Problems solved by technology

[0002] With the widespread use of household appliances, while household appliances bring us convenience, due to their own structural defects and improper operation by users, there are great potential safety hazards in the use of household appliances.
For example, due to the unreasonable design of the internal circuit of the home appliance, the circuit is short-circuited and the home appliance burns and catches fire, or the user forgets to turn off the home appliance after using the home appliance. The home appliance is in the working state for a long time and the electrical components are damaged, which causes the home appliance to catch fire.

Embodiment 1

[0090] Such as image 3 As shown, according to the above-mentioned embodiments of the present invention, preferably, the execution unit specifically includes: a data supplementation unit 310, configured to send the first detection value to the preset database when the oil fume state is normal, and determine and detect the time again Corresponding preset oil fume content value.

[0091] In this embodiment, by sending the first detection value in the normal state to the database, and calculating the average value of the first detection value and the preset oil smoke content value corresponding to the detection time, the detected preset oil smoke content The more value data, the more accurate the preset soot content in the database, thereby reducing the error between the preset soot content value and the actual soot content value, and improving the detection accuracy.

[0092] Preferably, since the amount of cooking fume generated by household appliances is not an accurate data,...

Embodiment 2

[0095] Such as image 3 As shown, according to the above-mentioned embodiments of the present invention, preferably, the execution unit further includes: an alarm unit 312, configured to send the first detection value to the server when the oil fume state is an abnormal state, and the server sends the first detection value to the abnormal state The corresponding first abnormal signal is sent to the message device to send an alarm after receiving the first abnormal signal; the prompt unit 314 is used to send the second abnormal signal corresponding to the abnormal state of the first detection value to the The preset mobile device, after receiving the second abnormal signal, the preset mobile device displays a prompt message corresponding to the second abnormal signal; the safety unit 316 is used to set the first detected value to correspond to the abnormal state when the cooking fume state is abnormal. The third abnormal signal is sent to the controller, and the controller contro...

Embodiment 3

[0101] Such as image 3 As shown, according to the above-mentioned embodiment of the present invention, preferably, the execution unit further includes: a re-detection unit 318, configured to determine the operation duration after the preset operation is performed, and detect the oil fume in the air again after the operation duration is longer than the preset duration , to obtain the second detection value, if the determination unit determines that the second detection value is still in an abnormal state, send a fourth abnormal signal corresponding to the abnormal state of the second detection value to the preset target.

[0102] In this embodiment, after the operating time is longer than the preset time, in order to avoid the problem of powering off the home appliance because the user does not hear the alarm sound of the message device, or the user does not carry a mobile device, or the home appliance is already in a burning state. Problem, at this time, detect the oil fume i...

Abstract

The invention provides a detection method and a detection device. The detection method is used for household appliances and comprises steps as follows: detecting cooking fume in the air and analyzing the cooking fume to acquire a first detection value; determining the detection moment when the first detection value is acquired and inquiring a preset cooking fume content value at the detection moment in a preset database; comparing the first detection value with the preset cooking fume content value at the detection moment to acquire a comparison result; determining the state of the cooking fume at the detection moment according to the comparison result; performing preset operation according to the state of the cooking fume. According to the technical scheme, the preset cooking fume content value is compared with the first detection value of the cooking fume in the air at the corresponding moment, so that whether the state of the cooking fume of the household appliances in different work states in the air is normal or not is detected, the preset cooking fume content value in the preset database is updated, the effect of accurately detecting the content of the cooking fume in the air is realized, influences of environment on the detection result are reduced, and the safety of the household appliances in the use process is improved.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a detection method and a detection device. Background technique [0002] With the widespread use of household appliances, while household appliances bring us convenience, due to their own structural defects and improper operation by users, there are great potential safety hazards in the use of household appliances. For example, due to the unreasonable design of the internal circuit of the home appliance, the circuit is short-circuited and the home appliance burns and catches fire, or the user forgets to turn off the home appliance after using the home appliance. [0003] Therefore, how to improve the work safety of household appliances has become a technical problem to be solved urgently. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0005] To this end, an object of the p...
