Problems solved by technology

However, the water in the pipeline of the water heater is continuous. In order to save water, the user will often turn off and on the water heater during the bathing process. After each shutdown, the water remaining in the pipeline will gradually cool down. When it is turned on for the first time, the cold water left in this part will initially come out, and then the heated hot water will come out, and the cold water will be released, resulting in waste
Furthermore, the change of the initial temperature of the cold water entering the water heater and the change of the water pressure will cause the change of the water flow rate to cause a large fluctuation of the outlet water temperature, resulting in poor bathing effect for the user.

Abstract

The invention discloses a gas water heater and a control method thereof. The gas water heater comprises a shell, a heat exchange device, a liquid storage tank and a control device. The shell is provided with a raw water inlet and a hot water outlet. The heat exchange device is arranged in the shell and provided with a heat exchange water inlet and a heat exchange water outlet, and the heat exchange water inlet is connected with the raw water inlet. The liquid storage tank is arranged in the shell and provided with a liquid storage water inlet and a liquid storage water outlet. The liquid storage water inlet is connected with the heat exchange water outlet. The liquid storage water outlet is connected with the hot water outlet. The control device is arranged in the shell so as to control the heat exchange device. According to the gas water heater, the temperature of hot water flowing out of the hot water outlet can be stable, the phenomenon of sudden hot and cold is avoided, and the comfort level of a user is improved.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a gas water heater and a control method thereof. Background technique [0002] At present, the heating principle of gas water heaters on the market is that after the cold water flows through the heat exchange device through the water heater inlet and is heated, it can provide users with fast hot water. However, the water in the pipeline of the water heater is continuous. In order to save water, the user will often turn off and on the water heater during the bathing process. After each shutdown, the water remaining in the pipeline will gradually cool down. When it is turned on for the first time, the cold water left in this part will initially come out, and then the heated hot water will come out, and the cold water will be drained, resulting in waste. Furthermore, the change of the initial temperature of the cold water entering the water heater and the change of the water ...
