Vacuum cleaners are widely used in general households, and the demand is increasing due to the necessity of cleaning carpets and sofas, and a canister type in which a nozzle part, which is a suction port, is provided separately from the main body and connected by a connecting pipe. And it can be roughly divided into an upright method (Upright type) in which the nozzle unit is formed integrally with the main body.

The filter assembly of the vacuum cleaner performs a function of separating and collecting the foreign matter in the inhaled air. Hereinafter, the suction nozzle of the vacuum cleaner that can be installed in all types of vacuum cleaners, as well as the canister type and the upright type. It demonstrates.

In general, the suction nozzle moves in a state close to the floor of the room, and serves to guide the foreign matter attached or accumulated on the floor to be introduced into the main body (not shown).

3 is a perspective view of a bottom surface of the cleaner suction nozzle according to the present invention, and FIG. 4 is a bottom view of the bottom surface of the cleaner suction nozzle according to the present invention. 5 to 7 show respective partial cross sections of FIG. 4.

As shown in these figures, the suction port 50 is formed through the center of the nozzle bottom surface 40 of the suction nozzle. The suction port 50 is an inlet in which foreign matter attached to the floor of the room or foreign matter accumulated on the floor is sucked into the suction nozzle.

The suction channel 60 is formed to communicate with the left and right sides of the suction port 50. The suction passage 60 is overlapped to have at least two aromatic components, and serves as a passage for guiding outside air and foreign matter to the suction port 50.

The suction flow path 60 is shaped into an 'S' shape as shown. That is, as shown in Figure 3, the suction flow path 60 is formed recessed inward from the bottom surface, it is molded to have a 'S' shape as a whole. Of course, the suction flow path 60 as described above may be molded in a zigzag shape or other shapes in addition to the 'S' shape.

Since the suction passage 60 has a 'S' shape as described above, the suction passage 60 has a shape overlapping each other. That is, the suction flow path 60 is composed of three flow paths as shown, and overlap each other.

Looking in more detail, the central flow path 52 is formed on the left and right of the inlet port 50 to guide the left and right air to the intake port 50, the front flow path 54 is in front of the central flow path (52) The rear channel 56 is formed at the rear side of the central channel 52. The front channel 54 is formed in front of the central channel 52 to guide the air flowing from the left side to the central channel 52. In addition, the rear channel 56 is formed at the rear of the front channel 54 to serve to guide the air flowing from the right side to the central channel 52.

The bottom surfaces of the front flow passage 54 and the rear flow passage 56 are not formed at the same position. That is, the bottom surfaces of the front flow passage 54 and the rear flow passage 56 are flat surfaces 54 'and 56' formed at the same height as the bottom surface of the central flow passage 52, and the flat surface 54 And 56, the inflow surfaces 54 ", 56", and the like that gradually increase in height away from '56'.

More specifically, the bottoms of the center and right portions of the front passage 54 are formed at the same position (height) as the central passage 52 to form the front flat surface 54 ', and the front flat surface 54 ') Forms a plane parallel to the nozzle bottom surface 40. The bottom portion of the left side of the front flow passage 54 forms a front inflow surface 54 ″ in which the formation position thereof gradually increases toward the left side. The left end of the front inflow surface 54 ″ has a left side described below. Inlet 58 is formed.

Bottoms of the center and left portions of the rear channel 56 are formed at the same position (height) as the central channel 52 to form a rear flat surface 56 ', and the rear flat surface 56' is the nozzle. A plane parallel to the bottom surface 40 is formed. The bottom portion of the right side of the rear flow passage 56 forms a rear inflow surface 56 ″ in which the formation position thereof gradually increases toward the right side. The right end of the rear inflow surface 56 ″ has a right side to be described below. Inlet 58 'is formed.

A partition wall 70 having a predetermined height is formed between the suction passages 60 overlapping as described above. The partition wall 70 serves to partition adjacent suction flow paths 60 from each other. That is, the partition wall 70 allows the central passage 52, the front passage 54, and the rear passage 56 to be partitioned from each other.

More specifically, a bulb wall 72 is formed between the central flow passage 52 and the front flow passage 54 so as to partition the central flow passage 52 and the front flow passage 54 so as to be separated from each other. A rear partition wall 74 is formed between 52 and the rear flow passage 56 to partition the central flow passage 52 and the rear flow passage 56 from each other.

The partition wall 70 has a configuration in which a width (thickness) is variable. That is, the width (thickness) of the partition wall 70 is formed to gradually decrease from the outside to the inside. Looking more specifically, the partition wall 70 is formed such that its width (thickness) gradually increases or decreases toward one side. That is, as shown, the width of the bulb partition wall 72 is gradually reduced toward the right side, the rear partition wall 74 is formed so that the width gradually decreases toward the left side.

In addition, the cross-sectional area of the suction flow path 60 is preferably formed such that the sizes thereof are not equal to each other at each position. That is, the suction flow path 60 is formed such that the size of the cross-sectional area gradually increases from both ends to the inside. In particular, the front flow passage 54 and the rear flow passage 56 are formed such that the size of the cross-sectional area gradually increases from the left end or the right end toward the inside.

The suction flow path 60 is formed such that its width L gradually increases or decreases toward one side. That is, the suction flow path 60 has a size smaller than the width of the inner end width. However, it is preferable that the central passage 52 has a configuration in which the width thereof is not changed.

In more detail, inflow ports 58 and 58 ′ communicating with the outside are formed at the left end of the front flow path 54 and the rear flow path 56, respectively. That is, the left inlet 58 is formed at the left end of the front inlet 54, and the right inlet 58 ′ is at the right end of the rear inlet 56. Are each formed, and the left inlet 58 and the right inlet 58 'are inlets through which external air flows from the side (left and right) into the front passage 54 and the rear passage 56, respectively.

In addition, the cross-sections of the inlets 58 and 58 'have a size smaller than the cross-sectional areas of the front passage 54 and the rear passage 56. That is, the width L ′ of the left inlet 58 formed at the left end of the front flow passage 54 has a smaller size than the width L ″ inside the front flow passage 54.

More specifically, the width L of the front flow passage 54 increases gradually from the left end to the right end of the front inflow surface 54 ″, and the width of the rear flow passage 56 is increased. L gradually increases in size from the right end to the left end of the rear inflow surface 56 ″.

In addition, the depth (H) of the suction flow path 60 is also different in size depending on the position, in particular, the depth (H) gradually increases from both ends to the inside. At this time, the lower end (the upper end in FIGS. 3 and 4) of the partition wall 70 is formed to be coplanar with the bottom surface of the suction nozzle, so that the depth of the suction channel 60 and the partition wall 70 at any position. ) Are all the same, which becomes 'H' in FIG.

In more detail, the size of the depth H gradually increases from the left end to the right side, and the depth H of the front wall 72 is the same. The depth H of the rear flow passage 56 and the rear partition wall 74 gradually increases from the right end to the left.

In this way, the width L of the front flow passage 54 and the depth H of the bulb wall 72 gradually increase in magnitude from the left end to the right, and the width L of the rear flow passage 56. ) And the size of the depth H of the rear partition wall 74 gradually increases from the right end to the left side, and naturally, the cross-sectional area size of the front flow passage 54 gradually increases from the left end to the right side and the rear side. The cross-sectional area size of the flow path 56 gradually increases from the right end to the left side.

A recess 80 is further formed in the partition wall 70. The groove 80 serves to enable the flow of air between the suction passages 60 adjacent to each other. That is, the front recess 82 is formed in the bulb partition wall 72 to guide the air flow between the front flow passage 54 and the central flow passage 52, and the rear recess wall 74 is formed in the rear recess wall 74. 84 is formed to guide the air flow between the rear flow passage 56 and the central flow passage 52.

The grooves 80 are formed in plural, and the grooves 80 are preferably formed at equal intervals along the partition wall 70. In addition, the grooves 80 formed in the adjacent partition wall 70 are formed so that their formation positions are shifted from each other. That is, as illustrated, the front recess 82 formed in the bulb partition wall 72 and the rear recess 84 formed in the rear partition wall 74 are alternately formed.

As described above, the front recesses 82 and the rear recesses 84 are shifted from each other in order to make the vortex more easily occur. That is, the flow of air passing through the front recess 82 and from the front passage 54 to the central passage 52, and through the rear recess 84, pass the rear passage 56 from the rear passage 56. The flow of air to (52) forms a vortex by interacting with each other to facilitate the generation of such a vortex.

The depths h of the plurality of recesses 80 are the same, respectively. In addition, the depth h of the recess 80 is preferably formed to have a size smaller than the height H of the partition wall 70 at the point where the recess 80 is formed or the depth of the suction passage 60. Do. In addition, the left and right width m of the groove 80 is preferably formed to have a size smaller than the distance (M) between the grooves 80, more specifically, is formed to have a size of about 5mm.

Thus, the reason for limiting the size of the groove 80, the suction flow path 60 is the main movement passage of the air and foreign matter and the groove 80 is the auxiliary movement passage of the air, relatively the groove 80 Through this is to allow a smaller amount of air to flow than the suction passage (60).

On the other hand, right and left of the inlet 50 is provided with a semi-circular guide surface 90 for smooth inflow of air and foreign matter, respectively. That is, both ends of the suction port 50 are provided with a guide surface 90 having a shape of ')' and '('), and the air and the foreign matter introduced from the left and right through the central flow path 52 have a large friction with the suction port 50. Easily flow in without

Hereinafter, the operation of the suction nozzle bottom structure of the cleaner will be described with reference to FIGS. 3 to 8.

When the user supplies power to the cleaner, a suction force is generated by the rotation of the motor (not shown) and the fan of the cleaner, and the suction force is transmitted to the suction port 50 of the suction nozzle, so that the air and the foreign substance under the suction nozzle. This is forced to flow through the suction port 50.

Therefore, when the user comes into close contact with the suction nozzle on the carpeted floor, the suction of air and foreign matters starts. At this time, air and foreign matter are first introduced through both ends of the suction passage (60). That is, outside air and foreign matter are introduced and flow inward through the inlets 58 and 58 'formed at the left end of the front passage 54 and the right end of the rear passage 56.

Air and foreign matter flowing through the front flow passage 54 and the rear flow passage 56 are changed in direction at the right end of the bulb partition wall 72 and the left end of the rear partition wall 74, respectively, so that the central flow path is changed. Flows into (52). Therefore, air and foreign matter introduced from the left and right of the central passage 52 enter the suction nozzle through the suction port 50.

At this time, the flow of air and dust also occurs through the groove (80). That is, the air moving through the front channel 54 through the front recess 82 moves to the central channel 52 through the bulb projection wall 72 and through the rear recess 84. Passes through the rear partition wall 74 and moves to the central flow path 52.

As such, the air passing through the front recess 82 and the rear recess 84 to the central flow passage 52 forms a swirl by interaction. That is, since the front recess 82 and the rear recess 84 are formed to be staggered with each other, naturally causing a swirl in the central flow passage 52, the state at this time is shown in detail.

Referring again to the flow of air and foreign matter with reference to Figure 8, the air velocity is relatively at the left end of the front passage 54 and the right end of the rear passage 56 which is the first inflow passage of the air and foreign matter introduced from the left and right Faster. This is because the cross-sectional area of the left end of the front passage 54 and the right end of the rear passage 56 has a size smaller than that of the suction passage 60 of the other portion.

And, most of the air and foreign matter flows left and right along the front flow path 54 and the rear flow path 56, the main flow path to the central flow path 52, a portion of which passes through the groove (80). To the central flow path (52).

In this case, since the cross-sectional area of the groove 80 has a size smaller than that of the suction channel 60, the speed of the air passing through the groove 80 is the speed of the air moving through the suction channel 60. Have a relatively higher speed. Therefore, a strong swirl is formed in the central flow path 52, and foreign matter such as sand buried in the carpet is easily supported by the swirl and flows into the suction port 50.

More specifically, if the user pushes the suction nozzle in close contact with the carpet, the carpet of the carpet is pressed by the bottom surface of the suction nozzle or a scraper (not shown). foreign matter between the (pile) is hidden. At this time, when the swirl occurs as described above, foreign matters such as sand buried between the laid hairs are supported to escape from the hairs and flow into the suction port 50. will be.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

For example, in the above embodiment, the front recess 82 formed in the bulb partition wall 72 and the rear recess 84 formed in the rear partition wall 74 are configured to be offset from each other. It is not necessary to shift the 80 when it is supported, and it may be possible to form the front recess 82 and the rear recess 84 so as not to shift each other. Of course, at this time, a vortex of a different shape from the vortex shown in FIG. 8 will be generated.

In addition, unlike the above embodiment, the configuration as shown in FIG. 9 may be possible. That is, in FIG. 9, the edge guide 92 protrudes upward along the edge of the suction flow path 60. That is, the edge guide 92 protruding round the upper surface is projected upwardly along the outer edge of the suction flow path 60, the edge guide 92 is the nozzle bottom surface 40 is the floor of the room When the cleaning is performed while moving in close proximity to the surface, air is prevented from entering the suction flow path 60 through other portions of the inlets 58 and 58 ', thereby preventing the loss of suction force.

In the vacuum cleaner suction nozzle bottom structure according to the present invention as described above, the suction passage is molded into an 'S' shape or a zigzag shape so that two or more of the suction passages have an aromatic component. Therefore, since the suction area is relatively wider than the conventional one, there is an advantage that the cleaning efficiency is improved.

In addition, partition walls are formed between the overlapping suction flow paths, and a plurality of grooves are formed in the partition walls at predetermined intervals. The grooves formed in the adjacent partition walls are formed to be offset from each other. Therefore, in the central flow path, a swirl is formed by the flow of air flowing in the front and rear grooves, so that foreign matters such as sand grains embedded in the carpet are easily supported and sucked.

In addition, since the inlet flow passage is formed so that the cross-sectional area of the left and right ends is relatively smaller than the inner portion, a large difference in surface pressure (area pressure) occurs between the vicinity of the intake port and the inlet (left and right ends) of the intake passage. Stronger swirls are formed in the. Therefore, there is an effect that the suction ability of the foreign matter is further improved.
