Method and device for controlling temperature of steaming oven and computer equipment

The invention belongs to the field of steaming ovens, and discloses a method and device for controlling the temperature of a steaming oven and computer equipment. The method comprises the following steps: acquiring a target temperature preset by a user; determining a heating rate and a cooling rate; the heating rate is a rate at which a first preset temperature rises to the target temperature, and the cooling rate is a rate at which the target temperature drops to a second preset temperature; determining a heating duty ratio corresponding to a constant temperature control period according to the heating rate and the cooling rate; and in the current constant temperature control period, when the current temperature is not equal to the target temperature, updating the heating duty ratio according to the heating duty ratio, the current temperature and the target temperature, and performing constant temperature control according to the updated heating duty ratio. According to the invention, the temperature in the
