Description

Low standby energy consuming device

The present invention is an energy-saving device, especially a device capable of reducing standby energy consumption.

Most of the general electronic products must use DC power as the power supply. However, the power provided by the power company is mainly based on AC power. Therefore, when electronic products are needed, a rectifier is needed to rectify and convert AC power to DC power. For use in electronic products.

In addition, when the general electronic products use the mains as the power supply, the mains supply has a higher voltage value. Therefore, it is necessary to convert the alternating current into direct current, and further convert it to DC/DC to provide the applicable voltage value of the electronic product. .

When the user temporarily does not use the electronic product, the electronic product is in a standby state to wait for the user to use it next time. The electronic product in the standby state must also supply power to a standby unit, which consumes a small amount of power to provide a remote control for remote control by the remote controller when the user next time uses it.

However, when the general electronic product is in the standby state, the power of the standby unit is still supplied by the commercial power, and the commercial power must be converted by the AC/DC converter and the DC/DC converter to provide a suitable flow direction and a suitable voltage. To the standby unit, the standby unit waits for the user to remotely power on. When the AC-DC converter and the DC/DC converter convert the flow direction and voltage value of the mains, additional power conversion consumption is caused. Generally, the energy consumption of the electronic product in the standby state is about 50 milliwatts ( mW) to 1 watt (W). Therefore, even if the electronic product is in a standby state, there is excessive power consumption.

In view of the shortcomings of the prior art, the main object of the present invention is to provide a low standby energy consuming device to further reduce standby power consumption of electronic products.

In order to achieve the above object, the technical means adopted by the present invention is such that the low standby energy consuming device comprises: a rectifying and switching module connected to an alternating current power source for obtaining alternating current and converted into direct current, and having a power output end. a wireless module connected to the rectification and switching module, and outputting a control signal to the rectification and switching module according to a wirelessly received remote control signal to control whether the rectification and switching module is turned on to output the direct current; a rechargeable battery; and a battery charging unit connected to the power output end of the switch unit, the wireless module and the rechargeable battery, and when the power output is detected to output the direct current, the wireless power is supplied to the wireless module by the direct current And charging the rechargeable battery, and when the DC output is not output at the power output end, controlling the rechargeable battery to supply power to the wireless module.

The new type receives a remote control signal of a remote control device through the wireless module, and controls whether the switch unit is turned on according to the remote control signal, and outputs the direct current power from the power output end, and when the switch unit is turned on to output the direct current power, the power output is The terminal outputs the DC power to supply a load end power, so that the electronic product at the load end obtains electric energy and operates. When the switching unit is not turned on and the DC power is not output, the electronic product of the load end cannot be operated due to lack of power supply, so that the electronic product of the load end is completely shut down. When the switch unit is turned off, an open circuit is formed, so that the direct current output from the rectifying unit stops the current flow due to the disconnection of the switch unit, thereby avoiding the consumption of electric energy due to the conversion.

When the wireless module does not output the DC power at the output of the power source, the rechargeable battery provides power, and the power of the AC power source is not converted by the AC-DC converter or the DC/DC converter, thereby further reducing the extra consumption of the conversion. The electric energy also has the electric energy to operate normally, waiting for the user to control a remote control device to send the remote control signal.

The technical means adopted by the present invention for achieving the intended purpose are further explained below in conjunction with the drawings and the preferred embodiment of the present invention.

The low standby energy consuming device 10 of the present invention is configured to supply power to the wireless module 12 through the direct current when the power output 111 of the rectifier and switch module 11 outputs the direct current, and the direct current is not output when the power output 111 is not output. The wireless module 12 is powered by the rechargeable battery 14, so that the wireless module 12 can be powered and operated normally at any time to receive the remote control signal sent by the user using a remote control device 40 at any time. When the DC power is not output, the rectifier and switch module 11 forms an open circuit, so that the power provided by the AC power source 20 cannot be transmitted to the power output terminal 111 of the rectifier and switch module 11, and because of the rectification and switching mode Group 11 forms an open circuit to stop current flow and reduce the electrical energy consumed by the conversion.

The direct current. The magnitude of the wireless signal strength is inversely proportional to the distance between the remote control device 40 and the wireless module 12. The closer the distance between the remote control device 40 and the wireless module 12 is, the greater the wireless signal strength is. Conversely, the wireless signal strength is smaller. Therefore, when the distance between the remote control device 40 and the wireless module 12 is greater than a critical distance, the wireless signal strength is less than the threshold, so that the wireless module 12 controls the power of the rectifier and switch module 11. The output terminal 111 is not turned on and does not output the direct current. The remote control device 40 can set whether to control the wireless signal strength to control whether the rectification and switching module 11 is turned on or off.
