The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] The current functional component experience is poor, for example, the embedded functional component is generally placed below the table top, so that, on the one hand, the lower cabinet space is occupied, on the other hand, the functional disc is placed by bending down, the inner container is cleaned by squatting down, and the steam hits the face when the door is opened, so that the user experience is poor.

[0030] Please refer to Figures 1-6, in order to solve the problem of poor user experience of the existing functional components, the present application provides a full-embedded integrated structure, which comprises a fan assembly 1000, a first lifting mechanism, a functional component, an air inlet plate group 2000 and a second lifting mechanism.

[0031] It should be noted that the functional component includes but is not limited to a steaming and baking component, an air-frying module component, a dishwashing module component, etc., which are not listed here.

[0032] Further, it should be noted that the fan assembly 1000 and the air inlet plate group 2000 are part of the range hood, the fan assembly 1000 is used to generate suction, and the external oil fume and steam are transported to the fan assembly 1000 through the air inlet plate group 2000. The functional component is mainly used for steaming or baking objects, and it is worth noting that the object will generate steam during steaming and smoke during baking, so the steam and smoke generated by the functional component during use also need to be discharged to the outside (kitchen external space) through the fan assembly 1000 and the air inlet plate group 2000.

[0033] As shown in Figure 1 and Figure 2 , the functional component, the air inlet plate group 2000 and the second lifting mechanism are connected to the fan assembly 1000 through the first lifting mechanism respectively, and the first lifting mechanism can drive the functional component, the air inlet plate group 2000 and the second lifting mechanism to move synchronously towards the direction of approaching or away from the fan assembly 1000.

[0034] The air inlet plate group 2000 is connected to the functional component through the second lifting mechanism, and the second lifting mechanism can drive the air inlet plate group 2000 to move towards the direction of approaching or away from the functional component.

[0035] During use, the fan assembly 1000 is arranged above, and the functional component is arranged below. When the functional component starts to work, the first lifting mechanism can drive the functional component to descend a predetermined height away from the fan assembly 1000, so as to facilitate the use of the functional component. When the functional component or other positions (such as gas stove and pot 7300, etc.) in the kitchen produce oil fume and steam, the second lifting mechanism can drive the air inlet plate group 2000 to descend a predetermined height away from the fan assembly 1000, so as to facilitate the suction of oil fume and steam.

[0036] It should be noted that the first lifting mechanism and the second lifting mechanism are independently operated, that is, the second lifting mechanism can directly drive the air inlet plate group 2000 to descend alone in the case that the first lifting mechanism drives the undriven functional assembly and the air inlet plate group 2000 and the second lifting mechanism as a whole to descend. Of course, the second lifting mechanism can continue to drive the air inlet plate group 2000 to descend in the case that the first lifting mechanism drives the functional assembly, the air inlet plate group 2000 and the second lifting mechanism as a whole to descend. Obviously, at this time, the position of the air inlet plate group 2000 is lower, which is more conducive to the suction of oil fume at a lower position.

[0037] As can be seen from the above, since the functional assembly and the range hood are integrally arranged, and the functional assembly is arranged above the countertop, in the full-embedded integrated structure provided in the present application, the functional assembly does not need to occupy the space of the lower cabinet 7200, and does not need to be bent to clean, and the steam can be effectively prevented from being puffed by the functional assembly by the fan assembly 1000 and the air inlet plate group 2000.

[0038] Further, the functional assembly and the range hood can be fully embedded in the upper cabinet 7100, so that the countertop of the kitchen is more simple and beautiful, and does not occupy too much countertop space.

[0039] In an embodiment, the air inlet plate group 2000 is mainly formed by a plurality of plates to form a structure with one side smoke suction port, so as to improve the smoke suction efficiency of the air inlet plate group 2000.

[0040] In an embodiment, as shown in Figures 2-4 The functional assembly includes a functional box 6200 and a partition frame 6100, wherein the functional box 6200 is used to realize the steaming function and the baking function of the functional assembly. The partition frame 6100 is provided with a containing cavity 6110, the functional box 6200 is installed at one end of the containing cavity 6110, and the second lifting mechanism is installed at the other end of the containing cavity 6110.

[0041] It should be noted that the functional box 6200 includes but is not limited to a steaming oven, an air fryer and a dishwasher, etc., which are not listed one by one here.

[0042] Specifically, in order to use conveniently, in an embodiment, the functional box 6200 is installed at the front end of the partition frame 6100, and it should be noted that the front end of the partition frame 6100 is close to the cabinet door of the upper cabinet 7100. The second lifting mechanism is installed at the rear end of the partition frame 6100, and it should be noted that the rear end of the partition frame 6100 is close to the wall surface.

[0043] But not limited to this, in other embodiments, the functional box 6200 and the second lifting mechanism can also be installed at the left and right ends of the partition frame 6100.

[0044] Further, as shown in Figures 2-4As shown, the second lifting mechanism can drive the air inlet plate set 2000 to extend out of the accommodating cavity 6110 towards the direction away from the fan assembly 1000, or, as shown, Figure 1 As shown, the second lifting mechanism can drive the air inlet plate set 2000 to retract into the accommodating cavity 6110 towards the direction close to the fan assembly 1000.

[0045] By arranging the partition frame 6100, the functional box 6200 and the air inlet plate set 2000 can be arranged in the accommodating cavity 6110, which greatly improves the assembly compactness of the full-embedded integrated structure, so that the volume of the full-embedded integrated structure in the closed state is greatly reduced, at this time, the entire full-embedded integrated structure can be accommodated in the upper cabinet 7100, which to some extent increases the aesthetic appearance of the entire kitchen decoration.

[0046] Further, in an embodiment, as shown, Figures 2-4 As shown, the second lifting mechanism is arranged on the side of the functional box 6200 away from the opening thereof, that is, the second lifting mechanism is arranged on the back of the functional box 6200.

[0047] In this way, the opening of the air inlet plate set 2000 and the functional box 6200 can be arranged at intervals, so as to avoid the oil fume and steam in the air inlet plate set 2000 directly entering the interior of the functional box 6200 through the opening of the functional box 6200.

[0048] Further, in an embodiment, as shown, Figures 2-4 As shown, the side wall of the partition frame 6100 is provided with a first assembly opening 6120 communicating with the accommodating cavity 6110, the functional box 6200 can be installed in the accommodating cavity 6110 from the first assembly opening 6120, and the opening of the functional box 6200 is arranged in the same direction as the first assembly opening 6120, so as to facilitate opening or closing the functional box 6200 through the first assembly opening 6120.

[0049] Specifically, the partition frame 6100 is in the shape of a cuboid, and one side end face of the cuboid-shaped partition frame 6100 is not provided with a shell to form the first assembly opening 6120, so as to reduce the processing difficulty of the first assembly opening 6120.

[0050] In an embodiment, the top wall of the partition frame 6100 is provided with a first air inlet opening communicating with the accommodating cavity 6110 and the fan assembly 1000, the functional box 6200 and the side wall of the partition frame 6100 away from the first assembly opening 6120 are arranged at intervals to form an air inlet channel, when the air inlet plate set 2000 is in the closed state, the air inlet plate set 2000 can be accommodated in the air inlet channel, when the air inlet plate set 2000 is in the open state, the air inlet plate set 2000 can sequentially pass through the air inlet channel and the first air inlet opening to communicate with the fan assembly 1000.

[0051] The air inlet channel is formed by the functional box 6200 and the side wall of the partition frame 6100 away from the first assembly opening 6120. On the one hand, the air inlet channel is formed in the containing cavity 6110 to pass through the oil fume and the steam, so that the oil fume and the steam are prevented from escaping everywhere, and the interference between the air inlet plate set 2000 and the functional box 6200 during use is avoided. On the other hand, a separate partition plate does not need to be arranged in the containing cavity 6110, so that the material is saved, and the weight and the cost are reduced.

[0052] Further, since the air inlet plate set 2000 can be accommodated (shrunk) in the air inlet channel in the closed state, the space utilization of the containing cavity 6110 is effectively improved.

[0053] It should be noted that in the embodiment, the second lifting mechanism is mounted on the side wall of the partition frame 6100 away from the first assembly opening 6120, that is, the second lifting mechanism is mounted on the rear wall of the partition frame 6100.

[0054] But not limited to this, in other embodiments, the second lifting mechanism can also be mounted on the left and right side walls of the containing cavity 6110,

[0055] In an embodiment, as shown in Figures 3-4 The fully embedded integrated structure further includes a relay frame 5000. The fan assembly 1000 is connected to the relay frame 5000 through the first lifting mechanism, and the functional assembly, the air inlet plate set 2000 and the second lifting mechanism are respectively mounted on one end of the relay frame 5000 away from the fan assembly 1000, so that the first lifting mechanism can drive the functional assembly, the air inlet plate set 2000 and the second lifting mechanism to move synchronously towards or away from the fan assembly 1000 through the relay frame 5000.

[0056] In this way, the relay frame 5000 is beneficial to the integrated assembly of the functional assembly, the air inlet plate set 2000 and the second lifting mechanism, and the assembly difficulty of the functional assembly, the air inlet plate set 2000 and the second lifting mechanism is reduced.

[0057] But not limited to this, in other embodiments, the functional assembly, the air inlet plate set 2000 and the second lifting mechanism can also be directly mounted on the first lifting mechanism.

[0058] Further, in an embodiment, as shown in Figure 4 The relay frame 5000 is provided with a nested cavity 5100, and when the first lifting mechanism drives the relay frame 5000 to move towards the fan assembly 1000, the relay frame 5000 can be sleeved on the outside of the fan assembly 1000 through the nested cavity 5100.

[0059] In this way, the volume of the fully embedded integrated structure is further reduced, and the fully embedded integrated structure is beneficial to be accommodated in the upper cabinet 7100.

[0060] Further, in an embodiment, the adapter frame 5000 is further provided with a second air inlet communicating with the first air inlet and the nested cavity 5100, so that the air inlet panel set 2000, the air inlet channel, the first air inlet, the second air inlet, the nested cavity 5100 and the fan assembly 1000 are sequentially communicated, so as to facilitate the oil fume and steam to finally enter the fan assembly 1000.

[0061] Specifically, in an embodiment, as shown in Figures 2-4 the adapter frame 5000 is in the shape of a cuboid, and the upper portion of the adapter frame 5000 is provided with a second assembly opening 5200 communicating with the nested cavity 5100, and the adapter frame 5000 can be sleeved on the outer side of the fan assembly 1000 through the second assembly opening 5200.

[0062] Further, the second air inlet is arranged at one end of the adapter frame 5000 away from the second assembly opening 5200.

[0065] Specifically, as shown in Figure 4 the back portion (the side away from the first assembly opening 6120) of the fan assembly 1000 is provided with a groove 1100 for accommodating the lead screw 3200. The inner wall of the adapter frame 5000 is fixedly provided with a connecting block (not shown), and the lead screw 3200 and the connecting block are threadedly connected.

Moreover, the first sliding block 3400 and the first guide rail 3300 are in sliding fit, so as to enable the adapter frame 5000 to move along a predetermined track relative to the fan assembly 1000 and improve the moving stability of the adapter frame 5000.

[0067] Further, in an embodiment, the number of the first guide rail 3300 and the first sliding block 3400 is multiple, and the multiple first guide rails 3300 and the first sliding blocks 3400 are distributed around the circumference of the fan assembly 1000.

[0068] In an embodiment, as shown in Figures 3-4 As shown, the second lifting mechanism comprises a second motor 4100, a worm (not shown), a worm wheel (not shown), a driving shaft 4200 and a pin 4300, the worm is connected to the output end of the second motor 4100, and the worm and the worm wheel are in meshing connection. The second motor 4100 is mounted on one of the partition frame 6100 and the air inlet plate set 2000, one end of the driving shaft 4200 is coaxially arranged and fixedly assembled with the worm, and the other end is clamped to the other one of the partition frame 6100 and the air inlet plate set 2000 through the pin 4300, so that the second motor 4100 can drive the air inlet plate set 2000 to move towards or away from the partition frame 6100 through the worm wheel, the worm, the driving shaft 4200 and the pin 4300 in sequence.

[0069] Specifically, the pin 4300 is arranged through the driving shaft 4200, and the two ends of the pin 4300 are respectively arranged in the air inlet plate set 2000.

[0070] Further, in an embodiment, as shown in Figures 3-4 As shown, the second lifting mechanism further comprises a second guide rail 4400 and a second sliding block, the second guide rail 4400 is mounted on one of the partition frame 6100 and the air inlet plate set 2000, and the second sliding block is mounted on the other one of the partition frame 6100 and the air inlet plate set 2000. Moreover, the second sliding block and the second guide rail 4400 are in sliding fit, so as to enable the air inlet plate set 2000 to move along a predetermined track relative to the partition frame 6100 and improve the moving stability of the air inlet plate set 2000.

[0071] Further, in an embodiment, the number of the second guide rail 4400 and the second sliding block is multiple, and the multiple second guide rails 4400 and the second sliding blocks are distributed around the circumference of the air inlet plate set 2000.

[0072] In an embodiment, as shown in Figures 2-6As shown, the function box 6200 comprises a main box body 6210, a door body 6220, a connecting rod mechanism and a resilient member 6230. The main box body 6210 is provided with a function cavity 6211 and a communication port 6212 communicating with the function cavity 6211. The object to be cooked is placed in the function cavity 6211 through the communication port 6212 or taken out of the function cavity 6211 through the communication port 6212.

[0073] The door body 6220 can be sealingly arranged at the communication port 6212 to keep the function box 6200 in a closed state during use. The connecting rod mechanism is hingedly connected to the main box body 6210 at one end and hingedly connected to the door body 6220 at the other end, so that the door body 6220 can be arranged in relative rotation with the main box body 6210 to open or close the communication port 6212.

[0074] The resilient member 6230 is connected to the main box body 6210 at one end and connected to the connecting rod mechanism at the other end, and can exert an elastic tension on the connecting rod mechanism.

[0075] It should be noted that the main box body 6210 comprises an inner container 6213 and an outer shell 6214, the outer shell 6214 being wrapped outside the inner container 6213. The connecting rod mechanism and the resilient member 6230 are connected to the outer shell 6214 of the main box body 6210, and the function cavity 6211 and the communication port 6212 are arranged in the inner container 6213.

[0076] In this way, on the one hand, when the door body 6220 is arranged on the main box body 6210, the resilient member 6230 can tension the connecting rod mechanism, so that the connecting rod mechanism drives the door body 6220 to close the main box body 6210, thereby improving the sealing performance of the communication port 6212 of the main box body 6210. On the other hand, when it is necessary to close the door body 6220, the resilient member 6230 can pull the door body 6220 towards the main box body 6210, so that the door body 6220 is closed more easily, thereby improving the use experience of the function box 6200.

[0078] The compression spring structure is simple and easy to install, which is conducive to reducing the manufacturing cost of the function box 6200.

[0079] However, it is not limited thereto, and in another embodiment, the resilient member 6230 can also be an elastic rope, specifically, the elastic rope can be a latex member, a rubber member, a polyethylene member or a nylon member, etc., which are not listed one by one here.

[0080] In an embodiment, as shown in Figures 5-6As shown, the linkage mechanism includes a first link 6240 and a second link 6250. One end of the first link 6240 is hinged to the main housing 6210 via a first hinge shaft 6241, and the other end is hinged to the door 6220 via a second hinge shaft 6242. Similarly, one end of the second link 6250 is hinged to the main housing 6210 via a third hinge shaft 6251, and the other end is hinged to the door 6220 via a fourth hinge shaft 6252. Furthermore, the first hinge shaft 6241, the second hinge shaft 6242, the fourth hinge shaft 6252, and the third hinge shaft 6251 are arranged sequentially at the four vertices of the quadrilateral structure.

[0081] It should be noted that the first hinge axis 6241 and the second hinge axis 6242 are defined to form the first connecting line, and the third hinge axis 6251 and the fourth hinge axis 6252 are defined to form the second connecting line. Since the first hinge axis 6241, the second hinge axis 6242, the fourth hinge axis 6252 and the third hinge axis 6251 are arranged sequentially at the four vertices of the quadrilateral structure, the first connecting line and the second connecting line do not intersect. This is beneficial for the linkage structure to drive the door body 6220 to rotate over a wide range.

[0082] Furthermore, one end of the elastic element 6230 is connected to the first connecting rod 6240, and the other end is connected to the main housing 6210.

[0083] Thus, in the linkage mechanism, the first link 6240 is the driving member and the second link 6250 is the driven member. Compared with the scheme where both the first link 6240 and the second link 6250 are driving members, this scheme is obviously beneficial in avoiding the situation where the force directions of the first link 6240 and the second link 6250 are inconsistent, which would affect the rotation of the door 6220.

[0084] Furthermore, in one embodiment, as Figure 5 As shown, the distance A between the first hinge shaft 6241 and the second hinge shaft 6242, the distance B between the third hinge shaft 6251 and the fourth hinge shaft 6252, the vertical distance C between the first hinge shaft 6241 and the door body 6220, and the vertical distance D between the third hinge shaft 6251 and the door body 6220 when the door body 6220 is sealed and covered by the connecting port 6212, satisfy A>C and B>D.

[0085] With this configuration, when the linkage mechanism drives the door 6220 to open the communication port 6212, since A>C and B>D, the distance between the door 6220 and the main housing 6210 increases during rotation, which can effectively prevent the door 6220 from hitting the edge of the main housing 6210 during rotation.

[0086] But not limited to, in other embodiments, when the edge where the main box body 6210 and the door body 6220 are connected is in a circular arc shape, then A can be equal to C, and B can be equal to D, at this time, the door body 6220 will not knock against the main box body 6210 during rotation.

[0087] Further, in an embodiment, the vertical height of the first hinge shaft 6241 is greater than the vertical height of the third hinge shaft 6251, and A > B, so that the door body 6220 can be rotated to the bottom of the main box body 6210.

[0088] It should be noted that the bottom of the main box body 6210 is the side of the main box body 6210 away from the fan assembly 1000, and since the vertical height of the first hinge shaft 6241 is greater than the vertical height of the third hinge shaft 6251, and because the first hinge shaft 6241, the second hinge shaft 6242, the fourth hinge shaft 6252, and the third hinge shaft 6251 are arranged in order at the four vertices of the quadrilateral structure, that is, the first connecting line and the second connecting line do not intersect, and thus the first connecting rod 6240 is obviously arranged above the second connecting rod 6250. Therefore, when A > B, the first connecting rod 6240 can obviously extend a longer distance, which is more conducive to avoiding the door body 6220 from knocking against the corners of the main box body 6210 near the door body 6220 during the rotation of the door body 6220 towards the bottom of the main box body 6210.

[0089] But not limited to, when the door body 6220 needs to be rotated to the top of the main box body 6210, B > A, and the vertical height of the first hinge shaft 6241 is less than the vertical height of the third hinge shaft 6251.

[0090] It should be noted that the door body 6220 can be rotated to a position parallel to the bottom of the main box body 6210.

[0091] In an embodiment, C > D, at this time, it can be avoided that the door body 6220 is too far away from the main box body 6210 during rotation, causing the door body 6220 to easily knock against the operator.

[0092] But not limited to, in other embodiments, C can also be less than or equal to D.

[0093] Further, in an embodiment, as Figures 5-6As shown, the first connecting rod 6240 comprises a first rod segment 6243 and a second rod segment 6244 arranged at an angle, and the main box body 6210 is connected to the door body 6220 in sequence through the first rod segment 6243 and the second rod segment 6244, that is, the first rod segment 6243 is arranged close to the first hinge shaft 6241, and the second rod segment 6244 is arranged close to the second hinge shaft 6242. Moreover, the angle formed by the first rod segment 6243 and the second rod segment 6244 is pointed towards the direction away from the door body 6220, and one end of the elastic member 6230 is connected to the main box body 6210, and the other end is connected to the first rod segment 6243.

[0094] Specifically, the connection point of the elastic member 6230 and the main box body 6210 is defined as a first connection point 6231, the connection point of the elastic member 6230 and the first rod segment 6243 is defined as a second connection point 6232, and the third line is the line between the first connection point 6231 and the first hinge shaft 6241. When the door body 6220 is in the state of closing the communication port 6212, the angle between the third line and the first rod segment 6243 is less than 90 degrees.

[0095] In this way, the distance between the first connection point 6231 and the second connection point 6232 can be set closer, avoiding excessive stretching of the elastic member 6230.

[0096] Moreover, in this way, as the first rod segment 6243 rotates, when the door body 6220 rotates from the communication port 6212 to the bottom of the main box body 6210, the stretching amount of the elastic member 6230 shows a trend of increasing. It can be understood that as the door body 6220 moves away from the main box body 6210, the moment of force brought by the gravity of the door body 6220 to the connecting rod mechanism shows a trend of increasing, therefore, the increase of the stretching amount of the elastic member 6230 is beneficial to provide greater pulling force to the door body 6220, so that the door body 6220 can hover in the air at any angle.

[0097] Specifically, in an embodiment, the angle between the first rod segment 6243 and the second rod segment 6244 is 90 degrees.

[0098] In an embodiment, as shown in Figures 5-6 The second connecting rod 6250 is provided with a hook-shaped groove 6253, when the door body 6220 closes the communication port 6212, the second connecting rod 6250 can be clamped in the first hinge shaft 6241 through the hook-shaped groove 6253, when the door body 6220 opens the communication port 6212, the hook-shaped groove 6253 can be separated from the first hinge shaft 6241.

[0099] Specifically, the second connecting rod 6250 is curved towards the direction away from the door body 6220 to form a structure provided with the hook-shaped groove 6253, and the second connecting rod 6250 as a whole is in the shape of an eagle's beak.

[0100] In this way, when the door body 6220 closes the communication opening 6212, the first hinge shaft 6241 can exert a clamping force on the second connecting rod 6250 through the hook-shaped slot 6253, so as to avoid loosening of the door body 6220.

[0101] In an embodiment, two connecting rod mechanisms are respectively arranged on the left and right sides of the main box body 6210 and are respectively connected to the left and right ends of the door body 6220. In this way, the force stability during the opening and closing of the door body 6220 is improved.

[0102] It should be noted that the function box 6200 and the full-embedded integrated structure are both controlled intelligently. The control logic of the full-embedded integrated structure is described below.

[0103] Firstly, the control logic of the range hood part is as follows:

[0104] When the range hood is turned on, the first lifting mechanism drives the function assembly, the air inlet plate group 2000 and the second lifting mechanism to start to descend as a whole, and the distance sensor detects whether the distance between the lowermost end of the full-embedded integrated structure and the pot 7300 is greater than a safety distance for the first time.

[0105] When the distance sensor detects that the distance between the lowermost end of the full-embedded integrated structure and the pot 7300 is greater than the safety distance for the first time, the function assembly, the air inlet plate group 2000 and the second lifting mechanism descend to a position point H2 as a whole, and the second lifting mechanism continues to drive the air inlet plate group 2000 to descend to a position point h1.

[0106] Then, the infrared sensor detects the oil fume concentration. When the oil fume concentration is less than or equal to a set value A1, the air inlet plate group 2000 maintains the position point h1.

[0107] When the oil fume concentration is greater than the set value A1, the controller issues an instruction for the function assembly, the air inlet plate group 2000 and the second lifting mechanism to continue to descend to a position point H3 as a whole, and if the user does not confirm the above instruction to descend to the position point H3 within n seconds, the second lifting mechanism continues to drive the air inlet plate group 2000 to descend to a position point h2, and the rotating speed of the fan assembly 1000 is increased to a high gear.

[0108] If the user confirms the above instruction to descend to the position point H3 within n seconds, the distance sensor detects whether the distance between the lowermost end of the full-embedded integrated structure and the pot 7300 is greater than the safety distance for the second time. When the distance sensor detects that the distance between the lowermost end of the full-embedded integrated structure and the pot 7300 is less than or equal to the safety distance for the second time, the function assembly, the air inlet plate group 2000 and the second lifting mechanism stop descending, the second lifting mechanism continues to drive the air inlet plate group 2000 to descend to the position point h2, and the rotating speed of the fan assembly 1000 is increased to the high gear.

[0109] When the distance between the bottom of the fully embedded integrated structure and the pot 7300 is greater than the safe distance, the functional components, the air inlet plate group 2000 and the second lifting mechanism execute the command to descend as a whole to position point H3, and the air inlet plate group 2000 maintains position point h1.

[0110] Afterwards, the infrared sensor detects the oil fume concentration again. When the oil fume concentration is less than or equal to the set value A1, the positions H3 and h1 are maintained. When the oil fume concentration is greater than the set value A1, the second lifting mechanism continues to drive the air intake plate assembly 2000 to descend to position h2, and the speed of the fan assembly 1000 is increased to high speed.

[0111] When the distance sensor first measures that the distance between the bottom of the fully embedded integrated structure and the pot 7300 is less than or equal to the safe distance, the functional component, the air intake plate group 2000 and the second lifting mechanism stop descending, and the second lifting mechanism drives the air intake plate group 2000 to descend to position point h1.

[0112] Afterwards, the infrared sensor detects the oil fume concentration. When the oil fume concentration is less than or equal to the set value A1, the air intake plate assembly 2000 maintains the position point h1.

[0113] When the oil fume concentration is greater than the set value A1, the second lifting mechanism continues to drive the air intake plate assembly 2000 to descend to position h2, and the speed of the fan assembly 1000 is increased to high speed.

[0114] Next is the control logic for the 6200 function box, as follows:

[0115] Open the function box 6200 and first check if the range hood is running.

[0116] When the range hood is running, it identifies the height information of the functional components, the air intake plate assembly 2000, and the second lifting mechanism, and detects the distance between the bottom of the fully embedded integrated structure and the cookware 7300.

[0117] When the distance between the bottom of the fully embedded integrated structure and the pot 7300 is greater than the safe distance, the first lifting mechanism drives the functional component, the air inlet plate group 2000 and the second lifting mechanism to descend to the position point H11 for placing and taking the function plate. After that, it automatically identifies whether the door 6220 of the function box 6200 is open.

[0118] It should be noted that when the distance between the bottom of the fully embedded integrated structure and the cookware 7300 is less than or equal to the safe distance, the door 6220 of the function box 6200 will be automatically identified as open.

[0119] After the automatic identification of whether the door body 6220 of the function box 6200 is opened, the function box 6200 is continuously identified whether the door body 6220 is closed, and whether the steaming function and the baking function of the function box 6200 are opened;

[0120] After that, the function assembly, the air inlet plate group 2000 and the second lifting mechanism are lowered to the position point H, and the lowering height of the function assembly, the air inlet plate group 2000 and the second lifting mechanism is dynamically adjusted according to the oil fume concentration.

[0121] When the range hood is in a non-running state, the first lifting mechanism drives the function assembly, the air inlet plate group 2000 and the second lifting mechanism to be lowered to the position point H11 of the function disc;

[0122] Then, the automatic identification of whether the door body 6220 of the function box 6200 is opened is performed, and then the function box 6200 is continuously identified whether the door body 6220 is closed, and whether the steaming function and the baking function of the function box 6200 are opened;

[0123] The controller issues a user-operable first lifting mechanism instruction, and if the user does not operate the above instruction within n seconds, the first lifting mechanism drives the function assembly, the air inlet plate group 2000 and the second lifting mechanism to be lowered to the position point H1;

[0124] If the user operates the above instruction within n seconds, the first lifting mechanism drives the function assembly, the air inlet plate group 2000 and the second lifting mechanism to be lowered to the position specified by the user.

[0125] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.

It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are within the protection scope of the present application.
