Description
Technical field
The utility model relates to a kind of electrothermic warm water device system, especially a kind ofly realizes on train water heater self-control water level height, water inlet speed, and to its heating, and the controlled water heater system of temperature.
Background technology
In prior art, train water heater generally adopts liquid level relay, can only realize the height that water heater oneself controls liquid level, and water inlet speed is uncontrollable, and function ratio is limited to; Affected the demand of passenger to water on car.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of electrothermic warm water device system is provided, and can realize water heater self-control water level height on train, water inlet speed, and to its heating.
The technical scheme providing according to the utility model, a kind of electrothermic warm water device system, comprise control cabinet and heating cabinet, in control cabinet, be provided with control circuit, power lamp HL1 and heating signal lamp HL2, on heating cabinet, be provided with water inlet pipe and outlet pipe, it is characterized in that: in described heating cabinet, be provided with by three groups of heating DR1-DR3 the main circuit that is unified into, after three groups of heating DR1-DR3 are connected in parallel, be connected respectively with contactor KM, heating DR1-DR3 is connected with leakage switch Q1 by contactor KM; Described control circuit comprises circuit breaker Q 2, lack of water controller WG, contactor KM and temperature controller ATC, after the coil of contactor KM is in parallel with diode VD, ATC connects with temperature controller, more in parallel with lack of water controller WG, and lack of water controller WG two ends are connected with leakage switch Q1 with circuit breaker Q 2 respectively; Described lack of water controller WG comprises 8 binding posts, the 3rd binding post that be respectively the first binding post of being connected with leakage switch Q1 with circuit breaker Q 2 and the second binding post, is connected with water-level probe S11, S12 and the 4th binding post, the 5th binding post and the 6th binding post, the 7th binding post being connected with normally opened contact WT1, WT2 and the 8th binding post that are connected with flow switch G1, G2.
Described temperature controller ATC connects with meltable normally-closed contact ER, and the coil of contactor KM is connected with normally opened contact WT1, the WT2 of lack of water controller.
Described heating signal lamp HL2 connects with the normally opened contact of contactor KM.
Described heating DR1-DR3 adopts electrothermal tube.
The utlity model has following advantage: (1) temperature is controlled: original train water heater is owing to not adopting lack of water controller, and the hot water of outflow is overheated or excessively cold, and people will not feel well when washing one's hands; Adopt this mechanism, can guarantee the water outlet transition of constant temperature, more humane.(2) water intake velocity is adjustable: original train water heater does not have flow control switch, if when train passenger is too much, there will be short water supply, water while being not easy to passenger's urgency.(3) stable working state: according to water situation on car, intellectuality increases or reduce the constant temperature that flow carrys out the water level of subsidiary water tank and keeps water; Avoid due to short water supply what time moisturizing and fault that electrical equipment overload occurs, increased the service life of water heater.
Accompanying drawing explanation
Fig. 1 is the electrical schematic diagram of electrothermic warm water device system main circuit described in the utility model.
Fig. 2 is the electrical schematic diagram of electrothermic warm water device system, control circuit described in the utility model.
Fig. 3 is the schematic diagram of described lack of water controller.
The specific embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, electrothermic warm water device system described in the utility model comprises control cabinet and heating cabinet, in control cabinet, be provided with control circuit, power lamp HL1 and heating signal lamp HL2, on heating cabinet, be provided with water inlet pipe and outlet pipe, in heating cabinet, be provided with by three groups of heating DR1-DR3 the main circuit that is unified into, after three groups of heating DR1-DR3 are connected in parallel, be connected respectively with contactor KM, heating DR1-DR3 is connected with leakage switch Q1 by contactor KM; Described control circuit is connected with heating DR1-DR3 by contactor KM, and is connected with Inlet and outlet water switch by lack of water controller WG; Described control circuit comprises circuit breaker Q 2, lack of water controller WG, contactor KM and temperature controller ATC, contactor KM is in parallel with diode VD, after connecting with temperature controller ATC again, more in parallel with lack of water controller WG, lack of water controller WG two ends are connected with leakage switch Q1 with circuit breaker Q 2 respectively; Described temperature controller ATC connects with meltable normally-closed contact ER, and contactor KM connects with normally opened contact WT1, the WT2 of lack of water controller; As shown in Figure 3, described lack of water controller WG comprises 8 binding posts, the 3rd binding post 3 that be respectively the first binding post 1 of being connected with leakage switch Q1 with circuit breaker Q 2 and the second binding post 2, is connected with water-level probe S11, S12 and the 4th binding post 4, the 5th binding post 5 and the 6th binding post 6, the 7th binding post 7 being connected with normally opened contact WT1, WT2 and the 8th binding post 8 that are connected with flow switch G1, G2;
