Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning equipment, and in particular to an air guide door assembly and an air conditioner. Background Art

[0002] In the current cabinet air-conditioning structure, since the appearance of the external air guide door is usually designed in an arc shape, there must be an angle difference when the left and right air guide doors are placed at the corresponding left and right positions of the air outlet frame, which causes the corresponding air guide door cranks to also have an angle difference.

[0003] The existing air conditioner sets the crank-connecting rod mechanism as a parallelogram mechanism to avoid the problem of unstable air guide door caused by the above situation. However, the left and right air guide doors need to be designed so that they can only be installed on the left and right air guide door cranks, which is not convenient for distinguishing and installing the left and right air guide doors. Of course, if the crank-connecting rod mechanism of the air conditioner is set as a non-parallelogram mechanism, a universal air guide door and crank can be designed, which can save molds and facilitate installation. However, the non-parallelogram has problems such as small opening and closing degree, dead points at the leftmost and rightmost extreme positions, and the angular velocity of the crank is not constant during the movement of the air guide door, which causes the angular velocity of the crank to continue to change during the movement, thereby causing unstable movement of the air guide door.

DETAILED DESCRIPTION

[0043] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0044] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0045] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0046] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the utility model product is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0047] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0048] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0049] In the current cabinet air-conditioning structure, since the appearance of the external air guide door is usually designed in an arc shape, there must be an angle difference when the left and right air guide doors are placed at the corresponding left and right positions of the air outlet frame, which causes the corresponding air guide door cranks to also have an angle difference.

[0050] The existing air conditioner sets the crank-connecting rod mechanism as a parallelogram mechanism to avoid the problem of unstable air guide door caused by the above situation. However, the left and right air guide doors need to be designed so that they can only be installed on the left and right air guide door cranks, which is not convenient for distinguishing and installing the left and right air guide doors. Of course, if the crank-connecting rod mechanism of the air conditioner is set as a non-parallelogram mechanism, a universal air guide door and crank can be designed, which can save molds and facilitate installation. However, the non-parallelogram has problems such as small opening and closing degree, dead points at the leftmost and rightmost extreme positions, and the angular velocity of the crank is not constant during the movement of the air guide door, which causes the angular velocity of the crank to continue to change during the movement, thereby causing unstable movement of the air guide door.

[0051] Based on the above problems, an embodiment of the present invention provides an air conditioner 10, which can not only set the crank-connecting rod 200 mechanism as a parallelogram mechanism, but also realize the universal use of the left and right air guide doors 400 and the left and right air guide door cranks 300, thereby ensuring the stable movement of the crank-connecting rod 200 mechanism while realizing the universal use of the left and right air guide doors 400 and the air guide door cranks 300.

[0052] See also Figure 1 The air conditioner 10 includes an indoor unit and an outdoor unit, wherein the indoor unit includes a shell 12 and an air guide door assembly 11, the air guide door assembly 11 is arranged on the shell 12, the shell 12 is provided with an air outlet 13, and the air guide door 400 corresponds to the air outlet 13 and is used to open or close the air outlet 13.

[0053] Optionally, the indoor unit may be a vertical cabinet unit.

[0054] For further information, please refer to Figures 2 to 8 The air guide door assembly 11 includes an air outlet frame 100, a connecting rod 200, an air guide door crank 300, and an air guide door 400. The number of the air guide door crank 300 and the number of the air guide door 400 are the same and can be multiple. The multiple air guide doors 400 are arranged on the multiple air guide door cranks 300 in a one-to-one correspondence.

[0055] Among them, the air outlet frame 100 is provided with a first mounting hole 110 and a second mounting hole 120. The first mounting hole 110 is provided on the left side of the air outlet frame 100, and the second mounting hole 120 is provided on the right side of the air outlet frame 100. Therefore, the first mounting hole 110 is used to install the left air guide door 400, and the second mounting hole 120 is used to install the right air guide door 400.

[0056] The connecting rod 200 is arranged on the air outlet frame 100 and is used to connect with the driving member 500; the air guide door crank 300 includes a connecting portion 310 and a rotating shaft portion 320, one end of the connecting portion 310 is connected to the connecting rod 200, and the other end is connected to the rotating shaft portion 320, the rotating shaft portion 320 is rotatably arranged in the first mounting hole 110 or the second mounting hole 120, and the rotating shaft portion 320 is provided with a clamping portion 330; the air guide door 400 is provided with a first clamping portion 410 and a second clamping portion 420.

[0057] It can be understood that during actual operation, the driving member 500 drives the connecting rod 200 to move, thereby driving the air guide door crank 300 connected to the connecting rod 200 to move, and the air guide door crank 300 drives the air guide door 400 to rotate, thereby realizing that the air guide door 400 opens or closes the air outlet 13.

[0058] In this embodiment, the connecting rod 200, the air guide door crank 300 provided in the first mounting hole 110, the air guide door crank 300 provided in the second mounting hole 120, and the connecting line of the first mounting hole 110 and the second mounting hole 120 together form a parallelogram profile (such as Figure 3 dotted line).

[0059] Therefore, the connecting rod 200 and the two air guide door cranks 300 provided in the first mounting hole 110 and the second mounting hole 120 are set to form a parallelogram crank-connecting rod 200 mechanism, so that the angular velocity of the rotating shaft portion 320 of the air guide door crank 300 is constant during rotation, thereby making the movement of the air guide door 400 more stable and having a sufficient opening and closing degree; and when the rotating shaft portion 320 is provided in the first mounting hole 110, the clamping portion 330 is clamped with the first clamping portion 410; when the rotating shaft portion 320 is provided in the second mounting hole 120, the clamping portion 330 is clamped with the second clamping portion 420, thereby realizing the air guide door When 400 is set on the left side of the air outlet frame 100 as the left air guide door 400, the air guide door 400 can be installed and fixed by clamping the clamping part 330 and the first clamping part 410. When the air guide door 400 is installed on the right side of the air outlet frame 100 as the right air guide door 400, the air guide door 400 can be installed and fixed by clamping the clamping part 330 and the second clamping part 420. In this way, the commonality of the left and right air guide doors 400 and the left and right air guide door cranks 300 is achieved, which not only saves mold opening costs, but also simplifies object management, and makes it convenient to distinguish and install the left and right air guide doors 400 and the left and right air guide door cranks 300 during the installation process.

[0060] It should also be noted that the air outlet frame 100 may further be provided with a third mounting hole...an nth mounting hole, and so on, where n is the number of mounting holes provided on the air outlet frame 100 , and n is greater than or equal to 3.

[0061] For example, when the number of mounting holes is at least three, the number of air guide doors 400 is also n, and every two adjacent air guide door cranks 300 and connecting rods 200 form a parallelogram mechanism; in addition, the air guide door 400 is provided with a third clamping portion...an nth clamping portion; therefore, when the air guide door 400 is set in the third mounting hole, the air guide door 400 can be installed and fixed at the third mounting hole by clamping the clamping portion 330 with the third clamping portion, and the air guide door 400 can be installed and fixed at the fourth mounting hole by clamping the clamping portion 330 with the fourth clamping portion. Similarly, the air guide door 400 can be installed and fixed at the nth mounting hole by clamping the clamping portion 330 with the nth clamping portion.

[0062] Furthermore, the air guide door 400 is also provided with a first marking portion 430 and a second marking portion 440, the first marking portion 430 is adjacent to the first clamping portion 410, and the second marking portion 440 is adjacent to the second clamping portion 420, the first marking portion 430 is used to correspond to the first mounting hole 110, and the second marking portion 440 is used to correspond to the second mounting hole 120.

[0063] In this embodiment, a first marking portion 430 is provided near the first clamping portion 410, and a second marking portion 440 is provided near the second clamping portion 420. The first marking portion 430 corresponds to the first mounting hole 110, and the second marking portion 440 corresponds to the second mounting hole 120, thereby facilitating assembly and differentiation. This facilitates the operator to clamp the first clamping portion 410 of the air guide door 400 to the clamping portion 330 of the air guide door crank 300 when installing the air guide door 400 in the first mounting hole 110, and to clamp the second clamping portion 420 of the air guide door 400 to the clamping portion of the air guide door crank 300 when installing the air guide door 400 in the second mounting hole 120. Therefore, installation efficiency is effectively improved.

[0064] Alternatively, the first marking portion 430 may be the text "left," and the second marking portion 440 may be the text "right." If there are multiple mounting holes, a third marking portion, ..., and an nth marking portion may also be provided. In this case, the marking portions may also be numbers, letters, or other marking types, which are not specifically limited herein.

[0065] Furthermore, each air guide door crank 300 has a plurality of clamping parts 330, and each air guide door 400 is provided with a plurality of first clamping parts 410 and a plurality of second clamping parts 420. The plurality of clamping parts 330 are arranged in a one-to-one correspondence with the plurality of first clamping parts 410, or the plurality of clamping parts 330 are arranged in a one-to-one correspondence with the plurality of second clamping parts 420.

[0066] In this embodiment, multiple clamping portions 330 are clamped one-to-one with multiple first clamping portions 410, or multiple clamping portions 330 are clamped one-to-one with multiple second clamping portions 420 to further improve the stability of the air guide door 400 when it is installed on the air guide door crank 300.

[0067] Optionally, there are two clamping portions 330, and the line connecting the two clamping portions 330 is located on the axis of the rotating shaft portion 320, that is, the two clamping portions 330 are distributed 180 degrees. Since the first clamping portion 410 and the second clamping portion 420 match the clamping portion 330, the number of first clamping portions 410 and the number of second clamping portions 420 are also two, and the line on which the two first clamping portions 410 are located is arranged at an angle to the line on which the two second clamping portions 420 are located. Therefore, during installation, the air guide door crank 300 only needs to be rotated a certain angle to cause the clamping portion 330 to engage with the first clamping portion 410 or the second clamping portion 420.

[0068] Furthermore, the holding portion 330 is a rib protruding from the rotating shaft portion 320 , and the first clamping portion 410 and the second clamping portion 420 are both clamping grooves provided on the air guide door 400 .

[0069] In this embodiment, by setting the holding portion 330 as a rib and the first clamping portion 410 as a slot, the rib can be embedded in the slot, so that the holding portion 330 can be clamped with the first clamping portion 410, or the holding portion 330 can be clamped with the second clamping portion 420, thereby achieving the installation and fixation of the air guide door 400 on the air guide door crank 300.

[0070] Of course, in other embodiments of the present application, the clamping portion 330 may also be a clamping groove arranged on the rotating shaft portion 320, and the first clamping portion 410 and the second clamping portion 420 are both ribs protruding from the air guide door 400. As long as the clamping portion 330 can be clamped with the first clamping portion 410, or the clamping portion 330 can be clamped with the second clamping portion 420, no specific limitation is made here.

[0071] Furthermore, the air guide door 400 is provided with a shaft hole 450 , the shaft portion 320 is provided in the shaft hole 450 , and the first clamping portion 410 and the second clamping portion 420 are both provided at the edge of the shaft hole 450 .

[0072] In this embodiment, in the installed state, the shaft portion 320 is passed through the shaft hole 450, and the first clamping portion 410 and the second clamping portion 420 are clamping grooves arranged at the edge of the shaft hole 450, so that the clamping portion 330 arranged on the shaft portion 320 is clamped with the first clamping portion 410 or the second clamping portion 420 while the shaft portion 320 is passed through the shaft hole 450.

[0073] Among them, the center line connecting the first clamping portion 410 and the rotating shaft hole 450 and the center line connecting the second clamping portion 420 and the rotating shaft hole 450 are set at an angle, and the angle between two adjacent clamping portions is 10°~15°. As shown in the figure, the angle between the first clamping portion 410 and the second clamping portion 420 is 10°~15°; and when there are multiple clamping portions, the maximum sum of the angles of the multiple clamping portions is 170°.

[0074] It can be understood that when there are multiple air guide doors 400, multiple clamping parts will also be provided accordingly. Usually, the angle between two adjacent clamping parts and the center line of the rotating shaft hole 450 is 10°~15°. When the total angle of multiple clamping parts is 170°, the angle between two adjacent clamping parts is 10°. In this case, the number of air guide doors is 17, and the number of clamping parts is also 17 (i.e., including the first clamping part, the second clamping part...the seventeenth clamping part).

[0075] Furthermore, the connecting rod 200 includes a first section 210 and a second section 220 connected at an angle, and the second section 220 is used to connect with the driving member 500;

[0076] There are two air guide door cranks 300, and the two rotating shaft parts 320 are rotatably arranged in the first mounting hole 110 and the second mounting hole 120 respectively. The two connecting parts 310 are both connected to the first section 210, and the outline of the plane where the two connecting parts 310 and the connecting rod 200 are located is a parallelogram.

[0077] In this embodiment, the connecting portion 310 of the two air guide door cranks 300 and the first section 210 of the connecting rod 200 form a parallelogram structure, so that the connecting rod 200 and the air guide door crank 300 can move stably and have a larger opening and closing angle, and the angular velocity of the rotating shaft portion 320 is constant during rotation.

[0078] Furthermore, the air guide door assembly 11 also includes a driving member 500, which includes a motor 510 and a motor crank 520 arranged on the air outlet frame 100.
