Description

  The present invention is, for example, a drain pipe for draining water from household appliances such as a kitchen sink and a wash basin installed in each dwelling of an apartment house, each floor of an office building, or a detached house. The present invention relates to a cleaning facility suitable for cleaning.

In recent years, in apartment houses such as apartments, the kitchen sink drainage of each household is separated from other domestic wastewater, and a dedicated kitchen sink drainage horizontal pipe 101 and a kitchen sink drainage pipe 103 are used as shown in FIG. It tends to drain. This is because the kitchen sink wastewater contains oils and fats in foods, and is therefore more easily clogged than other domestic wastewaters due to the effects of the oils and fats. In particular, the kitchen sink drainage horizontal branch pipe 101 is likely to be clogged because the drainage flow is weak. For example, the kitchen sink drainage side branch pipe 101 needs to be cleaned at a cycle of about twice a year. In addition, when the sink 20 with a disposer is provided, the washing | cleaning period of the kitchen sink drainage side branch pipe 101 becomes still shorter. For this reason, the pipe material to which an oil-fat etc. cannot adhere easily is calculated | required.
Cleaning of the kitchen sink drainage horizontal branch pipe 101 is generally performed by the cleaning operator according to the following procedure. First, a strainer and a trapezoidal cover (not shown) in the drain trap 27 referred to as a so-called one trap shown in FIG. 7 are removed from the sink 20 side. Next, a high-pressure hose with a cleaning nozzle is inserted into the kitchen sink drainage branch pipe 101 through the connecting pipe 23 from the tip of the water tank raised from the sink 20 side center to the bottom of the drain trap 27. Is done. In this state, cleaning water is jetted from the cleaning nozzle, and the high pressure hose with the cleaning nozzle is pushed into the kitchen sink drainage branch pipe 101, whereby the kitchen sink drainage branch pipe 101 is cleaned. Here, there is a tendency that the moss collected at the bottom of the one-trap reservoir will bounce off when cleaned with a cleaning nozzle.

One end (the inflow leg side) of the drain trap 24 is connected, and the drain trap 24 is connected to a connecting pipe 26 on the back side of the sink 20 via an elbow 25 or the like, for example. Furthermore, the lower end part of the connecting pipe 26 is connected to the upstream end of the kitchen sink drainage horizontal branch pipe 30 through an elbow 25 or the like, for example. The kitchen sink drainage horizontal branch pipe 30 is slightly inclined so that the downstream side is lowered, and its downstream end is connected to the kitchen sink drainage pipe 34 via the pipe joint 32.

The kitchen sink drainage pipe 34 is a vertical pipe for guiding the kitchen wastewater flowing in from the kitchen sink drainage side branch pipe 30 of each floor to a wastewater treatment tank (not shown) through the horizontal drainage main pipe. It is installed in a dedicated section in the apartment house. For this reason, the pipe length of the kitchen sink drainage horizontal branch pipe 30 is generally set to 2 m to 3 m. In addition, the kitchen sink drainage pipe 34 is generally installed in the back side of the indoor decorative wall board.
With the above configuration, kitchen wastewater discharged from the sink 20 is, for example, a disposer (disposers have recently been widely used in high-rise apartments, etc.) 22, a drain trap 24, a connecting pipe 26, and a kitchen sink drainage branch. It flows into the kitchen sink / drain stack 34 through the pipe 30 and is guided to the waste water treatment tank or the like through the path by the kitchen sink / drain stack 34.
That is, the kitchen sink drainage branch pipe 30 corresponds to the drainage branch pipe of the present invention.
As mentioned above, the kitchen sink drainage contains the fats and oils of food, so that the fats and oils adhere to the inner wall surface of the pipe and narrow the inside of the pipe, and the microorganisms propagate and they become keratinized over time. Cause clogging. In particular, the kitchen sink drainage horizontal branch pipe 30 is likely to be clogged because the drainage flow is weak, and it is necessary to clean it regularly.
The drainage horizontal branch pipe cleaning facility 10 according to the present embodiment is a facility for efficiently cleaning the kitchen sink drainage horizontal branch pipe 30 and is configured as follows.

The drainage side branch pipe cleaning equipment 10 has a guide pipe 40 capable of guiding a hose 50 with a cleaning nozzle, which will be described later, to the kitchen drainage horizontal branch pipe 30, and a kitchen sink drainage of the hose 50 with a cleaning nozzle through the guide pipe 40. The feeding device 60 is configured to feed the side branch pipe 30.
The guide pipe 40 is a pipe through which the hose 50 with a cleaning nozzle can pass, and for example, as shown in FIG. 3, the bottom plate (not shown) of the sink 20 from the front side of the sink 20 to the position of the connecting pipe 26 on the back side. Is not laid). The leading end of the guide pipe 40 is connected to the connecting pipe 26 via a T-shaped joint 44.
The guide pipe 40 has an inner diameter dimension and a curvature of a bent portion in accordance with the hose 50 with a cleaning nozzle so that the hose 50 with a cleaning nozzle can be smoothly passed through, and further gently so that the tip side is slightly lower. An inclined surface is provided.
As shown in FIG. 3 or the like, the T-shaped joint 44 (generally also referred to as “TY”) includes a body portion 44b, and an upper receiving port 44u and a lower receiving port 44d are provided at the upper end and the lower end of the body portion 44b, respectively. Is formed. Further, a lateral tube 44y inclined upward is provided on the side surface of the body portion 44b, and a lateral receiving port 44s is formed in a state of being laterally bent at the distal end of the lateral tube 44y.
An upper pipe 26u of the connecting pipe 26 is connected to the upper receiving port 44u of the T-shaped joint 44, and a lower pipe 26d of the connecting pipe 26 is connected to the lower receiving port 44d. Further, the distal end of the guide pipe 40 is connected to the horizontal receiving port 44 s of the T-shaped joint 44.

With the above configuration, the hose 50 with the cleaning nozzle guided to the position of the T-shaped joint 44 by the guide pipe 40 is inserted into the connecting pipe 26 from the oblique direction by the horizontal pipe 44 y of the T-shaped joint 44. Here, the curvature of the horizontal pipe 44y of the T-shaped joint 44 with respect to the guide pipe 40 is set to a value that allows the hose 50 with the cleaning nozzle to pass easily. For this reason, the hose 50 with the cleaning nozzle can be smoothly inserted into the connecting pipe 26 from the guide pipe 40. In addition, since the elbow 25 etc. which has a predetermined curvature radius are provided between the connection pipe 26 and the kitchen sink drainage horizontal branch pipe 30, the hose 50 with a washing nozzle is connected to the kitchen from the connection pipe 26 by the elbow 25. The drainage horizontal branch pipe 30 is smoothly guided.
A receiving port 42 (see FIG. 1) is formed at the base end portion of the guide pipe 40, and a connecting tube 62c provided in the housing 62 of the feeding device 60 is inserted and fixed to the receiving port 42. As a result, the base end portion of the guide pipe 40 is fixed to the position of the connection pipe 62 c of the housing 62 of the feeding device 60.
That is, the connecting pipe 62c of the housing 62 corresponds to a fixing means for fixing the base end portion of the guide pipe according to the present invention, and the guide pipe 40 and the horizontal pipe 44y of the T-shaped joint 44 correspond to the guide pipe of the present invention. .
As shown in FIG. 2C, the hose with a cleaning nozzle 50 includes a high-pressure hose 52 and a cleaning nozzle 54 attached to the tip of the high-pressure hose 52. The high-pressure hose 52 is a hose having an inner diameter of about 4 mm to 9 mm. Is set. As the high-pressure hose 52, a high-pressure hose having rigidity that does not bend the distal end side or midway when being pushed into the pipe is used. For the high-pressure hose 52, for example, a resin-made flexible hose or a metal-made flexible hose is used.

The cleaning nozzle 54 is a forward injection type nozzle, and a central injection port 54m is formed at the center of the tip. A plurality of peripheral injection ports 54r are radially formed behind the central injection port 54m in a state of being directed obliquely forward. As a result, clogging components that block the center of the kitchen sink drainage branch pipe 30 are pressed and removed by the washing water sprayed from the central injection port 54m, and clogging components adhering to the inner wall surface of the kitchen sink drainage branch pipe 30 are peripherally injected. It can be removed by the washing water sprayed from the port 54r.
The feeding device 60 is a device that feeds the hose 50 with the cleaning nozzle from the downstream end of the kitchen drainage horizontal branch pipe 30 to the standing pipe through the guide pipe 40, the T-shaped joint 44, and the lower pipe 26 d of the connecting pipe 26.
The feeding device 60 includes a drum 64 that can wind up the hose 50 with a cleaning nozzle, a housing 62 that houses the hose 50 with the cleaning nozzle and the drum 64, and an operation handle 66 (rotating means) that rotates the drum 64 from the outside of the housing 62. ) .
The drum 64 includes a central shaft 64p (see FIG. 1), and the central shaft 64p is rotatably supported by a bearing (not shown) of the housing 62. An operation handle 66 (see FIG. 2A) is connected to one end of the central shaft 64p protruding outside the housing 62. Further, as shown in FIG. 1, a rotatable connector 65c is attached to the other end of the center shaft 64p protruding outside the housing 62, and the water supply pipe 65 and the hose with the cleaning nozzle are connected via the connector 65c. 50 high-pressure hoses 52 are connected. Further, the water supply pipe 65 is connected to a water pipe (not shown) through a valve 65v.

The housing 62 is a hermetically sealed container that covers the periphery of the drum 64, and as shown in FIG. The housing 62 is provided with stays 62s (see FIG. 2A) at the lower four positions (front and rear, left and right), and these stays 62s are bolted to the bottom plate (not shown) of the sink 20. It should be noted that a vibration-proof rubber 62b (see FIG. 2B) is sandwiched between the stay 62s and the bottom plate of the sink 20 at the time of bolting.
As shown in FIG. 2A, a connection pipe 62 c that is inserted into the receiving port 42 of the guide pipe 40 is formed in the lower right center of the housing 62. The connecting pipe 62c is provided with a stopper (not shown) so that the cleaning nozzle 54 attached to the tip of the hose 50 with the cleaning nozzle does not enter the inside of the housing 62 when the hose 50 with the cleaning nozzle is wound around the drum 64. It has been.
The guide pipe 40 can be directly connected to the connection pipe 62c, and a flexible auxiliary guide pipe 55 can be connected as shown by a two-dot chain line in FIG. The connecting pipe 62c can be connected to the guide pipe 40 via
Further, a connector 62x to which the internal cleaning hose of the housing is connected is attached to the ceiling portion of the housing 62. The housing 62 is configured to be removable on the front side so that it can be disassembled and cleaned.

Next, a procedure for cleaning the kitchen sink drainage horizontal branch pipe 30 using the drainage horizontal branch pipe cleaning equipment 10 according to the present embodiment will be described.
First, the drum 64 is rotated counterclockwise in FIG. 1 by the operation handle 66, and the hose 50 with the cleaning nozzle is sent along the guide pipe 40. Then, the valve 65v of the water supply pipe 65 is opened at the timing when the cleaning nozzle 54 located at the tip of the hose 50 with the cleaning nozzle reaches the vicinity of the T-shaped joint 44. As a result, the cleaning water is sprayed obliquely forward from the cleaning nozzle 54. In this state, the drum 64 is further rotated counterclockwise in the drawing, and the hose 50 with the cleaning nozzle is moved from the downstream end of the kitchen sink drainage horizontal branch pipe 30 to the vertical pipe from the guide pipe 40 through the T-shaped joint 44 and the communication pipe 26. Sent. As a result, the pipe is roughly cleaned from the lower pipe 26d of the communication pipe 26 to the kitchen drainage horizontal branch pipe 30. The timing for opening the valve 65v of the water supply pipe 65 may be before the drum 64 is rotated.
Next, the drum 64 is slowly rotated rightward in the drawing by the operation handle 66, and the hose 50 with the washing nozzle sent from the downstream end of the kitchen sink drainage side branch pipe 30 to the vertical pipe is slowly wound up. As a result, the washing nozzle 54 of the hose 50 with the washing nozzle slowly moves in the upstream direction from the downstream end of the kitchen sink drainage branch pipe 30, and the washing is sprayed radially forward (downstream direction) from the washing nozzle 54. Oils and fats attached to the inner wall surface of the kitchen sink drainage horizontal branch pipe 30 are washed away in turn from the downstream side. The oils and fats that have been washed off are flowed to the kitchen sink / drain stack 34 along with the cleaning water.
Then, when the cleaning nozzle 54 reaches the position of the connection pipe 62c of the housing 62, the cleaning is finished and the valve 65v of the water supply pipe 65 is closed.
Here, since the housing 62 is formed in a sealed container shape, there is no problem that the inside of the sink 20 is soiled even if a part of the washing water overflows from the guide pipe 40.
Moreover, the hose 50 with a cleaning nozzle can be cleaned by connecting a cleaning hose to the connector 62x of the housing 62 and pouring tap water (cleaning water) into the housing. The drainage in the housing 62 is caused to flow to the kitchen drainage horizontal branch pipe 30 through the guide pipe 40, the T-shaped joint 44, and the connecting pipe 26.

Here, according to the drainage side branch pipe cleaning equipment 10 according to the present embodiment, the kitchen sink drainage side branch pipe 30 is cleaned while spraying the cleaning water from the cleaning nozzle 54 diagonally forward (downstream direction) radially. In the kitchen sink drainage horizontal branch pipe 30, a strong airflow flowing from the upstream side to the downstream side is generated. For this reason, the sealed air in the drain trap 24 (see FIG. 3) is caused to flow downstream by the air flow, and the drain trap 24 is emptied after cleaning. Therefore, it is necessary to quickly open the faucet 21 of the sink 20 and replenish the drain trap 24 with sealed water after washing the kitchen sink drainage horizontal branch pipe 30.
As described above, according to the drainage side branch pipe cleaning equipment 10 according to the present embodiment, the hose 50 with the cleaning nozzle is inserted into the pipe from the base end side of the guide pipe 40 fixed to the front side of the sink 20. The hose 50 with the cleaning nozzle can be guided to the kitchen sink / drainage horizontal pipe 30 by the guide pipe 40. For this reason, the kitchen sink drainage horizontal branch pipe 30 can be cleaned without touching the sink 20, and the residents are not left unsanitary.
Further, the feeding device 60 further facilitates the feeding operation of the hose 50 with the cleaning nozzle, and improves the efficiency of the cleaning operation.
Furthermore, the feeding device 60 includes a drum 64 that can wind up the hose 50 with a cleaning nozzle, and a housing 62 that houses the drum 64 and the hose 50 with a cleaning nozzle. Because of the structure in which the drum 64 is rotated about its axis, the cleaning operation can be performed without dirtying hands. Therefore, it is possible for the resident to clean the kitchen sink and drainage horizontal pipe 30 by himself without relying on the cleaning operator.
Moreover, since the washing nozzle 54 attached to the hose 50 with the washing nozzle is configured to inject washing water obliquely forward, the clogging component of the pipe is washed with the washing water in the direction of the downstream side of the drainage horizontal branch pipe 30, That is, it can be pushed away in the direction of the kitchen sink / drain stack 34. For this reason, it becomes difficult for washing water to flow back to the base end side of the guide pipe 40.

Next, a procedure for cleaning the kitchen sink drainage side branch pipe 30 using the drainage side branch pipe cleaning equipment 70 according to the present embodiment will be described.
First, the lid provided at the base end portion 72m of the guide pipe 72 is opened. Next, the connecting pipe of the feeding device is connected to the base end portion 72m, and the hose 50 with the cleaning nozzle is fed into the drainage path through the guide pipe 72, and the kitchen sink drainage side branch pipe as described in the first embodiment below. Perform 30 washes.
As described above, the drainage horizontal branch pipe cleaning facility 70 according to the present embodiment can also perform the cleaning operation of the kitchen sink horizontal branch pipe 30 without touching the sink 20, and is unsanitary for residents. There is no feeling. In particular, according to the present embodiment, since the hose 50 with the cleaning nozzle can be inserted from the upstream side of the connection pipe 26, not only the kitchen sink drainage horizontal branch pipe 30 but also the drainage path including the connection pipe 26 can be cleaned.
In the present embodiment, the configuration in which the feeding device is connected to the base end portion 72m of the guide pipe 72 is illustrated, but this is omitted and the cleaning operator manually operates the hose 50 with the cleaning nozzle through the base end portion 72m. You can also send it in. In this case, since the lid on the base end portion 72m side of the guide pipe 72 is opened during cleaning, the outside air is guided even if a strong air current flowing from the upstream side to the downstream side is generated in the kitchen sink drainage side branch pipe 30. It is supplied to the kitchen sink drain side branch pipe 30 by the pipe 72. For this reason, the force of sucking the sealed water in the drain trap 24 to the downstream side is weakened, and the problem that the drain trap 24 is emptied after washing is less likely to occur.
Further, it is possible to push air from the base end portion 72m side of the guide pipe 72 by a blower during cleaning so that the sealed water in the drain trap 24 can be secured.

Furthermore, in the second embodiment, an example in which the guide pipe 72 is laid inside the sink 20 has been shown. However, as shown by an imaginary line (two-dot chain line) in FIG. It is also possible to fix the mortar M to the penetrating part KS of the vertical wall S that partitions the dedicated part P inside the apartment house and the shared part C outside the house. In this case, it is desirable that the base end portion 72m of the guide pipe 72 serving as a cleaning port is fixed near the upper end portion of the vertical wall S. The guide pipe 72 is laid in the horizontal direction along the back of the ceiling to the position above the sink 20 and then lowered at the position of the sink 20. In the range along the ceiling of the guide pipe 72, a gradient is given at an appropriate angle in the direction going down to the sink 20 side. Thereby, the backflow of the cleaning water to the cleaning port side can be prevented. Further, since the guide pipe 72 does not have a rising portion in the path from the base end portion 72m to the inside of the side branch pipe 30 with respect to the entering direction of the hose 50 with the cleaning nozzle, the hose 50 with the cleaning nozzle can smoothly enter. . Furthermore, since the base end portion 72m as the cleaning port is set at a high position near the upper end portion of the common portion C, mischief such as throwing of foreign matter into the cleaning port can be prevented in advance.
And the front-end | tip of the guide piping 72 is connected to the upper receiving port 78u of the T-shaped coupling 78. FIG. It is also possible to use a flexible pipe at an appropriate position in the middle of the guide pipe 72. Further, the guide pipe 72 may penetrate the vertical wall S at a horizontal level and be fixed to the vertical wall S with mortar or the like. As a result, the configuration on the side of the dedicated portion of the guide pipe 72 can be freely designed.
That is, the penetrating part KS and the mortar M correspond to the fixing means of the present invention.
Moreover, it is good also as a structure which fixes 72 m of base end parts of the guide piping 72 not to the said common part C but to the other site | part of the exclusive part P. FIG. For example, as shown by a two-dot chain line in FIG. The base end 72m is extended to the pipe shaft P. It is good also as a structure fixed to the wall part W which partitions off S. FIG. The base end portion 72m fixed to the wall W can be closed with the cleaning port lid H, and the cleaning port lid H can be removed during the cleaning operation, and the hose 50 with the cleaning nozzle can be inserted from the base end portion 72m. Further, as shown by a two-dot chain line in FIG. 5, the base end portion 72m of the guide pipe 72 may be fixed to the upper surface of the counter portion F to which the tap J of the water supply is attached. Also in this case, the base end portion 72m of the guide pipe 72 is closed with the cleaning port lid H, and the cleaning nozzle hose 50 can be inserted into the guide piping 72 by removing the cleaning port lid H during the cleaning operation. As described above, the portion for fixing the base end portion 72m of the guide pipe 72 can be arbitrarily set in consideration of the efficiency of the cleaning operation.

In this way, the base end portion 72m of the guide pipe 72 can be fixed to the penetrating portion KS of the vertical wall S that divides the dedicated portion P that is inside the apartment house and the shared portion C that is outside the residence by the fixing means. It becomes possible to insert the hose 50 with the cleaning nozzle into the guide pipe 72 from the shared part C which is outside. Therefore, it is possible to clean the kitchen sink drainage branch pipe 30 in the house from outside the house, and it is possible to secure the sealed water of the drain trap 24.
In this embodiment, the cleaning equipment for the kitchen sink drainage horizontal branch pipe 30 in the sink 20 provided with the disposer 22 has been described. However, as shown in FIG. 6, a drain trap 27 called a so-called one trap with a strainer. It is also possible to apply the present invention to the washing equipment for the kitchen sink drainage side branch pipe 30 in the sink 20 equipped with the above.
In the case of the sink 20 including the drain trap 27, a Y-shaped joint 78 is provided in the middle of the connecting pipe 26 that connects the drain trap 27 and the elbow 25, and the tip of the guide pipe 72 is connected to the connecting pipe using the Y-shaped joint 78. 26 is connected obliquely from above. As described above, the base end portion 72m of the guide pipe 72 is fixed to the through portion KS of the vertical wall S that divides the dedicated portion P and the shared portion C by a fixing means. As a result, the kitchen sink drainage horizontal branch pipe 30 in the house can be cleaned from outside the house.
In the first embodiment and the second embodiment, the description has been given by taking as an example the equipment for cleaning the kitchen sink drainage branch pipe 30; however, the kitchen sink drainage branch pipe 30 by the drainage branch pipe cleaning equipment according to the present invention. It is also possible to clean the drainage horizontal branch pipe other than the above.

Next, a third embodiment of the present invention will be described. In the first and second embodiments, the guide pipes 40 and 72 are provided in the connecting pipe that connects the drain trap 24 and the drainage horizontal branch pipe 30, and the hose with the cleaning nozzle is installed in the pipe through the guide pipes 40 and 70. It was configured to be inserted and washed. This Embodiment 3 is different from Embodiments 1 and 2 in that a guide pipe 84 for inserting a hose with a cleaning nozzle is provided in the appliance drain pipe 82 of the drain trap 80 as shown in FIG. Yes.
As shown in FIG. 8, the drain trap 80 in this embodiment includes a U-shaped trap body 81 and an instrument drain pipe 82 connected to the downstream end of the trap body 81. Usually, this type of drain trap 80 is handled in a state where the trap body 81 and the instrument drain pipe 82 are integrally connected in the distribution market.
The upstream end of the trap body 81 is connected to the disposer 90. Further, the downstream end of the instrument drain pipe 82 is connected to the side branch pipe 92 via an L-shaped joint (elbow) 91. The joint 91 and the side branch pipe 92 are piped under the floor.
The instrument drain pipe 82 has an upstream end bent in an inverted U shape. For this reason, the drain trap 80 is generally called an S trap because of its outer shape including the U-shaped trap body 81 and the instrument drain pipe 82, and FIG. 8 illustrates this S trap. FIG. 9 shows a general drain trap alone. In FIG. 9, the S trap is indicated by a two-dot chain line. On the other hand, a so-called P trap in which the instrument drain pipe 83 extends in a substantially horizontal direction is indicated by a solid line in the figure. The difference between the S trap and the P trap is that the instrument drain pipe extends downward or horizontally.
In this specification, the instrument drain pipe refers to a pipe portion on the downstream side of the wear (overflow surface L) of the trap body 81.
A guide pipe 84 is provided at the downstream end of the inverted U-shaped portion 82a of the appliance drain pipe 82 and at the upstream end of the straight pipe portion 82b so as to extend upward coaxially with the straight pipe portion 82b. . An extension guide pipe 86 (which can be regarded as a part of the guide pipe 84) is connected to the guide pipe 84. Although the illustration of the extension guide pipe 86 is omitted, as described in the second embodiment, It is piped along the back of the ceiling, and its base end is fixed to, for example, a penetrating part KS (fixing means) of the vertical wall S that divides the dedicated part P in the house and the shared part C outside the house. The extension guide pipe 86 is piped with an appropriate angle gradient in a direction downward to the drainage stack side. Thereby, it is possible to prevent the reverse flow of the cleaning water (the cleaning water flows out from the cleaning port on the common part C side).

According to the cleaning facility 110 of Embodiment 3 described above, a hose with a cleaning nozzle (omitted in FIG. 8) is inserted into the base end portion of the extension guide pipe from the shared section C outside the house, and the guide pipe 84 is Then, the pipes can be made to enter the connecting pipe and the drainage horizontal branch pipe to clean the inside of these pipes. Therefore, since the drainage path can be cleaned without inserting a hose with a cleaning nozzle from the drain outlet of the kitchen sink, this type of cleaning operation can be performed without giving the residents unsanitary feeling. Moreover, since the base end portion of the extension guide pipe (guide pipe) is fixed to the common part C outside the residence, the cleaning operator can perform the cleaning work without entering the residence, and therefore the resident is not at home. Even if it is a case, the cleaning operation can be performed.
In recent years, the following problems have arisen with respect to maintenance such as cleaning inside a drain pipe or a drain pipe joint (hereinafter simply referred to as a drain pipe) in an apartment house. That is, the cleaning operation in the drain pipe is usually performed by opening the cover of the cleaning port provided in the drain pipe or drain pipe joint, inserting a hose with a cleaning nozzle, and removing the part of the drain pipe where the cleaning water should be cleaned from the cleaning nozzle. Taking this into consideration, this hose is extended while being injected obliquely forward or backward to enter the inner part of the drain pipe, and on the contrary, it is returned from the inner part to the cleaning port side. For this reason, when performing a cleaning operation, it is necessary for an operator to enter the dedicated portion P of each dwelling unit, open the lid of the cleaning port, and insert the hose into the drain pipe on the spot. As described above, since it is necessary for the worker to enter the dedicated portion P of each dwelling unit, it is usually necessary for the resident to be present from the viewpoint of unlocking the doorway, confirming the work, or preventing crime.

However, the residents on each floor may not be able to be present at the date and time designated by the cleaning contractor for their convenience, and it may be difficult for the cleaning contractor to perform the cleaning work efficiently. Conventionally, in order to solve this problem as much as possible, with regard to cleaning the drainage stack, which is a common property of residents, for example, in a high-rise apartment house, a cleaning port for cleaning work should be provided in the drainage path every four floors. Therefore, instead of performing the cleaning work for each floor, for example, the cleaning work is performed at once for the drainage paths for four floors including the three floors on the lower floor side by entering the dedicated part P of the residence every four floors. However, in this case, for example, only the residents at every four levels need to be present at the cleaning work, so there has been dissatisfaction with being unfair among the residents at other levels.
The cleaning equipment 110 according to the third embodiment exhibits a great effect on the above problems. That is, according to the cleaning facility of the third embodiment, the hose with a cleaning nozzle can be entered into the drainage path from outside the dedicated part of the residence to clean the inside of the pipe. Since there is no need to enter, and therefore no resident presence is required, any resident is freed from the inconvenience of being witnessed for cleaning, and the cleaning operator can also perform the cleaning operation efficiently.
Further, in this case, it is only necessary to arrange a cleaning port for the cleaning work in the common part C of each floor. Therefore, by performing the cleaning operation of the drainage path for each floor, the four levels through the cleaning port in one place. More advantageous cleaning can be performed as compared with the case where the drainage stack is cleaned.
Further, according to the cleaning equipment 110, the hose with the cleaning nozzle is inserted into the drainage path through the guide pipe 84 provided in the drain trap 80, so a so-called disposer (garbage grinder) is attached to the kitchen sink 20. Even in this case, the drainage passage can be efficiently cleaned. This is because a hose with a cleaning nozzle cannot be inserted from the drain of the kitchen sink 20 when the disposer is attached.

The third embodiment described above can be implemented with various modifications. For example, the guide pipe 84 extending upward in the same axis or substantially parallel to the straight pipe portion 82b is illustrated, but the guide pipe 85 is provided so as to extend obliquely upward from the upper portion of the straight pipe portion 82b as in the cleaning equipment 114 shown in FIG. In this case, the same effect as described above can be obtained. Further, when the extension guide pipe 86 is connected to the guide pipe 85, the connection method is arbitrary. For example, the extension guide pipe 86 is watertight with respect to the guide pipe 85 by tightening a cap nut 85a as shown in FIG. It is possible to adopt a so-called cap nut connection system that connects to the slab.
In the third embodiment, the extension guide pipe 86 is connected to the guide pipe 84 (or 85), and the base end portion of the extension guide pipe 86 is fixed to the vertical wall S that partitions the dedicated portion P and the common portion C of the residence. Although the configuration is exemplified, the base end portion of the guide pipe 84 (or 85) or the base end portion of the extension guide pipe 86 may be fixed to the lower side of the kitchen sink 20 and the front side where cleaning work is easy. (See FIG. 5). Further, in this case, a cleaning machine SC capable of winding and feeding a hose with a cleaning nozzle around the feeding device 60 and the drum 64 may be connected to the guide pipe 84 (or 85) or the extension guide pipe 86. (See FIG. 3). In this case, by connecting the connecting pipe 62c through the extension guide pipe 86 or directly to the guide pipe 84 (or 85), the hose 50 with the cleaning nozzle can be inserted into the drainage path without being exposed to the outside. In this respect as well, the residents do not feel unsanitary.

Further, as shown in FIGS. 11 and 12, a recess (commonly referred to as a sink pocket 93) is provided in the vicinity of the kitchen sink 20 for storing the dishwashing detergent 95 and the sponge 96 in a plastic container. In this case, a cleaning port 93b is provided at the bottom of the sink pocket 93 in addition to the drain port 93a, and the guide port 84 (or 85, FIG. 8 and FIG. 8) of the cleaning port 93b and the drain trap 80 is provided. 10), for example, may be connected by a flexible extension guide tube 94 (corresponding to the extension guide tube 86). In addition, you may carry out by providing a recessed part in a suitable place separately from a sink pocket . For this drainage 111, always not performed cleaning of the pipe cleaning port 93b is left closes the cap (not shown) so that the odor of the tube does not leak. Water or the like that has entered the sink pocket 93 is drained from the drainage port 93a and joined to the drainage path on the sink 20 side.
When cleaning the drainage pipe in the pipe, the cap of the cleaning port 93b is removed and a hose with a cleaning nozzle is inserted from the cleaning port 93b (not shown in FIGS. 11 and 12). The hose with the cleaning nozzle inserted from the cleaning port 93b is inserted into the drainage path through the flexible extension guide pipe 94 and the guide pipe 84 (or 85), and thereby the pipe can be cleaned. The same effect is obtained. Needless to say, these configurations can be similarly applied to the first and second embodiments.

Moreover, like Embodiment 1, 2, Embodiment 3 illustrated can be used especially suitably when a disposer is attached to the kitchen sink 20, However, As shown in FIG. 13, the waste_water | drain in the drainage path which does not have a disposer The same applies to the trap 112. Even in this case, a hose with a cleaning nozzle can be easily inserted into the drainage path by providing the guide pipe 113 on the downstream side (instrument drain pipe part) of the drain trap 112 that bends sharply. The cleaning operation can be performed efficiently without giving
Further, according to the third embodiment, the extension guide pipe 86 (or the guide pipe 84) whose base end is fixed to the vertical wall S of the common section C is detoured (turned around) to the ceiling, and the drain trap 80 is installed. Since the drain pipe 82 is connected to the top or side of the drain pipe 82, the drain side branch pipe under the floor of the so-called header pipe can also be washed (a large-sized cleaning pipe). In addition, if it is this structure, the same effect can be acquired also when the drainage horizontal branch pipes under a floor are made to merge.
Furthermore, the present invention can be used particularly suitably for the cleaning operation of the illustrated drainage horizontal branch pipe 30, but is also applicable to cleaning the inside of the drainage stack, the horizontal drainage main pipe, and the pipe joint that forms each junction. Even in these cases, the same effects as described above can be obtained.

Further, for example, as shown in FIG. 14, in addition to the extension guide tube 86 (72) described above, guide tubes exclusively for cleaning the standing tube (dedicated guide tubes 130 to 130) can be arranged in parallel. The dedicated guide tubes 130 to 130 are piped, for example, every four levels. In addition, it is also possible to pipe this dedicated guide pipe 130 at all levels.
One end side of each dedicated guide tube 130 is fixed to a vertical wall S that divides the dedicated portion P and the common portion C of the residence, and serves as a cleaning port through which the hose 120 with the cleaning nozzle enters. Further, the other end side of each dedicated guide pipe 130 is connected to drainage stacks 131 and 132 via a drainage stacking joint 140 to be described later in the dedicated part P of the residence.
According to this configuration, the drainage path from the kitchen drainage port to the side branch pipe 133 is cleaned by allowing the hose 50 with the cleaning nozzle to enter the drainage path in this range through the extension guide pipe 86 (72) as described above. On the other hand, the drainage paths in the drainage stacks 131 and 132 can be cleaned by allowing the hose 120 with the cleaning nozzle to enter the drainage path in this range via the dedicated guide pipe 130. In general, the cleaning nozzle of the hose 120 with a cleaning nozzle used for cleaning the drainage stacks 131 and 132 is the cleaning of the hose 50 with a cleaning nozzle for cleaning the drainage path in the range from the kitchen drainage port to the side branch pipe 133. Larger than nozzles and thicker hoses are used, so it may be difficult to smoothly enter a drainage path with relatively many bent parts from the kitchen drainage outlet to the side branch pipe. .
Furthermore, when cleaning the inside of the drainage stacks 131 and 132, it is necessary to inject a larger amount of water at a higher water supply pressure than when cleaning the inside of the horizontal branch pipe 133 and to clean it for a long time. From the above, the cleaning of the drainage stacks 131 and 132 can be performed as a separate operation from the cleaning of the drainage path in the range from the kitchen drainage port to the side branch tube 133, so that a reliable and efficient cleaning operation can be performed. Desirable from the viewpoint of doing.

From this point of view, according to the above Symbol dedicated guide tube 130, it can be cleaned Drainage 131 efficiently. That is, the hose 120 with the cleaning nozzle can be entered from the vertical wall S of the common part C, and the hose 120 with the cleaning nozzle can be directly entered into the drainage stacks 131 and 132 through the dedicated guide pipe 130. The nozzle-equipped hose 120 can smoothly enter the drainage stacks 131 and 132. If the noise on the ceiling is disliked during the cleaning operation, a dedicated guide tube 130 may be provided under the floor.
Next, a drainage pipe joint 140 suitable for the case where the dedicated guide pipe 130 is used will be described. FIG. 15 shows the drain pipe joint 140 alone. The drainage pipe joint 140 includes an upper receiving port 141 for connecting the upstream drainage stack 131, a lower connection part 142 for connecting to the downstream drainage stack 132, and mainly for kitchen drainage and disposer drainage. A horizontal branch pipe receiving port 143 for connecting the horizontal branch pipe 133 and a guide pipe connecting port 144 for connecting the dedicated guide pipe 130 are provided. The guide pipe connection port 144 is bent upward in an L shape from the side part of the body part 145 of the drain pipe joint 140 and opens upward.
The dedicated guide tube 130 connected to the guide tube receiving port 144 extends upward from the guide tube receiving port 144 to the ceiling back R, and is piped at a high position along the ceiling back R. It reaches near the upper end. The range along the back of the ceiling of the dedicated guide pipe 130 is inclined at an appropriate angle in the direction going down to the drainage stack side. An end portion of the dedicated guide tube 130 fixed to the vertical wall S of the shared portion C is opened to serve as a cleaning port. This cleaning port is normally closed by a lid H and is opened when the drainage stack is cleaned. By piping the dedicated guide pipe 130 at a relatively high position along the ceiling back R of the house as described above, the degree of freedom of piping can be increased.
Further, when the dedicated guide tube 130 can be piped in the wall, the dedicated guide tube 130 extends laterally from the guide tube receiving port 144 as shown by a two-dot chain line in the figure, and is located at a relatively low position in the wall. It is also possible to pipe up to the vertical wall S of the common part C along (waist height). The end portion of the dedicated guide tube 130 fixed to the vertical wall S is opened as a cleaning port as in the case of the ceiling back piping, and is always closed by a lid H.

As described above, since the dedicated guide pipe 130 is provided separately from the guide pipe 72 (extension guide pipe 86), the hose 50 (or 120) with the cleaning nozzle suitable for the drainage path is used in the cleaning operation. The entire drainage path can be cleaned efficiently and reliably. That is, since the guide pipe 72 or the extension guide pipe 86 is piped from the inside of the exclusive part P of the residence to the common part C through the vertical wall S, the cleaning operator passes through the guide pipe 72 or the extension guide pipe 86. The relatively small hose 50 with a cleaning nozzle can enter the drainage path from the common part C to perform the cleaning operation of the side branch pipe 133 and the like. In addition, by passing through the dedicated guide tube 130, the cleaning operator can directly drain the drainage standpipe while avoiding the drainage path that bends the relatively large hose 120 with the cleaning nozzle from the household appliance to the drainage horizontal branch tube 133 and relatively complicatedly. 131 and 132 can be made to enter, so that the drainage stacks 131 and 132 can be efficiently cleaned.
In place of the drainage pipe joint 140 described above, drainage pipe joints 160 to 170 having a form as shown in FIGS. 16 and 17 can be used, for example. Unlike the drainage pipe joint 140, the drainage pipe joint 160 shown in FIG. 16 is set on the lower surface side of the concrete slab C, unlike the drainage pipe joint 140.
The drainage pipe joint 160 connects an upper receiving port 161 to which the upstream side stand 131 is connected, a lower connection part 162 connected to the downstream side stand 132, and a lateral branch pipe (not shown). A side branch pipe receiving port 163 and a guide pipe receiving port 164 for connecting the dedicated guide pipe 130 are provided. The lower connecting portion 162 protrudes toward the lower surface side of the concrete slab C, and is connected to the downstream side vertical pipe 132 at the protruding portion.

The guide tube receiving port 164 is opened upward as described above. A dedicated guide tube 130 is connected to the guide tube receiving port 164.
A drainage pipe joint 170 shown in FIG. 17 can be suitably used for a drainage path of a super high-rise apartment or the like, and has an upper receiving port 172 for connecting a large-diameter trunk 171 and an upstream side stand 131. The lower connecting portion 173 connected to the downstream standing tube 132, the two side branch tube receiving ports 174 and 174 for connecting the side branch tube 133, and the guide tube receiving port for connecting the dedicated guide tube 130 175. The guide pipe receiving port 175 is also opened upward, and one end side of the dedicated guide pipe 130 piped up and down is connected. The other end side of the dedicated guide tube 130 is always open to the vertical wall S that divides the dedicated portion P and the shared portion C, and the hose 120 with the cleaning nozzle for cleaning the standing tube is allowed to enter from the shared portion C. Can be done.
Also with the drainage pipe joints 160 and 170 as described above, the hose 120 with the cleaning nozzle is directly entered into the drainage stacks 131 and 132 from the common part C through the dedicated guide pipe 130 connected to the guide receiving ports 164 and 175. Therefore, the inside of the drainage stacks 131 and 132 can be cleaned efficiently.
Further, as shown in FIG. 18, unlike the collecting pipe joint, it does not include a side branch pipe receiving port for connecting a side branch pipe, but includes only a guide pipe receiving port 180a extending upward in a U shape or a Y shape. A so-called upright tube 180 is inserted in the vertical tube at each level or every four levels, and the dedicated guide tube 130 is connected to each guide tube receiving port 180a, so that the residents are not bothered and unfair. The drainage stack can be efficiently cleaned without giving it .
Further, the dedicated guide pipe 130 may be piped along the bottom of the dedicated section P in addition to the configuration of piping along the ceiling back R or along the waist height in the wall of the dedicated section P. In FIG. 14, the floor F of the dedicated part P is indicated by a two-dot chain line. In any case, it is desirable from the viewpoint of preventing the backflow of the washing water that the dedicated guide tube 130 is provided with a gradient at an appropriate angle in the direction going down to the drainage stack side.

Furthermore, the cleaning facility 114 described in the third embodiment can be further modified. In the third embodiment, the configuration in which the guide pipe 84 (85) is provided in the instrument drain pipe 82 of the drain trap 80 is exemplified. For example, the cleaning facility 200 shown in FIG. 19 is used to connect the drain trap 205 to the disposer 22. The third embodiment is different from the third embodiment in that a guide pipe 202 is provided on the inflow leg 201. In this case, the extension guide pipe 203 (204, 206) is connected to the guide pipe 202, and the hose with the cleaning nozzle is passed through the extension guide pipe 203 (204, 206) and the guide pipe 202 in the drain trap 205 (trap body 205a, The cleaning is performed by entering the instrument drain pipe 205b) and further entering the downstream drainage path. According to this configuration, the drain trap 205 can be cleaned in addition to the above-described effects.
The base end 203a of the extension guide tube 203 may be fixed below the kitchen sink 20 as shown in FIG. 5, or may be connected to the cleaning port 93b of the sink pocket 93 as shown in FIG. Good. In the latter case, a flexible and relatively short extension guide tube 203 can be used (see FIG. 12). According to the cleaning facility 200, the hose with a cleaning nozzle is inserted through the extension guide tube 203 and the guide pipe 202 by removing the eye plate of the cleaning port 93b and inserting the hose with the cleaning nozzle from the cleaning port 93b. Can enter . Na us, in this case, is increased to the cleaning nozzle curvature 205R drain trap may be easily passed.
Conventionally, when the disposer and drain trap are installed under the kitchen sink, and the drain side branch pipe on the downstream side is washed through the washing nozzle and hose, the drain trap can be removed. There was a tendency for the work to be troublesome and the surroundings to become dirty.

Further, by using a longer extension guide tube 204 instead of the extension guide tube 203, the base end portion 204a is not connected to the sink pocket 93 but to the dedicated portion P of the building as shown by a two-dot chain line in FIG. it can be fixed to the through portion KS of the vertical wall S partitioning the shared portion C. If this is the extension guide tube 204 after laying laterally along the ceiling above the sink 20, it is possible to adopt a path that fall along the counter portion F mounted faucet J tap. In the range along the back of the ceiling of the extension guide tube 204, the backflow of the cleaning water to the cleaning port side can be prevented by providing a gradient at an appropriate angle in the direction going down to the guide pipe 202 side. Further, by setting the base end portion 204a as the cleaning port at a high position near the upper end portion of the vertical wall S, it is possible to prevent mischief such as throwing of foreign matter into the cleaning port. These points are the same as those of the embodiment exemplified above.
Further, similarly as shown by a two-dot chain line in FIG. It is good also as a structure fixed to the vertical wall W which divides S, or the structure which fixes the base end part 207a of the extension guide pipe | tube 207 to the upper surface of the counter part F to which the tap J of the water supply was attached. Also with these configurations, the hose with a cleaning nozzle is inserted into the drainage path from the guide pipe 202 provided on the inflow leg 201, so that not only the connection pipe 208 and the side branch pipe 209 but also the drainage trap 205 is cleaned. Can be done.
As shown in FIG. 20, a side branch pipe 209 is connected to the downstream side of the instrument drain pipe 205 b of the drain trap 205 through a connecting pipe 208. The horizontal branch pipe 209 is connected to the drainage stack 211 via a pipe joint 210. Here, when the drain trap is not an P trap (U trap) but an S trap as shown in FIG. 20 (see FIG. 8 and FIG. 10), a similar structure can be obtained by providing a guide pipe on the inflow leg. Needless to say, the effect is obtained. Further, since the cleaning port 93b is located upstream of the drain trap, a deodorizing cap (rubber plug) is not required, and it is sufficient to simply place a eye plate. Further, the drain trap may be made of resin, made of brass or cast iron.

The embodiment exemplified above has the following unique advantages. The advantage is that the resident himself temporarily connects a short bellows tube or hose to the spout JK of the tap J and discharges the tip of the tap toward the cleaning port 93b. It can be washed to some extent for convenience.
Although not shown, the extension guide pipe 203 is not directly connected to the guide pipe 202 shown in FIG. 20, but a branch pipe 220 is connected as shown in FIG. Will be able to do. A guide pipe 72 is connected to the first horizontal receiving port 220 b of the branch pipe 220, and a base end portion 72 m is fixed to the lower side of the sink 20 via a bracket 221. An extension guide tube 204 (206, 207) is connected to the second lateral receiving port 220c of the branch tube 220. The base end portion of the extension guide tube 204 is fixed to the upper portion of the vertical wall S as illustrated above, and the base end portion of the extension guide tube 206 is connected to the pipe shaft P.P. The base end of the extension guide tube 207 is fixed to the upper surface of the counter portion F. The extension guide tube 203 is connected to the upper receiving port 220 a of the branch tube 220, and the base end portion 203 a is connected to the cleaning port 93 b of the sink pocket 93. By using such a configuration, it is possible to provide a cleaning facility that has all the conveniences obtained by the embodiment described above. The branch pipe does not have the three receiving ports 220a, 220b, and 220c shown for convenience, but an ordinary T-shaped branch pipe or Y-shaped branch pipe is used to pass the cleaning nozzle through a predetermined path.
Further, for example, as shown in FIG. 24, the connecting pipe part is provided at the cleaning port 271 provided on the upper surface of the counter part F and is connected to the connecting pipe part 270 and the downstream end thereof is provided on the downstream side of the drain trap 205. The cleaning port 271 may be provided as a dedicated cleaning port for the drainage stack. As a result, the number and distance of bends in the drainage path are reduced, and a thick nozzle and hose for cleaning the standpipe 211 alone can be passed.

Next, a case where the disposer is not installed in the kitchen sink and the drain pipe (drainage path) is washed by so-called washing will be described. In this case, as shown in FIG. 22, the drain outlet at the bottom of the kitchen sink 20 is provided with a recess 250 instead of the one-trap drain trap 27 shown in FIGS. 6 and 7, and garbage is stored in the recess 250. 1 is connected to one end side (upstream side) of a flexible extension guide tube 252 and the other end side (downstream side) of the extension guide tube 252 is connected to a connection port 250a provided at the bottom of the recess 250. A rubber plug (not shown) that is connected to the inflow leg of the P trap (or S trap or U trap) 253 and that blocks the flow of drainage can be attached to the connection port 250a of the recess 250.
According to this configuration, the basket 251 is removed from the recess 250 and a rubber plug is attached to the connection port 250a of the recess 250, so that an appropriate amount of water is stored in the sink 20, and then the water stored by pulling out the rubber stopper is collected at once. The drainage path below the extension guide pipe 252 can be washed by flowing. In this case, since the above-described hose with a cleaning nozzle is not required, the resident himself can easily clean the drainage path in daily life. This cleaning method corresponds to one embodiment of the invention described in claim 1 .
FIG. 23 shows a case where washing is performed for the above reasons when a disposer is installed in the kitchen sink. In this case, at the bottom of the kitchen sink 20, a drain port 261 to which a disposer 260 is attached and a cleaning port 263 to which a flexible extension guide tube 262 is connected are provided. The extension guide pipe 262 is connected to the inflow leg 266 a side of the drain trap 266. In addition, rubber plugs 264 and 265 for blocking the flow of drainage can be attached to the drainage port 261 and the cleaning port 263, respectively. An inflow leg 266 a of a drain trap 266 is connected to the downstream connection port 260 a of the disposer 260.

According to this configuration, the drain port 261 is closed with the rubber plug 264, the cleaning port 263 is closed with the rubber plug 265, and in this state, water is allowed to flow from a tap (not shown), and an appropriate amount of water is poured into the sink 20. Save up. After that, by removing only the rubber stopper 265 on the cleaning port 263 side and allowing the stored water to flow through the extension guide pipe 262 to the drainage path at once, the sink 20 with a disposer can also be washed for the drainage path. it can. You may collect water in the washing bowl and let it flow. If the amount of water used for transporting garbage that has been crushed by the disposer tends to be insufficient every day, an effect for drainage pipe maintenance can be expected. This cleaning method corresponds to one embodiment of the invention described in claim 2 .
Therefore, a so-called eye plate is always attached to the washing port 263 for washing and is used as a drain port. Needless to say, the rubber plug 264 is attached to the drain outlet 261 only during washing. The rubber stopper may be always attached.
Further, in FIG. 22, the basket 251 is removed from the concave portion 250, and the outlet JK of the faucet J (a bellows tube or the like may be temporarily attached) is jetted toward the connecting port 250a without covering the connecting port 250a. In this case, or by spraying water toward the cleaning port 263 with the rubber plug 265 removed in FIG. 23, the drainage path can be easily cleaned. In addition, the drainage path can be cleaned without giving a sense of unsanitary to the residents by these cleaning methods (washing).
Furthermore, according to the washing method by washing or sinking for the above reasons, there is a problem that the oil and fat etc. adhere to the inner surface of the drain pipe of the kitchen sink of the apartment, and the horny and slime with the passage of time and the pipe diameter is reduced. You will be able to handle proactively in your daily life.
In addition, the drainage pipe on the downstream side of the conventional disposer has a tendency to greatly reduce the cleaning effect on the inner surface of the drainage pipe due to the resistance when passing through the inside of the disposer even if the washing water flows. By adopting the drain pipe cleaning method exemplified above, the drain pipe can be cleaned efficiently. However, in the case where the above-exemplified drain pipe cleaning method (irrigation, flushing) is performed simultaneously in a plurality of dwelling units, the cleaning port 93b (connection port 250a, cleaning port 263) for irrigation or flushing is used. Since the drainage flows through the above-described path without passing through the disposer, the flow rate in the drainage stack is overloaded and an excessive negative pressure is generated. As a result, the drain trap may be shut off. Therefore, the pipe diameter (eg, 100A) based on the standard design method for the drainage stack pipe is made to be one size up (eg, 125A) to prevent the above-mentioned seal water breakage, and slime over time. The possibility of extending the life of the drainage standpipe can be expected even if the diameter of the pipe becomes narrow due to adhesion.

FIG. 25 shows a cleaning facility 300 that uses a combination of a washing method or a flushing method and a high-pressure cleaning method using a hose 50 with a cleaning nozzle. This cleaning equipment 300 can be suitably used for the kitchen sink 20 in which the disposer 260 is attached to the drain outlet 261. The kitchen sink 20 is provided with a cleaning port 263 in addition to the drain port 261 and can be sealed watertight by lids 264 and 265, respectively. The cleaning port 263 is connected to the inflow leg 266 a of the running trap 266 through the extension guide tube 262. With this configuration, since the above-described example is given, washing or flushing can be performed. Therefore, according to washing or flushing, the drainage path from the running trap 266 to the drainage lateral branch pipe 30 can be washed.
The cleaning equipment 300 includes a feeding device 60 that can wind up and feed the hose 50 having the cleaning nozzle 54. The feeding device 60 is connected to the upstream side of the drainage horizontal branch pipe 30 via the guide pipe 40 and the T-shaped joint 44. The hose 50 fed out from the feeding device 60 enters the drainage horizontal branch pipe 30 and the drainage stack 34 through the guide pipe 40 and the T-shaped joint 44, and thereby the drainage horizontal branch pipe 30 and the drainage stack 34. The inside can be washed at high pressure. The feeder 60 includes an electric drum that rotates using an electric motor as a drive source. The hose 50 can be wound and fed out by a switch operation, and the washing water can be automatically injected and stopped from the washing nozzle 54. It is a formula. For this reason, by using this cleaning equipment 300, even an elderly person or the like can easily perform the cleaning operation of the drainage channel, thereby allowing residents to live in daily life without entrusting the cleaning of the drainage channel to a specialist. Can be performed frequently, so that a smooth flow of drainage can be maintained at all times.

The feed device 60 has been illustrated as a fixed type that is fixed to the lower side of the kitchen sink 20 (FIGS. 1 to 4). Instead, for example, a mobile feed device (portable type) as shown in FIG. High pressure washer 400) can also be used. The portable high pressure washer 400 includes a flexible guide tube 404 for guiding the hose 50 with a cleaning nozzle, a take-up drum 401 for winding and feeding the hose 50 with a cleaning nozzle, and a rotatable drum 401. A frame 402 to be supported, one front wheel 403 rotatably attached to the front portion of the frame 402, two rear wheels 405 and 405 rotatably attached to the rear portion, and provided to extend upward from the rear portion of the frame 402 A hand push handle 406 is provided. The take-up drum 401 may be an electric type as illustrated above, or may be a manual type take-up drum. The take-up drum 401 is housed in a case 407 and a frame 402. A water supply port 408 for supplying cleaning water to the nozzle-equipped hose 50 is provided on the front surface of the frame.
One end side 404 a of the guide tube 404 is fixed by being tied to the upper portion of the hand handle 406 with a string. The hose 50 with a cleaning nozzle is entered from one end side 404 a of the guide tube 404. On the other hand, the other end side 404b of the guide pipe 404 is connected to a cleaning port 35a of a joint 35 with a cleaning port of a kitchen sink drainage system connected to, for example, the drainage stack 34 of the common section C shown in FIG. The washing machine 400 having this configuration corresponds to an embodiment of the invention described in claim 7 .
Through this guide tube 404, the hose 50 with a cleaning nozzle is caused to enter the drainage path from the shared section C side. As will be described later, it is desirable that the entry range of the hose 50 with the washing nozzle is a range (high pressure washing region) downstream from the drain trap by an appropriate distance.
According to such a portable high-pressure washing machine 400, the drainage path can be efficiently washed even on a high-rise floor such as a super high-rise building or a condominium.

Next, as a drain pipe cleaning method, a so-called station system can be adopted. In this station system, a 200V power outlet, a faucet, and a drain outlet are provided in the vicinity of the elevator at every four-layer pitch from the lowest floor of the apartment house, and a common-part drainage standpipe and a common-use drainage pipe using an electric power driven mini-jet washing machine. The drainage horizontal branch pipe in the dwelling unit is cleaned.
By setting the above-mentioned station system to the pitch of each layer, if the drainage horizontal branch pipe in each dwelling unit is washed from the joint provided in the drainage standpipe of the common part, the residents can wash or If washing is performed, there is no need to bring the washing nozzle close enough that the sealing water of the drain trap is sucked off during high-pressure washing. Separate sealing water supply facilities can be omitted.
That is, the sealing depth of the drain trap is 50 mm if it is generally commercially available in accordance with the Air Conditioning and Sanitation Engineering Society Standard (HASS206-2000). In this case, the sealing water loss should be 25 mm or less. Although it is installed, a hose with a cleaning nozzle enters the drainage path of the drainage branch pipe from the cleaning port of the drainage standpipe piped in the common part of the building, and enters the drainage trap near the drainage trap to increase the pressure. When cleaning is performed, the sealing water is sucked off, and as a result, the odor in the drain pipe may leak into the room. For this reason, the entry range (maximum entry distance) of the hose with a cleaning nozzle is limited to a range in which the sealing water loss is maintained at 25 mm or less (a range in which the sealing water is not absorbed, hereinafter referred to as a “high pressure cleaning region”). Therefore, it is necessary not to enter the vicinity of the drain trap more than necessary. This cleaning method is shown in FIG.
In the case of this cleaning method, the upstream side of the high-pressure cleaning region (hereinafter referred to as “reservoir region”) can be performed by washing or sinking as described above. In FIG. 26, the symbol X indicates the boundary between the high pressure cleaning region and the cleaning region. The boundary X is desirably as downstream as possible from the drain trap. However, it is desirable to set the region where the cleaning effect in the pipe is remarkable by washing or the like as the washing region. This cleaning method corresponds to an embodiment of the invention described in claim 6 .

  In addition, the wastewater from the disposer falls in the drainage standpipe before the water, and accumulates in the shape of a weir near the end of the bent joint of the leg joint. It will be transported to. However, as a result of experiments, it has been found that there is a problem that some egg shells remain. At present, the disposer wastewater is introduced into the wastewater treatment tank alone. However, in view of the above problems, if wastewater other than sewage, especially the wastewater from the bathtub is joined to the collective joint of the drainage standpipe of the disposer system, It is considered that there is a merit that not only the improvement of the transportability but also the adhesion of oil and fat is reduced.

Next, a drainage facility 500 obtained by further modifying the above-described third embodiment will be described. The drainage facility 500 corresponds to an embodiment of the invention described in claim 8. The drainage facility 110 according to the third embodiment shown in FIGS. 11 and 12 is provided with a cleaning port 93b in addition to the drainage port 93a at the bottom of the sink pocket 93 provided in the kitchen sink 20, while the drainage of the drain trap 80 is performed. The pipe 82 is provided with a guide pipe 84 (85), and the guide pipe 84 (85) and the cleaning port 93 b of the sink pocket 93 are connected via a flexible extension guide pipe 94. According to the above, by allowing the hose with the cleaning nozzle to enter from the cleaning port 93b of the sink pocket 93, the drainage path can be efficiently cleaned without giving a sense of unsanitary to the resident.
As shown in FIG. 28, the drainage facility 500 described below has a Y-type joint 503 connected to an instrument drain pipe 502 of a drain trap 501, a branch pipe 503 a of the Y-type joint 503, and a cleaning port for the sink pocket 505. Are connected by an extension guide tube 506.
The drain trap 501 is watertightly connected to a drain outlet 511 a of a disposer 511 equipped on the kitchen sink 510 via a cap nut 521. An instrument drain pipe 502 is connected to the downstream side of the drain trap 501 through a cap nut 522 in a watertight manner. Further, a Y-shaped joint 503 is connected to the downstream side of the appliance drain pipe portion 502 through a cap nut 523 in a watertight manner. One end of the extension guide pipe 506 is connected to the branch pipe portion 503 a of the Y-shaped joint 503. The other end of the extension guide tube 506 is connected to the cleaning port of the sink pocket 505. A flexible hose is used for the extension guide tube 506.
On the other hand, the cleaning port of the sink pocket 505 is airtightly closed by a lid (not shown) at normal times when cleaning is not performed.
According to the sink pocket type cleaning equipment 500 configured as described above, the sink pocket 505 can be washed off by removing the lid of the cleaning port and allowing water to flow from the tap J of the water supply. In addition, a certain amount of water is applied to the sink pocket 505 with the lid of the cleaning port closed, and thus the rear lid is removed to perform washing. For this reason, the resident or the like can easily clean the drainage path downstream of the Y-shaped joint 503 by washing or the above-described washing.
Moreover, if the cap nuts 521 and 522 are loosened, the drain trap 501 can be easily removed, and the drain trap 501 can be carefully cleaned alone. Since the drain trap 501 can be easily removed, it is possible to frequently check the degree of contamination. For this reason, it is not necessary to use a transparent tube for the drain trap 501. The sink pocket type cleaning facility 500 described above corresponds to an embodiment of the invention described in claim 8 . For the Y-type joint 503, in addition to the branch pipe portion 503a extending 45 ° upward, a 90 ° T-type joint extending in the orthogonal direction, or a branch pipe portion having a U shape and extending upward is used. Can do.

Next, FIG. 29 shows a cleaning equipment 550 in which the washing equipment 500 of the above-described flushing system and the scrubbing system are modified. The cleaning equipment 550 is different in that the other end side of the extension guide tube 506 is connected to the water supply rather than the cleaning port of the sink pocket 505. The same members and configurations as those of the cleaning equipment 500 are denoted by the same reference numerals, and the description thereof is omitted.
The extension guide pipe 506 is connected to a water supply pipe 551 that constitutes a water supply path of the middle water supply via an open / close valve 552.
The opening / closing valve 552 includes a rotary knob 552a for opening / closing operation, and is installed around the kitchen sink 510 as shown in the figure and can be easily opened / closed by a resident.
In general, “chusui” is a collection of used water, such as rainwater or remaining hot water from a bath. For example, toilets and fountains can be reused as needed to make effective use of water resources. It is intended and is supplied by piping on a completely different route from the water supply used for drinking water or the like. In this specification, “middle water” includes, in addition to the above-mentioned used water, water that has been once drained from a tap of a water supply (so-called non-directly connected water).

According to the middle water type cleaning facility 550 described above, when a resident opens the knob 552a of the opening / closing valve 552 when cleaning the drainage path, the middle water is supplied to the drainage path via the extension guide pipe 506. Since it is washed, even a resident or the like can easily wash the drainage channel without giving off a strange odor to the room. This middle-water cleaning facility 550 corresponds to an embodiment of the invention described in claim 9 .
In addition, since the cleaning water is not supplied through a piping route directly connected to the water supply, but is washed using non-directly connected water (medium water), it does not hit a so-called cross connection.
The cleaning facility 550 can be further modified. For example, as shown by a two-dot chain line in FIG. 29, a guide pipe 511b is branched from the drain outlet 511a of the disposer 511, and one end of the extension guide pipe 506 is connected to the guide pipe 511b in a watertight manner. The cleaning may be performed by supplying from the upstream side of the drain trap 501.

Next, a description will be given of another type of cleaning facility 600 that is a sink-type cleaning facility that uses intermediate water and is different from the above-described cleaning facility 550. Although the cleaning facility 550 is a permanent facility that is always installed with respect to the drainage path, the cleaning facility 600 described below is an emergency cleaning facility that is connected to the drainage path only during a cleaning operation. FIG. 30 shows an outline of the cleaning facility 600. This cleaning facility 600 is configured to use the remaining hot water of the bath as the intermediate water.
As shown in FIG. 30, the water supply pipe 551 constituting the middle water supply is connected to a water supply hose 565 connected to the discharge port 561 of the water absorption pump 560. The water absorption pump 560 is a portable inverter pump and includes a pump body P that is operated by an inverter motor M. This inverter motor M operates with a normal household power supply (100 V). The other end of a water absorption hose 563 whose one end is immersed in the remaining hot water of the bathtub 564 is connected to the water supply port 562 of the water absorption pump 560 in a watertight manner.

According to the cleaning equipment 600 configured as described above, when the water absorption pump 560 is operated with the opening / closing valve 552 opened, the remaining hot water (middle water) in the bathtub 564 becomes the water absorption hose 563, the water supply hose 565, the opening / closing valve 552, and It is supplied to the downstream side of the drainage trap 501 through the extension guide pipe 506, whereby the drainage path can be easily cleaned by a resident or the like. Moreover, since it is the structure which connects the water supply hose 565 of the water absorption pump 560 to the opening-and-closing valve 552, the odor etc. in a drain pipe can be prevented.
By using a hose coupling (one-touch close-open female / male joint) to connect the water supply hose 565 to the open / close valve 552, the water supply hose 565 can be easily connected to and disconnected from the open / close valve 552. Thus, the cleaning facility 600 can be made portable and convenient to carry. In the present embodiment, the hose coupling has a male-side connector and a female-side connector that are connected to each other, and when connected to each other, each drainage pipe (in this example, the extension guide pipe 551 and the water supply hose 565). Are connected in a watertight manner and have a function of hermetically closing the end of each drain pipe when disconnected, and can be connected and disconnected with a single touch.

By using the hose coupling described above, the cleaning facility 600 can be used in the following form. For example, one or more portable water absorption pumps 560 are installed on each floor of an apartment house, and each resident is installed downstream of a drain trap 501 in a kitchen sink as needed. It is good also as a structure to connect. This configuration is shown in FIG.
As shown in the drawing, a Y-type joint 503 is interposed on the downstream side of the drain trap 501, and a female side connector 570a of a hose coupling 570 is attached to a branch pipe portion 503a of the Y-type joint 503. On the other hand, the male connector 570b of the hose coupling 570 is attached to the tip of the water supply hose 565 of the water absorption pump 560. By connecting the female side connector 570a of the hose coupling 570 to the male side connector 570b, the water supply hose 565 can be connected in a watertight manner to the branch pipe portion 503a. The remaining hot water (medium water) is supplied to clean the inside of the drain pipe. This configuration corresponds to an embodiment of the invention described in claim 10 .
As described above, the male-side connector 570b is disconnected by attaching the female-side connector 570a of the hose coupling 570 to the branch pipe portion 503a of the Y-shaped joint 503 that is interposed in the falling portion on the downstream side of the drain trap 501. Even in this state, the female connector 570a is hermetically closed, so that the odor in the drain pipe can be prevented from leaking outside.

Next, in FIG. 32, the female side connector 570a of the hose coupling 570 is attached to the tip of the extension guide pipe 506 connected to the branch pipe portion 503a of the Y-shaped joint 503, and this female side connector 570a is attached to the kitchen sink. A water supply hose for the extension guide pipe 506 is provided on the front wall 512 by attaching a male connector 570b (not shown in FIG. 32) to the tip of the water supply hose 565 connected to the water absorption pump 560. The connection and disconnection of 565 can be easily performed, so that the drainage pipe can be easily cleaned by a resident.
FIG. 33 also shows a cleaning in which a female-side connector 570a of a hose coupling 570 is arranged on the front wall 512 of the kitchen sink, and the female-side connector 570a and the open / close valve 552 are connected via an extension guide tube 551. Equipment 600 is described. Also in this case, the male connector 570b (not shown in FIG. 33) of the hose coupling 570 is attached to the tip of the water supply hose 565 connected to the discharge port of the water absorption pump 560. By connecting the male-side connector 570b and the female-side connector 570a of the hose coupling 570, the water supply hose 565 can be easily connected to the downstream side of the drain trap 501 through the open / close valve 552. On the contrary, when the cleaning operation is not performed, by disconnecting the connection of the hose coupling 570, the water absorption pump 560 can be stored in another place, so that the use of the cleaning facility is improved. Even when the hose coupling 570 is disconnected as described above, since the female side connector 570a is attached to the branch pipe portion 503a, the odor in the drain pipe does not leak to the outside.
The above-described hose coupling connection type cleaning equipment (the cleaning equipment 600 shown in FIGS. 32 and 33) corresponds to an embodiment of the invention described in claim 11 . According to these two embodiments, the hose coupling 570 can be connected and disconnected in the same manner as an electrical outlet, so that the drainage pipe can be easily and reliably cleaned by a resident or the like.

Next, in the cleaning facility shown in FIG. 31, the female side connector 570a (or male side connector 570b) of the hose coupling 570 is detachably attached to the branch pipe portion 503a of the Y-shaped joint 503. Various forms of cleaning can be performed. By connecting the female connector 570a (or male connector 570b) of the hose coupling 570 to the branch pipe portion 503a of the Y-shaped joint 503, the water absorption pump 560 can be easily connected via the water supply hose 565. This makes it possible to easily wash the drainage pipe using middle water.
Moreover, as shown in FIG. 34, the branch pipe part 503a is opened by removing the female side connection tool 570a (or the male side connection tool 570b) of the hose coupling 570 attached to the branch pipe part 503a of the Y-shaped joint 503. The inside of the drain pipe can be washed at a high pressure by allowing the hose 50 with the front injection nozzle to enter from the opening. In this case, the portable washing machine 400 described above can be used. By using this portable washing machine 400, the inside of the drain pipe can be reliably washed not by so-called pool washing or sink washing but by high pressure washing. The hose end on the water absorption side of the high-pressure washer 400 is inserted into, for example, the remaining hot water in the bathtub, so that the high-pressure washer 400 supplies middle water into the drain pipe.
In addition, although the structure which makes the hose 50 with a front injection nozzle approach directly into the branch pipe part 503a was illustrated, a washing | cleaning operation | work can be performed by using the guide pipe | tube 404 as mentioned above, without polluting the circumference | surroundings. In this case, another auxiliary guide pipe is connected in advance to the branch pipe section 503a, and this is pulled out from below the kitchen sink 510 and connected to the guide pipe 404 of the portable washer 400 in a wide workability area. The hose 50 with the front injection nozzle can be made to enter the drain pipe through the guide pipe 404 and the auxiliary guide pipe. According to this configuration, the cleaning operation can be performed without contaminating the surroundings, and the cleaning operation can be performed more easily because the connection operation of the guide tube 404 does not have to be performed in a narrow space below the kitchen sink. Can do.

Further, the hose coupling 570 can obtain the same effect by using the guide pipe 85 of the extension guide pipe 82 described above, for example, instead of using the joint 503 (see FIG. 10). That is, the water supply hose connected to the discharge port of the water suction pump 560 while attaching one of the female side connector 570a and the male side connector 570b of the hose coupling 570 to the guide pipe 85 of the appliance drain pipe portion 82 of the drain trap 80. By attaching the other of the female side connector 570a or the male side connector 570b of the hose coupling 570 to the tip of the 565, the water supply hose 565 can be easily connected to the guide pipe 85, thereby allowing the middle water to flow. The drainage pipe can be easily cleaned by using it.
Moreover, by removing one of the female-side connector 570a or the male-side connector 570b from the guide pipe 85 and opening the guide pipe 85, the hose 50 with the front injection nozzle can be entered from this opening. Thus, the inside of the drain pipe can be washed at high pressure. This configuration corresponds to an embodiment of the invention described in claim 14 .

Each embodiment described above can be further modified. For example, the water absorption hose 563 may be soaked in the remaining hot water of the bathtub 564 as described above, or may be soaked in, for example, water stored in a kitchen sink and used as medium water or stored in a bucket. It may be soaked in tap water and used as middle water.
Thus, it is not a piping path directly connected to the water supply, but is a configuration in which water that has once flowed out from the tap of the water supply is collected and used as middle water (non-directly connected water), and thus does not correspond to so-called cross connection. The purpose is to discharge the middle water having a desired pressure directly into the drainage pipe by using the middle water, and to wash it efficiently.
Moreover, it can be set as the built-in type which installs the water absorption pump 560 in the downward direction of a kitchen sink. Moreover, it can be set as the structure which pipes the water supply hose 565 which supplies middle water in the wall part of a building.
Further, by connecting a hose with a cleaning nozzle to the discharge port 561 of the water absorption pump 560 instead of the water supply hose 565, the cleaning equipment can be diverted to a middle-water type high pressure washer.

Moreover, the convenience of carrying can be aimed at by attaching the caster to the water absorption pump 560. Further, by providing a hose drum for winding up one or both of the water absorption hose 563 and the water supply hose 565, the handling facility of the cleaning equipment can be improved and stored in a small space in a compact manner. be able to.
Although it is possible to remove the running trap attached to the downstream side of the disposer and clean the drainage pipe on the downstream side, doing this work in a confined area under the sink is cumbersome, Not hygienic. Disposer traps are preferably designed to be renewed over time, for example every 10 years.
