1. A control method for a kitchen air conditioner in a kitchen equipped with a range hood, the kitchen air conditioner comprising:
a housing, in which an electric control board is disposed wherein a return air inlet, is provided on the housing, and comprises a first return air inlet and a second return air inlet; the first return air inlet is used for the air that enters the kitchen, and the second return air inlet leads to the outside of the kitchen through an air duct and is used for introducing the outdoor air; wherein a first air valve is disposed in the first return air inlet and is electrically connected to the electric control board; a second air valve is disposed in the second return air inlet and is electrically connected to the electric control board; a temperature measurement device for measuring the temperature at the second return air inlet is disposed on a sidewall of the second return air inlet, and is electrically connected to the electric control board; and
the temperature measurement device is a temperature probe; and
the air conditioner comprises a current detection device disposed outside the housing and electrically connected to the electric control board, wherein the current detection device is used for detecting a current of the range hood and determining whether the range hood works, and wherein the current detection device is an annular current transformer sleeved on a power line of the range hood,
wherein the control method comprises:
when the air conditioner stands by, controlling, by the electric control board, the first air valve and the second air valve to close;
acquiring, by the electric control board, a current of the power line of the range hood that is induced by the annular current transformer in a set time;
determining, by the electric control board according to the current of the power line induced by the annular current transformer, whether the range hood works by determining whether the current induced by the annular current transformer in the set time is less than a set value and determining that the range hood does not work in response to the current being less than the set value; and
controlling, by the electric control board according to whether the range hood works, a working status of the air conditioner, wherein the controlling comprises, controlling, by the electric control board, the first air valve to open in response to the range hood not working, so that the first return air inlet returns air; and controlling a motor of the air conditioner to work and a compressor of the air conditioner to implement refrigeration after a preset time.
