The prompt information can be of various types, such as voice prompt, text prompt, light prompt and the like.

Optionally, the prompting module can be various. For example, the prompt module can set up on the shell of lampblack absorber or lampblack absorber surface for show tip information, this tip information is corresponding with the dirty degree of filter screen, and when judging that the filter screen needs to wash or change, tip information is used for the suggestion filter screen and needs to wash or change. For example, the prompt module may further include a display interface of a remote controller or a line controller, and is configured to display a prompt message, where the prompt message corresponds to a degree of soiling of the filter screen, and when it is determined that the filter screen needs to be cleaned or replaced, the prompt message is used to prompt that the filter screen needs to be cleaned or replaced. For another example, the prompt module may further include a voice prompt module for playing voice prompt information, the dirty degree of the filter screen of the voice prompt information corresponds to the dirty degree of the filter screen, and when the filter screen needs to be cleaned or replaced, the voice prompt information is used for prompting that the filter screen needs to be cleaned or replaced. Certainly, the prompting module is not limited to the above, and those skilled in the art may selectively set the prompting module according to actual conditions, for example, a buzzer alarm prompting mode may be adopted.

Optionally, the microprocessor is used for identifying the image of the filter screen, and the mode of analyzing and judging the dirt degree of the filter screen can be various. For example, the image data of the initial filter screen may be preset, the collected current filter screen image data may be compared with the pre-stored initial filter screen image data, and whether the filter screen image data exceeds the set range may be determined according to the comparison result. Or, the initial image state data is not set, a preset threshold value of the image state data is directly set, the detected image data parameter of the current filter screen is compared with a preset threshold value range, and the preset threshold value range can be set according to the data parameter change of the range hood in the normal operation state when the filter screen is in the clean state. For the comparison mode of the filter screen image data, a pixel point information comparison mode, an area comparison mode and the like can be adopted.

For example, the camera may be used to collect the information of the state image of the filter screen of the range hood according to a set period, where the set period may be determined by a user or a manufacturer according to the usage of the filter screen, for example, the state image of the filter screen is shot every five days or every ten days, and the user may also freely control the camera to perform the detection of the filter screen at any time. After the acquired filter screen image information is transmitted to the microprocessor, the microprocessor can be used for identifying the image information, for example, pixel point information comparison can be carried out on a current image and a pre-stored initial image, the numerical difference value of each pixel point in the image to be identified and the pixel point at the corresponding position of the pre-stored initial image is judged, if the numerical difference value exceeds a set range or a preset threshold value, the corresponding pixel point is determined to be a dirty point, and under the condition that the number of the dirty points accounts for the number of the total pixel points and exceeds the set range or the preset threshold value, the filter screen can be determined to be required to be cleaned or replaced; further, when judging that the filter screen needs to be cleaned or replaced, the prompting module can be utilized to prompt a user that the filter screen needs to be cleaned or replaced.
