A control method for a washing machine of the present invention will be described with reference to fig. 6 and 7. Wherein fig. 6 is a main flow chart of the control method of the present invention; fig. 7 is a flowchart of a control method of the present invention in which the brake mechanism is turned on or off to place the caster in a moving state or a locked state.
As shown in fig. 6, the control method for a washing machine of the present invention includes the steps of:
s100, acquiring the state of the washing machine;
s200, judging whether the washing machine is in a working state or not;
s300, according to the judgment result of whether the washing machine is in the working state, the brake mechanism is selectively controlled to be opened or closed so that the caster is in the moving state or the locking state.
The state of the washing machine comprises a working state and a non-working state of the washing machine, and the working state of the washing machine can be other working states of washing, rinsing, spin-drying, upgrading, detecting, demonstrating and the like of the washing machine; the non-operating state of the washing machine may be a stop state, a standby state, or other non-operating states of the washing machine.
In step S100, the state of the washing machine may be acquired in real time; the state of the washing machine may also be acquired at preset time intervals. The preset time interval may be 10min, 20min, 30min, etc., and the preset time interval is only exemplary, but not limiting, and those skilled in the art may flexibly adjust and set the preset time interval according to the use frequency of the washing machine in practical applications, and in any case, the preset time interval may be adjusted and set as long as whether the washing machine is in the working state can be accurately determined.
As shown in fig. 7, in step S300, the step of selectively controlling the brake mechanism to be turned on or off to make the caster in the moving state or the locking state according to the determination result of whether the washing machine is in the operating state specifically includes:
s310, if the washing machine is in a working state, controlling the brake mechanism to be closed so as to enable the caster wheels to be in a locking state;
and S320, if the washing machine is in a non-working state, controlling the brake mechanism to be opened so as to enable the caster wheels to be in a moving state.
In step S310, if the washing machine is in a working state, for example, when the washing machine is in a spin-drying state, a washing tub of the washing machine rotates at a high speed, the washing tub may shake violently due to uneven stress, if the caster is in a moving state, the washing machine will be driven to move under the action of the violent shaking of the washing tub, and the tub collision phenomenon of the washing machine will be aggravated under the dual actions of the shaking of the washing tub and the movement of the washing machine; for another example, when the washing machine is in a drainage state, the washing machine drains water into the floor drain through the drain pipe, if the caster wheel is in a moving state, the washing machine is pushed under the action of external force, so that the drain pipe is pulled out from the floor drain, and the washing water is drained to the ground. In order to avoid the situation, the brake mechanism is controlled to be closed to enable the trundles to be in a locking state, so that the trundles cannot move and rotate when the washing machine is in a working state, the stability of the washing machine in the working process is guaranteed, and the user experience is improved.
It should be noted that, when the washing machine is in the working state, the caster is in the moving state to affect the operation stability of the washing machine, not limited to the above-mentioned cases, but also may be in the water filling state, the washing machine fills water into the washing tub through the water filling pipe, if the caster is in the moving state, the washing machine will be pushed when being subjected to the external force, so that the water filling pipe is disconnected from the external water source (for example, a faucet), and the washing water flows to the ground without being filled into the washing tub. In practical applications, a person skilled in the art can determine the situation that the caster in a moving state affects the operation stability of the washing machine according to the specific operation state of the washing machine.
In step S320, if the washing machine is in a non-operating state, for example, when the washing machine is in a stopped state or a standby state, a user wants to move and transport the washing machine, and if the caster is in a locked state, a large amount of manpower is required to move the washing machine.
It should be noted that, in the above process, step S310 and step S320 are not in sequence, are parallel, and are only related to the determination result of whether the washing machine is in the working state, and corresponding steps are executed according to different determination results.
Referring to fig. 8, a control method of the caster of the present invention in a locked state will be described. Fig. 8 is a flowchart of a control method of the caster of the present invention in a locked state.
As shown in fig. 8, in the case where the caster is in the locked state, the control method further includes:
s331, acquiring the displacement of the caster;
s332, judging whether the displacement is larger than a preset displacement or not;
s333, if the displacement is larger than the preset displacement, stopping the operation of the washing machine and sending out alarm prompt information;
and S334, if the displacement is less than or equal to the preset displacement, continuing to operate the washing machine.
In step S331, the displacement of the caster, that is, the displacement of the caster in the locked state is detected by the displacement sensor.
In step S333, if the displacement is greater than the preset displacement, for example, the preset displacement is 3cm, the detected displacement of the caster is 4cm, which is greater than the preset displacement, which indicates that the washing machine is severely shaken during the operation process, even if the caster is in the locked state, the caster is still displaced by 4cm, so as to avoid the washing machine from continuing to operate under the condition of severe shaking, stop the operation of the washing machine, send an alarm prompt message to prompt the user that the washing machine is severely shaken, so that the user can timely handle the washing machine, eliminate potential safety hazards, and improve the operation safety of the washing machine.
In step S334, if the displacement is smaller than or equal to the preset displacement, for example, the preset displacement is 3cm, the detected displacement of the caster is 1cm, which is smaller than the preset displacement, which indicates that the washing machine shakes during the operation process, but the washing machine shakes to a smaller extent without significantly affecting the current operation of the washing machine, and the washing machine continues to operate.
It should be noted that the above listed preset displacements are only exemplary, but not limiting, and those skilled in the art can obtain the preset displacement according to experiments and in combination with the load of the laundry in practical applications, for example, the preset displacement is any value between 3cm and 8cm, and in any case, the preset displacement is adjusted and set, as long as it can be determined whether to stop the operation of the washing machine and send out the alarm prompt message.
It should be noted that, in the above process, step S333 and step S334 are not in sequence and are parallel, and only relate to the determination result of whether the displacement of the caster is greater than the preset displacement, and the corresponding step may be executed according to different determination results.
