It is characterized by having a protruding wall portion for draining drainage that surrounds at least the upper side and both sides of the drainage hole on the rear surface side of the rear wall portion.

  When an object in which dust and liquid such as water are mixed is collected in the collecting unit, it is desirable to separate and remove the liquid from the collected object before discarding the dust in a garbage container or the like. For this purpose, the rear wall portion is gradually inclined rearward so that only the liquid is discharged from the drainage hole as much as possible.

  The liquid discharged from the collecting portion side, which is the front surface side of the rear wall portion, through the drain hole is discharged to the back surface side of the rear wall portion. Since at least the upper side and both sides of the drainage hole on the back side of the rear wall part are surrounded by the protruding wall part for draining the drainage liquid, the liquid discharged to the back side of the rear wall part is for draining. The liquid is drained by the protruding wall portion and is detached downward. As a result, the liquid discharged from the drainage hole to the back side of the rear wall portion may be scattered to the side or transmitted to the handle, and the handle or the user's hand holding the handle may become dirty with the drainage. It is prevented.

  The dust collector of the present invention has a movement-inhibiting convex portion for inhibiting movement of dust collected in the collecting portion toward the drainage hole and / or below the drainage hole in the surface portion of the rear wall portion. It is desirable to have a recess.

  In this case, when the rear wall portion is gradually inclined rearward, the movement of the dust in the collection is hindered by the movement-inhibiting convex portion and / or the concave portion, so that the dust is drained. It is effective in discharging the liquid mixed in the object from the drainage hole while avoiding as much as possible the discharge from the hole and closing the drainage hole.

Further, in the dust collector of the present invention, the side wall portions on both sides of the rear wall portion extend rearward from the rear wall portion to constitute the extended side wall portions, respectively, and the bottom portion is formed between the two extended side wall portions, so that the rear wall portion is formed. A liquid reservoir recess is provided behind the
The liquid reservoir recess has a drain hole that opens to the back side,
On the back surface side, it is preferable that at least the rear and both sides of the liquid drainage hole are surrounded by the liquid draining protruding wall.

  In this case, when the rear wall portion is gradually tilted rearward, when some liquid does not completely flow out of the drainage hole and climbs over the upper end portion of the rear wall portion, the liquid is separated from the side walls for both inclined walls. And the two extended side wall portions are guided to the liquid reservoir recess at the rear of the rear wall portion and discharged from the drain hole of the liquid reservoir recess to the back surface side. Therefore, it is possible to prevent the liquid over the rear wall from overflowing. The liquid discharged from the drain hole to the back side is drained by the projecting wall for draining and is released downward, so that it is scattered to the side and the user's hand holding the handle or handle. Is prevented from being contaminated by drainage.

  According to the dust collector of the present invention, when the liquid mixed in the collected material is discharged from the drainage hole, the liquid discharged from the drainage hole to the back side of the rear wall portion is a protruding wall for draining. The liquid is drained by the portion and separated downward, so that it is prevented that the gripper or the user's hand gripping the handle by being scattered to the side or contaminated by the drainage is contaminated by the drainage.

  Embodiments of the present invention will be described with reference to the drawings.

  The drawings are all about dust removal as an example of the embodiment of the present invention. FIG. 1 is a perspective view, FIG. 2 is a plan view, FIG. 3 is a bottom view, and FIG. FIG. 5 is an enlarged perspective view of the main part on the back side.

  The dust collector has a handle portion H on the rear side of the collecting portion C.

  The collecting part C includes a bottom plate part B from which dust is swept from the front edge part B1, a side wall part S rising from both sides of the bottom plate part B, and a rear wall part rising from the rear side of the bottom plate part B. R is included.

  The both side wall portions S of the collecting unit C gradually decrease in distance from each other toward the rear. However, the present invention is not limited to this, and may be parallel to each other, for example.

  At the front part of the bottom plate part B, a curved convex part B2 is provided to prevent dusts swept into the collecting part C from spilling out from the front edge part B1 during use.

  The rear wall portion R is inclined with respect to the bottom plate portion B so as to rise rearward in a state where the bottom plate portion B is placed on a horizontal plane. The angle of ascending slope can be set to 85 degrees or less, for example. It can also be 80 degrees or less, 75 degrees or less, or 70 degrees or less, and can be 30 degrees or more, 45 degrees or more, or 60 degrees or more. The inclination angle of the rear wall portion is a constant angle in this example, but the inclination may be changed in a curved shape stepwise or continuously. However, the rear wall portion is not necessarily inclined so as to rise rearward, and may be erect, for example.

  The rear wall portion R has a plurality of drain holes D for discharging liquid on the back side of the rear wall portion R in the upper half thereof. The drainage hole D is formed into a plurality of horizontally long slits penetrating downwardly through the rear wall R in a posture in which the liquid collected in the collection unit C is discharged through the drainage hole D by tilting the collection unit C backward. The upper and lower sides are provided in parallel. The drainage hole can be provided in the rear wall, preferably above the lower third, and can also be above the lower third. The shape of the drainage hole can be, for example, a vertically long slit shape, an oblique or bent slit shape, a small hole, or the like.

  On the rear surface side of the rear wall portion R, there is a protruding wall portion W for draining drainage that surrounds the upper side and both sides of the drainage hole D like a gate. The projecting wall for draining is not limited to a gate shape surrounding at least the upper side and both sides of the drainage hole, and the upper and both sides, or the upper, both sides, and the lower side are substantially U-shaped, for example. , Substantially V-shaped, arc-shaped, rectangular, circular, or elliptical.

  The portion on the rear side of the protruding wall portion W for draining the liquid accommodated in the collecting portion C by inclining the collecting portion C rearward from the ridge line portion W1 (the portion along the top portion) of the protruding wall portion W. It is formed so as not to protrude downward in the posture when discharging through the drainage hole D. For example, a rib or a surface that protrudes in the same manner as the protruding wall portion W and is connected to the protruding wall portion W and continues to the rear side is not provided. In the case of this example, the protruding structure is formed so as not to be continuous on the rear side of the protruding wall portion W for draining liquid. Thereby, the liquid discharged to the back surface side of the rear wall portion R through the drainage hole D is prevented from being transmitted rearward from the ridge line portion W1 of the protruding wall portion W.

  Liquid guide protrusions W2 are provided at both ends of the rear portion of the protruding wall W for draining liquid. The liquid guide protrusion W2 is for allowing the liquid discharged to the back side of the rear wall portion R through the liquid discharge hole D to flow down and desorb along the liquid guide protrusion W2. It is formed so as to protrude substantially downward in the posture when the liquid stored in the collecting portion C is inclined and discharged through the drainage hole D.

  Below the drainage hole D on the surface portion of the rear wall R, there are a large number of movement-inhibiting horizontally elongated grooves G for inhibiting the movement of dust collected in the collection unit C toward the drainage hole D. It is provided in parallel.

  The handle portion H extends rearward and upward from the rear wall portion R. Both sides of the handle portion H are constituted by extended side wall portions T in which the side wall portions S on both sides of the rear wall portion R are extended rearward from the rear wall portion R, and the interval between the extended side wall portions T is rearwardly upward. It gradually shrinks toward. The lower edge portions of both the extended side wall portions T are connected to each other by a groove bottom plate portion U, and the front side of the handle portion H is formed in a longitudinal groove portion N having an upper opening.

  The collection part C and the handle part H are continuous in a state where the whole is opened upward, and the handle part M1 of the heel M is fitted into the vertical groove part N of the handle part H, and the front part of the collection part C By accommodating the sweeping part M2 of the kite M on the side, the kite M is detachably held.

  Arc-shaped ribs A are provided on both sides from the rear wall portion R of the collecting portion C to the back surface portion of the base portion of the handle portion H, respectively. The protruding wall portion W and the back surface side portion of the liquid reservoir recess E are formed to have a protruding height that is equal to or lower than the height of both arc-shaped ribs A.

  On both sides of the top of the rear wall R, weir plates L that are lower than the height of the side wall S are erected, and a square weir Q is formed between the two dam plates L. On the rear side of the dam plate portion L, a liquid reservoir recess E having a substantially V-shaped vertical cross section is provided, and a liquid drain hole J opened on the back surface side is provided at the bottom of the liquid reservoir recess E. The opening on the back side of the liquid drain hole J is surrounded by a protruding wall portion W for draining liquid. On the rear side of the liquid reservoir recess E, a retaining wall K that is lower than the height of the extended sidewall T is provided to prevent the liquid from flowing toward the end of the handle portion H.

  When using as a dust collector, after removing the ridge M, usually, at least the front edge B1 of the bottom plate B is in contact with the surface to be cleaned, and dust is swept from the front edge B1 to the collecting part C. Include. For example, the bottom plate B can be used in a state where it is placed on the surface to be cleaned, that is, in a state where the front edge B1 and the rear end of the bottom plate B are in contact with the surface to be cleaned.

  When liquids such as water are mixed in addition to dusts in the collected matter stored in the collecting part C, the liquid is discharged from the rear wall R by tilting the collecting part C backward. It discharges to the back side through the hole D. Below the drainage hole D on the surface portion of the rear wall R, there are a large number of movement-inhibiting horizontally elongated grooves G for inhibiting the movement of dust collected in the collection unit C toward the drainage hole D. Since it is provided in parallel, when the collecting part C is tilted backward, the dust in the collected matter is prevented from moving backward, and the dust is discharged from the drainage hole D or discharged. It is effective in discharging the liquid mixed in the object from the drainage hole D while avoiding closing the liquid hole D as much as possible.

  In addition, the rear wall portion R is inclined with respect to the bottom plate portion B so as to rise rearward in a state where the bottom plate portion B is placed on a horizontal plane. As compared with the case where the bottom plate portion B is vertical, the liquid in the object reaches the drainage hole D of the rear wall portion R when the angle of the downward descending inclination of the bottom plate portion B is shallow. Therefore, it is possible to drain the liquid mixed in the object while avoiding the dust in the collected material from moving largely backward and discharging the dust from the drain hole D or closing the drain hole D. It can be discharged from the hole D.

  The opening of the drainage hole D on the rear surface side of the rear wall R is surrounded by a gate shape on the upper and both sides by a drainage draining projection wall W. The liquid discharged to the rear surface side of the portion R is drained by the projecting wall portion W for draining, and is separated downward. In particular, it flows down along the liquid guide protrusion W2. Thereby, the liquid discharged from the drainage hole D to the back surface side of the rear wall R is scattered to the side or transmitted to the handle part H, so that the user holding the handle part H or the handle part H Prevents hands from getting dirty with drainage.

  When the rear wall portion R is tilted rearward, when a part of the liquid does not completely flow out of the drainage hole D and climbs over the upper end portion of the rear wall portion R, the liquid becomes the side wall portions S for both inclined walls. In addition, both the extended side wall portions T guide the liquid reservoir recess E behind the rear wall portion R, and discharge the liquid from the drain hole J of the liquid reservoir recess E to the back surface side. Therefore, it is possible to prevent the liquid that has passed over the rear wall R from overflowing. The liquid discharged from the drainage hole J to the back side is drained by the projecting wall W for draining the liquid and is released to the lower side of the dust. Therefore, the liquid is scattered to the side, the handle part H and the handle part H This prevents the user's hand holding the handle from being contaminated by drainage.

  Thus, after discharging the liquid from the collection part C as much as possible, the dusts accommodated in the collection part C are discarded in a trash box or the like.

  It should be noted that the dimensions, number, material, shape, relative arrangement, etc. of the component parts in the description of the above embodiments are limited to the scope of the present invention unless otherwise specified. It is not intended to be limiting, but merely an illustrative example.
