However, among the vacuum cleaners described in Patent Document 1, in the former vacuum cleaner in which the motor is disposed in the dust collection chamber, the power cord (winding reel) is disposed in the rear chamber. Wiring is performed through the partition wall, and the wiring distance becomes long. Further, the wiring via the partition wall has a problem that the airtightness with respect to the rear chamber of the dust collection chamber may be lowered, and the manufacturing process of the vacuum cleaner becomes complicated.
On the other hand, in the latter vacuum cleaner in which the motor is disposed in the small chamber, since the motor is disposed in the vicinity of the partition wall, the wiring distance from the power cord is shorter than that in the former vacuum cleaner. However, in the latter vacuum cleaner, since the wiring is applied to the motor in the small chamber separated from the rear chamber, the problem that the manufacturing process of the vacuum cleaner becomes complicated is not solved.
Further, in the latter vacuum cleaner, the motor is arranged below the electric blower, and the arrangement position of the electric blower is shifted upward by the arrangement space of the motor. Therefore, the height of the vacuum cleaner increases. In the latter vacuum cleaner, a small chamber in which the motor is disposed is necessary. Therefore, the thickness of the wall of the small chamber further increases the height of the vacuum cleaner.

Therefore, it is conceivable to arrange the motor in the rear chamber together with the electric blower. However, even if the space for the motor is secured in the rear chamber, the height, width, and length of the vacuum cleaner can be increased by shifting the position of the electric blower to either the top, bottom, left, or back in the case. Will increase.
Therefore, it is desirable to provide a vacuum cleaner that can be easily wired to a motor that drives the dust removal device and that can be made compact by effectively using the space in the case as compared with a conventional vacuum cleaner. It was.

  Therefore, the problem of the present invention is that, compared to a conventional vacuum cleaner, wiring to a motor for driving the dust removing device is easy, and the space in the case can be effectively used to achieve compactness. It is to provide a vacuum cleaner.

The present invention that solves the above-mentioned problems includes a dust collection chamber that is formed in a case and in which a dust bag is disposed, and a power cord disposed in a reel chamber that is formed in the case adjacent to the dust collection chamber. A vacuum cleaner comprising: a take-up reel; a dust removing device disposed in the dust collecting chamber and driven to drop dust attached to the inner surface of the dust collecting bag; and a motor for driving the dust removing device.

To do.
In this electric vacuum cleaner, since the motor is disposed in the reel chamber, the motor is closer to the take-up reel of the power cord than the conventional electric vacuum cleaner, so that wiring to the motor is facilitated.
In this vacuum cleaner, the motor is arranged in the reel chamber so that it does not interfere with the winding of the power cord on the take-up reel, and the rotating shaft of the motor is more dust collecting than the rotating shaft of the take-up reel. Since the motor is arranged on the upper side or the lower side of the chamber side, that is, in the dead space of the reel chamber, the space in the case is effectively used compared to the conventional vacuum cleaner.

  According to the vacuum cleaner of the present invention, the wiring to the motor for driving the dust removing device becomes easier as compared with the conventional vacuum cleaner, so that the manufacturing process is simplified and the space in the case is reduced. Since it can be used effectively, the vacuum cleaner can be made compact.

A dust removal spring 23 is spirally wound around the circumferential surface of the dust removal rotating body 21. The dust removal spring 23 rotates together with the dust removal rotating body 21.

  As shown in FIG. 6B, the contour shape of the dust removal spring 23 viewed from the direction in which the rotation axis A3 of the dust removal rotating body 21 extends is a hexagon. The outline shape of the dust removal spring 23 is not limited to a hexagonal shape, and any protrusion 23a that partially protrudes from the peripheral surface side of the dust removal rotating body 21 toward the radially outer side may be formed. Other polygonal shapes or elliptical shapes may be used.

  As shown in FIG. 2, when the dust removal unit 2 is fitted into the recess 12 a of the lower case 12, the circumferential surface of the dust removal rotating body 21 faces the dust collection chamber 8 and the protruding portion 23 a of the dust removal spring 23. (Refer to FIG. 6B) comes into contact with the lower end side of the first dust removing member 31 (see FIG. 7) constituting the dust removing device 3 described later.

  In addition, as shown in FIG. 2, when the dust removal unit 2 is fitted in the recess 12a, the dust collection chamber 8 and the reel chamber 9b are airtightly separated, and the dust collection chamber 8 and the outside of the lower case 12 are separated from each other. As shown in FIG. 6A, a gasket 25 is attached to the support member 22 at a portion that contacts the recess 12 a of the lower case 12.

  As shown in FIG. 7, the dust removing device 3 includes a first dust removing member 31, a second dust removing member 32, a power branch member 34, and a third dust removing member 33.

  The first dust removing member 31 is a substantially rectangular plate-like lattice body, and is disposed along the partition wall 14 on the dust collection chamber 8 (see FIG. 1) side. The first dust removing member 31 is pivotally supported by ribs 14b erected on the partition wall 14 at both ends on the upper edge side, and is rotatable around the shaft portion 14c. That is, the first dust removing member 31 is movable in the direction away from the partition wall 14 on the lower edge side with the shaft portion 14 c as a fulcrum.

  The second dust removing member 32 is a substantially rectangular plate-like slit body, and its rear edge is locked to the lower edge of the first dust removing member 31 so that the first dust removing member 31 is, for example, 90 degrees. It attaches to the 1st dust removal member 31 so that a predetermined angle may be made.

  The power branch member 34 is a rod-shaped body, and is disposed between the partition wall 14 and the first dust removing member 31 and attached to the partition wall 14 so as to be slidable in the vertical direction. The upper end 34a of the power branch member 34 is in contact with the input part 33c of the third dust removing member. As will be described later, the lower end 34b (see FIG. 9B) is a dust removing unit. 2 cam 24 (see FIG. 9B).

  As described above, the third dust removing member 33 is disposed inside the opening / closing lid 11a (see FIG. 1), and as shown in FIG. 8, a main body member 33a formed of a substantially horseshoe-shaped plate-like slit body, And a plate-like auxiliary member 33b attached to the left and right sides of the main body member 33a via a support shaft 33d. The main body member 33a includes a plate-like input portion 33c formed so as to protrude rearward from the rear end side. The main body member 33a includes shaft portions 33e on both sides of the rear end. The main body member 33a is pivotally supported by the opening / closing lid 11a via the shaft portion 33e. That is, when a load is input to the input portion 33c in the front and back direction of the opening / closing lid 11a, the main body member 33a and the auxiliary member 33b can swing around the shaft portion 33e.

  As shown in FIG. 9A, such a dust removing device 3 has a protrusion 23a of the dust removing spring 23 when the dust removing rotary body 21 and the dust removing spring 23 of the dust removing unit 2 are rotated by the motor 5 (see FIG. 4). (Refer to FIG. 6B) intermittently contacts the lower end side of the first dust removing member 31. As a result, the first dust removing member 31 intermittently presses the dust collection bag 7 by rotating around the shaft portion 14c. That is, the first dust removing member 31 gives vibration to the dust collection bag 7. At this time, since the second dust removing member 32 is attached to the first dust removing member 31 so as to be at the predetermined angle, the second dust removing member 32 rotates around the shaft portion 14c as shown in FIG. By doing so, vibration is given to the dust bag 7 together with the first dust removing member 31 from below.

  Further, as shown in FIG. 9B, when the dust removal rotating body 21 of the dust removal unit 2 is rotated by the motor 5 (see FIG. 4), the cam 24 intermittently contacts the lower end portion 34 b of the power branch member 34. . As a result, the power branch member 34 reciprocates in the vertical direction, so that the upper end portion 34 a intermittently presses the input portion 33 c of the third dust removing member 33. As a result, the third dust removing member 33 intermittently presses the dust collection bag 7 by rotating around the shaft portion 33e. For this reason, the 3rd dust removal member 33 gives a vibration to the dust bag 7 from the upper side.

  That is, in the dust removing device 3, the rotation of the motor 5 (see FIG. 4) is such that the motor side gear G1 (see FIG. 4), the unit side gear G2 of the dust removing unit 2 (see FIG. 4), and the dust removing rotating body 21 (see FIG. 4). 9 (a) and (b)), the dust bag 7 is vibrated to drop the dust attached to the inner surface of the dust bag 7.

Next, the effect of the vacuum cleaner C which concerns on this embodiment is demonstrated.
In this vacuum cleaner C, since the motor 5 is disposed in the reel chamber 9b, the motor 5 is closer to the take-up reel 4 of the power cord 4a than in the conventional vacuum cleaner (see, for example, Patent Document 1). Therefore, the wiring distance to the motor 5 is shortened. Further, unlike the conventional vacuum cleaner (see, for example, Patent Document 1), it is not necessary to provide wiring to the motor 5 via the partition wall 14, so that the airtightness with respect to the rear chamber 9 of the dust collection chamber 8 is reduced. The fear of causing it is avoided. Therefore, according to this vacuum cleaner C, the manufacturing process of the vacuum cleaner C becomes easier.

  Further, in this vacuum cleaner C, the dust removal unit 2 is not equipped with parts that require electricity supply, for example, the motor 5 or the like. Therefore, when the dust removal unit 2 is fitted into the recess 12 a formed at the bottom of the case 1. There is no need to wire the dust removal unit 2. Therefore, according to this vacuum cleaner C, the structure of the dust removal unit 2 can be simplified.

  Further, in this electric vacuum cleaner C, the motor 5 is disposed in the reel chamber 9b so as not to interfere with the winding of the power cord 4a onto the take-up reel 4, and the rotating shaft A2 of the motor 5 is provided with the take-up reel. Since the motor 5 is disposed closer to the lower side of the dust collection chamber 8 than the rotation axis A1 of 4, that is, in the dead space of the reel chamber 9b, the space in the case 1 is effectively used compared with the conventional vacuum cleaner. Is done. As a result, the height, width, and length of the vacuum cleaner C are not increased, and the vacuum cleaner C can be made compact.

  Further, the vacuum cleaner C is configured such that the driving force of the motor 5 is transmitted to the dust removing device 3 by fitting the dust removing unit 2 into the recess 12 a formed in the bottom of the case 1. As a result, in this vacuum cleaner C, unlike the conventional vacuum cleaner (see, for example, Patent Document 1), the step of assembling the connecting shaft directly in the case to connect the motor and the dust removing device is omitted. Is done. Moreover, since the member which transmits the drive force of the motor 5 to the dust removal apparatus 3 is integrated as the dust removal unit 2, the assembly becomes easy compared with what attaches these members separately. Therefore, according to this electric vacuum cleaner C, the manufacturing process becomes easier. Further, since the dust removal unit 2 is attached from the outside of the case 1, it is easy to replace the member that transmits the driving force of the motor 5 to the dust removal device 3.

  Moreover, in this vacuum cleaner C, since the rotation center of the motor side gear G1 is located above the rotation center of the unit side gear G2, the dust removing unit 2 is attached to the recess 12a formed at the bottom of the case 1. When fitted, the unit side gear G2 can be easily engaged with the motor side gear G1.

  Further, in this electric vacuum cleaner C, the motor side gear G1 and the unit side gear G2 mesh with each other in the reel chamber 9b, so that the motor side gear G1 and the unit side gear G2 mesh with each other in the dust collection chamber 8. Thus, this engagement is not hindered by the dust bag 7 swelled in the dust chamber 8.

  Moreover, in this electric vacuum cleaner C, since the motor 5 is attached to this bending part 14a, at least one part of the motor 5 can be accommodated in the bending part 14a. As a result, according to the vacuum cleaner C, the length of the reel chamber 9b can be shortened, so that the vacuum cleaner C can be made compact.

In addition, this invention is implemented in various forms, without being limited to the said embodiment.
In the above embodiment, the rotation axis A2 of the motor 5 is arranged to be closer to the lower side than the rotation axis A1 of the take-up reel 4. However, in the present invention, the rotation axis A2 of the motor 5 is the take-up reel 4. It may be arranged so as to be closer to the upper side than the rotation axis A1. In such a vacuum cleaner C, since the motor 5 is disposed in the dead space of the reel chamber 9b as in the case of the vacuum cleaner C according to the above-described embodiment, the inside of the case 1 is compared with the conventional vacuum cleaner. Space is effectively utilized. As a result, the height, width, and length of the vacuum cleaner C are not increased, and the vacuum cleaner C can be made compact. Further, in the vacuum cleaner C in which the motor 5 is arranged on the upper side, the dust removing unit 2 is attached to the upper case 11 side, and the driving force of the motor 5 is transmitted by such a dust removing unit 2. 3 is configured.
