Abstract
Description
Technical Field
[0001] This invention relates to the field of garment processing equipment technology, and more specifically, to a front drum assembly for garment processing equipment and garment processing equipment. Background Technology
[0002] In clothing processing equipment with drying function, the air intake structure design of the drying system directly affects drying efficiency and user experience.
[0003] In existing technologies, some solutions use an air inlet in the upper part of the door seal to guide hot air into the drum through a glass bowl. However, this structure is limited by the size of the air inlet and the shape of the glass bowl, resulting in uneven air intake and unbalanced hot air distribution, which in turn leads to problems such as prolonged drying time, low drying efficiency, or even drying failure.
[0004] Another approach involves designing a concave air guide structure on the glass bowl to direct hot air towards the lower part of the drum, attempting to extend the airflow path. However, if the concave structure is too large, it can easily cause clothes to get caught between the glass bowl and the door seal, resulting in damage. If it is too small, the air guiding effect will be insignificant, making it difficult to balance safety and drying performance.
[0005] In addition, some solutions use the front wall of the front cylinder, the air inlet seat, and the air inlet cover to form an air inlet channel. Although this shortens the flow path of the drying airflow, it still does not solve the core problem of air inlet uniformity. Hot air tends to concentrate in local areas and cannot achieve uniform coverage of the entire circumference inside the drum, affecting the stability of the drying effect.
[0006] Therefore, there is an urgent need for an improved front cylinder assembly structure to solve the technical problems of uneven air intake, low efficiency, and safety hazards in the existing technology, and to improve the user experience. Summary of the Invention
[0007] The main objective of this invention is to provide a front drum assembly and garment processing equipment to optimize the air intake structure, achieve uniform air intake, and improve drying efficiency and safety.
[0008] To address the aforementioned technical problems, this invention proposes a front drum assembly for a garment processing device, the front drum assembly comprising: The front cylinder is an open structure at the front of the outer cylinder; The air inlet is located on the open end face of the front cylinder, and its inner port is connected to the inner cylinder cavity through several circumferentially arranged air passages on the open end face of the inner cylinder. There are several air inlets, which are distributed circumferentially on the open end face of the front cylinder. The air outlet of the air duct assembly is connected to the outer port of each air inlet, and the air inlet of the air duct assembly is connected to the inner cavity of the inner cylinder.
[0009] Furthermore, the above technical solution also includes: The first air guide groove is formed on the outer end face of the opening of the front cylinder; The outer end of each air inlet is located within the first air guide groove.
[0010] In any of the above technical solutions, further, the inner wall of the first air guide trough is one or more of the following shapes: arc-shaped, spiral-shaped, and wavy.
[0011] In any of the above technical solutions, further, there are two first annular protrusions spaced apart on the outer end face of the opening of the front cylinder, and the area between the two first annular protrusions forms a first air guide groove.
[0012] In any of the above technical solutions, further comprising: An air guide cover is installed over the first air guide trough; An air inlet is provided on the first annular protrusion on the outer side, and the air inlet is connected to the air outlet of the air duct assembly through the air inlet.
[0013] In any of the above technical solutions, a second air guide groove is further provided on the inner end face of the opening of the front cylinder, and the inner end hole of each air inlet is located in the second air guide groove.
[0014] In any of the above technical solutions, further, two second annular protrusions are provided on the inner end face of the opening of the front cylinder, and the area between the two second annular protrusions forms a second air guide groove.
[0015] In any of the above technical solutions, further comprising: Adjustment components are used to adjust the opening of the air inlet to control the amount of air entering the inner cylinder.
[0016] In any of the above technical solutions, the adjusting component further includes: An adjusting plate is located on the front cylinder; And a control unit, used to control the rotation or sliding of the adjusting plate to change the area of the adjusting plate blocking the air inlet.
[0017] On the other hand, a garment processing device is also proposed, including the garment processing device front drum assembly of any of the above technical solutions.
[0018] Beneficial effects: Compared with existing technologies, 1. By distributing multiple air inlets circumferentially on the open end face of the front drum, and cooperating with the air passage at the open end of the inner drum, hot air can enter the inner drum evenly from multiple directions, avoiding the problem of hot air concentrating in a localized area in traditional structures, thus achieving uniform air delivery throughout the entire circumference. Furthermore, this structure eliminates the need for a concave air guide structure on the glass bowl, fundamentally avoiding the risk of clothing getting caught and improving safety. The overall structural design is reasonable, installation is simple, effectively shortening drying time and improving drying efficiency and user experience.
[0019] 2. By setting the first air guide trough and air guide cover, hot air can be guided to flow smoothly, reducing airflow resistance, while improving sealing performance, preventing hot air leakage, and improving heat utilization.
[0020] 3. The design of the second air guide channel further optimizes the path of hot air entering the inner drum, avoids airflow dispersion, and ensures that the hot air comes into full contact with the clothes.
[0021] 4. The adjustable components can dynamically adjust the air intake volume according to the needs of clothing load, drying mode, etc., to achieve intelligent adaptation and balance drying efficiency and energy saving. Attached Figure Description

[0030] The following embodiments will be used to provide a detailed description of the front drum assembly and the garment processing equipment of this application.
[0031] Example 1: like Figures 1-8 As shown in the figure, this embodiment proposes a garment processing device, including: a door body 1, a door seal 2, an outer tube 3, an inner tube 4, an air duct assembly 5, and a front tube assembly 6.
[0032] The inner tube 4 is rotatably disposed inside the outer tube 3 to hold clothing; several air vents 41 are provided circumferentially on the open end face of the inner tube 4, and the air vents 41 penetrate the open end face of the inner tube 4 to connect the internal cavity of the inner tube 4 with the outside.
[0033] The air duct assembly 5 includes an air duct body, a heating device, and a fan. The air outlet 51 of the air duct body is sealed to the air inlet 641 of the front cylinder assembly 6. The air inlet of the air duct body is connected to the internal cavity of the inner cylinder 4. The heating device is located inside the air duct body and is used to heat the flowing air. The fan is used to drive the air to circulate between the air duct body, the front cylinder assembly 6, and the inner cylinder 4.
[0034] The front tube assembly 6 includes: a front tube 61 and an air inlet 62. The front tube 61 is an open structure at the front of the outer tube 3, and is fixedly connected to the outer tube 3 to form the external cavity for garment processing.
[0035] Several air inlets 62 are provided on the open end face of the front cylinder 61. The air inlets 62 are distributed in the circumferential direction of the open end face of the front cylinder 61. The inner port of the air inlet 62 faces the inner cylinder 4 and is connected to the air outlet 41 of the inner cylinder 4 to ensure that the airflow can smoothly enter the interior of the inner cylinder 4 through the air inlet 62 and the air outlet 41. The outer port of the air inlet 62 faces the air duct assembly 5. The air outlet 51 of the air duct assembly 5 is connected to the outer port of each air inlet 62. The air inlet of the air duct assembly is connected to the internal cavity of the inner cylinder 4 to form a complete airflow circulation loop.
[0036] It should be noted that the distribution of the air inlets 62 can be selected as either a uniform or non-uniform circumferential distribution according to actual needs: when a uniform distribution is selected, such as... Figure 7 As shown, the circumferential spacing of each air inlet 62 is uniform, which allows the air entering the inner cylinder 4 to form a ring and diffuse evenly; when a non-uniform distribution is selected, such as Figure 8 As shown, based on the airflow characteristics inside the inner cylinder 4, the number of air inlets 62 can be increased in areas where hot air is weak, while the number of air inlets 62 can be appropriately decreased in areas where airflow is concentrated, so as to achieve targeted air replenishment and further optimize the distribution of hot air.
[0037] The design of the air inlet 62 is also flexible, and the design can be uniform, partially uniform, or completely different: the uniform design is easy to process and manufacture and is suitable for conventional drying needs; the partially uniform or completely different design can be adjusted according to the air volume requirements of different areas. For example, a large-diameter air inlet 62 can be set in an area that requires a large flow of hot air, and a small-diameter air inlet 62 can be set in an area that requires precise air delivery, so as to achieve differentiated distribution of air volume.
[0038] In this embodiment, the combination of circumferentially distributed air inlets 62 and air outlets 41 in the inner cylinder 4 overcomes the limitations of a traditional single air inlet 641, allowing hot air to enter the inner cylinder 4 from multiple directions, ultimately forming an annular airflow. This prevents hot air from concentrating in a localized area, achieving uniform airflow throughout the circumference and effectively solving the problem of uneven drying. Furthermore, the distribution and size of the air inlets 62 can be flexibly adjusted to adapt to different drying needs, improving the versatility of the structure. The overall structure is simple, requiring no additional complex air guiding components, thus reducing processing and assembly costs.
[0039] Example 2: This embodiment is a further improvement based on Embodiment 1.
[0040] like Figure 3 , Figure 5 As shown, in this embodiment, a first air guide groove 63 is provided on the outer end face of the opening of the front cylinder 61. The first air guide groove 63 extends circumferentially around the outer end face of the opening of the front cylinder 61, and the outer end holes of each air inlet 62 are located in the first air guide groove 63, so that the first air guide groove 63 can connect the outer end ports of all air inlets 62 into an integral air duct.
[0041] The inner wall of the first air guide trough 63 can be designed as one or more of the following: arc-shaped, spiral-shaped, and wave-shaped. Among them, the arc-shaped inner wall can reduce the impact and eddies of airflow in the trough, reduce airflow resistance, and allow hot air to flow smoothly. The spiral-shaped inner wall can guide the hot air to spiral forward along the trough, prolong the residence time of the hot air in the trough, and ensure that each air inlet 62 can fully enter the air. The wave-shaped inner wall can create slight disturbance of hot air in the trough through the wave structure, avoid hot air stratification, and further improve the uniformity of air intake.
[0042] Preferably, the first air guide groove 63 is formed by providing two concentric first annular protrusions 64 on the outer end face of the opening of the front cylinder 61. The two first annular protrusions 64 extend circumferentially along the opening of the front cylinder 61 and are coaxially arranged with the opening of the front cylinder 61. The annular area between the two first annular protrusions 64 forms the first air guide groove 63. This structure of the groove formed by protrusions does not require additional splicing parts and can be integrally formed with the front cylinder 61, which improves the structural strength and sealing performance, while simplifying the manufacturing process.
[0043] In this embodiment, the first air guide 63 enables the centralized distribution of hot air, ensuring that each air inlet 62 can obtain a stable and uniform air volume, and avoiding uneven drying caused by insufficient air intake of a single air inlet 62. In addition, the different shape design of the inner wall of the first air guide 63 further optimizes the air guiding effect and improves the drying performance.
[0044] Example 3: This embodiment is a further improvement based on Embodiment 2.
[0045] like Figures 1-3 As shown, in this embodiment, an air guide cover plate 65 is provided on the first air guide groove 63. The air guide cover plate 65 is sealed and connected to two first annular protrusions 64, so that the first air guide groove 63 forms a closed air guide channel, preventing hot air from leaking from the air guide groove and improving the heat utilization rate.
[0046] An air inlet 641 is provided on the first annular protrusion 64 on the outer side. The position of the air inlet 641 corresponds to the air outlet 51 of the air duct assembly 5. The air outlet 51 of the air duct assembly 5 is sealed to the air inlet 641, so that hot air can enter the first air guide groove 63 through the air inlet 641, and then be distributed to each air inlet hole 62 through the first air guide groove 63.
[0047] In this embodiment, the sealing effect of the air guide cover 65 reduces hot air leakage, improves the thermal efficiency of the drying system, and shortens the drying time. The front cylinder assembly 6 is an open structure at the front of the outer cylinder 3. The front cylinder assembly 6 forms a closed space through the cooperation of the front cylinder, the door seal 2, and the door body 1.
[0048] Example 4: This embodiment is a further improvement based on any of the above embodiments.
[0049] like Figure 6 As shown, in this embodiment, a second air guide groove 67 is also provided on the inner end face of the opening of the front cylinder 61. The second air guide groove 67 extends circumferentially around the inner end face of the opening of the front cylinder 61, and the inner end holes of each air inlet 62 are located within the second air guide groove 67. The formation of the second air guide groove 67 is similar to that of the first air guide groove 63. Two concentric second annular protrusions 66 are provided on the inner end face of the opening of the front cylinder 61. The two second annular protrusions 66 extend circumferentially along the opening of the front cylinder 61 and are coaxially arranged with the opening of the front cylinder 61. The annular area between the two second annular protrusions 66 forms the second air guide groove 67.
[0050] When hot air enters the second air guide groove 67 through the air inlet 62, the second air guide groove 67 can guide the airflow a second time, preventing the airflow from directly dissipating after being ejected from the air inlet 62, and ensuring that the airflow can be concentrated and flow towards the air outlet 41 of the inner drum 4. At the same time, the second air guide groove 67 can also buffer the airflow, reducing the impact force when the airflow enters the inner drum 4, preventing clothes from getting tangled or damaged due to excessive airflow, and achieving gentle drying.
[0051] In this embodiment, the setting of the second air guide 67 further optimizes the path of hot air entering the inner drum 4, reduces airflow divergence and loss, and ensures that hot air can efficiently enter the inner drum 4 and come into contact with the clothes; the buffering effect makes the drying process more gentle and protects the clothes from damage; it works with the first air guide 63 to form a bidirectional air guide structure, guiding the airflow from the air inlet to the air outlet, further improving the uniformity of air inlet and drying efficiency.
[0052] Example 5: This embodiment is a further improvement based on any of the above embodiments.
[0053] In this embodiment, the front cylinder assembly 6 further includes an adjustment component (not shown in the figure). The adjustment component is used to adjust the opening of the air inlet 62, thereby controlling the amount of air entering the inner cylinder 4. The adjustment component includes an adjustment plate and a control unit. The adjustment plate is disposed on the front cylinder 61 and can cover the outer or inner side of the air inlet 62. The control unit is connected to the adjustment plate and is used to control the rotation or sliding of the adjustment plate. By changing the area of the air inlet 62 blocked by the adjustment plate, the opening of the air inlet 62 is adjusted.
[0054] When the control unit controls the adjustment plate to rotate, the adjustment plate can rotate around the central axis of the opening of the front cylinder 61. The adjustment plate is provided with a through hole or notch corresponding to the air inlet 62. During the rotation, the overlapping area of the through hole or notch and the air inlet 62 changes, thereby changing the effective air inlet area of the air inlet 62.
[0055] When the control unit controls the sliding of the adjusting plate, the adjusting plate can slide circumferentially or radially along the opening of the front cylinder 61. By partially blocking the air inlet hole 62 or changing the blocking ratio of a single air inlet hole 62, the air intake volume can be adjusted. The control unit can adopt manual control or electric control mode. The electric control mode can be linked with the main control system of the garment processing equipment to automatically adjust the air intake volume according to parameters such as drying mode and garment load.
[0056] In this embodiment, the adjustment component allows for flexible adjustment of the air intake volume to adapt to different drying scenarios. For example, the air intake volume can be increased when the load of clothes is large to improve drying efficiency; the air intake volume can be reduced when the load of clothes is small to save energy; a small air volume is used for gentle drying in the fine care mode to protect the fabric of the clothes; manual or electric control methods meet the needs of different users, improving the intelligence of the product and the user experience.
[0057] Example 6: This embodiment proposes a control method for any of the above embodiments.
[0058] Specifically as follows: When the clothes drying equipment starts its drying function, the fan starts, driving the air inside the inner drum 4 into the air inlet of the air duct assembly. The air is heated into hot air after passing through the heating device inside the air duct body. Driven by the fan, the hot air flows through the air outlet 51 of the air duct assembly 5 into the air inlet 641 of the front drum assembly 6 and enters the first air guide groove 63. The first air guide groove 63 guides the hot air to be evenly distributed circumferentially, distributing the hot air to each air inlet 62. After passing through the air inlet 62, the hot air enters the second air guide groove 67. After being guided twice by the second air guide groove 67, it enters the inner drum 4 through the air outlet 41 on the open end face of the inner drum 4. The hot air comes into full contact with the clothes inside, absorbing the moisture in the clothes and achieving clothes drying. The air that has absorbed the moisture re-enters the air inlet of the air duct assembly under the action of the fan, completing one cycle.
[0059] During the drying process, the opening of the air inlet 62 can be adjusted according to actual needs by adjusting the components: When the load of clothes is heavy and there is a lot of moisture, the opening of the air inlet is increased by 62 degrees to improve the air volume and drying efficiency. When the load of clothes is light and requires delicate care, reduce the opening of the air inlet by 62 degrees to achieve gentle drying; When inconsistent drying progress is detected in different areas of the inner drum 4, targeted airflow can be adjusted through the non-uniformly distributed air inlets 62 or adjustment components to ensure uniform drying of the clothes.
[0060] Throughout the entire control process, since there is no need to set a concave air guide structure on the glass bowl of door 1, the risk of clothes getting caught is completely avoided. At the same time, through uniform air intake in all directions, optimized air guidance throughout the process, and flexible air volume adjustment, a highly efficient, uniform, and safe drying effect is achieved.
