Embodiment 1

[0040] refer to Figure 3-4 , an embodiment of the present invention provides an image forming apparatus, including an exhaust device 100 and a fixing device 200 .

[0041] The exhaust device 100 includes an air suction duct 110 , an air exhaust port 110 a located at one end of the air suction duct 110 , and an exhaust fan 120 disposed downstream of the air exhaust port 110 a along the air flow direction. The air suction duct 110 extends along the length direction of the fixing device 200 , and its other end opposite to the air outlet 110 a is closed. Wherein, the area of ​​the air outlet 110a is smaller than the cross-sectional area of ​​the inner wall of the air suction duct 110 .

[0042] In this embodiment, the air suction duct is in the shape of a cuboid and has a bottom surface 111 facing the fixing device 200. A suction area is provided on the bottom surface 111. The air flow can pass through the air suction area and then be discharged through the air outlet 110a, as s...

Embodiment 2

[0062] refer to Figure 9-10 , the first area Q1 is provided with air suction holes 111a, while the second area Q2 is not provided with air suction holes, the difference from Embodiment 1 is that all the air suction holes 111a have a uniform diameter.

[0063] In this example, if Figure 10 , the diameters of all the suction holes 111a are unified to 4mm.

[0064] In this embodiment, the apertures of the air suction holes 111a are of the same size, that is, the impedance at each air suction hole 111a is the same, and the suction force generated by the exhaust fan 120 preferentially affects the air at the proximal end B, and its consumption at the proximal end is compared with that in the implementation. Example 1 is increased, so the suction force distributed to the distal end A is reduced compared to Example 1.

[0065] At this moment, the wind power of the exhaust device at each position is analyzed by CAE (except for the air suction hole, all the other analysis conditions...

Embodiment 3

[0068] refer to Figure 11-12 , in this embodiment, the arrangement of the air suction holes 111a on the first area Q1 is the same as that of Embodiment 1, the difference from Embodiment 1 is that, refer to Figure 11 As shown, a number of air suction holes 111a' are added in the second area Q2 corresponding to the end of the bottom surface 111 along the extending direction of the air suction duct away from the air exhaust port.

[0069] At this moment, the wind power of the exhaust device at each position is analyzed by CAE (except for the air suction hole, all the other analysis conditions are the same as in Embodiment 1), and it is obtained as follows Figure 12 The suction effect diagram shown.

[0070] According to the analysis results, it can be seen that the wind force at the far end A and the near end B are basically the same, the maximum wind force is between 0.062-0.071m / 3min, and the wind force in the middle is basically between 0.053-0.062m / 3min. That is to say, ...

Abstract

The invention discloses an air exhausting apparatus used for an image formation apparatus and the image formation apparatus. The air exhausting apparatus comprises an air suction pipeline, wherein an air exhausting opening is formed in one end of the air suction pipeline and used for arranging an exhaust fan; the air suction pipeline is divided into a first region and a second region along the radial direction; the region where the air exhausting opening extends and passes through along the extension direction of the air suction pipeline is the second region; the first region is staggered from the air exhausting opening; an air suction region for allowing air flow to pass through is arranged on the circumferential wall of the air suction pipeline; the area of the air suction region in the first region is larger than the area of the air suction region in the second region; and the downstream of the air suction region is used for arranging the exhaust fan along the air flowing direction. According to the air exhausting apparatus provided by the invention, the air suction capability of the exhaust fan to the far end can be optimized, so that an effect of discharging dust and heat at the far end out of the air suction pipeline can be realized.

Description

technical field [0001] The invention relates to an exhaust device for an image forming device and the image forming device. Background technique [0002] The image forming apparatus generally includes: an image forming unit for forming a toner image on a recording medium (such as paper); a fixing unit for thermally fixing the toner image formed on the recording medium, wherein the thermal fixing process Dust and a large amount of heat are generated; an exhaust portion for discharging the dust and heat near the fixing portion to the outside of the image forming apparatus through a discharge path together with air. [0003] Japanese Patent Application Publication No. JP2014044238A discloses an image forming device, such as Figure 1-2 As shown, it includes a fixing part 5 and an exhaust part 9. The fixing part 5 includes two fixing rollers 51 and 52 pressed against each other along the radial direction. , 52 accommodating parts. The accommodating portion has an inlet and an ...
