Abstract
The utility model relates to a hot air type anti-freezing protective device of a water pipe of a gas water heater, whose main technical characteristics are that the device comprises a normal close type thermoregulator, a PTC heater and a normal open thermoregulator, wherein the normal close type thermoregulator and the normal open thermoregulator are respectively and electrically linked with a power supplying circuit of the gas water heater, the normal open type thermoregulator is arranged on the water pipe of a heat exchanger of the gas water heater, the PTC heater is arranged on a fan of the gas water heater, and the normal close thermoregulator is arranged on an outer shell of the PTC heater. The utility model has the characteristics of effectively preventing water which is remained in the water pipe of the heat exchanger from freezing and preventing hidden troubles of damaging the water pipe due to expansion and the like.
Description
Technical field: the utility model relates to a kind of gas heater water pipe anti-freezing protective device.
Background technology: the gas heater shutdown of finishing using, the water that stays in the heat exchanger water pipe in the gas heater is static not to flow, when ambient temperature drops to the subcritical temperature, have following two kinds of situations to take place: a kind of to be that gas heater is placed on outdoor, and the water that stays in the heat exchanger water pipe in the gas heater freezes; It is indoor that another kind is that gas heater is placed on, and extraneous cold wind is blown into the water that stays in the heat exchanger water pipe directly to gas heater through exhaust fume collecting hood from the gas heater flue and freezes; Both of these case all can cause the hidden danger of the bad water pipe that expands, and for overcoming these defectives, gas heater water pipe anti-freezing protective device is developed.
Summary of the invention: technical problem to be solved in the utility model is that a kind of gas heater water pipe hot air type anti-freeze protection device will be provided, and it can prevent effectively that the water that stays in the heat exchanger water pipe from freezing, and avoids the hidden danger of bloated bad water pipe.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises closed type temperature controller, PTC heater, open type temperature controller, closed type temperature controller, open type temperature controller electrically connect with the power supply circuits of gas heater respectively, the open type temperature controller is installed in the heat exchanger of gas heater on the water pipe, PTC heater is installed on the blower fan of gas heater, and the closed type temperature controller is installed on the PTC heater shell.
Described PTC heater is installed on the air inlet of gas heater.
Described PTC heater is installed on the fan outlet of gas heater.
Described open type temperature controller is 1～3 ℃ of open type temperature controller.
Described closed type temperature controller is 65～90 ℃ of closed type temperature controllers.
Described open type temperature controller is 2 ℃ of open type temperature controllers.
Described closed type temperature controller is 75 ℃ of closed type temperature controllers.
The utility model is compared the beneficial effect that is produced with prior art:
1, because the anti-freeze protection device that the utility model adopts closed type temperature controller, PTC heater, open type temperature controller to constitute so it can prevent effectively that the water that stays in the heat exchanger water pipe from freezing, is avoided the hidden danger of bloated bad water pipe.
Description of drawings: Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
The specific embodiment: shown in accompanying drawing 1, open type temperature controller 5 is installed on heat exchanger 6 water pipes, and closed type temperature controller 1 is installed on the shell of PTC heater 3, places PTC heater 3 at blower fan 2 air inlets.
Perhaps referring to shown in the accompanying drawing 2, open type temperature controller 5 is installed on heat exchanger 6 water pipes, and closed type temperature controller 1 is installed on the shell of PTC heater 3, places PTC heater 3 at blower fan 2 air outlets.
Shown in accompanying drawing 1, accompanying drawing 2, closed type temperature controller 1, open type temperature controller 5 electrically connect with the power supply circuits of gas heater respectively, provide power supply by power supply circuits to it.Open type temperature controller 5 on being installed in gas heater heat exchanger 6 water pipes is sensed and can be moved connection when temperature is lower than 2 ℃, start blower fan 2 and PTC heater 3 work and hot blast is sent into the combustion chamber heat exchanger 6 is heated, and can not take place that the water in the water pipe freezes and the accident of the bad water pipe that expands in the heat exchanger 6.
