Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to a range hood head and an integrated stove. Background Art

[0002] An integrated stove is a common kitchen appliance that combines cooking, fume extraction and lighting functions. It integrates multiple kitchen appliances to reduce the space occupied by kitchen appliances and improve the convenience of setting up and using kitchen appliances.

[0003] The integrated stove is equipped with a hood head at the rear of the gas stove. Figure 1 and Figure 2 As shown, the smoke machine head includes a machine head frame 100, a smoke guide plate 300 arranged on the front side of the machine head frame 100, and a flap 200 rotatably mounted on the front side of the machine head frame 100. A push rod motor 400 is arranged inside the machine head frame 100. The lower end of the push rod motor 400 is hinged to the back plate 101 of the machine head frame 100 and the upper end is hinged to the flap 200. When the push rod 401 of the push rod motor 400 is extended, the flap 200 is pushed to flip forward to open the smoke inlet; when the push rod 401 of the push rod motor 400 is retracted downward, the machine head flap 200 is pulled to flip backward to close the smoke inlet.

[0004] In the hood head provided by the prior art, since the lower end of the push rod motor 400 is hinged to the back plate 101, and the upper end is hinged to the upper end of the back side of the flap 200, when the push rod motor 400 is in the closed state, the push rod motor 400 extends forward from bottom to top and the tilt angle of the push rod motor 400 is usually large (about 8° to 15°). As the flap 200 is opened, the push rod 401 of the push rod motor 400 extends upward, and the upper end of the push rod motor 400 moves forward synchronously, so that the forward tilt angle of the push rod motor 400 is further increased. The forward-inclined setting of the push rod motor 400 causes the reaction force of the flap 200 acting on the push rod motor 400 to generate a lateral component force pointing horizontally backward and a vertical component force pointing vertically downward, and the greater the inclination angle of the push rod motor 400 relative to the vertical direction, the greater the lateral component force. The existence of the lateral component force will cause extrusion at the connection between the push rod 401 and the main structure 402 of the push rod motor 400. Since the structure of the connection is relatively weak, it is easy to cause the push rod 401 or the main structure 402 to bend and deform, affecting the service life of the push rod motor 400 and the operational reliability of the flap 200, and even unable to work normally in severe cases; at the same time, since the push rod 401 and the main structure 402 squeeze each other, abnormal noise is generated when the push rod 401 is extended and retracted, increasing the operating noise of the push rod motor 400, thereby causing the range hood head and the integrated stove to operate with greater noise, affecting the use of the integrated stove.

[0052] Embodiment 1

[0053] 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.

[0054] like Figures 3 to 6As shown, the smoke machine head includes a machine head body, a flap assembly 2 and a flap drive mechanism 3. Specifically, the machine head body has a connected smoke collecting chamber 16 and a smoke inlet, and the smoke inlet is arranged on the front side of the machine head body. The flap assembly 2 has a closed state in which the smoke inlet is closed and an open state in which the smoke inlet is opened; the flap drive mechanism 3 includes a linear drive member 31 and a drive rod 32, the lower end of the linear drive member 31 is hinged to the machine head body through a lower hinge shaft 34, the lower end of the drive rod 32 is connected to the telescopic part 311 of the linear drive member 31, and the upper end of the drive rod 32 is connected to the upper part of the flap assembly 2 through an upper hinge shaft 33, so that the linear drive member 31 drives the flap assembly 2 to switch between the open state and the closed state through the drive rod 32.

[0055] When the hood head is not in use, the flap assembly 2 is in a closed state, and the flap assembly 2 closes the smoke inlet to prevent the odor inside the hood head from escaping out through the smoke inlet, 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 smoke inlet, so that the oil smoke can enter the smoke collection chamber 16 through the smoke inlet, 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 smoke inlet.

[0056] In this embodiment, the drive rod 32 is bent so that when the flap assembly 2 is in a closed state, the linear drive member 31 is vertically arranged, or the linear drive member 31 extends forward from bottom to top, and the angle between the linear drive member 31 and the vertical direction is less than or equal to 5°.

[0057] The range hood head provided in the present embodiment, through the bending setting of the driving rod 32, allows the linear driving member 31 to be vertically set or tilted forward at a small angle relative to the vertical direction when the flap assembly 2 is closed, thereby avoiding or reducing the horizontal lateral component of the force applied to the linear driving member 31 by the flap assembly 2, thereby reducing the probability of the telescopic component 311 and the driving rod 32 being damaged by the force, thereby increasing the service life of the flap driving mechanism 3, and at the same time reducing the extrusion between the telescopic component 311 and the main body component 312, thereby reducing the abnormal sound during the operation of the linear driving member 31, thereby reducing the noise during the operation of the range hood head; furthermore, since the linear driving member 31 is flush with the vertical direction or tilted at a small angle relative to the vertical direction when the flap is closed, the tilt angle of the linear driving member 31 can be reduced when the flap assembly 2 is opened, thereby increasing the distance between the linear driving member 31 and the smoke inlet, thereby reducing the influence of the setting of the flap driving mechanism 3 on the resistance during the oil fume extraction, thereby ensuring the oil fume extraction effect.

[0058] 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.

[0059] The machine head body includes a machine head frame 1 and a smoke guide plate assembly 6. The machine 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 machine head frame 1 and closes the lower opening of the smoke collecting chamber 16. A smoke inlet is formed between the top of the machine head frame 1 and the upper end of the smoke guide plate assembly 6. The lower end of the linear drive member 31 is located at the rear side of the smoke guide plate assembly 6. This arrangement allows the machine head frame 1 and the smoke guide plate assembly 6 to be processed and assembled separately, which is conducive to processing the machine head body, and it is easy to control the shape of the smoke collecting chamber 16 and the size of the smoke inlet. The machine head frame 1 and the smoke guide plate assembly 6 can be made of different materials, which is conducive to cleaning the smoke machine head and improving the aesthetics of the machine head body.

[0060] 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 smoke machine 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 machine head frame 1, the smoke guide plate assembly 6 and the flap assembly 2 are surrounded to form a C-shaped negative pressure area, and its open radiation surface can envelop the oil smoke area and block the upper body of the human body, 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 machine 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 interior of the smoke collecting chamber 16 along the flap assembly 2, the top wall of the smoke collecting chamber 16, and the rear wall of the smoke collecting chamber 16, thereby improving the smoke collecting effect of the range hood head and the integrated stove.

[0061] 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 part of the noise generated by the smoke inlet 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.

[0062] For the convenience of description, the upper end of the driving rod 32 is assumed to be the plate hinge end, the lower end of the driving rod 32 is assumed to be the driving connection end, the plate hinge end is hinged to the flap assembly 2 through the upper hinge shaft 33, and the driving connection end is connected to the telescopic component 311. The plane passing through the axis of the upper hinge shaft 33 and the axis of the lower hinge shaft 34 is assumed to be the rotating shaft plane.

[0063] In this embodiment, when the flap assembly 2 is in a closed state, the linear drive member 31 is arranged to be tilted forward from bottom to top, which can ensure that when the linear drive member 31 is initially extended upward, the driving force applied by the linear drive member 31 is tilted upward, that is, the driving force applied by the linear drive member 31 has a forward component, thereby preventing the linear drive member 31 from generating a backward driving component that causes the flap assembly 2 to be unable to flip open, thereby ensuring the smoothness of the flip opening of the flap assembly 2, and at the same time reducing the load applied to the linear drive member 31, thereby improving the operating reliability and stability of the flap drive mechanism 3 and the flap assembly 2.

[0064] When the flap assembly 2 is in the maximum open state, the linear drive member 31 is tilted forward from bottom to top, and the inclination angle of the linear drive member 31 to the vertical direction is 5°~15°, preferably 5°~10°, to avoid the problem that the linear drive member 31 occupies a large space due to the excessive inclination angle and the connection position of the telescopic part 311 and the main part 312 is subjected to large force. At the same time, it can ensure that the linear drive member 31 can be as far away from the smoke guide plate assembly 6 as possible, reduce the influence of the setting of the flap drive mechanism 3 on the oil fume extraction resistance, and improve the smoothness of the oil fume extraction.

[0065] In this embodiment, the linear drive member 31 is a push rod motor, that is, the telescopic rod of the push rod motor is the telescopic component 311, and the structure of the push rod motor other than the telescopic rod forms the main body component 312 of the linear drive member 31. In other embodiments, the linear drive member 31 may also adopt other structures capable of realizing linear drive. The push rod motor or other structures capable of realizing linear drive may adopt existing mature products, and the specific structure of the linear drive member 31 will not be described in detail in this embodiment.

[0066] The driving rod 32 is preferably detachably connected to the telescopic component 311, so that the linear driving component 31 can adopt existing mature products, while the driving rod 32 can be specifically structured according to the model and size of the range hood head, thereby reducing the design and processing costs of the flap driving mechanism 3.

[0067] like Figure 5 and Figure 6 As shown, the driving rod 32 includes a lower rod section 321 and an upper rod section 322. The lower end of the lower rod section 321 is connected to the telescopic component 311, the upper end of the upper rod section 322 is connected to the lower end of the upper rod section 322, the upper end of the lower rod section 321 is hinged to the flap assembly 2, and the lower rod section 321 and the lower rod section 321 are connected to form an obtuse angle with the opening facing forward. This arrangement forms a bending portion between the lower rod section 321 and the upper rod section 322, and the bending portion is located at the rear side of the rotating shaft plane, so that when the angle of the flange assembly is unchanged, the angle of rotation of the linear driving member 31 around the lower hinge shaft 34 is reduced, and then when the flap assembly 2 is opened to a preset angle, the inclination angle of the linear driving member 31 relative to the vertical direction is reduced.

[0068] In this embodiment, the lower rod section 321 includes a driving connecting rod portion 3211 and a lower bending rod portion 3212. The driving connecting rod portion 3211 extends in the same direction as and is connected to the telescopic component 311. The lower bending rod portion 3212 extends backward from bottom to top at an angle. The lower bending rod portion 3212 is connected between the lower end of the upper rod section 322 and the upper end of the driving connecting rod portion 3211.

[0069] By setting a driving connecting rod portion 3211 extending in the same direction as the telescopic component 311, the connection convenience between the driving rod 32 and the telescopic component 311 can be improved, the acting force between the driving connecting rod portion 3211 and the telescopic component 311 can be reduced, and the probability of deformation at the connection between the two can be reduced; by setting a lower bending rod portion 3212 extending obliquely backward from bottom to top, the driving connecting rod segment 323 can be vertically set or obliquely set forward from bottom to top, while the bending portion formed by the upper rod segment 322 and the lower rod segment 321 can be moved backward, thereby increasing the distance between the bending portion and the rotating shaft plane, thereby further reducing the rotation angle of the linear driving component 31 when the flap assembly 2 is opened to a preset angle, thereby reducing the angle between the linear driving component 31 and the vertical plane when the flap assembly 2 is flipped to the maximum opening angle.

[0070] Preferably, when the flap assembly 2 is in a closed state, the angle of the lower bending rod portion 3212 relative to the vertical direction is 15° to 35°.

[0071] In order to improve the connection convenience between the driving connecting rod 3211 and the telescopic component 311, the driving connecting rod 3211 has two fixed arms arranged opposite to each other, and the upper end of the telescopic component 311 is inserted between the two fixed arms and detachably connected to the fixed arms. The telescopic component 311 has two fixed planes arranged opposite to each other, and the two fixed planes are respectively fitted with the two fixed arms to improve the connection reliability between the driving connecting rod 3211 and the telescopic component 311.

[0072] Furthermore, the upper rod section 322 includes an upper bending rod portion 3221 and a plate connecting rod portion 3222, and the upper bending rod portion 3221 and the plate connecting rod portion 3222 both extend forwardly from bottom to top at an angle, and the angle of the upper bending rod portion 3221 relative to the horizontal plane is smaller than the angle of the plate connecting rod portion 3222 relative to the horizontal plane, and the upper bending rod portion 3221 is connected between the upper end of the lower rod section 321 and the plate connecting rod portion 3222, and the front end of the plate connecting rod portion 3222 is hinged to the flap assembly 2.

[0073] The upper bending rod portion 3221 extends upwardly from bottom to top at an angle, so that the driving rod 32 extends upward as a whole and the end can be hinged with the upper part of the flap assembly 2, raising the connection position between the driving rod 32 and the flap assembly 2. The angle between the plate connecting rod portion 3222 and the horizontal plane is smaller than the angle between the upper bending rod portion 3221 and the horizontal plane, so that when the flap assembly 2 is in a closed state, the plate hinge end and the flap assembly 2 can be arranged closer to verticality, thereby reducing the torque applied by the flap assembly 2 to the upper end of the driving rod 32, reducing the probability of bending and deformation of the driving rod 32, and increasing the service life of the driving rod 2. At the same time, it can reduce the reaction force applied by the flap assembly 2 to the driving rod 32, and reduce the probability of damage to the driving rod 32 due to a large load.

[0074] Preferably, the angle between the upper bending rod portion 3221 and the rotation axis plane is greater than 0° and less than or equal to 60°. Further, the angle between the plate connecting rod portion 3222 and the horizontal plane is less than or equal to 30°.

[0075] In other embodiments, the upper rod segment 322 and / or the lower rod segment 321 can be a straight rod structure, that is, the upper end of the upper rod segment 322 is directly hinged to the flap assembly 2, and / or the lower end of the lower rod segment 321 is directly connected to the telescopic component 311.

[0076] In this embodiment, the connection between the rods is connected by a small arc transition, and the connection between the rods forms a distinct corner structure. In other embodiments, the connection between the rods is connected by a larger arc smooth transition, so that the driving rod 32 forms an arc bend at each bending portion, that is, the driving rod 32 does not form a distinct inflection point position at each bending portion or a partial bending portion.

[0077] like Figure 7 and Figure 8As shown, in order to improve the connection convenience between the driving rod 32 and the flap assembly 2, in this embodiment, the flap assembly 2 includes an outer flap 21, an inner connecting plate 22 and a plate hinge seat 23. Among them, the inner connecting plate 22 is attached to the inner side of the outer flap 21, and the plate hinge seat 23 includes a fixed bottom plate 231 and a rotating ear plate portion 232 protruding from the fixed bottom plate 231. The fixed bottom plate 231 is sandwiched between the outer flap 21 and the inner connecting plate 22, and the rotating ear plate portion 232 extends out of the inner connecting plate 22 and is hinged with the plate connecting rod portion 3222 through the upper hinge shaft 33. The outer flap 21 is preferably made of glass or other materials that are easy to clean. The fixed bottom plate 231 is preferably bonded to the inner side of the inner connecting plate 22.

[0078] Two rotating ear plate portions 232 are arranged at intervals along the left-right direction, the plate connecting rod portion 3222 is sandwiched between the two rotating ear plate portions 232, and the upper hinge shaft 33 passes through the two plate connecting rod portions 3222 and the two rotating ear plate portions 232.

[0079] like Figure 4 , Figure 6 and Figure 8 As shown, in order to protect the linear drive component 31, in the present embodiment, the range hood head also includes an oil-proof cover 4, which is installed in the smoke collecting chamber 16 and is combined with the head body to form an oil-proof chamber, and a rod avoidance hole 42 is opened on the front side of the upper end of the oil-proof cover 4, and the upper rod section 322 is inserted into the rod avoidance hole 42.

[0080] 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.

[0081] The front side of the oil-proof cover 4 is recessed backward to form a drainage groove 41, which is set to pass through from left to right and directly faces the upper end of the smoke guide plate assembly 6. By setting the drainage groove 41 directly facing the upper end of the smoke guide plate assembly 6, the distance between the upper end of the smoke guide plate assembly 6 and the oil-proof cover 4 can be increased, thereby further increasing the turning radius of the smoke when passing over the upper end of the smoke guide plate assembly 6, improving the smoothness of the smoke flow, and further improving the effect of oil fume extraction.

[0082] To prevent oil smoke from entering the oil-proof cavity through the rod avoidance hole 42, an oil-proof sealing sleeve 8 is provided at the rod avoidance hole 42. 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 rod avoidance hole 42. The sealing membrane portion is provided with a slit for the drive rod 32 to extend out, 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 cavity through the connection between the oil-proof sealing sleeve 8 and the drive rod 32.

[0083] like Figure 4 As shown, 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 are surrounded to form a smoke collecting chamber 16. The lower end of the smoke guide plate assembly 6 is docked with the bottom frame assembly 14, and the left and right sides of the smoke guide plate assembly 6 are installed on the front side 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. A smoke exhaust port 141 is provided on the bottom surface of the bottom frame assembly 14, and the smoke exhaust port 141 is connected to the smoke collecting chamber 16 to discharge the oil smoke into the air duct inside the integrated stove.

[0084] The flap driving mechanism 3 is installed on the front side of the back plate 12. The top beam 11 has a top plate portion 111 that forms the top wall of the smoke collecting chamber 16. The upper end of the oil-proof hood 4 abuts against the top plate portion 111 so that the top plate portion 111 closes the upper end opening of the oil-proof chamber. There is no need to additionally set a top sealing plate structure on the top of the oil-proof hood 4, which simplifies the overall structure of the range hood head and improves the appearance of the entire range hood head.

[0085] like Figure 8 As shown, in this embodiment, the rod avoidance hole 42 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.

[0086] The sealing ring part has an overall U-shaped structure, and the hole edge of the rod avoidance hole 42 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. A slot is provided on the outer side wall of the sealing ring part, and the slot is consistent with the shape of the hole edge of the rod avoidance hole 42. 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.

[0087] It is worth noting that the specific structure of the oil-proof sealing sleeve 8 and the oil-proof cover 4, and the matching structure of the oil-proof sealing sleeve 8 and the oil-proof cover 4 can be set with reference to the existing technology. This is not the focus of the present utility model and will not be repeated here.

[0088] like Fig.10 and Fig.11 As shown, in the present embodiment, the top beam 11 also includes a circular beam portion 112, the axis of the circular beam portion 112 extends in the left-right direction, the circular 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 setting of the circular beam portion 112 makes the top of the head frame 1 present an arc surface structure, so that the appearance of the entire smoke machine head is smooth and simple, and the appearance is highly aesthetic; at the same time, the rear end running trajectory of the flap assembly 2 is arc-shaped, and the setting of the circular beam portion 112 is conducive to providing avoidance for the rear end of the flap assembly 2, thereby improving the coordination between the top beam 11 and the flap assembly 2.

[0089] The top plate 111 preferably extends backwards from top to bottom and the rear end is butted against 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 hood head. The angle between the top plate 111 and the horizontal plane is preferably 30° to 70°.

[0090] In this embodiment, a wire threading hole 1112 is opened on the top plate portion 111, and the power connecting wire of the linear drive member 31 enters the interior of the top beam 11 through the wire threading hole 1112. The power connecting wire is extended 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.

[0091] The top plate 111 is recessed from front to back to form a top groove 1111, which is located in the oil-proof cavity 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 1113 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 1112 is arranged at the bottom of the top groove 1111.

[0092] In order to improve the installation stability of the flap driving mechanism 3 on the machine 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 is surrounded by the reinforcing beam 15 to form an oil-proof cavity, and the lower end of the linear driving member 31 is installed on the reinforcing beam 15. The provision of the reinforcing beam 15 can enhance the structural strength of the connection between the machine head frame 1 and the linear driving member 31, reduce the probability of deformation of the machine head frame 1, improve the overall structural strength and rigidity of the machine head frame 1, and ensure the installation stability of the flap driving mechanism 3 on the machine head frame 1.

[0093] 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.

[0094] 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 increasing the structural reinforcement effect on 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.

[0095] 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.

[0096] A top insertion hole is provided on the lower side of the top plate portion 111, and the upper end of the reinforcing beam 15 passes through the top insertion hole and extends into the interior of the top beam 11. The shape of the top insertion hole is consistent with the cross-sectional shape of the reinforcing beam 15, so as to realize the installation and positioning of the reinforcing beam 15 and the top beam 11. The upper edge of the top insertion hole is folded outward to form a pressing plate portion 113, which fits and connects with the front side of the reinforcing beam 15 to ensure the installation stability of the reinforcing beam 15. The pressing plate portion 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.

[0097] 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.

[0098] like Fig. 9 As shown, in the present embodiment, the driving mounting seat 35 is fastened by threaded fasteners which are sequentially passed through the back plate 12, the reinforcing beam 15 and the driving mounting seat 35, so that the back plate 12, the reinforcing beam 15 and the driving mounting seat 35 are fastened together, thereby improving the installation stability of the driving mounting seat 35 on the reinforcing beam 15, thereby ensuring the installation stability of the flap driving mechanism 3.

[0099] 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.

[0100] In order to improve the convenience of cooperation between the driving mounting seat 35 and the linear driving member 31, the driving mounting seat 35 includes two seat side plates 351 spaced apart from each other and a seat connecting plate 353 connected between the two seat side plates 351. The lower end of the main body part 312 of the linear driving member 31 extends between the two seat side plates 351, and the lower hinge shaft 34 passes through the lower end of the main body part 312 and the two seat side plates 351. Each seat side plate 351 is folded outward to form a seat fixing plate 352, which abuts against the bottom of the mounting groove 1511, and the threaded fastener passes through the back plate 12, the bottom of the mounting groove 1511 and the seat fixing plate 352 in sequence.

[0101] like Fig.10 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.

[0102] 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.

[0103] 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.

[0104] 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 in detail here.

[0105] The present embodiment further provides an integrated stove, comprising the above-mentioned range hood head. The integrated stove provided in the present embodiment, by adopting the above-mentioned range 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 operation stability and use safety of the integrated stove, and improve the use experience of the integrated stove.

The basic structure of the range hood head provided in the present embodiment is the same as that of the first embodiment, with only some differences in the settings. The present embodiment will not repeat the same structure as the first embodiment.

[0108] like Fig.12 and Fig.13 As shown, in this embodiment, the driving rod 32 only includes an upper rod section 322 and a lower rod section 321, which are connected to form a V-shaped rod structure, the upper end of the upper rod section 322 is hinged to the flap assembly 2 through the upper hinge shaft 33, the lower rod section 321 is connected to the telescopic component 311, and the extension direction of the lower rod section 321 is the same as the extension direction of the telescopic component 311. In this structure of the driving rod 32, the driving rod 32 has a bending portion, which can simplify the processing of the driving rod 32 and reduce the processing difficulty of the driving rod 32.

[0109] In this embodiment, when the flap assembly 2 is in a closed state, the angle of the linear drive member 31 relative to the vertical direction is greater than or equal to 0° and less than or equal to 3°, so as to reduce the forward tilt angle of the linear drive member 31 when the flap assembly 2 is opened.
