Abstract
The utility model discloses a multifunctional electricity saving socket based on LCD display. The multifunctional electricity saving socket comprises an electric socket body. A main control circuit and a number of sockets are arranged in the electric socket body. The sockets are connected with a 220VAC power supply through an electric control switch. A current transformer is used for sensing current passing through the sockets, and connects a current signal and the main control circuit. The electric control switch is controlled by the main control circuit. The main control circuit is powered by the 220VAC power supply. The main control circuit is connected with an LCD display and a number of selection switches. Through the selection switches and the LCD display, a timing output socket, a standby electrical appliance socket and a common electrical appliance socket can be preset. The LCD display can display voltage and time and the current, the power and the power quantity of each socket. Time displayed by the LCD display comprises a clock, timing time, the use time of an electrical appliance and the like. The multifunctional electricity saving socket provided by the utility model has the advantages of complete functions, wide application range, excellent performance and obvious energy saving.
Description
Technical field
The utility model relates to a kind of multifunctional power saving socket showing based on LCD, relates in particular to a kind ofly by LCD, to show voltage, power, time, electric weight, economizes on electricity, the electrical socket of timing function.
Background technology
In prior art, most of household electrical appliance can produce standby power in use, for example television set, air-conditioning, only depend on remote controller powered-down, often electrical equipment itself can produce the standby power of tens watts, can cause waste to electric energy like this, avoids the generation of this situation, can only close the switch of socket, or pull out the attaching plug of electrical equipment, in daily life, people often can not operate like this, in order to overcome above-mentioned phenomenon, emerged in large numbers on the market very eurypalynous electricity-saving socket.Principle is roughly the same, utilizes inductance transformer, switches on or off the power supply of power consumption equipment by comparing the curent change of power consumption equipment under start or holding state, makes the complete power-off of power consumption equipment, without standby power, produces.But the shortcoming of this electricity-saving socket is no-voltage, electric current, power measurement and Presentation Function, also without timing function.User does not know the actual in electrical power consumed of electrical equipment, is unfavorable for the propelling of energy-saving and emission-reduction.
