[0057] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0058] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0059] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0060] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0062] Nowadays, the kitchen island is becoming more and more popular. The kitchen island is an open kitchen, in which the kitchen island is usually located in the center or central area of ​​the kitchen. It is commonly rectangular, circular and L-shaped, and is often equipped with a stove, sink or food preparation area, which increases the working area of ​​the kitchen and facilitates multiple people to operate at the same time. It can be seen that the cooking utensils in the kitchen island are in an open space on all sides, not limited to the smaller activity space of the traditional kitchen, so that family members or friends can easily communicate when preparing food, enhancing the social function of the kitchen.

[0063] When cooking in the kitchen, the fumes generated during cooking will spread around the kitchen island, polluting the surrounding environment. However, the range hoods in the related art are relatively large in size, which will inevitably block the user's sight when used in the kitchen island cooking environment, occupy the user's activity space, and affect the user experience.

[0064] In view of this, the embodiment of the present application proposes an air curtain device. The air curtain device can be used alone or together with a matching cooking device to form a set of cooking equipment for use. The embodiment of the present application does not limit this. The following takes the application of the air curtain device to a kitchen island as an example for specific explanation. For the convenience of description, the kitchen island has a length direction XX, a width direction YY, and a height direction ZZ that are perpendicular to each other.

[0065] Please refer to Figures 1 to 3In some embodiments, the wind curtain device 100 includes an air duct shell 10, a fan 20 and an air guide structure 30. The air duct shell 10 defines an air duct 11 and an air inlet 12 and an air outlet 13 connected to the air duct 11. The fan 20 is disposed in the air duct 11 or at the air inlet 12, and the air guide structure 30 is disposed at the air outlet 13.

[0066] Specifically, the air duct shell 10 can be made of materials such as galvanized sheet, stainless steel sheet or aluminum alloy sheet, which has the advantages of being corrosion-resistant, not easy to rust, easy to clean and convenient to produce, and can be selected according to actual conditions. A continuous air duct 11 is formed inside the air duct shell 10 to connect the air inlet 12 and the air outlet 13. For the air inlet 12, the shape of the air inlet 12 can be circular, square, etc., and in some embodiments where the fan 20 is arranged at the air inlet 12, the shape of the air inlet 12 is adapted to the fan 20 to ensure the air intake effect. The air inlet 12 can be optionally arranged below the air duct shell 10 to facilitate the extraction of air and reduce the impact on the human body. The air outlet 13 is arranged in a long strip shape so that the air flow flowing out of the air outlet 13 can be unfolded to form a wind curtain and expand the coverage of the wind curtain.

[0067] The fan 20 can be selected as an axial flow fan 20, a cross flow fan 20 or a centrifugal fan 20, etc. It can be understood that when the fan 20 is a cross flow fan 20, it can be set in the air duct 11; when the fan 20 is a centrifugal fan 20 or an axial flow fan 20, it can be set at the air inlet 12 to ensure the air outlet effect.

[0068] It should be noted that the countertop of the kitchen island 1000 is provided with a avoidance opening corresponding to the air outlet 13. When the fan 20 is working, the air curtain device 100 enters the air outlet state, and the airflow flowing out of the air outlet 13 can flow out upward from the avoidance opening and form an air curtain. The air outlet 13 is arranged on at least one side of the cooking device 200. It can be understood that the airflow blown out of the air outlet 13 forms an air curtain, which can reduce the heat exchange between the kitchen island 1000 and the outside world, maintain a constant temperature, and improve energy efficiency. On the other hand, the air curtain can form a barrier separating the kitchen island 1000 from other spaces, effectively preventing dust, insects, etc. from entering the kitchen island 1000 space, and effectively reducing or preventing the smoke generated during the cooking process from escaping to other spaces outside the kitchen island 1000, avoiding the smoke from polluting the environment of other spaces.

[0069] The air curtain device 100 of the embodiment of the present application is further provided with an air guide structure 30, which is used to form an air curtain inclined toward the cooking device 200 by causing the air flow flowing out of the air outlet 13. The inclined air curtain can cover a relatively wide countertop of the kitchen island 1000, reduce dead angles, and gather the smoke generated by the cooking device 200 during the cooking process, and prevent the smoke from escaping to other spaces outside the kitchen island 1000.

[0070] Of course, in addition to being used in the kitchen island 1000, the air curtain device 100 can also be used in the cooking area of ​​a traditional kitchen and be arranged under the kitchen countertop so that the air outlet 13 blows air upward to form an air curtain inclined toward the cooking device 200, which is not limited in this embodiment of the present application.

[0071] Therefore, the air curtain device 100 proposed in the embodiment of the present application forms an air duct 11, an air inlet 12 and an air outlet 13 through the air duct shell 10. When the fan 20 is working, the airflow is blown upward from the air inlet 12 through the air duct 11 and the air outlet 13, and the air guide structure 30 forms an air curtain inclined toward the cooking device 200, which can not only effectively separate the kitchen space where the air curtain device 100 is located from other spaces, improve the heat utilization rate and gather smoke, effectively prevent smoke from escaping to other spaces, and avoid polluting other space environments, but also because the air curtain device 100 blows air upwards, when used in the kitchen, the air curtain device 100 is located below the kitchen countertop and does not occupy the space above the kitchen, thereby avoiding blocking the user's line of sight and improving the user experience.

[0072] The following explanation is still based on the example of the air curtain device 100 being applied to the kitchen island 1000.

[0073] Combination Figure 1 and Figure 2 In one embodiment, the air duct housing 10 includes a wind box 14 and an air guide section 15. The wind box 14 is in a flat box shape, which is conducive to accelerating the gas flow rate entering the air duct 11. An air inlet 12 is provided at the bottom of the wind box 14. For some structural forms in which the fan 20 is arranged at the air inlet 12, the fan 20 is connected to the wind box 14. The air guide section 15 is connected to at least one side of the wind box 14, thereby defining the air duct 11 together with the wind box 14. In the illustrated embodiment, the air guide section 15 extends along the height direction ZZ, and the air guide section 15 is in the shape of a long strip extending along the length direction XX or the width direction YY, so as to construct a long strip of air guide, which is used to guide the airflow in the wind box 14 from the air outlet 13 to form a wind curtain.

[0074] Optionally, the air guide section 15 and the wind box 14 can be made of the same or different materials, and can be an integral structure or connected by welding after being separately formed. When the air guide section 15 and the wind box 14 are an integral structure, they can be integrally cast, which has good structural integrity and high production efficiency. The overall structure of the air curtain assembly is simple, which saves space and is easy to install.

[0075] exist Figure 2 In the illustrated embodiment, the fan 20 is an axial flow fan 20, and the fan 20 is connected to the wind box 14 and is arranged at the air inlet 12. When the fan 20 is working, the air flow enters the fan 20 at the air inlet 12, and the structure is simple and can be uniformly controlled.

[0076] Reference Figure 3 In another embodiment, the air duct shell 10 can also be directly constructed into a tubular structure, and the fan 20 is a cross-flow fan 20, and is arranged in the air duct 11; thus, in a structural embodiment with multiple air outlets 13, multiple air ducts 11 can be formed by multiple air duct shells 10, and a cross-flow fan 20 is arranged in each air duct 11, so that the multiple cross-flow fans 20 can be controlled separately, which is more flexible.

[0077] Please refer to Figure 4 In one embodiment, the air guide section 15 is arranged to be inclined toward the cooking device 200. In this embodiment, taking the air guide section 15 extending along the length direction XX as an example, the inner wall surfaces on both sides of the air guide section 15 along the length direction XX are respectively the front wall close to the cooking device 200 and the rear wall away from the cooking device 200, and both the front wall and the rear wall are inclined toward the cooking device 200 relative to the height direction ZZ. In this way, the airflow passing through the air guide section 15 flows out under the guidance of the inclined air guide section 15, so that an air curtain inclined toward the cooking device 200 can be formed. In this embodiment, the airflow is guided by setting the inclined air guide section 15, and the structure is simple and effective.

[0078] Please refer to Figure 5 In another embodiment, the air guide structure 30 includes a plurality of first air guide plates 31 connected to the air duct housing 10. Still taking the air guide section 15 extending along the length direction XX as an example, the width direction of the air guide section 15 (air outlet 13) is also the width direction YY, and a plurality of first air guide plates 31 are arranged at intervals in the width direction XX and extend along the extension direction (length direction XX) of the air outlet 13. The first air guide plate 31 is arranged at one end of the air duct 11 close to the air outlet 13, so as to guide the airflow at the air outlet 13. Specifically, the first air guide plate 31 is configured to be inclined toward the cooking device 200 relative to the height direction ZZ, so as to guide the airflow flowing out of the air outlet 13 to be inclined toward the cooking device 200. By providing the first air guide plate 31, this embodiment not only guides the airflow, so that the airflow flowing out of the air outlet 13 forms a wind curtain inclined toward the cooking device 200, but also improves the flow state of the airflow, makes the airflow of the wind curtain more uniform, and ensures the stability and continuity of the wind curtain.

[0079] It can be understood that the air curtain device 100 has an outlet state and a standby state. In the outlet state, the fan 20 works, and the airflow flowing out of the air outlet 13 forms an air curtain to prevent smoke from escaping to the outside space; in the standby state, the fan 20 does not work, and the air outlet 13 does not flow out to form an air curtain. The user can selectively switch between the above two use states according to the actual use conditions. In the standby state, the open air outlet 13 easily allows foreign objects such as dust to fall into the air duct 11, affecting the operation of the fan 20, and easily blocking the air duct 11, affecting the user.

[0080] Please refer to Figure 6 In one embodiment, the air guide structure 30 further includes a wind shield 33, which is disposed at the air outlet 13 and outside the air duct 11, and is connected to the air duct housing 10. In the standby state, the wind shield 33 covers the air outlet 13, and in the air outlet state, the wind shield 33 is spaced apart from the air outlet 13 so that air flows out from the air outlet 13. In this way, in the standby state, the wind shield 33 can shield the air outlet 13, which can not only prevent foreign matter from entering the air duct 11 and affecting the normal use of the air curtain device 100, improve the reliability of the air curtain device 100, but also make the kitchen countertop more integrated and more beautiful.

[0081] Furthermore, the windshield 33 is disposed on a side of the air outlet 13 away from the cooking device 200, and is movably connected to the air duct shell 10. Exemplarily, the windshield 33 is rotatably connected to the air duct shell 10, and the standby state and the air outlet state are switched by rotating the windshield 33. Optionally, the wind curtain device 100 also includes a driving member connected to the windshield 33, and the driving member can be a motor. The windshield 33 is connected to the output end of the driving member, and the driving member is used to drive the windshield 33 to rotate relative to the air duct shell 10, thereby realizing state switching. Of course, the wind curtain device 100 also includes a limiting member connected to the windshield 33, and the user can manually rotate the windshield 33, and when it is rotated to a certain extent, the position of the windshield 33 is limited by the limiting member, for example, the limiting member and the windshield 33 can be connected by magnetic attraction, snap-on, etc.

[0082] Among them, in the air outlet state, the wind shield 33 is tilted toward the cooking device 200, and the airflow flowing out of the air outlet 13 forms a wind curtain tilted toward the cooking device 200 under the guidance of the wind shield 33. That is to say, the wind shield 33 of the present application not only covers the air outlet 13 in the standby state to improve the reliability and aesthetics of the wind curtain device 100, but also can guide the airflow at the air outlet 13 in the air outlet state.

[0083] Of course, the above-mentioned methods of guiding the airflow by using the inclined air guide section 15, the first air guide plate 31 and the wind shield plate 33 can be combined arbitrarily. For example, in one embodiment, the air curtain device 100 can simultaneously tilt the air guide section 15, and set the first air guide plate 31 in the air guide section 15, and connect the wind shield plate 33 at the air outlet 13, which can enhance the guiding effect of the airflow in the air outlet state, so that the smoke blocking effect of the air curtain is better, and foreign matter can be prevented from entering the air duct 11 in the standby state, thereby improving the reliability and aesthetics of the air curtain device 100.

[0084] Another aspect of the embodiment of the present application provides a cooking device, which includes a cooking device 200 and the air curtain device 100 as described above. The cooking device 200 may be an induction cooker or a gas stove, etc. The air outlet 13 is provided on at least one side of the cooking device 200 to prevent the fumes generated during cooking from escaping to other spaces.

[0085] Combination Figure 7 and Figure 8 In one embodiment, the cooking device is applied to the kitchen island 1000, and the air outlet 13 includes an enclosure air outlet 131 for being set on the island of the kitchen island 1000 and located at the periphery of the cooking device 200. It can be understood that a avoidance opening corresponding to the enclosure air outlet 131 is provided on the kitchen island 1000, so that the air flow out of the enclosure air outlet 131 can pass through the avoidance opening to form an air curtain. The enclosure air outlet 131 in this embodiment is set outside the cooking device 200, and there is a certain distance between it and the cooking device 200. The air outlet direction of the enclosure air outlet 131 is set at an angle α1 with the height direction (height direction ZZ) of the cooking device 200, where 0°<α1≤30°.

[0086] It can be understood that if α1 is greater than 30°, it means that the wind curtain has a larger inclination angle, which can easily cause the airflow forming the wind curtain to blow to the opposite side of the center island 1000, causing discomfort to the user on the opposite side. On the other hand, the larger inclination angle also reduces the gap between the wind curtain and the cooking device 200, and the height range of smoke that can be blocked by the wind curtain is reduced, which can easily cause smoke to bypass the wind curtain and escape to other spaces, affecting the user experience. Therefore, this embodiment limits 0°<α1≤30° to avoid the wind curtain causing user discomfort and ensure the effect of the wind curtain in blocking smoke. α1 can be selected as 10°, 15°, 30°, etc.

[0087] Combination Fig. 9 and Fig.10 In another embodiment, the air curtain device 100 is integrated with the cooking device 200. Specifically, the cooking device 200 includes a cooking panel 210 and a cooking utensil 230 disposed on the cooking panel 210. The cooking utensil 230 may be a partial structure of a gas stove or an induction cooker for forming a heating area. In this embodiment, the air outlet 13 includes an enclosure air outlet 131 disposed on the cooking panel 210 and located at the periphery of the cooking utensil 230. The air outlet direction of the enclosure air outlet 131 is inclined toward the cooking utensil 230 to form an air curtain inclined toward the cooking utensil 230, and the enclosure air outlet 131 is arranged at an angle α2 with the height direction of the cooking device 200, where 0°<α2≤20°.

[0088] It can be understood that compared with the distance between the enclosure vent 131 and the cooking device 200 in the previous embodiment, the distance between the enclosure vent 131 and the cooking utensil 230 in this embodiment is smaller. Therefore, if α2 is greater than 20°, it means that the wind curtain has a larger inclination angle, which can easily cause the airflow forming the wind curtain to blow to the opposite side of the cooking utensil 230, causing discomfort to the user on the opposite side; on the other hand, the larger inclination angle also makes the gap between the wind curtain and the cooking utensil 230 smaller, and the height range of the smoke that the wind curtain can block is reduced, which can easily cause the smoke to bypass the wind curtain and escape to other spaces, affecting the user experience. Therefore, this embodiment limits 0°<α2≤20° to avoid the wind curtain causing user discomfort and ensure the effect of the wind curtain in blocking smoke. α2 can be selected as 10°, 15°, 18°, etc.

[0089] Combination Figure 7 and Fig. 9 , the enclosure vent 131 includes a first vent 1311 and at least one second vent 1313. The first vent 1311 is used to be arranged on the opposite side of the cooking side 240, and is extended along the first direction. When the cooking equipment is used in the center island 1000, one side of the center island 1000 is the cooking side 240, and on the contrary, the other side of the center island 1000 is usually a living room or a dining room, etc. The first vent 1311 can effectively prevent the smoke generated by cooking from escaping in the direction of the living room or the dining room, ensuring that the environment of the living room or the dining room is clean and tidy. It can be understood that the first direction can be the length direction XX, and along the first direction, the length of the first vent 1311 is greater than or equal to the length of the cooking utensil 230, so as to effectively block the oil smoke.

[0090] The second air outlet 1313 is located at least on one side of the first air outlet 1311 along the first direction, and is extended along a second direction that is angled with the first direction. Optionally, the second length may be in the width direction YY. The second air outlet 1313 is disposed on at least one side of the cooking device 200 along the width direction YY. In the air outlet state, the second air outlet 1313 can block the escape of smoke to the side of the center island 1000, and the second air outlet 1313 and the first air outlet 1311 are arranged in a circumferential interval around the cooking device 200, so as to more comprehensively block the outflow of oil smoke.

[0091] Combination Figure 7 and Fig. 9 , the length of the first air outlet 1311 along the first direction is L1, and the length of the second air outlet 1313 along the second direction is L2, satisfying the relationship L1≥L2. In this embodiment, the first air outlet 1311 is arranged on the opposite side of the cooking side 240, and the wind curtain formed by the first air outlet 1311 is located between the center island 1000 and the dining room or living room, so that the first air outlet 1311 has a longer length, which can effectively prevent the smoke from cooking on the center island 1000 from escaping to the dining room or living room, thereby reducing environmental pollution in the dining room or living room.

[0092] Furthermore, the air volume of the first air outlet 1311 is F1, and the air volume of the second air outlet 1313 is F2, which satisfies the relationship F1≥1.5F2. In other words, the air volume of the first air outlet 1311 is larger than that of the second air outlet 1313. Since the smoke mainly escapes toward the space on the other side of the first air outlet 1311 (dining room or living room), increasing the air volume of the first air outlet 1311 can make the wind curtain formed by the airflow flowing out of the first air outlet 1311 better block the smoke.

[0093] In one embodiment, the air outlet 13 further includes a cooking side air outlet 133 located on the cooking side 240, which is used to block the smoke generated by cooking from flowing out of the cooking side 240. For example, the cooking side air outlet 133 is used to be set on the island of the kitchen island 1000, and the air outlet direction of the cooking side air outlet 133 is set at an angle β1 with the height direction of the cooking device 200, wherein 0°<β1≤25°. It can be understood that if β1 is greater than 25°, the wind curtain has a larger inclination angle, which is easy to make the wind curtain airflow formed on the cooking side 240 cause discomfort to the user on the opposite side. On the other hand, the larger inclination angle also reduces the height range of smoke that can be blocked by the wind curtain, which is easy to cause smoke to bypass the wind curtain and escape to the outside of the cooking side 240, affecting the user experience. Therefore, this embodiment limits 0°<β1≤30° to avoid the wind curtain causing discomfort to the user and ensure the effect of the wind curtain in blocking smoke. α1 can be selected as 10°, 15°, 25°, etc.

[0094] For another example, the cooking side vent 133 can also be set on the cooking panel 210, and the air outlet direction of the cooking side vent 133 is inclined toward the cooking utensil 230, and is set at an angle β2 with the height direction of the cooking device 200, wherein 0°<β2≤15°. Compared with the previous embodiment in which the cooking side vent 133 is set on the island 1000, the distance between the cooking side vent 133 and the cooking utensil 230 in this embodiment is smaller. Therefore, if β2 is greater than 15°, it is easy for the airflow forming the wind curtain to blow to the opposite side of the cooking utensil 230, causing discomfort to the user on the opposite side; on the other hand, a larger inclination angle also reduces the height range of smoke that can be blocked by the wind curtain, which easily causes smoke to bypass the wind curtain and escape to other spaces, affecting the user experience. Therefore, this embodiment limits 0°<β2≤15° to avoid the wind curtain causing user discomfort and ensure the effect of the wind curtain in blocking smoke. β2 can be selected as 10°, 15°, etc.

[0095] In combination with the above embodiments, relative to the height direction of the cooking device 200, the inclination angle of the air outlet 13 close to the cooking device 200 is less than or equal to the inclination angle of the air outlet 13 away from the cooking device 200. By adjusting the inclination angle of the air outlet direction of the air outlet 13, the effect of the wind curtain blocking smoke is ensured while avoiding causing discomfort to the user, thereby improving the user experience.

[0096] The cooking device 200 includes at least one cooking utensil 230 disposed on a cooking panel 210. It is understandable that the smoke is more concentrated where the cooking utensil 230 is located. Figure 7 , Fig. 9 as well as Fig.11 and Fig.12 In one embodiment, the air guide structure 30 further includes a plurality of second air guide plates 32, which are arranged at one end of the air duct 11 close to the air outlet 13 and are extended in a direction that is angled with the extension path of the air outlet 13. For example, for the air outlet 13 extending in the length direction XX, the second air guide plates 32 are extended in the width direction YY. The air outlet 13 has a smoke blocking section that is opposite to the cooking utensil 230 along the length direction or the width direction of the cooking panel 210. For example, the length direction and the width direction of the cooking panel 210 are respectively along the length direction XX and the width direction YY. For the first air outlet 1311, the first air outlet 1311 extends in the length direction XX and has a smoke blocking section that is opposite to the cooking utensil 230 along the width direction YY. The smoke blocking section is closer to the cooking utensil 230 than other parts of the first air outlet 1311. It can be understood that the smoke blocking section has more smoke and is more concentrated because it is opposite to the cooking utensil 230.

[0097] Optionally, at least part of the second air guide plate 32 is inclined toward the smoke blocking section along the extension direction of the air outlet 13. Fig.11 As shown, the second air guide plates 32 are radially arranged to increase the amount of air flowing out of the smoke blocking section, thereby more effectively blocking the smoke.

[0098] Or, if Fig.12 As shown, the distance between two connected second air guide plates 32 in the extension direction of the air outlet 13 can gradually increase in the direction approaching the smoke blocking section, which can also increase the air volume flowing out of the smoke blocking section and improve the smoke blocking effect.

[0099] It can be understood that in some embodiments, the air guide structure 30 includes both the first air guide plate 31 and the second air guide plate 32. The first air guide plate 31 and the second air guide plate 32 can be arranged at intervals, or the first air guide plate 31 and the second air guide plate 32 can also be connected to form an air guide grille. Further, the first air guide plate 31 and the second air guide plate 32 can be integrally formed with the air duct housing 10, so as to facilitate processing, improve production efficiency and structural integrity.
