The specific embodiment

Below in conjunction with the drawings and specific embodiments water-saving closet of the present utility model is further described.

As shown in Figures 1 to 4, the utility model water-saving closet, by the toilet 1 that has water inlet and be arranged on toilet afterbody top have water inlet 21, delivery port 22 cisterns 2 are formed, the delivery port 22 of wherein said cistern is connected by the inlet port of pipeline with toilet 1, comprises that also a secondary water return water tank 3 that has water inlet 31 and a delivery port 32, water pump 4 and one are used for the level control switch for water 51 of control of pump open and close; Wherein, the water inlet 21 of the delivery port 32 of described secondary water return water tank 3 and cistern 2 is connected by pipeline; Described water pump 4 is installed on the pipeline between the water inlet 21 of the delivery port 31 of described secondary water return water tank 3 and cistern 2; Described level control switch for water 51 is installed in the upper limit water level place in the cistern 2.

The water inlet 31 of above-mentioned secondary water return water tank 3 can be used for connecting the sewer pipe in people's daily life, in order to prevent that dirt from falling in the secondary water return water tank, can filter be set at the inlet port place, it is big that the volume of secondary water return water tank 3 should be tried one's best, so that hold more secondary water; Because the water in the secondary water return water tank is transported in the cistern after pressurizeing by water pump 4, so in the actual installation process, the position of secondary water return water tank can be lower, so also is convenient to reclaim the daily life water;

The purpose of above-mentioned level control switch for water 51 is that the water in cistern 2 is when reaching upper limit water level, to switch off the pump, stop into water, therefore its structure can be selected various switches according to actual conditions, as selecting travel switch, also can selecting magnetic induction switch etc., and, select different mounting meanss according to the difference of switch kind.

Its course of work is such, when people need wash by water, open the bath switch on the cistern 2, by the outlet valve in its drive cistern, water in the cistern 2 is flowed out from the delivery port 22 of cistern, at this moment, level control switch for water 51 is closed, and water pump 4 is started working, and 3 secondary water flows out from its delivery port 32 in the secondary water return water tank, arrive cistern by water pump 4 pressurization backs, because the speed of the cistern water outlet speed of water inlet is wanted fast (diameter of the water inlet pipe of cistern will be far smaller than the diameter of delivery port usually), therefore, before outlet valve closes, secondary water all can flow out by the delivery port of cistern, till only closing to the interior outlet valve of flushing tank, when water level did not reach upper limit water level, level control switch for water was in closure state all the time, supply water by water pump 4, advance when water level reaches upper limit water level, level control switch for water is opened, and makes Pump Failure, stopped water supply, in order to use next time.

In order to prevent in water supply process in cistern, water in the secondary water return water tank 3 is not enough, make water pump in running order always, further improve, also comprise second level control switch for water 52 that is used for the control of pump open and close as the utility model ground; Wherein, described second level control switch for water 52 is installed in the lower limit water level place in the secondary water return water tank 3.Like this, when not having water in the secondary water return water tank 3, second level control switch for water 52 can be opened, and makes Pump Failure, to avoid the damage of water pump.

In order to prevent the generation of above-mentioned situation, improve further as the utility model, as shown in Figure 3, on described toilet, also be provided with second cistern 6, the delivery port of described second cistern is connected with the inlet port of toilet by pipeline, and the water inlet of described second cistern is connected with water supply pipe.Like this, when the secondary water in it is found that cistern can not be satisfied the demand, can also use the tap water washing closestool.The cistern and second cistern that Fig. 3 plants are placed side by side, as a kind of distortion of the present utility model, and also can the cistern and second cistern is stacked up and down.

As a same reason, improve further, above the side of described secondary water return water tank, be provided with overfall gap as the utility model.Like this, can be at secondary water more and when surpassing the volume of secondary water return water tank, unnecessary secondary water is flow in original sewer pipe by overfall gap.
