Description

  The present invention relates to a vacuum cleaner.

In recent years, vacuum cleaners with low noise and low noise have been desired. However, on the other hand, the suction force is also an important function, and it is not desirable to reduce the noise by reducing the power of the electric blower.
Moreover, it is known that the vibration of the electric blower built in the vacuum cleaner becomes vibration noise generated by propagating to the vacuum cleaner body and the atmosphere. As measures against vibration noise, there are a method for suppressing the generation of vibration from the electric blower that is a vibration source and a method for reducing propagation of vibration from the electric blower.
As a method of reducing the propagation of vibration from the electric blower, a method of holding the electric blower using a vibration preventing member that suppresses vibration between the case that houses the electric blower and the electric blower is generally used (for example, a patent Reference 1).

A lock member 13 c that is engaged with the front end of the hose port 21 and is locked is provided on the back surface of the dust case cover 13.

  A hinge portion 12b that rotatably supports the dust case cover 13 is formed in the vicinity of the exhaust cover 14 at the upper portion of the upper case 12. The dust case cover 13 is configured to be opened until it is directed upward in the vertical direction.

  The dust collection unit 19 communicates with a hose connection port 21b formed in the hose port 21 and also communicates with a space in which the electric blower 15 (see FIGS. 2 and 8) is accommodated via a filter 19b. In the present embodiment, a paper pack type is described as an example, but the present invention can also be applied to a cyclone type electric vacuum cleaner.

FIG. 4 is a rear view of the cleaner body.
As shown in FIG. 4, large-diameter wheels 20 a and 20 a are rotatably attached to the left and right sides of the rear portion of the lower case 11. A wheel 20b whose direction can be changed is attached to the lower surface of the lower case 11.

  The exhaust port 14d formed in the exhaust cover 14 has a plurality of slit-shaped holes 14d1 and is arranged in parallel to each other. Further, the exhaust port 14d is formed asymmetrically from the upper part of the curved outer surface 14a of the exhaust cover 14 to the left end. The plug outlet 14c is formed so as to protrude from the right end of the outer surface 14a, and has a hole that opens to the right and rear.

FIG. 5 is a plan view of the upper case.
As shown in FIG. 5, the upper case 12 is formed with screw insertion holes 12 c for screwing to the lower case 11 at substantially the center of the left and right ends and the rear end of the front end. Further, the upper case 12 is formed with screw insertion holes 12d through which screws for fixing the exhaust cover 14 to the upper case 12 are inserted at the left and right ends at the approximate center in the front-rear direction. Further, bosses 12e and 12e for screwing the exhaust cover 14 are formed on the rear surface of the upper case 12 so as to protrude rearward.

  Further, the upper case 12 has a substantially rectangular exhaust communication hole 12f formed on the left side of the rear part, and a substantially rectangular exhaust communication hole 12g formed on the right side of the rear part. The upper case 12 is formed with a restriction plate 12h that restricts the connection plug 17c from being pulled into the cleaner body 2. The restriction plate 12h is formed with a hole 12h1 from which the power cord 17b is drawn.

  The upper case 12 is made of a carbon resin containing carbon fibers, and is lighter and has higher rigidity than an ABS resin that is a non-carbon resin. The upper case 12 is formed of, for example, a thermoplastic resin (for example, PP resin or ABS resin) containing carbon fibers made of short fibers. Specifically, weight reduction can be achieved by applying PP resin rather than ABS resin.

FIG. 6 is a perspective view showing a state where the exhaust cover is removed from the cleaner body. In FIG. 6, illustration of the power cord 17b of the cord reel 16 is omitted.
As shown in FIG. 6, when the exhaust cover 14 is removed from the cleaner body 2, the exhaust communication holes 12f and 12g are exposed. The exhaust communication holes 12f and 12g allow the air discharged from the case 16 (see FIGS. 2 and 8) containing the electric blower 15 to pass through the upper case 12 from the electric blower 15 side to the exhaust cover 14 side. It is configured as a passage that passes through.

  In the vacuum cleaner 1 configured as described above, the lower case 11 made of PP resin (not including carbon fiber) including the electric blower 15 and the dust collecting portion 19, and the lower case 11 cover the upper side of the electric blower 15. The upper case 12 made of carbon resin to be attached, and the cover made of ABS resin (not containing carbon fiber) (the dust case cover 13 and the exhaust cover 14) that conceal the upper case 12 when the vacuum cleaner is used (see FIG. 1). . According to this, the lighter and high-rigidity vacuum cleaner main body 2 can be configured by applying the upper case 12 made of carbon resin instead of the entire case (casing) made of ABS resin or the like. Moreover, in the vacuum cleaner 1, the upper case 12 is concealed by the upper case 12 made of carbon resin, so that the upper case 12 cannot be visually recognized from the outside. Further, in the vacuum cleaner 1, a vacuum cleaner having a high design property (high quality in appearance) by performing, for example, sheet insert molding using the dust case cover 13 made of ABS and the exhaust cover 14 made of ABS. 1 can be realized.

  In the vacuum cleaner 1, the cover that covers the upper case 12 is composed of two parts: a dust case cover 13 that opens and closes the dust collecting portion 18, and an exhaust cover 14 that includes an exhaust port 14 d. When opening and closing the dust part 18, it is possible to prevent the dust case cover 13 from opening outward from the cleaner body 2, and the dust case cover 13 can be opened and closed in a compact manner.

  Moreover, in the vacuum cleaner 1, since the exhaust communication holes 12f and 12g of the upper case 12 are concealed by the exhaust cover 14 (because it cannot be seen from the outside), the degree of freedom of the exhaust communication holes 12f and 12g is increased. This makes it easier to adjust the direction of exhaust and the amount of exhaust.

7 is a rear view of the cleaner body shown in FIG.
As shown in FIG. 7, a substantially semicircular opening 12 m is formed on the back surface of the upper case 12. In the opening 12m, elongated plate-like wall portions 12m1, 12m2, and 12m2 extending in the vertical direction are formed. Exhaust communication holes 12n1, 12n1, 12n2, and 12n2 are formed on the left and right sides of the wall portions 12m1, 12m2, and 12m2, respectively, for communicating the inside and outside of the upper case 12. The exhaust communication holes 12n1 and 12n2 are configured as passages through which the air discharged from the electric blower 15 (see FIGS. 2 and 8) passes from the electric blower 15 side to the exhaust cover 14 side through the upper case 12. Yes.

FIG. 8 is a longitudinal sectional view of the cleaner body.
As shown in FIG. 8, the electric blower 15 includes a fan motor portion 15d in which a fan 15a and an electric motor 15b are housed in a metal housing 15c, and a case 16 in which the fan motor portion 15d is housed. Yes.

  In addition, the electric blower 15 is placed horizontally so that the fan 15a faces forward, and an intake port 15e for sucking exhaust gas from the dust collecting unit 19 is formed on the front surface. The fan motor portion 15d is accommodated in a case 16 made of synthetic resin via a vibration isolating rubber 15f. The case 16 is screwed into the lower case 11.

FIG. 9 is a perspective view of the case 16, and the shaded portion shows a portion 16a in which the vibration isolating rubber 15g is stored. The case 16 includes a substantially cylindrical cylindrical portion 16e and an exhaust portion 16d. The bottom surface portion 16f of the cylindrical portion 16e includes a flat portion 16f1, a convex portion 16b that protrudes more inside the case 16 than the flat portion 16f1, and a portion 16a surrounded by 16b.
The location 16a is a substantially rectangular opening. The convex part 16b is a substantially rectangular ring, but has a notch 16c in part. In the present embodiment, the notch 16c has two portions on a substantially rectangular diagonal. In other words, the convex portion 16b has two portions, each of which forms one rectangular side and one long side portion, and a notch 16c is provided between the two portions.
FIG. 10A is a cross-sectional view taken along line AA in FIG. As shown in FIG. 8, the electric blower 15 is accommodated in the case 16 via a vibration isolating rubber 15g. As shown in FIG. 10A, the anti-vibration rubber 15g is disposed so as to be surrounded by the substantially annular convex portion 16b of the case 16 so as to suppress movement in the rotational direction on the inner side surface of the convex portion 16b. . Further, by receiving the anti-vibration rubber 15g on the top surface on the front side of the convex portion 16b, the movement in the front-rear direction is also suppressed. If this convex portion 16b is replaced with a rib, it is necessary to reinforce and thicken the rib to withstand a drop impact, resulting in an increase in mass, sink marks and short shots. A convex shape is preferred. In addition, there is a possibility that problems such as an increase in mass, sink marks and short shots can be solved by using a plurality of ribs.

The convex portion 16b is formed in a substantially annular shape so as to surround the periphery of the vibration-proof rubber 15g, but has a structure in which a corner portion of a substantially rectangular shape is partially cut away by the notch 16c. By this notch 16c, the contact area between the vibration isolating rubber 15g and the convex portion 16b of the case 16 can be reduced, and the propagation of vibration from the electric blower 15 to the case 16 can be reduced. FIG. 10B is a cross-sectional view taken along the line EE of FIG. 10A, and shows a structure in which the convex portion 16b and the vibration isolating rubber 15g are in contact with each other. On the other hand, FIG. 10C is a cross-sectional view taken along the line D-D in FIG. 10A. Since the cross section is cut across the notch 16c, there is no convex portion 16b and no contact with the vibration isolating rubber 15g. Moreover, since the volume of the notch 16c can be reduced rather than surrounding the entire circumference, the weight can be reduced.
Further, one of the cutouts 16c (the cutout 16c located in the lower left in FIG. 9) faces the exhaust part 16d. Thus, by providing at least one portion of the notch 16c in the direction of the exhaust part 16d, the main body loss is reduced, and the exhaust can be smoothly performed to the filter 24 provided in the exhaust part 16d.

  Further, the case 16 has a substantially cylindrical shape inside the notch 16 c and the case 16, so that the volume is expanded and the exhaust path to the exhaust part 16 d and the filter 24 is expanded so as to approach the shape of the filter 24. As a result, it is possible to prevent the stagnation of the exhaust in the case 16 and to reduce the loss and to improve the suction work rate.

  The vacuum cleaner body 2 is formed with a handle 21c having a concave shape in cross section for lifting and transporting the vacuum cleaner body 2 by placing a finger on the lower surface of the front end of the lower case 11 (below the hose connection port 21b). ing.

  In the upper part of the cleaner body 2, a space Q <b> 1 is formed between the upper case 12 and the dust case cover 13, and a space Q <b> 2 is formed between the upper case 12 and the upper surface 14 s of the exhaust cover 14. Further, a space Q <b> 3 is formed between the upper case 12 and the back surface 14 t of the exhaust cover 14 at the back of the cleaner body 2.

  Further, on the upper part of the case 16, a control board 18 composed of a board 18b provided with various electrical components 18a is attached by screws and claws. An electrical component 18a is provided on the upper surface of the substrate 18b. A space Q4 through which air flows is formed between the control board 18 and the upper case 12.

  The cord reel 17 includes a reel portion 17a that winds or feeds the cord 17b, and a power cord 17b that is connected to a commercial power source. The reel portion 17a is rotatably supported in the lower case 11 so that the rotation shaft 17g is arranged facing the front-rear direction.

11 is a cross-sectional view taken along line BB in FIG.
As shown in FIG. 11, the electric blower 15 has an exhaust part 16 d formed on the right side surface (the left side in the drawing) of the case 16. An air cleaning filter 24 is attached to the exhaust part 16d. Examples of the filter 24 include a HEPA filter (High Efficiency Particulate Air Filter) and a ULPA filter (Ultra Low Penetration Air Filter).

  Moreover, as shown by the white arrow in FIG. 11, the exhaust gas discharged from the exhaust part 16d flows upward (see arrow R1), and after flowing from the right direction to the left direction of the control board 18 (arrow) R2), it is configured to flow backward (see arrow R3) through the communication hole S1 indicated by hatching. In addition, behind the electric blower 15, the edge of the disc 17 a 1 of the reel portion 17 a and the edge of the partition plate 12 i extending downward from the back surface (lower surface) of the upper case 12 abut on the wall surface. Is configured. As a result, the exhaust discharged from the exhaust portion 16 d does not flow directly toward the cord reel 17.

12 is a cross-sectional view taken along the line CC of FIG. In FIG. 12, the cord portion of the power cord 17b is not shown, and only the connection plug 17c is shown.
As shown in FIG. 12, the exhaust gas (see arrow R4) that has passed through the communication hole S1 (see FIG. 11) flows toward the exhaust communication holes 12f and 12g and cools the cord reel 17 (see FIG. 8). While flowing. Exhaust gas that has passed through the exhaust communication hole 12f flows between the upper case 12 and the exhaust cover 14, and is discharged from the hole on the left side of the exhaust port 14d (see arrow R5). Further, the exhaust gas that has passed through the exhaust communication hole 12g flows between the upper case 12 and the exhaust cover 14, and is discharged from the hole on the right side of the exhaust port 14d (see arrow R6). The exhaust gas that has not passed through the exhaust communication holes 12f and 12g is discharged to the outside through a gap between the plug lead hole 14c through which the power cord 17b is inserted and the power cord 17b (see arrow R7).

FIG. 13 is a cross-sectional view of the wheel.
As shown in FIG. 13, the wheel 20a is formed of the same material as the upper case 12 (for example, PP resin containing carbon fibers made of short fibers), and is configured to be lightweight and exhibit high rigidity. ing. Further, the wheel 20a is formed with a shaft portion 20d that is rotatably supported by the lower case 11 in the center in the radial direction of the disc-shaped wheel body 20c. Moreover, the recessed part 20e to which the sheet | seat 20f is affixed is formed in the substantially whole outer surface of the wheel main body 20c. Thus, by providing the seat 20f on almost the entire surface visible from the outside of the wheel 20a by the seat 20f, it is possible to cover the carbon fiber pattern and the like floating on the wheel main body 20c, and to provide high design electric cleaning. Machine can be realized.

  In the vacuum cleaner 1 configured as described above, the electric blower 15 and the cord reel 17 are arranged at the front and rear in the cleaner main body 2 (see FIG. 8), and the exhaust part 16 d is provided on the side surface of the electric blower 15. Thus, the left and right widths of the main body can be reduced while mounting the air cleaning filter.

  Moreover, in the vacuum cleaner 1, the height of the electric blower 15 can be made low by providing the exhaust part 16d in the side surface of the electric blower 15, and the height of the cleaner main body 2 can be made low. According to this, since a flow path in which most of the air discharged from the electric blower 15 crosses the control board 18 is formed, even if the control board 18 is arranged on the upper part of the electric blower 15, the height of the cleaner body 2 is high. Can be prevented from becoming too large.

  In the vacuum cleaner 1, the control board 18 is disposed above the electric blower 15, and in the space between the upper case 12 and the exhaust cover 14 on the opposite side of the exhaust part 16 d with the electric blower 15 interposed therebetween. A communication hole S1 for allowing the exhaust to flow is formed. According to this, the control board 18 can be efficiently cooled.

  Moreover, in the vacuum cleaner 1, since the circumference | surroundings of the electric blower 15 are covered with the triple wall by the case 16, the upper case 12, and the exhaust cover 14, there exists an effect which can reduce noise (exhaust sound etc.). .

  Furthermore, since the upper case 12 is covered with the dust case cover 13 and the exhaust cover 14, no impact from the outside is directly applied to the upper case 12, so that the upper case 12 can be made thin. The weight can be reduced.

  Next, the separate handle 30 will be described with reference to FIGS. 14 to 17. 14 is a front view showing the separate handle, FIG. 15 is an exploded perspective view showing the separate handle, FIG. 16 is a rear view when the handle cover is viewed from the back side, and FIG. FIG. 5B is a cross-sectional view taken along the line F-F, FIG. 5B is a cross-sectional view taken along the line G-G in FIG. It should be noted that the separate handle 30 can be appropriately selected to be used by a user (see FIG. 1) or not.

  As shown in FIG. 14, the separate handle 30 includes a substantially cylindrical hose insertion portion 31 through which a joint (not shown) of the hose 3 (see FIG. 1) is inserted, and a grip 32 that is a portion that is gripped by the user. , And a pair of arm portions 33 that join the hose insertion portion 31 and the grip 32 to each other.

Further, the grip 32 is inclined so that the rounded portion 32a is obliquely upward.

  The arm portion 33 is arranged in a reverse C shape in a front view, and is joined at the position of the straight portion 32b. Accordingly, a hand can be inserted into a space surrounded by the grip 32, the arm portions 33, 33, and the hose insertion portion 31, and the rounded portion 32 a of the grip 32 can be gripped by the hand.

  As shown in FIG. 15, the grip 32 includes a main body portion 34 that is formed integrally with the hose insertion portion 31 and the arm portion 33, and a grip cover 35 that covers the entire outer surface side of the main body portion 34. ing.

  The main body portion 34 has an inner surface portion 34s that constitutes the inner surface of the rounded portion 32a and an inner surface portion 34t that constitutes the inner surface of the linear portion 32b.

  The grip cover 35 has an outer surface portion 35s constituting the outer surface of the rounded portion 32a and an outer surface portion 35t constituting the outer surface of the linear portion 32b.

  In this way, by configuring the grip 32 with the two parts of the main body portion 34 and the grip cover 35, the grip 32 can be formed into a rounded and thick shape, so that the ease of holding for the user is improved. Moreover, the vacuum cleaner main body 2 can be reduced in weight by using it without attaching the separate handle 30.

  As shown in FIG. 16, a claw portion 35a that protrudes substantially rearward is formed at the lower edge of the round portion 35s. The claw at the tip of the claw portion 35a is downward. In addition, protrusions 35f protruding in an L shape are formed at a plurality of locations on the upper inner surface of the round portion 35s.

  The straight portion 35t is formed with a claw portion 35b protruding inward at the lower end edge portion at a position corresponding to the arm portion 33. The claw at the tip of the claw portion 35b faces downward. Further, claw portions 35c and 35d are formed vertically on the inner surface of the end portion of the straight portion 35t. A boss 35e into which a screw 36 (see FIG. 14) is screwed is formed at the end of the straight portion 35t.

  Returning to FIG. 15, an insertion hole 34 a into which the claw portion 35 a is inserted is formed in the inner surface portion 34 s. Insertion holes 34b, 34c, 34d into which the claw portions 35b, 35c, 35d are inserted are formed in the inner surface portion 34t. Further, a screw insertion hole 34e is formed in the inner surface portion 34t at a position corresponding to the boss 35e.

  As shown in FIG. 17A, the claw portion 35a of the grip cover 35 is locked to a locking portion 34a1 formed in the insertion hole 34a, and the upper edge 34s1 of the inner surface portion 34s of the main body portion 34. Is sandwiched between the upper edge 35s1 of the outer surface 35s of the grip cover 35 and the projection 35f.

  As shown in FIG. 17B, the claw portion 35c of the grip cover 35 is locked by being inserted into the insertion hole 34c from the front to the rear.

  As shown in FIG. 17C, the claw portion 35d of the grip cover 35 is locked by being inserted into the insertion hole 34d from the front to the rear. Further, the claw portion 35b of the grip cover 35 is inserted into the insertion hole 34b and locked to the surface of the inner surface portion 34t.
