Example two
The present embodiment further optimizes the door opening and closing control method of the drawer-type household appliance described in the first embodiment on the basis of the first embodiment. Fig. 3 is a flowchart of a method for controlling opening and closing of a door of a drawer type home appliance according to the present embodiment, and the method is described in detail with reference to fig. 3, which is as follows.
The method comprises the steps that firstly, a controller obtains a door closing signal and a door opening signal in real time, and controls a first electromagnetic coil and a second electromagnetic coil to be electrified to enable a drawer to act when the door closing signal or the door opening signal is obtained.
The dishwasher in the embodiment is provided with an opening button for opening the drawer 2 and a closing button for closing the drawer 2, the opening button and the closing button are both connected to the controller, and the controller receives a door opening signal or a door closing signal when the opening button or the closing button is pressed.
After the dishwasher completes one washing, the drawer 2 is opened to facilitate the user to take out the dishes. Therefore, the signal that the corresponding dishwasher is finished after the dishwasher finishes washing each time can be obtained as the door opening signal.
When the controller acquires a door closing or opening signal, the first electromagnetic coil 32 and the second electromagnetic coil 34 are energized, so that an attractive force or a repulsive force is generated between the drawer 2 and the appliance body 1, and the drawer 2 starts to operate.
Step two, taking the minimum current which can enable the drawer to act when the drawer is in no-load as the initial current to provide attraction force or repulsion force for enabling the drawer to act, judging whether the speed of the drawer is zero or not, if so, enabling the drawer not to act, and executing the step three; if not, the dishwasher starts to operate and executes the fourth step.
And step three, gradually increasing the current to increase the attractive force or the repulsive force until the drawer acts, and then executing step four.
In this embodiment, the initial current is changed by increasing a predetermined current value in a unit time, the initial current is recorded as I, the predetermined current value is Δ I, and the minimum current is recorded as I 0 If the initial current value is equal to I 0 + N × Δ I, where N ═ 1, 2, 3.
In order to avoid the problem that the tableware in the drawer 2 is collided due to the sudden and excessive increase of the speed of the drawer 2, the preset current value delta I is not too large, so that the drawer is slowly accelerated after starting to act; the specific magnitude of the predetermined current value Δ I may be determined from a number of repeated experiments.
And step four, continuing to operate at the current until the speed of the drawer reaches a first preset speed, and changing the current direction to enable the drawer to perform deceleration movement.
Since the maximum static friction force when the drawer 2 is unloaded is equal to the sliding friction force when the drawer 2 is unloaded in this embodiment, in the process of continuously operating at the current, the attraction force or the repulsion force applied to the drawer 2 is equal to the maximum static friction force, so that the drawer 2 moves at a constant speed.
Through speed sensor real-time detection drawer 2's speed, when drawer 2's speed reaches first predetermined speed, change the electric current direction and make drawer 2 receive the effect of opposite power, begin to do deceleration movement, be used for slowing down for drawer 2 provides enough distance, the moving speed is too big when avoiding limit switch 41 to touch first spacing post 42 or the spacing post 43 of second, cause drawer 2 to stop suddenly and lead to the collision violent, make the tableware in the drawer 2 take place the damage because of violent the collision.
And step five, judging whether the limit switch is closed or not, and if so, completely closing or completely opening the drawer.
In the process of moving the drawer 2, if the limit switch 41 touches the first limit post 42 or the second limit post 43, the limit switch 41 will be closed, which indicates that the drawer 2 is completely closed or completely opened.
In the process of decelerating the drawer 2, when the limit switch 41 needs to be ensured to be closed, the current speed of the drawer 2 is less than or equal to a second preset speed; through setting up the second and predetermineeing speed for when drawer 2 stopped to move, the speed of drawer 2 is just for zero or speed is less, can not produce violent striking. The magnitude of the second preset speed can be determined by a number of repeated experiments.
In this embodiment, when the drawer 2 is in the closed state during the operation of the dishwasher, the first solenoid coil 32 and the second solenoid coil 34 are both energized to lock the drawer 2. At this time, attractive force of mutual attraction is generated between the drawer 2 and the electric appliance body 1, but the attractive force is smaller than the current maximum static friction force of the drawer 2, so that the phenomenon that the drawer 2 is required to move due to overlarge force and cannot move due to the action of the first limiting column 42 is avoided, and the effect of protecting the limiting switch 41 and the first limiting column 42 is achieved.
And because the dish washer is in operating condition, through producing the appeal of inter attraction between drawer 2 and the electric body and make drawer 2 be in the locking condition, avoid because of the people causes washing water outflow or opens drawer 2 and scald the user in the stoving process of mistake opening drawer 2.
When the dishwasher is not in operation, the first switch and the second switch are both in an open state, namely the first electromagnetic coil 32 and the second electromagnetic coil 34 are both in a power-off state, so that the electricity is saved, and the problem of electric shock caused by the fact that the first electromagnetic coil 32 and the second electromagnetic coil 34 are touched manually can be avoided.
Example two
The difference between the first embodiment and the second embodiment is that, as shown in fig. 4, after the drawer moves, the current increases by a preset current value within a unit time, and when the speed of the drawer reaches a first preset speed, the current direction is changed to decelerate the drawer.
For dishwashers of different models, due to different movement strokes of the drawer, the method can be adopted for dishwashers with larger movement strokes of the drawer, the closing or opening time of the drawer can be effectively reduced, and the working efficiency is improved.
EXAMPLE III
The difference between the embodiment and the first embodiment is that after the drawer moves, the drawer can also move according to the changing trend of acceleration, uniform speed and deceleration. Specifically, referring to the flowchart shown in fig. 5, after the drawer operates, the current is changed by increasing a preset current value in a unit time, and the drawer moves for a preset time, and then the drawer operates with a stable current until the speed of the drawer reaches a first preset speed, and then the current direction is changed to decelerate the drawer. The preset time is determined according to multiple tests, and the preset time corresponding to different models of dishwashers can be different.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
