The device comprises a water inlet pipeline, a water outlet pipeline, a draining pipeline and a main-control substrate, wherein a draining port is arranged on the draining pipeline, a water outlet end electromagnetic two-way valve is arranged at a position of the intersection of the draining pipeline and the water outlet pipeline, a water inlet end electromagnetic two-way valve is arranged at a position of the intersection of the draining pipeline and the water inlet pipeline, at least one of the water inlet pipeline, the water outlet pipeline and the draining pipeline is provided with a temperature sensor, and the water outlet end electromagnetic two-way valve, the water inlet end electromagnetic two-way valve and the temperature sensor are respectively connected with the main-control substrate electrically. The device has the advantages of being capable of automatically draining, effectively preventing the gas water heater from being frozen due to low temperature in winter and saving the electrical energy.
Description
Technical field
The utility model relates to a kind of gas heater defroster, specifically relates to a kind of gas heater and uses the automatic drainage device.
Background technology
At present, owing to receive the influence of environment, the various places climate change is bigger, causes some areas temperature very low.Therefore; It is imperative to solve the antifreeze problem of gas heater; The gas heater that sell the market is divided into anti-freeze type gas heater and non-anti-freeze type gas heater, and the anti-freeze type gas heater has automatic heating device, makes ducted water be unlikely to freeze through the electrical heating effect; But when temperature is extremely low, still need manually to sluice, and waste electric energy; Though but not the anti-freeze type gas heater can be avoided bursting by freezing fully; But the user operates inconvenience, needs the user manually to sluice, promptly manual dismantle drain valve and screen modules draining; Operation inconvenience; And in case run into that user carelessness is forgotten or bursting problem such as temperature decline suddenly, will cause the pipeline bursting by freezing of gas heater water tank and leak, cause unnecessary loss to the user.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model proposes a kind of gas heater and uses the automatic drainage device, but has automatic drainage, effectively avoids crossing because of winter temperature the advantage of low and freezing gas heater.
The technical scheme of the utility model is achieved in that
A kind of gas heater is used the automatic drainage device; Comprise inlet pipeline, outlet pipeline, drain water circuit and master control substrate; Said drain water circuit is provided with discharge opening; The infall of said drain water circuit and said outlet pipeline is provided with the water side magnetic valve; The infall of said drain water circuit and said inlet pipeline is provided with the water inlet end magnetic valve, and at least one place is provided with temperature sensor on said inlet pipeline, outlet pipeline and the drain water circuit, and said water side magnetic valve, said water inlet end magnetic valve and said temperature sensor electrically connect with said master control substrate respectively.
As the further improvement of the utility model, said water side magnetic valve and water inlet end magnetic valve are respectively the electromagnetism two-way valve.
The beneficial effect of the utility model is: through on inlet pipeline, outlet pipeline and drain water circuit, temperature sensor being set; The temperature of water in each water pipeline of detecting real-time gas heater; When the detecting temperature reaches design temperature; Start and the completion automatic drainage, can avoid fully owing to temperature is crossed the low problem that causes gas heater to damage, and not waste electric energy.
Description of drawings
Fig. 1 is the utility model structural representation;
In conjunction with accompanying drawing, explanation below doing:
1---water side magnetic valve 4---discharge opening
2---water inlet end magnetic valve 5---master control substrate
3---temperature sensor
The specific embodiment
As shown in Figure 1; A kind of gas heater is used the automatic drainage device; Comprise inlet pipeline, outlet pipeline, drain water circuit and master control substrate 5; Said drain water circuit is provided with discharge opening 4, and the infall of said drain water circuit and said outlet pipeline is provided with water side magnetic valve 1, and the infall of said drain water circuit and said inlet pipeline is provided with water inlet end magnetic valve 2; At least one place is provided with temperature sensor 3 on said inlet pipeline, outlet pipeline and the drain water circuit, and said water side magnetic valve 1, said water inlet end magnetic valve 2 and said temperature sensor 3 electrically connect with said master control substrate 5 respectively.
Preferably, said water side magnetic valve 1 and water inlet end magnetic valve 2 are respectively the electromagnetism two-way valve.When being the said outlet pipeline break-make of said water side solenoid control, also can control the break-make of said drain water circuit, in the time of the said inlet pipeline break-make of said water inlet end magnetic valve (2) control, also can control the break-make of said drain water circuit.
The utility model gas heater is following with the operation principle of automatic drainage device:
Gas heater with the work of automatic drainage device before, in master control substrate 5, preestablish the automatic drainage temperature value.
When gas heater is worked with the automatic drainage device, the temperature of water in the said temperature sensor 3 detecting real-time water pipelines, and be transferred to said master control substrate 5; The temperature that the said temperature sensor 3 of said master control substrate 5 perception transmits, and compare with predefined automatic drainage temperature value, when reaching the control temperature requirement; Give water side magnetic valve 1 and 2 energisings of water inlet end magnetic valve respectively, water side magnetic valve 1 will go out respectively with water inlet end magnetic valve 2/and the water inlet end water route closes, and opens drain water circuit; Water in the water tank water pipeline is discharged by discharge opening 4 automatically; After accomplishing sluicing, water side magnetic valve 1 postpones to cut out after the several seconds with water inlet end magnetic valve 2 again, at this moment; Water route, water side, water inlet end water route and drain water circuit are all closed condition, to guarantee subnormal use down.
Under the gas heater during subnormal use; Said master control substrate 5 is given water side magnetic valve 1 and 2 energisings of water inlet end magnetic valve respectively; Water side magnetic valve 1 will go out respectively with water inlet end magnetic valve 2/unlatching of water inlet end water route; And this moment, drain water circuit was in closed condition, can not influence the normal use of gas heater.
Claims (2)
1. a gas heater is used the automatic drainage device; Comprise inlet pipeline, outlet pipeline, drain water circuit and master control substrate (5); It is characterized in that: said drain water circuit is provided with discharge opening (4); The infall of said drain water circuit and said outlet pipeline is provided with water side magnetic valve (1); The infall of said drain water circuit and said inlet pipeline is provided with water inlet end magnetic valve (2), and at least one place is provided with temperature sensor (3) on said inlet pipeline, outlet pipeline and the drain water circuit, and said water side magnetic valve (1), said water inlet end magnetic valve (2) and said temperature sensor (3) electrically connect with said master control substrate (5) respectively.
