Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in order to simplify the drawings, some conventional structures and components will be shown in the drawings in a simple and schematic manner, and repeated components will be represented by the same numbers.

Referring to FIG. 1, a first embodiment of a wireless remote control electrical appliance according to the present invention is adapted to be detachably electrically connected to a power unit 300 and is controlled by a wireless control signal output by a wireless signal transmitting device 400. The power unit 300 includes an external switch 310, a first power source 320 electrically connected to the external switch 310, and a second power source 330.

In this embodiment, the power unit 300 is a general single-phase three-wire household power source, and its wires are pulled out according to the voltage of the power supply to correspond to the first power source 320 and the second power source 330. For example, if the power supply voltage of the power unit 300 is 110 volts, the first power supply 320 is a live wire, and the second power supply 330 is a neutral line (ground); if the power supply voltage of the power unit 300 is 220 volts Then, the first power source 320 and the second power source 330 are both live wires. In this way, an electric power can be obtained by being electrically connected to the first power source 320 and the second power source 330. However, the power unit 300 is not limited to this, and a three-phase three-wire or three-phase four-wire industrial power source can also be used. In addition, the external switch 310 is a single-cut switch commonly installed on a wall in a home for turning on electrical appliances.

The wireless remote control appliance includes an electrical load 100 electrically connected to the second power supply 330 and a wireless remote control switch device 200.

In this embodiment, the electrical load 100 is an electric lamp, but it is not limited thereto, and can also be an electric fan or other types of electrical appliances. It should be noted that before the wireless remote control switch device 200 is installed, the electrical load 100 is electrically connected to the external switch 310 away from one end of the first power source 320 and the second power source 330 and passes through the external switch 310 , The appliance load 100 is turned on or off. When the wireless remote control switch device 200 is to be installed, only the pins of the electrical load 100 that are originally electrically connected to the first power source 320 are connected to the wireless remote control switch device 200.

The wireless remote control switch device 200 includes a port unit 210, a switch unit 220, a wireless module 230, a control unit 240, and a power module 250.

The port unit 210 has a first port 211, a second port 212, and a third port 213. The first port 211 is electrically connected to the external switch 310, and is electrically connected to the first power source 320 through the external switch 310. The second port 212 is directly and electrically connected to the first power source 320. The third port 213 is electrically connected to the electrical load 100, and is electrically connected to the second power supply 330 through the electrical load 100. The first power source 320 forms a first path through the first port 211 to the third port 213, and the first power source 320 forms a second path through the second port 212 to the third port 213.

The switch unit 220 includes a first switch module 260 and a second switch module 270. In this embodiment, the first switch module 260 and the second switch module 270 are both electromagnetic relays (Relay), but are not limited thereto, and may also be solid state relays (SSR). Or a transistor. Moreover, the first switch module 260 includes a first terminal 261, a second terminal 262, a third terminal 263, and a driver 264; the second switch module 270 includes a first terminal 271, a second terminal The terminal 272, a third terminal 273, and a driver 274. In addition, the contact symbols in the diagram correspond to the contact names commonly used in general electromagnetic relays, such as common contact COM, normally open contact NO (Normal Open), and normally closed contact NC (Normal Close).

Therefore, in this embodiment, the first terminal 261 is used as a normally open contact NO and is electrically connected to the second port 212, and the second terminal 262 is used as a common contact COM and electrically connected to the third terminal 273. The third end 263 is a normally closed contact NC but is empty. The first end 271 is a normally closed contact NC and is electrically connected to the first port 211. The second end 272 is a common contact COM and electrically connected. The third port 213. In addition, the driver 264 and the driver 274 are respectively controlled by the control unit 240 to switch between an excited state and a non-excited state.

The wireless module 230 is adapted to receive the wireless control signal and output a wireless switch signal related to the wireless control signal. It should be noted that the wireless signal transmitting device 400 in this embodiment is a device capable of outputting the wireless control signal through an application program and a wireless signal transmitting module (not shown), such as a smart phone, a tablet However, it is not limited to this, and it can also be a wireless signal transmitting module that only has a function of outputting the wireless control signal. In addition, the wireless control signal may be a radio frequency signal, a Bluetooth signal, or an infrared signal. In addition, the wireless control signal includes a message of a remote control switching state, which serves as a basis for the control unit 240 to switch and control the switch unit 220.

The control unit 240 has a detection module 241 and a signal processing module 242 that connects the wireless module 230 and the detection module 241. The detection module 241 is used to detect an electrical signal, such as a voltage or a current, of the external switch 310 opposite to one end of the first power source 320 to output a sensing signal to the processing module 242. Therefore, the sensing signal is a manual switching state related to the external switch 310. The processing module 242 receives the wireless switching signal and the sensing signal, and can control the driver 264 and the driver 274 to change the first path and the driver when any one of the remote control switching state and the manual switching state changes. One of the second paths is on or off.

The power module 250 is electrically connected between the first power source 320 and the second power source 330 and outputs a converted power related to the power to the wireless module 230 and the control unit 240. In this embodiment, the power module 250 is used as an AC-DC converter to provide the DC power required by the wireless module 230 and the control unit 240, but if the wireless module 230 and the control unit 240 can be used directly The alternating current does not need to be converted through the power module 250.

Therefore, please refer to FIG. 7 for cooperation. Among them, (a) and (b) are two timing diagrams showing different initial states, respectively. (A) An open state is generated between the first power source 320 and the second power source 330 (low standard). (B) Start; (b) Start from a short-circuit state (high level) between the first power source 320 and the second power source 330. One of the implementation modes can be selected according to the needs of the user. And, as long as any one of the remote switching state and the manual switching state changes, the processing module 242 controls the driver 264 and the driver 274, so that the state between the first power source 320 and the second power source 330 is changed by The disconnected state becomes the short-circuited state, or the short-circuited state becomes the open-circuited state.

Take (a) as an example to further explain. Initially, when the external switch 310 is turned on and the sensing signal is at a low level, and the wireless control signal is also at a low level, the driver 264 is controlled by the control unit 240 to be in the excited state, so that the The second terminal 262 is connected to the first terminal 261; the driver 274 is in the non-excitation state under the control of the control unit 240, so that the second terminal 272 is connected to the first terminal 271. At this time, neither the first path nor the second path is conductive, and the first power source 320 and the second power source 330 are in the disconnected state, so that the electrical load 100 is not operated (low level).

Then, if the wireless control signal is switched to a high level, the processing module 242 detects that the remote control switching state is changed, and controls the driver 274 to be in the excited state, so that the second terminal 272 is connected to the third terminal 273. At this time, since the second terminal 262 is connected to the first terminal 261, the second path is conducted, and the first power source 320 and the second power source 330 are in the short-circuit state, so that the electrical load 100 operates (high level) ). On the other hand, if the external switch 310 is turned off and the sensing signal is switched to a high level, the processing module 242 detects that the manual switching state changes, and controls the driver 264 to be in the non-excitation state, so that the second The terminal 262 is connected to the third terminal 263. At this time, since the second terminal 272 is connected to the first terminal 271, the first path is conducted, and the first power source 320 and the second power source 330 are also in the short circuit state, which can also make the electrical load 100 operate.

Similarly, as long as any one of the remote switching state and the manual switching state changes, the processing module 242 controls the driver 264 and the driver 274, so that neither the first path nor the second path When it is turned on, the first power source 320 and the second power source 330 are in the disconnected state, so that the electrical load 100 is not operated. In addition, for the embodiment shown in (b), it can be seen that the difference in the initial state will only affect the control of the second switch module 270 by the processing module 242.

In this way, when any one of the remote switching state and the manual switching state changes, the first power source 320 and the second power source 330 can be switched between the short-circuit state and the open-circuit state, so that the The electrical load 100 adds a function of wireless switch control.

It is worth mentioning that the above situations are the results of the implementation of the control unit 240 in a normal mode, but if the control unit 240 is in an abnormal mode, a failure occurs and the driver 264 and the driver 274 can no longer be used. Take control. At this time, both the driver 264 and the driver 274 are in the non-excitation state, so that the second terminal 262 is connected to the third terminal 263, the second terminal 272 is connected to the first terminal 271, and the second path is always non-conductive, and Whether the first path is turned on or not can be switched through the external switch 310, so the user can still switch control the electrical load 100 through the external switch 310.

In addition, the connection relationships between the contacts of the first switch module 260 can be adjusted correspondingly to the implementation of the first embodiment to form a second embodiment of the wireless remote control electrical appliance of the present invention. (See Figure 2), a third embodiment (see Figure 3), and a fourth embodiment (see Figure 4).

Therefore, as shown in FIG. 2, the difference between the second embodiment and the first embodiment is only that the first end 261 in the second embodiment is used as a common contact COM, and the second end 262 is used as a normally open Contact NO. In addition, the timing diagrams of the first embodiment and the second embodiment are shown in FIG. 7.

As shown in FIG. 3, the third embodiment differs from the first embodiment only in that the first end 261 in the third embodiment is used as a common contact COM, and the second end 262 is used as a normally closed contact. NC, and its third end 263 is a normally open contact NO.

As shown in FIG. 4, the fourth embodiment differs from the first embodiment only in that the first end 261 in the fourth embodiment is used as a normally closed contact NC, and the third end 263 is used as a normally open contact. Click NO. In addition, timing charts of the third embodiment and the fourth embodiment are shown in FIG. 8.

Similarly, the connection relationship between the port unit 210 and the power unit 300 can also be adjusted correspondingly to the implementation of the first embodiment to form a fifth embodiment of the wireless remote control electrical appliance of the present invention ( See Figure 5) and a sixth embodiment (see Figure 6).

Therefore, as shown in FIGS. 5 and 6, the first port 211 in the fifth embodiment and the sixth embodiment is directly electrically connected to the first power source 320, and the second port 212 is electrically connected to the external The switch 310 is electrically connected to the first power source 320 through the external switch 310. In addition, the first port 211 is electrically connected to the first end 271 as a normally open contact NO, the second port 212 is electrically connected to the first end 261, and the third port 213 is electrically connected to a common contact COM The second end 272.

In addition, the fifth embodiment differs from the sixth embodiment only in that the first end 261 in the fifth embodiment is a normally closed contact NC, and the second end 262 is a common contact COM and is electrically connected. The third end 273. In the sixth embodiment, the first terminal 261 serves as a common contact COM, and the second terminal 262 serves as a normally closed contact NC and is electrically connected to the third terminal 273. In addition, timing charts of the fifth embodiment and the sixth embodiment are shown in FIG. 9.

It should be noted that according to FIG. 9, when the control unit 240 of the fifth embodiment and the sixth embodiment is in the normal mode, the driver 264 is constantly controlled by the control unit 240 to be in the excited state, so that the first One end 261 is not electrically connected to the second end 262, so that the second path is always non-conductive. When any one of the remote control switching state and the manual switching state changes, the driver 274 is controlled by the control unit 240 to switch between the excited state and the non-excited state, and the second terminal 272 is switched to the first terminal. One of 271 and the third terminal 273, thereby driving the first power source 320 and the second power source 330 to switch between the short-circuit state and the open-circuit state.

If the control unit 240 is in the abnormal mode, at this time, the driver 264 and the driver 274 are in the non-excitation state, and the first terminal 261 is not electrically connected to the second terminal 262, so that the first path is always non-conductive. The second terminal 272 is connected to the third terminal 273, so that the conduction of the second path can still be switched through the external switch 310, so the user can still switch control the electrical load 100 through the external switch 310. .

Through the above description, it can be understood that the main contribution of the wireless remote control switch device 200 of the present invention is to design the settings of the switch unit 220 and the control adjustment of the processing module 242 to allow the electrical appliances connected to the wireless remote control switch device 200 The load 100 can switch the first power source 320 and the second power source 330 between the short-circuit state and the open-circuit state when any one of the remote switching state and the manual switching state changes, thereby allowing the electrical appliance to load. 100 Added wireless switch control function. In addition, when the wireless remote control switch device 200 fails, the user can still control the electrical load 100 through the external switch 310, effectively improving the robustness of the overall system.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, that is, any simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the patent specification of the present invention are still It is within the scope of the invention patent.
