[0040] like Figures 1 to 6 As shown, this embodiment provides a cooling control method for a wall-mounted air conditioner indoor unit 10. The wall-mounted air conditioner indoor unit 10 includes a lower air guide plate 120, an upper air guide plate 110, a first sway vane assembly 130, and a second sway vane assembly 140. The lower air guide plate 120 is pivotally disposed at the air outlet 11 of the wall-mounted air conditioner indoor unit 10; the upper air guide plate 110 is pivotally disposed above the lower air guide plate 120; the first sway vane assembly 130 and the second sway vane assembly 140 are arranged sequentially along the length direction of the air outlet 11.

[0041] In this embodiment, as Figure 5 As shown, the lower air guide plate 120 is pivotally mounted at the air outlet 11 of the indoor unit 10 of the wall-mounted air conditioner. The lower air guide plate 120 rotates relative to the air outlet 11 to open and close the air outlet 11 and to adjust the size of the air outlet area. In other words, the lower air guide plate 120 is a conventional air guide plate provided with the air outlet 11 of the indoor unit 10 of the wall-mounted air conditioner. Figure 5 As shown, the size of the lower air guide plate 120 is adapted to the size of the air outlet 11, and the lower air guide plate 120 is pivotally disposed on the lower side of the air outlet 11. The pivot axis of the lower air guide plate 120 extends along the length direction of the air outlet 11.

[0042] In this embodiment, as Figure 5 As shown, the pivot axis of the upper air guide plate 110 extends along the length of the air outlet 11, and the upper air guide plate 110 is pivotally disposed above the lower air guide plate 120. The upper air guide plate 110 rotates relative to the lower air guide plate 120 and the air outlet 11 to open and close the air outlet 11 and to adjust the size of the air outlet area of ​​the air outlet 11.

[0043] In this embodiment, the specific number of blades included in the first blade assembly 130 and the second blade assembly 140 is not limited and can be selected as needed. The first blade assembly 130 and the second blade assembly 140 are arranged sequentially along the length of the air outlet 11, that is, the first blade assembly 130 and the second blade assembly 140 are arranged sequentially along the lateral direction of the air outlet 11, that is, the first blade assembly 130 and the second blade assembly 140 are arranged sequentially along the left and right direction of the air outlet 11.

[0044] In this embodiment, the blades of the first oscillating blade assembly 130 and the second oscillating blade assembly 140 are configured to oscillate between a first direction and a second direction along the length of the air outlet 11. The first direction and the second direction are two directions along the length of the air outlet 11. That is, the first direction and the second direction are two directions along the transverse direction of the air outlet 11, that is, the first direction and the second direction respectively point to the left and right directions of the air outlet 11. The oscillation of the blades of the first oscillating blade assembly 130 and the second oscillating blade assembly 140 between the first direction and the second direction along the length of the air outlet 11 allows the first oscillating blade assembly 130 and the second oscillating blade assembly 140 to guide the air from the air outlet 11 to the left and right sides of the wall-mounted air conditioner indoor unit 10, respectively.

[0045] In this embodiment, as Figure 1 As shown, this embodiment provides a cooling control method for the indoor unit 10 of a wall-mounted air conditioner, which includes:

[0046] Step S202: If a cooling command is received from the user, control the lower air guide plate 120 to rotate downwards to the maximum downward blowing position.

[0047] In this embodiment, the method by which the user inputs cooling commands is not limited and can be selected as needed. For example, the user can input via touch on the target interface, and this touch input method can include, but is not limited to, tap input, swipe input, and press input. User input can also be expressed as physical button input. User input can also be expressed as voice input. The target interface can be the display interface of the user terminal or the control interface of the wall-mounted air conditioner.

[0048] In this embodiment, the maximum downward blowing position is also the limit position of the downward rotation of the lower air guide plate 120, that is, the position where the lower air guide plate 120 can no longer rotate downward after rotating to the maximum downward blowing position.

[0049] Step S204: Control the upper air guide plate 110 to rotate upward to the maximum upward blowing position.

[0050] In this embodiment, the maximum upward blowing position is also the limit position of the upper air guide plate 110 rotating upward, that is, the position where the upper air guide plate 110 can no longer rotate upward after rotating to the maximum upward blowing position.

[0051] Step S206: Control the first swashplate assembly 130 to rotate to the first direction along the length of the air outlet 11.

[0052] Step S208: Control the second swashplate assembly 140 to rotate to a second direction facing the length direction of the air outlet 11.

[0053] The first direction and the second direction are two directions along the length of the air outlet 11. That is, the first direction and the second direction are two directions along the lateral side of the air outlet 11, that is, the first direction and the second direction respectively point to the left and right directions of the air outlet 11.

[0054] Therefore, the first sway vane assembly 130 and the second sway vane assembly 140 rotate to the left and right directions of the air outlet 11, respectively. Since the lower air guide plate 120 rotates to its maximum downward blowing position and the upper air guide plate 110 rotates to its maximum upward blowing position, the first sway vane assembly 130 and the second sway vane assembly 140 rotate to the left and right directions of the air outlet 11, respectively. Therefore, the lower air guide plate 120 can guide the air from the air outlet 11 to its lower side, that is, the lower air guide plate 120 can guide the air from the air outlet 11 to the lower side of the wall-mounted air conditioner indoor unit 10. The upper air guide plate 110 can guide the air from the air outlet 11 to its upper side, that is, the upper air guide plate 110 can guide the air from the air outlet 11 to the upper side of the wall-mounted air conditioner indoor unit 10. The first sway vane assembly 130 and the second sway vane assembly 140 can guide the air from the air outlet 11 to the left and right sides of the air outlet 11, respectively. That is, the first sway vane assembly 130 can guide the air from the air outlet 11 to the left and right sides of the wall-mounted air conditioner indoor unit 10, respectively. Therefore, this allows the air blown out by the wall-mounted air conditioner indoor unit 10 to diffuse quickly within the working area of ​​the wall-mounted air conditioner indoor unit 10, so that the temperature in the working area can be reduced to the preset value as quickly as possible. This is called the first stage of the cooling control method of the wall-mounted air conditioner indoor unit 10. Under normal circumstances, in the first stage, the cooling capacity of the wall-mounted air conditioner indoor unit 10 is turned on to the maximum. With the cooling control method of the first stage, the temperature in the working area can be rapidly reduced to the preset value.

[0055] In some other embodiments, the step of controlling the second vane assembly 140 to rotate to a second direction toward the length direction of the air outlet 11 further includes:

[0056] The temperature of the working area of ​​the indoor unit 10 of the wall-mounted air conditioner is obtained at preset time intervals;

[0057] If the temperature of the working area is lower than the preset value, control the first swing blade assembly 130 and the second swing blade assembly 140 to swing between the first direction and the second direction.

[0058] Control both the upper air guide plate 110 and the lower air guide plate 120 to rotate to the maximum upward blowing position.

[0059] In this embodiment, the specific value of the preset time interval is not limited and can be selected as needed. For example, the range of the preset time interval can be from 0.5 minutes to 5 minutes. Specifically, the preset time interval can be 1 minute, 2 minutes, 3 minutes, or 4 minutes, etc.

[0060] In this embodiment, the specific method for obtaining the temperature of the working area of ​​the wall-mounted air conditioner indoor unit 10 is not limited and can be selected as needed. For example, a first temperature sensor is provided on the body of the wall-mounted air conditioner indoor unit 10, and the temperature value detected by the first temperature sensor is the temperature of the working area. Alternatively, the wall-mounted air conditioner indoor unit 10 may have a first temperature sensor on its body, and at least one second temperature sensor may be respectively located at other positions in the working area. The wall-mounted air conditioner indoor unit 10 may also have a receiving module corresponding to each of the at least one second temperature sensor to receive the temperature detected by each sensor. The temperature of the working area is the average of the temperature detected by the first temperature sensor and the temperature detected by the at least one second temperature sensor.

[0061] In some other embodiments, at least one second temperature sensor is uniformly arranged within the working area, which facilitates accurate acquisition of the temperature within the working area.

[0062] In this embodiment, the specific value of the preset value is not limited and can be selected as needed. For example, the range of the preset value can be 24℃ to 28℃. Specifically, the preset value can be 25℃, 26℃, or 27℃, etc. If the temperature of the working area is lower than the preset value, it means that the temperature of the working area has reached the user-set comfortable temperature.

[0063] If the temperature in the working area is lower than the preset value, the first swing blade assembly 130 and the second swing blade assembly 140 are controlled to swing between the first direction and the second direction, that is, the first swing blade assembly 130 and the second swing blade assembly 140 are controlled to swing left and right. This allows the indoor unit 10 of the wall-mounted air conditioner to deliver a gentle breeze to the working area, so as to avoid direct cold air blowing and improve people's comfort.

[0064] If the temperature in the working area is lower than the preset value, both the upper air guide plate 110 and the lower air guide plate 120 are rotated to the maximum upward blowing position. This allows the indoor unit 10 of the wall-mounted air conditioner to blow cold air upwards, avoiding cold air blowing downwards and causing discomfort to the user. This is called the second stage of the cooling control method of the indoor unit 10 of the wall-mounted air conditioner. Generally, the cooling capacity of the indoor unit 10 of the wall-mounted air conditioner in the second stage is lower than that in the first stage. With the cooperation of this second stage cooling control method, the indoor temperature can be lowered gently to improve people's comfort.

[0065] In some other embodiments, the upper air guide plate 110 includes a first sub-upper air guide plate 111 and a second sub-upper air guide plate 112 arranged sequentially along the length of the air outlet 11. The wall-mounted air conditioner indoor unit 10 also includes a first fan 150 and a first heat exchange system 170 arranged corresponding to the first sub-upper air guide plate 111. The wall-mounted air conditioner indoor unit 10 also includes a second fan 160 and a second heat exchange system 180 arranged corresponding to the second sub-upper air guide plate 112. The wall-mounted air conditioner indoor unit 10 also includes a human body detection device.

[0066] After the step of controlling both the upper air guide plate 110 and the lower air guide plate 120 to rotate to the maximum upward blowing position, the following is also included:

[0067] If both the upper air guide plate 110 and the lower air guide plate 120 rotate to the maximum upward blowing position for a preset time, the location of the human body is determined based on the detection data of the human body detection device.

[0068] If a human body is located in the radiation area of ​​the first upper air guide plate 111, the first upper air guide plate 111, the first fan 150 and the first heat exchange system 170 are all shut down.

[0069] In this embodiment, the upper air guide plate 110 includes a first sub-upper air guide plate 111 and a second sub-upper air guide plate 112 arranged sequentially along the length of the air outlet 11. That is, the upper air guide plate 110 includes a first sub-upper air guide plate 111 and a second sub-upper air guide plate 112 arranged sequentially along the transverse direction of the air outlet 11, and also includes a first sub-upper air guide plate 111 and a second sub-upper air guide plate 112 arranged sequentially along the left and right directions of the air outlet 11. Specifically, the first sub-upper air guide plate 111 and the second sub-upper air guide plate 112 are located on the left and right sides of the air outlet 11, respectively. Figure 5 As shown, the first upper air guide plate 111 is located on the left side of the air outlet 11, and the second upper air guide plate 112 is located on the right side of the air outlet 11.

[0070] In this embodiment, the indoor unit 10 of the wall-mounted air conditioner also includes a first fan 150 and a first heat exchange system 170, which are correspondingly arranged with the first upper air guide plate 111. That is, the outlet of the first fan 150 corresponds to the first upper air guide plate 111, and the air blown by the first fan 150 flows out from the first upper air guide plate 111. Specifically, the first heat exchange system 170 includes a first indoor heat exchanger, that is, the air blown by the first fan 150 flows through the first indoor heat exchanger.

[0071] The first indoor heat exchanger and the first fan 150 are respectively arranged corresponding to the first upper air guide plate 111, that is, the first indoor heat exchanger and the first fan 150 are both arranged on one side of the first upper air guide plate 111. Figure 5 As shown, the first upper air guide plate 111 is located on the left side of the air outlet 11, and the first indoor heat exchanger and the first fan 150 are also located on the left side of the air outlet 11, that is, on the left side of the indoor unit 10 of the wall-mounted air conditioner.

[0072] In this embodiment, the indoor unit 10 of the wall-mounted air conditioner also includes a second fan 160 and a second heat exchange system 180, which are correspondingly arranged with respect to the second upper air guide plate 112. That is, the outlet of the second fan 160 corresponds to the second upper air guide plate 112, and the air blown by the second fan 160 flows out from the second upper air guide plate 112. Specifically, the second heat exchange system 180 includes a second indoor heat exchanger, that is, the air blown by the second fan 160 flows through the indoor heat exchanger.

[0073] The second indoor heat exchanger and the second fan 160 are respectively arranged corresponding to the second upper air guide plate 112, that is, the second indoor heat exchanger and the second fan 160 are both located on one side of the second upper air guide plate 112. Figure 5 As shown, the second upper air guide plate 112 is located on the right side of the air outlet 11, and the second indoor heat exchanger and the second fan 160 are also located on the right side of the air outlet 11, that is, on the right side of the indoor unit 10 of the wall-mounted air conditioner.

[0074] In this embodiment, the specific range of the preset time is not limited and can be selected as needed. For example, the specific range of the preset time can be 15 minutes to 30 minutes. Specifically, the preset time can be 15 minutes, 20 minutes, 25 minutes, or 30 minutes.

[0075] In this embodiment, the specific type of human detection device is not limited. For example, the human detection device can be a camera, which can be a regular camera or an infrared camera. Calculating the position of a human body based on photos taken by a camera or infrared camera is existing technology and will not be elaborated upon here.

[0076] In this embodiment, if a human body is located within the radiation area of ​​the first upper air guide plate 111, the first upper air guide plate 111, the first fan 150, and the first heat exchange system 170 are all turned off. The second upper air guide plate 112, the second fan 160, and the second heat exchange system 180 are turned on. This ensures that the temperature of the working area remains at a suitable level while preventing cold air from blowing towards the user, thus improving the user's comfort.

[0077] In some other embodiments, the step of determining the location of a human body based on data detected by the human body detection device further includes:

[0078] If a human body is located in the radiation area of ​​the second upper air guide plate 112, the second upper air guide plate 112, the second fan 160, and the second heat exchange system 180 are all shut down.

[0079] In this embodiment, if a human body is located within the radiation area of ​​the second upper air guide plate 112, the second upper air guide plate 112, the second fan 160, and the second heat exchange system 180 are all turned off. The first upper air guide plate 111, the first fan 150, and the first heat exchange system 170 are turned on. This ensures that the temperature of the working area remains at a suitable level and prevents cold air from blowing towards the user, thus improving the user's comfort.

[0080] This is called the third stage of the cooling control method of the indoor unit 10 of the wall-mounted air conditioner. Generally, the cooling capacity of the indoor unit 10 of the wall-mounted air conditioner in the third stage is lower than that in the second stage. With the cooling control method of the third stage, this can ensure that the temperature of the working area is always at a suitable temperature, and also prevent cold air from blowing towards the user, thereby improving the user's comfort.

[0081] In some other embodiments, the cooling intensity of the indoor unit 10 of the wall-mounted air conditioner is configured to decrease sequentially from a temperature in the working area that is greater than a preset value to a temperature in the working area that is lower than a preset value, until the upper air guide plate 110 and the lower air guide plate 120 are both rotated to the maximum downward blowing position for a preset time.

[0082] In other words, the cooling capacity of the wall-mounted air conditioner indoor unit 10 is configured to decrease sequentially from the first stage to the second stage, and then to the third stage. Specifically, the cooling capacity of the first stage of the wall-mounted air conditioner indoor unit 10 is greater than that of the second stage, and also greater than that of the third stage. This ensures that the temperature in the working area of ​​the wall-mounted air conditioner indoor unit 10 quickly drops below the preset value in the first stage, gently lowers the temperature to a comfortable level in the second stage, and maintains a consistently suitable temperature in the third stage while avoiding direct cold airflow, thus improving user comfort.

[0083] In some other embodiments, the rotational speeds of the first fan 150 and the second fan 160 are configured to decrease sequentially from when the temperature of the working area is greater than a preset value to when the temperature of the working area is lower than a preset value, until the upper air guide plate 110 and the lower air guide plate 120 both rotate to the maximum downward blowing position for a preset time.

[0084] In other words, the rotational speeds of both the first fan 150 and the second fan 160 are configured to decrease sequentially from the first stage to the second stage, and then to the third stage. Specifically, the rotational speeds of the first fan 150 and the second fan 160 in the first stage are greater than their rotational speeds in the second stage, and also greater than their rotational speeds in the third stage. This ensures that the temperature in the working area of ​​the indoor unit 10 of the wall-mounted air conditioner quickly drops below the preset value in the first stage, gently lowers the temperature to a comfortable level in the second stage, and maintains a consistently suitable temperature in the third stage while avoiding direct cold airflow, thus improving user comfort.

[0085] In some other implementations, the preset time ranges from 15 minutes to 25 minutes.

[0086] In some other implementations, the temperature of the working area is the average temperature of the working area.

[0087] In this embodiment, a first temperature sensor is installed on the body of the wall-mounted air conditioner indoor unit 10, and at least one second temperature sensor is respectively installed at other locations in the working area. The body of the wall-mounted air conditioner indoor unit 10 is equipped with a receiving module corresponding to each of the at least one second temperature sensor to receive the temperature detected by each sensor. The temperature of the working area is the average of the temperature detected by the first temperature sensor and the temperature detected by the at least one second temperature sensor; that is, the temperature of the working area is the average temperature of the working area.

[0088] like Figure 2 As shown, another embodiment of the present invention also provides a cooling control method for an indoor unit 10 of a wall-mounted air conditioner, comprising:

[0089] Step S302: If a cooling command is received from the user, control the lower air guide plate 120 to rotate downwards to the maximum downward blowing position.

[0090] Step S304: Control the upper air guide plate 110 to rotate upward to the maximum upward blowing position.
