Description

  The present invention relates to a drain trap, a valve member, and a flow path unit.

  Conventionally, there is a drain trap that is attached to a waterproof pan and discharges drainage discharged from a washing machine to a drain pipe.

  Referring to FIG. 8 illustrating the principle of drainage, the drain trap is connected to the washing machine and the water supply facility in addition to the first channel for discharging the drainage discharged from the washing machine from the channel cylinder to the basket storage part. A second flow path is provided for discharging the drainage leaked into the waterproof pan to between the flow path cylinder and the sealed water cylinder to the storage part of the bag. The drain trap prevents the odor in the flow path from reaching the upstream side by discharging the drain to the downstream drainage pipe while temporarily storing the drainage by the storage section provided in the basket. That is, the drain trap cuts off the ventilation of the first flow path and the second flow path on the upstream side and the ventilation of the third flow path on the downstream side across the storage portion of the soot filled with drainage. doing.

  The first flow path includes a flow path upstream of the drain trap (for example, a drain hose of a washing machine). The third flow path includes a flow path (for example, a drain pipe) on the downstream side of the drain trap.

  By the way, when draining wastewater containing a large amount of washing foam, after drainage passes through the reservoir from the first flow path of the drainage trap, the drainage pipe connected to the drainage trap has a flow velocity higher than drainage. Slow washing foam may remain and the washing foam may block the third flow path. When the third channel is blocked by a large amount of drainage or drainage containing a large amount of washing foam, the pressure in the channel increases. In such a state, the waste water discharged from the washing machine passes through the first flow path, and then is not discharged from the storage section to the third flow path in a state where the internal pressure is high, but from the storage section to the atmospheric pressure. It will flow backward toward the 2nd flow path of the state.

The trough 101 accommodates the channel cylinder 102 in a state of being separated from the bottom surface 101a. The gutter 101 includes a plurality of openings 101c at the top of the side surface 101b. The drainage W stored in the basket 101 overflows from the opening 101c of the basket 101 and flows out to the discharge part 105b of the housing 105 when the discharge of the drainage W from the washing machine 500 proceeds and the water level rises.

  The basket 101 is provided with a storage part 101d for storing the waste water W discharged from the washing machine 500. The storage unit 101d discharges the waste water W to the downstream side while temporarily storing the odor, so that the odor in the third flow path L3 flows backward through the second flow path L2 and the first flow path L1. It is designed not to leak outside. That is, the storage part 101d filled with the waste water W blocks the ventilation of the first flow path L1 and the second flow path L2 on the upstream side and the ventilation of the third flow path L3 on the downstream side. . The third flow path L3 includes a flow path (for example, a drain pipe) on the downstream side of the drain trap 100.

The opening / closing part 104 </ b> P includes a side wall 104 b that protrudes in an annular shape upward from the outer edge in the radial direction of the sealing cylinder 103. The deforming part 104Q is connected to the opening / closing part 104P so as to surround the discharge port 104a, and is curved outward in the radial direction of the opening / closing part 104P so as to be easily deformed. Further, the side wall 104S protruding annularly upward from the upper end of the curved portion of the deformable portion 104Q is inserted between the lower end portion 102b of the channel cylinder 102 formed in a cylindrical shape and the pedestal 106. That is, the valve member 104 is disposed in a state of being suspended from the flow path cylinder 102 via the deformable portion 104Q.

  As shown in FIG. 5A, the opening / closing part 104 </ b> P is separated from the lower part 103 b of the sealing tube 103 when moved to the open position OP that opens the region R. As shown in FIG. 5B, the opening / closing part 104 </ b> P is in contact with the lower part 103 b of the sealing cylinder 103 when moved to the closed position CL that closes the region R.

  The housing 105 is shown in FIG. The housing 105 supports the drainage joint 108 that discharges the drainage W to the flow path tube 102 while accommodating the eaves 101 and the like. The housing 105 is called a trap body and is attached to the waterproof pan 600. The casing 105 is formed in a cylindrical shape with the lower part closed, and accommodates a bag 101 or the like inserted from the upper part. The housing | casing 105 is equipped with the discharge part 105b formed in the cylindrical shape which protruded toward the side from the outer peripheral surface.

  The pedestal 106 is shown in FIGS. 2, 3 and 5. The pedestal 106 prevents the blockage of the first flow path L1 by keeping the flow path cylinder 102 away from the bottom surface 101a of the flange 101. The pedestal 106 is placed on the housing 105. The pedestal 106 has a cylindrical shape along the vertical direction, and includes a plurality of leg portions 106a along the circumferential direction. The pedestal 106 includes a plurality of protruding portions 106b protruding along the outer side in the radial direction at the lower end along the circumferential direction. The plurality of protruding portions 106b serve as a lower limit for the opening direction of the opening / closing portion 104P of the valve member 104.

  The eye plate 107 is shown in FIG. The eye plate 107 discharges the washing water and drainage W collected in the waterproof pan 600 between the channel cylinder 102 and the sealing cylinder 103. The eye plate 107 is formed in a disk shape and has a plurality of through grooves. The eye plate 107 discharges washing water, drainage W, and the like between the channel cylinder 102 and the sealing cylinder 103 through the through groove. The upper end portion 102 a of the flow channel cylinder 102 and the other end portion 108 b of the drainage joint 108 are inserted into a circular through hole opened in the center of the eye plate 107.

  The drainage joint 108 is shown in FIG. The drainage joint 108 causes the flow path cylinder 102 to discharge the drainage W discharged from the drainage hose of the washing machine 500. The drainage joint 108 has a cylindrical shape and is formed by bending a central portion into an L shape. A drain hose of the washing machine 500 is inserted into one end portion 108a of the drain joint 108. The other end portion 108 b of the drainage joint 108 is inserted into the eye plate 107 and is inserted into the flow channel cylinder 102.

  Next, the use state of the drain trap 100 will be described with reference to FIG.

  FIG. 6 is a schematic diagram showing a use state of the drain trap 100. FIG. 6A shows a state where the waste water W generated in the washing process or the rinsing process of the washing machine 500 is discharged through the storage portion 101 d of the basket 101. FIG. 6B shows a state where the waste water W of the storage unit 101d is discharged by the air generated in the drying process after the rinsing process of the washing machine 500. FIG. 6C shows a state in which the waste water W collected in the second flow path L2 is discharged to the storage unit 101d when all the steps of the washing machine 500 are completed.

  As shown in FIG. 6A, the waste water W generated in the washing process or the rinsing process of the washing machine 500 (not shown) flows from the first flow path L1 of the drain trap 100 through the storage portion 101d to the third flow. It is discharged toward the flow path L3. That is, the drainage W passes through the outlet 104 a of the valve member 104 from the channel cylinder 102, and is a space from the lower part of the ridge 101 to the outside of the sealing cylinder 103 (radially outward) and the inside of the ridge 101 (radially inward). After passing through, it is drained to a drain pipe (not shown). At this time, the opening / closing part 104P of the valve member 104 is moved from the open position OP to the closed position CL by the water pressure P from the waste water W discharged from the first flow path L1 to the third flow path L3, and the region R Is sealed. When the waste water W passes through the flow path cylinder 102 and the discharge port 104a of the valve member and is discharged to the bottom surface 101a of the trough 101, the direction of the water flow changes, so that the water pressure increases. Therefore, when the drainage water W is discharged from the first flow path L1 toward the third flow path L3, the valve member 104 causes the drainage W to flow backward toward the second flow path L2 into the region. It can be sealed at the R portion.

  A recent drum type washing machine includes a washing machine 500 of a type that exhausts hot air (air B) into a drainage hose of the washing machine 500 in a drying process performed after the dehydration process.

  As shown in FIG. 6B, when the washing machine 500 as described above is used, the sealed water in the basket 101 flows out to the drain pipe due to the wind pressure from the exhausted air B. If there is no sealed water that shuts off the air, the odor in the drain pipe leaks into the room. The waste water W stored between the flow channel cylinder 102 and the sealed water cylinder 103 remains in the drain trap 100.

  Further, as shown in FIG. 6C, when the entire process of the washing machine 500 is completed, the opening / closing portion 104P of the valve member 104 is not subjected to the water pressure from the drainage W or the wind pressure from the air. The region R is released by moving so as to naturally fall from the position CL to the open position OP. As a result, the waste water W stored between the channel cylinder 102 and the sealed cylinder 103 is discharged to the storage unit 101d and blocks the region R, so that odor passes from the third channel L3 to the region R. Thus, it is possible to prevent leakage to the indoor side toward the second flow path L2.

  According to embodiment mentioned above, there exists an effect by the following structures.

  The drain trap 100 includes a basket 101 having a storage portion 101d that stores the waste water W discharged from the washing machine 500 and discharges it to the outside, and a flow path cylinder that discharges the waste water W from the washing machine 500 toward the storage portion 101d. 102, a sealing cylinder 103 that is disposed radially outward of the flow path cylinder 102 and discharges the waste water W leaked from the washing machine 500 from the space between the flow path cylinder 102 toward the storage portion 101d, and the flow path cylinder And a valve member 104 that opens and closes the region R between the sealing tube 103 and the sealing tube 103, and the valve member 104 moves so as to approach and separate from the region R to open and close the region R. And a deformation part 104 that guides the movement of the opening / closing part 104P while being deformed by the opening / closing part 104P that is connected to the opening / closing part 104P and moves by the water pressure from the drainage W discharged from the flow channel cylinder 102 to the jar 101. And, with.

  The valve member 104 is used for the drain trap 100 and opens and closes the region R between the flow channel tube 102 and the sealing tube 103 and moves so as to approach and separate from the region R to open and close the region R. The open / close portion 104P is connected to the open / close portion 104P, and the open / close portion 104P is moved while being deformed by the open / close portion 104P that is moved by the water pressure from the drainage water W discharged from the flow channel cylinder 102 to the trough 101, and the open / close portion 104P is moved. And a deforming portion 104Q for guiding.

  The flow path unit 110 is used for the drain trap 100, and discharges the waste water W from the washing machine 500 toward the storage portion 101d, and a region between the flow path cylinder 102 and the sealing cylinder 103. Open / close R, move so as to approach and separate from region R, and open / close unit 104P that can freely open and close region R, and drainage W that is connected to open / close unit 104P and is discharged from channel cylinder 102 to bottle 101 The valve member 104 includes a deforming portion 104Q that guides the movement of the opening and closing portion 104P while being deformed by the opening and closing portion 104P that is moved by the water pressure.

  The drain trap 100, the valve member 104, and the flow path unit 110 configured as described above are disposed between the flow path cylinder 102 and the sealing cylinder 103 when the drainage W is discharged from the flow path cylinder 102 toward the trough 101. Region R is closed by valve member 104. Therefore, in the drain trap 100, the valve member 104, and the flow path unit 110, the waste water W discharged from the washing machine 500 through the flow path cylinder 102 flows back from between the flow path cylinder 102 and the sealing cylinder 103. Can be prevented.

  Furthermore, the opening / closing part 104P is provided with a discharge port 104a for discharging the waste water W from the channel cylinder 102 to the trough 101, and the deforming part 104Q is connected in an annular shape along the outer peripheral edge of the discharge port 104a, and radially outward. Curved towards.

  According to such a configuration, the opening / closing part 104P is closed from the open position OP by easily deforming the deforming part 104Q without obstructing the flow of the drainage W through the flow channel cylinder 102 by the discharge port 104a of the opening / closing part 104P. It can be quickly moved to the position CL.

  Further, the deformable portion 104Q is connected to the lower end portion 102b of the flow path tube 102.

  According to such a configuration, the valve member 104 can be disposed so as to be suspended from the flow channel cylinder 102 provided in the drain trap 100 without providing a special fixing member.

  Moreover, according to such a structure, the valve member 104 and the flow path cylinder 102 are integrally configured (flow path unit 110), so that they can be used in place of the existing drain trap structural members.

  Furthermore, the opening / closing part 104P includes a side wall 104b that extends radially outward from the sealing cylinder 103 and projects annularly upward from the outer peripheral edge thereof.

  According to such a configuration, since the drainage W can be stored inward in the radial direction of the side wall 104b, the drainage W stored in the storage unit 101d can be stored even when the opening / closing unit 104P is located at the open position OP. The drainage W blocks the region R without depending on the amount, and it is possible to prevent the odor from leaking from the sealed water tube 103 to the indoor side.

  Furthermore, the opening / closing part 104 </ b> P is moved by the wind pressure from the air B exhausted from the washing machine 500 and discharged from the flow path cylinder 102 to the basket 101.

  According to such a configuration, it is possible to prevent the waste water W stored between the flow path tube 102 and the sealed water tube 103 from being discharged. This drainage W functions as sealing water after being discharged into the tub 101. That is, when the entire process of the washing machine 500 is completed, the opening / closing part 104P of the valve member 104 does not receive the water pressure from the waste water W or the wind pressure from the air, and thus opens the region R. As a result, the waste water W stored between the channel cylinder 102 and the sealed cylinder 103 is discharged to the storage unit 101d and blocks the region R, so that odor passes from the third channel L3 to the region R. Thus, it is possible to prevent leakage to the indoor side toward the second flow path L2.

  Furthermore, the deforming part 104Q is formed integrally with the opening / closing part 104P.

  According to such a configuration, the valve member 104 can be manufactured at a lower cost by molding using a mold or the like than when the deformable portion 104Q and the opening / closing portion 104P are molded separately and bonded to each other. . Further, the valve member 104 has a stronger bonding state between the deformable portion 104Q and the opening / closing portion 104P than when the deformable portion 104Q and the opening / closing portion 104P are bonded to each other. Breakage and damage of the joint portion of the opening / closing part 104P can be suppressed.

(Other embodiments)
FIG. 7 is a cross-sectional view showing a drain trap 200 according to another embodiment. In addition, about the member same as the drain trap 100 of 1st Embodiment, the same code | symbol is used and the description is partially omitted.

  The drain trap 200 according to another embodiment is different from the drain trap 100 according to the first embodiment described above in that it includes a support member 209 that supports the opening / closing part 104P of the valve member 104 from below.

  The drain trap 200 includes a support member 209 that supports the opening / closing portion 104P of the valve member 104 from below. The support member 209 supports the opening / closing part 104P while moving together with the opening / closing part 104P of the valve member 104 by the water pressure P from the waste water W and the wind pressure from the air B. The support member 209 is bonded or in contact below the valve member 104. The support member 209 is made of plastics or the like harder than the valve member 104, and is formed in a disk shape having an opening 209a therein. The support member 209 includes an opening 209a having the same shape as the discharge port 104a of the valve member 104, and discharges the waste water W from above to below. The support member 209 rises when the water pressure P from the drainage W is applied to the bottom surface 209b. As a result, the support member 209 moves the opening / closing part 104P upward. The support member 209 descends when the water pressure P from the drainage W weakens or stops. As a result, the support member 209 moves the opening / closing part 104P downward.

  In other embodiments, the support member 209 has been described as a separate member from the valve member 104, but may be configured to be joined to the valve member 104 or formed integrally with the valve member 104.

  According to the drain trap 200 concerning other embodiment mentioned above, there exists an effect by the following composition.

  In the drain trap 200, the valve member 104 includes a support portion (support member 209) that supports the opening / closing portion 104P from below.

  According to such a configuration, the valve member 104 supported by the support member 209 can sufficiently seal the region R.

  Further, according to such a configuration, the support member 209 is useful when the valve member 104 is made of rubber or the like in which the opening / closing portion 104P and the deformation portion 104Q are integrally formed and is easily deformed as a whole. is there. Since it is desirable that the deformable portion 104Q be easily deformed while the openable / closable portion 104P is maintained, the support member 209 can ensure the regularity of the openable / closable portion 104P.
