Description

  The present invention relates to a cleaning brush suitable for kitchen cleaning applications such as tableware stain removal and root vegetable mud removal, and other cleaning applications.

  As a cleaning brush used for cleaning applications, for example, a brush configured using artificial grass has been proposed (see, for example, Patent Document 1). The lawn scrubber (cleaning brush) disclosed in Patent Document 1 is configured by forming a scrubber with an artificial turf having a large number of brush pieces, and attaching the scrubbing made of the artificial turf to the base. When such a cleaning brush is used, it is less likely to be damaged when washing dishes, kitchen sinks, or the like, as compared to a general scrubbing brush composed of a hard brush.

  However, the conventional cleaning brush has a problem that it is difficult to remove dirt (especially dirt near the base of the brush piece) attached to many brush pieces. Such a problem is not preferable in terms of hygiene. For example, when it is used for a kitchen, there is a problem that it becomes unsanitary.

Japanese Utility Model Publication No. 60-83556

  The present invention has been devised under such circumstances, and it is an object to provide a cleaning brush suitable for various uses such as kitchen use, which easily removes dirt adhering to a brush piece. It is said.

  In order to solve the above problems, the present invention takes the following technical means.

  The cleaning brush provided by the present invention includes a bendable plate-like base, a plurality of through holes formed in the thickness direction of the base, and a plurality of tapered brush pieces extending from one surface of the base. And the plurality of brush pieces are constituted by a brush piece group including a plurality of brush pieces arranged around each through hole.

  In the cleaning brush according to the present invention, a large number of brush pieces are tapered. For this reason, at the time of cleaning, each brush piece has an appropriate elastic restoring force on the base end side, and can also remove dirt from a cleaning target having an uneven surface on the tip end side. .

  Moreover, all the many brush pieces are arranged around the through-hole formed in the base. For this reason, for example, at the time of cleaning the cleaning brush, it is easy for water to pass through the base (base end) of the brush piece by each through-hole, and dirt attached to the vicinity of the base end of the brush piece is easily removed. Further, during cleaning, the brush piece is also bent while the base is bent, so that the dirt attached to the surface of the base and the brush piece can be efficiently removed.

  In a preferred embodiment, a plurality of protrusions having a substantially constant height are provided on the other surface of the substrate. According to such a configuration having a plurality of protrusions, when the cleaning brush is used, the plurality of protrusions function as a slip stopper when the substrate is gripped by hand. In addition, according to the configuration having the plurality of protrusions, for example, even if a cleaning brush is placed on a sink or the like, the other surface of the base body does not adhere to the sink or the like, so that it has excellent drainability and is wet. It can also function as an anti-slip when placed where it is.

  In a preferred embodiment, the plurality of brush pieces constituting the group of brush pieces are arranged in a ring at regular intervals.

  In a preferred embodiment, the plurality of through holes are formed to have substantially the same size and are arranged substantially evenly in a plan view of the base.

  In a preferred embodiment, the base and the plurality of brush pieces are integrally formed of resin or rubber.

  Other features and advantages of the present invention will become more apparent from the detailed description given below with reference to the accompanying drawings.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

  1 to 4 show an example of a cleaning brush according to the present invention. The cleaning brush A of the present embodiment includes a plate-like base body 1, a plurality of through holes 2 formed in the thickness direction of the base body 1, a large number of brush pieces 3 extending from the upper surface 1 a of the base body 1, and the base body 1. And a plurality of protrusions 4 provided on the lower surface 1b of the.

  The substrate 1 has a substantially constant thickness and has a substantially square shape in plan view. The outer dimensions of the base 1 are, for example, about 10 cm on a side, and the thickness of the base 1 is, for example, about 1.2 mm.

  The plurality of through holes 2 are formed to have substantially the same size and are arranged substantially evenly in a plan view of the base body 1. In the present embodiment, for example, the diameter of the through holes 2 is about 2.5 mm, and the through holes 2 are arranged at a constant pitch in the vertical and horizontal directions.

  A large number of brush pieces 3 are constituted by a brush piece group 3 </ b> A composed of a plurality of brush pieces 3 arranged around each through-hole 2. In the present embodiment, each brush piece group 3A is composed of, for example, six brush pieces 3, and these six brush pieces 3 are annularly arranged at equal intervals.

  As shown in FIG. 3, the brush pieces 3 extend from the upper surface 1 a of the base body 1 at a substantially right angle, and are each tapered. More specifically, each brush piece 3 has a substantially triangular pyramid shape having a vertex 31 at the tip. The length from the proximal end to the distal end of each brush piece 3 is, for example, about 1 cm. As can be understood from FIG. 5, the cross section of the base end portion of each brush piece 3 is a substantially isosceles triangle, and the base 32 of the isosceles triangle has a group of brush pieces to which the brush piece 3 belongs. It is directed to the outside of 3A, and the apex angle 33 of the isosceles triangle is directed to the inside of the brush piece group 3A.

  Further, as shown in FIG. 5, among the plurality of brush pieces 3 constituting each brush piece group 3A, the base end portion of the adjacent brush piece 3 has an interval L2 between the adjacent bottom angles 34 and 34. Is smaller than the distance L1 between the apex angles 33, 33.

  In FIG. 7, a cross section at a predetermined height of the six brush pieces 3 constituting the brush piece group 3 </ b> A appears, and the cross section is a substantially isosceles triangle having a base 32 ′ and an apex angle 33 ′. ing. As understood from FIGS. 5 and 7, when the cross section of the brush piece 3 is taken, the bottom 32 (32 ') is in the same position regardless of the cross section. Therefore, the side surface of the brush piece 3 in which the bottom 32 (32 ') portion is continuously formed extends vertically upward from the base 1. On the other hand, the apex angle 33 (33 ') approaches the base 32 (32') from the proximal end toward the distal end. As understood from this, the center of the cross section of the brush piece 3 is biased toward the outer side of the brush piece group 3A to which the brush piece 3 belongs as it goes from the base end to the tip end.

  As shown in FIG. 3, each of the plurality of protrusions 4 has a substantially constant height. As shown in FIG. 4, in the present embodiment, the protrusion 4 is substantially circular in a bottom view. The plurality of protrusions 4 and the plurality of through holes 2 are arranged in a staggered manner.

  As shown in the upper right in FIG. 2, the base body 1 is provided with a hole 5. This hole 5 is used for storing the cleaning brush A by attaching a tag for displaying a product or a hanging string for displaying a product, or by hanging it on a hook or the like when not in use. The hole 5 is formed in place of the through hole 2 and the brush piece group 3A at a position where the one through hole 2 and the brush piece group 3A corresponding to the through hole 2 are to be formed.

  The cleaning brush A having the above configuration is integrally formed of resin or rubber, and is made of, for example, EMMA resin (ethylene-methyl methacrylate copolymer). EMMA resin has moderate flexibility and rubber-like elasticity. Thereby, the base | substrate 1 can be bent comparatively easily, and the brush piece 3 has an elastic restoring force.

  Next, the operation of the cleaning brush A having the above configuration will be described.

  The cleaning brush A of the present embodiment is used for kitchen cleaning applications such as tableware dirt removal and root vegetable mud removal. Since the base body 1 can be bent, the base body 1 can be bent in accordance with the shape of the object to be cleaned during use. Therefore, for example, when cleaning an object having a curved surface portion such as a colander or a root vegetable, the base 1 can be bent along the curved surface portion, which is convenient.

  Many brush pieces 3 are tapered. For this reason, at the time of cleaning, each brush piece 3 has an appropriate elastic restoring force on the proximal end side, and has a fine uneven surface on the distal end side (for example, monkeys and root vegetables). However, it can scrape off dirt.

  The brush pieces 3 have a substantially triangular pyramid shape having apexes 31 and are arranged at equal intervals around the through holes 2 that are evenly arranged. For this reason, even if the cleaning brush A is rubbed in any direction, the elastic restoring force of the brush piece 3 is appropriately exhibited, and the dirt on the cleaning object can be more reliably removed.

  Further, all the many brush pieces 3 are arranged around the through-hole 2 formed in the base body 1. For this reason, for example, when cleaning the cleaning brush A, the through holes 2 allow water to pass through the base (base end) of the brush piece 3, and dirt attached to the vicinity of the base end of the brush piece 3 can be easily removed. Further, during cleaning, the brush piece 3 is also bent while the base body 1 is bent, so that the dirt attached to the surface of the base body 1 and the brush piece 3 can be efficiently removed.

  As described with reference to FIGS. 5 and 7, the cross section of each brush piece 3 is a substantially isosceles triangle, and the brush piece 3 belongs to the base 32 (32 ′) of the isosceles triangle. It faces the outside of the brush piece group 3A, and the apex angle 33 (33 ′) of the isosceles triangle faces the inside of the brush piece group 3A. Further, among the plurality of brush pieces 3 constituting each brush piece group 3A, with respect to the proximal end portion of the adjacent brush piece 3, the interval between the adjacent base angles 34 and 34 is the interval between the apex angles 33 and 33. Has been smaller than. Furthermore, the center of the cross section of the brush piece 3 is biased toward the outer side of the brush piece group 3A to which the brush piece 3 belongs as it goes from the proximal end to the distal end. As a result, when water is flowed from above the cleaning brush A, the water that has entered the inside of the brush piece group 3A has an apex 31 at the tip of the brush piece 3 and a base angle 34 and apex angle 33 at the base end of the brush piece 3. As shown by the arrows in FIG. 7, they are guided by the surface formed, gather at the center C1 of the brush piece group 3A, and are discharged through the through hole 2. As can be understood from the above, at the time of cleaning, dirt attached to the brush piece 3 can be more efficiently removed.

  A plurality of protrusions 4 having a substantially constant height are provided on the lower surface 1 b of the base 1. According to such a configuration, when the cleaning brush A is used, the protrusion 4 functions as a slip stopper when the base body 1 is gripped by hand. Further, according to the configuration having the plurality of protrusions 4, for example, even when the cleaning brush A is placed on a sink or the like, the lower surface 1 b of the base body 1 does not come into close contact with the sink or the like. It can also function as a slipper when placed in a wet location.

  While specific embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention. The specific shape and material of each part of the cleaning brush according to the present invention are not limited to the above embodiment.

  In the above embodiment, each brush piece group 3A is constituted by six brush pieces 3, but the number of brush pieces 3 constituting the brush piece group 3A is not limited to six. Further, the arrangement of the through holes 2 and the arrangement of the brush pieces 3 are not limited to the above embodiment.

  In the above embodiment, the base body 1 is substantially square. However, as the shape of the base body 1, various shapes such as a long rectangle, a circle, or an ellipse can be adopted.

  In the said embodiment, although the case where the cleaning brush A was used as a cleaning use for kitchens was demonstrated, of course, it is not limited to the said use. The cleaning brush according to the present invention can be used for cleaning purposes other than for kitchens.
