Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a wind deflector support device and an air conditioner with the wind deflector support device. Background Art

[0002] A wind deflector is arranged at the air outlet of the air conditioner. The wind deflector is controlled by a motor to rotate, so as to close or open the air outlet, and conduct the air flow blown out of the air outlet in different angular directions, thereby changing the direction of the air flow blown out of the air outlet.

[0003] With the long-term use of the air conditioner, a large amount of dust will appear on the inner wall of the wind deflector and inside the air conditioner. It is necessary to disassemble the wind deflector to facilitate the cleaning of the wind deflector and the inside of the air conditioner.

[0004] In the existing air conditioner, a telescopic convex shaft is arranged at one end of the wind deflector. The telescopic convex shaft includes a rear convex shaft and a front convex shaft. A telescopic cavity is arranged inside the rear convex shaft along the length direction of the rear convex shaft. A through hole is arranged at one end of the rear convex shaft. The through hole communicates the internal space of the telescopic cavity with the external space. The inner diameter of the opening is smaller than the inner diameter of the telescopic cavity. The front convex shaft is arranged in the telescopic cavity. The front convex shaft can reciprocate in the telescopic cavity. A limiting part is also arranged in the telescopic cavity. The outer diameter of the limiting part is between the inner diameter of the telescopic cavity and the inner diameter of the through hole. The limiting part is connected to the part of the front convex shaft that is always inside the telescopic cavity. A compression spring is also arranged in the telescopic cavity. One end of the compression spring abuts against the inner wall of the telescopic cavity and the other end abuts against the limiting part. The initial state of the compression spring is to push out a part of the front convex shaft out of the telescopic cavity. The front convex shaft located outside the telescopic cavity is docked with the motor. Thus, the motor drives the front convex shaft to rotate, and the front convex shaft drives the rear convex shaft to rotate. Thus, the rear convex shaft drives the wind deflector to rotate to change the direction of the air flow blown out of the air outlet.

[0005] However, although the existing air conditioner can solve the problems of irreversible deformation and fracture of the wind deflector caused by the deformation of the wind deflector material under external force when disassembling and assembling the wind deflector by arranging the telescopic convex shaft structure at one end of the wind deflector, when the existing air conditioner controls the rotation of the wind deflector to change the direction of the air flow blown out of the air outlet, the rotational driving force acting on the wind deflector needs to be transmitted through multiple levels of the front convex shaft and the rear convex shaft, resulting in an increase in the redundant torque of the motor that gives the rotational driving force, thereby increasing the energy consumption of the motor and affecting the accuracy of driving the wind deflector to rotate. Summary of the Utility Model

[0006] To achieve the first object of the present utility model, the present utility model provides a wind deflector support device, which can avoid the risk of deformation and fracture of the wind deflector during disassembly and assembly, improve the convenience of disassembly and assembly of the wind deflector, and will not generate redundant torque on the motor that gives the driving force for the rotation of the wind deflector, thus not causing redundant energy consumption to the motor and improving the accuracy of driving the rotation of the wind deflector.

[0007] To achieve the second object of the present utility model, the present utility model provides an air conditioner having the above-mentioned wind deflector support device.

[0008] To achieve the first object of the present utility model, the present utility model provides a wind deflector support device, including a support base, a telescopic shaft, a first elastic member, a telescopic cap, a second elastic member and a third elastic member. An accommodation cavity is provided at the outer shaft end of the support base, and a limiting platform is protrudingly provided on the peripheral wall of the accommodation cavity. The floating end of the telescopic shaft is movably located in the accommodation cavity in its own axial direction, and the support end of the telescopic shaft can pass through the accommodation cavity and is used for detachably inserting into the hinge hole of the wind deflector. The first elastic member forces the telescopic shaft to move away from the bottom end of the accommodation cavity. The through hole of the telescopic cap is sleeved on the telescopic shaft. The second elastic member forces the telescopic cap to move away from the bottom end of the cavity. And a split ring eaves is protrudingly provided on the outer peripheral wall of the telescopic cap. The limiting platform is located within the opening of the split ring eaves in the circumferential direction of the telescopic shaft. The third elastic member forces the guided end of the split ring eaves to press against the limiting surface of the limiting platform in the circumferential direction of the telescopic shaft. A first inclined surface inclined away from the limiting surface is provided at the lower end of the guided end, and a second inclined surface is provided at the top end of the limiting surface. The first inclined surface can press against the second inclined surface. A guiding platform is protrudingly provided on the outer peripheral wall of the floating end. The guiding surface of the guiding platform away from the limiting surface in the circumferential direction of the telescopic shaft is inclined away from the limiting surface, and a guiding groove is provided on the side of the guiding surface close to the limiting surface of the guiding platform. The guiding groove includes a first groove section and a second groove section that are < -shaped and inclined in the circumferential direction of the telescopic shaft away from the guiding surface. The first groove section is provided close to the bottom end of the cavity in the axial direction of the telescopic shaft. A convex column is protrudingly provided on the inner peripheral wall of the through hole. The convex column can press against the guiding surface, and the convex column can slide within the first groove section or the second groove section.

[0009] As can be seen from the above solution, pressing the split ring eaves of the telescopic cap of the wind deflector support device of the present utility model towards the bottom end of the accommodation cavity. Since the first inclined surface of the original split ring eaves presses against the second inclined surface of the limiting platform, and the first inclined surface and the second inclined surface are inclined away from the limiting surface in the axial direction of the telescopic shaft, it thus forces the split ring eaves to drive the entire telescopic cap to rotate away from the limiting surface of the limiting platform in the circumferential direction of the telescopic shaft, so that the convex column of the telescopic cap presses against the upper end of the guiding surface of the telescopic shaft. At this time, the first inclined surface of the split ring eaves disengages from the second inclined surface of the limiting platform, and the third elastic member forces the guided end of the split ring eaves to press against the limiting surface of the limiting platform in the circumferential direction of the telescopic shaft.

[0010] Since the guiding surface of the telescopic shaft is inclined relative to the axial direction of the telescopic shaft away from the limiting surface of the limiting platform, as the open-loop eaves of the telescopic cap are continuously pressed towards the bottom end of the accommodating cavity, the convex column of the telescopic cap presses against and forces the guiding surface of the telescopic shaft to drive the telescopic shaft to move towards the bottom end of the accommodating cavity, so that the supporting end of the telescopic shaft moves towards the bottom end of the accommodating cavity. At the same time, the convex column is forced to drive the entire telescopic cap to rotate away from the limiting surface of the limiting platform in the circumferential direction of the telescopic shaft.

[0011] When the convex column of the telescopic cap disengages from the lower end of the guiding surface of the telescopic shaft after continuously pressing the open-loop eaves of the telescopic cap, the third elastic member immediately forces the guided end of the open-loop eaves of the telescopic cap to rotate towards the limiting surface of the limiting platform in the circumferential direction of the telescopic shaft, so that the guided end of the open-loop eaves presses against the limiting surface of the limiting platform. At the same time, the convex column of the telescopic cap rotates along the lower end surface of the guiding platform to the first opening of the first groove section of the guiding groove.

[0012] Release the pressing operation on the open-loop eaves of the telescopic cap, that is, cancel the pressing of the open-loop eaves of the telescopic cap. The first elastic member forces the telescopic shaft to move away from the bottom end of the accommodating cavity, and the second elastic member forces the telescopic cap to move away from the bottom end of the cavity. Then the convex column of the telescopic cap enters the first groove section of the guiding groove from the first opening and is slidably clamped at the connection junction of the first groove section and the second groove section of the guiding groove. After that, the first elastic member and the second elastic member jointly force the telescopic shaft and the telescopic cap to move away from the bottom end of the cavity respectively, so that the supporting end of the telescopic shaft passes through the accommodating cavity of the supporting seat and is inserted and assembled into the hinge hole of the air deflector located at the air outlet of the air outlet frame, realizing the rotatable support of the air deflector. When the motor controls the air deflector to rotate, since the third elastic member forces the guided end of the open-loop eaves to press against the limiting surface of the limiting platform in the circumferential direction of the telescopic shaft, and the convex column of the telescopic cap is clamped at the connection junction of the first groove section and the second groove section of the guiding groove, the telescopic shaft will not rotate with the air deflector, so that the rotational driving force of the motor directly acts to drive the air deflector to rotate, without generating extra torque on the motor, and thus will not cause extra energy consumption to the motor.

[0013] When the air deflector needs to be removed, press the supporting end of the telescopic shaft towards the bottom end of the accommodating cavity. Then the convex column clamped at the connection junction of the first groove section and the second groove section of the guiding groove slides into the second groove section of the telescopic shaft. And as the supporting end of the telescopic shaft is continuously pressed towards the bottom end of the accommodating cavity, and under the action of the second elastic member forcing the telescopic cap to move away from the bottom end of the accommodating cavity and the third elastic member forcing the guided end of the open-loop eaves to press against the limiting surface of the limiting platform in the circumferential direction of the telescopic shaft, the convex column of the telescopic cap slides out from the second opening of the second groove section, and the first inclined surface of the telescopic cap presses against the second inclined surface of the limiting platform. And under the action of the third elastic member, the telescopic cap is restricted and supported at the opening of the accommodating cavity of the supporting seat in the circumferential direction of the telescopic shaft. At this time, the supporting end of the telescopic shaft disengages from the hinge hole of the air deflector, thus completing the disassembly of the air deflector. After that, the telescopic shaft resets under the action of the first elastic member.

[0014] Therefore, the air deflector support device of the present utility model can avoid the risk of deformation and fracture of the air deflector during disassembly and assembly, improve the convenience of disassembly and assembly of the air deflector, and will not generate extra torque on the motor that gives the rotational driving force to the air deflector, thus not causing extra energy consumption to the motor and improving the accuracy of driving the air deflector to rotate.

[0015] A further solution is that the vertical guide surface of the guiding platform, which is away from the limiting surface in the circumferential direction of the telescopic shaft, extends in the axial direction of the telescopic shaft. The vertical guide surface is connected to one end of the guiding surface that is away from the supporting end in the axial direction of the telescopic shaft, and the convex column can be pressed against the vertical guide surface.

[0016] A further solution is that the guiding platform protrudes from the first open end of the first groove section away from the second groove section and is provided with a guiding surface. The guiding surface is connected to one end of the first open end that is away from the guiding surface in the circumferential direction of the telescopic shaft, and the guiding surface extends away from the first groove section in the axial direction of the telescopic shaft. The convex column can be pressed against the guiding surface.

[0017] A further solution is that the guiding platform is provided with a guiding groove. The guiding groove communicates with the second open end of the second groove section away from the first groove section, and the guiding groove extends away from the second groove section in the axial direction of the telescopic shaft. The convex column can slide in the guiding groove.

[0018] A further solution is that the upper end of the guided end is provided with a third inclined surface that is inclined away from the limiting surface.

[0019] A further solution is that the inclination angle of the second groove section is the same as the inclination angle of the second inclined surface; and / or, the inclination angle of the first groove section relative to the radial direction of the telescopic shaft is between 105° and 135°.

[0020] A further solution is that the third elastic member is an elastic snap ring. The open-loop eaves are provided with a limiting groove at an open end away from the guided end in the circumferential direction of the telescopic shaft. The forced end of the limiting groove extends towards the guided end in the circumferential direction of the telescopic shaft. The first snap ring end of the elastic snap ring is located in the limiting groove and is pressed against the forced end, and the second snap ring end of the elastic snap ring is pressed against the blocking surface of the limiting platform. The blocking surface and the limiting surface are oppositely arranged in the circumferential direction of the telescopic shaft.

[0021] A further solution is that the first elastic member is a first compression spring. The first compression spring is located in the accommodation cavity, and both ends of the first compression spring are pressed between the floating end and the bottom end of the cavity; and / or, the second elastic member is a second compression spring. The second compression spring is located in the accommodation cavity, and both ends of the second compression spring are pressed between the lower end of the telescopic cap away from the open-loop eaves and the bottom end of the cavity.

[0022] A further solution is that the bottom end of the cavity protrudes in the axial direction of the telescopic shaft and is provided with a rectangular rod. The rectangular hole of the telescopic shaft is movably sleeved on the rectangular rod.

[0045] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. Specific embodiments

[0046] Refer to Figures 1 to 11 , this embodiment discloses an air conditioner, including an air outlet frame 11, an air deflector 12, a motor (not labeled), and an air deflector support device 20. The air deflector 12 is rotatably supported on the air outlet frame 11, the motor can control the rotation of the air deflector 12, the support base 21 of the air deflector support device 20 is arranged on the air outlet frame 11, and the support end 241 of the telescopic shaft 24 of the air deflector support device 20 is detachably inserted into the hinge hole 121 of the air deflector 12.

[0047] Among them, the air deflector support device 20 of this embodiment includes a support base 21, a telescopic shaft 24, a first elastic member, a telescopic cap 23, a second elastic member, and a third elastic member. An accommodation cavity 211 is formed at the outer shaft end of the support base 21. A limiting platform 212 protrudes from the peripheral wall of the accommodation cavity 211. The floating end 242 of the telescopic shaft 24 is movably located within the accommodation cavity 211 in its own axial direction, and the support end 241 of the telescopic shaft 24 can penetrate out of the accommodation cavity 211 and is used for detachably plugging into the hinge hole 121 of the air deflector 12. The first elastic member forces the telescopic shaft 24 to move away from the bottom end 2111 of the accommodation cavity 211.

[0048] Moreover, the through hole 232 of the telescopic cap 23 of this embodiment is sleeved on the telescopic shaft 24. The second elastic member forces the telescopic cap 23 to move away from the bottom end 2111 of the accommodation cavity 211. An open-loop eaves 231 protrudes from the outer peripheral wall of the telescopic cap 23. The limiting platform 212 is located within the opening of the open-loop eaves 231 in the circumferential direction of the telescopic shaft 24. The third elastic member forces the guided end 2312 of the open-loop eaves 231 to press against the limiting surface 2123 of the limiting platform 212 in the circumferential direction of the telescopic shaft 24. A first inclined surface 2313 that inclines away from the limiting surface 2123 is provided at the lower end of the guided end 2312 of the open-loop eaves 231. A second inclined surface 2122 is provided at the top end of the limiting surface 2123. The first inclined surface 2313 can press against the second inclined surface 2122.

[0049] In addition, a guiding platform 244 protrudes from the outer peripheral wall of the floating end 242 of this embodiment. The guiding surface 2441 of the guiding platform 244 that is away from the limiting surface 2123 in the circumferential direction of the telescopic shaft 24 is inclined relative to the axial direction of the telescopic shaft 24 away from the limiting surface 2123. A guiding groove 2440 is formed on the side of the guiding platform 244 where the guiding surface 2441 is close to the limiting surface 2123. The guiding groove 2440 includes a first groove section 2442 and a second groove section 2443 that are < -shaped and inclined in the circumferential direction of the telescopic shaft 24 away from the guiding surface 2441. The first groove section 2442 is arranged close to the bottom end 2111 of the accommodation cavity 211 in the axial direction of the telescopic shaft 24. A convex column 233 protrudes from the inner peripheral wall of the through hole 232. The convex column 233 can press against the guiding surface 2441, and the convex column 233 can slide within the first groove section 2442 or the second groove section 2443.

[0050] See Figure 12 and Figure 13, press the open-loop eaves 231 of the telescopic cap 23 of the air guide plate support device 20 of this embodiment towards the bottom end 2111 of the accommodation cavity 211. Since the first inclined surface 2313 of the original open-loop eaves 231 abuts against the second inclined surface 2122 of the limiting platform 212, and the first inclined surface 2313 and the second inclined surface 2122 are inclined away from the limiting surface 2123 in the axial direction of the telescopic shaft 24, it forces the open-loop eaves 231 to drive the entire telescopic cap 23 to rotate away from the limiting surface 2123 of the limiting platform 212 in the circumferential direction of the telescopic shaft 24, so that the convex column 233 of the telescopic cap 23 abuts against the upper end of the guiding surface 2441 of the telescopic shaft 24. At this time, the first inclined surface 2313 of the open-loop eaves 231 disengages from the second inclined surface 2122 of the limiting platform 212, and the third elastic member forces the guided end 2312 of the open-loop eaves 231 to abut against the limiting surface 2123 of the limiting platform 212 in the circumferential direction of the telescopic shaft 24.

[0051] See Figures 14 to 16 , since the guiding surface 2441 of the telescopic shaft 24 is inclined away from the limiting surface 2123 of the limiting platform 212 in the axial direction of the telescopic shaft 24, along with continuously pressing the open-loop eaves 231 of the telescopic cap 23 towards the bottom end 2111 of the accommodation cavity 211, the convex column 233 of the telescopic cap 23 abuts and forces the guiding surface 2441 of the telescopic shaft 24 to drive the telescopic shaft 24 to move towards the bottom end 2111 of the accommodation cavity 211, so that the supporting end 241 of the telescopic shaft 24 moves towards the bottom end 2111 of the accommodation cavity 211, and at the same time forces the convex column 233 to drive the entire telescopic cap 23 to rotate away from the limiting surface 2123 of the limiting platform 212 in the circumferential direction of the telescopic shaft 24.

[0052] See Figures 17 to 18 , when continuously pressing the open-loop eaves 231 of the telescopic cap 23 so that the convex column 233 of the telescopic cap 23 disengages from the guiding surface 2441 of the telescopic shaft 24 from the lower end of the guiding surface 2441 of the telescopic shaft 24, the third elastic member immediately forces the guided end 2312 of the open-loop eaves 231 of the telescopic cap 23 to rotate towards the limiting surface 2123 of the limiting platform 212 in the circumferential direction of the telescopic shaft 24, so that the guided end 2312 of the open-loop eaves 231 abuts against the limiting surface 2123 of the limiting platform 212, and at the same time makes the convex column 233 of the telescopic cap 23 rotate along the lower end surface of the guiding platform 244 to the first open end of the first groove section 2442 of the guiding groove 2440.

[0053] See Figures 19 to 20, release the pressing operation on the open-loop eaves 231 of the telescopic cap 23, that is, cancel the pressing of the open-loop eaves 231 of the telescopic cap 23. The first elastic member forces the telescopic shaft 24 to move away from the bottom end 2111 of the accommodating cavity 211, and the second elastic member forces the telescopic cap 23 to move away from the bottom end 2111. Then, the convex column 233 of the telescopic cap 23 enters the first groove section 2442 of the guiding groove 2440 from the first opening, and is slidably clamped at the connection junction of the first groove section 2442 and the second groove section 2443 of the guiding groove 2440. After that, the first elastic member and the second elastic member jointly force the telescopic shaft 24 and the telescopic cap 23 to move away from the bottom end 2111, so that the supporting end 241 of the telescopic shaft 24 passes through the accommodating cavity 211 of the supporting seat 21 and is inserted and assembled into the hinge hole 121 of the air deflector 12 at the air outlet of the air outlet frame 11, realizing the rotatable support of the air deflector 12. When the motor controls the rotation of the air deflector 12, since the third elastic member forces the guided end 2312 of the open-loop eaves 231 to press against the limiting surface 2123 of the limiting platform 212 in the circumferential direction of the telescopic shaft 24, and the convex column 233 of the telescopic cap 23 is clamped at the connection junction of the first groove section 2442 and the second groove section 2443 of the guiding groove 2440, the telescopic shaft 24 will not rotate with the air deflector 12, so that the rotation driving force of the motor directly acts to drive the air deflector 12 to rotate, without generating extra torque on the motor, and thus will not cause extra energy consumption to the motor.

[0054] See Figure 21 , when removing the air deflector 12, press the supporting end 241 of the telescopic shaft 24 towards the bottom end 2111 of the accommodating cavity 211. Then, the convex column 233 clamped at the connection junction of the first groove section 2442 and the second groove section 2443 of the guiding groove 2440 slides into the second groove section 2443 of the telescopic shaft 24. Along with continuously pressing the supporting end 241 of the telescopic shaft 24 towards the bottom end 2111 of the accommodating cavity 211, and under the action of the second elastic member forcing the telescopic cap 23 to move away from the bottom end 2111 of the accommodating cavity 211 and the third elastic member forcing the guided end 2312 of the open-loop eaves 231 to press against the limiting surface 2123 of the limiting platform 212 in the circumferential direction of the telescopic shaft 24, the convex column 233 of the telescopic cap 23 slides out from the second opening of the second groove section 2443, and the first inclined surface 2313 of the telescopic cap 23 presses against the second inclined surface 2122 of the limiting platform 212, and under the action of the third elastic member, the telescopic cap 23 is circumferentially restricted and supported at the opening of the accommodating cavity 211 of the supporting seat 21 on the telescopic shaft 24. At this time, the supporting end 241 of the telescopic shaft 24 disengages from the hinge hole 121 of the air deflector 12, thus completing the removal of the air deflector 12. After that, the telescopic shaft 24 resets under the action of the first elastic member.

[0055] Therefore, the air deflector support device 20 of this embodiment can avoid the risks of deformation and fracture of the air deflector 12 during disassembly and assembly, improve the convenience of disassembly and assembly of the air deflector 12, and will not generate redundant torque on the motor that gives the air deflector 12 rotational driving force, thus will not cause redundant energy consumption to the motor, and improve the accuracy of driving the air deflector 12 to rotate.

[0056] To ensure that the convex column 233 of the telescopic cap 23 rotates precisely and smoothly along the lower end surface of the guide platform 244 to the first open end of the first groove section 2442 of the guide groove 2440, in this embodiment, the vertical guide surface 2446 of the guide platform 244 that is far from the limiting surface 2123 in the circumferential direction of the telescopic shaft 24 extends in the axial direction of the telescopic shaft 24. The vertical guide surface 2446 is connected to one end of the guide surface 2441 that is far from the support end 241 in the axial direction of the telescopic shaft 24, and the convex column 233 can be pressed against the vertical guide surface 2446.

[0057] To ensure that the convex column 233 of the telescopic cap 23 enters the first groove section 2442 precisely and smoothly from the first open end of the first groove section 2442, in this embodiment, the guide platform 244 protrudes from the first open end of the first groove section 2442 that is far from the second groove section 2443 and is provided with a guiding surface 2445. The guiding surface 2445 is connected to one end of the first open end that is far from the guide surface 2441 in the circumferential direction of the telescopic shaft 24, and the guiding surface 2445 extends far from the first groove section 2442 in the axial direction of the telescopic shaft 24. The convex column 233 can be pressed against the guiding surface 2445, and the guiding surface 2445 plays a blocking role for the convex column 233 in the circumferential direction of the telescopic shaft 24.

[0058] To ensure that the convex column 233 of the telescopic cap 23 can be precisely and smoothly pressed against the upper end of the guide surface 2441 after coming out from the second open end of the second groove section 2443, in this embodiment, the guide platform 244 is provided with a guiding groove 2444. The guiding groove 2444 communicates with the second open end of the second groove section 2443 that is far from the first groove section 2442, and the guiding groove 2444 extends far from the second groove section 2443 in the axial direction of the telescopic shaft 24, and the convex column 233 can slide in the guiding groove 2444.
