In use, the existing water cascade type range hood is installed indoors, and the indoor fume is sucked by the air extracting device 12, and the water at the bottom of the sump 13 is taken out by the water pump 16 and the water sprinkling pipe 15 is used. The spray chambers 14 cooperate to form a water waterfall to flush the oily particles in the soot into the sump 13, thereby preventing the oil particles from being directly discharged outside. # However, the existing water cascade type range hood 1 washes the soot by the waterfall, so some oil particles will still be discharged outside through the gap of the waterfall. Moreover, the existing water cascade type range hood 设置 is installed indoors, and the air extracting device 12 is evenly disposed directly on the casing, so that a large humming sound is generated during operation, which affects the quality of living. Therefore, in order to improve the shortcomings of the existing water-saving range hood, some manufacturers have proposed the patent case of "Water-washing fume filter" issued by Taiwan No. M367311.

In use, a range hood 3 disposed indoors sends soot from the soot inlet hole 213 into the filter drum 21, and the oil particles are washed by the water mist generated by the water mist device 23 and collected in the filter. Make up the bottom of 21. Oil particles that are partially directed upward through the water mist are adsorbed onto the filter screen 22, thereby reducing the contamination of the oil particles by the discharge holes 212 from the outside of the filter drum 21 to cause air pollution. However, some of the oily particles can still exit the filter drum 21 from the discharge hole 212 as the airflow passes through the gap of the filter screen 22. In addition, the oil particles quickly fill the filter holes of the filter screen 22, and the air filter 22 is clogged and the air flow cannot be discharged. The filter 22 must be frequently replaced to maintain normal operation. Moreover, the range hood 3 is installed indoors, so that it is still impossible to improve the noise generated during operation. Although this / Tianhuo Feng machine 2 has slightly improved the problem of poor performance of the current water-explosive range hood, some oily particles will still be discharged through the gap of the over-net U, and the thin 22 Ten = easy to be blocked by oil particles ' must be replaced frequently to maintain normal operation. The range hood 3 in (10) still produces a voice during operation and improves the adverse effects on the quality of life. Good H, so it is necessary to lack the above. 201131125 [Summary of the Invention] Therefore, the object of the present invention is to provide a centrifugal spray hood having a good degreasing effect and being quiet. Therefore, the centrifugal spray range hood of the present invention comprises a pipe body, a water mist unit disposed in the pipe body, a degreasing unit disposed in the pipe body, and a device for driving the water mist unit and In addition to the drive unit.

The effect of the invention is that: #The fan is used to draw the oil fumes into the tube body, and the oil mist is blocked by the defogging unit of the degreasing unit, and the oily water mist is transferred by the centrifugal force generated by the rotation. The cockroach is discharged to the oil collecting groove in the surrounding wall, and the oily sewage flows into and is collected in the bottom sump of the sump, and the clean air after the oil particles are filtered out is discharged to the outside by the venting section. [Embodiment] The foregoing and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of FIG. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. Referring to Figure 3, a first preferred embodiment of the hybrid spray hood of the present invention comprises a tubular body 4, a water mist unit 5, a degreasing unit 6, and a drive unit 7. The tubular body 4 includes a surrounding wall 41 having a toroidal sump 411, a passage 42 defined by the surrounding wall 41, and a discharge conduit 43 formed at the opposite end of the sump 411. The surrounding wall 41 further has an air inlet section 412 and an exhaust section 413 respectively located on both sides of the oil collecting tank 411. The bottom portion of the air inlet portion 412 is inclined toward the oil sump 411. The anti-backflow surface 414' can guide the oil-containing water to flow into the oil collecting groove 411 from the air inlet portion 412 by the backflow prevention. Referring to FIG. 3 and FIG. 4', the water mist unit 5 includes a plurality of spray heads 51 disposed on the air inlet section 412 of the pipe body 4 to generate water mist, one disposed on the pipe body 4 and connected to the spray head. The cleaning solvent tank 52 of the mist head 51 and a water pipe 53 connected to the cleaning solvent tank 52. In the present embodiment, the detergent solvent tank 52 can accommodate a detergent having a degreasing function to cause the spray head 51 to eject a mist containing a detergent, thus enhancing the cleaning effect. Of course, it is also possible to cause the spray head 51 to discharge only water without adding a detergent. Referring to FIG. 3, the degreasing unit ό includes a fan 61 rotatably disposed in the tube body 4 and located in the exhaust section 413 to draw soot and water mist into the passage 42, and a fan 61 The fan 61 rotates and is disposed at the 201131125 degreasing member 62 in the oil collecting groove 411. In the present embodiment, the fan 61 in the form of a turbine is used for description. This type of fan 61 can generate a large suction force. Of course, other types of fans can be used as the conversion, and not limited thereto. 6, the defogging member 62 of the deoiling unit 6 has a frame 621 connected to the fan 61, and a mesh body 622 (see FIG. 6) disposed on the frame 621. In the present embodiment, the metal mesh 622 is used as a description, since the oil particles are less likely to adhere to the metal material. Therefore, the metal mesh body 622 is excellent in durability. Of course, the mesh body 622 may be made of plastic, filter cotton, cardboard or other materials depending on the actual use, or may be made into a composite structure by using two or more materials. In addition, in the embodiment, the mesh body 622 is detachable, so that the mesh body 622 of different materials can be replaced to achieve different transition effects. Referring to FIG. 3, the driving unit 7 includes a motor 71 disposed on the exhaust section 413 of the pipe body 4 for driving the fan 61 to operate, and a motor 71 for controlling the motor and the spray head 5 Open and close control switch 72. In the present embodiment, the fan η is driven by the motor 71. Since the method of driving the fan 61 is well known to those skilled in the art, the motor 71 is illustrated in a schematic manner in Fig. 3. In use, the control switch 72 is first turned on and the motor 71 is activated to drive the fan 61 to rotate. After the fan 61 rotates and generates an air flow to draw the soot from the air inlet section 412 into the passage 42, the spray The mist head 51 then generates a water mist in the air inlet section 412 of the passage 42, thereby mixing the oil stain particles in the oil smoke with the water mist to form an oily water mist, and some oily water 7 201131125 will condense directly after the mist is liquefied and It is dropped onto the backflow prevention surface 414, and flows into the bottom of the oil collecting tank 411 via the inclined design of the backflow prevention surface 414, and flows into the discharge duct 43. The remaining oily mist that is not condensed and dropped will be driven by the airflow to continue to flow forward, and is prevented from adhering to the mesh body 622 (see FIG. 6) of the oil misting member 62, since the oil misting member 62 is Because the fan is interlocked and is in a rotating state, the oily sewage can be further removed to the inner wall surface of the oil collecting tank 4 by the centrifugal force generated by the high-speed rotating deoiling member 62, and then the liquefied oily sewage is liquefied. It will flow into the discharge duct 43 along the inner wall surface of the oil collecting groove 41 to be discharged or collected. The clean air from which the oil particles are removed by the above-described treatment is discharged to the outside through the exhaust section 413, thereby preventing the soot from being directly escorted to the outside to cause air pollution. Further, a detergent capable of removing oil stains, such as dishwashing detergent, may be added to the cleaning solvent tank 52, whereby the water mist sprayed by the spray head 5] may have a cleaning function and can be further improved. The water mist removes the effect of the oil particles' and can simultaneously clean the grease adhering to the inner wall surface of the pipe body 4, the defogging member 62, and the fan 61 to improve the overall service life.
