[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0010] [First embodiment] Fig. 1 is a perspective view of a dust collector 1 according to a first embodiment. Fig. 2 is a top view of the dust collector 1. Fig. 3 is a cross-sectional view of the dust collector 1 taken along line III-III in Fig. 2. Fig. 4 is a cross-sectional view of the dust collector 1 taken along line IV-IV in Fig. 2. The configuration of the dust collector 1 will be described with reference to Figs. 1 to 4.

[0011] As shown in Fig. 1, the dust collector 1 has a three-dimensional rectangular parallelepiped shape. Here, in Fig. 1, the depth direction of the dust collector 1 is referred to as the X direction, the width direction is referred to as the Y direction, and the up-down direction is referred to as the Z direction. In the following description, particularly in Fig. 1, the depth side in the X direction is referred to as the X1 side, the front side is referred to as the X2 side, the left side in the Y direction is referred to as the Y1 side, the right side is referred to as the Y2 side, the upper side in the Z direction is referred to as the Z1 side, and the lower side is referred to as the Z2 side.

[0012] 3, the dust collector 1 includes an accommodation chamber 10 that accommodates the cleaning tool 4 and removes dust adhering to the cleaning tool 4, a dust collection unit 11 that collects the removed dust, and a negative pressure source 12 that serves as a power source for moving the dust from the accommodation chamber 10 to the dust collection unit 11. The accommodation chamber 10 is located on the X2 side of the dust collector 1. The dust collection unit 11 and the negative pressure source 12 are located on the X1 side of the dust collector 1. The dust collection unit 11 is located on the Z1 side of the negative pressure source 12.

[0013] The dust collector 1 further includes a negative pressure flow path 13 that connects the negative pressure source 12 and the storage chamber 10. The negative pressure flow path 13 has a first negative pressure flow path 130 and a second negative pressure flow path 131. The first negative pressure flow path 130 is a flow path that connects the storage chamber 10 and the dust collecting unit 11, and extends in the Z direction between the storage chamber 10 and the dust collecting unit 11. The second negative pressure flow path 131 is a flow path that connects the dust collecting unit 11 and the negative pressure source 12.

[0014] As shown in Fig. 2 and Fig. 3, the storage chamber 10 is a bottomed cylindrical space defined by a rectangular bottom wall 104, a first side wall 100 extending in the Z1 direction from the edge of the bottom wall 104 on the X1 side, a second side wall 101 extending in the Z1 direction from the edge of the bottom wall 104 on the X2 side, a third side wall 102 extending in the Z1 direction from the edge of the bottom wall 104 on the Y1 side, and a fourth side wall 103 extending in the Z1 direction from the edge of the bottom wall 104 on the Y2 side, and has an opening 105 that opens to the Z1 side at the Z1 side end. The first side wall 100 and the second side wall 101 face each other in the X direction. The third side wall 102 and the fourth side wall 103 face each other in the Y direction.

[0015] As shown in Fig. 3, the accommodation chamber 10 is provided with three suction ports 100a arranged side by side in the Z direction, penetrating the first side wall 100 in the X direction. The suction ports 100a connect the accommodation chamber 10 to the first negative pressure flow path 130. The suction ports 100a are rectangular (see Fig. 4) and are arranged approximately evenly in the Z direction. The suction ports 100a are provided only in the first side wall 100.

[0016] As shown in Fig. 3 and Fig. 4, the first side wall 100 of the storage chamber 10 has three first scraping portions 106 arranged side by side in the Z direction for scraping off dust adhering to a wiping body 41 (see Fig. 5) of the cleaning tool 4 described below. Each of the three first scraping portions 106 is provided on the Z1 side of each of the three suction ports 100a. The first scraping portions 106 are plate-shaped members extending in the Y direction. The first scraping portions 106 have a plurality of semicircular slits 106a on the edge on the X2 side that divide the first scraping portions 106 in the Y direction (see Fig. 2).

[0017] In the storage chamber 10, four second scraping portions 107 are provided in the X direction on each of the third and fourth side walls 102, 103. The second scraping portions 107 are plate-shaped members extending in the Z direction. The second scraping portions 107 have the same shape as the first scraping portion 106 and serve the same purpose. Since the second scraping portions 107 extend in the Z direction, the second scraping portions 107 can be in constant contact with the wiping body 41 while the wiping body 41 is moving in the Z direction in the storage chamber 10, and can efficiently scrape off dust.

[0018] As shown in FIG. 3, the second side wall 101 has an upper wall portion 101a located on the Z1 side and a lower wall portion 101c located on the Z2 side of the upper wall portion 101a. A distance L2 between the lower wall portion 101c and the first side wall 100 is shorter than a distance L1 between the upper wall portion 101a and the first side wall 100. In other words, the lower wall portion 101c is closer to the first side wall 100 than the upper wall portion 101a. The second side wall 101 further has a slope portion 101d that slopes from the lower end of the upper wall portion 101a toward the upper end of the lower wall portion 101c toward the first side wall 100 side (X1 side). The slope portion 101d connects the lower end of the upper wall portion 101a and the upper end of the lower wall portion 101c. The lower wall portion 101c and the slope portion 101d constitute a guide portion 101b that guides the wiping body 41 toward the first side wall 100.

[0019] The dust collection unit 11 has a filter 110 that collects dust, a dust collection unit inlet 111 connected to a first negative pressure flow path 130, and a dust collection unit outlet 112 connected to a second negative pressure flow path 131. The filter 110 is provided in the dust collection unit 11 so as to block the dust collection unit outlet 112. The dust collection unit inlet 111 is not blocked by the filter 110. The filter 110 has a fine mesh structure. Dust is captured by the filter 110 due to the mesh structure and accumulates in the dust collection unit 11.

[0020] The dust collector 1 further includes an exhaust port 14. The exhaust port 14 is an opening for discharging the air sucked by the negative pressure source 12 to the outside of the dust collector 1. The negative pressure source 12 in this embodiment is an electric blower. When power is supplied to the negative pressure source 12, the negative pressure source 12 is activated.

[0021] Next, an example of the cleaning tool 4 used in this embodiment will be described with reference to Fig. 5. Fig. 5 is a schematic diagram of the cleaning tool 4 showing a storage position (see Fig. 5(a)) in which the cleaning tool 4 is stored in the dust collector 1, and a position (cleaning position) when cleaning (see Fig. 5(b)). The cleaning tool 4 is a mop. The cleaning tool 4 has a long handle 40 and a long wiping body 41 attached to a tip 40a of the handle 40.

[0022] The wiping body 41 is the mop portion of the mop. The wiping body 41 is composed of a large number of fiber piles. By pressing the wiping body 41 against the floor surface to clean, dirt and other debris adheres to the wiping body 41. The wiping body 41 is rotatable around an axis extending in a second direction (for example, the direction of the paper in FIG. 5) perpendicular to the first direction in which the handle 40 extends. The cleaning tool is not limited to the mop of this embodiment, and may be a cleaning tool with a long pile length such as a resin pile or a brush, or may be a cleaning tool made of nonwoven fabric.

[0023] When the cleaning tool 4 is in the stored posture, the wiping body 41 extends along the first direction together with the handle 40. The wiping body 41 rotates around an axis extending in the second direction, thereby extending in a direction perpendicular to the first direction (for example, the left-right direction in FIG. 5), and the cleaning tool 4 takes the cleaning posture.

[0024] Next, the operation of the dust collector 1 of the present disclosure will be described with reference to FIG.

[0025] FIG. 6 is a cross-sectional view similar to FIG. 3 when the cleaning tool 4 is accommodated in the dust collector 1. The cleaning tool 4 is in an accommodation position with the first direction facing the Z direction, and is inserted into the accommodation chamber 10 from the Z1 side through the opening 105. When the cleaning tool 4 is inserted into the accommodation chamber 10, the wiping body 41 is guided toward the first side wall 100 by the guide portion 101b. As a result, the wiping body 41 is located on the X1 side in the accommodation chamber 10 and is in a state where it is easy to come into contact with the first side wall 100. When the cleaning tool 4 is moved in the Z direction in a state where the wiping body 41 is easy to come into contact with the first side wall 100, the wiping body 41 is scratched by the first scraping portion 106 and the second scraping portion 107. As a result, dust adhering to the wiping body 41 is scraped off.

[0026] The air in the dust collector 1 flows from the storage chamber 10 to the exhaust port 14 due to the pressure difference generated by the negative pressure source 12. When the negative pressure source 12 is activated, the space in the dust collection section 11 and the negative pressure flow path 13 becomes negative pressure. Here, negative pressure is a pressure lower than atmospheric pressure. Since the pressure in the storage chamber 10 is atmospheric pressure, the air in the storage chamber 10 is sucked into the negative pressure flow path 13 due to the pressure difference with the negative pressure in the negative pressure flow path 13.

[0027] 6 shows an air flow F1 containing dust (dashed line with a large gap) and an air flow F2 not containing dust (dashed line with a small gap). The scraped-off dust is sucked into the suction port 100a together with air by the operation of the negative pressure source 12. At this time, since the wiping body 41 is in a state where it is likely to come into close contact with the first side wall 100, at least a part of the suction port 100a is blocked by the numerous fiber piles of the wiping body 41. This strengthens the negative pressure in the negative pressure flow path 13, improving the suction force.

[0028] The air containing dust passes upward through the first negative pressure flow path 130 and enters the dust collector 11 from the dust collector inlet 111. The dust-containing air then travels toward the dust collector outlet 112. Because the dust collector outlet 112 is blocked by the filter 110, the dust that arrives at the dust collector outlet 112 is captured by the filter 110. As a result, the dust and the air are separated. The air that does not contain dust passes through the second negative pressure flow path 131 and enters the negative pressure source 12, and is discharged to the outside of the dust collector 1 through the exhaust port 14.

[0029] The dust collector 1 according to this embodiment has the following advantages.

[0030] (1) A cleaning tool 4 having a handle 40 extending in a first direction and a long wiping body 41 rotatably attached to a tip 40a of the handle 40 around an axis extending in a second direction perpendicular to the first direction, the wiping body 41 being inserted from the Z1 side while extending along the first direction and with the first direction facing the Z direction into an accommodation chamber 10 in which the wiping body 41 is accommodated; A negative pressure source 12; a negative pressure flow path 13 connected to a negative pressure source 12; a first side wall 100 which is one of the side walls defining the storage chamber 10 and through which a suction port 100a which connects the storage chamber 10 to the negative pressure flow path 13 penetrates; a guide portion 101b for guiding the wiping body 41 toward the first side wall 100; Equipped with.

[0031] As a result, the guide portion 101b makes it easier to bring the wiping body 41 into close contact with the first side wall 100, so that at least a portion of the suction port 100a is blocked by the wiping body 41. This strengthens the negative pressure in the first negative pressure flow path 130, increasing the pressure difference between the storage chamber 10 and the negative pressure flow path 13, improving the suction force and, as a result, allowing dust to be removed efficiently.

[0032] Furthermore, since the cleaning tool 4 is stored in the dust collector 1 with the wiping body 41 facing in the Z direction, a dust collector 1 can be provided in which the cleaning tool 4 can be stored in a space-saving manner and dust can be removed from the wiping body 41.

[0033] (2) The suction port 100a is provided only in the first side wall 100 among the side walls. As a result, the negative pressure at the suction port is more likely to be strong than in the case where suction ports are provided on the other side walls as well.

[0034] (3) A second side wall 101 is one of the side walls defining the storage chamber 10 and faces the first side wall 100. The second side wall 101 has an upper wall portion 101a located on the Z1 side and a lower wall portion 101c located on the Z2 side of the upper wall portion 101a and constituting a guide portion 101b. A distance L2 between the lower wall portion 101c and the first side wall 100 is shorter than a distance L1 between the upper wall portion 101a and the first side wall 100.

[0035] As a result, the lower wall portion 101c functions as the guide portion 101b, making it easier to bring the wiping body 41 into close contact with the first side wall 100. In addition, since the distance L1 between the upper wall portion 101a and the first side wall 100 is relatively long, the wiping body 41 can be easily inserted from the opening 105 of the storage chamber 10.

[0036] In contrast, for example, in the case of a rectangular storage chamber that does not have a guide portion, if the cleaning tool is too small for the opening of the storage chamber, it is difficult to bring the wiping body into close contact with the first side wall compared to the embodiment of the present disclosure. On the other hand, if the cleaning tool is too large for the opening of the storage chamber, it is difficult to insert the cleaning tool compared to the embodiment of the present disclosure. The embodiment of the present disclosure can solve the above problem by providing a guide portion so that the wiping body can easily come into close contact with the first side wall while ensuring the size of the opening.

[0037] (4) The second side wall 101 has a slope portion 101d that slopes toward the first side wall 100 from the lower end of the upper wall portion 101a toward the upper end of the lower wall portion 101c. As a result, the wiping body 41 can be more easily guided toward the first side wall 100 by the slope portion 101d that is inclined toward the first side wall 100 side.

[0038] [Second embodiment] 7 is a cross-sectional view of a dust collector 2 according to a second embodiment of the present disclosure similar to FIG. 3, and omits the dust collecting unit 11 and the negative pressure source 12. Only configurations different from the first embodiment will be described below.

[0039] The storage chamber 10 has a bottom wall 200 that slopes toward the Z2 side toward the first side wall 100 (X1 side).

[0040] The second side wall 101 is provided with a leaf spring (biasing portion) 201 on the upper wall portion 101a. The leaf spring 201 is a flat plate extending in the Y direction. The leaf spring 201 is fixed to the upper wall portion 101a by attaching an upper end portion 201a of the leaf spring 201 to the upper end side (i.e., the opening 105 side) of the upper wall portion 101a by means of bonding or the like. The leaf spring 201 has an upper inclined portion 201c inclined downward from the upper end portion 201a toward the first side wall 100 side, a vertical portion 201d extending from the upper inclined portion 201c to the Z2 side, a lower inclined portion 201e inclined downward from the vertical portion 201d toward the second side wall 101 side, and a lower end portion 201b which is the end portion of the lower inclined portion 201e opposite to the vertical portion 201d. The lower end 201b is not fixed to the upper wall portion 101a. The leaf spring 201 is a typical leaf spring and is made of a metal material such as stainless steel, iron, or copper, or a resin material. The leaf spring 201 is configured as a guide portion 202 of the second embodiment.

[0041] 8 is a cross-sectional view similar to FIG. 3 when the cleaning tool 4 is inserted into the dust collector 2 according to the second embodiment. When the cleaning tool 4 is inserted into the storage chamber 10, the wiping body 41 moves to the Z2 side while contacting the upper inclined portion 201c and / or the vertical portion 201d of the leaf spring 201. As the wiping body 41 moves, the leaf spring 201 is elastically deformed so as to move toward the second side wall 101, so that the elastic force of the leaf spring 201 presses the wiping body 41 toward the first side wall 100. The leaf spring 201 may press the handle 40 toward the first side wall 100, or press the wiping body 41 and the handle 40 toward the first side wall 100, thereby pressing the wiping body 41 toward the first side wall 100. When the tip of the wiping body 41 reaches the bottom wall 200, the wiping body 41 is directed toward the first side wall 100 by the lower wall portion 101c on the Z2 side and by the leaf spring 201 on the Z1 side.

[0042] The dust collector 2 according to this embodiment provides the following effects.

[0043] (1) The guide portion 202 is a biasing portion 201 that biases the wiping body 41 accommodated in the accommodation chamber 10 toward the first side wall 100 side. As a result, the wiping body 41 is urged toward the first side wall 100 by the urging portion 201, so that the wiping body 41 is more likely to come into close contact with the first side wall 100. This further strengthens the negative pressure at the suction port 100a.

[0044] (2) The biasing portion 201 is a leaf spring 201 . As a result, the leaf spring 201 orients the wiping body 41 toward the first side wall 100, and therefore the simple configuration makes it easy to bring the wiping body 41 into close contact with the first side wall 100. In addition, in this embodiment, the leaf spring 201 is provided on the upper wall portion 101b, and therefore the leaf spring 201 and the lower wall portion 101c make it easy to bring the wiping body 41 into close contact with the first side wall 100 evenly in the Z direction.

[0045] (3) The leaf spring 201 has an upper inclined portion 201c that is inclined downward toward the first side wall 100 side. As a result, the wiping body 41 is easily guided toward the first side wall 100. In this embodiment, since the leaf spring 201 further has the vertical portion 201d and the lower inclined portion 201e, when the cleaning tool 4 is moved up and down within the accommodation chamber 10, it is possible to prevent the wiping body 41 from being pinched between the lower end portion 201b of the leaf spring 201 and the first side wall 100.

[0046] (4) The container further includes a bottom wall 200 that defines the storage chamber 10, and the bottom wall 200 is inclined downward toward the first side wall 100. As a result, the dust scraped off from the wiping body 41 can move toward the first side wall 100 according to the inclination of the bottom wall 200, so that the dust can be more efficiently sucked in through the suction port 100a.

[0047] [Third embodiment] Fig. 9 is a cross-sectional view similar to Fig. 3 when the cleaning tool 4 is inserted into the dust collector 3 according to the third embodiment of the present disclosure. Only configurations different from the first and second embodiments will be described below.

[0048] The storage chamber 10 has a partition wall 302 and a protrusion 303 extending in the Z1 direction from the partition wall 302, which separate the storage chamber 10 into an upper space 300 and a lower space 301. The upper space 300 is a space in the storage chamber 10 on the Z1 side of the partition wall 302. The lower space 301 is a space in the storage chamber 10 on the Z2 side of the partition wall 302.

[0049] The partition wall 302 is located at the lower end of the lower wall portion 101c. The partition wall 302 is a flat mesh plate extending in the X and Y directions. The partition wall 302 is fixed to one of the side walls by joining the periphery of the partition wall 302 to one of the side walls. The partition wall 302 prevents the wiping body 41 from passing through the partition wall 302 from the upper space 300 into the lower space 301. The mesh size of the partition wall 302 is a size that allows dust to pass through the mesh, and specifically, the mesh size is 3 mm to 50 mm, more preferably 5 mm to 20 mm.

[0050] The protrusion 303 is a flat plate extending in the Y direction. The protrusion 303 is fixed to the partition wall 302 by joining a lower edge of the protrusion 303 to the partition wall 302. The protrusion 303 guides the wiping body 41 toward the first side wall 100.

[0051] The dust collector 3 according to this embodiment has the following advantages.

[0052] (9) The storage chamber 10 has a mesh partition 302 that separates the storage chamber 10 into the upper space 300 and the lower space 301 and prevents the wiping body 41 from entering the lower space 301. As a result, the mesh partition 302 prevents the wiping body 41 from entering the lower space 301, so that dust that has been scraped off the wiping body 41 and then passed through the partition 302 and is present in the lower space 301 can be prevented from adhering to the wiping body 41 again.

[0053] (10) The accommodation chamber 10 has the protrusion 303 that extends in the Z1 direction from the partition wall 302 and guides the wiping body 41 toward the first side wall 100. As a result, when the wiping body 41 comes into contact with the partition wall 302, the wiping body 41 is guided to the first side wall 100 by the protrusions 303, making it easier to bring the wiping body 41 into close contact with the first side wall 100.

[0054] The dust collector according to the present disclosure is not limited to the configuration of the above embodiment, and various modifications are possible.

[0055] In the leaf spring 201 according to the embodiment of the present disclosure, only the upper end portion 201a is attached to the upper wall portion 101a, but the lower end portion 201b may also be attached to the upper wall portion 101a.

[0056] The biasing portion in the embodiment of the present disclosure is, but is not limited to, the leaf spring 201. For example, the biasing portion may be configured by a combination of a plate and an elastic means such as a coil spring.

[0057] In the embodiment of the present disclosure, the partition wall 302 is located at the lower end of the lower wall portion 101c, but is not limited to this position. The partition wall 302 is preferably provided on the lower wall portion 101c.

[0058] In the embodiment of the present disclosure, the protrusion 303 is provided on the partition 302, but the partition 302 may not be provided with the protrusion 303, and even in this case, the wiping body 41 can be guided toward the first side wall 100.
