Description

Detailed Description of the Invention

  The present invention provides a flushing urinal with a simple structure and control by means of a centrifugal separator for switching the flow path of a circulating urinal having a structure for switching between disposal and recovery, and storing water in the circulating urinal The tank has a strainer that is easy to clean and prevents hair and foreign matter from entering the tank. In addition, the chemical pump that generates sterilized deodorized water is made non-powered by using water pressure, and even if the amount of washing water is saved, urinary stones are generated. In addition, the present invention relates to a water-saving urinal for men that is circulated and washed in order to perform toilet flushing sufficiently.

  Conventionally, the amount of washing water for men's water-saving urinals on the market is about 1.2 liters per time, but depending on the installation site, dirt and bad smell of toilet bowls due to urine stones may drift in the toilet. As a result, the amount of water is often 2 liters or more. There are several factors for urine stone formation, but the main cause is that as the temperature rises and time elapses, the pH value of urine and tap water rises, the dissolution of calcium exceeds the saturation state, and the calcium compound precipitates. It adheres and accumulates. The recent increase in social needs for reducing CO2 has attracted attention for saving water in urinals.

  Therefore, some toilet manufacturers have put the wash water into hypochlorous acid water by electrolysis and put it into practical use in the urinal. However, the electrolysis method is not burdened with maintenance, but has a drawback that it is difficult to obtain high sterilization power. On the other hand, a method of sterilizing and deodorizing with a chemical solution has also been proposed. Although the chemical solution method places a burden on the supply, depending on the effectiveness of the chemical solution, it has a feature that makes it easy to save water.

  In the chemical solution system, for example, a chemical solution injection device for a flush urinal that adjusts the amount of chemical solution from a chemical solution supply unit including a chemical solution container and a supply container and the amount of water from a water supply pipe by controlling an on-off valve (patented) Reference 1), tap water and chemicals are mixed in a hydraulic cylinder, and hypochlorous acid water is used as cleaning water (see Patent Document 4).

  Circulation flush toilets for men that circulate wash water collect the wash water after washing the toilet bowl inside the storage tank and reuse it. (See Patent Document 5) and the like have been proposed for the strainer and the like.

  In addition, men's circulation flush toilets that circulate wash water have a switching valve at the toilet drain outlet, and the direction of the valve is usually led to the direction of draining urine and waste water, but at the time of recovery to the tank An example has been proposed in which the valve direction is switched and water is introduced to the tank side (see Patent Document 2). A switching valve structure for the washing water flow path (see Patent Document 5) has also been proposed.

JP 2003-155768 A Japanese Patent No. 3853825 Japanese Patent No. 5126740 JP 2013-241767 A JP 2014-70374 A JP 2014-84619 A

Hasepper Giken Co., Ltd. (http://www.haccper.co.jp/index.html) McKinley Co., Ltd. (http://cela-mckinley.jp/)

  However, in the technique described in Patent Document 1 described above, in the flush toilet, the drug solution supply unit of the drug solution injection device requires a pump power supply in addition to the drug solution container and the supply container, and controls the opening and closing of the on-off valve. Since an independent control device is required, there is a problem that the entire device becomes complicated and costs increase.

  In addition, since the technique described in Patent Document 3 and Patent Document 4 is a method in which the apparatus is directly connected to the toilet cleaning nozzle to discharge water, the sterilized deodorized water stored in the circulation water storage tank as in the present invention. Is not a technology that uses water for cleaning water.

  Moreover, in the technique of patent document 5, since the desorption hole which takes in and out a strainer must be provided in a toilet bowl, in addition to spoiling a toilet bowl design, there exists a possibility of the water leak from a water storage tank, and cost is too expensive.

  Further, in the techniques described in Patent Document 2 and Patent Document 5, the switching valve opening / closing mechanism and its control tend to be complicated, and the wetted part tends to wear out, so that problems such as water leakage are likely to occur. There was a drawback.

  Furthermore, the techniques described in Non-Patent Document 1 and Non-Patent Document 2 have problems that the device for generating sterilized deodorized water is complicated and large, and is expensive.

  The present invention has been made to solve the above-described problems, and provides a water-saving urinal for men that can be simplified and reduced in cost.

  In the circulation type urinal, the flow path is switched by using a centrifugal switching switch instead of the switching valve for switching the flow path of urine, waste water and recovered water to the water storage tank. The centrifuge switch is a rotation provided at the center of the container divided into an inner circle container part and an outer circle container part through a porous strainer (removal of foreign matter such as body hair) below the toilet bowl drain of the urinal. It is a structure in which the recovered water is splashed off by centrifugal force with a fan.

  While the rotary fan is stopped, urine and waste water are dropped on the inner circular container part while being dropped on the upper surface of the stopped rotary fan via the strainer and discarded from the connected drain pipe. Next, when it collects as circulating water, by rotating a rotary fan, it jumps off to an outer circle container part by centrifugal force, and is collect | recovered in a tank. Further, the centrifugal switching device and the water storage tank are made the same container for cost reduction.

  In addition, the present invention is characterized by having a strainer that can be easily put in and out of the toilet bowl drainage outlet and can reduce the work load during cleaning as a measure for preventing body hair and foreign matters from entering the water storage tank.

  In addition, the present invention uses a chemical solution in order to prevent the formation and adhesion of urine stone and bad odor accompanying water saving. A chemical pump that supplies a small amount of the chemical liquid has a non-powered chemical pump that uses water pressure as a power source.

  Further, the first chemical liquid supplied by the chemical liquid pump contains sodium hypochlorite, and the second chemical liquid contains hydrochloric acid.

  Water passes through the first chemical pump or the second chemical pump connected to the water supply pipe via an electromagnetic valve, but the water pressure inside the water supply pipe is generated when the water is discharged by restricting the valve at the opening. Ascending, the piston of the hydraulic cylinder can be moved forward and backward with the thrust of the hydraulic cylinder and the return coil spring, and a chemical syringe connected with a check valve structure capable of suction and discharge is provided. Two chemicals and water are mixed and discharged into the water storage tank as sterilizing deodorant water. Since the chemical syringe sucks in the chemical liquid when returning by the restoring force of the spring and discharges it when the water pressure is applied, it is possible to easily generate sterilized deodorized water simply by controlling the opening and closing of the water supply with the electromagnetic valve.

  According to the present invention, in a circulatory urinal, a low-cost trouble can be achieved by switching the urine, waste water and recovered water to a centrifugal separation switch integrated with a water storage tank with a simple structure and control. It can be a circulatory water-saving urinal with little.

  In addition, a porous strainer is provided above the centrifugal separator, and when the strainer is clogged due to body hair or foreign matter, the toilet bowl drainage mouthpiece is removed and the toilet bowl drainage hole is opened. Since the hair and foreign matters can be removed from the body and cleaned, the strainer can be easily cleaned.

  In addition, in order to make the pre-wash water to be discarded after washing and the main wash water to be recovered and used almost repeatedly as a powerful sterilization deodorant water, a chemical solution that generates sterilization deodorant water using a chemical solution in the urinal By using the pressure of the water supplied into the water storage tank as the power source of the chemical pump that has a pump and supplies the chemical liquid, a small amount of chemical liquid is supplied without requiring a special drive source and control. Sterilizing and deodorizing by using a chemical solution, a second chemical solution, and water, producing hypochlorous acid water with strong sterilizing power at a low cost, while suppressing the occurrence of urinary stones and bad odor. Water saving is possible.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  First, as shown in FIGS. 1 to 5, the water-saving urinal 1 for men of the present invention is regarded as being in use while the human sensor 4 of the toilet body 5 senses the user. When urine flows downward from the toilet bowl drain port 6 of the toilet body 5, hair, foreign matter, etc. are released from the porous water passage holes of the strainer 8 of the centrifugal separator 7 located below the toilet bowl drain port 6. It is removed and falls onto the rotating fan 17 that is stopped.

  The urine dropped on the rotary fan 17 naturally falls on the inner circular container part 7 b of the centrifugal separation switching container 7 along the outer peripheral surface 17 a of the rotary fan 17. At this time, the porous water passage holes of the strainer 8 are within the perforated area 16 and the partition part 7a with the outer circular container part 7c is wider than the perforated area 16 of the strainer 8, so that the outer circular container part 7c The odor shielding plate 18 is pushed down from the urine outlet 7d connected to the inner circular container portion 7b and is drained from the drain duct pipe 19 as in the drainage path 19a.

  When the user who has finished the service leaves the sensor 4 outside the detection of the human sensor 4, the sterilized deodorized water 23 stored in the water storage tank 9 is supplied with a flow rate accurately controlled by the flow meter 10 through the suction pipe 11. The circulation pump 12 connected to the water is discharged from the washing nozzle 15 through the water supply pipe 13 and the water supply path 14 to preclean the inside of the toilet. In order to reduce the cost, the flow management is a little rough, but there is a method of controlling by a timer without using the flow meter 10.

  As in the case of the urine, the sterilizing and deodorizing water 23 flows down from the toilet bowl drain 6 of the toilet body 5, and the strainer 8 of the centrifugal separator 7 located below the toilet bowl drain 6. From the porous water passage hole, hair, foreign matter, etc. are removed and dropped onto the rotating fan 17 that is stopped.

  As in the case of the urine, the sterilized deodorized water 23 dropped on the rotary fan 17 naturally falls on the inner circular container part 7b of the centrifugal separation switching container 7 along the outer peripheral surface 17a of the rotary fan 17. At this time, the porous water passage hole of the strainer 8 has a perforation area of 16 or less, and since the partition part 7a with the outer circle container part 7c is wider than the perforation area 16, it does not enter the outer circle container part 7c. The odor shielding plate 18 is pushed down from the urine outlet 7d connected to the container part 7b, and drained from the drain duct pipe 19 as in the drainage path 19a.

  When the preliminary cleaning is completed, the rotary fan 17 transmitted to the motor 25 of the centrifugal separator 7 is rotated and the circulation pump 12 is operated, so that the sterilized deodorized water 23 stored in the water storage tank 9 is converted into the flow meter 10. The flow rate accurately controlled by the circulator 12 is discharged from the cleaning nozzle 15 through the water supply pipe 14 by the circulation pump 12 connected to the suction pipe 11, and the inside of the toilet is cleaned. The flow rate at this time does not need to be particularly accurately managed by the flow meter 10 for the purpose of recovery, and may be controlled by a timer.

  Further, since the sterilizing and deodorizing water 23 is collected without being discarded, when the water flows downward from the toilet bowl drain 6 of the toilet body 5, the porous passage of the strainer 8 located below the toilet bowl drain 6 is used. Hair, foreign matter, etc. are removed from the water hole and fall onto the rotating fan 17 rotating as in the rotating direction 17b. The sterilized deodorized water 23 dropped on the rotary fan 17 is bounced off in the direction of the outer circular container part 7c of the centrifugal separation switching container 7 by the centrifugal force of the rotary fan 17 and falls. The sterilized deodorized water 23 that has fallen into the outer circular container part 7 c is collected in the water storage tank 9 as the water flow direction 21 through the tank flow path 20 connected to the centrifugal separator 7 and the water storage tank 9.

  In the water storage tank 9, the sterilized deodorized water 23 discarded in the preliminary cleaning decreases with each use, so that when the float switch 22 for controlling the liquid amount decreases to the operating point level of the float switch B 22 b, the solenoid valve 31 opens. Then, new sterilized deodorized water is taken from the water intake 9 a of the water storage tank 9. When the sterilization deodorant water level 24 of the sterilization deodorant water 23 in the water storage tank 9 reaches the float switch A22a operating point level, the solenoid valve 31 is closed.

  Next, the strainer of the present invention will be described with reference to FIGS.

  Circulating urinals are collected in a water storage tank in order to reuse the wash water after washing the inner surface of the toilet bowl. At that time, body hair, foreign matter, and the like are also mixed. When the hair is reused, the mixed hair erupting from the washing nozzle gives an unsanitary impression and causes clogging in the water channel. Therefore, the circulation type urinal is particularly asked whether the strainer is good or bad. Furthermore, even if a good strainer collects without missing hair, foreign matter, etc., if the subsequent cleaning is troublesome, the frequency of cleaning will be reduced and the strainer will be clogged, and a simple cleaning method is required.

  The strainer 8 shown in FIG. 1 to FIG. 3 is located between the lower part of the toilet bowl drain 6 and the rotary fan 17 for the purpose of preventing body hair and foreign matter from entering the water storage tank 9. And at the time of cleaning, it has to be carried out from a small opening of the toilet bowl drainage port 6 and there is a difficulty that it is difficult to work. Considering the efficiency of the work, the work is easy if the porous area of the strainer 8 is about the area of the opening of the toilet bowl drainage port 6. On the other hand, the strainer 8 is easily clogged and the drainage speed tends to slow down. The larger the porous area of 8, the better the drainage rate. Therefore, it is desirable to increase the efficiency of the cleaning operation while increasing the porous area of the strainer 8.

  In view of this, the strainer according to the present invention is provided with a handle 27 that makes it easy to put in and out of the hole of the toilet bowl drainage port 6 in the soft body strainer 26 in which a soft material that can be expanded and contracted is made porous above the strainer 8. 6 and 7 (a figure), but it is a flexible body strainer that is stretched and folded as shown in FIG. 7 (b figure) by taking advantage of the flexibility of the soft material when attached or removed. Put in and out while expanding and contracting as in 26a. Then, the soft body strainer 26 after being completely attached returns to the original shape of FIGS. 6 and 7 (a diagram) as shown in FIG. 7 (c diagram). When implementing the strainer according to the present invention, the purpose of the strainer 8 is to be a cradle for the strainer according to the present invention.

  Further, by providing the strainer according to the present invention in the same body as the eye plate that covers the toilet bowl drain port 6, it is possible to improve the efficiency of taking in and out.

  Next, with reference to FIGS. 8 to 9, the sterilized deodorized water generating apparatus according to the first embodiment used in the water-saving urinal for men of the present invention will be described in detail.

  In the first embodiment, a syringe cylinder that inhales and discharges a chemical solution and a chemical solution syringe rod are used in a syringe product that is sold in the market. Here, FIG. 8 is a sectional view showing a standby state in which water is not supplied into the cylinder cylinder in the two sets of chemical pumps. FIG. 9 is a cross-sectional view showing a state in which water is supplied into the cylinder cylinder to generate sterilized deodorized water.

  The first chemical liquid pump 33 and the second chemical liquid pump 51 have the same structure. However, the case where the single chemical liquid pump 33 is used as a target for a single function effect such as malodor countermeasures, and the first chemical liquid pump. 33 and the second chemical pump 51 are connected in series or in parallel, and water, sodium hypochlorite and hydrochloric acid are mixed to produce a hypochlorous acid water capable of powerful sterilization and deodorization. You can choose.

  When the electromagnetic valve 31 of the sterilizing and deodorizing water generating device 30 is closed (standby state), the water pressure in the water supply facility 32 is completely absent, so the first piston 35 is restored by the repulsive force of the first cylinder coil spring 36. Return to the position. Accordingly, the first chemical liquid syringe rod 43 that sucks and discharges the chemical liquid in the first syringe cylinder 42 is returned to the original position by the repulsive force of the first syringe coil spring 44. At that time, the first chemical liquid in the first chemical liquid container 37 is sucked into the first syringe cylinder 42 through the first check valve A40 and the first three-way port adapter 41 in the first liquid feeding direction A39. It stays and accumulates and waits for the next discharge.

The second syringe coil spring 62 that returns when the water pressure in the second cylinder cylinder 52 is lost is provided around the second chemical liquid syringe rod 61 provided and is urged upward.

  Similar to the first chemical liquid pump 33, when the electromagnetic valve 31 of the sterilizing and deodorizing water generating device 30 is closed (standby state), the water pressure in the water supply facility 32 is completely zero, so the second piston 53 Is restored to the original position by the repulsive force of the second cylinder coil spring 54. Along with this, the second chemical liquid syringe rod 61 that sucks and discharges the chemical liquid in the second syringe cylinder 60 returns to the original position by the repulsive force of the second syringe coil spring 62. At that time, the second chemical liquid in the second chemical liquid container 55 is sucked into the second syringe cylinder 60 through the second check valve A58 and the second three-way port adapter 59 in the second liquid feeding direction A57. It stays and accumulates and waits for the next discharge.

  The first chemical pump 33 in a state where the sterilized deodorized water generating device 30 according to the first embodiment of the present invention generates sterilized deodorized water will be described with reference to FIG.

  When the electromagnetic valve 31 is opened from the water supply port 2 with a water pressure of about 0.2 to 0.74 Mpa, the water is supplied to the first chemical liquid pump 33, the second chemical liquid pump 51, the valve 68, and the mixer via the water supply equipment 32. After 50, the water is injected into the storage tank 9. At that time, if the amount of water discharged from the valve 68 is limited by adjusting the valve 68, the water pressure in the water supply facility 32 increases. Using this rising pressure, the piston in the cylinder can be moved forward and backward. The mixer 50 is not particularly required when the chemical solution is directly fed into the water storage tank 9.

  When the water pressure in the water supply facility 32 rises, the first piston 35 compresses the first cylinder coil spring 36 and pushes it to the position of the first hydraulic cylinder stopper 34a. At that time, the first piston abutting surface 35a of the first piston 35 is connected to the first syringe rod head 43a of the first chemical liquid syringe rod 43 that sucks and discharges the chemical liquid in the first syringe cylinder 42. By being able to advance and retreat by contacting, the first syringe coil spring 44 is compressed, and the first check valve B49 is connected via the first three-way adapter 41 and the first liquid feeding pipe B47. The first chemical solution in the first chemical solution container 37 is fed to the mixer 50 in the first liquid feeding direction B48.

The second syringe coil spring 62 is compressed, and the second check valve B67 is connected via the second three-way adapter 59 and the second liquid feeding pipe B65. Then, the second chemical solution in the second chemical solution container 55 is fed to the mixer 50 in the second liquid feeding direction B66. In addition, the mixer 50 can be omitted and the liquid can be directly fed into the water storage tank 9 via the second liquid feeding pipe B65.

  The chemical liquid amount adjustment of the first chemical liquid pump 33 and the second chemical liquid pump 52 will be described.

  It is possible to adjust the amount of the chemical solution in consideration of the case where the consumption amounts of the two chemical solutions are not the same amount or corresponding to the change in the concentration of the chemical solution. A screw having a length suitable for the adjustment range is applied to the outer diameter portion of the first cylinder tube 34 or the second cylinder tube 52 and the inner diameter portion of the first syringe holder 45 or the second syringe holder 63, By fixing the first adjustment nut 46 or the second adjustment nut 64 at an arbitrary position, the space between the second piston abutting surface 53a and the second syringe rod head 61a is changed, and the suction of the chemical solution is performed. And emissions change.

The second chemical pump 84 and the valve 68 are connected to the mixer 50. The valve 68 can be adjusted to a pressure balance that allows the first chemical pump 71 and the second chemical pump 84 to operate according to the feed water pressure. The mixer 50 is not particularly required when the chemical solution is directly fed into the water storage tank 9.

  The first chemical pump 71 includes a water supply port 2, a first cylinder cylinder 76 connected to the water supply facility 32 via the electromagnetic valve 31, and a first piston 77 that can advance and retreat in the first cylinder cylinder 76. When the water pressure in the first cylinder cylinder 76 is lost, the first piston 77 is urged upward by the first cylinder coil spring 78 provided around the first piston 77.

After 50, the water is ejected into the water storage tank 9. At that time, if the amount of water discharged from the valve 68 is limited by adjusting the valve 68, the water pressure in the water supply facility 32 increases. Using this rising pressure, the piston in the cylinder cylinder can be advanced and retracted. The mixer 50 is not particularly required when the chemical solution is directly fed into the water storage tank 9.

  When the water pressure in the water supply facility 32 rises, the first piston 77 compresses the first cylinder coil spring 78 and moves to a position where the first stopper fixing nut 75 contacts the first waterproof lid 73. The amount of movement of the piston becomes the amount of discharged chemical liquid. At this time, the first chemical liquid syringe rod 77 a attached to the first piston 77 in the first cylinder cylinder 76 is stored in the first syringe cylinder 79. The first chemical liquid in the first chemical liquid container 37 in the liquid is fed from the first check valve A81 to the mixer 50 through the first liquid feeding pipe B47 in the first liquid feeding direction B82. It is also possible to send the liquid directly into the water storage tank 9 without the mixer 50.

  Next, the 2nd chemical | medical solution pump 84 in the state which the sterilization deodorizing water production | generation apparatus 70 by the 2nd Embodiment of this invention produces | generates sterilization deodorizing water is demonstrated in FIG.

  Similar to the first chemical pump 71, when the water pressure in the water supply facility 32 rises, the second piston 90 compresses the second cylinder coil spring 91, and the second stopper fixing nut 88 becomes the first stopper. It moves to a position where it comes into contact with the waterproof lid 86. The amount of movement of the piston becomes the amount of discharged chemical liquid. At this time, the second chemical liquid syringe rod 90 a attached to the second piston 90 in the second cylinder cylinder 89 is stored in the second syringe cylinder 92. The 2nd chemical | medical solution of the 2nd chemical | medical solution container 55 in a liquid is sent to the mixer 50 through 2nd liquid feeding pipe | tube B65 from 2nd non-return valve A96 in the 2nd liquid feeding direction B95. It is also possible to send the liquid directly into the water storage tank 9 without the mixer 50.

  The chemical liquid amount adjustment of the first chemical liquid pump 71 and the second chemical liquid pump 84 will be described.

  It is possible to adjust the amount of the chemical solution in consideration of the case where the consumption amounts of the two chemical solutions are not the same amount or corresponding to the change in the concentration of the chemical solution. The first piston 77 or the second piston 90 is provided with a first screw 77b or a second screw 90b for adjusting the liquid amount. The first waterproof lid 73 attached to the first cylinder head 72 or the second cylinder head 85, or the second waterproof lid 86 and the first stopper fixing nut 75, or the second stopper. The space of the fixing nut 88 becomes the amount of movement of each piston, and the amount of suction and discharge of the chemical solution changes.
