Description

Water storage tank drainage structure with water flow destruction function

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

The conventional drainage device has a drainage structure in the water storage tank, which mainly provides the effect of driving the water in the water storage tank to drain outward. For example, the patent of the Republic of China No. TW M482715, which is the prior art applied by the applicant of this case, the drainage structure shown in Figure 2 and Figure 3 of the case (including the drainage blade 51, the drainage chamber 46 and the lower cover 41 are installed The components (such as the base body (not labeled)) are mainly driven by the motor to rotate the drainage blades to push out the water in the drainage chamber.

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 will 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 current. Such a water flow may collide with other elements in the water storage tank when flowing, or form a torrent in a corner of the water storage tank, thereby forming noise. This disadvantage should be overcome.

The main purpose of the present invention is to provide a water storage tank drainage structure with a water flow destruction function, which can destroy the water flow in the water storage tank, prevent the water in the water storage tank from forming a vortex during operation, and thereby avoid the generation of noise.

The reason is that according to the present invention, a water storage tank drainage structure with a water flow destruction function is provided in a water storage tank of a drainage device. The top of the water storage tank is provided with a mounting plate. The drainage structure includes: a lower seat, It is mainly composed of a top piece, a middle piece and a bottom piece. The top piece is provided on the mounting plate and is located below the mounting plate. The middle piece is connected to the bottom of the top piece and the bottom piece is connected to the bottom piece. The bottom of the middle piece forms a drainage chamber. The top and bottom of the bottom piece respectively form a water inlet to communicate with the drainage chamber. A water outlet pipe is connected to the bottom piece and is spatially connected to one side of the drainage chamber. A drive shaft penetrating through the top piece and the middle piece and extending into the drain room through a water inlet at the top of the drain room; and a drain blade housed in the drain room and connected to the drive shaft, Driven by the drive shaft, the base member is provided with a plurality of vertical plates on the top, and the top edges of the vertical plates are higher than the water inlet on the top of the bottom piece.

Therefore, by setting the vertical plates on the top of the bottom piece, the water flow in the water storage tank can be destroyed, and the water in the water storage tank can be prevented from forming a vortex during operation, thereby preventing the generation of noise.

In order to explain the technical features of the present invention in detail, the following preferred embodiments are described in conjunction with the drawings as follows, wherein:

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

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

The driving shaft 21 penetrates the top piece 12 and the middle piece 14 and protrudes from the water inlet 161 on the top of the drainage chamber 17 into the drainage chamber 17.

The drainage blade 31 is accommodated in the drainage chamber 17 and connected to the driving shaft 21, and can be driven and rotated by the driving shaft 21.

Wherein, a plurality of vertical plates 162 are provided on the top of the bottom piece 16, and the top edges of the vertical plates 162 are higher than the water inlet 161 on the top of the bottom piece 16. Thereby, it is possible to provide interference and destruction effects to the water flow in the water storage tank 91.

In this embodiment, the middle piece 14 can be manufactured into an upright plate shape in practice, and the top of the bottom piece 16 is flat. In this way, the middle piece 14 itself can produce the effect of disturbing or damaging the water flow. The flat shape of the top of the bottom piece 16 can facilitate the easy entry of water from the water inlet 161 on the top of the drainage chamber 17.

In practice, the standing plates 162 can be arbitrarily set. However, it is better that the standing plates 162 are parallel to each other and separated by a predetermined distance, and the standing plates 162 are connected to the middle piece 14. In addition, the The standing plate 162 is perpendicular to the middle piece 14, and the middle piece 14 crosses the water inlet 161 on the top of the drainage chamber 17 of the bottom piece 16. With such a structural combination, when the water in the water storage tank 91 flows into the water inlet 161 at the top of the drainage chamber 17, it is difficult to generate eddy currents, and can only flow to the space along the space between the risers 162. The water inlet 161 at the top of the drainage chamber 17 enters the drainage chamber 17. In addition, the top edges of the risers 162 may be horizontal, or may be inclined downwards outwards. In this case, the outwardly inclined downwards are taken as an example.

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

As shown in Figures 3, 5, and 6, when the water level in the water storage tank 91 is high enough to require drainage, it means that the water level has exceeded the top of the bottom piece 16, and water will enter the drainage Room 17. During drainage, a motor (not shown) drives the driving shaft 21 to drive the drainage blade 31 to rotate, and the water in the drainage chamber 17 is pushed toward the water outlet pipe 18 and outwards. At the same time, the water outside the drainage chamber 17 will enter through the water inlet 161 on the top of the bottom piece 16. With the interference and restriction of these risers 162, it can be ensured that when the water outside the drainage chamber 17 enters the water inlet 161 on the top of the bottom piece 16, no vortex will be generated, and even if a slight vortex is generated, it can be borrowed. The risers 162 are destroyed to prevent the formation of eddy currents and further reduce the generation of noise.

It is worth mentioning that in this embodiment, the middle piece 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 will not affect the effect of blocking or destroying the water flow in this case. In addition, the heights of the standing plates 162 may be higher than the bottom edge of the inspection hole 141 when being set, thereby, 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 standing plates 162 can still provide the effect of destroying the water flow to the water in the inspection hole 141. However, the present invention does not limit the height of the standing plates 162 to be higher than the bottom edge of the inspection hole 141.
