[0046] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0047] It should be noted that the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0048] In the present invention, unless otherwise clearly defined and limited, terms such as "installation", "connection", "fixation" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection or communication with each other; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal connection of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] In the present invention, unless otherwise clearly specified or limited, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or merely indicates that the horizontal height of the first feature is less than that of the second feature.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0051] In the related art, there is a problem of low oil fume suction efficiency in integrated stoves. Through research, it is found that the reason for this problem is that the smoke guide plate is located below the smoke inlet, the smoke guide plate hinders the oil fume from entering the smoke inlet passage, and at the same time, there is no smoke gathering effect above the smoke inlet, resulting in the problem of low oil fume suction efficiency in the integrated stove.

[0052] To solve the above problems, an embodiment of the present invention provides a machine head assembly and an integrated stove. By arranging a smoke guide plate assembly in the smoke inlet, the smoke guide plate assembly includes two smoke guide plates. The two smoke guide plates can rise and open in the smoke inlet, or the two smoke guide plates can descend and close in the smoke inlet. Thus, the two smoke guide plates of the smoke guide plate assembly can rise in the smoke inlet, and after opening, they do not hinder the oil fume from entering the smoke inlet passage, and the two smoke guide plates of the smoke guide plate assembly and the top of the smoke collecting hood form a smoke gathering area, thereby improving the oil fume suction efficiency without changing the air intake volume.

[0053] The following will specifically describe the machine head assembly and the integrated stove provided by the embodiment of the present invention in conjunction with specific embodiments.

[0054] First, refer to Figure 1 , define the length direction of the integrated stove as the X direction, define the width direction of the integrated stove as the Y direction, and define the height direction and the vertical direction of the integrated stove as the Z direction.

[0055] Refer to Figure 1 andFigure 2 As shown, an embodiment of the present invention provides a head assembly 100, which is applied to an integrated stove. The integrated stove includes a lower computer 200, a stove main body 300, and a head assembly 100. The lower computer 200 mainly provides a storage cabinet space and a space for installing a range hood. The stove main body 300 is mainly used to provide a cooking appliance for cooking. The head assembly 100 is mainly used to cooperate with the range hood to generate negative pressure to suck away the oil fume generated during cooking. The head assembly 100, the stove main body 300, and the lower computer 200 are arranged in sequence along the Z direction and are fixedly connected relatively to improve the stability of the integrated stove. The cooking appliance may include a burner, a pot rack, etc.

[0056] The length direction of the head assembly 100 is the same as the length direction of the integrated stove, the width direction of the head assembly 100 is the same as the width direction of the integrated stove, and the height direction of the head assembly 100 is the same as the height direction of the integrated stove.

[0057] One side of the head assembly 100 in the +X direction is the left side, and one side of the head assembly 100 in the -X direction is the right side.

[0058] In some embodiments, as shown in Figures 1 to 3 As shown, the head assembly 100 includes a smoke collecting hood 10. The smoke collecting hood 10 has a smoke inlet passage and a smoke inlet 13 communicating with the smoke inlet passage. The smoke inlet passage is communicated with the flue of the range hood installed in the lower computer 200. In this way, the oil fume generated during the cooking process can enter the smoke inlet passage along the smoke inlet 13 under the negative pressure of the range hood and is finally discharged through the flue.

[0059] In some examples, the smoke collecting hood 10 includes a smoke collecting hood main body 11 and a placing table 12. The placing table 12 is at least partially located on one side of the smoke collecting hood main body 11 in the +Y axis direction, and the placing table 12 is connected to the smoke collecting hood main body 11.

[0060] In some examples, the smoke collecting hood 10 may have a plurality of smoke inlets 13, and the plurality of smoke inlets 13 are arranged in sequence along the length direction of the head assembly 100. With this arrangement, the oil fume generated during cooking can enter the smoke inlet passage through the plurality of smoke inlets 13, which can improve the oil fume suction efficiency. In other examples, the smoke collecting hood 10 may also have one smoke inlet 13.

[0061] The head assembly 100 further includes a smoke guiding plate assembly. The smoke guiding plate assembly is arranged in the smoke inlet 13, and the smoke guiding plate assembly includes two smoke guiding plates.

[0062] The number of the smoke guiding plate assemblies is equal to the number of the smoke inlets 13.

[0063] The machine head assembly 100 further includes a first driving mechanism, which is installed on the smoke collecting hood 10. The first driving mechanism is connected to the smoke guiding plate assembly, and the first driving mechanism is used to drive the smoke guiding plate assembly to rise or fall along the height direction of the machine head assembly 100.

[0064] The first driving mechanism can be installed inside the smoke collecting hood 10. In other embodiments, the first driving mechanism can be installed outside the smoke collecting hood 10.

[0065] It should be noted that in the height direction of the integrated stove, the size of the smoke guiding plate is smaller than the size of the smoke inlet 13. With such a setting, the smoke guiding plate assembly can rise or fall within the smoke inlet 13.

[0066] The machine head assembly 100 further includes a second driving mechanism, which is installed on the smoke collecting hood 10. The second driving mechanism is connected to the smoke guiding plate assembly, and the second driving mechanism is used to drive the smoke guiding plate of the smoke guiding plate assembly to rotate relative to the smoke collecting hood 10.

[0067] The second driving mechanism can be installed inside the smoke collecting hood 10. In other embodiments, the second driving mechanism can also be installed outside the smoke collecting hood 10.

[0068] Wherein, the two smoke guiding plates of the smoke guiding plate assembly can rotate under the driving force of the second driving mechanism, and the rotation directions of the two smoke guiding plates of the smoke guiding plate assembly are opposite.

[0069] In some examples, the smoke collecting hood 10 has two smoke inlets 13, and each smoke inlet 13 corresponds to a cooking appliance. A smoke guiding plate assembly is arranged in each smoke inlet 13. The first driving mechanism can be connected to the two smoke guiding plate assemblies, and the second driving mechanism can be connected to the two smoke guiding plate assemblies. With such a setting, the two smoke guiding plate assemblies can be driven to rise or fall simultaneously by the first driving mechanism; the two smoke guiding plate assemblies can be driven to open or close simultaneously by the second driving mechanism.

[0070] See Figure 1 As shown, when the integrated stove is in a non-working state, the two smoke guiding plates of the two smoke guiding plate assemblies are located below the smoke collecting hood 10, that is, the two smoke guiding plates of each smoke guiding plate assembly are located on one side of the smoke inlet 13 in the -Z direction, the two smoke guiding plates of each smoke guiding plate assembly are in a closed state, and the two smoke guiding plates of each smoke guiding plate assembly can block a part of the smoke inlet 13. At this time, the smoke guiding plate assembly can be used as a decorative part.

[0071] See Figure 2As shown, when the integrated range hood is working, the first driving mechanism drives the two smoke guide plate assemblies to rise along the height direction of the machine head assembly 100, that is, the first driving mechanism drives the two smoke guide plate assemblies to rise along the +Z direction, so that the two smoke guide plates of each smoke guide plate assembly are located above the smoke collecting hood 10. The second driving mechanism drives the smoke guide plates of the two smoke guide plate assemblies to rotate relative to the smoke collecting hood 10, so that the two smoke guide plates of each smoke guide plate assembly rotate in a direction away from the smoke inlet 13 at the middle end of the smoke inlet 13, so that the two smoke guide plates of each smoke guide plate assembly extend in the +Y direction, which can make the two smoke guide plates of each smoke guide plate assembly in an open state. The two smoke guide plates of each smoke guide plate assembly are respectively located on both sides of the smoke inlet 13 in the length direction of the machine head assembly 100, and the two smoke guide plates of each smoke guide plate assembly do not block the smoke inlet 13. At this time, a smoke gathering area is formed between the two smoke guide plates of each smoke guide plate assembly and the top of the smoke collecting hood 10, that is, a smoke gathering area is formed between the two smoke guide plates of each smoke guide plate assembly and the placing table 12.

[0072] It should be noted that the driving force of the first driving mechanism can come from the first driving mechanism itself or from the second driving mechanism. The driving force of the second driving mechanism can come from the second driving mechanism itself or from the first driving mechanism.

[0073] In the machine head assembly 100 provided by the embodiment of the present invention, the first driving mechanism drives the smoke guide plate assembly to rise along the height direction of the machine head assembly 100, and the second driving mechanism drives the smoke guide plates of the smoke guide plate assembly to rotate relative to the smoke collecting hood 10, so that the two smoke guide plates of the smoke guide plate assembly can be located above the smoke collecting hood 10 and opened, so that the two smoke guide plates of the smoke guide plate assembly do not block the oil fume from entering the smoke inlet passage, and a smoke gathering area is formed between the two smoke guide plates of the smoke guide plate assembly and the top of the smoke collecting hood 10, thereby improving the oil fume suction efficiency without changing the air intake volume.

[0074] By driving the smoke guide plate assembly to descend along the height direction of the machine head assembly 100 by the first driving mechanism and driving the smoke guide plates of the smoke guide plate assembly to rotate relative to the smoke collecting hood 10 by the second driving mechanism, the two smoke guide plates of the smoke guide plate assembly can be located below the smoke collecting hood 10 and closed, so that the smoke guide plate assembly can be used as a decorative part when the integrated range hood is in a non-working state.

[0075] By opening or closing the two smoke guide plates in the smoke inlet 13 under the action of the second driving mechanism, compared with setting one smoke guide plate relative to the smoke inlet 13, the opening and closing radius of the smoke guide plate can be reduced, and there will be no interference with the cooking appliance (burner, pot rack, etc.) during the opening and closing process.

[0076] It should also be pointed out that when the integrated stove is not in operation, the side of the smoke guide plate facing the smoke inlet channel is the inner side of the smoke guide plate, and the side of the smoke guide plate facing away from the smoke inlet channel is the outer side of the smoke guide plate. When the integrated stove is in operation, the smoke guide plate rotates open, the inner side of the smoke guide plate is in the oil fume passage, and the outer side of the smoke guide plate avoids the oil fume passage. When the integrated stove is used, the smoke guide plate descends and rotates closed, and the inner side of the smoke guide plate is in the oil fume passage, which can prevent the outer side of the smoke guide plate from being easily stained with oil. Even if the inner side of the smoke guide plate is stained with oil, after the integrated stove is used, the oil will drip from the surface into the internal oil passage of the integrated stove, and will not drip onto the outside of the integrated stove to cause stains.

[0077] In a possible implementation, the first driving mechanism includes a driving assembly, a lifting assembly and a rotating arm assembly, the driving assembly is connected to the smoke hood 10, the lifting assembly is connected to the driving assembly, and the rotating arm assembly is connected to the lifting assembly.

[0078] The rotating arm assembly includes a plurality of rotating arms, which are arranged at intervals along the length direction of the head assembly 100, and are respectively connected to each smoke guide plate of the two smoke guide plate assemblies, that is, each rotating arm is connected to a smoke guide plate.

[0079] The lifting assembly can drive the multiple rotating arms to rise or fall along the height direction of the head assembly 100. In this way, the lifting assembly moves under the action of the driving assembly, and the lifting assembly can drive the corresponding smoke guide plate to rise or fall along the height direction of the head assembly 100 through each rotating arm, so that the two smoke guide plate assemblies can be raised or lowered at the same time.

[0080] Among them, see Figure 4 and Figure 5 As shown, the driving assembly may include a driving motor 31, a transmission shaft 32 and a plurality of first transmissions.

[0081] The driving motor 31 is disposed inside the smoke collecting hood 10 , the transmission shaft 32 is connected to the driving motor 31 , and the plurality of first transmissions are respectively connected to the transmission shaft 32 .

[0082] Exemplarily, the drive motor 31 can be installed inside the storage table 12 through a motor seat. The transmission shaft 32 is connected to the drive motor 31, and the transmission shaft 32 extends along the length direction of the head assembly 100. The drive motor 31 can drive the transmission shaft 32 to rotate. The first transmission device can be made of a worm gear, and multiple first transmission devices are connected to the transmission shaft 32. The transmission shaft 32 can drive the lifting assembly to rise or fall along the height direction of the head assembly 100 through multiple first transmission devices.

[0083] In one possible implementation, see Figures 6 to 8As shown, the lifting assembly may include a plurality of lead screws, a plurality of first brackets, and at least one second bracket 46. Each lead screw extends along the height direction of the head assembly 100. Each lead screw is connected to a first driver. Each first bracket and each second bracket 46 are connected to a lead screw. Each first bracket is connected to a swing arm, and each second bracket 46 is connected to two swing arms. With such an arrangement, the drive shaft 32 can drive a plurality of lead screws through a plurality of first drivers. The plurality of lead screws can drive the plurality of first brackets and at least one second bracket 46 to rise or fall along the height direction of the head assembly 100. The first bracket and the second bracket 46 can drive the corresponding smoke guide plate to rise or fall along the height direction of the head assembly 100 through the swing arm.

[0084] Among them, the lead screw can be a ball screw. The screw shaft of the lead screw is connected to the first driver. The screw shaft extends along the height direction of the head assembly 100. The drive shaft 32 can drive the screw shaft to rotate through the first driver, and the screw shaft can drive the nut of the lead screw to rise or fall along the height direction of the head assembly 100.

[0085] The first bracket is fixedly connected to the nut of the corresponding lead screw.

[0086] The first bracket has a first limiting groove 47. A part of the swing arm is located in the first limiting groove 47. The first bracket can limit the swing arm in the height direction of the head assembly 100 through the first limiting groove 47, so that the first bracket can drive the corresponding smoke guide plate to rise or fall along the height direction of the head assembly 100 through the swing arm.

[0087] The second bracket 46 is fixedly connected to the nut of the corresponding lead screw.

[0088] The second bracket 46 has two second limiting grooves 48. A part of the two swing arms are respectively located in the two second limiting grooves 48. The second bracket 46 can limit the swing arm in the height direction of the head assembly 100 through the second limiting grooves 48, so that the second bracket 46 can drive the corresponding two smoke guide plates to rise or fall along the height direction of the head assembly 100 through the two swing arms.

[0089] In a possible implementation manner, each second bracket 46 is rotatably connected to two adjacent swing arms, and each first bracket is rotatably connected to one of the remaining two swing arms of the swing arm assembly. With such an arrangement, when the swing arm drives the smoke guide plate to rotate, interference between the swing arm and the first bracket and the second bracket 46 can be avoided.

[0090] Among them, the head assembly 100 may include two smoke guide plate assemblies. The smoke guide plate assembly located on the left side of the head assembly 100 may include a first smoke guide plate 21 and a second smoke guide plate 22. The smoke guide plate assembly located on the right side of the head assembly 100 may include a third smoke guide plate 23 and a fourth smoke guide plate 24.

[0094] The lifting assembly includes three lead screws, namely a first lead screw 41, a second lead screw 42 and a third lead screw 43. The nut of the first lead screw 41 is fixedly connected to the bracket one 44. The nut of the second lead screw 42 is fixedly connected to the second bracket 46. The nut of the third lead screw 43 is fixedly connected to the bracket two 45.

[0095] The driving assembly may include three first drivers. The three first drivers are respectively a driver one 33, a driver two 34 and a driver three 35. The driver one 33 is connected to the lead screw shaft of the first lead screw 41. The driver two 34 is connected to the lead screw shaft of the second lead screw 42. The driver three 35 is connected to the lead screw shaft of the third lead screw 43.

[0096] In a possible implementation manner, refer to Figures 6 to 8As shown, the second driving mechanism includes a driven component, a connecting rod component, and a rotating component. The driven component is connected to the lifting component, the connecting rod component is connected to the rotating component, and the driven component drives the rotating component to rotate through the connecting rod component. With such a setting, the driving force of the second driving mechanism can be derived from the first driving mechanism, which can reduce independent driving sources and thus reduce costs.

[0097] Among them, a plurality of rotating arms are connected to the rotating component, and the rotating component drives the plurality of rotating arms to rotate. With such a setting, the rotating component can drive the corresponding smoke guide plates to rotate relative to the smoke collecting hood 10 through the respective rotating arms, so that the two smoke guide plate assemblies can be opened or closed simultaneously.

[0098] In some examples, the driven component includes a first driven member 61 and a second driven member 62. The first driven member 61 is connected to the lifting component, the first driven member 61 is detachably connected to the second driven member 62, the first driven member 61 is used to drive the second driven member 62 to move, the second driven member 62 is connected to the connecting rod component, the connecting rod component is connected to the rotating component, the connecting rod component is used to drive the rotating component to rotate, and the rotating component is detachably connected to the rotating arm component, and the rotating component is used to drive the rotating arm component to rotate. With such a setting, the driving force of the second driving mechanism can be derived from the first driving mechanism. That is, the first driving mechanism drives the first driven member 61 to move through the lifting component, so that the first driven member 61 is connected to the second driven member 62, the first driven member 61 drives the second driven member 62 to move, the second driven member 62 drives the connecting rod component to move, the connecting rod component drives the rotating component to rotate, and the rotating component drives the rotating arm component to rotate, so that the smoke guide plate rotates relative to the smoke collecting hood 10.

[0099] It should be noted that in other embodiments, the driving force of the second driving mechanism may not be derived from the first driving mechanism. The second driving mechanism can replace the first driven member 61 and the second driven member 62 with a motor. Or, the second driving mechanism can use four push rod motors to open or close the four smoke guide plates.

[0100] Among them, referring to Figure 9 As shown, the first driven member 61 includes a driven rod 611 and a driven ring 612, and the driven rod 611 is connected to the driven ring 612.

[0101] In some examples, the driven rod 611 and the driven ring 612 can be integrally formed.

[0102] The driven rod 611 of the first driven member 61 can be fixedly connected to the nut of the second lead screw 42 of the lifting component.

[0103] In some examples, the second follower 62 can be a follower column. The follower column has an external thread, and the follower ring 612 of the first follower 61 has an internal thread. After the second lead screw 42 drives the first follower 61 to rise a certain distance along the height direction of the head assembly 100, the internal thread of the first follower 61 contacts the external thread of the follower column, and the first follower 61 can drive the follower column to rotate. When the second lead screw 42 drives the first follower 61 to descend along the height direction of the head assembly 100, the first follower 61 can drive the follower column to rotate in the reverse direction and disengage from the follower column.

[0104] In a possible implementation, the second driving mechanism further includes a second transmission 63, a linkage rod 64, and a plurality of third transmissions. The second follower 62 extends along the height direction of the head assembly 100, the linkage rod 64 extends along the length direction of the head assembly 100, the second follower 62 and the linkage rod 64 are respectively connected to the second transmission 63, the plurality of third transmissions are respectively connected to the linkage rod 64, and the plurality of third transmissions are connected to the connecting rod assembly. With such a setting, the second follower 62 can drive the linkage rod 64 to rotate through the second transmission 63, the linkage rod 64 can drive the connecting rod assembly to move through the plurality of third transmissions, the connecting rod assembly drives the rotating assembly to move, and the rotating assembly drives the swing arm assembly to rotate, so that the smoke guide plate rotates relative to the smoke collecting hood 10.

[0105] Among them, both the second transmission 63 and the third transmission are made of worm gears.

[0106] The connecting rod assembly can include a plurality of push rods and a plurality of synchronizing rods. Each push rod is connected to a third transmission, each push rod moves along the width direction of the head assembly 100, each synchronizing rod is connected to a push rod, and the plurality of synchronizing rods are connected to the rotating assembly. With such a setting, the rotating assembly is driven to move through the plurality of synchronizing rods, so that each smoke guide plate assembly is closed or opened simultaneously.

[0107] In a possible implementation, the rotating assembly includes a plurality of rotating members. Each synchronizing rod is connected to two rotating members, and each rotating member is detachably connected to a swing arm. The rotating member is used to drive the swing arm to rotate. With such a setting, during the rotation of the rotating member, the rotating member can drive the swing arm to rotate, so that the smoke guide plate rotates relative to the smoke collecting hood 10.

[0108] Among them, the swing arm has a connection hole 55 (see Figure 7 shown). The rotating member has a rotating column.

[0109] In some examples, the rotating column extends along the height direction of the machine head assembly 100. When the rotating arm rises a certain distance along the height direction of the machine head assembly 100, the rotating column of the rotating member can be inserted into the connecting hole 55 of the rotating arm, so that the rotating member can drive the rotating arm to rotate. When the rotating arm descends along the height direction of the machine head assembly 100, the rotating column of the rotating member can be disengaged from the connecting hole 55 of the rotating arm, realizing the separation of the rotating member and the rotating arm.

[0110] See Figure 10 As shown, the rotating member further has a linkage arm 85. The extending direction of the linkage arm 85 is perpendicular to the extending direction of the rotating column, and the linkage arm 85 is fixedly connected to the rotating column. The linkage arm 85 is rotatably connected to the synchronizing rod.

[0111] In some examples, the synchronizing rod extends along the length direction of the machine head assembly 100. When the push rod drives the synchronizing rod to move along the width direction of the machine head assembly 100, the synchronizing rod can drive the rotating column to rotate through the linkage arm 85.

[0112] In some examples, the second driving mechanism includes two third transmitters. The two third transmitters are respectively the transmitter four 65 and the transmitter five 66 (see Figure 4 and Figure 5 as shown).

[0113] The connecting rod assembly can include two push rods and two synchronizing rods. The two push rods are respectively the first push rod 71 and the second push rod 72. The two synchronizing rods are respectively the first synchronizing rod 73 and the second synchronizing rod 74. The first push rod 71 is connected between the transmitter four 65 and the first synchronizing rod 73. The second push rod 72 is connected between the transmitter five 66 and the second synchronizing rod 74.

[0114] The rotating assembly includes four rotating members. See Figure 11 As shown, the four rotating members are respectively the first rotating member 81, the second rotating member 82, the third rotating member 83 and the fourth rotating member 84.

[0115] The linkage arms 85 of the first rotating member 81 and the second rotating member 82 are respectively rotatably connected to both ends of the first synchronizing rod 73. The rotating column of the first rotating member 81 can be inserted into the connecting hole 55 of the first rotating arm 51. The rotating column of the second rotating member 82 can be inserted into the connecting hole 55 of the second rotating arm 52.

[0116] The linkage arms 85 of the third rotating member 83 and the fourth rotating member 84 are respectively rotatably connected to both ends of the second synchronizing rod 74. The rotating column of the third rotating member 83 can be inserted into the connecting hole 55 of the third rotating arm 53. The rotating column of the fourth rotating member 84 can be inserted into the connecting hole 55 of the fourth rotating arm 54.

[0117] In the integrated stove according to the embodiment of the present invention, since it includes the machine head assembly 100 in the foregoing embodiment, the oil fume suction efficiency can be improved without changing the air intake volume.

[0118] Among them, when the integrated stove is working, the driving motor 31 rotates forward, driving the transmission shaft 32 to rotate, so that the first transmission 33, the second transmission 34, the third transmission 35, the first lead screw 41, the second lead screw 42 and the third lead screw 43 work. The first bracket 44 drives the first smoke guide plate 21 through the first rotating arm 51, the second bracket 45 drives the fourth smoke guide plate 24 through the fourth rotating arm 54, and the second bracket 46 drives the second smoke guide plate 22 and the third smoke guide plate 23 through the second rotating arm 52 and the third rotating arm 53, so that the first smoke guide plate 21, the second smoke guide plate 22, the third smoke guide plate 23 and the fourth smoke guide plate 24 rise simultaneously in the +Z direction until the first rotating arm 51 is connected to the rotating column of the first rotating member 81, the second rotating arm 52 is connected to the rotating column of the second rotating member 82, the third rotating arm 53 is connected to the rotating column of the third rotating member 83, and the fourth rotating arm 54 is connected to the rotating column of the fourth rotating member 84. At the same time, the driven ring 612 of the first driven member 61 is threadedly connected to the second driven member 62, driving the second driven member 62 to rotate. The second transmission 63 can convert the rotation in the Z direction into the rotation in the X direction. The second transmission 63 drives the fourth transmission 65 and the fifth transmission 66 through the linkage rod 64. The fourth transmission 65 and the fifth transmission 66 can convert the rotation in the X direction into the rotation in the Y direction. The fourth transmission 65 drives the first push rod 71, and the fifth transmission 66 drives the second push rod 72. The first push rod 71 and the second push rod 72 move simultaneously in the +Y direction. The first push rod 71 drives the first synchronizing rod 73, the second push rod 72 drives the second synchronizing rod 74. The first synchronizing rod 73 drives the first rotating member 81 and the second rotating member 82 to rotate, and the second synchronizing rod 74 drives the third rotating member 83 and the fourth rotating member 84 to rotate. The first rotating member 81 drives the first rotating arm 51 to rotate along the first guide shaft 14, the second rotating member 82 drives the second rotating arm 52 to rotate along the second guide shaft 15, the third rotating member 83 drives the third rotating arm 53 to rotate along the second guide shaft 15, and the fourth rotating member 84 drives the fourth rotating arm 54 to rotate along the fourth guide shaft 17, so as to realize the simultaneous opening of the first smoke guide plate 21, the second smoke guide plate 22, the third smoke guide plate 23 and the fourth smoke guide plate 24. When the integrated stove is used up, the driving motor 31 rotates reversely, so that the first smoke guide plate 21, the second smoke guide plate 22, the third smoke guide plate 23 and the fourth smoke guide plate 24 descend simultaneously in the -Z direction. At the same time, the first driven member 61 drives the second driven member 62 to rotate reversely, so that the first smoke guide plate 21, the second smoke guide plate 22, the third smoke guide plate 23 and the fourth smoke guide plate 24 are closed simultaneously. Then, the first driven member 61 is disengaged from the second driven member 62, and the first smoke guide plate 21, the second smoke guide plate 22, the third smoke guide plate 23 and the fourth smoke guide plate 24 continue to descend.

[0119] It should be noted that the rotation in the Z direction means that the axis of rotation extends along the Z direction. The rotation in the X direction means that the axis of rotation extends along the X direction. The rotation in the Y direction means that the axis of rotation extends along the Y direction.

[0120] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
