Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present utility model and should not be construed as a limitation of the present utility model.

[0039] In the related art, the cleaning device for clothing treatment equipment generally uses a double-pump structure. One pump drives drainage and the other pump self-cleans. This not only increases the equipment cost but also increases the installation space of the pump body. Therefore, how to optimize the pump body structure so that it can both achieve drainage and self-cleaning while ensuring the drainage efficiency has become an urgent problem in this field.

[0040] The following refers toFigures 1-9 Describe a 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 inside the pump body 11, an inlet 113 communicating with the drainage cavity and a first outlet 111 and a second outlet 112 communicating the drainage cavity with the outside are formed on the pump body 11; an impeller 14, the impeller 14 is arranged in the drainage cavity and is adapted to drive the condensed water in the drainage cavity to be discharged through the first outlet 111 or the second outlet 112; a flow guide member 152, the flow guide member 152 is arranged in the drainage cavity and is adapted to guide the condensed water to the first outlet 111 and / or the second outlet 112, and the flow guide member 152 is formed with a flow guide surface extending towards the first outlet 111 and / or the second outlet 112.

[0042] Specifically, a drainage cavity is arranged inside the pump body 11, an inlet 113 is provided on the pump body 11, and the inlet 113 can be arranged at the bottom of the drainage cavity to facilitate the condensed water to enter the drainage cavity through the inlet 113. A first outlet 111 and a second outlet 112 are arranged on the pump body 11 to communicate 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 condensed water through the first outlet 111 or the second outlet 112 to meet different cleaning requirements. The impeller 14 is arranged in the drainage cavity, and the centrifugal force generated by the rotation of the impeller 14 drives the flow of the condensed water. When the impeller 14 rotates, its blades will interact with the water flow, thereby generating a thrust force to make the condensed water flow in 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 condensed water to the first outlet 111 or the second outlet 112 to be discharged by rotating forward or backward. The flow guide member 152 is arranged in the drainage cavity, and its main function is to guide the flow direction of the condensed water to ensure that the condensed water can flow smoothly to the first outlet 111 or the second outlet 112. The flow guide member 152 is formed with a flow guide surface extending towards the first outlet 111 and / or the second outlet 112, and the flow guide surface can change the flow trajectory of the condensed water to make it closer to the first outlet 111 or the second outlet 112, thereby improving the drainage efficiency. The design of the flow guide member 152 makes the flow of the condensed water in the drainage cavity more orderly and efficient. The flow guide member 152 reduces the water flow resistance and increases the drainage speed.

[0043] According to the present utility model, the driving pump 1 for the cleaning device is provided with a first outlet 111 and a second outlet 112 on the pump body 11. By rotating the impeller 14, it can selectively drive the condensed water 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 layout. A guiding member 152 is arranged inside the drainage cavity. The guiding member 152 can guide the water flow, change the flow trajectory of the condensed water, make it closer to the first outlet 111 or the second outlet 112, thereby improving the drainage efficiency. By setting the guiding member 152, the water flow resistance can be reduced and the turbulence and noise generated by the water flow can be reduced, making the flow of the condensed water in the drainage cavity more orderly and efficient.

[0044] According to some embodiments of the present utility model, the first outlet 111 and the second outlet 112 are respectively open towards the height direction of the pump body 11.

[0045] Specifically, the first outlet 111 and the second outlet 112 are respectively open towards the height direction of the pump body 11, which provides 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 on 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 and enable the condensed water to be discharged more quickly.

[0046] According to some embodiments of the present utility model, the guiding member 152 includes: a body portion 1521, the body portion 1521 extends away from the impeller 14 in the tangential direction of the impeller 14, and a first guiding surface inclined towards the height direction is formed on the top surface of the body portion 1521.

[0047] Specifically, the body portion 1521 extends away from the impeller 14 along the tangent direction of the impeller 14, so that the body portion 1521 can receive the water flow flowing out tangentially from the impeller 14 and guide it to flow in a predetermined direction. A first guiding surface extending towards the height direction in the direction away from the impeller 14 is formed on the top surface of the body portion 1521. Among them, the thickness of the body portion 1521 gradually increases in the direction away from the impeller 14, thereby forming a guiding inclined surface or an arc surface on the top surface of the body portion 1521, which not only enhances the strength and stability of the guiding member 152, but also enables the body portion 1521 to better control the flow direction and speed of the water flow.

[0048] According to some embodiments of the present invention, the guiding member 152 further includes: a guiding portion 1522, the guiding portion 1522 is disposed around the outer periphery of the body portion 1521 and protrudes from the top surface of the body portion 1521, and a second guiding surface extending in the height direction is formed on the guiding portion 1522.

[0049] Specifically, the diversion part 1522 is disposed around the outer periphery of the main body part 1521 and protrudes from the top surface of the main body part 1521. A second diversion surface extending in the height direction is formed on the diversion part 1522. The second diversion surface can further guide the condensed water diverted by the first diversion surface to the first outlet 111 or the second outlet 112, further guiding the flow direction of the condensed water. Through the synergistic effect of the main body part 1521 and the diversion part 1522, the diversion member 152 can effectively guide the flow direction of the condensed water in the pump body 11, making it smoother and more efficient. This not only improves the discharge efficiency of the condensed water but also reduces the vibration and noise problems caused by water flow disorder.

[0050] Wherein, the main body part 1521 can be provided separately or synchronously with the diversion part 1522 to improve the diversion effect.

[0051] According to some embodiments of the present invention, the drainage cavity includes: a confluence cavity, the impeller 14 is disposed on the top of the confluence cavity, and the water inlet 113 is disposed at the bottom of the confluence cavity; a first flow channel 114 and a second flow channel 115, the first flow channel 114 and the second flow channel 115 extend tangentially in the confluence cavity and are respectively communicated with the confluence cavity, and the diversion member 152 is respectively disposed in the first flow channel 114 and / or the second flow channel 115.

[0052] Specifically, by forming the water inlet 113 at the bottom of the confluence cavity, it is convenient to submerge the water inlet 113 below the condensed water level for pumping water. The first flow channel 114 and the second flow channel 115 are respectively communicated with the confluence cavity and extend in the tangential direction of the confluence cavity. By setting the first flow channel 114 and the second flow channel 115 to extend tangentially in the confluence cavity, it helps to guide the condensed water in the confluence cavity into the first flow channel 114 or the second flow channel 115, improving the drainage efficiency. 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 condensed water 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 first flow channel 114 and the second flow channel 115 extend tangentially, which helps to evenly distribute the condensed water into the two flow channels, avoiding vibration and noise problems caused by uneven water flow.

[0053] According to some embodiments of the present invention, the driving pump 1 further includes: a driving device 13, the driving device 13 is disposed on the top of the confluence cavity and is connected to the impeller 14, and the driving device 13 can selectively drive the impeller 14 to rotate forward or backward to selectively introduce the condensed water in the confluence cavity into the first flow channel 114 or the second flow channel 115.

[0054] 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, enabling the pump body 11 to 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 through the driving device 13, the flow direction of the condensed water can be flexibly adjusted to meet different cleaning requirements.

[0055] According to some embodiments of the present invention, the impeller 14 includes: a base 141, the base 141 is arranged at the top of the confluence cavity and is connected to the driving device 13; a first blade 142, the first blade 142 is configured as an arc-shaped blade extending radially, and the first blade 142 is circumferentially spaced on the base 141; 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.

[0056] Specifically, 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 relatively 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 during rotation, which is beneficial to reducing the impact of the blade on the water flow and thus reducing noise. The first blade 142 is circumferentially spaced 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 the predetermined direction, and improving the discharge efficiency of the condensed water. The second blade 143 is arranged at the bottom of the first blade 142, enabling the second blade 143 to further guide the water flow on the basis of the first blade 142 and enhancing the drainage effect of the impeller 14.

[0057] Among them, the radial dimension of the second blade 143 is smaller than that of the first blade 142. When water flow passes through the first blade 142, most of the condensed water is pushed towards the first flow channel 114 or the second flow channel 115, and the remaining condensed water 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 condensed water inside 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 condensed water can be driven to flow through the second blade 143, thereby ensuring the drainage capacity of the pump body 11.

[0058] According to some embodiments of the present invention, the driving pump 1 further includes: a flow blocking portion 151, the flow blocking portion 151 is disposed on the bottom surface of the confluence cavity and on one 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.

[0059] Specifically, the flow blocking portion 151 is disposed at the bottom of the confluence cavity and on one 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 condensed water from flowing into the second flow channel 115, ensuring that the condensed water 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 condensed water from flowing towards the first flow channel 114, so that the condensed water can only be discharged along the second flow channel 115. By precisely controlling the flow of the condensed water 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 condensed water can be accurately guided to the corresponding flow channel and discharged from the pump body 11. By providing 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.

[0060] According to some embodiments of the present invention, first diversion inclined surfaces 1511 extending obliquely from the water inlet 113 towards the first flow channel 114 and second diversion inclined surfaces 1512 extending obliquely from the water inlet 113 towards the second flow channel 115 are respectively formed on both sides of the flow blocking portion 151.

[0061] Specifically, a 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 along 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. A 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 along 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 designs of the first diversion inclined surface 1511 and the second diversion inclined surface 1512 make 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 drainage efficiency of the condensed water is improved.

[0062] According to some embodiments of the present invention, the driving pump 1 further includes: a flow blocking portion 153, which is located between the inlet of the second flow channel 115 and the confluence cavity, and the flow blocking portion 153 protrudes from the inner wall of the confluence cavity.

[0063] Specifically, when the amount of condensed water is insufficient, the liquid level of the condensed water in the confluence cavity is relatively low. When the pump body 11 drains 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. Among them, the gas entering the drainage cavity from the second outlet 112 is at the top of the drainage cavity. By arranging the flow blocking portion 153 between the inlet of the second flow channel 115 and the confluence cavity, and the flow blocking portion 153 protruding from the inner wall of the confluence cavity, the gas at the top of the drainage cavity is blocked by the flow blocking portion 153, weakening 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 and ensuring the water flow circulation capacity of the second flow channel 115.

[0064] In some embodiments, the drive 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 is provided with a first outlet 111. The second pipeline 122 communicates the second flow channel 115 with the outside and is provided with a second outlet 112. The first pipeline 121 and the second pipeline 122 extend along the height direction of the pump body 11 respectively.

[0065] Specifically, the first pipeline 121 and the 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. 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 extend along the height direction of the pump body 11 respectively, 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.
