Fuel gas energy-saving water boiler

Abstract

The invention relates to a fuel gas energy-saving water boiler. The fuel gas energy-saving water boiler comprises an upper water tank, a lower water tank, a heat exchanger, a combustion chamber and a condenser pipe. A smoke outlet pipe is installed in the condenser pipe and communicates with the heat exchanger; and a first water outlet and a first water inlet are formed above and below the condenser pipe correspondingly. The fuel gas energy-saving water boiler further comprises a first water inlet pipe and a second water inlet pipe; one end of the first water inlet pipe is externally connected with a water source, and the other end of the first water inlet pipe is connected with the first water inlet; and one end of the second water inlet pipe is connected with the first water outlet, and the other end of the second water inlet pipe communicates with the lower water tank. The fuel gas energy-saving water boiler has the beneficial effects that by installing two water tanks, after the water in the lower water tank is boiled, water is injected into the lower water tank, the hot water enters into the upper water tank under the effect of pressure, separation of heat preservation and heating is achieved, repeatedly boiled water does not occur, and the water is safe and healthy; and in addition, the cold water guided into the lower tank water passes through the condenser pipe to absorb heat energy of discharged smoke and gas in a smoke outlet pipe, preheating of the cold water is achieved, the heating time is shortened, and the effects of energy saving and environment protecting are achieved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a gas-fired energy-saving water boiler. Background technique [0002] The existing water boiler connected to the tap water pipeline through the water inlet first injects cold water into the heating water tank with an electric heater to make the cold water boil, and when a certain amount of boiling water in the heating water tank is taken, then inject cold water Replenish and reheat, and in order to maintain the water temperature, the electric heater will repeatedly boil the boiling water in the water tank, which consumes a lot of power and takes a long time to heat up, and the water quality in the water tank will deteriorate after repeated boiling, which will easily affect the human body healthy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gas energy-saving water boiler, which solves the problem th...
