<P>PROBLEM TO BE SOLVED: To provide a vacuum cleaner which facilitates abandoning of dust and has therefore enhanced user-friendliness. <P>SOLUTION: A dust collection box 8 comprises: a main body part 10 which opens a communication port 9 communicating with a hose to be put through from an intake port 2, and stores the dust; and a lid body part 14 which is journaled by the main body part 10 in an openable and closable manner and is provided with a filter 13 for removing the dust contained in the air to be sucked to the main body part 10 by driving an electric blower. The main body part 10 is formed in a substantially rectangular shape where the depth dimension 20 is made to be smaller than the width dimension 22 and the height dimension 21. Thus, the pressurizing and expanding force of the dust works in the opening center part direction (an abandoning direction) of the main body part 10 through the use of both side surface walls of the main body part 10, so that the dust compressed in the main body part 10 is discharged from the opening of the main body part 10 so as to be bend from the center part. Consequently, the separation of the compressed and collected dust from the main body part 10 is promoted to improve the abandoning of the dust. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a vacuum cleaner, and more particularly to a dust collection box of a vacuum cleaner.

The main body shape of the dust collection box of the conventional vacuum cleaner was formed in a substantially rectangular parallelepiped (for example, refer to Patent Document 1). The dust collection box of such a vacuum cleaner has a shape that makes it difficult to discard dust because the dust is compressed in the main body when the dust accumulated in the main body is discarded. there were.
JP 2005-318915 A

  However, in the above-described conventional configuration, the depth dimension from the communication port of the main body part that accumulates dust to the rear opening part (lid fitting part) is substantially the same as the other width dimension or height dimension. It has a substantially square shape. Therefore, when the lid is opened and the dust accumulated in the main body is discarded, it is difficult to discard the dust. This is because the dust sucked into the dust collection box by the suction air of the electric blower is accumulated only in the main body by the filter, but dust such as cotton dust is accumulated while being compressed by the suction of the electric blower. Become. After that, when the volume of the main body is accumulated to the vicinity of the full volume, dust such as compressed cotton dust generates a force that spreads in the direction of the side wall of the main body, but the side wall of the main body is fixed and does not spread. Since the dust remains compressed between both side walls, the shape of the main body close to a substantially rectangular parallelepiped shape accumulates due to the force of the dust spreading toward the side wall even when the lid is opened. It was difficult to dispose of dust.

  The present invention solves the above-described conventional problems, and an object thereof is to provide a vacuum cleaner that improves the disposal of dust collection waste by promoting the separation of dust accumulated in the dust collection box main body. And

  In order to solve the above-mentioned conventional problems, the vacuum cleaner of the present invention has a dust collection box, a main body portion that opens a communication port that communicates with a hose inserted from the suction port, and accumulates dust. The lid is configured so as to be openable and closable, and is provided with a lid portion that is provided with a filter for removing dust contained in the air sucked into the main body by driving the electric blower. The depth dimension is formed smaller than the other width dimension or height dimension.

  As a result, the accumulated dust tends to push and spread to both side walls of the main body, but the main body is formed in a substantially rectangular parallelepiped shape and its depth dimension is smaller than other width dimensions or height dimensions. For this reason, the force that the dust spreads out on both side walls of the main body is reversed in the direction toward the center of the main body opening (discarding direction), and the dust compressed in the main body is discharged from the main body opening so as to bend from the center. As a result, it is possible to promote separation of the compressed accumulated dust from the main body, and as a result, it is possible to improve dust disposal.

  The vacuum cleaner of the present invention can improve the discardability of dust collected in the dust collection box.

  A first aspect of the present invention is a dust collection box storage unit that detachably stores a suction port at a front portion and a dust collection box at a rear portion of the suction port, and an electric blower that stores an electric blower at a rear portion of the dust collection box storage unit. In the vacuum cleaner provided with a chamber, the dust collection box is pivotally supported by a main body portion that opens a communication port communicating with a hose inserted from the suction port and accumulates dust, and is openable and closable by the main body portion. And a lid portion provided with a filter for removing dust contained in the air sucked into the main body portion by driving the electric blower, and the main body portion is formed in a substantially rectangular parallelepiped shape and has a depth thereof. By forming the dimensions smaller than other width dimensions or height dimensions, the force of spreading dust by the both side walls of the main body is reversed in the direction toward the center of the main body (in the direction of disposal) and compressed in the main body. Dust is in the center Come to be discharged from the main opening so et folded flex, can promote the waste away from the body portion of the compressed accumulated dust, result, it is possible to improve the disposability of dust.

  According to a second invention, in addition to the effects of the first invention, the depth dimension of the main body portion is set to a dimension of 1/3 or less of the other width dimension or height dimension in the first invention. The dust box itself can be reduced in size and weight.

  According to a third invention, in the first invention, the depth dimension of the main body is set to 1/3 or less of the other width dimension or height dimension and 55 mm or less, so that the compressed accumulated dust is reduced. The dust separation from the main body can be stably promoted, and as a result, the dust disposal property can be further improved. Further, the dust collection box itself can be reduced in size and weight.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, the side wall of the main body portion is inclined in a direction spreading toward the lid body side, whereby dust compressed in the main body portion is more opened to the main body portion opening side. Since it can be bent in the discharge direction, it is possible to further promote separation of dust, and as a result, it is possible to further improve dust disposal.

  According to a fifth invention, in any one of the first to third inventions, in the lid portion, a thin plate formed in a mesh or a porous shape and a filter pleated on the downstream side of the thin plate are disposed. In addition to the effect of the first invention, the structure that is pivotally supported on the main body part can separate coarse dust and fine dust with a thin plate, and can suppress clogging of the downstream filter. The thin plate and the filter can be securely attached to the main body. Further, when the collected dust is discarded, it can be easily discharged.

  6th invention is the filter body by which the cover body part A holding the thin plate formed in the mesh or the porous in any one 1st-3rd invention, and the pleat processing was carried out to the downstream of this cover body part A The lid parts A and B are respectively provided so that the lid parts A and B are pivotally supported by the body part so as to be openable and closable, and are formed on concentric shafts. In addition to the effects of the invention, the thin plate and the filter can be easily maintained.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
A first embodiment of the present invention will be described with reference to FIGS.

  As shown in FIGS. 1 and 2, a vacuum cleaner main body 1 includes a dust collection box housing 3 having a suction port 2 at the front and an electric blower chamber (not shown) having an electric blower (not shown) at the rear. The suction port 2 includes a vacuum cleaner main body 1 and a hose (not shown) air tight packing A4. The upper part of the dust collection box housing 3 is open, and a packing B5 is arranged on the entire upper end of the opening. Reference numeral 6 denotes a dust collection box storage cover that is rotatably provided with the rear portion of the cleaner body 1 as a fulcrum, and covers the upper opening of the dust collection box storage 3. The dust collection box storage unit lid 6 has a tight rib 7 that is substantially the same shape as the packing B5 and is in tight contact with the packing B5 when the dust collection box storage unit lid 6 is closed. Yes. The dust collection box storage unit 3 is configured so that the dust collection box 8 can be detachably stored. The dust collection box 8 has a main body 10 provided with a communication port 9, a lid A 12 holding a mesh or porous thin plate 11 behind the main body 10, and pleating on the downstream side thereof. A lid B14 that holds the filter 13 is held by a bearing 15 formed in the main body 10 so as to be rotatable and freely openable and closable.

  Note that the thin plate 11 and the filter 13 may be integrated and held in the lid portion.

  Further, as shown in FIG. 2, the lid A12 and the lid B14 are held by a concentric shaft. The lid body A12 and the lid body B14 are fixed to the main body portion 10 when the claw 17 of the main body portion 10 is hooked on the locking portion 16 of the lid body B14, and are in a form in use. At this time, the main body 10 and the lid B14 are airtight by the tight packing A18 formed around the outer periphery of the lid A12. The air tightness between the dust collection box 8 and the dust collection box storage 3 is tight by the packing A4 and the main body 10 on the front and the tight packing B19 formed on the wall 6 of the dust collection storage and the cover B14 on the rear. It has been done.

  3 and 4 show the dust collection box 8, in which the claw 17 is removed and the lid A12 and the lid B14 are opened. The main body 10 has a relationship between the depth dimension 20 from the communication port 9 to the surface where the lid A12 contacts in the closed state, the height dimension 21 from the bottom surface of the main body to the top, and the width dimension 22. 21 or less than 1/3 of the width dimension 22 and the main body 10 is formed in a substantially rectangular parallelepiped shape.

  About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  As shown in FIG. 1, dust and air pass through the suction port 2 and the communication port 9 and reach the main body 10 by suction air from an electric blower (not shown). Thereafter, the coarse dust 23 in the sucked dust is collected by the mesh 11 formed on the lid A12 or the thin plate 11 formed porous. The fine dust 24 and air pass through the thin plate 11 formed in a mesh or porous, and then the fine dust 24 is collected by the pleated filter 13 of the lid B14, and only the air is in the electric blower chamber (not shown). ) Through the vacuum cleaner body 1. Thus, the coarse dust 23 and the fine dust 24 are collected by the respective filters. Here, the main body 10 collects a large amount of coarse dust 23, that is, dust containing a large amount of cotton dust and fibers.

  As shown in FIG. 5, when the coarse dust 23 is fully collected in the main body 10, the coarse dust 23 collected while being compressed by the suction of the electric blower will spread to the side wall side of the main body 10. (Solid arrow). When the lid A12 and the lid B14 are opened in order to discard the collected dust, the dust tends to spread to the side wall of the main body 10 but the side wall of the main body 10 does not spread. Will remain. However, when the depth dimension 20 is set to 1/3 or less of the height dimension 21 or the width dimension 22, the force of pushing and spreading by compression is opposite to the force of spreading dust by the side walls of the main body. Since the dust that has been compressed in the body part is bent from the center part (dotted line arrow) and the dust is bent from about the center, The separation of dust from the inner surface of the part 10 can be promoted and can be discarded outside the main body part 10.

  Thus, by making the depth dimension 20 equal to or less than 1/3 of the height dimension 21 or the width dimension 22, it is possible to improve the discardability of dust by conversely using the fact that dust is compressed and accumulated. Is. Further, by shortening the depth dimension 20, the size of the dust collection box 8 and the cleaner body 1 itself can be simultaneously reduced in size and weight.

  Furthermore, by setting the depth dimension 20 to 1/3 or less of the height dimension 21 or the width dimension 22 and 55 mm or less, further folding of the dust can be promoted, and the discardability can be further improved.

  Also, as shown in FIG. 4, the side wall is inclined in a direction in which both side walls of the main body portion 10 extend from the surface of the communication port 9 toward the lid body side, and the angle is configured to be 10 ° or more. Since the compressing force provides an angle on both side walls, a backward force component is generated, and the dust disposal property can be improved.

  As described above, the vacuum cleaner according to the present invention can easily dispose of dust, greatly improves the usability, and is particularly useful for home and business vacuum cleaners.
