Abstract
The utility model relates to an energy saving device for household electric appliances, particularly to an energy saving infrared switch. The infrared switch comprises an infrared receiving circuit, a control circuit of a single chip microcomputer, an output circuit, a power supply circuit and a current sampling circuit. The power supply circuit is connected with the infrared receiving circuit, the control circuit of the single chip microcomputer and the output circuit. The control circuit of the single chip microcomputer is connected with the infrared receiving circuit, the output circuit and the current sampling circuit. The current sampling circuit comprises a current transformer, a resistor and a capacitor. Due to the adoption of the current transformer with low power consumption and high response speed, the infrared switch has the advantage of low power consumption accordingly.
Description
Technical field:
The utility model relates to the domestic electric appliances energy-saving device, specifically is a kind of energy-conservation infrared switch.
Background technology:
At present, many household electrical appliance all are to carry out startup and shutdown by remote controller as television set, stereo set, DVD player, water dispenser etc., though this power on-off modes is convenient,, therefore the energy has been caused certain waste because still there is power consumption in they during standby.Thus, people more need little, the very energy-conservation power on-off modes of a kind of oneself power consumption to satisfy the power saving demand.
The utility model content:
The purpose of this utility model just is the deficiency at prior art, provides a kind of oneself power consumption very little energy-conservation infrared switch.
Realize that the technical scheme that the utility model purpose is adopted is: a kind of energy-conservation infrared switch is characterized in that: it comprises infrared radiation receiving circuit, single chip machine controlling circuit, output circuit, power circuit and current sampling circuit; Described power circuit is connected with infrared radiation receiving circuit, single chip machine controlling circuit, output circuit; Described single chip machine controlling circuit is connected with infrared radiation receiving circuit, output circuit and current sampling circuit; Described current sampling circuit comprises current transformer, resistance and electric capacity; The former limit winding of described current transformer is in parallel with output circuit, an end ground connection of its secondary winding, and the other end of secondary winding is connected with single chip machine controlling circuit; Described resistance and electric capacity are connected in parallel on the two ends of the secondary winding of current transformer simultaneously; The two ends of described electric capacity are connected with diode, and the negative pole of diode is connected with single chip machine controlling circuit.
The utlity model has following beneficial effect: because the power consumption of current transformer own is little, response speed is fast, and it is more accurate to detect current data, so the energy-conservation infrared switch of the utility model has also possessed, and oneself power consumption is little, response speed fast, it is accurate to detect current data, and advantage very easy to use.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structured flowchart of the present utility model.
Embodiment:
As shown in Figure 1, a kind of energy-conservation infrared switch, it comprises infrared radiation receiving circuit, single chip machine controlling circuit, output circuit, power circuit and current sampling circuit; Described power circuit is connected with infrared radiation receiving circuit, single chip machine controlling circuit, output circuit; Described single chip machine controlling circuit is connected with infrared radiation receiving circuit, output circuit and current sampling circuit; Described current sampling circuit comprises current transformer, resistance and electric capacity; The former limit winding of described current transformer is in parallel with output circuit, an end ground connection of its secondary winding, and the other end of secondary winding is connected with single chip machine controlling circuit; Described resistance and electric capacity are connected in parallel on the two ends of the secondary winding of current transformer simultaneously; The two ends of described electric capacity are connected with diode, and the negative pole of diode is connected with single chip machine controlling circuit.Because the power consumption of current transformer own is little, response speed is fast, and it is more accurate to detect current data, so the energy-conservation infrared switch of the utility model has also possessed above advantage.
