Abstract

The invention discloses an energy-saving and safe socket of an electrical appliance and belongs to the technical field of electrical appliances. The damage of the electrical appliance generally occurs during a switch-on state and a switch-off state, because at the instant that a power supply switch is on, great impact electricity is generated by the electrical appliance, the switch generates obvious arc discharge, and the discharge forms severe threat to the safety of the electrical appliance; addition, multiple people do not shut the electrical appliance when leave, unnecessary waste is caused. Aiming at the situations, the scheme provided by the invention adopts the following measures: a switch on a socket panel is replaced by a zero crossing solid-state relay; an infrared receiving alarm device is installed on the socket and alarm signals output by the infrared receiving alarm device trigger a circuit through driving to control the connection and disconnection of the zero crossing solid-state relay; and the infrared receiving alarm device actively shuts the electrical appliance connected to the socket when a master is not in, thus the unnecessary waste of the electricity energy is eradicated, and the safety hazard is eliminated.

Description

The electric appliance energy-saving safety socket

Technical field

The present invention is a field of security appliance technology.

Background technology

AC Power supply socket is one of the most frequent at most electrical equipment of our daily life contact.Believing mostly had such experience, can see flash of light that spark is arranged in the switch and the explosive sound of hearing spark when opening or closing the switch on the AC Power supply socket.Being easy to then take place phone in this case can automatic hands-free off-hook, and the image of DTV can pause or occur mosaic, also has a lot of friends to reflect that good electrical equipment today yesterday is once starting shooting bad or the like.These all phenomenons all are that electrical appliance has produced very big impulse current between Shun of mains switch because we open or close; Produce HTHP when making on the contact of switch Shun and produced tangible arc discharge after the air ionization of periphery; Produced powerful electromagnetic pulse toward the contact meeting in this case above-mentioned simultaneously, it disturbs the normal operation of other electrical equipment.We be unable to do without semiconductor device by various household electrical appliance used in everyday, and the maximum shortcoming of semiconductor device is to bear the ability extreme difference of big electric current, high voltage impact, can not show a candle to vacuum device.So above-mentioned physical phenomenon has constituted serious threat to the safety of our household electrical appliance.Moreover when arc discharge occurring in the switch, the contact that electric arc can serious ablation switch makes their produce oxidation and the electric conductivity of switch is further descended, and can generate heat when serious to dissolving even can cause fire.This never is sensational, Here it is irrefutable evidence that the annual fire that causes because of electricity is countless.

In addition in our daily life much human particularly child to make a mistake through regular meeting be exactly that various electrical equipment are just opened in a return home, when the service range of leaving these electrical equipment did not afterwards need them, but they were not turned off with handgrip.Caused the waste of the energy, also brought hidden danger simultaneously to safety.

Summary of the invention

To the problems referred to above, this programme has taked some measures to overcome.At first, infrared ray is installed on socket is received warning device and control the break-make of zero-cross solid state relay through driving circuits for triggering by the alarm signal of its output with the mains switch on the alternative socket panel of zero-cross solid state relay.The switch of socket all carries out in the alternating current zero passage like this, so can not produce the situation that impulse disturbances more can not produce arc spark and ablation contact.The infrared ray of installing simultaneously receive warning device owner not the time can initiatively close the electrical equipment that is connected on the socket, also eliminated this potential safety hazard thereby stopped the unnecessary waste of electric energy.

Description of drawings

Fig. 1, infrared ray receive warning device output signal flow journey figure.

The physical phenomenon of some above-mentioned band harmfulness all is to be caused by electric current in the circuit and voltage jump, as long as we eliminate the generation that the curtage of this sudden change just can be avoided the physical phenomenon of above-mentioned these band harmfulness.We know that the AC power electricity is a kind of the variation in time and the power supply that changes, when have tens voltage and currents to be zero each second in its circuit.This programme uses a kind of zero-cross solid state relay, and it is zero to realize when being so-called zero passage that the break-make of this device all designs voltage at alternating current.As long as device for switching when utilizing the alternating current zero passage, switch so each time, electric current in the circuit and voltage all are zero-based, also end at zero, thereby have eliminated the phenomenon of voltage and current sudden change, have also eliminated these above-mentioned bad phenomenon.

For electrical energy saving this programme infrared ray has been installed in socket and has been received warning device, be used to receive the infrared ray that human body sends.This installs when detection is left less than human body in its investigative range, can be with the form prompting owner of sound or light in the regular hour.Later its lead-out terminal has an alarm signal or delayed alarm signal during this period of time.These blackouts when detecting human body again.This programme is exactly this function of utilizing it, the signal of its output through driving the break-make of circuits for triggering control zero-cross solid state relay, thereby realize owner in that then power supply is logical, owner's then function of power-off of leaving.

Concrete signal flow is that the signal of infrared ray output is delivered to the driving circuits for triggering, and the break-make that circuits for triggering control zero-cross solid state relay according to the state of this signal is as shown in Figure 1 by driving.Be connected with hand control switch on the circuits for triggering and be used for manually opened supply socket driving for bearing special requirement, break away from the control that infrared ray receives warning device.

Claims

1. electric appliance energy-saving safety socket; Comprise that mainly infrared ray receives warning device, zero-cross solid state relay, driving circuits for triggering; It is characterized in that, infrared ray is installed on socket is received warning device and control the break-make of zero-cross solid state relay through driving circuits for triggering by the alarm signal of its output.
