Abstract

The invention discloses a control method, device and system of an oven fan and an oven, wherein the method comprises the following steps of detecting an internal temperature of the oven; under the condition that heating equipment of the oven is in a heating state, increasing the rotational speed of the fan of the oven according to the internal temperature of the oven; and under the condition thatthe heating equipment of the oven is in a state of stopping heating, reducing the rotational speed of the fan of the oven according to the internal temperature of the oven. The control method, deviceand system of the oven fan and the oven solve the technical problem that as the opening period of a relay of the oven is longer, the fluctuation of the internal temperature of the oven in one period is lager, and the internal temperature of the oven cannot be accurately controlled in the prior art.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to a control method, device, system and oven for an oven fan. Background technique [0002] At present, most electric ovens usually use a relay to control the start and stop of the heating device, so as to heat the food. The basic control principle of such an oven is: the internal temperature of the oven is detected by the temperature sensing device, and the collected temperature signal is transmitted to the single-chip microcomputer. In the working state, the internal temperature of the oven is controlled within a certain range by means of intermittent heating. [0003] However, since the switching frequency of the relay itself is low, and the working life is limited by the number of switching times, the switching cycle of the relay is relatively long in practical applications. In a working cycle, when the relay is closed, the heating device starts to work, and the temperatur...
