Abstract

The utility model relates to a rainwater collecting and draining system, in particular to a rainwater collecting system for the flushing toilet of a building. The utility model comprises a drainage trench arranged on the roof of the building and a rainwater pipe which is vertically arranged on the wall of the building. A rainwater collecting box is arranged close to the drainage trench and is communicated with the drainage trench. The water collecting box is also communicated with the rainwater pipe. A first electromagnetic valve is arranged on the upper end of the rainwater pipe. The rainwater collecting box is provided with a water outlet pipe which is communicated with the water tank of a toilet inside the building. A second electromagnetic valve is connected the upper end of the water outlet pipe. A control unit is connected with the first electromagnetic valve, the second electromagnetic valve and a water level detector arranged in the rainwater collecting box. The technical problem that the current drainage system arranged on the building roof has the functions of rainwater collecting and draining and the rainwater is not sufficiently utilized is solved by the utility model which ensures the domestic water cost to be reduced for the users and inhabitants.

Description

A kind of rainwater of building is collected flushing unit
Technical field
The utility model relates to the rainwater of rainwater collection and exhaust system, particularly a kind of building and collects flushing unit.
Background technology
As everyone knows, tellurian freshwater resources are quite limited, and because the geographical position difference and the weather difference of each countries and regions have caused the rainfall distributed pole inhomogeneous.Therefore, saving limited water resource is that people need the work paid attention to.The work of water saving comprises that also some are not added the freshwater resources that make full use of further utilizes except will forming good personal habits.
In addition, all building roofs all have drainage system, and this drainage system comprises the gutter that is arranged on the roof, and the effect in gutter mainly is exactly to collect the rainwater that drops on the roof.This gutter is communicated with rainwater down pipe, and rainwater down pipe generally all is vertically to be connected on the skin.During use, when the rainwater in roof and balcony gutter flows down through rainwater down pipe, all be past dirty, so just can effectively avoid the roof of building to produce destruction owing to gathering rainwater along the inwall of rainwater down pipe.
But the drainage system of existing building does not have to make full use of the collecting function of rainwater, and rainwater is further utilized, and is very unfortunate.
The utility model content
The purpose of this utility model is to provide a kind of rainwater of building to collect flushing unit, the drainage system that mainly solves existing building roof just has rainwater and collects and discharge function, the technical problem that rainwater is made full use of can not make resident family and user reduce the cost of living water use greatly.
For addressing the above problem, the utility model is achieved in that
A kind of rainwater of building is collected flushing unit, it comprises the gutter that is arranged on the building roof and vertically is arranged on rainwater down pipe on the building wall, it is characterized in that: have the rainwater collecting box near this gutter, this rainwater collecting box is communicated with the gutter, the rainwater collecting box also is communicated with rainwater down pipe, and this rainwater down pipe upper end has first electromagnetic valve; This rainwater collecting box also has an outlet pipe that is communicated with toilet cistern in the building, and this outlet pipe upper end is connected with second electromagnetic valve; One control module connects above-mentioned first electromagnetic valve, second electromagnetic valve and is arranged at the interior level sensor of rainwater collecting box.
The rainwater of described building is collected flushing unit, it is characterized in that: have a screen pack in this rainwater collecting box.
By technique scheme, the beneficial effects of the utility model are:
Rainwater collecting box of the present utility model can make full use of the rainwater of collecting on the building roof, especially for flushing the toilet, so just can utilize water resource fully, and can reduce the water cost of resident family.

The specific embodiment
See also Fig. 1,2, they are structural representations of the rainwater collection flushing unit of a kind of building of the utility model.As shown in the figure: it comprises and is arranged at the gutter 11 on building 1 roof and vertically is arranged on rainwater down pipe 12 on building 1 wall.Have rainwater collecting box 2 near this gutter 11, this rainwater collecting box 2 is communicated with gutter 11, and rainwater collecting box 2 also is communicated with rainwater down pipe 12, and these rainwater down pipe 12 upper ends have first electromagnetic valve 31; This rainwater collecting box 2 also has an outlet pipe 5 that is communicated with toilet cistern 4 in the building 1, and these outlet pipe 5 upper ends are connected with second electromagnetic valve 32; One control module 3 connects above-mentioned first electromagnetic valve 31, second electromagnetic valves 32 and is arranged at level sensor 33 in the rainwater collecting box 2.
During use, the rainwater of collecting in the roof valley 11 can enter rainwater collecting box 2, and at this moment first electromagnetic valve 31 is in closure state.When unnecessary rainwater (promptly pass through level sensor 33 when control module 3 sends signals, but first electromagnetic valve, 31 time openings is discharged in the full back of the collection of the rainwater in the rainwater collecting box 2.Second electromagnetic valve 32 then is arranged at the state of often opening, so that water filling in toilet cistern 4, so just can use the rainwater after the collection to flush the toilet fully.
In addition, have a screen pack 21 in this rainwater collecting box 2, can the rainwater after collecting be filtered like this, avoid each pipeline is resulted in blockage.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
