Problems solved by technology

[0002] The range hood is installed in the kitchen to discharge kitchen fumes. When consumers cook in the kitchen, a large amount of fumes will be generated. The range hood exhausts the fumes to the outside, but when the filter screen filters the fumes, some fume stains will adhere to it. After a long time, It will block the mesh of the filter, affecting the air volume and smoking effect of the range hood
The existing technology generally reminds consumers

Example Embodiment

[0061] Example one

[0062] This embodiment provides a method for detecting the state of a range hood, such as figure 1 As shown, the method includes the following steps:

[0063] Step 102: Monitor the status data of the range hood.

[0064] Among them, the status data of the range hood may include the wind pressure value of the range hood, the filter status image of the range hood, or the accumulated working time of the range hood motor. For example, the status data of the range hood can be continuously detected periodically; the status data of the range hood can also be detected from time to time, such as detecting the status data of the range hood every time the range hood is turned on or when the range hood is turned off; or, the range hood can be detected regularly The status data of the machine, such as the status data of the range hood at a fixed time every day or a fixed time every week.

[0065] Step 104: Determine whether the filter screen of the range hood has reached a bl...

Example Embodiment

[0074] Example two

[0075] On the basis of the first embodiment, this embodiment provides another method for detecting the state of the range hood. figure 2 The flow chart of the method for detecting the state of the range hood provided by this embodiment is shown. The method describes in detail the process of determining whether the filter screen of the range hood reaches a blocked state by detecting the change of the wind pressure value of the range hood. Such as figure 2 As shown, the method includes the following steps:

[0076] Step 202: In the current cycle, record the actual measured wind pressure value of the range hood once every set interval.

[0077] Specifically, two pressure sensors can be installed on the range hood, where the first pressure sensor is used to collect the internal pressure difference (total pressure-static pressure) of the range hood, and the second pressure sensor is used to collect the external pressure difference of the range hood. (Total pressure...

Example Embodiment

[0097] Example three

[0098] On the basis of the first embodiment above, this embodiment provides a method for judging whether the filter of the range hood is blocked by using the camera to collect the blocked area of ​​the filter. Such as image 3 As shown, the method includes the following steps:

[0099] Step 302: Collect an image of the filter screen of the range hood through the camera every interval setting period.

[0100] A camera is installed on the range hood to set the image collection period, and the camera is used to collect the filter status image of the range hood according to the set period. For example, one filter status image can be collected within a set period, or multiple images can be collected according to the average interval time within a set period to obtain multiple filter status images.

[0101] Step 304: Determine the filter blockage area of ​​the range hood in the current cycle according to the filter status image.

[0102] Perform image recognition on t...

Abstract

The invention provides a range hood state detection method, device and system and a range hood, and belongs to the technical field of smart homes. The method comprises the following steps of monitoring state data of the range hood; judging whether a filter screen of the range hood reaches a blocked state or not; and if yes, sending a filter screen blockage message according to the state data. According to the range hood state detection method, device and system and the range hood, through monitoring the state data of the range hood, judging whether the filter screen of the range hood reaches the blocked state or not and sending the filter screen blockage message to prompt a user or a server if the filter screen reaches the filter screen blocked state, the range hood can be cleaned in time,and the use experience of the user is improved.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to a method, device, system and range hood state detection method for a range hood. Background technique [0002] The range hood is installed in the kitchen to discharge kitchen fumes. When consumers cook in the kitchen, a large amount of fumes will be generated. The range hood exhausts the fumes to the outside, but when the filter screen filters the fumes, some fume stains will adhere to it. After a long time, It will block the mesh of the filter screen, affecting the air volume and smoking effect of the range hood. The existing technology generally reminds consumers to clean the filter screen regularly, but consumers in different regions have different cooking habits, and the accumulation of time cannot accurately feedback the clogging of the filter screen of the hood. At the same time, when the filter screen is clogged, some consumers may not want to clean it. Cleaning will c...
