  Hereinafter, a vacuum cleaner 1000 according to an embodiment of the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, a vacuum cleaner 1000 according to an embodiment of the present invention includes a dust collector 100, a suction device 200, and an air guide tube 300.

  Specifically, the suction device 200 includes an intake port 21 and an exhaust port 22. The dust collector 100 includes an air inlet 201 provided on the bottom wall of the dust collector 100 and an air outlet 301 that communicates with the air inlet 21 of the suction device 200. By sucking air with the suction device 200, the suction port 21 of the suction device 200 communicates with the air outlet 301 of the dust collector 100, so a suction force is formed in the dust collector 100, and dust-containing airflow is generated. It enters the dust collector 100 from the air inlet 201 of the dust collector 100. After the dust collector 100 separates dust and air from the dust-containing airflow, dust and other contaminants accumulate in the dust collector 100, but the airflow then flows to the suction device 200. In addition, the gas is discharged through the exhaust port 22 of the suction device 200. Thereby, circulation of airflow is formed, and dust and the like are accumulated in the dust collector 100. The air duct 300 communicates the dust collector 100 with the outside, is provided close to the bottom wall of the dust collector 100, and communicates with the air inlet 201 of the dust collector 100.

  In the vacuum cleaner 1000 according to the embodiment of the present invention, the air inlet 201 is provided in the bottom wall of the dust collector 100, and the air guide pipe 300 is provided in the dust collector 100 in the vicinity of the bottom wall of the dust collector 100. And communicates with the air inlet 201. Thus, the fact that the air inlet 201 is provided in the bottom wall of the dust collector 100 is that the present invention shortens the length of the duct of the air guide pipe 300 as compared with the traditional side dust collector. Therefore, the dust collector 100 has a large suction force, so that the dust-containing air current can be quickly passed through the air inlet 201 so that the dust and the air in the dust collector 100 are separated. It is possible to improve the dust absorption efficiency of the vacuum cleaner by entering the dust collector 100.

  As shown in FIG. 1, in some specific embodiments of the present invention, the suction device 200 includes a casing 4, an intake airflow stabilization cover 5, an exhaust machine inner cover 6, and an exhaust machine outer cover 7. Including the exhaust unit 8.

  Specifically, an intake port 21 and an exhaust port 22 are respectively provided in the casing 4. An inlet airflow stabilizing cover 5 is provided in the casing 4 and communicates with the air inlet 21 so that the inlet airflow stabilizing cover 5 is used to stabilize the airflow. It is possible to make it enter gently. An exhaust machine inner cover 6 is provided in the casing 4, and an exhaust hole 61 is provided in the exhaust machine inner cover 6. Exhaust device outer cover 7 is provided on the inner wall surface of casing 4, and in combination with the inner wall surface of casing 4, one end communicates with exhaust port 22 and forms the first airflow passage 71 having the other end opened, In addition, the exhaust outer cover 7 and the exhaust inner cover 6 form a second air flow passage 72 that communicates with the first air flow passage 71 and the exhaust hole 61 with a space therebetween. The exhaust unit 8 is provided in the exhaust unit cover 6, the exhaust unit inlet of the exhaust unit 8 communicates with the airflow stabilizing cover 5 for intake air, and the exhaust unit outlet of the exhaust unit 8 communicates with the exhaust unit cover 6. doing.

  As a result, the casing 4, the exhaust cover 6 and the exhaust cover 7 can be adopted and combined to form a long air passage. Therefore, the noise can be reduced by causing the airflow to detour from the exhaust hole 61 and flowing to the exhaust port 22 to make the airflow discharged from the exhaust port 22 gentle.

  Further, a muffler chamber 73 communicating with each of the first airflow passage 71 and the second airflow passage 72 protrudes from the casing 4 to the outside. Thereby, the silencing effect can be further improved.

  Preferably, a muffler chamber 73 is provided at one end of the opening of the first airflow passage 71.

  Specifically, the airflow is exhausted from the outlet for exhauster 8 into the exhauster cover 6 and then the airflow sequentially passes through the second airflow passage 72, the silencer chamber 73, and the first airflow passage 71. Thereafter, the air is discharged from the exhaust port 22 to the outside of the vacuum cleaner 1000. During the airflow process, the noise of the vacuum cleaner 1000 can be reduced because it passes through the muffler passage such as wide-narrow-wide-narrow-wide.

  Preferably, a sound deadening sponge 91 is provided at the exhaust port 22. Thereby, the silencing effect of the vacuum cleaner can be further improved.

  As shown in FIG. 2, in some embodiments of the present invention, a vacuum cleaner dust collecting device 100 includes a cyclone separator 1, a dust cup 2, and an upper lid 3 of the dust cup.

  Specifically, an air inlet 201 is provided in the bottom wall of the dust cup 2, and has a cyclone separator inlet 101 and a cyclone separator outlet 102, and the cyclone separator inlet 101 communicates with the air inlet 201. A container 1 is provided in the dust cup 2. An upper lid 3 of a dust cup provided with an air outlet 301 communicating with the cyclone separator outlet 102 is provided so as to cover the dust cup 2. Dust-containing air is sucked into the dust collector 100 through the air inlet 201 and then filtered by the dust collector 100. During the filtration process, dust and the like are accumulated in the dust cup 2, but the filtered air is exhausted from the cyclone separator 1 through the cyclone separator outlet 102 and enters the upper lid 3 of the dust cup. It is discharged from the dust collector 100 via 301.

  As a result, the dust collector 100 adopts a structure in which air enters from the bottom, greatly reducing the distance from the cyclone separator inlet 101 to the air inlet 201, and in the vacuum cleaner of the air guide pipe communicating with the air inlet 201. The length is shortened. Therefore, power loss can be reduced, a large space can be saved in the entire vacuum cleaner, and the manufacturing cost can be reduced. Moreover, since the air inlet 201 is located on the bottom wall of the dust cup 2, the dust collection capacity of the dust cup 2 increases. Further, the suction efficiency of the entire vacuum cleaner having the dust collecting device 100 can be greatly improved without early reduction due to clogging of the filter screen, and the cleaning cycle of the filter screen can be extended.

  Preferably, a filter net 92 is provided in the upper lid 3 of the dust cup. Thereby, the filtration effect of a vacuum cleaner further increases.

  As shown in FIG. 2, the dust collector 100 further includes an inlet pipe 17 whose both ends communicate with the inlet 201 and the cyclone separator inlet 101, respectively. Specifically, referring to FIG. 2, the lower end of the inlet pipe 17 communicates with the inlet 201, but the upper end of the inlet pipe 17 communicates with the cyclone separator inlet 101. Thereby, the connection between the cyclone separator 1 and the dust cup 2 becomes convenient, and the mounting property of the cyclone separator 1 is improved. In addition, the air inlet 201 and the cyclone separator inlet 101 communicate with each other through the inlet pipe 17, thereby facilitating the flow of airflow containing dust, and the connection between the cyclone separator 1 and the dust cup 2 becomes convenient. The mounting property of the cyclone separator 1 is improved.

  Since it is not necessary to use a special plastic material for the inlet pipe 17 in the present invention, the molding cost of the inlet pipe 17 can be reduced.

  In addition, since the air inlet 201 is provided in the bottom wall of the dust cup 2, in the conventional technology, the inlet pipe 17 is connected to the side wall of the dust cup 2, thereby connecting the inlet pipe 17 and the dust cup 2 to each other. The problem of poor sealing performance can be solved. When the inlet pipe 17 in the present invention is connected to the bottom wall of the dust cup 2, the sealing function between the inlet pipe 17 and the bottom wall of the dust cup can be improved. As a result, the suction force when the cleaner having the dust collecting device 100 is working is improved, and the dust suction efficiency of the cleaner can be improved. Since the inlet pipe 17 is connected to the bottom wall of the dust cup 2, the inlet pipe 17 is connected to the arc-shaped side wall of the dust cup in the conventional technique, so that the end shape structure is complicated and difficult to process. Can solve the problem. Furthermore, since it is not necessary to use a special plastic material for the inlet pipe of the present invention, the molding cost of the inlet pipe 17 can be reduced.

  Preferably, the lower end of the inlet pipe 17 is locked to the bottom wall of the dust cup 2. Specifically, as shown in FIGS. 2 and 3, an annular locking groove 172 is provided on the outer wall surface at the lower end of the air inlet pipe 17, and the periphery of the air inlet 201 of the dust cup 2 is the annular locking groove. It is locked in 172. This stabilizes the engagement between the lower end of the air inlet pipe 17 and the bottom wall of the dust cup, and improves the sealing function of the connecting portion between the air inlet pipe 17 and the bottom wall of the dust cup.

  As the cyclone separator 1 according to the present invention, a cyclone separator according to the prior art in which an inlet for a cyclone separator is provided on the side wall of the cyclone cylinder can be adopted, and the inlet for the cyclone separator and the inlet are communicated via a connecting pipe. . Of course, a new cyclone separator 1 is also provided in the present invention. Hereinafter, the structure of the cyclone separator 1 submitted in the present invention will be described in detail.

  Furthermore, as shown in FIG. 4, the cyclone separator 1 includes a cyclone cylinder 11, a cyclone separator end cover 12, a filter 13, and an air guide cylinder 14.

  Specifically, the upper end of the cyclone cylinder 11 is open, and the dust is contained in the bottom wall of the cyclone cylinder 11 so that the air containing the dust is separated into air, dust, etc. in the cyclone separator 1. A cyclone separator inlet 101 used to allow air to enter the cyclone cylinder 11 is provided. A cyclone separator end cover 12 provided with a cyclone separator outlet 102 is provided above the cyclone cylinder 11. Air containing dust is sucked into the cyclone separator 1 through the cyclone separator inlet 101, and then filtered through the cyclone separator 1. In the filtration process, dust and the like are separated and thrown out from the cyclone cylinder 11, but the filtered air is discharged through the cyclone separator outlet 102. The filter 13 filters air containing dust, and the gas passes through the filter 13 and is discharged from the cyclone separator 1. The upper end of the filter 13 is such that dust-containing air cannot pass through the cyclone separator outlet 102 and only the air filtered by the filter 13 passes through the cyclone separator outlet 102 and is discharged from the cyclone separator 1. Are communicated with the cyclone separator outlet 102, the upper end of the filter 13 closes the periphery of the cyclone separator outlet 102, and the lower end of the filter 13 is extended into the cyclone cylinder 11. The lower end of the air guide tube 14 is used for the cyclone separator so that the cyclone separator 1 is filtered and dust is thrown out from the cyclone tube 11 so that the airflow enters the cyclone tube 11 along the radial direction of the cyclone tube 11. While communicating with the inlet 101, the upper end of the air guide tube 14 is closed, and an air vent 103 communicating with the cyclone tube 11 is provided on the side wall of the air guide tube 14. As a result, air is introduced from the bottom and air containing dust that has entered the cyclone separator 1 enters the cyclone cylinder in a direction away from the filter 13. The dust containing dust that has entered the cyclone cylinder 11 is quickly turned into a spiral air flow, and dust is released from the filter 13 by the action of centrifugal force, and the dust is attached to the filter 13 by moving it away from the filter 13. Thus, clogging of the filter 13 can be avoided. With the cyclone separator according to the present invention, clogging of the filter 13 can be reduced, so that the usage time of the filter 13 can be extended and the frequency of cleaning the filter 13 can be reduced.

  Further, the air inlet 201 can easily communicate with the cyclone separator inlet 101.

  The upper end of the dust cup 2 is opened, and the upper end of the dust cup 2 is covered by a cyclone separator end cover 12.

  As shown in FIGS. 4 to 6, in some embodiments of the present invention, a wind guide plate 15 and a wind shield plate 16 are provided in the cyclone cylinder 11, and at least a part of the wind guide plate 15 faces upward. The wind shield plate 16 is provided above the ventilation port 103, and the height of the wind shield plate 16 is set to be equal to or less than the upper edge of the wind guide plate 15. That is, the airflow that has entered the cyclone cylinder 11 rises spirally along the extending direction of the air guide plate 15 by the action of the air guide plate 15 and the air shield plate 16. As a result, it is possible to adopt a wind guide structure in which the airflow rises in a spiral shape, and the position where the dust is thrown out is moved to the maximum to contain dust using the highly efficient cyclone separator 1. The airflow is accelerated by the air guide plate 15. After that, it is thrown out from the cyclone cylinder 11 so as to quickly and thoroughly separate dust and air, and strips such as hair and hair can be easily thrown out. As a result, the amount of dust and hair and hair discharged from the cyclone separator 1 through the filter 13 is reduced, and the suction force of the entire vacuum cleaner equipped with the cyclone separator 1 is quickly reduced due to clogging of the filtration net. It is possible to suppress the descent, greatly improve the separation efficiency, and extend the cleaning cycle of the filter screen.

  A person skilled in the art can understand that the air guide plate 15 and the wind shield plate 16 of the present invention are for spirally raising the airflow containing dust. Of course, in the present invention, the form that can be realized so that the airflow containing dust rises in a spiral shape is not limited to this, and other forms of wind guide structures in the prior art, for example, a spiral draft in a wind guide tube. It is also possible to form a path.

  Further, as shown in FIG. 5, the air guide plate 15 is annular, and includes a first plate body 151, a second plate body 152, a spiral air guide plate 153, and a connecting plate 154, The first plate 151 and the second plate 152 are each perpendicular to the axis of the cyclone cylinder 11, and the connecting plate 154 is parallel to the axis of the cyclone cylinder 11. That is, the first plate body 151 and the second plate body 152 are parallel to each other, and any one of the first plate body 151 and the second plate body 152 is perpendicular to the axis of the cyclone cylinder. Alternatively, as shown in FIG. 5, the first plate 151 and the second plate 152 are all perpendicular to the vertical direction shown in FIG. 5, and the connecting plate 154 is shown in the vertical direction shown in FIG. Parallel. The spiral wind guide plate 153 extends spirally along the vertical direction, that is, the spiral wind guide plate 153 extends spirally upward, but one end of the first plate body 151 is connected to the spiral wind guide plate 153. The other end of the first plate 151 is connected to the lower end of the connecting plate 154, the one end of the second plate 152 is connected to the upper end of the spiral air guide plate 153, and the first plate 151 is connected to the lower end. The other end of the two plate body 152 is connected to the upper end of the connecting plate 154.

It is flat and a connecting plate 154 is provided on the side edge of the vent 103. In other words, since the wind shield 16 is provided at the upper edge of the vent 103 and the connecting plate 154 is provided at the side edge of the vent 103, the wind shield 16 and the connecting plate 154 block the airflow. Acts. By causing the airflow to flow sequentially along the direction of the first plate body 151, the spiral air guide plate 153, and the second plate body 152, the airflow is raised spirally. In other words, the airflow entering the cyclone cylinder 11 from the vent 103 is blocked by using the air shield plate 16 and the connecting plate 154 so that the air containing dust does not rise directly, and the airflow containing dust is prevented. By elevating spirally along the direction of extension of the air guide plate 15, a spirally rising air flow is formed so that dust is thrown out by centrifugal force. As a result, the dust-containing airflow can easily rise in a spiral, and the airflow directly increases the filtration effect is bad, avoiding the filter becoming clogged, containing dust The separation efficiency and separation effect of the cyclone separator 1 with respect to the airflow can be improved. Further, by letting out dust and the like, the amount of dust and the like passing through the filter can be reduced.

  Preferably, the air guide plate 15 is the bottom wall of the cyclone cylinder 11 and the cyclone separator inlet 101 is formed in the air guide plate 15. In other words, the cyclone cylinder 11 includes a cylindrical side plate 111 and a wind guide plate 15, the wind guide plate 15 is provided in the cylindrical side plate 111, and the wind guide plate 15 is annular, and the annular wind guide plate The cyclone separator inlet 101 is formed in the middle portion of 15. As a result, the structure of the cyclone cylinder 11 is simplified by adopting the air guide plate 15 directly to form the bottom wall of the cyclone cylinder 11, making the formation of the cyclone cylinder 11 convenient, and the formability of the cyclone cylinder 11 Can be improved.

  The air guide plate 15 of the present invention may not be the bottom wall of the cyclone cylinder 11.

In other words, the filter 13 and the air guide tube 14 are integrally formed. Since the air guide tube 14 is formed integrally with the filter 13, the structure of the cyclone separator 1 can be simplified, and the productivity and the mountability of the cyclone separator 1 are improved.

  Of course, the air guide tube 14 and the filter 13 can be formed, respectively, and the filter 13 is located directly above the air guide tube 14.

  As shown in FIGS. 4 and 6, in one specific example of the present invention, the filter 13 and the cyclone separator end cover 12 are integrally formed. Thereby, the sealing function of the connection location of the filter 13 and the dust cup is improved, and the suction force of the vacuum cleaner having the cyclone separator is improved so as to improve the dust absorption efficiency.

  As shown in FIGS. 4 and 7, in some embodiments of the present invention, the upper edge of the cyclone cylinder 11 and the cyclone separator end cover 12 are spaced apart from each other. As a result, dust and other foreign matters separated in the cyclone cylinder 11 are discharged in all directions of 360 degrees, the position of the dust discharge is not limited, and the cyclone separator 1 with respect to the air flow containing dust The separation effect can be fully exhibited.

  Further, the filter 13 and the cyclone cylinder 11 are all cylindrical, and the center line of the cyclone cylinder 11 overlaps the center line of the air guide cylinder 14.

  As shown in FIG. 7, the height H1 of the air guide plate 15 is more than half of the depth H2 of the air guide tube 14, and the height H1 of the air guide plate 15 is less than the depth H2 of the air guide tube 14 It is. In other words, 0.5H2 ≦ H1 ≦ H2. Thereby, the wind guide effect of the cyclone cylinder 11 is improved, and the spiral rise of the airflow is facilitated.

  Further, the distance H3 between the end cover 12 for the cyclone separator and the upper edge of the cyclone cylinder 11 is not more than the height H1 of the air guide plate 15. As a result, dust and other foreign matters are easily thrown out, so that dust can be prevented from accumulating in the cyclone cylinder 11, and the accumulation of foreign matters such as dust in the dust cup is promoted.

  Preferably, the radius R1 of the filter 13 is not more than half of the radius R2 of the cyclone cylinder 11. In other words, the distance R3 along the radial direction between the cyclone cylinder 11 and the filter 13 is more than half of the radius R2 of the cyclone cylinder 11, and the distance R3 along the radial direction between the cyclone cylinder 11 and the filter 13 is The radius of the cyclone cylinder 11 is less than R2. In other words, the difference R3 between the radius of the cyclone cylinder 11 and the radius of the filter 13 is more than half of the radius R2 of the cyclone cylinder 11, and the difference between the radius of the cyclone cylinder 11 and the radius of the filter 13 The numerical value R3 is less than the radius R2 of the cyclone cylinder 11. That is, 0.5R2 ≦ R3 ≦ R2. Thereby, dust and other foreign matters are easily thrown out, and dust and other foreign matters are adsorbed by the filter 13 to prevent the filter 13 from being clogged, and the dust passes through the filter 13. Avoid increasing the frequency of dust removal in the filter screen.

  Therefore, the cyclone separator according to the present invention can improve the separation efficiency of the airflow containing dust.

  As shown in FIGS. 1 to 7, in one specific embodiment of the present invention, the present invention provides a new cyclone separator 1 to achieve high sealing performance and high suction force of the cyclone separator 1. At the same time, low cost can be realized.

  Specifically, the cyclone separator 1 includes a cyclone cylinder 11, a filter 13 located in the center of the cyclone cylinder 11, and a cyclone separator end cover 12 located above the filter 13, and the cyclone separator end There is a gap between the cover 12 and the upper edge of the cyclone cylinder 11, and an inlet pipe 17 is connected to the center position of the bottom of the cyclone cylinder 11, so that dust-containing gas passes through the inlet pipe 17. After entering the cyclone cylinder 11, it is accelerated and rotated through the air guide plate 15 inside. A wind guide plate 15 is located between the inlet pipe 17 and the filter 13.

  Since there is an air intake structure below the center of the cyclone separator 1, the loss of power is reduced, and the position where dust is thrown out is moved upward as much as possible, using a highly efficient cyclone separator, Dust-containing airflow is accelerated and raised by a spiral line and released freely in all directions of 360 degrees. It is not limited to the position where dust is thrown out, the separation is more thorough, and strips such as hair and hair can be easily thrown out. In addition, the separation efficiency can be greatly improved and the number of cleanings of the filter screen can be extended.

  The cyclone separator end cover 12 and the filter 13 may be integrally formed, or may be assembled after forming a plurality of parts. The air inlet pipe 17, the air guide plate 15, and the cyclone cylinder 11 may be integrally formed, or may be assembled after a plurality of parts are formed. The filter 13, the cyclone separator end cover 12, and the inlet pipe 17 may be integrally formed, or may be assembled after forming a plurality of parts. The air guide plate 15 and the cyclone cylinder 11 may be integrally formed, or may be assembled after a plurality of parts are formed. These can be understood by those skilled in the art.

  Since the lower side of the center of the dust collector 100 has an air inlet structure, the length of the air inlet pipe 17 can be greatly shortened to reduce power loss, and dust can be released freely in all directions of 360 degrees. Is possible. Moreover, it is not restricted to the position where dust is thrown out, and separation can be performed more thoroughly, and it is also possible to easily throw out strips such as hair and hair. Therefore, the suction force of the entire cleaner is not lowered at an early stage due to clogging of the filter screen, so that the separation efficiency can be greatly improved and the number of times of cleaning the filter screen can be extended.

  Since the vacuum cleaner according to the embodiment of the present invention has a new air passage structure, it realizes a large suction force and low noise, is small and light, and is easy to assemble. That is, the air passage of the dust collection and separation system is simple, short and highly efficient, the silencer air passage is bent and long, and there is no stagnation.

  The structure adopts a cyclone separation structure where the air enters from the center, and after the dust-containing air passes through a short introduction passage, it directly enters the high-efficiency separation chamber of the dust cup and quickly removes dust and air. To separate. After the secondary filtration of the filter screen, the airflow enters the silenced air passage system, that is, the airflow stabilization chamber, from the side wall of the upper lid of the dust cup, flows into the motor, and flows from the motor outlet to the motor inner cover. After that, the sound is silenced through a small hole in the motor inner cover, flows into the rotating chamber of the motor outer cover, enters the passage formed in the motor outer cover and the casing through the passage between the motor inner cover and the outer cover. Then, after being silenced by the blast sponge, it returns to the outside air.

  In terms of cost, in the dust collecting air passage portion of this form, since the conventional side inlet air duct is omitted, the material cost and the manpower cost can be reduced. From the viewpoint of function, the air passage is short and there is no stagnation, so there is very little power loss, including the action of the flow-induced air passage of the highly efficient separation chamber, and the separation of dust and air is more thorough. Become.
