Description

Air outlet assembly and air conditioner

Technical Field

The utility model relates to the technical field of air conditioners, in particular to an air outlet assembly and an air conditioner.

Background

The air conditioner can refrigerate and heat, and two functions are both sent into a room through an air supply system, wherein an air outlet assembly is an important part in the air supply system. The wind sweeping blades are connected to the wind outlet frame through cranks, and the swinging ends of the cranks are hinged to connecting rods to realize synchronous swinging through the connecting rods. In the existing air outlet assembly, a driving crank is required to drive a connecting rod to move, and the connecting rod drives each driven crank to rotate, so that each blade synchronously swings, the swinging mode of the driving crank is required to be consistent with the height of each driven crank, and the blade is easy to block. In other words, the swing angle of the driving crank and the extending direction of the force arm in the conventional air outlet assembly need to be the same as those of the driven crank. This can result in severely limited construction and mounting of the drive crank and poor flexibility.

SUMMERY OF THE UTILITY MODEL

The utility model solves the problem that the existing air outlet assembly is not flexible enough to the structure and the installation mode of a driving crank.

In order to solve the above problems, in a first aspect, the present invention provides an air outlet assembly, including a base, a driving crank, a driven crank, a connecting member, and a blade disposed on the driven crank, where the driving crank and the driven crank both have a fixed end and a swing end, the fixed ends of the driving crank and the driven crank are both rotatably connected to the base, the blade is fixedly connected to the fixed end of the driven crank, the connecting member is rotatably connected to the swing end of the driven crank, and the connecting member is provided with a strip-shaped hole, and the strip-shaped hole is matched with the swing end of the driving crank, so that when the driving crank drives the driven crank to rotate through the connecting member, the swing end of the driving crank can slide and rotate in the strip-shaped hole.

In the embodiment of the application, the swinging end of the driving crank is matched with the strip-shaped hole on the connecting piece, so that the connecting end of the driving crank can rotate relative to the connecting piece and can also translate relative to the connecting piece. Under the structure, the length and the extension direction of the force arm of the driving crank are allowed to be different from those of the driven crank, and the phenomenon that the driving crank is blocked and cannot swing together can not occur, because the swinging end of the driving crank can slide in the strip-shaped hole. It can be seen that the air-out subassembly that this application embodiment provided is through setting up the bar hole on the connecting piece for the structure and the mounting means of initiative crank have had more choices, and the flexibility is better.

In an alternative embodiment, the arm length of the driving crank is greater than the arm length of the driven crank. In this embodiment, the arm length of the driving crank is greater than that of the driven crank, so that after the driving crank generates a certain rotation angle, the rotation angle of the driven crank is larger, and in a certain scene, the driving crank can drive the driven crank with a smaller rotation angle.

In an alternative embodiment, the outlet assembly includes a plurality of driven cranks arranged in a first direction.

In an alternative embodiment, each time the driven crank rotates with the driving crank, the driven crank rotates in the opposite direction to the driving crank. In this embodiment, because the strip-shaped hole is provided, the movable end of the driving crank is allowed to slide in the strip-shaped hole, so that the direction of the rotation angle of the driving crank and the direction of the rotation angle of the driven crank can be set to be opposite, for example, the swinging end of the driving crank is closer to the outer side of the air outlet of the air conditioner than the fixed end, and the swinging end of the driven crank is closer to the inner side of the air outlet of the air conditioner than the fixed end, so that when the driving crank drives the driven crank to rotate, the rotating directions of the driving crank and the driven crank are opposite. This arrangement can satisfy the arrangement requirement in the air conditioner in some cases.

In an alternative embodiment the rotation of the driving crank relative to the base has a first extreme position and a second extreme position, the rotation angle of the driving crank between the first extreme position and the second extreme position being between 50 ° and 70 °, and the driven crank rotating between 100 ° and 120 ° during the rotation of the driving crank from the first extreme position to the second extreme position.

In this embodiment, under the condition that the end surface of the strip-shaped hole does not interfere with the driving crank, the rotation ratio is adjusted by adjusting the relative length of the force arms of the driving crank and the driven crank, so that the rotation range of the driving crank is 50-70 degrees, the corresponding rotation range of the driven crank is 100-120 degrees, and the design requirements of the air conditioner can be better met.

In an alternative embodiment, the strip-shaped apertures extend in a second direction, the second direction being perpendicular to the first direction. The extending direction of the strip-shaped holes and the arrangement direction of the driven cranks are set to be vertical, so that the force application direction of the driving crank to the connecting piece is consistent with the connecting line direction of the swinging ends of the driven cranks and is the first direction, and the arrangement mode is more favorable for the transmission efficiency.

In an alternative embodiment, the base includes a first mounting portion and a second mounting portion, the first mounting portion is strip-shaped and extends along the first direction, the second mounting portion is connected to one end of the first mounting portion, the driven crank is connected to the first mounting portion, and the driving crank is connected to the second mounting portion.

In an alternative embodiment, the second mounting portion is strip-shaped, and one end of the second mounting portion is connected to the end of the first mounting portion, so that the connecting piece is L-shaped.

In an alternative embodiment, the fixed end of the driven crank is provided with a connecting shaft, the axis of the connecting shaft coincides with the rotation axis of the driven crank, one end of the connecting shaft is connected to the fixed end of the driven crank, and the other end of the connecting shaft penetrates through the connecting piece and is connected with the blade.

In a second aspect, the present invention provides an air conditioner, including the air outlet assembly of any one of the foregoing embodiments.

Detailed Description

The air outlet assembly is an important component of the air conditioner. Fig. 1 is a schematic view of a prior art wind sweeping assembly. As shown in fig. 1, the wind sweeping blades 4 'are connected to the base 1' (which may be an air outlet frame) through cranks, and the swinging ends of the cranks are hinged to the connecting rods 5 ', and synchronously swing through the connecting rods 5'. In the existing air outlet assembly, a driving crank 2 ' is required to drive a connecting rod 5 ' to move, and the connecting rod 5 ' drives each driven crank 3 ' to rotate, so that each blade 4 ' synchronously swings. As shown in fig. 1, since the driving crank 2 'and the driven crank 3' are both hinged to the connecting rod 5 ', there is only a degree of freedom in the rotational direction with respect to the connecting rod 5'. In this case, the driving crank 2 'is required to swing in the same height as the driven crank 3', otherwise it is easy to be locked. The length of the arm of force of the driving crank 2 'in the existing air outlet assembly must be the same as that of the driven crank 3', and the extension direction must also be the same, and the rotation direction of the driving crank 2 'must be the same as that of the driven crank 3', and the rotation angle is also completely the same. It can be seen that the structure and installation manner of the driving crank 2 ' are greatly limited by the manner of hinging the swinging end of the driving crank 2 ' with the connecting rod 5 ', and the flexibility is poor.

In order to improve the deficiency of the air outlet assembly in the prior art, the embodiment of the application provides an air outlet assembly, and the arrangement mode of the driving crank is diversified and more flexible by changing the matching mode of the driving crank and the connecting piece. The embodiment of the application also provides an air conditioner comprising the air outlet assembly.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Fig. 2 is a partial schematic view of an air outlet assembly 100 according to an embodiment of the present disclosure; fig. 3 is a schematic view illustrating the air outlet assembly 100 discharging air to the right according to an embodiment of the present disclosure; fig. 4 is a schematic view illustrating the air outlet assembly 100 discharging air to the left according to an embodiment of the present disclosure. As shown in fig. 2 to 4, the air outlet assembly 100 provided in the embodiment of the present application includes a base 110, a driving crank 120, a driven crank 130, a connecting member 140, and a blade 150 disposed on the driven crank 130, where the driving crank 120 and the driven crank 130 both have a fixed end and a swing end, the fixed ends of the driving crank 120 and the driven crank 130 are rotatably connected to the base 110, the blade 150 is fixedly connected to the fixed end of the driven crank 130, and the connecting member 140 is rotatably connected to the swing end of the driven crank 130. The connecting member 140 is provided with a strip-shaped hole 141, and the strip-shaped hole 141 is matched with the swinging end of the driving crank 120, so that when the driving crank 120 drives the driven crank 130 to rotate through the connecting member 140, the swinging end of the driving crank 120 can slide and rotate in the strip-shaped hole 141.

In the present embodiment, the base 110 includes a first mounting portion 111 and a second mounting portion 112, the first mounting portion 111 is strip-shaped and extends along a first direction (i.e., a left-right direction in the drawing), and the second mounting portion 112 is connected to one end of the first mounting portion 111. The driven crank 130 is connected to the first mounting portion 111, and the driving crank 120 is connected to the second mounting portion 112. In this embodiment, the blades 150 connected to the driven cranks 130 are opposite to the air outlet of the air conditioner, and the driving cranks 120 are disposed on one side of the whole driven cranks 130, so as to facilitate the arrangement of a driving member (not shown) for driving the driving cranks 120 to rotate, and prevent the driving member from being located in the middle and corresponding to the air outlet. Also, in the present embodiment, the air outlet assembly 100 includes a plurality of driven cranks 130, the plurality of driven cranks 130 are arranged along the first direction, each driven crank 130 has the same structure (at least the arm length is the same), and the driving crank 120 is disposed on one side of the whole driven crank 130, so that the arrangement of the driving crank 120 different from the structure of the driven cranks 130 is more convenient without damaging the whole array of the driven cranks 130.

In this embodiment, the second mounting portion 112 is strip-shaped, and one end of the second mounting portion 112 is connected to the end of the first mounting portion 111, so that the connecting member 140 is L-shaped. Specifically, the second mounting portion 112 extends toward the inside of the air conditioner such that the driving crank 120 is closer to the inside of the air conditioner than the driven crank 130. Because the blades 150 connected to the driven crank 130 correspond to the air outlet, if the air conditioner is applied to a cylindrical vertical cabinet air conditioner, the second mounting portion 112 is bent toward the inside of the air conditioner to avoid the air conditioner housing, which facilitates the mounting of the driving crank 120 and the driving member. Optionally, the second mounting portion 112 extends in a second direction, the second direction being perpendicular to the first direction.

In the present embodiment, the base 110 may have a bar shape. The fixed end of the driven crank 130 is provided with a connecting shaft, the axis of the connecting shaft coincides with the rotation axis of the driven crank 130, one end of the connecting shaft is connected to the fixed end of the driven crank 130, and the other end of the connecting shaft penetrates through the connecting member 140 along the thickness direction of the base 110 and is connected with the blade 150.

As can be seen from fig. 2 to 4, when the driving crank 120 rotates, the connecting member 140 is pulled to move, and the swinging end of the driven crank 130 is pulled to move by the connecting member 140, so that the driven cranks 130 rotate synchronously. It will be appreciated that the path of movement of the link 140 is the same shape as the path of movement of the swing end of the driven crank 130, both being in the shape of a circular arc and being in the same arc.

In the embodiment of the present application, since the swinging end of the driving crank 120 is engaged with the strip-shaped hole 141 of the connecting member 140, the connecting end of the driving crank 120 can rotate relative to the connecting member 140 and can also translate relative to the connecting member 140. Under the structure, because the swinging end of the driving crank 120 can slide in the strip-shaped hole 141, the length and the extending direction of the arm of force of the driving crank 120 are different from those of the driven crank 130, and the phenomenon that the driving crank 120 is blocked and cannot swing together is not generated. It can be seen that, the air outlet assembly 100 provided in the embodiment of the present application makes the structure and the installation manner of the driving crank 120 have more choices and better flexibility by providing the strip-shaped hole 141 on the connecting member 140.

Specifically, in the present embodiment, the arm length of the driving crank 120 is greater than the arm length of the driven crank 130. It should be understood that the arm length described herein refers to the length of the arm, the arm length of the driving crank 120 refers to the distance between the rotation axis of the fixed end thereof and the position where the swing end contacts the inner wall of the bar-shaped hole 141, and the arm length of the driven crank 130 refers to the distance between the rotation axis of the fixed end of the driven crank 130 and the rotation axis of the swing end (compared to the rotation of the link 140). In this embodiment, the arm length of the driving crank 120 is greater than the arm length of the driven crank 130, so that the driving crank 120 only needs to rotate a small angle, resulting in a large lateral displacement of the swinging end. In this embodiment, the swinging end of the driving crank 120 can be configured to match the width of the strip-shaped hole 141, so that the swinging end of the driving crank 120 cannot move in the width direction of the strip-shaped hole 141 relative to the connecting member 140. Therefore, in the case that the extending direction of the strip-shaped hole 141 is perpendicular to the first direction, the displacement of the swinging end of the driving crank 120 in the transverse direction (corresponding to the first direction in the present embodiment) is always kept consistent with that of the driven crank 130, so that the rotation angle of the driven crank 130 is larger after the driving crank 120 generates a certain rotation angle. Therefore, in certain situations, this embodiment can drive the larger driven crank 130 by a smaller rotation angle of the driving crank 120.

As shown in fig. 2 to 4, each of the driven cranks 130 rotates with the driving crank 120 in a direction opposite to that of the driving crank 120. For example, as shown in fig. 2 to 4, the swing end of the driving crank 120 is closer to the outside of the air outlet than the fixed end, and the swing end of the driven crank 130 is closer to the inside of the air outlet than the fixed end, so that when the driving crank 120 drives the driven crank 130 to rotate, the rotation directions of the two are opposite. As shown in fig. 3, the driven crank 130 rotates counterclockwise while the driving crank 120 rotates clockwise to the first limit position (the swinging end is located at the leftmost position). The swing end of the driving crank 120 has an upward (in the actual situation, toward the inside of the air conditioner) displacement amount while swinging leftward (i.e., toward the first limit position) from the intermediate position, and the swing end of the driven crank 130 has a downward (in the actual situation, toward the outside of the air conditioner) displacement amount while swinging leftward from the intermediate position. Just because of the strip-shaped hole 141, the movable end of the driving crank 120 is allowed to slide in the strip-shaped hole 141, so that the opposite displacement of the swing ends of the driving crank 120 and the driven crank 130 in the second direction can be satisfied. The arrangement of the driving crank 120 and the driven crank 130 in the opposite direction can satisfy the arrangement requirement in the air conditioner in some cases.

In an alternative embodiment, the rotation of the driving crank 120 relative to the base 110 has a first limit position and a second limit position, the rotation angle of the driving crank 120 between the first limit position and the second limit position is 50 ° to 70 °, and the driven crank 130 rotates 100 ° to 120 ° during the rotation of the driving crank 120 from the first limit position to the second limit position. The drive crank 120 in fig. 3 is in a first extreme position and the drive crank 120 in fig. 4 is in a second extreme position. The first limit position and the second limit position may be defined by the rotation range of the driving member, or may be defined by the length of the strip-shaped hole 141, for example, when the driving member rotates to the limit positions, the end surface of the strip-shaped hole 141 abuts against the swinging end of the driving crank 120, so that the driving crank cannot rotate any further. Under the condition that the end face of the strip-shaped hole 141 does not interfere with the driving crank 120, the rotation ratio is adjusted by adjusting the relative length of the force arms of the driving crank 120 and the driven crank 130, so that the rotation range of the driving crank 120 is 50-70 degrees, the corresponding rotation range of the driven crank 130 is 100-120 degrees, and the design requirement of the air conditioner can be better met. In one specific embodiment, the range of rotation of the driving crank 120 may be set to 58 ° and the corresponding range of rotation of the driven crank 130 may be set to 113 °.

In this embodiment, the strip-shaped holes 141 extend in the second direction, and the second direction is perpendicular to the first direction, so that the extending direction of the strip-shaped holes 141 is perpendicular to the arrangement direction of the driven cranks 130, and the force application direction of the driving crank 120 to the connecting member 140 is the same as the connecting line direction of the swinging ends of the driven cranks 130, and is the first direction, which is more favorable for the transmission efficiency. It should be understood that the force applied by the swinging end of the driving crank 120 to the connecting member 140 is always perpendicular to the sidewall of the strip-shaped hole 141, without considering the frictional force.

It is understood that in other embodiments of the present application, the rotational angle orientation of the driving crank 120 may be consistent with the rotational angle orientation of the driven crank 130, i.e. the swinging end of the driving crank 120 is closer to the inside of the air conditioner than the fixed end, so that the rotational directions of the driving crank 120 and the driven crank 130 are consistent all the time.

In addition, the embodiment of the present application provides an air conditioner, including the air outlet assembly 100 in the foregoing embodiment, the air outlet assembly 100 is disposed at an air outlet of the air conditioner, and the air conditioner further includes a driving member, and the driving member is in transmission connection with a fixed end of the driving crank 120 to drive the driving crank 120 to rotate relative to the base 110.

In summary, in the air outlet assembly 100 of the present application, since the swing end of the driving crank 120 is engaged with the strip-shaped hole 141 on the connecting member 140, the connecting end of the driving crank 120 can rotate relative to the connecting member 140, and can also translate relative to the connecting member 140. Under the structure, the arm length and the extending direction of the driving crank 120 are allowed to be different from those of the driven crank 130, and the phenomenon that the driving crank 120 is locked and cannot swing together can not occur, because the swinging end of the driving crank 120 can slide in the strip-shaped hole 141. It can be seen that, the air outlet assembly 100 provided in the embodiment of the present application makes the structure and the installation manner of the driving crank 120 have more choices and better flexibility by providing the strip-shaped hole 141 on the connecting member 140. The air conditioner provided by the embodiment of the application comprises the air outlet assembly 100, and therefore, the air conditioner also has corresponding beneficial effects.
