2. The range hood according to claim 1, wherein the gas port (7) comprises two corresponding first air deflector (15) and second air deflector (16); therefore, the air suction position can be adjusted by adjusting the first air deflector (15) or the second air deflector (16).
3. The range hood according to claim 1, wherein the air suction housing (3) comprises a track, the first air deflector (15) or the second air deflector (16) comprises a groove, and the groove and the track are matched to guide the movement direction of the first air deflector (15) or the second air deflector (16).
4. A hood as claimed in claim 2, wherein a triangular rubber block (20) is heat-sealed to the gap spacing (17), and when the guide space (18) and the outer gap (2) do not coincide, the triangular rubber block (20) is inserted into the outer gap (2) to be blocked.
5. A method of controlling an opening of a range hood, characterized in that with a range hood according to any one of claims 1 to 4,
when people use the cooking bench, only one cooking bench is opened sometimes;
opening the gap, namely opening the corresponding guide gap (18) and the external gap (2), and closing the other gap, thereby realizing the wind guiding correspondence;
avoiding inefficient circulation of air on the other side also carries away heat.
6. The range hood opening control method according to claim 5, wherein the motor is stopped immediately when the first air deflection plate (15) and the second air deflection plate (16) are together in the gap (2) that closes the outside;
when one of the first air deflector (15) and the second air deflector (16) is positioned in the gap (2) capable of closing the outside, the power of the motor is halved;
when one of the first air deflector (15) and the second air deflector (16) is positioned in the gap (2) which can open the outside, the motor is normally started.
7. The range hood opening control method according to claim 5, wherein the positions of the suction housing (3) corresponding to the two gas ports (7) comprise two temperature sensors, and the temperature sensors are in communication connection with the control part of the side cylinder (4) and the control part of the motor of the range hood; when the temperature sensor senses high temperature, the range hood is opened, and the corresponding port is opened, so that accurate and automatic control is realized.
8. A method for cleaning a range hood during closing, characterized in that with a range hood according to any of claims 1 to 4,
hot air cleaning and guide cleaning are realized;
the cover of the pot is opened, and water is placed in the pot, so that the steam sprays and cleans the air suction shell (3);
at the moment, the two side cylinders (4) continuously drive the first air deflector (15) and the second air deflector (16) to reciprocate, and the triangular rubber block (20) continuously contacts with the gap (2) between the inner wall and the outer part of the air suction shell (3); steam and inner surface greasy dirt are cleaned, and the corners of the nooks which are originally not clear are cleaned.
