Description

Technical Field

[0001] This utility model relates to the field of smoke hood technology, specifically to a smoke hood. Background Technology

[0002] A range hood, also known as a cooking hood, is a kitchen appliance that purifies the kitchen environment. Installed above the stove, it quickly removes harmful cooking fumes and vents them outdoors. An air curtain assembly is installed on the top panel of the range hood. This assembly directs airflow downwards through vents on the top panel, creating an air curtain below the panel to reduce fume escape. When the range hood is running, some fumes rush towards the top panel and flow forward due to the adhesion effect. In existing technology, the air curtain vents are directly on the flat surface of the top panel, causing the fumes to flow until they reach the vents before being blocked by the air curtain. This results in some fumes flowing upwards from the vents and adhering to the air curtain assembly, which, over time, affects its effectiveness. Range hoods typically include a ceiling light for auxiliary lighting during cooking. However, in existing technology, these lights protrude from the top panel surface, affecting the overall aesthetics of the range hood. Utility Model Content

[0033] 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:

[0034] This utility model discloses a smoke hood. Please refer to [link / reference]. Figure 1 , Figures 7 to 11 The smoke hood of this utility model includes a housing 1, a lamp panel assembly 2, and an air curtain assembly 3. The housing 1 has a top plate 11 and an electrical control cavity 12 located above the top plate 11. The top plate 11 is provided with a first recess 111 and a second recess 112, which are arranged front to back. The first recess 111 is located in front of the second recess 112. An air curtain exhaust port 1111 is provided in the first recess 111. The housing 1 is also provided with an air intake channel that allows external air to communicate with the electrical control cavity 12. The lamp panel assembly 2 is installed in the second recess 112 and is adapted to the second recess 112. The air curtain assembly 3 is located in the electrical control cavity 12, and the exhaust side of the air curtain assembly 3 is aligned with the air curtain exhaust port 1111.

[0035] In this embodiment, the air curtain exhaust port 1111 connects the electronic control cavity 12 and the first concave cavity 111. The air curtain assembly 3 is installed on the upper surface of the top plate 11 and located at the air curtain exhaust port 1111. When the air curtain assembly 3 is running, outside air enters the electronic control cavity 12 along the air intake channel. The air curtain assembly 3 draws in the air that enters the electronic control cavity 12 from the air intake channel and exhausts it through the air curtain exhaust port 1111 to form an air curtain below the air curtain exhaust port 1111.

[0036] When the range hood is running, the cooking fumes will flow towards the air intake under the negative pressure formed at the air intake. Some of the fumes will rush towards the top plate 11 and flow forward under the effect of the wall adhesion. When the fumes flow to the first concave cavity 111, the flow path will be interrupted by the edge of the first concave cavity 111, and they will not be able to continue to flow to the bottom of the first concave cavity 111. This can prevent the fumes from flowing into the air curtain exhaust port 111 and avoid the formation of grease on the innermost edge of the air curtain exhaust port 111.

[0037] The lamp panel assembly 2 is installed in the second recess 112 so that it can emit downward illumination. The lamp panel assembly 2 is generally rectangular, and the shape of the second recess 112 corresponds to the shape of the lamp panel assembly 2. Installing the lamp panel assembly 2 in the second recess 112 allows the lower surface of the lamp panel assembly 2 to remain flush with the lower surface of the top plate 11 where the first and second recesses 111 and 112 are not formed. This improves the overall appearance of the range hood and reduces the accumulation of grease and smoke in the gap between the lamp panel assembly 2 and the top plate 11.

[0038] The smoke hood of this utility model, such as Figure 1 and Figure 7As shown, the first recess 111 is provided with two air curtain exhaust vents 1111, which are respectively located on both sides of the first recess 111 and are symmetrically arranged. The first recess 111 extends along the width direction (left-right direction) of the top plate 11, and the two air curtain exhaust vents 1111 are both opened in the first recess 111 and are spaced apart along the length direction of the first recess 111. There are two sets of air curtain assemblies 3, and the two sets of air curtain assemblies 3 are respectively installed in the electrical control cavity 12 corresponding to the two air curtain exhaust vents 1111. In this way, the number of air curtains below the top plate 11 can be increased, thereby improving the blocking effect of oil fumes.

[0039] The smoke hood of this utility model, such as Figures 2 to 6 As shown, the smoke hood also includes an air collection box assembly 4, which contains an exhaust fan. The housing 1 has a cover plate 13 with an installation port. The air collection box assembly 4 is installed inside the housing 1 and extends out of the housing 1 from the installation port. The portion of the housing 1 between the cover plate 13 and the top plate 11 forms an electrical control cavity 12. There is a first gap a between the air collection box assembly 4 and the installation port. The first gap a communicates with the electrical control cavity 12. External air enters the electrical control cavity 12 through the first gap a, forming an air intake channel.

[0040] The electrical control cavity 12 is located in front of the mounting port, that is, in front of the air collecting box assembly 4 and the first gap a. The first gap a is formed between the front edge of the air collecting box assembly 4 and the mounting port. When the air curtain assembly 3 is working, the outside air enters the electrical control cavity 12 through the first gap a, and is then discharged by the air curtain assembly 3 through the air curtain exhaust port 111. In this way, it is not necessary to open an air inlet on the top plate 11 to communicate with the electrical control cavity 12, thereby simplifying the structure of the cover plate 13 and preventing external dust and other debris from easily falling into the electrical control cavity 12.

[0041] The smoke hood of this utility model, such as Figure 5 As shown, it also includes a surrounding plate 5, and a cover plate 13 is provided with a support groove 131 around the mounting opening. The surrounding plate 5 is installed in the support groove 131. The surrounding plate 5 is arranged around the air collecting box assembly 4. There is a second gap b between the surrounding plate 5 and the outer wall surface of the air collecting box assembly 4. External air enters the first gap a through the second gap b.

[0042] The enclosure 5 conceals and protects the air collecting box assembly 4 and the second gap b, preventing the first gap a from being directly exposed to the user's view, thus serving a decorative purpose for the range hood. The second gap b extends along the height of the air collecting box assembly 4. The top part of the second gap b communicates with the outside air, and the bottom part of the second gap b communicates with the first gap a. When the air curtain assembly 3 is working, outside air enters the second gap b from the top of the air collecting box assembly 4 and the enclosure 5, then enters the first gap a through the second gap b, and then enters the electrical control cavity 12 through the first gap a, and is then discharged by the air curtain assembly 3 through the air curtain exhaust port 111.

[0043] The smoke hood of this utility model, such as Figures 7 to 10 As shown, the side of the lamp panel assembly 2 closest to the first recess 111 is connected to the top plate 11 by screws, and the side away from the first recess 111 is snapped into the top plate 11; the two sets of air curtain assemblies 3 are connected to the top plate 11 by screws at one end and snapped into the top plate 11 at the other end.

[0044] When installing the lamp panel assembly 2 onto the top plate 11, the rear side of the lamp panel assembly 2 can be snapped into the top plate 11 first, so that the rear side of the lamp panel assembly 2 can be pre-fixed in the second recess 112. After the rear side of the lamp panel assembly 2 is snapped into the top plate 11, the front side of the lamp panel assembly 2 is then fixedly connected to the top plate 11 with screws to achieve the fixed installation of the lamp panel assembly 2 in the second recess 112. This simplifies the installation method of the lamp panel assembly 2 in the second recess 112, thereby improving the installation convenience of the lamp panel assembly 2.

[0045] When installing the air curtain assembly 3, one end of the air curtain assembly 3 can be snapped into the top plate 11 first, so that one end of the air curtain assembly 3 can be pre-fixed on the top plate 11. After one end of the air curtain assembly 3 is snapped into the top plate 11, the other end of the air curtain assembly 3 is fixedly connected to the top plate 11 by screws, so as to realize the fixed installation of the air curtain assembly 3 on the top plate 11. In this way, the installation method of the air curtain assembly 3 on the top plate 11 can be simplified, thereby improving the installation convenience of the air curtain assembly 3.

[0046] The two sets of air curtain components 3 can be defined as the left air curtain component and the right air curtain component, respectively. When installing the left air curtain component, first snap the left end of the left air curtain component into place with the top plate 11. After snapping it into place, then fix the right end of the left air curtain component to the top plate 11 with screws. When installing the right air curtain component, first snap the right end of the right air curtain component into place with the top plate 11. After snapping it into place, then fix the left end of the right air curtain component to the top plate 11 with screws.

[0047] The smoke hood of this utility model, such as Figure 4 and Figure 6 As shown, the cover plate 13 is provided with an inspection port 132 and an inspection cover 14 covering the inspection port 132. The downward projection of the inspection port 132 covers the position where the top plate 11 and the lamp panel assembly 2 are connected to the top plate 11 by screws and the opposite end of the two sets of air curtain assemblies 3.

[0048] The inspection cover 14 detachably covers the inspection port 132. When the front side of the lamp panel assembly 2 is fixedly connected to the top plate 11, the screws are passed through the top plate 11 and the lamp panel assembly 2 in sequence from inside the electrical control cavity 12, and also from above the top plate 11. The connection position between the lamp panel assembly 2 and the top plate 11 is aligned with the inspection port 132, so the head of the screw is also aligned with the inspection port 132. When it is necessary to remove the screws, the inspection cover 14 can be opened first to expose the inspection port 132 so that the screws can be exposed through the inspection port 132. Then, the operator can remove the screws through the inspection port 132 to disconnect the connection between the front side of the lamp panel assembly 2 and the top plate 11.

[0049] The ends of the two air curtain components 3 that are close to each other are aligned with the inspection port 132. That is, the right end of the left air curtain component and the left end of the right air curtain component are aligned with the inspection port 132. Therefore, the screws that fix the two air curtain components 3 to the top plate 11 are also aligned with the inspection port 132. When it is necessary to disassemble the air curtain components 3, the inspection cover 14 can be opened first to expose the inspection port 132 so that the screws can be exposed through the inspection port 132. Then, the operator can remove the screws through the inspection port 132 to disconnect the connection between the two air curtain components 3 and the top plate 11. Then, the two air curtain components 3 can be pulled out one by one from the inspection port 132 in an upward inclined direction. While pulling out the two air curtain components 3, the snap-fit ​​relationship between the two air curtain components 3 and the top plate 11 can be directly released, thereby improving the convenience of disassembly and maintenance of the two air curtain components 3.

[0050] The smoke hood of this utility model, such as Figures 10 to 12 As shown, a first connector 113 is provided on the rear side of the second cavity 112, a first connecting hole 1121 is provided on the front side of the second cavity 112, a second connector 21 is provided on the rear side of the top of the lamp panel assembly 2, a third connector 22 is provided on the front side of the top of the lamp panel assembly 2, a second connecting hole 221 is provided on the third connector 22, the first connecting hole 1121 and the second connecting hole 221 are connected by screws, and the second connector 21 is engaged with the first connector 113.

[0051] The second connector 21 and the third connector 22 are located on the top of the lamp panel assembly 2. The second connector 21 is located on the front side of the lamp panel assembly 2, and the third connector 22 is located on the rear side of the lamp panel assembly 2. The position of the first connector 113 in the second cavity 112 corresponds to the position of the second connector 21, and the position of the first connecting hole 1121 corresponds to the position of the third connector 22. The first connector 113 and the second connector 21 can be directly connected without the aid of other parts, while the second connecting hole 221 of the third connector 22 and the first connecting hole 1121 need to be connected by screws.

[0052] The smoke hood of this utility model, such as Figures 7 to 10As shown, the second cavity 112 is also provided with a third connecting hole 1122, and the front side of the top of the lamp panel assembly 2 is also provided with a plum blossom buckle 23, which is connected to the third connecting hole 1122.

[0053] The plum blossom buckle 23 is snapped into the third connecting hole 1122 for fixation. When installing the light panel assembly 2, after the rear side of the light panel assembly 2 is in place, the plum blossom buckle 23 can be snapped into the third connecting hole 1122 to achieve pre-fixation of the light panel assembly 2 to the top plate 11. This facilitates the user to connect the first connecting hole 1121 and the second connecting hole 221 with screws, further improving the installation convenience of the light panel assembly 2. When the light panel assembly 2 needs to be disassembled for maintenance, after removing the screws connecting the first connecting hole 1121 and the second connecting hole 221, the plum blossom buckle 23 is connected to the third connecting hole 1122, so that the front side of the light panel assembly 2 remains connected to the top plate 11 and will not fall directly. Then, the operator applies force to pull the plum blossom buckle 23 out of the third connecting hole 1122. Thus, the operator does not need to support the light panel assembly 2 when removing screws, improving the disassembly convenience of the light panel assembly 2.

[0054] The smoke hood of this utility model, such as Figure 8 As shown, the top plate 11 is provided with an air curtain bracket 114 corresponding to the air curtain exhaust port 1111. One end of the two air curtain brackets 114 is provided with a support part 1141, and the other end is provided with a snap-fit ​​plate 1142 on both sides. One end of the two air curtain components 3 is connected to the support part 1141 by screws, and the other end is snap-fitted to the snap-fit ​​plate 1142.

[0055] The air curtain bracket 114 is installed on the upper surface of the top plate 11, that is, inside the electrical control cavity 12. The air curtain bracket 114 can support and fix the air curtain assembly 3. Each of the two air curtain brackets 114 has a support part 1141 at the end that is close to each other, and a snap-fit ​​plate 1142 at the end that is far away from each other.

[0056] The two air curtain supports 114 can be defined as the left air curtain support and the right air curtain support, respectively. For the left air curtain support, the snap-fit ​​plate 1142 is located at the left end and the support part 1141 is located at the right end; for the right air curtain support, the snap-fit ​​plate 1142 is located at the right end and the support part 1141 is located at the left end.

[0057] When installing the left air curtain assembly, first slide the left air curtain assembly from the right end to the left end along the left air curtain bracket. After sliding into place, the left end of the left air curtain assembly is engaged with the snap-fit ​​plate 1142 of the left air curtain bracket, and the right end of the left air curtain assembly is aligned with the support part 1141 of the left air curtain bracket. At this time, the right end of the left air curtain assembly can be connected to the support part 1141 of the left air curtain bracket by screws.

[0058] When installing the right air curtain assembly, first slide the right air curtain assembly from the left end to the right end along the right air curtain bracket. After sliding into place, the right end of the right air curtain assembly is engaged with the snap-fit ​​plate 1142 of the right air curtain bracket, and the left end of the right air curtain assembly is aligned with the support part 1141 of the right air curtain bracket. At this time, the left end of the right air curtain assembly can be connected to the support part 1141 of the right air curtain bracket by screws.

[0059] The smoke hood of this utility model, such as Figure 8 As shown, the air curtain support 114 is provided with a clearance opening, which passes through one end of the air curtain support 114 provided with a support part 1141. The support part 1141 is located on the clearance opening, and the clearance opening avoids the bulge formed by the first recess 111 on the top plate 11. The two sides of the clearance opening are provided with walls 1143, and the snap-fit ​​plate 1142 extends from the upper edge of the wall 1143 to the width direction of the clearance opening.

[0060] The upper surface of the top plate 11 has a raised portion corresponding to the first recess 111. The air curtain bracket 114 is connected to the surface of the top plate 11 surrounding the raised portion, which is located within a clearance opening. Thus, the air curtain bracket 114 can bypass the raised portion and connect to the top plate 11 through the clearance opening, achieving stable installation of the air curtain bracket 114 on the top plate 11. The clearance opening also connects the exhaust side of the air curtain assembly 3 to the air curtain exhaust port 1111, allowing the airflow from the air curtain assembly 3 to flow through the clearance opening to the air curtain exhaust port 1111, and then through the air curtain exhaust port 1111 down to form an air curtain below the top plate 11. By providing a clearance opening on the air curtain bracket 114, the raised portion on the top plate 11 can be prevented from affecting the installation of the air curtain bracket 114, thereby improving the overall ease of installation of the air curtain assembly 3.

[0061] The raised portion extends along the length of the top plate 11. In conjunction with the aforementioned embodiments of the left and right air curtain supports, both the left and right air curtain supports have clearance openings. The clearance opening of the left air curtain support extends through the right end of the left air curtain support, and the clearance opening of the right air curtain support extends through the left end of the right air curtain support.
