Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air sweeping component with foldable blades and an air conditioner having the same. Background Art

[0002] With the gradual improvement of living standards, household split wall-mounted air conditioners are becoming increasingly popular. Wall-mounted air conditioners supply air to the room through air ducts and air sweeping components. When the surface temperature is lower than the dew point temperature of the environment for a long time and is transferred to the surrounding air to reduce the air to the dew point temperature, condensation will be generated on the surface of the air duct. Condensation can easily absorb dust, causing it to accumulate in the air duct and cause bacteria to grow. In this case, using air conditioning can easily pollute the indoor air. In addition, the space is relatively closed when in use, and the air circulation is poor, which can easily affect the health of users.

[0003] Taking the above factors into consideration, it is necessary to keep the air duct clean, so the air duct needs to be cleaned regularly. The current split wall-mounted air conditioner often uses the up and down swinging of the air guide door for up and down air outlet, and the left and right air sweeping is mostly achieved by the swinging of the air sweeping blades (multiple groups of assemblies). Due to the obstruction of the air sweeping blades, the air duct behind the air sweeping blades cannot be cleaned. At the same time, since the air sweeping mechanism is provided with left and right air sweeping motors, it cannot be placed on a component that can be automatically separated. If the air sweeping component is disassembled for cleaning, the user must disconnect the wiring and then reconnect the motor wires after cleaning. This operation requires the user to have certain electrical knowledge and hands-on ability. In addition, even if the disassembly is successful, attention must be paid to the waterproof problem of the air sweeping motor during cleaning. These problems make it more difficult to disassemble the air sweeping component for cleaning. Summary of the invention

[0004] The problem solved by the invention is that the wind sweeping component of the indoor unit of the wall-mounted air conditioner is not easy to disassemble and is difficult to clean.

[0005] In order to solve the above problems, the present invention provides a wind sweeping assembly with foldable blades, which can easily and effectively clean the air duct without disassembling the wind sweeping assembly. It mainly includes: a bottom plate for carrying the wind sweeping assembly, wind sweeping blades, the wind sweeping blades are arranged on the bottom plate through a connecting portion, a transmission rod, the transmission rod is used to drive all the wind sweeping blades in the wind sweeping assembly to swing synchronously, and a driving mechanism is used to drive the transmission rod to swing. A folding mechanism is arranged between the wind sweeping blade and the connecting portion, and the wind sweeping blade is foldably arranged on the bottom plate through the folding mechanism, so that sufficient operating space can be left when cleaning the air duct.

[0006] Furthermore, the folding mechanism includes a folding part, a positioning part, a fixing part and a fixing structure. When the wind sweeping is working, the positioning part and the fixing part are used to position the working position of the wind sweeping blade, and the fixing structure is used to fix the wind sweeping blade in the working position. When the blade is folded, the wind sweeping blade can be rotated and folded around the folding part.

[0007] Furthermore, the fixing structure includes at least one group of clamping columns and clamping holes, and the clamping columns and the clamping holes are engaged with each other to fix the wind sweeping blades.

[0008] Furthermore, the folding portion is arranged on one side of the bottom surface of the wind sweeping blade, and the positioning portion is arranged on the other side of the bottom surface of the wind sweeping blade opposite to the folding portion. When folding, the wind sweeping blade rotates and folds around the folding portion, and the positioning portion rotates with the wind sweeping blade. When returning to the working position, the wind sweeping blade rotates around the folding portion.

[0009] Furthermore, the fixing portion is arranged at the upper end of the connecting portion to assist the positioning portion in positioning or to support the folding portion.

[0010] Furthermore, the connecting part includes a first connecting part, a second connecting part is provided at the lower end of the first connecting part, a connecting support part is provided in the middle section of the second connecting part, a third connecting part is provided at the lower end of the second connecting part, the lower surface of the first connecting part is used to cooperate with the upper surface of the cavity, the second connecting part is used to cooperate with the bottom plate and the arc-shaped groove on the cavity, and the upper surface of the third connecting part is used to cooperate with the lower surface of the bottom plate to fix the wind sweeping blade.

[0011] Furthermore, the connection portion is rotatably connected to the transmission rod via the connection support portion, and the transmission rod is disposed on the connection portion so as not to interfere with the folding of the wind sweeping blades.

[0012] Furthermore, a connecting hole is provided on the connecting support portion, and a transmission rod connecting hole is correspondingly provided on the transmission rod, and the two are rotationally connected via a pin shaft.

[0013] Furthermore, a cavity is provided on the bottom plate, and the cavity is installed in cooperation with the lower surface of the first connecting part and the upper surface of the third connecting part on the connecting part, and the connecting support part and the transmission rod are covered therein. The cavity is used to seal and protect structures that are difficult to clean, such as the transmission rod and the connecting support part, to avoid dust accumulation and reduce the difficulty of cleaning.

[0014] Preferably, the air conditioner comprises an air sweeping component structure as described in any one of the above.

[0015] Compared with the prior art, the present invention has the following advantages: the present invention provides a wind sweeping assembly with foldable blades, which can be folded and laid down when the air duct needs to be cleaned, providing sufficient cleaning space and simple operation. In addition, a structure in which a cavity covers a transmission rod is provided, so that the blades do not interfere with the transmission rod when they are laid down, and the synchronous swinging of the wind sweeping blades between the wind sweeping assembly is not affected. At the same time, the transmission rod and the connecting support parts that are difficult to clean are sealed and protected to avoid dust accumulation, thereby reducing the difficulty of cleaning.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] A wind sweeping assembly with foldable blades according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Embodiment 1

[0037] like Figure 1-Figure 2 As shown, a specific embodiment 1 of the present invention describes a wind sweeping assembly with foldable blades, which mainly includes: a base plate 1, wind sweeping blades 3, a transmission rod 6, a driving mechanism, a folding mechanism 4, and a connecting part 5.

[0038] Among them, the base plate 1 is arranged at the bottom of the wind sweeping assembly, which is used to support the entire wind sweeping assembly, and a cavity 2 is arranged on it. The cavity 2 is adapted to be installed with the base plate 1 and the connecting part 5. A wind sweeping blade 3 is arranged on the upper part of the connecting part 5, and a folding mechanism 4 is arranged between the wind sweeping blade 3 and the connecting part 5. The wind sweeping blade 3 can be folded on the base plate 1 through the folding mechanism 4. When cleaning the air duct, the wind sweeping blade 3 can be folded to make enough operating space, and a driving mechanism is used to drive the transmission rod 6 to swing; the transmission rod 6 is used to drive all the wind sweeping blades 3 in the wind sweeping assembly to swing synchronously.

[0039] like Figure 3-Figure 7 As shown, a folding portion 7 is provided on one side of the bottom of the wind sweeping blade 3, and a positioning portion 8 is provided on the other side of the bottom surface of the wind sweeping blade 3 corresponding to the folding portion 7. A clamping column 9 is provided on the side of the positioning portion 8 facing the folding portion 7. The wind sweeping blade 3, the folding portion 7, the positioning portion 8 and the clamping column 9 are integrally formed.

[0040] A fixing portion 11 is provided at the upper end of the connecting portion 5, and the fixing portion 11 is connected to the lower portion of the folding portion 7. A groove is provided on the surface of the fixing portion 11 facing the positioning portion 8, and a clamping hole 10 is provided on the bottom surface of the groove. The clamping hole 10 is clamped with the clamping column 9 on the positioning portion 8 to form a fixing structure 21 for fixing the positioning portion 8 and the fixing portion 11. The positions of the clamping column 9 and the clamping hole 10 can be interchanged to keep the wind sweeping blade 3 in the working position. At the same time, a slightly protruding clamping edge 12 is provided on the edge of the groove for clamping the positioning portion 8 to assist in fixing the wind sweeping blade 3.

[0041] The connecting portion 5 includes: a first connecting portion 13, the lower surface of which is adapted to be installed with the upper surface of the cavity 2, and a second connecting portion 14 is provided at its lower end, and the second connecting portion 14 is adapted to be installed with the arc-shaped groove 19 provided on the cavity 2 and the bottom plate 1. In addition, a connecting support portion 16 is integrally formed on the second connecting portion 14, and a connecting hole 18 is opened on the connecting support portion 16. The connecting hole 18 is of the same specification as the transmission rod connecting hole 20 on the transmission rod 6, and the transmission rod 6 is connected to the connecting support portion 16 through a pin 22. The transmission rod 6 is provided with transmission rod connecting holes 20 equal in number to the wind sweeping blades 3, so that all the wind sweeping blades 3 of a wind sweeping assembly can be connected, and a gasket 17 is provided between the connecting portion of the transmission rod 6 and the connecting support portion 16. A third connecting portion 15 is provided at the lower part of the second connecting portion 14, and the upper surface of the third connecting portion 15 is adapted to be installed with the bottom surface of the bottom plate 1.

[0042] In the design of traditional wind sweeping components, the connection between the transmission rod 6 and the wind sweeping blade 3 often produces dead corners that are difficult to clean. These dead corners are prone to dust accumulation and breeding of bacteria, thereby polluting the indoor air and posing hidden dangers to human health. In the present invention, through the provision of the cavity 2, the connection between the transmission rod 6 and the connecting support 16 is completely covered, thereby avoiding dust accumulation in this part. At the same time, since there is no need to provide a connection structure between the wind sweeping blade 3 and the transmission rod 6, the structure of the wind sweeping blade 3 is simplified, and the outer surface structure of the cavity 2 is simple and easy to clean, which can achieve a better cleaning effect than the original wind sweeping component.

[0043] When the wind sweeping assembly performs left and right wind sweeping work, the driving mechanism drives the transmission rod 6 to swing left and right, the transmission rod 6 drives the remaining connection parts 5 to swing left and right, and the connection parts 5 drive all the wind sweeping blades 3 on the wind sweeping assembly to swing synchronously. At this time, the state of the wind sweeping blades 3 is as follows: Figure 1 As shown, the bottom plate 1 is perpendicular to the bottom plate 1. When the user needs to clean the air duct behind the wind sweeping assembly, the wind sweeping blade 3 needs to be folded due to the obstruction of the wind sweeping blade 3. At this time, the user only needs to gently push the wind sweeping blade 3 in the direction of the bottom plate 1 to separate the clamping column 9 and the clamping hole 10 in the fixing structure 21. The wind sweeping blade 3 drives the positioning part 8 to fold around the folding part 7. At this time, the wind sweeping blade 3 is in the state as shown in FIG. Figure 8 As shown, the folding continues until the upper end of the wind sweeping blade 3 contacts the upper surface of the cavity 2. At this time, the wind sweeping assembly is in the state of Fig. 9 As shown, sufficient cleaning space can be left to facilitate users to carry out comprehensive cleaning. When cleaning is completed, lift the sweeping blade 3, and the sweeping blade 3 drives the positioning portion 8 to rotate around the folding portion 7. When the positioning portion 8 fits with the groove on the fixing portion 11 and the clamping column 9 is clamped with the clamping hole 10, the sweeping blade 3 is perpendicular to the bottom plate 1. At this time, the sweeping blade 3 returns to the working position and cleaning is completed.

The wind sweeping blade 3 can be folded on the base plate 1 through the folding mechanism 4. When cleaning the air duct, the wind sweeping blade 3 can be folded to make enough operating space.

[0047] like Figure 12-14As shown, a rotating shaft 25 is provided on one side of the bottom of the wind sweeping blade 3, and the rotating shaft 25 is equivalent to the folding portion 7 in the claim, and a positioning portion 8 is provided on the other side thereof, and the positioning portion 8 includes a reinforcing portion 23 and a positioning plate 24, and a clamping hole 10 is provided on the positioning plate 24, and the wind sweeping blade 3, the rotating shaft 25 and the positioning portion 8 are integrally formed.

[0048] A fixing portion 11 is disposed at the upper end of the connecting portion 5 . A rotating shaft mounting hole 26 is disposed on the fixing portion 11 . The rotating shaft 25 is connected to the fixing portion 11 through the rotating shaft mounting hole 26 .

[0049] The connecting portion 5 includes: a first connecting portion 13, the lower surface of the first connecting portion 13 is adapted to be installed with the upper surface of the cavity 2, a clamping column 9 is provided on the upper surface of the first connecting portion 13, the clamping column 9 is engaged with the clamping hole 10 on the positioning plate 24, and is used to fix the positioning portion 8 to keep the wind sweeping blade 3 in the working position, the positions of the clamping column 9 and the clamping hole 10 are interchangeable, a second connecting portion 14 is provided at the lower end of the first connecting portion 13, the second connecting portion 14 is adapted to be installed with the arc groove 19 provided on the cavity 2 and the bottom plate 1, and in addition, a connecting portion 14 is integrally formed with A connecting support portion 16 is provided with a connecting hole 18, and the connecting hole 18 is of the same specification as the transmission rod connecting hole 20 on the transmission rod 6. The transmission rod 6 is connected to the connecting support portion 16 through a pin 22. The transmission rod 6 is provided with transmission rod connecting holes 20 equal in number to the wind sweeping blades 3, so that all the wind sweeping blades 3 of a wind sweeping assembly can be connected. A gasket 17 is provided between the connecting portion of the transmission rod 6 and the connecting support portion 16. A third connecting portion 15 is provided at the lower portion of the second connecting portion 14, and the upper surface of the third connecting portion 15 is adapted to be installed with the bottom surface of the base plate 1.

[0050] This embodiment adopts the same cavity design as that in the first embodiment to achieve a better cleaning effect than the original air sweeping assembly.

[0051] When the wind sweeping assembly performs left and right wind sweeping work, the driving mechanism drives the transmission rod 6 to swing left and right, the transmission rod 6 drives the remaining connecting parts 5 to swing left and right, and the connecting parts 5 drive all the wind sweeping blades 3 on the wind sweeping assembly to swing synchronously. At this time, the state of the wind sweeping blades 3 is as follows: Figure 1 As shown, the bottom plate 1 is perpendicular to the bottom plate 1. When the user needs to clean the air duct behind the wind sweeping assembly, the wind sweeping blade 3 needs to be folded due to the obstruction of the wind sweeping blade 3. At this time, the user only needs to gently push the wind sweeping blade 3 in the direction of the bottom plate 1 to separate the clamping column 9 and the clamping hole 10 in the fixing structure 21. The wind sweeping blade 3 drives the reinforcement part 23 and the positioning plate 24 to rotate around the rotation axis 25 and fall down. At this time, the wind sweeping blade 3 is in the state as shown in FIG. Fig.15 As shown, the folding continues until the upper end of the wind sweeping blade 3 contacts the upper surface of the cavity 2. At this time, the wind sweeping assembly is in the state of Fig.16 As shown, the user can easily clean the air duct behind the wind sweeping component. When cleaning is completed, lift the wind sweeping blade 3, and the wind sweeping blade 3 drives the reinforcement part 23 and the positioning plate 24 to rotate around the rotating shaft 25. When the positioning plate 24 is in contact with the upper surface of the first connecting part 13 and the clamping column 9 is engaged with the clamping hole 10, the wind sweeping blade 3 is perpendicular to the bottom plate 1. At this time, the wind sweeping blade 3 returns to the working position and cleaning is completed.
