Description

Apparatus for Reducig Waiting time of Boiler}

The present invention relates to an apparatus for reducing standby power of an instantaneous gas boiler for home use, in particular, in an instantaneous gas boiler for home use, to reduce standby power consumption of a control device generated during unburned standby time without heating or hot water. Relates to a device.

Electric devices whose operation is controlled using a remote control such as television or audio, or electric devices that have a predetermined pre-power consumption operation before the original operation, such as an operation standby lamp, have a standby mode. Even when the electric device having such a standby mode is powered off, power consumption occurs when the power plug is connected to an external power source. In general, the power consumed by standby power per individual electrical equipment is 1W ~ 25W is small. However, the sum of the energy wasted by the standby power of these devices is enormous. In addition, the production of 1KW of electricity usually generates about 4kg of carbon dioxide, so if the standby power is left unattended, global warming may be further increased. Therefore, it is necessary to prevent energy waste by standby power not only for saving energy but also for preserving the global environment.

In addition, the control device of the gas boiler is usually connected to a constant power supply and immediately reacts to a change in temperature or use of hot water, and aims to reach a desired set temperature of heating or hot water temperature within an extremely short time. Consumption of power will be consumed in the accessories of the sensors and control devices.

The simplest and easiest way to avoid wasting power from standby power is to disconnect the power supply by disconnecting the power plug each time the appliance is turned off. However, this is very cumbersome, so users know that standby power is being consumed, while leaving electrical devices unplugged. Therefore, technologies for reducing power waste due to standby power while power plugs are connected to electric devices are being developed. It is commonly used to attach a switch to a power strip or outlet device. The switch is attached to a multi-tap or outlet device. When the user is finished using the electric device, the switch is turned off to completely cut off the connection to the external power supply. To connect to a power source.

Alternatively, by using a human body sensor or a proximity sensor, when the user moves away from the electronic device, the connection between the external power source and the electric device is automatically cut off, and when the user is close to the electric device, the external power source and the electric device are connected again. There is technology.

The method of attaching a switch to the multi-tap or outlet device may be more convenient than unplugging the power plug, but it is still inconvenient to switch on / off the switch every time the user turns off and on the electric device. There is a ham.

In addition, the method of detecting the user's approach has a problem that the user has to consciously approach the electrical device in order to use the electrical device. Furthermore, there is a possibility of malfunction depending on the sensitivity of the sensor.

The present invention constructs a switching power circuit to reduce power consumption during unburned standby time, and divides the circuit of the power supply of the control device accessory into a pulsating accessory and an electric interruption accessory in standby to perform efficient control according to processing conditions. By using this method, the standby power consumption is reduced by 1/3 compared to the conventional method (usually from 3W to 1W), which reduces the power bill, generates heat, and reduces the power consumption of boilers with a short actual operating time and long standby time. It is an object of the present invention to provide a device for reducing the standby power of a boiler that can improve environmental friendliness.
