Description

This application is filed by Guangdong Midea Refrigeration Equipment Co., Ltd. and Midea Group Co., Ltd. on August 6, 2018, entitled "Filter control method, air conditioner and computer readable storage medium", Chinese Patent Application No. of the Chinese patent application entitled "Filter control method, air conditioner and computer readable storage medium" with Chinese patent application number "201810888226.8". priority is claimed, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD The present application relates to the technical field of air conditioners, and more particularly to filter control methods, air conditioners and computer-readable storage media.

In conventional air conditioners, before the indoor air is heat-exchanged with the indoor heat exchanger, the operation stability of the air conditioner indoor unit is improved. To avoid dust or impurities in the air from entering the interior of the indoor heat exchanger, filters are installed in air conditioners.

With the operation of the air conditioner, the dust on the filter gradually accumulates, and the filter needs to be cleaned regularly for cleanliness and health. Filter cleaning methods include manual cleaning and automatic cleaning. Manual cleaning requires removing the panel of the air conditioner, taking out the filter, cleaning it, and reinstalling it after cleaning. When the filter is automatically cleaned, the dust on the filter can be removed by the cleaning mechanism of the air conditioner itself. By sweeping out, the purpose of cleaning is achieved.

However, in the case of using an air conditioner that automatically cleans the filter, in most cases, the cleaning process is directly performed, that is, the cleaning mechanism rotates to drive the filter winding operation to clean the filter.

FIG. 3 is a structural schematic diagram of the filter position at each stage in the filter cleaning process of the air conditioner of the present application, FIG. FIG. (c) is a structural schematic diagram showing the filter at the maximum transfer position.

In this embodiment, this filter control method is applied to an air conditioner in which the filter 10 is installed. The air conditioner includes a brush 30 for cleaning the filter 10 and a stepping motor (not shown) for controlling the brush 30. ) and a rubber strip 40 combined with the brush 30 are provided.

Gears are installed on both sides of the filter 10 and both sides of the brush 30 , and the gears on both sides of the filter 10 are engaged with the gears on both sides of the brush 30 to drive the filter 10 with the brush 30 .

In FIG. (a), when the filter 10 is in the initial position, this filter 10 presses the detection module 20 (detection switch) and causes the detection switch to change to the minimum configuration, and in FIG. When rotating in the forward and reverse directions, the stepping motor drives the filter 10 through the brush 30 so as to wind to this intermediate position, and in FIG. , the filter 10 is at the maximum transfer position, and if the stepping motor continues to rotate in the positive direction at this time, the filter 10 may fall off, causing the filter 10 to return to its normal position and return to its initial position. You will not be able to return to

When cleaning the filter, the stepping motor rotates in the forward direction, and the gear on the brush 30 drives the gear on the filter 10 to transfer the filter 10 so that the filter 10 moves from the initial position in FIG. It gradually moves to the position in FIG. (b) and finally moves to the maximum transfer position in FIG. The filter 10 is driven (forwarded) to rotate in the direction to return the filter 10 to the initial position in (a), at which time one cleaning process is completed.

In both transfer and forwarding processes, the rubber strip 40 rotates in the positive direction, and the fine bristles on the brush 30 poke into the mesh of the filter 10 to push out dust adhering to the filter 10, and the rubber strip 40 is pushed out. Rotate to scrape the protruding dust into the dust collection box, thus achieving the purpose of cleaning the filter 10 . The forward rotation is counterclockwise rotation, and the reverse rotation is clockwise rotation. 40 both rotate clockwise when rotating in the reverse direction.

In addition, this air conditioner is further installed with a detection module 20 for detecting the filter 10, this detection module 20 is installed at one end far away from the brush 30 of the filter 10 in the initial position, and this detection module 20 is contact It can be a sensor, a pressure sensor or a sensing switch.

Assuming that the detection module 20 is a contact sensor, when the filter 10 contacts this contact sensor, this contact sensor detects a contact signal and sends this contact signal to the controller of the air conditioner. , it can be determined that the detection module 20 (contact sensor) has detected the filter 10 .

If the detection module 20 is a pressure sensor, when the filter 10 presses the pressure sensor, the pressure signal detected by the pressure sensor increases, and the pressure sensor sends the detected pressure value to the controller of the air conditioner in real time. , and the controller can determine whether the sensing module 20 (pressure sensor) has sensed the filter 10 by this pressure value. For example, one pressure threshold is set, and when the pressure value detected by this pressure sensor is greater than this pressure threshold, it is determined that the detection module 20 (pressure sensor) has detected the filter 10 .

Assuming that the detection module 20 is a detection switch, when the filter 10 presses the detection switch, it transmits a pressing signal. It is determined that it has been detected. The detection switch is an elastic switch, and when the filter 10 gradually presses the detection switch, the pressure of the filter 10 gradually increases, so that the pressure switch is gradually pressed, and the filter 10 is completely initialized. It is possible to return the filter 10 to its position, and furthermore, to realize the complete position return of the filter 10. - 特許庁In this embodiment, the detection module 20 is used as a detection switch in order to reduce the cost of the air conditioner.

The filter 10 control method of the present application includes the filter 10 position confirmation, the detection module 20 confirmation process, the filter 10 cleaning process, and the filter 10 position correction process, and this embodiment is the filter 10 cleaning process.

This filter control method includes the following steps.
Step S110: Circularly perform the transfer operation for the filter and the forwarding operation for the filter, and update the forwarding number of the forwarding operation.

In this embodiment, when cleaning the filter 10, first, the transfer operation for the filter 10 and the forwarding operation for the filter 10 are cyclically executed, and when the forwarding operation is executed, the forwarding number of the forwarding operation is updated. As a concrete execution procedure, transfer operation-forwarding operation-transfer operation-forwarding operation. . . is. When carrying out the transfer operation, the stepping motor rotates in the positive direction to drive the brush 30 to rotate in the positive direction, so that the filter 10 is transferred by the brush 30, and the moving direction of the filter 10 is The direction is from the initial position to the maximum cleaning position. As shown in FIG. 3, when the stepping motor rotates in the forward direction, the stepping motor drives the brush 30 to rotate counterclockwise to perform forwarding operation. When running, the stepping motor rotates in the opposite direction to drive the brush 30 to rotate in the opposite direction, so that the brush 30 advances the filter 10, at this time, the moving direction of the filter 10 is the maximum cleaning position. to the initial position, and as shown in FIG. 3, when the stepping motor rotates in the opposite direction, the stepping motor drives the brush 30 to rotate clockwise.

Specifically, the transfer operation includes transferring the filter 10 by the brush 30 by controlling a stepping motor to rotate forward according to a first predetermined angle, and the forward operation includes a second predetermined angle. By controlling the stepping motor to rotate in reverse direction based on the angle, the brush 30 advances the filter 10, wherein the first predetermined angle is greater than the second predetermined angle.

The first predetermined angle is the rotation angle of the rotating shaft of the stepping motor, and the rotating shaft can rotate synchronously with the brush 30, that is, when the rotating shaft rotates by the first predetermined angle, the brush 30 rotates at the same time as the first predetermined angle. It rotates by a predetermined angle, and in another embodiment, the rotating shaft can rotate asynchronously with the brush 30, that is, the rotating angle of the rotating shaft and the rotating angle of the brush 30 have a proportional relationship.

The first predetermined angle is greater than the second predetermined angle, the first predetermined angle can be set to 130 degrees, 150 degrees, and the second predetermined angle can be set to 90 degrees, 110 degrees, etc. accordingly.

By making the first predetermined angle larger than the second predetermined angle, the transfer amount of the filter 10 each time is made larger than the forwarding amount, and the filter 10 is prevented from returning to the initial position again.

Step S120, when the number of forwarding times after updating reaches the first predetermined threshold and the forwarding operation is completed, controlling the stepping motor to rotate in the forward direction, and rotating the rubber strip in the forward direction; to control.

The first predetermined threshold can be reasonably set according to the initial value of the forwarding count, for example, if the initial value of the forwarding count is 0, the first predetermined threshold can be set to 3;

In this embodiment, when the number of times of forwarding after updating reaches the first predetermined threshold and the forwarding operation is completed, the filter 10 and the brush 30 are both moved completely after a plurality of times of transporting and forwarding to the filter 10. When cleaning the filter 10, there is a problem that the movement speed of the filter 10 and the rotation speed of the stepping motor do not match. do not do. In this case, the stepping motor is controlled to rotate in the forward direction, the rubber strip 40 is controlled to rotate in the forward direction, and the stepping motor drives the brush 30 to rotate in the forward direction. 30 is now driven to wind the filter 10 in the forward direction, and the thin hairs on the brush 30 poke into the mesh of the filter 10 to push out the dust adhering to the filter 10, and the rotation of the rubber strip 40 The purpose of cleaning the filter 10 is achieved by scraping the protruded dust into the dust collection box.

Step S130: Control the stepping motor to rotate in the reverse direction when it is detected that the forward rotation angle of the stepping motor reaches the maximum transfer angle.

In this embodiment, when it is detected that the forward rotation angle of the stepping motor reaches the maximum transfer angle, the stepping motor is controlled to rotate in the reverse direction, and the stepping motor rotates the brush 30 in the reverse direction. While driving to rotate, the brush 30 is now driven to wind the filter 10 in the opposite direction, and the fine bristles on the brush 30 poke into the mesh of the filter 10 and push out the dust adhering to the filter 10. At the same time, the rotation of the rubber strip 40 scrapes the protruding dust into the dust collection box, thus achieving the purpose of cleaning the filter 10 .

This maximum transfer angle is the rotation angle of the stepping motor when the filter 10 moves from the initial position to the maximum cleaning position - the first predetermined threshold value x (the difference between the first predetermined angle and the second predetermined angle). To prevent the filter 10 from being unable to be forwarded due to a situation such as dropping of the filter 10 by assuring that the winding amount of the filter 10 is not excessive.

Step S140: When detecting that the reverse rotation angle of the stepping motor reaches the maximum forwarding angle, control the stepping motor to stop operation.

In this embodiment, when the reverse rotation angle of the stepping motor reaches the maximum forwarding angle, the filter 10 has already returned to its original position, that is, the filter 10 is now at the initial position, so that the stepping motor is stopped. It controls and even completes the cleaning of the filter 10 .

Moreover, in one embodiment, after step S140, the filter control method further includes the following steps.
controlling the rubber strip to rotate in the reverse direction, controlling the rubber strip to stop rotating when the duration of the reverse rotation of the rubber strip reaches a predetermined time, and the forwarding number of times; reset.

When the stepping motor stops, the rubber strip 40 is controlled to rotate in the reverse direction, and when the duration of the reverse rotation reaches a predetermined time, the rotation of the rubber strip 40 is stopped to remove dust. can ensure that all the dust particles are scraped into the dust collection box, and resetting the forwarding times facilitates the smooth execution of subsequent cleaning operations.

Resetting the forwarding count means setting the forwarding count to a corresponding initial value, which can be an arbitrary constant. For example, when the initial value is 0, resetting the forwarding count means setting the forwarding count to 0. In other embodiments, the number of forwards can be reset at any time after turning on the power of the air conditioner and before updating the number of forwards in the forwarding operation.

As a filter control method proposed by this embodiment, a transfer operation for the filter and a forwarding operation for the filter are cyclically executed, the number of forwarding operations for the forwarding operation is updated, and the number of forwarding operations after the update is set to the second number. When a predetermined threshold is reached and the forwarding operation is completed, controlling the stepping motor to rotate in the forward direction and controlling the rubber strip to rotate in the forward direction, then the stepping when detecting that the forward rotation angle of the motor reaches the maximum transfer angle, controlling the stepping motor to rotate in the reverse direction, and the reverse rotation angle of the stepping motor reaches the maximum forwarding angle; When this is detected, the stepping motor is controlled to stop operating, and the transfer operation and forwarding operation are cyclically performed, so that both the filter and the brush are completely movable, that is, the filter A situation where the fit between the gear and the gear of the brush is good, and when cleaning the filter, the movement speed of the filter and the rotation speed of the stepping motor do not match, which causes the winding speed of the filter to be relatively slow. was not present, improving the cleaning efficiency of the filter. And by controlling the stepping motor to rotate to the maximum transfer angle to ensure complete cleaning of the filter, by controlling the stepping motor to rotate to the maximum forwarding angle, the filter will be cleaned when the cleaning is completed. To guarantee return to an initial position, facilitate the subsequent cleaning of a filter, and improve the cleaning efficiency of the filter.

Based on the first embodiment, a second embodiment of the filter control method of the present application is proposed. In this embodiment, the air conditioner is further installed with a detection module 20 for detecting the filter, and the filter control method further includes the following steps.
Step S150, determine whether the rubber strip is rotating when receiving the start/stop command.

Step S160, when the rubber strip is rotating, control the rubber strip to stop rotating and determine whether the detection module detects the filter; When the rotation stops, it is determined whether the detection module has detected the filter.

Step S170, if the detection module detects the filter, control the stepping motor to rotate in the reverse direction according to a third predetermined angle;

Step S180: when detecting that the reverse rotation angle of the stepping motor reaches a third predetermined angle, control the stepping motor to stop operation and perform the operation corresponding to the start/stop command; do.

In this embodiment, when it is ensured that the rubber strip 40 has stopped rotating, it is determined whether the detection module 20 has detected the filter 10; The motor is controlled to rotate in the reverse direction, the stepping motor is controlled to rotate in the reverse direction to ensure that the rubber strip 40 is not rotating, and the brush 30 is also controlled to rotate in the reverse direction. , the brush 30 forwards the filter 10 . When detecting that the reverse rotation angle of the stepping motor reaches a third predetermined angle, the stepping motor is controlled to stop running, and an operation corresponding to the start/stop command is performed. As a result, when the filter 10 returns to its position, the operation corresponding to the start/stop command is performed, and when the air conditioner is turned on/off, the filter 10 is ensured to be in the initial position, so that the following operation can be performed. Facilitates cleaning of the filter 10.

The third predetermined angle can be reasonably set, for example, the second predetermined angle can be set to 200 degrees, 250 degrees, and so on.

In this embodiment, after performing the operation corresponding to the start/stop command, if the start/stop command is the start command, the air conditioner is started and operated, and then the step of cleaning the filter in the present application is repeated. If the start/stop command is a stop command, the step of cleaning the filter in the present application will be performed again after the air conditioner is stopped or next time it is started and operated.

According to the filter control method proposed by this embodiment, when receiving the start/stop command, the detection module determines whether the filter is currently detected, and the detection module detects the filter. Then, by controlling the stepping motor to rotate in a reverse direction based on a third predetermined angle, the filter is forwarded by the brush, and the reverse rotation angle of the stepping motor is a third When it is detected that a predetermined angle has been reached, the stepping motor is controlled to stop operation, and an operation corresponding to the start/stop command is executed, and before the start/stop command is executed, the filter is turned off. Returning to the initial position facilitates subsequent cleaning of the filter and further improves the efficiency of cleaning the filter.

Based on the second embodiment, a third embodiment of the filter control method of the present application is proposed. In this embodiment, the filter control method further includes:
step S190 of forwarding the filter by the brush by controlling the stepping motor to rotate in a reverse direction if the detection module fails to detect the filter;
a step S200 of determining in real time whether the detection module detects the filter during the reverse rotation of the stepping motor;
When the detecting module determines that the filter has been detected, and detects that the reverse rotation angle of the stepping motor reaches a third predetermined angle after detecting the filter, the stepping motor is stopped. and a step S210 of controlling to and performing operations corresponding to the activation/deactivation instructions.

In this embodiment, if the detection module 20 fails to detect the filter 10 when the rubber strip 40 stops rotating, the stepping motor is controlled to rotate in the reverse direction, so that the brush 30 moves in the reverse direction. Rotation is driven, and the filter 10 is forwarded by the brush 30 . When the detection module 20 detects the filter 10 in the course of the stepping motor rotating in the reverse direction, it controls the stepping motor to rotate in the reverse direction again by a third predetermined angle, and then stops the stepping motor. and perform operations corresponding to the start/stop commands to ensure that the filter 10 returns to its initial position.

According to the filter control method proposed by the present embodiment, when the detection module fails to detect the filter, the stepping motor is controlled to rotate in the reverse direction to forward the filter by the brush, Subsequently, in the process of rotating the stepping motor in the reverse direction, it is determined in real time whether the detection module has detected the filter, and if it is determined that the detection module has detected the filter, the filter after detecting that the reverse rotation angle of the stepping motor reaches a third predetermined angle, controlling the stepping motor to stop operation, and performing an operation corresponding to the start/stop command Returning the filter to its initial position prior to executing the run, start/stop command facilitates subsequent cleaning of the filter and improves filter cleaning efficiency. When the filter is detected while the stepping motor is rotating in the reverse direction, the stepping motor is controlled to rotate in the reverse direction by a third predetermined angle to ensure that the filter returns to its initial position. This avoids the situation where the teeth between the filter and the brush are crooked or out of position.

Based on the third embodiment, a fourth embodiment of the filter control method of the present application is proposed. In this embodiment, after step S200, the filter control method further includes:
updating the number of reverse rotations of the stepping motor when it is determined that the detection module fails to detect the filter and the reverse rotation angle of the stepping motor reaches the maximum forwarding angle in step S220;
a step S230 of continuing to perform the step of forwarding the filter by the brush by controlling the stepping motor to rotate in the reverse direction if the updated number of reverse rotations is equal to or less than a second predetermined threshold; include.

In this embodiment, when the reverse rotation angle of the stepping motor reaches the maximum forwarding angle, if the filter 10 is still not detected, the reverse rotation number of the stepping motor is updated, that is, the current reverse rotation number to get the number of backward rotations after update. If the updated number of reverse rotations is less than or equal to the second predetermined threshold, continue executing step S190, and further, if the winding speed of the filter 10 is relatively slow, allow the filter 10 to return to the initial position.

The second predetermined threshold can be reasonably set according to the initial value of the number of reverse rotations, for example, when the initial value of the number of reverse rotations is 0, the second predetermined threshold can be set to 3.

Moreover, in one embodiment, after step S220, the filter control method further controls to stop the stepping motor if the updated number of reverse rotations is greater than a second predetermined threshold; outputting one fault information, resetting the number of reverse rotations, and performing operations corresponding to the start/stop instructions.

if the updated reverse rotation frequency is greater than a second predetermined threshold, controlling the stepping motor to stop operation and outputting first failure information to reset the reverse rotation frequency, i.e. reverse After setting the direction rotation number to the initial value, the operation corresponding to the start/stop command is executed. Specifically, the first failure information can be displayed on the display of the air conditioner, or if the air conditioner is already connected to the network, the first failure information can be sent to the default terminal, such as the user's terminal. Alternatively, it may be transmitted to the repairman's terminal.

The first failure information includes sensing module failure information, filter failure information and gear mesh failure information between the brush and the filter.

According to the filter control method proposed in this embodiment, when it is determined that the detection module fails to detect the filter and the reverse rotation angle of the stepping motor reaches the maximum forward rotation angle, the stepping motor updating the number of reverse rotations, and then controlling the stepping motor to rotate in the reverse direction when the updated number of reverse rotations is less than or equal to a second predetermined threshold, thereby causing the brush to rotate the filter; If the filter winding speed is relatively slow, the filter is returned to the initial position by controlling the stepping motor to rotate in the opposite direction multiple times, thereby returning the filter and the brush to the initial position. It is possible to avoid the tooth gap or non-repositioning situation between and facilitates the subsequent cleaning of the filter, further improving the efficiency of filter cleaning.
