When the top surface of the top plate is in contact with the lower bottom surface of the blocking plate, the smoking port on the front end surface of the range fumes shell is completely exposed outside the cavity, and the outer wall of the range fumes shell is tightly sealed with the inner wall of the cavity, so that when the entire smoking part is working, the oil smoke only enters the range fumes shell from the air inlet, and then enters the smoke collecting chamber from the exhaust port at the bottom of the range fumes shell, which can effectively prevent the oil smoke from running around and achieve a better smoking effect. In addition, when the range fumes unit is fully raised, the range fumes shell completely covers the front facade of the smoke collecting chamber, blocks this plane from being contaminated by oil stains, and keeps this plane clean and hygienic after the lifting mechanism is reset.

[0055] In one embodiment, the blocking plate is horizontally arranged on the upper front facade of the smoke collecting chamber, which can play a role in blocking the oil smoke, and the blocked oil smoke can smoothly enter the air intake port on the rear side of the stove.

The excess steam can be discharged to the public flue or outdoors through the exhaust device;

[0059] 2) When the integrated stove is in standby and non-working state and the air inlet is kept closed, turn on the high-pressure water curtain or high-temperature steam to spray and clean the exhaust channel and the cavity inside the exhaust air duct from multiple directions:

[0060] 3) The air inlet opens and closes automatically, with good sealing performance to prevent water mist from overflowing during cleaning; the related lifting, flipping, and translation mechanisms are all designed with good sealing performance to separate them from the cavity to be cleaned to the greatest extent;

[0061] 4) The spraying position of high-pressure water curtain and steam can be combined with the spraying angle of water curtain, the coverage of the smoke cavity by the diffused fan-shaped area, etc., and multiple sprinkler heads can be set in different areas inside the smoke collecting cavity; steam generators or high-pressure water jet pump devices of different powers can be equipped according to different spraying methods;

[0062] 5) The frequency of cleaning can be activated according to the needs of the user, or it can be automatically activated after each use of the cooker or a cleaning reminder can be set;

[0063] 6) The waste water and residual water vapor after cleaning can be collected into the collection box or discharged to the outside through the oil recovery system of the integrated stove itself, with good recovery effect;

[0064] 7) This cleaning device can also assist in extinguishing fire and cooling the machine in the event of an accidental fire in the pot, or when the integrated stove flue fire protection function is activated;
