Description

Water storage tank drainage structure with water flow destruction function

The invention relates to a drainage device, in particular to a water storage tank drainage structure having a water flow destruction function.

The conventional drainage device, the drainage structure in the water storage tank, mainly provides the effect of driving the water in the water storage tank to be discharged outward. For example, the Patent No. TW M482715 of the Republic of China, which is the prior art applied by the applicant of the present application, the drainage structure (including the drainage blade 51, the drainage chamber 46 and the lower cover 41) shown in the second and third figures of the case is installed. The body (not labeled) and other components are mainly used to drive the drainage blades to push the water out of the drainage chamber outward.

However, in actual use, the user finds that the rotation of the drainage blade and the design of the water inlet of the drainage chamber cause the water outside the drainage chamber to be driven during operation, thereby forming the same direction as the rotation direction of the drainage blade. A vortex-like stream of water. Such a flow of water collides with other components in the water storage tank when flowing, or forms a torrent in a corner of the water storage tank, thereby generating noise. This shortcoming should be overcome.

The main object of the present invention is to provide a water storage tank drainage structure having a water flow destruction function, which can destroy the water flow in the water storage tank and prevent the water in the water storage tank from forming eddy current during operation, thereby avoiding noise generation.

According to the present invention, a water storage tank drainage structure having a water flow destruction function is disposed in a water storage tank of a drainage device, and a top of the water storage tank is provided with a mounting plate, and the drainage structure comprises: a lower seat. Mainly composed of a top piece, a middle part and a bottom piece, the top piece is disposed on the mounting plate and under the mounting plate, the middle piece is connected to the bottom part of the top piece, and the bottom piece is connected to the bottom piece The bottom of the middle member forms a drainage chamber, and the top and bottom portions of the bottom member respectively form a water inlet and communicate with the drainage chamber, and an outlet pipe is connected to the bottom member and is spatially connected to one side of the drainage chamber a drive shaft extending through the water inlet of the top of the drainage chamber into the drainage chamber through the top piece and the middle piece; and a drainage blade received in the drainage chamber and connected to the drive shaft Rotating by the driving shaft; wherein the top of the bottom member is provided with a plurality of vertical plates, and the top edge of the vertical plates is higher than the water inlet of the top of the bottom member.

Thereby, by providing the vertical plates on the top of the bottom member, the water flow in the water storage tank can be destroyed, and the water in the water storage tank can be prevented from forming eddy current during operation, thereby preventing generation of noise.

In order to explain the technical features of the present invention in detail, the following preferred embodiments will be described with reference to the drawings, wherein:

As shown in FIG. 1 to FIG. 5, a water storage tank drainage structure 10 having a water flow destruction function according to a preferred embodiment of the present invention is housed in a water storage tank 91 of a drainage device 90, the water storage tank. The top of the 91 is provided with a mounting plate 92. The drainage structure 10 is mainly composed of a lower seat 11, a drive shaft 21 and a drainage blade 31, wherein:

The lower seat 11 is mainly composed of a top member 12, a middle member 14 and a bottom member 16. The top member 12 is disposed on the mounting plate 92 and below the mounting plate 92. The middle member 14 is connected. At the bottom of the top member 12, the bottom member 16 is connected to the bottom of the middle member 14 and defines a drainage chamber 17, and the top and bottom portions of the bottom member 16 respectively form a water inlet 161 to communicate with the drainage chamber 17, The outlet pipe 18 is connected to the bottom member 16 and is spatially connected to one side of the drainage chamber 17.

The drive shaft 21 extends through the water inlet 161 at the top of the drain chamber 17 through the top piece 12 and the middle piece 14 into the drain chamber 17.

The drain vane 31 is housed in the drain chamber 17 and connected to the drive shaft 21, and is rotatable by the drive shaft 21.

The top of the bottom member 16 is provided with a plurality of vertical plates 162, and the top edges of the vertical plates 162 are higher than the water inlet 161 at the top of the bottom member 16. Thereby, it is possible to provide an effect of disturbing and destroying the water flow in the water storage tank 91.

In the present embodiment, the middle member 14 can be manufactured in an upright plate shape, and the top portion of the bottom member 16 is flat. Thereby, the middle member 14 itself can produce the effect of disturbing or destroying the water flow, and the flat top of the bottom member 16 can facilitate the easy entry of water from the water inlet 161 at the top of the drainage chamber 17.

The vertical plates 162 may be arbitrarily disposed when being implemented. However, it is preferable that the vertical plates 162 are parallel to each other and separated by a predetermined distance, and the vertical plates 162 are connected to the middle member 14, and The upright plate 162 is perpendicular to the middle piece 14, and the middle piece 14 spans the water inlet 161 at the top of the drain chamber 17 of the base member 16. With such a combination of structures, the water in the water storage tank 91 can be prevented from generating eddy currents when flowing into the water inlet 161 at the top of the drainage chamber 17, and can only flow along the space between the vertical plates 162. The water inlet 161 at the top of the drain chamber 17 enters the drain chamber 17. In addition, the top edge of the vertical plates 162 may be horizontal or may be inclined downward toward the outside, in the present case, for example, inclined outwardly downward.

The structure of this embodiment has been described above, and the mode of operation of this embodiment will be described next.

As shown in FIG. 3, FIG. 5 and FIG. 6, when the water level in the water storage tank 91 is high to a certain extent and drainage is required, that is, the water level has exceeded the top of the bottom member 16, the water will enter the drainage. In room 17. When draining, the drive shaft 21 is driven by a motor (not shown) to rotate the drain blade 31, and the water located in the drain chamber 17 is pushed toward the outlet pipe 18 outward. At the same time, water located outside the drain chamber 17 is entered by the water inlet 161 at the top of the bottom member 16. By the interference and limitation of the vertical plates 162, it is ensured that the water located outside the drainage chamber 17 does not generate eddy current when entering the water inlet 161 at the top of the bottom member 16, and even if a slight eddy current is generated, it can be borrowed. The vertical plates 162 are destroyed to prevent the formation of eddy currents, and further, noise generation can be reduced.

It should be noted that in the embodiment, the middle member 14 is provided with an inspection hole 141, and the driving shaft 21 is exposed through the inspection hole 141 for inspection. The inspection hole 141 is provided for inspection or maintenance. However, the absence of the inspection hole 141 does not affect the effect of the water flow stop or damage in the present case. Moreover, the height of the vertical plates 162 may be higher than the bottom edge of the inspection hole 141 when the lower seat 11 is located in the water storage tank 91 and the water level is higher than the bottom edge of the inspection hole 141. The vertical plates 162 can still provide the effect of destroying the water flow in the water in the inspection hole 141. However, the present invention is not limited to the height of the vertical plates 162 being higher than the bottom edge of the inspection holes 141.
