For the understanding of those skilled in the art, the following description of the embodiments of the present invention with reference to the drawings is not intended to limit the scope of the embodiments of the present invention.
The embodiment of the invention provides a control method for dehumidifying and sterilizing a steam box, which comprises the following steps of S101-S102:
s101, detecting the environment of the inner container of the steam box.
In the embodiment of the invention, in order to determine whether the environment of the inner container of the steam box is mildewed or possibly mildewed, the environmental data of the inner container of the steam box can be detected in real time, so that the environmental condition of the inner container of the steam box can be judged according to the current environmental data, the inner container is prevented from smelling and mildewing, and the mildewed inner container is cleaned in time.
In embodiments of the present invention, the detection of environmental data may include one or more of, for example, including but not limited to: temperature detection, humidity detection, odor detection, wind speed detection, concentration detection, residue detection, and the like. Different detection devices and methods can be set according to different detection objects, and specific devices and specific implementation methods are not limited.
Optionally, the detecting the environment of the inner container of the steam box may include: detecting the humidity and the peculiar smell of the inner container environment of the steam box; accordingly, the detected environmental data may include: a humidity detection value and an odor detection value.
In the embodiment of the invention, if the inner container of the steam box is humid, the mold and the fungus are easy to breed, and the inner container becomes moldy and generates peculiar smell, so that whether the mold and the fungus are bred in the inner container of the steam box can be determined only by detecting the humidity and the peculiar smell of the inner container environment of the steam box. The embodiment of the invention detects the environmental humidity of the inner container of the steam box, can determine whether the environment of the inner container of the steam box has the condition of breeding the mould and the fungus, can detect the peculiar smell of the environment of the inner container of the steam box, and can directly determine whether the inner container of the steam box has the mould or the fungus.
Optionally, the method further comprises:
when the cooking work of the steam box is detected to be finished, starting timing of a timer of the steam box; when the timing duration of the timer reaches a preset time threshold, detecting the environment of the inner container of the steam box; and the number of the first and second groups,
in the timing process of the timer, when the cooking function of the steam box is started, the timer is cleared.
In the embodiment of the present invention, in order not to affect the normal cooking function of the steam box, the step of detecting the environment of the inner container of the steam box needs to be performed after the completion of the cooking operation of the steam box is detected. In addition, in order to achieve the purpose of cleaning the inner container of the steam box in time, the timer of the steam box can be started to time when the cooking work of the steam box is detected to be finished, and the environment of the inner container of the steam box is detected when the timing duration of the timer reaches a preset time threshold. After the humidity of the inner container of the steam box is continuously kept higher than the humidity reference value for a certain time, the possibility of humidity and mildew in the steam box is judged, and the machine automatically enters the dehumidification program control; or after the peculiar smell of the inner container is continuously kept higher than the peculiar smell reference value for a certain time, judging that the possibility of mildewing exists in the steam box, and automatically entering the control of a sterilization and cleaning program.

And in the second situation, when the main control unit 1 compares that the humidity detection value is greater than or equal to the humidity reference value and the peculiar smell detection value is smaller than the peculiar smell reference value, the main control unit 1 judges that the inner container environment of the steam box is moist but has no peculiar smell, but the inner container can cause a moldy and smelly trend in the moist environment for a long time, so that the main control unit 1 judges that the steam box dehumidification function needs to be started.
And thirdly, when the main control unit 1 compares that the humidity detection value is smaller than the humidity reference value and the peculiar smell detection value is larger than or equal to the peculiar smell reference value, the main control unit 1 judges that the environment of the inner container of the steam box is dry but has peculiar smell, food residues or mould residues possibly exist in the inner container, and therefore the main control unit 1 judges that the steam box sterilization function needs to be started.
And fourthly, when the main control unit 1 compares the humidity detection value with the humidity reference value or more and the peculiar smell detection value with the peculiar smell reference value or more, the main control unit 1 judges that the inner container of the steam box is humid and has peculiar smell, food residues or mould residues possibly exist in the inner container, and the inner container is not subjected to sufficient ventilation and drying, so that the main control unit 1 judges that the dehumidification and sterilization functions of the steam box need to be started.
According to the embodiment of the invention, the detected humidity value is compared with the humidity reference value, the detected peculiar smell value is compared with the peculiar smell reference value, and corresponding dehumidification and/or sterilization operations are carried out according to different comparison results, so that the steam box can carry out corresponding treatment in time according to the change of the environmental data of the liner, and the steam box can continuously keep the liner clean and sanitary in a long-time idle stage.
