Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, and in particular to a multi-channel range hood. Background Art

[0002] Related art all-in-one island units integrate an electric stove and range hood into the cooktop. The generated fumes are absorbed by an internal filter module, leaving only clean air. This air is then exhausted into the kitchen, creating a continuous internal circulation system. Related art all-in-one island units have relatively simple functions, for example, their exhaust schemes primarily rely on a single internal circulation system.

[0003] The inventors have found that, especially when the concentration of oil smoke generated by cooking is relatively high, the exhaust solution of the island-type all-in-one machine is still internal circulation, and large oil smoke means more condensed oil. This places high demands on the filter module inside the island-type all-in-one machine, and also requires more frequent replacement of the filter module. Utility Model Content

[0048] The overall structure, working principle and technical effects of the multi-channel range hood 010 provided by the present invention are described in detail below through embodiments and in conjunction with the accompanying drawings.

[0049] Please refer to Figure 1 The multi-channel range hood 010 provided by the present invention can realize different smoke exhaust modes for different cooking scenes, thereby reducing the accumulation of oil smoke inside the range hood and reducing the frequency of replacing the filter module.

[0050] Please refer to Figure 1 - Figure 4 The utility model proposes a multi-channel range hood 010, comprising:

[0051] Heating module 100, please refer to Figure 1 - Figure 2 , the heating module 100 is used to heat the pot 012;

[0052] Fan module 200, please refer to Figure 3 The fan module 200 is provided with a first air inlet 211 and an air outlet 212 which are connected to each other, and a sensor for detecting the concentration of oil smoke is provided in the fan module 200;

[0053] Exhaust module 300, please refer to Figure 4 The exhaust module 300 is provided with a second air inlet 311, a first air outlet 312 and a second air outlet 313 that are connected to each other, and the air outlet 212 is connected to the second air inlet 311; the exhaust module 300 is provided with a first adjusting member 330 connected to the sensor, and the first adjusting member 330 closes the second air outlet 313 or the first air outlet 312 to allow the oil smoke to be discharged from the first air outlet 312 or the second air outlet 313.

[0054] It is understood that by providing a sensor to detect the concentration of oil smoke entering the fan module 242, and by providing an exhaust module 300 and a first adjustment member 330, the exhaust module 300 is provided with a first exhaust port 312 and a second exhaust port 313. The first adjustment member 330 is connected to the sensor and closes the first exhaust port 312 or the second exhaust port 313 according to the oil smoke concentration detected by the sensor, so that the first exhaust port 312 or the second exhaust port 313 can exhaust oil smoke of different concentrations. In this way, different exhaust modes can be implemented according to different cooking scenarios, thereby reducing the accumulation of oil smoke inside the range hood and the frequency of replacing the filter module. At the same time, it can avoid the high oil smoke content and unpleasant odor of the air discharged into the room due to the single internal circulation and the failure to replace the filter and adsorption modules in time.

[0055] In this embodiment, the multi-channel range hood 010 is installed on the stove. Figure 1 and Figure 2 The stove includes a main body and a stove top 011 fixed on the main body; wherein, the heating module 100, the fan module 200 and the exhaust module 300 are all arranged inside the stove and at the bottom of the stove top 011, and the heating module 100 and the exhaust module 300 are adjacently arranged and fixedly connected to the bottom of the stove top 011.

[0056] Please refer to Figure 2 The stove top 011 is provided with an opening 0111 corresponding to the first air inlet 211 so that the oil smoke generated when the heating module 100 heats the pot 012 for cooking can enter the fan module 200 through the opening 0111 .

[0057] In this embodiment, the multi-channel range hood 010 includes a heating module 100 .

[0058] Please refer to Figure 2 The heating module 100 is used to heat the pot 012, and the food inside the pot 012 generates oil smoke or water vapor when heated.

[0059] Alternatively, see Figure 2 The heating module 100 can be an induction cooker built into the bottom of the stove top 011, or a gas heating device set on the stove top 011.

[0060] In this embodiment, the multi-channel range hood 010 includes a fan module 200 .

[0061] Please refer to Figure 2 and Figure 3 ,in, Figure 3 The solid line with arrows in the figure is used to illustrate the flow direction of oil smoke in the fan module 200.

[0062] The fan module 200 is configured to generate negative pressure using the fan 242 to draw the oil smoke or water vapor into the fan module 200 and discharge the oil smoke or water vapor into the exhaust module 300 .

[0063] In this embodiment, the fan module 200 includes a housing 210 and a flow guide structure 220 and a fan structure 240 disposed in the housing 210; Figure 3 , an air inlet cavity is formed inside the shell 210, and a first air inlet 211 and an air outlet 212 are provided on the shell 210; wherein, please refer to Figure 2 The housing 210 is mounted on the bottom of the stove top 011 and the first air inlet 211 is arranged relative to the opening 0111 of the stove top 011 so that oil smoke or water vapor can enter the housing 210. The air outlet 212 is opened on the side wall of the housing 210. Figure 3 The guide structure 220 is arranged corresponding to the first air inlet 211 and is fixedly connected to the stove top 011. The guide structure 220 is surrounded by a filter structure 230. The fan structure 240 is arranged adjacent to the guide structure 220. The fan structure 240 is fixedly connected to the bottom of the stove top 011, and the output end of the fan structure 240 is arranged relative to the air outlet 212.

[0064] Alternatively, see Figure 3 The guide structure 220 can be an annular mounting portion, and an impeller structure is fixedly connected inside the annular ring portion; accordingly, the filtering structure 230 is also annular, and one end of the filtering structure 230 is connected to the annular mounting portion, and the other end is connected to the inner bottom wall of the shell 210.

[0065] Alternatively, see Figure 3 The filter structure 230 may be a filter net, and the filter structure 230 is used to filter the oil smoke, so that the oil smoke and the filter structure 230 collide preliminarily, and large particles of oil smoke droplets are condensed on the filter structure 230.

[0066] Alternatively, see Figure 3 The fan structure 240 is used to generate negative pressure through airflow. The fan structure 240 includes a fan box 241 and a fan 242 disposed in the fan box 241. Figure 2 and Figure 3 The fan box 241 is fixed to the bottom of the stove top 011, and the fan box 241 is suspended in the shell 210 so that the bottom of the fan box 241 and the inner wall of the shell 210 leave space for arranging the sensor; at the same time, please refer to Figure 3A cavity is formed inside the fan box 241, and an inlet (not shown) and an outlet 2411 are provided on the fan box 241. The outlet 2411 is provided on the rear side wall of the fan box 241 and is arranged opposite to the air outlet 212, and the inlet is arranged at the bottom of the fan box 241; the fan box 241 is provided with a mounting portion for installing the fan 242 at the inlet, and the fan 242 is installed in the mounting portion so that the impeller 2422 of the fan 242 is arranged close to the inlet.

[0067] Please refer to Figure 3 The fan 242 includes a motor 2421 and an impeller 2422 arranged on the output shaft of the motor 2421, and the motor 2421 is fixed on the mounting portion.

[0068] It is understandable that please refer to Figure 3 The motor 2421 drives the impeller 2422 to rotate and generate airflow. Driven by the airflow, the oil smoke or water vapor enters the fan box 241 from the inlet and is thrown out from the outlet 2411. The thrown oil smoke or water vapor enters the exhaust module 300 from the air outlet 212.

[0069] In this embodiment, the multi-channel range hood 010 includes a sensor (not shown).

[0070] Among them, the sensor is used to detect the concentration of oil smoke.

[0071] In this embodiment, the sensor is disposed in the housing 210 and located at the bottom of the fan box 241 ; the sensor detects the concentration of oil smoke entering the fan structure 240 .

[0072] It can be understood that the sensor is communicated with the first adjusting member 330 and / or the second adjusting member 360, so that the first adjusting member 330 closes the first exhaust port 312 or the second exhaust port 313 according to the oil fume concentration detected by the sensor, so that the first exhaust port 312 or the second exhaust port 313 discharges oil fume of different concentrations; or the second adjusting member 360 closes the resistance-free outlet 341 and the deodorizing outlet 351 according to the oil fume concentration detected by the sensor, so that the resistance-free outlet 341 and the deodorizing outlet 351 discharge oil fume of different concentrations.

[0073] In this embodiment, the multi-channel range hood 010 includes an exhaust module 300 .

[0074] Please refer to Figure 1 and Figure 4 The exhaust module 300 is provided with a first exhaust port 312 and a second exhaust port 313 to discharge oil smoke of different concentrations.

[0075] In this embodiment, please refer to Figure 1 and Figure 4The first exhaust vent 312 is connected to the outdoor environment, and the second exhaust vent 313 is connected to the indoor environment. It is understood that if the sensor detects that the oil fume concentration is too high, the air is discharged to the outdoor environment through the first exhaust vent 312, and the outdoor exhaust mode is selected; if the sensor detects that the oil fume concentration is within a normal value, the air is discharged to the indoor environment through the second exhaust vent 313, and the indoor circulation mode is selected.

[0076] In this embodiment, please refer to Figure 1 and Figure 4 The exhaust module 300 includes a first adjustment member 330, a first smoke pipe 310, and an external smoke exhaust pipe 320. The first smoke pipe 310 forms a cavity through which oil smoke circulates. A second air inlet 311 is provided at one end of the first smoke pipe 310, and a second air outlet 313 is provided at the other end, and the second air outlet 313 is connected to the indoor environment. The first air outlet 312 is provided on the side wall of the first smoke pipe 310, and the first smoke pipe 310 is connected to the housing 210 so that the air outlet 212 is connected to the second air inlet 311. The external smoke exhaust pipe 320 is connected to the first smoke pipe 310, and one end of the external smoke exhaust pipe 320 is connected to the first air outlet 312, while the other end of the external smoke exhaust pipe 320 is connected to the outdoor environment. A first adjustment member 330 is provided at the first air outlet 312.

[0077] Alternatively, see Figure 4 The first regulating member 330 includes a first valve 331 and a first driving member (not shown). The first driving member drives the first valve 331 to rotate to close the first exhaust port 312 or the second exhaust port 313. The shape of the first valve 331 matches the shape of the first exhaust port 312 and the second exhaust port 313. The first driving member drives the first valve 331 to rotate about a first axis 332 so that the first valve 331 can close the first exhaust port 312 or the second exhaust port 313. The first axis 332 can be set at the bottom transverse connection or the top transverse connection of the first smoke pipe 310 and the external smoke exhaust pipe 320.

[0078] Of course, in other embodiments, due to the difference in the positions of the first air outlet 312 and the second air outlet 313 in the smoke pipe, the setting position of the first axis 332 can be selected according to actual conditions.

[0079] Alternatively, see Figure 4 A degreasing element 370 is provided at the second air outlet 313. Accordingly, the length of the first smoke pipe 310 can be extended along the second air outlet 313. The degreasing element 370 is disposed within the extended section of the first smoke pipe 310 so that it can remove oil from the oil smoke discharged from the second air outlet 313. The degreasing element 370 can be an activated carbon module for degreasing.

[0080] It is worth mentioning that if the oil smoke concentration is at a normal value but the odor is strong, the oil smoke will still be discharged from the second exhaust port 313 and circulate in the room, thereby making the oil smoke content of the air discharged into the room higher and the odor unpleasant. Figure 5 and Figure 6 By connecting the resistance-free outlet 341 and the deodorization outlet 351 at the second air outlet 313, the oil smoke is discharged separately.

[0081] Further, see Figure 5 The exhaust module 300 further includes a second regulating member 360, a second smoke pipe 340, and a third smoke pipe 350. One end of the second smoke pipe 340 is connected to the second exhaust port 313, and the other end is a resistance-free outlet 341. One end of the third smoke pipe 350 is connected to the second exhaust port 313, and the other end is a deodorization outlet 351. The second regulating member 360 is disposed at the second exhaust port 313. The second regulating member 360 closes the resistance-free outlet 341 or the deodorization outlet 351, allowing the oil smoke to be discharged through the deodorization outlet 351 or the resistance-free outlet 341.

[0082] Please refer to Figure 5 The deodorizing outlet 351 is provided with a deodorizing element 380 for removing the smell of cooking fumes. The deodorizing element 380 absorbs the smell in the cooking fumes to prevent the cooking fumes from polluting the indoor air. Optionally, the deodorizing element 380 may be an activated carbon deodorizing module.

[0083] The second smoke pipe 340 and the third smoke pipe 350 are arranged at the second exhaust port of the first smoke pipe 310 at an angle; the angle can be selected from 30° to 180°.

[0084] Alternatively, see Figure 5 The second regulating member 360 includes a second valve 361 and a second driving member (not shown). The second driving member drives the second valve 361 to rotate about a second axis 362 to close the resistance-free outlet 341 or the deodorizing outlet 351. The second axis 362 can be located at the vertical connection between the second smoke pipe 340 and the third smoke pipe 350, or at the vertical connection between the first smoke pipe 310 and the second smoke pipe 340 or the third smoke pipe 350.

[0085] Understandably, see Figure 5 The second driver drives second valve 361 to rotate about second axis 362, closing either unobstructed outlet 341 or deodorizing outlet 351. This allows cooking fumes to be discharged through deodorizing outlet 351 after being deodorized by deodorizing element 380, or directly discharged through unobstructed outlet 341. This arrangement prevents the discharge of high-content and unpleasant-smelling cooking fumes into the room due to a single internal circulation system and the failure to replace deodorizing element 370 promptly, further maintaining a fresh indoor air environment.

[0086] See Figure 6 and Figure 7 The working principle and process of the multi-channel range hood 010 provided by the embodiment of the present invention are as follows: the operator operates the heating module 100 to heat the pot 012, and the food inside the pot 012 is heated to produce oil smoke or water vapor.

[0087] Please refer to Figure 3 When fan module 200 is in operation, motor 2421 drives impeller 2422 to rotate, generating airflow. This creates negative pressure inside fan module 200, drawing oil smoke or water vapor into fan module 200 under the guidance of flow guide structure 220. The oil smoke initially collides with filter structure 230, causing large oil smoke droplets to condense on filter structure 230. Furthermore, driven by the airflow, the oil smoke or water vapor enters fan housing 241 through the inlet and is ejected through outlet 2411. The ejected oil smoke or water vapor then enters exhaust module 300 through outlet 212.

[0088] At the same time, the sensor detects the concentration of oil smoke.

[0089] If the oil smoke concentration is greater than the normal value, the oil smoke is discharged externally: the first driving member drives the first valve 331 to rotate around the first axis 332, closing the second exhaust port 313 or the inner cavity of the first smoke pipe 310 located at the bottom of the second exhaust port 313, and the oil smoke enters the external exhaust pipe 320 from the first exhaust port 312 and is discharged into the public flue through the external exhaust pipe 320, and the oil smoke is discharged to the outdoor environment through the public flue.

[0090] If the oil fume concentration is normal, the oil fume enters the internal circulation mode: the first driving member drives the first valve 331 to rotate around the first axis 332, closing the first exhaust port 312, and the oil fume is adsorbed by the oil removal member 370 and discharged from the second exhaust port 313, and is discharged to the indoor environment through the second exhaust port 313.

[0091] Furthermore, the internal circulation mode has the following two exhaust modes:

[0092] If the odor of the oil smoke is strong, the second driving member drives the second valve 361 to rotate around the second axis 362 to close the resistance-free outlet 341, so that the oil smoke is adsorbed and deodorized by the deodorizing member 380 from the deodorizing outlet 351 and then discharged into the indoor environment.

[0093] If the cooking fume has no obvious odor, the second driving member drives the second valve 361 to rotate around the second axis 362 to close the deodorization outlet 351 so that the cooking fume is directly discharged from the resistance-free outlet 341 to the indoor environment.

[0094] In summary, the multi-channel range hood 010 provided by the present embodiment: by providing a sensor to detect the concentration of oil smoke entering the fan module 242; by providing an exhaust module 300 and a first adjustment member 330, the exhaust module 300 is provided with a first exhaust port 312 and a second exhaust port 313. The first adjustment member 330 is connected to the sensor and closes the first exhaust port 312 or the second exhaust port 313 according to the oil smoke concentration detected by the sensor, so that the first exhaust port 312 or the second exhaust port 313 exhausts oil smoke of different concentrations. In this way, different exhaust modes are implemented according to different cooking scenarios, thereby reducing the accumulation of oil smoke inside the range hood and the frequency of replacing the filter module. At the same time, it also avoids the high oil smoke content and unpleasant odor of the air discharged into the room due to the single internal circulation and the failure to replace the filter and adsorption modules in time.

[0095] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
