[0060] Figure 5 illustrates the circuit diagram of power surge protection circuit in the smart kitchen hood 100 in accordance with an embodiment of the invention. The smart kitchen hood chimney 100 may be provided with a power surge protection circuit for protecting the electrical circuit of the chimney during sudden power surge condition. The power surge protection circuit may be provided with a Metal Oxide Varistor (MOV), a fuse, inductors, capacitors and a thermal disconnect to protect the electronic devices and the electrical component from voltage surges or transients. In an embodiment of the present invention, the fuse may be a 1A fuse (F1), inductor may be a 2mH drum coil inductor (L1, L2), MOV may be a 10D471k Varistor (R1) and capacitor may be C1 as shown in Figure 5.
[0061] The MOV acts as a barrier against the current flow. The MOV regulates the current flow through the various electronic devices that may be connected to the power surge protection circuit. The MOV may be designed as a nonlinear voltage-current characteristic such that when the voltage exceeds the certain limit or threshold limit known as clamping voltage, the MOV conduct significantly and provides low impedance path for the surge current. Further, the MOV circuit may have a finite lifespan and degraded over time due to the repetitive voltage surge cycles. Thus, the power surge protection circuit may be periodically inspected and may be replaced to maintain their effectiveness.
[0062] In an embodiment of the present invention, during normal operation of the chimney, the MOV in the power surge protection circuit acts as an open circuit, allowing the regular voltage pass through to the connected devices. During the voltage surge conditions, the MOV provides the low impedance circuit to the surge current to minimize the effect of the surge current by absorbing the energy of the voltage surge and limits the voltage across the connected devices to a safe level. Further, the other components of the surge protect circuit such as fuse and thermal disconnect ensures that excess energy may be safely dissipated and protects the MOV from overheating or failure. Once the surge voltage subsidized or completely dissipated, the MOV returns to its high impedance state and regulates the normal operation of the connected devices.
[0063] Figure 6 illustrates the circuit diagram of the relay drive circuit in the smart kitchen hood chimney in accordance with an embodiment of the invention. In an embodiment of the present invention, the smart kitchen hood chimney 100 may be provided with a relay drive circuit for driving the relays to control the power. The relay drive circuit may be coupled to a ULN 2003A inverter IC used to drive relays. The IC may be configured to perform the high side switching with respect to input signal on the input pins. The ULN2003 may be used as a relay driver circuit to control relays using a low-power control signal from a microcontroller or the other digital control circuitry. Further, the ULN2003 provides high-current drive capability for the relay coil and ensures isolation between the control circuit and the relay. In an embodiment of the present invention, the smart kitchen hood chimney may use a 10 A relay to drive loads and ESP module as main microcontroller.
[0064] The steps for operating the ULN2003-based relay drive circuit may involve a step of the relay connection. The relay coil may be connected between the positive power supply such as +5V or +12V and one of the output pins from the plurality of the output pins ranges from IN1-IN7 of the ULN2003 and the other end of the relay coil may be connected to the ground (GND). The next step to provide input signal to the relay drive circuit by connecting the control signal from the microcontroller or digital control circuitry to one of the input pins IN1-IN07 of the ULN2003. In an embodiment of the present invention, the control input signal should be a low-level logic signal of around 5V to trigger the relay operation.
[0065] In the next step, connecting each input pin of the ULN2003 to a Darlington transistor pair. When the control signal is applied to the ULN2003. The Darlington pair turned ON. The Darlington transistor pair provides a high-current gain, allowing a large amount large amount of current to flow through the relay coil and enables the ULN2003 to drive the relay, even if the control signal itself cannot provide sufficient current.
[0066] The ULN2003 provides electrical isolation between the control circuitry and the relay to protect the control circuit from any voltage spikes or back-EMF generated by the relay coil during switching. Further, the ULN2003 also includes built-in clamp diodes to protect the transistors from inductive load kickback. The ULN2003 has inverted logic. When a logic high signal is applied to the input pin, the corresponding output pin is pulled to ground (low level), activating the relay. Conversely, when a logic low signal is applied, the output pin is floating (high impedance), deactivating the relay. The ULN2003 in a relay drive circuit controls the connected relays using a low-power control signal and drive higher current loads without overloading the control circuitry.
