Description

  The present invention relates to a vacuum cleaner.

  This will be described below with reference to FIG.

  The conventional vacuum cleaner collects sucked dust by providing a bag member such as a paper bag in the dust collection chamber 202. The dust sticks to the inside of the bag member 204, and the bag member 204 gradually begins to clog, and the suction force gradually decreases. Furthermore, since the pressure inside the dust collection chamber 202 is larger than the pressure inside the bag member 204 as a negative pressure, the bag member 204 sticks to the inner wall of the dust collection chamber 202 and the lid 101 and the wind The flowing space was reduced and the suction force was reduced.

  Therefore, by vibrating the bag member 204, a structure (for example, refer to Patent Document 1 and Patent Document 2) that removes dust adhered to the inner surface of the bag member 204 is created to prevent the bag member 204 from being clogged. As for securing the space through which the air flows, a convex rib 701 is provided inside the dust collection chamber 202 and the lid 101 to secure a space through which the wind flows.

JP 2004-174048 A Japanese Patent Laid-Open No. 5-123

  In the background art described above, the structure for removing dust is obtained by converting the movement when the power cord is pulled out to the movement of removing the bag member through the gear, or an electrical component (motor or solenoid). Since dust removal is used, the structure becomes complicated and the vacuum cleaner becomes large and heavy (for example, refer to Patent Document 1 and Patent Document 2).

  Further, in the conventional technology, dust is removed from the back of the bag member (on the side of the electric blower), so that dust may be attached to the dust removing unit again before falling down below the bag member.

  An object of the present invention is to provide a vacuum cleaner that solves the above-described problems and is small and light, and that can prevent a reduction in suction force by removing dust that is clogged in a bag member. .

  In order to achieve the above object, the present invention is characterized in that a vacuum cleaner having a dust collection chamber, a dust collection bag, an electric blower, and a lid for opening and closing the dust collection chamber inside the main body, A movable flow path component that provides a flow path space through which suction air flows is provided inside the lid.

  And the force which pushes the said flow-path structural member to the said dust bag direction with a spring is added.

  Alternatively, suction force flowing through the upper part of the flow path component member is used to apply a force for pushing the flow path component member in the dust bag direction.

  Alternatively, the flow path component member is disposed obliquely, and further, elastic deformation is used so that the flow path component member returns to the original obliquely disposed position even when the flow path component member moves.

  According to the present invention, a movable flow path component member that provides a flow path space through which suction air flows is provided inside the lid, and the power is turned on by applying a force to move the flow channel component member toward the dust bag. When the dust collecting bag lifts the flow path component member upward and the power is turned off, the flow channel component member is pushed downward and operates to crush the dust collection bag. As a result, it is possible to remove the dust stuck to the wall surface of the dust collection bag and causing clogging. At this time, since the upper portion of the bag member is removed, the dust that has been removed can be reliably dropped downward. Furthermore, the flow path component member provides a flow path between the lid body and a space through which wind flows. With these effects, it is possible to prevent a reduction in suction force, and it is possible to remove dust and secure a space for air flow with a single flow path component. It is also effective for weight reduction. Further, since the flow path component member operates, the amount of dust collection is not reduced even when the dust bag is full.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 2 is an overall external view of a vacuum cleaner according to an example of the embodiment of the present invention.

  Dust sucked from the suction port 301 passes through the extension pipe 302 and the hose 303 and is collected in the cleaner body 201.

  FIG. 3 is a cross-sectional view of the main body of the electric vacuum cleaner according to an example of the embodiment of the present invention. A dust collection chamber 202 and an electric blower 203 are provided inside the cleaner body 201, and a bag member 204 that collects the sucked dust is attached to the dust collection chamber 202. A support member 205 made of a hard material is integrally provided on the bag member 204, and is attached to the dust collection chamber 202 by this support member 205. A lid 101 that can be opened and closed is provided on the upper part of the dust collection chamber 202 so that the bag member 204 can be taken out. Further, the inside of the lid 101 is provided with a filter 102 for passing through the bag member 204 and keeping the suction air flowing along the lid 101 clean, and the channel member 103 as a pressing member is attached to the lid 101. It is attached.

  FIG. 4 is a view (a view of the cover viewed from the inside) of the vacuum cleaner according to an example of the embodiment of the present invention. The filter 102 is housed in a filter housing portion 104 inside the flow path constituting member 103, and wind flows between the inside of the lid 101 and the bag member 204 even if a bag member 204 (not shown) swells on the outer periphery thereof. A channel space 105 is provided so that the channel is not lost.

  The inlet 106 of the flow path space is opened on the side surface of the filter housing portion 102 to ensure the flow of air to the electric blower 204 (not shown). As indicated by the arrows in the drawing, the suction air enters from the lattice holes of the flow path component 103 and is guided to the electric blower from the exhaust port 108 (not shown) of the filter storage unit. As a result, air is actively blown to the filter 102 provided on the lid 101, and the suction air that has passed through the dust and exits from the bag member 204 can be cleaned. At the same time, the suction air is always guided from the inlet 106 of the flow path space to the flow path space 105, and the bag member 204 is inflated and can be prevented from lowering the suction force due to the reduction of the suction flow path due to sticking inside the lid 101. .

  FIG. 5 is a view of a filter holding part of a vacuum cleaner according to an example of the embodiment of the present invention. The inlet 106 of the channel space is located on the outer periphery of the filter storage unit 104, and in this embodiment, the channel is branched into two. The exhaust port 107 in the channel space is located behind the filter 102 (not shown), and has a small cross-sectional area with respect to the inlet 106 in the channel space, but a plurality of exhaust ports 107 are provided to the electric blower 204 (not shown). The flow of wind is secured. As a result, it is possible to keep the suction air clean because it can prevent the reduction of the suction force and actively flow the filter without reducing the volume of dust that can be collected in the dust collection chamber. I can do it.

  FIG. 1 is a partially enlarged view around a flow path component of a cross section of a main body of an electric vacuum cleaner according to an example of an embodiment of the present invention. FIG. 1a is a diagram illustrating that a flow path component is pushed upward by an inflated dust collection bag. FIG. 1B is an example of a diagram in which the flow path component member crushes the dust collection bag.

  When the vacuum cleaner 201 is turned on, the suction air flows into the bag member 204, so that the pressure increases and the bag member 204 expands. Since the support member 205 of the bag member 204 is located closer to the electric blower side (not shown) than the inlet 106 of the flow path space, the inflated bag member 204 prevents the inlet 106 of the flow path space from being blocked. ing. Further, the length from the inlet 106 of the channel space to the exhaust port 107 of the channel space, that is, the length of the channel space 105 is longer than the filter storage unit 104 in the direction of the air flow (the arrow direction in the figure). Since it is provided, the inflated bag member 204 prevents the passage space from being blocked.

  In addition, the flow path component 103 is configured to move up and down with the fulcrum at a point where the claw portion 109 of the lid body 101 and the fixing portion 403 of the flow path structure member 103 are in contact.

  FIG. 6A is a view in which a spring 401 is incorporated between the flow path constituting member 103 and the lid 101 of the electric vacuum cleaner according to an example of the embodiment of the present invention. 6B is an enlarged view of a portion A in FIG. 6A in a state where the flow path component 103 is pushed up by the bag member 204, and FIG. 6C is a view in FIG. 6A in a state where the flow path component 103 is pushed down by the spring 401. It is an A section enlarged view.

  When the vacuum cleaner 201 is turned on, the suction air flows into the bag member 204, so that the pressure increases and swells to push up the flow path component 103. Next, when the power of the vacuum cleaner is turned off, the flow path component 103 that has been pushed up is pushed down by the spring 401 and presses the bag member 204. As a result, dust attached to the inside of the bag member 204 can be dropped, the suction air drop can be reduced, and the suction efficiency can be improved.

  FIG. 7A shows a configuration in which a blade portion 402 is provided in the exhaust port 107 of the flow path space of the vacuum cleaner according to an example of the embodiment of the present invention.

  7b and 7c are partial enlarged views of the periphery of the blade portion 402 of the flow path component 101, FIG. 7b shows a state in which the bag member pushes up the flow path component 103, and FIG. The bag member 204 is being pressed.

  When the electric vacuum cleaner is turned on, the bag member 204 expands and pushes up the flow path component. This force is F1. Next, the suction air flowing through the flow path hits the blade portion 402 of the flow path constituting member, and a force F2 for pushing the flow path constituting member 103 downward is generated. When the flow path component 103 is pushed up by the bag member 204, the angle of the blade portion 402 is steep with respect to the suction air, so the force relationship is F1 <F2, and the flow path component 103 is The bag member 204 is crushed by being pushed down. Next, when the flow path component 103 is pushed down, the angle of the blade portion 402 becomes shallower with respect to the suction air, so that the force relationship becomes F1> F2, and the flow path component 103 is pushed up. By repeating the above, the flow path constituent member 103 vibrates, dust attached to the inside of the dust bag can be dropped, suction air drop can be reduced, and suction efficiency can be improved.

  FIG. 8a shows a fixing portion 403 in front of the flow path constituting member 103 of the electric vacuum cleaner according to an example of the embodiment of the present invention. Furthermore, the flow path component 103 is disposed in an initial state so as to be inclined in a direction in which the bag member 204 in the motor direction is pressed.

  8b and 8c are partially enlarged views of FIG. 8a. FIG. 8b shows a state where the flow path component is pushed up by the bag member, and FIG. 8d shows a state where the flow path component presses the bag member.

  When the power of the vacuum cleaner is turned on, the bag member 204 expands and pushes up the flow path component 103. However, since the flow path component is fixed by the fixing portion 403, the portion undergoes elastic deformation, and elastic energy is accumulated. Next, when the power of the vacuum cleaner is turned off, the flow path component 103 returns to the original position while crushing the bag member using the accumulated elastic energy. Thereby, the dust attached to the inside of the dust bag can be dropped, the suction air drop can be reduced, and the suction efficiency can be improved.

  As explained above, dust clogged on the upper part of the bag member is removed, so that it can be prevented that the dust is attached again to the dust removing part, and suction air can be sent more actively to the upper filter. It becomes.

  Moreover, since the flow path component has a dust removing function at the same time, it is advantageous in terms of size reduction and weight reduction.
