[0036] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0037] This utility model discloses a smoke hood. Please refer to [link / reference]. Figures 1 to 4,include:

[0038] The main body 1 of the range hood has an electric control cavity. The front plate of the main body 1 of the range hood has a first mounting port 11 that communicates with the electric control cavity. The side plate of the main body 1 of the range hood has a second mounting port 12 that communicates with the electric control cavity. The top plate of the main body 1 of the range hood has an air curtain inlet 13. The bottom plate of the main body 1 of the range hood has an air curtain exhaust port 14. The bottom plate of the electric control cavity has an air curtain bracket 15 that corresponds to the air curtain exhaust port 14.

[0039] The air curtain assembly 2 is installed in the electrical control cavity through the first mounting port 11 and is detachably connected to the air curtain bracket 15. One end of the air curtain assembly 2 near the side plate of the main body 1 of the smoke hood is aligned with the second mounting port 12. The air curtain assembly 2 draws in air through the air curtain inlet 13 and exhausts air through the air curtain outlet 14 to form an air curtain.

[0040] Control panel 3 is connected to the front panel of the range hood body 1 and covers the first mounting port 11;

[0041] Panel control component 4 is located on control panel 3 and housed in electrical control cavity through first mounting port 11.

[0042] In this embodiment, the panel control component 4 is located on the rear side of the control panel 3 (the side facing the electrical control cavity).

[0043] When the air curtain assembly 2 needs to be installed, the operator holds the air curtain assembly 2 with one hand and inserts it into the electrical control cavity through the first mounting port 11, so that the air curtain assembly 2 is detachably connected to the air curtain bracket 15. During this process, the operator can reach into the electrical control cavity through the second mounting port 12 with the other hand to hold or grasp the end of the air curtain assembly 2, so that the air curtain assembly 2 and the air curtain bracket 15 can be stably and reliably detachably connected. After the installation of the air curtain assembly 2 is completed, the operator can hold the control panel 3 and install it on the front panel of the smoke machine body 1, so that the panel control assembly 4 is housed in the electrical control cavity through the first mounting port 11, and the control panel 3 covers the first mounting port 11.

[0044] When it is necessary to disassemble the air curtain assembly 2, first remove the control panel 3 installed on the front panel of the main body 1 of the smoke machine, and then let the panel control assembly 4 come out of the electrical control cavity and the first mounting port 11 in turn, so that the first mounting port 11 is exposed; then, the operator can put one hand into the first mounting port 11 and apply force to the air curtain assembly 2, so that the air curtain assembly 2 is separated from the air curtain bracket 15, until the air curtain assembly 2 is removed from the first mounting port 11. During this process, the operator can put the other hand into the electrical control cavity from the second mounting port 12 to hold or grab the end of the air curtain assembly 2, so that the air curtain assembly 2 can be quickly separated from the air curtain bracket 15.

[0045] In this invention, the air curtain assembly 2 can be inserted into or removed from the electrical control cavity through the first mounting port 11, making operation more convenient. The second mounting port 12 allows another hand to reach into the electrical control cavity to hold or grasp the end of the air curtain assembly 2, making the disassembly and assembly process more convenient.

[0046] With the above-described disassembly and assembly method, the operator only needs to stand directly in front of the main body 1 of the smoke machine and maintain a standing posture to complete the disassembly and assembly of the air curtain component 2 and the control panel 3, so that the air curtain component 2 can enter and exit the first horizontal installation port 11 directly facing the operator. Compared with the prior art, which requires the top plate to be removed from the smoke machine, the disassembly and assembly method of the air curtain component 2 of this utility model is more convenient and less labor-intensive, and it is also easier for the operator to directly observe the disassembly and assembly of the air curtain component 2.

[0047] When the range hood is in use, the air curtain assembly 2 is activated, continuously drawing external air into the electronic control chamber from the air curtain inlet 13. At the same time, the air is discharged downward from the air curtain exhaust outlet 14 to form an air curtain.

[0048] exist Figure 2 In the embodiment shown, when two air curtain components 2 are provided and are spaced apart on the left and right sides of the main body 1 of the smoke machine, the second mounting port 12 is simultaneously opened on the left and right side plates of the main body 1 of the smoke machine, so as to facilitate the workers to perform auxiliary work on the disassembly and assembly of the corresponding air curtain components 2 by inserting into the second mounting port 12.

[0049] In this embodiment, if the range hood is observed from the user's perspective, the front panel of the range hood body 1 specifically refers to the panel structure facing the user, the side panels of the range hood body 1 refer to the panel structures on both sides, the top panel of the range hood body 1 refers to the upper panel structure, and the bottom panel of the range hood body 1 refers to the lower panel structure.

[0050] Please see Figures 2 to 11 The smoke hood of this utility model includes an air curtain assembly 2 comprising a cyclone lower cover 21 and a cross-flow fan 22. The cross-flow fan 22 is installed on the cyclone lower cover 21, and both the cyclone lower cover 21 and the cross-flow fan 22 are detachably connected to the air curtain bracket 15.

[0051] When installing the air curtain assembly 2, first install the cross-flow fan 22 onto the cyclone lower cover 21. Then, the operator holds the air curtain assembly 2 with one hand and simultaneously inserts the cross-flow fan 22 and the cyclone lower cover 21 into the electrical control cavity through the first installation port 11. This allows the lower cyclone lower cover 21 to be detachably connected to the air curtain bracket 15, achieving the initial installation of the air curtain assembly 2. Next, the cross-flow fan 22 is connected to the air curtain bracket 15 for further installation. The air curtain bracket 15 forms multiple points of support with the detachable connection points of the cyclone lower cover 21 and the cross-flow fan 22 to maintain the stable installation of the air curtain assembly 2. During installation, the operator can use their other hand to reach into the electrical control cavity through the second installation port 12 to hold or grasp the ends of the cyclone lower cover 21 and / or the cross-flow fan 22, ensuring a stable and reliable detachable connection between the cyclone lower cover 21 and the cross-flow fan 22 and the air curtain bracket 15.

[0052] When it is necessary to disassemble the air curtain assembly 2, first remove the control panel 3 installed on the front panel of the main body 1 of the smoke machine, and then let the panel control component 4 detach from the electrical control cavity and the first mounting port 11 in turn, so that the first mounting port 11 is exposed. Then, the operator can put one hand into the first mounting port 11 and apply force to the cyclone lower cover 21 and / or the cross-flow fan 22 of the air curtain assembly 2, first to make the cross-flow fan 22 separate from the air curtain bracket 15, then to make the cyclone lower cover 21 separate from the air curtain bracket 15, and then apply force to the air curtain assembly 2 until the air curtain assembly 2 is removed from the first mounting port 11. During this process, the operator can put the other hand into the electrical control cavity from the second mounting port 12 to hold or grasp the end of the cyclone lower cover 21 and / or the cross-flow fan 22 of the air curtain assembly 2, so that the air curtain assembly 2 can be quickly separated from the air curtain bracket 15.

[0053] The smoke hood of this utility model has a buckle 151 on the rear side of the air curtain bracket 15, a connecting piece 152 on the front side of the air curtain bracket 15, and a connecting hole on the connecting piece 152. The lower cover 21 of the cyclone has a slot 211 on the rear side. The cross-flow fan 22 has a connecting part corresponding to the connecting piece 152, and a connecting hole on the connecting part. After the air curtain assembly 2 is installed on the air curtain bracket 15, the buckle 151 is engaged in the slot 211, and the connecting hole on the connecting piece 152 is connected to the connecting hole on the connecting part of the cross-flow fan 22.

[0054] like Figure 2 , Figure 6 and Figure 10As shown, taking the installation of the left-side air curtain assembly 2 as an example, when installing the air curtain assembly 2, the operator holds the air curtain assembly 2 with one hand and simultaneously inserts the cross-flow fan 22 and the cyclone lower cover 21 into the electrical control cavity through the first installation port 11, causing the air curtain assembly 2 to move to the left. At the same time, the other hand enters through the second installation port 12 and holds the left end of the air curtain assembly. After the air curtain assembly 2 is moved into place, the air curtain assembly 2 is first turned counterclockwise, causing the cyclone lower cover 21 of the air curtain assembly 2 to tilt downwards, so that the slot 211 tilts downwards to smoothly engage with the buckle 151. The groove wall of the slot 211 is inserted into the buckle. After engaging, the air curtain assembly 2 is straightened to achieve the initial installation of the air curtain assembly 2. Then, the connecting hole on the connecting piece 152 is aligned with the connecting hole on the connecting part of the cross-flow fan 22 and connected through the connector, so that the cross-flow fan 22 and the air curtain bracket 15 can be detachably connected to achieve the further installation of the air curtain assembly 2. The air curtain bracket 15 is used to form multiple points of support with the detachable connection points of the cyclone lower cover 21 and the cross-flow fan 22 to maintain the stable installation of the air curtain assembly 2.

[0055] In practical applications, at least two clips 151 are spaced apart on the rear side of the air curtain bracket 15 (only two are shown in the figure), which ensures a secure connection between the air curtain bracket 15 and the cyclone lower cover 21. Connecting pieces 152 are located on both sides of the front of the air curtain bracket 15, which can fix the cross-flow fan 22 without affecting the installation of the air curtain assembly onto the air curtain bracket 15. Furthermore, with the clips 151 on the rear and the connecting pieces 152 on the front, the clips are used for connection in a location not visible to the user, while the connecting piece 152 and the cross-flow fan 22 are connected by a connector on the user-facing side, facilitating the assembly and disassembly of the air curtain assembly 2.

[0056] In this embodiment, each buckle 151 has a notch facing the front of the air curtain bracket 15, allowing the slot wall of the slot 211 to be horizontally inserted. The connecting piece 152 is located near the second mounting port 12, and its connecting hole has a horizontally through-hole structure facing the rear of the air curtain bracket 15.

[0057] Based on the above embodiment, the opening of the buckle 151 is inclined in opposite directions to form two guide surfaces, so that when the air curtain assembly 2 in the inclined state enters and achieves engagement with the buckle 151, the guide surfaces can guide the cyclone lower cover 21, so that the buckle 151 can quickly engage with the slot 211.

[0058] The smoke hood of this utility model includes a cross-flow fan 22 comprising a volute 221, a support 222, an impeller assembly 223, and a fan 224. The support 222 is located on both sides of the volute 221, and the two ends of the volute 221 are respectively connected to the corresponding support 222. The impeller assembly 223 is rotatably connected inside the volute 221. The fan 224 is located on one side of the support 222, and its output end is connected to the impeller assembly 223.

[0059] There are two supports 222, which are respectively located on both sides of the volute 221, so that the two supports 222 are connected to the two ends of the volute 221, so that the volute 221 and the two supports 222 together form an upward "U" shape structure, so that the impeller assembly 223 is rotatably connected to the "U" shape structure.

[0060] When using the range hood, the control fan 224 is started, driving the impeller assembly 223 to rotate. The rotating impeller assembly 223 continuously draws external gas into the electronic control chamber from the air curtain inlet 13. At the same time, the gas is discharged downward from the air curtain exhaust outlet 14 to form an air curtain.

[0061] During installation, the cyclone lower cover 21 supports the volute 221, and both supports 222 are connected to the corresponding connecting pieces 152 to achieve stable installation of the air curtain assembly 2.

[0062] According to one embodiment of this utility model, please refer to Figure 6 and Figure 7 The support 222 has extensions 2221 on both sides extending away from the volute 221. The extensions 2221 form a connecting part and have connecting holes. The extensions 2221 are connected to the connecting piece 152.

[0063] Among them, each extension 2221 located on the opposite side of the two supports 222 extends in opposite directions to form a plate-like structure, so that after the air curtain assembly 2 is installed by tilting it forward and backward, each extension 2221 and the corresponding extension 2221 are on the same straight line.

[0064] During installation, the air curtain assembly 2 is tilted forward and backward downward, causing the slot 211 to tilt downward so that it can smoothly engage with the buckle 151. The groove wall of the slot 211 is inserted into the buckle. At the same time, the extension 2221 abuts against the rear side of the connecting piece 152 and moves downward until the connecting hole of the extension 2221 communicates with the connecting hole of the connecting piece 152. At this time, the operator can reach into the electrical control cavity with his other hand from the second mounting port 12 and insert the connecting shaft into the connecting hole of the extension 2221 and the connecting hole of the connecting piece 152 at the same time to keep them connected.

[0065] According to another embodiment of this utility model, please refer to Figure 8 and Figure 9 The air curtain assembly 2 also includes a limiting baffle 23, which is connected to the volute of the cross-flow fan 22. The limiting baffle 23 has limiting parts 231 on both sides, which are parallel to the connecting piece 152 and form a connecting part. When the air curtain assembly 2 is installed on the air curtain bracket 15, the limiting parts 231 on both sides are inserted into the front side of the connecting piece 152. The limiting parts 231 are also provided with connecting grooves corresponding to the limiting holes on the connecting piece 152.

[0066] When installing the air curtain assembly 2, the operator holds the air curtain assembly 2 with one hand and simultaneously inserts the cross-flow fan 22 and the cyclone lower cover 21 into the electrical control cavity through the first installation port 11, causing the air curtain assembly 2 to tilt forward and backward downward, so that the slot 211 tilts downward to smoothly engage with the buckle 151. The groove wall of the slot 211 inserts into the buckle. After it is engaged, the air curtain assembly 2 is straightened, so that the lower cyclone cover 21 is detachably connected to the buckle 151 of the air curtain bracket 15, thus achieving the initial installation of the air curtain assembly 2. Afterward, the straightened air curtain assembly 2 is secured by the buckle 151. Rotating in the opposite direction around the center, the limiting part 231 of the limiting baffle 23 moves downward and moves to the front side of the corresponding connecting piece 152 until the connecting groove on the limiting part 231 and the limiting hole on the connecting piece 152 are connected. Then, the connecting shaft is inserted into the connected connecting groove and the limiting hole through the second mounting port 12, so that the cross-flow fan 22 and the air curtain bracket 15 can be detachably connected to achieve further installation of the air curtain assembly 2. The air curtain bracket 15 forms multi-point support with the detachable connection points of the cyclone lower cover 21 and the cross-flow fan 22 to maintain the stable installation of the air curtain assembly 2.

[0067] In this embodiment, the connecting groove opens upward so that after the connector is inserted, it is locked in the connecting groove by the connector, and the limiting part 231 is limited by the connecting shaft, so as to keep the air curtain assembly 2 installed stably and prevent the air curtain assembly 2 from jumping upward.

[0068] According to the third embodiment of this utility model, please refer to... Figure 8 and Figure 9 The support 222 has extensions 2221 on both sides extending away from the volute 221. The extensions 2221 form connecting parts, which are first connecting parts and abut against the rear side of the connecting piece 152. The air curtain assembly 2 also includes a limiting baffle 23, which is connected to the volute of the cross-flow fan 22. The limiting baffle 23 has limiting parts 231 on both sides, which are parallel to the connecting piece 152 and form connecting parts, which are second connecting parts. When the air curtain assembly 2 is installed on the air curtain bracket 15, the limiting parts 231 on both sides are inserted into the front side of the connecting piece 152. The limiting parts 231 also have connecting grooves corresponding to the limiting holes on the connecting piece 152.

[0069] When installing the air curtain assembly 2, the upright air curtain assembly 2 rotates in the opposite direction around the buckle 151. The limiting part 231 of the limiting baffle 23 moves downward and moves to the front side of the corresponding connecting piece 152, until the connecting groove on the limiting part 231 communicates with the limiting hole on the connecting piece 152. At the same time, the extension part 2221 abuts against the rear side of the connecting piece 152 and moves downward, so that the extension part 2221 and the limiting part 231 abut against the rear and front sides of the connecting piece 152 respectively, forming a front and rear limiting of the connecting piece 152, keeping the installation of the air curtain assembly 2 stable. Then, the connecting shaft is inserted into the connected connecting groove and the limiting hole through the second mounting port 12, so that the cross-flow fan 22 and the air curtain bracket 15 can be detachably connected to achieve further installation of the air curtain assembly 2.

[0070] Based on the above embodiment, a connecting hole is provided on the extension 2221. The connecting hole of the extension 2221, the connecting groove of the limiting part 231, and the limiting hole on the connecting piece 152 are connected to each other so that the connecting shaft passes through the connecting hole, the connecting groove, and the limiting hole at the same time to complete the stable installation of the air curtain assembly 2.

[0071] Please refer to Figure 2 and Figure 3 The range hood of this utility model also includes a maintenance cover plate 5, which is connected to the side of the main body 1 of the range hood and blocks the second mounting port 12.

[0072] When disassembling and replacing the air curtain assembly 2, first remove the maintenance cover 5 to open the second installation port 12, so that the operators can carry out related work through the second installation port 12.

[0073] After the disassembly and replacement of the air curtain assembly 2 are completed, the maintenance cover plate 5 is installed to seal the second installation port 12, preventing the air in the electrical control cavity from being directly discharged from the second installation port 12 during the use of the range hood, and also preventing external debris from entering the electrical control cavity from the second installation port 12.

[0074] Please refer to Figure 4 and Figure 5 The smoke hood of this utility model has a mounting position 16 recessed into the electrical control cavity on the side plate of the main body 1 of the smoke hood, and a second mounting port 12 is located in the mounting position 16. The maintenance cover plate 5 is adapted to the shape of the mounting position 16.

[0075] The mounting position 16 forms an installation space that is compatible with the maintenance cover plate 5. After the maintenance cover plate 5 is installed and the second mounting port 12 is closed, a relatively sealed installation structure is formed between the maintenance cover plate 5 and the mounting position 16. This prevents the air in the electrical control cavity from being directly discharged from the second mounting port 12, and also prevents external debris from entering the electrical control cavity from the second mounting port 12. Furthermore, the shape of the maintenance cover plate 5 is compatible with the mounting position 16, so that the outer side of the installed maintenance cover plate 5 is flush with the outer wall of the range hood body 1, thereby ensuring the aesthetics of the range hood body 1.

[0076] Please refer to Figures 2 to 5 The smoke hood of this utility model has a mounting hole 161 on the mounting position 16 and a connection hole 51 corresponding to the mounting hole 161 on the maintenance cover plate 5.

[0077] In this embodiment, the mounting hole 161 is an internally threaded hole, so that after the maintenance cover 5 is placed on the mounting position 16, a screw is inserted into the connecting hole 51 and the screw is threaded into the mounting hole 161 to achieve stable installation of the maintenance cover 5.

[0078] Based on the above embodiment, the connecting hole 51 is a countersunk hole to accommodate the head of the screw, so that the head of the screw screw is screwed in into the connecting hole 51, and the outer side of the maintenance cover 5 after installation is flush with the outer wall of the range hood body 1, maintaining the aesthetics of the range hood body 1.

[0079] Please refer to Figure 1 and Figure 2 The range hood of this utility model also includes a side baffle assembly 6, which is connected to both sides of the range hood body 1 and covers the side plate of the range hood body 1.

[0080] In this embodiment, two side baffle assemblies 6 are provided, and the two side baffle assemblies 6 are respectively disposed on both sides of the range hood body 1. Specifically, the side baffle assemblies 6 can be installed by means of screws, snap-fit, or hook-on. Moreover, the two adjacent ends of the side baffle assemblies 6 abut against the outer side of the range hood body 1, and the upper end of the side baffle assemblies 6 covers the side of the range hood body 1 where the mounting position 16 is opened, and at the same time covers the outer side of the maintenance cover 5 to form a secondary seal, reducing the possibility of external oil fumes entering the electrical control cavity from the second mounting port 12.

[0081] During use, the two side baffle assemblies 6 located on both sides of the main body 1 of the range hood form a blocking effect on the oil fumes at the bottom of the main body 1 of the range hood, preventing the oil fumes from spreading outward from both sides, so that the oil fumes are fully discharged and the user experience is improved.

[0082] When replacing or repairing the air curtain assembly 2, first remove the two side baffle assemblies 6, then remove the maintenance cover 5 and disassemble the air curtain assembly 2.

[0083] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
