The invention discloses a circulating pump control circuit and a circulating pump. The circulating pump control circuit comprises a Hall device, a power conversion module and a central control module, and the central control module carries out data transmission after carrying out analog-digital processing on temperature sampling signals and pulse signals of the Hall device and a temperature sensor. The circulating pump control circuit is applied to linkage work of the water heater. The circulating pump control circuit is arranged on a water inlet / outlet pipeline of a water heater and used for pressurizing circulation. The control circuit is connected with a main control board of the water heater and used for processing pulse signals of the Hall device and temperature sampling signals of the temperature sensor, and data are transmitted to the main control board of the water heater after analog-digital processing; and meanwhile, an instruction of the main control board of the water heater is received and transmitted to a motor of the circulating pump after being processed, data receiving and transmitting work is achieved, and accurate collection and transmission of data are achieved. According to the circulating pump, modularization and integration are achieved, the assembly process is simplified, and the cost is saved. The circulating pump control circuit realizes small distortion of sampling data, so that the monitoring data of temperature and water flow are more accurate.
Description
technical field [0001] The invention relates to a circulating pump control circuit and a circulating pump. Background technique [0002] Water heaters currently on the market are equipped with water pumps for control and regulation of water supply pressure and hot water circulation. This type of water pump is generally a miniature water pump, which is linked with the water heater when working. In the past, this type of miniature water pump was basically equipped with a Hall module and a temperature sensor module. The Hall module and the temperature sensor module are usually connected to the control circuit board of the water heater through a corresponding independent connection harness for signal feedback and water pump control. However, there are connection restrictions in the connection harness, and the assembly method and assembly position of the water pump are limited; moreover, the signal is basically an analog signal, the transmission accuracy of the signal is not ide...
