[0002] Conventionally, there are vacuum cleaners that can prevent the dust container from clogging with dust by generating a swirling flow in the dust container and maintain suction power. For example, Patent Document 1 describes a vacuum cleaner that generates a swirling flow containing dust inside a cylindrical dust container and separates the air and dust by centrifugal force. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2009-061307 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, to realize a compact vacuum cleaner, the dust collection container must also be made small, but if the inner diameter of the dust collection container is small, it becomes difficult to create a swirling flow. For example, to create an appropriate swirling flow in a small dust collection container, the suction port on the peripheral wall of the dust collection container must be made narrow, but there is a risk that the suction port will become clogged when large dust is sucked in.

[0005] The present invention has been made in consideration of the above-mentioned problems, and has an object to provide a dust collection container that can be made compact, and a vacuum cleaner equipped with the dust collection container. [Means for solving the problem]

[0007] In addition, in order to achieve the above-mentioned object, a vacuum cleaner which is one aspect of the present invention comprises a dust collection container which includes a cylindrical first separating member which is closed at one end and open at the other, a suction pipe which is provided on the outer surface of the first separating member and which communicates with a suction hole provided in the peripheral wall of the first separating member, a protruding member which protrudes from the center of the closed portion of the first separating member toward an opening, a cylindrical filter member which extends outward from the open end of the first separating member in the direction of the pipe axis from the closed portion toward the opening, and a first storage portion which is disposed on the opposite side of the first separating member to the filter member and which stores dust which is centrifuged out of the air by a swirling air flow generated inside the first separating member, and a suction device which creates negative pressure inside the first separating member via the filter member.

[0010] Hereinafter, the embodiment of the dust collecting container and the vacuum cleaner according to the present invention will be described with reference to the drawings. Note that the following embodiment is an example for explaining the present invention, and is not intended to limit the present invention. For example, the shapes, structures, materials, components, relative positional relationships, connection states, numerical values, mathematical expressions, contents of each step in the method, and the order of each step shown in the following embodiment are examples, and may include contents not described below. In addition, geometric expressions such as parallel and orthogonal may be used, but these expressions do not indicate mathematical strictness, and include errors, deviations, etc. that are substantially allowed. In addition, expressions such as simultaneous and identical also include a substantially allowed range.

[0011] In addition, the drawings are schematic diagrams in which emphasis, omission, or adjustment of the ratio is appropriately performed in order to explain the present invention, and differ from the actual shapes, positional relationships, and ratios. In addition, the X-axis, Y-axis, and Z-axis that may be shown in the drawings indicate orthogonal coordinates that are arbitrarily set for the explanation of the drawings. In other words, the Z-axis is not necessarily an axis along the vertical direction, and the X-axis and Y-axis are not necessarily present in a horizontal plane.

[0012] In addition, in the following, a plurality of inventions may be collectively described as one embodiment, and some of the contents described below are described as optional components related to the present invention.

[0013] FIG. 1 is a perspective view showing a vacuum cleaner 200. The vacuum cleaner 200 is a device that sucks in air together with dust and separates and holds the dust from the sucked air, and includes a dust collection container 100 and a suction device 210. Here, the term "dust" is used to include dirt, dust, dirt, living things such as mites, etc. that are large enough for the vacuum cleaner 200 to suck up. In the present embodiment, the vacuum cleaner 200 is a so-called stick-type device, and includes a head 220, a pipe 230, and a grip 240. Note that, although a stick-type vacuum cleaner 200 is exemplified in the present embodiment, the vacuum cleaner 200 may be a canister type, a robot type capable of autonomous travel, or the like.

[0014] The suction device 210 is a device that includes a motor (not shown) and a fan (not shown) and generates suction force by rotating the fan with the motor. In the case of this embodiment, the suction device 210 generates suction force by creating a negative pressure inside the dust collection container 100, and sucks air containing dust into the dust collection container 100.

[0015] The head 220 is a member to which the suction force generated by the suction device 210 is transmitted via the pipe 230, and which comes into contact with a cleaning surface, such as a floor surface, to suck up dust together with air over a wide range. The head 220 is connected in communication with the pipe 230 and is connected to the pipe 230 so as to be rotatable relative to the pipe 230.

[0016] The pipe 230 is a hard cylindrical member that connects the head 220 and the gripping portion 240 in an interposed state. The pipe 230 forms a transport path that transports the air sucked in together with dust from the head 220 to the dust collection container 100.

[0017] The grip portion 240 is a portion that is gripped by the user. In the present embodiment, the grip portion 240 houses a battery for driving the suction device 210, a control device for controlling the suction device 210, and the like.

[0018] FIG. 2 is a perspective view showing the appearance of dust collection container 100. Arrows indicate the flow of air. FIG. 3 is a cross-sectional view of dust collection container 100. Dust collection container 100 is a member that separates dust from air sucked by suction device 210, holds the dust, and discharges the air, and includes first separation member 110, suction pipe 130, protruding member 140, filter member 150, and first storage section 161. In the case of this embodiment, dust collection container 100 includes second separation member 120, second storage section 162, cover member 170, and outer cylinder 180.

[0019] The first separating member 110 is a cylindrical member with one end closed and the other end open, and separates the dust from the air by centrifugal force by swirling the dust-containing air. The shape of the first separating member 110 is not limited, but in the present embodiment, the first separating member 110 is cylindrical, with one end (the end on the Z+ side (upper side) in the figure) covered by a blocking portion 112, and the other end (the end on the Z- side (lower side) in the figure) forming an opening 113. The peripheral wall of the first separating member 110 is provided with a suction hole 111 through which the dust-containing air flows in. The cross-sectional shape of the first separating member 110 perpendicular to the tube axis may be a D-shape or the like. When the first separating member 110 has a corner on its inner surface, such as the first separating member 110 with a D-shaped cross section, it is preferable that the corner be rounded with a smooth curved surface.

[0020] In the present embodiment, the length L1 (see FIG. 3) of the first separating member 110 in the tube axis direction (Z-axis direction in the drawing) is longer than the length L2 of the filter member 150 (described in detail later). This allows the air containing dust to swirl sufficiently within the first separating member 110, and the dust can be effectively separated from the air.

[0021] The suction pipe 130 is a tubular member provided on the outer peripheral surface of the first separating member 110 and communicating with a suction hole 111 provided in a penetrating manner in the peripheral wall of the first separating member 110. In the case of the present embodiment, the suction pipe 130 is connected in a communicating state to a pipe 230 of the vacuum cleaner 200. Air containing dust sucked by the suction device 210 flows into the suction pipe 130 via the head 220 and the pipe 230.

[0022] FIG. 4 is a side view of the dust collection container 100 from the outside to the inside in the axial direction of the suction pipe 130 (X-axis direction in the drawing). In FIG. 4, the first separation member 110 is hatched to clearly show the suction hole 111. In FIG. 4, the hatching does not indicate a cross section. FIG. 5 is a cross-sectional view showing the first separation member 110 cut along line II in FIG. 4. The opening area of ​​the suction hole 111 is smaller than the opening area of ​​the suction pipe 130 facing the suction hole 111. The suction hole 111 is biased toward the downstream side of the swirling air flow with respect to the suction pipe 130. In other words, when viewed in the axial direction of the suction pipe 130, the suction hole 111 is biased in a direction away from the pipe axis 101 of the first separation member 110. In the case of this embodiment, the suction hole 111 is rectangular and is provided so that the tangent surface of the inner peripheral surface of the first separation member 110 and one side of the suction hole 111 coincide or almost coincide. The inner shape of the suction pipe 130 is also rectangular, and the suction pipe 130 is arranged so that the contact surface of the inner circumferential surface of the first separation member 110 and one surface of the inner surface of the suction pipe 130 coincide or nearly coincide.

[0023] When the inside of the suction pipe 130 is viewed from the pipe axis direction of the suction pipe 130, the peripheral wall of the first separation member 110 protrudes in a direction away from the pipe axis 101, and a part of the opening of the suction pipe 130 is covered by the peripheral wall of the first separation member 110. As a result, the dust-containing air flowing from the suction pipe 130 into the inside of the first separation member 110 flows in as if it is pressed against the inner peripheral surface of the first separation member 110, making it easy for a swirling flow to occur within the first separation member 110.

[0024] The suction hole 111 is disposed with a predetermined gap from the blocking portion 112. In other words, the edge of the suction hole 111 and the blocking portion 112 are not in contact with each other. This makes it easier for an appropriate swirling flow of dust-containing air to occur inside the first separation member 110. The suction hole 111 is large enough to allow, for example, spherical dust with a diameter of about 1 cm or rectangular dust with one side of about 1 cm to pass through. This makes it possible to prevent the suction hole 111 from clogging even when relatively large dust is sucked in.

[0025] The protruding member 140 is a member that protrudes from the center of the blocking portion 112 of the first separation member 110 toward the opening 113. The shape of the protruding member 140 is not limited, but is preferably a columnar shape or a shape that tapers from the blocking portion 112 toward the opening 113. If the protruding member 140 is shaped to expand from the blocking portion 112 toward the opening, there is a high possibility that hair, lint, and the like sucked in as dust will become entangled and not fall off. In the case of this embodiment, the protruding member 140 has a shape that is an upside-down truncated cone. In addition, the protruding member 140 may be a cylindrical shape, a conical shape, a dome shape, a semicircular shape, or the like. In addition, the cross-sectional shape of the protruding member 140 perpendicular to the tube axis (the axis from the blocking portion 112 toward the opening 113) is not limited to a circle, and may be a D-shape, a polygon, or the like. It may be a shape similar to the cross-sectional shape of the inner circumferential surface of the first separation member 110. When corners are present on the periphery of the protruding member 140, such as the protruding member 140 having a D-shaped cross section, it is preferable that the corners be rounded with a smooth curved surface.

[0026] In the direction of the tube axis of the first separation member 110 (Z-axis direction in the figure), the tip of the protruding member 140 is disposed closer to the blocking portion 112 than the suction hole 111. In other words, in the direction of the tube axis of the first separation member 110 (Z-axis direction in the figure), the part of the protruding member 140 farthest from the blocking portion 112 is closer to the blocking portion 112 than the part of the edge of the suction hole 111 farthest from the blocking portion 112. In the case of this embodiment, in the direction of the tube axis of the first separation member 110 (Z-axis direction in the figure), the position of the tip face which is the part of the protruding member 140 farthest from the blocking portion 112 is disposed at or near the center position from the part closest to the blocking portion 112 on the edge of the suction hole 111 to the part farthest from the blocking portion 112.

[0027] The filter member 150 is a cylindrical member that allows air to pass through extending outward from the open end of the first separating member 110 in the direction of the tube axis from the closing portion 112 toward the opening 113 of the first separating member 110, and is provided with holes for separating air from dust. The filter member 150 separates dust that has not been completely separated by the first separating member 110 by filtering.

[0028] The shape of filter member 150 is not limited. In the present embodiment, filter member 150 has a shape in which the opening widens from first separation member 110 toward first storage section 161. Specifically, filter member 150 has a peripheral shape equivalent to that of a truncated cone. This makes it easier for dust separated by filter member 150 to fall into first storage section 161 without remaining on the inner surface of filter member 150.

[0029] The first storage section 161 is disposed on the opposite side of the first separating member 110 with respect to the filter member 150, and is a container-shaped portion that stores dust that is centrifuged from the air by the swirling air flow generated inside the first separating member 110, and stores dust that is separated by the filter member 150 and falls. In the case of this embodiment, the first storage section 161 is cylindrical, and both ends on the filter member 150 side and the side opposite the filter member 150 are open. In addition, the end opposite the filter member 150 is sealed by a cover member 170 so as to be openable and closable. By opening the cover member 170, the dust stored in the first storage section 161 can be discharged to the outside of the dust collection container 100.

[0030] The second separating member 120 separates dust from the dust-containing air that has passed through the filter member 150. The type of the second separating member 120 is not limited. For example, it may be a filter or the like. In the case of the present embodiment, the second separating member 120 generates a swirling air flow and separates dust by centrifugal separation.

[0031] Second storage section 162 is a container-shaped portion that stores dust separated by second separating member 120. In the case of the present embodiment, second storage section 162 is sealed by cover member 170 that seals first storage section 161 so as to be openable and closable.

[0032] In this embodiment, the outer cylinder 180 provided in the dust collection container 100 is a cylindrical member that surrounds the first separating member 110 with a predetermined gap between it and the outer peripheral surface of the first separating member 110, and forms a transport path that transports the dust-containing air that has passed through the filter member 150 to the second separating member 120. In addition, the outer cylinder 180 is formed integrally with the first storage section 161.

[0033] Next, the operation of the vacuum cleaner 200 equipped with the dust container 100 will be described. First, when the operation of the vacuum cleaner 200 equipped with the dust container 100 is started, a suction airflow is generated by the suction device 210 built into the vacuum cleaner 200, and air containing dust is sucked from the head 220. The sucked air containing dust is sucked into the dust container 100 via the pipe 230 and the suction tube 130.

[0034] As shown in FIG. 5, the air containing dust that has passed through the suction pipe 130 is narrowed by the suction hole 111 and flows in along the tangent of the inner surface of the first separating member 110 so as to be pressed against the inner surface of the first separating member 110. By arranging the suction pipe 130 and the suction hole 111 in this manner, the air containing dust is changed into a swirling flow in the first separating member 110. The generated swirling flow does not immediately reach the filter member 150 due to the presence of the protruding member 140, but gradually reaches the filter member 150 while swirling multiple times inside the first separating member 110. The dust is separated from the air by the swirling in the first separating member 110 and falls into the first storing section 161. Furthermore, even if long and thin dust such as hair and lint gets entangled in the protruding member 140, it easily falls into the first storing section 161 due to the shape of the protruding member 140, and hardly remains in the protruding member 140.

[0035] Furthermore, the swirling flow reaches the filter member 150 and flows downward while sliding on the surface of the filter member 150. When the air containing dust flows over the surface of the filter member 150, the dust remains inside the filter member 150 and the air passes through the filter member 150. The air containing fine dust that has passed through the filter member 150 passes between the first separating member 110 and the outer cylinder 180 and reaches the second separating member 120. In this way, the first separating member 110 and the filter member 150 separate the air containing coarse dust from the air containing fine dust.

[0036] Next, separation of the fine dust and the air is carried out by the second separation member 120. In the case of this embodiment, the second separation member 120 has a plurality of conical cyclone members 121 arranged on the circumference, and a swirling flow of air containing the fine dust is generated again in each cyclone member 121, separating the fine dust from the air. The fine dust separated from the air in the cyclone member 121 falls into the second storage section 162. The air passes through an exhaust hole 122 provided in the upper part of the cyclone member 121 and is returned to the atmosphere.

[0037] The present invention is not limited to the above-described embodiment. For example, the components described in this specification may be combined in any manner, or some of the components may be removed to create another embodiment of the present invention. In addition, the present invention also includes modifications that are made to the above-described embodiment by those skilled in the art without departing from the spirit of the present invention, i.e., the meaning of the words in the claims.

[0038] For example, the outer peripheral shape of the protruding member 140 is not limited to any particular shape, and may be a D-shape with a part of a circle cut out as shown in FIG.

[0039] 8, a guide member 190 may be provided that protrudes inward from the inner peripheral surface of the first separation member 110 and extends in a spiral shape around the tube axis. The guide member 190 guides the air, including dust, sucked into the first separation member 110 from the suction holes 111 so that the air becomes a swirling flow toward the filter member 150. In the case of this embodiment, one end of the guide member 190 is disposed between the suction holes 111 in the tube axis direction and on the periphery of the suction holes 111, and the other end is disposed on the filter member 150 side. In other words, the guide member 190 winds counterclockwise from the blocking portion 112 toward the opening end 113 when viewed from above (Z+ side in the figure).

[0040] The cross-sectional shape of the guide member 190 cut along a plane including the tube axis is not limited. In the present embodiment, the cross-sectional shape of the guide member 190 is a rectangle that is thinner in the vertical direction than in the horizontal direction. The number of turns of the spiral guide member 190 is not limited. In the present embodiment, the guide member 190 is wound three times from the upper end to the lower end of the first separation member 110. The portion of the guide member 190 corresponding to the suction hole 111 is cut out. In other words, the guide member 190 does not cross the suction hole 111, and the portion corresponding to the suction hole 111 is discontinued. The guide member 190 may be formed by forming a spiral groove in the thick first separation member 110. In other words, forming the guide member 190 by erecting a rib from the inner peripheral surface of the first separation member 110 is the same as forming the guide member 190 by providing a spiral groove on the inner peripheral surface of the first separation member 110.

[0041] The dust collection container 100 of the first aspect described in the above embodiment comprises a cylindrical first separation member 110 that is closed at one end and open at the other, a suction pipe 130 provided on the outer peripheral surface of the first separation member 110 and communicating with a suction hole 111 provided in the peripheral wall of the first separation member 110, a protruding member 140 that protrudes from the center of the blocking portion 112 of the first separation member 110 toward the opening 113, a cylindrical filter member 150 that extends outward from the open end of the first separation member 110 in the direction of the pipe axis from the blocking portion 112 toward the opening 113, and a first storage portion 161 that is arranged on the opposite side of the first separation member 110 from the filter member 150 and stores dust that is centrifuged from the air by a swirling air flow generated inside the first separation member 110.

[0042] According to the dust collection container 100 of the first aspect, since the protruding member 140 is provided inside the first separating member 110, even if the first separating member 110 is small enough to be provided in a stick-type vacuum cleaner 200, the dust-containing air sucked through the suction hole 111 can be made into a swirling flow, and the dust and the air can be effectively separated. The presence of the protruding member 140 allows the size of the suction hole 111 that sucks in the dust-containing air to be relatively large, and clogging of the suction hole 111 with dust can be prevented as much as possible.

[0043] The dust collecting container 100 of the second embodiment includes the dust collecting container 100 of the first embodiment, and the opening area of ​​the suction hole 111 is smaller than the opening area of ​​the suction pipe 130 facing the suction hole 111, and the suction hole 111 is biased toward the downstream side of the swirling air flow relative to the suction pipe 130.

[0044] According to the dust collection container 100 of the second embodiment, the airflow containing dust passing through the suction hole 111 flows in as if it is being pressed against the inner circumferential surface of the first separation member 110. Therefore, even with a small first separation member 110, a more effective swirling flow can be generated. Furthermore, due to the presence of the protruding member 140, an effective swirling flow can be generated even if the opening area of ​​the suction hole 111 is set to 70% or more of the opening area of ​​the suction tube 130. This makes it possible to prevent the suction hole 111 from becoming clogged with dust even when large dust particles are sucked in.

[0045] Dust collection container 100 of the third embodiment includes either the first embodiment or the second embodiment, and the tip of protruding member 140 is disposed closer to blocking portion 112 than suction hole 111 in the tube axis direction.

[0046] According to the third embodiment of the dust collection container 100, the protruding member 140 does not overlap with any part of the suction hole 111 in the axial direction of the tube, so that the pressure loss of the air flowing in from the suction hole 111 due to the protruding member 140 can be suppressed, and a decrease in the suction power of the vacuum cleaner 200 can be suppressed.

[0047] Dust collection container 100 of the fourth embodiment includes any of the first to third embodiments, and suction hole 111 is disposed with a predetermined gap from blocking portion 112 .

[0048] According to the dust collecting container 100 of the fourth aspect, the downward force that the swirling flow receives from the blocking portion 112 can be suppressed, and the swirling flow can be effectively retained within the first separating member 110.

[0049] The dust collection container 100 of the fifth aspect includes any one of the first to fourth aspects, and the filter member 150 widens toward the first storage portion 161.

[0050] According to the dust collection container 100 of the fifth aspect, the dust adhering to the inner surface of the filter member 150 can be easily dropped into the first storage portion 161.

[0051] The dust collection container 100 of the sixth embodiment includes any of the first to fifth embodiments, and the length L1 of the first separating member 110 is longer than the length L2 of the filter member 150 in the tube axis direction.

[0052] According to the dust collection container 100 of the sixth aspect, even though it is small, it is possible to effectively separate relatively large dust particles from the air, and clogging of the filter member 150 can be suppressed.

[0053] The dust collecting container 100 of the seventh embodiment includes any of the first to sixth embodiments, and is provided with a guide member 190 that protrudes inward from the inner circumferential surface of the first separating member 110 and extends spirally around the tube axis.

[0054] The dust collection container 100 of the eighth embodiment includes the dust collection container 100 of the seventh embodiment, and one end of the guide member is positioned between the suction holes 111 in the direction of the tube axis and on the peripheral edge of the suction holes 111, and the other end is positioned on the filter member 150 side.

[0055] According to the dust collecting container 100 of the seventh and eighth aspects, the swirling flow within the first separating member 110 can be stabilized, and even a small dust collecting container 100 can more effectively separate dust from the air.

[0056] The vacuum cleaner 200 of the ninth aspect described in the above embodiment includes any one of the dust collection containers 100 from the first aspect to the eighth aspect, and is equipped with a suction device 210 that creates negative pressure inside the first separating member 110 of the dust collection container 100 via the filter member 150.

[0057] According to the cleaner 200 of the ninth aspect, it is possible to achieve the effects corresponding to the above aspects.

[0058] The vacuum cleaner 200 of the tenth embodiment includes the vacuum cleaner of the ninth embodiment, and further includes a second separating member interposed between the filter member 150 and the suction device 210 in the suction path.

[0059] This makes it possible to separate fine dust that cannot be separated by the first separating member 110. [Industrial Applicability]
