    Grill assembly of cyclone dust collector for vacuum cleaner {GRILLE ASSEMBLE FOR A CYCLONE-TYPE DUST COLLECTING APPARATUS FOR A VACUUM CLEANER}
    [13] BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cyclone dust collector for a vacuum cleaner, and more particularly to a grill assembly of a cyclone dust collector for a vacuum cleaner that separates dirt from air swirling in the cyclone dust collector.
    [14] Cyclone is a device that separates particles in a fluid by using centrifugal force, and has been widely used as a dust collector in an industrial field for a long time because of its simple structure and withstanding high temperature and high pressure.
    [15] A vacuum cleaner having such a cyclone dust collector is configured to first collect the dust sucked with the air through the suction port before entering the paper filter of the cleaner body. Therefore, since the amount of dirt collected by the paper filter can be reduced, the paper filter can be used for a long time, and the suction force and the overload of the motor caused by the paper filter being easily filled with the dirt can be prevented. Etc.
    [16] As a representative example of a vacuum cleaner having a cyclone dust collector as described above, there is a filed by the present applicant (application number: 10-1999-20704) registered on November 28, 2001 (registration number: 317117).
    [17] 1 is a cross-sectional view schematically showing the structure and operation of a vacuum cleaner having a cyclone dust collector disclosed in Korean Patent Application No. 1999-20704, which is briefly described as follows.
    [18] As shown in FIG. 1, a vacuum cleaner having a cyclone dust collector disclosed in Korean Patent Application No. 1999-20704 is provided with a cyclone dust collector 10 installed in extension tubes 1a and 1b of a cleaner.
    [19] The cyclone dust collector 10 collects dirt from the swirling air stream by centrifugal force by allowing the intake air to form the swirling air stream. Equipped.
    [20] The cyclone body 20 has a first connecting pipe 21 connected to the suction port side extension pipe 1a of the cleaner, a second connecting pipe 22 connected to the body extension pipe 1b of the cleaner, and the first An air inlet 23 in communication with the connection pipe 21, and an air outlet 24 in communication with the second connection pipe 22, and air containing dirt introduced through the air inlet 23. To form swirling airflow.
    [21] The waste container 30 is detachably coupled to the cyclone body 20 and collects the dirt separated from the air by the swirling air flow formed by the cyclone body 20.
    [22] In addition, the grill assembly 40 is installed at the air outlet 24 of the cyclone body 20 to prevent the dirt collected in the waste container 30 is introduced into the cleaner body. The grill assembly 40 has a grill support portion 41, a conical grill portion 42 and a cylindrical grill portion 43 is integrally formed, the air outlet in the conical grill portion 42 and the cylindrical grill portion 43 A plurality of fine through holes 43a communicating with the 24 are formed. In addition, at the end of the cylindrical grill portion 43 is a conical dirt backflow prevention plate 44 is formed.
    [23] In the cyclone dust collector for a vacuum cleaner configured as described above, dirt, such as dust, flows in a diagonal direction with respect to the cyclone body 20 through the first connecting pipe 21 together with the suction air by the suction force generated at the suction port of the cleaner. As a result, the air is lowered to the bottom of the waste container 30 while forming a swirling air flow. In this process, the dirt contained in the air by centrifugal force is separated from the air and collected in the waste container 30. Subsequently, the air starts an inverted upward movement at the bottom surface of the waste container 30 and rotates with a smaller radius of rotation, thereby raising the micro-pass hole 43a of the grill assembly 40, the air outlet 24 and It is discharged to the cleaner body side through the second connecting pipe (22). At this time, some of the dirt that rises with the air by the air flow rising in the waste container 30 is lowered as it does not exit the fine passage hole (43a) of the grill assembly 40 to the waste container 30 It is collected.
    [24] On the other hand, some dirt that could not be separated from the swirling air is discharged to the air outlet 24 together with the air through the micro-pass hole 43a of the grill assembly 40, the dirt discharged with the air in this way is a cleaner The filter is collected by the paper filter of the main body, and the purified air is discharged to the outside of the cleaner through a motor.
    [25] According to the vacuum cleaner having the cyclone dust collector configured as described above, since the dirt contained in the air sucked through the suction port of the cleaner is collected and filtered by the cyclone dust collector, the dust collected by the paper filter in the cleaner body. Can reduce the amount of
    [26] However, the cyclone dust collector for a conventional vacuum cleaner as described above, as shown in Figure 2, the stream line of the air flow in which the plurality of micro-pass holes 43a of the grill assembly 40 is pivoted in the cyclone dust collector ( Since it is formed to have an angle of about 90 ° with respect to B), as indicated by the dotted arrow in Fig. 2, dirt contained in the air of the swirling air flow easily toward the cleaner body through the fine passage hole (43a). Inflow. Furthermore, since the conventional cyclone dust collector for vacuum cleaners does not have a means for filtering the dirt smaller than the size of the micro-pass hole 43a, most of the fine dust passes through the micro-pass hole 43a together with the air. The amount of dirt collected by the paper filter provided in the cleaner body is increased, thereby shortening the use time of the paper filter.
    [27] In addition, the conventional cyclone dust collector for the vacuum cleaner, the grill assembly 40 without some dirt contained in the air is discharged with the air during the discharge process of the air through the fine passage hole 43a of the grill assembly (40) The phenomenon of blocking the micro-pass hole 43a while sticking to the micro-pass hole 43a has occurred. In this way, when the micro-pass hole 43a is blocked, the air is not easily discharged, and thus, the suction force is lowered and the overload of the motor is caused. Therefore, the air must be periodically removed. There is a problem that it is very difficult and cumbersome to remove the existing dirt causes inconvenience of using the cleaner.
    [28] The present invention has been made in view of the above problems, it is difficult to pass through the grill of the dirt contained in the air of the swirling air, and by means of filtering the fine dirt by passing through the grill to the dirt flowing into the cleaner main body side It is an object of the present invention to provide a grill assembly of a cyclone dust collector for a vacuum cleaner, which can reduce the amount and extend the use time of a paper filter.
    [29] It is another object of the present invention to provide a grill assembly of a cyclone dust collector for a vacuum cleaner, which contributes to the improvement of convenience of cleaner use because it is very easy to remove dirt present on the grill.

    [31] The grill body is supported by an air outlet of the cyclone body and is separated into a first body part having a through hole and a second body part in which a plurality of blades are arranged, and the second body part is interposed between the first means through the coupling means. Removably coupled to the body portion.

It is desirable to be determined within.
    [35] The fine dirt blocking member may be made of a porous material such as a sponge.
    [36] Best Mode for Carrying Out the Invention Preferred embodiments of the present invention will now be described based on the accompanying drawings.
    [37] Figure 3 is an exploded perspective view showing a grill assembly of a cyclone dust collector for a vacuum cleaner according to an embodiment of the present invention, Figure 4 is a grill assembly according to an embodiment of the present invention shown in Figure 3 is mounted to the body of the cyclone dust collector 5 is a partial cross-sectional view for explaining the flow of air around the grill assembly of the cyclone dust collector for a vacuum cleaner according to an embodiment of the present invention. For reference, in describing the embodiments of the present invention, other components constituting the cyclone dust collector except for the grill assembly will be referred to with the same reference numerals as before.
    [38] 3 to 5, the grill assembly 100 of the cyclone dust collector for a vacuum cleaner according to an embodiment of the present invention, the upper portion is in communication with the air outlet 24 formed in the cyclone body 20 A plurality of grill body 110, which is disposed at a predetermined interval on the outer peripheral surface of the grill body 110 to form a flow path 121 in communication with the air outlet 24 along the outer peripheral surface of the grill body 110, the open A blade 120 and a fine dirt blocking member 130 embedded in the grill body 110 so as to be located at the flow path forming portion of the grill body 110 to catch the fine dirt passing through the flow path.
    [39] As shown in FIG. 3, the grill body 110 is divided into a first body part 111 having a through hole 111a and a first body part 112 in which a plurality of blades 120 are disposed. do. The second body portion 112 is detachably coupled to the first body portion 111 by the coupling means 140. The coupling means 140 is a pair of coupling grooves 141 formed to face the inner circumferential surface of the through hole 111a of the first body portion 111 and the second body so as to correspond to the coupling groove 141. It is composed of a pair of coupling protrusions 142 formed on both sides of the upper end of the portion (112). The coupling groove 141 includes a position guide portion 141a having an open lower portion and a coupling portion 141b with a lower portion extending therefrom. Therefore, the second body part 112 is rotated after inserting the coupling protrusion 142 of the second body part 112 into the position guide part 141a of the coupling groove 141 of the first body part 111. When the coupling protrusion 142 is located in the coupling portion 141b of the coupling groove 141, the second body portion 112 is coupled to the first body portion 111. Of course, the separation can be easily separated in the reverse order. According to this, when the dirt is attached to the grill body 110, the second body portion 112 is separated from the first body portion 111, the dirt attached to each blade 120 of the second body portion 112 Can be easily removed. In FIG. 3, reference numeral 150 denotes a dirt backflow prevention plate.
    [40] The plurality of blades 120 are spaced apart from each other to allow air communication along the outer circumferential surface of the grill body 110, specifically, the second body part 112. As a result, as shown in FIG. 4, a flow path 121 is formed between the blades 120.
    [41] Here, as shown in FIG. 5, the blade 120 is disposed such that the angle θ formed between the center line and the stream line B of the swirling air flow is acute. Therefore, the angle which the flow path 121 makes with the stream line B of swirling airflow becomes an acute angle. This makes it difficult for dirt contained in the air to pass through the flow path of the grill.
    [42] That is, as indicated by the dotted arrow in Fig. 5, in order to enter the flow path 121 between the blades 120, the dirt contained in the air flow must be switched by more than 90 degrees, in other words, turning Since it is necessary to reverse the direction of rotation of the airflow, it is difficult for the dirt to pass through the flow passage 121 by that amount.
    [43] The smaller the angle θ, the narrower the gap between the blades 120 (ie, the narrower the width of the flow path), the greater the flow resistance of the air passing through the flow path 121 accordingly. Therefore, not only the noise becomes worse but the efficiency of the vacuum cleaner may be lowered due to the lowering of the suction force. For this reason, the interval between the angle θ and the blade 120 should be appropriately set in view of the above.
    [44] To this end, the angle θ and the spacing between the blades 120 are about 10 to 50% of the shadows of the adjacent blades 120 'when the blades 120 are projected onto a coaxial virtual cylindrical surface. It is preferable to determine within the overlapping range.
    [45] The fine dirt blocking member 130 is embedded in the second body part 112 of the grill body 110 to filter out the fine dirt that passes through the flow passage 121. The fine dirt blocking member 130 is formed of a porous material such as a sponge having excellent breathability, but is not necessarily limited thereto. For example, it may be formed of a cylindrical mesh having a mesh structure.
    [46] 4 is a cyclone dust collector to which the grill assembly 100 according to the present invention configured as described above is applied. The grill assembly 100 is installed downward therefrom by its first body portion 111 being supported by the air outlet 24 of the cyclone body 20. In addition, the fine dirt blocking member 130 is embedded in the second body 112 of the grill body 110.
    [47] When the vacuum cleaner is operated, a swirling air flow is formed inside the cyclone body 20. Various dirts contained in the swirling airflow are separated from the airflow by the winshim force, and the separated dirt is collected by the waste container 30.
    [48] In this step, that is, some dirt that is not collected and separated from the airflow in the dirt collection step by centrifugal force is moved toward the grill assembly 100 by the ascending airflow while turning along the center of the dirt container 30.
    [49] At this time, some of the dirt contained in the air flow is reflected by hitting the dirt backflow prevention plate 150, the direction of travel is converted back to the turning air flow. Thus, the dirt is caught up in the swirling air again.
    [50] Dirt that is not separated from the raised airflow by the dirt backflow prevention plate 150 is moved toward the flow path 121 of the grill assembly 100. Air is introduced into the grill assembly 100 through the flow path 121 due to the pressure difference between the grill assembly 100 and the outside.
    [51] On the other hand, as described above, the flow path 121 formed by the plurality of blades 120 is formed to form an acute angle with the stream line (B) of the swirling air flow, the dirt is relatively larger than the air, so the specific gravity is higher than the air Has great inertia
    [52] That is, in order to enter the flow path 121 between the blades 120, the dirt contained in the airflow must overcome the large inertia as described above, and reverse the traveling direction of the swirling airflow by 90 degrees or more. Therefore, it is difficult for the dirt to pass through the flow passage 121 by that amount. Therefore, the amount of dirt moved toward the cleaner body is reduced. In particular, in the present invention, since the fine dirt blocking member 130 for filtering the fine dirt is installed in the second body portion 112 of the grill body, the fine dirt smaller than the flow path 121 is connected to the flow path 121. Even though passing through, it is filtered by the fine dirt blocking member 130 and does not flow into the cleaner body. Therefore, the amount of dirt moved toward the cleaner body is further reduced. Therefore, the use time of the paper filter can be extended more.
    [53] Meanwhile, dirt is attached to each blade 120 of the grill body 110 when the cleaner is used, and the fine dirt blocking member 130 installed therein is also contaminated. In this case, the present invention can be easily washed by separating the second body portion 112 from the first body portion 111.
    [54] According to the present invention as described above, since the inflow of air through the flow path of the grill body is difficult, it is possible to reduce the amount of dirt that is moved toward the cleaner body, in particular, fine dirt smaller than the size of the flow path fine blocking member It is possible to further reduce the amount of dirt moved toward the cleaner body because it is filtered by, thereby extending the use time of the paper filter.
    [55] In addition, according to the present invention, since the grill body is configured to be separable into the first body portion and the second body portion, when the dirt attached to the grill body is removed, the second body portion can be separated and washed easily. The convenience of using a cleaner can be improved.
    [56] While the invention has been described and illustrated in connection with a preferred embodiment for illustrating the principles of the invention, the invention is not limited to the configuration and operation as such is shown and described. Rather, those skilled in the art will appreciate that many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims. Accordingly, all such suitable changes, modifications, and equivalents should be considered to be within the scope of the present invention.
