Then, the pile group of the mop is pressed against the comb-like member to remove the dust attached to the mop, and the dust is collected by the dust collection pack through the suction opening.

JP 2012-245318 A

  However, the vacuum cleaner described in Patent Document 1 is configured such that the suction path from the suction opening to the dust collection pack is short and rapidly rises in the vertical direction. Therefore, it is difficult to collect heavy dust such as pebbles. In particular, when the dust collection pack is clogged, there is a problem that the dust collection performance is extremely reduced. In addition, since the area of the suction opening is small, the suction wind may be swirled in front of the dust collection pack, which may cause noise.

  An object of the present invention is to provide a dust collection apparatus that easily removes dust attached to a mop or the like and suppresses noise when removing the dust.

In order to solve the above-mentioned conventional problems, the dust collection device of the present invention comprises a main body having a suction port for sucking dust, an electric blower for generating suction wind, and dust collection for storing dust sucked from the suction port. A chamber, and an internal flow path comprising a duct and a passage extending inward from the suction port, the electric blower and the dust collection chamber being disposed above the duct, the duct being The duct extends from the suction port to the rear of the dust collecting device, and the cross-sectional area gradually decreases from the suction port toward the passage in the main body, and the duct and the passage are The back side of the dust collector communicates, and the passage extends upward from the back of the duct.

While being able to efficiently carry dust to the dust collection chamber, it is possible to realize a dust collector that suppresses noise when dust is removed.

Embodiment
Hereinafter, the dust collecting apparatus according to the embodiment of the present invention will be described with reference to FIGS. 1 to 3.

  FIG. 1 is a perspective view of a dust collecting apparatus according to an embodiment of the present invention. FIG. 2 is a side view of the dust collector in the same embodiment. FIG. 3 is a rear view of the dust collector in the same embodiment.

  As shown in FIGS. 1 to 3, the dust collecting apparatus according to the present embodiment includes a main body 1, a dust collection chamber 3 housed in the main body 1, and a hose 4 etc. detachably connected to the main body 1. It is done.

  The main body 1 is provided with a suction port 2 that opens forward on the lower side of the front surface, and absorbs dust. The dust collection chamber 3 is provided above the suction port 2 so as to be extractable from the front side of the main body 1. Then, when the user pulls out the dust collection chamber 3, the dust collected inside the main body 1 can be taken out and discarded. In the dust collection chamber 3, for example, a dust collection bag 12 (see FIG. 4) is set, and dust is collected in the dust collection bag.

  The hose 4 is rotatably mounted on the upper surface substantially central portion (including the central portion) of the main body 1 above the dust collection chamber 3. The hose 4 is made of, for example, a soft material such as elastomer, rubber, polyvinyl chloride (PVC), etc., and is configured to be stretchable and bendable.

  The power button 5 shown in FIG. 1 is disposed on the upper surface of the main body 1. When the user presses the power button 5, the dust collection apparatus starts and stops the operation of suction of dust.

  Further, as shown in FIG. 2, at the tip of the hose 4, a handle 8 is integrally provided. The user can easily detach the hose 4 from the main body 1 by holding the handle 8 of the hose 4.

  For example, a curved slope 7 is formed on the upper back side of the main body 1 (upper surface of the main body 1) so as to descend toward the rear of the main body 1.

The handle 6 has one end side on the upper surface of the main body 1 (specifically, the connection portion between the top portion and the upper surface of the slope 7 and the rear portion on the upper surface) and the other end side with the slope 7 (specifically, the slope 7 It is connected to the lower part). The outer periphery of the handle 6 is formed, for example, in a reverse U-shaped curved surface shape from one end side to the other end side. As a result, the hose 4 follows the curved surface shape of the handle 6 so that the main body 1 has a substantially inverted U shape (including an inverted U shape) when viewed from the side (see FIG. 2). Will be placed.

  In addition, a space of substantially inverted triangle (including inverted triangle) is formed between the handle 6 and the slope 7. Thus, the user holds the handle 6 to easily move the dust collection apparatus.

  Further, as shown in FIG. 3, for example, exhaust ports 9 are formed on the left and right side surfaces of the main body 1. The exhaust port 9 disperses and exhausts the exhaust discharged from the main body 1 toward the left and right of the main body 1. Further, for example, a power plug 10 is provided on the lower side of the back side of the main body 1. Then, the user can pull out the power plug 10 and connect it to a commercial power source.

  The dust collector of the present embodiment is configured as described above.

  Below, the internal structure and operation | movement of the dust collector in this Embodiment are demonstrated using FIG. FIG. 4 is a schematic view showing a state in which the dust collecting apparatus in the same embodiment is cut at the center.

  As shown in FIG. 4, the electric blower 11 is disposed substantially at the center (including the center) of the inside of the main body 1. Above the electric blower 11, for example, a dust collection chamber 3 including a dust collection bag 12 is disposed. An opening 13 is formed above the dust collection chamber 3 to be connected to and communicated with one end of the hose 4. Below the slope 7, a slope opening 17 connected to and communicated with the other end of the hose 4 is provided.

  Further, an internal flow passage 16 constituted by a duct 14 and a passage 15 is provided between the suction port 2 of the main body 1 and the slope opening 17. The duct 14 is provided from the suction port 2 below the front surface of the main body 1 to the rear of the dust collector. The passage 15 is provided in communication with the duct 14 upward from the duct 14 at the rear of the dust collecting apparatus. The dust drawn from the suction port 2 is configured to pass through the inside of the internal flow path 16 by the suction air generated by the electric blower 11.

  Further, as described above, the tip 4 a of the other end of the hose 4 is at the opening on the opposite side to the suction port 2 side of the internal flow passage 16, that is, the slope opening 17 provided on the lower side of the slope 7. Connected

  Thus, in a state where the hose 4 shown in FIG. 4 is stored in the main body 1, dust sucked from the suction port 2 is collected through the internal flow path 16, the slope opening 17, the hose 4 and the opening 13. Dust is collected at 12.

  On the other hand, the user can also remove dust from the tip 4 a of the hose 4 by removing the tip 4 a on the other end side of the hose 4 from the slope opening 17. In this case, the dust to be collected is collected in the dust collection bag 12 through the hose 4 and the opening 13. This corresponds to, for example, the case where the user sucks in the dust attached to the upper surface of the mop at the tip of the hose 4 and collects the dust on the dust collecting bag 12 through the above path.

  As described above, the operation of the dust collection apparatus of the present embodiment is performed.

Hereinafter, a structure for soundproofing the sound generated in the internal flow passage in the dust collection apparatus of the present embodiment will be described using FIG. 5 with reference to FIG.

  FIG. 5: is a disassembled perspective view which shows the duct and channel which comprise the internal flow path of the dust collector in the embodiment.

  As shown in FIG. 4 and FIG. 5, the suction port 2 is provided in the lower part of the main body 1 in proximity to the floor surface. The width of the suction port 2 is substantially equal to (including the same as) or slightly smaller than the width of the front surface of the main body 1.

  Further, the duct 14 described above is provided inward of the main body 1 from the suction port 2. As shown in FIG. 4, the duct 14 is configured to be lifted, for example, gently upward from the inside of the main body 1, that is, from the front to the rear of the main body 1. At this time, the duct 14 is provided in a shape in which the cross-sectional area gradually decreases from the suction port 2 side toward the passage 15 connected to the duct 14. Thereby, the duct 14 and the passage 15 are connected with securing air tightness. Here, the reduction in the cross-sectional area specifically corresponds to the case where the width of the duct 14 becomes narrow.

  In addition, the above-mentioned "toward the main body 1" is not limited to the meaning of going from the suction port 2 to the rear of the main body 1 as shown in FIG. For example, when the duct 14 is formed from the suction port 2 into the main body 1, it is not limited how far the duct 14 continues and how long the duct 14 is.

  That is, although the duct 14 is not shown exactly in FIG. 5, the duct 14 is formed, for example, in a substantially trumpet shape (including a trumpet shape) when viewed from above. Thereby, the cross-sectional area is gradually narrowed from the inlet (at the suction port 2 side) of the duct 14 toward the outlet (for example, the connection side with the passage 15). In the above, the substantially trumpet shape is described as an example, but the substantially trumpet shape is an example, and the present invention is not particularly limited to this shape. For example, the side surface 14b of the duct 14 shown in FIG. 5 may have a curved shape, and the cross-sectional area may be gradually narrowed.

  Due to the configuration of the duct 14, the vacuum pressure (suction force) gradually rises as going from the inlet of the suction port 2 to the back of the duct 14 (for example, the connection side with the passage 15). As a result, for example, large dust such as a large mass of pebbles can be sucked and collected smoothly.

  Further, a plurality of holes 18 are formed in the upper wall 14 a of the internal space of the duct 14 shown in FIG. 4. Then, a wall surface is formed upward from the upper wall 14a of the duct 14 so as to surround the hole 18, and a recess 21 having a substantially trapezoidal (including trapezoidal) shape shown in FIG. 5 is formed. A filter 19 having a substantially trapezoidal (including trapezoidal) shape is fitted in the recess 21. Furthermore, a cover 20 is provided to cover the recess 21 and to store the filter 19.

  The filter 19 is mainly made of a material having a low density, such as non-woven fabric and urethane foam. In this case, a coarse density material is preferable, but a coarse density material and a relatively high density material may be combined to constitute a filter. At this time, it is preferable to provide a material having a low density at a position facing the hole 18. Thereby, the muffling effect by the filter 19 can be enhanced.

  The muffling effect by the above configuration will be specifically described below.

That is, when the air is drawn, the air slides on the end face of the suction port 2 or a rib provided on the end face, thereby generating noise in a high frequency region. The generated noise is absorbed into the filter 19 from the holes 18 provided in the upper wall 14 a of the duct 14. Noise absorbed from the holes 18 diffuses as it passes through the filter 19. This reduces the energy of the sound. As a result, the offensive noise is reduced by the filter 19.

  The muffling effect of the above-described configuration is increased in proportion to the size of the opening area of the hole 18. That is, the larger the opening area of the hole 18, the greater the effect. Furthermore, the larger the volume of the filter 19, the larger the muffling effect. Therefore, a large muffling effect can be obtained by increasing the opening area of the hole 18 and the volume of the recess 21.

  In the following, regarding the specific configuration for reducing noise in the dust collection apparatus of the present embodiment, three examples will be described using FIGS. 6 to 8.

  FIG. 6 is a partial plan view showing the shape and arrangement of the holes of the dust collection device in the same embodiment. FIG. 7 is a partial plan view showing the shape and arrangement of the holes of the dust collection device in the same embodiment. FIG. 8 is a partial plan view showing the shape and arrangement of the holes of the dust collection device in the same embodiment.

  First, as shown in FIG. 6, the first example is a configuration in which the holes 18 having uniform sizes are aligned vertically and horizontally. At this time, the holes 18 preferably have a diameter of, for example, 0.5 mm to 10 mm. This is because when the diameter of the hole 18 is larger than φ10 mm, the sound passing through the hole 18 increases and the sound insulation effect at the non-open portion of the hole 18 decreases. However, it is preferable to provide a hole 18 as small as possible because a larger opening area can be secured. Thus, a larger opening area can be secured and the muffling effect can be enhanced, as compared to the case where the holes 18 are arranged irregularly.

  Next, as shown in FIG. 7, the second example is a configuration in which the plurality of holes 18 are arranged in a staggered manner while being mutually offset. Specifically, the plurality of holes 18 are composed of a plurality of rows and a plurality of columns, and the positions of the holes 18 in the odd rows and the even rows, or in the odd columns and the even columns are mutually offset. Thereby, the number of holes 18 can be increased even with the holes 18 of the same size as the first example. As a result, a larger opening area can be secured, and a higher silencing effect can be obtained.

  Furthermore, as shown in FIG. 8, the third example is a configuration in which the plurality of holes 18 are arranged by combining the holes 18 a and 18 b having different large and small opening areas. At this time, when the difference in the opening area of the large and small holes 18 is small, the hole 18 b having a small opening area is disposed beside the hole 18 a having a large opening area. Thereby, a large opening area can be obtained. In addition, when the difference in the opening area of the large and small holes 18 is large, for example, a plurality of small holes 18 b having a small opening area may be arranged beside the holes 18 a having a large opening area.

  Further, in the present embodiment, the holes 18 formed in the upper wall 14a of the duct 14 are provided so that the number of inlets on the suction port 2 side increases and the number decreases as going deeper. This is because, as described above, the duct 14 is provided in a substantially trumpet shape. As a result, after the noise in the high frequency region is absorbed at the inlet portion of the duct 14, an effect of gradually reducing the energy of the sound as it goes to the back of the duct 14 can be obtained.

  As described above, the dust collecting apparatus of the present invention comprises a main body having a suction port for sucking dust, an electric blower for generating suction air, a dust collection chamber for storing dust sucked from the suction port, and suction. And an internal flow passage consisting of a duct and a passage extending inward from the mouth. And a duct is comprised by the shape to which a cross-sectional area becomes small gradually toward the channel | path inside a main body from a suction opening. Thereby, dust can be efficiently carried to the dust collection chamber. Furthermore, it is possible to realize a dust collector that collects dust of large mass such as pebbles.

  Moreover, the dust collection apparatus of this invention may form several holes in the upper wall of a duct, and may arrange | position the filter for absorbing a sound above several holes. This allows the noise generated in the duct to be diffused through the holes and into the filter. As a result, noise in the high frequency region can be effectively reduced.

  Moreover, the dust collection apparatus of this invention may form the recessed part which arrange | positions a filter above several holes, and may further provide the cover body which covers a filter in a recessed part. As a result, the filter can be stably held, and noise in the high frequency region can be confined in the recess and further reduced.

  Further, in the dust collection apparatus of the present invention, the duct may be configured to be gradually inclined upward toward the passage in the main body. Thereby, the flow of suction air can be made smooth and dust can be efficiently carried to the dust collection chamber. As a result, even large dust such as pebbles can be easily collected.

  Further, in the dust collection device of the present invention, the filter may be configured in such a shape that the cross-sectional area gradually decreases toward the inner side of the main body. As a result, the suction force can be increased toward the inner side of the main body, and the dust can be transported to the dust collection chamber more efficiently.

  Further, in the dust collection apparatus of the present invention, the plurality of holes may be provided in the upper wall of the duct in vertical and horizontal alignment. Thereby, the area of the hole can be increased. As a result, noise can be effectively reduced.

  Further, in the dust collection apparatus of the present invention, the plurality of holes may be provided on the upper wall of the duct in a staggered manner. Thereby, a larger opening area can be secured. As a result, noise can be further reduced.

  Moreover, the dust collection apparatus of this invention may provide the some hole from which opening area differs in the upper wall of a duct. Thereby, a larger opening area can be secured. As a result, the noise reduction effect can be further improved.

  The present invention is widely applicable to dust collectors capable of removing dust from a suction port.
