Specifically, the controller obtains the indoor temperature of the area where the air conditioner indoor unit is located and the slot temperature of the first slot 1011 through the temperature acquisition component, if the slot temperature of the first slot 1011 and the indoor temperature have a temperature difference, it is indicated that the medium in the first slot 1011 is changed at this time, and condensed water ponding exists in the first slot 1011, so that it is presumed that the filter screen 103 on the second slot 1012 is blocked by the filtered impurities, and the operation condition of the cleaning mode is satisfied. The controller controls the air conditioner to operate in a cleaning mode to clean the filter screen 103, an opening instruction is generated and sent to the blowing component 105, the blowing component 105 receives the instruction to open and blow air to the filter screen 103, impurities on the filter screen 103 are blown into the first groove 1011, the filter screen 103 is restored to be conducted again, and condensed water is discharged from the drain component 104 from the filter screen 103 through the second groove 1012.

According to the air conditioner indoor unit in the embodiment, the controller is used for acquiring the indoor temperature of the area where the air conditioner indoor unit is located and the tank temperature of the first tank position in the water receiving assembly, the tank position temperature is compared with the indoor temperature, and because the temperature of condensed water generated by the air conditioner indoor unit in the operation process is lower than the indoor temperature of the area where the air conditioner indoor unit is located, if a temperature difference exists between the tank position temperature and the indoor temperature, it is indicated that the condensed water generated by the air conditioner indoor unit in the first tank position exists, namely, the filter screen arranged above the second tank position is blocked, the condensed water cannot flow out of the air conditioner indoor unit from the second tank position directly through the drainage assembly, but flows into the first tank position, at the moment, the air conditioner operation cleaning mode is controlled, the air blowing assembly is started to blow air into the filter screen, impurities obtained by filtering the condensed water on the filter screen are blown into the first tank position, the filter screen is ensured to be clean, the phenomenon that the second tank position accumulates in the second tank position to block the drainage assembly, the drain route is kept smooth, and the occurrence rate of faults of the air conditioner indoor unit caused by the continuous overflow of the condensed water is effectively reduced.

In one embodiment, the air conditioner indoor unit further comprises a water filtering assembly, wherein the water filtering assembly is arranged on the partition plate and comprises a water filtering hole good water filtering switch. The water filtering switch is electrically connected with the controller and used for opening or closing the water filtering holes.

As shown in fig. 2, the drainage hole is disposed below the partition board, and is used for separating the accumulated water of the condensed water in the first tank position from the impurities received in the first tank position, so that the condensed water flows into the second tank position through the drainage hole, and is discharged out of the air conditioner indoor unit through the drainage component.

Specifically, when the air conditioner operates in the cleaning mode, the condition that condensed water is accumulated in the first groove position at the moment is indicated, the controller generates a water filtering hole opening instruction, and the opening of the water filtering hole is controlled by controlling the opening of the water filtering switch. The condensed water accumulated in the first slot position flows into the second slot position through the water filtering hole, and is discharged out of the air conditioner indoor unit through the water discharging assembly connected with the second slot position, and impurities received in the first slot position are still filtered out and stored in the first slot position to wait for subsequent cleaning.

In one embodiment, as shown in fig. 5, an air conditioner cleaning control method is provided, which may be applied to an air conditioner indoor unit as shown in fig. 1. The method comprises the following steps:

Step 502, acquiring the indoor temperature of an area where an air conditioner indoor unit is located and the slot position temperature of a first slot position in a water receiving assembly; the water receiving assembly comprises a water receiving tank, a partition plate and a filter screen; the partition plate divides the water receiving tank into a first tank position and a second tank position; the second slot is connected with the drainage component, and the filter screen is arranged above the second slot.

Step 504, the slot temperature is compared with the room temperature.

The controller can determine whether the current filter screen is blocked or not by comparing the acquired slot temperature of the first slot with the indoor temperature of the area where the air conditioner is located.

Specifically, when the air conditioner is in operation, if the filter screen on the second slot is not blocked by the residual condensed water impurities after being filtered, the condensed water generated by the air conditioner can continue to be filtered by the filter screen and flow through the second slot, and is discharged outdoors from the drainage component connected with the second slot, and the medium in the first slot is air instead of condensed water ponding. At this time, the temperature of the slot position acquired by the first temperature sensor should be consistent with the indoor temperature of the area where the current air conditioner indoor unit is located. If the two are inconsistent, the filter screen above the second slot position can be judged to be blocked, the condensed water cannot flow into the second slot position from the filter screen, but flows into the first slot position adjacent to the second slot position from the blocked filter screen, condensed water ponding is formed in the first slot position, and the temperature of the slot position collected by the first temperature sensor becomes the temperature of the condensed water, so that the temperature difference exists between the temperature of the condensed water and the indoor temperature of the area where the current air conditioner is located. And a controller.

The cleaning mode is an operation mode in which a designer is newly added for self-cleaning of the air conditioner, and when the air conditioner operates in the cleaning mode, the controller controls the air blowing component of the air conditioner inner machine to blow air to the filter screen, and residual condensed water impurities on the filter screen are blown into the first groove.

The air conditioner is controlled to enter the cleaning mode by determining that the air conditioner meets the cleaning mode operation condition when the controller determines that the temperature difference exists between the temperature of the tank and the indoor temperature.

Specifically, if the controller compares the temperature of the tank position with the indoor temperature, and then determines that the temperature difference exists between the temperature of the tank position and the indoor temperature, the filter screen on the second tank position is blocked by residual impurities of filtered condensate water, an air conditioner operation cleaning mode needs to be controlled, the filter screen is cleaned, a drainage channel from the filter screen to the second tank position to the drainage component is dredged, and the condition that the condensate water overflows and leaks to cause the failure of an air conditioner indoor unit is avoided. The controller controls the air conditioner to operate in a cleaning mode, the air blowing component is started to blow air to the filter screen, residual impurities on the filter screen are blown into a first groove position arranged in the air blowing direction of the air blowing component, and the filter screen is automatically cleaned.

According to the air conditioner cleaning control method, the indoor temperature of the area where the air conditioner is located and the tank temperature of the first tank position in the water receiving assembly are obtained, the tank temperature is compared with the indoor temperature, and because the temperature of condensed water generated by the air conditioner is lower than the indoor temperature of the area where the air conditioner is located when the air conditioner is operated, if a temperature difference exists between the tank temperature and the indoor temperature, the fact that the condensed water generated by the air conditioner is in the first tank position is indicated to exist, namely, a filter screen arranged above the second tank position is dirty and blocked, the condensed water cannot flow out of the air conditioner from the second tank position directly through the water draining assembly, but flows into the first tank position, at the moment, the air conditioner operation cleaning mode is controlled, the air blowing assembly is started to blow air to the filter screen, impurities obtained by filtering the condensed water on the filter screen are blown into the first tank position, the cleaning of the filter screen is guaranteed, the drainage route of the second tank position and the water draining assembly is kept smooth, and the occurrence rate of air conditioner faults caused by condensate water leakage is effectively reduced.

In one embodiment, the air conditioner cleaning control method further includes: if the temperature of the tank position and the indoor temperature meet the cleaning mode starting condition, a water filtering switch of the water filtering component is controlled to be started, the water filtering component is arranged on the partition plate, and the water filtering component comprises a water filtering hole and the water filtering switch.

The water filtering component is used for filtering the condensed water accumulated water in the first groove. The drainage assembly is arranged on the partition board, the drainage hole of the drainage assembly is arranged below the partition board, the first groove position and the second groove position can be communicated by opening the drainage hole, so that condensed water accumulated in the first groove position flows into the second groove position through the drainage hole, and the condensed water accumulated in the first groove position is discharged from the air conditioner through the drainage assembly connected below the second groove position.

When the air conditioner operates in a cleaning mode, the condensed water ponding is stored in the first groove, residual impurities blown in from the filter screen by the blowing component are also received, if the water in the first groove is directly discharged through the drainage component, the residual impurities in the first groove still block the drainage component to cause the overflow and leakage of the condensed water, so that when the condensed water ponding in the first groove is discharged, the condensed water ponding in the first groove is required to be filtered by the water filtering component, the impurities are continuously stored in the first groove, the filtered condensed water can flow into the conducted second groove, and the condensed water is discharged from the air conditioner through the drainage component from the second groove.

Specifically, when the air conditioner is in a cleaning mode, the controller also controls the water filtering switch of the water filtering assembly on the partition plate to be opened, so that the water filtering hole of the water filtering assembly is opened, the first groove position and the second groove position are communicated, condensed water accumulated in the first groove position flows into the second groove position after being filtered by the water filtering hole, and then is discharged from the air conditioner indoor unit through the water discharging assembly connected with the bottom of the second groove position.

According to the method, the water filtering assembly is arranged on the partition plate between the first groove position and the second groove position, and the situation that the condensed water overflows and leaks due to the fact that the water filtering assembly is blocked when residual garbage stored in the first groove position flows through the water draining assembly can be effectively avoided during discharging through filtering accumulated water of the condensed water in the first groove position to be discharged.

In one embodiment, as shown in fig. 6, the air conditioner cleaning control method further includes the steps of:

step 602, after the air conditioner operation cleaning mode is controlled to reach a preset time, the air blowing component is turned off.

The preset duration is a single operation duration of the cleaning mode preset according to the actual use condition of the air conditioner. Specifically, in order to avoid the reduction of service life caused by long-time opening of the air blowing component, the controller can close the air blowing component after controlling the air conditioner to operate in a cleaning mode for a preset period of time, so that subsequent detection is performed.

Step 604, obtaining the current slot position temperature of the first slot position in real time, and comparing the current slot position temperature with the indoor temperature.

Specifically, after the controller controls the air blowing component to be closed, the air blowing component cleans the filter screen once at the moment, the controller obtains the current slot position temperature of the first slot position after single cleaning, compares the current slot position temperature with the current indoor temperature, and determines whether the filter screen needs to be cleaned continuously.

Step 606, if the current temperature of the tank and the indoor temperature do not meet the operation condition of the cleaning mode, the air conditioner is controlled to switch to the normal operation mode.

Specifically, if there is no temperature difference between the current tank temperature and the indoor temperature, it is indicated that the current tank temperature and the indoor temperature do not meet the operation condition of the cleaning mode, i.e. the residual impurities above the filter screen are cleaned by the air blowing component, and the filter screen is turned on again. At this time, the controller controls the air conditioner to be switched into a normal operation mode.

If the current temperature of the tank and the indoor temperature meet the cleaning mode operation condition, the step 608 returns to the step of controlling the air conditioner to operate in the cleaning mode.

Specifically, if there is a temperature difference between the current tank temperature and the indoor temperature, it is indicated that the current tank temperature and the indoor temperature meet the cleaning mode operation condition, that is, the residual impurities above the filter screen are not cleaned completely in the current cleaning mode operation process, and the filter screen is not conducted. At this time, the controller returns to the step of controlling the air conditioner to operate in the cleaning mode, and the judgment is circularly carried out until the current tank temperature and the indoor temperature do not meet the operating condition of the cleaning mode.

In this embodiment, through prescribing cleaning mode single operation duration, can effectively promote the life of subassembly of blowing, under the prerequisite, the circulation judges whether current air conditioner satisfies cleaning mode operation condition, ensures the effect of air conditioner self-cleaning, avoids leading to the comdenstion water to overflow and leak and cause the emergence of air conditioner internal-unit trouble because of the filter screen is clean not in place continue operation.

Further, in one embodiment, after the cleaning mode of continuously controlling the air conditioner to operate reaches the preset times, if the current slot temperature and the indoor temperature still meet the cleaning mode operation condition, generating alarm information; and sending alarm information to an alarm assembly, wherein the alarm information is used for prompting a user to clear the first slot position.

The preset times are determined by a designer according to the operation parameters and the performance parameters of the blowing assembly, and the times of cleaning completion are judged. Taking 5 times of preset times as an example, if the preset times are 5 times, the fact that the air blowing assembly only needs to continuously run for 5 times under the running parameters and the performance parameters of the air blowing assembly can blow all impurities remained on the filter screen into the first groove to finish the automatic cleaning of the filter screen is indicated.

Specifically, if the continuous control air conditioner operation cleaning mode reaches the preset times, the current tank temperature and the indoor temperature obtained in real time still meet the cleaning mode operation conditions, which indicates that condensed water accumulated in the first tank is always present at the moment, the reason for the situation is likely that the impurity storage amount in the first tank is too large, so that the water filtering holes on the partition plate are blocked by impurities, the condensed water accumulated in the first tank cannot flow into the second tank, and flows out through the drainage component. Therefore, the temperature of the condensed water collected by the first temperature sensor always has a temperature difference with the indoor temperature, and the operation condition of the cleaning mode is met. At the moment, the device can only give an alarm to a user, prompts the user to manually clear the first groove, and avoids the occurrence of faults of the air conditioner indoor unit caused by overflow and leakage of condensed water.

In this embodiment, through generating alarm information and broadcasting, can effectively remind the user in time to clear up the impurity of storing in the first trench, avoid because first trench impurity is too much, lead to the drainage hole to block up to cause the comdenstion water to overflow and leak the condition that damages the air conditioner internal unit to produce.

In one embodiment, the cleaning mode operating conditions further comprise: the temperature difference between the temperature of the tank and the indoor temperature is larger than a preset difference threshold.

The preset difference threshold is designed by a designer to avoid erroneous judgment of the operation condition of the cleaning mode due to error or interference of environmental factors, and it is understood that the preset difference threshold is set according to the actual operation parameters and the actual operation environment of the air conditioner, and specific values are not limited in this application.

Specifically, in order to avoid the interference of the acquisition error of the temperature sensor or other environmental factors when the controller judges whether the cleaning mode operation condition is satisfied, a difference threshold is preset for accurately judging whether the current air conditioner should operate the cleaning mode when the designer designs the cleaning mode operation condition. When the controller compares the temperature of the first tank with the indoor temperature, when the difference value exists between the temperature of the first tank and the indoor temperature, the difference value between the temperature of the first tank and the indoor temperature is further compared with a preset difference value threshold, if the difference value exceeds the preset difference value threshold, the difference value between the temperature of the first tank and the indoor temperature is considered to be caused by the difference between the temperature of the first tank and the temperature of the second tank and the temperature of the third tank is not caused by the interference of collecting errors or other environmental factors, but is caused by the difference between the temperature of condensed water and the temperature of the current indoor temperature, the condition that the air conditioner meets the operation condition of the cleaning mode is determined, and the operation cleaning mode of the air conditioner is controlled.

In the embodiment, the judgment step of adding the preset difference threshold value in the operation condition of the cleaning mode effectively avoids the situation of inaccurate judgment caused by acquisition errors of the temperature sensor or interference of other environmental factors, and improves the accuracy of the controller in judging and controlling the operation cleaning mode of the air conditioner.

In one embodiment, as shown in fig. 7, before controlling the air conditioner operation cleaning mode, the air conditioner cleaning control method further includes the steps of:

step 702, acquiring the current starting operation time and the previous closing operation time of the air conditioner.

The current starting operation time of the air conditioner refers to the starting time of the air conditioner when the air conditioner operates at the position; the last closing operation time of the air conditioner refers to the closing time of the air conditioner when the air conditioner operates last time.

Specifically, the controller acquires the on time of the air conditioner at this time of operation and the off time of the air conditioner at the previous time of operation before controlling the air conditioner to operate in the cleaning mode.

Step 704, the current start-up run time is compared to the previous shut-down run time.

Specifically, the controller compares the on time of the air conditioner when the air conditioner is operated at this time with the off time of the air conditioner when the air conditioner is operated at the previous time, and determines the time interval from the previous operation of the air conditioner to the operation of the air conditioner at this time.

Step 706, if the time interval between the current start-up running time and the previous shut-down running time is greater than the preset time interval, generating alarm information, and sending the alarm information to the alarm assembly, where the alarm information is used to prompt the user to manually clean the first slot.

Specifically, when the controller determines that the time interval between the current running time and the previous starting running time is greater than the preset time interval, the air conditioner is not started for a long time, and under the condition that the air conditioner is not started for a long time, the temperature in the tank of the first tank and the indoor temperature of the area where the air conditioner is positioned still meet the running condition of the cleaning mode, and the condensed water ponding which cannot be discharged exists in the first tank at the moment, namely, the water filtering holes on the partition plate are blocked by excessive impurities stored in the first tank. The controller generates alarm information, sends the alarm information to the alarm assembly, and prompts a user to manually clean excessive impurities in the first groove, so that the water filtering holes are unblocked.

In this embodiment, by comparing the on time of the air conditioner during this operation with the off time of the air conditioner during the previous operation, when it is determined that the time interval between the current operation time and the previous start operation time is greater than the preset time interval, alarm information is generated to prompt the user to manually clean the first slot, so that the situation that the air conditioner internal unit is damaged due to overflow of condensed water caused by blockage of the drainage hole due to excessive impurities of the first slot can be effectively avoided.

Further, in one embodiment, before generating the alarm information, the method further includes: generating a water filtering hole opening instruction, controlling the water filtering hole to be opened, acquiring the current slot position temperature of the first slot position and the indoor temperature of the area where the air conditioner is located again when the water filtering hole opening time reaches the preset opening time, and generating alarm information if the current slot position temperature and the indoor temperature meet the cleaning mode operation condition; and if the current slot temperature and the indoor temperature do not meet the cleaning mode operation condition, controlling the air conditioner to switch to the normal operation mode.

In one embodiment, as shown in fig. 8, there is provided an air conditioner cleaning control method, which can be applied to the air conditioner indoor unit shown in fig. 4, the method comprising the steps of:

the controller obtains the slot position temperature of the first slot position through the temperature sensor arranged in the first slot position, obtains the indoor temperature of the area where the air conditioner is located at the same time, compares the slot position temperature with the indoor temperature, and controls the air conditioner to operate in a normal operation mode if no temperature difference exists between the slot position temperature and the indoor temperature or the temperature difference exists between the slot position temperature and the indoor temperature but the temperature difference is smaller than a preset temperature difference threshold value.

If the temperature difference exists between the groove temperature and the indoor temperature and is larger than the preset temperature difference threshold value, determining that the current air conditioner meets the operation condition of the cleaning mode. The controller obtains the current starting running time and the previous closing running time of the air conditioner, compares the current starting running time with the previous closing running time, generates alarm information if the time interval of the current starting running time and the previous closing running time is larger than the preset time interval, sends the alarm information to the alarm assembly, and prompts a user to manually clean the first slot position.

And if the time interval of the two is smaller than the preset time interval, controlling the air conditioner to operate in a cleaning mode. Specifically, the controller generates a fan start instruction, sends the fan start instruction to the fan switch of the blowing assembly, controls the fan switch to be started, and blows air to the filter screen arranged on the second slot position, so that residual impurities on the filter screen after the condensed water is filtered are blown into the first slot position. Meanwhile, a water filtering hole opening command is generated and sent to a water filtering switch of the water filtering assembly, the water filtering switch is controlled to be opened, condensed water accumulated in the first groove position flows into the second groove position after being filtered by the water filtering hole, and is discharged from the air conditioner indoor unit through a water discharging assembly connected with the bottom of the second groove position.

When the controller controls the air conditioner to operate in the cleaning mode for a preset time period, a fan closing instruction is generated and sent to a fan switch of the blowing assembly, and the fan switch is controlled to be closed. And acquiring the current tank position temperature of the first tank position in real time, comparing the current tank position temperature with the current indoor temperature, and controlling the air conditioner to run the cleaning mode again if the current tank position temperature and the current indoor temperature have a temperature difference which is larger than a preset temperature difference threshold value, wherein the process is circularly executed until the current tank position temperature and the current indoor temperature have no temperature difference or have a temperature difference which is smaller than the preset temperature difference threshold value.

After the controller controls the air conditioner to continuously run the cleaning mode for 5 times, the current tank position temperature of the first tank position is obtained in real time, the current tank position temperature is compared with the current indoor temperature, if the current tank position temperature and the current indoor temperature have a temperature difference, and the temperature difference is larger than a preset temperature difference threshold value, alarm information is generated, the alarm information is sent to the alarm assembly, and a user is prompted to manually clean the first tank position. If the temperature of the current tank position and the current indoor temperature have no temperature difference or have a temperature difference but are smaller than a preset temperature difference threshold value, the air conditioner is controlled to be switched into a normal operation mode.
