When a user washes clothes, it is relatively often done with foreign matter such as coins in the clothes pocket, but these coins are mixed in the drainage when washing with a washing machine. If it flows out to the drain, coins may get stuck inside the drain.
This is caused by a coin having a diameter larger than the inner diameter of the reduced diameter portion being caught in the reduced diameter portion because there is a reduced diameter portion inside the washing machine drainage channel.
The diameter-reduced portion is connected by inserting one of the drain pipes into the other pipe and connecting them, so that the end of the inner fitting is smaller than the inner diameter of the other pipe. When connecting pipes with the same inner diameter of drain pipes, when connecting via an adapter or socket, the inner diameter of the adapter or socket is smaller than the inner diameter of the drain pipe. It is not provided, it is the result.
In particular, as shown by the broken line in FIG. 5B, the design surface of the coin is orthogonal to the pipe axis direction of the drain pipe inside the drain pipe, and the circumferential portion of the side surface of the coin abuts on the reduced diameter portion. When a coin is caught in the pipe, the inside of the drain pipe is completely closed without a gap (hereinafter, the clogging phenomenon is described as "clogged in a plane with respect to the pipe axis direction"). When such a situation occurs, drainage cannot be performed normally, and in the worst case, drainage may flow back to the indoor side.

Further, in the technique of Patent Document 1, the drainage elbow or the drainage guide pipe is configured in the middle of the drainage flow path for the washing machine in order to prevent the bubbles in the drainage from flowing back onto the waterproof pan. A plurality of reduced diameter portions are formed in the machine drainage flow path. When a plurality of reduced diameter portions are configured in this way, naturally, if coins are mixed in the drainage, the possibility of being caught in the reduced diameter portion increases. However, the drainage elbow or the drainage guide pipe is a configuration that should be adopted for washing machine drainage in which bubbles are often mixed in the drainage, and the configuration cannot be omitted.

Further, in the technique of Patent Document 2, although the elbow member and the drain hose can be easily attached and detached by the attachment member and can be easily cleaned by the user, when coins are clogged inside the drain pipe. Since it is not known which part of the drainage pipe is clogged with coins, it is very difficult for a general user to remove the coins inside the drainage pipe, and if the inside of the drainage pipe is clogged, it is necessary to call a specialist.

From the above, in the present application, coins are clogged in one of the washing drainage routes to prevent drainage, prevent backflow into the room, and collect even if the effect is mixed in the drainage. Provided is a drainage pipe for a washing machine equipped with a coin collecting member capable of easily taking out coins from a washing drainage route even by a general user.

Further, as shown in FIG. 2, the drainage device 1 is provided with a drainage trap function by storing a part of the drainage water inside to prevent the odor and pests from the sewage from flowing back to the indoor side. Further, the drainage device 1 includes a drainage guide pipe 11, a deodorizing cylinder 13, and a deodorizing Owan 14 inside.
As shown in FIG. 2, the drainage device 1 is composed of a drainage port 1a which is an inlet for drainage at the upper end and an outlet 1b which is an outlet of the drainage port 1a at the lower end, and the drainage port 1a is drainage on a waterproof pan. And the drainage from the washing machine 5 flows into the drainage device 1 through the drainage guide pipe 11 and the elbow member 23 described later. A sewer pipe is connected to the outlet 1b.
The deodorant Owan 14 is a bowl-shaped member that is detachably provided inside the drainage device 1, and drainage is stored inside. Further, the lower end of the deodorant cylinder 13 is arranged on the deodorant Owan 14.
The deodorant cylinder 13 is a tubular member whose lower end is located inside the deodorant Owan 14, and its upper end is watertightly and detachably attached to the entrance of the drainage device 1. In addition, the deodorant cylinder 13 and the deodorant Owan 14 cooperate to form a sealing water, and the sealing water has a drain trap function that prevents odors and pests from sewage from flowing back into the room.
The drainage guide pipe 11 is a pipe body connected to the downstream end portion of the elbow member 23 described later, and the lower end side is inside the deodorant Owan 14 and is arranged on the inner circumference of the deodorant cylinder 13. The lower end of the drainage guide pipe 11 constitutes a protrusion in the horizontal direction, and this protrusion is arranged outside the outer circumference of the deodorant cylinder 13, so that the drainage in the drainage guide pipe 11 is discharged from the deodorant cylinder 13. Is forcibly drained to the downstream side. With such a configuration of the drainage guide pipe 11, the washing machine drainage is drained only through the drainage guide pipe 11, so that the detergent bubbles mixed in the drainage are appropriately downstream from the entrance of the drainage device 1 without flowing back. And drained.
As shown in FIGS. 3 and 4, the washing machine drainage channel 2 is composed of a washing machine tube 21, a socket 22, and an elbow member 23, and the inside is a path through which drainage generated from the washing machine 5 passes. ..
The washing machine tube 21 is a hose body made of a flexible tube connected to the washing machine 5, and an elbow member 23 is connected to a downstream end portion via a socket 22 described later.
The socket 22 is a cylindrical tube body, one end of which is internally fitted into the washing machine tube 21 and the other end of which is internally fitted into an elbow member 23 described later. Both ends are tightly connected with a binding band 8 or the like in a watertight manner, and the tightening band is tightened by the user to be detachably connected. In this embodiment, the socket 22 corresponds to the reduced diameter portion 3.
The diameter-reduced portion 3 is a portion provided in an unspecified region of the washing machine drainage channel 2 or the drainage device 1, and is, for example, a connection portion of a pipe body, and as a result, a part of the inner diameter is from the upstream side. It is a portion where the diameter is reduced, a bent portion of the elbow member 23, and a portion where the path of the drainage guide pipe 11 is partially reduced in diameter from the upstream side. Further, in the present embodiment, the reduced diameter portion 3 refers to a portion having the same diameter as the outer diameter of the coin 7 or a smaller diameter than the coin 7. Further, the reduced diameter portion 3 exists on the downstream side of the socket 22 including the socket 22, and therefore, the coin collecting portion member is arranged in the reduced diameter portion 3 or upstream of the reduced diameter portion 3. The diameter-reduced portion 3 is connected by inserting one pipe body of the drain pipe into the other pipe body and connecting the diameter-reduced portion 3, so that the end portion of the inner fitting portion is larger than the inner diameter of the other pipe body. The part where the inner diameter of the drain pipe is smaller than the inner diameter of the drain pipe when connecting via the adapter or socket 22 when connecting pipes with the same inner diameter of the drain pipe.

Connect freely.
The coin 7 is a circular coin cast from metal, and the surface on which the symbol is engraved is referred to as the symbol surface 71. Multiple types of coins 7 are in circulation in Japan. Further, although the coin 7 is described in this embodiment, exactly the same disk shape as the coin 7, such as clothes buttons and medals, foreign coins / coins, and the like are naturally included.
As shown in FIGS. 5 and 6, the coin collecting member 4 is a member for collecting coins 7, and is composed of a cylindrical body having a flange portion 43 at the upstream end portion 42, and has a convex portion on the inner peripheral surface. A plurality of 41 are configured. The coin collecting member 4 is fitted inside the socket 22 and is detachably attached. The coin collecting member 4 in this embodiment is fitted inside the socket 22, but is arranged so that the collar portion 43 of the coin collecting member 4 engages with the end portion of the socket 22.
The convex portion 41 is formed on the inner peripheral surface from the lower end of the coin collecting member 4, and includes a convex portion 41b protruding in the axial direction and a convex portion 41a protruding along the circumference.
A plurality of convex portions 41b protruding in the inner peripheral direction in the axial direction are formed in the inner circumference of the coin collecting member 4 in the axial direction. Further, since the distance from the upstream end 42 of the coin collecting member 4 to the upstream end of each convex 41b is configured to be different for each convex 41b, the coin 7 has a coin 7. The symbol surface 71 of the coin 7 is collected by the coin collecting member 4 at an angle other than perpendicular to the flow path. Further, when the upstream end portions of the three or more convex portions 41b are at the same position with respect to the upstream end portion 42 of the coin collecting member 4, the coin 7 is supported by the upstream end portion of the convex portion 41b. In this way, the design surface 71 of the coin 7 may become flat with respect to the pipe axis direction and be clogged. However, in this embodiment, as shown in FIG. 6, the upstream end of the convex portion 41b is the coin collecting member 4. Since there are up to two convex portions 41b at the same position with respect to the upstream end portion 42 of the coin 7, the coin 7 is not supported by the end portion of the convex portion 41b, and the symbol surface 71 of the coin 7 is flat with respect to the pipe axis direction. It doesn't get stuck. Therefore, since the coins 7 are collected at an angle with respect to the pipe axis direction inside the drainage pipe, a water passage gap can be provided inside the drainage pipe, and even if the coins 7 are mixed in the drainage, the drainage can be done. It becomes possible to do.
Further, the convex portion 41a projecting in the circumferential direction of the coin collecting member 4 has a relatively small diameter such as 1 yen or 5 yen for the purpose of being able to collect even various outer diameters of the coin 7. Even in the case of the coin 7, the outer diameter of the coin 7 abuts on the circumferential convex portion 41a and is configured to collect the coin 7.

When drainage is generated from the washing machine 5, it passes through the inside of the socket 22 connected to the end of the washing machine tube 21 from the washing machine tube 21 which is the washing machine drainage channel 2. At this time, the drainage passes through the coin collecting member 4, and the drainage flows into the elbow member 23 to which the end of the socket 22 is connected. The drainage from the elbow member 23 passes through the drainage guide pipe 11, passes through the elbow member 23, and flows into the drainage device 1.
When drainage is generated on the washing machine waterproof pan, the drainage flows into the drainage device 1 from the drainage port 1a of the drainage device 1 and passes between the outer circumference of the drainage guide pipe 11 and the inner circumference of the deodorant cylinder 13. Passing between the lower end of the deodorant cylinder 13 and the bottom surface of the deodorant Owan 14, passing between the outer circumference of the deodorant cylinder 13 and the inner surface of the deodorant Owan 14, drainage overflows from the upper end of the deodorant Owan 14 and is drained to the outside of the drainage device 1. It becomes.
Further, the wastewater stored in the deodorant Owan 14 forms a sealing water by the deodorant Owan 14 and the deodorant cylinder 13.
At this time, even if a large amount of bubbles are mixed in the drainage from the washing machine 5, the drainage mixed with bubbles flows directly into the sealing water from the drainage guide pipe 11, so that the bubbles in the drainage are drained by the drainage device. There is no backflow from the drain port 1a of 1 or backflow into the washing machine 5.

When the coin 7 flows into the drainage, it is collected by the coin collecting member 4 arranged in the socket 22 of the washing machine drainage flow path 2 as shown in FIG. At this time, the outer circumference of the coin 7 abuts on the coin collecting member 4 with the convex portion 41b formed in the axial direction on the inner circumference of the coin collecting member 4, and the symbol surface 71 of the coin 7 is substantially parallel to the pipe axis direction. The coin 7 fits in the gap between the convex portions 41b in the axial direction. At this time, the axially convex portion 41b of the coin collecting member 4 sets the distance from the upstream end 42 of the coin collecting member 4 to the upstream end of each convex 41, respectively. Since the coin collecting member 4 is configured to be different for each, the distance from the upstream end portion 42 of the coin collecting member 4 to the convex portion 41b is larger than the same distance of the other convex portions 41b. Collected so as to incline to the side. In this way, since the design surface 71 of the coin 7 is not flat with respect to the pipe axis direction and is collected at an angle, the inside of the drain pipe is not blocked by the coin 7, and the drainage is smoothly drained downstream. Will be done.

Further, the coin collecting member 4 can be easily cleaned and maintained. When cleaning or maintenance is desired, the socket 22 is pulled out from the washing machine tube 21 of the washing machine drainage channel 2 as shown in FIG. 4, and the coin collecting member 4 attached to the inside of the socket 22 is removed. The coins 7 collected by the coin collecting member 4 are taken out, and the coin collecting member 4 is cleaned. When the maintenance and cleaning of the coin collecting member 4 are completed, the coin collecting member 4 is attached to the inside of the socket 22 and the washing machine tube 21 is connected to the socket 22 to form the washing machine drainage flow path 2. .. By doing so, the coin collecting member 4 can be easily attached to and detached from the washing machine drainage channel 2 even by a general user, so that the collected coins 7 can be easily taken out or the coin collecting member 4 can be easily removed. Can be cleaned.
