Abstract
An antifreezing gas water heater is disclosed by the utility model, which comprises a high-power exhaust fan and a heat exchanger arranged in a gas water heater encloser. Temperature controllers are arranged on both sides of top of a siphonal heat exchanger and are connected with the high power exhaust fan and a power supply in series to form an electric circuit. When outdoor cold air exerts effect on the heat exchanger through a purge duct, and temperature of accumulated water in a pipeline of the heat exchanger is reduced near freezing point, the temperature controller begins to work and is connected to the circuit of the high-power exhaust fan; the exhaust fan will exhaust indoor hot air outdoors through the heat exchanger. In this way, outdoor cold air is prevented from entering the water heater through the purge duct and the heat exchanger is also heated so as to resist freeze. Only two temperature controllers are added in the utility model comparing with prior gas water heaters; the utility model is not only simple in structure but also low in cost of manufacture, works safely with low failure rate, is easy to maintained, and can effectively prevent the gas water heater from being frozen, and have excellent antifreezing effect when used in winter.
Description
Technical field
The utility model belongs to the improvement of gas heater structure, particularly antifreeze gas heater.
Background technology
Wide geographic area in northern China, winter, cold was very long, night, outdoor temperature was lower, because the smoke exhaust pipe of gas heater outdoor, is incorporated into outdoor cold air on the heat exchanger of machine intimate easily by smoke exhaust pipe, the icing bad heat exchanger pipeline that will expand that under low-temperature condition, expands of the water in the heat exchanger, maintenance difficult not only, the maintenance cost height, and often cause very big economic loss to the user, serious also can cause human casualty accident.Though there is producer to design various hurricane globes or increase electric heater unit, still the phenomenon that gas heater is damaged by frost can appear sometimes, and cause gas heater to leak, antifreezing effect is reliable inadequately.
The utility model content
The purpose of this utility model is to provide a kind of antifreeze gas heater, and is not only simple in structure, and cheap for manufacturing cost, can prevent effectively that gas heater is damaged by frost, good freezing protection effect.
The purpose of this utility model is achieved in that a kind of antifreeze gas heater, comprise the Forced discharge fan and the heat exchanger that are installed in the gas heater housing, in the both sides, heat exchanger top that are connected with bend pipe temperature controller is being set respectively, two temperature controllers are cascaded with Forced discharge fan and power supply respectively and constitute electric loop.
Because wide geographic area in northern China, though winter is cold very long, outdoor temperature is low, but indoor temperature generally can remain on more than 10 degrees centigrade, when outdoor cold air acts on the heat exchanger by smoke exhaust pipe, when making ponding temperature in the heat exchanger pipeline be reduced near the freezing point, the temperature controller that is arranged on both sides, heat exchanger top just begins action, connect the Forced discharge fan circuit, be discharged into the hot-air of the inside, house outdoor by heat exchanger by Forced discharge fan, when the blocking-up outdoor cold air enters water heater inside by smoke exhaust pipe, also heated heat exchanger like this, improved the temperature of heat exchanger, thereby reached antifreeze purpose.After the temperature of heat exchanger raise, temperature controller will automatic disconnection, cut off the circuit of Forced discharge fan, and Forced discharge fan quits work.
The utility model has only increased by two temperature controllers, and is not only simple in structure, and cheap for manufacturing cost, reliable operation, and fault rate is low, is easy to safeguard that can effectively prevent gas heater be damaged by frost, good freezing protection effect when using winter.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is that master of the present utility model looks the partial structurtes schematic diagram.
The specific embodiment
A kind of antifreeze gas heater, as shown in drawings, comprise the Forced discharge fan 5 and the heat exchanger that are installed in the gas heater housing 1, in the both sides, heat exchanger top that are connected with bend pipe 4 temperature controller 3,6 is being set respectively, two temperature controllers 3,6 should be installed in the position of close gas heater fume extractor 2 as far as possible, can perceive at first like this by fume extractor 2 and enter into the variations in temperature that cold air brought in the water heater, improve the sensitivity of work.Two temperature controllers 3,6 are cascaded with Forced discharge fan 5 and power supply respectively and constitute electric loop.Two temperature controllers 3,6 can also can move by single movement simultaneously, and any one temperature controller action can startup Forced discharge fan 5 rotates, thereby improves the reliability of work.The temperature controller of action can improve antifreezing effect so effectively when temperature controller 3,6 was 2 ℃～5 ℃, guaranteed that gas heater can round-the-clock normal use.
Claims (2)
1, a kind of antifreeze gas heater, comprise the Forced discharge fan (5) and the heat exchanger that are installed in the gas heater housing (1), it is characterized in that: in the both sides, heat exchanger top that are connected with bend pipe (4) temperature controller (3,6) is being set respectively, two temperature controllers (3,6) are cascaded with Forced discharge fan (5) and power supply respectively and constitute electric loop.
2, antifreeze gas heater according to claim 1 is characterized in that: the temperature controller of action when temperature controller (3,6) is 2 ℃～5 ℃.
