[0001] This invention relates to the field of household appliance technology, specifically to a range hood and stove assembly. Background Technology

[0002] With the rapid development of society, people have higher and higher requirements for their home life, especially in terms of healthy eating. High-quality ingredients and good cooking skills can bring people a feast for the eyes and ears. A clean and comfortable kitchen environment can bring people physical and mental health and the pleasure of making delicious food. Gas stoves and range hoods play an important role in the kitchen.

[0003] The range hood and cooktop assembly includes a range hood and a gas cooktop. In actual use, the range hood is generally powered by electricity, while the gas cooktop is powered by gas. In the event of a power outage in the area, the range hood and cooktop assembly can only function as a cooktop and cannot perform the function of removing cooking fumes, thus failing to ensure a clean and fresh kitchen environment and reducing the user experience. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect of existing range hood and stove components that cannot guarantee a clean and fresh kitchen environment during power outages, thereby providing a range hood and stove component that can be used during power outages.

[0005] To address the aforementioned problems, this invention provides a range hood and stove assembly, comprising: a stove cabinet with a stove, a stove ignition switch, and a gas ignition switch mounted on it; a range hood positioned above the stove cabinet, comprising a housing with an air inlet and an air outlet, and a fan disposed within the housing; a gas pipeline adapted to connect to a gas source and the stove; and a gas generator disposed within the stove cabinet, comprising a gas chamber and a generator assembly, wherein the gas chamber is connected to the gas pipeline, an igniter is disposed within the gas chamber, and the igniter is connected to the gas ignition switch; when the gas ignition switch is turned on, the gas in the gas chamber burns and expands; the generator assembly comprises a stationary component and a moving component capable of moving with the gas during combustion and expansion; the stationary component is one of a magnet and a generator coil, and the moving component is the other of a magnet and a generator coil; the generator coil is connected to the fan.

[0006] Furthermore, the gas chamber has a gas inlet and an exhaust gas outlet, with the exhaust gas outlet higher than the gas inlet. The gas inlet is connected to a gas pipeline. The power generation components include:

[0007] The piston is vertically mounted in the gas chamber, and is in sealed contact with the side wall of the gas chamber. The piston is connected to the moving parts.

[0008] Furthermore, a one-way valve is provided at the gas inlet, and the gas generator also includes a sensor and a controller. The sensor can detect the piston's downward movement, and the controller is communicatively connected to the one-way valve and the sensor, and can control the one-way valve to open when the sensor detects the piston's downward movement.

[0009] Furthermore, the sensor includes:

[0010] The transmitter is fixedly mounted on either the wall of the gas chamber or the piston.

[0011] A receiver is fixedly mounted on the wall of the gas chamber and on another piston, and is adapted to receive signals transmitted by the transmitter.

[0012] Furthermore, the power generation assembly also includes a battery, which is connected to the power generation coil.

[0013] Furthermore, the range hood includes a control board connected to the fan, and an electrical box is also provided on the cooktop. One end of the electrical box is connected to the generator coil and the battery, and the other end of the electrical box is connected to the control board.

[0014] Furthermore, a cooling device is installed inside the stove cabinet to cool the gas generator.

[0015] Furthermore, the cooling device is a cooling fan.

[0016] Furthermore, an air intake grille is provided at the air intake.

[0017] Furthermore, the range hood also includes a cover plate disposed on the housing and adapted to cover the air intake grille, the cover plate having a first state of exposing the air intake grille and a second state of covering the air intake grille.

[0018] Furthermore, the kitchen cabinet is equipped with storage structures.

[0019] The present invention has the following advantages:

[0020] As can be seen from the above technical solution, the range hood and stove assembly of the present invention mainly includes a stove cabinet, a range hood, a gas pipeline, and a gas generator. During cooking, the gas pipeline provides gas to the stove. Turning on the stove ignition switch allows the gas to burn. The range hood generates suction with the help of a fan, allowing cooking fumes to enter the casing through the air inlet and then be discharged through the air outlet. When power generation is needed, turning on the gas ignition switch causes the gas entering the gas chamber to burn and expand, causing moving parts to move relative to stationary parts, cutting magnetic field lines, and generating an induced current in the generator coil, thereby powering the fan. Therefore, by installing a gas generator inside the stove cabinet, existing gas can be used to generate electricity to power the range hood fan, thus drawing in and expelling cooking fumes. Even during power outages, fume extraction can continue, ensuring a clean and fresh kitchen environment. Attached Figure Description

[0035] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Example 1

[0037] Figure 1 A front view of the range hood and cooktop assembly according to Embodiment 1 of the present invention is shown. Figure 2 This is a side view of the range hood and cooktop assembly according to Embodiment 1 of the present invention. Figure 1 and Figure 2As shown, the range hood and stove assembly 100 of this embodiment mainly includes a stove cabinet 2, a range hood 1, a gas pipeline 4, and a gas generator. The stove cabinet 2 is equipped with a stove 21, a stove ignition switch 22, and a gas ignition switch 103. The range hood 1 is located above the stove cabinet 2. The range hood 1 includes a housing 11 with an air inlet and an air outlet, and a fan 302 disposed within the housing 11. The gas pipeline 4 is adapted to connect to a gas source and the stove 21. The gas generator is disposed within the stove cabinet 2 and includes a gas chamber 601 and a generator assembly 602. The gas chamber 601 is connected to the gas pipeline 4, and an igniter 6021 is disposed within the gas chamber 601. The igniter 6021 is connected to the gas ignition switch 103. When the gas ignition switch 103 is turned on, the gas in the gas chamber 601 burns and expands. The generator assembly 602 includes a stationary component and a moving component that moves with the gas during combustion and expansion. The stationary component is either a magnet or a generator coil. The moving part is either a magnet or a power generation coil. The power generation coil is connected to the fan 302. Preferably, the air inlet may be provided with an air inlet grille 12. The air inlet grille 12 allows fumes to pass through and enter the housing 11, while preventing foreign objects from entering the housing 11 and damaging the fan, or preventing the user's hand from being injured by the fan when reaching into the housing 11. The gas used is preferably, but not limited to, natural gas or coal gas.

[0038] As can be seen from the above technical solution, the range hood and stove assembly 100 of the present invention mainly includes a stove cabinet 2, a range hood 1, a gas pipeline 4, and a gas generator. During cooking, the gas pipeline 4 provides gas to the stove 21. Turning on the stove ignition switch 22 allows the gas to burn. The range hood 1 generates suction with the help of the fan 302, allowing cooking fumes to enter the housing 11 through the air inlet and then be discharged through the air outlet. When power generation is needed, turning on the gas ignition switch 103 causes the gas entering the gas chamber 601 to burn and expand, causing the moving parts to move relative to the stationary parts, cutting magnetic field lines, and generating an induced current in the generator coil, thereby powering the fan 302. Therefore, by installing a gas generator inside the stove cabinet 2, when there is a power outage, the existing gas can be used to generate electricity to power the fan 302 of the range hood 1, thereby drawing in and expelling cooking fumes. This ensures a clean and fresh kitchen environment even during power outages. When there is no power outage, the fan 302 can be powered by an external power source, or the fan 302 can be powered by an external power source or a gas generator.

[0039] like Figure 5 As shown, the top of the stove cabinet 2 is the panel 200, and the stove 21, stove ignition switch 22, and gas ignition switch 103 are all located on the panel 100.

[0040] Based on the above embodiments, in a preferred embodiment, the gas chamber 601 has a gas inlet 6011 and an exhaust gas outlet 6012, the exhaust gas outlet 6012 is higher than the gas inlet 6011, the gas inlet 6011 is connected to the gas pipeline 4, the power generation component 602 further includes a piston 6022, the piston 6022 is vertically and vertically disposed in the gas chamber 601, the piston 6022 is in sealed contact with the side wall of the gas chamber 601, and the piston 6022 is connected to the moving component. In this embodiment, when the gas ignition switch 103 is turned on, the igniter 6021 ignites, and the gas located below the piston 6022 in the gas chamber 601 burns and expands. The piston 6022 moves upward. After some exhaust gas is discharged through the exhaust outlet 6012, the piston 6022, whose weight is greater than the pressure of the gas chamber 601, descends and compresses the gas. The pressure of the gas chamber 601 rises and the temperature has not yet dropped. The gas entering the gas chamber 601 burns and explodes again, doing work. This causes the piston 6022 to move up and down in a cycle. While the piston 6022 moves up and down, it drives the moving parts to move relative to the stationary parts, cutting the magnetic field lines and generating an induced current in the generator coil, thereby supplying power to the main fan 302.

[0041] Specifically, the magnet can be set to stand still, connecting the piston 6022 to the generator coil, or the generator coil can be set to stand still, connecting the piston 6022 to the magnet.

[0042] like Figure 3 As shown, the gas pipeline 4 includes a first gas pipe section 401 located inside the stove cabinet 2 and near the bottom, and a second gas pipe section 402 connected to the first gas pipe section 401 via a first tee connector 403. The first gas pipe section 401 is horizontally arranged, and the pipe end 4011 of the first gas pipe section 401 is sealed with sealant 4012 to prevent leakage. In other embodiments, the sealant 4012 can also be replaced by a sealing ring. The second gas pipe section 402 is vertically arranged, and the other end of the first tee connector 403 is connected to the gas inlet 6011 of the gas chamber 601. There are two stoves 21 in total. The top of the second gas pipe section 402 is provided with a second tee connector 404, and the other two ends of the second tee connector 404 are respectively connected to one stove 21.

[0043] Based on the above embodiments, in a preferred embodiment, a one-way valve is provided at the gas inlet 6011. The gas generator also includes a sensor 8 and a controller. The sensor 8 can detect the downward movement of the piston 6022. The controller is communicatively connected to the one-way valve and the sensor 8, and can control the one-way valve to open when the sensor 8 detects the downward movement of the piston 6022. In this embodiment, when the piston 6022 descends, gas can be automatically supplied to the gas chamber 601, thereby compressing the gas by the piston 6022, which is beneficial to the combustion and expansion of the gas. The controller may include a programmable logic controller (such as a PLC or CPU), a memory, and electronic components connected to the programmable logic controller, which are well known to those skilled in the art and will not be described in detail here.

[0044] Among them, sensor 8 can be a distance sensor 8. The marking end of the distance sensor 8 can be set on the end of piston 6022, and the sensing end can be set on the bottom wall of gas chamber 601. When the marking end is detected to be getting closer and closer to the sensing end, it indicates that piston 6022 is moving downward.

[0045] In such Figure 6 In the illustrated embodiment, sensor 8 includes a transmitter 81 and a receiver 82. The transmitter 81 is fixedly disposed on either the wall of the gas chamber 601 or the piston 6022. The receiver 82 is fixedly disposed on the other of the gas chamber 601 and the piston 6022, and is adapted to receive signals emitted by the transmitter 81. When the distance between the transmitter 81 and the receiver 82 decreases, it indicates that the piston 6022 is moving downwards. When the distance between the transmitter 81 and the receiver 82 increases, it indicates that the piston 6022 is moving upwards.

[0046] In this embodiment, the power generation component 602 also includes a storage battery connected to the power generation coil. In this implementation, the electrical energy generated can be stored in the storage battery. During power outages or when the battery has sufficient charge, the storage battery can be used to power the fan 302, which helps save energy.

[0047] Specifically, when the power generation component 602 includes a battery, the battery can store the electrical energy generated by the gas generator when there is no power outage, and immediately supply power to the fan 302 during a power outage, eliminating the need for users to wait for the gas generator to generate electricity, thus improving the user experience. When both power supply methods are used simultaneously, external power allows the range hood to start quickly, and then the electrical energy generated by the gas generator sustains the operation of the fan 302. For example, when the user is cooking on low to medium heat, the stove 21 consumes less gas, and the gas supplied by the gas pipeline 4 can simultaneously meet the needs of both the gas stove and the gas generator. When the user is cooking on high heat, the gas is primarily used to supply the stove 21, and the electrical energy required for the motor operation is mainly supplied by external power. When there is a power outage and high heat is required, the gas can primarily be used to supply the stove 21, and the battery can supply power to the fan 302.

[0048] In this embodiment, the range hood 1 also includes a control board 14. The control board 14 is connected to the fan 302. The cooktop 2 also has an electrical box 23. One end of the electrical box 23 is connected to a generator coil and a battery. The other end of the electrical box 23 is connected to the control board 14. For example, one end of the electrical box 23 may have multiple terminals, and the other end may have multiple terminals, with the terminals at both ends of the electrical box 23 connected one-to-one by wires. The generator coil and the battery can be plugged into the terminals at one end of the electrical box 23. The control board 14 can be plugged into the terminals at the other end of the electrical box 23, facilitating connection. The control board 14 may be connected to a charging plug, which can connect to an external power source, thus powering the fan 302 when there is no power outage. The control board 14 may include a programmable logic controller (PLC or CPU), a memory, and electronic components connected to the programmable logic controller, which are well known to those skilled in the art and will not be described in detail here.

[0049] In this embodiment, the stove cabinet 2 is equipped with a cooling device that can cool the gas generator, thereby improving its safety. The cooling device is preferably, but not limited to, a liquid cooling device or an air cooling device. For example, in this embodiment, the heat dissipation device is a cooling fan 71.

[0050] In this embodiment, the range hood 1 further includes a cover plate 13 disposed on the housing 11 and adapted to cover the air inlet grille 12. The cover plate 13 has a first state exposing the air inlet grille 12 and a second state covering the air inlet grille 12. When the cover plate 13 is in the first state, it can close the air inlet grille 12 to prevent foreign objects from entering the housing 11. When the cover plate 13 is in the second state, the range hood 1 can extract cooking fumes and ensure a fresh environment in the kitchen.

[0051] In this embodiment, as Figure 4As shown, the cabinet 2 may optionally include a storage structure 7. The storage structure 7 can be used to store tableware and other items.

[0052] Example 2

[0053] like Figure 7 and Figure 8 As shown, the difference between Embodiment 2 and Embodiment 1 is that the gas used is coal gas, and the storage structure 7 can be used to accommodate a coal gas storage tank. In this case, the gas pipeline section 401 can be connected to the coal gas storage tank and use the coal gas to generate electricity for the fan 302.

[0054] As can be seen from the above technical solution, the range hood and stove assembly 100 of this embodiment can solve the defect of the range hood and stove assembly 100 in the prior art that cannot guarantee a clean and fresh kitchen environment when the power is off, thereby providing a range hood and stove assembly 100 that can use the range hood 1 when the power is off.

[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
