Detailed Description
To illustrate the technical features of the present invention in detail, the following preferred embodiments are described in conjunction with the drawings, wherein:
as shown in fig. 1 to 7, a first preferred embodiment of the present invention provides a drainage impeller 10 with an annular groove, which mainly comprises a shaft 11 and an annular bottom plate 21, wherein:
the shaft 11 has a connecting slot 12 at the top end for connecting a driving shaft (not shown) to be driven to rotate, and the shaft 11 extends radially outward to form a plurality of main blades 14 in the shape of vertical walls.
The annular bottom plate 21 is disposed at the bottom of the main blades 14, and the annular bottom plate 21 is spaced from the shaft center 11 by a predetermined distance, so that a plurality of hollow portions 22 are formed among the shaft center 11, the main blades 14 and the annular bottom plate 21, and the annular bottom plate 21 has a plurality of sub-blades 24 extending outward along the radial direction of the shaft center 11.
The annular bottom plate 21 has an annular wall 26 extending upward along an outer edge thereof, a shoulder plate 27 extending outward from a top edge of the annular wall 26, the shoulder plate 27 having an upward top surface, an outer annular wall 28 extending downward from an outer edge of the shoulder plate 27, and a blocking wall 29 extending upward from an outer edge of the shoulder plate 27.
In addition, the outer annular wall 28, the shoulder plate 27 and the annular wall 26 surround to form an annular groove 281 with a downward opening.
In the first embodiment, the bottom edge of the outer annular wall 28 is substantially flush with the virtual plate body extending outward from the annular bottom plate 21, and the upper surface of the joint of the annular wall 26 and the shoulder plate 27 is arc-shaped. The top edge of the baffle wall 29 is undulated along the periphery of the annular bottom plate 21, the bottom edge of the outer annular wall 28 is undulated along the periphery of the annular bottom plate 21, and the high points of the undulated top edge of the baffle wall 29 vertically correspond to the high points of the undulated bottom edge of the outer annular wall 28, and the low points vertically correspond to each other. In the main blades 14 and the sub-blades 24, the top edge of some blades is higher than the top surface of the shoulder plate 27 and is flush with the top edge of the blocking wall 29.
The structure of the present first embodiment is explained above, and the operation state of the present first embodiment is explained next.
As shown in fig. 5, before use, the drain impeller 10 is assembled inside a drain pump 90, and a water inlet 91 is provided below the drain pump 90 and a drain port 92 is provided at one side thereof.
As shown in fig. 6, when the drainage is started, the drainage impeller 10 is driven to rotate, and at this time, water enters from below the drainage pump 90, and the water level is in a low water level state.
As shown in fig. 7, as the water is sucked into the drain pump 90 continuously with the rotation of the drain impeller 10, the water level is continuously raised, since the water is just discharged, and the water is just sucked into the drain pump 90, before the speeds of the inlet water and the outlet water are not balanced, the speed of the inlet water is higher than that of the outlet water, which causes the water level to be continuously raised to be higher than the annular bottom plate 21, and to flow into the annular bottom plate 21 through the plurality of hollows 22, and to be moved to the annular wall 26 and blocked by the centrifugal force generated by the rotation of the drain impeller 10, in the state of fig. 7, the water passes through the annular wall 26 and flows to the shoulder plate 27 and is blocked by the blocking wall 29, in which the water higher than the annular wall 26 does not flush out of the drain impeller 10 and directly hits the inner wall of the drain pump 90, and thus no vibration or noise is generated based on this point, at this time, water begins to be discharged from the water outlet 92. Since the annular bottom plate 21 and the shoulder plate 27 have different heights, the water is in different depths at the two positions, which makes the water not directly rushing through when flowing from the annular bottom plate 21 to the shoulder plate 27, thereby achieving the effect of providing a slow speed to the water. In addition, during the water level rising process, water and air bubbles enter the annular groove 281 from the bottom of the annular bottom plate 21, and the annular groove 281 plays a role of storing water and air bubbles at the stage of the initial water intake, so that the chance of the air bubbles and water hitting the inner wall of the drain pump 90 can be reduced, and the noise and vibration can be reduced.
As shown in fig. 8, after the drain impeller 10 is operated for a period of time, the speeds of the inlet and outlet of the drain pump 90 are balanced, and the inside of the drain pump 90 is almost full, so that there is no problem of air bubbles or water impact, and a stable drain state is achieved without noise or vibration.
In the first embodiment, the top edge of the blocking wall 29 and the bottom edge of the outer annular wall 28 are wavy, so as to generate a slight driving effect on water when the drainage impeller 10 rotates, thereby cooperating with the main blades 14 and the sub blades 24 to drive water to rotate in the drainage pump 90. In addition, the main blades 14 and the sub-blades 24 are higher than each other, so that the height of the blocking wall 29 can be matched to drive water.
Therefore, the present invention can reduce or even eliminate the noise and vibration of the water that may impact the inner wall of the drainage pump 90 in the initial stage of the drainage stage by the cooperation of the retaining wall 29 and the shoulder plate 27 and the arrangement of the annular groove 281, thereby solving the problem of the prior art.
As shown in fig. 9 to 10, a second preferred embodiment of the present invention provides a drainage impeller 10' with an annular groove, which is basically the same as the first embodiment, except that:
the top edge of the retaining wall 29 'is horizontal along the periphery of the annular base 21' and the bottom edge of the outer annular wall 28 'is horizontal along the periphery of the annular base 21', rather than undulating as in the first embodiment described above.
The top surfaces of the plurality of main blades 14 ' and the plurality of sub blades 24 ' are flush with the top surface of the shoulder plate 27 '.
In the second embodiment, the top edge of the retaining wall 29 ' and the bottom edge of the outer annular wall 28 ' are horizontal, so that the water-driving effect is not generated when the impeller 10 ' rotates, but the impact on water can be greatly reduced, and the noise reduction effect can be generated. In addition, the top surfaces of the main blades 14 'and the sub blades 24' are flush with the top surface of the shoulder plate 27 ', so that the water discharge impeller 10' can rotate with less interference to water than the first embodiment, and the noise reduction effect can be also generated.
The remaining structure and the effect achieved by the second embodiment are the same as those of the first embodiment, and will not be described again.
As shown in fig. 11 to 12, a third preferred embodiment of the present invention provides a drainage impeller 10 "with an annular groove, which is basically the same as the first embodiment, except that:
the shoulder plate 27 "is provided with a plurality of balance holes 271", the plurality of balance holes 271 "are disposed at equal angles with respect to the shaft center 11", and the plurality of balance holes 271 "are spatially communicated with the annular groove 281". In addition, each of the balance holes 271 "is located at the end of a main vane 14" or a sub-vane 24 ".
In practical use, the balance holes 271 "of the third embodiment allow water on the surface of the shoulder plate 27" to communicate with water in the annular groove 281 "so as to balance the pressures on both sides, thereby reducing vibration of the discharge impeller 10" caused by different pressures between the upper and lower sides during operation, and further reducing noise.
The remaining structure and the effect achieved by the third embodiment are substantially the same as those of the first embodiment, and will not be described again.
Of course, the present invention can have other embodiments, and those skilled in the art can make various corresponding changes and modifications according to the present invention without departing from the spirit and the essence of the present invention, and these corresponding changes and modifications should fall within the protection scope of the claims of the present invention.
