Description
技术领域technical field
本发明涉及包括尘埃回旋分离部的除尘(集尘)装置。The present invention relates to a dust removal (dust collection) device including a dust cyclone separation unit.
背景技术Background technique
现有的这种除尘装置广泛用于吸尘器，其包括：具有气流吸入部和气流吹出部的主体壳和设置于该主体壳内的、将从气流吸入部吸入到主体壳内的气流从气流吹出部排出到主体壳外的风扇。而且，是包括回旋单元的结构，该回旋单元使通过该风扇经由气流吸入部吸入到主体壳内的气流回旋，将该吸入气流中所含的尘埃分离(例如，参照专利文献1)。The existing dust removal device is widely used in vacuum cleaners, which includes: a main body shell with an airflow suction part and an airflow blowout part, and an airflow that is sucked into the main body shell from the airflow suction part and blown out from the airflow. A fan that discharges partially to the outside of the main case. Furthermore, it is a structure including a swirl unit that swirls the airflow sucked into the main body case by the fan through the airflow suction portion, and separates dust contained in the sucked airflow (for example, refer to Patent Document 1).
在上述现有例中，当驱动风扇时，首先，气流从气流吸入部吸入到主体壳内，接着，该气流通过回旋单元而回旋，由此，该吸入气流中所含的尘埃被分离、除尘。In the above-mentioned conventional example, when the fan is driven, first, the airflow is sucked into the main body case from the airflow suction part, and then the airflow is swirled by the swirl unit, whereby the dust contained in the suction airflow is separated and dedusted. .
例如，如果是吸尘器，则可动操作的吸入喷嘴与主体壳的气流吸入部连接，通过将该吸入喷嘴移动到想要清扫的部分，就能够进行广泛区域的除尘。For example, in the case of a vacuum cleaner, a movably operated suction nozzle is connected to the airflow suction portion of the main body case, and by moving the suction nozzle to a part to be cleaned, dust can be removed over a wide area.
但是，在不使用可动操作的吸入喷嘴的除尘装置，即将主体壳放置的状态下收集其附近的尘埃的除尘装置时，由于回旋单元只有一个，所以只能对狭小范围的尘埃进行除尘。因此，除尘效果差。However, in the case of a dust removal device that does not use a movable suction nozzle, that is, collects dust near the main body case, since there is only one swivel unit, it can only remove dust in a narrow range. Therefore, the dust removal effect is poor.
于是，本发明的目的在于提高除尘效果。Therefore, the object of the present invention is to improve the dust removal effect.

In addition, a dust swirling and separating part is included which swirls the air flow sucked into the main body case through the air flow suction part by the fan, and separates the dust contained in the sucked air flow.

如上所述，在尘埃回收箱内设置有循环风路，从形成于多个回旋单元的多个尘埃排出口吹出的气流的吹出方向与循环风路的循环方向相同，由此能够提高除尘效果。As mentioned above, a circulating air path is provided in the dust collection box, and the blowing direction of the airflow blown from the plurality of dust outlets formed in the plurality of swirling units is the same as the circulation direction of the circulating air path, thereby improving the dust removal effect.

由此，能够抑制从各个回旋单元的尘埃排出口吹出的气流进入其他回旋单元的尘埃排出口，作为其结果，各个回旋单元的除尘效果提高。Thereby, it can suppress that the airflow blown out from the dust discharge port of each swirl unit enters the dust discharge port of another swirl unit, As a result, the dust removal effect of each swirl unit improves.

具体实施方式Detailed ways
下面，参照附图对本发明的一个实施方式进行说明。Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
(实施方式)(implementation mode)
图1是除尘装置的立体图。如图1所示，在箱状的主体壳1的两侧面设置有气流吸入部2，在上方设置有气流吹出部3。Fig. 1 is a perspective view of a dust removal device. As shown in FIG. 1 , an airflow suction part 2 is provided on both side surfaces of a box-shaped main body case 1 , and an airflow blowout part 3 is provided above.
如图2所示，在主体壳1内设置有风扇4，当驱动该风扇4时，主体壳1外侧的空气从气流吸入部2被吸入，接着，通过尘埃回旋分离部5，之后通过过滤器6。As shown in FIG. 2, a fan 4 is provided inside the main body case 1. When the fan 4 is driven, the air outside the main body case 1 is sucked in from the air flow suction part 2, then passes through the dust swirling separation part 5, and then passes through the filter. 6.
通过了过滤器6的气流通过风扇4，之后，从气流吹出部3向主体壳1之外吹出。The airflow passing through the filter 6 passes through the fan 4 and is then blown out of the main body case 1 from the airflow outlet part 3 .
在此，在从气流吸入部2吸入到尘埃回旋分离部5内的气流中含有尘埃。气流中所含的尘埃中，大的尘埃通过尘埃回旋分离部5回旋而被分离。然后，分离出的尘埃被回收到图3所示的尘埃回收箱7，堆积在处于尘埃回收箱7的下部的抽出托盘7a。该抽出托盘7a能够从主体壳1上装卸，能够将尘埃简单地丢掉。Here, dust is contained in the airflow sucked from the airflow suction part 2 into the dust cyclone separation part 5 . Among the dust contained in the airflow, the large dust is swirled by the dust swirl separation unit 5 to be separated. Then, the separated dust is recovered to the dust recovery box 7 shown in FIG. This drawer tray 7a can be attached and detached from the main body case 1, and dust can be easily thrown away.
另外，从气流吸入部2吸入到主体壳1内的气流所含的尘埃中，小的尘埃通过尘埃回旋分离部5，之后在过滤器6除尘。In addition, among the dust contained in the airflow sucked into the main body case 1 from the airflow suction part 2 , the small dust passes through the dust cyclone separation part 5 and is then removed by the filter 6 .
然后，除去了尘埃的气流通过风扇4，之后从气流吹出部3向主体壳1外吹出。Then, the airflow from which the dust has been removed passes through the fan 4 and is then blown out of the main body case 1 from the airflow outlet part 3 .
接着，对尘埃回旋分离部5详细地进行说明。如图4、图5所示，尘埃回旋分离部5为在上下方向排列多个回旋单元8的结构。Next, the dust cyclone separation unit 5 will be described in detail. As shown in FIGS. 4 and 5 , the dust swirling and separating unit 5 has a structure in which a plurality of swirling units 8 are arranged in the vertical direction.
即，如该图4、图5所示，回旋单元8是在上下方向排列各个回旋单元8的回旋壁9的结构。各个回旋单元8的回旋壁9的侧面部成为与设置于主体壳1的侧面的气流吸入部2连结的状态。各个回旋单元8的回旋壁9的轴向为水平方向，气流吸入部2在主体壳1的前面侧开口。That is, as shown in FIG. 4 and FIG. 5 , the swirling units 8 have a structure in which the swirling walls 9 of the respective swirling units 8 are arranged in the vertical direction. The side surface of the swirl wall 9 of each swirl unit 8 is connected to the airflow suction portion 2 provided on the side surface of the main body case 1 . The axial direction of the swirl wall 9 of each swirl unit 8 is a horizontal direction, and the airflow suction portion 2 is opened on the front side of the main body case 1 .
因此，当驱动风扇4时，从气流吸入部2进入尘埃回旋分离部5的气流通过回旋单元8而回旋，通过该回旋，从气流吸入部2吸入到主体壳1内的气流所含的尘埃中，大的尘埃在设置于回旋壁9的尘埃排出口10被分离，回收到尘埃回收箱7。尘埃回收箱7设置于各个回旋单元8的主体壳1的背面侧，尘埃排出口10在主体壳1的背面侧开口。Therefore, when the fan 4 is driven, the airflow entering the dust cyclone separation part 5 from the airflow suction part 2 is swirled by the swirling unit 8, and the dust contained in the airflow sucked from the airflow suction part 2 into the main body case 1 by the swirl is , large dust is separated at the dust outlet 10 provided on the revolving wall 9, and is recovered to the dust recovery box 7. The dust recovery box 7 is provided on the back side of the main body case 1 of each swirling unit 8 , and the dust discharge port 10 is opened on the back side of the main body case 1 .
另外，在尘埃回收箱7内，如图3所示设置有循环风路11，从多个尘埃排出口10吹出的气流的吹出方向与循环风路11的循环方向相同，气流与粉尘一起从多个尘埃排出口10被吹出到循环风路11内。In addition, in the dust recovery box 7, as shown in Figure 3, a circulating air passage 11 is provided, and the blowing direction of the airflow blown out from a plurality of dust outlets 10 is the same as the circulation direction of the circulating air passage 11, and the airflow and dust flow from many The dust discharge port 10 is blown out into the circulating air path 11.
即，本实施方式的尘埃回旋分离部5为具有多个回旋单元8和与设置于各个回旋单元8的回旋壁9上的尘埃排出口10外连结的尘埃回收箱7的结构。根据该结构，能够利用多个回旋单元8将广泛的尘埃除尘到尘埃回收箱7，能够提高除尘效果。That is, the dust swirling separation unit 5 of the present embodiment has a structure including a plurality of swirling units 8 and a dust recovery box 7 connected to the dust discharge port 10 provided on the swirling wall 9 of each swirling unit 8 . According to this structure, a wide range of dust can be dedusted to the dust recovery box 7 by a plurality of swirl units 8, and the dust removal effect can be improved.
另外，在尘埃回收箱7内设置有循环风路11，气流与粉尘一起从多个尘埃排出口10向与循环风路11的循环方向相同的方向吹出。根据该结构，因从各尘埃排出口10与尘埃一起吹出的气流，在尘埃回收箱7内的循环风路11产生循环气流。In addition, a circulating air duct 11 is provided in the dust collection box 7 , and the airflow is blown out in the same direction as the circulation direction of the circulating air duct 11 from a plurality of dust discharge ports 10 together with dust. According to this structure, the circulation airflow is generated in the circulation air path 11 in the dust recovery box 7 by the airflow blown together with the dust from each dust discharge port 10 .
由此，能够抑制从各个回旋单元8的尘埃排出口10吹出的粉尘进入其他回旋单元8的尘埃排出口10，作为其结果，能够提高各个回旋单元8每个的除尘效果。Thereby, dust blown from the dust outlet 10 of each swirl unit 8 can be prevented from entering the dust outlet 10 of another swirl unit 8 , and as a result, the dust removal effect of each swirl unit 8 can be improved.
在此，对尘埃排出口10附近的气流的流动进行说明。如图5所示，回旋单元8包括：筒形状的回旋壁9；和以将回旋壁的一方形成盖的方式以螺旋形状形成壁，通过螺旋的落差构成气流吸入部2的螺旋壁9a。而且，从气流吸入部2流入的气流通过回旋壁9和螺旋壁9a边回旋边向回旋壁9的轴向行进。这时，气流从尘埃排出口10沿着回旋流的方向向斜下方向吹出。与尘埃排出口10连接的尘埃回收箱7在尘埃排出口10以外没有开口，而回旋流的一部分如上述说明，保持指向性地吹出。另外，在尘埃排出口10必然也会产生从尘埃回收箱7向回旋单元8去的流动。Here, the flow of the airflow in the vicinity of the dust discharge port 10 will be described. As shown in FIG. 5 , the swirling unit 8 includes: a cylindrical swirling wall 9 ; and a spiral wall 9 a formed in a spiral shape such that one of the swirling walls is covered, and the airflow suction portion 2 is formed by the height difference of the spiral. Then, the airflow flowing in from the airflow suction part 2 advances in the axial direction of the swirl wall 9 while swirling through the swirl wall 9 and the spiral wall 9 a. At this time, the airflow is blown obliquely downward from the dust discharge port 10 along the direction of the swirling flow. The dust recovery box 7 connected to the dust discharge port 10 has no opening other than the dust discharge port 10, and a part of the swirling flow is blown out while maintaining the directionality as described above. In addition, a flow from the dust recovery box 7 to the swirling unit 8 inevitably occurs at the dust discharge port 10 .
另外，如图3所示，循环风路11由在上下方向配置且连通尘埃排出口10的第1风路部12和同样在上下方向配置的第2风路部13构成。而且，第1风路部12和第2风路部13，上端彼此连通，并且下端彼此连通。气流与粉尘一起从各个回旋单元8的尘埃排出口10向斜下方吹出到第1风路部12。具体而言，在尘埃回收箱7内设置有在上下方向延伸的平板形状的分隔板14，分隔出第1风路部12和第2风路部13。第1风路部12和第2风路部13相对于分隔板14位于主体壳1的左右方向，第1风路部12位于比第2风路部13靠主体壳1的内方侧。在分隔板14的上端具有将第1风路部12和第2风路部13的上端彼此连通的上端连通部15，在分隔板14的下端设置有将第1风路部12和第2风路部13的下端彼此连通的下端连通部16。In addition, as shown in FIG. 3 , the circulating air passage 11 is composed of a first air passage portion 12 arranged vertically and communicating with the dust outlet 10 , and a second air passage portion 13 also arranged vertically. Moreover, the upper ends of the first air passage part 12 and the second air passage part 13 communicate with each other, and the lower ends communicate with each other. The airflow is blown obliquely downward from the dust outlet 10 of each swirl unit 8 to the first air passage portion 12 together with the dust. Specifically, a flat plate-shaped partition plate 14 extending in the vertical direction is provided in the dust collection box 7 to partition the first air passage portion 12 and the second air passage portion 13 . The first air passage portion 12 and the second air passage portion 13 are located in the left-right direction of the main body case 1 with respect to the partition plate 14 , and the first air passage portion 12 is located on the inner side of the main body case 1 than the second air passage portion 13 . The upper end of the partition plate 14 has an upper end communicating portion 15 that connects the upper ends of the first air passage portion 12 and the second air passage portion 13. 2. A lower end communicating portion 16 in which the lower ends of the air passage portion 13 communicate with each other.
根据以上的结构，气流与粉尘一起从多个尘埃排出口10向斜下方吹出到第1风路部12。通过向斜下方吹出到该第1风路部12的气流，第1风路部12内成为向下方流动的气流。该气流经由下端连通部16向第2风路部13流动，在第2风路部13成为向上方流动的气流。该气流再次经由上端连通部15成为向第1风路部12流动的气流。由此，通过从设置于各个回旋单元8的回旋壁9的尘埃排出口10与尘埃一起吹出的气流，在尘埃回收箱7内的循环风路11中产生循环气流。另外，一部分气流再次返回到回旋单元8。According to the above configuration, the airflow is blown out obliquely downward from the plurality of dust discharge ports 10 to the first air passage portion 12 together with the dust. With the airflow blown obliquely downward to the first air passage portion 12 , the inside of the first air passage portion 12 becomes an airflow flowing downward. This air flow flows toward the second air passage portion 13 via the lower end communication portion 16 , and becomes an air flow flowing upward in the second air passage portion 13 . This airflow passes through the upper end communicating portion 15 again and becomes an airflow flowing toward the first air passage portion 12 . Thus, a circulating air flow is generated in the circulating air duct 11 in the dust recovery box 7 by the air flow blown out together with the dust from the dust discharge port 10 provided on the swirling wall 9 of each swirling unit 8 . In addition, part of the air flow is returned to the swirling unit 8 again.
这样，向斜下方吹出到第1风路部12的气流成为在第1风路部12内向下方流动的气流，在下端连通部16，流动的方向从下方向变成上方向。即，如图3中记载的箭头，气流成为U形回转的流动，气流中所含的尘埃受到向下方向的离心力。由此，气流中所含的尘埃的一部分未向第2风路部13流动，而是同时作用离心力和重力，由此易堆积在尘埃回收箱7内的底部或角部等。作为结果，能够抑制从各个回旋单元8的尘埃排出口10吹出的粉尘进入其他回旋单元8的尘埃排出口10的情况。Thus, the airflow blown obliquely downward to the first air passage portion 12 becomes an airflow flowing downward in the first air passage portion 12 , and the direction of flow changes from downward to upward in the lower end communicating portion 16 . That is, as shown by the arrows in FIG. 3 , the airflow becomes a U-turn flow, and the dust contained in the airflow receives a downward centrifugal force. As a result, part of the dust contained in the airflow does not flow toward the second air passage portion 13 , but both centrifugal force and gravity act on it, thereby easily accumulating on the bottom or corners of the dust collection box 7 . As a result, it is possible to suppress the dust blown out from the dust discharge port 10 of each swirl unit 8 from entering the dust discharge port 10 of another swirl unit 8 .
另外，第2风路部13的水平截面积比第1风路部12的水平截面积大。即，在第2风路部13向上方流动的气流的速度比在第1风路部12向下方流动的气流的速度小。In addition, the horizontal cross-sectional area of the second air passage portion 13 is larger than the horizontal cross-sectional area of the first air passage portion 12 . That is, the velocity of the airflow flowing upward through the second air passage portion 13 is lower than the velocity of the airflow flowing downward through the first air passage portion 12 .
这样，在第2风路部13向上方流动的气流的速度比在第1风路部12向下方流动的气流的速度小，所以在第1风路部12向下方流动的气流中所含的尘埃的一部分难以在第2风路部13向上方流动，更容易堆积在尘埃回收箱7内的角部等。作为结果，能够抑制从各个回旋单元8的尘埃排出口10吹出的气流的粉尘进入其他回旋单元8的尘埃排出口10的情况。In this way, the velocity of the airflow flowing upward in the second air passage part 13 is smaller than the velocity of the airflow flowing downward in the first air passage part 12, so the air contained in the airflow flowing downward in the first air passage part 12 Part of the dust is less likely to flow upward through the second air passage portion 13 and is more likely to be deposited in corners and the like in the dust collection box 7 . As a result, it is possible to suppress the dust in the airflow blown out from the dust discharge port 10 of each swirl unit 8 from entering the dust discharge port 10 of another swirl unit 8 .
如上所述，粉尘因下端连通部16的U形回转的气流而被分离，而且，第2风路部13的截面积比第1风路部12大，所以粉尘难以上升，因此上端连通部15中的粉尘浓度变低。根据这些结构，提高了将从各个回旋单元8的尘埃排出口10吹出的气流的粉尘留在尘埃回收箱7内的效果，作为结果，能够提高尘埃回旋分离部5的除尘效果。As mentioned above, the dust is separated due to the U-shaped air flow of the lower end communicating portion 16, and the cross-sectional area of the second air passage portion 13 is larger than that of the first air passage portion 12, so the dust is difficult to rise, so the upper end communicating portion 15 The dust concentration in the air becomes lower. According to these configurations, the effect of keeping the dust in the airflow blown out from the dust outlet 10 of each swirl unit 8 in the dust collection box 7 is improved, and as a result, the dust removal effect of the dust swirl separation unit 5 can be improved.
产业上的利用可能性Industrial Utilization Possibility
这样，除尘装置有望作为在家庭或办公室等有效利用的除尘装置来应用。Thus, the dust remover is expected to be applied as a dust remover that is effectively used in homes, offices, and the like.
