In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a damper control method, which is applied to an electronic control board in an air-cooled refrigerator, and may include the following steps:
step 101: storing a first number of reset steps corresponding to a single damper and a second number of reset steps corresponding to a double damper, wherein the second number of reset steps is greater than the first number of reset steps;
step 102: when the air-cooled refrigerator is powered on, receiving data which is sent by a display panel in the air-cooled refrigerator when the air-cooled refrigerator is powered on and carries an air door type identifier;
step 103: determining the type of the electric air door in the air-cooled refrigerator according to the type identification of the air door carried in the received data;
step 104: according to the determined type of the air door, the following operations are carried out:

or the like, or, alternatively,
when the air door type characterization of determining electric air door is two air doors, control step motor in the air-cooled refrigerator rotates the second number of steps that resets, so that electric air door resets.
The air door control method provided by the embodiment of the invention comprises the following steps: an electric control board in the air-cooled refrigerator stores a first reset step number corresponding to the single air door and a second reset step number corresponding to the double air doors, wherein the second reset step number is greater than the first reset step number; when the air-cooled refrigerator is powered on, receiving data carrying the air door type identification sent by a display panel in the air-cooled refrigerator when the air-cooled refrigerator is powered on; determining the type of the electric air door in the air-cooled refrigerator according to the type identification of the air door, and executing the following operations: when the type of the air door represents that the electric air door is a single air door, controlling a stepping motor in the air-cooled refrigerator to rotate for a first reset step number so as to reset the electric air door; or when the air door type represents that the electric air door is a double air door, controlling a stepping motor in the air-cooling refrigerator to rotate a second reset step number so as to reset the electric air door. The embodiment of the invention distinguishes the single air door and the double air doors and controls the motor to rotate according to the distinguishing, so that the resetting time of the single air door is favorably shortened, and the duration time of noise is shortened.
In detail, the display panel is used as a main control unit, and when the refrigerator is powered on every time, data carrying with the air door type identification can be sent to the electric control panel, so that the electric control panel can distinguish whether the electric air door is a single air door or a double air door according to the air door type identification.
In detail, when the air-cooled refrigerator is powered on, the number of times of sending the data to the electric control board can be more than one time. As such, the electronic control board may preferably determine the damper type based on the received first frame data.
Of course, in other embodiments of the present invention, the electronic control board may determine the type of damper based on the received data of the non-first frame.
In an embodiment of the invention, when the electric control board is powered on the air-cooled refrigerator, if the data sent by the display board is received, whether the data carries the air door type identifier or not can be judged, if yes, the received data can be considered to be correct data, the air door type identifier is read from the data, and if not, the received data can be considered not to be correct data. In addition, when the electric control board determines that the data is not correct data, whether communication faults exist at present can be further judged, if the electric control board has communication faults at present, the electric air door in the air-cooled refrigerator can be temporarily set to be a double air door, the rotation of the stepping motor is controlled according to the second reset step number, and the reset of the electric air door is executed in time, so that the normal operation of the air-cooled refrigerator is supported.
Of course, when the type of the electric air door is not accurately determined, if the data carrying the type identifier of the air door sent by the display panel is received again subsequently, the type of the electric air door in the air-cooled refrigerator can be accurately determined according to the type identifier of the air door.
In the embodiment of the invention, the air door type identification used for representing a single air door and the air door type identification used for representing double air doors can be prestored on the electric control board, and whether the electric air door is a single air door or a double air door is determined according to the prestored identification and the air door type identification in the received data.
For example, when the air-cooled refrigerator is powered on, the electronic control board detects normal communication for the first time, analyzes the communication data, and reads the damper flag bit in the communication data, wherein the logic is "1" which means double dampers, and the logic is "0" which means single damper.
In an embodiment of the present invention, the first number of reset steps may be 1859 steps, and the second number of reset steps may be 6300 steps. Because the second reset step number is greater than the first reset step number, the air door can be reset by distinguishing single and double air doors and giving the stepping motor proper step number.
In general, the purpose of resetting the electric damper when the air-cooled refrigerator is powered on can be to make the electric damper fully closed. After the electric air door is reset, when a specific air cooling requirement exists, the electric air door can be accurately opened to a certain angle according to the air door angle requirement corresponding to the specific air cooling requirement so as to meet the air door angle requirement.
Of course, in other embodiments of the present invention, the electrically operated damper may be reset to be fully open.
In detail, the damper motor step pulse correspondence table may be as shown in table 1 below.
TABLE 1
In Table 1, "A +, B +, A-, B-" may respectively characterize 4 coil ports, "+" may characterize a high level, and "-" may characterize a low level.
In the embodiment of the invention, when the air door is initialized, the air door motor can rotate Clockwise (CW), the rotation steps are the specified steps for completely closing the air door, and the aim is to completely close the air door.
In the embodiment of the invention, when the air door motor does not act, the air door motor is not electrified, and the air door does not need to be kept electrified.
In the embodiment of the invention, for the single-air-door type air-cooled refrigerator, when the electric control board in the single-air-door type air-cooled refrigerator executes the step 104, the operation of resetting the electric air door according to the first resetting step number is specifically executed; for the double-air-door type air-cooled refrigerator, when the electric control board in the double-air-door type air-cooled refrigerator executes the step 104, the operation of resetting the electric air door according to the second resetting step number is specifically executed.
In summary, in the embodiment of the present invention, the type of the single air door and the type of the double air doors are determined when the refrigerator is powered on, so as to distinguish whether the electric control board is connected with the single air door or the double air doors, and accordingly, the reset time of the air doors and the required steps of opening and closing the air doors can be correspondingly adjusted, so that the time for rotating the air doors is shortened compared with the existing implementation manner, and the duration time of the noise is reduced. Therefore, compared with the prior art, for the single-damper type air-cooled refrigerator, the damper control method provided by the embodiment of the invention can reduce the noise generated when the stepping motor in the refrigerator rotates, thereby reducing the noise of the refrigerator.
In general, when the air-cooled refrigerator runs for a long time, the frosting condition is easy to occur in the refrigerator. Under the refrigerator state of frosting, no matter what kind of state is in the air door, if the air door does not take place to rotate for a long time, for example 2h, thereby the unable normal rotation of the problem that easily appears being frozen, so, can regularly control the air door and accomplish once opening and shutting, if accomplish once opening and shutting of air door every 2h after the refrigerator is electrified.
Therefore, in an embodiment of the present invention, to prevent the electric damper from being unable to normally rotate due to frost formation inside the refrigerator, the method may further include: receiving a damper reset instruction periodically sent by the display panel after the air-cooled refrigerator is powered on;
when any throttle reset instruction is received, the following operations are executed:
when the electric air door is determined to be a single air door, controlling the rotation of a stepping motor in the air-cooled refrigerator based on the first reset step number so as to enable the electric air door to be opened and closed once;
or the like, or, alternatively,
and when the electric air door is determined to be a double air door, controlling the rotation of a stepping motor in the air-cooled refrigerator based on the second reset step number so as to enable the electric air door to complete one-time opening and closing.
In the embodiment of the invention, when the refrigerator is electrified, the electric control board determines the type of the electric air door in the refrigerator, so that the opening and closing of the air door can be directly controlled according to the determined type of the air door. That is, the opening and closing of the air door is controlled according to the first reset step number when the air door is determined to be a single air door, and the opening and closing of the air door is controlled according to the second reset step number when the air door is determined to be a double air door. The air door is controlled to be opened and closed periodically, so that the situation that the air door is frozen due to frosting inside the refrigerator and cannot rotate normally can be avoided, and a normal air cooling effect can be provided.
In the embodiment of the invention, because the type of the electric air door can be accurately judged, the opening angle of the electric air door can be controlled to a specific angle based on the type of the electric air door, so that corresponding air volume is provided.
Thus, in one embodiment of the invention, the method may further comprise: storing a first corresponding relation between the opening angles and the rotating steps corresponding to the single air door and a second corresponding relation between the opening angles and the rotating steps corresponding to the double air doors, wherein any one of the stored corresponding relations relates to at least three opening angles, and the at least three opening angles comprise an angle when the air door is fully opened and an angle when the air door is fully closed;
receiving a damper control instruction which is sent by the display panel after the air-cooled refrigerator is powered on and carries a target opening angle;
when the damper control instruction is received, the following operations are executed:
when the electric air door is determined to be a single air door, determining a first rotation step number corresponding to the target opening angle in the first corresponding relation, and controlling the rotation of a stepping motor in the air-cooled refrigerator based on the first rotation step number so that the electric air door has the target opening angle;
or the like, or, alternatively,
and when the electric air door is determined to be a double air door, determining a second rotation step number corresponding to the target opening angle in the second corresponding relation, and controlling the rotation of a stepping motor in the air-cooled refrigerator based on the second rotation step number so as to enable the electric air door to have the target opening angle.
In detail, the air quantity can be adjusted by adjusting the angle value of the air door, so that the given refrigeration requirement is met.
For example, the display panel may be preset with a refrigeration damper control rule, such as the rule may include: and when the refrigerating chamber is in a refrigerating period or the corresponding temperature reaches the starting point temperature, the air door is controlled to be opened, and the air door is specifically controlled to be opened to a specific angle according to other factors, such as target temperature, current temperature and the like. Therefore, the display panel can issue the air door control command carrying the opening angle of the air door to the electric control panel according to the rule when the air door needs to be controlled, so that the electric control panel can rotate the air door to the position according with the opening angle of the air door by executing the air door control command.
In the embodiment of the invention, in order to realize the control of the rotation angle of the electric air door to achieve the required specific air quantity, the electric air door can move at various angles instead of only in two states of full closing and full opening. For example, the air-cooled series single damper opening angle control rules stored in the electronic control board may be as shown in table 2 below.

In detail, the value of the opening angle may be set as desired according to the actual application, and is not necessarily the respective opening angles as shown in table 2.
