Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention and are not to be construed as limiting the present invention.

A control method of an air conditioner according to an embodiment of the present invention is described below with reference to fig. 1 to 21.

According to the control method of the air conditioner, the air conditioner comprises the water receiving assembly and the water pump, and the water pump is used for pumping the condensed water in the water receiving assembly. The water pump is a machine for conveying liquid or pressurizing liquid, and transfers the mechanical energy of prime mover or other external energy to liquid to increase the energy of liquid. A positive displacement pump uses the change in the volume of its working chamber to transfer energy. Vane pumps transfer energy by the interaction of rotating vanes with water and are available in the types of centrifugal pumps, axial flow pumps, mixed flow pumps, and the like.

The control method of the air conditioner comprises the following steps:

s100, determining the running rotating speed of the water pump in the running process of the air conditioner, and further, the air conditioner can be provided with a determining module which is used for detecting the running rotating speed of the water pump in the working process of the air conditioner.

S200, the water pump and the air conditioner are controlled according to the running rotating speed of the water pump, so that condensed water in the water receiving assembly can be prevented from overflowing, further, the air conditioner can be provided with a control module, the control module can control the water pump and the air conditioner according to the running rotating speed of the water pump, and the condensed water is prevented from overflowing from the water receiving assembly.

The maximum design output power of the water pump motor is constant, and according to a formula of P = T omega, the rotating speed omega of the water pump motor is inversely proportional to the torque T under the condition that the output power of the water pump motor is constant, and an impeller of the water pump only works on air under the condition that the water pump does not contain water in the water receiving assembly. As shown in fig. 2, it is assumed that the maximum rotation speed of the water pump is 1000 rpm at the full water level (water level H1) and the rotation speed of the water pump is 2000 rpm at the minimum water level H2. Then the rotation speed of the water pump is set to be 5000 r/min when the air conditioner is started, then the determination module detects the actual rotation speed of the water pump, and if no water exists in the water receiving assembly or the water is little, the rotation speed of the water pump can be 3000 r/min or/2000 r/min. If there is some water in the water receiving assembly, the rotation speed fluctuates between 1000 and 2000. If the water pump is blocked and locked by impurities or the motor of the water pump is damaged, the rotating speed of the motor may be less than 100 revolutions or even not, and the water pump is considered to be in fault at the moment. Therefore, the water level in the water receiving assembly is shallower, the rotating speed of the water pump is larger, the water in the water receiving assembly is deeper, the rotating speed of the water pump is larger, and the rotating speed of the water pump is in direct proportion to the depth of the water level in the water receiving assembly.

Specifically, the water pump is started firstly after the air conditioner is started, the determining module detects the running rotating speed of the water pump in the working process of the air conditioner, the determining module sends the running rotating speed information of the water pump to the control module, and after the control module receives the running rotating speed information of the water pump, the control module can control the water pump and the air conditioner according to the running rotating speed value of the water pump. Specifically, when the running rotating speed value of the water pump is larger than or equal to the first rotating speed value, no water or little water exists in the water receiving assembly, the pump body does not need to pump water towards the outside of the water receiving assembly, and the control module controls the water pump to stop working and controls the air conditioner to keep running. When the running rotating speed value of the water pump is smaller than the first rotating speed value, it is indicated that part of water exists in the water receiving assembly, the pump body is required to work and pump water towards the outside of the water receiving assembly, the control module controls the water pump to continue working, and the air conditioner is controlled to keep a running state. When the running rotating speed value of the water pump is smaller than the first rotating speed value and larger than the second rotating speed value, it is indicated that part of water exists in the water receiving assembly, the control module controls the water pump to continue working, and when the running rotating speed value of the water pump is smaller than the second rotating speed value and larger than the third rotating speed value, it is indicated that water in the water receiving assembly is more or full, the control module controls the running power of the water pump to be increased, and water in the water receiving assembly is discharged in time. When the running rotating speed value of the water pump is smaller than the third rotating speed value, the situation that the water pump is blocked and locked by impurities or the water pump motor is damaged is shown, namely the water pump breaks down, the control module controls the water pump and the air conditioner to stop working, and condensate water is prevented from being continuously gathered in the water receiving assembly.

According to the air conditioner control method, the water level condition in the water receiving assembly can be determined according to the rotating speed of the water pump, so that whether the water pump and/or the air conditioner work can be controlled according to the operating rotating speed of the water pump, water in the water receiving assembly can be timely discharged out of the water receiving assembly, the condensate water in the water receiving assembly can be prevented from overflowing, indoor objects can be prevented from being soaked by the condensate water, property loss of users can be avoided, and compared with the prior art, the water level switch is not needed to be matched with the water pump to work, the water level switch is not needed to be arranged on the air conditioner, and the problem of water leakage of the air conditioner caused by failure of the water level switch can be fundamentally avoided.

Therefore, according to the control method of the air conditioner, whether the water pump and the air conditioner work or not is controlled according to the running rotating speed of the water pump, the water level switch does not need to be matched with the water pump to work, the water level switch does not need to be arranged on the air conditioner, the problem of water leakage of the air conditioner caused by failure of the water level switch can be fundamentally avoided, indoor objects can be prevented from being soaked by water, and property loss of users can be further avoided.

In some embodiments of the present invention, controlling the water pump and the air conditioner according to the operation speed of the water pump may include: the operation rotating speed of the water pump is judged, specifically, when the operation rotating speed of the water pump is greater than or equal to a first preset rotating speed (namely, a first rotating speed value), it indicates that no water exists in the water receiving assembly or the water level is at the lowest water level, the water in the water receiving assembly cannot overflow the water receiving assembly, at the moment, the control module controls the water pump to stop working, and the control module controls the air conditioner to keep an operation state. When the operation rotating speed of the water pump is smaller than a first preset rotating speed, the control module controls the water pump to continue to work and controls the air conditioner to keep in an operation state, the water pump is in an operation state at the moment, the water pump can pump out condensed water in the water receiving assembly in real time, the condensed water in the water receiving assembly can be guaranteed not to overflow the water receiving assembly, and meanwhile normal use of the air conditioner is not influenced.

In some embodiments of the present invention, when the operation rotation speed of the water pump is less than a first preset rotation speed, controlling the water pump and the air conditioner according to the operation rotation speed of the water pump may further include: when the running rotating speed of the water pump is greater than or equal to a second preset rotating speed (namely a second rotating speed value), namely the running rotating speed of the water pump is less than the first preset rotating speed and greater than or equal to the second preset rotating speed, it indicates that part of water exists in the water receiving assembly, the water pump is required to pump out the water receiving assembly, the control module controls the water pump to keep running in the current working state, and at the moment, the control module controls the water pump to continue working, so that condensed water in the water receiving assembly is guaranteed to be pumped out in time, and further condensed water overflow is avoided.

Furthermore, when the running rotating speed of the water pump is greater than or equal to a third preset rotating speed (namely, a third rotating speed value) and less than a second preset rotating speed, the situation that more condensed water in the water receiving assembly or the full water level in the water receiving assembly is indicated at the moment, the condensed water in the water receiving assembly needs to be quickly discharged, the control module controls the running power of the water pump to be increased, more condensed water in the water receiving assembly can be pumped out in unit time, the discharging rate of the condensed water pump in the water receiving assembly can be increased, therefore, the condensed water can be further prevented from overflowing the water receiving assembly, and further, the water leakage of the air conditioner can be avoided.

Furthermore, when the running rotating speed of the water pump is less than a third preset rotating speed, the phenomenon that the water pump is blocked and locked by impurities or the water pump motor is damaged is shown, namely the water pump breaks down, the water pump cannot pump out condensed water in the water receiving assembly in time, at the moment, if the air conditioner continues to work, the condensed water can continue to be gathered in the water receiving assembly, the condensed water has the risk of overflowing the water receiving assembly, therefore, the water pump and the air conditioner are controlled to stop working through the control module, and the overflow of the condensed water in the water receiving assembly can be further avoided.

In some embodiments of the present invention, when the operating speed of the water pump is greater than or equal to the third preset speed and less than the second preset speed, and the duration time is greater than or equal to the fourth preset time (for example, the fourth preset time is set to 1 minute), it is determined that the water receiving assembly is in a full water level state, that is, the water receiving assembly is full of water, and the CPU controls the air conditioner to send out a full water prompt message, so that the user knows that the water receiving assembly is full of water. And then the control module controls and improves the running power of the water pump, so that the output rate of the condensate pump in the water receiving assembly can be improved, and the condensate water can be further prevented from overflowing the water receiving assembly. However, the invention is not limited to this, and the control module can control the air conditioner to stop after the water receiving assembly is filled with water.

In some embodiments of the present invention, after controlling the water pump to stop operating, the method may further include: judging whether a water pump operation instruction is received or not, if so, controlling the water pump to start to operate, and determining the operation rotating speed of the water pump after first preset time, otherwise, controlling the water pump to start to operate when the air conditioner performs refrigeration operation, and determining the operation rotating speed of the water pump after the first preset time. Specifically, when the operation rotation speed of the water pump is greater than or equal to a first preset rotation speed, it indicates that no water exists in the water receiving assembly or the water level is at the lowest water level, water in the water receiving assembly cannot overflow the water receiving assembly, at the moment, the control module controls the water pump to stop working, then the control module judges whether a water pump operation instruction is received, if the control module receives the water pump operation instruction, the control module controls the water pump to start working, and after a first preset time (for example, the first preset time is set to be 1 minute), the determining module determines the operation rotation speed of the water pump, then the determining module transmits the operation rotation speed information of the water pump to the control module, and the control module can control the working states of the water pump and the air conditioner according to the operation rotation speed of the water pump, so that condensed water is prevented from overflowing from the water receiving assembly.

Further, when the operation rotation speed of the water pump is greater than or equal to a first preset rotation speed, it indicates that no water exists in the water receiving assembly or the water level is at the lowest water level, water in the water receiving assembly cannot overflow the water receiving assembly, at the moment, the control module controls the water pump to stop working, then the control module judges whether a water pump operation instruction is received, if the control module does not receive the water pump operation instruction, a Central Processing Unit (CPU) of the air conditioner detects whether the air conditioner starts a refrigeration operation mode, if the air conditioner starts the refrigeration operation mode, the CPU sends a control instruction to the control module, then the control module controls the water pump to start working, and after a first preset time, the determination module determines the operation rotation speed of the water pump, then the determination module transmits the operation rotation speed information of the water pump to the control module, and the control module can control the working states of the water pump and the air conditioner according to the operation rotation speed of the water pump, so as to prevent condensate water from overflowing from the water receiving assembly.

In some embodiments of the invention, when the water pump operation instruction is not received and the air conditioner does not start cooling operation, whether the air conditioner is stopped or not is judged, wherein if yes, namely the air conditioner is stopped, the water pump is controlled to be in a stop working state, if not, namely the air conditioner is not stopped, the control module controls the water pump to start operation when the operation time of the air conditioner is greater than or equal to a second preset time (for example, the second preset time is 1 minute), and the determination module determines the operation rotating speed of the water pump after the first preset time.

Specifically, when the operation rotating speed of the water pump is greater than or equal to a first preset rotating speed, the control module controls the water pump to stop working at the moment, then the control module judges whether a water pump operation instruction is received or not, if the control module does not receive the water pump operation instruction and the air conditioner does not start a refrigeration mode, then the CPU detects whether the air conditioner stops or not, if the air conditioner is in a stop state, the control module controls the water pump to start working, when the operation time of the air conditioner is greater than or equal to a second preset time, the determination module determines the operation rotating speed of the water pump after the water pump is started for the first preset time, then the determination module transmits the operation rotating speed information of the water pump to the control module, and the control module can control the working states of the water pump and the air conditioner according to the operation rotating speed of the water pump to prevent condensed water from overflowing from the water receiving assembly.

In some embodiments of the present invention, when the operation rotation speed of the water pump is less than the third preset rotation speed and continues for a third preset time, if the control module does not receive a water pump stop instruction, the determination module continues to determine whether the operation rotation speed of the water pump is less than the third preset rotation speed, wherein if so, that is, the determination module determines that the operation rotation speed of the water pump is less than the third preset rotation speed, it is determined that the water pump fails, and the water pump failure counter counts the number of failures, and the control module controls the water pump to stop operating, and when the number of failures is greater than or equal to the first preset number (the first preset number may be set to 3), the control module controls the air conditioner to stop operating, so that the air conditioner can be prevented from continuously generating condensed water during refrigeration, and the condensed water can be effectively prevented from overflowing the water receiving assembly.

Further, the air conditioner may further include a display unit, for example: the display unit is a display screen, after the water pump is determined to have a fault, the CPU controls the display unit to display a water pump fault code, and/or the CPU controls the control module to control and light an indicator lamp for indicating the water pump fault.

The control method of the present application may estimate the water level in the water receiving assembly by detecting the rotation speed of the water pump, and control the operation of the water pump or stop or adjust the rotation speed by the estimated water level. Meanwhile, whether the water pump is blocked or not and damaged can be judged through the rotating speed of the water pump, an alarm is given in advance, and the water receiving assembly overflow fault is avoided.

In some embodiments of the invention, the water pump pumps the condensed water in the water receiving assembly to the upper part of the condenser of the air conditioner, so that the condensed water wets the condenser from top to bottom, and the water vapor formed by evaporation of the surface of the condenser is blown into the air by the fan of the air conditioner.

Further, as shown in fig. 6, the air conditioner may include a first water level detector, a compressor, and an audio/visual prompt unit, the CPU controls the water pump to start to pump the condensed water in the water receiving assembly to the upper portion of the condenser, the condensed water wets the condenser from top to bottom, and the water on the surface of the condenser is rapidly evaporated by the wind of the condenser to form water vapor which is blown into the air. Thereby achieving the circulation process from water vapor to water and then from water to water vapor. The water which flows down from the condenser and is not evaporated in time flows back to the water receiving component again. When the CPU detects that the water level in the water receiving assembly reaches the full water level through the water level sensor (namely, the first water level detection piece), the CPU controls the audible and visual prompting unit (namely, the audible and visual alarm) to prompt the full water level acoustically and/or optically. The method not only ensures that the water of the air conditioner can not overflow, but also keeps the humidity of the indoor air.

Part of the method content of the control method according to the application is described below with reference to fig. 7:

step S002: the CPU judges whether the compressor and the fan are both started, if so, the step S003 is executed, otherwise, the step S004 is executed;

step S003: the CPU controls the water pump to be started, water in the water receiving assembly is pumped into a water receiving tray on the upper portion of the condenser, the water wets the condenser from the upper portion of the condenser to the lower portion of the condenser, water on the condenser is quickly evaporated into water vapor through air of the condenser and sent into indoor air, and water which is not evaporated in time flows into the water receiving assembly from top to bottom;

step S004: the CPU detects the water level V1 in the water receiving assembly through a first water level detection piece;

step S005: the CPU detects whether the water level V1 reaches the full water level Vf through the first water level detection piece, if so, the step S006 is executed, otherwise, the step S007 is executed;

step S006: the CPU controls the audible and visual alarm to prompt water pouring when the water is full;

step S007: and returning.

The control method of the present application is described in detail below with reference to fig. 3, and includes the following specific steps:

step S01: starting a water pump after the air conditioner is started, and measuring the running rotating speed of the water pump after T0 (T0 is a natural number more than or equal to 0) time (such as 1 minute), namely first preset time;

In order to implement the above embodiments, the present invention provides a control device of an air conditioner 100, the air conditioner 100 includes a water receiving assembly 10 and a water pump 61, the water pump 61 is used for pumping condensed water in the water receiving assembly 10, the control device includes: the determination module 30 is used for determining the operation speed of the water pump 61 during the operation of the air conditioner 100, and the control module 31 is used for controlling the water pump 61 and the air conditioner 100 according to the operation speed of the water pump 61 so as to prevent the condensate water in the water receiving assembly 10 from overflowing.

Specifically, the water pump 61 is started first after the air conditioner 100 is started, the determining module 30 detects the operation rotation speed of the water pump 61 in the working process of the air conditioner 100, the determining module 30 sends the operation rotation speed information of the water pump 61 to the control module 31, and after the control module 31 receives the operation rotation speed information of the water pump 61, the control module 31 can control the water pump 61 and the air conditioner 100 according to the operation rotation speed value of the water pump 61. Specifically, when the operation rotation speed value of the water pump 61 is greater than or equal to the first rotation speed value, there is no water or little water in the water receiving assembly 10, and it is not necessary for the water pump 61 to pump water out of the water receiving assembly 10, at this time, the control module 31 controls the water pump 61 to stop working, and controls the air conditioner 100 to keep the operation state. When the operating speed value of the water pump 61 is less than the first speed value, it indicates that there is some water in the water receiving assembly 10 and it is necessary for the pump body 61 to pump water toward the outside of the water receiving assembly 10, and the control module 31 controls the water pump 61 to continue operating and controls the air conditioner 100 to keep operating. When the operation rotation speed value of the water pump 61 is smaller than the first rotation speed value and larger than the second rotation speed value, it indicates that part of the water is in the water receiving assembly 10, the control module 31 controls the water pump 61 to continue to work, and when the operation rotation speed value of the water pump 61 is smaller than the second rotation speed value and larger than the third rotation speed value, it indicates that the water in the water receiving assembly 10 is more or full of water, the control module 31 controls the operation power of the water pump 61 to be increased, and the water in the water receiving assembly 10 is discharged in time. When the operating rotating speed value of the water pump 61 is smaller than the third rotating speed value, it indicates that the impurities in the water pump 61 are blocked and locked, or the water pump motor is damaged, that is, the water pump 61 fails, the control module 31 controls the water pump 61 and the air conditioner 100 to stop working, so as to prevent the condensed water from continuously gathering in the water receiving assembly 10.

From the above, the air conditioner 100 of the present application can determine the water level condition in the water receiving assembly 10 according to the rotation speed of the water pump 61, thereby whether the water pump 61 and/or the air conditioner 100 can be controlled according to the operation rotation speed of the water pump 61 to work, the water in the water receiving assembly 10 can be timely discharged out of the water receiving assembly 10, the overflow of the condensed water in the water receiving assembly 10 can be prevented, thereby the indoor objects can be prevented from being soaked by the condensed water, and further the property loss of the user can be avoided, and compared with the prior art, the water level switch does not need to be matched with the water pump 61 to work, the water level switch does not need to be arranged on the air conditioner 100, and the problem of water leakage of the air conditioner 100 caused by the failure of the water level switch can be fundamentally avoided.

Further, when the operating speed of the water pump 61 is greater than or equal to a first preset speed (i.e., a first speed value), which indicates that there is no water in the water receiving assembly 10 or the water level is at the lowest water level, the water in the water receiving assembly 10 does not overflow the water receiving assembly 10, at this time, the control module 31 controls the water pump 61 to stop working, and the control module 31 controls the air conditioner 100 to maintain the operating state. When the operation rotational speed of water pump 61 is less than first predetermined rotational speed, control module 31 controls water pump 61 to continue work to control air conditioner 100 and keep running state, water pump 61 is operating condition this moment, and water pump 61 can be in real time with the comdenstion water pump out in the water receiving subassembly 10, can guarantee that the comdenstion water in the water receiving subassembly 10 can not spill over the water receiving subassembly 10, does not influence air conditioner 100 normal use simultaneously.

When the operation rotating speed of the water pump 61 is greater than or equal to a second preset rotating speed (i.e., a second rotating speed value), that is, when the operation rotating speed of the water pump 61 is less than the first preset rotating speed and greater than or equal to the second preset rotating speed, it indicates that part of the water exists in the water receiving assembly 10, the water pump 61 is required to pump out the water receiving assembly 10, the control module 31 controls the water pump 61 to keep operating in the current working state, at this time, the control module 31 controls the water pump 61 to continue to operate, so that the condensed water in the water receiving assembly 10 is ensured to be pumped out in time, and further, the condensed water is prevented from overflowing.

When the operating speed of the water pump 61 is greater than or equal to a third preset speed (i.e., a third speed value) and less than a second preset speed, which indicates that there is more condensed water in the water receiving assembly 10 or the water level in the water receiving assembly 10 is full, the condensed water in the water receiving assembly 10 needs to be quickly drained, the control module 31 controls to increase the operating power of the water pump 61, so that more condensed water in the water receiving assembly 10 can be pumped out in unit time, the drainage rate of the condensed water pump in the water receiving assembly 10 can be increased, thereby further preventing the condensed water from overflowing the water receiving assembly 10, and further preventing the air conditioner 100 from leaking water.

When the operation rotating speed of the water pump 61 is less than the third preset rotating speed, it indicates that the impurities in the water pump 61 are blocked and locked, or the water pump motor is damaged, that is, the water pump 61 fails, the water pump 61 cannot pump out the condensed water in the water receiving assembly 10 in time, at this time, if the air conditioner 100 continues to work, the condensed water may continue to be collected in the water receiving assembly 10, and the condensed water has a risk of overflowing the water receiving assembly 10, therefore, the water pump 61 and the air conditioner 100 are controlled to stop working through the control module 31, and the overflow of the condensed water in the water receiving assembly 10 can be further avoided.

When the operating speed of the water pump 61 is greater than or equal to the third preset speed and less than the second preset speed, and the duration is greater than or equal to the fourth preset time (for example, the fourth preset time is set to 1 minute), it is determined that the water receiving assembly 10 is at a full water level state, that is, the water receiving assembly 10 is full of water, and the CPU36 controls the air conditioner 100 to send a full water prompt message, so that the user knows that the water receiving assembly 10 is full of water. Then the control module 31 controls and increases the operation power of the water pump 61, so as to increase the output rate of the condensate pump in the water receiving assembly 10, thereby further preventing the condensate water from overflowing the water receiving assembly 10. However, the present invention is not limited thereto, and the control module 31 may control the air conditioner 100 to be stopped after the water receiving module 10 is filled with water.

After controlling the water pump 61 to stop operating, the method may further include: judging whether an operation instruction of the water pump 61 is received, if so, controlling the water pump 61 to start to operate, determining the operation rotating speed of the water pump 61 after first preset time, and if not, controlling the water pump 61 to start to operate when the air conditioner 100 operates in a cooling mode, and determining the operation rotating speed of the water pump 61 after the first preset time. Specifically, when the operation rotation speed of the water pump 61 is greater than or equal to a first preset rotation speed, it indicates that there is no water in the water receiving assembly 10 or the water level is at the lowest water level, the water in the water receiving assembly 10 does not overflow the water receiving assembly 10, at this time, the control module 31 controls the water pump 61 to stop working, then the control module 31 determines whether an operation instruction of the water pump 61 is received, if the control module 31 receives the operation instruction of the water pump 61, the control module 31 controls the water pump 61 to start working, and after a first preset time (for example, the first preset time is set to 1 minute), the determination module 30 determines the operation rotation speed of the water pump 61, then the determination module 30 transmits the operation rotation speed information of the water pump 61 to the control module 31, and the control module 31 may control the working states of the water pump 61 and the air conditioner 100 according to the operation rotation speed of the water pump 61, so as to prevent the condensed water from overflowing from the water receiving assembly 10.

Further, when the operation rotation speed of the water pump 61 is greater than or equal to the first preset rotation speed, it indicates that there is no water in the water receiving assembly 10 or the water level is at the lowest water level, the water in the water receiving assembly 10 does not overflow the water receiving assembly 10, at this time, the control module 31 controls the water pump 61 to stop working, then the control module 31 determines whether to receive an operation instruction of the water pump 61, if the control module 31 does not receive the operation instruction of the water pump 61, the CPU36 (central processing unit) of the air conditioner 100 detects whether the air conditioner 100 starts a cooling operation mode, if the air conditioner 100 starts the cooling operation mode, the CPU36 issues a control instruction to the control module 31, then the control module 31 controls the water pump 61 to start working, and after the first preset time, the determination module 30 determines the operation rotation speed of the water pump 61, then the determination module 30 transmits the operation rotation speed information of the water pump 61 to the control module 31, and the control module 31 can control the operation states of the water pump 61 and the air conditioner 100 according to the operation rotation speed of the water pump 61, thereby preventing the condensate from overflowing from the water receiving assembly 10.

In some embodiments of the present invention, as shown in fig. 5, the air conditioner 100 may further include: the CPU36, the display unit 37, the storage unit 38 and the power supply unit 39, the CPU36 controls the operation of the whole system of the air conditioner including the water pump 61, the storage unit 38 stores necessary information, the display unit 37 displays the operation information and fault information (including the fault information of the water pump 61) of the air conditioner 100, the control module 31 controls the operation of parts of the air conditioner 100 including the water pump 61 and detects the operation rotating speed of the water pump 61. The power supply unit 39 supplies power to the entire system of the air conditioner including the CPU36, the storage unit 38, the display unit 37, the control module 31, the water pump 61, and the like. The CPU36 exchanges information with the storage unit 38. The CPU36 controls the display unit 37 to display, and the CPU36 exchanges information with the control module 31, issues a control instruction to the control module 31, and collects information such as control information and component operation conditions fed back by the control module 31.

In some embodiments of the present invention, when the operation instruction of the water pump 61 is not received and the air conditioner 100 does not start cooling operation, it is determined whether the air conditioner 100 is stopped, wherein if so, i.e., the air conditioner 100 is stopped, the water pump 61 is controlled to keep a stop working state, if not, i.e., the air conditioner 100 is not stopped, the control module 31 controls the water pump 61 to start operation when the operation time of the air conditioner 100 is greater than or equal to a second preset time (e.g., the second preset time is 1 minute), and the determination module 30 determines the operation rotation speed of the water pump 61 after the first preset time.

Specifically, when the operation rotation speed of the water pump 61 is greater than or equal to a first preset rotation speed, at this time, the control module 31 controls the water pump 61 to stop working, then the control module 31 determines whether an operation instruction of the water pump 61 is received, if the control module 31 does not receive the operation instruction of the water pump 61 and the air conditioner 100 does not start the cooling mode, then the CPU36 detects whether the air conditioner 100 is stopped, if the air conditioner 100 is in a stopped state, the control module 31 controls the water pump 61 to stop working, if the air conditioner 100 is not in a stopped state, when the operation time of the air conditioner 100 is greater than or equal to a second preset time, after the water pump 61 is started for the first preset time, the determination module 30 determines the operation rotation speed of the water pump 61, then the determination module 30 transmits the operation rotation speed information of the water pump 61 to the control module 31, and the control module 31 may control the operation states of the water pump 61 and the air conditioner 100 according to the operation rotation speed of the water pump 61, so as to prevent condensed water from overflowing from the water collecting assembly 10.

In some embodiments of the present invention, when the operation rotation speed of the water pump 61 is less than the third preset rotation speed and continues for the third preset time, if the control module 31 does not receive the stop instruction of the water pump 61, the determination module 30 continues to determine whether the operation rotation speed of the water pump 61 is less than the third preset rotation speed, wherein if yes, that is, the determination module 30 determines that the operation rotation speed of the water pump 61 is less than the third preset rotation speed, it is determined that the water pump 61 fails, and the water pump failure counter counts the number of failures, and the control module 31 controls the water pump 61 to stop operating, and when the number of failures is greater than or equal to the first preset number (the first preset number may be set to 3), the control module 31 controls the air conditioner 100 to stop operating, so that the air conditioner 100 can be prevented from continuously generating condensed water during cooling, and the condensed water collecting assembly 10 can be effectively prevented from overflowing.

Further, the air conditioner 100 may further include a display unit 37, for example: the display unit 37 is a display screen, and after the water pump 61 is determined to have a fault, the CPU36 controls the display unit 37 to display a fault code of the water pump 61, and/or the CPU36 controls the control module 31 to control and light an indicator light indicating the fault of the water pump 61.

The air conditioner 100 of the present invention may estimate the water level in the water receiving module 10 by detecting the rotation speed of the water pump 61, and control the operation of the water pump 61 or stop or adjust the rotation speed by the estimated water level. Meanwhile, whether the water pump 61 is blocked or damaged can be judged through the rotating speed of the water pump 61, an alarm is given in advance, and the water receiving assembly 10 overflow fault is avoided.

In some embodiments of the present invention, the water pump 61 pumps the condensed water in the water receiving assembly 10 to the upper portion of the condenser 20 of the air conditioner 100, so that the condensed water wets the condenser 20 from top to bottom, and the air is blown into the air by the fan 35 of the air conditioner 100, which can discharge the condensed water to the outside of the air conditioner 100, thereby preventing the condensed water from being largely accumulated in the water receiving assembly 10, increasing the humidity of the indoor air, and preventing the indoor air from being dried.

Further, as shown in fig. 6, the air conditioner 100 may include a first water level detector 32, a compressor 33 and an audible and visual prompting unit 34, the cpu36 controls the water pump 61 to be turned on to pump the condensed water in the water receiving assembly 10 to the upper portion of the condenser 20, the condensed water wets the condenser 20 from top to bottom, and simultaneously the water on the surface of the condenser 20 is rapidly evaporated by the wind of the condenser 20 to form water vapor to be blown into the air. Thereby achieving the circulation process from water vapor to water and then from water to water vapor. The water which flows down the condenser 20 and is not evaporated in time flows back to the water receiving assembly 10 again. When the CPU36 detects that the water level in the water receiving assembly 10 reaches the full water level through the water level sensor (i.e., the first water level detecting member 32), the CPU36 controls the audible and/or visual alarm unit 34 (i.e., audible and visual alarm) to provide an audible and/or visual full water alarm. This method ensures that the water in the air conditioner 100 does not overflow and maintains the humidity of the indoor air.
