Description

清掃機 Sweeper

本發明係關於一種清掃機，更具體地，係關於一種能夠防止異物透過形成在本體與旋轉板之間的間隙進入的清掃機。 The present invention relates to a cleaning machine, and more particularly, to a cleaning machine capable of preventing foreign matter from entering through a gap formed between a body and a rotating plate.

清掃機是一種清掃裝置，用於從地板吸取如灰塵等異物或擦拭地板上的異物。近來，已經開發了一種能夠拖地的清掃機。另外，清掃機器人是一種自動驅動的同時自動清掃的裝置。 A sweeper is a sweeping device for sucking foreign matter such as dust from the floor or wiping foreign matter on the floor. Recently, a sweeper capable of mopping floors has been developed. In addition, the cleaning robot is a device that is automatically driven and cleaned automatically.

圖1是例示顯示出習知之清掃機器人的剖面圖。 FIG. 1 is a sectional view illustrating a conventional cleaning robot.

參見圖1，習知之清掃機器人1配置成使得一對旋轉板3設置在左和右方向上，並可旋轉地耦接到本體2，以及拖把(圖未示出)附接到旋轉板3以擦拭地板。此處，旋轉板3緊固至軸4，以接收軸4的旋轉力，並且軸4是由軸承5支撐以在本體1中旋轉。軸4透過驅動組件(圖未示出)旋轉。 Referring to FIG. 1, a known cleaning robot 1 is configured such that a pair of rotating plates 3 are arranged in left and right directions, and are rotatably coupled to a body 2, and a mop (not shown) is attached to the rotating plates 3 for Wipe the floor. Here, the rotating plate 3 is fastened to the shaft 4 to receive the rotational force of the shaft 4 , and the shaft 4 is supported by the bearing 5 to rotate in the body 1 . The shaft 4 is rotated through a driving assembly (not shown).

根據相關技術的清掃機器人1具有在旋轉板3與本體2之間形成的間隙。亦即，由於旋轉板3配置成要進行旋轉，旋轉板3設置為與本體2的下表面間隔開而不接觸到該下表面，使得間隙形成在旋轉板3與本體2之間。 The cleaning robot 1 according to the related art has a gap formed between the rotating plate 3 and the body 2 . That is, since the rotating plate 3 is configured to rotate, the rotating plate 3 is arranged to be spaced apart from the lower surface of the body 2 without contacting the lower surface so that a gap is formed between the rotating plate 3 and the body 2 .

透過此種結構，當間隙形成在旋轉板3與本體2之間時，在清掃機器人1執行清掃的同時，周圍的異物諸如液體、毛髮、細顆粒等便容易進入旋轉板3與本體2之間的間隙中，如圖1中箭頭的方向所示。 Through this structure, when the gap is formed between the rotating plate 3 and the main body 2, while the cleaning robot 1 is performing cleaning, surrounding foreign objects such as liquid, hair, fine particles, etc. will easily enter between the rotating plate 3 and the main body 2 In the gap, as shown in the direction of the arrow in Figure 1.

另外，韓國專利申請公開第10-2008-0065477號(以下稱為“專利文獻1”)揭露了一種兼具吸塵清掃與蒸汽清掃雙重目的之吸塵清掃機。在專利文獻1中，將拖把附接到本體的拖把附接板也配置成要進行旋轉。在專利文獻1中，由於拖把附接板上側的一部分暴露於外側，因此諸如液體、毛髮、細顆粒等的異物容易透過暴露於拖把附接板的上側，進入拖把附接板與本體之間。 In addition, Korean Patent Application Publication No. 10-2008-0065477 (hereinafter referred to as "Patent Document 1") discloses a vacuum cleaning machine with dual purposes of vacuum cleaning and steam cleaning. In Patent Document 1, the mop attachment plate that attaches the mop to the body is also configured to be rotated. In Patent Document 1, since a part of the upper side of the mop attachment plate is exposed to the outside, foreign matter such as liquid, hair, fine particles, etc. easily enters between the mop attachment plate and the body through the exposed upper side of the mop attachment plate.

如上所述，當諸如毛髮或細顆粒的異物進入本體與旋轉板之間時，毛髮會纏繞在旋轉板的旋轉軸上，並且作用於對馬達的旋轉阻力，而當細顆粒卡在旋轉板與本體之間時，會作用於對旋轉板的旋轉阻力。 As described above, when foreign matter such as hair or fine particles enters between the body and the rotating plate, the hair is entangled on the rotating shaft of the rotating plate and acts as a rotational resistance to the motor, while when the fine particles get stuck between the rotating plate and the When it is between the main body, it will act as a rotation resistance to the rotating plate.

因此，存在此些問題，亦即，此類旋轉阻力可能造成馬達的過載而引起馬達的故障，被引入的液體可能透過軸進入本體的內部，而引起電子裝置的故障，且卡在本體與旋轉板之間的細顆粒可能會損壞本體和旋轉板。 Therefore, there are such problems that such rotation resistance may cause overload of the motor to cause malfunction of the motor, and the introduced liquid may enter the inside of the body through the shaft to cause malfunction of the electronic device, and get stuck between the body and the rotation. Fine particles between the plates can damage the body and rotating plates.

藉由此種結構，當儲存在水箱230中的液體透過供水管240從旋轉板300的上側噴出時，清掃機10可以透過形成在旋轉板300的通孔340而將液體供應給拖把20。如此一來，可以週期性地供應液體，以使拖把20不致乾燥，從而提高清掃的性能。 With this structure, when the liquid stored in the water tank 230 is sprayed from the upper side of the rotating plate 300 through the water supply pipe 240 , the cleaning machine 10 can supply the liquid to the mop 20 through the through hole 340 formed in the rotating plate 300 . In this way, liquid can be supplied periodically so that the mop 20 does not dry out, thereby improving cleaning performance.

根據本發明該例示性實施例的清掃機提供一種能夠防止異物進入形成在本體與旋轉板之間的間隙的結構。 The cleaning machine according to this exemplary embodiment of the present invention provides a structure capable of preventing foreign matter from entering a gap formed between a body and a rotating plate.

以下將參見圖5至圖13詳細描述此種結構。 Such a structure will be described in detail below with reference to FIGS. 5 to 13 .

圖9是示意性地顯示根據本發明第一例示性實施例之清掃機的阻擋部沿著圖5的I-I'區域所切割的剖面圖和局部放大圖；以及圖10是顯示根據本發明該第一例示性實施例之清掃機的阻擋部的另一例示性實施例的剖面圖。 Fig. 9 is a sectional view and a partial enlarged view schematically showing that the blocking portion of the cleaning machine according to the first exemplary embodiment of the present invention is cut along the II' region of Fig. 5; A cross-sectional view of another exemplary embodiment of the blocking portion of the cleaning machine of the first exemplary embodiment.

另外，由於根據本發明該例示性實施例之清掃機10的本體100具有如下結構：本體100由下本體110和上本體120組成(參見圖3)，並且下本體110設置有旋轉板300和阻擋部，因此以下將基於下本體110進行描述。 In addition, since the body 100 of the cleaning machine 10 according to this exemplary embodiment of the present invention has the following structure: the body 100 is composed of a lower body 110 and an upper body 120 (see FIG. 3 ), and the lower body 110 is provided with a rotating plate 300 and a blocking part, so the following will be described based on the lower body 110 .

參見圖5至圖9，根據本發明該例示性實施例的清掃機10包括阻擋部，設置在下本體110和旋轉板300的至少任一個中，以使下本體110與旋轉板300之間的距離最小化，該阻擋部防止異物進入下本體110與旋轉板300之間。亦即，該阻擋部設置在下本體110及/或旋轉板300中，以作用為在形成於下本體110與旋轉板300之間的間隙中的檔板，從而防止異物進入下本體110與旋轉板300之間。 Referring to FIGS. 5 to 9 , the cleaning machine 10 according to this exemplary embodiment of the present invention includes a blocking portion provided in at least any one of the lower body 110 and the rotating plate 300 so that the distance between the lower body 110 and the rotating plate 300 Minimized, the blocking portion prevents foreign matter from entering between the lower body 110 and the rotating plate 300 . That is, the blocking portion is provided in the lower body 110 and/or the rotating plate 300 to function as a baffle in a gap formed between the lower body 110 and the rotating plate 300, thereby preventing foreign matter from entering the lower body 110 and the rotating plate. Between 300.

根據本發明第一例示性實施例的阻擋部可以包含外凸條610以及內凸條620。 The blocking part according to the first exemplary embodiment of the present invention may include an outer convex strip 610 and an inner convex strip 620 .

外凸條610可以配置為環形從下本體110突出，以設置在旋轉板300的徑向外側，以便圍繞旋轉板300。亦即，外凸條610可以沿著徑向設置在旋轉板300的外側，以防止異物沿著旋轉板300的徑向進入。 The outer protrusion 610 may be configured to protrude from the lower body 110 in a ring shape to be disposed radially outside the rotation plate 300 so as to surround the rotation plate 300 . That is, the outer convex strip 610 may be arranged radially outside the rotating plate 300 to prevent foreign matter from entering along the radial direction of the rotating plate 300 .

外凸條610可以設置為與旋轉板300的一端間隔開，以便不接觸旋轉板300。亦即，在旋轉板300旋轉的情況下，當旋轉板300的外端與外凸條610接觸時，外凸條610產生接觸阻力，而造成旋轉板300無法產生期望旋轉力的問題。另外，當馬達上有負擔時，能量效率可能降低且馬達可能發生故障。因此，外凸條610設置以圍繞旋轉板300的外端，但具有一預定間隙，使旋轉板300的旋轉不受到限制。 The outer convex bar 610 may be disposed spaced apart from one end of the rotating plate 300 so as not to contact the rotating plate 300 . That is, when the rotating plate 300 rotates, when the outer end of the rotating plate 300 contacts the outer convex strip 610 , the outer convex strip 610 produces contact resistance, which causes the problem that the rotating plate 300 cannot generate a desired rotational force. In addition, energy efficiency may decrease and the motor may fail when a load is placed on the motor. Therefore, the outer convex strip 610 is disposed to surround the outer end of the rotating plate 300 with a predetermined gap so that the rotation of the rotating plate 300 is not restricted.

外凸條610可以配置為突起，設置以形成區域A，其中該突起與旋轉板300在旋轉板300的厚度方向上以一預定面積彼此重疊。 The outer convex strip 610 may be configured as a protrusion configured to form an area A, wherein the protrusion and the rotating plate 300 overlap each other by a predetermined area in a thickness direction of the rotating plate 300 .

在此，當外凸條610的突起配置以在旋轉板300的厚度方向上突出，而完整地圍繞旋轉板300的外側時，在突起與附接到旋轉板300的拖把之間產生接觸阻力，而導致該接觸阻力作為抵抗旋轉板300旋轉力的問題。 Here, when the protrusions of the outer convex strip 610 are configured to protrude in the thickness direction of the rotating plate 300 while completely surrounding the outer side of the rotating plate 300 , contact resistance is generated between the protrusions and the mop attached to the rotating plate 300 , Instead, the contact resistance is caused as a problem against the rotational force of the rotating plate 300 .

另外，當外凸條610的突起突出，使得該突起和旋轉板300在旋轉板300的厚度方向上沒有形成彼此重疊的區域時，在外凸條610與旋轉板300之間沿著旋轉板300的徑向會產生間隙，從而造成異物透過該間隙進入的問題。 In addition, when the protrusion of the outer convex strip 610 is protruded so that the protrusion and the rotating plate 300 do not form a region overlapping with each other in the thickness direction of the rotating plate 300 , between the outer convex strip 610 and the rotating plate 300 along the direction of the rotating plate 300 A gap is created in the radial direction, causing a problem of foreign matter entering through the gap.

因此，外凸條610形成為突起，其中形成了該突起與旋轉板300在旋轉板300的厚度方向上彼此重疊的區域A，因此防止產生與拖把之間的接觸阻力，並且在旋轉板300的徑向上不會產生間隙，從而防止了異物的進入。 Therefore, the outer convex strip 610 is formed as a protrusion in which an area A where the protrusion and the rotating plate 300 overlap each other in the thickness direction of the rotating plate 300 is formed, thus preventing the generation of contact resistance with the mop, and in the rotating plate 300. There is no gap in the radial direction, preventing the entry of foreign matter.

內凸條620可以配置為環形從下本體110突出，以便面向位於外凸條610與旋轉板300的旋轉軸之間的旋轉板300。 The inner protrusion 620 may be configured to protrude from the lower body 110 in a ring shape so as to face the rotation plate 300 between the outer protrusion 610 and the rotation shaft of the rotation plate 300 .

內凸條620形成在旋轉板300的旋轉軸附近，即使異物進入到下本體110與旋轉板300之間，也能夠防止異物進入旋轉板300的旋轉軸，即軸400和軸承500側。 The inner convex line 620 is formed near the rotating shaft of the rotating plate 300 , even if foreign matter enters between the lower body 110 and the rotating plate 300 , it can prevent foreign matter from entering the rotating shaft of the rotating plate 300 , that is, the side of the shaft 400 and the bearing 500 .

在此，內凸條620突出使得其突出端面向旋轉板300的上側，但形成為不與旋轉板300的上側接觸。亦即，當內凸條620和旋轉板300的上側接觸時，可能產生阻力抵抗旋轉板300旋轉力的問題。 Here, the inner convex bar 620 protrudes such that its protruding end faces the upper side of the rotary plate 300 , but is formed not to be in contact with the upper side of the rotary plate 300 . That is, when the inner convex line 620 is in contact with the upper side of the rotating plate 300 , there may be a problem of resistance against the rotating force of the rotating plate 300 .

另外，內凸條620引導被引入的異物通過形成在旋轉板300的通孔340排出。 In addition, the inner protrusion 620 guides the introduced foreign matter to be discharged through the through hole 340 formed in the rotating plate 300 .

為此，內凸條620可以配置以從下本體110朝旋轉板300的中心板310突出，如圖9所示。可替代地，內凸條620可以配置以從下本體110朝旋轉板300的通孔340突出，如圖10所示。 For this, the inner protrusion 620 may be configured to protrude from the lower body 110 toward the center plate 310 of the rotating plate 300, as shown in FIG. 9 . Alternatively, the inner protrusion 620 may be configured to protrude from the lower body 110 toward the through hole 340 of the rotating plate 300 , as shown in FIG. 10 .

主要地，外凸條610防止異物進入下本體110與旋轉板300之間，但是諸如液體、灰塵、毛髮等的細微物質仍可能進入形成在旋轉板300與外凸條610之間的間隙中。以此方式進入的異物可能沿著下本體110與旋轉板300之間的間隙而被引入旋轉板300的旋轉軸中，即軸400和軸承500中。以此種方式進入的異物被引入軸承500中，並可能對旋轉造成阻力，或可能損壞軸承500。 Mainly, the outer convex bar 610 prevents foreign matter from entering between the lower body 110 and the rotating plate 300 , but fine substances such as liquid, dust, hair, etc. may still enter the gap formed between the rotating plate 300 and the outer convex bar 610 . The foreign matter entered in this way may be introduced into the rotation shaft of the rotation plate 300 , ie, the shaft 400 and the bearing 500 along the gap between the lower body 110 and the rotation plate 300 . The foreign matter entered in this way is introduced into the bearing 500 and may cause resistance to rotation, or may damage the bearing 500 .

因此，由於內凸條620配置以從下本體110朝中心板310或旋轉板300的通孔340突出，即使當異物透過外凸條610進入下本體110與旋轉板300之間時，內凸條620阻擋移動路徑以防止被引入的異物朝軸承500移動，並引導被阻擋的異物落入到旋轉板300的通孔340中，從而作用以將被引入的異物排放到外部。 Therefore, since the inner convex strip 620 is configured to protrude from the lower body 110 toward the center plate 310 or the through hole 340 of the rotating plate 300 , even when foreign matter enters between the lower body 110 and the rotating plate 300 through the outer convex strip 610, the inner convex strip 620 blocks the moving path to prevent the introduced foreign matter from moving toward the bearing 500 , and guides the blocked foreign matter to fall into the through hole 340 of the rotary plate 300 , thereby acting to discharge the introduced foreign matter to the outside.

根據本發明第一例示性實施例的阻擋部可以進一步包含中央凸條630，以環形從下本體110突出，以便面向外凸條610與內凸條620之間的旋轉板300。 The blocking part according to the first exemplary embodiment of the present invention may further include a central protrusion 630 protruding from the lower body 110 in a ring shape so as to face the rotating plate 300 between the outer protrusion 610 and the inner protrusion 620 .

中央凸條630形成在外凸條610與內凸條620之間的中央區域附近，即使異物進入下本體110與旋轉板300之間，也可以減緩其進入旋轉板300的旋轉軸的速度，即軸400和軸承500側。 The central convex strip 630 is formed near the central area between the outer convex strip 610 and the inner convex strip 620, even if foreign matter enters between the lower body 110 and the rotating plate 300, it can slow down the speed of entering the rotating shaft of the rotating plate 300, that is, the shaft 400 and bearing 500 sides.

在圖式中，僅示出一個中央凸條630，但可以在下本體110中外凸條610與內凸條620之間形成複數個中央凸條630。另外，該複數個中央凸條可以彼此具有不同的高度。 In the drawings, only one central convex strip 630 is shown, but a plurality of central convex strips 630 may be formed between the outer convex strip 610 and the inner convex strip 620 in the lower body 110 . In addition, the plurality of central ribs may have different heights from each other.

另外，中央凸條630可以形成為使得中央凸條630的突起小於內凸條620的突起。亦即，中央凸條630形成為不阻擋被引入異物沿著旋轉板300旋轉軸的方向移動，而是作用為阻力以減緩被引入異物的移動速度。 In addition, the central convex line 630 may be formed such that a protrusion of the central convex line 630 is smaller than that of the inner convex line 620 . That is, the central rib 630 is formed not to block the movement of the introduced foreign matter in the direction of the rotation axis of the rotary plate 300, but to act as a resistance to slow down the moving speed of the introduced foreign matter.

當中央凸條630形成以具有與內凸條620之突起的高度相似的高度，並阻擋異物沿著旋轉板300旋轉軸的方向移動時，異物會儲存在中央凸條630與外凸條610之間而沒有被排放到外部，因此當儲存一定量以上的異物時，會對旋轉板300的旋轉力產生阻力的問題。 When the central protrusion 630 is formed to have a height similar to that of the protrusion of the inner protrusion 620 and prevent foreign matter from moving along the direction of the rotation axis of the rotating plate 300, the foreign matter will be stored between the central protrusion 630 and the outer protrusion 610. Therefore, when a certain amount or more of foreign matter is stored, there is a problem of resistance to the rotational force of the rotating plate 300 .

因此，中央凸條630可以形成為突起，其減慢被引入的異物的移動速度，但是仍允許被引入的異物移動，從而通過旋轉板300的通孔340排放到外部。 Accordingly, the central rib 630 may be formed as a protrusion that slows down the moving speed of the introduced foreign matter but still allows the introduced foreign matter to move so as to be discharged to the outside through the through hole 340 of the rotating plate 300 .

藉由此種結構，根據本發明第一例示性實施例的阻擋部主要透過旋轉板300最外側處的外凸條610來防止異物進入，且即使當有被引入的異物，同時透過中央凸條630減緩被引入異物的移動速度時，阻擋部可以使內凸條620將被引入的異物引導到旋轉板300的通孔340，從而將被引入的異物排放到外部。因此，可以防止異物藉由進入軸400或軸承500側而成為旋轉或損壞組件的阻力。 With such a structure, the blocking part according to the first exemplary embodiment of the present invention mainly prevents foreign matter from entering through the outer convex strip 610 at the outermost side of the rotating plate 300, and simultaneously passes through the central convex strip even when foreign matter is introduced. When 630 slows down the moving speed of the introduced foreign matter, the blocking portion can enable the inner convex strip 620 to guide the introduced foreign matter to the through hole 340 of the rotating plate 300, thereby discharging the introduced foreign matter to the outside. Therefore, it is possible to prevent foreign matter from being a resistance to rotation or damaging components by entering the shaft 400 or the bearing 500 side.

圖11至13是示意性地顯示根據本發明例示性實施例的清掃機的第二例示性實施例的阻擋部的剖面圖。圖11至圖13是顯示基於與圖9的剖面圖所示之放大部分相同的部分。 11 to 13 are cross-sectional views schematically showing a blocking portion of a second exemplary embodiment of a sweeper according to an exemplary embodiment of the present invention. 11 to 13 show the same part based on the enlarged part shown in the sectional view of FIG. 9 .

參見圖11至圖13，根據本發明第二例示性實施例的阻擋部可以包含中央凸條630以及輔助凸條640。 Referring to FIGS. 11 to 13 , the blocking part according to the second exemplary embodiment of the present invention may include a central convex line 630 and an auxiliary convex line 640 .

中央凸條630可以配置為環形從下本體110突出，以便面向旋轉板300。此中央凸條630可以形成在下本體110上，以便從旋轉板300的外板320的上方面向外板320。 The central protrusion 630 may be configured to protrude from the lower body 110 in a ring shape so as to face the rotating plate 300 . This central protrusion 630 may be formed on the lower body 110 so as to face the outer panel 320 from above the outer panel 320 of the rotating panel 300 .

在此，中央凸條630突出使得其突出端面向旋轉板300的上側，但形成為不與旋轉板300的上側接觸。亦即，當中央凸條630與旋轉板300的上側接觸時，可能產生阻力抵抗旋轉板300旋轉力的問題。 Here, the central rib 630 protrudes such that its protruding end faces the upper side of the rotary plate 300 , but is formed not to be in contact with the upper side of the rotary plate 300 . That is, when the central rib 630 is in contact with the upper side of the rotating plate 300 , there may be a problem of resistance against the rotating force of the rotating plate 300 .

輔助凸條640可以配置為環形從旋轉板300突出，以面向下本體110。此輔助凸條640可以形成在外板320上，以便從旋轉板300的外板320面向下板320。 The auxiliary protrusion 640 may be configured to protrude from the rotating plate 300 in a ring shape to face the lower body 110 . This auxiliary protrusion 640 may be formed on the outer panel 320 so as to face the lower panel 320 from the outer panel 320 of the rotary panel 300 .

在此，輔助凸條640突出使得其突出端面向下本體110的下側，但形成為不與下本體110的下側接觸。亦即，當輔助凸條640與下本體110的下側接觸時，可能產生阻力作為抵抗旋轉板300旋轉力的問題。 Here, the auxiliary protrusion 640 protrudes such that its protruding end faces the lower side of the lower body 110 , but is formed not to contact the lower side of the lower body 110 . That is, when the auxiliary protrusion 640 is in contact with the lower side of the lower body 110 , resistance may be generated as a problem against the rotational force of the rotating plate 300 .

另外，輔助凸條640可以配置為與中央凸條630的內側相鄰設置，同時維持不與中央凸條630接觸的最小距離。 In addition, the auxiliary convex line 640 may be configured to be disposed adjacent to the inner side of the central convex line 630 while maintaining a minimum distance not to be in contact with the central convex line 630 .

亦即，當旋轉板300旋轉時，在輔助凸條640與中央凸條630接觸的情況下，中央凸條630產生接觸阻力，並可能造成旋轉板300無法產生期望的旋轉力的問題。 That is, when the rotating plate 300 rotates, when the auxiliary rib 640 is in contact with the central rib 630 , the central rib 630 generates contact resistance, which may cause a problem that the rotating plate 300 cannot generate a desired rotational force.

另外，當輔助凸條640與中央凸條630之間的距離較大時，由於阻擋的效果降低，因此輔助凸條640與中央凸條630之間的間隙為彼此不接觸的最小距離，以防止異物進入。 In addition, when the distance between the auxiliary ridge 640 and the central ridge 630 is large, the blocking effect is reduced, so the gap between the auxiliary ridge 640 and the central ridge 630 is the minimum distance that does not touch each other, so as to prevent Foreign matter has entered.

亦即，如圖11所示，當異物沿著旋轉板300的徑向進入時，即使當小顆粒的細微異物進入旋轉板300與中央凸條630之間的間隙時，輔助凸條640阻擋異物的移動，從而防止異物進入內部。 That is, as shown in FIG. 11 , when foreign matter enters along the radial direction of the rotating plate 300 , even when fine foreign matter of small particles enters the gap between the rotating plate 300 and the central protrusion 630 , the auxiliary rib 640 blocks the foreign matter movement, thereby preventing foreign matter from entering the interior.

藉由此種結構，根據本發明第二例示性實施例的阻擋部設置有中央凸條630以及輔助凸條640，以使下本體110與旋轉板300之間具有不規則形狀的間隙，藉此可以防止異物沿著旋轉板300的旋轉軸的方向進入。 With such a structure, the blocking part according to the second exemplary embodiment of the present invention is provided with the central protrusion 630 and the auxiliary protrusion 640 so that there is an irregular-shaped gap between the lower body 110 and the rotating plate 300, whereby Entry of foreign matter along the direction of the rotation axis of the rotation plate 300 can be prevented.

另外，參見圖12，根據本發明第二例示性實施例的阻擋部可以進一步包含內凸條620，以環形從下本體110突出，以便面向在中央凸條630與旋轉板的旋轉軸之間的旋轉板300。 In addition, referring to FIG. 12 , the blocking portion according to the second exemplary embodiment of the present invention may further include an inner convex strip 620 protruding from the lower body 110 in a ring shape so as to face the center between the central convex strip 630 and the rotation shaft of the rotating plate. Rotating plate 300 .

由於內凸條620形成在旋轉板300的旋轉軸附近，因此即使當異物進入下本體110與旋轉板300之間時，也可以防止異物進入旋轉板300的旋轉軸，即軸400和軸承500。 Since the inner protrusion 620 is formed near the rotation axis of the rotation plate 300 , even when foreign matter enters between the lower body 110 and the rotation plate 300 , foreign matter can be prevented from entering the rotation axis of the rotation plate 300 , that is, the shaft 400 and the bearing 500 .

在此，內凸條620突出使得其突出端面向旋轉板300的上側，但形成為不與旋轉板300的上側接觸。亦即，當內凸條620與旋轉板300的上側接觸時，可能產生阻力作為抵抗旋轉板300旋轉力的問題。 Here, the inner convex bar 620 protrudes such that its protruding end faces the upper side of the rotary plate 300 , but is formed not to be in contact with the upper side of the rotary plate 300 . That is, when the inner convex line 620 is in contact with the upper side of the rotary plate 300 , resistance may be generated as a problem against the rotational force of the rotary plate 300 .

另外，內凸條620引導被引入的異物通過旋轉板300的通孔340排出。 In addition, the inner convex strip 620 guides the introduced foreign matter to be discharged through the through hole 340 of the rotating plate 300 .

為此，內凸條620可以配置以從下本體110突出，以便面向旋轉板300的中心板310，如圖12所示。可替代地，內凸條620可以配置以從下本體110突出，以便面向旋轉板300的通孔340。 For this, the inner protrusion 620 may be configured to protrude from the lower body 110 so as to face the center plate 310 of the rotating plate 300, as shown in FIG. 12 . Alternatively, the inner protrusion 620 may be configured to protrude from the lower body 110 so as to face the through hole 340 of the rotation plate 300 .

主要地，中央凸條630和輔助凸條640防止異物進入下本體110與旋轉板300之間，但是諸如液體、灰塵等的細微物質可能進入形成在中央凸條630與輔助凸條640之間的間隙。以此方式進入的異物可能沿著下本體110與旋轉板300之間的間隙而被引入旋轉板300的旋轉軸中，即軸400和軸承500中。以此種方式進入的異物被引入軸承500中，並可能對旋轉造成阻力，或可能損壞軸承500。 Mainly, the central rib 630 and the auxiliary rib 640 prevent foreign matter from entering between the lower body 110 and the rotary plate 300, but fine substances such as liquid, dust, etc. gap. The foreign matter entered in this way may be introduced into the rotation shaft of the rotation plate 300 , ie, the shaft 400 and the bearing 500 along the gap between the lower body 110 and the rotation plate 300 . The foreign matter entered in this way is introduced into the bearing 500 and may cause resistance to rotation, or may damage the bearing 500 .

因此，由於內凸條620配置以從下本體110突出，以便面向中心板310或旋轉板300的通孔340，即使當異物透過中央凸條630和輔助凸條640進入下本體110與旋轉板300之間時，內凸條620阻擋移動路徑以防止被引入的異物朝軸承500移動，並引導被阻擋的異物落入到旋轉板300的通孔340中，從而作用以將被引入的異物排放到外部。 Therefore, since the inner rib 620 is configured to protrude from the lower body 110 so as to face the through hole 340 of the center plate 310 or the rotating plate 300 , even when foreign matter enters the lower body 110 and the rotating plate 300 through the central rib 630 and the auxiliary rib 640 During this period, the inner convex strip 620 blocks the movement path to prevent the introduced foreign matter from moving toward the bearing 500, and guides the blocked foreign matter to fall into the through hole 340 of the rotating plate 300, thereby acting to discharge the introduced foreign matter into the through hole 340 of the rotating plate 300 external.

參見圖13，根據本發明第二例示性實施例的阻擋部可以進一步包含外凸條610，以環形從下本體110突出，以設置在旋轉板300的徑向外側，以便圍繞旋轉板300。亦即，外凸條610可以設置在旋轉板300的徑向外側，主要防止異物沿著旋轉板300的徑向進入。 Referring to FIG. 13 , the blocking portion according to the second exemplary embodiment of the present invention may further include an outer protrusion 610 protruding from the lower body 110 in a ring shape to be disposed radially outside the rotating plate 300 so as to surround the rotating plate 300 . That is to say, the outer convex strip 610 may be arranged on the radially outer side of the rotating plate 300 , mainly preventing foreign matter from entering along the radial direction of the rotating plate 300 .

外凸條610可以設置為與旋轉板300的該端間隔開，而不接觸旋轉板300。亦即，當旋轉板300旋轉時，旋轉板300的外端與外凸條610接觸，外凸條610產生接觸阻力，從而造成旋轉板300無法產生期望旋轉力的問題。因此，外凸條610設置以圍繞旋轉板300的外端，但具有一預定間隙的形式，使旋轉板300的旋轉不受到限制。 The outer convex bar 610 may be disposed spaced apart from the end of the rotating plate 300 without contacting the rotating plate 300 . That is, when the rotating plate 300 rotates, the outer end of the rotating plate 300 is in contact with the outer convex strip 610 , and the outer convex strip 610 produces contact resistance, which causes the problem that the rotating plate 300 cannot generate a desired rotational force. Therefore, the outer convex strip 610 is disposed to surround the outer end of the rotating plate 300 but in the form of a predetermined gap so that the rotation of the rotating plate 300 is not restricted.

外凸條610可以配置為突起，設置以形成其中該突起與旋轉板300在旋轉板300的厚度方向上以一預定面積彼此重疊的區域。 The outer convex strip 610 may be configured as a protrusion disposed to form a region in which the protrusion and the rotation plate 300 overlap each other by a predetermined area in the thickness direction of the rotation plate 300 .

此處，當外凸條610的突起配置以在旋轉板300的厚度方向上突出，以便完整地圍繞旋轉板300的外側時，在該突起與附接到旋轉板300的拖把之間產生接觸阻力，從而導致該接觸阻力作為抵抗旋轉板300旋轉力的問題。 Here, when the protrusion of the outer convex strip 610 is configured to protrude in the thickness direction of the rotating plate 300 so as to completely surround the outer side of the rotating plate 300 , contact resistance is generated between the protrusion and the mop attached to the rotating plate 300 , thus causing the contact resistance as a problem against the rotational force of the rotating plate 300 .

另外，當外凸條610的突起突出使得沒有形成該突起與旋轉板300在旋轉板300的厚度方向上彼此重疊的區域時，間隙在外凸條610與旋轉板300之間沿著旋轉板300的徑向產生，從而造成異物透過該間隙進入的問題。 In addition, when the protrusion of the outer convex strip 610 protrudes so that no region where the protrusion and the rotating plate 300 overlap each other in the thickness direction of the rotating plate 300 is formed, the gap is between the outer convex strip 610 and the rotating plate 300 along the edge of the rotating plate 300 . Radial generation, thus causing the problem of foreign matter entering through this gap.

因此，外凸條610形成為突起，其中形成了該突起與旋轉板300在旋轉板300的厚度方向上彼此重疊的區域，因此防止產生與拖把之間的接觸阻力，並在旋轉板300的徑向上不會產生間隙，從而防止了異物的進入。 Therefore, the outer protruding strip 610 is formed as a protrusion in which a region where the protrusion and the rotating plate 300 overlap each other in the thickness direction of the rotating plate 300 is formed, thus preventing the generation of contact resistance with the mop, and in the radial direction of the rotating plate 300. There is no gap upward, preventing the entry of foreign matter.

藉由此種結構，根據本發明第二例示性實施例的阻擋部主要透過位於旋轉板300的最外側的外凸條610來防止異物進入，並且即使當殘留被引入的異物時，該阻擋部也可以透過中央凸條630和輔助凸條640再次地防止被引入異物的移動，並且穿過中央凸條630和輔助凸條640的異物可以藉由內凸條620引導至旋轉板300的通孔340以排放到外部。因此，可以防止異物進入軸400或軸承500側而成為抵抗旋轉或損壞組件的阻力。 With such a structure, the blocking portion according to the second exemplary embodiment of the present invention prevents entry of foreign matter mainly through the outer convex strip 610 located at the outermost side of the rotating plate 300, and even when the introduced foreign matter remains, the blocking portion The movement of the introduced foreign matter can also be prevented again through the central raised bar 630 and the auxiliary raised bar 640 , and the foreign matter passing through the central raised bar 630 and the auxiliary raised bar 640 can be guided to the through hole of the rotating plate 300 by the inner raised bar 620 340 to discharge to the outside. Therefore, it is possible to prevent foreign matter from entering the shaft 400 or the bearing 500 side to become a resistance against rotation or to damage components.

根據本發明例示性實施例的清掃機10可以進一步包括軸承蓋部800，以防止異物進入軸承500。 The cleaning machine 10 according to an exemplary embodiment of the present invention may further include a bearing cover part 800 to prevent foreign matter from entering the bearing 500 .

下本體110可以設置有軸承緊固件130，支撐可旋轉的軸400的軸承500固定至軸承緊固件130，軸400固定在旋轉板300以提供旋轉力。 The lower body 110 may be provided with a bearing fastener 130 to which a bearing 500 supporting a rotatable shaft 400 is fixed, and the shaft 400 is fixed to the rotation plate 300 to provide a rotation force.

此軸承蓋部800可以從軸承緊固件130朝旋轉板300突出，以使下本體110與旋轉板300之間的距離最小化，防止異物進入軸承500側。 This bearing cover part 800 may protrude from the bearing fastener 130 toward the rotating plate 300 to minimize the distance between the lower body 110 and the rotating plate 300 and prevent foreign matter from entering the bearing 500 side.

參見圖9，作為示例，軸承蓋部800可以包含支撐部810以及蓋部820。 Referring to FIG. 9 , as an example, the bearing cover part 800 may include a support part 810 and a cover part 820 .

支撐部810可以從軸承緊固件130延伸並朝旋轉板300突出。亦即，支撐部810可以配置以藉由延伸到形成在下本體110的軸承緊固件130，來朝旋轉板300突出。 The support part 810 may extend from the bearing fastener 130 and protrude toward the rotation plate 300 . That is, the support part 810 may be configured to protrude toward the rotation plate 300 by extending to the bearing fastener 130 formed on the lower body 110 .

另外，支撐部810類似於上述之內凸條620突出為突起，從而阻擋進入下本體110與旋轉板300之間的異物沿著徑向方向引入。 In addition, the support portion 810 is protruded as a protrusion similar to the above-mentioned inner rib 620 , so as to block foreign matter entering between the lower body 110 and the rotating plate 300 from being introduced in a radial direction.

蓋部820可以在旋轉板300的旋轉軸的方向上從支撐部810突出，並設置以覆蓋軸承500下側的至少一部分。亦即，蓋部820從支撐部810的端部向內突出，以便圍繞軸承500的下表面並覆蓋軸承500的下表面，從而阻擋異物進入軸承500的下表面。 The cover part 820 may protrude from the support part 810 in the direction of the rotation shaft of the rotation plate 300 and be provided to cover at least a part of the lower side of the bearing 500 . That is, the cover part 820 protrudes inwardly from the end of the support part 810 so as to surround and cover the lower surface of the bearing 500 , thereby blocking foreign matters from entering the lower surface of the bearing 500 .

藉由此結構，支撐部810覆蓋軸承500的側表面，並且蓋部820覆蓋軸承500的下表面，從而即使當在下本體110與旋轉板300之間被引入的異物可能未被旋轉板300的通孔340排出，但有一部分異物移動至軸承500時，軸承蓋部800的支撐部810和蓋部820就可以防止異物進入軸承500。 With this structure, the support portion 810 covers the side surface of the bearing 500, and the cover portion 820 covers the lower surface of the bearing 500, so that even when foreign matter introduced between the lower body 110 and the rotary plate 300 may not be passed through the rotary plate 300 The hole 340 is discharged, but when a part of the foreign matter moves to the bearing 500 , the support part 810 and the cover part 820 of the bearing cover part 800 can prevent the foreign matter from entering the bearing 500 .

因此，根據本例示性實施例的清掃機具有阻擋部和軸承蓋部，因此阻擋部主要阻擋異物進入本體與旋轉板之間，且即使當一部分異物朝軸承側移動時，軸承蓋部也會再次地阻擋異物，從而防止異物進入軸承和軸。 Therefore, the cleaning machine according to this exemplary embodiment has the stopper and the bearing cover, so the stopper mainly stops foreign matter from entering between the body and the rotating plate, and even when a part of the foreign matter moves toward the bearing side, the bearing cover will again Blocks foreign matter perfectly, thereby preventing foreign matter from entering the bearing and shaft.
