The embodiments described below with reference 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.

[0037] In the related art, the drainage pump for a laundry treatment device generally uses a double - pump structure. One pump drives drainage and the other pump drives circulation. This not only increases the cost but also is not convenient for installation. Therefore, how to optimize the pump body structure so that it can not only achieve drainage but also achieve self - cleaning and is convenient for pump body installation has become an urgent problem in this field.

[0038] The following refers to Figures 1-9 Describe the driving pump for a cleaning device according to an embodiment of the present utility model.

[0039] The driving 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 rotatably 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; wherein, the opening directions of the first outlet 111 and the second outlet 112 are parallel to the axial direction of the impeller 14.

[0040] Specifically, the pump body 11 sucks water into the drainage cavity through the inlet 113 and selectively discharges the condensed water in the drainage cavity through the first outlet 111 or the second outlet 112. Among them, the inlet 113 is arranged at the bottom of the pump body 11, and the pump body 11 is generally arranged at the bottom of the cleaning device. The inlet 113 is arranged at the bottom of the pump body 11 to facilitate sucking the condensed water into the drainage cavity. An impeller 14 is rotatably arranged inside the drainage cavity. The impeller 14 can rotate forward or backward to selectively discharge the condensed water in the drainage cavity from the first outlet 111 or the second outlet 112. The opening directions of the first outlet 111 and the second outlet 112 are respectively parallel to the axial direction of the impeller 14. The first outlet 111 and the second outlet 112 can be respectively arranged at the top of the pump body 11 and open in the height direction. Since the pump body 11 is arranged at the bottom of the cleaning device, setting the opening directions of the first outlet 111 and the second outlet 112 to be respectively parallel to the axial direction of the impeller 14 facilitates the layout of the pump body 11 and is convenient for connecting the first outlet 111 and the second outlet 112 to the relevant pipelines.

[0041] The driving pump 1 for a cleaning device according to the present utility model is provided with a first outlet 111 and a second outlet 112 on the pump body 11. The opening directions of the first outlet 111 and the second outlet 112 are parallel to the axial direction of the impeller 14. Since the pump body 11 is arranged at the bottom of the cleaning device, the first outlet 111 and the second outlet 112 are opened towards the height direction, which facilitates the layout of the pump body 11 and is also convenient for the pump body 11 to be connected to the relevant pipelines through the first outlet 111 and the second outlet 112. By rotating the impeller 14 forward or backward, the condensed water can be selectively driven to be discharged from the first outlet 111 or the second outlet 112, realizing the discharge of the condensed water. The structure is simple and the layout is convenient.

[0042] According to some embodiments of the present utility model, the drainage cavity includes: a confluence cavity, the bottom of the confluence cavity forms the inlet 113; 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 communicate with the confluence cavity, the first outlet 111 communicates with the first flow channel 114, and the second outlet 112 communicates with the second flow channel 115.

[0043] Specifically, by forming a water inlet 113 at the bottom of the confluence cavity, it is convenient to submerge the water inlet 113 below the condensate liquid level, facilitating water pumping. The first flow channel 114 and the second flow channel 115 are respectively connected to the confluence cavity and extend in the tangential direction of the confluence cavity. By arranging the first flow channel 114 and the second flow channel 115 to extend tangentially in the confluence cavity, it helps to guide the condensate 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 connected to the first outlet 111, and the second flow channel 115 is connected to the second outlet 112, enabling the condensate to smoothly discharge through the first outlet 111 or the second outlet 112 after flowing through the first flow channel 114 or the second flow channel 115. This 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 condensate into the two flow channels, avoiding vibration and noise problems caused by uneven water flow.

[0044] According to some embodiments of the present invention, a first pipeline 121 and a second pipeline 122 for communicating the drainage cavity with the outside are provided on the pump body 11. A first outlet 111 is provided on the first pipeline 121, and a second outlet 112 is provided on the second pipeline 122. The extending directions of the first pipeline 121 and the second pipeline 122 are parallel to the axial direction of the impeller 14.

[0045] 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. 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 condensate, making the discharge of the condensate more orderly and controllable, and avoiding the formation of turbulent 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 are respectively parallel to the axial direction of the impeller 14, when the impeller 14 rotates, it can more directly and effectively push the condensate 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.

[0046] According to some embodiments of the present utility model, the driving pump 1 further includes: a flow guiding member 152, the flow guiding member 152 is disposed in the first flow channel 114 and / or the second flow channel 115, at least a part of the flow guiding member 152 located in the first flow channel 114 forms a flow guiding surface extending towards the first pipeline 121, and at least a part of the flow guiding member 152 located in the second flow channel 115 forms a flow guiding surface extending towards the second pipeline 122.

[0047] Specifically, the flow guiding member 152 can be disposed in the first flow channel 114 or in the second flow channel 115. The flow guiding member 152 can be respectively disposed in the first flow channel 114 and the second flow channel 115. By arranging the flow 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 flow guiding member 152 can reduce the occurrence of vortex and turbulence phenomena, thereby improving the discharge efficiency.

[0048] For the flow guiding member 152 located in the first flow channel 114, at least a part of it forms a flow guiding surface extending towards the first pipeline 121, and for the flow guiding member 152 located in the second flow channel 115, at least a part of it forms a flow guiding surface extending towards the second pipeline 122. When the condensed water flows through the flow guiding member 152, it can be guided by the flow guiding surface, and the condensed water smoothly flows towards the corresponding pipeline along the flow guiding surface. The presence of the flow 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 arranging the flow guiding member 152 to control the water flow direction, the flow guiding member 152 reduces the vibration and noise problems caused by water flow disorder, enabling the pump body 11 to operate more smoothly.

[0049] In some embodiments, the flow guiding member 152 includes: a main body portion 1521, the main body portion 1521 extends away from the confluence cavity in the tangential direction of the impeller 14; a flow guiding portion 1522, the flow guiding 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. Wherein, a first flow guiding surface extending towards the height direction is formed on the top surface of the main body portion 1521 in the direction away from the impeller 14, and a second flow guiding surface extending towards the height direction is formed on the flow guiding portion 1522.

[0050] Specifically, the main body portion 1521 is disposed in the first flow channel 114 and / or the second flow channel 115, and extends away from the confluence cavity along the tangential direction of the impeller 14. This enables the main body portion 1521 to receive the condensed water that tangentially flows into the first flow channel 114 or the second flow channel 115 from the confluence cavity and guide it to flow in a predetermined direction. A first guiding surface is formed on the top surface of the main body portion 1521, which extends in the height direction away from the impeller 14. Among them, the main body portion 1521 can be configured such that its thickness gradually increases in the direction away from the confluence cavity, thereby forming a guiding inclined surface or an arc surface on the top surface of the main body portion 1521. This not only enhances the strength and stability of the guiding member 152 but also enables the main body portion 1521 to better control the flow direction and speed of the water flow. The guiding 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 guiding surface extending in the height direction is formed on the guiding portion 1522. The second guiding surface can further guide the condensed water drained through the first guiding 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 portion 1521 and the guiding portion 1522, the guiding 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 drainage efficiency of the condensed water but also reduces the vibration and noise problems caused by water flow disorder.

[0051] 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. 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.

[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 outlet 111 or the second outlet 112 for discharge. 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, and the connection between the impeller 14 and the driving device 13 is 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 pipeline 121 and 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, and the condensed water is pushed towards the second flow channel 115, and the condensed water will finally be discharged from the pump body 11 through the second pipeline 122 and 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] According to some embodiments of the present invention, the impeller 14 includes: a base 141, the base 141 is arranged on 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 blades 142 are 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.

[0054] Specifically, the base 141 is arranged on 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 circumferentially spaced on the base 141, ensuring uniform stress between the blades, reducing turbulence, and enabling the water flow to pass through the blades more smoothly and flow along a predetermined direction, improving the discharge efficiency of the condensed water. The second blade 143 is arranged 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.

[0055] 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 still be driven to flow by the second blade 143, 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, and the flow blocking portion 151 is disposed in the confluence cavity and located between the first flow channel 114 and the second flow channel 115.

[0057] Specifically, the flow blocking portion 151 is disposed in the confluence cavity and located between the first flow channel 114 and the second flow channel 115. When the impeller 14 rotates forward, the flow blocking portion 151 blocks 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 reversely, the flow blocking portion 151 blocks the condensed water from flowing towards the first flow channel 114, making 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 relatively high efficiency during the drainage process. Whether the impeller 14 rotates forward or reversely, the condensed water 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, on both sides of the flow blocking portion 151, a first guiding inclined surface 1511 that extends obliquely from the water inlet 113 towards the first flow channel 114 and a second guiding inclined surface 1512 that extends obliquely from the water inlet 113 towards the second flow channel 115 are respectively formed.

[0059] Specifically, a first diversion inclined surface 1511 is formed on one side of the flow blocking portion 151, extending obliquely from the water inlet 113 towards the first flow channel 114, such that the condensed water in the confluence cavity can 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, extending obliquely from the water inlet 113 towards the second flow channel 115, such that when the impeller 14 rotates in reverse, the condensed water in the confluence cavity can smoothly flow into the second flow channel 115 along the guidance of the second diversion inclined surface 1512. 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 drainage efficiency of the condensed water is improved.

[0060] According to some embodiments of the present utility model, 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 protrudes from the inner wall of the drainage cavity.

[0061] 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 through 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 drainage cavity, the size of the air intake path is reduced, 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.

[0062] Among them, the baffle portion 153 can be integrally formed with the pump body 11 or can be detachably arranged inside the pump body 11.

[0063] The laundry treatment device according to the present invention will be briefly described below.

[0064] The laundry treatment device according to the present invention includes a cleaning device. The cleaning device includes the driving pump 1 described in any one of the above embodiments; a spraying device 17; a heat exchanger and / or a filtering device; a water storage box 16; wherein, the spraying device 17 is connected to the first outlet 111 and has a spraying port arranged towards the heat exchanger and / or the filtering device. The condensed water of the cleaning device flows from the first outlet 111 to the spraying device 17 and is sprayed towards the heat exchanger and / or the filtering device through the spraying port, and then flows to the water storage box 16 from the second outlet 112.

[0065] The laundry treatment device according to the present invention can be configured as a dryer, a washing machine or a washing and drying integrated machine. The heat exchanger can be an evaporator.
