Technical Field

[0001] The utility model relates to the technical field of smokeless switching, in particular to a smokeless switching device for a baking oven. Background Art

[0002] An oven is a device that uses hot air to bake and cook food. It is generally a closed or semi-closed structure. An oven can also be used to refer to a device that uses hot gas for high-temperature processing. Traditional ovens use wood or coal for heating, while modern ovens are multifunctional and use electric heating or natural gas. During the use of the oven, different methods of exhausting oil smoke are used according to the needs of the environment. For this purpose, a smokeless switching device is used.

[0003] In current life, the oven is placed separately, resulting in only smoke emission when the oven is used outdoors, which affects the surrounding environment and makes the oven unsuitable for different environments. Based on this, the utility model designs a smokeless switching device for the oven to solve the above problem. Utility Model Content

[0025] See also Figure 1-4 The utility model provides a technical solution: a smokeless switching device for an oven, comprising a switching box 1, a blowing fan 6 fixedly connected to the bottom of the switching box 1, an air inlet pipe 7 mounted on the bottom of the blowing fan 6 by screws, a smoke outlet pipe 8 mounted on one end of the switching box 1 by screws, and a smokeless outlet pipe 9 mounted on the other end of the switching box 1 by screws;

[0026] One end of the switch box 1 is rotatably connected to a rotating shaft 2, and a rotating frame 3 is fixedly sleeved on the outside of the rotating shaft 2. Spring telescopic columns 4 are evenly installed inside the rotating frame 3 by screws. One end of several adjacent spring telescopic columns 4 is connected by a movable plate 5. The end face of the movable plate 5 contacts the inner wall of the switch box 1. The end of the movable plate 5 is provided with an arc angle to facilitate closing the inner wall of the switch box 1. A rotating plate 10 is welded to one end of the rotating shaft 2. A latch 11 is slidably connected to the inside of one end of the switch box 1. The latch 11 passes through the rotating plate 10. The longitudinal section of the latch 11 is convex, which is convenient for fixing the rotating plate 10 and then fixing the rotating shaft 2.

[0027] A mounting plate 12 is installed at one end of the smokeless air outlet duct 9 by screws, and a sealing frame 13 is bonded to the end face of the mounting plate 12. Mounting grooves 14 are evenly opened at one end of the mounting plate 12, and a mounting rod 15 is slidably connected inside the mounting groove 14. A filter screen 16 is installed at one end of the three mounting rods 15 by screws. The mounting groove 14 includes a rectangular groove and a T-shaped groove. A rectangular groove is evenly opened at the end face of the mounting plate 12, and a T-shaped groove is opened at the bottom surface of the rectangular groove. The outer diameter of the mounting rod 15 is equal to the inner diameter of the mounting groove 14, which is convenient for the installation and disassembly of the filter screen 16 and the activated carbon adsorption plate 17. The activated carbon adsorption plate 17 is installed at one end of the two mounting rods 15 by screws.

[0028] When the operator is using the oven, the operator installs the smokeless switching device on the top of the oven by screws. According to the needs, the operator rotates the rotating plate 10, thereby driving the rotating shaft 2 to rotate. The rotation of the rotating shaft 2 drives the rotating frame 3, the spring telescopic column 4 and the movable plate 5 to rotate. By using the spring telescopic column 4, the movable plate 5 can always be in contact with the inner wall of the switching box 1. After the rotating frame 3 and the movable plate 5 are rotated to the appropriate position, the operator fixes the rotating plate 10 by the latch 11, thereby guiding the oil smoke in time. When smoke can be discharged, the oil smoke can be discharged from the smoke outlet pipe 8. When smokeless discharge is required, the oil smoke is discharged through the smokeless outlet pipe 9. At this time, the impurities in the oil smoke are adsorbed by the filter 16 and the activated carbon adsorption plate 17, the concentration of the oil smoke is reduced, thereby realizing smokeless switching, facilitating rapid switching between smoke and smokeless, thereby making the oven suitable for different positions, expanding the scope of application of the oven;

[0029] When personnel need to remove the filter 16 and the activated carbon adsorption plate 17, they can remove the mounting plate 12, then move the filter 16 and the activated carbon adsorption plate 17, and take out the mounting rod 15 from the mounting groove 14, which makes it easier for personnel to install and remove the filter 16 and the activated carbon adsorption plate 17, thereby improving the efficiency of removing and cleaning the filter 16 and the activated carbon adsorption plate 17.
