[0052] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0053] The following description of a range hood according to an embodiment of the present invention is with reference to the accompanying drawings.

[0054] like Figures 1-17 As shown, the range hood according to an embodiment of the present invention includes a first main body 110 and a display screen assembly 200.

[0055] The first main body 110 defines a receiving cavity 101 with a lower opening and a first smoke chamber 114 with a lower opening. The receiving cavity 101 is located in front of the first smoke chamber 114. The lower opening of the first smoke chamber 114 forms a first smoke inlet 112. Oil fumes can enter the first smoke chamber 114 from the first smoke inlet 112 and be discharged by the range hood.

[0056] The receiving cavity 101 is positioned in front of the first smoking cavity 114 to separate the first smoking port 112 from the lower opening of the receiving cavity 101, so as to prevent oil fumes from entering the receiving cavity 101 from the lower opening and polluting the environment inside the receiving cavity 101.

[0057] The display assembly 200 is disposed on the first main body 110. The display assembly 200 is movably disposed on the first main body 110 between a first position and a second position. In the first position, the display assembly 200 is housed in the receiving cavity 101 so that the display assembly 200 can be stored when it is not needed. This not only increases the user's operating space and prevents the display assembly 200 from obstructing the user's operation, but also protects the display assembly 200 from pollution caused by oil fumes.

[0058] Specifically, by moving the display assembly 200 to the first position, the display assembly 200 can be stored away, so that the display assembly 200 will not occupy the user's operating space. In other words, the size of the display assembly 200 on the range hood 1 can be set to be larger, which makes it easier to display more content on the display assembly 200 and improve the user experience.

[0059] In the second position, the display assembly 200 extends out of the receiving cavity 101 from the lower opening of the receiving cavity 101, making it convenient for the user to view the content on the display assembly 200. In some embodiments, the user can achieve visual interaction through the display assembly 200, such as viewing recipes and cooking simultaneously through the display assembly 200, conducting remote video chats through the display assembly 200 while cooking, or conducting live broadcasts using the display assembly 200 while cooking.

[0060] In addition, when the display assembly 200 is in the second position, it can also block the oil fumes, prevent the oil fumes from directly contacting the user's face, and prevent the oil fumes from spreading outward.

[0061] In other embodiments, the range hood 1 can be connected to other home appliances via a network, such as a microwave oven, rice cooker, oven, etc. The display screen assembly 200 can display the status of home appliances, allowing users to control other home appliances while cooking, making it easier for users to focus more on cooking.

[0062] Furthermore, the range hood 1 can be connected to devices such as electronic doorbells, security cameras, and air conditioners via a network. When a guest rings the doorbell, the user in the kitchen can directly view the footage captured by the security camera through the display screen component 200 and then operate the door lock, allowing the user to operate the door lock without leaving the kitchen. If the user notices that the indoor temperature is too high, or if they see that the indoor temperature is too high through the display screen component 200, they can operate the air conditioner through the display screen component 200. This setup allows users to focus more on cooking and improves the convenience of operation.

[0063] Therefore, the range hood according to the present invention can store and protect the display screen while increasing the user's operating space and improving the user experience.

[0064] The following description of a range hood according to a specific embodiment of the present invention is based on the accompanying drawings.

[0065] like Figures 1-17 As shown, the range hood according to an embodiment of the present invention includes a first main body 110 and a display screen assembly 200.

[0066] In some embodiments of the present invention, a slide rail 310 is provided in the receiving cavity 101, and the display assembly 200 is slidably engaged with the slide rail 310. The display assembly 200 can slide along the slide rail 310 to realize the sliding of the display assembly 200 between a first position and a second position.

[0067] In some embodiments, such as Figure 3 As shown, the display assembly 200 is formed into a rectangular plate structure. The receiving cavity 101 is provided with two slide rails 310. These two slide rails 310 are spaced apart on both sides of the width direction of the display assembly 200. For example, the width direction of the display assembly 200 extends in the left and right direction. There is a slide rail 310 on each side of the display assembly 200. These two slide rails 310 can support and guide the display assembly 200 to ensure that the display assembly 200 can slide stably and smoothly between the first position and the second position.

[0068] In some optional embodiments of the present invention, the length direction of the slide rail 310 is consistent with the length direction of the display assembly 200. The length of the slide rail 310 determines the distance that the display assembly 200 can move. Since the slide rail 310 is disposed in the receiving cavity 101, this arrangement can ensure that the display assembly 200 can be fully housed in the receiving cavity 101 in the first position, and that the display assembly 200 can extend out of the receiving cavity 101 from the lower opening of the receiving cavity 101 to the maximum extent in the second position.

[0069] In some embodiments, when the display assembly 200 is in the first position, the display assembly 200 is fully housed within the receiving cavity 101, at which time the upper end of the display assembly 200 can be flush with the upper end of the slide rail 310 (vertical direction as shown). Figure 5 As shown, the lower end of the display assembly 200 can be flush with the lower end of the slide rail 310, so that the display assembly 200 can be completely housed in the receiving cavity 101, avoiding the display assembly 200 from protruding out of the receiving cavity 101 and occupying the user's operating space.

[0070] In addition, housing the display assembly 200 in the receiving cavity 101 can protect the display assembly 200, so as to prevent objects in the external environment from scratching the display assembly 200 when the user is not using the display assembly 200, and to prevent oil fumes in the external environment from polluting the display assembly 200.

[0071] When the display assembly 200 is in the second position, such as Figure 1 , Figure 5 As shown, the display assembly 200 can extend out of the receiving cavity 101 to the maximum extent from the lower opening of the receiving cavity 101. At this time, the upper end of the display assembly 200 cooperates with the lower end of the slide rail 310 to ensure that the display assembly 200 extends out of the receiving cavity 101 to the maximum extent from the lower opening of the receiving cavity 101, so as to avoid the main body of the range hood 100 from blocking the main body of the display assembly 200, and to facilitate the user to view all the content displayed by the display assembly 200.

[0072] In some alternative embodiments of the present invention, such as Figure 5 , Figure 6 As shown, the range hood 1 also includes a display screen driving device 330, which is disposed in the receiving cavity 101 and connected to the display screen assembly 200. It is used to drive the display screen assembly 200 to move, so that the display screen assembly 200 can move along the slide rail 310 between a first position and a second position.

[0073] In some embodiments, the display drive device 330 includes a sliding motor, and the display assembly 200 is provided with a slide groove on the side facing the slide rail 310. The sliding motor can drive the display assembly 200 to slide along the slide rail 310 between a first position and a second position.

[0074] In other embodiments, the display drive device 330 includes gears and a motor, and a rack is provided on the slide rail 310. The motor can drive the gears to rotate. Through the cooperation of the gears and racks, the display drive device 330 can slide along the slide rail 310, and the display assembly 200 can slide between a first position and a second position along the slide rail 310.

[0075] In some embodiments, the display assembly 200 may not only stay at a first position and a second position, but may also stay at a position between the first position and the second position.

[0076] Specifically, the position of the display screen component 200 can be set according to the status of the range hood 1 and the cooking mode of the cooktop below the range hood 1. For example, when the range hood 1 is in the off state, the display screen component 200 can be set to the first position; when the range hood 1 is in the standby state, the display screen component 200 can be set to the first intermediate position between the first and second positions; when the cooktop is in the first cooking state, the display screen component 200 can be set to the second intermediate position between the first and second positions; and when the cooktop is in the second cooking state, the display screen component 200 can be set to the second position. The first and second cooking states can be states such as stir-frying or stewing.

[0077] In some examples, when the display assembly 200 is lowered to a position 40 mm away from the first position, a portion of the lower side of the display assembly 200 extends out of the receiving cavity 101. This portion can be used to display weather, time or other information, or for voice interaction or to play audio content.

[0078] In other examples, when the display assembly 200 descends to a position 300 mm away from the first position, a portion of the display assembly 200 extends out of the receiving cavity 101. The display assembly 200 can be used to display recipe tutorials, video content, etc., to achieve a more intuitive visual interaction. At this time, the display assembly 200 can also be used to isolate oil fumes.

[0079] In other examples, when the display assembly 200 descends to a position 400 mm away from the first position, the display assembly 200 can completely enclose the cooking fumes. At this time, the display assembly can display the status of the cooking ingredients, making it convenient for users to observe and control the cooking progress from a distance.

[0080] In summary, users can select the degree to which the display assembly 200 is exposed outside the receiving cavity 101 according to their own needs, so as to meet different user requirements.

[0081] In some optional embodiments of the present invention, a support portion 320 is further provided in the receiving cavity 101. The support portion 320 is arranged separately from the slide rail 310. The support portion 320 is located on one side of the display assembly 200 to support the display assembly 200 and ensure that the display assembly 200 can slide stably between the first position and the second position along the slide rail 310.

[0082] In some specific embodiments of the present invention, such as Figure 6As shown, the support part 320 is a roller. When the display screen assembly 200 slides along the slide rail 310, relative sliding occurs between the display screen assembly 200 and the roller. By setting the support part 320 as a roller, the friction between the support part 320 and the display screen assembly 200 can be reduced while ensuring the support effect, thereby reducing the wear caused by the support part 320 to the display screen assembly 200.

[0083] Specifically, when the display assembly 200 slides along the slide rail 310, the roller can rotate under the drive of the display assembly 200, so as to support the display assembly 200 while reducing the wear caused by the roller to the display assembly 200, thereby increasing the service life of the display assembly 200 and reducing costs.

[0084] In some embodiments, such as Figure 6 As shown, the display assembly 200 is sandwiched between the slide rail 310 and the roller. The slide rail 310 is located on the front side of the display assembly 200, and the roller is located on the rear side of the display assembly 200. The slide rail 310 and the roller together define the sliding path of the display assembly 200 to ensure that the display assembly 200 can slide smoothly between the first position and the second position.

[0085] In some alternative embodiments of the present invention, such as Figure 5 , Figure 6 As shown, the support part 320 is located in the lower part of the receiving cavity 101. The receiving cavity 101 is provided with a plurality of support parts 320. The plurality of support parts 320 are arranged at intervals along the width direction of the display assembly 200 to support the display assembly 200 at multiple positions, so as to ensure that the display assembly 200 can slide stably between the first position and the second position.

[0086] Specifically, in some embodiments, the support portion 320 is a roller, and the side of the display assembly 200 facing the support portion 320 is a plane. That is, the support portion 320 and the display assembly 200 are in line-plane contact. The support of a single support portion 320 for the display assembly 200 is not stable enough. Multiple support portions 320 are provided in the receiving cavity 101 along the width direction of the display assembly 200 to ensure the stability of the support of the support portion 320 for the display assembly 200, so as to prevent the display assembly 200 from falling off the slide rail 310 and ensure that the display assembly 200 can slide stably between the first position and the second position along the slide rail 310.

[0087] In some embodiments of the present invention, such as Figure 1 , Figure 5As shown, the receiving cavity 101 is located at the front of the range hood body 100, and the display screen assembly 200 extends from back to front and downwards at an angle, which facilitates the storage of the display screen assembly 200 and the viewing or use of the display screen assembly 200 by the user.

[0088] Specifically, when the display assembly 200 is in the first position, the display assembly 200 is tilted and stored in the receiving cavity 101. This arrangement makes it easier to make full use of the space in the receiving cavity 101 to store the display assembly 200, and to reduce the space occupied by the receiving cavity 101.

[0089] When the display assembly 200 is in the second position, the display assembly 200 extends out of the receiving cavity 101 from the lower opening of the receiving cavity 101. At this time, the display assembly 200 also extends downward from back to front outside the receiving cavity 101. That is to say, when the user is using the range hood 1, the user stands in front of the display assembly 200. At this time, the display assembly 200 extends downward from back to front, which makes it convenient for the user to view and use the display assembly 200.

[0090] In some embodiments of the present invention, such as Figure 3 , Figure 4 As shown, the first main body 110 is provided with a first camera assembly 340, which includes a first camera 341. The first camera 341 is arranged facing forward, so as to facilitate the shooting of the area in front of the first main body 110 through the first camera 341.

[0091] In some embodiments, when a user is cooking on the front side of the first main body 110, the first camera 341 can capture the user's every move, making it convenient for the user to live stream or record videos using the first camera 341.

[0092] In some embodiments, the first camera 341 is connected to the display assembly 200, allowing users to take pictures through the first camera 341 and view the content captured by the first camera 341 in a timely manner through the display assembly 200, or watch the video while recording, facilitating interaction between users and viewers during live streaming.

[0093] In some embodiments of the present invention, such as Figure 8As shown, the first camera assembly 340 also includes a camera driving device 342, which is connected to the first camera 341 to drive the first camera 341 to move between a storage position and a shooting position. In the storage position, the first camera 341 is housed in the receiving cavity 101 and located in front of the display assembly 200 to protect the first camera 341 from contamination by oil fumes or other pollutants when it is not in use, and to prevent objects in the external environment from scratching or damaging the first camera 341.

[0094] In the shooting position, the first camera 341 is exposed below the first main body 110 to avoid the first main body 110 from obstructing the shooting of the first camera 341, so that the first camera 341 can shoot clearly.

[0095] In some embodiments, such as Figure 8 , Figure 9 As shown, the camera driving device 342 can drive the first camera 341 to move in the vertical direction (vertical direction as shown in the image). Figure 8 As shown), the camera driving device 342 drives the first camera 341 to move upward to the storage position, as shown. Figure 8 As shown, the first camera 341 is housed within the receiving cavity 101. The camera driving device 342 can also drive the first camera 341 downwards to the shooting position, such as... Figure 9 As shown, the first camera 341 is exposed outside the first main body 110, so that it can capture images of the area in front of the first main body 110.

[0096] In some examples, such as Figure 8 , Figure 9 As shown, the first camera assembly 340 includes a guide rail 343, which is fixed on the first main body 110 and extends in the vertical direction. The camera driving device 342 includes a sliding motor, which cooperates with the guide rail 343 through a guide groove. The sliding motor can slide along the guide rail 343 to drive the first camera 341 to move in the vertical direction, thereby enabling the first camera 341 to move between the storage position and the shooting position.

[0097] Specifically, in some examples, such as Figure 9As shown, the first camera assembly 340 includes two guide rails 343, which are spaced apart along the width direction of the first camera assembly 340 and extend vertically. A sliding motor is fitted onto the two guide rails 343, and a guide groove is provided at the corresponding position of the sliding motor to cooperate with the guide rail 343, so as to realize the stable vertical movement of the sliding motor, and further drive the first camera 341 to move stably vertically, so as to realize the stable movement of the first camera 341 between the storage position and the shooting position.

[0098] In other examples, the first camera assembly 340 includes a guide rail 343 fixed to the first main body 110. The guide rail 343 is provided with a rack that extends in the vertical direction. The camera driving device 342 includes a gear and a motor. The motor can drive the gear to rotate. Through the cooperation of the gear and the rack, the camera driving device 342 can slide along the guide rail 343 to drive the first camera assembly 340 to slide in the vertical direction, thereby further enabling the first camera 341 to move between the storage position and the shooting position.

[0099] In some embodiments of the present invention, such as Figure 3 , Figure 10 As shown, the first main body 110 is also provided with a plurality of speakers 910. The plurality of speakers 910 are arranged at intervals along the width direction of the first main body 110. The speakers 910 can be used to play music, videos, etc., to facilitate users to realize voice interaction.

[0100] The inclusion of multiple speakers 910 facilitates expanding the sound playback range and enabling sound to be played from multiple channels to achieve a stereo effect. This also improves the sound quality of the speaker output and enhances the user experience.

[0101] In some embodiments, the width of the first main body 110 extends along the left-right direction (as shown in the left-right direction). Figure 10 As shown, four speakers 910 are provided in the cavity 101. The four speakers 910 are arranged at intervals in the first main body 110 in the left-right direction. The four speakers 910 can improve the sound output quality by being connected in parallel to achieve a four-channel stereo effect.

[0102] In some optional embodiments of the present invention, a plurality of speakers 910 are disposed within the receiving cavity 101 and located in front of the display assembly 200, which facilitates the synchronous output of images and sound and improves the user experience.

[0103] Specifically, the display assembly 200 can be used for playing videos, making video calls, etc., and the speaker 910 is used for sound output. Placing the speaker 910 in front of the display assembly 200 allows users to hear sound directly from the speaker 910, ensuring clear sound from the speaker. It also reduces sound latency during transmission, achieving synchronization between sound and image and improving the user experience.

[0104] In some alternative embodiments of the present invention, such as Figure 4 , Figure 10 As shown, the range hood also includes a sound guide plate 920, which is located on the lower side of the speaker 910 to seal the receiving cavity 101 and prevent dust and other pollutants from entering the receiving cavity 101 and contaminating the speaker 910.

[0105] In some embodiments, the length of the sound guide plate 920 extends along the width direction of the first main body portion 110, and a plurality of speakers 910 are spaced apart along the length direction of the sound guide plate 920, so as to protect the plurality of speakers 910 by the sound guide plate 920 and prevent objects in the external environment from scratching the speakers 910.

[0106] The sound guide plate 920 can be made of a sound-conducting and waterproof material, so as to protect the speaker 910 without affecting the transmission of sound by preventing oil fumes or water vapor from coming into contact with the speaker 910 when it flows upward, and to prevent water stains or oil fumes from damaging the speaker 910.

[0107] In some specific embodiments of the present invention, such as Figure 10 , Figure 11 As shown, the first camera assembly 340 is positioned above the center of the sound guide plate 920. The sound guide plate 920 has a corresponding clearance hole. When the first camera 341 is in the shooting position, it can pass through the clearance hole and protrude from the first main body 110, allowing it to take pictures. By providing the clearance hole, the first camera 341 can move smoothly between the storage position and the shooting position, preventing the sound guide plate 920 from obstructing the first camera 341 and affecting its shooting capabilities.

[0108] In some embodiments of the present invention, such as Figure 6 , Figure 13 As shown, the first main body 110 is provided with a second camera assembly 400. The second camera assembly 400 includes a second camera 430 and the second camera 430 is arranged downwards. The second camera 430 can capture images of the area below. For example, if the stove is arranged below the second camera 430, the second camera 430 can capture images of the user's cooking process.

[0109] In some embodiments, the second camera assembly 400 includes a plurality of second cameras 430, which are spaced apart along the width direction of the first main body 110. Since the range that each second camera 430 can capture is limited, setting up a plurality of second cameras 430 facilitates shooting from different angles and positions to fully record the user's cooking process.

[0110] In some examples, the width of the first main body 110 extends in the left-right direction, and three second cameras 430 are spaced apart in the width of the first main body 110. The range captured by these three second cameras 430 is not exactly the same, so as to fully record the user's cooking process from different angles and ranges.

[0111] The working status of the three secondary cameras 430 can be adjusted according to the user's needs. For example, the middle secondary camera 430 can be turned on, while the two secondary cameras on the left and right sides can be turned off to meet the user's needs for shooting from different angles and in different areas.

[0112] like Figure 13 As shown, in some optional embodiments of the present invention, the second camera assembly 400 further includes a light guide plate 410 and a light-emitting part 420. The light guide plate 410 has a mating hole 411 that runs vertically through the light guide plate. The second camera 430 is disposed above the light guide plate 410 and mates with the mating hole 411 to limit the position of the second camera 430, so that the second camera 430 can accurately help the user to film the cooking process. The mating hole 411 can limit the position of the second camera 430 on the one hand, and avoid the second camera 430 on the other hand, so as to prevent the reflector from blocking the second camera 430 and affecting the image capture of the second camera 430.

[0113] In other words, when users want to record the cooking process, they do not need to hold the camera while cooking. The second camera 430 on the range hood 1 can record the cooking process, freeing up the user's hands and improving the user experience.

[0114] The light-emitting part 420 is disposed on one side of the light guide plate 410. When the light emitted by the light-emitting part 420 shines on the light guide plate 410 from the edge, the light guide plate 410 can reflect the light to expand the illumination range of the light-emitting part 420, so that the light emitted by the light-emitting part 420 can achieve a uniform surface light source. On the one hand, it can provide illumination for the second camera 430 to capture images, and on the other hand, it can provide illumination for the user's cooking environment, making it easier for the user to observe the cooked food more accurately.

[0115] The color and brightness of the light emitted by the light-emitting part 420 are adjustable to meet different user needs.

[0116] In some embodiments, multiple second cameras 430 are paired with multiple mating holes 411 to capture images from different angles and positions, so as to fully record the user's cooking process.

[0117] In some specific embodiments of the present invention, a plurality of second cameras 430 are arranged at intervals along the length direction of the light guide plate 410, the length direction of the light guide plate 410 extends in the left-right direction, and the width direction of the light guide plate 410 extends in the front-back direction (as shown in the front-back direction). Figure 5 As shown, it should be understood that the above directional limitation is only for the convenience of describing the attached drawings and does not limit the actual installation position and direction of the range hood 1. The light-emitting part 420 is located on the rear side of the light guide plate 410 and extends along the length of the light guide plate 410. It utilizes the reflective properties of the light guide plate 410 to form a uniform surface light source to provide illumination for the second camera 430, avoiding blind spots that would prevent the second camera 430 from taking pictures normally due to insufficient light.

[0118] Arranging multiple second cameras 430 at intervals along the length of the light guide plate 410 facilitates the light guide plate 410 providing illumination to each second camera 430, enabling the second camera 430 to capture images clearly.

[0119] In some embodiments of the present invention, such as Figure 13 As shown, the second camera assembly 400 also includes a transparent protective plate 440, which covers the lower surface of the light guide plate 410. The transparent protective plate 440 protects the light guide plate 410, the second camera 430, and the light-emitting part 420 from external environmental impacts, preventing damage to the light guide plate 410, the second camera 430, and the light-emitting part 420.

[0120] In addition, the transparent protective plate 440 can also separate the light guide plate 410, the second camera 430 and the light-emitting part 420 from the oil fumes, so as to prevent the oil fumes from polluting the light guide plate 410, the second camera 430 and the light-emitting part 420, and affecting the imaging function of the second camera 430 and the lighting function of the light-emitting part 420.

[0121] In some optional embodiments of the present invention, the transparent protective plate 440 is a glass plate, so as to protect the light guide plate 410, the second camera 430 and the light-emitting part 420 without obstructing the second camera 430 and the light-emitting part 420, and without affecting the camera function of the second camera 430 and the lighting function of the light-emitting part 420.

[0122] The use of a glass plate as a transparent protective plate 440 enhances the aesthetics of the second camera assembly 400, while allowing users to directly clean the glass plate to keep the second camera assembly 400 clean.

[0123] In some optional embodiments of the present invention, the second camera component 400 is disposed in the receiving cavity 101 to protect the second camera component 400 and prevent other external objects from scratching or damaging the second camera component 400.

[0124] In addition, the second camera assembly 400 is located behind the display assembly 200 to capture images of the area behind the display assembly 200.

[0125] In some specific embodiments of the present invention, the first camera component 340 is disposed in front of the display component 200, and the first camera 341 is disposed facing forward, which can capture the area in front of the display component 200, such as capturing the user's face, so that the user can use the first camera 341 to conduct live broadcasts, etc.

[0126] The second camera assembly 400 is located behind the display assembly 200, and the second camera 430 is positioned downwards. It can capture images of the area behind the display assembly 200, such as the area around the stove, so as to capture the user's cooking process.

[0127] The first camera 341 and the second camera 430 are configured to capture images of multiple areas to meet different user needs. In some embodiments, both the first camera 341 and the second camera 430 are connected to the display screen assembly 200, allowing users to view the content captured by the first camera 341 and the second camera 430 through the display screen assembly 200, facilitating switching between multiple lenses and meeting different user needs.

[0128] In some embodiments of the present invention, such as Figure 12 As shown, the range hood 1 also includes a smoke-blocking component 500, which is located on one side of the second camera component 400. The smoke-blocking component 500 has an air duct inlet 510 and an air duct outlet 520. The smoke-blocking component 500 is used to guide the air entering the smoke-blocking component 500 from the air duct inlet 510 toward the air duct outlet 520 to form a smoke-blocking air curtain under the second camera component 400. The smoke-blocking air curtain isolates the second camera component 400 from the oil fumes, preventing the oil fumes from contaminating the second camera component 400.

[0129] In some embodiments, the range hood 1 includes a plurality of smoke-blocking components 500. The smoke-blocking components 500 are disposed on the side of the light guide plate 410 away from the light-emitting part 420 in the width direction. The plurality of smoke-blocking components 500 are spaced apart along the length direction of the light guide plate 410 to form a smoke-blocking air curtain that flows along the width direction of the light guide plate 410, so that the formed smoke-blocking air curtain can fully cover the lower side of the second camera component 400, fully isolate the oil fumes, and prevent the oil fumes from polluting the second camera component 400.

[0130] In some alternative embodiments of the present invention, such as Figure 12 As shown, the smoke barrier assembly 500 includes a housing 501, a first fan, and an air guide 503. An air duct inlet 510 is disposed in the housing 501, and the first fan is rotatably disposed inside the housing 501. An air duct outlet 520 is defined between the air guide 503 and the housing 501. The first fan can drive air near the smoke barrier assembly 500 to flow into the housing 501 from the air duct inlet 510 and out of the housing 501 from the air duct outlet 520 to form a smoke barrier air curtain.

[0131] In some examples, the length of the light guide plate 410 extends in the left-right direction, the width of the light guide plate 410 extends in the front-back direction, the housing 501 is disposed on the front side of the light guide plate 410, and the air guide 503 is disposed on the lower side of the housing 501. The air guide 503 can change the direction of airflow from the lower side of the housing 501, so that the formed smoke curtain can achieve the effect of isolating oil fumes.

[0132] Specifically, the air duct inlet 510 is located on the front side of the second camera assembly 400. Air can enter the air duct inlet 510 in the front-back direction and flow out from the lower side of the housing 501 in the up-down direction. Under the guidance of the air guide 503, the air flowing out from the lower side of the housing 501 changes from flowing in the up-down direction to flowing in the front-back direction. That is to say, the air flowing out from the air duct outlet 520 flows in the front-back direction to form a smoke-proof air curtain flowing along the width direction of the light guide plate 410. The smoke-proof air curtain is located on the lower side of the transparent protective plate 440 to isolate the transparent protective plate 440 from the oil fumes, further isolating the second camera assembly 400 from the oil fumes and preventing the oil fumes from contaminating the second camera assembly 400.

[0133] In some embodiments of the present invention, such as Figure 5 As shown, the display assembly 200 includes a display screen 210 and an air supply device 220. The display screen 210 is located in front of the first smoke inlet 112. This arrangement facilitates the user to view the content on the display screen 210 or operate the display screen 210. On the other hand, it separates the display screen 210 from the first smoke inlet 112 so that the oil fumes can enter the first smoke inlet 112 as much as possible, thus avoiding the oil fumes from polluting the display screen 210.

[0134] In addition, placing the display screen 210 in front of the first smoke inlet 112 can also block the fumes, prevent the fumes from directly contacting the user's face, and prevent the fumes from spreading outward.

[0135] Among them, such as Figure 7 As shown, the display assembly 200 has an air inlet 230, an air outlet 240, and an air duct 250. The air outlet 240 is located at the rear of the display 210. The air supply device 220 is used to guide the air entering the air duct 250 from the air inlet 230 toward the air outlet 240 to form an air curtain at the rear of the display 210. On the one hand, the air curtain separates the display 210 from the oil fumes to prevent the oil fumes from polluting the display assembly 200. On the other hand, the air curtain guides the oil fumes so that they can enter the first smoke inlet 112 along the flow direction of the air curtain.

[0136] In some embodiments, driven by the air supply device 220, air near the display screen 210 can enter the air duct 250 from the air inlet 230 and flow out from the air outlet 240 to form an air curtain. Driven by the air supply device 220, the air curtain can flow in a direction approximately parallel to the rear side of the display screen 210, so as to effectively separate the display screen 210 from the oil fumes and prevent the oil fumes from polluting the display screen 210.

[0137] In some embodiments of the present invention, the air inlet 230 forms an air inlet extending along the width direction of the display screen 210. This arrangement facilitates the expansion of the air inlet area and further facilitates the expansion of the area of ​​the formed air curtain.

[0138] In some embodiments, the width of the display screen 210 extends along the left-right direction (as shown in the left-right direction). Figure 1 As shown), the air inlet is located at the lower end of the display screen 210 (vertically as shown). Figure 1 As shown, it should be understood that the above directional limitation is only for the convenience of describing the attached drawings and does not limit the actual setting position and direction of the range hood 1. The air inlet extends in the left and right direction. This setting facilitates the expansion of the air intake area and further facilitates the expansion of the area of ​​the air curtain. The air curtain can cover the rear side of the display screen 210 as much as possible, so as to fully separate the display screen 210 from the oil fumes and avoid the oil fumes from polluting the display screen 210.

[0139] In some other embodiments of the present invention, the air inlet 230 includes a plurality of air inlets, which are spaced apart along the width direction of the display screen 210. This arrangement facilitates the uniform entry of air from the front side of the display screen 210 into the air duct 250 through the plurality of air inlets, so as to form a uniform air curtain on the rear side of the display screen 210.

[0140] In some alternative embodiments of the present invention, such as Figure 7As shown, a filter element 231 is provided at the air inlet 230 to filter the air entering from the air inlet 230, ensuring the cleanliness of the air entering the air duct 250, avoiding pollution of the environment inside the air duct 250, and at the same time facilitating the formation of a clean air curtain by using clean air, thus avoiding pollution of the display screen 210.

[0141] In some embodiments of the present invention, the air outlet 240 is located at the rear of the display screen 210 and is disposed near one end of the display screen 210 in the first direction. The air outlet 240 forms an air outlet, and the opening of the air outlet faces the other end of the display screen 210 in the first direction, so that the flow direction of the air curtain extends along the first direction, thereby maximizing the area of ​​the air curtain and ensuring that the air curtain can separate the display screen 210 from the oil fumes, thus preventing the oil fumes from polluting the display screen 210.

[0142] In some embodiments, the first direction extends along the length of the display screen 210, that is, the air inlet 230 extends along the width of the display screen 210, and the air duct 250 and the air outlet 240 also extend along the width of the display screen 210. At this time, air enters the air duct 250 uniformly from the air inlet 230 along the width of the display screen 210, and flows out uniformly from the air outlet 240 along the width of the display screen 210 under the drive of the fan, so that the formed air curtain can cover the width of the display screen 210.

[0143] Driven by the fan, the air flowing out from the air outlet 240 can flow along the length of the display screen 210. For example, the air supply device 220 is provided at the lower end of the display screen 210, and the air extends from bottom to top along the rear side of the display screen 210 so that the formed air curtain can cover the length of the display screen 210.

[0144] In summary, this arrangement allows the air curtain to completely cover the back of the display screen 210, thus separating the oil fumes from the display screen 210 and preventing the oil fumes from polluting the display screen 210.

[0145] In some embodiments of the present invention, such as Figure 2 As shown, the display screen 210 includes a display area 211 and a touch area 212. The display screen assembly 200 also includes a touch module 260, which is located on the rear side of the display screen 210 to form the touch area 212 on the display screen 210. Users can view temperature, recipes, videos, etc. through the display area 211, and users can operate the range hood 1, the display screen 210, or other devices through the touch area 212.

[0146] Furthermore, the touch module 260 is positioned on the rear side of the display screen 210, allowing users to control the display screen 210 or the range hood 1 from the touch area 212. This integrates display and operation through the display screen assembly 200, improving the aesthetics of the range hood 1. When cleaning the display screen 210, both the display area 211 and the touch area 212 can be cleaned simultaneously, facilitating cleaning of the range hood 1.

[0147] In some embodiments, the width of the display screen 210 extends along the left-right direction (as shown in the left-right direction). Figure 2 As shown, the touch area 212 extends in the left and right direction. This arrangement allows users to operate the display screen 210 or the range hood 1, etc., in the same area, making it convenient for users.

[0148] In some optional embodiments of the present invention, the touch module 260 is disposed near one end of the display screen 210 in a first direction, the first direction being the width or length direction of the display screen 210, so as to ensure the integrity of the display area 211 as much as possible, avoid the touch module 260 from affecting the content of the display area 211, and facilitate user use.

[0149] In some embodiments, such as Figure 2 , Figure 7 As shown, the first direction is the length direction of the display screen 210. The touch module 260 is located at the lower end of the display screen 210. The touch module 260 extends in the left and right direction to form a touch area 212 at the lower end of the display screen 210. The touch area 212 extends in the left and right direction to avoid the touch area 212 being too high, which would make it difficult for the user to operate the touch area 212.

[0150] In addition, setting the touch area 212 to extend in the left and right direction can maximize the range of the touch area 212 without affecting the range of the display area 212, making it convenient for users to operate the touch area 212.

[0151] In some alternative embodiments of the present invention, such as Figure 5 , Figure 7 As shown, the touch module 260 is sandwiched between the display screen 210 and the air supply device 220, so that the position of the touch module 260 is limited by the display screen 210 and the air supply device 220. At the same time, the air curtain can isolate the oil fumes from the touch module 260, so as to avoid the oil fumes from contaminating the touch module 260.

[0152] In some optional embodiments of the present invention, the display screen 210 is a transparent display screen, allowing the user's line of sight to pass through the transparent display screen and observe the area behind it to monitor the cooking process. This arrangement prevents the display screen 210 from interfering with the user's normal cooking, thus improving the user experience.

[0153] In some embodiments of the present invention, such as Figure 5 As shown, the first main body 110 is provided with a first smoke-blocking component 600, which can be switched between the state of opening the first smoke inlet 112 and the state of closing the first smoke inlet 112 to meet different user needs.

[0154] Among them, such as Figure 14 , Figure 15 As shown, the first smoke-blocking assembly 600 includes a first upper smoke-blocking plate 611, a second upper smoke-blocking plate 612, and a first driving device 620. The first upper smoke-blocking plate 611 and the second upper smoke-blocking plate 612 are rotatable and are used to open and close different parts of the first smoke-inlet 112. The first driving device 620 is used to drive one of the first upper smoke-blocking plate 611 and the second upper smoke-blocking plate 612 to rotate, and through it, drive the other of the first upper smoke-blocking plate 611 and the second upper smoke-blocking plate 612 to rotate, so that the first upper smoke-blocking plate 611 and the second upper smoke-blocking plate 612 can rotate synchronously to open or close different parts of the first smoke-inlet 112 synchronously.

[0155] For example, when a user does not use the range hood 1 for a long time and needs to close the first smoke inlet 112, the first upper smoke baffle 611 and the second upper smoke baffle 612 are connected end to end, such as... Figure 15 As shown, at this time, the projections of the first upper smoke baffle 611 and the second upper smoke baffle 612 toward the first smoke inlet 112 can completely cover the first smoke inlet 112, so that the first smoke inlet 112 can be completely closed with the cooperation of the first upper smoke baffle 611 and the second upper smoke baffle 612, preventing dust or other pollutants from entering the first smoke chamber 114 from the first smoke inlet 112 and causing pollution to the first smoke chamber 114. This can protect the components and environment inside the first smoke chamber 114 to a certain extent.

[0156] In addition, in some embodiments, when the first smoke baffle assembly 600 closes the first smoke inlet 112, it can prevent dirt in the upper smoke chamber from being exposed to the outside, and the lower surface of the first upper smoke baffle 611 can be flush with the lower surface of the second upper smoke baffle 612 and flush with the wall surface on the first main body 110 where the first smoke inlet 112 is formed, so as to improve the overall aesthetics of the range hood 1.

[0157] When the user needs to open the first smoke inlet 112, such as Figure 14As shown, the first driving device 620 can drive one of the first upper smoke baffle 611 and the second upper smoke baffle 612 to rotate. While the smoke baffle is rotating, it can simultaneously drive the other of the first upper smoke baffle 611 and the second upper smoke baffle 612 to rotate, so that a gap is made between the first upper smoke baffle 611 and the second upper smoke baffle 612. At this time, the first smoke baffle assembly 600 opens the first smoke inlet 112, and the oil fumes can enter the first smoke chamber 114 from the first smoke inlet 112.

[0158] In some embodiments, the rotation angle of the first upper smoke baffle 611 and the second upper smoke baffle 612 is adjustable. That is, the rotation angle of the first upper smoke baffle 611 and the second upper smoke baffle 612 can be different, and the degree to which the first smoke baffle assembly 600 opens the first smoke inlet 112 is also different, so as to meet the different needs of users.

[0159] In some embodiments of the present invention, the rotation axis of the first upper smoke baffle 611 and the rotation axis of the second upper smoke baffle 612 are respectively close to the two oppositely arranged edges of the first smoke inlet 112, so that the first upper smoke baffle 611 and the second upper smoke baffle 612 can completely close the first smoke inlet 112, and so that the first upper smoke baffle 611 and the second upper smoke baffle 612 only leave a gap after rotation to open the first smoke inlet 112, thereby preventing the oil fumes from spreading into the first smoke chamber 114.

[0160] like Figure 14 , Figure 15 As shown, in this embodiment, the first upper smoke baffle 611 and the second upper smoke baffle 612 are arranged at intervals along the width direction of the first smoke inlet 112. For example, the width direction of the first smoke inlet 112 extends in the front-rear direction. The first upper smoke baffle 611 can rotate about a rotation axis near the rear edge of the first smoke inlet 112. The second upper smoke baffle 612 can rotate about a rotation axis near the front edge of the first smoke inlet 112, thereby opening or closing the front part of the first smoke inlet 112.

[0161] When the first smoke-blocking assembly 600 closes the first smoke-absorbing port 112, such as Figure 15 As shown, at this time, the first upper smoke baffle 611 and the second upper smoke baffle 612 extend in the front-back direction. The rear end of the second upper smoke baffle 612 contacts and engages with the front end of the first upper smoke baffle 611. At this time, the first upper smoke baffle 611 blocks the rear part of the first smoke inlet 112, and the second upper smoke baffle 612 blocks the front part of the first smoke inlet 112. The first upper smoke baffle 611 and the second upper smoke baffle 612 cooperate with each other to close the first smoke inlet 112.

[0162] When the first smoke-blocking component 600 opens the first smoke inlet 112, such as Figure 14As shown, the first driving device 620 can drive the first upper smoke baffle 611 to rotate around the rear edge of the first smoke inlet 112. When the first upper smoke baffle 611 rotates, it can drive the second upper smoke baffle 612 to rotate around the front edge of the first smoke inlet 112, so that the front end of the first upper smoke baffle 611 and the rear end of the second upper smoke baffle 612 are separated, creating a gap to open the first smoke inlet 112.

[0163] In some embodiments of the present invention, such as Figure 14 , Figure 15 As shown, the first smoke-blocking assembly 600 also includes a smoke inlet grille 630. When the first smoke-blocking assembly 600 is in the state of opening the first smoke inlet 112, at least a portion of the smoke inlet grille 630 is located between the first upper smoke baffle 611 and the second upper smoke baffle 612, so that the first upper smoke baffle 611, the second upper smoke baffle 612 and the smoke inlet grille 630 define an upwardly recessed smoke-collecting cavity 640, so as to guide the oil fumes to flow to the smoke-collecting cavity 640 and enter the first smoke-collecting cavity 114 from the first smoke inlet 112. This arrangement helps to improve the smoke extraction efficiency of the range hood 1, so that the range hood 1 can more efficiently extract oil fumes from the first smoke inlet 112.

[0164] In some embodiments, the smoke inlet grille 630 is a metal grille. The metal grille itself has a low temperature, so that when the oil fumes enter the first smoke chamber 114 from the first smoke inlet 112, the oil fumes quickly condense and adhere to the metal grille, thereby achieving separation of oil and smoke, and facilitating oil collection. In addition, the smoke inlet grille 630 is designed to ensure that oil fumes can enter the first smoke chamber 114 from the first smoke inlet 112 while preventing debris such as plastic bags and cling film from being drawn into the first smoke chamber 114 from the first smoke inlet 112.

[0165] In some embodiments of the present invention, such as Figure 1 , Figure 5 and Figure 17 As shown, the range hood 1 also includes a second main body 120, which extends in the vertical direction. The upper end of the second main body 120 is connected to the rear end of the first main body 110. The second main body 120 defines a second smoke chamber 122. The second smoke chamber 122 has a front opening, which is formed as a second smoke inlet 121, so that the fumes generated near the stove can enter the second smoke chamber 122 from the second smoke inlet 121 and be discharged by the range hood 1.

[0166] In some embodiments, a fan 115 is provided inside the first main body 110. Driven by the fan 115, oil fumes can enter the range hood 1 from the first smoke inlet 112 or the second smoke inlet 121.

[0167] In some embodiments, the upper part of the first main body 110 is provided with a fume outlet 113, which is connected to the outside. Fume entering the second smoke chamber 122 from the second smoke inlet 121 is discharged vertically from the fume outlet 113 by the fan 115. Fume flowing into the first smoke chamber 114 from the first smoke inlet 112 is discharged vertically from the fume outlet 113 by the fan 115.

[0168] In some specific embodiments of the present invention, such as Figure 5 , Figure 17 As shown, the first smoke inlet 112 is located directly above the stove, and the second smoke inlet 121 is located slightly above the rear of the stove. During cooking, the fumes are drawn into the second smoke inlet 121 as soon as they are produced. Due to the negative pressure created by the fan 115 within the first main body 110, the fumes can enter the second smoke chamber 122 from the second smoke inlet 121. Driven by the fan 115, the fumes in the second smoke chamber 122 can flow horizontally towards the fan 115 and be discharged vertically from the smoke outlet 113, thereby achieving efficient smoke extraction.

[0169] After the second smoke inlet 121 sucks away most of the oil fumes, the remaining oil fumes will float upwards to the first smoke inlet 112 and enter the first smoke chamber 114 from the first smoke inlet 112. Driven by the fan 115, the oil fumes in the first smoke chamber 114 can flow horizontally to the fan 115 and be discharged vertically from the oil fume outlet 113.

[0170] In some alternative embodiments of the present invention, such as Figure 16 , Figure 17 As shown, the second main body 120 is provided with a second smoke baffle assembly 700. The second smoke baffle assembly 700 includes a lower smoke baffle 710 and a second driving device 720. The second driving device 720 is connected to the lower smoke baffle 710 and is used to drive the lower smoke baffle 710 to move, so that the lower smoke baffle 710 can move in the front and back direction to open or close the second smoke inlet 121 to meet the user's usage needs.

[0171] For example, when a user needs to open the second smoke inlet 121 and the range hood 1 needs to smoke through the second smoke inlet 121, the second drive device 720 can drive the lower smoke baffle 710 to move backward. At this time, the lower smoke baffle 710 opens the second smoke inlet 121, and the oil fumes can enter the second smoke inlet 121.

[0172] When the user does not need to open the second smoke inlet 121, the second drive device 720 can drive the lower smoke baffle 710 to move forward. At this time, the lower smoke baffle 710 closes the second smoke inlet 121 to prevent dust and other pollutants from entering the second smoke chamber 122 from the second smoke inlet 121 and causing pollution to the second smoke chamber 122. This setting can protect the components in the second smoke chamber 122 and the environment in the second smoke chamber 122 to a certain extent.

[0173] Among them, such as Figure 16 As shown, when the lower smoke baffle 710 closes the second smoke inlet 121, it can prevent dirt in the lower smoke chamber 122 from being exposed to the outside. The lower smoke baffle 710 can be flush with the wall surface on the second main body 120 where the second smoke inlet 121 is formed, so as to improve the overall aesthetics of the second main body 120 while closing the second smoke inlet 121.

[0174] In some alternative embodiments of the present invention, such as Figure 16 As shown, an oil collection container 820 is provided inside the second smoke chamber 122. The oil collection container 820 is located below the second smoke inlet 121. The oil collection container 820 defines an oil collection chamber 821 with its opening facing upwards. When oil fumes enter the second smoke chamber 122 from the second smoke inlet 121, some of the oil fumes will liquefy into oil when they encounter the cooler air inside the second smoke chamber 122. Since oil has a higher density, it will flow downwards and into the oil collection container 820 to prevent this part of the oil from polluting the environment inside the second smoke chamber 122.

[0175] In some embodiments, the oil collection container 820 is detachably disposed below the second smoke inlet 121, so that the user can clean or replace the oil collection container 820 in a timely manner when needed, and avoid the oil in the oil collection container 820 overflowing and polluting the environment inside the second smoke chamber 122.

[0176] In some examples, the oil collection container 820 includes a first oil collection section and a second oil collection section, which are detachably connected and can be axially symmetrical in structure, forming the oil collection container 820 through contact. For example, the first oil collection section is the left half of the oil collection container 820, and the second oil collection section is the right half. Due to the large size of the oil collection container 820, when the user needs to clean the oil collection container 820, the first and second oil collection sections can be disassembled and cleaned separately. This reduces the difficulty of cleaning and allows the first and second oil collection sections to be placed in a dishwasher or other equipment for machine cleaning.

[0177] In some optional embodiments of the present invention, such as Figure 17As shown, the oil collection container 820 has a first oil guiding part 824, which is located in front of the oil collection chamber 821. The first oil guiding part 824 extends downward from front to back to guide the flow of oil, so that the oil flows smoothly into the oil collection chamber 821 through the first oil guiding part 824, and avoids the oil flowing to other positions and causing pollution to the environment in the second smoke chamber 122.

[0178] In some embodiments, such as Figure 16 , Figure 17 As shown, the lower baffle 710 extends vertically. When the lower baffle 710 opens the second smoke inlet 121, it is located inside the second smoke chamber 122 and directly above the oil collection chamber 821. When fumes enter the second smoke chamber 122 from the second smoke inlet 121, some of the fumes will directly contact the lower baffle 710. When these fumes encounter the lower baffle 710, which has a lower temperature, they will liquefy into oil. The oil will flow downwards along the lower baffle 710 into the oil collection chamber 821, facilitating collection by the oil collection container 820 and preventing the oil from flowing to other locations and polluting the environment inside the second smoke chamber 122.

[0179] In some specific embodiments of the present invention, such as Figure 16 As shown, the oil collection container 820 includes an oil guide plate 822. One end of the oil guide plate 822 is provided with a limiting flange 823, which can be locked onto the lower edge of the second smoke port 121. The other end of the oil guide plate 822 extends toward the oil collection cavity 821. The upper surface of the oil guide plate 822 forms a first oil guiding part 824. On the one hand, the position of the oil collection container 820 can be fixed by the cooperation of the oil guide plate 822 and the limiting flange 823. On the other hand, the upper surface of the oil guide plate 822 can be used to guide the oil so that the oil can flow into the oil collection cavity 821.

[0180] like Figure 16 , Figure 17 As shown, in this embodiment, the front side of the oil guide plate 822 is provided with a limiting flange 823. The upper end of the limiting flange 823 protrudes from the upper surface of the oil guide plate 822, and the lower end of the limiting flange 823 protrudes from the lower surface of the oil guide plate 822. The limiting flange 823 extends out of the second smoke port 121 to be locked at the lower edge of the second smoke port 121, thereby stably fixing the oil collection container 820 in the second smoke chamber 122.

[0181] When the lower baffle 710 closes the second smoke inlet 121, the lower end of the lower baffle 710 engages with the limiting flange 823. The limiting flange 823 covers the gap between the lower end of the lower baffle 710 and the upper surface of the oil guide plate 822, preventing dust and other contaminants from entering the second smoke chamber 122 through the gap. This also helps maintain the overall aesthetics of the main body 100 of the range hood.

[0182] In some alternative embodiments of the present invention, such as Figure 16 , Figure 17 As shown, the second smoke chamber 122 is also provided with a second oil guiding part 830. The second oil guiding part 830 is located above the second smoke inlet 121 and extends downward from front to back. When the oil fumes drift to the top of the second smoke chamber 122 and liquefy into oil upon encountering cold air, the second oil guiding part 830 can guide the oil to flow smoothly into the oil collection chamber 821, thus preventing this part of the oil from polluting the environment inside the second smoke chamber 122.
