Description

Technical Field

[0001] This utility model relates to the field of steaming equipment technology, and more specifically, to a smoke collection hood structure for steaming equipment. Background Technology

[0002] Steaming equipment uses steam to steam food inside the equipment. When a large amount of high-temperature steam is generated in the steaming equipment, it can lead to excessive air pressure and humidity inside the equipment, which may pose safety hazards and affect the taste of the food. Therefore, a fume hood structure is needed to remove the steam in a timely manner.

[0003] Existing fume hoods typically have an air pump installed at the top for extraction, and the inside of the fume hood usually has a mesh plate for separating steam and water. However, when the steam inside the steaming equipment is too large, a single mesh plate is insufficient to completely separate the moisture in the steam, resulting in excessive moisture in the steam after passing through the mesh plate. After prolonged operation, this can easily damage the air pump. In addition, during the fume hood's exhaust process, the separated moisture can drip onto the food, affecting its taste.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a smoke collection hood structure for a steaming device in order to solve the above-mentioned problems.

[0006] The above-mentioned technical objective of this utility model embodiment is achieved through the following technical solution: a smoke collection hood structure for a steaming equipment, including a frame body and an air pump, smoke collection hoods are provided on both sides of the frame body, an air outlet pipe is fixedly connected to the smoke collection hood, the air outlet pipe is fixedly connected to the air pump, a first mesh plate that rotates with the smoke collection hood and a second mesh plate that is fixedly connected to the smoke collection hood are provided inside the smoke collection hood, the second mesh plate is located above the first mesh plate, a driving mechanism for driving the first mesh plate to rotate is provided on the smoke collection hood, a collecting device is provided at the lower end of the smoke collection hood located at the first mesh plate, and a pressure gauge is provided on the outer side of the smoke collection hood.

[0007] The present invention is further configured such that: the first mesh plate includes a left mesh plate and a right mesh plate, the ends of the left mesh plate and the right mesh plate that are close to each other are rotatably engaged with the smoke collection hood, and the ends of the left mesh plate and the right mesh plate that are far from each other abut against the inner wall of the smoke collection hood; the driving mechanism includes a driving rod that is fixedly connected to the right mesh plate, a driving gear that is fixedly connected to the driving rod, and a driven gear that is fixedly connected to the left mesh plate; the driving gear and the driven gear mesh with each other.

[0009] The present invention is further configured such that both the first mesh plate and the second mesh plate are inclined and staggered.

[0010] The present invention is further configured such that: the collecting device includes an inclined plate fixedly connected inside the smoke hood, and a collecting groove is fixedly connected to the lower end of the inclined plate.

[0011] The present invention is further configured such that: a drain pipe is provided in the collection trough, and the drain pipe extends out of the smoke collection hood.

[0012] In summary, this utility model has the following beneficial effects:

[0013] By installing a first mesh plate and a second mesh plate distributed vertically inside the fume hood, the first and second mesh plates can fully condense the moisture in the steam when the fume hood is working, ensuring the mesh plates' isolation effect on moisture. This reduces the humidity in the steam after passing through the mesh plates, minimizing damage to the suction pump. When the steam concentration inside the steaming equipment is high, the first mesh plate can be rotated and adjusted by a drive mechanism to increase the steam flow area, allowing the steam to be discharged quickly. At the same time, by installing a collection device at the lower end of the first mesh plate, the moisture condensed by the first and second mesh plates will fall into the collection device, effectively preventing moisture from falling into the food and resulting in better quality steamed food.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] In one possible embodiment, please refer to Figure 1 and Figure 3 As shown, a smoke hood structure for a steaming equipment includes a frame body 1 and an air pump 2. Smoke hoods 3 are provided on both sides of the frame body 1. An exhaust pipe 4 is fixedly connected to the smoke hood 3 and is fixedly connected to the air pump 2. The air pump 2 extracts excess steam from the steaming equipment, reducing the increase in ambient humidity caused by excessive steam, thus improving the taste of steamed food. Inside the smoke hood 3, there is a first mesh plate that rotates with the smoke hood 3 and a second mesh plate 6 that is fixedly connected to the smoke hood 3. The second mesh plate 6 is located above the first mesh plate, and the side wall of the first mesh plate abuts against the inner wall of the smoke hood 3. When the smoke hood 3 is working, the first mesh plate and the second mesh plate 6 can fully condense the moisture in the steam, ensuring the isolation effect of the mesh plate on the moisture, thereby reducing the humidity in the steam after it has passed through the mesh plate and reducing damage to the air pump 2.

[0022] For further details, please refer to Figure 1 , Figure 2 and Figure 3 As shown, a pressure gauge 7 is installed on the outside of the smoke hood 3, and a drive mechanism is installed on the smoke hood 3 to drive the first screen plate to rotate. When the steam concentration inside the steaming equipment is high as observed by the pressure gauge 7, the first screen plate is rotated and adjusted by the drive mechanism to increase the steam flow area and allow the steam to be discharged quickly. The first screen plate and the second screen plate 6 are both inclined and staggered. The staggered arrangement of the screen plates ensures that when the first screen plate rotates, the flowing steam will fully contact and condense with the second screen plate 6, thereby effectively reducing the moisture content in the steam after passing through the second screen plate 6.

[0023] For further details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the first mesh plate includes a left mesh plate 8 and a right mesh plate 9. Both the left mesh plate 8 and the right mesh plate 9 are rotatably engaged with the smoke collection hood 3. The ends of the left mesh plate 8 and the right mesh plate 9 that are close to each other are rotatably engaged with the smoke collection hood 3, while the ends of the left mesh plate 8 and the right mesh plate 9 that are far apart from each other abut against the inner wall of the smoke collection hood 3. The driving mechanism includes a driving rod 10 fixedly connected to the right mesh plate 9. One end of the driving rod 10 extends out of the smoke collection hood 3 and is fixedly connected to a crank handle 13. A driving gear 11 is fixedly connected to the driving rod 10, and a driven gear 12 is fixedly connected to the left mesh plate 8. The driving gear 11 and the driven gear 12 mesh with each other. When the air pressure inside the steaming equipment is too high, the crank handle 13 located outside the smoke collection hood 3 is cranked to reduce the pressure. The rotation of the drive rod 10 causes the drive gear 11 to rotate, which in turn drives the driven gear 12 meshing with the drive gear 11 to rotate. This causes the left mesh plate 8 and the right mesh plate 9 to rotate synchronously in opposite directions, separating the ends of the left mesh plate 8 and the right mesh plate 9 from the inner wall of the smoke hood 3, thereby increasing the steam flow area and accelerating the discharge of steam from the smoke hood 3. The smoke hood 3 is provided with a limit block 17, which has a limit groove 18 that engages with the crank handle 13. After the crank handle 13 is rotated, the crank handle 13 engages with the limit groove 18, thereby ensuring the stability of the left mesh plate 8 and the right mesh plate 9.

[0024] For further details, please refer to Figure 3 As shown, a collection device 5 is provided at the lower end of the first mesh plate in the smoke hood 3. The collection device 5 includes an inclined plate 14 fixedly connected inside the smoke hood 3. A collection trough 15 is fixedly connected to the lower end of the inclined plate 14. Under the action of the air pump 2, the steam in the smoke hood 3 will flow upward and condense upon contact with the first mesh plate and the second mesh plate 6. The condensed water will drip into the collection trough 15 under the action of gravity for collection, thereby effectively preventing water from dripping into the steamed food and affecting the quality of the food. A drain pipe 16 is provided in the collection trough 15. The drain pipe 16 extends out of the smoke hood 3, so that the water in the collection trough 15 can be discharged in time through the drain pipe 16.
