Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings.
The first embodiment is as follows:
a control method of a washing machine, comprising:
step 1: after the washing machine is powered on, continuously counting the pressing times M of the 'start/pause' key, and judging whether the pressing times M of the 'start/pause' key is an even number: if so, immediately stopping the inner barrel from rotating; if not, performing the step 2;
the door switch can immediately stop rotating the inner barrel through the step no matter whether the door switch fails or not, and the door switch is matched with a means for controlling the inner barrel to stop rotating to form double protection, so that the safety factor of a user using the washing machine is greatly improved, and the safety of the user is guaranteed.
Step 2: whether the washing machine door switch is on is detected through the arranged door switch detection circuit: if yes, starting the motor; if not, alarming.
The step is to judge the on-state of the washing machine door switch before starting the running motor, in order to ensure the use safety of a user, when the on-state of the washing machine door switch cannot be detected, the motor is not started, and an alarm is also sent to remind the user, wherein the two conditions are included at the moment: one is that the door switch is broken, so the door switch can not be detected to be switched on; the other is that the operator does not close the washing machine door.
Example two:
as shown in fig. 2, the present invention provides a control method of a washing machine, including:
step 1: judging whether the 'start/pause' key is pressed and touched: if yes, recording the pressing times M and performing the step 2; if not, returning to the step 1;
every time the 'start/pause' key is pressed and touched, the sensor connected with the key can transmit signals to a counter arranged on the controller, and the value accumulated on the counter is always overlapped and not emptied from the time when the power supply signal is detected to the time when the power supply is disconnected. Even after a period of washing or drying, the user may press and activate the "start/pause" key several times by throwing the laundry into the washing tub, and the number of pressed and activated times is accumulated on the counter. Therefore, the condition that the pressing touch is performed for odd times and the operation state of the inner barrel is corresponding to the operation state, namely the starting state, can be ensured; even number of pressing touch should correspond to the inner barrel stop state, i.e. "pause" state.
Step 2: judging whether the pressing times M of the 'start/pause' key is an even number: if so, the inner barrel stops rotating immediately; if not, performing the step 3;
although the existing washing machine is provided with a door switch, and the door switch action is controlled by opening the door of the washing machine to force the inner tub of the washing machine to stop rotating, once the door switch of the washing machine fails: no matter whether the door of the washing machine is opened or closed, the door switch is always in a closed state, the inner barrel of the washing machine cannot be forced to stop rotating, and the user opens the door of the washing machine under the condition that the inner barrel rotates, so that clothes in the inner barrel can be thrown out, and the personal safety of the user is caused. The washing machine using the method not only utilizes the door switch of the washing machine to control the inner barrel to stop rotating immediately, but also utilizes the control method provided by the invention to control the inner barrel to stop rotating immediately, thus reducing the risk of threatening the personal safety of users by two modes. When the number M of times of pressing the 'start/pause' key is judged to be an even number (M is a natural number), the inner barrel is controlled to stop rotating immediately, and the use safety of the washing machine can be effectively improved.
And step 3: whether the washing machine door switch is on is detected through the arranged door switch detection circuit: if yes, starting the motor; if not, alarming and carrying out step 4;
if the detected pressing times M are odd numbers, namely the inner tub is required to be in a starting state, the inner tub is required to work, the door of the washing machine is required to be in a closing state, namely the door switch is required to be in a switching-on state, and therefore the risk that the clothes are thrown out cannot occur; if the washing machine door switch is not in the on state, there are two cases: first, the user presses the "start/pause" key an odd number of times without closing the washing machine door; second, although the user closes the washing machine door, the washing machine door switch fails and is always in an off state. In both cases, if the inner tub is still rotated, there is a risk that laundry is thrown out of the washing tub. In order to prevent the above situation, if the door switch is not detected to be switched on, the motor is not started, and corresponding alarms are carried out, wherein the alarms comprise a buzzer alarm and an indicator lamp flashing alarm. Specifically, the buzzer alarm will be more and more urgent along with the extension of the alarm time, and the frequency of the flashing of the indicator light will be faster and faster along with the extension of the alarm time.
And 4, step 4: the timer starts timing, the alarm duration time T is obtained, and whether the alarm duration time T reaches the preset alarm duration time T0 is judged: if yes, the power is cut off; if not, performing the step 5;
and 5: judging whether the washing machine door switch is on: if yes, starting the motor and stopping alarming; if not, returning to the step 4.
In the first case that the door switch of the washing machine is not in the on state and the door switch of the washing machine is not in failure, the operator can start the motor and stop the alarm by closing the door of the washing machine, so that the inner tub operates normally. However, a preset alarm time period T0 is required to be limited, that is, the user takes a door closing action within a time range T0 to enable the washing tub to normally operate; if the time T0 is exceeded, it is determined that the washing machine door switch has failed even if the user does not perform the opening and closing operation for a long time for the safety of the user, and the power-off process is performed on the washing machine. The specific preset alarm time period T0 may be set according to the usage habits of different users, and the preset alarm time period T0 in this embodiment is 2 minutes.
Example three:
a washing machine is applied to the washing machine control method and is used for solving the problem that the safety is low because the inner barrel of the washing machine stops rotating immediately through single door switch detection control, and the washing machine is matched with a means for controlling the inner barrel to stop rotating by using a door switch to form double protection, so that the safety coefficient of a user using the washing machine is greatly improved, and the safety of the user is guaranteed.
It is noted that the foregoing shows and describes the general principles and features of the present invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the present invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined by the appended claims and their equivalents.
