[0040] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0041] This disclosure provides an air conditioner, which includes a casing 100 and an indoor heat exchanger 110. For example... Figure 1 As shown, the casing 100 has an air outlet 101 and an air inlet 102, and the indoor heat exchanger 110 is disposed inside the casing 100. When the air conditioner is running in dehumidification mode, the indoor heat exchanger 110 cools the air. Air enters the casing 100 through the air inlet 102 and encounters condensation water as it passes through the indoor heat exchanger 110, thus reducing the humidity of the air. Then, the low-temperature, dry air is blown into the room through the air outlet 101, but this also results in a lower indoor temperature.

[0042] In some embodiments, the air conditioner further includes a heating device 200. The heating device 200 includes a first heating section 210 and a second heating section 220. The first heating section 210 is rotatably disposed on a first side of the air outlet 101, and the second heating section 220 is rotatably disposed on a second side of the air outlet 101. Furthermore, the heating device 200 has a heating position and a retraction position. The heating position corresponds to the airflow path where the first heating section 210 and / or the second heating section 220 rotates to the air outlet 101, and the retraction position corresponds to the first heating section 210 and the second heating section 220 retracting from the airflow path.

[0043] In this embodiment, the heating device 200 is located at the air outlet 101. When the first heating part 210 and / or the second heating part 220 rotate to the heating position, the air blown out from the air outlet 101 can be heated. Thus, when the air conditioner is cooling and dehumidifying, the temperature of the low-temperature, dry air increases as it flows through the heating device 200, thereby increasing the air outlet temperature of the air conditioner and achieving a constant temperature dehumidification effect. Furthermore, when the air conditioner does not require constant temperature dehumidification, the first heating part 210 and the second heating part 220 can rotate to a clearance position, at which time the heating device 200 does not affect the normal air outlet of the air conditioner.

[0044] Optionally, such as Figure 2 As shown, the first heating unit 210 includes a mounting plate 240 and a heating element 250. A rotating shaft 244 is provided on the first side of the mounting plate 240. The heating element 250 is disposed on the mounting plate 240 and is used to heat the flowing air. Furthermore, the second heating unit 220 has the same structure as the first heating unit 210.

[0045] In this embodiment, to facilitate the distinction between the first heating part 210 and the second heating part 220, the mounting plates 240 of the first heating part 210 and the second heating part 220 are respectively referred to as the first mounting plate 241 and the second mounting plate 242, and the heating elements 250 are respectively referred to as the first heating element 251 and the second heating element 252. The second side of each mounting plate 240 can be rotated around the corresponding pivot 244.

[0046] Optionally, the length direction of the mounting plate 240 is parallel to the length direction of the air outlet 101. Furthermore, the first mounting plate 241 is located on a first side of the width direction of the air outlet 101, for example, on the upper side of the air outlet 101. The second mounting plate 242 is located on a second side of the width direction of the air outlet 101, for example, on the lower side of the air outlet 101.

[0047] Optionally, such as Figure 2As shown, the heating element 250 includes a heating band 253 and a heat sink 254. The heating band 253 is connected to a heating power source, and generates heat when the power source is energized. The heat sink 254 is disposed on the heating band 253 to dissipate heat. Thus, when the heating power source is energized, the heating band 253 generates heat. Furthermore, the heat sink 254 efficiently dissipates heat to the flowing air.

[0048] Optionally, the heating band 253 is arranged along the length of the mounting plate 240, and multiple heat sinks 254 are symmetrically arranged on both sides of the heating band 253. In this way, a longer heating band 253 can be arranged, and the temperature diffusion of the heat sinks 254 is more uniform, thereby improving the heating effect of the heating element 250.

[0049] Optionally, such as Figure 2 As shown, the mounting plate 240 is provided with ventilation holes 243.

[0050] In this embodiment, when the heating device 200 is in the heating position, it obstructs the airflow because it is located in the airflow path of the air outlet 101. Here, by providing ventilation holes 243 on the mounting plate 240, the obstruction can be reduced, thereby improving the airflow effect. Furthermore, when the heating device 200 is in the clearance position, when the heating element 250 is activated, heat can be diffused to the flowing air through the ventilation holes 243.

[0051] Optionally, the diameter of the ventilation hole 243 is d, and 1mm≤d≤2mm. In this way, by setting a reasonable hole diameter, it is beneficial to make the air outlet smoother.

[0052] In some embodiments, such as Figure 4 As shown, the air conditioner also includes a cross-flow duct 300. The cross-flow duct 300 includes an upper duct wall 310 and a lower duct wall 320, and the ends of the upper duct wall 310 and the lower duct wall 320 enclose a duct outlet, which faces the air outlet 101. A first compartment 311 is provided outside the end of the upper duct wall 310, which houses the first heating element 210. A second compartment 321 is provided outside the end of the lower duct wall 320, which houses the second heating element 220.

[0053] In this embodiment, the first end of the upper wall 310 and the first end of the lower wall 320 of the air duct enclose and form the air duct inlet. A cross-flow fan 120 is installed inside the cross-flow air duct 300. When the cross-flow fan 120 is started, air enters the cross-flow air duct 300 from the air duct inlet, then is blown from the air duct outlet to the air outlet 101, and finally blown into the room from the air outlet 101. By providing the first chamber 311 and the second chamber 321, the internal space of the cross-flow air duct 300 is not occupied, and space is provided for the first heating unit 210 and the second heating unit 220.

[0054] Optionally, such as Figure 5 As shown, a front volute tongue 312 is provided at the end of the upper wall 310 of the air duct. In the avoidance position, the heating element 250 of the first heating part 210 is located in the first compartment 311, the mounting plate 240 of the first heating part 210 covers the first compartment 311, and the second side of the mounting plate 240 corresponds to the front volute tongue 312.

[0055] In this embodiment, at the avoidance position, the first mounting plate 241 covers the first compartment 311, preventing debris from entering the first compartment 311. When the second side of the first mounting plate 241 corresponds to the front volute 312, air flows out from the front volute 312 and continues to flow along the first mounting plate 241 towards the air outlet 101. Thus, the first mounting plate 241 also serves to guide airflow. Figure 5 As shown, when the first mounting plate 241 is provided with ventilation holes 243, even if the first mounting plate 241 is in a clearance position, as long as the first heating element 251 starts heating, heat can be transferred to the flowing air through the ventilation holes 243. In this way, the outlet air temperature can be increased without obstructing the outlet air.

[0056] Optionally, such as Figure 7 As shown, the mounting plate 240 of the first heating unit 210 can be rotated from the clearance position toward the air outlet 101 to the heating position. The rotation angle of the mounting plate 240 is α, and 0°≤α≤53°.

[0057] In this embodiment, the first mounting plate 241 is positioned to cover the first compartment 311 and corresponds to the front volute 312, with a rotation angle α of 0°. Figure 5 As shown. The first mounting plate 241 is rotated to its limit position toward the air outlet 101, with a rotation angle α of 53°, as shown. Figure 7 As shown.

[0058] Optionally, the first heating unit 210 further includes a first motor, which drives the first mounting plate 241 to rotate. The first motor is electrically connected to a heating controller, which adjusts the rotation angle α of the first mounting plate 241 via the first motor.

[0059] Optionally, such as Figure 6 As shown, an air outlet section 323 is provided at the end of the lower wall 320 of the air duct. In the avoidance position, the heating element 250 of the second heating part 220 is located in the second compartment 321, the mounting plate 240 of the second heating part 220 covers the second compartment 321, and the second side of the mounting plate 240 corresponds to the air outlet section 323.

[0060] In this embodiment, at the avoidance position, the second mounting plate 242 covers the second compartment 321, preventing debris from entering the second compartment 321. When the second side of the second mounting plate 242 corresponds to the air outlet section 323, after air flows out of the air outlet section 323, it continues to flow along the second mounting plate 242 towards the air outlet 101. Thus, the second mounting plate 242 also serves to guide airflow. Figure 6 As shown, when the second mounting plate 242 is provided with ventilation holes 243, even if the second mounting plate 242 is in a clearance position, as long as the second heating element 252 starts heating, heat can be transferred to the flowing air through the ventilation holes 243. In this way, the outlet air temperature can be increased without obstructing the outlet air.

[0061] Optionally, such as Figure 7 As shown, the mounting plate 240 of the second heating unit 220 can be rotated from the clearance position toward the air outlet 101 to the heating position. The rotation angle of the mounting plate 240 is β, and 0°≤β≤65°.

[0062] In this embodiment, the second mounting plate 242 is positioned at a location that covers the second compartment 321 and corresponds to the air outlet section 323, with a rotation angle β of 0°. Figure 6 As shown. The second mounting plate 242 is rotated to its limit position toward the air outlet 101, with a rotation angle β of 65°, as shown. Figure 7 As shown.

[0063] Optionally, the second heating unit 220 further includes a second motor for driving the second mounting plate 242 to rotate. The second motor is electrically connected to a heating controller, which adjusts the rotation angle β of the second mounting plate 242 via the second motor.

[0064] Optionally, even after the first mounting plate 241 and the second mounting plate 242 are rotated to their respective extreme positions, a flow gap still exists between them. Different rotation angles of the mounting plate 240 result in different heating effects on the flowing air. Specifically, when α is 53° and β is 65°, the flowing air can fully contact the first heating element 251 and the second heating element 252, resulting in the best heating effect at this angle. Furthermore, the flow gap ensures the airflow volume of the air conditioner.

[0065] In some embodiments, such as Figure 1As shown, the air conditioner also includes an air guide plate 260. The air guide plate 260 is rotatably mounted at the air outlet 101. The heating device 200 also includes a third heating unit 230, which is mounted on the air guide plate 260. In this way, the air guide plate 260 can guide the direction of the airflow, and the third heating unit 230 can heat the air flowing through it. The combined use of the first heating unit 210, the second heating unit 220, and the third heating unit 230 further improves the effect of constant temperature and dehumidification.

[0066] Optionally, such as Figure 3 As shown, the third heating element 230 is embedded within the air guide plate 260. The third heating element 230 includes an embedded heating strip 261 and an embedded heat sink 262. The embedded heating strip 261 is connected to a heating power source, and generates heat when the heating power source is energized. The embedded heat sink 262 is disposed on the embedded heating strip 261 for dissipating heat.

[0067] In this embodiment, since the air guide plate 260 mainly serves to guide the airflow direction, the third heating unit 230 is installed in an embedded manner to ensure the airflow guiding effect. Thus, when the heating power supply is turned on, the embedded heating element 261 generates heat. Furthermore, under the action of the embedded heat sink 262, the heat is diffused to the plate body of the air guide plate 260, thereby heating the air flowing through the air guide plate 260.

[0068] Optionally, the embedded heating strip 261 is arranged along the length of the air guide plate 260, and the embedded heat sink 262 is arranged along the width of the air guide plate 260.

[0069] Optionally, the third heating unit 230 also includes a third motor, which drives the air guide plate 260 to rotate. The third motor is electrically connected to the heating controller, which adjusts the rotation angle of the air guide plate 260 via the third motor.

[0070] This disclosure also provides a method for controlling an air conditioner, the structure of which is detailed above. Figure 9 As shown, the method includes:

[0071] S10: The heating controller obtains the temperature difference between the set temperature and the indoor temperature, and obtains the indoor relative humidity;

[0072] S20: The heating controller controls the operating status of the first heating section and the second heating section based on the temperature difference and relative humidity.

[0073] In this embodiment, when the air conditioner is cooling and dehumidifying, the indoor temperature is usually lower than the user's set temperature, causing discomfort to the user. This embodiment includes a heating device at the air outlet, and both the first and second heating units can heat the air blown out from the outlet. Thus, the temperature of the dehumidified, low-temperature, dry air increases as it flows through the heating device, thereby raising the indoor temperature. Therefore, by controlling the operation of the first and second heating units based on the temperature difference and relative humidity, a constant-temperature dehumidification effect can be achieved. Here, the indoor temperature is denoted as t0, the set temperature as t1, and the temperature difference between the set temperature and the indoor temperature as T, then t1 - t0 = T.

[0074] Optionally, in step S20, the heating controller controls the operating status of the first heating unit and the second heating unit based on the temperature difference and relative humidity, including:

[0075] The heating controller controls the rotation angle of the first and second mounting plates, as well as the opening and closing of the first and second heating elements, based on the temperature difference and relative humidity.

[0076] In this embodiment, when the first heating element and the second heating element are turned on, the flowing air can be heated. When the first heating element and the second heating element are turned off, the air cannot be heated. Furthermore, the different rotation angles of the first mounting plate and the second mounting plate result in different heating effects on the flowing air.

[0077] Optionally, such as Figure 10 As shown, the steps include: the heating controller controls the rotation angle of the first and second mounting plates and controls the opening or closing of the first and second heating elements based on the temperature difference and relative humidity, including:

[0078] S21: When the relative humidity is greater than or equal to the first humidity threshold and the temperature difference is greater than zero and less than the first temperature threshold, the heating controller controls the first mounting plate and the second mounting plate not to rotate, and the heating controller controls the first heating element and the second heating element to start.

[0079] S22: When the relative humidity is greater than or equal to the first humidity threshold and the temperature difference is greater than or equal to the first temperature threshold, the heating controller controls the first mounting plate and the second mounting plate to rotate from the first compartment and the second compartment toward the air outlet, respectively, and the heating controller controls the first heating element and the second heating element to start.

[0080] S23: When the relative humidity is less than the second humidity threshold and the indoor temperature is greater than or equal to the set temperature, the heating controller controls the first mounting plate and the second mounting plate to rotate back to the first compartment and the second compartment respectively, and the heating controller controls the first heating element and the second heating element to stop; wherein, the second humidity threshold is less than the first temperature threshold.

[0081] In this embodiment, when the relative humidity is greater than or equal to the first humidity threshold, the humidity is too high and dehumidification is required.

[0082] Specifically, when the temperature difference is greater than zero and less than the first temperature threshold, the temperature difference is relatively small. In this case, the first and second mounting plates do not rotate, but the first and second heating elements are activated. Due to the ventilation holes, the first and second heating elements can still heat the flowing air, even though they are located in the first and second compartments respectively. This allows for an increase in the outlet air temperature without obstructing the airflow.

[0083] Specifically, when the temperature difference is greater than or equal to the first temperature threshold, the temperature difference is relatively large. At this time, the first and second mounting plates rotate towards the air outlet, and the first and second heating elements are activated. Thus, as air flows through the first and second heating elements, it is efficiently heated, and the indoor temperature rises rapidly.

[0084] When the relative humidity is below the second humidity threshold and the indoor temperature is greater than or equal to the set temperature, both humidity and temperature meet the user's temperature requirements, resulting in a more comfortable experience. At this time, the first and second heating elements rotate back into the first and second compartments, respectively. This avoids obstructing the normal airflow from the air conditioner.

[0085] Optionally, the first humidity threshold is 70% RH, and the second humidity threshold is 50% RH.

[0086] Optionally, when the air conditioner switches from heating mode to constant temperature dehumidification mode, the first temperature threshold is 0.5℃.

[0087] Optionally, when the air conditioner switches from cooling mode to constant temperature and dehumidification mode, the first temperature threshold is 1°C.

[0088] Optionally, the greater the temperature difference, the greater the rotation angle between the first and second mounting plates. For example... Figure 7 As shown, the rotation angle of the first mounting plate is α, and 0°≤α≤53°. The rotation angle of the second mounting plate is β, and 0°≤β≤65°.

[0089] In this embodiment, different rotation angles of the mounting plate result in varying heating effects on the flowing air. A larger temperature difference requires a larger rotation angle to ensure sufficient contact between the flowing air and the first and second heating elements, thereby rapidly increasing the outlet air temperature. Due to the limited space at the air outlet, limiting the ranges of α and β prevents interference between the first mounting plate, the second mounting plate, and the air guide plate.

[0090] Optionally, when the temperature difference exceeds the first temperature threshold, α increases by 10° for every 1° increase in temperature difference, and rotates to a maximum of 53°. Simultaneously, β increases by 10° for every 1° increase in temperature difference, and rotates to a maximum of 65°.

[0091] Optionally, the air guide plate has a first position, which corresponds to the air guide plate rotating to the center of the air outlet, such as... Figure 7 As shown. When the air guide plate rotates to the first position, within the range of α and β, the ventilation holes of the first mounting plate are opposite to the air guide plate, and the ventilation holes of the second mounting plate are opposite to the air guide plate. Furthermore, air flowing through the first mounting plate can be blown onto the air guide plate through the ventilation holes, and air flowing through the second mounting plate can also be blown onto the air guide plate through the ventilation holes. In this way, after being heated by the first and second heating sections, the air can be further heated by the third heating section, ensuring the heating effect of the third heating section.

[0092] Optionally, in steps S21 and S22, the air guide plate can be rotated to the first position, and the third heating unit is activated simultaneously.

[0093] like Figure 11 As shown in the embodiments of this disclosure, another method for controlling an air conditioner is also provided, including:

[0094] S10: The heating controller obtains the temperature difference between the set temperature and the indoor temperature, and obtains the indoor relative humidity;

[0095] S20: The heating controller controls the operating status of the first heating section and the second heating section based on the temperature difference and relative humidity.

[0096] S30: The heating controller controls the rotation angle of the air guide plate based on the temperature difference and relative humidity.

[0097] Optionally, such as Figure 12 As shown, in step S30, the heating controller controls the rotation angle of the air guide plate based on the temperature difference and relative humidity, including:

[0098] S31: When the relative humidity is greater than or equal to the first humidity threshold and the temperature difference is greater than or equal to the second temperature threshold, the heating controller controls the air guide plate to rotate until it is in contact with the first mounting plate; wherein, the second temperature threshold is greater than the first temperature threshold.

[0099] S32: When the indoor temperature rise rate is less than the preset rate, the heating controller controls the third heating unit to start.

[0100] In this embodiment, the air guide plate has a second position, which corresponds to the air guide plate rotating to a position where it is in contact with the first mounting plate, such as... Figure 8As shown. In step S31, the air guide plate rotates to the second position. Since the first mounting plate is located above the air outlet, it can guide the air downwards. In this way, under conditions of large temperature difference, downward airflow helps to quickly increase the indoor temperature.

[0101] In step S32, with the air outlet pointing downwards, the third heating element is activated to further increase the heating rate. At this time, the first, second, and third heating elements work together to rapidly increase the heating rate and further improve the constant temperature dehumidification effect.

[0102] Optionally, the second temperature threshold is 5.5°C.
