A control method and device of a kitchen air conditioner and the kitchen air conditioner
By installing an oil stain detection light emitting unit and a receiving unit inside the kitchen air conditioner, and combining the oil fume concentration and detection signal parameters, the oil stain level can be accurately determined and the cleaning agent spray can be controlled. This solves the problem of difficult-to-remove oil stains on the surface of the kitchen air conditioner heat exchanger, and achieves efficient and economical oil stain cleaning.

Abstract
This invention provides a control method, device, and air conditioner for a kitchen air conditioner. The control method includes: acquiring the concentration of cooking fumes in the kitchen and the cumulative duration for which the concentration meets a first preset condition; if the cumulative duration is greater than the first duration, acquiring a second oil stain detection signal; determining the oil stain level on the surface of a kitchen heat exchanger based on the signal strength value, the signal reflection angle value, and the cumulative duration of the second oil stain detection signal; and determining the spray pressure and spray duration of an oil stain cleaner based on the oil stain level; wherein the first preset condition is that the cooking fume concentration is greater than or equal to a cooking fume concentration threshold. This invention solves the problems of incomplete cleaning of oil stains on the surface of kitchen heat exchangers or waste caused by excessive spraying of oil stain cleaner.
