  Certainly, in the case of the electric vacuum cleaner described in Patent Document 1, the user can easily take out the dust collection bag together with the basket from the dust collection chamber by holding the handle and pulling it. However, the dust collection bag in the basket is greatly expanded by the action of the collected dust or suction air during use. Therefore, the expanded dust bag is in a state of being firmly fitted to the basket, and the dust bag cannot be easily detached even if the opening of the basket is directed downward. Therefore, the user may have to pick the dust bag directly and remove it from the basket. However, it is desirable to avoid direct contact with the dust bag from the viewpoint of hygiene.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a basket for an electric dust collector that can easily remove a dust bag, and an electric dust collector that includes the basket.

  A basket according to the present invention is a basket for a dust collection bag that is detachably attached to a dust collection chamber of an electric dust collection cleaner, and includes a basket body in which the dust collection bag is set, And a support wall that supports the dust bag and an opening that opens upward when mounted in the dust collection chamber, so that the opening expands when removed from the dust collection chamber. It is configured.

  By setting it as such a structure, the opening part of a basket main body spreads the direction of the state removed from the dust collection chamber rather than the state with which the dust collection chamber was mounted | worn. Therefore, a gap is formed between the basket body and the dust collection bag, and the frictional resistance between the two is reduced, so that the dust collection bag can be easily detached from the basket body.

  The support wall may have a deformed portion that deforms to widen the opening.

  Thus, if the deformation | transformation part is defined, the whole shape of the basket main body after a deformation | transformation can also be estimated to a substantially constant shape. Therefore, the design which expands an opening part to a desired condition becomes easy, and the basket which can remove a dust bag easily can be implement | achieved more reliably. It is also possible to integrally form the basket body by casting or the like so as to become one part, and in this case, it is possible to suppress the occurrence of defects in the basket due to fine dust. In addition, as the deforming portion, various specific configurations that are more easily deformable than other parts, such as a U-shaped or V-shaped shape, a thinned shape, or a material that is easily deformable, may be adopted. it can.

  Moreover, the said support wall consists of 2 to 3 structural members, and the said deformation | transformation part may be provided in the connection location of each structural member.

  Also in this case, the overall shape of the basket body after deformation can be estimated to be a substantially constant shape. Therefore, the design which expands an opening part to a desired condition becomes easy, and the basket which can remove a dust bag easily can be implement | achieved more reliably. In addition, as a deformation | transformation part provided in the connection location of a structural member, it is possible to employ | adopt various specific structures which deform | transform themselves, such as what was comprised with the easily deformable material different from a hinge and another site | part. it can. Moreover, a magnet and a ferromagnetic material may be attached to each constituent member connected by the deforming portion, and the constituent members may be fixedly connected so that the shape before the deformation can be maintained constant.

  Further, a handle pivotally supported on both sides of the basket main body and spanning above the opening may be provided.

  With this configuration, the user can easily take out the basket body from the electric dust collector with the handle. In addition, it is possible to easily remove the dust bag from the basket body, such as holding the handle with one hand and rotating the basket body with the other hand to direct the opening downward.

  The handle has an abutting portion that comes into contact with the basket body when the basket body is rotated so that the opening portion faces downward, and the basket body has the opening portion downward. When it is rotated with respect to the handle so as to face, it has a contacted portion that comes into contact with the contact portion of the handle, and as the handle and the basket body rotate relatively, You may comprise so that the opening part of the said basket main body may spread when the said contact part and the said to-be-contacted part mutually contact.

  With such a configuration, there is no need to separately perform an operation of rotating the basket body so that the opening portion faces downward and an operation of expanding the opening portion of the basket body. That is, if the operation of rotating the basket body is performed, the opening can be widened accordingly. Therefore, the dust bag can be detached from the basket body by an easier operation.

  Further, the support wall has a pair of side support walls that support the dust collection bag from both sides to form the opening at the top, and a bottom support wall that supports the dust collection bag from below, The handle is pivotally supported with respect to the pair of side support walls, and the bottom support wall is deformed when the basket body rotates and the contact part and the contacted part contact each other. The opening may be configured to expand.

  The contact portion of the handle is provided on both sides with a predetermined interval, the contact portion of the basket body is provided on both sides corresponding to the contact portion, and the basket body The interval on the downstream side is wider than the interval on the upstream side in the rotational direction, and the bottom support wall is configured such that the downstream portion is deformable to be larger than the upstream portion in the rotational direction. It may be.

  The basket body is rotatable in one direction around the pivot point of the handle from the state in which the opening is directed upward, and the center of gravity of the basket body is In order to generate a moment in the other direction around the pivot point of the handle, the basket body is provided at a position offset from the pivot position, and the basket body is rotated in the other direction around the pivot point. A locking portion that contacts and locks may be provided.

  With such a configuration, it is possible to prevent the basket body from rotating independently of the user's intention while the user holds the handle. Further, rattling of the basket body with respect to the handle can be suppressed, and the user can carry the handle and the basket body together.

  In addition, the basket body is rotatable in one direction around the pivot point of the handle from a state in which the opening portion is directed upward, and within the relative rotation range of the basket body and the handle, An interference unit that temporarily interferes with the basket body and the handle may be provided when the basket body is in a state where the opening is directed upward.

  In this case as well, it is possible to prevent the basket body from rotating independently of the user's intention while the user holds the handle. Further, rattling of the basket body with respect to the handle can be suppressed, and the user can carry the handle and the basket body together.

  In addition, the basket body is rotatable in one direction around the pivot point of the handle from a state in which the opening portion is directed upward, and within the relative rotation range of the basket body and the handle, A friction portion that restricts relative rotation of the basket body and the handle may be provided at least in a rotation section including a state in which the basket body faces the opening upward.

  In this case as well, it is possible to prevent the basket body from rotating independently of the user's intention while the user holds the handle. Further, rattling of the basket body with respect to the handle can be suppressed, and the user can carry the handle and the basket body together.

  The basket body is rotatable with respect to the handle in a rotation range from a starting point with the opening facing upward to an end point with the opening facing downward, and the basket body at the end point And a holding portion for holding a relative posture between the handle and the handle.

  By adopting such a configuration, it is possible to prevent the basket body from excessively rotating with respect to the handle, and it is possible to prevent problems such as wear due to excessive rotation. Further, since the posture of the basket body can be fixed with the opening portion directed downward, the basket body does not move unstable when the basket is shaken up and down with the handle. Therefore, the user can detach the dust bag more reliably by shaking the basket body with the posture in which the opening is downward.

  The handle may be movable in a direction approaching and separating from the basket body.

  With such a configuration, when the basket is taken out from the dust collection chamber, a gap can be formed between the handle and the dust collection bag by moving the handle upward (in a direction away from the basket body). Therefore, if a finger is put into this gap, the handle can be easily grasped, and the basket can be easily taken out from the dust collection chamber.

  Further, the relative rotation of the basket main body and the handle and the movement in the contact / separation direction may alternatively be realized.

  By adopting such a configuration, it is possible to limit complicated displacement such as moving while rotating, and to improve operability.

  Moreover, you may provide the urging | biasing part which urges | biases the said handle | steering-wheel in the direction away from the said basket main body.

  By setting it as such a structure, when the cover part of a cleaner main body opens, for example, a handle can be raised by urging | biasing force. Therefore, a gap can be formed between the dust bag and the handle, and it becomes easy to put a finger here and hold the handle.

  Further, with respect to the relative position of the handle with respect to the basket body, substantially between a position in a natural state where no external force acts and a position close to the basket body against the urging force by the urging portion. A dimension sufficient to insert the user's finger may be secured.

  By adopting such a configuration, when the basket is taken out, a gap can be formed between the dust bag and the handle, and it is easy to put a finger here to hold the handle. As such a dimension, for example, about 10 mm can be adopted.

  In addition, the handle may have a grip portion having different dimensions on one end side and the other end side in the rotation direction of the basket body.

  By adopting such a configuration, if the thumb is made to correspond to the short end and the other four fingers are made to correspond to the long end, the handle can be easily grasped.

  In addition, the handle includes a gripping portion that is spanned so as to connect pivot portions on both sides of the basket body, and a reinforcing portion that is provided in parallel to the grip portion so as to connect the pivot portions. May be.

  By adopting such a configuration, the rigidity of the handle gripped by the user is improved, so that a sense of stability during use is enhanced. Further, in the configuration in which the contact portion of the handle and the contacted portion of the basket body are in contact, the deformation of the handle due to the contact can be prevented, and the basket body can be more reliably deformed so that the opening is widened.

  Further, the basket body has a mouth plate support portion that supports the mouth plate forming the opening of the dust bag in a vertically placed state, and the handle is moved in a direction close to the basket body. The upper end portion of the mouth plate of the dust collection bag may have a pressing portion that presses the dust collection chamber in the upstream direction of ventilation.

  By adopting such a configuration, the dust-mixed air flowing into the dust collection chamber can be more reliably taken into the dust collection bag.

  An electric dust collector according to the present invention is an electric dust collector including a cleaner body having a dust chamber, wherein any of the baskets described above is detachably attached to the dust chamber, The main body of the vacuum cleaner is provided with a lid for opening and closing the dust collection chamber, and the lid is inflated to prevent expansion of the dust collection bag set in the basket with the dust collection chamber closed. Is provided.

  With such a configuration, an extra space can be formed in the dust collection chamber, so that the extra space can be used as an air flow path when the vacuum cleaner is driven. For example, since a large amount of dust is stored in the dust collection bag near the downstream end of the dust collection chamber, the air flow in this portion is stagnant. Therefore, if the expansion of the dust bag is prevented in areas other than this portion and an excess space is formed, a smooth air flow can be maintained and the dust collection performance can be maintained high. In addition, if a surplus space is formed in the vicinity of the handle, it becomes easy to put fingers between the handle and the dust bag.

  According to the basket for an electric dust collector and the electric dust collector according to the present invention, the dust bag can be easily removed.

When the lid 2 is opened, the dust collection chamber 11 and the machine chamber 12 are exposed, and the basket 20 can be attached to and detached from the dust collection chamber 11 through the large opening 14.

(Appearance structure of basket)
FIG. 3 is an external perspective view showing the configuration of the basket 20. As shown in FIG. 3, the basket 20 includes a basket body 20A and a handle 20B.

  The basket body 20 </ b> A includes a support wall that houses and supports the dust collection bag 21. This support wall has a pair of left and right side surface support walls 30 that support the dust bag 21 from both sides, and a bottom surface support wall 31 that supports the dust bag 21 from below. Of these, the left and right side support walls 30 have inner surfaces recessed outwardly to the left and right so as to wrap and support the bag body 21c of the expanding dust collecting bag 21, and allow air that has passed through the bag body 21c to pass therethrough. A plurality of small-diameter vent holes 30a are formed through the inside and outside. Further, the upper end portions of the left and right side support walls 30 are formed so as to be inclined forward so as to be positioned downward from the rear portion toward the front portion. In other words, the side surface support wall 30 is configured such that the height dimension from the lower end portion to the upper end portion becomes smaller from the rear portion toward the front portion.

  The bottom surface support wall 31 connects the lower end portions of the left and right side surface support walls 30 and has deformation portions (see deformation portions 73 and 77 in FIG. 10) described later. The basket body 20 </ b> A is configured to support the dust collection bag 21 from the left and right and the lower side by the left and right side support walls 30 and the bottom support wall 31, and between the upper portions of the left and right side support walls 30, the dust collection bag 21. A basket opening 33 is formed through which the dust bag 21 passes when the bag is attached and detached.

  Left and right mouth plate support portions 34 that support the mouth plate 21b of the dust bag 21 are provided in the front portion of the basket body 20A. The mouth plate support portion 34 is formed as a portion that is bent in a crank shape and extends in the center direction on the left and right sides from the front end portion of the side support wall 30 curved in the center direction on the left and right. More specifically, each of the left and right mouth plate support portions 34 includes a side wall portion 34a extending forward by a predetermined dimension from the front end portion of the side surface support wall 30, and from the front end portion of the side wall portion 34a to the left and right central directions. And a front wall portion 34b extending toward the front. The mouth plate 21b (see FIG. 2) of the dust bag 21 is supported in a vertically placed state so as to be sandwiched between the left and right side wall portions 34a, and is supported from the front by the front wall portion 34b.

  Further, the left and right front wall portions 34b of the mouth plate support portion 34 are spaced apart by a small dimension L1 between the lower portions thereof, and are larger than the dimension L2 between the upper portions and larger than the diameter of the dust collecting holes 21a of the mouth plate 21b. Only separated. Therefore, in the state where the dust bag 21 is set in the basket body 20A, the front wall portion 34b supports the left and right portions and the lower portion of the mouth plate 21b without closing the dust collection hole 21a (in an exposed state). . In addition, since the mouthplate support part 34 is set to the height dimension smaller than the mouthplate 21b, when the dust bag 21 is set to the basket main body 20A, the upper part of the mouthplate 21b is the mouthplate support part 34. Projecting upward.

  FIG. 4 is a plan view of the handle 20B. As shown in FIGS. 3 and 4, the handle 20B includes an upper support portion 40 that supports the upper portion of the dust bag 21, a corner support portion 41 that supports the front and left and right portions of the dust bag 21, and Arm portions 42 that extend downward from the left and right end portions of the upper support portion 40 and are connected to the basket body 20A at the lower portion are provided.

  The upper support part 40 has a grip part 43 that extends over the basket opening 33 from side to side. The grip portion 43 has a strip shape with a substantially constant front-rear width, and the length dimensions of the front and rear end sides are different. Specifically, as shown in FIG. 4, the length dimension L4 of the rear side edge 43b is set larger than the length dimension L3 of the front side edge 43a. Therefore, when the user attaches or removes the basket 20 in which the dust bag 21 is set to or from the dust collection chamber 11, the thumb of the hand is made to correspond to the short front side edge 43a, and the long rear side If the remaining four fingers are made to correspond to the end side 43b, the grip portion 43 can be easily gripped.

  The upper support part 40 has a reinforcing part 44 provided in parallel with the grip part 43. The reinforcing portion 44 has a strip-like shape that is bridged to the left and right in the same manner as the grip portion 43, and its main surface is oriented in the front-rear direction. On the other hand, the gripping portion 43 described above has a main surface oriented in the vertical direction. Thus, the handle 20B is improved in rigidity by arranging the grip portion 43 and the reinforcement portion 44 having different main surface orientations in parallel.

  Further, in a state where the basket 20 is mounted in the dust collection chamber 11, the gripping portion 43 supports the upper surface of the dust collection bag 21 that expands by suction, and the reinforcing portion 44 supports the upper rear surface. A handle rear opening 45 is provided between the grip 43 and the reinforcement 44. Accordingly, when the user grips the handle 20B, the grip portion 43 can be gripped by inserting four fingers other than the thumb through the handle rear side opening 45.

  The corner support portion 41 is integrally extended forward from the left and right portions of the upper support portion 40 and the upper portion of the arm portion 42, and the front and upper left and right portions of the dust collection bag 21 that is inflated by intake air. Support as if covering. A rectangular handle front opening 46 is formed between the grip 43 and the left and right corner supports 41.

(Coupling mechanism)
The basket body 20A and the handle 20B are connected via a coupling mechanism 50. As will be described below, the coupling mechanism 50 allows both of them to relatively slide and rotate.

  FIG. 5 is an enlarged view of the left connecting mechanism 50. The connecting mechanism 50 is configured to connect the left and right side support walls 30 of the basket body 20A and the left and right arm portions 42 of the handle 20B, respectively. Since the left and right coupling mechanisms 50 are symmetrical to each other, only the left coupling mechanism 50 shown in FIG. 5 will be described below. As shown in FIG. 5, the coupling mechanism 50 has a shaft portion 51 projecting outward from the side support wall 30 of the basket body 20A and a slit 52 formed in the lower portion of the arm portion 42 of the handle 20B. doing.

  The base portion of the shaft portion 51 has a substantially semicircular shape lacking the front portion in a side view, and the peripheral surface thereof is a flat surface 51a along the vertical direction positioned on the front side and an arc positioned on the rear side. It is comprised by the surface 51b. The distal end portion of the shaft portion 51 has a side view shape similar to that of the base portion, but in addition to this, a protruding portion 51c protruding in a radial direction from a part of the arc surface 51b is provided.

  The slit 52 extends in a straight line in the vertical direction, and has a width that is substantially the same as the width of the base portion (front-rear width) of the shaft portion 51. The upper end portion 52 a of the slit 52 is formed to have an arcuate contour so as to match the shape of the base portion of the shaft portion 51. A circular bearing hole 52 b is formed at the lower end of the slit 52. The bearing hole 52 b is a circular shape having substantially the same diameter as the diameter defining the circular arc surface 51 b of the shaft portion 51, and is therefore wider than the slit 52.

  With such a configuration of the coupling mechanism 50, the basket body 20A and the handle 20B can selectively perform sliding in the direction (up and down direction) relatively approaching and moving away from each other and rotation in the front-rear direction. ing.

(Slide mode)
FIG. 6 is a view showing a state in which the handle 20B slides with respect to the basket body 20A. As shown in FIG. 6, the handle 20 </ b> B is slidable in the vertical direction within a range (sliding range; distance D <b> 1) in which the shaft portion 51 moves in the slit 52. Further, as described above, the front portion of the shaft portion 51 is provided with the flat surface 51a along the vertical direction, and the front side edge portion of the slit 52 in contact therewith also extends linearly along the vertical direction. Therefore, when the handle 20B slides in the vertical direction, back and forth rattling is prevented.

  The basket 20 is provided with a biasing portion 60 that biases the handle 20B in a direction (upward) away from the basket body 20A. Specifically, as shown in FIG. 6, an elastic body 61 is provided in a state in which the elastic body 61 is accommodated in the accommodating portion 62 at the upper rear side of the left and right side support walls 30 of the basket body 20 </ b> A. In the present embodiment, the elastic body 61 uses a coil spring and is arranged in a posture that can be expanded and contracted in the vertical direction. On the other hand, a pressing portion 63 that is opposed to the elastic body 61 from above is provided at the left and right lower portions of the upper support portion 40 of the handle 20B and at the rear portion of the arm portion.

  When the handle 20B is in the middle position of the slide range (hereinafter referred to as “equilibrium position”), the urging unit 60 is in contact with the upper end of the elastic body 61 and the weight of the bundle 20B and the elastic body 61 It is configured to balance the biasing force. Therefore, as shown in FIG. 6, in the slide range (distance D1), the lower section (distance D2) in which the handle 20B is urged upward by the elastic body 61, and the elastic body 61 and the pressing portion 62 are separated. There is an upper section (distance D3) in which the handle 20B can be slid in a state where the urging force is not applied. In the present embodiment, the distance D2 = 15 mm is set for the lower section, and the distance D3 = 20 mm is set for the upper section.

  In the vacuum cleaner 1 according to the present embodiment, when the basket 20 is attached to the dust collection chamber 11 and the lid 2 is opened, the handle 20B is in the “balance position” (“balance” in FIG. 6). Status ”). When the lid 2 of the vacuum cleaner 1 is closed, the handle 20B is pressed downward from the equilibrium position by the inner surface of the lid 2 and reaches the “contracted position” near the lower end of the slide range (in FIG. 6). (See “Shrinkage”). On the other hand, when the user grasps the grip 43 and lifts the basket 20 from the equilibrium position, the handle 20B slides upward and reaches the “extension position” at the upper end of the slide range. 21) is in a state of being suspended from the handle 20B (see “extension state” in FIG. 6). Accordingly, at this time, the entire basket 20 is pulled out from the dust collection chamber 11.

  FIG. 7 is a cross-sectional view of the basket 20 in which the dust bag 21 is set, and shows a state (a contracted state and a balanced state) before and after the lid 2 is opened. As shown in FIG. 7, in the basket 20 attached to the dust collecting chamber 11 and being in a contracted state, when the cover 2 of the cleaner 1 is opened, the handle 20B is automatically moved by the distance D2 by the urging force of the elastic body 62. To reach an equilibrium position. Therefore, even when the dust bag 21 is in the maximum inflated state by the intake air, when the basket 20 is taken out, the handle 20B is raised and a gap with a height dimension D2 is formed between the upper surface of the dust bag 21. As a result, the user can easily grasp the grip portion 43. For this reason, in this Embodiment, the dimension which can insert a user's finger | toe is assumed as a setting reference | standard of distance D2.

  Incidentally, the basket 20 includes guides (an upper guide 65 and a lower guide 66) for preventing rattling when the handle 20B is slid up and down, in addition to the above-described coupling mechanism 50.

  The upper guide 65 is formed integrally with the accommodating portion 62 of the elastic body 61. That is, as shown in FIG. 6, the accommodating portion 62 has a substantially rectangular shape when viewed from the side, and its front end surface 65a abuts against the rear end surface of the arm portion 42 of the handle 20B so as to be slidable from the rear. ing. Further, a support piece 65b extends forward from the lower portion of the accommodating portion 62, and the support piece 65b abuts against the outer surface of the arm portion 42 so as to be slidable from the outside. The front end surface 65a and the support piece 65b form an upper guide 65 positioned above the shaft portion 51, and guide the arm portion 42 from the rear side and the outer side during vertical sliding.

  On the other hand, the side support wall 30 of the basket body 20 </ b> A is provided with a lower guide 66 positioned below the shaft portion 51. The lower guide 66 has a guide wall 66a extending in the vertical direction so as to follow the trajectory of the rear end surface when the arm portion 42 slides up and down. A reinforcing rib 66b is provided at the rear of the guide wall 66a to connect the back surface of the guide wall 66a and the outer surface of the side support wall 30. Such guide walls 66a and reinforcing ribs 66b form a lower guide 66 located below the shaft portion 51, and guide the arm portion 42 from the rear when sliding up and down.

  Such guides 65 and 66 can stably guide the handle 20B while it slides between the contracted position and the extended position, thereby preventing the handle 20B from rattling. However, the addition of such a guide is arbitrary, and even if it is added, only one of the upper guide 65 and the lower guide 66 may be added. Further, when the upper guide 65 is added, the support piece 65b may be omitted.

  The lower part of the arm part 42 has an arc shape with a predetermined diameter D4. The upper end of the guide wall 66a of the lower guide 66 is located at least a distance D4 away from the center of the shaft portion 51. In other words, when the handle 20B is in the extended position, the shortest distance between the lower guide 66 and the shaft portion 51 is set to a dimension D4 or more. Therefore, the lower guide 66 can guide the arm portion 42 when sliding up and down, and does not hinder the rotation of the arm portion 42 around the shaft portion 51 when the handle 20B is in the extended position. .

(Rotation mode)
FIG. 8 is a view showing a manner in which the handle 20B rotates with respect to the basket body 20A. As shown in FIG. 8, the basket body 20 </ b> A and the handle 20 </ b> B are rotatable when the handle 20 </ b> B is in the extended position, that is, when the shaft portion 51 is positioned in the bearing hole 52 b at the lower end of the slit 52. Yes.

  The rotation range is a range from the posture B1 where the handle 20B is located above the basket body 20A to the posture B3 located below through the posture B2 located in front of the basket body 20A. From the viewpoint of rotating the basket body 20A while fixing the handle 20B, the posture B2 with the basket opening 33 facing backward is changed from the attitude (starting point) B1 with the basket opening 33 of the basket body 20A facing upward. After that, it can be rotated in a range reaching a downward posture (end point) B3.

  The limit on the posture B1 side in this rotation range is defined by the rear end surface of the arm portion 42 coming into contact with the front end surface 65a of the upper guide 65. On the other hand, a holding portion 67 that holds the basket body 20A and the handle 20B in the posture B3 is projected from the lower portion of the side support wall 30 of the basket body 20A. The limit on the posture B3 side in the rotation range is defined by the corner support portion 41 of the handle 20B coming into contact with the holding portion 67. As a result, the rotation range of the handle 20B relative to the basket body 20A is approximately 165 degrees in the present embodiment. However, the specific numerical value of the rotation range that can be adopted is not limited to this, and can be appropriately selected.

  FIG. 9 is a side view of the basket 20 for explaining a configuration for preventing the basket body 20A from rotating naturally. As shown in FIG. 9, the center of gravity G is set in the basket body 20 </ b> A at a position offset forward from the shaft portion 51. Therefore, a moment is generated in the basket body 20A in the counterclockwise direction around the shaft portion 51 due to its own weight, and the basket body 20A tends to rotate in a forward tilting direction. However, since the front end surface 65a of the upper guide 65 is in contact with the rear end surface of the arm portion 42, the basket body 20A integrated with the upper guide 65 is locked by the upper guide 65 and rotated in a forward tilting direction. Be blocked. As described above, the basket body 20A stably faces the basket opening 33 upward by the center of gravity G offset from the shaft portion 51 and the upper guide 65 serving also as a locking portion locked to the arm portion 42. Can be maintained.

(Basket body widening structure)
By the way, in the basket 20 according to the present embodiment, the basket opening 33 is expanded in a state where the basket 20 is taken out from the dust collecting chamber 11, and the dust collecting bag 21 can be easily taken out from the basket body 20A. Below, the structure (mouth opening structure) for the basket opening part 33 to expand in this way is demonstrated.

(Deformation part)
FIG. 10 is a view showing a configuration for expanding and contracting the basket opening 33, and shows a plan view and a cross-sectional view of the bottom support wall 31 of the basket body 20A. FIG. 11 is a rear view showing a state in which the basket opening 33 spreads, and shows a basket body 20A in a normal state (a state before spreading) and a basket body 20A in a spread state.

  As shown in FIG. 10, the bottom surface support wall 31 of the basket body 20 </ b> A has a front bottom wall 71 located on the front side across the horizontally long gap 70 and a rear bottom wall 75 located on the rear side. Yes. Each of the front bottom wall 71 and the rear bottom wall 75 has a belt-like shape with a constant width dimension in the front-rear direction, and the rear bottom wall 75 has a larger width dimension than the front bottom wall 71.

  The front bottom wall 71 has left and right flat plate portions 72 extending in the horizontal direction, and a front deformation portion 73 is provided therebetween. The front deformation portion 73 has a U-shaped cross section (in this embodiment, an inverted U shape that is convex above the height dimension H1), and is integrally formed with the left and right flat plate portions 72 with resin or the like. ing. With such a configuration, the front deformation portion 73 has low rigidity (high flexibility). Accordingly, the front bottom wall 71 is easily deformed at the front deformation portion 73, and can be curved so that the left and right portions are positioned below the center portion (see the arrows shown in the AA cross-sectional view in FIG. 10). ).

  As shown in the plan view, the left and right flat plate portions 72 of the front bottom wall 71 are connected to the lower portions of the left and right front wall portions 34 b of the mouth plate support portion 34. Therefore, the deformation of the left and right flat plate portions 72 is inhibited by the front wall portion 34b. On the other hand, the lower portions of the left and right front wall portions 34b are separated by a dimension L1 (see FIG. 3), and the front deformation portion 73 is in a free state not connected to the front wall portion 34b. Accordingly, the front bottom wall 71 is configured to be more easily deformed by the front deformation portion 73 than by the flat plate portion 72.

  The rear side bottom wall 75 is provided with rear side deformed portions 77 on the left and right sides of the central flat plate portion 76. These rear deformation portions 77 also have a U-shaped cross section (in this embodiment, a reverse U shape that is convex above the height dimension H2), and are integrally formed with the flat plate portion 76 by resin or the like. ing. Further, the flat plate portion 76 is formed with a concave portion 76a having a circular shape in a bottom view. Since the stepped portion on the periphery of the recess 76a has an arc shape when viewed from the bottom, the flat plate portion 76 has high rigidity (low flexibility).

  Accordingly, the rear bottom wall 75 is easily deformed at the left and right rear deformation portions 77, and can be curved so that the left and right portions are positioned below the central portion (in the cross-sectional view along the line BB in FIG. 10). (See the displayed arrow). In addition, in the basket body 20 according to the present embodiment, as shown in FIG. 10, the front deformation portion 73 (height dimension H1) has a vertical dimension that is higher than the rear deformation portion 77 (height dimension H2). It is set to be large. Therefore, the front bottom wall 71 is less rigid than the rear bottom wall 75 and is easily bent. Therefore, when the dust bag 21 is discarded, even if the friction between the basket body 20 and the mouth plate 21b is larger than the friction between the basket body 20 and the bag body 21c, the front portion of the basket body 20 is disposed. And the mouth plate 21b can be more reliably detached from the basket body 20.

  With this configuration, as shown in FIG. 11, the basket opening 33 can be changed to a state (lower view) that is greatly expanded as compared to the normal state (upper view). That is, in the basket body 20A, when the bottom surface support wall 31 is curved, the left and right side surface support walls 30 are opened so that the separation distance increases toward the upper side. As a result, the basket opening 33 is deformed from a normal state (opening width L5) to a state having a larger opening width L6 (lower diagram).

(Synchronization of rotation and widening)
As described above, the basket 20 has the basket opening 33 widened. However, the basket 20 according to the present embodiment is further linked to the rotation of the basket body 20A relative to the handle 20B. Is configured to spread. Hereinafter, the structure which implement | achieves the interlocking | linkage of such rotation and a mouth opening is explained in full detail.

  FIG. 12 is a drawing for explaining a configuration in which the rotation of the basket body 20A and the opening of the basket opening 33 are interlocked, and shows a front view, a bottom view, and a side view of the basket 20. FIG. 13 is a perspective view showing a state in which the basket main body 20A is rotated with respect to the handle 20B and the basket opening 33 is expanded. As shown in FIG. 12, the left and right corner support portions 41 of the handle 20B are provided with contact portions 80, and the bottom support wall 31 of the basket body 20A has contacted portions 81 corresponding to the contact portions 80. Is provided. Of these, the left and right contact portions 80 are formed as corner portions that protrude forward and downward in the present embodiment, and are disposed on the left and right sides at a predetermined distance L7.

  On the other hand, the abutted portion 81 is formed as a surface directed to the left and right outer sides, and compared to the interval L8 of the front side portion (downstream portion in the turning direction), the rear side portion (upstream in the turning direction) The distance L9 between the side portions) is larger. Further, the interval L7 of the contact portion 80 is set to be equal to or greater than the interval of the front portion of the contacted portion 81 and less than the interval L9 of the rear portion of the contacted portion 81. Furthermore, the contacted portion 81 extending in the front-rear direction has an arc shape centered on the shaft center of the shaft portion 51 when viewed from the side, and the diameter L10 of the contacted portion 81 is a bearing hole 52b of the handle 20B. Is substantially the same as the dimension L11 from the center to the contact portion 80.

  In the basket 20 having such a configuration, when the basket body 20A is rotated with respect to the handle 20B, the abutting portion 80 is covered in a predetermined state (first opening state) in which the basket opening portion 33 is inclined rearward and downward. Contact the front portion of the contact portion 81. More specifically, the left and right contact portions 80 contact each other so as to sandwich the contacted portion 81 from the left and right. When the basket body 20A is rotated so that the basket opening 33 is further directed downward from this state, the contact portion 80 slides along the contacted portion 81.

  Here, the interval L7 of the contact portion 80 is constant, whereas the interval of the contacted portion 81 increases from the interval L8 to the interval L9 toward the rear portion. Accordingly, a force acts on the contacted portion 81 from the contact portion 80 toward the center in the left-right direction, so that the deformation portions 73 and 77 are deformed and the basket body 20A is deformed as shown in FIG. . As a result, when the contact portion 80 reaches the rear end portion of the contacted portion 81, the basket opening 33 spreads to the maximum distance L9. When the contact portion 80 reaches the rear end portion of the contacted portion 81, the handle 20B contacts the holding portion 67 (FIG. 8) of the basket body 20A, and this posture is maintained.

  With the configuration as described above, the basket 20 according to the present embodiment, for example, when the user grips the grip portion 43 of the handle 20B with the right hand and rotates the basket body 20A with the left hand, the basket opening portion 33 moves downward. The opening size increases in the state of facing. Therefore, since a gap is generated between the dust bag 21 and the inner surface of the side support wall 30, the dust bag 21 falls from the basket body 20 due to its own weight and is detached even if it is not manually gripped. Thus, the dust bag 21 can be easily discarded.

  Moreover, in the case of the basket body 20 according to the present embodiment, the front deformation portion 73 is provided at the center portion in the left-right direction of the bottom support wall 31, and the rear deformation portion 77 is provided separately from the left and right portions of the bottom support wall 31. It has been. In other words, as shown by a broken line VL in the plan view of FIG. 10, the front side deformation portion 73 and the rear side deformation portion 77 form a triangle with the front side at the top and the rear side at the bottom side in the bottom surface support wall 31. Has been placed. Accordingly, the bottom surface support wall 31 is formed with a fold line (as along the broken line VL) from the front center portion to the rear left and right portions, and the basket body 20A is easily opened in conjunction with the rotation of the handle 20B. It has become.

(Mouth plate pressing part)
FIG. 14 is a side view of the basket 20 showing a configuration in which the handle 20B supports the mouth plate 21b of the dust bag 21 when the basket 20 is housed in the dust chamber 11 (a contracted state). As shown in FIG. 14, the corner support portion 41 of the handle 20B has an upper end portion of the mouth plate 21b of the dust collection bag 21 in the upstream direction of ventilation in the dust collection chamber 11 (ie, the direction of the intake hole 13; FIG. 14). And a guide portion 41b for guiding the mouth plate 21b to the press portion 41a.

  More specifically, the pressing portion 41a has a configuration defined by a vertical edge extending along the vertical direction and a horizontal edge extending forward from the upper end thereof, and is supported only by the mouth plate support 34. It is located slightly closer to the front than the mouth plate 21b in the state of being made. The guide portion 41b is formed as an edge extending obliquely upward and forward, and its upper end is connected to the vertical edge portion of the pressing portion 41a, and its lower end is connected to the contact portion 80 described above. Yes.

  By such a pressing part 41a and the guiding part 41b, the mouth plate 21b of the dust bag 21 can be urged toward the intake hole 13 (see FIG. 2). That is, when the basket 20 is attached to the dust collection chamber 11 (“equilibrium state” in FIG. 14) and the lid portion 2 is closed, the handle 20B pressed against the inner surface of the lid portion 2 is lowered to a contracted state. At this time, the upper end portion of the mouth plate 21b slides along the guide portion 41b as the handle 20B is lowered, and is pushed forward according to the inclined shape of the guide portion 41b. When the handle 20B reaches the contracted position, the upper end of the mouth plate 21b is supported from behind and above while being urged forward by the pressing portion 41a.

  Accordingly, the state in which the mouth plate 21b is brought close to the suction hole 13 (or the state in which the mouth plate 21b is in contact with the front wall portion 34b of the mouth plate support portion 34) is maintained regardless of the pressure of the intake air. be able to. Therefore, the dust-mixed air sucked through the intake hole 13 can be taken into the dust bag 21 more reliably.

(Expansion prevention part)
FIG. 15 is a perspective view showing the expansion preventing portion 90 provided on the lid portion 2 of the cleaner body 3. FIG. 16 is a front cross-sectional view of the cleaner body 3 in a state where the lid 2 having the expansion preventing unit 90 is closed. As shown in FIG. 15, an expansion preventing portion 90 is provided at the front end lower portion of the lid portion 2. The expansion preventing portion 90 has a ventilation channel 91 extending from the lower portion to the upper portion while having a block-like appearance. Further, the expansion preventing portion 90 is disposed so as to be fitted into the handle front side opening portion 46 (see FIGS. 3 and 4) of the handle 20 </ b> B of the basket 20 when the lid portion 2 is closed.

  When such an expansion preventing portion 90 is provided, as shown in FIG. 16, a part of the upper portion of the dust collection bag 21 is prevented from expanding, and an air flow route through the ventilation channel 91 can be secured. it can. That is, the air taken into the dust bag 21 from the intake hole 13 passes through not only the route passing through the rear part of the dust bag 21 but also the route passing through the upper part, and the predetermined exhaust port of the cleaner body 3. (Not shown) can be discharged. Therefore, even if a large amount of dust accumulates in the rear part of the dust collection bag 21, it is possible to efficiently collect the dust without reducing the suction force.

  In addition, since the upper part of the dust bag 21 is pressed downward and the expansion is prevented, when the basket 20 is taken out to discard the dust bag 21, the gap between the grip 43 and the upper part of the dust bag 21 It also makes it easier to put your fingers in.

(Modification)
FIG. 17 is a side view of the basket 20 for explaining another configuration for preventing the basket body 20A from rotating naturally. In the example shown in FIG. 17A, a friction portion 100 that restricts relative rotation of the handle 20B is provided on the side support wall 30 of the basket body 20A. The friction portion 100 can be made of a material having a large coefficient of static friction such as synthetic rubber, for example, and is arranged so that the inner surface of the arm portion 42 is in sliding contact with the relative rotation of the basket body 20A and the handle 20B. Has been. In FIG. 17A, the friction part 100 is provided on the circumference centering on the shaft part 51.

  In the example shown in FIG. 17B, the interference protrusion 101 that temporarily interferes with the guide wall 66 a of the lower guide 66 is provided on the lower peripheral portion of the arm portion 42 that forms an arc shape. When the basket 20 is in the posture B1, the interference projection 101 is located on one side (one side around the shaft 51) with respect to the upper end of the guide wall 66a. Then, when the basket body 20A is slightly rotated backward from this posture B1, the interference protrusion 101 interferes with the guide wall 66a and overcomes the other end (around the shaft portion 51) with respect to the upper end of the guide wall 66a. To the other side).

  By providing the friction part 100 or the interference protrusion 101 as described above, the basket 20 can be stably held in the state of the posture B1. Note that the configuration shown in FIG. 17A or FIG. 17B may be replaced with the configuration shown in FIG. 9 described above, or any two or three may be used simultaneously. . Moreover, the friction part 100 shown to Fig.17 (a) does not need to be provided so that it may slidably contact with the arm part 42 in the whole rotation range. For example, it is good also as providing in one part so that rotation in the rotation area including the state which turned the basket opening part 33 upwards at least may be restrict | limited. Further, instead of providing the friction portion 100 on the basket body 20A, a friction portion such as a synthetic rubber may be provided on the arm portion 42 of the handle 20B at a portion facing the side support wall 30 of the basket body 20A.

  As described above, the basket 20 according to the present embodiment is a basket 20 for the dust bag 21 that is detachably attached to the dust chamber 11 of the vacuum cleaner 1, and the dust bag 21 is set. The basket body 20A includes a support wall (side support wall 30 and bottom support wall 31) that supports the dust collection bag 21, and opens upward in a state of being attached to the dust collection chamber 11. The basket opening 33 is configured so as to expand in a state where the basket opening 33 is removed from the dust collecting chamber 11. As a result, the basket opening 33 is expanded in a state where it is detached from the dust collection chamber 11 than in a state where it is mounted in the dust collection chamber 11. Accordingly, a gap is formed between the basket body 20A and the dust bag 21 and the frictional resistance therebetween is reduced, so that the dust bag 21 can be easily detached from the basket body 20A.

  The support wall (bottom support wall 31) has deformed portions 73 and 77 that deform so as to widen the basket opening 33. Thus, if the deformation | transformation part is defined, the whole shape of 20 A of basket main bodies after a deformation | transformation can also be estimated in a substantially constant shape. Therefore, it becomes easy to design the basket opening 33 to have a desired degree of opening, and the basket 20 from which the dust bag 21 can be easily removed can be realized more reliably. Further, the basket body 20A can be integrally formed by casting or the like so as to be a single component, and in this case, it is possible to suppress the occurrence of problems in the basket 20 due to fine dust.

  Moreover, it is good also as comprising the support wall (the side surface support wall 30 and the bottom face support wall 31) mentioned above with 2-3 structural members, and providing a deformation | transformation part in the connection location of each structural member. Also in this case, the overall shape of the basket body 20A after deformation can be estimated to be a substantially constant shape. Therefore, it becomes easy to design the basket opening 33 to have a desired degree of opening, and the basket 20 from which the dust bag 21 can be easily removed can be realized more reliably.

  Further, the handle 20B is pivotally supported on both sides of the basket body 20A so as to be rotatable, and spans above the basket opening 33. Accordingly, the user can easily take out the basket body 20A from the cleaner 1 with the handle 20B. In addition, it is possible to easily remove the dust bag 21 from the basket body 20A, such as holding the handle 20B with one hand and rotating the basket body 20A with the other hand to direct the basket opening 33 downward.

  Further, the handle 20B has a contact portion 80 that contacts the basket body 20A when the basket body 20A is rotated so that the basket opening 33 faces downward. When it rotates with respect to the handle | steering-wheel 20B so that 33 may face below, it has the to-be-contacted part 81 which contacts the contact part 80 of the handle | steering-wheel 20B. As the handle 20B and the basket body 20A rotate relatively, the contact portion 80 and the contacted portion 81 come into contact with each other, so that the basket opening 33 is expanded. Yes.

  With such a configuration, it is not necessary to separately perform an operation of rotating the basket body 20A so that the basket opening 33 faces downward and an operation of expanding the basket opening 33. That is, if the basket main body 20A is rotated, the basket opening 33 can be widened accordingly. Therefore, the dust collection bag 21 can be detached from the basket body 20A by an easier operation.

  As described above, the basket for an electrostatic precipitator and the electrostatic precipitator according to the present invention are preferably applied to the basket and the electrostatic precipitator that can easily remove the dust bag. Can do.
