Description

[0001] The present invention relates to the technical field of air conditioning, and in particular to a double air guide plate assembly and an air conditioning indoor unit. Background Art

[0002] The air guide plate of the indoor unit of the air conditioner is mainly used to control the wind direction. In different working modes such as cooling and heating, the air guide plate of the indoor unit of the air conditioner is in different positions according to the needs. In order to make the air supply direction of the indoor unit of the air conditioner have good wind direction guidance, and taking into account the rotation limit of the air outlet and meeting the needs of different working modes as much as possible, double air guide plates are usually used to close or open the air outlet of the indoor unit of the air conditioner.

[0003] In order to achieve inclined air outlet, horizontal air outlet or vertical air outlet, the existing air conditioner indoor unit with ordinary double air guide plate structure usually adopts two motors to drive each air guide plate to rotate. Although it is also possible to realize simultaneous rotation or individual rotation of the two air guide plates, the driving mechanism corresponding to the motor, such as the gear transmission mechanism, has a relatively complex structure, occupies a large space, and has a relatively high cost, which affects the user experience. In addition, since the distance between the two rotating shafts is relatively close, it is difficult to transmit the force to the rotating air guide plate. Summary of the invention

[0036] Below, the present invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0037] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] like Figures 1 to 5 As shown, the present invention provides a double air guide plate assembly, which includes a first air guide plate 11, a second air guide plate 12, a connecting rod transmission assembly and an intermittent transmission assembly, and the intermittent transmission assembly includes a first rotating shaft and a second rotating shaft.

[0041] Specifically, the first rotating shaft is synchronously connected to the first air guide plate, and the second rotating shaft is synchronously connected to the second air guide plate. The connecting rod transmission assembly is used to guide the first air guide plate to rotate synchronously with the first rotating shaft, and the intermittent transmission assembly is used to guide the second rotating shaft to rotate intermittently or synchronously with the first rotating shaft.

[0042] On the basis of the above structure, when using the above double air guide plate assembly, this embodiment is explained by taking the installation of the double air guide plate assembly at the air outlet of the air conditioner indoor unit as an example, and the double air guide plate can open or close the corresponding air outlet on the air conditioner indoor unit.

[0043] When the driving assembly is just started, the second rotating shaft is in a rest state, the second air guide plate 12 does not rotate, the intermittent transmission assembly first guides the connecting rod transmission assembly to move, and the connecting rod transmission assembly guides the first rotating shaft to rotate at the same time, and the first air guide plate 11 is driven to rotate by the first rotating shaft. When the first air guide plate 11 rotates until the intermittent transmission assembly guides the second rotating shaft to rotate synchronously with the first rotating shaft, the first air guide plate 11 and the second air guide plate 12 maintain the angle formed by the first air guide plate 11 and the second air guide plate 12 at this time and rotate synchronously to achieve the air outlet angle in the double air guide plate state. When the first air guide plate 11 and the second air guide plate 12 are to be restored to the initial state, the intermittent transmission assembly moves in the reverse direction and guides the connecting rod transmission assembly to move in the reverse direction until the second rotating shaft rotates to the rest state, at which time the second air guide plate 12 stops rotating first and returns to the initial state, and the intermittent transmission assembly continues to guide the connecting rod transmission assembly to rotate in the reverse direction until the first air guide plate 11 rotates to the initial state.

[0044] In this embodiment, the intermittent transmission assembly is matched with the connecting rod transmission assembly, and the first rotating shaft of the intermittent transmission assembly is synchronously connected to the first air guide plate 11 through the connecting rod transmission assembly, and the second rotating shaft is synchronously connected to the second air guide plate 12, so as to realize the long-distance motion transmission of the first rotating shaft and the second rotating shaft. Compared with the gear transmission mechanism in the prior art that directly drives the air guide plate to rotate through the rotating shaft transmission coaxial with the gear, the rotation of the first air guide plate 11 is easier. In addition, the second air guide plate 12 and the first air guide plate 11 can realize synchronous rotation or intermittent rotation under the same source drive, that is, the first air guide plate 11 can be rotated first, and after the first air guide plate 11 rotates to the required angle, the second rotating shaft ends the rest state and enters the rotation state. In this way, the two air guide plates can rotate synchronously, and the reverse rotation is the same, which simplifies the cumbersome structure of the existing double air guide plates driven by different sources, reduces the space occupied by the double air guide plate assembly, and improves the user experience while meeting the needs of users for different air outlet angles.

[0045] It can be understood that after the driving assembly is started, the first rotating shaft performs continuous motion, while the second rotating shaft performs intermittent motion.

[0046] Specifically, Figure 1 and Figure 2 As shown, in this embodiment, the above-mentioned connecting rod transmission assembly includes a crank 22 and a connecting rod 21, one end of the crank 22 is synchronously connected to the first rotating shaft, the other end of the crank 22 is rotationally connected to one end of the connecting rod 21, and the other end of the connecting rod 21 is rotationally connected to the first air guide plate 11.

[0047] Based on this, the crank 22, the connecting rod 21, the first air guide plate 11 and the second air guide plate 12 are connected to form a four-bar mechanism, and the vertical distance between the end of the crank 22 connected to the first rotating shaft and the connection between the two air guide plates forms the frame rod of the four-bar mechanism, and the vertical distance between the connection between the connecting rod 21 and the first air guide plate 11 and the connection between the two air guide plates forms the rocker of the four-bar mechanism, so that the four-bar mechanism is a crank rocker mechanism. It can be understood that the four-bar mechanism formed between the crank 22, the connecting rod 21, the first air guide plate 11 and the second air guide plate 12 needs to satisfy the above-mentioned crank 22 and the frame rod The sum is less than or equal to the sum of the remaining two rods can form a crank rocker mechanism, and the active rod is the crank 22 to make the rotation center of the first air guide plate 11 The rotation connection of the two air guide plates, the crank 22 and the connecting rod 21 can rotate smoothly, thereby realizing the state from the state where only the first air guide plate 11 rotates to the state where the two air guide plates rotate synchronously.

[0048] Specifically, the second rotating shaft stops stopping and enters the rotating state after the first air guide plate 11 rotates to form an extension plate with the second air guide plate 12, as shown in FIG. Figure 1 As shown, in this embodiment, the first air guide plate 11 and the second air guide plate 12 are vertically arranged in an initial state, the first air guide plate 11 is arranged on a vertical plane, and the second air guide plate 12 is arranged on a horizontal plane.

[0049] On the basis of the above structure, when the intermittent transmission component is started, the second rotating shaft is in a dormant state, and the second air guide plate 12 does not rotate. The intermittent transmission component first guides the first rotating shaft to rotate. Since one end of the crank 22 is synchronously connected to the first rotating shaft, the other end of the crank 22 is connected to one end of the connecting rod 21, and the other end of the connecting rod 21 is rotationally connected to the first air guide plate 11. When the first rotating shaft rotates, the end of the crank 22 connected to the connecting rod 21 rotates around the first rotating shaft. At this time, the other end of the connecting rod 21 swings around the rotating connection between the two air guide plates, and at the same time pushes the first air guide plate 11 to rotate. When the first air guide plate 11 rotates to the extension plate of the second air guide plate 12, the intermittent transmission component starts to guide the second rotating shaft to rotate. Thereafter, the intermittent transmission component guides the first rotating shaft and the second rotating shaft to rotate simultaneously, and the second air guide plate 12 and the first air guide plate 11 rotate synchronously as if they are extension plates of each other.

[0050] If the two air guide plates are to close the air outlet when the air conditioner is turned off, that is, the first air guide plate 11 and the second air guide plate 12 are restored to the initial mutually perpendicular state, if the rotation direction of the first air guide plate 11 and the second air guide plate 12 is clockwise, then when the air conditioner is turned off, the intermittent drive component guides the first air guide plate 11 and the second air guide plate 12 to rotate counterclockwise. Taking the state where the first air guide plate 11 and the second air guide plate 12 are parallel to the vertical direction at this time as an example, during the counterclockwise rotation of the first air guide plate 11 and the second air guide plate 12 as mutually extended plates, the first air guide plate 11 and the second air guide plate 12 first rotate to be parallel to the horizontal direction, and then continue to rotate counterclockwise, the second rotation axis has returned to the dormant motion state, then only the first air guide plate 11 continues to rotate until the first air guide plate 11 rotates to close the air outlet.

[0051] In this embodiment, the crank rocker mechanism is used to guide the first air guide plate 11 to rotate, and the structure is simple and easy to implement. It should be noted that the connecting rod assembly can also be connected with the first air guide plate 11 and the second air guide plate 12 to form other four-bar mechanisms or multi-bar mechanisms, as long as the first air guide plate 11 can smoothly perform reciprocating rotation on both sides of the two air guide plates that are mutually extended plates, and the active rod can also select a suitable rotation angle according to the requirements of the air outlet angle.

[0052] Furthermore, the intermittent transmission assembly of this embodiment includes a driving member and a driven member, and the driving member can be staggered or rotated synchronously with the driven member, that is, when the driving member and the driven member are in a non-contact state, the driven member stops, and when the driving member and the driven member are in contact, the driving member drives the driven member to rotate synchronously. The intermittent transmission assembly also includes a first gear 31, and the first gear 31 is arranged on the first rotating shaft. The driving member and the first gear 31 are always in a meshing connection state, and the driven member is synchronously connected with the second rotating shaft.

[0053] On the basis of the above structure, when the intermittent transmission assembly is started, the active member guides the first gear 31 to drive the first rotating shaft to rotate. Since the active member rotates continuously and the first gear 31 is always synchronously connected with the active member, the first gear 31 also rotates continuously. The crank 22 drives the connecting rod 21 to rotate under the continuous rotation of the first gear 31, and the connecting rod 21 drives the first air guide plate 11 to rotate. Since the driven member is staggered or rotates synchronously with the active member, the driven member is synchronously connected with the second rotating shaft. Therefore, when the driven member is staggered with the active member, the second rotating shaft stops and the second air guide plate 12 does not rotate. When the driven member rotates synchronously with the active member, the second rotating shaft also rotates synchronously, so that the second air guide plate 12 and the first air guide plate 11 rotate synchronously.

[0054] The active member of the intermittent transmission assembly of the present embodiment is synchronously connected with the first gear 31, so that the driven member and the first gear 31 respectively guide the second air guide plate 12 and the first air guide plate 11 to rotate, and because the first gear 31 always rotates when the intermittent transmission assembly is started, the driven member rotates intermittently, so that the first air guide plate 11 rotates continuously within one rotation cycle of the active member, and when the driven member rotates later, the first air guide plate 11 and the second air guide plate 12 rotate synchronously, and the structure is simple and easy to implement.

[0055] like Figure 2 As shown, the active member may be the third gear 33, and the driven member may be the second gear 32, and the second gear 32 is disposed on the second rotating shaft. Specifically, the third gear 33 is axially provided with a first transmission section 331 and a second transmission section, the first transmission section 331 is meshedly connected with the first gear 31, and the second transmission section is rollingly matched or meshedly connected with the second gear 32.

[0056] On the basis of the above structure, when the intermittent transmission component is started, the third gear 33 rotates continuously. Since the first gear 31 is always meshed with the first transmission section 331 on the third gear 33, the first gear 31 rotates continuously. At the same time, if the second gear 32 is rollingly connected to the second transmission section, the second gear 32 does not rotate, and the second rotating shaft does not rotate, so the second air guide plate 12 does not rotate. If the second gear 32 is meshed with the second transmission section, the second gear 32 is meshed with the third gear 33 and rotates, and the second air guide plate 12 rotates simultaneously driven by the second rotating shaft, thereby realizing the simultaneous rotation of the first air guide plate 11 and the second air guide plate 12.

[0057] Specifically, the second transmission section is provided with a toothless section 3322 and a meshing section 3321 in the rotation direction. The toothless section 3322 can be rollingly connected with the second gear 32, and the meshing section 3321 is meshingly connected with the second gear 32.

[0058] Based on the above structure, when the intermittent transmission assembly is started, the third gear 33 rotates. When the first air guide plate 11 rotates to be parallel to the horizontal plane, since the first gear 31 is meshed with the first transmission section 331 of the third gear 33, the first gear 31 and the third gear 33 rotate simultaneously. The specific rotation state can be that the third gear 33 rotates counterclockwise, while the first gear 31 rotates clockwise. At the same time, since the second gear 32 is firstly connected with the toothless section 3322 of the third gear 33 by rolling, the second rotating shaft is in a rest state at this time, and the second air guide plate 12 does not rotate.

[0059] The first rotating shaft is synchronously connected to the first gear 31, so at this time, the first rotating shaft and the first gear 31 rotate synchronously clockwise. Since one end of the crank 22 is synchronously connected to the first rotating shaft, the other end of the crank 22 is connected to one end of the connecting rod 21, and the other end of the connecting rod 21 is rotationally connected to the first air guide plate 11, then when the first rotating shaft rotates clockwise, the end of the crank 22 connected to the connecting rod 21 rotates clockwise around the first rotating shaft. At this time, the other end of the connecting rod 21 rotates clockwise around the axis of the rotation connection of the two air guide plates, that is, the first air guide plate 11 rotates clockwise around the axis of the rotation connection of the two air guide plates, until the first air guide plate 11 rotates clockwise to be parallel to the horizontal plane, so that the first air guide plate 11 and the second air guide plate 12 are extended plates of each other on the horizontal plane. At this time, the air-conditioning wind is discharged in the horizontal direction under the guidance of the first air guide plate 11 and the second air guide plate 12.

[0060] When the first air guide plate 11 rotates clockwise to the extension plate of the second air guide plate 12, the second gear 32 is about to engage with the meshing section 3321. When the first air guide plate 11 and the second air guide plate 12 continue to rotate clockwise as an extension of each other, the second gear 32 engages with the meshing section 3321. The second gear 32 begins to rotate clockwise under the counterclockwise rotation of the third gear 33, and the second rotating shaft synchronously connected to the second gear 32 also begins to rotate clockwise. Thereafter, the intermittent transmission component guides the first rotating shaft and the second rotating shaft to rotate clockwise at the same time, thereby realizing the synchronous clockwise rotation of the second air guide plate 12 and the first air guide plate 11 as extensions of each other. When the second air guide plate 12 and the first air guide plate 11 rotate to be parallel to the vertical plane as extensions of each other, the air-conditioning wind is discharged in the vertical direction.

[0061] When the first air guide plate 11 and the second air guide plate 12 rotate synchronously to be parallel to the vertical plane in the posture of mutually extending plates, the meshing section 3321 of the second gear 32 and the third gear 33 is about to be staggered. At this time, the driving component drives the linkage mechanism to start to reversely guide the first rotating shaft and the second rotating shaft to rotate, and the third gear 33 starts to rotate clockwise. Then the second gear 32 meshes with the meshing section 3321 of the third gear again in a counterclockwise manner, and the second rotating shaft synchronously connected to the second gear 32 also rotates counterclockwise. Since the second air guide plate 12 is synchronously connected to the second rotating shaft, the second air guide plate 12 also rotates counterclockwise. At the same time, the first gear 31, which is always meshed with the third gear 33, also rotates counterclockwise, and the first rotating shaft synchronously connected to the first gear 31 also rotates counterclockwise. The counterclockwise rotating first rotating shaft drives the crank 22 to connect one end of the connecting rod 21 to rotate counterclockwise around the first rotating shaft. Driven by the crank 22, the connecting rod 21 also swings counterclockwise as a whole. At the same time, the connecting rod 21 drives the first air guide plate 11 to rotate counterclockwise, thereby realizing the counterclockwise rotation of the first air guide plate 11 and the second air guide plate 12 as extensions of each other, until the first air guide plate 11 and the second air guide plate 12 rotate in the opposite direction as extensions of each other and return to being parallel to the horizontal plane.

[0062] When the first air guide plate 11 and the second air guide plate 12 rotate counterclockwise in a posture of extending each other until they are both parallel to the horizontal plane, the second gear 32 is about to disengage from the meshing connection with the meshing section 3321 and begin to roll with the toothless section 3322. At this time, the second gear 32 stops rotating, and the second air guide plate 12 also stops rotating, and the second air guide plate 12 returns to its initial state of being parallel to the horizontal plane.

[0063] The first gear 31 is always meshed with the first meshing section 331, so the first gear 31 drives the first rotating shaft to rotate counterclockwise at this time, and the crank 22 synchronously connected to the first rotating shaft is connected to one end of the connecting rod 21 to rotate counterclockwise around the first rotating shaft, and the connecting rod 21 also swings counterclockwise as a whole under the counterclockwise drive of the crank 22. At the same time, the first air guide plate 11 rotates counterclockwise around the axis of the connection between the two air guide plates under the drive of the connecting rod 21 until the first air guide plate 11 rotates to be parallel to the vertical plane, so that the first air guide plate 11 and the second air guide plate 12 return to their initial perpendicular state.

[0064] The intermittent motion device of the present embodiment specifically adopts an incomplete gear mechanism. While realizing the intermittent rotation of the second rotating shaft, the incomplete gear mechanism realizes that the first air guide plate 11 always rotates when the driving component is started by always meshing and connecting the driving wheel of the incomplete gear mechanism with the first gear. When the second rotating shaft meshes and rotates with the driven wheel, the second air guide plate 12 and the first air guide plate 11 can rotate synchronously. The structure is simple and easy to realize.

[0065] It should be noted that, in other embodiments, the intermittent transmission assembly of the third gear 33 and the second gear 32 may also be a clutch mechanism, etc., as long as it can maintain meshing connection with the first gear 31 at the corresponding position on the active member during the rotation cycle. Of course, the first gear 31 may also be replaced by other structures in the prior art, as long as it can maintain synchronous rotation with the active member, and a reasonable combination can be selected according to the actual structural conditions.

[0066] In this embodiment, the first gear 31 and the second gear 32 are coaxially arranged, that is, the first gear 31 and the second gear 32 can rotate around the same rotation center axis, and the first gear 31 is arranged between the second gear 32 and the first air guide plate 11. Such a design makes the structure of the intermittent transmission component more reasonable and further reduces the occupied space.

[0067] Furthermore, the connection structure between the first rotating shaft and the crank 22 is specifically as follows: Figure 3 As shown, a clamping portion 311 is provided at one end of the first rotating shaft away from the second gear 32, and a clamping groove 310 adapted thereto is provided at a position corresponding to the clamping portion 311 on the crank 22, which can specifically be a clamping fit between a polygonal prism structure and a polygonal groove.

[0068] Thus, when the first gear 31 rotates, the first rotating shaft and the first air guide plate 11 are synchronously connected because the clamping portion 311 on the first gear 31 is clamped and matched with the clamping groove 310 on the crank 22. The connection structure between the first gear 31 and the crank 22 of this embodiment is realized by clamping and matching, and the structure is simple and easy to realize. The synchronous connection structure between the second rotating shaft and the second air guide plate 12 is similar, and will not be described in detail here.

[0069] Furthermore, if Figure 2 As shown, the intermittent transmission assembly also includes a motor 4, which has an output shaft. A pressure cover 41 is provided on the side of the motor 4 facing the output shaft. The third gear 33 and the second gear 32 are provided on the same side of the pressure cover 41, and the third gear 33 is fixedly connected to the output shaft. A positioning shaft is provided on the pressure cover 41 at a position corresponding to the second gear 32, and the second gear 32 is rotatably mounted on the positioning shaft. The second rotating shaft passes through the center hole of the first gear 31 and is fixedly connected to the second air guide plate 12.

[0070] In this way, after the motor 4 is started, the output shaft rotates and drives the third gear 33 to rotate. The specific movement process of the intermittent transmission component has two stages. In the first stage, the second gear 32 rolls with the toothless section 3322 of the third gear 33, the second gear 32 does not rotate, and the second rotating shaft does not rotate. The first gear 31 is meshed with the first transmission section 331 of the third gear 33, and the first gear 31 rotates synchronously with the third gear 33 in opposite directions. In the second stage, the second gear 32 is meshed with the meshing section 3321 of the third gear 33, and the second gear 32 rotates synchronously with the third gear 33 in opposite directions. At this time, the second gear 32 has the same rotation direction as the first gear 31. When the motor 4 drives the first rotating shaft to reverse, the specific movement process of the intermittent transmission component is the same, which will not be repeated here. It should be noted that the motor 4 can select a motor with a suitable structure in the prior art.

[0071] like Figure 4 As shown, further, the relative rotation structure of the first air guide plate 11 and the second air guide plate 12 can be that two swivel seats 51 are provided on the second air guide plate 12, and an installation groove 50 is opened at the position of the first air guide plate 11 corresponding to the swivel seat 51, and the swivel seat 51 can be rotatably installed in the installation groove 50, thereby realizing the relative rotation of the first air guide plate 11 and the second air guide plate 12.

[0072] Specifically, the first air guide plate 11 and the rotating seat 51 can be connected to each other by opening an axial hole on the rotating seat 51 and passing through the rotating seat 51, and setting a rotating shaft on the mounting slot 50 at a position corresponding to the axial hole, and the rotating shaft can be rotatably matched with the axial hole, so that the first air guide plate 11 can rotate relative to the second air guide plate 12 by rotating the rotating shaft with one end of the axial hole of the rotating seat 12. It should be noted that the rotating shaft can also be set at both ends of the rotating seat 51, and the axial holes can be correspondingly opened on the first air guide plate 11 and the second air guide plate 12, as long as the two air guide plates can rotate relative to each other.

[0073] like Figure 5 As shown, the present application also provides an air-conditioning indoor unit, including an air-conditioning host 1 and the above-mentioned double air guide plate assembly, the air-conditioning host 1 is provided with a first air outlet surface 111 and a second air outlet surface 121, the first air outlet surface 111 intersects with the second air outlet surface 121, the first air outlet surface 111 is provided with a first air outlet, the second air outlet surface 121 is provided with a second air outlet, the first air guide plate 11 is used to open or close the first air outlet, and the second air guide plate 12 is used to open or close the second air outlet.

[0074] Specifically, in this embodiment, the first air outlet surface 111 is parallel to the vertical plane, and the second air outlet surface 121 is parallel to the horizontal plane. Then:

[0075] When the cooling mode is needed, since the cold air condenses downward, adjusting the cold wind direction to a horizontal direction is more conducive to indoor air circulation. Therefore, if you want to achieve rapid cooling, you only need to start the driving component to guide the first air guide plate 11 to an extension plate of the second air guide plate 12. At this time, the cold air is guided by the first air guide plate 11 and the second air guide plate 12 to flow in a horizontal direction, and then settles downward to achieve rapid cooling.

[0076] When the heating mode is needed, since the hot air condenses upward, adjusting the hot air direction to a vertically downward direction is more conducive to indoor air circulation. Therefore, if you want to heat quickly, you need to drive the component to guide the first air guide plate 11 and the second air guide plate 12 to rotate synchronously to be parallel to the vertical plane. At this time, the hot air is guided by the first air guide plate 11 and the second air guide plate 12 to flow vertically downward, and then floats upward to achieve rapid heating.

[0077] The air supply paths of the above two air outlet modes are formed by two air guide plates that extend each other, which have the best air supply effect and can achieve rapid temperature change. Of course, the above two modes are only rapid temperature change modes. If you want to achieve inclined air outlet, you can stop driving the drive component when the double air guide plates rotate to the required inclined air outlet angle.

[0078] It should be noted that, for the reciprocating swing of the inclined air outlet effect, the intermittent rotation cycle can be designed according to the air outlet angle requirements in this embodiment.

[0079] This embodiment adopts the above-mentioned double air guide plate assembly, so that the first rotating shaft and the second rotating shaft which are synchronously connected to the first air guide plate 11 and the second air guide plate 12 respectively can realize the synchronous rotation or intermittent rotation of the second air guide plate 12 and the first air guide plate 11 under the cooperation of the intermittent transmission assembly and the connecting rod transmission assembly, thereby simplifying the overall structure, optimizing the air supply effect, and better meeting the needs of users.
