Detailed description of the invention
The present invention flows through clear water tanks system by the refrigerant fluid in driving engine water return pipeline to heat the water in clear water tanks, and below in conjunction with accompanying drawing, the present invention will be further described:
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 of the present invention, 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 extend temperature retention time like this, prevents electromagnetic valve frequent operation simultaneously, extends 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.
The present invention also comprises a kind of control method of the coach toilet clear water tanks system for cold district, and as shown in Figure 2, the method comprises the following steps:
The water temperature threshold value T0 of S1, setting clear water tanks, passenger vehicle starts.
S2, normally open solenoid valve are opened, and normally closed solenoid valve is closed, and the refrigerant fluid in driving engine water return pipeline heats the water in clear water tanks.
S3, by being arranged on the water temperature T of the temperature sensor Real-time Collection clear water tanks bottom clear water tanks.
The size of the water temperature threshold value T0 of S4, the water temperature T comparing the clear water tanks of Real-time Collection and clear water tanks, if T < is T0, normally open solenoid valve is opened, and normally closed solenoid valve is closed, and the refrigerant fluid in driving engine water return pipeline continues to heat the water in clear water tanks.If T >=T0, temperature sensor sends energizing signal respectively to normally open solenoid valve and normally closed solenoid valve, and normally open solenoid valve cuts out, and normally closed solenoid valve is opened, and the refrigerant fluid in driving engine water return pipeline stops heating the water in clear water tanks.
S5, return perform step S3.
By the control method of above-mentioned a kind of coach toilet clear water tanks system for cold district, can ensure that the water in coach toilet clear water tanks maintains in the scope of a setting, improve the performance of clear water tanks system.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
