The cleaning unit of the present invention has the following effects (1) to (5).
(1) In the present invention described in claim 1, the amount and pressure of the cleaning water ejected from the cleaning hole for the following reason is provided by providing a stirring body that moves along the water supply groove in the unit body. Intentionally changes (unevenness) are generated to perform effective and efficient cleaning.
As shown in FIG. 4, the stirring body advances in the axial direction on the water supply groove in the cleaning unit under the pressure of the cleaning water flowing inside the cleaning unit.
At this time, as shown in FIG. 5, the washing water that has flowed over the stirring body in the advancing direction of the stirring body causes the air to flow into the interior by stirring the stirring body when the washing water has passed over the stirring body. Takes in and contains foam. When the washing water containing bubbles is ejected from the washing hole, the washing water ejected from the washing hole, the amount of water, and the water pressure change variously depending on how the bubbles bounce, and are not uniform ( The amount of water and water pressure are less than the amount of washing water ejected from the washing holes not affected by the stirring body, and the pressure tends to decrease).
For this reason, as in the conventional example, only a specific part of the drain port member is washed and the other parts are not washed, and the washing water can be effectively bathed as a whole. become.
In addition, as described in claim 2, when the stirrer has a shape that is easy to rotate, such as a spherical shape, the stirrer advances while rotating in the unit main body, so that it is possible to generate washing water mixed with bubbles more effectively. it can.
On the other hand, the washing water that flows into the lower side of the stirring body is because the stirring body functions like a wall and a large amount of washing water accumulates, or the flow path becomes narrower and the pressure increases accordingly. The amount of water is larger than that of the washing water ejected from the washing hole not affected by the stirring member, and the pressure is also high. For this reason, there is a slight change in the flow of the cleaning water, and as described above, the cleaning water is slightly washed and easily cleaned by the foam mixed washing water ejected from the cleaning holes in the advancing direction of the stirring body. Since the dust and slime in the wet state are exposed to the washing water having a larger amount of water and higher pressure than usual, washing can be performed more effectively than the conventional technique. When the stirrer is a sphere, this cleaning action is confirmed based on various experimental data. As described in claim 3, the area of the hollow portion in the cross-sectional shape of the unit body and the surface passing through the center of the stirrer When the ratio of the cross-sectional area to the cross-sectional area of the unit main body: the cross-sectional area of the unit body: the cross-sectional area of the stirring member = 3: 1, the effect was most effective.

Embodiments of the present invention will be described below with reference to the drawings.
The embodiment of the present invention shown in FIGS. 1 to 3 relates to a sink (K) which is a drainage device as shown in FIG. 9, and is a sink (S) which is a tank body described below. , And a trap-integrated drain port member (D) provided on the bottom surface of the sink (S), and a washing unit mounted on the drain port member (D) as necessary.
The sink (K) has a sink (S) that is a tank body having an opening on the bottom surface, and has a bottomed cylindrical shape attached to the opening of the sink (S) and has an opening for drainage at the lower end of the side surface. A drain port member (D) and a cabinet (C) that houses and arranges each member including a drain pipe (P) inside are provided.
The drain port member (D) is a member having a bottomed cylindrical shape and having a drain opening at the lower end of the side surface, and the drain pipe (P) is connected to the outlet (D1) provided below the side surface.
The drainage pipe (P) is a general term for members that combine the drainage port member (D) and the underfloor pipe and that combine pipes and the like.
The cleaning unit is a member that is attached to the opening above the drain port member (D) during use in order to clean the inside of the drainage device, and includes a unit main body (1) and a unit main body (1) described below. And a stirring body (5) made of a material having a specific gravity greater than 1 provided therein.
The unit main body (1) includes a unit main body (1) formed of a hollow body having a substantially ring shape and a substantially rectangular shape in cross section in a plan view, and a water supply groove provided on the bottom surface of the hollow body of the unit main body (1) ( 2) and a cleaning hole (3) provided in the drainage groove, and further connected to the upper surface of the unit body (1) in a tangential direction with respect to the substantially ring shape of the unit body (1) in plan view. And a connecting tube (4) through which pressurized washing water is poured. This pressurized wash water can be easily obtained by connecting a general water tap (faucet) to the connection tube (4) and opening it, for example. The cleaning hole (3) is a small opening having a circular shape in the axial direction with a diameter of about 1 mm, and about three holes are provided per 1 cm on the water supply groove (2).
The ratio of the area of the hollow portion in the cross-sectional shape of the unit body (1) and the cross-sectional area of the surface passing through the center of the stirring body (5) is the cross-sectional area of the unit body (1): The cross-sectional area is 3: 1. This is to obtain the maximum foaming effect by the stirrer (5), which will be described later.
Further, in order to obtain this foaming effect, a structure for supplying air to the unit main body (1) is required. In this embodiment, intake ports (7) for supplying air into the unit main body are provided at four positions on the upper surface of the unit main body (1). Particularly in this embodiment, as shown in FIGS. 6 and 7, the unit main body is configured so that the cleaning water in the unit main body (1) does not overflow from the intake port (7) and air can be easily taken in. (1) An inclination is provided so as to follow the flow direction of the cleaning water. With this configuration, when there is a flow of cleaning water (solid arrow in FIG. 7) in the unit main body (1), a flow (indicated by a one-dot chain line in FIG. 7) that draws air into the unit main body (1). Arrow) occurs, and air can be naturally drawn into the unit main body (1).
The stirrer (5) is a spherical metal material with a specific gravity of 1 or more that rolls on the drainage groove in response to the flow of cleaning water flowing in the unit body (1), and the surface is coated with rust to prevent rust. It becomes.
Furthermore, the cleaning unit of the present invention includes a guide body (8) for fixing the unit main body (1) to a fixed position on the inner surface of the drain port member (D).

Each said member is connected to the drain outlet member (D) of the sink (K) which is drainage equipment as follows.
The drain port member (D) is watertightly connected to the opening of the bottom surface of the sink (S) which is a tank body, and the outlet (D1) of the drain port member (D) is further connected to the drain pipe (in the cabinet (C)). Connecting to the underfloor piping via P), the construction of the washing stand of this embodiment is completed.

In the sink configured as described above, when dust or slime is generated in the drain port member (D) by using the sink (K), the cleaning unit is attached to the drain port member (D). In this case, the cleaning unit is mounted on the optimum position of the drain port member (D) by the guide body (8). Next, the faucet (faucet) of the sink (K) is connected to the connection tube (4) through the tube tube (9). From this state, the faucet is opened, and water discharged under water pressure is allowed to flow inside the cleaning unit to obtain cleaning water.
In this embodiment, since the connecting tube (4) is connected in a tangential direction with respect to the circular shape of the unit body (1) in plan view, when washing water is passed, the unit body (1) is seen in plan view. A flow that flows in a certain direction occurs in the washing water along the circular shape of the.
At this time, since the specific gravity of the stirring member (5) is larger than 1, the stirring member (5) does not float against the washing water flowing into the unit main body (1), but the circular shape in plan view of the unit main body (1). It is rolled by rotating in the unit main body (1) by being pushed by the momentum of the flow of cleaning water along a certain direction. And the washing water which flowed into the unit main body (1) by this rotating stirring body (5) goes through one of the following three processes into the drain port member (D) from the washing hole (3). Erupted.
1. The washing water ejected from the washing hole (3) at a position not affected by the stirring body (5) corresponds to the amount of water, water pressure (pressure applied from the faucet in the unit body (1)), and opening area. The water is ejected from the cleaning hole (3) with a stable amount of water and momentum. In this case, since the cleaning water is exposed to a fixed position of the drain port member (D), cleaning of the exposed portion of the drain port member (D) is performed intensively, but cleaning of other portions is performed. It is hardly done because it is not exposed to water.
2. In the washing hole (3) immediately before the agitating body (5) in the traveling direction, the washing water exceeding the upper part of the agitating body (5) flows into the washing hole (3). At this time, when the washing water flowing in the traveling direction of the stirring member (5) exceeds the stirring member (5), the surface of the stirring member (5) The air is taken into the washing water by stirring and becomes bubbled. When the washing water containing bubbles is ejected from the washing hole (3), since the foam contains bubbles, the flushing method, the amount of water, and the water pressure of the washing water ejected from the washing hole (3) vary depending on how the bubbles bounce. (The amount of water and the water pressure are less than the amount of washing water ejected from the washing hole (3) not affected by the stirring member (5), and the pressure tends to decrease).
For this reason, only the specific part of the drain port member (D) is washed and the other parts are not washed, and the washing water is effectively supplied to the entire drain port member (D). Can be bathed.
In addition, when the stirrer is a sphere, the cleaning action due to the mixing of bubbles is confirmed based on various experimental data. When the stirrer is a sphere, the area of the hollow part in the cross-sectional shape of the unit body (1) The case where the ratio of the cross-sectional area of the surface passing through the center of the shape to the cross-sectional area of the unit main body (1): the cross-sectional area of the stirring body (5) = 3: 1 worked most effectively.
Further, the air in the unit body (1) is consumed by the above-mentioned jet of washing water mixed with bubbles, etc., but in this embodiment, the air inlets (7) are provided at four locations on the upper surface of the unit body (1), Since air is taken in from the intake port (7), the air in the unit body (1) is not completely lost. In particular, in this embodiment, as shown in FIG. 6, since an inclination is provided along the flow direction of the cleaning water in the unit main body (1), the inside of the unit main body (1) is formed from the intake port (7). When the cleaning water does not overflow and there is a flow of cleaning water in the unit main body (1), air can be naturally drawn into the unit main body (1).
3. In the cleaning hole (3) immediately below the stirring body (5) or close to the rear in the traveling direction, the cleaning water flows into the cleaning hole (3) so as to sink under the stirring body (5). At this time, as indicated by the solid line arrow in FIG. 5, the washing water flowing into the washing hole (3) immediately below the stirring body (5) or close to the rear with respect to the traveling direction is the wall of the stirring body (5). As a result of the fact that a large amount of washing water was accumulated and the flow path was narrowed and the pressure increased accordingly, The amount of water is large and the pressure is high as compared with the cleaning water ejected from the cleaning hole (3) not affected by the stirring member (5) as described in (1). For this reason, some changes occur in the flow of the washing water, and Dust and slime that have been slightly washed with the foam-blown washing water ejected from the washing hole (3) in the direction of travel of the stirring body (5) as described in the above, Because it will be exposed to a large amount of water and high pressure washing water. Cleaning can be performed more effectively than the cleaning water in this state.

  In the drain port member (D), among the above paragraphs 0017, 1. ~ 3. The drain port member (D) is sequentially cleaned through the processes described in the above. If water is allowed to pass through the washing unit for a sufficient period of time, particularly, in paragraph 2 of paragraph 0017. And 3. Through this process, the inside of the drain port member (D) is effectively cleaned over the entire inner surface, and dust and slime inside can be cleaned and flowed downstream.

The embodiment of the present invention is as described above, but the embodiment of the present invention is not limited to the above, and can be freely changed without departing from the gist of the invention.
For example, in the above embodiment, the cleaning unit is positioned and arranged on the drain port member (D) by the guide body (8). Although not particularly shown, the cleaning unit is integrated into the drain port member (D) for cleaning. Water may be passed through the cleaning unit when necessary. In this way, the opening of the drain port member (D) is slightly reduced, but the interior of the drain port member (D) can be cleaned by a simple operation of simply passing water through the cleaning unit when necessary.

Moreover, you may incorporate a washing | cleaning unit in the cover member (6) for water-stopping the drain port member (D) like the Example shown in FIG.
In this way, since the washing water is allowed to flow inside after completely closing the opening of the drain port member (D), the washing water does not overflow or scatter in the sink (S). It can be used as a suitable cleaning unit for a person.

  Further, in this embodiment, the shape of the unit body (1) is circular in plan view as in the embodiment shown in FIG. 2, but the present invention is not limited to the above embodiment, and the drain port In combination with the shape of (D), the shape may be, for example, a substantially elliptical shape in plan view, or a polygonal shape such as a substantially square shape in which the corners are provided with arcs so that the stirrer (5) can move along the flow. .

Further, in this embodiment, as shown in FIG. 6, the intake port provided on the upper surface of the unit body (1) is provided with an inclination along the flow direction of the cleaning water in the unit body (1). However, the present invention is not limited to the above-described embodiment. For example, the structure for intake may be omitted, and intake from the faucet side or intake from the cleaning hole (3) may be adopted.
Even when the intake port is provided, a structure other than the above-described embodiment, for example, a backflow prevention valve for preventing a backflow from the inside of the unit main body (1) may be provided in the intake port (7).
