Water-saving toilet pan
Technical field
The utility model relates to a kind of water-saving toilet pan, belongs to technical field of sanitary ware.
Background technology
Present employed water-saving toilet pan generally all is directly to use tap water to wash by water, running water pipe directly is communicated with to go into water tank, switch by float switch control tap water, wash by water by people's operational size water yield switch, utilize the big or small water yield to select to reach the purpose of water saving, but still all will use a large amount of tap water every day like this, water resource waste is serious.And all be direct discharging the daily life sewage in our daily life (as face washing water, the water etc. of washing one's hands), be not fully utilized.As seen employed water-saving toilet pan can not effectively utilize daily life sewage in the life at present, can not effectively save tap water.
The utility model content
The purpose of this utility model just is to provide a kind of can effectively utilize daily life sewage, effectively save the water-saving toilet pan of tap water.
For achieving the above object, solution of the present utility model is: the daily life sewage pipe is communicated with toilet seat water tank, running water pipe has two-way to be communicated with into water closet, wherein one road running water pipe is communicated with into water tank by float valve, another road running water pipe is communicated with into water tank by normally closed solenoid valve, be provided with liquid-level switch in the inboard high position of water tank, below the water closet cushion, be provided with automatic reset switch, the coil of electromagnetic valve, liquid-level switch, automatic reset switch inserts power supply by the lead series connection, liquid-level switch is a closed type, automatic reset switch is an open type, and a water tank high position also is provided with bleed off pipe, and bleed off pipe is communicated with sewer pipe.
Such structure makes daily life sewage can flow into toilet seat water tank, thereby can effectively utilize daily life sewage to save tap water effectively, even under the situation that does not have enough daily life sewages to replenish, also can utilize the tap water flushing closestool.
Description of drawings
Fig. 1 is the structure principle chart of the utility model water-saving toilet pan.
Fig. 2 is the circuit theory diagrams of the utility model water-saving toilet pan.
Among the figure: 1-closet body, 2-running water pipe, 3-electromagnetic valve, 4-running water pipe, 5-waste water pipe, 6-water tank, 7-float valve, 8-liquid-level switch, 9-size water yield selector switch, 10-bleed off pipe, 11-cushion ring, 12-automatic reset switch.
The specific embodiment
Fig. 1 to Fig. 2 has provided the specific embodiment of the utility model water-saving toilet pan, it comprises closet body 1, water tank 6, running water pipe 4, float valve 7, big or small water yield selector switch 9, these belong to prior art, in addition, the utility model water-saving toilet pan also comprises waste water pipe 5, running water pipe 2, normally closed solenoid valve 3, liquid-level switch 8, automatic reset switch 12, bleed off pipe 10.Waste water pipe 5 is communicated with the water tank 6 of water closet, running water pipe is divided into two-way and is communicated with into water closet, wherein one the tunnel is that running water pipe 4 is communicated with to go into water tank 6 by float valve 7, another road is that running water pipe 2 is communicated with to go into water tank 6 by electromagnetic valve 3, be provided with liquid-level switch 8 in water tank 6 inboard high positions, below water closet cushion ring 11, be provided with automatic reset switch 12, the coil of electromagnetic valve 3, liquid-level switch 8, automatic reset switch 12 inserts power supply by the lead series connection, power supply can be battery or electric main, liquid-level switch 8 be closed type be liquid level when not reaching the position at its place liquid-level switch 8 be closed, automatic reset switch 12 is that open type is that not put down when pushing down it automatic reset switch 12 be to disconnect to cushion ring 11, the mouth of pipe of bleed off pipe 10 is positioned at the high position of water tank 6, and bleed off pipe 10 is communicated with sewer pipe.
During use, float valve 7 should be adjusted to the low water stage closed condition, and this low water stage is a standard to be fit to people's water supply volume of going to the lavatory, and liquid-level switch 8 is installed in high water level, and this high water level should be greater than people's water supply volume of having a bowel movement.It in the initial state water tank 6 the low water stage tap water, this moment, float valve 7 was closed, and tap water can not enter water tank 6 through running water pipe 4, and this moment is if there is daily life sewage, then waste water enters water tank 6 by waste water pipe 5, is full of the unnecessary waste water in water tank 6 backs and overflows through bleed off pipe 10 places; When if no daily life sewage needs to have a bowel movement again, put down cushion ring 11, automatic reset switch 12 closures, the water in the water tank 6 is not if reach high water level, and liquid-level switch 8 is closed so, this moment, circuit was connected, the coil of electromagnetic valve 3 gets the electronic opens solenoid valve 3 of doing, and tap water enters water tank 6 through running water pipe 2 by electromagnetic valve 3, when water is filled to high-order liquid-level switch 8, liquid-level switch 8 disconnects, and closes electromagnetic valve 3 cut-out running water pipes 2 thereby the coil losing electricity of electromagnetic valve 3 resets.When not using water closet usually, thereby the position that cushion ring 11 is positioned at open does not make automatic reset switch 12 be positioned at normally open so that it does not push down automatic reset switch 12, like this, the utility model water-saving toilet pan is under the situation of guaranteeing the low water stage water yield, can admit daily life sewage to greatest extent, even do not having under the situation of daily life sewage simultaneously, also can in time replenish the needs that tap water satisfies the big yield water, and still kept adopting big or small water yield switch 9 to select the water saving mode of the bath water yields, thereby so the utility model water-saving toilet pan can effectively utilize daily life sewage to save tap water effectively.
The position of the low water stage closed condition of float valve 7 is adjustable, and the high and low position of liquid-level switch 8 also is adjustable, to be fit to the water supply volume requirement of different people.
