Description

Technical Field

[0001] This invention belongs to the field of clothing processing technology, and particularly relates to a clothing processing device and a drum drying control method. Background Technology

[0002] Currently, the inner drums in garment processing equipment typically come in two structures: perforated and non-perforated. Perforated inner drums have through-holes in their side walls, allowing air and water to flow between the inner and outer drums. During the drying process, hot air can flow between the inner and outer drums through these holes, thus improving drying efficiency. However, this structure also leads to stains easily remaining on the inner wall of the outer drum during washing, which can accumulate over time, breeding bacteria and producing odors, posing a hygiene risk. Non-perforated inner drums have completely sealed side walls, isolating the inner and outer drums and effectively preventing contamination of the outer drum during washing. However, this structure also has drawbacks: during the drying or drum drying stage, hot air cannot flow from the inner drum to the outer drum, resulting in insufficient coverage of the inner side of the outer drum and the outer side of the inner drum by hot air, significantly reducing drying efficiency and increasing energy consumption. Summary of the Invention

[0003] In view of this, the present invention provides a garment processing device and a drum drying control method to solve the problems of existing technologies, such as stains easily remaining on the inner wall of the outer drum during the washing process in perforated inner drums, leading to bacterial growth and odor, and hot air not being able to flow from the inner drum to the outer drum during the drying or drum drying stage in non-perforated inner drums, resulting in low drying efficiency and high energy consumption.

[0011] The present invention also provides a method for controlling the drum drying of a garment processing device, wherein the garment processing device is the garment processing device described above, and the method for controlling the drum drying includes: Determine whether the two cylindrical components need to be dried; Based on the determination results of whether the two cylindrical components need to be dried, the target drying circuit is determined; Control the connection of the target drying circuit and make the airflow flow in the target drying circuit.

[0012] Further optionally, determining the target drying circuit based on the determination result of whether the two cylinder components need to be dried includes: When one of the two cylinder assemblies needs to be dried and the other does not need to be dried, the target drying circuit is determined to be the single-sided drying circuit corresponding to the cylinder assembly that needs to be dried; When both of the drum assemblies need to be dried, continue to determine whether the two drum assemblies have finished washing; The target drying circuit is determined based on the results of the judgment on whether the two drum components have finished washing.

[0014] Compared with the prior art, the main advantages of the present invention are as follows: (1) By controlling the opening or closing of the second through hole on the lifting rib, the inner drum can switch between the two structural states of "with holes" and "without holes". During the washing or rinsing stage, the second through hole is closed to isolate the inner drum from the outer drum, completely blocking the path of washing liquid and dirt into the outer drum. This solves the problem of dirt and grime accumulating in the outer drum of traditional perforated inner drum washing machines from the structural root. During the drying or drum drying stage, the second through hole is opened to allow the inner drum to connect with the outer drum through the passage formed by the first through hole, the cavity of the lifting rib and the second through hole. The hot airflow can circulate between the inner drum and the outer drum, significantly improving the overall heat exchange efficiency and drying uniformity of the inner drum and the outer drum. This overcomes the defect of low drying efficiency of pure non-perforated inner drum, while taking into account both washing hygiene and high drying efficiency. (2) When the second through hole is opened, the inner drum and the lifting rib together form a high-efficiency hot air channel; the hot air flow can not only directly act on the clothes in the inner drum, but also quickly enter and fill the outer drum space through this channel, so that the traditional dead corner areas such as the inner wall of the outer drum and the outer wall of the inner drum can also be fully heated and dried; this structure greatly improves the heat utilization efficiency and drying speed of the entire drum assembly in the drying process, which helps to shorten the drying time and reduce energy consumption; (3) The openable and closable passage structure is integrated into the inner cylinder side wall and the inherent lifting rib component. The lifting rib itself is responsible for lifting clothes, and its cavity is cleverly used as an air duct connecting the inside and outside, realizing the multi-functionality of the component; the cover plate adopts a detachable or movable design, which makes the opening and closing operation of the passage simple and reliable. It can be manually switched by the user or easily combined with the drive mechanism to realize automatic control, improving the intelligence of the equipment and the user experience. (4) Since the inner drum can be kept closed during the washing stage, the outer drum can be kept clean for a long time, avoiding the growth of mold and dirt. This not only fundamentally improves the washing and hygiene level of clothes, but also relieves users of the tedious burden of regularly cleaning the outer drum and reduces the maintenance cost of the equipment.

Detailed Implementation

[0018] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0020] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0021] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0022] For washing machines with perforated inner drums, stains are easily left on the inner wall of the outer drum during the washing process. Long-term accumulation can breed bacteria and produce odors, causing hygiene hazards. For washing machines without perforated inner drums, hot air cannot flow from the inner drum to the outer drum during the drying or drum drying stage. As a result, the inner side of the outer drum and the outer side of the inner drum are not fully covered by hot air, which significantly reduces drying efficiency and increases energy consumption. This invention creatively provides a garment processing device, including a tubular assembly. The tubular assembly includes an inner tub, an outer tub, and lifting ribs. The inner tub is disposed inside the outer tub. An installation area is provided on the inner wall of the inner tub's sidewall, and the installation area has a first through hole. The lifting rib is disposed in the installation area, and its bottom wall and sidewall together form a cavity. The bottom wall of the lifting rib has an opening, and the sidewall of the lifting rib has a second through hole. A cover plate is provided at the second through hole for opening or closing the second through hole. When the second through hole is in the open state, the first through hole, the opening, the cavity, and the second through hole are arranged in a specific manner. The secondary connection forms a passage connecting the outer and inner cylinders; when the second through hole is closed, the passage is disconnected; by controlling the opening or closing of the second through hole on the lifting rib, the inner cylinder can switch between two structural states: "with holes" and "without holes"; during the washing or rinsing stage, the second through hole is closed, isolating the inner and outer cylinders; during the drying or drum drying stage, the second through hole is opened, allowing the inner cylinder to connect with the outer cylinder through the passage, enabling hot airflow to circulate between the inner and outer cylinders, significantly improving the overall heat exchange efficiency and drying uniformity of the inner and outer cylinders.

[0023] <Clothing Processing Equipment> like Figures 1a to 8 As shown, this embodiment provides a garment processing device, including a bobbin assembly, the bobbin assembly comprising: The inner cylinder and the outer cylinder are rotatably disposed inside the outer cylinder; the inner cylinder includes an inner cylinder sidewall 16, and the inner wall surface 161 of the inner cylinder sidewall 16 is provided with an installation area; the installation area is provided with a first through hole 162 that penetrates the inner cylinder sidewall 16. A lifting rib 2 is provided in the installation area. The lifting rib 2 includes a bottom wall 21 and a side wall 22, which together form a cavity 23. The bottom wall 21 is located near the inner wall surface 161 and has an opening 24. The side wall 22 has a second through hole 25. A detachable or movable cover plate 3 is provided at the second through hole 25 for opening or closing the second through hole 25. When the second through hole 25 is in the open state, the first through hole 162, the opening 24, the cavity 23 and the second through hole 25 are connected in sequence to form a passage, which connects the outer cylinder and the inner cylinder; that is, the inner cylinder and the lifting rib 2 together constitute a perforated inner cylinder, which is connected to the outer cylinder. When the second through hole 25 is closed, the passage is disconnected; that is, the inner cylinder, the lifting rib 2 and the cover plate 3 together form a non-perforated inner cylinder, and the non-perforated inner cylinder and the outer cylinder are not connected. The passage can be connected or disconnected by opening or closing the second through hole 25.

[0024] Furthermore, there are multiple installation areas and multiple lifting ribs 2. The multiple installation areas are arranged sequentially at intervals along the circumference of the inner cylinder, and the multiple lifting ribs 2 are arranged one-to-one in the multiple installation areas. By opening or closing the second through hole 25 of the lifting rib 2 at different positions, the inner cylinder and the outer cylinder can be connected through the passage at different positions; In this way, the following technical effects can be achieved: (1) By setting multiple independently controllable opening and closing passages around the inner cylinder, different passages can be selectively opened according to the program settings during the drying process; allowing hot airflow to enter the outer cylinder from multiple directions and in different areas, breaking the airflow concentration or short-circuiting phenomenon that may be caused by a single passage; this design can drive the hot airflow to form a more complex and more complete three-dimensional circulation between the inner and outer cylinders, significantly reducing drying dead corners, ensuring uniform and efficient drying in all areas of the inner cylinder, and avoiding the problems of local overheating or incomplete drying; (2) By programming the opening and closing sequence and combination mode of multiple channels, dynamic management of the drying process can be achieved. For example, in the early stage, more channels can be opened to quickly increase the overall temperature and dissipate moisture. In the later stage, the combination of channels can be adjusted to carry out gentle drying or balance humidity. This flexible control strategy makes the heat energy distribution more reasonable and reduces ineffective heat loss, thereby improving the drying quality and helping to further optimize the overall energy efficiency. (3) Multiple lifting ribs 2 with passage function are evenly distributed along the circumference of the inner cylinder, which not only satisfies the technical purpose of multi-directional ventilation, but also makes the dynamic balance of the inner cylinder better.

[0025] Preferably, the installation area and the lifting rib 2 are each provided with three, and the second through hole 25 of any one of the three lifting ribs 2 can be opened or closed; Multiple second through holes 25 are provided, and the multiple second through holes 25 are spaced apart in the length and width directions of the lifting rib sidewall 22. The cover plate 3 can open or close the multiple second through holes 25 as a whole. The cover plate 3 is detachably mounted on the side wall 22 of the lifting rib. When the cover plate 3 is placed over the second through hole 25, the second through hole 25 is in a closed state; when the cover plate 3 is removed from the side wall 22 of the lifting rib, the second through hole 25 is in an open state. Specifically, the bottom wall 21 of the lifting rib and the inner wall surface 161 of the inner cylinder side wall 16 are sealed together (by sealing ring or sealant), and the cover plate 3 and the side wall 22 of the lifting rib are connected by a snap-fit ​​structure.

[0026] The following describes the drying circuit that constitutes the inner and outer drying cylinders. The outer cylinder is provided with an air inlet 151 and an air outlet 152. The air inlet 151 is used to deliver airflow into the inner cylinder, and the air outlet 152 is used to discharge the airflow from the outer cylinder. The garment processing equipment also includes a drying duct 4, which connects an air inlet 151 and an air outlet 152. When the second through hole 25 is in the open state, the inner cylinder, passage, outer cylinder and drying air duct 4 are connected in sequence to form a single-sided drying circuit, which is used to make the airflow circulate between the individual cylinder assembly and the drying air duct 4 and dry the inner cylinder and outer cylinder of the cylinder assembly.

[0027] In this way, the following technical effects can be achieved: (1) By setting an outer cylinder with an air inlet 151 and an air outlet 152 and a drying air duct 4 connecting the two, when the second through hole 25 is opened, the airflow can circulate in a complete single-sided loop of “inner cylinder → passage → outer cylinder → drying air duct 4 → inner cylinder”; this closed-loop design strictly confines the hot air within the target cylinder assembly and its dedicated air duct, forming a highly integrated single drying unit, which greatly reduces the loss of heat to the outside of the equipment or non-target areas, thereby significantly improving the thermal energy utilization rate and the overall thermodynamic efficiency of the drying system; (2) The single-sided drying circuit enables the hot airflow to flow through and act on specific cylinder components (including its inner and outer cylinders) in an orderly and concentrated manner; the airflow circulates repeatedly in this closed circuit, which can continuously and uniformly heat and dehumidify the inner and outer cylinders; this directional and concentrated drying method overcomes the problem of uneven temperature and reduced efficiency caused by the diversion of hot air between multiple chambers.

[0028] Furthermore, there are two cylindrical body assemblies, which are arranged side by side in the horizontal direction; The drying air duct 4 includes a main air duct 43, two air inlets and two air outlets. The main air duct 43 has two main air outlets and two main air inlets. One end of each of the two air inlets is connected to the two main air outlets, and the other end of each air inlet is connected to the air inlets 151 of the two outer cylinders. One end of each of the two air outlets is connected to the two main air inlets, and the other end of each air outlet is connected to the air outlets 152 of the two outer cylinders. By controlling the opening or closing of the two main air duct outlets, the connection or disconnection between the main air duct 43 and the corresponding air inlet duct can be controlled; by controlling the opening or closing of the two main air duct inlets, the connection or disconnection between the main air duct 43 and the corresponding air outlet duct can be controlled. The main air duct 43 is used to heat and dehumidify the airflow and provide power for the airflow to circulate.

[0029] The garment processing equipment also includes a two-phase box, two phases, a compressor, and a fan. The two-phase box contains two phases, and the two-phase box and the fan are connected to form a main air duct 43. The two phases include an evaporator and a condenser. The evaporator is used to dehumidify the airflow, the condenser is used to heat the airflow, and the fan is used to provide power for the airflow to circulate. The compressor, evaporator, and condenser are connected through refrigerant pipelines to form a refrigerant circulation loop. When the fan is running, the airflow circulates in the drying circuit. When the airflow flows through the evaporator, the evaporator dehumidifies the airflow; when the airflow flows through the condenser, the condenser heats the airflow; when the airflow flows through the outer cylinder, it dries the outer cylinder; and when the airflow flows through the inner cylinder, it dries the inner cylinder.

[0030] Specifically, the air inlet 151 and the air outlet 152 are offset from each other in the axial direction of the outer cylinder; the air inlet 151 is close to the opening of the outer cylinder and faces the opening of the inner cylinder, and the airflow discharged from the air inlet 151 can directly enter the inner cylinder; the air outlet 152 is close to the bottom of the outer cylinder, and the airflow in the outer cylinder can be discharged through the air outlet 152. The two main air duct outlets include a first main air duct outlet 4321 and a second main air duct outlet 4322, and the two air inlets include a first air inlet duct 411 and a second air inlet duct 412. The first air inlet duct 411 and the first main air duct outlet 4321 are correspondingly arranged, and the second air inlet duct 412 and the second main air duct outlet 4322 are correspondingly arranged. The air outlet end of the main air duct 43 is provided with a rotatable first baffle 441, which has a first working position, a second working position and a third working position. When the first baffle 441 is in the first working position, the first baffle 441 opens the first main air duct outlet 4321 and closes the second main air duct outlet 4322. The main air duct 43 and the first air inlet duct 411 are connected through the first main air duct outlet 4321, and the main air duct 43 and the second air inlet duct 412 are disconnected. When the first baffle 441 is in the second working position, the first baffle 441 opens the second main air duct outlet 4322 and closes the first main air duct outlet 4321. The main air duct 43 and the second air inlet duct 412 are connected through the second main air duct outlet 4322, and the main air duct 43 and the first air inlet duct 411 are disconnected. When the first baffle 441 is in the third working position, the first baffle 441 opens the first main air duct outlet 4321 and the second main air duct outlet 4322. The main air duct 43 and the first air inlet duct 411 are connected through the first main air duct outlet 4321, and the main air duct 43 and the second air inlet duct 412 are connected through the second main air duct outlet 4322. The two main air duct inlets include a first main air duct inlet 4311 and a second main air duct inlet 4312, and the two air outlets include a first air outlet 421 and a second air outlet 422. The first air outlet 421 and the first main air duct inlet 4311 are respectively arranged, and the second air outlet 422 and the second main air duct inlet 4312 are respectively arranged. The air inlet end of the main air duct 43 is provided with a rotatable second baffle 442, and the second baffle 442 is provided with a fourth working position, a fifth working position and a sixth working position. When the second baffle 442 is in the fourth working position, the second baffle 442 opens the first main air duct inlet 4311 and closes the second main air duct inlet 4312. The main air duct 43 and the first air outlet duct 421 are connected through the first main air duct inlet 4311, and the main air duct 43 and the second air outlet duct 422 are disconnected. When the second baffle 442 is in the fifth working position, the second baffle 442 opens the second main air duct inlet 4312 and closes the first main air duct inlet 4311. The main air duct 43 and the second air outlet duct 422 are connected through the second main air duct inlet 4312, and the main air duct 43 and the first air outlet duct 421 are disconnected. When the second baffle 442 is in the sixth working position, both the first main air duct inlet 4311 and the second main air duct inlet 4312 are opened. The main air duct 43 and the first air outlet duct 421 are connected through the first main air duct inlet 4311, and the main air duct 43 and the second air outlet duct 422 are connected through the second main air duct inlet 4312.

[0031] The following describes the structure required for the connection between the two outer tubes. Each outer tube is provided with a vent 153. The garment processing equipment also includes an inter-tube air duct 51, which connects the vents 153 of the two outer tubes. Airflow in one outer tube can enter the other outer tube through the inter-tube air duct 51. The vent 153 is used to deliver airflow into the outer tube. That is, when the second through hole 25 is closed, airflow in the outer tube can enter the inner tube through the opening of the inner tube. By controlling the connection or disconnection of the inter-tube air duct 51, the connection or disconnection of the two outer tubes can be controlled. Furthermore, the inter-tube air duct 51 is provided with a rotatable third baffle 52, and controlling the rotation of the third baffle 52 can connect or disconnect the inter-tube air duct 51.

[0032] The following description addresses the case where a drying circuit is formed between two cylindrical components, namely the first cylindrical component and the second cylindrical component. The outer cylinder, air inlet duct, air outlet duct, inner cylinder, and passageway of the first cylindrical component are respectively the first outer cylinder 11, the first air inlet duct 411, the first air outlet duct 421, the first inner cylinder 13, and the first passageway. The outer cylinder, air inlet duct, air outlet duct, inner cylinder, and passageway of the second cylindrical component are respectively the second outer cylinder 12, the second air inlet duct 412, the second air outlet duct 422, the second inner cylinder 14, and the second passageway. The main air duct 43, the first air inlet duct 411, the first inner cylinder 13, the first passage, the first outer cylinder 11, the inter-cylinder air duct 51, the second outer cylinder 12, and the second air outlet duct 422 are sequentially connected to form a first double-sided drying circuit. This circuit allows airflow to circulate between the first outer cylinder 11, the first inner cylinder 13, the inter-cylinder air duct 51, the second outer cylinder 12, and the main air duct 43, thereby drying the first outer cylinder 11, the first inner cylinder 13, and the second outer cylinder 12. The airflow circulates in the first double-sided drying circuit, and combined with the rotation of the first inner cylinder 13, it can achieve comprehensive and thorough drying of the first outer cylinder 11 and the first inner cylinder 13, while also preheating the second outer cylinder 12, which helps to improve the efficiency of drying the second inner cylinder 14. The main air duct 43, the second air inlet duct 412, the second inner cylinder 14, the second passage, the second outer cylinder 12, the inter-cylinder air duct 51, the first outer cylinder 11, and the first air outlet duct 421 are sequentially connected to form a second double-sided drying circuit. This circuit allows airflow to circulate between the second outer cylinder 12, the second inner cylinder 14, the inter-cylinder air duct 51, the first outer cylinder 11, and the main air duct 43, thereby drying the second outer cylinder 12, the second inner cylinder 14, and the first outer cylinder 11. The airflow circulates in the second double-sided drying circuit, and combined with the rotation of the second inner cylinder 14, it can achieve comprehensive and thorough drying of the second outer cylinder 12 and the second inner cylinder 14, while also preheating the first outer cylinder 11, which helps to improve the efficiency of drying the first inner cylinder 13. The main air duct 43, the first air inlet duct 411, the first inner cylinder 13, the first passage, the first outer cylinder 11, the inter-cylinder air duct 51, the second outer cylinder 12, the second inner cylinder 14, the second passage and the second air outlet duct 422 are connected in sequence to form a third double-sided drying circuit.

The third and fourth double-sided drying circuits are used to circulate the airflow between the first outer cylinder 11, the first inner cylinder 13, the inter-cylinder air duct 51, the second outer cylinder 12, the second inner cylinder 14, and the main air duct 43, and to dry the first outer cylinder 11, the first inner cylinder 13, the second outer cylinder 12, and the second inner cylinder 14. The airflow circulates in the third and fourth double-sided drying circuits, and combined with the rotation of the first inner cylinder 13 and the second inner cylinder 14, it can achieve comprehensive and thorough drying of the first outer cylinder 11, the first inner cylinder 13, the second outer cylinder 12, and the second inner cylinder 14.

[0033] In this way, the following technical effects can be achieved: (1) By controlling the opening and closing of the main air duct outlet / main air duct inlet and the on / off of the inter-cylinder air duct 51, the system can flexibly switch between a variety of predefined drying circuit modes, including the first double-sided drying circuit, the second double-sided drying circuit, the third double-sided drying circuit, and the fourth double-sided drying circuit. Users or programs can select the most economical drying mode according to the drying needs of the two cylinder components. For example, when only one cylinder component needs to be thoroughly dried, a single-sided drying circuit can be used, or when two cylinder components need to be dried, the most suitable double-sided drying circuit can be selected, realizing full-scenario coverage from "independent drying", "auxiliary preheating / drying" to "simultaneous thorough drying". (2) Multiple double-sided loop modes provide a physical basis for the efficient reuse and distribution of thermal energy. For example, in the first or second double-sided drying loop, the residual heat of the hot air that has completed the main drying task can be guided to another outer cylinder for preheating or auxiliary drying after it flows out of the first inner cylinder 13, thus realizing the step utilization of thermal energy. In the third or fourth double-sided drying loop, the hot air passes through the inner and outer spaces of the two cylinder components in an orderly manner, and completes the drying of all areas in a single cycle, avoiding the loss of air duct switching and the energy consumption of repeated heating caused by establishing separate cycles for the two cylinder components. This design significantly improves the overall energy efficiency of the multi-cylinder system under complex tasks. (3) By constructing a predetermined path through which airflow flows sequentially through the inner and outer spaces of different cylindrical components, the system can force hot air to sweep the key areas of the two cylindrical components in a directional and sequential manner. This controlled airflow organization method effectively avoids the airflow short-circuiting or uneven distribution problems that may occur when multiple spaces are ventilated in parallel, ensuring that both cylindrical components can obtain a uniform and sufficient drying effect.
