Description

Technical Field

[0001] This invention belongs to the field of washing machines, and more specifically, relates to a clothing handling device. Background Technology

[0002] Clothing processing devices typically consist of two clothing processing units, each with its own independent drainage channel. In existing technology, these channels are combined via a T-junction before being discharged through a single drain pipe. Because the inlets and outlets of the T-junction are directly interconnected, the mutual interference of water flow can cause drainage problems in both devices when both are draining simultaneously. Furthermore, when one device is draining independently, water can easily flow back into the other. Additionally, the existing T-junction drains lack anti-backflow mechanisms, making backflow a common problem.

[0003] For example, Chinese Patent Application No. 200780049680.4 discloses a clothing processing machine, including: a clothing processing device, a second clothing processing module, and a drainage system. The drain outlet of the first clothing processing module is connected to the first drain pipe of the drainage system, and the drain outlet of the second clothing processing module is connected to the second drain pipe of the drainage system. The drainage system also includes a three-way pipe, which has a first interface, a second interface, and a third interface that are interconnected. The first interface is connected to the first drain pipe, the second interface is connected to the second drain pipe, and the third interface is connected to the main drain pipe of the drainage system. Since the first interface, the second interface, and the third interface of this confluence unit are interconnected, the water discharged from the first clothing processing module and the water discharged from the second clothing processing module are collected inside the three-way pipe and then discharged into the main drain pipe through the third interface. If the drain pipes of two garment processing units drain water at the same time, the water flow may affect each other, causing the drainage of each drain pipe to be obstructed. If only the drain pipe of one garment processing unit is used for drainage, sewage may flow back into the drain pipe of the other garment processing unit, contaminating the other garment processing unit. Furthermore, the third interface of the tee pipe is not equipped with a check valve, which may cause water to flow back into the tee pipe.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. The present invention provides a clothing treatment device with a drainage transfer pipe fitting that can prevent water from flowing back into the drainage channel.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] This invention provides a garment processing device, comprising:

[0008] The device comprises a first garment processing device, a second garment processing device, and a drainage transfer pipe fitting; the drainage transfer pipe fitting includes a transfer pipe body, which has two inlets and one outlet, and the two inlets are respectively connected to the drainage outlets of the first garment processing device and the second garment processing device; the transfer pipe body is provided with a second drainage channel and a first drainage channel connecting the outlet and different inlets, and at least one drainage channel is equipped with a backflow prevention mechanism.

[0009] In the above scheme, by installing a backflow prevention mechanism in at least one drainage channel, water can be prevented from flowing back into the drainage channel.

[0010] Furthermore, the first garment processing device is located above the second garment processing device, and the drainage adapter is installed between the first garment processing device and the second garment processing device.

[0011] By installing a drainage adapter with two drainage channels between the first and second garment processing devices, when the two garment processing devices drain water simultaneously, it is possible to avoid the drainage problems caused by the mutual influence of water flow between the two garment processing devices. When one garment processing device drains water alone, it is possible to prevent water from flowing back into the other garment processing device.

[0012] Furthermore, the garment handling device includes a housing;

[0013] The housing includes a front panel disposed at the front of the first garment processing device, the front panel covering the first garment processing device and extending toward the direction of the second garment processing device;

[0014] The housing also includes a support structure connected to the front panel, located between the first garment processing device and the second garment processing device, for supporting the drainage transfer pipe fitting.

[0015] Furthermore, the support structure includes a support beam;

[0016] The support beam extends forward and backward on the side wall of the front panel, located between the first and second garment processing devices, and is connected to the drainage transfer pipe fitting.

[0017] Preferably, the support beam extends forward and backward on the side wall of one side of the front panel, and the drainage connection pipe is connected to the support surface of the support beam near the first clothing processing equipment.

[0018] Furthermore, the transfer pipe body has a drainage chamber, which is connected to the outlet, and the two inlets are respectively connected to the drainage chamber through drainage channels;

[0019] The anti-reverse mechanism is installed at the position where the drainage channel and the drainage chamber communicate;

[0020] Preferably, the transfer pipe body is a hollow pipe structure with an axially extending baffle inside, dividing the pipe into two drainage channels.

[0021] The partition is provided with a mounting part at one end near the drainage chamber, and the anti-reverse mechanism is installed on the mounting part.

[0022] Furthermore, the transfer pipe body includes a first drainage channel;

[0023] The first drainage channel extends along the axial direction of the transfer pipe body, with one end closed and the other end connected to the drainage chamber through the first drainage port.

[0024] The side wall of the transfer pipe body is provided with a first water inlet, which is connected to the first drainage channel;

[0025] Preferably, the first drainage channel is located on the side of the support beam near the center of the clothing handling device;

[0026] The first water inlet is located on the side wall of the transfer pipe body near the center of the clothing processing device and is connected to the drain outlet of the second clothing processing device.

[0027] Furthermore, the transfer pipe body includes a second drainage channel;

[0028] The second drainage channel extends along the axial direction of the transfer pipe body, with one end opening as the second water inlet and the other end communicating with the drainage chamber through the second drainage outlet;

[0029] Preferably, the second drainage channel is located on the side of the support beam away from the center of the clothing handling device;

[0030] The second water inlet is located near the front panel and is connected to the drain outlet of the first clothing processing device.

[0031] Furthermore, the first garment processing device includes a buffer tube;

[0032] The drain outlet of the first garment processing device is connected to the first drain pipe, and the buffer pipe is disposed between the first drain pipe and the second inlet of the adapter body;

[0033] Preferably, the buffer tube includes a first longitudinal tube;

[0034] One end of the first longitudinal pipe is connected to the second water inlet, and the other end extends along the axial direction of the transfer pipe body.

[0035] Furthermore, the buffer tube also includes a transition tube and a second longitudinal tube connected in sequence to the first longitudinal tube, wherein the central axis of the second longitudinal tube is arranged parallel to the central axis of the first longitudinal tube.

[0036] In the above solution, by setting up a buffer pipe, the impact force of the water flowing out of the drain outlet of the first clothing processing equipment on the drainage transfer pipe fitting can be reduced; in addition, the buffer pipe can also play a role in avoiding impact.

[0037] Furthermore, the first garment processing device has a drum-type structure, and the second garment processing device has a drawer-type structure;

[0038] Preferably, the first garment processing device uses a bottom drainage method for drainage, while the second garment processing device uses an top drainage method for drainage.

[0039] In the above solution, the first garment processing device of the present invention uses a bottom drainage method for drainage, and the second garment processing device uses an top drainage method for drainage. When the second garment processing device has a drawer-type structure, it can avoid occupying too much space inside the second garment processing device, and the drain pipe will not be bent when the drawer is pulled out, thus affecting the drainage efficiency.

[0040] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0041] The present invention provides a clothing treatment device, which can prevent water from flowing back into the drainage channel by installing a backflow prevention mechanism in the drainage channel of the drainage adapter fitting;

[0042] The present invention provides a clothing processing device, which provides a drainage transfer pipe with two drainage channels between a first clothing processing device and a second clothing processing device. When the two clothing processing devices drain water at the same time, the drainage of each clothing processing device can be avoided due to the mutual influence of water flow. When one clothing processing device drains water alone, water can be prevented from flowing back into the other clothing processing device.

[0043] The present invention provides a clothing processing device. The first clothing processing device uses a bottom drainage method for drainage, and the second clothing processing device uses a top drainage method for drainage. When the second clothing processing device has a drawer-type structure, it can avoid occupying too much space inside the second clothing processing device, and the drain pipe will not be bent when the drawer is pulled out, thus not affecting the drainage efficiency.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0057] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0058] like Figures 1 to 3 As shown, the present invention provides a clothing processing device, including: a first clothing processing device 10, a second clothing processing device 20, and a drainage adapter 34. The drainage adapter 34 includes an adapter body 341, which has two inlets and one outlet. The two inlets are respectively connected to the drain outlets of the first clothing processing device 10 and the second clothing processing device 20. The adapter body 341 is provided with a second drainage channel 3411 and a first drainage channel 3412 that connect the outlet to different inlets. At least one drainage channel is equipped with a backflow preventer 344.

[0059] Specifically, the two water inlets are connected to the drain outlets of the first garment processing device 10 and the second garment processing device 20 via the first drain pipe 31 and the second drain pipe 32, respectively. By installing a backflow prevention mechanism 344 in at least one drain channel, water can be prevented from flowing back into the drain channel.

[0060] In some embodiments, the first garment processing device 10 is located above the second garment processing device 20, and the drain pipe fitting 341 is installed between the first garment processing device 10 and the second garment processing device 20.

[0061] By installing a drainage adapter with two drainage channels between the first and second garment processing devices, when the two garment processing devices drain water simultaneously, it is possible to avoid the drainage problems caused by the mutual influence of water flow between the two garment processing devices. When one garment processing device drains water alone, it is possible to prevent water from flowing back into the other garment processing device.

[0062] In some embodiments, the garment processing device 100 includes a housing; the housing includes a front panel 101 disposed at the front of the first garment processing device 10, the front panel 101 covering the first garment processing device 10 and extending toward the second garment processing device 20;

[0063] The housing also includes a support structure connected to the front panel 101, located between the first garment processing device 10 and the second garment processing device 20, for supporting the drainage transfer pipe 341.

[0064] Furthermore, the support structure includes a support beam 102;

[0065] The support beam 102 extends forward and backward on the side wall of the front panel 101, located between the first garment processing device 10 and the second garment processing device 20, and is connected to the drainage transfer pipe fitting 34.

[0066] Preferably, the support beam 102 extends forward and backward on the side wall of one side of the front panel 101, and the drainage connection pipe 34 is connected to the support surface of the support beam 102 near the first clothing processing device 10.

[0067] More preferably, the bottom of the housing has a base, and four vertical beams extend vertically from the four corners of the base. The bottom of each vertical beam is in contact with or fixed to the base. A support beam is vertically connected between two vertical beams on the same side of the base. The support beam is located above the second garment processing device. A drainage adapter is installed on the support beam near the front panel mounting part.

[0068] Specifically, the drainage adapter fitting and the support beam are installed by riveting.

[0069] In some embodiments, the housing further includes a rear panel disposed at the rear of the first garment processing device and the second garment processing device. An opening is provided on the rear panel between the first garment processing device and the second garment processing device for installing a main drain pipe at the outlet of the drain adapter fitting.

[0070] Furthermore, the opening direction of the drainage chamber 343 is the same as the opening direction of the total drainage outlet formed by the first drainage outlet and the second drainage outlet. A groove 3432 is formed between the inner peripheral wall of the drainage chamber 343 and the outer peripheral wall of the transfer pipe body 341 for installing the main drainage pipe.

[0071] The outer peripheral wall of the drainage chamber 343 is provided with a fixing part for fixing the drainage adapter 34 to the rear plate;

[0072] Preferably, the fixing part includes at least two fixing lugs 3431 disposed on the outer peripheral wall of the drainage chamber 343. The fixing lugs 3431 protrude radially along the drainage chamber 343. The fixing lugs 3431 are provided with fixing holes. The opening of the rear panel is provided with a mating hole (not shown) in the circumferential direction. The fixing hole and the mating hole are mated together and the drainage adapter is fixed to the rear panel through a connector.

[0073] Preferably, the fixing hole can be a threaded hole, and the connector can be a screw.

[0074] Specifically, the fixing lug 3431 has a semi-cylindrical structure, and two semi-cylindrical fixing lugs 3431 are symmetrically arranged on the outer periphery of the drainage chamber 343. The fixing lug 3431 is provided with fixing holes. When the drainage adapter 34 is installed on the rear panel, the rear panel is provided with mating holes that match the threaded holes along the circumference of the opening. Screws pass through the mating holes and are fixedly connected to the threaded holes on the fixing lugs 3431.

[0075] Understandably, the shape and number of the fixing lugs 3431 can be arbitrarily selected. A triangular fixing lug can be chosen, or three, four, or more fixing lugs can be selected. As the number of fixing lugs increases, the fixing effect of the drainage adapter fitting also increases. This prevents water from the outlet of the drainage adapter fitting from flowing into the device and damaging other internal components during prolonged use if the drainage adapter fitting is not securely fixed.

[0076] Understandably, the fixing structure on the drainage chamber of the drainage adapter can also adopt a snap-fit ​​structure to fix the drainage adapter to the rear plate.

[0077] Furthermore, the main body 341 of the transfer pipe has a drainage chamber 343, which is connected to the water outlet, and the two water inlets are respectively connected to the drainage chamber 343 through drainage channels;

[0078] The anti-reverse mechanism 344 is installed at the position where the drainage channel and the drainage chamber 343 are connected;

[0079] Preferably, the transfer pipe body 341 is a hollow pipe structure with an axially extending baffle 342 inside, which divides the pipe into two drainage channels.

[0080] The partition 342 is provided with a mounting part at one end near the drainage chamber, and the anti-reverse mechanism 344 is mounted on the mounting part.

[0081] Specifically, the transfer pipe body 341 is a hollow pipe structure with an axially extending baffle 342 inside, which divides the pipe into two drainage channels; one end of the drainage channel is closed, its inlet is located on the side wall, and the other end is the drain outlet; one end of the other drainage channel is the inlet, and the other end is the drain outlet; at least one drainage channel has a backflow preventer 344 at its drain outlet.

[0082] By setting up a partition, when two drainage channels are draining water at the same time, the water flow in each drainage channel will not affect each other due to the obstruction of the partition, thus avoiding poor drainage in each drainage channel.

[0083] Preferably, the partition is a planar or arc-shaped plate structure.

[0084] In some embodiments, the diameter of the second inlet is larger than the diameter of the first inlet.

[0085] Preferably, a check valve is also provided at the end of the first water inlet.

[0086] Because the two inlets have different diameters, different diameter drain pipes can be selected and connected to the drain adapter pipe according to the actual use process, making it suitable for various drainage scenarios.

[0087] In some embodiments, the partition 342 has a mounting portion at one end near the drainage chamber 343, and the anti-reverse mechanism 343 is mounted on the mounting portion.

[0088] It is understandable that when the drain outlets of each drainage channel are not located on the same side of the transfer pipe body, each drainage channel has an installation part at the end of the drain outlet for installing a backflow prevention mechanism.

[0089] As another implementation, when the drain outlets of each drainage channel are located on the same side of the transfer pipe body, the second drain outlet and the first drain outlet of the second drainage channel are located on the same side of the transfer pipe body. In this case, an installation part can be provided at the end of the partition between each drainage channel near the drainage chamber for installing a backflow prevention mechanism.

[0090] Preferably, the mounting portion is disposed on the end face of the partition near the drainage chamber.

[0091] The mounting part can be circumferentially arranged at one end of the partition near the drainage chamber, or it can be arranged on the end face near the drainage chamber.

[0092] Specifically, the mounting part includes a mounting protrusion 3421, which is disposed on the end face of the partition near the drainage chamber.

[0093] The anti-reverse mechanism is provided with a mounting hole that mates with the mounting protrusion, and the anti-reverse mechanism is mounted on the mounting protrusion;

[0094] Preferably, the check valve mechanism is a check valve plate.

[0095] As one implementation, when the check valve plate is circular in shape, since the drain outlets of each drain channel are located on the same side of the transfer pipe body, a circular check valve plate can be installed at the main drain outlet. In this case, the mounting protrusion can be set to at least one.

[0096] Preferably, the mounting protrusion has a cylindrical structure.

[0097] As another implementation scheme, such as Figure 6 As shown, when the check valve plate is semi-circular in shape, since the drain outlets of each drain channel are located on the same side of the transfer pipe body, a check valve plate can be installed at each drain outlet. In this case, the limiting part includes at least two mounting protrusions.

[0098] Preferably, the mounting protrusion has a cylindrical structure.

[0099] Understandably, a drain pump can be installed at the outlet to drain the water from each drain channel within the drain pipe fitting.

[0100] Furthermore, the transfer pipe body 341 includes a first drainage channel 3412;

[0101] The first drainage channel 3412 extends along the axial direction of the adapter body 341, with one end closed and the other end connected to the drainage chamber 343 through the first drainage port 34122.

[0102] The side wall of the transfer pipe body is provided with a first water inlet, which is connected to the first drainage channel;

[0103] Preferably, the first drainage channel is located on the side of the support beam near the center of the clothing handling device;

[0104] The first water inlet is located on the side wall of the transfer pipe body near the center of the clothing processing device and is connected to the drain outlet of the second clothing processing device.

[0105] By setting the first water inlet in a position close to the front panel 101, the second drain pipe, which is conveniently connected to the drain outlet of the second clothing processing device, can be directly connected to the first water inlet, reducing the accumulation of the second drain pipe during installation.

[0106] Furthermore, the transfer pipe body 341 includes a second drainage channel 3411;

[0107] The second drainage channel 3411 extends along the axial direction of the adapter body 341, with one end opening as the second water inlet 34111 and the other end communicating with the drainage chamber 343 through the second drain outlet 34112.

[0108] Preferably, the second drainage channel 3411 is located on the side of the support beam 102 away from the center of the clothing handling device 100;

[0109] The second water inlet 34111 is located near the front panel 101 and is connected to the drain outlet of the first clothing processing device.

[0110] By setting the second water inlet 34111 in a position close to the front panel 101, the first drain pipe, which is conveniently connected to the drain outlet of the first clothing processing device, can be directly connected to the second water inlet, reducing the accumulation of the first drain pipe during installation.

[0111] In some embodiments, the adapter pipe body includes a first pipe section with an axially extending baffle inside; a second pipe section, one end of which is connected to the outlet, and the other end of which extends axially along the first pipe section and is connected to the outer periphery of the first pipe section; an annular boss 3433 is provided circumferentially on one end of the first pipe section near the second pipe section, and the check valve plate is disposed inside the annular boss 3433.

[0112] By placing the check valve plate inside the annular boss 3433, it can further support the check valve plate.

[0113] In some embodiments, the check valve includes a check valve body 3441, which is mounted on the drain outlet and matches the drain outlet;

[0114] A connecting plate 3442 is radially connected to one end of the check valve plate body 3441, and the mounting hole is provided on the connecting plate 3442.

[0115] During installation, the check valve disc body is directly installed inside the annular boss, and the mounting protrusion is inserted into the mounting hole of the connecting plate radially connected to one end of the check valve disc body.

[0116] Preferably, the mounting protrusion and the mounting hole are interference fit.

[0117] The interference fit design prevents the check valve plate from detaching during use, ensuring a more secure installation.

[0118] In some implementations, such as Figure 3 As shown, the drain outlet of the first clothing processing device 10 is connected to the second inlet 34111 of the second drainage channel 3411 through the first drain pipe 31;

[0119] Furthermore, the first garment processing device 10 includes a buffer tube 36;

[0120] The drain outlet of the first clothing processing device 10 is connected to the first drain pipe 31, and the buffer pipe 36 is disposed between the first drain pipe 31 and the second inlet 34111 of the adapter pipe body 341.

[0121] Preferably, the buffer tube 36 includes a first longitudinal tube 361;

[0122] One end of the first longitudinal pipe 361 is connected to the second water inlet 34111, and the other end extends along the axial direction of the transfer pipe body 341.

[0123] Furthermore, the buffer tube 36 also includes a transition tube 362 and a second longitudinal tube 363 connected in sequence to the first longitudinal tube 361, wherein the central axis of the second longitudinal tube 363 is arranged parallel to the central axis of the first longitudinal tube 361.

[0124] In the above solution, by setting a buffer pipe with multiple bends and extensions between the first drain pipe and the drain transfer fitting, the water discharged from the first drain pipe can change direction in multiple stages before flowing into the drain transfer fitting, thereby reducing the impact force of the water flow on the drain transfer fitting; in addition, the buffer pipe can also play a role in avoiding obstacles.

[0125] Furthermore, the first garment processing device 10 has a drum-type structure, and the second garment processing device 20 has a drawer-type structure;

[0126] Specifically, the housing shown has two openings on one side wall, an upper opening and a lower opening. A roller assembly is installed in the upper opening, and a drawer is inserted into or pulled out of the housing in the lower opening.

[0127] The clothing processing device of the present invention is a composite clothing processing device. The first clothing processing device is a drum-type structure, and the second clothing processing device is a drawer-type structure. It can be understood that the first clothing processing device can also be a drawer-type structure, and the second clothing processing device can be a drum-type structure. The composite washing machine can be a washing machine or a washing machine and dryer combo.

[0128] Preferably, the first garment processing device 10 uses a bottom drainage method for drainage, while the second garment processing device 20 uses an top drainage method for drainage.

[0129] Specifically, a drain valve 33 is provided between the drain outlet of the first garment processing device 10 and the first drain pipe 31, and a drain pump 35 is provided between the drain outlet of the second garment processing device 20 and the second drain pipe 32.

[0130] In the above solution, the first garment processing device of the present invention uses a bottom drainage method for drainage, and the second garment processing device uses an top drainage method for drainage. When the second garment processing device has a drawer-type structure, it can avoid occupying too much space inside the second garment processing device, and the drain pipe will not be bent when the drawer is pulled out, thus affecting the drainage efficiency.

[0131] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
