Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] This embodiment provides a zero-cold water gas water heater built-in water pump anti-blocking control method, such as figure 2 As shown, the method includes the following steps:

[0032] S1, the zero cold water gas water heater is energized, and the cumulative stop running time t of the built-in water pump is collected;

[0033] S2. Judging whether the accumulative stop running time t satisfies the condition for the zero-cooled gas water heater to perform anti-sticking operation; if not, return to S1; if yes, clear the accumulative stop running time t, and proceed to S3;

[0034] S3. The built-in water pump u...

Abstract

The invention belongs to the technical field of zero-cold water gas water heaters, and discloses a control method for preventing a stuck water pump of a built-in water pump of a zero-cooled water gas water heater. condition; if so, the accumulated stop running time t is cleared, and the built-in water pump starts at the first power threshold P 0 Start, detect the instantaneous speed V of the built-in water pump after the first time threshold of operation 0 Is it satisfied: V 0 >First speed threshold V 0 ’; if not, the built-in water pump will use the second power threshold P 1 Running, detect the instantaneous speed V of the built-in water pump after running the third time threshold 1 Is it satisfied: V 1 >Second speed threshold V 1 ’; if not, after the built-in water pump runs at the rated power P for the fifth time threshold, the zero-cooled gas water heater exits the anti-seize state. The method of the invention can start the built-in water pump with low power, not only can solve the stuck problem, but also reduce noise.

Description

technical field [0001] The invention belongs to the technical field of zero-cold water gas water heaters, and in particular relates to a control method for preventing a stuck water pump built into a zero-cold water gas water heater. Background technique [0002] Such as figure 1 As shown, after the zero-cold water gas water heater starts the zero-cold water function, the built-in water pump of the water heater will start. After starting, the water in the hot water pipeline will flow, flow out through the outlet pipe of the water heater, and the outflowing water will flow back to the water heater through the return pipe. A circulation pipeline is formed. After the water heater detects a water flow signal, it starts the burner. Usually, after 3-5 minutes of water circulation, all the water in the circulation pipeline can be heated to the temperature set by the user. Hot water, no cold water coming out first, ie "zero" cold water. [0003] That is to say, the built-in water p...
