Description

  The present invention relates to a drainage structure in which drainage from a hand-washer can be discharged using a drainage channel for a toilet device.

  Conventionally, as a drainage structure of a sanitary device, for example, Patent Document 1 discloses a drainage structure that allows drainage of a hand-washer and drainage from a toilet bowl in a toilet device to be discharged through a common drainage channel. .

  In this conventional drainage structure, the downstream end of the hand-washer drainage conduit that allows the wastewater from the hand-washer to flow is connected to the toilet drainage that guides the wastewater to the drainage channel outside the toilet device provided in the toilet device. Therefore, the waste water from the hand-washing device is discharged to the drainage channel outside the toilet device through the hand-washing device drain line and the toilet drainage part provided in the toilet device.

  In the above-mentioned conventional example, it is only necessary to form a single drainage channel dedicated to the toilet device on the building side by flowing the wastewater of the hand-washer to the toilet drainage part provided in the toilet device, and the construction can be simplified. In renovation, toilets and hand-washers can be drained using the same single drainage channel for toilets as it is, so a drainage channel for hand-washers that is different from the drainage channel for toilets is formed on site. Therefore, it is possible to newly install a hand-washing device without performing a large-scale construction when the toilet device is reformed.

  However, in the above-described conventional example, the downstream end of the hand-washer drainage pipe for flowing the drainage of the hand-washer, the toilet drainage part for discharging the wastewater from the toilet bowl part to the drainage channel outside the toilet device There are the following problems because it is connected in communication.

  In other words, when water (dirt water) collected in the toilet bowl part of the toilet device is poured into the toilet drain part at once, the water that has flowed from the toilet bowl part temporarily connects the toilet drain line in the toilet drain part. In this case, the water in the handwasher drainage pipe is partially filled with water, and a part of the drainage flows backward from the downstream end to the handwasher drainage pipe, thereby increasing the pressure in the handwasher drainage pipe. The seal water may be pushed up, and the seal water in the seal trap part may flow back into the hand-washer bowl part.

  The present invention has been made in view of the above-described conventional problems, and in which drainage of a hand-washer is drained to the outside of the toilet device via the toilet drainage part of the toilet device, the structure is simple. It aims at providing the drainage structure which can prevent the sealing water in the sealing water trap part of a hand-washer drain pipe flowing backward to the hand-washer side.

  In order to solve the above problems, the present invention has the following configuration.

  The drainage structure of the present invention comprises a toilet bowl 2 and a toilet bowl 6 and a toilet drain 13 for discharging drainage from the toilet bowl 6 to the drainage channel 3 outside the toilet 2. The downstream end of the hand-washer drain line 28 through which the waste water 1 flows is connected to the toilet drain 13 and a sealed trap part 31 is formed in the middle of the hand-washer drain line 28. The enormous tube portion 5 having an inner diameter larger than that of the sealed water trap portion 31 is provided on the handwasher 1 side of the 28 sealed water trap portions 31.

  By having such a configuration, when the water accumulated in the toilet bowl portion 6 is drained at once and flows into the toilet drainage portion 13, the water that has flowed at once is temporarily a drainage pipe in the toilet drainage portion 13. The passage 28 is filled with water at the connecting portion, and a part of the drainage flows back to the hand-washer drain pipe 28 from the downstream end, the pressure in the hand-washer drain pipe 28 rises, and the hand-washer drain pipe Even if a phenomenon occurs in which the sealed water in the 28 sealed water trap portions 31 is pushed up, it is possible to prevent the pushed-up sealed water from flowing into the enormous tube portion 5 and flowing back to the hand-washer 1.

  Further, the toilet drainage unit 13 includes a turn trap device 15 and a flowing water direction changing unit 20 that receives the drainage discharged from the turn trap device 15 and converts the drainage into a lateral flow and flows it downstream. The device 15 is a bendable trap cylinder 18 connected to the toilet bowl section 6, and the trap cylinder 18 is bent so that the trap cylinder 18 is stored in the toilet bowl section 6 in a sealed state and the toilet bowl section. It is preferable that the end of the handwasher drain line 28 is connected to the flow direction changing unit 20 in communication with the drainage state in which the water stored in the drainage can be switched.

  The toilet apparatus 2 of the type in which the trap cylinder 18 is reversed and the water accumulated in the toilet bowl unit 6 is flowed to the flow direction changing unit 20 at a stretch to be changed to a horizontal flow and flows to the downstream side is changed. Since the flow is changed in the horizontal direction in the section 20, the flow direction changing section 20 has a structure that tends to be temporarily filled with water. When the downstream end of the hand-washer drain pipe 28 is connected to the flowing water direction changing unit 20 which is likely to be temporarily filled with water, the pressure when the water flowing direction changing unit 20 is temporarily filled with water. A phenomenon in which the sealed water in the sealed water trap portion 31 is pushed up by the rising and flows backward easily occurs. However, according to the present invention, it is possible to prevent the pushed-up sealed water from flowing into the enormous tube portion 5 and backflowing into the hand-washing device 1, so that the waste water from the turn trap device 15 can be turned sideways in the flowing water direction changing portion 20. Even if it has a structure that changes the flow, even if the downstream end of the hand-washer drain pipe 28 is connected to the flowing water direction changing unit 20, there is no possibility of backflow of the sealed water.

  Since the present invention is configured as described above, a sealing trap part is formed in the middle of the hand-washer drain pipe, and the hand-washer side of the hand-washer drain pipe is closer to the hand-washer than the seal trap part. However, when the water that has accumulated in the toilet bowl is drained at once and then flows into the toilet drain, the water that has flowed at a time is temporarily washed in the toilet drain. Even if the drainage pipe line is filled with water at the connecting part and the pressure in the handwasher drainage pipe rises, the sealed water can flow into the enormous pipe part and can be prevented from flowing back into the handwasher. .

It is principal part sectional drawing which shows an example of embodiment of this invention. It is a disassembled perspective view which shows the pipe line structure of a drainage structure same as the above. It is a front view which shows an example of the enormous pipe part provided in the hand-washer drain pipe of the hand-washing machine of the drainage structure same as the above.

  Hereinafter, the present invention will be described with reference to the accompanying drawings. In the drainage structure of the present embodiment shown in FIGS. 1 to 3, the drainage of the hand-washing machine 1 and the toilet device 2 installed at positions separated in the same toilet room is discharged through a common drainage channel 3. It has become.

  The toilet device 2 is a toilet-shaped toilet body 7 having a toilet bowl portion 6 provided with a toilet seat, a toilet lid, and the like, and is used as a Western flush toilet.

  In addition to the toilet bowl part 6, the toilet bowl body 7 includes a rim part 10 provided on the toilet bowl part 6, and a skirt part 11 that forms the outer surface part of the toilet bowl body 7 and covers the outside of the toilet bowl part 6. And a drain cylinder 12 projecting rearward is formed at the lower end of the toilet bowl 6.

  The water stored in the toilet bowl 6 can be discharged to the drainage channel 3 outside the toilet device 2 through the toilet drainage 13 provided in the toilet device 2, and the toilet drainage 13 of this embodiment is The turn trap device 15 and the drainage adapter device 16 are provided in the toilet bowl outer body 7. The toilet shell 7 is also equipped with a cleaning liquid discharge device, a local cleaning device, and the like that supply cleaning liquid into the toilet bowl portion 6 as other accessory devices.

  The turn trap device 15 includes a trap case 17 provided behind the toilet bowl portion 6, a flexible trap cylinder 18 provided in the trap case 17, and a motor as a drive source for bending the trap cylinder 18. ing. One end of the trap cylinder 18 is connected to the rear part of the drain cylinder 12 and the other end is a free end.

  The trap cylinder 18 is bent by driving the motor, whereby a trap state is formed with the end opening 19 on the free end side facing upward, and the trap opening 18 is facing downward as shown in FIG. It can be switched to the drained state with the structure released.

  The trap cylinder 18 is in a sealed state when not in use, and the end opening 19 of the trap cylinder 18 is arranged higher than the drain cylinder 12 so that water is accumulated in the toilet bowl 6, and the trap cylinder 18 Water accumulates inside and is sealed. After the stool, the trap cylinder 18 is drained, and the water stored in the toilet bowl 6 is discharged to the drainage adapter device 16 below through the drain cylinder 12 and the trap cylinder 18.

  The drainage adapter device 16 guides the water discharged from the trap cylinder 18 to the upstream end of the drainage channel 3 provided at a position shifted forward from the end opening 19 of the trap cylinder 18. The device 16 is used when the toilet device 2 is installed using the existing drainage channel 3 by reforming.

  The drainage adapter device 16 includes a flowing water direction changing unit 20 installed on the floor 21 below the trap case 17 and a discharge pipe installed on the floor 21 below the toilet bowl unit 6 and positioned in front of the flowing water direction changing unit 20. It is comprised by the part 22 and the connection pipe part 23 which connects both.

  The flowing water direction changing unit 20 is composed of a curved pipe having an upstream end opened upward and a downstream end opened forward and bent at a substantially right angle, and the water discharged from the trap cylinder 18 is at the bottom of the flowing water direction changing unit 20. After being received once, it turns to the front and flows downstream.

  The connecting pipe portion 23 is a straight pipe, and the rear end portion, which is the upstream end portion, is connected to the downstream end portion of the flowing water direction changing portion 20, and the front end portion, which is the downstream end portion, is upstream of the discharge pipe portion 22. The water discharged from the flowing water direction changing part 20 is connected to the side end part and flows to the discharge pipe part 22.

  The discharge pipe portion 22 is composed of a curved pipe having an upstream end opened rearward and a downstream end opened downward and bent substantially at a right angle. The downstream end of the discharge pipe portion 22 is connected to the upstream end of the drainage channel 3 protruding on the floor 21, and the water discharged from the flowing water direction changing unit 20 is discharged to the drainage channel 3.

  On the other hand, the handwasher 1 includes a handwasher bowl portion 25 and a water supply device 26 for supplying water to the handwasher bowl portion 25 at the top.

  A hand-washer drain port 27 is provided at the bottom of the hand-washer bowl 25. The hand-washer drain port 27 is connected to the flowing water direction changing part 20 of the drainage adapter device 16 through the hand-washer drain line 28. Specifically, the downstream end portion of the hand-washer drain pipe 28 is connected to a connection cylinder portion 30 protruding rearward from the rear wall portion 29 of the flowing water direction changing portion 20. As a result, the water in the hand-washer bowl portion 25 is discharged from the hand-washer drain port portion 27 through the hand-washer drain port portion 27 and the hand-washer drain conduit 28 into the flowing water direction changing portion 20, and thereafter the toilet bowl portion 6 In the same manner as the drainage from, it is discharged to the drainage channel 3 through the connection pipe part 23 and the discharge pipe part 22 in order. A water-sealing trap part 31 consisting of a pipe part bent in a substantially U-shape is provided in the upstream part of the hand-washer drain pipe 28, and sealing is performed by the water sealed in the water-seal trap part 31.

  Here, the flowing water direction changing unit 20 is located in the rear part of the toilet device 2, and the downstream end of the hand washing machine drain pipe 28 is connected to the flowing water direction changing unit 20 as described above. 28 is located at the rear of the toilet device 2, and when viewed from the front side of the toilet device 2, the hand-washer drain line 28 is not conspicuous, and the hand-washer drain tube is used when the toilet device 2 is used. Road 28 does not get in the way.

  The enormous pipe portion 5 having an inner diameter larger than that of the sealed water trap portion 31 is provided closer to the hand wash device 1 than the sealed water trap portion 31 of the handwasher drain pipe 28.

  In order to drain the water accumulated in the toilet bowl 6, the motor provided in the turn trap device 15 is driven as described above, and the trap cylinder 18 is rotated so that the end opening 19 faces downward. From the end opening 19 that has turned downward, it is discharged to the flowing water direction changing portion 20 immediately below the end opening 19, and the water flowing down from above is received by the flowing water direction changing portion 20 and changed into a horizontal flow, and the connecting pipe portion 23. Then, it is discharged to the drainage channel 3 outside the toilet device 2 through the discharge pipe part 22.

  In this case, when the motor is driven and the trap tube 18 is rotated so that the end opening 19 faces downward, the water accumulated in the toilet bowl portion 6 changes the direction of flowing water immediately below the end opening 19. Since the water that has flowed into the unit 20 at a stretch and the water that has flowed in at a stroke changes its flow in the lateral direction within the flow direction change unit 20, the flow direction conversion unit 20 is likely to be temporarily filled with water.

  When the water accumulated in the toilet bowl part 6 flows into the flowing water direction changing part 20 at once, water flows into the hand-washer drain pipe 28 connected to the flowing water direction changing part 20 from the communicating connection part. The pressure in the handwasher drain line 28 rises, and the sealed water in the water trap part 31 of the handwasher drain line 28 is pushed up and flows back to the handwasher 1 side.

  However, in the present invention, as described above, the enormous pipe portion 5 having an inner diameter larger than that of the sealed water trap portion 31 is provided on the side of the hand wash basin 1 than the sealed water trap portion 31 of the handwasher drain pipe 28. Therefore, the sealed water that is pushed upward and flows backward flows into the enormous tube portion 5, lowers the backflow height, and can relieve the backflow to the hand-washer bowl portion 25.

  In this manner, the downstream end of the hand-washer drain pipe 28 is connected to the flowing water direction changing portion 20, which is a portion where the trap tube 18 flows from the end opening 19 at a stretch and becomes temporarily full and the pressure rises. Since the backflow of the sealed water trap portion 31 of the hand-washer drain line 28 to the sealed hand-washer 1 can be alleviated even if it is connected, the hand-washer drain pipe 28 is not noticeable and obstructive as described above. There is no problem even if it is configured to connect the hand-washer drainage pipe line 28 to the flowing water direction changing part 20 at the rear part in the toilet device 2 so as not to become a problem.

  In addition, although the flowing direction change part 20 of the said this embodiment changes the direction of the waste_water | drain from the turn trap apparatus 15 to the front, you may change into the horizontal flow of directions other than the front.

  Moreover, in the said embodiment, although the drainage adapter apparatus 16 was comprised by the flowing water direction conversion part 20, the connection pipe part 23, and the discharge pipe part 22 which became a different body, this drainage adapter apparatus 16 is the pipe | tube formed integrally. It may be constituted by. Further, in the present embodiment, the toilet drainage unit 13 is described as an example of a so-called turn trap system provided with the turn trap device 15, but the toilet drainage unit 13 is not limited to this, and the toilet drainage unit 13 is As long as the toilet bowl 6 and the drainage channel 3 are communicated to lead the water to the drainage channel 3 in the toilet bowl 6, other configurations, for example, the toilet drainage 13 can be siphoned or washed away. There may be.
