[0040] like Figures 1 to 6 As shown, this embodiment provides a refrigeration control method for a wall-mounted air conditioner indoor unit 10, wherein the wall-mounted air conditioner indoor unit 10 includes a lower air guide plate 120, an upper air guide plate 110, a first swing blade assembly 130 and a second swing blade 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 on the upper side of the lower air guide plate 120; the first swing blade assembly 130 and the second swing blade assembly 140 are sequentially disposed along the length direction of the air outlet 11.

[0041] In this embodiment, if Figure 5 As shown, the lower air guide plate 120 is pivotally disposed at the air outlet 11 of the wall-mounted air conditioner indoor unit 10, and 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 of ​​the air outlet 11. In other words, the lower air guide plate 120 is a traditional air guide plate provided at the air outlet 11 of the wall-mounted air conditioner indoor unit 10. Figure 5 As shown, the size of the lower air guide plate 120 matches the size of the air outlet 11, and the lower air guide plate 120 is pivotally disposed at 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, if Figure 5 As shown, the pivot axis of the upper air guide plate 110 extends along the length direction of the air outlet 11, and the upper air guide plate 110 is pivotally arranged on the upper side of 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 the swing blades included in the first swing blade assembly 130 and the second swing blade assembly 140 is not limited and can be selected as needed. The first swing blade assembly 130 and the second swing blade assembly 140 are sequentially arranged along the length direction of the air outlet 11, that is, the first swing blade assembly 130 and the second swing blade assembly 140 are sequentially arranged along the transverse direction of the air outlet 11, that is, the first swing blade assembly 130 and the second swing blade assembly 140 are sequentially arranged along the left and right direction of the air outlet 11.

[0044] In the present embodiment, the blades of the first swing blade assembly 130 and the blades of the second swing blade assembly 140 are configured to swing between a first direction and a second direction along the length direction of the air outlet 11. The first direction and the second direction are two directions along the length direction of the air outlet 11. That is, the first direction and the second direction are two directions along the lateral direction of the air outlet 11, that is, the first direction and the second direction respectively indicate the left and right directions of the air outlet 11. The blades of the first swing blade assembly 130 and the blades of the second swing blade assembly 140 are configured to swing between a first direction and a second direction along the length direction of the air outlet 11, which enables the first swing blade assembly 130 and the second swing blade assembly 140 to respectively guide the wind of the air outlet 11 to the left and right sides of the indoor unit 10 of the wall-mounted air conditioner.

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

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

[0047] In this embodiment, the user inputs the cooling command in any manner, which can be selected as needed. For example, the user can input by touch on the target interface, and the touch input method can include but is not limited to click input, slide input, and press input. The user input can also be expressed as physical button input. The user input can also be expressed as voice input. Among them, the target interface can be a display interface of the user terminal, and can also be a control interface of the wall-mounted air conditioner.

[0048] In the present 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 cannot rotate downward any further after rotating downward to the maximum downward blowing position.

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

[0050] In the present embodiment, the maximum upward blowing position is also the limit position of the upward rotation of the upper air guide plate 110 , that is, the position where the upper air guide plate 110 cannot rotate upward any further after rotating upward to the maximum upward blowing position.

[0051] Step S206 : controlling the first swing blade assembly 130 to rotate to a first direction in the length direction of the air outlet 11 .

[0052] Step S208 : controlling the second swing blade assembly 140 to rotate to a second direction in the length direction of the air outlet 11 .

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

[0054] Therefore, the first swing blade assembly 130 and the second swing blade assembly 140 are respectively rotated to the left and right directions of the air outlet 11. Since the lower air guide plate 120 rotates to the maximum downward blowing position and the upper air guide plate 110 rotates to the maximum upward blowing position, the first swing blade assembly 130 and the second swing blade assembly 140 are respectively rotated to the left and right directions of the air outlet 11. Therefore, the lower air guide plate 120 can guide the wind from the air outlet 11 to the lower side of the air outlet 11, that is, the lower air guide plate 120 can guide the wind 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 wind from the air outlet 11 to the upper side of the air outlet 11, that is, the upper air guide plate 110 can guide the wind from the air outlet 11 to the upper side of the wall-mounted air conditioner indoor unit 10. The first swing blade assembly 130 and the second swing blade assembly 140 can guide the wind from the air outlet 11 to the left and right sides of the air outlet 11, that is, the first swing blade assembly 130 can guide the wind 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 wind blown out of the wall-mounted air conditioner indoor unit 10 to diffuse in the working area of ​​the wall-mounted air conditioner indoor unit 10 as quickly as possible, so that the temperature in the working area can be reduced to a preset value as quickly as possible. This is called the first stage of the refrigeration control method of the wall-mounted air conditioner indoor unit 10. Generally, in the first stage, the refrigeration capacity of the wall-mounted air conditioner indoor unit 10 is opened to the maximum. In conjunction with the refrigeration control method of the first stage, the temperature of the working area can be quickly reduced to a preset value.

[0055] In some other embodiments, after the step of controlling the second swing blade assembly 140 to rotate to the second direction in the length direction of the air outlet 11, the method further includes:

[0056] Obtaining the temperature of the working area of ​​the indoor unit 10 of the wall-mounted air conditioner at a preset time interval;

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

[0058] The upper air guide plate 110 and the lower air guide plate 120 are controlled 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 value range of the preset time interval can be 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 of 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. For example, a first temperature sensor is provided on the body of the wall-mounted air conditioner indoor unit 10, and at least one second temperature sensor is respectively provided at other positions of the working area, and a receiving module corresponding to at least one second temperature sensor is respectively provided on the body of the wall-mounted air conditioner indoor unit 10 to respectively receive the temperature detected by at least one second temperature sensor. The temperature of the working area is the average value of the temperature detected by the first temperature sensor and the temperature detected by at least one second temperature sensor.

[0061] In some other embodiments, at least one second temperature sensor is evenly disposed in the working area, which facilitates accurate acquisition of the temperature in 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 preset value range may be 24°C to 28°C. Specifically, the preset value may be 25°C, 26°C or 27°C. If the temperature of the working area is lower than the preset value, it means that the temperature of the working area has reached a relatively comfortable temperature set by the user.

[0063] If the temperature of the working area is lower than a 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 wall-mounted air conditioner indoor unit 10 to deliver soft wind to the working area to avoid direct cold wind and improve people's comfort.

[0064] If the temperature of the working area is lower than the preset value, the upper air guide plate 110 and the lower air guide plate 120 are controlled to rotate to the maximum upward blowing position. This enables the wall-mounted air conditioner indoor unit 10 to blow the cold air upward, avoiding the cold air blowing downward, which causes discomfort to the user. This is called the second stage of the refrigeration control method of the wall-mounted air conditioner indoor unit 10. Generally, the refrigeration capacity of the wall-mounted air conditioner indoor unit 10 in the second stage is lower than the refrigeration capacity of the first stage. With the refrigeration control method of the second stage, the indoor temperature can be gently reduced 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 sequentially arranged 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, and the wall-mounted air conditioner indoor unit 10 also includes a human body detection device;

[0066] After the step of controlling the upper air guide plate 110 and the lower air guide plate 120 to rotate to the maximum upward blowing position, the method further includes:

[0067] If the upper air guide plate 110 and the lower air guide plate 120 are both rotated to the maximum upward blowing position for a preset time, the position of the human body is determined according to the detection data of the human body detection device;

[0068] If the human body is located in the radiation area of ​​the first upper sub-air guide plate 111, the first upper sub-air guide plate 111, the first fan 150 and the first heat exchange system 170 are all controlled to be closed.

[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 sequentially arranged 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 sequentially arranged along the lateral direction 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 sequentially arranged along the left and right directions of the air outlet 11. That is, the first sub-upper air guide plate 111 and the second sub-upper air guide plate 112 are respectively located on the left and right sides of the air outlet 11, specifically, as shown in FIG. Figure 5 As shown, the first upper sub-air guide plate 111 is located on the left side of the air outlet 11 , and the second upper sub-air guide plate 112 is located on the right side of the air outlet 11 .

[0070] In this embodiment, the wall-mounted air conditioner indoor unit 10 further includes a first fan 150 and a first heat exchange system 170 which are arranged corresponding to the first upper sub-air guide plate 111, that is, the outlet of the first fan 150 corresponds to the first upper sub-air guide plate 111, that is, the wind blown by the first fan 150 flows out from the first upper sub-air guide plate 111. Specifically, the first heat exchange system 170 includes a first indoor heat exchanger, that is, the wind 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 sub-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 sub-air guide plate 111. Figure 5 As shown, the first upper sub-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 wall-mounted air conditioner indoor unit 10 further includes a second fan 160 and a second heat exchange system 180 arranged corresponding to the second upper sub-air guide plate 112, that is, the outlet of the second fan 160 corresponds to the second upper sub-air guide plate 112, that is, the wind blown by the second fan 160 flows out from the second upper sub-air guide plate 112. Specifically, the second heat exchange system 180 includes a second indoor heat exchanger, that is, the wind 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 sub-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 sub-air guide plate 112. Figure 5 As shown, the second upper sub-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 numerical 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 the human body detection device is not limited. For example, the human body detection device can be a camera, and the camera can be an ordinary camera or an infrared camera. Calculating the position of the human body based on the photos taken by the camera or infrared camera is a prior art and will not be described in detail here.

[0076] In this embodiment, if the human body is located in the radiation area of ​​the first upper sub-air guide plate 111, the first upper air guide plate 111, the first fan 150 and the first heat exchange system 170 are all controlled to be closed. The second upper sub-air guide plate 112, the second fan 160 and the second heat exchange system 180 are controlled to be opened, which can ensure that the temperature of the working area is always at a suitable temperature and prevent cold wind from blowing towards the user, thereby improving the user's comfort.

[0077] In some other implementations, after the step of determining the location of the human body according to the detection data of the human body detection device, the method further includes:

[0078] If the human body is located in the radiation area of ​​the second upper sub-air guide plate 112, the second upper sub-air guide plate 112, the second fan 160 and the second heat exchange system 180 are all controlled to be closed.

[0079] In this embodiment, if the human body is located in the radiation area of ​​the second upper sub-air guide plate 112, the second upper air guide plate 112, the second fan 160 and the second heat exchange system 180 are all controlled to be closed. The first upper sub-air guide plate 111, the first fan 150 and the first heat exchange system 170 are controlled to be opened, which can ensure that the temperature of the working area is always at a suitable temperature and prevent cold wind from blowing towards the user, thereby improving the user's comfort.

[0080] This is called the third stage of the refrigeration control method of the wall-mounted air conditioner indoor unit 10. Generally, the refrigeration capacity of the wall-mounted air conditioner indoor unit 10 in the third stage is lower than the refrigeration capacity of the wall-mounted air conditioner indoor unit 10 in the second stage. Combined with the refrigeration control method of the third stage, this can not only ensure that the temperature of the working area is always at a suitable temperature, but also avoid cold wind blowing towards the user, thereby improving the user's comfort.

[0081] In some other embodiments, the cooling intensity of the wall-mounted air conditioner indoor unit 10 is configured to decrease successively from the temperature of the working area being greater than a preset value to the temperature of the working area being 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 after a preset time.

[0082] In other words, the refrigeration intensity of the wall-mounted air conditioner indoor unit 10 is configured to decrease from the first stage to the second stage to the third stage. That is, the refrigeration intensity of the wall-mounted air conditioner indoor unit 10 in the first stage is greater than the refrigeration intensity of the wall-mounted air conditioner indoor unit 10 in the second stage, and greater than the refrigeration intensity of the wall-mounted air conditioner indoor unit 10 in the third stage. This allows the temperature of the working area of ​​the wall-mounted air conditioner indoor unit 10 to be lower than the preset value as soon as possible in the first stage, the temperature of the working area can be gently reduced to a comfortable temperature in the second stage, and the third stage can ensure that the temperature of the working area is always at a suitable temperature, and avoid direct cold wind, thereby 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 successively from a temperature of the working area being greater than a preset value to a temperature of the working area being lower than a preset value, and after 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.

[0084] In other words, the rotation speeds of the first fan 150 and the second fan 160 are configured to decrease from the first stage to the second stage and to the third stage. That is, the rotation speeds of the first fan 150 and the second fan 160 in the first stage are greater than the rotation speeds of the first fan 150 and the second fan 160 in the second stage, and greater than the rotation speeds of the first fan 150 and the second fan 160 in the third stage. This allows the temperature of the working area of ​​the wall-mounted air conditioner indoor unit 10 to be lower than the preset value as soon as possible in the first stage, the temperature of the working area can be gently reduced to a comfortable temperature in the second stage, and the temperature of the working area can be ensured to be at a suitable temperature at all times in the third stage, while avoiding direct cold wind, thereby improving user comfort.
