AI Technical Summary

Problems solved by technology

The smoke removal equipment is already a kitchen equipment that is widely used in households, but there are still some functions that need to be improved. For example, the adjustment of the air volume of the smoke removal equipment needs to be manually set by the user, but the smoke removal equipment has a lot of oil stains, which is not hygienic and inconvenient to operate; The linkage of the stove needs the close cooperation of the stove, etc.
Moreover, the past smoke removal equipment was only used to extract oil fumes, and did not fully utilize its capabilities

Embodiment 1

[0039] An intelligent smoke removal device, comprising an image acquisition unit, an information processing unit, and a main control unit; the image acquisition unit is connected to the information processing unit, and the information processing unit is connected to the main control unit; the image acquisition unit collects image information of a cooktop, and the information processing unit According to the analysis and processing of the collected cooktop image information, the user's cooking intention is judged, and then the main control unit controls other devices of the smoke removal device according to the user's cooking intention. In this embodiment, the user controls when the image acquisition unit is turned on, or keeps it turned on all the time.

[0040] Preferably, the smoke removal device further includes a living body detection unit, which is connected to the information processing unit, and the living body detection unit is used to detect whether a user is approachi...

Embodiment 2

[0046] This embodiment provides a control method for intelligent smoke removal equipment, which can be applied to the intelligent smoke removal equipment described in Embodiment 1, but is not limited thereto. This method uses computer vision algorithms to detect the amount of smoke on the stove size, and automatically adjust the speed of the fan according to the amount of smoke, specifically through the following steps:

[0047] S1, using a camera to collect images above the stove;

[0048] S2, using a computer vision algorithm to detect the amount of smoke;

[0049] S3, adjusting the rotational speed of the range hood blower according to the amount of smoke.

[0050] The first solution, step S2 includes:

[0051] S21, acquiring a moving foreground in the image;

[0052] Preferably, the foreground detection algorithm may be a background modeling algorithm such as GMM, ViBe, CodeBook, etc.; it may be a frame difference algorithm such as two-frame difference, three-frame diff...

Embodiment 3

[0098] The intelligent smoke removal equipment control method provided in this embodiment can be applied to the intelligent smoke removal equipment in the first embodiment, and can also be improved on the basis of the second embodiment, but it is not limited thereto. This method monitors the state of the cooker switch, and realizes the smoke cooker linkage according to the amount of smoke, specifically through the following steps:

[0099] S1, using a camera to collect images above the stove;

[0100] S2, using a computer vision algorithm to detect the position and state of the stove switch;

[0101] S3, if the cooktop turns from off to on, then turn on the smoke detection;

[0102] S4, decide whether to open the smoke removal device according to the smoke detection result;

[0103] S5, if the stove turns from on to off, and the amount of smoke gradually disappears, the range hood blower operates at a low speed to switch air and then shuts down.

[0104] The first algorithm...

Abstract

The invention discloses an intelligent smoke removing device which comprises an image collecting unit, an information processing unit and a main control unit. The image acquisition unit is connected with the information processing unit, and the information processing unit is connected with the main control unit; the image collecting unit collects cooking bench image information, the information processing unit analyzes and processes the collected cooking bench image information and judges the cooking intention of a user, and then the main control unit controls the smoke removing device according to the cooking intention of the user. The invention further discloses a control method capable of being applied to the intelligent smoke removal equipment. The method can intelligently identify theon-off state of the cooking bench to realize smoke stove linkage; the intelligent control system intelligently identifies the smoke volume to automatically control the rotating speed of a fan of thesmoke removing equipment, intelligently identifies food materials to provide corresponding intelligent interactive experience such as a menu, a cooking method, gesture control, voice control and display touch control, and enables the smoke removing equipment to be used more intelligently.

Description

technical field [0001] The invention relates to the field of intelligent kitchen equipment, in particular to an intelligent smoke removal equipment and a control method thereof. Background technique [0002] Smoke removal equipment is a kitchen appliance that purifies the kitchen environment. It is installed on the top of the kitchen stove, which can quickly take away the waste burned by the stove and the oil fume harmful to the human body produced during the cooking process, and discharge it to the outside, reduce pollution, purify the air, and have the safety guarantee function of detoxification and explosion protection. The smoke removal equipment is already a kitchen equipment that is widely used in households, but there are still some functions that need to be improved. For example, the adjustment of the air volume of the smoke removal equipment needs to be manually set by the user, but the smoke removal equipment has a lot of oil stains, which is not hygienic and incon...
