Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly relates to an air direction adjusting assembly of an air conditioner and an indoor unit having the same. Background Art

[0002] The indoor unit of an air conditioner is generally installed on the ceiling. In order to maintain a flat and smooth appearance, the air outlet is generally blocked by an air direction plate when the operation is stopped. When in the operating state, the air direction plate is exposed outside the housing of the air conditioner to open the air outlet, so that the air conditioner blows air downward. However, since the opening area of the air direction plate is small, the ventilation resistance at the air outlet of the air conditioner is large, resulting in poor air outlet effect and it is difficult to achieve the desired air outlet effect.

[0003] If multiple air direction plates are provided to increase the opening area of the air direction plates, a driving motor needs to be provided for each air direction plate to drive its rotation, which results in high cost and great difficulty in layout.

[0004] Therefore, the air direction plates of the air conditioners in the prior art have problems such as small opening area, large ventilation resistance, poor air outlet effect, and when multiple air direction plates are provided, there are a large number of driving motors, resulting in high cost. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the prior art that the air outlet effect of the air conditioner is poor and when multiple air direction plates are provided, there are a large number of driving motors.

[0006] To solve the above problems, an embodiment of the present invention discloses a wind direction adjustment assembly for an air conditioner, including: a base fixedly disposed inside a first ventilation opening of an indoor unit of the air conditioner; a movable assembly including a main wind direction control plate, an auxiliary wind direction control plate, a main connecting member, and an auxiliary connecting member; and a driving member; wherein one end of the main connecting member is fixedly connected to the main wind direction control plate, and the other end is pivotally disposed on the base through a first rotating shaft; one end of the auxiliary connecting member is fixedly connected to the auxiliary wind direction control plate, and the other end is pivotally disposed on the base through a second rotating shaft; the ends of the main connecting member and the auxiliary connecting member close to the base are pivotally connected together through a third rotating shaft; the second rotating shaft and the third rotating shaft are both disposed in a guiding track on the base; the driving member is connected to the main connecting member to drive the main connecting member to rotate relative to the base around the first rotating shaft; and when the driving member drives the main connecting member in a first direction, the main connecting member is driven to rotate around the first rotating shaft, and through the third rotating shaft, the auxiliary connecting member is driven to rotate around the second rotating shaft, so as to drive the main wind direction control plate and the auxiliary wind direction control plate to move from a closed state to a first open state where the first ventilation opening is exposed; with the continuous driving of the driving member, the main connecting member drives the second rotating shaft and the third rotating shaft to move along the guiding track through the third rotating shaft, so as to drive the main wind direction control plate and the auxiliary wind direction control plate to move from the first open state to a second open state where they are inclined downward relative to the first ventilation opening.

[0007] With the above solution, by providing two wind direction control plates such as the main wind direction control plate and the auxiliary wind direction control plate, the opening area of the wind direction control plate of the indoor unit of the air conditioner can be increased, thereby reducing the ventilation resistance and improving the ventilation effect. Moreover, the main connecting member that drives the main wind direction control plate to rotate and the auxiliary connecting member that drives the auxiliary wind direction control plate to rotate are arranged in a pivotable manner through the third rotating shaft. Only one driving member needs to be provided for the main connecting member to drive the auxiliary connecting member to drive the auxiliary wind direction control plate to rotate, without separately providing driving members for the main connecting member and the auxiliary connecting member, saving the layout cost and reducing the layout difficulty. In addition, since the second rotating shaft and the third rotating shaft can move in the guiding track, when the driving member drives the main connecting member, the end of the auxiliary connecting member can also be driven to move relative to the base, so that the air outlet direction restricted by the main wind direction control plate and the auxiliary wind direction control plate can be adjusted, enabling the indoor unit to blow air towards the ground or a specific direction, further improving the ventilation effect.

[0008] According to another specific embodiment of the present invention, for the air direction adjusting assembly of the air conditioner disclosed in the embodiment of the present invention, the opening direction of the first air vent is in the horizontal direction, and the main air direction control plate is located below the auxiliary air direction control plate; and, in the extending direction of the main connecting member, the first rotating shaft is closer to one end of the main connecting member than the third rotating shaft, and in the extending direction of the auxiliary connecting member, the third rotating shaft is closer to one end of the auxiliary connecting member than the second rotating shaft; wherein, when looking along the axial direction of the first rotating shaft, when the main air direction control plate and the auxiliary air direction control plate are in the closed state, the first rotating shaft, the second rotating shaft and the third rotating shaft are arranged obliquely with respect to the first air vent, wherein, in the vertical direction, the third rotating shaft is located between the first rotating shaft and the second rotating shaft, and the first rotating shaft is closer to the outer side of the first air vent than the second rotating shaft; when looking along the axial direction of the first rotating shaft, when the main air direction control plate and the auxiliary air direction control plate are in the first open state, the first rotating shaft, the second rotating shaft and the third rotating shaft are arranged in a triangle, wherein, in the vertical direction, the second rotating shaft is located between the first rotating shaft and the third rotating shaft, and the first rotating shaft and the third rotating shaft are closer to the outer side of the first air vent than the second rotating shaft; and, when looking along the axial direction of the first rotating shaft, when the main air direction control plate and the auxiliary air direction control plate are in the second open state, the first rotating shaft, the second rotating shaft and the third rotating shaft are arranged in a triangle, wherein, in the vertical direction, the first rotating shaft is located lower than the second rotating shaft and the third rotating shaft, and the third rotating shaft is closer to the outer side of the first air vent than the first rotating shaft and the second rotating shaft.

[0009] With the above solution, the third rotating shaft is used to connect the main connecting member and the auxiliary connecting member together, so as to realize that only driving the main connecting member can drive the auxiliary connecting member to rotate, and the movement of the second rotating shaft and the third rotating shaft in the guiding track drives the change of the air outlet direction formed by the main air direction control plate and the auxiliary air direction control plate. Only corresponding rotating shafts are arranged within the spatial range of the original main connecting member and auxiliary connecting member, and guiding tracks for the rotating shafts to move are arranged on the base, without occupying extra space, which is beneficial to reducing the volume of the air conditioner.

[0010] According to another specific embodiment of the present invention, for the air direction adjusting assembly of the air conditioner disclosed in the embodiment of the present invention, the base includes a fixing component and at least two supporting components; wherein, the fixing component is fixedly arranged inside the first air vent and arranged along the length direction of the first air vent; each supporting component is arranged along the length extending direction of the fixing component; and, the guiding track is a guiding groove that penetrates through the supporting component in its thickness direction on each supporting component; when looking from the thickness direction of the supporting component, the guiding groove is in an S-shaped curved shape along the length direction of the supporting component, and one end of each guiding groove close to the fixing component extends upward, and one end close to the auxiliary air direction control plate extends downward.

[0011] According to another specific embodiment of the present invention, for the air direction adjusting assembly of the air conditioner disclosed in the embodiment of the present invention, at least two supporting members are arranged at equal intervals in the length extension direction of the fixing member, and two of the supporting members are respectively arranged at both ends of the fixing member.

[0012] According to another specific embodiment of the present invention, for the air direction adjusting assembly of the air conditioner disclosed in the embodiment of the present invention, in the closed state, the main air direction control plate and the auxiliary air direction control plate cover the first ventilation opening in a "<" shape; and, the opposite ends of the main air direction control plate and the auxiliary air direction control plate are in contact; the other end of the main air direction control plate is movably abutted against the housing on one side of the first ventilation opening; the other end of the auxiliary air direction control plate is movably abutted against the housing on the other side of the first ventilation opening.

[0013] With the above solution, in the closed state, the main air direction control plate and the auxiliary air direction control plate completely cover the first ventilation opening, which can keep the appearance of the indoor unit of the air conditioner relatively flat and will not expose the first ventilation opening.

[0014] According to another specific embodiment of the present invention, for the air direction adjusting assembly of the air conditioner disclosed in the embodiment of the present invention, when the main connecting member is driven to rotate around the first rotating shaft, the main air direction control plate is driven to rotate around the first rotating shaft, and the auxiliary air direction control plate rotates in a direction opposite to the rotation direction of the main air direction control plate; in the first open state, the main air direction control plate and the auxiliary air direction control plate are parallel to each other and parallel to the opening direction of the first ventilation opening; in the second open state, the main air direction control plate and the auxiliary air direction control plate are parallel to each other and inclined downward relative to the opening direction of the first ventilation opening.

[0015] With the above solution, the air outlet direction of the first ventilation opening can be adjusted by the main air direction control plate and the auxiliary air direction control plate, so that the indoor unit of the air conditioner blows air in a predetermined direction, improving the ventilation effect.

[0016] According to another specific embodiment of the present invention, for the air direction adjusting assembly of the air conditioner disclosed in the embodiment of the present invention, it further includes a plurality of adjusting vanes; each adjusting vane is arranged inside the main air direction control plate and / or the auxiliary air direction control plate, arranged at equal intervals and parallel to each other along the length direction of the first ventilation opening; each adjusting vane can rotate around an axis parallel to the width direction of the first ventilation opening in the length direction of the first ventilation opening to adjust the direction of the air blown out of the first ventilation opening in the length direction of the first ventilation opening.

[0017] With the above solution, since there are adjusting vanes for adjusting the direction of the air blown out of the first ventilation opening in the length direction of the first ventilation opening, the direction of the air blown out of the first ventilation opening can be adjusted not only in the width direction of the first ventilation opening but also in the length direction of the first ventilation opening. The indoor unit can blow air towards a specific direction via the adjusting vanes and the wind direction control board, improving the ventilation effect.

[0018] According to another specific embodiment of the present invention, for the wind direction adjusting assembly of the air conditioner disclosed in the embodiment of the present invention, the driving component is a stepping motor fixedly arranged inside the first ventilation opening.

[0019] The embodiment of the present invention also discloses an indoor unit of an air conditioner, including: a housing, on which a first ventilation opening and a second ventilation opening are provided, and a air supply path is formed between the first ventilation opening and the second ventilation opening; a heat exchanger, which is arranged inside the housing; a air supply device, which blows out the air whose temperature is adjusted by the heat exchanger; and the wind direction adjusting assembly of the air conditioner described in any of the above embodiments; and, the wind direction adjusting assembly of the air conditioner adjusts the direction of the air blown out of the first ventilation opening of the indoor unit.

[0020] According to another specific embodiment of the present invention, for the indoor unit of the air conditioner disclosed in the embodiment of the present invention, the upper surface of the housing slopes downward from the rear side to the front side of the housing, and the lower surface of the housing slopes upward from the rear side to the front side, so that the thickness of the housing becomes smaller from the rear side to the front side and a first ventilation opening is formed on the front side; and, the first ventilation opening is located on one side of the heat exchanger and opens in the housing towards the first direction; and, the second ventilation opening is located on the other side of the heat exchanger and opens in the housing towards the second direction different from the first direction; and, when the air supply device is in the air supply state of refrigeration, air enters from the second ventilation opening, passes through the air supply path, and is blown out from the first ventilation opening; and, the air supply device includes a first fan, a second fan and a fan control part; wherein, the first fan is arranged on one side of the heat exchanger and the second fan is arranged on the other side of the heat exchanger; the fan control part makes the rotation speed of the first fan greater than that of the second fan, the first fan rotates counterclockwise and the second fan rotates clockwise to control the indoor unit to be in the air supply state of refrigeration; and, the indoor unit further includes a filtering part; wherein, the filtering part is arranged inside the first ventilation opening, one end of the filtering part abuts against the inner wall of the housing inside the first ventilation opening, and the other end abuts against the outer wall of the first fan; when the indoor unit is in the air supply state of refrigeration, the air entering from the second ventilation opening passes through the air supply path and then is blown out from the first ventilation opening after passing through the filtering part.

[0021] The beneficial effects of the present invention are:

[0022] The wind direction adjustment component of the air conditioner provided by this solution increases the opening area of the wind direction control board of the indoor unit of the air conditioner by setting two wind direction control boards, thereby being able to reduce the ventilation resistance and improve the ventilation effect. Moreover, the main connection member that drives the main wind direction control board to rotate and the auxiliary connection member that drives the auxiliary wind direction control board to rotate are arranged in a pivotally rotatable manner through the third rotating shaft. Only one driving component needs to be set for the main connection member to drive the auxiliary connection member to drive the auxiliary wind direction control board to rotate, without setting driving components for the main connection member and the auxiliary connection member respectively, saving the layout cost and reducing the layout difficulty. In addition, since the second rotating shaft and the third rotating shaft can move within the guiding track, when the driving component drives the main connection member, it can also drive the end of the auxiliary connection member to move relative to the base, thereby being able to adjust the air outlet direction restricted by the main wind direction control board and the auxiliary wind direction control board, enabling the indoor unit to blow air towards the ground or a specific direction, further improving the ventilation effect.

[0023] Furthermore, for the indoor unit of the air conditioner provided by this solution, due to having the above-mentioned wind direction adjustment component, the opening area of the wind direction control board of this indoor unit is increased, and the ventilation effect is better. And only setting one driving component can drive the two wind direction control boards, saving the layout space and enabling the indoor unit to develop towards a thinner and lighter shape. In addition, since the main wind direction control board and the auxiliary wind direction control board can move from the opening direction parallel to the first ventilation opening to the direction inclined downward relative to the opening direction of the first ventilation opening, this indoor unit can blow air towards a specific direction, further improving the ventilation effect.

For those of ordinary skill in the art, the specific meanings of the above terms in this embodiment can be understood according to specific situations.

[0034] To make the purpose, technical solutions and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below with reference to the drawings.

[0035] To solve the problems in the prior art that the air outlet effect of the air conditioner is not good and the presence of multiple wind direction plates requires a large number of driving motors, an embodiment of the present invention provides a wind direction adjustment assembly for an air conditioner. Specifically, the wind direction adjustment assembly for the air conditioner provided in this specific embodiment includes a base, a movable member, and a driving member.

[0036] Further, in the wind direction adjustment assembly of the air conditioner according to the present invention, referring to Figure 1 , the base is fixedly arranged inside the first ventilation opening 11 of the indoor unit of the air conditioner. The fixed connection manner between the base and the indoor unit of the air conditioner includes but is not limited to threaded connection, spline connection, wedge pin connection, etc. And, in this specific embodiment, the base cannot rotate relative to the indoor unit.

[0037] Further, in the wind direction adjustment assembly of the air conditioner according to the present invention, referring to Figure 1 , the movable assembly includes a main wind direction control plate 1, an auxiliary wind direction control plate 2, a main connection member 3, and an auxiliary connection member 4. One end of the main connection member 3 is fixedly connected to the main wind direction control plate 1, and the other end is pivotally arranged on the base through a first rotating shaft 5. One end of the auxiliary connection member 4 is fixedly connected to the auxiliary wind direction control plate 2, and the other end is pivotally arranged on the base through a second rotating shaft 6. The ends of the main connection member 3 and the auxiliary connection member 4 close to the base are pivotally connected together through a third rotating shaft 7. Both the second rotating shaft 6 and the third rotating shaft 7 are arranged in a guiding track 8 on the base. The driving member is connected to the main connection member 3 to drive the main connection member 3 to rotate relative to the base around the first rotating shaft 5. That is to say, the main connection member 3 is used to drive the main wind direction control plate 1 to rotate relative to the base around the first rotating shaft 5, and the auxiliary connection member 4 is used to drive the auxiliary wind direction control plate 2 to rotate relative to the base around the second rotating shaft 6. And, since the main connection member 3 and the auxiliary connection member 4 are connected together through the third rotating shaft 7, when the driving member drives the main connection member 3 to rotate, it can drive the auxiliary connection member 4 to rotate, and at the same time drive the second rotating shaft 6 and the third rotating shaft 7 to move along the shape of the guiding track 8. It should be noted that, in this specific embodiment, both the main connection member 3 and the auxiliary connection member 4 are in a plate-like structure to provide better support for the main wind direction control plate 1 and the auxiliary wind direction control plate 2. Of course, the main connection member 3 and the auxiliary connection member 4 can also be in a rod-like shape to save space and make the air conditioner lighter. Those skilled in the art can determine the specific structures of the main connection member 3 and the auxiliary connection member 4 according to actual needs, and the main connection member 3 and the auxiliary connection member 4 can be selected with different structures to achieve a better balance between the support effect and light weight.

[0038] Further, in the wind direction adjustment assembly of the air conditioner according to the present invention, referring to Figure 1, when the driving component drives the main connecting member 3 along the first direction, the main connecting member 3 is driven to rotate around the first rotating shaft 5, and the auxiliary connecting member 4 is linked to rotate around the second rotating shaft 6 through the third rotating shaft 7, so as to drive the main air direction control plate 1 and the auxiliary air direction control plate 2 to move from the closed state to the first open state where the first ventilation opening 11 is exposed. With the continuous driving of the driving component, the main connecting member 3 drives the second rotating shaft 6 and the third rotating shaft 7 to move along the guiding track 8 through the third rotating shaft 7, so as to drive the main air direction control plate 1 and the auxiliary air direction control plate 2 to move from the first open state to the second open state which is inclined downward relative to the first ventilation opening 11. That is to say, the air direction adjusting assembly provided by this specific embodiment has three states: a closed state, a first open state, and a second open state. Refer to Figure 1 , in the closed state, the main air direction control plate 1 and the auxiliary air direction control plate 2 cover the first ventilation opening 11 to close the first ventilation opening 11, and this state can be understood as the indoor unit of the air conditioner being in the closed state. Refer to Figure 2 , in the first open state, the main air direction control plate 1 and the auxiliary air direction control plate 2 open the first ventilation opening 11, and this state can be understood as the indoor unit of the air conditioner being in the working state and blowing air in a direction parallel to the first ventilation opening 11. Refer to Figure 3 , in the second open state, the main air direction control plate 1 and the auxiliary air direction control plate 2 open the first ventilation opening 11 and are inclined downward relative to the first ventilation opening 11, and this state can be understood as the indoor unit of the air conditioner being in the working state and blowing air in a direction downward relative to the first ventilation opening 11.

[0039] It should be understood that in this specific embodiment, the first direction is the direction in which the main air direction control plate 1 is away from the auxiliary air direction control plate 2. And this first direction is the direction of rotation of the output shaft of the driving component. The rotation direction of the auxiliary air direction control plate 2 is the direction opposite to the first direction. In this way, when the driving component drives the main connecting member 3 along the first direction, it can drive the main air direction control plate 1 and the auxiliary air direction control plate 2 to rotate in a direction away from each other, so that the main air direction control plate 1 and the auxiliary air direction control plate 2 move from the closed state to the first open state. And when the output shaft of the driving component continues to rotate in the first direction, the main air direction control plate 1 continues to rotate in the first direction. At this time, the second rotating shaft 6 and the third rotating shaft 7 will move along the guiding track 8 and drive the auxiliary air direction control plate 2 to rotate in the direction opposite to the rotation direction when moving from the closed state to the first open state, so that the main air direction control plate 1 and the auxiliary air direction control plate 2 move from the first open state to the second open state. It should also be understood that in this specific embodiment, the driving component can also drive the main connecting member 3 along the second direction opposite to the first direction, so that the main air direction control plate 1 and the auxiliary air direction control plate 2 can move from the second open state to the first open state and then move to the closed state.

[0040] Furthermore, the airflow control assembly of the air conditioner according to the present invention has a configuration in which, by providing two airflow control panels, namely a main airflow control panel 1 and an auxiliary airflow control panel 2, the opening area of the airflow control panel of the indoor unit of the air conditioner can be increased, thereby reducing ventilation resistance and improving ventilation efficiency. Furthermore, the main connecting member 3, which drives the rotation of the main airflow control panel 1, and the auxiliary connecting member 4, which drives the rotation of the auxiliary airflow control panel 2, are arranged to pivotally rotate via a third rotating shaft 7. This allows only a single driving component for the main connecting member 3 to drive the auxiliary connecting member 4 to rotate in conjunction with the auxiliary airflow control panel 2, eliminating the need for separate driving components for the main connecting member 3 and the auxiliary connecting member 4. This reduces layout costs and eases layout difficulty. Furthermore, because the second rotating shaft 6 and the third rotating shaft 7 are movable within the guide rail 8, when the driving component drives the main connecting member 3, it also drives the end of the auxiliary connecting member 4 relative to the base. This allows the airflow direction, which is limited by the main airflow control panel 1 and the auxiliary airflow control panel 2, to be adjusted so that the indoor unit blows air toward the ground or in a specific direction, further improving ventilation efficiency.

[0041] Further, in the wind direction adjustment assembly of the air conditioner according to the present invention, reference is made to Figure 1 , the driving component is a stepper motor fixedly arranged on the inner side of the first vent 11. Moreover, in this specific embodiment, the driving component can be fixedly arranged by being clipped or threadedly connected to the base. It should be noted that the output shaft of the driving component is fixedly connected to the first rotating shaft 5 to drive the first rotating shaft 5 to rotate. Those skilled in the art can select other components that can drive the first rotating shaft 5 to rotate according to actual needs, such as a servo motor or an AC motor, and this specific embodiment does not impose any restrictions on this. Moreover, using a stepper motor to drive the first rotating shaft 5 can facilitate the control of the first rotating shaft 5,

[0042] Further, in the wind direction adjustment assembly of the air conditioner according to the present invention, reference is made to Figure 1 The first vent 11 opens horizontally, and the main wind direction control plate 1 is located below the auxiliary wind direction control plate 2. In the extension direction of the main connecting member 3, the first rotating shaft 5 is closer to one end of the main connecting member 3 than the third rotating shaft 7, and in the extension direction of the auxiliary connecting member 4, the third rotating shaft 7 is closer to one end of the auxiliary connecting member 4 than the second rotating shaft 6.

[0043] Further, in the wind direction adjustment assembly of the air conditioner according to the present invention, reference is made to Figure 1, when viewed along the axial direction of the first rotating shaft 5, when the main air direction control plate 1 and the auxiliary air direction control plate 2 are in the closed state, the first rotating shaft 5, the second rotating shaft 6 and the third rotating shaft 7 are arranged obliquely with respect to the first ventilation opening 11. Among them, in the vertical direction, the third rotating shaft 7 is located between the first rotating shaft 5 and the second rotating shaft 6, and the first rotating shaft 5 is closer to the outer side of the first ventilation opening 11 than the second rotating shaft 6. And at this time, the first rotating shaft 5, the second rotating shaft 6 and the third rotating shaft 7 are arranged in a straight line or in an arc with a small curvature, and the third rotating shaft 7 is located between the first rotating shaft 5 and the second rotating shaft 6.

[0044] Furthermore, in the air direction adjusting assembly of the air conditioner according to the present invention, referring to Figure 2 , when viewed along the axial direction of the first rotating shaft 5, when the main air direction control plate 1 and the auxiliary air direction control plate 2 are in the first open state, the first rotating shaft 5, the second rotating shaft 6 and the third rotating shaft 7 are arranged in a triangle. Among them, in the vertical direction, the second rotating shaft 6 is located between the first rotating shaft 5 and the third rotating shaft 7, and the first rotating shaft 5 and the third rotating shaft 7 are closer to the outer side of the first ventilation opening 11 than the second rotating shaft 6. Preferably, at this time, the first rotating shaft 5, the second rotating shaft 6 and the third rotating shaft 7 are arranged in an acute triangle. In the horizontal direction, the first rotating shaft 5 is closer to the outer side of the first ventilation opening 11 than the second rotating shaft 6. It should be noted that when the main air direction control plate 1 and the auxiliary air direction control plate 2 move from the closed state to the first open state, the position of the first rotating shaft 5 does not change, and the second rotating shaft 6 and the third rotating shaft 7 both move towards the outer side of the first ventilation opening 11, and the second rotating shaft 6 moves downward and the third rotating shaft 7 moves upward.

[0045] Furthermore, in the air direction adjusting assembly of the air conditioner according to the present invention, referring to Figure 3, when viewed along the axial direction of the first rotating shaft 5, when the main wind direction control plate 1 and the auxiliary wind direction control plate 2 are in the second open state, the first rotating shaft 5, the second rotating shaft 6 and the third rotating shaft 7 are arranged in a triangle. Among them, in the vertical direction, the first rotating shaft 5 is located at a lower position than the second rotating shaft 6 and the third rotating shaft 7, and the third rotating shaft 7 is located closer to the outside of the first ventilation opening 11 than the first rotating shaft 5 and the second rotating shaft 6. Preferably, at this time, the first rotating shaft 5, the second rotating shaft 6 and the third rotating shaft 7 are arranged in an acute triangle. In the horizontal direction, the second rotating shaft 6 is closer to the outside of the first ventilation opening 11 than the first rotating shaft 5. It should be noted that when the main wind direction control plate 1 and the auxiliary wind direction control plate 2 move from the first open state to the second open state, the position of the first rotating shaft 5 remains unchanged, and the second rotating shaft 6 and the third rotating shaft 7 continue to move towards the outside of the first ventilation opening 11, and the second rotating shaft 6 moves upward and the third rotating shaft 7 moves downward. With such a structure, the third rotating shaft 7 is used to connect the main connecting member 3 and the auxiliary connecting member 4 together, so as to realize that only driving the main connecting member 3 can drive the auxiliary connecting member 4 to rotate, and the movement of the second rotating shaft 6 and the third rotating shaft 7 in the guiding track 8 is used to drive the change of the air outlet direction formed by the main wind direction control plate 1 and the auxiliary wind direction control plate 2. Only corresponding rotating shafts are arranged within the original spatial range of the main connecting member 3 and the auxiliary connecting member 4, and a guiding track 8 for the movement of the rotating shafts is arranged on the base, without occupying extra space, which is beneficial to reducing the volume of the air conditioner.

[0046] Furthermore, in the wind direction adjusting assembly of the air conditioner according to the present invention, referring to Figure 1 , the base includes a fixing component and at least two supporting components 9. Among them, the fixing component is fixedly arranged inside the first ventilation opening 11 and arranged along the length direction of the first ventilation opening 11. Each supporting component 9 is arranged along the length extension direction of the fixing component. In this specific embodiment, the fixing component is a fixing plate with a length equal to or close to the length of the first ventilation opening 11, and it is fixed inside the first ventilation opening 11 by means of fixed connection such as threaded connection or welding. The supporting component 9 has a sheet-like structure and is fixed to the fixing component by means of integral molding or welding. The thickness direction of the supporting component 9 is parallel to the length extension direction of the fixing component.

[0047] Still further, in the wind direction adjusting assembly of the air conditioner according to the present invention, referring to Figure 1, at least two support members 9 are arranged at equal intervals in the length extension direction of the fixed member, and two of the support members 9 are respectively arranged at both ends of the fixed member. In this specific embodiment, two, three or even more support members 9 can be provided. When two support members 9 are provided, the two support members 9 are respectively arranged at both ends of the fixed member. When three support members 9 are provided, two of the support members 9 are respectively arranged at both ends of the fixed member, and the other support member 9 is arranged between the two support members 9 at both ends and is equidistant from the support members 9 at both ends. Four support members 9 can also be provided. When four support members 9 are provided, two of the support members 9 are respectively arranged at both ends of the fixed member, and the other two support members 9 are arranged at the middle position of the fixed member, and the four support members 9 are arranged at equal intervals. In this specific embodiment, three support members 9 are provided. With such an arrangement, it is possible to avoid the situation that the support is unstable due to too few support members 9, which in turn causes the main connection member 3 and the auxiliary connection member 4 to shake, and it is also possible to avoid the problem of increasing the weight of the air conditioner and the layout cost due to too many support members 9.

[0048] Further, in the wind direction adjustment assembly of the air conditioner according to the present invention, refer to Figure 1 , the guide rail 8 is a guide groove that penetrates the support member 9 in the thickness direction of each support member 9. When viewed from the thickness direction of the support member 9, the guide groove is bent in an S shape along the length direction of the support member 9, and one end of each guide groove close to the fixed member extends upward, and one end close to the auxiliary wind direction control plate 2 extends downward.

[0049] Further, in the wind direction adjustment assembly of the air conditioner according to the present invention, refer to Figure 1, in the closed state, the main air direction control plate 1 and the auxiliary air direction control plate 2 cover the first ventilation opening 11 in an "<" shape. Moreover, the opposite ends of the main air direction control plate 1 and the auxiliary air direction control plate 2 are in contact with each other. The other end of the main air direction control plate 1 is movably abutted against the housing 10 on one side of the first ventilation opening 11; the other end of the auxiliary air direction control plate 2 is movably abutted against the housing 10 on the other side of the first ventilation opening 11. That is to say, in the closed state, one end of the main air direction control plate 1 is in contact with one end of the auxiliary air direction control plate 2, and when viewed from the axial direction of the first rotating shaft 5, the main air direction control plate 1 and the auxiliary air direction control plate 2 cover the first ventilation opening 11 in an "<" shape. Moreover, the other end of the main air direction control plate 1 and the other end of the auxiliary air direction control plate 2 are in contact with the housing 10 on both sides of the first ventilation opening 11, so that the main air direction control plate 1 and the auxiliary air direction control plate 2 completely cover the first ventilation opening 11. With such a structure, in the closed state, the main air direction control plate 1 and the auxiliary air direction control plate 2 can completely cover the first ventilation opening 11, enabling the indoor unit of the air conditioner to maintain a relatively flat appearance and preventing the ventilation opening from being exposed.

[0050] Furthermore, in the air direction adjustment assembly of the air conditioner according to the present invention, referring to Figure 1 , when the main connecting member 3 is driven to rotate around the first rotating shaft 5, the main air direction control plate 1 is driven to rotate around the first rotating shaft 5, and the auxiliary air direction control plate 2 rotates in a direction opposite to the rotation direction of the main air direction control plate 1. Referring to Figure 2 , in the first open state, the main air direction control plate 1 and the auxiliary air direction control plate 2 are parallel to each other and parallel to the opening direction of the first ventilation opening 11. Referring to Figure 3 , in the second open state, the main air direction control plate 1 and the auxiliary air direction control plate 2 are parallel to each other and inclined downward relative to the opening direction of the first ventilation opening 11. With such a structure, the air outlet direction of the first ventilation opening 11 can be adjusted by the main air direction control plate 1 and the auxiliary air direction control plate 2, enabling the indoor unit of the air conditioner to blow air towards a predetermined direction and improving the ventilation effect.

[0051] Furthermore, in the air direction adjusting assembly of the air conditioner according to the present invention, a plurality of adjusting vanes are further included. Each adjusting vane is arranged inside the main air direction control plate 1 and / or the auxiliary air direction control plate 2, and is arranged at equal intervals and parallel to each other along the length direction of the first air vent 11. Each adjusting vane can rotate around an axis parallel to the width direction of the first air vent 11 in the length direction of the first air vent 11, so as to adjust the direction of the air blown out of the first air vent 11 in the length direction of the first air vent 11. That is to say, the adjusting vane can be installed inside the main air direction control plate 1 or the auxiliary air direction control plate 2, or the adjusting vane can be installed inside both the main air direction control plate 1 and the auxiliary air direction control plate 2 to control the direction of the air blown out of the first air vent 11 in the horizontal direction. Specifically, the adjusting vane is flat and extends in the width direction of the first air vent 11, and is arranged in parallel at a specified interval. Those skilled in the art can set the interval between adjacent adjusting vanes according to actual needs. It should be noted that the plurality of adjusting vanes are connected via the same operating rod to synchronously control all the adjusting vanes. The operating rod can be set to be manual, or a driving motor can be additionally provided for driving, and this specific embodiment does not limit this. With such a structure, since there are adjusting vanes for adjusting the direction of the air blown out of the first air vent 11 in the length direction of the first air vent 11, the direction of the air blown out of the first air vent 11 can be adjusted not only in the vertical direction but also in the horizontal direction. The indoor unit can blow air towards a specific direction via the adjusting vanes and the air direction control plate, improving the ventilation effect.

[0052] Next, the working process of the air direction adjusting assembly of the air conditioner provided in this specific embodiment will be described. It should be explained that this specific embodiment only describes the process of the air direction adjusting assembly moving from the closed state to the first open state and then to the second open state. For the process of moving from the second open state to the first open state and then to the closed state, those skilled in the art can easily infer it, and this specific embodiment will not elaborate.

[0053] Specifically, referring to Figure 1 , when the indoor unit of the air conditioner is in a stopped operating state, the main air direction control plate 1 and the auxiliary air direction control plate 2 are in the closed state. At this time, the main air direction control plate 1 and the auxiliary air direction control plate 2 completely cover the first air vent 11 in a "<" shape. When looking along the axial direction of the first rotating shaft 5, the second rotating shaft 6 is located at the end position of the guiding track 8 close to the inner side of the first air vent 11, and the second rotating shaft 6 is closer to the inner side of the first air vent 11 than the third rotating shaft 7.

[0054] Referring to Figure 2, when the indoor unit of the air conditioner is in the operating state, the main air direction control board 1 and the auxiliary air direction control board 2 first move from the closed state to the first open state. More specifically, the output shaft of the driving component rotates in the direction away from the auxiliary air direction control board 2 towards the main air direction control board 1. In Figure 1 , the output shaft of the driving component rotates counterclockwise to drive the main connecting member 3 in the closed state, and drives the main connecting member 3 to rotate along the first direction around the first rotating shaft 5. In Figure 1 , the main connecting member 3 rotates counterclockwise around the first rotating shaft 5. When the main connecting member 3 rotates counterclockwise, it will drive the end of the main connecting member 3 close to the inner side of the first ventilation opening 11 to move towards the outer side of the first ventilation opening 11. At this time, when looking along the axial direction of the first rotating shaft 5, the second rotating shaft 6 will move along the guiding track 8 towards the outer side of the first ventilation opening 11, thereby driving the third rotating shaft 7 to move towards the outer side of the first ventilation opening 11. Since both the second rotating shaft 6 and the third rotating shaft 7 are located at the other end of the auxiliary connecting member 4, the movement of the second rotating shaft 6 and the third rotating shaft 7 will drive the auxiliary connecting member 4 to rotate relative to the base, and further cause the auxiliary air direction control board 2 to also rotate clockwise relative to the base. If the driving component continues to rotate, the main air direction control board 1 and the auxiliary air direction control board 2 will be in a parallel state and parallel to the opening direction of the first ventilation opening 11. At this time, the third rotating shaft 7 is located at the middle position of the guiding track 8 and is slightly close to the outer side of the first ventilation opening 11.

[0055] Reference Figure 3 , when the indoor unit of the air conditioner is in the operating state, the main air direction control board 1 and the auxiliary air direction control board 2 can also move from the first open state to the second open state. When the driving component continues to drive its output shaft to rotate counterclockwise in the first operating state, it will drive the main connecting member 3 to continue rotating counterclockwise, and drive the main air direction control board 1 to rotate counterclockwise. The rotation of the main connecting member 3 will drive the second rotating shaft 6 and the third rotating shaft 7 to continue moving along the guiding track 8 towards the outer side of the first ventilation opening 11. Limited by the shape of the guiding track 8, the auxiliary air direction control board 2 will rotate counterclockwise under the drive of the auxiliary connecting member 4 and always remain parallel to the main air direction control board 1 during this process. When the third rotating shaft 7 is located at the end of the guiding track 8 close to the outer side of the first ventilation opening 11, the main air direction control board 1 and the auxiliary air direction control board 2 are in a state of being inclined downward relative to the opening direction of the first ventilation opening 11, that is, the second open state.

[0056] Based on the above air direction adjustment component of the air conditioner, an embodiment of the present invention also provides an indoor unit of an air conditioner. Specifically, reference Figure 1 , the indoor unit of the air conditioner provided by the specific embodiment of the present invention includes a housing 10, a heat exchanger 13, a blowing device, and the air direction adjustment component of the air conditioner described in the above embodiment. In this specific embodiment,Figure 1 The left side is set as the front of the indoor unit, and the right side is set as the back of the indoor unit. The indoor unit of the air conditioner is generally arranged at the corner where the top and side walls of the room match. The indoor unit and the outdoor unit installed outdoors are connected by connecting pipelines to form an air conditioner. Of course, this specific embodiment is only described with the indoor unit of a wall-mounted air conditioner. This indoor unit can also be an embedded type embedded in the indoor ceiling, a wall-mounted type installed at a high place indoors, or a floor-standing type placed on the ground, etc.

[0057] Furthermore, in the indoor unit of the air conditioner according to the present invention, referring to Figure 1 , a first ventilation opening 11 and a second ventilation opening 12 are provided on the housing 10, and a air supply path is formed between the first ventilation opening 11 and the second ventilation opening 12. The heat exchanger 13 is arranged inside the housing 10. The air supply device blows out the air whose temperature is adjusted by the heat exchanger 13. The air direction adjusting assembly of the air conditioner adjusts the direction of the air blown out from the first ventilation opening 11 of the indoor unit. In this specific embodiment, the air supply device is a blower.

[0058] Furthermore, in the indoor unit of the air conditioner according to the present invention, the upper surface of the housing 10 slopes downward from the rear side to the front side of the housing 10, and the lower surface of the housing 10 slopes upward from the rear side to the front side, so that the thickness of the housing 10 becomes smaller from the rear side to the front side and a first ventilation opening 11 is formed on the front side.

[0059] Furthermore, in the indoor unit of the air conditioner according to the present invention, referring to Figure 1 , the first ventilation opening 11 is located on one side of the heat exchanger 13 and opens in the housing 10 toward the first direction. The second ventilation opening 12 is located on the other side of the heat exchanger 13 and opens in the housing 10 toward the second direction different from the first direction. In this specific embodiment, the first direction is taken as the horizontal direction and the second direction is taken as the vertically downward direction for illustration. Specifically, the first ventilation opening 11 is provided on the front of the housing 10 and opens forward, and the second ventilation opening 12 is provided on the rear side of the housing 10 and opens downward. Of course, those skilled in the art can arbitrarily select the opening directions of the first ventilation opening 11 and the second ventilation opening 12. Inside the housing 10, an air supply path is formed from the second ventilation opening 12 to the first ventilation opening 11. And, the heat exchanger 13 is arranged inside the housing 10, and the upper part is inclined toward the rear of the housing 10. When viewed from the axial direction of the first rotating shaft 5, the heat exchanger 13 has a honeycomb structure, and a refrigerant is provided in each honeycomb structure for heat exchange. The heat exchanger 13 functions as an evaporator when the air conditioner is cooling to lower the temperature of the surrounding air. Of course, it functions as a condenser when the air conditioner is heating to raise the surrounding temperature. With such a structure, since the heat exchanger 13 is inclined, the housing 10 can be made thinner and is convenient for layout.

[0060] Furthermore, in the indoor unit of the air conditioner according to the present invention, referring to Figure 1 , when the air supply device is in the air supply state for refrigeration, air enters from the second air vent 12, passes through the air supply path, and blows out from the first air vent 11. That is to say, during refrigeration, air is inhaled from below and blown out horizontally. And the hot air blown out from the first air vent 11 flows along the top of the room and descends along the side wall of the room opposite to the indoor unit. Then, the air flows along the floor and ascends along the side wall of the room where the indoor unit is installed, and is inhaled from the second air vent 12.

[0061] Furthermore, in the indoor unit of the air conditioner according to the present invention, referring to Figure 1 , the air supply device includes a first fan 14, a second fan 15, and a fan control unit. Among them, the first fan 14 is arranged on one side of the heat exchanger 13, and the second fan 15 is arranged on the other side of the heat exchanger 13. The fan control unit can be a driving motor or other components capable of driving the first fan 14 and the second fan 15 to rotate. In this specific embodiment, in order to control the rotation speeds of the first fan 14 and the second fan 15 respectively, the fan control unit includes two driving motors that drive the first fan 14 and the second fan 15 respectively.

[0062] Furthermore, in the indoor unit of the air conditioner according to the present invention, the fan control unit makes the rotation speed of the first fan 14 greater than that of the second fan 15, the first fan 14 rotates counterclockwise, and the second fan 15 rotates clockwise to control the indoor unit to be in the air supply state for refrigeration. It should be noted that in this specific embodiment, the air flow is generated and refrigerated by the different rotation speeds of the first fan 14 and the second fan 15.

[0063] Furthermore, in the indoor unit of the air conditioner according to the present invention, referring to Figure 1 , the indoor unit further includes a filtering unit 16. The filtering unit 16 is arranged inside the first air vent 11. One end of the filtering unit 16 abuts against the inner wall of the housing 10 inside the first air vent 11, and the other end abuts against the outer wall of the first fan 14. When the indoor unit is in the air supply state for refrigeration, the air entering from the second air vent 12 passes through the air supply path and then blows out from the first air vent 11 after passing through the filtering unit 16. With such a structure, since the filtering unit 16 is provided, the air passing through the air supply path can be blown out more evenly and without impurities, improving the air supply quality.

[0064] Although the present invention has been illustrated and described with reference to certain preferred embodiments thereof, those of ordinary skill in the art should understand that the above is a further detailed description of the present invention in connection with specific embodiments, and it cannot be determined that the specific implementation of the present invention is only limited to these descriptions. Those skilled in the art can make various changes in form and detail, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
