[0021] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0022] Reference below Figures 1 to 5 A dual-control interconnected range hood and stove control system according to an embodiment of the present invention is described, including a range hood 1 and a stove 2. The range hood 1 is provided with a range hood power board 102, and the stove 2 is provided with a stove power board 202. A gesture sensing switch 101 is provided on the front surface of the range hood 1, and the gesture sensing switch 101 is connected to the range hood power board 102. The front surface of the stove 2 is provided with a stove knob control switch 201, and the stove knob control switch 201 is connected to the stove power board 202. The gesture sensing switch 101 corresponds to the stove knob control switch 201 and the gesture sensing switch 101 detects the usage status of the stove knob control switch. The range hood power board 102 is also provided with a range hood main controller MCU and a range hood Bluetooth module. The stove power board 202 is also provided with a stove main controller MCU and a stove Bluetooth module. The range hood main controller MCU and the range hood Bluetooth module are connected, the stove main controller MCU and the stove Bluetooth module are connected, and the range hood Bluetooth module and the stove Bluetooth module communicate with each other.

[0023] This structure uses the gesture sensing switch 101 to correspond to the stove knob control switch 201, and the gesture sensing switch 101 detects the usage status of the stove knob control switch. It cooperates with the range hood Bluetooth module and the stove Bluetooth module to communicate, providing a dual-control interconnection control solution, effectively solving the problem of damage to one of the control switches or Bluetooth modules, and can also be operated normally, meeting users' demand for intelligent and diversified control experience.

[0024] The stove controller MCU in this circuit is connected to a pulse igniter. When the stove knob control switch 201 is activated, it outputs an operating signal to the stove controller MCU, which activates the pulse igniter. The burner on stove 2 then discharges gas and ignites. Furthermore, when dual-control is interconnected, the range hood controller MCU also controls corresponding components (e.g., the pulse igniter). The range hood power board 102 is also connected to a push rod motor M1 and a range hood motor M2. These motors are also activated. Push rod motor M1 pushes a push rod, which in turn swings the panel, opening it. Simultaneously, range hood motor M2 drives a worm gear to rotate, absorbing exhaust, harmful gases, or fumes generated by stove 2.

[0025] The range hood power board 102 described in this circuit features a low-voltage control circuit, which is connected to the range hood's Bluetooth module and the range hood's main controller (MCU). This circuit primarily provides power to the Bluetooth module and the MCU, and typically includes components such as a circuit breaker, contactor, and thermal relay.

[0026] The range hood power supply board 102 described in this circuit is provided with a high-voltage isolation control circuit, a main power supply circuit, an auxiliary power supply circuit and a DC motor control circuit. The high-voltage isolation control circuit and the auxiliary power supply circuit are respectively connected to the range hood main controller MCU, the main power supply circuit is respectively connected to the high-voltage isolation control circuit, the auxiliary power supply circuit and the DC motor control circuit, the auxiliary power supply circuit is connected to the DC motor control circuit, and the range hood main controller MCU and the DC motor control circuit are connected via the UART isolation communication protocol.

[0027] High-voltage isolation control circuits are primarily used to ensure the safety of high-voltage electrical equipment and devices during maintenance work, isolating voltages. They cannot be used to cut off or apply load current or interrupt short-circuit currents, and are only suitable for certain switching operations that do not generate strong arcs.

[0028] The main power circuit is the circuit directly responsible for exchanging or controlling electrical energy in electrical equipment or power systems. It serves as the path for power current to flow and includes all power components, including switching devices, energy storage devices, pulse transformers, filters, output rectifiers, and the power input and load terminals.

[0029] The range hood controller MCU and the gesture sensing switch 101 described in this circuit are connected via the UART communication protocol. The UART communication protocol converts parallel input signals into serial output signals, thus realizing asynchronous data transmission.

[0030] The stove power board 202 in this circuit is equipped with a low-voltage control circuit, which is connected to the stove's main controller (MCU). This circuit primarily provides power to the MCU and typically includes components such as a circuit breaker, contactor, and thermal relay.

[0031] Through the above circuit, dual-control interconnection is achieved, the range hood 1 and the stove 2 can be operated synchronously, and can also be used independently. This solution brings users a better intelligent and diversified control experience and needs.

[0032] The working principle of this circuit is as follows: Range hood 1 and stove 2 are powered simultaneously, starting the range hood Bluetooth module and the stove Bluetooth module to enter Bluetooth pairing mode, waiting for pairing to succeed before entering standby mode. Meanwhile, gesture sensor switch 101 and stove knob control switch 201 also enter standby mode. When the gesture sensor switch 101 is manipulated to perform operations such as gear adjustment, lighting on / off, and time delay, the control status of the gesture sensor switch 101 is input to the range hood main controller MCU, which then controls the speed of the range hood motor M2 or lighting equipment (such as LED lamps, which are electrically connected to the range hood main controller MCU).

[0033] When the gesture sensor switch 101 and the stove knob control switch 201 are connected, and the stove knob control switch 201 and gesture sensor switch 101 are in standby mode and inactive for three minutes, the stove will be turned off. Furthermore, when the stove knob control switch 201 is in the active-off state, the stove knob control switch 201 is also activated, instructing the range hood controller MCU to control the speed of the range hood motor M2. The gesture sensor switch 101 operates by sensing the heat radiation from the human body. When a person approaches, the gesture sensor switch senses the heat released by the hand and converts this heat signal into an electrical signal. The gesture sensor switch detects the hand's movement of the stove knob control switch 201, thereby turning the range hood 1 on (e.g., starting the speed of the range hood motor M2).

[0034] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
