Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a cabinet air conditioner swing blade structure, a cabinet air conditioner indoor unit, and a cabinet air conditioner. Background Technology

[0002] An air conditioner is a device used to regulate the air conditions in an indoor or enclosed space, such as temperature, humidity, airflow speed, and cleanliness.

[0003] In existing technologies, most cabinet air conditioners use a louvered structure for their air outlets. Each louver is connected to a power mechanism through a transmission structure, which includes a connecting rod and a crank. Each louver is hinged to the connecting rod, and one end of the connecting rod is connected to the power mechanism through the crank. Under the action of the power mechanism, the crank rotates within a certain range around the output shaft of the power mechanism. The crank drives the connecting rod to swing, which in turn causes the angle of each louver to change, thereby changing the air outlet direction of the air conditioner.

[0004] However, in the existing technology, most cranks adopt cantilever cranks. The crank is only connected to the output shaft of the power mechanism in the axial direction of the output shaft. That is, the crank has only one fulcrum in the axial direction of the output shaft of the power mechanism. Therefore, after long-term operation, it is easy to cause friction and wear between the crank and the power mechanism, and the gap increases. As a result, after the torque is transmitted to the swing blade, the motion is discontinuous, which affects the user experience. Utility Model Content

[0005] This utility model provides a cabinet air conditioner swing blade structure, a cabinet air conditioner indoor unit, and a cabinet air conditioner to solve the defect in the prior art where the torque is transmitted to the swing blades after long-term operation and the movement is discontinuous. It achieves precise torque transmission and better meets user needs.

[0006] This utility model provides a cabinet air conditioner swing blade structure, including:

[0007] Multiple oscillating blades are all positioned at the air outlet of the cabinet unit, rotating in the first direction.

[0008] A connecting rod is arranged along a second direction, and the connecting rod is rotatably connected to a plurality of the oscillating blades; the second direction is perpendicular to the first direction;

[0009] The power mechanism and base are located inside the cabinet unit;

[0010] The first crankshaft has one end connected to the output shaft of the power mechanism, and the other end of the first crankshaft is rotatably connected to the base.

[0011] A first rocker arm is disposed on the outer periphery of the first crankshaft, and the first rocker arm is rotatably connected to the connecting rod.

[0012] The cabinet swing blade structure provided by this utility model sets the crank in the prior art as a first crankshaft and a first rocker arm. One end of the first crankshaft is connected to the output shaft of the power mechanism, and the other end of the first crankshaft is rotatably connected to the base. Therefore, the first crankshaft has two support points. When the first crankshaft has been running for a long time, the cantilever structure relative to the first crankshaft can avoid the gap between the first crankshaft and the output shaft of the power mechanism, so that the torque of the power mechanism is transmitted to the swing blade, the movement is continuous, and the user experience is improved.

[0013] According to the cabinet swing blade structure provided by this utility model, the connecting rod is provided with an avoidance groove.

[0014] The above structural design can improve the interference problem between the connecting rod and the first crankshaft when the blade is at its maximum angle.

[0016] Multiple second crankshafts are connected to one end of the multiple oscillating blades respectively;

[0017] Multiple second rocker arms are connected one-to-one with the second crankshaft, and each second rocker arm is rotatably connected to the connecting rod.

[0018] With the above structure, under the action of the power mechanism, the connecting rod drives the second rocker arm to swing, thereby realizing the time switching between the open and closed states of the swing blade.

[0019] According to the cabinet swing blade structure provided by this utility model, the connecting rod is provided with a plurality of connecting holes, and the second rocker arm extends into the corresponding connecting holes.

[0020] With the above structure, the second rocker arm extends into the connecting hole to achieve a rotatable connection between the second rocker arm and the connecting rod. Driven by the power mechanism, the connecting rod drives the second rocker arm to rotate, thereby changing the angle of the swing blade relative to the cabinet, thus enabling the swing blade to switch between the open and closed states.

[0021] According to the cabinet swing blade structure provided by this utility model, the end of the first rocker arm away from the first crank shaft is set in a conical shape; the end of the second rocker arm away from the second crank shaft is set in a conical shape.

[0022] The above structure makes it easier to assemble the first rocker arm with the connecting rod, and the second rocker arm with the connecting rod.

[0023] According to the cabinet swing blade structure provided by this utility model, it also includes a base plate, the base plate is arranged along the second direction, and a plurality of support holes are opened on the base plate, and the second crank shaft passes through the support holes accordingly.

[0024] With the above structural design, the multiple support holes on the base plate can support multiple second crank shafts, so that the torque of the connecting rod on the second crank shaft can be transmitted to the blades as much as possible.

[0025] According to the cabinet swing blade structure provided by this utility model, each of the connecting holes has elongated holes on both sides, and the end of the elongated hole near the connecting hole is connected to the connecting hole.

[0026] The above structural design allows the connecting hole to have good elastic deformation, making it easy for the second rocker arm to be installed inside the connecting hole and achieve a rotating connection.

[0027] According to the cabinet swing blade structure provided by this utility model, a support member is further included, which is disposed in the middle of the swing blade along the second direction, and the support member is rotatably connected to each of the swing blades.

[0028] The above structural design can support multiple blades, ensuring a constant distance between adjacent blades and preventing uneven airflow caused by blade deformation.

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] The following is combined Figures 1-4 This invention describes a cabinet swing blade structure.

[0043] like Figure 1 and Figure 2 As shown, the first aspect of this utility model is to provide a cabinet swing mechanism, including multiple swing blades 1, connecting rods 2, power mechanism 3, base 4, first crankshaft 5 and first rocker arm 6.

[0044] Multiple oscillating blades 1 are rotatably positioned at the air outlet of the cabinet unit 100 along a first direction. The function of the oscillating blades 1 is to adjust the airflow direction to meet different user air supply needs. The first direction can be understood as the horizontal direction when the cabinet unit is normally placed. By rotating the oscillating blades 1, a wide air supply range can be achieved, improving the air supply effect. A connecting rod 2 is positioned along a second direction, and the connecting rod 2 is rotatably connected to the multiple oscillating blades 1; the second direction is perpendicular to the first direction, wherein the first direction and the second direction are as follows: Figure 1 As shown, the second direction can be understood as the height direction when the cabinet is normally placed. The connecting rod 2 acts as a connection and transmission mechanism, transmitting power from one point to multiple swing blades 1 to achieve synchronous rotation.

[0045] The power mechanism 3 and the base 4 are located inside the cabinet 100. The power mechanism 3 is the power source for the rotation of the swing blade 1 and can be a motor or other driving device. The base 4 serves as a support.

[0046] One end of the first crankshaft 5 is connected to the output shaft of the power mechanism 3, and the other end of the first crankshaft 5 is rotatably connected to the base 4; the function of the first crankshaft 5 is to convert the rotational motion of the power mechanism 3 into the swinging motion of the first rocker arm 6, thereby realizing the rotation of the pendulum 1.

[0047] The first rocker arm 6 is disposed on the outer periphery of the first crankshaft 5, and the first rocker arm 6 is rotatably connected to the connecting rod 2. The first rocker arm 6 is connected to the pendulum 1 through the connecting rod 2. When the first crankshaft 5 rotates, the first rocker arm 6 will drive the connecting rod 2 and the pendulum 1 to rotate together.

[0048] The cabinet air conditioner oscillating blade structure provided by this utility model replaces the crank in the prior art with a first crankshaft 5 and a first rocker arm 6. One end of the first crankshaft 5 is connected to the output shaft of the power mechanism 3, and the other end of the first crankshaft 5 is rotatably connected to the base 4. Therefore, the first crankshaft 5 has two support points. When the first crankshaft 5 has been running for a long time, the cantilever structure relative to the first crankshaft 5 results in smooth movement and high transmission efficiency. It can reduce the gap between the first crankshaft 5 and the output shaft of the power mechanism 3, so that the torque of the power mechanism 3 is transmitted to the oscillating blade, resulting in continuous movement and improved user experience. The combined use of the first crankshaft 5 and the first rocker arm 6 can also achieve precise control of the oscillating blade 1 within a certain range, improving the accuracy and comfort of air delivery.

[0049] like Figure 1 and Figure 4 As shown, in a feasible embodiment of this utility model, a clearance groove 7 is provided on the connecting rod 2 to avoid interference between the connecting rod 2 and the first crankshaft 5 when the oscillating blade 1 switches from the closed state to the open state. Specifically, the clearance groove 7 can be set as an arc-shaped clearance groove.

[0050] like Figure 3As shown, in a feasible embodiment of this utility model, it further includes multiple second crankshafts 8 and multiple second rocker arms 9. The second crankshafts 8 are correspondingly connected to one end of multiple pendulum blades 1, ensuring that each pendulum blade 1 can swing independently or synchronously. The multiple second rocker arms 9 are connected one-to-one with the second crankshafts 8, and each second rocker arm 9 is rotatably connected to the connecting rod 2. The second rocker arms 9 can swing relative to the connecting rod 2 at a certain angle, thereby further adjusting the swing angle and speed of the pendulum blades 1.

[0051] When the connecting rod 2 is driven by an external power, it will oscillate back and forth. This oscillation is transmitted to the second crankshaft 8 through the second rocker arm 9, which in turn drives the pendulum 1 to oscillate.

[0052] like Figure 3 and Figure 4 As shown, in a feasible embodiment of this utility model, the connecting rod 2 has multiple connecting holes 21, and the second rocker arm 9 extends into the corresponding connecting holes 21. The connecting holes 21 are provided for a precise and stable connection with the second rocker arm 9. The connecting holes 21 can be evenly distributed along the length of the connecting rod 2. When the second rocker arm 9 extends into the connecting hole 21, the two can fit tightly together, thereby enabling the connecting rod 2 to drive the second rocker arm 9 to rotate.

[0053] In one feasible embodiment of this invention, the end of the first rocker arm 6 furthest from the first crankshaft 5 is conical; the end of the second rocker arm 9 furthest from the second crankshaft 8 is also conical. The conical design gives the distal ends of the first rocker arm 6 and the second rocker arm 9 a gradually tapering shape, which is not only aesthetically pleasing, but also allows the conical tip to be more easily inserted and fitted into the connecting hole 21. During assembly or operation, the conical distal end can serve as a guide structure, helping the first rocker arm 6 or the second rocker arm 9 to be more accurately positioned at the predetermined connection point.

[0054] like Figure 3 As shown, in a feasible embodiment of this utility model, a base plate 10 is further included. The base plate 10 is arranged along the second direction and has multiple support holes. The second crankshaft 8 passes through the support holes. The base plate 10 is parallel to the connecting rod 2 and is located on the side of the connecting rod 2 facing the oscillating blade 1. The base plate 10 provides a support surface for the second crankshaft 8, ensuring that the mechanism can remain smooth and stable during operation, while also maintaining its degree of freedom of rotation and oscillation.

[0055] In one feasible embodiment of this utility model, elongated holes 22 are provided on both sides of each connecting hole 21, and one end of the elongated hole 22 near the connecting hole 21 communicates with the connecting hole 21. Due to the elongation of the elongated hole 22, it has a certain elastic deformation, which makes the second rocker arm 9 easy to install.

[0056] In one feasible embodiment of this utility model, a support member 11 is further included, which is disposed in the middle of the pendulum blade 1 along the second direction, and the support member 11 is rotatably connected to each pendulum blade 1. The provision of the support member 11 helps to enhance the stability of the pendulum blade 1 during rotation and prevents damage or failure caused by excessive swing amplitude or uneven force.

[0057] In summary, the cabinet swing blade structure provided in the first aspect embodiment of this utility model sets the crank in the prior art as a first crankshaft 5 and a first rocker arm 6. One end of the first crankshaft 5 is connected to the output shaft of the power mechanism 3, and the other end of the first crankshaft 5 is rotatably connected to the base 4. Therefore, the first crankshaft 5 has two support points. When the first crankshaft 5 has been running for a long time, the cantilever structure relative to the first crankshaft 5 can prevent the gap between the first crankshaft 5 and the output shaft of the power mechanism 3 from becoming larger, so that the torque of the power mechanism 3 is transmitted to the swing blade 1 and the movement is continuous, thus improving the user experience.

[0058] The second aspect of this utility model is to provide a cabinet-style indoor unit, including any of the cabinet-style swivel structures mentioned above, wherein the cabinet-style swivel structure is disposed at the air outlet of the cabinet-style unit.

[0059] The third aspect of this utility model is to provide a cabinet air conditioner, including any of the cabinet air conditioner louver structures or cabinet indoor units as described above.

[0060] The cabinet indoor unit and cabinet air conditioner provided by this utility model have the various advantages described above because they include the cabinet swing blade structure described above.
