Fuel gas rapid water heater with automatic water mixing device

Abstract

The invention discloses a fuel gas rapid water heater with an automatic water mixing device. The fuel gas rapid water heater comprises the automatic water mixing device connected at the water outlet end of the fuel gas rapid water heater. The automatic water mixing device comprises two water flow branches, a first temperature sensor, a first water proportional valve, a second water proportional valve, a second temperature sensor, a water storage tank, a third temperature sensor and a controller. A three-way joint is connected at the water outlet end of the fuel gas rapid water heater; one end of the three-way joint is connected with the water inlet end of the water storage tank, and the other end of the three-way joint is connected with one of the water proportional valves; the water outlet end of the water storage tank is connected with the other water proportional valve; the water proportional valves are utilized to adjust the magnitude of the water amount, and the water storage tank neutralizes the water mixing ability; the water temperature fluctuation caused at the time of starting again and changing of the water amount is solved fundamentally while hot water flows out rapidly; and the problem of the fuel gas rapid water heater is solved effectively, performance of the fuel gas rapid water heater is improved, and developing of the fuel gas rapid water heater is facilitated.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to a gas instant water heater with an automatic water mixing device. Background technique [0002] The gas instant water heater can produce hot water immediately after being ignited, has a simple structure and a small size, and is currently used by most families. However, people have the habit of washing their hair, face, brushing their teeth, and applying body soap when they take a bath. Since the gas instant water heater needs a series of start-up sequences, cold water will be poured in, resulting in "hot and cold" Phenomenon. In addition, when the water volume changes, the gas instant water heater will have water temperature fluctuations. [0003] Aiming at the problem of hot and cold outlet water temperature when the gas instant water heater is turned on, the main solution in the prior art is to add a water tank to the water outlet of the gas instant water heater.

However, people have the habit of washing their hair, face, brushing their teeth, and applying body soap when they take a bath. Since the gas instant water heater needs a series of start-up sequences, cold water will be poured in, resulting in "hot and cold" Phenomenon

In addition, when the water volume changes, the gas instant water heater will have water temperature fluctuations.

[0003] Aiming at the problem of hot and cold outlet water temperature when the gas instant water heater is turned on, the main solution in the prior art is to add a water tank to the water outlet of the gas instant water heater. Since the cold water in the water tank needs to be discharged in advance, not only the heating speed of the start-up Slow and wastes water resources

At the same time, the existing technology does not have a good solution to the temperature change caused by the fluctuation of water volume
