Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air sweeping structure and an air conditioner. Background Art

[0002] The sweeping blades of a vertical air conditioner usually only have the function of sweeping air left and right, and the left and right sweeping air function is achieved by swinging the sweeping blades left and right. The vertical air conditioner in the prior art does not have the up and down sweeping air function, and cannot bring a better experience to the user.

[0003] Based on this, the applicant proposed an air sweeping structure and an air conditioner to solve the above technical problems. Summary of the invention

[0004] The problem solved by the present invention is that the prior art has no upward and downward sweeping function.

[0005] To solve the above problems, the present invention provides an air sweeping structure, comprising: an outer shell; a plurality of air sweeping blades arranged in parallel, the air sweeping blades being movably connected to the outer shell, and the air sweeping blades can swing left and right relative to the outer shell; a driving structure, the driving structure can drive the plurality of air sweeping blades to swing left and right; the air sweeping blades also include: a plurality of baffles, the plurality of baffles are arranged along the up and down directions, and the baffles are inclined; when the driving structure drives the air sweeping blades to rotate, the air outlet direction is changed up and down under the action of the baffles.

[0006] Compared with the prior art, the technical effect that can be achieved by adopting the present scheme is as follows: a plurality of wind sweeping blades can swing left and right relative to the outer shell, and a driving structure is adopted to drive the plurality of wind sweeping blades to swing left and right, and a plurality of baffles are arranged in the wind sweeping blades, and the plurality of baffles can be arranged along the up and down directions, and the baffles are arranged at an angle. Since the inclination angle of the baffle is fixed, when the wind sweeping blades rotate left and right, the baffles rotate a certain angle with the wind sweeping blades to change the air outlet direction of the baffles, and the function of sweeping air up and down can be realized by rotating the wind sweeping blades left and right.

[0007] In this embodiment, the wind sweeping blade further comprises: a frame body, which is hollowed out in the front-to-back direction; and the baffle is installed on the inner side wall of the frame body at a fixed tilt angle.

[0008] The technical effect after adopting this technical solution is that the frame is hollowed out in the front and rear directions to serve as the overall frame of the wind sweeping blades, and the baffle is installed on the inner wall of the frame at a fixed tilt angle so that the baffle inside the frame is tilted at an angle to achieve up and down blowing.

[0009] In this embodiment, in an initial state, the baffle is inclined upward at a fixed angle; when the wind sweeping blade rotates in the left-right direction by a first angle, the baffle is inclined downward at a fixed angle.

[0010] The technical effect after adopting this technical solution is that since the wind sweeping blade rotates around the rotating axis as a whole, and the center line of the baffle is also on the rotating axis, that is, when the baffle rotates with the rotating axis, the air outlet direction of the baffle can be tilted upward or downward according to the rotation angle of the rotating axis.

[0011] In this embodiment, the driving structure includes: a gear box shell, which includes a gear set, and the gear set includes a plurality of first gears and a plurality of transmission gears, each transmission gear is meshed between two of the first gears; a motor, and the output shaft of the motor is connected to one of the first gears; and a plurality of the wind sweeping blades are connected to the plurality of the first gears in a one-to-one corresponding manner.

[0012] The technical effect after adopting this technical solution is that the driving structure includes a gear set, and one of the first gears in the gear set is driven to rotate by a motor. The first gear and the wind sweeping blade are coaxially connected, that is, the wind sweeping blade is driven to rotate by the rotation of the first gear. The two adjacent first gears are meshed through a transmission gear to ensure that the rotation directions of all the first gears are consistent. The corresponding multiple first gears correspond to multiple wind sweeping blades, so as to achieve the purpose of synchronous rotation of multiple wind sweeping blades.

[0013] In this embodiment, the transmission gear and the first gear are of the same size, ensuring that when the motor drives the first gear to rotate, the meshing action of the transmission gear and the first gear makes the left and right swing angles of the plurality of wind sweeping blades consistent.

[0014] The technical effect after adopting this technical solution is that in order to ensure that the rotation angles of multiple wind-sweeping blades are consistent, the sizes of the transmission gear and the first gear are consistent, which ensures the transmission ratio of the transmission gear and the second gear, and utilizes the left and right swinging of the vertical air conditioner to discharge air.

[0015] In this embodiment, a limiting structure for limiting the left and right rotation angle of the wind sweeping blade is also included, and the limiting structure includes: a first engaging member fixedly connected to the gear box housing; a second engaging member arranged on the transmission gear or the first gear; when the driving structure drives the wind sweeping blade to rotate left and right and is about to exceed a preset rotation angle range, the second engaging member abuts against the first engaging member to limit the driving structure from continuing to drive the wind sweeping blade to rotate.

[0016] The technical effect of adopting this technical solution is that the first engaging member and the second engaging member cooperate to limit the maximum angle range of the left and right swing of the sweeping blade driven by the driving structure. When the rotation angle of the sweeping blade is about to exceed the preset rotation angle, the first engaging member and the second engaging member conflict to limit the driving structure from continuing to operate, thereby limiting the rotation of the sweeping blade, thus avoiding the phenomenon that the sweeping blade swings excessively left and right when the sensor fails when the motor controls the preset angle.

[0017] In this embodiment, the second engaging member protrudes along the circular surface of the first gear or the transmission gear, and the first engaging member protrudes along the inner side of the top wall of the gear box shell. When the left and right rotation angle of the wind sweeping blade is about to exceed a preset range, the first engaging member and the second engaging member cooperate to limit the left and right rotation angle of the wind sweeping blade.

[0018] The technical effect after adopting this technical solution is that by setting a second engaging member protruding from the end face, after the first gear or the transmission gear rotates to a certain preset angle, the first engaging member and the second engaging member interfere with each other, thereby limiting the continued rotation of the first gear or the transmission gear, and ultimately limiting the left and right rotation angles of the wind sweeping blades.

[0019] In this embodiment, the first engaging member includes a first limit stop rib and a second limit stop rib protruding along the inner side of the top wall of the gear box shell; in an initial state, the second engaging member is in contact with the first limit stop rib, and when the wind sweeping blade is at the maximum rotation angle, the second engaging member is in contact with the second limit stop rib; there is an arc transition between the first limit stop rib and the second limit stop rib.

[0020] The technical effect after adopting this technical solution is that the first engaging member more specifically adopts the first limiting rib and the second limiting rib. According to the setting positions of the first limiting rib and the second limiting rib, the rotation angle of the second engaging member can be limited to achieve the limiting effect.

[0021] In this embodiment, the wind sweeping blade further includes: a rotating sleeve, which is arranged at one end of the frame body close to the gear box shell; the rotating sleeve cooperates with the transmission shaft where the first gear is located, so that the first gear drives the frame body to rotate left and right.

[0022] The technical effect after adopting this technical solution is that, in order to ensure that the rotation of the first gear can stably drive the wind sweeping blade to rotate, the wind sweeping blade in the prior art is improved, the wind sweeping blade main body is a frame, and the air outlet direction adopts a hollow design, in which multiple baffles are arranged; and a rotating sleeve is provided at one end of the frame close to the gear box, and a hole for inserting the transmission shaft is provided in the rotating sleeve, and the rotating sleeve is matched with the key-like function to achieve stable transmission.

[0023] In this embodiment, an air conditioner includes: the wind sweeping structure described above, and a groove for installing the wind sweeping structure is provided in the shell. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] The present invention provides a wind sweeping structure, such as Figure 1-7 As shown, it includes: a shell 100; a plurality of wind sweeping blades 110 arranged in parallel, the wind sweeping blades 110 are movably connected to the shell 100, and the wind sweeping blades 110 can swing left and right relative to the shell 100; a driving structure 120, and the driving structure 120 can drive the plurality of wind sweeping blades 110 to swing left and right; the wind sweeping blades 110 also include: a plurality of baffles 500, the plurality of baffles 500 are arranged along the up and down directions, and the baffles 500 are inclined; when the driving structure 120 drives the wind sweeping blades 110 to rotate, the up and down air outlet directions are changed under the action of the baffles 500.

[0034] The housing 100 is a housing 100 of a conventional neutral air conditioner, such as Figure 1 The sweeping blades 110 are movably connected to the housing 100 in parallel from left to right, so that the sweeping blades 110 can swing left and right relative to the housing 100, and the distance between adjacent sweeping blades 110 is kept consistent to ensure that the sweeping blades 110 can achieve a uniform air outlet when they swing left and right to sweep the air.

[0035] The driving structure 120 can simultaneously drive the wind sweeping blades 110 to swing left and right relative to the housing 100. The driving structure 120 can use a motor 800 to drive a gear rack and other structures, and by setting a gear on the axis of each wind sweeping blade 110, the motor 800 drives multiple gears to rotate synchronously to achieve the purpose of simultaneous rotation of multiple wind sweeping blades 110, or a gear set is used, in which a transmission gear 310 and a first gear 300 are provided, and the first gear 300 is coaxially arranged on the wind sweeping blade 110, and a transmission gear 310 is provided between two adjacent first gears 300 to achieve a transmission effect.

[0036] like Figure 3-6 The wind sweeping blade 110 adopts a frame 610. In order to maintain a reasonable and certain amount of wind outflow in the air outlet direction, the frame 610 adopts a hollow design. A plurality of baffles 500 are arranged along the first direction of the frame 610. The length of each baffle 500 can be the same or different. Baffles 500 of the same length can keep the air volume consistent, and baffles 500 of different lengths can be used according to actual needs. For example, when a larger air volume is required in the middle, the length of the baffle 500 can be set to be shorter to increase the air volume; if a smaller air volume is required at the bottom, the length of the baffle 500 can be set to be longer.

[0037] As a further optimization, the wind sweeping blade 110 further includes: a frame 610 , wherein the frame 610 is hollowed out in the front-rear direction; and the baffle 500 is installed on the inner wall of the frame 610 at a fixed tilt angle.

[0038] The baffle 500 is arranged at a fixed inclination angle, such as 30° or 45°, relative to the inner wall of the sweeping blade 110, so that the wind direction of the baffle 500 remains the same under the premise that the sweeping blade 110 does not rotate left or right. When the sweeping blade 110 rotates left or right, the wind direction of the baffle 500 will rotate around the axis direction with the sweeping blade. For details, please refer to Figure 4 , 5 、6.

[0039] Further optimization, in the initial state, the baffle 500 is inclined upward at a fixed angle; when the wind sweeping blade 110 rotates along the left-right direction by a first angle, the baffle 500 is inclined downward at a fixed angle.

[0040] In order to make the upward or downward air outlet angle of the baffle related to the left and right rotation angle of the wind sweeping blade, and to adapt to different air conditioning modes. When the air conditioner is in cooling mode, such as Figure 4 , is the state of the left air outlet in the cooling mode of the air conditioner; Figure 5 , is the right air outlet state in the cooling mode of the air conditioner. Since the baffle 500 is fixedly arranged on the inner wall of the wind sweeping blade 110, the air outlet direction is upward. At this time, in the cooling left air outlet state, the first gear 300 can be rotated 90° to the cooling right air outlet state.

[0041] When the air conditioner is in heating mode, Figure 6 , which is the right air outlet state in the heating mode of the air conditioner. Since the baffle 500 is fixedly arranged on the inner wall of the sweeping blade 110, the air outlet direction is downward. Figure 5 Position: The right air outlet position in cooling mode is rotated 180°, that is, in cooling mode and heating mode, since the wind sweeping blade 110 is rotated 180° relative to the rotation axis, that is, the first gear 300 is rotated 180°, the baffle 500 in the corresponding wind sweeping blade 110 also changes from the upward air outlet state to the downward air outlet state.

[0042] Further optimized, the driving structure 120 includes: a gear box shell, which includes a gear set, the gear set includes a plurality of first gears 300, a plurality of transmission gears 310, each transmission gear 310 is meshed between two of the first gears 300; a motor 800, the output shaft of the motor 800 is connected to one of the first gears 300; a plurality of the wind sweeping blades 110 are matched and connected with the plurality of the first gears 300 in a one-to-one correspondence. The driving structure 120 is preferably a gear box shell, such as Figure 1 , arranged on the upper surface of the housing 100, the motor 800 is a forward and reverse motor 800, and the forward rotation of the motor 800 drives the wind sweeping blades 110 to rotate in the forward direction, and the reverse rotation of the motor 800 drives the wind sweeping blades 110 to rotate in the reverse direction. In order to ensure that a single motor 800 can control multiple wind sweeping blades 110 and then drive the multiple wind sweeping blades 110 to rotate at the same time, a transmission gear 310 is used between adjacent first gears 300 for meshing transmission, so that the rotation directions of the multiple first gears 300 are consistent.

[0043] Further optimization, the transmission gear 310 and the first gear 300 are of the same size, ensuring that when the motor 800 drives the first gear 300 to rotate, the meshing action of the transmission gear 310 and the first gear 300 makes the left and right swing angles of the plurality of wind sweeping blades 110 consistent.

[0044] Since the sizes of the plurality of sweeping blades 110 are the same, to ensure that the swing angles of the sweeping blades 110 are the same, the sizes of the transmission gear 310 and the first gear 300 need to be kept consistent, so that the swing angles of the plurality of sweeping blades 110 can be the same.

[0045] Further optimization also includes a limiting structure for limiting the left and right rotation angle of the wind sweeping blade 110, and the limiting structure includes: a first engaging member 200, fixedly connected to the gear box housing; a second engaging member 210, arranged on the transmission gear 310 or the first gear 300; when the driving structure 120 drives the wind sweeping blade 110 to rotate left and right and is about to exceed the preset rotation angle range, the second engaging member 210 abuts against the first engaging member 200 to limit the driving structure 120 from continuing to drive the wind sweeping blade 110 to rotate.

[0046] like Figure 2 As shown, the second engaging member 210 is fixedly mounted on the surface of the first gear 300 on the far left, and protrudes along the surface of the first gear 300. The second engaging member 210 is preferably a convex block, which acts as a engaging member through the convex block; the corresponding first engaging member 200 is arranged on the inner side of the top wall of the gear box shell, and the first engaging member 200 is also a convex block. The purpose of limiting the left and right rotation angle of the wind sweeping blade 110 is achieved through the contact between the convex blocks. In order to make the second engaging member 210 contact with the first engaging member 200 along the rotation trajectory of the first gear 300 when the first gear 300 rotates, the first engaging member 200 is arranged at the position after the first gear 300 is rotated by a predetermined angle, such as when the predetermined angle is 270°, initially, the angle formed between the first engaging member 200 and the second engaging member 210 is 270°.

[0047] The first engaging member 200 and the second engaging member 210 can be fixedly mounted on the gear and the inner wall of the gear box, respectively. Since the first engaging member 200 on the inner wall of the gear box is fixedly mounted, and the second engaging member 210 on the gear rotates with the gear, when the gear rotates to a certain angle, the first engaging member 200 cooperates with the second engaging member 210 to limit the rotation of the gear, thereby limiting the rotation of the wind sweeping blade 110. In this way, the mechanical structure can limit the rotation of the gear beyond the preset rotation range, and excessive rotation will not occur.

[0048] Further optimization, the second engaging member 210 protrudes along the circular surface of the first gear 300 or the transmission gear 310, and the first engaging member 200 protrudes along the inner side of the top wall of the gear box shell. When the left and right rotation angle of the wind sweeping blade 110 is about to exceed a preset range, the first engaging member 200 and the second engaging member 210 cooperate to limit the left and right rotation angle of the wind sweeping blade 110.

[0049] The baffle 500 is arranged at a fixed inclination angle, such as 30° or 45°, relative to the inner wall of the sweeping blade 110 , so that the air outlet direction of the baffle 500 remains consistent under the premise that the sweeping blade 110 does not rotate.

[0050] Further optimized, the first engaging member 200 includes a first limiting rib 410 and a second limiting rib 420 protruding along the inner side of the top wall of the gear box shell; in the initial state, the second engaging member 210 is fitted with the first limiting rib 410, and when the wind sweeping blade 110 is at the maximum rotation angle, the second engaging member 210 is fitted with the second limiting rib 420; there is an arc transition between the first limiting rib 410 and the second limiting rib 420.

[0051] like Figure 2 The gear cover plate 900 in the gear box is provided with five grooves 700 for installing the transmission gear 310 or the shaft where the first gear 300 is located. The first limit retaining rib 410 and the second limit retaining rib 420 are provided in the leftmost groove 700. In order to ensure that the rotation angle of the wind sweeping blade 110 is limited to 280°, the angle between the first limit retaining rib 410 and the second limit retaining rib 420 is K. For example, when the angle K is 80°, the maximum rotation angle (360-K) is 280°. Therefore, in the position shown in FIG7, the second engaging member 210 is in contact with the first limit retaining rib 410. When the wind sweeping blade 110 is at the maximum rotation angle, the second engaging member 210 is in contact with the second limit retaining rib 420. At the same time, in order to ensure that the first engaging member 200 and the second engaging member 210 can cooperate with the first limiting rib 410 and the second limiting rib 420, the first limiting rib 410 is arranged along the axial direction of the groove 700, and the radius of the circle where the arc transition between the first limiting rib 410 and the second limiting rib 420 is located is smaller than the radius of the groove 700.

[0052] Further optimized, the wind sweeping blade 110 also includes: a rotating sleeve 620, which is arranged at one end of the frame 610 close to the gear box shell; the rotating sleeve 620 cooperates with the transmission shaft where the first gear 300 is located, so that the first gear 300 drives the frame 610 to rotate left and right.

[0053] Correspondingly, in order to ensure that the frame 610 can rotate relative to the shell, a rotating sleeve 620 is set at the upper end of the frame 610. The rotating sleeve 620 cooperates with the transmission shaft. The rotating sleeve 620 and the transmission shaft can be matched with splines or flat keys to achieve stable transmission.

[0054] The present invention further provides an air conditioner, comprising: the above-mentioned air sweeping structure, the housing 100 is provided with a groove 700, the groove 700 is located in the middle of the housing 100, and the groove 700 is used to install the accommodating space of the above-mentioned air sweeping structure.

[0055] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
