At this time, the microcomputer 69 is configured to more effectively control the respective suction motors (54A, 54B). Hereinafter, although the first suction motor, the next suction motor, the suction motor in operation, the last suction motor, etc. are specified as the suction motor 54A or the suction motor 54B, this describes the operation state of the microcomputer 69. It is for the purpose of, but not limited to.

This will be described in more detail as follows. The microcomputer 69 is supplied with power from the main switch 62, the automatic selection switch 64A is 'on', and the rotary operation switch 37 is 'on'. ', The operation time of each suction motor 54A, 54B is searched and the power is supplied only for the set time to the selected first suction motor 54A, and when the set time elapses, the power of the first suction motor 54A is At the same time, the power is applied only to the next suction motor 54B, and when the set time elapses, the process of shutting off the power applied to the next suction motor 54B is repeatedly repeated.

If one of the main switch 62 or the rotary operation switch 37 is 'off' in such a state that the process is repeatedly performed, at the same time the power applied to the suction motor 54A or 54B is being cut off, When the remaining time is stored at the 'off' time, and the main switch 62 is 'on', and the rotary operation switch 37 is 'on', the remaining time of the last operated suction motor 54A is searched for the final time. The power is supplied to the operated suction motor 54A only for the remaining time, and the last operated suction motor 54A operates for the remaining time to cut off the applied power when the set time elapses, and the next suction motor 54B. When the power is applied only for the time set in, and the set time elapses, the power is applied to the next suction motor 54B and the power is supplied only for the time set in the next suction motor 54A. Continuous repeated .

On the other hand, when the manual selection switch 64B is 'on' while the power is supplied, and the rotary operation switch 37 is 'on', power is applied to the respective suction motors 54A and 54B. When either the main switch 62 or the rotary operation switch 37 is 'off', it is configured to cut off the power applied to each of the suction motors 54A and 54B.

The microcomputer 69 controls the drive unit 60 to efficiently use the respective suction motors 54A and 54B to extend the life thereof and to generate a strong suction force.

Referring to the operation of the present invention configured as described above in detail based on the accompanying drawings as follows.

As shown in FIG. 3 or 7, when the main switch 62 is 'on', external power is supplied to the control means 60 to be in the control standby state (S101) In this state, the user The operation time of each suction motor 54A, 54B is input to the time setting switch 66. (S102) For example, if the operation time of each suction motor 54A, 54B is inputted for 5 minutes, The microcomputer 69 stores this and recognizes the time as an operation time until the operation time is re-entered or reset. In addition, the automatic / manual selection switches 64A and 64B are used to select each of the suction motors 54A and 54B alternately or simultaneously. (S103) If the consumer selects the automatic selection switch 64A. If is selected, the microcomputer 69 receives the signal and stores it.

As described above, the operation time of each of the suction motors 54A and 54B is input, and a signal is input from the automatic selection switch 64A. The suction hose 22 is used for cleaning using the suction hose 22. ) Pulled downward (forward), the tow bar 35 is rotated in the direction of the arrow (down) shown by a dashed line in Figure 2 with respect to the rotating rod 33, at this time, the rotary operation switch ( 37 is operated 'on' by interfering with the pull rod 35 that rotates downward (S104), the microcomputer 69 receives the signal.

At this time, the suction hose 22 towed by the tow bar 35 is prevented from being bent because the middle portion thereof is coupled to the bend prevention member 36 as shown in FIG. 2.

On the other hand, when the microcomputer 69 receives the 'on' signal from the rotary operation switch 37 by the operation of the tow bar 35, the first suction selected by searching the operating time of each suction motor (54A, 54B) The power is supplied to the motor 54A only for the time initially set to be operated. (S105, S106)

When power is applied to the first suction motor 54A, the suction force is generated by the suction motor 54A that is operated.

The suction force generated by the suction motor 54A is generated in the direction of the arrow A shown in FIG. 4 to pass foreign substances contained in the external air through the filtering means 20, and then filtered and separated from the external air. Pass through the hood member 40 and the exhaust hose 52 is discharged through the drive unit (60).

At this time, the external air passing through the hood member 40 is first connected to the suction motor 54A and the first compartment 42 to the exhaust hose 52, so that the suction force is the first compartment 42 ) Acts on the main compartment 41 and is discharged through the main compartment 41 and the first compartment 42, wherein the first opening / closing member 44 closing the first through hole 42A is discharged. The suction force generated by the suction motor 54A acts on the first compartment 42, thereby opening the first through hole 42A.

That is, since the suction force generated by the suction motor 54A acts on the first compartment 42, the first opening / closing member 44 is moved to the exhaust hose 52 side by the suction force, and the first The through hole 42A is opened so that the main compartment 41 is in a vacuum state, and in the second compartment 43, a suction force acts on the main compartment 41, so that the second opening / closing member 45 is opened. The second through hole 43A is to be closed.

If the next suction motor 54B is operated, the above operation is reversed.

As described above, a process in which foreign matter sucked by the operation of the first suction motor 54A is filtered by the filtration means 20 is as follows.

The suction force generated by the suction motor 54A strongly introduces external air containing foreign substances into the primary dust collecting member 24. In this way, foreign matter introduced into the suction hole 24C through the suction hose 22 together with the external air hits the outer circumferential surface of the secondary dust collecting member 26.

As described above, foreign matters introduced into the suction hole 24C and hit the outer circumferential surface of the secondary dust collecting member 26 facing the suction hole 24C lose their thrust and fall downward to be separated first, and at the same time, the remaining foreign matter is separated. It rotates while forming the vortex in the direction of arrow B shown in FIG. 4 together with the external air, so that the suction hole 24C does not coincide with the center line virtually extending from the center of the installation hole 24A. This is because it is formed only slightly (so that the center line of each other does not coincide), the foreign matter and the external air hit the outer peripheral surface of the secondary dust collecting member 26 does not rotate in the direction of the arrow (C) shown in FIG. will be.

On the other hand, some of the external air and foreign matter introduced into the suction hole (24C) is rotated in the direction of the arrow (B) by the vortex formed by the suction force, the plurality of inflow formed in the secondary dust collecting member 26 up and down It flows into the ball 26A.

That is, since the inflow hole 26A is formed to maintain a constant angle θ with the intake hole 24C, only a part of the foreign matter rotating by the vortex deflects its moving direction toward the inflow hole 26A. It is coming in. In other words, the foreign matter rotated by the vortex is moved to the inner wall side of the primary dust collecting member 24 by centrifugal force, but a part of the dried fine foreign matter is applied to the suction force acting inside the secondary dust collecting member 26. By changing the direction of movement.

At this time, a relatively large foreign material such as a piece of toilet paper, cigarette butts, toothpicks, paper pieces, coins, etc., among the foreign substances introduced into the suction hole 24C may be disposed on the top plate (24C) side of the suction hole 24C of the primary dust collecting member 24. A plurality of separation rods 24D installed downward on the 24B) hit or hang and fall downward. That is, since each of the separating rods 24D is installed vertically with different intervals in the shape of arcs, foreign substances introduced into the separating rods 24D are not moved in the direction of the arrow B by being caught by the separating rods 24D. If the foreign matter moved in the direction of the arrow (A) is to fall back to hit each of the separating rods (24D) without rotating rotation. In addition, the process of rotating while moving to the inner wall side of the primary dust collecting member 24 is rotated in the direction of the arrow (B) together with the external air by the centrifugal force of the vortex, except for a relatively large foreign matter or dust containing moisture or oil Falling downward by its own weight, only a part of the dried fine dust and the outside air is introduced into the inlet hole (26A) of the secondary dust collecting member (26).

Therefore, the large and small foreign matters or moisture or oil-containing dust is separated from the outside air through the process of separating by the vortex in the primary dust collecting member 24, and then falls downward, and in this process Since only a part of the fine foreign matter is introduced into the secondary dust collecting member 26, the dried fine dust introduced into the secondary dust collecting member 26 affects the suction force of each of the suction motors 54A and 54B. Will not give. That is, some of the fine foreign matter adsorbed on the bag filter 26B of the secondary dust collecting member 26 is changed to a part of the filter layer so as not to affect the suction force.

As such, external air containing foreign matter introduced into the secondary dust collecting member 26 is finally filtered by the bag filter 26B installed therein and then discharged to the open upper portion.

On the other hand, the outside air through which the foreign matter is filtered through the secondary dust collecting member 26 flows into the main compartment 41 of the hood member 40, the outside air introduced into the main compartment 41 is exhausted. It enters into the 1st compartment 42 connected with the suction motor 54A which was first operated by the hose 52. As shown in FIG.

That is, since the suction force generated by the operation of the first operated suction motor 54A acts on the first compartment 42, the first opening / closing member 44 closing the first through hole 42A is The first through hole 42A is opened while being rotated toward the exhaust hose 52, and thus suction force is generated in the main compartment 41 toward the first compartment 42. At this time, since the main compartment 41 is in a vacuum state, the second opening / closing member 45 is in close contact with the second through hole 42A in the main compartment 41 to close the place.

Accordingly, the external air passing through the secondary dust collecting member 26 is discharged to the exhaust hose 52 through the main compartment 41 and the first compartment 42 as shown in FIG. 5A.

On the other hand, the microcomputer 69 of the control means 60, when the set operating time of the first suction motor 54A has elapsed (S107) and at the same time cut off the applied power (S108) to the next suction motor 54B. Operate by applying power (S109).

When the next suction motor 54B is operated, the suction force generated thereby acts on the second compartment 43, and when the suction force acts on the second compartment 43, the second opening / closing member 45 sucks. By opening the second through hole (43A), on the contrary, the first opening and closing member 44 closes the first through hole (43A), and thus suction force also acts on the main compartment (41) The external air passing through the secondary dust collecting member 26 is discharged through the second compartment 43.

In this state, when the operation time of the next suction motor 54B elapses (S110), the microcomputer 69 cuts off the power applied to the next suction motor 54B, and (S111) again the first suction motor 54A. ) (The next suction motor in the case of multiple suction motors) is repeatedly performed. In the present embodiment, two suction motors 54A and 54B and two compartments 42 and 43 have been described, but the present invention is not limited thereto, and may be further used.

As described above, in a state in which the first operated suction motor 54A and the next operated suction motor 54B are alternately operated repeatedly (S111A), the user 'offs' or uses the main switch 62. When the suction hose 22 is released and the rotary operation switch 37 is 'off' (S112), the microcomputer 69 cuts off the power applied to the suction motor 54A or 54B which is being operated and at the same time 'off'. 'Stores the time remaining in the set time of the suction motor 54A or 54B that was in operation at the time when the signal was generated. (S113) For example, the operation set time of the suction motor 54A in operation was 5 minutes. If the 'off' time has elapsed three minutes, the microcomputer 69 stores the remaining two minutes, in association with the suction motor 54A that was in operation.

At this time, the process of turning off the rotary operation switch 37 is as follows. That is, since the suction hose 22 used by the user is in the state of receiving the elastic force of the vertical rotating plate 34, when the suction hose 22 is released, the suction hose 22 is elastic to the hydraulic means. The tow bar 35 is towed to rotate to move upwards, thereby turning the rotary operation switch 37 while the tow bar 35 is rotated.

As described above, when any one of the main switch 62 or the rotary operation switch 37 is 'off', the microcomputer 69 storing the remaining time of the suction motor 54A which is in operation is the main switch ( When 62 is 'ON' and the rotary operation switch 37 is 'ON' by use of the suction hose 22 (S114), the Suction motor 54A which is finally operated is searched (S115). Search and check the remaining time corresponding to the motor 54A (S116, S117) and apply power only for the remaining time (S118), and when the time elapses (S119), set time to the next suction motor 54B While the main switch 62 or the rotary operation switch 37 is controlled to be repeatedly performed until a time when the main switch 62 or the rotary operation switch 37 is 'off'.

On the other hand, when the user needs a strong suction force, the microcomputer 69 controls the suction motors 54A and 54B as follows.

That is, when the user uses the suction hose 22 while the manual selection switch 64B is 'on', the rotary operation switch 37 is 'on'.

When the manual selection switch 64B is 'on' and the rotary operation switch 37 is turned on, the microcomputer 69 simultaneously applies power to each of the suction motors 54A and 54B.

In this case, the microcomputer 69 may be configured not only to apply the suction motors 54A and 54B for a set time as described above, but also the rotary operation switch 37 and the suction motors 54A and 54B. ) Directly connects the power supply via the main switch 62 to the respective suction motors 54A and 54B by the 'on' operation of the rotary operation switch 37, thereby allowing the respective suction motors 54A, 54B) can prevent the microcomputer 69 from being controlled.

The suction force generated by applying power to the suction motors 54A and 54B at the same time acts on the first and second compartments 42 and 43 at the same time. The second through holes 42A and 42B are opened at the same time, and thus the external air passing through the secondary dust collecting member 26 is discharged through the first and second compartments 42 and 43.

As the plurality of suction motors 54A and 54B are operated at the same time, the suction force can be doubled. As a result, the vortices generated inside the primary dust collecting member 24 are more powerfully generated to easily separate various foreign substances. It can be done.

On the other hand, the outside air passing through the hood member 40 has a noise reduction function installed on the case side of the suction motors 54A and 54B by the suction motors 54A and 54B through the exhaust hose 52. It is discharged to the atmosphere through the final filtering member.

When the rotary operation switch 37 is 'off' by the main switch 62 or the user releasing the suction hose 22 while the suction motors 54A and 54B are operating as described above, (S122). The microcomputer 69 stops the power applied to each of the suction motors 54A and 54B to stop each of the suction motors 54A and 54B. (S123) At this time, each of the suction motors 54A and 54B When the operation time is set, each of the suction motors 54A and 54B may be automatically stopped when the set time has elapsed.

In the vacuum cleaner according to the present invention, a relatively large foreign material such as a toilet paper, a piece of plastic, a toothpick, a piece of paper, a coin, and the like, and the fine dust containing moisture or oil are separated by the vortex generated by the suction force in the primary dust collecting member. It is possible to prevent clogging due to fine dust containing foreign substances and moisture, and by installing the middle portion of the suction hose in the bending prevention member, the bending can be prevented, and the suction hose is moved to the left and right by the traction means. It can be rotated and moved, so that it is easy to use, and it is possible to extend the life of the suction motor by operating a plurality of suction motors simultaneously or alternately, and on / off switch installed in the traction means when the suction hose is completed. By the suction motor is configured to automatically stop by, it is possible to prevent the continuous operation of the suction motor by 'off' oblivion The useful effect is provided, and a transparent confirmation window is formed on the primary dust collecting member of the filtration means, so that the consumer can visually check the process of separating and filtering foreign substances, thereby making it reliable for the vacuum cleaner according to the present invention.
