[0038] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals designate like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0039] In the related art, the cleaning device for a laundry treatment device generally uses a double-pump structure. One pump drives drainage, and the other pump drives circulating self-cleaning. This not only increases the equipment cost but also makes it inconvenient to install the pump body. Therefore, how to optimize the pump body structure to achieve the drainage and self-cleaning functions while ensuring the drainage efficiency and facilitating installation has become an urgent problem to be solved in this field.

[0040] The following refers to Figures 1-9 Describe the drive pump for a cleaning device according to an embodiment of the present utility model.

[0041] The drive pump 1 for a cleaning device according to the present utility model includes: a pump body 11, a drainage cavity is formed in the pump body 11, and a first outlet 111 and a second outlet 112 communicated with the drainage cavity; an impeller 14, the impeller 14 is rotatably arranged in the drainage cavity and can be selectively rotated forward or backward to drive the condensed water in the drainage cavity to selectively flow to the first outlet 111 or the second outlet 112; a flow blocking portion 153, the flow blocking portion 153 is arranged in the drainage cavity and located between the first outlet 111 and the second outlet 112, and the flow blocking portion 153 protrudes from the inner wall of the drainage cavity.

[0042] Specifically, a drainage cavity is provided inside the pump body 11. The pump body 11 is provided with a water inlet 113, and the water inlet 113 can be arranged at the bottom of the drainage cavity, facilitating the condensate to enter the drainage cavity through the water inlet 113. A first outlet 111 and a second outlet 112 are arranged on the pump body 11 for communicating the drainage cavity with the outside. By providing the first outlet 111 and the second outlet 112, the pump body 11 can selectively discharge the condensate from the first outlet 111 or the second outlet 112 to meet different cleaning requirements. The impeller 14 is arranged inside the drainage cavity, and the centrifugal force generated by the rotation of the impeller 14 drives the flow of the condensate. When the impeller 14 rotates, its blades will interact with the water flow, thereby generating a thrust force to make the condensate flow inside the drainage cavity and finally be discharged through the first outlet 111 or the second outlet 112. Among them, the impeller 14 can guide the condensate to be discharged from the first outlet 111 or the second outlet 112 by rotating forward or backward. When the amount of condensate is insufficient, the liquid level of the condensate in the confluence cavity is relatively low. When the pump body 11 discharges water through the first outlet 111, due to the influence of the internal and external pressure difference on the pump body 11, external gas will enter the drainage cavity through the second outlet 112, resulting in pressure relief inside the drainage cavity and reducing the drainage capacity of the pump body 11. A flow blocking portion 153 is arranged between the first outlet 111 and the second outlet 112, and the flow blocking portion 153 protrudes from the inner wall of the drainage cavity. Since the flow blocking portion 153 reduces the intake aperture inside the drainage cavity and blocks the external gas, it is beneficial to weaken the influence of the external gas on the internal pressure of the pump body 11, thereby ensuring the drainage capacity of the pump body 11.

[0043] Among them, the flow blocking portion 153 can be integrally formed with the pump body 11 or can be configured to be detachably arranged inside the pump body 11.

[0044] According to the driving pump 1 for the cleaning device of the present utility model, a first outlet 111 and a second outlet 112 are arranged on the pump body 11. By rotating the impeller 14, the condensate can be selectively driven to be discharged from the first outlet 111 or the second outlet 112, realizing the two-way drainage of the pump body 11 to meet different cleaning requirements. The structure of the pump body 11 is simple and convenient for arrangement. A flow blocking portion 153 is arranged inside the drainage cavity, and the flow blocking portion 153 protrudes from the inner wall of the drainage cavity. Since the flow blocking portion 153 reduces the intake aperture inside the drainage cavity and blocks the external gas, it is beneficial to weaken the influence of the external gas on the internal pressure of the pump body 11, thereby ensuring the drainage capacity of the pump body 11.

[0045] According to some embodiments of the present utility model, the drainage cavity includes: a confluence cavity, a first flow channel 114 and a second flow channel 115 communicating with the confluence cavity. An inlet 113 communicating with the outside is provided at the bottom of the confluence cavity. A first outlet 111 and a second outlet 112 are respectively provided on the first flow channel 114 and the second flow channel 115. Among them, a flow blocking portion 153 is provided in the confluence cavity and located between the inlets of the first flow channel 114 and the second flow channel 115.

[0046] Specifically, by forming the inlet 113 at the bottom of the confluence cavity, it is convenient to submerge the inlet 113 below the condensate liquid level, facilitating the introduction of condensate into the confluence cavity and improving the drainage efficiency. The first flow channel 114 and the second flow channel 115 are respectively communicated with the confluence cavity. By the rotation of the impeller 14, the condensate in the confluence cavity is guided into the first flow channel 114 or the second flow channel 115, the condensate is centrally discharged, and the flow direction of the condensate is controlled, which is beneficial to improving the drainage efficiency and keeping the drainage more stable. The first flow channel 114 is communicated with the first outlet 111, and the second flow channel 115 is communicated with the second outlet 112. The first flow channel 114 and the second flow channel 115 are respectively communicated with the confluence cavity, so that after the condensate flows through the first flow channel 114 or the second flow channel 115, it can be smoothly discharged through the first outlet 111 or the second outlet 112, which not only simplifies the water flow path but also improves the discharge efficiency. The flow blocking portion 153 is provided in the confluence cavity and located between the inlets of the first flow channel 114 and the second flow channel 115. When the impeller 14 rotates forward to introduce the condensate into the first flow channel 114 and drain it through the first outlet 111, the flow blocking portion 153 can block the outside air from flowing into the confluence cavity through the second outlet 112, reducing the influence of the outside gas on the internal pressure of the pump body 11 and ensuring stable drainage. Similarly, when the pump body 11 drains water through the second outlet 112, the flow blocking portion 153 can block the outside gas from entering the pump body 11 through the first outlet 111, ensuring the drainage capacity of the pump body 11.

[0047] According to some embodiments of the present utility model, the first flow channel 114 and the second flow channel 115 extend tangentially along the confluence cavity.

[0048] Specifically, the first flow channel 114 and the second flow channel 115 extend tangentially along the confluence cavity, which helps to enhance the fluidity of the condensed water in the flow channels. When the impeller 14 rotates, the centrifugal force generated will cause the condensed water to flow rapidly along the tangential direction of the impeller 14, making it easier to flow into the tangentially extending first flow channel 114 or the second flow channel 115, thereby improving the drainage efficiency. The tangentially extending flow channel design can reduce the turbulence generated by the condensed water in the first flow channel 114 or the second flow channel 115, making the flow of the condensed water smoother and more stable, and making the pump body 11 more stable and reliable during operation. The first flow channel 114 and the second flow channel 115 extend tangentially, which helps to evenly distribute the condensed water from the confluence cavity into the two flow channels, avoiding vibration and noise problems caused by uneven water flow.

[0049] According to some embodiments of the present invention, the first outlet 111 and the second outlet 112 are respectively open towards the height direction of the pump body 11.

[0050] Specifically, the first outlet 111 and the second outlet 112 are respectively open towards the height direction of the pump body 11, providing greater flexibility for the overall layout of the pump body 11. Among them, the first outlet 111 and the second outlet 112 can be arranged at the top of the pump body 11 and open towards the height direction. When the pump body 11 is arranged at the bottom of the cleaning device, it is more convenient for the pump body 11 to communicate with relevant components through the first outlet 111 and the second outlet 112. When the pump body 11 drains water through the first outlet 111 or the second outlet 112, it is beneficial to reduce the water flow resistance, enabling the condensed water to be discharged more quickly.

[0051] According to some embodiments of the present invention, the driving pump 1 further includes: a driving device 13, which is arranged on the top of the confluence cavity and connected to the impeller 14; the impeller 14 includes: a base 141, which is arranged on the top of the confluence cavity and connected to the driving device 13; the first blade 142, which is configured as an arc-shaped blade extending radially, and the first blade 142 is circumferentially spaced on the base 141.

[0052] Specifically, the driving device 13 is connected to the impeller 14 and provides power for the impeller 14. Through the operation of the driving device 13, the impeller 14 can start to rotate and generate centrifugal force, thereby pushing the condensed water in the confluence cavity towards the first flow channel 114 or the second flow channel 115 and discharging it through the first outlet 111 or the second outlet 112. The driving device 13 can selectively drive the impeller 14 to rotate forward or backward, so that the pump body 11 can flexibly adjust the discharge path of the condensed water during operation to meet different cleaning requirements. The driving device 13 is arranged at the top of the confluence cavity and is connected to the impeller 14, which not only ensures the efficiency and stability of power transmission, but also enables the driving device 13 to conveniently control the rotation direction of the impeller 14, making the connection between the impeller 14 and the driving device 13 more compact. When the driving device 13 drives the impeller 14 to rotate forward, the centrifugal force generated by the impeller 14 will push the condensed water from the confluence cavity towards the first flow channel 114, and the condensed water will finally be discharged from the pump body 11 through the first outlet 111. When the driving device 13 drives the impeller 14 to rotate backward, at this time the direction of the centrifugal force generated by the impeller 14 changes, pushing the condensed water towards the second flow channel 115, and the condensed water will finally be discharged from the pump body 11 through the second outlet 112. By driving the impeller 14 to rotate forward or backward by the driving device 13, the flow direction of the condensed water can be flexibly adjusted to meet different cleaning requirements.

[0053] The base 141 is arranged at the top of the confluence cavity and is connected to the driving device 13. The base 141 not only bears the weight of the entire impeller 14, but also drives the impeller 14 to rotate through the power transmitted by the driving device 13. The first blade 142 is configured as an arc-shaped blade extending radially. This shape design enables the blade to generate a large centrifugal force when rotating, thereby pushing the condensed water in the confluence cavity towards the drainage cavity. At the same time, the arc-shaped blade has a certain tangential contact with the convection when rotating, which is beneficial to reducing the impact of the blade on the water flow, thereby reducing noise. The first blades 142 are arranged at intervals along the circumference on the base 141, ensuring uniform force between the blades, reducing turbulence, enabling the water flow to pass through the blades more smoothly and flow along a predetermined direction, and improving the discharge efficiency of the condensed water.

[0054] According to some embodiments of the present invention, the impeller 14 further includes: a second blade 143, the second blade 143 is arranged on the first blade 142 and is located at the bottom of the first blade 142, and the radial dimension of the second blade 143 is smaller than the radial dimension of the first blade 142.

[0055] Specifically, the second blade 143 is disposed at the bottom of the first blade 142, so that the second blade 143 can further guide the water flow on the basis of the first blade 142, enhancing the drainage effect of the impeller 14. The radial dimension of the second blade 143 is smaller than that of the first blade 142. When the water flow passes through the first blade 142, most of the condensate is pushed towards the first flow channel 114 or the second flow channel 115, and the remaining condensate will continue to flow towards the first flow channel 114 or the second flow channel 115 under the guidance of the second blade 143, improving the drainage efficiency of the impeller 14. When the liquid level of the condensate in the drainage cavity is relatively low, the second blade 143 can extend below the liquid level. Even if the first blade 142 cannot reach below the liquid level, the second blade 143 can drive the condensate to flow, thus ensuring the drainage capacity of the pump body 11.

[0056] According to some embodiments of the present invention, the driving pump 1 further includes: a flow blocking portion 151, which is disposed on the bottom surface of the confluence cavity and on the side of the water inlet 113 facing the first flow channel 114 and the second flow channel 115, and the flow blocking portion 151 protrudes from the bottom surface of the confluence cavity.

[0057] Specifically, the flow blocking portion 151 is disposed at the bottom of the confluence cavity and on the side of the water inlet 113 facing the first flow channel 114 and the second flow channel 115. The flow blocking portion 151 is disposed between the first flow channel 114 and the second flow channel 115 and protrudes from the bottom surface of the confluence cavity. When the impeller 14 rotates forward, the flow blocking portion 151 will block the condensate from flowing into the second flow channel 115, ensuring that the condensate can only be discharged along the first flow channel 114; when the impeller 14 rotates in reverse, the flow blocking portion 151 will block the condensate from flowing towards the first flow channel 114, so that the condensate can only be discharged along the second flow channel 115. By precisely controlling the flow of the condensate between the flow channels, the flow blocking portion 151 ensures that the pump body 11 can maintain a high efficiency during the drainage process. Whether the impeller 14 rotates forward or in reverse, the condensate can be accurately guided to the corresponding flow channel and discharged from the pump body 11. By setting the flow blocking portion 151, the mutual interference between the first flow channel 114 and the second flow channel 115 is avoided, and the drainage efficiency of the pump body 11 is improved.

[0058] According to some embodiments of the present invention, first diversion inclined surfaces 1511 that extend obliquely from the water inlet 113 towards the first flow channel 114 and second diversion inclined surfaces 1512 that extend obliquely from the water inlet 113 towards the second flow channel 115 are respectively formed on both sides of the flow blocking portion 151.

[0059] Specifically, the first diversion inclined surface 1511 is formed on one side of the flow blocking portion 151 and extends obliquely from the water inlet 113 towards the first flow channel 114, enabling the condensed water in the confluence cavity to smoothly flow into the first flow channel 114 under the guidance of the first diversion inclined surface 1511. The first diversion inclined surface 1511 not only reduces the resistance of the water flow during the flowing process but also improves the efficiency of the condensed water flowing into the first flow channel 114. When the impeller 14 rotates forward, the flow blocking portion 151 blocks the condensed water from flowing into the second flow channel 115, while the first diversion inclined surface 1511 ensures that the condensed water can quickly and stably enter the first flow channel 114, thereby improving the drainage performance of the pump body 11. The second diversion inclined surface 1512 is formed on the other side of the flow blocking portion 151, opposite to the first diversion inclined surface 1511, and extends obliquely from the water inlet 113 towards the second flow channel 115, enabling the condensed water in the confluence cavity to smoothly flow into the second flow channel 115 under the guidance of the second diversion inclined surface 1512 when the impeller 14 rotates in reverse. The second diversion inclined surface 1512 reduces the resistance of the water flow during the flowing process and improves the efficiency of the condensed water flowing into the second flow channel 115. When the impeller 14 rotates in reverse, the flow blocking portion 151 blocks the condensed water from flowing towards the first flow channel 114, while the second diversion inclined surface 1512 ensures that the condensed water can quickly and stably enter the second flow channel 115. The design of the first diversion inclined surface 1511 and the second diversion inclined surface 1512 makes the flow path of the condensed water in the confluence cavity more reasonable and efficient. By respectively arranging the first diversion inclined surface 1511 and the second diversion inclined surface 1512 on both sides of the flow blocking portion 151, the mutual influence between the first flow channel 114 and the second flow channel 115 is reduced, and the discharge efficiency of the condensed water is improved.

[0060] According to some embodiments of the present invention, the driving pump 1 further includes: a first pipeline 121 and a second pipeline 122. The first pipeline 121 communicates the first flow channel 114 with the outside and has a first outlet 111, and the second pipeline 122 communicates the second flow channel 115 with the outside and has a second outlet 112. The first pipeline 121 and the second pipeline 122 respectively extend along the height direction of the pump body 11.

[0061] Specifically, a first pipeline 121 and a second pipeline 122 are provided on the pump body 11. The first pipeline 121 and the second pipeline 122 are respectively adapted to communicate the drainage cavity with the outside. Among them, the first pipeline 121 communicates the first flow channel 114 with the outside and is provided with a first outlet 111, and the second pipeline 122 communicates the second flow channel 115 with the outside and is provided with a second outlet 112. By providing the first pipeline 121 and the second pipeline 122 on the pump body 11, it is convenient to control the flow direction of the condensed water, making the discharge of the condensed water more orderly and controllable, and avoiding the formation of turbulence of the water flow inside the pump body 11. The first outlet 111 is provided on the first pipeline 121, and the second outlet 112 is provided on the second pipeline 122. Since the first pipeline 121 and the second pipeline 122 respectively extend along the height direction of the pump body 11, when the impeller 14 rotates, the condensed water can be pushed more directly and effectively towards the first pipeline 121 or the second pipeline 122, improving the discharge efficiency. The design of the first pipeline 121 and the second pipeline 122 extending in parallel also simplifies the overall structure of the pump body 11, making the manufacturing and installation processes more simple and fast. By optimizing the pipeline structure and the outlet position, the driving pump 1 not only maintains high-efficiency discharge but also improves the stability and reliability of the equipment.

[0062] According to some embodiments of the present invention, the driving pump 1 further includes: a guiding member 152, which is disposed in the drainage cavity and is adapted to guide the condensed water towards the first outlet 111 and / or the second outlet 112. A guiding surface extending towards the first outlet 111 and / or the second outlet 112 is formed on the guiding member 152.

[0063] Specifically, the guiding member 152 can be disposed in the first flow channel 114 or in the second flow channel 115. The guiding member 152 can be respectively disposed in the first flow channel 114 and the second flow channel 115. By providing the guiding member 152 to guide the flow direction of the condensed water in the flow channel, the flow of the condensed water becomes smoother and more efficient. The guiding member 152 can reduce the occurrence of vortex and turbulence phenomena, thereby improving the discharge efficiency and reducing the noise. For the guiding member 152 located in the first flow channel 114, at least a part of it forms a guiding surface extending towards the first outlet 111, and at least a part of the guiding member 152 located in the second flow channel 115 forms a guiding surface extending towards the second outlet 112. When the condensed water flows through the guiding member 152, it can be guided by the guiding surface, and the condensed water flows smoothly along the guiding surface towards the corresponding outlet and is discharged. The presence of the guiding member 152 not only improves the discharge efficiency of the condensed water but also enhances the stability of the pump body 11 during operation. By setting the guiding member 152 to control the water flow direction, the guiding member 152 reduces the vibration and noise problems caused by water flow disorder, making the pump body 11 operate more smoothly.

[0064] According to some embodiments of the present utility model, the flow guide member 152 includes: a main body portion 1521 that extends away from the impeller 14 in the tangential direction of the impeller 14, and a first flow guide surface extending in the height direction is formed on the top surface of the main body portion 1521; and / or a flow guide portion 1522 that is disposed around the outer periphery of the main body portion 1521 and protrudes from the top surface of the main body portion 1521, and a second flow guide surface extending in the height direction is formed on the flow guide portion 1522.

[0065] Specifically, the main body portion 1521 extends away from the impeller 14 along the tangential direction of the impeller 14, so that the main body portion 1521 can receive the water flowing out tangentially from the confluence cavity and guide it to flow in a predetermined direction. A first flow guide surface extending in the height direction is formed on the top surface of the main body portion 1521. Among them, the thickness of the main body portion 1521 gradually increases in the direction away from the impeller 14, so as to form a flow guide inclined surface or an arc surface on the top surface of the main body portion 1521, which not only enhances the strength and stability of the flow guide member 152, but also enables the main body portion 1521 to better control the flow direction and speed of the water flow. The flow guide portion 1522 is disposed around the outer periphery of the main body portion 1521 and protrudes from the top surface of the main body portion 1521. A second flow guide surface extending in the height direction is formed on the flow guide portion 1522, and the second flow guide surface can further guide the condensed water drained through the first flow guide surface to the first outlet 111 or the second outlet 112, and further guide the flow direction of the condensed water. Among them, the main body portion 1521 can be provided independently or synchronously with the flow guide portion 1522. Through the synergistic effect of the main body portion 1521 and the flow guide portion 1522, the flow guide member 152 can effectively guide the flow direction of the condensed water in the pump body 11, making it smoother and more efficient, which not only improves the drainage efficiency of the condensed water, but also reduces the vibration and noise problems caused by the water flow disorder.
