Description

Technical Field

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

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

[0003] Air conditioners can be categorized into floor-standing, wall-mounted, and ceiling-mounted types based on their indoor unit installation method. Floor-standing air conditioner indoor units are mainly used in larger spaces such as living rooms, schools, and hospitals. Wall-mounted air conditioner indoor units are primarily used in smaller spaces such as bedrooms. Existing wall-mounted air conditioner indoor units often use a single air outlet and a single fan. When operating in cooling mode, this fails to address the discomfort caused by direct cold airflow; when operating in heating mode, the uneven cooling airflow results in a small heating outlet, poor heating efficiency, or the heating airflow not reaching the floor, leading to poor heat perception. In short, current adjustments to wall-mounted air conditioner indoor units are somewhat limited, resulting in lower operating efficiency and a less comfortable user experience. Summary of the Invention

[0004] One objective of this invention is to provide a variety of different air outlet modes by adjusting the opening and closing states of the upper and lower air outlets of the indoor unit of a wall-mounted air conditioner.

[0005] A further objective of this invention is to improve the operating efficiency of the indoor unit of a wall-mounted air conditioner and enhance the user's comfort experience.

[0006] Specifically, the present invention provides a control method for an indoor unit of a wall-mounted air conditioner, wherein a first air outlet is provided at the upper front end of the wall-mounted air conditioner indoor unit, and a second air outlet is provided at the lower front end of the wall-mounted air conditioner indoor unit. The method includes: acquiring the operating mode and set temperature of the wall-mounted air conditioner indoor unit; detecting the indoor temperature of the indoor environment where the wall-mounted air conditioner indoor unit is located; determining the opening and closing states of the first air outlet and the second air outlet based on the operating mode, the set temperature, and the indoor temperature; and controlling the first air outlet and the second air outlet to operate according to the determined opening and closing states.

[0007] Optionally, the indoor unit of the wall-mounted air conditioner is equipped with a fan configured to deliver air to the first air outlet and / or the second air outlet. The fan also determines the opening and closing status of the first and second air outlets based on the operating mode, set temperature, and indoor temperature, and determines the operating status of the fan.

[0008] Optionally, the steps of determining the opening and closing status of the first and second air outlets and the operating status of the fan based on the operating mode, the set temperature and the indoor temperature include: determining whether the operating mode is a cooling mode; if so, calculating the first difference between the indoor temperature and the set temperature; determining whether the first difference is greater than or equal to a first preset value; if so, determining that the fan operates at a first speed and both the first and second air outlets are open.

[0009] Optionally, when the operating mode is cooling mode, and the first difference is greater than or equal to the second preset value and less than the first preset value, the fan is determined to operate at the second speed, and both the first air outlet and the second air outlet are opened, wherein the second speed is less than the first speed.

[0010] Optionally, when the operating mode is cooling mode, and the first difference is greater than or equal to the third preset value and less than the second preset value, the fan is determined to operate at the second speed, the first air outlet is opened, and the second air outlet is closed.

[0011] Optionally, when the operating mode is cooling mode, and the first difference is greater than or equal to 0 and less than the third preset value, the fan is determined to operate at the third speed, the first air outlet is opened, and the second air outlet is closed, wherein the third speed is less than the second speed.

[0012] Optionally, when the operating mode is heating mode, calculate the second difference between the set temperature and the indoor temperature; determine whether the second difference is greater than or equal to the first preset value; if so, determine that the fan operates at the first speed and both the first air outlet and the second air outlet are opened.

[0013] Optionally, when the operating mode is heating mode, and the second difference is greater than or equal to the second preset value and less than the first preset value, the fan is determined to operate at the second speed, and both the first air outlet and the second air outlet are opened.

[0014] Optionally, when the operating mode is heating mode, and the second difference is greater than or equal to the third preset value and less than the second preset value, the fan is determined to operate at the second speed, the first air outlet is closed, and the second air outlet is opened.

[0015] Optionally, when the operating mode is heating mode, and the second difference is greater than or equal to 0 and less than the third preset value, the fan is determined to operate at the third speed, the first air outlet is closed, and the second air outlet is opened.

[0016] According to another aspect of the present invention, a wall-mounted air conditioner indoor unit is also provided, comprising: a controller, the controller including a memory and a processor, wherein the memory stores a machine-executable program, and the machine-executable program, when executed by the processor, implements the control method of the wall-mounted air conditioner indoor unit as described above.

[0017] According to another aspect of the present invention, a machine-readable storage medium is also provided, on which a machine-executable program is stored, wherein the machine-executable program, when executed by a processor, implements the control method for the indoor unit of a wall-mounted air conditioner as described above.

[0018] The present invention discloses a control method for an indoor unit of a wall-mounted air conditioner, an indoor unit, and a storage medium. The method acquires the operating mode and set temperature of the indoor unit, detects the indoor temperature of the room where the indoor unit is located, determines the opening and closing states of the first and second air outlets based on the operating mode, set temperature, and indoor temperature, and controls the first and second air outlets to operate according to the determined opening and closing states. By adjusting the opening and closing states of the upper and lower air outlets of the indoor unit, various different air outlet modes can be provided to fully meet the user's needs.

[0019] Furthermore, the control method, indoor unit, and storage medium of the wall-mounted air conditioner indoor unit of the present invention determine the opening and closing states of the first and second air outlets and the operating state of the fan according to the operating mode, set temperature, and indoor temperature of the wall-mounted air conditioner indoor unit. This results in a better user experience in both cooling and heating modes, greatly improves the operating efficiency of the wall-mounted air conditioner indoor unit, effectively reduces noise and energy consumption, and enhances user comfort.

[0030] This embodiment first provides a control method for the indoor unit of a wall-mounted air conditioner, which can provide a variety of different air outlet modes by adjusting the opening and closing states of the upper and lower air outlets of the indoor unit, fully meeting the user's needs. Figure 1 This is a schematic diagram of a control method for an indoor unit of a wall-mounted air conditioner according to an embodiment of the present invention. Figure 1 As shown, the control method for the indoor unit of this wall-mounted air conditioner may include the following steps:

[0031] Step S102: Obtain the operating mode and set temperature of the indoor unit of the wall-mounted air conditioner;

[0032] Step S104: Detect the indoor temperature of the indoor environment where the indoor unit of the wall-mounted air conditioner is located;

[0033] Step S106: Determine the opening and closing status of the first air outlet and the second air outlet based on the operating mode, set temperature and indoor temperature.

[0034] Step S108: Control the first air outlet and the second air outlet to operate according to the determined opening and closing states.

[0035] It should be noted that, in this embodiment, the upper front end of the wall-mounted air conditioner indoor unit is provided with a first air outlet, and the lower front end of the wall-mounted air conditioner indoor unit is provided with a second air outlet. Regarding the operating mode and set temperature in step S102, users can generally set them through the display device, voice device, remote control, or a mobile terminal bound to the wall-mounted air conditioner indoor unit. The mobile terminal can be a portable smart device, such as a smartphone or tablet.

[0036] In one specific embodiment, the operating mode may include a cooling mode and a heating mode. Generally, in hot summers, users can set the operating mode to cooling mode, which lowers the indoor temperature by providing cooling capacity through the wall-mounted air conditioner's indoor unit; in cold winters, users can set the operating mode to heating mode, which raises the indoor temperature by providing heat through the wall-mounted air conditioner's indoor unit. In a preferred embodiment, the operating mode may further include silent mode, fan mode, emergency mode, anti-direct-blow mode, and defrost mode within the cooling and heating modes. The set temperature can be the temperature the user desires for the indoor environment.

[0037] Step S104 involves detecting the indoor temperature of the room where the wall-mounted air conditioner's indoor unit is located. The indoor temperature can generally be obtained using a temperature sensor. In one specific embodiment, a temperature sensor can be installed on the casing of the wall-mounted air conditioner's indoor unit to detect the indoor temperature. In a preferred embodiment, a temperature sensor can be installed on the wall diagonally opposite the indoor unit, which makes the detected indoor temperature more accurate and better reflects the true indoor temperature.

[0038] As mentioned earlier, the indoor unit of the wall-mounted air conditioner in this embodiment has a first air outlet and a second air outlet arranged vertically. The opening and closing states of the first air outlet and the second air outlet can be the same or different. Step S106 determines the opening and closing states of the first air outlet and the second air outlet based on the operating mode, the set temperature, and the indoor temperature, which allows for different combinations of opening and closing states of the first air outlet and the second air outlet. For example, both the first air outlet and the second air outlet can be open; or both the first air outlet and the second air outlet can be closed; or the first air outlet can be open and the second air outlet can be closed; or the first air outlet can be closed and the second air outlet can be open.

[0039] Generally, when the indoor unit of a wall-mounted air conditioner is operating in cooling mode, if the indoor temperature differs significantly from the set temperature, both the first and second air outlets can be opened to achieve a wraparound airflow effect, providing cooling capacity more quickly and in greater quantities, enhancing the cooling effect, and lowering the indoor temperature as soon as possible to make the user feel cool. If the indoor temperature differs slightly from the set temperature, the first air outlet can be opened while the second air outlet is closed, allowing the cooling airflow to blow horizontally from the first air outlet at the top, avoiding direct cold air blowing on people and achieving a more even distribution of cool air in the room.

[0040] When the indoor unit of a wall-mounted air conditioner is operating in heating mode, if there is a significant difference between the set temperature and the indoor temperature, both the first and second air outlets can be opened to achieve a top-to-bottom airflow effect. This provides heat more quickly and in greater quantities, enhancing the heating effect and raising the indoor temperature as soon as possible, making the user feel warm. Furthermore, because of the top-to-bottom airflow, the indoor temperature will be more even, resulting in greater user comfort. If the difference between the set temperature and the indoor temperature is small, the first air outlet can be closed while the second air outlet is open, allowing hot air to be blown directly from the lower second air outlet to the floor, achieving comfortable airflow.

[0041] Step S108 controls the first and second air outlets to operate according to the determined open / closed states. This ensures that the opening and closing states of the first and second air outlets of the wall-mounted air conditioner indoor unit are more consistent with actual conditions, better meeting user needs and improving user comfort. Specifically, when both the first and second air outlets are determined to be open, both can be controlled to be open. When the first air outlet is determined to be open and the second air outlet is closed, both can be controlled to be open and closed. When the first air outlet is determined to be closed and the second air outlet is open, both can be controlled to be closed and open. When both the first and second air outlets are determined to be closed, both can be controlled to be closed. Generally, when the wall-mounted air conditioner indoor unit is turned off, both the first and second air outlets can be controlled to be closed.

[0042] In summary, the control method for the indoor unit of the wall-mounted air conditioner in this embodiment acquires the operating mode and set temperature of the indoor unit, detects the indoor temperature of the room where the indoor unit is located, determines the opening and closing states of the first and second air outlets based on the operating mode, set temperature, and indoor temperature, and controls the first and second air outlets to operate according to the determined opening and closing states. By adjusting the opening and closing states of the upper and lower air outlets of the indoor unit, a variety of different air outlet modes can be provided to fully meet the user's needs.

[0043] In some optional embodiments, the wall-mounted air conditioner indoor unit can achieve higher technical effects through further optimization and configuration of the above steps. The following describes in detail the control method of the wall-mounted air conditioner indoor unit of this embodiment 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 2 This is a detailed flowchart of a control method for an indoor unit of a wall-mounted air conditioner according to an embodiment of the present invention. The control method for the indoor unit of the wall-mounted air conditioner includes the following steps:

[0044] Step S202: Obtain the operating mode and set temperature of the indoor unit of the wall-mounted air conditioner;

[0045] Step S204: Detect the indoor temperature of the indoor environment where the indoor unit of the wall-mounted air conditioner is located;

[0050] Step S214: Determine whether the first difference is greater than or equal to the second preset value and less than the first preset value. If yes, proceed to step S216; otherwise, proceed to step S218.

[0051] Step S216: Determine that the fan is running at the second speed, both the first and second air outlets are open, and then proceed to step S246.

[0052] Step S218: Determine whether the first difference is greater than or equal to the third preset value and less than the second preset value. If yes, proceed to step S220; otherwise, proceed to step S222.

[0053] Step S220: Determine that the fan is running at the second speed, the first air outlet is opened, the second air outlet is closed, and then proceed to step S246.

[0054] Step S222: The first difference is greater than or equal to 0 and less than the third preset value;

[0055] Step S224: Determine that the fan is running at the third speed, the first air outlet is opened, the second air outlet is closed, and then proceed to step S246.

[0056] Step S226, the operating mode is heating mode;

[0057] Step S228: Calculate the second difference between the set temperature and the indoor temperature;

[0058] Step S230: Determine whether the second difference is greater than or equal to the first preset value. If yes, proceed to step S232; otherwise, proceed to step S234.

[0059] Step S232: Determine that the fan is running at the first speed, and both the first and second air outlets are open, and then proceed to step S246.

[0060] Step S234: Determine whether the second difference is greater than or equal to the second preset value and less than the first preset value. If yes, proceed to step S236; otherwise, proceed to step S238.

[0061] Step S236: Determine that the fan is running at the second speed, both the first and second air outlets are open, and then proceed to step S246.

[0062] Step S238: Determine whether the second difference is greater than or equal to the third preset value and less than the second preset value. If yes, proceed to step S240; otherwise, proceed to step S242.

[0063] Step S240: Determine that the fan is running at the second speed, close the first air outlet, open the second air outlet, and execute step S246.

[0064] Step S242: The second difference is greater than or equal to 0 and less than the third preset value;

[0065] Step S244: Determine that the fan is running at the third speed, close the first air outlet, open the second air outlet, and execute step S246.

[0066] Step S246: Control the first air outlet, the second air outlet, and the fan to operate according to the determined state.

[0067] It should be noted that, in this embodiment, the upper front end of the wall-mounted air conditioner indoor unit is provided with a first air outlet, and the lower front end of the wall-mounted air conditioner indoor unit is provided with a second air outlet. The opening and closing states of the first air outlet and the second air outlet can be the same or different. Furthermore, a fan can be installed inside the wall-mounted air conditioner indoor unit, configured to deliver air to the first air outlet and / or the second air outlet.

[0068] In the above steps, steps S202 and S204 are first executed to obtain the operating mode and set temperature of the wall-mounted air conditioner indoor unit, and to detect the indoor temperature of the room where the wall-mounted air conditioner indoor unit is located. Specifically, the user can set the operating mode and set the temperature through the display device, voice device, remote control, or mobile terminal bound to the wall-mounted air conditioner indoor unit. The indoor temperature can generally be detected by a temperature sensor.

[0069] Then, step S206 can be executed to determine whether the operating mode is cooling mode. If the result of step S206 is yes, that is, if the operating mode is cooling mode, step S208 can be executed to calculate the first difference between the indoor temperature and the set temperature. Then, step S210 can be executed to determine whether the first difference is greater than or equal to the first preset value. If the result of step S210 is yes, that is, if the operating mode is cooling mode and the first difference is greater than or equal to the first preset value, step S212 can be executed to determine that the fan is running at the first speed and both the first air outlet and the second air outlet are open.

[0070] It should be noted that the first preset value can be a very high temperature value, and the first speed can also be a very high speed. The operating mode is cooling mode. If the first difference is greater than or equal to the first preset value, it indicates that it may be a hot summer day, with a large difference between the indoor temperature and the set temperature. This allows both the first and second air outlets to open, and the fan to run at a high first speed. This achieves a wraparound airflow effect while providing cooling more quickly and in greater quantities, enhancing the cooling effect and rapidly lowering the indoor temperature to make the user feel cool.

[0071] If the judgment result in step S210 is negative, that is, if the operating mode is cooling mode and the first difference is less than the first preset value, then step S214 is executed to determine whether the first difference is greater than or equal to the second preset value and less than the first preset value. If the judgment result in step S214 is positive, that is, if the operating mode is cooling mode and the first difference is greater than or equal to the second preset value and less than the first preset value, then step S216 is executed to determine that the fan operates at the second speed and both the first air outlet and the second air outlet are open.

[0072] The second speed is less than the first speed. The operating mode is cooling mode. The first difference is greater than or equal to the second preset value and less than the first preset value, which indicates that it may be a hot summer day and the indoor temperature is significantly different from the set temperature. This allows both the first and second air outlets to open and the fan to run at a moderate second speed, achieving a wraparound airflow effect. This not only cools the room quickly but also saves energy to some extent.

[0073] If the judgment result in step S214 is negative, that is, if the operating mode is cooling mode and the first difference is less than the second preset value, then step S218 is executed to determine whether the first difference is greater than or equal to the third preset value and less than the second preset value. If the judgment result in step S218 is positive, that is, if the operating mode is cooling mode and the first difference is greater than or equal to the third preset value and less than the second preset value, then step S220 is executed to determine that the fan operates at the second speed, the first air outlet is opened, and the second air outlet is closed.

[0074] The operating mode is cooling mode. The first difference is greater than or equal to the third preset value and less than the second preset value, which means that although it may be summer, the indoor temperature is relatively close to the set temperature. This allows the first air outlet to open and the second air outlet to close, and the fan to run at a moderate second speed. This allows the cooling airflow to blow out horizontally from the first air outlet above, avoiding direct cold air blowing on people and achieving uniform distribution of cool air in the room. It can also save energy to a certain extent.

[0075] Since the operating mode is cooling mode, which is typically hot summer days and the indoor temperature is higher than the set temperature, the first difference, which is the difference between the indoor temperature and the set temperature, can normally be assumed to be greater than or equal to 0. Therefore, if the judgment result in step S218 is negative, it can be directly determined that the first difference is greater than or equal to 0 and less than the third preset value, i.e., step S222 is executed, followed by step S224, which determines that the fan operates at the third speed, the first air outlet is opened, and the second air outlet is closed.

[0076] The third speed is less than the second speed. The operating mode is cooling mode. The first difference is greater than or equal to 0 and less than the third preset value, indicating that although it may be summer, the indoor temperature is very close to the set temperature. This allows the first air outlet to open and the second air outlet to close, and the fan to run at a very low third speed. This allows the cooling airflow to blow out horizontally from the first air outlet above, avoiding direct cold air blowing on people and achieving uniform distribution of cool air indoors, while also effectively saving energy.

[0077] In one specific embodiment, the operating mode may include a cooling mode and a heating mode. Therefore, if the determination result in step S206 is negative, i.e., the operating mode is not cooling mode, the operating mode can be determined to be heating mode, i.e., step S226 is executed. Then, steps S228 and S230 are executed to calculate the second difference between the set temperature and the indoor temperature, and to determine whether the second difference is greater than or equal to the first preset value. If the determination result in step S230 is positive, i.e., the operating mode is heating mode and the second difference is greater than or equal to the first preset value, step S232 is executed to determine that the fan operates at the first speed, and both the first air outlet and the second air outlet are open.

[0078] It should be noted that the operating mode is heating mode. If the second difference is greater than or equal to the first preset value, it indicates that it may be a cold winter day, and the set temperature differs significantly from the indoor temperature. This allows both the first and second air outlets to open, and the fan to operate at a high initial speed. This achieves a wraparound airflow effect while providing heat more quickly and in greater quantities, enhancing the heating effect and rapidly raising the indoor temperature to make users feel warm. Furthermore, because of the top and bottom airflow, the indoor temperature will be more even, enhancing user comfort.

[0079] If the judgment result in step S230 is negative, that is, if the operating mode is heating mode and the second difference is less than the first preset value, then step S234 is executed to determine whether the second difference is greater than or equal to the second preset value and less than the first preset value. If the judgment result in step S234 is positive, that is, if the operating mode is heating mode and the second difference is greater than or equal to the second preset value and less than the first preset value, then step S236 is executed to determine that the fan operates at the second speed and both the first air outlet and the second air outlet are open.

[0080] The operating mode is heating mode. If the second difference is greater than or equal to the second preset value and less than the first preset value, it indicates that it may be a cold winter and the set temperature is significantly different from the indoor temperature. This allows both the first and second air outlets to open and the fan to run at a moderate second speed, achieving a top-to-bottom circumferential air supply effect. This not only heats up quickly but also saves energy to a certain extent.

[0081] If the judgment result in step S234 is negative, that is, if the operating mode is heating mode and the second difference is less than the second preset value, then step S238 is executed to determine whether the second difference is greater than or equal to the third preset value and less than the second preset value. If the judgment result in step S238 is positive, that is, if the operating mode is heating mode and the second difference is greater than or equal to the third preset value and less than the second preset value, then step S240 is executed to determine that the fan operates at the second speed, the first air outlet is closed, and the second air outlet is opened.

[0082] The operating mode is heating mode. The second difference is greater than or equal to the third preset value and less than the second preset value. This means that although it may be winter, the set temperature is relatively close to the indoor temperature. This allows the first air outlet to close and the second air outlet to open. The fan can then run at a moderate second speed, so that hot air can be blown out from the second air outlet below and reach the floor directly, achieving comfortable air delivery and saving energy to a certain extent.

[0083] Since the operating mode is heating mode, which is generally a cold winter, the set temperature is higher than the indoor temperature. The second difference, representing the difference between the set temperature and the indoor temperature, can normally be assumed to be greater than or equal to 0. Therefore, if the judgment result in step S238 is negative, it can be directly determined that the second difference is greater than or equal to 0 and less than the third preset value, i.e., step S242 is executed, followed by step S244, determining that the fan operates at the third speed, the first air outlet is closed, and the second air outlet is opened.

[0084] The operating mode is heating mode. The second difference is greater than or equal to 0 and less than the third preset value, indicating that although it may be winter, the set temperature is very close to the indoor temperature. This allows the first air outlet to close and the second air outlet to open, and the fan to run at a very low third speed. This allows hot air to be blown out from the second air outlet below and directly to the floor, achieving comfortable air supply and effectively saving energy.

[0085] It should be noted that after determining the opening / closing status of the first and second air outlets and the operating status of the fan in steps S212, S216, S220, S224, S232, S236, S240, and S244, step S246 can be executed to control the first and second air outlets and the fan to operate according to the determined status. For example, if step S212 determines that the fan is operating at a first speed and both the first and second air outlets are open, then the fan can be controlled to operate at the first speed and both the first and second air outlets will be open.

[0086] The first, second, and third speeds decrease sequentially. In one specific embodiment, the first speed can be high speed, the second speed can be medium speed, and the third speed can be low speed. The first, second, and third preset values ​​decrease sequentially. In one specific embodiment, the first preset value can be 10, the second preset value can be 7, and the third preset value can be 4. If the indoor temperature is t and the set temperature is t1, the first difference Δt1 = t - t1 during cooling operation; and the second difference Δt2 = t1 - t during heating operation. Based on the above settings, a specific example is described below:

[0087] When the indoor unit of the wall-mounted air conditioner is running in cooling mode, if Δt1≥10, the fan runs at high speed and both the first and second air outlets are open; if 7≤Δt1<10, the fan runs at medium speed and both the first and second air outlets are open; if 4≤Δt1<7, the fan runs at medium speed, the first air outlet is open and the second air outlet is closed; if 0≤Δt1<4, the fan runs at low speed, the first air outlet is open and the second air outlet is closed.

[0088] When the indoor unit of the wall-mounted air conditioner is running in heating mode, if Δt2≥10, the fan runs at high speed and both the first and second air outlets are open; if 7≤Δt2<10, the fan runs at medium speed and both the first and second air outlets are open; if 4≤Δt2<7, the fan runs at medium speed, the first air outlet is closed and the second air outlet is open; if 0≤Δt2<4, the fan runs at low speed, the first air outlet is closed and the second air outlet is open.

[0089] It should be noted that the specific values ​​of the preset parameters mentioned above are merely illustrative examples and not intended to limit the invention. In other embodiments, different values ​​can be set according to actual conditions, but the magnitude relationships mentioned above must be satisfied. In this embodiment, the operating modes of the indoor unit of the wall-mounted air conditioner include cooling mode and heating mode. In other embodiments, the operating modes may also include: air supply mode, emergency mode, anti-direct-blow mode, defrost mode, etc.

[0090] Different controls can be implemented for the indoor unit of a wall-mounted air conditioner for operating modes other than cooling and heating. For example, when the indoor unit is operating in fan-only mode, the fan speed can be controlled to high, medium, low, or very low, with the first air outlet closed and the second air outlet open. When the indoor unit is operating in emergency mode, cooling can be activated, the fan runs at high speed, and both the first and second air outlets are open. When the indoor unit is operating in anti-direct-blow mode, which generally prevents cold air from blowing directly onto the unit, the first air outlet can be opened and the second air outlet closed. When the indoor unit is operating in defrost mode, which generally prevents cold air from blowing directly onto the unit while heating, the first air outlet can be opened and the second air outlet closed.

[0091] In one specific embodiment, two or more fans can be configured. Preferably, two fans can be configured. The operating state of all the fans mentioned above can be that two fans operate together at corresponding speeds, for example, the fans can operate at a first speed at full power, or two fans can operate at the first speed at full power.

[0092] Furthermore, the cooling and heating modes mentioned above refer to normal cooling and heating modes, where both fans can be controlled to operate at their respective speeds. However, if a silent mode is further set within cooling and heating modes, only one fan can be controlled to operate. Specifically, if a silent mode is set within cooling mode, a single fan can be controlled to operate at a very low speed, with the first air outlet open and the second air outlet closed. Similarly, if a silent mode is set within heating mode, a single fan can be controlled to operate at a very low speed, with the first air outlet closed and the second air outlet open. Additionally, for low-temperature and extremely low-temperature heating situations, such as when the indoor temperature is very low and the detected indoor coil temperature remains consistently low, both fans can be controlled to operate at low speed, with the first air outlet closed and the second air outlet open.

[0093] In summary, the control method for the indoor unit of the wall-mounted air conditioner in this embodiment determines the opening and closing states of the first and second air outlets and the operating state of the fan based on the operating mode, set temperature, and indoor temperature of the indoor unit. This results in a better user experience during both cooling and heating modes, significantly improves the operating efficiency of the indoor unit, effectively reduces noise and energy consumption, and enhances user comfort.

Figure 6 yes Figure 5 A schematic diagram of the overall structure of the indoor unit 100 of a wall-mounted air conditioner from another perspective. Figure 7 This is a top view of the indoor unit 100 of a wall-mounted air conditioner according to an embodiment of the present invention. Figure 8 yes Figure 7 A sectional view of the indoor unit 100 of a wall-mounted air conditioner, cut along line AA. (See image.) Figures 5 to 8 As shown, the indoor unit 100 of the wall-mounted air conditioner may include a housing 110.

[0101] As mentioned earlier, the upper front end of the wall-mounted air conditioner indoor unit 100 is provided with a first air outlet 121, and the lower front end of the wall-mounted air conditioner indoor unit 100 is provided with a second air outlet 122. In practice, the upper front end of the housing 110 may have the first air outlet 121, and the lower front end of the housing 110 may have the second air outlet 122; and the rear side of the housing 110 may have an air inlet 118. In a specific embodiment, the housing 110 may include a front panel 111 and a rear base 112. The upper end of the front panel 111 is provided with the first air outlet 121, and the lower end of the front panel 111 is provided with the second air outlet 122; the rear base 112 is provided with an air inlet 118.

[0102] A first air guide plate 131 is provided at the first air outlet 121 to open and close the first air outlet 121, and a second air guide plate 132 is provided at the second air outlet 122 to open and close the second air outlet. The opening and closing states of the first air outlet 121 and the second air outlet 122 can be adjusted by adjusting the posture of the first air guide plate 131 and the second air guide plate 132. Both the first air guide plate 131 at the first air outlet 121 and the second air guide plate 132 at the second air outlet 122 can be controlled independently, and the opening and closing states of the first air outlet 121 and the second air outlet 122 can be the same or different.

[0103] As mentioned earlier, the indoor unit 100 of the wall-mounted air conditioner is equipped with a fan 113, configured to deliver air to the first air outlet 121 and / or the second air outlet 122. In one specific embodiment, the housing 110 may define a cavity, and the fan 113 may be disposed within the cavity. If two fans 113 are provided, they may be arranged side-by-side in the cavity.

[0104] Furthermore, a heat exchanger 115 can be installed inside the cavity, positioned in front of the fan 113, configured to exchange heat with the air entering the cavity through the air inlet 118. When the indoor unit 100 of the wall-mounted air conditioner is operating in cooling mode, the fan 113 can blow the heat-exchanged cool air towards the first air outlet 121 and / or the second air outlet 122 to lower the indoor temperature; when the indoor unit 100 of the wall-mounted air conditioner is operating in heating mode, the fan 113 can blow the heat-exchanged hot air towards the first air outlet 121 and / or the second air outlet 122 to raise the indoor temperature.

[0105] In a preferred embodiment, the heat exchanger 115 is flat, and the fan 113 consists of two axial flow fans. This combination allows for more uniform heat exchange and air delivery, and is more suitable for dual air outlets, effectively improving heat exchange efficiency and air delivery effect. In a specific embodiment, the fan 113 can be fixed inside the housing 110 by a bracket 116. Furthermore, a filter 117 can be installed behind the fan 113 to filter the air entering the cavity, improving the cleanliness of the air inside the housing 110 and the outlet air. The filter 117 can be mounted on the rear base 112 via a sliding rail, facilitating user disassembly, cleaning, and installation.

[0106] An air guiding mechanism 114 can also be installed inside the cavity, located in front of the heat exchanger 115. This mechanism can adjust the airflow direction according to the opening and closing states of the first air outlet 121 and the second air outlet 122, ensuring smooth airflow. For example, when both the first and second air outlets 121 and 122 are open, the upper part of the air guiding mechanism 114 can guide the air to the first air outlet 121, and the lower part can guide the air to the second air outlet 122. When the first air outlet 121 is open and the second air outlet 122 is closed, the entire air guiding mechanism 114 can completely guide the air to the first air outlet 121. When the first air outlet 121 is closed and the second air outlet 122 is open, the entire air guiding mechanism 114 can completely guide the air to the second air outlet 122. After passing through the air guiding mechanism 114, the airflow exits from the first air outlet 121 and / or the second air outlet 122. The first air guide plate 131 and the second air guide plate 132 can further adjust the airflow direction.

[0107] It should be noted that the control method of the wall-mounted air conditioner indoor unit 100 in this embodiment obtains the operating mode and set temperature of the wall-mounted air conditioner indoor unit 100, detects the indoor temperature of the indoor environment where the wall-mounted air conditioner indoor unit 100 is located, determines the opening and closing state of the first air outlet 121 and the second air outlet 122 according to the operating mode, set temperature and indoor temperature, and controls the first air outlet 121 and the second air outlet 122 to work according to the determined opening and closing state. By adjusting the opening and closing state of the upper and lower air outlets of the wall-mounted air conditioner indoor unit 100, a variety of different air outlet modes can be provided to fully meet the user's usage needs.

[0108] Furthermore, the control method of the wall-mounted air conditioner indoor unit 100 in this embodiment determines the opening and closing states of the first air outlet 121 and the second air outlet 122, and the operating state of the fan 113 based on the operating mode, set temperature, and indoor temperature of the wall-mounted air conditioner indoor unit 100. This results in a better user experience in both cooling and heating modes, greatly improves the operating efficiency of the wall-mounted air conditioner indoor unit 100, effectively reduces noise and energy consumption, and enhances user comfort.
