Description

Technical Field

[0001] This utility model relates to the field of smoke extraction technology, specifically to a smoke extraction structure for a cooking chamber. Background Technology

[0002] In the modern food processing industry, nutritious porridge, as a healthy food rich in various nutrients and easily digestible, is very popular among consumers. The steaming and cooking process of nutritious porridge produces fumes, thus requiring a fume extraction system.

[0003] Existing flue gas purification devices are not ideal for treating the high-temperature flue gas generated during the cooking of porridge. In this flue gas, starch particles adhere to each other, making it easy for impurities to adhere to the filter components during filtration, reducing filtration efficiency. Furthermore, existing filter components are difficult to disassemble for cleaning. Simultaneously, when the high-temperature flue gas encounters the cooler exhaust pipe inlet, condensation occurs. This condensate flows back through the exhaust pipe, potentially returning to the indoor connection to the exhaust pipe or accumulating within the exhaust pipe itself, affecting the performance of the connection or causing dripping indoors.

[0004] Therefore, we propose a smoke exhaust structure for the cooking chamber to address the problems mentioned above. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] The purpose of this invention is to provide a smoke exhaust structure for a cooking chamber to solve the problems currently existing in the market as described in the background.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, this utility model provides the following technical solution: a smoke exhaust structure for a steaming chamber, including a ventilation pipe installed on the steaming chamber, wherein the air inlet of the ventilation pipe is detachably connected to an air inlet pipe, the air outlet of the ventilation pipe is detachably connected to an air outlet pipe, and a one-way valve is provided at the air inlet end of the air inlet pipe.

[0009] The lower end of the ventilation duct is equipped with an air guide and water collection component, and a filter is installed in the middle of the air guide and water collection component. A circulating cooler is installed on the outer wall of the ventilation duct, and a condenser is installed on the circulating cooler. The middle of the condenser is located inside the ventilation duct. A fixing frame is installed at the upper end of the ventilation duct, and a driving component is installed on the fixing frame. A scraper is installed at the output end of the driving component.

[0010] Furthermore, the air guide and water collection component includes a hollow frustum-shaped first air guide cover, a water guide platform is fixedly fitted on the lower outer side of the first air guide cover, and a water collection pipe is connected to the rear end of the water guide platform. The water guide platform is designed to be higher in the front and lower in the back. A hat-shaped second air guide cover is fixed above the middle part of the first air guide cover, and a gap is reserved between the first air guide cover and the second air guide cover.

[0011] The above technical solution allows flue gas to enter the ventilation duct through the first air guide hood and flow through the gap between it and the second air guide hood. The condensed water droplets are collected in the water collection pipe from the water guide platform.

[0012] Furthermore, the filter element includes a threaded tube that is threadedly connected to the inner side of the middle part of the first air guide hood. A filter cylinder is fixed to the upper end of the threaded tube, and a bracket is fixed to the inner wall of the threaded tube. A material discharge trough is installed on the bracket, and the material discharge trough is fixedly installed on the inner wall of the upper end of the threaded tube.

[0013] The above technical solution allows the filter element to be removed from the first air guide cover to clean the impurities in the material discharge trough.

[0014] Furthermore, the condenser fitting includes an output pipe, an input pipe, and several spiral coils. The two ends of the spiral coils are respectively connected to the output pipe and the input pipe. The output pipe is connected to the water outlet of the circulating cooler, and the input pipe is connected to the water inlet of the circulating cooler.

[0015] The above technical solution enables the output pipe to transport the low-temperature coolant of the circulating cooler to the spiral coil. The spiral coil absorbs the heat from the flue gas, and the heated coolant flows back to the circulating cooler through the input pipe to cool down, thus forming a cycle.

[0016] Furthermore, the drive component includes a bevel gear roller mounted inside the fixed frame via bearings, and a bevel gear ring meshes with the side of the bevel gear roller.

[0017] The above technical solution enables the bevel gear roller to rotate when the motor drives it to rotate, which in turn drives the bevel gear ring to rotate.

[0018] Furthermore, the scraping component includes a rotating rod rotatably mounted on the lower center of the fixed frame. The rotating rod is fixedly connected to the center of the bevel ring, and several scraper groups are installed on the side of the rotating rod. The several scraper groups are arranged in a one-to-one correspondence with several spiral coils. Each scraper group includes two scrapers, which are located at the upper and lower ends of the spiral coil, respectively.

[0019] The above technical solution enables the scraper assembly on the rotating rod to scrape away water droplets on the spiral coil after the drive unit is started, thus ensuring the condensation effect.

[0020] 3. Beneficial effects:

[0021] Compared with the prior art, the exhaust structure of the cooking chamber of this utility model, using the technical solution provided by this utility model, guides, filters, and condenses the flue gas to achieve purification and prevents the condensate from flowing back into the room. The specific details are as follows:

[0022] The flue gas generated in the cooking chamber enters the ventilation duct and first passes through the first air guide hood into the filter element in the filter cartridge, which intercepts larger particulate impurities in the flue gas. The impurities fall into the material chute. The filter element is removed from the first air guide hood periodically by rotating the threaded tube through the bracket to clean the impurities.

[0023] After being filtered, the flue gas flows through the gap between the first air guide hood and the hat-shaped second air guide hood. The output pipe delivers the low-temperature coolant from the circulating chiller to the spiral coil. The spiral coil absorbs heat from the flue gas, and the heated coolant flows back to the circulating chiller through the input pipe to cool down, forming a cycle. During this process, water vapor in the flue gas further condenses into liquid water, which adheres to the surface of the spiral coil, forming water droplets. These droplets then fall onto the water guide platform and are collected through the water collection pipe to prevent them from flowing back into the room.

[0024] The drive unit mounted on the fixed frame starts working. The motor drives the bevel gear roller to rotate, which in turn drives the bevel gear ring meshing with its side to rotate. The rotating rod fixed in the middle of the bevel gear ring rotates accordingly, and the scraper group mounted on the side of the rotating rod also rotates together. During the rotation, the condensate and impurities on the surface of the spiral coil are scraped off to ensure the condensation effect of the spiral coil. Attached Figure Description

[0036] Please see Figure 1-6A smoke exhaust structure for a cooking chamber includes a ventilation duct 1 installed on the cooking chamber. The air inlet of the ventilation duct 1 is detachably connected to an air inlet pipe, and the air outlet of the ventilation duct 1 is detachably connected to an air outlet pipe. A one-way valve is provided at the air inlet end of the air inlet pipe. A wind guide and water collector 2 is installed inside the lower end of the ventilation duct 1, and a filter 3 is installed in the middle of the wind guide and water collector 2. A circulating cooler 4 is installed on the outer wall of the ventilation duct 1, and a condenser pipe 5 is installed on the circulating cooler 4. The middle part of the condenser pipe 5 is located inside the ventilation duct 1. The wind guide and water collector 2 includes a hollow frustum-shaped first wind guide hood 21, the lower end of which... A water guide platform 22 is fixedly fitted on the outer side, and a water collection pipe 23 is connected to the rear end of the water guide platform 22. The water guide platform 22 is designed to be higher in the front and lower in the back. A second air guide hood 24 in the shape of a hat is fixed above the middle part of the first air guide hood 21. A gap is reserved between the first air guide hood 21 and the second air guide hood 24. The filter element 3 includes a threaded tube 31 that is threaded to the inner side of the middle part of the first air guide hood 21. A filter cylinder 32 is fixed at the upper end of the threaded tube 31. A bracket 33 is fixed on the inner wall of the threaded tube 31. A material discharge trough 34 is installed on the bracket 33. The material discharge trough 34 is fixedly installed on the inner wall of the upper end of the threaded tube 31.

[0037] The flue gas generated in the cooking chamber enters the ventilation pipe 1 and first enters the filter cylinder 32 in the filter element 3 through the first air guide hood 21. During the flow of flue gas, the filter cylinder 32 intercepts larger particulate impurities in the flue gas. The impurities fall into the material drop trough 34. The filter element 3 is removed from the first air guide hood 21 by rotating the threaded pipe 31 through the bracket 33 periodically to clean the impurities.

[0038] After being filtered, the flue gas flows through the gap between the first guide hood 21 and the hat-shaped second guide hood 24. The output pipe 51 delivers the low-temperature coolant from the circulating cooler 4 to the spiral coil 53. The spiral coil 53 absorbs heat from the flue gas, and the heated coolant flows back to the circulating cooler 4 through the input pipe 52 to cool down, forming a cycle. During this process, the water vapor in the flue gas further condenses into liquid water, which adheres to the surface of the spiral coil 53, forming water droplets. These droplets then fall onto the water guide platform 22 and collect in the water collection pipe 23. The bottom of the water collection pipe 23 is connected to an external collection box via a pipe to collect the condensate.

[0039] A fixed frame 6 is installed at the upper end of the ventilation pipe 1, and a driving component 7 is installed on the fixed frame 6. A scraper 8 is installed at the output end of the driving component 7. The condenser pipe 5 includes an output pipe 51, an input pipe 52, and several spiral coils 53. The two ends of the spiral coils 53 are connected to the output pipe 51 and the input pipe 52, respectively. The output pipe 51 is connected to the water outlet of the circulating cooler 4, and the input pipe 52 is connected to the water inlet of the circulating cooler 4. The driving component 7 includes a bevel gear roller 71 installed inside the fixed frame 6 through a bearing. A bevel gear ring 72 meshes with the side of the bevel gear roller 71. The scraper 8 includes a rotating rod 81 rotatably installed below the middle of the fixed frame 6. The rotating rod 81 is fixedly connected to the middle of the bevel gear ring 72. Several scraper groups 82 are installed on the side of the rotating rod 81. Several scraper groups 82 are arranged one-to-one with several spiral coils 53. Each scraper group 82 includes two scrapers, which are located at the upper and lower ends of the spiral coils 53, respectively.

[0040] Start the motor connected to the end of the bevel gear roller 71 to drive the bevel gear roller 71 to rotate, which in turn drives the bevel gear ring 72 meshing with its side to rotate. The rotating rod 81 fixed in the middle of the bevel gear ring 72 rotates accordingly, and the scraper group 82 installed on the side of the rotating rod 81 also rotates together. During the rotation, the condensate and impurities on the surface of the spiral coil 53 are scraped off to ensure the condensation effect of the spiral coil 53.

[0041] Working principle: When using the exhaust structure of this cooking chamber, such as Figure 1-6 As shown, firstly, the ventilation pipe 1 is installed on the exhaust port of the cooking chamber. The one-way valve on the air inlet pipe is opened, and the flue gas generated in the cooking chamber enters the ventilation pipe 1. First, it passes through the filter cartridge 32 to intercept larger particulate impurities in the flue gas. The impurities fall into the material trough 34 and are periodically disassembled and cleaned. Then, the flue gas flows through the gap between the first air guide hood 21 and the hat-shaped second air guide hood 24. It absorbs the heat of the flue gas through the spiral coil 53 to achieve cooling. At the same time, the drive component 7 works, driving the scraper group 82 on the rotating rod 81 to scrape off the water droplets attached to the surface of the spiral coil 53 to ensure the condensation effect. Then, the water is collected through the water collection pipe 23.
