Description

  The present invention relates to a water-saving device for flush toilets.

  Conventionally, since many prior literatures are mentioned as a water-saving countermeasure apparatus of a flush toilet, the outline | summary is demonstrated.

  Document (1) is “Structure of an apparatus for supplying hot water remaining in a bathtub to a toilet rotor tank using a home bus pump or the like” of Japanese Patent Application Laid-Open No. 2004-132161. The present invention relates to a facility that promotes water saving in a toilet by feeding water remaining in a bathtub to a toilet rotor tank. When the water level in the toilet rotor tank reaches the set water level of the float switch, the water supply operation is stopped by shutting off the power supply of the pump by the action of the float switch. That is, the stop is caused by the action of the float switch. Therefore, this document (1) does not have water supply at the same time as the remaining water in the bathtub and clean water, is selective use, and is difficult to operate, and the rest of the bathtub as described in the specification [0004]. Installation and removal of hot water pipes are inconvenient.

  Reference (2) is “Water-saving unit and water-saving hot-water supply / remedy system” of Japanese Patent Laid-Open No. 2001-21210. The present invention relates to a water-saving unit and a water-saving hot water supply / remembrance system for reusing residual water in a bathtub for toilet cleaning and washing. The open / close valve on the low tank side is actuated by a timed water stop device (float switch), but stops water supply when the low tank reaches a predetermined water level. Moreover, this water supply stop calculates the amount of water supply, and determines whether the predetermined amount was reached. Therefore, in this document (2), there is no water supply at the same time as the residual water in the bathtub and the clean water, and the residual water in the bathtub is supplied next to the clean water as described in the specification [0053].

  Reference (3) is “Miscellaneous water use device” disclosed in JP-A-11-247254 and JP-A-11-247244. In the present invention, the remaining hot water (tub water) in the bathtub is sent into the water storage tank of the flush toilet, and is used for the flushing water of the flush toilet to save water. An automatic water shut-off device that stops water supply when the water in the water storage tank of the flush toilet reaches a predetermined water level, and a water flow detection means that detects water flow through the water supply path for supplying the water. In addition, the automatic water stop apparatus of water supply is a ball tap in a water storage tank. Therefore, this document (3) temporarily supplies water at the same time as bathtub water and clean water, but as described in [0020], the supply of bathtub water stops before reaching a predetermined water level, and thereafter Supplement with clean water.

  Reference (4) is “a water-saving device for toilets” disclosed in Japanese Patent Laid-Open No. 2005-344490. According to the present invention, when the water level of the toilet cleaning water tank is lowered, the remaining water in the bathtub is sent to the cleaning water tank by the pump and reused as the toilet cleaning water. The water level sensor provided in the toilet flushing water tank operates the pump in the bathtub to supply water to the toilet flushing water tank. Therefore, this reference (4) does not supply water at the same time as the remaining water and clean water in the bathtub, and selects and uses bathtub water and clean water as described in the specification [0009].

  Reference (5) is a “water recycling apparatus” disclosed in Japanese Patent Application Laid-Open No. 2006-83617. According to the present invention, domestic wastewater such as laundry wastewater, washwater wastewater, bathroom wastewater, and kitchen wastewater is purified in a septic tank, and the purified wastewater is reused as toilet wash water. The water level sensor provided in the water storage chamber of the reused water tank main body controls the water supply pump to supply purified waste water to the toilet wash water tank or to stop water supply. Further, although not described, this water supply pump is considered to be turned on and off by a float switch of the washing water tank. Therefore, in the literature (5), there is no water supply at the same time as domestic wastewater and clean water, and selective use of domestic wastewater and clean water as described in the specification [0019].

  Further, Document (6) is “Apparatus for Reusing Bath Water into Toilet Water by Water Flow of Water Supply” in Japanese Patent Application Laid-Open No. 2006-299770. The present invention is a structure for supplying / stopping bath water and clean water by using a float switch provided in a toilet tank. Therefore, in the literature (6), there is no water supply at the same time as bath water and clean water, and the clean water is used when the bath water disappears as described in [Summary].

  Reference (7) is “Effective utilization system of bath remaining hot water or rainwater” of utility model registration No. 3023140. This device is a system that can effectively use the remaining bath water and rain water as washing and toilet water, supply / stop water to the storage tank, start / stop pump, manual switch, and water level of the storage tank This is done with a water level sensor that detects When there is no remaining hot water in this water storage tank, it is structured to supply clean water. Therefore, Document (7) is not a structure that uses the remaining hot water of the bath, rain water and clean water at the same time. And since it depends on the water in the water storage tank, it is conceivable that the use of clean water becomes random, leaving problems in the use of hand-washing.

Reference (8) is “Rainwater Outflow Suppression Reuse Facility” in Utility Model Registration No. 3065271. This device is a rainwater outflow suppression and reuse facility that reuses rainwater as toilet water. And although not explained or illustrated, it is a structure that uses a float switch provided in a toilet tank to supply and stop rainwater and clean water. Therefore, this device is not a structure that uses rainwater and clean water at the same time. And since it depends on the rainwater in this rainwater outflow suppression reuse facility as described in the specification, it is conceivable that the use of clean water becomes random, and there is a problem in the use of hand washing.

  FIG. 1 is an external view of a building in which a water-saving countermeasure device for a flush toilet according to the present invention is installed, FIG. 2 is a perspective view showing an example of a toilet hand-washing table and a toilet, and FIG. 3 is a diagram of a water-saving countermeasure device for a flush toilet according to the present invention. 4 is an enlarged front view showing an example of a control panel, and FIG. 5A is an enlarged view showing an example in which a sensor is installed on a rising wall facing a hand-washing table via a holding tool. 5-2 is an enlarged overhead view showing an example of the relationship between the holding tool and the sensor, and FIG. 5-3 is an enlarged overhead view showing another example of the relationship between the holding tool and the sensor. 6 is an enlarged schematic cross-sectional view of the faucet control device.

  In the figure, reference numeral 1 denotes a second sensor disposed on a hand wash basin C1 of the flush toilet C. The second sensor 1 has a light emitting element provided in the short side direction X of one rising wall C10 of the hand wash basin C1. 100 and a light receiving element 101 having a light receiving portion and a command portion provided in the short-side direction X1 of the other rising wall C11 opposite to this. When light is emitted from the light emitting element 100 toward the light receiving element 101, the light is blocked by running water A flowing down from the hand washing pipe C20 (discharge pipe) of the hand washing stand C1 ( When detected, a command to operate the pump 2 described later is issued from the command unit. Of course, the same applies to the case of being blocked by a hand (not shown). However, in this case, it is desirable to have a structure in which a ball tap of a toilet tank C40, which will be described later, and a determination unit of the control panel 5 are interlocked (to prevent overflow). Y is the longitudinal direction of the rising wall surface C12 of the hand-washing table C1, and light is emitted following the longitudinal direction Y. The light emitting element 100 and the light receiving element 101 may have other structures. For example, the light of the light emitting element 100 is caught by a light receiving portion attached to the light emitting element 100 via a reflector, As will be described later, a structure in which a command is issued from a command unit attached to the light emitting element 100 and the command is input to the control panel 5 is also possible.

  This second sensor 1 (light emitting element 100 and light receiving element 101) has the structure shown in FIGS. 5-1 to 5-3. For example, in FIGS. Thus, the second sensor 1 is provided on the key-shaped holding tool 3, and the short-side direction X between the rising wall surface C10 and the rising wall surface C11 using the holding tool 3 and a stopper (not shown). Although it is detachably provided at an appropriate position of X1, it is set at a location where the running water A can be detected. Then, by providing the gripping tool 3 so as to be movable, the hand wash stand C1 of different sizes, shapes, etc., the rising wall surface C10 of different heights, shapes, etc., or the hand wash tube C20 of different bending angles, shapes, etc., or A structure that can handle the amount and direction of water flow. And in FIG. 5-3, the guide 301 is provided in the top-plate part 300 of the holding tool 3, and it is set as the structure where the 2nd sensor 1 can move along this guide 301, and the transversal direction of the standing wall surface C10 grade | etc., It can be freely moved in the directions of X and X1, and can be adapted to the hand-washing table C1 of different sizes, shapes, etc. as needed. In addition, also in the example of FIGS. 5-3, the position of the 2nd sensor 1 is fixed with the fastener which is not shown in figure.

  Then, as shown in FIG. 3, the second sensor 1, the control panel 5, and the pump 2 are connected via a cable 6. Further, the pump 2 connected to the waste water tank 7 is allowed to face the water receiving surface C30 of the hand-washing stand C1, or to the toilet tank C40 (a flush toilet tank). A configuration in which the pump 2 is provided in the middle of the hose 8 and connected to the tank 7 or a configuration in which the pump 2 is provided at the tip of the hose 8 and is immersed in the tank 7 is conceivable. Each of these configurations is the installation location of the tank 7 indoors or outdoors, or the distance between the tank 7 and the flush toilet C (for example, the outdoor installation tank 7), the water suction hole of the hand wash basin C1 of the flush toilet C, or the pump 2 is selected in consideration of the capacity of 2. And when it faces the water receiving surface C30, it has the characteristic which can be visually observed, the characteristic which can be effectively used as hand-washing water, etc. When the toilet tank C40 is faced, it can maintain the sense of clean water, and is useful for resolving a sense of incongruity.

  The operation and / or structure of the hand wash basin C1, the pump 2, and the control panel 5 of the flush toilet C provided with the second sensor 1 will be described. For example, when the cock (not shown) of the hand wash stand C1 is operated, running water A is discharged from the hand washing tube C20. When the light from the second sensor 1 is blocked by the running water A, the blocking of the second sensor 1 is performed. A command indicating that the light has been shut off is issued from the command unit of the light receiving element 101, and this command is input to the control panel 5. After the determination process of the control panel 5, the control panel 5 gives a command to the pump 2, the pump 2 is operated, and waste water such as rain water and bath water in the tank 7 (hereinafter referred to as waste water) Water is supplied to the water receiving surface C30 of the hand basin C or the toilet tank C40 via the hose 8. When the predetermined water supply is completed and the water level of the toilet tank C40 is slightly before the predetermined position (the ball tap “first sensor” returns to the stop position), this command is transmitted to the control panel 5 and the electromagnetic valve is activated. Then, the running water is stopped from the hand washing tube C20, and the pump 2 is stopped. Thereafter, the remaining water in the hand-washing tube C20 and / or the remaining water in the hose 8 is supplied to the toilet tank C40, and the toilet tank C40 reaches a predetermined water level. Therefore, approximately half of clean water can be supplemented with waste water, and can save water effectively, or prevent dirt, clogging, slippage, or increase in the number of cleanings, such as hand-washing table C1, toilet tank C40, or toilet bowl C50. There are practical benefits such as being effective in prevention. In addition, it is possible to prevent damage to the second sensor and occurrence of corrosion of metal attached to the inside of the toilet tank C40.

  In addition, when the running water A is stopped and the water level of the toilet tank C40 does not reach the predetermined position, there is a special command unit for continuing water supply provided in the control panel 5, and at this time, the water level is predetermined. It is also equipped with a structure in which the supply of wastewater is continued until it is in position. Accordingly, as described above, the wastewater is supplied and when the water level of the toilet tank C40 is restored (the ball tap returns to the stop position), the pump 2 is stopped and the water supply is stopped. In this example, it is useful when the water supply is stopped, and it is useful for troubles, emergencies (water outages), or other troubles.

  In addition, when the second sensor 1 is shut off by hand or the like, a command is issued from the command unit of the light receiving element 101 of the second sensor 1 by this shut-off, and this command is input to the control panel 5. When the water level of the tank C40 is in a predetermined position, the determination unit provided in the control panel 5 does not issue a command to the pump 2, and the running water A and the waste water are not supplied from the hand washing tube C20. In any case, when the water level of the toilet tank C40 is at a predetermined position, all water supply is not performed, and overflow prevention and safety are ensured, which is beneficial as in the conventional case.

  In addition, when there is no amount of waste water, means for diverting waste water from bath water, washing water, and other storage tanks sequentially or selectively, and means for using these waste waters in combination are also possible. In any case, each wastewater can be used beneficially.

  In addition, in the configuration in which the amount of water flowing from the hand-washing tube C20 is made small by the restriction of the valve, the amount of waste water used can be made large compared to the amount of clean water used. It is effective for. The throttle of the amount of flowing water from the hand-washing tube C20 is configured using the electromagnetic piece 10 and the control unit 11 provided in the hand-washing tube C20 (water faucet control device) (not shown). An example of this will be described based on the enlarged cross-sectional schematic diagram of the faucet control device of FIG. 6. The clean water reaches the hand-washing pipe C20 via the pipe 12. A water stop valve 15 is provided, and these electromagnetic pieces 10 are adjusted by a command to the control unit 11 (the manual operation of the constant flow valve 13 or the adjustment of the water stop valve 15 may be included if necessary) This structure controls the amount of running water.
