[0002] There is known an electric vacuum cleaner device including an electric vacuum cleaner and a station for mounting the electric vacuum cleaner. The station recovers dust accumulated in the electric vacuum cleaner into a dust bag stored in the station.

[0003] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2021-078685

[0004] A dust bag is stored in a storage chamber of the station. In the storage chamber, an air inlet and an air outlet are arranged linearly. Air is introduced into the dust bag from the air inlet and is sucked by an electric blower through the air outlet. Therefore, it is difficult for the air flow to fully open the dust bag, and dust tends to accumulate at the bottom of the dust bag near the air outlet. Even when only a small amount of dust is accumulated in the dust bag, the dust accumulated at the bottom of the dust bag near the air outlet sometimes causes clogging. Summary of the Utility Model

[0005] An example of the problem to be solved by the present utility model is to provide an electric vacuum cleaner device capable of using the entire dust bag.

[0006] An electric vacuum cleaner device according to an embodiment of the present utility model includes: an electric vacuum cleaner having: a suction port body; a first electric blower that sucks air containing dust through the suction port body; a first dust collection unit that accumulates the dust contained in the air sucked by the first electric blower; and a storage battery that supplies power to the first electric blower; and a station having: a bracket that holds the electric vacuum cleaner so as to be detachable; a communication pipe that communicates with the first dust collection unit when the electric vacuum cleaner is held by the bracket; a second electric blower that sucks air containing the dust from the first dust collection unit through the communication pipe; and a second dust collection unit that accumulates the dust contained in the air sucked by the second electric blower in a dust bag. The second dust collection unit is provided with a storage chamber for storing the dust bag, an air inlet that opens into the storage chamber and communicates with the first dust collection unit through the communication pipe, and an air outlet that opens into the storage chamber at a position below the air inlet. The second dust collection unit holds the dust bag in such a manner that the dust bag communicates with the air inlet, and the second electric blower sucks the air in the storage chamber through the air outlet. The air inlet is closer to an end of the storage chamber in a first direction than an end of the storage chamber in a second direction opposite to the first horizontal direction, and the air outlet is closer to the end of the storage chamber in the second direction than the end of the storage chamber in the first direction.

[0007] In addition, in the electric vacuum cleaner device of the present embodiment, for example, the second dust collection unit may be provided with a replacement opening that communicates the end of the storage chamber in the first direction with the outside of the station and through which the dust collection bag can pass, and a lid that can be detachably plugged into the replacement opening.

[0008] In addition, in the electric vacuum cleaner device of the present embodiment, for example, the dust collection bag may have a bag-shaped filter medium and a support frame attached to the filter medium. The support frame is closer to the end of the filter medium in the first direction than to the end of the filter medium in the second direction, and the second dust collection unit holds the support frame obliquely so that the end of the filter medium in the second direction approaches the exhaust port.

[0009] In addition, in the electric vacuum cleaner device of the present embodiment, for example, the intake port may face a direction closer to the first direction than the vertically downward direction.

[0010] In addition, in the electric vacuum cleaner device of the present embodiment, for example, the second dust collection unit may have a plurality of ribs provided at the end of the storage chamber in the second direction and extending perpendicularly and parallel to the end.

[0011] In addition, in the electric vacuum cleaner device of the present embodiment, for example, the second electric blower may be provided with a suction port that faces the exhaust port and sucks air.

Detailed implementation mode

[0021] Hereinafter, with reference to Figures 1 to 5 One implementation mode will be described. In addition, in this specification, the vertically upward direction is basically defined as the upward direction, and the vertically downward direction is defined as the downward direction. Furthermore, in this specification, the constituent elements of the implementation mode and the description of the element are sometimes described in multiple expressions. The constituent element and its description are an example and are not limited by the expressions in this specification. The constituent element can also be determined by a name different from the name in this specification. In addition, the constituent element can also be described by an expression different from the expression in this specification.

[0022] In the following description, "suppress" is defined, for example, as preventing the occurrence of an event, action or influence, or reducing the degree of an event, action or influence. In addition, in the following description, "restrict" is defined, for example, as preventing movement or rotation, or allowing movement or rotation within a specified range and preventing movement or rotation exceeding the specified range.

[0023] Figure 1 It is a perspective view showing the electric vacuum cleaner device 10 of this implementation mode. As Figure 1 shown, the electric vacuum cleaner device 10 has an electric vacuum cleaner 11 and a station 12. The station 12 may also be referred to as a dust station or a docking station.

[0024] As shown in the respective drawings, in this specification, for convenience, the X-axis, Y-axis, and Z-axis are defined. The X-axis, Y-axis, and Z-axis are orthogonal to each other. The X-axis is set along the lateral width of the station 12. The Y-axis is set along the front-rear width of the station 12. The Z-axis is set along the height of the station 12.

[0025] Furthermore, in the present specification, the X direction (lateral width direction), the Y direction (front-rear width direction), and the Z direction (vertical direction) are defined. The X direction is the direction along the X axis, including the +X direction (right direction) indicated by the arrow of the X axis, and the -X direction (left direction), which is the opposite direction of the arrow of the X axis. The -X direction is a horizontal direction and is an example of the first direction. The +X direction is the opposite direction of the -X direction and is an example of the second direction. The Y direction is the direction along the Y axis, including the +Y direction (rear direction) indicated by the arrow of the Y axis, and the -Y direction (front direction), which is the opposite direction of the arrow of the Y axis. The Z direction is the direction along the Z axis, including the +Z direction (upward direction) indicated by the arrow of the Z axis, and the -Z direction (downward direction), which is the opposite direction of the arrow of the Z axis.

[0026] The electric vacuum cleaner 11 of the present embodiment is a so-called rod-shaped (upright) electric vacuum cleaner. Additionally, the electric vacuum cleaner 11 is not limited to this example. The electric vacuum cleaner 11 includes a vacuum cleaner main body 21, a suction port body 22, an extension pipe 23, and a storage battery 24. Additionally, the electric vacuum cleaner 11 is not limited to this example. The suction port body 22 may also be referred to as the head.

[0027] Figure 2 is a cross-sectional view showing the electric vacuum cleaner device 10 of the present embodiment. As Figure 2 shown, the vacuum cleaner main body 21 includes a vacuum cleaner housing 31, a first electric blower 32, a first dust collection part 33, and a plurality of switches 34.

[0028] The vacuum cleaner housing 31 is formed in a substantially cylindrical shape. A main body opening 41 is provided at one end of the vacuum cleaner housing 31. A handle 43 is provided at the other end of the vacuum cleaner housing 31. The handle 43 is bent, for example.

[0029] The first electric blower 32 is housed in the vacuum cleaner housing 31. The first electric blower 32 is driven by electricity. The first electric blower 32 generates negative pressure and sucks air from the main body opening 41.

[0030] The first dust collection part 33 is provided in the vacuum cleaner housing 31. Additionally, the first dust collection part 33 may also be detachable from the vacuum cleaner main body 21. The first dust collection part 33 separates dust contained in the air sucked by the first electric blower 32 from the air through a filter, for example. Additionally, the first dust collection part 33 is not limited to this example.

[0031] A dust collection chamber 45 and a discharge port 46 are provided in the first dust collection part 33. Additionally, a plurality of dust collection chambers 45 and a plurality of discharge ports 46 may also be provided in the first dust collection part 33. The dust collection chamber 45 and the discharge port 46 are closer to the main body opening 41 than the first electric blower 32, for example.

[0032] The dust separated from the air in the first dust collection unit 33 falls due to gravity, for example, and accumulates in the dust collection chamber 45. That is, the first dust collection unit 33 accumulates the dust contained in the air attracted by the first electric blower 32. Alternatively, the first dust collection unit 33 may accumulate the dust by the dust adhering to the filter.

[0033] The discharge port 46 communicates the dust collection chamber 45 with the outside of the vacuum cleaner 11. The first dust collection unit 33 has a valve 47. The valve 47 is a lid that can open and close to block the discharge port 46. The valve 47 can be opened toward the outside.

[0034] When the first electric blower 32 attracts air, a negative pressure is generated in the dust collection chamber 45. This negative pressure attracts the valve 47 and keeps the valve 47 in a state of closing the discharge port 46. Alternatively, the valve 47 may be kept in a state of closing the discharge port 46 by a hook or a magnet, for example.

[0035] The switch 34 is provided near the handle 43, for example. By the user operating the switch 34, the first electric blower 32 is driven. Alternatively, the first electric blower 32 may be automatically driven according to specified conditions, for example.

[0036] The suction port body 22 communicates with the main body opening 41 of the vacuum cleaner main body 21 through the extension pipe 23. That is, one end of the extension pipe 23 is connected to the suction port body 22, and the other end of the extension pipe 23 is connected to the main body opening 41. The first electric blower 32 attracts the air containing dust through the suction port body 22 and the extension pipe 23. The suction port body 22 may have various components such as a brush.

[0037] The suction port body 22 may be directly connected to the main body opening 41. In addition, the first electric blower 32 may attract air from the main body opening 41 in a state where neither the suction port body 22 nor the extension pipe 23 is connected to the main body opening 41. The vacuum cleaner 11 may have a plurality of suction port bodies 22, and any one of the plurality of suction port bodies 22 is selectively connected to the main body opening 41 or the extension pipe 23.

[0038] In the general usage mode of the vacuum cleaner 11, the vacuum cleaner main body 21 is located above the suction port body 22 and the extension pipe 23. In addition, the vacuum cleaner 11 can be used with the vacuum cleaner main body 21, the suction port body 22, and the extension pipe 23 horizontally arranged, or can be used with the vacuum cleaner main body 21 located below the suction port body 22.

[0039] The storage battery 24 is a rechargeable battery such as a lithium-ion battery, for example. The storage battery 24 is stored in the handle 43 of the vacuum cleaner housing 31, for example. In addition, the position of the storage battery 24 is not limited to this example. The storage battery 24 supplies power to the first electric blower 32.

[0040] The electric vacuum cleaner 11 can be detachably mounted on the station 12 in a state where the suction port body 22 and the extension pipe 23 are connected to the vacuum cleaner main body 21. The electric vacuum cleaner 11 is mounted on the station 12 so as to be located in front of the station 12.

[0041] The station 12 can collect the dust accumulated in the first dust collection part 33 and can charge the storage battery 24. In addition, the station 12 is not limited to this example. The station 12 has a bracket 51, a pedestal 52, a communication pipe 53, and a station main body 54.

[0042] The bracket 51 holds the electric vacuum cleaner 11 detachably. The bracket 51 holds, for example, the vacuum cleaner main body 21. In addition, the bracket 51 may also hold the suction port body 22 or the extension pipe 23.

[0043] The bracket 51 holds the electric vacuum cleaner 11, for example, in such a manner that the extension pipe 23 extends substantially vertically. When the bracket 51 holds the electric vacuum cleaner 11, the vacuum cleaner main body 21 is located above the suction port body 22.

[0044] The pedestal 52 protrudes, for example, from the station main body 54 in the forward direction (-Y direction). The pedestal 52 is located below the bracket 51. When the bracket 51 holds the electric vacuum cleaner 11, the pedestal 52 holds the suction port body 22. When held by the pedestal 52, the suction port body 22 extends along the substantially X direction. For example, the pedestal 52 restricts the electric vacuum cleaner 11 from tipping over by supporting the front end of the suction port body 22 with claws.

[0045] The communication pipe 53 extends substantially vertically. The extension pipe 23 and the communication pipe 53 are arranged in the Y direction and extend substantially parallel to each other. The upper end portion of the communication pipe 53 in the +Z direction is connected to the vacuum cleaner main body 21. The lower end portion of the communication pipe 53 in the -Z direction is connected to the station main body 54.

[0046] A passage 61 is provided in the communication pipe 53. The passage 61 extends along the communication pipe 53. When the electric vacuum cleaner 11 is held by the bracket 51, the passage 61 communicates with the dust collection chamber 45 of the first dust collection part 33 by opening the valve 47. That is, when the electric vacuum cleaner 11 is held by the bracket 51, the communication pipe 53 communicates with the first dust collection part 33.

[0047] The station main body 54 is formed, for example, in a substantially rectangular parallelepiped shape. The length (front-rear width) of the station main body 54 in the Y direction is shorter than the length (lateral width) in the X direction and shorter than the length (height) in the Z direction. In addition, the station main body 54 is not limited to this example.

[0048] Figure 3 is a cross-sectional view showing the station 12 of the present embodiment. As Figure 3As shown, the station main body 54 includes a station frame body 71, a second electric blower 72, a second dust collection unit 73, and a station control unit 74.

[0049] The station frame body 71 is formed, for example, in the shape of a substantially rectangular parallelepiped box. The station frame body 71 houses at least a part of the second electric blower 72, the second dust collection unit 73, and the station control unit 74.

[0050] The station frame body 71 has an upper surface 71a and a left surface 71b. The upper surface 71a is provided at the end of the station frame body 71 in the upward direction (+Z direction). The upper surface 71a is a substantially rectangular plane extending along the X direction and faces upward. The communication pipe 53 protrudes upward from the approximate center of the upper surface 71a. In addition, the bracket 51 and the communication pipe 53 may also be integrally formed with the station frame body 71. The left surface 71b is provided at the end of the station frame body 71 in the left direction.

[0051] The second electric blower 72 is provided with a suction port 81. The suction port 81 opens upward (+Z direction). The second electric blower 72 is driven by electricity. The second electric blower 72 generates a negative pressure and sucks air from the suction port 81.

[0052] Figure 4 It is a perspective view showing a cut-away view of the station 12 of the present embodiment. As Figure 4 shown, the second dust collection unit 73 is located above the second electric blower 72. The second dust collection unit 73 includes an inner wall 91, an inner pipe 92, a plurality of ribs 93, a holding body 94, and a lid 95. In addition, the second dust collection unit 73 is not limited to this example.

[0053] The inner wall 91 is formed, for example, in the shape of a substantially rectangular parallelepiped box that opens in the left direction (-X direction). The length (front-rear width) of the inner wall 91 in the Y direction is shorter than the length (lateral width) in the X direction and shorter than the length (height) in the Z direction. In addition, the inner wall 91 is not limited to this example. The inner wall 91 may also be integrally formed with the station frame body 71. The inner wall 91 has an upper wall 101, a bottom wall 102, two side walls 103, and an end wall 104.

[0054] The upper wall 101 and the bottom wall 102 are each formed in the shape of a substantially rectangular plate that is substantially horizontally disposed. That is, the upper wall 101 and the bottom wall 102 are each substantially orthogonal to the Z direction. The upper wall 101 is located above the bottom wall 102. The two side walls 103 are separated from each other and connect the edges of the upper wall 101 and the bottom wall 102 in the front direction (+Y direction) and the rear direction (-Y direction). The end wall 104 connects the edges of the upper wall 101 and the bottom wall 102 in the right direction (+X direction).

[0055] In the second dust collection unit 73, a storage chamber 111 is provided. The storage chamber 111 is provided inside the inner wall 91. In other words, the inner wall 91 defines the storage chamber 111. The storage chamber 111 is a space in a substantially rectangular parallelepiped shape. The bottom wall 102 separates the storage chamber 111 from the second electric blower 72.

[0056] The inner pipe 92 is connected to the end of the communication pipe 53 in the downward (-Z direction). The inner pipe 92 is integrally formed with the communication pipe 53, for example. Alternatively, the inner pipe 92 may be a component different from the communication pipe 53. The inner pipe 92 extends obliquely leftward and downward from the end of the communication pipe 53 in the upward direction through the upper wall 101. Note that the inner pipe 92 is not limited to this example.

[0057] In the second dust collection unit 73, an inner pipe line 112 and an air inlet 113 are also provided. The inner pipe line 112 is provided inside the inner pipe 92 and extends along the inner pipe 92. The end of the inner pipe line 112 in the upward (+Z direction) communicates with the passage 61 of the communication pipe 53.

[0058] The air inlet 113 is provided at the end 92a of the inner pipe 92 in the downward (-Z direction). Therefore, the air inlet 113 communicates with the dust collection chamber 45 through the inner pipe line 112, the passage 61, and the discharge port 46. In other words, the air inlet 113 communicates with the first dust collection unit 33 through the communication pipe 53. The air inlet 113 opens into the storage chamber 111 above the bottom wall 102. Note that the air inlet 113 is not limited to being provided in the inner pipe 92 and may be provided at other positions such as the upper wall 101.

[0059] The air inlet 113 faces obliquely leftward and downward. That is, the air inlet 113 faces a direction closer to the left direction (-X direction) than the downward direction (-Z direction). Note that the direction of the air inlet 113 is not limited to this example.

[0060] In the second dust collection unit 73, an exhaust port 114 is also provided. The exhaust port 114 penetrates the bottom wall 102 substantially vertically. That is, the exhaust port 114 opens into the storage chamber 111 at a position below the air inlet 113. The exhaust port 114 opens into the storage chamber 111 in the substantially upward direction (+Z direction). Note that the exhaust port 114 is not limited to this example and may be provided, for example, at the end of a pipe protruding from the bottom wall 102.

[0061] The suction port 81 of the second electric blower 72 faces the exhaust port 114 and communicates with the storage chamber 111 through the exhaust port 114. Therefore, the second electric blower 72 sucks the air in the storage chamber 111 through the exhaust port 114. Further, the second electric blower 72 sucks the air from the dust collection chamber 45 through the exhaust port 114, the storage chamber 111, the intake port 113, the inner pipe 112, the passage 61, and the discharge port 46. In other words, the second electric blower 72 sucks the dust-containing air from the first dust collection part 33 through the communication pipe 53.

[0062] A replacement port 115 and two guide grooves 116 are also provided in the second dust collection part 73. The replacement port 115 opens on the left surface 71b of the station frame body 71. The replacement port 115 communicates the end portion 111a of the storage chamber 111 in the left direction (-X direction) with the outside of the station 12. The two guide grooves 116 are respectively provided on the corresponding side walls 103 and open toward the replacement port 115.

[0063] A plurality of ribs 93 are provided at the end portion 111b of the storage chamber 111 in the right direction (+X direction). The ribs 93 project from the end wall 104 toward the left direction and extend substantially vertically. The plurality of ribs 93 are arranged at intervals in the Y direction and extend substantially parallel to each other.

[0064] The holding body 94 is formed in a plate shape extending along the Y direction. Both end portions of the holding body 94 in the Y direction are inserted into the two guide grooves 116. Thus, the holding body 94 is held by the two side walls 103. The holding body 94 can be inserted into the storage chamber 111 through the replacement port 115.

[0065] The cover 95 is attached to the station frame body 71. The cover 95 can detachably block the replacement port 115. By attaching the cover 95 to the station frame body 71, the exposure of the holding body 94 from the storage chamber 111 to the outside is restricted. By removing the cover 95 from the station frame body 71, the holding body 94 can be taken out of the storage chamber 111 through the replacement port 115.

[0066] The center of the intake port 113 is eccentric to the left from the center of the storage chamber 111. That is, the intake port 113 is closer to the end portion 111a of the storage chamber 111 in the left direction (-X direction) than the end portion 111b of the storage chamber 111 in the right direction (+X direction).

[0067] The center of the exhaust port 114 is eccentric to the right from the center of the storage chamber 111. That is, the exhaust port 114 is closer to the end portion 111b of the storage chamber 111 in the right direction than the end portion 111a of the storage chamber 111 in the left direction.

[0068] The air inlet 113 is located near the upper left corner of the storage chamber 111. On the other hand, the air outlet 114 is located near the lower right corner of the storage chamber 111. That is, the air inlet 113 and the air outlet 114 are in a diagonal position with respect to the storage chamber 111.

[0069] The electric vacuum cleaner device 10 further includes a dust collection bag 120. The dust collection bag 120 is detachably attached to the holding body 94 and is stored in the storage chamber 111 together with the holding body 94. The dust collection bag 120 includes a filter medium 121 and a support frame 122.

[0070] Figure 5 is a perspective view showing the dust collection bag 120 of the present embodiment. As Figure 5 shown, the filter medium 121 is made of fibers such as paper and is formed in a substantially rectangular parallelepiped bag shape. As Figure 5 shown by the double-dot chain line, the filter medium 121 is folded into a rectangular plate shape before use. Figure 3 shows the filter medium 121 opened (expanded) into a bag shape, Figure 4 shows the folded filter medium 121. In addition, the filter medium 121 is not limited to this example. As Figure 5 shown, an inlet 125 is provided in the filter medium 121. The inlet 125 communicates the inside and the outside of the bag-shaped filter medium 121.

[0071] The support frame 122 is made of, for example, cardboard or synthetic resin. Therefore, the support frame 122 is harder than the filter medium 121. The support frame 122 is formed in a substantially rectangular plate shape. The support frame 122 is attached to the filter medium 121 by bonding, for example, and surrounds the inlet 125. The support frame 122 strengthens the filter medium 121 around the inlet 125.

[0072] As Figure 3 shown, the holding body 94 holds the support frame 122 with the inlet 125 facing substantially upward (+Z direction). When the holding body 94 is inserted into the guide groove 116, the support frame 122 is pressed against the end portion 92a of the inner tube 92, and the inlet 125 of the dust collection bag 120 communicates with the air inlet 113. That is, the second dust collection unit 73 holds the dust collection bag 120 in such a manner that the dust collection bag 120 communicates with the air inlet 113.

[0073] The end portion 92a of the inner tube 92 is made of an elastic body such as synthetic rubber. Therefore, the end portion 92a of the inner tube 92 is in close contact with the support frame 122, and the gap between the inner tube 92 and the support frame 122 can be sealed.

[0074] The holding body 94 can be inserted into the storage chamber 111 through the replacement port 115 while holding the dust collection bag 120. In addition, the holding body 94 can be taken out from the storage chamber 111 through the replacement port 115 while holding the dust collection bag 120. That is, the dust collection bag 120 can pass through the replacement port 115.

[0075] The center of the support frame 122 and the center of the introduction port 125 are eccentric from the center of the filter medium 121. The support frame 122 and the introduction port 125 are closer to the end 121a of the filter medium 121 in the left direction (-X direction) than to the end 121b of the filter medium 121 in the right direction (+X direction).

[0076] The holding body 94 holds the support frame 122 in an inclined manner. Therefore, the filter medium 121 is also arranged in an inclined manner. The end 121a of the filter medium 121 in the left direction is located at a position higher than the end 121b of the filter medium 121 in the right direction. Therefore, the second dust collection part 73 holds the support frame 122 in an inclined manner so that the end 121b of the filter medium 121 in the right direction approaches the exhaust port 114.

[0077] The station control part 74 is located, for example, below the second dust collection part 73 and is arranged in the X direction with the second electric blower 72. In addition, the station control part 74 is not limited to this example. The station control part 74 controls the whole of the station 12.

[0078] The station control part 74 has, for example, a power supply circuit. The station control part 74 supplies power from an external power supply and supplies power to the second electric blower 72. Further, the station control part 74 charges the storage battery 24 of the electric vacuum cleaner 11 through the support 51.

[0079] In the above electric vacuum cleaner device 10, the electric vacuum cleaner 11 is detached from the station 12 during use. The electric vacuum cleaner 11 sucks air containing dust through the suction port body 22 by the first electric blower 32. The first dust collection part 33 accumulates the dust contained in this air.

[0080] The electric vacuum cleaner 11 is installed on the station 12 after use. That is, the support 51 holds the electric vacuum cleaner 11, and the pedestal 52 supports the suction port body 22. The station control part 74 detects, for example, the situation that the electric vacuum cleaner 11 is installed on the station 12 through energization, a mechanical switch, or an optical sensor.

[0081] When the electric vacuum cleaner 11 is installed on the station 12, the station control part 74 drives the second electric blower 72. The second electric blower 72 sucks air from the passage 61 through the exhaust port 114, the storage chamber 111, the intake port 113, and the inner pipe 112. Thereby, a negative pressure is generated in the passage 61, and the valve 47 of the first dust collection part 33 is opened by using this negative pressure. In addition, the valve 47 is not limited to this example, and can also be mechanically opened through the support 51, for example.

[0082] The second electric blower 72 sucks in the dust-containing air from the dust collection chamber 45 through the exhaust port 114, the storage chamber 111, the intake port 113, the inner pipe 112, the passage 61, and the discharge port 46. The dust-containing air flows from the dust collection chamber 45 into the introduction port 125 of the filter material 121 through the discharge port 46, the passage 61, the inner pipe 112, and the intake port 113. The filter material 121 is opened by this air. In addition, the filter material 121 is not limited to this example, and for example, it can also be opened by the negative pressure generated at the exhaust port 114.

[0083] The air flows into the exhaust port 114 through the filter material 121 and is sucked in by the suction port 81 of the second electric blower 72. On the other hand, the dust is trapped by the filter material 121 without passing through the filter material 121. That is, the filter material 121 of the dust collection bag 120 separates the dust from the air sucked in by the second electric blower 72. The second dust collection unit 73 accumulates the dust contained in the air sucked in by the second electric blower 72 in the dust collection bag 120. In other words, the second dust collection unit 73 recovers the dust accumulated in the first dust collection unit 33 into the dust collection bag 120.

[0084] As Figure 3 shown by the arrow A1 in [], the air flows obliquely downward from the intake port 113 into the introduction port 125. In other words, the intake port 113 causes the air to flow toward the end 111a of the storage chamber 111 in the left direction (-X direction). The air flowing into the interior of the filter material 121 from the intake port 113 does not directly face the exhaust port 114 but temporarily moves away from the exhaust port 114.

[0085] The air shown by the arrow A1 pushes the filter material 121 downward. Therefore, the filter material 121 that is folded thinly in the Z direction can be effectively opened. By opening the filter material 121 into a bag shape, the air can easily flow inside the filter material 121.

[0086] As Figure 3 shown by the arrow A2 in [], after the air moves away from the exhaust port 114, it bends toward the exhaust port 114 and flows inside the filter material 121. In addition, as Figure 3 shown by the arrow A3 in [], within a relatively wide range between the two ends of the filter material 121, the air flows out to the outside of the filter material 121. Thus, not only near the intake port 113, but also the entire filter material 121 can be effectively opened.

[0087] As Figure 3As shown by arrow A4, air flows out from near the end portion 121b of the filter material 121 toward the exhaust port 114. Therefore, dust mainly accumulates near the end portion 121b. However, the filter material 121 is effectively opened, and it is difficult for air to flow linearly toward the end portion 121b of the filter material 121. Therefore, a wider portion of the filter material 121 can trap dust. Thus, the vacuum cleaner device 10 can prevent the exhaust port 114 from being blocked by dust that only accumulates at the end portion 121b of the filter material 121.

[0088] When the filter material 121 is opened, the end portion 121b of the filter material 121 sometimes comes into contact with the rib 93. The end portion 121b of the filter material 121 can smoothly move vertically along the rib 93. That is, the rib 93 hardly hinders the opening of the filter material 121.

[0089] Even if the end portion 121b of the filter material 121 comes into contact with the rib 93, the gaps between the plurality of ribs 93 communicate the space above the filter material 121 with the space below. Therefore, the air flowing upward from the inside of the filter material 121 can flow toward the exhaust port 114 through the gaps between the plurality of ribs. Thus, the inner surface on the upper side of the filter material 121 can also effectively trap dust.

[0090] When the filter material 121 is filled with dust, the user replaces the dust collection bag 120. For example, the cover 95 is removed from the station frame body 71, thereby opening the replacement port 115. Then, the holding body 94 is taken out from the storage chamber 111 through the replacement port 115. Since the holding body 94 is located near the replacement port 115, the user can easily hold it.

[0091] Outside the storage chamber 111, the dust collection bag 120 is removed from the holding body 94. Then, a new dust collection bag 120 is installed on the holding body 94. Then, the holding body 94 and the dust collection bag 120 are inserted into the storage chamber 111 through the replacement port 115. The replacement port 115 is blocked by the cover 95, thereby completing the replacement of the dust collection bag 120.

[0092] The station 12 is arranged along the wall surface of the room in the X direction at the edge of the wall, thereby enabling effective utilization of the room. Since the replacement port 115 is opened on the left surface 71b of the station frame body 71, the user can easily open the cover 95 to replace the dust collection bag 120.

[0093] In the vacuum cleaner device 10 of the embodiment described above, the vacuum cleaner 11 includes a suction port body 22, a first electric blower 32, a first dust collection unit 33, and a storage battery 24. The first electric blower 32 sucks air containing dust through the suction port body 22. The first dust collection unit 33 accumulates the dust contained in the air sucked by the first electric blower 32. The storage battery 24 supplies power to the first electric blower 32. The station 12 includes a bracket 51, a communication pipe 53, a second electric blower 72, and a second dust collection unit 73. The bracket 51 holds the vacuum cleaner 11 so that it can be disassembled and assembled. When the vacuum cleaner 11 is held on the bracket 51, the communication pipe 53 communicates with the first dust collection unit 33. The second electric blower 72 sucks air containing dust from the first dust collection unit 33 through the communication pipe 53. The second dust collection unit 73 accumulates the dust contained in the air sucked by the second electric blower 72 in the dust collection bag 120. A storage chamber 111, an air inlet 113, and an air outlet 114 are provided in the second dust collection unit 73. The storage chamber 111 stores the dust collection bag 120. The air inlet 113 opens into the storage chamber 111 and communicates with the first dust collection unit 33 through the communication pipe 53. The air outlet 114 opens into the storage chamber 111 at a position below the air inlet 113. The second dust collection unit 73 holds the dust collection bag 120 so that the dust collection bag 120 communicates with the air inlet 113. The second electric blower 72 sucks the air in the storage chamber 111 through the air outlet 114. The air inlet 113 is closer to the end 111a of the storage chamber 111 in the -X direction, which is more horizontal, than the end 111b of the storage chamber 111 in the +X direction opposite to the -X direction. The air outlet 114 is closer to the end 111b of the storage chamber 111 in the +X direction than the end 111a of the storage chamber 111 in the -X direction.

[0094] The air inlet 113 and the air outlet 114 are located on opposite sides of each other in the vertical direction and the lateral width direction. Therefore, when the second electric blower 72 sucks air into the storage chamber 111 through the air inlet 113, it is difficult for this air to flow straight through the air inlet 113. For example, the air flowing into the inside of the dust collection bag 120 from the air inlet 113 bends toward the air outlet 114 and flows obliquely. Therefore, due to the flow of this air, the dust collection bag 120 is easily opened. In addition, the dust that enters the inside of the dust collection bag 120 together with the air is difficult to accumulate in a specific part. Thus, the vacuum cleaner device 10 can prevent the clogging of the dust collection bag 120 and can utilize the dust collection bag 120 as a whole.

[0095] A replacement port 115 is provided in the second dust collection unit 73. The replacement port 115 communicates the end portion 111a of the storage chamber 111 in the -X direction with the outside of the station 12. The dust collection bag 120 can pass through the replacement port 115. The second dust collection unit 73 has a lid 95 that can be detachably attached to block the replacement port 115. The intake port 113 is close to the end portion 111a of the storage chamber 111 in the -X direction. Therefore, the support frame 122 of the dust collection bag 120 is also close to the end portion 111a of the storage chamber 111 in the -X direction. Since the end portion 111a of the storage chamber 111 in the -X direction communicates with the outside through the replacement port 115, the dust collection bag 120 can be easily replaced through the replacement port 115.

[0096] The dust collection bag 120 has a bag-shaped filter medium 121 and a support frame 122 attached to the filter medium 121. The support frame 122 is closer to the end portion 121a of the filter medium 121 in the -X direction than the end portion 121b of the filter medium 121 in the +X direction. The second dust collection unit 73 holds the support frame 122 obliquely so that the end portion 121b of the filter medium 121 in the +X direction approaches the exhaust port 114. The air flowing into the inside of the filter medium 121 from the intake port 113 flows obliquely along the inclination of the filter medium 121 toward the exhaust port 114. Thus, due to the flow of this air, the dust collection bag 120 is easily opened. Therefore, the vacuum cleaner device 10 can prevent the dust collection bag 120 from being clogged and can utilize the dust collection bag 120 as a whole. In addition, since the support frame 122 is eccentric with respect to the filter medium 121, the dust collection bag 120 can be effectively arranged in the storage chamber 111.

[0097] The intake port 113 faces a direction closer to the -X direction than the downward direction (-Z direction). The air flowing into the inside of the filter medium 121 from the intake port 113 temporarily moves away from the exhaust port 114. Therefore, the air flows curvedly or in multiple directions inside the filter medium 121. Due to the flow of this air, the dust collection bag 120 is easily opened. Therefore, the vacuum cleaner device 10 can prevent the dust collection bag 120 from being clogged and can utilize the dust collection bag 120 as a whole. In addition, since the intake port 113 faces obliquely or horizontally, it is not necessary to arrange the communication pipe 53 to deviate in the -X direction. Therefore, it is possible to suppress the enlargement and deterioration of the appearance of the station 12.

[0098] The second dust collection part 73 has a plurality of ribs 93. The plurality of ribs 93 are provided at the end 111b of the storage chamber 111 in the +X direction and extend perpendicular to and parallel to the end 111b. The ribs 93 can reduce the friction in the up-and-down direction. Therefore, when the end 121b of the filter material 121 of the dust collection bag 120 in the +X direction contacts the ribs 93, it can smoothly move in the up-and-down direction. Thus, the ribs 93 can easily open the dust collection bag 120. Further, when the end 121b of the filter material 121 in the +X direction contacts the ribs 93, air can flow through the gaps between the plurality of ribs 93. Thus, it is possible to suppress the ribs 93 from obstructing the air flow in the storage chamber 111, and the dust collection bag 120 can be utilized as a whole.

[0099] The second electric blower 72 is provided with a suction port 81 that faces the exhaust port 114 and sucks air. The suction port 81 of the second electric blower 72 and the exhaust port 114 of the second dust collection part 73 are arranged in a straight line. Thus, the second electric blower 72 can effectively suck the air in the storage chamber 111 into the suction port. Further, the flow path between the second electric blower 72 and the exhaust port 114 becomes shorter, and the enlargement of the station 12 can be suppressed.
