Detailed Description

In order to further describe the technical means and effects adopted for achieving the preset aim of the invention, the following detailed description refers to the specific implementation, structure, characteristics and effects according to the application of the invention with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, the particular features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.

As shown in fig. 1 to 3, an indoor unit 100 of an air conditioner according to an embodiment of the present invention includes a main body 1 and a blower mechanism 2. The body 1 includes an air outlet 10. The wind sweeping mechanism 2 includes a wind sweeping blade 21 for sweeping wind at the air outlet 10. Wherein, the wind sweeping mechanism 2 can leave the air outlet 10 open.

Wherein the wind sweeping blade 21 has a first state (as shown in fig. 15) of opening the wind outlet 10 and a second state of closing the wind outlet 10 when rotating at the wind outlet 10 to sweep wind. The "let-off" in this patent does not include the case where the wind sweeping blade 21 opens the wind outlet 10 when sweeping the wind at the wind outlet 10 (i.e., does not include the case shown in fig. 15). Mainly because the wind sweeping blade 21 is disposed at the air outlet 10 (generally located inside the air outlet 10), even if the wind sweeping blade 21 is located in the first state of opening the air outlet 10 during wind sweeping, the wind sweeping blade 21 is still located at the air outlet 10, which still causes interference to the cleaning of the air outlet 10 by the external cleaning tool. The term "turn-off" in this patent refers to that the wind sweeping mechanism 2 is entirely removed from the air outlet 10, for example, the wind sweeping mechanism 2 may be completely removed from the air outlet 10 by disassembling, or as shown in fig. 8, the wind sweeping mechanism 2 is entirely turned over to be removed from the air outlet 10.

In the above provided technical scheme, because the air sweeping mechanism 2 can leave the air outlet 10 open, great convenience can be brought to a user for cleaning the air outlet 10 and the air duct.

In order to realize the function that the air sweeping mechanism 2 can leave the air outlet 10, the air sweeping mechanism 2 can be disassembled and assembled relative to the main body 1, so that the air sweeping mechanism 2 can leave the air outlet 10 when being disassembled relative to the main body 1; or the wind sweeping mechanism 2 can move relative to the main body 1 to open the air outlet 10 when moving to the corresponding position. The following is a specific description of the two cases described above.

In the first example, the aforementioned wind sweeping mechanism 2 is detachable with respect to the main body 1, so that the wind sweeping blade 21 is located at the air outlet 10 when mounted on the main body 1, and the wind sweeping blade 21 can be driven to sweep wind; and the air outlet 10 is opened when the main body 1 is detached.

Further, the aforementioned wind sweeping mechanism 2 may include a supporting member 22, the wind sweeping blade 21 is rotatably disposed on the supporting member 22, and the wind sweeping blade 21 may be driven to sweep wind when the wind outlet 10 is located. The wind sweeping mechanism 2 is assembled and disassembled relative to the main body 1 through the supporting piece 22. The support 22 may be detachably connected to the main body 1, such as by a snap fit or a screw.

In the second example, as shown in fig. 1 to 3, the aforementioned wind sweeping mechanism 2 is movable relative to the main body 1, so that the wind sweeping blade 21 is located at the air outlet 10 when moving to the first position, and the wind sweeping blade 21 can be driven to sweep wind; and when moved to the second position, the outlet 10 is opened (as shown in fig. 8).

Further, the aforementioned sweeping mechanism 2 may be moved to the aforementioned first position and second position with respect to the main body 1 by rotating or sliding or the like. The movement of the aforementioned sweeping mechanism 2 to the aforementioned first and second positions with respect to the main body 1 by rotation will be specifically exemplified below.

As shown in fig. 1 to 3, the aforementioned sweeping mechanism 2 may include a support 22. The wind sweeping blade 21 is rotatably provided on the support 22, and the wind sweeping blade 21 can be driven to sweep wind when at the air outlet 10. Wherein the support member 22 is rotatable relative to the main body 1, and the wind sweeping mechanism 2 can be rotated to the aforementioned first and second positions by the support member 22.

Since the support 22 is rotatable relative to the main body 1, the support 22 needs to be fixed in order to prevent the support 22 from shaking during the wind sweeping of the wind sweeping blade 21. Specifically, as shown in fig. 4 to 8, the indoor unit 100 of the air conditioner of the present invention may include a locking member 3. The locking member 3 is movable relative to the main body 1 to move to a first movable position, and when the supporting member 22 is located at the first position, the supporting member 22 is locked at the first position (as shown in fig. 6); and unlocking the support 22 when moved to the second active position (as shown in figures 7 and 8). In this example, when the support member 22 is located at the first position, the locking member 3 may lock and fix the support member 22, so that the support member 22 may be effectively prevented from shaking to affect the wind sweeping of the wind sweeping blade 21 thereon.

In the above example, as shown in fig. 8, when the locking member 3 moves to the second active position to unlock the supporting member 22, the supporting member 22 can drive the whole air sweeping mechanism 2 to move to the aforementioned second position, so as to allow the air outlet 10, and the user can conveniently clean the air outlet 10.

In order to facilitate the operation of the locking member 3, the locking member 3 may be moved to the first active position and the second active position, as shown in fig. 4 to 9, and the indoor unit 100 of the air conditioner of the present invention may further include a pressing structure, where the pressing structure includes a movable pressing member 4 and a first elastic member 5. The pressing member 4 is configured to drive the locking member 3 to move to the aforementioned second active position (as shown in fig. 7) when pressed, so that the locking member 3 unlocks the supporting member 22. As shown in fig. 8, the first elastic member 5 is used to drive the locking member 3 to move to the aforementioned first active position when the pressing member 4 is released. In this example, as shown in fig. 6, when the pressing member 4 is not pressed, the locking member 3 is located at the first active position, and when the supporting member 22 is located at the first position, the locking member 3 locks the supporting member 22 at the first position, so that the wind sweeping blade 21 on the supporting member 22 can sweep wind stably. As shown in fig. 7, when the user needs to clean the air outlet 10, the user presses the pressing member 4, the first elastic member 5 is compressed, and the pressing member 4 drives the locking member 3 to move to the aforementioned second active position, and the locking member 3 unlocks the supporting member 22, so that the supporting member 22 can drive the whole air sweeping mechanism 2 to leave the air outlet 10. As shown in fig. 8, when the user releases the pressing member 4, the first elastic member 5 returns to the initial position, and the first elastic member 5 applies a force to the locking member 3, so that the locking member 3 returns to the first active position.

What needs to be explained here is: the pressing member 4 may be disposed on an outer surface of the air conditioning indoor unit 100 to facilitate the user's operation of the pressing member 4. As shown in fig. 9, the pressing member 4 may be a button or the like, and the outer edge of the button may be provided with a skirt for limiting the main body 1 such as a panel body, so as to prevent the button from being ejected out of the panel body due to the excessive elastic force of the first elastic member 5. Meanwhile, enough space is reserved between the button and the bottom shell inside the air conditioner indoor unit 100 to ensure the pressing stroke of the button, and the bottom shell can also serve as a limiting structure of the button.

Further, in order to achieve the technical effect of driving the locking member 3 to move to the second active position when the pressing member 4 is pressed, the present invention further provides the following technical scheme: as shown in fig. 9, the aforementioned pressing member 4 includes a base 41. The middle part of the base 41 is hinged to the main body 1. The base 41 has a pressing portion 411 at one end and a hook portion 412 at the other end. The hook portion 412 is configured to cooperate with the locking member 3 to hook the locking member 3 when the pressing portion 411 is pressed, and drive the locking member 3 to move to the second active position. In this example, the base 41 cooperates with the main body 1 to form a lever structure, and when the pressing portion 411 at one end of the base 41 is pressed, the hook portion 412 at the other end of the base 41 can quickly respond.

As shown in fig. 9, the pressing portion 411 may be a part of the base 41 itself, that is, the pressing portion 411 may be integrally formed on the base 41. Similarly, the hook 412 may be a part of the base 41 itself, that is, the hook 412 may be integrally formed on the base 41.

What needs to be explained here is: as shown in fig. 5, the main body 1 may be provided with a guiding chute 101, and the guiding chute 101 may guide the locking member 3, so that the locking member 3 may move to the first active position and the second active position, thereby ensuring the movement accuracy of the locking member 3.

Further, as shown in fig. 5, the locking member 3 may be provided with a limiting structure 30, such as a limiting boss, for limiting the displacement of the locking member 3 along the guiding chute 101, so that the locking member 3 may just slide in the guiding chute 101 to the first active position and the second active position, thereby ensuring the accuracy and precision of the displacement of the locking member 3.

As shown in fig. 9, the aforementioned first elastic member 5 may be disposed between the pressing portion 411 and the locking member 3. One end of the elastic member may be fastened to the locking member 3 by means of a snap connection, and the other end abuts against the lower portion of the pressing portion 411.

The first elastic member 5 may be elastic rubber, a compression spring, or the like.

In order to achieve the above-mentioned effect that the locking member 3 can lock the supporting member 22 in the first position, as shown in fig. 6 to 8, the locking member 3 may be provided with an insertion portion 31, and the supporting member 22 is provided with a first clamping groove 211. When the locking member 3 moves to the first active position and the supporting member 22 is located at the first position, the insertion portion 31 of the locking member 3 is inserted into the first clamping groove 211, so as to lock the supporting member 22 at the first position in a clamping manner; when the locking member 3 moves to the second active position, the insertion portion 31 of the locking member 3 exits the first clamping groove 211 to unlock the support member 22.

The locking member 3 may be plate-shaped, and the insertion portion 31 is a part of the locking member 3 and is located at one end of the locking member 3.

Further, in order to achieve the technical effect that the support 22 can rotate relative to the main body 1, as shown in fig. 10, the main body 1 may be provided with a first connecting shaft 11. The support 22 has a plate shape, and one end of the support 22 is provided with a first shaft hole 221. The side of the first shaft hole 221 is provided with a first opening into which the first coupling shaft 11 is fitted. Wherein the support 22 is rotated to the aforementioned first and second positions with respect to the main body 1 by the first connection shaft 11. In this example, the first connection shaft 11 is fitted into the first shaft hole 221 through a first opening on the side of the first shaft hole 221, thereby completing the connection between the support 22 and the main body 1.

As shown in FIG. 10, the width L1 of the first opening is equal to or less than 2R1, wherein R1 is the radius of the first connecting shaft 11, so as to ensure that the supporting member 22 does not fall out of the main body 1 in the working position.

As shown in fig. 10, in order to facilitate the insertion of the first coupling shaft 11 into the first shaft hole 221, a tangential plane may be provided at a side portion of the first coupling shaft 11. Wherein the width of the first connecting shaft 11 is smaller than or equal to the width L1 of the first opening so that the supporting member 22 can be smoothly fitted into the main body 1 at the assembling position. The radius R1 of the first coupling shaft 11 is equal to or less than the radius of the first shaft hole 221 so that the supporter 22 can be rotated in the first shaft hole 221 by the first coupling shaft 11.

Further, as shown in fig. 11 and 12, the main body 1 may be provided with a second connecting shaft 12, and the second connecting shaft 12 is sleeved with a torsion spring 7. As shown in fig. 3, one end of the torsion spring 7 is engaged with the main body 1, and the other end is engaged with the support 22, and the torsion spring 7 is used to provide a force for moving the support 22 from the aforementioned first position to the second position. In this example, through the torsion spring 7 provided, when the locking member 3 unlocks the support member 22, the support member 22 can automatically move from the first position to the second position under the action of the torsion spring 7, so as to leave the air outlet 10 open, thereby having the technical effect of saving manpower.

Wherein the diameter of the second connecting shaft 12 is smaller than or equal to the inner diameter of the torsion spring 7, so that the torsion spring 7 can be sleeved on the second connecting shaft 12.

Further, as shown in fig. 11, the main body 1 is provided with two connection portions 102, and the number of connection portions 102 is two and is set at intervals. One end of the second connecting shaft 12 is connected to one connecting portion 102, and the other end is connected to the other connecting portion 102. The torsion spring 7 is located between the two connection portions 102.

As shown in fig. 11, the connecting portion 102 may be provided with a second shaft hole 1021, and a second opening into which the second connecting shaft 12 is fitted may be provided in a side portion of the second shaft hole 1021. Wherein the width L2 of the second opening is smaller than or equal to the diameter of the second connecting shaft 12 and smaller than or equal to the diameter of the second shaft hole 1021, so as to ensure that the second connecting shaft 12 cannot fall out after being installed in the second shaft hole 1021.

As shown in fig. 12, the body 1 may be provided with a protrusion 103, and an accommodating space 1031 for accommodating the torsion spring 7 is provided in the protrusion 103, and the accommodating space 1031 may be in a shaft hole shape, so that the outer diameter of the torsion spring 7 is smaller than or equal to the inner diameter of the shaft hole in order to enable the torsion spring 7 to be accommodated in the shaft hole. The aforementioned protrusion 103 has an arc-shaped outline. The support 22 is provided with an arc-shaped recess 222 and can be rotated about the protrusion 103 to the aforementioned first and second positions by the arc-shaped recess 222.

Wherein, the outer diameter of the arc outline of the protrusion 103 is smaller than or equal to the inner diameter of the arc groove 222 of the support member 22, so that the support member 22 can smoothly rotate around the main body 1.

In a specific application example, the air outlet 10 is arranged vertically. As shown in fig. 1 and 2, one end of the support member 22 is rotatably disposed at the upper end of the air outlet 10, so as to drive the air sweeping mechanism 2 to rotate to the first position and the second position, when the support member 22 drives the air sweeping mechanism 2 to rotate from the first position to the second position, the air sweeping mechanism 2 is located above the air outlet 10, so that the air outlet 10 can be completely yielded, interference to the line of sight and manual space of a user can be avoided, and the air outlet 10 can be conveniently cleaned by the user.

Of course, in an alternative example, one end of the supporting member 22 may be rotatably disposed at the lower end of the air outlet 10, so as to drive the air sweeping mechanism 2 to rotate to the first position and the second position. The technical effect that the air sweeping mechanism 2 gives off the air outlet 10 can be achieved.

Further, as shown in fig. 6, the main body 1 may include a volute tongue 6 and an air duct, where the air duct is connected to the air outlet 10. In the first position, the supporting member 22 forms a part of the inner wall of the air duct and cooperates with the volute tongue 6 through the spigot, so as to prevent air leakage from interfering with the components of the air conditioner indoor unit 100 located outside the air duct.

Further, as shown in fig. 13 and 14, the main body 1 may be provided with a limiting slot 104, and the support 22 may be provided with a limiting boss 223. Wherein, the supporting member 22 is clamped with the limiting clamping groove 104 through the limiting boss 223 when moving to the second position, so as to position the supporting member 22, and prevent the supporting member 22 from falling down under the action of gravity to affect cleaning.

Wherein, the limiting boss 223 of the supporting member 22 and the limiting slot 104 can be provided with guiding structures, so that the limiting boss 223 of the supporting member 22 can be smoothly clamped into and withdrawn from the limiting slot 104.

What needs to be explained here is: the main body 1 may include a panel body, and the first connecting shaft 11, the second connecting shaft 12, the connecting portion 102, the protrusion 103, and the limiting slot 104 may be disposed on the panel body.

As shown in fig. 15, the air conditioning indoor unit 100 of the present invention may further include a motor, a crank 8, and a connecting rod 9. The motor is provided on the main body 1. The crank 8 is arranged on the output shaft of the motor. The connecting rod 9 is respectively connected with the crank 8 and the wind sweeping blade 21, and the connecting rod 9 is used for driving the wind sweeping blade 21 to sweep wind under the driving of the crank 8. Wherein, the connecting rod 9 is detachably connected with the crank 8. In this example, the electric wind sweeping blade 21 can sweep wind by the motor, the crank 8 and the connecting rod 9, thereby saving manpower. In addition, the connecting rod 9 is detachably connected with the crank 8, so that the action of the wind sweeping mechanism 2 for opening the air outlet 10 is not influenced when the connecting rod 9 is detached from the crank 8.

Of course, in an alternative example, the aforementioned motor may also be disposed on the support member 22, so that when the support member 22 drives the wind sweeping mechanism 2 to integrally turn over, the motor also turns over together, and the wind sweeping mechanism 2 will not be affected to release the air outlet 10. In this alternative example, the connection between the connecting rod 9 and the crank 8 may be fixed, or the detachable connection described above may be used.

In order to achieve the aforementioned technical effect of detachably connecting the connecting rod 9 and the crank 8, as shown in fig. 16 and 17, the indoor unit 100 of the air conditioner of the present invention may further include a connecting member 91 and a second elastic member 92. The connector 91 is rotatably provided at one end of the link 9 to be opened with respect to the link 9 when rotated to the first movement position; and is closed with respect to the connecting rod 9 when rotated to the second movement position, and cooperates with one end of the connecting rod 9 to form a second clamping groove therebetween for clamping the crank 8. The second elastic member 92 is used for providing a clamping force for clamping the crank 8 by the second clamping groove. In this example, the connecting member 91 and one end of the connecting rod 9 are fitted, both of which form a clip-like structure, and both of the connecting member 91 and the connecting rod 9 can be tightly held on the crank 8 by the fitting of the second elastic member 92.

The second elastic member 92 may be a torsion spring or the like.

In an alternative example, the aforementioned connecting rod 9 may also be detachably connected to the crank 8 by means of a snap-fit connection. Of course, how to implement the method can be set according to the actual needs of the user, and will not be described herein.
