中國CN 104514725A號專利，揭露了一種空調裝置用的排水泵，該案其主要的特徵在於其電動機的下部殼體具有蓋部，以及支撐電動機的圓筒形狀的外筒部和內筒部，而設於外筒部的排水用縫隙具有將殘留水向外部引導的導向部件；前述習知專利亦揭露了蓋部的排水用縫隙具有將殘留水向外方引導的導向部件。雖然此案可藉由外筒部來遮蔽其內筒部的內筒縫隙，藉此遮斷馬達運轉的部分噪音，然而，此案件的排水路徑過長，增加了殘留水排出的困難性。China’s patent No. CN 104514725A discloses a drainage pump for air conditioners. The main feature of this case is that the lower housing of the motor has a cover, and a cylindrical outer and inner cylinder that supports the motor. The drainage slit provided in the outer cylinder portion has a guide member that guides residual water to the outside; the aforementioned conventional patent also discloses that the drainage slit of the cover portion has a guide member that guides the residual water to the outside. Although this case can cover the inner cylinder gap of the inner cylinder part by the outer cylinder part, thereby blocking part of the noise of the motor operation, however, the drainage path in this case is too long, which increases the difficulty of discharging residual water.

該下殼體11，底部形成一吸水口12，側面形成一排水口14。The lower casing 11 has a water inlet 12 at the bottom and a water outlet 14 at the side.

該主殼體21，實質呈圓筒狀，設於該下殼體11上方，並且與該下殼體11之間形成一排水室18，該吸水口12及該排水口14均在空間上連通於該排水室18，且該主殼體21具有一馬達容室22以及一溢水容室24。該排水室18內設有一排水葉片19，該馬達容室22內係容置一馬達23，該溢水容室24位於該馬達容室22下方，且該主殼體21具有一底板211，該底板211具有一穿孔212而在空間上與該排水室18相通，該排水葉片19係藉由該穿孔212來與該馬達23之驅動軸連接，由於馬達23具有驅動軸乃公知常識，因此容不對此贅述。該主殼體21外表面設有複數卡塊213。The main casing 21 is substantially cylindrical and is disposed above the lower casing 11 and forms a drainage chamber 18 between the lower casing 11. The water suction port 12 and the drainage port 14 are all spatially connected In the drainage chamber 18, the main housing 21 has a motor chamber 22 and an overflow chamber 24.

The drainage blade 19 is connected to the drive shaft of the motor 23 through the perforation 212. Since the motor 23 has a drive shaft, it is common knowledge, so it is not to be tolerated Repeat. A plurality of clamping blocks 213 are provided on the outer surface of the main housing 21.

該蓋體31，蓋設於該主殼體21，而覆蓋該馬達容室22。該蓋體31係向外向下延伸複數勾部313，並藉由該複數勾部313勾住該複數卡塊213而固定於該主殼體21。The cover 31 covers the main housing 21 and covers the motor compartment 22. The cover body 31 extends a plurality of hook portions 313 outwards and downwards, and is fixed to the main housing 21 by hooking the plurality of clamping blocks 213 with the plurality of hook portions 313.

其中，由該主殼體21之該底板211向上延伸複數隔牆26而位於該溢水容室24內，該複數隔牆26呈弧狀且圍合該穿孔212而呈一圓筒狀結構，且兩兩前述隔牆26之間相隔預定距離而形成一縫隙27，該複數隔牆26之間所形成的該複數縫隙27相對於該圓筒狀結構的軸心呈等角排列，且該複數隔牆26沿各該縫隙27之一邊緣向外斜向延伸而形成複數導流板261，各該導流板261於本實施例中係設置為弧狀，並且跨越各該縫隙27而延伸至各該縫隙27另一邊緣，各該導流板261與各該縫隙27另一邊緣的隔牆26相隔預定距離並形成向外開口的一流道271，其中，該複數隔牆26所圍合的空間係藉由該複數縫隙27經由該複數流道271與外界在空間上相通。該複數導流板261相對於該圓筒狀結構的軸心呈順時針方向延伸以及排列。Wherein, a plurality of partition walls 26 extend upward from the bottom plate 211 of the main housing 21 and are located in the overflow chamber 24. The plurality of partition walls 26 are arc-shaped and surround the perforation 212 to form a cylindrical structure, and two A gap 27 is formed between the two partition walls 26 by a predetermined distance, the plurality of gaps 27 formed between the plurality of partition walls 26 are arranged at an equal angle with respect to the axis of the cylindrical structure, and the plurality of partition walls 26 along an edge of each of the slits 27 extends obliquely outward to form a plurality of deflectors 261, each of the deflectors 261 in this embodiment is arranged in an arc shape, and extends across each of the slits 27 to each At the other edge of the slit 27, each of the deflectors 261 is separated from the partition wall 26 at the other edge of the slit 27 by a predetermined distance and forms a flow path 271 that opens outward, wherein the space enclosed by the plurality of partition walls 26 is The plurality of slits 27 are in spatial communication with the outside through the plurality of flow channels 271. The plural deflectors 261 extend clockwise with respect to the axis of the cylindrical structure and are arranged.

其次，由該主殼體21之該底板211向上延伸複數擋板25，各該擋板25對應於各該縫隙27而位於各該縫隙27與該穿孔212之間，且一該擋板25與其對應的一該縫隙27相隔預定距離而不會將該縫隙27封閉。該複數擋板25可以產生阻擋聲音的效果，使該圓筒狀結構內的聲音不會直接由該複數縫隙27通過，而是會受到該複數擋板25的擋止。因此，在設置上，各該擋板25的橫向寬度可以設置為不小於一該縫隙27的寬度，例如，於本實施例中係設置為相同於一該縫隙27的寬度。Next, a plurality of baffles 25 extend upward from the bottom plate 211 of the main housing 21, each baffle 25 corresponds to each of the slits 27 and is located between each of the slits 27 and the perforation 212, and a baffle 25 and its Correspondingly, the gap 27 is separated by a predetermined distance without closing the gap 27. The plurality of baffles 25 can produce a sound blocking effect, so that the sound in the cylindrical structure will not directly pass through the plurality of slits 27, but will be blocked by the plurality of baffles 25. Therefore, in terms of installation, the lateral width of each baffle 25 may be set to be no less than the width of one of the slits 27, for example, in this embodiment, it is set to be the same as the width of one of the slits 27.

此外，該主殼體21具有一外壁28，圍繞於該複數隔牆26所形成的圓筒狀結構之外而與該圓筒狀結構之間形成一外環區29，該外壁28具有複數溢水孔281，於本實施例中係以三個為例，該複數溢水孔281在設置位置上係對應位於各該卡塊213的下方，此乃係由於模具設置上為了開模方便，因此將溢水孔281與卡塊213以上下對應的位置來設置。該複數溢水孔281之孔緣底端係位於該主殼體21之底板211，而與該外環區29在空間上相通。此外，各該溢水孔281係設置為靠近於各該導流板261，此處之靠近係指，一該溢水孔281在相鄰的二該導流板261之間，係較靠近於其中一該導流板261，而不會剛好位於兩者的中間位置。In addition, the main housing 21 has an outer wall 28 that surrounds the cylindrical structure formed by the plurality of partition walls 26 and forms an outer ring region 29 with the cylindrical structure, the outer wall 28 has a plurality of overflows In this embodiment, three holes are taken as an example. The plurality of overflow holes 281 are correspondingly located under each of the clamping blocks 213 in the installation position. This is because the mold is provided for easy opening of the mold, so the overflow The hole 281 is provided at a position corresponding to the vertical direction of the block 213. The bottom edges of the plurality of overflow holes 281 are located on the bottom plate 211 of the main housing 21 and are in spatial communication with the outer ring area 29. In addition, each of the overflow holes 281 is disposed close to each of the deflectors 261, and the close here means that one of the overflow holes 281 is between two adjacent deflectors 261, which is closer to one of them The deflector 261 will not be located in the middle of the two.

如第6圖所示，在實際實施時，該複數隔牆26可以設置為高度相同，且該複數導流板261的高度與該複數隔牆26相同，此外，該複數擋板25的度也可以設置為與該複數隔牆26相同，該馬達23底部係抵於該複數隔牆26、該複數擋板25以及該複數導流板261頂緣，亦即，該複數隔牆26的高度即為該溢水容室24的高度，而該複數隔牆26的頂緣上方即為該馬達容室22。此外，如第3圖所示，該複數隔牆26中，有部分的隔牆26頂部向上延伸而形成二凸柱262，而該馬達23底部則具有二凹穴232，該馬達23底部抵於該複數隔牆26以及該複數導流板261頂緣時，該二凸柱262係嵌入於該二凹穴232，藉以產生定位的效果。而凸柱262與凹穴232的數量，可以多於二個，藉此來增加定位的效果。As shown in FIG. 6, in actual implementation, the plurality of partition walls 26 may be set to have the same height, and the height of the plurality of deflectors 261 is the same as that of the plurality of partition walls 26. In addition, the degree of the plurality of baffles 25 is also It can be set to be the same as the plurality of partition walls 26, and the bottom of the motor 23 is pressed against the top edges of the plurality of partition walls 26, the plurality of baffles 25, and the plurality of deflectors 261, that is, the height of the plurality of partition walls 26 is It is the height of the overflow chamber 24, and the top of the plurality of partition walls 26 is the motor chamber 22. In addition, as shown in FIG. 3, in the plurality of partition walls 26, some of the partition walls 26 extend upward to form two convex columns 262, and the bottom of the motor 23 has two recesses 232, and the bottom of the motor 23 resists When the top edges of the plurality of partition walls 26 and the plurality of deflectors 261, the two convex posts 262 are embedded in the two concave holes 232, so as to produce a positioning effect. The number of the convex posts 262 and the concave holes 232 can be more than two, thereby increasing the positioning effect.

前述的複數隔牆26以及擋板25的高度亦可以設置為彼此不同，只是要注意到其支撐馬達23的穩定性。The heights of the aforementioned plurality of partition walls 26 and the baffle 25 can also be set to be different from each other, just to pay attention to the stability of the supporting motor 23.

以上說明了本發明之架構，接下來說明本發明之操作狀態。The structure of the present invention has been described above, and then the operating state of the present invention will be described.

如第2圖所示，在正常運轉的狀況下，該馬達23係驅轉該排水葉片19轉動，藉以將該排水室18內的水由該排水口14向外排出。在一般狀況下，該排水口14通常會連接一排水管(圖中未示)，來將水向外引流排出，由於連接排水管乃是極為習知的技術，容不再以圖式表示之。As shown in FIG. 2, under normal operating conditions, the motor 23 drives the drain blade 19 to rotate, thereby draining the water in the drain chamber 18 from the drain opening 14. Under normal circumstances, the drainage port 14 is usually connected to a drainage pipe (not shown in the figure) to drain the water outwards. Since connecting the drainage pipe is a very well-known technology, the capacity is no longer shown in the diagram .

如第2圖及第3圖配合第5圖及第6圖所示，在該馬達23關閉或停止運轉後，該排水葉片19即停止轉動，此時，該排水管內的水會有部分逆流回該排水室18內。由於該排水室18內設置有排水葉片19，因此逆流回來的水不會太快的進入該排水室18內，而是慢慢的進入，並再由該穿孔212進入該溢水容室24的圓筒狀結構內。位於該圓筒狀結構內的水即會經由該複數縫隙27再經由該複數流道271向外流至該外環區29內。接著，藉由一該溢水孔281係靠近於一該導流板261，也就是靠近於一該流道271的開口，可以使得由該複數流道271流出的水可以快速的流至各該溢水孔281而向外流出。As shown in FIG. 2 and FIG. 3 in conjunction with FIG. 5 and FIG. 6, after the motor 23 is turned off or stopped, the drain blade 19 stops rotating. At this time, the water in the drain pipe will partially reverse flow Return to the drainage chamber 18. Because the drainage vane 19 is provided in the drainage chamber 18, the water flowing backward will not enter the drainage chamber 18 too quickly, but enter slowly, and then enter the circle of the overflow chamber 24 through the perforation 212 Inside the tubular structure. The water located in the cylindrical structure will flow out through the plurality of slits 27 and then through the plurality of flow channels 271 to the outer ring region 29. Then, by the overflow hole 281 being close to the deflector 261, that is, close to the opening of the flow channel 271, the water flowing out of the plurality of flow channels 271 can quickly flow to each overflow The hole 281 flows out.

在決定該溢水孔281的數量時，是可以視實際需求而定的，以本案而言，三個溢水孔281靠近於三個導流板261已足夠發揮溢流洩水的效果，因此不需要設置四個溢水孔281。而在本案的三個溢水孔281的情況下，各該溢水孔281仍然是靠近於一該流道271的開口，而能發揮出縮短流道271的效果，進而，可以快速的排水，使得逆流的水不會因為無法排出而快速的在該圓筒狀結構內累積而水位升高至傷害該馬達23。當然，若決定設置四個溢水孔，也是可以依本案第5圖的溢水孔281與各該導流板261的對應關係，來將各個溢水孔與各該導流板261對應設置。When deciding the number of the overflow holes 281, it can be determined according to actual needs. In this case, the three overflow holes 281 close to the three deflectors 261 are enough to exert the effect of overflow and drainage, so there is no need Set four overflow holes 281. In the case of the three overflow holes 281 in this case, each of the overflow holes 281 is still close to an opening of the flow channel 271, which can exert the effect of shortening the flow channel 271, and further, can quickly drain the water, making the counter current The water does not quickly accumulate in the cylindrical structure because it cannot be discharged, and the water level rises to hurt the motor 23. Of course, if it is decided to provide four overflow holes, the corresponding relationship between the overflow holes 281 and the deflectors 261 in FIG. 5 of the present case can be used to set the respective overflow holes to the deflectors 261.

由上可知，藉由本案的擋板25擋止聲音由縫隙27直接穿出的效果，以及該複數導流板261能對穿過該縫隙27的聲音做正面的阻擋之外，在該複數導流板261外還具有該主殼體21的外壁28，該外壁28也能發揮擋住聲音的效果，因此，該複數導流板261以及該外壁28即能發揮多重的隔絕噪音的效果，其減噪效果極佳。此外，藉由本案的溢水孔281靠近導流板261的設置關係，仍然具有較習知技術而言更縮短流道271，使得位於該溢水容室24內的水能快速的流出的效果。綜上，本發明能同時兼顧縮短流道271以及減低噪音的雙重效果，較前述習知技術而言，具有功效上的增進。It can be seen from the above that the baffle 25 in this case blocks the effect of the sound directly passing through the slit 27, and the complex baffle 261 can positively block the sound passing through the slit 27. There is also an outer wall 28 of the main casing 21 outside the flow plate 261. The outer wall 28 can also play the role of blocking sound. Therefore, the plurality of deflectors 261 and the outer wall 28 can exert multiple noise isolation effects, which reduces The noise effect is excellent. In addition, due to the arrangement relationship of the overflow hole 281 close to the deflector 261 in this case, it still has the effect of shortening the flow path 271 compared with the conventional technology, so that the water located in the overflow chamber 24 can quickly flow out.
