Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drainage device for connecting a drainage path from a washing machine pan to a drainage pipe of a building.

[0002]

[Prior Art]

 The pan on which the washing machine is placed will have a drainer installed to guide the drainage of the washing machine to the drainage pipe of the building. This drainer is fixed to the bottom of the pan in a position away from the main body of the washing machine, the drain hose of the washing machine is inserted from above, and the pipe is connected to the drain pipe of the building. Then, in order to prevent the backflow of the bad smell from the drainage, a trap is generally provided in the internal flow path.

In the drainage device for a washing machine, bubbles due to detergent are contained in the drainage from the washing machine, and thus the bubbles overflow from the eye dish at the upper end of the drainer and flow into the pan during drainage. Sometimes. This is partly because only bubbles are left behind because there is a trap in the drainage device where the flow path bends in a U shape.

In order to solve such a problem, there is a drainer disclosed in Japanese Utility Model Publication No. 62-27572 as a drainage device in which bubbles quickly flow into a drainage pipe of a building. Instead of directly connecting the hose of the washer to the internal flow path of the drain, a drain pipe that opens the flow path at the bottom of the trap is installed, and the drain pipe is directly drained to the outlet of the trap. It is a structure that drains out. With this structure, even if the drainage contains bubbles, it is possible to prevent bubbles from remaining and overflowing to the side of the dish, and it is possible to keep the area around the drainer clean.

[0005]

[Problems to be solved by the device]

 In the one described in the above publication, a drainage guide pipe having a rectangular vertical cross-section is integrated with the lower end of the drainage pipe, and the drainage pipe is extended in a radial direction orthogonal to the pipe axis of the drainage pipe. Therefore, the drainage from the hose flows through the drainage pipe directly below, and is then sharply bent at the inlet of the drainage guide pipe and discharged as two separate flows.

However, since the drainage pipe is a conduit to the end of the flow path, there is no escape place for bubbles contained in the drainage, and bubbles tend to gradually accumulate on the upper side of the drainage pipe. In particular, as the flow path bends significantly toward the drainage guide pipe, bubbles contained in the drainage may remain in the drainage pipe without being bent, and this may flow over the pan and flow out onto the pan.

[0007] Thus, even if an attempt is made to discharge the drainage containing bubbles at the bottom of the trap to prevent the backflow of bubbles, if the flow path and the bend that trap the bubbles are large, the flow rate of the drainage and the detergent Backflow of bubbles cannot be completely prevented depending on the concentration.

The problem to be solved in the present invention is to effectively prevent the backflow of bubbles to the side of the perforated plate by promptly discharging the drainage to the trap so that bubbles are less likely to remain.

[0009]

[Means for Solving the Problems]

 The present invention relates to a drainer having a trap connected to a drainage flow path from a washing machine and having a guide pipe for guiding the drainage from the washing machine to a bottom portion in the trap, which is provided at a lower end of the guide pipe. It is characterized by having a wing-shaped spacer block that sits on the bottom wall of the main body of the drainage device.

[0010]

[Action]

 Since the guide pipe is placed on the bottom wall of the main body by the spacer block, drainage will naturally flow into the bottom of the trap without bending the flow path from the lower end of the guide pipe. For this reason, bubbles do not remain in the guide pipe, fluidization of the drainage flow from the trap to the downstream is also promoted, and backflow of bubbles to the upstream side of the trap is prevented. ..

【Example】

 FIG. 1 is a vertical sectional view of a drainage device for a washing machine of the present invention fixed to a pan, and FIG. 2 is a plan view of the drainage device.

In the figure, a body 1 of a drainer is fixed to the bottom of a washing machine pan 50, and an adapter 2 for connecting a hose 51 of a washing machine (not shown) is connected to the body 1. I am making it. The main body 1 has a substantially cylindrical shape with an open upper end, and is fixed to the lower surface of the pan 50 by screwing the fixing flange 3 inserted into the mounting opening 50a opened in the pan 50 from above.

Inside the main body 1, an annular partition wall 1a that is coaxially erected from the bottom wall is formed, and a peripheral wall is provided with a socket 1b for connecting to a drainage pipe (not shown) of a building. .. In addition, the drain cylinder 4 is coaxially fixed to the fixing flange 3 by screwing, and a perforated plate 5 is incorporated at the upper end.

The drain 4 has its lower end opened, and is dropped coaxially into the partition wall 1 a as shown in FIG. 1, and the opening at the lower end is separated from the bottom wall of the main body 1 by a distance. Is located. As shown in FIG. 2, the eyelet 5 has a large number of holes 5a formed therein, and the adapter 2 is connected to the center of the eyelet 5 to communicate with the main body 1.

Further, a guide pipe 6 for guiding the drainage containing bubbles from the hose 51 into the main body 1 is provided. As shown in the perspective view of FIG. 3, the guide tube 6 has a circular flow passage tube 6a having an upper end connected to the adapter 2 to connect the flow paths, and an annular tube provided at the lower end of the flow path tube 6a. Of the flange 6b. On the outer circumference of the flange 6b, an annular wall 6c is provided which is erected on the same axis as the flow path cylinder 6a. The lower end of the drainage pipe 4 abuts against the inner wall of the annular wall 6c, and three restraint seats 6d for restraining the guide pipe 6 are provided at the inner surface of the annular wall 6c. Three spacer blocks 6e protruding downward from the same portion are formed.

As shown in FIG. 1, the guide tube 6 is coaxially arranged in the partition wall 1 a of the main body 1, and the spacer block 6 e is incorporated in a state of being placed on the bottom wall of the main body 1. Then, when the flow channel cylinder 4 is connected to the fixed flange 3 by screwing, the lower end of the drainage cylinder 4 contacts the restraining seat 6d, whereby the guide tube 6 is fixed to the main body 1. At this time, a gap is created between the lower end of the guide tube 6 and the bottom wall of the main body 1 by the spacer block 6e, and the lower end of the drainage pipe 4 enters the annular wall 6d and is located immediately above the flange 6b. Like Further, the lower end of the drain tube 4 enters the annular wall 6c of the guide tube 6 so that the drainage from the hose 51 communicates with the socket 1b side with a gap between the drainage tube 4 and the upper surface of the flange 6b.

In the above structure, the drainage water from the hose 51 flows into the partition wall 1 a of the main body 1 from the flow passage cylinder 6 a of the guide pipe 6, and the flow passage having an annular cross section in the partition wall 1 a and the drain pipe 4 is formed. To rise. Then, when it exceeds the partition wall 1a, it passes through the socket 1b from the inside of the main body 1 and flows away into the drainage pipe of the building.

The drainage flowing from the guide pipe 6 into the main body 1 directly flows from the flow channel cylinder 6 a into the bottom portion of the main body 1 surrounded by the partition wall 1 a, and then is discharged through the outside of the drain cylinder 4. Therefore, the drainage water flowing out of the guide tube 6 is blocked from the side of the dish 5 by the drainage tube 4, and even if the drainage contains bubbles, it does not flow back to the side of the dish 5. Therefore, it is possible to suppress the generation of bubbles overflowing from the plate 5 and to prevent the upper surface of the pan 50 from being wet with drainage. If the drainage overflows to the side of the pan 50, this drainage flows down into the drainage pipe 4 from the hole 5a of the plate 5 and passes through the gap between the lower end of the drainage pipe 4 and the annular wall 6c to the partition wall. It is discharged into 1a.

Here, the drainage containing bubbles flows down from the lower end of the guide tube 6 to the bottom of the main body 1, and then flows downstream from the gap formed by the spacer block 6e. Since the spacer block 6e has a wing shape extending in the radial direction, the resistance against drainage flowing out is small. Further, since the flow path does not have a sharp bend and is not a closed flow path in a tubular shape, bubbles do not accumulate at the lower end portion of the guide tube 6 or remain inside thereof. Therefore, the bubbles quickly flow out into the partition wall 1a together with the drainage, and the flow thereof is promoted.

As described above, even if the drainage contains bubbles, the drainage quickly flows off from the guide pipe 6 to the downstream side, so that there is a gap between the lower end of the drain pipe 4 and the flange 6b at the lower end of the guide pipe 6. It is also possible to prevent bubbles from flowing back to the side of the plate 5 from the gap. Therefore, as compared with the conventional example in which the flow path end of the guide tube 6 is closed or sharply bent, the drainage containing bubbles naturally flows, and the backflow of bubbles is more effective. Can be prevented.

Although the socket 1b is provided on the peripheral wall of the main body 1 in the embodiment, the discharge end may be provided on the lower end of the main body 1 instead.

[0022]

[Effect of the device]

 In the present invention, since the spacer block provided at the lower end of the guide tube allows a gap to be formed between the guide tube and the bottom wall of the main body, it is not necessary to bend or close the flow path end of the guide tube. For this reason, bubbles in the wastewater flowing from the guide pipe can be quickly discharged without remaining in the guide pipe, and the backflow of bubbles to the side of the dish can be prevented. Further, since it is only necessary to provide the guide tube with the spacer block like a wing, there is no need for a bifurcated flow path as in the conventional case, and the manufacture of the guide tube is simplified.
