Wireless control power-off device

The present invention relates to a wireless control power-off device; in particular, to a wireless control power-off device, when the electrical connection is cut off, the electrical connection can be restored according to a wireless communication number.

With the development of electronic technology becoming more and more mature, all kinds of electrical appliances and people's lives are inseparable. All TVs, air conditioners, microwave ovens, etc. are common appliances in every household. The habit of the average user is to remain in standby mode when not using these appliances, or to still plug in, which still consumes power. Although each appliance consumes less power when not in use, for example, TV standby power consumption ranges from 6 to 15 watts, microwave oven standby power consumption ranges from 0.1 to 4.2 watts, and audio standby power consumption ranges from 0.04 to 14.9 watts. Not equal, but the power consumed by each appliance in the standby state is still considerable. It is estimated that each household may consume more than 300 degrees of electricity in one year, which not only wastes energy, but also increases electricity expenses, which is contrary to the current trend of energy conservation advocated.

Considering the above situation, some electrical appliances are equipped with a power-off device to cut off the connection between the electrical appliance and the power supply when the appliance is not in use. However, considering certain electrical appliances, in order to exert their functions or aesthetically pleasing, they will be placed at a lower or higher position, making it more inconvenient for the user to switch. For example, a television set that is placed against a wall and has a power-off device, if the power-off device switch is disposed behind the TV, the user must switch to the rear of the TV to switch when the user wants to switch the power-off device. The power-off device switch causes inconvenience in use.

In summary, there is a need for a power-off device that saves energy and is easy for the user to operate.

One of the aims of the present invention is to provide a wireless control power-off device for connecting one of the power terminals of a single appliance and a power source. The wireless control power-off device includes a specific power picker, a controller, a wireless control gate device, and a switch. The specific power extractor is configured to set a first reference voltage value, and the first reference voltage value corresponds to a power threshold. The controller is configured to compare the first reference voltage value and a second reference voltage value, and when the second reference voltage value is less than the first reference voltage value, the controller generates a shutdown signal. The wireless control gate device is configured to receive the wireless control signal and generate a pilot communication number. The switch is used to cut off the electrical connection between the power terminal and the power source according to the off signal, and when the electrical connection is cut off, the electrical connection between the power terminal and the power source is restored according to the communication number.

With the above arrangement, the creation can not only reduce the energy loss during the standby of the electric appliance, but also improve the convenience of the user in the use of the device due to the design of the wireless remote control. After referring to the drawings and the embodiments described later, the technical field has the usual knowledge to explain the other purposes of the creation, and the technical means of the creation in a timely manner.

In the following, the description of the present invention relates to an embodiment of a wirelessly controlled power-off device that is more power efficient. However, the embodiments of the present invention are not limited to specific environments, applications, or implementations, and thus, the description of the embodiments is for illustrative purposes only and is not a limitation of the present invention.

The first embodiment of the wireless control power-off device of the present invention is shown in Fig. 1. The wireless control power-off device 1 includes an input terminal 101, an output terminal 103, a fuse 105, a bridge full-wave rectifier 107, a Zener diode 109, a filter capacitor 111, a transformer 115, and a specific The power extractor 117, a transistor 121, a switch 123, a controller 142, and a wireless control gate device 144. The input terminal 101 and the output terminal 103 are used to connect one of the power terminals of a single appliance and a power source (not shown). The connection relationship of all components is shown in Figure 1.

Wherein, the power end connected to the wireless control power-off device 1 is connected to a control circuit inside the electric appliance, thereby enabling the electric appliance to be activated. Therefore, the electrical system obtains an external power source through the wireless control power-off device 1, for example, an AC power source of 110 volts is activated. In other embodiments, the wireless control power-off device 1 can also be installed inside the appliance.

The operation of the wireless control power-off device 1 will be described below by taking an AC power source as an example. After the plug of the electric appliance is connected to the socket, the wireless control power-off device 1 obtains an AC power of 110 volts. When the AC power is input from the input terminal 101, it will pass through the fuse 105 first to avoid excessive current and achieve the effect of protecting the circuit.

When the wireless control power-off device 1 is in a non-conducting state, and the user wants to activate the electrical device, a remote control method, such as a remote controller, can be used to send an infrared wireless control signal 145, and the wireless control gate device 144 is configured to receive The signal 145 is wirelessly controlled and a pilot number 146 is generated to activate the wireless control power down device 1. After it is turned on, the AC power is supplied from the output terminal 103 to the appliance at the same time.

Please refer to FIG. 2, which illustrates a specific embodiment of a wireless control gate device 144. The wireless control gate device 144 includes a wireless receiving module 147 and a conductive module 148. The diode 154 and the resistor 155 are connected in parallel to the wireless receiving module 147 and the conductive module 148, and are mainly used to form a guiding path. When the wireless receiving module 147 generates a voltage signal, It is transmitted to the conduction module 148 via the resistor 155. Capacitor 156 is suitable as a filter capacitor. A Zener diode 158 and a capacitor 159 are connected in parallel to provide a stable voltage. The resistor 160 is connected to the conduction module 148 and the Zener diode 158 and the capacitor 159.

The wireless receiving module 147 is configured to receive the wireless control signal 145, and the conductive module 148 is coupled to the wireless receiving module 147 for generating the communication number 146 according to the wireless control signal 145. FIG. 2 further illustrates a detailed embodiment of the wireless receiving module 147 and the conductive module 148. In this embodiment, the wireless receiving module 147 is an infrared receiving module having three pins 147a, 147b, and 147c connected to one end of the resistor 155, the conducting module 148, and one end of the Zener diode 158. . The pass module 148 includes a power MOSFET half-effect transistor (MOSFET) 150 and a bi-carrier junction transistor 151. The power MOSFET half-effect transistor 150 is adapted to be turned on according to the wireless control signal 145 to generate the communication number 146. The dual-contact junction transistor 151 has a base, a collector, and an emitter coupled to a gate of the power MOS half-effect transistor 150 in the wireless receiving module 147. The emitter and the base are coupled to the wireless receiving module 147. The wireless receiving module 147 turns off the dual carrier junction transistor 151 in response to the wireless control signal 145 to turn on the power MOS half-effect transistor 150 to generate the pilot number 146. The on-resistance 157 is used to provide a path for the power MOS half-effect transistor 150 to be turned on when the bipolar junction transistor 151 is not conducted.

When the wireless receiving module 147 has not received the signal, the status of each pin is as follows: the pin 147a assumes a high potential (HIGH), the pin 147b is grounded, and the pin 147c presents a fixed voltage, which in this embodiment can be It is 5V. At this time, due to the potential difference between the pins 147a and 147b, the base/emitter junction of the bipolar junction transistor 151 is affected by the potential difference, and the conduction state is exhibited, so that the power MOS half-effect transistor 150 is not present. On state. When the wireless receiving module 147 receives the wireless control signal 145, the state of the pin 147a changes from a high potential (HIGH) to a low potential (LOW), thereby turning off the dual carrier junction transistor 151 to turn on the power gold oxide. The half field effect transistor 150 is thus used to generate the pilot number 146 to activate the appliance.

After the appliance is powered, since the wireless receiving module 147 no longer receives the wireless control signal 145, the pin 147a will change from a low potential (LOW) to a high potential (HIGH), at which time the dual-carrier junction transistor 151 is again turned on to turn off the power MOSFET half-current transistor 150, and the power required by the appliance is continuously powered via switch 123. When the appliance is turned off, only the wireless receiving module 147 consumes power, which can greatly reduce standby power consumption.

In this embodiment, the wireless control power-off device further includes a battery module 153 for providing a battery power to the wireless control gate device 144. In another embodiment, the power can be directly supplied from the AC power source to the wireless control device. The gate device 144, which is well known to those skilled in the art, can readily understand how to provide AC power to the wireless control gate device 144, and details are not described herein.

Referring to FIG. 1 again, when the wireless control signal 145 turns on the wireless control gate device 144, the AC power source will simultaneously supply power from the output terminal 103 to the appliance and the bridge full-wave rectifier 107. In this embodiment, the bridge full-wave rectifier 107 includes a first input terminal 135, a second input terminal 137, a ground terminal 139, and an output terminal 141. The bridge full-wave rectifier 107 receives 110 volt AC power through the first input terminal 135 and the second input terminal 137, and after outputting the internal diode, the output terminal 141 of the bridge full-wave rectifier 107 outputs 12 volt DC power. 102, the bridge full-wave rectifier 107 rectifies the 110 volt AC power supply and outputs a 12 volt DC power 102.

The Zener diode 109 is used to stabilize the voltage of the 12 volt DC 102 output from the bridge full wave rectifier 107. After filtering by the filter capacitor 111, the DC power 102 is not only input to the power terminal 129 of the timer 113 in the controller 142 for supplying power to the timer 113, but also the power terminal of the comparator 142 of the input controller 142 is used as the power source of the comparator 119. And input to the specific power extractor 117 and the emitter of the transistor 121, wherein the transistor 121 is a PNP bipolar junction transistor.

The specific power extractor 117 of the embodiment is a variable resistor for setting a first reference voltage value 104, wherein the first reference voltage value 104 corresponds to an adjustable preset power valve. Value, the power threshold is between 5-10 watts. The controller 142 is configured to compare the first reference voltage value 104 and a second reference voltage value 106. When the second reference voltage value 106 is less than the first reference voltage value 104, the controller 142 generates a shutdown signal. 143.

In this embodiment, the controller 142 includes a comparator 119. The transformer 115 transfers the output power of one of the electrical appliances to the other end, and converts the voltage of the electrical appliance into a voltage acceptable to the comparator 119. The voltage is used as one of the operational amplifiers as the second reference voltage value 106.

The comparator 119 is configured to compare the first reference voltage value 104 and the second reference voltage value 106. When the second reference voltage value 106 of one of the comparators 119 is less than the first reference voltage value 104, a comparison signal 152 is generated. In particular, comparator 119 can be an operational amplifier.

As described above, when the second reference voltage value 106 is smaller than the first reference voltage value 104, the timer 113 calculates whether a time exceeds the power-off time. If the time exceeds the power-off time, the controller 142 generates a shutdown signal 143 according to the comparison signal 152, and the switch 123 cuts the electrical connection between the power terminal and the power source according to the shutdown signal 143, and cuts off the When electrically connected, the electrical connection between the power terminal and the power source is restored according to the communication number 146. The aforementioned power down time is an adjustable time, for example 10 minutes. The timer 113 can be a mechanical timer or an electronic timer. The aforementioned switch 123 can be one of a relay and a silicon controlled rectifier.

In detail, when the user turns off the appliance, the AC power is first output from the output terminal 103 and transmitted to the bridge full-wave rectifier 107. The bridge full-wave rectifier 107 also rectifies the 110 volt AC power source into a DC power 102, which is then regulated by the Zener diode 109 and sent to the timer 113, the specific power extractor 117, the comparator 119, and the transistor 121. Shooting pole.

When the comparator 119 compares the second reference voltage value 106 and the first reference voltage value 104, since the electrical device assumes the standby state, the second reference voltage value 106 is smaller than the first reference voltage value 104, and the comparator 119 outputs a low level. The comparison signal 152 of the bit is reset to the reset terminal 131 of the timer 113, and the timer 113 starts counting after receiving the comparison signal 152 of the low level.

When the timing of the timer 113 exceeds the preset power-off time of the timer 113, for example, more than 10 minutes, the output terminal 133 of the timer 113 outputs a high-level signal to the base of the transistor 121, and thus the transistor 121 When the current is off, the current cannot flow through the collector of the transistor 121 to the switch 123. Therefore, the switch 123 is no longer turned on, so that the AC power can no longer be supplied to the appliance, thereby blocking the power consumption of the appliance during standby and turning off the appliance.

At this time, after the electric appliance is turned off, only the wireless control gate device 144 is in the standby state and continuously consumes the power, so that the power consumption of the electric appliance standby can be significantly improved.

In the foregoing embodiment, assuming that the standby power of the appliance is 3 watts and the power used by the appliance is 7 watts, the first reference voltage value 104 can be appropriately adjusted so that the corresponding power threshold is 5 watts. The comparator 119 is configured to compare the two reference voltage values. Since the electrical appliance is being used, that is, the electrical power used is greater than the power threshold, the second reference voltage value 106 is greater than the first reference voltage value 104, and the comparator 119 outputs a high value. The comparison signal 152 of the level is reset to the reset terminal 131 of the timer 113. After receiving the comparison signal 152 of the high level, the timer 113 continuously resets the timing of the timer 113.

Since the timer 113 is continuously reset, the timing time is not greater than a predetermined power-off time in the timer 113. For example, 10 minutes, the output terminal 133 of the timer 113 outputs a low-level signal to the transistor 121. At the base, at this time, the transistor 121 is turned on, and the current 110 flows out through the collector of the transistor 121 to the switch 123 to be turned on, so that the wireless control power-off device and the internal path can be maintained.

When the electrical appliance is continuously used, the second reference voltage value 106 continues to be greater than the first reference voltage value 104, and the comparator 119 continuously outputs the high-level comparison signal 152. Therefore, the timer 113 is continuously reset, and the timing time is not It is larger than the power-off time in the timer 113, so the electric appliance can continuously obtain the power.

The second embodiment of the present creation is shown in Fig. 3. In this embodiment, a wireless control power-off device 2 such as the wireless control power-off device 1 is disposed in a junction box 23 of one of the sockets 21 for providing an AC power source 20, and the socket 21 is combined with a panel 27, It is embedded in a wall, that is, the AC power supply 20 provided by the power company is first connected to the socket 21 via the wireless control power-off device 2. When the appliance is to be used, it is only necessary to insert the plug of the appliance into the socket 21 of the embodiment, so that the appliance using the socket 21 can save energy by wirelessly controlling the power-off device 2. The wireless control power-off device 2 of the present embodiment includes a wireless control gate device 29, and the wireless control power-off device 2 can be controlled by a remote control device, such as the aforementioned remote controller, to facilitate the user to use the wireless control power-off device 2.
