Description

cleaner

The present invention relates to a vacuum cleaner, and more specifically to a vacuum cleaner that can be easily operated.

In general, a vacuum cleaner is a home appliance that sucks in small trash or dust by sucking air using electricity and fills the dust bin inside the product, and is commonly called a vacuum cleaner.

These vacuum cleaners can be divided into manual vacuum cleaners, in which the user moves the vacuum cleaner while performing cleaning, and automatic vacuum cleaners, in which the vacuum cleaner performs cleaning while traveling on its own. Depending on the type of cleaner, manual cleaners can be classified into canister-type cleaners, upright cleaners, hand-held cleaners, and stick-type cleaners.

In the past, canister-type vacuum cleaners were widely used as household cleaners, but recently, hand-held vacuum cleaners and stick vacuum cleaners, which provide improved convenience of use by providing a dust bin and vacuum cleaner body, are increasingly being used.

A canisty-type vacuum cleaner has its main body and suction port connected by a rubber hose or pipe, and in some cases, it can be used by inserting a brush into the suction port.

Hand Vacuum Cleaners maximize portability. Although they are light in weight, their length is short, so the cleaning area you can sit on may be limited. Therefore, it is used to clean localized areas, such as on a desk or sofa, or inside a car. Handheld vacuum cleaners can be used while standing, allowing cleaning without bending down. Therefore, it is advantageous for cleaning a wide area while moving.

US Patent Publication No. 8806710 is presented as a prior document. Prior literature relates to vacuum cleaner heads.

The prior literature includes a sole plate including a suction opening, a stirring device including a first stirring member that sweeps away dust from the carpet, and a second stirring member that sweeps away dust from hard surfaces. The second stirring member extends outward from the stirring device behind the first stirring member and has a lower surface resistance than the first stirring member. Various support members are rotatably mounted on the sole plate to support the cleaner head on the cleaning surface. The first stirring member does not protrude below the plane extending between the lower ends of the support members. The second stirring member protrudes below a plane extending between the lower ends of the support members.

In the case of the prior literature, the first stirring member is spaced apart from the inner surface of the housing to form a gap, and the second stirring member reaches the inner surface of the housing. If the end of the second stirring member is worn or deformed into a spiral shape due to rotational inertia, a gap may be formed between the end of the second stirring member and the inner surface of the housing. In this case, the intake air flows separately below and above the stirring device, and the air flowing above the stirring device acts as resistance and becomes a factor that reduces cleaning performance.

The detailed configuration of the cleaning module 100 will be described later.

The extension pipe (not shown) is a component that connects the cleaning module 100 and the main body. The front end of the extension tube is coupled to the cleaning module 100 and connected to the cleaning module 100. The rear end of the extension tube is connected to the suction part of the main body.

The direction is defined with reference to FIGS. 3 and 4. In Figure 3, the downward direction is the front of the cleaning module 100. In Figure 3, the upward direction is the rear of the cleaning module 100. In Figure 3, the left direction is above the cleaning module 100. In Figure 3, the right direction is below the cleaning module 100. In Figure 4, the left direction is the left side of the cleaning module 100. In Figure 4, the right direction is the right side of the cleaning module 100.

With reference to FIGS. 1 to 4 , the configuration of the cleaning module 100 will be described.

The cleaning module 100 includes a housing 110. The housing 110 is a component that forms the external shape of the cleaning module 100.

The housing 110 forms the outer shape of the cleaning module 100 and creates a space inside where other components can be placed.

The housing 110 is coupled to the main body and includes an opening on one side that communicates the external space and the internal space.

The housing 110 is coupled to the main body (not shown). Referring to Figure 1, the rear end of the housing 110 is directly coupled to the main body or indirectly coupled to the main body through an extension pipe.

The housing 110 includes an opening on one side that communicates the external space and the internal space. Referring to FIG. 1, an opening is formed on the left side of the housing 110. Unlike shown in FIG. 1, the opening may be formed on the right side of the housing 110.

The cleaning module 100 includes an intake port 111. The intake port 111 is a hole that sucks in dust along with air.

Referring to FIG. 4, the suction port 111 is formed on the lower surface of the housing 110. The intake port 111 may be formed at the rear of the agitators 120 and 130.

The agitators 120 and 130 are inserted into the opening of the housing 110 and rotatably coupled to the housing 110.

The agitators 120 and 130 are formed in a cylindrical shape centered on a rotation axis. The rotation axes of the agitators 120 and 130 are arranged in the left and right directions.

The agitators 120 and 130 are disposed in front of the intake port 111. The agitators 120 and 130 sweep away dust adsorbed on the floor in front of the intake port 111. Dust adsorbed to the floor by the agitators 120 and 130 can be separated from the floor and more easily sucked into the suction port 111.

The agitators 120 and 130 are rotatably coupled to the housing 110. Referring to Figure 5, the agitators 120 and 130 rotate counterclockwise.

The cleaning module 100 may further include a motor (not shown) for rotating the agitators 120 and 130.

Referring to FIG. 4, a plurality of agitators 120 and 130 may be arranged in the cleaning module 100. Specifically, the agitators 120 and 130 may be divided into a front agitator 120 disposed relatively forward and a rear agitator 130 disposed relatively rear. Below, unless otherwise specified, it is established that the agitator refers only to the front agitator 120.

6 to 10, according to the first to third embodiments. The agitator 120 may be composed of an agitator bar 121, a bristle 122, and a blade 123.

The agitator 120 includes an agitator bar 121. The agitator bar 121 is a component that forms the outer shape of the agitator 120 and supports the bristle 122 or blade 123.

The agitator bar 121 forms a space inside and extends along the rotation axis.

The agitator bar 121 is formed in a cylindrical shape. Referring to FIG. 6, the agitator bar 121 may be formed in a cylindrical shape with the rotation axis disposed in the left and right directions and the left and right sides being open.

The agitator bar 121 may be formed of a hard material. For example, the agitator bar 121 may be made of a resin material.

The bristle 122 is a component that scrubs and cleans the cleaning area or separates adsorbed dust from the floor.

The bristles 122 are disposed on the outer circumferential surface of the agitator bar 121, and a plurality of bristles extend outward in the radial direction.

The bristle 122 is a collection of a plurality of bristles.

The bristle 122 may be arranged from the left end to the right end of the agitator bar 121 along the axial direction of the agitator 120.

The bristle 122 is disposed on a portion of the agitator bar 121 along the circumferential direction of the agitator 120. A plurality of bristles 122 are arranged to be spaced apart at a certain distance along the circumferential direction of the agitator 120.

The blade 123 is a component that scrubs and cleans the cleaning area or separates adsorbed dust from the floor.

The blade 123 is disposed on the outer circumferential surface of the agitator bar 121, and is disposed in the circumferential direction of the agitator 120 from the bristle 122.

The blade 123 is a protrusion extending in the axial direction. Specifically, the blade 123 protrudes from the agitator bar 121 outward in the radial direction of the agitator 120 and extends in the axial direction of the agitator 120.

The blade 123 may be formed of an elastic material. For example, the blade 123 may be made of rubber or resin.

The blade 123 may be divided into an extension part 1231, a blocking part 1232, and a connecting part 1233.

The extension portion 1231 extends from the agitator bar 121 outward in the radial direction of the agitator 120 .

The blocking portion 1232 extends from one side of the extension portion 1231 toward the bristle 122.

The connection portion 1233 connects the extension portion 1231 and the blocking portion 1232.

The blade 123 is spaced apart from the housing 110 of the cleaning module when the agitator 120 does not rotate, and comes into close contact with the housing 110 of the cleaning module when the agitator 120 rotates.

Referring to FIG. 7, when the agitator 120 does not rotate, the blade 123 is spaced apart from the housing 110 of the cleaning module. Referring to FIG. 8, when the agitator 120 rotates, the blade 123 comes into close contact with the cleaning module housing 110.

When the agitator 120 rotates, the blade 123 is deformed by centrifugal force and the blocking portion 1232 extends outward in the radial direction of the agitator 120. Accordingly, the blocking portion 1232 is in close contact with the cleaning module housing 110 and can block the upper flow between the agitator 120 and the cleaning module housing 110. Additionally, since the blocking portion 1232 is in close contact with the cleaning area, dust present in the cleaning area can be more effectively swept away.

Meanwhile, near the suction port, suction force generated by the suction motor may act on the blade 123. Specifically, when dividing the agitator 120 shown in FIG. 8 into upper and lower parts, suction force is applied to the blade 123 disposed at the lower part. Accordingly, the blade 123 disposed at the bottom is deformed more because suction force and centrifugal force are applied simultaneously.

For example, if the angle formed by the extension portion 1231 of the blade 123 disposed at the upper portion and the blocking portion 1232 is α, the extension portion 1231 of the blade 123 disposed at the lower portion and the blocking portion ( The angle formed by 1232) is β. At this time, α < β.

Suction force and centrifugal force are applied simultaneously from the bottom, causing the blade 123 to be more deformed, so that the blocking portion 1232 adheres more strongly to the cleaning area, which has the effect of more effectively sweeping away dust present in the cleaning area. .

The bristles 122 and blades 123 are alternately arranged along the circumferential direction of the agitator 120. Referring to FIG. 7, the bristles 122 and blades 123 are alternately arranged one by one along the circumferential direction of the agitator 120.

The blocking portion 1232 extends in the circumferential direction of the agitator 120. Referring to FIG. 7, the blocking portion 1232 and the ends of the bristle 122 may be arranged along an imaginary circle. The virtual circle does not contact the cleaning area. However, referring to FIG. 8, as the blade 123 is deformed when the agitator 120 rotates, the blocking portion 1232 protrudes to the outside of the virtual circle and is connected to the housing 110 of the cleaning module or May come into contact with cleaning area.

The blocking portion 1232 extends in a direction opposite to the rotation direction of the agitator 120. Referring to FIGS. 7 and 8 , the agitator 120 rotates counterclockwise, and the blocking portion 1232 extends clockwise from the extension portion 1231. The blocking portion 1232 may extend in the same direction as the rotation direction of the agitator 120 or in the opposite direction. However, if the blocking portion 1232 extends in the same direction as the rotation direction of the agitator 120, there is a risk that the blade 123 will bend when it contacts the cleaning module housing 110 or the cleaning area, and the blade 123 ) may be damaged, and scratches may be applied to the cleaning module housing 110 or the cleaning area. Therefore, it is preferable that the blocking portion 1232 extends in a direction opposite to the rotation direction of the agitator 120.

According to the first embodiment, the blade 123 may be connected by bending the connection portion 1233 between the extension portion 1231 and the blocking portion 1232. Referring to Figures 7 and 8, the extension portion 1231 is formed to be curved with a predetermined radius of curvature.

Unlike the blade 123 according to the second embodiment described later, the blade 123 according to the first embodiment does not have stress concentrated on the inner end of the connecting portion 1233, so the lifespan of the connecting portion 1233 is relatively high. Being long has its advantages.

However, the blade 123 according to the first embodiment may be more deformed than the blade 123 according to the second embodiment, due to friction between the blocking portion 1232 and the cleaning module housing 110 or the cleaning area. There is a disadvantage that the blocking portion 1232 can be easily worn.

According to the second embodiment, the blade 123 may be connected by bending the connection portion 1233 between the extension portion 1231 and the blocking portion 1232. Referring to FIG. 9, a bending point is formed in the extension portion 1231, and the extension portion 1231 and the blocking portion 1232 are bent and connected.

The blade 123 according to the second embodiment can be deformed less than the blade 123 according to the first embodiment, and the blocking portion 1232 does not protrude to the outside more than necessary, which has the advantage of less wear. .

However, according to the second embodiment, stress may be concentrated at the inner end of the connection portion 1233, which is a bending point, and there is a risk that the connection portion 1233 may be damaged when the blade 123 is greatly deformed.

According to the first embodiment, the blocking portion 1232 may extend from the end of the extension portion 1231. Referring to FIG. 7, the blocking portion 1232 extends from the end of the extension portion 1231 toward the bristle 122.

According to the third embodiment, the blocking portion 1232 may extend inside the end of the extension portion 1231. Referring to FIG. 10, the blocking portion 1232 extends toward the bristle 122 from an inner side than the end of the extension portion 1231. At this time, before the agitator 120 operates, the blade 123 is formed into an r-shape, and when the agitator 120 operates, the blade 123 is transformed into a Y-shape.

Hereinafter, an agitator according to the fourth embodiment will be described with reference to FIGS. 11 to 13.

Unlike the agitator 120 according to the first to third embodiments, the agitator 120 according to the fourth embodiment includes a blocking member 124 rather than a blade 123.

For the agitator 120 according to the fourth embodiment, the description of the agitator 120 according to the first to third embodiments may be used as long as it does not collide.

Hereinafter, the agitator 120 according to the fourth embodiment will be described focusing on the differences from the first to third embodiments.

The blocking member 124 is disposed on the outer circumferential surface of the agitator bar 121 and isolates one bristle 122 from the other bristle 122.

The blocking member 124 forms a hollow 1244 therein. Referring to FIG. 12, a hollow 1244 is formed inside the blocking member 124. The hollow 1244 extends in the axial direction of the agitator 120. Since the hollow 1244 is disposed inside the blocking member 124, the blocking member 124 may be deformed to be recessed to the radial inside of the agitator 120, or to be recessed to the radial outside of the agitator 120. It can also be transformed to protrude.

Referring to FIG. 12, the blocking member 124 may be divided into a first extension part 1241, a second extension part 1242, and a blocking part 1243.

The first extension portion 1241 extends from the agitator bar 121 to a radial outer side of the agitator 120 .

The second extension portion 1242 extends from the agitator bar 121 outward in the radial direction of the agitator 120 .

The blocking portion 1243 connects the first extension portion 1241 and the second extension portion 1242 and extends in the circumferential direction of the agitator 120.

The blocking portion 1243 is spaced apart from the housing 110 of the cleaning module when the agitator 120 does not rotate, and is deformed convexly in the radial direction of the agitator when the agitator 120 rotates to form a housing 110 of the cleaning module. ) is closely adhered to.

Referring to FIG. 12, when the agitator 120 does not rotate, the blocking member 124 is spaced apart from the housing 110 of the cleaning module. Referring to FIG. 13, when the agitator 120 rotates, the blocking member 124 comes into close contact with the cleaning module housing 110.

When the agitator 120 rotates, the blocking member 124 is deformed by centrifugal force and the blocking part 1243 is deformed to be convex outward in the radial direction of the agitator 120. Accordingly, the blocking portion 1243 is in close contact with the cleaning module housing 110 and can block the upper flow between the agitator 120 and the cleaning module housing 110. Additionally, since the blocking portion 1243 is in close contact with the cleaning area, dust present in the cleaning area can be more effectively swept away.

Meanwhile, near the suction port, the suction force generated by the suction motor may act on the blocking member 124. Specifically, when dividing the agitator 120 shown in FIG. 13 into upper and lower parts, suction force is applied to the blocking member 124 disposed below. Accordingly, the blocking member 124 disposed at the lower portion is deformed to be more convex as suction force and centrifugal force are applied simultaneously.

For example, if the radius of curvature of the blocking portion 1243 of the blocking member 124 disposed at the upper portion is R1, the radius of curvature of the blocking portion 1243 of the blocking member 124 disposed at the lower portion is R2. At this time, R1 > R2.

As suction force and centrifugal force are applied simultaneously from the bottom, the blocking member 124 is deformed more, and the blocking member 1243 adheres more strongly to the cleaning area, resulting in the effect of being able to more effectively sweep away the dust present in the cleaning area. there is.

The operation of the vacuum cleaner according to the present invention configured as above will be described as follows.

Referring to FIG. 7, when the agitator 120 does not rotate, the blade 123 is spaced apart from the housing 110 of the cleaning module. Referring to FIG. 8, when the agitator 120 rotates, the blade 123 comes into close contact with the cleaning module housing 110.

When the agitator 120 rotates, the blade 123 is deformed by centrifugal force and the blocking portion 1232 is in close contact with the cleaning module housing 110, causing a gap between the agitator 120 and the cleaning module housing 110. The upper flow can be blocked. Additionally, since the blocking portion 1232 is in close contact with the cleaning area, dust present in the cleaning area can be more effectively swept away.

Referring to FIG. 12, when the agitator 120 does not rotate, the blocking member 124 is spaced apart from the housing 110 of the cleaning module. Referring to FIG. 13, when the agitator 120 rotates, the blocking member 124 comes into close contact with the cleaning module housing 110.

When the agitator 120 rotates, the blocking member 124 is deformed by centrifugal force and the blocking part 1243 is deformed to be convex outward in the radial direction of the agitator 120. Accordingly, the blocking portion 1243 is in close contact with the cleaning module housing 110 and can block the upper flow between the agitator 120 and the cleaning module housing 110. Additionally, since the blocking portion 1243 is in close contact with the cleaning area, dust present in the cleaning area can be more effectively swept away.

In the above, preferred embodiments of the present invention have been shown and described, but the present invention is not limited to the specific embodiments described above, and can be used in the technical field to which the invention pertains without departing from the gist of the present invention as claimed in the patent claims.
