Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air sweeping structure and an air conditioner. Background Art

[0002] The current air sweeping structure of the air conditioner indoor unit is mostly an active blade that drives multiple driven blades to deflect synchronously through a connecting rod to achieve air sweeping. The active blade is installed on the base. The active blade can be divided into automatic and manual according to the drive type. During manual air sweeping, the active blade is moved by manpower, and the active blade and the base are limited by grooves and convex bulges to achieve a specific air sweeping angle. During automatic air sweeping, the active blade is driven to rotate by a motor, and there is no rotation limiting structure between the active blade and the base. It can be seen that the connection structure between the active blade and the base in manual air sweeping mode and automatic air sweeping mode is different. Therefore, the same model cannot share manual air sweeping and automatic air sweeping functions. Summary of the Invention

[0003] The problem solved by the present invention is that the automatic air sweeping function and the manual air sweeping function of the existing air conditioner cannot coexist.

[0004] To solve the above problems, the present invention proposes an air sweeping structure for sweeping air in an air conditioner indoor unit, comprising:

[0005] An active wind-sweeping blade comprises a blade body and a first rotating shaft connected to the blade body at one end, wherein the first rotating shaft is provided with two convex hulls at unequal distances from the shaft end, and one of the convex hulls is provided with a convex rib;

[0006] The base comprises a sleeve and two partitions spaced apart in the sleeve, wherein the partitions are provided with a through hole for the first rotating shaft to pass through and a mounting notch for the convex bulge to pass through, and one of the partitions is provided with a plurality of grooves;

[0007] The first rotating shaft rotates and moves axially in the through hole so that the air sweeping structure switches between the automatic air sweeping mode and the manual air sweeping mode.

[0008] In manual air sweeping mode, the two partitions are clamped between the two convex ridges, and the convex ribs are stuck in the grooves;

[0009] In the automatic air sweeping mode, the convex bump without ribs rotates around the first rotation axis between the two partitions.

[0010] The wind sweeping structure of the embodiment of the present invention only requires an active wind sweeping blade and a base to rotate and move axially in the through hole through the first rotating shaft to enable the wind sweeping structure to switch between automatic wind sweeping mode and manual wind sweeping mode, thereby realizing the coexistence of manual wind sweeping and automatic wind sweeping functions on the same model. The switching operation is convenient and quick, and the wind sweeping structure is simple and the manufacturing cost is low.

[0011] Furthermore, the plurality of grooves are distributed on the partition in a fan shape with the through hole as the center.

[0012] In this technical solution, the convex rib is inserted into the grooves at different positions in the fan shape to enable the air conditioner to sweep air in different directions. When manually sweeping the air, the active blade rotates the convex rib around the first rotating axis under human power. In order to ensure that the convex rib can be inserted into the grooves at different positions to achieve sweeping at a specific angle in the manual sweeping mode, multiple grooves should be distributed in a fan shape on the partition with the through hole as the center.

[0013] Furthermore, the convex rib is located on a side of the convex ridge away from the blade body and facing the blade body.

[0014] In this technical solution, the side of the bulge away from the blade body facing the blade body is in close contact with the lower surface of the partition away from the blade body during manual sweeping. Therefore, the groove is provided on the lower surface of the partition away from the blade body, and the rib is provided on the side of the bulge away from the blade body facing the blade body so that the rib can be stuck in the groove, thereby realizing sweeping at a specific angle in the manual sweeping mode.

[0015] Furthermore, the widths of the mounting notches on the two partitions are different, and the width of the mounting notch on the partition with the groove is smaller;

[0016] The two convex hulls have different widths, and the convex hull with the convex rib has a smaller width;

[0017] The convex bumps with ribs can pass through the installation notches on the two partitions, while the convex bumps without ribs can only pass through the installation notches on the partitions without grooves.

[0018] In this technical solution, the bulge with ribs can pass through the installation notches on the two partitions to facilitate the assembly and disassembly of the first rotating shaft and the sleeve, and the bulge without ribs can only pass through the installation notches on the partition without grooves to prevent the bulge from getting stuck in the installation notches in the automatic wind sweeping mode and affecting the normal operation of the automatic wind sweeping. Because the groove is located on the lower surface of the partition away from the blade body, the rib is located on the side of the bulge facing the blade body away from the blade body. In order to avoid the bulge close to the blade body in the automatic wind sweeping mode from falling into the installation notch and affecting the normal operation of the automatic wind sweeping, the width of the installation notch on the partition away from the blade body should be smaller than the width of the bulge close to the blade body, so that the bulge will not get stuck in the installation notch in the automatic wind sweeping mode and affect the normal operation of the automatic wind sweeping, and it is also convenient for the conversion between manual wind sweeping and automatic wind sweeping modes.

[0019] Furthermore, the convex rib is located on a side of the convex ridge close to the blade body that faces away from the blade body.

[0020] In this technical solution, the side of the bulge close to the blade body that faces away from the blade body is in close contact with the upper surface of the partition close to the blade body during manual sweeping. Therefore, the groove is provided on the upper surface of the partition close to the blade body, and the rib is provided on the side of the bulge close to the blade body that faces away from the blade body so that the rib can be stuck in the groove, thereby realizing sweeping at a specific angle in the manual sweeping mode.

[0021] Furthermore, the widths of the two convex hulls are different, and the width of the convex hull provided with the convex rib is larger;

[0022] The convex bulge with convex ribs cannot penetrate the installation notches on the two partitions, while the convex bulge without convex ribs can penetrate the installation notches on the two partitions.

[0023] In this technical solution, the bulge without ribs can pass through the installation notches on the two partitions to facilitate the assembly and disassembly of the first rotating shaft and the sleeve. The bulge with ribs cannot pass through the installation notches on the two partitions to prevent the bulge from getting stuck in the installation notch in the manual sweeping mode and affecting the normal operation of the manual sweeping. Because the groove is located on the upper surface of the partition close to the blade body, the rib is located on the side of the bulge close to the blade body facing away from the blade body. In order to avoid the bulge close to the blade body falling into the installation notch in the manual sweeping mode and affecting the normal operation of the manual sweeping, the width of the installation notch on the partition close to the blade body should be smaller than the width of the bulge close to the blade body. In this way, the bulge will not get stuck in the installation notch in the manual sweeping mode and affect the normal operation of the manual sweeping. Moreover, this design can also prevent the bulge with ribs from getting stuck in the installation notch on the partition close to the blade body during the conversion between the manual sweeping mode and the automatic sweeping mode, thereby facilitating the conversion between the manual sweeping mode and the automatic sweeping mode.

[0024] Furthermore, the angle formed by the projections of the two convex hulls on the plane perpendicular to the axis of the first rotating shaft relative to the axis of the first rotating shaft is not equal to the angle formed by the projections of the two mounting notches on the plane perpendicular to the axis of the through hole relative to the axis of the through hole.

[0025] In this technical solution, the angle formed by the projections of the two bulges on the surface perpendicular to the axis of the first rotating shaft relative to the axis of the first rotating shaft is not equal to the angle formed by the projections of the two mounting notches on the surface perpendicular to the axis of the through hole relative to the axis of the through hole, so that the two bulges will not appear directly above or below the mounting notches on the two partitions at the same time, that is, at the same time, only one bulge is located directly above or below the mounting notch, avoiding one bulge penetrating one of the mounting notches and driving the other bulge into the other mounting notch, thereby facilitating the switching from automatic air sweeping to manual air sweeping.

[0026] Furthermore, a second rotating shaft is provided on the blade body, and the wind sweeping structure also includes a connecting rod and a plurality of driven blades, and the plurality of driven blades are connected to the second rotating shaft via the connecting rod.

[0027] In this technical solution, the active wind-sweeping blade drives multiple driven blades to deflect synchronously through the connecting rod to achieve wind sweeping.

[0028] Furthermore, two mounting positions are provided on the second rotating shaft along the axial direction, wherein one mounting position is used to connect with the connecting rod in the manual air sweeping mode, and the other mounting position is used to connect with the connecting rod in the automatic air sweeping mode.

[0029] In this technical solution, the design of the two mounting positions does not affect the active sweeping blade driving multiple driven blades to synchronously deflect through the connecting rod to achieve sweeping after switching between manual sweeping and automatic sweeping modes.

[0030] In addition, the present invention also provides an air conditioner, including an indoor unit, wherein the indoor unit has the aforementioned air sweeping structure.

[0031] In this technical solution, the automatic air sweeping and manual air sweeping of the indoor unit of the air conditioner with the aforementioned air sweeping structure can coexist, enriching the functions of the air conditioner.

[0032] Beneficial effects: The technical solution of the present application can realize the coexistence of manual and automatic air sweeping on the same model by adopting two matching connection methods between an active air sweeping blade and a base, and the manual and automatic air sweeping modes can be converted to each other. The conversion operation is convenient and fast, the air sweeping structure is simple, and the manufacturing cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The present invention proposes a sweeping structure, which enables the air conditioner indoor unit to freely switch between automatic sweeping and manual sweeping, solving the problem that automatic sweeping and manual sweeping of existing air conditioners cannot coexist. Moreover, it can realize the coexistence and mutual conversion of manual and automatic sweeping on the same model by adopting two different matching connection methods of an active sweeping blade and a base 3. The conversion operation is convenient and fast, the sweeping structure is simple, and the cost is low.

[0050] The wind sweeping structure of the present invention is described in detail below with reference to the accompanying drawings.

[0051] Reference Figures 1-8 As shown, in one embodiment of the invention, the wind sweeping structure includes active wind sweeping blades and a base 3, as shown in FIG. Figure 1 and Figure 2 As shown, the active wind-sweeping blade includes a blade body 1 and a first rotating shaft 2 connected to the blade body 1 at the upper end. The blade body 1 is provided with a second rotating shaft 11 for connecting a connecting rod. Usually, one end of the connecting rod is connected to the active wind-sweeping blade and the other end is connected to multiple driven wind-sweeping blades. The active wind-sweeping blade drives the driven wind-sweeping blades to deflect synchronously together through the connecting rod to achieve wind sweeping.

[0052] In this embodiment, if Figure 1 and Figure 2 As shown, the first rotating shaft 2 is provided with unequal distances to the shaft end (i.e. Figure 1 The two convex hulls are of different heights and are respectively referred to as the first convex hull 22 and the second convex hull 21. The upper surface of the first convex hull 22 is provided with a rib 23, and the rib 23 is fixedly connected to the first convex hull 22. Preferably, the two are integrally provided, such as Figure 5As shown, the upper surface of the first convex hump 22 is in close contact with the lower surface of the second partition 34 during manual sweeping. Therefore, the groove 35 is provided on the lower surface of the second partition 34, and the rib 23 is provided on the upper surface of the first convex hump 22 so that the rib 23 can be stuck in the groove 35, thereby realizing sweeping at a specific angle in the manual sweeping mode. Of course, in other embodiments, the rib 23 can also be provided on the lower surface of the second convex hump 21.

[0053] In this embodiment, if Figure 3 and Figure 4 As shown, the base 3 includes a sleeve 31 and two partitions arranged in the sleeve 31. The two partitions are fixedly connected to the inner wall of the sleeve 31. The two partitions are respectively recorded as a first partition 33 and a second partition 34. Both partitions are provided with a through hole 39 for the first rotating shaft 2 to pass through and a mounting notch for the convex hull to pass through. Usually, the aperture of the through hole 39 is equal to the diameter of the first rotating shaft 2, so as to limit the first rotating shaft 2 to only rotate and move axially in the through hole 39. Figure 5-Figure 8 As shown, the first rotating shaft 2 can pass through the through hole 39 and rotate in the through hole 39. Figure 3 and Figure 4 As shown, the mounting notch on the first partition 33 is a first mounting notch 37 , and the mounting notch on the second partition 34 is a second mounting notch 36 . The mounting notches communicate with the upper and lower surfaces of the partitions, and one end of the mounting notch communicates with the through hole 39 .

[0054] In this embodiment, the base 3 further includes a mounting plate 32 fixedly mounted on the outside of the sleeve 31. The presence of the mounting plate 32 facilitates the installation of the air sweeping mechanism into the indoor unit of the air conditioner.

[0055] In this embodiment, if Figure 5 and Figure 7 As shown, the two partitions are spaced apart, and the convex hull moves downward through the first mounting notch 37 and enters between the two partitions, and rotates around the first rotating shaft 2 between the two partitions to achieve automatic air sweeping. Figure 7 The relative position relationship between the convex hull and the partition in the automatic wind sweeping mode is shown. Figure 7 The second convex bump 21 located between the upper and lower partitions moves upward through the first mounting notch 37 and returns to the upper surface of the first partition 33, and then the first rotating shaft 2 is rotated so that the rib 23 is engaged with the groove 35 to form a Figure 5 Manual air sweeping can be achieved when the matching connection method is shown.

[0056] In this embodiment, preferably, the two partitions are parallel to each other and perpendicular to the central axis of the sleeve 31. Furthermore, the spacing between the two partitions is the same as the thickness of the second bulge 21 to prevent the second bulge 21 from moving up and down between the two partitions and affecting the normal operation of the automatic air sweeping work.

[0057] In this embodiment, if Figure 4 、 Figure 5 and Figure 7 As shown, a plurality of grooves 35 are provided on the lower surface of the second partition 34. The plurality of grooves 35 are distributed in a fan shape with the through hole 39 as the center on the lower surface of the second partition 34. The ribs 23 are inserted into the grooves 35 at different positions in the fan shape to enable the air conditioner to sweep air in different directions.

[0058] In this embodiment, when manually sweeping the air, the active blade causes the rib 23 to rotate around the first rotating shaft 2 under human power. In order to ensure that the rib 23 can be inserted into the grooves 35 at different positions to achieve a specific angle of sweeping in the manual sweeping mode, multiple grooves 35 should be distributed in a fan shape on the partition with the through hole 39 as the center.

[0059] Of course, in other embodiments, multiple grooves 35 can also be provided on the upper surface of the first partition 33. Similarly, multiple grooves 35 are distributed in a fan shape on the upper surface of the first partition 33 with the through hole 39 as the center. At this time, the rib 23 is located on the lower surface of the second convex bump 21. Because the lower surface of the second convex bump 21 is close to the upper surface of the first partition 33 during manual sweeping, the groove 35 is provided on the upper surface of the first partition 33, and the rib 23 is provided on the lower surface of the second convex bump 21. The rib 23 can be stuck in the groove 35, thereby realizing the manual sweeping mode. The air is swept at a specific angle below. Further, when the first shaft 2 is rotated to make the first convex bump 22 come to the bottom of the second mounting notch 36, the first shaft 2 is moved upward to make the first convex bump 22 pass through the second mounting notch 36 and come between the two partitions to complete the switch from manual sweeping mode to automatic sweeping mode. Conversely, the switch from automatic sweeping mode to manual sweeping mode can be achieved. At this time, the distance between the two partitions is the same as the thickness of the first convex bump 22 to prevent the first convex bump 22 from moving up and down between the two partitions to affect the normal operation of the automatic sweeping work.

[0060] In this embodiment, when the two partitions are clamped between the two convex ridges, the ribs 23 can be clamped into the grooves 35. At this time, the wind sweeping structure is in the manual wind sweeping mode, for example Figure 5 As shown, the upper surface of the first partition 33 is in close contact with the second convex bump 21, and the lower surface of the second partition 34 is in close contact with the first convex bump 22. The first partition 33 and the second partition 34 are clamped by the first convex bump 22 and the second convex bump 21. At this time, the rib 23 is stuck in the groove 35, blocking the first rotating shaft 2 from rotating. Therefore, it is necessary to use your fingers to move the first rotating shaft 2 to change the position of the rib 23 in order to rotate the first rotating shaft 2. That is, by inserting the rib 23 into different grooves 35 to rotate the first rotating shaft 2, it can reach different rotation angles, and then make the sweeping blades deliver air to different angles to achieve manual sweeping. Usually, the sweeping angle of the indoor unit is ±45 degrees, a total of 90 degrees, so the fan angle also needs to be 90°. Figure 4As shown, the spacing between two adjacent grooves 35 can be set according to the wind sweeping fixed angle. Further, in the manual wind sweeping mode, the rib 23 rotates within a 90° fan-shaped area. Accordingly, the rotation angle of the first rotating shaft 2 and the first convex hull 22 and the second convex hull 21 thereon is also ±45 degrees, a total of 90 degrees. Figure 6 shown.

[0061] When assembling the wind sweeping structure, Figure 5 As shown, first pass the first shaft 2 through the first partition 33 from top to bottom, and at the same time, the first protrusion 22 passes through the first mounting notch 37, and then rotate the first shaft 2 so that the first protrusion 22 rotates between the two partitions to just above the second mounting notch 36, and then continue to move the first shaft 2 downward so that the first protrusion 22 passes through the second mounting notch 36. At this time, the second protrusion 21 is still located above the first partition 33, and then the first shaft 2 is rotated so that the rib 23 is engaged in the slot to complete the assembly, and the wind sweeping structure is in manual wind sweeping mode.

[0062] In this embodiment, in order to avoid the first convex bump 22 driving the second convex bump 21 to enter the first mounting notch 37 during the process of passing through the second mounting notch 36, affecting the subsequent rotation of the first rotating shaft 2 so that the rib 23 is engaged in the slot to complete the assembly, the angle formed by the projections of the two convex bumps on the surface perpendicular to the axis of the first rotating shaft 2 relative to the axis of the first rotating shaft 2 is not equal to the angle formed by the projections of the two mounting notches on the surface perpendicular to the axis of the through hole 39 relative to the axis of the through hole 39. This design can prevent the two convex bumps from appearing directly above or below the mounting notches on the two partitions at the same time, that is, at the same time, only one convex bump is located directly above or below the mounting notch, avoiding one convex bump driving the other convex bump into the other mounting notch when passing through one of the mounting notches, facilitating the assembly of the wind sweeping structure and the rapid switching from automatic wind sweeping to manual wind sweeping. The switching operation is simple, convenient and fast, and the wind sweeping structure is simple and the manufacturing cost is low.

[0063] In this embodiment, if Figure 5 As shown, when the first shaft 2 is rotated further to rotate the second convex bump 21 to the top of the first mounting notch 37, the second convex bump 21 can move downward along with the first shaft 2 to pass through the first mounting notch 37 and enter between the two partitions, as shown in FIG. Figure 7 As shown, at this time, the rib 23 moves downward and separates from the groove 35, and the first shaft 2 can rotate under the drive of the motor to realize automatic wind sweeping, and the wind sweeping angle is still ±45 degrees. Figure 8 shown.

[0064] Furthermore, in this embodiment, the width of the first mounting notch 37 is greater than the width of the second mounting notch 36, and the width of the second protrusion 21 is greater than the width of the first protrusion 22. The first protrusion 22 can pass through the mounting notches on the two partitions, and the second protrusion 21 can only pass through the first mounting notch 37. This design is for the convenience of assembling and disassembling the first rotating shaft 2 and the sleeve 31, and for preventing the second protrusion 21 from getting stuck in the second mounting notch 36 in the automatic sweeping mode and affecting the normal operation of the automatic sweeping mode. Third, it is to avoid the second protrusion 21 passing through the second mounting notch 36 and falling to the bottom of the second partition 34 during the switching operation between the manual sweeping mode and the automatic sweeping mode, affecting the switching efficiency, so as to facilitate the quick and efficient completion of the switching between the manual sweeping mode and the automatic sweeping mode. The switching operation is simple, convenient and fast, and the sweeping structure is simple and the manufacturing cost is low.

[0065] Of course, in other embodiments, if the rib 23 is located on the lower surface of the second bulge 21, and multiple grooves 35 are provided on the upper surface of the first partition 33, then the width of the second bulge 21 is greater than the width of the first bulge 22, and the second bulge 21 cannot pass through the installation notches on the two partitions, while the first bulge 22 can pass through the installation notches on the two partitions. This design is for the convenience of assembly and disassembly of the first rotating shaft 2 and the sleeve 31, and for the prevention of the second bulge 21 from passing through the first installation notch 37 and falling between the first partition 33 and the second partition 34 during the switching operation between the manual sweeping mode and the automatic sweeping mode, thereby affecting the switching from the manual sweeping mode to the automatic sweeping mode, thereby ensuring the quick and efficient completion of the switching between the manual sweeping mode and the automatic sweeping mode, and the switching operation is simple, convenient and fast, and the sweeping structure is simple and the manufacturing cost is low.

[0066] In this embodiment, if Figure 1 As shown, two mounting positions for connecting the connecting rod are provided on the second rotating shaft 11 along the axial direction, and the two mounting positions are respectively recorded as the first mounting position 13 and the second mounting position 12. The first mounting position 13 is used to connect with the connecting rod during manual air sweeping, and the second mounting position 12 is used to connect with the connecting rod during automatic air sweeping. In the process of switching between manual air sweeping mode and automatic air sweeping mode, it is necessary to first remove the connection between the connecting rod and the second rotating shaft 11, and then rotate and axially move the first rotating shaft 2. After the air sweeping mode switching operation is completed, the connection between the connecting rod and the second rotating shaft 11 is restored.

[0067] In addition, the present invention also proposes an air conditioner, which has an indoor unit, and the indoor unit has a wind sweeping structure, which is the aforementioned wind sweeping structure. Since this air conditioner adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0068] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
