The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Based on the background art pointed out, the existing rubber ball online cleaning device for cleaning the heat exchange pipeline of the condenser is independently controlled, and the control is troublesome. The invention provides a control method for a central air conditioner and the central air conditioner, and aims to directly bring a rubber ball online cleaning device into a control system of the central air conditioner, realize centralized control and be more convenient to control.

The central air conditioner comprises a compressor, a condenser heat exchange pipeline, a rubber ball online cleaning device and a controller, wherein the rubber ball online cleaning device is communicated with the condenser heat exchange pipeline and is in communication connection with the controller, and the controller can control the rubber ball online cleaning device to run and stop.

Through the arrangement, the rubber ball online cleaning device is directly brought into the control system of the central air conditioner, the centralized control is realized, the control is more convenient, and the rubber ball online cleaning device is not required to be provided with an independent control box.

Referring to fig. 1, fig. 1 is a schematic structural view of a rubber ball online cleaning device according to the present invention.

Illustratively, as shown in fig. 1, the glue ball online cleaning device of the present invention comprises a glue ball (not shown), a service chamber 1, a ball collection chamber 2, a filter pipe 3, and a motor 4, wherein the glue ball can move back and forth between the service chamber 1 and the ball collection chamber 2 when a cleaning operation is performed. Wherein, service cavity 1 is located and receives ball cavity 2 tops to receive ball inner chamber 2 and service cavity 1 can communicate with the both ends of condenser heat transfer pipeline respectively. Meanwhile, the filter pipe 3 is arranged between the ball receiving cavity 2 and the ball serving cavity 1, the motor 4 is electrically connected with one end of the filter pipe 3, and the motor 4 can drive the internal structure of the filter pipe 3 to rotate so as to control the on-off between the ball serving cavity 1 and the ball receiving cavity 2.

When the rubber ball on-line cleaning device is in a non-working state, the ball serving cavity 1 and the ball receiving cavity 2 are in a disconnected state, the rubber ball is positioned in the ball serving cavity 1 and cannot move, when the rubber ball online cleaning device needs to perform cleaning operation, the motor 4 drives the internal structure of the filter pipe 3 to rotate reversely by 90 degrees, so as to communicate the ball serving cavity 1 with the ball receiving cavity 2, at the moment, the rubber balls can enter the condenser heat exchange pipeline from the ball serving cavity 1, then moves along the heat exchange pipeline of the condenser and enters the ball receiving chamber 2, then the motor 4 drives the internal structure of the filter tube 3 to rotate 180 degrees in the positive direction, the rubber balls enter the heat exchange pipeline of the condenser from the ball receiving chamber 2, then moving along a heat exchange pipeline of the condenser, returning to the ball serving chamber 1 to finish primary cleaning, wherein the flowing rubber balls can discharge impurities in the heat exchange pipe of the condenser out of the heat exchange pipe, so that the cleaning effect is realized; after the cleaning operation is finished, the internal structure of the motor 4 driving the filter pipe 3 is reversed by 90 degrees, the ball receiving cavity 2 and the ball serving cavity 1 are disconnected, the rubber balls are stopped in the ball serving cavity 1, and the next cleaning operation is waited.

It should be noted that, a first pipeline (not shown in the figure) and a second pipeline (not shown in the figure) are arranged at the left and right side ends of the service chamber 1, and the first pipeline and the second pipeline are both communicated with the service chamber 1, correspondingly, a third pipeline (not shown in the figure) and a fourth pipeline (not shown in the figure) are arranged at the left and right side ends of the ball receiving chamber 2, and the third pipeline and the fourth pipeline are both communicated with the ball receiving chamber 2, and at the same time, the first pipeline and the third pipeline are connected through one end of the filter pipe 3; the second pipeline and the fourth pipeline are both connected with the other end of the filter pipe 3. When the rubber ball on-line cleaning device is in a working state, the first pipeline and the third pipeline form a passage, and the second pipeline and the fourth pipeline form a passage, namely, the rubber ball can circularly move between the ball serving chamber 1 and the ball receiving chamber 2. When the rubber ball online cleaning device is in a non-working state, the first pipeline and the third pipeline are disconnected, the second pipeline and the fourth pipeline are disconnected, and the rubber ball stops moving in a reciprocating mode.

Based on the central air conditioner, the present invention further provides a control method for a central air conditioner, as shown in fig. 2, the control method of the present invention includes: after receiving a cleaning instruction, judging whether a compressor of the central air conditioner is in a closed state; and if the judgment result is yes, the rubber ball online cleaning device is operated to clean the heat exchange pipeline of the condenser.

The cleaning command may be triggered automatically, for example, a timing cleaning mode is adopted, a preset time is set, and the cleaning command is triggered once every preset time, or the cleaning command may be sent by a user, that is, a manual cleaning mode is adopted, and the user sends the cleaning command.

Preferably, the central air conditioner of the present invention includes a manual washing mode and a timed washing mode. Further preferably, the timed cleaning mode comprises a standard cleaning mode and a high-frequency cleaning mode, wherein the time interval of the high-frequency cleaning mode is smaller than the time interval of the standard cleaning mode. Illustratively, the wash command is automatically triggered every 120 minutes in the standard wash mode and every 40 minutes in the high frequency wash mode. The user may select either the standard wash mode or the high frequency wash mode depending on the field conditions.

After the controller receives a cleaning instruction, the rubber ball online cleaning device is not operated firstly, but the current state of the compressor is obtained firstly, whether the compressor is in a closed state is judged, if the judgment result is yes, namely the compressor is in the closed state, under the condition, the rubber ball online cleaning device can be directly operated to clean the heat exchange pipeline of the condenser.

It should be noted that, in the case that the determination result is "no", that is, in the case that the compressor is in the operating state, the compressor may be directly turned off first, and then the rubber ball online cleaning device is operated, or information on whether to turn off the compressor may be sent to the user first; the flexible adjustment and change of the compressor after receiving the confirmation information of the user and then the operation of the rubber ball on-line cleaning device are not deviated from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

Preferably, as shown in fig. 2, if the judgment result is "no", the central air conditioner is caused to transmit information whether to turn off the compressor to the user; after receiving the information that the user confirms to close the compressor, the compressor is closed firstly, and then the rubber ball online cleaning device is operated.

After receiving a cleaning instruction, if the compressor is in an operating state, confirming whether the compressor is closed or not to a user, if the user confirms that the compressor can be closed, closing the compressor, and then operating the rubber ball online cleaning device to clean the heat exchange pipeline of the condenser.

It should be noted that, if the user does not agree to turn off the compressor, the instruction for cleaning this time is ignored, and in addition, if the confirmation information of the user is not received within the preset time, the instruction for cleaning this time is also ignored.

Preferably, as shown in fig. 3, the control method of the present invention further includes: acquiring the total operation times of the rubber ball online cleaning device; and selectively enabling the central air conditioner to send out prompt information for replacing the rubber balls according to the total running times.

Through such setting, can monitor the life of glueballs effectively, when needs are changed glueballs, can remind the user in time to change glueballs to guarantee glueballs online cleaning device's cleaning performance.

Illustratively, a counter is arranged in the controller and is recorded as a first counter, the total number of times of operation of the rubber ball online cleaning device is recorded through the first counter, the numerical value of the first counter is increased by 1 when the rubber ball online cleaning device operates once, and the controller can judge whether the central air conditioner needs to send out prompt information for replacing the rubber ball according to the numerical value recorded by the first counter. And after the user replaces the new rubber ball, the first counter is cleared and starts counting again.

It should be noted that, the display panel of the central air conditioner can display the total number of times of the operation of the rubber ball online cleaning device, so as to be convenient for the user to view.

It should be noted that after the total number of operations of the rubber ball online cleaning device is obtained, the total number of operations of the rubber ball online cleaning device may be directly compared with the limit number of operations to determine whether to enable the central air conditioner to send out the prompt information for replacing the rubber ball, or the total number of operations of the rubber ball online cleaning device may be compared with a preset number (smaller than the limit number of operations) to determine whether to enable the central air conditioner to send out the prompt information for replacing the rubber ball, or a difference between the limit number of operations and the total number of operations may be calculated first, and then whether to enable the central air conditioner to send out the prompt information for replacing the rubber ball is determined according to the difference, and so on.

Preferably, as shown in fig. 3, the step of selectively enabling the central air conditioner to send out the prompt message for replacing the rubber ball according to the total number of running times specifically includes: calculating the difference between the limit operation times and the total operation times; comparing the difference value with a first preset value; and selectively enabling the central air conditioner to send out prompt information for replacing the rubber ball according to the comparison result.

The controller is internally pre-stored with limit operation times and a first preset value, after the total operation times of the rubber ball online cleaning device are obtained, a difference value between the limit operation times and the total operation times is calculated, the difference value is equal to the limit operation times-the total operation times, then the difference value is compared with the first preset value, the sizes of the limit operation times and the total operation times are judged, and whether the central air conditioner needs to send prompt information for replacing the rubber balls is judged according to a comparison result.

It should be noted that, in practical applications, a person skilled in the art may flexibly set the specific values of the limit operation times and the first preset value according to experiments or experience.

Preferably, the step of selectively causing the central air conditioner to send out the prompt message for replacing the rubber ball according to the comparison result specifically includes: if the difference is smaller than the first preset value, the central air conditioner sends out prompt information for replacing the rubber ball.

Illustratively, the limit operation time is 1500, the first preset value is 100, the difference is 1500-the total operation time, when the difference is less than 100, it indicates that the service life of the rubber ball is relatively close to the use limit, the rubber ball needs to be replaced as soon as possible, otherwise the cleaning effect of the rubber ball online cleaning device is affected, and in this case, the central air conditioner sends out a prompt message for replacing the rubber ball to remind a user to replace the rubber ball as soon as possible.

It should be noted that, when the difference between the limit operation times and the total operation times is smaller than a first preset value, the display panel of the central air conditioner can display information for prompting the replacement of the rubber ball by alarming and rolling, and the total operation times is cleared and the display panel normally operates until the rubber ball is replaced; alternatively, the central air conditioner may be caused to sound an alarm intermittently, or the central air conditioner may be caused to send a message to a client terminal, etc., and the adjustment and change of the specific form of the prompting message for replacing the rubber ball are not departing from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

It should be noted that if the difference is not less than the first preset value, the central air conditioner does not send out a prompt message for replacing the rubber ball.

Preferably, the control method of the present invention further comprises: comparing the difference value with a second preset value under the condition that the difference value is smaller than the first preset value; selectively enabling the central air conditioner to send out prompt information of the faults of the rubber ball online cleaning device according to the comparison result; and the second preset value is smaller than the first preset value.

The controller is also pre-stored with a second preset value, under the condition that the difference value between the limit operation times and the total operation times is smaller than the first preset value, the service life of the rubber ball is relatively close to the use limit, if a user does not timely replace the rubber ball, the difference value is compared with the second preset value so as to judge that the service life of the rubber ball reaches or is very close to the use limit, and the central air conditioner is selectively enabled to send out prompt information of the failure of the rubber ball online cleaning device according to the judgment result.

Through such setting, when the glueballs are very close or reach the use limit, the user can be reminded in time that the online cleaning device for the glueballs cannot perform cleaning work, and the glueballs need to be replaced immediately.

It should be noted that, in practical applications, a person skilled in the art may flexibly set the specific value of the second preset value according to experiments or experience, and for example, the value of the second preset value may be set to any value between 0 and 10.

Preferably, the step of selectively enabling the central air conditioner to send out the prompt message of the fault of the rubber ball online cleaning device according to the comparison result specifically comprises the following steps: if the difference is smaller than or equal to the second preset value, the central air conditioner sends out prompt information of the failure of the rubber ball on-line cleaning device.

When the difference value between the limit operation times and the total operation times is smaller than or equal to a second preset value, the rubber ball reaches or is very close to the use limit, and under the condition, the cleaning effect of the rubber ball online cleaning device is very poor, so that the central air conditioner sends out fault prompt information of the rubber ball online cleaning device.

It should be noted that when the difference between the limit operation times and the total operation times is greater than the second preset value, it indicates that the rubber ball has not reached the use limit, and the rubber ball online cleaning device can also achieve a certain cleaning effect, and in this case, the central air conditioner does not send out the fault prompt information of the rubber ball online cleaning device.

Preferably, in the case that the difference between the limit operation times and the total operation times is less than or equal to the second preset value, the control method of the present invention further comprises: and when a cleaning instruction is received, the rubber ball online cleaning device is not operated.

When the difference value between the limit operation times and the total operation times is smaller than or equal to a second preset value, the fact that the rubber ball has no cleaning effect or the cleaning effect is very poor is indicated.

Preferably, the control method of the present invention further comprises: in the operation process of the rubber ball online cleaning device, the reciprocating times of the rubber balls in the heat exchange pipeline of the condenser are obtained; and when the reciprocating times reach the set times, stopping the operation of the rubber ball online cleaning device.

Illustratively, the set number of times is 5, another counter is further arranged in the controller and is marked as a second counter, the second counter is used for recording the reciprocating times of the rubber ball in the heat exchange pipeline of the condenser in each cleaning operation process, when the cleaning operation is not executed, a ball receiving chamber and a ball sending chamber of the rubber ball online cleaning device are in a disconnected state, when the cleaning operation is started, a motor is firstly rotated reversely by 90 degrees to communicate the ball receiving chamber with the ball sending chamber, the rubber ball enters the heat exchange pipeline of the condenser from the ball sending chamber, then flows along the heat exchange pipeline of the condenser and enters the ball receiving chamber, then the motor is rotated forwardly by 180 degrees, the rubber ball enters the heat exchange pipeline of the condenser from the ball receiving chamber, then flows along the heat exchange pipeline of the condenser and enters the ball sending chamber, the rubber ball completes one reciprocating movement in the heat exchange pipeline of the condenser, the numerical value of the second counter is added by 1, and when the numerical value of the second counter reaches 5, finishing the cleaning operation, and stopping the operation of the rubber ball online cleaning device.

It should be noted that the specific value of the set number is not limited to 5, for example, the set number may be set to 1, 3, 8, 10, etc., and those skilled in the art may flexibly set the specific value of the set number in practical applications according to experiments or experience.

So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
