Problems solved by technology

However, this method has a limited effect on improving the temperature rise of water cut-off. When there is a relatively high temperature rise of water cut-off, it still fails to reduce the temperature rise of water cut-off, and this method cannot solve the problem of water cut-off temperature drop.

Abstract

The invention discloses a control method for reducing the temperature rise and drop of water cut-off temperature of a water heater, the water heater and a device. The water heater comprises a heat exchanger, a preheating heat exchanger and a combustor, the heat exchanger is connected with a water inlet pipe and a water outlet pipe, and the water inlet pipe is provided with a first water inlet branch provided with a first water inlet control valve and a second water inlet branch provided with a second water inlet control valve. The first water inlet control valve is opened at a first valve opening degree; when the water cut-off time is larger than or equal to the first preset time and smaller than the second preset time, the valve is opened at the second valve opening degree; and when the water cut-off time is larger than or equal to the second preset time, opening is conducted at the third valve opening degree. According to the control method, by arranging the preheating heat exchanger, the problems of water stop temperature rise and water stop temperature drop of the water heater can be solved, the amount of cold water for heat exchange with hot water is correspondingly adjusted by adjusting the valve opening degree of the first water inlet control valve, and the constant-temperature performance of hot water can be better maintained.

Description

technical field [0001] The present invention relates to the technical field of water heaters, and in particular, to a control method for reducing the temperature rise and drop of water when the water heater is stopped, a computer-readable storage medium, and a water heater. Background technique [0002] During the use of the water heater, when the water is turned off in the middle, the residual heat continues to heat the water in the heat exchanger tube, resulting in the problem of water temperature rise and water temperature drop when the water heater is turned on again, which is easy to burn users and affect the use experience of the water heater. How to reduce the temperature rise and temperature drop of the water outage is a common concern in the industry. [0003] For the problem of temperature rise when the water is stopped, at present, a bypass pipe is generally added to the heat exchanger or a bypass pipe is added at the inlet and outlet to reduce the temperature ris...
