Definitions

  • a heating control system of a multi-drum washing machine comprises at least two sets of heating devices, and the heating control system further comprises at least two detection units which are correspondingly connected with the heating devices, wherein each detection unit is used for detecting heating information of the corresponding heating device and controlling at least one other heating device to be turned on/off according to the heating information.
  • the multi-drum washing machine described in this embodiment can acquire the heating information of the heating devices by respectively detecting the heating devices, and control the operation of the heating devices according to the heating information, so as to avoid potential safety hazards of the multi-drum washing machine caused by excessive power consumption when the plurality of heating devices run at the same time.
  • the detection units when the heating devices work, the detection units are triggered to generate a high level or a low level; and when the heating devices do not work, the detection units are triggered to generate a low level or a high level.
  • the embodiment realizes real-time detection of the heating devices through simple detection circuit hardware connection on a circuit of each heating device, thus reducing the calculation burden of the processor of the multi-drum washing machine; and according to this embodiment, the circuits are detected by using connection structures of circuit hardware, thereby simplifying the judging and processing of the processor so that the accuracy and sensitivity of the detection circuits are improved, reducing the data processing amount of the multi-drum washing machine and prolonging the service life of the processor of the multi-drum washing machine.
  • the heating devices in this embodiment are correspondingly connected with the detection units. Before the second heating device is turned on, the first heating device needs to be detected to ensure that the first heating device is not in a high-power working state, so that it is ensured that the high-power heating devices in the multi-drum washing machine do not operate at the same time and that the multi-drum washing machine runs safely.
  • each heating device comprises at least one heating unit 1 and a control unit 2 corresponding to the heating unit 1, one end of the heating unit 1 is connected with a first power supply, the other end of the heating unit 1 is connected with the control unit 2, and the other end of the control unit 2 is connected with a second power supply; wherein the control unit 2 is used for controlling the heating unit 1 to be turned on/off.
  • heating units When one heating device is provided with a plurality of heating units 1, the heating units are arranged in parallel.
  • the first detection unit also corresponds to the first control unit and the first heating unit, and the first detection unit detects the electric potential information on a circuit where the first heating unit and the first control unit are located, thereby obtaining a heating state of the heating unit 1.
  • each detection unit is arranged in parallel with the corresponding control unit 2 and is used for detecting electric potential information of at least one end of the control unit 2.
  • each heating unit 1 comprises one or any combination of a heating pipe, a heating wire, a heating rod and an electromagnetic induction heating ring; preferably, the heating unit 1 is a heating pipe.
  • each detection unit is a first detection circuit 3, and an input end of the first detection circuit 3 is arranged between and connected with the corresponding heating unit 1 and the corresponding control unit 2.
  • the capacitor C when the first power supply is higher than the second power supply and the control unit 2 is on, the capacitor C is triggered to discharge, and the output end outputs a low level.
  • the control unit 2 When the control unit 2 is off, the capacitor C is triggered to charge, and the output end outputs a high level.
  • a heating control system of a multi-drum washing machine comprises at least two sets of heating devices, and the heating control system further comprises at least two detection units which are correspondingly connected with the heating devices, wherein each detection unit is used for detecting heating information of the corresponding heating device and controlling the heating devices to be turned on/off according to the heating information.
  • Each detection unit is a second detection circuit 4, and the second detection circuit 4 is connected in parallel with the corresponding control unit 2; wherein one end of the second detection circuit 4 is arranged between the corresponding heating unit 1 and the corresponding control unit 2, and the other end of the second detection circuit 4 is arranged between the corresponding control unit 2 and the second power supply; and the second detection circuit and the corresponding control unit 2 form a closed loop.
  • each second detection circuit 4 comprises a second resistor R1 and a diode D, and the resistor R1 and the diode D are connected and form a closed loop with the corresponding control unit 2; and the second detection circuit 4 further comprises an optical coupler OC, the optical coupler OC is reversely connected with the diode D, a C pole of the optical coupler OC is connected with a third resistor R3 and an external power supply V+, and an E pole of the optical coupler OC is grounded.
  • the isolated detection circuits are mainly adopted, which can avoid the problem of detection errors in detection information of the detection units due to the interference of a circuit where the heating units 1 and the control units 2 are located.
  • the detection unit is connected in parallel with the control unit 2 to detect the circuit information of two ends of the control unit 2, and when the control unit 2 is on or off, an output end outputs a high level or a low level. The state of each control unit 2 is obtained, and then the on/off state of other control units 2 is controlled.
  • each second detection circuit 4 in this embodiment through reverse connection of the diode D and the optical coupler OC, specifically, through reverse parallel connection of the diode D and a light emitting diode in the optical coupler OC, the safety of the second detection circuit 4 is improved.
  • each control unit 2 comprises a knife switch and/or a relay switch.
