Description

  Aspects of the invention generally relate to a drain trap cleaning system.

  Drain traps are installed on sinks, wash bowls, washroom floors in bathrooms and shower rooms, etc., to prevent backflow of odors from drain pipes. In order to discharge dirt in the drain trap, it is effective to replace the sealing water of the drain trap with new water. Conventionally, when discharging dirt in the drain trap, a large flow of water has been allowed to flow through the drain trap for the purpose of increasing the replacement rate of the sealed water (for example, see Patent Document 1).

JP 2009-213875 A

The inventor has found that when a large amount of water is passed through the drain trap, sediment dirt settled in the drain trap is discharged, but floating dirt floating in the water is difficult to be discharged. For this reason, in particular, in drainage traps such as shampoos and soaps where foam contamination is likely to occur, the substitution rate in the traps cannot be sufficiently increased, and it has been found that there is still room for improvement.
Furthermore, the inventor has found that when the large amount of water flows through the drain trap, the floating dirt enters and remains in the gap at the top of the drain trap, and is thus difficult to be discharged out of the drain trap.

In FIG. 4, the hair catcher 130 is omitted.

  As shown in FIGS. 2 to 4, the drain trap 100 includes a trap body 110, a water seal 120, a hair catcher 130, a drain pit 140, a flange 150, and a connection member 160.

  The trap body 110 is a cylindrical member extending in the left-right direction. The trap body 110 may be configured integrally by connecting a plurality of cylindrical members. The right side of the trap body 110 is bent upward, and a water outlet 181 is formed at the right end. A connecting member 160 is connected to the left end of the trap body 110. The connection member 160 is connected to the drain outlet of the bathtub 510, and the water in the bathtub 510 flows into the trap body 110 through the connection member 160.

  An opening 111 is provided in the upper part of the trap body 110, and a water inlet 180 (see FIG. 4) is formed. In the portion where the opening 111 is formed, the wall surface of the trap body 110 is bent upward, whereby a bent portion 112 (see FIG. 4) is formed. The water that has flowed into the trap body 110 from the water inlet 180 and the connection member 160 is temporarily stored inside the trap body 110 and is discharged to a pipe (not shown) through the water outlet 181.

  The trap body 110 is provided with a protrusion 113 between the water inlet 180 and the water outlet 181. By providing the protrusion 113, the depth of water (sealed water) stored in the trap body 110 can be increased. Thereby, possibility that a sealing function will be impaired by evaporation, reverse pressure, etc. of sealing water can be reduced.

  The drain pit 140 has an inner surface that inclines downward toward the center and has a width that decreases toward the bottom. The drainage pit 140 is fixed to the washing floor 520, for example.

  A lower end of the drain pit 140 is provided on the opening 111 of the trap body 110, and a flange 150 is provided on the lower end of the drain pit 140. A screw groove is formed inside the opening 111 and outside the flange 150, and the opening 111 and the flange 150 are fastened. The lower end of the drain pit 140 is sandwiched and fixed between the opening 111 and the flange 150 via the packing 151.

  The sealing cylinder 120 is detachably attached to the water inlet 180 of the trap body 110. The sealing cylinder 120 has a cylindrical part 121 and an annular part 122. The cylindrical part 121 penetrates up and down, and is configured such that drainage flows through the inside from the top to the bottom.

  A packing 123 is provided between the annular portion 122 and the drain pit 140. A gap G (see FIG. 4) is formed between the sealing cylinder 120 and the opening 111, but the gap between the annular portion 122 and the drain pit 140 is sealed by the packing 123, so that the gap The inflow of waste water to G can be prevented.

  The hair catcher 130 is detachably provided at the water inlet 180 (inside the annular portion 122). A part of the hair catcher 130 is formed in a mesh shape, and foreign substances such as hair are prevented from entering the trap body 110.

Next, the drain trap cleaning system according to the embodiment will be described with reference to FIGS.
5 and 6 are process cross-sectional views illustrating a cleaning process of the drain trap 100 by the drain trap cleaning system according to the embodiment.
FIG. 7 is a timing chart showing a cleaning process of the drain trap 100 by the drain trap cleaning system according to the embodiment.

5 and 6, the hair catcher 130 is omitted.
In FIG. 7, the horizontal axis represents time, and the vertical axis represents the presence or absence of water discharged from the water discharge unit 610 and the water level of the water W in the drain trap 100 at each timing.

  Timings t0 to t1 in FIG. 5A and FIG. 7 represent a state immediately after bathing. At this time, water does not come out from the shower, water faucet, water discharger 610, etc. of the bathroom 500, and the water level of the water W in the drain trap 100 is equal to the upper end of the protrusion 113, for example.

  As shown in FIG. 5A, various stains exist in the drain trap 100 after bathing. These stains can be mainly divided into sediment stain A and floating stain B. The sediment dirt A has a density higher than that of the water W, and is deposited on the bottom of the trap body 110. The floating dirt B is smaller in density than the water W and floats in the water W. Precipitated dirt A is, for example, a solid of human body sebum or keratin, mud or the like. The floating dirt B is, for example, shampoo or soap bubbles, sebum or keratin wrapped in bubbles.

  In the state shown in FIG. 5A, the sediment dirt A is deposited on the bottom of the trap body 110. For example, a part of the floating dirt B is floating inside the sealing tube 120 and the other part is floating outside the sealing tube 120.

  Next, as shown in the timings t1 to t2 in FIG. 5B and FIG. 7, a sediment dirt discharging process is performed in which a large amount of washing water is supplied from the water discharger 610 to the drain trap 100. When a large amount of cleaning water is supplied to the drain trap 100, the water level of the water W exceeds the upper end of the protruding portion 113, and the water W is discharged from the water outlet 181.

  At this time, the floating dirt B floating inside the sealed water cylinder 120 is washed away to the outside of the sealed water cylinder 120, and a part of the floating dirt B is discharged from the water outlet 181 along the flow of water. In addition, due to a large flow of water from the water inlet 180 toward the water outlet 181, the sediment dirt A temporarily rises and is discharged from the water outlet 181.

  On the other hand, when a large amount of cleaning water is supplied to the drain trap 100, the water level of the water W temporarily becomes higher than the lower end (the bent portion 112) of the opening 111. At this time, since the portion where the gap G between the trap body 110 and the sealing cylinder 120 is formed opens downward and has a concave shape, the water W enters the concave portion, and the water level is located in the concave portion. . Then, the floating dirt B that has entered the recess cannot flow toward the water outlet 181 by the bent portion 112, and as a result, as shown in FIG. 5B, the floating dirt B remains at the position of the gap G. A stagnation part is formed.

  Next, as shown in timings t2 to t3 in FIG. 5C and FIG. 7, a water reduction process is performed in which the amount of cleaning water supplied to the drain trap 100 is reduced. The amount of cleaning water supplied to the drainage trap 100 in this water reduction step is set to be smaller than the amount of cleaning water supplied to the drainage trap 100 in the settled soil discharging step and the floating soil discharging step described later.

By reducing the supply amount of the washing water to the drain trap 100, the water level of the water W becomes lower than that of the stagnation part and falls to the same position as the upper end of the protruding part 113, for example. At this time, as the water level of the water W decreases, the position of the floating dirt B remaining in the stagnation part also decreases.
In this water reduction step, the supply of cleaning water to the drain trap 100 may be stopped and the supply amount of cleaning water may be zero.

  Next, as shown at timings t3 to t4 in FIG. 6A and FIG. When a small amount of washing water is supplied to the drain trap 100, the water level of the water W becomes higher than the upper end of the protrusion 113, and the water W gently flows toward the outlet 181. At this time, since the water level of the water W is lower than the stagnation part, the floating dirt B is discharged from the water outlet 181 along the flow of water.

  In addition, when the water level of the water W is lowered in the water reduction process, a part of the floating dirt B adheres to a position higher than the water level of the water W, such as the outer wall of the sealing tube 120 or the inner wall of the opening 111. There is a case. Such floating dirt B is difficult to be discharged by supplying a small amount of washing water.

  For floating dirt B adhering to the wall surface, an adhering dirt removing step of supplying a large flow of washing water to the drain trap 100 is performed as shown in timings t5 to t6 in FIG. 6C and FIG. Is effective. By supplying a large amount of washing water to the drain trap 100, the water level of the water W reaches the position of the stagnation part, and the floating dirt B adhering to the outer wall of the sealing tube 120, the inner wall of the opening 111, etc. It can float and be removed from the wall. At this time, a part of the floating dirt B may remain in the stagnation part again, but at least a part of the floating dirt B can be discharged from the drain trap 100 by removing the floating dirt B from the wall surface and floating on the water W.

  Note that, as shown in timings t4 to t5 in FIG. 6B and FIG. 7, the amount of cleaning water supplied to the drain trap 100 may be reduced between the floating dirt discharging process and the attached dirt removing process. .

The control unit 620 controls the amount of cleaning water supplied to the drain trap 100 in each step described above.
The control unit 620 controls the amount of cleaning water supplied to the drain trap 100 by controlling the instantaneous flow rate of water discharged from the water discharge unit 610, for example.
Or the control part 620 makes constant the instantaneous flow volume of the water discharged from the water discharging part 610 in each process, and controls the direction of the water discharged by the water discharging part 610, etc., to the drain trap 100 in each process. The supply amount of cleaning water may be controlled. As an example, the control unit 620 changes the discharge direction of water from a position away from the drain outlet 521 of the washing floor 520 toward a position close to the drain outlet 521 in the sedimentation soil discharging process, so that each part of the washing floor 520 The water discharged to the water flows into the drain trap 100 at substantially the same timing, and a large amount of washing water can be supplied to the drain trap 100.

Further, the cleaning water supplied to the drain trap 100 may be tap water or sterilized water. Alternatively, it may be a mixed water of tap water and sterilized water. By using the sterilized water, the propagation of bacteria in the drain trap 100 can be suppressed.
Although the temperature of the washing water is arbitrary, by using hot water, sebum and the like adhering to the sealing wall 120 and the inner wall surface of the trap body 110 are likely to float on the water, and dirt in the drain trap 100 is easily discharged.

As described above, the drain trap cleaning system according to the present embodiment includes the drain trap 100 and the drain trap cleaning device 600. Then, the control unit 620 executes a floating dirt discharge process for supplying a small flow rate of cleaning water after executing a sediment dirt discharge process for supplying a large flow rate of cleaning water.
In the settled dirt discharging step, the floating dirt inside the sealed water cylinder 120 is flowed to the outside of the sealed water bottle 120, and the precipitated dirt precipitated in the drain trap 100 is discharged out of the drain trap 100. In the subsequent floating dirt discharge step, the floating dirt floating in the drain trap 100 is discharged outside the drain trap 100.
For this reason, according to the present embodiment, it is possible to efficiently discharge both the settled dirt and the floating dirt in the drain trap 100 to the outside of the drain trap 100.

Further, in the drain trap cleaning system according to the present embodiment, in particular, a water outlet 181 is formed in the side portion of the trap body 110, and is opened downward between the water inlet 180 (bent portion 112) and the sealing cylinder 120. This is effective for the drain trap 100 in which the concave stagnation portion is formed.
In such a drain trap 100, when a large amount of washing water is supplied to the drain trap 100, floating dirt enters the stagnation part as shown in FIG. 5B, and between the stagnation part and the water outlet 181. The wall surface of the trap body 110 (such as the bent portion 112) prevents floating dirt from flowing toward the water outlet 181.
However, according to the drain trap cleaning system according to the present embodiment, since the suspended dirt discharging step is performed with a small flow of washing water after the settled dirt discharging step, the floating dirt remaining in the stagnation portion is directed to the outlet 181. And drained out of the drain trap 100.

Further, in the settled dirt discharging step, it is desirable to supply cleaning water to the drain trap 100 so that the water level of the water W in the drain trap 100 is located in the stagnation part. By supplying the cleaning water so that the water level of the water W is located in the stagnation part, the cleaning water is sufficiently supplied to the drain trap 100, the sediment dirt is efficiently discharged, and the replacement rate of the sealed water is increased. be able to.
In the floating dirt discharging step, it is desirable to supply cleaning water to the drain trap 100 so that the water level of the water W in the drain trap 100 is lower than the stagnation part. This is because the floating dirt remaining in the stagnation part easily flows toward the water outlet 181 without being caught by the bent part 112 by lowering the water level of the water W to a position lower than the stagnation part.

In addition, while performing the floating dirt discharge process continuously after the sediment dirt discharge process, the water level of the water W may be lowered to a position lower than the stagnation part. Even in this case, it is difficult for the floating dirt to be discharged while the water level of the water W is in the stagnation part, but the floating dirt is discharged from the water outlet 181 after the water level is lowered to a position lower than the stagnation part.
However, in order to discharge floating dirt with less cleaning water, it is desirable to execute the floating dirt discharging step after the water level of the water W is lower than the stagnation part. For this reason, a water-reducing step for reducing the amount of cleaning water supplied to the drainage trap 100 is performed between the settled soil discharging step and the floating soil discharging step, and the water level of the water W is lower than that of the stagnation portion. It is desirable to lower it to a position.
The time of the water reduction process is shorter than the time of the sediment dirt discharging process, for example. This is because the water reduction step is performed for the purpose of lowering the water level of the water W and does not require a long time.

Further, the supply amount of cleaning water is smaller in the floating dirt discharging process than in the settled dirt discharging process. For this reason, in order to sufficiently discharge the floating dirt to the outside of the drainage trap 100, it is desirable that the washing water is supplied to the drainage trap 100 in the floating dirt discharge process for a longer time than the precipitation dirt discharge process. . In this way, more floating dirt in the drain trap 100 can be discharged out of the drain trap 100.
In the adhered dirt removing process, the cleaning water is supplied to the drain trap 100 over the same time as or shorter than the settled dirt discharging process. This is because the adhering dirt removal step is performed for the purpose of raising the water level of the water W and removing the floating dirt adhering to the wall surface from the wall surface to make it float.

Depending on the environment in which the drain trap 100 is provided, the water level of the water W becomes too high in the floating dirt discharging step and may be located in the stagnation part. For this reason, it is desirable that the control unit 620 is configured to be able to change the flow rate of the cleaning water supplied to the drain trap 100 in the floating dirt discharging step. By doing so, it becomes possible to efficiently discharge floating dirt regardless of the environment in which the floating drainage trap 100 is provided.
The control unit 620 may further be configured to be able to change the flow rate of the cleaning water supplied to the drain trap 100 in the settled dirt discharging process and the attached dirt removing process.

  In the example illustrated in FIG. 1, the water discharger 610 is provided below the counter 530, but the position of the water discharger 610 can be changed as appropriate. For example, the water discharger 610 may be connected to the drain trap 100 so that the cleaning water can be supplied directly toward the water inlet 180 without going through the washing floor 520.

It is also possible to discharge the settled dirt by executing the floated dirt discharging process and then executing the settled dirt discharging process after discharging the floated dirt. However, in this case, the floating dirt inside the sealing tube 120 does not flow outside in the previous floating dirt discharging process, but flows outside in the subsequent settled dirt discharging process. For this reason, the floating dirt in the drain trap 100 cannot be efficiently discharged.
That is, as shown in FIGS. 5 to 7, it is possible to efficiently discharge the floating dirt inside the sealed water cylinder 120 by performing the floating dirt discharging process after performing the settled dirt discharging process. .

The embodiment of the present invention has been described above. However, the present invention is not limited to these descriptions.
