The oil smoke separator 2 is arranged between an upper section of flue 6 and a lower section of flue 6, the lower end of the upper flue and the upper end of the lower flue are fixedly provided with a rotary connecting structure 3, the inside of the rotary connecting structure 3 is as shown in figure 5, a tubular through groove is fixedly arranged on the rotary connecting structure 3, one end of the tubular through groove is fixedly provided with a waterproof bearing 33, the external structure of the oil smoke separator 2 is shown in fig. 4, the oil smoke separator 2 comprises an upper shell 4, a lower shell 5 and two flue connecting pipes 1, the upper shell 4 and the lower shell 5 are funnel-shaped, the wider mouth parts of the upper shell 4 and the lower shell 5 are fixedly connected with each other in an orientation way, the two flue connecting pipes 1 are respectively fixedly arranged on the narrower mouth parts of the upper shell 4 and the lower shell 5, and the flue connection pipe 1 communicates the insides of the upper and lower cases 4 and 5 so that the flue connection pipe 1 is coaxially rotatably inserted into the tubular through groove through the waterproof bearing 33 of the rotary connection structure 3. Still be provided with motor 32 on the fixed plate 7, the output accessible belt 31 of motor 32 drives the lower casing 5 of oil smoke separator 2 and rotates for rotating connection structure 3, thereby the oil blocking filter screen in the oil smoke separator 2 is driven by lower casing 5 and rotates with lower casing 5 jointly.

The specific structure of the oil collecting cup 70 is as shown in fig. 6, a siphon 71 is fixedly arranged in the oil collecting cup 70, a liquid suction port 73 of the siphon 71 is arranged at the bottom of a cup cavity, and a tube cavity ascends from the liquid suction port 73 as a starting point and then turns to descend until a liquid discharge port 72 of the siphon 71 penetrates through the bottom wall of the oil collecting cup 70, and the turning position 75 of the tube cavity is slightly lower than a cup opening 74 of the oil collecting cup 70. After the liquid is added into the oil collecting cup 70, as long as the water level does not exceed the turning part 75, the liquid in the cup can not be discharged from the siphon 71; once the water level exceeds the turning point 75, the static pressure of the liquid in the cup causes the liquid to flow through the turning point 75 and fill the siphon tube 71, the liquid in the descending section of the siphon tube 71 flows out of the liquid discharge port 72 due to the self-gravity and forms a negative pressure in the descending section of the siphon tube 71, the atmospheric pressure continuously presses the liquid in the oil collecting cup 70 into the ascending section of the siphon tube 71 from the liquid suction port 73, and finally the liquid in the oil collecting cup 70 is completely discharged through the liquid discharge port 72. Oil-collecting cup 70 of the oil-collecting cup 70 of course, the siphon 71 can be just placed in the oil-collecting cup 70, so the siphon 71 and the cup body do not have to be fixed.

The automatic cooking cabinet comprises the range hood 100, and further comprises an automatic cooking pot 90, an external cooking operation appliance, a controller and the like, wherein the automatic cooking pot 90 with a fixed position is arranged under the smoke collecting hood 80 of the range hood 100, the electric push rod 81 is in a contraction state in a natural state, and provides a supporting force for the smoke collecting hood 80 so that the smoke collecting hood 80 can be suspended at a position far away from the automatic cooking pot 90, so that an operation space for adding materials to the automatic cooking pot 90 for the external cooking operation appliance (such as a mechanical arm, an automatic adding and reducing mechanism or a manually operated turner and a soup ladle) is reserved; the automatic cooking pot 90 is a prior art, and comprises a pot body with an opening, a slice and a slice driving device, wherein the slice driving device is convexly arranged in the pot body, the slice is fixedly connected to the side wall of the slice driving device, the slice does not protrude out of the pot edge, and the slice driving device can rotate to drive the slice to rotate in the pot, so that the effect of stir-frying dishes is achieved. The working process of the first step is as follows: when automatic cooking pot 90 began to cook, operating personnel control electric push rod 81 pushes out downwards, electric push rod 81 drives collection petticoat pipe 80 and is close to automatic cooking pot 90, until collection petticoat pipe 80 moves to the lowest position, the pressure release space between the smoking mouth 61 of collection petticoat pipe 80 and automatic cooking pot 90 oral area is 1.5cm (the value range in pressure release space is 0 ~ 3cm, preferably 1 ~ 2cm), thereby the controller just controls electric push rod 81 to hover and makes collection petticoat pipe 80 stop, outside culinary art operation utensil can't stretch into the automatic cooking pot from the pressure release space this moment. The advantages are that: because the cooking pot is an automatic cooking pot, an operation space and a view space which are required by manual cooking are not required to be reserved between the smoke collecting hood 80 and the automatic cooking pot, the distance between the smoke collecting hood 80 and the automatic cooking pot can be greatly reduced, and therefore, the oil smoke generated by the automatic cooking pot can be more effectively sucked away; also, it is intended to ensure that the mouth of the hood 80 is not smaller than that of the automatic cooking pot to prevent the fumes generated from the automatic cooking pot from being scattered directly from the side of the hood 80 without being sucked into the hood 80. However, the above-mentioned pressure relief gap should be ensured between the smoke collecting hood 80 and the automatic cooking pot, otherwise, if the smoke collecting hood 80 is tightly covered on the automatic cooking pot, a siphon effect is easily generated, and dishes and soup in the pot are sucked into the smoke exhaust ventilator 100 together.

The working process of the second step is as follows: the operator starts the fan 50 and the motor 32, and the fan 50 causes the fume collecting hood 80 to suck the fume generated by the automatic cooking pot; the motor 32 drives the oil smoke separator 2 to rotate together with the oil blocking filter screen through the belt 31, the filter wire 21 of the oil blocking filter screen captures oil droplets in oil smoke, the oil smoke separator 2 continuously rotates, the oil droplets captured by the oil blocking filter screen are thrown onto the inner side wall of the outer wheel 22 under the action of centrifugal force, the oil smoke separator 2 keeps the rotating process and is attached to the inner side wall of the oil smoke separator 2, and therefore the oil droplets captured by the oil blocking filter screen cannot flow into the oil drainage hole 24 in the process that the oil smoke separator 2 keeps rotating. The motor 32 as a driving device is arranged outside the oil fume separator 2, so that the advantages are as follows: firstly, the driving device in the prior art is arranged on the oil dropping part 23 to drive the oil blocking filter screen to rotate relative to the oil smoke separator 2, and the driving device is arranged outside the oil smoke separator 2, so that the area of the oil dropping part 23 can be greatly reduced, and the interference effect of the oil dropping part 23 on the oil smoke gas flow is naturally weakened; secondly, the driving device can not directly contact with the oil fume, so that the driving device does not need to resist high temperature, water and oil, in other words, the driving device with the original requirements of high temperature resistance and water resistance can be replaced by the common driving device, the cost is saved, and meanwhile, the service life and the safety of the driving device are also improved.

The internal structure of the oil fume separator 2 is shown in fig. 7, the oil fume separator 2 comprises an outer wheel 22 fixedly clamped between an upper shell 4 and a lower shell 5, an oil drainage hole 24 is arranged at the central point of the lower shell 5, the oil drainage hole 24 is communicated with the flue connecting pipe 1, and an oil dripping part 23 is arranged right above the oil drainage hole 24; since the oil dropping portion 23 is slightly lower than the outer ring 22 and both end portions of the filter 21 are fixed to the outer ring 22 and the oil dropping portion 23, respectively, the filter shaft (the filter shaft is an axis on which the filter 21 is abstract) is inclined toward the oil dropping portion 23, in other words, the filter shaft has a component toward the exhaust direction of the oil smoke. The working process of the third step is as follows: the automatic cooking pot stops cooking and delivers dishes, the automatic cooking pot is positioned at the original cooking position after the dishes are delivered, an operator closes the motor 32 and the fan 50, after the oil fume separator 2 stops rotating, oil droplets attached to the inner side wall of the oil fume separator 2 before flow into the oil drainage hole 24 along the funnel-shaped lower shell 5, a small amount of oil droplets attached to the filter wires 21 flow to the oil dripping part 23 along the inclined filter wires 21 under the action of self weight, and then are converged into larger oil drops so as to drip from the oil dripping part 23 to the oil drainage hole 24; therefore, the oil droplets enter the oil drain hole 24 and then reach the oil collecting cup 70 through the flue connecting pipe 1 and the lower flue, and because the capacity of the oil collecting cup 70 is made to be larger than the oil amount in the oil fume generated by one household cooking during design, the waste oil flowing to the oil collecting cup 70 cannot rise to the liquid discharge level of the oil collecting cup 70, and the oil collecting cup 70 temporarily stores the waste oil without discharging the waste oil.

The fourth step comprises the following working processes: an operator turns on the cleaning liquid supply device, cleaning liquid (such as hot water) flows into the upper flue from the three-way pipe 60, passes through the inner part of the oil fume separator 2 and the lower flue, cleans the inner part and the lower flue, is discharged from the smoke suction port 61 of the lower flue which also serves as a liquid port to reach the oil collecting cup 70, fills the oil collecting cup 70, overflows a liquid part in the oil collecting cup 70 from the cup port 74 of the oil collecting cup 70 and flows into the automatic cooking pot right below, and discharges a part of the liquid into the automatic cooking pot from the liquid discharge port 72. After the cleaning is completed, the operator turns off the cleaning liquid supply device, no more cleaning liquid enters the oil collecting cup 70, the oil collecting cup 70 discharges all the liquid filled in the cup from the liquid discharge port 72 into the automatic cooking pot, and finally, the operator cleans the automatic cooking pot and then puts the automatic cooking pot back to the original position. Because the range hood is cleaned after cooking every time, dust cannot be fully accumulated in the lower smoke pipe, the interior of the oil fume separator 2 and the oil collecting cup 70, so that the cleaned cleaning liquid can be discharged into the automatic cooking pot and also meet the sanitary requirement, the cleaned cleaning liquid is received by the automatic cooking pot to be cleaned after cooking, and the cleaning liquid is continuously used for cleaning the automatic cooking pot, so that the cleaning liquid can be saved.

Oil collecting cup 70 the above-described oil collecting cup 70 has the siphon tube 71 as one of the liquid discharge structures and the cup mouth 74 as another liquid discharge structure, and the siphon tube 71 in the first liquid discharge structure may be replaced with other structures, for example: an oil discharge outlet is formed in the bottom wall of the oil collecting cup, and a switch valve is arranged at the oil discharge outlet. For example, the bottom wall of the oil collecting cup is provided with an oil discharge outlet which is communicated with a hose, the hose is provided with a switch valve, and the hose can convey liquid in the oil collecting cup to the automatic cooking pot, so that the automatic cooking pot is not necessarily positioned right below the oil discharge outlet when receiving clear cleaning liquid. Moreover, the oil collecting cup 70 can be used as a temporary waste liquid storage structure to receive waste liquid generated by other equipment, and the effect of conveniently cleaning the oil collecting cup 70 after the waste liquid is drained can also be achieved.

It should be noted that the three-way pipe 60 is not provided, but the smoke outlet of the upper flue is also used as the liquid inlet of the cleaning liquid; a water pump can also be arranged in the flue 6, the smoke suction port 61 of the lower flue also serves as a liquid inlet of the cleaning liquid, and the smoke exhaust port of the upper flue also serves as a liquid outlet of the cleaning liquid. It should be added that the lower flue can absorb oil smoke and can be filled with cleaning solution only in a preferable manner, and actually, the lower flue may not be provided with a liquid inlet and a liquid outlet, but provided with another liquid supply pipe for supplying cleaning solution, and the liquid supply pipe can supply cleaning solution to the oil collecting cup 70. Considering that there are other gas processing devices (such as dust removing devices) that also have the requirement of automatic cleaning, the solution of the gas channel with the liquid inlet and the liquid outlet can also be applied to other gas processing devices, provided that the gas processor (such as the dust removing component and the purifying component) for processing the gas in the gas processing device is waterproof, so that the gas processor connected in series in the gas channel can also be cleaned conveniently.
