Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and in particular to an air conditioner control method, an air conditioner, and a computer-readable storage medium. Background Technology

[0002] Currently, portable air conditioners with related technologies can cool the kitchen environment during use, improving the comfort of the kitchen to a certain extent. Specifically, in portable air conditioners with related technologies, the water produced on the evaporator flows into the water collection tray, and then the water pump motor uses a water pumping wheel to disperse the condensate produced by the evaporator onto the hotter condenser. After the condensate on the condenser is evaporated, it is discharged to the outside through the air duct connected to the lower air duct, thus realizing the drainage-free function of the portable air conditioner.

[0003] However, the related technical problem is that, because a lot of hot water vapor is generated in the kitchen during the cooking process, when the portable air conditioner runs in a hot and humid environment for a long time, it is very easy for the water level to fill up and shut down. This requires users to manually drain the water before they can restart the portable air conditioner, which greatly affects the user experience. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the first objective of this invention is to provide a control method for an air conditioner that can effectively control the water level of condensate in the water collection assembly, preventing the air conditioner from shutting down due to full water level, thus eliminating the need for the user to manually drain the water and restart the air conditioner, and improving the user experience.

[0005] The second objective of this invention is to provide an air conditioner.

[0006] A third objective of this invention is to provide a computer-readable storage medium.

[0007] The fourth objective of this invention is to propose another type of air conditioner.

[0008] To achieve the above objectives, a first aspect of the present invention provides a control method for an air conditioner, wherein the air conditioner includes a compressor, an evaporator, a condenser, a throttling element, a water collection assembly, and a spray assembly. The water collection assembly is used to collect condensate generated during the heat exchange operation of the evaporator, and the spray assembly is used to spray the condensate onto the condenser. The method includes: when the air conditioner is running, obtaining the water level of the condensate in the water collection assembly; when the water level of the condensate is greater than or equal to a first preset water level, controlling the operating frequency of the compressor to increase to a preset maximum frequency and controlling the fan speed on the evaporator side to increase, and / or controlling the fan speed on the condenser side to decrease to a preset first speed and controlling the spray rate of the spray assembly to increase, so as to avoid the air conditioner shutting down due to full water level.

[0009] According to the air conditioner control method proposed in this embodiment, when the air conditioner is running, the water level of the condensate in the water collection assembly is acquired. When the condensate water level is greater than or equal to a first preset water level, the operating frequency of the compressor is increased to a preset maximum frequency, and the fan speed on the evaporator side is increased. Alternatively, the fan speed on the condenser side is decreased to a preset first speed, and the spray rate of the spray assembly is increased, to prevent the air conditioner from shutting down due to full water level. Thus, the water level of the condensate in the water collection assembly is effectively controlled, preventing the air conditioner from shutting down due to full water level, thereby eliminating the need for the user to manually drain the water and restart the air conditioner, improving the user experience.

[0010] In addition, the air conditioner control method proposed in the above embodiments of the present invention may also have the following additional technical features:

[0011] According to one embodiment of the present invention, after controlling the operating frequency of the compressor to increase to a preset maximum frequency, controlling the fan speed on the evaporator side to increase, and controlling the fan speed on the condenser side to decrease to a preset first speed, and controlling the spray rate of the spray assembly to increase, the method further includes: obtaining the pipe temperature of the condenser; when the pipe temperature of the condenser is greater than a first preset temperature, controlling the compressor to decrease its operating frequency, and controlling the fan speed on the condenser side to increase, until the water level of the condensate is less than the first preset water level, and then controlling the air conditioner to resume normal operation.

[0012] According to an embodiment of the present invention, when the air conditioner receives a shutdown command, the method further includes: if the water level of the condensate is less than or equal to a second preset water level, controlling the fan speed on the evaporator side to reduce the preset second speed, and controlling the operating frequency of the compressor and the fan speed on the condenser side according to the current indoor temperature and current indoor humidity, and controlling the spray device to stop working so that the air conditioner produces water, wherein the second preset water level is less than the first preset water level.

[0013] According to one embodiment of the present invention, after the air conditioner produces water, the method further includes: determining the water production time of the air conditioner; when the water production time reaches a preset time, controlling the air conditioner to stop operating, and using the environment to defrost the evaporator.

[0014] According to one embodiment of the present invention, when the air conditioner receives a shutdown command, the method further includes: if the water level of the condensate is greater than or equal to a first preset water level, controlling the operating frequency of the compressor to increase to a preset maximum frequency and controlling the fan speed on the evaporator side to increase, and / or controlling the fan speed on the condenser side to decrease to a preset first speed and controlling the spray rate of the spray assembly to increase, so that the air conditioner consumes water; during the process of the air conditioner consuming water, if the pipe temperature of the condenser is greater than a first preset temperature, controlling the compressor to decrease its operating frequency and controlling the fan speed on the condenser side to increase, until the water level of the condensate is less than the first preset water level, and then controlling the air conditioner to stop operating.

[0015] According to one embodiment of the present invention, when the air conditioner receives a shutdown command, the method further includes: if the water level of the condensate is greater than a second preset water level and less than a first preset water level, then controlling the air conditioner to shut down directly.

[0016] According to one embodiment of the present invention, the spray assembly includes a water pump motor, wherein controlling the spray rate of the spray assembly to increase includes: controlling the rotation speed of the water pump motor to increase to a preset maximum rotation speed.

[0017] To achieve the above objectives, the air conditioner proposed in the second aspect of the present invention includes a memory, a processor, and a control program for the air conditioner stored in the memory and executable on the processor. When the processor executes the control program for the air conditioner, it implements the control method for the air conditioner as described in the first aspect of the present invention.

[0018] According to the embodiments of the present invention, the air conditioner can effectively control the water level of condensate in the water collection component by running the control program of the air conditioner stored in the memory through the processor, so as to avoid the air conditioner shutting down when the water is full. This eliminates the need for the user to manually drain the water and restart the air conditioner, thus improving the user experience.

[0019] To achieve the above objectives, a computer-readable storage medium is provided in the third aspect of the present invention, on which a control program for an air conditioner is stored. When the control program for the air conditioner is executed by a processor, it implements the control method for the air conditioner as described in the first aspect of the present invention.

[0020] According to the computer-readable storage medium proposed in the embodiments of the present invention, by executing the control program of the air conditioner stored thereon through the processor, the water level of the condensate in the water collection assembly can be effectively controlled, avoiding the phenomenon of the air conditioner stopping when the water is full, thus eliminating the need for the user to manually drain the water and restart the air conditioner, thereby improving the user experience.

[0021] To achieve the above objectives, an air conditioner according to a fourth aspect embodiment of the present invention includes: a compressor, an evaporator, a condenser, a throttling element, a water collection assembly, and a spray assembly. The water collection assembly is used to collect condensate generated during the heat exchange operation of the evaporator, and the spray assembly is used to spray the condensate onto the condenser. A control unit is used to, during the operation of the air conditioner, acquire the water level of the condensate in the water collection assembly, and when the water level of the condensate is greater than or equal to a first preset water level, control the operating frequency of the compressor to increase to a preset maximum frequency and control the fan speed on the evaporator side to increase, and / or control the fan speed on the condenser side to decrease to a preset first speed and control the spray rate of the spray assembly to increase, so as to avoid the air conditioner shutting down due to water overflow.

[0022] According to an embodiment of the present invention, an air conditioner collects condensate generated during evaporator heat exchange via a water collection assembly, and sprays the condensate onto the condenser via a spray assembly. During air conditioner operation, a control unit acquires the condensate level in the water collection assembly. When the condensate level is greater than or equal to a first preset level, the control unit increases the compressor's operating frequency to a preset maximum frequency and increases the evaporator-side fan speed, and / or decreases the condenser-side fan speed to a preset first speed and increases the spray rate of the spray assembly to prevent the air conditioner from shutting down due to overfilling. This effectively controls the condensate level in the water collection assembly, preventing the air conditioner from shutting down due to overfilling, thus eliminating the need for manual drainage and restarting, and improving the user experience.

[0023] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0032] Figure 9 This is a block diagram of an air conditioner according to an embodiment of the present invention. Detailed Implementation

[0033] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote 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 exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] The control method for an air conditioner, the air conditioner, and the computer storage medium according to embodiments of the present invention are described below with reference to the accompanying drawings.

[0035] Specifically, in some examples of the present invention, the air conditioner may include a compressor, an evaporator, a condenser, a throttling element, a water collection assembly, and a spray assembly, wherein the water collection assembly is used to collect the condensate generated during the heat exchange operation of the evaporator, and the spray assembly is used to spray the condensate onto the condenser.

[0036] Specifically, in some embodiments of the present invention, such as Figure 1As shown, the air conditioner may also include an air inlet a1, an air outlet a2, a hot exhaust air inlet b1, a hot exhaust air outlet b2, and an air conditioning unit c. The airflow between the air inlet a1 and the air outlet a2 is designed in an arc shape.

[0037] Furthermore, such as Figure 2 As shown, evaporator A and condenser B are located at the upper and lower ends of the shell, arranged diagonally from left to right. Evaporator A and condenser B are arranged in a straight line. Fan assemblies A1 and B1 are also installed on the sides of evaporator A and condenser B. Fan assemblies A1 and B1 may include a motor, impeller and bracket. Optionally, the impeller may be preferably a centrifugal impeller.

[0038] It should be understood that in some embodiments of the present invention, when the air conditioner is in cooling operation, the condensate collected by the water collection assembly during the evaporator heat exchange can be sprayed onto the condenser through the spray assembly, so that the condensate is evaporated by the hotter condenser, and then discharged to the outside. However, if the condensate generated during the evaporator heat exchange is generated faster than the condensate discharged to the outside, the air conditioner is very likely to shut down due to full water. In this case, the user needs to drain the condensate from the air conditioner before restarting the air conditioner, which affects the user's normal operating experience.

[0039] To address this, this invention proposes a control method for an air conditioner that can effectively control the water level of condensate in the water collection assembly, preventing the air conditioner from shutting down due to full water level. This eliminates the need for users to manually drain the water and restart the air conditioner, thus improving the user experience.

[0040] Figure 3 This is a flowchart illustrating the control method of an air conditioner according to an embodiment of the present invention.

[0041] like Figure 3 As shown, the control methods for air conditioners include:

[0042] S101, during air conditioner operation, obtain the water level of condensate in the water collection assembly.

[0043] Specifically, when the air conditioner is running, the compressor, evaporator, condenser, throttling element and spray assembly can be controlled to start running, and the water level of condensate in the water collection assembly can be obtained through the water level sensor installed in the water collection assembly.

[0044] S102, when the condensate water level is greater than or equal to the first preset water level, control the compressor operating frequency to increase to the preset maximum frequency and control the evaporator side fan speed to increase, and / or control the condenser side fan speed to decrease to the preset first speed and control the spray rate of the spray assembly to increase, so as to avoid the air conditioner shutting down due to full water.

[0045] Specifically, in some embodiments of the present invention, when the condensate level is greater than or equal to a first preset level, the operating frequency of the compressor can be increased to a preset maximum frequency, and the fan speed on the evaporator side can be increased to improve the evaporation temperature and airflow on the evaporator side, thereby reducing the amount of condensate produced. This effectively controls the condensate level in the water collection assembly, preventing the air conditioner from shutting down due to full water level. It also eliminates the need for the user to manually drain the water and restart the air conditioner, thus improving the user experience.

[0046] Alternatively, in some embodiments of the present invention, when the condensate water level is greater than or equal to a first preset water level, the fan speed on the condenser side can be reduced to a preset first speed, and the spray rate of the spray assembly can be increased to spray as much condensate water as possible onto the condenser. The air volume on the condenser side can be reduced, thereby increasing the evaporation of condensate water. This effectively controls the condensate water level in the water collection assembly, preventing the air conditioner from shutting down due to full water level. Users do not need to manually drain the water and then restart the air conditioner, thus improving the user experience.

[0047] Alternatively, in some embodiments of the present invention, when the condensate level is greater than or equal to a first preset level, the operating frequency of the compressor can be increased to a preset maximum frequency, and the fan speed on the evaporator side can be increased to raise the evaporation temperature and airflow on the evaporator side, thereby reducing the amount of condensate produced. Simultaneously, the fan speed on the condenser side can be reduced to a preset first speed, and the spray rate of the spray assembly can be increased to spray as much condensate as possible onto the condenser, while reducing the airflow on the condenser side, thereby increasing the evaporation rate of the condensate. Thus, the condensate level in the water collection assembly is effectively controlled, preventing the air conditioner from shutting down due to full water level, eliminating the need for manual drainage and restarting, and improving the user experience.

[0048] Optionally, in the above embodiments of the present invention, the difference between the condensate water level and the first preset water level can be used as the target water consumption of the air conditioner. The first preset water level can be the warning water level when the air conditioner stops due to full water, and it can be set accordingly based on the water collection capacity of the water collection component.

[0049] It should be understood that in some embodiments of the present invention, when the condensate level is greater than or equal to a first preset level, the condensate level in the water collection assembly is considered too high, and there is a possibility that the air conditioner will shut down due to full water level. In this case, the amount of condensate generated and / or the amount of condensate evaporation can be reduced by controlling the compressor operating frequency to a preset maximum frequency and controlling the fan speed on the evaporator side to increase, and / or by controlling the fan speed on the condenser side to decrease to a preset first speed and controlling the spray rate of the spray assembly to increase, so as to effectively control the condensate level in the water collection assembly, avoid the air conditioner from shutting down due to full water level, and thus eliminate the need for the user to manually drain the water and restart the air conditioner, thereby improving the user experience.

[0050] Furthermore, such as Figure 4 As shown, after controlling the compressor's operating frequency to increase to a preset maximum frequency, and controlling the evaporator-side fan speed to increase, and controlling the condenser-side fan speed to decrease to a preset first speed, and controlling the spray rate of the spray assembly to increase, the method further includes:

[0051] S201, obtain the tube temperature of the condenser.

[0052] Specifically, the tube temperature of the condenser can be obtained through a temperature sensor installed at the condenser.

[0053] S202: When the condenser pipe temperature is higher than the first preset temperature, control the compressor to reduce its operating frequency and control the fan speed on the condenser side to increase until the condensate water level is lower than the first preset water level, then control the air conditioner to resume normal operation.

[0054] Specifically, it can be determined whether the condenser is in a high-temperature state by judging whether the condenser pipe temperature is greater than the first preset temperature. When the condenser pipe temperature is greater than the first preset temperature, the compressor can be controlled to reduce its operating frequency and the fan speed on the condenser side can be controlled to increase until the condensate water level is lower than the first preset water level, and then the air conditioner can be controlled to resume normal operation.

[0055] Optionally, the first preset temperature can be set according to the temperature of the environment where the air conditioner is located.

[0056] It is understood that in some embodiments of the present invention, when the condensate water level is lower than the first preset water level, it can be assumed that the air conditioner will not shut down due to full water level. At this time, the air conditioner can be controlled to resume normal operation to ensure that the cooling function of the air conditioner can operate stably.

[0057] It should be understood that in some embodiments of the present invention, when the condenser tube temperature is greater than the first preset temperature, in order to avoid the condenser operating at high temperature for a long time, the compressor can be controlled to reduce its operating frequency and the fan speed on the condenser side can be controlled to increase until the condensate water level is lower than the first preset water level. Then, the air conditioner can be controlled to resume normal operation. This ensures the stable operation of the air conditioner while effectively controlling the condensate water level in the water collection assembly, preventing the air conditioner from shutting down due to full water level. This eliminates the need for the user to manually drain the water and restart the air conditioner, thus improving the user experience.

[0058] Furthermore, when the air conditioner receives a shutdown command, the method further includes: if the condensate water level is less than or equal to a second preset water level, controlling the fan speed on the evaporator side to reduce the preset second speed, and controlling the compressor operating frequency and the fan speed on the condenser side according to the current indoor temperature and current indoor humidity, and controlling the spray device to stop working so that the air conditioner produces water, wherein the second preset water level is less than the first preset water level.

[0059] Specifically, when the air conditioner receives a shutdown command, it can determine whether the condensate water level in the water collection assembly is at a reasonable level by judging whether the condensate water level is less than or equal to the second preset water level. If the condensate water level is less than or equal to the second preset water level, the fan speed on the evaporator side is reduced to the preset second speed, and the operating frequency of the compressor and the fan speed on the condenser side are controlled according to the current indoor temperature and humidity. The spray device is also controlled to stop working so that the air conditioner can produce water. The second preset water level is less than the first preset water level.

[0060] Optionally, in the above embodiments of the present invention, the difference between the condensate water level and the second preset water level can be used as the target water production of the air conditioner, and the second preset water level can be set accordingly based on the water collection capacity of the water collection component.

[0061] It should be understood that, in some embodiments of the present invention, when the air conditioner receives a shutdown command and the condensate water level is less than or equal to a second preset water level, the fan speed on the evaporator side can be reduced to a preset second speed, and the operating frequency of the compressor and the fan speed on the condenser side can be controlled according to the current indoor temperature and humidity, as well as the spray device can be stopped to enable the air conditioner to produce water, thereby effectively controlling the condensate water level in the water collection assembly, avoiding the condensate water level from being too low, and ensuring the stable cooling operation of the air conditioner while keeping the condensate water level in the water collection assembly at a reasonable level.

[0062] Furthermore, such as Figure 5 As shown, after the air conditioner produces water, the method also includes:

[0063] S301, determine the water production time of the air conditioner.

[0064] Specifically, the target water production of the air conditioner can be determined based on the difference between the condensate water level and the second preset water level, and then the water production time of the air conditioner can be determined based on the target water production. For example, the water production time of the air conditioner can be the time it takes for the condensate water level in the water collection assembly to reach the second preset water level.

[0065] S302 controls the air conditioner to stop operating when the water production time reaches the preset time, and uses the environment to defrost the evaporator.

[0066] Specifically, it can be determined whether the degree of frost on the evaporator can meet the water production requirements of the air conditioner by judging whether the water production time has reached the preset time. When the water production time reaches the preset time, the air conditioner is controlled to stop running, and the environment is used to defrost the evaporator.

[0067] Optionally, defrosting the evaporator can be performed by dynamically adjusting the operating speed of the fan and / or the operating frequency of the compressor on the evaporator side based on the water level of the condensate in the water collection assembly and the ambient temperature and humidity, thereby adjusting the condensate production.

[0068] It should be understood that, in some embodiments of the present invention, when the water production time reaches a preset time, it can be considered that the degree of frost on the evaporator meets the water production requirements of the air conditioner. At this time, the air conditioner can be controlled to stop running, and the environment can be used to defrost the evaporator so that the water level of the condensate in the water collection assembly is restored to the second preset water level, thereby keeping the water level of the condensate in the water collection assembly at a reasonable level.

[0069] Furthermore, such as Figure 6 As shown, when the air conditioner receives a shutdown command, the method also includes:

[0070] S401, if the condensate water level is greater than or equal to the first preset water level, the compressor operating frequency is increased to the preset maximum frequency, and the evaporator side fan speed is increased, and / or the condenser side fan speed is decreased to the preset first speed, and the spray rate of the spray assembly is increased, so that the air conditioner consumes water.

[0071] Specifically, in some embodiments of the present invention, when the air conditioner receives a shutdown command and the condensate water level is greater than or equal to a first preset water level, the operating frequency of the compressor can be increased to a preset maximum frequency, and the fan speed on the evaporator side can be increased to improve the evaporation temperature of the evaporator and the air volume on the evaporator side, thereby causing the air conditioner to consume water and reduce the amount of condensate water produced. This effectively controls the condensate water level in the water collection assembly, preventing the air conditioner from shutting down due to full water level. It also eliminates the need for the user to manually drain the water and restart the air conditioner, thus improving the user experience.

[0072] Alternatively, in some embodiments of the present invention, when the air conditioner receives a shutdown command and the condensate water level is greater than or equal to a first preset water level, the fan speed on the condenser side can be reduced to a preset first speed, and the spray rate of the spray assembly can be increased to spray as much condensate water as possible onto the condenser. The air volume on the condenser side can be reduced to make the air conditioner consume water, thereby increasing the evaporation of condensate water. This effectively controls the condensate water level in the water collection assembly, preventing the air conditioner from shutting down due to full water level. The user does not need to manually drain the water and then restart the air conditioner, thus improving the user experience.

[0073] Alternatively, in some embodiments of the present invention, when the air conditioner receives a shutdown command and the condensate water level is greater than or equal to a first preset water level, the compressor's operating frequency can be increased to a preset maximum frequency, and the evaporator-side fan speed can be increased to raise the evaporator's evaporation temperature and airflow, causing the air conditioner to consume water and thus reducing condensate production. Simultaneously, the condenser-side fan speed can be reduced to a preset first speed, and the spray rate of the spray assembly can be increased to spray as much condensate water as possible onto the condenser, while reducing the condenser-side airflow, causing the air conditioner to consume water and thus increasing condensate evaporation. Therefore, the condensate water level in the water collection assembly is effectively controlled, preventing the air conditioner from shutting down due to full water level, eliminating the need for manual drainage and restarting, and improving the user experience.

[0074] S402: During the water consumption process of the air conditioner, if the pipe temperature of the condenser is higher than the first preset temperature, the compressor is controlled to reduce its operating frequency, and the fan speed on the condenser side is controlled to increase until the water level of the condensate is lower than the first preset water level, and then the air conditioner is controlled to stop operating.

[0075] Specifically, it can be determined whether the condenser is in a high-temperature state by judging whether the condenser pipe temperature is greater than the first preset temperature. When the condenser pipe temperature is greater than the first preset temperature, the compressor can be controlled to reduce its operating frequency and the fan speed on the condenser side can be controlled to increase until the condensate water level is lower than the first preset water level, and then the air conditioner can be controlled to resume normal operation.

[0076] It should be understood that, in some embodiments of the present invention, when the air conditioner receives a shutdown command and the condensate water level is greater than or equal to a first preset water level, the operating frequency of the compressor can be increased to a preset maximum frequency, and the fan speed on the evaporator side can be increased, and / or the fan speed on the condenser side can be decreased to a preset first speed, and the spray rate of the spray assembly can be increased, so that the air conditioner consumes water, thereby effectively controlling the condensate water level in the water collection assembly and avoiding the air conditioner from shutting down due to excessively high condensate water levels.

[0077] Furthermore, when the air conditioner receives a shutdown command, the method also includes: if the condensate water level is greater than a second preset water level and less than a first preset water level, then control the air conditioner to shut down directly.

[0078] It should be understood that, in some embodiments of the present invention, when the air conditioner receives a shutdown command and the condensate water level is greater than the second preset water level and less than the first preset water level, the condensate water level in the water collection assembly can be considered to be at a reasonable water level. In this case, there is no need to control the condensate water level in the water collection assembly, and the air conditioner can be directly shut down.

[0079] Furthermore, the spray assembly includes a water pump motor, wherein controlling the spray rate of the spray assembly to increase includes: controlling the rotation speed of the water pump motor to increase to a preset maximum rotation speed.

[0080] It should be understood that, in some embodiments of the present invention, the rotation speed of the water pump motor can be increased to a preset maximum speed to control the spray rate of the spray assembly, thereby allowing as much condensate in the water collection assembly as possible to be sprayed onto the condenser, increasing the evaporation rate of the condensate.

[0081] The following is in conjunction with the appendix Figure 7-8 The specific execution steps of the air conditioner control method of the present invention will be described with reference to several specific embodiments of the present invention.

[0082] Specifically, according to a specific embodiment of the present invention, such as Figure 7 As shown, after the user turns on the air conditioner, step S10 is executed.

[0083] S10 controls the compressor, evaporator, condenser, throttling element and spray assembly to start operation, and obtains the water level of condensate in the water collection assembly.

[0084] S11, determine whether the condensate water level is greater than or equal to the first preset water level. If yes, proceed to step S12; otherwise, proceed to step S14.

[0085] S12, control the compressor's operating frequency to increase to a preset maximum frequency, and control the fan speed on the evaporator side to increase, and / or control the fan speed on the condenser side to decrease to a preset first speed, and control the spray rate of the spray assembly to increase.

[0086] S13: Obtain the condenser tube temperature, and when the condenser tube temperature is greater than the first preset temperature, control the compressor to reduce its operating frequency and control the fan speed on the condenser side to increase until the condensate water level is less than the first preset water level, then control the air conditioner to resume normal operation.

[0087] S14 controls the air conditioner to operate in cooling mode.

[0088] Furthermore, according to another specific embodiment of the present invention, such as Figure 8 As shown, after the user turns off the air conditioner, the water level of the condensate is obtained. If the water level of the condensate is greater than or equal to the first preset water level, step S20 is executed. If the water level of the condensate is less than the first preset water level but greater than the second preset water level, step S22 is executed. If the water level of the condensate is less than the second preset water level, step S23 is executed.

[0089] S20, control the compressor's operating frequency to increase to a preset maximum frequency, and control the evaporator-side fan speed to increase, and / or control the condenser-side fan speed to decrease to a preset first speed, and control the spray rate of the spray assembly to increase, so that the air conditioner consumes water.

[0090] S21. During the water consumption process of the air conditioner, if the pipe temperature of the condenser is higher than the first preset temperature, the compressor is controlled to reduce its operating frequency, and the fan speed on the condenser side is controlled to increase until the water level of the condensate is lower than the first preset water level, and then the air conditioner is controlled to stop operating.

[0091] S22, controls the air conditioner to turn off directly.

[0092] S23, control the fan speed on the evaporator side to reduce the preset second speed, and control the operating frequency of the compressor and the fan speed on the condenser side according to the current indoor temperature and humidity, and control the spray device to stop working so that the air conditioner produces water, and determine the water production time of the air conditioner.

[0093] S24: During the water production process of the air conditioner, if the water production time reaches the preset time, the air conditioner is controlled to stop running, and the evaporator is defrosted using the environment until the condensate water level is higher than the second preset water level, at which point the air conditioner is controlled to stop running.

[0094] In summary, according to the air conditioner control method proposed in this embodiment of the invention, when the air conditioner is running, the water level of the condensate in the water collection assembly is obtained. When the water level of the condensate is greater than or equal to a first preset water level, the operating frequency of the compressor is increased to a preset maximum frequency, and the fan speed on the evaporator side is increased. Alternatively, the fan speed on the condenser side is decreased to a preset first speed, and the spray rate of the spray assembly is increased, to prevent the air conditioner from shutting down due to full water level. Therefore, the water level of the condensate in the water collection assembly is effectively controlled, preventing the air conditioner from shutting down due to full water level, thus eliminating the need for the user to manually drain the water and restart the air conditioner, improving the user experience.

[0095] Based on the air conditioner control method of the foregoing embodiments of the present invention, the present invention also proposes an air conditioner, including a memory, a processor, and an air conditioner control program stored in the memory and executable on the processor. When the processor executes the air conditioner control program, it implements the air conditioner control method of the foregoing embodiments of the present invention.

[0096] It should be noted that, in the embodiments of the present invention, when the processor executes the control program of the air conditioner, it can implement the specific implementation methods of the air conditioner control method in the aforementioned embodiments of the present invention one by one. In order to reduce redundancy, it will not be described again here.

[0097] In summary, the air conditioner proposed in the embodiments of the present invention can effectively control the water level of condensate in the water collection assembly by running the control program of the air conditioner stored in the memory through the processor, thereby avoiding the phenomenon of the air conditioner stopping when the water is full. This eliminates the need for the user to manually drain the water and then restart the air conditioner, thus improving the user experience.

[0098] Based on the air conditioner control method of the foregoing embodiments of the present invention, the present invention also proposes a computer-readable storage medium storing an air conditioner control program thereon. When the air conditioner control program is executed by a processor, it implements the air conditioner control method of the foregoing embodiments of the present invention.

[0099] It should be noted that, in the embodiments of the present invention, when the processor runs the control program of the air conditioner, it can implement the specific implementation methods of the air conditioner control method in the aforementioned embodiments of the present invention one by one. In order to reduce redundancy, it will not be described again here.

[0100] In summary, the computer-readable storage medium proposed in the embodiments of the present invention can effectively control the water level of condensate in the water collection assembly by executing the control program of the air conditioner stored thereon through the processor, thereby preventing the air conditioner from shutting down due to full water and eliminating the need for the user to manually drain the water and restart the air conditioner, thus improving the user experience.

[0101] Figure 9This is a block diagram of an air conditioner according to an embodiment of the present invention.

[0102] like Figure 9 As shown, the air conditioner 100 includes: a compressor 10, an evaporator 20, a condenser 30, a throttling element 40, a water collection assembly 50, a spray assembly 60, and a control unit 70.

[0103] Specifically, the water collection assembly 50 is used to collect the condensate generated during the heat exchange operation of the evaporator 20, and the spray assembly 60 is used to spray the condensate onto the condenser 30; the control unit 70 is used to obtain the water level of the condensate in the water collection assembly when the air conditioner is running, and when the water level of the condensate is greater than or equal to a first preset water level, control the compressor operating frequency to increase to a preset maximum frequency and control the fan speed on the evaporator side to increase, and / or control the fan speed on the condenser side to decrease to a preset first speed and control the spray rate of the spray assembly to increase, so as to avoid the air conditioner from shutting down due to water overflow.

[0104] In addition, the compressor 10 can be used to compress the refrigerant between the evaporator 20 and the condenser 30, and the throttling element 40 can control the flow rate of the refrigerant between the evaporator 20 and the condenser 30.

[0105] Furthermore, the control unit 70 is also used to acquire the tube temperature of the condenser; when the tube temperature of the condenser is greater than the first preset temperature, control the compressor to reduce its operating frequency and control the fan speed on the condenser side to increase until the water level of the condensate is less than the first preset water level, and then control the air conditioner to resume normal operation.

[0106] Furthermore, the control unit 70 is also configured to, if the condensate water level is less than or equal to the second preset water level, control the fan speed on the evaporator side to reduce the preset second speed, and control the operating frequency of the compressor and the fan speed on the condenser side according to the current indoor temperature and current indoor humidity, and control the spray device to stop working so that the air conditioner produces water, wherein the second preset water level is less than the first preset water level.

[0107] Furthermore, the control unit 70 is also used to determine the water production time of the air conditioner; when the water production time reaches the preset time, it controls the air conditioner to stop running and uses the environment to defrost the evaporator.

[0108] Furthermore, when the air conditioner receives a shutdown command, the control unit 70 is also configured to, if the condensate water level is greater than or equal to a first preset water level, control the compressor operating frequency to increase to a preset maximum frequency and control the evaporator-side fan speed to increase, and / or control the condenser-side fan speed to decrease to a preset first speed and control the spray rate of the spray assembly to increase, so that the air conditioner consumes water; during the process of the air conditioner consuming water, if the condenser pipe temperature is greater than a first preset temperature, control the compressor to decrease its operating frequency and control the condenser-side fan speed to increase until the condensate water level is less than the first preset water level, and then control the air conditioner to stop operating.

[0109] Furthermore, when the air conditioner receives a shutdown command, the control unit 70 is also used to control the air conditioner to shut down directly if the condensate water level is greater than the second preset water level and less than the first preset water level.

[0110] Furthermore, the spray assembly includes a water pump motor, and the control unit 70 is also used to control the rotation speed of the water pump motor to increase to a preset maximum rotation speed, so as to control the spray rate of the spray assembly to increase.

[0111] It should be noted that the specific implementation of the air conditioner in the embodiments of the present invention can refer to the specific implementation of the control method of the air conditioner in the foregoing embodiments of the present invention. To reduce redundancy, it will not be described again here.

[0112] In summary, the air conditioner proposed in this embodiment of the invention collects condensate generated during the heat exchange of the evaporator through a water collection assembly, sprays the condensate onto the condenser through a spray assembly, and, during air conditioner operation, the control unit acquires the condensate level in the water collection assembly. When the condensate level is greater than or equal to a first preset level, the control unit increases the compressor's operating frequency to a preset maximum frequency and increases the evaporator-side fan speed, and / or decreases the condenser-side fan speed to a preset first speed and increases the spray rate of the spray assembly, thereby preventing the air conditioner from shutting down due to overfilling. Thus, the condensate level in the water collection assembly is effectively controlled, preventing the air conditioner from shutting down due to overfilling, eliminating the need for the user to manually drain the water and restart the air conditioner, improving the user experience.
