[0037] In order to facilitate understanding of the present invention, the indoor unit of the air conditioner provided by the embodiment of the present invention is first described. Figure 1-Figure 2 An embodiment of the present invention provides an indoor unit of an air conditioner, comprising: a heat exchanger 7, a first air duct 1, a second air duct 2, a variable air duct 3, a main air duct 4, a first crossflow fan blade 5, and a second crossflow fan blade 6. The heat exchanger 7 and the first crossflow fan blade 5 are arranged in the first air duct 1, and the second crossflow fan blade 6 is arranged in the second air duct 2. The outlets of the first air duct 1 and the second air duct 2 are respectively merged and connected with the main air duct 4, and the variable air duct 3 can be opened and closed to connect the first air duct 1 and the second air duct 2; wherein, when the variable air duct 3 is closed, the first air duct 1 and the second air duct 2 are independent of each other; when the variable air duct 3 is opened, the first air duct 1 and the second air duct 2 are connected to each other.

[0038] Specifically, Figure 1 and Figure 2This is a side view of an air conditioner indoor unit. The main air duct 4 is the air outlet duct for the air conditioner indoor unit, and air is blown out from the outlet of the main air duct 4. The first air duct 1 and the second air duct 2 are arranged adjacent to each other. The inlets of the first air duct 1 and the second air duct 2 both face the air inlet of the air conditioner indoor unit. The first air duct 1 and the second air duct 2 both extend in a streamlined shape toward the main air duct 4, and their outlets converge into the main air duct 4. A heat exchanger 7 is arranged in the first air duct 1, and a first crossflow blade 5 is arranged downstream of the heat exchanger 7. When the first crossflow blade 5 is operated, air enters the first air duct 1 from the air inlet of the air conditioner indoor unit, first exchanges heat on the surface of the heat exchanger 7, then flows into the main air duct 4, and finally blows out from the outlet of the main air duct 4. Only the second crossflow blade 6 is arranged in the second air duct 2. When the second crossflow blade 6 is operated, air enters the second air duct 2 from the air inlet of the air conditioner indoor unit, flows directly into the main air duct 4, and finally blows out from the outlet of the main air duct 4. Since the air in the first duct 1 passes through the surface of the heat exchanger 7 and undergoes heat exchange, the air in the first duct 1 is cold or hot air. However, there is no heat exchanger 7 in the second duct 2, and the air does not undergo heat exchange, so the air in the second duct 2 is air at room temperature. The first duct 1 and the second duct 2 are connected by the variable duct 3. The variable duct 3 can be opened and closed. Opening connects the first duct 1 and the second duct 2, and closing disconnects the first duct 1 and the second duct 2. When the variable duct 3 is opened, the first duct 1 and the second duct 2 are connected, so that the first duct 1 and the second duct 2 are connected. In this way, the air in the second duct 2 can flow into the first duct 1, and more air passes through the surface of the heat exchanger 7 for heat exchange, increasing the air flow through the heat exchanger 7, thereby achieving faster temperature reduction or temperature increase, quickly adjusting the temperature to the set temperature, achieving the purpose of rapid temperature control, and improving temperature control efficiency. When the variable air duct 3 is closed, the first air duct 1 and the second air duct 2 are disconnected, making the first air duct 1 and the second air duct 2 independent of each other. In this way, the air in the first air duct 1 is converted into cold air or hot air after heat exchange and enters the main air duct 4. The air in the second air duct 2 flows directly into the main air duct 4 as normal temperature air without heat exchange. The two air flows mix, neutralizing the air temperature, preventing the blown air from being too cold or too hot, and improving the comfort of the air outlet. It should be noted that there are many structures for the variable air duct 3. Regardless of the structure, as long as it can connect or separate the first air duct 1 and the second air duct 2, it is not limited here.

[0039] Through this embodiment, compared with the traditional air conditioner indoor unit with a single cross-flow fan blade, this embodiment, on the one hand, introduces room temperature air into the room and mixes it with the cold air or hot air that has undergone heat exchange, neutralizes the temperature, avoids direct blowing of cold air or hot air, and improves human comfort; on the other hand, it increases the flow rate of air flowing through the surface of the heat exchanger 7, accelerates the cooling or heating speed, and improves the temperature control efficiency.

[0040] Reference Figure 1and Figure 2 In one embodiment, the variable air duct 3 includes a switching channel 31 and a flow guide 32. The switching channel 31 connects the first air duct 1 and the second air duct 2. The flow guide 32 is rotatably disposed between the switching channel 31 and the second air duct 2. When the flow guide 32 rotates into the second air duct 2, the variable air duct 3 is opened; when the flow guide 32 rotates into the switching channel 31, the variable air duct 3 is closed. Specifically, the variable air duct 3 includes the switching channel 31 and the flow guide 32. The switching channel 31 serves as a fixed air duct structure connecting the first air duct 1 and the second air duct 2. The switching channel 31 allows communication between the first and second air ducts 1 and 2. The flow guide 32 can be disposed in the switching channel 31 or in the second air duct 2. The flow guide 32 is rotatable within the switching channel 31 and the second air duct 2. The rotation of the flow guide 32 can be driven by a motor, which can control the rotation angle of the flow guide 32 to facilitate rotation of the flow guide 32 to a suitable position. When the guide member 32 turns to the second air duct 2, the switching channel 31 will open, so that the switching channel 31 connects the first air duct 1 and the second air duct 2, and the first air duct 1 and the second air duct 2 are connected to each other. When the guide member 32 turns to the switching channel 31, the switching channel 31 is closed by the guide member 32, and the switching channel 31 will be closed, separating the first air duct 1 from the second air duct 2. The first air duct 1 and the second air duct 2 are independent of each other, and the air in the two air ducts does not affect each other. It should be noted that the structure of the guide member 32 can be various. No matter what structure it is, as long as it can rotate to change the direction of the airflow, it is not limited here. The opening and closing of the variable air duct 3 is achieved by the rotatable guide member 32, which has a simple structure, convenient drive control, and high reliability.

[0041] Reference Figure 1 and Figure 2In one embodiment, the second air duct 2 includes a first air guide wall 21 and a second air guide wall 22. The first air guide wall 21 and the second air guide wall 22 are spaced apart, and the second air guide wall 22 is adjacent to the switching channel 31. The second air guide wall 22 has an air guide opening 23 formed therein, and the second air duct 2 and the switching channel 31 are connected through the air guide opening 23. The air guide member 32 is rotatably mounted on the air guide opening 23. When the air guide member 32 rotates to close the air guide opening 23, the variable air duct 3 is closed. When the air guide member 32 rotates to abut against the first air guide wall 21, the variable air duct 3 is opened and the second air duct 2 is closed. Specifically, the first air guide wall 21 and the second air guide wall 22 are spaced apart, with a certain distance between them. The second air duct 2 is defined between the first air guide wall 21 and the second air guide wall 22, and the second crossflow blade 6 is disposed in the second air duct 2 near the air inlet of the indoor unit of the air conditioner. The second air duct 2 is adjacent to the first air duct 1, the second air guide wall 22 is located on the side close to the first air duct 1, and the first air guide wall 21 is located on the side away from the first air duct 1. A guide port 23 is provided on the second air guide wall 22, one end of the switching channel 31 is connected to the guide port 23, and the other end of the switching channel 31 is connected to the first air duct 1, so that air can enter the switching channel 31 from the second air duct 2 through the guide port 23 and then flow to the first air duct 1. The guide member 32 can be a guide vane, which is provided with a rotating shaft end and is controlled by a stepper motor to rotate around the rotating shaft end. The rotating shaft end of the guide vane is set on the guide port 23, and the area of ​​the guide vane matches the area of ​​the guide port 23. Under the drive of the motor, the guide vane can rotate to cover the guide port 23, closing the guide port 23, thereby closing the switching channel 31, and thus closing the variable air duct 3. In addition, the guide blades can also rotate in the opposite direction under the drive of the motor. The guide blades rotate toward the first air guide wall 21, open the guide port 23, rotate into the second air duct 2, and gradually open until they abut against the first air guide wall 21 and stop. In this way, the guide port 23 is opened and because the side of the guide blade away from the rotating shaft end abuts against the first air guide wall 21, the entire guide blade horizontally blocks the second air duct 2, so that the second air duct 2 is closed, and all the air enters the switching channel 31 from the guide port 23, and then enters the first air duct 1 from the switching channel 31. It can be seen that the guide member 32 has two positions in the air conditioner indoor unit, position one is on the guide port 23, and position two is in the second air duct 2. When the guide member 32 rotates to position one, the switching channel 31 is completely blocked, and the indoor air can enter the second air duct 2 through the second cross-flow fan blade 6. The second air duct 2 intersects with the first air duct 1 and converges into the main air duct 4; in the cooling mode, the higher temperature air in the second air duct 2 will be mixed with the lower temperature air in the first air duct 1 to obtain air with a more comfortable temperature, and finally blown out from the main air duct 4, thereby avoiding direct blowing of cold air.In heating mode, the cooler air in the second duct 2 mixes with the warmer air in the first duct 1, creating air at a more comfortable temperature before being blown out through the main duct 4, thus preventing direct hot air. When the guide vanes rotate to position 2, the second duct 2 is completely blocked, and the air at the indoor ambient temperature introduced by the second crossflow vanes 6 enters the switching channel 31, from which it is transported to the first duct 1. This increases the air flow through the heat exchanger 7, improving its overall utilization and enabling rapid regulation of the indoor ambient temperature.

[0042] Continue to refer to Figure 2 In one embodiment, the heat exchanger 7 includes a first heat exchange region 71 and a second heat exchange region 72. The first crossflow blade 5 is disposed downstream of the first heat exchange region 71, and one side of the second heat exchange region 72 is disposed toward the variable air duct 3. The heat exchange area of ​​the first heat exchange region 71 is larger than that of the second heat exchange region 72. Specifically, the heat exchanger 7 of this embodiment is a three-fold heat exchanger 7, wherein the first heat exchange region 71 is a two-fold region and the second heat exchange region 72 is a single-fold region. Therefore, the heat exchange area of ​​the first heat exchange region 71 is larger than that of the second heat exchange region 72. The first crossflow blade 5 is located below the first heat exchange region 7. When the first crossflow blade 5 is in operation, the air first passes through the first heat exchange region 71 for heat exchange before merging with the main air duct 4. One side of the second heat exchange region 72 faces the variable air duct 3. When the variable air duct 3 is open, the air in the second air duct 2 passes through the variable air duct 3 and then through the second heat exchange region 72. After heat exchange in the second heat exchange region 72, the air enters the first air duct 1 and finally flows to the main air duct 4. Compared to the traditional air conditioner indoor unit design with a single cross-flow blade, which results in a low air volume in part of the heat exchanger 7 and fails to fully utilize the area of ​​the heat exchanger 7, this embodiment utilizes a dual cross-flow blade structure in conjunction with the variable air duct 3. This utilizes both the double-folded first heat exchange region 71 and the single-folded second heat exchange region 72, fully utilizing the area of ​​the heat exchanger 7. The air at the indoor ambient temperature introduced by the second cross-flow blade 6 can fully enter the switching channel 31 and flow to the second heat exchange region 72, increasing the air flow in the second heat exchange region 72 and improving the overall utilization rate of the heat exchanger 7. This allows for rapid adjustment of the indoor ambient temperature, improves the efficiency of rapid cooling (heating), and significantly shortens the time to reach the set temperature.

[0043] In summary, this embodiment utilizes a dual crossflow blade design and a variable air duct 3. The first crossflow blade 5 primarily directs indoor air through the heat exchanger 7, achieving heat exchange. With the variable air duct 3, the second crossflow blade 6 has a dual function: in comfort mode, it draws in ambient temperature air to mix with cold (hot) air, and adjusts its rotational speed to deliver air at a moderate temperature. In rapid cooling mode, it increases the flow through the heat exchanger 7, achieving rapid indoor temperature control.

[0044] See also Figure 3 , Figure 3 This is a flow chart of the control method of the air conditioner provided by the embodiment of the present invention. The air conditioner indoor unit applied to the above embodiment has been described in detail in the above embodiment. For the sake of brevity of the description, it will not be repeated here. The control method of the air conditioner is described in detail below. Figure 3 As shown, the method includes the following steps: S110-S130.

[0045] S110, receiving an air conditioning mode instruction;

[0046] S120: If the air conditioning mode instruction is the comfortable wind mode, control the variable air duct 3 to be closed;

[0047] S130: If the air conditioning mode instruction is the rapid heat exchange mode, control the variable air duct 3 to open.

[0048] In this embodiment, the air conditioning cooling modes include comfort mode and rapid heat exchange mode. The user can initiate a command signal using a remote control, and the air conditioner receives the command signal. Comfort mode is a mode in which the air temperature of the air conditioner is suitable for comfort. Rapid heat exchange mode is a mode in which the indoor temperature needs to be quickly adjusted, requiring high cooling or heating capacity. When the air conditioning mode command is comfort mode, the variable air duct 3 is controlled to close. Specifically, the motor controls the air guide 32 to rotate to position 1. The air guide 32 closes the air guide opening 23 and closes the switching channel 31, thereby isolating the first air duct 1 and the second air duct 2, making them independent of each other. The ambient temperature air in the second air duct 2 is then drawn into the main air duct 4 by the operation of the second crossflow blades 6. There, the air mixes with the cold or hot air in the first air duct 1, neutralizing the temperature. This ensures that the air flowing out of the main air duct 4 is at a suitable temperature, neither too cold nor too hot, preventing direct blow-by of cold or hot air and improving airflow comfort. When the air conditioning mode is cooling in the rapid heat exchange mode, the variable air duct 3 is controlled to open, that is, the guide member 32 is controlled by the motor to rotate to position two, the guide member 32 opens the guide port 23 and seals the second air duct 2, and the switching channel 31 is opened, so that the first air duct 1 and the second air duct 2 are connected to each other. Then, the normal temperature air in the second air duct 2 all enters the first air duct 1 through the switching channel 31 under the operation of the second cross-flow fan blade 6 and flows to the folding area of ​​the heat exchanger 7, which makes full use of the area of ​​the heat exchanger 7, so that more air is heat-exchanged, and the flow rate of air flowing through the heat exchanger 7 is increased, which can achieve rapid cooling or heating and improve the temperature regulation efficiency.

[0049] In one embodiment, if Figure 4 As shown, after step S120, the following steps are also included: S140-S160.

[0050] S140: Acquire a first temperature in the first air duct 1 and a second temperature in the second air duct 2, and acquire a first wind speed in the first air duct 1 using a first wind speed sensor, and acquire a cross-sectional area of ​​the first wind speed sensor;

[0051] S150, receiving a target set temperature, and determining a target flow rate of the second air duct 2 according to a preset flow rate formula based on the first temperature, the second temperature, the first wind speed, the cross-sectional area, and the target set temperature;

[0052] S160 , converting the speed according to the target flow rate to determine a target speed of the second cross flow blade 6 , and controlling the operation of the second cross flow blade 6 according to the target speed.

[0053] Specifically, a first wind speed sensor and a temperature sensor are provided in the first air duct 1. The first wind speed sensor is used to detect the first wind speed V1 in the first air duct 1. The cross-sectional area S1 of the first wind speed sensor is a design parameter and can be directly obtained without measurement. The temperature sensor is used to detect the air temperature in the first air duct 1 as the first temperature T1. The air temperature in the second air duct 2 is approximately the indoor ambient temperature and can be measured by the indoor ambient temperature sensing package as the second temperature T2. The target setting temperature T is the temperature set by the user and can be set by the remote control. The air conditioner indoor unit receives the target setting temperature set by the user. After obtaining T1, T2, V1, S1 and receiving T, the required target flow Q of the second air duct 2 can be calculated by the preset flow formula, so as to achieve the air with the target setting temperature set by the final user. That is, if the target setting temperature T is to be reached, the second air duct is required to provide air with a target flow Q to mix with the air in the first air duct 1. Among them, the preset flow formula is as follows:

[0054]

[0055] Among them, Q is the target speed, T is the target set temperature, T1 is the first temperature, T2 is the second temperature, V1 is the first wind speed, and S1 is the cross-sectional area of ​​the first wind speed sensor. T is input into the preset flow formula for calculation, and the target flow Q can be obtained through the preset flow formula. The target flow Q is related to the speed of the second cross-flow fan blade 6. Before the air conditioner is shipped, the designer obtains the relationship between the speed n of the second cross-flow fan blade 6 and the flow of the second air duct 2 through experiments, Q=f(n). During actual operation, the air conditioner will query the corresponding speed n of the second cross-flow fan blade 6 according to the calculated Q, and send a signal to adjust the speed of the second cross-flow fan blade 6 in real time. Finally, the air in the second air duct 2 will be mixed with the air in the first air duct 1 to obtain air with the user-set temperature, which will be blown out from the main air duct 4. Through this embodiment, the speed of the second cross-flow fan blade 6 can be flexibly adjusted according to the target set temperature set by the user to achieve a specific air outlet temperature, improve user comfort, and have a high degree of intelligence.

[0056] For example, assume that the above parameters T is 27°C, T1 is 25°C, T2 is 30°C, V1 is 2m / s, and S1 is 0.1m 2 , calculated by the preset flow formula, Q = 0.1333m 3 / s, according to the relationship between the rotation speed n of the second crossflow blade 6 and the flow rate Q of the second air duct 2, it is assumed that this relationship has been determined by the designer through experiments and recorded in a lookup table. For example, for every increase of 0.1m 3 / s flow demand, the speed of the second cross flow fan blade 6 needs to be increased by 100RPM. Based on this, in order to achieve 0.1333m 3 / s target flow rate, the speed of the second crossflow blades 6 should be increased accordingly by approximately 133 RPM (the actual value depends on the specific lookup table data).
