Description

Technical Field

[0001] The invention belongs to the technical field of smoke exhaust, and in particular relates to a smoke exhaust flow control valve for a smoke hood integrated machine. Background Art

[0002] With the acceleration of urbanization and the improvement of people's living standards, the functionality and environmental protection of the kitchen, as the core area of ​​family life, are increasingly valued. In the cooking process, the generation of oil fume is inevitable, and the effective removal of oil fume is crucial to maintaining the air quality of the kitchen and protecting the health of the cook. Although the traditional all-in-one hood has played a certain role in oil fume emission, its exhaust flow control mechanism often has many shortcomings.

[0003] At present, in the process of smoke exhaust, the smoke exhaust flow control valve of the traditional integrated smoke hood machine has obvious deficiencies in the flow regulation mechanism, and fails to realize the adaptive regulation function according to the change of oil fume concentration and the actual working wind force of the smoke exhaust machine. This defect causes the flow control valve to be unable to accurately and dynamically adjust its opening degree according to the size of the oil fume, thereby causing the problem of low oil fume emission efficiency, seriously affecting the effect of oil fume purification and the improvement of kitchen air quality. In addition, the flow control of the traditional integrated smoke hood machine usually relies on manual adjustment or simple mechanical switches. This control method is not only cumbersome to operate, but also difficult to realize intelligent management. With the growing demand for intelligence and automation in modern kitchens, this control method of traditional equipment can no longer meet the needs of modern kitchens; therefore, it is insufficient and cannot meet the user's usage needs. Therefore, it is necessary to further improve it.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a smoke exhaust flow control valve for a smoke hood integrated machine is provided, in order to achieve a more practical purpose. Summary of the invention

[0069] The specific usage and function of this embodiment are as follows:

[0070] Working principle: When cooking in the kitchen generates oil smoke, the control panel 13 is operated to drive the exhaust fan 14 to generate kinetic energy and start running. The exhaust fan 14 generates a strong suction force to suck the oil smoke into the exhaust pipe 15. As the oil smoke is sucked in, the wind force it carries directly acts on the sealing block 343, pushing the sealing block 343 and the inner wall of the sealing sleeve 31 to produce relative displacement, thereby forming a gap. The oil smoke passes through these gaps smoothly and enters the sealing part 32. In the process of moving, the sealing block 343 pushes the spiral rod 42 to move synchronously. As the spiral rod 42 continues to move, the threaded rotation of the spiral rod 42 and the spiral sleeve 441 can drive the transmission toothed disc 44 to rotate, and the transmission toothed disc 44 is meshed with the gear ring 54 for transmission, driving the gear ring 54 to drive the movable disc 52 to rotate synchronously. During the rotation of the movable disc 52, the guide column 531 on one side of the sealing plate 53 slides in the first guide groove 511 on the valve seat 51, and the sealing plate 53 The convex block on the other side slides in the second guide groove 521 on the movable disk 52, thereby driving the sealing plate 53 to produce relative displacement and open the smoke exhaust channel, thereby realizing the automatic opening of the sealing plate 53; and through this setting, the moving stroke of the sealing block 343 is proportional to the wind force of the oil smoke. The greater the wind force, the farther the sealing block 343 is pushed, and the greater the force transmitted by the transmission component 40, thereby driving the sealing plate 53 on the valve component 50 to open to a greater extent, allowing more oil smoke to pass through; on the contrary, when the wind force is small, the moving stroke of the sealing block 343 is short, and the opening degree of the sealing plate 53 is also reduced accordingly, thereby realizing fine control of the oil smoke flow rate, and the movement of the sealing block 343 driven by wind force is realized. Adaptive adjustment of the opening degree of the valve component 50 is realized, and the opening of the smoke exhaust channel can be automatically adjusted according to the concentration of the oil smoke and the wind force, ensuring smooth and efficient oil smoke discharge, further ensuring the dynamic balance between the oil smoke flow rate and the smoke exhaust capacity, and effectively improving the smoke exhaust efficiency;

[0071] In addition, the oil smoke passes through the sealing part 32 and enters the cleaning mechanism 60. The electrode plate 62 utilizes its electrostatic adsorption characteristics to effectively adsorb particulate matter in the oil smoke. At the same time, the cleaning blade 63 is driven to rotate under the action of wind. When the cleaning blade 63 rotates, the cleaning main rod 641 drives the cleaning connecting rod 642 to rotate synchronously. The cleaning connecting rod 642 drives the cleaning scraper 644 to clean the oil smoke particles on the surface of the electrode plate 62. In the process of the cleaning connecting rod 642 driving the cleaning scraper 644 to clean the oil smoke particles, the cleaning connecting rod 642 also drives the knocking component 66 Synchronous movement, based on the force of the knocking assembly 66 when rotating, the rotating knocking member 664 will come into contact with the fixed protrusion 651 on the fixed frame 65, so that the knocking clamp 662 generates a vibration frequency under the elastic force of the vibration spring 663, and the vibrating knocking clamp 662 is used to vibrate and knock the cleaning scraper 644, so that the cleaning scraper 644 synchronously generates a vibration frequency, so that the cleaning scraper 644 continuously changes the scraping direction while working, so as to more comprehensively remove the oil fume particles, and the scraped oil fume particles are collected in the collection box for subsequent processing;

[0072] Finally, when the smoke exhaust fan 14 stops running, the sealing block 343 automatically resets under the elastic force of the elastic support pad 342, driving the sealing block 343 to fit tightly against the inner wall of the sealing sleeve 31, thereby sealing the smoke exhaust pipe 15. At the same time, the transmission assembly 40 also drives the sealing plate 53 in the valve assembly 50 to automatically reset, forming an effective sealing barrier, ensuring the sealing of the entire smoke exhaust system, preventing oil fume leakage, and thereby ensuring the cleanliness and hygiene of the kitchen environment.
