4) judging whether T is greater than or equal to a second preset value b, wherein the second preset value b is greater than the first preset value a, if yes, operating a cooling circuit to cool the motor (43), and then entering the step 5); if not, running a conventional line, and then entering the step 5);
5) operating a linkage flow of the range hood and the steam box, discharging steam of the steam box by the range hood, and returning to the step 2);
6) detecting the current real-time temperature T of a motor (43) of the range hood, and judging whether the T is less than or equal to a first preset value a; if yes, the steam box is started, a preheating circuit is operated, the motor (43) is preheated, and then the step 8) is carried out; if not, entering step 7);
7) judging whether T is greater than or equal to a second preset value b, if so, operating a cooling line to cool the motor (43), and then entering step 8); if not, returning to the step 2);
8) detecting whether the range hood is closed or not, entering a delayed closing state, if so, closing the steam box, completely opening a one-way valve (32) between the steam box and the range hood, and discharging steam from the second box body (3) into the first box body (2); if not, returning to the step 2);
in the steps 3) and 6), the preheating line is that steam generated after water in the water tank (6) is introduced into the steam generator (5) passes through the motor (43) through the second pipeline (432), preheats the motor (43), and then the steam returns to the steam generator (5) and is introduced into the second box body (3); in the steps 4) and 7), the cooling line is that water in the water tank (6) passes through the motor (43) through the first pipeline (431) and absorbs heat of the motor (43), then the water is introduced into the steam generator (5), and generated steam is introduced into the second box body (3); in the step 4), the conventional circuit is that the water in the water tank (6) passes through the steam generator (5) to generate steam and then the steam is introduced into the second box body (3).
9. The control method according to claim 8, characterized in that: in step 5), the linkage process of the range hood and the steam box comprises the following steps:
5.1) the steam box starts to work normally;
5.2) detecting whether a door body of the steam box is opened, if so, entering the step 5.3), and if not, entering the step 5.5);
5.3) detecting whether a fan (4) of the range hood is in the highest gear of the working state, if so, controlling a one-way valve (32) between the range hood and the steam box to be completely opened for a certain time, and then closing the one-way valve (32); if not, go to step 5.4);
5.4) controlling a one-way valve (32) between the range hood and the steam box to be completely opened for a certain time, simultaneously adjusting a fan (4) of the range hood to the highest gear to run for a certain time, and then, recovering the original state of the range hood, and closing the one-way valve (32);
5.5) detecting whether the range hood is started, if so, entering a step 5.6), and if not, entering a step 5.7);
5.6) detecting whether a fan (4) of the range hood is in the highest gear of the working state, if so, controlling the opening degree of a one-way valve (32) between the range hood and the steam box to be X, and then returning to the step 5.2); if not, controlling the opening degree of the opening of the one-way valve (32) between the range hood and the steam box to be Y, satisfying that X is more than Y and less than 1, and then returning to the step 5.2);
5.7) the fan (4) of the range hood operates in a state of less than the minimum working state gear, controls the one-way valve (32) between the range hood and the steam box to be completely opened, and then returns to the step 5.2).
