Description

Technical Field

[0001] This application belongs to the field of household appliance technology, specifically relating to a vertical oscillating blade assembly, an indoor air conditioning unit, and an air conditioner. Background Technology

[0002] An air conditioner generally consists of an outdoor unit and an indoor unit. The outdoor unit contains a compressor and a condenser. The compressor compresses the gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. After cooling in the condenser, the gaseous refrigerant becomes a room-temperature, high-pressure liquid refrigerant, which is then transported to the indoor unit through a capillary tube. The indoor unit contains an evaporator and a cross-flow fan. When the liquid refrigerant reaches the evaporator, the sudden increase in space causes it to vaporize and become a low-temperature gaseous refrigerant, thus absorbing a large amount of heat. The cross-flow fan guides indoor air through the evaporator; after heat exchange within the evaporator, the air is blown out of the indoor unit into the environment, thus lowering the ambient temperature.

[0003] In the relevant technical solutions, the air outlet of the indoor unit of the air conditioner is provided with a vertical swing blade assembly for controlling the air outlet direction. The vertical swing blade assembly includes a vertical swing blade, a crank and a motor. The vertical swing blade is detachably connected to one end of the crank, and the other end of the crank is connected to the motor. When the motor is working, it can drive the vertical swing blade to swing left and right in the horizontal direction, thereby adjusting the air outlet direction.

[0004] However, after a period of use, the vertical swivel blades of the indoor air conditioner need to be removed for cleaning. Using the above-mentioned related technologies, the installation and removal of the vertical swivel blades are rather inconvenient. Summary of the Invention

[0037] In related technical solutions, the air conditioner indoor unit has a vertical oscillating blade assembly at the air outlet for controlling the airflow direction. This assembly includes oscillating blades, a crank, and a motor. The oscillating blades are detachably connected to one end of the crank, and the other end of the crank is connected to the motor. When the motor operates, it drives the oscillating blades to swing left and right horizontally, thereby adjusting the airflow direction from the outlet. However, after a period of use, the oscillating blades need to be removed for cleaning. Using the aforementioned technical solutions, the installation and removal of the oscillating blades is rather inconvenient.

[0038] In view of this, the embodiments of this application aim to provide a vertical oscillating blade assembly, an indoor air conditioning unit, and an air conditioner. One end of the vertical oscillating blade is provided with a first sub-connecting portion, and one end of the crank is provided with a second sub-connecting portion. The first sub-connecting portion can abut against the second sub-connecting portion to form a connecting portion. Fasteners are sleeved on the outside of the connecting portion, and the first sub-connecting portion and the second sub-connecting portion are fixedly connected. With the above configuration, when installing the vertical oscillating blade and the crank, the vertical oscillating blade can form a connecting portion by abutting against the second sub-connecting portion on the crank using the first sub-connecting portion, and then the connecting portion is locked and fixed using fasteners, thereby realizing the connection between the vertical oscillating blade and the crank. When disassembling, the first sub-connecting portion and the second sub-connecting portion can be separated from each other simply by removing the fasteners from the connecting portion, thereby facilitating the installation and disassembly of the vertical oscillating blade and the crank.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] Example 1

[0041] Figure 1 This is a simplified structural diagram of a vertical oscillating blade assembly provided in one embodiment of this application; Figure 2 This is a simplified structural diagram of a vertically oriented blade provided in one embodiment of this application; Figure 3 This is a simplified structural diagram of a crank provided in one embodiment of this application; Figure 4 This is a simplified structural diagram of a fastener provided in an embodiment of this application.

[0042] Please refer to Figures 1-4 This embodiment provides a vertical oscillating blade assembly, including:

[0043] The device comprises a oscillating blade 100, a crank 200, and a fastener 300. The oscillating blade 100 extends along a first direction X, and one end of the oscillating blade 100 along the first direction X has a first sub-connecting portion 110. The crank 200 has a second sub-connecting portion 210 at one end along the first direction X. The first sub-connecting portion 110 can abut against the second sub-connecting portion 210 along a second direction Y to form a connecting portion. The fastener 300 is sleeved on the outside of the connecting portion along the second direction Y, thereby fixing the first sub-connecting portion 110 and the second sub-connecting portion 210 together. The first direction X and the second direction Y are perpendicular to each other.

[0044] Specifically, the vertical oscillating blade 100 includes multiple oscillating blades arranged along a first direction X (only one is shown in the figure). These blades are interconnected via connecting rods or other structures, with a certain gap between adjacent blades. Airflow from the indoor unit can pass through this gap, thus changing direction. A first sub-connecting part 110 can be located in the middle of the vertical oscillating blade 100, facilitating the even transmission of power from the crank 200 to the vertical oscillating blade 100. The crank 200 includes two mutually perpendicular drive shafts. One drive shaft connects to a motor to receive power output from the motor, and the other drive shaft connects to the vertical oscillating blade 100 to drive its rotation. A second sub-connecting part 210 is provided on the drive shaft connecting the vertical oscillating blade 100. The second sub-connecting part 210 can abut against the first sub-connecting part 110 to form a connecting part. The connecting part can be detachably connected to a fastener 300, thereby achieving a fixed connection between the vertical oscillating blade 100 and the crank 200.

[0045] With the above configuration, when installing the oscillating blade 100 and the crank 200, the oscillating blade 100 can form a connecting part by abutting the first sub-connecting part 110 and the second sub-connecting part 210 on the crank 200. Then, the connecting part is locked and fixed using fasteners 300, thereby achieving the connection between the oscillating blade 100 and the crank 200. During disassembly, simply removing the fasteners 300 from the connecting part allows the first sub-connecting part 110 and the second sub-connecting part 210 to separate, thus allowing the oscillating blade 100 to be removed. This embodiment facilitates the installation and disassembly of the oscillating blade 100 and the crank 200.

[0046] In one possible implementation, such as Figures 1-3 As shown, in this embodiment, the first sub-connecting portion 110 and the second sub-connecting portion 210 both have a fan-shaped cross-section perpendicular to the first direction X, and the connecting portion has a circular cross-section perpendicular to the first direction X. Preferably, the first sub-connecting portion 110 and the second sub-connecting portion 210 both have a semi-circular cross-section perpendicular to the first direction X, and after the first sub-connecting portion 110 and the second sub-connecting portion 210 abut against each other, a cylindrical connecting portion is formed.

[0047] The outer surface of the connecting part is provided with a first external thread, and the fastener 300 is provided with a through hole 310 with an internal thread, and the fastener 300 is threadedly connected to the connecting part.

[0048] In this embodiment, a first threaded segment is provided on the outer surface of the first sub-connecting part 110, and a second threaded segment is provided on the outer surface of the second sub-connecting part 210. After the first sub-connecting part 110 and the second sub-connecting part 210 abut against each other, the first threaded segment and the second threaded segment are also connected to each other, thereby forming a first external thread. The fastener 300 achieves a threaded connection with the first external thread through the internal thread in the through hole 310, so as to lock and fix the first sub-connecting part 110 and the second sub-connecting part 210.

[0049] When installing the oscillating blade 100 and the crank 200, after the first threaded section on the first sub-connecting part 110 and the second threaded section on the second sub-connecting part 210 are properly engaged, the fastener 300 can be rotated to lock and fix the oscillating blade 100 and the crank 200. When disassembly is required, simply rotate the fastener 300 in the opposite direction to separate the first sub-connecting part 110 and the second sub-connecting part 210 from each other, so that the oscillating blade 100 can be quickly removed.

[0050] Furthermore, in this embodiment, the crank 200 is also provided with a transition portion 220 connected to the second sub-connecting portion 210. The projection of the transition portion 220 in a section perpendicular to the first direction X coincides with the projection of the connecting portion in a section perpendicular to the first direction X; that is, the diameter of the connecting portion formed after the transition portion 220 abuts and engages with the first sub-connecting portion 110 and the second sub-connecting portion 220 is the same. The outer side of the transition portion 220 is provided with a second external thread, and the fastener 300 can be fixed to the outer side of the transition portion 220.

[0051] When it is necessary to disassemble the oscillating blade 100 and the crank 200, the fastener 300 can be rotated to move the fastener 300 from the connecting part to the transition part 220. In this way, the first sub-connecting part 110 and the second sub-connecting part 220 are separated from each other because they are not restricted by the fastener 300, so the oscillating blade 100 can be quickly disassembled. When it is necessary to assemble the oscillating blade 100 and the crank 200, the fastener 300 can be rotated to move the fastener 300 from the transition part 220 to the outside of the connecting part, so as to lock and fix the first sub-connecting part 110 and the second sub-connecting part 220, thereby realizing the connection and fixation between the oscillating blade 100 and the crank 200.

[0052] Furthermore, the transition portion 220 is provided with a blocking member mounting hole at one end near the second sub-connecting portion 210. An elastic member and a blocking member 230 are provided in the blocking member mounting hole. The blocking member 230 is retractably connected to the transition portion 220 through the elastic member.

[0053] In this embodiment, the elastic member has a first state and a second state. When the elastic member is in the first state, it is compressed, causing the blocking member 230 to move towards the blocking member mounting hole, so that the blocking member 230 is received within the blocking member mounting hole; at this time, the fastener 300 can move freely between the transition portion 220 and the connecting portion. When the elastic member is in the second state, the blocking member 230 is at least partially exposed outside the blocking member mounting hole, thereby blocking the movement of the fastener 300. When the elastic element is in the second state, the blocking element 230 has different functions depending on the position of the fastener 300. When the fastener 300 is located on the transition portion 220, the blocking element 230 abuts against the lower end of the fastener 300 to prevent the fastener 300 from falling off the transition portion 220. When the fastener 300 is located on the connecting portion, the blocking element 230 abuts against the upper end of the fastener 300 to clamp and fix the fastener 300 between the swing blade and the blocking element 230, ensuring the stability of the connection between the vertical swing blade 100 and the crank 200.

[0054] In another possible implementation, the fastener 300 of this embodiment can also be a spring clamp, and the inner diameter of the fastener 300 in the free state is smaller than the outer diameter of the connecting part.

[0055] When installing the vertical swing blade 100 and the crank 200, the vertical swing blade 100 can form a connecting part with the second sub-connecting part 210 on the crank 200 by abutting against it through the first sub-connecting part 110. Then, the fastener 300 is spread open, and after the fastener 300 is sleeved on the outside of the connecting part, it is loosened. Thus, the elastic force of the fastener 300 can be used to lock and fix the connecting part, thereby achieving the connection between the vertical swing blade 100 and the crank 200; when disassembling, only the fastener 300 needs to be spread open to be removed from the connecting part, enabling the first sub-connecting part 110 and the second sub-connecting part 210 to be separated from each other, so that the vertical swing blade 100 can be disassembled. This embodiment can also achieve convenient and fast installation and disassembly between the vertical swing blade 100 and the crank 200.

[0056] In other possible embodiments, in order to improve the stability of the connection between the vertical swing blade 100 and the crank 200, the surface of the first sub-connecting part 110 facing the second sub-connecting part 210 of this embodiment is provided with a convex part, and the surface of the second sub-connecting part 210 facing the first sub-connecting part 110 is provided with a concave part. The convex part can be inserted into the concave part, so as to further improve the stability of the connection between the vertical swing blade 100 and the crank 200 by means of the abutting fit between the convex part and the concave part.

[0057] Optionally, the specific structures of the convex part and the concave part of this embodiment can be set according to needs. For example, both the convex part and the concave part extend along the third direction Z, and both the convex part and the concave part are in the shape of a "one" character. Or, both the convex part and the concave part are in the shape of a "cross" character. The convex part includes a first convex part 111 and a second convex part 112 arranged in an intersecting manner. The first convex part 111 extends along the third direction Z, and the second convex part 112 extends along the first direction X; the concave part includes a first concave part 211 and a second concave part 212 arranged in an intersecting manner. The first concave part 211 extends along the third direction Z, and the second concave part 212 extends along the first direction X; wherein, the third direction Z is perpendicular to the first direction X and the second direction Y.

[0058] It should be noted that only two different structures of the convex part and the concave part are shown above. Those skilled in the art can select the appropriate shapes of the convex part and the concave part according to actual needs. For example, the convex part and the concave part can also be in the shapes of a "rice" character, a "Z" character, a "T" character, etc. This embodiment does not make further limitations on this.

[0059] In summary, in this embodiment, when installing the oscillating blade 100 and the crank 200, the oscillating blade 100 can form a connecting part by abutting the first sub-connecting part 110 and the second sub-connecting part 210 on the crank 200. Then, the connecting part is locked and fixed using fasteners 300, thereby achieving the connection between the oscillating blade 100 and the crank 200. During disassembly, simply removing the fasteners 300 from the connecting part allows the first sub-connecting part 110 and the second sub-connecting part 210 to separate, thus allowing the oscillating blade 100 to be removed. This embodiment facilitates the installation and disassembly of the oscillating blade 100 and the crank 200.
