Generally, the stove in a home kitchen is equipped with a double cooker, which makes the width of the smoke damper wider. When the smoke damper moves to open the range hood outlet, due to its wide width, it is necessary to maintain the synchronization of the movements of the left and right sides of the smoke damper to avoid jamming and other situations. Especially when the smoke damper has more than one opening action, jamming is particularly prone to occur, which affects the smoothness of the opening. Utility Model Content

[0023] An integrated stove comprises the range hood.

[0024] Beneficial effects of the utility model:

[0025] 1. By setting a plurality of horizontally spaced linkage components and connections between the smoke shield, the number of connection points and the distribution of connection positions of the smoke shield 2 are increased, and by connecting the synchronization rod and each linkage component, one linkage component is an active structure and the other linkage components are driven structures, thereby improving the smoothness and stability of the movement of the smoke shield, and avoiding the height difference between the left and right sides of the smoke shield or even the jamming during the movement;

[0039] The utility model is further described in detail below based on the accompanying drawings and implementation cases.

[0040] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0041] Implementation Case 1:

[0042] A range hood is mainly used in an integrated stove and can also be set up independently of other kitchen appliances. Figure 1-8 , including a casing 1, a smoke baffle 2, a driving mechanism and a detector 6, wherein the casing 1 is an upright hollow structure, specifically installed at the rear side of the corresponding stove, a smoke inlet h1 is arranged on the front plate of the casing 1, and the smoke baffle 2 is arranged at the smoke inlet h1. When the range hood is not in operation, the smoke baffle 2 blocks the smoke inlet h1. In one embodiment, the smoke baffle 2 is flush with the front plate of the casing 1 when blocking the smoke inlet h1, so that the front of the casing 1 presents a complete and smooth surface. An air duct is formed in the internal space of the casing 1, and the range hood is equipped with a fan. When the smoke baffle 2 opens the smoke inlet h1, the fan is started to form a negative pressure at the smoke inlet h1, so that the oil smoke is sucked from the smoke inlet h1 into the air duct inside the casing 1 to implement oil smoke suction.

[0043] The driving mechanism is arranged in the housing 1, and is used to drive the smoke baffle 2 to move. In this embodiment, the driving mechanism has two driving modes, which are used to drive the smoke baffle 2 to translate to the first state and to drive the smoke baffle 2 to flip to the second state. In the first state, at least one edge of the translated smoke baffle 2 will have a gap with the edge corresponding to the smoke inlet h1, so that the oil smoke can be sucked into the housing 1 through the gap. Since the smoke baffle 2 will not occupy the space in the vertical direction of the stove during the translation process, the smoke baffle 2 will not interfere with or collide with the pot during the translation process. In the second state, the flipped smoke baffle 2 can fully open the smoke inlet h1, and has a larger oil smoke absorption area than the first state, but will occupy the space in the vertical direction of the stove during the flipping process, so that the smoke baffle 2 will interfere with or collide with the higher pot during the flipping process.

[0044] In the present embodiment, the detector 6 is used to detect the height of the cookware, so as to determine whether the smoke shield 2 will interfere with or collide with the cookware during the flipping process. According to the detection structure of the detector 6, in the application scenario where the cookware is relatively high, the driving mechanism drives the smoke shield 2 to the first state; in the application scenario where the cookware is relatively low, the driving mechanism drives the smoke shield 2 to the second state. That is, the detector 6 provides the driving mechanism with the judgment condition for driving the smoke shield 2 to the first state or the second state.

[0045] In the range hood of this embodiment, the smoke shield 2 has a first state and a second state. In the first state, the smoke shield 2 has a smaller oil fume absorption area, but there is no risk of interfering with or colliding with cookware. In the second state, the smoke shield 2 has a larger oil fume absorption area, but there is a risk of interfering with or colliding with higher cookware. By detecting the height of the cookware by the detector 6, different states of the smoke shield 2 are selected to match application requirements, thereby avoiding safety hazards caused by the smoke shield 2 colliding with the cookware, and having high application adaptability.

[0046] In this embodiment, during the process of the driving mechanism driving the smoke baffle 2 to translate, the smoke baffle 2 gradually moves away from the front plate of the housing 1, that is, the smoke baffle 2 will gradually move toward the front of the housing 1, so that an upper smoke inlet gap h2 is formed between the top edge of the smoke baffle 2 and the upper edge of the smoke inlet h1, and the oil smoke above the high position can enter the housing 1 through the upper smoke inlet gap h2, and a lower smoke inlet gap h3 is formed between the bottom edge of the smoke baffle 2 and the lower edge of the smoke inlet h1, and the oil smoke at the low position can enter the housing 1 through the lower smoke inlet gap h3. In this embodiment, the smoke baffle 2 in the first state is suitable for the application scene of the cooker with a higher position, and the smoke baffle 2 is translated to form an upper smoke inlet gap h2 and a lower smoke inlet gap h3 at the high position and the low position, respectively, so as to expand the smoke range of the range hood in the vertical direction and improve the effect of oil smoke absorption, which is particularly suitable for the type of cooker with multiple oil smoke outlets in the vertical direction, such as a multi-layer stacked steamer.

[0047] In this embodiment, further, during the process of the driving mechanism driving the smoke baffle 2 to translate, the height of the smoke baffle 2 gradually increases, that is, the translation of the smoke baffle 2 is along the oblique upper front direction. Since the translation of the smoke baffle 2 gradually increases its height, the width of the upper smoke inlet gap h2 and the lower smoke inlet gap h3 can be further expanded, thereby expanding the oil fume absorbing area and improving the oil fume absorbing effect. In addition, the oblique movement of the smoke baffle 2 can prevent the edges of the smoke baffle 2 and the smoke inlet h1 and the front plate of the housing 1 from making abnormal noises due to scratches, or even damage caused by collisions.

[0048] In the present implementation case, the driving mechanism drives the smoke shield 2 to flip and connect after the driving mechanism drives the smoke shield 2 to translate. Since the two driving processes are connected, the driving mechanism is only configured with one set of driving modes. This driving mode has two nodes. The driving mode completes the first node corresponding to the smoke shield 2 being in the first state halfway, and completes the second node corresponding to the smoke shield 2 being in the second state fullway.

[0049] Firstly, the driving mechanism only needs to set a set of driving modes to complete the first state and the second state of the smoke baffle 2, so that the driving mechanism is simplified in terms of both the composition configuration and the driving mechanism; secondly, when the smoke baffle 2 is translated from the initial state of closing the smoke inlet h1 to the first state, the height of the smoke baffle 2 can be increased. When the height of the smoke baffle 2 is raised, the smoke baffle 2 is flipped over again, and the height of the vertical space occupied by the stove can be increased during the flipping process, so that the height of the pots that can be adapted to the second state of the smoke baffle 2 is increased, that is, it has higher adaptability.

[0050] Based on this, in the present embodiment, regardless of the height of the cookware, the driving mechanism first drives the smoke baffle 2 to translate, and after the smoke baffle 2 translates to the first state, the detector 6 detects whether the height of the cookware is higher than the preset height. If so, it means that the flipping of the smoke baffle 2 will collide with the cookware, and the smoke baffle 2 maintains the first state, and the fumes generated by the cookware are sucked into the casing 1 through the upper smoke inlet gap h2 and the lower smoke inlet gap h3; if not, it means that the flipping of the smoke baffle 2 will not collide with the cookware, and the driving mechanism continues to drive the smoke baffle 2, so that the smoke baffle 2 flips to the second state, and the fumes are sucked into the casing 1 through the fully open smoke inlet h1.

[0051] In this embodiment, the detector 6 is arranged in the casing 1, and the position corresponds to the preset height of the cookware. When the smoke baffle 2 closes the smoke inlet h1, the detector 6 is enclosed in the casing 1. Since the driving mechanism drives the smoke baffle 2 to translate to the first state, there is no need to detect the height of the cookware. The casing 1 provides better protection for the detector 6. When the smoke baffle 2 is in the first state, the detector 6 can obtain the detection field of view through the lower smoke inlet gap h3. After detection, it can be determined whether the driver 41 needs to drive the smoke baffle 2 to flip to the second state.

[0052] In this embodiment, the detector 6 is configured as an infrared detector, which can sense and identify objects at a long distance, has high detection sensitivity, and is low in cost, and is suitable for detecting the height of the cookware.

[0053] In this embodiment, the smoke inlet h1 is arranged at the upper part of the front plate of the casing 1, and the portion of the front plate of the casing 1 from its bottom side to the bottom edge of the smoke inlet h1 forms a smoke guide plate 11. Whether the smoke shield plate 2 is in the first state or the second state, under the action of the negative pressure environment of the smoke inlet h1, the smoke guide plate 11 can play a better role in guiding the flow of oil smoke, so that the oil smoke flows upward along the smoke guide plate 11 and enters the interior of the casing 1.

[0054] In this embodiment, the driving mechanism includes a driving component and a linkage component 3, wherein the driving component includes a driver 41 and a push rod 42, the push rod 42 is rotatably connected in the housing 1, the driver 41 is used to drive the push rod 42 to telescopically move, and the driver 41 can specifically use a driving motor. The linkage component 3 is arranged in the housing 1, the push rod 42 is connected to the linkage component 3, and the linkage component 3 fixes the smoke baffle 2, so that the push rod 42 telescopically moves under the drive of the driver 41, and the smoke baffle 2 is driven by the linkage component 3 to translate, connect and flip, so that the smoke baffle 2 is first driven to the first state and then driven to the second state.

[0055] In this embodiment, a plurality of linkage components 3 are arranged in the housing 1, and these linkage components 3 are arranged horizontally at intervals in the housing 1, and are all connected to the smoke baffle 2, one of the linkage components 3 is rotationally connected to the push rod 42, that is, one of the linkage components 3 is driven by the driving component to drive the smoke baffle 2 to complete the translation, connection and flipping movement, and a horizontal synchronization rod 5 is also arranged in the housing 1, and all the linkage components 3 in the housing 1 are connected to the synchronization rod 5. By setting up a plurality of horizontally spaced linkage components 3 and the connection of the smoke baffle 2, the connection points and connection position distribution of the smoke baffle 2 are increased, and through the connection of the synchronization rod 5 and each linkage component 3, one of the linkage components 3 is an active structure, and the remaining linkage components 3 are driven structures, thereby improving the smoothness and stability of the movement of the smoke baffle 2, and avoiding the height difference between the left and right sides of the smoke baffle 2 or even the jamming during the movement.

[0056] In the present embodiment, further, three linkage components 3 are arranged in the casing 1, and these three linkage components 3 are respectively connected to the middle part and two side parts of the smoke damper 2, wherein the linkage component 3 connected to the middle part of the smoke damper 2 rotates to connect the push rod 42, that is, the driving force applied by the driving component is transmitted to the smoke damper 2 through the linkage component 3 located in the middle, so that the force acting on the smoke damper 2 can be kept balanced on the left and right, and the linkage components 3 on both sides are connected to the side parts of the smoke damper 2. On the one hand, as a driven structure, it can improve the smoothness and stability of the smoke damper 2 during movement. On the other hand, the two linkage components 3 located on the outside can serve as the bracket structure of the smoke damper 2, and can provide better support for the smoke damper 2.

[0057] As for the linkage assembly 3 connected to the middle part of the smoke baffle 2, in this embodiment, it includes a sliding seat 31a, a translation structure 32a, a guide rail 33a, and a connecting arm 34a. Among them, the sliding seat 31a is arranged in the housing 1, the translation structure 32a is slidably connected to the sliding seat 31a, the translation structure 32a can slide along the sliding seat 31a, and the sliding direction is parallel to the translation direction of the smoke baffle 2, so that the translation structure 32a has a moving track that matches the translation of the smoke baffle 2, the guide rail 33a has a track that matches the translation connection and flipping of the smoke baffle 2, and the connecting arm 34a has a first connecting part 34a-1, a second connecting part 34a-2, a third connecting part 34a-3 and a matching part 34a-4, the first connecting part 34a-1 is rotatably connected to the translation structure 32a, the second connecting part 34a-2 is fixedly connected to the smoke baffle 2, the third connecting part 34a-3 is rotatably connected to the push rod 42, and the matching part 34a-4 is slidably connected to the guide rail 33a. In the present embodiment, the guide rail 33a is provided to match the moving trajectory of the translation, connection and flipping of the smoke baffle 2, so that two different moving actions of the smoke baffle 2 can be completed by a set of structures, which can simplify the structural composition configuration, compress the installation space and save costs; in fact, in the process of the smoke baffle 2 being translated from the initial state to the first state, the detector 6 completes the detection of the height of the cookware. When the cookware meets the requirement of not higher than the preset height, the smoke baffle 2 will not stop in the first state but will be directly driven to the second state. Through the continuous start-up of the driver 41, the translation structure 32a drives the connecting arm 34a to move obliquely and linearly, and the connecting arm 34a flips around the translation structure 32a, thereby completing the translation, flipping and connection of the smoke baffle 2, without the need for different components to cooperate, thereby avoiding the jamming of the smoke baffle 2 and improving the smoothness and fluency; in addition, the translation structure 32a is slidably connected to the sliding seat 31a, which can improve the stability of the connecting arm 34a during the driving process and avoid the occurrence of shaking and other situations that affect the movement stability of the smoke baffle 2.

[0058] In this embodiment, the translation structures 32a of the linkage assembly 3 are all connected to the synchronization rod 5. The linkage assembly 3 connected to the middle of the smoke baffle 2 has a connecting sleeve 521 extending horizontally and fixedly sleeved on the synchronization rod 5. Since the overall length of the synchronization rod 5 is relatively long, which is substantially the same as the left and right widths of the housing 1, and the push rod 42 acts on the linkage assembly 3 connected to the middle of the smoke baffle 2, the middle of the synchronization rod 5 is a concentrated force point, which makes it easy for the middle of the synchronization rod 5 to be completely deformed. Therefore, by providing the connecting sleeve 521, the force can be dispersed, which plays a role in preventing the synchronization rod 5 from being easily bent. In addition, the translation structures 32a of the three linkage assemblies 3 are connected to the synchronization rod 5.

[0059] In this embodiment, the guide rail 33a has a first guide rail 33a-1, a second guide rail 33a-2 and a transition guide rail 33a-3. The first guide rail 33a-1 has a straight track parallel to the translation direction of the smoke damper 2 to match the translation of the smoke damper 2. The second guide rail 33a-2 has an arc track in the same direction as the flipping direction of the smoke damper 2 to match the flipping of the smoke damper 2. When the matching part 34a-4 slides onto the second guide rail 33a-2, the second guide rail 33a-2 takes the second rotating part as the center of the circle, and the transition guide rail 33a-3 connects the first guide rail 33a-1 and the second guide rail 33a-2 to match the connection process of the translation and flipping of the smoke damper 2. When starting, the driver 41 drives the push rod 42 to gradually extend, and the extension direction of the push rod 42 remains unchanged. At this time, the matching part 34a-4 moves along the first guide rail 33a-1 and the translation structure 32a moves obliquely and linearly along the sliding seat 31a, and the matching part 34a-4 slides to the transition guide rail 33a-3, and the translation structure 32a moves from the lowest position to the highest position, driving the connecting arm 34a to translate from the lowest position to the highest position, so that the smoke damper 2 is translated from the initial state to the first state; the matching part 34a-4 slides along the transition guide rail 33a-3, and the smoke damper 2 completes the transition from translation to flipping; the matching part 34a-4 slides along the second guide rail 33a-2 and rotates around the second connecting part 34a-2, so that the translation structure 32a of the smoke damper 2 remains motionless in the highest position during the flipping process, that is, there will be no shaking or other conditions that affect the flipping stability during the flipping process of the smoke damper 2, and the smoke damper 2 gradually flips from the first state to the second state.

[0060] In this embodiment, the transition guide rail 33a-3 is set as an arc track, so that there will be no jamming in the process of the smoke shield 2 transitioning from translation to flipping, thereby improving the smoothness of the transition process between the translation and flipping of the smoke shield 2.

[0061] In this embodiment, the guide rail 33a is configured as a linear groove, that is, the first guide rail 33a-1 is a straight groove, the transition guide rail 33a-3 is an arc-shaped groove, and the second guide rail 33a-2 is an arc-shaped groove. The matching part 34a-4 is movably embedded in the linear groove. The matching part 34a-4 is specifically configured as a circular structure, and a sliding sleeve is provided on the outer sleeve to improve the smoothness of the sliding of the matching part 34a-4 in the linear groove.

[0062] In this embodiment, the bottom end of the push rod 42 is rotatably connected to the rear plate in the housing 1, and the top end is rotatably connected to the third connection portion 34a-3 of the translation structure 32a. A longitudinal shield 12 is provided in the housing 1, and the push rod 42 and the driver 41 are both located in the longitudinal shield 12. The longitudinal shield 12 protects the driver 41 and the push rod 42, and can prevent the oil smoke from adhering to the push rod 42 and the driver 41 during the flow in the housing 1. The longitudinal shield 12 has a window 121 at the position corresponding to the connecting arm 34a, so that the connecting arm 34a extends out of the longitudinal shield 12 to connect to the middle of the smoke baffle 2.

[0063] In this embodiment, a reinforcing rib 13 is provided on the rear plate of the casing 1. The reinforcing rib 13 extends longitudinally and has a certain width. The overall structure is a flat plate structure, which is used to enhance the structural strength of the rear plate. A fixing seat 421 is provided on the reinforcing rib 13. The fixing seat 421 is detachably connected to the reinforcing rib 13 through a fastener. The bottom end of the push rod 42 is rotatably connected to the fixing seat 421. The translation structure 32a is provided on the reinforcing rib 13. The reinforcing rib 13 is provided not only to reinforce the rear plate of the casing 1, but also the translation structure 32a and the fixing seat 421 are connected to the position where the reinforcing rib 13 is provided, thereby improving the firmness of the drive assembly and the linkage assembly 3 provided on the rear plate of the casing 1, and having a stronger load strength.

[0064] In this embodiment, the top of the push rod 42 has a connecting section 422 bent toward the front plate of the casing 1, and the third connecting portion 34a-3 of the push rod 42 is rotatably connected to the connecting section 422. Since the connecting section 422 is bent toward the front plate, the push rod 42 is closer to the rear plate of the casing 1, so that the width of the longitudinal shield 12 in the front-to-back direction can be reduced while avoiding interference and collision with the push rod 42, thereby reducing the space it occupies inside the casing 1, thereby increasing the flow of oil smoke inside the casing 1.

[0065] In this embodiment, for the linkage assembly 3 connected to the smoke baffle 2, two connecting arms 34a and two guide rails 33a are provided, and the connecting arms 34a and the guide rails 33a are symmetrically arranged on the left and right sides, wherein the guide rails 33a are connected to the left and right sides of the sliding seat 31a, and the guide rails 33a can be detachably connected to the sliding seat 31a, and can also be set as an integrated structure with the sliding seat 31a, the first connecting parts 34a-1 of the two connecting arms 34a are respectively rotatably connected to the two sides of the translation structure 32a, and the third connecting parts 34a-3 of the two connecting arms 34a are respectively rotatably connected to the two sides of the push rod 42, and the matching parts 34a-4 of the two connecting arms 34a are respectively slidably connected to the corresponding guide rails 33a, and the two guide rails 33a and the two connecting arms 34a symmetrically arranged on the left and right sides make the force more balanced, and can share the force load when driven by the driven component, thereby playing a role in protecting the structure.

[0066] In this embodiment, the second connecting parts 34a-2 of the two connecting arms 34a are connected to the same mounting member 35a, and the mounting member 35a is fixedly connected to the middle part of the smoke baffle 2. By setting the mounting member 35a, the two connecting arms 34a can be strengthened to form an integral structure, thereby improving the overall structural strength and the load-bearing capacity.

[0067] As for the linkage assembly 3 connected to the side of the smoke damper 2, in the present embodiment, it includes a sliding seat 31b, a translation structure 32b, a guide rail 33b and a connecting arm 34b, and is structurally the same as the linkage assembly 3 connected to the middle of the smoke damper 2, except that the connecting arm 34b connected to the side of the smoke damper 2 is not connected to the push rod 42, and therefore does not have a third connecting portion 34a-3, but only a first connecting portion 34b-1, a second connecting portion 34b-2 and a matching portion 34b-4, and the guide rail 33b is also provided with a first guide rail 33b-1, a second guide rail 33b-2 and a transition guide rail 33b-3. In addition, the linkage assembly 3 connected to the side of the smoke damper 2 is a single guide rail 33b and a single connecting arm 34b structure. Except for these two differences, the rest is the same as the linkage assembly 3 connected to the smoke damper 2, and will not be repeated here.

[0068] In the present embodiment, the linkage assembly 3 connected to the side of the smoke baffle 2 has a smoke collecting plate 21 connected to its connecting arm 34b, so that when the smoke baffle 2 is flipped to the second state, the two smoke collecting plates 21 located on both sides of the smoke baffle 2 can collect the smoke and prevent the smoke from escaping to the two sides of the smoke outlet, thereby improving the smoke collection rate of the smoke outlet.

[0069] In the present embodiment, the side of the smoke damper 2 has a connecting rib 22 protruding toward the direction of the oil smoke outlet, and the linkage assembly 3 connected to the side of the smoke damper 2, its connecting arm 34b and the corresponding smoke collecting plate 21 are connected to the connecting rib 22, and the connecting member and the connecting arm 34b and the smoke collecting plate 21 can be detachably connected by fasteners, which is convenient for disassembly and maintenance. By setting the connecting rib 22, the connection firmness between the smoke damper 2 and the connecting arm 34b and the smoke collecting plate 21 can be enhanced to avoid loose structure, etc., especially after long-term use, the connection of the smoke collecting plate 21 becomes loose, resulting in scratches between the smoke collecting plate 21 and the casing 1 during the translation or flipping of the smoke damper 2.

[0070] In this embodiment, a transverse shield 14 extending in the horizontal direction is provided in the casing 1, and the three linkage components 3 and the synchronization rod 5 are all located in the transverse shield 14, which can prevent the smoke from adhering to the linkage components 3 and the synchronization rod 5 during the flow in the casing 1. The transverse shield 14 is provided with a window 141 at the position corresponding to the connecting arm 34b, so that the connecting arm 34b extends out of the transverse shield 14. In addition, the window 141 located in the middle of the transverse shield 14 and the window 121 of the longitudinal shield 12 are connected to each other.
