That is, the height position of the suction port 50 is located in the imaginary tangent plane P that is tangent to the lower ends of the front wheels 43 and the rear wheels 44. An imaginary plane (plane) that is at least a predetermined distance small, for example, above about 1 mm to 2 mm, and tangent to the edge that divides the suction port 50, is substantially parallel to the tangent plane P. The height position of the suction port 50 is further below the lower end portion of the tap 45 in the retracted state and the front partition wall 56. As shown in FIGS. 6 and 7, both end portions (left and right side portions) in the longitudinal direction of the suction port 50 are located near the front wheel 43, respectively.

The beater mounting portion 51 is formed in a groove shape having a long side in the left-right direction throughout the front-rear area including the substantially central portion of the case 41 in the front-rear direction. The width of the beater mounting portion 51 in the front-rear direction is set larger than the suction port 50 and the sealing member mounting portion 53.

The holding portion 52 shown in FIGS. 1 (a) and 2 to 4 is a person who presses the quilt B (futon fabric F) in front of the suction port 50, and is provided on the rear wheel 44, the suction port 50, and the rear of the housing 41. The side partition wall 55 is further forward, and is provided at a position approximately equal to the axis 43 a of the front wheel 43 in the front-rear direction, for example. The holding portion 52 is located further behind the sealing member 46 (and the sealing member mounting portion 53) and the front partition wall 56, and is provided to protrude downward from the housing 41. In other words, the holding portion 52 is located between the suction port 50 and the sealing member 46 in the front-rear direction. The holding portion 52 is located inside the beater mounting portion 51. The holding portion 52 is formed in a rib shape having a long side shape in the left-right direction. In the present embodiment, a plurality of holding portions 52 are provided spaced apart from each other in the left-right direction, but may be a single. Further, as shown in FIG. 3 and FIG. 4, the holding portion 52 is inserted into the opening portion 69 of the beater 45 and serves as a guide for the up and down movement of the beater 45. In addition, as shown schematically in FIG. 5, the lower end portion of the holding portion 52 is located further above the lower end portion of the front wheel 43 and the lower end portion of the seal member 46, the lower end portion of the front partition wall 56, and the height positions of the suction port 50 are further lower. More specifically, the lower end portion of the holding portion 52 is located further inside the outer contour of the front wheel 43 (the imaginary cylindrical surface (outer peripheral surface 61) including the surfaces of the convex portion 63 and the protruding portion 64), and is located on the front wheel 43. The imaginary cylindrical surface on the surface of the recess 62 is further outside.

The seal member mounting portion 53 shown in FIGS. 6 and 7 is formed in the shape of a long groove in the left-right direction in front of the tap 45 (and the tap mounting portion 51) and the front partition wall 56. That is, the sealing member mounting portion 53 is located forward of the tap 45 (and the tap mounting portion 51) on the side opposite to the suction port 50. When the sealing member 46 is not provided, the sealing member mounting portion 53 is unnecessary.

The rear partition wall 55 divides the suction port 50 and the flapper mounting portion 51 back and forth, and is formed into a continuous rib shape along the longitudinal direction of the housing 41, that is, the left-right direction. The rear partition wall 55 is provided in the up-down direction in front of the suction port 50 and behind the tap 45 and the sealing member 46. Further, as shown in FIG. 5, the lower end portion of the rear partition wall 55 is located above the lower end portion of the front wheel 43, the lower end portion of the rear wheel 44, and the lower end portion of the holding portion 52, and the lower end portion of the front partition wall 56 is further below. . Furthermore, when viewed from the side, the rear partition wall 55 is located further inside the outer contour of the front wheel 43 and further outside the virtual cylindrical surface of the front wheel 43 including the surface of the recessed portion 62.

The front partition wall 56 shown in FIG. 6 and FIG. 7 divides the beater mounting portion 51 and the sealing member mounting portion 53 back and forth, and deforms the housing 41 (bedding brush 14) to move forward, that is, it deforms relatively backward. The front end side of the sealing member 46 is supported (FIG. 1 (a)). The front partition wall 56 is formed in a continuous rib shape along the longitudinal direction of the housing 41, that is, the left-right direction. The front partition wall 56 is schematically shown in FIG. 5, in front of the axis 43 a of the rear wheel 44, the rear partition wall 55, the suction port 50, the holding portion 52, the tapper 45, and the front wheel 43 and behind the seal member 46. , Set up and down. Furthermore, when viewed from the side, the front partition wall 56 is located further inside the outer contour of the front wheel 43 and the virtual cylindrical surface including the surface of the recessed portion 62 of the front wheel 43 is further outside. In addition, the front side of the lower end portion of the front partition wall 56 facing the front end side of the sealing member 46 is an inclined surface 56 a which is a support surface which is inclined downward toward the rear.

Next, the operation of the embodiment will be described with reference to FIGS. 1 (a) and 1 (b) to 8.

At the time of cleaning, the rotary tube 42 connected to the bedding brush 14 is inserted into the cleaner body 12 (the connection portion 32 (the body connection port 38)) and is detachably locked by a clamp 39. In this state, the quilt brush 14 communicates with the suction side of the electric blower 25 (via the main body connection port 38 and the dust collecting device 22).

Further, in the electric cleaner 11, the user who holds the holding portion 31 places the quilt brush 14 on the quilt fabric F of the quilt B, and operates the setting button 36 provided on the holding portion 31, thereby The control part 27 drives the electric blower 25 in accordance with the set action, and drives the driving part to move the flapper 45 up and down, so that the bedding brush 14 alternately walks in the front-rear direction on the surface to be cleaned. The flapper 45 moves up and down to pick up dust entering the inside of the quilt B (FIGS. 3 and 4), and uses the negative pressure generated by the driving of the electric blower 25 to suck the dust together with the air from the suction port 50.

When the bedding brush 14 is advanced, the user presses from behind, and the front wheel 43 having the axis 43a in front of the rotating tube 42 directly applied by the press grasps the bedding B (the bedding fabric) by the concave portion 62 and the convex portion 63. F). In addition, the sealing member 46 is bent rearward relatively by the friction with the quilt B (the quilt fabric F). At this time, the lower end portion of the sealing member 46 protrudes further below the lower end portion of the front partition wall 56 and thereby bends so as to be in close contact with the inclined surface 56 a of the lower end portion of the front partition wall 56. The lower end portion is supported by the front side partition wall 56 and enters between the lower end portion of the front side partition wall 56 and the quilt B (futon fabric F) (FIG. 1 (a)). As a result, the sealing member 46 functions as a so-called pry (rod), and the quilt brush 14 runs smoothly forward. Moreover, when the structure which does not provide the sealing member 46 (seal member mounting part 53) is used, the front side partition wall 56 functions as a skid instead of the sealing member 46, and by this, the quilt brush 14 travels forward.

On the other hand, when the quilt brush 14 is advanced backward, the user pulls the quilt brush 14 backward, whereby the rear wheel 44 having the axis 44 a further behind the rotating tube 42 to which the load is directly applied, grasps the quilt together with the front wheel 43. B (futon fabric F). At this time, the rotating tube 42 connected to the cleaner body 12 held by the user holding the gripping portion 31 is slightly downward relative to the housing 41 compared to the time when the rotary tube 42 is moved forward. In the rotating (falling) state, due to the rotation of the rotating tube 42 and the friction with the quilt B (the quilt fabric F), the front side of the casing 41 is intended to float relatively upward, but the axis 42a of the rotating tube 42 It is located between the axis 43a of the front wheel 43 and the axis 44a of the rear wheel 44 in the front-rear direction and further below the axis 44a of the rear wheel 44 in the up-down direction, so that the operation load applied to the rotating tube 42 does not slide up and is applied to the whole The rear wheel 44 is biased by the urging member 59, and the front side of the housing 41 is relatively rotated downward with respect to the rotating tube 42, thereby preventing the quilt B from floating from the front side of the housing 41, and the quilt brush 14 Walk toward the back with a stable gesture (dashed lines in Figure 2). In addition, the lower end portion of the sealing member 46 is curved toward the front relatively by friction with the quilt B (the quilt fabric F), thereby maintaining contact with the quilt F of the quilt B (FIG. 2). Therefore, the front side of the suction port 50 and the tap 45 is sealed by the sealing member 46 to prevent the dust picked up by the tap 45 from leaking forward or a decrease in the degree of vacuum around the suction port 50 caused by air leakage.

In addition, the quilt brush 14 presses the quilt B (the quilt fabric F) in front of the suction port 50 by the front wheels 43 on both sides, the holding portion 52, and the tap 45 in the protruding state when the quilt brush 14 moves forward and backward. The quilt B (quilt fabric F) is pressed behind the suction port 50 by the rear wheel 44, and thereby, the quilt B (quilt fabric F) is pressed downward along the suction port 50 before and after the suction port 50, so that The degree of vacuum around the suction port 50 is increased. In this state, the negative pressure acts on the suction port 50 located slightly above the lower end of each of the front wheel 43, the holding portion 52, the tapper 45, and the rear wheel 44 in the protruding state. In the narrow range of the position corresponding to the narrow suction opening 50 in the front-back direction, the quilt fabric F is adsorbed and lifted slightly upward with respect to the inner cotton I, so that the quilt fabric F moves away from the inner cotton I upwards, thereby generating a gap G. (Figure 1 (b)). Therefore, the negative pressure generated from the suction port 50 by passing through the bedding material F causes the gap G to generate the suction wind flowing to the center of the suction port 50 in the left-right direction along the longitudinal direction of the suction port 50. Fine dust entering the inner cotton I, such as pulverized mite debris or feces, or fine dust that may cause allergic symptoms such as pollen, is inhaled together with the dust adhered to the surface of the quilt fabric F through the permeable quilt fabric F.

The dust-laden air sucked from the suction port 50 is sent to the dust collecting device 22 through the communication hole portion 58 and the rotating tube 42 and through the main body connection port 38, and is separated from the air and captured. The dust-separated air is sucked into the electric blower 25 to cool the electric blower 25, and is then discharged to the outside of the cleaner body 12 from an exhaust port (not shown).

According to one embodiment described above, a long-side suction port 50 is provided in front and rear of the lower portion of the casing 41 in a direction crossing the walking direction, that is, in the left-right direction, and is arranged and held along the long-side direction of the suction port 50. With the portion 52 and the rear wheel 44, the quilt B (the quilt fabric F) can be pressed by the holding portion 52 and the rear wheel 44 at positions in front of and behind the suction port 50, that is, positions where the suction port 50 is sandwiched back and forth. ). Therefore, the negative pressure acting on the suction port 50 located in the space where the quilt B (the quilt fabric F) is pressed forward and backward by the holding portions 52 and the rear wheels 44 is set in front of the suction port 50 and the suction port 50 includes the suction port 50. Positions behind both ends in the longitudinal direction work without leaking, whereby the quilt fabric F of the quilt B can be lifted relative to the inner cotton I, and the back of the quilt fabric F can be sucked in. The wind flows into the gap G between the quilt fabric F and the inner cotton I, so that dust entering the back surface of the quilt fabric F, that is, the inner cotton I can be effectively cleaned.

Especially in the case of the quilt B, not only dust adheres to the quilt fabric F, but also a structure in which fine dust easily penetrates the quilt fabric F and enters the inner cotton I. On the other hand, the inner cotton is taken out from the quilt fabric F It is tedious and not easy to clean. Therefore, with the quilt brush 14 of this embodiment, it is not necessary to take out the inner cotton I from the quilt fabric F, and the dust passing through the quilt fabric F and entering the inner cotton I can be cleaned, thereby enabling a good operation. Sex to ensure bedding B hygiene.

In addition, since the quilt B (the quilt fabric F) is pressed in the longitudinal direction by the rib-shaped holding portion 52 in front of the suction port 50, the front of the suction port 50 can be more reliably closed, and the load The pressure works more effectively, and the dust is sucked in efficiently.

Furthermore, since the rear wheels 44 are arranged so that they are partially behind the both ends of the suction port 50 in the longitudinal direction, the bedding of the bedding B located behind the both ends of the suction port 50 can be reliably pressed by the rear wheels 44. Fabric F. Therefore, the leakage of the negative pressure (suction wind) at the rear position of the both ends of the suction port 50 can be suppressed more reliably, and the quilt fabric F can be lifted more reliably over the substantially entire longitudinal direction of the suction port 50.

In addition, since the front wheels 43 are disposed to face the both ends in the longitudinal direction of the suction port 50, the running performance of the quilt brush 14 can be further improved, and the front wheels can also be used at positions on both sides of the suction port 50. 43 to press the quilt fabric F of the quilt B. Therefore, the quilt fabric F of the quilt B can be lifted more reliably than the inner cotton I by the negative pressure acting on the suction port 50.

Further, the casing 41 is provided with a tap 45 separately from the holding portion 52 in front of the suction port 50, and thereby the quilt is pressed in front of and behind the suction port 50 by the holding portion 52 and the rear wheel 44. In the space of B (the quilt fabric F), the dust entering the quilt B can be scraped out by the tap 45, so that the scraped dust can be effectively sucked in through the suction port 50, and a sealing member is provided in front of the holding portion 52. 46 is closed, so that the vacuum degree of the suction port 50 can be increased, and dust can be sucked in from the suction port 50 more efficiently.

In addition, since the long side dimension of the tap 45 is substantially equal to the long side dimension of the suction port 50, the tap 45 can be used in front of the suction port 50 at substantially the entire position in the longitudinal direction of the suction port 50. The quilt B (quilt fabric F) imparts vibration. Therefore, it is possible to use the entire long suction inlet 50 without waste to suck in dust more efficiently.

In addition, by using the quilt brush 14, it is possible to provide an electric cleaner 11 capable of effectively cleaning dust entering the back side of the quilt fabric F of the quilt B.

In addition, in the above-mentioned embodiment, the rear wheels 44 may not be a pair, but one long side rear wheel may be provided, and three or more rear wheels may be provided. As the rear pressing portion, a rib or the like formed along the longitudinal direction of the suction port 50 may be used instead of the rear wheel 44.

Further, as the front pressing portion, even if the holding portion 52 is not provided, for example, a pad 45 that adopts a structure that vibrates the quilt B in the left-right direction, for example, may be used as the front pressing portion. The same effect as the embodiment, and the slap device 45 also serves as the front pressing portion, which can further simplify the structure.

Furthermore, in addition to the quilt B, the quilt brush 14 can also clean a seat cushion etc. similarly, for example.

As the power source of the electric sweeper 11, in addition to the battery 28, an external power source such as a commercial AC power source may be used.

In addition, the bedding brush 14 is connected to the sweeper body 12 provided separately from the bedding brush 14 via the rotating tube 42 to constitute the electric sweeper 11. However, an electric blower 25 may be installed in the casing 41, and The grip portion 31 is provided in the housing 41 to constitute the electric cleaner 11.
