering with the structure on the inner filter support 1. At the same time, this arrangement can also better achieve the sealing of the ventilation opening 412 by the sealing cover 42.

[0108] It is understood that the length direction of the outer opening 4121 and the length direction of the inner opening 4122 are consistent with the length direction of the inner filter support 1, and the width direction of the outer opening 4121 and the width direction of the inner opening 4122 are consistent with the width direction of the inner filter support 1.

[0109] The sealing cover 42 is rotatably connected to at least one half-box portion 411 via a rotating shaft 43. Since the length dimension of the medium box 4 is larger than its width dimension, and the two sides of the medium box 4 in the width direction are flat, it is preferable that the axis of the rotating shaft 43 is aligned with the width direction of the medium box 4. This facilitates the connection between the rotating shaft 43 and the medium box 4. Furthermore, by controlling the angle at which the sealing cover 42 opens the ventilation opening 412, the effective opening size of the ventilation opening 412 can be controlled more flexibly. However, it is understood that in other embodiments, the axis of the rotating shaft 43 may also be aligned with the width direction of the medium box 4.

[0110] Furthermore, the rotating shaft 43 is fixedly connected to the sealing cover 42 and rotatably connected to the box body 41. This facilitates the integral processing of the half-box portion 411 and the inner filter support 1, ensuring the structural consistency of the two half-box portions 411. It also facilitates the assembly and disassembly of the media box 4. In this embodiment, the rotating shaft 43 and the sealing cover 42 are integrally formed to simplify processing. In other embodiments, the rotating shaft 43 and the sealing cover 42 can also be processed separately and connected together by welding, insertion, or other connection methods.

[0111] The length of the rotating shaft 43 is preferably greater than the width of the sealing cover 42, and both ends of the rotating shaft 43 protrude from both sides of the sealing cover 42 along the width direction. Each half-box portion 411 is provided with a shaft hole, and both ends of the rotating shaft 43 are respectively clearance-fitted with the corresponding shaft hole. This arrangement can improve the connection stability of the sealing cover 42 on the box body 41, and also ensure the structural consistency of the two half-box portions 411, improving the processing convenience of the half-box portions 411 and the inner filter bracket 1; at the same time, this arrangement can ensure that after the two half-box portions 411 are assembled, the two half-box portions 411 are tightly fastened by the rotating shaft 43, without the need to add an additional connecting structure to connect the two half-box portions 411.

[0112] The media cartridge 4 preferably also includes an elastic element, which is used to apply a pre-tightening force to the sealing cover 42 to block the vent opening 412. By setting the elastic force, the stability of the sealing cover 42 when blocking the vent opening 412 can be increased. At the same time, it also helps the sealing cover 42 to return to the blocking position after the external pressure is removed after the vent opening 412 is opened, thus improving the reset capability of the sealing cover 42 and improving the reliability of the media cartridge 4.

[0113] The elastic element is preferably a torsion spring 44, which is sleeved on the rotating shaft 43. One end of the torsion spring 44 is fixed relative to the housing 41, and the other end is fixed relative to the sealing cover 42. Using a torsion spring 44 reduces the space occupied by the elastic element, improves its installation convenience, and avoids interfering with the flipping of the sealing cover 42. In other embodiments, the elastic element can also be a compression spring, with one end connected to the inner surface of the sealing cover 42 and the other end connected to the inner wall of the medium box 4. When the sealing cover 42 blocks the vent opening 412, the spring is in a compressed state, thereby applying an elastic force to the sealing cover 42 to cause it to flip outward, ensuring that the sealing cover 42 tightly abuts against the limiting step 4123, thus ensuring the stability of the sealing cover 42 when blocking the vent opening 412.

[0114] In this embodiment, the media box 4 also includes a detection component for detecting whether the sealing cover 42 is in an open state. Therefore, if the detection component does not detect that the sealing cover 42 is in an open state when the sealing cover 42 meets the opening conditions, it can be determined that the media box 4 is malfunctioning, or that the fan of the garment processing equipment is malfunctioning. This allows for timely reminders to the user to troubleshoot the problem, ensuring the reliability of the media box 4 and the garment processing equipment.

[0115] It's worth noting that the volatile medium can be a scented fragrance medium. After evaporating into the drum, the fragrance medium adheres to the clothes inside, giving them a pleasant scent after drying and enhancing the user experience. The volatile medium can also be a sterilizing or disinfecting medium with antibacterial and disinfecting functions to eliminate bacteria and viruses on clothing. Alternatively, it can be a medium that meets other user requirements. Furthermore, the volatile medium can be in solid form, such as blocks or granules, and can be placed directly into the receiving box or through a perforated structure. Alternatively, the volatile medium can be liquid; in this case, absorbent blocks such as foam or sponge can be used to absorb the liquid within the receiving box.

[0116] Example 2

[0117] like Figure 13 As shown, this embodiment provides a media box 4, a lint filter device including the media box 4, and a clothing treatment device. The structure of the lint filter device and clothing treatment device provided in this embodiment is basically the same as that in Embodiment 1, except that the arrangement of the media box 4 is somewhat different. This embodiment will not describe the structure that is the same as that in Embodiment 1 again.

[0118] In this embodiment, the sealing cover 42 is disposed on the side of the box body 41, that is, at least one half of the box body 411 has a vent opening 412 on the side away from the other half of the box body 411. The sealing cover 42 is vertically disposed at the vent opening 412, and preferably the upper end of the sealing cover 42 is rotatably connected to the half of the box body 41. This arrangement allows the sealing cover 42 to naturally seal the vent opening 412 under the action of gravity, eliminating the need for a torsion spring 44 to apply force, thus reducing the cost of the media box 4. At the same time, this arrangement means that the sealing cover 42 does not need to be connected to both half of the box body 41 simultaneously, which is beneficial for the overall unfolding and folding assembly of the lint filter device.

[0119] Since the sealing cover 42 is located on the side of the medium box 4, the air pressure applied to the sealing cover 42 during the operation of the garment processing equipment is relatively small. To improve the smoothness of opening the sealing cover 42 under air pressure, preferably, a vent hole 416 is provided at the bottom of the medium box 4, and the flow area of ​​the vent hole 416 is less than one-fifth of the minimum flow area of ​​the vent opening 412. With this arrangement, although the medium may evaporate through the vent hole 416 when the sealing cover 42 blocks the vent opening 412, the small flow area of ​​the vent hole 416 can effectively suppress the evaporation rate. When air pressure is applied, the vent hole 416 promotes airflow from the vent opening 412 into the receiving cavity 414 and out through the vent hole 416, promoting airflow within the medium box 4, thereby improving the smoothness of opening the sealing cover 42. The size of the vent hole 416 can be specifically set according to the mass of the sealing cover 42 and the air pressure required to open the sealing cover 42.

[0120] In other embodiments, the sealing cap 42 can be opened under a certain wind pressure by reducing its mass; for example, the sealing cap 42 can be made of aluminum or plastic, which have a lower density. In another embodiment, a tension spring can be used to apply an upward preload to the sealing cap 42 to reduce the difficulty of opening the sealing cap 42.

[0121] Example 3

[0122] like Figure 14 As shown, this embodiment provides a media box 4, a lint filter device including the media box 4, and a clothing treatment device. The structure of the lint filter device and clothing treatment device provided in this embodiment is basically the same as that in Embodiment 1, except that the arrangement of the media box 4 is somewhat different. This embodiment will not describe the structure that is the same as that in Embodiment 1 again.

[0123] In this embodiment, the top wall of the box body 41 is provided with a ventilation opening 412, the side wall of the box body 41 is provided with an auxiliary ventilation opening, and the box body 41 is provided with an auxiliary cover 47 at the auxiliary ventilation opening. The auxiliary cover 47 can naturally block the auxiliary ventilation opening under the action of gravity, and the auxiliary cover 47 is rotatably connected to the box body 41 so that the auxiliary cover 47 can be flipped outward relative to the box body 41.

[0124] The medium box 4 provided in this embodiment is equipped with an auxiliary vent and an auxiliary cover 47. When a wind pressure greater than the starting wind pressure is applied to the sealing cover 42, the auxiliary cover 47 can be flipped outward and open the auxiliary vent under the action of the wind pressure, so that the airflow flows out of the medium box 4 from the auxiliary vent, promoting the airflow in the medium box 4 and thus improving the medium volatilization effect.

[0125] In this embodiment, the sealing cover 42 located at the top can be configured similarly to the sealing cover 42 in Embodiment 1, and will not be described again here. Furthermore, the structure restricting the auxiliary cover 47 from flipping into the medium cartridge 4 can be configured similarly to the cooperation between the sealing cover 42 and the vent opening 412, and will not be described again here.

[0126] Example 4

[0127] like Figure 15 As shown, this embodiment provides a media box 4, a lint filter device including the media box 4, and a clothing treatment device. The structure of the lint filter device and clothing treatment device provided in this embodiment is basically the same as that in Embodiment 1, except that the arrangement of the media box 4 is different. This embodiment will not describe the structure that is the same as that in Embodiment 1 again.

[0128] In this embodiment, a ventilation opening 412 is provided on one wall of the box body 41, and a ventilation channel 413 is provided on the other wall of the box body 41. The sealing cover 42 includes a first cover 421 and a second cover 422 connected together. The first cover 421 can selectively block the ventilation opening 412, and the second cover 422 is located in the receiving cavity 414. When the first cover 421 blocks the ventilation opening 412, the second cover 422 blocks the ventilation channel 413. When the first cover 421 opens the ventilation opening 412, the second cover 422 opens the ventilation channel 413.

[0129] This configuration allows airflow to enter the receiving cavity 414 through the vent opening 412 when the first cover 421 opens, and then flow out of the box 41 through the venting channel, thereby promoting airflow within the medium box 4, increasing the concentration of volatile media, and improving the evaporation effect of the medium. Furthermore, when the first cover 421 blocks the vent opening 412, the venting channel 413 is simultaneously blocked by the second cover 422, preventing the evaporation of the medium when it is not in use.

[0130] Preferably, the top of the housing 41 is provided with a ventilation opening 412, the first cover 421 blocks the ventilation opening 412 at the top, and the bottom of the medium box 4 is provided with a ventilation channel 413. This arrangement ensures that the ventilation opening 412 at the top is directly opposite the filter air inlet of the lint filter device, and that the ventilation opening 412 at the top is directly opposite the ventilation channel 413, which is more conducive to promoting airflow.

[0131] To facilitate the design of the ventilation channel 413, a protrusion 415 is provided on the inner wall of the housing 41. The protrusion 415 has a ventilation channel 413 connecting the receiving cavity 414 and the external space of the medium box 4. The protrusion 415 ensures that the airflow direction of the ventilation channel 413 is downward while allowing for flexible orientation of the air inlet of the ventilation channel 413, thus facilitating the sealing of the ventilation channel 413 by the second cover 422. In this embodiment, the air inlet of the ventilation channel 413 is horizontally oriented.

[0132] More preferably, the first cover 421 and the second cover 422 are vertically connected. When the first cover 421 blocks the ventilation opening 412, the second cover 422 is vertically positioned and fits against the side of the protrusion 415.

[0133] Furthermore, a lateral auxiliary ventilation port and an auxiliary cover 47 may be provided on the side of the box body 41, and the configuration of the auxiliary ventilation port and the auxiliary cover 47 can refer to the configuration of Embodiment 3, which will not be repeated here.

[0134] To limit the rotation angle of the top sealing cap 42 when it moves from the sealed position to the open position, a rotation limiting structure is also provided inside the medium box 4, thereby ensuring the safety of the sealing cap 42 when it is opened. In this embodiment, the rotation limiting structure is a limiting protrusion 45, which is located on opposite sides of the protrusion 415 on the second cover 422. When the second cover 422 rotates from the vertical position by a certain angle, it can abut against the limiting protrusion 45, thereby limiting the rotation of the second cover 422, that is, limiting the rotation of the top sealing cap 42. At the same time, the limiting protrusion 45 is located on the side of the second cover 422 away from the protrusion 415, which can prevent the limiting protrusion 45 from being located within the airflow range, thereby avoiding or reducing the increase in airflow resistance caused by the setting of the limiting protrusion 45, reducing airflow resistance, and reducing airflow noise.

[0135] It is understood that the above-mentioned rotation limiting structure is only an exemplary configuration, and other existing structures that can achieve rotation limiting of the sealing cover 42 are all within the protection scope of this invention.

[0136] Example 5

[0137] like Figure 16As shown, this embodiment provides a media box 4, a lint filter device including the media box 4, and a clothing treatment device. The structure of the lint filter device and clothing treatment device provided in this embodiment is basically the same as that in embodiment four, with only some differences in the arrangement of the media box 4. This embodiment will not describe the structure that is the same as that in embodiment one.

[0138] In this embodiment, the detection component 46 includes a first conductive element 461 fixedly disposed on the sealing cover 42 and a second conductive element 462 fixedly disposed on the housing 41. Both the first conductive element 461 and the second conductive element 462 are connected in series to the detection circuit. When the sealing cover 42 blocks the vent opening 412, the first conductive element 461 and the second conductive element 462 are spaced apart, meaning the detection circuit is in an open state. When the sealing cover 42 is rotated to the open position, the first conductive element 461 and the second conductive element 462 come into contact, making the detection circuit conductive. That is, this embodiment can determine whether the sealing cover 42 has opened the vent opening 412 by detecting the continuity of the detection circuit.

[0139] It is understood that in other embodiments, the detection component 46 with other detection principles and structural forms can also be used to detect the state of the sealing cover 42. For example, an angle sensor can be used to detect the opening angle of the sealing cover 42 relative to the closed state, or a proximity sensor (or micro switch) and sensing element can be used to detect whether the sealing cover 42 has rotated to a set position relative to the blocked state. The present invention will not list them all.

[0140] Preferably, the housing 41 is further provided with a limiting protrusion 45. After the sealing cover 42 is rotated to the open position, it abuts against the limiting protrusion 45 to restrict the sealing cover 42 from continuing to rotate. In this configuration, the second conductive element 462 is preferably disposed on the limiting protrusion 45. In other embodiments, the second conductive element 462 and the rotation limiting structure can be disposed separately.

[0141] It is understood that the arrangement of the box body 41 and the sealing cover 42 in this embodiment refers to the arrangement in Embodiment 4. The first conductive element 461 is disposed on the second cover 422 and is located on the side of the second cover 422 away from the boss portion 415. The first conductive element 461 is preferably configured as a plate-shaped or rod-shaped structure, and the second conductive element 462 is preferably configured as a conductive contact. However, it is understood that in other embodiments, the arrangement of the box body 41 and the sealing cover 42 can also adopt any one of the arrangements of Embodiments 1 to 3.

[0142] Example 6

[0143] like Figure 17As shown, this embodiment provides a control method for a garment processing device, which is applied to the media addition control of any one of the garment processing devices in Embodiments 1 to 5. The structure of the garment processing device will not be described in detail in this embodiment.

[0144] The control method provided in this embodiment includes the following steps:

[0145] Step S101: The fan starts running at its initial speed;

[0146] Step S102: Determine whether the current clothing processing status meets the medium addition conditions. If yes, proceed to step S103; otherwise, return to step S102.

[0147] In this embodiment, the media addition conditions include: the controller in the clothing processing equipment receives a media addition instruction sent by the user, and / or the current clothing drying stage meets the media addition requirements.

[0148] In other words, to determine whether the current processing status of the clothes meets the conditions for adding a medium, it is necessary to determine whether the current drying stage is suitable for adding a medium. For example, aromatherapy is generally added in the latter half of the drying process. When the drying process starts or the start time is short, the humidity is relatively high, so it is not suitable to add aromatherapy.

[0149] To determine whether the current garment processing status meets the conditions for adding media, the user can also choose to do so through the app, operation buttons on the garment processing device, or other means. If the user chooses to add media, then the conditions for adding media are met.

[0150] Furthermore, when users choose to add media, they can combine the detection and judgment of the drying process to further determine the specific details of media addition.

[0151] The detection and judgment of the drying process can be carried out using humidity sensors in existing technology.

[0152] Step S103: Increase the fan speed to the first preset speed.

[0153] During the drying process of clothes in the garment processing equipment, the air pressure acting on the media box is controlled by the speed of the fan. The higher the fan speed, the greater the airflow speed in the garment processing equipment, which means the greater the air pressure acting on the sealing cover. When the air pressure acting on the sealing cover is greater than or equal to the starting air pressure that causes the sealing cover to rotate and open the ventilation opening, the sealing cover opens, the media evaporates from the media box, and flows with the air into the inside of the drum, which means that the media is added to the clothes.

[0154] The first preset speed is set according to the starting air pressure required to open the sealing cover. The initial speed is less than the first preset speed, and the initial speed is specifically determined according to the type of clothing processing equipment, the model of the fan, etc. This invention does not limit the specific values ​​of the initial speed and the first preset speed.

[0155] Example 7

[0156] like Figure 18 As shown, this embodiment provides a control method for a garment processing device, and the control method provided in this embodiment is a further improvement based on the control method provided in Embodiment Six.

[0157] The control method provided in this embodiment includes the following steps:

[0158] Step S201: The fan starts running at its initial speed;

[0159] Step S202: Determine whether the current clothing processing status meets the medium addition conditions. If yes, proceed to step S203; otherwise, proceed to step S204.

[0160] Step S203: After increasing or maintaining the fan speed to the first preset speed, proceed to step S207;

[0161] Step S204: Determine whether the current fan speed is less than the first preset speed. If yes, proceed to step S206; otherwise, proceed to step S205.

[0162] Step S205: Reduce the fan speed to less than the first preset speed, and then proceed to step S207;

[0163] Step S206: Maintain the current fan speed and proceed to step S207;

[0164] Step S207: Determine whether the clothes have been dried. If yes, proceed to step S208; otherwise, return to step S202.

[0165] Step S208: The fan stops running.

[0166] Example 8

[0167] like Figure 19 As shown, this embodiment provides a control method for a garment processing device, and the control method provided in this embodiment is a further improvement based on the control method provided in Embodiment 7.

[0168] The control method provided in this embodiment includes the following steps:

[0169] Step S301: The fan starts running at its initial speed;

[0170] Step S302: Determine whether the current clothing processing status meets the medium addition conditions. If yes, proceed to step S303; otherwise, proceed to step S308.

[0171] Step S303: After increasing or maintaining the fan speed to the first preset speed, proceed to step S304;

[0172] Step S304: Determine whether the sealing cover is open. If yes, proceed to step S311; otherwise, proceed to step S305.

[0173] Step S305: Determine whether the current fan speed is less than the second preset speed. If yes, proceed to step S306; otherwise, proceed to step S307.

[0174] Step S306: Increase the fan speed to the second preset speed and return to step S304;

[0175] Step S307: Issue a fault alarm;

[0176] Step S308: Is the current fan speed less than the first preset speed? If not, proceed to step S309; ​​if yes, proceed to step S310.

[0177] Step S309: Reduce the fan speed to less than the first preset speed, and then execute step S311;

[0178] Step S310: Maintain the current fan speed and proceed to step S311;

[0179] Step S311: Determine whether the clothes have been dried. If yes, proceed to step S312; otherwise, return to step S302.

[0180] Step S312: The fan stops running.

[0181] The control method provided in this embodiment increases the fan speed to the first preset speed and then determines whether the sealing cover is open. If the sealing cover is not open, the fan speed can be increased to the second preset speed. If the sealing cover is still not open at this time, it indicates that there is a problem with the medium box or the fan. At this time, a fault alarm needs to be issued to promptly remind the user to troubleshoot the fault and ensure the normal operation of the clothing processing equipment.
