[0052] 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.

[0053] like Figure 1 and Figure 2 As shown, the cigarette machine head comprises a machine head frame 10, a smoke guide plate assembly 30 and a flap mechanism. The machine head frame 10 has a smoke collecting chamber 8 with an open front side, the smoke guide plate assembly 30 is installed on the front side of the machine head frame 10 and closes the lower opening of the smoke collecting chamber 8, and a smoking port is formed between the top of the smoke guide plate assembly 30 and the top of the machine head frame 10; the flap mechanism comprises a flip panel 20 and a flip drive mechanism 40, and the flip drive mechanism 40 is installed on the machine head frame 10 and can drive the flip panel 20 to switch between an open state of opening the smoking port and a closed state of closing the smoking port.

[0054] When the range hood head is not in use, the flip panel 20 is in a closed state, the flip panel 20 closes the smoking port, and the front side surface of the flip panel 20 is flush with the front side surface of the smoke guide plate assembly 30 to prevent the odor inside the range hood head from escaping out through the smoking port, and make the overall appearance of the range hood head simple and beautiful, so as to improve the appearance and cleaning convenience of the range hood head and the integrated stove; when the range hood head is in use, the flip plate driving mechanism 40 drives the flip panel 20 to flip open the smoking port, so that the oil smoke can enter the smoke collection chamber 8 through the smoking port, and the flip panel 20 can stop the oil smoke from escaping upward, thereby enhancing the smoke collection effect.

[0055] like Figure 2 and Figure 3 As shown, the head frame 10 includes a back plate 2, a top beam 6 connected to the top of the back plate 2, two side frames 3 connected to the left and right sides of the back plate 2, and a bottom beam 1 connected to the lower end of the back plate 2, and the left and right ends of the bottom beam 1 are respectively connected to the two side frames 3. The back plate 2, the top beam 6, the bottom beam 1 and the two side frames 3 are surrounded to form a smoke collecting chamber 8. The lower end of the smoke guide plate assembly 30 is connected to the bottom beam 1, and the left and right sides of the smoke guide plate assembly 30 are installed on the front side of the two side frames 3. The left and right sides of the smoke guide plate assembly 30 are preferably aligned with the left and right outer sides of the two side frames 3, respectively, to improve the appearance of the head frame 10 and the smoke machine head. A smoke exhaust port 111 is provided on the bottom surface of the bottom beam 1, and the smoke exhaust port 111 is connected to the smoke collecting chamber 8 to discharge the oil smoke into the air duct inside the integrated stove.

[0056] 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.

[0057] like Figures 2 to 5 As shown, in this embodiment, the bottom beam 1 includes a shell bottom plate 11 vertically connected to the front side of the lower end of the back plate 2, the front side of the shell bottom plate 11 is folded upward to form a front cross beam 12, and the left and right sides of the shell bottom plate 11 are folded upward to form side oil retaining flanges 13. The shell bottom plate 11, the front cross beam 12, the back plate 2 and the left and right side oil retaining flanges 13 together form a circumferentially closed oil retaining space, and the smoke exhaust port 111 is located in the oil retaining space.

[0058] The head frame 10 and range hood head provided in the present embodiment form a circumferentially closed oil retaining space by enclosing the shell bottom plate 11, the back plate 2, the front cross beam 12 and the side oil retaining flange 13, so that the oil stains dripping downward from the inner wall of the head frame 10 can drip into the oil retaining space and flow out through the smoke exhaust port 111 inside the oil retaining space, preventing the oil stains from flowing outward through the circumferential edge of the shell bottom plate 11 to the outside of the head frame 10, thereby alleviating or avoiding the problem of turbulent flow of oil stains inside the head frame 10 and the range hood head, so that the oil stains inside the range hood head will not penetrate into the outside of the body through the joint between the head frame 10 and the integrated stove body, thereby improving the cleaning convenience of the range hood head and the integrated stove, and further improving the user experience of the integrated stove.

[0059] The smoke outlet 111 is a long strip structure extending in the left-right direction to increase the smoothness of smoke exhaust. The periphery of the smoke outlet 111 extends downward to form a mounting flange 15, which is arranged around the smoke outlet 111 and is used to dock with the wind hood inside the body of the integrated stove.

[0060] It is worth noting that the installation structure of the range hood head on the integrated stove can be set up with reference to the existing technology. This is not the focus of the present utility model and will not be described in detail here.

[0061] like Figure 2 and Figure 3 As shown, in order to improve the installation stability of the flap drive mechanism 40 on the head frame 10, the head frame 10 also includes a reinforcing beam 7, which is installed on the front side of the back plate 2, and the flap drive mechanism 40 is installed on the reinforcing beam 7. Therefore, the overall structural strength and rigidity of the head frame 10 are improved by the setting of the reinforcing beam 7, and the supporting performance of the head frame 10 for the flap drive mechanism 40 is improved, and the probability of deformation of the connection between the head frame 10 and the flap drive mechanism 40 is reduced, thereby reducing the probability of vibration of the flap drive mechanism 40 and the head frame 10 during use, and reducing the noise of the range hood head and the integrated stove.

[0062] The flip panel driving mechanism 40 is preferably arranged in the middle of the head frame 10 in the left-right direction, thereby improving the force balance of the flip panel 20, thereby improving the operation reliability of the flip panel 20. The reinforcing beam 7 preferably extends in the vertical direction, and the lower end of the reinforcing beam 7 preferably extends to the shell bottom plate 11, and the upper end of the reinforcing beam 7 preferably extends to the top beam 6, so as to further enhance the structural strength and rigidity of the head frame 10.

[0063] The specific structure of the flip plate driving mechanism 40 and the flip panel 20 and the specific installation structure on the head frame 10 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.

[0064] like Figure 2 and Figure 6As shown, in this embodiment, the top beam 6 has a top space inside, which extends in the left-right direction, and the side frame 3 has a side space inside, which extends in the vertical direction. A threading hole is provided on the top beam 6, and the connecting wires of the flap driving mechanism 40 enter the top space through the threading hole and pass downward through the side space to the head frame 10, so that the connecting wires can be electrically connected to the controller inside the integrated stove.

[0065] Furthermore, in this embodiment, a lighting lamp 50 is installed at the top beam 6, and the wiring of the lighting lamp 50 also passes through the top space and the side space and then extends downward from the head frame 10 to achieve electrical connection between the lighting lamp 50 and the controller. In other embodiments, a temperature sensing module or other detection components can also be installed on the top beam 6, that is, the wiring of the electrical components installed on the top beam 6 can pass through the top space and the side space downward and out of the head frame 10 in turn. This embodiment does not limit the type, quantity and installation structure of the electrical components installed on the top beam 6.

[0066] In order to improve the regularity of the routing of the connecting wires, the lower end of the side frame 3 has a frame bottom plate 311, and a routing hole 3111 is opened on the frame bottom plate 311. The routing hole 3111 is located outside the oil retaining space, so that the routing hole 3111 is located outside the oil circuit of the head frame 10 and the range hood head, thereby preventing the oil stains inside the head frame 10 from acting on the connecting wires, ensuring the safety and reliability of the connecting wires, and preventing the oil stains from flowing along the connecting wires to the internal controller of the integrated stove, thereby improving the safety and reliability of the integrated stove.

[0067] like Figure 5 and Figure 6 As shown, in order to increase the probability of reducing the oil in the oil retaining space from flowing into the wiring hole 3111, the side oil retaining flange 13 is inserted into the inside of the side frame 3, so that the lower end of the inner wall of the side frame 3 facing the other side frame 3 is located inside the oil retaining space, thereby further preventing the oil in the oil retaining space from flowing toward the wiring hole 3111, and also facilitating the assembly positioning between the side frame 3 and the bottom beam 1.

[0068] In order to improve the assembly convenience of the side frame 3 and the bottom beam 1, the left and right sides of the shell bottom plate 11 are provided with avoidance notches 112, and the avoidance notches 112 penetrate the left and right corresponding side edges and the front edge of the shell bottom plate 11. The edge of the avoidance notch 112 is folded upward to form the above-mentioned side oil retaining flange 13, and the shape of the frame bottom plate 311 is the same as the shape of the avoidance notch 112. The frame bottom plate 311 is inserted into the avoidance notch 112 so that the front side edge of the frame bottom plate 311 can be flush with the front side edge of the shell bottom plate 11, and the side edge of the frame bottom plate 311 away from the other side frame 3 is flush with the left and right corresponding side edges of the back plate 2, so as to ensure the overall appearance and appearance consistency of the head frame 10; at the same time, this arrangement can also realize the assembly positioning of the bottom beam 1 and the side frame 3 through the cooperation of the frame bottom plate 311 and the avoidance notch 112, and improve the assembly efficiency of the bottom beam 1 and the side frame 3.

[0069] In order to facilitate the setting of the side oil retaining flange 13 inside the side frame 3, in this embodiment, the side frame 3 includes a frame body 31 and a side sealing plate 32, the frame body 31 extends in the vertical direction and is connected to the back plate 2, the lower end of the frame body 31 is inserted in the avoidance gap 112 and is located outside the side oil retaining flange 13, and the lower end of the frame body 31 is provided with a frame bottom plate 311; the inner side surface of the frame body 31 is provided with a side opening, the side sealing plate 32 is installed on the inner side of the frame body 31 and closes the side opening, and the side oil retaining flange 13 is located on the side of the side sealing plate 32 away from the other side frame 3. By splitting the side frame 3 into the frame body 31 and the side sealing plate 32, the lower end of the frame body 31 can be inserted in the avoidance gap 112, and the side oil retaining flange 13 can be located on the side of the inner side wall of the side frame 3 away from the other side frame 3, so that the lower end of the side frame 3 is sleeved at the side oil retaining flange 13, simplifying the assembly of the side frame 3 and the bottom beam 1.

[0070] In this embodiment, the frame body 31 is detachably connected to the back plate 2, so that the side frame 3 and the back plate 2 can be processed separately, so as to improve the structural setting flexibility of the side frame 3 and reduce the processing cost of the head frame 10; at the same time, this setting allows the side frame 3 and the back plate 2 to be made of different materials to improve the appearance of the head frame 10 and the smoke machine head. In other embodiments, the side frame 3 can also be integrally formed or welded with the back plate 2.

[0071] In order to further prevent oil stains from entering the wiring hole 3111, the frame bottom plate 311 is provided with a hole oil blocking flange 317 protruding upward, and the hole oil blocking flange 317 is arranged around the wiring hole 3111, so that even if some oil stains drip onto the frame bottom plate 311, the oil stains can be prevented from entering the wiring hole 3111. The height of the side oil blocking flange 13 is preferably higher than the height of the hole oil blocking flange 317.

[0072] Furthermore, the lower edge of the side opening is higher than the upper surface of the frame bottom plate 311, so that the side oil retaining flange 13 is clamped between the frame body 31 and the side sealing plate 32, thereby further stopping the oil in the oil retaining space from flowing toward the wiring hole 3111, and further ensuring that the connecting wires at the wiring hole 3111 can be kept away from the oil circuit of the range hood head.

[0073] like Figures 5 to 8 As shown, the frame body 31 includes a frame outer plate portion 312 and a frame inner plate portion 313 which are arranged oppositely and spaced apart in the left-right direction, and the frame inner plate portion 313 is located on the side of the frame outer plate portion 312 facing the other side frame 3. A front plate portion 314 is connected between the front ends of the frame inner plate portion 313 and the frame outer plate portion 312, and the lower end of the frame outer plate portion 312 is connected to the frame bottom plate 311, and the frame bottom plate 311 is spaced apart from the lower end of the frame inner plate portion 313, so that a side opening is formed between the frame bottom plate 311 and the frame inner plate portion 313.

[0074] The back plate 2 includes a vertically arranged back plate body 21, which is perpendicular to the front-to-back direction and the lower end of which is connected to the rear side of the shell bottom plate 11. The left and right sides of the back plate body 21 are folded forward to form a front folding portion 22, the frame body 31 is connected to the front folding portion 22, and the rear end of the side oil retaining flange 13 is connected to the front folding portion 22. The convenience of connecting the back plate 2 and the frame body 31 can be improved, and it is conducive to the coordination between the back plate 2 and the side oil retaining flange 13. In other embodiments, the back plate 2 may not be provided with the front folding portion 22, and the frame outer plate portion 312 of the side frame 3 forms the left and right sides of the head frame 10. At this time, the side oil retaining flange 13 extends from the front side edge of the shell bottom plate 11 to the rear side edge.

[0075] In order to improve the stability and convenience of the connection between the frame body 31 and the back plate 2, a rear connecting edge 310 is extended backward from the rear side of the frame outer plate 312, and the rear connecting edge 310 is located on the inner side of the front folding edge 22 and is in contact with the front folding edge 22. The rear connecting edge 310 and the front folding edge 22 are fastened by side fasteners, and the side fasteners are preferably arranged at intervals in the vertical direction to improve the connection reliability between the side frame 3 and the back plate 2. The lower end of the rear connecting edge 310 is higher than the side oil retaining flange 13 to avoid interference between the rear connecting edge 310 and the side oil retaining flange 13.

[0076] Furthermore, the rear edge of the frame inner plate 313 is vertically folded to form a rear plate 319, which is fitted with the front side of the back plate body 21, and the rear plate 319 and the back plate body 21 are connected by a rear fastener penetrating the two, and the rear fasteners are preferably arranged in multiple intervals along the vertical direction to ensure the connection fasteners between the inner side of the side frame 3 and the back plate 2, so that both the inner and outer ends of the side frame 3 can be reliably fixed to the back plate 2, thereby improving the overall rigidity of the head frame 10, thereby reducing the probability of vibration of the head frame 10 during the operation of the integrated stove. The rear plate 319 is preferably located between the frame outer plate 312 and the frame inner plate 313, thereby preventing the rear plate 319 and the rear fastener from being exposed in the smoke chamber 8, improving the overall aesthetics of the head frame 10, and reducing the damage of oil smoke to the rear fastener.

[0077] In this embodiment, the width of the lower end of the side frame 3 in the front-to-back direction is greater than the width of the middle and upper ends of the side frame 3 in the front-to-back direction, so that the lower end of the side frame 3 protrudes forward, so that the front side surface of the middle part of the side frame 3 can be used to install the smoke guide plate assembly 30, and the front side surface of the lower end of the side frame 3 can be flush with the front side surface of the front cross beam 12, thereby ensuring the appearance consistency of the entire smoke machine head.

[0078] That is, the frame outer plate portion 312 includes a main outer plate portion and an end outer plate portion, the end outer plate portion is connected to the lower end of the main outer plate portion, and the width of the end outer plate portion in the front-to-back direction is greater than the width of the main outer plate portion in the front-to-back direction, the main outer plate portion and the frame inner plate portion 313 are arranged opposite to each other in the left-right direction, and the front plate portion 314 is connected between the main outer plate portion and the frame inner plate portion 313. The front end of the end outer plate portion is vertically folded to form a front flap portion 315, and the front flap portion 315 is arranged flush with the front cross beam 12.

[0079] The outer edge of the frame bottom plate 311 is connected to the frame outer plate portion 312, and the front side edge of the frame bottom plate 311 is in contact with the front folding portion 22. Specifically, the frame bottom plate 311 is formed by vertically folding the lower end of the frame outer plate portion 312. In order to improve the tightness and reliability of the cooperation between the side frame 3 and the bottom beam 1, in this embodiment, the remaining edges of the frame bottom plate 311 are folded upward to form a bottom plate flange 318, the shape of the bottom plate flange 318 is adapted to the shape of the side oil retaining flange 13, and the outer side surface of the bottom plate flange 318 is fitted with a side of the side oil retaining flange 13 away from the oil retaining space, that is, the side oil retaining flange 13 is partially sandwiched between the side sealing plate 32 and the bottom plate flange 318, thereby enabling the assembly positioning of the frame body 31 and the bottom beam 1 to be achieved through the cooperation of the bottom plate flange 318 and the side oil retaining flange 13, and ensuring the assembly accuracy of the two. The upper end of the bottom plate flange 318 forms the lower side edge of the side opening.

[0080] In this embodiment, the side oil retaining flange 13 and the bottom plate flange 318 are both L-shaped structures, one side of the L-shaped structure extends in the front-to-back direction, and the other side of the L-shaped structure extends in the left-to-right direction, and the L-shaped structure adopts a circular arc smooth transition connection at the corner, thereby facilitating the front end of the side oil retaining flange 13 to be vertically abutted against the front cross beam 12, and the rear end of the side oil retaining flange 13 to be vertically abutted against the front folding portion 22, simplifying the structure of the side oil retaining flange 13. That is, the side oil retaining flange 13 includes a longitudinal flange portion extending in the front-to-back direction and a transverse flange portion extending in the left-to-right direction. The height of the bottom plate flange 318 is preferably equal to the height of the side oil retaining flange 13 to improve the appearance.

[0081] like Figure 6 , Figure 7 and Fig. 9 As shown, the side sealing plate 32 includes a main sealing plate portion 321, which closes the side opening and is arranged flush with the frame inner plate portion 313, thereby making the side of the side frame 3 facing the smoke collecting chamber 8 smooth, reducing the probability of oil and dirt entering the interior of the side frame 3 through the connection between the side sealing plate 32 and the frame body 31, and improving the cleaning convenience of the head frame 10.

[0082] The lower end of the main sealing plate portion 321 is partially recessed in the direction toward the oil retaining space to form a convex portion 323. The main sealing plate portion 321 is flush with the inner side surface of the side frame 3 and closes the side opening. The side oil retaining flange 13 is sandwiched between the frame body 31 and the convex portion 323. Specifically, the side oil retaining flange 13 is partially sandwiched between the bottom plate flange 318 and the convex portion 323. The convex portion 323 can ensure that the main sealing plate portion 321 is flush with the bottom plate flange 318 and the frame inner plate portion 313, while ensuring that the longitudinal flange portion of the side oil retaining flange 13 can be sandwiched between the convex portion 323 and the bottom plate flange 318, thereby improving the assembly convenience of the side frame 3 and the side oil retaining flange 13; at the same time, the convex portion 323 wraps the longitudinal flange portion and part of the bottom plate flange 318, thereby improving the tightness of the side frame 3 and the side oil retaining flange 13, reducing the gap at the assembly of the three, thereby further reducing the probability of oil dirt entering the frame bottom plate 311 through the assembly gap. The lower end of the main sealing plate portion 321 is preferably in contact with the shell bottom plate 11.

[0083] In order to improve the assembly reliability of the side sealing plate 32 and the frame body 31, the upper end of the side sealing plate 32 is inserted into the interior of the frame body 31, thereby effectively preventing the oil stains attached to the side surface of the frame inner plate 313 facing the smoke collecting chamber 8 from entering the interior of the frame body 31 through the connection between the side sealing plate 32 and the frame inner plate 313, and better ensuring the assembly tightness and reliability of the side sealing plate 32 and the frame body 31.

[0084] Specifically, the upper end of the main sealing plate portion 321 is bent to form an upper inserting edge portion 324, which is parallel to and spaced from the main sealing plate portion 321, and is inserted into the inner side of the frame body 31, and the upper inserting edge portion 324 is in contact with the inner side surface of the frame body 31 to ensure the reliability of the cooperation between the side sealing plate 32 and the frame body 31. The lower end of the frame inner plate portion 313 abuts against the bending of the upper inserting edge portion 324 and the main sealing plate portion 321 to reduce the gap at the connection between the two.

[0085] Furthermore, the rear edge of the main sealing plate portion 321 is folded vertically outward to form a rear flange portion 326, which is in contact with the front side of the back plate body 21 to prevent the rear edge of the side sealing plate 32 from scratching the back plate 2 and reduce the gap between the side sealing plate 32 and the back plate 2. The upper end of the rear flange portion 326 is also provided with an upper insert portion 324, which is in contact with the front side of the rear plate portion 319 of the frame body 31.

[0086] like Figure 7 , Fig. 9 and Fig.10 As shown, in order to improve the installation reliability of the side sealing plate 32, the left and right ends of the front cross beam 12 are folded backward to form a rear folding portion 14, and the front side of the side sealing plate 32 is clamped between the rear folding portion 14 and the frame body 31. The frame body 31, the side sealing plate 32 and the rear folding portion 14 are connected by fixing screws that penetrate the three in sequence. This arrangement allows the frame body 31, the bottom beam 1 and the side sealing plate 32 to be fastened together, ensuring the tightness of the assembly of the three and reducing the number of fastening structures. The lower end of the rear folding portion 14 abuts against the upper side of the side oil retaining flange 13 to reduce the gap between the two while avoiding interference between the rear folding portion 14 and the side oil retaining flange 13.

[0087] Furthermore, the front side of the main sealing plate portion 321 is bent to form a front connecting edge portion 325, which is parallel to and spaced from the main sealing plate portion 321; the inner end of the front flap portion 315 is folded backward to form a fixing edge portion 316, which is sandwiched between the front connecting edge portion 325 and the rear folding edge portion 14, and the fixing screw member passes through the rear folding edge portion 14, the fixing edge portion 316 and the front connecting edge portion 325 in sequence. The fixing edge portion 316 is flush with the main sealing plate portion 321, and the rear edge of the fixing edge portion 316 forms the front edge of the side opening.

[0088] In order to further improve the installation stability of the side sealing plate 32, the rear side of the lower end of the main sealing plate portion 321 is folded to form a bottom flange portion 322, and the bottom flange portion 322 is located on the rear side of the side oil retaining flange 13 and on the side of the main sealing plate portion 321 away from the smoke collecting chamber 8. The bottom flange portion 322 is fastened to the shell bottom plate 11 by a bottom fastener. This arrangement allows the front and rear sides of the side sealing plate 32 to be reliably fixed, reduces the probability of the side sealing plate 32 shaking, and improves the overall structural rigidity of the side frame 3. In other embodiments, the rear flange portion 326 may also be fastened to the back panel body 21 by fasteners.

[0089] like Fig.11 and Fig.12 As shown, in the present embodiment, the head frame 10 also includes a decorative strip 5, which is installed between the top of the front cross beam 12 and the lower end of the smoke guide plate assembly 30.
