Problems solved by technology

[0003] With the advent of the smart home era, people's requirements for household appliances are more diverse and more intelligent, and the kitchen is an indispensable living environment in daily life, but the traditional range hood can only save users from kitchen fumes However, the intelligence of the range hood in the prior art is mainly reflected in the function of the range hood itself, or simply adding Internet functions, without intelligently controlling the operation of the range hood according to user information characteristics or needs, and not Really realize the real-time interaction between the user and the range hood
[0004] For example, a Chinese patent discloses a smart screen range hood, which includes a range hood body and a smart screen installed on the range hood body, and also includes a controller, a communication module, and an audio output module, wherein the smart screen, the communication module and the audio output module are connected to the controller, and an intelligent networked smart screen is added to the range hood, which is equipped with Internet functions to provide users with diversified service functions, but it does not provide users with intelligent services based on their own characteristics.

Embodiment 1

[0049] Such as figure 2 As shown, in this embodiment, the face image of the target user is detected to obtain the user feature information of the target user, so that the operating speed of the range hood matches the user feature information, and the range hood is controlled to run at a corresponding speed. The operating speed of the range hood matches the user's characteristic information. According to the target user's gender information, age range, and emotional characteristics in the current state, the target operating speed of the range hood is determined, and the information interaction between the target user and the range hood is realized, so that the range hood Smarter and more humane.

[0050] In this embodiment, the operating speed of the range hood is controlled by the fan motor, and the fan motor speed is divided into three levels: soft speed, medium speed, and high speed. Speed, medium speed, and high speed run at levels that match the user's characteristic inf...

Embodiment 2

[0057] Such as image 3 As shown, the difference between this embodiment and the first embodiment above is that gender information, age information and emotional feature information are used as indicators for determining the target operating mode of the range hood, and each indicator is divided into different levels, and the ABC classification weight method is used to determine each indicator. The index assigns weight and grade proportion, and determines the final evaluation result E, which is used to prompt the target user whether the range hood executes the corresponding speed.

[0058] Such as image 3 As shown, in this embodiment, E=W*w i +X*x j +Y*y k , where the weights of gender information, age information and emotional feature information are W, X, Y respectively, and W+X+Y=1; w i Represents the proportion of index grades corresponding to gender information, x j Represents the proportion of index levels corresponding to age information, y k Represents the propor...

Embodiment 3

[0063] Such as Figure 4 As shown, the difference between this embodiment and the first embodiment above is that: Figure 4 As shown, in this embodiment, the first song collection corresponding to the gender information is determined based on the gender information of the target user; the second song corresponding to the age information is determined from the first song collection based on the age information of the target user A collection: determining a target song collection corresponding to the emotional characteristic information from the second song collection based on the emotional characteristic information of the target user, wherein the target song collection includes multiple songs.

[0064] Such as Figure 4 As shown, in this embodiment, based on the user characteristic information, the target user is prompted whether to automatically play the song, and the voice information of the target user is detected; if the detection result is yes, then the songs of the targ...

Abstract

The invention discloses a control method of a range hood. The control method comprises the following steps of: detecting a face image and voice information of a target user in a target area where therange hood is located; acquiring user characteristic information of the target user, wherein the user characteristic information comprises gender information, age information and emotion characteristic information; determining a target operation mode of the range hood based on the user characteristic information; and controlling the range hood to operate in the target operation mode. According tothe control method of the range hood, the operation mode of the range hood is controlled to be matched with the user characteristic information of the target user, so that the functions of the range hood are diversified, the interaction between the user and the range hood is realized, the user obtains diversified pleasant cooking experience, and the smoke exhaust efficiency of the range hood can be improved. The invention further discloses a control device applying the control method of the range hood.

Description

technical field [0001] The invention belongs to the technical field of kitchen appliances, and in particular relates to a control method and a control device for a range hood. Background technique [0002] Cooking is a processing process that uses complex and regular means to convert ingredients into food, making food more delicious, better looking, and better smelling, and food brings people physical and spiritual pleasure. In the cooking process of traditional Chinese meals, frying, frying, cooking, and deep-frying account for a large proportion, and a large amount of oily fumes are also generated, which not only pollutes the kitchen environment, but also affects people's health and mood.
