Description

  The present invention relates to a urinal system and a method for cleaning the urinal system.

  The calcium content in the urine is changed into a component that does not dissolve in water due to the action of bacteria, and the rot organic matter is mixed with this in a complex manner, so that it firmly adheres to the urinal drainage pipe system as a scale (urite). Especially in places where many urinals are installed, such as hotels, office buildings, department stores, stations, etc., each urinal is connected to a common horizontal pipe installed under the floor slab. The wastewater is led to the drainage pipe through. However, since the gradient of the horizontal pulling tube is about 1/50 to 1/100, the amount of urine stone attached is large in the horizontal pulling tube up to the drainage tub in the urinal drainage pipe system. Conventionally, urinal drainage pipes and other urinal drainage pipes have been washed by supplying high-pressure washing water and peeling off adhering urine from the inner wall of the drainage pipe by water pressure, or in addition to this. It is cleaned by supplying chemicals for tube cleaning, which dissolves urine stone, and chemicals with high bactericidal effect (sterilized water).

  However, in recent years, the amount of water supplied per urinal has decreased from the previous 3.5 to 5 liters to about 1 to 2 liters due to the saving of washing water. For this reason, in addition to an increase in the amount of urine stone in the horizontal pulling tube, foreign matter such as body hair does not flow and often remains in the horizontal pulling tube.

  In view of this point, in Patent Document 1, a tank for storing washing water is disposed upstream of the urinal, and an outlet pipe of the tank is connected to a horizontal pulling pipe. A technique is disclosed in which washing water is discharged from a tank to a horizontal pulling pipe at a low nighttime, and foreign matter is caused to flow by the flow. In addition, Patent Document 1 discloses that sterilizing water is allowed to flow after water discharge as necessary.

JP 2010-121276 A

  In Patent Document 1, tap water (clean water) is used as cleaning water. It is prohibited by law to connect the water supply pipe that supplies clean water directly to the horizontal pipe because there is a risk of backflow even if it goes through a valve. Therefore, in patent document 1, it is set as the structure which arrange | positions a tank between both, temporarily stores clean water (washing water) in a tank, and discharges the stored clean water (cleaning water) to a horizontal draw pipe. However, providing such a tank complicates the equipment and increases the installation cost.

  On the other hand, in the case of the water-saving type, since the amount of washing water is small, urine does not dilute even if it is washed with washing water, and it flows to the horizontal draw tube with a high concentration. The trap between the urinal and the horizontal pipe cannot be made too large because the amount of washing water is small. Moreover, since the amount of washing water is small, high-concentration urine tends to stay in the horizontal pulling tube. Due to these factors, the water-saving urinal system not only tends to clog the drain pipe system, but also has room for improvement in terms of odor. In view of this point, Patent Document 1 proposes flowing clean water directly into a horizontal pulling tube and then flowing sterilized water directly. However, providing the above-described tank and providing such a facility for supplying sterilizing water leads to a complicated structure and an increased cost. On the other hand, in a conventional urinal system that is not a water-saving type, about 0.5 liters of washing water always accumulates in the trap between the urinal and the horizontal pulling tube. Therefore, if the urine is surely washed away and sealed in the trap, and the chemical solution is poured into the urinal together with the washing water, the chemical solution stays in the trap together with the washing water, and a predetermined sterilizing effect can be expected.

  The present invention has been made in view of the above, and does not require a tank for cleaning the horizontal pulling tube, and can have a simple configuration. Desirably, even when the chemical solution is supplied together with the cleaning water flowing to the urinal, It is an object of the present invention to provide a urinal system that can be expected to have a predetermined chemical effect and that is particularly suitable as a water-saving type, and a cleaning method for the urinal system.

  In order to solve the above-mentioned problems, a urinal system of the present invention is a urinal system comprising a urinal and a horizontal pulling pipe to which a drainage part of the urinal is connected and through which drainage passes through the urinal. A wash water supply pipe that supplies middle water as wash water to the urinal, a bypass pipe that connects the lateral pulling pipe and the wash water supply pipe, and a valve mechanism provided in the bypass pipe. Then, the intermediate water can be directly supplied from the washing water supply pipe to the horizontal pipe through the bypass pipe by opening the valve mechanism.

  The bypass pipe is preferably connected to the upstream side of the urinal connected to the most upstream side of the horizontal pulling pipe. It is preferable that chemical solution supply means for supplying a chemical solution to the horizontal pulling tube is provided downstream of the valve mechanism provided in the bypass tube. The washing water supply pipe is preferably provided with a chemical solution supply means for supplying a chemical solution to the urinal. It is preferable that a drainage retention means capable of temporarily retaining a part of the drainage containing the chemical liquid flowing in the lateral pulling pipe is provided in the horizontal pulling pipe. The drainage retention means is disposed on the further downstream side of the urinal connected to the most downstream side of the horizontal pulling pipe, and a normal time path through which drainage flowing through the horizontal pulling pipe normally passes. It is preferable to have a residence time path that passes when the wastewater stays.

  The cleaning method of the urinal system of the present invention is to supply the urinal to the urinal from the rinsing water supply pipe and wash the urinal, and to discharge the effluent that has passed through each urinal to the horizontal pipe. In the cleaning and draining method in the urinal system used, the middle water flowing through the cleaning water supply pipe is directly supplied to the horizontal pulling pipe at a predetermined timing in order to remove foreign matters in the horizontal pulling pipe. .

  The urinal system has a bypass pipe connecting the horizontal pulling pipe and the washing water supply pipe, and a valve mechanism provided in the bypass pipe, and the bypass pipe is included in the horizontal pulling pipe. Connected to the upstream side of the urinal connected at its most upstream side, and opens the valve mechanism to connect the middle water via the bypass pipe at the most upstream side. It is preferable to supply from the further upstream side of the urinal. It is preferable to supply a chemical | medical solution to the said horizontal draw pipe through the said bypass pipe at predetermined timing. Moreover, it can also be set as the structure which supplies a chemical | medical solution to the said urinal via the said washing water supply pipe | tube at predetermined timing. It is preferable that a part of the waste water containing the chemical liquid flowing in the horizontal pipe is temporarily retained.

  The present invention is configured to supply middle water as washing water for washing the urinal. As a result, the wash water supply pipe for supplying the intermediate water and the horizontal pipe are directly connected by the bypass pipe, and a predetermined amount of the intermediate water is caused to flow directly into the horizontal pipe at an appropriate timing. Foreign matter such as body hair accumulated in can be discharged. In addition, in order to supply the middle water to the horizontal pipe, a configuration in which a valve mechanism is interposed in the bypass pipe is required, and it is not necessary to dispose a tank in the middle. it can.

In addition, it is preferable that a chemical solution having a high urinary stone adhesion prevention effect and a bactericidal effect is supplied through the bypass tube, and the urinary stone adhesion to the horizontal pulling tube can be prevented by the chemical solution effect. In the conventional urinal system, the chemical solution is only supplied to the urinal. However, according to the present invention, the chemical solution can be supplied directly to the horizontal pulling tube via the bypass tube, and a high chemical effect can be obtained. Therefore, the present invention is suitable for solving the problem of the water-saving urinal system at an early stage that the horizontal pulling tube is clogged due to adhesion of foreign matters or urine stones, or a strange odor drifts. Of course, means for supplying a chemical solution from the washing water supply pipe to the urinal may be used in combination.
Further, by providing a drainage retention means capable of temporarily retaining part of the drainage flowing in the horizontal pipe, the wastewater containing the chemical solution supplied as described above is temporarily stored in the horizontal pipe. It can be retained, and the effect of preventing urinary stones adhering to the horizontal pulling tube and the sterilizing effect can be further enhanced by the chemical effect.

FIG. 1 is a schematic diagram showing an outline of a urinal system according to an embodiment of the present invention. FIG. 2 is a view for explaining the structure of a trap of a urinal. FIG. 3 is a view for explaining an example of the drainage retention means.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a schematic configuration of a urinal system according to the present embodiment. As shown in this figure, for example, in this embodiment, first, the urinals 10-12 are arrange | positioned in parallel with the wall surface. A flush water supply pipe 20 is connected to each of the urinals 10 to 12, and the flush water is supplied to each of the urinals 10 to 12 through the flush water supply pipe 20 by the operation of the flush valves 10a to 12a. The The washing water supply pipe 20 is connected to a supply source of middle water (reused water for wastewater) and supplies middle water.

  Each of the urinals 10 to 12 is provided with a chemical solution supplying means for supplying a chemical solution having a high urine stone removing effect and a sterilizing effect. In the present embodiment, as shown in FIG. 1, a chemical liquid supply device (hereinafter referred to as “urinal”) is provided in the washing water supply pipe 20 located further upstream of the urinal 12 installed on the most upstream side. 30) is provided. The urinal chemical liquid supply device 30 includes a chemical liquid storage tank 31, a pump 32, a chemical liquid supply pipe 33 connected to the cleaning water supply pipe 20, and a flow meter 34 that measures the flow rate of the cleaning water flowing in the cleaning water supply pipe 20. The pump 32 operates in accordance with the flow rate of the cleaning water measured by the flow meter 34, and a predetermined amount of chemical liquid is mixed from the chemical liquid storage tank 31 into the cleaning water supply pipe 20 via the chemical liquid supply pipe 33. The This urinal drug supply device 30 can supply a drug solution to all of the urinals 10 to 12, and for example, “Sanitizer MK111” (trade name) manufactured by Nippon Calmic Co., Ltd. can be used.

  The urinal drug supply device 30 is not limited to the one having the above-described configuration. For example, the urinal drug supply device 30 has a structure provided one by one corresponding to the number of urinals 10 to 12 (for example, “Sanitizer MK7” manufactured by Nippon Calmic Co., Ltd. (Product name)) can also be used.

  Each of the urinals 10 to 12 is connected to a urinal drainage pipe system having a horizontal pulling pipe 40 and a drainage pipe 50. The horizontal pipe 40 is laid under a floor slab with a gradient of about 1/50 to 1/100, and a drain pipe 50 is connected to the tip of the horizontal pipe 40.

  Specifically, each of the urinals 10 to 12 is disposed with its drain pipes 10 c to 12 c connected to the horizontal pull pipe 40. As shown in FIG. 2, eyelet type traps 10b to 12b are provided at the drain outlets at the bottom of the urinals 10 to 12, respectively. This is a drain trap that is often used in so-called water-saving urinals 10-12, and since the amount of washing water discharged to each urinal 10-12 is small, the trap 10b- 12b has a small capacity.

  The horizontal pulling tube 40 is preferably provided with drainage retention means 400 as in this embodiment. The drainage retention means 400 is provided further downstream of the urinal connected to the most downstream side of the horizontal pulling pipe 40 (the urinal indicated by reference numeral 10 in FIG. 1). The drainage retention means 400 has a function of temporarily retaining drainage flowing through the horizontal pulling tube 40. As described above, the urinals 10 to 12 are supplied with a chemical solution having a high urine stone adhesion preventing effect and a high bactericidal effect from the urinal chemical solution supply device 30, but in a water-saving urinal system such as this embodiment, a trap is used. Since the capacity of 10b to 12b is small and drained in a short residence time, the chemical effect may not be sufficiently exhibited.

  Therefore, if the wastewater containing the chemical liquid flowing in the horizontal pulling tube 40 is temporarily retained by the drainage retention means 400, the retention time of the chemical liquid becomes long, and the chemical effect can be enhanced. The structure of the drainage retention means 400 is not limited as long as the drainage can be temporarily retained. However, a structure in which drainage is always retained is not preferable because it prevents quick drainage during normal times. The structure must fulfill.

  FIG. 3 shows an example of the drainage retention means 400. The normal time path 410 formed in a straight line and one end 420a communicate with the upstream side of the normal time path 410, and the other end 420b is the normal time path. 410 has a residence time path 420 serving as a detour that communicates downstream from the communication position with the one end 420a in 410. A switching valve 430 is provided between the communication positions of the normal time path 410 and the one end 420a and the other end 420b of the dwell time path 420. Then, the horizontal pulling tube 40 is disposed so that the residence time path 420 is on the upper side. When the switching valve 430 is adjusted in the direction along the normal time path 410 (the direction of the two-dot chain line in FIG. 3), the drainage passes through the normal time path 410, but the switching valve 430 is orthogonal to the normal time path 410. When the direction is adjusted to the direction (the direction of the solid line in FIG. 3), the drainage cannot pass through the normal time path 410 and tries to bypass the stay time path 420. Accordingly, the drainage stays in the horizontal pulling tube 40 until it stops at the switching valve 430 and reaches a height that can be bypassed in the staying path 420. The amount of drainage that can stay in the horizontal pipe 40 varies depending on the angle at which the stay path 420 is arranged when the normal path 410 is centered, and is located immediately above the normal path 410. If the adjustment is performed, the amount of residence is the largest.

  Here, the urinal system of the present embodiment is characterized in that a bypass pipe 60 that directly connects the washing water supply pipe 20 and the horizontal pulling pipe 40 is provided. Specifically, the bypass pipe 60 is connected to the further upstream side of the urinal 12 connected most upstream in the washing water supply pipe 20 and the most upstream side of the horizontal pulling pipe 40. The urinal 12 is connected further upstream, for example, to the upstream end 40 a of the horizontal pulling tube 40. A valve mechanism 61 is interposed in the bypass pipe 60. Therefore, when the valve mechanism 61 is opened, the intermediate water flows from the cleaning water supply pipe 20 to the bypass pipe 60 and further flows to the horizontal pulling pipe 40.

  Further, in the bypass pipe 60, a chemical liquid supply device (hereinafter referred to as “horizontal drawing pipe chemical supply apparatus”) 70 is provided on the downstream side of the valve mechanism 61 as a chemical supply means for supplying a chemical to the horizontal pulling pipe. . The horizontal pulling tube chemical supply device 70 includes a tank 71 for storing a high chemical solution such as a urine stone adhesion preventing effect and a bactericidal effect, a pump 72 for sucking up the chemical solution from the tank 71, and a chemical supply pipe 73 connected to the bypass pipe 60. have. When flowing the middle water through the bypass pipe 60, the chemical liquid is mixed from the horizontal pull pipe chemical supply apparatus 70 at an appropriate timing and is directly supplied to the horizontal pull pipe 40. Therefore, a high chemical effect can be expected.

Next, the operation of this embodiment will be described.
During normal use, the valve mechanism 61 of the bypass pipe 60 is closed. Moreover, when the drainage retention means 400 is provided like this embodiment, the switching valve 430 of the drainage retention means 400 is adjusted so that it may become the direction along the normal time path | route 410, and it is set as the valve opening state. Accordingly, when the urinals 10 to 12 are used and the flush valves 10a to 12a are opened, medium water as wash water is supplied from the wash water supply pipe 20 to the urinals 10 to 12. Note that a predetermined amount of the chemical solution supplied from the urinal chemical solution supply device 30 is mixed in the middle water. The middle water that has flowed through the urinals 10 to 12 is drained from the traps 10 b to 12 b to the horizontal pulling pipe 40 via the drain pipes 10 c to 12 c. The drainage flowing through the horizontal pulling pipe 40 passes through the normal time path 410 of the drainage retention means 400 and is drained to the drainage pipe 50 without being retained. Of course, even in this process during normal use, the above-mentioned chemical solution having the effect of preventing urinary stone adhesion and the bactericidal effect acts.

  At a predetermined timing, for example, the switching valve 430 of the drainage dwelling means 400 is switched in a direction orthogonal to the normal time path 410 (the direction of the solid line in FIG. 3) for a time set by a timer once every several hours. As a result, the waste water flowing in the horizontal pulling tube 40 stops at the switching valve 430 until it flows into the staying path 420 and stays in the horizontal pulling tube 40. As described above, the waste water flowing in the horizontal pulling tube 40 contains the chemical solution having the urine stone adhesion preventing effect and the bactericidal effect, and by this retention, a higher chemical solution effect than in normal use can be obtained.

  Further, the valve mechanism 61 of the bypass pipe 60 is set at a predetermined timing, for example, once every several hours set by a timer in the same manner as described above, or in a time zone where there is almost no user (for example, midnight). Open the valve. At this time, the drainage storage unit 400 switches the normal time path 410 so that drainage can pass.

  By opening the valve mechanism 61, the middle water of the cleaning water supply pipe 20 flows directly from the upstream end 40 a into the horizontal pulling pipe 40 via the bypass pipe 60. As described above, since the water-saving urinal system has a small amount of washing water, foreign matter such as body hair and dust is difficult to flow, and the connection portion 10d between the drain pipes 10a to 12a of the urinals 10 to 12 and the horizontal pulling pipe 40 is provided. In ~ 12d etc., they are often caught and collected. However, according to the present embodiment, since the middle water of the washing water supply pipe 20 can be directly supplied into the horizontal pulling pipe 40 via the bypass pipe 60, the body hair or the like that is caught by the momentum of the flow of the middle water. Foreign matter can be washed away. Thereby, the drainage failure, bad odor, etc. caused by clogging in the horizontal pulling tube 40 can be reduced. In addition, since the cleaning water supply pipe 20 is configured to supply middle water as cleaning water to the last, there is no problem even if it is connected to the horizontal pulling pipe 40 via the bypass pipe 60, and the practicality is also excellent. Yes.

  When flowing the middle water through the bypass pipe 60, the chemical liquid is supplied from the horizontal draw pipe chemical supply apparatus 70 at an appropriate timing. As described above, by flowing the middle water through the bypass pipe 60 vigorously, before or after the step of flushing out the foreign matter remaining in the horizontal pulling pipe 40, or at both timings, the valve mechanism 61 While adjusting the flow rate, a predetermined amount of medium water is passed through the bypass pipe 60. At this time, the chemical solution is supplied from the horizontal pull tube chemical supply device 70. Thereby, the inside of the horizontal pulling tube 40 is sterilized by the chemical solution. In addition, it is preferable to switch the drainage retention means 400 so that it flows to the side of the retention time path 420 also at the timing of supplying the chemical solution from the horizontal pulling tube chemical supply device 70. Thereby, the residence time of a chemical | medical solution becomes long and the higher chemical | medical solution effect can be anticipated.
