Description

Technical Field

[0001] This application relates to the field of clothing processing technology, and in particular to a drying air path structure for a multi-tube clothing processing device and a multi-tube clothing processing device. Background Technology

[0002] Enabling all the garment processing drums in a multi-drum garment handling device to have drying functions is a key development direction for such devices. However, the equipment cost and internal space limitations of multi-drum garment handling devices typically limit the installation to only one drying unit, which is then connected to multiple garment processing drums. In existing technologies, the drying unit is often connected to the multiple garment processing drums using a pipe selection structure, which allows the user to choose which drum to connect to the drying unit.

[0003] The aforementioned technical solution of connecting the garment handling drums and the drying unit via a duct selection structure requires a relatively complex conversion structure. Furthermore, when the duct selection structure simultaneously supplies air to two or more garment handling drums, it needs to be divided into air paths connecting multiple drums, reducing the cross-sectional area of ​​each individual air path and consequently affecting the airflow rate and drying efficiency. In addition, the duct selection structure often occupies a significant amount of internal space and suffers from poor structural reliability and stability. There is an urgent need for a drying air path structure that enables simultaneous drying of two garment handling drums, is easy to control, and possesses a stable and reliable structure. Utility Model Content

[0004] This application is made in view of the aforementioned state of the prior art. The purpose of this application is to provide a drying air path structure for a multi-drum clothing processing device that enables independent control of the drying functions of the two clothing processing drums, and that the drying air path structure enables the two clothing processing drums to perform clothing drying operations simultaneously.

[0005] This application also provides a multi-tube garment processing device including the above-described drying air path structure.

[0006] This application provides a drying airflow structure for a multi-tube garment processing device. The multi-tube garment processing device includes a first tube, a second tube, and a drying device. The drying device is capable of generating a drying airflow. The drying airflow structure includes a main air duct, a first secondary air duct, and a second secondary air duct. The drying device is disposed in the main air duct, the first tube is disposed in the first secondary air duct, and the second tube is disposed in the second secondary air duct.

[0007] The first and second auxiliary air ducts are connected in parallel.

[0008] The main air duct is equipped with a main air duct on / off valve to control the opening and closing of the main air duct; the first auxiliary air duct is equipped with a first auxiliary on / off valve to control the opening and closing of the first auxiliary air duct; the second auxiliary air duct is equipped with a second auxiliary on / off valve to control the opening and closing of the second auxiliary air duct.

[0009] The main air duct includes a main air outlet duct for discharging air from the drying device and a main air inlet duct for inlet air from the drying device.

[0010] The main air duct is connected to the first and second auxiliary air ducts to form a loop, so that the drying airflow can circulate through the main air duct and either the first or second auxiliary air duct.

[0011] The first auxiliary air duct, the second auxiliary air duct, and the main air outlet duct converge at the intersection of the first air duct; the first auxiliary air duct, the second auxiliary air duct, and the main air inlet duct converge at the intersection of the second air duct.

[0012] The main air duct on / off valve is located upstream of the first air duct intersection or downstream of the second air duct intersection.

[0013] The technical solution provided in this application enables simultaneous air intake and selective individual air intake for both garment processing drums through the cooperation of on / off valves. Furthermore, unlike pipeline selection structures that separate pipelines and thus limit the drying airflow, the technical solution in this application eliminates the need for pipeline separation, thereby avoiding any impact on garment drying efficiency. In particular, the main air duct on / off valve of this drying air path structure does not need to be located at the air duct intersection, reducing the structural complexity of the on / off valve and improving the stability of the drying effect of the garment processing device.

[0014] In at least one possible implementation, the main air duct on / off valve is located in the main air outlet duct.

[0015] The first auxiliary air duct includes a first auxiliary air inlet duct for air intake of the first barrel and a first auxiliary air outlet duct for air outlet of the first barrel, and the first auxiliary on / off valve is disposed in the first auxiliary air outlet duct.

[0016] The second auxiliary air duct includes a second auxiliary air inlet duct for air intake of the second barrel and a second auxiliary air outlet duct for air outlet of the second barrel, and the second auxiliary on / off valve is disposed in the second auxiliary air outlet duct.

[0017] The above technical solution sets the auxiliary on / off valve and the main air duct on / off valve at a certain distance on the pipeline, so that the main air duct on / off valve and the auxiliary on / off valve are respectively set upstream and downstream of the clothes processing drum. This form can improve the overall reliability and stability of the drying air duct structure.

[0018] In at least one possible implementation, the main air duct on / off valve is located in the main air inlet duct.

[0019] The first auxiliary air duct includes a first auxiliary air inlet duct for air intake of the first barrel and a first auxiliary air outlet duct for air exhaust from the first barrel. The first auxiliary on / off valve is disposed in the first auxiliary air inlet duct.

[0020] The second auxiliary air duct includes a second auxiliary air inlet duct for air intake of the second barrel and a second auxiliary air outlet duct for air exhaust of the second barrel, and the second auxiliary on / off valve is disposed in the second auxiliary air inlet duct.

[0021] The above content presents a second technical solution where the secondary shut-off valve and the main air duct shut-off valve are spaced a certain distance apart on the pipeline. This solution places the main air duct shut-off valve and the secondary shut-off valve downstream and upstream of the garment processing drum, respectively. This approach can also improve the overall reliability and stability of the drying air duct structure.

[0022] In at least one possible implementation, the main air duct on / off valve, the first auxiliary on / off valve, and the second auxiliary on / off valve are one or more of pneumatic valves, hydraulic valves, and solenoid valves.

[0023] The technical solution of this application can be applied to various types of on / off valves, and several preferred types of on / off valves are given above.

[0024] In at least one possible implementation, the multi-tube garment processing device further includes a third tube, and the drying air path structure further includes a first extended air duct. The third tube is disposed in the first extended air duct, and the first extended air duct is connected to the main air duct to form a loop, so that the drying airflow can circulate through the main air duct and the first extended air duct.

[0025] The above technical content provides a drying air path structure suitable for a multi-drum clothing processing device including three clothing processing drums, which enables all three clothing processing drums to achieve clothing drying function based on a single drying device.

[0026] In at least one possible implementation, the multi-tub garment processing device further includes a fourth tub, and the drying air path structure further includes a second extended air duct. The fourth tub is disposed in the second extended air duct, and the second extended air duct is connected to the main air duct to form a loop, so that the drying airflow can circulate through the main air duct and the second extended air duct.

[0027] The above technical content further provides a drying air path structure suitable for a multi-drum clothing processing device including four clothing processing drums, which enables all four clothing processing drums to achieve clothing drying function based on a single drying device.

[0028] In at least one possible implementation, the main air duct connects the first extended air duct and the second extended air duct via an extended air duct switching valve, the extended air duct switching valve being capable of selectively connecting one of the first extended air duct and the second extended air duct to the main air duct.

[0029] The main air duct on / off valve and the extended air duct switching valve are connected in parallel in the main air duct.

[0030] The expansion air duct switching valve allows for selective flow of drying air between the third and fourth drums, based on the user's actual needs, further enhancing the user experience.

[0031] In at least one possible implementation, the first expansion duct and / or the second expansion duct is provided with an expansion duct on / off valve for controlling the opening and closing of the first expansion duct or the second expansion duct.

[0032] Installing on / off valves in the expansion ducts allows for individual control of each expansion duct. Furthermore, these on / off valves can work in conjunction with the aforementioned expansion duct switching valves to further improve the stability and reliability of pipeline on / off control.

[0033] This application also provides a multi-tub garment processing device, which includes a first tub, a second tub, and a drying device; and the aforementioned drying airflow structure for the multi-tub garment processing device.

[0034] The first bucket is located in the first secondary air duct, and the second bucket is located in the second secondary air duct.

[0035] The multi-tub clothing processing device provided in this application can achieve simultaneous or individual clothing drying operations for two clothing processing tubs by relying on the cooperation of three on-off valves without the need to install a pipeline selection switching valve. Furthermore, the on-off valves do not need to be installed at the intersection of air ducts where malfunctions are prone to occur, which can further improve the stability and reliability of the drying function of the clothing processing device.

[0036] This application also provides a multi-tub garment processing device, comprising a first tub, a second tub, a drying device, a third tub, and a fourth tub; and a drying airflow structure for the aforementioned multi-tub garment processing device, wherein the first tub is disposed in a first secondary air duct, and the second tub is disposed in a second secondary air duct.

[0037] The third barrel is disposed in the first expansion air duct, and the fourth barrel is disposed in the second expansion air duct. The first expansion air duct and the second expansion air duct are connected in parallel.

[0038] The multi-drum clothing processing device provided by the above technical solution can realize the clothing drying function of all four clothing processing drums based on a drying device, and each clothing processing drum can perform clothing drying operation individually according to the user's needs.

[0039] The drying airflow structure and the multi-drum garment processing device provided in this application control the opening and closing of the main airflow through a main airflow on / off valve installed in the main airflow duct, thereby simultaneously controlling whether the first and second drums can receive drying air. By using first and second auxiliary on / off valves respectively installed in the first and second auxiliary airflow ducts, the drying air intake of the first and second drums can be further controlled independently. Through the cooperation of the main and auxiliary on / off valves, simultaneous and independent control of the two garment processing drums can be achieved within the multi-drum garment processing device, making the functional selection of each garment processing drum more flexible and avoiding the use of complex piping structures.

[0062] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaustively describe all possible methods of this application, nor to limit the scope of this application.

[0063] This application provides a drying airflow structure (hereinafter sometimes simply referred to as "drying airflow structure") for a multi-tube garment processing device, such as... Figure 1 and Figure 2 As shown, the multi-tub garment processing device may include a first tub 10, a second tub 20, and a drying device 100. The drying device 100 is capable of generating a drying airflow, and the drying airflow structure provided in this embodiment can be used to connect the first tub 10 and the second tub 20 to the drying device 100 (especially the drying air circulation component in the drying device), respectively.

[0064] like Figure 1 and Figure 2 As shown, the drying airflow structure may include a main air duct 200, a first auxiliary air duct 310, and a second auxiliary air duct 320. The drying device 100 may be located in the main air duct 200, the first drum 10 may be located in the first auxiliary air duct 310, and the second drum 20 may be located in the second auxiliary air duct 320. The first auxiliary air duct 310 and the second auxiliary air duct 320 may be connected in parallel, meaning that the first auxiliary air duct 310 and the second auxiliary air duct 320 may be relatively independent, and the drying airflow within the first auxiliary air duct 310 and the second auxiliary air duct 320 may not affect each other.

[0065] The main air duct 200 may be equipped with a main air duct on / off valve 210 for controlling the on / off state of the main air duct 200. The first auxiliary air duct 310 may be equipped with a first auxiliary on / off valve 311 for controlling the on / off state of the first auxiliary air duct 310. The second auxiliary air duct 320 may be equipped with a second auxiliary on / off valve 321 for controlling the on / off state of the second auxiliary air duct 320. Here, the specific types of the main air duct on / off valve 210, the first auxiliary on / off valve 311, and the second auxiliary on / off valve 321 are not limited; they can be pneumatic valves, hydraulic valves, solenoid valves, etc.

[0066] The main air duct 200 and the first auxiliary air duct 310 can be connected (end to end) to form a loop, so that the drying airflow can circulate through the main air duct 200 and the first auxiliary air duct 310. The main air duct 200 and the second auxiliary air duct 320 can be connected (end to end) to form a loop, so that the drying airflow can circulate through the main air duct 200 and the second auxiliary air duct 320.

[0067] Furthermore, the main air duct 200 may include a main air outlet duct for air outlet of the drying device 100 (located downstream of the drying device 100) and a main air inlet duct for air inlet of the drying device 100 (located upstream of the drying device 100). The first secondary air duct 310 may include a first secondary air inlet duct for air inlet of the first barrel 10 (located upstream of the first barrel) and a first secondary air outlet duct for air outlet of the first barrel 10 (located downstream of the first barrel). The second secondary air duct 320 includes a second secondary air inlet duct for air inlet of the second barrel 20 (located upstream of the second barrel) and a second secondary air outlet duct for air outlet of the second barrel 20 (located downstream of the second barrel).

[0068] Preferred, such as Figure 1 As shown, the main air duct on / off valve 210 can be located in the main air outlet duct, the first auxiliary on / off valve 311 can be located in the first auxiliary air outlet duct, and the second auxiliary on / off valve 321 can be located in the second auxiliary air outlet duct. Alternatively, the main air duct on / off valve 210 can be located in the main air inlet duct, the first auxiliary on / off valve 311 can be located in the first auxiliary air inlet duct, and the second auxiliary on / off valve 321 can be located in the second auxiliary air inlet duct. It can be understood that in the above two preferred embodiments, the main air duct on / off valve 210, the first auxiliary on / off valve 311, and the second auxiliary on / off valve 321 are arranged at a certain distance from each other in the duct of the drying air path structure (interspersed on both sides of the clothes handling drum or drying device), which is more conducive to improving the reliability and stability of the drying air path structure.

[0069] Some existing technologies use duct selection structures that divide the ductwork, resulting in limited airflow for drying. However, the technical solution of this application does not require duct division and is less likely to affect the drying efficiency of clothes. In particular, the main air duct on / off valve of this drying air duct structure does not need to be set at the junction of the air ducts, which can reduce the structural complexity of the on / off valve and improve the versatility of the drying air duct structure.

[0070] like Figure 1 and Figure 2 As shown. The first auxiliary air duct 310, the second auxiliary air duct 320, and the main air outlet duct can converge at the first air duct convergence point 410. The first auxiliary air duct 310, the second auxiliary air duct 320, and the main air inlet duct can converge at the second air duct convergence point 420. Preferably, to avoid having one on / off valve control multiple air ducts simultaneously, the main air duct on / off valve 210 should not be located at the first air duct convergence point 410 or the second air duct convergence point 420. The main air duct on / off valve 210 can be located upstream of the first air duct convergence point 410 or downstream of the second air duct convergence point 420. It is understood that when the on / off valve is located at the air duct convergence point, it is necessary to simultaneously control the on / off of the first auxiliary air duct 310 and the second auxiliary air duct 320. Considering the actual structural limitations in the multi-tube garment processing device, this design will increase the design difficulty and manufacturing cost of the on / off valve.

[0071] Furthermore, such as Figure 3 As shown, the multi-tube garment processing device may further include a third tube 30, and the drying airflow structure may further include a first extended air duct 510. The third tube 30 may be disposed in the first extended air duct 510, and the first extended air duct 510 may be connected to the main air duct 200 (end-to-end) to form a loop, so that the drying airflow can circulate through the main air duct 200 and the first extended air duct 510. The multi-tube garment processing device may further include a fourth tube 40, and the drying airflow structure may further include a second extended air duct 520. The fourth tube 40 may be disposed in the second extended air duct 520, and the second extended air duct 520 may be connected to the main air duct 200 (end-to-end) to form a loop, so that the drying airflow can circulate through the main air duct 200 and the second extended air duct 520.

[0072] Preferably, the main air duct 200 can be connected to the first extended air duct 510 and the second extended air duct 520 via the extended air duct switching valve 530. The extended air duct switching valve 530 can selectively connect one of the first extended air duct 510 and the second extended air duct 520 to the main air duct 200. The main air duct on / off valve 210 can be connected in parallel with the extended air duct switching valve 530, that is, both the main air duct on / off valve 210 and the extended air duct switching valve 530 can be directly connected to the drying device without being affected by the other, thereby allowing the drying functions of the first barrel 10 and the second barrel 20 to be independently controlled and operated without affecting each other (which can be regarded as the air duct structure of the first barrel 10 and the second barrel 20 being connected in parallel with the air duct structure of the third barrel 30 and the fourth barrel 40).

[0073] It is understandable that the expansion duct switching valve 530 is a selective connection valve, meaning that the third barrel 30 and the fourth barrel 40 cannot be dried simultaneously.

[0074] Preferably, the first expansion duct 510 and / or the second expansion duct 520 are provided with expansion duct on / off valves to control the on / off state of the first expansion duct 510 or the second expansion duct 520. For example, Figure 3 Only the second expansion air duct on / off valve 521 of the second expansion air duct 520 is shown in the figure.

[0075] It is understood that in the embodiments of this application, the on / off valve can be a control structure with air duct shut-off function and is not necessarily a traditional valve body. For example, the expansion air duct on / off valve provided in the first expansion air duct 510 can also be a switching valve, which can shut off the airflow of the first expansion air duct while directing the drying airflow to other pipelines.

[0076] The drying airflow structure provided in this application can use an on / off valve to replace the pipeline selection structure in the prior art, thereby enabling independent control of the drying functions of the first and second drums. Furthermore, the drying airflow structure of this application can reliably and stably control the on / off of the drying airflow in each garment processing drum using a simple and low-cost valve body, exhibiting good versatility and application prospects.

[0077] The embodiments of this application also provide a multi-tube clothing processing device, which may include a first tube 10, a second tube 20 and a drying device 100; and the aforementioned drying air path structure for the multi-tube clothing processing device.

[0078] The first tank 10 can be installed in the first secondary air duct 310, and the second tank 20 can be installed in the second secondary air duct 320. The first tank 10 and the second tank 20 can be connected in parallel, that is, the drying function of the first tank 10 and the drying function of the second tank 20 can be controlled independently.

[0079] The multi-tube garment handling device may further include a third tube 30 and a fourth tube 40, wherein the third tube 30 may be disposed in the first expansion air duct 510 and the fourth tube 40 may be disposed in the second expansion air duct 520.

[0080] Preferably, one or more of the garment handling tubs in the multi-tub garment handling device can be multi-functional garment handling tubs that combine washing and drying functions. For example, in this embodiment, the first tub 10, the second tub 20, and the fourth tub 40 can all be combined washing and drying tubs, and the third tub 30 can be designed as a drying tub specifically for drying clothes.

[0081] The third barrel 30 can be connected in parallel with the fourth barrel 40, that is, the first extended air duct 510 and the second extended air duct 520 can be connected in parallel. Furthermore, the air duct structure of the first barrel 10 and the second barrel 20 can be connected in parallel with the air duct structure of the third barrel 30 and the fourth barrel 40.

[0082] The following is a brief description of some of the beneficial effects of the above-described embodiments of this application.

[0083] The drying airflow structure and the multi-drum garment processing device provided in this application control the opening and closing of the main airflow through a main airflow on / off valve located in the main airflow duct, thereby simultaneously controlling whether the first and second drums can receive drying air. By using first and second auxiliary on / off valves respectively located in the first and second auxiliary airflow ducts, the drying air intake of the first and second drums can be further controlled individually. Through the cooperation of the main and auxiliary on / off valves, simultaneous and individual control of the two garment processing drums can be achieved within the multi-drum garment processing device, making the functional selection of each garment processing drum more flexible and avoiding the use of complex piping structures. Furthermore, the drying airflow structure of this application can reliably and stably control the opening and closing of the drying airflow in each garment processing drum using a simple and low-cost valve body, exhibiting good versatility and application prospects.

[0084] It is understood that, in this application, when the number of parts or components is not specifically limited, the number can be one or more, where multiple refers to two or more. For cases where the number of parts or components shown in the drawings and / or described in the specification is, for example, two, three, four, etc., this specific number is generally exemplary and not restrictive, and can be understood as multiple, i.e., two or more; however, this does not mean that this application excludes the case of one.

[0085] It should be understood that the above embodiments are merely exemplary and are not intended to limit this application. Those skilled in the art can make various modifications and changes to the above embodiments under the teachings of this application without departing from the scope of this application.
