Built-in electric energy collection module of household appliance

Abstract

The invention discloses a built-in electric energy collection module of a household appliance. A power-switching circuit and a signal acquisition circuit of the built-in electric energy collection module are both connected with a microcontroller U1, and the microcontroller U1 is further connected with a communication circuit. The power-switching circuit is used for converting an alternating current power supply into direct currents, and provides a power supply for the signal acquisition circuit, the microcontroller U1 and the communication circuit. The signal acquisition circuit carries out voltage sampling and current sampling on the power supply signals of the household appliance. The microcontroller U1 is used for receiving a voltage sampling value and a current sampling value sent by the signal acquisition circuit, calculating a voltage effective value, a current effective value, an electric energy value, active power, reactive power and a power factor, and sending a calculated result to the communication circuit. The communication circuit is used for sending the calculated result to a target object at regular intervals. The built-in electric energy collection module of the household appliance has the advantages of being capable of monitoring the electric parameters of the household appliance, and enabling consumers to obtain the electricity consumption information of the household appliance conveniently.

Description

technical field [0001] The invention relates to a built-in electric energy collection module of a household appliance. Background technique [0002] With the development of social economy, people's living standards are getting higher and higher, and all kinds of household appliances are constantly emerging, entering thousands of households, such as refrigerators, washing machines, air conditioners, microwave ovens, etc. Life brings convenience and improves people's quality of life. With the increase of household appliances, the user's electricity bill has also increased significantly, and the electricity bill of several hundred yuan is consumed unconsciously every month. [0003] At present, the existing electrical equipment usually only indicates its own power consumption in the model identification, or expresses the unit power consumption in the form of energy consumption level, and there is no special metering module to monitor the power consumption of household applianc...

Problems solved by technology

[0003] At present, the existing electrical equipment usually only indicates its own power consumption in the model identification, or expresses the unit power consumption in the form of energy consumption level, and there is no special metering module to monitor the power consumption of household appliances. Consumers cannot obtain electricity consumption information of household appliances, and users cannot intuitively and real-time understand the power consumption of each electrical equipment

Users can only know the total electricity consumption through the total electricity meter, but cannot know the electricity consumption of each household appliance, which is not conducive to saving electricity
