The invention discloses a zero cold water control system. The zero cold water control system comprises a gas water heater body, a direct current water pump, a temperature sensing device, a gas controlvalve, a displayer and a controller, wherein the direct current water pump, a water flow sensing device, the temperature sensing device, the gas control valve and the operation displayer are all electrically connected with the controller, and the system further comprises the water flow sensing device; the water flow sensing device is arranged on a main water path of the gas water heater body, andthe water flow sensing device is used for monitoring the water flow flowing through the main water path in the gas water heater body in real time; the temperature sensing device is installed at the water inlet end of the water heater body; the gas control valve is installed in a gas supply passage in the gas water heater body and can control on and off of the gas; and the controller is used for changing the working current of the direct current water pump and controlling the rotating speed of the direct current water pump. According to the zero cold water control system, the direct current water pump is started according to the maximum working current, the water resistance is overcome, the circulating flow can quickly reach the starting flow, and normal startup preheating is ensured.
Description
technical field [0001] The invention relates to the field of electrical appliances, in particular to a zero cooling water control system and method. Background technique [0002] At present, zero-cold water gas water heaters have become the trend of the water heater industry because they can realize instant hot water, and are more and more popular among consumers. Such as figure 2 As shown, when the preheating function is activated, the built-in circulation pump of the zero-cold water gas water heater operates to drive the water stored in the external hot water pipe and return pipe to circulate and realize preheating. [0003] Old houses on the market are retrofitted with zero-cold water gas water heaters. Due to the excessive resistance of the circulation pipeline, there are many faults that cannot be turned on and heated after the pump is turned on for preheating, and cannot be preheated normally. In order to overcome this problem, most zero-cooled water gas water heater...
