Description

Technical Field

[0001] The present invention belongs to the technical field of washing machines, and in particular, relates to a drainage structure and a washing machine. Background Art

[0002] With the rapid development of technologies related to clothing treatment equipment, it can bring great convenience to users. Most families need to purchase a variety of clothing treatment equipment. At this time, the user's recognition of clothing treatment equipment directly determines the user's purchase goal of replacing clothing treatment equipment.

[0003] At present, due to the overall high setting of the drainage pipes in some users' homes, the washing machines used in these users' homes must be drained through upper drainage, which can easily cause sewage to flow back into other pipes. It can be seen that this drainage method has limitations on users' choice of washing machines. At the same time, it also makes the drainage method of the lower drum of the double-drum washing machine have poor applicability and cannot meet the diverse needs of users.

[0004] The Chinese patent application number 202110806277.3 discloses a low-resistance three-way water pipe, including a pipeline main body and a side connecting pipe, wherein the side connecting pipe includes a side connecting section and a flaring section, wherein the side connecting section is connected to the flaring section, and the diameter of the flaring section is greater than the diameter of the side connecting section; the flaring section is seamlessly welded to the pipeline main body, so that the pipeline main body is connected to the side connecting pipe. The three-way pipeline is connected by seamlessly welding the flaring section to the pipeline main body, which reduces negative pressure, eliminates bubbles at the corners, and improves the life of the pipeline. At the same time, it can reduce noise and solve the problem of very large negative pressure of water at the welding corners.

[0005] The above-mentioned three-way water pipe realizes the drainage function by setting up a pipe main body, but this kind of drainage pipe cannot be directly applied to the double-drum drainage form, and the problem of sewage backflow may easily occur.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a drainage structure and a washing machine. By arranging a baffle in the first pipeline, the first pipeline is divided into two independent drainage channels, so that the upper drainage process and the lower drainage process do not affect each other, thereby preventing sewage backflow and causing pollution.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0009] A drainage structure, comprising:

[0010] A first pipeline having a through cavity;

[0011] A second pipeline is arranged on one side of the first pipeline and communicated with the cavity;

[0012] The baffle is arranged in the cavity to separate the cavity into two drainage channels which are not connected to each other.

[0013] Further, the first pipeline includes a first drainage channel and a second drainage channel, and the second drainage channel is connected to the second pipeline;

[0014] The baffle is disposed between the first drainage channel and the second drainage channel.

[0015] Furthermore, the baffle is extended along the axial direction of the first pipeline.

[0016] Furthermore, the second drainage channel includes a water inlet end and a drainage end, the water inlet end is covered with an end cover, and the end cover seals the second drainage channel.

[0017] Furthermore, a blocking piece is provided on the drainage end, and the blocking piece is rotatably arranged on the inner wall of the second drainage channel.

[0018] Furthermore, the blocking piece includes a rotating shaft, and both ends of the rotating shaft are respectively arranged on the mounting holes on the inner wall of the second drainage channel.

[0019] Furthermore, the baffle can be rotated from the water inlet end to the water discharge end.

[0020] Furthermore, the blocking piece extends outward from the rotating shaft and is in close contact with the inner wall of the second drainage channel.

[0021] According to another object of the present invention, a washing machine is provided, comprising the drainage structure described above, wherein the drainage structure comprises a first pipeline and a second pipeline.

[0022] Further, the washing machine comprises an upper drum and a lower drum, the drain port of the upper drum is connected to the first pipeline, and the drain port of the lower drum is connected to the second pipeline;

[0023] The drainage end of the first pipeline is communicated with an external drainage pipe.

[0024] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0025] In the present invention, the water discharged from the upper drum flows to the first pipeline and is discharged through the cavity in the first pipeline. The water discharged from the lower drum flows to the second pipeline and is also discharged through the cavity in the first pipeline, thus realizing the process of upper drainage and lower drainage. The baffle plate arranged in the cavity can separate the cavity into two independent drainage channels, so that during the lower drainage process, the sewage in the first pipeline is directly discharged from the cavity without flowing into the second pipeline, thus avoiding pollution of the second pipeline and improving the user experience.

[0026] In the present invention, the drainage end is provided with a baffle, which is used to close the drainage end to prevent sewage discharged from the first pipeline from flowing back into the second drainage channel through the drainage end, thereby avoiding contamination of the second pipeline.

[0040] The existing double-drum drainage pipeline generally adopts the upper drainage form, but this drainage form limits the user's choice of washing machine. At the same time, in the existing double-drum drainage pipeline, the sewage in the upper drum is easy to flow back to the lower drum using the upper drainage, causing pollution to the lower drum.

[0041] Embodiment 1

[0042] To solve the above technical problems, Figures 1 to 4 As shown, this embodiment provides a drainage structure, including:

[0043] The first pipeline 1 has a through cavity;

[0044] A second pipeline 2, arranged on one side of the first pipeline 1 and connected to the cavity;

[0045] The baffle 3 is arranged in the cavity to divide the cavity into two drainage channels which are not connected to each other.

[0046] In this embodiment, the washing machine includes an upper drum 6 and a lower drum 7. The upper drum 6 adopts a drainage form of lower drainage, that is, the drainage process is realized by the gravity of the water flow. The lower drum 7 adopts a drainage form of upper drainage, that is, the sewage is pumped out by the drainage pump 8 to realize the upper drainage process.

[0047] In this embodiment, the drainage structure includes a first pipeline 1 and a second pipeline 2. The first pipeline 1 is connected to the upper drum 6, and the sewage discharged from the upper drum 6 is discharged through the first pipeline 1. The second pipeline 2 is connected to the lower drum 7, and the drainage pump 8 extracts sewage and discharges it through the second pipeline 2.

[0048] In this embodiment, a through cavity is provided in the first pipeline 1, and the sewage discharged from the upper drum 6 is discharged through the cavity in the first pipeline 1, thereby realizing the drainage process of downward drainage.

[0049] Furthermore, the second pipeline 2 is arranged on one side of the first pipeline 1, and the second pipeline 2 is connected to the cavity. By installing the second pipeline 2 on one side of the first pipeline 1, the layout of the drainage structure can be effectively optimized and the volume of the drainage structure can be reduced. The sewage discharged from the lower drum 7 is drawn into the second pipeline 2 and discharged through the cavity connected to the second pipeline 2, thereby realizing the drainage process of upper drainage.

[0050] In this embodiment, the drainage structure also includes a baffle 3, which is arranged in the cavity to separate the cavity into two independent drainage channels. The baffle 3 can be used to prevent water drained in the first pipeline 1 from flowing back to the second pipeline 2, thereby preventing pollution of the second pipeline 2.

[0051] In the above scheme, the water discharged from the upper drum 6 flows to the first pipeline 1 and is discharged through the cavity in the first pipeline 1. The water discharged from the lower drum 7 flows to the second pipeline 2 and is also discharged through the cavity in the first pipeline 1, realizing the process of upper drainage and lower drainage. The baffle 3 arranged in the cavity can separate the cavity into two independent drainage channels, so that during the lower drainage process, the sewage in the first pipeline 1 is directly discharged from the cavity instead of flowing into the second pipeline 2, thereby avoiding pollution of the second pipeline 2 and improving the user experience.

[0052] like Figure 1 As shown, in a further solution of this embodiment, the first pipeline 1 includes a first drainage channel 11 and a second drainage channel 12, and the second drainage channel 12 is connected to the second pipeline 2; the baffle 3 is arranged between the first drainage channel 11 and the second drainage channel 12.

[0053] Specifically, the baffle 3 is disposed in the cavity of the first pipeline 1, and the cavity is divided into a first drainage channel 11 and a second drainage channel 12. The first drainage channel 11 is connected to the drainage port of the upper drum 6, and the sewage discharged from the upper drum 6 is directly discharged through the first drainage channel 11, realizing the drainage process of the lower drainage.

[0054] The second drainage channel 12 is connected to the second pipeline 2. The sewage discharged from the lower drum 7 is pumped to the second pipeline 2 by the drainage pump 8 and then flows out through the second drainage channel 12, thus realizing the drainage process of upper drainage.

[0055] In this embodiment, the baffle 3 is arranged between the first drainage channel 11 and the second drainage channel 12, so that the two form an independent drainage channel, which can effectively prevent the sewage discharged from the first drainage channel 11 from flowing into the second drainage channel 12, prevent the pollution of the second drainage channel 12, and ensure the cleanliness of the lower drum 7 connected to the second pipeline 2.

[0056] In a further solution of this implementation, the baffle 3 is extended along the axial direction of the first pipeline 1 .

[0057] Specifically, the baffle 3 is disposed in the cavity and extends a certain length along the axial direction of the first pipeline 1 , thereby dividing the cavity in the first pipeline 1 into two independent first drainage channels 11 and second drainage channels 12 .

[0058] More specifically, the vertical extension length of the baffle 3 is consistent with the length of the first pipeline 1, so that the baffle 3 can completely isolate the cavity to avoid the backflow of sewage.

[0059] In this embodiment, the extension length and thickness of the baffle 3 can be adaptively adjusted according to specific usage requirements, which will not be elaborated here.

[0060] like Figures 2 to 3 As shown, in a further solution of this embodiment, the second drainage channel 12 includes a water inlet end 121 and a drainage end 122 , and the water inlet end 121 is covered with an end cover 4 , and the end cover 4 seals the second drainage channel 12 .

[0061] Specifically, the second drainage channel 12 is provided with an inlet end 121 and a drainage end 122, and the inlet end 121 and the drainage end 122 are respectively arranged on both sides of the second drainage channel 12, the inlet end 121 is arranged close to the drainage port of the upper drum 6, and the drainage end 122 is connected to an external drainage pipe.

[0062] More specifically, an end cover 4 is provided at the water inlet end 121, and the end cover 4 covers the water inlet end 121 to close the second drainage channel 12, so that when the first pipeline 1 is connected with the drainage port of the upper drum 6, the sewage discharged from the upper drum 6 can only be discharged through the first drainage channel 11 of the first pipeline 1, that is, the sewage discharged from the upper drum 6 can only pass through the first drainage channel 11 to realize the drainage process of downward drainage.

[0063] In this embodiment, the first pipeline 1 can be set as a cylindrical structure, and the cross section of the first pipeline 1 is circular. The baffle 3 divides the cavity in the first pipeline 1 into two independent drainage channels, so the cross sections of the first drainage channel 11 and the second drainage channel 12 are both semicircular.

[0064] like Figure 3 As shown, in this embodiment, the end cover 4 is sealed on the water inlet end 121 of the second drainage channel 12, so the cross-section of the end cover 4 can be semicircular, so that the end cover 4 can be tightly sealed with the water inlet end 121, thereby improving the sealing performance of the end cover 4.

[0065] In this embodiment, the cross section and shape of the end cover 4 can be adaptively adjusted according to specific usage requirements, which will not be elaborated here.

[0066] In a further solution of this embodiment, a blocking piece 5 is provided on the drainage end 122 , and the blocking piece 5 is rotatably disposed on the inner wall of the second drainage channel 12 .

[0067] Specifically, the second drainage channel 12 includes an inlet end 121 and a drainage end 122 . The drainage end 122 is provided with a baffle 5 , which is used to close the drainage end 122 to prevent sewage discharged from the first pipeline 1 from flowing back into the second drainage channel 12 through the drainage end 122 .

[0068] More specifically, the baffle 5 is arranged in the second drainage channel 12, and the baffle 5 can rotate in the second drainage channel 12, so that the sewage discharged from the lower drum 7 is pumped into the second pipeline 2 through the drainage pump 8, and the sewage flows into the second drainage channel 12 connected thereto, and the sewage washes away the baffle 5, so that the baffle 5 rotates to open the opening of the drainage end 122, thereby realizing the drainage process of upper drainage.

[0069] like Figure 4 As shown, in a further solution of this embodiment, the blocking piece 5 includes a rotating shaft 51 , and both ends of the rotating shaft 51 are respectively arranged on the mounting holes on the inner wall of the second drainage channel 12 .

[0070] Specifically, the baffle 5 is further provided with a rotating shaft 51, and the rotating shaft 51 is installed in the second drainage channel 12. Both ends of the rotating shaft 51 are movably arranged on the inner wall of the second drainage channel 12, and can be rotated in the second drainage channel 12, so as to realize the rotation of the baffle 5 to open or close the drainage end 122.

[0071] More specifically, the rotating shaft 51 is disposed close to the baffle plate 3 , so that there is good sealing between the rotating shaft 51 and the baffle plate 3 , thereby preventing the sewage discharged from the first pipeline 1 from flowing back into the second drainage channel 12 .

[0072] In a further solution of this embodiment, the blocking piece 5 can be rotated from the water inlet end 121 to the water outlet end 122 .

[0073] Specifically, the baffle 5 is movably arranged in the second drainage channel 12, and the baffle 5 can only rotate from the side of the second drainage channel 12 from the water inlet end 121 to the drainage end 122, that is, during the drainage process of the second drainage channel 12, the sewage flows into the second drainage channel 12, impacting the baffle 5 to rotate, so that the baffle 5 rotates toward the side away from the water inlet end 121, thereby opening the opening of the drainage end 122, so that the sewage is discharged therethrough, realizing the upper drainage process.

[0074] To be more specific, when the first drainage channel 11 of the first pipeline 1 is draining, the sewage flows back to the drainage end 122 of the second drainage channel 12. At this time, the sewage impacts the baffle 5 set at the drainage end 122, causing the baffle 5 to rotate toward the water inlet end 121, thereby closing the drainage end 122, thereby preventing the sewage from flowing back from the drainage end 122 into the second drainage channel 12, thereby avoiding pollution of the second drainage channel 12.

[0075] In a further solution of this embodiment, the blocking piece 5 extends outward from the rotating shaft 51 and is in close contact with the inner wall of the second drainage channel 12 .

[0076] Specifically, the baffle 5 includes a rotating shaft 51, which is arranged close to the baffle plate 3. The baffle 5 extends from the rotating shaft 51 toward the inner wall of the second drainage channel 12 to form a semicircular baffle 5, so that the baffle 5 is tightly fitted with the inner wall of the second drainage channel 12, further improving the sealing performance of the baffle 5.

[0077] like Figure 5As shown, in a further solution of this embodiment, an inclined groove is provided at the water outlet of the drainage end 122, and the groove extends obliquely from the drainage end 122 toward the water inlet end 121 to form an inclined groove. By providing the groove, when the sewage flows back to the baffle 5, the groove can prevent the baffle 5 from continuing to rotate, thereby playing the role of closing the drainage end 122, thereby achieving the effect of preventing sewage from flowing back.

[0078] Embodiment 2

[0079] This embodiment is a further description of the above embodiment 1.

[0080] like Figure 5 As shown, in this embodiment, a washing machine is provided, comprising the drainage structure described above.

[0081] Furthermore, the washing machine includes an upper drum 6 and a lower drum 7, the drain outlet of the upper drum 6 is connected to the first pipeline 1, and the drain outlet of the lower drum 7 is connected to the second pipeline 2; the drain end 122 of the first pipeline 1 is connected to an external drain pipe.

[0082] Specifically, the drainage port of the upper drum 6 is connected to the first pipeline 1, so that the sewage discharged from the upper drum 6 is discharged through the first pipeline 1, and the lower drainage process of the upper drum 6 is realized. The drainage port of the lower drum 7 is connected to the second pipeline 2, so that the sewage discharged from the lower drum 7 is pumped by the drainage pump 8 and flows to the second pipeline 2, and then discharged through the first pipeline 1 connected thereto, and the upper drainage process of the lower drum 7 is realized.
