[0031] The technical solutions and other beneficial effects of the application will be apparent from the following detailed description of the specific embodiments of the application, combined with the accompanying drawings.

[0032] In addition, the terms "first", "second", "third", etc. are used only for descriptive purposes and are not to be construed as indicating or implying relative importance or a specific order of limiting the features indicated by these terms, and thus the features with "first", "second", "third", etc. can explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly and specifically limited.

[0033] Please refer to Figure 1 The embodiments of the present application provide a kitchen appliance linkage control system, which comprises a kitchen air conditioner 10 and an intelligent stove 20. The kitchen air conditioner 10 comprises a detection module 11, a first controller 12 and a first wireless communication module 13. The detection module 11 and the first wireless communication module 13 are connected with the first controller 12.

[0034] In specific implementation, the detection module 11 is used for detecting the kitchen smoke concentration and outputting a corresponding electrical signal according to the kitchen smoke concentration, and outputting an abnormal detection signal when the voltage value corresponding to the electrical signal is greater than a preset voltage; the first controller 12 is used for outputting an abnormal control signal according to the abnormal detection signal; and the first wireless communication module 13 is used for sending the abnormal control signal to the intelligent stove 20, so that the intelligent stove 20 disconnects the gas passage according to the abnormal control signal.

[0035] After the kitchen air conditioner 10 is started, the detection module 11 detects the kitchen smoke concentration. When the kitchen smoke concentration is greater than a certain value, an abnormal detection signal such as a low-level signal is outputted, indicating that there is a certain safety hazard in the kitchen at this time. Conversely, if the kitchen smoke concentration does not exceed a certain value, a smoke detection signal such as a high-level signal is outputted.

[0036] When the detection module 11 outputs the smoke detection signal, the first controller 12 outputs a corresponding detection control signal according to the smoke detection signal, and sends the detection control signal to the intelligent stove 20 through the first wireless communication module 13. The intelligent stove 20 turns on the gas passage according to the detection control signal.

[0037] When the detection module 11 outputs the abnormal detection signal, the first controller 12 outputs a corresponding abnormal control signal according to the abnormal detection signal, and sends the abnormal control signal to the intelligent stove 20 through the first wireless communication module 13. The intelligent stove 20 disconnects the gas passage according to the abnormal control signal. Thus, automatic monitoring of the intelligent stove 20 is realized, and the kitchen safety is improved.

[0043] The voltage value of the adjustable resistor RT is used as the preset voltage of the comparator U1, when the voltage value of the electric signal is greater than the preset voltage, the comparator U1 outputs the low level signal, and the first controller 12 obtains the low level signal through the connection port connection interface CN2; when the voltage value of the electric signal is not greater than the preset voltage, the comparator U1 outputs the high level signal, and the first controller 12 obtains the high level signal through the connection port connection interface CN2.
