[0046] Embodiment

[0047] With the rapid development of society, people's requirements for the living standards at home are getting higher and higher, especially in terms of diet health, which is particularly prominent. High-quality ingredients and good cooking skills can bring people a feast of food, and 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.

[0048] Currently, integrated stoves have emerged on the market. An integrated stove is a kitchen appliance that integrates a range hood and a gas stove, and it has many advantages such as saving space, good oil fume extraction effect, energy saving, low carbon and environmental protection. In the prior art, the oil fume around the cooking appliance of the integrated stove is prone to diffusion or sinking, resulting in poor oil fume extraction effect of the integrated stove.

[0049] For this reason, this embodiment provides an integrated stove that can enhance the oil fume extraction effect.

[0050] In one embodiment, as Figures 1 to 11 shown, the integrated stove includes a main body structure 1, an air inlet hood 2, and a range hood assembly 3. Among them, an auxiliary air inlet 103 is provided at a position near the edge of the main body structure 1; the air inlet hood 2 is arranged above the main body structure 1, and a first air inlet 201 is provided on the air inlet hood 2; the range hood assembly 3 is arranged in the main body structure 1 and includes a main volute 301, a main fan 302, an auxiliary volute 303, an auxiliary impeller 304, and an exhaust passage 306. The main volute air inlet of the main volute 301 is communicated with the inside of the air inlet hood 2; the main fan 302 is arranged in the main volute 301; the auxiliary volute 303 is arranged on one side of the main volute 301, and the auxiliary volute 303 is connected to the main volute air outlet of the main volute 301 through a connection passage 305, and an auxiliary air inlet opposite to the auxiliary air inlet 103 is provided on the auxiliary volute 303; the auxiliary impeller 304 is arranged in the auxiliary volute 303; the exhaust passage 306 is connected to the exhaust port of the auxiliary volute 303.

[0051] In this embodiment, when the integrated range hood is working, the main fan 302 is powered on. The cooking fumes enter the air inlet hood 2 through the first air inlet 201 and then enter the main volute 301. After that, they enter the auxiliary volute 303 through the connecting channel 305. The cooking fumes push the auxiliary wind wheel 304 to rotate, and the kinetic energy of the cooking fumes is converted into the kinetic energy of the auxiliary wind wheel 304, causing the auxiliary wind wheel 304 to suck the cooking fumes through the auxiliary air inlet and the auxiliary air outlet 103. Finally, all the cooking fumes are discharged through the smoke exhaust channel 306. By using the cooking fumes inhaled through the first air inlet 201 to inhale the cooking fumes at the auxiliary air outlet 103, the smoke extraction effect is enhanced. At the same time, only the main fan 302 needs to be powered, which is beneficial to cost savings.

[0052] As Figure 1 shown, a lamp tube 203 is provided on the air inlet hood 2. When cooking, the lamp tube 203 can shine into the pot, and the cooking situation of the food in the pot can be clearly seen.

[0053] On the basis of the above embodiment, in a preferred embodiment, as Figure 8 and Figure 11 shown, two auxiliary air outlets 103 are symmetrically provided. Correspondingly, two auxiliary volutes 303 are provided and are symmetrically distributed on both sides of the main volute 301. In this embodiment, by providing two auxiliary air outlets 103, the cooking fumes on both sides of the stove 101 can be inhaled, ensuring the smoke extraction effect. As Figure 8 shown, the two auxiliary air outlets 103 are respectively provided at positions close to the left edge and the right edge of the main body structure 1. Correspondingly, as Figure 11 shown, the two auxiliary volutes 303 are symmetrically distributed on the left and right sides of the main volute 301. The connecting channel 305 is a three-way channel, one end is connected to the main volute air outlet, and the other two ends are respectively connected to the auxiliary volutes 303. In other alternative embodiments, only one or more auxiliary air outlets 103 can be provided.

[0054] On the basis of the above embodiment, in a preferred embodiment, smoke collecting hoods 307 are provided on both sides of the upper end of the main volute 301. The smoke collecting hoods 307 are hermetically connected to the inner wall of the main body structure 1. The main volute air inlet is located at the top of the main volute 301, and the main volute air outlet is located at the side of the main volute 301. The axis of the main fan 302 is vertically arranged. In this embodiment, the setting of the smoke collecting hoods 307 can ensure that the cooking fumes inside the air inlet hood 2 can only enter the main volute 301 and will not contaminate other components inside the main body structure 1.

[0055] Specifically, the smoke collecting hood 307 is a box-shaped structure with an open top. The cooking fumes inside the smoke collecting hood 307 are blocked by the bottom of the smoke collecting hood 307 and cannot continue to flow downward. They are also blocked by the side wall of the smoke collecting hood 307 and cannot flow toward the side direction. They can only flow into the main volute 301.

[0056] On the basis of the above-described embodiments, in a preferred embodiment, the axis of the auxiliary wind wheel 304 is horizontally arranged. In this embodiment, the oil fume flowing out of the main volute 301 axially drives the auxiliary wind wheel 304 to rotate through the connection channel 305, and the efficiency of converting the kinetic energy of the oil fume into the kinetic energy of the auxiliary wind wheel 304 is relatively high. In other alternative embodiments, the axis of the auxiliary wind wheel 304 can be vertically arranged.

[0057] On the basis of the above-described embodiments, in a preferred embodiment, the shape of the auxiliary volute 303 is semi-pear-shaped. As Figure 11 shown, the top surface of the auxiliary volute 303 is horizontally arranged, and the bottom surface of the auxiliary volute 303 includes an arc surface adapted to the shape of the wind wheel and a horizontal surface connected to the arc surface. In this embodiment, the auxiliary volute 303 can cover the auxiliary air inlet 103 to absorb the oil fume on both sides. At the same time, the volume of the auxiliary volute 303 is small, and the space inside the integrated range hood can be fully utilized.

[0058] On the basis of the above-described embodiments, in a preferred embodiment, a sliding cover 202 is provided on the air inlet cover 2. The sliding cover 202 is arranged to be able to slide up and down, and has an initial position for blocking the first air inlet 201 and a working position for exposing the first air inlet 201. In this embodiment, the setting of the sliding cover 202 enables the first air inlet 201 to be blocked when the range hood component 3 is no longer needed, thus making the appearance more beautiful. Of course, in other alternative embodiments, the sliding cover 202 may not be provided.

[0059] On the basis of the above-described embodiments, in a preferred embodiment, a second air inlet 104 is further provided on the main body structure 1. The second air inlet 104 is provided at a position near the bottom of the air inlet cover 2, and the main volute air inlet is also communicated with the second air inlet 104. As Figure 8 shown, the second air inlet 104 extends along a direction parallel to the length direction of the main body structure 1. The auxiliary air inlets 103 are distributed on the left and right sides of the cooking appliance, and the second air inlets 104 are distributed at the rear side of the cooking appliance. In this embodiment, the setting of the second air inlet 104 enables the oil fume at the rear side of the integrated range hood cooking appliance to be absorbed, further enhancing the oil fume suction effect.

[0060] On the basis of the above-described embodiments, in a preferred embodiment, a wind baffle 105 is provided at the second air inlet 104. The wind baffle 105 has a closed position for blocking the second air inlet 104 and an open position for exposing the second air inlet 104. In this embodiment, the setting of the wind baffle 105 can block the second air inlet 104 when the range hood component 3 is not working, making the appearance more beautiful. Of course, in other alternative embodiments, the wind baffle 105 may not be provided.

[0061] On the basis of the above-described embodiments, in a preferred embodiment, as Figure 9 shown, a stepped portion 2021 is provided near the lower end of the sliding cover 202, and a through hole adapted for the stepped portion 2021 to pass through is provided on the main body structure 1. When the sliding cover 202 is pulled down to the working position, the stepped portion 2021 abuts against the wind deflector 105 and opens the wind deflector 105 to the open position. In this embodiment, when the sliding cover 202 is pulled down, the stepped portion 2021 passes through the through hole on the main body structure 1 and presses down one side of the wind deflector 105, causing the other side of the wind deflector 105 to tilt upwards, thereby opening the second air inlet 104. Therefore, the first air inlet 201 and the second air inlet 104 can be exposed simultaneously, and the structure is simple and compact. When the sliding cover 202 returns to the initial position, as Figure 10 shown, the lower end of the sliding cover abuts against the upper end of the through hole, covering the through hole, and the appearance is beautiful. In other alternative ways, the first air inlet 201 and the second air inlet 104 can be opened separately.

[0062] As Figure 9 and Figure 10 shown, the sliding cover 202 includes a main body portion and a connecting portion provided at the lower end of the main body portion. The thickness of the connecting portion is less than the thickness of the main body portion, thereby forming a stepped portion 2021 with the main body portion. In other alternative embodiments, the sliding cover 202 may include a main body portion and a convex platform provided on the main body portion. The convex platform and the main body portion form a stepped portion 2021.

[0063] Based on the above embodiments, in a preferred embodiment, a stove 101, a stove ignition switch 102, and a gas ignition switch 106 are provided on the main body structure 1. The integrated stove further includes a gas pipeline 4 and a gas generator. The gas pipeline 4 is communicated with the stove 101; the gas generator is arranged inside the main body structure 1, and the gas generator includes a gas chamber 501 and a power generation assembly 502. The gas chamber 501 is connected to the gas pipeline 4, and an igniter 503 is arranged inside the gas chamber 501. The igniter 503 is connected to the gas ignition switch 106. When the gas ignition switch 106 is turned on, the igniter 503 ignites, and the gas in the gas chamber 501 burns and expands. The power generation assembly 502 includes a stationary part and a moving part that can move along with the gas combustion and expansion. The stationary part is one of a magnet and a power generation coil, and the moving part is the other of a magnet and a power generation coil. The power generation coil is connected to the main fan 302. In the existing integrated stoves, when there is a power outage in the area where the integrated stove is located, the integrated stove only has the function of a cooking stove, and the oil fumes around the cooking stove cannot be sucked in, so a clean and fresh kitchen environment cannot be guaranteed. In this embodiment, by arranging a gas generator inside the main body structure 1, the existing gas can be used for power generation to supply power to the main fan 302 of the oil fume machine assembly 3, so as to suck in and discharge the oil fumes. When power generation is required, the gas ignition switch 106 is turned on, the gas entering the gas chamber 501 burns and expands to do work, driving the moving part to move relative to the stationary part, cutting the magnetic induction lines, and an induced current is generated in the power generation coil, so as to supply power to the main fan 302.

[0064] Specifically, a panel 100 is provided on the main body structure 1, and the stove 101, the stove ignition switch 102, and the gas ignition switch 106 are all arranged on the panel 100.

[0065] Based on the above embodiments, in a preferred embodiment, the gas chamber 501 has a gas inlet 5011 and an exhaust gas outlet 5012. The exhaust gas outlet 5012 is higher than the gas inlet 5011. The gas inlet 5011 is connected to the gas pipeline 4. The power generation assembly 502 further includes a piston 5021. The piston 5021 is arranged in the gas chamber 501 in a liftable manner. The piston 5021 is in sealed contact with the side wall of the gas chamber 501, and the piston 5021 is connected to the moving part. In this embodiment, when the gas ignition switch 106 is turned on, the igniter 503 ignites, and the gas below the piston 5021 in the gas chamber 501 burns and expands, and the piston 5021 moves upward. After part of the exhaust gas is discharged through the exhaust gas outlet 5012, the self-weight of the piston 5021 is greater than the pressure of the gas chamber 501 and it descends to compress the gas. The pressure of the gas chamber 501 rises and the temperature has not decreased yet. The gas entering the gas chamber 501 burns and explodes again to do work, enabling the piston 5021 to move up and down in a cycle. While the piston 5021 moves up and down, it will drive the moving part to move relative to the stationary part, cut the magnetic induction lines, and an induced current is generated in the power generation coil, so as to supply power to the main fan 302.

[0066] As Figure 5 shown, the gas pipeline 4 includes a first gas pipeline section 401 located inside the main structure 1 and near the bottom, and a second gas pipeline section 402 connected to the first gas pipeline section 401 through a first three-way joint 403. The first gas pipeline section 401 is horizontally arranged, and the pipe head 4011 of the first gas pipeline section 401 is sealed with a sealant 4012. The second gas pipeline section 402 is vertically arranged, and the other end of the first three-way joint 403 is connected to the gas inlet 5011 of the gas chamber 501. There are two stoves 101 in total. A second three-way joint 404 is provided at the top end of the second gas pipeline section 402, and the other two ends of the second three-way joint 404 are respectively connected to a stove 101. The position of the second three-way joint 404 is above the connection channel 305 and does not interfere with the main volute 301 and the connection channel 305.

[0067] Specifically, the magnet can be set stationary, with the piston 5021 connected to the power generation coil, or the power generation coil can be set stationary, with the piston 5021 connected to the magnet.

[0068] Based on the above embodiments, in a preferred embodiment, a check valve is provided at the gas inlet 5011. The gas generator further includes a sensor and a controller. The sensor can detect the downward movement of the piston 5021. The controller is communicatively connected to the check valve and the sensor, and can control the opening of the check valve when the sensor detects the downward movement of the piston 5021. In this embodiment, when the piston 5021 moves downward, the gas can be automatically controlled to be introduced into the gas chamber 501, so that the piston 5021 compresses the gas, which is beneficial to the combustion and expansion of the gas.

[0069] Among them, the sensor can be a distance sensor. The marked end of the distance sensor can be provided at the end of the piston 5021, and the sensing end can be provided on the bottom wall of the gas chamber 501. When it is detected that the distance between the marked end and the sensing end is getting closer, it indicates that the piston 5021 is moving downward.

[0070] Based on the above embodiments, in a preferred embodiment, the gas generator further includes a storage battery, and the storage battery is connected to the power generation coil. In this embodiment, the electric energy generated by power generation can be stored in the storage battery. When there is a power outage or when the storage battery is fully charged, the storage battery can be used to supply power to the main blower 302, which is beneficial to saving electric energy.

[0071] Based on the above embodiments, in a preferred embodiment, a storage cabinet 6 is further provided inside the main structure 1. In this embodiment, the storage cabinet 6 can store food in it after cooking, improving the space utilization rate and function of the integrated stove. As Figure 1 shown, the storage cabinet 6 has a cabinet door 602.

[0072] Based on the above embodiments, in a preferred embodiment, the storage cabinet 6 includes an outer shell 603 and an inner shell 601. The inner shell 601 is adapted to place items. An exhaust gas channel is formed between the outer shell 603 and the inner shell 601. The exhaust gas channel has an exhaust gas inlet and an exhaust gas outlet 9. The exhaust gas inlet is connected to the exhaust gas outlet 5012 of the gas chamber 501 through an exhaust gas pipe 7, and the exhaust gas outlet 9 is connected to the smoke exhaust channel 306 through an exhaust pipe 8. In this embodiment, by forming an exhaust gas channel between the outer shell 603 and the inner shell 601, the exhaust gas formed after gas combustion can flow through the exhaust gas channel and finally be discharged through the smoke exhaust channel 306. Thus, the heat of the exhaust gas can be used to keep the food in the inner shell 601 warm, giving users a good food experience. At the same time, the reuse of the exhaust gas is realized, which is energy-saving and environment-friendly.

In this embodiment, by arranging the strip-shaped grooves 6010 on the outer wall of the inner shell 601, the flow rate of the exhaust gas in the exhaust gas channel is slowed down, thereby increasing the contact duration of the exhaust gas with the inner shell 601, facilitating the retention of the heat in the exhaust gas on the outer surface of the inner shell 601, and thus ensuring the heat preservation effect.

[0077] Based on the above embodiments, in a preferred embodiment, as Figure 12As shown in the figure, the wall surface of the inner shell 601 opposite to the exhaust gas pipe 7 is the first wall surface 6011, the wall surface opposite to the exhaust pipe 8 is the second wall surface 6012, the wall surface opposite to the second wall surface 6012 is the third wall surface 6013. The strip-shaped grooves 6010 on the first wall surface 6011, the top wall surface 6014 and the bottom wall surface 6015 extend horizontally, and the strip-shaped grooves 6010 on the second wall surface 6012 and the third wall surface 6013 extend vertically. In this embodiment, it can ensure that the exhaust gas fully contacts the inner shell 601 for heat exchange and ensure the heat preservation effect.
