Fuel gas water heater and control method thereof

Abstract

The invention relates to the field of water heaters, in particular to a fuel gas water heater and a control method thereof. The fuel gas water heater comprises a heater body and a burner, a soundproofchamber is arranged between the outer wall and the inner wall of the heater body, the burner is located inside the heater body, the top of the burner is provided with a combustion chamber, a sensibleheat exchanger is arranged above the combustion chamber, and a smoke guiding mechanism is arranged above the sensible heat exchanger, a cyclic utilization bin is arranged in the heater body, and thesmoke guiding mechanism communicates with the soundproof chamber through the cyclic utilization bin; and a plurality of water inlet pipes are arranged in the cyclic utilization bin, the upper and lower ends are each provided with a flow guide cover, each flow guide cover communicates with the corresponding water inlet pipes, the flow guide cover at the upper end of the cyclic utilization bin communicates with the input end of the sensible heat exchanger, the output end of the sensible heat exchanger is provided with a flow dividing system, and a first temperature sensor and a second temperature sensor are arranged in the flow dividing system and the cyclic utilization bin correspondingly. By means of the fuel gas water heater and the control method, corresponding adjustment can be dynamically carried out according to the real-time temperature, the temperature keeps in the normal state under the condition of the low energy consumption, energy saving and environmental protection are achieved, meanwhile, noise is low, and the comfort is strong.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a gas water heater and a control method thereof. Background technique [0002] At present, there is a certain market demand for household heating stoves in northern my country; when the existing gas water heaters use the bathing function, the water temperature will rise rapidly, which will affect the heating temperature in the heating pipes, and cause the temperature in the user's room to gradually increase. increase, so it affects the optimal heating temperature value in the room, and when the existing water heater is working, it will produce working noise, which will affect the work and rest of other people in the room at night; and many people often forget Turn off the bathing function, which will cause conflicts with the heating system, and the gas feed cannot be controlled in time. At the same time, more importantly, the main heating source of the existing gas water heaters comes ...

[0002] At present, there is a certain market demand for household heating stoves in northern my country; when the existing gas water heaters use the bathing function, the water temperature will rise rapidly, which will affect the heating temperature in the heating pipes, and cause the temperature in the user's room to gradually increase. increase, so it affects the optimal heating temperature value in the room, and when the existing water heater is working, it will produce working noise, which will affect the work and rest of other people in the room at night; and many people often forget Turn off the bathing function, which will cause conflicts with the heating system, and the gas feed cannot be controlled in time. At the same time, more importantly, the main heating source of the existing gas water heaters comes from the temperature in the combustion chamber and the sensible heat. The converter is used for supply, and dynamic monitoring cannot be performed to adjust the input amount of natural gas fed to the proportional valve, so it is not enough to maximize energy saving, and this problem will lead to an increase in gas costs
