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 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 cause further clogging of the filter screen, affecting the smoke collection effect of the hood, and greatly reducing the user experience effect

Embodiment 1

[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 state data of the range hood.

[0064] Wherein, the state data of the range hood may include the wind pressure value of the range hood, the state image of the filter screen of the range hood, or the accumulated working time of the motor of the range hood. 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 irregularly, such as the status data of the range hood is detected every time the range hood is turned on or when the range hood is turned off; or, the range hood is detected regularly The status data of the range hood, such as detecting the status data of the range hood at a fixed time every day or a fixed time every week.

[0065] Step 104, according to the state data, judge whether the filter screen o...

Embodiment 2

[0075] On the basis of the first embodiment above, this embodiment provides another method for detecting the state of the range hood. figure 2 A flow chart of the method for detecting the state of the range hood provided in this embodiment is shown, and the method describes in detail the process of determining whether the filter screen of the range hood has reached a clogged 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 , within the current cycle, record the measured wind pressure value of the range hood every set time interval.

[0077] Specifically, two pressure sensors can be installed on the range hood, wherein the first pressure sensor is used to collect the internal pressure difference (full 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 - ...

Embodiment 3

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

[0099] Step 302 , collect an image of the state of the filter screen of the range hood through the camera every set period.

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

[0101] Step 304, according to the image of the state of the filter, determine the blockage area of ​​the filter in the current cycle of the r...

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.
