[0002] Air conditioners have become an indispensable need for thousands of households in the hot summer. However, when the air conditioner sweeps the air left and right, the sweeping direction is not accurate enough, which makes the air conditioner's left and right sweeping accuracy not high, bringing great inconvenience. Therefore, it is very necessary to solve the problem of low air sweeping direction accuracy of the air conditioner. Summary of the invention

[0003] Therefore, the present invention provides an air conditioner and an air guide device thereof, which solve the problem of low precision of air sweeping direction and improve the accuracy of air supply.

[0004] To achieve the purpose of the present invention, the present invention provides an air guide device for an air conditioner, the air conditioner is provided with an air outlet, the air guide device includes: an air guide tube, the air guide tube is provided at the air outlet, and can be switched between a first state and a second state; the air guide tube covers the air outlet in the first state, and extends outward from the air outlet in the second state to guide the air inside the air conditioner to the outside, wherein the air guide tube switches from the first state to the second state by a rotating and extending action, and switches from the second state to the first state by a contracting and rotating action.

[0005] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the air guide tube can be switched between two states to meet the needs of users in different environments. When the air guide tube is in the first state, the air guide tube covers the air outlet to prevent dust from entering the interior of the air conditioner, thereby ensuring the air outlet effect of the air conditioner; when the air guide tube is in the second state, the air guide tube extends outward from the air outlet to discharge the air inside the air conditioner. The air guide tube switches to the second state by rotating and extending, thereby reducing the external space occupied by the air conditioner.

[0006] In one technical solution of the present invention, the wind guide device also includes: a wind sweeping connecting rod, which is connected to the wind sweeping connecting rod, a rotating driving device, which is connected to the wind sweeping connecting rod and is used to drive the wind sweeping connecting rod to swing back and forth in the direction in which its own axis extends; a rotating device, which is arranged adjacent to the wind guide tube, the rotating device is connected to the wind sweeping connecting rod, the wind sweeping connecting rod swings back and forth, driving the rotating device to rotate, thereby driving the air guide tube to rotate.

[0007] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the air guide tube is fixed on the air sweeping connecting rod, and the rotary driving device drives the air sweeping connecting rod to swing back and forth along the direction in which its own axis extends, thereby driving the air guide tube to swing, thereby realizing the air sweeping function in the left and right directions. When the air sweeping connecting rod swings, the driving rotating device drives the air guide tube to rotate, thereby switching the air guide tube between the first state and the second state. The air sweeping connecting rod and the rotating device are driven to rotate by the rotary driving device, thereby realizing the integration of the air guide device, which not only realizes the air sweeping and switching state functions, but also occupies less internal space of the air conditioner.

[0008] In one technical solution of the present invention, the rotary drive device includes: a rotary motor, which is provided with a first gear; a threaded member, which is sleeved on the end of the wind sweeping connecting rod; wherein the first gear and the threaded member are meshed with each other, driving the wind sweeping connecting rod to swing back and forth along the direction in which its own axis extends, thereby driving the air guide tube to swing.

The rotating motor can accurately drive the speed and number of revolutions of the gear rotation. When the gear is meshed with the threaded member, the swing amplitude of the wind sweeping connecting rod can be accurately controlled. At the same time, the rotating motor is cheap and easy to obtain, and replacement parts are easy to obtain, which reduces the cost of maintenance and replacement. After a long period of operation, the rotating motor can still ensure the rotation accuracy, making the air guide device more reliable and durable.

[0010] In one technical solution of the present invention, the rotating device includes: a mounting portion, the mounting portion is arranged on the wind sweeping connecting rod, the wind sweeping connecting rod is connected to the air guide tube through the mounting portion, and a fixing member is arranged at the bottom of the wind sweeping connecting rod, the wind sweeping connecting rod and the fixing member are connected to each other, wherein the wind sweeping connecting rod and the fixing member can slide relative to each other so that there will be no position interference when the air guide tube rotates.

[0011] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the wind sweeping connecting rod is connected to the wind guide tube by fasteners, the fixing method is relatively simple, easy to install and disassemble, the fasteners are universal parts, cheap and easy to obtain, and the cost is lower. A fixing piece is provided at the bottom of the wind sweeping connecting rod, and the wind sweeping connecting rod and the fixing piece can slide relative to each other, providing sufficient space for the wind guide tube when rotating, avoiding the position interference caused by the wind guide tubes touching each other, and affecting the effect of the switching state of the wind guide device.

[0012] In one technical solution of the present invention, the air guide device is connected to the air conditioner via an air guide bracket; wherein, the air guide bracket is horizontally arranged at the air outlet, the air guide tube is provided with a rotating shaft, the air guide bracket is provided with a mounting piece, the rotating shaft is connected to the air guide bracket via the mounting piece, and when the air guide tube rotates, it rotates with the rotating shaft as the rotation center.

[0013] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the air guide device is fixed on the air conditioner through the air guide bracket, which is convenient for assembly and disassembly; the air guide bracket is parallel to the plane where the air outlet is located, which is convenient for the air guide tube to cover the air outlet in the first state, reducing the entry of dust and preventing dust from affecting the air quality of the air conditioner; when the air guide tube extends from the air outlet and switches to the second state, the air inside the air conditioner is guided out to the outside of the air conditioner. When the air guide tube switches between the first state and the second state, it rotates around the rotating shaft as the center; the rotating shaft is connected to the mounting member and fixed to the air guide bracket, which prevents the air guide tube from being displaced after rotation, thereby affecting the air guiding effect.

[0014] In one technical solution of the present invention, the air guide device also includes: a wind sweeping connecting rod, which is connected to the air guide tube; a telescopic driving device, which is connected to the wind sweeping connecting rod and is used to drive the wind sweeping connecting rod to rotate along its own axis, so that the air guide tube can be extended or retracted relative to the air outlet by rotating around the wind sweeping connecting rod.

[0015] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the telescopic driving device drives the air guide tube to extend or retract relative to the air outlet, so that the air guide tube is retracted at the air outlet in the first state, covering the air outlet to prevent dust from entering and affecting the air outlet effect; when the air guide tube is in the second state, the air guide tube extends from the air outlet to discharge the air inside the air conditioner, thereby achieving the air guiding effect.

[0016] In one technical solution of the present invention, the telescopic drive device includes: a telescopic motor, the telescopic motor is provided with a third gear and a second gear, the second gear is sleeved on the wind sweeping connecting rod, wherein the third gear is used to drive the second gear transmission so that the second gear drives the wind sweeping connecting rod to rotate around its own axis.

When the third gear drives the second gear to rotate, the rotation speed of the second gear can be controlled. The second gear is mounted on the wind sweeping connecting rod. When the second gear rotates, it drives the wind sweeping connecting rod to rotate along the direction of its own axis, so that the air guide tube fixed on the wind sweeping connecting rod swings up and down, achieving the effect of sweeping the wind up and down.

[0018] In a technical solution of the present invention, the telescopic driving device further includes: a transition gear, which is arranged between the second gear and the third gear, and the transition gear is respectively meshed with the second gear and the third gear, so that the third gear drives the second gear.

[0019] Compared with the prior art, the technical effect achieved by adopting this technical solution is: the telescopic motor drives the third gear, so that the third gear and the transition gear are meshed with each other, and the transition gear is meshed with the second gear, thereby driving the second gear to rotate. The space inside the air conditioner is small, and the direct meshing of the second gear and the third gear will cause the third gear to interfere with the first gear. Therefore, a transition gear is set between the second gear and the third gear to solve the problem of position interference between the third gear and the first gear, and avoid the wind sweeping connecting rod from rotating more smoothly.

[0020] In a technical solution of the present invention, two groups of air guide devices are provided, and the air guide tubes of the two groups of air guide devices rotate in opposite directions so as to avoid interference when the air guide tubes rotate.

[0021] Compared with the prior art, the technical effect achieved by adopting this technical scheme is as follows: two sets of air guide devices are arranged at the air outlet of the air conditioner. Since the air outlet is long, if only one set of air guide devices is arranged at the air outlet, the wind sweeping connecting rod of the air guide device is prone to breakage. Therefore, two sets of air guide devices are arranged at the air outlet to increase the strength of the wind sweeping connecting rod and improve its service life. The air guide device is provided with multiple air guide tubes, which increases the air outlet of the air conditioner. The air guide tubes of the two sets of air guide devices rotate in opposite directions and can supply air in two directions at the same time, thereby improving the user experience.

[0022] The present invention also provides an air conditioner, which comprises: an air conditioner body; an air outlet; a wind guide device arranged on the air conditioner body; and the wind guide device is arranged on the air outlet.

[0023] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the air conditioner of the present invention includes the air guide device of any technical solution of the present invention, therefore, it has all the beneficial effects of the air guide device of any technical solution of the present invention, which will not be repeated here.

[0024] After adopting the technical solution of the present invention, the following technical effects can be achieved:

[0025] (1) The air guide tube can be switched between two states. When the air guide tube is in the first state, the air guide tube covers the air outlet to prevent dust from entering the air conditioner.

[0026] (2) The rotary motor can accurately drive the gear to rotate at a certain speed and number of revolutions. When the gear and the threaded member are meshed, the swing amplitude of the wind sweeping connecting rod can be accurately controlled. At the same time, the motor is cheap and easy to obtain, making it easy to obtain replacement parts.

[0027] (3) The space inside the air conditioner is small, and the direct meshing of the second gear and the third gear will cause the third gear to interfere with the first gear. Therefore, a transition gear is set between the second gear and the third gear to solve the problem of position interference between the third gear and the first gear and prevent the wind sweeping connecting rod from rotating more smoothly.

DETAILED DESCRIPTION

[0043] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] An embodiment of the present invention provides an air guide device, which includes: an air guide tube 120, which is arranged at the air outlet and can be switched between a first state and a second state; the air guide tube 120 covers the air outlet in the first state, and extends outward from the air outlet in the second state to guide the air inside the air conditioner outward; wherein the air guide tube 120 switches from the first state to the second state by a rotating and extending action, and switches from the second state to the first state by a contracting and rotating action.

[0045] Specifically, as attached Figure 1 As shown, the air guide tube 120 is arranged at the air outlet 410, and the air guide tube switches between the first state and the second state. When the air guide tube 120 switches to the first state, the air guide tube 120 covers the air outlet 410 to prevent dust in the air from entering the air conditioner and affecting the use effect of the air conditioner. At the same time, the air guide tube 120 is stored at the air outlet 410 to reduce the occupied space and make the air conditioner more beautiful. When the air guide tube 120 switches to the second state, as shown in the attached Figure 2 As shown, the air guide tube 120 extends outward from the air outlet to guide the air inside the air conditioner to the outside, thereby improving the indoor air quality.

[0046] Specifically, the wind guide device also includes: a wind sweeping connecting rod 110, which is connected to the wind sweeping connecting rod 110 and is connected to the wind guide tube 120; a rotating driving device 200, which is connected to the wind sweeping connecting rod 110 and is used to drive the wind sweeping connecting rod 110 to swing back and forth in the direction in which its own axis extends; a rotating device 230, which is arranged adjacent to the wind guide tube 120 and is connected to the wind sweeping connecting rod 110. The wind sweeping connecting rod 110 swings back and forth, driving the rotating device 230 to rotate, thereby driving the air guide tube 110 to rotate.

[0047] Specifically, as attached Figure 4 As shown, the air guide tube 120 is fixed on the wind sweeping link 110, and the rotation driving device 200 is arranged at the end of the wind sweeping link 110, driving the wind sweeping link 110 to swing back and forth along its own axial direction, thereby driving the air guide tube 120 to swing. When the wind sweeping link 110 swings back and forth, the driving rotation device 230 rotates, so that the air guide tube 120 rotates. In the process of switching the air guide tube 120 from the first state to the second state, the air outlet 410 of the air guide tube 120 extends outward, thereby discharging the air inside the air conditioner to the outside.

[0048] Specifically, the rotary drive device 200 includes: a rotary motor 210, which is provided with a first gear 211; a threaded member 220, which is sleeved on the end of the wind sweeping connecting rod 110; wherein the first gear 211 and the threaded member 220 are engaged with each other, driving the wind sweeping connecting rod 110 to swing back and forth along the direction in which its own axis extends, thereby driving the air guide tube 120 to swing.

[0049] As attached Figure 5 As shown, the rotating motor 210 drives the first gear 211 to rotate, and the first gear 211 and the threaded member 220 are meshed with each other, driving the wind sweeping connecting rod 110 to move in the direction in which the axis extends. The rotating motor 210 controls the rotation direction of the first gear 211 through the forward rotation and reverse rotation of the motor, thereby realizing the reciprocating swing of the wind sweeping connecting rod 110. The transmission mode in which the rotating motor 210 drives the first gear 211 to mesh with the threaded member 230 makes the rotation speed of the first gear 211 more stable and the transmission accuracy higher. At the same time, the gear meshing structure is relatively simple, the production and assembly efficiency is higher, and the production cost is lower.

[0050] Specifically, the rotating device 230 includes: a mounting portion 231, the mounting portion 231 is arranged on the wind sweeping link 110, the wind sweeping link 110 is connected to the air guide tube 120 through the mounting portion 231, the fixing member 421 is arranged at the bottom of the wind sweeping link 110, the wind sweeping link 110 and the fixing member 111 are connected to each other, wherein the wind sweeping link 110 and the fixing member 111 can slide relative to each other to avoid position interference when the air guide tube 120 rotates.

[0051] As attached Figure 6As shown, the mounting portion 231 is disposed on the wind sweeping connecting rod 110. Specifically, the mounting portion 231 is a circular through hole. Figure 7 As shown, the mounting portion 231 is connected to the air guide tube 120 by fasteners, which is convenient for installation and disassembly. The fasteners are cheap and easy to obtain, which reduces the production cost. The bottom of the wind sweeping connecting rod 110 is provided with a fixing member 111, and the fixing member 111 is provided with a waist-shaped hole. Figure 8 As shown, when the air guide tube 120 switches from the first state to the second state, the air guide tube 120 rotates with the rotating shaft 101 as the rotation center, and at the same time, the wind sweeping bracket 110 is provided with a pin, which is embedded in the waist-shaped hole of the fixing member 111. When the air guide tube 120 rotates, the pin of the wind sweeping bracket 110 slides back and forth in the waist-shaped hole of the fixing member 111, so as to avoid position interference when the air guide tube 120 rotates, resulting in the air guide tube 120 rotating unsmoothly. The pin slides in the waist-shaped hole, and the structure is relatively simple and easy to install. There is no need to add an additional motor for driving, and the cost is lower. At the same time, the structure is also more compact and occupies less space.

[0052] For example, the air guide device is connected to the air conditioner via an air guide bracket 420; wherein the air guide bracket 420 is horizontally arranged at the air outlet 410, the air guide tube 120 is provided with a rotating shaft 101, the air guide bracket 420 is provided with a mounting member 421, the rotating shaft 101 is connected to the air guide bracket 420 via the mounting member 421, and when the air guide tube 120 rotates, it rotates with the rotating shaft 101 as the rotation center.

[0053] As attached Figure 3 As shown, the rotating shaft 101 is disposed inside the air guide tube 120, and the rotating shaft 101 is connected to the air guide bracket 420. Figure 3 The rotating shaft 101 shown passes through the through hole of the mounting member 421 to fix the air guide tube 120 on the air guide bracket 420. When the air guide tube 120 switches between the first state and the second state, the air guide tube 120 rotates with the rotating shaft 101 as the rotation center, so that after the air guide tube 120 stops rotating, it will not deviate from the original position and interfere with other components. At the same time, the rotating shaft 101 plays a role in fixing the air guide tube 120 to prevent the air guide tube 120 from being separated from the air outlet 410, so that the air conditioner is safer during operation. Figure 6 As shown, the air guide device is fixed on the air guide bracket 420, which facilitates fixing the air guide device at the air outlet 410 of the air conditioner.

[0054] For example, the wind guide device also includes: a wind sweeping link 110, which is connected to the wind sweeping link 110 and an air guide tube 120; a telescopic drive device 300, which is connected to the wind sweeping link 110 and is used to drive the wind sweeping link 110 to rotate along its own axis, so that the air guide tube 120 can be extended or retracted relative to the air outlet 410 by rotating around the wind sweeping link 110.

[0055] As attached Figure 5 As shown, the telescopic drive device 300 is arranged adjacent to the rotation drive device 200, the telescopic motor 310 drives the third gear 330 to rotate, the second gear 320 is sleeved on the end of the wind sweeping link 110, and there is a gap between the second gear 320 and the threaded member 220 to avoid position interference between the second gear 320 and the first gear 211, and the third gear 330 drives the second gear 320 to rotate, thereby driving the wind sweeping link 110 to rotate around the direction of its own axis, wherein the wind guide tube 120 is fixed on the wind sweeping link 110, when the wind sweeping link 110 rotates around the direction of its own axis, the wind guide tube 120 is driven to swing, and the telescopic motor 310 controls the rotation direction of the third gear 330 by the forward rotation and reverse rotation of the telescopic motor, and drives the wind sweeping link 110 to reciprocate around its own axis, thereby realizing the extension or contraction of the wind guide tube 120 relative to the air outlet.

[0056] For example, the telescopic driving device 300 also includes: a transition gear 340, which is arranged between the second gear 320 and the third gear 330, and the transition gear 340 is respectively engaged with the second gear 320 and the third gear 330, so that the third gear 330 drives the second gear 320.

[0057] Specifically, as attached Figure 5 As shown, the transition gear 340 is arranged between the second gear 320 and the third gear 330 to prevent the first gear 311 and the third gear 330 from interfering with each other and affecting the rotation of the gears. The telescopic motor 310 drives the third gear 330 to rotate, and the third gear 330 and the transition gear 340 are meshed with each other, driving the transition gear 340 to rotate. The second gear 320 and the transition gear 340 are meshed with each other, so that the wind sweeping connecting rod 110 rotates as the second gear 320 rotates.

[0058] For example, two groups of air guide devices are provided, and the air guide tubes 120 of the two groups of air guide devices rotate in opposite directions, so that the air guide tubes 120 avoid interference when rotating.

[0059] As attached Figure 8 As shown, there are two groups of air guide devices, each of which is provided with three air guide tubes 120. If one group of air guide tubes 120 is provided at the air outlet 410, the wind sweeping connecting rod 110 is very likely to break. In order to enhance the strength of the wind sweeping connecting rod 110, two groups of air guide devices are provided at the air outlet 410. At the same time, the two groups of air guide devices are provided with a plurality of air guide tubes 120, thereby increasing the air volume of the air conditioner. Figure 7 As shown, the air guide tubes 120 of the two sets of air guide devices rotate in opposite directions, and can sweep air from the left and right sides at the same time, resulting in a better air supply effect.

[0060] The present invention further provides an air conditioner, which includes: an air conditioner body 400 , an air outlet 410 , which is disposed on the air conditioner body 100 ; and an air guide device 100 , which is disposed at the air outlet 410 .

[0061] As attached Figure 2 As shown, the air conditioner specifically includes: an air conditioner body 400, an air outlet 410 and an air guide device 100, wherein the air conditioner of the present invention includes the air guide device of the air conditioner of any technical solution of the present invention, therefore, it has all the beneficial effects of the air guide device of any technical solution of the present invention, which will not be repeated here.

[0062] As attached Fig. 9 To Attachment Fig.12 As shown, the air guide tube 120 switches from the first state to the second state, thereby guiding the air inside the air conditioner to the outside.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
