Abstract

The invention discloses a self-adaptive temperature-controlling zero-cold water gas water heater. The water heater comprises a zero-cold water gas water heater body, a built-in water pump, a water outlet temperature detection module, a water inlet temperature detection module, a gas control valve, an operation display module and an environment temperature detection module, wherein the built-in water pump, the water outlet temperature detection module, the water inlet temperature detection module, the gas control valve, the operation display module and the environment temperature detection module are electrically connected with a controller. The invention further discloses a control method of the water heater. The method comprises the following steps that a preheating mode is started; preset temperature Tpreset, water inlet temperature Twater inlet, and mounting environment temperature Tenvironment are detected; whether the preset temperature Tpreset satisfies the condition that Tpresetis larger than Tpreheating max or not is judged; if not, stored water temperature of a circulating pipeline is controlled according to the preset temperature Tpreset; and if yes, after the Tpreset isautomatically adjusted to target preheating temperature Ttarget according to the Twater inlet or the Tenvironment, then the stored water temperature of the circulating pipeline is controlled according to the target preheating temperature Ttarget. According to the self-adaptive temperature-controlling zero-cold water gas water heater and the control method thereof, the problem that existing storedwater temperature in the circulating pipeline is too high can be solved.

Description

technical field [0001] The invention belongs to the technical field of zero-cold water gas water heaters, and in particular relates to an adaptive temperature-controlled zero-cold water gas water heater and a control method thereof. Background technique [0002] At present, the zero-cold water gas water heater has become a trend in the water heater industry because it can realize instant hot water. The water stored in the outlet pipe and the return pipe is pumped back to the zero cold water gas water heater for preheating, forming a preheating circulation pipeline to realize preheating. [0003] During the preheating process, the zero cold water gas water heater adjusts the firepower according to the deviation between the outlet water temperature and the preset temperature, so that the outlet water temperature reaches the preset temperature. The preset temperature setting range of gas water heaters is generally 35°C to 60°C. When the preset temperature of the zero-cold wat...
