Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet structure in which rainwater falling on a roof can be used for flushing a flush toilet. 2. Description of the Related Art Japan is one of the most rainy countries in the world, and the annual rainfall is about 1750 mm / year, the terrain is steep, residential land and roads are paved, and so on. Often, water immediately flows out into the sea through rivers, and attempts have been made to adopt a structure that stores rainwater in houses so that rainwater can be used effectively. Thus, the stored water was used for watering and irrigation. [0003] If a rainwater storage tank is provided so as to store rainwater as described above and used not only for water sprinkling but also for flushing a flush toilet, it is possible to save a water service charge. If only rainwater is used, the rainwater storage tank will be emptied immediately after a rainless day, and the water supply must be used. Therefore, a toilet that can be properly used from two water sources according to the amount of water storage has been desired. In addition, when water and rainwater are selectively supplied to one low tank, a switching valve is required, and it is necessary to switch the switching valve before supplying water. In addition, when a mixing tap is used, when both are opened and the water supply side becomes a negative pressure, there is a possibility that rainwater may leak into the water supply. Therefore, the present invention provides two low tanks,
The two water sources will be connected to separate low tanks so that they can be used according to the amount of rainwater stored. [0004] The present invention uses the following means to solve the above problems. The gutter provided the eaves of the roof and connected to the rainwater cistern, pooled rainwater on the roof to the rainwater cistern, in the structure that is connected to a low tank of flush toilets through a pipe from 該雨water storage tank, the low tank the in pair disposed, one to supply water from the rain water storage tank as rainwater low tank, while the supply of water from the water supply as water supply low tank, the rain
The diameter of the pipe from the water storage tank is larger than the diameter of the water supply pipe.
As a large diameter, it extends from the rainwater storage tank to the rainwater low tank.
The water supply time is shortened, and the rainwater low tank drain lever is
Make it larger than the drain lever of the water low tank,
-The tank is for normal use and the low-water tank is for emergency use.
Are configured to be visually recognizable . Embodiments of the present invention will be described with reference to the accompanying drawings. 1 is a schematic side view of a rainwater use system in which a two-row tank toilet of the present invention is arranged in a house, FIG. 2 is a perspective view of a rainwater use two-row tank toilet, FIG. 3 is a side view thereof, and FIG. FIG. 5 and FIG. 5 are front sectional views of a drain hose part, and FIG. 6 is a perspective view showing another embodiment of a two-row tank. A house provided with a 2-row tank toilet of the present invention will be described with reference to FIG. The house shown in FIG. 1 is a two-storey building. An eaves gutter 1 is arranged in a substantially horizontal direction at the eaves below the roof R. Rainwater is introduced into the vertical rainwater storage tank 4 through the vertical gutter 3 that is provided upright. The rainwater storage tank 4 is erected on the side of the wall of the house so that a predetermined capacity can be stored. A filter is provided at an intake from the downspout 3 of the rainwater storage tank 4 to prevent dust from entering, and outlets 4a, 4b, and 4c are provided in the middle and lower part, and a pipe is provided at the outlet 4a. 1
0 to the flush toilet 12 on the second floor to supply water, and the outlet 4b is connected to the flush toilet 13 on the first floor via the pipe 11 to supply water. Can be used for washing.
The outlet 4c is provided with a faucet 14 so that the faucet 14 can be used for watering a garden, watering a vegetable garden, washing a car, and the like. When the water level in the rainwater storage tank 4 is higher than the position where the water is discharged, the water can be discharged without using a pump or the like by the potential energy, and the water supply can be performed at a low cost without requiring a driving source. I can do it. However, the position and the number of the outlets 4a, 4b, 4c are not limited. Further, pipes 5 and 6 are connected to the lower end of the rainwater storage tank 4, the other ends of the pipes 5 and 6 communicate with the underground tank 9, and the upper end of the pipe 5 is connected to the rainwater storage tank 4. Extending to the upper part, surplus water (overflow) in the rainwater storage tank 4 is stored in the underground tank 9, and a pump 7 is interposed in the middle of the pipe 6 to pump up the water in the underground tank 9. When the amount of water in the rainwater storage tank 4 decreases, replenishment is possible. An overflow pipe 14 is connected to the upper part of the underground tank 9, and the other end of the overflow pipe 14 is discharged to a drain or the like via a permeation mass 15. It is infiltrated into groundwater to prevent rainwater from flowing quickly into the river. In addition, the flush toilets 12 and 13 have drainage pipes 16.
7 and connected to a septic tank 19 (or sewer). In this way, the rainwater that has fallen on the roof R is collected by the eaves gutter 1 and is introduced into the rainwater storage tank 4 via the call gutter 2 and the vertical gutter 3. When full, water is stored in the underground tank 9. Further, when the underground tank 9 becomes full, the overflow pipe 1
4, the water is penetrated into the ground through the permeation mass 15 so that water can be retained under the ground. Next, a flush toilet 13 having a two-row tank toilet according to the present invention will be described. That is, FIGS.
As shown in (1), a toilet 21 is installed in a toilet 20, and a low tank 22 is arranged at the rear of the toilet 21. The low tank 22 includes a clean water low tank 22L and a rainwater low tank 22R.
And are arranged side by side. The clean water low tank 2
The 2L and the low rainwater tank 22R are arranged symmetrically with the same configuration. However, as shown in FIG. 6, the low tank 22 may have a partition wall 22b formed in the center of the tank to integrally form the low water tank 22L 'and the low water tank 22R'. In this case, water is supplied from both sides of the raw tank 22 ', and the piping configuration and the internal water supply / drainage structure are configured in the same manner as the raw tank provided with two independently.
The material of the raw tank 22 can be made of pottery, metal, synthetic resin, or the like, and is not limited. Water supply pipes 24L and 24 are provided on the inner (or outer) side surfaces of the low water tank 22L and the low water tank 22R.
R is communicated, and a water pipe 26 and a pipe 11 from the rainwater storage tank 4 protrude upward from a floor 27 on both sides of a rear portion of the toilet 21 and stop between the water pipe 26 and the water supply pipe 24L. A water faucet 25L is interposed, and the pipe 11 and the water supply pipe 2 are provided.
4R, a water stopcock 25R is interposed, and the low tank 2
At the time of maintenance of the inside of 2 etc., a water stopcock is closed so that water supply can be stopped. In addition, the water pipe 26 and the pipe 11 can be configured so as to protrude from the left and right wall surfaces or the rear wall surface, and in this case, the same pipe configuration as described above is used. Further, the pipe 1 from the rainwater storage tank 4
1 and the diameter of the water supply pipe 24R are equal to the water supply water pipe 26 and the water supply pipe 2.
The diameter is larger than the diameter of 4L. In other words, the tap water is usually pumped, so that the pipe diameter may be small. However, since the rain water uses only the potential energy, it takes time to fill the rain water low tank 22R with the same diameter pipe. Therefore, the diameter of the pipe from the rainwater storage tank 4 to the rainwater low tank 22R is increased to shorten the time for supplying water to the rainwater low tank 22R. Further, a viewing window 22a (FIG. 2) is provided on the front of the rainwater low tank 22R so that it is easily understood whether or not water is accumulated in the rainwater low tank 22R. However, a water level gauge linked to a floating ball 30b to be described later can be arranged. Since the inside of the low tank 22 has the same structure on the left and right, the structure of the clean water low tank 22L on one side will be described. The end of the water supply pipe 24 is inserted into the clean water low tank 22L and connects the ball tap 30. The ball tap 30 includes a valve 30a and a floating ball 30b that opens and closes the valve. The floating ball 30 has a base arm pivotally supported by the valve 30a, and a middle part of the arm is connected to a spool of the valve. When the ball 30 goes down, the valve opens, and when it goes up, the valve closes. An upper end of a drainage hose 23 communicates with the inner and lower surfaces of the clean water tank 22L.
A rubber float 31 is disposed at the upper end of the drain hose 23 in the L so as to cover the opening, and the upper portion of the rubber float 31 is connected to a drain lever 34 via a chain 32 and a lever rod 33. Is disposed in front of the low tank 22 so that the rubber float 31 can be lifted by rotating the drainage lever 34. However, the drainage lever 34R for rainwater is normal or slightly larger, and the drainage lever 34L for water supply has a small shape so that it can be visually recognized that the drainage lever 34R for rainwater is normally used.
The drainage lever 34L for tap water is designed to be recognized as emergency. An overflow pipe 35 communicates with an upper part of the drain hose 23 and stands upright. As shown in FIG. 5, the drain hose 23 is formed in a Y-shape, and has a bifurcated upper end communicating with the lower portions of the low water tank 22L and the low water tank 22R, and a pipe extending from the upper end to the middle part. The portions 23a and 23b are formed in an S-shape, and the lower ends thereof communicate with the rear portion of the toilet 21. The pipe section 23
The reason why the a · 23b is curved in an S-shape is that it smoothly flows vertically downward when merging in the middle part, for example, when water flows in the A direction from the pipe part 23a. Then, the rubber float 31 in the rainwater low tank 22R is lifted by the water pressure by flowing to the pipe portion 23b side at the branch part in the middle part so that the rainwater does not flow. Similarly, if the rainwater is B
When flowing in the direction, the rubber float 31 in the clean water low tank 22L is lifted to prevent the clean water from flowing, thereby preventing malfunction. With this configuration, when rainwater is stored in the vertical rainwater storage tank 4, the potential energy of the water in the rainwater storage tank 4 causes the rainwater to flow into the rainwater low tank 22R lower than the water level. 11, Stopcock 25R
(Open), water is supplied via the water supply pipe 24R and the ball tap 30. When this water accumulates in the rainwater low tank 22R, the water level rises, and the floating ball 30b rises, the arm on which the floating ball 30b is mounted is turned, the valve 30a is closed and the water supply is stopped, and the set amount of water is stopped. Water accumulates in the rainwater low tank 22R. Then, similarly, the water in the low-water low tank 22L is supplied from the water supply, and a set amount of water is stored. When there is water in the rainwater low tank 22R, when the drainage lever 34R is rotated after using the toilet, the rubber float 3 is moved through the lever rod 33 and the chain 32.
1 is lifted, the upper end opening of the drainage hose 23 is opened, and the water in the rainwater low tank 22 </ b> R is discharged to flow from the drainage hose 23 into the toilet 21. Also, the rainwater low tank 22
When there is no water in R, the drainage lever 34L on the low-water low tank 22L side is rotated to drain the water as described above. As described above, the present invention has the following advantages. In other words, since two low tanks for water supply and rainwater are provided in the toilet, if rainwater is stored in the rainwater storage tank, the rainwater can flow to the flush toilet, and the rainwater is stored in the rainwater storage tank. When there is no water, it can be flushed with water from the water supply, and can be easily used depending on the amount of water in the rainwater storage tank.
And the water resource called rainwater can be used effectively, and the consumption of the water supply can be saved. For rainwater
The drainage lever 34R is normally or slightly larger, and is used for water supply.
The water lever 34L has a small shape,
