For a coach toilet clear water tanks system for cold district, comprise clear water tanks, filler pipe, coolant outlet pipe, heating pipe, normally open solenoid valve and normally closed solenoid valve.
Described filler pipe is positioned at clear water tanks top; Described coolant outlet pipe is positioned at bottom clear water tanks, and is connected by the water inlet of pipeline with coach toilet water pump.
Described heating pipe is arranged on clear water tanks inside, and its water inlet is through the water outlet of the first threeway sending and receiving motivation water return pipeline, and its water outlet is through the water inlet of normally open solenoid valve and the second threeway sending and receiving motivation water return pipeline.
Normally closed solenoid valve is provided with between the first described threeway and the second threeway.
Further, be respectively equipped with temperature sensor and water level detector bottom described clear water tanks, described temperature sensor is electrically connected with normally open solenoid valve, normally closed solenoid valve respectively.
Further, emptying ball valve is provided with bottom described clear water tanks.
Further, the side of described clear water tanks is provided with overflow pipe.
From above technical scheme, the utility model effectively can solve the problem of water consumption of cold district coach toilet, meets consumers' demand, and makes the coach toilet hommization more under low temperature environment.

Detailed description of the invention
The utility model flows through clear water tanks system by the refrigerant fluid in driving engine water return pipeline to heat the water in clear water tanks, is described further the utility model below in conjunction with accompanying drawing:
A kind of coach toilet clear water tanks system for cold district as shown in Figure 1, comprises clear water tanks 1, filler pipe 5, coolant outlet pipe 10, heating pipe, normally open solenoid valve 2, normally closed solenoid valve 3, first threeway 13 and the second threeway 9.Described filler pipe 5 is positioned at clear water tanks top, can effectively prevent the water of clear water tanks 1 to be back to filler pipe 5, thus avoids cannot adding water because having water freezing in filler pipe 5.Described coolant outlet pipe 10 is positioned at bottom clear water tanks, and is connected by the water inlet of pipeline with coach toilet water pump 15.Described heating pipe is arranged on clear water tanks inside, and heating pipe water inlet and water outlet are all arranged on the top of clear water tanks.
Specifically, the water outlet of driving engine water return pipeline 14 connects the water inlet end of the first threeway 13 by pipeline, and two water sides of the first threeway 13 connect the water inlet end of heating pipe water inlet 4 and normally closed solenoid valve 3 respectively by pipeline.The water side of normally closed solenoid valve 3 connects the first water inlet end of the second threeway 9 by pipeline.Heating pipe water outlet 7 connects the second water inlet end of normally open solenoid valve 2 by pipeline, and the water inlet end of pipeline connecting engine water return pipeline 14 is passed through in the water side of the second threeway 9.In clear water tanks system described in the utility model, coolant outlet pipe, the first threeway, the second threeway, driving engine water return pipeline and connect the pipeline of all parts, outside is all enclosed with heat-insulation layer, can temperature retention time be extended like this, prevent electromagnetic valve frequent operation simultaneously, extend electromagnetic valve service life.
Further, be respectively equipped with temperature sensor 11 and water level detector 12 bottom described clear water tanks, described temperature sensor 11 is electrically connected with normally open solenoid valve 2, normally closed solenoid valve 3 respectively.Temperature sensor, for detecting the temperature of the water in clear water tanks in real time.Water level detector, for detecting the water position status in clear water tanks.
Further, emptying ball valve is provided with bottom described clear water tanks 1.Described emptying ball valve, for by emptying for the water of water tank, prevents rear water freezing overnight.
Further, the side of described clear water tanks 1 is provided with overflow pipe.
Above-mentioned in the coach toilet clear water tanks system of cold district, the refrigerant fluid in driving engine water return pipeline 14 can flow through two paths and one closed circuit.Article 1, path is: first, and refrigerant fluid, from the water outlet of driving engine water return pipeline 14, arrives heating pipe water inlet 4 through the first threeway 13; Secondly, after flowing through the heating pipe being positioned at clear water tanks, flow out from heating pipe water outlet 7; Finally, arrive the water inlet of driving engine water return pipeline 14 through normally open solenoid valve 2 to the second threeway 9 from heating pipe water outlet 7, enter next driving engine backwater circulation.Now, normally open solenoid valve 2 is opened, and normally closed solenoid valve 3 is closed, and the refrigerant fluid in driving engine water return pipeline 14 heats the water in clear water tanks.Article 2 path is: first, and refrigerant fluid, from the water outlet of driving engine water return pipeline 14, arrives normally closed solenoid valve 3 through the first threeway 13; Secondly, refrigerant fluid arrives the second threeway 9 from normally closed solenoid valve 3 again; Finally, flow back into driving engine water return pipeline 14 from the second threeway 9.Now, normally open solenoid valve 2 cuts out, and normally closed solenoid valve 3 is opened, and the refrigerant fluid in driving engine water return pipeline 14 stops heating the water in clear water tanks.Closed circuitly be: first, refrigerant fluid arrives heating pipe water inlet 4 from the water outlet of driving engine water return pipeline 14 through the first threeway 13; Secondly, refrigerant fluid arrives heating pipe water outlet 7 from heating pipe water inlet 4 again; Finally, refrigerant fluid flow to normally open solenoid valve 2 stopping flowing from heating pipe water outlet 7.Now, normally open solenoid valve 2 cuts out, and normally closed solenoid valve 3 is opened, and the refrigerant fluid be retained in heating pipe plays insulation effect, for keeping the water temperature in clear water tanks.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
