Description

  The present invention relates to a vacuum cleaner.

  FIG. 13 shows an external appearance of a conventional vacuum cleaner. The electric vacuum cleaner 101 includes a vacuum cleaner main body 102 and a hose 103. When a cleaning operation is performed in the electric vacuum cleaner 101, an air flow 41 containing dust flows into the cleaner main body 102 via the hose 103 as shown in FIG. 14. The vacuum cleaner 101 is assumed to be a cyclone system as an example. Since the vacuum cleaner 101 is of a cyclone type, the air flow 41 is guided to the cyclone separation unit 104 and becomes a rotational flow 42 in the cyclone separation unit 104, and the dust 51 is separated by the centrifugal force of the rotational flow 42, and is collected below. The dust case 105 is configured to collect and collect dust. The air flow after separating the dust 51 exits the cyclone separation unit 104 and passes through the filter unit 106 as air flows 43 and 44.

  The airflows 43 and 44 contain dust that could not be collected by the cyclone separation unit 104, but most of the dust is collected by a filter installed in the filter unit 106. That is, it adheres to the upstream surface of the filter.

  When dust accumulates on the filter, it is necessary to clean the filter. This cleaning operation is usually necessary if it is a vacuum cleaner provided with a filter not only in a cyclone type vacuum cleaner but also in other types of vacuum cleaners. A filter dust removal mechanism has already been put to practical use so that this cleaning operation can be easily performed. An example is shown in FIG.

  FIG. 15 shows the filter unit 106 viewed from the downstream side. The filter unit 106 includes a filter 115 and a filter dust removal mechanism 161. The filter dust removing mechanism 161 includes a rail 165 and a movable body 166 that can move in parallel along the rail 165. The rail 165 is fixed to the filter frame 116 so as to cross the exposed portion of the filter 115. The moving body 166 includes a knob 166a that projects forward. The user can move the moving body 166 left and right by hooking his / her finger on the knob 166a. A vibration generating protrusion (not shown) that protrudes toward the filter 115 is provided on the back side of the moving body 166. The vibration generating protrusion protrudes at a height that contacts the filter 115. When the moving body 166 moves along the rail 165, the vibration generating protrusion repeatedly collides with the tops of the plurality of mountain shapes of the filter 115. In other words, the vibration generating protrusion scratches the surface of the filter 115. Due to this scratching operation, vibration is generated in the filter 115. Most of the dust adhering to the filter 115 is adhering to the upstream side, that is, the back side in FIG. Therefore, in order to clean the filter 115, the user may move the moving body 166 while holding the filter unit 106. By doing so, the dust adhering to the filter 115 falls off from the filter 115.

  If the vacuum cleaner includes such a filter dust removing mechanism in the filter unit, the user can quickly clean the filter with a simple operation without getting his hands dirty.

  Several other techniques have been proposed for the filter dust removal mechanism. For example, in Japanese Patent Application Laid-Open No. 2004-358031 (Patent Document 1), dust is removed by a member piece colliding with each pleat-shaped peak portion of a filter in conjunction with an operation of taking out the dust collecting portion from the main body. The configuration is described. Further, Patent Document 1 discloses that a filter is also used in which dust is removed by manually sliding the knob after the dust collecting unit is taken out.

JP 2004-358031 A

  In the filter dust removing mechanism 161 (see FIG. 15) described above, the moving body 166 provided with the vibration generating projections only moves along the rail 165, so that it is close to the rail 165 in the entire region where the filter 115 is stretched. In the portion, a sufficiently strong vibration is generated with a large amplitude, but only a small vibration having a small amplitude is generated in a portion far from the rail 165. Since this vibration bias is determined by the position of the rail 165, the part of the filter 115 that vibrates frequently vibrates well and dust removal is ensured, but the part that does not vibrate so much does not always vibrate. The state where dust removal is not sufficient continues fixedly. Therefore, the accumulated dust has not been sufficiently removed in a part of the filter area.

  This problem also exists in the mechanism described in Patent Document 1.

  Therefore, an object of the present invention is to provide a vacuum cleaner, a filter with a dust removal mechanism, and a filter dust removal mechanism capable of generating sufficient vibration for dust removal over the entire region of the filter as much as possible.

The vacuum cleaner based on this invention collects the dust contained after the air blower for producing | generating a suction wind, the main-body part which accommodates the said air blower, the separation part which isolate | separates the dust contained in the said suction air, and separation A filter for removing the dust adhering to the upstream side of the suction air of the filter,

A dust removing container for storing the dust removed by the filter dust removing mechanism separately from the separation container;
The filter, the separation housing portion and the dust removal housing portion are integrated, and a take-out portion provided detachably from the main body portion is provided.

  Moreover, the said extraction part is the vacuum cleaner which enabled it to discharge | emit the dust collected by the said separation | accommodation accommodating part and dust removal accommodating part by taking out from the said main-body part.

  In addition, the air flow exiting the separation part from which dust has been separated is passed through the filter integrated with the extraction part and exhausted to the rear side containing the blower. Moreover, the said separation | accommodation accommodating part and dust removal accommodating part are equipped with the opening part in the lower end, the lid | cover which can be opened and closed which closes this whole opening part, and the latching | locking part which makes this lid | cover close. The lid has a portion for storing the separated dust and a portion for storing the dust separated from the filter by the filter dust removing mechanism, and releasing the locking portion to open the closed opening. , Each dust is discharged together.

  According to the present invention, the dust collected by the filter is separated by the filter dust removal mechanism, and the dust and the separated dust are separated and accommodated, and separated by removing the filter. Can be discharged together with dust.

(Embodiment 1)
(Constitution)
With reference to FIGS. 1-10, the vacuum cleaner in Embodiment 1 based on this invention is demonstrated. As shown in FIG. 1, the electric vacuum cleaner 1 is a cyclone type electric vacuum cleaner, and includes a cleaner main body 2 and a hose 3. The vacuum cleaner main body 2 is provided with a main body upper lid 2a that can be opened and closed. FIG. 2 shows a state in which the main body upper lid 2a is opened. In FIG. 2, the hose 3 is removed. As shown in FIG. 2, when the main body upper lid 2 a is opened, the take-out portion 10 housed in the cleaner body 2 is exposed. In particular, the handle 11 provided on the upper side of the take-out portion 10 is exposed. The handle 11 is urged upward by an elastic body housed therein, that is, upward, and is pushed downward by the main body upper cover 2a when the main body upper cover 2a is closed. By opening, it protrudes upward by the force of the elastic body. The user can hold the handle 11 and pull out the take-out portion 10 from the cleaner body 2.

  The taken-out extraction part 10 is shown in FIG. The take-out part 10 is an integrated part including the cyclone separating part 4 and the filter part 6. An inflow port 17 is visible on the front side of the take-out part 10. As shown in FIG. 3, a lid 9 that closes the opening is provided at the lower end of the take-out portion 10. The lid portion 9 is normally kept closed by the locking portion 52 being in the locked state. When the user wants to discharge the dust accumulated in the cyclone separation unit 4, the locking state of the locking portion 52 is released by the user operating the opening operation portion 53, and the lid portion 9 uses the hinge 54 as a rotation axis by its own weight. Rotate and open as shown in FIG. FIG. 4 shows the take-out portion 10 with the lid portion 9 open as viewed obliquely from below.

  As shown in FIG. 5, the vacuum cleaner 1 includes a blower 7 for generating suction air inside the cleaner body 2. The suction air generated by the blower 7 enters the cyclone separator 4 from the inlet 17 in a state containing dust. In the cyclone separating unit 4, the suction air becomes a rotating flow, dust is separated by the centrifugal force of the rotating flow, and collected in a dust collecting case 5 below the cyclone separating unit 4. The air flow after separating the dust exits the cyclone separation unit 4 and passes through the filter 15 of the filter unit 6.

  The filter 15 is for collecting dust contained in the suction air coming out of the cyclone separation unit 4. The filter 15 has a pleated shape in which a plurality of mountain shapes are arranged in parallel when viewed from at least the downstream side. The place where the filter 15 is taken out alone is shown in FIG. FIG. 7 shows a cross-sectional view taken along the line VII-VII in FIG. In FIGS. 5 and 6, the outer peripheral shape of the filter 15 is shown as a rectangle for convenience of explanation. However, the outer peripheral shape of the filter 15 is actually determined in accordance with the shape of the frame to be stored. In the vacuum cleaner 1 according to the present embodiment, the filter 15 is housed in the filter frame 16 and disposed in the filter unit 6 as shown in FIG.

  As shown in FIG. 5, the filter unit 6 includes a filter dust removal mechanism 61 on the downstream side of the filter 15. The filter dust removing mechanism 61 is for removing dust adhering to the surface on the upstream side of the suction air of the filter 15 by applying vibration to the filter 15, which will be described in detail later.

  FIG. 9 shows the filter unit 6 as viewed from the downstream side, that is, the blower 7 side. The filter unit 6 includes a filter dust removal mechanism 61. The filter dust removing mechanism 61 includes a rotating body case 67 and a rotating body 68 housed in the rotating body case 67. The rotating body case 67 has several leg-shaped support portions projecting radially outward. 64 is fixed to the filter frame 16. The rotating body 68 is disposed in the vicinity of the filter 15 on the downstream side of the filter 15 in a state of being rotatable about a central axis 69 serving as a rotation axis parallel to the traveling direction of the suction air. The outer edge of the rotating body 68 is partially covered by the rotating body case 67, but the central portion is exposed and attached so as to be rotatable around the central axis 69. The center axis 69 is a virtual center line for the rotating body 68. Therefore, the central shaft 69 does not necessarily have a core member. The rotating body 68 includes a knob 68 a at a position not covered by the rotating body case 67. The knob 68a protrudes forward, and the user can rotate the rotating body 68 by pinching the knob 68a and turning it around the central axis 69. The place which took out the rotary body 68 independently and turned it over is shown in FIG. In FIG. 10, the upper side is the side facing the filter 15. A vibration generating projection 68 b that projects toward the filter 15 is provided on the back side of the rotating body 68, that is, the surface 68 c facing the filter 15. The vibration generating protrusion 68b is for scratching the apexes of a plurality of pleat-shaped ridges of the filter 15 by the rotation of the rotating body 68. The vibration generating protrusion 68b protrudes at a height that contacts the filter 15.

(Action / Effect)
As the rotating body 68 rotates around the central axis 69, the vibration generating projections 68b repeatedly collide with a plurality of mountain-shaped top portions of the filter 15. In other words, the vibration generating projection 68b scratches the surface of the filter 15 so as to draw an arc. Due to this arc-shaped scratching operation, vibration is generated in the filter 15. Most of the dust adhering to the filter 15 is adhering to the upstream side, that is, the back side in FIG. Therefore, in order to clean the filter 15, the user may hold the filter unit 6, pinch the knob 68 a and rotate the rotating body 68. By doing so, the dust adhering to the filter 15 is detached from the filter 15 due to vibration generated in the filter 15 and falls. Here, if each of the plurality of mountain shapes constituting the pleat shape of the filter 15 has a shape extending in the vertical direction as shown in FIG. 9, the dust dropped from the filter 15 has another mountain shape. It is particularly preferable because it can drop smoothly without being blocked.

  When the filter 15 is vibrated and the dust is dropped, if the space on the back side of the filter 15 of the filter unit 6 is sealed, the dust that has fallen in the lower part of the interior of the space is collected. What is necessary is just to discharge the collected dust together. This is the case when the filter unit 6 is combined with the cyclone separating unit 4 and integrated as the extraction unit 10 as shown in FIG. In that case, the user may hold the take-out unit 10 and rotate the rotating body 68.

  When the space on the back side of the filter 15 of the filter unit 6 is not sealed, for example, when the filter unit 6 is separated from the cyclone separating unit 4 and taken out alone, the user can view the image on a trash can, a trash bag, or the like. What is necessary is just to rotate the rotary body 68, holding the filter part 6 so that the surface of the filter 15 which can be seen in FIG. By doing so, the dust dropped from the filter 15 falls into a trash can, a trash bag or the like.

  If the vacuum cleaner includes such a filter dust removing mechanism in the filter unit, the user can quickly clean the filter with a simple operation without getting his hands dirty. In particular, in the present embodiment, the vibration generating projection does not simply reciprocate on a fixed line segment in the area where the filter is stretched, but is drawn so as to draw an arc in the area where the filter is stretched. Therefore, large vibrations can be generated uniformly throughout the entire region where the filter is stretched. Therefore, it is possible to make it difficult to cause a situation in which dust is not sufficiently removed and continues to accumulate in a partial area of the filter. The vacuum cleaner in the present embodiment can be a vacuum cleaner capable of generating sufficient vibration for dust removal over the entire area of the filter.

(Preferred matters regarding rotating bodies)
The rotating body 68 does not have to be a perfect circle, but preferably has a circular outer periphery with a central axis 69 as a rotation axis as shown in FIG. This is because a circular outer periphery can be used stably without worrying about the rotational orientation in the rotating body case 67. The "circular outer periphery" here includes not only a circular outer periphery in a strict sense but also a configuration in which teeth are provided along the circular outer periphery.

  The rotating body 68 has a wheel shape including a central portion 682, an annular portion 681 disposed on the outer periphery, and an intermediate portion 683 connecting the central portion 682 and the annular portion 681, and the vibration generating protrusion 68b. Is disposed in the annular portion 681. Such a configuration is preferable. This is because if the center part and the annular part are connected at the intermediate part, the amount of material required to form the rotating body can be saved, and a stable strength can be maintained with a small amount of material. Because. Further, if the vibration generating protrusion is arranged in the annular portion, the vibration generating protrusion can draw an arc with a large radius, and as a result, vibration can be generated over a long distance.

  A plurality of vibration generating protrusions 68b are arranged in the annular portion 681 so as to be arranged at equal intervals in the circumferential direction. Such a configuration is preferable. This is because with such a configuration, vibrations can be evenly generated at each location through the rotation of the rotating body.

  The vibration generating protrusion 68b is arranged such that a rod-like body having a rounded tip extends in a direction parallel to the rotation axis. Such a configuration is preferable because vibrations can be generated by scratching the vertices of a plurality of pleat-shaped ridges without damaging the filter as much as possible.

  The rotating body 68 is made of resin, and the vibration generating projection 68b is formed together with the rotating body 68 by integral molding. By using resin as described above, the rotating body can be reduced in weight and the filter can be prevented from being damaged as much as possible. Furthermore, the number of parts can be reduced by integral molding.

(Tooth group)
Since the vacuum cleaner 1 in this Embodiment is equipped with the preferable form besides the above-mentioned, this is demonstrated in detail below. As shown in FIG. 2, the electric vacuum cleaner 1 includes a main body 2r that houses the blower 7, and a dust container for storing dust inside. The “main body” here is not the vacuum cleaner main body 2 but the remaining portion where the take-out portion 10 is removed from the vacuum cleaner main body 2. That is, the main body 2r is a part of the cleaner body 2. On the other hand, the cyclone separator 4 corresponds to a dust container. This dust container is detachable from the main body 2r. Since the filter 15 is included in the filter unit 6 as shown in FIG. 9, the filter 15 is integrated with the dust storage unit, that is, the cyclone separation unit 4 when the dust storage unit is extracted from the main body 2 r. As shown in FIG. The main body 2r after the dust container is taken out is shown in FIG. The main body 2r is provided with a lattice 71 so as to cover an opening through which the blower 7 (not visible in FIG. 11) sucks wind. A net (not shown) is stretched between the lattices 71. A blower 7 is installed behind the lattice 71. A resin member 70 is installed on one side of the lattice 71. In the present embodiment, the member 70 is a part of the filter dust removal mechanism 61.

  As shown in FIGS. 9 and 10, the rotary body 68 included in the filter dust removing mechanism 61 has a first tooth group 68d on the outermost periphery. As shown in FIG. 11, the filter dust removing mechanism 61 includes a second tooth group 70d disposed on the main body 2r so as to mesh with the first tooth group 68d. That is, the second tooth group 70d is provided on one side of the member 70 included in the main body 2r.

  FIG. 12 shows a schematic perspective view of the cleaner body 2 showing the positional relationship between the first tooth group 68d and the second tooth group 70d in a state where the take-out part 10 is attached to the main body part 2r. FIG. 12 shows the grid 71 as viewed from the take-out portion 10 side. In FIG. 12, only the rotating body case 67 and the rotating body 68 are displayed in the extraction unit 10. In the rotating body 68 shown in FIG. 12, the vibration generating projection 68b protrudes toward the front of the page, and the knob 68a protrudes toward the back of the page. As shown in FIG. 12, the left end of the first tooth group 68d in FIG. 12 and the lower part of the second tooth group 70d are engaged with each other. During the operation of attaching / detaching the cyclone separating unit 4 as the dust container to / from the main body 2r, the rotating body case 67 moves linearly in the vertical direction, so that the rotating body 68 that is housed inside the rotating body case 67. Also move linearly up and down. The second tooth group 70d is linearly arranged in the vertical direction corresponding to the rotary body 68 moving linearly in the vertical direction. That is, the first and second tooth groups 68d and 70d have the first tooth group 68d and the second tooth group 68d and the second tooth group during at least one of the operation of attaching the dust container to the main body 2r and the operation of removing from the main body 2r. It arrange | positions so that the rotary body 68 can be rotated by meshing | engaging with the tooth group 70d.

  With this configuration, the rotating body case 67 moves up and down each time an operation for attaching or removing the take-out portion 10 including the dust container to the main body 2r is performed, so that the first case is performed. Further, the rotating body 68 is somewhat rotated by the meshing of the second tooth groups 68d and 70d. Referring to FIG. 12, the rotating body 68 rotates counterclockwise in the rotating body case 67 during the removing operation, and the rotating body 68 rotates clockwise in the rotating body case 67 during the attaching operation. . In the rotation of the rotating body 68 generated in this manner, a larger rotation angle is preferable because a scratching operation is performed over a longer distance, but a certain effect can be obtained even when the rotation angle is small. In any case, since this rotation occurs, the vibration generating projections 68b regularly arranged over the entire circumference of the rotating body 68 scratch the surface of the filter 15 (see FIG. 9), so that the filter 15 is evenly vibrated and adhered. It is possible to drop off dust. In particular, since the attaching / detaching operation of the dust container causes the rotation of the rotating body 68 in this way, the user bothers to pay attention to the dirt on the filter unit 6 and rotate the knob 68a. Since it does not have to be performed periodically, there is no problem that the user forgets to remove the filter dust, which is preferable. This is because, in this embodiment, even if the user is completely unaware of the filter dust removal, the filter dust removal is naturally performed when the dust container is attached or detached.

(Embodiment 2)
(Filter dust removal mechanism)
With reference to FIGS. 9 and 10 again, the filter dust removing mechanism according to the second embodiment of the present invention will be described. The filter dust removal mechanism in the present embodiment is, for example, the filter dust removal mechanism 61 described in the first embodiment. That is, this filter dust removing mechanism 61 is used by being installed in the cleaner body 2 as shown in FIG. 5, for example, if it is a cleaner, and collects dust by allowing gas to pass in a certain direction. It is a filter dust removal mechanism for installing in the downstream of the filter 15 of this. As shown in FIG. 9, the filter dust removing mechanism 61 includes a rotating body 68 having a surface for facing the filter 15 and a support portion 64. The support portion 64 supports the rotating body 68 so as to be close to the filter 15 on the downstream side of the filter 15 in a state of being rotatable about a central axis 69 as a rotation axis parallel to the passing direction of the filter 15. It is a support member. As shown in FIG. 10, the surface 68 c of the rotating body 68 that faces the filter 15 is provided with a vibration generating protrusion 68 b that scratches the surface of the filter 15 by the rotating operation of the rotating body 68.

(Action / Effect)

The rotating operation of the rotating body may be performed manually by the user or may be interlocked with the movement of other moving parts. Alternatively, the rotating operation of the rotating body may be performed by obtaining power from some driving source such as a motor. In the filter dust removal mechanism in the present embodiment, dust removal over almost the entire area of the filter can be realized by a simple mechanism.

  In addition, although the example which applies a dust removal mechanism to a vacuum cleaner has been shown so far, in air purifiers, heating appliances, air conditioners, blowers, etc., dust collection is performed by allowing gas to pass through. As long as the filter is present, the filter dust removing mechanism according to the present invention can be applied.

  In addition, a combination of a filter and a filter dust removal mechanism such as the filter unit 6 shown in FIG. 9, that is, a filter with a dust removal mechanism is also an object of the present invention. That is, this filter with a dust removal mechanism includes a filter for collecting dust by allowing gas to pass in a fixed direction, a rotating body having a surface facing the filter, and the rotating body in parallel to the passing direction of the filter. And a support member for supporting the filter so as to be close to the filter on the downstream side of the filter in a state of being rotatable around a rotating shaft. Furthermore, a vibration generating projection for scratching the surface of the filter by a rotating operation of the rotating body is provided on a surface of the rotating body facing the filter. In such a filter with a dust removal mechanism, dust removal of the filter can be easily and uniformly performed, so that it can play a role of collecting dust over a long period of time while maintaining high performance as a filter.

  In addition, the said embodiment disclosed this time is an illustration in all the points, Comprising: It is not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and includes all modifications within the scope and meaning equivalent to the terms of the claims.
