The present invention relates to a dust collecting unit mounting apparatus of a vacuum cleaner, and more particularly, after the first dust is collected by a cyclone method, a filter for collecting fine dust is mounted inside the dust collecting casing to clean the dust collecting casing. It relates to a dust collection unit mounting device configured to be mounted on the main body.

1 shows a configuration of a general vacuum cleaner. As shown in the drawing, the vacuum cleaner includes a main body 1 having a built-in suction device for sucking air in the room, and a suction part 2 into which air is introduced from the bottom surface by suction force generated in the main body.

The main body 1 includes a lower body 5 on which a suction device is installed; The upper body 6 is coupled to the upper portion of the lower body 5 and has a control unit (not shown) for controlling the vacuum cleaner. In addition, a plurality of wheels 8 are provided on the lower side of the main body 1 in the lower part of the main body 1 so that the main body 1 can smoothly move the bottom surface. The wheel 8 is formed with a discharge part 8a through which the air in which the foreign matter is separated from the air sucked through the suction part 2 is discharged from the main body 1.

In addition, between the main body 1 and the suction part 2, the suction hose (3b) made of a flexible material and connected to the end of the suction hose (3b), the user can perform the operation of the cleaner The operation part 4 and the extension pipe 3a etc. which connect the said operation part 4 and the suction part 2 are provided in order.

When electricity is applied through the electric wire 9 electrically connected to the built-in suction device of the main body 1, the vacuum cleaner is in a standby state. At this time, if the user adjusts the suction step by using the button of the operation unit 4, the suction force corresponding to each step is generated by the suction device built in the main body. The suction force generated through the suction device is transmitted to the suction part 2 through the suction hose 3b and the extension pipe 3a. By the suction force of the suction unit 2, air containing foreign substances such as dust is sucked in, and the foreign substances in the sucked air are filtered by the dust collecting unit (A). In addition, the filtered air is cleaned while being discharged to the outside of the main body 1 through the discharge portion 8a.

As described above, the dust collecting unit A is an important component for filtering foreign matter contained in the air sucked through the suction unit 2. The dust collecting unit A is mounted in a storage space formed between the lower body 5 and the upper body 6.

FIG. 2 is an exploded perspective view for explaining in detail the dust collecting unit A described schematically in FIG. 1. As illustrated, the dust collecting unit A includes a casing 7 having an upper portion opened, a cover 11 for opening and closing an upper portion of the casing 7, and a filter 12 mounted at a lower portion of the cover 11. It is configured to include).

The filter 12 is configured such that the upper surface 12a formed thereon can be fitted to or detached from the fastening portion 11a formed on the bottom surface of the cover 11. And the cover 11 which can attach / detach the filter 12 opens and closes the open upper part of the dust collection casing 7 with the upper part open.

And the handle 7b is shape | molded at the back surface of the casing 7, and it is comprised so that a user can hold the dust collecting casing 7. And the upper part of the handle 7b is formed with a frame portion 7h having an operating hole 7g. An operation member 7i is installed in the inner space of the frame portion 7h, and the operation button 7a of the operation member 7i is coupled to protrude through the operation hole 7g. An elastic body 7s is provided below the operation button 7a. Therefore, the operation button 7a is always elastically supported upward by the elastic body 7s inside the frame portion 7h. The upper portion of the operation member (7i) is formed with a locking projection (7c), the locking projection (7c), as described above, is elastically coupled to the inlet jaw (6t) of the cleaner body (1).

And the cover 7d is fixed to the upper part of the frame part 7h so that the operation member 7i may be detached from the inside of the frame part 7h.

Mounting the dust collection unit (A) having such a configuration to the vacuum cleaner body (1) is pushed into the storage space while pressing the operation button (7a) of the upper portion of the handle (7b) formed on the rear side, When the operation button 7a is released, the engaging projection 7c of the upper part of the operation member 7i is caught by the inlet jaw 6t of the upper body 6, and the dust collecting unit A is fastened to the main body 1. Will be maintained.

Here, it can be seen that the dust collecting unit A is mounted on the cleaner main body 1 regardless of whether the filter 12 is mounted on the cover 11. That is, according to the conventional filter mounting structure, the cover 11 can be mounted on the casing 7 even when the filter 12 is not mounted on the cover 11. Therefore, the dust collecting unit A can be coupled to the main body of the vacuum cleaner in the state where the filter 12 is not mounted due to a mistake of the user.

The dust collection unit (A) is relatively a primary dust collection by the cyclone method in which a large foreign matter falls downward while the air flowing through the inlet (11c) is formed in a spiral flow inside the casing (7), After the large foreign matter is filtered out, the fine dust is filtered through the filter 12 to perform a secondary dust collecting function.

Here, if the filter 12 is not mounted as described above, the bulky dust in the air introduced through the inlet 11c falls downward due to its own weight in the spiral flow and falls below the separation plate 7m. , Fine dust is introduced into the main body 1 through the outlet (11b) without being filtered. Therefore, there is a concern that the internal parts may be broken due to the problem of the cleaning efficiency in which the fine dust and the like are not substantially filtered and the fine dust flowing inside the cleaner body.

According to the conventional structure, as described above, even when the vacuum cleaner is operated in the state in which the filter 12 is not mounted, there is no device that can inform the user of this.

 The present invention has been made to solve the above problems, and an object of the present invention is to provide a filter mounting apparatus in which a filter for filtering fine dust can be accurately mounted on the cover of the dust collecting unit.

That is, according to the present invention, in the state where the filter is not attached to the dust collecting unit, the dust collecting unit is configured not to be mounted on the vacuum cleaner main body, so that the vacuum cleaner can be prevented from being driven without the filter.

The vacuum cleaner filter mounting apparatus according to the present invention is a device for inserting a dust collection unit into a mounting space formed on one side of the vacuum cleaner main body; a casing with an open upper portion; A cover having a protrusion protruding upward to form a right angle in cross section, a fastening hole formed at the rear of the protrusion, and a fastening protrusion having a curved surface passing through the fastening hole when the cover is mounted on the lower surface of the cover and having a curved surface at a rear end thereof. A dust collecting unit including a filter including a molded upper frame, a dust collecting unit installed in an upper portion of a mounting space into which the dust collecting unit is inserted, a control unit protruding out of the main body, and a lower end projecting downward of the mounting space; And a latch elastically supported about a hinge axis such that the lower end faces downward of the mounting space, wherein the filter is mounted on the bottom of the cover. In the state, the lower end of the latch rises along the rear end surface of the fastening protrusion so that the dust collecting unit can be mounted in the mounting space, and in the state where the filter is not mounted, the lower end of the latch is not caught on the rear end surface of the protrusion. I am doing it.

According to the embodiment, the cover further comprises a coupling rib coupled to the lower end of the latch when the dust collecting unit is completely inserted into the mounting space.

And according to another embodiment, a plurality of engaging pieces protruded at regular intervals radially outward from the upper frame on the plane of the filter; By means of a coupling support piece which is shaped to be spaced apart from the cover bottom with a number corresponding to the coupling piece and spaced apart from the cover bottom by being inserted therebetween, the coupling piece is formed so as to be sandwiched with the cover bottom by being rotated at regular intervals. Is attached to and detached from the lower surface of the cover.

Next, the present invention will be described in more detail with reference to the embodiments of the present invention shown in the drawings.

3 is an exemplary view showing a process in which the dust collecting unit 50 having the configuration according to the present invention is mounted to the mounting space 110 of the cleaning main body 100, and FIG. 4 is for the upper portion of the dust collecting unit according to the present invention. An illustrative perspective view.

Looking at the present invention with reference to this, the dust collecting unit 50 of the present invention is mounted by being inserted into the mounting space 110 formed on one side (for example, the rear end) of the cleaning base 100. In addition, the dust collecting unit 50 filters the foreign matter contained in the air to be sucked in the state mounted on the main body 100.

For example, the filtering of the dust collecting unit 50, the first dust to collect the relatively heavy foreign matter by the cyclone method to the air introduced into the interior, and the second to collect relatively fine air by the filter after the first dust It can be divided into dust collection.

As shown in the figure, the dust collecting unit 50 is detachably attached to a casing 30 having an upper end opened, a cover 60 coupled to an upper end opening of the casing 30, and a lower portion of the center of the cover. It is configured to include a filter 40 to be combined.

First, the filter 40 will be described. As shown in FIG. 3 and FIG. 5, the filter 40 forms the vertical filter part 42 shape | molded to the hollow cylinder inside, and the upper part of the said filter part 42, and forms the flat composite water. The upper frame 44 is made of ash. In addition, the lower end of the filter 40 is made of a synthetic resin material and a lower frame 46 for supporting the filter unit 42 is formed.

In addition, a fastening protrusion 48 protruded upward is formed on an upper portion of the upper frame 44 of the filter 40. The rear end surface 48a of the fastening protrusion 48 is molded to have a smooth curved surface having a round.

The filter 40 is detachably assembled to the lower surface of the cover 60 shown in FIGS. 3 and 6. Looking at one embodiment for attaching and detaching the filter 40 to the cover 60, as shown in Figure 5 and 6, the outer periphery of the upper frame 44 of the filter 40, a plurality of The joining piece 44a is radially extended at regular intervals. Between the coupling pieces 44a, coupling recesses 44b formed in the original shape will be formed. And the lower surface 62 of the said cover 60 is shape | molded by the fixed support piece 64a which has the same space | interval as the said engaging piece 44a at fixed intervals with the lower surface 62. As shown in FIG. Therefore, when the coupling piece 44a is inserted at intervals between the coupling support pieces 64a and rotates at a predetermined interval, the coupling piece 44a is disposed between the coupling support pieces 64a and the lower surface of the cover 62. The filter 40 is substantially engaged with the bottom surface 62 of the cover 60.

The cover 60 is formed with a fastening hole 66 into which the fastening protrusion 48 can be inserted from below. Therefore, in the state in which the filter 40 is coupled to the cover 60, as shown in FIGS. 3 and 4, the fastening protrusion 48 will protrude upward through the fastening hole 66.

3, the projection 68 protruded from the upper surface of the cover 60 to the upper part of the part in which the said fastening hole 66 is shape | molded is shape | molded. . The rear end surface 68a of the projection 68 is molded to form a right angle.

Coupling ribs 69 are formed on the upper surface of one side of the cover 60 (left side in the drawing). As described later, the coupling rib 69 may maintain the state in which the dust collecting unit 50 is coupled to the main body 100 by joining with the lower end 124 of the latch 120 of the main body 100. It is to ensure that.

A latch 120 is provided at the upper end of the mounting space 110 of the main body 100 of the vacuum cleaner. The left end (manipulation part) 125 of the latch 120 protrudes to the left of the main body 100, and the right end (lower end) 124 is configured to protrude into the mounting space 110. . In addition, the latch 120 is rotatably installed around the hinge shaft 122, and is installed such that the latch 120 is always elastically supported in the clockwise direction about the hinge shaft 122. For example, by inserting and installing the torsion spring in the hinge shaft 122, the latch 120 can always be elastically supported in the clockwise direction, and thus the lower end portion 124 of the hinge shaft 122 Is always maintained in a state protruding downward toward the mounting space (110).

Next, a process in which the dust collecting unit 50 according to the present invention is mounted on the mounting space 110 of the cleaner body 100 will be described with reference to FIG. 3.

First, the dust collection unit 50 should be coupled to the filter 60 in the cover 60, the dust collection unit 50, can be combined by inserting into the mounting space 110 of the main body 100 It becomes a state. That is, the filter 40 is mounted on the bottom surface of the cover 60, and thus, as shown in FIG. 4, the fastening protrusion 48 of the filter 40 is upper through the fastening hole 66 of the cover 60. It is in the state which protruded.

In such a state, when the dust collecting unit 50 is inserted into the mounting space 110 of the main body 100, the rear end surface 48a of the fastening protrusion 48 protruding to the upper portion of the cover 60 is latched. It comes in contact with the lower end 124 of 120. However, since the rear end surface 48a of the fastening protrusion 48 is formed into a curved surface having a round, the lower end portion 124 of the latch 120 is not directly interfered with the lower end portion 124 of the latch 120. ) Is upwardly lifted (while the latch 120 rotates counterclockwise about the hinge shaft 122), the dust collecting unit 50 can be continuously inserted into the mounting space 110.

When the dust collecting unit 50 is further inserted, the lower end portion 124 of the latch 120 contacts the right inclined surface 69a of the coupling rib 69, in which the lower end portion 124 is engaged. The right inclined surface 69a of the rib 69 is crossed over. And when the dust collecting unit 50 is completely inserted, the lower end portion 124 is in close contact with the left side of the coupling rib 69, it is possible to maintain the complete coupling state of the dust collecting unit 50.

Here, the case in which the filter 40 is not coupled to the cover 60 will be described. If the filter 40 is not coupled, the fastening protrusion 48 does not protrude above the fastening hole 66 of the cover 60.

Therefore, when the dust collecting unit 50 is inserted into the mounting space 110 in this state, the lower end 124 of the latch 120 comes into contact with the protrusion 68 protruding to the upper portion of the cover 60. At this time, since the rear end surface 68a of the protrusion 68 is almost perpendicular to the lower end 124 of the latch 120, the dust collecting unit 50 is no longer mounted. It will not be possible to insert it into the

That is, the lower end portion 124 of the latch 120 is caught by the rear end surface 68a of the protrusion 68 of the cover 60, thereby substantially inserting the dust collecting unit 50 into the mounting space 110. It is impossible. In this state, since the entire dust collecting unit 50 is not completely inserted into the mounting space 110, the user of the vacuum cleaner sees the unmounted state of the dust collecting unit 50, and thus the filter 40 is not installed. You will notice that it is not mounted. Therefore, the dust collecting unit 50 is removed again, and the filter 40 will be mounted on the bottom of the cover 60.

Thus, it can be seen that the present invention is configured such that the dust collecting unit 50 is not mounted to the main body 100 of the vacuum cleaner in the state where the filter 40 is not mounted. Therefore, it can be seen that the vacuum cleaner cannot be operated substantially in the state where the filter 40 is not mounted.

As described above, according to the present invention, due to the configuration of the fastening protrusion 48 formed on the upper frame of the filter, in the state in which the filter 40 is not attached to the cover 60, the dust collecting unit 50 It can be seen that the basic technical idea is to configure itself so as not to be mounted in the mounting space 110 of the vacuum cleaner body 100.

And within the scope of the basic technical spirit of the present invention as well as many other modifications to those skilled in the art, of course, the present invention should be construed by the appended claims.

According to the present invention configured as described above it can be expected the following effects.

According to the present invention, if the filter is not installed inside the dust collecting unit which separates and collects the foreign matter from the suction air, the dust collecting unit cannot be coupled to the main body of the vacuum cleaner, so that the vacuum is not attached to the dust collecting casing. Driving the cleaner can be prevented in advance. Therefore, it is possible to completely solve the problem caused by the driving of the cleaner in the state that the filter is not mounted, it is expected that the advantage that can substantially increase the reliability of the vacuum cleaner. In addition, in the assembly process of the product, it is also possible to expect additional convenience that can prevent the omission of the assembly of the filter.
