[0018] The utility model will be further described below in combination with the drawings and embodiments.

[0019] Referring to Figs. 1-2 The linkage device of the electric appliance comprises a primary device 1, a secondary device 2 and a current monitor 3 for detecting the load or current of the primary device 1, the current monitor 3 is electrically connected with the primary device 1 and the secondary device 2 respectively, and the current monitor 3 is used for interlocking the start and stop of the secondary device 2 according to the detected load or current.

[0020] The current monitor 3 is connected in series in the live wire L or the neutral wire N of the primary device 1.

[0021] Further comprising a primary circuit and a secondary circuit, the primary device 1 is arranged on the primary circuit, the secondary device 2 is arranged on the secondary circuit, and the primary circuit and the secondary circuit are prior art, which will not be described in detail here.

[0022] The current monitor 3 is provided with a monitoring circuit for detecting the current size of the primary device, and the current monitor 3 is also provided with an automatic on-off circuit of the secondary device, when the current monitor 3 detects that the load or current consumption exceeds the threshold value, the action is triggered, and then the secondary device 2 is started.

[0023] The alternating current range of the load detected by the current monitor 3 is 0.5A-50A, and under the premise that the maximum current and power rating are not exceeded, the current monitor 3 can monitor one or more devices at the same time.

[0024] The load of the primary device 1 can be an inductive load or a resistive load, and the current monitor 3 is suitable for the working condition that the primary device 1 is an inductive load or a resistive load.

[0025] The load current of the secondary device 2 is ≤6A, and when it is detected that the load of the primary device 1 exceeds the preset starting point, the current monitor 3 will automatically turn on the independent control circuit or the secondary device 2 with a maximum of 6A.

[0026] The primary device 1 is an induction cooker or an electric ceramic stove, and the secondary device 2 is an exhaust hood; the exhaust hood is interlocked with the induction cooker or the electric ceramic stove to start and stop: the current monitor 3 is connected to the live line or the neutral line loop of the induction cooker or the electric ceramic stove, and when it is detected that the induction cooker or the electric ceramic stove starts and stops, the current monitor 3 can automatically start and stop the exhaust hood.

[0027] Alternatively, the primary device 1 is a bathroom electric water heater or a clothes dryer, and the secondary device 2 is an exhaust fan; the current monitor 3 is connected to the live line or the neutral line loop of the bathroom electric water heater or the clothes dryer, and when it is detected that the bathroom electric water heater or the clothes dryer starts, the current monitor 3 can start the exhaust fan, so the current monitor 3 and the switch 4 control the start and stop of the same exhaust fan respectively; the logic of the exhaust fan double control system is as follows:

[0028] 1. Startup authority (when the exhaust fan is off):

[0029] Both the current monitor 3 and the switch 4 have independent startup authority;

[0030] 2. Control logic in operation (when the exhaust fan is on):

[0031] Device operation priority: when the water heater / dryer is working, the switch 4 is shielded from closing function;

[0032] Manual control right: after the water heater / dryer stops, the switch 4 resumes the closing control right;

[0033] Automatic control rule:

[0034] Switch 4 remains on → current monitor 3 does not interfere with the operation of the exhaust fan;

[0035] Switch 4 is off → current monitor 3 automatically closes the exhaust fan after the water heater / dryer stops.

[0036] In actual application scenarios, people enter and exit the bathroom to manually control the exhaust fan with the switch 4; the current monitor 3 automatically controls the exhaust fan according to the working state of the water heater or the clothes dryer; when the current monitor 3 is applied to the bathroom electric water heater, it has a delay closing function, and the current monitor 3 will maintain the continuous operation of the exhaust fan for 15 minutes after detecting that the bathroom electric water heater stops, in order to actively eliminate the accumulation of moisture.
