Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, and in particular to a partitioned air control device, a control method thereof, and an air conditioner. BACKGROUND

[0002] Wall-mounted, ducted, and cabinet air conditioners of various types generally control air in a single direction, i.e., air is blown in one direction at a time, which results in some areas not participating in air circulation, and thus the temperature distribution in the room is uneven. For example, a person below the air outlet of the air conditioner often feels hot, while a person directly opposite the air conditioner often feels cold. To solve this problem, an up-and-down air sweeping method is often used. This method is simple, but because the air blowing direction of the air conditioner is limited by the structure, i.e., the air blowing angle is limited, the air flow below the air conditioner cannot participate in circulation, and the temperature difference problem cannot be solved.

[0003] To solve the problem of different area requirements, a double air system is designed, which can independently control the air blowing of two areas. However, this system is costly, requiring two large motors, fan blades, temperature control systems, and air guide systems. This system is costly and has a more complex structure.

[0004] In the prior art, a wind guide plate is divided into two parts to control the air flow on the left and right sides, respectively. However, this method often requires multiple control systems to independently control multiple wind guide plates. Although the execution structure is simple, the increase in control components also leads to an increase in cost, complex control logic, and other problems. SUMMARY

[0005] A first object of the present application is to provide a partitioned air control device that can control air in different areas through a simple structure.

[0006] A second object of the present application is to provide a control method for the partitioned air control device described above.

[0007] A third object of the present application is to provide another control method for the partitioned air control device described above.

[0008] A fourth object of the present application is to provide an air conditioner that uses the partitioned air control device described above.

[0009] To achieve the above first object, the application provides a partitioned air control device, comprising: an air outlet shell, the air outlet shell having a shell front wall and a shell bottom wall arranged in intersection, the shell front wall being provided with a first upper air outlet, and the shell bottom wall being provided with a first lower air outlet; a first air control plate, the first air control plate being in sliding cooperation with the air outlet shell; an air control plate driving mechanism, the air control plate driving mechanism being capable of driving the first air control plate to move between a first position and a second position; in the first position, the first air control plate closes the first upper air outlet and opens the first lower air outlet; in the second position, the first air control plate closes the first lower air outlet and opens the first upper air outlet.

[0010] As can be seen from the above scheme, by arranging the air outlets on the bottom wall and the side wall of the shell respectively, the air supply towards the front side or the air supply towards the lower side can be realized by driving the first air control plate to move by the air control plate driving mechanism, and then the air control of different areas is realized, thereby solving the problems of uneven indoor temperature distribution, high cost of double air system, and slow heat exchange caused by single air supply circulation. Moreover, the partitioned air control device is adapted on the basis of the existing model, and the partitioned air control device is added to realize the air control without greatly changing the existing model, thereby avoiding the disadvantages of developing a new model for a new function, and greatly reducing the development cost of new products.

[0011] A preferred scheme is that the inner side surface of the first air control plate is provided with a first driving guide rail, the first driving guide rail extending along the diagonal line of the first air control plate; the air control plate driving mechanism comprises a first slider assembly and a slider driving assembly, the first slider assembly being in sliding cooperation with the first driving guide rail, and the slider driving assembly driving the first slider assembly to move, the first slider assembly driving the first air control plate to slide relative to the air outlet shell between the first position and the second position.

[0012] A further scheme is that the slider driving assembly comprises a driving member, a driving wheel, a first driven wheel, a first transmission member, a first guide wheel and a first traction member; the first slider assembly comprises a first slider body and a first rotating ring, the first rotating ring being arranged on the first slider body and being capable of rotating relative to the first slider body; the first transmission member is sleeved on the first driven wheel and the first guide wheel, the first slider assembly being located in the first transmission member, the first traction member being made of flexible material, and two ends of the first traction member being connected with the first rotating ring and the first transmission member respectively; the driving member drives the driving wheel to rotate in the forward direction, the driving wheel drives the first driven wheel to rotate, the first driven wheel drives the first transmission member to rotate around the first driven wheel and the first guide wheel, and the first transmission member drives the first slider assembly to move.

[0013] Therefore, through the setting of the first traction member, the first conveying member is connected with the first slider assembly, and in the movement process of the first conveying member, the first slider assembly is driven to move forward, and meanwhile, due to the setting of the first rotating ring, when the first slider assembly reaches the end of the track, the flexible first traction member can drive the first rotating ring to rotate relatively without winding, and since the first traction member is arranged at the bottom of the first conveying member and is not blocked by any structure at the bottom, the first traction member can smoothly realize turning and reversing, so that the first slider assembly can reciprocate.

[0014] Further, the second upper air outlet is arranged on the front wall of the shell, and the second lower air outlet is arranged on the bottom wall of the shell, the first upper air outlet and the second upper air outlet are arranged along the length direction of the air outlet shell, the first lower air outlet and the second lower air outlet are arranged along the length direction of the air outlet shell, the first upper air outlet and the first lower air outlet are arranged correspondingly, and the second upper air outlet and the second lower air outlet are arranged correspondingly; the zoning air control device further comprises a second air control plate, the second air control plate is arranged along the length direction of the air outlet shell and is in sliding fit with the air outlet shell, and the air control plate driving mechanism can drive the second air control plate to move between the third position and the fourth position; in the third position, the second air control plate closes the second upper air outlet and opens the second lower air outlet; and in the fourth position, the second air control plate closes the second lower air outlet and opens the second upper air outlet.

[0015] Therefore, the device has two air control plates, can adjust the air supply of four air control areas, and can realize four air supply modes of left lower, right upper, left upper, right lower, left upper and right upper, and left lower and right lower, the air control plates are of arc type, can switch positions along the track, the principle is simple, and the air volume is not affected. Meanwhile, by dividing the air outlet into four areas, the two air control plates can move in the corresponding two areas, thereby realizing air control of different areas, and since the temperature of the indoor air retention area can only be exchanged by natural diffusion of temperature, the speed is slow, the more the space participating in air circulation, the less the air retention area, and the faster the indoor heat exchange speed, so that the four air control areas can realize multiple air circulation, make the indoor temperature more balanced, and realize rapid heat exchange.

[0016] Further, the inner side surface of the second air control plate is provided with a second driving guide rail extending along the diagonal line of the second air control plate; the air control plate driving mechanism further comprises a second slider assembly in sliding fit with the second driving guide rail, the slider driving assembly drives the second slider assembly to move, and the second slider assembly drives the second air control plate to slide relative to the air outlet shell between the third position and the fourth position.

[0017] Further, the slider driving assembly further comprises a second driven wheel, a second transmission member, a second guide wheel and a second traction member; the second slider assembly comprises a second slider body and a second rotating ring arranged on the second slider body and rotatable relative to the second slider body; the second transmission member is sleeved on the second driven wheel and the second guide wheel, and the second slider assembly is located in the second transmission member; the second traction member is made of flexible material, and two ends of the second traction member are connected with the second rotating ring and the second transmission member respectively; the driving member drives the driving wheel to rotate reversely, the driving wheel drives the second driven wheel to rotate, the second driven wheel drives the second transmission member to rotate around the second driven wheel and the second guide wheel, and the second transmission member drives the second slider assembly to move.

[0018] Therefore, the air flow control over different areas is realized by controlling two air control plates by a single motor, which is low in cost and high in efficiency. Meanwhile, the second transmission member is connected with the second slider assembly by the second traction member, the second slider assembly is driven to move forward by the second transmission member during movement, and the flexible second traction member can drive the second rotating ring to rotate relatively without winding when the second slider assembly reaches the end of the track, and the second traction member can smoothly realize turning and reversing, so that the second slider assembly can move reciprocally.

[0019] Further, the first transmission member is a transmission belt or a transmission chain; and / or the second transmission member is a transmission belt or a transmission chain; and / or at least one of the first traction member and the second traction member is a rope.

[0020] Preferably, the first driven wheel and the second driven wheel each comprise a unidirectional gear and a transmission gear arranged coaxially, the unidirectional gear is in transmission connection with the driving wheel, and the transmission gear is in transmission connection with the corresponding transmission member; the driving member can only drive the unidirectional gear of the first driven wheel to rotate in a first direction, and can only drive the unidirectional gear of the second driven wheel to rotate in a second direction, the first direction being opposite to the second direction.

[0021] Therefore, two air control plates are controlled by a single motor, and the movements of the air control plates are independent of each other and do not affect each other, the motor controls the left and right air control plates by controlling the unidirectional gears, different directions of the motor can control different air control plates, thereby realizing independent control of the double air guide plates by a single motor, which saves cost and space.

[0022] When the driving member rotates forward, the one-way gear of the first driven wheel rotates in the first direction, and the inner rotating part of the second driven wheel does not rotate, so the second transmission member and the second slider assembly are not moved, the driving member can only drive the first slider assembly to move, and the position of the first air control plate is controlled. When the driving member reverses, the one-way gear of the second driven wheel rotates in the second direction, and the inner rotating part of the first driven wheel does not rotate, so the first transmission member and the first slider assembly are not moved, the driving member can only drive the second slider assembly to move, and the position of the second air control plate is controlled. The zoned air control device can only use one stepper motor as the driving member, and can independently control two sets of motion systems by forward and reverse rotation, so as to control four areas respectively and meet the air supply demand of different areas.

[0023] Further, the one-way gear comprises an inner rotating part and an outer rotating part arranged in the radial direction, the outer rotating part can only rotate in one direction relative to the inner rotating part, the transmission gear is coaxially arranged and fixedly connected with the inner rotating part, and the outer rotating part is in transmission connection with the driving wheel; the one-way gear further comprises a ratchet, the ratchet is located between the inner rotating part and the outer rotating part, the inner circumferential wall of the outer rotating part is provided with a plurality of teeth arranged in the circumferential direction, the first end of the ratchet is hinged to the inner rotating part, and the second end of the ratchet is in abutment with the teeth, so that the outer rotating part can only rotate in one direction relative to the inner rotating part.

[0024] Preferably, the first slider body and the second slider body each comprise a first limiting block, a supporting column, a second limiting block and a sliding column connected in sequence in the axial direction of the driving wheel; the first rotating ring is sleeved on the supporting column of the first slider body, and the second rotating ring is sleeved on the supporting column of the second slider body; the sliding column of the first slider body is in sliding fit with the first driving guide rail, and the sliding column of the second slider body is in sliding fit with the second driving guide rail; in the axial direction of the driving wheel, the first transmission member is located between the first limiting block of the first slider body and the second limiting block of the first slider body, and the second transmission member is located between the first limiting block of the second slider body and the second limiting block of the second slider body.

[0025] Therefore, through the arrangement of the first limiting block and the second limiting block, the sliding direction of the slider assembly is limited, through the arrangement of the supporting column, the installation and positioning of the rotating ring are facilitated, and through the arrangement of the sliding column, the sliding fit of the slider body and the driving guide rail is facilitated, and the smoothness of sliding is ensured. In order to further improve the smoothness of the two sliding fits, the bottom end of the sliding column can be provided in a spherical cap shape or other convex arc surface.

[0027] Therefore, by the first slider assembly and the second slider assembly being in sliding fit with the containing cavity, the sliding direction of the first slider body and the second slider body is limited, so that linear motion is ensured, and the corresponding air control plate is pushed to move.

[0028] A further scheme is that the fixed support is further provided with a first baffle, a second baffle, a third baffle and a fourth baffle; the first baffle is arranged close to the first driven wheel and on the side of the first driven wheel away from the driving wheel, the second baffle is arranged close to the first guide wheel and on the side of the first guide wheel close to the driving wheel, the first baffle and the second baffle limit the displacement of the first slider assembly in the length direction of the containing cavity; the third baffle is arranged close to the second driven wheel and on the side of the second driven wheel away from the driving wheel, the fourth baffle is arranged close to the second guide wheel and on the side of the second guide wheel close to the driving wheel, the third baffle and the fourth baffle limit the displacement of the second slider assembly in the length direction of the containing cavity.

[0029] Therefore, a baffle is arranged at the end of the slider assembly, and the baffle is fixedly connected with the fixed support of the air control device, which limits the movement of the slider and protects other structures, so that interference between the slider and other parts such as the rotating wheel is avoided.

[0030] A further scheme is that the first baffle, the second baffle, the third baffle and the fourth baffle all extend along the axial direction of the driving wheel and are all arc-shaped; the first baffle is curved away from the first driven wheel, the second baffle is curved away from the first guide wheel, the third baffle is curved away from the second driven wheel, and the fourth baffle is curved away from the second guide wheel.

[0031] Therefore, by designing the baffles to be arc-shaped, the shape of the baffles can be matched with that of the corresponding driven wheel or guide wheel, so that the protection of the components is realized, and the space can be reasonably utilized to reduce the occupied area.

[0032] A preferred scheme is that the first end of the first traction member is connected to the first side wall of the first conveying member, the first side wall is close to the first driving guide rail in the axial direction of the driving wheel, and the two ends of the first traction member are arranged close to each other in the axial direction of the driving wheel; and / or the first end of the second traction member is connected to the second side wall of the second conveying member, the second side wall is close to the second driving guide rail in the axial direction of the driving wheel, and the two ends of the second traction member are arranged close to each other in the axial direction of the driving wheel.

[0034] Therefore, through the arrangement of more than four air control areas, the circulation of more air currents can be realized, and the indoor temperature is more regionally balanced.
