Without further limitation, the element defined by the statement "including one..." does not exclude the existence of another identical element in the commodity or system including the said element.

[0042] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0043] As Figure 1 shown, taking a washing machine that drains water in the above-mentioned up-drainage method as an example, when the washing machine 1 operates the drainage program in the existing market, the first drainage pump 2 in the washing machine 1 starts to work, and the water-scooping blades in the first drainage pump 2 rotate, and the washing water in the laundry treatment cylinder 3 is drained along the drainage pipe 4 into the floor drain 5.

[0044] Among them, the layout of the drainage pipe of the washing machine that drains water in the above-mentioned up-drainage method is as Figure 1 shown. A reverse U-shaped structure is formed in the drainage pipe 4 between the floor drain 5 and the first drainage pump 2, that is, a horizontal section is formed at the highest position in the drainage pipe 4 arrangement area of the part of the drainage pipe 4 between the floor drain 5 and the first drainage pump 2.

[0045] The problem of drainage air entrapment caused by the washing machine draining water in the up-drainage method is that when the drainage is about to end, the last part of the washing water flows back, resulting in the remaining water in the drainage pipe 4 not being drained. When the washing machine fills with water next time, because the water intake of the washing machine is relatively large, for example, the water intake can reach (6L - 8L) / min, the water outlet of the outer cylinder of the washing machine is quickly closed by water. At this time, there is a section of air segment in the drainage pipe 4. Because the drainage pipe near the floor drain side also has the washing water that was not drained last time, the state shown in Figure 1 is formed in the drainage pipe 4, that is, an intermediate air segment 6 is formed between the washing water filled this time and the water remaining last time.

[0046] When the intermediate air segment 6 is at the position of the water-scooping blade of the first drainage pump 2, the water-scooping blade cannot contact the water in the drainage pipe 4 when it rotates, thereby causing the problem of drainage air entrapment in the drainage pipe 4, resulting in the failure of the washing machine to drain water. Moreover, the above problem cannot be solved after the washing machine is restarted. The user can only lay the drainage pipe flat and wait for the stagnant water in the drainage pipe to flow out before the next drainage can be carried out, resulting in a poor user experience.

[0047] Based on the above technical problems, an exemplary embodiment of the present utility model provides a drainage member 100, and the drainage member is applicable to a laundry treatment device 300.

[0048] Among them, the laundry treatment device 300 may include, but is not limited to, a washing machine, and the washing machine may include, but is not limited to, an integrated washing and care machine, a washing and drying integrated machine, etc. For example, the washing machine may be a drum washing machine or a pulsator washing machine with drying or washing and care functions. Of course, the washing machine may also be other types of fully automatic washing machines. In this example and the following examples, the laundry treatment device 300 is taken as a drum washing machine that drains water in an upper drainage manner for illustration.

[0049] Such as Figure 2 And in combination with Figure 3 And Figure 4 As shown, the drain part 100 includes a drain body 110, and a water inlet end 111 and a water outlet end 112 are respectively arranged at both ends of the drain body 110.

[0050] Among them, the drain body 110 may be a pipe-like structure, and the cross-sectional shape of the pipe-like structure may include, but is not limited to, a circle, a regular polygon, etc. The material used to manufacture the drain body 110 may include, but is not limited to, ethylene-vinyl acetate copolymer (abbreviated as EVA), polyvinyl chloride (abbreviated as PVC), linear low-density polyethylene (abbreviated as LLDPE), or polyethylene (abbreviated as PE), etc.

[0051] The water inlet end 111 of the drain body 110 may be connected to the water outlet of the drain pump 200 in the drum washing machine, and the water inlet of the drain pump 200 may be communicated with the drain port in the drum washing machine. Based on this, the washing water in the drum of the drum washing machine can be discharged through the drain pump 200.

[0052] The water outlet end 112 of the drain body 110 may be arranged outside the drum washing machine and directly inserted into the floor drain in a plug-in manner, or connected to the floor drain through a check valve or other structures to convey the washing water in the drum to the floor drain.

[0053] Continue to refer to Figure 1 As shown, a part of the drain body 110 near the water inlet end 111 arches upward to form an arched section 113, and both sides of the vertex of the arched section 113 bend downward.

[0054] Among them, the arched section 113 may be arched upward in the vertically upward direction. The plane perpendicular to the bottom surface of the drum washing machine and passing through the lowest points of the water inlet end 111 and the water outlet end 112 is the vertical plane. And among the vertex (i.e., the highest point) of the arched section 113 and the lowest points of the water inlet end 111 and the water outlet end 112 respectively, the plane where the triangle formed by the connection of the three points is located coincides with the vertical plane.

[0055] Alternatively, it can also be formed by the arched section 113 arching upward in an obliquely upward direction. That is to say, when the lowest points of the water inlet end 111 and the water outlet end 112, namely the two points, are in a vertical plane, while the vertex of the arched section 113 is not in the vertical plane. That is, among the vertex (i.e., the highest point) of the arched section 113 and the lowest points of the water inlet end 111 and the water outlet end 112 respectively, the plane where the triangle formed by connecting the three points is inclined at a predetermined angle with respect to the vertical plane. The inclination range of the predetermined angle can be between 0° and 75°, excluding 0° and including 75°.

[0056] It should be noted that in this example, the positions of the lowest points of the water inlet end 111 and the water outlet end 112 are not limited. Therefore, the above-mentioned vertical plane can vary according to the different positions of the lowest points of the water inlet end 111 and the water outlet end 112. That is, there can be countless vertical planes as the positions of the lowest points of the water inlet end 111 and the water outlet end 112 are different, such that among the vertex (i.e., the highest point) of the arched section 113 and the lowest points of the water inlet end 111 and the water outlet end 112 respectively, there are also countless planes where the triangle formed by connecting the three points is located. That is to say, the position or angle at which the arched section 113 arches upward or in an obliquely upward direction can be flexibly set according to the different structural spaces inside the drum washing machine.

[0057] Regardless of how the arching direction or the arching deflection angle of the arched section 113 is set, it is necessary to bend both sides of the vertex of the arched section 113 downward to prevent the washing water from remaining at the vertex position of the arched section 113 when the drainage member 100 is performing the drainage operation.

[0058] Refer to Figure 2 As shown, when using the drainage member 100 to perform the drainage operation, through the structural design of the arched section 113, the washing water that was not completely drained last time can be made to flow back to a position close to the water outlet end 112, thereby forming a water storage section 114.

[0059] To avoid the formation of an intermediate air section 6 as in Figure 1 , the horizontal position of the lowest point of the water inlet end 111 is designed to be lower than or equal to the horizontal position of the highest point of the water storage section 114, and the water inlet end 111 is connected to the water inlet of the drainage pump 200. That is to say, the position of the water storage section 114 will be higher than or equal to the position of the water deflecting blade of the drainage pump 200.

[0060] Based on this, when the drainage member 100 is used to perform a drainage operation, due to the washing water left in the water storage section 114 from the previous drainage operation, according to the principle of communicating vessels, the water deflecting blades of the drainage pump 200 will surely be submerged by the washing water that enters through the drainage port of the drum washing machine this time. Thus, it can be ensured that the water deflecting blades of the drainage pump 200 can deflect the washing water when rotating. In this way, the situation of drainage air entrapment can be effectively avoided, and further, it can be effectively ensured that the washing water in the drum is smoothly drained outside the drum washing machine, realizing rapid drainage and improving the drainage efficiency.

[0061] As Figure 2 shown, the drainage body 110 includes a first section 11a and a second section 11b connected in sequence. The water inlet end 111 is provided at one end of the first section 11a, the other end of the first section 11a is connected to one end of the second section 11b, and the arched section 113 is located at the connection position between the first section 11a and the second section 11b. The water outlet end 112 is located at the other end of the second section 11b.

[0062] Among them, the water storage section 114 is located in the second section 11b and close to the position of the water outlet end 112.

[0063] It should be noted that the first section 11a is inclined upward, or the first section 11a is inclined obliquely upward. From the top to the bottom of the second section 11b, it is inclined downward, or the second section 11b is inclined obliquely downward from the position of the arched section 113.

[0064] The first section 11a can be symmetrically arranged with the second section 11b, or the inclination directions of the first section 11a and the second section 11b are different.

[0065] In this example, the inclination angles of the first section 11a and the second section 11b can be flexibly set according to the internal structural space of the drum washing machine, so as to avoid the situation of drainage air entrapment in the drainage body 110, provide a good structural basis for the smooth drainage of the subsequent drainage member 100, and further ensure the drainage efficiency.

[0066] As Figure 5 shown, in some embodiments, the drainage body 110 further includes a third section 11c. One end of the third section 11c is connected to the water outlet end 112, and the other end of the third section 11c is located outside the laundry treatment device, i.e., the drum washing machine.

[0067] It should be noted that the water outlet end 112 can be located outside or inside the drum washing machine. When the water outlet end 112 is located outside the drum washing machine, the water outlet end 112 can be directly plugged into the floor drain for drainage. Or, when the placement position of the drum washing machine is far from the floor drain, a third section 11c can be externally connected to the water outlet end 112 to extend the length of the drainage body 110, so as to ensure that the washing water in the drum of the drum washing machine can be smoothly discharged from the floor drain.

[0068] To ensure the smoothness of the drainage process of the drainage body 110, the connection position between the second section 11b and the third section 11c is designed as a smooth transition section.

[0069] As Figure 2 shown, in some embodiments, the connection line between the lowest point of the water outlet end 112 and the highest point of the arched section 113 forms a first straight line L1. The connection line between the lowest point of the water inlet end 111 and the highest point of the arched section 113 forms a second straight line L2, and the angle α formed between the first straight line L1 and the second straight line L2 ranges from 15° to 60°.

[0070] Among them, when the angle α formed between the first straight line L1 and the second straight line L2 is less than 15°, the distance between the first section 11a and the second section 11b is too close, and the bending degree of the top of the formed arched section 113 is too small, resulting in unsmooth drainage and also being inconvenient for the installation of the first section 11a and the second section 11b. When the angle α formed between the first straight line L1 and the second straight line L2 is greater than 60°, it will cause the angle formed between the first section 11a and the second section 11b to be too large and occupy a large space volume. Therefore, the angle α formed between the first straight line L1 and the second straight line L2 ranges from 15° to 60°.

[0071] In one example, the angle α formed between the first straight line L1 and the second straight line L2 is preferably in the range of 20° to 50°.

[0072] In a specific example, the angle α formed between the first straight line L1 and the second straight line L2 is 45°.

[0073] It should be noted that the angle α between the first straight line L1 and the second straight line L2 can be flexibly set according to the internal structural space of the drum washing machine. Or, it can also be flexibly set according to the capacity of the drum washing machine. For example, when the capacity of the drum washing machine is larger, the angle α between the first straight line L1 and the second straight line L2 is also larger, and the lengths of the first section 11a and the second section 11b can also be lengthened as the volume of the drum washing machine increases.

[0074] In this example, by limiting the angle α between the first straight line L1 and the second straight line L2, it can be ensured that the washing water can stay in the water storage section 114 during the last drainage of the washing machine. At the same time, the internal structural space of the drum washing machine can be reasonably utilized, and the space volume occupied by the drainage member 100 during its layout can be saved.

[0075] As Figure 2 shown, in some embodiments, the vertical distance H between the highest point of the arched section 113 and the lowest point of the water inlet end 111 ranges from 4 cm to 40 cm.

[0076] Among them, when the vertical distance H between the highest point of the arched section 113 and the lowest point of the water inlet end 111 is less than 4 cm, the formed arched section 113 will be too low, and at the same time, the arched angle formed by the arched section 113 will be relatively sharp, resulting in poor drainage effect.

[0077] When the vertical distance H between the highest point of the arched section 113 and the lowest point of the water inlet end 111 is higher than 40 cm, although the first section 11a and the second section 11b can be flexibly set, it will increase the dimensional cost of the first section 11a and the second section 11b. At the same time, it will also occupy a relatively large space volume inside the drum washing machine, thereby causing the external dimensions of the drum washing machine to become larger, making the design dimensions of the drum washing machine not very in line with the expected requirements of users.

[0078] Based on this, the vertical distance H between the highest point of the arched section 113 and the lowest point of the water inlet end 111 ranges from 4 cm to 40 cm. On the one hand, it can ensure the reasonable setting of the angle when the first section 11a and the second section 11b are arranged. On the other hand, it can also ensure the structural requirements of the arched section 113 formed when the first section 11a and the second section 11b are arranged, thereby ensuring the smoothness of the subsequent drainage process of the drainage body 110 and improving the drainage efficiency.

[0079] In an example, the preferred range of the vertical distance H between the highest point of the arched section 113 and the lowest point of the water inlet end 111 is from 5 cm to 30 cm.

[0080] Alternatively, the range of the vertical distance H from the highest point of the arched section 113 to the horizontal plane is from 5 cm to 30 cm.

[0081] It should be noted that the height value of the position where the highest point of the arched section 113 is located can vary according to the capacity of the drum washing machine. For example, when the capacity of the drum washing machine is between 1 Kg and 3 Kg, the range of the vertical distance H from the position where the highest point of the arched section 113 is located to the horizontal plane can be between 5 cm and 15 cm, or the range of the vertical distance H between the highest point of the arched section 113 and the lowest point of the water inlet end 111 can be between 5 cm and 15 cm.

[0082] When the capacity of the drum washing machine is between 3 Kg and 10 Kg, the range of the vertical distance H from the position where the highest point of the arched section 113 is located to the horizontal plane can be between 15 cm and 30 cm, or the range of the vertical distance H between the highest point of the arched section 113 and the lowest point of the water inlet end 111 can be between 15 cm and 30 cm.

[0083] In some embodiments, taking the plane perpendicular to the line connecting the lowest points of the water inlet end 111 and the water outlet end 112 as the longitudinal section, the plane formed by the three points of the highest point of the arched section 113, the lowest point of the water inlet end 111, and the lowest point of the water outlet end 112 is an inclined plane.

[0084] For the relative flexibility of the layout position of the drainage body 110, the range of the angle between the inclined plane and the longitudinal section is set between 0° and 60°.

[0085] When the angle between the inclined plane and the longitudinal section is 0°, at this time, the inclined plane coincides with the longitudinal section, that is to say, the inclined plane is set perpendicular to the horizontal plane. The highest point of the arched section 113 can be set to bias towards the lowest point of the water inlet end 111, or the highest point of the arched section 113 can also be set to bias towards the lowest point of the water outlet end 112, or the lowest points of the water inlet end 111 and the water outlet end 112 are symmetrically arranged on both sides of the highest point of the arched section 113.

[0086] In a preferred example, the highest point of the arched section 113 can be set to bias towards the lowest point of the water inlet end 111, so that when draining water for the last time during the drainage operation, the washing water can stay in the water storage section 114, ensuring the smoothness of drainage, thereby improving the drainage efficiency of the drainage part 100.

[0087] As Figures 2 to 5 shown, in some embodiments, the drainage part 100 is a drainage pipe, and the drainage pipe is configured to drain the washing medium in the drum of the laundry treatment device, that is, the drum washing machine. The washing medium may include but is not limited to washing water.

[0088] The drain pipe can be made of PVC drain pipe, where PVC is PolyVinyl Chloride. Alternatively, the drain pipe can also be made of aluminum-plastic composite pipe, stainless steel drain pipe or plastic drain pipe, etc.

[0089] As Figure 3 shown, an exemplary embodiment of the present utility model also provides a drainage device, which is applicable to the laundry treatment device 300, that is, applicable to a drum washing machine.

[0090] The laundry treatment device 300 includes a laundry treatment drum, and a drain port (not shown in the figure) is provided on the laundry treatment drum.

[0091] The drainage device includes a drainage pump 200 and the drainage member 100 of any of the above embodiments. Among them, the water inlet of the drainage pump 200 is connected to the drain port, the water inlet end 111 of the drainage member 100 is communicated with the water outlet of the drainage pump 200, and the water outlet end 112 of the drainage member 100 is located outside the laundry treatment drum, or the water outlet end 112 of the drainage member 100 is located outside the laundry treatment device 300.

[0092] Among them, the drainage member 100 includes a drainage body 110, and the water inlet end 111 and the water outlet end 112 are respectively arranged at both ends of the drainage body 110.

[0093] The part of the drainage body 110 close to the water inlet end 111 arches upward to form an arched section 113, and both sides of the vertex of the arched section 113 are bent downward. And the arched section 113 can be arched upward along the vertically upward direction, or the arched section 113 can also be arched upward along the obliquely upward direction. When using the drainage member 100 for drainage operation, through the structural design of the arched section 113, the washing water that was not drained last time can be made to flow back to the position close to the water outlet end 112, so as to form a water storage section 114 at the position close to the water outlet end 112.

[0094] In order to avoid forming the intermediate air section 6 as Figure 1 again, the horizontal position of the lowest point of the water inlet end 111 is designed to be lower than or equal to the horizontal position of the highest point of the water storage section 114, and the water inlet end 111 is communicated with the water inlet of the drainage pump 200, that is to say, the position of the water storage section 114 and the position of the water deflecting blade of the drainage pump 200 will be at the same horizontal height.

[0095] Based on this, when the drainage member 100 is used to perform a drainage operation, due to the washing water from the previous drainage operation retained in the water storage section 114, according to the principle of communicating vessels, the water scooping blades of the drainage pump 200 will surely be submerged by the washing water that enters through the drainage port of the drum washing machine this time. Thus, it can be ensured that the water scooping blades of the drainage pump 200 can scoop up the washing water when rotating. In this way, the situation of drainage air entrapment can be effectively avoided, and further, it can be effectively ensured that the washing water in the drum is smoothly drained out of the drum washing machine, achieving rapid drainage and improving the drainage efficiency.

[0096] Among them, the drainage body 110 includes a first section 11a and a second section 11b connected in sequence. The water inlet end 111 is arranged at one end of the first section 11a, the other end of the first section 11a is connected to one end of the second section 11b, and the arched section 113 is located at the connection position between the first section 11a and the second section 11b. The water outlet end 112 is located at the other end of the second section 11b.

[0097] Among them, the water storage section 114 is located inside the second section 11b and close to the position of the water outlet end 112.

[0098] The connection line between the lowest point of the water outlet end 112 and the highest point of the arched section 113 forms a first straight line L1. The connection line between the lowest point of the water inlet end 111 and the highest point of the arched section 113 forms a second straight line L2. Then, the angular range of the included angle α formed between the first straight line L1 and the second straight line L2 is between 20° and 50°.

[0099] That is to say, by limiting the angle α between the first straight line L1 and the second straight line L2, it can be ensured that the washing water can be retained in the water storage section 114 during the last drainage of the washing machine, and the internal structural space of the drum washing machine can be reasonably utilized, saving the space volume occupied when arranging the drainage member 100.

[0100] On the other hand, the vertical distance H from the highest point of the arched section 113 to the horizontal plane ranges from 5 cm to 30 cm. On the one hand, it can ensure the reasonable setting of the angles when arranging the first section 11a and the second section 11b. On the other hand, it can also ensure the structural requirements of the arched section 113 formed when arranging the first section 11a and the second section 11b, thereby ensuring the smoothness of the subsequent drainage process of the drainage body 110 and improving the drainage efficiency.

[0101] Among them, the height value of the position where the highest point of the arched section 113 is located can be different according to the capacity of the drum washing machine. For example, when the capacity of the drum washing machine is 1 Kg to 3 Kg, the value range of the vertical distance H from the position where the highest point of the arched section 113 is located to the horizontal plane can be between 5 cm and 15 cm, or the value range of the vertical distance H between the highest point of the arched section 113 and the lowest point of the water inlet end 111 can be between 5 cm and 15 cm.

[0102] When the capacity of the drum washing machine is 3 Kg to 10 Kg, the value range of the vertical distance H from the position where the highest point of the arched section 113 is located to the horizontal plane can be between 15 cm and 30 cm, or the value range of the vertical distance H between the highest point of the arched section 113 and the lowest point of the water inlet end 111 can be between 15 cm and 30 cm.

[0103] In some embodiments, the drainage device further includes a fastener (not shown in the figure), and the fastener is used to fix the position of the highest point of the arched section 113 on the laundry treatment device 300. Among them, the fastener can include but is not limited to nylon cable ties, U-shaped fixing rings, etc.

[0104] The fastener can firmly fix the position of the highest point of the arched section 113 on the laundry treatment device 300 to ensure the stability of the drainage member 100 during the operation of the laundry treatment device 300 and ensure and improve the drainage efficiency of the drainage member 100.

[0105] As Figures 3 to 5 shown, an exemplary embodiment of the present invention further provides a laundry treatment device 300, and the laundry treatment device 300 includes a laundry treatment cylinder and the drainage device of any of the above embodiments. A drainage port (not shown in the figure) is provided on the laundry treatment cylinder.

[0106] The drainage device includes a drainage pump 200 and a drainage member 100. Among them, the water inlet of the drainage pump 200 is connected to the drainage port, the water inlet end 111 of the drainage member 100 is communicated with the water outlet of the drainage pump 200, and the water outlet end 112 of the drainage member 100 is located outside the laundry treatment cylinder, or the water outlet end 112 of the drainage member 100 is located outside the laundry treatment device 300.

[0107] Among them, the drainage member 100 includes a drainage body 110, and the water inlet end 111 and the water outlet end 112 are respectively arranged at both ends of the drainage body 110.

[0108] A part of the drainage body 110 near the water inlet end 111 arches upward to form an arched section 113, and both sides of the vertex of the arched section 113 bend downward. The arched section 113 can be arched upward along the vertically upward direction, or the arched section 113 can also be arched upward along the obliquely upward direction. When draining water using the drainage member 100, through the structural design of the arched section 113, the washing water that was not drained completely last time can be made to flow back to a position near the water outlet end 112, thereby forming a water storage section 114 at a position near the water outlet end 112.

[0109] In order to avoid forming an intermediate air section 6 as in Figure 1 , the horizontal position of the lowest point of the water inlet end 111 is designed to be lower than or equal to the horizontal position of the highest point of the water storage section 114, and the water inlet end 111 is communicated with the water inlet of the drainage pump 200. That is to say, the position where the water storage section 114 is located and the position of the water deflecting blade of the drainage pump 200 will be at the same horizontal height.

[0110] Based on this, when performing a drainage operation using the drainage member 100, due to the washing water of the previous drainage operation retained in the water storage section 114, according to the principle of communicating vessels, the water deflecting blade of the drainage pump 200 will surely be submerged by the washing water that enters through the drainage port of the drum washing machine this time, so that it can be ensured that the water deflecting blade of the drainage pump 200 can deflect the washing water when rotating. In this way, the situation of drainage air entrapment can be effectively avoided, and further, it can be effectively ensured that the washing water in the drum is smoothly drained to the outside of the drum washing machine, realizing rapid drainage and improving the drainage efficiency.
