Therefore, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0054] The embodiments of the present application provide a control method for a window air conditioner, a window air conditioner, and a storage medium, which are described in detail below.

[0055] The control method of a window air conditioner in an embodiment of the present invention is applied to a control device of a window air conditioner. The control device of the window air conditioner is arranged in the window air conditioner. The window air conditioner is provided with one or more processors, memories, and one or more applications, wherein the one or more applications are stored in the memories and configured to be executed by the processor to implement the control method of the window air conditioner.

[0056] For details, see Figure 1 , Figure 1 This is an exploded schematic diagram of the structure of one of the implementation schemes of the window air conditioner in the implementation scheme of the present application. The window air conditioner includes: an inner heat exchanger 1, an outer heat exchanger 2, an inner fan 3, an outer fan 4, a water collection device 5 provided at the bottom of the outer heat exchanger 2, and a spray assembly 6 connected to the water collection device 5, and a control assembly 7. The control assembly 7 is communicated with the inner fan 3, the outer fan 4 and the spray assembly 6 respectively.

[0057] Among them, the inner heat exchanger 1 and the outer heat exchanger 2 are connected with the refrigerant, and the inner fan 3 is arranged on one side of the inner heat exchanger 1. The inner fan 3 is used to blow the heat exchange of the inner heat exchanger 1 to the air outlet of the window air conditioner, assisting the inner heat exchanger 1 to exchange heat and discharge air. It can be understood that the inner fan 3 may include a fan motor, and the outer fan 4 may also include a fan motor. The outer fan 4 is arranged on one side of the outer heat exchanger 2. The outer fan 4 is used to blow the air output from the air inlet of the window air conditioner to the outer heat exchanger 2, assisting the outer heat exchanger 2 to exchange heat and provide energy for the inner heat exchanger 1.

[0058] It can be understood that the window air conditioner also includes a shell, and the inner heat exchanger 1, the outer heat exchanger 2, the inner fan 3, the outer fan 4, and the water collection device 5 located at the bottom of the outer heat exchanger 2 are all located inside the shell, and the shell is provided with an air outlet and an air inlet.

[0059] Among them, the water collection device 5 can be a water collection trough provided on the shell corresponding to the bottom of the outer heat exchanger 2, or it can be a water collection box provided inside the shell. It can be understood that the shape and structure of the water collection trough or water collection box are not specifically limited in this application and can be designed according to actual needs.

[0060] Exemplarily, in order to ensure the water collection quality, the water collection tank can be set as a trumpet-shaped opening and a filter can be set on the opening to filter large particulate matter to avoid clogging the spray assembly 6.

[0061] In one embodiment of the present application, the water collection device 5 includes a water collection tank, a drain pipe connected to the water collection tank through a drain outlet, and an electrically controlled valve arranged in the drain pipe. The electrically controlled valve is communicatively connected to the control component 7. It can be understood that the control component 7 controls the switch of the electrically controlled valve based on the communication connection to control the water in the water collection tank to be discharged in time when self-cleaning is not required.

[0062] The spray assembly 6 may include at least one spray head and a spray kinetic energy device, such as a water pump located within the water collection tank, and a water pipe connecting the water pump and the spray head. It is understood that multiple spray heads may be provided, such as on one side of the inner fan 3, on one side of the outer heat exchanger 2, or on one side of the outer fan 4, and the specific location of the spray head is not specifically limited.

[0063] The control component 7 includes one or more processors; a memory; and one or more applications, wherein the one or more applications are stored in the memory and configured to be executed by the processor to implement the control method of the window air conditioner.

[0064] It can be understood that the window air conditioner also includes conventional window machine structures such as the compressor 8, that is, the number and type of structural devices contained in the window air conditioner do not affect the overall implementation of the technical solution in the embodiment of the present invention, and can all be regarded as equivalent replacements or derivatives of the technical solution required to be protected in the embodiment of the present invention.

[0065] The window air conditioner in the embodiment of the present invention is mainly used for: when the working mode of the window air conditioner is the heating mode, controlling the operating speed of the external fan 4 to drop to the target speed, and controlling the external heat exchanger 2 to produce condensation dripping; detecting the water volume parameter of the water collection device 5, wherein the water volume parameter includes any one of the water level value and the load weight of the water collection device 5; controlling the operation of the spray assembly 6 according to the water volume parameter, and controlling the external fan 4 and the internal fan 3 to adjust the speed.

[0066] Furthermore, in the scenario of the window air conditioner control method of the present application, the window air conditioner may be provided with a display device, or the window air conditioner may not be provided with a display device but may be communicatively connected to an external display device, the display device being used to output the results of the execution of the window air conditioner control method in the window air conditioner. The window air conditioner may access a backend database (the backend database may be in the local memory of the window air conditioner or may be provided in the cloud), which stores information related to the control of the window air conditioner.

[0067] Based on the above window air conditioner, an embodiment of a control method for the window air conditioner is proposed.

[0068] like Figure 2 FIG. 2 is a flow chart of an embodiment of a control method for a window air conditioner according to an embodiment of the present application. The control method for a window air conditioner includes steps S201-S203:

[0069] S201. When the working mode of the window air conditioner is the heating mode, the operating speed of the external fan is controlled to decrease to a target speed, and the external heat exchanger is controlled to generate condensation dripping.

[0070] Among them, the working mode of the window air conditioner can include a cooling mode and a heating mode. It can be understood that the heating mode can be determined by obtaining the working state of the window air conditioner, or by detecting the refrigerant flow direction of the compressor.

[0071] The target speed may be preset as the minimum speed of the external fan, or the minimum speed corresponding to the window air conditioner heating mode. It is understandable that the target speed may include multiple target speeds. By adjusting the external fan to different target speeds according to the preset adjustment logic, the condensation dripping of the external heat exchanger is controlled. This application does not make specific limitations, and is illustrative:

[0072] In one embodiment of the present application, the target speed is the preset minimum speed of the external fan, and the window air conditioner obtains the current working mode. When it is detected that the working mode is the heating mode, the external fan is controlled to reduce the speed to the preset minimum speed. By reducing the speed of the external fan, the thermal efficiency of the external heat exchanger is extremely low, which is far lower than the saturation temperature corresponding to the wet air under the current pressure. Therefore, the moisture in the air will condense on the fins of the external heat exchanger and liquefy to control the external heat exchanger to produce condensation dripping. When frost is detected on the outdoor heat exchanger, the external fan is controlled to increase the speed, and the cycle is implemented to control the operating speed of the external fan to drop to the target speed, so as to control the external heat exchanger to produce condensation dripping.

[0073] In another embodiment of the present application, the target speed includes a minimum speed and a maximum speed of the external fan. The window air conditioner obtains the current working mode. When it detects that the working mode is heating mode, the external fan is controlled to reduce its speed to a preset minimum speed. By reducing the external fan speed, the thermal efficiency of the external heat exchanger is extremely low, far below the saturation temperature of moist air at the current pressure. As a result, moisture in the air condenses and liquefies on the fins of the external heat exchanger, thereby controlling the generation of condensation on the external heat exchanger. As the evaporation temperature decreases, the condensation condensed on the evaporator condenses into a frost layer. Over time, the frost layer becomes thicker. When defrosting conditions are met, the external fan is increased to the maximum speed to defrost, quickly melting the frost on the external heat exchanger and generating a large amount of defrost water, thereby controlling the generation of condensation dripping from the external heat exchanger. This defrost water flows along the chassis and is collected by a specially designed groove structure on the chassis. It is understood that meeting the defrost conditions may include the frost formation duration reaching a preset duration or the frost layer thickness reaching a preset thickness.

[0074] It is further understood that the window air conditioner can control the operating speed of the external fan to decrease to the target speed upon detecting that the heating mode operation time has reached a preset time; or control the operating speed of the external fan to decrease to the target speed when the temperature difference between the indoor environment and the set environment is less than a preset temperature difference, so as to ensure indoor comfort.

[0075] S202: Detect water volume parameters of the water collection device.

[0076] Among them, the water volume parameter includes any one of the water level value and the load weight of the water collection device; it can be understood that the water level parameter can be detected by a water level monitoring sensor arranged on the side wall of the water collection tank of the water collection device, and the load weight of the water collection device can be detected by a gravity detection sensor arranged at the bottom of the water collection tank of the water collection device.

[0077] Specifically, the window air conditioner can control the external fan to reduce to the target speed and run for a preset time period before performing detection and acquisition according to a preset detection frequency.

[0078] S203: Control the operation of the spray assembly according to the water volume parameter, and control the external fan and the internal fan to adjust the rotation speed.

[0079] Wherein, when the spray assembly is in operation, that is, the spray head of the spray assembly sprays water mist, it can be understood that this is achieved by controlling the water pump of the spray assembly to operate through the control assembly.

[0080] Specifically, after the window air conditioner controls the operation of the spray assembly according to the water volume control parameter, it controls the external fan and the internal fan to adjust the speed. For example, the external fan and the internal fan are controlled to operate at their respective maximum speeds.

[0081] Further, based on the above implementation scheme, see Figure 3 , Figure 3 A flow chart of one implementation method for adjusting the outdoor fan to a target speed in the control method of the window air conditioner provided in an embodiment of the present application includes steps S301-S303:

[0082] S301: When it is detected that the working mode of the window air conditioner is a heating mode, obtain the indoor ambient temperature.

[0083] The indoor ambient temperature, that is, the temperature of the environment at the air outlet of the window air conditioner, can be detected by a temperature sensor that is communicatively connected to the window air conditioner.

[0084] Specifically, when the window air conditioner detects that the window air conditioner is in the heating working mode, the indoor ambient temperature is acquired according to a preset temperature acquisition frequency.

[0085] S302: Calculate the temperature difference between the indoor ambient temperature and the set temperature corresponding to the heating mode.

[0086] The set temperature is, that is, a user-set temperature corresponding to the heating mode or a preset temperature corresponding to the heating mode.

[0087] Furthermore, when an indoor ambient temperature is collected, the temperature difference between the indoor ambient temperature and the set temperature is calculated, and the temperature difference is compared with the preset temperature difference threshold. If the temperature difference is not less than the preset temperature difference threshold, it means that the temperature difference between the indoor ambient temperature and the set temperature is large, then the currently collected indoor ambient temperature and the calculated temperature difference are discarded, and the indoor ambient temperature is collected again to calculate the temperature difference.

[0088] S303: If the temperature difference is less than a preset temperature difference threshold, the operating speed of the external fan is controlled to decrease to a target speed, and the external heat exchanger is controlled to generate condensation dripping.

[0089] Furthermore, if the detected temperature difference is less than the preset temperature difference threshold, it means that the temperature difference between the indoor ambient temperature and the set temperature is small, that is, the indoor ambient temperature has reached the ideal state for heating. At this time, the operating speed of the external fan is controlled to drop to the target speed to avoid reducing the external fan speed when the indoor ambient temperature has not reached the set temperature, resulting in a decrease in the indoor ambient temperature regulation performance, thereby avoiding affecting the indoor environmental comfort.

[0090] Further, based on the above implementation scheme, see Figure 4 , Figure 4 A flow chart of another embodiment of the control method for a window air conditioner provided in an embodiment of the present application includes steps S401-S406:

[0091] S401: When the working mode of the window air conditioner is the heating mode, the operating speed of the external fan is controlled to decrease to a target speed, and the external heat exchanger is controlled to generate condensation dripping.

[0092] The specific implementation of step S401 can be found in any of the above implementations.

[0093] S402, obtaining a new indoor ambient temperature;

[0094] The new indoor ambient temperature is the re-acquired temperature of the environment corresponding to the air outlet of the window air conditioner. It is understandable that the indoor ambient temperature can be detected by a temperature sensor that is communicatively connected to the window air conditioner.

[0095] Specifically, after the window air conditioner controls the operating speed of the external fan to drop to the target speed, it collects and obtains the indoor ambient temperature according to a preset temperature collection frequency.

[0096] S403: If the temperature difference between the set temperature corresponding to the heating mode and the new indoor ambient temperature is greater than a preset temperature difference threshold, the operating speed of the outdoor fan is corrected according to a preset correction coefficient.

[0097] The preset correction coefficient may be a preset correction speed value, a preset correction percentage (speed), etc.

[0098] Specifically, after reacquiring the indoor ambient temperature, the window air conditioner calculates the temperature difference between the set temperature and the indoor ambient temperature. When it is detected that the temperature difference between the set temperature and the indoor ambient temperature is greater than a preset temperature difference threshold, it indicates that the indoor comfort level is reduced. At this time, the operating speed of the external fan is corrected according to the preset correction coefficient to appropriately increase the speed of the external fan, thereby enhancing the heat exchange effect of the inner heat exchanger and the outer heat exchanger.

[0099] It is understood that the present application does not make any specific limitation on the method of determining the preset correction coefficient, but for example:

[0100] In one embodiment of the present application, the preset correction coefficient is a fixed preset percentage. If the temperature difference between the set temperature corresponding to the heating mode and the indoor ambient temperature is greater than the preset temperature difference threshold, the operating speed of the external fan is controlled to increase by the preset percentage speed.

[0101] In one embodiment of the present application, there are multiple preset correction coefficients corresponding to different temperature differences. If the temperature difference between the set temperature corresponding to the heating mode and the indoor ambient temperature is greater than the preset temperature difference threshold, the preset correction coefficient corresponding to the temperature difference is obtained by searching the mapping table corresponding to the temperature difference and the correction coefficient, and the operating speed of the external fan is further corrected according to the preset correction coefficient.

[0102] S404: Control the external fan to operate at the corrected operating speed for a preset period of time and then resume operation at the target speed.

[0103] Specifically, after the window air conditioner controls the outdoor fan to operate at the corrected operating speed for a preset period of time, the outdoor fan is controlled to return to the target speed. It is understood that the preset time period can be preset based on the power of the window air conditioner, with a shorter preset time period for a higher power frequency and a longer preset time period for a lower power frequency. This ensures that after the window air conditioner controls the outdoor fan to operate at the corrected operating speed for the preset period of time, the temperature difference between the indoor ambient temperature and the set temperature is less than a preset temperature difference threshold. The outdoor fan is then further controlled to return to the target speed to control the generation of condensation dripping on the outer heat exchanger.

[0104] S405: Detect the water volume parameters of the water collection device.

[0105] The water volume parameter includes any one of a water level value and a load weight of the water collection device.

[0106] S406: Control the operation of the spray assembly according to the water volume parameter, and control the external fan and the internal fan to adjust their rotation speeds.

[0107] The specific implementation of steps S405-S406 can be found in any of the above implementation schemes.

[0108] Further, based on the above implementation scheme, see Figure 5 , Figure 5 A flow chart of one implementation scheme for adjusting and controlling the window air conditioner according to the water volume parameter in the control method of the window air conditioner provided in an embodiment of the present application includes steps S501-S502:

[0109] S501: If the water volume parameter is greater than a preset water volume parameter threshold, control the spray assembly to operate.

[0110] Among them, the water volume parameter includes any one of the water level value and the load weight of the water collection device; it can be understood that the water volume parameter threshold corresponding to the quantity parameter can be the water level threshold, the load weight threshold, etc.

[0111] Specifically, after the window air conditioner detects the water volume parameter of the water collection device, it compares the water volume parameter with the preset water volume parameter threshold. If the water volume parameter is greater than the preset water volume parameter threshold, it means that the water collection volume in the water collection device has reached the level that can meet the self-cleaning water volume requirement, and the spray component is controlled to operate and spray.

[0112] S502: When it is detected that the operation time of the spray assembly reaches a preset time, the inner fan is controlled to operate at a preset maximum speed, and the outer fan is controlled to operate at a preset maximum speed.

[0113] Furthermore, when it is detected that the spray component has been running for a preset time, the interior of the window air conditioner is fully filled with water mist, which is adsorbed on the inner heat exchanger, the outer heat exchanger, the inner fan, the outer fan, the filter at the air inlet and other structures. These water mists slowly gather into water droplets. At this time, by controlling the inner fan to run at a preset maximum speed and controlling the outer fan to run at a preset maximum speed, the inner heat exchanger, the outer heat exchanger, the inner fan, the outer fan and the filter can be flushed to achieve self-cleaning.

[0114] It can be understood that in some other embodiments of the present application, if the water volume parameter is less than or equal to the preset water volume parameter threshold, it means that the water collection volume in the water collection device does not meet the self-cleaning water volume requirement, and the spray assembly is controlled to remain in a stopped state, and the external fan and the internal fan are controlled to maintain the speed and not perform self-cleaning, thereby ensuring the quality of self-cleaning.

[0115] Further, based on the above implementation scheme, see Figure 6 , Figure 6 A flowchart of another embodiment of the control method of a window air conditioner provided in an embodiment of the present application includes steps S601-S605:

[0116] S601: When the working mode of the window air conditioner is the heating mode, the operating speed of the external fan is controlled to decrease to a target speed, and the external heat exchanger is controlled to generate condensation dripping.

[0117] S602: Detect water volume parameters of the water collection device.

[0118] The water volume parameter includes any one of a water level value and a load weight of the water collection device; the specific implementation scheme of steps S601-S602 can be found in any of the above implementation schemes.

[0119] S603: Obtain the historical operating time of the spray assembly.

[0120] The historical operation time is the time when the spray assembly was last started and operated.

[0121] Specifically, the window air conditioner detects the water volume parameter of the water collection device and obtains the historical operating time of the spray assembly when the water volume difference between the water volume parameter and a preset water volume parameter threshold is less than the preset water volume difference.

[0122] S604. If the target time interval between the historical operating time and the current time is less than or equal to the preset time interval, the water collection device is controlled to drain water according to the target time interval and the target water parameter difference between the water parameter and the preset water parameter threshold.

[0123] Furthermore, after obtaining the historical operating time, the window air conditioner calculates the target time interval between the historical operating time and the current time. When the target time interval is less than or equal to the preset time interval, it means that the interior of the window air conditioner is relatively clean. Therefore, based on the target time interval and the target water parameter difference between the water parameter and the preset water parameter threshold, the water collection device is controlled to drain water to avoid the water parameter triggering the operation of the spray component, resulting in unreasonable self-cleaning control.

[0124] It can be understood that, based on the target time interval and the target water parameter difference between the water parameter and the preset water parameter threshold, the water collection device is controlled to drain water. The specific implementation method is not specifically limited in this application, and is exemplified as follows:

[0125] (1) calculating a target water parameter difference between the water parameter and the preset water parameter threshold;

[0126] (2) searching a preset mapping table corresponding to a time interval and a water volume parameter difference, and obtaining a target drainage time corresponding to the target water volume parameter difference and the target time interval;

[0127] (3) Control the drain outlet of the water collection device to open and continue the target drainage time.

[0128] Specifically, controlling the drain outlet of the water collection device to open and maintain the target drainage time can be achieved by controlling the electric control valve provided at the drain outlet of the water collection device to open for the target drainage time by a control component.

[0129] S605: Control the operation of the spray assembly according to the water volume parameter, and control the external fan and the internal fan to adjust their rotation speeds.

[0130] The specific implementation of step S605 is shown in the above implementation scheme.

[0131] Specifically, in another embodiment of the present application, after step S603, that is, after obtaining the historical operating time, the window air conditioner calculates the target time interval between the historical operating time and the current time. If the target time interval between the historical operating time and the current time is greater than the preset time interval, the spray assembly is controlled to operate according to the water volume parameter, and the external fan and the internal fan are controlled to adjust the speed.

[0132] Further, based on the above implementation scheme, see Figure 7 , Figure 7 A flow chart of one implementation scheme for adjusting and controlling the window air conditioner according to the water volume parameter in the control method of the embodiment of the present application includes steps S701-S703:

[0133] S701: When the working mode of the window air conditioner is the heating mode, the operating speed of the external fan is controlled to decrease to a target speed, and the external heat exchanger is controlled to generate condensation dripping.

[0134] S702: Detect the water volume parameters of the water collection device.

[0135] Wherein, the water volume parameter includes any one of a water level value and a load weight of a water collection device;

[0136] S703: Control the operation of the spray assembly according to the water volume parameter, and control the external fan and the internal fan to adjust their rotation speeds.

[0137] The specific implementation of steps S701-S7603 may refer to any of the above implementation plans.

[0138] S704: When it is detected that the operation time of the spray assembly reaches a preset time, the spray assembly is controlled to stop; the air outlet opening of the window air conditioner is controlled to be adjusted to a preset minimum opening, and the air inlet opening of the window air conditioner is adjusted to a preset minimum opening;

[0139] Specifically, after controlling the operation of the spray assembly, the window air conditioner detects the operating time of the spray assembly. When the operating time of the spray assembly reaches a preset time, the inner heat exchanger, outer heat exchanger, inner fan, outer fan, and filter are flushed. At this time, the air outlet of the window air conditioner is controlled to open to a preset minimum opening, and the air inlet of the window air conditioner is also adjusted to a preset minimum opening to increase the internal temperature of the window air conditioner, dry the interior of the window air conditioner, ensure dryness, and prevent the growth of bacteria.

[0140] S705: Obtaining the ambient humidity inside the window air conditioner;

[0141] Furthermore, when the spray assembly is controlled to stop; and the air outlet opening of the window air conditioner is controlled to be adjusted to a preset minimum opening, after the air inlet opening of the window air conditioner is adjusted to the preset minimum opening, the ambient humidity inside the window air conditioner is obtained according to the preset humidity detection frequency.

[0142] S706: When it is detected that the ambient humidity is less than a preset humidity threshold, the air outlet opening and the air inlet opening of the window air conditioner are controlled to return to the openings before adjustment.

[0143] Specifically, when it is detected that the ambient humidity is less than a preset humidity threshold, indicating that the humidity inside the window air conditioner is low and is less likely to cause mold and bacteria, the window air conditioner's outlet and inlet openings are controlled to return to their pre-adjustment openings. The window air conditioner is controlled to operate normally for heating.

[0144] An embodiment of the present application provides a control method for a window air conditioner, which is applied to a window air conditioner. The window air conditioner includes an outer heat exchanger, an inner fan, an outer fan, a water collection device provided at the bottom of the outer heat exchanger, and a spray assembly connected to the water collection device. The method includes: when the working mode of the window air conditioner is a heating mode, controlling the operating speed of the outer fan to drop to a target speed, and controlling the outer heat exchanger to produce condensation dripping; detecting a water volume parameter of the water collection device, wherein the water volume parameter includes any one of a water level value and a load weight of the water collection device; controlling the operation of the spray assembly according to the water volume parameter, and controlling the outer fan and the inner fan to adjust the speed. The present application reduces the operating speed of the external fan to the target speed when the window air conditioner heating mode is detected, thereby reducing the heat exchange efficiency of the external heat exchanger. When the evaporation temperature is very low, much lower than the saturation temperature of the wet air under the current pressure, the moisture in the air will condense on the fins of the indoor evaporator and liquefy, thereby generating condensation and falling into the water collection device provided at the bottom of the external heat exchanger. The water volume parameters of the water collection device are further detected, and the water collection volume of the water collection device is detected. The operation of the spray assembly is controlled according to the water volume parameters, and the operation of the external fan and the internal fan are controlled. The speed is adjusted, that is, when it is detected that the amount of collected water is large enough to meet the self-cleaning control, the spray component is controlled to operate, and the spray component atomizes the water in the water collection device to form water mist. As more and more water mist is generated, it is adsorbed on the inner heat exchanger, outer heat exchanger, fan, and filter inside the window air conditioner. These water mists slowly gather into water droplets, further controlling the operation of the inner and outer fans to flush the inner heat exchanger, outer heat exchanger, fan, and filter, thereby realizing self-cleaning control of the window air conditioner. The entire process is realized in heating mode to ensure user comfort.
