The main author of this creation is the exhaust fume device < n spoon, which is to solve the above problem. The configuration of the fan is changed. 4 rows of fume are installed inside. There is a good mouth for connecting _ ,, " Government fan, 5 When the blower is set to connect the box 5 2, the fan wheel 5 6 is shown in Figure 6, but it increases the volume by 55, and when the fan 7 is inside, it is arranged in the row as the 7th. The range hood 7 6 must be bent at ninety degrees. The extension amount will be bent by the exhaust pipe 6 and the motor 5 booster port must be added. The structural design problem and configuration effectively reduce the overall volume of the blower. The problem is provided _ _ It includes a row of oil fume. The blower has -4 ^ exhaust and the blower is based on this. M241607 -------- Fifth, the creation description is placed inside, so that the air outlet of the blower system extends to the room, and the volume under the circumstances. This invention therefore the drum and the 5 Hai blast will be increased by the exhaust of the beard, the overall result is [the implementation of the embodiment please refer to the example of the structure of the invention includes ^ 1 2 'the drum one exhaust pipe 3 Nozzle exhaust fume (3) The exhaust air is diagonally arranged outside the exhaust air, so that it can be smoothly discharged. It can be used as the shell of the secondary fan. limit. A row of oil fume fans 2 3 extension diameters are placed together 1 The rear tube can be flexibly placed on the oil fume skirt tube without bending the ninety of the blower out of the blower, thereby enabling the drum to achieve the required exhaust air purpose The reason is that the outer wall and the fan blade system of the exhaust vent are arranged in parallel to block the wall of the shell, so that the wind does not need to increase the motor to reduce the arc of the blower. . Because the heart makes the blower connected to the blower can have a larger bending radian = the resistance of the Yiyi to the exhaust pipe ~ the motor can be relatively reduced without adding horses, the volume of the blower fan can be reduced, the shell wall is relatively reduced, and the air volume is sent straight Without loss, and when the volume is reached, the volume of the motor will not be reduced, and the blower diagram can be reduced to Figure 3. The ones shown in the figure are selected for the creation. This is for illustration only. The configuration of the blower, which is not affected by such an oil fume exhaust device, is improved. The device 1 is provided with an air blower 2 having a fixed caliber exhaust port 2 1 for connection to the outdoor. The air exhaust port 2 1 The caliber is related to the exhaust air, and the blower 2 is arranged in the exhaust fume device 1 in an oblique direction toward the exhaust port 21, so that

M241607 V. Creation instructions (4) The exhaust duct 3 can be extended to the outdoors with a large bending arc. The blower 2 has a casing 2 2, and the upper end of the casing 22 has an exhaust port 2 1 of the fixed caliber. A peripheral edge of the exhaust port 2 1 protrudes upward from a flange 2 3 for connecting the exhaust pipe 3. A motor 2 4 is provided in the housing 22, and a fan wheel 2 5 is provided on each of the two sides of the motor 2 4. The fan blades 2 5 1 of each fan wheel 2 5 are arranged in parallel and each The fan wheel 2 5 is driven by the motor 24 to rotate, and the casing 22 is provided with an air inlet 2 6 on the two sides corresponding to each of the fan wheel 2 5 for oil fume to enter. Thereby, when the motor 24 in the blower 2 is running, the motor 24 will drive the two blower wheels 25 to rotate, so that the oil fume is sucked in by the air inlets 26 on both sides of the casing 2 2 and then by the The exhaust port 21 of the casing 22 is sent out through the exhaust pipe 3 to achieve the purpose of excluding oil smoke. Since the blower 2 is arranged obliquely in the fume exhausting device 1, the exhaust pipe 3 connected to the exhaust port 21 of the blower 2 does not need to be bent at 90 degrees, but can be extended to the outside with a large bending arc. Makes the air volume discharged by the blower 2 difficult to be blocked by the exhaust pipe 3, and can be smoothly discharged, so that the motor 24 of the blower 2 can reach the required air volume without increasing the horsepower. In actual testing Below, the blower of the same horsepower motor is used as a test comparison. Figure 4A is the test data and charts of the configuration structure of this creative, and Figure 4B is the test data and charts of the conventional configuration structure. The maximum air volume can reach 6 6 2 · 4 6 Μ Η, and the conventional air volume can reach up to 59 5 · 50CMH. The difference between the two is about 70 C Μ Η. Therefore, in the case of no increase in horsepower,

Page 7 M241607 V. Creative Instructions (5) The required exhaust air volume can be achieved, and a smaller horsepower motor 2 4 can be used to reduce the volume of the motor 24, which can relatively reduce the volume of the blower 2. Furthermore, since the volume of the blower 2 can be reduced, the shell wall between the casing 22 and the exhaust port 21 of the blower 2 will be relatively reduced, and the blades 2 5 1 of the blower wheel 2 5 are arranged in parallel. , So that the air volume is sent straight without being hindered by the shell wall of the housing 22, so that the air volume will not be lost. When the required air volume is reached, the horsepower of the motor 24 does not need to be increased, so that the volume of the motor 24 does not increase. It will increase, and the volume of the blower 2 can be reduced relatively, thereby reducing the cost of the blower as a whole. The disclosure of the embodiments described above is used to explain the creation, and is not intended to limit the creation. Therefore, any numerical change or replacement of equivalent components should still belong to the scope of the creation. From the above detailed description, those skilled in the art can understand that this creation can indeed achieve the aforementioned purpose, and it has indeed complied with the provisions of the Patent Law, and filed a patent application.
