Description

Technical Field

[0001] This invention relates to the field of clothing processing technology, and in particular to a clothing processing device. Background Technology

[0002] Clothing treatment equipment includes standalone dryers or washer-dryer combos with drying functions. Their drying principle involves using a high-temperature airflow to pass over the surface of the clothes to be dried, heating the garments and removing evaporated moisture, thus quickly drying them. Typical clothing treatment equipment only has a drying function, requiring users to iron wrinkled clothes separately. However, current clothing treatment equipment with steam generators continuously produce steam during operation and blow it into the drum. During operation, the constant contact of hot steam with the clothes softens the fibers, leaving them smooth and supple, eliminating the need for an ironing board and the tedious step of ironing.

[0003] However, existing garment processing equipment does not fix the garments to make them flat when steam ironing them. That is, the surface fibers of the garments are not stretched when exposed to steam, resulting in poor ironing effect. Summary of the Invention

[0018] Optionally, the number of exhaust ribs is at least two, and the at least two exhaust ribs are arranged at circumferential intervals along the roller.

[0019] Optionally, one end of the exhaust rib extends through the bottom of the drum to form a steam passage that communicates with the adsorption hole;

[0020] The garment processing equipment further includes an outer cylinder, a first cover, and a second cover. The outer cylinder is sleeved on the roller. The first cover and the second cover are installed at the bottom of the outer cylinder. The first cover, the second cover, and the bottom of the outer cylinder together form a first sub-air duct, a second sub-air duct, and a third sub-air duct. The control valve is installed at the intersection of the first sub-air duct, the second sub-air duct, and the third sub-air duct. The first sub-air duct constitutes part of the first air duct, the second sub-air duct constitutes part of the second air duct, and the third sub-air duct constitutes part of the main air duct.

[0026] In this invention's garment processing equipment, an adsorption structure adsorbs and fixes the garments inside the drum, and a steam generator produces steam to iron the garments. When the steam passes through the garments, the adsorption structure exerts a pulling force on the surface fibers, effectively flattening the garments.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0046] This invention proposes a garment processing device, which can take many forms, including garment drying equipment and garment washing equipment, specifically a dryer or a washer-dryer combo. Taking a dryer as an example, there are many types of dryers; taking a tumble dryer as an example, this garment processing device includes a drum 10. Garments are placed inside the drum 10. As the drum 10 rotates, the garments rotate along with it, coming into contact with flowing, high-temperature air. The high-temperature air carries away the moisture from the garments (the moisture is evaporated and carried away), thus quickly drying the garments.

[0047] Current dryers with a steam generator 30 continuously produce steam during operation and blow it into the dryer drum. During operation, the hot steam constantly contacts the clothes, softening the fibers and making them smooth and supple, eliminating the need for an ironing board and simplifying the traditional ironing process. However, existing dryers do not hold the clothes in place to ensure they are flat during steam ironing; the surface fibers are not stretched under the steam, resulting in poor ironing performance.

[0048] In embodiments of the present invention, such as Figures 1 to 4 As shown, Figure 1 This is a schematic diagram of the structure of an embodiment of the clothing processing device of the present invention; Figure 2 This is a schematic diagram of another embodiment of the clothing processing device of the present invention;

[0049] Figure 3 This is a front projection schematic diagram of an embodiment of the clothing processing device of the present invention; Figure 4 for Figure 3 A cross-sectional schematic diagram of the clothing processing equipment along the AA direction.

[0050] The garment processing device includes: a housing with an installation cavity; a roller 10 rotatably mounted in the installation cavity, the inner wall of the roller 10 having an adsorption structure 20 for adsorbing and fixing garments; and a steam generator 30 mounted in the installation cavity, the steam generator 30 having a steam outlet connected to the roller 10 for generating steam to iron the garments adsorbed and fixed by the adsorption structure 20.

[0051] In this embodiment, the housing forms the overall appearance structure of the garment processing equipment. The mounting cavity is used to install components of the garment processing equipment, and the roller 10 is installed within the mounting cavity to hold garments. The housing has a loading / unloading port communicating with the mounting cavity. The loading / unloading port can be located on the top of the housing or on one side wall in the lateral direction of the housing; there is no limitation thereto. The roller 10 has a bottom and an opening, with the opening facing the loading / unloading port. Users can put garments into or remove them from the roller 10 through the loading / unloading port. The garment processing equipment may also include a door assembly. The specific form and operation of the door assembly are not limited, as long as it allows the loading / unloading port to be opened or closed. It is understood that when the garment processing equipment is operating, the door assembly will close the loading / unloading port to prevent garments from being thrown out of the roller 10.

[0052] The adsorption structure 20 can take many forms, such as a vacuum adsorption structure 20, an electrostatic adsorption structure 20, or a mechanical adsorption structure 20. There are no restrictions here, as long as it can adsorb and fix the clothing. The force applied by the adsorption structure 20 to the clothing can flatten at least part of the clothing, meaning that at least part of the surface fibers of the clothing are stretched by the force of the adsorption structure 20. Therefore, when steam passes through the flattened portion of the clothing, the steam can produce an ironing effect, softening the surface fibers and keeping them flat, thereby improving the ironing effect.

[0053] The steam generator 30 uses thermal energy to heat water into steam. The steam generator 30 can be installed inside or outside the drum 10; there are no restrictions, as long as the steam generated by the steam generator 30 can flow into the drum 10 and pass over the clothing adhered and fixed by the adsorption structure 20. It is understood that the clothing processing equipment may also include a water tank, which is connected to the inlet of the steam generator 30, thereby providing liquid for heating the steam generator 30.

[0054] In the garment processing equipment of this invention, the garments inside the roller 10 are adsorbed and fixed by the adsorption structure 20, and then steam is generated by the steam generator 30 to iron the garments inside the roller 10. When the steam passes through the garments, the adsorption structure 20 can exert a pulling force on the surface fibers of the garments, thereby effectively flattening the garments. After the steam passes through the flattened parts of the garments, the garments are ironed smooth. Thus, the ironing effect of the garment processing equipment on the garments is improved.

[0055] For example, such as Figure 4 As shown, the roller 10 has an air inlet 11, the adsorption structure 20 includes an adsorption hole 21 formed on the inner wall of the roller 10, the air inlet 11 and the adsorption hole 21 are connected in the mounting cavity through a return air duct 40, and the steam outlet of the steam generator 30 is connected to the air inlet 11; the clothing processing equipment also includes a gas driving device 50 installed in the return air duct 40, the gas driving device 50 is used to drive air to flow from the adsorption hole 21 to the air inlet 11.

[0056] The gas drive device 50 can be a fan or an air pump, and there is no limitation on its use. The gas drive device 50 drives air from the return air duct 40 into the drum 10 through the air inlet 11, and then out of the drum 10 through the suction hole 21, thus achieving airflow circulation between the drum 10 and the return air duct 40. When the airflow from the return air duct 40 flows from the suction hole 21 to the air inlet 11, the suction hole 21 creates a negative pressure on the drum 10, thereby adsorbing the clothes onto the inner wall of the drum 10. Steam enters the drum 10 along with the airflow, passes through the clothes, and then flows into the suction hole 21, thus providing an ironing effect. Using the negative pressure generated by the return air duct 40 to adsorb and fix the clothes simplifies the adsorption process and allows the steam to effectively penetrate the clothes, improving the steam's effect. When steam ironing is not needed, the airflow generated by the gas drive device 50 can also dry the clothes.

[0057] The roller 10 has multiple adsorption holes 21, which are concentrated in a portion of the inner wall of the roller 10. This increases the adsorption area for clothing, allowing the clothing to be flattened more and improving the ironing effect. Specifically, the cross-section of the adsorption hole 21 is smaller than that of the air inlet 11, resulting in a faster airflow velocity when the air passes through the adsorption hole 21. This creates a more significant air pressure difference between the inner and outer sides of the adsorption hole 21, increasing the adsorption force on the clothing and improving the adsorption effect.

[0058] The adsorption hole 21 can be directly formed on the cylinder wall of the roller 10, or it can be formed on a protruding structure on the cylinder wall of the roller 10. For example, Figure 4 As shown, the adsorption structure 20 includes an exhaust rib 22 installed on the peripheral wall of the roller 10, the exhaust rib 22 extending along the axial direction of the roller 10, the adsorption hole 21 being opened in the exhaust rib 22; and the air outlet 12 being opened at the bottom of the roller 10.

[0059] Multiple adsorption holes 21 are distributed among the exhaust ribs 22, forming a cavity between the exhaust ribs 22 and the drum wall of the roller 10, which is connected to the return air duct 40. During ironing, the exhaust ribs 22 can lift the adsorbed clothes relative to the inner wall of the roller 10, making it easier for the clothes adsorbed by the adsorption holes 21 to come into contact with steam, thereby improving the ironing effect. During drying, the exhaust ribs 22 can also lift the clothes as the roller 10 rotates, that is, to disperse the clothes along the axial direction of the roller 10, preventing the clothes from piling up, thereby improving the drying efficiency.

[0060] Specifically, the number of exhaust ribs 22 is at least two, for example, two, three or four; at least two exhaust ribs 22 are arranged at intervals along the circumference of the roller 10, and each exhaust rib 22 is distributed with adsorption holes 21, so that multiple positions on the inner circumferential wall of the roller 10 can adsorb clothes, thereby increasing the number of clothes that can be adsorbed and fixed, thereby increasing the number of clothes that can be effectively ironed and improving ironing efficiency.

[0061] The garment handling equipment also has a drying function, and the drying and ironing functions can share the return air duct 40. For example, such as... Figure 4 and Figure 10 As shown, Figure 10 This is an exploded view of an embodiment of the garment processing device of the present invention. The roller 10 is also provided with an air outlet 12, which is connected to the air inlet 11 through the return air duct 40. The adsorption hole 21 can be opened on the peripheral wall of the roller 10, the air outlet 12 is opened on the cylinder wall of the roller 10, and the air inlet 11 is opened at the cylinder opening of the roller 10.

[0062] When the garment processing equipment is drying clothes, the drum 10 rotates, the steam generator 30 is turned off, and the gas drive device 50 drives the airflow into the drum 10 from the air inlet 11, flows through the clothes, and then flows out from the air outlet 12. The garment processing equipment may also include a heating element 51, which is installed in the return air duct 40 and located downstream of the airflow of the gas drive device 50. The heating element 51 can be a heating wire or a PCT heating element, or it can be a heat pump assembly; there are no limitations on this. When the garment processing equipment is drying clothes, the heating element 51 can be turned on to heat the airflow flowing into the drum 10. The clothes inside the drum 10 can exchange heat with the heating element 51 through the airflow to improve the drying effect of the clothes.

[0063] There can be multiple air outlets 12, which are distributed at the bottom of the drum 10. Specifically, the cross-section of the air outlet 12 is larger than that of the air inlet 11, so that the airflow entering the drum 10 can flow faster inside the drum 10, thereby optimizing the gas flow inside the drum 10 and further improving the drying efficiency of clothes.

[0064] When the garment processing equipment is ironing, the connection between the air outlet 12 and the return air duct 40 can be cut off by the valve, allowing all the steam from the steam generator 30 to flow through the adsorption hole 21. When the garment processing equipment is drying, the connection between the adsorption hole 21 and the return air duct 40 can also be cut off by the valve, allowing all the drying airflow to flow through the air outlet 12. The valve cutting off the adsorption hole 21 from the return air duct 40 and the valve cutting off the air outlet 12 from the return air duct 40 can be the same valve or different valves.

[0065] For example, such as Figure 5 and Figure 6 As shown, Figure 5 This is a rear projection schematic diagram of an embodiment of the garment processing device of the present invention; Figure 6 This is a simplified schematic diagram of the return air duct 40 in this invention. The return air duct 40 includes a main air duct 41, a first air duct 42, and a second air duct 43. The main air duct 41 is connected to the air inlet 11. The first air duct 42 connects the adsorption hole 21 to the main air duct 41. The second air duct 43 connects the air outlet 12 to the main air duct 41. The gas driving device 50 is installed in the main air duct 41. The clothing processing equipment also includes a control valve 60 installed at the intersection of the main air duct 41, the first air duct 42, and the second air duct 43. The control valve 60 is used to connect or disconnect the first air duct 42 from the main air duct 41, and to connect or disconnect the second air duct 43 from the main air duct 41.

[0066] When the garment processing equipment is ironing, steam flows out of the adsorption hole 21 from the roller 10 and enters the first air duct 42, then flows to the main air duct 41, and finally flows back to the roller 10. When the garment processing equipment is drying, the drying airflow flows out of the air outlet 12 from the roller 10 and enters the second air duct 43, then flows to the main air duct 41, and finally flows back to the roller 10. The control valve 60 controls the opening or closing of the adsorption hole 21 by controlling the connection or disconnection between the first air duct 42 and the main air duct 41, and controls the opening or closing of the air outlet 12 by controlling the connection or disconnection between the second air duct 43 and the main air duct 41. Therefore, in the ironing mode, the influence of the air outlet 12 on the ironing process can be reduced by closing the air outlet 12. In the drying mode, the influence of the adsorption hole 21 on the drying process can be reduced by closing the adsorption hole 21.

[0067] The control process of control valve 60 on the first air duct 42 and the second air duct 43 can be independent or linked. For example, ... Figure 7 and Figure 9 As shown, Figure 7 This is a schematic diagram of one working state of the control valve 60 in this invention; Figure 9 This is a schematic diagram of another working state of the control valve 60 in this invention. The control valve 60 is used to connect the first air duct 42 to the main air duct 41 while isolating the second air duct 43 from the main air duct 41; or to connect the second air duct 43 to the main air duct 41 while isolating the first air duct 42 from the main air duct 41.

[0068] The control valve 60 can switch between isolating the first air duct 42 and isolating the second air duct 43, so that only one control valve 60 is needed to simultaneously control the opening or closing of the first air duct 42 and the second air duct 43, thereby simplifying the internal structure of the garment processing equipment and simplifying the control process of the first air duct 42 and the second air duct 43.

[0069] Of course, control valve 60 can also control the first air duct 42 and the second air duct 43 to be partially open simultaneously. For example, as shown... Figure 8 As shown, Figure 8 This is a schematic diagram of another operating state of the control valve 60 in this invention. The control valve 60 is also used to control the first ventilation ratio between the first air duct 42 and the main air duct 41, and to control the second ventilation ratio between the second air duct 43 and the main air duct 41; the first ventilation ratio and the second ventilation ratio are negatively correlated.

[0070] In the ironing mode of the garment processing equipment, both the first air duct 42 and the second air duct 43 can be opened. At this time, by adjusting the ventilation ratio of the first air duct 42 and the second air duct 43, the garments near the air outlet 12 can also come into contact with steam, thereby increasing the amount of garments that can be ironed and improving the ironing efficiency of the garments.

[0071] For example, such as Figure 10 As shown, Figure 10 This is an exploded view of an embodiment of the garment processing device of the present invention. One end of the exhaust rib 22 penetrates the bottom of the drum 10 to form a steam outlet 23 communicating with the adsorption hole 21; the garment processing device also includes an outer drum 71, a first cover 72, and a second cover 73. The outer drum 71 is sleeved on the drum 10, and the first cover 72 and the second cover 73 are installed on the bottom of the outer drum 71. The first cover 72, the second cover 73, and the bottom of the outer drum 71 enclose and form a first sub-air duct 421, a second sub-air duct 431, and a third sub-air duct 411; the control valve 60 is installed on the... The intersection of the first sub-air duct 421, the second sub-air duct 431, and the third sub-air duct 411; the first sub-air duct 421 constitutes part of the first air duct 42, the second sub-air duct 431 constitutes part of the second air duct 43, and the third sub-air duct 411 constitutes part of the main air duct 41; the bottom of the outer cylinder 71 is provided with a first overflow port 711 and a second overflow port 712, the first overflow port 711 connects the first sub-air duct 421 to the steam outlet 23, and the second overflow port 712 connects the second sub-air duct 431 to the air outlet 12.

[0072] The roller 10 can rotate inside the outer cylinder 71, but the outer cylinder 71 will not rotate with the roller 10. 。The first cover 72 is opposite to the first outlet 711, and the second cover 73 partially covers the second outlet 712 and extends to communicate with the gas drive device 50. It can be seen that the first air duct 42, the second air duct 43, and the main air duct 41 converge at the bottom of the outer cylinder 71; therefore, the control valve 60 is also installed at the bottom of the outer cylinder 71. The space between the bottom of the roller 10 and the bottom of the outer cylinder 71, along with the second sub-air duct 431, together constitute the second air duct 43. Using the bottom of the outer cylinder 71 as part of the duct wall for the first air duct 42, the second air duct 43, and the main air duct 41 improves the effective utilization rate of the outer cylinder 71 and makes the duct structure of the garment processing equipment simpler and more compact.

[0073] For example, such as Figure 11 and Figure 12 As shown, Figure 12 This is a schematic diagram of the structure of a rotating block 93 according to an embodiment of the present invention. The garment processing equipment also includes a drive motor 80 and a flow passage structure 90. The flow passage structure 90 is installed between the bottom of the drum 10 and the bottom of the outer drum 71. The flow passage structure 90 includes a bottom fixing plate 91, an air duct mounting plate 92, and a rotating block 93. The bottom fixing plate 91 is fixed to the bottom of the drum 10 and is positioned to avoid the air outlet 12. The bottom fixing plate 91 extends from the steam outlet 23 to the axis of the drum 10. The bottom fixing plate 91 has a steam outlet 911 communicating with the steam outlet 23. The air duct mounting plate 92 covers the bottom fixing plate 91 to form a steam passage cavity communicating with the steam outlet 911. The air duct mounting plate 92 has an installation port 921 at one end near the axis of the roller 10, and the installation port 921 communicates with the steam passage chamber; the rotating block 93 is installed at the installation port 921 and extends into the first cover 72 through the first flow port 711; the rotating block 93 has a steam passage and a third flow port 931 and a fourth flow port 932 communicating with the steam passage, the third flow port 931 is located on the side of the rotating block 93 facing the steam passage chamber, and the fourth flow port 932 is located on the peripheral wall of the rotating block 93; the drive shaft of the drive motor 80 passes through the first cover 72 and is fixedly connected to the rotating block 93.

[0074] The steam passage cavity formed by the bottom fixing plate 91 and the air duct mounting plate 92 connects the steam passage port 23 with the rotating block 93; that is, the bottom fixing plate 91 and the air duct mounting plate 92 separate the first air duct 42 and the second air duct 43. The drive motor 80 is installed at the bottom of the outer cylinder 71 and is located outside the first cover 72. The bottom fixing plate 91, the air duct mounting plate 92, the rotating block 93 and the roller 10 can all rotate with the drive shaft of the drive motor 80.

[0075] Steam flows from the exhaust ribs 22 to the steam inlet 23 and then into the steam passage chamber, from the steam passage chamber into the rotating block 93, and finally from the peripheral wall of the rotating block 93 into the first sub-air duct 421. In other words, the exhaust ribs 22, the steam passage chamber, the inner cavity of the rotating block 93, and the first sub-air duct 421 together form the first air duct 42. Thus, the first air duct 42 can be formed by utilizing the connection structure between the drive motor 80 and the drum 10, thereby making the internal structure of the garment processing equipment simpler and more compact.

[0076] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
