[0047] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0048] The present embodiment provides a range hood head, which can be applied to an integrated stove to achieve smoke collection during the fume extraction process, improve the smoke collection effect, enhance the fume extraction capacity of the integrated stove, and at the same time improve the safety of use of the range hood head and the integrated stove.

[0049] like Figures 1 to 4 As shown, the hood head includes a hood body and a flap mechanism. The hood body has a connected smoke collecting chamber 16 and a smoking port, and the smoking port is arranged at the front side of the hood body. The flap mechanism includes a flap assembly 2 and a flap driving mechanism 3, and the flap driving mechanism 3 includes a linear driving member 31 and a driving rod 32. The lower end of the linear driving member 31 is hinged to the hood body through a lower hinge shaft 34, the lower end of the driving rod 32 is connected to the telescopic part of the linear driving member 31, and the upper end of the driving rod 32 is connected to the upper part of the flap assembly 2 through an upper hinge shaft 33, so that the linear driving member 31 drives the flap assembly 2 through the driving rod 32 to switch between the state of opening the smoking port and the closed state of closing the smoking port.

[0050] When the hood head is not in use, the flap assembly 2 is in a closed state, and the flap assembly 2 closes the smoking port to prevent the odor inside the hood head from escaping out through the smoking port, and makes the overall appearance of the hood head simple and beautiful, so as to improve the appearance and cleaning convenience of the hood head and the integrated stove; when the hood head is in use, the linear drive member 31 drives the drive rod 32 to extend upward to push the flap assembly 2 upward, and flip the flap assembly 2 to open the smoking port, so that the oil smoke can enter the smoke collection chamber 16 through the smoking port, and the flap assembly 2 can stop the oil smoke from escaping upward, thereby enhancing the smoke collection effect; when the flap assembly 2 needs to be closed, the linear drive member 31 drives the drive rod 32 to move downward, so that the drive rod 32 pulls the flap assembly 2 to close the smoking port.

[0051] It is worth noting that the directional descriptions such as "front", "back", "left" and "right" in the previous and following texts are based on the position of the range hood head relative to the operator when it is in use, that is, the side of a structure close to the operator is the front side, the side away from the operator is the back side or dorsal side, the side close to the left hand of the operator facing the range hood head is the left side, and the side close to the right hand of the operator facing the range hood head is the right side.

[0052] In order to protect the linear drive member 31, in this embodiment, the hood head further includes an oil-proof cover 4, which is located in the smoke collecting cavity 16 and is surrounded by the rear cavity wall and the top cavity wall of the smoke collecting cavity 16 to form an oil-proof space, and the linear drive member 31 is installed in the oil-proof space, and the drive rod 32 passes through the rod opening 411. The lower end of the oil-proof cover 4 is detachably connected to the hood body, and the upper end of the oil-proof cover 4 is pluggably connected to the top cavity wall.

[0053] The hood head provided in the present embodiment can reduce the influence of oil smoke on the linear drive member 31 and ensure the reliability of the use of the linear drive member 31 by setting the oil-proof hood 4 and setting the linear drive member 31 in the oil-proof hood 4; the oil-proof hood 4 is formed by enclosing the rear side cavity wall and the top cavity wall of the smoke collecting cavity 16 to form an oil-proof space, so that the oil-proof hood 4 can be a hood structure with a rear opening and a top opening, which simplifies the structure of the oil-proof hood 4 and reduces the difficulty of processing the oil-proof hood 4; the lower end of the oil-proof hood 4 is detachably connected to the hood body, and the upper end of the oil-proof hood 4 is plug-in connected to the top cavity wall, so that when the hood is disassembled, the oil-proof hood 4 can be easily removed. When removing the oil-proof cover 4, it is only necessary to remove the connection structure between the oil-proof cover 4 and the lower end of the range hood body, and then the oil-proof cover 4 can be disassembled and assembled by pulling the oil-proof cover 4 away from the top cavity wall, thereby improving the convenience of disassembly and assembly of the oil-proof cover 4, thereby improving the convenience of loading and unloading and maintenance of the linear drive component 31; and because the rod through-hole 411 is opened at the upper edge of the oil-proof cover 4, the flap mechanism of the oil-proof cover 4 can be kept fixed during disassembly and assembly, thereby further simplifying the disassembly and assembly of the oil-proof cover 4; furthermore, the upper and lower ends of the oil-proof cover 4 are connected to the range hood body, which can effectively ensure the installation stability of the oil-proof cover 4 on the range hood body.

[0054] The range hood body comprises a head frame 1 and a smoke guide plate assembly 6. The head frame 1 has a smoke collecting chamber 16 with an open front side. The smoke guide plate assembly 6 is detachably arranged on the front side of the head frame 1 and closes the lower opening of the smoke collecting chamber 16. A smoking port is formed between the top of the head frame 1 and the upper end of the smoke guide plate assembly 6. The lower end of the oil proof cover 4 is located on the rear side of the smoke guide plate assembly 6. This arrangement allows the head frame 1 and the smoke guide plate assembly 6 to be processed and assembled separately, which is beneficial to the processing of the smoke machine body and easy to control the shape of the smoke chamber 16 and the size of the smoking port. The head frame 1 and the smoke guide plate assembly 6 can be made of different materials, which is beneficial to the cleaning of the smoke machine head and improves the aesthetics of the smoke machine body. Furthermore, since the smoke guide plate assembly 6 is detachably connected to the head frame 1, when the linear drive component 31 is damaged and the flap assembly 2 is closed and cannot be opened, the smoke guide plate assembly 6 can be removed to expose the lower end of the motor cover, and the motor cover can be disassembled and assembled, so that the linear drive component 31 can be inspected and maintained, thereby improving the convenience of inspection and maintenance of the linear drive component 31 and further improving the reliability of the smoke machine head.

[0055] In the present embodiment, the front side surface of the oil proof hood 4 is spaced apart from the smoke guide plate assembly 6, thereby allowing a flow gap for the oil smoke to pass through between the front side of the oil proof hood 4 and the rear side of the smoke guide plate assembly 6, so that the smoke can obtain a larger turning radius when passing over the upper end of the smoke guide plate assembly 6, making the smoke flow smoother and reducing the probability of vortex generation, thereby reducing the resistance to the smoke flow, improving the oil smoke extraction effect, and reducing operating noise.

[0056] When the flap assembly 2 is in a closed state, the front side of the flap assembly 2 is flush with the front side of the smoke guide plate assembly 6, that is, the flap assembly 2 and the smoke guide plate assembly 6 are spliced ​​up and down, so that the overall appearance of the hood head is simple and easy to clean. When the flap assembly 2 is in an open state, the flap assembly 2 extends forward from top to bottom, so that the head frame 1, the smoke guide plate assembly 6 and the flap assembly 2 are surrounded to form a C-shaped negative pressure area, the open radiation surface of which can envelop the oil smoke area and block the upper body of the cook, forming high and low negative pressure areas, wherein the high negative pressure area is formed near the upper end of the smoke guide plate assembly 6, and the low negative pressure area is formed at the C-shaped negative pressure area formed by the head frame 1, the smoke guide plate assembly 6 and the flap assembly 2. When the oil smoke rises to the high negative pressure area, most of the oil smoke can be instantly sucked into the smoke collecting chamber 16 from above the smoke guide plate assembly 6, and a small part of the oil smoke enters the C-shaped negative pressure area due to its large rising force. At this time, the oil smoke transitions to the inside of the smoke collecting chamber 16 along the flap assembly 2, the top cavity wall of the smoke collecting chamber 16, and the rear cavity wall of the smoke collecting chamber 16, thereby improving the smoke collecting effect of the range hood head and the integrated stove.

[0057] In this embodiment, when the flap assembly 2 is in the open state, the angle of the flap assembly 2 relative to the vertical plane is 50° to 70°, so as to increase the range of the oil smoke envelope, improve the smoothness of the oil smoke passing through the C-shaped negative pressure area into the smoke collecting chamber 16, and improve the smoke collecting effect. When the flap assembly 2 is in the open state, the distance between the lower end of the flap assembly 2 and the plane where the outer side of the smoke guide plate assembly 6 is located is 240mm to 300mm, which can effectively block the noise generated by a part of the smoking port while meeting the smoking effect, so as to reduce the noise transmitted to the human ear, thereby reducing the noise during cooking and improving the user experience.

[0058] The head frame 1 includes a back plate 12, a top beam 11 connected to the top of the back plate 12, two side frames 13 connected to the left and right sides of the back plate 12, and a bottom frame assembly 14 connected to the lower end of the back plate 12, and the left and right ends of the bottom frame assembly 14 are respectively connected to the two side frames 13. The back plate 12, the top beam 11, the bottom frame assembly 14 and the two side frames 13 together form a smoke collecting chamber 16, that is, the front side of the back plate 12 forms the rear side cavity wall of the smoke collecting chamber 16, and the lower side of the top beam 11 forms the upper end cavity wall of the smoke collecting chamber 16. The bottom surface of the bottom frame assembly 14 is provided with a smoke exhaust port 141, which is connected to the smoke collecting chamber 16 to exhaust the oil smoke into the air duct inside the integrated stove.

[0059] The lower end of the smoke guide plate assembly 6 is butted against the bottom frame assembly 14, and the left and right sides of the smoke guide plate assembly 6 are mounted on the front sides of the two side frames 13. The left and right sides of the smoke guide plate assembly 6 are preferably aligned with the left and right outer sides of the two side frames 13 to improve the appearance of the head frame 1 and the smoke machine head. The oil-proof cover 4 and the flap drive mechanism 3 are mounted on the front side of the back plate 12.

[0060] The top beam 11 has a top plate portion 111 that forms the top wall of the smoke collecting chamber 16, and the upper end of the oil-proof cover 4 abuts against the top plate portion 111. In this embodiment, the top beam 11 also includes a round beam portion 112, the axis of which extends in the left-right direction, and the round beam portion 112 has a rear end and a front end in the circumferential direction, the rear end is connected to the back plate 12, and the front end is connected to the top plate portion 111. The arrangement of the round beam portion 112 makes the top of the head frame 1 present an arc surface structure, making the entire smoke machine head smooth and simple in appearance, and highly aesthetic; at the same time, the rear end running track of the flap assembly 2 is an arc shape, and the arrangement of the round beam portion 112 is conducive to providing avoidance for the rear end of the flap assembly 2, and improving the coordination between the top beam 11 and the flap assembly 2.

[0061] The top plate 111 preferably extends backwards from top to bottom and the rear end is butted with the back plate 12, so that the top plate 111 can better guide the smoke to flow from the inner side of the flap assembly 2 to the smoke collecting chamber 16, thereby improving the smoke collecting effect of the smoke machine head. In this embodiment, the angle between the top cavity wall and the rear cavity wall is 120° to 150°, that is, the angle between the top plate 111 and the back plate 12 is preferably 120° to 150°.

[0062] In this embodiment, a top space extending left and right is formed inside the top beam 11, and a threading hole 1113 is opened on the top plate portion 111. The power connecting wire of the linear drive member 31 enters the top space of the top beam 11 through the threading hole 1113, and the power connecting wire extends horizontally to a side frame 13, and then extends downward along the internal space of the side frame 13 to pass through the range hood head, so as to realize the connection between the power connecting wire and the controller inside the integrated stove.

[0063] The top plate 111 is recessed from front to back to form a top groove 1111, which is located in the oil-proof space and is arranged opposite to the driving rod 32. The top groove 1111 is formed by stamping the top plate 111 backward to form a top pressing profile 1114 at the rear side of the top plate 111, thereby increasing the structural strength and rigidity of the top plate 111, thereby increasing the structural strength and rigidity of the top beam 11, and the top groove 1111 is shielded by the oil-proof cover 4 to avoid exposure of the top groove 1111, thereby improving the overall structural aesthetics and cleaning convenience of the range hood head. The threading hole 1113 is arranged at the bottom of the top groove 1111.

[0064] like Figure 5 and Figure 6 As shown, in order to improve the convenience of plugging and unplugging the oil-proof cover 4 and the top cavity wall, in this embodiment, a bayonet 1112 is provided on the top cavity wall, and a card plate portion 43 is provided on the top of the oil-proof cover 4. The card plate portion 43 is located on the inner side of the top periphery of the oil-proof cover 4, and the card plate portion 43 is engaged with the bayonet 1112, so that the oil-proof cover 4 is plugged and unplugged and connected with the top cavity wall. By providing the bayonet 1112 on the top cavity wall, the processing difficulty of the top beam 11 can be reduced, and the opening of holes on the surface of the oil-proof cover 4 can be reduced or avoided, so as to ensure the oil-proof performance of the oil-proof cover 4; and through the cooperation of the bayonet 1112 and the card plate portion 43, the stability of the connection between the two can be effectively guaranteed, and the efficiency of disassembly and assembly can be improved; further, the card plate portion 43 is located on the inner side of the top periphery of the oil-proof cover 4, so that the bayonet 1112 is located inside the oil-proof space, further preventing the probability of oil smoke entering the inside of the top beam 11 through the bayonet 1112, and reducing the influence of oil smoke on the internal structure of the top beam 11.

[0065] The oil-proof hood 4 includes a main hood body, which is enclosed with the cavity wall of the smoke-collecting cavity 16 to form an oil-proof space, and a plug-in structure is provided at the upper end of the main hood body, and the plug-in structure includes the above-mentioned card plate portion 43. The plug-in structure includes a top folding edge portion 44 folded inward from the top end of the main hood body, and the end of the top folding edge portion 44 is folded in a direction away from the main hood body to form a card plate portion 43, and the top folding edge portion 44 abuts against the top cavity wall. Thereby reducing the probability of oil smoke entering the oil-proof space from the gap between the upper end of the hood front plate 41 and the upper end of the top plate portion 111.

[0066] In this embodiment, the main cover body includes a cover front plate 41 and cover side plates 42 connected to the left and right sides of the cover front plate 41. The cover front plate 41, the two cover side plates 42 and the head frame 1 together form an oil-proof space, and the cover front plate 41 is provided with the above-mentioned rod opening 411. The structural form of this motor cover makes the cross section of the motor cover U-shaped, while ensuring the installation space of the linear drive member 31 in the motor cover, making the motor cover relatively small in the left and right width directions, reducing the overall size of the motor cover, thereby reducing the effect of the setting of the motor cover on the smoke flow resistance; at the same time, the structure of this motor cover is simple, and it is easy to realize the demoulding process of the motor cover, reducing the processing cost. In other embodiments, the cross section of the motor cover can also be an arc-shaped structure.

[0067] In the present embodiment, the card plate portion 43 is arranged on the cover front plate 41 to ensure the tightness of the fit between the upper front side of the cover front plate 41 and the top plate portion 111. Preferably, the card plate portion 43 is arranged on both the left and right sides of the rod through hole 411. In other embodiments, the card plate portion 43 may be convexly arranged on the top ends of the two cover side plates 42. Preferably, at least the upper side wall of the bayonet 1112 extends upward to form a card hole flange 1115, and the card hole flange 1115 abuts against the card plate portion 43 to increase the contact area between the card plate portion 43 and the top plate portion 111, thereby improving the card connection stability between the card plate portion 43 and the top plate portion 111, and improving the installation reliability of the oil-proof cover 4. In the present embodiment, the card hole flange 1115 is arranged around the bayonet 1112 to increase the structural strength of the top plate portion 111 at the bayonet 1112, and to ensure the matching reliability of the card plate portion 43 and the bayonet 1112.

[0068] like Figures 3 to 5As shown, in order to improve the installation stability of the flap drive mechanism 3 and the oil-proof cover 4 on the head frame 1, a reinforcing beam 15 is installed on the front side of the back plate 12, the oil-proof cover 4 is installed on the front side of the reinforcing beam 15 and encloses the reinforcing beam 15 to form an oil-proof space, the lower end of the oil-proof cover 4 is detachably connected to the reinforcing beam 15, and the lower end of the linear drive member 31 is installed on the reinforcing beam 15 through the driving mounting seat 35. The provision of the reinforcing beam 15 can enhance the structural strength of the connection between the head frame 1 and the linear drive member 31, reduce the probability of deformation of the head frame 1, improve the overall structural strength and rigidity of the head frame 1, and ensure the installation stability of the flap drive mechanism 3 on the head frame 1.

[0069] The reinforcing beam 15 includes a beam main plate portion 151 which is parallel to and spaced from the back plate 12 and two beam side plates 152 connected to the left and right sides of the beam main plate portion 151. The rear edge of the beam side plate portion 152 is folded inward to form a beam folding portion 153. The beam folding portion 153 is in contact with the back plate 12 and is detachably connected, thereby achieving the fastening between the reinforcing beam 15 and the back plate 12, and making the connection structure between the reinforcing beam 15 and the back plate 12 hidden in the rear side of the beam main plate portion 151 and not exposed, thereby improving the structural aesthetics and cleaning convenience of the head frame 1. The reinforcing beam 15 and the back plate 12 are preferably connected by fastening screws to improve the connection stability.

[0070] In order to improve the connection convenience between the oil-proof cover 4 and the reinforcing beam 15, the lower end of the main cover body is fitted with the front side of the reinforcing beam 15, and the left and right sides of the main cover body are extended backward with fixed edges 45, and the two fixed edges 45 are respectively fitted with the left and right sides of the reinforcing beam 15, and the lower ends of the fixed edges 45 are connected to the reinforcing beam 15. This arrangement allows the length of the reinforcing beam 15 to be longer than the length of the main cover body, and ensures that the lower end of the oil-proof space can be closed by the bottom surface of the main cover body; the arrangement of the fixed edges 45 allows the reinforcing beam 15 to be sandwiched between the two fixed edges 45, which is conducive to the connection between the oil-proof cover 4 and the reinforcing beam 15, and ensures the lateral sealing performance of the oil-proof space.

[0071] Furthermore, a fixing through hole is provided at the lower end of the fixing edge 45, a fixing threaded hole is provided on the reinforcing beam 15, the fixing through hole and the fixing threaded hole are aligned, and a cover fastener is passed through the fixing through hole and the fixing threaded hole to fasten the reinforcing beam 15 and the motor cover. The cover fastener is located at the rear side of the smoke guide plate assembly 6 to prevent the cover fastener from being exposed.

[0072] In this embodiment, the reinforcing beam 15 extends in the vertical direction, the lower end of the reinforcing beam 15 extends to abut against the bottom frame assembly 14, and the upper end of the reinforcing beam 15 extends to the top beam 11, thereby increasing the length of the reinforcing beam 15, thereby enhancing the structural strength of the entire head frame 1. In other embodiments, the reinforcing beam 15 can also extend in the left-right direction, and the two ends of the reinforcing beam 15 are respectively connected to the two side frames 13.

[0073] In this embodiment, the reinforcing beam 15 is arranged in the middle of the back plate 12 along the length direction, so that the flap driving mechanism 3 can be installed in the center, thereby better ensuring the force stability and operation reliability of the flap assembly 2.

[0074] A socket is provided on the lower side of the top plate 111. The upper end of the reinforcing beam 15 passes through the socket and extends into the top space of the top beam 11. The shape of the socket is consistent with the cross-sectional shape of the reinforcing beam 15 to achieve the installation and positioning of the reinforcing beam 15 and the top beam 11. The upper edge of the socket is folded outward to form a folding plate 113. The folding plate 113 is fitted and connected to the front side of the reinforcing beam 15 to ensure the installation stability of the reinforcing beam 15. The folding plate 113 is located inside the oil shield 4. This arrangement makes the connection between the reinforcing beam 15, the back plate 12 and the top beam 11 more tightly, ensures the structural rigidity of the entire head frame 1, and reduces the probability of deformation of the head frame 1.

[0075] Furthermore, the front side of the beam main plate portion 151 is recessed backward to form a mounting groove 1511, and a drive mounting seat 35 is arranged in the mounting groove 1511. The lower end of the linear drive member 31 is rotatably mounted on the drive mounting seat 35 through the lower hinge shaft 34. By recessing the mounting groove 1511 from front to back, the back of the beam main plate portion 151 can form a profiled structure at the same time, so as to enhance the overall structural strength and rigidity of the beam main plate portion 151 and reduce the probability of deformation of the beam main plate portion 151; at the same time, the drive mounting seat 35 is arranged in the mounting groove 1511, and the lower end of the linear drive member 31 is installed on the drive mounting seat 35, so that the mounting groove 1511 can avoid part of the structure of the flap drive mechanism 3, thereby improving the overall structural compactness of the smoke machine head, so that the linear drive member 31 can be arranged further away from the smoke guide plate assembly 6, so that the oil protection cover 4 can be further away from the smoke guide plate assembly 6.

[0076] Preferably, the spacing between the main beam portion 151 and the back plate 12 is 5 mm to 12 mm, so as to avoid the overall structural rigidity of the reinforcing beam 15 being reduced due to the spacing being too large, and to avoid the smoke chamber 16 occupying too much space due to the spacing being too large.

[0077] like Figure 5 and Figure 7 As shown, in order to prevent oil smoke from entering the oil-proof space through the rod opening 411, an oil-proof sealing sleeve 8 is provided at the rod opening 411. The oil-proof sealing sleeve 8 includes a sealing ring portion and a sealing membrane portion connected to the inner side of the sealing ring portion. The sealing ring portion is installed at the edge of the hole of the rod opening 411, and a slit is provided on the sealing membrane portion for the drive rod 32 to extend out movably, so as to ensure that the drive rod 32 can rotate a certain stroke in the oil-proof sealing sleeve 8 while allowing the sealing membrane portion to always wrap the drive rod 32, thereby reducing the probability of oil smoke entering the oil-proof space through the connection between the oil-proof sealing sleeve 8 and the drive rod 32.

[0078] In this embodiment, the rod through hole 411 passes through the upper edge of the oil-proof cover 4. This arrangement allows the oil-proof cover 4 to be disassembled and assembled separately on the basis of the flap driving mechanism 3 remaining stationary, thereby improving the convenience of disassembling and assembling the oil-proof cover 4 and, at the same time, also improving the convenience of disassembling and assembling the oil-proof sealing sleeve 8 on the oil-proof cover 4.

[0079] The sealing ring part has an overall U-shaped structure, and the hole edge of the rod through hole 411 is a U-shaped edge with the opening facing upward. The shape of the sealing ring part is adapted to the shape of the U-shaped edge to improve the convenience of disassembly and assembly between the oil-proof sealing sleeve 8 and the oil-proof cover 4. The outer wall of the sealing ring part is provided with a slot, which is consistent with the shape of the hole edge of the rod through hole 411, and the hole edge is inserted into the slot to realize the installation of the oil-proof sealing sleeve 8 on the oil-proof cover 4. It is worth noting that the specific structure of the oil-proof sealing sleeve 8 and the matching structure of the oil-proof sealing sleeve 8 and the oil-proof cover 4 can be set with reference to the prior art. This is not the focus of the present utility model and will not be repeated here.

[0080] In order to improve the installation convenience of the oil-proof sealing sleeve 8 on the oil-proof hood 4, the top of the hood front plate 41 is recessed backward to form an avoidance groove 412, and the bottom of the avoidance groove 412 is provided with the above-mentioned rod through-hole 411, and the oil-proof sealing sleeve 8 is installed in the avoidance groove 412. The setting of the avoidance groove 412 can prevent the front side of the oil-proof sealing sleeve 8 from protruding from the front side of the hood front plate 41, and can improve the overall structural aesthetics of the range hood head. The rear end of the avoidance groove 412 is spaced apart from the top plate 111, and the rear end of the oil-proof sealing sleeve 8 abuts against the top plate 111, so that the slot on the oil-proof sealing sleeve 8 is an annular groove with both ends closed, thereby facilitating the sealing between the hood front plate 41 and the top plate 111.

[0081] like Figure 2 As shown, in order to improve the performance of the range hood head and the integrated stove, a lighting lamp 7 is installed on the top plate portion 111, and one lighting lamp 7 is arranged on the left and right sides of the oil-proof cover 4 to achieve lighting during cooking.

[0082] In order to further improve the smoke collecting effect of the hood head, the hood head further includes a side baffle assembly 5, which is provided at each of the left and right ends of the flap assembly 2, and the side baffle assembly 5 can be unfolded when the flap assembly 2 is opened and folded when the flap assembly 2 is closed. When the flap assembly 2 is in the open state, the front end of the side baffle assembly 5 is connected to the flap assembly 2, and the rear end of the side baffle assembly 5 is located at the rear side of the front side of the side frame 13.

[0083] By providing a side baffle assembly 5 that can be expanded and folded with the flap assembly 2, when the flap assembly 2 is opened, the side baffle assembly 5 can be expanded to close the side of the upper smoke collecting chamber 16, thereby reducing the probability of oil smoke escaping to the left and right sides, improving the smoking effect, and thus improving the smoke collecting effect of the range hood head; at the same time, the side baffle assembly 5 can be folded as the flap assembly 2 is closed, so that the expanded area of ​​the side baffle assembly 5 when the flap assembly 2 is opened can meet the lateral smoke blocking effect while reducing the space occupied by the side baffle assembly 5 after the flap assembly 2 is closed, so that when the flap assembly 2 is in a closed state, the side baffle assembly 5 can be completely accommodated between the flap assembly 2 and the back panel 12, and the thickness requirement for the range hood head is reduced, thereby improving the structural compactness of the range hood head.

[0084] In this embodiment, the structure of the side baffle assembly 5 can be set with reference to the prior art, which is not the focus of this embodiment and will not be described here. This embodiment also provides an integrated stove, including the above-mentioned hood head. The integrated stove provided in this embodiment, by adopting the above-mentioned hood head, can improve the oil fume extraction effect of the integrated stove, reduce the noise during the operation of the integrated stove, improve the operating stability and use safety of the integrated stove, and improve the user experience of the integrated stove.
