[0020]

BEST MODE FOR CARRYING OUT THE INVENTION A dust collector according to an embodiment will be described below with reference to the accompanying drawings. Moreover, in the following description, dust such as cotton dust, dust, and waste paper is simply referred to as dust.

FIG. 1 shows a cleaning device 1 according to the embodiment. The cleaning device 1 includes a dust mop 100 and a fixed dust collector 400.

The dust mop 100 is a dust control method proposed by the Bell Telephone Company of the United States in 1955 (for example, "Building Management Handbook", edited by the Building Management Handbook, edited by the Editorial Committee, Takeo Morimura, Showa 57).
It is a type of chemical cloth manufactured according to the first edition issued on September 20, 2014, see page 252), handle 101
And the mop body 102. Mop body 102
Is a product obtained by coating or impregnating a spinning yarn with an adsorbent. In addition to the dust mop 100, a cross-type chemical cloth, a roll paper type chemical cloth, or the like may be used.

As the adsorbent applied to or impregnated in the dust mop 100, (i) water is not used, and dust is removed, (ii)
It is preferable to satisfy the conditions such as collecting dust without scattering it, and (iii) not easily releasing the dust once taken in.

Generally, an adsorbent used is an oil agent which has a low viscosity and does not dry at room temperature. As the oil agent, mineral oil is generally used. Mineral oils such as minerals (for example, spindle oil), paraffins (for example, liquid paraffin), silicones (for example, silicon oil), water-based (for example, water-based oil agents), and Tefnan-based mineral oils are used as adsorbents. To be done. In some cases, the mop body 102 may be coated or impregnated with an adhesive such as an acrylic adhesive or a urethane adhesive.

Further, instead of the dust mop 100, it is a mop made of a material that is easily charged, for example, a chemical fiber such as a filament yarn of olefinic hydrocarbon, and a voltage of about 10 KV is applied by a corona discharge device to perform electret processing. The mop 300 described above may be used. The mop 300 having the above configuration captures dust by utilizing the dust absorbing action of static electricity. The appearance of the mop 300 is substantially the same as that of the mop 100, and thus is not particularly shown.

The dust collector 400 is a device for sucking relatively large dust such as paper scraps collected by the dust mop 100 in the vicinity of the suction port provided on the side of the device into a built-in dust collecting container. 2A is a perspective view of the dust collector 400, FIG. 2B is a sectional view taken along line bb ′ of the internal structure of the dust collector 400 as viewed in the direction B, and FIG. FIG. 7 is a sectional view taken along the line cc ′ of the internal structure of the dust collector 400 as viewed from the direction C.

As shown in FIG. 2A, the dust collector 40
Reference numeral 0 denotes a front surface, that is, a dust suction port 401 provided in a lateral direction (hereinafter, simply referred to as side) of the apparatus, two exhaust ports 404 and 405 on both sides, and an opening for accommodating the dust mop 100 at the top. The unit 406 is provided. The suction port 401 is equipped with a hood 402 as a guiding unit that guides dust rising near the suction port 401 to the suction port.

In addition, the suction port 401 has a partition plate 40 as a partitioning means which narrows the opening area of the suction port 401 to increase the suction speed and opens according to the size of dust to be sucked.
3 is fixed to the upper part. The partition plate 403 has a suction port 4
It is preferable to provide it over the entire width of 01. Partition plate 403
Is made of a flexible material such as a plate-shaped rubber that is formed so as to incline or be rolled up in the intake direction, and opens the passage according to the size of the sucked dust. By providing the partition plate 403, the intake speed can be increased without reducing the size of dust that can be sucked. In addition, the flexibility and the vertical size of the partition plate 403 depend on the dust collector 400.
In consideration of the suction force of the above, it is possible to adopt the one having the value that maximizes the dust suction efficiency.

Instead of the partition plate 403, a partition plate 403 'made of a hard material that is formed so as to be inclined or wound in the intake direction is hung swingably from above the suction port 401. Is also good. In this case, the weight and the vertical dimension of the partition plate 403 'may be set to a value that maximizes the dust suction efficiency in consideration of the suction force of the dust collector 400. Further, when adopting the configuration, a spring that biases the partition plate 403 ′ in a direction opposite to the intake direction may be attached.

Further, as shown in a partially enlarged view in FIG. 3, instead of providing the partition plate 403, a semi-cylindrical member 403 ″ is provided in the passage 412 as a rectifying means for intake air.
For example, it may be provided on the upper side near the suction port 401. As a result, the flow of intake air can be made smooth and large dust can be smoothly sucked. Note that the shape of the member 403 ″, and the arrangement position and the arrangement method in the passage 412 are not limited as long as the rectifying effect is recognized.

Referring again to FIG. Exhaust ports 404, 40
5 is directed upward, for example, to a position higher than the suction port 401 so that the exhaust gas does not scatter not only dust collected near the suction port 401 by the dust mop 100 but also small dust around the dust collector 400. Open not only directly upward, but also diagonally upward).

The inside of the dust collector 400 has two chambers 41.
0 and room 420. As shown in FIG. 2B, the room 410 has an opening 411 on the bottom surface that communicates with the room 420. Further, the chamber 410 is provided with an opening 413 of a passage 412 leading to the suction port 401 at a position higher than the bottom surface of the dust collecting container 415 built therein. The structure serves as a means for preventing dust once stored in the dust container 415 from flowing back to the suction port 401. In addition, or instead of the structure, a check valve may be used as the check valve.

The shape of the passage 412 viewed from the direction C in FIG. 2 (a) has a constricted shape similar to the cross section of a jug with a long neck or a flask. It is preferable that the degree of constriction from the width of the corresponding suction port 401 to the width of the upper portion of the passage 412 corresponding to the constriction is gentle rather than steep because the passage loss amount of the intake air volume is smaller.

A net 417 and a lid 418 are provided on the dust collecting container 415. The net 417 is attached so as to be openable and closable within a range from 9 o'clock to 12 o'clock if it is represented by a short hand of a clock around the shaft 417a. Similarly, the lid 418 has a shaft 418a.
It is attached so as to be openable and closable around 9 o'clock to 12 o'clock, and the opening 406 can be sealed. Axis 4
18a is a shaft 417a for facilitating opening and closing of the net 417.
Install it closer to the wall than.

When the motor 422 is rotated with the net 417 and the lid 418 closed, air is sucked from the suction port 401 along the arrow shown in the figure. As a result, relatively large dust such as waste paper collected by the dust mop 100 near the suction port 401 is sucked into the dust collecting container 415.

Further, the suction port 40 equipped with the hood 402
By vibrating the dust mop 100 near 1, the dust collected by the dust mop 100 can be effectively collected in the dust container 415. This makes the dust mop 100
The dust collecting power of the can be regenerated, and the usable period of the light mop can be extended.

The dust collecting container 415 is provided with a dust collecting filter 416 having excellent ventilation in an opening provided at the bottom. Suction port 4
The air containing dust sucked from 01 is filtered when passing through the dust collecting filter 416. Also, the dust container 4
15 is by opening both the net 417 and the lid 418,
It can be taken out through the opening 406.

When the motor 422 is rotated with the net 417 and the lid 418 closed, as shown in FIG. 2B, since the lid 418 and the net 417 are separated from each other, suction is performed from the suction port 401. Entrapped dust may be caught on the net 417. In order to improve this, as shown in FIG. 4A, a lid 41 provided so as to be in close contact with each other in a closed state.
8'and the net 417 'may be adopted. If the lid 418 'is represented by the hour hand of the clock centering on the shaft 418'a, it starts from 9 o'clock.
Install so that it can be opened and closed within the 2 o'clock range. The shaft 418'a
Is provided at a position where the passage 412 extends upward when the lid 418 ′ is opened, as shown in FIG. 4 (b). Net 41
7'is mounted so as to be openable and closable in the range from 12:00 to 3:00 if it is represented by a short hand of the clock centering on the shaft 417'a. As shown in FIG. 4C, the shaft 417'a has a lid 418 '.
It is provided at the opposite end. By adopting the lid 418 ′ and the net 417 ′ having the configuration, it is possible to prevent the dust sucked from the suction port 401 from being caught on the net 417 ′ in the middle.

On the other hand, with the lid 418 open, the motor 42
When 2 is rotated, not only the suction port 401 but also the net 41
Intake is also performed from 7. As shown in FIG. 5, in this state, the dust mop 100 is inserted from the opening 406 and moved up and down, or by directly sliding it on the net 417, the dust collected by the dust mop 100 is wiped off to regenerate the dust suction force. You can This makes the dust mop 100
Can extend the available time. In addition, it is better to suck the dust collected by the dust mop 100 by the method.
It is more effective than shaking the dust mop 100 in front of the suction port 401 because dust does not fly up.

As shown in FIG. 4B, the lid 41
In the case of using 8 ′ and the net 417 ′, when the lid 418 ′ is opened, air is sucked only by the net 417 ′ in place of the suction port 401, so that the dust collected by the dust mop 100 is stronger from the opening 406. Can be sucked up.

Referring again to FIG. As shown in FIG. 2C, the chamber 420 accommodates a motor 422 having an intake fan 421, and has openings 425, 426 of passages 423, 424 communicating with exhaust ports 404, 405 at the bottom.

In order to prevent dust around the dust collector 400 from scattering, a speed reducing means (mechanism) for reducing the velocity of the air discharged from the exhaust port to a velocity at which dust around the exhaust port is not scattered. As a result, the cross-sectional area of each of the passages located downstream of the suction port 401 is made larger than the opening area of the suction port 401. Specifically, rather than the opening area of the suction port 401, the cross-sectional area of the passage 412, the opening 425,
The total cross-sectional area of 426, the total cross-sectional area of the passages 423 and 424, and the total opening area of the exhaust ports 404 and 405 are set to be large. By adopting this configuration, it is possible to gently exhaust air and prevent dust around the dust collector 400 from scattering. Moreover, exhaust noise can be reduced by adopting the configuration. Also, the passages 423, 4
By making 24 as long as possible, the noise leaked to the outside can be further reduced.

In order to further enhance the sound deadening effect, the passage 4
Although a sound deadening means such as a sound deadening wall, which functions effectively, may be provided in 23, 424, as a result, it is necessary to take care not to scatter the dust around the dust collector 400 due to the high exhaust speed. However, as described above, the exhaust ports 404,
Since the 405 is turned upward, the dust collecting device 400 can be exhausted.
This does not apply if it is possible to prevent dust around it from scattering sufficiently.

It should be noted that two moving wheels may be provided at the rear side of the dust collector 400, that is, at both ends of the bottom surface on the side opposite to the side where the suction port 401 is provided, so that it can be moved easily. When the structure is adopted, the dust collector 400 is normally fixed with the front side of the bottom surface (the suction port 401 side) attached to the floor. At the time of movement, the dust collector 400 is tilted rearward and pulled around using the wheels.

By providing such wheels, the dust collector 4 is provided near the doorway of each room to be cleaned with the dust mop 100.
It becomes easy to move 00 and fix it in place. This makes it possible to shorten the distance for moving the dust collected by the dust mop 100 to the dust collecting device 400, and prevent the collected dust from scattering during the movement.
