Trash collecting device for drain port

Abstract

To provide a trash collecting device for a drain port capable of solving the following problems: (1) in a conventional device, trash separated from drainage accumulates on an upper surface of a mesh-shaped portion so that, as an amount of the separated trash increases, the trash blocks openings of the mesh-shaped portion to cause a clogged state that inhibits a flow of drainage; and (2) a part of slender trash such as hair passes partway through the openings of the mesh-shaped portion, thereby causing the trash to become entangled with the mesh-shaped portion and making the trash difficult to remove therefrom.SOLUTION: A trash collecting device that is detachably attached to a drain port, wherein a drain passage extending longitudinally in a vertical direction is formed in a peripheral wall of a cylindrical body surrounding the drain port in a state of being installed in the drain port, and a collecting member is provided such that, when drainage passes through the drain passage from an outer side toward an inner side, trash contained in the drainage is separated and collected on an outer side of the peripheral wall.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a drain dust collector that is attached to a bathroom drain or the like to separate and collect dust such as hair contained in the drain. [Background technology]

[0002] Conventional drain garbage collectors of this type have a sieve-like portion at the bottom, and the wastewater flows down the top of the sieve-like portion along with the garbage, and the wastewater flows downward through the sieve-like portion, thereby filtering out the garbage contained in the wastewater (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2023-48818 A (Fig. 2) Summary of the Invention [Problem to be solved by the invention]

[0004] In the conventional drains, the debris separated from the wastewater accumulates on the top surface of the sieve, and as the amount of separated debris increases, the debris blocks the openings of the sieve, causing a so-called clogged state and impeding the flow of wastewater. Also, some long, thin debris such as hair passes partway through the openings of the sieve, causing the debris to become tangled in the sieve, making it difficult to remove.

[0005] In view of the above problems, the present invention aims to provide a garbage collector for a drain that is less likely to obstruct the flow of wastewater even when the amount of garbage separated from the wastewater increases, and that makes it easy to remove collected garbage. [Means for solving the problem]

[0006] In order to solve the above problems, the drain dust collector of the present invention is a drain dust collector that separates and collects dust from wastewater flowing into a drain, and is characterized in that it is detachable from the drain, and has a drain passage formed in the peripheral wall of a cylinder surrounding the drain that is longitudinal in the vertical direction when installed in the drain, and a collection member is provided that separates and collects dust contained in the wastewater on the outside of the peripheral wall as the wastewater passes through this drain passage from the outside to the inside.

[0007] Conventional collectors have sieve-shaped openings, and wastewater is poured over the entire surface of the openings to strain out debris from the wastewater. This means that all of the openings become uniformly clogged with debris, rendering the collector inoperable. In contrast, with the above-described configuration, the drainage passage that separates and collects debris from the wastewater is longitudinal in the vertical direction, so even if the lower part of the drainage passage becomes clogged with debris, the upper part remains open. As a result, the drainage passage gradually becomes clogged from the bottom to the top.

[0008] In order to collect dirt uniformly in the circumferential direction on the outer peripheral surface of the collection member and increase the amount of collection, a water guide member may be provided to direct wastewater in one direction along the peripheral wall of the collection member.

[0009] In order to avoid the need to frequently remove the collected dust from the collecting member, a dust remover having a dust removal protrusion inserted from the inside of the peripheral wall to the outside may be provided in the drainage passage so as to be movable vertically inside the peripheral wall of the collecting member, and the dust separated on the outside of the peripheral wall may be compressed downward by this dust removal protrusion.

[0010] In order to make it easier to remove debris from the collection member, the collection member may be detachably attached to the water guide member, and the debris collected on the outer surface of the collection member may be removed when the collection member is removed from the water guide member. [Effects of the Invention]

[0011] As is clear from the above description, the present invention filters out debris from wastewater using a drainage passage that is vertically long, so the entire drainage passage is not blocked at the same time, and the flow of wastewater can be ensured. [Brief explanation of the drawings]

[0012] [Figure 1] FIG. 1 shows a configuration of an embodiment of the present invention. [Figure 2] Plan view showing the flow of drainage water through the water guide member [Figure 3] A cross-sectional view showing how dust is captured by the capture member. [Figure 4] Diagram showing the compressed state of garbage [Figure 5] Diagram showing the state of dust removal DETAILED DESCRIPTION OF THE INVENTION

[0013] 1 to 3, reference numeral 1 denotes an example of a capture member according to the present invention. This capture member 1 is detachably engaged with a water-conducting member 2. This water-conducting member 2 is attached to a drain outlet 42. Drain outlet 42 opens into a drain section 41, which is a recess formed in the bathroom floor 4. Wastewater flowing over floor 4 flows into this drain section 41 and then into drain outlet 42, before being discharged into the sewer through drain pipe 44. Drain pipe 43 is connected to the bathtub, and water from the bathtub is drained from this drain pipe 43 into drain pipe 44. Reference numeral 46 denotes a drain, and the lower end of drain outlet 42 is set below the water level 45 of drain 46, preventing pests and bad odors that flow back through drain pipe 44 from entering the bathroom.

[0014] The water guide member 2 is provided with a water guide wall 21, which rotates the wastewater clockwise when viewed from above, and causes it to flow along the outer circumferential surface of the collection member 1.

[0015] The collection member 1 has an upper annular portion 11 at its top and a similarly annular lower annular portion 12 at its bottom. The collection member 1 is detachably connected to the water guide member 2 by engaging an engaging protrusion 22 formed on the water guide member 2 with the outer circumferential surface of the lower annular portion 12. The upper annular portion 11 has a larger diameter than the lower annular portion 12, and the two annular portions are connected by a fin-shaped connecting blade 13. The connecting blade 13 is formed at an angle so that the wastewater flowing from the outside to the inside of the collection member 1 rotates counterclockwise, so that even if debris becomes clogged in the drainage passages formed between the connecting blades 13, the debris will be removed by the flow of wastewater from the outside.

[0016] A dust remover 3 is disposed inside the dust collection member 1. The dust remover 3 has an annular portion 31 with dust removal protrusions 33 extending radially outward from the annular portion 31. Each dust removal protrusion 33 is inserted into a drainage passage formed between the connecting wings 13. The dust remover 3 is therefore held in the dust collection member 1 and is movable up and down along the drainage passage. A handle 32 is connected to the annular portion 31 of the dust remover 3. The handle 32 can be moved between the reclined position shown in the figure and an upright position rotated 90 degrees from that position, and is equipped with a mechanism for locking the handle in both the reclined and upright positions. When the dust remover 3 is raised and the handle 32 is lowered, the dust remover 3 is held in the raised position.

[0017] When the wastewater passes through the drainage passage of the collection member 1, the dust 5 mixed in the wastewater is filtered onto the outer peripheral surface of the collection member 1 and collected, as shown in FIG.

[0018] The collected debris 5 gradually blocks the drainage passage from the bottom, but the top of the passage is not blocked, so the wastewater flows through the top of the passage to drain outlet 42, and the entire drainage passage is not blocked at the same time. However, if the amount of trapped debris 5 increases, by pushing down debris remover 3 as described above as shown in Figure 4, the debris removal protrusions 33 extending radially from debris remover 3 will push down and compress the debris 5, and then by pulling debris remover 3 back up to its original position, the blockage of the drainage passage can be alleviated.

[0019] Furthermore, once the dust 5 has been pressed downward several times in this manner and compressed, as shown in Figure 5, it is possible to remove the collection member 1 from the water guide member 2 and push down the dust remover 3 to remove the accumulated dust 5 from the collection member 1. Note that because the dust remover 3 is simply inserted into the collection member 1 from above, it can be easily removed from the collection member 1 by pulling it upward. Therefore, the dust remover 3 does not necessarily have to be attached to the collection member 1 during normal use.

[0020] The present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention. [Explanation of symbols]
