Description

Technical Field

[0001] The present application belongs to the technical field of air conditioners, and specifically relates to an opening and closing mechanism of a double air guide plate of an air conditioner and an indoor unit of an air conditioner. Background Art

[0002] A wall-mounted air conditioner is a commonly used household air conditioner. A wall-mounted air conditioner is also called a split air conditioner. It includes an indoor unit and an outdoor unit. The indoor unit is usually installed on the indoor wall, and the air outlet of the indoor unit is usually equipped with an air guide plate.

[0003] An air outlet of an indoor unit on the market is equipped with two air guide plates. When the air conditioner is turned on, the two air guide plates move horizontally and away from each other to open the air outlet of the indoor unit. When the air conditioner is turned off, the two air guide plates move horizontally and closer to each other until they abut against each other to close the air outlet of the indoor unit.

[0004] Since the two air guide plates are driven by a separate set of driving mechanisms, the structure of the indoor unit is relatively complex and the manufacturing cost of the air conditioner is relatively high. Utility Model Content

[0005] In order to solve the above-mentioned problems in the prior art, that is, to reduce the number of air guide plate driving mechanisms, simplify the structure of the indoor unit, and reduce the manufacturing cost of the air conditioner, the present application provides an air conditioner double air guide plate opening and closing mechanism and an air conditioner indoor unit. The overall driving method is to use a set of driving mechanisms to simultaneously drive the two air guide plates to move closer to or away from each other to close or open the air outlet of the indoor unit.

[0006] In a first aspect, an embodiment of the present application provides an air-conditioning double air guide plate opening and closing mechanism, comprising: a mounting base plate, used to be arranged inside the air outlet of the air-conditioning indoor unit casing; a first sliding plate, slidably connected to the mounting base plate; a second sliding plate, slidably connected to the mounting base plate; a first air guide plate, arranged on the first sliding plate; a second air guide plate, arranged on the second sliding plate, for cooperating with the first air guide plate to jointly open or close the air outlet; and a driving mechanism, arranged on the mounting base plate, for simultaneously driving the first sliding plate and the second sliding plate to slide on the mounting base plate.

[0007] By adopting the above technical solution, when the air conditioner is turned on, the driving mechanism simultaneously drives the first sliding plate and the second sliding plate to slide and move away from each other, and the first sliding plate and the second sliding plate respectively drive the first air guide plate and the second air guide plate to move away from each other to open the air outlet of the indoor unit. When the air conditioner is turned off, the driving mechanism simultaneously drives the first sliding plate and the second sliding plate to slide and move closer to each other, and the first sliding plate and the second sliding plate respectively drive the first air guide plate and the second air guide plate to move closer to each other until they are pressed against each other to close the air outlet of the indoor unit. Since the overall driving method is to use a set of driving mechanisms to simultaneously drive the two air guide plates to move closer to or away from each other, compared with the related art, the number of air guide plate driving mechanisms is reduced, the structure of the indoor unit is simplified, and the manufacturing cost of the air conditioner is reduced.

[0008] In the optional technical solution of the above-mentioned air-conditioning double air guide plate opening and closing mechanism, the driving mechanism includes: a driving motor, which is arranged on the mounting base; a driving gear, which is coaxially arranged on the output shaft of the driving motor; a first driving rack, which is arranged on the first sliding plate and meshed with the driving gear; and a second driving rack, which is arranged on the second sliding plate and meshed with the driving gear.

[0009] By adopting the above technical solution, the driving motor drives the driving gear to rotate, and the driving gear simultaneously drives the first driving rack and the second driving rack to move, the first driving rack and the second driving rack respectively drive the first sliding plate and the second sliding plate to slide on the mounting base plate, and the first sliding plate and the second sliding plate respectively drive the first air guide plate and the second air guide plate to move closer to or away from each other, thereby realizing the closing or opening of the indoor unit air outlet.

[0010] In the optional technical solution of the above-mentioned air conditioner double air guide plate opening and closing mechanism, the output shaft of the driving motor passes through the mounting base plate, and the side surface of the driving motor having the output shaft is fixedly connected to the mounting base plate.

[0011] By adopting the above technical solution, since the output shaft of the driving motor passes through the mounting base plate, the structure in which the driving motor and the mounting base plate are assembled with each other is relatively simple and compact, and the overall size of the driving mechanism can be reduced.

[0012] In the optional technical solution of the above-mentioned double air guide plate opening and closing mechanism of the air conditioner, the driving gear is a helical gear, and the first driving rack and the second driving rack are both helical racks.

[0013] By adopting the above technical scheme, in general, for racks of the same width and gears of the same thickness, helical rack and pinion transmission is more efficient than spur rack and pinion transmission; helical rack transmission is relatively smoother than spur rack transmission; helical racks have a higher contact rate than spur teeth and have more effective contact teeth, thereby improving the load-bearing capacity; the length of the helical rack is an integer and is easier to assemble to the mounting base plate; the helical rack has low operating noise, especially at high speeds; the helical rack and pinion transmission has good operating stability and an accompanying noise reduction effect.

[0014] In the optional technical solution of the above-mentioned air-conditioning double air guide plate opening and closing mechanism, the first sliding plate is provided with a first sliding portion, the second sliding plate is provided with a second sliding portion, the mounting base plate is provided with a first sliding groove and a second sliding groove, the first sliding portion is slidably set in the first sliding groove, and the second sliding portion is slidably set in the second sliding groove.

[0015] By adopting the above technical solution, the first sliding plate realizes sliding connection with the mounting base plate through the sliding cooperation between the first sliding part and the first sliding groove, which is one of the specific structural forms in which the first sliding plate and the mounting base plate are slidably connected to each other. The second sliding plate realizes sliding connection with the mounting base plate through the sliding cooperation between the second sliding part and the second sliding groove, which is one of the specific structural forms in which the second sliding plate and the mounting base plate are slidably connected to each other. This structure has the advantages of simple structure, smooth operation and low manufacturing cost.

[0016] In the optional technical solution of the above-mentioned air-conditioning double air guide plate opening and closing mechanism, the end of the first sliding portion extends beyond the mounting base and is provided with a first anti-slip portion, and the first anti-slip portion is slidably fitted with the mounting base, and the end of the second sliding portion extends beyond the mounting base and is provided with a second anti-slip portion, and the second anti-slip portion is slidably fitted with the mounting base.

[0017] By adopting the above technical solution, the first anti-slip portion can prevent the first sliding portion from detaching from the first sliding groove, thereby realizing a stable sliding connection between the first sliding plate and the mounting base plate; the second anti-slip portion can prevent the second sliding portion from detaching from the second sliding groove, thereby realizing a stable sliding connection between the second sliding plate and the mounting base plate.

[0018] In the optional technical solution of the above-mentioned air conditioner double air guide plate opening and closing mechanism, both ends of the first driving rack are provided with a first limiting portion, and both ends of the second driving rack are provided with a second limiting portion.

[0019] By adopting the above technical solution, the first limiting portion can prevent the driving gear from being disengaged from the first driving rack, so that the driving gear always maintains a stable meshing state with the first driving rack; the second limiting portion can prevent the driving gear from being disengaged from the second driving rack, so that the driving gear always maintains a stable meshing state with the second driving rack.

[0020] In the optional technical solution of the above-mentioned air conditioner double air guide plate opening and closing mechanism, the side surfaces of the first air guide plate and the second air guide plate that are butted against each other are both arranged as inclined surfaces that abut against each other.

[0021] By adopting the above technical solution, because the side surfaces of the first air guide plate and the second air guide plate that are connected to each other are set as inclined surfaces that abut each other, when the indoor unit is closed, the first air guide plate and the second air guide plate can be smoothly fitted together without any gaps.

[0022] In the optional technical solution of the above-mentioned air-conditioning double air guide plate opening and closing mechanism, the driving mechanism includes a linear two-finger electric claw, and the linear two-finger electric claw is arranged on the mounting base plate, and the two claws of the linear two-finger electric claw are respectively connected to the first sliding plate and the second sliding plate.

[0023] By adopting the above technical solution, the two claws of the linear two-finger electric claw directly drive the first sliding plate and the second sliding plate to move away from or closer to each other, thereby realizing the opening or closing of the indoor unit air outlet, further simplifying the structure of the driving mechanism, and the linear two-finger electric claw runs smoothly, efficiently and quietly.

[0024] In a second aspect, an embodiment of the present application provides an air-conditioning indoor unit, comprising the above-mentioned air-conditioning double air guide plate opening and closing mechanism.

[0025] By adopting the above technical solution, the overall driving method of the air guide plate is to use a set of driving mechanisms to simultaneously drive the two air guide plates to move closer to or away from each other. Compared with the related technology, the number of air guide plate driving mechanisms is reduced, the structure of the indoor unit is simplified, and the manufacturing cost of the air conditioner is reduced.

[0042] As mentioned above in the background technology, a wall-mounted air conditioner is a commonly used household air conditioner. A wall-mounted air conditioner is also called a split air conditioner, which includes an indoor unit and an outdoor unit. The indoor unit is usually installed on a indoor wall, and an air guide plate is usually installed at the air outlet of the indoor unit.

[0043] An air outlet of an indoor unit on the market is equipped with two air guide plates. When the air conditioner is turned on, the two air guide plates move horizontally and away from each other to open the air outlet of the indoor unit. When the air conditioner is turned off, the two air guide plates move horizontally and closer to each other until they abut against each other to close the air outlet of the indoor unit.

[0044] Since the two air guide plates are driven by a separate set of driving mechanisms, the structure of the indoor unit is relatively complex and the manufacturing cost of the air conditioner is relatively high.

[0045] Therefore, in order to improve or solve the above-mentioned technical problems, the embodiment of the present application provides an air-conditioning double air guide plate opening and closing mechanism and an air-conditioning indoor unit. In the technical solution provided by the embodiment of the present application, the overall driving method is to use a set of driving mechanisms to simultaneously drive the two air guide plates to move closer to or away from each other. Compared with the related technology, the number of air guide plate driving mechanisms is reduced, the structure of the indoor unit is simplified, and the manufacturing cost of the air conditioner is reduced.

[0046] Reference below Figure 1-Figure 3 The air-conditioning double air guide plate opening and closing mechanism and the air-conditioning indoor unit provided in the embodiments of the present application are described in detail.

Specifically, the second air guide plate 500 can be glued or welded to the second sliding plate 300; the driving mechanism 600 is arranged on the mounting base plate 100, and is used to simultaneously drive the first sliding plate 200 and the second sliding plate 300 to slide closer to or away from each other on the mounting base plate 100.

[0048] Specifically, when the air conditioner is turned on, the driving mechanism 600 simultaneously drives the first sliding plate 200 and the second sliding plate 300 to slide and move away from each other, and the first sliding plate 200 and the second sliding plate 300 respectively drive the first air guide plate 400 and the second air guide plate 500 to move away from each other to open the air outlet of the indoor unit. When the air conditioner is turned off, the driving mechanism 600 simultaneously drives the first sliding plate 200 and the second sliding plate 300 to slide and move closer to each other, and the first sliding plate 200 and the second sliding plate 300 respectively drive the first air guide plate 400 and the second air guide plate 500 to move closer to each other until they are pressed against each other to close the air outlet of the indoor unit. Since the overall driving method is to use a set of driving mechanisms 600 to simultaneously drive two air guide plates to move closer to or away from each other, compared with the related art, the number of air guide plate driving mechanisms 600 is reduced, the structure of the indoor unit is simplified, and the manufacturing cost of the air conditioner is reduced.

[0050] Specifically, the first anti-detachment portion 220 can prevent the first sliding portion 210 from detaching from the first sliding groove 110, thereby realizing a stable sliding connection between the first sliding plate 200 and the mounting base plate 100; the second anti-detachment portion 320 can prevent the second sliding portion 310 from detaching from the second sliding groove 120, thereby realizing a stable sliding connection between the second sliding plate 300 and the mounting base plate 100.

[0051] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments provided in the present application, the driving mechanism 600 includes a driving motor 610, a driving gear 620, a first driving rack 630 and a second driving rack 640.

[0055] Please refer to Figure 1 and Figure 2 In some embodiments provided in the present application, for example, the sides of the first air guide plate 400 and the second air guide plate 500 that are butted against each other are both inclined surfaces that can abut against each other. Specifically, because the sides of the first air guide plate 400 and the second air guide plate 500 that are butted against each other are both configured as inclined surfaces that abut against each other, when the indoor unit is closed, the first air guide plate 400 and the second air guide plate 500 can be smoothly attached together without gaps.
