DETAILED DESCRIPTION
[0025] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0026] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0028] See also Figure 1-Figure 5 The utility model discloses a drainage structure, including a drainage housing 10, a blocking member 20 and a driving mechanism 30. A diversion cavity, a first conduction port 11 and a second conduction port 12 are provided in the drainage housing 10. The first conduction port 11 and the second conduction port 12 can be used as a water outlet and a water inlet, or as a water inlet and a water outlet, respectively. In this embodiment, the first conduction port 11 is used as a water outlet, and the second conduction port 12 is used as a water inlet. Both the first conduction port 11 and the second conduction port 12 are connected to the diversion cavity.
[0029] In addition, the above-mentioned blocking member 20 is arranged in the diversion cavity, and the blocking member 20 has a blocking end and a linkage end. Driven by the driving mechanism 30, the linkage end can drive the blocking end to move closer to or away from the first conducting port 11, so that the blocking end blocks or opens the first conducting port 11.
[0030] Specifically, the driving mechanism 30 includes a motor 31 and a linkage part. The linkage part is connected to the rotating shaft of the motor 31, and the linkage part can rotate under the drive of the motor 31. When the linkage part rotates, it cooperates with the linkage end of the blocking part 20. In this way, the rotation of the linkage part drives the linkage end of the blocking part 20 to move in a straight line, and then drives the blocking end to move along the guide cavity towards or away from the first conducting port 11.
[0031] On the basis of the above structure, when using the drainage structure in the present application, taking the application of the drainage structure to the drain outlet of the washing machine as an example, the second conducting port 12 can be connected to the drain outlet of the washing machine through a pipe joint, and the first conducting port 11 can be connected to the external drainage pipe.
[0032] When the washing machine is washing normally, the blocking member 20 can be in a blocking state close to the first conducting port 11. When draining water, the motor 31 can be started, and the rotating shaft of the motor 31 can drive the linkage member to rotate around the first rotation direction. Since the linkage member and the linkage end of the blocking member 20 are in transmission cooperation, the linkage member can drive the linkage end of the linkage blocking member 20 to move away from the first conducting port 11 when rotating, and then drive the blocking end to move away from the first conducting port 11, open the first conducting port 11, so that the water flow introduced into the diversion cavity from the second conducting port 12 can be discharged through the first conducting port 11 to achieve drainage.
[0033] When drainage is not needed, the rotation of the shaft of the motor 31 drives the linkage member to rotate in a second rotation direction, which is opposite to the first rotation direction. In this way, the rotation of the linkage member can link the linkage end of the blocking member 20 to approach the first conductive port 11 in a straight line direction and block the first conductive port 11 to achieve blocking.
[0034] In addition, since the movement of the blocking member 20 away from the first conducting port 11 is controlled by the linear movement of the blocking member 20, the position of the blocking member 20 away from the first conducting port 11 can be controlled to achieve partial or full opening of the first conducting port 11, which facilitates the control of the drainage volume.
[0035] In this way, in this embodiment, by controlling the forward or reverse rotation of the rotating shaft of the motor 31, the movement of the blocking member 20 in the diversion cavity is realized, and the opening or blocking action of the first conducting port 11 is realized, and the movement stroke of the blocking member 20 can be controlled by controlling the rotation range of the rotating shaft of the motor 31, and the opening speed of the blocking member 20 can also be achieved by controlling the rotation speed of the motor 31 to prevent the discharge water flow from being too fast.
[0036] Furthermore, the linkage member includes a gear 32 mechanism, corresponding to which a plurality of tooth grooves 21 are provided at the linkage end. The gear 32 mechanism is in transmission meshing engagement with the plurality of tooth grooves 21, so that when the rotating shaft of the motor 31 rotates, the gear 32 mechanism is driven to rotate, and the rotation of the gear 32 mechanism can drive the plurality of tooth grooves 21 meshing therewith to move, so that the linkage end of the blocking member 20 makes a linear motion in the arrangement direction of the plurality of tooth grooves 21, thereby driving the blocking end to approach or move away from the first conducting port 11.
[0037] It should be noted that in this embodiment, the teeth of the gear 32 mechanism are engaged with multiple tooth grooves 21 to achieve control of the movement position of the blocking member 20. Every time the gear 32 rotates through a tooth groove 21, the blocking member 20 moves a stroke, so that the opening and closing degree of the blocking member 20 can be controlled with higher accuracy.
[0038] Of course, the linkage part can also be a nut structure, and an external thread structure matching the thread of the nut is provided at the linkage end of the blocking part 20, that is, the motor 31 drives the nut to rotate, and the external thread of the linkage end of the blocking part 20 makes a linear motion relative to the nut.
[0039] Furthermore, in this embodiment, the gear 32 mechanism includes a transmission gear 32 , and the transmission gear 32 is in transmission engagement with a plurality of tooth grooves 21 , that is, the linkage is implemented by a single transmission gear 32 , thereby simplifying the structure.
[0040] In other cases, the gear 32 mechanism can also be implemented by using two or more transmission gears 32, so that the transmission speed is more stable.
[0041] Furthermore, the blocking member 20 in this embodiment includes a blocking rod and a flexible blocking head 22. One end of the blocking rod is linked to the linkage member, and the other end of the blocking rod is provided with a flexible blocking head 22. In this way, the above-mentioned linkage end is formed at one end of the linkage rod, and the blocking end is formed at one end of the linkage rod. The flexible blocking head 22 is used to seal and block the first conducting port 11. In this way, when the rotating shaft of the motor 31 rotates, the linkage member can be driven to rotate by the rotating shaft of the motor 31, thereby linking the blocking rod to perform blocking or opening.
[0042] Since a flexible sealing head 22 is provided at the end of the sealing rod, the first conducting port 11 is sealed with the flexible sealing head 22 during sealing. The flexible sealing head 22 can be deformed when subjected to force and seal to the inner wall or outer periphery of the first conducting port 11, thereby achieving a good sealing effect and preventing water leakage.
[0043] Of course, the flexible plugging head 22 can be realized by using a rubber plug or a silicone plug in the prior art. In addition, the sealing can be realized by setting a multi-layer sealing ring structure on the outer wall of the end of the plugging rod, which can be selected and set according to actual needs.
[0044] Furthermore, the sealing member 20 also includes a threaded hose 23, which is sleeved on the outside of the sealing rod; the end of the sealing rod extends out of the end of the threaded hose 23 and is connected to the flexible sealing head 22; the flexible sealing head 22 is used to compress the threaded hose 23 when moving away from the first conducting port 11. Based on this structure, since the flexible sealing head 22 passes through the threaded hose 23, when the sealing rod pulls the flexible sealing head 22 away from the first conducting port 11, the sealing rod can move inside the threaded hose 23, so that the flexible sealing head 22 outside can compress the threaded hose 23. During the compression of the threaded hose 23, the air and seepage inside the diversion cavity can be discharged.
[0045] Embodiment 2,
[0046] A washing machine includes the drainage structure of any one of the embodiments of Example 1, wherein the second conduction port 12 is connected to the drainage port of the washing machine. When the washing machine is performing a normal machine washing action, the blocking member 20 can be in a blocked state close to the first conduction port 11. When the washing machine is performing a normal machine washing action, the blocking member 20 can be in a blocked state close to the first conduction port 11. When performing a drainage action, the motor 31 can be started, and the rotating shaft of the motor 31 can drive the linkage member to rotate around the first rotation direction. Since the linkage member and the linkage end of the blocking member 20 are in transmission cooperation, the linkage member can drive the linkage end of the linkage blocking member 20 to move away from the first conduction port 11 when rotating, and then drive the blocking end to achieve movement away from the first conduction port 11, open the first conduction port 11, and allow the water flow introduced into the diversion cavity by the second conduction port 12 to be discharged through the first conduction port 11 to achieve drainage.
[0047] When drainage is not needed, the rotation of the shaft of the motor 31 drives the linkage member to rotate in a second rotation direction, which is opposite to the first rotation direction. In this way, the rotation of the linkage member can link the linkage end of the blocking member 20 to approach the first conductive port 11 in a straight line direction and block the first conductive port 11 to achieve blocking.
[0048] In addition, since the movement of the blocking member 20 away from the first conducting port 11 is controlled by the linear movement of the blocking member 20, the position of the blocking member 20 away from the first conducting port 11 can be controlled to achieve partial or full opening of the first conducting port 11, which makes it convenient to control the drainage volume and prevent the drainage water flow from being too fast.
[0049] The drainage structure in this embodiment is the same as that in the above-mentioned embodiment 1, and its structure and effect on the washing machine will not be described in detail here. The other structures of the washing machine are prior art and will not be described in detail here.
[0050] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
