Description

Technical Field

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

[0002] With social development and the continuous improvement of people's living standards, various air conditioning devices have become an indispensable electrical appliance in people's daily lives. These devices help people reach a comfortable temperature when the ambient temperature is too high or too low. Currently, air conditioning devices mainly include various types of air conditioners and fans.

[0003] Air conditioners can be divided into integrated air conditioners and split air conditioners. Split air conditioners include an indoor unit and an outdoor unit. Due to the increasing popularity of integrated home décor, people's requirements for air conditioner indoor units are also gradually rising. They not only need a high-quality appearance and superior performance, but also must meet the needs of home decoration. Built-in air conditioner indoor units not only have the functions of a regular air conditioner indoor unit, but also blend seamlessly with the style of the cabinetry. Embedding the air conditioner indoor unit into the cabinetry creates a unified and aesthetically pleasing look.

[0004] When using recessed indoor units, the air intake method similar to that of traditional wall-mounted air conditioners is not suitable. Traditional wall-mounted air conditioners typically draw air in through a top-mounted vent. However, once the indoor unit is recessed into a cabinet, the top is obstructed, affecting airflow. Furthermore, reduced airflow can prevent the indoor heat exchanger from fully exchanging heat, leading to icing and hindering its normal operation. Summary of the Invention

[0005] One objective of this invention is to adjust the rotation angle of the baffle plate according to the coil temperature of the front and rear parts of the indoor heat exchanger, so as to reasonably distribute the air volume of the front and rear parts of the indoor heat exchanger and improve the heat exchange efficiency.

[0006] A further objective of this invention is to increase the overall air intake volume and prevent the indoor heat exchanger from icing due to insufficient air volume.

[0007] Specifically, the present invention provides a control method for an air conditioner, wherein the air conditioner includes: a housing having an indoor heat exchanger disposed inside; an air inlet disposed on the upper front side of the housing and an air outlet disposed on the lower side; and a baffle plate rotatably disposed at the air inlet and located inside the housing, the baffle plate dividing the interior of the housing into a first channel at the rear and a second channel at the front, a portion of the indoor heat exchanger being located in the first channel and another portion being located in the second channel, and the method includes: receiving a trigger signal for the air conditioner to be turned on; controlling the baffle plate to operate in a horizontal initial posture for a preset time; acquiring the temperature of a first coil of the indoor heat exchanger in the first channel and the temperature of a second coil of the indoor heat exchanger in the second channel; determining a first rotation angle of the baffle plate based on the first coil temperature and a second rotation angle of the baffle plate based on the second coil temperature; and adjusting the actual rotation angle of the baffle plate based on the first rotation angle and the second rotation angle.

[0008] Optionally, the step of adjusting the actual rotation angle of the baffle plate according to the first rotation angle and the second rotation angle includes: determining whether the absolute value of the sum of the first rotation angle and the second rotation angle is less than or equal to the minimum rotation angle; and if so, controlling the baffle plate to maintain its initial posture.

[0009] Optionally, if the absolute value of the sum of the first rotation angle and the second rotation angle is greater than the minimum rotation angle, determine whether the sum of the first rotation angle and the second rotation angle is greater than or equal to the maximum upward angle; and if so, control the wind deflector to rotate upward to the maximum upward angle.

[0010] Optionally, if the sum of the first rotation angle and the second rotation angle is less than the maximum upward angle, determine whether the sum of the first rotation angle and the second rotation angle is less than or equal to the maximum downward angle; and if so, control the wind deflector to rotate downward to the maximum downward angle.

[0011] Optionally, if the sum of the first rotation angle and the second rotation angle is greater than the maximum downward angle, the wind deflector is controlled to rotate to the sum of the first rotation angle and the second rotation angle.

[0012] Optionally, the steps of determining the first rotation angle of the baffle plate based on the first coil temperature and the second rotation angle of the baffle plate based on the second coil temperature include: querying a preset mapping table to match the first rotation angle corresponding to the first coil temperature and matching the second rotation angle corresponding to the second coil temperature, wherein the mapping table stores rotation angles corresponding to different coil temperatures in advance, and the baffle plate rotates upward when the rotation angle is greater than 0, and rotates downward when the rotation angle is less than 0.

[0013] Optionally, the indoor heat exchanger is segmented and includes a front heat exchanger, a middle heat exchanger and a rear heat exchanger from front to back. The air inlet of the first channel is higher than the air inlet of the second channel, and the front heat exchanger and the middle heat exchanger are located in the second channel, while the rear heat exchanger is located in the first channel.

[0014] Optionally, the steps of obtaining the temperature of the first coil of the indoor heat exchanger in the first channel and the temperature of the second coil of the indoor heat exchanger in the second channel include: detecting the temperature of the first coil using a first temperature sensor installed at the downstream heat exchanger; and detecting the temperature of the second coil using a second temperature sensor installed at the connection between the upstream heat exchanger and the midstream heat exchanger.

[0015] According to another aspect of the present invention, an air conditioner is also provided, comprising: a controller, the controller including a memory and a processor, wherein the memory stores a machine-executable program, which, when executed by the processor, implements the control method of the air conditioner described above.

[0016] According to another aspect of the present invention, a machine-readable storage medium is also provided, on which a machine-executable program is stored, which, when executed by a processor, implements the control method of the air conditioner described above.

[0017] The air conditioner control method, air conditioner, and machine-readable storage medium of the present invention receive a trigger signal for the air conditioner to turn on, control the baffle plate to operate in a horizontal initial posture for a preset time, obtain the temperature of the first coil of the indoor heat exchanger in the first channel and the temperature of the second coil of the indoor heat exchanger in the second channel, determine the first rotation angle of the baffle plate based on the first coil temperature, determine the second rotation angle of the baffle plate based on the second coil temperature, and adjust the actual rotation angle of the baffle plate based on the first and second rotation angles. This allows for adjustment of the rotation angle of the baffle plate according to the coil temperatures of the front and rear parts of the indoor heat exchanger, rationally distributing the airflow in the front and rear parts of the indoor heat exchanger, improving heat exchange efficiency, ensuring the working effect of the air conditioner, and enhancing the user experience.

[0018] Furthermore, the air conditioner control method, air conditioner, and machine-readable storage medium of the present invention, when the absolute value of the sum of the first rotation angle and the second rotation angle is less than or equal to the minimum rotation angle, control the baffle plate to maintain its initial posture; when the absolute value of the sum of the first rotation angle and the second rotation angle is greater than the minimum rotation angle, and the sum of the first rotation angle and the second rotation angle is greater than or equal to the maximum upward angle, control the baffle plate to rotate upward to the maximum upward angle; when the sum of the first rotation angle and the second rotation angle is less than the maximum upward angle, and the sum of the first rotation angle and the second rotation angle is less than or equal to the maximum downward angle, control the baffle plate to rotate downward to the maximum downward angle; when the sum of the first rotation angle and the second rotation angle is greater than the maximum downward angle, control the baffle plate to rotate to the sum of the first rotation angle and the second rotation angle, can reasonably distribute the air volume of the front and rear parts of the indoor heat exchanger, thereby increasing the overall air intake volume, avoiding icing of the indoor heat exchanger due to insufficient air volume, and improving the working reliability of the indoor heat exchanger.

[0027] This embodiment first provides a control method for an air conditioner, which can adjust the rotation angle of the baffle plate according to the coil temperature of the front and rear parts of the indoor heat exchanger, reasonably distribute the air volume of the front and rear parts of the indoor heat exchanger, improve heat exchange efficiency, ensure the working effect of the air conditioner, and enhance the user experience. Figure 1 This is a schematic diagram of an air conditioner control method according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of an air conditioner 100 according to an embodiment of the present invention. Figure 3 This is a side sectional view of an air conditioner 100 according to an embodiment of the present invention. Figure 1 As shown, the control method for this air conditioner may include the following steps:

[0028] Step S102: Receive the trigger signal for the air conditioner 100 to be turned on;

[0029] Step S104: Control the windbreak plate 123 to run in a horizontal initial posture for a preset time;

[0030] Step S106: Obtain the first coil temperature of the indoor heat exchanger 111 in the first channel 115 and the second coil temperature of the indoor heat exchanger 111 in the second channel 116.

[0031] Step S108: Determine the first rotation angle of the baffle plate 123 based on the temperature of the first coil, and determine the second rotation angle of the baffle plate 123 based on the temperature of the second coil; and

[0032] Step S110: Adjust the actual rotation angle of the windbreak plate 123 according to the first rotation angle and the second rotation angle.

[0033] In the above steps, step S102 receives a trigger signal for the air conditioner to be turned on. In one specific embodiment, the trigger signal can be received from the air conditioner's display device, voice device, remote control, or a mobile terminal bound to the air conditioner. The mobile terminal can be a portable smart device, such as a smartphone or tablet.

[0034] like Figure 2 and Figure 3 As shown, the air conditioner 100 may include: a housing 110, in which an indoor heat exchanger 111 is disposed, an air inlet 121 is disposed on the upper front side of the housing 110, and an air outlet 122 is disposed on the lower side; and a baffle plate 123, which is rotatably disposed at the air inlet 121 and located inside the housing 110. The baffle plate 123 divides the interior of the housing 110 into a first channel 115 at the rear and a second channel 116 at the front. Part of the indoor heat exchanger 111 is located in the first channel 115 and the other part is located in the second channel 116.

[0035] The indoor heat exchanger 111 can be configured to exchange heat with the air entering the housing 110. Air can enter the housing 110 through the air inlet 121, and after heat exchange in the indoor heat exchanger 111, it can be delivered to the indoor environment through the air outlet 122. Specifically, when the air conditioner 100 is operating in cooling mode, the air heat exchanged by the indoor heat exchanger 111 is cold air, which can lower the ambient temperature after being delivered to the indoor environment. When the air conditioner 100 is operating in heating mode, the air heat exchanged by the indoor heat exchanger 111 is hot air, which can raise the ambient temperature after being delivered to the indoor environment.

[0036] After receiving the trigger signal for the air conditioner 100 to turn on, it can be considered that the air conditioner 100 has been turned on and is running. Specifically, according to the operating mode set by the user, the air conditioner 100 can operate in cooling mode, heating mode, or fan mode, etc. Step S104 controls the air baffle 123 to be in a horizontal initial position for a preset time. Regardless of the operating mode of the air conditioner 100, the air baffle 123 can be controlled to be in a horizontal initial position for a preset time.

[0037] After a preset time is reached, step S106 can be executed to obtain the first coil temperature of the indoor heat exchanger 111 in the first channel 115 and the second coil temperature of the indoor heat exchanger 111 in the second channel 116. In a specific embodiment, such as Figure 2 and Figure 3 As shown, the air inlet of the first channel 115 is higher than the air inlet of the second channel 116. In fact, the air inlets of both the first channel 115 and the second channel 116 are part of the air inlet 121. That is, some of the air entering the housing 110 from the air inlet 121 flows through the first channel 115, and some flows through the second channel 116. The indoor heat exchanger 111 is segmented and, from front to back, includes a front heat exchanger 117, a middle heat exchanger 118, and a rear heat exchanger 119. The front heat exchanger 117 and the middle heat exchanger 118 are located in the second channel 116, and the rear heat exchanger 119 is located in the first channel 115.

[0038] In a preferred embodiment, a first temperature sensor may be installed at the downstream heat exchanger 119, and a second temperature sensor may be installed at the connection between the upstream heat exchanger 117 and the mid-section heat exchanger 118. Step S106, which involves obtaining the first coil temperature of the indoor heat exchanger 111 in the first channel 115 and the second coil temperature of the indoor heat exchanger 111 in the second channel 116, may specifically include: detecting the first coil temperature using the first temperature sensor installed at the downstream heat exchanger 119; and detecting the second coil temperature using the second temperature sensor installed at the connection between the upstream heat exchanger 117 and the mid-section heat exchanger 118.

[0039] Step S108 determines the first rotation angle of the baffle plate 123 based on the first coil temperature and the second rotation angle of the baffle plate 123 based on the second coil temperature. The coil temperature reflects the heat exchange status of the air conditioner 100. For example, when the air conditioner 100 is running in cooling mode, if the heat exchange is poor, the coil temperature will be low. In a specific embodiment, step S108, which determines the first rotation angle of the baffle plate 123 based on the first coil temperature and the second rotation angle of the baffle plate 123 based on the second coil temperature, may specifically include: querying a preset mapping table to match the first rotation angle corresponding to the first coil temperature and the second rotation angle corresponding to the second coil temperature. The mapping table pre-stores rotation angles corresponding to different coil temperatures, and when the rotation angle is greater than 0, the baffle plate 123 rotates upward; when the rotation angle is less than 0, the baffle plate 123 rotates downward.

[0040] The actual data in the mapping table needs to be pre-calibrated through experiments. The mapping table between coil temperature and the rotation angle of the baffle plate 123 can be used to obtain the rotation angle corresponding to different coil temperatures. That is, considering only the front and middle evaporators, the baffle plate 123 needs to rotate at the second rotation angle; considering only the rear evaporator, the baffle plate 123 needs to rotate at the first rotation angle. This embodiment comprehensively considers both the first and second rotation angles to determine the actual rotation angle of the baffle plate 123, which is to execute step S110, adjusting the actual rotation angle of the baffle plate 123 according to the first and second rotation angles. The air conditioner control method of this embodiment can adjust the rotation angle of the baffle plate 123 according to the coil temperature of the sections before and after the indoor heat exchanger 111, reasonably allocate the airflow before and after the indoor heat exchanger 111, improve heat exchange efficiency, ensure the working effect of the air conditioner 100, and enhance the user experience.

[0041] In some optional embodiments, the air conditioner 100 can achieve higher technical effects through further optimization and configuration of the above steps. The following describes the control method of the air conditioner in this embodiment in detail with reference to an optional execution flow of this embodiment. This embodiment is only an example of the execution flow. In specific implementation, the execution order and operating conditions of some steps can be modified according to specific implementation requirements. Figure 4 This is a detailed flowchart of an air conditioner control method according to an embodiment of the present invention. The air conditioner control method includes the following steps:

[0042] Step S402: Receive the trigger signal for the air conditioner 100 to be turned on;

[0043] Step S404: Control the windbreak plate 123 to run in a horizontal initial posture for a preset time;

[0044] Step S406: Obtain the first coil temperature of the indoor heat exchanger 111 in the first channel 115 and the second coil temperature of the indoor heat exchanger 111 in the second channel 116.

[0045] Step S408: Query the preset mapping table to obtain the first rotation angle corresponding to the first coil temperature, and obtain the second rotation angle corresponding to the second coil temperature.

[0046] Step S410: Determine whether the absolute value of the sum of the first rotation angle and the second rotation angle is less than or equal to the minimum rotation angle. If yes, proceed to step S412; otherwise, proceed to step S414.

[0047] Step S412: Control the windbreak plate 123 to maintain its initial posture.

[0048] Step S414: Determine whether the sum of the first rotation angle and the second rotation angle is greater than or equal to the maximum upward angle. If yes, proceed to step S416; otherwise, proceed to step S418.

[0049] Step S416: Control the wind baffle 123 to rotate upward to the maximum upward angle;

[0050] Step S418: Determine whether the sum of the first rotation angle and the second rotation angle is less than or equal to the maximum downward angle. If yes, proceed to step S420; otherwise, proceed to step S422.

[0051] Step S420: Control the wind baffle 123 to rotate downwards to the maximum downward angle;

[0052] Step S422: Control the windbreak plate 123 to rotate to the sum of the first rotation angle and the second rotation angle.

[0053] In the above steps, steps S402 to S408 are executed first. The trigger signal for the air conditioner 100 to be turned on is received. The baffle plate 123 is controlled to run in a horizontal initial posture for a preset time. The first coil temperature of the indoor heat exchanger 111 in the first channel 115 and the second coil temperature of the indoor heat exchanger 111 in the second channel 116 are obtained. The preset mapping table is queried to match the first rotation angle corresponding to the first coil temperature and the second rotation angle corresponding to the second coil temperature.

[0054] Then, step S410 can be executed to determine whether the absolute value of the sum of the first rotation angle and the second rotation angle is less than or equal to the minimum rotation angle. If the result of step S410 is yes, that is, if the absolute value of the sum of the first rotation angle and the second rotation angle is less than or equal to the minimum rotation angle, then step S412 is executed to control the wind deflector 123 to maintain its initial posture. If the absolute value of the sum of the first rotation angle and the second rotation angle is less than or equal to the minimum rotation angle, it means that the required rotation angle is too small, and the wind deflector 123 does not need to rotate, and it can maintain its initial horizontal posture.

[0055] according to Figure 4 The execution sequence of the steps shown is as follows: if the judgment result of step S410 is negative, that is, if the absolute value of the sum of the first rotation angle and the second rotation angle is greater than the minimum rotation angle, then step S414 is executed to determine whether the sum of the first rotation angle and the second rotation angle is greater than or equal to the maximum upward angle. If the judgment result of step S414 is positive, that is, if the sum of the first rotation angle and the second rotation angle is greater than or equal to the maximum upward angle, then step S416 is executed to control the wind baffle 123 to rotate upward to the maximum upward angle.

[0056] Provided that the absolute value of the sum of the first rotation angle and the second rotation angle is greater than the minimum rotation angle, and the sum of the first rotation angle and the second rotation angle is greater than or equal to the maximum upward angle, it means that the wind baffle 123 needs to rotate upward, and needs to rotate upward to the maximum angle but cannot exceed it. It is sufficient to control the wind baffle 123 to rotate upward to the maximum upward angle.

[0057] according to Figure 4 The execution sequence of the steps shown is as follows: if the judgment result of step S414 is negative, that is, if the sum of the first rotation angle and the second rotation angle is less than the maximum upward angle, then step S418 is executed. In step S418, it is determined whether the sum of the first rotation angle and the second rotation angle is less than or equal to the maximum downward angle. If the judgment result of step S418 is positive, that is, if the sum of the first rotation angle and the second rotation angle is less than or equal to the maximum downward angle, then step S420 is executed to control the wind baffle 123 to rotate downward to the maximum downward angle.

[0058] Provided that the absolute value of the sum of the first rotation angle and the second rotation angle is greater than the minimum rotation angle, and the sum of the first rotation angle and the second rotation angle is less than or equal to the maximum downward angle, it means that the wind baffle 123 needs to rotate downward, and needs to rotate downward to the maximum angle but cannot exceed it. Controlling the wind baffle 123 to rotate downward to the maximum downward angle is sufficient.

[0059] according to Figure 4The execution sequence shown is as follows: if the judgment result of step S418 is negative (i.e., the sum of the first rotation angle and the second rotation angle is greater than the maximum downward angle), then step S422 is executed, controlling the wind baffle 123 to rotate to the sum of the first rotation angle and the second rotation angle. Provided that the absolute value of the sum of the first rotation angle and the second rotation angle is greater than the minimum rotation angle, and the sum of the first rotation angle and the second rotation angle is greater than the maximum downward angle, it indicates that the wind baffle 123 needs to rotate. Whether it rotates upward or downward depends on whether the sum of the first rotation angle and the second rotation angle is greater than 0 or less than 0. If the sum of the first rotation angle and the second rotation angle is greater than 0, then the wind baffle 123 rotates upward; if the sum of the first rotation angle and the second rotation angle is less than 0, then the wind baffle 123 rotates downward. The specific angle of rotation of the wind baffle 123 can be determined by rotating it to the sum of the first rotation angle and the second rotation angle.

[0060] The baffle plate 123 can rotate along its rear rotation axis. When the baffle plate 123 rotates upward to its maximum upward angle, the air intake of the rear heat exchanger 119 decreases, while the air intake of the front heat exchanger 117 and the middle heat exchanger 118 increases. When the baffle plate 123 rotates downward to its maximum downward angle, the air intake of the rear heat exchanger 119 increases, while the air intake of the front heat exchanger 117 and the middle heat exchanger 118 decreases.

[0061] It is important to emphasize that the front heat exchanger 117 and the middle heat exchanger 118 are closer to the air inlet 121 than the rear heat exchanger 119. Normally, most of the air entering the casing 110 through the air inlet 121 flows to the front heat exchanger 117 and the middle heat exchanger 118, while less air flows to the rear heat exchanger 119. This can lead to insufficient overall airflow, resulting in icing and other problems in the indoor heat exchanger 111. However, this embodiment addresses this by using a baffle plate 123 inside the casing 110 to regulate the airflow at the front and rear of the indoor heat exchanger 111. This allows the airflow into the first channel 115 to be stronger than that into the second channel 116, enabling more air to enter the first channel 115 through the air inlet 121 and exchange heat through the rear heat exchanger 119 within the first channel 115. This effectively solves the problem of icing in the indoor heat exchanger 111 caused by insufficient airflow.

[0062] In one specific embodiment, such as Figure 3 As shown, a fan 112 can be installed below the indoor heat exchanger 111, configured to blow the air that has been heated by the indoor heat exchanger 111 toward the air outlet 122. More specifically, as... Figure 3As shown, the front heat exchanger 117 can be set in a basically vertical position, the middle heat exchanger 118 can be set to gradually rise from front to back, and the rear heat exchanger 119 can be set to gradually lower from front to back, so that the space below where the fan 112 is housed is defined by the front heat exchanger 117, the middle heat exchanger 118 and the rear heat exchanger 119.

[0063] The air conditioner 100 in this embodiment specifically refers to the indoor unit of an air conditioner, and the air conditioner 100 in this embodiment can be embedded in a cabinet. Currently, the air intake method of traditional wall-mounted air conditioner indoor units is not suitable for embedded installation. This is because traditional wall-mounted air conditioner indoor units typically intake air through an air inlet at the top. After the indoor unit is embedded in a cabinet, the top will be blocked by the cabinet, affecting air intake. Furthermore, reduced air intake will cause the indoor heat exchanger of the air conditioner indoor unit to not exchange heat sufficiently, easily leading to icing and affecting the normal operation of the indoor heat exchanger.

[0064] The air conditioner 100 in this embodiment adopts a front air intake and front air outlet configuration, and uses a dual-channel design inside the casing 110. This allows the air entering the casing 110 through the air inlet 121 to be effectively guided to the rear heat exchanger 119, avoiding icing of the indoor heat exchanger 111 due to insufficient airflow. At the same time, it achieves front air intake and front air outlet, without being restricted by cabinets.

[0065] In summary, the air conditioner control method of this embodiment controls the baffle plate 123 to maintain its initial posture when the absolute value of the sum of the first rotation angle and the second rotation angle is less than or equal to the minimum rotation angle; controls the baffle plate 123 to rotate upward to the maximum upward angle when the absolute value of the sum of the first rotation angle and the second rotation angle is greater than the minimum rotation angle and the sum of the first rotation angle and the second rotation angle is greater than or equal to the maximum upward angle; controls the baffle plate 123 to rotate downward to the maximum downward angle when the sum of the first rotation angle and the second rotation angle is less than the maximum upward angle and the sum of the first rotation angle and the second rotation angle is less than or equal to the maximum downward angle; and controls the baffle plate 123 to rotate to the sum of the first rotation angle and the second rotation angle when the sum of the first rotation angle and the second rotation angle is greater than the maximum downward angle. This method can reasonably distribute the air volume in the front and rear parts of the indoor heat exchanger 111, thereby increasing the overall air intake volume, preventing the indoor heat exchanger 111 from icing due to insufficient air volume, and improving the working reliability of the indoor heat exchanger 111.

[0066] This embodiment also provides an air conditioner 100, which may include a controller 300. Figure 5 This is a schematic block diagram of an air conditioner controller 300 according to an embodiment of the present invention. Figure 5As shown, the controller 300 may include a processor 310 and a memory 320. The memory 320 stores a machine-executable program 321. When the machine-executable program 321 is executed by the processor 310, it is used to implement any of the above-mentioned air conditioner control methods.

[0067] Processor 310 can be a central processing unit (CPU), a digital processing unit, etc. Processor 310 sends and receives data via a communication interface. Memory 320 is used to store the machine-executable program 321 executed by processor 310. Memory 320 can be any medium capable of carrying or storing desired program code in the form of instructions or data structures that is accessible by a computer, or it can be a combination of multiple memories 320. The aforementioned machine-executable program 321 can be downloaded from a computer-readable storage medium to the appropriate computing / processing device or downloaded and installed to controller 300 via a network (e.g., the Internet, local area network, wide area network, and / or wireless network).

[0068] In this embodiment, the air conditioner 100 can adjust the rotation angle of the baffle plate 123 according to the coil temperature of the front and rear parts of the indoor heat exchanger 111, reasonably distribute the air volume of the front and rear parts of the indoor heat exchanger 111, improve heat exchange efficiency, ensure the working effect of the air conditioner 100, and improve the user experience; reasonably distribute the air volume of the front and rear parts of the indoor heat exchanger 111, thereby increasing the overall air intake volume, avoiding icing of the indoor heat exchanger 111 due to insufficient air volume, and improving the working reliability of the indoor heat exchanger 111.

[0069] This embodiment also provides a machine-readable storage medium 400. Figure 6 This is a schematic diagram of a machine-readable storage medium 400 according to an embodiment of the present invention. The machine-readable storage medium 400 stores a machine-executable program 321, which, when executed by a processor 310, implements the control method of an air conditioner according to any of the above embodiments.

[0070] The machine-readable storage medium 400 of this embodiment may be an electronic memory such as flash memory, EEPROM (Electrically Erasable Programmable Read-Only Memory), EPROM, hard disk, or ROM. The machine-readable storage medium 400 has storage space for a machine-executable program 321 for performing any of the method steps described above. These machine-executable programs 321 can be read from or written to one or more computer program products.
