Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air conditioning cabinet, an air supply control method for the air conditioning cabinet, and an air conditioner having the air conditioning cabinet or executing the air supply control method for the air conditioning cabinet. Background Art

[0002] In order to improve the comfort of air supply, the existing air-conditioning cabinet is provided with an upper air outlet and a lower air outlet, an upper fan is provided at the upper air outlet, and a lower fan is provided at the lower air outlet, an air duct is connected between the upper air outlet and the lower air outlet, and a partition is provided in the air duct to divide the air duct into two upper and lower independent sub-air ducts. When the circumference of the partition at least partially abuts the inner wall of the air duct, the partition divides the air duct into two upper and lower independent sub-air ducts, and the upper fan and the lower fan respectively make the upper air outlet and the lower air outlet blow out cold air or hot air at the same time, thereby realizing the upper and lower simultaneous air outlet mode; when the circumference of the partition is not in contact with the inner wall of the air duct, the air duct is not divided, that is, there is only one air duct, and the upper air outlet mode or the lower air outlet mode can be selected by controlling the opening and closing of the upper air guide plate at the upper air outlet and the lower air guide plate at the lower air outlet.

[0003] However, the partitions of the existing air conditioner cabinets are fixed in the vertical direction in the air duct, and the partitions are driven by a motor to rotate to realize one of the upper and lower air outlet modes, the upper air outlet mode, and the lower air outlet mode. Since the partitions of the existing air conditioner cabinets are fixed in the vertical direction, when the upper and lower air outlet mode is running, a large air volume can only be achieved by increasing the speed of the upper fan or the lower fan. However, as the fan speed increases, abnormal noise and operating energy consumption also increase synchronously.

[0004] In addition, affected by factors such as indoor airflow, ventilation conditions, and temperature differences, the indoor air is unevenly distributed in the vertical direction. Since the partitions of existing air-conditioning cabinets are fixed in the vertical direction, when operating in the upper and lower air outlet modes, there is a significant difference in the air intake volume of the upper air outlet and the lower air outlet, which leads to a significant difference in the air supply volume between the upper air outlet and the lower air outlet, thereby affecting the air supply comfort, and then affecting the heat exchange efficiency, resulting in a poor user experience. Summary of the invention

[0005] The first object of the present invention is to provide an air conditioning cabinet that can reduce abnormal noise and operating energy consumption while increasing the air supply volume, thereby improving the air supply comfort and heat exchange efficiency, and further improving the user experience.

[0006] The second object of the present invention is to provide an air supply control method for the above-mentioned air conditioning cabinet.

[0007] A third object of the present invention is to provide an air conditioner having the above-mentioned air conditioning cabinet or executing the air supply control method of the above-mentioned air conditioning cabinet.

[0008] In order to achieve the first object of the present invention, the present invention provides an air conditioning cabinet, including an evaporator, an air duct, an upper air blade, a lower air blade and a partition structure, the air duct is provided with an upper air outlet, a lower air outlet and an air inlet, the upper air outlet is located above the lower air outlet in the vertical direction, the upper air blade is rotatably supported in the air duct and is arranged close to the upper air outlet, the lower air blade is rotatably supported in the air duct and is arranged close to the lower air outlet, the air inlet is located between the upper air blade and the lower air blade and extends in the vertical direction, the evaporator is arranged at the air inlet, and the air duct and the air inlet are connected. The opposite cavity is the air inlet cavity, and the partition structure includes a movable control mechanism, a movable frame, an air partition plate and a rotation control mechanism. The movable frame can be moved in the air inlet cavity in the vertical direction, and the outer circumferential surface of the movable frame abuts between the inner circumferential surfaces of the air inlet cavity to divide the air inlet cavity into an upper air cavity and a lower air cavity. The movable control mechanism can control the movement of the movable frame in the vertical direction, and the movable frame is provided with ventilation holes in the vertical direction. The air partition plate is rotatably supported on the movable frame, and the rotation control mechanism can control the rotation of the air partition plate to open or close the ventilation holes.

[0009] It can be seen from the above scheme that when the air-conditioning cabinet of the present invention is executing the upper air outlet mode, the moving control mechanism of the air-conditioning cabinet of the present invention controls the moving frame to move with the wind baffle plate to the first preset position in the vertical direction, and the rotating control mechanism controls the wind baffle plate to rotate to open the ventilation hole of the moving frame, then controls the upper air blades to rotate forward and controls the lower air blades to reverse. Along with the forward rotation of the upper air blades, the indoor air flows from the air inlet of the air duct and enters the air inlet cavity of the air duct after heat exchange in the evaporator. Along with the reversal of the lower air blades, the indoor air flow is sent from the lower air outlet of the air duct to the air inlet cavity of the air duct, and then mixed with the heat exchange airflow in the air inlet cavity, passes through the ventilation holes of the moving frame together, and is sent into the room from the upper air outlet of the air duct. On the one hand, the air supply volume of the upper air outlet can be increased without increasing the rotation speed of the upper and lower air blades, thereby improving the heat exchange efficiency and reducing abnormal noise and operating energy consumption. On the other hand, the air supply hardness of the upper air outlet can be reduced, thereby improving the user experience comfort.

[0010] When the air-conditioning cabinet of the present invention is executing the down-air outlet mode, the moving control mechanism of the air-conditioning cabinet of the present invention controls the moving frame to move with the wind baffle plate to the second preset position in the vertical direction, and the rotating control mechanism controls the wind baffle plate to rotate to open the ventilation hole of the moving frame, then controls the upper wind blade to reverse and controls the lower wind blade to rotate forward, along with the forward rotation of the lower wind blade, the indoor air flows from the air inlet of the air duct and enters the air inlet cavity of the air duct after heat exchange through the evaporator, and along with the reversal of the upper wind blade, the indoor air flows from the upper air outlet of the air duct to the air inlet cavity of the air duct, and then mixes with the heat exchange airflow in the air inlet cavity, passes through the ventilation hole of the moving frame together, and is sent into the room from the lower air outlet of the air duct. On the one hand, without increasing the rotation speed of the upper wind blade and the lower wind blade, the air supply volume of the lower air outlet can be increased, the heat exchange efficiency is improved, and abnormal noise and operating energy consumption are reduced. On the other hand, the air supply hardness of the lower air outlet can be reduced, thereby improving the user experience and comfort.

[0011] When the air-conditioning cabinet of the present invention is executing the up and down air outlet mode, the moving control mechanism of the air-conditioning cabinet of the present invention controls the moving frame to move with the wind baffle plate to the third preset position in the vertical direction, and the rotating control mechanism controls the wind baffle plate to rotate to close the ventilation hole of the moving frame, thereby dividing the air inlet chamber of the air duct into an upper air chamber and a lower air chamber, and then controls the upper air blades to rotate forward and controls the lower air blades to rotate forward, and along with the forward rotation of the upper air blades, the indoor air flow enters the upper air chamber from the air inlet of the air duct after heat exchange in the evaporator, and then the heat exchange airflow in the upper air chamber is sent into the room from the upper air outlet of the air duct, and along with the forward rotation of the lower air blades, the indoor air flow enters the lower air chamber from the air inlet of the air duct after heat exchange in the evaporator, and then the heat exchange airflow in the lower air chamber is sent into the room from the lower air outlet of the air duct, thereby avoiding the mutual influence of the upper air outlet and the lower air outlet, thereby avoiding the wind competition phenomenon of the upper air outlet and the lower air outlet. When the air conditioner cabinet of the present invention executes the up and down air outlet mode, the position of the movable frame with the wind partition plate moved in the vertical direction can be controlled according to the air volume distribution ratio of the up and down air outlets, thereby correspondingly allocating the volume ratio of the upper air chamber and the lower air chamber according to the air volume distribution ratio of the up and down air outlets, so as to increase the air volume of the up and down air supply while reducing abnormal noise and operating energy consumption.

[0012] Therefore, when the air-conditioning cabinet of the present invention executes any working mode of the upper air outlet mode, the lower air outlet mode, or the upper and lower air outlet mode, it can increase the air supply volume while reducing abnormal noise and operating energy consumption, thereby improving the air supply comfort and heat exchange efficiency, and further improving the user experience.

The rotation control mechanism can control the wind baffle 152 to rotate to open or close the ventilation hole 1511.

[0042] When the air-conditioning cabinet 10 of the present embodiment is executing the upper air outlet mode, the movement control mechanism of the air-conditioning cabinet 10 of the present embodiment controls the moving frame 151 to move with the wind baffle 152 to a first preset position in the vertical direction, and the rotation control mechanism controls the wind baffle 152 to rotate to open the ventilation hole 1511 of the moving frame 151, then controls the upper wind blade 13 to rotate forward and controls the lower wind blade 14 to reverse, and with the forward rotation of the upper wind blade 13, the indoor air flow enters the air inlet cavity 114 of the air duct 11 from the air inlet 113 of the air duct 11 after heat exchange in the evaporator 12, and with the reverse rotation of the lower wind blade 14, the indoor air flow is sent from the lower air outlet 112 of the air duct 11 to the air inlet cavity 114 of the air duct 11, and then mixed with the heat exchange airflow in the air inlet cavity 114, passes through the ventilation hole 1511 of the moving frame 151 together and is sent into the room from the upper air outlet 111 of the air duct 11, as shown in FIG. Fig. 9 and Fig.11 As shown, on the one hand, the air supply volume of the upper air outlet 111 can be increased without increasing the rotation speed of the upper wind blades 13 and the lower wind blades 14, thereby improving the heat exchange efficiency and reducing abnormal noise and operating energy consumption. On the other hand, the air supply hardness of the upper air outlet 111 can be reduced, thereby improving the user experience comfort.

[0043] When the air conditioner cabinet 10 of this embodiment is executing the down-air outlet mode, the movement control mechanism of the air conditioner cabinet 10 of this embodiment controls the moving frame 151 to move with the wind baffle 152 to the second preset position in the vertical direction, and the rotation control mechanism controls the wind baffle 152 to rotate to open the ventilation hole 1511 of the moving frame 151, then controls the upper wind blade 13 to reverse and controls the lower wind blade 14 to rotate forward, and with the forward rotation of the lower wind blade 14, the indoor air flow enters the air inlet cavity 114 of the air duct 11 from the air inlet 113 of the air duct 11 after heat exchange in the evaporator 12, and with the reversal of the upper wind blade 13, the indoor air flow is sent from the upper air outlet 111 of the air duct 11 to the air inlet cavity 114 of the air duct 11, and then mixed with the heat exchange airflow in the air inlet cavity 114, passes through the ventilation hole 1511 of the moving frame 151 together and is sent into the room from the lower air outlet 112 of the air duct 11, as shown in FIG. Fig.10 and Fig.11 As shown, on the one hand, the air supply volume of the lower air outlet 112 can be increased without increasing the rotation speed of the upper wind blades 13 and the lower wind blades 14, thereby improving the heat exchange efficiency and reducing abnormal noise and operating energy consumption. On the other hand, the air supply hardness of the lower air outlet 112 can be reduced, thereby improving the user experience comfort.

[0044] When the air conditioner cabinet 10 of the present embodiment is in the upper and lower air outlet mode, the movement control mechanism of the air conditioner cabinet 10 of the present embodiment controls the moving frame 151 to move with the air baffle 152 to the third preset position in the vertical direction, and the rotation control mechanism controls the air baffle 152 to rotate to close the ventilation hole 1511 of the moving frame 151, thereby dividing the air inlet cavity 114 of the air duct 11 into the upper air cavity 1141 and the lower air cavity 1142, and then controls the upper air blade 13 to rotate forward and controls the lower air blade 14 to rotate forward, accompanied by The upper wind blade 13 rotates forward, and the indoor air flows from the air inlet 113 of the air duct 11 and enters the upper wind chamber 1141 after heat exchange in the evaporator 12. Then, the heat exchange airflow in the upper wind chamber 1141 is sent into the room from the upper air outlet 111 of the air duct 11. With the forward rotation of the lower wind blade 14, the indoor air flows from the air inlet 113 of the air duct 11 and enters the lower wind chamber 1142 after heat exchange in the evaporator 12. Then, the heat exchange airflow in the lower wind chamber 1142 is sent into the room from the lower air outlet 112 of the air duct 11. Fig.12 and Fig.13 As shown, the mutual influence between the upper and lower air outlets is avoided, thereby avoiding the phenomenon of the upper and lower air outlets competing for air. When the air conditioner cabinet 10 of this embodiment is executing the upper and lower air outlet mode, the position of the moving frame 151 with the air baffle 152 moved in the vertical direction can be controlled according to the air volume distribution ratio of the upper and lower air outlets, so as to correspondingly distribute the volume ratio of the upper air chamber 1141 and the lower air chamber 1142 according to the air volume distribution ratio of the upper and lower air outlets, so as to reduce abnormal noise and operating energy consumption while increasing the air volume of the upper and lower air supply.

[0045] Therefore, when the air-conditioning cabinet 10 of this embodiment executes any working mode of the upper air outlet mode, the lower air outlet mode, or the upper and lower air outlet mode, it can increase the air supply volume while reducing abnormal noise and operating energy consumption, thereby improving the air supply comfort and heat exchange efficiency, and further improving the user experience.

[0046] In order to improve the airtightness of the air baffle 152 closing the ventilation hole 1511, at least part of the outer peripheral surface of the air baffle 152 of this embodiment can abut against the inner peripheral surface of the ventilation hole 1511 to close the ventilation hole 1511. Specifically, a sealing member (not shown) is provided on the outer peripheral surface of the air baffle 152 of this embodiment, thereby further enhancing the airtightness of the air baffle 152 closing the ventilation hole 1511. Preferably, the sealing member of this embodiment is a sponge.

[0047] In order to improve the rotation control stability and reliability of the wind shield 152, the rotation control mechanism of this embodiment includes a rotating motor 154, a driving gear 155, a transmission chain 153 and a driven gear 156. The rotating motor 154 is arranged on the moving frame 151, and the driving gear 155 is sleeved on the driving shaft of the rotating motor 154. The two ends of the wind shield 152 are respectively provided with rotating shafts 1521, and the two rotating shafts 1521 are rotatably supported on the moving frame 151. The driven gear 156 is sleeved on one rotating shaft 1521, and the transmission chain 153 is sleeved between the driving gear 155 and the driven gear 156. Thus, as the driving shaft of the rotating motor 154 drives the driving gear 155 to rotate forward or reverse, the driving gear 155 synchronously drives the transmission chain 153 to move forward or reverse, so that the transmission chain 153 synchronously drives the driven gear 156 on the rotating shaft 1521 of the wind baffle 152 to rotate forward or reverse, thereby driving the wind baffle 152 to rotate forward or reverse to open or close the ventilation hole 1511, thereby ensuring that the rotation control of the wind baffle 152 is stable and reliable. Specifically, the number of wind baffles 152 in this embodiment is at least two, and the plurality of wind baffles 152 are arranged side by side at the ventilation hole 1511. A driven gear 156 is sleeved on a rotating shaft 1521 of one wind baffle 152, and the transmission chain 153 is sleeved between the driving gear 155 and the plurality of driven gears 156. The transmission chain 153 drives the plurality of driven gears 156 to rotate in the same phase, thereby achieving the same rotation angle of the plurality of wind baffles 152.

[0048] In order to improve the stability and reliability of the movement control of the moving frame 151, the movement control mechanism of this embodiment includes a moving motor 158, a guide rack 157 and a transmission gear (not shown), the guide rack 157 is arranged in the air inlet chamber 114 and extends in the vertical direction, the moving motor 158 is arranged on the moving frame 151, and the transmission gear is sleeved on the driving shaft of the moving motor 158 and meshes with the guide rack 157. Therefore, along with the driving shaft of the moving motor 158 driving the transmission gear to rotate forward or reverse, since the transmission gear and the guide rack 157 mesh with each other, the moving frame 151 arranged on the moving motor 158 is forced to move upward or downward in the vertical direction, so that the movement control of the moving frame 151 is stable and reliable. Specifically, the transmission gear of this embodiment is made of rubber material, thereby increasing the meshing friction between the transmission gear and the guide rack 157, so that the meshing of the transmission gear and the guide rack 157 is stable and reliable, and can self-lock and stabilize in a certain position, so that the movable frame 151 can move stably and reliably in the vertical direction and can self-lock and stabilize in a certain position to avoid slipping.

[0049] Specifically, in this embodiment, the upper wind blades 13 and the lower wind blades 14 are both axial flow blades. The upper wind blades 13 rotate in the vertical direction, and the upper air outlet 111 is located directly above the upper wind blades 13 in the vertical direction. The lower wind blades 14 rotate in the vertical direction, and the lower air outlet 112 is located below the lower wind blades 14 in the vertical direction and on the sides of the lower wind blades 14 in the horizontal direction.

[0050] In order to further reduce noise and optimize the sound quality effect, the upper wind blade 13 of this embodiment includes a first hub 131 and a plurality of first blades 132 arranged circumferentially on the outer peripheral wall of the first hub 131, each of the first blades 132 is provided with a plurality of first serrated grooves 133 on the first trailing edge in the radial direction of the first hub 131, the plurality of first serrated grooves 133 are arranged along the extension direction of the first trailing edge, and the suction surface of each first blade 132 is concavely provided with a plurality of first grooves 134, and the lower wind blade 14 of this embodiment includes a second hub 141 and a plurality of second blades 142 arranged circumferentially on the outer peripheral wall of the second hub 141, each of the second blades 142 is provided with a plurality of second serrated grooves 143 on the second trailing edge in the radial direction of the second hub 141, the plurality of second serrated grooves 143 are arranged along the extension direction of the second trailing edge, and the suction surface of each second blade 142 is concavely provided with a plurality of second grooves 144.

[0051] Furthermore, when the air-conditioning cabinet 10 of the present embodiment executes the upper air outlet mode or the lower air outlet mode, the rotation control mechanism controls the air baffle plate 152 to rotate to a vertical state to open the ventilation holes 1511 of the movable frame 151, so that the flow area of ​​the airflow through the ventilation holes 1511 of the movable frame 151 is maximized, and the resistance of the air baffle plate 152 to the airflow is minimized; when the air-conditioning cabinet 10 of the present embodiment executes the upper and lower air outlet mode, the rotation control mechanism controls the air baffle plate 152 to rotate to a horizontal state to close the ventilation holes 1511 of the movable frame 151, so as to separate the air inlet cavity 114 of the air duct 11 into an upper air cavity 1141 and a lower air cavity 1142, so as to avoid mutual influence between the upper air outlet and the lower air outlet, thereby avoiding the phenomenon of wind competition between the upper air outlet and the lower air outlet.

[0053] The air supply control method of the air conditioning cabinet in this embodiment is the air supply control method of the air conditioning cabinet 10 embodiment described above, and the air supply control method includes: an upper air outlet mode, a lower air outlet mode, and an upper and lower air outlet mode.

[0054] The upper air outlet mode includes: the moving control mechanism controls the moving frame 151 to move to a first preset position in the vertical direction, the rotating control mechanism controls the wind baffle 152 to rotate to open the ventilation hole 1511, the upper wind blades 13 rotate forward to deliver the airflow in the air inlet cavity 114 from the upper air outlet 111 to the indoor room, and the lower wind blades 14 reverse to deliver the indoor airflow from the lower air outlet 112 to the air inlet cavity 114. Thus, when the air-conditioning cabinet 10 of this embodiment is executing the upper air outlet mode, the movement control mechanism of the air-conditioning cabinet 10 of this embodiment controls the moving frame 151 to move with the wind baffle 152 to a first preset position in the vertical direction, and the rotation control mechanism controls the wind baffle 152 to rotate to open the ventilation hole 1511 of the moving frame 151, then controls the upper fan blade 13 to rotate forward and controls the lower fan blade 14 to reverse. With the forward rotation of the upper fan blade 13, the indoor air flows from the air inlet 113 of the air duct 11 and enters the air inlet cavity 114 of the air duct 11 after heat exchange in the evaporator 12. With the reverse rotation of the lower fan blade 14, the indoor air flows from the lower air outlet 112 of the air duct 11 to the air inlet cavity 114 of the air duct 11, and then mixes with the heat exchange airflow in the air inlet cavity 114, passes through the ventilation hole 1511 of the moving frame 151 together, and is sent into the room from the upper air outlet 111 of the air duct 11. Fig. 9 and Fig.11 As shown, on the one hand, the air supply volume of the upper air outlet 111 can be increased without increasing the rotation speed of the upper wind blades 13 and the lower wind blades 14, thereby improving the heat exchange efficiency and reducing abnormal noise and operating energy consumption. On the other hand, the air supply hardness of the upper air outlet 111 can be reduced, thereby improving the user experience comfort.

[0055] The lower air outlet mode includes: the moving control mechanism controls the moving frame 151 to move to a second preset position in the vertical direction, the rotating control mechanism controls the wind baffle 152 to rotate to open the ventilation hole 1511, the lower wind blades 14 rotate forward to send the airflow in the air inlet cavity 114 from the lower air outlet 112 to the indoor room, and the upper wind blades 13 reverse to send the indoor airflow from the upper air outlet 111 to the air inlet cavity 114. Thus, when the air-conditioning cabinet 10 of this embodiment is executing the down-air outlet mode, the movement control mechanism of the air-conditioning cabinet 10 of this embodiment controls the moving frame 151 to move with the wind baffle 152 to the second preset position in the vertical direction, and the rotation control mechanism controls the wind baffle 152 to rotate to open the ventilation hole 1511 of the moving frame 151, then controls the upper wind blade 13 to reverse and controls the lower wind blade 14 to rotate forward, and with the forward rotation of the lower wind blade 14, the indoor air flows from the air inlet 113 of the air duct 11 and enters the air inlet cavity 114 of the air duct 11 after heat exchange through the evaporator 12, and with the reversal of the upper wind blade 13, the indoor air flows from the upper air outlet 111 of the air duct 11 to the air inlet cavity 114 of the air duct 11, and then mixes with the heat exchange airflow in the air inlet cavity 114, passes through the ventilation hole 1511 of the moving frame 151 together, and is sent into the room from the lower air outlet 112 of the air duct 11, as shown in FIG. Fig.10 and Fig.11 As shown, on the one hand, the air supply volume of the lower air outlet 112 can be increased without increasing the rotation speed of the upper wind blades 13 and the lower wind blades 14, thereby improving the heat exchange efficiency and reducing abnormal noise and operating energy consumption. On the other hand, the air supply hardness of the lower air outlet 112 can be reduced, thereby improving the user experience comfort.

[0056] The up-and-down air outlet mode includes: the movement control mechanism controls the movement frame 151 to move to the third preset position in the vertical direction, the rotation control mechanism controls the wind baffle plate 152 to rotate to close the ventilation hole 1511, the upper wind blade 13 rotates forward to send the upper air cavity 1141 airflow from the upper air outlet 111 to the room, and the lower wind blade 14 rotates forward to send the lower air cavity 1142 airflow from the lower air outlet 112 to the room. Thus, when the air conditioner cabinet 10 of this embodiment executes the up-and-down air outlet mode, the movement control mechanism of the air conditioner cabinet 10 of this embodiment controls the movement frame 151 to move to the third preset position in the vertical direction with the wind baffle plate 152, and the rotation control mechanism controls the wind baffle plate 152 to rotate to close the ventilation hole 1511 of the movement frame 151, thereby dividing the air inlet cavity 114 of the air duct 11 into the upper air cavity 1141 and the lower air cavity 1142, then the upper wind blade 13 is controlled to rotate forward and the lower wind blade 14 is controlled to rotate forward, accompanied by As the upper fan blades 13 rotate forward, the indoor air flows from the air inlet 113 of the air duct 11 and enters the upper air chamber 1141 after heat exchange in the evaporator 12, and then the heat exchange air flow in the upper air chamber 1141 is sent into the room from the upper air outlet 111 of the air duct 11, and as the lower fan blades 14 rotate forward, the indoor air flows from the air inlet 113 of the air duct 11 and enters the lower air chamber 1142 after heat exchange in the evaporator 12, and then the heat exchange air flow in the lower air chamber 1142 is sent into the room from the lower air outlet 112 of the air duct 11, as shown in FIG. Fig.12 and Fig.13 As shown, the mutual influence between the upper and lower air outlets is avoided, thereby avoiding the phenomenon of the upper and lower air outlets competing for air. When the air conditioner cabinet 10 of this embodiment is executing the upper and lower air outlet mode, the position of the moving frame 151 with the air baffle 152 moved in the vertical direction can be controlled according to the air volume distribution ratio of the upper and lower air outlets, so as to correspondingly distribute the volume ratio of the upper air chamber 1141 and the lower air chamber 1142 according to the air volume distribution ratio of the upper and lower air outlets, so as to reduce abnormal noise and operating energy consumption while increasing the air volume of the upper and lower air supply.

[0057] Specifically, the height of the air inlet 113 of the air duct 11 in the vertical direction is H, and the distance between the moving frame 151 and the lower end of the air inlet 113 in the vertical direction is A. When the air conditioning cabinet 10 is controlled to perform the upper air outlet mode, the moving control mechanism controls the moving frame 151 to move to the first preset position in the vertical direction, at which time the distance between the moving frame 151 and the lower end of the air inlet 113 in the vertical direction is A=0.5×H, that is, the moving frame 151 moves to the middle of the air inlet 113 of the air duct 11 in the vertical direction. When the air conditioning cabinet 10 is controlled to perform the lower air outlet mode, the moving control mechanism controls the moving frame 151 to move to the second preset position in the vertical direction, at which time the distance between the moving frame 151 and the lower end of the air inlet 113 in the vertical direction is A=0.5×H. When the air-conditioning cabinet 10 is controlled to execute the upper and lower air outlet mode, the mobile control mechanism controls the moving frame 151 to move to the third preset position in the vertical direction. At this time, the distance A between the moving frame 151 and the lower end of the air inlet 113 in the vertical direction is A=α×H, and the α is the proportional coefficient between the preset air volume of the lower air outlet 112 and the preset total air volume of the air-conditioning cabinet 10. Therefore, according to the air volume distribution ratio of the upper and lower air outlets, the moving frame 151 is controlled to move with the wind baffle plate 152 in the vertical direction to the corresponding third preset position, that is, the volume ratio of the upper air cavity 1141 and the lower air cavity 1142 is correspondingly distributed according to the air volume distribution ratio of the upper and lower air outlets, so as to increase the air volume of the upper and lower air supply while reducing abnormal noise and operating energy consumption.

[0058] Furthermore, in this embodiment, α is a proportional coefficient between 0.53 and 0.63. Preferably, in this embodiment, α is a proportional coefficient of 0.6. When the air conditioner cabinet 10 is controlled to perform the up and down air outlet mode, the mobile control mechanism controls the mobile frame 151 to move with the wind baffle 152 to the third preset position in the vertical direction, that is, the distance A between the mobile frame 151 and the lower end of the air inlet 113 in the vertical direction is A=0.6×H, and the forward rotation speed of the upper wind blade 13 is the same as the forward rotation speed of the lower wind blade 14. Fig.14 From the air volume fluctuation simulation diagram when the air-conditioning cabinet 10 of the present embodiment executes the up and down air outlet mode, it can be seen that, relative to the existing air-conditioning cabinet with fixed partitions, the standard deviation of the total air volume of the up and down air outlet of the air-conditioning cabinet 10 of the present embodiment is significantly reduced, and the reduction range of the total air volume standard deviation is 25%, and the amplitude of the air volume fluctuation is also significantly reduced, and the reduction range of the amplitude of the air volume fluctuation is 40%. While increasing the air volume of the up and down air supply, it greatly reduces abnormal noise and operating energy consumption. The sound quality of the up and down air supply of the air-conditioning cabinet 10 of the present embodiment is effectively improved.
