The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of the systems and methods of the present application as detailed in the appended claims.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for resetting a refrigerator damper in accordance with the related art of the present application. The method comprises two steps S101 and S102:
step S101, sending out a full-stroke opening signal to control the refrigerator air door to be completely opened;
step S102, sending out a closing signal larger than the full stroke.
The influence of the initial position of the air door body to the air door noise is not considered in this scheme, and the air door resets the initial position if not in the state of closing completely, and the in-process that resets, the door body is opened to extreme position and just has unnecessary step number, and the structure of the door body is spacing and the unnecessary drive signal of motor will make the door body of air door produce the shake to be accompanied by big noise, in addition, the air door body is opening the back completely, and the vibration of the door body is difficult to control relatively.
Fig. 2 is a noise representation of the refrigerator damper resetting method of the related art of the present application described in fig. 1.
Wherein the horizontal axis represents time and the vertical axis represents noise intensity in decibels.
As can be seen from fig. 2, 11.58s to 21.74s are the durations of the resetting process of a refrigerator damper, in which a peak of 46.01db noise occurs at 15.98s, and the average of the noise intensity during the resetting process is 42.06 db.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for resetting a damper of a refrigerator according to an exemplary embodiment of the present application.
As shown in fig. 3, the refrigerator damper resetting method may include the following steps S110 to S140.
And step S110, sending a damper reset signal, wherein the damper reset signal comprises a first reset signal, a second reset signal and a third reset signal.
It should be noted that, the opening or closing of the damper is controlled by the control element sending a damper control signal, and the control element does not have a function of identifying the position of the damper door body, so that the damper reset signal needs to be sent by the control element to reset the damper so as to ensure the accuracy of the initial position of the damper.
In one embodiment, the damper reset signal is sent, and the following scheme may be adopted: the damper reset signal is sent at predetermined intervals, illustratively, the damper is reset at fixed intervals, such as every hour, to accurately control the damper position.
In another embodiment, the time interval for the damper reset may be determined according to the usage time of the refrigerator, and illustratively, the longer the usage time of the refrigerator, the shorter the time interval for the damper reset, and the time point for sending the damper reset signal is not limited herein.
In this embodiment, the control element issues a damper reset signal when a time point preset to send the damper reset signal is reached, the damper reset signal including a first reset signal, a second reset signal, and a third reset signal. Each reset signal gives the direction of movement and the number of steps of movement of the damper for driving the damper to move a given number of steps in accordance with the direction of movement given by the respective reset signal.
The first reset signal, the second reset signal and the third reset signal are sent, in one embodiment, the following scheme may be adopted: sending a first reset signal; after the first reset signal is operated, sending a second reset signal; and after the second reset signal is operated, sending a third reset signal.
Specifically, each reset signal comprises a certain number of pulse signals, each pulse signal is sent by the control element, the stepping motor can be driven to rotate by a step angle through the driving part, when each pulse signal of the first reset signal is operated, the second reset signal is started to operate, and according to the same rule, the third reset signal is operated after the second reset signal is operated.
In another embodiment, the following scheme may also be adopted for the transmission of the first reset signal, the second reset signal and the third reset signal: after the first reset signal is sent, the first feedback signal after the first reset signal is operated is waited, after the first feedback signal is obtained, the second reset signal is sent, and similarly, the third reset signal can be sent according to the same rule.
It should be noted that, because the mechanical structure of the air door has a structural limit position, when each reset signal drives the air door to reach the mechanical structure limit position, if the redundant steps are not completed, the redundant driving force of the motor collides with the structural mechanical limit position, so that the air door is blocked and abnormal noise is generated, and the noise disappears until the motor completely runs the reset signal.
And step S120, determining a first direction and a first designated step number according to the first reset signal, and controlling the door body to move the first movement step number along the first direction until the door body is closed with the door frame, wherein the first movement step number is less than or equal to the first designated step number.
In this embodiment, the first reset signal may be a signal that is first sent by the control element, the first designated number of steps is a predetermined number of steps of movement of the door body, and in this embodiment, the first designated number of steps may be a number of steps required for the door body to be opened from the full state to the closed state, the first direction is a direction in which the door body is closed, and the first number of steps of movement is a number of steps actually moved by the door body from a current original position to a position in which the door body is closed with the door frame.
When the first reset signal is sent out, in more cases, the door body is in an unclosed state, namely the door body can be located at any position between the two mechanical structure limits of closing and opening, and after the driving part receives the first reset signal, the door body is controlled to be closed. Illustratively, if the throttle body has a 1750 step distance between two mechanical structure limits from closed to fully open. If the air door body has a distance of 1000 steps with the closed position of the door frame, but because the control element cannot sense the position of the air door body, the control element sends a first reset signal, the control door body moves 1750 steps towards the closing direction, the door body is closed with the door frame after moving 1000 steps, the closing signal of 750 steps is not finished, and the door body can collide the door frame to generate noise under the action of the redundant driving force of the motor. Therefore, when the door body is closed with the door frame, the vibration of the door body is easy to control. When the door body and the door frame are closed, the silencing strips can be arranged on the inner sides of the door frame and the door body, so that noise generated when the door body impacts the door frame under the action of redundant driving force of the motor is reduced.
In other embodiments, any method in the prior art may be used to reduce the noise generated when the door body impacts the door frame, and the method for reducing the impact noise is not limited herein.
After the step is finished, the air door can be closed no matter where the original position of the door body is, so that the control element can ensure the accuracy of the follow-up control of the air door to the air door control signal to control the movement of the air door while determining the position of the air door.
And step S130, determining a second direction and a second movement step number according to the second reset signal, and controlling the door body to move the second movement step number along the second direction and open the door frame to the limit position, wherein the second direction is opposite to the first direction.
A feedback signal may be provided to instruct the control component to send the second reset signal when the damper is in the closed state, or the control component may estimate the time required in step S120, and send the second reset signal when the preset time is reached, which is not limited herein.
The second direction is opposite to the first direction, and in this embodiment, the first direction is a direction in which the damper is closed, so that the second direction is a direction in which the damper is opened, and the second movement step number is a step number of the movement of the door body preset in the second reset signal.
In order to reduce the noise of the air door in the opening process, the second movement step number can be the same as the first designated step number and is the step number required by the door body from the closing position to the full opening position. Meanwhile, the air door can be ensured to be in a fully opened state after the operation of the step is finished.
And step S140, determining a first direction and a third appointed step number according to a third reset signal, and controlling the door body to move the third movement step number along the first direction until the door body is closed with the door frame again, wherein the third movement step number is less than the third appointed step number.
As described above, the first direction is a direction in which the damper is closed, the third designated number of steps is a number of steps designated when the control element sends the third reset signal, and the third movement number of steps is a number of steps in which the door body actually moves under the control of the third reset signal.
The third movement step number is smaller than the third designated step number, so that the air door can still return to the closed state even if the driving element fails, for example, the step number of the stepping motor is lost, the door body of the air door is frozen and other special conditions exist.
Illustratively, if the number of steps required to open and close the damper for a full stroke is 1750 steps, with the damper in the fully open position, the control provides 1850 steps of the close signal to the damper to control movement of the damper in the closing direction for 1850 steps, and the damper is closed when the damper moves 1750 steps. And the step can ensure that the air door can still return to a closed state even if the step number of the stepping motor is lost and the door body of the air door is frozen and other special conditions exist.
It is easy to understand, on the control to the air door is based on carrying out reliable reset to the air door basis, through closing the air door at first, reduce the vibration of air door in the position of easily controlling the air door vibration, like this, both can carry out reliable reset to the air door, also can not produce very obvious noise, and then influence customer's use and experience.
FIG. 4 is a noise performance of a refrigerator damper resetting method according to one embodiment of the present application.
As shown in fig. 4, it can be seen from the time history that the reset process of the refrigerator damper lasts from 18s to 34.37s, in which the peak noise is 41.83dB (occurring at 34.01 s) and the average noise intensity is 37.38 dB.
Comparing fig. 4 with fig. 2, it can be known that the noise performance of the resetting process of the refrigerator damper resetting method according to the present application is superior to the noise performance of the resetting process of the refrigerator damper resetting method according to the related art. The average noise in the resetting process of the air door resetting method is reduced from 42.06dB to 37.38dB, and the peak noise is reduced from 46.01dB to 41.83dB, although the air door resetting method operates for 5-6S more than the related technology, the noise of the technical scheme is relatively stable, and the working noise is not easy to cause user perception.
In another exemplary embodiment of the present application, after step S120 shown in fig. 3, the method may further include: when the door body and the door frame are closed, the position relation of the door body and the door frame is locked.
When the door body and the door frame are closed, the positions of the door body and the door frame can be locked, when the positions of the door body and the door frame are locked, the noise caused by the redundant driving force of the motor and the mechanical limit conflict of the structure can be effectively reduced, and the purpose of reducing the noise of the air door in the reset process is achieved.
Referring to fig. 5, fig. 5 is a noise performance of a refrigerator damper resetting method according to an embodiment of the present application using a specific gear mechanism.
As shown in fig. 5, the refrigerator damper reset process continued from 28.19s to 44.45s, with a peak noise of 35.96db appearing at 43.95 s. The average noise intensity was 34.59 db.
Comparing fig. 5 with fig. 2, it can be seen that the noise performance of the resetting process of the refrigerator damper resetting method using the specific gear transmission mechanism is superior to that of the resetting process of the refrigerator damper resetting method in the related art. The average noise of the air door in the whole operation stage is reduced to 34.59dB from 36.29dB, the peak noise is reduced to 35.96dB from 38.78dB, the whole reset process is 5-6S more than that in the related technology, but the noise is relatively stable, the jitter degree of the sound quality of the air door can be effectively reduced, and the user experience is improved.
From this, the technical scheme that this application adopted sends first reset signal earlier, closes the door body at first, and the second part sends the second reset signal, opens the door body full stroke, and at last, sends for the air door third reset signal, carries out the closing that is greater than the full stroke, carries out reliable the reseing to the air door in the position of easily controlling the air door vibration, can not produce very obvious noise simultaneously. The advantages of the technical solution adopted in the present application are more apparent by comparison with the related art.
In another embodiment of the present application, based on the method for resetting a damper of a refrigerator shown in fig. 3, the first designated number of steps is the same as the second number of steps of the movement, and the third designated number of steps is the sum of the first designated number of steps and the preset number of steps. The first designated number of steps may be the same as the second designated number of steps, and as described above, the first designated number of steps is the set number of steps of the movement of the door body, and is used to close the door body from any initial position to the door frame, and the second designated number of steps is also the set number of steps of the movement of the door body, and is used to close the door body from the position where the door body is closed to the position where the door body is fully opened. In order to ensure that the door body is closed from any initial position, the first designated number of steps can be set as the number of steps required by the door body from full opening to full closing. The third designated number of steps is set to allow the door body to move from the fully opened position to the position where the door body is closed again with the door frame, and the third designated number of steps may be slightly larger than the first designated number of steps, illustratively larger than a fixed preset number of steps, for example, 100 steps or 50 steps, and the like. Thus, even in the special condition of freezing of the air door and the like, no obvious abnormal sound is generated, and the air door can still be normally closed.
