It

[0008]

[Embodiment of device]

  Embodiments of the present invention will be described below with reference to the drawings.   2 to 4 show one type of air conditioning equipment discharge provided by a relatively good embodiment of the present invention. A water pump 10 is shown. Mainly one upper housing 11 and one lower housing 2 It is composed of one and one sealing material 31, and one pumping impeller 41.

[0009]   The upper housing 11 has an upper part extending upward and forming a single connecting tube 12. The bottom surface of the upper housing 11 is gradually lowered from the center toward the outside.   The lower housing 21 is connected to the upper portion so as to correspond to the shape of the upper housing 11. It has a rim 22 and is thereby joined to the upper housing 11. Also inside One hollow chamber 24 is formed. The bottom of the lower housing 21 extends downward One suction pipe 26 communicating with the hollow chamber 24 is formed, and the diameter of the suction pipe 26 is It is gradually increasing from bottom to top. From the side of the lower housing 21 One discharge pipe 28 extends outward and communicates with the hollow chamber 24.

[0010]   The sealing material 31 is provided on the mating surface between the upper housing 11 and the lower housing 21. It is installed and seals the mating surface.   The pumping impeller 41 is installed in the hollow chamber 24 and has one shaft core 42, The upper end extends into the connecting pipe 12, and the bottom end extends into the suction pipe 26. The axis At the upper end of the core 42, one connecting tank 421 is recessed inward, so that It can be connected to the motor rotating shaft 51. The bottom of the shaft core 42 has a cone 42 with a thin bottom and a thick top. 3 is formed, and the peripheral surface of the cone 423 is slightly recessed inward at a predetermined arc degree. And one reinforcing wall 425 that protrudes outward in a ring shape at the middle position of the shaft core 42. And the diameter of the reinforcing wall 425 is larger than the inner diameter of the connecting tube 12. The shaft core 42 Is connected to one board 44 corresponding to the position of the hollow chamber 24. The top and bottom surfaces have some vanes 46 that are equiangularly distributed. The blade 46 is a flat blade. The blades 46 located on the upper surface of the board 44 extend outward from the reinforcing wall 425. There is. The blades 46 located on the lower surface of the board body 44 are full blades 461, half blades 463, And small blades 465, of which all blades 461 are slightly L-shaped and 4 and the pyramid 423, and extends downward to a predetermined length. Half blade 46 3 is located on the board 44, and one end thereof is connected to the cone 423. Small feather 46 5 is located on the board 44 and is separated from the cone 423 by a predetermined distance. The whole blade 4 61 is located on the board 44 and the height of the half blades 463 and the small blades 465. The same is true.

[0011]   As shown in FIG. 4, when the present embodiment is used, the pumping impeller is driven by an externally connected motor. When the pumping impeller 41 rotates by controlling the rotation of the pump 41, it is positioned in the suction pipe 26. The generated water is agitated by the blades 46 and discharged to the outside through the discharge pipe 28.

[0012]   During the process of operation, the bottom surface of the cone 423 of the shaft core 42 is dented inward by a predetermined degree of arc. Therefore, the space around it is more transparent than the conventional surface that is not recessed inward. Large, which allows it to contain (or suck in) more water, making it an arcuate surface Makes the water flow smoother. In other words, the water absorption and drainage efficiency of the structure is further Is good,

[0013]   Furthermore, the design of the bottom surface of the upper housing 11 (the height gradually decreases from the center to the outside) The vortex reaction that occurs when water is moved by the blades 46 Can be offset. As can be seen from FIG. 5, in (A) state (conventional state) And, the space between the swirl and the upper housing 11 '' (i.e., the space where air is present). Is relatively large, but under the (B) state (that is, the state of the present invention), the swirl The space between the housing and the upper housing 11 is relatively small, so there is relatively little air, The noise generated is relatively low.

[0014]   FIG. 6 shows another type of pumping impeller 41 'structure, which is similar to that shown in FIG. It's similar. The difference is the shape of the cone 423 ', but with the same effect.   Through the above description, the present invention certainly has a better function, and the structure is It is clearly different from the conventional one and it has a clear understanding that it has industrial practicality, The application is submitted here based on the law because it meets the requirements for the utility model.
