Description

Technical Field

[0001] The present invention relates to the drainage technology of an air conditioner drainage device, and particularly refers to a drainage cavity with an effect of destroying eddy currents. Background Art

[0002] A water storage tank drainage structure with a water flow destruction function mainly sets a plurality of vertical plates on the bottom part of its lower seat, and the top edges of these vertical plates are higher than the water inlet at the top of the bottom part. The water flow in the water storage tank is destroyed by these vertical plates to avoid the formation of eddy currents in the water storage tank during operation, thereby avoiding the generation of noise.

[0003] Although the foregoing case can destroy the water flow in the water storage tank so that it does not turn into an eddy current, however, its vertical plates and its lower seat are integrally formed, which is applicable to larger drainage devices. For smaller drainage devices, such as the drainage device of the indoor unit of a split air conditioner, there will be a problem of being too large. In addition, after actual testing by the inventor of this case, it is found that the setting method of the plurality of vertical plates in the foregoing technology is too complicated and needs to be simplified. Moreover, in actual use, after the eddy current is generated, only by setting an appropriate flow disturbance structure at the correct position, it is sufficient to achieve the effect of destroying the eddy current.

[0004] Therefore, how to simplify the flow disturbance structure and where to set an appropriate flow disturbance structure become the problems to be solved by the present invention. Summary of the Invention

[0005] The main object of the present invention is to propose a drainage cavity with an effect of destroying eddy currents, which can destroy the possible eddy currents and hardly form eddy currents.

[0006] Another object of the present invention is to propose a drainage cavity with an effect of destroying eddy currents, the flow disturbance structure of which is simpler than the prior art, and the setting position of the flow disturbance structure can fundamentally destroy the eddy current.

[0007] To achieve the above objects, the present invention proposes a drainage cavity with an effect of destroying eddy currents, which is installed in an air conditioner drainage device. The air conditioner drainage device has a mounting seat, a drainage pump, an impeller and a water collection tank. The drainage cavity with an effect of destroying eddy currents includes: a bottom shell having a water inlet hole and a water outlet hole; and an upper shell combined with the bottom shell to form a chamber therebetween. The impeller is located in the chamber. The upper shell has a through hole, and the impeller has a connecting shaft passing through the through hole and extending upward from above the upper shell. The drainage pump has a driving shaft and is connected to the connecting shaft of the impeller; wherein, the upper shell has a plurality of flow disturbance members, the flow disturbance members extend upward from the top of the upper shell by a predetermined length, and the flow disturbance members are distributed around the through hole.

[0008] Through the arrangement of multiple flow spoilers, the present invention can disrupt the vortices that may form, so that the vortices are hardly formed. In addition, the structure of the flow spoilers of the present invention is simpler than that of the prior art, and the installation position thereof can fundamentally disrupt the vortices.

[0030] In order to illustrate the technical features of the present invention in detail, the following preferred embodiments are given and described in conjunction with the accompanying drawings as follows, wherein:

[0031] As Figures 1 to 5 shown, the present invention illustrates a drainage cavity 10 with a vortex-breaking effect through a first preferred embodiment, which is installed in an air conditioner drainage device 90. The air conditioner drainage device 90 has a mounting base 91, a drainage pump 93, an impeller 95 and a water collecting tank 97. The drainage cavity 10 with a vortex-breaking effect is mainly composed of a bottom shell 11 and an upper shell 21, wherein:

[0032] The bottom shell 11 has a water inlet hole 12 and a water outlet hole 14.

[0033] The upper shell 21 is combined with the bottom shell 11 to form a chamber 18 therebetween. The impeller 95 is located in the chamber 18. The upper shell 21 has a perforation 22. The impeller 95 has a connecting shaft 96 passing through the perforation 22 and extending upward from above the upper shell 21. The drainage pump 93 has a driving shaft 94 and is connected to the connecting shaft 96 of the impeller 95.

[0034] Among them, the upper shell 21 has a plurality of turbulence generating members 24. The turbulence generating members 24 extend upward from the top of the upper shell 21 by a predetermined length, and the turbulence generating members 24 are distributed around the perforation 22 to block and destroy the vortex above the perforation 22. In this first embodiment, three turbulence generating members 24 are taken as an example.

[0035] In actual implementation, each spoiler 24 can be selected to be plate-shaped, and the normal line of its plate surface is perpendicular to the radial direction of the perforation 22, which can have a better effect of destroying the eddy current. However, even if it is not plate-shaped, it can still provide the effect of destroying the eddy current. The present invention is not limited to the spoiler 24 being plate-shaped. The edge of the spoiler 24 is flush with the edge of the perforation 22, so that the destruction can be carried out at the position closest to the eddy current. However, this case is not limited to being flush. The non-flush situation can also provide the effect of destroying the eddy current. In addition, the plate surface of each spoiler 24 can be selected to be tapered from bottom to top, so as to cause greater damage to the eddy current below. This is only an example here and is not limited to being tapered from bottom to top. Other forms are also possible. The heights of the spoilers 24 can be set to be the same, and a partition plate 26 can be further provided at the top of the spoiler 24. The connecting shaft 96 of the impeller 95 is arranged below the partition plate 26. The partition plate 26 has a through hole 27 for the driving shaft 94 of the drainage pump 93 to pass through. The aforesaid heights can be the same or different, and the present invention is not limited to the heights being the same.

[0036] In addition, in this first embodiment, the upper shell 21 can be further provided with a plurality of mounting feet 28 for mounting on the mounting seat 91 and located below the mounting seat 91. However, other mounting methods can also be adopted, and the present invention is not limited to the provision of the mounting feet 28. In addition, the upper shell 21 is recessed with a groove 221 around the perforation 22. A part of the bottom of the spoiler 24 is located in the groove 221. The groove 221 can be used to provide the effect of guiding water, making the water flow into the perforation 22 more smoothly and reducing noise. However, the groove 221 can also not be provided, and the present invention is not limited to the provision of the groove 221.

[0037] The structure of this first embodiment has been described above. Next, the operating state of this first embodiment will be described.

[0038] As Figures 1 to 6 shown, before use, the drainage pump 93 is arranged above the mounting seat 91, the water collecting tank 97 is located below the mounting seat 91, the drainage cavity 10 with the effect of destroying the eddy current of the present invention is also located below the mounting seat 91, and the impeller 95 is located in the chamber 18 and below the mounting seat 91.

[0039] As Figures 1 to 7As shown, when in use, when water enters the water collecting tank 97 and continuously accumulates to a high water level, the water in the water collecting tank 97 will enter the chamber 18 through the water inlet hole 12 until it reaches a predetermined water level height above the perforation 22. Then, the drainage pump 93 is controlled to start operating for drainage. The operation of the drainage pump 93 drives the impeller 95 to rotate in the chamber 18, and pushes the water in the chamber 18 towards the water outlet hole 14 and discharges it outward through a pipe 99. At this time, the water above the perforation 22 will gradually form a vortex due to the water flow driven by the rotation of the impeller 95. However, due to the arrangement of a plurality of the flow disturbing members 24, the water will be continuously disturbed and destroyed by the flow disturbing members 24 before forming a vortex, and it is difficult to form a real vortex.

[0040] In addition, as Figure 7 shown, the water level is higher than the partition plate 26 at this time. The function of the partition plate 26 is to cut off the relationship between the upper and lower parts of the vortex, so that the part of the vortex above the partition plate 26 and the part below the partition plate 26 are cut off and cannot be continuous. As Figure 8 shown, when the water level just abuts on the partition plate 26, the partition plate 26 can provide an effect of suppressing the center of the vortex and reduce noise.

[0041] As can be seen from the above, the present invention can destroy the possible formed vortex, so that the vortex hardly forms. Moreover, the structure of the flow disturbing member 24 of the present invention is simpler than the prior art, and its installation position is near the center position of the vortex, which can fundamentally destroy the vortex.

[0042] As Figure 9 shown, the present invention will illustrate a drainage cavity 10' having an effect of destroying a vortex through a second preferred embodiment. It is generally the same as the foregoing first embodiment, and the difference lies in that:

[0043] In this second embodiment, there is no such partition plate as in the first embodiment.

[0044] When in use, this second embodiment can still provide an effect of destroying a vortex through a plurality of the flow disturbing members 24', and its structure is simpler than that of one embodiment, but it does not have the effect of horizontally cutting the upper and lower parts of the vortex.

[0045] The rest of the structure and the achievable effects of this second embodiment are generally the same as those of the first embodiment, and will not be elaborated here.

[0046] The above is only the content illustrated by the embodiments of the present invention, and it does not limit the protection scope of the claims of the present invention. Any simple changes or equivalent implementations made according to the scope of the claims of the present invention and the content of the specification shall be covered by the protection scope of the claims of the present invention.
