Description

Oil port opening and closing method of range hood and range hood Technical Field The invention relates to the technical field of kitchen appliances, in particular to an oil port opening and closing method of a range hood and the range hood. Background With the improvement of the living standard of people, the range hood has become one of the indispensable kitchen appliances in modern home life, and can purify the kitchen environment in the cooking process, thereby improving the cooking experience. The range hood is in carrying out the in-process that the oil smoke was taken out, and the oil liquid is formed by partial condensation when the oil smoke was through the inside collection cigarette chamber of range hood, for realizing collecting and the clearance to fluid, but the range hood is provided with the pull generally and gets the oil cup of putting, but the chamber bottom of collection cigarette chamber is provided with the oil drain port, and the oil cup is installed in the oil drain port below to make the fluid of collection cigarette intracavity discharge to the oil cup in through the oil drain port. However, in the range hood provided by the prior art, in the process of taking out and cleaning the oil cup, the problem that oil in the fume collecting cavity drops to other places from the oil drain port possibly exists, so that the use experience of the range hood is affected. Disclosure of Invention The first object of the invention is to provide an oil port opening and closing method of a range hood, which can reduce the probability of oil dripping outside an oil cup and improve the use experience of the range hood. The second object of the invention is to provide a range hood, so as to reduce the probability of oil in the range hood dripping outside an oil cup and improve the use experience of the range hood. The first object is achieved by the following technical scheme: An oil port opening and closing method of a range hood, wherein the range hood comprises a machine body and two oil cups which are arranged in the machine body side by side left and right, and the machine body is provided with an oil drain port which is communicated with a fume collecting cavity corresponding to each oil cup; the oil port opening and closing method comprises the following steps: when at least one oil cup is installed in place on the machine body, the oil drain port corresponding to one oil cup installed in place is opened, and the oil drain port corresponding to the other oil cup is closed; When one oil cup is not installed in place, all oil drain ports corresponding to the oil cup are closed, and the oil drain ports corresponding to the other oil cup are opened. The oil drain port corresponding to the oil cup is closed and the other oil drain ports are opened when the oil cup is not installed in place, so that oil cannot drop downwards through the corresponding oil drain port when the oil cup is not installed in place, the risk that oil drops into the machine body or outside is avoided, the oil is difficult to clean due to oil turbulence is avoided, meanwhile, the other oil drain ports are opened, the oil in the smoke collecting cavity can flow into the other oil cup through the opened oil drain port in the cleaning process of the oil cup, smooth oil discharge is guaranteed, and furthermore, at least one oil cup is installed in place. As an alternative technical scheme of the oil port opening and closing method, when one oil cup is detected to meet a preset cleaning condition, a reminding module sends out an oil cup cleaning reminding, and when the oil cup is taken out, all oil drain ports corresponding to the oil cup are closed. As an alternative technical scheme of the oil port opening and closing method, the oil port opening and closing method comprises the steps that when one oil cup meets preset cleaning conditions and is not taken out, and the other oil cup is not installed in place, a reminding module sends out an oil cup cleaning reminding, and the oil discharge port corresponding to the oil cup is kept open, and the oil discharge port corresponding to the other oil cup is kept open. When the oil cup meets the cleaning conditions, the reminding module sends out an oil cup cleaning reminding, can remind a user to identify the oil cup to be cleaned and clean the oil cup in time so as to ensure the reliable operation of the range hood, and can avoid the problem that oil overflows due to the fact that oil liquid caused by untimely cleaning of the oil cup continues to flow into the oil cup to be cleaned by the user by closing the oil drain port corresponding to the oil cup, so that the use experience of the range hood is improved. As an optional technical scheme of the oil port opening and closing method, the oil port opening and closing method further comprises the following steps that when one oil cup is separated from a corresponding installation position, the reminding module is in first missing reminding;
