[0015] Some embodiments of the present disclosure provide an air conditioner.

[0016] As shown in FIG. 1, the air conditioner 1 includes an indoor unit 60 and an outdoor unit 40. The indoor unit 60 and the outdoor unit 40 are connected via piping to transmit a refrigerant. The indoor unit 60 includes an indoor heat exchanger 400 and an indoor fan 600. The outdoor unit 40 includes a compressor 201, a four-way valve 202, an outdoor heat exchanger 203, an outdoor fan 204, and an expansion valve 205. The compressor 201, the outdoor heat exchanger 203, the expansion valve 205, and the indoor heat exchanger 400 connected in order form a refrigerant circuit, and the refrigerant flows cyclically in the refrigerant circuit and exchanges heat with the air via the outdoor heat exchanger 203 and the indoor heat exchanger 400, respectively, to realize the cooling mode or the heating mode of the air conditioner 1.

[0017] The compressor 201 is configured to compress a refrigerant, thereby compressing a low pressure refrigerant to form a high pressure refrigerant.

[0018] The outdoor heat exchanger 203 is configured to exchange heat between the outdoor air and the refrigerant transmitted within the outdoor heat exchanger 203. For example, in a cooling mode of the air conditioner 1, the outdoor heat exchanger 203 operates as a condenser, so that the refrigerant compressed by the compressor 201 releases heat to the outdoor air via the outdoor heat exchanger 203 and condenses. In a heating mode of the air conditioner 1, the outdoor heat exchanger 203 operates as an evaporator, so that the refrigerant after decompression absorbs heat from the outdoor air via the outdoor heat exchanger 203 and evaporates.

[0019] In some embodiments, the outdoor heat exchanger 203 further includes heat exchange fins, which increase the contact area between the outdoor air and the refrigerant transported within the outdoor heat exchanger 203, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0020] The outdoor fan 204 is configured to draw outdoor air into the outdoor unit 40 through a second suction port of the outdoor unit 40, and send out the outdoor air that has exchanged heat with the outdoor heat exchanger 203 through a third air outlet of the outdoor unit 40. The outdoor fan 204 supplies power to the flow of the outdoor air.

[0021] The expansion valve 205 is connected between the outdoor heat exchanger 203 and the indoor heat exchanger 400, and adjusts the flow rate of the refrigerant flowing between the outdoor heat exchanger 203 and the indoor heat exchanger 400 by adjusting the opening degree of the expansion valve 205. The flow rate and pressure of the refrigerant flowing between the outdoor heat exchanger 203 and the indoor heat exchanger 400 affect the heat exchange performance of the outdoor heat exchanger 203 and the indoor heat exchanger 400. The expansion valve 205 may be an electronic valve. The opening degree of the expansion valve 205 is adjustable to control the flow rate and pressure of the refrigerant flowing through the expansion valve 205.

[0022] The four-way valve 202 is connected in the refrigerant circuit, and is configured to switch the flow direction of the refrigerant in the refrigerant circuit to cause the air conditioner 1 to operate in a cooling mode or a heating mode.

[0023] The indoor heat exchanger 400 is configured to exchange heat between the indoor air and the refrigerant transferred within the indoor heat exchanger 400. For example, in the cooling mode of the air conditioner 1, the indoor heat exchanger 400 operates as an evaporator, so that the refrigerant that has released heat through the outdoor heat exchanger 203 absorbs heat from the indoor air through the indoor heat exchanger 400 and evaporates. In the heating mode of the air conditioner 1, the indoor heat exchanger 400 operates as a condenser, so that the refrigerant that has absorbed heat through the outdoor heat exchanger 203 releases heat to the indoor air through the indoor heat exchanger 400 and condenses.

[0024] In some embodiments, the indoor heat exchanger 400 further includes heat exchange fins, which increase the contact area between the indoor air and the refrigerant transported within the indoor heat exchanger 400, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0025] The indoor fan 600 is configured to draw indoor air into the indoor unit 60 through a third suction port of the indoor unit 60, and send out the indoor air that has exchanged heat with the indoor heat exchanger 400 through a fourth air outlet of the indoor unit 60. The indoor fan 600 supplies power to the flow of indoor air.

[0026] The air conditioner 1 further includes a control device 50. The control device 50 is configured to control the operating frequency of the compressor 201, the opening degree of the expansion valve 205, the rotation speed of the outdoor fan 204, and the rotation speed of the indoor fan 600. The control device 50 is connected to the compressor 201, the expansion valve 205, the outdoor fan 204, and the indoor fan 600 via data lines, and transmits communication information.

[0027] The controller 50 includes a processor. The processor may include a Central Processing Unit (CPU), a microprocessor, or an Application Specific Integrated Circuit (ASIC), and may be configured to perform the corresponding operations described in the controller 50 when the processor executes a program stored in a non-transitory computer-readable medium coupled to the controller 50. The non-transitory computer-readable storage medium may include a magnetic storage device (e.g., a hard disk, a floppy disk, or a magnetic tape), a smart card, or a flash memory device (e.g., an Erasable Programmable Read-Only Memory (EPROM), a card, a stick, or a keyboard driver).

[0028] In general, control of the airflow discharged by an air conditioner is achieved by the following installation: A wind guide plate is installed horizontally and outside the air outlet, and the wind is swept up and down by rotating the wind guide plate. Vertical guide blades are built into the air conditioner, and the wind is swept left and right. The air conditioner installs a wind plate with fine holes horizontally, and the airflow passes through the holes on the wind plate at a low speed. A wind shield can be installed in front of the air conditioner, allowing the wind to come out from around the air conditioner.

[0029] However, the airflow from the air outlet of the air conditioner installed as described above is blown out in a specific direction along a straight line, and the blowing pattern is uniform. Since the airflow is blown out in a specific direction along a straight line and is bundled, the wind feels like it is being swept out, and the user's comfort is relatively poor. In addition, since the bundled wind makes the indoor airflow flow pattern uniform, it is not possible to generate a comfortable wind field in which the wind speed and direction change transiently. In addition, the blowing pattern of the air conditioner is uniform, the wind mixing efficiency is low, and energy consumption is high.

[0030] As shown in FIG. 2 to FIG. 4, the air conditioner 1 further includes a vibrator 20. As shown in FIG. 2, the vibrator 20 includes a housing 21 and at least one partition plate 22. The housing 21 can play a role of sealing, and prevent leakage when the airflow flows through the vibrator 20. As shown in FIG. 2, one side of the housing 21 has a first suction port 23, and the side of the housing 21 opposite to the one side has a first outlet port 24. There is a cavity 25 in the housing 21, and the cavity 25 communicates with the first suction port 23 and the first outlet port 24, so that the airflow can enter the cavity 25 through the first suction port 23 and then exit from the first outlet port 24. At least one partition plate 22 is installed in the cavity 25, and the airflow is deflected when flowing through the at least one partition plate 22, forming a vortex in the vicinity of the partition plate 22, thereby realizing the vibration blowing of the vibrator 20. In this way, the vibrator 20, instead of the air guide plate, can achieve self-oscillating airflow up and down from the first air outlet 24 when the air guide plate is fixed and does not move, improving the mixing efficiency of the airflow discharged from the air conditioner 1 and the indoor air, changing the indoor airflow distribution, and preventing the air conditioner 1 from blowing out along a straight line, thereby achieving a natural and comfortable air blowing effect of the air conditioner 1. Note that vortexes are a phenomenon of airflow circulation.

[0031] 2, after at least one partition plate 22 is installed in the cavity 25, the cavity 25 may be divided into a mainstream passage 26 and at least one return passage 27. One end of the mainstream passage 26 is installed facing the first suction port 23, and the other end of the mainstream passage 26 is installed facing the first blow-out port 24. The return passage 27 is located on the side of the at least one partition plate 22 facing the mainstream passage 26. An inlet 28 of the return passage 27 is formed between one end of the partition plate 22 close to the first blow-out port 24 and the housing 21, and an outlet 29 of the return passage 27 is formed between one end of the partition plate 22 close to the first suction port 23 and the housing 21. That is, a part of the airflow enters the mainstream passage 26 via the first intake port 23 and then flows in the direction toward the first outlet 24, and another part of the airflow enters the return passage 27 from the inlet 28 of the return passage 27 due to the blocking of the housing 21 as it flows to the first outlet 24, and then returns to the mainstream passage 26 from the outlet 29 of the return passage 27.

[0032] 2, the partition plate 22 includes a first flow guide segment 30, and the central axis of the first flow guide segment 30 is located on the side of the arc plate away from the housing 21. As a result, after the airflow in the return passage 27 returns to the mainstream passage 26, the flow direction of part of the airflow in the mainstream passage 26 can be deflected, and the first flow guide segment 30 can play a role in guiding the airflow, so that the other part of the airflow in the mainstream passage 26 flows in the partition plate 22 in the opposite direction to the direction toward the first suction port 23, generating a vortex.

[0033] In the following, the flow of airflow in the cavity 25 will be described using an example in which the vibrator 20 includes two partition plates 22. For convenience of explanation, unless otherwise specified, the upper and lower directions in this disclosure refer to the upper and lower directions in FIG. 2. The two partition plates 22 are arranged along a direction perpendicular to the connection line between the first intake port 23 and the first exhaust port 24, and for example, the two partition plates 22 are arranged above and below. The two partition plates 22 are installed symmetrically with respect to the central axis line of the cavity 25. In this way, when the airflow passes through the two partition plates 22 and is deflected, the difference in airflow flow rate between the upper and lower sides can be reduced.

[0034] 3 and 4, when the airflow travels from the first suction port 23 along the central axis of the cavity 25 to the vicinity of the first air outlet 24, a part of the airflow flows along the inner wall of the housing 21 and enters the inlet 28 of the return passage 27. Due to the non-uniformity of the flow, the flow rates of the airflow at the inlets 28 of the different return passages 27 are different. For example, the flow rate of the airflow passing through the upper return passage 27 is greater than the flow rate of the airflow passing through the lower return passage 27, so the flow rates at the outlets 29 of the different return passages 27 are also different, and the airflow from the mainstream passage 26 is pushed and deflected at the outlet 29 of the return passage 27 by the airflows with different flow rates on the upper and lower sides.

[0035] 4, the portion of the deflected airflow close to the lower partition plate 22 flows along the surface of the lower partition plate 22 (in the direction of arrow A in FIG. 4), while the portion of the deflected airflow close to the upper partition plate 22 flows in the direction opposite to the direction toward the first air inlet 23 (in the direction of arrow B in FIG. 4), generating a vortex, which pushes the airflow in the main passage 26 toward the lower partition plate 22. In this case, the airflow in the first air outlet 24 flows downward.

[0036] The airflow in the main passage 26 is pushed out towards the lower partition plate 22, and the flow rate of the airflow at the inlet 28 of the lower return passage 27 becomes larger than the flow rate of the airflow at the inlet 28 of the upper return passage 27, so that the flow rates of the airflow at the inlets 28 of the return passages 27 on both sides change periodically. That is, the flow rate of the airflow at the inlet 28 of the upper return passage 27 is larger than the flow rate of the airflow at the inlet 28 of the lower return passage 27, and after a certain time has passed, the flow rate of the airflow at the inlet 28 of the upper return passage 27 becomes smaller than the flow rate of the airflow at the inlet 28 of the lower return passage 27, and after a certain time has passed, the flow rate of the airflow at the inlet 28 of the upper return passage 27 again becomes larger than the flow rate of the airflow at the inlet 28 of the lower return passage 27, and so on in this manner.

[0037] As shown in FIG. 2, the partition plate 22 further includes a first air guide segment 31 and a second air guide segment 32. One end of the first air guide segment 31 is connected to one end of the first flow guide segment 30, and the other end of the first air guide segment 31 extends in a direction toward the first suction port 23, thereby ensuring that the airflow is deflected along the first air guide segment 31 after entering the cavity 25. One end of the second air guide segment 32 is connected to the other end of the first flow guide segment 30, and the other end of the second air guide segment 32 extends in a direction toward the first air outlet 24, thereby making it easier for the airflow to be guided along the second air guide segment 32 to the first air outlet 24, and then to be discharged from the first air outlet 24. An outlet 29 of the return passage 27 is formed between the other end of the first air guide segment 31 and the housing 21, and an inlet 28 of the return passage 27 is formed between the other end of the second air guide segment 32 and the housing 21.

[0038] The vibrator 20 further includes a first converging segment 37. The first converging segment 37 engages with the first suction port 23, and the centerline of the first converging segment 37 overlaps with the centerline of the first suction port 23. The cross-sectional area of ​​the first converging segment 37 gradually decreases in a direction from the outside of the housing 21 toward the cavity 25, so that the airflow is collected after entering the cavity 25 from the first suction port 23, and the airflow is prevented from diverging.

[0039] 2, one end of the first contraction segment 37 close to the cavity 25 is the first end 160, one end of the first air guide segment 31 close to the first suction port 23 is the second end 33, the diameter of the first end 160 is a, the distance between the second ends 33 of the two partition plates 22 is b, and a is smaller than b. In this way, the airflow can be deflected in a direction toward the first air guide segment 31 after entering the cavity 25, thereby ensuring the deflection space after the airflow enters the mainstream passage 26.

[0040] 2, one end where the first air guide segment 30 and the first air guide segment 31 are connected is defined as a third end 34, the distance between the third ends 34 of the two partition plates 22 is defined as c, and b is smaller than c. In this way, when the airflow flows along the main passage 26, the deflection space of the airflow can be made sufficiently large.

[0041] 2, the cross section of the housing 21 on the side closer to the first air outlet 24 is arc-shaped, and the portion of the housing 21 with the arc-shaped cross section is the second flow guide segment 36, the center of the arc is located on the side of the second flow guide segment 36 closer to the cavity 25, and the cross-sectional area of ​​the second flow guide segment 36 gradually decreases in the direction from the cavity 25 toward the first air outlet 24. In this way, a portion of the airflow flows along the surface of the second flow guide segment 36 and is guided to the inlet 28 of the return passage 27, and thereby can enter the return passage 27.

[0042] 2, the vibrator 20 further includes a second contraction segment 35. The shape of the second contraction segment 35 is trumpet-shaped, the second contraction segment 35 is installed at the first air outlet 24, the center line of the second contraction segment 35 overlaps with the center line of the first air outlet 24, and the cross-sectional area of ​​the second contraction segment 35 gradually increases from the cavity 25 to the outside of the housing 21, so that the airflow flows out along the inner wall of the second contraction segment 35, which allows the airflow to flow out smoothly along different angles, and reduces the resistance at the first air outlet 24.

[0043] Since the extension line of the second air guide segment 32 does not intersect with the connection between the second flow guide segment 36 and the second contraction segment 35, the second air guide segment 32 can be prevented from affecting the wind flow at the connection between the second flow guide segment 36 and the second contraction segment 35.

[0044] 2 and 5, the air conditioner 1 further includes an air passage member 10, and the indoor heat exchanger 400 is installed in the air passage member 10, which is an inflow and outflow passage for the airflow. The airflow enters the air passage member 10, exchanges heat with the indoor heat exchanger, and is then discharged into the room, thereby achieving the effects of cooling and heating.

[0045] As shown in Fig. 2 and Fig. 5, the air conditioner 1 further includes a blower 11, which is installed in the air passage member 10 and is used to draw the airflow outside the air conditioner 1 into the air passage member 10. The air passage member 10 has a second air outlet 12, and the airflow after heat exchange can be discharged indoors through the second air outlet 12. In addition, the cross-sectional area of ​​the side of the air passage member 10 closer to the second air outlet 12 gradually decreases in the direction toward the second air outlet 12, and the airflow of the second air outlet 12 can be collected. The air passage member 10 is installed on the side closer to the first air inlet 23 of the housing 21, and the first air inlet 23 of the vibrator 20 communicates with the second air inlet 12.

[0046] 2 and 5, air passage member 10 includes first air passage wall 13 and second air passage wall 14. First air passage wall 13 is disposed opposite second air passage wall 14, and second air outlet 12 is defined between first air passage wall 13 and second air passage wall 14. Thus, airflow in air passage member 10 passes between first air passage wall 13 and second air passage wall 14 and can enter vibrator 20 through second air outlet 12. The cross-sectional areas of first air passage wall 13 and second air passage wall 14 both gradually decrease in the direction toward second air outlet 12.

[0047] 2 and 5, one end of the first air passage wall 13 away from the second air outlet 12 is a fourth end 130, one end of the second air passage wall 14 away from the second air outlet 12 is a fifth end 140, and the involute of the rear spiral casing of the blower 11 is located at the tip of the fifth end 140, thereby reducing the effect of the blower 11 on the airflow between the first air passage wall 13 and the second air passage wall 14. The connection line between the fourth end 130 and the fifth end 140 is perpendicular to the first air passage wall 13, so that the airflow can be smoothly introduced between the first air passage wall 13 and the second air passage wall 14.

[0048] The end of the first air passage wall 13 close to the second air outlet 12 is designated as the sixth end 131, the end of the second air passage wall 14 close to the second air outlet 12 is designated as the seventh end 141, the distance between the fourth end 130 and the fifth end 140 is designated as d, and the distance between the sixth end 131 and the seventh end 141 is designated as f, where f is smaller than d. This realizes that the cross-sectional areas of the first air passage wall 13 and the second air passage wall 14 gradually decrease in the direction toward the second air outlet 12.

[0049] In addition, as shown in Figures 2 and 5, since f is smaller than b, the airflow can be deflected in a direction toward the first air guide segment 31 after entering the cavity 25, thereby ensuring the deflection space after the airflow enters the main passage 26.

[0050] As shown in FIG. 5, FIG. 7 and FIG. 8, at least one partition plate 22 is movably installed in the cavity 25. After the at least one partition plate 22 moves, the outlet 29 of the return passage 27 on one side in the cavity 25 decreases, and the outlet 29 of the return passage 27 on the other side in the cavity 25 increases, and the airflow flows in through the outlet 29 of the return passage 27 on the other side in the cavity 25. In the following, the flow principle of the airflow in the cavity 25 when the two partition plates 22 rotate together clockwise along one point on the center line of the cavity 25 in the cavity 25 will be described by taking the case where the vibrator 20 includes two partition plates 22 as an example. Of course, one of the two partition plates 22 may rotate and the other of the two partition plates 22 may be fixed and not move. In addition, the motion of the two partition plates 22 is not limited to a rotational motion, and the two partition plates 22 may move.

[0051] 5, 7 and 8, when the airflow passes through the first suction port 23, the two partitions 22 are rotated to a set angle, so that one end of the upper partition 22 close to the first suction port 23 gradually approaches the housing 21, thereby reducing the outlet 29 of the upper return passage 27, and the lower partition 22 is rotated to a position facing the first suction port 23, so that the lower partition 22 performs a certain blocking effect on the airflow. In this way, a small portion of the airflow passes through the upper return passage 27, while the majority of the airflow moves along the side of the lower partition 22 close to the housing 21, i.e., passes through the outlet 29 of the lower return passage 27 and flows out from the inlet 28 of the lower return passage 27, changing the flow of the airflow from a flow biased downward to a flow biased upward. Also, a small portion of the airflow moves along the side of the upper partition plate 22 that is closer to the main passage 26, and this portion of the airflow merges with the airflow passing through the lower return passage 27 at the first air outlet 24, and moves biased upward through the first air outlet 24. Similarly, when both partition plates 22 rotate counterclockwise, the airflow moves biased downward through the first air outlet 24. In this way, it is possible to realize the movement of the airflow in a predetermined direction, and this makes it possible to reduce the flow range of the airflow when it passes through the first air outlet 24, and when the flow rate of the airflow is constant, it is possible to increase the flow speed of the airflow at the first air outlet 24, and this makes it possible to blow air in a predetermined direction over a long distance.

[0052] As shown in Figures 5, 7 and 8, at least one partition plate 22 is rotatable relative to the housing 21, and after at least one partition plate 22 rotates, one end of the partition plate 22 located on one side of the cavity 25 near the first suction port 23 abuts against the housing 21, thereby closing the outlet 29 of the return passage 27 on one side of the cavity 25, thereby preventing the airflow from passing through the return passage 27 on the one side of the cavity 25, and most of the airflow chooses to pass through the return passage 27 on the other side of the cavity 25, thereby avoiding the interference of the airflow passing through the return passage 27 on one side of the cavity 25, and improving the effect of the airflow movement in a specified direction.

[0053] For example, when one end of upper partition plate 22 close to first suction port 23 abuts against housing 21, the airflow is blown upward in a predetermined direction at the position of air outlet 24. When one end of lower partition plate 22 close to first suction port 23 abuts against housing 21, the airflow is blown downward in a predetermined direction at the position of air outlet 24.

[0054] 6, the air conditioner 1 further includes a control device 50. The control device 50 is coupled to the blower 11 and at least one partition plate 22 to control the rotation speed of the blower 11 and to control the rotation of the at least one partition plate 22 relative to the housing 21.

[0055] The blowing modes of the air conditioner include a vibration blowing mode and a predetermined direction blowing mode. In the vibration blowing mode, the partition plate 22 of the fluid vibrator 20 is in a position to vibrate the airflow. In this case, one end of the partition plate 22 close to the first suction port 23 is separated from the housing 21, and the wind flowing through the first blowing port 24 diffuses toward the outside of the first blowing port 24, and the wind direction and wind speed are oscillated and changed at a certain frequency. In the predetermined direction blowing mode, one end of the partition plate 22 close to the first suction port 23 abuts against the housing 21, thereby closing the outlet 29 of the return passage 27 on the side close to the partition plate 22 in the cavity 25. The predetermined direction blowing mode includes upward blowing in a predetermined direction and downward blowing in a predetermined direction. The upward blowing in a predetermined direction refers to the wind direction of the first blowing port 24 being biased upward in the horizontal direction, that is, in an indoor environment, the wind from the first blowing port 24 blows toward the ceiling. The downward blowing in a predetermined direction means that the airflow direction from first air outlet 24 is biased toward the vertical direction or is close to the vertical direction; that is, in an indoor environment, the airflow from first air outlet 24 blows toward the floor.

[0056] The control device 50 is configured in the following manner.

[0057] By determining whether or not the current position of the partition plate 22 is a position that causes the airflow to oscillate, it is possible to determine whether or not the blowing mode is the vibration blowing mode.

[0058] If the current position of the partition plate 22 is not a position that causes the airflow to oscillate, the partition plate 22 is controlled to rotate to a position that causes the airflow to oscillate, in which case the blowing mode of the air conditioner 1 is switched to the oscillating blowing mode.

[0059] When the current position of the partition plate 22 is at a position that oscillates the airflow, the rotation speed of the blower 11 is controlled according to the absolute value of the difference between the temperature set by the user and the current indoor temperature, thereby adjusting the wind speed of the oscillating blowout. When the absolute value of the difference between the temperature set by the user and the current indoor temperature is equal to or greater than a first threshold, the control device 50 controls the rotation speed of the blower 11 to increase, thereby rapidly decreasing the absolute value of the difference between the temperature set by the user and the current indoor temperature, so that the indoor temperature reaches the set value. When the absolute value of the difference between the temperature set by the user and the current indoor temperature is equal to or less than a second threshold, the control device 50 controls the rotation speed of the blower 11 to decrease, thereby preventing the indoor temperature from becoming too low or too high, and maintaining the indoor temperature close to the set value. The first threshold is greater than the second threshold. The first air outlet 24 of the air conditioner 1 generates upward low-frequency oscillating wind and downward low-frequency oscillating wind, and the oscillation frequency shows a positive correlation with the blowing speed. By controlling the rotational speed of the blower 11 according to the absolute value of the difference between the temperature set by the user and the current indoor temperature, the wind speed at the first air outlet 24 can be better controlled, and a vortex caused by the up and down oscillating wind can be generated in the indoor wind field. As a result, the blown airflow, which has a certain temperature difference from the room temperature, can be efficiently mixed with the indoor air, reducing the temperature difference of the blown air.

[0060] The air conditioner 1 may be set to enter the oscillating blowing mode by default when started up, which effectively reduces the temperature difference of the blown air and prevents a decrease in the user experience due to a sudden change in temperature.

[0061] The control device 50 is further configured to operate the blower 11 at a first set rotation speed when the absolute value of the difference between the temperature set by the user and the current indoor temperature is equal to or less than a first set temperature. This allows the temperature difference of the blown air to be reduced relatively accurately, eliminating the conventional mechanical and straight blowing feeling, and achieving the purpose of natural and comfortable blowing. For example, the first set temperature may be 2°C, and the first set rotation speed may be 600 revolutions per minute (RPM).

[0062] In addition, the control device 50 is further configured to operate the blower 11 at a second set rotation speed when the absolute value of the difference between the temperature set by the user and the current indoor temperature is greater than the first set temperature and is equal to or less than the second set temperature. The second set temperature is greater than the first set temperature, and the second set rotation speed is greater than the first set rotation speed. For example, the second set temperature may be 3° C., and the second set rotation speed may be 900 RPM.

[0063] In addition, the control device 50 is further configured to operate the blower 11 at a third set rotation speed when the absolute value of the difference between the temperature set by the user and the current indoor temperature is greater than the second set temperature and is equal to or less than the third set temperature. The third set temperature is greater than the second set temperature, and the third set rotation speed is greater than the second set rotation speed. The second set temperature may be 5° C., and the second set rotation speed may be 1100 RPM.

[0064] As shown in FIG. 9, the control device 50 includes a decision assembly 51, a judgment assembly 52, and a control assembly 53, which are connected in sequence. The decision assembly 51 is used to decide whether the air conditioner 1 enters a quick cooling mode or a quick heating mode. In the quick cooling mode, the air conditioner 1 blows air at a high wind speed in the cooling mode, thereby realizing the effect of rapidly lowering the room temperature. In the quick heating mode, the air conditioner 1 blows air at a high wind speed in the heating mode, thereby realizing the effect of rapidly raising the room temperature. The decision assembly 52 is used to determine whether the blowing mode of the air conditioner 1 is the vibration blowing mode. The control assembly 53 is used to switch the blowing mode of the air conditioner 1 to the vibration blowing mode when the blowing mode of the air conditioner 1 is not the vibration blowing mode. That is, the control assembly 53 controls the occurrence of vibration changes in the blowing direction and wind speed of the first blowing port 24 by the partition plate 22 of the vibrator 20 being in a position that vibrates the airflow. When the air conditioner 1 is in the vibration air outlet mode, the control device 50 controls the air outlet direction of the air conditioner 1 and the rotational speed of the blower 11 according to the absolute value of the difference between the temperature set by the user and the current indoor temperature, thereby rapidly mixing the airflow with a high temperature difference at the first air outlet 24 with the indoor air.

[0065] As shown in FIG. 10, when at least one partition plate 22 moves, the control method for the air conditioner 1 includes the following steps.

[0066] Step S1: The control device 50 judges whether the current position of the partition plate 22 is in a position that vibrates the airflow, and if the current position of the partition plate 22 is not in a position that vibrates the airflow, executes step S2. If the current position of the partition plate 22 is in a position that vibrates the airflow, executes step S3.

[0067] Step S2: The control device 50 controls the partition plate 22 to rotate to a position where the partition plate 22 vibrates the airflow.

[0068] Step S3: The control device 50 adjusts the wind speed of the vibration blowing by controlling the rotation speed of the blower 11 according to the absolute value of the difference between the temperature set by the user and the current indoor temperature.

[0069] As shown in FIG. 11, step S3 includes steps S311 to S315.

[0070] Step S311: The control device 50 judges whether the absolute value of the difference between the temperature set by the user and the current room temperature is equal to or less than the first set temperature, and if the absolute value of the difference between the temperature set by the user and the current room temperature is equal to or less than the first set temperature, executes step S312. If the absolute value of the difference between the temperature set by the user and the current room temperature is not equal to or less than the first set temperature, executes step S313.

[0071] Step S312: The control device 50 controls the blower 11 to operate at the first set rotation speed.

[0072] Step S313: The control device 50 judges whether the absolute value of the difference between the temperature set by the user and the current room temperature is equal to or less than the second set temperature, and if the absolute value of the difference between the temperature set by the user and the current room temperature is equal to or less than the second set temperature, executes step S314. If the absolute value of the difference between the temperature set by the user and the current room temperature is not equal to or less than the second set temperature, executes step S315.

[0073] Step S314: The control device 50 controls the blower 11 to operate at the second set rotation speed.

[0074] Step S315: If the absolute value of the difference between the temperature set by the user and the current indoor temperature is equal to or less than the third set temperature, the control device 50 controls the blower 11 to operate at a third set rotation speed, which is higher than the second set temperature and higher than the second set rotation speed.

[0075] As shown in FIG. 12, when at least one partition plate 22 moves, step S1 includes step S11.

[0076] Step S11: When the air conditioner 1 receives a first command (quick cooling command) or a second command (quick heating command), i.e., when the control device 50 determines that the operation mode of the air conditioner 1 is the quick cooling mode or the quick heating mode, the control device 50 judges whether the position of the partition plate 22 is in a position that causes the airflow to oscillate. For example, the user may send a quick cooling command or a quick heating command to the air conditioner 1 via a "quick cooling" or "quick heating" button on the remote control.

[0077] In some embodiments, when the operation mode of the air conditioner 1 is switched to the fast cooling mode and the blowing direction is upward blowing in a predetermined direction, the blowing mode realizes sinking type cool air, and prevents the cool air blown out from the first air outlet 24 from "blow straight" to the user, thereby preventing the user from feeling uncomfortable. When the operation mode of the air conditioner 1 is the fast heating mode and the blowing direction is downward blowing in a predetermined direction, the hot air blown out from the first air outlet 24 moves downward, and rapidly raises the indoor temperature to the target temperature set by the user.

[0078] After the operating mode of the air conditioner 1 is switched to the fast cooling mode or the fast heating mode, if a high temperature difference exists at the first air outlet 24, and the operating mode of the air conditioner 1 is the vibration blowing mode or the specified direction blowing mode, the blowing direction of the first air outlet 24 can realize an oscillation change, or realize upward blowing in a specified direction and downward blowing in a specified direction, thereby changing the organizational mode of the indoor airflow, creating a changing indoor wind field and blowing feeling, improving the mixing efficiency of the indoor air wind, and reducing the blowing temperature difference at the far end, that is, the temperature difference felt by the human body, while rapidly mixing the wind with a high temperature difference from the first air outlet 24 with the indoor air, thereby achieving the effects of efficient blowing and rapid temperature mixing of the air conditioner 1.

[0079] As shown in FIG. 13, step S3 includes steps S321 to S326.

[0080] Step S321: The control device 50 determines whether the absolute value of the difference between the temperature set by the user and the current room temperature is smaller than the fourth set temperature. If the absolute value of the difference between the temperature set by the user and the current room temperature is smaller than the fourth set temperature, it executes step S322; if the absolute value of the difference between the temperature set by the user and the current room temperature is not smaller than the fourth set temperature, it executes step S323.

[0081] Step S322: The control device 50 controls the blowing direction of the air conditioner 1 so that air is blown upward in a predetermined direction or downward in a predetermined direction, controls the blower 11 so that it operates at the fourth set rotation speed, and returns to step S321.

[0082] Step S323: The control device 50 determines whether the absolute value of the difference between the temperature set by the user and the current room temperature is smaller than the fifth set temperature. If the absolute value of the difference between the temperature set by the user and the current room temperature is smaller than the fifth set temperature, it executes step S324; if the absolute value of the difference between the temperature set by the user and the current room temperature is not smaller than the fifth set temperature, it executes step S325.

[0083] Step S324: The control device 50 controls the blower 11 to operate at the fifth set rotation speed for only the first set time, then controls the blowing direction of the air conditioner 1 to blow upward in a specified direction or blow downward in a specified direction, and continues to operate for only the second set time, after which it returns to step S321.

[0084] Step S325: The control device 50 determines whether the absolute value of the difference between the temperature set by the user and the current room temperature is smaller than the sixth set temperature, and if the absolute value of the difference between the temperature set by the user and the current room temperature is smaller than the sixth set temperature, executes step S326.

[0085] Step S326: The control device 50 controls the blower 11 to operate at the sixth set rotation speed for only the third set time, then controls the blowing direction of the air conditioner 1 to blow upward in a specified direction or blow downward in a specified direction, and continues to operate for only the fourth set time, after which it returns to step S321.

[0086] The fourth, fifth and sixth set temperatures are set according to debugging of the air conditioner 1, or are automatically matched according to the room size, number of people and area information set by the user. The fifth set temperature is higher than the fourth set temperature and lower than the sixth set temperature. The fourth, fifth and sixth set rotation speeds are set according to the user's custom size and stored in the air conditioner 1. The fifth set rotation speed is higher than the fourth set rotation speed and lower than the sixth set rotation speed. The first, second, third and fourth set times are matched according to the user's usage space, the range in which the absolute value of the difference between the temperature set by the user and the current indoor temperature is located, and the shift position of the blower 11.

[0087] The control method of the air conditioner 1 disclosed herein can realize the switching of the blowing mode of the first air outlet 24 between the vibration blowing mode and the predetermined direction blowing mode, realize the rapid mixing of the blowing temperature of the first air outlet 24 and the indoor temperature, change the inherent indoor airflow tissue form (i.e., the airflow flows steadily through a certain space, and realizes indoor circulation in a stable state), create a changing indoor wind field and blowing feeling, improve the mixing efficiency of the indoor air wind, reduce the blowing temperature difference at the far end, and achieve the effects of efficient air supply, rapid temperature adjustment, and comfortable constant temperature of the air conditioner 1.
