Abstract
The utility model discloses a safety water heater comprising a main heat exchanger. The main heat exchanger is provided with a cold water heating pipe, the top of the main heat exchanger is provided with an air exchanging pipeline, and a part of the cold water heating pipe, which is adjacent to air exchange pipeline, is provided with a heat exchanger for cooling air; an air feeding and collecting hood is arranged between the air exchange pipeline and the heat exchanger for cooling air. The fresh air enters the fresh air inputting pipeline from a fresh air suction opening, and the fresh air makes the heat exchange with a high-temperature flue gas exhausting pipeline; the fresh air is quickly heated up, and the air feeding and collecting hood concentrates the high-temperature air; the high-temperature air is forced to flow to the heat exchanger for cooling air, is cooled by the cold water entering into the water heater just now, and enters the water heater then, therefore the temperature of the air is lowered, and the inside parts of the water heater can not be damaged.
Description
Technical field
The utility model relates to a kind of water heater, relates in particular to a kind of water heater that can cool off the fresh air that enters water heater.
Background technology
Existing water heater structure comprises a main heat exchanger, and this main heat exchanger is equipped with a cold water heating tube, and this cold water heating tube one end is a cooling water inlet, and an end is a hot water outlet, and after cold water entered the cold water heating tube, main heat exchanger work to the cold water heating, made its intensification.Flow out from hot water outlet then.Described heat exchanger also comprises gas-operated thermal bath facility and blower fan.During heat exchanger work, the combustion gas in the gas-operated thermal bath facility is lighted, and simultaneously, blower fan work is fully burnt combustion gas.Described water heater top is equipped with air refreshing tube, and this air refreshing tube comprises a high-temperature flue gas discharge tube, and this high-temperature flue gas discharge tube one end is connected with described heat exchanger, and an end is equipped with flue gas discharge opening; The high-temperature flue gas that described gas-operated thermal bath facility burning produces emits by described fume emission pipeline, flue gas discharge opening.Described fume emission pipeline periphery is surrounded with the fresh air input channel, this fresh air input channel one end is connected with described heat exchanger, one end is equipped with the fresh air suction inlet, fresh air enters the fresh air input channel from the fresh air suction inlet, fresh air and described high-temperature flue gas discharge tube carry out heat exchange, and fresh air heats up rapidly, after the fresh air of high temperature enters water heater, control part to water heater inside forms high temperature damage, influences the safety in utilization of water heater.
The utility model content
At above-mentioned deficiency, the purpose of this utility model provides a kind of water heater safe in utilization that can lower the temperature to the high temperature fresh air that sucks.
For achieving the above object, the utility model is by the following technical solutions: the water heater that the utility model is safe in utilization, comprise a main heat exchanger, this main heat exchanger is equipped with a cold water heating tube, described main heat exchanger top is equipped with air refreshing tube, described cold water heating tube is equipped with air cooled heat exchanger near the part of described air refreshing tube, is equipped with the air inlet gas skirt between described air refreshing tube and the described air cooled heat exchanger.
Described air refreshing tube comprises a high-temperature flue gas discharge tube, and this high-temperature flue gas discharge tube one end is connected with described main heat exchanger, and an end is equipped with flue gas discharge opening; Described fume emission pipeline periphery is surrounded with the fresh air input channel, and this fresh air input channel one end is equipped with the fresh air suction inlet, and an end is communicated with described air inlet gas skirt.
Fresh air enters the fresh air input channel from the fresh air suction inlet, fresh air and described high-temperature flue gas discharge tube carry out heat exchange, fresh air heats up rapidly, described air inlet gas skirt puts together high temperature air, pressure flows to air cooled heat exchanger, with the cold water that just enters water heater the high temperature fresh air is cooled off, and then enters into water heater inside, the temperature of air is lowered the temperature like this, can the part of water heater inside not worked the mischief.
