Figure 2 It is a top view of the cleaning device 1. Hereinafter, the side on which the cleaning device 1 is placed is defined as the lower side, the opposite side thereof is defined as the upper side, one end side in the long side direction of the cleaning device 1 (the side provided with the insertion port 14) is defined as the left side, and the opposite side thereof is defined as the right side.

[0010] like Figure 1As shown, the cleaning device 1 has a housing 10 for accommodating various structures. The housing 10 is formed in a box shape. In this embodiment, the housing 10 has a shape that is long in a first direction (in this embodiment, a left-right direction) perpendicular to the up-down direction.

[0011] The housing 10 has an upper surface 11, a lower surface 12, and a side surface 13. The upper surface 11 and the lower surface 12 are arranged opposite to each other in the vertical direction. The upper surface 11 and the lower surface 12 are plate-like members that are elongated in the left-right direction. The upper surface 11 and the lower surface 12 are each formed in an arc shape in a manner that each end in the left-right direction is rounded, for example. The side surface 13 is formed so that the outer edge of the upper surface 11 and the outer edge of the lower surface 12 are connected up and down. In the present embodiment, the side surface 13 has a front surface portion 13a as a flat surface, a rear surface portion 13b as a flat surface, a left side surface portion 13c as a curved surface, and a right side surface portion 13d as a curved surface. In addition, the side surface 13 is configured in a manner including a flat surface and a curved surface, but is not limited to this, and may be configured only by a flat surface or only by a curved surface. In addition, the shapes of the upper surface 11 and the lower surface 12 are formed in an arc shape in a manner that each end in the left-right direction is rounded, but is not limited to this, and may also be formed in a circular shape, an elliptical shape, a polygonal shape, etc. in accordance with the shape of the side surface 13.

[0012] The housing 10 has an insertion port 14 provided on the upper surface 11, an inner wall 15 extending downward from the insertion port 14, and a bottom wall 16 opposite to the insertion port 14. The insertion port 14 is an opening for inserting a cleaning tool 100 (cleaning component 120) described later. The insertion port 14 is, for example, a roughly circular opening. The inner wall 15 is a cylindrical wall portion surrounding the axial direction when the up-down direction is the axial direction. The inner wall 15 has an inclined portion 15a and an extension portion 15b, wherein the inclined portion 15a is formed so that the cross-sectional area of ​​the cross section perpendicular to the axial direction becomes smaller as it moves downward from the insertion port 14, and the extension portion 15b extends downward from the inclined portion 15a. The inclined portion 15a is located at the upper portion of the inner wall 15, and is arranged to be inclined inward as it moves downward from the opening edge of the insertion port 14. The extension portion 15b is the main portion of the inner wall 15, and extends downward from the lower end of the inclined portion 15a. The bottom wall 16 is a wall portion that closes the lower end of the inner wall 15. In the present embodiment, the bottom wall 16 is a flat surface. The bottom wall 16 is a flat surface, but is not limited thereto and may also be a curved surface. Figure 6 As shown, the inclination degree of the inclined portion 15a with respect to the horizontal direction is not uniform and different at the left end side and the right end side. For example, the right end side of the inclined portion 15a is more gently inclined than the left end side. In this way, the inclination degree of the inclined portion 15a can also be gradually gentle from the right end side to the left end side. In addition, the inclination degree of the inclined portion 15a with respect to the horizontal direction is different at the left end side and the right end side, but it is not limited to this, and it can also be uniform.

[0013] In the above configuration, the housing 10 has a space S surrounded by the inner wall 15 and the bottom wall 16. The space S is a space into which the cleaning tool 100 (cleaning member 120) can be inserted through the insertion port 14.

[0014] use Figure 3 and Figure 4 , an example of the cleaning tool 100 (cleaning member 120 ) that can be inserted into the space S of the cleaning device 1 will be described. Figure 3 This is a perspective view of the cleaning tool 100 as viewed from the front surface side of the cleaning member 120 . Figure 4 This is a perspective view of the cleaning tool 100 as seen from the back side of the cleaning member 120. The front side of the cleaning member 120 is the side on which the pile 122 is attached to a base fabric 121 described later, and the back side of the cleaning member 120 is the opposite side.

[0015] In the present embodiment, the cleaning tool 100 is a brush used when cleaning or wiping furniture, floors, etc., in other words, a mop. The cleaning tool 100 includes a handle 110 and a cleaning member 120 .

[0016] The handle 110 is a component extending in a rod shape. The handle 110 has a gripping portion 110a for the user to hold and a mounting portion 110b on which the cleaning component 120 is mounted. The gripping portion 110a is a portion formed in a cylindrical shape from one end to the central portion in the long side direction of the handle 110. The mounting portion 110b is a portion formed in a flat rectangular plate shape from the central portion to the other end in the long side direction of the handle 110. In the present embodiment, the gripping portion 110a and the mounting portion 110b of the handle 110 are integrally formed, but are not limited thereto and may also be separately formed. In addition, the gripping portion 110a may also be configured to be variable in length.

[0017] The cleaning member 120 includes a base fabric 121, piles 122 fixed to the base fabric 121, and a base material 123 to which the base fabric 121 is attached. The base fabric 121 is a substantially rectangular cloth. The piles 122 are attached to the surface of the base fabric 121 by various methods such as embedding or weaving. The back of the base fabric 121 is attached to the surface of the base material 123. The base material 123 is a plate-like member having substantially the same shape and size as the base fabric 121.

[0018] The cleaning member 120 (base material 123) is detachably mounted on the handle 110 (mounting portion 110b). The base material 123 and the mounting portion 110b are detachably mounted, for example, by means of a snap-fit ​​structure. A hook constituting a snap-fit ​​is provided on the back of the base material 123, and a ring constituting a snap-fit ​​is provided on the surface of the mounting portion 110b. The back of the base material 123 is mounted in surface contact with the surface of the mounting portion 110b by engaging the hook and the ring. In addition, the base material 123 and the mounting portion 110b are detachably mounted by means of a snap-fit ​​structure, but are not limited thereto, and may be, for example, a sliding mounting structure.

[0019] use Figures 5 to 7 , the internal structure of the cleaning device 1 is described. Figure 5 2 is a perspective view showing the internal structure of the cleaning device 1. Figure 5 In the figure, a part of the side surface 13 is omitted. Figure 6 It is a cross-sectional view showing the internal structure of the cleaning device 1 . Figure 6 yes Figure 2 VI-VI line cross-section diagram. Figure 7 It is an exploded perspective view of the cleaning device 1 .

[0020] The housing 10 has a first suction port 20a and a first blow-out port 20b. A first air passage 20 connecting the first suction port 20a and the first blow-out port 20b is formed inside the housing 10. The first suction port 20a is provided on the inner wall 15, and the first blow-out port 20b is provided on the outer surface of the housing 10 (the rear surface portion 13b in this embodiment). In this embodiment, the first suction port 20a is located above the central portion of the inner wall 15 in the vertical direction.

[0021] The cleaning device 1 further includes a first blower fan 30 (first blower unit), a dust collector 40, and an operation unit 50. The first blower fan 30 and the dust collector 40 are provided on the first air passage 20. The operation unit 50 is provided on the upper surface 11 of the housing 10, for example.

[0022] The first air supply fan 30 is, for example, an electric air supply machine (electric suction machine) having a fan and a motor. The first air supply fan 30 is mounted on a fan box 22 described later via a sound insulation material, vibration-proof rubber, etc. The fan is rotated by driving the motor constituting the first air supply fan 30, thereby generating an air flow from the first suction port 20a to the first blow-out port 20b via the first air passage 20.

[0023] The dust collecting unit 40 collects dust contained in the air flowing in the first air passage 20. The dust collecting unit 40 is, for example, a paper bag. In addition, in the present embodiment, the dust collecting method is a paper bag, but it is not limited thereto, and it may be a cyclone type or a filter type. When the dust collecting method is a cyclone type, the dust collecting unit 40 only needs to be a cyclone dust collector, and when the dust collecting method is a filter type, the dust collecting unit 40 only needs to have a filter and a dust collecting cup.

[0024] The operating unit 50 receives various operations of the cleaning device 1. Various operations refer to, for example, operations related to starting and stopping the operation of the cleaning device 1. The operating unit 50 is, for example, a touch panel, but is not limited thereto, and may also be a physical key. A circuit board 51 is provided below the operating unit 50 in the housing 10.

[0025] The first air passage 20 includes a dust box 21 and a fan box 22. The dust box 21 is arranged on the right side of the space S inside the housing 10. In the present embodiment, the dust box 21 is configured to be divisible up and down. The fan box 22 is arranged on the lower right side of the dust box 21 inside the housing 10. In the present embodiment, the fan box 22 is configured to be divisible left and right. As described above, the space S, the dust box 21, and the fan box 22 are arranged linearly in the first direction (left and right direction) relative to the housing 10 in sequence.

[0026] The dust box 21 includes, for example, a main body 21 a that accommodates the dust collecting portion 40 therein, and a duct 21 b that extends from the main body 21 a toward the first suction port 20 a .

[0027] The main body 21a is formed into a bottomed square tube with the vertical direction as the longitudinal direction. A pipe 21b is provided on the upper part of the main body 21a. One end (the right end in this embodiment) of the pipe 21b is connected to the inside of the main body 21a, and the other end (the left end in this embodiment) is connected to the first suction port 20a via a seal or the like.

[0028] A paper bag is mounted on the main body 21a so as to cover the portion connected to the duct 21b from the inside, which constitutes the dust collecting unit 40. Thus, the dust collecting unit 40 can collect dust contained in the air sucked from the duct 21b. The dust collecting unit 40 is formed of a material that allows air to pass through. An opening 21c is provided on the right side of the lower part of the main body 21a, which is connected to the fan box 22 via a seal or the like.

[0029] The fan case 22 is a case that accommodates the first air supply fan 30. The fan case 22 is formed, for example, in a substantially cylindrical shape with the left-right direction as the axial direction. The fan case 22 has a fan suction port 22a for sucking in air and a fan outlet 22b for blowing out air. The fan suction port 22a is, for example, a plurality of holes formed at the left end of the fan case 22. The fan outlet 22b is, for example, an opening formed on the peripheral surface of the fan case 22.

[0030] The fan inlet 22a of the fan case 22 communicates with the opening 21c of the dust box 21 via a seal etc. Thus, air from which dust has been removed by the dust collecting unit 40 is sucked into the fan case 22 from the fan inlet 22a and blown out into the housing 10 from the fan outlet 22b.

[0031] By providing the first outlet 20b on the side surface 13 of the housing 10, more specifically, on the rear surface portion 13b located behind the fan outlet 22b, the air blown out from the fan outlet 22b passes through the inside of the housing 10 and is discharged from the first outlet 20b to the outside of the housing 10. In addition, a duct connecting the fan outlet 22b and the first outlet 20b may be provided. In this case, the air discharged from the fan outlet 22b will not be blown into the inside of the housing 10, and the air heated by the motor heat of the first air supply fan 30 will not be blown into the housing 10, so that the temperature rise in the housing 10 can be reduced.

[0032] The housing 10 has a second air inlet 23a and a second air outlet 23b. A second air passage 23 is formed inside the housing 10 to communicate with the second air inlet 23a and the second air outlet 23b. The second air inlet 23a is provided on the outer surface of the housing 10 (in this embodiment, the front surface 13a) (see Figure 1 and Figure 7 ). The second blowing outlet 23b is provided on the inner wall 15. Specifically, the second blowing outlet 23b is provided on the inner wall 15 below the first suction port 20a, and is provided on the inner wall 15 on the same side (right side) as the side on which the first suction port 20a is provided. In the present embodiment, the second blowing outlet 23b is located below the central part in the up-down direction of the inner wall 15. In addition, the second suction port 23a may also be provided on the rear surface portion 13b. In this way, when observed from the front, the user cannot see the first blowing outlet 20b and the second suction port 23a, so the aesthetics is improved.

[0033] The cleaning device 1 further includes a second blower fan 60 (second blower unit) and an ion generator 70 . The second blower fan 60 and the ion generator 70 are provided in the second air passage 23 .

[0034] The second air supply fan 60 is, for example, an electric blower having a fan and a motor. By driving the motor constituting the second air supply fan 60 to rotate the fan, an air flow is generated from the second air inlet 23a to the second air outlet 23b via the second air passage 23. The second air supply fan 60 is a small air supply fan having a small rated output of the motor compared to the first air supply fan 30. Preferably, the small air supply fan has less noise than the first air supply fan 30 when driven. In the present embodiment, the housing 10 is configured to have the second air inlet 23a, but is not limited thereto, and the second air inlet 23a may also be omitted. In this case, the second air supply fan 60 inhales the air inside the housing 10, and generates an air flow toward the second air outlet 23b via the second air passage 23. The air inside the housing 10 here is the air blown out from the fan outlet 22b of the first air supply fan 30 to the inside of the housing 10, or the air inhaled from the first air outlet 20b by the second air supply fan 60 when the driving of the first air supply fan 30 is stopped.

[0035] The ion generating unit 70 generates ions by, for example, discharge. Specifically, the ion generating unit 70 generates discharge by applying a high voltage to the needle-shaped discharge electrode 70a, thereby releasing ions. The ion generating unit 70 is, for example, disposed in the second air passage 23. Specifically, the needle-shaped discharge electrode 70a is configured to be exposed from the upper wall of the duct member 24 described later to the inside. The discharge electrode 70a has a positive discharge electrode that generates positive ions and a negative discharge electrode that generates negative ions. The positive discharge electrode and the negative discharge electrode are arranged at a predetermined interval in the left-right direction. The air flowing through the second air passage 23 is blown out from the second blow-out port 23b to the space S by adding the positive ions and negative ions generated by the ion generating unit 70, for example, deodorization or static electricity suppression, sterilization or proliferation suppression of mold, etc. in the space S can be performed. In addition, ions are an example of charged particles, and the ion generating unit 70 is an example of a charged particle supply (generation) mechanism that supplies (generates) charged particles.

[0036] Charged particles refer to non-neutral particles and active species activated in a non-neutral state. Charged particles are not limited to particles with electric charge, for example, also include particles such as atoms and molecules that have no charge but have unpaired electrons. Specifically, charged particles include, for example, ions with positive or negative charge, complexes of ions with positive or negative charge, free radicals, electrons, protons, etc. The charged particle supply (generation) mechanism can be, for example, a mechanism that supplies (generates) only one type of charged particles, or a mechanism that supplies (generates) multiple types of charged particles. The charged particle supply (generation) mechanism can be, for example, a mechanism that supplies (generates) both positive ions or complexes of positive ions (for example, complexes in which polar molecules such as water molecules are coordinated to positive ions) and negative ions or complexes of negative ions (for example, complexes in which polar molecules such as water molecules are coordinated to negative ions). The charged particle supply (generation) mechanism can also, for example, only supply (generate) one of the complexes of positive ions and negative ions.

[0037] The second air passage 23 is, for example, provided independently of the first air passage 20. The second air passage 23 includes a duct member 24 and a fan box 25. The duct member 24 is arranged on the right side of the space S inside the housing 10, and is arranged on the lower side of the dust box 21. One end of the duct member 24 is connected to the second blow-out port 23b, and the other end is connected to the fan box 25. The duct member 24 extends to the left from the fan box 25, and then extends obliquely upward toward the second blow-out port 23b. The ion generating unit 70 is mounted on the upper wall of the duct member 24, but is not limited thereto, and may also be mounted on the lower wall or the side wall of the duct member 24.

[0038] The fan box 25 is a box body that accommodates the second air supply fan 60. The fan box 25 has a fan suction port (not shown) for sucking in air and a fan outlet (not shown) for blowing out air. The fan outlet of the fan box 25 is connected to the other end of the duct member 24 via a seal or the like. A second suction port 23a is provided near the fan suction port of the fan box 25, specifically, on the front surface portion 13a of the housing 10 located in front of the fan box 25. Thus, the air sucked in from the second suction port 23a can be introduced into the fan box 25.

[0039] In the above configuration, the flow of air in the cleaning device 1 will be described.

[0040] First, the flow of air introduced into the first air passage 20 will be described. By driving the first air supply fan 30, the air introduced into the space S from the insertion port 14 is sucked into the first air passage 20 from the first suction port 20a. Then, the air passes through the dust collecting box 21, and dust contained in the air is collected by the dust collecting unit 40. The air from which dust is removed passes through the fan box 22 and is blown out from the first blowing port 20b of the housing 10 to the outside of the housing 10.

[0041] Next, the flow of the air introduced into the second air passage 23 will be described. By driving the second air supply fan 60, the air sucked from the second suction port 23a passes through the fan box 25 and the duct member 24, and is blown out from the second blow-out port 23b to the space S together with the positive ions and negative ions generated by the ion generating unit 70. The air blown into the space S with the positive ions and negative ions added thereto is blown out along the space S, for example, Figure 8 After flowing in the direction of the arrow shown, the air is sucked into the first air passage 20 from the first suction port 20 a or is blown out to the outside of the housing 10 from the insertion port 14 .

[0042] The operation of the cleaning device 1 is described below. For example, the user operates the operating unit 50 to start the operation of the cleaning device 1. When the operation of the cleaning device 1 starts, the control unit (not shown) drives the first air supply fan 30 for a specified time. Then, when the control unit stops driving the first air supply fan 30 after a specified time, it drives the second air supply fan 60 for a specified time. Furthermore, if the control unit stops driving the second air supply fan 60 after a specified time, the operation of the cleaning device 1 ends. In the above operation of the cleaning device 1, the time for driving the first air supply fan 30 is shorter than the time for driving the second air supply fan 60. In addition, in the above description, the control unit drives the first air supply fan 30 and the second air supply fan 60 at staggered timings, but is not limited to this. The control unit may also drive the first air supply fan 30 and the second air supply fan 60 at the same time. When the control unit drives the first air supply fan 30 and the second air supply fan 60 simultaneously, air with positive ions and negative ions added thereto is sucked into the dust collecting section 40, thereby achieving effects such as deodorization, static electricity suppression, and fungal sterilization and growth suppression in the dust collecting section 40.

[0043] Below, use Figures 8 to 10 , cleaning using the cleaning tool 100 (cleaning member 120) of the cleaning device 1 will be described. Figure 8 1 is a cross-sectional view showing the cleaning device 1 in a state where the cleaning member 120 is inserted into the space S. FIG. Fig. 9 1 is a plan view showing the cleaning device 1 in the space S. Fig. 9 yes Figure 2 A partial enlarged view of . Fig.10 It is a cross-sectional view of the cleaning device 1 showing the first suction port 20a. Fig.10 yes Figure 2 XX line cross section.

[0044] like Figure 8As shown, the cleaning tool 100 is inserted in a direction in which the cleaning component 120 is opposite to the first suction port 20a formed on the inner wall 15. The inner wall 15 constituting the space S has: an inclined portion 15a, the cross-sectional area of ​​which becomes larger as it goes upward in a cross-sectional area perpendicular to the axial direction; and an extension portion 15b, the cross-sectional area of ​​which is substantially constant. The inclined portion 15a is formed in a tapered shape in such a manner that the cross-sectional area becomes larger as it goes upward, thereby facilitating the insertion of the cleaning component 120 into the space S. In addition, since the inner wall 15 has the inclined portion 15a, when the cleaning component 120 is inserted into the space S from the insertion port 14, even if the fluff 122 is rubbed against the inclined portion 15a, it is possible to suppress dust attached to the fluff 122 from falling. In addition, the degree of inclination of the inclined portion 15a relative to the horizontal direction is uneven and different at the left end side and the right end side, such as Figure 6 As shown, the right end of the inclined portion 15a is more gently inclined than the left end. By adopting such a structure, when the user inserts the cleaning member 120 into the space S, it can be used as a mark for inserting the fluff 122 in the correct direction (direction opposite to the first suction port 20a).

[0045] like Fig. 9 As shown, the stretching portion 15b is formed into a roughly elliptical shape when viewed from above, and a part of it (the right side portion in this embodiment) has the same shape as the outer shape of the cleaning component 120. The outer shape of the cleaning component 120 is the shape of the front end of the fluff 122 that constitutes the cleaning component 120 when viewed from above. In the present embodiment, the outer shape of the cleaning component 120 has a shape in which a part of the circumference of the ellipse is cut off, but is not limited to this. For example, it can be a shape in which a part of the circumference of a circle is cut off, or it can be a flat flat shape. In addition, the first suction port 20a is formed in the portion (right side portion) of the extension portion 15b having a shape roughly the same as the outer shape of the cleaning component 120. Thereby, it is easy to make the direction when inserting the cleaning tool 100 the direction opposite to the first suction port 20a.

[0046] In the above configuration, by driving the first air supply fan 30, the cleaning component 120 is moved back and forth in the vertical direction relative to the space S, so that the air containing dust attached to the surface of the cleaning component 120 can be sucked in from the first suction port 20a, and the dust contained in the air can be removed by the dust collecting unit 40.

[0047] like Figure 8As shown, when the cleaning member 120 is inserted into the bottom wall 16, the upper end of the first suction port 20a formed in the inner wall 15 is located above the upper end of the cleaning member 120. In addition, in the present embodiment, the upper end of the first suction port 20a is located above the upper end of the cleaning member 120, but it is not limited thereto, and the upper end of the first suction port 20a may also be located at the same position as the upper end of the cleaning member 120. The state in which the cleaning member 120 is inserted into the bottom wall 16 refers to a state in which the lower end of the cleaning member 120 contacts the bottom wall 16, or a state in which the lower end of the cleaning member 120 contacts the bottom wall 16 and the cleaning member 120 cannot be further pressed downward. Thus, when the cleaning member 120 is moved upward relative to the space S, the entire cleaning member 120 can be made to face the first suction port 20a from the upper end to the lower end of the cleaning member 120. Likewise, even when the cleaning member 120 is moved downward relative to the space S, the entire cleaning member 120 from the lower end to the upper end can be made to face the first suction port 20a. Therefore, the dust attached to the cleaning member 120 can be reduced from being scattered.

[0048] like Fig. 9 and Fig.10 As shown, the housing 10 has a pair of protrusions 17 protruding inward from the inner wall 15 toward the space S. The pair of protrusions 17 are arranged opposite to each other at intervals in the up-down direction. Each protrusion 17 is a plate-shaped member having a thickness in the up-down direction. The upper surface and the lower surface of each protrusion 17 are respectively flat surfaces. The front end surface of each protrusion 17 has a shape that is substantially the same as the outer shape of the cleaning member 120. That is, the front end surface of each protrusion 17 has a shape in which a part of the circumference of an ellipse is cut off when viewed from above.

[0049] like Fig.10 As shown, a first suction port 20a is provided between a pair of protrusions 17 in the inner wall 15. The first suction port 20a has a shape in which a circular opening is cut into a rectangular shape toward the left and right outer sides. A pair of protrusions 17 are provided in a manner that sandwiches the first suction port 20a. In the present embodiment, the protrusions 17 are provided at intervals in the up and down directions relative to the first suction port 20a, but are not limited thereto. As long as they are provided in a manner that sandwiches the first suction port 20a, the protrusion 17 located on the upper side may also be provided in a manner that protrudes inwardly from the opening edge portion on the upper side constituting the first suction port 20a, and the protrusion 17 located on the lower side may also be provided in a manner that protrudes inwardly from the opening edge portion on the lower side constituting the first suction port 20a.

[0050] As described above, by providing the first suction port 20a between the pair of protrusions 17 of the inner wall 15, the pair of protrusions 17 function as a wall portion (guide portion) for sucking air into the first suction port 20a, so that dust and the like attached to the cleaning member 120 opposite to the first suction port 20a can be effectively sucked in. Therefore, the cleaning performance of the cleaning member 120 can be improved.

[0051] In the present embodiment, the protrusion 17 is arranged up and down across the first suction port 20a, but is not limited thereto, and may also be arranged in a manner to surround the first suction port 20a. That is, it may also be formed in a manner to connect the left and right ends of a pair of protrusions 17 to each other. As described above, by arranging the protrusion 17 in a manner to surround the first suction port 20a, the protrusion 17 functions as a wall portion (guide portion) for sucking air into the first suction port 20a, similarly to the above, so that dust attached to the cleaning component 120 opposite to the first suction port 20a can be effectively sucked in. Therefore, the cleanability of the cleaning component 120 can be improved.

[0052] In addition, when the cleaning member 120 is moved back and forth in the vertical direction relative to the space S, the cleaning member 120 (pile 122) contacts the front end faces of the pair of protrusions 17, whereby the front end faces of the protrusions 17 play a role in scraping off dust and the like attached to the cleaning member 120 (pile 122), thereby improving the cleaning performance of the cleaning member 120. From the viewpoint of effectively scraping off dust and the like attached to the cleaning member 120, the front end face of the protrusion 17 preferably has the same shape as the outer shape of the cleaning member 120. In addition, by the protrusion 17 located on the lower side protruding toward the inner side of the space S, the dust attached to the cleaning member 120 is easily scraped off at the front of the first suction port 20a, and the cleaning efficiency is improved. In addition, the protrusion 17 located on the lower side may also protrude from the inner wall 15 The length of the protrusion 17 located on the upper side from the inner wall 15 can also be greater than the length of the protrusion 17 located on the upper side from the inner wall 15. In this case, it is preferred that the protrusion 17 located on the upper side is set to a degree that a small gap is formed with respect to the cleaning member 120 (fluff 122), and the protrusion 17 located on the lower side is brought into contact with the cleaning member 120 (fluff 122). In this way, the dust scraped off by the protrusion 17 located on the lower side can be sucked into the first suction port 20a by the wind sucked from the gap formed between the protrusion 17 located on the upper side and the cleaning member 120, and the undesirable situation that dust falls on the upper side of the protrusion 17 located on the upper side can be reduced.

[0053] In the present embodiment, when the first suction port 20a is observed from the front, that is, from the opening direction (left and right direction in the present embodiment), it has a shape in which the circular opening portion is cut into a rectangular shape toward the left and right outer sides, but is not limited to this, for example, it can also be rectangular, circular, elliptical, etc.

[0054] Below, use Fig.11 A modification example of the first suction port 20a will be described. Fig.11 It is a cross-sectional view of the cleaning device 1 showing a modified example of the first suction port 20a.

[0055] like Fig.11 As shown, the first air inlet 20a is rectangular when viewed from the front. In other words, the cross-sectional shape of the first air inlet 20a perpendicular to the opening direction (the left-right direction in this embodiment) is rectangular. The first air inlet 20a is arranged in such a way that the opening edge of the first air inlet 20a protrudes inward toward the space S. Fig.11 In the modified example shown, the upper wall and the lower wall constituting the first suction port 20a (opening edge) preferably have a front end surface having a shape substantially the same as the outer shape of the cleaning member 120. That is, the front end surface of the first suction port 20a preferably has a shape obtained by cutting off a portion of the circumference of an ellipse when viewed from above. Fig.11 In the modified example shown, since the upper wall and the lower wall constituting the first suction port 20a can play the role of the protrusion 17, the protrusion 17 can also be omitted. Fig.11 The opening area of ​​the first suction port 20a of the modified example shown can be larger than Fig.10 The opening area of ​​the first suction port 20a of the embodiment shown is small, so the wind speed can be increased at the first suction port 20a. Therefore, dust and the like attached to the cleaning member 120 can be more effectively sucked in, so the cleaning performance of the cleaning member 120 can be improved. Fig.11 In the modified example shown, similarly to the above-described embodiment, a configuration can be applied in which the upper end of the first suction port 20a is located at the same position as the upper end of the cleaning member 120 or is located above the upper end of the cleaning member 120. In addition, as described above, a configuration can be applied in which the protruding length of the lower wall constituting the first suction port 20a from the inner wall 15 is greater than the protruding length of the upper wall constituting the first suction port 20a from the inner wall 15.

[0056] In addition, the housing 10 has a shape that is long in the first direction (the left-right direction in this embodiment), and by arranging the space S, the dust collecting unit 40, and the first air supply fan 30 in the first direction, the thickness of the housing 10 in the front-to-back direction can be reduced, and the height of the housing 10 can be suppressed. Therefore, when the housing 10 is placed on a table, a shelf, etc., there is no sense of oppression, and convenience can be improved.

[0057] In addition, by providing the second blowing outlet 23b that blows out air and ions (for example, positive ions and negative ions) together in the space S, ions (for example, positive ions and negative ions) can be released into the space S, so that effects such as deodorization, static electricity suppression, sterilization of mold, and growth suppression can be expected in the space S. In addition, since ions (for example, positive ions and negative ions) can be released to the cleaning component 120 inserted into the space S, the cleaning component 120 can be de-staticized.

[0058] Furthermore, by arranging the second blowing outlet 23b at a position lower than the first suction port 20a in the space S, it is possible to expect the effects of deodorization or static electricity suppression, sterilization or growth suppression of mold, etc. on the dust and the like that is not sucked in from the first suction port 20a in the space S and falls into the space S. Moreover, when the air blown out from the second blowing outlet 23b is sucked in from the first suction port 20a via the space S, ions (such as positive ions and negative ions) can be released into the dust collecting section 40 together with the air, so it is possible to expect the effects of deodorization, static electricity suppression, sterilization, growth suppression of mold, etc. on the dust collecting section 40 and the dust and the like collected by the dust collecting section 40.

[0059] In addition, ribs R for adjusting the flow in the up-down direction are provided above and below the first suction port 20a of the inner wall 15. The ribs R are plate-shaped components that protrude inward from the inner wall 15 and extend in the up-down direction. A plurality of ribs R are provided along the circumferential direction of the inner wall 15. In the present embodiment, four ribs are provided. As described above, by providing the ribs R, the flow of the air inhaled from the insertion port 14 and the air blown out from the second blow-out port 23b can be adjusted to flow easily in the up-down direction. In the present embodiment, since the ribs R are provided on the second blow-out port 23b side of the inner wall 15 (the right side in the present embodiment), the air blown out from the second blow-out port 23b and the ions can flow easily along the ribs R. Moreover, since the ribs R are opposite to the fluff 122 side of the cleaning component 120, the ions contained in the air flowing along the ribs R can effectively remove the charge on the fluff 122, and the dust attached to the fluff 122 can be easily removed. In addition, effects such as deodorization, sterilization of mold, and inhibition of growth of the fluff 122 can be expected.

[0060] In addition, the second air passage 23 is provided independently from the first air passage 20, but is not limited thereto, and may be configured as a branch passage branching from the first air passage 20. In this case, the second air passage 23 is configured as a branch passage branching from the first air passage 20 by connecting the duct member 24 with a part of the fan outlet 22b. Thus, by driving the first air supply fan 30, a part of the air flowing in the first air passage 20 via the first suction port 20a can be blown out from the second outlet 23b via the duct member 24 together with the ions. In this case, the remaining part of the air flowing through the first air passage 20 is discharged from the first outlet 20b to the outside of the housing 10 via the fan outlet 22b not connected to the duct member 24. In such a configuration, the second air supply fan 60 may also be omitted.

[0061] Below, use Fig.12 The storage portion 18 will be described. The storage portion 18 includes the bottom wall 16 of the space S and stores dust in the space S. The storage portion 18 includes a portion of the outer surface of the housing 10 (in this embodiment, the left side surface portion 13c and the rear surface portion 13b). Fig.12 It is a perspective view showing a state where the storage portion 18 is removed from the housing 10 .

[0062] like Fig.12 As shown, the storage portion 18 is detachably provided with respect to the housing 10. The storage portion 18 is provided with a gripping portion 18a for grasping the storage portion 18 from the outside of the housing 10. The gripping portion 18a is formed to be recessed downward from the rear surface portion 13b of the housing 10. The storage portion 18 is removed from the housing 10 by the user grasping the gripping portion 18a and pulling it out to the rear of the housing 10. Thus, dust and the like that is not sucked in from the first suction port 20a in the space S and falls into the space S can be taken out to the outside of the housing 10, thereby improving convenience.

[0063] Below, use Fig.13 The attachment and detachment of the dust collecting unit 40 will be described. Fig.13 It is a perspective view showing a state where the upper cover 19 b of the housing 10 is opened.

[0064] like Fig.13As shown, the housing 10 has an opening 19a formed on the upper surface 11 and an upper cover 19b capable of opening and closing the opening 19a. The opening 19a is formed on the upper surface 11 of the housing 10 and is connected to the dust box 21. The left end of the upper cover 19b is rotatably arranged relative to the opening 19a, so that it can be rotated to a state of closing the opening 19a and a state of opening the opening 19a. By arranging a seal between the upper cover 19b and the opening 19a, the upper cover 19b hermetically seals the opening 19a in a state of closing the opening 19a. On the upper surface 11 of the housing 10, a recess 19c for rotating the upper cover 19b upward is provided at a position adjacent to the right end of the upper cover 19b. By placing a finger on the recess 19c and lifting the right end of the upper cover 19b upward, the upper cover 19b rotates upward, and the opening 19a becomes an open state.

[0065] like Fig.13 As shown, the dust collecting unit 40 can be entered through the opening 19a when the upper cover 19b of the housing 10 is opened. Thus, the paper bag constituting the dust collecting unit 40 can be loaded and unloaded through the upper cover 19b, so the paper bag constituting the dust collecting unit 40 can be easily replaced.

[0066] In the above configuration, the cleaning device 1 for the cleaning tool 100 is a cleaning device 1 for cleaning the cleaning tool 100 including the handle 110 and the cleaning member 120, and includes: a housing 10 having a first suction port 20a and a first blow-out port 20b; a first air supply unit (first air supply fan 30) for delivering air from the first suction port 20a to the first blow-out port 20b; and a dust collecting unit 40 for collecting dust contained in the air sucked from the first suction port 20a. The housing 10 has an insertion port 14 provided on the upper surface 11, an inner wall 15 extending downward from the insertion port 14, and a bottom wall 16 opposite to the insertion port 14, and the cleaning member 120 can be inserted into the space S surrounded by the inner wall 15 and the bottom wall 16 through the insertion port 14. The first suction port 20 a is provided on the inner wall 15 , and when the cleaning member 120 is inserted into the bottom wall 16 , the upper end of the first suction port 20 a is located at the same position as or above the upper end of the cleaning member 120 .

[0067] Thus, when the cleaning member 120 is moved upward relative to the space S, the cleaning member 120 can be directed toward the first suction port 20a from the upper end to the lower end of the cleaning member 120. Similarly, when the cleaning member 120 is moved downward relative to the space S, the cleaning member 120 can be directed toward the first suction port 20a from the lower end to the upper end of the cleaning member 120. Therefore, the dust attached to the cleaning member 120 can be reduced from falling.

[0068] The housing 10 has a pair of protrusions 17 that protrude from the inner wall 15 toward the space S and face each other at a distance in the up-down direction. The first suction port 20a is provided between the pair of protrusions 17 on the inner wall 15. Thus, since the pair of protrusions 17 function as guides for sucking air into the first suction port 20a, dust and the like attached to the cleaning member 120 that faces the first suction port 20a can be effectively sucked in. Therefore, the cleaning performance of the cleaning member 120 can be improved.

[0069] The front end surface of each protrusion 17 has the same shape as the outer shape of the cleaning member 120. Thus, dust and the like attached to the cleaning member 120 can be efficiently scraped off.

[0070] The first suction port 20a is rectangular, and the front end surfaces of the upper wall and the lower wall of the first suction port 20a are the same shape as the outer shape of the cleaning member 120. Thus, dust and the like attached to the cleaning member 120 can be efficiently scraped off.

[0071] The housing 10 has a long shape in a first direction (left-right direction) orthogonal to the up-down direction, and the space S, the dust collecting part 40, and the first air supply part (first air supply fan 30) are arranged in the first direction (left-right direction). As a result, the thickness of the housing 10 in the front-back direction can be reduced, and the height of the housing 10 can be suppressed. Therefore, when the housing 10 is placed on a table, a shelf, etc., there is no sense of oppression, and convenience can be improved.

[0072] The air conditioner further includes an ion generating unit 70 that generates ions by discharge, and a second air supply unit (second air supply fan 60) that delivers the air sucked in from the second suction port 23a provided in the housing 10 together with the ions toward the second blow-out port 23b provided in the housing 10. The second blow-out port 23b is provided on the inner wall 15. Thus, since ions can be released toward the space S, effects such as deodorization or static electricity suppression, sterilization or growth suppression of mold in the space S can be expected.

[0073] The second blow-out port 23b is provided at a position lower than the first suction port 20a on the inner wall 15. Thus, it is expected that the dust and the like which are not sucked in from the first suction port 20a and fall into the space S can be deodorized or electrostatically suppressed, and the effects of sterilizing or inhibiting the growth of mold can be expected. Moreover, when the air blown out from the second blow-out port 23b is sucked in from the first suction port 20a via the space S, ions can be released into the dust collecting section 40 together with the air, so it is expected that the dust and the like collected in the dust collecting section 40 can be deodorized or electrostatically suppressed, and the effects of sterilizing or inhibiting the growth of mold can be expected.

[0074] The housing 10 includes a bottom wall 16 of the space S, and has a storage portion 18 for storing dust in the space S. The storage portion 18 is detachably provided with respect to the housing 10 . Thus, dust or the like that is not sucked from the first suction port 20a in the space S and falls into the space S can be taken out to the outside of the casing 10, thereby improving convenience.

[0075] The housing 10 has an opening 19a formed on the upper surface 11 and an upper cover 19b that can open and close the opening 19a. When the opening 19a of the housing 10 is opened by the upper cover 19b, the dust collecting section 40 can be entered through the opening 19a. Thus, the paper bag constituting the dust collecting section 40 can be loaded and unloaded through the upper cover 19b, so the paper bag constituting the dust collecting section 40 can be easily replaced.

[0076] In addition, the present invention is not limited to the above-mentioned embodiment, and various deformations can be performed. For example, it can be replaced with a structure substantially the same as the structure shown in the above-mentioned embodiment, a structure having the same effect, or a structure capable of achieving the same purpose. In addition, several or all of the embodiments of the present invention can also be used in combination.
