For example, when the temperature sensor 22 detects that the temperature in the water tank 10 is too high, the monitoring terminal 21 may control the water distributor 30 to stop inputting hot water, or may control the water distributor 30 to input cold water for adjustment, and when the temperature sensor 22 detects that the temperature in the water tank 10 is too low, the monitoring terminal 21 may control the water distributor 30 to stop inputting cold water, or may control the water distributor 30 to input hot water for adjustment, thereby achieving temperature adjustment.
The liquid level sensor 23 can be disposed below the interior of the water tank 10, and when the liquid level sensor 23 detects that the water level in the water tank 10 is too low, the monitoring terminal 21 can control the water distributor 30 to feed water, so as to avoid the phenomenon that the water level in the water tank 10 is too low.
In order to improve the accuracy of temperature detection, the temperature sensor 22 is a temperature measuring cable, and the temperature measuring cable 24 extends along the height direction of the water tank 10 to ensure that temperature detection can be realized at each position inside the water tank 10; it should be noted that the temperature measuring cable 24 at this time is composed of the temperature sensors 22, the wires, the tensile steel wire ropes and the sheaths, that is, the plurality of temperature sensors 22 are arranged on one wire at intervals, the rigidity of the wire is improved by the tensile steel wire ropes so as to ensure that the wire can be vertically arranged along the height of the water tank 10 in a stretching manner, and finally, the sheaths protect the components.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
